More Information
Summary:A method performed by a system having a plurality of base station systems, each base station system comprising a baseband unit, BBU and a radio unit, RU interconnected via a fronthaul connection that is shared between the base station systems. Fronthaul capacity information on transmission capacity of the shared fronthaul connection and information on required capacity for transmission and/or reception of wireless signals by the RU of the respective base station system are obtained. Time unit transmission restrictions for the respective base station system is determined based on the fronthaul capacity information and on the information on required capacity, which time unit transmission restrictions results in fronthaul usage below the transmission capacity of the part of the fronthaul connection. Information on the determined time unit transmission restrictions is sent to the BBU of the respective base station system.
