在本公开中使用的术语“网络设备”是可以用于与终端设备通信的实体或节点，例如可以是接入网设备。接入网设备可以是部署在无线接入网中为移动终端提供无线通信功能的装 置，例如可以是无线接入网(Radio Access Network，RAN)网络设备。接入网设备可以包括各种类型的基站。作为示例，接入网设备可以包括各种形式的宏基站、微基站、微微基站、毫微微基站、中继站、接入点、远程无线电单元(Remote Radio Unit，RRU)、射频头(Radio Head，RH)、远程无线电头端(Remote Radio Head，RRH)等等。在采用不同的无线接入技术的***中，接入网设备的名称可能会有所不同，例如在长期演进***(Long Term Evolution，LTE)网络中称为演进的节点B(evolved NodeB，eNB或eNodeB)，在3G网络中称为节点B(NodeB，NB)，在5G网络中可以称为g节点B(gNB)或NR节点B(NR NB)，等等。在某些场景下，接入网设备可以包含集中单元(Central Unit，CU)和/或分布单元(Distributed Unit，DU)。CU和DU可以放置在不同的地方，例如：DU拉远，放置于高话务量的区域，CU放置于中心机房。或者，CU和DU也可以放置在同一机房。CU和DU也可以为一个机架下的不同部件。为方便描述，本公开后续的实施例中，上述为移动终端提供无线通信功能的装置统称为网络设备，本公开的实施例不再具体限定。
无线网络移动运营商的频谱资源是有限的，各个标准所能够支持的小区带宽也是固定的。在一些场景下，运营商的频谱不是标准所支持的最大带宽的整数倍。例如，运营商分配到的带宽频谱是160MHz，同一覆盖区域可以组成100MHz+60MHz的组网。
为了实现性能提升，一种方案如图1所示。图1示出了运营商对两个小区频谱分配的场景100的一个示意图，其中，小区1和小区2可以组成100MHz+100MHz的组网形式，中间重叠段的40MHz是由小区1和小区2共享的。
但是，在同一个时间段(如一个时隙)内，被共享的40MHz在频谱上会被拆分为不重叠的两段，其中一段由小区1使用，另一段由小区2使用。这种共享方式也可以被称为时分复用频谱。例如如图2示出的是一种共享方案200。如图2所示，在T1时间，由小区1使用中间的40MHz，即小区1可使用的频谱范围是100MHz，而小区2可使用的频谱范围是60MHz。在T2时间，由小区2使用中间的40MHz，即小区1可使用的频谱范围是60MHz，而小区2可使用的频谱范围是100MHz。图2中所示的时分复用的方案能够在一定程度上实现动态频谱共享。
图3示出了本公开实施例可实现在其中的通信***300的一个示意图。如图3所示，该***300包括网络设备310、调度模块320、终端设备330-1至330-3(统称为终端设备330)、以及终端设备340-1至340-4(统称为终端设备340)。网络设备310可以与终端设备330、终端设备340进行通信。
调度模块320可以独立于网络设备310或者可以被集成在网络设备310内。在调度模块320独立于网络设备310的场景中，调度模块320所在的设备可以是另一接入网设备，调度模块320与网络设备310之间可以进行通信。在调度模块320被集成在网络设备310内的场景中，调度模块320可以作为网络设备310的内部模块。
为了简洁，图3中将调度模块320示出为独立于网络设备310，但是应理解，本公开不限于此。另外应注意的是，下文中的一些实施例描述了调度模块320与网络设备310之间的通信，这些通信在调度模块320被集成在网络设备310内的场景中可以被理解为是网络设备310的内部操作。
下面将结合图3描述本公开的实施例中的资源分配的方案。
图4示出了根据本公开的实施例的资源分配的过程400的示意流程图。过程400可以由如图3所示的调度模块320执行。可理解，调度模块320可以独立于网络设备310，被实现 为物理上独立的网元。或者，调度模块320可以被集成在网络设备310内部，被实现为网络设备310的一部分，在这种情形下，也可以认为过程400由网络设备310执行。
