Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.

In the uplink radio resource scheduling and allocating method of the existing 4G and 5G mobile communication systems, the terminal downlink service data triggers the terminal uplink service data response, and the method generally includes the following steps (as shown in fig. 1):

step 101: and the base station transmits downlink scheduling to the terminal and transmits downlink service data.

Step 102: and the terminal feeds back a downlink scheduling Harq Ack to the base station.

Step 103: the terminal sends an uplink Scheduling Request (SR) (scheduling request) signaling to the base station.

Step 104: the base station does not know how much uplink data the terminal has to transmit, and therefore allocates uplink resources sufficient for sending BSR (Buffer Status Report) to the terminal, and notifies the terminal through DCI (Downlink Control Information).

Step 105: and after receiving the uplink scheduling DCI, the terminal sends BSR on the allocated uplink resources to tell the base station how much data needs to be sent.

Step 106: and the base station allocates proper uplink wireless resources according to the BSR reported by the terminal and by combining the wireless channel environment, and informs the terminal through the DCI.

Step 107: and after receiving the uplink scheduling DCI, the terminal transmits uplink data on the allocated uplink resources.

Step 108: if the BSR received by the base station in step 107 is empty, the uplink data of the terminal is sent, and the base station releases the uplink grant of the terminal and does not perform uplink scheduling. Otherwise, the steps 106, 107 and 108 are repeated.

The conventional uplink wireless resource scheduling and allocating method has multiple signaling interaction steps and large scheduling delay. Especially for the uplink response data is small, signaling flow interaction, such as access flow signaling interaction, each downlink signaling needs to be issued after the uplink response signaling transmission of the previous downlink signaling is completed. Therefore, each uplink and downlink signaling interaction needs to go through all the flows from the step 101 to the step 108, which results in very large time delay of the whole access flow.

Meanwhile, each terminal of the SR resources is shared independently, and as the terminals grow, especially the terminals of the internet of things deployed in 4G and 5G networks need more independent SR resources, SR periods also increase, and the above problem will be more serious.

As shown in fig. 2, a current improved method includes that step 201 configures pre-allocated resources for SR request scheduling, after a base station receives an uplink scheduling request SR from a terminal in step 204, the base station allocates resources according to a preset value in step 205, and performs downlink scheduling in step 206, so that uplink data can be scheduled by uplink scheduling once with a probability.

However, the method still needs to wait for the uplink scheduling request SR, the time delay is still equivalent to that of the conventional uplink radio resource scheduling method, and since the uniform SR request pre-allocation resources are set, if the set SR request pre-allocation resources are too small, the uplink response data still needs to be scheduled for many times, and if the set SR request pre-allocation resources are too large, the uplink response data is small, which causes resource waste.

The inventor finds that, generally, a downlink service and an uplink service of the same terminal have a certain correlation, and terminal-specific downlink data may trigger the terminal to perform uplink data response, for example, a downlink RRCSetup message of an access procedure may trigger the terminal to perform uplink RRCSetup complete. In the existing interactive mode, if a terminal wants to send uplink data to a base station (the data sent by the base station to the terminal is downlink data, and the data sent by the terminal to the base station is uplink data), the base station needs to uniformly allocate radio resources, and the terminal can send the data on the radio resources allocated by the base station. If the base station can directly judge to carry out downlink authorization according to the downlink service, the signaling interaction process is simplified.

Therefore, an embodiment of the present invention provides an uplink radio resource scheduling method, including: and judging whether uplink wireless resources need to be allocated to the terminal according to the downlink service.

The main executing body of the method may be a Base Transceiver Station (BTS) in a Global System for mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, or an evolved Base Station (evolved Node B, eNB, or eNodeB) in a Long Term Evolution (LTE) System. Optionally, an execution main body of the method may also be a NeXt Generation Radio Access Network (NGRAN), or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or may be a relay station, an Access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a Network device in a Public Land Mobile Network (PLMN) for future evolution, or the like.

Terminals include, but are not limited to: via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a Digital cable, a direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or means of another terminal device arranged to receive/transmit communication signals; and/or Internet of Things (IoT) devices. Terminal devices that are arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", or "mobile terminals". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communications Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data Communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. Terminal Equipment may refer to an access terminal, User Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, User terminal, wireless communication device, User agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having Wireless communication capabilities, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved PLMN, etc.

