如果一个服务小区上UE(User Equipment，用户设备)配置了高层参数CrossCarrierSchedulingConfig，则DCI中的载波指示字段(carrier indicator field)取值即为CrossCarrierSchedulingConfig。一个服务小区上UE需要监听UE专用搜索空间的PDCCH候选，若UE没有配置载波指示字段，则UE监听的PDCCH候选中不包含载波指示字段；若UE配置了载波指示字段，则UE监听的PDCCH候选中包含载波指示字段。若UE配置在另一个服务小区上监听有对应某辅小区载波指示字段的PDCCH候选，则UE不期望在辅小区中监听PDCCH候选。对于UE监听PDCCH候选的服务小区，UE至少监听本服务小区的PDCCH候选。
鉴于一个DCI只能包含一个小区的调度信息，所以，现有技术中为了调度多个小区，需要发送多个DCI。每一个DCI均需要占用一个对应的PDCCH(物理下行共享信道)。因此，为了调度多个小区，需要占用多个PDCCH，消耗了较多的通信资源。另外，一个DCI仅包含一个对应小区的调度信 息，受到该DCI中各个字段的长度的限制，其难以兼容多个小区的调度信息。

具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
实施例1
本实施例提供一种DCI的生成方法。参照图1，该DCI的生成方法包括以下步骤：
步骤S101、根据与对象小区对应的期望DCI的各个字段的长度得到目标DCI的各个字段的长度。对象小区的数量为多个，期望DCI为用于单独调度每一个对象小区所需的DCI，目标DCI的各个字段的长度为兼容期望DCI的对应字段所需的长度。
步骤S102、根据预设对应关系对目标DCI的各个字段分别构建子字段以使目标DCI的每一个字段的各个子字段分别与一个对象小区相对应。

设对象小区的数量为K。根据现有技术，为了分别对K个对象小区进行单独调度时所需要分别设置的期望DCI，以频域资源分配字段为例，这些期望DCI的频域资源分配字段分别具有与对应的对象小区对应的长度。在一种可选的实施方式中，以这些长度中的最大值作为目标DCI的频域资源分配字段的长度。目标DCI的其他的字段的长度的确定方式与此类似。据此，即可使得生成的目标DCI的长度能兼容多个对象小区的调度信息，从而实现一个目标DCI包含多个对象小区的调度信息以支持同时对多个对象小区进行调度。在另一种可选的实施方式中，目标DCI的频域资源分配字段的长度为这些长度中的最大值与一预设位宽值的和，该预设位宽值对应的子字段，用于对多个对象小区的资源分配类型进行配置。目标DCI的其他的字段的长度的确定方式与此类似。
作为一种可选的实施方式，设目标DCI的某一字段的长度为W位，则该字段包含一个W位的调度信息，该W位的调度信息用于对多个对象小区进行调度。具体实施时，目标DCI通过一个预设的PDCCH发送，该PDCCH对应多个对象小区。多个对象小区收到该目标DCI之后，对该目标DCI进行解析，分别在该目标DCI的该字段得到该W位的调度信息。多个对象小区中，如果某一对象小区对应的期望DCI的该字段具有Y(Y小于等于W)位，则该对象小区以该W位的调度信息中的最低的Y位作为该对象小区对应的子字段作为该对象小区的调度信息。例如，该字段需要W位的对象小 区，以该完整字段作为与该对象小区对应的子字段以获得对应的调度信息；该字段需要X(X小于W)位的对象小区，则以该字段中的最低的X位作为与该对象小区对应的子字段以获得对应的调度信息。目标DCI中的其他字段对多个对象小区的作用方式类似。基于此，一个目标DCI即可兼容多个小区的配置信息。
在第一种可选的实施方式中，如果多个对象小区均只支持资源分配类型1，则频域资源分配字段的长度(位数)取决于多个对象小区对应的PRB个数最大的对象小区的BWP(部分带宽)。即，如果多个对象小区均只支持资源分配类型1，则目标DCI的频域资源分配字段的长度为
Figure PCTCN2021075600-appb-000019
其中n∈[1,K]，K为对象小区的数量。
Figure PCTCN2021075600-appb-000020
Figure PCTCN2021075600-appb-000021
分别与每一个对象小区相对应。
在第二种可选的实施方式中，如果多个对象小区均只支持资源分配类型0，则频域资源分配字段的长度取决于多个对象小区对应的N RBG个数最大的对象小区的BWP。即，如果多个对象小区均只支持资源分配类型0，则目标DCI的频域资源分配字段的长度为max(N(n) RBG)，其中，n∈[1,K]，K为对象小区的数量。
Figure PCTCN2021075600-appb-000022
分别与每一个对象小区相对应。
在第三种可选的实施方式中，如果多个对象小区中，一部分对象小区只支持资源分配类型0，另一部分对象小区只支持资源分配类型1，则频域资源分配字段的长度为：
Figure PCTCN2021075600-appb-000023
其中，
Figure PCTCN2021075600-appb-000024
分别与只支持资源分配类型1的一部分对象小区中的每一个对象小区相对应，N(j) RBG分别与只支持资源分配类型0的一部分对象小区中的每一个对象小区相对应。作为一种可选的实施方式，多个对象小区中，只支持资源分配类型0的一部分对象小区的数量为L，只支持资源分配类型1的另一部分对象小区的数量为M(L+M＝K，K为期望调度的对象小区的数量，L、M、K均为正整数)，则i∈[1,L],j∈[1,M]。
在第四种可选的实施方式中，如果多个对象小区均既支持资源分配类型0又支持资源分配类型1，则目标DCI的频域资源分配字段包括一位类型指示位，类型指示位用于指示对象小区均为资源分配类型1或均为资源分配类型0，则频域资源分配字段的长度为
