FIELD: radio engineering, communication.
SUBSTANCE: invention discloses a method and a device in a base station (110) for estimating the amount of data to be received from a terminal (120). The base station (110) and the terminal (120) are contained in a wireless communication system (100). The terminal (120) has a buffer arranged in form of buffer frames containing data. The method involves determining (401) a service requested by the terminal (120); estimating (403) the time of arrival of data to be received from the terminal (120), based on the determined service; and setting (404) a buffer estimate containing an estimate of the amount of data to be received based on the estimated frame size for the determined service.
EFFECT: improved utilisation of radio resources.
