Title:
狭帯域モノのインターネット（ＮＢ－ＩｏＴ）のためのデータ送信スキームのための方法および装置
Document Type and Number:
Japanese Patent JP7094883
Kind Code:
B2
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for implementing a data transmission scheme for Narrow-Band Internet of Things (NB-IoT). A User Equipment (UE) combines pairs of antenna ports to generate at least first and second combined antennas ports. The UE receives reference signals transmitted in a narrow band region of a larger system bandwidth, and for each combined port, adds the references signals received on resource elements (REs) of each of the combined pair of antenna ports. The UE determines channel estimates for each combined antenna port based on the added reference signals for the combined port.
