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: A base station or other network component (next generation NodeB (gNB)) can operate to transmit a channel state information reference signal (CSI-RS) for channel state information (CSI) feedback. The CSI feedback can be received as corresponding to one or more frequency parts at hierarchical precoding levels of a frequency band based on a hierarchical precoding scheme in response to providing the CSI-RS.

Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.

Abstract: A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises a processor configured to receive a first downlink control information (DCI) for scheduling a first physical downlink shared channel (PDSCH). The first DCI includes a non-numerical (NN) value of K1 for hybrid automatic repeat request (HARQ)-ACK feedback. The processor is further configured to determine a first priority class associated with the first PDSCH, and determine K1 value and priority class associated with one or more subsequent PDSCH received from the BS, until a selected PDSCH having a numerical K1 value and a same priority class as the first priority class is identified. Further, the processor is configured to provide HARQ-ACK feedback associated with the first PDSCH using a PUCCH/PUSCH occasion indicated by a second DCI scheduling the selected PDSCH.

Abstract: A technique for wireless communications in a wireless system including: transmitting, from a second user device, unlicensed frequency transmission capability information, receiving an uplink transmission time for the second user device based on the unlicensed frequency transmission capability, receiving, at the second user device, a request to transmit a reservation transmission in an unlicensed frequency band based on a cancellation time capability of a first user device and the uplink transmission time, transmitting, by the second user device, the reservation transmission in the unlicensed frequency band, and transmitting, by the second user device, a higher priority uplink transmission in the unlicensed frequency band.

Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A UE can be polled by receiving a DCI that indicates dynamically updated resources. UE can be configured to find the DCI and use the resources to send a scheduling request (SR). Other aspects are described.

Abstract: A base station that determines a slot for uplink reception for a non-terrestrial network link between a base station and a user equipment is described. In exemplary embodiments, the base station determines a timing advance based on at least a random access preamble reception and determines an uplink offset based on the timing advance. The base station may further determine a candidate slot for an uplink reception based on at least the offset. In addition, the base station may determine if the candidate slot is available for the uplink reception. The base station may use the candidate slot for the uplink reception when the candidate uplink slot is available and may use the next available slot for the uplink reception when the candidate uplink slot is not available.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform closed-loop transmission power control in a multi-base station environment with out-of-order scheduling. The network may configure a series of transmission power control commands to indicate to the UE transmission power for one or more transmissions to different base stations. The UE may receive the transmission power control commands, consider information including timing and/or resources associated with the transmission power control commands, and determine transmission power for the transmissions.
