The related art to which the present application relates is described below.

In order to achieve high reliability of control signaling, a method for compressing control signaling is considered, such as reducing or shrinking some fields in the control signaling, but the compressible space is limited, so that the reliability of the control signaling is improved to a limited extent.

In view of the above problems, the embodiments of the present application propose the following embodiments, which are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating a reliability transmission method according to an embodiment of the present application, applied to a network device in the exemplary communication system, where the method includes:

in part 201, the network device configures N transmission resources, where N is a positive integer;

wherein N is agreed by a protocol or configured by the network device, for example, the N transmission resources and N may be configured simultaneously through higher layer signaling.

At part 202, the network device sends first configuration information of each transmission resource to a terminal;

wherein the first configuration information is preconfigured by the network device.

At 203, the network device determines a transmission resource and dynamically indicates to the terminal.

It can be seen that, in the embodiment of the present application, a network device first configures N transmission resources, then sends first configuration information of each transmission resource to a terminal, and finally determines one transmission resource and dynamically indicates the transmission resource to the terminal. Therefore, the network device can pre-configure transmission resources at a high layer and dynamically select a scheduling mechanism at a physical layer, so that the dynamic signaling overhead can be reduced, the reliability of scheduling signaling is improved, and the problems of signaling reliability and signaling congestion, especially the problem of the signaling reliability of edge users, are effectively solved. And by combining a service model of a specific service, such as URLLC service, and semi-statically configuring resources, resources can be reasonably allocated and the service transmission requirements can be met. The technology complements dynamic scheduling, can complement advantages and disadvantages, and achieves efficient, high and reliable transmission.

In one possible example, the network device sends, to the terminal, first configuration information of each transmission resource, including: and the network equipment sends the first configuration information of each transmission resource to the terminal through a high-level signaling.

The higher layer signaling may be, for example, radio resource control information RRC, media access control layer control element MAC CE, or the like.

In one possible example, the dynamically indicating, by the network device, to the terminal includes: the network device dynamically indicates to the terminal through user-specific signaling or through user group-specific signaling.

The user-specific signaling may be, for example, user-specific downlink control information UE specific DCI, and the user Group-specific signaling may be, for example, user Group downlink control information Group common DCI.

The Radio Network Temporary Identifier (RNTI) check code of the user-specific signaling is the same as the RNTI check code of other user-specific signaling, and the RNTI check code comprises a cell radio network temporary identifier (C-RNTI) check code; alternatively, the first and second electrodes may be,

the RNTI check code of the user-specific signaling is a specific RNTI check code, and the specific RNTI check code comprises a Resource indication-RNTI check code;

the specific RNTI check code is the same as or shorter than the C-RNTI check code.

In one possible example, the dynamically indicating, by the network device, to the terminal includes: and the network equipment dynamically indicates the number of the first configuration information of the determined transmission resource to the terminal.

Wherein the number of the first configuration information is used for indicating the first configuration information.

In this possible example, the first configuration information includes at least one of the following information: frequency domain resources, time domain resources, reference signal configuration, modulation and coding strategy MCS level configuration, transmission block size, uplink control information UCI on PUSCH mode of a physical uplink shared channel, repetition times, process number, redundancy version RV, new transmission/retransmission and transmission resource number.

For example, assume that the base station configures 16 transmission resources as shown in table 1.

Table 1. configuration information table of transmission resources

When the resource and modulation and coding strategy MCS level required for transmitting data are close to one configuration in table 1, for example, one data determines that 50 PRBs are required according to traffic and channel conditions, 2 symbols are required, and MCS is 0, the base station dynamically indicates transmission resource 2(0010) to the terminal.

For another example, if one data needs to use 8 PRBs, 2 symbols, and MCS is 4 according to the traffic and channel conditions, the base station dynamically instructs the terminal to transmit resources 12 (1100).

For another example, if one data needs to use 5 PRBs, 2 symbols, and MCS is 4 according to the traffic and the channel condition, the base station allocates a specific resource to the terminal by using the dynamic scheduling method.

Compared with the existing dynamic scheduling mode, the dynamic signaling overhead is reduced, and the reliability of the scheduling signaling is improved. The problems of signaling reliability and signaling congestion are effectively solved, and particularly the problem of the signaling reliability of edge users is solved.

In one possible example, after the network device determines a transmission resource and dynamically indicates to the terminal, the method further includes: and the network equipment dynamically indicates the second configuration information corresponding to the determined transmission resource to the terminal.

