Abstract:
1. A method of managing a wireless network for a location procedure, the method comprising: receiving a location request frame including a location request option sub-element which contains a value for indicating a timing measurement request; transmitting an acknowledgement frame in response to the location request frame; and transmitting a location response frame including a timing measurement sub-element, the timing measurement sub-element comprising: a timestamp difference field containing a time difference between a reception end time of the location request frame and a transmission end time of the acknowledgement frame in response to the location request frame, a timestamp difference units field containing units for the timestamp difference field, and a timestamp difference accuracy field containing an expected standard deviation of the timestamp difference in the units of the timestamp difference units field, wherein the location request frame includes a location parameters element including the location request options sub-element, and wherein the location request options sub-element is a bit-field used to identify a desired location parameters sub-element to be included in the location response frame.
