Abstract

Apparatus and a corresponding method are provided, the apparatus being configured to enter a test mode and determine a maximum sensitivity degradation, MSD, value for a multi-carrier communication mode supported by the apparatus, wherein the MSD value is determined according to a radiated performance test.

First claim

1 . Apparatus comprising at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to:
enter a test mode; and determine a maximum sensitivity degradation, MSD, value for a multi-carrier communication mode supported by the apparatus, wherein the MSD value is determined according to a radiated performance test, wherein multiple MSD values for corresponding multi-carrier communication modes supported by the apparatus are determined.

2 . Apparatus according to claim 1 , wherein the MSD value is determined when antenna(s) associated with the corresponding multi-carrier communication mode were in an active state during the test mode according to the radiated performance test.

3 . Apparatus according to claim 1 , wherein the MSD value is determined when a transmitter of the apparatus operates at a maximum output power in an environment isolated from any network, wherein the apparatus is in a state that is not configured or controlled by the network.

4 . Apparatus according to claim 3 , wherein the MSD value is determined when a transmitter of the apparatus operates at maximum bandwidth.

5 . Apparatus according to claim 1 , wherein the MSD value is determined based on a measurement of a received signal strength indication, RSSI, value compared to a noise level.

6 . (canceled)

7 . Apparatus according to claim 1 , wherein the multiple MSD values include those for different permutations of antenna configurations for otherwise the same multi-carrier communication mode.

8 . Apparatus according to claim 1 , wherein multiple MSD values for the same multi-carrier communication mode are determined including one determined according to the radiated performance test and at least another not determined according to the radiated performance test.

9 . Apparatus according to claim 1 , and further configured to store the MSD value(s) in non-transient storage of the apparatus.

10 . Apparatus according to claim 9 , further configured to select, using the stored MSD value(s), a multi-carrier communication mode or an antenna configuration for a multi-carrier communication mode.

11 . Apparatus according to claim 1 , and further configured to transmit the MSD value(s) to a network.

12 . Apparatus according to claim 1 wherein the test mode is a factory test mode which is disabled when the apparatus either leaves the factory or is operative in the field.

13 . Apparatus according to claim 1 , and further configured to cooperate with an external test computer to perform the radiated performance test.

14 . Apparatus according to claim 13 , and further configured to receive from the external test computer information prescribing the conditions of the radiated performance test including at least one of the following:
multi-carrier communication mode configurations(s); different permutations of antenna configuration(s) for multi-carrier communication mode configuration(s); transmitter and receiver bandwidth configuration(s); and transmitter power.

15 . Apparatus according to claim 1 , which is a user equipment.

16 . (canceled)

17 . A method comprising:
entering a test mode; and determining a maximum sensitivity degradation, MSD, value for a multi-carrier communication mode supported by the apparatus, wherein the MSD value is determined according to a radiated performance test, wherein multiple MSD values for corresponding multi-carrier communication modes supported by the apparatus are determined.