Figure PCTCN2021075600-appb-000025
其中，
Figure PCTCN2021075600-appb-000026
与对象小区均被指示为资源分配类型1的模式相对应；N(n) RBG与对象小区均被指示为资源分配类型0的模式相对应，K为对象小区的数量。作为一种可选的实施方式，DCI的频域资源分配字段的最高位(MSB)作为类型指示位。当类型指示位的值为0时，各个对象小区均被指示为资源分配类型0；当类型指示位的值为1时，各个对象小区均被指示为资源分配类型1。
在第五种可选的实施方式中，目标DCI的频域资源分配字段包括K位类型指示位，每一位类型指示位分别对应一个对象小区以指示对象小区资源分配类型1或资源分配类型0，则频域资源分配字段的长度为
Figure PCTCN2021075600-appb-000027
Figure PCTCN2021075600-appb-000028
其中，
Figure PCTCN2021075600-appb-000029
与对象小区均被指示为资源分配类型1的模式相对应；N(n) RBG与对象小区均被指示为资源分配类型0的模式相对应，K为对象小区的数量。在作为一种可选的实施方式，DCI的频域资源分配字段的最高的K位均为类型指示位。其中，频域资源分配字段的最高位与第一个对象 小区相对应，当该位的值为0时，第一个对象小区被指示为资源分配类型0；当该位的值为1时，第一个对象小区被指示为资源分配类型1；如果第一个对象小区仅支持资源分配类型0或者第一个对象小区仅支持资源分配类型1，则第一个对象小区忽略该位，其资源分配类型不受该位的影响。频域资源分配字段的第二高位与第二个对象小区相对应，当该位的值为0时，第二个对象小区被指示为资源分配类型0；当该位的值为1时，第二个对象小区被指示为资源分配类型1；如果第二个对象小区仅支持资源分配类型0或者第二个对象小区仅支持资源分配类型1，则第二个对象小区忽略该位，其资源分配类型不受该位的影响。依此类推，频域资源分配字段的第K高位与第K个对象小区相对应，当该位的值为0时，第K个对象小区被指示为资源分配类型0；当该位的值为1时，第K个对象小区被指示为资源分配类型1；如果第K个对象小区仅支持资源分配类型0或者第K个对象小区仅支持资源分配类型1，则第K个对象小区忽略该位，其资源分配类型不受该位的影响。
根据期望DCI的对应字段的长度的最大值得到目标DCI的对应字段的长度，使得目标DCI的对应字段通过较短的长度即可兼容需要调度的所有多个对象小区，节省了资源。
本实施例的DCI的生成方法通过对目标DCI的长度及相应字段所包含的信息的合理设置，使得一个目标DCI兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅占用一个PDCCH，节省了PDCCH等通信资源。
实施例3
在实施例1的基础上，本实施例提供一种DCI的生成方法。在本实施例中，作为一种具体的实施方式，在步骤S101中，根据多个期望DCI的对应字段的长度的和得到目标DCI的对应字段的长度。
设对象小区的数量为K。根据现有技术，为了分别对K个对象小区进行单独调度时所需要分别设置的期望DCI，以频域资源分配字段为例，这些期望DCI的频域资源分配字段分别具有与对应的对象小区对应的长度。设第i个对象小区的期望DCI的频域资源分配字段的长度为W i(i∈[1,K])。
在一种可选的实施方式中，目标DCI的频域资源分配字段的长度
Figure PCTCN2021075600-appb-000030
频域资源分配字段中，最低的W 1位(即频域资源分配字段第W 1位至第1位，第1位为频域资源分配字段的最低位)构成第一子字段，第一子字段与第一对象小区相对应；与第一子字段相邻的W 2位(即频域资源分配字段第(W 1+W 2)位至第(W 1+1)位)构成第二子字段，第二子字段与第二对象小区相对应。依此类推，频域资源分配字段的最高W K位构成第K子字段，第K子字段与第K对象小区相对应。多个对象小区接收到该目标DCI之后，从目标DCI中解析出频域资源分配字段，并根据预设对应关系从频域资源分配字段中的对应子字段获得对应的配置信息。目标DCI的其他的字段的长度的确定方式和作用方式与此类似。据此，即可使得生成的目标DCI的长度能兼容多个对象小区的调度信息，从而实现一个目标DCI包含多个对象小区的调度信息以支持同时对多个对象小区进行调度。
在另一种可选的实施方式中，目标DCI的频域资源分配字段的长度

频域资源分配字段中，最低的W 1位(即频域资源分配字段第W 1位至第1位，第1位为频域资源分配字段的最低位)构成第一子字段，第一子字段与第一对象小区相对应；与第一子字段相邻的W 2位(即频域资源分配字段第(W 1+W 2)位至第(W 1+1)位)构成第二子字段，第二子字段与第二对象小区相对 应。依此类推，频域资源分配字段的第

位至第
Figure PCTCN2021075600-appb-000033
位构成第K子字段，第K子字段与第K对象小区相对应。频域资源分配字段的最高的A位用于对多个对象小区的资源分配类型进行配置。目标DCI的其他的字段的长度的确定方式和作用方式与此类似。
根据多个期望DCI的对应字段的长度的和得到目标DCI的对应字段的长度，可以使与每一个对象小区对应的子字段相对独立，所以，对某一个对象小区的配置不会受到其他小区的配置的影响或限制，具有较高的灵活性。
本实施例的DCI的生成方法通过对目标DCI的长度及相应字段所包含的信息的合理设置，使得一个目标DCI兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅占用一个PDCCH，节省了PDCCH等通信资源。
实施例4
在实施例1的基础上，本实施例提供一种DCI的生成方法。参照图2，该DCI的生成方法还包括以下步骤：
