Embodiment 1

[0051] figure 1 It is a flow chart of an IoT relay confirmation method provided by Embodiment 1 of the present invention. The Internet of Things relay confirmation method provided in the embodiment can be executed by various operating devices used for Internet of Things relay confirmation. The operating device can be implemented by software and / or hardware. The operating device can be two or more It can be composed of a physical entity, or it can be composed of a physical entity.

[0052] The network system used to realize this scheme is such as figure 2 As shown, this network system is applied to a relatively large-scale Internet of Things, and includes a base station 10, a unicast user 20 and multiple multicast users 30 in the network system. Because the distance from the base station 10 is relatively poor, the channel condition is relatively poor; but the multicast users 30 can form clusters and have relatively good channel conditions because the distance from the base s...

Embodiment 2

[0066] image 3 It is a flow chart of an Internet of Things relay confirmation method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the foregoing embodiments.

[0067] Specifically, please refer to image 3 , the Internet of Things relay confirmation method provided in this embodiment specifically includes:

[0068] Step S201: the base station broadcasts a first pilot signal to a unicast user.

[0069] Step S202: the base station broadcasts the first pilot signal to multiple multicast users.

[0070] Step S203: the unicast user calculates a first channel gain in the process of receiving the first pilot signal.

[0071] Step S204: the multicast user calculates a second channel gain in the process of receiving the first pilot signal.

[0072] Step S205: the unicast user broadcasts a second pilot signal to the multicast user, and the second pilot signal carries a different random parameter from the last broadcast of the second ...

Embodiment 3

[0083] Figure 4 It is a schematic structural diagram of an Internet of Things relay confirmation device provided by Embodiment 3 of the present invention. refer to Figure 4 , the IoT relay confirmation device includes: a first broadcast unit 310 , a second broadcast unit 320 , a status confirmation unit 330 and a relay confirmation unit 340 .

[0084] Among them, the first broadcast unit 310 is used for the base station to broadcast the first pilot signal to a unicast user and multiple multicast users; the second broadcast unit 320 is used for the unicast user to broadcast the first pilot signal to the multicast user. Two pilot signals, the second pilot signal carries a random parameter different from the last time the second pilot signal was broadcast; the state confirmation unit 330 is used for the multicast user to use the random parameter according to the random parameter and the preset The random function confirms whether it is a backup multicast user, and the backup ...

Abstract

The embodiment of the invention discloses an Internet of Things relay confirmation method and device, a network system and a storage medium. The method comprises the following steps: a base station broadcasts a first pilot signal to a unicast user and a plurality of multicast users; the unicast user broadcasts a second pilot signal to the multicast users, wherein the second pilot signal carries arandom parameter different from the random parameter when the second pilot signal is broadcasted last time; the multicast users confirm whether the multicast user is a standby multicast user or not according to the random parameter and a preset random function, and the standby multicast user confirms the decoding state of the sending signals of the unicast user and other multicast users accordingto the receiving and sending process of the first pilot signal and the second pilot signal; and the standby multicast user confirms the relay user based on the classification of the decoding state andthe countdown strategy of the corresponding channel gain confirmation. According to the scheme, in some specific user distribution scenes, the multi-user detection and signal transmission effects areimproved, and the overall performance of the network is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technology, and in particular to a method, device, network system and storage medium for relay confirmation of the Internet of Things. Background technique [0002] The Internet of Things (IoT) is regarded as a major opportunity for development and change in the information field, and is expected to bring revolutionary changes. In a more general view, this revolutionary change will be in industry, agriculture, property, City management, safety and fire protection and other fields have a full range of impact. But technically speaking, the Internet of Things not only changes the main body of data transmission, but also has obvious differences from traditional communication. For example, massive IoT is characterized by a large number of users sending very small packets sporadically, unlike traditional cellular communications. [0003] When realizing some industrial-level application...
