Description
Technical Field

Background
The fifth generation Mobile Communication system (5G) will support multiple service scenarios, such as enhanced Mobile Broadband (eMBB), ultra-Reliable Low latency Communication (URLLC), mass Machine Type Communication (mtc), etc.
The delay of URLLC service such as industrial automation, internet of vehicles, remote control, smart grid, virtual reality and the like has high requirements, and the end-to-end delay is less than 1ms even 0.5ms. In order to meet the delay requirement, especially reduce the uplink data transmission delay, one way is to configure predefined resources for the user terminal, and the user transmits the uplink data in a scheduling free (Grant free) manner, that is, the user directly transmits the uplink data on the predefined resources without the base station transmitting the uplink scheduling.
However, configuring too many predefined resources may result in a reduction in system efficiency. To improve system efficiency, the base station may transmit uplink traffic scheduled by the base station, such as eMBB traffic, on the scheduling-free resource. At this time, eMBB data transmitted by the base station scheduling method and URLLC data transmitted by the scheduling-free method may coexist on the scheduling-free resources, and further, interference of the eMBB user on the URLLC user on the scheduling-free resources may be caused. Considering that URLLC traffic is generally higher in priority and usually causes a significant accident when data loss occurs, it is desirable to reduce interference between users as much as possible while ensuring system efficiency. There is currently no effective solution to this problem.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail in the following with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
First embodiment
The present embodiment provides a data transmission method, please refer to fig. 1, the data transmission method includes:
s101, determining at least two service data to be transmitted, wherein the service data comprises service data of a first service type and/or service data of a second service type;
s102, transmitting the service data according to a preset rule; wherein, the preset rule comprises: the transmission modes of the same service data on different frequency domain resources are different, and/or the transmission modes of different service data are different.
Specifically, the preset rule includes at least one of the following rules:
the first transmission mode is different from the second transmission mode; the transmission mode on the resource for transmitting the first service type is a first transmission mode, and the transmission mode on the resource for transmitting the second service type is a second transmission mode;
the third transmission mode is different from the fourth transmission mode; the third transmission mode is a transmission mode transmitted on a third transmission resource, the third transmission resource is a resource which transmits the first service type and is overlapped with the second transmission resource, and the second transmission resource is a reserved scheduling-free resource configured in a transmission time unit; the fourth transmission mode is a transmission mode transmitted on a fourth transmission resource, and the fourth transmission resource is a non-overlapping resource between a resource for transmitting the first service type and the second transmission resource;
the second transmission mode is different from the third transmission mode;
the transmission modes of the transmission resources which are not overlapped in the time domain are different.
The types of the service data are divided into a first service type and a second service type in this embodiment, where the first service type and the second service type may be different service types or the same service type. Specifically, the first service type may be eMBB, the second service type may be URLLC, or both the first service type and the second service type may be eMBB or URLLC.
Referring to fig. 2, fig. 2 shows a schematic configuration of multiple types of transmission resources, where a first transmission resource represents a time-frequency resource in a transmission time unit, a second transmission resource represents a time-frequency resource in the transmission time unit, that is, a reserved scheduling-free resource configured in the first transmission resource, a third transmission resource refers to a resource that transmits a first traffic type and overlaps with the second transmission resource, and a third transmission resource represents a non-overlapping resource between the resource that transmits the first traffic type and the second transmission resource, that is, a resource that transmits the first traffic type, excluding the third transmission resource. In addition, a fifth transmission resource may be further included, where the fifth transmission resource is a resource that transmits the first traffic type and is not overlapped in a time domain with the second transmission resource, that is, a resource that does not collide in the time domain, and whether the resources are overlapped in the frequency domain is not limited.
In this embodiment, the transmission may include at least one of the following rules:
the first transmission mode is different from the second transmission mode; since the first transmission mode is a transmission mode on a resource for transmitting the first service type and the second transmission mode is a transmission mode on a resource for transmitting the second service type, the two transmission modes are different, that is, the transmission modes for respectively transmitting the first service type and the second service type are directly limited to be different. When the service data of the first service type is transmitted, the transmission resource for transmitting the first service type may be split, for example, the transmission resource may be split into a third transmission resource and a fourth transmission resource, and a fifth transmission resource may be optionally split into the fourth transmission resource. That is, the resource for transmitting the first service type may be divided into a plurality of resources, and the respective transmission modes of the plurality of resources may be different from each other, or still the same, and at least one of the plurality of resources is different from the transmission mode of the resource for transmitting the second service type.
