Abstract: A method, system and compute readable media for determining the strongest of a plurality of antenna beam pairs. A plurality of antenna beams are generated at user equipment (UE) and a plurality of antenna beams are generated at an evolved Node-B (eNB), the pluralities forming respective antenna beam pairs. The generated antenna beams are received at the UE. A plurality of the received antenna beams specified by a coarse codebook at the UE is searched to determine the strongest coarse codebook beam. The strongest coarse codebook beam is refined by searching each of a plurality of received antenna beams specified by a fine codebook and associated with the strongest coarse codebook antenna beam, to determine the strongest refined antenna beam pair. The strongest fine codebook beam pair, along with the identity of the codebook used to specify the strongest fine codebook beam pair, is reported to the eNB.

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.
