Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flow chart of an SR configuration control method according to the present invention. The SR configuration control method of the present invention is described below with reference to fig. 1. As shown in fig. 1, the method includes:

step 101, acquiring the number of detected SRs in each time slot of the target cell.

It should be noted that the main execution unit in the embodiment of the present invention is a base station.

Specifically, a Medium Access Control (MAC) layer of the base station data link layer (L2) may obtain the number of SRs detected in each timeslot of the target cell through mathematical statistics, numerical calculation, and the like, and may mark the number of SRs detected in each timeslot of the target cell as n _ SR _ avg. And the target cell is a cell covered by the base station signal.

It should be noted that n _ SR _ avg may be the number of actually detected SRs per timeslot of the target cell. The base station MAC layer may obtain the number of SRs actually detected in each timeslot of the target cell based on a mathematical statistics method. n _ SR _ avg may also be the average number of SRs detected per slot by the target cell. The base station MAC layer may obtain the number of SRs actually detected in the current time slot of the target cell and the number of SRs actually detected in each historical time slot based on a mathematical statistics method, obtain the average number of SRs detected in each time slot of the target cell in a numerical calculation manner based on the number of SRs actually detected in the current time slot of the target cell and the number of SRs actually detected in each historical time slot, and update the average number of SRs detected in each time slot of the target cell based on the number of SRs actually detected in the next time slot of the target cell.

102, when the duration of the SR number greater than the first number threshold exceeds the first duration threshold, for each terminal residing in the target cell, issuing first downlink control information to the terminal, so that the terminal responds to the first downlink control information and transmits an SR based on the target SR configuration.

Specifically, the first number threshold may be determined according to actual conditions, and may be denoted as TH _ SR _ NUM _ UP. Can also be usedSo as to determine the first time length threshold value according to the actual situation, and can mark the first time length threshold value as T₁. In the embodiment of the invention, TH _ SR _ NUM _ UP and T are compared₁The specific value of (A) is not limited.

If the judgment shows that the duration of n _ SR _ avg being greater than TH _ SR _ NUM _ UP exceeds T₁Then, the MAC layer of the base station may report the first SR configuration indication to a Radio Resource Control (RRC) layer of the network layer (L3) of the base station, and may record the first SR configuration indication as SR _ IND 1.

After receiving the SR _ IND1 reported by the base station MAC layer, the RRC layer of the base station may store all SR configuration information of the current base station, and may record all SR configuration information as SR _ CFG 0.

After receiving the SR _ IND1 reported by the base station MAC layer, the RRC layer of the base station may also issue a first SR configuration message to the base station MAC layer, and may record the first SR configuration message as SR _ CFG 1.

After receiving the SR _ CFG1 sent by the base station RRC layer, the MAC layer of the base station may send first Downlink Control Information (DCI) to each terminal in the target cell, and may record the first Downlink Control Information as DCI _ SR _ CFG 1.

It should be noted that the DCI _ SR _ CFG1 may multiplex a Short message (Short Messages) format specified in DCI format 1_0 in section 7.3.1.2 of the 38.212 protocol, and the specific manner may include: the DCI _ SR _ CFG1 may be scrambled with a paging radio network temporary identity (P-RNTI); the first two bits of the content of DCI _ SR _ CFG1 are Short message indicators (Short Messages indicators) -2 bits and have a value equal to reserved bit 00 in table 7.3.1.2.1-1 in the 38.212 protocol; the third bit of the DCI _ SR _ CFG1 content is 0; the subsequent content of DCI _ SR _ CFG1 is filled up in Short Messages format; the DCI _ SR _ CFG1 is scheduled according to the Short Messages scheduling rules. Table 1 is table 7.3.1.2.1-1 in the 38.212 protocol.

Table 138.212 protocol Table 7.3.1.2.1-1 Short Message indicator

The DCI _ SR _ CFG1 in the embodiment of the present invention adopts a short messages reserved bit mode in the multiplexing 38.212 protocol, which can avoid notifying each terminal in the target cell by means of RRC signaling, thereby avoiding generating a large amount of additional signaling overhead. SR _ CFG1 is issued to the base station MAC through the base station RRC layer, short messages flows can be multiplexed, and the operation efficiency is improved.

For each terminal in the target cell, after receiving the DCI _ SR _ CFG1 sent by the base station RRC layer, the terminal may store, in response to the DCI _ SR _ CFG1, SR configurations of the current terminal configuration, and may record the SR configurations as RRC _ SR _ CFG 1.

