Abstract
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.
Claims21
A method of communicating in a wireless network, the method comprising:
- transmitting an aggregate frame composed of a plurality of medium access control (MAC) Protocol Data Units (MPDUs) wherein a first MPDU of the aggregate frame has a format readable by a legacy wireless local area network (WLAN) device which can only read frames having a single MPDU.
An apparatus for use in a wireless network, the apparatus comprising:
- a processing circuit to form a frame comprising a plurality of MAC protocol data units (MPDUs) wherein a first MPDU of the frame includes a duration value identifying a duration of the frame.
A system for use in a wireless network, the system comprising:
- a processing circuit to generate frames, each frame comprising a header and a plurality of medium access control (MAC) Protocol Data Units (MPDUs), wherein the header of each frame includes a value identifying a length of only a first MPDU of the frame;
- a radio frequency (RF) interface communicatively coupled with the processing circuit;
- and
- at least two dipole antennas coupled with the RF interface for multiple input multiple output (MIMO) communications.
