Title:
METHOD, DEVICE, AND APPARATUS FOR TRANSMITTING AND RECEIVING A REQUEST SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/237832
Kind Code:
A1
Abstract:
Disclosed is a method, device, apparatus for transmitting and receiving a request signal, comprising: a base station determines a channel occupancy request signal to be transmitted, the channel occupancy request signal being a request signal for requesting channel occupancy to a terminal after the base station executes a listen-before-talk operation on the direction corresponding to at least one beam; the base station schedules transmission of the channel occupancy request signal on a downlink control channel; the terminal detects the downlink control channel that schedules the transmission of the channel occupancy request signal; and the terminal receives the channel occupancy request signal according to a detection result. The use of the present invention overcomes a defect of the prior art that has no design for the channel occupancy request signal, and implements transmission of an eNB channel occupancy request signal. Furthermore, the solution further provides a solution that can achieve the lowest power consumption.
