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

Abstract

The embodiment of the invention discloses a frequency hopping communication method and equipment thereof, which are used for determining a physical channel for frequency hopping in a narrowband system of an unlicensed spectrum. The method in the embodiment of the present invention includes: the terminal device receives a plurality of virtual channel index numbers from the base station; the terminal device selects a virtual channel index number from the plurality of virtual channel index numbers; the terminal device selects a virtual channel index number according to the virtual channel index number; The number determines the physical channel corresponding to the virtual channel index number on multiple subframes, and the virtual channel index number is different in at least two physical channels among the physical channels of the multiple subframes; the terminal device is in the The physical channel corresponding to the virtual channel index number is used to communicate with the base station in at least one subframe among the plurality of subframes.

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...
