Abstract: Mobile nodes support simultaneous OFDM links with multiple points of network attachment. A MN may simultaneously use multiple IP addresses, allowing packets addressed to the mobile to be routed over different paths. Alternatively, the MN may have a single IP address with packets corresponding to different applications, e.g., identified by packet header information, being routed over different paths. Thus packets corresponding to one application, e.g., a voice application, may be routed over one wireless link while packets corresponding to another application, e.g., a data application such as E-mail, may be routed over another wireless link, while packets corresponding to still another application, e.g., a broadcast TV service may be communicated over another wireless link. The direction of communication, latency, reliability and other QoS characteristics of the different wireless links may be considered in path selection to provide MN's user with cost effective service while still meeting minimum application requirements.

Abstract: Methods and apparatus for supporting peer to peer and infrastructure e.g. cellular communication in a multimode device which can operate in a cellular system are described. Methods and apparatus for supporting peer to peer devices are also described. Peer to peer communication occurs within a switching time period during which infrastructure signaling does not occur and devices switch between an uplink and a downlink mode of infrastructure operation. The time period set for the switching time period is intentionally set larger e.g. 10 50 100 or even more times larger than that required based on maximum cell size. Thus a peer to peer communications period can be introduced into a TDD system and use the same frequency band as the TDD system in a manner that can remain compliant with a cellular communications protocol which allows for a switching time period e.g. set in the system by a parameter.
