Abstract: A user equipment (UE) is configured to handle physical downlink shared channel (PDSCH) transmissions during multi-transmission/reception point (TRP) operation. The UE receives a physical downlink control channel (PDCCH) transmission configured with downlink control information (DCI) in a single-DCI, multi-transmission/reception point (TRP) operation, wherein the DCI schedules reception of a physical downlink shared channel (PDSCH) transmission, determines whether or not a TCI field is configured in the DCI, when the TCI field is not configured in the DCI, determining a default beam based on a control resource set (CORESET) with the lowest ID in the PDCCH and when the TCI field is configured in the DCI, determining whether the TCI field indicates a TCI codepoint includes two TCI states.

Abstract: Improved solutions for reliable physical channel, e.g. Physical Downlink Shared Channel (PDSCH) reception during wireless communications, for example during 3GPP New Radio (NR) communications include continuous channel repetitions that cross slot boundaries, channel repetitions with multiple frequency hops, and joint-repetition channel estimation that uses demodulation reference signals from at least two channel repetitions for the channel estimation. In one aspect, reliable PDSCH reception may have the benefit of aiding target UEs and serving base stations in implementing reliable Multicast and Broadcast Services (MBS).

Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

Abstract: Technology is provided for supporting different numerologies for concurrent intra-frequency measurements and downlink data reception. A user equipment (UE) may send a message to the a wireless network to indicate whether the UE supports a mixed numerology wherein a different subcarrier spacing (SCS) is used in a serving cell or a neighboring cell for concurrent processing of at least two of: intra-frequency measurement by the UE of a synchronization signal block (SSB); intra-frequency measurement by the UE of a channel state information reference signal (CSI-RS) for mobility; and reception by the UE of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH). Based on the indication, the network may configure at least one of a CSI-RS measurement expectation, an SSB measurement expectation, and a scheduling restriction for reception of the PDCCH or the PDSCH by the UE.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. In one example, a user equipment (UE), includes a memory and one or more processors configured to, when executing instructions stored in the memory, cause the UE to determine a SCI stage 2 scrambling initialization value (Cinit) based on at least a portion of a physical sidelink control channel (PSCCH) cyclic redundancy check (CRC) code and a resource pool constant NCONST_RP, wherein NCONST_RP is configured for a resource pool allocated for sidelink communication by the UE; generate a scrambling sequence based on the SCI stage 2 Cinit; and transmit a SCI stage 2 to the second UE based on the scrambling sequence.

Abstract: Apparatuses, systems, and methods for user equipment device (UE) uplink antenna panel selection. The UE may determine, based on at least one condition, to perform a beam switch from a current beam being used for communications with a base station. The UE may transmit, to the base station, an indication of an antenna panel status that may include an indication of a latency associated with the beam switch. The UE may receive, from the base station, an indication to switch to a target beam and to perform the switch, based on the indication, to the target beam. The indication of the antenna panel status may include a beam switching latency level for each beam in a beam report, a beam switch request that may indicate the target beam, and/or a beam switch request that may indicate that an antenna panel switch is to be applied by the UE.

Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.
