System and method of processing antenna configuration information
A base station encodes antenna configuration information of a neighboring cell of a first cell, and sends encoded information relating to the antenna configuration information of the neighboring cell to a user equipment (UE). The UE is capable of communicating with the base station in the first cell. The UE receives the encoded information; decodes the antenna configuration information of the neighboring cell from the encoded information; and performs determination of predetermined time-frequency resource according to the antenna configuration information of the neighboring cell. The predetermined time-frequency resource is used by a base station of the neighboring cell for transmitting pilot measurement information.
