本申请主张在2020年4月3日在中国提交的中国专利申请号No.202010261429.1的优先权，其全部内容通过引用包含于此。
技术领域
本发明实施例涉及通信技术领域，具体涉及一种频域资源指示的方法及设备。
背景技术
在新空口(New Radio，NR)***中，通过下行控制信息(Downlink Control Information，DCI)中的频域资源分配(Frequency Domain Resource Allocation，FDRA)域指示，频域资源调度有类型0(type 0)和类型1(type 1)。
在Type 0频域资源分配方法中按照带宽部分(Bandwidth Part，BWP)大小(BWP中的物理资源块(Physical Resource Block，PRB)数目)来划分资源块组(Resource Block Group，RBG)大小，参见表1。
表1：
Figure PCTCN2021084490-appb-000001
每个RBG用1比特指示是否被占用，比如：BWP大小是36个PRB，按照表格中的配置1：一个RBG大小是2，共有18个RBG，也就是用DCI中用18比特指示频域资源，比如某个比特为“1”表示本次调度该RBG分配给该终端，该比特为“0”表示本次调度该RBG没有分配给该终端。
在Type 1频域资源分配方法中指示资源指示值(Resource Indication Value， RIV)来指示频域资源分配，RIV指示所分配的起始PRB位置和连续分配的PRB个数。
在多传输点(multi TRP)多个下行控制信息(Downlink Control Information，DCI)调度同一个用户设备(User Equipment，UE)时，可以在一个时隙(slot)内频分多路复用(Frequency-division multiplexing，FDM)方式调度，比如，两个传输点(TRP1，TRP2)调度一个UE时，两个传输点需要分别发送DCI1和DCI2，被调度的时域资源信息由TRP1和TRP2分别在DCI1和DCI2中发给UE。
由此可知，现有的频域资源指示方式开销较大。
发明内容
本发明实施例的一个目的在于提供一种频域资源指示的方法及设备，解决现有的频域资源指示方式开销较大的问题。
第一方面，本发明实施例提供一种频域资源指示的方法，应用于终端，所述方法包括：
接收第一信息，所述第一信息用于指示在M个频域资源组中的至少一个频域资源组中为所述终端分配的频域资源；
其中，所述M个频域资源组包括N个频域资源，所述N和M均为大于或等于2的正整数。
第二方面，本发明实施例还提供一种频域资源指示的方法，应用于网络设备，所述方法包括：
发送第一信息，所述第一信息用于指示在M个所述频域资源组中的至少一个频域资源组中为所述终端分配的频域资源；
其中，所述M个频域资源组包括N个频域资源，所述N和M均为大于或等于2的正整数。
第三方面，本发明实施例还提供一种终端，包括：
接收模块，用于接收第一信息，所述第一信息用于指示在M个频域资源组中的至少一个频域资源组中为所述终端分配的频域资源；
其中，所述M个频域资源组包括N个频域资源，所述N和M均为大于 或等于2的正整数。
第四方面，本发明实施例还提供一种网络设备，包括：
发送模块，用于发送第一信息，所述第一信息用于指示在M个所述频域资源组中的至少一个频域资源组中为所述终端分配的频域资源；
其中，所述M个频域资源组中包括N个频域资源，所述N和M均为大于或等于2的正整数。
第五方面，本发明实施例还提供一种通信设备，包括：处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序，所述程序被所述处理器执行时实现如第一方面或第二方面所述的频域资源指示的方法步骤。
第六方面，本发明实施例还提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现如第一方面或第二方面所述的频域资源指示的方法的步骤。
第七方面，本发明实施例还提供一种计算机程序产品，所述计算机程序产品被存储在非易失的存储介质中，所述程序产品被配置成被至少一个处理器执行以实现如第一方面或第二方面所述的频域资源指示的方法的步骤。
在本发明实施例中，在单个传输点(single TRP)传输情况下的频域资源分配方式中，由于单个传输点下发的第一信息可以指示在一个或多个频域资源组中为终端分配的频域资源，而不需要指示所有频域资源中的每个频域资源是否分配给该终端，这样可以减少第一信息中的信息位的数量，节省网络侧下发控制信息的开销。同样在多个传输点(multi TRP)传输情况下的频域资源分配方式中，由于第一信息可以指示多个传输点在一个或多个频域资源组中为终端分配的频域资源，而不用每个传输点均下发控制信息指示频域资源分配的情况，这样可以减少网络侧下发控制信息的开销。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。

