Base station system and radio apparatus

A radio apparatus compatible with a link structure in which a plurality of the radio apparatuses are multistage-connected to each other and are configured to communicate with a radio equipment controller, the radio apparatus comprising:

• a memory;
• and
• control circuitry coupled to the memory,
• wherein a downlink transmission frame and an uplink transmission frame between the radio equipment controller and the plurality of the radio apparatuses include a plurality of blocks, in each of which a data signal is stored,
• wherein, among the plurality of blocks, one or several blocks are allocated to a shared area for a data signal that is shared among two or more of the radio apparatuses, and other blocks are allocated to an individual area a data signal that is not shared among two or more of the radio apparatuses,
• wherein the control circuitry is configured to
• execute a transferring process that includes transferring a measurement value relating to a traffic situation of an own radio apparatus, the measurement value being stored in at least one of the downlink transmission frame that is transferred from a front stage radio apparatus to a rear stage radio apparatus and the uplink transmission frame that is transferred from the rear stage radio apparatus to the front stage radio apparatus in the link structure, the front stage radio appratus being one of the radio apparatuses and being located at start of the link structure, the rear stage radio apparatus being one of the radio apparatuses and being located at end of the link structure,
• execute a collecting process that includes collecting a measurement value relating to a traffic situation of each of other radio apparatuses using at least one of the uplink transmission frame and the downlink transmission frame, and
• execute a selecting process that includes selecting whether the block that is used for a radio area which is provided by the own radio equipment is set to be a block that is allocated to the shared area, or a block that is allocated to the individual area, based on the collected measurement value relating to the traffic situation of each of the other radio apparatuses, and the measurement value relating to the traffic situation of the own radio apparatus.
