The invention belongs to the field of communication technology, and particularly relates to a method, equipment and computer storage medium for sending and receiving auxiliary indication signaling.

In the fifth-generation mobile communication system (5G), enhanced mobile broadband (eMBB) and applications have high latency tolerance and low reliability requirements, while low-latency and highly reliable communications (Ultra-Reliable and Low Latency Communications, URLLC), the application requires extremely low latency and high reliability, and has the characteristics of burstiness, so the priority of URLLC application can be set higher than that of eMBB application; when eMBB application is scheduled on the network side Later, if a URLLC application scheduling request is received from the terminal or when the URLLC application sends data on a resource location that overlaps with the eMBB application, in order to reduce the interference caused by the eMBB application channel to the URLLC application channel, and avoid causing the URLLC performance Declining, the possible solutions proposed at this stage include canceling the sending of eMBB data through the information carried by the downlink control channel, dynamically adjusting the transmission power of the URLLC application channel, and switching the resource location of the URLLC application (Grant-free).

Further, there are many applications with different priorities in the current communication system. When the network side schedules applications with low priority and needs to schedule applications with higher priority on the resources already occupied by the low priority, it is necessary to use Certain measures are taken to reduce the interference of low-priority applications to high-priority applications, such as notifying the terminal to cancel low-priority applications, or Suspend low-priority applications, or increase the transmission power of high-priority applications.

In specific implementation, when sending instructions to notify the terminal to cancel low-priority applications, or suspend the sending of low-priority applications, methods such as indicating the cancellation of low-priority application channel transmission through display indication signaling will bring additional resource consumption and terminal complexity The promotion. For example, the terminal needs to monitor more physical downlink control channels (PDCCH), which causes more blind detection and channel estimation complexity. In addition, for the sequence-based scheme, since the reference signal needs to occupy periodic resources for transmission, these exclusive resources will seriously consume the total number of available resources in the system, thereby reducing system performance.

Therefore, in the prior art, when sending instructions to process low-priority applications that partially overlap with high-priority application resources, signaling consumption is large.

The present invention provides a method, equipment and computer storage medium for sending and receiving auxiliary indication signaling, which is used to solve the problem of high signaling consumption when sending instructions to process low-priority applications that partially overlap with high-priority application resources in the prior art The problem.

Each will be described below.

1. Transmission of auxiliary indication signaling through the downlink control channel.

In the specific implementation process, first, after the network side device sends the scheduling information of the low-priority application data channel to the terminal, it implicitly determines the location of the candidate resource for sending the auxiliary indication signaling.

In specific implementation, the network side device implicitly determines that the candidate resource location for sending the auxiliary indication signaling is the downlink control channel resource in the time domain interval.

According to the manner in which the network-side device determines the candidate resource location of the auxiliary indication signaling, there are three situations in which the candidate resource location for sending the auxiliary indication signaling is determined.

Case 1: The network side device determines the starting position of the candidate resource location for sending the auxiliary indication signaling according to the time when it sends the scheduling information of the low-priority application data channel and the preset first time interval.

Correspondingly, the terminal applies the scheduling information of the data channel according to the received low priority order. The time of communication and the preset first time interval determine the starting position point of the candidate resource position for detecting auxiliary indication signaling.

As shown in Figure 3, in this case, when the network-side device instructs the terminal to process the low-priority application data channel through auxiliary indication signaling, the network-side device can send the scheduling information of the low-priority application data channel to the terminal After that, it starts timing until it reaches the preset first time interval, and sends auxiliary indication signaling to the terminal. At the same time, after receiving the scheduling information of the low-priority application data channel, the terminal also starts timing until it reaches the preset first time interval. After the time interval, start to detect auxiliary indication signaling at the candidate resource location. In this way, the terminal does not need to monitor the physical downlink control channel in this time domain resource in the first time interval after the scheduling information of the low-priority application data channel is sent, so the number of physical downlink control channels that the terminal needs to detect is reduced, thereby reducing The complexity of blind detection and channel estimation, and at the same time, implicitly determine the location of candidate resources for the terminal to detect auxiliary indication signaling, which reduces signaling expenditure and saves system performance.

