Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

It should be understood that the technical solution of the present invention can be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, abbreviated as "GSM") system, code division multiple access (Code Division Multiple Access, abbreviated as "CDMA") system, wideband code division multiple access (Wideband Code Division Multiple Access, abbreviated as "WCDMA") system, general packet radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, abbreviated as "LTE") system, long term evolution advanced (Advanced long term evolution, abbreviated as "LTE-a") system, general mobile communication system (Universal Mobile Telecommunication System, abbreviated as "UMTS"), 5G, and the like.

Fig. 1 illustrates a wireless communication system 100 suitable for use with embodiments of the present invention. The wireless communication system 100 may include at least one network device, such as the first network device 110 and the second network device 120 shown in fig. 1. Both the first network device 110 and the second network device 120 may communicate with the terminal device 130 over a wireless air interface. The first network device 110 and the second network device 120 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within the coverage area. The first network device 110 or the second network device 120 may be a base station (Base Transceiver Station, abbreviated as "BTS") in a GSM system or a CDMA system, a base station (NodeB) in a WCDMA system, an evolved base station (Evolutional Node B, abbreviated as "eNB" or "eNodeB") in an LTE system, or a network device in a future 5G network, such as a transmission point (Transmission Reception Point, abbreviated as "TRP"), a base station, a small base station device, or the like, which is not particularly limited in the embodiment of the present invention.

The wireless communication system 100 further includes one or more terminal devices (UE) 130 located within the coverage of the first network device 110 and the second network device 120. The terminal device 130 may be mobile or stationary. Terminal device 130 may communicate with one or more Core networks (RANs) via a radio access Network (Radio Access Network), which may be referred to as an access terminal, a terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a subscriber terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, abbreviated "SIP") phone, a wireless local loop (Wireless Local Loop, abbreviated "WLL") station, a personal digital assistant (Personal Digital Assistant, abbreviated "PDA"), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, etc.

In the prior art, there are only two BSR formats for reporting BSR of logical channel groups:

1. one is a short BSR format (including Short BSR and Truncated BSR) that can only report BSRs for one logical channel group, as follows:

LCG ID

Buffer Size

wherein, the LCG ID is a logical channel group Identifier (ID), and Buffer Size is used to carry a BSR of a logical channel group corresponding to the LCGID.

2. The other is a long BSR format.

Which includes Buffer Size for 4 logical channel groups, for carrying BSRs for 4 logical channel groups.

When there are more logical channel groups, for example, 8, then the following problems may occur if reporting is performed according to the existing BSR format:

1. if the terminal has less than 8 logical channel groups and BSR needs to be reported, the BSR of the LCG may cause resource waste if reported.

2. If the padding bits of the medium access control (Media Access Control, MAC) protocol data unit (Protocol Data Unit, PDU) are sufficient to transmit BSR of 3 LCGs, full utilization of resources cannot be achieved with the existing short BSR format.

In view of this, the embodiments of the present application provide a method for transmitting information, which can flexibly adjust the reporting format of the BSR of the logical channel group.

Fig. 2 is a schematic flow chart of a method 200 for transmitting information according to an embodiment of the present application, where the method 200 may be performed by a terminal device in the wireless communication system shown in fig. 1, and as shown in fig. 2, the method 200 includes:

s210, the terminal equipment determines a target BSR format in at least two buffer status report BSR formats according to a first logic channel group set of data to be transmitted in a plurality of logic channel groups;

and S220, reporting the BSR of part or all of the logical channel groups in the first logical channel group set by using the target BSR format.

It should be noted that the number of the plurality of logical channel groups may be 8, more, or less than 8, for example, 4 or 6, which are determined in the latest NR discussion, and the number of the plurality of logical channel groups in the embodiment of the present application is not limited.

