Patent number: 10470064Abstract: User Equipment (UE) and base station (eNB) apparatus and methodology for radio resource management reporting. The UE receives reference signals from at least one antenna port of an eNB via a plurality of receive antennas of the UE. The UE performs received signal measurement of at least a portion of the reference signals for a plurality of eNB antenna port and UE receive antenna combinational groupings to produce enhanced received signal quality (eRSQ) measurements that represent spatial characteristics of the reference signaling as received by the UE. The UE may send a report to the eNB based on the eRSQ measurements, with the report being indicative of spatial multiplexing layer availability of the UE to be served by the eNB.Type: GrantFiled: December 23, 2015Date of Patent: November 5, 2019Assignee: Intel CorporationInventors: Alexei Vladimirovich Davydov, Ilya Bolotin, Alexander Alexandrovich Maltsev, Jr., Gregory Vladimirovich Morozov, Vadim Sergeyevich Sergeyev
