Description

Information transmission method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a terminal device, and a network device.

Background

In a New Radio (NR) system of the fifth generation Mobile Communication (5G), services with different priorities are supported, such as enhanced Mobile Broadband (eMBB) service, Ultra Reliable and Ultra Low Latency Communication (URLLC) service, and mass Machine Type Communication (mtc) service. Service flows with extremely high time delay and high reliability requirements are scattered and happened irregularly, so that the multiplexing transmission of the service on the same resource can be supported, and the resource utilization rate can be greatly improved. However, multiplexed transmission may result in data transmission of one terminal colliding with data transmission of another terminal having a different traffic priority on the same resource.

Therefore, for uplink transmission, a low-priority service needs to stop transmission on a resource occupied by a high-priority service to avoid interference to the high-priority service, and at this time, a mechanism is needed to notify a terminal having the low-priority service to stop transmission on the corresponding resource. For downlink transmission, the information of the low-priority service is covered by the information of the high-priority service, and at this time, a mechanism is also needed to notify the terminal with the low-priority service whether the corresponding resource is interrupted or not, so as to avoid that the terminal with the low-priority service receives the information of other services as self information, which causes receiving errors and error propagation of subsequent retransmission and combination.

To address the above problem, an interrupt (interrupt) indication is introduced to implement the mechanism notification. But there is currently no provision for how to interrupt the transmission of the indication.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly and completely understood, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

The following describes background art for embodiments of the present invention.

In the 5G NR system, services with different priorities are supported, such as eMBB service and URLLC service, and further, mtc service may be supported. Service flows with extremely high time delay and high reliability requirements are scattered and happened irregularly, so that the multiplexing transmission of the service on the same resource can be supported, and the resource utilization rate can be greatly improved. However, multiplexed transmission may result in data transmissions of one terminal device colliding with data transmissions of another terminal device having a different traffic priority on the same resource.

For downlink transmission, since the network side device, for example, the base station, transmits, the base station may directly transmit the data of the high priority service over the data of the low priority service, but if the terminal device receiving the low priority service does not know such processing, the terminal device receives the data of other terminal devices as its own data, so that the detection performance is reduced, and the data of other terminal devices is retransmitted and combined as its own data when retransmission occurs, thereby causing error propagation. In order to solve the problem, an Interruption (Interruption) indication may be introduced, which is also called a preemption (preemption) indication for downlink transmission, and informs a terminal device having a low-priority service whether resources interrupted by other terminal devices exist in downlink data transmission resources of the terminal device and a position of the interrupted resources, so that the terminal device can correctly process received downlink data.

For uplink transmission, different terminal devices transmit data, and if two terminal devices transmit respective data on the same resource, mutual interference may occur. In order to avoid mutual interference, when there is a high-priority service to be transmitted on a certain resource, if transmission of other low-priority services has been scheduled on the resource, a mechanism is needed to notify the terminal device having the low-priority service to stop transmitting on the overlapped resource, i.e. to interrupt the indication, so as to ensure normal transmission of the high-priority service. To address the above problem, an interrupt (interrupt) indication is introduced to implement the mechanism notification. But there is currently no provision for how to interrupt the transmission of the indication.

In view of this, an embodiment of the present invention provides an information transmission method for providing a transmission mode of an interruption indication, and in the embodiment of the present invention, a first terminal device may monitor a first-type DCI, so as to determine resource allocation information of scheduling information of a second terminal in the first-type DCI, so as to determine whether there is an interruption of data transmission of the first terminal device by data transmission of the second terminal device according to a resource allocated to the second terminal device, that is, perform data transmission according to a priority of a service from the second terminal device being higher than a priority of a service of the first terminal device. The scheduling information in the first type of DCI may explicitly transmit the scheduling information of the second terminal device, and the resource allocation information may play an implicit indication of whether the first terminal has interruption, so that the interruption indication and the transmission of the scheduling information are implemented through the first type of DCI, and when the high reliability of the interruption indication is ensured, it is avoided that two independent DCIs with high reliability are transmitted respectively to reduce the transmission efficiency of the DCI.

The technical scheme provided by the embodiment of the invention is described in the following with the accompanying drawings of the specification.

Referring to fig. 1, an embodiment of the invention provides an information transmission method, and a flow of the method is described as follows. Since the information transmission method involves an interactive process between the terminal device and the network device, in the following description of the flow, the processes executed by the terminal device and the network device will be described together.

