Description

Method and device for reporting cache status and allocating resources

This application claims the priority of the Chinese Patent Application filed on September 25, 2017, the Chinese Patent Office, Application No. 201710874651.7, the application of which is entitled "A method and a device for reporting the buffering status and allocating resources", the entire contents of which are incorporated by reference. Combined in this application.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for reporting a buffer status and allocating resources.

Background technique

Long Term Evolution (LTE) Media Access Control (MAC) Protocol Data Unit (PDU) format is shown in Figure 1. Wherein, "R" indicates a reserved bit; "F2" and "F" jointly indicate the length of the L domain, if the MAC sub-head corresponds to a MAC service data unit (SDU) or a MAC control unit (Control Element, The length of CE) is greater than 32767 bytes, F2=1, otherwise F2=0; “E” is used to indicate whether the subsequent MAC subheader, if the subsequent MAC subheader, E=1, otherwise E=0; “LCID” is The logical channel group number, the logical channel group corresponding to each bearer RB has a logical channel group number LCID, and each MAC CE also corresponds to one LCID; "L" indicates the length of the corresponding MAC SDU or MAC CE, and the unit is byte.

The LTE MAC CE may be of a variable length or a fixed length. If the length is longer, the MAC subheader carries the L field. If the length is fixed, the MAC subheader does not have the L field.

There are two types of BSR MAC CEs for the BSR (Buffer Status Report) in the LTE: the BSR MAC CE that reports only one logical channel group and the BSR MAC CE that reports all four logical channel groups.

In the 5G NR (new air interface), the number of logical channel groups is increased to eight, and the logical channel group (LCG) ID needs to occupy 3 bits. If a short BSR of 1 byte is supported, the Buffer Size field is only 5 bits. However, the service rate and transmission rate supported by the 5G are greatly improved, and the maximum value of the buffer status report is greatly improved. If the 5-bit Buffer Size field length is used uniformly, the buffer status cannot be accurately represented, so that the base station cannot accurately schedule the terminal data, resulting in insufficient resource allocation. Or waste of resources.

In summary, the current Buffer Size field length cannot accurately represent the buffer status, so that the base station cannot accurately schedule the terminal data, resulting in insufficient resource allocation or waste of resources.

Detailed ways

The present invention will be further described in detail with reference to the accompanying drawings, in which . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 2, the system for allocating resources according to an embodiment of the present invention includes:

The terminal 10 is configured to determine a used BSR MAC CE format according to the number of logical channel groups that need to report the buffer status, and generate a BSR MAC according to the determined BSR MAC CE format and the number of bits occupied by the buffer sequence number in the BSR MAC CE format. The CE sends the generated BSR MAC CE to the network side device.

The network side device 20 is configured to receive, by the terminal, a BSR MAC CE generated according to the determined BSR MAC CE format and the number of bits occupied by the buffer sequence number in the BSR MAC CE format, and determine, according to the BSR table, a cache corresponding to the cache serial number in the BSR MAC CE. The amount of data; allocating uplink resources to the terminal according to the determined amount of cached data.

In the embodiment of the present invention, the terminal generates a BSR MAC CE according to the used BSR MAC CE format determined by the number of logical channel groups that need to be reported in the buffer state, and the number of bits occupied by the buffer sequence number in the BSR MAC CE format, and generates the BSR. The MAC CE is reported to the network side device. The network side device determines, according to the BSR table, the amount of buffered data corresponding to the buffer sequence number in the BSR MAC CE, and allocates the uplink resource to the terminal according to the determined amount of the buffered data. The terminal can determine the BSR MAC CE format to be used according to the number of logical channel groups that need to report the buffer status, and generate a BSR MAC CE according to the number of bits occupied by the buffer sequence number in the BSR MAC CE format, and can select different numbers for different logical channel groups. The BSR MAC CE format enables more accurate scheduling of terminal data, reducing the number of times the resource allocation is insufficient or the resource is wasted.

According to the embodiment of the present invention, the first BSR MAC CE format capable of reporting the buffer status of multiple logical channel groups or the first BSR capable of reporting the buffer status of one logical channel group may be selected according to the number of logical channel groups that need to report the buffer status. MAC CE format.

