Embodiment Construction

[0109] In order to make the purpose, technical solutions and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments. Wherein, in the description of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0110] like figure 1 As shown in , it is a schematic diagram of a possible network architecture applicable to this application, including network devices and at least one terminal device. The network device and the terminal device can work on a new radio (new radio, NR) communication system, and the terminal device can communicate with the network device through the NR communication system. The network device and the terminal device may also work on other communication systems, which is not limited in this embodiment of the...

Abstract

The present application provides a communication method and device. The method includes: introducing a brand new indication field in the CSI. Specifically, by first reporting the union of the frequency-domain basis vectors corresponding to all spatial layers, the unselected vectors in the candidate frequency-domain basis vector set are excluded, and the size of the indicated candidate frequency-domain basis vector set is further reduced. Then, it is only necessary to indicate which frequency domain basis vectors in the union of the frequency domain basis vectors corresponding to each spatial layer are in the frequency domain basis vectors, thereby reducing the indication overhead.

Description

[0001] This application claims the priority of a Chinese patent application filed with the Intellectual Property Office of the People's Republic of China on April 9, 2019, with the application number 201910282453.0 and the title of the invention "A communication method and device", the entire contents of which are incorporated herein by reference Applying. technical field [0002] The present application relates to the technical field of mobile communication, and in particular to a communication method and device. Background technique [0003] The multiple input and multiple output (Multiple Input and Multiple Output, MIMO) technology is the core technology of the Long Term Evolution (LTE) system and the fifth generation (5th generation, 5G) new radio (new radio, NR). [0004] Based on all or part of downlink channel state information (Channel State Information, CSI), precoding (Precoding) technology can effectively improve signal transmission performance and system capacity...
