A method of arranging, in a mobile communication network, transmission of data ( S* INFO i,n,S* CTRL n) between user equipments ( UE i) and at least one base station comprising a central unit and at least one remote unit ( RU j) associated therewith, wherein said data ( S* INFO i,n,S* CTRL n) comprise information data ( S* INFO i, n) and control data ( S* CTRL n) from the central unit to the at least one remote unit ( RU j), or from the at least one remote unit ( RU j) to the central unit, the method comprising: allocating, among a plurality of available radio resources, radio resources for said data ( S* INFO i,n,S* CTRL n) to/from the at least one remote unit ( RU j) thereby obtaining allocated radio resources (P PRB p) and non-allocated radio resources for said data ( S* INFO i,n,S* CTRL n) to/from the at least one remote unit ( RU j), grouping the allocated radio resources (P PRB p) into at least one allocated radio resources group ( AG g,n) each one comprising at least one radio resource (P PRB p) allocated for data ( S* INFO i,n,S* CTRL n) to/from a respective remote unit ( RU j), the non-allocated radio resources being not included in said respective at least one allocated radio resource group, including in each allocated radio resources group ( AG g,n) association data ( A SS D) indicative of an association of the at least one allocated radio resource (P PRB p) of that allocated radio resources group ( AG g,n) with the respective remote unit ( RU j), including in each allocated radio resources group ( AG g,n) allocation data ( A LL D) indicative of the allocated radio resources ( P PRB p), among said at least one allocated radio resource ( P PRB p), that have been allocated at least for the information data ( S* INFO i,n), and transmitting said at least one allocated radio resources group ( AG g,n) in the frequency-domain between the central unit and the respective at least one remote unit ( RU j), the non-allocated radio resources being not transmitted thereto. allocating, among a plurality of available radio resources, radio resources for said data ( S* INFO i,n,S* CTRL n) to/from the at least one remote unit ( RU j) thereby obtaining allocated radio resources (P PRB p) and non-allocated radio resources for said data ( S* INFO i,n,S* CTRL n) to/from the at least one remote unit ( RU j), grouping the allocated radio resources (P PRB p) into at least one allocated radio resources group ( AG g,n) each one comprising at least one radio resource (P PRB p) allocated for data ( S* INFO i,n,S* CTRL n) to/from a respective remote unit ( RU j), the non-allocated radio resources being not included in said respective at least one allocated radio resource group, including in each allocated radio resources group ( AG g,n) association data ( A SS D) indicative of an association of the at least one allocated radio resource (P PRB p) of that allocated radio resources group ( AG g,n) with the respective remote unit ( RU j), including in each allocated radio resources group ( AG g,n) allocation data ( A LL D) indicative of the allocated radio resources ( P PRB p), among said at least one allocated radio resource ( P PRB p), that have been allocated at least for the information data ( S* INFO i,n), and transmitting said at least one allocated radio resources group ( AG g,n) in the frequency-domain between the central unit and the respective at least one remote unit ( RU j), the non-allocated radio resources being not transmitted thereto.
