    Abstract: In an aspect, a first and second wireless node communicate a bistatic sensing request and a response to the bistatic sensing request to coordinate setup of a bistatic sensing procedure. The first wireless node transmits a set of sensing signals to one or more target objects in accordance with the bistatic sensing procedure. The second wireless node measures a set of reflections of the set of sensing signals reflected off of one or more target objects in accordance with the bistatic sensing procedure.

    Abstract: Aspects relate to a user equipment that transmits an uplink transmission on a first receive beam of a first beam pair link and on a second receive beam of a second beam pair link. A base station receives the uplink transmission on a first transmit beam of the first beam pair link and a second transmit beam of the second beam pair link via first and second transmission and reception points associated with the base station. The base station transmits a downlink transmission on the first transmit beam with a first beam-specific timing precompensation and on the second transmit beam with a second beam-specific timing precompensation. The first beam-specific timing precompensation and the second beam-specific timing precompensation are based on a timing difference between the reception of the uplink transmission via the first TRP and via the second TRP. The user equipment receives the beam-specific timing precompensations.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that demodulation reference signal (DMRS) bundling is to be used for channel estimation by the base station for one or more physical uplink control channel (PUCCH) repetitions, where the indication is a semi-static configuration or a dynamic indication. The UE may transmit, to the base station, the one or more PUCCH repetitions by maintaining a phase continuity among DMRSs of the one or more PUCCH repetitions based at least in part on receiving the indication that DMRS bundling is to be used. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide techniques for determining when to transmit and transmitting an aperiodic tracking reference signal (TRS). Certain aspects provide a method for wireless communication. The method generally includes determining a channel condition change of a downlink channel between a first wireless device and a second wireless device. The method further includes determining whether the channel condition change satisfies a trigger condition. The method further includes triggering transmission of an aperiodic tracking reference signal when the channel condition change satisfies the trigger condition.

    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.
