Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment
Referring to fig. 1, fig. 1 is a flowchart illustrating a robust data processing method for internet of things according to a first embodiment of the present invention.
As shown in fig. 1, in this embodiment, the robust internet of things data processing method includes the following steps:
s102, in a node set including N terminals (second communication nodes), there is a master terminal (master second communication node) and (N-1) slave terminals (slave second communication nodes), where the master terminal sends a first request message to a base station (first communication node) and requests the base station to send a channel state indication information reference signal, where N is an integer greater than 3, the electric quantity of the slave terminal is greater than or equal to 70% of the maximum available electric quantity, and the slave terminal does not perform service data communication with the base station within the previous 10 seconds.
The reason for this is that the future service demand of the slave terminal is predicted to be smaller by analyzing the data transmission behavior and the available electric quantity of the slave terminal, so that the master control terminal is helped to receive data, and the service of the slave terminal is not influenced.
And S104, after receiving the first request message, the base station sends a channel state indication message reference signal to the node set.
The purpose of this is that the terminals in the node set can measure the downlink channel state information between the base station and itself based on the reference signal.
S106, the N terminals measure and obtain channel state information between the base station and the N terminals based on the channel state indication information reference signals, the main control terminal broadcasts the channel state information of the main control terminal to the (N-1) slave terminals, the (N-1) slave terminals obtain channel correlation information through inner product operation based on the channel state information of the main control terminal and the channel state information of the slave terminals, and each slave terminal sends the channel correlation information obtained through calculation to the main control terminal.
The purpose of this is that the main control terminal determines the terminal composition of the subsequent terminal group by collecting these channel state information.
And S108, the main control terminal receives the (N-1) channel correlation information and forms a first service type terminal group, a second service type terminal group and a third service type terminal group based on the channel correlation information.
The first service type terminal group at least comprises a main control terminal and a subordinate terminal with the lowest channel correlation with the main control terminal, so that the first service type is a low-delay high-reliability service, the multiple channels with the lowest correlation are used for repeated transmission of the same data, the diversity characteristic of the channels can be fully utilized to improve the probability of successful data transmission, and the requirements of the services can be better met under the condition that a small number of terminals participate in complex decoding.
The second service type terminal group at least comprises a main control terminal and a subordinate terminal with lowest channel correlation and second lowest channel correlation with the main control terminal. The advantage of this is that the second type of service is a mobile broadband service, which has a high requirement on the spectral efficiency of the system, and the service multiplexing transmission is realized by fully utilizing the orthogonal property of the channel, so as to improve the utilization efficiency of the spectral resources and meet the transmission requirement of the service under the condition that as few terminals as possible participate in the complex decoding.
The third service type terminal group comprises a main control terminal and (N-1) slave terminals, and the reason for doing so is that the third service type is machine type communication, the transmission data volume is small, the decoding complexity is not high, more terminals can be used for decoding operation, and therefore the service quality of the services is improved.
And the main control terminal informs the group information of the first service type terminal group, the second service type terminal group and the third service type terminal group to (N-1) slave terminals.
S110, the main control terminal generates uniform channel state information of the first service type terminal group based on the channel state information of all the terminals in the first service type terminal group; the main control terminal generates unified channel state information of the second service type terminal group based on the channel state information of all the terminals in the second service type terminal group; the master control terminal generates uniform channel state information of the third service type terminal group based on the channel state information of all the terminals in the third service type terminal group; and the main control terminal feeds back the channel state information of the first service type terminal group, the channel state information of the second service type terminal group and the channel state information of the third service type terminal group to the base station.
The advantage of this is that the main control terminal feeds back various types of channel state information to the base station, and the base station can select proper channel state information to generate downlink control information to guide the terminal to receive data according to the service transmission requirement.
S112, the base station determines the service type of the data sent to the main control terminal, and if the service type is the first service type, the base station sends the data to the first service type terminal group according to the channel state information of the first service type terminal group; if the terminal group is the second service type, the first communication sends data to the second service type terminal group according to the channel state information of the second service type terminal group; and if the service type is the third service type, the base station sends data to the third service type terminal group according to the channel state information of the third service type terminal group.
And S114, if the main control terminal sends the receiving failure information to the base station and the service type of the data is the first service type, the base station retransmits the data and requires the main control terminal and the (N-1) slave terminals to receive the data.
The reason for this is that the probability of successful decoding of the retransmitted data is improved by adding a plurality of terminals to perform complex decoding operation, and the transmission requirement of a low-delay and high-reliability service is met as much as possible.

The advantage of this is that when the number of terminals in the node set is large, the power between the terminals is supplemented by other means, so that a plurality of terminals can participate in the data transmission of the first service type and the second service type as much as possible, thereby improving the service quality of the two service types.
Fifth embodiment
