Description

通信方法和通信装置Communication method and communication device

技术领域Technical field

本申请涉及通信领域，并且更具体地，涉及通信领域中通信方法和通信装置。This application relates to the communication field, and more specifically, to a communication method and communication device in the communication field.

背景技术Background technique

在无线通信***中，控制信息的作用非常重要。两个通信设备之间通过控制信息可以实现信息的交互，实现一个通信设备对另一个通信设备的控制。以基站和用户设备为例，在下行通信过程中，基站向终端设备发送下行控制信息(downlink control information，DCI)，下行控制信息用于调度数据信道或者传输块(transport block，TB)，为了降低DCI的开销，节省传输资源，可以采用一个DCI调度多个传输块，当DCI调度的传输块越多，则DCI中需要较多的比特来指示不同的传输块，或者不同的传输块的传输状态等，这样会导致DCI的开销比较大，导致***的传输性能较差。In wireless communication systems, the role of control information is very important. Two communication devices can realize information interaction through control information, and realize the control of one communication device to another communication device. Take the base station and user equipment as examples. In the downlink communication process, the base station sends downlink control information (DCI) to the terminal equipment. The downlink control information is used to schedule data channels or transport blocks (TB). The overhead of DCI saves transmission resources. One DCI can be used to schedule multiple transmission blocks. When DCI schedules more transmission blocks, more bits are required in DCI to indicate different transmission blocks or the transmission status of different transmission blocks. And so on, this will cause the DCI overhead to be relatively large, resulting in poor transmission performance of the system.

其中，S220至少包括两种实现方式：Among them, S220 includes at least two implementation modes:

第一种实现方式，第一设备根据DCI先确定第一窄带内的第一资源块数量，或者，根据DCI先确定第一窄带内的第一资源块数量以及资源块的起始位置；然后第一设备根据第一资源块数量以及下行控制信息确定第一重复次数。In the first implementation manner, the first device first determines the number of first resource blocks in the first narrowband according to DCI, or first determines the number of first resource blocks in the first narrowband and the start position of the resource blocks according to DCI; A device determines the first number of repetitions according to the number of the first resource blocks and the downlink control information.

具体来说，下行控制信息包括第一信息和第二信息，第一信息用于指示资源块起始位置，或者，第一信息用于指示第一资源块数量，或者第一信息用于指示资源块起始位置和第一资源块数据，第二信息用于在第一重复次数集合中确定第一重复次数；若第一信息指示资源块起始位置，则第一设备可以根据第一信息确定资源块的起始位置，若第一信息指示第一资源块数量，则第一设备可以根据第一信息确定第一资源块数量，若第一信息指示资源块起始位置和第一资源块数量，则第一设备根据第一信息确定第一资源块数量和资源块起始位置。Specifically, the downlink control information includes first information and second information. The first information is used to indicate the starting position of the resource block, or the first information is used to indicate the number of the first resource block, or the first information is used to indicate the resource. The block start position and the first resource block data, the second information is used to determine the first repetition number in the first set of repetition times; if the first information indicates the start position of the resource block, the first device can determine according to the first information The starting position of the resource block. If the first information indicates the first resource block quantity, the first device may determine the first resource block quantity according to the first information. If the first information indicates the resource block starting position and the first resource block quantity , The first device determines the number of the first resource block and the starting position of the resource block according to the first information.

当第一设备确定第一资源块数量之后，第一设备可以根据第一资源块数量确定第一资源块数量所在的第一资源块数量集合，由于第一资源块数量与第一重复次数集合对应，则第一设备可以根据第一资源块数量集合确定第一重复次数集合，第二信息是用于第一设备在第一重复次数集合中确定第一重复次数的，例如，第二信息可以指示第一重复次数在第一重复次数集合中的次序，这样第一设备就可以确定第一重复次数。After the first device determines the first resource block quantity, the first device may determine the first resource block quantity set in which the first resource block quantity is located according to the first resource block quantity, because the first resource block quantity corresponds to the first repetition quantity set , The first device may determine the first set of repetition times according to the first set of resource block numbers, and the second information is used by the first device to determine the first repetition times in the first set of repetition times. For example, the second information may indicate The order of the first repetition number in the first repetition number set, so that the first device can determine the first repetition number.

