Detailed ways

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

According to an aspect of the embodiments of the present invention, a service data transmission method is provided, which is applied to the base station side, as shown in FIG. 1 , and specifically includes the following steps:

Step 11: According to the transmission performance index of the target service, respectively determine the numerical configuration Numerology information of the target service, the maximum number of transmission times of the service data of the target service, and the redundancy version used for each transmission.

Wherein, the target service mainly refers to the URLLC service, and the transmission performance index refers to a parameter index that can characterize the transmission performance required by the target service, such as reliability and delay. Aspects are explained. According to the reliability and delay requirements of the currently occurring URLLC service, determine the corresponding numerical configuration information, the maximum number of transmission times for transmitting the URLLC service, and the redundancy version used in each transmission. Among them, the reliability requirements and delay requirements of different service types in URLLC services are different, and the numerical configuration information is used to configure the frequency domain of URLLC services to meet the delay requirements of URLLC services, and the maximum number of transmissions is used to ensure URLLC The reliability requirements of the business, while ensuring the reliability requirements of the URLLC business, the transmission delay can be further reduced by configuring the redundant version of each transmission.

Step 12: within the maximum number of transmissions, use the redundancy version corresponding to each transmission, and send the service data to the terminal through the transmission resources corresponding to the numerical configuration information.

After the base station determines the corresponding numerical configuration information, the maximum number of transmissions, and the redundancy version used for each transmission according to the transmission performance index of the URLLC service, within the maximum number of transmissions, the redundancy version corresponding to each transmission is used, and the value is passed. The transmission resource corresponding to the configuration information sends the service data of the URLLC service to the terminal. For example, the base station determines the value configuration information of the URLLC service according to the reliability and delay requirements of the URLLC service. The terminal performs four service data transmissions, and the redundancy version used for each transmission is the same. Further, the base station carries the service data conforming to the above configuration in the transmission resource mapped by the numerical configuration information for transmission.

Further, as shown in Figure 2, step 11 specifically includes the following steps:

Step 21: Determine the numerical configuration information of the target service according to the transmission performance index of the target service.

Wherein, the numerical configuration information includes: subcarrier spacing, cyclic prefix (CP, Cyclic Prefix) length and frequency band information. Wherein, different CP lengths can be configured when the value configuration is the same, and the CP is used to eliminate interference between symbols and channels. Wherein, when a shorter CP length is configured, the symbol length can be shortened to further reduce the transmission delay.

Specifically, step 21 may include the following scenarios: if the transmission performance indicator of the target service is the first transmission performance indicator, determine the first numerical configuration information of the target service; if the transmission performance indicator of the target service is the second transmission performance indicator, determine the target The second value configuration information of the service. Wherein, the time delay required by the second transmission performance index is lower than the time delay required by the first transmission performance index, and the subcarrier spacing corresponding to the second numerical configuration information is greater than the subcarrier spacing corresponding to the first numerical configuration information. It means that the base station configures different subcarrier spacing and frequency band information according to the delay requirements of different services. The larger the configured subcarrier spacing, the smaller the required delay, which can meet services with lower delay requirements. Specifically, the configuration of subcarrier spacing and frequency band information needs to satisfy the division of numerical configurations.

Step 22: According to the transmission performance index of the target service, determine the maximum number of transmission times of the service data of the target service and the redundancy version used for each transmission.

Wherein, the redundancy version includes: a self-decodable first redundancy version and/or a non-self-decodable second redundancy version. Among them, the self-decodable first redundant version can be decoded independently, the non-self-decodable second redundant version needs to be combined with the first redundant version to be able to decode, and the non-self-decodable second redundant version cannot be decoded independently Implement decoding. Further, the first redundancy version includes a plurality of different redundancy versions, the second redundancy version includes a plurality of different redundancy versions, and the self-decodable first redundancy version RVa∈{RVa0, RVa1, RVa2, RVa3 , ... }, non-self-decodable second redundant version RVb ∈ {RVb0, RVb1, RVb2, RVb3, ...}. Among them, the first redundant version is mostly used for initial transmission, and the second redundant version is used for retransmission, so the second redundant version can use a redundant version with a smaller data length than the first redundant version, which is beneficial to the terminal Quickly decode, combine data, and feed back response information.

