In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device.

It should be appreciated that, for the sake of description, in the embodiment of the present invention, the multiple carriers or BWPs refer to multiple carriers or multiple BWPs; each carrier or BWP refers to each carrier or each BWP; the plurality of carrier groups or BWP groups refer to a plurality of carrier groups or BWP groups; single carrier or BWP refers to single carrier or single BWP.

As shown in fig. 1, a resource determining method according to an embodiment of the present invention is applied to a user equipment, and includes:

step 101, obtaining time domain resource indication information of downlink control information DCI, where the time domain resource indication information supports scheduling of multiple carriers or partial bandwidth BWP.

In this step, the time domain resource indication information of the DCI supports scheduling of multiple carriers or BWPs, and can schedule a single carrier or BWP. Therefore, by this step, the time domain resource indication information of the DCI is acquired, the scheduling of the network side device is known, and the next step is executed.

Step 102, determining scheduling time domain resources on multiple carriers or BWPs according to the time domain resource indication information.

In this step, after the time domain resource indication information supporting scheduling of multiple carriers or BWPs is obtained in step 101, the scheduling time domain resource corresponding to the time domain resource indication information on the multiple carriers or BWPs is determined according to the time domain resource indication information.

Therefore, according to step 101 and step 102, after the time domain resource indication information of the DCI is obtained, since the time domain resource indication information supports scheduling of multiple carriers or BWPs, the ue applying the method of the embodiment of the present invention can determine the scheduling time domain resources on multiple carriers or BWPs, so that it is possible to implement scheduling of multiple carriers or BWPs by using one DCI, and effectively reduce the overhead of the PDCCH during the scheduling process.

For example, when the method is applied to a DSS scenario, the network-side device generates and transmits DCI carrying time domain resource indication information, and the time domain resource indication information supports scheduling of multiple carriers or BWPs, so that the user-side device can acquire the time domain resource indication information after receiving the DCI, thereby determining scheduled time domain resources on the multiple carriers or BWPs.

It should be appreciated that the information carried by the DCI may be implemented by the corresponding field. Thus, optionally, in this embodiment, step 101 comprises:

determining the time domain resource indication information in a first indication domain corresponding to DCI according to the configuration information of the candidate resources scheduled by the DCI;

and obtaining the time domain resource indication information according to the first indication domain.

Here, the configuration information of the candidate resource scheduled by the DCI may be obtained through a configuration (e.g., high layer signaling configuration) or predefined manner, and the like, and then the user side device first determines that the time domain resource indication information is in the first indication domain corresponding to the DCI according to the configuration information, and then further obtains the time domain resource indication information from the first indication domain.

Optionally, in the first indication domain, subfields corresponding to carriers or BWPs are arranged according to a sequence of the first identifier; alternatively, the first and second electrodes may be,

the subzone corresponding to each carrier or BWP allocates high or low bits for the respective time domain resource indicator.

Wherein the first identity may be a cell identity ID, or a carrier indicator CIF, or a BWP ID. When the first identifiers are sorted according to the first identifier order, the first identifiers may be sorted from large to small, or may be sorted from small to large, and in this case, the sizes of the sub-fields corresponding to the carriers or BWPs in the first indication field may be the same or different. In addition, in the first indication domain, the sub-domain corresponding to each carrier or BWP may allocate a preset position, preferably a high bit or a low bit, for example, DCI schedules the cell1, and in the first indication domain, the sub-domain corresponding to the cell1 allocates a high bit for the time domain resource indication of the cell1, assuming that the sub-domain corresponding to the cell1 in the first indication domain is 5 bits and the time domain resource indication of the cell1 only needs 2 bits, the time domain resource indication of the cell1 is performed by using 2 bits in the 5-bit sub-domain corresponding to the cell1 in the first indication domain.