在第一种实现方式中，对于覆盖等级较好的终端设备，例如，第一设备为覆盖增强等级0，或者为覆盖增强等级1，或者为覆盖增强模式A的终端设备，第一信息和第二信息共包含的比特数为4或5，即仅利用4比特或者5比特就可以指示资源块起始位置和/或第一资源块数量以及第一重复次数，从而可以节省DCI的开销。对于覆盖等级较差的终端设备，例如第一设备为覆盖增强等级2，或者为覆盖增强等级3，或者为覆盖增强模式B的终端设备，第一信息和第二信息共包含的比特数为1或2或3。即仅利用1比特或者1比特或者3比特就可以指示资源块起始位置和/或第一资源块数量以及第一重复次数，从而可以节省DCI的开销。In the first implementation manner, for a terminal device with a better coverage level, for example, the first device is coverage enhancement level 0, or coverage enhancement level 1, or coverage enhancement mode A terminal device, the first information and the first information The total number of bits included in the two pieces of information is 4 or 5. That is, only 4 bits or 5 bits can be used to indicate the starting position of the resource block and/or the first resource block number and the first repetition number, thereby saving the overhead of the DCI. For a terminal device with a poor coverage level, for example, the first device is coverage enhancement level 2, or coverage enhancement level 3, or coverage enhancement mode B terminal equipment, the number of bits contained in the first information and the second information is 1 Or 2 or 3. That is, only 1 bit or 1 bit or 3 bits can be used to indicate the starting position of the resource block and/or the number of the first resource block and the first number of repetitions, thereby saving the overhead of the DCI.

因此，在本申请实施例中，资源块数量集合存在对应的重复次数集合，通过资源块数量集合与重复次数集合的关联关系可以降低DCI的开销，例如，利用DCI中的1比特指示第一资源块数量，第一设备确定第一资源块数量之后就可以确定第一资源块数量集合，第一设备可以根据第一资源块数量集合确定第一重复次数集合，再利用DCI中的1比特指示第一重复次数在第一重复次数集合中的次序，从而第一设备可以在第一重复次数集合中确定第一重复次数，从而可以有效的减少DCI的开销。Therefore, in the embodiment of the present application, the resource block quantity set has a corresponding repetition number set, and the DCI overhead can be reduced through the association between the resource block quantity set and the repetition number set. For example, one bit in the DCI is used to indicate the first resource The first device can determine the first resource block number set after determining the first resource block number. The first device can determine the first set of repetition times according to the first resource block number set, and then use 1 bit in the DCI to indicate the first set of repetitions. An order of the number of repetitions in the first set of repetitions, so that the first device can determine the first number of repetitions in the first set of repetitions, thereby effectively reducing the overhead of the DCI.

即在第一种实现方式中，可以是分别指示，利用第一信息指示第一资源块数量，利用第二信息确定在第一重复次数集合中的第一重复次数，能够有效的降低DCI的开销。That is, in the first implementation manner, it can be separately indicated, the first information is used to indicate the number of the first resource block, and the second information is used to determine the first repetition number in the first repetition number set, which can effectively reduce the DCI overhead .

第二种实现方式，下行控制信息包括第三信息，第三信息用于指示第一资源块数量和第一重复次数，或，第三信息用于指示资源块起始位置、第一资源块数量和第一重复次数。第一设备根据第三信息确定第一资源块数量和第一重复次数，或者，第一设备根据第三信息确定第一资源块数量、资源块的起始位置以及第一重复次数。In the second implementation manner, the downlink control information includes third information, and the third information is used to indicate the number of first resource blocks and the first number of repetitions, or the third information is used to indicate the starting position of the resource block and the number of first resource blocks And the first number of repetitions. The first device determines the number of first resource blocks and the first number of repetitions according to the third information, or the first device determines the number of first resource blocks, the starting position of the resource block, and the first number of repetitions according to the third information.

