Abstract

Provided is a method for activating or deactivating an SRS resource, comprising: a terminal device receiving an MAC CE, the MAC CE comprising an ID of a CC set, the MAC CE further comprising an ID of at least one SRS resource, the MAC CE being used for activating or deactivating the at least one SRS resource corresponding to the CC set; or the MAC CE further comprises the ID of the SRS resource set, and the MAC CE is used for activating or deactivating the SRS resource set corresponding to the CC set. As the MAC CE can activate or deactivate the SRS resource or the SRS resource set corresponding to one CC set, and one CC set comprises a plurality of BWPs, compared with a scheme of activating or deactivating the SRS resource sets corresponding to the BWPs one by one, the method has higher efficiency and smaller signaling overhead.

Description

[0001] This application is China's application number 201980093643.6 (corresponding to PCT International Application No. PCT / CN2019 / 116405), the application date is November 7, 2019, the invention is "activated or deactivated the detection signal resources) Application for Patent Application. Technical field [0002] The present application relates to the field of communications, and more particularly to a method and apparatus for activating or deactivating detection signal resources. Background technique [0003] The Sounding Reference Signal, SRS is an uplink signal capable of providing a reference for the network device, and the network device can perform channel quality detection and estimation, beam management, etc. according to SRS. Fifth generation (5) th Generation, 5G) The mobile communication system defines a set of SRS resources. Each SRS resource set includes at least one SRS resource, one SRS resource can include the following information: antenna port number, an ...
