Problems solved by technology

[0004] In the fifth-generation mobile communication system, a scenario that needs to be studied is the reliable transmission of data in the narrowband Internet of Things in the TDD scenario. The common solution mainly relies on repeated data transmission, which leads to a relatively low spectral efficiency of the system. How to increase the spectral efficiency of the narrowband IoT system is an important problem to be solved urgently in the IoT system

Embodiment 1

[0038] The base station sends the first configuration information and the downlink channel state information reference signal CSI-RS1 to the terminal located in the geographic location X. The first configuration information includes at least: information about the number of receiving antennas of the base station. If the number of receiving antennas M is greater than or equal to 128, The first configuration information further includes first sounding reference signal resource set information and first sounding reference signal sequence set information. It should be noted that the more receiving antennas, the stronger the ability of the base station to distinguish terminals through spatial information, and the more spatial fingerprint information available, so that the base station can effectively distinguish terminals by acquiring the uplink channel of the terminal, thereby improving The spectral efficiency of the system.

Abstract

The invention provides a data transmission method in a narrowband Internet of Things based on a D2D architecture, and belongs to the field of wireless communication. The method comprises the followingsteps that: a base station sends first configuration information and a downlink channel state information reference signal CSI-RS1 to the terminal located at the geographic position X; The terminal receives the first configuration information; The base station sends second configuration information to the terminal; The terminal receives the second configuration information and sends data according to the second configuration information; And if the transmission fails, the base station broadcasts the relay terminal, and the terminal transmits data to the base station through the relay terminal. The data transmission method has the beneficial effects that the problem of poor spectrum efficiency in the existing narrowband Internet of Things is solved, and the capacity of the narrowband Internet of Things system is improved.
