Communication system, transmitter, receiver, and communication method

摘要

The communication system comprises a transmitter (1A) and a receiver (2A). Both, the transmitter (1A) and the receiver (2A) are capable of operating in a normal mode or a compressed mode in which setting of a predetermined idle time is allowed. The transmitter (1A) effects transmission power control to a frame in each mode. When operating in the compressed mode, the transmitter (1A) changes a position of the idle time in such a manner so as to minimize adverse affect of a transmission power control error that occurs after the idle time.
