Technical field

The present application relates to the field of communications and, more particularly, to methods and apparatus for transmitting data.

Background technique

In a Long Term Evolution (LTE) wireless communication system, the transmission of data is based on scheduling. Among them, mainly include dynamic scheduling (Dynamic Scheduling) and semi-persistent scheduling (Semi Persistent Scheduling, SPS) two scheduling methods. For example, in the dynamic scheduling mode, when the uplink device needs to transmit, the terminal device first sends a scheduling request to the network device. After receiving the scheduling request, the network device allocates resources for uplink transmission to the terminal device, and indicates the resource to the terminal device by using physical layer signaling. Subsequently, the terminal device sends uplink data on the resources allocated by the network device for itself. In the SPS scheduling mode, the network device does not indicate the resources used for the uplink transmission to the terminal device every time, but adopts the method of “one allocation, multiple use”. Compared with the dynamic scheduling mode, the SPS scheduling mode saves a lot of signaling overhead.

In the SPS scheduling mode, the terminal device performs SPS data communication according to the SPS scheduling information. The SPS scheduling information includes two parts: a part of the SPS scheduling information is transmitted by Radio Resource Control (RRC) signaling, and the part of the SPS scheduling information includes SPS period information (for example, a parameter semiPersistSchedIntervalDL and/or a parameter semiPersistSchedIntervalUL and an SPS corresponding to the SPS scheduling information. Hybrid Automatic Repeat reQuest (HARQ) process number information (for example, parameter NumberOfConfSPS-Processes and/or parameter NumberOfConfUlSPS-Processes-r13); another part of SPS scheduling information is transmitted through physical layer signaling, this part The SPS scheduling information includes control information for indicating time-frequency resources.

Terminal equipment in the PLMN network, etc.

In order to facilitate the understanding of the embodiments of the present application, first, the related technologies related to the application examples are briefly introduced.

The information can be transmitted through various signalings, wherein different types of signaling (or different types of signaling) have different effective times.

The effective time of signaling can be understood as the time required from the start of signaling to the demodulation of the content included in the signaling.

For example, for physical layer signaling, the effective time of physical layer signaling is considered to be millisecond or shorter than millisecond.

Specifically, the effective time of the physical layer signaling is related to the size of the scheduling unit of the system. For example, the effective time of physical layer signaling can be considered as a scheduling unit of the system.

It should be understood that the scheduling unit in the embodiment of the present application may be a unit of time domain resources that can be scheduled. The scheduling unit can be specified by existing standards. For example, the scheduling unit can be a subframe, a slot, or a mini-slot. The scheduling unit may also be a unit of time domain resources that can be scheduled in the future communication system.

Further, sending the information #1 through the physical layer signaling can be understood as carrying the information #1 in the physical control channel for transmission. For example, the sending the SPS scheduling information by using the physical layer signaling may include sending the SPS scheduling information by using a Physical Downlink Control Channel (PDCCH) and/or an Enhanced Physical Downlink Control Channel (EPDCCH). The physical control channel may also be a downlink control channel in a future communication system such as a 5G communication system.

For example, for medium access control (MAC) signaling (hereinafter referred to as MAC signaling), the effective time of MAC signaling is considered to be millisecond.

It should be noted that although the effective time of the MAC signaling is also in the millisecond level, the effective time of the MAC signaling is the effective time of the physical layer signaling. This is because, in general, the control information sent by the MAC signaling is carried in the service data channel. For example, the SPS scheduling information sent by the MAC signaling can be carried on the Physical Downlink Shared Channel (PDSCH). in. The PDSCH is scheduled by the PDCCH or the EPDCCH. Therefore, if the network device sends the SPS scheduling information by using the MAC signaling, the terminal device needs to detect the PDCCH or the EPDCCH first, and then according to the detected in the PDCCH or the EPDCCH. The control information receives the corresponding PDSCH and completes data demodulation. It should be understood that the PDSCH includes SPS scheduling information. The time required for the process includes the time when the terminal device demodulates the PDCCH or the EPDCCH, and the terminal device demodulates the PDSCH corresponding to the PDCCH or the EPDCCH according to the PDCCH or the EPDCCH, and on the other hand, the effective time of the physical layer signaling, or It is said that if the network device uses the physical layer signaling to send the SPS scheduling information, the terminal only needs to complete the demodulation of the PDCCH or the EPDCCH. Therefore, the MAC signaling is used to send the SPS scheduling information, which is sent relative to the physical layer signaling. The SPS scheduling information increases the time at which the terminal device demodulates the PDSCH. Currently, the effective time of MAC signaling is generally considered to be about 4 milliseconds. However, as the system changes, the effective time of MAC signaling may change. For example, in a system that uses Short Transmission Time Interval (sTTI), the effective time of MAC signaling may be less than 4 milliseconds.

For example, for Radio Resource Control (RRC) signaling (hereinafter referred to as RRC signaling), the effective time of RRC signaling is considered to be 100 milliseconds.

Specifically, the information carried by the RRC signaling has a large load. Therefore, the information carried by the RRC signaling is generally divided into M small packets and carried in the PDSCH for transmission, thereby further increasing the demodulation delay. Therefore, the RRC signaling is performed. The effective time can be considered as the time required for the terminal to demodulate all the content included in the RRC signaling, which is about 100 milliseconds.