步骤S100、将其中一个对象小区设置为参考小区。
步骤S101包括：根据参考小区的期望DCI的各个字段的长度得到目标DCI的各个字段的长度。
步骤S102包括：将目标DCI的每一个字段同时与多个对象小区相对应。
步骤S103包括：将与参考小区对应的期望DCI作为目标DCI。
也即，在对多个对象小区进行调度时，参考小区以外的其他各个对象小区均采用与参考小区相同的配置。
具体实施时，目标DCI(即与参考小区对应的期望DCI)通过一个预设的PDCCH发送，该PDCCH对应多个对象小区。多个对象小区收到该目标DCI之后，对该目标DCI进行解析，即可得到对应的配置信息。根据本实施例的DCI的生成方法，一个DCI能够兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅占用一个PDCCH，节省了PDCCH等通信资源。
实施例5
本实施例提供一种小区的调度方法。参照图3，该小区的调度方法包括：利用实施例1-3中任意一个实施例的DCI的生成方法生成目标DCI；
该小区的调度方法还包括以下步骤：
步骤S104、根据目标DCI调度多个对象小区。
目标DCI能够兼容多个对象小区的调度信息，所以，通过一个目标DCI即可支持同时对多个目标小区的调度。根据目标DCI调度多个对象小区，仅占用一个PDCCH，节省了PDCCH等通信资源。
实施例6
在实施例5的基础上，本实施例提供一种小区的调度方法。参照图4，该小区的调度方法还包括以下步骤：
步骤S11、构建部分带宽配置表格。部分带宽配置表格包括与每一个对象小区对应的部分带宽配 置信息。
则步骤S104包括步骤S1041、根据目标DCI的部分带宽指示字段查询部分带宽配置表格以获得与每一个对象小区对应的部分带宽配置信息，根据部分带宽配置信息配置对应的对象小区。
在第一种可选的实施方式中，部分带宽配置表格由高层信令(RRC)信令配置。以对象小区的数量为2的情形为例，参照表1，部分带宽配置表格的第一列为索引列，第二列为第一小区cell1对应的部分带宽配置信息，第三列为第二小区cell2对应的部分带宽配置信息。当DCI的部分带宽指示字段的值为1时，对应部分带宽配置表格中部分带宽配置索引的值为1的行，因此，第一小区cell1对应的部分带宽配置信息为1，第二小区cell2对应的部分带宽配置信息为1。第一小区cell1和第二小区cell2根据部分带宽配置信息进行BWP切换。部分带宽配置信息的具体含义是本领域技术人员清楚的，此处不再赘述。
在其他可选的实施方式中，部分带宽配置表格支持大于等于3个对象小区，部分带宽配置表格的列数与对象小区的数量相适应。
在另一种可选的实施方式中，采用的部分带宽配置表格的行列的形式是根据表1转置得到的。
表1
部分带宽配置索引 cell1部分带宽配置信息 cell2部分带宽配置信息
0 0 0
1 1 1
2 2 2
在第二种可选的实施方式中，为了提高BWP切换的效率，部分带宽配置信息包括激活模式，激活模式用于指示对象小区保持当前的BWP。参照表2，该激活模式值采用“active BWP”表征，表示不进行BWP切换，仍然使用当前的BWP。其益处在于，可以采用单小区PDCCH进行单个小区的BWP切换，而多小区PDCCH的部分或全部BWP均是针对当前BWP进行调度，不需要进一步调整激活BWP，有助于提高BWP切换的效率。根据表2，当DCI的部分带宽指示字段的值为1时，对应部分带宽配置表格中部分带宽配置索引的值为1的行，因此，第一小区cell1对应的部分带宽配置信息为“active BWP”，第一小区cell1仍然使用当前的BWP；第二小区cell2对应的部分带宽配置信息为1，第二小区cell2根据部分带宽配置信息进行BWP切换。
在其他可选的实施方式中，部分带宽配置表格支持大于等于3个对象小区，部分带宽配置表格的列数与对象小区的数量相适应。
在另一种可选的实施方式中，采用的部分带宽配置表格的行列的形式是根据表2转置得到的。
表2
部分带宽配置索引 cell1部分带宽配置信息 cell2部分带宽配置信息
0 0 0
1 active BWP 1
2 2 active BWP

通过部分带宽配置表格的设置，本实施例的小区的调度方法在对多个小区进行调度时，可以同时对多个小区的部分带宽进行配置，提高了效率。
实施例7
在实施例5的基础上，本实施例提供一种小区的调度方法。参照图5，在一种可选的实施方式中，该小区的调度方法还包括以下步骤：
步骤S12、构建时域资源分配表格。时域资源分配表格包括分别与每一个对象小区对应的时域资源配置信息。
则步骤S104包括步骤S1042、根据目标DCI的时域资源分配字段查询时域资源分配表格以获得与每一个对象小区对应的时域资源配置信息，根据时域资源配置信息配置对应的对象小区。
在第一种可选的实施方式中，时域资源分配表格包括索引区和多个表格区块；每一个表格区块分别与一个对象小区相对应；索引区的每一个元素分别用于同时索引多个表格区块的对应元素以获取时域资源配置信息。在步骤S1032中，根据索引区的与时域资源分配字段对应的元素同时索引多个表格区块的对应元素以获取时域资源配置信息。
具体参照表3，时域资源分配表格为单一表格。时域资源分配表格中“TDRA index(时域资源分配索引)”列作为索引区。该时域资源分配表格的第2-5列构成第一表格区块，与第一小区cell1相对应。其中，第2列“K0(DL)or K2(UL)(时域偏置)for cell 1”列包括时域偏置信息，“SLIV for cell 1”列包括SLIV配置信息，“Mapping type for cell 1”列包括映射类型配置信息，“Repetition for cell 1”列包括重传配置信息。该时域资源分配表格的第6-9列构成第二表格区块，与第二小区cell2相对应。第二表格区块的结构与第一表格区块类似。
