    Abstract: The present disclosure relates to apparatus, methods, computer-readable storage medium and computer program product for CSI-RS enhancement for Port Selection Codebook with Channel Reciprocity. A cellular base station, comprising: at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio; wherein the cellular base station is configured to: provide a Radio Resource Control (RRC) message to a wireless device; and provide a Channel State Information-Reference Signal (CSI-RS) to the wireless device via one or more ports based on the RRC message, wherein, the RRC message at least indicates one or more of: information on a density of the CSI-RS, information on time domain locations of the CSI-RS, information on a subset of ports for the wireless device to measure the CSI-RS, and information on a subset of Code Division Multiplexing (CDM) groups for the wireless device to measure the CSI-RS.

    Abstract: Embodiments of the present disclosure relate to uplink simultaneous transmission on multiple panels. According to embodiments of the present disclosure, a user equipment (UE) comprises a transceiver configured to communicate with a network; and a processor communicatively coupled to the transceiver and configured to perform operations. The operations comprise determining a UE assistance information for uplink (UL) Simultaneous Transmission on Multiple Panels (STxMP). The operations further comprise reporting the UE assistance information to the network device. The operations further comprise receiving a UL STxMP enabling indication from the network device. The operations further comprise performing UL STxMP with the network device when the received UL STxMP enabling indication indicates that UL STxMP is enabled.

    Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.

    Abstract: Systems and methods disclosed herein relate to confirmatory signaling sent by a base station for the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH) scheduled in downlink control information (DCI) sent by the base station. Confirmatory signaling may be provided in the form of DCI, or in the form of a physical confirmation indicator channel (PCICH). Confirmatory signaling in DCI may confirm multi-PUSCH/multi-PDSCH scheduling according to one or more UE, and according to one or more CC used by each of the one or more UE using a bitmap. Confirmatory signaling in PCICH may confirm the multi-PUSCH/multi-PDSCH scheduling according to one or more UE. In these embodiments, a symbol for each such UE is spread according to different orthogonal covering codes (OCC), and such spreaded symbols are sent to the UE in a resource element set (RES) of a physical radio block (PRB).
