Abstract
Techniques are provided for channel discovery. For example, there is provided a method operable by a mobile entity that may involve measuring beacon signals associated with the network. In one approach, the method may involve, in response to detecting an Authorized Shared Access (ASA) beacon signal on a frequency common to each network entity on a given ASA channel, extracting frequency information from the ASA beacon signal, wherein the ASA beacon signal comprises a single frequency network (SFN) beacon signal. In another approach, the method may involve, in response to detecting an ASA beacon signal on a frequency common to each network entity on a given ASA channel, extract frequency information from the ASA beacon signal, wherein timing correlates with an operating frequency for the ASA beacon signal.
