Abstract
In one embodiment, in absence of transmitting from an apparatus a reservation request frame, the apparatus receives a reservation response frame on an assigned channel. The reservation response frame indicates a duration of a frame transmission. In response to receiving the reservation response frame, the apparatus transmits a frame on the assigned channel during the frame transmission. In another embodiment, in response to receiving a reservation request frame on a first channel at an apparatus, the apparatus transmits a reservation response frame on the first channel and on at least one second channel. The reservation request frame indicates a duration of a frame transmission. The reservation response frame indicates the duration of the frame transmission. After transmitting the reservation response frame, this apparatus receives during the frame transmission a first frame on the primary channel and a second frame on the at least one secondary channel.
