Abstract
A method for estimating an available bandwidth for each User Equipment (UE) in a mobile communication system comprises: a process of receiving estimated bandwidth information for at least one UE from an enhanced node B; a process of checking whether the estimated bandwidth information is received from a Medium Access Control (MAC) layer constituting said enhanced node B, or received through a Radio Link Control (RLC) layer or a Packet Data Control Protocol (PDCP) layer; a process of updating channel quality information using said estimated bandwidth information if it is checked that said estimated bandwidth information is received through the MAC layer; a process of updating an average value weighted with respect to the number of bytes of the bandwidth served by said enhanced node B using the estimated bandwidth information if it is checked that said estimated bandwidth information is received through the RLC or PDCP layer; and a process of calculating the bandwidth currently available by at least one UE using the updated channel quality information or the average value weighted with respect to the number of the bytes of the served bandwidth, and then transmitting the calculated ba…
