Abstract: Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.

Abstract: Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a receiver device receives, from a transmission point, a reference RF signal on a wireless channel receives, from a positioning entity, an indication that the reference RF signal serves as a source for a quasi-collocation (QCL) type(s) for positioning reference RF signals received by the receiver device from the transmission point on the wireless channel, measures an average delay, a delay spread, or both the average delay and the delay spread of the reference RF signal based on the QCL type(s), receives, from the transmission point, a positioning reference RF signal on the wireless channel, and identifies a time of arrival (ToA) of the positioning reference RF signal based on the measured average delay, the delay spread, or both the average delay and the delay spread of the reference RF signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report measurements of a signal transmitted by a base station via a waveform. Based on the waveform, the base station may determine a position of the UE. The UE may measure the signal in a frequency band, where additional signaling in an adjacent frequency band causes interference on the signal. The UE may determine characteristics for measuring the signal based on the interference and may generate samples of the signal based on the measurement characteristics. Additionally, the UE may identify one or more antennas for measuring the signal and generate the samples based on the identified antennas. The UE may transmit the waveform report to the base station based on the samples. In some cases, the waveform may be based on a fractional symbol reporting scheme or a time mask with an offset and sampling rate.

Abstract: A reference signal may provide for enhanced bandwidth utilization to enable highly accurate position determination with relatively low bandwidth. For a given allocated bandwidth, a reference signal may use of only a portion of the allocated bandwidth by using plurality of sub-bands. In some cases, the sub-bands may be near the edges of the allocated band to maximize Gabor bandwidth.

Abstract: Many mobile devices and mobile networks utilize orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, the Doppler Effect and other noise or obstructions can cause OFDM signals to become entangled, particularly when the mobile device is moving, making the calculated position information inaccurate. Described herein are systems and methods for disentangling the OFDM signals by calculating a symbol length for the signals that is longer than the minimum symbol length, which is used in traditional OFDM. Selecting a longer symbol length reduces the Doppler Effect and other noise on the signals, making positioning calculations more accurate.

Abstract: A mobile station performs Observed Time Difference of Arrival (OTDOA) positioning by measuring a time of arrival (TOA) of downlink signals transmitted from a reference cell and one or more neighbor cells. Reference Signal Time Differences (RSTDs) are generated using TOA measurements from the reference cell and each neighbor cell. The mobile station reports to a location server location information, including the RSTD measurements and the times of measurement for the TOA measurements. The mobile station may further generate and report additional RSTD and/or TOA measurements and associated times of measurement for the reference cell and/or neighbor cells. A location server may use the RSTD measurements, the times of measurement and any TOA measurements to determine a position of the mobile station taking into account user motion and base station clock drift and/or may adjust the uncertainty of the resulting position.

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: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: Disclosed are techniques for determining round-trip time (RTT) of a user equipment (UE). In an aspect, each gNodeB in a plurality of gNodeBs measure signaling data related to an uplink RTT reference signal received from the UE and the downlink RTT reference signal transmitted by each gNodeB. The signaling data comprises one of a processing delay between a time of arrival (TOA) of the uplink RTT reference signal and a time of transmission (TOT) of the downlink RTT reference signal or a total RTT between the TOT of the downlink RTT reference signal and the TOA of the uplink RTT reference signal. The signaling data is sent to a single entity, other than the UE, e.g., another gNodeB or a location server, where signaling data relevant to the UE is aggregated. The aggregated signaling data may be sent to the UE to determine the RTT for the UE or used by the location server to determine the RTT for the UE.
