Abstract

The invention provides a method for updating a beam and a communication device, so that a terminal device can acquire a plurality of sending beams after resource updating, and signaling overhead can be saved as much as possible. The method may comprise: a terminal device receiving a first signaling, the first signaling comprising information of one or more available beams of a first resource; the terminal device receives a second signaling, the second signaling comprising information of one or more available beams of a second resource, a sending beam of the first resource being the same as a sending beam of the second resource, the sending beam of the first resource being a part or all of the available beams of the first resource, and the sending beam of the second resource being a part of or all of the available beams of the second resource; the sending beams of the second resource are part or all of the available beams of the second resource; the terminal equipment receives a third signaling, wherein the third signaling comprises beam updating information of the first resource; and the terminal equipment updates the sending beam of the second resource based on the beam updating information of the first resource.

Description

[0001] This application is a divisional application, the application number of the original application is 201910244846.2, the original application date is March 28, 2019, and the entire contents of the original application are incorporated into this application by reference. technical field [0002] The present application relates to the field of communications, and in particular, to a method and a communication device for updating a beam. Background technique [0003] In the communication process, such as high-frequency communication, network equipment and terminal equipment communicate through directional beams. [0004] Generally speaking, the selection of the receiving and sending beams of the terminal equipment needs to rely on the beam indication information provided by the network equipment. For example, the network equipment sends a signaling to the terminal equipment, and the signaling can indicate the physical uplink control channel of the terminal equipment (physi...
