Description

Method and equipment for sending and receiving auxiliary indication signaling

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for sending and receiving an auxiliary indication signaling.

Background

eMBB (enhanced Mobile Broadband) in 5G (fifth generation Mobile communication system), which has high tolerance for time delay and low reliability requirement, URLLC (Ultra-Reliable and Low latency communication, low time delay and high reliability communication), requires extremely low time delay and high reliability, and has the characteristic of burstiness, so that the priority of the URLLC service can be set to be higher than that of the eMBB service; after the network side schedules the eMMC service, if a service scheduling request of a URLLC from a terminal is received or the URLLC service sends data at a configured resource position which is overlapped with the eMMC service, in order to reduce the interference of the eMMC service channel on the URLLC service channel and avoid the reduction of the URLLC performance, the possible solution proposed at the present stage comprises the steps of canceling the sending of the eMMC data through information only carried by a downlink control channel, dynamically adjusting the transmitting power of the URLLC service channel, switching the resource position (Grant-free) of the URLLC service and the like.

Furthermore, there are many services with different priorities in the current communication system, and when the network side schedules a low-priority service and needs to schedule a higher-priority service on a resource already occupied by the low priority, a certain measure needs to be taken to reduce interference caused by the low-priority service to the high-priority service, for example, the terminal is notified to cancel the low-priority service, or suspend the transmission of the low-priority service, or increase the transmission power of the high-priority service.

In specific implementation, when an instruction is sent to notify the terminal to cancel the low-priority service, or the low-priority service is suspended from being sent, the method of canceling the low-priority service channel transmission by displaying an indication signaling indication brings extra resource overhead and improvement of terminal complexity. For example, the terminal needs to monitor more PDCCH (physical downlink control channel), which results in more blind detection and complexity of channel estimation. In addition, for the sequence-based scheme, since the reference signal needs to occupy periodic resources for transmission, these exclusive resources can severely consume the total number of available resources in the system, thereby reducing the system performance.

Therefore, in the prior art, when an instruction is sent to process a low-priority service partially overlapped with a high-priority service resource, the signaling overhead is large.

In specific implementation, the network side device determines the candidate resource position for sending the auxiliary indication signaling in an implicit mode, and does not need to additionally add a detection position for displaying the auxiliary indication signaling indicated by the indication signaling, so that the investment of the signaling is reduced, and further, the occupied system resources are reduced.

Therefore, the physical downlink control channel in the time domain resource is not monitored in the first time interval after the scheduling information of the low-priority service data channel is sent, the number of the physical downlink control channels which need to be detected by the terminal is reduced, the complexity of blind detection and channel estimation is reduced, meanwhile, the position of a candidate resource for sending the auxiliary indication signaling is determined in an implicit mode, signaling expenditure is reduced, and system performance is saved.

In this way, the terminal starts to detect the auxiliary indication signaling after receiving the scheduling information of the low-priority service data channel, and stops detecting the auxiliary indication signaling when the termination position point arrives. Therefore, the number of the physical downlink control channels monitored by the terminal is reduced, thereby reducing the complexity of blind detection and channel estimation, and meanwhile, the position of the candidate resource for sending the auxiliary indication signaling is determined in an implicit mode, thereby reducing signaling expenditure and saving system performance.

The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

In the embodiment of the invention, the terminal is a device with a wireless communication function, can be deployed on land and comprises an indoor or outdoor, handheld or vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiving function, a VR (virtual reality) terminal, an AR (augmented reality) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc.; but also UEs in various forms, Mobile Stations (MSs), terminal equipment (terminal devices).

The network side device is a device for providing a wireless communication function for a terminal, and includes but is not limited to: a gbb, an RNC (radio network controller), an NB (node B), a BSC (base station controller), a BTS (base transceiver station), an HNB (e.g., home evolved node B or home node B), a BBU (base band Unit), a TRP (transmission and reception point), a TP (transmission point), a mobile switching center, and the like in 5G. The base station in the embodiment of the present invention may also be a device that provides a wireless communication function for the terminal in other communication systems that may appear in the future.

The eMB service in the 5G system has high delay tolerance and lower reliability requirement; the URLLC service requires extremely low delay and high reliability, and has the characteristic of burstiness. In order to ensure that URLLC service data can be transmitted quickly and accurately, after network side equipment schedules an eMBB service, if a service scheduling request from a terminal URLLC is received or the URLLC service transmits data on a configured candidate resource position overlapping with the eMBB service, implementation of the URLLC service is preferentially ensured.

