Abstract: A power-save system for a network with an access point and an associated power-save client. The access point buffers wireless data that includes a unicast frame and a multicast frame. A periodic scheduled beacon message is transmitted with a unicast indication element and a multicast indication element. The unicast element instructs a client to remain awake to receive a buffered unicast frame, which includes a destination MAC address. The multicast element instructs a client to remain awake following the beacon to receive a buffered multicast frame, which includes a destination multicast address designating a multicast group of which the client is a member. At least one beacon message is designated as a multicast delivery beacon. The buffered multicast frame is transmitted following the designated multicast beacon. The multicast element contains a list of entries, each entry corresponding to either a multicast MAC address, multicast IP address, or client identifier.

Abstract translation: 具有接入点和相关节电客户端的网络的省电系统。 接入点缓冲包括单播帧和多播帧的无线数据。 用单播指示单元和组播指示单元发送周期性调度信标消息。 单播元件指示客户端保持唤醒以接收包括目的地MAC地址的缓冲单播帧。 多播单元指示客户端在信标之后保持清醒以接收缓冲的多播帧，其包括指定客户端是其成员的多播组的目的地多播地址。 至少一个信标消息被指定为多播递送信标。 缓冲的多播帧在指定的多播信标之后发送。 组播元素包含条目列表，每个条目对应于组播MAC地址，组播IP地址或客户端标识符。
