摘要： A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.

摘要： A base station of a mobile communication system includes a scheduler that generates uplink grant information indicating that uplink radio resources are allocated to less than or equal to a first multiplexing number of units of user equipment, a transmitter that transmits a control signal including the uplink grant information to the user equipment, and a receiver that receives an uplink signal which is transmitted by the user equipment. When a second multiplexing number being less than the first multiplexing number or more units of the user equipment exist which transmit periodically generated periodic data, and when the user equipment exists which transmits non-periodic data generated at non-periodic timing, the scheduler generates the uplink grant information indicating that the uplink radio resources are allocated to the second multiplexing number of the units of the user equipment that transmit periodic data and to the user equipment that transmits non-periodic data.