“TDRA index”列的每一行对应的数值分别为0至15的16个整数。TDRA index的值以及对应的时域偏置/SLIV/mapping type/repetition的数值与现有技术中相似，所以，表3省略了个别行为示出。
目标DCI生成后，根据目标DCI的时域资源分配字段对应的数值(对应TDRA index的值)在时域资源分配表格中查询得到每一个小区的时域资源配置信息。例如，目标DCI的时域资源分配字段的数值为1，则根据时域资源分配表格中TDRA index的值为1的行得到各个小区的时域资源配置信息。
在其他可选的实施方式中，时域资源分配表格支持大于等于3个对象小区，时域资源分配表格包含的表格区块的数量与对象小区的数量相适应。
在另一种可选的实施方式中，采用的时域资源分配表格的行列的形式是根据表3转置得到的。
表3

Figure PCTCN2021075600-appb-000035
在第二种可选的实施方式中，时域资源分配表格包括多个子表格；每一个子表格均包括一个索引区和一个表格区块，每一个表格区块分别与一个对象小区相对应，索引区的每一个元素分别用于索引对应的表格区块的对应元素以获取时域资源配置信息。则在步骤1032中，根据索引区的与时域资源分配字段对应的元素索引表格区块的对应元素以分别获取与每一个对象小区对应的时域资源配置信息。
当对象小区的数量为2时，时域资源分配表格包括2个子表格。2个子表格分别参照表4、表5。第一子表格(表4)与第一小区cell1相对应，第二子表格(表5)与第二小区cell2相对应。
第一子表格中，“TDRA index”列作为索引区，第2-4列构成第一表格区块，与第一小区cell1相对应。其中，第2列“K0(DL)or K2(UL)(时域偏置)”列包括时域偏置信息，“SLIV”列包括SLIV配置信息，“Mapping type”列包括映射类型配置信息，“Repetition for cell 1”列包括重传配置信息。第一表格区块包括时域偏置/SLIV/mapping type/repetition等4列，分别用于配置第一小区cell1的时域偏置/SLIV/mapping type/repetition信息。第二子表格的结构与第一子表格类似，“TDRA index”列作为索引区，第2-4列构成第二表格区块，与第二小区cell1相对应。
目标DCI生成后，根据目标DCI的时域资源分配字段的数值(对应TDRA index的值)分别在每一个子表格中查询得到该小区的时域资源配置信息。例如，目标DCI的时域资源分配字段的数值为1，则根据第一子表格中TDRA index的值为1的行得到第一小区cell1的时域资源配置信息，根据第二子表格中TDRA index的值为1的行得到第二小区cell2的时域资源配置信息。
在其他可选的实施方式中，时域资源分配表格支持大于等于3个对象小区，时域资源分配表格包含的子表格的数量与对象小区的数量相适应。
在另一种可选的实施方式中，时域资源分配表格的子表格的行列的形式是根据表4、表5转置得到的。

“TDRA index”列的每一行对应的数值分别为0至15的16个整数。TDRA index的值以及对应的时域偏置/SLIV/mapping type的数值与现有技术中相似，所以，表4、表5均省略了个别行为示出。
在另一种可选的实施方式中，将本实施例的小区的调度方法与实施例6的小区的调度方法相结合，得到如图6所示的小区的调度方法。在步骤S13中，构建时域资源分配表格和部分带宽配置表格。在步骤S1043中，根据目标DCI的时域资源分配字段查询时域资源分配表格以获得与每一个对象小区对应的时域资源配置信息，根据目标DCI的部分带宽指示字段查询部分带宽配置表格以获得与每一个对象小区对应的部分带宽配置信息，根据部分带宽配置信息和时域资源配置信息配置对应的对象小区。
本实施例的小区的调度方法通过对时域资源分配表格的改进，可以通过一个DCI实现同时对多个小区的调度，节省了PDCCH等通信资源。
实施例8
本实施例提供一种小区的调度方法。参照图7，在一种可选的实施方式中，该小区的调度方法包括：利用实施例4的DCI的生成方法生成目标DCI；
该小区的调度方法还包括以下步骤：
步骤S104、根据目标DCI调度多个对象小区。
在另一种可选的实施方式中，参照图8，该小区的调度方法还包括步骤S15、构建参考时域资源分配表格。参考时域资源分配表格包括与参考小区相对应的时域资源配置信息。则步骤S104包括步骤S1045：根据目标DCI的时域资源分配字段查询参考时域资源分配表格以获得时域资源配置信息，根据时域资源配置信息配置每一个对象小区。也即，在调度的过程中，各个对象小区均根据参考时域资源分配表格进行配置。
假设第一小区cell1为参考小区。表6示出了参考时域资源分配表格的一种可选的结构。该参考时域资源分配表格包括“TDRA index”列和与“TDRA index”列并列的一个表格区块。表格区块包括时域偏置/SLIV/mapping type等3列，分别用于配置各个小区的时域偏置/SLIV/mapping type信息。以对象小区的数量为2进行说明。如果DCI中时域资源分配指示字段的值为0，则对应于“TDRA index”的值为0的行，则第一小区cell1得到时域资源信息为下一时隙内起始符号为0，长度为14个符号。第二小区cell 2同样得到自己的调度资源为：cell1下一时隙内起始符号为0，长度为14个符号。如果此时cell 1与cell2的子载波间隔不同，则可能出现跨时隙的情况出现，参照图9，此时cell2将在时隙边缘及与调度的方向不同的符号上做分割。也即，如在小区边缘，本来只调度了一个PDSCH，会自动分为2个PDSCH。在调度方向不同符号时(DL(下行)在前UL(上行)在后)，如原PDSCH会只在DL上分一部分，UL部分上为一部分，但是UL不能发PDSCH，就不发了。

