Abstract: A user equipment (UE) is configured to receive synchronization signal blocks (SSBs) from a wireless network to estimate frequency and timing errors. The UE receives a quasi co-location (QCL) configuration between a synchronization signal block (SSB) and at least one of a further SSB or a tracking reference signal (TRS), receives the SSB and the at least one of the further SSB or the TRS and estimates a frequency and timing error for the SSB by combining, based on the QCL configuration, measurements for the SSB and measurements for the at least one of the further SSB or the TRS.

Abstract: A user equipment (UE) is provided to implement a set of transmit power control (TPC) commands during a time domain window (TDW) including multiple physical uplink shared channel (PUSCH) transmissions. The UE can receive a configuration from the base station to configure the UE to support a power control mode and a timeline measurement related to a PUSCH transmission. The UE can receive a set of TPC commands during the TDW, determine whether a TPC command of the set of TPC commands satisfies a time constraint based on the timeline measurement, determine an effective TPC command for the set of TPC commands based on one or more TPC commands satisfying the time constraint, determine an effective delay for the effective TPC command based on the timeline measurement, and further apply the effective TPC command to a PUSCH transmission determined based on the effective delay of the effective TPC command.

Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.
