Claim 6:
7. A method for receiving acknowledgement/negative acknowledgement (A/N) by a transmission/reception facility that communicates with user equipment configured with at least two serving cells comprising a primary cell (PCell) and a secondary cell (SCell), the PCell and the SCell having different Time Division Duplex (TDD) Uplink-Downlink (UL-DL) configurations, the method comprising:
determining a reference TDD configuration for the SCell, the reference TDD configuration for the SCell being determined based on a PCell TDD UL-DL configuration and SCell TDD UL-DL configuration pair in Table 7-1 below:, TABLE 7-1

Reference TDD configuration for SCell

receiving a first acknowledgment/negative acknowledgment (A/N) from the user equipment in an uplink subframe ‘n’, the first A/N transmitted in the uplink subframe ‘n’ being responsive a PDSCH transmission in the subframe ‘n−ki’,
wherein n, k and i are integers, ki∈K, a downlink set K for each reference TDD configuration being defined in Table 7-2, 0≤i≤M−1, M is the number of elements in the downlink association set K., TABLE 7-2

Downlink association set index K: {k0, k1 . . . kM − 1} for TDD
