Abstract: A system and a method for positioning by a user equipment (UE) may include receiving, by the UE, a radio resource control (RCC) signal comprising a measurement request, receiving, by the UE, at least two positioning reference signals (PRSs), each of the at least two PRSs corresponding to different fractions of an operating frequency range, determining that the at least PRSs are coherently combinable, aggregating, by the UE, the at least two PRSs in one measurement gap, and reporting, by the UE, measurements based on the aggregating the at least two PRSs.

Abstract: A system and a method are disclosed. The method includes performing, by a first user equipment (UE), a first measurement between a second UE and a third UE, receiving status data from the third UE, the status data including synchronization information associated with the third UE, based on the status data, selecting the third UE for determining the first measurement, and performing a positioning determination based on the first measurement.

Abstract: A method may include generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE), determining a timing error group (TEG) index corresponding to the generated Rx TEG, determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG, and reporting the positioning measurement associated with the Rx TEG index.

Abstract: A system and method for positioning for line-of-sight and non-line-of sight environments. In some embodiments, the method includes: receiving, by a User Equipment (UE), from a first Transmission and Reception Point (TRP) of a network, a Positioning Reference Signal (PRS); and sending, by the UE, a response to the network. The sending may include sending an indicator, the indicator indicating whether the UE has performed a measurement based on the Positioning Reference Signal, received via a line-of-sight path; or the sending may include identifying a first detected path and sending a plurality of measurements to the network, the plurality of measurements including, for each of a first plurality of paths, the arrival time difference relative to the arrival time of the first detected path, the first plurality of paths not including the first detected path, and the first plurality of paths including two paths.

Abstract: A system and method for positioning in RRC Idle and Inactive states. In some embodiments, the method includes receiving, by a user equipment (UE), in Idle or Inactive state, a downlink positioning reference signal (PRS); transmitting, by the UE, in Idle or Inactive state, an uplink reference signal; and transmitting, by the UE, in Idle or Inactive state, a PUSCH carrying an estimate of the position of the UE. The uplink reference signal may be a positioning sounding reference signal (SRS), or a Physical Random Access Channel (PRACH) preamble with sequence length greater than 1151.
