Abstract
The present invention provides a method for transmitting reference signals comprising: during carrier aggregation, a user equipment sending physical uplink shared channel (PUSCH) on one or more component carriers, and sending demodulation reference signals (DM RS) for the PUSCH on each section of bandwidth occupied by the PUSCH on each component carrier, wherein a DM RS sequence on a section of bandwidth is an independent sequence or part of an independent sequence and forms an independent sequence with DM RS sequences on multiple sections of bandwidth other than the section of bandwidth; the section of bandwidth is a section of continuous bandwidth occupied by the PUSCH on any component carrier, or is any of the multiple sections of bandwidth occupied by the PUSCH on any component carrier. The Present invention further provides a corresponding apparatus.
