The embodiments herein relate to a method in a centralized baseband unit (CBU) for generating a common UL-TPC stream in a network. The CBU is connected to a plurality of RRUs. Each RRU is connected to a UE via a respective RLS of a plurality of RLSs. Each respective RLS comprises at least one radio link. The CBU receives, from each RRU a stream of uplink power samples measured for each RRU on the at least one radio link comprised in each respective RLS between the UE and the plurality of RRUs. The CBU generates the common UL-TPC stream based on the received measurements of uplink power. The common UL-TPC stream is to be sent to each RRU for further transmission to the UE.
