Abstract: An arrangement (124) and method (310-360) for Transmission Control Protocol (TCP) flow control in a communication system, by: determining delay in a transmit buffer of the system; and modifying TCP window size dependent on the determined delay. An indication of modified TCP window size is preferably sent to a TCP server (140) of the system in an acknowledge packet (310). The invention is particularly suitable for TCP flow control in wireless communication systems (e.g., UTRA) systems, and has the advantage that RTT (i.e., the latency of the system) can be substantially guaranteed, irrespective of the throughput that a user is allocated.

Abstract: A method and arrangement for fair control of resources amongst users with different instantaneous throughputs in a radio communication system such as a UMTS system. Respective indications of users among whom resources are to be allocated are placed in a ‘round robin’ queue (200) and each user whose indication is at the head of the queue is allocated a number of resource units as a function of: ?, a predetermined parameter determining the extent to which a fixed number of resource units should be allocated to the user and the extent to which a fixed volume of data should be transferred from/to the user; ?, the volume of data that the user is allowed to transfer if ?=1; ?, the number of resource units that can be allocated if ?=0; and ?, the number of information bits per resource unit that can be transferred to/from the user. This provides the following advantages: the resources can be allocated in the manner chosen by the operator. the function requires very few input parameters, and so is simple to operate.
