<p>Disclosed are a method, an apparatus, and a terminal device for transmitting a downlink signal, which can increase the number of resources for transmitting a channel state information-reference signal (CSI-RS), without affecting the system performance. The method comprises: reserving a resource element (RE) in REs for transmitting a downlink Demodulation Reference Signal (DM-RS); and transmitting a CSI-RS on the reserved RE or on the reserved RE and the RE for transmitting downlink data.</p> |
