Abstract
A base station (102), comprising a first antenna (111) for transmitting a first pilot signal; a second antenna (112) for transmitting a second a pilot signal; a third antenna (113) for transmitting a third pilot signal; and a fourth antenna (114) 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 (104), 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.
