Disclosed are a method and apparatus for enhancing a multi-carrier cell, and a computer storage medium. The method includes: when broadcasting a common carrier list of a multi-carrier cell, simultaneously broadcasting, by a base station, at least one piece of following configuration information at the same time: a first common carrier list of a first-type user equipment (UE), or a second common carrier list of the first-type UE, where the first-type UE is a UE supporting a multi-carrier cell enhancement function; and if the broadcast configuration information includes the second common carrier list of the UE, simultaneously broadcasting indication information about whether the first-type UE can use a carrier in a common carrier list of a second-type UE, or a weight value of each carrier configured for the first-type UE is broadcast at the same time, where the second-type UE is a UE not supporting the multi-carrier cell enhancement function.
