APPARATUS AND METHOD FOR CONTROLLING DECODING

摘要

A method and an apparatus are provided for determining a downlink control indicator (DCI) at a receiver. A signal is received at the receiver. The receiver measures channel quality based on the received signal. Signals of physical downlink control channel (PDCCH) areas that correspond to each channel format indicator (CFI) in the received signal are decoded, if a measurement of the channel quality is not a configuration condition. The receiver obtains the CFI by decoding a physical control format indicator channel (PCFICH) of the received signal, if the measurement of the channel quality is the configuration condition. The receiver determines the DCI based on the decoded signals.

1. A method of determining a downlink control indicator (DCI) at a receiver, the method comprising:
receiving a signal at the receiver; measuring, by the receiver, channel quality based on the received signal; decoding signals of physical downlink control channel (PDCCH) areas that correspond to each channel format indicator (CFI) in the received signal, if a measurement of the channel quality is not a configuration condition; obtaining, by the receiver, the CFI by decoding a physical control format indicator channel (PCFICH) of the received signal, if the measurement of the channel quality is the configuration condition; and determining, by the receiver, the DCI based on the decoded signals or the decoded PCFICH.
