摘要：
A method for indicating precoding information, user equipment (UE) and an access network entity are provided according to the disclosure. The method includes: receiving, by a user equipment (UE), a control signaling transmitted by an access network entity; determining, by the UE, a multilevel codebook index in response to the control signaling; and determining, by the UE, a target precoding matrix based on the multilevel codebook index and a multilevel codebook obtained in advance.
