Device for round trip time measurements
First Claim
1. An apparatus for facilitating localization of a station (STA) in a short-range wireless network, the apparatus comprising:
- a radio frequency (RF) interface; and
a media access control (MAC) section coupled to the RF interface;
wherein the MAC section is configured to;
receive a request over the RF interface from the STA for a measurement related communication;
generate and transmit over the RF interface an automatic response to the received request immediately after a uniform period is established so as to be uniform among the apparatus and any other ones of the apparatus within the network, wherein the automatic response is for generating a round-trip time (RTT) for localization; and
perform only the generation of the automatic response.

Abstract
An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.

12. An apparatus for providing localization in a short-range wireless network, the apparatus comprising:
-
transceiver means for receiving a request from a station (STA) for a measurement related communication and for transmitting an automatic response to the request for the measurement related communication, wherein the automatic response is for generating a round-trip time (RTT) for localization; and media access control (MAC) means coupled to the transceiver means, the MAC means for; recognizing the request for the measurement related communication, the request recognized based on an identifier associated with the apparatus and a request type of the request; and causing the transceiver means to immediately generate the automatic response after a uniform period associated with recognizing the request, the uniform period uniform in the apparatus and in any other ones of the apparatus within the network, the transceiver means generating only the automatic response. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method for providing localization in a short-range wireless network, the method comprising:
-
receiving a request from a station (STA) for a measurement related communication at a plurality of dedicated network apparatuses in the short-range wireless network; recognizing the request for the measurement related communication at the plurality of dedicated network apparatuses; immediately transmitting to the station an automatic response from the plurality of dedicated network apparatuses after a uniform processing delay associated with each of the plurality of dedicated network apparatuses, wherein the automatic response is for generating a round-trip time (RTT) for localization; and localizing the STA based on different times of arrival of respective ones of the automatic response from corresponding ones of the plurality of dedicated network apparatuses. - View Dependent Claims (22, 23, 24, 25)

26. A non-transitory computer-readable medium having instructions thereon for providing localization in a short-range wireless network, the instructions, when read and executed by a processing unit, perform operations, the instructions comprising:
-
code to provide an automatic response to a request for a measurement related communication in the short-range wireless network; code to receive a request from a station (STA) for a measurement related communication; code to transmit to the station an automatic response to the received request for the measurement related communication immediately after a uniform delay for processing of the request and the automatic response, the uniform delay uniform among any elements within the network that are capable of providing the automatic response, wherein the automatic response is for generating a round-trip time (RTT) for localization; and code to perform only the generation of the automatic response. - View Dependent Claims (27, 28, 29)
