The channel state is determined as the corresponding channel state of the first time-frequency resource group.

It should be understood that the foregoing numerical values are merely exemplary, and the first MCS index and the second MCS index specific values are not limited in the embodiment of the present application.

具体地，终端设备可以根据获得的第一时频资源组相应的信道状态信息和/或预设的第一时频资源组中的第一信息块的目标可靠性确定第二MCS索引。举例来说，终端设备将MCS索引对应的调制编码方案达到第一时频资源组中的第一信息块的目标可靠性所对应的SINR与第一时频资源组相应的信道状态(例如第一时频资源组相应的SINR)比较，选择的第二MCS索引对应的调制编码方案能够达第一时频资源中的第一信息块的目标可靠性所对应的SINR与第一时频资源组相应的SINR最接近。或者，终端设备选择的第二MCS索引是其对应的调制编码方案能够达第一时频资源中的第一信息块的目标可靠性的MCS索引中数值最大的。上述目标可靠性也可是网络设备配置的。Specifically, the terminal device may determine the second MCS index according to the obtained channel state information of the first time-frequency resource group and/or the target reliability of the first information block in the preset first time-frequency resource group. For example, the terminal device determines, by the modulation and coding scheme corresponding to the MCS index, the SINR corresponding to the target reliability of the first information block in the first time-frequency resource group and the channel state corresponding to the first time-frequency resource group (for example, the first Comparing the corresponding SINR of the time-frequency resource group, the modulation coding scheme corresponding to the selected second MCS index can reach the SINR corresponding to the target reliability of the first information block in the first time-frequency resource and the first time-frequency resource group The SINR is the closest.

举例来说，指示ΔMCS的第一信息可以包括2比特，该2比特的4个状态可以分别指示的ΔMCS为，“小于-2”，“-2”，“-1”，“大于或等于0”。在这种情况下，为了提高第一信息块的传输可靠性，其中，“-1”用于指示第二MCS索引相较于第一MCS索引减小1；“-2”用于指示第二MCS索引相较于第一MCS索引减小2；“小于-2”用于指示第二MCS索引相较于第一MCS索引的减小量大于2；“大于或等于0”用于表示第一MCS索引可以达到目标可靠度。For example, the first information indicating ΔMCS may include 2 bits, and the 4 states of the 2 bits may respectively indicate ΔMCS as “less than -2”, “-2”, “-1”, “greater than or equal to 0” ". In this case, in order to improve the transmission reliability of the first information block, where "-1" is used to indicate that the second MCS index is decreased by 1 compared to the first MCS index; "-2" is used to indicate the second The MCS index is reduced by 2 compared to the first MCS index; "less than -2" is used to indicate that the reduction of the second MCS index is greater than 2 compared to the first MCS index; "greater than or equal to 0" is used to indicate the first The MCS index can achieve target reliability.

In this case, in order to balance the transmission reliability and spectral efficiency of the first information block, "less than or equal to -2" is used to indicate that the reduction amount of the second MCS index is greater than or equal to 2 with respect to the first MCS index. "-1" is used to indicate that the second MCS index is reduced by 1 compared to the first MCS index; "0" is used to indicate that the first MCS index can reach the target reliability; "1" is used to indicate the second MCS index phase. Increase by 1 compared to the first MCS index. For example, when ΔMCS is “-1”, the first MCS index is too large, and if the first MCS is 5, then the second MCS will be reduced by 1 compared to the first MCS, that is, the second MCS is 4.

举例来说，如果第一信息包括1比特，如果第一MCS索引对应的调制编码方案能达到的可靠性优于在第一时频资源组上发送的第一信息块的目标可靠性，可以用比特1表示，那么第一参数与第一时频资源组相应的信道状态匹配度为1；如果第一MCS索引对应的调制编码方案能达到的可靠性差于在第一时频资源组上发送的第一信息块的目标可靠性，可以用比特0表示，那么第一参数与第一时频资源组相应的信道状态的匹配度为0。For example, if the first information includes 1 bit, if the reliability of the modulation coding scheme corresponding to the first MCS index can be achieved is better than the target reliability of the first information block sent on the first time-frequency resource group, Bit 1 indicates that the channel state matching degree corresponding to the first time-frequency resource group of the first parameter is 1; if the modulation coding scheme corresponding to the first MCS index can achieve reliability less than that transmitted on the first time-frequency resource group The target reliability of the first information block can be represented by bit 0, and the matching degree of the channel state corresponding to the first parameter and the first time-frequency resource group is 0.

