Abstract: A method performed by a first wireless access point for coordinating a multi-access point transmission in a wireless network of multiple access points includes receiving an indication of a transmit opportunity for the first wireless access point, transmitting at least one indication frame to the multiple access points comprising information related to the transmit opportunity, receiving at least one request frame from one or more access points of the multiple access points indicating participation with the transmit opportunity, and transmitting a trigger frame to the one or more access points that indicated participation with the transmit opportunity, wherein the trigger frame comprises information indicating respective power levels for the participating access points. The shared transmit opportunity may then be used to transmit downlink data to associated stations of the first wireless access point and the other participating access points during the transmit opportunity.

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.

Abstract: A method to transmit data from a wireless apparatus includes determining an information block length corresponding to an error correction code, inserting padding bits into at least one protocol data unit, PDU, of a plurality of PDUs such that a padded PDU size is an integer multiple of the determined information block length, and wherein each PDU in a frame of PDUs to be transmitted comprises a PDU size that is an integer multiple of the determined information block length, and transmitting the frame encoded by the error correction code with the determined information block length to a wireless receiver.
