Abstract: A work support apparatus, which assigns an operator to an operation performed in a workplace, includes a communication device used for the operation in the workplace, and holds information on a relationship between a process, an operation, and each of divided areas of the workplace and the communication device used for the operation, information on a predicted communication throughput by the communication device in each of the divided areas, and information on an operator-requested communication throughput for a combination of the operation and an operator. For each operation corresponding to the process, the apparatus determines assignment of an operator to the operation, referring to the predicted communication throughput by the communication device and the operator-requested communication throughput, and outputs a result of the operator assignment.

Abstract: The present invention provides a method of controlling the selection of a cell in a radio communication system for increasing the capacity of the system by effectively utilizing a small cell base station and a base station apparatus for realizing it. At least one base station of a macrocell base station and a small cell base station is provided with plural antennas, and the base station selects a cell and adjusts a criterion for reselection by generating processing gain using the plural antennas by signal processing and performing a cell selection bias correcting process using the processing gain using the plural antennas.

Abstract: Radio communication system and radio station which enable efficient use of radio resources while coping with a sudden change in radio communication quality are to be provided. Radio communication system includes plural radio stations. At least one of the plural radio stations allocates a part of an allocatable communication resource as one or more individual resources in which a source radio station and a destination radio station are individually set, and allocates another part of the allocatable communication resource as one or more shared resources which are used in common by plural source radio stations or plural destination radio stations. Each of the radio stations encodes a transmission signal using a systematic code, sends the transmission signal before being encoded, using the individual resource allocated to each of the radio stations, and sends a parity portion of the encoded transmission signal, using the shared resource allocated.
