    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: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a second UE, and a processor communicatively coupled to the transceiver. The processor is configured to determine one or more channel state information (CSI) reporting elements out of a set of CSI reporting elements. The processor is further configured to generate a MAC control element (MAC-CE) message. The MAC-CE message comprises an indicator that indicates a second MAC-CE message and a CSI report. The CSI report comprises the one or more CSI reporting elements. The processor is further configured to transmit, using the transceiver, the MAC-CE message to the second UE via a side-link connection.

    Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a second UE, and a processor communicatively coupled to the transceiver. The processor is configured to determine a set of subcarriers from two physical resource blocks (PRBs). The set of subcarriers includes only one subcarrier or more than two subcarriers. The processor is further configured to transmit, using the first set of antenna ports of the transceiver, channel state information reference signals (CSI-RSs) in a set of resource elements (REs) to the second UE. The set of REs occupies the set of subcarriers.

    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: Some aspects of this disclosure relate to apparatuses and methods for implementing sidelink communications among multiple user equipments (UEs). A UE operates according to a periodical discontinuous reception (DRX) cycle that includes a sidelink on-duration period when the UE is in an active state. The UE is in a power saving state outside the sidelink on-duration period. The UE listens to a Physical Sidelink Control Channel (PSCCH) for sidelink communications during the active state. A UE determines the DRX cycle and the sidelink on-duration period of a receiver UE, and sends a message to the receiver UE during one or more slots of the sidelink on-duration period when the receiver UE is in the active state.
