PERFORMING LISTEN-BEFORE-TALK PROCEDURES ON BANDWIDTH PARTS

摘要

This document describes techniques and apparatuses for performing listen-before-talk procedures on bandwidth parts. These techniques include a user equipment (UE) initiating a first listen-before-talk (LBT) procedure on an active bandwidth part used in a radio resource control (RRC) connection between a UE and a base station (404). During the first LBT procedure, the UE receives a configuration message from the base station instructing the UE to change the active bandwidth part from the first bandwidth part to a second bandwidth part (406). Responsively, the UE changes the active bandwidth part (408) and initiates a second LBT procedure on the second bandwidth part (410).
