Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a first slot for a semi persistent scheduled (SPS) transmission on a first serving cell of multiple serving cells in a physical uplink control channel (PUCCH) group. The UE may be configured to transmit feedback information for the SPS transmission in a target slot. The UE may select either the target slot or a subsequent second slot for transmission of the feedback information based on an availability of uplink resources on the multiple serving cells in the target slot. The UE may transmit the feedback information to a base station in the target slot or the subsequent second slot based on the selection. The described techniques may enable the UE to transmit the feedback information with reduced latency, among other benefits.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a network device, a trigger command initiating a hash-based random access procedure. The trigger command includes a target hash value and one or more rules for selecting preambles. The method also includes selecting, based on the trigger command, one or more random access channel (RACH) occasions (RO) for potential preamble transmission. The method further includes calculating at least one hash value in response to the trigger command based on computational resources of the UE. The method also includes transmitting a preamble on the at least one selected RO based on the at least one hash value and the target hash value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a first message that indicates a sidelink bandwidth part (BWP) switch, for the second UE, to a first sidelink BWP, where the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The first UE may transmit, to the second UE, a second message that confirms the sidelink BWP switch for the second UE. The first UE may receive, from the second UE, a third message that activates the sidelink BWP switch, for the second UE, to the first sidelink BWP. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a base station or reader) may transmit an initial access trigger message (e.g., modulating a continuous wave transmission using amplitude shift keying (ASK)), and the trigger message may include an indication of a type of passive user equipment (PUE) or a PUE use case (e.g., high priority/latency-critical PUEs or low priority/latency non-critical PUEs). A receiving PUE may harvest energy from the initial access trigger message for transmitting an initial access response message including an identifier for the receiving PUE. The receiving PUE may transmit the initial access response message (e.g., on one or more initial access resources) using the harvested energy if the trigger message indicates the PUE's type of PUE or PUE use case. In some examples, the receiving PUE may ignore triggers for different types of PUEs or PUE use cases.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a nominal time domain window duration and at least one of a quantity of nominal time domain windows or a quantity of actual time domain windows for demodulation reference signal bundling. The UE may calculate, in accordance with the quantity of nominal time domain windows being a single nominal time domain window or the quantity of actual time domain windows being a single actual time domain window, and in accordance with an indication that antenna switching is enabled, an adjusted nominal time domain window duration in accordance with applying a parameter to the nominal time domain window duration. The UE may calculate an adjusted quantity of nominal time domain windows and may identify a plurality of actual time domain windows. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a first cell, a physical downlink control channel (PDCCH) order, wherein the PDCCH order includes an indication identifying a second cell to which the PDCCH order applies, wherein the second cell is different from the first cell, and wherein the PDCCH order triggers a random access procedure associated with the second cell. The UE may perform the random access procedure associated with the second cell based at least in part on the PDCCH order. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, timing of a PRS instance is determined, and timing of a PO is determined based at least in part upon the timing of the PRS instance. UE transitions from DRX OFF state to DRX ON state and receives/measures the PO and PRS resource(s) of the PRS instance (e.g., without returning to DRX OFF state or sleep state until both the PO and PRS resource(s) are received/measured).
