Abstract: Disclosed are techniques for positioning. A receiver receives complementary timing information associated with the positioning reference signals (PRS) of a repetition of a PRS sequence. The complementary timing information distinguishes a repetition of a PRS sequence from remaining repetitions of the PRS sequence. Based on the complementary timing information associated with different PRS from different non-terrestrial vehicles indicating that the PRS were transmitted during the same radio frame, the receiver can determine an observed time difference of arrival (OTDOA) between the PRS received from the respective non-terrestrial vehicles.

Abstract: A low complexity user equipment (UE) may be in communication with another UE (e.g., with a premium UE or more capable UE) via a device-to-device communication link (e.g., via sidelink), and the low complexity UE may leverage the device-to-device link to improve (e.g., simplify, expedite, etc.) random access procedures performed by the low complexity UE. For example, a low complexity UE may request contention free random access (CFRA) resources via the device-to-device link with another UE. Another device (e.g., another UE in device-to-device communication with the low complexity UE) may receive the request from the low complexity UE and forward the request to the network (e.g., to a base station). The network may then configure CFRA resources for the low complexity UE. Upon receiving the CFRA configuration, the low complexity UE may perform a random access procedure (e.g., a CFRA procedure) with the network (e.g., with the base station) accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may transmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration for UE paging is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a paging communication. Numerous other aspects are provided.

Abstract: A configuration for a UE that measures CLI to determine the reception timing of the CLI signal transmitted from a UE in another cell. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of measuring CLI signals by improving the manner in which a wireless device determines the reception timing of a transmitted CLI signal. An apparatus receives a first downlink signal from a first base station. The apparatus receiving a second downlink signal from a second base station. The apparatus determines a CLI signal measurement from a second UE received at the first UE based on a propagation delay difference, the propagation delay difference being based on the first downlink signal and the second downlink signal.

Abstract: A user equipment (UE) may be configured to generate a preamble of a first message associated with a random access channel (RACH) procedure, such as a two-step RACH procedure. The UE may be further configured to determine an identifier (ID) associated with the UE based on at least one of an ID associated with the preamble or a port index associated with a demodulation reference signal (DMRS). The UE may generate a payload of the first message that indicates the ID associated with the UE. The UE may then transmit the first message to a base station to initiate the RACH procedure. Potentially, the UE may receive a second message from the base station responsive to the first message, and the second message may confirm the ID associated with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for a first cell, wherein the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. A first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.
