REPLAY METHOD, COMMUNICATION SYSTEM AND COMMUNICATION APPARATUS
First Claim
1. A reply method in which a signal is transmitted from a first communication apparatus to a second communication apparatus in one of a plurality of time frames contained in each of radio frames and in which the second communication apparatus replies to the first communication apparatus with information indicating whether or not the signal has been successfully decoded, the method comprising:
- transmitting, by the first communication apparatus, signals to the second communication apparatus in a plurality of frequency bands in an identical time frame;
receiving, by the second communication apparatus from the first communication apparatus, the signals transmitted in the plurality of frequency bands in the identical time frame;
generating, by the second communication apparatus, a reply signal for a signal received in each of the plurality of frequency bands, the reply signal indicating whether the received signal has been successfully decoded; and
transmitting, by the second communication apparatus, a plurality of the reply signals separately in a plurality of time frames, each of the plurality of reply signals being generated for each of signals received in the plurality of frequency bands in the identical time frame.
