A communication method performed by a User Equipment (UE), comprising:
- receiving, by the UE, information about one or more serving cells configured for the UE;
- receiving, by the UE, data using the one or more serving cells configured for the UE, wherein each of the one or more serving cells configured for the UE supports one of a plurality of transmission modes and each of the plurality of transmission modes supports on or two transmission blocks;
- generating, by the UE, acknowledgement/negative-acknowledgement (ACK/NAK) information for the data for each of the one or more serving cells configured for the UE;
- and
- transmitting, by the UE, the ACK/NAK information for each of the one or more serving cells configured for the UE,
- wherein the ACK/NAK information for each of the one or more serving cells configured for the UE consists of a number of bits, the number of bits being determined based on the transmission mode supported by the serving cell.