S101, the network equipment sends first-class downlink control information DCI to the first terminal equipment.

In this embodiment of the present invention, the first type of Downlink Control Information (DCI) may include at least one scheduling Information indication field, where each scheduling Information indication field is used to carry scheduling Information of the second terminal device.

The first terminal device may be a terminal device configured or supporting at least a first service type, that is, a terminal device configured or supporting a service with a priority lower than or equal to that of the first type. Alternatively, the first terminal device may be a terminal device that does not support the second service type, that is, a terminal that does not support the second service type or higher priority. Correspondingly, the second terminal device is a terminal device configured or supporting at least the second service type, that is, a terminal device configured or supporting a service with a priority higher than or equal to the second type.

The first service type is a low-priority service type, the second service type is a high-priority service type, for example, the first service type is an eMBB service, the second service type is a URLLC service, and then the first terminal device supports an eMBB service and the second terminal device supports a URLLC service. Or the first type of service and the second type of service are the same service type corresponding to different priorities, for example, the first type of service supports a URLLC service with a low priority, and the second type of service supports a URLLC service with a high priority, so that the first terminal device supports a URLLC service with a lower priority, and the second terminal device supports a URLLC service with a higher priority.

It should be noted that the first type of service and the second type of service may also be embodied by using a specific DCI format, a specific control-resource set (CORESET), a specific search space, a specific Radio Network Temporary Identifier (RNTI), a specific target Block Error Rate (BLER), a specific Channel Quality Indication (CQI)/Modulation and Coding scheme Multiple Code Word (MCS), and the like. A terminal device configured or supporting a certain service type may be embodied by using the above forms of specific DCI format, specific CORESET, specific search space, specific RNTI, specific target BLER, specific CQI/MCS table, etc. For example, the first terminal device and the second terminal device may be embodied in several forms:

in a first form: for example, the first type of traffic type may be equivalent to using the first type of DCI format to transmit the scheduling signaling, and the first terminal device may be a terminal device that uses the first type of DCI format to transmit the scheduling signaling. The second type of service may be equivalently that the scheduling signaling is transmitted using the second type of DCI format, and the second terminal device may be a terminal device that transmits the scheduling signaling using the second type of DCI format.

In a second form: for example, the first type of service may be equivalent to using the first CORESET or the first search space to transmit the scheduling signaling, and the first terminal device may be a terminal device that uses the first CORESET or the first search space to transmit the scheduling signaling. The second type of service may be equivalent to using the second CORESET or the second search space to transmit the scheduling signaling, and the second terminal device may be a terminal device that uses the second CORESET or the second search space to transmit the scheduling signaling.

In a third form: for example, the first type of traffic type may be equivalent to scrambling scheduling signaling using the first RNTI, and the first terminal device may be a terminal device which scrambles its scheduling signaling using the first RNTI. The second type of service may be equivalently that the scheduling signaling is scrambled by using the second RNTI, and the second terminal device may be a terminal device whose scheduling signaling is scrambled by using the second RNTI.

A fourth form: for example, the first type of traffic class may be equivalent to a target BLER lower than 10-5 or 10-6 (e.g., 10-2 or 10-1), and the first terminal device may be a terminal device with a target BLER lower than 10-5 or 10-6 (e.g., 10-2 or 10-1). The second type of traffic may be equivalent to a target BLER of 10-5 or 10-6, and the second terminal device may be a terminal device with a target BLER of 10-5 or 10-6.

The fifth form: for example, the first type of service type may be equivalently configured with a 64 Quadrature Amplitude Modulation (QAM)/256 QAM CQI table (corresponding to a 64QAM/256QAM MCS table), and the first terminal device is a terminal device configured with a 64QAM/256QAM CQI table. The second type of service type may be equivalent to a terminal device configured with a URLLC CQI table (MCS table corresponding to URLLC), and the second terminal device is equivalent to the terminal device configured with the URLLC CQI table.