Case 2: The network side device uses the start time domain position of the data channel and the preset second time interval according to any priority order to determine the end position of the candidate resource position for sending the auxiliary indication signaling; accordingly, the terminal according to any A priority sequence applies the start time domain position of the data channel and the preset second time interval to determine the end position point of the candidate resource position for detecting the auxiliary indication signaling.

As shown in Figure 4, in this case, when the network side device instructs the terminal to process the low-priority application data channel through the auxiliary indication signaling, it can select a priority application from all the priority applications, and use this priority order Using the start time domain position of the data channel as the reference, the preset second time interval is forwarded to determine the end position of the candidate resource position for sending the auxiliary indication signaling, and the terminal determines the detection auxiliary indication signaling in the same way Waiting Select the end point of the resource location. In this way, after receiving the scheduling information of the low-priority application data channel, the terminal starts to detect the auxiliary indication signaling, and stops detecting the auxiliary indication signaling when the termination point is reached. Therefore, the number of physical downlink control channels monitored by the terminal is reduced, thereby reducing the complexity of blind detection and channel estimation. At the same time, the candidate resource position of the terminal detection auxiliary indication signaling is determined implicitly, which reduces signaling expenditure and saves system performance .

Case 3: The network side device determines the starting position of the candidate resource location for sending the auxiliary indication signaling according to the time when it sends the scheduling information of the low-priority application data channel and the preset first time interval; and according to any one The priority sequence uses the start time domain position of the data channel and the preset second time interval to determine the end position point of the candidate resource position for sending the auxiliary indication signaling.

Correspondingly, the terminal determines the starting position of the candidate resource position for detecting the auxiliary indication signaling according to the time when the scheduling information of the low-priority application data channel is received and the preset first time interval; and according to any priority order The start time domain position of the data channel and the preset second time interval are used to determine the end position point of the candidate resource position for detecting the auxiliary indication signaling.

As shown in Figure 5, in this case, when the network side device instructs the terminal to process the low-priority application data channel through the auxiliary indication signaling, it determines the starting point for sending the auxiliary indication signaling while also determining Correspondingly, the terminal determines the starting position point of the candidate position for detecting the auxiliary indication signaling, and also determines the termination point of the candidate position for detecting the auxiliary indication signaling. Location point. Compared with case 1 and case 2, case 3 further narrows the candidate resource positions of terminal auxiliary indication signaling, reduces the number of physical downlink control channels monitored by the terminal, and reduces blind detection and channel estimation. At the same time, the location of candidate resources for the terminal to detect auxiliary indication signaling is determined implicitly, which reduces signaling expenditure and saves system performance.

The above-mentioned preset first time interval may be configured by the network side device, or implicitly determined according to the capability of the terminal, or pre-defined through a protocol.

Subsequently, after the network side device determines the location of the candidate resource for sending the auxiliary indication signaling, it will send the auxiliary indication signaling to the terminal instructing the terminal to process the low-priority application data channel; accordingly, the terminal displays the corresponding auxiliary indication signal Detect and receive auxiliary indication signaling at the position of the candidate resource of the command.

Optionally, the network side device determines the aggregation level used for sending the auxiliary indication signaling at the candidate resource location according to the aggregation level used by the scheduling information of the low-priority application channel; and based on the determined aggregation level in the candidate resource The location sends the auxiliary indication signaling to the terminal; accordingly, the terminal determines the aggregation level used to receive the auxiliary indication signaling at the candidate resource location according to the aggregation level used by the received scheduling information of the low priority application data channel ; And according to the determined aggregation level to detect the auxiliary indication signaling at the candidate resource location.

Wherein, the aggregation level used by the auxiliary indication signaling is greater than or equal to the aggregation level used by the scheduling information.