在框410，确定第一组终端设备的第一空间相关信息和第二组终端设备的第二空间相关信息。
在框420，基于第一空间相关信息和第二空间相关信息，确定针对第一组终端设备的第一传输资源和针对第二组终端设备的第二传输资源，第一传输资源和第二传输资源在频域上至少部分重叠。
如此，本公开的实施例提供了一种资源分配的方案，使得重叠段的频谱资源可以同时被不同的小区使用。与如图2所示的时分复用的方案相比，本公开的实施例以空分复用的方式提升了资源的利用率。
结合图3，可以假设第一组终端设备包括终端设备330-1至330-3，为了简洁，将第一组终端设备统称为终端设备330。可以假设第二组终端设备包括终端设备340-1至340-4，为了简洁，将第二组终端设备统称为终端设备340。应注意，本公开的实施例对第一组终端设备中所包括的终端设备的数量不做限定，例如可以为1个、2个或更多个，第一组终端设备也可以被称为第一终端设备簇或者第一终端设备集合或者其他名称等。类似地，本公开的实施例对第二组终端设备中所包括的终端设备的数量不做限定，例如可以为1个、2个或更多个，第二组终端设备也可以被称为第二终端设备簇或者第二终端设备集合或者其他名称等。本公开对此不限定。
第一组终端设备所在的小区可以为第一小区，第二组终端设备所在的小区可以为第二小区，并且第一小区和第二小区为不同的小区。
在一些实施例中，第一组终端设备中的任意两个终端设备之间的距离都小于第一距离阈值，或者，第一组终端设备中的所有终端设备使用相同的波束(例如第一波束)与网络设备310进行通信。类似的。第二组终端设备中的任意两个终端设备之间的距离都小于第二距离阈值，或者，第二组终端设备中的所有终端设备使用相同的波束(例如第二波束)与网络设备310进行通信。示例性地，第一距离阈值可以是基于第一小区的大小所确定的，第二距离阈值可以是基于第二小区的大小所确定的，第一距离阈值和第二距离阈值可以相等也可以不相等。示例性地，第一波束和第二波束为不同的波束。
第一组终端设备中的任一终端设备(例如第一终端设备)与第二组终端设备中任一终端设备(例如第二终端设备)之间的距离大于第三距离阈值，第三距离阈值大于第一距离阈值，且第三距离阈值大于第二距离阈值。
可选地，第一组终端设备与第二组终端设备可以使用相同的制式，例如都是NR终端。可选地，第一组终端设备与第二组终端设备可以使用不同的制式，例如第一组终端设备是长期演进(Long Term Evolution，LTE)终端，第二组终端设备是NR终端。
在一些实施例中，第一空间相关信息可以是基于来自第一组终端设备中至少一个终端设备的测量报告所确定的。在一些实施例中，第一空间相关信息可以是基于来自第一组终端设备中至少一个终端设备的位置信息所确定的。
举例而言，第一组终端设备中至少一个终端设备可以周期性地将测量报告或者位置信息发送至网络设备。
举例而言，第一组终端设备中至少一个终端设备可以基于来自网络设备的请求而将测量报告或者位置信息发送至网络设备，如结合下面图5的实施例所描述的。
图5示出了根据本公开的实施例的确定第一组终端设备的第一空间相关信息的过程500的交互信令图。过程500涉及网络设备310、调度模块320和终端设备330。
在过程500中，网络设备310向终端设备330发送510请求消息。
在一些实施例中，该请求消息可以包括测量请求。具体的，该测量请求可以指示终端设备330进行信道探测参考信号(Sounding Reference Signal，SRS)测量或者预编码矩阵指示(Pre-coding Matrix Indication，PMI)测量等。
应注意，尽管此处列举出了进行测量可以基于SRS或者PMI，但是本公开的实施例对此不限定，实际场景中也可以基于其他的信号进行测量，其他信号例如可以是信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、同步信号块(Synchronization Signal Block，SSB)等，这里不再一一罗列。
在一些实施例中，该请求消息可以包括位置上报指示信息。具体的，该位置上报指示信息可以指示终端设备330上报位置信息。
