Method of and Node B and user equipment for power control in case of segmentation

摘要

A method (200, 400) of and a Node B (102) and a User Equipment (UE) (106) for power control of a data channel (100, 112) between the Node B (102) and the UE (106) in a cellular communication system in case of segmentation of a Radio Link Control (RLC), Protocol Data Umt (PRC) into m Media Access Control (MAC) segments are provided The method (200, 400) comprises the steps of determining (202, 402) a transmit power boost for transmission of the MAC segments and applying (204, 404) the determined transmit power boost for transmission of the MAC segments A method (500) of and a Node B (102) for power control of an uplink data channel (112) in case of segmentation are also provided The method (500) comprises determining (504) a Signal-to-Interference Ratio (SIR) target boost and applying (506) the determined SIR target boost for power control.

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.