在一种可能的实现方式中，多个资源块数量集合至少包括第二资源块数量集合和第三资源块数量集合(这里的第二资源块数量集合或第三资源块数量集合可以是前述的第一资源块数量集合)，且第二资源块数量集合包含的任一元素值都小于第三资源块个数集合包含的任一元素值；第二资源块数量集合所关联的第二重复次数集合包含P个元素，第三资源块数量集合所关联的第三重复次数集合包含Q个元素，其中P小于或等于Q，P和Q为大于0的正整数。举例来说，第二资源块数量集合为{4,6}，{4,6}关联的重复次数集合包括4个元素，第三资源块数量集合为{2}，{2}关联的重复次数集合包括2个元素。对于下行传输，功率不受限制，资源块数量越多则有可能信道质量越差，或者为了提升鲁棒性有可能资源块数量也越多，当资源块数量较多时，重复次数集合包括的元素越多，则重复次数能够选择范围就越大，相反地，资源块数量越小，表示当前的信道质量越好，重复次数集合包括的元素就越少，则重复次数能够选择范围就越小，通过这种方式能够节省DCI的开销。In a possible implementation manner, the multiple resource block quantity sets include at least a second resource block quantity set and a third resource block quantity set (here the second resource block quantity set or the third resource block quantity set may be the aforementioned The first resource block quantity set), and any element value contained in the second resource block quantity set is less than any element value contained in the third resource block quantity set; the second number of repetitions associated with the second resource block quantity set The set contains P elements, and the third set of repetition times associated with the third resource block quantity set contains Q elements, where P is less than or equal to Q, and P and Q are positive integers greater than 0. For example, the second resource block quantity set is {4,6}, the {4,6} associated repetition number set includes 4 elements, and the third resource block quantity set is {2}, {2} associated repetition number The set includes 2 elements. For downlink transmission, the power is not limited. The greater the number of resource blocks, the worse the channel quality, or the greater the number of resource blocks to improve robustness. When the number of resource blocks is large, the set of elements included in the number of repetitions The more the number of repetitions is, the larger the range of repetition times can be selected. Conversely, the smaller the number of resource blocks, the better the current channel quality. The fewer elements included in the repetition number set, the smaller the range of repetition times can be selected. In this way, the overhead of DCI can be saved.

在第一种实现方式中，对于覆盖等级较好的终端设备，例如，第一设备为覆盖增强等级0，或者为覆盖增强等级1，或者为覆盖增强模式A的终端设备，第三信息共包含的比特数为4或5，即仅利用4比特或者5比特就可以指示资源块起始位置和/或第一资源块数量以及第一重复次数，从而可以节省DCI的开销。对于覆盖等级较差的终端设备，例如第一设备为覆盖增强等级2，或者为覆盖增强等级3，或者为覆盖增强模式B的终端设备，第三信息共包含的比特数为1或2或3。即仅利用1比特或者1比特或者3比特就可以指示资源块起始位置和/或第一资源块数量以及第一重复次数，从而可以节省DCI的开销。In the first implementation manner, for terminal devices with better coverage levels, for example, the first device is coverage enhancement level 0, or coverage enhancement level 1, or coverage enhancement mode A terminal devices, and the third information includes The number of bits in is 4 or 5, that is, only 4 bits or 5 bits can be used to indicate the starting position of the resource block and/or the first resource block number and the first repetition number, thereby saving the overhead of DCI. For terminal devices with poor coverage levels, for example, the first device is coverage enhancement level 2, or coverage enhancement level 3, or coverage enhancement mode B terminal equipment, the number of bits contained in the third information is 1 or 2 or 3. . That is, only 1 bit or 1 bit or 3 bits can be used to indicate the starting position of the resource block and/or the first resource block quantity and the first repetition number, thereby saving the overhead of DCI.

