Transmission pattern for the transmission of data in a radio communications system

Abstract

The subject matter of the invention is a method for the transmission of data between base stations and terminal devices in a radio communications system. The method uses at least one first time-frequency-spectrum which contains a plurality of transmission resources (res1; res2). A transmission resource (res1; res2) is defined by means of a section of the time-frequency-spectrum, which is formed by at least one subcarrier subdivided into time slots (st1-st4) and by at least one time slot (ts1-ts8). As part of the method, data are transmitted between a base station and a terminal device in a frame (fr1, fr2) on one transmission resource. The inventive method is characterized in that the base station transmits the data in such a way that a combination of subcarriers and / or time slots of the transmission resource used for the transmission of the frame forms a transmission pattern (p1; p2) characterizing the nature of the data. The base station selects the transmission pattern from a number of previously defined transmission patterns, depending on the nature of the data to be transmitted.

Description

technical field [0001] The invention relates to a method and arrangement for avoiding interference in a cellular radio communication system. Background technique [0002] Interference avoidance is of great importance in future cellular radio communication systems, especially in mobile radio communication systems such as the Universal Mobile Telecommunications System (UMTS). In addition to intracellular interference and inter-sector interference, the focus of avoiding interference is to avoid inter-cell interference. In this case, the interference between the individual cells can basically be divided into two groups, for example in a mobile radio communication system with a plurality of base stations. One base station defines one radio cell. In the vicinity of a base station located in the center of a radio cell, interference is caused by the radiation of a large number of neighboring base stations. But this first set of interferences is lower in strength compared to the s...

Problems solved by technology

[0005] Usually, however, the assumption of constant traffic load is not valid

For example, in packet-oriented transmission methods it is almost impossible to predict the actual traffic load in a radio communication system

Several methods have been proposed to limit the processing leeway of the scheduler for such systems, however these methods also bring about major disadvantages, such as severe loss of flexibility and high management overhead

[0006] Another disadvantage is that resource allocation based on subsequent transmissions cannot take into account that the traffic load may change completely during the period of the next transmission