Specifically, step 22 can be implemented with reference to the following steps: according to the transmission performance index of the target business, determine that the number of transmissions of the first redundancy version used by the business data of the target business is M, and the transmission times of the second redundancy version used by the business data The number of times is N. Among them, the sum of M and N is the maximum number of transmissions of business data, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 0; and the redundancy version used for the first transmission is the first redundancy Version.

Specifically, from the perspective of URLLC service transmission reliability, for a UE, the base station can perform multiple transmissions for one transmission block TB to ensure service data transmission reliability. For example, according to the reliability requirements of the target business that occurs, it is determined that the maximum number of transmissions of the business data of the target business is 4 times (that is, M+N=4), wherein the self-decodable first transmission is used in these 4 transmissions. A redundant version, ie M=4, N=0. Wherein, the self-decodable first redundancy version includes two transmission modes, one is multiple transmissions of the same redundancy version, and the other is multiple transmissions of different redundancy versions. As shown in Figure 3, these 4 transmissions use the same redundancy version in the first redundancy version for transmission, such as RVa0, or, as shown in Figure 4, the self-decodable first redundancy version is used in these 4 transmissions Different redundancy versions RVa0, RVa1, RVa2 and RVa3 are transmitted. Wherein, it is worth pointing out that the first redundancy version is used for the initial transmission, that is, the redundancy version used in the first transmission among the multiple transmissions is the first redundancy version, specifically RVa0.

The above enumerates the embodiment in which the first redundancy version is used for multiple transmissions, and the following embodiment will introduce the scenario of mixed transmission using the first redundancy version and the second redundancy version in multiple transmissions. For example: according to the reliability requirements of the target business, it is determined that the maximum number of transmissions of the business data of the target business is 4 times (that is, M+N=4), wherein, among the 4 transmissions, the first two transmissions use self-decoding The first redundant version of , and the second redundant version that is not self-decodable is used in the last two transmissions, that is, M=2, N=2. Wherein, as shown in FIG. 5 , among the four transmissions, the first two transmissions use the first redundancy versions RVa0 and RVa1 for transmission, and the last two transmissions use the second redundancy versions RVb1 and RVb2 for transmission. Among them, since the data length of the second redundancy version is smaller than the data length of the first redundancy version, in order to further reduce the transmission delay and improve the utilization of transmission resources, cascade transmission can be used between different redundancy versions, as shown in the figure As shown in 6, the starting positions of the frequency domain resources of the first redundant version used in the first two transmissions in the four transmissions are the same, and the second redundant version used in the last two transmissions can be transmitted in a cascaded manner. That is, after the second redundancy version RVb1 used in the third transmission is transmitted, the transmission of the second redundancy version RVb2 used in the fourth transmission can start from the end position of the transmission of RVb1. Among them, it is worth pointing out that when the first redundant version and the second redundant version are jointly used for multiple transmissions, the first redundant version can be used for transmission in the first M transmissions, and after the M transmissions are completed, then In the next N transmissions, the second redundancy version is used for transmission, that is, the first redundancy version and the second redundancy version are transmitted sequentially. Alternatively, after the first transmission is performed using the first redundancy version, the second redundancy version and the first redundancy version are transmitted alternately, that is, the first redundancy version and the second redundancy version are not transmitted in strict order .

Further, before the above step 12, the following steps may also be included: determine the configuration indication information according to the determined numerical configuration information, the maximum number of transmission times, and the redundancy version used for each transmission; send the configuration indication information to the receiving target Terminal for business.