Thus, certain measures need to be taken to delay the eMBB service, or to reallocate resources for the URLLC service, for example, to cancel the transmission of eMBB data through the indication information carried by the downlink control channel, dynamically adjust the transmission power of the URLLC service channel, switch the candidate resource position (Grant-free) of the URLLC service, and the like. However, in any case, the extra signaling will bring overhead on resources or require higher terminal capability, thereby reducing system performance or increasing terminal processing complexity.

When the sending instruction informs the terminal to cancel the low-priority service or suspend sending the low-priority service, if the method of canceling the low-priority service channel transmission is indicated by the display indication signaling, additional resource overhead and improvement of the terminal complexity are brought. For example, the terminal needs to monitor more PDCCHs, resulting in more blind detection and complexity of channel estimation.

For the sequence-based scheme, since the reference signal needs to occupy periodic resources for transmission, the total number of available resources in the system is severely consumed by the exclusive resources, thereby reducing the system performance.

In the implementation, the network side device and the terminal determine the candidate resource position for sending and detecting the auxiliary indication signaling in an implicit mode, and do not need to additionally display the detection position of the auxiliary indication signaling indicated by the indication signaling, so that the signaling overhead is reduced, and the occupied system resources are reduced.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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.

In view of the above scenario, a schematic structural diagram of a system for sending and receiving an auxiliary indication signaling provided in an embodiment of the present invention is specifically shown in fig. 1, where the system includes:

the network side device 100, after sending the scheduling information of the low priority service data channel to the terminal, determines the candidate resource position for sending the auxiliary indication signaling in an implicit mode; sending the auxiliary indication signaling to the terminal on the candidate resource location; the auxiliary indication signaling is used for indicating a terminal to process a low-priority service data channel so as to reduce signal interference caused by transmission of the low-priority service data channel on a high-priority service data channel overlapped with resources of the low-priority service data channel.

The terminal 101 detects an auxiliary indication signaling on a candidate resource position determined in an implicit mode after receiving scheduling information of a low-priority service data channel; and after receiving the auxiliary indication signaling on the candidate resource position, processing a low-priority service data channel according to the auxiliary indication signaling so as to reduce signal interference caused by transmission of the low-priority service data channel on a high-priority service data channel overlapped with the resource of the low-priority service data channel.

In the embodiment of the invention, after a network side sends scheduling information of a low-priority service data channel to a terminal, a candidate resource position for sending an auxiliary indication signaling is determined in an implicit mode; then sending the auxiliary indication signaling to the terminal on the candidate resource position; then, the terminal detects an auxiliary indication signaling on the candidate resource position determined in an implicit mode; and after receiving the auxiliary indication signaling on the candidate resource position, processing the low-priority service data channel according to the auxiliary indication signaling so as to reduce the signal interference caused by the transmission of the low-priority service data channel on the high-priority service data channel overlapped with the resource thereof. In the specific implementation, the network side device and the terminal determine the candidate resource position of the auxiliary indication signaling for sending and detecting in an implicit mode, and do not need to add an additional display indication signaling to indicate the auxiliary indication signaling detection position, so that the signaling overhead is reduced, and the occupied system resources are reduced.

The low-priority service and the high-priority service in the embodiment of the invention are relative, and when the requirement of a communication service on the system is higher, the priority of the communication service is higher.

Such as: the eMB service in the 5G system has high delay tolerance and lower reliability requirement; the URLLC service requires extremely low delay and high reliability, and has the characteristic of burstiness. In comparison, when the request of the URLLC service to the system is higher than that of the eMBB service to the system when the service transmission is processed, the URLLC service is processed with priority, and when the priority indicates the request of the service processing, the priority of the URLLC service is considered to be higher than that of the eMBB service.

The terminal processes the low-priority service data channel according to the auxiliary indication signaling, generally cancels the transmission of the low-priority service data channel, suspends the transmission of the low-priority service data channel or reschedules the transmission of the low-priority service data channel, and reduces the transmitting power of the low-priority service data channel.

It should be noted that, for communication services that can be prioritized, the method in the embodiment of the present invention may be used to schedule and transmit communication services with different system requirements, and the 5G system is only one application scenario of the embodiment of the present invention, and is not limited to the embodiment of the present invention.

The embodiments of the present invention will be described in detail with reference to the following examples.

In specific implementation, first, the network side device needs to determine whether to adopt the scheme in the embodiment of the present invention.

