FIELD: wireless communication technology.
SUBSTANCE: invention relates to the field of wireless mobile communication technology. Apparatus for use in the UE includes one or more processing units for decoding a Radio Resource Control (RRC) message, indicating a presence of a secondary modulation table and a coding scheme (MCS), the secondary MCS table comprising an entry corresponding to a 256-quadrature amplitude modulation (QAM) scheme; decoding the downlink control information (DCI) in the physical control channel of the downlink (PDCCH), DCI has a DCI format; and selecting one of the MCS table by default and the secondary MCS table based on the availability of the secondary MCS table and the DCI format.
EFFECT: device is designed to increase the coverage area using the user device (UE) in the small cell deployment schemes, and to enable the use of higher order modulation schemes for data transmission on the downlink.
