Abstract
A passive intermodulation elimination method, an apparatus, and a base station are disclosed. The method includes: receiving, by a network device, N pieces of backhauled information, where one piece of the backhauled information includes initial phase information of each carrier on one transmit channel, and N is an integer greater than or equal to 1; and eliminating, by the network device, a PIM of a received signal on a receive channel on the network device based on the N pieces of backhauled information.
