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: Apparatuses, systems, and methods may determine a transport block size using a number of resource elements for sidelink data. The number of resource elements for the sidelink data is calculated based at least on a reference second stage Sidelink Control Information (SCI) overhead. The reference second stage SCI overhead is calculated using the reference coding rate, the reference beta offset, the reference PSFCH symbol number, the alpha value, and the second stage SCI payload size.

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: Systems, methods, and apparatuses for cross division duplex (XDD) operation in a wireless communication system are described herein. A user equipment (UE) is configured with one or more sub-bands (SBs) within a larger overall bandwidth (BW) (e.g., represented by a component carrier (CC), a bandwidth part (BWP), etc.), and that use uplink (UL)/downlink (DL) resource allocation(s) that may be different than the larger BW. Configurations for such SB-specific (SBS) arrangements that use guard bands (GBs) between SBs are discussed. Mechanisms for slot format indications (SFIs) within such SBs using either SBS DCI or cross-SB DCI are discussed. Mechanisms for providing SBS uplink resource for initial access (e.g., random access) using at least one initial UL BWP that is configured relative to one or more SBs and that may be used by XDD-capable UEs are discussed.

A wireless device may receive vehicle-to-everything resource pool configuration information and sidelink control information. A number of resource elements allocated for a vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the resource pool configuration information and the sidelink control information. A transport block size for the vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the number of resource elements allocated for the vehicle-to-everything physical sidelink shared channel. A low density parity check base graph may be selected for the vehicle-to-everything physical sidelink shared channel based at least in part on the determined transport block size.

Abstract: Apparatuses, systems, and methods for a wireless device to disable a HARQ feedback in either a semi-static way or in a dynamic way and to perform HARQ optimization. The wireless device may be configured to receive a first set and a second set of HARQ process numbers, where the first set and the second set of HARQ process numbers correspond to a first set and a second set of HARQ processes respectively, where each HARQ process in the first set of HARQ processes is configured to enable a HARQ feedback, and where each HARQ process in the second set of HARQ processes is configured to disable or enable a HARQ feedback. The wireless device may be configured to receive a grant configuration or a SPS, where the grant configuration or the SPS include a flag indicating whether a HARQ-based retransmission is disabled.
