1. A method comprising:
- sending a message from a first node to one or more other nodes in a wireless network indicating that the first node is configured to perform a scanning operation on a wireless medium in substitution of scanning the wireless medium at the one or more other nodes;
wherein sending the message indicating that the first node is configured to perform a scanning operation comprises sending an information element, wherein the information element includes;
a scanning counter field that includes a counter value that indicates a number of superframes since a last scanning operation or a number of superframes before a next scanning operation at the first node.

Abstract
Various embodiments are described relating to sharing scanning operations among nodes in a wireless network, such as a WiMedia ultra-wideband (UWB) network. In an example embodiment, a message may be sent from a first node to one or more other nodes in a wireless network indicating that the first node is configured to perform a scanning operation on a wireless medium in substitution of scanning the wireless medium at the one or more other nodes. The wireless medium may be scanned, for example, by the first node to obtain scanning results for the one or more other nodes. The scanning results may be sent, for example, by the first node, to the one or more other nodes.

22. An apparatus for wireless communications, the apparatus comprising:
-
a controller; a memory coupled to the controller; and a wireless transceiver coupled to the controller;
the apparatus adapted to;send a message via the wireless transceiver to indicate that the apparatus is configured to perform a scanning operation on a wireless medium in substitution of scanning the wireless medium at any of one or more devices receiving the message; wherein the message includes an information element; and wherein the information element includes; a scanning zone field that includes an indication of one or more portions of a plurality of portions of a superframe scanned by the apparatus or an indication of one or more apparatus subgroups of a plurality of groups of a superframe scanned by the apparatus. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
