    Abstract: A user equipment (UE) in a multiple transmission and reception point (multi-TRP) configuration having simultaneous connections with a first next generation node B (gNB) and at least one second gNB over a same carrier. The UE divides uplink (UL) resources into a plurality of groups, determines a spatial relation and a pathloss reference signal (RS) for each one of the plurality of groups based on a transmission configuration indication (TCI) indicating a quasi-co-location (QCL) source RS for a downlink channel and transmits UL data on the UL resources corresponding to each one of the plurality of groups to a respective one of the first gNB or the at least one second gNB.

    Abstract: Various user equipment (UE) operations performed when the UE is in multiple Downlink Control Information (multi-DCI) based multiple transmission and reception point (multi-TRP) configuration. The operations receiving, from one of the first or second gNBs, one or more cell reference signal (CRS) rate matching patterns, wherein the one or more CRS rate matching patterns comprise an indication of a control resource set (CORESET) pool for each of the one or more CRS rate matching patterns and applying the one or more CRS rate matching patterns to a CORESET for a Physical Downlink Shared Channel (PDSCH) based on the indication of the CORESET pool.

    Abstract: A user equipment (UE) is configured to transmit an uplink transmission with a bundling of demodulated reference signals (DMRS), transmit the uplink transmission, receive a downlink control information (DCI) transmission from the base station between repetitions of the uplink transmission, wherein the DCI indicates a transmission power control (TPC) information element (IE) indicating remaining ones of the repetitions of the uplink transmission should be transmitted using a new transmission power and determine if the DCI is a group common (GC)-DCI Format 2_2.

    Abstract: The present disclosure is directed to systems and methods for determining a starting point of a measurement gap. For example, the present disclosure is directed to a user equipment (UE) that includes a memory and processor circuitry coupled to the memory. The processor circuitry may be configured to receive an indication of a measurement gap timing advance. The processor circuitry may be further configured to, based on the indication of the measurement gap timing advance, determine a starting point of a measurement gap in a dual connectivity mode that provides dual connectivity with a new radio (NR) and an evolved universal mobile telecommunications system terrestrial radio access (EUTRA). The NR may serve as a master Radio Access Network (RAN) and the EUTRA may serve as a secondary RAN. The processor circuitry may also be configured to perform a signal quality measurement during the measurement gap, wherein the signal quality measurement is performed on a target cell of the NR or EUTRA.

    Abstract: Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.

    Abstract: A method and apparatus of a device that acquires transmission configuration indicator (TCI) information for secondary cell (SCell) activation. In some embodiments, the TCI information is acquired for SCell activation by determining, during secondary cell (SCell) activation, that beam information to enable a user equipment (UE) to make a reliable layer 1 (L1)-Reference Signal Received Power (RSRP) measurement report is unavailable, perform the L1-RSRP measurement using information of one or more Synchronization Signal Blocks (SSBs) during the SCell activation, wherein the one or more processors perform the L1-RSRP measurement using information of one or more SSBs during the SCell activation by identifying, by the UE, one or more detectable SSBs during the SCell activation and using information of the one or more detectable SSBs for the L1-RSRP measurement
