Abstract: A user equipment (UE) is configured to receive a synchronization signal block (SSB) transmission with a first subcarrier spacing (SCS) in an SSB burst window (SSBW), decode the SSB transmission to determine parameters for a control resource set 0 (CORESET #0) to be transmitted in the SSBW using a second SCS that is different from the first SCS, monitor physical downlink control channel (PDCCH) candidates in the determined CORESET #0 based on a mapping between the SSB transmission and the CORESET #0 and decode the PDCCH and a system information block 1 (SIB1) scheduled by the PDCCH in the SSBW.

Abstract: A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).

Abstract: Embodiments of the present disclosure relate to uplink transmission with repetitions. 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 first Channel State Information (CSI) and second CSI based on at least one of a previous channel and interference measurement or a latest channel and interference measurement. The operations further comprise transmitting the first CSI via the transceiver to the network with a first beam, the first CSI multiplexed with a first repetition of an uplink transmission with the first beam. The operations further comprise transmitting the second CSI via the transceiver to the network with a second beam, the second CSI multiplexed with a second repetition of the uplink transmission with the second beam.

Abstract: A base station configures a user equipment (UE) to perform measurements. The base station configures the UE for a channel state information (CSI) measurement report comprising layer 1 (L1) measurement values for one or more reference signals (RS) transmitted from a neighbor base station, wherein the CSI measurement report configuration includes an indication of one or more parameters for each of the RS to be measured from the neighbor base station and receives the CSI measurement report comprising the L1 measurement values for the neighbor base station.

Abstract: Mechanisms are provided for a user equipment (UE) to determine a transmission frequency or a time advance for an uplink transmission from the UE to a base station in a non-terrestrial wireless network (NTN) without global navigation satellite systems (GNSS) information available to the UE. A communication connection between the UE and a base station can be established. The UE can determine that GNSS information is not available, and report to the base station that the GNSS information is not available. The UE can receive, from the base station, an indication of one or more parameters for an uplink transmission from the UE to synchronize the uplink transmission. The UE can determine, based on a current transmission frequency and the received indication of the one or more parameters, a next transmission frequency and transmit the uplink transmission at the determined next transmission frequency.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig indicates up to L CSI reference signal (CSI-RS) ports for selection by the UE out of P CSI-RS ports configured for measuring and reporting CSI. The UE determines selected CSI-RS ports out of the P CSI-RS ports. The selected CSI-RS ports include the L CSI-RS ports or less. The UE generates a port selection matrix W1 corresponding to the selected CSI-RS ports. The UE also generates an indication of the port selection matrix W1 to the base station. The CSI-ReportConfig may further configure the UE to select a subset of frequency basis. The UE determines a selected subset of frequency basis and generates a frequency basis selection matrix Wf corresponding to the selected subset of frequency basis.
