Abstract: A user equipment may use a soft acknowledgment/negative-acknowledgement (ACK/NACK) report to indicate a number of desired repetitions for Physical Downlink Shared Channel (PDSCH). In some embodiments, the user equipment may generate a soft ACK/NACK report that includes multiple bits. The multiple bits may be coded to indicate to a network node whether an allocated number of repetitions was sufficient, redundant or insufficient, and how many more repetitions are needed or desire by the UE.

Abstract: A user equipment (UE) may receive a measurement reporting capability request from a base station and further transmit, in response to the request, an indication of the UE’s measurement reporting capability. The UE may further receive, signaling comprising a channel status information (CSI) request trigger from the base station. In response to receiving the CSI request trigger, the UE may transmit a measurement report to the base station, wherein the measurement report may comprise at least one received signal strength indicator (RSSI) measurement.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: In an example method, a user equipment (UE) device receives, from one or more base stations (BSes), Downlink Control Information (DCI) including scheduling information for receiving a plurality of Physical Downlink Shared Channels (PDSCHs) from the BSes. The UE device determines a pre-determined time subsequent to a reception of a sequentially last symbol of the DCI, and determines (i) a first subset of the PDSCHs scheduled for reception prior the pre-determined time, and (ii) a second subset of the PDSCHs scheduled for reception subsequent to the pre-determined time. The UE device determines one or more Transmission Configuration Indicator (TCI) states that indicate a quasi co-location (QCL) for a plurality of antenna ports of the one or more PDSCHs that are transmitted by the BSes. Further, the UE device processes the first subset of the PDSCHs and the second subset of the PDSCHs according to the determined TCI states.
