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may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.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: A user equipment uses positioning reference signals (PRS) and non-PRS signals for position measurements. The non-PRS signals may be downlink and sidelink signals wherein the non-PRS are downlink or sidelink signals that are transmitted for purposes unrelated to positioning. Positioning assistance data is provided to the UE that associates the non-PRS signals with PRS-IDs. The association of the non-PRS signals to the PRS-IDs may be provided by a location server or serving base station. After performing positioning measurements using non-PRS signals, the UE reports measurement information using the PRS-IDs to identify the non-PRS signals used to generate the positioning measurements.

Abstract: Examples described herein relate to supplementing wireless local area network (WLAN) connection of a wireless having multiple Subscriber Identity Modules (SIMs) in which at least one of the SIMs is associated with a Designated Data Service (DDS) subscription. A method includes connecting the wireless communication device with a wireless local area network (WLAN), receiving a request for transferring data, determining whether a WLAN link rate of the wireless communication device is less than a link rate threshold, transferring the data over the WLAN in response to determining that the WLAN link rate is not less than the link rate threshold, and transferring a first portion of the data over the WLAN and a second portion of the data via the DDS subscription in response to determining that the WLAN link rate is less than the link rate threshold.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a location server, a positioning reference signal (PRS) configuration for a downlink-and-uplink-based positioning session between the UE and the location server, waits, based on a determination that a sounding reference signal (SRS) configuration for the downlink-and-uplink-based positioning session has not been received from a serving base station of the UE, for reception of the SRS configuration from the serving base station until expiration of a timer, and determines, based on the expiration of the timer, whether the SRS configuration was received.

Abstract: A method of managing positioning reference signal transmission includes: instructing a transmission point to apply a muting pattern regarding transmission of a reference signal including first and second reference signal resources, where a first instance of the first reference signal resource includes one or more first resource elements across one or more first OFDM symbols within a slot, and a second instance of the second reference signal resource includes one or more second resource elements across one or more second OFDM symbols within the slot; and instructing the transmission point to transmit, unmuted, at least one of the one or more second resource elements, of at least one of the one or more second OFDM symbols, despite the muting pattern indicating to mute transmission of the at least one of the one or more second resource elements of the at least one of the one or more second OFDM symbols.

Abstract: A mobile device and base station are enabled to support improved positioning accuracy in the presence of phase noise in high frequency radio network, such as in 5G New Radio network operating in mmWave. Phase Tracking Reference Signal (PTRS) may be transmitted with Positioning Reference Signals (PRS) and used for positioning and/or used to correct the phase offset between symbols in the PRS. A request may be made to transmit PTRS alone or with the PRS, or that the PRS is transmitted with a specific PRS frame structure, e.g., with a specific comb value, that minimizes the impact of phase noise. The PTRS or a phase ramp of the staggered symbols in the PRS may be used to estimate and correct the phase offset. Less than all of the symbols transmitted in the PRS may be used to generate positioning measurements to minimize the impact of phase noise.
