Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a bit compression method and system for UCI reporting.
Background
Reporting feedback information of UCI (Uplink Control information) is supported in a mobile communication system, particularly in a 5G NR system, where the UCI feedback includes feedback for radio Channel quality, such as PMI/CQI/RI/RSRP/LI, and HARQ (Hybrid Automatic Repeat Request) -ACK feedback for downlink PDSCH data scheduling, and the UCI may be fed back on both a PUCCH (Physical Uplink Control Channel) and a PUSCH (Physical Uplink Shared Channel).
On one hand, 5G supports more antennas than 4G, and the more complex codebook Type (e.g., Type II codebook) requires more bits for the feedback of the wireless channel quality; on the other hand, in the HARQ-ACk feedback of 5G, due to more diversified band combinations (such as high and low band combinations), more CA cells (8 cells), joint HARQ codebook feedback and CBG feedback-based techniques, the number of bits for HARQ-ACk feedback is very large, and the 3GPP protocol R15 specifies that the HARQ-ACk feedback capable of supporting 1705 bits at most is provided by the protocol
In general, limited by the effect of the UE-side transmit power, the uplink is often a short board of performance, too many UCI feedback bits occupy a large amount of radio resources, and the performance is often not satisfactory.
Therefore, it is desirable to provide a bit compression method for UCI to solve the above problems.

Specifically, as shown in fig. 2, after entering a UCI compression execution flow, first obtaining a source bit number of an original UCI, determining a maximum preset bit repetition number in the source, that is, a maximum repetition number of 0bit or 1bit, and converting the maximum preset bit repetition number into a 2-ary system, obtaining a maximum bit width length B _ max that can be characterized, setting B to 0, tmp _ B to 2, L to an original source bit number of the UCI, and tmp _ B to an initial used bit width;

the UCI source bit is 111100111000, and if tmp _ B is 2, the segment is decomposed into: 111/1/00/111/000, respectively;
if tmp _ B is 3, the segment is decomposed into: 1111/00/111/000, respectively; and so on in turn.
Further, the length after compression calculated in step 8 is:
tmp_L＝y’*(B+1)+4+11
in the above calculation formula, y' is the number of compressed segments, each compressed segment representing 0/1 that are repeated consecutively; b represents the number of continuous repetitions 0/1 and is represented by a B bit width of a 2-system; a 1 is an 0/1 flag indicating whether the compressed segment repeats a 0or a 1; 4 bits are compression headers for indicating the bit width of the compressed segment, i.e. B +1, and maximally 15 bits.
The UCI compressed segment length indication is set as UCI part 1, fixed to 11 bits and used for indicating the length of the UCI compressed segment, and is set as UCI part2, the UCI part2 is variable length and is obtained by solving the UCI part 1.
And step 9 is carried out after the solution, and whether tmp _ L is smaller than L is judged:
if yes, entering the setting L of step 10 to tmp _ L and B to tmp _ B;
if not, go to step 11, let tmp _ B be tmp _ B +1, and re-execute the above steps.
Entering step 12, representing B +1 by using a 4-bit binary system, and using the B +1 as a head reported by UCI to represent the length of a compressed segment;
in step 13, each compressed segment is made up of two parts:
1)1bit 0/1, indicating 0or 1 in succession;
2) b bit is used to indicate the number of consecutive repetitions.
Based on any of the above embodiments, the method step S3 includes:
obtaining the source bit length of the UCI compressed segment, converting the source bit length into a binary value with a fixed length indicated by the length of the compressed segment, and packaging the binary value into the length indication of the UCI compressed segment;
the UCI compressed segment length indication is used for informing a base station side of the source bit length of the UCI compressed segment;
wherein the UCI compressed segment length indication and the UCI compressed segment employ independent encoding.
Specifically, as shown in fig. 2, in step 14, the header and the compressed segment are combined into a final UCI reporting format, and the reporting format is shown in fig. 3.
In step 15, the UCI part2 source bit length is obtained and converted into an 11bit 2 system, and encapsulated as UCI part 1 for informing the base station side of the length of UCI part 2. The UCI part 1 needs to be coded independently from the UCI part2, and the process is finished in the step 17.
