Problems solved by technology

This would make the mutual interconnection of radio stations and very high additional signaling costs unavoidable
Furthermore, the overall capacity of the radio communication system is reduced due to users and mobile stations staying in such soft handover areas

Embodiment Construction

[0016] According to attached figure 1 The radio communication system has at least one switching device VE, which is networked with other switching devices and establishes a network transition with the fixed network PSTN. The switching device is connected to at least one radio sub-controller BSC, which in turn is connected to the radio station BS. Between the radio station BS and the mobile station MS there is a radio interface via which, for example, three connected subscriber signals are transmitted.

[0017] Furthermore, the operation and maintenance center OMC belongs to the radio communication system, which is connected to the switching center VE and / or the radio control BSC and is used for monitoring the power parameters of the radio communication system and for maintenance and troubleshooting. O&M centers can also be considered only for sub-components of radiocommunication systems, such as radio sub-systems.

[0018] For the radio interface between the radio station BS...

Abstract

The invention relates to channel allocation in a radio communication system with time slots. The downlink radio channel (tsx) is allocated by the radio station (BS) depending on a channel allocation pattern (CAP) of a mobile station (MS) indicating the output power for the time slots. Allocation by the mobile station (MS) of the radio channel (tsx) is corrected under the control of the mobile station depending on an interference pattern (IP) indicating the interference power of the time slots. Output power is almost evenly distributed on the existing time slots by the radio station for downlink transmission by conducting allocation depending on time slot occupation in accordance with the channel allocation pattern. Soft-handover and its disadvantages are prevented when combined with mobile station controlled correction for the allocated time slot, even when the interference-critical frequency reuse spacing (cluster reuse) equals one.

Description

technical field [0001] The invention relates to a method for assigning radio channels in a radio communication system in which each radio channel consisting of at least one time slot is used for information transmission, and to a corresponding radio communication system. Background technique [0002] In radio communication systems, the allocation of radio channels (channel allocation) to mobile stations is generally carried out by radio stations, which provide the mobile stations and radio subscribers with radio technology in the radio cells to which they belong. The information is transmitted via the radio interface on assigned radio channels each consisting of one or more time slots. Problems arise in channel allocation if mobile stations and / or radio stations interfere with each other and interference occurs between mobile stations and radio stations. Especially when the frequency repetition distance (repeated string) of the radio communication system is equal to one, so...