本文所描述的技术不限于长期演进型(Long Time Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)***，并且也可用于各种无线通信***，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他***。
术语“***”和“网络”常被可互换地使用。CDMA***可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA***可实现诸如全球移动通信***(Global System for Mobile Communications，GSM)之类的无线电技术。OFDMA***可实现诸如超移动宽带(Ultra Mobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(无线保真(Wireless Fidelity，Wi-Fi))、IEEE 802.16(全球微波接入互操作性(Worldwide Interoperability for Microwave Access，WiMAX))、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信***(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的***和无线电技术，也可用于其他***和无线电技术。
下面结合附图介绍本发明的实施例。本发明实施例提供的一种频域资源指示的方法及设备可以应用于无线通信***中。参考图1，为本发明实施例提供的一种无线通信***的架构示意图。如图1所示，该无线通信***可以包括：网络设备10、网络设备11和终端12，终端12可以记做UE12，终端12可以与网络设备10、网络设备11通信(传输信令或传输数据)。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。
本发明实施例提供的网络设备10、网络设备11可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为第五代(5 th Generation，5G)***中的网络设备(例如，下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))等设备。
本发明实施例提供的终端12可以为手机、平板电脑、笔记本电脑、超级 移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。
参见图2，本发明实施例还提供一种频域资源指示的方法，该方法的执行主体可以为终端，所述方法包括：步骤201。
步骤201：接收第一信息，所述第一信息用于指示在M个频域资源组中的至少一个频域资源组中为所述终端分配的频域资源。
其中，所述M个频域资源组包括N个频域资源，也就是，每个所述频域资源组中包括至少一个频域资源，所述至少一个频域资源选自N个频域资源，所述N和M均为大于或等于2的正整数；
可选地，频域资源可以是资源块组(Resource block group，RBG)，比如将11个RBG划分为2个频域资源组，其中一个频域资源组中包括6个RBG，另一个频域资源组中包括5个RBG。
可选地，频域资源可以是带宽部分(Bandwidth Part，BWP)中的物理资源块(Physical Resource Block，PRB)，比如，将一个BWP中的36个PRB划分为2个频域资源组，其中一个频域资源组中包括18个PRB，另一个频域资源组中包括18个PRB，上述频域资源组也可以称为子带宽部分(sub-BWP)。
当然可以理解的是，在本发明实施例对频域资源的数量以及频域资源组的数量不做具体限定。
可选地，频域资源组的分组方式是协议约定或者网络侧配置的。
比如：分组方式包括但不限于以下几种：(1)按照频域资源的数量分组，比如频域资源的总数量为11个，一组的频域资源的数量为6个，另一组频域资源的数量为5个；(2)按照频域资源编号分组，比如，编号为奇数的频域资源为一组，编号为偶数的频域资源为另一组；又比如，频域资源的总数量为11个，编号前6个频域资源为一组，编号后5个频域资源为另一组，此种方式也可称为连续编号分组。
可以理解的是，在本发明实施例对频域资源的分组方式不做具体限定。
上述网络设备也可以称为收发节点(Transmission and Reception Point，TRP)，或传输点。
可以理解的是，在单个传输点(single TRP)传输情况下的频域资源分配方式中，由于单个传输点下发的第一信息可以指示在一个或多个频域资源组中为终端分配的频域资源，而不需要指示所有频域资源中的每个频域资源是否分配给该终端，这样可以减少第一信息中的信息位的数量，节省网络侧下发控制信息的开销。
