Abstract
A base station comprises an RNC message receiver which receives data packets from a Radio Network Controller, RNC. The data packets are transmitted over air interface channels by a transmitter. The base station includes buffer memory for buffering the data packets prior to transmission, a scheduler for scheduling the data packets for transmission over the air interface channels, and a memory allocator for determining a first memory allocation of the buffer memory for a first air interface communication with a first user equipment. The base station further includes a flow controller for determining a transfer allowance for transferring of data from the RNC to the base station in response to the first memory allocation and a current buffer memory usage of the first air interface communication. The transfer allowance is transmitted to the RNC by an RNC message transmitter for achieving an efficient flow control.