The third transmission mode is different from the fourth transmission mode; the third transmission mode and the fourth transmission mode are different in that whether their corresponding transmission resources overlap with the second transmission resources, that is, the reserved scheduling-free resources; for the opposite end, the reserved scheduling-free resource is clear for the opposite end, that is, the second transmission resource is known by the opposite end, but the resource actually occupied by the transmission of the first service type is not implemented according to the reserved scheduling-free resource, so that whether the resource is overlapped with the reserved scheduling-free resource, that is, the respective transmission modes of the third transmission resource and the fourth transmission resource are distinguished to clear the difference between the two resources and avoid the occurrence of interference.
The transmission modes of the transmission resources which are not overlapped in the time domain are different. The non-overlapping of the time domains means that the two resources are not overlapped on the time domain, that is, the transmission resources are distinguished on the time axis, and if the time domains of the two resources are not overlapped, different transmission modes are adopted for transmission; and if the time domains of the two resources are overlapped, the same transmission mode can be adopted for transmission.
In some embodiments, the difference in transmission modes between the transmission resources whose time domains do not overlap may include:
the third transmission mode and the fifth transmission mode are different; the fifth transmission mode is a transmission mode on a fifth transmission resource, and the fifth transmission resource is a resource which transmits the non-time domain overlapping between the resource of the first service type and the second transmission resource.
In some embodiments, it may further be included that the priority of the second traffic type is greater than the priority of the first traffic type. Because the first service type is generally eMBB, the second service type is URLLC, and the priority requirement of the URLLC is higher, the priority of the second service type is higher because the first service type has a stricter requirement on time delay; of course, the first service type and the second service type may be eMBB or URLLC at the same time.
In some embodiments, the different transmission modes may include: the following configurations for each transmission mode: at least one of constellation Modulation, MCS (Modulation and Coding Scheme), power control, and code resources is different. The Code resource may include an Orthogonal Code OCC (Orthogonal Code).
In some embodiments, the constellation modulation difference may include:

The constellation modulation used for the service data of the second service type is defined as ≥>
Wherein m is a modulation order, and i is an ith constellation point index; the constellation modulation adopted by the service data of the first service type and the service data of the second service type during uplink transmission meets a first modulation relation, wherein the first modulation relation is as follows: for the same modulation order m, for the same constellation point index i, there are: u. of i ＝e i ·exp(jθ i ) Wherein i, θ is indexed for at least one constellation point i ≠0。
In some embodiments, the first modulation relationship is not satisfied for all modulation orders M, i.e., the modulation orders may be integers greater than or equal to N and less than or equal to M. Such as N =2,m =4 or 6.
In some embodiments, it may further include: the phase of the constellation modulation adopted by the service data of the first service type and the service data of the second service type in the downlink transmission process is the same; or the like, or, alternatively,
the constellation modulation adopted by the service data of the first service type and the service data of the second service type in the downlink transmission process meets a first modulation relation.
In some embodiments, it may further include: the first transmission method is the same as at least one of the third transmission method, the fourth transmission method and the fifth transmission method.
In some embodiments, it may further include: and when the third transmission mode is different from the fourth transmission mode, the redundancy version RV of the third transmission mode is different from that of the fourth transmission mode.
In some embodiments, it may further include: and when the third transmission mode is different from the fourth transmission mode, the third transmission mode and the fourth transmission mode adopt the same set of codes, the coded bits are divided into two parts, and the bits of the two parts are respectively mapped to the third transmission resource and the fourth transmission resource.
In some embodiments, it may further include: at least two of the sixth transmission mode, the third transmission mode and the fifth transmission mode are different; the sixth transmission mode is a mode of transmitting on a sixth transmission resource, and the sixth transmission resource is a resource that transmits the first traffic type and the second transmission resource, which are overlapped in time domain but not overlapped in frequency domain.
In some embodiments, it may further include: among the sixth transmission mode, the third transmission mode and the fifth transmission mode, at least two of them are different and include:
the redundancy versions RV of the sixth transmission scheme, the third transmission scheme, and the fifth transmission scheme are different for at least the two schemes.
In some embodiments, it may further include: among the sixth transmission mode, the third transmission mode and the fifth transmission mode, at least two of them are different and include:
and the sixth transmission mode, the third transmission mode and the fifth transmission mode adopt the same set of codes, the coded bits are divided into three parts, and the bits of the three parts are respectively mapped to the sixth transmission resource, the third transmission resource and the fifth transmission resource.

