具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地 理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示，本公开的实施例提供一种频域资源分配方法，应用于网络侧设备，所述方法包括：
步骤11，向终端发送下行控制信息DCI，所述DCI用于指示物理共享信道的频域资源分配，所述物理共享信道的频域资源位于一个或多个频域资源范围内。
该实施例中，可以向终端发送下行控制信息(Downlink Control Information，DCI)，所述DCI用于指示物理共享信道的频域资源分配，所述物理共享信道的频域资源位于一个或多个频域资源范围内。实现多个不同的频域资源范围在一个DCI中调度，提高载波使用的吞吐量，降低下行控制信道PDCCH的开销。
在本公开的一可选地实施例中，步骤11中，所述DCI包括第一信息域和第二信息域；
所述第一信息域用于指示物理共享信道的频域资源位于的一个或多个频域资源范围的索引；
所述第二信息域用于指示在一个频域资源范围内的频域资源分配。
所述频域资源范围为载波或带宽部分(Bandwidth Part，BWP)。
该实施例中，第二信息域具体用于指示物理下行共享信道(Physical Downlink Shared Channel，PDSCH)/物理上行共享信道PUSCH的频域资源在一个载波或者带宽部分BWP内的资源分配。第二信息域对于多个频域资源范围是共享的，也即是多个频域资源范围内都参考第二信息域指示的频域资源分配，节省了PDCCH的负荷大小，提升PDCCH的吞吐量。
在本公开的又一可选地实施例中，所述第一信息域中采用位图(bitmap)或者代码点(codepoint)的方法指示所述一个或多个频域资源范围的索引。
该实施例中，所述第一信息域中采用位图(bitmap)或者代码点(codepoint)的方法指示实际调度的物理下行共享信道PDSCH/物理上行共享信道PUSCH所在的至少一个频域资源的索引。例如，有五个载波/带宽部分BWP，可以利用5位图(5bitmap)指示调度的是哪些载波/带宽部分BWP。
在实际调度至少两个目标频域资源时，还可以提取在基站配置一些载波/ 带宽部分BWP的组合配置情况，然后通过第一信息域指示组合或者配置索引。
在本公开的又一可选地实施例中所述频域资源范围包括：带宽最小的第一频域资源范围以及除所述第一频域资源范围以外的至少一个第二频域资源范围。
该实施例中，所述第一频域资源范围是至少两个频域资源范围中带宽最小的频域资源范围。
在本公开的又一可选地实施例中，所述第二信息域的比特长度等于根据第一频域资源范围的带宽确定的资源分配的比特长度。
该实施例中，终端结合第一信息域和第二信息域，确定调度的至少一个频域资源范围，以及在调度的频域资源范围上的频域资源分配，其中，调度的多个频域资源范围内的物理信道的频域资源分配均参考第二信息域的指示。考虑到多个频域资源范围的带宽大小可以不同，该实施例中第二信息域的长度根据最小的频域资源范围的带宽确定，也即是无论第一信息域指示的调度的频域资源范围的索引是任何组合，第二信息域的大小都是固定的，所述DCI的负荷大小也是固定的，简化终端接收PDCCH的复杂度。
在本公开的又一可选地实施例中，所述频域资源分配是类型1时(例如，连续资源分配时)，所述第二信息域包含的资源指示值(Resource Indication Value，RIV)对应的第二频域资源范围的起始资源块(Resource Block，RB)为：
Figure PCTCN2022131738-appb-000017
连续分配的RB数量为
Figure PCTCN2022131738-appb-000018
其中，
Figure PCTCN2022131738-appb-000019
是第一频域资源范围的带宽大小/物理资源块(Physical Resource Block，PRB)数量；
K是根据第二频域资源范围与第一频域资源范围的带宽的比值，例如
Figure PCTCN2022131738-appb-000020
该实施例中，第一信息域中指示的调度频域资源范围包括第二频域资源范围，对于第二频域资源范围，通过上述方法确定所述第二频域资源范围内调度的物理下行共享信道PDSCH或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)占用的频域资源位置。
如果第一信息域中指示的调度频域资源范围包括第一频域资源范围，对于第一频域资源范围，则按照相关方法确定所述第一频域资源范围内调度的物理下行共享信道PDSCH或物理上行共享信道PUSCH占用的频域资源位置。
在本公开的再一可选地实施例中，所述频域资源分配是类型0时(例如，不连续资源分配时)，所述第二信息域的比特对应所述第二频域资源范围的资源块组(Resource block group，RBG)，其中，
第一个RBG的大小为
Figure PCTCN2022131738-appb-000021
如果
Figure PCTCN2022131738-appb-000022
最后一个RBG的大小为
Figure PCTCN2022131738-appb-000023
否则最后一个RBG的大小为P*K；其他RBG大小为P*K；
其中，P是第一频域资源范围的RBG的大小，K是根据第二频域资源范围与第一频域资源范围的带宽的比值；
Figure PCTCN2022131738-appb-000024
为第二频域资源范围中的起始资源位置，
Figure PCTCN2022131738-appb-000025
为第二频域资源范围的带宽大小/物理资源块PRB数量。
该实施例中，第一信息域中指示的调度频域资源范围包括第二频域资源范围，对于第二频域资源范围，通过上述方法确定所述第二频域资源范围内调度的物理下行共享信道PDSCH或物理上行共享信道PUSCH占用的频域资源位置。
如果第一信息域中指示的调度频域资源范围包括第一频域资源范围，对于第一频域资源范围，则按照预设方法确定所述第一频域资源范围内调度的物理下行共享信道PDSCH或物理上行共享信道PUSCH占用的频域资源位置。
如图2至图4所示，目前NR网络存在许多非连续的较小带宽的频谱，图2至图4分别示出了三种带宽的载波/带宽部分BWP示意图，对于由这种多个非连续的小载波/BWP，可以通过一个DCI调度，从而可以实现一个物理下行共享信道PDSCH或者物理上行共享信道PUSCH可以映射在至少一个非连续的频域资源上。
例如，基站向终端发送DCI，所述DCI用于调度物理下行共享信道PDSCH或物理上行共享信道PUSCH，DCI的第一信息域指示的频域资源范围含有图2、图3和图4所示的载波/带宽部分BWP中的至少一个，终端会结合第一信息域和第二信息域，确定调度的至少一个频域资源范围，以及在调度的频域 资源范围上的频域资源分配比特长度和在调度的频域资源范围内的频域资源分配位置。
这里，第一频域资源范围可以是如图2所示的载波，第二频域资源范围可以是如图3或者图4所示的载波/BWP，第一频域资源范围是至少一个频域资源范围中带宽最小的频域资源范围；DCI的第二信息域指示这些调度的频域资源在分配时，按照第一频域资源范围的带宽进行分配，即按照10M的带宽进行分配，也就是说，所述频域资源分配的比特长度，等于根据第一频域资源范围确定的频域资源指示的比特长度；
那么，对于如图3和图4所示的第二频域资源范围，如果第一信息域指示调度的频域资源范围包括图3和/或图4所述的频域资源范围，则需要按照10兆赫(MHz)的频域资源分配的比特长度，对20MHz和30MHz的频域资源进行映射，具体映射时，
1)对于资源分配类型1(连续资源分配)：
终端对第二信息域指示的RIV(资源指示值)进行解释，其中RIV对应的起始RB为

