Abstract: A method includes receiving, at a station, a first delivery traffic indication message (DTIM) assigned to a first delivery interval. The first DTIM is configured to indicate whether group-addressed traffic is scheduled for delivery during a beacon interval. The first delivery interval is larger than a second delivery interval associated with a second DTIM. The method further includes receiving the group-addressed traffic during the beacon interval.

Abstract: Embodiments disclosed herein for MAC processing for efficient use of high throughput systems and that may be backward compatible with various types of legacy systems. In one aspect, a data transmission structure comprises a consolidated poll and one or more frames transmitted in accordance with the consolidated poll. In another aspect, a Time Division Duplexing (TDD) data transmission structure comprises a pilot, a consolidated poll, and zero or more access point to remote station frames in accordance with the consolidated poll. In one aspect, frames are transmitted sequentially with no or substantially reduced interframe spacing. In another aspect, a guard interframe spacing may be introduced between frames transmitted from different sources, or with substantially different power levels. In another aspect, a single preamble is transmitted in association with one or more frames. In another aspect, a block acknowledgement is transmitted subsequent to the transmission of one or more sequential frames.

Abstract translation: 本文公开的用于MAC处理的实施例用于高吞吐量系统的有效使用并且可以向后兼容各种类型的传统系统。 一方面，数据传输结构包括合并轮询和根据综合民意调查发送的一个或多个帧。 另一方面，根据综合民意调查，时分双工（TDD）数据传输结构包括导频，综合轮询以及到远程站帧的零个或多个接入点。 在一个方面，帧以没有或基本上减小的帧间间隔顺序传送。 在另一方面，可以在从不同源发送的帧之间或具有基本上不同的功率电平的情况下引入保护帧间间隔。 在另一方面，与一个或多个帧相关联地发送单个前同步码。 在另一方面，在发送一个或多个顺序帧之后发送块确认。