The terminal stores the first BSR MAC CE format and the second BSR MAC CE format, and each BSR MAC CE format corresponds to a BSR table.

It should be noted that the BSR table records the correspondence between the cache sequence number and the cache data amount range. That is, the BSR table is only a form that displays the correspondence between the cache sequence number and the cache data amount range, and can also be adopted as needed. Other forms of presentation, such as databases, formulas, etc. Different presentations are simply substitutions of tables that fall within the scope of equivalent technology.

One possible first BSR MAC CE format is shown in FIG. 3A, and one possible second BSR MAC CE format is shown in FIG. 3B.

The length of the Buffer Size field in Figure 3A can be 5 bits or other values.

The length of the Buffer Size field in Figure 3B is 8 bit. The length of the Buffer Size field in the second BSR MAC CE format may also be other values, such as 7 bits.

In FIG. 3B, the first byte is used to indicate which logical channel groups need to be reported and buffered, and then the cache is sequentially reported in the order indicated in the bitmap of the first byte. The BSR MAC CE in this format is variable length. You can report the cache of 1 to 8 logical channel groups as needed.

For example, if the logical channel groups LCG1, 3, and 5 have data buffers to be reported, the BSR MAC CE is 4 bytes in length except for the MAC sub-header, and the first byte is a bitmap indication. For this example, it is set to 01010100 (that is, the first 1/3/5). The logical channel group is set to 1), and the 2nd, 3rd, and 4th bytes respectively indicate the data buffer amounts of the logical channel groups 1, 3, and 5.

In an implementation, the BSR table corresponding to the second BSR MAC CE format stored by the terminal may be different from the table corresponding to the first BSR MAC CE format;

The BSR table corresponding to the second BSR MAC CE format is a BSR table corresponding to the first BSR MAC CE format.

The length of the Buffer Size field in the first BSR MAC CE format is greater than the length of the Buffer Size field in the second BSR MAC CE format.

The table corresponding to the first BSR MAC CE format is generated by exponential distribution according to the length of the Buffer Size field in the first BSR MAC CE format.

If the BSR table corresponding to the second BSR MAC CE format is a separate table (that is, the BSR table corresponding to the first BSR MAC CE format is not multiplexed), the BSR table corresponding to the second BSR MAC CE format is based on the second BSR MAC. The length of the Buffer Size field in the CE format is generated by exponential distribution.

The following is an example of the length of the Buffer Size field in the first BSR MAC CE format. The other values are, for example, 7 bits, which are similar to the 8 bits, and are not described here.

The length of the 8bit Buffer Size generates a single BSR table, which indicates that the buffer data amount interval is 256 (that is, 2^8. 2^X indicates 2 ^x , and the subsequent descriptions are not explained).

For convenience of explanation, the BSR table corresponding to the 8-bit BS is constructed by taking the same maximum buffer value Bmax=3000000byte as LTE as follows. It should be noted that Table 1 is only an example. The maximum buffer value Bmax of the actual 5G NR is much larger than 3000000 bytes, and the divided interval can also be set according to needs.

Table 1 Example of BSR table for 8bit BS size

The following is an example of the length of the Buffer Size field in the first BSR MAC CE format. The other values are similar to those of the 5 bit, and are not described here.

The 5bit Buffer Size length generates a single BSR table, and the indicated buffer data amount interval is 32 (that is, 2^5).

For convenience of explanation, the BSR table corresponding to the 8-bit BS is constructed by taking the same maximum cache value Bmax=3000000byte as LTE as follows. It should be noted that Table 2 is only an example. The maximum buffer value Bmax of the actual 5G NR is much larger than 3000000 bytes, and the divided interval can also be set according to the needs.

Index	Buffer Size(BS)value[bytes]	Index	Buffer Size(BS)value[bytes]
1	BS=0	17	4407<BS<=6808

16	2853<BS<=4407	32	BS>3000000

Comparing Table 1 and Table 2, it is clear that under the same maximum and minimum values, the larger the number of bits, the more accurate the indication range. The smaller the number of indicated bits, the larger the indication range for the amount of large data when the index value is high. However, since the BSR table is generated by using the exponential distribution, the amount of cached data when the amount of small data is relatively accurate.

