Communication method, base station, communication system, and mobile terminal

Abstract

In accordance with the present invention, in a case of using persistent scheduling, when detecting a transition from a talk state to a silent state, resources to be allocated during a silent state are allocated to a channel exclusive for silent period, and the resources which have been allocated to a mobile terminal during the talk spurt are released. Therefore, the useless allocation of resources can be reduced, and the throughput of the system can be improved.

         4 . A mobile communication system for performing radio communication between a mobile terminal and a base station by using dynamic scheduling of performing scheduling dynamically and persistent scheduling of performing scheduling persistently, wherein
 a radio resource allocated for radio communication performed by using the dynamic scheduling is notified from said base station to said mobile terminal by using a control signal of a lower layer, and   a radio resource allocated for radio communication performed by using the persistent scheduling is notified from said base station to said mobile terminal by using a control signal of a upper layer.   
     
     
         5 . The mobile communication system according to  claim 4 , wherein occupation of the radio resource allocated for radio communication performed by using the persistent scheduling is notified from said base station to said mobile terminal by using a control signal of the lower layer. 
     
     
         6 . The mobile communication system according to  claim 4 , wherein release of the radio resource allocated in the persistent scheduling is notified from said base station to said mobile terminal by using a control signal of the lower layer. 
     
     
         7 . The mobile communication system according to  claim 4 , wherein the radio resource allocated for radio communication performed by using the persistent scheduling is allocated for downlink communication. 
     
     
         8 . The mobile communication system according to  claim 4 , wherein the radio resource allocated for radio communication performed by using the persistent scheduling is allocated for uplink communication. 
     
     
         9 . A base station for performing radio communication with a mobile terminal by using dynamic scheduling of performing scheduling dynamically and persistent scheduling of performing scheduling persistently, wherein
 said base station notifies said mobile terminal of a radio resource allocated for radio communication performed by using the dynamic scheduling by using a control signal of a lower layer, and   notifies said mobile terminal of a radio resource allocated for radio communication performed by using the persistent scheduling by using a control signal of a upper layer.   
     
     
         10 . A mobile terminal for performing radio communication with a base station by using dynamic scheduling of performing scheduling dynamically and persistent scheduling of performing scheduling persistently, wherein
 said mobile terminal receives a radio resource allocated for radio communication performed by using the dynamic scheduling and transmitted from said base station by using a control signal of a lower layer, and   receives a radio resource allocated for radio communication performed by using the persistent scheduling and transmitted from said base station by using a control signal of a upper layer.