可理解，请求消息可以是网络设备310通过广播的方式发送的。或者，请求消息也可以是网络设备310通过单播或组播的方式发送的，本公开对此不限定。
随后，终端设备330基于请求消息确定520针对该请求消息的响应消息。
在请求消息包括测量请求的实施例中，终端设备330可以基于该测量请求进行空口测量，以得到测量报告。终端设备330可以通过波束扫描、信号强度测量等方式得到测量报告，但是可理解本公开的实施例不限于此。所得到的测量报告可以包括以下至少一项：SRS测量报告、PMI测量报告、CSI-RS测量报告、或SSB测量报告。应理解，测量报告也可以基于其他的信号进行测量得到，本公开中不再一一罗列。
测量报告可以是终端设备330基于一次测量得到的测量结果生成的，也可以是基于多个测量得到的多个测量结果生成的。
在请求消息包括位置上报指示信息的实施例中，终端设备330可以基于该位置上报指示信息确定位置信息。例如，终端设备330可以通过其定位模块来确定位置信息，该位置信息可以包括经纬度信息和/或高度信息(如海拔)等。
本公开的实施例中，终端设备330可以采用目前已有的或者以后发展的定位技术来确定位置信息。例如可以采用观测到达时间差(Observed Time Difference of Arrival，OTDOA)技术等，这样对于在较长时间内位置固定且长期在线的终端设备而言可以更加准确地确定位置信息。
另外，应注意的是，确定响应消息的终端设备330可以是接收到请求消息的任一个终端设备330。换句话说，对于接收到请求消息的终端设备330而言，其可以确定响应消息，也可以忽略请求消息不确定对应的响应消息。结合图3，举例而言，终端设备330-1至终端设备330-3可以都接收到请求消息，但是只有终端设备330-1基于请求消息确定响应消息，而终端设备330-2和终端设备330-3忽略该请求消息没有生成对应的响应消息。也就是说，所有终端设备330中，只要有其中的至少一个基于请求消息确定响应消息即可。
随后，终端设备330将响应消息发送530到网络设备310。
在一些实施例中，如图5中的虚线框540所示，网络设备310可以基于响应消息确定542终端设备330的第一空间相关信息。随后，网络设备310可以将第一空间相关信息发送544到调度模块320。
在一些实施例中，如图5中的虚线框550所示，网络设备310可以将响应消息发送552 到调度模块320。随后调度模块320可以基于该响应消息确定554终端设备330的第一空间相关信息。
可理解，540和550是择一执行的。可理解，对于调度模块320被集成在网络设备310内部的场景而言，图5中所示出的544和552相应地应理解为是网络设备310的内部操作。
网络设备310或者调度模块320基于响应消息确定第一空间相关信息可以包括：网络设备310或者调度模块320基于测量报告或位置信息来确定第一空间相关信息。在一些实施例中，第一空间相关信息可以包括第一组终端设备相对于网络设备310的第一水平方位和/或第一组终端设备与网络设备310之间的第一距离。
在一些实施例中，网络设备310可以接收来自多个终端设备330的多个响应消息，相应地，网络设备310或者调度模块320基于多个响应消息确定第一空间相关信息。
第一水平方位可以表示为角度的形式。例如，可以确定响应消息所来自的终端设备330(一个或多个)的中心和网络设备310之间的连线与预定方向之间的夹角，其中预定方向可以为与纬度平行的方向、或者与经度平行的方向等。
第一距离可以表示为响应消息所来自的终端设备330(一个或多个)的中心和网络设备310之间的直线距离。或者，第一距离可以表示为响应消息所来自的多个终端设备330与网络设备310之间的多个距离的均值。
应注意的是，本公开实施例中的第一空间相关信息可以包括其他的信息，例如天线端口、波束标识、或所在扇区标识等，本公开的实施例对此不限定。
