Embodiment Construction

[0042] figure 1 is a diagram of an exemplary recurring peer-to-peer communication system timing structure 100 in accordance with various embodiments. The exemplary timing structure 100 includes a number of different types of slots, including: peer discovery slots, timing synchronization slots, paging slots, and traffic slots. In some embodiments, a timing synchronization slot is included as part of a peer discovery slot. In some other embodiments, the timing synchronization slots do not overlap with the timing synchronization slots, eg, the timing synchronization slots follow the peer discovery slots.

[0043]The first iteration of the exemplary recurring peer-to-peer communication system timing structure 100 begins with a time marker reference 102 with a timing structure repetition interval 122 including: peer discovery slot 104, timing synchronization slot 106, paging time slot 108, traffic slot 110, traffic slot 112, paging slot 114, and traffic slot 116. The second iter...

Abstract

Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes recurring peer discovery intervals and traffic intervals. During a peer discovery interval, a wireless communications device, supporting peer to peer communications, monitors for and receives a broadcast signal from another peer wireless communications device, recovers an identifier from the received broadcast signal, and stores the received identifier in memory. The identifier is one of a device identifier and a user identifier. The wireless communications device maintains a list of discovered identifiers in its vicinity. In some embodiments, paging intervals are also included in the recurring peer to peer timing structure. In various embodiments, a wireless communications device receives or sends a page to a peer node prior to sending or receiving user data in a traffic interval. Various features are directed to peer paging protocol implementations.

Description

technical field [0001] Embodiments relate to methods and apparatus for wireless communications, and more particularly, to methods and apparatus for use in peer-to-peer wireless communications. Background technique [0002] Wireless communication devices are ubiquitous. Many cellular systems use a centralized controller and / or other network-based control mechanisms to control the operation of wireless devices so that the cellular devices operate in an efficient and relatively synchronized manner. Unfortunately, in peer-to-peer systems, such centralized control and / or network-based synchronization mechanisms are often lacking. [0003] In the case of a peer-to-peer system, it would be desirable that, if a peer device is able to discover that there are other peer devices in the vicinity, then use this knowledge to make communication and / or paging decisions. It would also be desirable if peer devices are able to operate in a loosely synchronized and / or predictable manner when ...
