Abstract
Official abstract text for this publication.
A method including receiving a signal from a terminal; measuring channel state information (CSI); comparing the CSI to determine whether to decode the received signal; and if it is determined to decode the received signal, removing noise by decoding the received signal, and then performing decode and forward (DAF) in which the signal is re-encoded, and if it is determined not to decode the received signal, performing amplify and forward (AAF) in which the received signal is amplified. The CSI may be at least one of a frame error rate (FER), a bit error rate (BER), a signal to noise ratio (SNR), and a signal to interference plus noise ratio (SINR). Accordingly, a time delay consumed for channel decoding in hybrid DAF coordinated communication is decreased, data transmission and resource usage is more effectively achieved in coordinated communication using multiple terminals, and unnecessary power consumption is decreased.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of performing coordinated communication by a relay station, the method comprising: receiving a signal from a terminal, wherein the signal is encoded into a low density parity check (LDPC) code; measuring channel state information (CSI) indicating a state of a channel which receives the signal; comparing the CSI with a predetermined threshold to determine whether to decode the received signal; when it is determined to decode the receive…
