Abstract

A method of controlling the data rate of transmitting data packets in a wireless communications system comprising a transmitter communicating with at least one receiver by means of radio communication signals employing at least one automatic repeat request (ARQ) or a hybrid ARC protocol. The data packets are allocated to at least one logical channel which is mapped on at least one physical downlink communication channel for transmission from the transmitter to the receiver. The receiver transmits signaling information relating to the receipt of said data packets in an uplink feedback channel to the transmitter. According to the invention, the data rate control is based on the receiver's current capability to process the amount of received data packets comprised in the communication signals. Further, the signaling information in the uplink feedback channel comprises a request to control the data rate in at least one logical channel. In addition, the invention relates to a receiver and transmitter adapted to carry out the control method.

Description

technical field

[0001] The invention relates to a method for controlling the data rate at which data packets are transmitted in a wireless communication system according to the preamble of claim 1, furthermore the invention relates to an adapted receiver and transmitter. Background technique

[0002] figure 1 The high-level structure of the Universal Mobile Telecommunications System (UMTS) is shown in . The network elements are divided into core network (CN), UMTS terrestrial radio access network (UTRAN) and user equipment (UE) according to function. The UTRAN is responsible for handling all radio related functionality, while the CN is responsible for routing calls and connections to external networks. The interconnection of these network elements is defined by open interfaces as can be seen in the figure. It should be noted that UMTS systems are modular and therefore it is possible to have several network elements of the same type.
