First Claim
1. A radio communication system, characterized in thata transmitter comprising M antennas (M is an integer equal to or more than two) to transmit signals to a receiver, comprising:
- transmission signal control means for receiving as inputs thereto profile information items of N users (N is an integer equal to or more than two);
determining, by use of the profile information items, a radio resource amount to be distributed to each of the N users and assignment thereof as well as application or non-application of beam forming; and
creating and outputting radio resource control signals indicating the radio resource amount to be distributed and the assignment thereof and transmission mode control signals indicating a result of the application or non-application; and
transmission signal creating means for receiving as inputs thereto transmission data items of the N users, the radio resource control signals, and the transmission mode control signals;
allocating radio resources to N1 users (N1 is an integer equal to or more than one and equal to less than N) to which radio resources are allocated on the basis of the radio resource control signals, creating the transmission signals using the transmission data items by applying the beam forming for N2 users (N2 is an integer equal to or more than zero and equal to less than N1) for whom the transmission mode control signals indicate the application, creating the transmission signals using the transmission data items without applying the beam forming for N3 users (N3 is an integer equal to or more than zero and equal to less than N1 and N2+N3=N1) for whom the transmission mode control signals indicate the non-application, and outputting the transmission signals thus created.

Abstract
Although the beam forming is quite a good scheme, if there exist particularly a plurality of users, the characteristic deterioration occurs in an associated communication line due to the tight radio resource on the reverse line and delay in the transmission time caused by the feedback of information exceeding the required information. The transmitter 1 in a radio communication system receives signals by the antennas 13-1 to 13-M and the duplexers 14-1 to 14-M, extracts user'"'"'s profile information by the transmission signal controller 12, determines in a unified manner a radio resource amount and its assignment as well as the application or non-application of the beam forming, generates by the transmission signal generator 11 transmission signals using user'"'"'s transmission data according to the resource distribution and the application or non-application of the beam forming thus determined, and transmits the signals by use of the duplexers 14-1 to 14-M and the antennas 13-1 to 13-M.
