Abstract: Disclosed are techniques for handling of radio frequency front-end group delays (GDs) for round trip time (RTT) estimation. In an aspect, a network entity determines information indicating a network total GD and a user equipment (UE) determines information indicating a UE total GD. The network entity transmits one or more RTT measurement (RTTM) signals to the UE, each including a RTTM waveform. The UE determines one or more one or more RTT response (RTTR) payloads for one or more RTTR signals, each including a RTTR waveform. The UE transmits the RTTR signal(s) to the network entity. For each RTTR signal, a transmission time of the RTTR waveform and/or the RTTR payload is/are determined based on the UE total GD. The network entity determines a RTT between the UE and the network entity based on the RTTM signal(s), the RTTR signal(s), and the information indicating the network total GD.

Abstract: 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.

Abstract: A method of performing positioning operations at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode and OFF times of the discontinuous reception mode; and determining, at the user equipment, whether to measure a portion of a positioning signal based on timing of the portion of the positioning signal relative to at least one of a first one of the ON times of the discontinuous reception mode or a first one of the OFF times of the discontinuous reception mode.

Abstract: Techniques are provide for passive positioning of user equipment (UE) with analog beamforming. An example method for positioning a user equipment includes receiving a first positioning reference signal from a first base station at a first time, receiving a first timing difference value based on two or more positioning reference signals transmitted from the first base station, receiving a second positioning reference signal from a second base station at a second time, receiving a second timing difference value based on two or more positioning reference signals transmitted from the second base station, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the first timing difference value and the second timing difference value.

Abstract: A method comprises: selecting, from a first number of first receive (RX) beams having a first beam width, a first RX beam to form a first beam-pair with a first transmit (TX) beam from one or more base stations, the selection being based on a first measurement of a first reference signal received by the UE using the first beam-pair; selecting, from a second number of second RX beams having a second beam width, a second RX beam to form a second beam-pair with the first TX beam, the selection being based on a second measurement of a second reference signal received by the UE using the second beam-pair, the second number of second RX beams being smaller than the first number of first RX beams, the second beam width being narrower than the first beam width; and performing a location estimate operation using either the second beam-pair, or a third beam-pair derived from the second beam-pair.

Abstract: In an embodiment, a serving BS of a UE may transmit a PDCCH communication to the UE. The PDCCH communication triggers a partial RACH procedure, whereby a RACH transmission is performed. In some designs, the RACH transmission is for positioning, and positioning measurements are performed at the serving BS and (optionally) at one or more non-serving BSs. In some designs, measurement data based on the positioning measurements are conveyed to a position estimation entity (e.g., LMF), which performs a positioning estimate of the UE.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from a network entity, a configuration of one or more positioning reference signal (PRS) resources to measure during a positioning session, the one or more PRS resources having a PRS periodicity TPRS and a PRS occasion length LPRS, and measures the one or more PRS resources during a measurement period, wherein the measurement period is based on a number of measurement instances of the one or more PRS resources the UE is expected to process multiplied by a periodicity parameter, wherein the periodicity parameter is based on a PRS processing window of ‘T’ milliseconds, the PRS periodicity TPRS, and a measurement gap periodicity of at least one measurement gap.

Abstract: In a positioning session for a user equipment (UE), one or more base stations may receive and derive positioning measurements from uplink (UL) transmission from the UE that include a physical resource block (PRB) interlaced waveform based on at least one of interlaced physical uplink control channel (PUCCH) resource blocks, interlaced physical uplink shared channel (PUSCH) RBs resource blocks, interlaced sounding reference signal (SRS), interlaced uplink (UL) positioning reference signal (PRS), or a combination thereof. The interlaced waveforms span a greater wavelength than if interlacing were not used, and an enhanced accuracy requirement for the positioning measurements based on the span may be used for the positioning measurements. The UL interlaced PRBs may be used for UL positioning measurements for combined downlink (DL) and UL positioning measurements. The base station may report the positioning measurements along with the channel used and enhanced accuracy requirements to a location server for positioning.

Abstract: Disclosed are techniques for transmitting and processing reference signals for positioning estimation over a multipath multiple-input multiple-output (MIMO) channel. In aspects, a first node configures first and second reference signal resource sets for transmission of first and second sets of reference signals, wherein the first and second reference signal resource sets occur on first and second subbands of, and/or during first and second time intervals on, the MIMO channel, wherein each reference signal resource in the first and second reference signal resource sets utilize at least first and second MIMO precoders, and transmits, to a second node over the MIMO channel, the first and second sets of reference signals, wherein the first node transmits the first and second sets of reference signals to assist the second node to perform a positioning measurement based on joint processing of the first and second sets of reference signals.
