    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: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP. The UE may determine RACH information related to the second TRP, based at least partly on the specified DL TCI related to the second TRP included in the handover command and the DL TCI list. The UE may then perform random access to the second TRP based on the RACH information related to the second TRP. The RACH information may include uplink (UL) beam information, RO information and Bandwidth Part (BWP) information for the UE to perform random access to the second TRP.

    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).

    Abstract: A user equipment (UE) configured to perform uplink power control. The UE determines that a first uplink transmission is scheduled to overlap in time with a second uplink transmission based on a look ahead window, determines a first transmission power for the first uplink transmission, determines a second transmission power for the second uplink transmission based on the first transmission power for the first uplink transmission and performs the first uplink transmission and the second uplink transmission.

    Abstract: The exemplary embodiments relate to user equipment (UE) monitoring one or more downlink reference signals for uplink power control. The UE may receive an indication that a downlink reference signal is assigned to the UE for a first operation. The first operation is uplink power control for an uplink signal. The UE then determines whether the UE is configured to monitor the downlink reference signal for a second different operation. When the UE is configured to monitor the downlink reference signal for the second different operation, the UE configures the downlink reference signal to be a pathloss reference signal that is to be used for the first operation.
