Abstract: The present disclosure provides a method and an apparatus for receiving Channel Quality Indication (CQI) information, as well as a method and an apparatus for transmitting CQI information. The method for receiving CQI information includes: transmitting a higher layer configuration signaling message to a terminal; and receiving CQI information from the terminal. The CQI information is determined based on a CQI table obtained based on the higher layer configuration signaling message. With the above solutions, higher data transmission reliability and lower data transmission rate required for MTC terminals with coverage enhancement and 5G terminals can be achieved.

Abstract: The present invention provides a data transmission method and apparatus. The method includes: transmitting physical downlink channel data according to a first-type reference signal (RS) or a second-type RS or a third-type RS. The method of the present invention ensures a balance between data transmission performance and RS overheads for different NarrowBand-Internet Of Things (NB-IOT) physical downlink channel data, thereby resolving the problem in the related art of not knowing which RS is to be used to transmit NB-IOT physical channel data.
