Frequency hopping communication method and device thereof

Abstract

The embodiment of the invention discloses a frequency hopping communication method and a device thereof for determining a physical channel for frequency hopping in a narrowband system of an unlicensedspectrum. The method disclosed by the embodiment of the invention comprises the following steps: a terminal device receives a plurality of virtual channel index numbers from a base station; the terminal device selects a virtual channel index number from the plurality of virtual channel index numbers; the terminal device determines physical channels corresponding to the virtual channel index number on a plurality of sub-frames according to the virtual channel index number, wherein the virtual channel index number is in the physical channels of the plurality of sub-frames, and at least two physical channels are different from each other; and the terminal device communicates with the base station on at least one sub-frame of the plurality of sub-frames by using the physical channels corresponding to the virtual channel index number.

Description

technical field [0001] The present invention relates to the communication field, in particular to a frequency hopping communication method and equipment thereof. Background technique [0002] With the rapid development of the mobile Internet and the Internet of Things industry, Internet of Things network devices are characterized by low cost, easy deployment, and maintenance-free. In the enterprise market, the communication requirements of the enterprise IoT are concentrated on small data volumes and massive connections. Compared with the licensed spectrum of operators, the unlicensed spectrum, especially the SubG Hz frequency band, can effectively reduce network costs. Therefore, based on unlicensed spectrum Narrowband communication systems can meet this need. [0003] On the unlicensed spectrum, all countries and regions have corresponding regulations on the unlicensed spectrum, which prevents all devices from sending irregularly and unrestrictedly on the unlicensed spect...

Problems solved by technology

[0005] However, because Bluetooth uses time division multiple access technology, when a central device needs to communicate with multiple slave devices, at a point in time, it cannot communicate with multiple slave devices, so a Bluetooth master device cannot connect too many slave devices at the same time , thus unable to meet the needs of the Internet of Things with massive connections
