METHODS AND NODES FOR ADAPTING CODING AND BETA OFFSET OF CSI PAYLOAD AS A FUNCTION OF THE LENGTH OF THE CSI PAYLOAD

摘要

The present invention relates to a method for use in a user equipment of a communications system, for transmitting information relating to CQI and PMI, multiplexed with UL-SCH data information on a PUSCH. The method comprises applying (600) a method for channel coding the CQI/PMI information, wherein a turbo coding method is applied when the size of the CQI/PMI information is above a first threshold value. The method further comprises setting (610), based on the method applied for the channel coding, an offset value indicative of the difference in code rate between the code rate of the CQI/PMI information and the assigned code rate of the UL-SCH data information on the PUSCH. The method also comprises determining (620), based on the offset value, the number of coded bits to be used for transmission of the CQI/PMI information, and transmitting (630) the CQI/PMI information to a radio access network node on resources assigned based on the determined number of coded bits.
