Abstract

The invention provides a narrowband Internet of Things uplink data transmission method and a base station. The method comprises the following steps of: if it is judged that the number of times of receiving the first target data within the preset time is greater than or equal to 1, issuing a second retransmission frequency indication to the terminal, so that the terminal sends second target data according to a second retransmission frequency indicated by the second retransmission frequency indication during next data transmission, and the second retransmission frequency is less than or equal tothe first retransmission frequency. According to the narrowband Internet of Things uplink data transmission method and the base station provided by the invention, the retransmission times when the terminal uploads the data are adjusted according to the situation that the base station receives the data in the data uploading process of the terminal, so that the data uploading efficiency of the terminal is improved, the cell capacity is improved, and the network performance of the narrowband Internet of Things is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a narrowband Internet of Things uplink data transmission method and a base station. Background technique [0002] Narrowband Internet of Things (NB-IoT) mainly supports services that are not sensitive to delay, have no minimum rate requirements, and have large transmission intervals and low transmission frequencies. [0003] In the prior art, in order to achieve coverage extension (Coverage Enhancement, CE) to meet the needs of terminals deployed at the edge of the cell or with low channel quality, in the uplink, the terminal repeatedly sends uplink data to reduce the cost of sending data by the terminal. BER. Among them, the number of repeated transmissions of uplink data of the terminal is determined by the base station according to the CE level of the terminal, and the DCI format N0 information in the narrowband physical downlink control channel NPDCCH indica...
