Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.

Abstract: A user equipment (UE) device is disclosed. The UE device comprises a processor configured to perform operations comprising receiving a downlink control information (DCI) from a base station. In some embodiments, the DCI comprises an indication to trigger a Type-3 hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback signal. The operations further comprise generating the Type-3 HARQ ACK feedback signal, based on processing the DCI. In some embodiments, the Type-3 HARQ ACK feedback signal comprises one or more HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release(s). In some embodiments, each of the one or more HARQ-ACK bits for SPS PDSCH release(s) is adapted to include HARQ-ACK information for an SPS PDSCH release associated with the UE. Further, the operations comprise sending the Type-3 HARQ-ACK feedback signal to the base station.

Abstract: Systems, methods and circuitries are provided for performing UE autonomous selection in a vehicle-to-anything (V2X) communication environment, that includes one or more processors configured to schedule resources for discontinuous periodic transmission having a scheduled discontinuous time period in which scheduled resources are not transmitted. The one or more processors are further configured to perform a monitoring operation at the scheduled discontinuous time period, the monitoring operation comprising a monitoring for a collision of scheduled resources of the evaluating UE with scheduled resources of a competing UE, and selectively perform a corrective action when a collision of scheduled resources of the evaluating UE with scheduled resources of the competing UE is detected during the monitoring operation.

Abstract: Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A UE can be polled by receiving a DCI that indicates dynamically updated resources. UE can be configured to find the DCI and use the resources to send a scheduling request (SR). Other aspects are described.

Abstract: This disclosure relates to techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals for multi-transmission-reception-point operation in a wireless communication system. A wireless device may establish wireless links with multiple transmission-reception-points of a cellular network. The wireless device may receive downlink control information. The wireless device may determine a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information. Signals received according to the quasi-co-located assumption for aperiodic channel state information reference signals may be buffered by the wireless device if a scheduling offset for the downlink control information is below a scheduling offset threshold.

Abstract: Features for increasing sounding reference signal (SRS) resource capacity for wireless communications may include introducing a larger comb size with comb hopping, providing support to determine the slot offset and/or comb offset for aperiodic SRS based on downlink control information (DCI) alone or based on both DCI and radio resource control (RRC), applying RB level frequency hopping within an SRS resource across different symbols, and/or applying time domain orthogonal cover code (TD-OCC) to symbols within an SRS resource. The TD-OCC may be applied to SRS for codebook, non-codebook and antenna switching, and may also be applied simultaneously with comb hopping and/or RB level hopping in certain scenarios.
