Patent ID: 8335184

Claim:
A wireless base station for allocating a wireless bandwidth to a wireless terminal based on a bandwidth request from the wireless terminal, comprising: a receiver configured to receive a target data transmitted in the allocated wireless bandwidth from the wireless terminal, the target data including one or more user packets on which a combining process or a dividing process is performed and control information indicating the combining process or the dividing process; and a processor configured to increase or reduce the total quantity of the bandwidth request depending on the control information indicating whether the combining process or the dividing process is performed on the one or more user packets; wherein the processor is configured to either subtract a data quantity equivalent to an overhead omitted by the combining process from the bandwidth request quantity or add a data quantity equivalent to an overhead generated by the dividing process to the bandwidth request quantity, wherein the data quantity equivalent to the overhead is expressed as “N×PSH−(N−1)×(H+T)” in a case of the combining process and expressed as the data quantity equivalent to the overhead is expressed as “2×FSH+H+T”, wherein, “N” indicating the number of user packets, “PSH” indicating a data quantity of the subheader corresponding to combined user packets, “H” indicating a data quantity of a header of the user packets, and “T” indicating a data quantity of a trailer of the user packets, wherein “FSH” indicating a data quantity of the subheader corresponding to divided user packets.
