METHOD AND DEVICE FOR TRANSMITTING APERIODIC SOUNDING REFERENCE SIGNAL (SRS)

摘要

Embodiments in the present invention disclose a method and device for transmitting aperiodic Sounding Reference Signal (SRS). By applying the technical solution of the embodiments in the present invention, a Base Station (BS) performs quasi-static configuration of the aperiodic SRS on a mobile terminal through high level to decrease signaling overhead. On the one hand, different sub-frames can be configured with different or the same Cycle Shift (CS) and resource position to increase the system configuration flexibility; On the other hand, aperiodic SRS may be transmitted in multiple sub-frames to reduce system delay and increase detection bandwidth. Moreover, the relatively flexible timing mode can be configured in the terminal without bringing too many limits on the scheduling.
