A base station employs adaptive modulation to connect to a wireless terminal. The base station has first processing means and second processing means. The first processing means decides the target value of the total number of bits of traffic to said wireless terminal, the target value being mapped to radio resources. The second processing means decides the modulation scheme for said wireless terminal according to the adaptive modulation such that the total number of bits to be transmitted is restricted based on said target value, blank resources of said radio resources are decreased, and the transmission power density becomes constant and small. |
