Abstract

The embodiments of the invention relate to a method for operating a first base station (BS1) in a radio communication system (RAN). The method contains transmitting first reference signals via a first radiation beam (BM1-BS1) being directed towards a first direction and at least second reference signals via at least one second radiation beam (BM2-BS1, ..., BM5-BS1) being directed towards at least one second direction. The method further contains receiving for a handover of a mobile station (MS) from a second base station (BS2) being a serving base station of the mobile station (MS) to the first base station (BS1) an indication for a radiation beam being selected from a group of radiation beams comprising the first radiation beam (BM1-BS1) and the at least one second radiation beam (BM2-BS1, ..., BM5-BS1) for applying the selected radiation beam as an initial radiation beam at the first base station (BS1) for serving the mobile station (MS). The method even further contains scheduling radio resources for the initial radiation beam for serving the mobile station (MS) based on the indication. The embodiments further relate to a method for operating a second base station (BS2) in a radio communication system (RAN), to a first base station (BS1) for operation in a radio communication system (RAN) and to a second base station (BS2) for operation in a radio communication system (RAN).