The method directly judges whether the uplink wireless resources are required to be allocated to the terminal according to the downlink service, and does not need to wait for the terminal to send the uplink scheduling request SR signaling, thereby simplifying the signaling interaction process, reducing the time delay and simultaneously not influencing the existing downlink service.

Specifically, the judgment content in the method includes: and judging whether the downlink service triggers the uplink service.

In a possible embodiment, the determining means includes: and judging whether the downlink service triggers the uplink service according to the base station signaling service. On this basis, in a further embodiment, the determining means includes: and judging whether the downlink service triggers the uplink service according to the specific signaling message.

In a possible embodiment, the determining means further includes: and judging whether the downlink service triggers the uplink service according to the base station data service. On this basis, in a further embodiment, the determining means includes: according to the QFI (qos Flow id) or QCI (qos class identifier) identifier of the base station data service, it is determined whether the downlink service triggers the uplink service, for example, whether the QFI or QCI identifier is a preset value is determined.

If the downlink service triggers the response of the uplink service data, it is also necessary to judge whether the downlink service is successfully sent, and if the downlink service is failed to send, the response of the uplink service data is not triggered.

Therefore, in a possible embodiment, the method for scheduling uplink radio resources further includes determining whether the downlink traffic is successfully transmitted. The base station may determine by receiving a scheduling result fed back by the terminal, for example: judging whether the downlink service is successfully transmitted according to the initial transmission scheduling result, and if the initial transmission scheduling fails, further judging whether the downlink service is successfully transmitted according to the retransmission scheduling result; if the retransmission scheduling fails, whether the downlink service is successfully sent is judged according to the RCL retransmission result.

In addition, if the terminal is already in the uplink grant state, then no more grant is needed, so in a possible embodiment, the determining whether to allocate uplink radio resources to the terminal according to the downlink service further includes determining whether the terminal is in the uplink grant.

Whether the terminal is in the uplink authorization can be judged according to whether the base station is processing the uplink service of the terminal.

Specifically, when the base station is in any one of the following scenarios, it may be determined that the terminal is in uplink grant:

a) the base station receives the SR request and does not issue the uplink scheduling;

b) the base station is processing the last uplink fast authorization and does not issue uplink scheduling;

c) the base station maintains non-empty of terminal uplink BSR information;

d) the base station sends down the uplink scheduling and does not receive the feedback of the uplink scheduling;

e) and the base station sends down uplink scheduling and receives uplink data, and updates terminal BSR information maintained by the base station according to the BSR carried by the uplink data, wherein the BSR is not empty.

And if the base station is not in the scene, judging that the terminal is not in the uplink authorization.

In a possible embodiment, the method further comprises: and predicting and allocating the uplink wireless resources to the terminal according to the downlink service.

By estimating the allocation amount of the uplink radio resource, the terminal can directly allocate the appropriate uplink radio resource to the terminal without sending a Buffer Status Report (BSR), so that the signaling interaction process can be further simplified.

In a possible embodiment, the estimated approach may be: and estimating and allocating the uplink wireless resources to the terminal according to the downlink signaling for the corresponding specific uplink response signaling overhead. And predicting how much uplink wireless resources are allocated to the terminal according to the preset value of the QFI or QCI identifier. And predicting and allocating the uplink wireless resources to the terminal according to the quantity of the downlink services identified by the QFI or the QCI.

It can be seen that the step of predicting the allocation amount of the uplink radio resource can also achieve the effect of simplifying signaling interaction, so another embodiment of the present invention further provides a method for scheduling uplink radio resources, which is executed by a base station, and includes: and predicting and allocating the uplink wireless resources to the terminal according to the downlink service.

Also in a possible embodiment, the way to estimate may be: and estimating and allocating the uplink wireless resources to the terminal according to the downlink signaling for the corresponding specific uplink response signaling overhead. And predicting how much uplink wireless resources are allocated to the terminal according to the preset value of the QFI or QCI identifier. And predicting and allocating the uplink wireless resources to the terminal according to the quantity of the downlink services identified by the QFI or the QCI.

Meanwhile, uplink scheduling resources are reasonably distributed according to the size of the estimated uplink response data, and the waste of the scheduling resources is avoided.
