Abstract: Computer readable media, methods, and apparatuses for flow control with acknowledgment feedback. An apparatus of a wireless device comprising: memory; and processing circuitry coupled to the memory is disclosed. The processing circuity may be configured to determine based on buffer capacity parameters of a station and a receive buffer state of the station at least one of a size, a modulation and coding scheme (MCS), a bandwidth of a subchannel, or a number of spatial streams (NSS) for a frame. The processing circuitry may be further configured to encode the frame based on the size, the MCS, the bandwidth of the subchannel, and the NSS. The processing circuitry may be further configured to configure the wireless device to transmit the frame in accordance with the size, the MCS, the bandwidth of the subchannel, the NSS, and one or both of orthogonal frequency division multiple-access (OFDMA) or multi-user multiple-input multiple-output (MU-MIMO).

Abstract: Embodiments for an access point (AP) and method for communication in a basic service set (BSS) of a management domain are generally described herein. The AP may be configured to maintain a list of BSSs that belong to the management domain and retrieve, for a station (STA) configured to perform spatial reuse over overlapping basic service set (OBSS) physical layer convergence protocol (PLCP) protocol data units (OBSS PPDUs) belonging to OBSSs from the management domain, at least one parameter for a spatial reuse rule that proportions overlapping basic service set packet detection levels (OBSS_PD) and transmit power (TxPower) levels for the STA. In an embodiment, the AP may retrieve, for a STA configured to perform spatial reuse over OBSS PPDUs not belonging to OBSSs from the management domain, default parameters for a spatial reuse rule that proportions OBSS_PD and TxPower levels for the STA and encode, for transmission to the STA belonging to the OBSSs from the management domain, an indication of the at least one parameters, and encode, for transmission to the STA not belonging to OBSSs from the management domain, an indication of the default parameters.

Abstract: In a dense wireless environment with spatial diversity and with multiple access points (APs) and multiple users (STAs), a common network controller may be used to determine which AP-STA combinations can operate simultaneously over the same channel without interfering with other AP-STA combinations. Each STA associates with each AP in a way that derives directionality, signal strength, array weight vectors, etc., for that AP and then provides that information to that AP. Each AP collects similar information from every STA in the network, and forwards the collected information to a Central Controller, who uses the combined information from all APs to determine which AP-STA combinations may operate simultaneously without causing interference with each other.

Abstract: A transmit power restriction period during which lower power transmissions may occur simultaneous with reception of other frames improves reuse of a wireless medium. In some aspects, a method includes continuing, by a wireless device, a back-off procedure when a first frame originating from outside a basic service set of the wireless device is received if a received energy of the first frame is below a threshold. Upon completion of the back-off procedure, a second frame may be transmitted at a reduced power level to avoid interfering with the first frame. The reduced transmit power level may be maintained for at least a predetermined time period or an end of a transmission opportunity of the wireless device, whichever is longer. Maintaining the reduced transmit power for the predetermined time period may prevent a subsequent transmission by the wireless device from unduly interfering with the first frame.
