Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may transmit a downlink pre-emption indication (DLPI) or an uplink cancellation indication (ULCI) to a user equipment (UE) to indicate that a subset of resources of a scheduled downlink or uplink data transmission have been pre-empted or canceled. As such, the UE may either empty a buffer at the UE associated with the subset of resources or refrain from transmitting over the subset of resources based on receiving the DLPI or the ULCI, respectively. In some aspects of the present disclosure, the UE and the base station may support one or more inter-UE multiplexing schemes to increase a likelihood for the UE to receive the DLPI or the ULCI or to otherwise avoid collisions with communications between the base station and one or more other UEs.

Abstract: Certain aspects of the present disclosure provide techniques for enhancements made to uplink cancellation indications (ULCIs) for specific user equipment (UE) types (e.g., a reduced capability (RedCap) UE). An example method by a user UE generally includes receiving an UL CI indicating resources on which one or more uplink transmissions are to be modified by the UE, and processing the ULCI in accordance with a first set of one or more parameters for ULCI processing specific to UEs of a first type.

Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a frequency domain resource allocation (FDRA) field in downlink control information for a transport block that is sized over multiple repetitions. The UE may reinterpret bits in the FDRA field, which indicate an allocated quantity of physical resource blocks (PRBs) greater than an allocation threshold, to determine that a PRB of the transport block for uplink transmission is a sub-PRB communication. The UE may transmit the sub-PRB communication based at least in part on reinterpreting the bits in the FDRA field. Numerous other aspects are provided.

Abstract: Methods, systems (100), and devices for wireless communications are described. In some systems (100), a base station (105) and a user equipment (UE) (115) may communicate over a shared radio frequency spectrum and may employ time-division multiplexing (TDM) techniques to multiplex sensing signals (315) with wireless communications in the shared radio frequency spectrum. In some examples, the base station (105) may configure the UE (115) with a first retuning gap during which the UE (115) may retune a radio frequency chain of the UE (115) when transitioning from a sensing signal (315) pulse to wireless communications and with a second retuning gap during which the UE may retune the radio frequency chain when transitioning from wireless communications to a sensing signal (315). In some other examples, the base station (105) may configure the UE (115) with a phase and amplitude continuity status of multiple adjacent sensing signal (315) pulses that may indicate whether the multiple adjacent sensing signal (315) pulses have

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 message that indicates a preferred beam and a multicast session. The UE may receive, from the base station, a second message that indicates an association between a wakeup signal (WUS) and the multicast session, and a set of beams for receiving the WUS, the set of beams including the preferred beam. The UE may receive, from the base station and based at least in part on the second message, the WUS for the multicast session using a beam from the set of beams. Numerous other aspects are provided.
