Abstract:
Selection of a suitable MCS improves throughput without increasing the number of pieces of control information. With RRC signaling, information on PDCCH and a CQI table that is referred to are associated with each other, and the CQI table that is referred to is determined based on information relating to the PDCCH. Thus, the CQI table that is referred to is selected at high speed. Furthermore, information relating to control information is control information that is included in the PDCCH or an ePDCCH. Furthermore, the information relating to the control information is a type of search space of the PDCCH or the ePDCCH.