In the SPS scheduling mode, the resources of the system (including resources for transmitting uplink data and/or resources for transmitting downlink data) need only be allocated or specified once, and the same resources can be repeatedly used periodically, that is, “once” Assign, use multiple times." The resources of the system are notified through physical layer signaling, and the SPS period is notified by RRC signaling. For downlink and uplink SPS scheduling, the RRC signaling further includes the number of HARQ processes. It should be noted that, in the embodiment of the present application, the downlink refers to the data transmission direction that the network device sends to the terminal device, and the uplink refers to the data transmission direction that the terminal device sends to the network device.

That is to say, in the prior art, the SPS scheduling information used for performing SPS scheduling is divided into two parts, a part of the SPS scheduling information is sent by RRC signaling, and another part of the SPS scheduling information is sent by physical layer signaling. That is, the same type of SPS scheduling information in the prior art is transmitted by only one type of signaling.

For example, in the prior art, as long as the notification of the SPS period is transmitted by using RRC signaling. For another example, as long as the notification of scheduling information such as resource allocation is transmitted by physical layer signaling.

However, with the continuous development of communication technologies, in order to cope with the future explosive mobile data traffic growth, the connection of massive mobile communication devices, and the emerging new services and application scenarios, the delay requirements corresponding to different types of services may be Differently, if the transmission mode of the SPS scheduling information of the prior art is still adopted, the transmission mode performance of the SPS scheduling information is low, which affects the transmission performance.

Based on the above, the present application proposes a method for transmitting data, which can improve the flexibility of transmitting SPS scheduling information, and is advantageous for improving transmission performance.

FIG. 1 is an application scenario diagram applicable to an embodiment of the present application. As shown in FIG. 1, the application scenario includes a network device 101. The application scenario also includes a terminal device 102 located within the coverage of the network device 101. Network device 101 can communicate with terminal device 102. It should be understood that only one terminal device 101 within the coverage of the network device 101 is taken as an example in FIG. Obviously, there may be more terminal devices 101 within the coverage of the network device 101.

The network device in the following embodiments may correspond to the network device 101 in FIG. 1, and the terminal device may correspond to the terminal device 102 in FIG. 1 or a plurality of terminal devices similar to the terminal device 102.

2 is a schematic interaction diagram of an example of a method for transmitting data in accordance with an embodiment of the present application. As shown in FIG. 2, the method can include steps 210-220.

210. The network device sends the first SPS scheduling information by using the first type of signaling. Correspondingly, the terminal device receives the first SPS scheduling information sent by the network device.

The first type of signaling is one of multiple signalings, and each of the multiple signalings can be used to send the first SPS scheduling information.

Optionally, in the embodiment of the present application, multiple signaling may be preset, and each of the multiple signaling may be used to send the first SPS scheduling information. The network device may select the first type of signaling from the plurality of signalings to send the first SPS scheduling information.

Optionally, the network device can store the plurality of signaling. For example, the network device may store a set of the multiple signalings {Signaling#1,...,Signaling#N}, where N≥2, Signaling#x is a type of signaling, and different types of signaling are correspondingly effective. The time is different. For example, the effective time of signaling in the set can satisfy the following relationship:

Signalling#1<...<Signalling#N

As an optional example, the multiple signaling may include at least two of physical layer signaling, MAC signaling, and RRC signaling. The effective time of the physical layer signaling <the effective time of the MAC signaling <the effective time of the RRC signaling. Optionally, the plurality of signalings may also include other types of signaling. For example, Radio Link Control (RLC) signaling may also be included. Alternatively, the RLC signaling may replace the MAC signaling in the above.

The multiple SPS scheduling information includes the physical layer signaling, the MAC signaling, and the RRC signaling. The first SPS scheduling information includes an SPS periodicity information, and the three types of signaling may be used to send the SPS periodic information, where the network device may Among the three types of signaling, some type of signaling (for example, MAC signaling) is selected as the first type signaling to transmit the SPS period information.

The network device sends data to the terminal device according to the first SPS scheduling information, or the network device receives data from the terminal device according to the first SPS scheduling information; correspondingly, the terminal device according to the The first SPS scheduling information receives data from the network device, or the terminal device transmits data to the network device according to the first SPS scheduling information.

It should be understood that, in the embodiment of the present application, if the first SPS scheduling information is for downlink data transmission, the network device may send downlink data according to the first SPS scheduling information. If the first SPS scheduling information is for uplink data transmission, the network device may receive uplink data according to the first SPS scheduling information. For the manner in which the terminal device performs data transmission with the network device according to the first SPS scheduling information, refer to the foregoing description, which is not described herein for brevity.

Compared with the prior art, for one SPS scheduling information (for example, SPS period information) can only be transmitted through a fixed type of signaling, in the present application, multiple signaling can be used to transmit the first SPS scheduling information. Therefore, the network device may select the first type of signaling from the multiple types of signaling to send the first SPS scheduling information according to an actual situation, and the transmission of the first SPS scheduling information has high flexibility, which is beneficial to improving transmission performance. .