在上面的两种实现方式中，第一设备为覆盖增强等级0，或者为覆盖增强等级1，或者为覆盖增强模式A的终端设备，根据下行控制信息确定的第一资源块数量为{1,2,3,4,5,6}真子集中的元素，例如，第一资源块数量为{1,2,4,6}中的一个元素等。例如，第一重复次数为数据信道的重复次数。第一重复次数可以为{n1,n2,n3,n4}中的元素，n1，n2，n3，n4为正整数。In the above two implementations, the first device is coverage enhancement level 0, or coverage enhancement level 1, or coverage enhancement mode A terminal device, and the first resource block number determined according to the downlink control information is {1, 2,3,4,5,6} elements in the proper subset, for example, the number of the first resource block is one element in {1,2,4,6}, etc. For example, the first number of repetitions is the number of repetitions of the data channel. The first number of repetitions may be elements in {n1, n2, n3, n4}, and n1, n2, n3, and n4 are positive integers.

第一设备为覆盖增强等级2，或者为覆盖增强等级3，或者为覆盖增强模式B的终端设备，根据下行控制信息确定的第一资源块数量为{4,6}中的元素。例如，第一重复次数为数据信道的重复次数。第一重复次数可以为{n1,n2,n3,n4,n5,n6,n7,n8}中的元素，其中n1，n2，n3，n4，n5，n6，n7，n8为正整数The first device is coverage enhancement level 2, or coverage enhancement level 3, or coverage enhancement mode B terminal device, and the number of first resource blocks determined according to downlink control information is elements in {4, 6}. For example, the first number of repetitions is the number of repetitions of the data channel. The first number of repetitions can be elements in {n1, n2, n3, n4, n5, n6, n7, n8}, where n1, n2, n3, n4, n5, n6, n7, n8 are positive integers

第一设备为覆盖增强等级2，或者为覆盖增强等级3，或者为覆盖增强模式B的终端设备或者为覆盖增强等级0，或者为覆盖增强等级1，或者为覆盖增强模式A的终端设备，并且第一重复次数为下行控制信息的重复次数，则第一重复次数为{r1,r2,r3,r4}中的元素，其中r1>r2>r3>r4，r1，r2，r3，r4为正整数。The first device is coverage enhancement level 2, or coverage enhancement level 3, or coverage enhancement mode B terminal device, or coverage enhancement level 0, or coverage enhancement level 1, or coverage enhancement mode A terminal device, and The first repetition count is the repetition count of the downlink control information, and the first repetition count is the element in {r1, r2, r3, r4}, where r1>r2>r3>r4, r1, r2, r3, r4 are positive integers .

下面举例描述多个资源块数量集合与多个重复次数集合之间的关系。The following examples describe the relationship between multiple resource block quantity sets and multiple repetition times sets.

第一个例子，第二资源块数量集合为{a}，第三资源块数量集合为{b,c},{a}关联的重复次数集合包括2个元素，{b,c}关联的重复次数集合包括4个元素，例如，如表1所示，其中，a小于b，并且a小于c，a,b和c都是正整数。In the first example, the second resource block quantity set is {a}, and the third resource block quantity set is {b,c}. The set of associated repetition times for {a} includes 2 elements, {b,c} is associated repetition The order set includes 4 elements, for example, as shown in Table 1, where a is less than b, and a is less than c, and a, b, and c are all positive integers.

