Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing vehicle-to-everything sidelink communication. A wireless device may receive vehicle-to-everything resource pool configuration information and sidelink control information. A number of resource elements allocated for a vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the resource pool configuration information and the sidelink control information. A transport block size for the vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the number of resource elements allocated for the vehicle-to-everything physical sidelink shared channel. A low density parity check base graph may be selected for the vehicle-to-everything physical sidelink shared channel based at least in part on the determined transport block size.

Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

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: A method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device that specifies PDCCH monitoring for one subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs) that are related to a spectrum in 5G new radio (NR) above 52.6 GHz are described. In one embodiment, the monitoring limits associated with each of the SCSs are applied per slot per CC and the user equipment (UE) decode complexity associated with performing the monitoring limits for the different SCSs in the group is equal. In one embodiment, the monitoring limits associated with each of the SCSs are for a slot group of a plurality of slots and are for application over a duration of the slot group.

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.
