Technical field
[0001]
The present invention relates to the field of communications, and in particular, to a data indicating method, device, and communication system.
Background technique
[0002]
In a Long Term Evolution (LTE) system, resources for transmitting uplink data are obtained according to a buffer status report (Buffer Status Report (BSR)). The buffer status report is used to provide user equipment (user equipment, UE) to the serving base station. How much upstream data needs to be sent.
[0003]
It should be noted that the above description of the technical background is merely for the convenience of a clear and complete description of the technical solution of the present invention, and for the understanding of those skilled in the art. The above technical solutions should not be considered to be well known to those skilled in the art just because these solutions are explained in the background section of the present invention.
[0004]
Summary of the invention
[0005]
In the LTE system, BSR has two data formats, namely short BSR and long BSR. Among them, a 2-bit field is required in the format of the short BSR to indicate the identifier of the logical channel group corresponding to the buffer status (Logical channel group). identification, LCG ID), and also requires a buffer size field (Buffer Size) to specifically indicate the value range of the buffer size in the logical channel group; the value of the LCG ID is not included in the long BSR format, but includes all logical channel groups. The value range of the cache size.
[0006]
In future wireless communication systems, such as 5G and New Radio (NR) systems, the buffer status report (Buffer Status Report, BSR) needs to include at least two formats. One is a short buffer status report (short BSR), and the other is a variable length buffer status report (Variable BSR).
[0007]
Considering that in the future communication system, the number of logical channel groups will increase, so the original LCG ID field needs to be increased accordingly. In this way, the data format of the cache status report cannot meet the byte alignment rules, and its cache size field can no longer be used. 6-bit representation in the LTE system.
[0008]
In addition, due to the introduction of the variable-length BSR format, the result of the MAC layer logical channel data multiplexing may affect the length of the BSR (the logical channel group whose buffer status is empty after data multiplexing does not need to report the buffer status), and then affect The size of the currently available physical resources requires further adjustment of the logical channel data multiplexing, which may once again affect the length of the BSR. Such an operation will increase the processing complexity of the sender, thereby increasing the processing delay.
[0009]
Embodiments of the present invention provide a data indicating method, a device thereof, and a communication system. By including at least one buffer size information in a cache status report, a data format of a short BSR can satisfy a byte alignment rule.

The embodiments of the present invention will be described below with reference to the drawings.
[0055]
Example 1
[0056]
This embodiment 1 proposes a data indicating method. FIG. 1 is a schematic diagram of the data indicating method of this embodiment 1. As shown in FIG. 1, the method includes:
[0057]
Step 101: A buffer status report is sent to the network side. The buffer status report includes at least one buffer size information, and the buffer size information indicates a buffer size corresponding to a logical channel or a logical channel group.
[0058]
In this embodiment, when constructing a media access control layer protocol data unit (MAC PDU), the buffer status report may be encapsulated in a MAC PDU control information unit (control element) and sent to the network side, where the MAC PDU is An 8-bit integer multiple bit string.
[0059]
In this embodiment, the buffer status report carries BSR information of one or more logical channel groups (LCGs), wherein the buffer status report is expressed using a first predetermined number of N bytes (each byte). Corresponding to 8 bits, the format of the buffer status report is a short buffer status report.
[0060]
In this embodiment, since it is necessary to determine the logical channel or logical channel group corresponding to the buffer size indicated by the buffer size information included in the cache status report, the cache status report also includes the identifier of the logical channel or logical channel group.
[0061]
In this embodiment, the identifier of the logical channel or logical channel group is a second predetermined number X bit field, and the buffer size information corresponding to the logical channel or logical channel group is a third predetermined number Y bit field.
[0062]
In this embodiment, each value of the second predetermined number of bit fields corresponds to an identifier of a logical channel or a logical channel group, and the second predetermined number may be determined according to the number of logical channels or logical channel groups, such as a logical channel. When the number of groups is 5 to 8, the second predetermined number is 3. For example, "000" indicates that the logical channel or logical channel group ID is 0, and "001" indicates that the logical channel or logical channel group ID is 1, " “010” indicates that the identification of the logical channel or logical channel group is 2, ..., and so on. The above is only an exemplary description, and the second predetermined number may also take other values.
[0063]
In this embodiment, in order to satisfy the byte alignment rule, the sum of the second predetermined number and the third predetermined number is equal to an integer multiple of 8 bits. Therefore, the third predetermined number may be determined according to the second predetermined number to ensure short The BSR data format length is an integer multiple of 8 bits.
[0064]
For example, the buffer size information is a field with a third predetermined number Y of 5 bits, or a field smaller than 5 bits or larger than 6 bits. Each value of this field corresponds to a value range of the cache size.
[0065]
For example, the format of the buffer status report may be N bytes. When the identifier of the logical channel group is represented by an X-bit field, the buffer size information is a Y-bit field, where 8N = X + Y, where N , X, Y are positive integers greater than 1.
[0066]
For example, when N = 1, X = 3, Y = 5, N = 2, and X = 6, Y = 10, and no further examples are given here.
[0067]
The following uses Y = 5 as an example to describe the buffer size value range corresponding to each value, which is not limited in this embodiment.
[0068]
In this embodiment, since the buffer size information is a 5-bit field, and its value is 32, each value corresponds to a value range of the buffer size.
[0069]
In one embodiment, the maximum cache size that can be represented by the cache size information is 150k bytes, and the range of cache size values ​​corresponding to each value is shown in Table 1 below:
[0070]
Table 1
[0071]

