METHOD AND DEVICE FOR CONTROLLING USER EQUIPMENT TO MEASURE NON-ACTIVATED DOWNLINK COMPONENT CARRIERS

摘要

The present invention provides a method and device for a user equipment (UE) to decide by itself to measure non-activated downlink component carriers, and a method and device for a base station to control a UE to measure non-activated downlink component carriers. The present invention also provides a method and device for a UE to request to send a sounding reference signal, and a method and device for a base station to control a UE to send a sounding reference signal. The aforementioned user equipment and base station are both in the wireless communication system based on carrier aggregation. The technical solution of the present invention can achieve the trade-off between the low power consumption of the user equipment and the fast accurate response to the component carriers.
