Abstract

Methods and apparatus are described herein for dynamic allocation of multiple channels and data streams for multi-channel transmission and multiple-input and multiple-output (MIMO). For example, a station (STA) may receive an enhanced poll (EPoll) frame that includes a time offset, a channel offset and antenna/sector settings from an access point (AP). The STA may transmit, based on the received EPoll frame, an enhanced service period request (ESPR) frame that includes a MIMO control field and a multi-channel control field. The MIMO control field may indicate whether the STA supports MIMO transmission. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Upon transmitting the ESPR frame, the STA may receive an enhanced grant frame from the AP. The enhanced 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.
