The present invention provides a base station (100) for channel reciprocity calibration. The base station (100) is configured to transmit, in a resource element set, at least one reference signal (101) from at least one antenna (102) to at least one other antenna (102) of the base station (100). Further, it is configured to estimate a calibration parameter (103) for at least a channel (104) between said antennas (102) based on the at least one transmitted reference signal (101). The at least one reference signal (101) has the same format as reference (signals 201) used by User Equipment (200) served by the base station (100).