在其他可选的实施方式中，参考时域资源分配表格支持大于等于3个对象小区，各个对象小区均参照时域资源分配表格进行配置。
在又一种可选的实施方式中，参考时域资源分配表格的行列的形式是根据表6转置得到的。

实施例11
本实施例提供一种DCI的生成系统。参照图11，该DCI的生成系统包括长度获取单元401、子字段构建单元402、目标DCI生成单元403。
长度获取单元401用于根据与对象小区对应的期望DCI的各个字段的长度得到目标DCI的各个字段的长度，对象小区的数量为多个，期望DCI为用于单独调度每一个对象小区所需的DCI，目标DCI的各个字段的长度为兼容期望DCI的对应字段所需的长度。子字段构建单元402用于根据预设对应关系对目标DCI的各个字段分别构建子字段以使目标DCI的每一个字段的各个子字段分别与一个对象小区相对应。目标DCI生成单元403用于根据目标DCI的各个字段的长度和对应关系生成目标DCI的各个字段以形成目标DCI。
根据每一个对象小区对应的期望DCI的各个字段的长度得到目标DCI的各个字段的长度，可以得到目标DCI的每一个字段具有合适的长度以兼容对应多个小区的相应字段，从而使得每一个字段都能够包含针对多个小区的调度信息，也即，一个DCI能够兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅占用一个PDSCH，节省了PDSCH等通信资源。
实施例12
在实施例11的基础上，本实施例提供一种DCI的生成系统。
作为一种具体的实施方式，长度获取单元401还用于根据期望DCI的对应字段的长度的最大值得到目标DCI的对应字段的长度。
设对象小区的数量为K。根据现有技术，为了分别对K个对象小区进行单独调度时所需要分别设 置的期望DCI，以频域资源分配字段为例，这些期望DCI的频域资源分配字段分别具有与对应的对象小区对应的长度。在一种可选的实施方式中，以这些长度中的最大值作为目标DCI的频域资源分配字段的长度。目标DCI的其他的字段的长度的确定方式与此类似。据此，即可使得生成的目标DCI的长度能兼容多个对象小区的调度信息，从而实现一个目标DCI包含多个对象小区的调度信息以支持同时对多个对象小区进行调度。在另一种可选的实施方式中，目标DCI的频域资源分配字段的长度为这些长度中的最大值与一预设位宽值的和，该预设位宽值对应的子字段，用于对多个对象小区的资源分配类型进行配置。目标DCI的其他的字段的长度的确定方式与此类似。
作为一种可选的实施方式，设目标DCI的某一字段的长度为W位，则该字段包含一个W位的调度信息，该W位的调度信息用于对多个对象小区进行调度。具体实施时，目标DCI通过一个预设的PDCCH发送，该PDCCH对应多个对象小区。多个对象小区收到该目标DCI之后，对该目标DCI进行解析，分别在该目标DCI的该字段得到该W位的调度信息。多个对象小区中，如果某一对象小区对应的期望DCI的该字段具有Y(Y小于等于W)位，则该对象小区以该W位的调度信息中的最低的Y位作为该对象小区对应的子字段作为该对象小区的调度信息。例如，该字段需要W位的对象小区，以该完整字段作为与该对象小区对应的子字段以获得对应的调度信息；该字段需要X(X小于W)位的对象小区，则以该字段中的最低的X位作为与该对象小区对应的子字段以获得对应的调度信息。目标DCI中的其他字段对多个对象小区的作用方式类似。基于此，一个目标DCI即可兼容多个小区的配置信息。
在第一种可选的实施方式中，如果多个对象小区均只支持资源分配类型1，则频域资源分配字段的长度(位数)取决于多个对象小区对应的PRB个数最大的对象小区的BWP(部分带宽)。即，如果多个对象小区均只支持资源分配类型1，则目标DCI的频域资源分配字段的长度为
Figure PCTCN2021075600-appb-000036
其中n∈[1,K]，K为对象小区的数量。
Figure PCTCN2021075600-appb-000037
Figure PCTCN2021075600-appb-000038
分别与每一个对象小区相对应。
在第二种可选的实施方式中，如果多个对象小区均只支持资源分配类型0，则频域资源分配字段的长度取决于多个对象小区对应的N RBG个数最大的对象小区的BWP。即，如果多个对象小区均只支持资源分配类型0，则目标DCI的频域资源分配字段的长度为max(N(n) RBG)，其中，n∈[1,K]，K为对象小区的数量。
Figure PCTCN2021075600-appb-000039
分别与每一个对象小区相对应。
在第三种可选的实施方式中，如果多个对象小区中，一部分对象小区只支持资源分配类型0，另一部分对象小区只支持资源分配类型1，则频域资源分配字段的长度为：
Figure PCTCN2021075600-appb-000040
其中，
Figure PCTCN2021075600-appb-000041
分别与只支持资源分配类型1的一部分对象小区中的每一个对象小区相对应，N(j) RBG分别与只支持资源分配类型0的一部分对象小区中的每一个对象小区相对应。作为一种可选的实施方式，多个对象小区中，只支持资源分配类型0的一部分对象小区的数量为L，只支持资源分配类型1的另一部分对象小区的数量为M(L+M＝K，K为期望调度的对象小区的数量，L、M、K均为正整数)，则i∈[1,L],j∈[1,M]。
在第四种可选的实施方式中，如果多个对象小区均既支持资源分配类型0又支持资源分配类型1， 则目标DCI的频域资源分配字段包括一位类型指示位，类型指示位用于指示对象小区均为资源分配类型1或均为资源分配类型0，则频域资源分配字段的长度为
Figure PCTCN2021075600-appb-000042
其中，
