Abstract

The invention discloses a method and device for indicating channel access. The method comprises the steps: receiving first indication information sent by a network device, and obtaining a channel access parameter according to the first indication information, wherein the channel access parameter is used for determining channel access of target uplink transmission; receiving the first indication information sent by the network device, wherein the first indication information can be indicated based on the command field of the existing information, so the channel access of the target uplink transmission does not need to be indicated by newly adding the command field, the bit overhead of the information is reduced, the design implementation complexity is reduced, and the technical problems that the size of the information on the unlicensed spectrum is inconsistent with the size of the information on the licensed spectrum, and the overhead of the information on the unlicensed spectrum is large are solved.

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the China Patent Office on October 17, 2019, with application number 2019800735935, and the title of the invention is "Method and Device for Indicating Channel Access", the entire content of which is incorporated in this application by reference middle. technical field [0002] The present application relates to the field of communication technologies, and in particular to a method and device for indicating channel access. Background technique [0003] The unlicensed spectrum is the spectrum allocated by the country and region that can be used for radio device communication. This spectrum is usually considered a shared spectrum, that is, communication devices in different communication systems can be used as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply to the government for exclusive sp...
