Mobile communication system and resource allocation control method used therefor

摘要

A mobile communication system is provided which is capable of improving efficiency of use of allocated codes and allocated power of an HS-PDSCH to improve a throughput of the HS-PDSCH. A resource allocation update unit is connected to an RNC functional unit and a base station functional unit, performs allocation control of resources such as the number of codes and power, which are allocated or notified from the RNC functional unit to the base station functional unit, and stores allocation information of the resources in a resource allocation information storage unit. A resource use information detection unit detects a state of use of resources on the basis of a state of use of resources from the base station functional unit and a timing information from a timer, and informs a resource allocation judgment unit of the information on a state of use of resources. The resource allocation judgment unit judges whether or not allocation of resources has been updated on the basis of the information on a state of use of resources.