In the embodiment of the present invention, no matter the first terminal device and the second terminal device adopt any one of the above five forms, the terminal and the network device can implicitly obtain the service types or the service priorities of the first terminal device and the second terminal device. The network device may generate scheduling information for each terminal device based on respective traffic to be performed by the plurality of second terminal devices, and the scheduling information is carried in the scheduling information indication domain of the first DCI, and time domain resources and/or frequency domain resources and other scheduling information are allocated to each second terminal device for each second terminal device to transmit services, the first terminal may obtain the position of the time domain resource and/or the frequency domain resource occupied by the second terminal device by reading the indication information (i.e. the first indication field) of the time domain resource and/or the frequency domain resource in the scheduling information of the first type of DCI carrying the scheduling information of the second terminal, so that the determination of whether there is an overlap with the position of the time domain resource and/or the frequency domain resource scheduled for data transmission itself can be made, thereby determining whether there is an interruption from the second terminal.

In a possible implementation, the first type of DCI may include a plurality of scheduling information indication fields, where each scheduling information indication field corresponds to a different second terminal device. Each scheduling information indication field may include a first indication field, and the network device may carry the time domain resources and/or the frequency domain resources allocated by each terminal device in the first indication field with the time domain resource indication information and/or the frequency domain resource indication information.

In possible embodiments, the first indication field may be embodied in the following forms:

the first method comprises the following steps: the first indication field may include only time domain resource indication information.

And the second method comprises the following steps: the first indication field may include only frequency domain resource indication information.

And the third is that: the first indication field may contain time domain resource indication information and frequency domain resource indication information.

In a possible embodiment, each scheduling information indication field is M bits, the first indication field may be N bits, and M, N are all positive integers. For example, the first indication field is located at a predetermined position in the scheduling information indication field, such as the first N bits, or the last N bits, etc. The first indication field may define a preset bit for indicating time domain resource indication information or frequency domain resource indication information. For example, a first preset bit in the first indication field is used for indicating the time domain resource indication information, and a second preset bit in the first indication field is used for indicating the frequency domain resource indication information.

In a possible embodiment, the first indication field and the M-N bits may be encoded independently, or the first indication field and the M-N bits may be encoded jointly. The first indication field is scrambled with the same or different RNTI as the M-N bits.

In a possible embodiment, M-N bits in each scheduling information indication field are used to indicate scheduling information of the corresponding second terminal device other than the information indicated by the first indication field.

For example, when a plurality of scheduling information indication fields are included in the first type of DCI, the functional division of the remaining bit information in each scheduling information indication field except the first indication field may be the same or different, and belongs to a terminal device specific to the corresponding terminal device, that is, determined according to the specific configuration or requirement of the terminal device corresponding to the scheduling information indication field. For example, X1 bits in the M-N bit information of a terminal device indicate Multiple Input Multiple Output (MIMO) configuration information. X2 bits among the M-N bit information of the other terminal device indicate MIMO configuration information and the like. There are X3 bit carrier indication information in the M-N bit information of one terminal device, X4 bit carrier indication information in the M-N bit information of another terminal device, and so on. Only by identifying the scheduling information indication domain belonging to a terminal, the terminal can determine the specific function division of the M-N bits in the scheduling information indication domain according to the configuration of the terminal.

In the embodiment of the present invention, when the first indication domain includes both the time domain resource indication information and the frequency domain resource indication information, the first indication domain is preset to include the time domain resource indication information with the fixed bit and the frequency domain resource indication information with the fixed bit, and the bit number and the dividing manner of the instant frequency domain resource indication are consistent for all terminal devices or the terminal devices monitoring the same first type of DCI, and are not related to the dedicated configuration of the terminal device, so that it can be ensured that the first terminal device determines whether the time frequency domain resource of the second terminal device conflicts with the self-scheduled time frequency domain resource by reading the time frequency domain resource indication information of the second terminal device.

The granularity or the candidate resource set of the time domain resources and/or the frequency domain resources indicated by the first indication field is consistent for all terminal devices or a group of terminal devices monitoring the same first type of DCI, that is, it is required to ensure that the number of bits of each first indication field is the same, and is not related to the exclusive configuration of the terminal device. Therefore, the first terminal device can be ensured to judge whether the transmission resource of the second terminal device conflicts with the self-scheduled transmission resource by reading the time domain resource indication information and/or the frequency domain resource indication information of the second terminal device. The number of bits is related to the size of the candidate set, and the first terminal device reads the indication field of the second terminal device, so that the first terminal device and the second terminal device need to have a consistent understanding of the result indicated by the indication field. For example, the first indication field only indicates time domain resources, and assuming that there are 2 bits indicating 4 preconfigured time domain positions, then all terminal devices transmitting in this first type of DCI have 2 bits in the first indication field in their scheduling information, and all select one from these 4 resources. Rather than say that one terminal device is 2 bits and the other terminal device is 3 bits; alternatively, both terminal devices are 2 bits, but the corresponding 4 candidate resources are different.

