FRAME STRUCTURE AND CONTROL SIGNALING FOR DOWNLINK COORDINATED MULTI-POINT (COMP) TRANSMISSION

摘要

Establishing a coordinated multi-point (CoMP) cooperating set among a plurality of access nodes including an anchor access node. The anchor access node receives one or more user equipment (UE) measurement reports related to the UEs' channel measurements of one or more of the plurality of access nodes. The anchor access node determines whether to employ CoMP transmissions based on the UEs' measurement reports. Responsive to determining to employ CoMP transmissions, the anchor access node adds the at least one of the plurality of access nodes to a CoMP candidate list. The anchor access node transmits a request to the at least one of the plurality of access nodes to initiate CoMP transmissions. Responsive to receiving an acknowledgement signal from the at least one of the plurality of access nodes, the second access node is added to the CoMP cooperating set.
