Embodiment Construction

[0041] 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.

[0042] 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 ite...

Abstract

Methods and apparatus involving peer-to-peer communication networks are described. Wireless communications devices support peer-to-peer communications with multiple peers. Wireless communications devices determine their transmission timing synchronization based on reference signals received from nodes such as base stations, satellites, or beacon transmitters that do not transmit user data. The wireless communications device determines a plurality of different reception timing adjustments corresponding to different peer-to-peer communications devices based on signals received from those peer-to-peer communications devices. The wireless communications device stores a plurality of determined reception timing adjustment information corresponding to different peer-to-peer communications devices. The wireless communications device obtains and applies stored receive timing adjustment information that matches the specific device that sent the signal it is attempting to recover.

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 if a certain level of device synchronization and / or predictability could be achieved so that peer devices could anticipate when certain activities were performed by other peer devices, where such Allows peers to operate in organized and / or loosely synchronized modes for specific activ...
