摘要：
Downlink control information, DCI, messages used for signaling downlink resource grants are employed for triggering sounding reference signal transmission in the uplink. An index of the uplink component carrier that should be used for the transmission is derived from SIB-2 linking between the downlink component carrier targeted by the downlink DCI message and one of the uplink component carriers configured for the mobile station, when the linking is available. In some cases the downlink component carrier targeted by the downlink DCI message is identified by a carrier identification field in the downlink DCI. Variants of the disclosed techniques involve a default uplink component carrier, which is used in the event that the SIB-2 based allocation is not possible or desired. The default uplink component carrier can be statically defined or semi-statically signaled by Radio Resource Control, RRC, signaling.
