Patent ID: 8842564

Claim:
A method for allowing a communication terminal to configure a measurement gap pattern on a downlink carrier frequency for measurement on a target carrier frequency by the communication terminal, the communication terminal being capable of performing measurements on at least two downlink carrier frequencies without a measurement gap, the method comprising: obtaining an indication that there is a need for the measurement gap pattern for performing the measurement on the target carrier frequency; retrieving information about how to configure the measurement gap pattern; and determining, based on the retrieved information, which of the at least two downlink carrier frequencies the measurement gap pattern is to be configured on, wherein the measurement gap pattern could be configured on any of the at least two downlink carrier frequencies to perform the measurement on the target carrier frequency; wherein the retrieved information includes an indication of a specific downlink carrier frequency the measurement gap pattern is to be configured on, or includes at least one criterion to use for determining which of the at least two downlink carrier frequencies the measurement gap pattern is to be configured on.