It can be seen from the above that in the prior art, the SPS scheduling information includes two parts, wherein a part of the SPS scheduling information is transmitted through RRC signaling. For convenience of description, the part of the SPS scheduling information may be recorded as “SPS scheduling information #A”. . It should be understood that the SPS scheduling information #A can be understood as SPS scheduling information that is notified by the LTE system through RRC signaling in the prior art. Specifically, the SPS scheduling information #A includes SPS cycle information, HARQ number information, and the like. Another part of the SPS scheduling information is transmitted through the physical layer signaling. For convenience of description, the part of the SPS scheduling information may be referred to as “SPS scheduling information #B”. The SPS scheduling information #B may be understood as LTE in the prior art. The SPS scheduling information notified by the system through physical layer signaling. Specifically, the SPS scheduling information #B includes control information for indicating a time-frequency resource. Taking the LTE system as an example, the SPS scheduling information #B may include at least one of the following control information: cross-carrier indication information used for multi-carrier scheduling; and used to distinguish downlink control information (Downlink Control Information, DCI) format 0 And DCI format 1A indication information, where DCI format 0 is mainly used for scheduling uplink data, DCI format 1A is used for scheduling downlink data; frequency hopping flag; resource allocation and frequency hopping resource allocation (Resource block assignment and Hopping resource allocation) and so on. The transmission mode of the prior art SPS scheduling information is less flexible and easily affects the performance of data transmission.

On the one hand, since the effective time of the RRC signaling is 100 milliseconds, in the prior art, the SPS scheduling information #A is always sent through the RRC signaling, which causes the system to fail to achieve fast adaptation and affect the delay of data scheduling. If the service feature changes and the service requires a short delay, the transmission mode of the SPS scheduling information of the prior art cannot meet the requirement of the service delay, thereby affecting the transmission performance.

For example, it is assumed that the delay requirement of the communication service #1 is 10 ms. In the prior art, the network device sends the SPS scheduling information #A corresponding to the communication service #1 to the terminal device through RRC signaling, and the terminal device only after one hundred milliseconds. The SPS scheduling information #A can be obtained, so that the delay of the terminal device processing the to-be-communicated service #1 is long, which affects the transmission performance.

Based on this, as an optional example, in the 210:

The first SPS scheduling information may include SPS scheduling information #A, and the multiple signaling may be used to send the SPS scheduling information #A.

Specifically, in the embodiment of the present application, the network device can flexibly determine the signaling sending manner corresponding to the SPS scheduling information #A, as compared with the prior art, where the network device always sends the SPS scheduling information #A through the RRC signaling. For example, in some cases, the network device may send SPS scheduling information #A through MAC signaling, and in some cases, the network device may also send SPS scheduling information #A through RRC signaling. This solution is beneficial to reduce the impact of delay on data transmission of communication services.

Further, in the 210:

The first SPS scheduling information may include at least part of the SPS scheduling information #A.

As an alternative example, multiple signaling may be used to transmit a portion of the SPS scheduling information in the SPS scheduling information #A. Another part of the SPS scheduling information in the SPS scheduling information #A is still transmitted using RRC signaling.

For example, if the first type of signaling is MAC signaling, the network device sends an SPS period through MAC signaling, and the network device still uses the RRC signaling to send the HARQ quantity information.

As an alternative to another example, multiple signaling may be used to transmit all SPS scheduling information in SPS scheduling information #A.

The network device may select at least part of the SPS scheduling information in the SPS scheduling information #A from the plurality of types of signaling, which is beneficial to reducing the impact of the delay on the data transmission of the communication service, and is beneficial to improving the efficiency of data transmission.

On the other hand, the overhead of the control channel is a very important factor in measuring the efficiency of data transmission. It is very important to use the control channel reasonably. In the prior art, the SPS scheduling information #B is transmitted through physical layer signaling, which easily leads to unnecessary use of the physical downlink control channel.

For example, it is assumed that the delay requirement of the to-be-communicated service #1 is 10 ms. In the prior art, the network device transmits the SPS scheduling information #B through physical layer signaling. The terminal device can acquire the SPS scheduling information #B in one scheduling unit. In fact, the delay requirement of the to-be-communicated service #1 is 10 ms, and it is not necessary for the network device to use the physical layer signaling to transmit the SPS scheduling information #B, which may easily lead to unreasonable control of the channel usage.

Based on this, as an optional example, in the 210:

The first SPS scheduling information may include SPS scheduling information #B, and the multiple signaling may be used to send the SPS scheduling information #B.

Specifically, in the embodiment of the present application, the network device can flexibly determine the signaling sending manner corresponding to the SPS scheduling information #B, as compared with the prior art, where the network device always sends the SPS scheduling information #B through the physical layer signaling. For example, in some cases, the network device may send SPS scheduling information #B through MAC signaling, and in some cases, the network device may also send SPS scheduling information #B through RRC signaling. This scheme facilitates the rational use of the control channel and helps to reduce the control channel overhead.

Further, in the 210:

The first SPS scheduling information may include at least part of the SPS scheduling information #B.

As an optional example, multiple signaling may be used to transmit a portion of the SPS scheduling information in the SPS scheduling information #B. Another part of the SPS scheduling information in the SPS scheduling information #B is still transmitted using physical layer signaling.

For example, assuming that the first type of signaling is MAC signaling, the network device sends control information for indicating time-frequency resources through MAC signaling, and the network device still uses the physical layer signaling to send the SPS scheduling information #B in addition to the indication. The rest of the information other than the control information of the frequency resource.

