Description

Information transmission method, device and equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information transmission method, apparatus, and device.
Background
In the existing communication technology and application, in order to improve reliability, the method is often implemented based on a manner similar to a hot backup, that is, a network side device transmits the same data or different codes of the same data to a terminal through multiple paths simultaneously or fixedly within an allowable time delay range; the same data or different codes of the same data may be transmitted to a plurality of terminals via a plurality of paths simultaneously or fixedly within a permissible time delay range.
However, in an actual application scenario, it is risky to rely on only one terminal to ensure reliability, so that two or more terminals are often needed to perform backup, but actually, it is not desirable to adopt a hot backup manner, that is, two or more terminals are allowed to receive and transmit repetitive contents at all times, especially when multiple services coexist, it appears that under normal conditions, the terminal 1 and the terminal 2 are respectively responsible for the service 1 and the service 2, but when the terminal 1 fails, the terminal 2 needs to be responsible for the service 1 and the service 2 at the same time; or conversely, when the terminal 2 fails, the terminal 1 needs to be responsible for both the service 1 and the service 2. Thus, each of the plurality of terminals needs to be able to transmit multiple services within a given delay range or simultaneously to maintain reliability, which in the prior art needs to consume multiple resources to ensure reliability.
How to ensure that the terminals work independently in most of time under the scene, but the terminals can also be used as backups quickly when necessary, and the transmission overhead of the network is reduced becomes a problem to be solved.

As shown in fig. 4, an embodiment of the present invention further provides an information transmission method applied to a terminal, where the method includes:
step 41, a terminal receives a Physical Downlink Control Channel (PDCCH) which is sent by network side equipment and can be identified by at least 2 associated terminals and used for uplink resource scheduling; and/or a Physical Downlink Control Channel (PDCCH) scheduled by downlink resources, wherein the associated terminal comprises a default transmission terminal and a non-default transmission terminal; the related terminal here means that the first terminal and the second terminal with independent IDs have an agreed mutual substitution and/or mutual trust relationship at the network side; the IDs of the first terminal and the second terminal are different, the first terminal can bear all or part of services of the second terminal between the first terminal and the second terminal, and the network side equipment can know the association relationship through preset information or terminal report; when necessary, one terminal can take over the services which are originally responsible by other terminals, and all the services are not interrupted when the individual terminal has problems;
and 42, under a given condition, performing uplink transmission and/or feedback on downlink reception of the downlink resource by a non-default transmission terminal in the associated terminal through the uplink resource scheduled by the PDCCH.
In this embodiment, the default terminal and the non-default terminal are associated terminals, and when the non-default terminal satisfies a given condition at the default transmission terminal, the uplink resource scheduled by the PDCCH may be used to directly perform the service of the default transmission terminal, so that only one resource is consumed while the service is not interrupted, thereby saving the overhead of network transmission. The first terminal may be a default transmission terminal or a non-default transmission terminal, and the second terminal may be a default transmission terminal or a non-default transmission terminal.
Specifically, the transmitted content is data content which is still required to be transmitted by the default transmission terminal in the associated terminals after a given condition occurs, or is data content which is required to be transmitted by the non-default transmission terminal. Therefore, the method can ensure that the service is not interrupted and only consumes one resource, thereby saving the expense of network transmission.
In an optional embodiment of the present invention, when the non-default transmission terminal uses the uplink resource for transmission, the non-default transmission terminal indicates the network side device that the current transmission is the identification information transmitted by the non-default terminal.
The given condition may include: and the non-default transmission terminal determines that the default transmission terminal associated with the non-default transmission terminal fails, or the connection between the network side equipment and the default transmission terminal fails.
Here, it should be noted that the non-default transmission terminal determines that the default transmission terminal associated therewith fails or the connection between the network side device and the default transmission terminal fails, and may determine by detecting a heartbeat packet or directly receive information fed back by the network side device, for example, the non-default transmission terminal detects the heartbeat packet of the default transmission terminal, and determines that the default transmission terminal fails when the heartbeat packet is not detected within a period of time, or may determine by receiving related information sent by the network side device.
Further, the feedback of the downlink reception of the downlink resource scheduled by the PDCCH by the non-default transmission terminal further includes: and the non-default transmission terminal and the default transmission terminal both feed back hybrid automatic repeat acknowledgement (HARQ-ACK) to the network side equipment, or the non-default transmission terminal feeds back the HARQ-ACK to the network side equipment on the channel resource for feeding back the HARQ-ACK by the default transmission terminal when the default transmission terminal fails or the connection between the network side equipment and the default transmission terminal fails.

Optionally, the channel through which the default transmission terminal feeds back the HARQ-ACK carries information of the default transmission terminal, and the channel through which the non-default transmission terminal feeds back the HARQ-ACK carries information of the non-default transmission terminal.
In an optional embodiment of the present invention, the terminal identifies that the terminal is a default transmission terminal or a non-default transmission terminal for the PDCCH based on the radio network temporary identifier RNTI of the PDCCH.
In this embodiment of the present invention, the terminal receives and detects that the network node sends the PDCCH for uplink resource scheduling that can be identified by at least 2 independent associated terminals, where the independent associated terminals may include, for example, a default transmission terminal and a non-default transmission terminal, which have independent IDs respectively; when the terminal is a default transmission terminal, after the terminal receives the PDCCH, the terminal needs to perform corresponding uplink transmission; and when the terminal is a non-default transmission terminal, if the default transmission terminal is confirmed to be incapable of working normally, the non-default transmission terminal performs uplink transmission according to the dispatching of the PDCCH, otherwise, the non-default transmission terminal does not perform uplink transmission according to the dispatching of the PDCCH. The terminal may identify itself in the associated terminal based on the RNTI of the PDCCH, whether it is the default or non-default transmission terminal for this PDCCH. The related terminal here means that the first terminal and the second terminal with independent IDs have an agreed mutual substitution and/or mutual trust relationship at the network side; a plurality of terminals only consume one resource for each service, and each terminal can be responsible for different services (avoiding competition and multiplexing/collision probability of different service channels or feedback channels in the terminal), and still can ensure the reliability requirement, but when necessary, one terminal can take over the services originally responsible for other terminals, and ensure that all services are not interrupted when problems occur in individual terminals.