Generally, a network side device may instruct a terminal to enable a candidate Resource location of the auxiliary indication signaling through a Radio Resource Control (RRC) signaling; or the terminal directly defaults to adopt the scheme of the embodiment of the invention to determine the candidate resource position of the auxiliary indication signaling.

On the basis, the terminal can detect the auxiliary indication signaling on the determined candidate resource position and process the low-priority service data according to the detected auxiliary indication signaling so as to reduce the signal interference caused by the transmission of the low-priority service data channel to the high-priority service data channel overlapped with the resource of the low-priority service data channel.

Further, after the scheme in the embodiment of the present invention is determined to be adopted, when it is necessary to schedule a higher priority service on the same resource after the low priority service data channel is scheduled, the network side device sends an auxiliary indication signaling to the terminal at the determined candidate resource position, and instructs the terminal to process the low priority service data channel on the same resource as the high priority service, so as to reduce signal interference caused by transmission of the low priority service data channel on the high priority service data channel overlapped with the resource of the low priority service data channel.

In a specific fact, the auxiliary indication signaling sent to the terminal by the network side device sends the auxiliary indication signaling to the terminal through a downlink control channel or a reference signal at the candidate resource position.

Which will be separately described below.

Firstly, auxiliary indication signaling is transmitted through a downlink control channel.

In the specific implementation process, after the network side device sends the scheduling information of the low-priority service data channel to the terminal, the candidate resource position for sending the auxiliary indication signaling is determined in an implicit mode.

In specific implementation, the network side device determines, in an implicit manner, a candidate resource location for sending the auxiliary indication signaling to be a downlink control channel resource in a time domain interval.

For the method of determining the candidate resource location of the auxiliary indication signaling by the network side device, three situations are determined for the candidate resource location for sending the auxiliary indication signaling.

In the first situation, the network side device determines the starting position point of the candidate resource position for sending the auxiliary indication signaling according to the time for sending the scheduling information of the low-priority service data channel and the preset first time interval.

Correspondingly, the terminal determines the initial position point of the candidate resource position for detecting the auxiliary indication signaling according to the time for receiving the scheduling information of the low-priority service data channel and the preset first time interval.

As shown in fig. 3, in this case, when the network side device processes the low-priority service data channel through the auxiliary indication signaling indication terminal, the network side device may start timing after sending the scheduling information of the low-priority service data channel to the terminal, and send the auxiliary indication signaling to the terminal until the preset first time interval is reached, and at the same time, after receiving the scheduling information of the low-priority service data channel, the terminal also starts timing, and until the preset first time interval is reached, the network side device starts detecting the auxiliary indication signaling at the candidate resource location. Therefore, the terminal does not need to monitor the physical downlink control channel in the time domain resource in the first time interval after the scheduling information of the low-priority service data channel is sent, so that the number of the physical downlink control channels which need to be detected by the terminal is reduced, the complexity of blind detection and channel estimation is reduced, meanwhile, the candidate resource position of the terminal detection auxiliary indication signaling is determined in an implicit mode, the signaling expenditure is reduced, and the system performance is saved.

The network side equipment determines an ending position point of a candidate resource position for sending an auxiliary indication signaling according to the initial time domain position of any priority service data channel and a preset second time interval;

correspondingly, the terminal determines the termination position point of the candidate resource position for detecting the auxiliary indication signaling according to the initial time domain position of any priority service data channel and the preset second time interval.

As shown in fig. 4, in this case, when the network side device processes the low priority service data channel through the auxiliary indication signaling indication terminal, it may select one priority service from all priority services, and determine, with the starting time domain position of the priority service data channel as a reference, an ending location point of a candidate resource location for sending the auxiliary indication signaling at a preset second time interval in a forward direction, and at the same time, the terminal determines, in the same manner, an ending location point of a candidate resource location for detecting the auxiliary indication signaling. In this way, the terminal starts to detect the auxiliary indication signaling after receiving the scheduling information of the low-priority service data channel, and stops detecting the auxiliary indication signaling when the termination position point arrives. Therefore, the number of the physical downlink control channels monitored by the terminal is reduced, thereby reducing the complexity of blind detection and channel estimation, and meanwhile, the candidate resource position of the auxiliary indication signaling detected by the terminal is determined in an implicit mode, thereby reducing signaling expenditure and saving system performance.

Determining, by the network side device, an initial position point of a candidate resource position for sending the auxiliary indication signaling according to a time for sending the scheduling information of the low-priority service data channel and a preset first time interval; and determining the termination position point of the candidate resource position for sending the auxiliary indication signaling according to the initial time domain position of any priority service data channel and a preset second time interval.

