Abstract: A radar system may comprise a first wireless communications system Transmission Reception Point (TRP)configured as a transmitter for sending a transmit signal toward a target, a second wireless communications system TRP configured as a receiver for receiving an echo signal corresponding to a reflection of the transmit signal from the target, and a radar server. The first wireless communications system TRP and the second wireless communications system TRP may be part of a cellular communications system. The second wireless communications system TRP may be configured to generate one or more measurement reports containing one or more of delay, Doppler frequency, and/or angle-of-arrival information. The second wireless communications system TRP may be configured to send the one or more measurement reports to an entity within the cellular communications system.

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: 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.