In the embodiment of the present invention, when the network device sends the first type of DCI to the first terminal device, the first type of DCI may be transmitted in a multicast transmission manner, and the multicast first type of DCI may be scrambled using a specific RNTI and transmitted in a specific search space. Specifically, when the network device transmits the first-type DCI to the first terminal device, the first-type DCI may be transmitted in each transmission opportunity of the first-type DCI. Alternatively, the network device may transmit the DCI of the first type in a transmission opportunity of the DCI of the first type after transmitting the scheduling signaling of the first terminal device. Or, the network device sends the first type of DCI in a transmission opportunity of the first type of DCI after sending the scheduling signaling of the first terminal device and before the scheduled uplink transmission ending position of the first terminal device.

Correspondingly, in S102, the first terminal device monitors DCI of the first type. In a possible embodiment, the first terminal device monitors the first type DCI at each transmission opportunity of the first type DCI. Or, the first terminal device monitors the first-class DCI in the transmission opportunity of the first-class DCI after receiving the self-scheduling signaling. Or the first terminal device monitors the first-class DCI in the transmission opportunity of the first-class DCI after receiving the self scheduling signaling and before the self scheduled uplink transmission ending position.

In a possible implementation, when the network device sends the first type of DCI to the first terminal device, the network device may instruct the first terminal device to only parse the first indication field in each scheduling information indication field in the first type of DCI. Alternatively, the network device may indicate that the first terminal device is capable of resolving the first indication field, and each scheduling information in the first type of DCI indicates information in the field other than the first indication field.

S103, the first terminal device transmits data according to the first indication domain in each scheduling information indication domain.

When the first type of DCI is received by the first terminal device, only the first indication field in each scheduling information indication field in the first type of DCI may be parsed to obtain the scheduling information of the time-frequency domain resources of the second terminal device, or the first indication field in each scheduling information indication field in the first type of DCI and information other than the first indication field are parsed to obtain complete scheduling information of the second terminal device, so as to perform data transmission according to the time-domain resource indication information and/or the frequency-domain resource indication information in the scheduling information.

Specifically, the first terminal device performs data transmission according to a first indication field in each scheduling information indication field, which may include the following cases:

in the first case: when the first terminal equipment carries out uplink transmission, the first terminal equipment determines that the transmission resource of the second terminal equipment is overlapped with the transmission resource of the first terminal equipment according to the first indication domain, and the first terminal equipment does not send information on the transmission resource determined according to the first indication domain; or the first terminal equipment stops the uplink transmission containing the transmission resource determined according to the first indication domain.

In the second case: when the first terminal equipment performs downlink transmission, the first terminal equipment determines that the transmission resource of the second terminal equipment is overlapped with the transmission resource of the first terminal equipment according to the first indication domain, and the first terminal equipment does not receive information on the transmission resource determined according to the first indication domain; or, the first terminal device sets the information received on the transmission resource determined according to the first indication field to 0; or the first terminal device determines that the information received on the transmission resource determined by the first indication domain does not participate in the subsequent retransmission combination.

In the third case: when the first terminal equipment carries out uplink transmission, the first terminal equipment determines that the transmission resource of the second terminal equipment is not overlapped with the transmission resource of the first terminal equipment according to the first indication domain, and then the uplink transmission is sent on the scheduled resource of the first terminal equipment.

In a fourth case: when the first terminal equipment performs downlink transmission, the first terminal equipment determines that the transmission resource of the second terminal equipment is not overlapped with the transmission resource of the first terminal equipment according to the first indication domain, and then receives downlink transmission on the scheduled resource of the first terminal equipment.

Correspondingly, S104, the network device performs data transmission with the first terminal device according to the first indication field in the at least one scheduling information indication field.

Specifically, the following conditions are included in the network device performing data transmission with the first terminal device according to the first indication domain in the at least one scheduling information indication domain:

in the first case: when the network device performs downlink transmission on the terminal device, the network device determines that the transmission resource of the second terminal device is overlapped with the transmission resource of the first terminal device according to the first indication domain, and the network device does not send downlink transmission aiming at the first terminal device on the transmission resource determined according to the first indication domain; or, the network device sets the information of the downlink transmission for the first terminal device on the transmission resource indicated by the first indication field to 0.

