Zusammenfassung:	Methods and apparatus for dynamically allocating multiple channels and data streams for multi-channel transmission and multiple input multiple output (MIMO) are described herein. For example, a station (STA) may receive an enhanced polling (E polling) frame from an access point (AP), including a time offset, a channel offset, and an antenna/sector setting. The STA may transmit an enhanced service period request (ESPR) frame including a MIMO control field and a multi-channel control field based on the received E-poll frame. The MIMO control field may indicate whether the STA supports MIMO transmission or not. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Once the ESPR frame is transmitted, the STA may receive an enhancement grant frame from the AP. The enhancement grant frame may include an antenna configuration and a multi-channel allocation to enable the STA to perform the MIMO transmission and the multi-channel transmission. 本文描述了用于动态分配用于多信道传输和多输入多输出(MIMO)
