    Abstract: Provided is a method for a user equipment (UE). The UE obtains a first control information from a network device. The first control information indicates a plurality of search space sets including a first search space set and a second search space set. The first search space set and the second search space set are linked. The first search space set includes a first physical downlink control channel (PDCCH) candidate for the first search space set and the second search space set includes a first PDCCH candidate for the second search space set. The first PDCCH candidate for the first search space set and the first PDCCH candidate for the second search space set are linked. The UE monitors PDCCH candidates based on the first control information.

    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: 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.