According to the data transmission method provided by the embodiment of the invention, the service data are transmitted differentially according to at least one of the type of the service data, the scheduling condition of the service data and the time domain overlapping condition of the service data, so that the interference in the service data transmission process is reduced in some implementation processes, and the transmission quality is improved.
Second embodiment
Different service types such as eMBB and URLLC can be supported in the 5G system, the eMBB is defined as a first service type, and the URLLC is defined as a second service type. A schematic diagram of various transmission resource configurations is given in fig. 2. Defining time frequency resources in a certain transmission time unit as first transmission resources. For uplink data transmission, to avoid scheduling delay, the base station may configure a part of the time-frequency resources as reserved scheduling-free resources, and define the reserved scheduling-free resources configured in the first transmission resources as second transmission resources.
The transmission resources of multiple types overlap each other in the figure. Wherein, part or all of the resources of the first service type are scheduled (or called as transmission) to belong to the second transmission resources, and the resources for scheduling the overlapping of the resources of the first service type and the second transmission resources are defined as the third transmission resources. Since the third transmission resource may collide with the resource for actually transmitting the second service type, different transmission modes need to be defined for the different transmission resource positions.
Optionally, a non-overlapping resource between the resource for transmitting the first service type and the second transmission resource is defined as a fourth transmission resource, and a non-time-domain overlapping resource between the resource for transmitting the first service type and the second transmission resource is defined as a fifth transmission resource. Since the fourth and fifth transmission resources are not likely to collide with the resource transmission for transmitting the second traffic type, the transmission mode can be more flexible.
Optionally, a corresponding transmission mode is defined for data transmission on different resources: the first transmission mode is as follows: a transmission mode on a resource transmitting the first service type; a second transmission mode: a transmission mode on a resource transmitting the second service type; a third transmission mode: transmitting the transmission mode of the user of the first service type on the third transmission resource; a fourth transmission mode: a transmission mode on a fourth transmission resource; a fifth transmission mode: a transmission mode on a fifth transmission resource.
Correspondingly, the relation among the transmission modes at least meets one of the following conditions:
the second transmission mode is different from the first transmission mode;
the second transmission mode is different from the third transmission mode;
the second transmission mode is different from the fourth transmission mode;
the second transmission mode is different from the fifth transmission mode; the third transmission method, the third transmission method and the fifth transmission method are all a subset of the first transmission method, and therefore the second transmission method is different from the first transmission methods, that is, different from the first transmission methods.
The third transmission mode is different from the fourth transmission mode.
The third transmission mode is different from the fifth transmission mode.
Optionally, the transmission modes are different, and the characteristics are that at least one of the following configurations is different: there are differences in constellation modulation, MCS, power control, OCC, etc.
Optionally, the first service type and the second service type may both be eMBB or URLLC, and the second service type has a higher priority than the first service type.
By the method of the embodiment, constellation modulation adopted by the eMBB UE and the URLLC UE on the overlapped resources has certain phase rotation, so that the interference between the eMBB UE and the URLLC UE can be reduced, the normal transmission of the URLLC service is ensured, and the higher eMBB service transmission efficiency is kept.
Third embodiment
The present embodiment relates to the relationship between modulation schemes of eMBB and URLLC UEs on overlapping resources.
Definition of constellation modulation that eMBB UE may employ is defined as
The constellation modulation employed by the URLLC UE is defined as ^ or ^>
Where m is a modulation order, the subscript i represents the ith constellation point, and i is a decimal number corresponding to a binary bit, for example, for QPSK (Quadrature Phase Shift keying) modulation, the constellation point index corresponding to bit "10" is i =2. Defining a first modulation relationship as: for the same modulation order m, index i, u for the same constellation point i ＝e i ·exp(jθ i ) Wherein for at least one index i, theta i ≠0。
Optionally, the constellation modulation adopted by the eMBB UE and the URLLC UE always has the first modulation relationship, and is independent of the used resource location. Or, the phases of the constellation modulations adopted by the eMBB UE and the URLLC UE in the downlink transmission are the same, and the constellation modulations adopted in the uplink always have the first modulation relationship.
Referring to fig. 3, fig. 3 shows a partial constellation modulation scheme adopted by different transmission schemes. The black constellation point gives a modulation mode used by the eMBB UE when the eMBB UE transmits on the third transmission resource by adopting the third transmission mode. In the example, the modulation scheme adopted by the third transmission scheme is a partial constellation modulation scheme (mainly including pi/2-BPSK, BPSK (Binary Phase Shift Keying) and QPSK) defined by an NR (New Radio, new air interface) protocol. In addition, a constellation modulation mode adopted by the URLLC UE on the resources for actually transmitting the service is provided. In the example, the modulation scheme used by the third transmission scheme is phase-rotated based on a partial constellation modulation scheme (mainly including pi/2-BPSK, QPSK) defined by the current NR protocol. Optionally, the eMBB UE and the URLLC UE use the same or different transmit powers.