As an alternative to another example, multiple signaling may be used to transmit all SPS scheduling information in SPS scheduling information #B.

The network device may select at least part of the SPS scheduling information in the SPS scheduling information #B from the plurality of types of signaling, which is beneficial to reasonably using the control channel, and is beneficial to reducing the control channel overhead.

It should be noted that the first SPS scheduling information sent by the network device by using the first type signaling may include at least one of the foregoing multiple situations. For example, the first SPS scheduling information may include at least partial SPS scheduling information #A and/or at least partial SPS scheduling information #B. The SPS scheduling information that is sent by the first type of signaling, which is specifically included in the first type of signaling, may be flexibly set according to the actual situation.

It can be seen from the above that in the embodiment of the present application, the same type of SPS scheduling information can be sent by using different types of signaling. Optionally, the method 200 may further include:

The network device sends the second SPS scheduling information by using the second type of signaling; correspondingly, the terminal device receives the second SPS scheduling information that is sent by the network device by using the second type of signaling.

The second SPS scheduling information and the first SPS scheduling information are the same type of first SPS scheduling information (or the second SPS scheduling information and the first SPS scheduling information include the same type of SPS scheduling information).

For example, the second SPS scheduling information and the first SPS scheduling information both include an SPS period. For another example, the second SPS scheduling information and the first SPS scheduling information both include control information for indicating a time-frequency resource, and for example, the second SPS scheduling information and the first SPS scheduling information both include a hybrid automatic retransmission corresponding to the SPS. The number of HARQ information.

Optionally, the first SPS scheduling information and the second SPS scheduling information correspond to different services (for scheduling different services of the terminal device). The different services may be different types of services. For example, the first SPS scheduling information corresponds to an enhanced mobile broadband eMBB (eMBB) service, and the second SPS scheduling information corresponds to a URLLC service. The different services can also be different services of the same type. For example, the first SPS scheduling information and the second SPS scheduling information are both corresponding to the URLLC service, where the first SPS process corresponds to the in-vehicle service, and the second SPS process corresponds to the remote control or the industrial automation service.

Optionally, the time when the network device sends the first SPS scheduling information is located before the time when the network device sends the second SPS scheduling information, where the first SPS scheduling information may be used by the network device and the terminal device to perform data transmission in the first time period, where The second SPS scheduling information may be used by the network device and the terminal device to perform data transmission during the second time period.

The second type of signaling is one of the foregoing multiple types of signaling, and the second type of signaling is different from the first type of signaling.

In the above, it is described that the network device can send the first SPS scheduling information by using the first type of signaling, which is beneficial to improving the efficiency of data transmission. Optionally, the first type of signaling (or the second type of signaling described above) may be related to a service to be communicated. For example, the network device can determine the first type of signaling according to the service to be communicated. Further optionally, the first type of signaling may be determined according to at least one of the following manners.

Way #1

As an optional example, the first type of signaling may be related to a delay requirement of a service to be communicated. For example, the 201 can include:

The network device determines the first type of signaling according to the delay requirement of the to-be-communicated service.

Specifically, the different communication services may correspond to different delay requirements, and the network device may determine the first type of signaling according to the delay requirement of the service to be communicated. The network device can obtain the delay requirement in multiple manners according to the transmission type of the service to be communicated (the transmission type includes uplink transmission or downlink transmission).

For example, if the transmission type of the to-be-communicated service is the uplink transmission, the network device may receive the indication information sent by the terminal device or the radio access network (RAN), and the indication information may be used to indicate the delay requirement. The RAN can be understood as a device that can be used to control a network device. For example, the RAN may be a Mobility Management Entity (MME) device, which is not limited herein.

For example, if the transmission type of the to-be-communicated service is downlink transmission, the network device may acquire the delay requirement of the to-be-communicated service or acquire the delay requirement through the RAN.

The determining, by the network device, the first type of signaling may include at least the following situations according to the delay requirement of the to-be-communicated service:

Situation #1

The signaling type of the network device determining that the effective time meets the delay requirement of the service to be communicated is the first type of signaling.

Specifically, in the multiple signaling, there is a signaling type that satisfies the delay requirement of the service to be communicated, and at this time, the network device may select signaling that meets the delay requirement. That is to say, the effective time of the first type of signaling satisfies the delay requirement of the service to be communicated.

Further, assuming that the effective time of at least two signalings of the multiple signalings meets the delay requirement, the network device may randomly select a signaling that meets a delay requirement, and the network device may further determine the at least two types. The signaling with the longest effective time in the signaling is the first type of signaling, that is, if at least two of the multiple signalings meet the delay requirement of the to-be-communicated service, the first type of signaling is The signaling with the longest effective time in at least two types of signaling is described. The advantage of selecting the signaling with the longest effective time from the at least two types of signaling is that the signaling overhead of physical layer control signaling or MAC layer control signaling can be saved.

For example, it is assumed that the multiple signaling includes RRC signaling, MAC signaling, and physical layer signaling.

The delay requirement of the communication service #1 is 10 ms, and the MAC signaling and the effective time of the physical layer signaling satisfy the delay requirement, and the network device can determine the first type of the first SPS scheduling information of the to-be-communicated service #1. The signaling is MAC signaling to save the overhead of physical layer signaling.

