Methods and systems for communicating in a wireless network may use long frames each including an aggregation of medium access control (MAC) protocol data units (MPDUs). In certain embodiments, the first MPDU of a frame may be composed in a format compatible with legacy wireless local area network devices designed to read frames having only one MPDU. A field in the first MPDU may include a duration value which may be used to update a Network Allocation Vector (NAV) of the legacy device to refrain from transmitting for the duration of the long frame. Various other embodiments and implementations are also disclosed. |