The threshold threshold may be specified by the network device by using high-layer signaling (such as radio resource control signaling) or a communication protocol standard, and the threshold may be 1 dB, 1.5 dB, 2 dB, or the like.

举另外一个例子来说，第一信息包括2个比特，网络设备通过高层信令(例如无线资源控制信令)或者预先约定门限区间，例如第一区间内数值在1dB和2dB之间，第二区间的数值在2dB和3dB之间，第三区间的数值小于或等于1dB，第四区间内的数值大于或等于3dB。终端设备将第一MCS索引对应的调制编码方案达到目标可靠性时对应的SINR与第一时频资源组相应的信道状态(例如第一时频资源组对应的SINR)比较，如果两者之差绝对值小于或等于一个1dB，落入第一区间，终端设备确定采用第一MCS索引够达到第一时频资源组上承载第一信息块的目标可靠性，那么第一参数与第一时频资源组相应的信道状态匹配度为11；如果两者之差的绝对值大于1dB小于2dB，那么第一参数与第一时频资源组相应的信道状态匹配度为10；如果两者之差的绝对值大于2dB小于3dB，那么第一参数与第一时频资源组相应的信道状态匹配度为01；如果两者之差的绝对值大于3dB，那么第一参数与第一时频资源组相应的信道状态匹配度为00。As another example, the first information includes 2 bits, and the network device passes high-level signaling (such as radio resource control signaling) or a predetermined threshold interval, for example, the value in the first interval is between 1 dB and 2 dB, and second. The value of the interval is between 2 dB and 3 dB, the value of the third interval is less than or equal to 1 dB, and the value in the fourth interval is greater than or equal to 3 dB. The terminal device compares the SINR corresponding to the modulation and coding scheme corresponding to the first MCS index to the target reliability, and the channel state corresponding to the first time-frequency resource group (for example, the SINR corresponding to the first time-frequency resource group), if the difference between the two If the absolute value is less than or equal to 1 dB, the terminal device determines that the first MCS index is used to reach the target reliability of the first information block on the first time-frequency resource group, and the first parameter and the first time-frequency The corresponding channel state matching degree of the resource group is 11; if the absolute value of the difference between the two is greater than 1 dB and less than 2 dB, the channel state matching degree corresponding to the first parameter and the first time-frequency resource group is 10; If the absolute value is greater than 2 dB and less than 3 dB, the channel state matching degree corresponding to the first time-frequency resource group is 01; if the absolute value of the difference between the two is greater than 3 dB, the first parameter corresponds to the first time-frequency resource group. The channel state match is 00.

In this case, more specifically, the first information may indicate whether the transmission reliability of the first information block on the first time-frequency resource group satisfies the target reliability, or the first information indicates at least two Whether the transmission reliability of the first information block on the time-frequency resource group satisfies the target reliability, wherein the at least two time-frequency resource groups include the first time-frequency resource group. If the transmission reliability of the first information block on the first time-frequency resource group sent by using the first parameter can meet the target reliability, the channel state corresponding to the first time-frequency resource of the first parameter is a match. If the transmission reliability of the first information block on the first time-frequency resource group sent by using the first parameter cannot meet the target reliability, the channel state corresponding to the first time-frequency resource of the first parameter is a mismatch.

应理解，第三参数可以根据第一信息的指示所述第一时频资源组相应的信道状态确定，或，第三参数也可以根据第一信息指示的所述第一参数与所述第一时频资源组相应的信道状态的匹配度确定，本申请不做限定。It should be understood that the third parameter may be determined according to the channel state corresponding to the first time-frequency resource group of the first information, or the third parameter may also be the first parameter and the first parameter indicated by the first information. The matching degree of the corresponding channel state of the time-frequency resource group is determined, which is not limited in this application.

