Abstract: 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.

Abstract: Techniques for improving observed time difference of arrival (OTDOA) positioning are discussed. One example apparatus employable in an eNB comprises a processor, transmitter circuitry, and receiver circuitry. The processor is configured to: generate a set of positioning reference signals (PRSs); and encode the set of PRSs for a multi-antenna transmission. The transmitter circuitry is configured to transmit the set of PRSs via the multi-antenna transmission. The receiver circuitry is configured to receive a set of reference signal time differences (RSTDs) from a user equipment (UE) in response to the set of PRSs. The processor is further configured to estimate a position of the UE based at least in part on the set of RSTDs.

Abstract: Some demonstrative embodiments include devices, systems and methods of multi-user downlink transmission. For example, an apparatus may include a transmitter to transmit a multi-user (MU) downlink request to a plurality of wireless stations; and a receiver to receive one or more responses from one or more wireless stations of the plurality of wireless stations, wherein the transmitter is to transmit to the plurality of wireless stations a MU scheduling message indicating resources allocated to a downlink transmission to at least one scheduled station of the one or more wireless stations, and to transmit the downlink transmission to the at least one scheduled station according to the MU scheduling message.
