The invention relates to Coordinated MultiPoint (COMP) operation in a cellular communication network. A supporting radio base station (RBS) (100) is configured to provide complementary IQ samples and transmit, via a network interface to a transport network, these IQ samples to a multicast group that includes a serving RBS (200) to enable the serving RBS to decode user data based on both complementary IQ samples and own IQ samples. The serving RBS (200) is thus configured to provide own IQ samples, and join the multicast group for receiving, via a network interface to a transport network, complementary IQ samples from the supporting RBS (100). |