也就是说，步骤404至406的应用场景是第一控制信息能够调度多个时频资源组(如第一时频资源组和第二时频资源组)的数据传输的情况，在这种情况下，如果终端设备接收网络设备在第一时频资源组上发送的第一信息块后，根据第一控制信息对该第一时频资源组上承载的第一信息块进行解码和译码后，确认译码结果，那么，可选地，将会执行步骤410，所述网络设备接收所述终端设备在所述第一时频资源组上发送的第一信息块的混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息。That is, the application scenario of steps 404 to 406 is a case where the first control information can schedule data transmission of a plurality of time-frequency resource groups (such as the first time-frequency resource group and the second time-frequency resource group), in which case If the terminal device receives the first information block sent by the network device on the first time-frequency resource group, the first information block carried on the first time-frequency resource group is decoded and decoded according to the first control information. And confirming the decoding result, then, optionally, step 410 is performed, the network device receiving a hybrid automatic repeat request of the first information block sent by the terminal device on the first time-frequency resource group ( Hybrid automatic repeat request, HARQ) feedback information.

具体地，该HARQ反馈信息可以为确认应答(acknowledge，ACK)，也可以为不确认应答(not acknowledged，NACK)。Specifically, the HARQ feedback information may be an acknowledgement (ACK) or a non-acknowledgement (not acknowledged, NACK).

在一种情况下，由于URLLC业务的突发性，当待发送第一信息块是URLLC业务数据时，由于信道的时变性，网络设备存储的终端设备上报的信道状态信息已经无法满足该承载在第一时频资源组和第二时频资源组中的第一信息块的高可靠性要求。同时，由于URLLC业务要求极短的传输时延，如果网络设备触发信道状态上报后再调度URLLC数据传输会减少调度第一信息块传输的时间(即减少了第一信息块在URLLC业务时延要求内的最大传输次数)，在URLLC业务的时延要求内达实现第一信息块的正确传输将会比较难。In one case, due to the burstiness of the URLLC service, when the first information block to be sent is the URLLC service data, the channel state information reported by the terminal device stored by the network device cannot satisfy the bearer due to the time variation of the channel. High reliability requirements of the first information block in the first time-frequency resource group and the second time-frequency resource group. At the same time, because the URLLC service requires a very short transmission delay, if the network device triggers the channel state report and then schedules the URLLC data transmission, the time for scheduling the first information block transmission is reduced (that is, the delay requirement of the first information block in the URLLC service is reduced) Within the maximum number of transmissions within the URLLC service, it will be difficult to achieve the correct transmission of the first information block.

网络设备为了在URLLC业务的时延要求内增加传输可靠性，可以一次为终端设备调度大于一次传输。例如，网络设备通过第一控制信息指示终端设备至少在第一时频资源组和第二时频资源组使用第一参数接收第一信息块。由于用于调度URLLC的信道状态信息的不准确，第一时频资源组上的第一信息块的传输不能达到网络设备设定该次调度的目标可靠性的概率较大。如果仅采用HARQ反馈机制，即通过反馈NACK向网络设备指示传输不可靠，终端设备以较大概率对第一时频资源组承载的第一信息块的译码失败，向网络设备发送反馈信息NACK。由于终端设备对第一时频资源组上承载的第一信息块的解调和译码需要一定的时间，当网络设备接收NACK时，网络设备可能已经开始使用第一参数在第二时频资源组发送第一信息块。相应地，终端设备也只能采用第一参数在第二时频资源组上接收第一信息块。这种情况下，终端设备仍会以较大概率对第一信息块译码失败。In order to increase the transmission reliability within the delay requirement of the URLLC service, the network device may schedule the terminal device to be more than one transmission at a time. For example, the network device indicates, by using the first control information, that the terminal device receives the first information block by using the first parameter at least in the first time-frequency resource group and the second time-frequency resource group. Due to the inaccuracy of the channel state information used for scheduling the URLLC, the transmission of the first information block on the first time-frequency resource group cannot reach the probability that the network device sets the target reliability of the scheduling. If only the HARQ feedback mechanism is adopted, that is, the network device is instructed to indicate that the transmission is unreliable by the feedback NACK, the terminal device fails to decode the first information block carried by the first time-frequency resource group with a large probability, and sends a feedback information NACK to the network device. . Since the terminal device needs a certain time to demodulate and decode the first information block carried on the first time-frequency resource group, when the network device receives the NACK, the network device may have started using the first parameter in the second time-frequency resource. The group sends the first information block. Correspondingly, the terminal device can only receive the first information block on the second time-frequency resource group by using the first parameter. In this case, the terminal device still fails to decode the first information block with a large probability.

