System and method for enabling operations based on distance to and motion of remote device

摘要

Various operations may be performed based on a distance-related function associated with two or more devices. For example, an association procedure for two or more devices may be based on one or more determined distances. Similarly, presence management may be based on one or more determined distances. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

主权项

1. A first device for wireless communications, comprising:
a receiver configured to receive a first signal and a set of signals from a second device by way of a wireless medium; an indication generator configured to:
generate a first indication of a distance between the first device and the second device based on the first signal;generate a set of indications of distinct distances between the second device and the first device based on the set of signals;generate a second indication of a relative motion between the first device and the second device based on the set of indications;generate a third indication of a time of actuating a first switch on the first device;generate a fourth indication of a time of actuating a second switch on the second device; and a processor configured to perform an operation based on the first, second, third and fourth indications.
