Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP / CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP / PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

A scheduler associated with a base station of a wireless communication network dynamically compensates for uplink bandwidth that has been re-assigned (stolen) by a mobile station (MS) to transmit a control message. The scheduler allocates a preset amount of bandwidth to the MS for data transmission. The scheduler detects bandwidth stealing activity and evaluates when bandwidth stealing is justified on he part of the MS. The scheduler provides additional bandwidth to appropriately compensate for the stolen bandwidth when bandwidth stealing is justified, in order to maintain the quality of service of the data traffic connection.
