Abstract: A method of beam reciprocity state reporting and uplink beam management in wireless communication systems with beamforming is proposed. In one novel aspect, a BS configures one or more resource sets to a UE for uplink beam management. The one or more resource sets are allocated for UE to transmit UL reference signals using a number of UE beams. The number of UE beams to be trained is reported by the UE, e.g., via a “UE beam reciprocity state (update)” message. The BS also indicates whether a fixed UE TX beam or which UE TX beam is used for transmission, or indicates whether different UE TX beams are used for transmission of different resources in a resource set. The BS then feedback measurement results for UE to choose a proper TX beam.

Abstract: Described techniques provide for transmission of synchronization signals using frequency hopping across a number of hopping frequencies in unlicensed or shared radio frequency spectrum. A base station may identify a set of hop frequencies for transmitting synchronization signals, and transmit synchronization signals using a hopping pattern over the hop frequencies. A user equipment (UE) seeking to identify the base station may monitor one or more of the hop frequencies to identify one or more synchronization signals on the hop frequency. A system timing may be identified in some cases, and one or more base station IDs may be identified. In some cases, a hop frequency may be monitored for a duration that may span the transmission of two or more synchronization signals of a particular base station, based on a periodicity of synchronization signal transmissions on each hop frequency.
