Abstract

The method is based on the capability for coordination of the radio activities of two mobile radio transmitting and/or receiving devices (3, 4). In the case of the method, a value of at least one characteristic variable (P_RSSI,BT, N; 15, 16, 17) is first of all determined, which is characteristic of the requirement for coordination of the radio activity of one or both transmitting and/or receiving devices. The coordination of the radio activity of one or both transmitting and/or receiving devices is then activated or deactivated as a function of the value.

Claims

a) determining a value of at least one characteristic variable which is characteristic of the requirement for coordination of the radio activity of the first transmitting and/or receiving device and/or for the coordination of the radio activity of the second transmitting and/or receiving device; and

b) activating or deactivating the coordination of the radio activity of the first transmitting and/or receiving device and/or of the coordination of the radio activity of the second transmitting and/or receiving device as a function of the value of the at least one characteristic variable.

3. The method as according to claim 1, wherein the determination of the value of the at least one characteristic variable and the activation and deactivation, the coordination of the radio activity of the first transmitting and/or receiving device, and the coordination of the radio activity of the second transmitting and/or receiving device are carried out by that of the two transmitting and/or receiving devices which has a lower typical output power.

4. The method as according to claim 1, comprising the following method steps:

a1) determining a value for at least one first characteristic variable by the second transmitting and/or receiving device, which is characteristic of the requirement for coordination of the radio activity of the first transmitting and/or receiving device;

a2) determination of a value for at least one second characteristic variable by the first transmitting and/or receiving device, which is characteristic of the requirement for coordination of the radio activity of the second transmitting and/or receiving device;
