COMMUNICATION DEVICE AND METHOD THEREOF

摘要

Method for a communication device is disclosed. The method comprises being configured with at least one uplink carrier and at least one downlink carrier according to a carrier aggregation configuration, receiving, by the communication device, at least one control signal at at least one downlink control channelon the at least one downlink carrier, determining, by the communication device, at least one control format of the at least one control signal for at least one of at least one uplink and at least one downlink transmission or for at least one control signaling carried on the same or different at least one uplink carrier or the at least one downlink carrier, and performing, by the communication device, at least one of the at least one uplink and the at least one downlink transmission or at least one control signalingon the same or different at least one uplink carrier or the at least one downlink carrier according to the at least one control format of the at least one control signal, wherein the at least one of at least one uplink and the at least one downlink transmission or the at least one control signaling use a same or different transmission modes on the same or different at least one uplink carrier or the at least one downlink carrier.