In the second case: when the terminal device performs uplink transmission on the network device, the network device determines that the transmission resource of the second terminal device is overlapped with the transmission resource of the first terminal device according to the first indication domain, and the network device does not receive the uplink transmission from the first terminal device on the transmission resource determined according to the first indication domain; or, the network device receives uplink transmission from the first terminal device corresponding to the transmission resource indicated by the first indication field.

In the third case: when the network device performs downlink transmission on the terminal device, the network device determines that the transmission resource of the second terminal device does not overlap with the transmission resource of the first terminal device according to the first indication domain, and then the network device sends the downlink transmission of the first terminal device on the scheduled resource of the first terminal device.

In a fourth case: when the terminal device performs uplink transmission on the network device, the network device determines that the transmission resource of the second terminal device does not overlap with the transmission resource of the first terminal device according to the first indication field, and then the network device receives the uplink transmission of the first terminal device on the scheduled resource of the first terminal device.

In order to facilitate understanding of the technical solutions provided by the embodiments of the present invention, the technical solutions provided by the embodiments of the present invention are described in detail with specific embodiments below.

In the embodiment of the present invention, an interruption indication of uplink transmission is taken as an example, it is assumed that a transmission opportunity of the first type DCI is shown in fig. 2, and a schematic structural diagram of a scheduling indication field in the first type DCI is shown in fig. 3. The URLLC terminal equipment of the scheduling information in the same first-class DCI is configured to receive the first-class DCI by using the same RNTI or receive a first indication domain in the first-class DCI. For example, the first RNTI is configured for reception of DCI of the first type, that is, DCI of the first type is scrambled using the first RNTI, or a first indication field in a scheduling information indication field for each URLLC terminal device in DCI of the first type is scrambled using the first RNTI. The following describes the information transmission flow of the network device and the terminal device, respectively, with respect to the above example.

In terms of the network device, it is assumed that the network device sends an Uplink (UL) grant in slot n-1 to schedule terminal device 1 to transmit a Physical Uplink Shared Channel (PUSCH) on the 4 th to 14 th symbols in slot n, and it is assumed that terminal device 1 (the first terminal device) does not support URLLC service, for example, it carries eMBB service, for example, terminal device 1 transmits its scheduling signaling using DCI-1 (DCI-1 is different from the first type DCI), or uses RNTI-1(RNTI-1 is different from the first RNTI), or uses CORESET-1 or SS-1 to transmit its scheduling signaling, or configures 64QAM/256QAM CQI table, or configures BLER to be 10-1 or 10-2, and so on. The network device may know that the terminal device 1 is the first terminal device (i.e., the terminal device supporting a service of a different type than the terminal device 2) in these ways.

Assuming that the network device subsequently determines that terminal device 2 (second terminal device) requests URLLC service transmission, the network device sends a first-type DCI in the transmission opportunity of the 1 st first-type DCI in slot n to schedule terminal device 2 to perform PUSCH transmission on the 5 th symbol in slot n; certainly, when the first-type DCI including the scheduling information of the terminal device 2 is sent, the first-type DCI may simultaneously include a plurality of such scheduling information indication fields, and each scheduling information indication field corresponds to a different URLLC terminal device, thereby implementing multicast of the scheduling information of the plurality of terminal devices, and reducing signaling overhead. For example, if there is a URLLC service in terminal device 3, for example, transmitted on the 7 th symbol in slot n, the network device may carry the scheduling information of terminal device 2 and terminal device 3 in the same first type of DCI for transmission, where terminal device 2 and terminal device 3 support the URLLC service, for example, transmit their scheduling signaling using the first type of DCI (certainly, it may also be configured to further transmit their scheduling signaling using DCI-2, that is, the scheduling signaling of terminal device 2 may be from the first type of DCI, or may also be from DCI-2), or use the first RNTI (of course, it may also be configured to further use RNTI-2), or send their scheduling signaling using CORESET or SS corresponding to the first type of DCI (of course, it may also be configured to further use CORESET or SS corresponding to DCI-2 to send their scheduling signaling), or configure to use URLLC CQI table, or configure BLER to be 10-5 or 10-6, and so on, the network device may know that terminal device 2 and terminal device 3 are the second terminal device (i.e., the terminal device supporting a different service type than terminal device 1) in these ways.