Correspondingly, the terminal determines an initial position point of a candidate resource position for detecting an auxiliary indication signaling according to the time for receiving the scheduling information of the low-priority service data channel and a preset first time interval; and determining the termination position point of the candidate resource position of the detection auxiliary indication signaling according to the initial time domain position of any priority service data channel and a preset second time interval.

As shown in fig. 5, in this case, when the network side device processes the low priority traffic data channel through the auxiliary indication signaling indication terminal, the network side device determines the starting location point for sending the auxiliary indication signaling and also determines the ending location point for sending the auxiliary indication signaling, and correspondingly, the network side device determines the starting location point for detecting the candidate location of the auxiliary indication signaling and also determines the ending location point for detecting the candidate location of the auxiliary indication signaling. Compared with the first case and the second case, in the third case, the candidate resource position of the terminal auxiliary indication signaling is further reduced, and the number of the physical downlink control channels monitored by the terminal is reduced, so that the complexity of blind detection and channel estimation is reduced, meanwhile, the candidate resource position of the terminal detection auxiliary indication signaling is determined in an implicit mode, the signaling expenditure is reduced, and the system performance is saved.

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

Then, after determining the candidate resource position for sending the auxiliary indication signaling, the network side equipment sends the auxiliary indication signaling for processing the low-priority service data channel by the indication terminal to the terminal;

correspondingly, the terminal detects and receives the auxiliary indication signaling on the candidate resource position of the corresponding auxiliary indication signaling.

Optionally, the network side device determines, according to the aggregation level used by the scheduling information of the low-priority traffic channel, an aggregation level used for sending an auxiliary indication signaling on the candidate resource location; sending the auxiliary indication signaling to the terminal at the position of the candidate resource according to the determined aggregation level;

correspondingly, the terminal determines the aggregation level used for receiving the auxiliary indication signaling on the candidate resource position according to the aggregation level used by the received scheduling information of the low-priority service data channel; and detecting an auxiliary indication signaling on the candidate resource location according to the determined aggregation level.

In the 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 low-priority service data channel, and complete the sending and receiving of the auxiliary indication signaling according to the determined aggregation level corresponding to the auxiliary indication signaling, and the aggregation level used by the auxiliary indication signaling is ensured to be greater than or equal to the aggregation level used by the scheduling information. Therefore, after the aggregation level used by the scheduling information of the low-priority service data channel is determined, the aggregation level corresponding to the auxiliary indication signaling is greater than or equal to the aggregation level used by the scheduling information, so that the blind detection success rate of the terminal for detecting the auxiliary indication signaling is improved, the blind detection times of the terminal are further reduced, and the complexity of the terminal side is reduced.

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

In a specific implementation, when the auxiliary indication signaling is carried on the downlink control channel, the auxiliary search space may configure multiple aggregation levels.

For example, the aggregation level {1, 2, 4, 8, 16}, the eMBB traffic is low priority traffic, and the base station and the terminal may refer to the corresponding PDCCH aggregation level used for scheduling the eMBB traffic to determine the aggregation level used for the assistance indication signaling transmitted in the assistance search space of the candidate resource location.

Assuming that the aggregation level AL is 2 when the base station schedules an eMBB PUSCH (Physical Uplink Shared Channel), when the auxiliary indication information is transmitted in the auxiliary search space of the candidate resource location, the aggregation level may be determined by using the following strategy:

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

The aggregation level used when the network side equipment sends the scheduling information of the eMB service data channel to the terminal is the aggregation level corresponding to the auxiliary indication signaling when the network side equipment sends the auxiliary indication signaling to the terminal.

2. Determining an aggregation level used by the auxiliary indication information according to a certain offset;

if offset is set to 1, the auxiliary indication information is used at the aggregation level AL_{Assistance of}＝AL_Scheduling+1 and the maximum usable polymerization grade AL ═ 16;

when the aggregation level used when the network side device sends the scheduling information of the eMBB service data channel to the terminal is 4, the aggregation level used when the network side device sends the auxiliary indication signaling is 8.

3. The corresponding relation between the aggregation grade used by the scheduling information of the low-priority service data channel and the aggregation grade used by the auxiliary indication signaling can be preset, and then the aggregation grade used by the auxiliary indication signaling is received and sent by the terminal and the network side equipment according to the aggregation grade used by the scheduling information of the low-priority service data channel.

