1. A method of transmitting data packets in a wireless communication system using a multiple input multiple output (MIMO) scheme supporting multiple carriers, the method comprising:

  • receiving feedback information from at least one access terminal, wherein the feedback information comprises information of at least one combination of a carrier or a subcarrier, an antenna and a sector, and information indicating a best pilot type corresponding to each antenna of the at least one combination from among predefined pilot types,wherein the at least one combination has the best channel condition; and

    transmitting a transmit packet via at least one data channel based on the best pilot type corresponding to each antenna of the at least one combination having the best channel condition;

    wherein re-transmission of subsequent transmit packets are performed using an automatic request (ARQ) or an hybrid-ARQ (HARQ) scheme using the at least one combination which can be set to be different from the previous at least one combination used to transmit the previous transmit packet based on the received feedback information.