The first type of DCI carrying the scheduling information of the terminal device 2 and the terminal device 3 includes a plurality of scheduling information indication fields, each scheduling information indication field corresponds to one terminal device, and the corresponding relationship is determined in advance according to the configuration information or can be determined by the terminal device through detection (for example, detecting an RNTI scrambling sequence specific to the terminal, or detecting an indication field indicating an ID of the terminal device, etc. it is required to ensure that each scheduling information indication field includes a first indication field of a fixed bit for the non-URLLC terminal device to identify scheduling resources of the URLLC terminal device, for example, it is assumed that the terminal device 2 corresponds to the first scheduling information indication field in the first type of DCI, the terminal device 3 corresponds to the 2 nd scheduling information indication field in the first type of DCI, the scheduling information indication fields of the terminal device 2 and the terminal device 3 are both M bits, and both include N-bit first indication fields, the remaining M-N bits are indication information indicating other scheduling information, such as an indication field indicating a carrier number of cross-carrier scheduling (if cross-carrier scheduling is configured, the field exists, otherwise, the field does not exist), an indication field indicating a Part of a Bandwidth (BWP) number (several bits are determined according to the BWP number configured by the terminal device), an indication field indicating an MCS, a Redundancy Version (RV) of each codeword, a New Data Indicator (NDI) (related to the number of Transport Blocks (TBs) configured by the terminal device, one TB is one such indication field, and a plurality of TBs is a plurality of such indication fields), and the like, an indication field related to the terminal device configuration, the number of bits of which may be different between different terminals, depending on the specific configuration of the terminal device. Certainly, it may also be stipulated that all terminal devices performing scheduling signaling multicast in the same first-type DCI have the same indication domain division, that is, for a plurality of terminal devices performing multicast, the bit number of the first indication domain in the first-type DCI is fixed to N bits, and the total bit number of the scheduling information indication domain of each terminal device is also fixed, for example, to M bits, for one terminal device, if the bit number of the actually required time domain resource indication domain is less than N, it needs to be sent according to N bits, a zero padding mode may be adopted, if the bit number of the actually required time domain resource indication domain exceeds N, it needs to be sent according to N bits, a mode of removing some time domain candidate resources that cannot be indicated for use may be adopted, and similarly, the remaining M-N bit numbers may be the same for the specific indication domains of different terminal devices, it may also be different, if different, meaning that the other terminal device cannot read the remaining scheduling information that is not itself. When the network device sends the N bits and the M-N bits, a joint coding or independent coding mode can be adopted, the advance is defined, and the consistency with the terminal device detection mode is kept. When independent coding is adopted, N bits and M-N bits can be scrambled by using the first RNTI, and on the basis, the M-N bits can be further scrambled by using the special RNTI of the corresponding terminal equipment so as to distinguish different terminal equipment. Or, the terminal equipment exclusive RNTI is taken as an identifier and carried in the M-N bit indication domain as a terminal equipment ID indication domain, and each URLLC terminal equipment identifies whether the scheduling information indication domain is self-owned by reading the terminal equipment ID indication domain in the M-N bit. Of course, if the terminal devices included in one first-type DCI have been defined in advance, the corresponding relationship between the terminal devices and the scheduling information indication field in the first-type DCI may also be directly pre-configured, for example, the terminal device 2 is pre-configured to correspond to the first scheduling information indication field, and the terminal device 3 is configured to correspond to the second scheduling information indication field.

The setting of the N-bit first indication field in the first type DCI may be as follows:

mode 1: the first indication field may indicate only the time domain resource allocation, and the indication field of the frequency domain resource allocation is included in the N-M bits. At this time, it needs to be assumed that the candidate resource sets of the time domain resource allocations corresponding to the multiple URLLC terminal devices transmitting the scheduling information in the first type of DCI are the same, for example, the multiple URLLC terminal devices are all configured with the same 16 candidate resources in advance (each candidate resource at least includes information such as a start symbol position and a transmission length), and then the M-bit scheduling information of each second terminal device includes the N-4-bit first indication field, which may indicate one of the 16 candidate time domain resources.

