Communication relay apparatus and communication relay method
First Claim
1. A communication relay apparatus, comprising:
- a first determining section that determines a first received quality of a whole of a received signal comprising a plurality of elements;
a first relay section that relays the whole of the received signal according to a first determination result of the first determining section;
a second determining section that determines a second received quality of the received signal per element; and
a second relay section that relays a specific element of the received signal according to a second determination result of the second determining section, wherein;
when the first received quality is equal to or higher than a first predetermined level, the first relay section determines the received signal as a relay target; and
the second relay section determines, as the relay target, an element out of the received signal which is not the relay target of the first relay section, the element having the second received quality equal to or higher than a second predetermined level.

Abstract
A communication relay apparatus wherein the error rate characteristic of a relay destination is improved to raise the throughput, while reducing the given interference power to prevent the reduction of the throughput of the whole communication system. In the apparatus, a signal addressed to a base station is received (ST1010), and a decoding process and other processes are performed (ST1020). A bit error determination is performed (ST1030), and if there is no bit error, a reproduction/relay process (ST1050) is performed. If there is any bit error, a threshold-based determination of reception quality is performed for each of subcarriers (ST1120-1130). If the reception quality is greater than a threshold value, the corresponding subcarrier is outputted (ST1140); otherwise, the corresponding subcarrier is not relayed (ST1150). A signal, which has been subjected to either process, is transmitted (ST1060).
