Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further described in more detail.
Embodiment one,
The embodiments of the invention provide a kind of method for transmitting signals, applied to base station, as shown in Fig. 2 methods described includes：
Step 201：Downlink transmission frame is chosen, determines the first guard period (GP, Guard in the downlink transmission frame
Period)；
Step 202：At least one downstream signal is set in the first GP；
Step 203：The downlink transmission frame is sent to terminal device.
The basic thought of this motion is that, for the GP1 in above-mentioned downlink transmission frame, the GP2 in uplink transmission frame, these are exempted from
Jamming resource carries out particular design.Can be specifically, it is contemplated that downgoing control signal, such as descending solution preferentially are set in GP1
Call reference signal (DMRS, Demodulation Reference Signal), CSI-RS, nonopiate etc. more sensitive to disturbing
Earth signal is transmitted, it is contemplated that up DMRS, uplink control signal, nonopiate etc. are preferentially carried out on GP2 to disturbing more sensitively
Signal transmits.
Further, it is contemplated that the modulating-coding grade of institute's carrying signal on lifting downlink transfer GP1, uplink GP2,
With further lifting system efficiency.
