Abstract:
1. A method, comprising: 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 re-port 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; where triggering the generation of a buffer status report 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; where the user equipment selects the buffer status report table that is currently in use according to an amount of buffered data by selecting the buffer status report table that has the smallest maximum value that does not exceed the amount of currently buffered data; and further comprising identifying the selected buffer status report table to the network access node using at least one bit in a medium access control buffer status report header.
