  • Patent number: 11637602
    Abstract: Devices for and methods of synchronous beam refinement using a beam refinement reference signal (BRRS) are generally described. In one example embodiment, a UE receives BRRS information indicating switching of a Tx beam. The UE then uses this information to switch an associated Rx beam. In some embodiments, timing information is used to match the switching times. In some embodiments, DCI and CSI-RS operations are used to determine switching for the synchronous beam refinement.

  • Patent number: 11622377
    Abstract: Technology for a user equipment (UE) using a self-contained scheduling resource to communicate with an eNodeB within a wireless communication network is disclosed. The UE can select, at the UE, a selected eNodeB transmission (Tx) beam and a selected UE reception (Rx) beam based on a highest power beamforming reference signal (BRS) received power (BRS-RP). The UE can signal a transceiver of the UE to transmit to the eNodeB a scheduling request (SR), using the selected Rx beam, on a scheduling request (SR) resource in a self-contained subframe according to a time and frequency location of the selected eNodeB Tx beam. The UE can process an advanced physical downlink control channel (xPDCCH), received from the eNodeB, for an uplink (UL) grant using the selected UE RX beam.

  • Publication number: 20230023442
    Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.
