Abstract: A method of wireless communication by a first sidelink user equipment (UE) transmits a sidelink (SL) beam failure recovery (BFR) message to a communications node, indicating a new candidate beam and an identifier (ID) of a second sidelink UE. The method also receives an acknowledgment of the SL BFR message. A communications node receives a sidelink beam failure recovery message from a first sidelink user equipment, indicating a new candidate beam and an ID of a second sidelink UE. The method also transmits information identifying the new candidate beam and the ID to the second sidelink UE. Another method by a first sidelink user equipment receives a sidelink beam failure recovery message from a base station, indicating a new candidate beam and an ID of a second sidelink UE. The method changes a beam used to communicate with the second sidelink UE in response to receiving the BFR message.

Abstract: Monostatic radar with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal for a first duration and receives a first reflection of the first signal from a first object during a second duration. The system transmits a second signal for a third duration longer than the first duration and receives a second reflection of the second signal from a second object during a fourth duration. The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects between the first distance and a second distance from the system.

Abstract: Aspects of the disclosure relate to a base station providing a user equipment (UE) with a sticky uplink beam assignment for one or more uplink signals. The UE may use the sticky uplink beam assignment for transmission of uplink signals until a new sticky uplink beam assignment is received. In some examples, the sticky uplink beam assignment may include an uplink beam identifier (ID) identifying an uplink beam associated with the transmission of an uplink signal. The uplink beam identified by the uplink beam ID may be used by the UE for transmission of the uplink signal and either all subsequent uplink signals (e.g., physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH)) or subsequent uplink signals of particular uplink channel types (e.g., dynamic PUSCH, configured grant (CG), PUCCH, etc.) until a new uplink beam ID is received. Other aspects, features, and examples are also claimed and described.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) measures at least a line-of-sight (LOS) path and a non-line-of-sight (NLOS) path of a first downlink positioning reference signal (DL-PRS) from a first transmission-reception point (TRP), measures at least an LOS path and an NLOS path of a second DL-PRS from a second TRP, measures at least an LOS path and an NLOS path of a third DL-PRS from a third TRP, and enables a location of a non-participating target object to be determined based, at least in part, on reference signal time difference (RSTD) measurements between a time of arrival (ToA) of the LOS path of the first DL-PRS and the ToAs of the NLOS paths of the first, second, and third DL-PRS. In an aspect, the non-participating target object does not participate in determining its own location.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, in a first paging occasion, paging information that identifies a data transmission in a second paging occasion subsequent to the first paging occasion; and receive the data transmission during the second paging occasion. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more physical downlink control channels (PDCCHs) indicating paging information for a paging message; and receive the paging message on one or more physical downlink shared channels (PDSCHs), wherein at least one of: one or more resources for the one or more PDCCHs, or one or more resources for the one or more PDSCHs, is configured so that cross-slot scheduling of paging and intra-slot scheduling of paging can occur during the same paging occasion. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first communication that includes information to facilitate selection and/or switching of carrier aggregation or multi-connectivity for a first cell group and a second cell group. The UE may receive, based at least in part on transmitting the first communication, a second communication that configures and/or switches carrier aggregation or multi-connectivity for the first cell group and the second cell group.

Abstract: Aspects described herein relate to communicating a demodulation reference signal (DMRS) corresponding to a downlink control channel, buffering, based on receiving the DMRS, samples of a downlink data channel associated with the downlink control channel, and processing, during on a time period indicated based at least in part on a sequence of the DMRS, at least a portion of the samples of the downlink data channel. Another aspect relates to determining, based at least in part on a sequence of the DMRS, a time offset from the downlink control channel to a downlink data channel, and determining, based at least in part on the time offset, a time period based on which to transmit or start processing samples of the downlink data channel.