采用本申请的实施方法，终端设备能够及时向网络设备发送第一信息(例如在对第一时频资源上的第一信息块进行接收的过程中)。网络设备接收终端设备发送的第一信息，并根据第一信息生成第二控制信息，该第二控制信息已经是网络设备基于第一信息进行调整生成的控制信息，这时网络设备向终端设备发送第二控制信息，指示终端设备在第二时频资源组上采用第二参数或者第三参数接收第一信息块，那么对第二时间单元上发送的第一信息块的解码和译码正确的概率将提升，相应地提升业务传输可靠性。With the implementation method of the present application, the terminal device can send the first information to the network device in time (for example, in the process of receiving the first information block on the first time-frequency resource). The network device receives the first information sent by the terminal device, and generates second control information according to the first information, where the second control information is already generated by the network device according to the first information, where the network device sends the control information to the terminal device. a second control information, instructing the terminal device to receive the first information block by using the second parameter or the third parameter on the second time-frequency resource group, and then decoding and decoding the first information block sent on the second time unit is correct The probability will increase, and the reliability of service transmission will be improved accordingly.

具体地，第二控制信息用于调度第二时频资源组中的第一信息块的传输，终端设备能够根据该第二控制信息接收第二时频资源组中的第一信息块，第二控制信息中至少包括第二参数或第三参数；其中，第二参数或第三参数用于终端设备根据该第一参数对第一时频资源组中的第一信息块的进行解码和译码等。第二控制信息指示第三参数时，第三参数中至少包括以下信息中的一种：第二时频资源组中的第一信息块的调制编码方案信息、第二时频资源组中的第一信息块的预编码信息、第二时频资源组中的第一信息块的冗余版本信息等。Specifically, the second control information is used to schedule transmission of the first information block in the second time-frequency resource group, and the terminal device is configured to receive the first information block in the second time-frequency resource group according to the second control information, and second. The control information includes at least a second parameter or a third parameter, where the second parameter or the third parameter is used by the terminal device to decode and decode the first information block in the first time-frequency resource group according to the first parameter. Wait. When the second control information indicates the third parameter, the third parameter includes at least one of the following information: modulation coding scheme information of the first information block in the second time-frequency resource group, and the second time-frequency resource group Precoding information of an information block, redundancy version information of a first information block in a second time-frequency resource group, and the like.

在另外一种情况下，可选地，如果第一控制信息仅用于调度第一时频资源组时频资源组的上第一信息块的传输，那么上述方法还包括步骤407，网络设备生成第三控制信息。网络设备可以根据第一信息生成所述第三控制信息，也可以自己生成所述第三控制信息。In another case, optionally, if the first control information is used to schedule transmission of the first information block of the first time-frequency resource group time-frequency resource group, the method further includes step 407, the network device generates Third control information. The network device may generate the third control information according to the first information, or may generate the third control information by itself.

在所述网络设备接收所述第一信息之后，将执行步骤408，向所述终端设备发送第三控制信息，所述第三控制信息指示在第三时频资源组时频资源组上发送所述第一信息块。After the network device receives the first information, step 408 is performed, and third control information is sent to the terminal device, where the third control information indicates that the third time-frequency resource group is sent on the time-frequency resource group. The first information block is described.

步骤409，网络设备在所述第三时频资源组上发送所述第一信息块。Step 409: The network device sends the first information block on the third time-frequency resource group.

相应地，终端设备根据第三控制信息在第三时频资源组上接收网络设备发送的第一信息块，并根据第三控制信息对第三时频资源组上发送的第一信息块进行解码和译码。Correspondingly, the terminal device receives the first information block sent by the network device on the third time-frequency resource group according to the third control information, and decodes the first information block sent on the third time-frequency resource group according to the third control information. And decoding.

也就是说，步骤407至409的应用场景是第一下行控制信息仅调度第一时频资源组时频资源组的数据传输的情况，在这种情况下，如果终端设备接收网络设备在第一时频资源组上发送的第一信息块后，根据第一控制信息对该第一时频资源组上承载的第一信息块进行解码和译码后，确认译码结果，那么，可选地，将会执行步骤上述410，所述网络设备接收所述终端设备在所述第一时频资源组上发送的第一信息块的混合自动重传请求HARQ反馈信息。That is, the application scenario of steps 407 to 409 is that the first downlink control information only schedules data transmission of the first time-frequency resource group time-frequency resource group, in this case, if the terminal device receives the network device in the first After decoding, decoding, and decoding the first information block carried on the first time-frequency resource group according to the first control information, the first information block sent on the first-time resource group is decoded, and then the decoding result is confirmed. In step 410, the network device receives the hybrid automatic repeat request HARQ feedback information of the first information block sent by the terminal device on the first time-frequency resource group.