In the above method, the network side equipment and the terminal determine the aggregation level corresponding to the auxiliary indication signaling according to the aggregation level used by the scheduling information of the data channel in the low priority order, and complete the auxiliary indication signaling according to the aggregation level corresponding to the determined auxiliary indication signaling Transmission and reception, and ensure that the aggregation level used by the auxiliary indication signaling is greater than or equal to the aggregation level used by the scheduling information He level. In this way, after the aggregation level used by the scheduling information of the low-priority application data channel is determined, the aggregation level corresponding to the auxiliary indication signaling can be greater than or equal to the aggregation level used by the scheduling information, so as to improve the terminal detection auxiliary indication signal. The successful rate of blind detection of the order further reduces the number of blind detection of the terminal and reduces the complexity of the terminal side.

Wherein, the aggregation level indicates the number of continuous control channel elements (control channel elements, CCEs) occupied by a PDCCH. The larger the number of CCEs actually allocated by the network side device to the terminal, the higher the success rate of blind detection.

In specific implementation, when the auxiliary indication signaling is carried on the downlink control channel, the auxiliary search space can be configured with multiple aggregation levels.

For example, aggregation level {1, 2, 4, 8, 16}, eMBB application is a low priority application, base station and terminal can refer to the corresponding PDCCH aggregation level used by scheduling eMBB application to determine the auxiliary search in the candidate resource location The aggregation level used by the auxiliary indication signaling sent in the space.

Assuming that the base station uses the aggregation level AL=2 when scheduling the physical uplink shared channel (PUSCH) of the eMBB entity, when sending the auxiliary indication information in the auxiliary search space of the candidate resource location, the following strategy can be used to determine the aggregation grade.

1. Use the same aggregation level as the eMBB scheduling PDCCH.

The aggregation level used when the network side device sends the scheduling information of the eMBB application data channel to the terminal is the aggregation level corresponding to the auxiliary indication signaling when the network side device sends the auxiliary indication signaling to the terminal.

2. Determine the aggregation level used by the auxiliary indication information according to a certain offset; set the offset to 1, then the aggregation level used by the auxiliary indication information AL _auxiliary =AL _scheduling +1, and the maximum usable aggregation level is AL=16; then When the network side device sends the scheduling information of the eMBB application data channel to the terminal, the aggregation level used is 4, then the network side device sends the auxiliary indication signaling to the 8 aggregation level.

3. The corresponding relationship between the aggregation level used by the scheduling information of the low priority application data channel and the aggregation level used by the auxiliary indication signaling can be preset, and then the scheduling information of the data channel can be applied according to the determined low priority order The used aggregation level determines the aggregation level used by the terminal and the network side equipment to receive and send the auxiliary indication signaling.

For example: The following table shows the correspondence between the aggregation level used by the scheduling information of the low-priority application data channel and the aggregation level used by the auxiliary indication signaling:

當確定網路側設備發送eMBB應用資料通道的調度資訊所使用的聚合等級為4時，由上表可知，網路側設備發送輔助指示信令所使用的聚合等級為8，網路側設備與終端確定發送和檢測輔助指示信令時所使用的聚合等級為8。

When it is determined that the aggregation level used by the network-side equipment to send the scheduling information of the eMBB application data channel is 4, the above table shows that the aggregation level used by the network-side equipment to send auxiliary indication signaling is 8, and the network-side equipment and the terminal confirm to send The aggregation level used when detecting auxiliary indication signaling is 8.

It should be noted that in the specific implementation of the embodiments of the present invention, the three solutions for determining the location of candidate resources for sending and detecting auxiliary indication signaling and determining the aggregation level corresponding to the auxiliary indication signaling can be used in combination. Better reduce system resource consumption.

Further, the terminal detects at the determined candidate resource position of the auxiliary indication signaling After the auxiliary indication signaling is received, the low priority application data channel will be processed according to the received auxiliary indication signaling to reduce the transmission of the low priority application data channel to the high priority application data channel that overlaps with its resources. Signal interference.