Mode 2: the first indication field may also indicate both time and frequency domain resource allocations. At this time, it needs to be assumed that the candidate resource sets of the time domain resource allocation corresponding to the multiple URLLC terminal devices transmitting the scheduling information in the first type DCI are the same. For example, multiple URLLC terminal devices are all configured with the same 16 candidate resources in advance (each candidate resource includes at least one start symbol position, transmission length, and other information), then the M-bit scheduling information of each second terminal device includes 4-bit time domain resource indication information, which may indicate one of the 16 candidate time domain resources, and it needs to be assumed that the number of bits allocated to the frequency domain resources and the frequency domain resource dividing manner corresponding to the multiple URLLC terminal devices transmitting the scheduling information in the first type of DCI are the same. For example, frequency domain resource indication is performed according to the same BWP bandwidth and resource indication scheme (one of resource allocation schemes 0 or 1), and for example, assuming that 10-bit frequency domain indication fields are included, the bit number N of the first indication field is 14 bits.

In order to avoid the interference of the PUSCH of the terminal device 1 on the PUSCH of the terminal device 2, the network device assumes that the terminal device 1 may determine whether there is an interruption according to the first indication field when detecting the DCI of the first type, so as to determine whether to stop data transmission on the overlapping resources. The network device directly receives the PUSCH of the terminal device 2 on the overlapping resource without receiving the PUSCH of the terminal device 1, and of course, the network device may continue to receive the PUSCH of the terminal device 1 on the resource of the terminal device 1 without interruption, or may not receive the PUSCH of the terminal device 1 from the start position of the PUSCH of the terminal device 1 or from the start position of the PUSCH of the terminal device 1 with interruption. Similarly, for terminal device 3, since there is no overlap with the frequency domain resource of terminal device 1, the network device may receive the PUSCH of terminal device 1 and terminal device 2 simultaneously on the 7 th symbol in slot n.

For the terminal device: the terminal equipment monitors the first type DCI, the terminal equipment 1 monitors DCI-1 for scheduling PUSCH in the DCI transmission opportunity of the eMBB terminal equipment 1 in each time slot, and receives scheduling signaling for scheduling PUSCH transmission in the 4 th to 14 th symbols in the time slot n in the transmission opportunity of the time slot n-1. Or, the terminal device 1 monitors the first-type DCI in the first-type DCI transmission opportunity in each slot, or the terminal device 1 monitors the first-type DCI in the first-type DCI transmission opportunity only after receiving the DCI-1 for scheduling the terminal device 1 to perform PUSCH transmission and before the PUSCH end position of the terminal device 1. Then, the terminal device 1 monitors a first type DCI in a first type DCI transmission opportunity in the time slot n, and the terminal device 1 parses the first indication field in each scheduling information indication field in the first type DCI, determines whether there is an interruption, and further determines how to perform data transmission.

When monitoring the first-class DCI, the terminal device 1 monitors according to the fixed DCI size, where the DCI size is related to the number of scheduling information indication fields supported in the first-class DCI and the total bit number of each scheduling information indication field.

In a possible implementation manner, the terminal device 1 only analyzes the first indication field in each monitored scheduling information indication field in the first type of DCI, and analyzes the first indication field according to the bit number and the bit position of the first indication field. Alternatively, the terminal device 1 may not parse the indication information other than the first indication field in each scheduling information indication field. In the parsing process, the terminal device 1 is opposite to the network device side, and may assume that the first indication field and the remaining bits are jointly coded or independently coded, and may descramble the first indication field and the remaining bits using a corresponding RNTI.

Corresponding to the method 1: terminal device 1 assumes that each scheduling information indication field in the first type DCI includes a 4-bit first indication field and only indicates time domain resource allocation, reads the 4-bit information, and obtains the time domain resource allocation condition of each URLLC terminal device according to the 4-bit time domain resource indication information, and may determine whether there is an overlap with a transmission symbol of PUSCH scheduled by itself, and if there is an overlap with a time domain symbol, the first terminal device determines that there is an interruption on the symbol (i.e., whether there is an overlap with a frequency domain resource, it is considered that there is an interruption because the first terminal device cannot know the frequency domain resource allocation information of the second terminal device). For example, at this time, terminal device 1 determines that terminal device 2 is scheduled to transmit the 5 th symbol in slot n according to the 4-bit first indication field in the scheduling information indication field corresponding to terminal device 2 in the first type of DCI, so as to determine that there is an overlap with the PUSCH of itself. Similarly, the terminal device 1 may determine that there is a time domain symbol overlap between the terminal device 3 and the terminal device 1 by reading the first indication field in the scheduling information indication field of the corresponding terminal device 3 in the first DCI. Terminal apparatus 1 may directly stop PUSCH transmission (i.e. no transmission of the entire PUSCH) if it can resolve the first indication field before its PUSCH transmission. If the terminal apparatus 1 does not parse the first indication field before its PUSCH transmission, the PUSCH transmission may be stopped immediately after parsing the first indication field and making an interruption determination. Of course, the terminal device 1 may stop PUSCH transmission only on the 5 th and 7 th overlapping symbols and continue PUSCH transmission on other symbols, and it is specifically predefined which manner is adopted as long as it is consistent with the understanding of the network device.

