Abstract: There is provided a device and method for managing wireless communication over a transmission channel within a network. A set of received signal strength values is obtained for signals transmitted over the transmission channel within the network. A lowest received signal strength value of the set of received signal strength values is determined. A maximum limit by which a transmission power for the transmission channel may be reduced from a predetermined transmission power is determined, the maximum limit being based on the lowest received signal strength value.

Abstract: According to one embodiment, a wireless communication device includes: controlling circuitry configured to change a value of a first parameter in accordance with a history of uplink multi-user transmission or whether capability of uplink multi-user transmission is in an enabled or disabled state, the first parameter defining an upper limit of duration during which a wireless medium is allowed to be occupied; and a transmitter configured to transmit a first frame.

Abstract: According to one embodiment, a wireless communication device includes a transmitter configured to transmit a plurality of first frames by multiplexing, the plurality of first frames each belonging to any one of a plurality of groups; and a receiver configured to receive, at timing not temporally overlapping among the groups, a plurality of second frames which are multiplexed, the plurality of second frames each indicating acknowledgement on the first frame belonging to each group.
