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.

Abstract: A system and a method are disclosed for transmission of 5G side link positioning reference signals (SL-PRS) while in 5G side link mode 2 (for example, V2X). Using a shared resource pool and no data transmission, a UE determines three parameters (time, frequency, and PRS index) for transmission of a PRS using a comb structure. Using a dedicated resource pool with data transmission, the UE populates a time frequency grid for slot transmission so that PRS does not conflict with demodulation reference signals (DMRS).

Abstract: A system and a method are disclosed for beam pairing. In some embodiments, the method includes: accessing, by a first User Equipment (UE), configuration data indicating a slot structure including a plurality of resources for transmissions in different directions; and based on the configuration data, transmitting, by the first UE, in a single slot, a first transmission portion using a first resource of the plurality of resources with a first beam direction and a second transmission portion using a second resource of the plurality of resources with a second beam direction, different from the first beam direction.

Abstract: A system and a method are disclosed for positioning. In some embodiments, the method includes transmitting, by a first User Equipment (UE): a first Positioning Reference Signal (PRS) transmission, and, immediately preceding the first PRS transmission, a duplicate of a symbol of the first PRS transmission, the duplicate and the first PRS transmission being in a same slot as: a second PRS transmission, multiplexed in time with the first PRS transmission, transmitted by a second UE, and, immediately preceding the second PRS transmission, a duplicate, of a symbol of the second PRS transmission, transmitted by the second UE.

Abstract: Methods and apparatuses are provided in which a user equipment (UE) determines a resource pool for reception of a sidelink (SL)-positioning reference signal (PRS). The UE receives a slot and determines whether the slot includes resources in the resource pool for the SL-PRS. The UE decodes SL control information (SCI) of the slot using a first format for the SL-PRS, in case that the slot includes the resources in the resource pool.

Abstract: A system and a method are provided in which a user equipment (UE) in a network measures a first carrier phase based on a first reference signal at a first frequency, and a second carrier phase based on a second reference signal at a second frequency that is different from the first frequency. The UE performs a measurement based on the first carrier phase and the second carrier phase. The UE reports the measurement to a location management function (LMF) of the network.

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 method and a device are provide in which a first user equipment (UE) detects first sidelink (SL) control information (SCI) of a second UE. The first UE allocates a first resource in a slot for SL positioning reference signal (PRS) symbols of the first UE, based on the first SCI. A second resource of the slot is for SL-PRS symbols of the second UE. The first resource and the second resource are separated by a first symbol for automatic gain control (AGC) training for subsequent SL-PRS symbols.