In the implementation, both the terminal and the base station need to distinguish between the BSR of the single logical channel group or the BSR of the multiple logical channel groups, which are distinguished by different LCIDs. For example, LCID1 indicates that a single logical channel group is reported, and LCID2 indicates that the report is reported. Is a group of multiple logical channels.

Based on the above, the embodiment of the present invention provides two modes: mode 1: the terminal adopts one table, that is, the BSR table corresponding to the second BSR MAC CE is a BSR table corresponding to the first BSR MAC CE format; Two: The terminal adopts two tables, that is, the table of the BSR corresponding to the second BSR MAC CE is an independent table.

The following describes the status of reporting multiple logical channel groups and reporting the status of one logical channel group as an example.

Case 1: Reporting multiple logical channel group buffer states.

Specifically, if the number of logical channel groups that need to be reported in the buffer state is multiple, the terminal uses a first BSR MAC CE format that can report a plurality of logical channel group buffer states.

The table of the BSR corresponding to the second BSR MAC CE in the terminal is to multiplex the BSR table corresponding to the first BSR MAC CE format, or the table of the BSR corresponding to the second BSR MAC CE in the terminal is an independent table, and the report buffer needs to be reported. When the number of logical channel groups of the state is plural, the terminal uses a first BSR MAC CE format capable of reporting a plurality of logical channel group buffer states.

Optionally, when the terminal generates the BSR MAC CE, determining, according to the BSR table corresponding to the first BSR MAC CE format, a cache sequence number corresponding to the buffered data volume of each logical channel group;

The terminal places the determined cache sequence number in a location corresponding to the first BSR MAC CE format.

Correspondingly, the network side device determines, according to the BSR table corresponding to the first BSR MAC CE format, the amount of cache data corresponding to the cache sequence number in the BSR MAC CE.

For example, there are two logical channel groups of logical channel group A and logical channel group B. The amount of buffered data of logical channel group A is 6523 bits, and the amount of buffered data of logical channel group A is 329 bits. Taking Table 1 as an example, after the terminal looks up the table, the buffer number corresponding to the cached data volume 6523 bit of the logical channel group A is 133; after the terminal looks up the table, the cache serial number corresponding to the buffered data volume 329 bit of the logical channel group B is 73. After that, the terminal places 133 and 73 respectively in positions corresponding to the first BSR MAC CE format;

After receiving the BSR MAC CE in the format of the first BSR MAC CE, the network side device knows that the terminal reports the buffer status of multiple logical channel groups. After determining the cache identifiers 133 and 73, the logical channel group A can be known according to Table 1. The amount of cached data is between 6522 and 6855, and the number of buffers for logical channel group B is between 328 and 345.

Case 2: Reporting a logical channel group buffer status.

For reporting the status of a logical channel group buffer, the processing procedure of the terminal using one table and the terminal using two tables is different, which are respectively introduced below.

Method 1: The terminal uses one table.

For the terminal to use one table, the terminal may be configured to use a second BSR MAC CE format that can report the buffer status of one logical channel group. The terminal may also be configured to determine the used BSR according to the buffered data volume of the logical channel group. The MAC CE format is described below.

1. The terminal selects a second BSR MAC CE format that can report the buffer status of one logical channel group.

In this manner, regardless of the amount of buffered data of the logical channel group reported by the terminal, only the second BSR MAC CE format is selected as long as the buffer state of one logical channel group is reported.

Here, the reporting of a logical channel group buffer state may be that one logical channel group needs to be reported; or the terminal may send a padding BSR after transmitting the uplink transmission according to the obtained uplink resource, but the remaining resources are only enough to send one logical channel group. BSR.

Optionally, when the terminal generates the BSR MAC CE, according to the number of bits occupied by the buffer sequence number and the buffered data volume of the logical channel group in the second BSR MAC CE format, the terminal corresponds to the first BSR MAC CE format. Determining, in the BSR table, a cache sequence number corresponding to the amount of buffered data of the logical channel group;

The terminal places the determined cache sequence number in a location corresponding to the second BSR MAC CE format.

