Abstract

The method is based on the capability for coordination of the radio activities of two mobile radio transmitting and/or receiving devices. In the case of the method, a value of at least one characteristic variable 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

1. A method, comprising:

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

activating or deactivating the coordination of radio activity of the first transceiver device and/or of the coordination of radio activity of the second transceiver device as a function of the value of the at least one characteristic variable, the activating and deactivating to be performed by a one of the first or second transceiver devices having a lower output power.

2. The method as according to claim 1, wherein the at least one characteristic variable is at least an input-signal level, a data error rate, a bit error rate, or a packet error rate.

3. The method as according to claim 1, wherein the at least one characteristic variable which is determined by the one of the two transceiver devices is at least one of the variables:

a statement as to whether or not a radio link is present, or

a number of the channels or channel pairs which are classified as being good or poor in a radio link.

4. An apparatus, comprising

at least one determination means for determination of at least one characteristic variable which is characteristic of the requirement for coordination of radio activity of the a transceiver device and/or for the coordination of radio activity of a second transceiver device;

and

at least one switching means for activation or deactivation of the coordination of the radio activity of the first transceiver device and/or of the coordination of radio activity of the second transceiver device as a function of the at least one characteristic variable, the at least one switching means associated with a one of the first or second transceiver devices having a lower output power.

5. The apparatus according to claim 4, wherein the at least one characteristic variable is an input-signal level or a data error rate, a bit error rate, or a packet error rate.

6. The apparatus according to claim 4, wherein the at least one determination means is associated with the one of the first or second transceiver devices having the lower output power.

7. The apparatus according to claim 4, wherein the at least one characteristic variable which is determined by the one of the two transceiver devices is at least one of the variables:

a statement as to whether or not a radio link is present based, or

a number of the channels or channel pairs which are classified as being good or poor in a radio link.

8. The apparatus according to claim 4, wherein the two transceiver devices are integrated in a common appliance.
