Embodiment Construction

[0037] as from image 3It is clearly seen that an exemplary mobile radio communication system comprises a large number of mobile switching centers MSC which are networked with each other or which establish access to the fixed network PSTN. Furthermore, the mobile switching centers MSC are each connected to at least one device RNM for allocating radio technology resources. Each such device RNM in turn enables a connection to at least one base station BS. The term base station can here also be understood in the broadest sense only as the location of, for example, transmitting antennas. Such a base station BS can establish connections via a radio interface to other radio stations, for example mobile stations MS or other mobile or stationary terminals. Each base station BS establishes at least one radio cell Z. In a sectorized or hierarchical cell structure, each base station BS can also manage a number of radio cells Z, for example a partition around the base station BS.

Abstract

The invention relates to a method for controlling upwards link / downwards link transitions in the channel allocation in a transmission frame for transmitting information in a communications system with a plurality of cells. According to said method, a switching instant between upward link and downward link (UL / DL) transitions is controlled in tune with the respective switching instant of adjacent cells in such a way that the same upwards and downwards links are given in immediately adjacent cells. The upwards and downwards link within individual adjacent cells or groups of cells can be controlled according to the load through the variable selection of possibly, several switching instants and / or resources of the individual cells that are activated. The cells are preferably organised in a cluster of three or four and several temporally variable switching points (one per cell), with an alternating upwards and downwards link change for successive cell specific channel allocations within the transmission frame, are used.

Description

technical field [0001] The invention relates to a method for controlling channel allocation in a transmission frame having a large number of channels for information transmission in a communication system having a large number of cells. Background technique [0002] In wireless communication systems, information (for example speech, image information or other data) is transmitted by means of electromagnetic waves via a radio interface between transmitting and receiving radio stations (base stations or mobile stations). The emission of the electromagnetic waves takes place here with a carrier frequency which lies within a frequency band predetermined for the relevant system. In GSM (Global System for Mobile Communications) the carrier frequency is located in the 900, 1800 or 1900 MHz frequency band. For future mobile radio networks using the CDMA or TD / CDMA transmission method via a radio interface, for example UMTS (Universal Mobile Telecommunications System) or other syste...