是第一频域资源范围的带宽大小/PRB数量；K是根据第二频域资源范围与第一频域资源范围的带宽的比值，例如
Figure PCTCN2022131738-appb-000029
例如，对于图3的频域资源范围，K＝2；对于图4的频域资源范围，K＝3。
2)对于资源分配类型0(非连续资源分配)
终端对第二信息域指示的bitmap进行解释，
所述第二信息域的比特对应所述第二频域资源范围的资源块组RBG，其中，第一个RBG的大小为

如果
Figure PCTCN2022131738-appb-000031
最后一个RBG的大小为
Figure PCTCN2022131738-appb-000032
否则最后一个RBG的大小为P*K；其余RBG大小为P*K；
其中，P是第一频域资源范围的RBG的大小，K是根据第二频域资源范围与第一频域资源范围的带宽的比值，
Figure PCTCN2022131738-appb-000033
或

为第二频域资源范围中的起始资源位置，
Figure PCTCN2022131738-appb-000036
为第二频域资 源范围的带宽大小/物理资源块PRB数量。
例如，对于图3的频域资源范围，K＝2；对于图4的频域资源范围，K＝3。
这样既可以通过多个载波的使用提高吞吐量，实现一个TB包在非连续的频域资源上的映射，降低终端处理多个TB包的复杂度，也可以避免增加一次新的物理下行控制信道PDCCH。同时终端向基站发送的物理上行共享信道PUSCH，也可以和所述物理下行共享信道PDSCH映射在一个频域资源上。
本公开的上述实施例中，通过向终端发送下行控制信息DCI，所述DCI用于指示物理共享信道的频域资源分配，所述物理共享信道的频域资源位于一个或多个频域资源范围内。可以减少DCI降低网络侧信令开销的同时，实现灵活的单/多载波/频域资源/BWP调度，实现一个TB包在非连续的频域资源上的映射，降低终端处理多个TB包的复杂度。同时通过第一频域资源范围和第二频域资源范围的定义，确定第二信息域的长度，降低不同的DCI的负荷大小的数量，降低终端检测PDCCH的复杂度。
本公开的实施例还提供一种频域资源指示的接收方法，应用于终端，所述方法包括：