Optionally, in this embodiment, the determining, according to configuration information of candidate resources scheduled by DCI, that the time domain resource indication information is in a first indication domain corresponding to the DCI includes:

Obtaining the size of a second indication domain corresponding to each carrier or BWP according to the configuration information of each carrier or BWP in the candidate resources;

and determining the size of the first indication domain according to the size of the second indication domain.

Optionally, the determining, according to the second indication field, the size of the first indication field includes:

taking the sum of the sizes of all the second indication fields as the size of the first indication field; alternatively, the first and second electrodes may be,

and taking the size of the largest second indication domain in all the second indication domains as the size of the first indication domain.

In this way, after the size of the second indication domain corresponding to each carrier or BWP is obtained according to the configuration information of each carrier or BWP in the candidate resource, the sum of the sizes of all the second indication domains may be used as the size of the first indication domain, that is, the time domain resource allocation related domain of each carrier or BWP is scheduled by the DCI independently, and then preferably, the subfields corresponding to each carrier or BWP in the first indication domain are arranged according to the order of the first identifier. Taking Cell ID as an example, assuming that DCI can schedule Cell 1 and Cell 2, the size of a second indication domain, which is a time domain resource allocation correlation domain corresponding to Cell 1 and is obtained according to the configuration on Cell 1 and Cell 2, is S ₁The second indication field size corresponding to Cell 2 is S₂Then the first indication field size in the DCI is S₁+S₂And in the first indication field, the first S₁Each bit is a subfield (time domain distribution related field) corresponding to Cell1, and then S₂Each bit is a subfield corresponding to Cell 2.

In addition, all second indications may also be usedThe size of the largest second indication field in the field is used as the size of the first indication field, that is, the time domain resource allocation related field of each carrier or BWP scheduled by the DCI shares each carrier or BWP, and preferably, the sub-field corresponding to each carrier or BWP in the first indication field allocates high or low bits for the respective time domain resource indication. Taking Cell ID as an example, assuming that DCI can schedule Cell1 and Cell 2, the size of the second indicator field corresponding to Cell1 is obtained as S according to the configuration on Cell1 and Cell 2₁The second indication field size corresponding to Cell 2 is S₂Then the first indication field size in the DCI is max (S)₁，S₂) And in the first indication field, the sub-field corresponding to Cell1 is allocated as high (or low) S for its time-domain resource indication₁The subdomain corresponding to the bit and Cell 2 indicates the high (or low) S of the time domain resource allocation related domain₂And (6) bit. Therefore, suppose S₁>S₂Cell1 has its sub-domain assigned a high S for its time domain resource indication₁The subdomain corresponding to the bit and Cell 2 indicates that the time domain resource allocation related domain is low S ₂bit, if DCI schedules Cell 1, the first indication domain size of DCI is S₁bit, and a high S of the first indication field₁bit is the time domain resource indication of Cell 1; in case of DCI scheduling Cell 2, the first indication field size of DCI is S₁bit, and S₁Low S of bit₂bit is the time domain resource indication of Cell 2. Of course, the allocation indicated by the sub-domain corresponding to each carrier or BWP in the first indication domain for each time domain resource may be both high bits or both low bits.

In addition, considering that the candidate resource includes a plurality of carrier groups or BWP groups, for the plurality of carrier groups or BWP groups, optionally, the determining, according to the configuration information of the candidate resource scheduled by the DCI, that the time-domain resource indication information is in the first indication domain corresponding to the DCI includes:

when the candidate resource comprises a plurality of carrier groups or BWP groups, obtaining the size of a third indication domain corresponding to each carrier group or BWP group according to the configuration information of the plurality of carrier groups or BWP groups;

and determining the size of the first indication domain according to the size of the third indication domain.

Optionally, the determining the size of the first indication field according to the size of the third indication field includes:

taking the size of the largest third indication domain of all the third indication domains as the size of the first indication domain; alternatively, the first and second electrodes may be,

According to the formula L ═ S_MAXN is the size L of the first indicator domain, wherein S_MAXIndicating the size of a domain for a largest single carrier or BWP in the plurality of carrier groups or BWP groups, N being the largest number of carriers or BWPs in the plurality of carrier groups or BWP groups in the candidate resource; alternatively, the first and second electrodes may be,

and taking the size of the largest single carrier or BWP indication domain in the plurality of carrier groups or BWP groups as the size of the first indication domain.

