Abstract: This disclosure provides systems, methods and apparatus, for measurement and reporting procedures associated with a sidelink positioning reference signal (SL-PRS). In one aspect, a first user equipment (UE), which may function as a sidelink anchor node, may transmit an SL-PRS to a second UE in accordance with a slot format or structure that is dedicated for SL-PRS transmissions. The first UE may select resources for the transmission of the SL-PRS via sensing and exclusion or using a set of resources that are dedicated for SL-PRS transmissions. The second UE may receive the SL-PRS and use the SL-PRS to acquire positioning information, in accordance with an observed time difference of arrival (OTDOA)-based positioning method, or may transmit a second SL-PRS to the first UE to facilitate acquisition of positioning information at the first UE, in accordance with a round-trip-time (RTT)-based positioning method.

Abstract: Methods, systems, and devices for transmitting a positioning reference signal over a channel within a window including a set of positioning reference signal transmission opportunities. A device may identify the window and perform a channel access procedure to access the channel during the window. Based on performing the channel access procedure, the device may obtain access to the channel and determine that a portion of the positioning reference signal transmission opportunities are remaining within the window. The device may transmit a positioning reference signal during one or more of the remaining positioning reference signal transmission opportunities. In some cases, the device may refrain from transmitting a positioning reference signal during a portion of a positioning reference signal transmission opportunity even if the device gains access to the channel during that portion of the positioning reference signal transmission opportunity.

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.
