Distributed load balancing in a radio access network

摘要

Embodiments relate to a baseband processing apparatus (200) for processing baseband signals to or from at least one remote radio head (204), the at least one remote radio head (204) serving a radio cell of a cellular communication system, the baseband processing apparatus (200) comprising: an interface (208) to connect the baseband processing apparatus (200), as a first node (200-1) of a network (300), to a further baseband processing apparatus as a second node (200-2) of the network (300); a plurality of dedicated user data processors (210; 410; 420), wherein each is operable to process user specific data of first users being associated to the radio cell, the processing of the user specific data of the first users leading to a processing load of the first node (200-1); and a load balancer (212) operable to exchange load information with a load balancer of the second node (200-2) via the interface (208) and to distribute processing tasks between the plurality of dedicated user data processors (210; 410; 420) of the first node (200-1) and/or to distribute processing tasks between plurality of dedicated user data processors (210; 410; 420) of the first node (200-1) and the second node (200-2) in response to the exchanged load information in order to distribute processing load among different nodes of the network (300).
