- DC Direct Connection
- the uplink signals of these carriers may interfere with the downlink received signals of some carriers, which reduces the success rate of data transmission.
- carrier F1 is operating in the low frequency band and carrier F2 is operating in the high frequency band
- three different types of mutual interference may exist:
- the first type of mutual interference is: carrier F1 and carrier F2 are both uplink carriers, and the frequency of a certain order intermodulation (IM) of carrier F1 and carrier F2 overlaps or partially overlaps with the downlink signal frequency of a certain carrier F3. .
- carriers F1 and F2 constitute interference to F3.
- F3 may be one of the carriers F1 or F2, or another carrier different from F1/F2 (at this time)
- the terminal may work on more than two carriers at the same time). For example, if the terminal device is configured with both LTE carriers of Band 1 and Band 7 and NR carriers (3400-3800 MHz), if the uplink (UL) of band 7 and the UL of NR are simultaneously transmitted, the 5th-order intermodulation effect generated by the terminal device is affected. It will affect the downlink (DL) receiver sensitivity of band 1.
- the second type of mutual interference is: the carrier F1 is an uplink carrier, the carrier F2 is a downlink carrier, and the frequency multiplication of the carrier F1 overlaps or partially overlaps with the frequency of the carrier F2. Then carrier F1 constitutes harmonic interference to carrier F2.
- LTE Band 3 has a bandwidth of 1710-1785 MHz and a second-order harmonic range of 3420-3570 MHz. If a terminal performs LTE uplink transmission on band 3 and DL reception on NR band 3400-3800 MHz at the same time, the second-order harmonic may interfere with the sensitivity of the NR DL receiver.
- carrier F1 is a downlink carrier
- carrier F2 is an uplink carrier
- the frequency multiplication of carrier F1 overlaps or partially overlaps with the frequency of carrier F2.
- carrier F2 forms a harmonic mixing interference with F1.
- LTE Band 3 has a downstream 1805-1880 MHz with a second-order harmonic range of 3610-3760 MHz. If a terminal performs LTE downlink reception on band 3 and uplink transmission on NR band 3400-3800 MHz, the second-order harmonic intermodulation of NR may interfere with the sensitivity of LTE DL receiver.
- the estimation of the severity of the self-interference problem is based on the assumption of 23dbm (the maximum transmit power of the terminal).
- 23dbm the maximum transmit power of the terminal.

- First transmit power The transmit power used by the terminal device to transmit uplink data. That is, the first transmit power is a transmit power that needs to be determined before the terminal device sends the uplink data.
- the second transmit power may be any transmit power that is less than the maximum transmit power that the terminal device can support.
- the terminal device may determine a limited maximum transmit power (ie, a second transmit power) according to the anti-interference capability of the terminal device, where the limited transmit maximum transmit power is smaller than a maximum transmit power that the terminal device can support.
- the anti-interference capability of the terminal device may be the transmission power determined by the terminal device according to the internal interference level of the terminal device. In other words, the terminal device transmits uplink data below the limited maximum transmission power, and the interference level to the receiving end can be reduced to a level that the receiving end can tolerate. That is to say, when the terminal device simultaneously transmits and receives data, the transmission power should be below the limited maximum transmission power, thereby ensuring that the terminal device can correctly demodulate the received data.
- the terminal device may determine the first transmit power according to the second transmit power and the third transmit power.