例如，a为2，b为4，c为6，以表2为例描述。即资源块数量4和6组成的第三资源块数量集合{4,6}对应第三重复次数集合，第三重复次数集合包括4个元素，例如可以为{1,4,16,32}。资源块数量为4时，假设第一窄带内的6个RB的编号分别为0,1,2,3,4,5。则资源块的起始位置可以为0或2，若起始位置为0，则为0,1,2,3这四个RB，若起始位置为2，则为2,3,4,5这四个RB。资源块数量为6时，则资源块的起始位置只能是0，为整个窄带上的RB。资源块数量2组成的第二资源块数量集合{2}对应第二重复次数集合，第二重复次数集合包括2个元素，例如可以为{16,32}。资源块数量为2时，则资源块的起始位置可以为{2，4}或者{0，4}或者{1，4}或者{0，2}中的值，假设起始位置为2，则为2,3这两个RB；假设起始位置为4，则为4,5这两个RB；假设起始位置为1，则为1,2这两个RB，假设起始位置为0，则为0,1这两个RB。For example, if a is 2, b is 4, and c is 6, take Table 2 as an example. That is, the third resource block number set {4, 6} composed of resource block numbers 4 and 6 corresponds to the third repetition number set, and the third repetition number set includes 4 elements, for example, {1, 4, 16, 32}. When the number of resource blocks is 4, it is assumed that the numbers of the 6 RBs in the first narrowband are 0, 1, 2, 3, 4, and 5, respectively. Then the starting position of the resource block can be 0 or 2. If the starting position is 0, it is the four RBs of 0, 1, 2, 3, and if the starting position is 2, it is 2, 3, 4, 5 These four RBs. When the number of resource blocks is 6, the starting position of the resource block can only be 0, which is the RB on the entire narrowband. The second resource block quantity set {2} composed of the resource block quantity 2 corresponds to the second set of repetition times, and the second set of repetition times includes 2 elements, which may be {16, 32}, for example. When the number of resource blocks is 2, the starting position of the resource block can be {2, 4} or {0, 4} or {1, 4} or {0, 2}, assuming the starting position is 2, It is the two RBs of 2, 3; assuming the starting position is 4, it is the two RBs of 4 and 5; assuming the starting position is 1, then it is the two RBs of 1, and assuming the starting position is 0 , It is the two RBs of 0 and 1.

可选地，资源块数量为2时，对应第二重复次数集合，第二重复次数集合包括2个元素，2个元素可以是{n2,n4}或{n1,n3}或{n1,n2}，n1<n2<n3<n4，n1,n2,n3,n4为正整数。资源块数量4时，第二重复次数集合包括的四个元素可以为{n1,n2,n3,n4}。资源块数量为6时，第二重复次数集合包括的四个元素可以为{n1,n2,n3,n4}。Optionally, when the number of resource blocks is 2, it corresponds to the second set of repetition times. The second set of repetition times includes 2 elements, and the 2 elements can be {n2,n4} or {n1,n3} or {n1,n2} , N1<n2<n3<n4, n1, n2, n3, n4 are positive integers. When the number of resource blocks is 4, the four elements included in the second set of repetition times may be {n1, n2, n3, n4}. When the number of resource blocks is 6, the four elements included in the second set of repetition times may be {n1, n2, n3, n4}.

资源块数量为4时，资源块的起始位置可以设计为0或2，资源块数量为2时，资源块的起始位置可以设计为4或0，资源块数量为6时，资源块的起始位置只能设计为0。资源块的起始位置的设计需要考虑一些因素，在设计的过程中，若RB是4，则可以将资源块的起始位置设计为0，这样可以将0,1,2,3这四个RB分配给一个设备，若RB是2，则可以将资源块的起始位置设置为4，这样可以将4,5这两个RB分配给另外一个设备，这样，两个设备可以在一个窄带内传输，可以提高资源的利用率。在设计的过程中，若RB数是4时，则可以将资源块的起始位置设计为2，这样可以将2,3,4,5这四个RB分配给一个设备，若RB是2，则可以将资源块的起始位置设置为0，这样可以将0,1这两个RB分配给另外一个设备，这样，两个设备可以在一个窄带内传输，可以提高资源的利用率。When the number of resource blocks is 4, the starting position of the resource block can be designed to be 0 or 2, when the number of resource blocks is 2, the starting position of the resource block can be designed to be 4 or 0, and when the number of resource blocks is 6, the starting position of the resource block The starting position can only be designed as 0. The design of the starting position of the resource block needs to consider some factors. In the design process, if RB is 4, the starting position of the resource block can be designed as 0, so that the four of 0, 1, 2, 3 The RB is allocated to one device. If the RB is 2, the starting position of the resource block can be set to 4, so that the two RBs 4 and 5 can be allocated to another device, so that the two devices can be in a narrowband Transmission can improve resource utilization. In the design process, if the number of RBs is 4, the starting position of the resource block can be designed as 2, so that the four RBs 2, 3, 4, and 5 can be allocated to one device. If the RB is 2, The start position of the resource block can be set to 0, so that the two RBs 0 and 1 can be allocated to another device. In this way, the two devices can transmit in a narrow band, which can improve resource utilization.

