9. A transmission power control method in a plurality of radio communication apparatuses that perform asymmetrical communication, said method comprising:
in one of the plurality of communication apparatuses;
measuring individual desired signal reception powers of a plurality of slots;
calculating an average value of the individual desired signal reception powers of the plurality of slots;
measuring individual interference signal reception powers of the plurality of slots;
generating individual transmission power control information corresponding respectively to the plurality of slots, for each slot the individual transmission power control information being generated based on the average value of the individual desired signal reception powers and one of the individual interference signal powers corresponding to said each slot; and
transmitting the individual transmission power control information corresponding respectively to the plurality of slots, in a single slot, and
in another one of the plurality of radio communication apparatuses:
isolating, from a received signal, the individual transmission power control information corresponding respectively to the plurality of slots; and
amplifying individual transmission powers of a plurality of transmitting slots based on the individual transmission power control information corresponding respectively to the plurality of slots.
