Abstract

The present invention relates to a radio base station (RBS) (1). The RBS comprises a first radio unit (RU) (2) and a second RU (3). The RBS is configured such that said first and second RUs will use the same scrambling or cell identity code for communication with a wireless communication terminal (9) such that the wireless communication terminal will regard the first and second RUs as relating to the same cell of the RBS. The invention also relates to a communication system (13) comprising the RBS, as well as to a use of the RBS for performing an internal handover, after UL measurements, of the communication terminal from the first RU to the second RU, and a method of arranging the RBS.