因此，在表2中，当RB数是4时，资源块的起始位置可以设计为0或2，重复次数集合可以包括4个元素，这样有8种组合；当RB数是6时，资源块的起始位置只能是0，重复次数集合可以包括4个元素，这样有4种组合；当RB数是2时，资源块的起始位置可以为0或4，重复次数集合可以包括2个元素，这样有4种组合总共有8+4+4＝16种组合，需要4比特就可以指示。当然，表2只是举例说明，在当RB数是2时，资源块的起始位置还可以是{2,4}中的一个元素，或者资源块的起始位置可以是{1,4}中的一个元素，或者资源块的起始位置可以是{0,2}中的一个元素Therefore, in Table 2, when the number of RBs is 4, the starting position of the resource block can be designed to be 0 or 2, and the set of repetition times can include 4 elements, so there are 8 combinations; when the number of RBs is 6, the resource block The starting position of the block can only be 0, the set of repetitions can include 4 elements, so there are 4 combinations; when the number of RBs is 2, the starting position of the resource block can be 0 or 4, and the set of repetitions can include 2. In this way, there are 4 combinations and a total of 8+4+4=16 combinations, which can be indicated by 4 bits. Of course, Table 2 is just an example. When the number of RBs is 2, the starting position of the resource block can also be an element in {2,4}, or the starting position of the resource block can be in {1,4} An element of, or the starting position of the resource block can be an element in {0,2}

需要说明的是，在表2中，RB是4或6时对应的是同一个重复次数集合，在实际应用中，不同的RB数也可以对应不同的重复次数，即不同的资源块数量集合对应不同的重复次数集合，同一资源块数量集合中的不同的元素可以对应同一重复次数集合或者不同重复次数集合，本申请实施例对此不作限制。It should be noted that in Table 2, when RB is 4 or 6, it corresponds to the same set of repetition times. In practical applications, different RB numbers can also correspond to different repetition times, that is, different resource block quantity sets correspond to Different sets of repetition times, different elements in the same resource block quantity set may correspond to the same set of repetition times or different sets of repetition times, which is not limited in the embodiment of the present application.

That is, the third resource block number set {4, 6} composed of resource block numbers 4 and 6 corresponds to the third repetition number set, and the third repetition number set includes 4 elements, for example, {1, 4, 16, 32}. Assume that the numbers of the 6 RBs in the first narrowband are 0, 1, 2, 3, 4, and 5 respectively. When the number of resource blocks is 4, the starting position of the resource block can be 0, 1, 2, and if the starting position is 0, it will be the four RBs of 0, 1, 2 and 3. If the starting position is 1, It is the four RBs of 1, 2, 3, and 4. If the starting position is 2, it is the four RBs of 2, 3, 4, and 5.

That is, the third resource block number set {4, 6} composed of resource block numbers 4 and 6 corresponds to the third repetition number set, and the third repetition number set includes 4 elements, for example, {1, 4, 16, 32}. When the number of resource blocks is 4, it is assumed that the numbers of the 6 RBs in the first narrowband are 0, 1, 2, 3, 4, and 5, respectively. Then the starting position of the resource block can be 0, and if the starting position is 0, it is the four RBs of 0, 1, 2, and 3. When the number of resource blocks is 6, the starting position of the resource block can only be 0, which is the RB on the entire narrowband. The second resource block number set {1, 2} composed of resource block numbers 2 and 1 corresponds to the second set of repetition times, and the second set of repetition times includes 2 elements, which may be {16, 32}, for example. When the number of resource blocks is 2, the starting position of the resource block can be {2, 4} or {0, 4} or {1, 4} or {0, 2}, assuming that the starting position is 2.

