Problems solved by technology

However, in the Class C mode, due to the unpredictability of the arrival of downlink data in the second receiving time window (RX2Window), the relay device may relay business with other terminals or Collision of own data business
In addition, the relay device must open the receiving window for a long time to prepare to receive Class C downlink data frames, which hinders the relay device from receiving the terminal's uplink data frames, thereby reducing network transmission efficiency

Abstract

The embodiment of the invention provides a communication method and device based on relay equipment and a communication method and device of a terminal and a base station. The communication method based on the relay equipment comprises the steps that the relay equipment receives a first uplink data frame sent by the terminal, wherein the first uplink data frame comprises a first mode identifier and a terminal identifier, and the first mode identifier is used for enabling the base station to consider that the terminal operates in a first mode; the relay equipment records the operation mode of the terminal as a second mode according to a first information set and the terminal identifier; the relay equipment sends the first uplink data frame to the base station; the relay equipment receives afirst downlink data frame sent by the base station; and the relay equipment sends the first downlink data frame to the terminal. In the embodiment of the invention, the first uplink data frame comprises the first mode identifier, so that the base station sends the first downlink data frame in the appointed time window, and the unpredictability of sending the first downlink data frame is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a communication method based on a relay device, a communication method between a terminal and a base station, a communication device based on a relay device, and a communication device between a terminal and a base station. Background technique [0002] The Internet of Things technology is the third information technology revolution after computers and the Internet. It has the advantages 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, multi-node and low cost. [0003] In the existing data transmission method, the LoR...
