Problems solved by technology

A method strictly defines a first group of air link resources reserved for service flows in the first direction and a second group of air link resources reserved for service flows in the second direction, and the first group of air link resources The road resources and the second set of air link resources do not overlap, this method is a waste of resources when the flow level does not match the pre-defined set
A method that allows either of the pair of wireless terminals to send a service request on a shared request resource as needed, which may result in a conflict such that neither request is recovered and / or granted, resulting in the requested service Waste of resources (such as business segments)

Abstract

Methods and apparatus related to the communication of traffic in peer to peer communications are described. A peer to peer communications system includes traffic slots, and for a pair of devices having a connection a first transmission request resource and a second transmission request resource are associated with a traffic transmission interval of the traffic slot, the first request resource preceding the second request resource. The first request resource is used for the first device to communicate a request to transmit traffic to the second device. The second request resource is used to communicate a request from the second device to transmit traffic to the first device. One protocol calls for a second resource request to override a first resource request. In another protocol the second resource is used to communicate additional information corresponding to a first resource request, when a request is communicated in the first resource.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Patent Application No. 11 / 933,009, entitled "METHODS ANDAPPARATUS RELATED TO SIGNALING REQUEST TO TRANSMITTRAFFIC IN A WIRELESS COMMUNICATIONS SYSTEM," filed October 31, 2007, the disclosure of which is hereby incorporated by reference The content is incorporated in its entirety. technical field [0003] Various embodiments relate to methods and devices for wireless communications, and more particularly to methods and devices for use in peer-to-peer wireless communications. Background technique [0004] In a peer-to-peer communication system, a pair of wireless terminals having a connection usually wish to exchange traffic signals. A method strictly defines a first group of air link resources reserved for service flows in the first direction and a second group of air link resources reserved for service flows in the second direction, and the first group of air link resources ...
