Abstract: A method of sending measurement information from a user equipment includes: measuring a reference signal; producing a measurement report payload based on measurement of the reference signal; encoding the measurement report payload in accordance with ASN.1 (Abstract Syntax Notation One) encoding, and in accordance with a lower-layer protocol to produce an encoded payload, the lower-layer protocol being either a physical-layer protocol or a MAC-layer (Medium Access Control layer) protocol; and sending a lower-layer message based on the encoded payload from the user equipment to a network entity.

Abstract: 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may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration indicating one or more PRS resources transmitted on one or more antenna ports of at least one antenna panel of a base station, measures the one or more PRS resources over a set of angles, wherein the UE is configured to search for the one or more PRS resources over the set of angles based on the PRS configuration, and determines an angle of the set of angles over which at least one PRS resource of the one or more PRS resources was measured as a downlink angle-of-departure (DL-AoD) between the base station and the UE.

Abstract: 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.

Abstract: Disclosed are various techniques for wireless communication. In some aspects, a method of wireless communication performed by a user equipment (UE) includes determining a positioning reference signal (PRS) to random access channel (RACH) occasion (RO) mapping that defines specific ROs during which the UE should at least transmit a RACH sequence based on specific PRS measurements. The method also includes performing at least one PRS measurement. The method also includes transmitting a RACH sequence on at least one RO according to the PRS to RO mapping and based on the specific PRS measurement. The method optionally includes reporting a result of the PRS measurement to the base station according to the PRS to RO mapping based on the PRS measurements.

Abstract: A user equipment (UE) receives scheduling information for Sounding Reference Signal (SRS) for positioning that includes multiple reserved occasions to transmit the SRS. The multiple reserved occasions may be used on all or on only a subset of configured SRS resources. The UE transmits the positioning SRS on a reserved occasion that is first available for transmission, e.g., without collision or other restrictions of transmission of the SRS. The UE does not transmit the positioning SRS on any earlier reserved occasions that is not available or any subsequent reserved occasions. The base station may attempt to decode the SRS on each reserved occasion until the positioning SRS is transmitted. The base station may reassign unused reserved occasions to other UEs or to other channels. The base station may report positioning measurements with associated time stamps for the reserved occasion on which the positioning SRS was received.
