Embodiment 1

[0020] 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

[0075] 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:

[0076] (1) Place the first type of information bits at the (L_CRI+L_RI) indexes with the smallest serial number in the position index;

[0077] (2) place the fourth type of information bit at the L_A index with the largest index in the position index;

[0078] (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;

[0079] At this time, the sequence of various types of information in the CSI report is as follows:

[0080] Type I information bits Type II information bits Type III information bits Type 4 Information Bits

[0081] or,

[0082] Type I information bits Type III information bits Type II infor...

Embodiment approach 2

[0090] 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:

[0091] (1) Place the first type of information bits at the (L_CRI+L_RI) indexes with the smallest serial number in the position index;

[0092] (2) placing the second type of information bits at the L_Pad indices with the lowest reliability in the position index;

[0093] (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,

[0094] (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 invention provides a channel state information (CSI) coding method and device, a storage medium and a processor, and the method comprises the steps: placing a first type of information bit of CSI on a first type of position index of a position index set according to an index in the position index set, determining indexes of a second type of information bits of the CSI, a third type of information bits of the CSI and a fourth type of information bits in the index set from indexes except the first type of position indexes determined by the first type of information bits in the position index set; or placing the fourth type of information bits on the fourth type of position indexes of the index set, and determining the indexes of the first type of information bits, the second type of information bits and the third type of information bits of the CSI in the index set from the indexes except the fourth type of position indexes determined by the fourth type of information bits in the position index set. According to the invention, the problem that the positions of various types of information in CSI reporting cannot be reasonably arranged in the prior art is solved.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number "201711149064.8", the application date is "November 17, 2017", and the title is "Channel State Information CSI Coding Method and Device, Storage Medium and Processor". technical field [0002] 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 [0003] 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 ...