Optionally, the auxiliary indication signaling includes one of the following functions: instructing to reschedule low-priority application data transmission; instructing low-priority application data channel cancellation; instructing low-priority application data channel suspension; instructing low-priority application data The channel reduces the transmit power.

In specific implementation, the auxiliary indication information detected by the terminal will carry one of the above-mentioned functions; when the auxiliary indication signaling includes signaling for instructing the rescheduling of low-priority application data transmission, when the network side has scheduled the low-priority application Later, when it is necessary to schedule high-priority application data channels on resources that overlap with low-priority application data channels, the network-side device sends auxiliary instruction signaling that includes instructions to reschedule low-priority application data transmission functions to the terminal to indicate The terminal re-schedules resources for low-priority application data transmission; when the auxiliary indication signaling includes signaling indicating that the low-priority application data channel is cancelled, after the network side has scheduled the low-priority application, it needs to be When scheduling high-priority application data channels on resources with overlapping priority application data channels, the network side device sends auxiliary instruction signaling containing the function of canceling the low-priority application data channel to the terminal to instruct the terminal to cancel the low-priority application data The resources configured by the channel overlap with the high-priority application data channel, that is, the terminal is instructed to release the resources occupied by the low-priority application data channel for transmission by the high-priority application; when the auxiliary indication signaling includes the indication of low priority When the signaling of data channel pause is applied When the network side has scheduled low-priority applications, it is necessary to schedule high-priority application data channels on resources that overlap with the low-priority application data channels, the network-side equipment will include an auxiliary instructing the low-priority application data channel to suspend function Instruction signaling is sent to the terminal, instructing the terminal to suspend the transmission of low-priority application data on the resources shared by the low-priority application data channel and the high-priority application data channel, prioritize the high-priority application data transmission after the completion of the low priority Sequence application data transmission; when the auxiliary indication signaling includes signaling that instructs the low-priority application data channel to reduce the transmission power, after the network side has scheduled the low-priority application, it is necessary to use the data channel in the low-priority order When scheduling high-priority application data channels on overlapping resources, the network side device sends auxiliary indication signaling including the pause function of the low-priority application data channel to the terminal, instructing the terminal to apply the data channel and high-priority application in the low-priority order The resources shared by the data channels reduce the transmission power of low-priority application data transmission, and reduce the interference of low-priority application data channel transmission to high-priority application data channel transmission.

2. The auxiliary indication signaling is transmitted through the reference signal.

In the specific implementation process, first, after the network side device sends the scheduling information of the low-priority application data channel to the terminal, it implicitly determines the location of the candidate resource for sending the auxiliary indication signaling.

In specific implementation, the network-side device implicitly determines that the candidate resource location for sending the auxiliary indication signaling is the reference signal resource in the time domain.

According to the manner in which the network side device determines the candidate resource location of the auxiliary indication signaling, there are three situations in which the candidate resource location for sending the auxiliary indication signaling is determined.

Case 1: The network side device sends the data channel according to its own low priority The time of the scheduling information and the preset first time interval determine the starting position point of the candidate resource position for sending the auxiliary indication signaling.

Correspondingly, the terminal determines the starting position point of the candidate resource position for detecting the auxiliary indication signaling according to the time when the scheduling information of the low-priority application data channel is received and the preset first time interval.

As shown in Figure 3, in this case, when the network-side device instructs the terminal to process the low-priority application data channel through auxiliary indication signaling, the network-side device can send the scheduling information of the low-priority application data channel to the terminal After that, it starts timing until it reaches the preset first time interval, and sends auxiliary indication signaling to the terminal. At the same time, after receiving the scheduling information of the low-priority application data channel, the terminal also starts timing until it reaches the preset first time interval. After the time interval, start to detect auxiliary indication signaling at the candidate resource location. In this way, the terminal does not need to monitor the physical downlink control channel in this time domain resource in the first time interval after the scheduling information of the low-priority application data channel is sent, so the number of physical downlink control channels that the terminal needs to detect is reduced, thereby reducing The complexity of blind detection and channel estimation, and at the same time, implicitly determine the location of candidate resources for the terminal to detect auxiliary indication signaling, which reduces signaling expenditure and saves system performance.

