Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first physical uplink shared channel (PUSCH) using one or more physical layer (PHY) parameters associated with a first block error rate (BLER) target performance. The UE may receive, from the base station prior to expiration of a round trip timer associated with the first PUSCH, downlink control information (DCI) scheduling a second PUSCH and configuring one or more PHY parameters associated with a second BLER target performance. The UE may transmit, to the base station, the second PUSCH using the PHY parameter(s) associated with the second BLER target performance, wherein the second PUSCH includes a retransmission of the first PUSCH or a new transmission based at least in part on a hybrid automatic repeat request process indicated in the DCI. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for reducing a size of semistatic codebooks for HARQ feedback. A method that may be performed by a user equipment (UE) includes determining a number (M) of candidate downlink transmission occasions for a time period, determining a maximum number (k) of simultaneous downlink transmissions the UE can receive during the time period, receiving one or more downlink transmissions during the time period from a base station, and determining a type of encoding for the HARQ feedback based on: (i) a number of the one or more downlink transmissions received, (ii) the number (M) of candidate downlink transmission occasions for the time period, and/or (iii) the maximum number (k) of simultaneous downlink transmissions.

Abstract: A method by a user equipment (UE) includes receiving at least one time offset for scheduling non-terrestrial communications. The at least one first time offset is configured according to a numerology and/or a bandwidth part (BWP). The UE communicates in accordance with the time offset(s). The time offset may be a single time offset that applies across all numerologies or may be multiple time offsets, each specific to a particular numerology or bandwidth part (BWP). The time offset may be a single time offset scaled based on a current numerology configured for communications. The time offset may apply across different bandwidth parts (BWPs) or across multiple component carriers from which the UE is receiving downlink data.

Abstract: Methods, systems, and devices for wireless communications are described. A second wireless device (such as a head-mounted display (HMD) device) may communicate with a first wireless device (such as a user equipment (UE)) via a tethered wireless connection. The tethered wireless connection may be associated with a first type of radio access technology (RAT). The first wireless device may obtain an indication of one or more access points (APs) associated with a second type of RAT. The first wireless device may transmit an indication of one or more candidate APs for a handover of the second wireless device from the first wireless device to maintain the connectivity between the second wireless device and a network. As such, the second wireless device may use the wireless characteristics to determine whether to handover to a candidate AP or maintain the tethered wireless connection with the first wireless device.
