摘要： A protocol for a peer power save mode (PPSM) in a tunneled direct link setup (TDLS) wireless network and a system therefor are provided. A station (STA) set up a TDLS link can send a frame having a power management bit set to a peer STA to enter into a power save mode (PSM). In this case, the station entering into the PSM operates in a PPSM client mode. When the peer STA operates in the PPSM client mode, the STA can operate in the PPSM access point (AP) mode or can enter into the PPSM client mode. The STA operating in the PPSM AP mode buffers data for the STA operating in the PPSM client mode and informs the peer STA of information indicating that there is buffered data by the use of a peer traffic indication frame or the like. In principle, a U-APSD procedure can be applied to the transmission of data through a direct link from the STA operating in the PPSM AP mode to the STA operating in the PPSM client mode.
摘要翻译：提供了一种用于隧道直接链路建立（TDLS）无线网络中的对等节电模式（PPSM）协议及其系统。建立TDLS链路的站（STA）可以将具有设置的功率管理位的帧发送到对等STA进入省电模式（PSM）。在这种情况下，进入PSM的电台以PPSM客户端模式运行。当对等STA以PPSM客户端模式运行时，STA可以在PPSM接入点（AP）模式下工作，或者可以进入PPSM客户端模式。以PPSM AP模式运行的STA缓冲以PPSM客户端模式运行的STA的数据，并通过使用对等体流量指示帧等向对等STA通知指示存在缓存数据的信息。原则上，U-APSD程序可以应用于通过从在PPSM AP模式中操作的STA到在PPSM客户端模式下操作的STA的直接链路的数据传输。
