Abstract
A radio base station includes: a radio communicator configured to perform radio communication; and a first controller that includes a first scheduler configured to perform a first scheduling that is at least a first part of a scheduling for the radio communication; and a second controller that is coupled to the first controller via a network, wherein the second controller comprises a second scheduler configured to perform a second scheduling that is at least a second part of the scheduling for the radio communication.
Claims27
A radio base station comprising:
- at least one first device that forms a cell and performs radio communication with a wireless terminal, the at least one first device including a first controller that comprises a first processor, the first processor configured to execute a first scheduling process that includes at least a first part of a scheduling process for the radio communication, wherein the number of cells formed corresponds to a number of the at least one first device;
- and
- a second device including a second controller that is coupled to the first controller via a network, wherein the second controller is capable of controlling at least a part of the radio communication with the wireless terminal, the second controller comprising a second processor, the second processor configured to execute a second scheduling process that includes at least a second part of the scheduling process for the radio communication, the second part of the scheduling process including higher layer functions not included in the at least the first part of a scheduling process, and wherein the radio base station adaptively adjusts the scheduling process performed by the second controller and the first controller for the radio communication according to at least one of a plurality of radio communication parameters.
A central apparatus of a base station comprising:
- a second processor configured to be coupled to at least one distributed apparatus of the base station via a network, the at least one distributed apparatus forms a cell and includes a radio communicator and a first processor, the radio communicator configured to perform a radio communication, wherein the second processor is capable of controlling at least a part of the radio communication, and the first processor configured to execute a first scheduling process that includes at least a first part of a scheduling process for the radio communication, wherein the number of cells formed corresponds to a number of the at least one distributed apparatus, wherein the second processor is configured to execute a second scheduling process that includes at least a second part of the scheduling process for the radio communication, the second part of the scheduling process including higher layer functions not included in the at least the first part of a scheduling process, and wherein the scheduling process performed by the second processor and the first processor for the radio communication is adaptively adjusted according to at least one of a plurality of radio communication parameters.
A distributed apparatus of a base station comprising:
- a radio communicator that forms a cell and is configured to perform a radio communication;
- and
- a first processor coupled to a central apparatus of the base station via a network, the first processor configured to control a first part of the radio communication, the central apparatus including a second processor, the second processor configured to execute a second scheduling process that includes at least a second part of a scheduling process for the radio communication and capable of controlling at least a part of the radio communication, wherein the first processor is configured to execute a first scheduling process that includes at least a first part of the scheduling process for the radio communication, the second part of the scheduling process including higher layer functions not included in the at least the first part of a scheduling process, and wherein the scheduling process performed by the second processor and the first processor for the radio communication is adaptively adjusted according to at least one of a plurality of radio communication parameters.
A method of scheduling radio communication comprising:
