摘要：
Feedback methods and apparatuses are provided for efficiently feeding back downlink Channel State Information (CSI) using limited information in a DAS-based wireless communication system. A method includes determining, by a receiver, a candidate Antenna Port (AP) set from among a plurality of APs; selecting an active AP set from the candidate AP set; and transmitting the candidate AP set, the active AP set, and the downlink CSI of active APs included in the active AP set
