Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, a UE may support carrier aggregation in a high speed mode, such FR1 CA in HST. Serving cells can be particularly configured for the carrier aggregation based on the UE's capability to support carrier aggregation in the high speed mode. Additionally or alternatively, an SCell activation procedure can be performed based on this capability.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the up to beta*L*Mv entries in the combinational coefficient matrix W2 per layer, and the frequency basis selection matrix Wf to the base station.

Abstract: Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values Preserve,rs-ev (and optionally period definition data Kre-ev). Restrictions on the use of random resource selection by the UE are also described.

Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network to correlate resource selection with shared spectrum channel access. The device can perform a resource selection procedures within a resource selection window (RSW) to determine a set of candidate resources, and a clear channel assessment (CCA). A resource selection of one or more resources can be performed from the set of candidate resources to enable a sidelink (SL) communication. The CCA initiates after an aperiodic traffic arrival, after a previous transmission, or after the resource selection is completed.

Abstract: Systems and methods for performing measurements of one or more cells during an small data transmission (SDT) procedure between a user equipment (UE) and a network when the UE is in a radio resource control (RRC) INACTIVE state are described herein. Beam and/or cell measurements taken during an SDT measurement period of the SDT procedure may be used to determine one or more respective cell qualities, among other possibilities. Beginnings and endings of the SDT measurement period, and the manner (timing) for taking measurements within the SDT measurement period, are also described. The cell qualities so determined can then be used to monitor, during the SDT measurement period, for a measurement event, which causes the UE to send a measurement report to the network having data determined using those cell qualities, and/or to send messaging intended to induce the network to change the RRC state of the UE.

Abstract: This disclosure relates to techniques for configuring 8 transmit antenna uplink operation in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may perform sounding reference signal transmissions on each of 8 sounding reference signal resources, where each resource is associated with a transmit antenna port. The wireless device may receive an indication from the cellular base station of an 8 transmit antenna port uplink configuration to use, which may include a sounding reference signal resource indicator. The wireless device may perform uplink communication with the cellular base station using the 8 transmit antenna port configuration.

Abstract: Apparatuses, systems, and methods for positioning reference signals (PRSs) for reduced capacity devices, e.g., in 5G NR systems and beyond. A UE may be configured to receive, from a network (e.g., from a base station and/or an LMF), a first repetition of a frequency hopping (FH) PRS in a first frequency bandwidth. The first frequency bandwidth may be a subset of a full bandwidth used for full bandwidth PRSs. The UE may be configured to switch to a second frequency bandwidth that may be overlapped with the first frequency bandwidth. The second frequency bandwidth may be a subset of the full bandwidth. Additionally, the UE may be configured to receive a second repetition of the FH PRS in the second frequency bandwidth.
