Abstract:
1. A method of power control of a data channel between a Node B and a User Equipment, UE, in a cellular communication system in case of segmentation of a Radio Link Control, RLC, Protocol Data Unit, PDU, into m Media Access Control, MAC, segments, wherein a target Block Error Rate, BLER, for transmission of unsegmented RLC PDUs is set to p, said method comprising the steps of: determining a transmit power boost for transmission of the MAC segments, wherein the transmit power boost is equal to a first Carrier-to-Interference Ratio, CIR, minus a second CIR, wherein the first CIR is required for transmission of the MAC segments in order to reach a target BLER of p divided by m, and wherein the second CIR is required for transmission of the MAC segments in order to reach the target BLER p; and applying the determined transmit power boost for transmission of the MAC segments.
