Abstract: Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method for wireless communication by a user equipment (UE) includes receiving a positioning reference signal in a time slot, wherein the positioning reference signal spans a first frequency bandwidth, transmitting a signal in a second frequency bandwidth during the time slot, wherein the second frequency bandwidth includes frequencies within the first frequency bandwidth, and processing the positioning reference signal received in the first frequency bandwidth excluding the frequencies in the second frequency bandwidth.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a switching rule pertaining to either carrier switching or antenna switching associated with the UE performing a reference signal transmission scheduled on a second carrier. The UE may receive a grant scheduling a downlink data transmission on a first carrier, the downlink data transmission comprising a priority level satisfying a priority threshold. The UE may determine that the reference signal transmission is scheduled on the second carrier within a time threshold of the downlink data transmission on the first carrier. The UE may monitor for the downlink data transmission instead of performing the reference signal transmission based at least in part on the switching rule and the priority level of the downlink data transmission satisfying the priority threshold.

Abstract: Certain aspects of the present disclosure provide techniques for channel estimation for two-stage sidelink control using sidelink data channel demodulation reference signals (DMRS). A user equipment (UE) can transmit DMRS for the sidelink data channel. The UE may transmit the second stage of the sidelink control using antenna ports or a precoder used for the sidelink data channel. The receiving device may receive the DMRS, estimate the channel, and demodulate the second stage of the sidelink control based on the estimated channel. The receiving device may flexibly determine the DMRS to use for the estimation and demodulation.

Abstract: In some implementations, a server may obtain metric information from each of a group of RF positioning anchors, wherein the metric information of a respective RF positioning anchor comprises information regarding: a time source accessible to the respective RF positioning anchor, a ground truth accuracy of a known location of the respective RF positioning anchor, a clock stability of the respective RF positioning anchor, a geographic location of the respective RF positioning anchor, a prevalence of Line of Sight (LoS) links of the respective RF positioning anchor, or power consumption information of the respective RF positioning anchor, or a combination thereof. The server may select the synchronization reference anchor from the group of RF positioning anchors based at least in part on the metric information. The server may transmit information indicative of the selected synchronization reference anchor to each RF positioning anchor of the group of RF positioning anchors.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration indicating one or more PRS resources transmitted on one or more antenna ports of at least one antenna panel of a base station, measures the one or more PRS resources over a set of angles, wherein the UE is configured to search for the one or more PRS resources over the set of angles based on the PRS configuration, and determines an angle of the set of angles over which at least one PRS resource of the one or more PRS resources was measured as a downlink angle-of-departure (DL-AoD) between the base station and the UE.

Abstract: In some scenarios, SRS transmission over the full SRS bandwidth may be unnecessary and/or inefficient. Therefore, a need exists for approaches to SRS transmission over less than the full SRS bandwidth. Described herein are techniques and solutions of SRS transmission using only a portion of the full SRS bandwidth, or a partial SRS bandwidth. The present disclosure provides for SRS transmission using a partial SRS bandwidth through sounding patterns that use only the partial SRS bandwidth and/or using a partial SRS bandwidth through various SRS sequence generation configured for the partial SRS bandwidth. An apparatus receives an SRS configuration indicating a full SRS bandwidth; determines a frequency hopping pattern for SRS transmission based on the SRS configuration, and the frequency hopping pattern is limited to a partial SRS bandwidth less than the full SRS bandwidth; and transmits the SRS transmission to the base station based on the frequency hopping pattern.

Abstract: Aspects relate to wireless communication using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment with two or more active BWPs. The user equipment may then use one or more of the active BWPS at a time. For example, the user equipment may use multiple active BWPs for full-duplex communication. Alternatively or in addition, the user equipment may switch between active BWPs taking advantage of the extremely low switching time (e.g., at or near zero seconds) between active BWPs.
