Abstract: Techniques are disclosed for enabling low-power positioning of a first mobile device using differential angle of arrival (AoA). A differential AoA between a first AoA of a first wireless reference signal at a second mobile device and a second AoA of a second wireless reference signal at the second mobile device is obtained, where the first wireless reference signal is transmitted by a wireless network node, and the second wireless reference signal is transmitted by the first mobile device. The position of the first mobile device is determined based at least in part on the differential AoA. The position of the first mobile device is then provided.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may receive positioning assistance data for a plurality of cells, the positioning assistance data including at least a first positioning reference signal (PRS) configuration for a first cell of the plurality of cells and a second PRS configuration for a second cell of the plurality of cells. The UE may perform a handover from the first cell to the second cell during a positioning session with at least the first cell and the second cell. The UE may, after the handover, measure PRS from the second cell based on the second PRS configuration.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiving entity (RE), e.g., a user equipment or base station, receives a positioning resource beam configuration that defines a set of positioning resources, each positioning resource being transmitted by a transmission/reception point (TRP) at different times using different beams, each of the different beams having a set of beam characteristics that differs from the set of beam characteristics of another of the different beams in at least one beam characteristic. The RE performs positioning measurements on the different beams at the different times, at least based on the sets of beam characteristics, and sends positioning information to the TRP, the positioning information comprising at least some of the positioning measurements, a positioning estimate, or combinations thereof.

Abstract: Reference signals used in location estimation of a user equipment (UE) in a wireless data network can be secured against a man-in-the-middle attack by a transmitting device withholding the conveyance of transmission parameters for decoding portions of a reference signal until after the portions are transmitted. Thus, receiving devices can buffer received signals and, after receiving the transmission parameters, process the buffered signals. To further prevent an attacker device from attacking future reference signals, transmission parameters can be nondeterministic such that an attacker device obtaining a parameter at a certain period of time is unable to use the decoded parameter predict or determine subsequent transmission parameters.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiving entity receives information that characterizes a set of positioning signals to be transmitted by a transmission/reception point (TRP) using a set of transmission beams, the information comprising at least one antenna element radiation pattern, at least one antenna element array configuration, and, for each beam in the set of transmission beams, information identifying at least one precoding matrix. The receiving entity performs measurements of the positioning signals transmitted by the TRP, and calculates at least one positioning measurement estimate based on at least some of the at least one antenna element radiation pattern, the at least one antenna element array configuration, the information identifying at least one precoding matrix, and the positioning measurements. The receiving entity sends positioning information to the TRP. The positioning information may include the at least one positioning measurement estimate.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) derives a time reversal (TR) precoder based at least in part on an estimated channel between the first UE and a second UE, and sends, to the second UE, a TR-precoded sidelink (SL) positioning reference signal (PRS). The estimated channel may be based on channel state information (CSI) associated with a wideband (WB) reference signal (RS). The TR precoder may be based on transmissions or receptions on a SL communication channel between the first UE and the second UE.

Abstract: Techniques are provided for utilizing a sidelink discovery interface to determine a location of a user equipment (UE). An example method for determining a location of a mobile device according to the disclosure includes receiving one or more reference signals transmitted via a first radio access technology, determining measurement values for the one or more reference signals, receiving a discovery signal from a station via a second radio access technology that is different from the first radio access technology, wherein the discovery signal includes and identification value associated with the station, and obtaining the location based at least in part on the measurement values and the discovery signal.

Abstract: In an embodiment, a serving BS of a UE may transmit a PDCCH communication to the UE. The PDCCH communication triggers a partial RACH procedure, whereby a RACH transmission is performed. In some designs, the RACH transmission is for positioning, and positioning measurements are performed at the serving BS and (optionally) at one or more non-serving BSs. In some designs, measurement data based on the positioning measurements are conveyed to a position estimation entity (e.g., LMF), which performs a positioning estimate of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit control signaling scheduling a downlink transmission to a user equipment (UE) across multiple bandwidth parts (BWPs) and an indication of a code block group (CBG)-based mapping for the downlink transmission. A transport block (TB) of the downlink transmission may include multiple code block groups (CBGs) that are mapped across the BWPs. The UE may monitor for the TB across the BWPs based on the CBG mapping. For example, the UE may determine the CBGs are mapped across different BWPs based on the cross-BWP CBG mapping. Additionally or alternatively, the UE may determine each CBG is mapped within one BWP based on the cross-BWP CBG BWPs mapping. The UE may calculate a TB size based on available time and frequency resources and may decode the TB based on calculating the TB size and the cross-BWP CBG mapping.
