Embodiment Construction

[0044]In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the drawings and embodiments in the embodiments of the present invention.

[0045]figure 1 It is a schematic diagram of an application scenario based on the transmission method for dynamically adjusting a beam set provided by an embodiment of the present invention. Refer tofigure 1 MIMO communication technology is adopted between the base station 101 and the terminal 102. The base station 101 configures a set of N beams, and indicates to the terminal 102 through high-level signaling. The beams in the beam set can be indicated by a beam index or a codebook index, and the foregoing codebook index has a corresponding relationship with beams. For example, the foregoing codebook index may be a precoding matrix indicator in a Long Term Evolution (L...

Abstract

Embodiments of the present invention relate to a transmission method, a base station, and a terminal for dynamically adjusting beam sets. The method includes: the base station sends first indication information to the terminal through the first layer signaling, and the first indication information is used to indicate the first beam set; the base station sends the second indication to the terminal through the second layer signaling information, the second indication information is used to indicate at least one beam in the first beam set; the base station uses the at least one beam to send data to the terminal. The embodiment of the present invention can solve the problem of signal attenuation caused by occlusion.

Description

Technical field[0001]The present invention relates to the field of communications, and in particular to a transmission method, base station and terminal for dynamically adjusting a beam set.Background technique[0002]The 5th Generation (5G) mobile communication system enables future growth of mobile data traffic, massive Internet of Things, and diversified new services and application scenarios. In addition to acting as a unified connection framework, the basic 5G New Radio (NR) of the new generation of cellular networks is also expected to increase the data speed, capacity, latency, reliability, efficiency and coverage of the network to a whole new level. And will make full use of every bit of available spectrum resources. 5G based on Orthogonal Frequency Division Multiplexing (OFDM) new air interface design will become a global standard, supporting the diversified deployment of 5G equipment and covering a diversified spectrum (including coverage of low and high frequency bands) , B...
