Referring to FIG. 1 , the present application provides a communication system. The communication system includes a network device 101 and a terminal 102 .

Specifically, the terminal 102 may be a device that provides voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. Terminal 102 may communicate with one or more core networks via a radio access network (RAN). Terminal 102 may be a mobile terminal, such as a mobile telephone (or a "cellular" telephone).

For example, the base station may be a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA), or a broadband code division A base station (NodeB) in multiple access (wideband code division multiple access, WCDMA), may also be an evolved base station (evolutionalNode B, eNB or e-NodeB) in long term evolution (long term evolution, LTE), may also be the first The gNB in the fifth-generation mobile communication technology (5th-generation, 5G) is not limited in the embodiments of the present application.

Referring to FIG. 1 , the network device takes a base station as an example, and FIG. 2 shows a method for a terminal to apply for uplink resources in the prior art. Referring to Figure 2, the method includes:

201. The terminal sends an uplink scheduling request (scheduling request, SR) to the base station.

The SR is used to indicate that the data to be transmitted needs to be transmitted by the base station.

Specifically, FIG. 3 is a method for a terminal to send an uplink scheduling request in the prior art. Referring to FIG. 3 , the method includes the following steps.

300. The terminal determines that at least one SR is triggered.

301. The terminal determines whether there is a valid physical uplink control channel (physical uplink control channel, PUCCH) resource.

3011. If there is no valid PUCCH resource, trigger random access on spcell.

302. If there is a valid PUCCH resource, determine whether the SR prohibition timer (sr-ProhibitTimer) is started, whether the valid PUCCH resource coincides with the measurement gap, and the valid PUCCH resource and the physical uplink shared channel (physical uplink shared channel, PUSCH) Whether to coincide.

3021. If there is at least one condition in step 302 and the result is yes, release the PUCCH and sounding reference signal (SRS) of all serving cells, and clear the PUCCH whose channel state information (CSI) is semi-persistent. resources, initialize random access on spcell, cancel all pending SRs.

Among them, after the SR is triggered, it is considered to be a pending SR until it is cancelled.

303. If all the conditions in step 302 meet the negative result, determine whether the SR counter (SR_COUNTER) is less than the maximum number of SRs (sr-TransMax).

If the SR counter ≥ the maximum number of SRs, step 3021 is executed.

304. If the SR counter is less than the maximum number of SRs, add 1 to the SR counter (SR_COUNTER), send an SR to the base station on a valid PUCCH resource, and start an SR prohibition timer (sr-ProhibitTimer).

202. After receiving the SR, the base station issues uplink permission information to the terminal.

203. After receiving the uplink permission information, the terminal reports a buffer status report (buffer status reporting, BSR) to the base station.

The BSR is used to indicate the amount of data to be transmitted, so that the base station can allocate transmission resources for the data to be transmitted.

Specifically, the BSR usually includes a BS field and an LCG _i field, where the LCG _i field is used to indicate LCG-related information, and the BS field is used to indicate the amount of data to be transmitted. Among them, in the BSR in the short (short) format and the BSR in the short truncated (short truncated) format, the LCG _i field is used to indicate the identity document (ID) of the logical channel group corresponding to the BSR; in the BSR in the long (long) format , the LCG _i field is used to indicate whether the BS field of the logical channel group i exists; in the long truncated (long truncated) format of the BSR, the LCG _i field is used to indicate whether there is data to be transmitted in the logical channel group i.

In addition, before reporting the BSR, the terminal can configure multiple logical channels (logical channels, LCs) into one LCG according to the strategy of the base station, and one terminal can support up to 8 LCGs. After that, the terminal sends a BSR on the LCG.

Specifically, before reporting the BSR, the terminal needs to determine the type of the triggered BSR. Further, the method for the terminal to trigger the BSR includes the following situations.

A1. When there is data to be transmitted on a logical channel (LC) in the LCG, and the priority of the LC is higher than the priority of other LCs to be transmitted, trigger the reporting of "regular BSR" type BSR.

Alternatively, when data to be transmitted on a certain LC needs to be sent, and there is no data to be transmitted on other LCs in the LCG where the LC is located, a BSR of the "regular BSR" type is triggered to be reported.

In addition, when the BSR retransmission timer (retxBSR-Timer) times out, and there is data to be transmitted on at least one LC in a certain LCG, a BSR of the "regular BSR" type is also triggered to be reported.

A2. When the terminal determines that in the uplink grant information issued by the base station, the idle resources in the uplink resources allocated to the terminal are greater than or equal to the data overhead of the BSR+header, trigger the reporting of a BSR of the "padding BSR" type.

A3. When the BSR periodic timer (periodicBSR-Timer) times out, trigger to report a BSR of the "periodic BSR" type.

The terminal determines the type of the triggered BSR, and then reports the BSR to the base station. Further, the method for reporting the BSR by the terminal includes the following steps.

Specifically, when the terminal triggers and reports BSRs of the "regular BSR" and "periodic BSR" types, the method for the terminal to report the BSR includes:

B. When there is more than one LCG to be transmitted, the BSR in the long BSR format is reported. Otherwise, the BSR in shortBSR format is reported.

