Method for scheduling radio resources in mobile communication system
First Claim
1. A method for scheduling radio resources in a base station in a mobile communication system, the method comprising:
- allocating a number of radio resources to a first user equipment upon receiving resource requests from the first user equipment or pre-allocating resources to the first user equipment in the absence of receiving requests from the first user equipment;
transmitting information between the base station and the first user equipment using a portion of the number of allocated radio resources, wherein the portion of the number of allocated radio resources is less than the number of allocated radio resources;
receiving, from the first user equipment, a first message including a bit set to 1 indicating that information for transmission remains in a buffer of the first user equipment and also indicating that another portion of the number of allocated radio resources were not used during the transmission of the information;
de-allocating, from the first user equipment, all of the radio resources of the another portion of the number of allocated radio resources that were not used during the transmission of the information;
transmitting, to the first user equipment, a second message indicating that all of the another portion of the number of allocated radio resources that were not used during the transmission of the information have been de-allocated from the first user equipment;
re-allocating the de-allocated radio resources to a second user equipment; and
maintaining allocation, to the first user equipment, of the portion of the number of allocated radio resources that were used during the transmission of the information.

Abstract
A method for scheduling radio resources in a mobile communication system is disclosed. The method includes allocating radio resources to a specific User Equipment (UE), receiving a release request message of the allocated radio resources from the specific UE and re-allocating unused radio resources to other UEs other than the specific UE. The method according to the present invention can re-allocate unused radio resources to other UEs using a control signal received from a specific UE such that wasted radio resources are minimized and efficiency of data communication in a mobile communication system may be enhanced.

3. A method for scheduling radio resources in a user equipment in a mobile communication system, the method comprising:
-
receiving an indication of a number of allocated radio resources, from a base station, in response to requesting resources from the base station or the base station pre-allocating resources to the user equipment as necessary in the absence of requests from the user equipment; transmitting information between the user equipment and the base station using a portion of the number of allocated radio resources, wherein the portion of the number of allocated radio resources is less than the number of allocated radio resources; transmitting, to the base station, a first message including a bit set to 1 indicating that information for transmission remains in a buffer of the user equipment and also indicating that all of another portion of the number of allocated radio resources were not used during the transmission of the information; receiving, from the base station, a second message indicating that all of the another portion of the number of allocated radio resources that were not used during the transmission of the information have been de-allocated from the user equipment; maintaining allocation, in the user equipment, of the portion of the number of allocated radio resources that were used during the transmission of the information; and transmitting, to the base station, the information remaining in the buffer using the maintained portion of the number of allocated radio resources after receiving the indication that all of the another portion of the number of allocated radio resources that were not used during the transmission of the information have been de-allocated from the user equipment. - View Dependent Claims (4)
