Abstract
A communication terminal apparatus requests resource allocation to a communication control apparatus without allocating any dedicated resource for resource request. The communication terminal apparatus is applied to a wireless communication system in which the communication control apparatus allocates resources used when a communication terminal apparatus 200 performs wireless transmission to a communication control apparatus 100. The communication terminal apparatus includes: a determination unit 210 determining whether to make resource request to the communication control apparatus 100; and a signal control unit 211 which transmits a signal used to maintain time-frequency synchronization with the communication control apparatus 100 to the communication control apparatus 100 according to a first transmission procedure for maintaining the synchronization, while transmitting the signal to the communication control apparatus 100 according to a second transmission procedure indicating resource request when the determination unit 210 has determined to make resource request.

24. A resource allocation request method applied to a wireless communication system in which a communication control apparatus allocates resources used when a communication terminal apparatus performs wireless transmission to said communication control apparatus, wherein:
-
said communication terminal apparatus transmits a signal used to maintain time/frequency synchronization between said communication terminal apparatus and said communication control apparatus to said communication control apparatus according to a first transmission procedure for maintaining said synchronization, while transmitting said signal to said communication control apparatus according to a second transmission procedure representing a resource request when requesting said resources; and
on the other hand transmits said signal to said communication control apparatus according to a second transmission procedure indicating resource request when requesting said resources; and
said communication control apparatus detects that said signal has been transmitted according to said second transmission procedure when receiving said signal from said communication terminal apparatus,performs scheduling for allocating new resources to said communication terminal apparatus, and notifies said communication terminal apparatus of the result of said scheduling.