For example: the following table is a corresponding relationship between the aggregation level used for setting the scheduling information of the low-priority service data channel and the aggregation level used for the auxiliary indication signaling:

when it is determined that the aggregation level used by the network side device to transmit the scheduling information of the eMBB service data channel is 4, as can be seen from the above table, the aggregation level used by the network side device to transmit the auxiliary indication signaling is 8, and the aggregation level used by the network side device and the terminal to determine to transmit and detect the auxiliary indication signaling is 8.

It should be noted that, in the specific implementation of the embodiment of the present invention, three schemes for determining candidate resource locations for sending and detecting the auxiliary indication signaling and determining the aggregation level corresponding to the auxiliary indication signaling may be respectively used in combination, so that the system resource loss may be better reduced on a corresponding basis.

Further, after detecting the auxiliary indication signaling at the determined candidate resource position of the auxiliary indication signaling, the terminal processes the low-priority service data channel according to the received auxiliary indication signaling, so as to reduce signal interference caused by transmission of the low-priority service data channel on the high-priority service data channel overlapped with the resource thereof.

Optionally, the auxiliary indication signaling includes one of the following functions:

indicating to reschedule the low-priority service data transmission;

indicating the cancellation of the low priority traffic data channel;

indicating a low priority traffic data channel suspension;

In specific implementation, the auxiliary indication information detected by the terminal carries one of the functions; when the auxiliary indication signaling comprises signaling for indicating the low-priority service data transmission to be rescheduled, and after the network side schedules the low-priority service, and needs to schedule a high-priority service data channel on the resource overlapped with the low-priority service data channel, the network side equipment sends the auxiliary indication signaling containing the function of indicating the low-priority service data transmission to the terminal, and indicates the terminal to reschedule the low-priority service data transmission and scheduling resource;

when the auxiliary indication signaling comprises a signaling for indicating the cancellation of the low-priority service data channel, and after the network side schedules the low-priority service, and needs to schedule the high-priority service data channel on the resource overlapped with the low-priority service data channel, the network side equipment sends the auxiliary indication signaling containing the function for indicating the cancellation of the low-priority service data channel to the terminal, and indicates the terminal to cancel the resource overlapped with the high-priority service data channel configured for the low-priority service data channel, namely indicates the terminal to release the resource occupied by the low-priority service data channel for the transmission of the high-priority service;

when the auxiliary indication signaling comprises signaling indicating the suspension of the low-priority service data channel, and after the network side schedules a low-priority service and needs to schedule a high-priority service data channel on a resource overlapped with the low-priority service data channel, the network side equipment sends the auxiliary indication signaling containing the suspension function of the low-priority service data channel to the terminal, indicates the terminal to suspend the transmission of the low-priority service data on a resource shared by the low-priority service data channel and the high-priority service data channel, and resumes the transmission of the low-priority service data after the transmission of the high-priority service data is preferentially completed;

when the auxiliary indication signaling comprises a signaling for indicating a low-priority service data channel to reduce the transmission power, and after the network side schedules a low-priority service, and needs to schedule a high-priority service data channel on a resource overlapped with the low-priority service data channel, the network side equipment sends the auxiliary indication signaling containing the function of indicating the suspension of the low-priority service data channel to the terminal, and indicates the terminal to reduce the transmission power of the low-priority service data channel during transmission of the low-priority service data channel on the resource shared by the low-priority service data channel and the high-priority service data channel, so as to reduce the interference of the transmission of the low-priority service data channel on the transmission of the high-priority service data channel.

And secondly, transmitting auxiliary indication signaling through a reference signal.

In specific implementation, the network side device determines, in an implicit manner, a candidate resource location for sending the auxiliary indication signaling to be a reference signal resource in a time domain.

The preset first time interval may be configured by the network side device, may also be implicitly determined according to the capability of the terminal, or may be predefined through a protocol.

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

In a specific implementation, after detecting the auxiliary indication signaling at the determined candidate resource position of the auxiliary indication signaling, the terminal processes the low-priority service data channel according to the received auxiliary indication signaling, so as to reduce signal interference caused by transmission of the low-priority service data channel on the high-priority service data channel overlapped with the resource of the low-priority service data channel.

indicating to reschedule the low-priority service data transmission;

indicating the cancellation of the low priority traffic data channel;

indicating a low priority traffic data channel suspension;

After the network side device and the terminal determine the time domain position of the reference signal which needs to send and monitor the bearing auxiliary indication signaling through the method, other channels or signal transmission can be scheduled on the resource reserved for the reference signal at the non-detection position, so that the resource utilization efficiency is improved.

