Method and apparatus for receiving CQI information and method and apparatus for transmitting CQI information

A method for transmitting Channel Quality Indication (CQI) information, comprising:

• receiving, at a terminal, a higher layer configuration signaling message from a base station;
• determining, by the terminal, CQI information based on one or more CQI tables according to the higher layer configuration signaling message;
• and
• transmitting, by the terminal, the CQI information to the base station,
• wherein the one or more CQI tables comprise a first CQI table and a second CQI table, the second CQI table including a combination of Quadrature Phase Shift Keying (QPSK) and code rate r, r being a real number smaller than 78/1024;
• wherein the second CQI table comprises L1+L2 combinations of modulation scheme and code rate, each combination represented by x bits, L1 and L2 each being an integer larger than or equal to 0, wherein L1+L2≤15, and x≤4;
• and
• wherein L1 combinations of modulation scheme and code rate in the first CQI table are used as the last L1 combinations of modulation scheme and code rate in the second CQI table.
