    • A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an Ad hoc network comprising a plurality of STAs without an AP where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.

    • 公开了一种使用直接链路建立(DLS)的对等通信系统。 移动站(STA)通过向接入点(AP)(即集中式控制器)发送请求DLS的消息来建立与另一个STA的直接通信链路。 AP可以基于信道测量接受或拒绝DLS请求。 如果DLS请求被接受,则建立DLS使得STA可以直接相互通信。 AP可以将建立的DLS连接拆除,其中包括向一个STA发送包括DLS拆卸请求的消息,或者基于信道测量。 该系统可以是包括多个没有AP的STA的Ad hoc网络,其中每个STA维护一跳和两跳STA的数据库,并且在通知相邻STA之后建立与其他STA的直接链路,以建立 直接沟通链接 (102,104)DLS请求;(106,108)DLS响应;(110)直接通信链路;(112)DLS检测请求;(114)DLS检测响应;(116)DLS测量请求;(118)DLS测量响应 ;(120a,120b)DLS取消
