Problems solved by technology

[0011] If the user terminal equipment is no longer limited in transmit power from a certain point in time, for example due to proximity to the base station, an excessive increase of the target value of the internal transmit power regulation loop will cause the transmit power of the E-DCH to be quickly overwhelmed by the user. Increased terminal equipment, which in turn leads to strong interference effects of parallel connections and consequent reduction of system capacity

Embodiment Construction

[0030] FIG. 1 shows by way of example a simplified structure of a radio communication system according to the known UMTS standard, wherein the method according to the invention can be implemented in the same manner in radio communication systems according to other standards.

[0031] The structure of the radio communication system according to the UMTS standard includes one or more mobile switching centers MSC (Mobile Switching Center), which carry out the switching of so-called circuit switched connections (English: Circuit Switched) and the management of various functions of the system. The mobile switching center MSC also takes over the transition to the public telephone network PSTN (Public Switched Telephone Network) (Public Switched Telephone Network). In addition to the mobile switching center there is a so-called gateway SGSN or GGSN (not shown), which enables the transition into a network with packet-oriented transmission, for example the Internet.

Abstract

The invention relates to a method for the regulation of transmission power of a user terminal in a radio communication system, whereby a scaling of a transmission power of a first channel is only carried out independently of a scaling of a transmission power of at least one second channel, when the regulation of the transmission power is not oriented to the first channel.

Description

technical field [0001] The invention relates to a method for controlling the transmission power of a subscriber terminal of a radio communication system, in particular a mobile radio system. Background technique [0002] In a radio communication system, for example the UMTS mobile radio system (Universal Mobile Telecommunication System (Universal Mobile Telecommunications System)) standardized within the framework of the 3GPP (Third Generation Partnership Project (Third Generation Partnership Project)), information (e.g. voice, image information or other data) are transmitted via a radio interface by means of electromagnetic waves. The radio interface is a connection between a base station and a subscriber terminal, where the subscriber terminal can be a mobile station or a stationary radio station. The radiation of the electromagnetic waves takes place here with a carrier frequency in the frequency band provided for the respective system. [0003] The current so-called En...