Figure PCTCN2021075600-appb-000043
与对象小区均被指示为资源分配类型1的模式相对应；N(n) RBG与对象小区均被指示为资源分配类型0的模式相对应，K为对象小区的数量。作为一种可选的实施方式，DCI的频域资源分配字段的最高位(MSB)作为类型指示位。当类型指示位的值为0时，各个对象小区均被指示为资源分配类型0；当类型指示位的值为1时，各个对象小区均被指示为资源分配类型1。
在第五种可选的实施方式中，目标DCI的频域资源分配字段包括K位类型指示位，每一位类型指示位分别对应一个对象小区以指示对象小区资源分配类型1或资源分配类型0，则频域资源分配字段的长度为
Figure PCTCN2021075600-appb-000044
Figure PCTCN2021075600-appb-000045
其中，
Figure PCTCN2021075600-appb-000046
与对象小区均被指示为资源分配类型1的模式相对应；N(n) RBG与对象小区均被指示为资源分配类型0的模式相对应，K为对象小区的数量。在作为一种可选的实施方式，DCI的频域资源分配字段的最高的K位均为类型指示位。其中，频域资源分配字段的最高位与第一个对象小区相对应，当该位的值为0时，第一个对象小区被指示为资源分配类型0；当该位的值为1时，第一个对象小区被指示为资源分配类型1；如果第一个对象小区仅支持资源分配类型0或者第一个对象小区仅支持资源分配类型1，则第一个对象小区忽略该位，其资源分配类型不受该位的影响。频域资源分配字段的第二高位与第二个对象小区相对应，当该位的值为0时，第二个对象小区被指示为资源分配类型0；当该位的值为1时，第二个对象小区被指示为资源分配类型1；如果第二个对象小区仅支持资源分配类型0或者第二个对象小区仅支持资源分配类型1，则第二个对象小区忽略该位，其资源分配类型不受该位的影响。依此类推，频域资源分配字段的第K高位与第K个对象小区相对应，当该位的值为0时，第K个对象小区被指示为资源分配类型0；当该位的值为1时，第K个对象小区被指示为资源分配类型1；如果第K个对象小区仅支持资源分配类型0或者第K个对象小区仅支持资源分配类型1，则第K个对象小区忽略该位，其资源分配类型不受该位的影响。
根据期望DCI的对应字段的长度的最大值得到目标DCI的对应字段的长度，使得目标DCI的对应字段通过较短的长度即可兼容需要调度的所有多个对象小区，节省了资源。
本实施例的DCI的生成系统通过对目标DCI的长度及相应字段所包含的信息的合理设置，使得一个目标DCI兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅占用一个PDSCH，节省了PDSCH等通信资源。
实施例13
在实施例11的基础上，本实施例提供一种DCI的生成系统。在本实施例中，作为一种具体的实施方式，长度获取单元401还用于根据多个期望DCI的对应字段的长度的和得到目标DCI的对应字段的长度。
设对象小区的数量为K。根据现有技术，为了分别对K个对象小区进行单独调度时所需要分别设置的期望DCI，以频域资源分配字段为例，这些期望DCI的频域资源分配字段分别具有与对应的对象 小区对应的长度。设第i个对象小区的期望DCI的频域资源分配字段的长度为W i(i∈[1,K])。
在一种可选的实施方式中，目标DCI的频域资源分配字段的长度
Figure PCTCN2021075600-appb-000047
频域资源分配字段中，最低的W 1位(即频域资源分配字段第W 1位至第1位，第1位为频域资源分配字段的最低位)构成第一子字段，第一子字段与第一对象小区相对应；与第一子字段相邻的W 2位(即频域资源分配字段第(W 1+W 2)位至第(W 1+1)位)构成第二子字段，第二子字段与第二对象小区相对应。依此类推，频域资源分配字段的最高W K位构成第K子字段，第K子字段与第K对象小区相对应。多个对象小区接收到该目标DCI之后，从目标DCI中解析出频域资源分配字段，并根据预设对应关系从频域资源分配字段中的对应子字段获得对应的配置信息。目标DCI的其他的字段的长度的确定方式和作用方式与此类似。据此，即可使得生成的目标DCI的长度能兼容多个对象小区的调度信息，从而实现一个目标DCI包含多个对象小区的调度信息以支持同时对多个对象小区进行调度。
在另一种可选的实施方式中，目标DCI的频域资源分配字段的长度
Figure PCTCN2021075600-appb-000048
频域资源分配字段中，最低的W 1位(即频域资源分配字段第W 1位至第1位，第1位为频域资源分配字段的最低位)构成第一子字段，第一子字段与第一对象小区相对应；与第一子字段相邻的W 2位(即频域资源分配字段第(W 1+W 2)位至第(W 1+1)位)构成第二子字段，第二子字段与第二对象小区相对应。依此类推，频域资源分配字段的第
Figure PCTCN2021075600-appb-000049
位至第
Figure PCTCN2021075600-appb-000050
位构成第K子字段，第K子字段与第K对象小区相对应。频域资源分配字段的最高的A位用于对多个对象小区的资源分配类型进行配置。目标DCI的其他的字段的长度的确定方式和作用方式与此类似。
根据多个期望DCI的对应字段的长度的和得到目标DCI的对应字段的长度，可以使与每一个对象小区对应的子字段相对独立，所以，对某一个对象小区的配置不会受到其他小区的配置的影响或限制，具有较高的灵活性。
本实施例的DCI的生成系统通过对目标DCI的长度及相应字段所包含的信息的合理设置，使得一个目标DCI兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅占用一个PDSCH，节省了PDSCH等通信资源。
实施例14
