Abstract:
1. A wireless communication terminal comprising: a receiver that receives a physical packet, the physical packet including at least one frame body field, at least one first field including information on a length of the frame body field, at least one second field used for error detection of the frame body field, and at least one sequence number field including a sequence number corresponding to the frame body field; a first processor that extracts a correct frame body field using the first field and the second field; a buffer that retains the frame body field extracted by the first processor and the sequence number field corresponding to the frame body field; a memory that updates and retains a successively and successfully received maximum sequence number based on a result of the first processor; a second processor that transfers the frame body fields corresponding to the sequence numbers up to the successively and successfully received maximum sequence number retained in the memory from the buffer to a continued reception process; and a transmitter that obtains the successively and successfully received maximum sequence number retained in the memory and transmits, in response to an instruction to transmit the response frame from the second processor, a response frame indicating the maximum sequence number; wherein when at least one correct frame body field has been extracted by the first processor, the second processor determines that the response frame is to be transmitted, and issues the instruction to the transmitter upon completion of a process in the first processor with respect to the physical packet.
