Abstract:
A method of allocating transmission resources at a Media Access Control (MAC) entity of a node of a Universal Mobile Telecommunications System (UMTS), the method comprising for each frame of an output data flow:computing for each input flow to the MAC entity a fair share of the available output bandwidth of the MAC entity; selecting a Transport Format Combination (TFC) from a TFC Set (TFCS) on the basis of the bandwidth share computed for the input flows, where the TFC comprises a Transport Format allocated to each input flow; and for each input flow, if the allocated TF results in a data transmission rate which is less than a determined fair distribution, adding the difference of the resulting data rate and the determined fair distribution to a backlog counter for the input flow, wherein the value of said backlog counter is taken into account when selecting a TFC for the subsequent frame of the output data flow.
