CQI adjustment for arbitrary transport format selection algorithms

摘要

Network node (100), mobile terminal (200), method and computer program wherein a network node (100) or a mobile terminal (200) comprise a transceiver (110, 210) which is adapted for transmitting data frames comprising data transport blocks and redundancy information, further comprising a processing unit (120, 240) receiving at least one parameter value indicative of the quality of a radio channel and at least one message indicative of an actual block error rate for the transmitted data frame, wherein the processing unit (120, 240) determines an expected block error probability for each transmitted data frame and adjusts the at least one received parameter value based on the difference between an at least one previously calculated block error probability and the actual block error rate.

1. A network node for communication in a wireless communication network, said network node comprising:
a processing unit configured to receive at least one parameter value indicative of the quality of a radio channel, adjust the at least one parameter value by a correction value, and select a data frame structure comprising transport blocks and redundancy information based on an achievable signal quality associated with the adjusted parameter value; and a transceiver configured to transmit the selected data frame structure; wherein said processing unit is further configured to receive a message indicative of an actual block error rate for the transmitted data frame structure, and to select the data frame structure based on determining an expected block error probability for each transmitted data frame, estimating a new Block Error Rate target using the expected block error probability, and adjusting the at least one received parameter value based on the difference between the new Block Error Rate target and the actual block error rate.
