Summary:An uplink resource allocation method and apparatus determine Modulation and Coding Scheme (MCS) level dynamically based on an MCS index table in a wireless communication system. The dynamic uplink resource allocation method of the present disclosure includes normalizing an uplink transmission power; selecting one of a current Modulation and Coding Scheme (MCS) index table and at least one candidate MCS index table; and determining a MCS level using the normalized transmission power and the selected MCS index table. The dynamic uplink resource allocation method and apparatus of the present disclosure is capable of determining the MCS level depending on the MCS index table selected optimally in consideration of the number of users and uplink resource utilization ratio of the base station that are varying as time goes, thereby enhancing single user throughput and sector throughput and thus service quality.
