1. A resource allocation method of an enhanced node B (eNB) in a wireless communication system, the resource allocation method comprising:
- determining whether transmission control protocol (TCP) data to be transmitted to a user equipment (UE) requires a TCP acknowledgement signal;
transmitting the TCP data on downlink resources;
estimating a buffered amount for a transmit buffer of the UE when a predetermined time from the transmission of the TCP data is passed if the TCP data requires the TCP acknowledgement; and
allocating uplink (UL) resources for transmitting the TCP acknowledgement based on the estimated buffered amount.

Abstract
According to the present invention, a base station determines from a wireless communication system whether data to be transmitted is a response signal-required data that requires a response signal, estimates the amount of buffer of a user equipment (UE) at the point when the response signal is to be transmitted, predicts a required resource amount of the UE that is required for transmitting the response signal by using the buffer amount of the UE that is estimated, and schedules for allocating a resource to the UE on the basis of the required resource amount that is predicted.

8. A resource allocation apparatus of an enhanced node B (eNB) in a wireless communication system, the resource allocation apparatus comprising:
-
a transmitter configured to transmit transmission control protocol (TCP) data; a receiver configured to receive from a user equipment (UE) a TCP acknowledgement of the transmitted TCP data; and at least one processor configured to; determine whether the TCP data to be transmitted to the UE requires the TCP acknowledgement signal, estimate a buffered amount of the UE when a predetermined time from the transmission of the TCP data is passed if the TCP data to be transmitted to the UE requires the TCP acknowledgement, and allocate required uplink (UL) resources for transmitting the TCP acknowledgement based on the estimated buffered amount. - View Dependent Claims (9, 10, 11, 12, 13, 14)
