LAYERED RETRANSMISSION APPARATUS AND METHOD, RECEPTION APPARATUS AND RECEPTION METHOD
First Claim
1. A retransmission apparatus for retransmitting information received from a base station to a reception apparatus, the apparatus comprising:
- a reception unit configured to receive information regarding a plurality of layers from the base station;
determining unit configured to determine retransmission control information including at least one layer to be retransmitted among the plurality of layers based on feedback information received from the reception apparatus; and
a transmission unit configured to retransmit the at least one layer information to the reception apparatus based on the results of the determining unit.