In this possible example, the first configuration information includes at least one of: transmitting a frequency domain resource, a time domain resource, a reference signal configuration, an MCS level configuration, a transmission block size and a transmission resource number corresponding to the resource;

the second configuration information includes at least one of: the process number corresponding to the transmission resource, RV, new transmission/retransmission, a downlink allocation indicator DAI, a physical uplink control channel PUCCH resource and a physical downlink shared channel confirm response time sequence PDSCH-ACK Timing.

For example, assume that the base station configures 16 transmission resources as shown in table 2.

Table 2. configuration information table of transmission resources

When the resource and MCS level required for transmitting data are close to one of the configurations in table 2, for example, one data needs to use 50 PRBs, 2 symbols, and MCS ═ 0 according to the traffic and channel conditions, the base station dynamically indicates transmission resource 0(0000), and simultaneously indicates the transmission resource to the terminal together with information such as process number, RV version, new transmission/retransmission, DAI, PUCCH resource, PDSCH-ACK Timing, and the like.

For another example, if one piece of data needs to use 8 PRBs, 2 symbols, and MCS is 4 according to the traffic and channel conditions, the base station dynamically indicates the transmission resource 12(1100), and simultaneously indicates the transmission resource to the terminal together with information such as the process number, RV version, new transmission/retransmission, DAI, PUCCH resource, PDSCH-ACK Timing, and the like.

For another example, if one data needs to use 2 PRBs, 2 symbols, and MCS is 4 according to the traffic and the channel condition, the base station allocates a specific resource to the terminal by using the dynamic scheduling method.

In the embodiment, some configuration with high flexibility, such as information of a process number and the like, adopts dynamic indication, and the scheduling flexibility is improved under the condition that the signaling overhead is not greatly improved.

In this possible example, the first configuration information includes at least one of: frequency domain resources, time domain resources and transmission resource numbers corresponding to the transmission resources;

the second configuration information includes at least one of: reference signal configuration corresponding to transmission resources, MCS level configuration, transport block size, process number, redundancy version RV, new transmission/retransmission, DAI, PUCCH resources, and PDSCH-ACK Timing.

In this possible example, the first configuration information includes at least one of: transmitting the frequency domain resource corresponding to the resource, and transmitting the resource number;

the second configuration information includes at least one of: time domain resources corresponding to transmission resources, reference signal configuration, MCS level configuration, transport block size, process number, redundancy version RV, new transmission/retransmission, DAI, PUCCH resources, and PDSCH-ACK Timing.

In one possible example, after the network device determines a transmission resource and dynamically indicates to the terminal, the method further includes: and the network equipment acquires second configuration information corresponding to the determined transmission resource in a protocol convention or implicit mode.

In this possible example, the first configuration information includes at least one of: frequency domain resources, time domain resources, reference signal configuration, MCS level configuration, transmission block size, RV and transmission resource numbers corresponding to the transmission resources;

the second configuration information includes at least one of: the process number corresponding to the transmission resource, new transmission/retransmission, DAI, PUCCH resource, and PDSCH-ACK Timing.

The process number is determined by the time domain resource, the new transmission/retransmission is determined by the RV, the ADI is configured by a specific value at a high layer, or most typically, the HARQ-ACK Multiplexing is not supported by the URLLC, the DAI has no physical significance, or the DAI defaults to 1, the PUCCH resource is obtained by calculation of a high-layer configuration or control resource unit CCE, and the PDSCH-ACK Timing is obtained by high-layer configuration.

For example, assume that the base station configures 16 transmission resources as shown in table 3.

Table 3. configuration information table of transmission resources

When the resource and MCS level required for transmitting data are close to one configuration in table 3, for example, one data needs to adopt 50 PRBs and 2 symbols according to the traffic and channel conditions, and MCS is 0, the base station dynamically indicates transmission resource 0(0000), and meanwhile, the terminal can calculate and obtain a process number based on the time domain position, determine new transmission/retransmission based on the RV version, for example, new transmission corresponds to RV0, retransmission corresponds to RV3, PUCCH resource is calculated and obtained based on the higher layer configuration or CCE, and obtain PDSCH-ACK Timing based on the higher layer configuration.

Some configurations with high flexibility are obtained through a recessive mode or other ways, so that the flexibility of scheduling is improved under the condition that the signaling overhead is not greatly improved, and the flexibility of compressing signaling is still maintained.

In one possible example, after the network device determines a transmission resource and dynamically indicates to the terminal, the method further includes: the network equipment dynamically indicates the second configuration information corresponding to the determined transmission resource to the terminal; and the network equipment acquires the third configuration information corresponding to the determined transmission resource in a protocol convention or implicit mode.