Specifically, in order to save the transmission resource overhead of the control information and reduce the signaling overhead of configuring the indication information, according to the determined numerical configuration information, the maximum number of transmissions, and the redundancy version used for each transmission, determine the step of configuring the indication information, It can be realized by referring to the following method: according to the preset numerical configuration information, the maximum number of transmissions, and the mapping relationship between the redundant version used for each transmission and the configuration indication information, determine the currently determined numerical configuration information, the maximum number of transmissions, and the number of times each transmission Configuration instructions corresponding to the adopted redundancy version. Specifically, the base station can determine the corresponding numerical configuration information, the maximum number of transmission times, and the redundancy version information used for each transmission according to the transmission performance index of the target service that occurs. After determining the above parameters, the base station needs to send the configuration instruction information to the terminal. , in order to reduce the signaling overhead of configuration indication information, the mapping relationship between numerical configuration information, the maximum number of transmissions, and the redundancy version used for each transmission and configuration indication information can be established in advance on the base station side, as shown in the following table:

Wherein, X in the table is a transmission parameter of reliability, such as: the maximum number of transmissions and the redundancy version used for each transmission, X=F(M: {RVa}; N: {RVb}). Among them, M is the number of transmissions of the first redundancy version, {RVa} is the specific redundancy version used for each transmission in M transmissions, such as RVa1, RVa2, RVa3...etc.; N is the transmission of the second redundancy version times, {RVb} is the specific redundancy version used for each transmission in the N transmissions, such as RVb1, RVb2, RVb3...etc. Y in the table is a configuration parameter of time delay, specifically including: subcarrier spacing and frequency band information, Y=F(SCS, F). Wherein, SCS is configured subcarrier spacing, and F is frequency band information. Wherein, Y further includes CP length information, wherein configuring a shorter CP length can shorten the symbol length in the time domain and further reduce the time delay. Further, each combination of X1, X2, ..., and Y1, Y2, ... corresponds to a configuration indication information, so that the number of bits of the configuration indication information can be greatly reduced. For example, the base station side predefines If there are 32 transmission modes Pattern, only 5 bits of configuration indication information is needed to notify the UE of the specific transmission configuration adopted by the current target service.

Further, after the base station determines the configuration indication information of the target service, it can inform the terminal through semi-static configuration or dynamic configuration. Specifically, the base station may send the configuration indication information to the terminal through high-layer signaling, downlink control signaling of a common control channel, or downlink control signaling of a dedicated downlink control channel. For example, for semi-static configuration, the configuration indication information can be configured by high-level signaling, and for semi-static configuration, it can also be sent to the UE by a similar common control channel. In particular, the configuration of M and N can also be dynamically indicated by downlink control signaling according to the channel condition of the UE.

Optionally, for the redundant version of the configuration, the frequency domain positions of multiple retransmissions can be determined by configuration or dynamic indication. Only the starting position of the initial transmission is indicated. When the starting position of the preconfigured retransmission resource is the same as that of the initial transmission, and the TB size is 1/2 of the initial transmission, the indication method shown in Figure 7 can be used. If it is not considered whether the initial transmission and the retransmission satisfy the preset relationship, the manner of indicating the initial transmission and the retransmission as shown in FIG. 8 may be adopted.

Further, the base station sends configuration indication information to the terminal through the control channel. Specifically, the relationship between the control channel and the data channel includes the following multiple methods: the method of frequency division multiplexing of the control channel and the data channel as shown in FIG. 9 , such as The mode of time-division multiplexing between the control channel and the data channel shown in Figure 10, the mode of setting its own control channel in each sub-channel as shown in Figure 11, and the mode of nesting the control channel in the data channel as shown in Figure 12 .

Further, after step 12, the service data transmission method of the embodiment of the present invention further includes the following steps: receiving the response information fed back by the terminal after correctly receiving the service data; if the response information is received, then stop sending the service data to the terminal; if If the response information is not received, the redundant version corresponding to the next transmission is used to send the service data to the terminal until the maximum number of transmissions is reached or the response information fed back by the terminal is received. This means that in order to further reduce the delay and save system transmission resources, after the base station transmits business data according to the determined numerical configuration information, the maximum number of transmissions, and the redundancy version used for each transmission, it can further receive the correct reception of the terminal. Response information fed back after receiving business data. After receiving the response information, the base station stops sending the currently transmitted service data to the terminal; otherwise, it uses the redundancy version corresponding to the next transmission to continue sending the currently transmitted service data to the terminal until the maximum number of transmissions is reached or terminal feedback is received response information.

