Methods and systems for scheduling resources in a telecommunication system

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.
