In an embodiment of the present disclosure, there is provided a method for downlink data transmission in a wireless communication system which comprises transmitting an indication for a new-type reference signal to a user equipment, wherein the new-type reference signal has an identical location in frequency domain to a legacy reference signal; and transmitting the new-type reference signal and the legacy reference signal to the user equipment for using in channel estimation. In a case of more than one antenna port, the new-type reference signal may be designed to have a different location in time domain from a legacy reference signal to avoid interference to other antenna ports. With embodiments of the present disclosure, it is possible to perform a channel estimation based on both the legacy reference signal and the new-type reference signal to achieve a higher accuracy of channel estimation, and thus a UE with a low SNR may be also used in LTE networks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatuses for data transmission in a wireless communication system","description":"Embodiments of the present disclosure relate to downlink/uplink data transmission in a wireless communication system.
