Patent ID: 7110471

Claim:
A radio communication control device comprising: a demodulation unit configured to demodulate a received signal; a detection circuit, coupled to an output end of the demodulation unit, configured to detect final data contained in a received data stream supplied from the demodulation unit, said detection circuit further configured to output a final data notification signal when detecting the final data; and a standby period timer, coupled to an output end of the detection circuit, configured to set a standby period in accordance with the final data notification signal output from said detection circuit, wherein the received data stream includes, a data section including a plurality of symbols; and a symbol length indicating the number of symbols included in the data section, wherein said detection circuit includes, an arithmetic operation circuit configured to calculate the number of symbols from the symbol length included in the received data stream; a register configured to hold the number of symbols supplied from said arithmetic operation circuit; a counter configured to count the number of symbols included in the received data stream; and a comparator configured to compare the number of symbols counted by the counter and the number of symbols held by the register with each other, said comparator further configured to output the final data notification signal when these numbers coincide with each other, and wherein the standby period timer is further configured to subtract a start delay time of the standby period timer and a delay time for a data transmission process from a standby period defined by a specification, in accordance with the final data notification signal, and is configured to obtain an actual standby period.
