Abstract: In an aspect, a serving BS of a UE measures ToAs of a DL-PRS from a non-serving base station of the UE and an UL-SRS-P from the UE. The serving BS transmits measurement information based on the ToA measurements of the DL-PRS and the UL-SRS-P to a position estimation entity. The position estimation entity determines a positioning estimate for the UE based in part upon the measurement information.

Abstract: In an aspect, a radar controller determines a radar slot format that configures transmission of a reference radar signal on a first symbol over a first link from a first base station to a second base station followed by at least one target radar signal on at least one second symbol over at least one second link from the first base station to the second base station, and transmits an indication of the radar slot format to the first base station and the second base station. The first base station transmits, and the second base station receives, the reference radar signal and the at least one target radar signal in accordance with the radar slot format.

Abstract: Techniques and devices for wireless communications are described. A user equipment (UE) may receive a configuration from a network entity for multiplexing a reference signal with a data signal in time and in frequency or for multiplexing the reference signal in a Doppler domain. The UE may receive an assignment of multiple time-frequency resources from the network entity for transmission of the reference signal. The UE may multiplex the reference signal across the assigned time-frequency resources in accordance with the received configuration. The UE may transmit the multiplexed reference signal to the network entity.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may identify at least one communication resource from a plurality of communication resources for transmitting a positioning report, wherein the plurality of communication resources for transmitting the positioning report have different priorities. The UE may transmit the positioning report via the at least one communication resource, wherein the at least one communication resource comprises at least one of a medium access control (MAC) control element (MAC-CE) logical channel ID or a signaling radio bearer (SRB).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate a connection release message via a first beam to release a connection between the UE and a network entity. The UE may obtain an indication associated with a second beam of a non-terrestrial network entity indicating a set of one or more beams associated with a paging early indication. The UE may monitor for the PEI paging message based on whether the first beam is included in the set of one or more beams. Alternatively, the UE may skip monitoring for the PEI based on the first beam being excluded from the set of one or more beams, and the UE may monitor for a paging message during a paging occasion. In some examples, the UE may receive a message indicating the set of one or more beams from the non-terrestrial network entity.

Abstract: Techniques are provided for calibrating group delay for a low-tier UE by leveraging the relatively high accuracy of RTT positioning for a premium UE. This can enable online/in-field group delay calibration of low-tier UEs, allowing for low-tier UEs to be calibrated when needed. Depending on desired functionality, techniques for calibration may include the use of RTT measurements with a base station, or an RTT measurement between the low-tier UE and the premium UE.

Abstract: Radio frequency (RF) sensing of a target object by a wireless network is supported by a sensing node and a network node using sensing assistance data. The sensing assistance data may include information for Doppler estimation from received RF signals. The information for Doppler estimation, for example, may include an indication of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer or any combination thereof. The sensing assistance data may include an association of PRS resources and reference point objects (RPOs) so RF signals reflected from the RPOs may be excluded from the sensing measurements. The sensing assistance data may include beam pattern information for PRS resources for beam coordination for RF sensing.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a time period during which the UE is configured to receive grants scheduling communications for the UE, wherein the grants are associated with a first grant format type. The UE may determine that the grants include a feedback process identifier exceeding a threshold value. The UE may maintain a power saving state of a discontinuous reception procedure for a feedback process associated with the feedback process identifier during the time period based at least in part on the feedback process identifier exceeding the threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a waveform threshold for selecting a waveform type for transmitting a message of a random access procedure. The UE may select the waveform type for the message of the random access procedure based on the waveform threshold and a value associated with a power of signals received at the UE. The UE may transmit the message of the random access procedure to a network entity according to the waveform type selected for the message.