The delay requirement of the communication service #2 is 200 ms, and the foregoing three types of signaling all meet the delay requirement of the to-be-communicated service #2, and the network device can determine that the RRC signaling is the first type of signaling, so as to save the MAC signaling. And the overhead of physical layer signaling.

Situation #2

And determining that the signaling with the shortest effective time in the multiple signaling is the first type signaling, if the signaling type that meets the delay requirement is not found in the multiple signaling.

That is to say, in the multiple signaling, there is no signaling type that satisfies the delay requirement of the service to be communicated. In this case, the network device can select the signaling with the shortest effective time.

For example, it is assumed that the plurality of signaling includes RRC signaling and MAC signaling. The delay requirement of the communication service #3 is 2 ms, and the effective time of the MAC signaling is about 4 ms, which does not satisfy the delay requirement of the communication service #3. The network device can determine that the MAC signaling is the first type of signaling. In this case, although the method of the embodiment of the present application cannot meet the delay requirement of the service to be communicated, compared with the prior art, the delay of the service to be communicated can be reduced, thereby reducing the delay in processing the communication service due to the delay. Impact.

Way #2

As an alternative example, the first type of signaling may be related to the type of service of the service to be communicated. For example, the 201 can include:

The network device determines the first type of signaling according to the service type of the to-be-communicated service.

Optionally, the network device may store a correspondence between a service type and a signaling type of the service to be communicated. Optionally, the to-be-communicated service in the embodiment of the present application may be an (Ultra-Reliable and Low Latency Communications, URLLC) service. The URLLC service includes a variety of services. For example, the URLLC service includes in-vehicle services, remote control or industrial automation services, and video services. The signaling corresponding to different types of URLLC services may be different. For example, if the service to be communicated is an in-vehicle service, the corresponding signaling type is physical layer signaling. For example, if the to-be-communicated service is an extreme industrial control service, the corresponding signaling type may be physical layer signaling; for example, if the to-be-communicated service is remote control or industrial automation, the corresponding signaling type is MAC signaling. For example, if the service to be communicated is a video service, the corresponding signaling type is RRC signaling.

It should be understood that the method for obtaining the service type of the network device can be referred to the related description of the delay requirement, which is not described here for brevity.

It should also be understood that the manner in which the network device enumerated above determines the first type of signaling is only an example, and the network device may further determine the first type of signaling by other means. For example, if the to-be-communicated service is an uplink service, the terminal device may also send signaling information to the network device, where the signaling information is used to indicate the first type of signaling that the terminal device desires.

In the embodiment of the present application, the network device may select the first type of signaling for the first SPS scheduling information of the to-be-communicated service according to the to-be-communicated service. On the one hand, if the first SPS scheduling information includes the SPS scheduling information #A, the impact of the delay on the transmission service transmission data can be reduced; on the other hand, if the first SPS scheduling information includes the SPS scheduling information #B, the control can be enabled. The channel is reasonably utilized. That is, in the embodiment of the present application, in different situations (for example, for different to-be-communicated services), the same type of SPS scheduling information may be different according to the first type of signaling, which can improve the flexibility of the network device to transmit SPS scheduling information. Conducive to improve data transmission performance.

The above describes an example of a method for transmitting data according to the present application, which can improve the flexibility of a network device to transmit SPS scheduling information, and is advantageous for improving system transmission performance. Hereinafter, another example of the method for transmitting data of the present application, which can improve the accuracy of data transmission, will be described.

3 is a schematic interaction diagram of another example of a method for transmitting data in accordance with the present application. As shown in FIG. 3, the method can include steps 310-330.

The network device sends the index information, where the index information is used by the terminal device to determine an index of the HARQ process corresponding to each SPS process in the at least two SPS processes; correspondingly, the terminal device receives the index information.

Specifically, the network device may allocate multiple SPS processes to the terminal device. The multiple SPS processes may correspond to multiple services of the terminal device. The multiple services may be different types of services. For example, if the terminal device supports the enhanced mobile broadband eMBB service and the URLLC service, the different SPS processes may correspond to different types of services, for example, the first SPS process corresponds to the eMBB service, and the second The SPS process corresponds to the URLLC service. The multiple services may also be different services in the same type. For example, the first SPS process and the second SPS process both correspond to the URLLC service, where the first SPS process corresponds to the in-vehicle service, and the second SPS process corresponds to the remote control or the industrial automation service.

Optionally, the index information may explicitly or implicitly indicate an index of a HARQ process corresponding to each SPS process in the at least two SPS processes.

For example, the index information may directly indicate an index of a HARQ process corresponding to each SPS process. For another example, the index information may be used to indicate a starting index of a HARQ process corresponding to each SPS process and a number of HARQ processes included in each SPS process, and the terminal device may be based on a starting index of the HARQ process and each SPS. The number of HARQ processes included in the process determines the index of the HARQ process included in each SPS process.

320. The network device performs data transmission with the terminal device according to the index information (or the network device according to an index of a HARQ process corresponding to each SPS process in the at least two SPS processes) (that is, sends data to the terminal device or receives the data from the terminal device. Correspondingly, the terminal device performs data transmission with the network device according to the index information (or the index of the HARQ process corresponding to each SPS process in the at least two SPS processes) (ie, receiving the data from the network device) Data or send data to a network device).

