Abstract

The invention provides a method and device for channel occupation indication, being beneficial to saving resources. The method comprises the steps that a network device sends indication information containing channel occupation information, wherein the indication information comprises a group identifier corresponding to a terminal device group, and through the group identifier, the terminal devicein the terminal device group corresponding to the group identifier can be indicated to feed back channel occupation information; and the terminal device in the terminal device group corresponding tothe group identifier sends feedback information including information occupied by the channel of the terminal device. Based on the application, by grouping the terminal devices and introducing the group identifiers, the resource cost required for notifying the terminal devices to feed back channel occupation can be reduced.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a method and device for channel occupation indication. Background technique [0002] The spectrum used by the wireless communication system is divided into two types, licensed spectrum (licensed spectrum) and unlicensed spectrum (unlicensed spectrum). For commercial mobile communication systems, operators need to auction authorized spectrum, and after obtaining the authorization, they can use the corresponding spectrum to carry out mobile communication operations. Unlicensed spectrum does not need to be auctioned, and anyone can legally use these bands, such as wireless-fidelity (Wi-Fi) devices on the 2.4 gigahertz (GHz) and 5GHz bands. [0003] In the prior art, after the sending device competes for the channel, it sends a channel occupation signal to other surrounding devices, and the channel occupation signal indicates to other devices the transmission time that t...