It should be understood that the at least two BSR formats may include two BSR formats, or may include more than 2 BSR formats, for example, if the number of logical channel groups is 4, the at least two BSR formats may include two BSR formats, one being a BSR for reporting 2 logical channel groups, another being a BSR for reporting 4 logical channel groups, or may also employ two BSR formats of the prior art; or when the number of the plurality of logical channel groups is 4, four BSR formats may be included, which correspond to BSR formats used when BSRs of 1 to 4 logical channel groups need to be reported, respectively.

For another example, if the number of the plurality of logical channel groups is 8, the at least two BSR formats may include three BSR formats, which respectively correspond to BSRs capable of reporting 2, 4 and 8 logical channel groups, or may also include 8 BSR formats, which respectively correspond to BSR formats used when BSRs of 1 to 8 logical channel groups need to be reported.

Preferably, the determining the at least two BSR formats may specifically include several BSR formats according to the number of the plurality of logical channel groups, for example, if the number of the plurality of logical channel groups is 4, 2 BSR formats may be corresponding to the BSR of 2 and 4 logical channel groups, respectively, or if the number of the plurality of logical channel groups is 8, 3 BSR formats may be corresponding to the BSR of 2, 4 and 8 logical channel groups, respectively, or if the number of the plurality of logical channel groups is 10, 4 BSR formats may be corresponding to the BSR of 2, 4, 8 and 16 logical channel groups, respectively, that is, if the number of the plurality of logical channel groups is recorded as N, the number of BSR formats included in the at least two BSR formats may be K, N and K may satisfy the following relationship: 2 ^K ≥N。

In the following, the embodiments of the present application will be described by taking the example that the plurality of logical channel groups includes 8 logical channel groups, but the embodiments of the present application should not be construed as being limited in any way.

Alternatively, as an embodiment, S210 may include:

That is, the terminal device may determine which BSR format is adopted according to the number of logical channel groups included in the first logical channel group set, specifically, the number of BSRs that the target BSR format can report is determined to be greater than or equal to the number of logical channel groups in the first logical channel group set, that is, the number of Buffer Size included in the target BSR format is greater than the number of logical channel groups included in the first logical channel group.

For example, the at least two BSR formats include format 1 and format 2, where format 1 can report BSR of 2 logical channel groups, format 2 can report BSR of 4 logical channel groups, and if the first logical channel group set includes 3 logical channel groups, the terminal device may determine that the target BSR format is format 2, or if the first logical channel group set includes 2 logical channel groups, the terminal device may determine that the target BSR format is format 1.

In another implementation, S210 may further include:

In the first correspondence, different logical channel number ranges correspond to corresponding BSR formats, for example, the first correspondence may be as shown in table 1:

TABLE 1

Range of logical channel number	BSR format
		1～2	BSR format1
3～4	BSR format 2
		5～8	BSR format 3

Wherein, BSR format 1 can report BSR of 2 logical channel groups, BSR format 2 can report BSR of 4 logical channel groups, and BSR format 3 can report BSR of 8 logical channel groups.

Then, the terminal device may determine which BSR format is to be used according to the number of logical channel groups included in the first logical channel group set in combination with the first correspondence, for example, if the number of logical channel groups included in the first logical channel group set is 3, BSR format 2 may be used, or if the number of logical channel groups included in the first logical channel group set is 6, BSR format 3 may be determined to be used.

Optionally, if the terminal device reports BSRs of all logical channel groups, the BSR format may not include identification information of the logical channels, and the terminal device only needs to fill BSRs of each logical channel group in sequence according to the identifications of the logical channels, for example, the order of LCG IDs, that is, the BSR of each logical channel group corresponds to a corresponding Buffer Size field in the target BSR format, and the network device may obtain BSRs of the corresponding logical channel groups from the corresponding Buffer Size field.

Or if the terminal device only reports BSR of a part of the logical channel groups, the target BAR format needs to include the identification information of the reported logical channel groups, for example, LCG ID, which is used to indicate the logical channel group corresponding to each BSR that is reported.