[0072]
In one embodiment, the maximum cache size that can be represented by the cache size information is 3000k bytes, and the range of cache size values ​​corresponding to each value is shown in Table 2 below:
[0073]
Table 2
[0074]

[0075]
Therefore, in the future communication system, the byte alignment rule can be satisfied, and the short BSR data format length is guaranteed to be an integer multiple of 8 bits.

The BSR contains buffer size information of the P logical channels, and may also include buffer size information of MP logical channel groups whose buffer size is greater than zero, where M, N, and P are integers greater than or equal to zero.
[0130]
For example, before the logical channel data is reused, that is, before the MAC PDU is constructed, the buffer sizes of the logical channel groups LCG1, LCG2, and LCG3 are greater than zero, and the buffer sizes of other logical channel groups are zero. It can be determined that the cache status report contains LCG1, LCG2, and LCG3 cache size information. After the logical channel data is multiplexed, that is, after the MAC PDU has been constructed, all the cached data in LCG2 has been multiplexed, and its cache size is zero. The cache status report can still include the LCG2 cache size information, that is, the cache The status report can include cache size information for LCG1, LCG2, and LCG3.
[0131]
In this embodiment, the buffer size information is a field of a predetermined number of bits, and each value corresponds to a value range of the buffer size.
[0132]
Therefore, the logical channel group whose buffer status is empty after data multiplexing does not need to report the buffer status. In the future communication system, it is possible to reduce the processing complexity and processing delay of the transmitting end.

Example 7
[0149]

[0150]
Step 1101: Receive a variable-length buffer status report sent by a user equipment. The variable-length buffer status report includes a logical channel whose buffer size is greater than zero when the buffer status report is triggered or before logical channel data is reused. The buffer size information of a group; or the buffer size information of a logical channel group containing a buffer size greater than zero before logical channel data multiplexing and a buffer size equal to zero after logical channel data multiplexing.
[0151]
In this embodiment, for the format of the variable-length cache status report, reference may be made to Embodiment 5, and details are not described herein again.
[0152]
In this embodiment, the method may further include:
[0153]
Step 1102: Determine the buffer size corresponding to the logical channel group according to the buffer size information. When it is determined that the buffer size of the logical channel group is equal to zero, determine that there is no data to be sent in the logical channel group; When the size is greater than zero, it is determined that the logical channel group has data to be transmitted.
[0154]
In step 1102, the network side reads the cache size information in the cache cache status report, determines the logical channel group contained therein, and the cache size corresponding to each logical channel group. For example, in determining the cache size of a cache channel group When it is equal to zero, it is determined that there is no data to be sent in the logical channel group; when it is determined that the buffer size of a buffer channel group is greater than zero, it is determined that data is to be sent in the logical channel group.
[0155]
In step 1102, when it is determined that the buffer size of the logical channel group is greater than zero, the method may further include: allocating resources to the user equipment according to the buffer size. For example, a suitable resource may be allocated for the UE to transmit the logical channel group to the UE. Data in the cache, but the specific amount of resources allocated is determined according to the algorithms of devices of different manufacturers, which is not limited in this embodiment.
[0156]
For example, the variable BSR contains the buffer size information of M logical channel groups. Before the logical channel data is reused, that is, before the MAC PDU is constructed, the buffer size of the M logical channel groups is greater than zero. Each side allocates radio resources for M logical channel groups.
[0157]
For example, the variable BSR contains the buffer size information of the P logical channels, where the P logical channels have a buffer size greater than 0 before the MAC PDU is constructed, but after the MAC PDU is constructed, the The buffer size is equal to 0, and the network determines that the P logical channel groups have no data to send. In addition, the variable BSR may also include buffer size information of another Q logical channel groups, where the Q logical channels are being constructed. The buffer size of the logical channel before the MAC PDU is greater than 0. After the completion of the MAC PDU construction, the buffer size of the buffer channel is still greater than 0, so the network side allocates radio resources for the Q logical channel groups, respectively.
[0158]
Therefore, the logical channel group whose buffer status is empty after data multiplexing does not need to report the buffer status. In the future communication system, it is possible to reduce the processing complexity and processing delay of the transmitting end.
