    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: The present disclosure relates to apparatus, methods, computer-readable storage medium and computer program product for high speed train measurements and signaling. A wireless device, comprising: at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio; wherein the processor is configured to: receive, via the at least one radio, at least one Radio Resource Control (RRC) signaling from a cellular base station, the at least one RRC signaling at least comprises one or more information element (IE) of a group of IEs, wherein, the group of IEs at least includes a first IE indicating to enable or disable enhancement on a Secondary Cell (SCell) in Frequency Range 2 (FR2), and a second IE indicating to enable or disable enhancement on a Primary Secondary Cell (PSCell); and perform enhancement on one or more corresponding cells in response to the received at least one RRC signaling, wherein, the enhancement comprises determining a reduced time period for Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS) detection and/or determining a reduced time period for intra-frequency measurements.

    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: Triggering an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX,f,c value, or a P value. Based on the power headroom value, the PCMAX,f,c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

    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.
