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, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.

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.

Abstract: In an aspect, a wireless node (e.g., UE or BS) measures, at a first hop of a frequency hopping scheme, a reference signal (RS) on a first sub-band of an effective RS bandwidth, and measures, at a second hop of the frequency hopping scheme, the RS on a second sub-band of the effective RS bandwidth, the first and second sub-bands of the effective RS bandwidth overlapping in part. In another aspect, a UE transmits, at a first hop of a frequency hopping scheme, a reference signal (RS) on a first sub-band of an effective RS bandwidth, and transmits, at a second hop of the frequency hopping scheme, the RS on a second sub-band of the effective RS bandwidth, the first and second sub-bands of the effective RS bandwidth overlapping in part.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may determine wide beam parameters for beamformed communications with a base station based on an identified narrow beam. A UE may receive a reference signal from a base station and identify a narrow beam based on measurements of the received reference signal. Based on the identified narrow beam, the UE may determine a set of wide beam parameters for a wide beam that is to be used for communications between the UE and the base station. The wide beam may have a beam direction that corresponds to a direction of the identified narrow beam, and may have a beam width that is determined as a multiple of a beam width of the identified narrow beam (e.g., x times the beam width of the narrow beam).
