Embodiment Construction

[0036] As already explained above, proceed below, by means of the present invention should be realized, for example as figure 2 Shown in, packet-switched data transmission in a mobile radio system. here in figure 2 The communication between a base station 1 and a mobile station 2 of a mobile radio system, for example a UMTS mobile radio system, is shown by way of example. Information is transmitted from the base station 1 to the mobile station 2 via a so-called "downlink" channel DL, while information is transmitted from the mobile station 2 to the base station 1 via a so-called "uplink" channel.

[0037] The invention is described below by means of a packet-switched data transmission from the base station 1 to the mobile station 2, that is to say by means of a packet-switched data transmission of the "downlink coupling"-channel, wherein the invention can also be used analogously for the transmission of data via "Upcoupling" - channel for data transmission. In addition, t...

Abstract

Following transmission of a data packet, the transmitter (1) repeats packets to the receiver (2) as requested. Bit rate adaptation is undertaken before transmission. A matching pattern calculates parameter(s) signaled between transmitter and receiver, differentiating self-decoding and non self-decoding data packets. In at least one of these cases, differing bit rate adaptation patterns are signaled. An Independent claim is included for corresponding equipment.

Description

[0001] The application of the present invention is a divisional application of the patent application with the same name whose application date is December 27, 2002 and whose application number is 02826878.4. technical field [0002] The invention relates to a method for data transmission in a communication system, in particular a mobile radio system, according to an ARQ method, in particular a hybrid ARQ method, and a correspondingly arranged arrangement. Background technique [0003] Especially in connection with mobile radio systems, so-called packet access methods or packet-switched data connections are often proposed, since the types of messages received often have a very high burst factor, so that there are only short bursts interrupted by long static intervals. activity cycle. In this case, a packet-switched data connection can significantly increase efficiency compared to other data transmission methods in which a continuous data stream is involved, because in a data...
