Method and system for signalling resource allocation information in an asymmetric multicarrier communication network

An apparatus for receiving resource allocation information in an multicarrier communication system, the apparatus comprising:

• a processor;
• and
• a transceiver,
• wherein the transceiver is configured to receive resource allocation information in a control region included in a subframe on a primary downlink carrier, wherein the resource allocation information includes information indicating a start time for a downlink allocation interval for a secondary downlink carrier and information indicating a start time for an uplink allocation interval for a secondary uplink carrier,
• wherein the processor is configured to identify resources allocated in the downlink allocation interval for the secondary downlink carrier and the uplink allocation interval for the secondary uplink carrier based on the resource allocation information, wherein the downlink allocation interval is included in a part of a first subframe and a part of a second subframe on the secondary downlink carrier and starts at a first predefined offset after a start time of the subframe on the primary downlink carrier, wherein the uplink allocation interval is included in a part of a third subframe and a part of a fourth subframe on the secondary uplink carrier and starts at a second predefined offset after the start time of the subframe on the primary downlink carrier, wherein a duration of the downlink allocation interval is equal to a duration of one subframe, and wherein a duration of the uplink allocation interval is equal to the duration of one subframe, and
• wherein each of frequencies of the secondary downlink carrier and the secondary uplink carrier is higher than a frequency of the primary downlink carrier, and
• wherein transmission time intervals (TTIs) for both the secondary uplink carrier and the secondary downlink carrier are smaller than TTIs for the primary downlink carrier.
