Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] The 3GPP standard organization approved the LAA (Licensed-Assisted Access) research project based on LTE (Long Term Evolution, long-term evolution) in the 65th plenary meeting of TSGRAN. This project mainly studies how to deploy LTE on unlicensed spectrum. network, so as to achieve fair and effective use of unlicensed spectrum and improve the data transmission rate of the LTE system. It should be noted that the embodiments of the present in...

Abstract

An embodiment of the present invention provides a channel detection control method and related devices. The method includes: receiving a scheduling grant for performing uplink services on a physical uplink shared channel sent by a base station. The uplink scheduling grant includes LBT type information, and the LBT type The information is used to instruct the UE to perform the corresponding LBT detection operation on the target channel located in the unlicensed spectrum, and determine whether to perform the LBT detection operation on the target channel located in the unlicensed spectrum indicated by the LBT type information according to the interval specific manner; when the UE determines the specific manner of performing the LBT detection operation indicated by the LBT type information in the uplink scheduling grant information according to the interval, the UE determines according to the LBT detection operation in the uplink scheduling grant information The type information performs the LBT detection operation on the target channel located in the unlicensed spectrum. Implementing the embodiments of the present invention can improve the utilization rate of spectrum resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel detection control method and related equipment. Background technique [0002] With the rapid increase of communication traffic, licensed spectrum is increasingly insufficient to provide higher network capacity. In order to further improve the utilization rate of spectrum resources, the use of unlicensed spectrum can be expanded on the basis of licensed spectrum. The 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) organization proposed LAA (Licensed Assisted Access, Authorized Assisted Access) technology to realize the use of unlicensed spectrum on the basis of LTE (Long Term Evolution, Long Term Evolution) licensed spectrum. In order to better coexist with the unlicensed spectrum, the LBT (Listen Before Talk) mechanism is introduced in LTE, so that LTE will not occupy the channel if it detects that the channel is busy on t...
