Abstract: A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises a processor configured to receive a first downlink control information (DCI) for scheduling a first physical downlink shared channel (PDSCH). The first DCI includes a non-numerical (NN) value of K1 for hybrid automatic repeat request (HARQ)-ACK feedback. The processor is further configured to determine a first priority class associated with the first PDSCH, and determine K1 value and priority class associated with one or more subsequent PDSCH received from the base station, until a selected PDSCH having a numerical K1 value and a same priority class as the first priority class is identified. Further, the processor is configured to provide HARQ feedback associated with the first PDSCH using a PUCCH/PUSCH occasion indicated by a second DCI scheduling the selected PDSCH.

Abstract: SL-DRX involves both Uu and PC5 interfaces. For an RRC_CONNECTED UE (also referred to as a connected mode UE, or simply connected UE), several SL-DRX enhancements are described in this disclosure to trigger SL DRX and share configurations. Alignment of SL-DRX alignment with Uu-DRX (referred to as Uu/SL DRX alignment or simply alignment) is also described, as an optional feature (since not all schedules can temporally align).

Abstract: This disclosure relates to techniques for handling timing alignment for configured grant based small data transmissions in inactive mode in a wireless communication system. A wireless device may establish a radio resource control connection with a cellular base station. The wireless device may receive an indication to release the radio resource control connection. The indication to release the radio resource control connection may configure resources for performing uplink transmissions while in the radio resource control inactive mode. A timing advance may be maintained while in the radio resource control inactive mode. An uplink transmission may be performed using resources configured for performing uplink transmissions while in the radio resource control inactive mode. The uplink transmission may be performed using the timing advance.

Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: Methods, systems, and devices for signaling in cast-type indication for a wireless communication system may include receiving, at a first user equipment (UE), a first stage sidelink control information (SCI) format from a second UE, decoding the first stage SCI format, determining a second stage SCI format using the decoded first stage SCI format, decoding the second stage SCI format, and determining a sidelink feedback status using the second stage SCI format. The sidelink feedback status may indicate whether sidelink feedback is enabled or not enabled. Second stage SCI content may include a distance setting associated with a communication range between the first UE and the second UE.

Abstract: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.

Abstract: Apparatuses, systems, and methods may use an smtc information element or an smtc2-LP information element to calculate timing of a first measurement period to evaluate a serving cell while the UE is in idle mode or inactive mode. Additionally, apparatuses, systems, and methods may use the smtc information element or the smtc2-LP information element to calculate timing of a second measurement period to evaluate intra-frequency cells while the UE is in idle mode or inactive mode.

Abstract: A base station may restrict access by a user equipment (UE). The base station broadcasts access restrictions to one or more UE within a cell coverage area of the base station, wherein the access restrictions include one or more predetermined criteria that must be satisfied for a UE to be allowed to camp on the base station. The base station performs a random access channel (RACH) procedure to allow the UE to camp on the base station when the UE satisfies the one or more predetermined criteria.

Abstract: Apparatuses, systems, and methods for CCA power signaling during COT sharing. A UE may report a maximum EIRP for COT sharing as a UE capability, e.g., for a frequency range between 52.6 and 71 gigahertz. The UE may receive a Pout value for CCA based on the UE capability and may report an actual EIRP used for CCA to acquire the COT. For configured grant COT sharing, the UE may perform a directional LBT with a specific EIRP and beam detection for a transmission burst and report a Pout value for COT sharing based on the directional LBT, e.g., via a configured grant uplink control indication. For dynamic grant COT sharing, the UE may detect that an EIRP exceeds a threshold and report a Pout value for COT sharing via a medium access control (MAC) control element. The threshold may be based on a closed loop power control setting.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for providing a user equipment (UE) with on-demand reference signals for location related measurements of the UE. The UE can receive location assistance data from a network server, where the location assistance data includes information about a plurality of downlink reference signals that can be used to perform location related measurements by the UE. The UE can send a request to a base station for a reference signal. The reference signal is selected from the plurality of downlink reference signals of the location assistance data. Furthermore, the UE can receive the reference signal from the base station, and perform a location related measurement based on the received reference signal.
