Title:
SIGNAL TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/025110
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and apparatus. In said method, a terminal uses a first analog domain filter to filter a received first signal or a first signal to be sent. The center frequency point and/or passband bandwidth of the first analog domain filter is determined according to M sub-bands. The M sub-bands comprise a first sub-band and a second sub-band, the first sub-band being configured for uplink transmission on a first time domain resource, and the second sub-band being configured for downlink transmission on the first time domain resource. On the basis of the described solution, a downlink analog domain filter and an uplink analog domain filter employ the same design scheme, which can simplify the design of the filters, thereby reducing the implementation complexity for the terminal. When the center frequency points of the uplink analog domain filter and the downlink analog domain filter are the same, the delay in the terminal switching from sending a signal to receiving a signal or from receiving a signal to sending a signal can be reduced.