When the terminal triggers and reports a BSR of the "padding BSR" type, the method for the terminal to report the BSR includes:

C1. If it is determined that in the uplink grant information issued by the base station, the idle resources in the uplink resources allocated for the terminal are equal to the data overhead of the BSR+ header in the short BSR format, and there is more than one LCG to be transmitted, report the shorttruncated BSR format. BSR.

C2. The terminal determines that in the uplink grant information issued by the base station, the idle resources in the uplink resources allocated to the terminal are equal to the data overhead of the BSR+header in the short BSR format, and there is only one LCG to transmit data, then report the shortBSR format. BSR.

C3. The terminal determines that in the uplink grant information issued by the base station, the idle resources in the uplink resources allocated to the terminal are greater than the data overhead of the BSR+header in the short BSR format, less than the data overhead of the BSR+header in the long BSR format, and more than one LCG If there is data to be transmitted, the BSR in the long truncated BSR format is reported.

C4. The terminal determines that in the uplink grant information issued by the base station, the idle resources in the uplink resources allocated to the terminal are greater than or equal to the BSR in the long BSR format + the data overhead of the header, and then report the BSR in the long BSR format.

The amount of data to be transmitted is carried in the BS field of the BSR. Specifically, in the 5G network, the BS field of the BSR in the shortBSR format and the short truncated BSR format has 5 bits, and the BS field of the BSR in the long BSR format and the longtruncated BSR format has 8 bits. Under the LTE network, the BS field of the BSR in the short BSR format and the short truncated BSR format has 6 bits, and the BS field of the BSR in the long BSR format and the long truncated BSR format has 8 bits. The embodiments of the present application are described in the format of the BSR under the 5G network, but it is also applicable to the format of the BSR under other networks.

More specifically, the field contents of the BSR in the short BSR format and the short truncated BSR format are shown in Figure 4. The _BSR field contents in the short BSR format and the short truncated BSR format are the same. BS field. The LCG _i field is used to indicate the ID of the LCG corresponding to the data to be transmitted, and the BS field is used to indicate the data amount of the data to be transmitted.

Further, the mapping table of the BSR in the short BSR format and the short truncated BSR format is as follows in Table 1. Wherein, BS represents the range of the data volume of the data to be transmitted, and the unit is bytes; the index represents an indirect indication of the data volume of the data to be transmitted, and the index corresponds to the BS in the BSR.

The field contents of the BSR in the long BSR format and the long truncated BSR format are shown in Figure 5. The field contents of the BSR in the long BSR format and the long truncated BSR format are the same, and the field contents include the LCG _i field and the BS field. Wherein, for the BSR in the long BSR format, the LCG _i field is used to indicate whether the BS field of the logical channel group i exists. For the BSR in the long truncated BSR format, the LCG _i field is used to indicate whether there is data to be transmitted in the logical channel group i.

Further, the mapping table of the BSR of the Long BSR format and the long truncated BSR format is as follows in Table 2, wherein, BS represents the range of the data volume of the data to be transmitted, and the unit is byte; the index represents the indirect indication of the data volume of the data to be transmitted, The index corresponds to the BS in the BSR.

Table 2

According to Table 1 and Table 2 above, it can be seen that compared with the BSR with the BS field of 5 bits, the range of the amount of data to be transmitted carried in the BSR with the BS field of 8 bits is more finely divided, that is, the larger the BS field, the corresponding The more BSs there are, the finer the range of the reported amount of data to be transmitted is divided. In this way, after receiving the BSR, the base station performs resource allocation according to the range of the data amount of the data to be transmitted carried in the BS field, and the allocated resources are more accurate.

Based on the above situation, the present application provides a communication method and apparatus. The communication method specifically includes: the network device adds the acquired identifier of the first LCG to the uplink permission information, and then sends the uplink permission information to the terminal. When determining that the received uplink grant information carries the identifier of the first LCG, the terminal sends the BSR in the first format to the network device through the first LCG according to a preset condition. Wherein, all fields in the BSR of the first format are used to indicate the data amount of the data to be transmitted. In this way, the terminal can report more information about the data volume of the data to be transmitted to the base station, so that the base station can allocate resources more accurately.

The communication method provided by the embodiment of the present application is described below with reference to the communication system shown in FIG. 1 and the communication apparatus shown in FIG. 6 .

FIG. 7 is a schematic flowchart of a communication method provided by an embodiment of the present application. Referring to Fig. 7, the communication method includes the following steps.

701. The network device acquires the identifier of the first LCG.

The identifier of the first LCG may be actively configured by the network device for the terminal, or may be acquired from an SR sent by the terminal.

Specifically, when the network device allocates uplink permission information to the terminal, it includes the following situations:

D1. The network device actively configures the LCG identifier for the terminal. At this time, the uplink permission information allocated by the network device to the terminal carries the identifier of the first LCG, and the identifier of the first LCG is the identifier of the LCG that the network device actively configures for the terminal.

D2. The network device receives the SR of the terminal and triggers the allocation of uplink permission information. At this time, the uplink grant information allocated by the network device to the terminal carries the identifier of the first LCG, and the identifier of the first LCG is the identifier of the LCG corresponding to the SR configuration (SR configuration) corresponding to the received SR.