可以理解的是，在多个传输点(multi TRP)传输情况下的频域资源分配方式中，由于第一信息可以指示多个传输点在一个或多个频域资源组中为终端分配的频域资源，而不用每个传输点均下发控制信息指示频域资源分配的情况，这样可以减少网络侧下发控制信息的开销。
可选地，第一信息可以为下行控制信息(Downlink Control Information，DCI)，当然并不限于此。
在本发明实施例中，第一信息、网络设备和频域资源组中的至少两项具有对应关系。
比如，网络设备和第一信息具有对应关系，也就是终端接收到第一信息之后，即可根据第一信息确定是哪个网络设备通过频域资源组为终端分配频域资源。
比如，网络设备和频域资源组具有对应关系，也就是终端接收到来自网络设备的第一信息之后，即可根据第一信息确定是网络设备通过哪个频域资源组为终端分配频域资源。
比如，第一信息和频域资源组具有对应关系，也就是终端接收到来自网络设备的第一信息之后，即可根据第一信息确定是网络设备通过哪个频域资源组为终端分配频域资源。
可以理解的是，第一信息、网络设备和频域资源组中的至少两项具有的对应关系可以由协议约定，或者通过终端确定，或者由网络侧配置。
比如，第一信息可以指示网络设备1在频域资源组1中为终端分配的频域资源；又比如，第一信息指示网络设备1在频域资源组1中为终端分配的频域资源，以及指示网络设备2在频域资源组2中为终端分配的频域资源。由于是将终端的多个频域资源(比如所有频域资源)分成多个组，然后通过第一信息指示一个或多个网络设备在对应频域资源组中为终端分配的频域资 源，这样可以减少第一信息中指示分配频域资源的信息位的个数，有效降低频域资源指示开销。
在一些实施方式中，所述第一信息包括：频域资源分配(Frequency Domain Resource Allocation，FDRA)域，所述频域资源分配域包括：至少一个资源分配位图(bitmap)，所述资源分配位图用于指示：在一个或多个频域资源组中为所述终端分配的频域资源，进一步地，所述资源分配位图中信息位的数量等于
Figure PCTCN2021084490-appb-000002
即频域资源分配域的大小等于
Figure PCTCN2021084490-appb-000003
其中
Figure PCTCN2021084490-appb-000004
表示向上取整，比如，
Figure PCTCN2021084490-appb-000005
可以理解的是，对于N个频域资源，按照现有的频域资源指示方式则需要配置N比特位图，而在本发明实施例中，只需配置M个资源分配位图，每个资源分配位图中的信息位(或者称为比特位)的个数小于N。
在本发明实施例中，资源分配位图、使用资源分配位图分配频域资源的网络设备和频域资源组中的至少两项具有对应关系。
示例性地，资源分配位图与使用资源分配位图分配频域资源的网络设备具有对应关系。比如，多个网络设备同时调度同一个终端时，每个网络设备只通过对应的资源分配位图指示在对应的频域资源组中分配频域资源。
可以理解的是，资源分配位图与分配频域资源的网络设备的对应关系可以由协议约定，或者由终端确定，或者由网络侧配置，比如，终端可以根据预设规则确定资源分配位图与网络设备的对应关系，该预设规则设置为：第一个网络设备对应第一个资源分配位图，第二个网络设备对应的资源分配位图是第一个资源分配位图加上一个偏移值。
可选地，资源分配位图、使用资源分配位图分配频域资源的网络设备和频域资源组中至少两项的对应关系可以通过网络侧配置。
比如，在第一信息中还可以包括：第一指示信息；该所述第一指示信息指示以下至少一项：(1)所述资源分配位图与分配频域资源的网络设备的对应关系；(2)所述资源分配位图与频域资源组的对应关系；(3)分配频域资源的网络设备与频域资源组的对应关系。
进一步地，可选地，第一指示信息包括：一个信息位或多个信息位，比如，用一个比特指示或多个比特联合编码指示：资源分配位图与网络设备的 对应关系；和/或，所述资源分配位图与频域资源组的对应关系，比如一个资源分配位图对应多个频域资源组。
可以理解的是，上述一个比特或者多个比特联合编码的形式可以是协议约定的形式或者是网络侧和终端侧默认的形式。
示例性地，该一个比特为“1”时，指示网络设备使用资源分配位图在对应的频域资源组1中分配频域资源，该一个比特为“0”时，指示网络设备使用资源分配位图在对应的频域资源组2中分配频域资源。或者该一个比特为“1”时，指示网络设备使用资源分配位图在对应的频域资源组2中分配频域资源，该一个比特为“0”时，指示网络设备使用资源分配位图在对应的频域资源组1中分配频域资源。
也就是，在第一信息中可以额外用多个比指示一个或多个资源分配位图与网络设备的对应关系，比如，该多个比特为“00”时，指示网络设备使用资源分配位图在对应的频域资源组1中分配频域资源，该一个比特为“01”时，指示网络设备使用资源分配位图在对应的频域资源组2中分配频域资源。该多个比特为“11”时，指示网络设备使用资源分配位图分别在对应的频域资源组1和频域资源组2中分配频域资源。
