Abstract
An access node receives a device beacon transmitted from a wireless communication device in accordance with a system timing of a wireless wide area network (WWAN). When transmitted within a WWAN uplink channel, the device beacon is mapped to designated beacon channels within the time-frequency space of the uplink WWAN channel assignment. In response to the reception of the device beacon, communications between the wireless communication device and the access node are established. In one example, the access node is a femtocell base station. In another example, the access node is a wireless local area network (WLAN) access point.