Case 2: The network side device uses the start time domain position of the data channel and the preset second time interval according to any priority order to determine the end position of the candidate resource position for sending the auxiliary indication signaling; accordingly, the terminal according to any A priority sequence applies the start time domain position of the data channel and the preset second time interval to determine the end position point of the candidate resource position for detecting the auxiliary indication signaling.

As shown in Figure 4, in this case, when the network-side device instructs the terminal to process the low-priority application data channel through auxiliary indication signaling, it can respond from all priority orders. A priority application is selected from the application, and the starting time domain position of the application data channel in the priority order is used as a reference, and the preset second time interval is forwarded to determine the end position of the candidate resource position for sending auxiliary indication signaling. At the same time, the terminal determines the termination location point of the candidate resource location for detecting auxiliary indication signaling in the same manner. In this way, after receiving the scheduling information of the low-priority application data channel, the terminal starts to detect the auxiliary indication signaling, and stops detecting the auxiliary indication signaling when the termination point is reached. Therefore, the number of physical downlink control channels monitored by the terminal is reduced, thereby reducing the complexity of blind detection and channel estimation. At the same time, the candidate resource position of the terminal detection auxiliary indication signaling is determined implicitly, which reduces signaling expenditure and saves system performance .

Case 3: The network side device determines the starting position of the candidate resource location for sending the auxiliary indication signaling according to the time when it sends the scheduling information of the low-priority application data channel and the preset first time interval; and according to any one The priority sequence uses the start time domain position of the data channel and the preset second time interval to determine the end position point of the candidate resource position for sending the auxiliary indication signaling.

Correspondingly, the terminal determines the starting position of the candidate resource position for detecting the auxiliary indication signaling according to the time when the scheduling information of the low-priority application data channel is received and the preset first time interval; and according to any priority order The start time domain position of the data channel and the preset second time interval are used to determine the end position point of the candidate resource position for detecting the auxiliary indication signaling.

As shown in Figure 5, in this case, when the network side device instructs the terminal to process the low-priority application data channel through the auxiliary indication signaling, it determines the starting point for sending the auxiliary indication signaling while also determining Corresponding to the end position point for sending the auxiliary indication signaling. Correspondingly, the terminal is at the same time as the starting position point of the candidate position for detecting auxiliary indication signaling. The end point of the candidate position for detecting auxiliary indication signaling is also determined. Compared with case 1 and case 2, case 3 further narrows the candidate resource positions of terminal auxiliary indication signaling, reduces the number of physical downlink control channels monitored by the terminal, and reduces the complexity of blind detection and channel estimation At the same time, the candidate resource location for the terminal to detect auxiliary indication signaling is determined implicitly, which reduces signaling expenditure and saves system performance.

Wherein, the above-mentioned preset first time interval may be configured by the network side device, or it may be implicitly determined according to the capability of the terminal, or may be predefined through a protocol.

After determining the location of the candidate resource for sending the auxiliary indication signaling, the network side device will then send the auxiliary indication signaling to the terminal instructing the terminal to process the low-priority application data channel; accordingly, the terminal sends the auxiliary indication signaling in the corresponding auxiliary indication signaling Detect and receive auxiliary indication signaling at the candidate resource location.

Since the auxiliary indication signaling is carried on the reference signal, the terminal directly detects the auxiliary indication signaling on the determined candidate resource location.

In specific implementation, after the terminal detects the auxiliary indication signaling at the determined candidate resource location of the auxiliary indication signaling, it will process the low-priority application data channel according to the received auxiliary indication signaling to reduce the low-priority order. Application data channel transmission causes signal interference to high priority application data channels that overlap with its resources.

Optionally, the auxiliary indication signaling includes one of the following functions: instructing to reschedule low-priority application data transmission; instructing low-priority application data channel cancellation; instructing low-priority application data channel suspension; Instruct the low priority order to apply the data channel to reduce the transmit power.

In specific implementation, the auxiliary indication information detected by the terminal will carry one of the above-mentioned functions; when the auxiliary indication signaling includes signaling for instructing the rescheduling of low-priority application data transmission, when the network side has scheduled the low-priority application Later, when it is necessary to schedule high-priority application data channels on resources that overlap with low-priority application data channels, the network-side device sends auxiliary instruction signaling that includes instructions to reschedule low-priority application data transmission functions to the terminal to indicate The terminal re-schedules resources for low-priority application data transmission; when the auxiliary indication signaling includes signaling indicating that the low-priority application data channel is cancelled, after the network side has scheduled the low-priority application, it needs to be When scheduling high-priority application data channels on resources with overlapping priority application data channels, the network side device sends auxiliary instruction signaling containing the function of canceling the low-priority application data channel to the terminal to instruct the terminal to cancel the low-priority application data The resources configured by the channel overlap with the high-priority application data channel, that is, the terminal is instructed to release the resources occupied by the low-priority application data channel for transmission by the high-priority application; when the auxiliary indication signaling includes the indication of low priority When applying data channel suspension signaling, after the network side has scheduled low-priority applications, it is also necessary to schedule high-priority application data channels on resources that overlap with the low-priority application data channels, and the network-side equipment will include the indication low The auxiliary indication signaling of the priority application data channel suspension function is sent to the terminal to instruct the terminal to suspend the transmission of low priority application data on the resources shared by the low priority application data channel and the high priority application data channel, and give priority to the high priority application After the data transmission is completed, data transmission shall be resumed in the low priority order; when the auxiliary indication signaling includes the instruction to reduce the transmission power of the data channel in the low priority order For signaling, after the network side has scheduled low-priority applications, it also needs to schedule high-priority application data channels on resources that overlap with the low-priority application data channels, and the network-side equipment will include instructions for low-priority application data channels Auxiliary instruction signaling of the pause function is sent to the terminal, instructing the terminal to use the resources shared by the low-priority application data channel and the high-priority application data channel to reduce the transmission power of the low-priority application data transmission, and reduce the low-priority application data channel Transmission interferes with high-priority application data channel transmission.

Among them, the reference signal has a fixed pattern and period. After the network side device and terminal determine the time domain position of the reference signal that needs to send and listen to the bearer auxiliary indication signaling through the above method, they can be the reference signal in the non-detected position Other channels or signal transmissions are scheduled on the reserved resources to improve resource utilization efficiency.

In the following, in the 5G system, after the eMBB application is scheduled, there is also a need to schedule the URLLC application on the resources of the eMBB application as an example.

In the first embodiment, the candidate resource position of the auxiliary indication signaling is the entire auxiliary search space, as shown in FIG. 2.

Assume that two terminals UE1 and UE2 are scheduled on the network side, where UE1 transmits the eMBB application and UE2 transmits the URLLC application. The network side sends an uplink scheduling grant (UL grant) in slot n to schedule UE1 to transmit eMBB PUSCH on slot n+2 (time slot n+2), where the aggregation level used by UE1's eMBB application scheduling information is 4.

The network side enables the auxiliary indication signaling function for UE1 through RRC signaling. The auxiliary indication signaling is sent through the downlink control channel. In this embodiment, the listening period of the auxiliary search space is 2-orthogonal frequency division multiplexing symbol (2 -Orthogonal Frequency Division Multiplexing (OFDM), 2-OS).

The base station can set that all search spaces after sending eMBB application data channel scheduling information can be used as candidate resource locations for auxiliary indication signaling, and do not limit the candidate resource locations for receiving and sending auxiliary indication signaling; and when sending auxiliary indication signaling Set the aggregation level used to send the auxiliary indication signaling to be greater than or equal to the aggregation level used by the scheduling information of the eMBB application. For example, the aggregation level used for the auxiliary indication signaling is 8, so that the terminal detection assistance indication can be improved according to the method of determining the aggregation level The blind detection success rate of signaling further reduces the number of blind detections of the terminal and reduces the complexity of the terminal side.