In the following, a description will be given of an example in which, in a 5G system, after scheduling the eMBB service, it is necessary to schedule the URLLC service on the resource to which the eMBB service is scheduled.

In the first embodiment, the candidate resource locations for the auxiliary indication signaling are the entire auxiliary search space, as shown in fig. 2.

Assume that the network side schedules two terminals UE1 and UE2, where UE1 transmits eMBB traffic and UE2 transmits URLLC traffic. The network side sends a UL grant (uplink scheduling grant) at slot n to schedule UE1 to transmit an eMBB PUSCH at slot n +2 (slot n +2), where the aggregation level used by the scheduling information of the eMBB service of UE1 is 4.

The network side starts an auxiliary indication signaling function for the UE1 through RRC signaling, where the auxiliary indication signaling is sent through a downlink control channel, and a listening period of the auxiliary search space in this embodiment is 2-OS (2 ofdm (orthogonal frequency Division Multiplexing) symbols).

The base station can set all search spaces after transmitting eMBB service data channel scheduling information as candidate resource positions of the auxiliary indication signaling, and does not limit the candidate resource positions for receiving and transmitting the auxiliary indication signaling;

and when the auxiliary indication signaling is sent, setting the aggregation level used for sending the auxiliary indication signaling to be greater than or equal to the aggregation level used by the scheduling information of the eMBB service, for example, the aggregation level adopted by the auxiliary indication signaling is 8, so that the blind detection success rate of the terminal for detecting the auxiliary indication signaling can be improved according to a mode of determining the aggregation level, the blind detection times of the terminal are further reduced, and the complexity of the terminal side is reduced.

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

Assume that the network side schedules two terminals UE1 and UE2, where UE1 transmits eMBB traffic and UE2 transmits URLLC traffic. The network side sends a UL grant at slot n to schedule UE1 to transmit eMBB PUSCH at slot n + 2.

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

When the base station configures the candidate resource position of the auxiliary indication signaling, the base station determines the starting point of the candidate resource position only after the base station sends the scheduling information of the eMBB service data channel and counts M ms or M OFDM symbols;

and transmitting and receiving auxiliary indication signaling in an auxiliary search space after the starting point of the candidate resource position.

The M is determined implicitly by the terminal capability, or predefined by a protocol, or configured by explicit signaling on the network side, such as RRC signaling.

In the third embodiment, the candidate resource location of the auxiliary indication signaling is an auxiliary search space between the time when the eMBB service data channel scheduling information is sent and the termination point of the candidate resource location, see fig. 4.

When the base station configures the candidate resource position of the auxiliary indication signaling, the base station determines the candidate resource position termination point when the starting position point of the transmission time domain of the scheduled eMB service data channel counts forward to N OFDM symbols or N ms;

and transmitting and receiving auxiliary indication signaling in an auxiliary search space between the time of transmitting the eMBB service data channel scheduling information and the candidate resource position termination point.

The N is implicitly determined by the terminal capability, or predefined by a protocol, or configured by explicit signaling on the network side, such as RRC signaling.

In the fourth embodiment, the candidate resource location of the auxiliary indication signaling is an auxiliary search space between the determined starting point of the candidate resource location and the determined ending point of the candidate resource location, see fig. 5.

Assume that the network side schedules two terminals UE1 and UE2, where UE1 transmits eMBB traffic and UE2 transmits URLLC traffic. The network side sends UL grant at slot n to schedule UE1 to transmit eMBB service data PUSCH at slot n + 2.

When the base station configures the candidate resource position of the auxiliary indication signaling, the base station determines the starting point of the candidate resource position when counting to M ms or M OFDM symbols after sending the scheduling information of the eMBB service data channel;

when the starting position point of the scheduled eMB service data transmission channel counts forward to N OFDM symbols or N ms, determining a candidate resource position termination point;

and transmitting and receiving auxiliary indication signaling in an auxiliary search space between the starting point of the candidate resource position and the ending point of the candidate resource position.

The M or N is determined implicitly through the terminal capability, or predefined through a protocol, or configured through explicit signaling on the network side, such as RRC signaling.

In addition, the first embodiment may be respectively combined with the second embodiment, the third embodiment and the fourth embodiment, so that the system resource loss may be further reduced on the respective basis.

In addition, the procedure of the reference signal carrying auxiliary indication signaling when determining the candidate resource position is the same as that of the downlink control channel carrying auxiliary indication signaling, and therefore, the description is omitted.
