Abstract

Official abstract text for this publication.

Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal. FIG. 4

First claim

Opening claim text (preview).

What is claimed is: 1. A method of operating a first peer-to-peer communications device to communicate with a second peer-to-peer communications device, said first and second peer-to-peer communications device being in a region including a third peer-to-peer communications device, the method comprising: receiving a presence indicator at said first peer-to-peer communications device communicated over an airlink directly from the second communications device; transmitting a paging…