Generally, when the eMBB UE transmits data at least on the third transmission resource by using the third transmission method, a certain relationship exists between the selectable constellation modulation and the constellation modulation selectable by the URLLC UE. Specifically, for example, when the URLLC UE employs QPSK modulation, the eMBB UE must employ a modulation scheme with a modulation order of 2 to 6 at least on the third transmission resource. Optionally, a constellation modulation order range adopted by the eMBB UE in the third transmission mode is at least but not limited to be determined by a constellation modulation order range adopted by the URLLC UE; or, the constellation modulation order range adopted by the URLLC UE is at least but not limited to the constellation modulation order range adopted by the third transmission mode of the eMBB UE.
As the modulation scheme is usually determined by MCS, optionally, the MCS range adopted by the third transmission scheme of the eMBB UE is at least but not limited to the MCS range adopted by the URLLC UE; alternatively, the MCS range employed by the URLLC UE is determined by at least, but not limited to, the MCS range employed by the eMBB UE third transmission scheme.
Since data of multiple URLLC UEs may be transmitted on the scheduling-free resource, different URLLC UEs may be configured with different constellations. Optionally, a corresponding relationship exists between a modulation scheme adopted by at least the third transmission scheme of the eMBB UE and a modulation scheme configured by the plurality of URLLC UEs. For example, the modulation scheme adopted by URLLC UE # i may limit the modulation scheme adopted by the eMBB UE to a set S _ i, and the modulation scheme available to the eMBB is the intersection of all S _ i, i =0, 1.
Fourth embodiment
The present embodiments relate to different transmission schemes employed by an eMBB UE on different resources.
For the eMBB UE, the same transmission method may be used for transmitting on all the scheduled transmission resources, that is, the first transmission method is used for transmitting, that is, the first transmission method is the same as the third transmission method, the fourth transmission method, and the fifth transmission method. I.e. the MCS, power, coding, etc. used on all transmission resources are the same. The method is beneficial to the rapid preparation of the UE end and the rapid decoding of the receiving end. Optionally, the first transmission mode is different from the second transmission mode.
Optionally, in order to reduce interference of the eMBB UE to the URLLC UE and improve the transmission efficiency of the eMBB UE, the eMBB UE uses different transmission modes on different resources.
Preferably, the third transmission method is used for the third transmission resource and the fourth transmission method is used for the fourth transmission resource. Specifically, when the third transmission mode is adopted on the third transmission resource and the fourth transmission mode is adopted on the fourth transmission resource, the third transmission mode and the fourth transmission mode adopt independent coding and modulation. The optional redundancy versions RV transmitted by both are different. Or, the two transmission modes adopt a set of codes, the coded bits are divided into two parts, one part of the bits are mapped to a third transmission resource, and the other part of the bits are mapped to a fourth transmission resource.
Or, optionally, a resource for transmitting the first service type and a scheduling-free resource, that is, a second transmission resource, are defined, a resource whose time domain overlaps but whose frequency domain does not overlap is a sixth transmission resource, and a transmission mode adopted on the sixth transmission resource is a sixth transmission mode. The eMBB UE may employ the following transmission scheme: a third transmission mode is adopted on the third transmission resource, a fifth transmission mode is adopted on the fifth transmission resource, and a sixth transmission mode is adopted on the sixth transmission resource. Specifically, the third, fifth and sixth transmission modes adopt independent coding and modulation. Optionally, redundancy versions RV of at least two transmission modes are different among the three. Or, the three transmission modes adopt a set of codes, and the coded bits are divided into three parts which are respectively mapped to the third, fifth and sixth transmission resources.
Or, optionally, a resource for transmitting the first service type and a scheduling-free resource, that is, a second transmission resource, are defined, a resource in which time domains of the resource and the resource overlap each other is a seventh transmission resource, and a transmission mode adopted on the seventh transmission resource is a seventh transmission mode. The time domain overlapping resources refer to resources in which all time domains are the same and frequency domains are the same or different. The eMBB UE may employ the following transmission scheme: a sixth transmission mode is employed on the sixth transmission resource, and a seventh transmission mode is employed on the seventh transmission resource. Specifically, the sixth and seventh transmission modes adopt independent coding and modulation. The redundancy versions RV of the two alternative transmission modes are different. Or, the two transmission modes adopt a set of codes, and the coded bits are divided into two parts which are respectively mapped to the sixth transmission resource and the seventh transmission resource.
