Abstract: The object of the present invention is to provide methods and apparatuses for performing pre-coding. The method includes steps of: upon reception of a reference signal transmitted by eNB, obtaining corresponding cycle indication information by performing a mobility estimation operation, the cycle indication information including cycle order information indicating an order of changing respective wave beams; feeding the cycle indication information back to eNB so that eNB determines, based on the cycle indication information, a cyclic order of the respective wave beams to be changed cyclically. The present invention has the following advantages: UE can perform estimation on its mobility state and feed back to eNB a cyclic order of the respective wave beams to be changed cyclically and information of a change frequency, so that eNB can pre-code information to be transmitted based on the cyclic order and change frequency, thereby obtaining a higher diversity gain and beam-forming gain.