Assuming the starting position is 0, it is the two RBs of 0 and 1; assuming the starting position is 4, it is 4,5. Two RBs.

资源块的起始位置的设计需要考虑一些因素，例如，假设RB数是4时，尽可能使得资源块的起始位置从0开始，这样可以将0,1,2,3这四个RB分配给一个设备，RB是2时，尽可能使得资源块的起始位置为4，这样可以将4,5这两个RB分配给另外一个设备，这样，两个设备可以在一个窄带内传输，可以提高资源的利用率。The design of the starting position of the resource block needs to consider some factors. For example, if the number of RBs is 4, try to make the starting position of the resource block start from 0 as much as possible, so that the four RBs of 0, 1, 2 and 3 can be allocated For a device, when the RB is 2, try to make the starting position of the resource block 4 as much as possible, so that the two RBs 4 and 5 can be allocated to another device, so that the two devices can transmit in a narrow band. Improve resource utilization.

因此，在表8中，当RB数是4时，资源块的起始位置可以设计为0，重复次数集合可以包括4个元素，这样有4种组合；当RB数是6时，资源块的起始位置只能是0，重复次数集合可以包括4个元素，这样有4种组合；当RB数是2时，资源块的起始位置可以设计为{2,4}{0,4}{1,4}{0,2}中的一种，重复次数集合可以包括2个元素，这样有4种组合；当RB数是1时，资源块的起始位置为0或4，重复次数集合可以包括2个元素，这样有4种组合，总共有4+4+4+4＝16种组合，需要4比特就可以指示。资源块数量为4时，资源块的起始位置可以设计为0，资源块数量为1时，资源块的起始位置可以设计为4，资源块数量为6时，资源块的起始位置只能设计为0。资源块的起始位置的设计需要考虑一些因素，在设计的过程中，若RB是4，则可以将资源块的起始位置设计为0，这样可以将0,1,2,3这四个RB分配给一个设备，若RB是1，则可以将资源块的起始位置设置为4，这样可以将4RB分配给另外一个设备，这样，两个设备可以在一个窄带内传输，可以提高资源的利用率。在设计的过程中，若RB数是4时，则可以将资源块的起始位置设计为2，这样可以将2,3,4,5这四个RB分配给一个设备，若RB是1，则可以将资源块的起始位置设置为0，这样可以将0这个RB分配给另外一个设备，这样，两个设备可以在一个窄带内传输，可以提高资源的利用率。Therefore, in Table 8, when the number of RBs is 4, the starting position of the resource block can be designed to be 0, and the set of repetition times can include 4 elements, so there are 4 combinations; when the number of RBs is 6, the resource block The starting position can only be 0, and the set of repetition times can include 4 elements, so there are 4 combinations; when the number of RBs is 2, the starting position of the resource block can be designed as {2,4}{0,4}{ One of 1,4}{0,2}, the set of repetition times can include 2 elements, so there are 4 combinations; when the number of RBs is 1, the starting position of the resource block is 0 or 4, and the set of repetition times It can include 2 elements, so there are 4 combinations, a total of 4+4+4+4=16 combinations, and 4 bits are needed to indicate. When the number of resource blocks is 4, the starting position of the resource block can be designed to be 0, when the number of resource blocks is 1, the starting position of the resource block can be designed to be 4, and when the number of resource blocks is 6, the starting position of the resource block is only Can be designed as 0. The design of the starting position of the resource block needs to consider some factors. In the design process, if RB is 4, the starting position of the resource block can be designed as 0, so that the four of 0, 1, 2, 3 RB is allocated to one device. If RB is 1, the starting position of the resource block can be set to 4, so that 4RB can be allocated to another device. In this way, two devices can transmit in a narrow band, which can improve resource efficiency. Utilization rate. In the design process, if the number of RBs is 4, the starting position of the resource block can be designed as 2, so that the four RBs 2, 3, 4, and 5 can be allocated to one device. If the RB is 1, Then the starting position of the resource block can be set to 0, so that the RB of 0 can be allocated to another device. In this way, the two devices can transmit in a narrow band, which can improve resource utilization.

