US 12,368,628 B2 · Method for obtaining information about a channel and apparatus

Abstract

A method for obtaining information about a channel and a related apparatus are disclosed. The method includes: obtaining first feedback signals from a passive inter-modulation source; obtaining first update direction information based on the first feedback signals; and obtaining information about a channel with the passive inter-modulation source based on the first update direction information. According to the method and the apparatus, complexity of obtaining the information about the channel with the passive inter-modulation source can be reduced, time and power consumption required for obtaining the information about the channel can be reduced, and accuracy of the information about the channel can be improved.