The corresponding mode 2: terminal device 1 assumes that each scheduling information indication field in the first DCI includes a 14-bit first indication field with N being 4+10, and 4 bits indicate a time domain, and 10 bits indicate frequency domain resource allocation, and then reads the 14-bit information, and may obtain the time domain and frequency domain resource allocation condition of each URLLC terminal device according to the 4-bit time domain and 10-bit frequency domain resource allocation indication field in the scheduling information indication field of each terminal device in the first DCI. If the time domain symbols are overlapped, the terminal device 1 further determines whether the frequency domain resources are overlapped on the overlapped symbols, and there is an interruption on the resources where both the time domain and the frequency domain are overlapped, and of course, it may also first determine whether the frequency domains are overlapped, and determine whether the time domain symbols are overlapped on the overlapped portion of the frequency domains. For example, at this time, terminal device 1 determines, according to the 4-bit time domain indication field in the scheduling information indication field corresponding to terminal device 2 in the first type of DCI, that terminal device 2 is scheduled to transmit the 5 th symbol in time slot n, and overlaps with its own symbol, and determines, according to the 10-bit frequency domain indication field, that the frequency domain resource of terminal device 2 overlaps with its own frequency domain resource on symbol 5, then it is determined that terminal device 2 has an interruption to its transmission. Similarly, the terminal device 1 determines, according to the 4-bit time domain indication domain in the scheduling information indication domain corresponding to the terminal device 3 in the first type of DCI, that the terminal device 3 is scheduled to transmit the 7 th symbol in the time slot n, and determines, according to the 10-bit frequency domain indication domain, that the frequency domain resource of the terminal device 3 is not overlapped with the frequency domain resource of the terminal device 3 on the symbol 7, that there is no interruption to the transmission by the terminal device 3. Terminal apparatus 1 may directly stop PUSCH transmission (i.e. no transmission of the entire PUSCH) if it can resolve the first indication field before its PUSCH transmission. If the terminal apparatus 1 does not parse the first indication field before its PUSCH transmission, the PUSCH transmission may be stopped immediately after parsing the first indication field and making an interruption determination. Of course, the terminal device 1 may stop PUSCH transmission only on the 5 th symbol that overlaps, and continue PUSCH transmission on other symbols, which manner is specifically defined in advance may be adopted as long as it is consistent with the understanding of the network device.

In the embodiment of the present invention, terminal devices 2 and other terminal devices supporting the URLLC service monitor the first type DCI in the transmission opportunity of the first type DCI, and when the first type DCI is monitored, analyze the scheduling information indication field corresponding to the terminal device, and perform corresponding PUSCH transmission according to the scheduling information. The execution process of the terminal device 3 is similar to that of the terminal device 2, and is not described in detail here.

It should be noted that, in the above embodiments, the transmission opportunity of the first type DCI may also be 2 symbol intervals or 7 symbol intervals or longer, as shown in fig. 4 and fig. 5.

In summary, in the embodiment of the present invention, the first terminal device may monitor the first type DCI, so as to determine the resource allocation information of the scheduling information of the second terminal in the first type DCI, and determine whether there is an interruption of data transmission of the second terminal device to the data transmission of the first terminal device according to the resource allocated to the second terminal device, that is, perform data transmission according to a priority of a service from the second terminal device being higher than a priority of a service of the first terminal device. The scheduling information in the first type of DCI may explicitly transmit the scheduling information of the second terminal device, and the resource allocation information may play an implicit indication of whether the first terminal has interruption, so that the interruption indication and the transmission of the scheduling information are implemented through the first type of DCI, and when the high reliability of the interruption indication is ensured, it is avoided that two independent DCIs with high reliability are transmitted respectively to reduce the transmission efficiency of the DCI.
