Method for transmitting channel state information report, communication device, and storage medium
Technical Field
The present disclosure relates to the field of wireless communications technologies, and in particular, to a method for transmitting a channel state information report, a communication device, and a storage medium.
Background
The multi-antenna technology has become a key technology for improving the performance of a wireless communication system, and is widely applied to various wireless communication systems such as a cellular network, satellite communication, the Internet of things and the like. Multi-antenna techniques include multiple-input multiple-output (multiple input multiple output, MIMO), multi-transmission node joint transmission (joint transmission, JT), high frequency beamforming, and the like. In multi-antenna technology, especially in a system based on frequency division multiplexing, to obtain good transmission performance, a communication node that needs to transmit information can obtain accurate Channel State Information (CSI).
However, it is not easy to obtain accurate CSI. The channel information is changed along with the environment, and multipath effect, doppler spread, noise interference, feedback overhead and other factors may affect the accuracy of the CSI. To overcome these challenges, researchers have been exploring various methods of improving CSI accuracy. For example, by introducing advanced information processing techniques, the accuracy of CSI acquisition is improved by utilizing historical channel information, current channel information, and the like. Among them, advanced information processing techniques, including but not limited to artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) techniques, by which more accurate channel state information than conventional methods can be obtained without an increase in overhead. However, as time goes by, the historical channel information may be aged, for example, the correlation between the historical channel information and the channel information at the current moment may not meet the preset condition, or the compression performance of the channel information may be reduced due to the reason that the base station side does not receive the channel information fed back by the terminal. How to improve the performance or efficiency of channel state information compression is a matter of investigation.

Detailed Description
The following description of the technical solutions in the present disclosure will be made clearly and completely with reference to the accompanying drawings in the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
It is noted that in this disclosure, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
In the description of the present disclosure, unless otherwise indicated, "/" means "or" and, for example, a/B may mean a or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present application, and have no particular meaning in themselves, and thus "module", "component", or "unit" may be used in a mixed manner.
As described in the background art, the multi-antenna technology is an important technology for improving spectrum efficiency in the field of wireless communication, and to perform multi-antenna performance, accurate CSI needs to be obtained. For example, channel information is compressed based on advanced techniques, including but not limited to artificial intelligence AI, to obtain more accurate CSI without increasing overhead.
Illustratively, as shown in fig. 1, an encoder (Encoder) is adopted at the transmitting end to compress the channel state information V n, output compressed channel state information V En,n, and then quantize the compressed channel state information V Q,n by a quantizer (Quantizer); when the quantized channel state information V Q,n is transmitted to a receiving end (typically a base station), the receiving end dequantizes the quantized channel state information V Q,n by using an dequantizer (De-Quantizer) to obtain V De,n, takes V De,n as an input of a Decoder, and outputs channel state information V n'. It can be seen that, in the above process, when the encoder performs encoding, the encoder needs to use the historical state parameter W n (such as the historical state parameter output by the last encoder) and the current channel state information Vn to perform encoding; the decoder needs to use the historical state parameter W n' (such as the historical state parameter of the last decoder output) to decode when decoding. The historical state parameters of the encoder and the historical state parameters of the decoder are preferably updated or changed synchronously so that the inputs of the encoder and the decoder are matched to obtain the best performance.
From the above analysis, it can be seen that the reliability of the historical state parameters W n and W n' are compared in such a way that the CSI performance is improved by using the historical channel information or the state parameters of the processed output of the historical channel information. However, as time progresses, the historical state parameters may suffer from aging problems, such as, for example, the historical state parameters accumulating errors over time. For aperiodic CSI reporting, the problem of different time differences between different historical state parameters and the current CSI acquisition may occur; or the historical channel information and the current channel information no longer have a temporal correlation, or the scene is changed, for example, from indoor to outdoor, from a city microcell (Urban Microcell, UMI) to a city Macrocell (UMA), and so on. Resulting in degradation of the performance of channel information compression.
In some embodiments, the historical state parameters may also be a concept called one of: status parameters, accumulated historical status information, output channel status information of historical channel information, status variables, historical status variables, and the like. To distinguish between input and output state parameters in the encoder, and in the future between input and output state parameters in the decoder, first, second, etc. modifications, such as a first state parameter, a second state parameter, a third state parameter, a fourth state parameter, are added. In some examples, to distinguish between the first initialized encoder or decoded state parameter and the historical state parameter output by other modules, the first initialized encoder or decoded state parameter is also referred to as an initial first state parameter, and an initial third state parameter, respectively. In some examples, the state parameter is C real numbers. In one example, the state parameters are C vectors. In one example, the state parameters are C matrices or tensors. In some examples, C is a positive integer. In some examples, the vector and matrix may be presented in the form of an array.
Aiming at the technical problems, the embodiment of the disclosure provides a transmission method of a channel state information report, which is characterized in that: firstly, determining a first state parameter according to a contracted mode; or determining a first state parameter according to the mode of signaling transmission; then, according to the first state parameter and the first channel state information, determining second channel state information and second state parameters; and generating and transmitting a channel state information report according to the second channel state information. It can be seen that, before compressing the first channel state information, the embodiment of the disclosure determines the first state parameter in a contracted manner or a signaling transmission manner, so that the first state parameter can be updated in real time, and the problem that the channel state information compression performance is reduced due to ageing or failure of the state parameter can be solved, thereby improving the channel information compression performance.