在实施例11的基础上，本实施例提供一种DCI的生成系统。参照图12，该DCI的生成系统还包括参考设置单元404。参考设置单元404用于将其中一个对象小区设置为参考小区。则长度获取单元401用于根据参考小区的期望DCI的各个字段的长度得到目标DCI的各个字段的长度。子字段构建单元402还用于将目标DCI的每一个字段同时与多个对象小区相对应。目标DCI生成单元403还用于将与参考小区对应的期望DCI作为目标DCI。也即，在对多个对象小区进行调度时，参考小区以外的其他各个对象小区均采用与参考小区相同的配置。
具体实施时，目标DCI(即与参考小区对应的期望DCI)通过一个预设的PDCCH发送，该PDCCH对应多个对象小区。多个对象小区收到该目标DCI之后，对该目标DCI进行解析，即可得到对应的配置信息。根据本实施例的DCI的生成系统，一个DCI能够兼容多个小区的调度信息，从而支持同时对多个小区进行调度。在进行多个小区的调度的过程中，只需要生成并发送一个目标DCI即可，仅 占用一个PDSCH，节省了PDSCH等通信资源。
实施例15
本实施例提供一种小区的调度系统。参照图13，包括调度单元405405和实施例11-13中任意一个实施例的DCI的生成系统5。
DCI的生成系统5用于生成目标DCI；调度单元405用于根据目标DCI调度多个对象小区。
目标DCI能够兼容多个对象小区的调度信息，所以，通过一个目标DCI即可支持同时对多个目标小区的调度。根据目标DCI调度多个对象小区，仅占用一个PDSCH，节省了PDSCH等通信资源。
实施例16
在实施例15的基础上，本实施例提供一种小区的调度系统。参照图14，小区的调度系统还包括表格构建单元406。表格构建单元406用于构建部分带宽配置表格，部分带宽配置表格包括与每一个对象小区对应的部分带宽配置信息；则调度单元405还用于根据目标DCI的部分带宽指示字段查询部分带宽配置表格以获得与每一个对象小区对应的部分带宽配置信息，根据部分带宽配置信息配置对应的对象小区。
在第一种可选的实施方式中，部分带宽配置表格由高层信令(RRC)信令配置。以对象小区的数量为2的情形为例，参照表1，部分带宽配置表格的第一列为索引列，第二列为第一小区cell1对应的部分带宽配置信息，第三列为第二小区cell2对应的部分带宽配置信息。当DCI的部分带宽指示字段的值为1时，对应部分带宽配置表格中部分带宽配置索引的值为1的行，因此，第一小区cell1对应的部分带宽配置信息为1，第二小区cell2对应的部分带宽配置信息为1。第一小区cell1和第二小区cell2根据部分带宽配置信息进行BWP切换。部分带宽配置信息的具体含义是本领域技术人员清楚的，此处不再赘述。
在其他可选的实施方式中，部分带宽配置表格支持大于等于3个对象小区，部分带宽配置表格的列数与对象小区的数量相适应。
在另一种可选的实施方式中，采用的部分带宽配置表格的行列的形式是根据表1转置得到的。
在第二种可选的实施方式中，为了提高BWP切换的效率，部分带宽配置信息包括激活模式，激活模式用于指示对象小区保持当前的BWP。参照表2，该激活模式值采用“active BWP”表征，表示不进行BWP切换，仍然使用当前的BWP。其益处在于，可以采用单小区PDCCH进行单个小区的BWP切换，而多小区PDCCH的部分或全部BWP均是针对当前BWP进行调度，不需要进一步调整激活BWP，有助于提高BWP切换的效率。根据表2，当DCI的部分带宽指示字段的值为1时，对应部分带宽配置表格中部分带宽配置索引的值为1的行，因此，第一小区cell1对应的部分带宽配置信息为“active BWP”，第一小区cell1仍然使用当前的BWP；第二小区cell2对应的部分带宽配置信息为1，第二小区cell2根据部分带宽配置信息进行BWP切换。
在其他可选的实施方式中，部分带宽配置表格支持大于等于3个对象小区，部分带宽配置表格的列数与对象小区的数量相适应。
在另一种可选的实施方式中，采用的部分带宽配置表格的行列的形式是根据表2转置得到的。
通过部分带宽配置表格的设置，本实施例的小区的调度系统在对多个小区进行调度时，可以同时对多个小区的部分带宽进行配置，提高了效率。
实施例17
在实施例15的基础上，本实施例提供一种小区的调度系统。参照图14，小区的调度系统还包括表格构建单元406。在一种可选的实施方式中，表格构建单元406用于构建时域资源分配表格，时域资源分配表格包括分别与每一个对象小区对应的时域资源配置信息；则调度单元405还用于根据目标DCI的时域资源分配字段查询时域资源分配表格以获得与每一个对象小区对应的时域资源配置信息，根据时域资源配置信息配置对应的对象小区。
在第一种可选的实施方式中，时域资源分配表格包括索引区和多个表格区块；每一个表格区块分别与一个对象小区相对应；索引区的每一个元素分别用于同时索引多个表格区块的对应元素以获取时域资源配置信息。在步骤S1032中，根据索引区的与时域资源分配字段对应的元素同时索引多个表格区块的对应元素以获取时域资源配置信息。
具体参照表3，时域资源分配表格为单一表格。时域资源分配表格中“TDRA index(时域资源分配索引)”列作为索引区。该时域资源分配表格的第2-5列构成第一表格区块，与第一小区cell1相对应。其中，第2列“K0(DL)or K2(UL)(时域偏置)for cell 1”列包括时域偏置信息，“SLIV for cell 1”列包括SLIV配置信息，“Mapping type for cell 1”列包括映射类型配置信息，“Repetition for cell 1”列包括重传配置信息。该时域资源分配表格的第6-9列构成第二表格区块，与第二小区cell2相对应。第二表格区块的结构与第一表格区块类似。