The terminal may determine a target SR configuration of the terminal according to a predetermined peer-to-peer agreement between the terminal and the base station based on the rrc _ SR _ cfg1 of the terminal, and may record the target SR configuration as SR _ cfg _ h. Each terminal in the target cell is configured with only one SR configuration at most.

It should be noted that, according to the predetermined peer-to-peer agreement between the terminal and the base station, the SR with the highest priority level in the rrc _ SR _ cfg1 of the terminal may be configured as the SR _ cfg _ h of the terminal; alternatively, one SR of the rrc _ SR _ cfg1 of the terminal may also be configured as the SR _ cfg _ h of the terminal based on actual requirements. In the embodiment of the present invention, the predetermined peer-to-peer agreement between the terminal and the base station is not specifically limited.

After determining the sr _ cfg _ h of the terminal, the terminal may retain only the sr _ cfg _ h. The SR of all the logical channels of the terminal is no longer sent according to the original configuration rule, and the SR is sent based on SR _ cfg _ h of the terminal.

It should be noted that the original configuration rule may be a rule that the terminal sends the SR before the base station issues the DCI _ SR _ CFG1, that is, each terminal may send the SR to the base station based on SR _ CFG 0. The original configuration rule may be determined according to actual conditions, and is not specifically limited in the embodiment of the present invention.

It should be noted that the terminal may also store the current SR configurations for standby.

It should be noted that, after the base station RRC layer issues the DCI _ SR _ CFG1, the ue of the new access base station will not receive the DCI _ SR _ CFG1, and the ue of the new access base station retains the original SR configurations and sends the SRs according to the original configuration rule.

When the physical layer of the base station detects and schedules all the SRs in the target cell in each time slot, the detected SRs are only the SRs sent by each terminal in the target cell based on the SR _ cfg _ h of the terminal, so that the number of the SRs detected and scheduled in each time slot of the physical layer of the base station is greatly reduced, and the average time consumption for detecting and scheduling the SRs in each time slot of the physical layer of the base station is reduced.

Based on the content of the foregoing embodiments, when the duration that the number of SRs is greater than the first number threshold exceeds the first duration threshold, for each terminal camping in the target cell, issuing the first downlink control information to the terminal, so that the terminal responds to the first downlink control information, and after the SR is configured and transmitted based on the target SR, the method further includes: and under the condition that the duration of the SR number which is not more than the second number threshold exceeds the second duration threshold, issuing second downlink control information to the terminal, so that the terminal responds to the second downlink control information and sends the SR based on the original configuration rule.

Specifically, the second quantity threshold may be determined according to actual conditions, and may be denoted as TH _ SRNUM DOWN. The second duration threshold value can also be determined according to the actual situation, and can be recorded as T₂. In the embodiment of the invention, TH _ SR _ NUM _ DOWN and T are compared₂The specific value of (A) is not limited.

It should be noted that TH _ SR _ NUM _ DOWN in the embodiment of the present invention is smaller than TH _ SR _ NUM _ UP.

After the physical layer of the base station only detects and schedules the SR sent by each terminal in the target cell based on the SR _ cfg _ h of the terminal, if the time length of n _ SR _ avg less than or equal to TH _ SR _ NUM _ DOWN exceeds T by judgment₂Then, the MAC layer of the base station may report a second SR configuration indication to the RRC layer of the base station, and may record the second SR configuration indication as SR _ IND 2.

After receiving the SR _ IND2 reported by the base station MAC layer, the base station RRC layer may issue a second SR configuration message to the base station MAC layer, and may use SR _ CFG0 as the second SR configuration message SR _ CFG2, thereby simplifying the calculation process of the configuration information of the base station RRC layer.

After receiving the SR _ CFG2, the MAC layer of the base station may issue second downlink control information to each terminal in the target cell, and may record the second downlink control information as DCI _ SR _ CFG 2.

