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.

Abstract: A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

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.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

Abstract: A user equipment (UE) is configured to change a transmission configuration indicator (TCI) state. The receives, from the base station, a network flag indicating a transmission configuration indicator (TCI) state change configuration for the network, determines a time span for continuing to use a current TCI state prior to switching to a new TCI state based on the network flag and switches to the new TCI state after the time span.
