A method for controlling communication overhead from a user equipment to a base station. The base station determines a granularity level of an amount of information about a buffer status of a user equipment buffer. The base station makes the determination based on at least one variable parameter. The determined granularity level is sent to the user equipment, and received thereby. The buffer status is sent to the base station from the user equipment in accordance with the determined granularity level.
