Methods and systems for scheduling resources in a telecommunication system

Abstract

Scheduling requests are transmitted from a mobile terminal to a base station. The mobile sends a first scheduling request to the base station, the first scheduling request being associated with first data to be transmitted to the base station. The mobile receives a scheduling grant from the base station in response to the first scheduling request and transmits a buffer status report to the base station in response to receiving the scheduling grant. An HARQ acknowledgment for the buffer status report is received. Second data is received for transmission to the base station while at least some of the first data is waiting to be transmitted to the base station. A change in a buffer status of the mobile terminal is detected indicating that the second data has higher priority than the first data. The mobile transmits a second subsequent scheduling request to the base station in response to the change in buffer status.

What is claimed is: 
     
         1 . A method for transmitting scheduling requests from a mobile terminal to a base station, the method comprising:
 sending a first scheduling request to the base station, wherein the first scheduling request is associated with first data to be transmitted to the base station;   receiving a scheduling grant from the base station in response to the first scheduling request;   transmitting a buffer status report to the base station in response to receiving the scheduling grant;   receiving from the base station a Hybrid Automatic Repeat Request (HARQ) acknowledgment (ACK) for the buffer status report;   receiving second data for transmission to the base station while at least some of the first data is waiting to be transmitted to the base station;   detecting a change in a buffer status of the mobile terminal indicating that the second data has higher priority than the first data; and   transmitting a second subsequent scheduling request to the base station in response to the change in buffer status.
