A method for allocating resources to multi-carrier response information feedback, comprising: allocating, by a base station, Physical Uplink Control Channel, PUCCH, resources to response information feedback of various secondary component carriers in carrier aggregation from a user equipment, wherein, when a Transmit Power Control, TPC, command in Downlink Control Information, DCI, of said various secondary component carriers in carrier aggregation is different, Physical Uplink Control Channel, PUCCH, resources allocated to said response information feedback of the various secondary component carriers are higher layer configuration PUCCH resources designated by said TPC command in the DCI which triggers data services in the various secondary component carriers; when the TPC command in the DCI of said various secondary component carriers is the same, a PUCCH resource allocated to said response information feedback corresponding to a first secondary component carrier of said various secondary component carriers, referred to as n PUCCH,1 1, is a higher layer configuration PUCCH resource designated by said TPC command in the DCI which triggers a data service in the first secondary component carrier; characterized in that: when the number of said various secondary component carriers is 2, a PUCCH resource corresponding to a second secondary component carrier of said various secondary component carriers is n PUCCH,2 1 = ⌈ n PUCCH,1 1 + 1 * c ⌉; when the number of said various secondary component carriers is 3, a PUCCH resource corresponding to a third secondary component carrier of said various secondary component carriers is n PUCCH,3 1 = ⌈ n PUCCH,1 1 + 2 * c ⌉; and when the number of said various secondary component carriers is 4, a PUCCH resource corresponding to a fourth secondary component carrier of said various secondary component carriers is n PUCCH,4 1 = ⌈ n PUCCH,1 1 + 3 * c ⌉, wherein, c is a resource location adjustment factor, which is a positive integer, and ┌ ┐ represents rounding up to an integer. allocating, by a base station, Physical Uplink Control Channel, PUCCH, resources to response information feedback of various secondary component carriers in carrier aggregation from a user equipment, wherein, when a Transmit Power Control, TPC, command in Downlink Control Information, DCI, of said various secondary component carriers in carrier aggregation is different, Physical Uplink Control Channel, PUCCH, resources allocated to said response information feedback of the various secondary component carriers are higher layer configuration PUCCH resources designated by said TPC command in the DCI which triggers data services in the various secondary component carriers; when the TPC command in the DCI of said various secondary component carriers is the same, a PUCCH resource allocated to said response information feedback corresponding to a first secondary component carrier of said various secondary component carriers, referred to as n PUCCH,1 1, is a higher layer configuration PUCCH resource designated by said TPC command in the DCI which triggers a data service in the first secondary component carrier; characterized in that: when the number of said various secondary component carriers is 2, a PUCCH resource corresponding to a second secondary component carrier of said various secondary component carriers is n PUCCH,2 1 = ⌈ n PUCCH,1 1 + 1 * c ⌉; when the number of said various secondary component carriers is 3, a PUCCH resource corresponding to a third secondary component carrier of said various secondary component carriers is n PUCCH,3 1 = ⌈ n PUCCH,1 1 + 2 * c ⌉; and when the number of said various secondary component carriers is 4, a PUCCH resource corresponding to a fourth secondary component carrier of said various secondary component carriers is n PUCCH,4 1 = ⌈ n PUCCH,1 1 + 3 * c ⌉, wherein, c is a resource location adjustment factor, which is a positive integer, and ┌ ┐ represents rounding up to an integer. when the number of said various secondary component carriers is 2, a PUCCH resource corresponding to a second secondary component carrier of said various secondary component carriers is n PUCCH,2 1 = ⌈ n PUCCH,1 1 + 1 * c ⌉; when the number of said various secondary component carriers is 3, a PUCCH resource corresponding to a third secondary component carrier of said various secondary component carriers is n PUCCH,3 1 = ⌈ n PUCCH,1 1 + 2 * c ⌉; and when the number of said various secondary component carriers is 4, a PUCCH resource corresponding to a fourth secondary component carrier of said various secondary component carriers is n PUCCH,4 1 = ⌈ n PUCCH,1 1 + 3 * c ⌉, wherein, c is a resource location adjustment factor, which is a positive integer, and ┌ ┐ represents rounding up to an integer.
