Patent ID: 8229353

Claim:
A wireless communication system, comprising: a first device configured to repeatedly transmit data within a specific transmission time; and a second device configured to perform intermittent reception by repeating a specific reception duration at a constant period, so as to receive the data from the first device, wherein the second device includes: a transceiver configured to transmit and receive the data transmitted to and from the first device; a data detector configured to detect whether or not the transceiver has received the data from the first device; a data error detector configured to determine whether or not there is an error in the data received by the transceiver; a reception duration controller configured to change the specific reception duration; and a time determiner configured to output a timeout signal to the reception duration controller when the data detector has not detected a reception of the data for at least a specific time, wherein, when the data error detector determines that there is the error in the data received by the transceiver, the reception duration controller extends the specific reception duration of the transceiver, so as to receive second data that is newly sent from the first device after the data having the error, and wherein the reception duration controller repeatedly extends the specific reception duration of the transceiver until the timeout determiner outputs the timeout signal to the reception duration controller or until the data error detector determines that there is no error in the second data or any data received after the data having the error.