In this way, after the size of the third indication field corresponding to each carrier group or BWP group is obtained according to the configuration information of the plurality of carrier groups or BWP groups, the size of the largest third indication field among all the third indication fields may be used as the size of the first indication field. When the DCI of the same size may schedule a plurality of carrier groups or BWP groups, the subfields corresponding to the carriers or BWPs in the first indication field may be arranged according to the first identifier. If the first indication field has the remaining bits after the arrangement, the remaining bits are invalid bits and can be set to all zeros. Alternatively, the subzone corresponding to each carrier or BWP in the first indication field may allocate high or low bits for the respective time domain resource indication.

For example, DCI schedulable carrier group 1 (including Cell 1 and Cell 2) and carrier group 2 (including Cell 3 and Cell 4) obtain, from respective configuration information of the 2 carrier groups, that the size of the third indication field corresponding to the carrier group 1 is 5 bits (where Cell 1 is 2 bits and Cell 2 is 3 bits), and that the size of the third indication field corresponding to the carrier group 2 is 10 bits (where Cell 3 is 4 bits and Cell 4 is 6 bits), then the size of the first indication field is 10 bits. Therefore, if the sub-fields corresponding to the carriers or BWPs in the first indication domain are arranged according to the sequence of the first identifier, for the carrier group 1, the first 2 bits of the first indication domain are the sub-fields corresponding to Cell 1, and the last 3 bits are the sub-fields corresponding to Cell 1; for the carrier group 2, the first 4 bits of the first indication field are the subfields corresponding to Cell 3, and the last 6 bits are the subfields corresponding to Cell 4. Thus, when the DCI schedules Cell 1 and Cell 2, of the 10 bits of the first indication field of the DCI, the first 2 bits are the subzone corresponding to Cell 1 (used for scheduling Cell 1), and the last 5 bits of the following 3 bits are the subzone corresponding to Cell 2, which may be set to all zeros.

In addition, the size of the largest single carrier or BWP indication field among the plurality of carrier groups or BWP groups may also be used as the size of the first indication field. The time domain resource allocation related domain (i.e. single carrier or BWP indication domain) required by each carrier or BWP of a plurality of carrier groups or BWP groups which DCI can be dispatched is S₁，S₂，…，S_KWherein K is the total number of all carriers or BWPs in the plurality of carrier groups or BWP groups that the DCI may be scheduled, the size of the first indication field is S_max，S_max＝max(S₁，S₂，…，S_K). When the DCI with the same size may schedule a plurality of carrier groups or BWP groups, it is preferable that the sub-domain corresponding to each carrier or BWP in the first indication domain allocates high or low bits for the respective time domain resource indication. For example, DCI schedules carrier group 1 (including Cell 1 and Cell 2) and carrier group 2 (including Cell 3 and Cell 4), and obtains configuration information of each carrier or BWP, where Cell 1 is 2 bits, Cell 2 is 3 bits, Cell 3 is 4 bits, and Cell 4 is 6 bits, and the size of the first indication field is 6 bits. Assuming that the sub-fields corresponding to the carriers or BWPs in the first indication field indicate that the allocation of the respective time domain resources is high, when the DCI schedules Cell 1 and Cell 2, and of the 6 bits in the first indication field of the DCI, the first 2 bits are the sub-field degree corresponding to Cell 1, the last 3 bits are the sub-fields corresponding to Cell 2, and the last 1bit is an invalid bit, the allocation may be set to zero.