其中，资源分配位图的所有信息位均有效，或者，所述资源分配位图中包括至少一个无效的信息位，比如资源分配位图中的最后一个或多个信息位无效，有效是指信息位对应的频域资源有效，无效是指没有与信息位对应的频域资源。
在另一些实施方式中，所述第一信息包括：资源指示值(Resource Indication Value，RIV)指示域，资源指示值指示域包括：至少一个RIV，所述RIV用于指示：在一个或多个频域资源组中为所述终端分配的频域资源。
其中，资源指示值指示域的大小与
Figure PCTCN2021084490-appb-000006
相关，若
Figure PCTCN2021084490-appb-000007
值大，则资源指示值频域资源分配域大，若
Figure PCTCN2021084490-appb-000008
值小，则资源指示值频域资源分配域小。
可以理解的是，RIV可以指示所分配的起始PRB位置和连续分配的PRB个数。
在本发明实施例中，RIV、使用RIV分配频域资源的网络设备和频域资源组中的至少两项具有对应关系。
示例性地，频域资源组与使用RIV分配频域资源的网络设备具有对应关系。比如，多个网络设备同时调度同一个终端时，每个网络设备只通过对应的RIV指示在对应的频域资源组中分配频域资源。
可以理解的是，频域资源组与网络设备的对应关系可以由协议约定，或者由终端确定，或者由网络侧配置，比如，终端可以根据预设规则确定频域资源组与网络设备的对应关系，该预设规则设置为：第一个网络设备对应第一个频域资源组，第二个网络设备对应的频域资源组是第一个频域资源组加上一个偏移值。
或者，所述资源指示值与分配频域资源的网络设备的对应关系由协议约定，或者由所述终端根据预设规则确定，该预设规则设置为：第一个网络设备对应第一个RIV，第二个网络设备对应的RIV是第一个RIV加上一个偏移值
可选地，RIV、使用RIV分配频域资源的网络设备和频域资源组中至少两项的对应关系可以通过网络侧配置。
可选地，在第一信息中还包括：第一指示信息，该第一指示信息指示：(1)RIV与一个或多个网络设备的对应关系；(2)网络设备与一个或多个频域资源组(sub-BWP)的对应关系；(3)RIV与一个或多个频域资源组(sub-BWP)的对应关系。
可选地，第一指示信息包括：一个信息位或多个信息位。
比如，该第一指示信息包括：1比特信息，该比特为“0”表示网络设备1使用第一频域资源组(第一sub-BWP)分配频域资源，该比特为“1”表示网络设备2使用第二频域资源组(第一sub-BWP)分配频域资源；或者，该比特为“1”表示网络设备1使用第一个频域资源组(第一sub-BWP)分配频域资源，该比特为“0”表示网络设备2使用第二频域资源组(第二sub-BWP)分配频域资源；
又比如，该第一指示信息还包括：1比特信息，该比特为“0”表示网络设备1使用第一频域资源组(第一sub-BWP)或第二个频域资源组(第二sub-BWP)分配频域资源，该比特为“1”表示网络设备1使用第一频域资源组(第一sub-BWP)和第二频域资源组(第二sub-BWP)分配频域资源，即使用两 个频域资源组分配频域资源。
比如，用多个比特联合编码指示：网络设备与频域资源组(sub-BWP)的对应关系。
示例性地，两个比特联合编码指示的方式如下：
(1)两个比特(0,0)表示网络设备使用第一sub-BWP分配频域资源；
(2)两个比特(0,1)表示网络设备使用第二sub-BWP分配频域资源；
(3)两个比特(1,1)表示网络设备使用第一sub-BWP和第二sub-BWP分配频域资源；
(4)两个比特(1,0)待定表示的含义不进行限定。
可以理解的是，上述一个比特或者多个比特联合编码的形式可以是协议约定的形式或者是网络侧和终端侧默认的形式。
在本发明实施例中，可以减少网络侧下发指示频域资源分配的控制信息的开销。
参见图3，本发明实施例还提供一种频域资源指示的方法，该方法的执行主体为网络设备，包括：步骤301。
步骤301：发送第一信息，所述第一信息用于指示在M个频域资源组中的至少一个频域资源组为所述终端分配的频域资源；
其中，所述M个频域资源组中包括N个频域资源，所述N和M均为大于或等于2的正整数。
在本发明实施例中，在单个传输点(single TRP)传输情况下的频域资源分配方式中，由于单个传输点下发的第一信息可以指示在一个或多个频域资源组中为终端分配的频域资源，而不需要指示所有频域资源中的每个频域资源是否分配给该终端，这样可以减少第一信息中的信息位的数量，节省网络侧下发控制信息的开销。而在多个传输点(multi TRP)传输情况下的频域资源分配方式中，由于第一信息可以指示多个传输点在一个或多个频域资源组中为终端分配的频域资源，而不用每个传输点均下发控制信息指示频域资源分配的情况，这样可以减少网络侧下发控制信息的开销。。

可以理解的是，如果DCI中只包括额外的1比特，该1比特可以实现上述第一比特或第二比特的作用。