The second BSR MAC CE format can only be multiplexed in the table corresponding to the first BSR MAC CE format, because the number of bits in the Buffer Size field of the second BSR MAC CE format is smaller than the number of bits in the Buffer Size field of the first BSR MAC CE format. Part of the content.

For example, if the Buffer Size field of the second BSR MAC CE format is 5 bits, and the Buffer Size field of the first BSR MAC CE format is 8 bits, the second BSR MAC CE format can only multiplex 32 cache numbers in the second BSR MAC CE format. .

Based on this, the embodiment of the present invention provides a feasible manner: multiplexing the first (2^X-1) cache serial numbers in the second BSR MAC CE format, if the front (2^X-1) cache serial numbers It is not possible to indicate that the cache sequence number can be set to a maximum value, indicating that the amount of cache data has exceeded the amount of cache data represented by the (2^X-1) cache sequence numbers in the BSR table corresponding to the first BSR MAC CE format. Where X is the number of bits occupied by the buffer sequence number in the second BSR MAC CE format.

Specifically, if the first (2^X-1) cache numbers in the BSR table corresponding to the first BSR MAC CE format can represent the buffered data volume of the logical channel group, the terminal is configured according to the first BSR. a BSR table corresponding to the MAC CE format, determining a cache serial number corresponding to the buffered data volume of the logical channel group; or

If the first (2^X-1) cache sequence numbers in the BSR table corresponding to the first BSR MAC CE format cannot indicate the buffered data volume of the logical channel group, the terminal sets the cache sequence number to a maximum value, indicating The amount of cached data exceeds the amount of cached data represented by the (2^X-1) cache sequence numbers in the BSR table corresponding to the first BSR MAC CE format.

Correspondingly, if the cache sequence number in the BSR MAC CE is the first (2^X-1) cache sequence numbers in the BSR table corresponding to the first BSR MAC CE format, the network side device is configured according to the first The BSR table corresponding to the BSR MAC CE format determines the amount of cached data corresponding to the cache sequence number in the BSR MAC CE; or

If the number of the buffer in the BSR MAC CE is the maximum value, the network side device determines that the buffered data volume of the terminal exceeds the (2^X-1) cache in the BSR table corresponding to the BSR MAC CE format. The amount of cached data represented by the sequence number.

The Buffer Size field in the second BSR MAC CE format is 5 bits, and the Buffer Size field in the first BSR MAC CE format is 8 bits.

If the amount of buffered data of the logical channel group that the terminal needs to report can be represented by the first 31 cache numbers in Table 1, for example, the buffered data volume of the logical channel group is 22, the lookup table 1 can determine that the corresponding cache serial number is 17. 17 can be represented by 5 bits, so the cache identifier corresponding to the amount of cached data of the logical channel group that needs to be reported is 17;

Correspondingly, after receiving the BSR MAC CE in the format of the second BSR MAC CE, the network side device knows that the terminal reports the buffer status of a logical channel group. After determining that the cache identifier is 17, it can check Table 1 to determine the logical channel group. The amount of cached data is 22.

If the amount of cached data of the logical channel group that the terminal needs to report cannot be represented by the first 31 cache numbers in Table 1, for example, the cached data volume of the logical channel group is 46, the lookup table 1 can determine that the corresponding cache serial number is 33, which exceeds 31. Determine a cache identifier corresponding to the amount of buffered data of the logical channel group to be reported as a maximum value represented by 5 bits, and 11111 is 32.

Correspondingly, after receiving the BSR MAC CE in the format of the second BSR MAC CE, the network side device knows that the terminal reports the buffer status of a logical channel group. After determining that the cache identifier is 32, the amount of the buffered data of the logical channel group can be determined. More than 43.

2. The terminal determines the BSR MAC CE format to be used according to the buffered data volume of the logical channel group.

The second BSR MAC CE format can only be multiplexed in the table corresponding to the first BSR MAC CE format, because the number of bits in the Buffer Size field of the second BSR MAC CE format is smaller than the number of bits in the Buffer Size field of the first BSR MAC CE format. Part of the content.

