Abstract

Embodiments herein relate to a user equipment method and apparatus, wherein the user equipment receives In Device Coexistence (IDC) configuration information from the cellular communication network and determines, as a function of one or more Autonomous Denial configuration parameters indicated in the IDC configuration information, one or more radio measurement adaptations to be made for making a cellular radio measurement in compliance with a predefined performance requirement. Example adaptations include adapting any one or more of measurement times, measurement durations, and measurement periodicity. The user equipment advantageously performs the cellular radio measurement in accordance with the determined measurement adaptations.

Claims (16)

1. A method in a user equipment configured for operation in a cellular communication network, the method comprising:

receiving In Device Coexistence (IDC) configuration information from the cellular communication network;

determining, as a function of one or more Autonomous Denial configuration parameters indicated in the IDC configuration information, one or more radio measurement adaptations to be made for making a cellular radio measurement in compliance with a performance requirement that is predefined for the cellular radio measurement, said one or more radio measurement adaptations including any one or more of: adaptation of measurement times, adaptation of measurement durations, and adaptation of measurement periodicity; and performing the cellular radio measurement according to the determined radio measurement adaptations;

wherein determining the one or more radio measurement adaptations comprises adapting the measurement times at which measurement samples are taken for the cellular radio measurement to avoid, or at least minimize, overlapping with Autonomous Denial gaps created by the user equipment.

2. The method of claim 1 , further comprising sending signalling to a node in the cellular communication network, indicating the one or more radio measurement adaptations made with respect to the cellular radio measurement.

3. The method of claim 1 , wherein the performance requirement predefined for the cellular radio measurement directly or indirectly specifies that the cellular radio measurement be based on a certain number of measurement samples, wherein a measurement scheme is predefined for the cellular radio measurement, said measurement scheme defining a set of periodic measurement intervals over a defined measurement window, and wherein determining the one more radio measurement adaptations comprises modifying the measurement scheme such that one or more aperiodic measurement intervals are used by the user equipment, to thereby avoid making radio measurements during Autonomous Denial gaps created by the user equipment.

4. The method of claim 1 , wherein making the cellular radio measurement in compliance with the performance requirement predefined for the radio measurement is predicated on the IDC configuration information meeting one or more defined conditions for Autonomous Denial, and wherein the method further comprises, when the IDC configuration information does not meet the one or more defined conditions for Autonomous Denial, determining the one or more radio measurement adaptations for compliance with a lowered performance requirement.

5. A user equipment configured for operation in a cellular communication network and comprising:

a transceiver circuit configured for transmitting signals to and receiving signals from the cellular communication network; and

a processing circuit operatively associated with the transceiver circuit and configured to: receive In Device Coexistence (IDC) configuration information from the cellular communication network;

determine, as a function of one or more Autonomous Denial configuration parameters indicated in the IDC configuration information, one or more radio measurement adaptations to be made for making a cellular radio measurement in compliance with a performance requirement that is predefined for the cellular radio measurement, said one or more radio measurement adaptations including any one or more of: adaptation of measurement times, adaptation of measurement durations, and adaptation of measurement periodicity; and

perform the cellular radio measurement according to the determined radio measurement adaptations;

wherein the processing circuit is configured to determine the one or more radio measurement adaptations by adapting the measurement times at which measurement samples are taken for the cellular radio measurement to avoid, or at least minimize, overlapping with Autonomous Denial gaps created by the user equipment.

6. The user equipment of claim 5 , wherein the processing circuit is configured to send signalling to a node in the cellular communication network, indicating the one or more radio measurement adaptations made with respect to the cellular radio measurement.

7. The user equipment of claim 5 , wherein the performance requirement predefined for the cellular radio measurement directly or indirectly specifies that the cellular radio measurement be based on a certain number of measurement samples, wherein a measurement scheme is predefined for the cellular radio measurement, said measurement scheme defining a set of periodic measurement intervals over a defined measurement window, and wherein the processing circuit is configured to determine the one more radio measurement adaptations by modifying the measurement scheme such that one or more aperiodic measurement intervals are used to avoid making radio measurements during Autonomous Denial gaps created by the user equipment.

8. The user equipment of claim 5 , wherein the processing circuit is configured to make the cellular radio measurement in compliance with the performance requirement predefined for the radio measurement when the IDC configuration information meets one or more defined conditions for Autonomous Denial, and wherein, when the IDC configuration information does not meet the one or more defined conditions for Autonomous Denial, the processing circuit is configured to determine the one or more radio measurement adaptations for compliance with a lowered performance requirement.
