摘要： Apparatuses, methods, and computer readable media for setting parameters for joint overlapping basic service set packet detect level and transmit power. An apparatus is disclosed comprising processing circuitry configured to: determine an overlapping basic service set (OBSS) power detect (PD)(OBSS-PD) and a transmit power (TXP) based on first parameters, and if the wireless device has not received a frame from an OBSS master station that does not belong to a same management domain as the wireless device, determine the OBSS-PD and TXP based on second parameters. The second parameters may permit the wireless device to set the OBSS-PD to a higher value without lowering the TXP. The first parameters require that OBSS-PD and TXP be determined based on a minimum OBSS-PD and a maximum TXP, and require the OBSS-PD to be lowered if the TX power is raised.

摘要： Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.

A transmission stage performs at least one iteration of the following steps, for at least one downlink channel: transmitting payload data over the downlink channel, while taking account of the downlink channel estimate; and updating the downlink channel estimate, while taking account of acknowledgment information transmitted by the receiver associated with the downlink channel and acknowledging reception of the payload data.