另外，可理解，图5所示的确定第一组终端设备的第一空间相关信息的实施例仅是示意，在一些实施例中，第一组终端设备中至少一个终端设备可以周期性地将测量报告或者位置信息发送至网络设备310。随后，类似于图5中的虚线框540所示，网络设备310可以基于测量报告或者位置信息确定终端设备330的第一空间相关信息，并且可以将第一空间相关信息发送到调度模块320。或者随后，类似于图5中的虚线框550所示，网络设备310可以将测量报告或者位置信息发送到调度模块320，并由调度模块320确定终端设备330的第一空间相关信息。
以上结合图5描述了确定第一组终端设备的第一空间相关信息的实施例，可理解的是，本公开中确定第二组终端设备的第二空间相关信息的方式是类似的，为了简洁，这里不再赘述。
应注意，本公开的实施例中确定第一组终端设备的第一空间相关信息以及确定第二组终端设备的第二空间相关信息是彼此独立的。举例而言，可以并行地或者不同时地确定第一空间相关信息和第二空间相关信息。举例而言，可以采用相同的方式或不同的方式来确定第一空间相关信息和第二空间相关信息。例如，通过第一组终端设备的测量报告来确定第一空间相关信息，通过第二组终端设备的位置信息来确定第二空间相关信息；等等。
类似地，可以理解，第二空间相关信息可以包括第二组终端设备相对于网络设备310的第二水平方位和/或第二组终端设备与网络设备310之间的第二距离。第二水平方位可以表示为，例如，第二组终端设备的中心和网络设备310之间的连线与预定方向之间的夹角，其中预定方向可以为与纬度平行的方向、或者与经度平行的方向等。第二距离可以表示为，例如，第二组终端设备的中心和网络设备310之间的直线距离。另外，第二空间相关信息可以包括其他的信息，例如天线端口、波束标识、或所在扇区标识等，本公开的实施例对此不限定。
进一步地，调度模块320可以基于第一空间相关信息和第二空间相关信息两者，来确定 针对第一组终端设备的第一传输资源和针对第二组终端设备的第二传输资源。
图6示出了根据本公开的实施例的确定第一传输资源和第二传输资源的过程600的示意流程图。过程600由调度模块320执行，可理解，对于调度模块320被集成在网络设备310中的场景，过程600也可以由网络设备310来执行。
在框610，确定第一空间相关信息和第二空间相关信息之间的空间关联度。
结合如上图5所示的实施例，第一空间相关信息可以包括第一组终端设备相对于网络设备310的第一水平方位和/或第一组终端设备与网络设备310之间的第一距离，第二空间相关信息可以包括第二组终端设备相对于网络设备310的第二水平方位和/或第二组终端设备与网络设备310之间的第二距离。在一些实施例中，可以基于以下至少一项来确定空间关联度：第一水平方位与第二水平方位之间的夹角，或，第一距离与第二距离之间的差值。夹角可以理解为是绝对值夹角，差值可以理解为是绝对值差值。
本公开的实施例对空间关联度的具体形式不作限定。例如，空间关联度可以被表示为180度与绝对值夹角的差值。例如，空间关联度可以被表示为绝对值差值的倒数。例如，空间关联度可以被表示为(a)180度与绝对值夹角的差值与(b)绝对值差值的倒数的加权和。例如，空间关联度可以被构建为绝对值夹角和/或绝对值差值的函数，且其取值范围为0至1。
空间关联度可以相反地用于表征第一组终端设备与第二组终端设备之间的空间隔离度。例如，绝对值夹角越接近于180度，说明该空间隔离度高。例如，绝对值差值越大，说明该空间隔离度越高。
在框620，确定空间关联度是否低于阈值关联度。
可理解，阈值关联度的形式取决于空间关联度的具体形式。作为一例，空间关联度被表示为180度与绝对值夹角的差值，相应地，阈值关联度为角度阈值，例如30度或其他值。作为一例，空间关联度被表示为绝对值差值的倒数，相应地，阈值关联度为数值阈值，例如0.1或其他值。作为一例，空间关联度被表示为0至1之间的归一化值，相应地，阈值关联度为数值阈值，例如0.3或其他值。
如果在框620处确定空间关联度不低于阈值关联度，则前进到框630；相反，如果在框620处确定空间关联度低于阈值关联度，则前进到框640。
在框630，确定针对第一组终端设备的第一传输资源和针对第二组终端设备的第二传输资源，并且所确定的第一传输资源和第二传输资源在频域上完全不重叠。
