Mobile communication system, mobile communication method, and mobile station suitably used for the same
First Claim
1. A mobile communication system which transmits a data signal from a base station to a mobile station, whereinthe base station comprises a signal transmitter configured to transmit, to the mobile station, both the data signal, and at least one retransmission signal of the same data signal, in a different form from the same data signal, within a predetermined period set for transmission of at least one series of the data signal and the at least one retransmission signal;
- the mobile station comprises;
a receiving processor configured to carry out a receiving process on the data signal or the at least one retransmission signal within the predetermined period;
a communication quality detector configured to detect a communication quality of the data signal or the at least one retransmission signal; and
a reception processing method decider configured to decide a reception processing method for the data signal or the at least one retransmission signal in the predetermined period, based on the detected communication quality.

Abstract
The object of the present invention is provide a mobile communication system which can reduce power consumption of a mobile station without increasing the number of times the data signals which are to be received by the mobile station are retransmitted. The base station 10 comprises a signal transmitter 11 configured to transmit the data signal a to the mobile station 30 within a predetermined period, and transmit each of retransmission signals a1 to a3 of the data signal a, in a form different from that of the data signal a, from the base station 10 to the mobile station 30 within the predetermined period A. The mobile station 30 comprises a receiving processor 31 configured to carry out receiving processing of the data signal a or the retransmission signal a1 within the predetermined period A; a communication quality detector 32 configured to detect a communication quality of the data signal a or the retransmission signal a1; and a reception processing method decider 33 configured to decide a reception processing method for the data signal a or the retransmission signal a1 in the predetermined period A, in accordance with the communication quality detection result.
