Abstract

Claims (449)

1. A method for transmitting an uplink signal by a wireless device configured with a primary cell having a first Time Division Duplex Uplink-Downlink (TDD UL-DL) configuration and a secondary cell having a second TDD UL-DL configuration different from the first TDD UL-DL configuration, the method comprising:

receiving, by the wireless device, one or more data within subframe #n−k′ (k′∈K′) on the secondary cell; and

transmitting, by the wireless device, acknowledgement information about the one or more data in subframe #n according to a reference TDD UL-DL configuration different from the second TDD UL-DL configuration,

wherein K′ consists of a subset of elements of K:{k 0 , k 1 , . . . , k M−1 } of the reference TDD UL-DL configuration as defined in Table 1 below such that subframe #n−k′ in the secondary cell is only a downlink subframe or a special subframe,

wherein TDD UL-DL configurations are defined according to table 2:
