Claim of US Patent No. 9,137,003

1. A transmission method with Time Division Duplex (TDD) multi-carrier aggregation, comprising:
performing uplink and downlink configurations for each of a plurality of component carriers aggregated in a cell while ensuring
coexistence of at least one identical uplink sub-frame and at least one identical downlink sub-frame between at least two
of the component carriers and compliance of the configuration of at least one of the component carriers with an uplink and
downlink configuration of R8; and

transmitting the uplink and downlink configuration of any one of the component carriers and those of other component carriers
aggregated with the any one of the component carriers to an LTE-A UE accessing a corresponding component carrier, wherein
the LTE-A UE is scheduled over sub-frames that are all in the uplink or downlink in a plurality of aggregated component carriers
when the LTE-A UE is to receive or transmit data simultaneously over a plurality of carriers.