Optionally, the transmission modes are different, and at least one of the following transmission modes is different: modulation scheme, MCS, power control, code resources, etc.
Fifth embodiment
The present embodiment relates to a resource configuration method and a resource relationship.
For the modulation mode adopted by the URLLC UE on the configured resource in the scheduling-free resource, the modulation mode is directly configured by RRC, or activated by the dedicated Downlink Control Information (DCI), until it is activated, it is valid. The modulation scheme used by the eMBB UE in the third transmission resource is notified by the downlink control information.
Optionally, the base station notifies the modulation modes used by the third transmission resource and the fourth transmission resource through two independent DCI domains. Or, the base station notifies the modulation mode in one of the resource regions through a set of independent DCI domains. Optionally, the modulation scheme in another resource region is implicitly obtained. For example, the base station displays and notifies the modulation scheme used in the third transmission resource, and the modulation scheme used in the fourth transmission resource is implicitly obtained from the former, if there is a certain modulation order relationship. Optionally, or, the base station notifies the modulation scheme in the fourth resource region through a set of independent DCI domains, and the modulation scheme used in the third resource is implicitly determined by the modulation scheme configured to the URLLC UE.
Optionally, the base station notifies the modulation modes used by the sixth transmission resource and the seventh transmission resource through two independent DCI domains. Or, the base station notifies the modulation mode in one of the resource regions through a set of independent DCI domains. Optionally, the modulation scheme in another resource region is implicitly obtained.
Optionally, the base station notifies the modulation scheme used by the third transmission resource, the fifth transmission resource, and the sixth transmission resource through three sets of independent DCI domains. Or, the base station notifies the modulation mode in one of the resource regions through a set of independent DCI domains. Optionally, the other two modulation schemes in the resource region are obtained in an implicit manner. Or the base station informs the modulation modes in the two resource areas through two independent DCI areas. Optionally, another modulation method in the resource region is obtained in an implicit manner.
Sixth embodiment
In addition to using different modulation schemes for potentially conflicting resources, the eMBB UE and the URLLC UE may also use different transmit powers, e.g., the power control used by the eMBB UE on at least the third transmission resource is different from the power control used by the URLLC UE on the scheduling-free resource. In addition, the eMBB UE and the URLLC UE may use different code domain resources in terms of resources. Such as using different OCC resources. Fig. 4 and 5 show schematic diagrams of different OCC resources in the overlapping region. As shown in fig. 4, the eMBB UE uses [1, 1] OCC codes on four symbols of the third transmission resource, i.e., transmits the codes in a repeated transmission manner. The URLLC UE uses OCC codes [1, -1] on both symbols of the scheduling free resource. It can be seen that the code length used by the eMBB UE may be different from the code length used by the URLLC UE. The receiving end can correctly demodulate both data using the code sequence. At this time, the eMBB UE and the URLLC UE have no scheduling limitation in the time domain.
In fig. 5, in order to increase the transmission efficiency of the eMBB UE, the time domain symbol length scheduled by the eMBB UE may be limited to an even length, and the time domain symbol length scheduled by the URLLC UE may be limited to an even length. As shown in the figure, transmission of the eMBB UE on the third transmission resource is one unit of two symbols, defined as the first unit. Each first cell is repeated and the data sent in different first cells is different. URLLC also takes two symbols as a unit on the scheduling free resource, defined as second unit, which is repeated in each second unit. And the first cell is aligned with the second cell temporal boundary. That is, only one symbol overlapping between the first unit and the second unit does not occur during scheduling.
Seventh embodiment
Referring to fig. 6, the present embodiment provides a data transmission method, including:
s601, configuring an interception period in scheduling-free transmission resources or transmission resources occupied by at least part of service data to be transmitted;
s602, in the interception period, intercepting the occupation condition of the current channel;
and S603, when the channel is idle, transmitting the service data on the channel.
Optionally, the listening period may specifically include:
the symbols used for listening in the listening period are not used for transmitting uplink data and/or demodulation reference signals DMRS.
Optionally, the symbol of the listening period is a unit transmission symbol of an uplink traffic channel for transmitting the first service type.
Optionally, an interception period is configured in transmission resources occupied by all to-be-transmitted service data, or an interception period is configured in transmission resources occupied by part of to-be-transmitted service data, where the transmission resources occupied by part of to-be-transmitted service data are transmission resources in which all transmission resources occupied by the to-be-transmitted service data conflict with predefined resources.
