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: Techniques discussed herein can facilitate enhancements to measurement for a User Equipment (UE) in Radio Resource Control (RRC) Connected mode for configuration of Carrier Aggregation (CA) and/or Dual Connectivity (DC). One example embodiment comprises a UE device comprising a processor configured to perform operations comprising: transmitting a UE Assistance Information message comprising a measurement request; receiving a first RRCReconfiguration message comprising a measConfig information element (IE); performing one or more measurements on each of on one or more frequencies based at least on the RRC measConfig IE, wherein the one or more frequencies comprise at least one non-serving frequency associated with a neighboring cell; transmitting a MeasurementReport message that indicates the one or more measurements for at least one of the one or more frequencies; and receiving a second RRCReconfiguration message that configures the UE with the at least one of the one or more frequencies.

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.

Abstract: Apparatuses, systems, and methods for user equipment device (UE) uplink antenna panel selection. The UE may determine, based on at least one condition, to perform a beam switch from a current beam being used for communications with a base station. The UE may transmit, to the base station, an indication of an antenna panel status that may include an indication of a latency associated with the beam switch. The UE may receive, from the base station, an indication to switch to a target beam and to perform the switch, based on the indication, to the target beam. The indication of the antenna panel status may include a beam switching latency level for each beam in a beam report, a beam switch request that may indicate the target beam, and/or a beam switch request that may indicate that an antenna panel switch is to be applied by the UE.

Abstract: An example technique for security key derivation in a wireless system includes: sending a radio resource control (RRC) suspend message from a first node, to a first user device, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value; releasing access stratum (AS) resources associated with the first user device; deriving a first node key based on the first NCC value; receiving a first uplink message from the first user device without allocating AS resources to the first user device; and unscrambling the first uplink message based on the first NCC value.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform URLLC scheme selection. The UE may connect to at least one base station. The UE may determine scheduling of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) are within a threshold duration. Based on the PDCCH and the PDSCH being scheduled within the threshold duration, select one or more transmission control indicator (TCI) states for receiving the PDSCH irrespective of TCI state(s) indicated in the PDCCH. The UE may receive the PDSCH using the selected one or more TCI states.

Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A cellular base station may provide a downlink control information transmission to a wireless device scheduling downlink transmissions to the wireless device from multiple transmission reception points. The downlink control information may include information that can be used by the wireless device to determine any or all of physical resource block bundling sizes, frequency domain resource allocations, modulation and coding schemes, redundancy versions, phase tracking reference signal configurations, and any of various other possible types of configuration information for the downlink transmissions. The wireless device may receive the downlink transmissions from the plurality of transmission reception points in accordance with the downlink control information.
