Power control and triggering of sounding reference signal on multiple component carriers

Abstract:

Various devices, methods, and processes are provided for handling conflicting and/or redundant power control and triggering information for transmitting reference signal(s) such as sounding reference signal (SRS) using carrier aggregation (CA). A user equipment (UE) receives a first downlink control information (DCI) and a second DCI including SRS control information that is in conflict with that of the first DCI, for controlling SRS transmission on a component carrier (CC). The UE determines a resolution to reconcile the conflict between the DCIs. Then the UE can transmit an SRS on the CC in accordance with the resolution.
