Abstract:
A user equipment method, user equipment and a computer program product are disclosed. The user equipment method comprises: determining a first indicator indicative of a potential throughput for a channel between the user equipment and a base station when using a network assist interference suppression scheme; determining a second indicator indicative of a potential throughput for the channel between the user equipment and the base station without using the network assist interference suppression scheme; calculating an effective indicator indicative of an effective potential throughput for the channel between the user equipment and the base station based on the first indicator and the second indicator; and transmitting the effective indicator to the base station. In this way, rather than transmitting only an indicator of the potential throughput when not using the network assist interference suppression scheme or only transmitting an indicator which indicates the throughput when using the network assist interference suppression scheme, instead an effective throughput is transmitted which may be based on both of these indicators and so is likely to be more stable. Also, by only transmitting a single throughput indicator, the need for additional signalling to carry those additional indicators is avoided, which enables an improved indicator to be provided using existing signalling.
