图2是根据本申请实施例的无线通信方法200的示意性流程图。如图2所示，该方法200包括以下内容。 FIG. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 2, the method 200 includes the following.

在210中，终端设备接收网络设备发送的下行控制信令，该下行控制信令包括第一信息域和第二信息域。In 210, the terminal device receives downlink control signaling sent by the network device, where the downlink control signaling includes a first information domain and a second information domain.

在220中，从该第一信息域中，该终端设备确定该下行控制信令调度的目标传输块是初次传输还是重复传输。In 220, from the first information domain, the terminal device determines whether the target transport block scheduled by the downlink control signaling is a primary transmission or a repeated transmission.

在一种实现方式中，该第一信息域用于指示该下行控制信令调度的目标传输块的当前传输次数；根据该第一信息域指示的该当前传输次数，该终端设备确定该下行控制信令调度的目标传输块的当前传输是初次传输还是重复传输。In an implementation manner, the first information field is used to indicate a current number of transmissions of the target transport block scheduled by the downlink control signaling; and the terminal device determines the downlink control according to the current number of transmissions indicated by the first information field. Whether the current transmission of the target transport block of the signaling schedule is a primary transmission or a repeated transmission.

例如，该信息域指示当前调度的目标传输块的传输是第1次，则表明当前调度的目标传输块是初次传输，该信息域指示当前调度的目标传输块的传输是大于1的次数，则表明当前调度的目标传输块是重复传输。For example, the information field indicates that the transmission of the currently scheduled target transport block is the first time, indicating that the currently scheduled target transport block is the initial transmission, and the information field indicates that the transmission of the currently scheduled target transport block is greater than one, Indicates that the currently scheduled target transport block is a duplicate transmission.

可选地，传输次数是指针对某一特定数据的枝梢部份数据，加上本次传输，以及之前的传输，总共的次数。Optionally, the number of transmissions is a pointer to a portion of the data for a particular piece of data, plus the current transmission, and the previous transmission, a total number of times.

在一种实现方式中，该第一信息域的取值为0或1；其中，0用于指示该目标传输块为初次传输，1用于指示该目标传输块为重复传输；或，1用于指示该目标传输块为初次传输，0用于该目标传输块为重复传输；根据该第一信息域的取值，该终端设备确定该下行控制信令调度的目标传输块是初次传输还是重复传输。In an implementation manner, the value of the first information field is 0 or 1; where 0 is used to indicate that the target transport block is the initial transmission, and 1 is used to indicate that the target transport block is a repeated transmission; or Instructing the target transport block to be the initial transmission, and 0 for the target transport block to be the repeated transmission; according to the value of the first information field, the terminal device determines whether the target transport block scheduled by the downlink control signaling is the initial transmission or the repetition transmission.

可选地，在该种实现方式中，第一信息域可以是1比特的信息域。Optionally, in this implementation manner, the first information domain may be a 1-bit information domain.

在一种实现方式中，该第一信息域包括第一字段和第二字段；其中，该第一字段用于指示该下行控制信令调度的数据与时域上相邻的上次调度的数据相比是否是新数据，该第二字段用于指示该下行控制信令调度的数据当前传输的次数对n取模后的结果；该终端设备结合该第一字段和该第二字段，确定该下行控制信令调度目标传输块是初次传输还是重复传输。可选地，n＝2。In an implementation manner, the first information field includes a first field and a second field, where the first field is used to indicate data scheduled by the downlink control signaling and last scheduled data adjacent to the time domain. The second field is used to indicate the result of the current transmission of the data scheduled by the downlink control signaling to the modulo of n; the terminal device combines the first field and the second field to determine the The downlink control signaling schedules whether the target transport block is the first transmission or the repeated transmission. Optionally, n=2.

可选地，在本申请实施例中，第一字段可以通过对字段里的值进行翻转指示相比上次调度的数据是新的数据，如果未翻转，则表示相比上次调度的数据不是新的数据。其中，翻转是指从1变为0，或从0变为1。Optionally, in the embodiment of the present application, the first field may indicate that the data in the field is new data compared to the last scheduled data, and if not, the data is not compared to the last scheduled data. New data. Among them, flipping means changing from 1 to 0, or from 0 to 1.

例如，时隙n+1相比于时隙n传输的数据是新的，则可以将第一字段的值从0变为1，时隙n+2相比于时隙n+1传输的数据不是新的，则第一字段的值不变仍为1，时隙n+3相比于时隙n+2传输的数据是新的，则第一字段的值从0变为1。然而，如果时隙n+1的信令被丢失，则终端设备会认为时隙n+2的数据是新的数据，即传输是初次传输，则表明需要从第二信息域获取调制编码等级，然而实际是时隙n+2的数据传输并非是初次传输，而是重复传输，需要从第二信息域获取待重传的编码块。For example, if the data transmitted by slot n+1 compared to slot n is new, the value of the first field can be changed from 0 to 1, and the data transmitted by slot n+2 is compared to slot n+1. If it is not new, the value of the first field remains unchanged at 1, and the data transmitted by slot n+3 compared to slot n+2 is new, then the first field The value changes from 0 to 1. However, if the signaling of the slot n+1 is lost, the terminal device considers that the data of the slot n+2 is new data, that is, the transmission is the initial transmission, indicating that the modulation coding level needs to be obtained from the second information domain. However, the data transmission that is actually the time slot n+2 is not the initial transmission, but is repeated transmission, and the coded block to be retransmitted needs to be acquired from the second information domain.

为了避免该问题的存在，本申请实施例的第一信息域包括第二字段，该第二字段是用于指示该下行控制信令调度的数据当前传输的次数对n取模后的结果。可选地n可以大于等于2。In order to avoid the problem, the first information field of the embodiment of the present application includes a second field, where the second field is used to indicate that the number of current transmissions of the data scheduled by the downlink control signaling is modulo the result of n. Alternatively n can be greater than or equal to 2.

例如，仍如下表1为例，时隙n中第X次传输块A，其第一字段取值为0，时隙n+1中第一次传输传输块B，则第一字段翻转为1，第二字段对2取模后是1，时隙n+2第二次传输传输块B中的至少部分编码块，则第一字段不变为1，第二字段对2取模后是0，如果时隙n+1中的下行控制信令丢失，终端设备结合时隙n+2的第二字段(第一信息域的第一个比特)，该第二字段的取值为0，并非初次传输，因此可以判断为重复传输。For example, as shown in the following Table 1, the Xth transmission block A in slot n has a value of 0 in the first field, and the first transmission slot B in the slot n+1, the first field is flipped to 1 The second field is modulo 1 to 2, and the time slot n+2 transmits at least part of the coding block in the transport block B for the second time, the first field does not change to 1, and the second field is 0 after modulo 2 If the downlink control signaling in the slot n+1 is lost, the terminal device combines the second field of the slot n+2 (the first bit of the first information field), and the value of the second field is 0, not It is transmitted for the first time, so it can be judged as repeated transmission.