如果确定空间关联度不低于阈值关联度，即第一组终端设备与第二组终端设备之间的隔离度低，此时这两组终端设备之间在相同的频域可能会存在干扰，因此可以使第一传输资源和第二传输资源不重叠。例如，第一传输资源在频域上的范围为f11至f12，第二传输资源在频域上的范围为f13至f14，且f11<f12<f13<f14。
在框640，确定针对第一组终端设备的第一传输资源和针对第二组终端设备的第二传输资源，并且所确定的第一传输资源和第二传输资源在频域上至少部分重叠。
如果确定空间关联度低于阈值关联度，即第一组终端设备与第二组终端设备之间的隔离度高，此时这两组终端设备之间在相同的频域不会产生干扰，因此可以使第一传输资源和第二传输资源至少部分重叠，例如完全重叠或部分重叠。
作为另一种表述，可以将能够使用部分重叠的频域传输资源的两组不同的终端设备称为能够配对的终端设备。可理解，配对的终端设备能够被并行地分别调度频域资源。这样，能够实现空分复用，提升频谱资源的利用率。
举例而言，第一传输资源在频域上的范围为f21至f22，第二传输资源在频域上的范围为f23至f24，且f21<f23<f22<f24。也就是说，在f23至f22的频域范围内两个传输资源是重叠的。在该示例中，重叠的部分(即f23至f22)属于第一传输资源所指示的第一频域范围的高频部分，同时属于第二传输资源所指示的第二频域范围的低频部分。
对于第一传输资源和第二传输资源在频域上部分重叠的情形，在一些实施例中，重叠的部分占第一频域范围的比例可以低于第一阈值，例如，该第一阈值可以为40％或其他值。重叠的部分占第二频域范围的比例可以低于第二阈值，例如该第二阈值可以为40％或其他值。可理解，第一阈值和第二阈值可以相等或不相等，本公开对此不限定。
如此，通过本公开的实施例，在第一空间相关信息与第二空间相关信息之间的空间关联度低于阈值关联度的情况下，可以确定针对第一组终端设备的第一传输资源与针对第二组终端设备的第二传输资源在频域上部分重叠，即使第一组终端设备中的一个或多个第一终端设备与第二组终端设备中的一个或多个第二终端设备同时在相同的频域进行上下行传输，也不会互相干扰，从而在保证传输效率的同时提升了资源的利用率。
本公开的实施例中，第一组终端设备所在的小区可以为第一小区，第二组终端设备所在的小区可以为第二小区，相应地，所确定的第一传输资源为第一小区可以使用的资源，所确定的第二传输资源为第二小区可以使用的资源。
进一步地，网络设备310或者调度模块320还可以进一步地为第一小区或第二小区中的终端设备进行资源调度。
以第一小区中的第一终端设备(假设为图3中的终端设备330-1)为例，终端设备330-1可以向网络设备310发送调度请求。随后网络设备310可以确定该终端设备330-1可以使用的资源，并且网络设备310可以向终端设备330-1发送调度许可，以指示该终端设备330-1可以使用的资源。可理解的是，该终端设备330-1可以使用的资源是第一传输资源的子集。
可理解，对于第一小区中的第一终端设备和第二小区中的第二终端设备，分别进行资源调度的过程是并行进行的，如此，即使在同一个时间段(如一个符号或一个时隙)，为第一终端设备所调度的资源和为第二终端设备所调度的资源在频域上可以重叠。这样，能够提升频域资源的利用率，进而能够提升整个网络的吞吐率。
图7示出了根据本公开的实施例的资源分配装置700的示意框图。装置700可以被实现为如图3中所示的调度模块320，或者可以被实现在如图3中所示的调度模块320中。
装置700可以包括第一确定单元710和第二确定单元720。第一确定单元710可以被配置为确定第一组终端设备的第一空间相关信息和第二组终端设备的第二空间相关信息。第二确定单元720可以被配置为基于第一空间相关信息和第二空间相关信息，确定针对第一组终端设备的第一传输资源和针对第二组终端设备的第二传输资源，第一传输资源和第二传输资源在频域上至少部分重叠。
具体地，第二确定单元720可以被配置为：确定第一空间相关信息和第二空间相关信息之间的空间关联度；以及如果空间关联度低于阈值关联度，确定针对第一组终端设备的第一传输资源和针对第二组终端设备的第二传输资源，第一传输资源和第二传输资源在频域上至少部分重叠。
