Abstract:
1. A method of transmitting data in a wireless mesh network, the method comprising: establishing a mesh peer link with a mesh point (MP); generating an aggregate-medium access control service data unit (A-MSDU) including a plurality of A-MSDU sub-frames; and transmitting the A-MSDU to the MP through the mesh peer link, wherein each of the plurality of A-MSDU sub-frames comprises a sub-frame header unit, an MSDU unit containing mesh data, and a padding unit for making each of the plurality of A-MSDU sub-frames a multiple of 4 octets in length, wherein the sub-frame header unit comprises a mesh destination address (DA) field containing a medium access control (MAC) address of a destination MP of the mesh data contained in the MSDU unit, a mesh source address (SA) field containing a MAC address of a source MP of the mesh data contained in the MSDU unit, and a mesh header field, wherein the mesh header field comprises a mesh flags subfield, a mesh time-to-live (TTL) subfield, a sequence number field and an address extension subfield, the mesh flags subfield including an address extension mode subfield indicating contents of the address extension subfield, the mesh TTL subfield indicating a remaining number of hops that the corresponding A-MSDU sub-frame is forwarded, the sequence number field being used for filtering duplicate reception of the corresponding A-MSDU sub-frame, and the address extension subfield is for a mesh address extension of the corresponding A-MSDU sub-frame, and wherein the mesh DA field, the mesh SA field, the mesh flags subfield, the mesh TTL subfield, the sequence number field and the address extension subfield are configured sequentially in the subframe header unit.