Or according to the formula L ═ S_MAXAnd obtaining the size L of the first indication domain by N, wherein N is the maximum carrier or BWP number of a plurality of carrier groups or BWP groups in the candidate resources. When the DCI of the same size may schedule a plurality of carrier groups or BWP groups, the sub-domains corresponding to the carriers or BWPs in the first indication domain are arranged according to the first identifier, wherein the sub-domains corresponding to the carriers or BWPs may all have the size of S_MAXbit, per S_MAXHigh S of bit_ibit or low S_ibit corresponds to the ith carrier or BWP. In addition, the sub-carriers or BWPs corresponding to the first indication fieldThe domain sizes may also be different, and the subzone size corresponding to each carrier or BWP is equal to the size of its time-domain resource indication.

For example, DCI schedules carrier group 1 (including Cell 1 and Cell 2) and carrier group 2 (including Cell 3 and Cell 4), and obtains configuration information of each carrier or BWP, where Cell 1 is 2 bits, Cell2 is 3 bits, Cell 3 is 4 bits, and Cell 4 is 6 bits, and the size of the first indicator field is 10 × 2 bits — 20 bits. Arranging subdomains corresponding to carriers or BWPs in the first indication domain according to the sequence of the first identifier, and then scheduling Cell 1 and Cell2 by DCI, wherein on one hand, in 20 bits of the first indication domain of DCI, the first 10 bits are subdomains corresponding to Cell 1, the second 10 bits are subdomains corresponding to Cell2, in addition, only high 2 bits or low 2 bits are used in the first 10 bits for indicating time domain resources of Cell2, and only high 3 bits or low 3 bits are used in the second 10 bits for indicating time domain resources of Cell 2; on the other hand, in 20 bits of the first indication field of the DCI, consecutive bits may be used to perform time domain resource indication of the Cell, and the sub-field corresponding to each Cell directly indicates the time domain resource of the Cell, so that the first 2 bits of the 20 bits are the sub-field corresponding to Cell 1, and the time domain resource indication of Cell2 is directly performed, and the last 3 bits are the sub-field corresponding to Cell2, and the time domain resource indication of Cell2 is performed, so that the last 15 bits are invalid bits and may be set to all zeros.

Optionally, in this embodiment, the determining, according to configuration information of candidate resources scheduled by DCI, that the time domain resource indication information is in a first indication domain corresponding to the DCI includes:

and obtaining the size of the first indication domain according to the configuration information of the reference carrier or the BWP in the candidate resources.

Here, the reference carrier or BWP is set in a configuration or predefined manner, and the size of the first indication field is obtained by referring to configuration information of the reference carrier or BWP. The reference carrier or BWP may be a secondary cell Pcell, a cell or BWP with a minimum or maximum cell ID, and a cell or BWP with a minimum or maximum subcarrier spacing SCS.

Optionally, in this embodiment, the determining, according to configuration information of candidate resources scheduled by DCI, that the time domain resource indication information is in a first indication domain corresponding to the DCI includes:

and selecting the size of the first indication domain according to a preset strategy according to the scheduling of whether the DCI is single carrier or BWP.

The preset strategy comprises the following steps:

if the DCI is the scheduling of a single carrier or BWP, obtaining the size of the first indication domain according to the configuration information of the scheduled carrier or BWP;

if the DCI is not scheduling of single carrier or BWP, obtaining a size of a fourth indication field corresponding to each carrier group or BWP group according to configuration information of multiple carrier groups or BWP groups in the candidate resource, and setting a size of a largest fourth indication field of all fourth indication fields as the size of the first indication field, or setting a size of a largest single carrier or single BWP indication field of the multiple carrier groups or BWP groups as the size of the first indication field, or setting a formula L 'to S' _MAXN is obtained as the size L 'of the first indication domain, wherein S'_MAXIndicating the size of a domain for a largest single carrier or BWP in the plurality of carrier groups or BWP groups, N being the largest number of carriers or BWPs in the plurality of carrier groups or BWP groups in the candidate resource; or, obtaining the size of the first indication field according to configuration information of a reference carrier or BWP in the candidate resource.

