Method and apparatus for distributing timing information in an asynchronous wireless communication system
First Claim
1. A method for distributing timing information comprising:
- receiving, by an Access Point, a first set of timing information comprising timing information for at least one neighboring Access Point; and
conveying, by the Access Point to a user equipment, a second set of timing information comprising timing information for the at least one neighboring Access Point, wherein the second set of timing information is derived from the first set of timing information.

Abstract
An Access Point (AP) receives a first set of timing information comprising timing information for at least one neighboring AP and conveys, to a user equipment (UE), a second set of timing information comprising timing information for the at least one neighboring AP, wherein the second set of timing information is derived from the first set of timing information. Based on the second set of timing information, the UE is able to determine a time to scan the at least one neighboring AP. In various embodiments of the present invention, the AP may receive the first set of timing information from another UE or may receive the timing information without the involvement of the another UE, for example, via a network interconnecting the APs or by monitoring an air interface of the at least one neighboring AP.
