METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA

摘要

A transmission scheme newly adds a Demodulation Reference Signal (DM-RS) to estimate a channel response for demodulation. When a transmission scheme based on Long Term Evolution Common Reference Signal (LTE CRS) is set in a user, a corresponding user cannot receive data in a Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) sub-frame. To solve this problem, the present scheme separates and sets a transmission mode for sub-frame and a transmission mode for MBSFN.
