Abstract: A user equipment including a transceiver and a processor is disclosed. The processor is configured to receive from another UE a first sidelink control information (SCI) format payload identifying a number of resources reserved for transmission by the other UE. The processor is configured to detect, based on the received first SCI format and one or more resources selected by the UE for transmission, resource collision corresponding to one or more resources of the number of resources reserved for transmission by the other UE. The processor is configured to send, in response to the detected resource collision, a physical sidelink feedback channel (PSFCH) to the other UE for inter-UE coordination (IUC) of the number of resources reserved for transmission by the other UE.

Abstract: Some embodiments include an apparatus, method, and computer program product for implementing Channel State information (CSI) feedback for multi-Physical Downlink Shared Channel (PDSCH) transmissions in a wireless communication system. Some embodiments enable a user equipment (UE) to determine Channel Quality Indicators (CQI) and/or Precoding Matrix Indicators (PMI) for multi-PDSCH transmissions that account for effects of a duration of the multi-PDSCH transmission including the maximum interval between the first and last PDSCH transmissions on the CQI and PMI determinations. Some embodiments include a base station that detects a need for a change in a beam direction and adjusts the beam direction accordingly based on the PMI determinations. Some embodiments enable a desired hybrid automatic repeat request (HARQ)-ACK feedback transmission from a single multi-PDSCH transmission. Some embodiments include performing HARQ bundling with an update to the Type 1 HARQ-ACK codebook based on the multi-PDSCH transmission.

Abstract: Apparatus and methods are provided for CSI enhancement for multi-TRP coherent joint transmission. A user equipment (UE) receives signals from a plurality of transmission and reception points (TRPs). The UE determines, based on the signals, multiple TRP (multi-TRP) coherent joint transmission (CJT) channel state information (CSI) report information for a codebook based on a spatial basis selection matrix, a combination coefficient matrix, and a frequency basis selection matrix. The spatial basis selection matrix is layer common, polarization common, and TRP independent. The UE reports, to one or more of the plurality of TRPs, the multi-TRP CJT CSI report information.

Abstract: This disclosure relates to techniques for performing wireless communications including determination of actual time windows for maintaining power consistency and/or phase continuity associated with transmission between a user equipment (UE) and a base station. Techniques for determining the length, begging, and end of such windows are disclosed. A UE and/or base station may use various rules to determine the window(s).

Abstract: Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions. Finally, the UE may use (or maintain) the same transmission power, for each TTI transmit occasion of the same TTI bundle in order to improve (cross-slot) channel estimation accuracy. Power allocation may be prioritized to ensure that at the same time a total power for the uplink transmissions of the UE does not exceed a specified threshold.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a vehicle-to-everything (V2X) capable wireless device configured to perform sidelink cellular communications. The wireless device performs sidelink communications using a two-stage sidelink control information (SCI) protocol including Stage 1 SCI messaging carried on a physical sidelink control channel (PSCCH), and Stage 2 SCI messaging carried on a physical sidelink shared channel (PSSCH). The SCI messaging may be encoded using polar codes. Channel interleaving is utilized on the SCI to interleave the SCI between two or more layers of a MIMO transmission system. Scrambling for Stage 2 SCI messaging is performed based on the result of a cyclic redundancy check (CRC) performed on Stage 1 SCI messaging. Collisions between sidelink HARQ feedback to be transmitted to a base station and other transmissions are avoided based on a priority analysis of the sidelink HARQ feedback.

Abstract: A base station may transmit beam indication information to one or more user equipment (UE) devices. For each of a plurality of time units (e.g., symbols) in a time interval (e.g., spanning one or more slots), the beam indication information indicates a corresponding beam that the base station will use to transmit or receive. A UE device may have knowledge of the beam in which it currently resides, e.g., by performing power measurements during a beam scan procedure. Thus, the beam indication information enables the UE to perform transmissions and/or receptions (e.g., configured transmissions and/or receptions) during the appropriate time unit(s). The beam indication information may be dynamically transmitted as part of downlink control information. This transmission may omni-directional, wide beam, or narrow beam. Various schemes of encoding the beam indication information are contemplated.
