Embodiment 1

[0043] The base station sends the first configuration information and the downlink channel state information reference signal CSI-RS1 to the terminal located at the geographic location X, the first configuration information includes at least: the number of receiving antennas of the base station, if the number M of receiving antennas is greater than or equal to 128, Then the first configuration information further includes first SRS resource set information and first SRS sequence set information. It should be noted that the more the number of receiving antennas, the stronger the ability of the base station to distinguish terminals through spatial information, and the more spatial fingerprint information is available. In this way, the base station can effectively distinguish terminals only by obtaining 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 beam sensing, and belongs to the field of wireless communication. The method comprises the following stepsthat: a base station sends first configuration information and a downlink channel state information reference signal CSI-RS1 to a terminal located at the geographic position X; the terminal receivesthe 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 thesecond configuration information; if the transmission fails, the base station transmits beam configuration information and beams; and if the terminal successfully senses the beam, the base station activates the relay node in the sensed beam coverage range, and the terminal sends data to the base station through the relay node. 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.