具体地，该HARQ反馈信息可以为ACK，也可以为不确认应答NACK。Specifically, the HARQ feedback information may be an ACK or a non-acknowledgment response NACK.

在这种情况下，在URLLC业务的传输过程中，如果仅采用HARQ反馈机制，终端设备以较大概率对第一时频资源组上的第一信息块的译码失败(网络设备存储的该URLLC终端上报的信道状态信息已经无法满足该URLLC下行数据包的高可靠性要求)，终端设备向网络设备发送NACK信息。由于URLLC业务的时延要求是确定的，且终端设备对接收到的第一信息块解调和译码需要一定时间，因此当网络设备接收NACK时，网络设备再次调度第一信息块传输的时间已经不多，在URLLC业务的时延要求内达实现第一信息块的正确传输将会比较难。In this case, in the transmission process of the URLLC service, if only the HARQ feedback mechanism is adopted, the terminal device fails to decode the first information block on the first time-frequency resource group with a large probability (the network device stores the The channel state information reported by the URLLC terminal cannot meet the high reliability requirement of the URLLC downlink data packet, and the terminal device sends the NACK information to the network device. Since the delay requirement of the URLLC service is determined, and the terminal device needs to demodulate and decode the received first information block for a certain time, when the network device receives the NACK, the network device reschedules the transmission time of the first information block. There are not many, it will be difficult to achieve the correct transmission of the first information block in the delay request of the URLLC service.

具体来说，在HARQ反馈信息为NACK时，说明第一时频资源组上发送的第一信息块的译码错误，而由于终端设备对时频资源组上承载的第一信息块的解调和译码需要一定的时间，当网络设备接收NACK的时刻与在第一时频资源组上发送第一信息块的时间间隔T较大，此时如果开始调度对第一信息块的重传，那么与第一信息块的上一次传输之间至少间隔了时间间隔T。Specifically, when the HARQ feedback information is NACK, the decoding error of the first information block sent on the first time-frequency resource group is explained, and the demodulation of the first information block carried by the terminal device on the time-frequency resource group is performed. And decoding requires a certain time, when the network device receives the NACK and the time interval T of transmitting the first information block on the first time-frequency resource group is large, and if the retransmission of the first information block is started, Then at least a time interval T is separated from the last transmission of the first information block.

由于网络设备在接收上述NACK反馈之前，接收终端设备发送的第一信息，假设网络设备接收第一信息的时刻与在第一时频资源组上发送第一信息块的时间间隔为t，那么t<T，网络设备根据该第一信息确定需要对调度第一信息块的重传的，并根据第一信息生成第三控制信息，并使用第三控制信息调度对第一信息块的重传，也就是第三控制信息指示网络设备在第三时频资源组上向发送第一信息块。因此，相比于网络设备接收NACK之后再开始调度对第一信息块的重传，网络设备在接收第一信息后能够及时的调度对第一信息块的重传，因此在第一信息块所述业务的时延要求能，能够增加对第一信息块的重传次数，进而能够提高第一信息块解码和译码正确的概率，提升业务可靠性。The network device receives the first information sent by the terminal device before receiving the NACK feedback, and assumes that the time interval between the time when the network device receives the first information and the time when the first information block is sent on the first time-frequency resource group is t, then t <T, the network device determines, according to the first information, that retransmission of the first information block needs to be scheduled, and generates third control information according to the first information, and schedules retransmission of the first information block by using the third control information, That is, the third control information instructs the network device to send the first information block on the third time-frequency resource group. Therefore, after the network device receives the NACK and then starts scheduling the retransmission of the first information block, the network device can timely retransmit the first information block after receiving the first information, so in the first information block. The delay requirement of the service can increase the number of retransmissions of the first information block, thereby improving the probability of decoding and decoding the first information block and improving service reliability.

应理解，图4描述的实施例中，第一信息块承载的业务可以为URLLC业务，也可以为eMBB业务中的语音业务或者其它对时延较为敏感的eMBB业务，因此，能够满足在低时延的要求下，提高业务传输的可靠性。It should be understood that, in the embodiment described in FIG. 4, the service carried by the first information block may be a URLLC service, or may be a voice service in the eMBB service or other eMBB service sensitive to delay, and thus can meet the low time.
