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