Specifically, when the terminal does not receive service data, it does not feed back ACK information to the base station, and the base station cannot receive the ACK feedback information, then it will continue to repeatedly send the service data to the terminal until the ACK feedback information is received or the maximum number of transmissions is reached. After correctly receiving the service data, the terminal sends ACK feedback information to the base station, so that the base station stops sending service data under current transmission according to the ACK feedback information, so as to save network transmission resources.

In the service data transmission method of the embodiment of the present invention, the base station determines its numerical configuration information according to the transmission performance index of the target service that occurs, so as to ensure the delay requirement of service transmission; and further determines its maximum transmission times according to the transmission performance index of the target service And the redundancy version used for each transmission to ensure the reliability of business data transmission.

The above embodiment introduces the service data transmission method of the present invention from the base station side, and the following embodiment will further introduce the service data transmission method on the terminal side with reference to the accompanying drawings.

As shown in FIG. 16, the service data transmission method of the embodiment of the present invention is applied to the terminal side, and specifically includes the following steps:

Step 161: The receiving base station configures Numerology information, the maximum number of service data transmissions and the redundancy version used for each transmission according to the numerical values determined and sent by the transmission performance index of the target service.

Wherein, the target service mainly refers to the URLLC service, and the transmission performance index refers to a parameter index that can represent the transmission performance required by the target service.

For the mapping relationship, for example, 32 transmission patterns are predefined on the base station side, so only 5-bit configuration indication information is needed to notify the UE of the specific transmission configuration adopted by the target service.

After the base station determines the configuration instruction information of the target service, it can inform the terminal through semi-static configuration or dynamic configuration. Specifically, the step of receiving the configuration indication information determined and sent by the base station according to the transmission performance index of the currently occurring business includes: through high-level signaling, downlink control signaling of a common control channel, or downlink dedicated control signaling of a dedicated downlink control channel, The configuration indication information determined and sent by the base station according to the transmission performance index of the target service is received. For example, for semi-static configuration, the configuration indication information can be configured by high-level signaling, and for semi-static configuration, it can also be sent to the UE by a similar common control channel. In particular, the configuration of M and N can also be dynamically indicated by downlink control signaling according to the channel condition of the UE.

Step 162: Within the maximum number of transmissions, use the redundancy version corresponding to each transmission, and receive service data through the transmission resources corresponding to the numerical configuration information.

When receiving the base station according to the reliability and delay requirements of the URLLC service, determine the numerical configuration information of the URLLC service, the maximum number of transmissions of service data is 4 times, and each transmission uses the same redundancy version for transmission, then the base station can transmit at most The service data is transmitted to the terminal 4 times, and the redundancy version used for each transmission is the same. Further, the base station carries the service data conforming to the above configuration in the transmission resource mapped by the numerical configuration information for transmission. Correspondingly, after learning the above numerical configuration information, the maximum number of transmission times, and the adopted redundancy version information, the terminal receives and decodes downlink data in corresponding transmission resources to obtain corresponding service data.

After step 162, the service data transmission method further includes: if the service data is received correctly, feeding back response information to the base station, and stopping receiving or directly discarding subsequent service data.

In order to further reduce the delay and save system transmission resources, after receiving the service data correctly, the terminal sends an ACK feedback information to the base station, so that the base station stops sending the service data under current transmission according to the ACK feedback information, so as to save network transmission resources . However, because there is a scenario where the terminal sends ACK feedback information, but the base station does not receive the ACK feedback information, the base station will also send service data to the terminal. At this time, since the terminal has correctly received this part of service data, in order to save terminal processing resources, The terminal may stop receiving subsequent service data, or directly discard the received subsequent service data.

In the service data transmission method of the embodiment of the present invention, the terminal receives the numerical configuration information determined and sent by the base station according to the transmission performance index of the target service to ensure the delay requirement of service transmission; and further receives the base station according to the transmission of the target service Performance indicators determine and send the maximum number of transmissions of business data and the redundancy version used for each transmission to ensure the reliability of business data transmission.
