Abstract: A terminal determines a first band of a primary card and a second band of-a secondary card; if the secondary card does not support the first band, determines a first identifier and a second identifier of a first 2R path and a third identifier and a fourth identifier of a second 2R path based on the second band, and determines a fifth identifier and a sixth identifier of a third 2R path based on the first band, where the first identifier, the third identifier, and the fifth identifier are identifiers of primary receive paths, and the second identifier, the fourth identifier, and the sixth identifier are identifiers of diversity receive paths; and determines, based on those identifiers, and a selection condition stored in the terminal, to communicate with the second base station through the secondary card by using the first 2R path or the second 2R path.
