Embodiment Construction

[0117] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0118] Currently, there is no spectrum scheme in the LoRa specification specifying how LoRa works at 800MHz. In the 800MHz frequency band, 821-824MHz is divided into uplink channels, and 866-869MHz is divided into downlink channels.

[0119] One of the core ideas of the embodiment of the present application is that, in the 800MHz frequency band, setting the uplink and downlink channels can support two different channel frequency widths at the same time, and specify how the terminal uses the two channel frequency widths for uplink and downlink communication.

[0120] The two channel frequency widths can be set according to the communication protocol used by the terminal (for example, LoRa protocol, NB-IoT...

Abstract

The embodiment of the invention provides a method and device for communication between a terminal and a base station and between the terminal and a server, and the method comprises the steps that the terminal sends a first message to at least one first base station through a first uplink channel, wherein the first message is used for requesting to access a network; the terminal receives a second message from the second base station through the first downlink channel, wherein the second message comprises a channel mask, the channel mask is used for indicating the availability of the first uplink channel subset or the first downlink channel subset; the terminal sends data to at least one first base station through the second uplink channel, or receives data from the third base station through the second downlink channel. In the 800MHz frequency band, the terminal can select uplink channels or downlink channels with different frequency widths to perform uplink and downlink communication according to the availability of the first uplink channel subset or the first downlink channel subset.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for communicating between a terminal and a base station, a method for communicating between a terminal and a server, a device for communicating between a terminal and a base station, and a device for communicating between a terminal and a server. Background technique [0002] The Internet of Things technology is the third information technology revolution after computers and the Internet. It has the characteristics of real-time and interactivity, and has been widely used in many fields such as urban management, digital home, positioning and navigation, logistics management, and security systems. Among them, LoRa is an ultra-long-distance transmission scheme based on spread spectrum technology in the Internet of Things, which has the characteristics of long transmission distance, low power consumption, multiple lending points and low cost.
