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: In one example, a method comprises: receiving assistance data from a location server; classifying a plurality of candidate cells in the assistance data into a first group of candidate cells and a second group of candidate cells, wherein the classification is based on whether a candidate cell transmits position reference signal (PRS) symbols in one or more multimedia broadcast single frequency network (MBSFN) subframes in a positioning occasion, and based on a cyclic prefix (CP) length of the PRS symbols being transmitted by the candidate cell in the positioning occasion; selecting, based on one or more predetermined criteria, one of the first group or the second group of candidate cells to measure the one or more PRS in the positioning occasion; and measuring the one or more PRS from one of the first group or the second group of candidate cells in the positioning occasion to measure PRS measurements.

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.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for saving power while performing radio access technology measurements. An exemplary method that may be performed by user equipment (UE) includes obtaining a configuration indicating a measurement gap for the UE to measure one or more non-serving cells, wherein the UE does not receive data transmissions from a serving cell during the measurement gap, deciding not to measure the non-serving cells during a period including at least a portion of the measurement gap, and deactivating a receive chain of the UE during the period.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a cycle length of an extended discontinuous reception (eDRX) cycle, and may determine whether the UE is in a condition, associated with triggering a tracking area update, during an on duration of the eDRX cycle. The UE may selectively increase or decrease the cycle length of the eDRX cycle based at least in part on determining whether the UE is in the condition. The cycle length may be decreased when the UE is in the condition or may be increased when the UE is not in the condition. Numerous other aspects are provided.

Abstract: A method of measuring a wireless OFDM PRS at a user equipment includes: selecting a symbol subset of a symbol group of the OFDM PRS, the OFDM PRS comprising a slot of symbols comprising the symbol group, the symbol group consisting of a first symbol quantity of consecutive ones of the symbols, the symbol group being fully staggered in frequency domain, the symbol subset consisting of a second symbol quantity of the symbols of the symbol group, the second symbol quantity being smaller than the first symbol quantity, and the symbol subset being less than fully staggered in the frequency domain; and measuring the symbol subset without measuring all of the symbols of the symbol group.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) transmits, to a serving base station, in one or more active bandwidth parts (BWPs) of the UE, a request for a no-downlink-scheduling gap, the request including at least time-domain parameters related to scheduling the no-downlink-scheduling gap, receives, from a neighboring base station, in the one or more active BWPs, a downlink positioning reference signal (DL-PRS) during the no-downlink-scheduling gap, and transmits, in the one or more active BWPs, an uplink positioning reference signal (UL-PRS) during the no-downlink-scheduling gap in response to reception of the DL-PRS.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques allow a user equipment (UE) to efficiently identify a trigger state that is linked to a configuration for receiving and measuring reference signals from a transmission and reception point (TRPs). The UE may receive an indication of different lists of trigger states associated with different TRPs, and, when the UE receives downlink control information (DCI) indicating a trigger state index, the UE may reference an appropriate list to identify the trigger state corresponding to the trigger state index. In particular, the UE may determine a control resource set (CORESET) pool index of a CORESET in which the DCI is received, and the UE may identify the trigger state corresponding to the trigger state index from a list of trigger states associated with the CORESET pool index.

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.
