Abstract:
The embodiments herein relate to a method in a base station (301) for determining adjustment of common pilot power in a four-way transmit antenna, 4Tx, communications system (300). The base station (301) comprises a first transmit antenna (1201), a second transmit antenna (1202), a third transmit antenna (1203) and a fourth transmit antenna (1204). The base station (301) identifies a set of scheduled user equipments (310) in the communications system (300). The base station (301) determines that the common pilot power should be adjusted based on a criterion associated with the set of scheduled user equipments (310).
