Abstract
A communication terminal device of the present invention can prevent assignment of unnecessary wireless resources and can efficiently assign the wireless resources in a situation in which there is data that cannot be transmitted immediately. In the device, a MAC control element generation unit (115) generates a BSR MAC control element for reporting to a base station a transmittable data volume. The memory usage management unit (106), if a notification is received that resources have been exhausted from the memory usage management unit (111), or if the stored data volume of a pre-encryption data buffer (102) or a post-encryption data buffer (104) exceeds a threshold, performs a transmittable data volume notification, in which the stored data volumes of the pre-encryption data buffer (102) and the post-encryption data buffer (104) are set to “0,” to the BSR MAC control element generation unit (115).
