Abstract
Aspects of the present disclosure provide techniques for efficient ranging. According to certain aspects, techniques are provided to signal the use of different resolutions of time units for parameters to be used in a ranging procedure, such as a fine timing measurement (FTM) procedure.
Claims30
An apparatus for wireless communications, comprising:
- a processing system configured to generate a first frame having at least one bit indicating one or more resolutions of units of time of a plurality of resolutions of units of time to use for one or more parameter fields to be used in a ranging procedure performed with a wireless node;
- and
- a first interface configured to output the first frame for transmission to the wireless node.
An apparatus for wireless communications, comprising:
- a first interface configured to obtain a first frame transmitted from a wireless node;
- and
- a processing system configured to determine, based on at least one bit in the first frame, one or more resolutions of units of time of a plurality of resolutions of units of time to use for one or more parameter fields to be used in a ranging procedure and to perform the ranging procedure with the wireless node according to the determined one or more resolutions.
A method for wireless communications by an apparatus, comprising:
- generating a first frame providing at least one bit indicating one or more resolutions of units of time of a plurality of resolutions of units of time to use for one or more parameter fields to be used in a ranging procedure performed with a wireless node;
- and
- outputting the first frame for transmission to the wireless node.
