1. An apparatus, comprising:
a first station adapted for communications in a wireless network that operates in compliance with Standards 802.11, promulgated by the Institute of Electrical and Electronics Engineers (IEEE 802.11); wherein the IEEE 802.11 standards define a High Throughput Control (HTC) field used for signaling such that the HTC field can be transmitted as part of a control frame and defines that a receiving station shall assert a network allocation vector (NAV) in response to receiving a frame of a type indicative of a management frame, data frame, or a control frame; and wherein the first station is configured to use a frame with a first subtype and is constructed to deliver an HTC field within a Control Frame (Control Frame +HTC) to receiving stations conforming to an IEEE 802.11 standard, thereby enabling receiving stations compliant with the IEEE 802.11 standard to be able to assert the network allocation vector (NAV) in a duration field of the frame. |
