TERMINAL DEVICE AND METHOD OF BUFFER SEPARATION Russian patent published in 2017 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: terminal stores in the retransmission buffer the DL data (downlink) transmitted by each of the plurality of component carriers, decodes the DL data, and transmits, using the first component carrier, a response signal for the first DL data received using the first component carrier, and a response signal for the second DL data received using the second component carrier. The buffer is divided into areas corresponding to the HARQ (hybrid automatic retransmission request) processes based on the value determined by the combination of the first configuration pattern specified on the first component carrier and the second configuration pattern specified on the second component carrier.

EFFECT: providing gain when encoding by hybrid automatic repeat request for the entire downlink of HARQ processes when the UL-DL configuration is different for multiple component carriers.