In this way, there are 4 combinations and a total of 12+4=16 combinations, which can be indicated by 4 bits.

表11和表12中的第二重复次数集合和第三重复次数集合包括的元素个数相同，但是第二重复次数集合和第三重复次数集合至少存在一个元素不同，即两个重复次数集合属于不同的重复次数集合。The second set of repetitions and the third set of repetitions in Tables 11 and 12 include the same number of elements, but there is at least one element difference between the second set of repetitions and the third set of repetitions, that is, the two sets of repetitions belong to A collection of different repetition times.

Optionally, the number of repetitions corresponding to a and b is less than or equal to 8.

例如，a为4，b为6以表13为例描述。即资源块数量4对应的第二重复次数集合包括4个元素，例如可以为{1,4,16,32}。资源块数量6也对应第二重复次数集合例如可以为{1,4,16,32}。假设第一窄带内的6个RB的编号分别为0,1,2,3,4,5。资源块数量为4时，则资源块的起始位置可以为0或1或2，若起始位置为0，则为0,1,2,3这四个RB，若起始位置为1，则为1,2,3,4这四个RB。若起始位置为2，则为2,3,4,5这四个RB。资源块数量为6时，则资源块的起始位置只能是0，为整个窄带上的RB。For example, if a is 4 and b is 6, take Table 13 as an example. That is, the second set of repetition times corresponding to the number of resource blocks of 4 includes 4 elements, which may be {1, 4, 16, 32}, for example. The number of resource blocks 6 also corresponds to the second set of repetition times, for example, {1, 4, 16, 32}. Assume that the numbers of the 6 RBs in the first narrowband are 0, 1, 2, 3, 4, and 5 respectively. When the number of resource blocks is 4, the starting position of the resource block can be 0 or 1 or 2. If the starting position is 0, it is the four RBs of 0, 1, 2 and 3. If the starting position is 1, The four RBs are 1, 2, 3, and 4. If the starting position is 2, it is the four RBs 2, 3, 4, and 5.

In this way, there are 4 combinations and a total of 12+4=16 combinations, which can be indicated by 4 bits. For example, the control information includes a third field, and the third field includes 4 bits. The 4 bits of the third field can indicate that the number of the first resource block, the starting position of the resource block, and the first number of repetitions are among the 16 combinations What kind of combination.

For example, when the number of resource blocks is 4 or 6, the four elements included in the second set of repetition times may be {n1, n2, n3, n4} n1, n2, n3, n4 are positive integers.

可选地，控制信息包括第一字段和第二字段，第一字段包括2个比特，第一字段用于指示第一资源块数量和资源块起始位置，第二字段包括2个比特，第二字段用于指示第一重复次数。以表13为例，第一字段为2比特，第一字段用于指示资源块数量4对应的3种可能的资源块起始位置，资源块数量6对应的1种资源块起始位置，则资源块数量和资源块起始位置有4种组合，即2比特就可以指示资源分配为这4种组合中的哪种组合。第二字段为2比特，第二重复次数集合包括4个元素，则需要2比特就可以指示第一重复次数为这四个元素中的哪个元素。Optionally, the control information includes a first field and a second field. The first field includes 2 bits. The first field is used to indicate the number of the first resource block and the start position of the resource block. The second field includes 2 bits. The second field is used to indicate the first number of repetitions. Taking Table 13 as an example, the first field is 2 bits, and the first field is used to indicate the start position of 3 possible resource blocks corresponding to the number of resource blocks of 4, and the start position of 1 resource block corresponding to the number of resource blocks of 6, then There are 4 combinations of the number of resource blocks and the starting position of the resource blocks, that is, 2 bits can indicate which of these 4 combinations the resource is allocated. The second field is 2 bits, and the second set of repetition times includes 4 elements, and 2 bits are needed to indicate which element of the four elements the first repetition number is.