“TDRA index”列的每一行对应的数值分别为0至15的16个整数。TDRA index的值以及对应的时域偏置/SLIV/mapping type/repetition的数值与现有技术中相似，所以，表3省略了个别行为示出。
目标DCI生成后，根据目标DCI的时域资源分配字段对应的数值(对应TDRA index的值)在时域资源分配表格中查询得到每一个小区的时域资源配置信息。例如，目标DCI的时域资源分配字段的数值为1，则根据时域资源分配表格中TDRA index的值为1的行得到各个小区的时域资源配置信息。
在其他可选的实施方式中，时域资源分配表格支持大于等于3个对象小区，时域资源分配表格包含的表格区块的数量与对象小区的数量相适应。
在另一种可选的实施方式中，采用的时域资源分配表格的行列的形式是根据表3转置得到的。
在第二种可选的实施方式中，时域资源分配表格包括多个子表格；每一个子表格均包括一个索引区和一个表格区块，每一个表格区块分别与一个对象小区相对应，索引区的每一个元素分别用于索引对应的表格区块的对应元素以获取时域资源配置信息。则在步骤1032中，根据索引区的与时域资源分配字段对应的元素索引表格区块的对应元素以分别获取与每一个对象小区对应的时域资源配置信息。
当对象小区的数量为2时，时域资源分配表格包括2个子表格。2个子表格分别参照表4、表5。第一子表格(表4)与第一小区cell1相对应，第二子表格(表5)与第二小区cell2相对应。
第一子表格中，“TDRA index”列作为索引区，第2-4列构成第一表格区块，与第一小区cell1相 对应。其中，第2列“K0(DL)or K2(UL)(时域偏置)”列包括时域偏置信息，“SLIV”列包括SLIV配置信息，“Mapping type”列包括映射类型配置信息，“Repetition for cell 1”列包括重传配置信息。第一表格区块包括时域偏置/SLIV/mapping type/repetition等4列，分别用于配置第一小区cell1的时域偏置/SLIV/mapping type/repetition信息。第二子表格的结构与第一子表格类似，“TDRA index”列作为索引区，第2-4列构成第二表格区块，与第二小区cell1相对应。
目标DCI生成后，根据目标DCI的时域资源分配字段的数值(对应TDRA index的值)分别在每一个子表格中查询得到该小区的时域资源配置信息。例如，目标DCI的时域资源分配字段的数值为1，则根据第一子表格中TDRA index的值为1的行得到第一小区cell1的时域资源配置信息，根据第二子表格中TDRA index的值为1的行得到第二小区cell2的时域资源配置信息。
在其他可选的实施方式中，时域资源分配表格支持大于等于3个对象小区，时域资源分配表格包含的子表格的数量与对象小区的数量相适应。
在另一种可选的实施方式中，时域资源分配表格的子表格的行列的形式是根据表4、表5转置得到的。
“TDRA index”列的每一行对应的数值分别为0至15的16个整数。TDRA index的值以及对应的时域偏置/SLIV/mapping type的数值与现有技术中相似，所以，表4、表5均省略了个别行为示出。
在另一种可选的实施方式中，表格构建单元406用于构建时域资源分配表格和部分带宽配置表格。则调度单元405还用于根据目标DCI的时域资源分配字段查询时域资源分配表格以获得与每一个对象小区对应的时域资源配置信息，根据目标DCI的部分带宽指示字段查询部分带宽配置表格以获得与每一个对象小区对应的部分带宽配置信息，根据部分带宽配置信息和时域资源配置信息配置对应的对象小区。
本实施例的小区的调度系统通过对时域资源分配表格的改进，可以通过一个DCI实现同时对多个小区的调度，节省了PDSCH等通信资源。
实施例18
本实施例提供一种小区的调度系统。参照图15，该小区的调度系统包括调度单元405和实施例14的DCI的生成系统6。DCI的生成系统6用于生成目标DCI；调度单元405用于根据目标DCI调度多个对象小区。
在一种可选的实施方式中，该小区的调度系统还包括表格构建单元406。表格构建单元406用于构建参考时域资源分配表格，参考时域资源分配表格包括与参考小区相对应的时域资源配置信息。则调度单元405还用于根据目标DCI的时域资源分配字段查询参考时域资源分配表格以获得时域资源配置信息，根据时域资源配置信息配置每一个对象小区。
假设第一小区cell1为参考小区。表6示出了参考时域资源分配表格的一种可选的结构。该参考时域资源分配表格包括“TDRA index”列和与“TDRA index”列并列的一个表格区块。表格区块包括时域偏置/SLIV/mapping type等3列，分别用于配置各个小区的时域偏置/SLIV/mapping type信息。以对象小区的数量为2进行说明。如果DCI中时域资源分配指示字段的值为0，则对应于“TDRA index” 的值为0的行，则第一小区cell1得到时域资源信息为下一时隙内起始符号为0，长度为14个符号。第二小区cell 2同样得到自己的调度资源为：cell1下一时隙内起始符号为0，长度为14个符号。如果此时cell 1与cell2的子载波间隔不同，则可能出现跨时隙的情况出现，参照图9，此时cell2将在时隙边缘及与调度的方向不同的符号上做分割。也即，如在小区边缘，本来只调度了一个PDSCH，会自动分为2个PDSCH。在调度方向不同符号时(DL(下行)在前UL(上行)在后)，如原PDSCH会只在DL上分一部分，UL部分上为一部分，但是UL不能发PDSCH，就不发了。
在其他可选的实施方式中，参考时域资源分配表格支持大于等于3个对象小区，各个对象小区均参照时域资源分配表格进行配置。
在又一种可选的实施方式中，参考时域资源分配表格的行列的形式是根据表6转置得到的。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
