Abstract:
Devices and methods of beamforming are generally described. A UE transmits to an eNB a BRSRP report having selected BRSRP values and associated BRS IDs. An active link list, a CSI resource indication, and a first active link are used to measure the CSI resource and CSI feedback is sent. A serving link ID is provided to indicate a second active link to use for control and data reception. Rx beams are trained based on multiple instances of each BRS and the eNB supplies selection criteria for the BRSRP report. The Rx beams are refined based on BRRS and the second active link is dependent on BRRSRP or CSI feedback. When configured for dual beam operation, the BRSRP feedback corresponds to BRSRP value pairs and dual Rx beams associated with a pair of serving link IDs are used.