It should be noted that, in the embodiment of the present application, the network device performs data transmission with the terminal device according to the index information, or the terminal device performs data transmission with the network device according to the index information, which may be understood as: the network device and the terminal device. The HARQ process index corresponding to the data transmission is determined according to the index information, that is, the network device and the terminal device perform data transmission according to the HARQ process index determined by the index information.

In the embodiment of the present application, the network device may determine a plurality of SPS processes for the terminal device, and indicate the HARQ process corresponding to each SPS process in the multiple SPS processes to the terminal device by using the index information, so as to facilitate the terminal device and the network device. Data transmission for multiple SPS processes is possible. For example, different URLLC services also have different delay requirements. For a terminal device, if there are URLLC services with different requirements for delay, then different SPS processes can be used for URLLC services with different delay requirements. . This solution can improve the efficiency of data transmission.

Optionally, the method 300 of the embodiment of the present application may be applied to asynchronous HARQ.

Further, in the prior art, the network device configures a unique SPS process for the terminal device, and the starting index of the HARQ process corresponding to the unique SPS process is “0”. In the embodiment of the present application, the network device may configure multiple SPS processes for the terminal device, if the starting index of the HARQ process corresponding to each SPS process in the multiple SPS processes is “0”, the multiple SPS processes correspond to The HARQ process may collide.

FIG. 4 is a schematic configuration diagram showing an example of a collision of a HARQ process. As shown in FIG. 4, it is assumed that the terminal device is configured with the first SPS process and the second SPS process, and the first SPS process corresponds to two HARQ processes, and the second SPS process corresponds to three HARQ processes. The method for determining the index of the HARQ process according to the prior art is that the indexes of the two SPQ processes corresponding to the two HARQ processes are 0 and 1, respectively, and the indexes of the two SPS processes corresponding to the three HARQ processes are 0, 1, and 2, respectively. It is assumed that the terminal device sends the SPS uplink data to the network device, and the network device performs feedback according to the SPS uplink data. For example, the network device feeds back an Acknowledgement (ACK) or a Negative Acknowledgement (NACK). The feedback may explicitly carry the HARQ process index, and assume that the index of the HARQ process carried in the ACK fed back by the network device is 0. After receiving the ACK, the terminal device cannot determine that the ACK is for the HARQ index in the first SPS process. The feedback of 0 is also the feedback of the HARQ index of 0 in the second SPS process, which affects data transmission.

Based on this, the embodiment of the present application may be used to solve the problem that a HARQ process corresponding to multiple SPS processes collides with at least one of the following two manners.

Way #1

As an optional example, the network device may determine an index of the HARQ process corresponding to each SPS process in the at least two SPS processes, and the index of the HARQ process corresponding to any two SPS processes in the at least two SPS processes does not overlap, and the network device And transmitting index information according to an index of the HARQ process corresponding to each SPS process in the at least two SPS processes; correspondingly, the terminal device receives the index information, and determining, according to the index information, that each SPS process in the at least two SPS processes corresponds to The index of the HARQ process does not overlap with the index of the HARQ process corresponding to any two SPS processes in the at least two SPS processes.

FIG. 5 is a schematic diagram of still another example of a method for transmitting data according to an embodiment of the present application. As shown in FIG. 5, it is assumed that the terminal device corresponds to the first SPS process and the second SPS process, and the first SPS process corresponds to two HARQ processes, and the second SPS process corresponds to three HARQ processes. The indexes of the two SPS processes corresponding to the two HARQ processes are 0 and 1, respectively, and the indexes of the two SPS processes corresponding to the two HARQ processes are 2, 3, and 4, respectively, and the index and the HARQ process corresponding to the first SPS process. The indexes of the HARQ processes corresponding to the two SPS processes do not overlap.

Optionally, the index of the HARQ process can satisfy the following formula:

HARQ Process ID=HARQ-start-Process ID+[floor(CURRENT_TTI/semiPersistSchedInterval)]modulo numberOfConfSPS-Processes

The HARQ process ID is the index of the HARQ process corresponding to the configured SPS process, the HARQ-start-Process ID is the starting index of the HARQ process corresponding to the configured SPS process, and the floor (X) indicates the rounding down of X, CURRENT_TTI The location of the time unit in which the SPS is transmitted, semiPersistSchedInterval is the SPS period (which can correspond to the SPS period of the downlink service, and can also correspond to the SPS period of the uplink service), and Y modulo Z indicates that the remainder function, that is, Y modulo Z, is divided by Y. The remainder after Z, numberOfConfSPS-Processes is the number of HARQ processes configured for the SPS.

