Abstract: The present invention relates to a wireless access system that supports unlicensed bands, and relates to a method for reporting channel state information when a partial subframe (pSF) is formed. A method for user equipment (UE) reporting channel state information (CSI) in a wireless access system that supports unlicensed bands according to an embodiment of the present invention may comprise the steps of: receiving a downlink burst configured to an unlicensed band cell (U cell) supporting unlicensed bands as far as a certain subframe; measuring CSI with respect to the downlink burst; and reporting the measured CSI to a base station. In this regard, if a pSF is included in the downlink burst, the UE does not consider the pSF to be a valid downlink subframe for CSI measurement, and the pSF may be formed to have a smaller size than a general subframe.

Abstract: A multi-cell/multicast coordination entity (MCE) determines a cluster to which a vehicle-to-everything (V2X) message. The MCE receives a first session start message, which includes a temporary mobile group identity (TMGI), quality of services (QoS) parameters, and a list of cells, from a V2X application server and determines a cluster, which contains group of cells, to which V2X message is to be broadcast, based on the received TMGI, QoS parameters, and list of cells. Upon determining the cluster, the MCE transmits a second session start message, which includes an indication to notify eNodeB (eNB) to wait for scheduling information, to eNBs corresponding to the determined cluster, and transmits MBMS scheduling information to the eNBs. Further, update of the cluster may be triggered from the V2X application server or from the eNB with limited feedback.
