PROBLEM TO BE SOLVED: To improve battery saving efficiency by applying the intermittent reception control to a receiving frame at every block. SOLUTION: A block reception-decision flag P is initialized in an initialization mode. When the first receiving frame F1 is received, the intermittent reception control is carried out, based on the flag P and via the on/off actions of a receiver. As an initialized block reception decision flag P0 is first referred to, the reception control is performed to turn on the receiver with the timing when all the blocks of the frame F1 can be received. Then the information received at first time on the frame F1 is stored. Thus, a block reception-decision flag is produced at every block of a receiving frame, based on the received and unreceived information. Then the intermittent reception is controlled in every block, based on the block reception decision flag when the next frame is received. |