Optionally, the predefined resource is a transmission resource configured to be free from scheduling.
Optionally, the transmission resource is a time domain transmission symbol.
Optionally, the user listens only when there is data to send during the listening period.
In the licensed assisted access system LAA, a user needs to listen for a period of time before sending data, and if the user finds that data exists in the current channel and is sent, the user does not send the data, and if the channel is idle, the user sends the data. If a UE is listening in the first half of a symbol, the second half of the symbol will send a random signal for preemption, i.e., the entire symbol cannot be used for transmission of valid data. When the eMBB UE sends uplink data, the mode of sending after interception can be adopted to avoid or reduce interference to the URLLC UE.
Specifically, the listening period may be configured within the time domain range of the scheduling free grant free resource, for example, listening every N symbols. The symbols used for sensing cannot be used for transmitting scheduling data, so that sensing symbols are skipped to map corresponding pilot frequency and data transmission on the rest symbols, and the skipped symbols account for the total transmission symbol length, i.e. when sensing symbols are included in the transmission symbols of the scheduling data, the total transmittable symbols become less. Or when the total transmission symbols are not counted, that is, the symbols for scheduling data transmission include the listening symbols, the total transmittable symbols are unchanged but have a delay. Further, whether to count skipped listening symbols into total transmitted symbols depends on at least one of the following factors: if not, whether the delayed symbol is consecutive to the scheduled transmission symbol, or if so, whether the actual code rate of its transmission is above some predetermined threshold.
Optionally, if the listening symbol collides with the scheduled data symbol, the collided data symbol is dropped or transmitted on the nth available symbol after the listening symbol. Preferably, N =1.
Optionally, if the listening symbol collides with a scheduled pilot symbol, the collided pilot symbol is sent on the mth available symbol after the listening symbol. Preferably, M =1.
Optionally, when the transmission symbol of the scheduling data includes the listening symbol, the reference symbol pattern for scheduling transmission is unchanged, or the reference symbol pattern for scheduling transmission is determined at least according to the number of remaining symbols after subtracting the listening symbol.
An embodiment configures a listening period within a scheduling free resource. For example, the scheduling free resource is configured in the first 6 symbols of one slot, and the eMBB UE listens with a listening period of N =3 on the 6 symbols of the scheduling free resource. Further, symbols 0 and 3 are used for listening (assuming 14 symbols in the slot, with an index of 0, 1. If the transmission symbol length of the scheduled eMBB data is 5 symbols, starting with the sign bit 1, the symbols 1,2, 4,5, 6 are occupied. Or the skipped listening symbols are also calculated as transmission symbols of the eMBB, the occupied symbols are 1,2,3,4,5, wherein symbol 3 does not transmit data, please refer to table 1.
TABLE 1
An embodiment configures an interception period in a transmission resource occupied by all service data to be transmitted. Scheduling-free resources are configured on the first M symbols of a slot, and the eMBB UE schedules on the first N symbols within the slot, where N < = M. A listening period with a period of K symbols is configured within the N symbol resources scheduled by the eMBB UE. If N =4,k =2, then listening is performed on symbol 0 and symbol 2.
An embodiment configures a listening period in a transmission resource occupied by a part of service data to be transmitted. The scheduling-free resource is configured in a slot symbol with index i to index j, and the eMBB UE schedules in the slot symbol with index m to index n, wherein m is larger than or equal to i but smaller than or equal to j, and n is larger than or equal to j. A listening period with a period of K symbols is configured within the symbols with index m to index j scheduled by the eMBB UE. If i =0,j =6,m =2,n =8,k =2, a listening configuration with a listening period of 2 symbols is configured within the range of symbol 2 and symbol 6, e.g. listening on symbol 2,4,6.
Optionally, if the listening duration only occupies a part of one symbol, the remaining part may be sent with valid data as follows:
1. higher subcarrier spacing
2. The frequency domain comb mapping structure is a repeating structure in the time domain after IFFT, and one or more repeating units can be transmitted on the rest of the listening symbols.
Optionally, the symbols used for sensing in the sensing period are not used for transmitting uplink data and DMRS, or are used for transmitting only data but not DMRS, or are used for transmitting only DMRS but not data.
Optionally, the uplink traffic channel transmitting the first traffic type is not mapped with a symbol used for listening in the listening period.
Optionally, the intercepted symbol is counted as a transmission symbol of an uplink traffic channel transmitting the first traffic type.