For example, two SPS processes are used between the network device and the terminal device for data transmission. It is assumed that the first SPS process includes two HARQ processes, the starting index of the HARQ process corresponding to the first SPS process is 0 (ie, HARQ-start-Process ID=0), the SPS period of the first SPS process is 10 ms, and the network device And the terminal device performs data transmission according to the HARQ process included in the first SPS process according to 0, 10ms, 20ms, 30ms, etc. (that is, data transmission according to a 10ms pattern pattern), assuming that the current CURRENT_TTI is located at 20ms, floor(CURRENT_TTI/semiPersistSchedInterval)=floor (20/10)=2, because the first SPS process includes two HARQ processes, namely numberOfConfSPS-Processes=2, so floor(CURRENT_TTI/semiPersistSchedInterval)]modulo numberOfConfSPS-Processes=0, that is, when CURRENT_TTI corresponds to 20ms, The index of the HARQ process corresponding to the SPS data generated in the CURRENT_TTI is 0. If the current CURRENT_TTI is located at 20 ms, according to the above method, the index of the HARQ process corresponding to the SPS data generated in the CURRENT_TTI is 1. On the other hand, it is assumed that the second SPS process includes three HARQ processes, the start index of the HARQ process corresponding to the second SPS process is 2 (ie, HARQ-start-Process ID=2), and the SPS cycle of the second SPS process is also 10ms, but the network device and the terminal device use the HARQ process included in the second SPS process for data transmission according to 5ms, 15ms, 25ms, 35ms, etc., assuming that the current CURRENT_TTI is located at 15ms, floor(CURRENT_TTI/semiPersistSchedInterval)=floor(15/ 10)=1, because the second SPS process includes three HARQ processes, namely numberOfConfSPS-Processes=3, so floor(CURRENT_TTI/semiPersistSchedInterval)]modulo numberOfConfSPS-Processes=1, that is, when CURRENT_TTI corresponds to 15ms, in the CURRENT_TTI The index of the HARQ process corresponding to the generated SPS data is 3. According to the foregoing calculation method, it can be known that when the CURRENT_TTI corresponds to 25 ms, the index of the HARQ process corresponding to the SPS data generated in the CURRENT_TTI is 4, and when the CURRENT_TTI corresponds to 35 ms, the CURRENT_TTI The index of the HARQ process corresponding to the generated SPS data is 2. Therefore, it can be observed that, in the method of the embodiment of the present application, the indexes of the HARQ processes included in different SPS processes are different from each other, so that the problem of collision of HARQ processes corresponding to multiple SPS processes does not occur.

It should be noted that the following data transmission is taken as an example. If the total number of the HARQ processes for performing downlink data transmission between the network device and the terminal device is limited, in the embodiment of the present application, the index of the HARQ process may also be adopted. The following formula determines:

HARQ Process ID={HARQ-start-Process ID+[floor(CURRENT_TTI/semiPersistSchedInterval)]modulo numberOfConfSPS-Processes}modulo M,

Wherein, M represents the maximum number of HARQ processes that can be supported by the network device and the terminal device for downlink data transmission, or represents the maximum HARQ process that can be supported between the network device and the terminal device for downlink SPS data transmission. Number. The above determination manner is also effective for uplink data transmission between the network device and the terminal device. In this case, M can represent the maximum number of HARQ processes that can be supported between the network device and the terminal device for uplink data transmission, or represent the network. The maximum number of HARQ processes that can be supported between the device and the terminal device for uplink SPS data transmission.

In addition, optionally, in the embodiment of the present application, the starting indexes of the HARQ processes corresponding to the two SPS processes in the at least two SPS processes (assumed to be represented by the first SPS process and the second SPS process) satisfy the following relationship: HARQ-start-Process ID (first SPS process) + numberOfConfSPS-Processes (first SPS process) = HARQ-start-Process ID (second SPS process), where HARQ-start-Process ID (first SPS process) Indicates the starting index of the HARQ process corresponding to the first SPS process, numberOfConfSPS-Processes (the first SPS process) indicates the number of HARQ processes corresponding to the first SPS process, and the HARQ-start-Process ID (the second SPS process) indicates the second SPS The starting index of the HARQ process corresponding to the process. Further optionally, if considering the maximum number of HARQ processes that can be supported between the network device and the terminal device or the maximum number of HARQ processes for SPS transmission, the two SPS processes in the at least two SPS processes correspond to The starting index of the HARQ process satisfies the following relationship: {HARQ-start-Process ID (first SPS process) + numberOfConfSPS-Processes (first SPS process)} modulo M=HARQ-start-Process ID (second SPS process), Where M represents the maximum number of HARQ processes that can be supported between the network device and the terminal device for downlink data transmission, or represents the maximum HARQ process that can be supported between the network device and the terminal device for downlink SPS data transmission. The number, or the maximum number of HARQ processes that can be supported between the network device and the terminal device for uplink data transmission, or the maximum HARQ process that can be supported between the network device and the terminal device for uplink SPS data transmission. Number.

It should be noted that, in this manner, the index information may include a starting index of the HARQ process included in each SPS process, and the number of the HARQ processes. Optionally, the index information may further include a period of each SPS process, and the terminal device Based on the index information, the index of the HARQ process included in each SPS process may be determined by using the above formula.

Way #2

As an optional example, the network device may determine an SPS process index corresponding to each SPS process in the at least two SPS processes and an index of the HARQ process included in each SPS process, and the network device may be configured according to the SPS process corresponding to each SPS process. The index and the index of the HARQ process included in each SPS process send index information; correspondingly, the terminal device receives the index information, and determines, according to the index information, an SPS process index corresponding to each SPS process and each SPS process includes The index of the HARQ process.

Optionally, the index information may include an SPS process index corresponding to each SPS process, and a number of HARQ processes included in each SPS process. Optionally, the index information may further include a period of each SPS process. The terminal device may determine the HARQ process index corresponding to the HARQ process included in each SPS process according to the following formula, and combine the SPS process index to distinguish the HARQ processes included in the different SPS processes.