Based on any of the above embodiments, the content of the present invention is described in a specific embodiment, where a specific scenario is that when a base station side indicates that a UE employs a compressed reporting UCI manner, the indication manner includes dynamic DCI indication and direct high-level static configuration.
First, make the following assumption that the UE configures the version static HARQ codebook; CBG transmission is adopted, and the number of CBGs is 8; configuring 8 cells in total; UE configures a PUCCH group to perform HARQ feedback on PDSCHs at 4 occase positions; assuming that the channel quality is excellent, all feedbacks are ACKs; the UE adopts a full scheduling mode, i.e. 8 cells, and all 4 ocseeds will perform PDSCH scheduling, which can be calculated as follows:
the total number of UCI source bits required to be fed back by the UE is 8 × 4 × 8-256 bits
The maximum identical continuous ACK/NACK number is 256 bits, the corresponding binary system is 100,000,000, and the maximum bit width B _ max is 9;
here, it is assumed that the initially used bit width tmp _ B is 2, and the current UCI total length L is 256;
tmp _ B may currently represent consecutive ACKs/NACKs of length not exceeding 3, and the UCI source bit may be divided into 86 segments as follows:
111/111/111/…/111/111/1
each segment needs Tmp _ B, namely 2 bits to represent continuous number and 1bit to indicate ACK/NACK, and 3 bits are needed in total;
the header needs 4 bits, the UCI part 1 (indicating the length of UCI part 2) needs 11 bits, the total required length tmp _ L is calculated to be 11+4+3 × 86 ═ 273 bits, which exceeds the length L, so this compression method is not adopted;
continuously increasing the bit width Tmp _ B1 bit, performing repeated calculation, recording the shortest total length Tmp _ L, and using the shortest total length Tmp _ L as a reporting UCI bit;
it can be found that when Tmp _ B is B _ max and is 9 bits wide, the shortest UCI reporting bit is provided, the total length is 4+ (9+1) × 1 is 14 bits, and only 14 bits are needed for feedback;
the report format of the UCI part2 is as follows:
1010 1100000000
the former 1010 is fixed 4 bits, and the bit width length indication of the compressed segment is 10 bits in the embodiment; the following 1100000000 is the current compressed segment: the first 1 is an ACK/NACK indication, which indicates that the current compressed segment is repeated with ACK, and the following 100000000 indicates the number of repetitions, which is expressed by 2, and corresponds to 256 in 10.
In summary, the base station is told that one compressed segment is 10-bit wide by fixing 4 bits at the head, reads the MSB, knows that the complex is ACK, reads the subsequent bit, and calculates and restores the complex to 10-ary, thereby obtaining that the number of repetitions is 256.
Since the UCI part2 is variable in length, the UCI part 1 with a fixed 11bit is designed to indicate the total length of the UCI part2, and the UCI part2 in this embodiment is 14 bits in length, so the UCI part 1 source is 00,000,001,110. Therefore, the final total length of the UCI data packet received by the base station side is 25bit, and the specific format is as follows:
| UCI part1 11 | 00,000,001,110 |
| UCI part2 14 | 10,101,100,000,000 |
and finally, independently coding the UCI part 1 and the UCI part2, wherein the corresponding decoding mode at the base station side is as follows:
1) preferentially solving the content of UCI part 1 to obtain the length of UCI part 2;
2) solving the content of UCI part 2;
3) obtaining the first 4 bits of UCI part2 to obtain the bit width B +1 of the compressed segment;
4) the base station decompresses each segment in turn according to the bit width of B + 1:
for each segment, the 1 st bit is used to indicate that the continuous repetition is ACK or NACK;
the remaining B bits are used to indicate the current compressed segment repetition number.
Therefore, by the compression method proposed by the present invention, the UCI feedback of 256 bits can be compressed to 25 bits, and the compression ratio is 25/256-9.77%.
The bit compression system for reporting UCI provided by the present invention is described below, and the bit compression system for reporting UCI described below and the bit compression method for reporting UCI described above may be referred to in a corresponding manner.