Eighth embodiment
Referring to fig. 7, the data transmission apparatus according to the present embodiment includes:
the data determining module 71 is configured to determine at least two service data to be transmitted, where the service data includes service data of a first service type and/or service data of a second service type;
the data transmission module 72 is configured to transmit the service data according to a preset rule; wherein, the preset rule comprises: the transmission modes of the same service data on different frequency domain resources are different, and/or the transmission modes of different service data are different.
Specifically, the preset rule includes at least one of the following rules:
the first transmission mode is different from the second transmission mode; the transmission mode on the resource for transmitting the first service type is a first transmission mode, and the transmission mode on the resource for transmitting the second service type is a second transmission mode;
the third transmission mode is different from the fourth transmission mode; the third transmission mode is a transmission mode transmitted on a third transmission resource, the third transmission resource is a resource which transmits the first service type and is overlapped with the second transmission resource, and the second transmission resource is a reserved scheduling-free resource configured in a transmission time unit; the fourth transmission mode is a transmission mode transmitted on a fourth transmission resource, and the fourth transmission resource is a non-overlapping resource between a resource for transmitting the first service type and the second transmission resource;
the transmission modes of the transmission resources which are not overlapped in the time domain are different.
The types of the service data are divided into a first service type and a second service type in this embodiment, where the first service type and the second service type may be different service types or the same service type. Specifically, the first service type may be eMBB, the second service type may be URLLC, or both the first service type and the second service type may be eMBB or URLLC.
Referring to fig. 2, fig. 2 shows a schematic configuration of multiple types of transmission resources, where a first transmission resource represents a time-frequency resource in a transmission time unit, a second transmission resource represents a time-frequency resource in the transmission time unit, that is, a reserved scheduling-free resource configured in the first transmission resource, a third transmission resource refers to a resource that transmits a first traffic type and overlaps with the second transmission resource, and a third transmission resource represents a non-overlapping resource between the resource that transmits the first traffic type and the second transmission resource, that is, a resource that transmits the first traffic type, excluding the third transmission resource. In addition, a fifth transmission resource may be further included, where the fifth transmission resource is a resource that transmits the first traffic type and is not overlapped in a time domain with the second transmission resource, that is, a resource that does not collide in the time domain, and whether the resources are overlapped in the frequency domain is not limited.
In this embodiment, the transmission may include at least one of the following rules:
the first transmission mode is different from the second transmission mode; since the first transmission mode is a transmission mode on a resource for transmitting the first service type and the second transmission mode is a transmission mode on a resource for transmitting the second service type, the two transmission modes are different, that is, the transmission modes for respectively transmitting the first service type and the second service type are directly limited to be different. When the service data of the first service type is transmitted, the transmission resource for transmitting the first service type may be split, for example, split into a third transmission resource and a fourth transmission resource, and the fourth transmission resource may also be optionally split into a fifth transmission resource, and so on. That is, the resource for transmitting the first service type may be divided into a plurality of resources, and the transmission modes of the plurality of resources may be different from each other, or may still be the same, and at least one of the plurality of resources is different from the transmission mode of the resource for transmitting the second service type.
The third transmission mode is different from the fourth transmission mode; the third transmission mode and the fourth transmission mode are different in that whether their corresponding transmission resources overlap with the second transmission resources, that is, the reserved scheduling-free resources; for the opposite end, the reserved scheduling-free resource is clear to the opposite end, that is, the second transmission resource is known to the opposite end, but the resource occupied by the actual transmission of the first service type is not implemented according to the reserved scheduling-free resource, so that whether the resource is overlapped with the reserved scheduling-free resource, that is, the respective transmission modes of the third transmission resource and the fourth transmission resource are distinguished to make clear the difference between the two resources and avoid the occurrence of interference.
The transmission modes of the transmission resources which are not overlapped in the time domain are different. The non-overlapping of the time domains means that the two resources are not overlapped on the time domain, that is, the transmission resources are distinguished on the time axis, and if the time domains of the two resources are not overlapped, different transmission modes are adopted for transmission; and if the time domains of the two resources are overlapped, the same transmission mode can be adopted for transmission.
In some embodiments, the difference in transmission modes between the transmission resources whose time domains do not overlap may include:
the third transmission mode and the fifth transmission mode are different; the fifth transmission mode is a transmission mode on a fifth transmission resource, and the fifth transmission resource is a resource which transmits the non-time domain overlapping between the resource of the first service type and the second transmission resource.
In some embodiments, it may further be included that the priority of the second traffic type is greater than the priority of the first traffic type. Because the first service type is generally eMBB, the second service type is URLLC, and the priority requirement of the URLLC is higher, the priority of the second service type is higher because the first service type has a stricter requirement on time delay; of course, the first service type and the second service type may be eMBB or URLLC at the same time.