Thus, for scheduling that the DCI is single carrier or BWP, the size of the first indication field is obtained from the configuration information of the scheduled carrier or BWP, e.g. the size of the first indication field is equal to the size S of the scheduled carrier or BWP indication field obtained from the configuration information_single. For scheduling that the DCI is not single carrier or BWP, after obtaining the size of the fourth indication field corresponding to each carrier group or BWP group from the configuration information of the multiple carrier groups or BWP groups in the candidate resource, the size of the largest fourth indication field among all the fourth indication fields may be set as the size of the first indication field, or the size of the largest single carrier or BWP indication field among the multiple carrier groups or BWP groups may be set as the size of the first indication field, or S 'according to the formula L'_MAXN obtains the size L' of the first indication domain, or obtains the size of the first indication domain according to the configuration information of the reference carrier or BWP in the candidate resource Is small.

Here, the implementation of determining the first indication field for scheduling that the DCI is not single carrier or BWP is similar to the implementation of determining the size of the first indication field according to the size of the third indication field, and is not described herein again. The reference carrier or BWP is as described above.

Optionally, in this embodiment, step 102 includes:

if the DCI schedules a reference carrier or BWP, the scheduled time domain resource is the time domain resource indicated by the time domain resource indication information;

and if the DCI schedules the non-reference carrier or the BWP, the scheduling time domain resource is determined according to the time domain position of the reference carrier or the BWP.

Here, the reference carrier or BWP is set in a configuration or predefined manner, and the size of the first indication field is obtained by referring to configuration information of the reference carrier or BWP. The reference carrier or BWP may be a secondary cell Pcell, a cell or BWP with a minimum or maximum cell ID, and a cell or BWP with a minimum or maximum subcarrier spacing SCS. If the DCI schedules the reference carrier or the BWP, scheduling the time domain resource as the time domain resource indicated by the time domain resource indication information. If the DCI schedules the non-reference carrier or the BWP, the scheduling time domain resource is further determined according to the time domain position of the scheduling reference carrier or the BWP, such as the first slot, the last slot, or all slots that overlap with the time domain position of the scheduling reference carrier or the BWP. And the time position of the scheduled physical downlink shared channel PDSCH or physical uplink shared channel PUSCH is the symbol position of a symbol indication SLIV in a corresponding slot or a plurality of slots. Therefore, the overhead is saved, and the length and the position of the time domain resource allocated to each cell are consistent.

Optionally, in this embodiment, the time domain resource indication information includes:

and the second identifier is an indication identifier of the time domain resource.

In this way, when the time domain resource indication information of the DCI is shared for each carrier or BWP, multiple indication flags of the time domain resource may be configured, and the time domain resource indication may be implemented by using a specific indication flag and/or an offset value.

For example, the second identification combination of the time domain resource indication information of the plurality of cells may be configured: if the multiple cells are Cell 1 and Cell 2, assuming that Cell 1 and Cell 2 are respectively configured with 8 time domain resource allocation values, the indication index of the time domain resource allocation value of the second identifier and Cell 1 identifies Cell 1TDRA index, and the correspondence between the indication index of the time domain resource allocation value of Cell 2 and the corresponding Cell 1TDRA index is as shown in table 1 below:

TABLE 1

Second label	Cell 1TDRA index	Cell 2TDRA index
			0	1	2
1	2	3
			2	3	4
3	4	5
			4	5	6
5	6	7
			6	7	0
7	0	1

In another configuration, new TDRA tables (different from the separately scheduled TDRA tables) may be respectively configured for the carriers or BWPs included in the carrier group or BWP group, and combined to form a new combined TDRA table.

Optionally, the indicated portion of the specific time domain resource allocation of the joint TDRA table may be shared by multiple carriers or BWPs, for example, K0/K2 of cell 1, K0/K2 of cell 2 and shared SLIV are configured in the joint TDRA table.

Optionally, in this embodiment, the time domain resource indication information includes: first indication information and second indication information;

the first indication information is a shared indication of each carrier or BWP, and the second indication information is an independent indication of each carrier or BWP.

