CSI FEEDBACK IN LTE/LTE-ADVANCED SYSTEMS WITH UNLICENSED SPECTRUM

摘要

Channel state information (CSI) feedback in long term evolution (LTE) and LTE-Advanced (LTE-A) networks including unlicensed spectrum is disclosed in which a base station obtains clear channel assessment (CCA) result information from neighboring base stations, either directly or by determining such results from measurement or reports from user equipment (UE) served by the base station. The base station may then generate control signaling based on the CCA result information for transmission to the one or more UEs served by the base station.

主权项

1. A method of wireless communication, comprising:
obtaining, by a base station, clear channel assessment (CCA) result information for a plurality of neighboring base stations; generating, by the base station, control signaling for one or more user equipments (UEs) served by the base station, wherein the control signaling is based, at least in part, on the CCA result information; and transmitting the control signaling to the one or more UEs.
