Abstract
A first base station selects a subset of channels of an unlicensed frequency band based on indications of energy received over the channels. The first base station transmits one or more messages instructing user equipment to monitor the subset of channels and report information indicating whether at least one second base station is transmitting over the subset of channels. User equipment monitors the subset of channels of the unlicensed frequency band in response to receiving the one or more messages from a first base station indicating the subset of channels. The user equipment transmits one or more messages including information indicating whether one or more second base stations are transmitting over the subset of channels.