In some embodiments, the different transmission modes may include: the following configurations for each transmission mode: at least one of constellation Modulation, MCS (Modulation and Coding Scheme), power control, and code resources is different. The Code resource may include an Orthogonal Code OCC (Orthogonal Code).
In some embodiments, the constellation modulation may be different including:

In some embodiments, it may further include: the phase of the constellation modulation adopted by the service data of the first service type and the service data of the second service type in the downlink transmission process is the same; or the like, or a combination thereof,
the constellation modulation adopted by the service data of the first service type and the service data of the second service type in the downlink transmission process meets a first modulation relation.
In some embodiments, it may further include: the first transmission mode is the same as at least one of the third transmission mode, the fourth transmission mode and the fifth transmission mode.
In some embodiments, it may further include: and when the third transmission mode is different from the fourth transmission mode, the redundancy version RV of the third transmission mode is different from that of the fourth transmission mode.

In some embodiments, it may further include: at least two of the sixth transmission mode, the third transmission mode and the fifth transmission mode are different; the sixth transmission mode is a mode of transmitting on a sixth transmission resource, and the sixth transmission resource is a resource that transmits the first traffic type and the second transmission resource, which are overlapped in time domain but not overlapped in frequency domain.
In some embodiments, it may further include: among the sixth transmission mode, the third transmission mode and the fifth transmission mode, at least two of them are different and include:
at least two of the sixth transmission scheme, the third transmission scheme, and the fifth transmission scheme have different redundancy versions RV.
In some embodiments, it may further include: among the sixth transmission mode, the third transmission mode and the fifth transmission mode, at least two of them are different and include:
and the sixth transmission mode, the third transmission mode and the fifth transmission mode adopt the same set of codes, the coded bits are divided into three parts, and the bits of the three parts are respectively mapped to the sixth transmission resource, the third transmission resource and the fifth transmission resource.
In some embodiments, it may further include: the seventh transmission mode is different from the sixth transmission mode; the seventh transmission mode is a transmission mode on a seventh transmission resource, and the seventh transmission resource is a resource for transmitting time domain overlapping between the resource of the first service type and the second transmission resource.

Ninth embodiment
In this embodiment, referring to fig. 8, a data transmission apparatus is provided, including:
an interception configuration module 81, configured to configure an interception period in a transmission resource occupied by service data to be transmitted;

Optionally, the symbol of the listening period is a unit transmission symbol of an uplink traffic channel for transmitting the first service type.
In the licensed assisted access system LAA, a user needs to listen for a period of time before sending data, and if the user finds that data exists in the current channel and is sent, the user does not send the data, and if the channel is idle, the user sends the data. If a UE is listening in the first half of a symbol, the second half of the symbol will send a random signal for preemption, i.e., the entire symbol cannot be used for transmission of valid data. Similarly, when the eMBB UE transmits uplink data, it may adopt a mode of sending after listening to avoid or reduce interference to the URLLC UE.
Specifically, the listening period may be configured in the time domain range of the grant free resource, for example, listening every N symbols. The symbols used for listening will not be available for scheduling the transmission of data, so the listening symbols are skipped from mapping the corresponding pilot and data transmissions on the remaining symbols.
For example, the grant free resource is configured in the first 6 symbols of one slot, and the eMBB UE listens with a listening period of N =3 over the 6 symbols. Further, symbols 0 and 3 are used for listening. If the transmission symbol length of the scheduled eMBB data is 5 symbols, starting with the sign bit 1, the symbols 1,2, 4,5, 6 are occupied. Or the skipped listening symbols are also calculated as transmission symbols of the eMBB, the occupied symbols are 1,2,3,4,5, wherein symbol 3 does not transmit data, please refer to table 1.
Optionally, if the listening duration only occupies a part of one symbol, the remaining part may be sent with valid data as follows:
1. higher subcarrier spacing;
2. the frequency domain comb mapping structure is a repeating structure in the time domain after IFFT change, and one repeating unit can be sent on the remaining half of the symbols.
Optionally, the symbols used for sensing in the sensing period are not used for transmitting uplink data and DMRS, or are used for transmitting data only and not for transmitting DMRS, or are used for transmitting DMRS only and not for transmitting data.
Optionally, the uplink traffic channel transmitting the first traffic type is not mapped with a symbol used for listening in the listening period.
Optionally, the intercepted symbol is counted as a transmission symbol of an uplink traffic channel transmitting the first traffic type.