Specifically, in the 5G network, in the SR configuration corresponding to the SR reported by the terminal, a specific LCG can be distinguished. Therefore, the network device can determine the identifier of the first LCG according to the SR configuration corresponding to the SR reported by the terminal.

D3. The network device does not receive the SR of the terminal, nor does it configure the LCG identifier for the terminal. At this time, the uplink grant information allocated by the network device to the terminal does not carry the identifier of the first LCG.

702. The network device adds the identifier of the first LCG to the uplink permission information.

For example, in a 5G network, the network device carries a 3-bit identifier of the first LCG in DCI0_0\DCI0_1 of the uplink license information.

703. The network device sends uplink permission information to the terminal.

704. The terminal determines that the uplink grant information includes the identifier of the first LCG, and sends the BSR in the first format to the network device through the first LCG according to a preset condition.

Wherein, all fields in the BSR of the first format are used to indicate the data amount of the data to be transmitted.

First, as shown in FIG. 8 , the present application provides a new BSR format, that is, the BSR of the first format in the present application. See FIG. 8 for the field content of the BSR in the first format, including the 8-bit BS field and excluding the LCG _i field. The BS field is used to indicate the amount of data to be transmitted.

Secondly, when the terminal receives the uplink grant information, it first determines whether the uplink grant information carries the identifier of the first LCG. The network device sends the BSR in the first format.

Specifically, as shown in FIG. 9 , the present application provides a method for reporting a BSR. The method for reporting the BSR includes the following steps.

901. The terminal determines whether the uplink grant information includes the identifier of the first LCG.

Specifically, if it is determined that the uplink grant information includes the identifier of the first LCG, the terminal executes step 902 . If it is determined that the identifier of the first LCG is not included in the uplink grant information, step 9011 is executed.

9011. The terminal sends the BSR in the second format to the network device.

Specifically, the BSR in the second format includes long BSR, short BSR, short truncated BSR, and long truncated BSR. For a specific manner in which the terminal sends the BSR in the second format to the network device, reference may be made to step B and steps C1-C4 in the prior art, and details are not described herein again.

902. The terminal determines whether data to be transmitted exists in at least two LCGs.

Specifically, if it is determined that there are data to be transmitted in at least two LCGs, the terminal executes step 903 . If it is determined that there is data to be transmitted in only one LCG, the terminal executes step 9021 .

9021. The terminal determines that there is data to be transmitted in the second LCG, and executes step 904.

The terminal corresponds to at least two LCGs, the at least two LCGs include a first LCG and a second LCG, and there is no data to be transmitted in the at least two LCGs except the second LCG.

903. The terminal determines whether the idle resource is equal to the first threshold.

Wherein, the uplink grant information further includes idle resources, and the idle resources are used to transmit the data amount of the data to be transmitted.

Specifically, if it is determined that the idle resource is equal to the first threshold, the terminal performs step 904 . If it is determined that the idle resource is not equal to the first threshold, the terminal performs step 9011. The value of the first threshold is "short BSR" + header overhead.

904. The terminal sends the BSR in the first format to the network device through the first LCG.

In the above solution, the network device adds the acquired identifier of the first LCG to the uplink permission information, and then sends the uplink permission information to the terminal. When the terminal determines that the received uplink grant information carries the identifier of the first LCG, according to a preset condition, the terminal sends the BSR in the first format to the network device through the first LCG. Wherein, all fields in the BSR of the first format are used to indicate the data amount of the data to be transmitted. In this way, because the network device specifies the first LCG for the terminal side to report the BSR, when the terminal reports the BSR, the LCG _i field may not be carried to provide more available space for the BS field. Further, all fields in the BSR of the first format are used to indicate the data amount of the data to be transmitted. Therefore, compared with the BSR including the BS field and the LCG _i field, the range of the data amount of the data to be transmitted in the BSR of the first format is divided more finely. After receiving the BSR in the first format, the base station performs resource allocation according to the range of the data amount of the data to be transmitted carried in the BS field, and the allocated resources are more accurate.

In this embodiment of the present application, the communication device may be divided into functional modules according to the above method embodiments. For example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The above-mentioned integrated modules can be implemented in the form of hardware, and can also be implemented in the form of software function modules. It should be noted that, the division of modules in the embodiments of the present application is schematic, and is only a logical function division, and there may be other division manners in actual implementation.

The present application provides a communication device, and the communication device may be a terminal or a part of the device in the terminal, such as a chip system in the terminal.

The communication apparatus is configured to perform the steps performed by the terminal in the above methods shown in FIG. 7 and FIG. 9 . The communication apparatus provided by the embodiments of the present application may include modules corresponding to corresponding steps.

In the case where each functional module is divided according to each function, FIG. 10 shows a possible schematic structural diagram of the communication device. As shown in FIG. 10 , the communication apparatus includes an obtaining module 1001 and a sending module 1002 .

The obtaining module 1001 is configured to obtain uplink permission information from a network device. For example, with reference to FIG. 7 , the obtaining module 1001 is configured to perform step 703 .