For example, when the plurality of logical channel groups is 8 logical channel groups, the LCG ID is increased to 3 bits to distinguish the 8 logical channel groups, and in a future NR system, the granularity of reporting the BSR may be reduced, which means that the Buffer Size corresponding to each logical channel group is also increased, and the above three BSR formats are described by taking the Buffer Size as 9 bits (bit) as an example.

1. BSR format 1:

/>

the terminal device may use the BSR format 1 when 1 or 2 logical channel groups need to report BSR, or the padding bits of the MAC PDU are only enough to send BSR of 2 logical channel groups.

The Buffer Size is used for filling BSR of the logical channel groups, and since only BSR of a part of logical channel groups in the 8 logical channel groups is reported, the BSR format needs to include an LCD ID corresponding to each BSR, which logical channel group the reported BSR corresponds to.

It should be noted that, in this embodiment, each time the BSR format behaves as 8 bits, the lcd ID is 3 bits, and the buffer Size is 9 bits, for alignment, in some cases, the BSR of the same logical channel group may be divided into two rows for representation.

It should be understood that bs#x and Buffer size#x each represent Buffer size#x, or bs#x may be regarded as shorthand for Buffer size#x.

2. BSR format 2:

the terminal device may use the BSR format 2 when there are 3 or 4 logical channels to report the BSR, or the padding bits of the MAC PDU are only enough to send the BSR of the 4 logical channel groups.

Similar to BSR format 1, since only BSR of a part of the 8 logical channel groups is reported, the BSR format needs to include an LCD ID corresponding to each BSR to indicate which logical channel group the reported BSR corresponds to.

3. BSR format 3:

the terminal device may adopt the BSR format 3 when the number of logical channel groups on which BSR needs to be reported is greater than 4, or when padding bits of the MAC PDU are sufficient to transmit BSR of 8 logical channel groups.

It should be understood that when the number of logical channel groups that actually need to report BSR is less than 8, for example, only 6 BSR of logical channel groups need to be reported, the terminal device may fill the remaining two Buffer sizes with invalid bits, or 0.

As still another embodiment, S210 may further include:

For example, when the size of the uplink grant resource is sufficient to transmit the BSR of each logical channel group in the first logical channel group set, the terminal device may determine that the number of logical channel groups that can be reported by the target BSR format is greater than or equal to the BSR of each logical channel group in the first logical channel group; or if the size of the uplink grant resource is not enough to transmit the BSR of each logical channel group in the first logical channel group, the terminal device may report only the BSR of a part of the logical channel groups in the first logical channel group set.

For example, the first logical channel group set includes 3 logical channel groups, and the size of the uplink grant resource is sufficient to transmit BSRs of 4 logical channel groups, then the terminal device may determine to report BSRs of each logical channel group in BSR format 2; or if the size of the uplink grant resource is enough to transmit BSRs of only 2 logical channel groups, the terminal device may determine to report BSRs of two logical channel groups in the first logical channel group set in BSR format 1.

Further, the determining, according to the first logical channel group set and the size of the uplink grant resource, a target BSR format from at least two buffer status report BSR formats includes:

In order to improve the resource utilization, the terminal device may transmit BSRs to be reported in padding (padding) bits of the MAC PDU, which are generally referred to as padding BSRs, so that the terminal device may determine which BSR format to use according to the first logical channel group set and the size of the padding bits of the MAC PDU.

For example, the resources required for transmitting the BSR of each logical channel group in the first set of logical channel groups are larger than the size of the padding bit of the MAC PDU, i.e. the size of the padding bit of the MAC PDU is insufficient for transmitting the BSR of each logical channel group, then the terminal device may determine how many BSRs of logical channel groups the padding bit of the MAC PDU can transmit, e.g. the first set of logical channel groups includes 3 logical channel groups, the padding bit of the MAC PDU is sufficient for transmitting the BSR of 2 logical channel groups, then the terminal device may determine that the number of BSRs that can be reported by the target transport format is 2.

