Base station apparatus and communication control method

Abstract

A disclosed base station apparatus includes a resource allocation unit allocating radio resources using a first resource allocation method for dynamically allocating the radio resources and a second resource allocation method for allocating the radio resources at a constant period, wherein when a size of data to be transmitted is equal to or greater than a first threshold value, the resource allocation unit allocates the radio resources using the first resource allocation method, otherwise, the resource allocation unit allocates the radio resources using the second resource allocation method, and when the size of the data to be transmitted is equal to or greater than a second threshold value, the resource allocation unit allocates radio resources reserved as radio resources to be allocated using the second resource allocation method as radio resources to be allocated using the first resource allocation method.

         5 . A communication control method used in a base station apparatus capable of communicating with a user equipment terminal using a downlink shared channel, the method comprising:
 a selection step of selecting a user equipment terminal to which a shared channel is to be allocated from among user equipment terminals other than:   a user equipment terminal in which a time frame to transmit the shared channel or a time frame to receive acknowledgement information with respect to the shared channel overlaps with a time interval to measure cells operating at a different frequency,   a user equipment terminal in sleep mode of discontinuous reception mode,   a user equipment terminal which is out of synchronization,   a user equipment terminal that has not received radio quality information, and   a user equipment terminal having no data to be transmitted; and   a transmission step of transmitting the shared channel to the user equipment terminal selected in the selection step.
