For example, low frequency bands may include frequency bands (BAND): B5, B8, . . . (sub-1 G frequency bands); middle frequency bands may include BANDs: B1, B2, . . . (1 G to 2 G frequency bands); high frequency bands may include BANDs: B40, B41, . . . (2 G to 6 G frequency bands); and millimeter-wave corresponds to BANDs above 6 G. The foregoing correspondences between frequency bands may be configured by using a (non-volatile (NV)) entry in a configuration file. Configurations vary according to types of radio frequency front end modules of different products. The file shown in Table 1 is stored in a memory, and may be accessed by the arbitration apparatus.

In the foregoing example, the table of frequency bands that do not conflict indicates frequency bands that do not conflict and that are corresponding to different MODEMs. Optionally, the arbitration apparatus may also establish a table of frequency bands that conflict, that is, indicate frequency bands that conflict and that are corresponding to the two MODEMs. Alternatively, the arbitration apparatus may also establish a complete table including the table of frequency bands that conflict and the table of frequency bands that do not conflict, that is, indicate frequency bands that do not conflict and frequency bands that conflict. This is not specifically limited herein.