In the second embodiment, the candidate resource location of the auxiliary indication signaling is the auxiliary search space after removing the scheduling information sending time of the eMBB application data channel M ms or after M OFDM symbols, see FIG. 3.

Assume that two terminals UE1 and UE2 are scheduled on the network side, where UE1 transmits the eMBB application and UE2 transmits the URLLC application. The network side sends a UL grant in slot n to schedule UE1 to transmit eMBB PUSCH on slot n+2.

The network side enables the auxiliary indication signaling function for UE1 through RRC signaling, and the auxiliary indication signaling is sent through the downlink control channel. In this embodiment, the listening period of the auxiliary search space is 2-OS.

When the base station configures the candidate resource location of the auxiliary indication signaling, the base station only determines the starting point of the candidate resource location when it counts M ms or M OFDM symbols after sending the scheduling information of the eMBB application data channel; in the candidate resource location The auxiliary indication signaling is sent and received in the auxiliary search space after the starting point.

The above M is implicitly determined by the terminal capability, or pre-defined by the protocol, Or it can be configured through explicit signaling on the network side, such as RRC signaling.

Embodiment 3. The candidate resource location of the auxiliary indication signaling is the auxiliary search space between the time when the eMBB application data channel scheduling information is sent and the termination point of the candidate resource location, see FIG. 4.

Assume that two terminals UE1 and UE2 are scheduled on the network side, where UE1 transmits the eMBB application and UE2 transmits the URLLC application. The network side sends a UL grant in slot n to schedule UE1 to transmit eMBB PUSCH on slot n+2.

The network side enables the auxiliary indication signaling function for UE1 through RRC signaling, and the auxiliary indication signaling is sent through the downlink control channel. In this embodiment, the listening period of the auxiliary search space is 2-OS.

When the base station configures the position of candidate resources for auxiliary indication signaling, the base station counts forward to N OFDM symbols or N ms from the start position of the scheduled eMBB application data channel transmission time domain, and determines the end point of the candidate resource position ; In the auxiliary search space between the time when the eMBB application data channel scheduling information is sent and the termination point of the candidate resource location, the auxiliary indication signaling is sent and received.

The above-mentioned N is implicitly determined by terminal capabilities, or pre-defined by a protocol, or configured by explicit signaling on the network side, such as RRC signaling.

Embodiment 4: The candidate resource position of the auxiliary indication signaling is the auxiliary search space between the determined starting point of the candidate resource position and the determined ending point of the candidate resource position, see FIG. 5.

Assume that two terminals UE1 and UE2 are scheduled on the network side, where UE1 transmits the eMBB application and UE2 transmits the URLLC application. The network side sends a UL grant in slot n to schedule UE1 to transmit the eMBB application data PUSCH on slot n+2.

The network side enables the auxiliary indication signaling function for UE1 through RRC signaling, and the auxiliary indication signaling is sent through the downlink control channel. In this embodiment, the listening period of the auxiliary search space is 2-OS.

When the base station configures the candidate resource location of the auxiliary indication signaling, the base station determines the starting point of the candidate resource location when it counts M ms or M OFDM symbols after sending the scheduling information of the eMBB application data channel; and at the scheduled time When the start position of the eMBB application data transmission channel is counted forward to N OFDM symbols or N ms, the candidate resource position end point is determined; in the auxiliary search space between the candidate resource position start point and the candidate resource position end point Send and receive auxiliary indication signaling.

The foregoing M or N is implicitly determined by the terminal capability, or pre-defined by a protocol, or configured by explicit signaling on the network side, such as RRC signaling.

In addition, the first embodiment can also be combined with the second embodiment, the third embodiment, and the fourth embodiment respectively, so as to better reduce the loss of system resources on the respective basis.

In addition, the process of determining the position of the candidate resource when the reference signal bears the auxiliary indication signaling is the same as when the downlink control channel bears the auxiliary indication signaling, so it is not repeated here.
