Abstract

The embodiments of the invention relate to a transmitter method for multiple antenna systems. The transmitter method contains the step of operating at least one antenna array in a first operation mode by transmitting first transmit signals (TS1-1, TS1-a, TS1-A) from a first number of antenna elements (AEG1) with a first transmit power and the step of operating the at least one antenna array in at least one second operation mode by transmitting at least second transmit signals (TS2-1, TS2-b, TS2-B, TS3-1, TS3-C, TS3-C) from at least one second number of antenna elements (AEG2, AEG3) smaller than the first number of antenna elements with at least one second transmit power larger than the first transmit power. The embodiments of the invention further relate to a transmitter apparatus for multiple antenna systems. The transmitter apparatus contains means for operating at least one antenna array in a first operation mode by transmitting first transmit signals (TS1-1, TS1-a, TS1-A) from a first number of antenna elements (SUB-G1) with a first transmit power and for operating the at least one antenna array in at least one second operation mode by transmitting second transmit signals (TS2-…
