Abstract
An apparatus receives a plurality of sound wave signals for a plurality of channels by respectively using a plurality of sound wave receivers; selects a reference sound wave receiver for each of the plurality of channels from among the plurality of sound wave receivers; and calculates a reception time difference between two channels on the basis of a sound wave signal reception time of the reference sound wave receiver for each channel and measures the location of the apparatus on the basis of the reception time difference.
Claims13
A method by a user equipment (UE) comprising:
- receiving a plurality of acoustic signals for a plurality of channels by using each of a plurality of acoustic receivers;
- selecting a reference acoustic receiver for each of the plurality of channels among the plurality of acoustic receivers;
- and
- calculating a reception time difference between two channels based on a reception time of an acoustic signal at the reference acoustic receiver for each channel, and measuring a position of the UE based on the reception time difference,
- wherein the reference acoustic receiver is independently selected for each channel through comparison of reception quality of acoustic signals at the plurality of acoustic receivers for each of the plurality of channels.
(canceled)
A user equipment (UE) comprising:
- a plurality of acoustic receivers;
- and
- a processor connected to the plurality of acoustic receivers,
- wherein the processor is configured to:
- receive a plurality of acoustic signals for a plurality of channels by using each of the plurality of acoustic receivers;
- select a reference acoustic receiver for each of the plurality of channels among the plurality of acoustic receivers;
- and
- calculate a reception time difference between two channels based on a reception time of an acoustic signal at the reference acoustic receiver for each channel, and measure a position of the UE based on the reception time difference,
- wherein the reference acoustic receiver is independently selected for each channel through comparison of reception quality of acoustic signals at the plurality of acoustic receivers for each of the plurality of channels.
(canceled)
A method by a network comprising:
- transmitting acoustic signals to a user equipment (UE) on a plurality of channels through a plurality of anchors;
- receiving, from the UE, measurement information comprising information on a reception time difference between two channels among the plurality of channels;
- and
- measuring the position of the UE based on the measurement information,
- wherein the measurement information further comprises mapping information for a reference acoustic receiver independently selected for each channel among the plurality of acoustic receivers.
