Abstract
A method and apparatus are provided for reporting a buffer status to a Node B, by a User Equipment (UE), in a mobile communication system. The method includes checking if a resource for data to be transmitted to the Node B is available, when there is a buffer status report triggered to be transmitted to the Node B; transmitting the buffer status report using the available resource, if the resource is available; and transmitting a scheduling request to the Node B, if the resource has not been allocated for a predetermined time duration.
Claims18
A method for reporting a buffer status to a Node B, by a User Equipment (UE), in a mobile communication system, the method comprising the steps of:
- checking if a resource for data to be transmitted to the Node B is available, when there is a buffer status report triggered to be transmitted to the Node B;
- transmitting the buffer status report using the available resource, if the resource is available;
- and
- transmitting a scheduling request to the Node B, if the resource has not been allocated for a predetermined time duration.
A User Equipment (UE) apparatus for reporting a buffer status to a Node B in a mobile communication system, the apparatus comprising:
- a transmission controller for checking if a resource for data to be transmitted to the Node B is available, when there is a buffer status report triggered to be transmitted to the Node B;
- and
- a transceiver for transmitting the buffer status report using the available resource, if the resource is available, and transmitting a scheduling request to the Node B if the resource has not been allocated for a predetermined time duration.
A method for receiving a buffer status report from a User Equipment (UE) by a Node B in a mobile communication system, the method comprising the steps of:
- if there is an available resource for uplink data to be received, receiving a buffer status report from the UE using the available resource;
- and
- if the resource has not been allocated for a predetermined time duration, receiving a scheduling request from the UE.
A Node B apparatus for receiving a buffer status report from a User Equipment (UE) in a mobile communication system, the Node B apparatus comprising:
- a receiver for receiving a buffer status report from the UE and receiving a scheduling request from the UE;
- and
- a resource allocation unit for allocating a resource to the UE,
- wherein if there is a resource for uplink data to be received, the receiver receives the buffer status report from the UE using the available resource, and if the resource has not been allocated for a predetermined time duration, the receiver receives a scheduling request from the UE.
