Abstract: Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive. from a base station, signaling that indicates an indirect assignment of a slot for transmitting sounding reference signals (SRSs) in multiple SRS resource sets. The UE may determine whether the slot is available for the indirect assignment based on a first set of characteristics associated with the multiple SRS resource sets and a second set of characteristics associated with the slot. If the UE determines that the slot is available for the indirect assignment, the UE may transmit SRSs in the multiple SRS resource sets during the slot. If the UE determines that the slot is unavailable for the indirect assignment. the UE may refrain from transmitting SRSs in one or more of the multiple SRS resource sets during the slot.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) reports, to a network entity, a minimum number of symbols of a positioning reference signal (PRS) resource of a first transmission-reception point (TRP) of a pair of TRPs based on a reference signal time difference (RSTD) uncertainty parameter for the pair of TRPs, wherein the minimum number of symbols is less than a total number of symbols allocated for the PRS resource, and performs a positioning measurement of the minimum number of symbols of the PRS resource.

Abstract: In some aspects, a base station may transmit, to a user equipment (UE), an instruction that triggers the UE to transmit an uplink random access channel (RACH) message, the instruction identifying a RACH preamble index corresponding to a RACH preamble to be used for the uplink RACH message; transmit, to a plurality of neighbor base stations, information that identifies the RACH preamble index; receive the uplink RACH message from the UE; receive, from the plurality of neighbor base stations, feedback that indicates respective timings with which the uplink RACH message was received by the plurality of neighbor base stations; and estimate a position of the UE based at least in part on a timing with which the uplink RACH message was received by the base station and at least two of the respective timings with which the uplink RACH message was received by the plurality of neighbor base stations.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine that the UE is or will be at a location within a calibration region. The UE may report, to a network entity, location information, the location information being associated with the location within the calibration region. In an aspect, a network entity may obtain calibration error information associated with a user equipment (UE) and a calibration region. The network entity may send the calibration error information to the UE, to a base station, or to combinations thereof.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a first user equipment (UE) may identify a configuration for multiple path relaying, the multiple path relaying comprising a first path for communications between a wireless node and a remote UE via the first UE and a second path for communications between the wireless node and the remote UE via a second UE. The first UE may determine a first set of resources for the first path and a second set of resources for the second path based at least in part on the configuration for the multiple path relaying. The first UE may receive, from the wireless node, data for the remote UE on the first set of resources, and may transmit the data to the remote UE on the first set of resources.

Abstract: A user equipment (UE) sends an indication supported combinations of sounding reference signal (SRS) resources, unsupported combinations of SRS resources, or compatible SRS resources to a base station. The base station selects one or more SRS resources for the UE from the SRS resources that are supported by the UE or are compatible for the UE. In some examples, the UE receives a configuration from the base station for multiple SRS resource sets. After configuring the UE with multiple SRS resource sets, the base station selects one of the SRS resources sets, and may indicate the selected SRS resource set to the UE. The UE transmits a physical uplink shared channel (PUSCH) to the base station using SRS resources from the selected SRS resource set.