HARQ Process ID=[floor(CURRENT_TTI/semiPersistSchedInterval)]modulo numberOfConfSPS-Processes

For a detailed description of the parameters in the formula, refer to the related description above, and for brevity, it will not be described here.

Optionally, numberOfConfSPS-Processes may also be the number of HARQ processes included in the SPS process including the HARQ process.

For example, still taking FIG. 4 as an example, assuming that two SPS processes are supported between the network device and the terminal device, in order to identify the HARQ process index included in different SPS processes, an SPS process index may be introduced to distinguish different SPS processes. When the terminal device transmits the SPS uplink data, the network device may feed back the SPS process identifier when the ACK/NACK is fed back. For example, the terminal device may be used to indicate the SPS process by using one bit. After receiving the feedback information, the terminal device may determine the SPS process identifier according to the SPS process identifier. The feedback information is used to feedback the first SPS process or the second SPS process for solving the problem that the HARQ process sends a collision.

In the above, it is described that the network device may send index information to the terminal device for the terminal device to determine an index of the HARQ process corresponding to the at least two SPS processes. Optionally, in the embodiment of the present application, the network device may send the index information in multiple manners.

Way #1

As an optional example, the network device may use a certain type of signaling to transmit the index information. That is to say, as long as the index information is transmitted by using the type signaling, the type signaling may be RRC signaling, MAC signaling or physical layer signaling. Taking RRC signaling as an example, the network device always sends index information through RRC signaling.

Way 2#

As an alternative to another example, each of the plurality of signalings can be used to transmit the index information. Optionally, the index information may include a plurality of sub-information corresponding to the plurality of SPS processes, and each of the sub-information is used by the terminal device to determine an index of the HARQ process corresponding to the SPS process corresponding to the sub-information. For example, the i-th (i≥1) sub-information corresponds to the i-th SPS process, and the i-th sub-information is used by the terminal device to determine an index of the HARQ process corresponding to the i SPS processes. The signaling for transmitting the plurality of sub-informations may include two cases:

Situation #1

The plurality of sub-information is transmitted by one type of signaling (eg, first type signaling)

1a. The multiple sub-information is carried in one control signaling.

That is, the network device transmits a plurality of sub-information (ie, index information) through one control signaling. The network device may determine the signaling type corresponding to the multiple sub-information according to the actual situation, and send the multiple sub-information by using one control signaling (for example, a first type signaling) corresponding to the signaling type. For example, in some cases, the network device may send the multiple sub-information using one RRC signaling. In some cases, the network device can send the multiple sub-information using one MAC signaling.

2a. The multiple sub-information is carried in multiple control signaling.

Specifically, the network device sends multiple sub-information through multiple control signaling. Optionally, the multiple pieces of control signaling are in one-to-one correspondence with multiple pieces of sub-information. The network device may determine the signaling type corresponding to the multiple sub-information according to the actual situation, and send the multiple sub-information correspondingly by using multiple signaling corresponding to the signaling type. For example, in some cases, the network device sends N pieces of sub-information in a one-to-one correspondence using N RRC signaling. In some cases, the network device sends N pieces of sub-information in a one-to-one correspondence using N pieces of MAC signaling.

That is, in case #1, it is assumed that at least two types of signaling include RRC signaling, MAC signaling, and physical layer signaling. The network device may send the index information through RRC signaling in a certain situation, and in some cases, the index information is sent through the MAC signaling, and in some cases, the index information is sent through the physical layer signaling.

Based on the case #1, optionally, in the above method 200, the 210 may include:

The network device sends the first SPS scheduling information by using the first type of signaling; correspondingly, the terminal device receives the first SPS scheduling information that is sent by the network device by using the first type of signaling.

The first SPS scheduling information includes index information, and the index information is used by the terminal device to determine an index of the HARQ process corresponding to each SPS process in the at least two SPS processes. It should be understood that the index information may be sent through one control signaling or through multiple control signaling.

Situation #2

The plurality of sub-information is transmitted by at least one signaling.

Specifically, the network device may determine a signaling type corresponding to each sub-information, and send the corresponding sub-information using the determined signaling type. For example, the network device may determine the signaling type corresponding to the first sub-information, and may determine the signaling type corresponding to the second sub-information, where the signaling type corresponding to the first sub-information and the signaling type corresponding to the second sub-information may be The same may be used, wherein the first sub-information is used by the terminal device to determine an index of the HARQ process corresponding to the first SPS process, and the second sub-information is used by the terminal device to determine an index of the HARQ process corresponding to the second SPS process.

That is, in case #2, it is assumed that at least two types of signaling include RRC signaling, MAC signaling, and physical layer signaling, and the network device may pass at least one of RRC signaling, MAC signaling, and physical layer signaling. Send index information.

Based on case #2, optionally, in the above method 200, the 210 may include:

The network device may send the first SPS scheduling information by using the first control signaling. Correspondingly, the terminal device receives the first SPS scheduling information that is sent by the network device by using the first control signaling, where the first control signaling is the first type of signaling. make;

The first SPS scheduling information that is sent by using the first control signaling includes a first sub-information, where the first sub-information is used by the terminal device to determine an index of the HARQ process corresponding to the first SPS process. Optionally, the first SPS scheduling information sent by using the first control signaling may be SPS scheduling information corresponding to the first SPS process.

The method 200 can also include:
