Embodiment Construction

[0044] In order to make the purpose, 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 of 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 the beam set provided by the embodiment of the present invention. refer to figure 1 , the 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-layer signaling. The beam in the beam set can be indicated by a beam index or a codebook index, and there is a corresponding relationship between the codebook index and the beam. For example, the above codebook index can be a precoding matrix indicator in a Long...

Abstract

Embodiments of the present invention relate to a transmission method, base station and terminal for dynamically adjusting a beam set. The method comprises the steps of a base station sending first indication information to a terminal through a first layer of signaling, wherein the first indication information is used for indicating a first beam set; the base station sending second indication information to the terminal through a second layer of signaling, wherein the second indication information is used for indicating at least one beam in the first beam set; and the base station transmittingdata to the terminal through the at least one beam. According to the embodiment of the invention, the problem of signal attenuation caused by shielding can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission method for dynamically adjusting a beam set, a base station and a terminal. Background technique [0002] The fifth generation (5th Generation, 5G) mobile communication system makes it possible for future mobile data traffic growth, massive Internet of Things, and diversified new services and application scenarios. In addition to serving as a unified connection framework, the basic 5G new air interface (New Radio, NR) of the new generation of cellular network is also expected to improve the data speed, capacity, delay, reliability, efficiency and coverage of the network to a 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 diversified deployment of 5G equipment, covering diverse spectrum (including low-ban...
