An apparatus, method, and computer readable media for requesting and sending block acknowledgement requests (BARs) and block acknowledgments (BAs) is disclosed. A method for BARs is disclosed. The method may include transmitting data frames to two or more wireless communication devices in accordance with a multi-user multiple-input and multiple-output (MU-MIMO). The method may include transmitting block acknowledgement requests (BARs) for the transmitted data frames to the two or more wireless communication devices in accordance with MU-MIMO. The method may include receiving block acknowledges (BA) of the data frames from the two or more wireless communication devices in accordance with MU-MIMO. A method for BAs is disclosed. The method may include receiving data frames from a second wireless communication device. The method may include receiving a block acknowledgement request from the second wireless communication device The method may include sending a block acknowledgement to the second wireless communication device using MU-MIMO.

Wireless device, method, and computer readable media for requesting and sending block acknowledgement

Some wireless communications environments, such as Wi-Fi, may include inexpensive power amplifiers where the power adjustment may not be accurate, and may also include pathloss measurement errors that are high enough to degrade performance of a power control algorithm. To address this issue, an exemplary aspect is directed toward a finite state power control algorithm and technique that, while designed for next generation Wi-Fi standards, such as 802.11ax, can in general be used with any wireless communication protocol or standard.

Scheme of finite power transmission statuses for low cost wireless broadband communication system

Some demonstrative embodiments include devices, systems and methods of multi-user uplink transmission. For example, an apparatus may include a transmitter to transmit a multi-user (MU) downlink transmission to a plurality of wireless stations; a receiver to receive from the plurality of wireless stations a plurality of acknowledgement (ACK) frames, at least one ACK frame from at least one wireless station including an uplink scheduling request indicating uplink resources requested by the wireless station; and a scheduler to schedule an uplink transmission from the at least one wireless station based on the uplink scheduling request, the transmitter to transmit at least one scheduling frame including scheduling information of the scheduled uplink transmission.