可理解，第一传输资源和第二传输资源在频域上可以完全重叠或者可以部分重叠。
对于第一传输资源和第二传输资源在频域上部分重叠的情形，第一传输资源所指示的第一频域范围的低频部分与第二传输资源所指示的第二频域范围的高频部分重叠。并且，在一 些实施例中，低频部分在第一频域范围中的比例不超过第一阈值，和/或，高频部分在第二频域范围中的比例不超过第二阈值。举例而言，第一阈值和第二阈值可以相等，例如都为40％。
可选地，在一些实施例中，第一确定单元710可以被配置为：接收来自第一组终端设备中的至少一个第一终端设备的第一测量报告，第一测量报告包括与至少一个终端设备有关的信道探测参考信号测量结果或者预编码矩阵指示测量结果；以及基于至少一个第一终端设备的第一测量报告确定第一空间相关信息。或者可选地，在一些实施例中，第一确定单元710可以被配置为：接收来自第一组终端设备中的至少一个第一终端设备的第一位置信息；以及基于至少一个第一终端设备的第一位置信息确定第一空间相关信息。
类似地，在一些实施例中，第一确定单元710可以被配置为：接收来自第二组终端设备中的至少一个第二终端设备的第二测量报告，第二测量报告包括与至少一个第二终端设备有关的信道探测参考信号测量结果或者预编码矩阵指示测量结果；以及基于至少一个第二终端设备的第二测量报告确定第二空间相关信息。或者可选地，在一些实施例中，第一确定单元710可以被配置为：接收来自第一组第二终端设备中的至少一个第二终端设备的第二位置信息；以及基于至少一个第二终端设备的第二位置信息确定第二空间相关信息。
在一些实施例中，第一空间相关信息可以包括以下至少一项：第一组终端设备相对于网络设备的第一水平方位、第一组终端设备与网络设备之间的第一距离。并且第二空间相关信息可以包括以下至少一项：第二组终端设备相对于网络设备的第二水平方位、第二组终端设备与网络设备之间的第二距离。相应地，第一空间相关信息和第二空间相关信息之间的空间关联度可以由第二确定单元720基于以下至少一项被确定：第一水平方位与第二水平方位之间的夹角，或第一距离与第二距离之间的差值。
示例性地，图7中的装置700可以被实现为调度模块320，或者可以被实现为调度模块320中的芯片或芯片***。可理解，对于调度模块320被集成在网络设备310中的场景而言，图7中的装置700可以被实现为网络设备310，或者可以被实现为网络设备310中的芯片或芯片***，本公开的实施例对此不限定。
本公开的实施例中对模块或单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时也可以有另外的划分方式，另外，在公开的实施例中的各功能单元可以集成在一个单元中，也可以是单独物理存在，也可以两个或两个以上单元集成为一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
图7中的装置700能够用于实现上述结合图4至图6中由调度模块320所述的各个过程，为了简洁，这里不再赘述。
图8示出了可以用来实施本公开的实施例的示例设备800的示意性框图。设备800可以被实现为或者被包括在图3的调度模块320中。如图所示，设备800包括一个或多个处理器810，耦合到处理器810的一个或多个存储器820，以及耦合到处理器810的通信模块840。

存储器820可以包括一个或多个非易失性存储器和一个或多个易失性存储器。非易失性 存储器的示例包括但不限于以下至少一种：只读存储器(Read-Only Memory，ROM)824、可擦除可编程只读存储器(Erasable Programmable Read Only Memory，EPROM)、闪存、硬盘、光盘(Compact Disc，CD)、数字视频盘(Digital Versatile Disc，DVD)或其他磁存储和/或光存储。易失性存储器的示例包括但不限于以下至少一种：随机存取存储器(Random Access Memory，RAM)822、或不会在断电持续时间中持续的其他易失性存储器。
