Claim:
1. A communication method performed by a user equipment, the communication method comprising: determining a selected Channel Quality Indicator for (CQI table, from a legacy CQI parameter table and an aggressive CQI parameter table, based on a received indication, the aggressive CQI parameter table including combinations of higher modulation scheme and higher coding rate than the legacy CQI parameter table; determining a selected Modulation and Coding Scheme (MCS) table, from a legacy MCS parameter table and an aggressive MCS parameter table, to be used with the selected CQI table as a set, the aggressive MCS parameter table including combinations of higher modulation order and higher coding rate than the legacy MCS parameter table; and controlling communication based on one of the combinations of modulation scheme and coding rate corresponding to a CQI index in the selected CQI table and based on one of the combinations of modulation order and coding rate corresponding to a MCS index in the selected MCS table; wherein, the set of the selected CQI table and the selected MCS table is one of sets including a first set of the aggressive CQI parameter table and the legacy MCS parameter table and a second set of the legacy CQI parameter table and the aggressive MCS parameter table, and a number of bits that indicate the CQI index in the aggressive CQI parameter table equals a number of bits that indicate the CQI index in the legacy CQI parameter table, and a number of bits that indicate the MCS index in the aggressive MCS parameter table equals a number of bits that indicate the MCS index in the legacy MCS parameter table.
