Embodiment Construction

[0047] 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.

[0048] The embodiment of the present invention provides a channel detection control method and related equipment, by dynamically adjusting the time for the base station to send the uplink authorization information to the terminal, so that the adjusted time for sending the uplink authorization information is the same as the deadline for the last downlink data transmission of the terminal When the time interval is within the preset time range, no LBT...

Abstract

The embodiment of the invention provides a channel detection control method and related equipment. The method comprises the steps: enabling a base station to obtain cutoff time information of downlink data transmission with a first terminal; receiving a dispatching request transmitted by a randomly connected second terminal through a PUCCH (physical uplink control channel), wherein the carrier employed for downlink data transmission of the first terminal is the same as the carrier employed for PUCCH transmission of the second terminal; determining the time of responding to the dispatching request to transmit uplink authorization information to the second terminal according to the cutoff time information and a preset time range, so as to enable the base station not to carry out LBT (listen before tell) detection of a channel for transmitting uplink authorization information when the base station transmits the uplink authorization information to the second terminal. According to the embodiment of the invention, the method can reduce the number of times of LBT detection of the base station, and reduces the power consumption of the base station.

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 (ListenBeforeTalk, listen before talking) mechanism is introduced in LTE, so that LTE does not occupy the channel if it detects that the...
