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.
Claims28
A method for device position determination, the method comprising:
- receiving, by a device, beamformed position reference signals (BF-PRSs) on a plurality of beams from transmitting devices in accordance with a BF-PRS configuration;
- measuring, by the device, a first time difference (TD) between two BF-PRSs of the BF-PRSs received from two of the transmitting devices;
- measuring, by the device, a second TD between a different two BF-PRSs;
- and
- transmitting, by the device, a feedback message identifying the two BF-PRSs used for the measuring the first TD, wherein the feedback message further identifies the different two BF-PRSs.
A device comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- receive beamformed position reference signals (BF-PRSs) on a plurality of beams from transmitting devices in accordance with a BF-PRS configuration;
- measure a first time difference (TD) between two BF-PRSs of the BF-PRSs received from at least two of the transmitting devices;
- measure a second TD between a different two BF-PRSs;
- and
- transmit a feedback message identifying the two BF-PRSs used for measuring the first TD, wherein the feedback message further identifies the different two BF-PRSs.
A method for device position determination, the method comprising:
- transmitting, by a first transmitting device, a beamformed position reference signal (BF-PRS) configuration to a device;
- transmitting, by the first transmitting device, a first BF-PRS on at least a first beam in a plurality of beams to the device in accordance with a BF-PRS configuration;
- and
- receiving, by the first transmitting device, a feedback message identifying the first BF-PRS and a second BF-PRS transmitted from a second transmitting device to the device over a second beam in the plurality of beams in accordance with the BF-PRS configuration.
A first transmitting device comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- transmit a beamformed position reference signal (BF-PRS) configuration to a device;
- transmit a first BF-PRS on at least a first beam in a plurality of beams to the device in accordance with a BF-PRS configuration;
- and
- receive, from the device, a feedback message identifying the first BF-PRS and a second BF-PRS transmitted from a second transmitting device to the device over a second beam in the plurality of beams in accordance with the BF-PRS configuration.
