摘要： 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.

摘要： Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives positioning reference signal (PRS) resources of a PRS instance, receives at least one symbol of a high priority downlink channel scheduled during a PRS processing window for the PRS instance, wherein the high priority downlink channel is determined to have high priority based on the high priority downlink channel being associated with a high priority uplink channel, and refrains from processing the PRS resources of the PRS instance during the PRS processing window based on one or more conditions related to prioritizing PRS processing, wherein the one or more conditions indicate that the UE does not expect to process the PRS resources of the PRS instance during the PRS processing window based on the at least one symbol of the high priority downlink channel being scheduled during the PRS processing window.

摘要： A method of wireless communication at a UE is disclosed herein. The UE obtains, via an antenna of the UE, a first indication of a first measurement of at least one RF signal at a first time instance. The UE obtains, via the antenna, a second indication of a second measurement of the at least one RF signal at a second time instance. The UE calculates a distance traveled by the UE between the first time instance and the second time instance. The UE calculates a DOA of the at least one RF signal based on the first measurement, the second measurement, and the distance traveled by the UE between the first time instance and the second time instance. The UE outputs a third indication of the calculated DoA of the at least one RF signal.

摘要： Antenna hopping techniques for Positioning Reference Signal (PRS) measurements in positioning of a user equipment (UE) include, for each of a plurality of successive measurement instances, taking a set of measurements of a respective set of PRS resources during the respective measurement instance using only one subset of a plurality of subsets of antennas of the UE, such that different subsets of the plurality of subsets of antennas of the UE are used for different measurement instances of the plurality of successive measurement instances. Each subset comprises one or more, but fewer than all, antennas of the UE. Techniques include sending one or more measurement reports from the UE to a location server. Each of the one or more measurement reports may comprise: information indicative of a respective set of measurements, and a timestamp corresponding to the respective measurement instance during which the respective set of measurements were taken.

摘要： In an aspect, a wireless node (e.g., UE, gNB, etc.) receives a reference signal for positioning (RS-P) over a respective bandwidth on one or more paths including an earliest path, and measures a reference signal received power (RSRP) associated with the earliest path of the RS-P based on a sum of energy on the respective bandwidth within at least one number of samples from a peak of the earliest path.

摘要： A method of reporting measurements of an uplink positioning reference signal includes: receiving, at a base station, the uplink positioning reference signal from a user equipment; determining, at the base station, a plurality of measurement values of the uplink positioning reference signal, each of the plurality of measurement values being of a same type of measurement, and corresponding to the uplink positioning reference signal; and sending, from the base station to a server, a report including the plurality of measurement values of the uplink positioning reference signal and at least one indication that the plurality of measurement values corresponds to a same uplink positioning reference signal.

摘要： Methods, systems, and devices for transmit power control for positioning using non-serving cells are described. A user equipment (UE) may determine that an uplink reference signal may be associated with a positioning procedure. In some cases, the positioning procedure may include transmission, by the UE, of the reference signal to a non-serving cell, which may be farther away from the UE than a serving cell. The UE may determine an absence of a parameter associated with a transmit power for transmitting the reference signal. Based on the absence, the UE may determine the transmit power based on parameters received from a serving cell, based on configuration information, based on a message intercepted from the cell other than the serving cell, or based on other considerations or information.

摘要： A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

摘要： A method of user equipment (UE) positioning includes receiving positioning assistance data associated with a Transmission Reception Point (TRP), such as an expected Reference Signal Time difference (RSTD) between a reference cell and the TRP. The method also includes capturing, based on at least the expected RSTD, a first portion of reference signals from the TRP, where, at the UE, the first portion of the reference signals does not overlap in time with non-reference signals from the reference cell. The method further includes determining a first Time of Arrival (TOA) of the reference signals from the TRP based on the first portion of the reference signals.
