Base station, mobile station, communication system, and communication method

Abstract

A base station communicates with plural mobile stations using a common channel common to the mobile stations, and a predetermined number of a plurality of shared channels assigned to the mobile stations. The base station includes a scheduler that acquires, for each of the mobile stations, a transmitting power ratio being a ratio of a mobile station assigning power, which is a sum of transmitting powers of the shared channels assigned to the mobile station, and a transmitting power of the common channel. The scheduler determines the mobile station assigning power of the mobile station and then selects communication destination mobile stations, so that a sum of the mobile station assigning powers does not exceed a predetermined maximum assignable power.

1 . A base station that communicates with a plurality of mobile stations using a common channel and a plurality of shared channels, wherein the common channel is common to the mobile stations, and a predetermined number of the plurality of shared channels can be assigned to the respective mobile stations, the base station comprising:
 a scheduler that determines, for each communication destination mobile station, a mobile station assigning power, which is a sum of transmitting powers of shared channels assigned to each communication destination mobile station, by dividing an assignable power as a maximum power assignable to the shared channels by a number of shared channels assigned to each communication destination mobile station.   
   
   
       2 . A base station that communicates with a plurality of mobile stations using a common channel and a plurality of shared channels, wherein the common channel is common to the mobile stations and a predetermined number of the plurality of shared channels can be assigned to the respective mobile stations, the base station comprising:
 a scheduler that selects communications destination mobile stations so that a sum of transmitting powers assigned to the shared channels does not exceed a predetermined maximum assignable power.
