[0170] In some embodiments, an uplink (UL) symbol is inserted in a sub-band in a carrier bandwidth for transmitting a downlink (DL) symbol, or a DL symbol is inserted in a sub-band for transmitting a UL symbol, so that the sub-band can transmit the DL symbol and the UL symbol simultaneously, and a first gap is added between the UL symbol and the DL symbol to achieve uplink-downlink isolation, thereby greatly reducing self-interference between the uplink and the downlink of a transceiver and reducing the design difficulty of interference cancellation technology.

[0192] Optionally, the size of the first interval can be determined based on a value of the bandwidth, in a frequency unit, such as 2MHz or 3MHz, etc.

[0193] In an example, the value of the bandwidth is 2MHz, and the first interval has a size of 2MHz.

[0194] Optionally, the size of the first interval can be determined based on a relationship between the first interval and an interval threshold, such as determining the size by high-low information, such as high, indicating that the size of the first interval is greater than a certain preset value, and low, indicating that the size of the first interval is less than a certain preset value.

[0200] In some possible implementation manners, the first function is used to suppress the interference signal other than the first interval.

[0201] Optionally, the first capability can be an SBFD filter capability, which can indicate whether the terminal has a certain suppression capability for the interference signal outside the sub block gap.

[0202] Optionally, the terminal 101 can suppress the interference signal other than the first interval by a sub block filter.

[0205] The first ratio is greater than or equal to a ratio threshold, the first ratio being a ratio between powers of two adjacent sub-blocks, the two adjacent sub-blocks being two sub-blocks closest to the first interval respectively on two sides of the first interval.

[0207] Optionally, the first ratio can also be referred to as an adjacent sub-block leakage ratio.

[0208] In an example, FIG. 2c is a schematic diagram of the first ratio according to an example embodiment, as shown in FIG. 2c, the horizontal axis represents frequency, the vertical axis represents power spectral density (PSD), the two sub-blocks closest to the first interval on both sides of the first interval are two adjacent sub-blocks, the right lower diagonal filled area and the diamond filled area respectively represent the powers of the two adjacent sub-blocks, and the ratio between the powers of the two adjacent sub-blocks is the first ratio, i.e., the adjacent sub-block leakage ratio is greater than or equal to a threshold value. The adjacent sub-block leakage ratio can be defined as the ratio of the powers of the two adjacent sub-blocks (just one gap apart). In some embodiments, the capability information includes capability information of the terminal in a single frequency band.

[0209] Optionally, the capability information is indicated in units of frequency bands, such as the terminal reporting that it supports the SBFD sub-band full-duplex capability on frequency band A or the SBFD sub-band full-duplex capability on frequency band B, such as the terminal reporting that it supports the SBFD sub-band full-duplex capability on frequency band A and does not support the SBFD sub-band full-duplex capability on frequency band B, such as the terminal reporting that it supports the SBFD sub-band full-duplex capability on frequency band A and does not support the SBFD sub-band full-duplex capability on other frequency bands, or whether it supports the SBFD sub-band full-duplex capability on other frequency bands is not indicated in this report.

[0210] Optionally, in the scenario of band combination, the capability information of the terminal can also be indicated per band, i.e., indicated per band capability.
