Abstract:
1. A method for use in a user equipment of a communications system, for transmitting information relating to channel quality Index (CQI) and precoding matrix index (PMI) multiplexed with uplink shared channel (UL-SCH) data information on a physical uplink shared channel (PUSCH), the method comprising: applying a method for channel coding CQI/PMI information, wherein a turbo coding method is applied when a size of the CQI/PMI information is above a first threshold value; setting based on the method applied for the channel coding, an offset value indicative of a difference in code rate between a code rate of the CQI/PMI information and an assigned code rate of the UL-SCH data information on the PUSCH; determining based on the offset value, the number of coded bits to be used for transmission of the CQI/PMI information; and transmitting the CQI/PMI information to a radio access network node on resources assigned based on the determined number of coded bits, wherein the offset value corresponds to a gain factor value determining a gain of the applied channel coding method over a default channel coding method; and wherein the applying, setting, determining and transmitting are performed by the user equipment.
