Currently, in the prior art, a frequency multiplication or frequency intermodulation relationship exists between a main frequency band (e.g., an N78 frequency band) in a 5G network and some frequency bands in an LTE network, so that mutual interference between the frequency bands is easily generated, and thus, the transmission performance of a terminal device is poor.

it is to be understood that the first set of noise values includes at least one noise value, and one noise value is a noise value between one receiving antenna and one transmitting antenna or between multiple transmitting antennas.
It should be noted that the above N receiving antennas may be understood as one receiving antenna group, that is, the one receiving antenna group includes N receiving antennas, and N and M may be the same or different.
Optionally, in the embodiment of the present invention, when the terminal device performs dual connection between the LTE network and the 5G network, the terminal device may obtain the first noise value set.
Optionally, in the embodiment of the present invention, the N receiving antennas may be antennas corresponding to an LTE network, and the M transmitting antennas may be antennas corresponding to a 5G network; or, the N receiving antennas may be antennas corresponding to a 5G network, and the M transmitting antennas may be antennas corresponding to an LTE network.

Step 201c, the terminal device determines a first noise value set according to the first measurement value and the second measurement value.
In this embodiment of the present invention, the terminal device may determine a difference between the first measurement value and the second measurement value as the first noise value set.

Optionally, in the embodiment of the present invention, the terminal device may set a frequency band range (i.e., a target frequency band range) of the received RSSI, so as to detect a received signal strength value in the frequency band range. For example, the frequency band of the RSSI may range from 3300MHz to 3800 MHz.
Step 202, the terminal device determines, according to the first noise value set, at least one group of antennas corresponding to a target noise value satisfying a preset condition in the first noise value set as a target antenna group.

It is to be understood that the above-mentioned target noise value may include at least one noise value, and all of the at least one noise value are less than a preset threshold value. The terminal device may determine at least one group of antennas corresponding to the at least one noise value as a target antenna group, and one noise value corresponds to one group of antennas.
Optionally, in this embodiment of the present invention, the terminal device may determine, according to the first noise value set, a group of antennas corresponding to a minimum noise value in the first noise value set as a target antenna group.
Optionally, in this embodiment of the present invention, the first set of noise values includes at least one noise value, and each noise value in the at least one noise value corresponds to a group of antennas respectively. The terminal device may select a minimum noise value from the first noise value set, and then determine a group of antennas corresponding to the minimum noise value as a target antenna group.
