Embodiment 1

[0019] The method embodiment provided in Embodiment 1 of the present application may be executed in a device, a computer terminal, or a similar computing device. Take running on the device as an example, figure 1 It is a block diagram of the hardware structure of the equipment of the method for encoding channel state information CSI according to the embodiment of the present invention. Such as figure 1 As shown, the device 10 may include one or more (only one is shown in the figure) processors 102 (the processors 102 may include but not limited to processing devices such as microprocessors MCUs or programmable logic devices FPGAs), for storage Data storage 104, and transmission means 106 for communication functions. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, device 10 may also include figure 1 more or fewer componen...

Embodiment approach 1

[0074] Such as image 3 As shown, the BER corresponding to the location with a small index number is also small. Therefore, in this embodiment, the method of placing CSI in the location index set is:

[0075] (1) Place the first type of information bits at the (L_CRI+L_RI) indexes with the smallest serial number in the position index;

[0076] (2) place the fourth type of information bit at the L_A index with the largest index in the position index;

[0077] (3.1) Place the second type of information bits and the third type of information bits in the remaining positions according to the index size (from small to large or from large to small) in turn;

[0078] At this time, the sequence of various types of information in the CSI report is as follows:

[0079] Type I information bits Type II information bits Type III information bits Type 4 Information Bits

[0080] or,

[0081] Type I information bits Type III information bits Type II infor...

Embodiment approach 2

[0089] Such as image 3 As shown, the position with a small index number corresponds to a small BER. Therefore, in this embodiment, the way to place CSI in the index set is:

[0090] (1) Place the first type of information bits at the (L_CRI+L_RI) indexes with the smallest serial number in the position index;

[0091] (2) placing the second type of information bits at the L_Pad indices with the lowest reliability in the position index;

[0092] (3.1) Place the third type of information bits and the fourth type of information bits in the remaining positions according to the index size (from small to large or from large to small) in turn; or,

[0093] (3.2) Place the third type of information bits and the fourth type of information bits in the remaining positions in sequence according to the index reliability (from small to large or from large to small).

Abstract

The present invention provides a channel state information CSI encoding method and device, storage medium and processor, wherein the method includes: according to the index in the position index set, the first type of CSI information bits are placed in the first position index set One type of position index, and determine the second type of information bit of CSI, the third type of information bit of CSI and the fourth type of information bit from the position index set except the first type of position index determined by the first type of information bit The index of the class information bit in the index set; or place the fourth class information bit on the fourth class position index of the index set, from the position index set except the fourth class position index determined by the fourth class information bit The indexes of the first type information bits, the second type information bits and the third type information bits of the CSI in the index set are determined in the index. The invention solves the problem in the related art that the positions of various types of information in the CSI report cannot be reasonably arranged.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for encoding CSI of channel state information, a storage medium and a processor. Background technique [0002] The control channel in 5G NR (New Radio) adopts the Polar code coding method. The coding process of the Polar code is x=u*G, where u includes information bits and parity bits, and x is The coded bit sequence, G is a generator matrix (Generator Matrix) of the Polar code, and the dimension of the generator matrix G is N*N, where N is a power of 2. For polar codes, the reliability (reliability) and BER (BitError Ratio, bit error rate) of different input bit indexes (bit index, 0~N-1) are different. In order to improve the performance of polar codes, it is usually necessary to The polar code input bit sequence is mapped to an index position with high reliability or low BER. [0003] In 5G NR (New Radio, New Radio), a joint coding (Joint coding) mec...
