Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, via one or more component carriers, one or more downlink reference signals from one or more serving or neighboring transmission-reception points (TRPs), wherein a number of the received one or more downlink reference signals is less than or equal to a maximum number of downlink path loss estimates, spatial transmit beam determinations, spatial receive beam determinations, or any combination thereof to be simultaneously maintained by the UE for positioning purposes, and wherein the maximum number does not include any downlink reference signals the UE is already monitoring for other purposes, and performs a downlink path loss estimate, a spatial transmit beam determination, a spatial receive beam determination, or any combination thereof at least based on each of the received one or more downlink reference signals.

Abstract: Disclosed are various techniques for wireless communication, and in particular, carrier-phase based positioning. In an aspect, a position estimation entity may obtain a first differential measurement based on measurement of a first set of positioning reference signal (PRS) resources by a first node and measurement of a second set of PRS resources by a second node, wherein the first set of PRS resources are phase-coherent with the second set of PRS resources. The position estimation entity may obtain a second differential measurement based on measurement of a third set of PRS resources by the first node and measurement of a fourth set of PRS resources by the second node, wherein the third set of PRS resources are phase-coherent with the fourth set of PRS resources. The position estimation entity may determine a positioning estimate of a target node based on the first differential measurement and the second differential measurement.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support closed-loop transmit power control (TPC) for user equipment (UE) sidelink communications. TPC information may be provided, by a first UE receiving transmissions from a second UE, with respect to a sidelink implemented between the UEs. TPC information may be multiplexed with sidelink data traffic in a sidelink communication between UEs. The TPC information may include a TPC indicator and one or more TPC messages for providing TPC commands with respect to one or more sidelinks. The sidelink data traffic of some examples may include data-only traffic, such as semi-persistent scheduled (SPS) data traffic, that is decoupled from accompanying sidelink control information (SCI). Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for sending a configuration for conditional configured grant (CG) occasions for uplink transmission to a user equipment (UE). Each conditional CG occasion may be associated with multiple conditional CG resources. Each conditional CG resource may be associated with a sending window. The UE may monitor within sensing windows for conditional CG resources of a certain conditional CG occasion for over the air (OTA) signals from other UEs to determine if the conditional CG resources are available for uplink transmission. The UE may skip the conditional CG occasion when the conditional CG resources are not available. The UE may perform uplink transmission on the conditional CG resources when the conditional CG resources are available.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode receives a DRX configuration, receives a reference signal resource configuration, determines, at least based on the DRX configuration and the reference signal resource configuration, whether an overlap exists between a reference signal occasion of a plurality of reference signal occasions of the reference signal resource configuration and an active time of the DRX configuration, receives or transmits at least based on a determined overlap, at least a first reference signal in the reference signal occasion, and receives or transmits, while remaining in an active state of the DRX configuration, at least based on the determined overlap, at least a second reference signal in remaining reference signal occasions of the plurality of reference signal occasions after expiration of the active time.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message which schedules a sidelink transmission from the first UE to a second UE on a first set of resources associated with a sidelink shared channel. The first UE may additionally receive a second DCI which indicates a second set of resources which are cancelled from the first set of resources. Based on the cancellation indication, the first UE may modify or cancel at least a portion of the sidelink transmission originally scheduled for the second UE, and may transmit the modified sidelink transmission over a portion of the first set of resources in accordance with the cancellation indication, the first DCI, and the second DCI.

Abstract: Certain aspects of the present disclosure provide techniques for switching control beams in multi-link systems using new radio (NR) technology multiple-input multiple-output (MIMO) techniques. A user equipment (UE) may obtain a configuration from a base station (BS) comprising at least one first pattern of beams to monitor when performing a beam recovery procedure, communicate using beamforming, with the BS, via an active transmit and receive beam pair, determine a beam failure of the active transmit and receive beam pair, and monitor the beams according to the first pattern in response to the beam failure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may alter, or otherwise cancel, a sidelink communication as a result of a cancelation indicator (CI) corresponding to a different UE to support automatic gain control (AGC) calibration. The UE may determine to cancel or alter sidelink resources that at least partially overlap in time and are adjacent to, yet non-overlapping, in frequency to a high priority transmission. In some implementations, the UE may cancel the sidelink communication from an earliest overlapping symbol to the end of a slot. In other implementations, the UE may cancel a portion of the sidelink communication and resume sidelink communications within the same slot. Additionally or alternatively, the UE may utilize one or more reference signals or symbols to enable AGC recalibration during the slot.
