Abstract
A method for receiving device position determination includes receiving beamformed position reference signals (BF-PRSs) on a plurality of communications beams from at least two transmitting devices in accordance with a BF-PRS configuration, making at least one observed time difference of arrival (OTDOA) measurement in accordance with the BF-PRSs on the plurality of communications beams, and transmitting OTDOA feedback including the at least one OTDOA measurement.
Claims22
A method comprising:
- receiving, by a user equipment (UE), beamformed position reference signals (BF-PRSs) on a plurality of beams from a plurality of network devices in accordance with a BF-PRS configuration;
- measuring, by the UE, a time difference (TD) between a pair of BF-PRSs of the BF-PRSs received from a pair of network devices of the plurality of network devices;
- and
- transmitting, by the UE, a feedback message indicating the TD, the feedback message including identification information identifying the pair of network devices.
A user equipment (UE) comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming, the programming including instructions that, when executed by the at least one processor, cause the UE to perform operations including:
- receiving beamformed position reference signals (BF-PRSs) on a plurality of beams from a plurality of network devices in accordance with a BF-PRS configuration;
- measuring a time difference (TD) between a pair of BF-PRSs of the BF-PRSs received from a pair of network devices of the plurality of network devices;
- and
- transmitting a feedback message indicating the TD, the feedback message including identification information identifying the pair of network devices.
A method comprising:
- transmitting, by a network device to a user equipment (UE), a beamformed position reference signal (BF-PRS), the BF-PRS being one of BF-PRSs on a plurality of beams from a plurality of network devices in accordance with a BF-PRS configuration;
- and
- receiving, by the network device from the UE, a feedback message indicating a time difference (TD) between a pair of BF-PRSs of the BF-PRSs, the pair of BF-PRSs from a pair of network devices of the plurality of network devices, the feedback message including identification information identifying the pair of network devices.
A network device comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming, the programming including instructions that, when executed by the at least one processor, cause the network device to perform operations including:
- transmitting, to a user equipment (UE), a beamformed position reference signal (BF-PRS), the BF-PRS being one of BF-PRSs on a plurality of beams from a plurality of network devices in accordance with a BF-PRS configuration;
- and
- receiving, from the UE, a feedback message indicating a time difference (TD) between a pair of BF-PRSs of the BF-PRSs, the pair of BF-PRSs from a pair of network devices of the plurality of network devices, the feedback message including identification information identifying the pair of network devices.
