The present disclosure relates to a method for transporting and distributing data (2) between a baseband, BB, unit (3) and two or more radio units (4) comprised in a communications network (1) arranged to cover a service area (6). The method comprises defining (S1) a logical grid of beams matrix, GoB, (5) associated with a carrier frequency band (B0, B1, B2, B3, B4, B5, B6, B7) of the communications network (1), wherein the GoB (5) comprises a set (S) of beam indices (BI), and partitioning (S2) the set (S) of beam indices into disjoint subsets (DS1, DS2, DS3, DS4) of at least one beam index (BI) each. The method further comprises mapping (S3) each of the two or more radio units (4) to one disjoint subset (DS1, DS2, DS3, DS4) such that each disjoint subset (DS1, DS2, DS3, DS4) is associated with a single radio unit (4), and transporting (S5) the data (2) between the BB unit (3) and the two or more radio units (4) and distributing the transported data (2) between the radio units (4) based on the disjoint subsets (DS1, DS2, DS3, DS4) of beam indices (BI).
