An information configuration method, an information configuration apparatus and a communication system, wherein the method includes: the base station configures a user equipment (UE) with a mapping relation between configuration information of one or more sets of reference signals and indication information indicating the configuration information according to an antenna port formed by virtualizing a two-dimensional planar antenna array. By configuring the UE with the configuration information by the base station according to the antenna port formed by virtualizing the two-dimensional planar antenna array, the configuration information is adaptive to the two-dimensional planar antenna array, such that the user end accurately acquires the configuration information of the array.