Or if the resources required for transmitting the BSR of each logical channel group in the first set of logical channel groups are smaller than the size of the padding bit of the MAC PDU, i.e., the size of the padding bit of the MAC PDU is sufficient to transmit the BSR of each logical channel group, the BSR of each logical channel group may be transmitted using the padding bit of the MAC PDU.

As a specific embodiment, the determining the target BSR format in the at least two buffer status report BSR formats according to the first logical channel group set and the size of the padding bits of the medium access control MAC protocol data unit PDU in the uplink grant resource may include:

If the first resource required for reporting the BSR of each logical channel group in the first logical channel group set is greater than or equal to the size of the padding bit of the MAC PDU, determining a second BSR format as the target BSR format in the at least two BSR formats, wherein the resource required for reporting the BSR in the second BSR format is less than or equal to the size of the padding bit of the MAC PDU; or (b)

For example, if the at least two BSR formats include BSR format 1, BSR format 2, and BSR format 3, BSR format 1, BSR format 2, and BSR format 3 may correspond to BSR format 1, BSR format 2, and BSR format 3 in the foregoing embodiments. If the number of logical channel groups to report the BSR is 4, the padding bit of the MAC PDU is sufficient to transmit the BSR of 3 logical channel groups, that is, the size of the padding bit of the MAC PDU is smaller than the resources required for reporting the BSR, then the terminal device may determine to use BSR format 1, that is, report only the BSR of two logical channel groups in the first logical channel group set.

For another example, if the number of logical channel groups for reporting BSR is 5, the padding bit of the MAC PDU is sufficient to transmit BSR of 6 logical channel groups, that is, the size of the padding bit of the MAC PDU is larger than the resources required for reporting BSR, but BSR of 5 logical channels needs to adopt BSR format 3, and the size of the padding bit of the MAC PDU is insufficient to transmit BSR of 8 logical channel groups, in this case, the terminal device may determine that BSR format 2 is adopted, that is, BSR of only 4 logical channel groups is reported.

That is, in the BSR format selection, not only whether the size of padding bits of the MAC PDU is sufficient to transmit the BSR of each logical channel group in the first logical channel group set, but also the size of resources required for the BSR formats included in at least two BSR formats needs to be considered, and in combination of the above three factors, the terminal device may finally be in a suitable target BSR format.

As an implementation manner, the plurality of logical channel groups includes N logical channel groups, where N is an integer greater than 1, and the at least two BSR formats include N BSR formats, where the N BSR formats are respectively used to report BSRs of different numbers of logical channel groups in the N logical channel groups, in this case, S210 may further include:

And determining a BSR format corresponding to the number of the logical channel groups in the first logical channel group set as the target BSR format.

For example, for 8 logical channel groups, the at least two BSR formats may include 8 BSR formats, each for transmitting BSRs of 1 to 8 logical channel groups, i.e., each format corresponds to a corresponding number of logical channel groups, transmitting BSRs of different numbers of logical channel groups, a corresponding BSR format may be used, and if the first logical channel group set includes 3 logical channel groups, a number 3 corresponding BSR format may be employed, in which three Buffer Size fields may be included, and 3 LCGID fields for carrying BSR and LCGID information of three logical channel groups, respectively.

Optionally, as an embodiment, the method 200 may further include:

That is, the terminal device may notify the network device that the BSR is in a BSR format, for example, the terminal device may send a MAC PDU to the network device, where the indication information is carried in a sub-header (subheader) of the MAC PDU. Specifically, the indication information may be carried in an LCID field in a packet header of the MAC PDU, for example, the terminal device may carry the indication information through a reserved (reserved) field in an existing LCID field, or may also add a field in an LCID field for carrying the indication information.

Or, the terminal device may carry the indication information through other existing messages or information, so as to notify the network device of the target BSR format adopted by the BSR of the device, and the specific notification mode of the indication information is not limited in this embodiment of the present application.
