According to the invention, transmissions of the second radio station are received in the first radio station in which the operating instruction for transmission power of the second radio station is determined. The operating instruction is transmitted during a following transmission of the first radio station to the second radio station, whereupon the latter takes into account the operating instruction for power regulation during one of its following transmissions. Contrary to prior art, no time invariable or fixed step size is used. An operating instruction is used instead which is related to a variable step size in transmission power regulation. The variable step size is subscriber-dependent and time-dependent regulated by the radio stations. |

DETAILED DESCRIPTION The mobile radio system shown in FIG.
1 as an example of a radio communication system consists of a multiplicity of mobile switching centers MSC which are networked together and, respectively, establish access to a landline network PSTN.
These mobile switching centers MSC are also connected to in each case at least one facility RNM for allocating radio resources.
Each of these facilities RNM, in turn, provides for a connection to at least one base station BS.
Such a base station BS can set up a connection to subscriber stations, e.
g.
mobile stations MS or other mobile and stationary terminals via a radio interface.
Each base station BS forms at least one radio cell.
FIG.
1 shows a connection V transmitting user information between a base station BS and a mobile station MS.
A system for transmission power control of the radio link via this radio interface will be explained later, only the transmission power adjustment of the mobile station MS being shown.
Equivalent measures can be used for the reverse direction of transmission.
An operation and maintenance center OMC effects control and maintenance functions for the mobile radio system or parts thereof.
The functionality of this structure can be transferred to other radio communication systems in which the invention can be used, especially for subscriber access networks with wireless subscriber access.
The transmission power control is shown for radio transmission in the up-link UL.
Transmission means TX of the mobile station MS send information in the up-link UL, a transmission power correction instruction TPC being taken into consideration for adjusting the transmission power.
This transmission power correction instruction TPC is produced by receiving means RX in the base station BS receiving the transmissions of the mobile station MS and control means MPC determining the transmission power correction instruction TPC which is then transmitted to the mobile station MS in the down-link DL.
The transmission power of the mobile station MS is not changed arbitrarily but in increments
