1. A packet scheduling method in a radio communication apparatus having array antennas and transmitting packets to a plurality of mobile apparatuses using a plurality of fixed beams created by the array antennas, the method comprising:

  • a first step of selecting, based on inter-beam interference quantities each estimated in advance and stored for each of combinations of at least a part of the plurality of fixed beams, one of the fixed beams for communication with each of said mobile apparatuses residing in the coverage of the radio communication apparatus, and associating the selected fixed beam with the mobile apparatus;

    a second step of assessing states of channels toward the mobile apparatuses;

    a third step of selecting a combination of fixed beams to be output, based on the inter-beam interference quantities for combinations of fixed beams, associations between the mobile apparatuses and the fixed beams associated in said first step, and the states of the channels assessed in said second step; and

    a fourth step of generating by said array antennas the fixed beams in the combination selected in said third step and transmitting packets to the mobile apparatuses corresponding to the fixed beams in the selected combination.