For example, if the Buffer Size field of the second BSR MAC CE format is 5 bits, and the Buffer Size field of the first BSR MAC CE format is 8 bits, the second BSR MAC CE format can only multiplex 32 cache numbers in the second BSR MAC CE format. .

Based on this, the embodiment of the present invention provides a feasible manner: multiplexing the first (2^X) cache serial numbers in the second BSR MAC CE format, if the previous (2^X) cache serial numbers cannot be represented, The first BSR MAC CE format is selected (that is, if the first (2^X) cache sequence numbers cannot be represented, the first BSR MAC CE format is selected even if only one logical channel group buffer state needs to be reported.

Specifically, the first 2×X cache numbers of the BSR table corresponding to the first BSR MAC CE format cannot represent the buffered data volume of the logical channel group, and the terminal uses the buffer status that can report multiple logical channel groups. a first BSR MAC CE format, where X is the number of bits occupied by the buffer sequence number in the second BSR MAC CE format; or

If the BSR table corresponding to the second BSR MAC CE of the terminal is a BSR table corresponding to the first BSR MAC CE format, and the first 2^X cache numbers of the BSR table corresponding to the first BSR MAC CE format The second BSR MAC CE format capable of reporting the buffer status of one logical channel group, where X is the number of bits occupied by the buffer sequence number in the second BSR MAC CE format, can be used to indicate the amount of buffered data of the logical channel group. .

Optionally, the terminal determines, according to the BSR table corresponding to the first BSR MAC CE format, a cache sequence number corresponding to the buffered data volume of the logical channel group, and places the determined cache sequence number on the first BSR MAC. The CE format corresponds to the location.

Correspondingly, the network side device determines, according to the BSR table corresponding to the first BSR MAC CE format, the amount of cache data corresponding to the cache sequence number in the BSR MAC CE.

The Buffer Size field in the second BSR MAC CE format is 5 bits, and the Buffer Size field in the first BSR MAC CE format is 8 bits.

If the amount of buffered data of the logical channel group that the terminal needs to report can be represented by the first 32 cache numbers in Table 1, for example, the buffered data volume of the logical channel group is 22, the lookup table 1 can determine that the corresponding cache serial number is 17. 17 can be represented by 5 bits, so the cache identifier corresponding to the amount of cached data of the logical channel group that needs to be reported is 17;

Correspondingly, after receiving the BSR MAC CE in the format of the second BSR MAC CE, the network side device knows that the terminal reports the buffer status of a logical channel group. After determining that the cache identifier is 17, it can check Table 1 to determine the logical channel group. The amount of cached data is 22.

If the amount of cached data of the logical channel group that the terminal needs to report cannot be represented by the first 32 cache numbers in Table 1, for example, the buffered data volume of the logical channel group is 46, the lookup table 1 can determine that the corresponding cache serial number is 33, which exceeds 32. At this time, the terminal chooses to report in the format of the first BSR MAC CE, and the corresponding cache serial number is 33.

Correspondingly, the network side device receives the BSR MAC CE format as the first BSR MAC CE. After determining that the cache identifier is 33, the lookup table 1 can determine that the cached data volume of the logical channel group is 44 or 45.

Method 2: The terminal uses two tables.

For the terminal to adopt two tables, the terminal may determine, according to the BSR table corresponding to the second BSR MAC CE format, a cache sequence number corresponding to the buffered data volume of the logical channel group.

The terminal places the determined cache sequence number in a location corresponding to the second BSR MAC CE format.

Correspondingly, after the received BSR MAC CE is in the second BSR MAC CE format, the network side device determines, according to the BSR table corresponding to the second BSR MAC CE format, the cache data corresponding to the cache sequence number in the BSR MAC CE. the amount.

The Buffer Size field in the second BSR MAC CE format is 5 bits, and the Buffer Size field in the first BSR MAC CE format is 8 bits.

If the amount of buffered data of the logical channel group that the terminal needs to report is 22, the lookup table 2 can determine that the corresponding cache serial number is 3.

Correspondingly, after receiving the BSR MAC CE in the format of the second BSR MAC CE, the network side device knows that the terminal reports the buffer status of a logical channel group.
