    Abstract: In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ratio transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT, another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.

    Abstract: Embodiments of a system and method for transmitting data from an access point in a multiple user multiple input multiple output (MU-MIMO) system are provided. A first indication of signal quality (ISQ) is received at the access point from a first station and a second ISQ is received from a second station. The access point sets a first power level and a first modulation and coding scheme (MCS) for transmission of a first aggregated media access control (MAC) protocol data unit (A-MPDU) to the first station as a function of the first ISQ and an amount of payload data corresponding to the first A-MPDU. The access point also sets a second power level and a second MCS for transmission of a second A-MPDU as a function of the second ISQ and an amount of payload data corresponding to the second A-MPDU.

    Abstract: A station (STA) may operate as a first peer-to-peer (P2P) client (P2P1) for P2P operations with dual-stage triggering. The STA may decode a primary frame trigger frame (TF) from an access point (AP) operating as a coordinator. The primary TF may allocate resources in an initial portion of a time-duration allocation to the P2P1 for the P2P operations with one or more other peer stations, including a second P2P client (P2P2) and a third P2P client (P2P3). The primary TF may further allocate resources in a subsequent portion of the time-duration allocation to the P2P2 for the P2P operations. The STA may also encode a first secondary TF for transmission within the initial portion of the time-duration allocation. The first secondary TF may allocate specific resource units (RUs) to the one or more other peer stations. The STA may also decode a TB physical layer protocol data unit (TB PPDU) encoded in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format. The TB PPDU may be received concurrently within the initial portion of the time-duration allocation from the one or more other peer stations in accordance with an uplink OFDMA technique.