It should be noted that the DCI _ SR _ CFG2 may multiplex a Short message (Short Messages) format specified in DCI format 1_0 in section 7.3.1.2 of the 38.212 protocol, and the specific manner may include: the DCI _ SR _ CFG2 may be scrambled with a paging radio network temporary identity (P-RNTI); the first two bits of the content of DCI _ SR _ CFG2 are Short message indicators (Short Messages indicators) -2 bits and have a value equal to reserved bit 00 in table 7.3.1.2.1-1 in the 38.212 protocol; the third bit of the DCI _ SR _ CFG2 content is 0; the subsequent content of DCI _ SR _ CFG1 is filled up in Short Messages format; the DCI _ SR _ CFG2 is scheduled according to the Short Messages scheduling rules. Wherein, table 7.3.1.2.1-1 in the 38.212 protocol is detailed in table 1.

The DCI _ SR _ CFG2 in the embodiment of the present invention adopts a short messages reserved bit mode in the multiplexing 38.212 protocol, which can avoid notifying each terminal in the target cell by means of RRC signaling, thereby avoiding generating a large amount of additional signaling overhead. SR _ CFG2 is issued to the base station MAC through the base station RRC layer, short messages flows can be multiplexed, and the operation efficiency is improved.

For each terminal in the target cell, after receiving the DCI _ SR _ CFG2 sent by the base station RRC layer, the terminal may delete SR _ CFG _ h of the terminal in response to the DCI _ SR _ CFG2, recover the RRC _ SR _ CFG1 of the terminal that is already stored by the terminal, and send an SR according to the original configuration rule based on the RRC _ SR _ CFG1 of the terminal that is already stored.

The physical layer of the base station can detect and schedule the SR sent by each terminal in the target cell according to the original configuration rule based on the stored rrc _ SR _ cfg1 of the terminal, so as to meet more diversified service requirements under the condition that the number of terminals residing in the target cell is small or the number of the SRs detected and scheduled per timeslot of the physical layer of the base station is small.

In the embodiment of the invention, after the base station determines that the time length for which the number of the SRs detected in each time slot of the target cell is not more than the second number threshold exceeds the second time length threshold, the terminal sends the second downlink control information to each terminal in the target cell, responds to the second downlink control information and sends the SR based on the original configuration rule, so that more diversified service requirements can be met under the condition that the number of the terminals residing in the target cell is less or the number of the SRs detected in each time slot of the target cell by the base station is less.

Fig. 2 is a second flowchart of the SR configuration control method according to the present invention. The SR configuration control method of the present invention is described below with reference to fig. 2. As shown in fig. 2, the method includes: step 201, receiving first downlink control information sent by a base station. The first downlink control information is sent by the base station under the condition that the time length of the SR number detected by the target cell in each time slot, which is greater than the first number threshold, exceeds the first time length threshold.

It should be noted that the execution subject of the embodiment of the present invention is each terminal in the target cell. The target cell is a cell covered by a base station signal.

Specifically, after the base station MAC layer obtains the number n _ SR _ avg of SRs detected in each timeslot of the target cell, if it is determined that n _ SR _ avg is large, the base station MAC layer learnsThe duration of time at TH _ SR _ NUM _ UP exceeds T₁The base station MAC layer may report the first SR configuration indication SR _ IND1 to the base station RRC layer. Wherein, TH _ SR _ NUM _ UP is a first quantity threshold value determined according to actual conditions; t is₁The first time length threshold value is determined according to actual conditions. In the embodiment of the invention, TH _ SR _ NUM _ UP and T are compared₁The specific value of (A) is not limited.

After receiving the SR _ IND1 reported by the base station MAC layer, the base station RRC layer may also issue a first SR configuration message SR _ CFG1 to the base station MAC layer.

After receiving SR _ CFG1 sent by the base RRC layer, the MAC layer of the base station may send first downlink control information DCI _ SR _ CFG1 to each terminal in the target cell.

For each terminal in the target cell, the terminal may receive DCI _ SR _ CFG1 issued by the RRC layer of the base station.

Step 202, responding to the first downlink control information, and configuring a transmission SR based on the target SR. Wherein the target SR configuration is determined based on the current SR configurations of the terminal.

Specifically, for each terminal in the target cell, after the terminal receives the DCI _ SR _ CFG1 sent by the RRC layer of the base station, the terminal may determine the target SR configuration SR _ CFG _ h of the terminal according to a predetermined peer-to-peer agreement between the terminal and the base station based on the RRC _ SR _ CFG1 of the terminal.

After the SR _ cfg _ h of the terminal is determined, the SRs of all logical channels of the terminal are not sent according to the original configuration rule any more, and the SRs are sent based on the SR _ cfg _ h of the terminal.

