Patent ID: 8116273

Claim:
A method for transmission of a packet using a plurality of Frequency Allocations (FAs) in a wireless Orthogonal Frequency Division Multiplexing (OFDM) communication system, the method comprising: interleaving a packet to re-arrange each of a plurality of parts of the packet according to a first read-out order; mapping the plurality of parts of the packet to at least one of the plurality of FAs based on a result of the interleaving; when a re-transmission request is received, interleaving the packet to re-arrange each of the plurality of parts of the packet according to a second read-out order that is different from the first read-out order; re-mapping the plurality of parts of the packet to at least one of the plurality of FAs based on a result of the interleaving for re-transmission such that at least one of the plurality of parts of the packet is re-mapped to an FA that is different than an FA previously mapped thereto; and transmitting the re-mapped plurality of parts of the packet through the plurality of FAs at least one corresponding FA by using at least one of a plurality of radio frequency (RF) transmitters, each FA corresponding to a different RF transmitter such that parts of the packet that are transmitted through different FAs pass through different RF transmitters.
