  • time-frequency resources As shown in Figure 11, it shows a schematic diagram of time-frequency resources for downlink signal measurement involved in this application; the base station staggers the time-frequency resources used by the terminal for measurement with downlink signals such as broadcasting, and the terminal performs measurements on these target time-frequency resources to avoid the impact of downlink signals on the measurement results.

  • the base station will configure the terminal to measure the received signal strength with and without harmonic interference. The details are as follows:
  • the base station configures the aforementioned downlink signal measurement time-frequency resources to the terminal, and the terminal measures the noise on band B to obtain noise power;
  • the base station configures the frequency band combination band A+band B for the terminal, and activates band A or band B or both band A and band B according to the interference generation mechanism to generate an interference signal for the terminal to measure the interference intensity;
  • band A transmission interferes with band B reception, so only band A transmission needs to be activated. If it is intermodulation interference, such as intermodulation of band A+band B interfering with band B reception, then both band A+band B transmission signals need to be activated at the same time.

  • the terminal reports the interference strength information, where the interference signal strength information can be the noise power and interference+noise power obtained by the above measurement, or it can be the difference between the two (the difference can represent the MSD size).

  • MSD_xx MSD_xx
  • the MSD results can be reported in intervals, as shown in Table 3 below, with 3dB as the step interval, to determine the interval range in which the actual MSD is located, and report the capability class corresponding to the interval to reduce signaling overhead.
  • the MSD situation can be obtained by calculation, that is, (interference+noise power)-noise power.
  • the base station can take certain measures to avoid interference. For example, for the frequency band combination A+B, where A has harmonic interference with B, the base station avoids the state where one band A and one band B are transmitting and one band B is receiving during scheduling. For another example, for the frequency band combination A+B+C, where the intermodulation information of A+B interferes with the C band, the base station can avoid intermodulation interference to the C band by not transmitting the A and B bands at the same time. Therefore, the above-mentioned actual interference measurement and reporting of the terminal can inform the base station of the actual interference situation of the terminal, thereby assisting the base station in scheduling, avoiding interference, and improving throughput.
  • this method based on real-time measurement of MSD or measurement of interference intensity and reporting can simplify the implementation complexity of the terminal and the load of signaling reporting.
  • the terminal does not need to distinguish the interference type and interference frequency band information, and only needs to follow the interference measurement window and interference reporting configuration configured by the base station to complete the interference/MSD evaluation, which is simple and fast.
  • the base station also does not need to remember the interference type, interference MSD value, interference frequency, etc. of each frequency band combination. When necessary, it only needs to configure the terminal to measure and report the corresponding frequency point of the corresponding frequency band combination to know the actual interference situation of the terminal, which is very convenient.