Optionally, the first indication information is a slot indication, and the second indication information is a symbol indication in a slot; alternatively, the first and second electrodes may be,

the first indication information is a symbol indication in a time slot, and the second indication information is a time slot indication.

In this way, the flexibility of indication of a part of time domain resource indication information can be enhanced, and the method is useful in a cell with different uplink UL and downlink DL configurations in a time division multiplexing TDD scenario.

Assuming two cells, cell 1 and cell 2, the slot indication (K0/K2) indicates independently for each carrier or BWP, and the intra-slot symbol indicates SLIV shared indication for each carrier or BWPWithin the domain of the time domain resource indication information, the former S₁bit indicates the K0/K2 value of cell 1, followed by S₂bit indicates the K0/K2 value for cell 2, last S₃bit indicates SLIV values for cell 1 and cell 2.

Furthermore, optionally, in this embodiment, after the step 102, the method further includes:

and if the scheduling time domain resource conflicts with the uplink and downlink configuration of the corresponding carrier wave or BWP, determining that the scheduling time domain resource is invalid.

In this way, when the TDD uplink and downlink configurations configured by the carrier group or the BWP group scheduled by the DCI are different, when the time domain resource scheduled by the DCI is inconsistent with the uplink and downlink configurations on one or more carriers, the scheduled resource is considered to be invalid. For example, the DCI schedules uplink transmission, and if the resource part symbol represented by the TDRA indicated on carrier 2 is configured as a downlink symbol, the UE regards the scheduling as invalid and does not transmit any data. At this time, the resources represented by the TDRA indicated on the carrier 1 do not collide, the uplink PUSCH scheduling is effective, and the UE transmits data.

In summary, after the time domain resource indication information of the DCI is acquired, since the time domain resource indication information supports scheduling of multiple carriers or BWPs, the scheduling time domain resource on the multiple carriers or BWPs can be determined, so that one DCI can schedule multiple carriers or BWPs, and the overhead of the PDCCH in the scheduling process is effectively reduced.

As shown in fig. 2, an embodiment of the present invention further provides a resource indication method applied to a network side device, where the method includes:

step 201, generating downlink control information DCI carrying time domain resource indication information, where the time domain resource indication information supports scheduling of multiple carriers or partial bandwidth BWP;

Step 202, sending the DCI to the user side device.

According to step 201 and step 202, the network side device applying the method of the embodiment of the present invention generates DCI carrying time domain resource indication information, and sends the DCI to the user side device because the time domain resource indication information supports scheduling of multiple carriers or BWPs, so that the user side device can determine to schedule time domain resources on multiple carriers or BWPs, and can implement scheduling of multiple carriers or BWPs by using one DCI, thereby effectively reducing the overhead of PDCCH in the scheduling process.

The user input unit 507 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the network-side device. Specifically, the user input unit 507 includes a touch panel 5071 and other input devices 5072. Touch panel 5071, also referred to as a touch screen, may collect touch operations by a user on or near it (e.g., operations by a user on or near touch panel 5071 using a finger, stylus, or any suitable object or attachment). The touch panel 5071 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 510, and receives and executes commands sent by the processor 510. In addition, the touch panel 5071 may be implemented in various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. In addition to the touch panel 5071, the user input unit 507 may include other input devices 5072. In particular, other input devices 5072 may include, but are not limited to, a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, a mouse, and a joystick, which are not described in detail herein.

Further, the touch panel 5071 may be overlaid on the display panel 5061, and when the touch panel 5071 detects a touch operation thereon or nearby, the touch operation is transmitted to the processor 510 to determine the type of the touch event, and then the processor 510 provides a corresponding visual output on the display panel 5061 according to the type of the touch event. Although in fig. 5, the touch panel 5071 and the display panel 5061 are two independent components to implement the input and output functions of the network-side device, in some embodiments, the touch panel 5071 and the display panel 5061 may be integrated to implement the input and output functions of the network-side device, and is not limited herein.
