Embodiments of the present disclosure provide a communication method and apparatus, a device, a system and a storage medium, which relate to the field of communication technology, and can enable a first device, which cannot communicate with a second device through a beam due to obstacle blocking, to acquire a second position and wireless signal information corresponding to the second position through indication information so that the first device can move to the second position and communicate with the second device at the second position, improving the capability of the first device to maintain high-speed data transmission with the second device, enabling the first device to quickly move from a position with poor signal coverage to a nearby position with better signal coverage, and thus achieving wireless signal transmission with a higher data rate, lower latency, and higher reliability.

An apparatus for localizing a target user equipment (“UE”) sidelink (“SL”) positioning includes a processor configured to cause the target UE to receive from a sidelink configuration source SL positioning reference signals (“SL PRS”) assistance data associated with SL reference signal transmissions e.g., beam transmissions, transmitted from one or more SL signal transmitting devices. The target UE receives transmitted SL signal information from the one or more SL signal transmitting devices and performs SL signal angle of arrival (“AoA”) measurements or SL reference signal received power (“SL RSRP”) measurements for deriving angle of departure (“AoD”) mapped to the received SL RSRP measurements or performs SL radio resource management measurements (“SL-RMM”) for determining an estimated location of the target UE using SL-AoD, SL-AoA, SL-RMM positioning techniques or combinations thereof.

Disclosed are techniques for group reporting of UE receive-transmit (Rx-Tx) time difference measurements for multi-RTT positioning. A plurality of downlink reference signals (DL RSs) are received from a plurality of transmission reception points (TRPs). A corresponding plurality of uplink reference signals (UL RSs) are transmitted to the plurality of TRPs. One or more numerology factors are determined for the plurality of TRPs. A measurement report is generated for the plurality of TRPs based on the numerology factors. The measurement report is transmitted to a network entity. The measurement report includes UE receive-transmit (Rx-Tx) time difference measurements for at least two of the TRPs.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network entity, a request to provide an enhanced positioning measurement report comprising a positioning measurement and further comprising a report of components of a channel power delay profile (PDP), a report of a probability distribution of times of arrival (ToA), or both. The UE may determine an enhanced measurement period required by the UE to perform the enhanced positioning measurement, wherein the enhanced measurement period is longer than a standard measurement period required by the UE to perform a non-enhanced positioning measurement. The UE may perform the enhanced positioning measurement using the enhanced measurement period. The UE may provide the enhanced positioning measurement report to the network entity.

Various embodiments provide systems and method for monitoring individuals.

One instance of a user equipment (UE) apparatus includes a target UE configured to receive sidelink (“SL”) positioning reference signals (“SL-PRS”) from a reference node and two or more additional UEs, measure SL reference signal timing differences (“RSTDs”) between the two or more additional UEs with respect to the reference node, and determine an estimated location of the target UE based on a time-difference-of-arrival (“TDOA”) positioning technique using the SL RSTDs. Another instance of UE apparatus includes a target UE configured to transmit SL-PRS to one or more additional UEs, receive SL positioning reference signals from a one or more additional UEs, and determine an estimated location of the target UE based on a SL round-trip time (“RTT”) positioning technique using the SL-PRS transmitted and received between the target UE and additional UEs.

Disclosed are techniques for reducing the overhead of low layer positioning reports. In an aspect, a user equipment (UE) performs at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from at least one transmission-reception point (TRP) during a positioning session, and reports, to a positioning entity via low layer signaling, a relative value of the at least one positioning measurement relative to an expected value of the at least one positioning measurement, wherein the relative value of the at least one positioning measurement is a difference between the expected value of the at least one positioning measurement and a measured value of the at least one positioning measurement.

A user equipment (UE) configured for position determination receives positioning assistance data from a location server that is positioning method specific and provides information related to the prioritization of one or more of frequency layers, transmission points (TRPs), Positioning Reference Signal (PRS) resource sets, and PRS resources or a combination thereof. The positioning assistance data may be generated by the location server in response to the UE measurement capabilities. The UE determines a prioritization for PRS measurements based at least on one or more orderings of the information for the frequency layers, the TRPs, the PRS resource sets, or the PRS resources in the positioning assistance data, or a combination thereof and the positioning method. Downlink PRS are measured by the UE based on the prioritization.

In an aspect, a UE receives first positioning assistance data (AD). The UE transmits an indication to a network component (e.g., BS, core network component, LMF, etc.) that the UE has received the first positioning AD. The network component determines second positioning AD that is based at least in part upon the first positioning AD. The network component transmits the second positioning AD to the UE.

A method of using reference signals from different radio access technologies (RATs) for user equipment (UE) positioning includes, by the UE, receiving assistance data indicating an association between first reference signals of a first RAT and second reference signals of a second RAT in a frequency band, determining that the first reference signals and the second reference signals are deployed in the frequency band based on the assistance data, receiving the first reference signals and the second reference signals in the frequency band from one or more network nodes, determining the association between the first reference signals and the second reference signals based on configuration data, and determining positioning data associated with the location of the UE based on the determined association and both the received first reference signals and the received second reference signals.
