Abstract:
A base station, comprising a first antenna for transmitting a first pilot signal; a second antenna for transmitting a second a pilot signal; a third antenna for transmitting a third pilot signal; and a fourth antenna for transmitting a fourth pilot signal. The base station is configured to transmit pilot signal power information for indicating power values to a user equipment, UE, receiving the pilot signal power information. The pilot signal power information comprises: a first power value corresponding to the first pilot signal, a second power value corresponding to the second pilot signal, a third power value corresponding to the third pilot signal, and a fourth power value providing information regarding at least two demodulation pilot signals.
