US 2021/0243803 A1 · SYSTEMS AND METHODS FOR CHANNEL ACCESS

Abstract

A system and method for channel access in licensed and unlicensed spectrums are disclosed herein. In one embodiment, a method performed by a communication node, includes: detection of an idle channel associated with a communication device after performance of a channel access procedure; transmitting an initial signal after the detection of the idle channel, wherein the initial signal configures a communication device to start detecting a control channel; and transmitting a control signal using the control channel to the communication device after the transmitting the initial signal.
