Abstract
In one exemplary aspect of this invention a method includes buffering data in a user equipment and, in response to an amount of buffered data exceeding a threshold value, triggering the generation of a buffer status report and the sending of the buffer status report to a network access node, where the threshold value is a function of the capacity of a currently allocated uplink data transmission resource and some certain amount of time. In another exemplary embodiment the triggering of the generation of the buffer status report and the sending of the buffer status report to a network access node occurs when an amount of buffered data in a buffer of a particular logical channel group exceeds a maximum value associated with one of a plurality of buffer status report tables that is currently in use.