In the embodiment of the invention, after the base station determines that the time length of the SR detected in each time slot of the target cell, which is greater than the first number threshold, exceeds the first time length threshold, the base station transmits the first downlink control information to each terminal in the target cell, the terminal responds to the first downlink control information and transmits the SR based on the target SR configuration determined according to the current SR configuration of the terminal, the base station only detects and schedules the SR transmitted by the terminal based on the target SR configuration, and the number of the SRs detected and scheduled in each time slot of the base station can be reduced under the condition that the number of the terminals residing in the target cell is large or the number of the SRs detected in each time slot of the target cell is large, so that the average time consumed for detecting and scheduling the SR in each time slot of the base station can be reduced, the detection and scheduling overtime of the SR by the base station can be avoided, and the control on the SR configuration is more flexible, The method is more efficient and can improve the communication quality.

Based on the content of the foregoing embodiments, the method further includes: receiving second downlink control information sent by the base station; and the second downlink control information is sent by the base station under the condition that the time length of the SR number not greater than the second number threshold exceeds the second time length threshold.

Specifically, after the physical layer of the base station detects and schedules only the SR sent by each terminal in the target cell based on SR _ cfg _ h of the terminal, if it is known by judgment that the duration of n _ SR _ avg being less than or equal to TH _ SR _ NUM _ DOWN exceeds T₂The base station MAC layer may report the second to the base station RRC layerThe SR configuration indicates SR _ IND 2. Wherein, TH _ SR _ NUM _ DOWN is a second quantity threshold value determined according to actual conditions; t is₂The second duration threshold is determined according to actual conditions. In the embodiment of the invention, TH _ SR _ NUM _ DOWN and T are compared₂The specific value of (A) is not limited.

After receiving the SR _ IND2 reported by the base station MAC layer, the base station RRC layer may send a second SR configuration message SR _ CFG2 to the base station MAC layer using SR _ CFG 0.

After receiving the SR _ CFG2, the MAC layer of the base station may issue second downlink control information DCI _ SR _ CFG2 to each terminal in the target cell.

For each terminal in the target cell, the terminal may receive DCI _ SR _ CFG2 issued by the RRC layer of the base station.

And responding to the second downlink control information, recovering each stored SR configuration, and sending the SR according to the original configuration rule based on each SR configuration.

Specifically, for each terminal in the target cell, after receiving DCI _ SR _ CFG2 sent by the RRC layer of the base station, the terminal may respond to DCI _ SR _ CFG2 to recover the stored RRC _ SR _ CFG1 of the terminal, and send an SR based on the RRC _ SR _ CFG1 of the terminal and the original configuration rule; after the terminal receives the DCI _ SR _ CFG2 sent by the base station RRC layer, the terminal may also reconfigure each SR configuration of the terminal in response to the DCI _ SR _ CFG2, and send an SR based on each reconfigured SR configuration of the terminal and the original configuration rule.

The physical layer of the base station can detect and schedule the SR sent by each terminal in the target cell based on the original configuration rule, so that more diversified service requirements are met under the condition that the number of terminals residing in the target cell is less or the number of the SRs detected and scheduled in each time slot of the physical layer of the base station is less.

Based on the content of the foregoing embodiments, after receiving the first downlink control information sent by the base station, the method further includes: in response to the first downlink control information, current respective SR configurations are saved.

For each terminal in the target cell, after receiving the DCI _ SR _ CFG2 sent by the base station RRC layer, the terminal may respond to the DCI _ SR _ CFG2, store the current SR configurations RRC _ SR _ CFG1, and may only reserve the SR _ CFG _ h.

Correspondingly, the sending of the SR based on the original configuration rule specifically includes: and restoring each saved SR configuration and sending the SR based on each SR configuration and the original configuration rule.

For each terminal in the target cell, the terminal may recover the saved SR configurations, rrc _ SR _ cfg1, and send an SR based on rrc _ SR _ cfg1 and the original configuration rules.

The embodiment of the invention can meet more diversified service requirements under the condition that the number of terminals residing in the target cell is less or the number of the SRs detected by the base station in each time slot of the target cell is less by recovering the stored SR configuration of each terminal and each terminal sends the SR based on the SR configuration of each terminal and the original configuration rule.

In order to facilitate understanding of the SR configuration control method provided by the present invention, the SR configuration control method provided by the present invention is explained below by way of an example.
