1. An apparatus, comprising:
a processor configured to cause a user equipment (UE) to:
receive radio resource control (RRC) configuration information from a base station, the RRC configuration information including:
a channel quality indicator (CQI) table indication identifying a CQI table of a plurality of CQI tables; and
an MCS table indication identifying an MCS table, the identified MCS table comprising one of a first MCS table and a second MCS table, wherein the first MCS table identifies respective higher target code rates for respective MCS indexes than corresponding respective target code rates for the respective MCS indexes according to the second MCS table;
determine, based on a transport block error probability associated with the CQI table, a CQI index associated with the CQI table, the CQI index for MCS selection by the base station, wherein the transport block error probability is one of 0.1 or 0.00001 and is determined based on the CQI table indication;
transmit, to the base station, an indication of the CQI index; and
receive a downlink (DL) grant using the identified MCS table, wherein the second MCS table includes the following modulation order and target code rate for MCS index values of 0-3:
