相关申请的交叉引用
本申请主张在2020年1月23日在中国提交的中国专利申请号No.202010076449.1的优先权,其全部内容通过引用包含于此。
技术领域
本发明涉及通信技术领域,尤其涉及一种频域资源处理方法、频域资源配置方法及相关设备。
背景技术
自接入回传(Integrated Access Backhaul,IAB)系统是新空口(New Radio,NR)第十六版本(Release 16,Rel-16)开始制定标准的一项技术。如图1所示的IAB系统的结构示意图,一个IAB节点包括分布单元(Distributed Unit,DU)功能部分和移动设备(Mobile Termination,MT)功能部分。依靠MT,一个接入IAB节点(即IAB node)可以找到一个上游IAB节点(即parent IAB node),并跟接入IAB节点的DU建立无线连接,该无线连接被称为回传链接(即backhaul link)。在一个IAB节点建立完整的回传链路后,该IAB节点打开其DU功能,DU会提供小区服务,即DU可以为UE提供接入服务。一个自接入回传回路还包含一个宿主IAB节点(即donor IAB node),宿主IAB节点有直接相连的有线传输网。
图2是一种IAB系统的中心单元-分布单元(Centralized Unit-Distributed Unit,CU-DU)的结构示意图。在一个自接入回传回路中,所有的IAB节点的DU都连接到一个CU节点,该CU节点包括CU控制面(即CU-CP)和CU用户面(即CU-UP),由CU节点通过F1-AP(即F1应用协议)协议对DU进行配置,通过无线资源控制(Radio Resource Control,RRC)协议对MT进行配置。宿主IAB节点没有MT功能部分。IAB系统的引入是为了针对接入点密集部署时,有线传输网部署不到位的情况,即在没有有线传输网络时,接入点可以依赖无线回传。
然而,现有技术中DU和MT的收发采用的是时分复用(Time Division Multiplexing,TDM)的方式,这种复用方式会导致IAB节点转发信息的时延较大。为了降低IAB节点转发信息的时延,DU和MT可以采用空分复用(Space Division Multiplexing,SDM)或频分复用(Frequency-division multiplexing,FDM)的复用方式,然而,在DU和MT利用SDM或FDM的复用方式进行信息收发的情况下,如何利用频域资源进行信息收发并没有相关的解决方案。
发明内容
本发明实施例提供一种频域资源处理方法、频域资源配置方法及相关设备,以提供一种在DU和MT利用SDM或FDM的复用方式的情况下频域资源的利用方式,以减少DU和MT之间收发的干扰或实现DU和MT之间收发的干扰可知。

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“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例,例如除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,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、系统、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和/或C,表示包含单独A,单独B,单独C,以及A和B都存在,B和C都存在,A和C都存在,以及A、B和C都存在的7种情况。
为便于理解本发明实施例,首先对本发明实施例中所涉及到的一些相关概念进行说明。
空分复用(Space Division Multiplexing,SDM)/频分复用(Frequency-division multiplexing,FDM)的复用方式:
接入链路(即access link)和回传链路(即backhaul link)的复用方式可以是SDM或FDM。采用FDM的复用方式,分布单元(Distributed Unit,DU)和移动设备(Mobile Termination,MT)可以同时在不同的频域资源上进行收发(即同收或同发或一收一发)。采用SDM的复用方式,DU和MT可以同时在相同的频域资源上进行收发(即同收或同发或一收一发)。
此时,DU和MT的一个进行信号接收的时候会受到另一个的干扰,例如:DU接收信号的时候,受到MT发送或接收信号的干扰;反之,MT接收信号的时候,受到DU发送或接收信号的干扰。
DU和MT的双工(即duplexing)方式:
IAB节点的DU和MT之间双工方式分为半双工(即Half duplex)和全双工(Full duplex)的方式。
在半双工的情况下,DU和MT中一方在发送的时候,另一方不能接收(反之亦然)。因此,其在FDM或者SDM的复用方式下,DU和MT的收发操作方式可以有以下几种:
DU-TX&MT-TX,即DU配置为下行链路(Down Link,DL),MT配置为上行链路(Up Link,UL);
DU-RX&MT-RX,即DU配置为UL,MT配置为DL。
在全双工的情况下,DU和MT可以同时收发。因此,其在FDM或者SDM的复用方式下,DU和MT的收发操作方式可以有以下几种:
DU-TX&MT-TX,即DU配置为DL,MT配置为UL;
DU-RX&MT-RX,即DU配置为UL,MT配置为DL;
DU-TX&MT-RX,即DU配置为DL,MT配置为DL;
DU-RX&MT-TX,即DU配置为UL,MT配置为UL。
另外,在全双工的情况下,DU-TX&MT-RX或者DU-RX&MT-TX更适合的场景是DU和MT采用不同的射频(Radio Frequency,RF)/面板(即panel)。需要说明的是,本发明实施例中DU和MT也可以采用不相同的RF/panel。
参见图3,图3是本发明实施例可应用的一种网络系统的结构图,如图3所示,包括IAB节点11、第一设备12和第四设备13,其中,IAB节点11包括分布单元(Distributed Unit,DU)和移动设备(Mobile Termination,MT)。第一设备12可以是中心单元(Centralized Unit,CU)或IAB节点11的父节点(即parent IAB node,也可以称为上游IAB节点)。第四设备13可以是IAB节点11调度的用户设备(User Equipment,UE)或IAB节点11的子IAB节点(即Child IAB node,也可以称为下游IAB节点)的MT。
需要说明的是,本发明实施例提供的一种频域资源处理方法可以由上述IAB节点11执行;本发明实施例提供的频域资源配置方法可以由上述第一设备12执行,本发明实施例提供的另一种频域资源处理方法可以由上述第四设备13执行,详细内容请参见下述说明。
本发明实施例提供一种频域资源处理方法,应用于IAB节点。参见图4,图4是本发明实施例提供的频域资源处理方法的流程图,如图4所示,包括以下步骤:
步骤401、获取频域配置信息,其中,所述频域配置信息包括保护频带的配置信息和IAB节点的DU的频域资源的配置信息中的至少一项。
本实施例中,上述保护频带(即Guard band)的配置信息可以包括DU和MT中的至少一项的保护频带的配置信息,也即保护频段可以配置于DU和MT中的至少一项。
可选的,可以协议预定义IAB节点的频域配置信息;也可以由CU或是IAB节点的父节点等配置IAB节点的频域配置信息;也可以在协议预定义IAB节点的频域配置信息之外,还由CU或是IAB节点的父节点等配置IAB节点的频域配置信息。
可选的,上述频域配置信息可以是显示配置的,例如,可以通过RRC、F1-C、下行控制信息(Downlink Control Information,DCI)或媒体接入控制(Media Access Control,MAC)控制单元(Control Element,CE)等信令传输上述频域配置信息给IAB节点;也可以是隐式配置的,例如,规定IAB节点的DU的频域资源和该IAB节点的父节点的DU的频域资源的重叠部分为IAB节点的DU的分享资源类型的频域资源,或者规定DU的硬资源类型或软资源类型的频域资源的上边界处的频域资源为保护频带等。
需要说明的是,上述频域配置信息还可以包括MT的频域资源的配置信息,本实施例对此不做限定。
步骤402、根据所述频域配置信息进行信息传输。
本实施例中,通过配置DU的频域资源和保护频段中的至少一项,并根据配置的DU的频域资源和保护频段中的至少一项进行信息传输,可以实现DU和MT之间干扰的减少或者实现DU和MT之间的干扰可知,以保证传输的服务质量(Quality of Service,QoS)。
可选的,上述步骤401,也即所述获取频域配置信息,可以包括以下至少一项:
从第一设备接收频域配置信息;
获取协议预定义的频域配置信息。
本实施例中,上述第一设备可以是CU或是上述IAB节点的父节点。
在一实施方式中,IAB节点可以从第一设备接收频域配置信息,也即通 过第一设备配置频域,可以提高频域配置的灵活性。
在另一实施方式中,IAB节点可以获取协议预定义的频域配置信息,也即通过协议预定义频域配置,可以节省信令,进而节省系统资源。
在另一实施方式中,IAB节点可以在从第一设备获取到频域配置信息之前,获取协议预定义的频域配置信息,并基于协议预定于的频域配置信息进行信息传输,在从第一设备获取到频域配置信息之后,基于从第一设备获取的频域配置信息进行信息传输,这样可以提高数据传输的可靠性,保证传输的QoS。
可选的,所述DU的频域资源的配置信息包括所述DU的频域资源的资源类型。
本实施例中,上述DU的频域资源可以配置为至少一种资源类型。例如,上述DU的频域资源可以配置为硬资源类型(即Hard类型)、软资源类型(即Soft类型)、不可用资源类型(即NA类型)和分享资源类型(即Shared类型)等中的一种或多种。例如,如图5所示,DU配置有Hard类型的频域资源、Soft类型的频域资源、Shared类型的频域资源和NA类型的频域资源。
可选的,所述DU的频域资源的资源类型可以包括如下至少一项:硬资源类型,软资源类型,不可用资源类型,分享资源类型。
其中,上述硬资源类型的频域资源仅可被DU使用;上述软资源类型的频域资源仅在不影响MT收发或者被指示为可用时可被DU使用;上述不可用资源类型资源的频域资源不可被DU使用;上述分享资源类型的频域资源可被DU和MT同时使用。
需要说明的是,本实施例可以采用显示的方式为DU配置上述一种或多种资源类型的频域资源,也可以采用隐式的方式为DU配置上述一种或多种资源类型的频域资源,对此不做限定。
本实施例中,上述DU的频域资源可以配置为硬资源类型、软资源类型、不可用资源类型和分享资源类型中的一种或多种,可以提高资源配置的灵活性,进而可以减少DU和MT之间收发的干扰。
可选的,所述方法还可以包括:
从第一设备接收第一指示信息;
其中,所述第一指示信息用于指示将所述DU的频域资源中软资源类型的频域资源作为第一类型的频域资源,所述第一类型包括如下至少一项:硬资源类型,不可用资源类型,分享资源类型;所述分享资源类型的频域资源可被所述DU和所述IAB节点的移动设备MT同时使用,也即DU和MT可以共同使用该频域资源进行收发。
其中,对于分享资源类型的频域资源,DU和MT的收发操作方式可以有以下至少一种:
DU-TX&MT-TX,也即DU发送,MT发送;
DU-RX&MT-RX,也即DU接收,MT发送;
DU-TX&MT-RX,也即DU发送,MT接收;
DU-RX&MT-TX,也即DU接收,MT接收。
本实施例中,上述第一设备可以是CU或是上述IAB节点的父节点。可选的,IAB节点可以通过DCI信令从第一设备接收第一指示信息。
例如,上述第一指示信息可以指示将配置给DU的频域资源中软资源类型的部分或全部频域资源作为硬资源类型的频域资源,或者指示将配置给DU的频域资源中软资源类型的部分或全部频域资源作为不可用资源类型的频域资源,或者指示将配置给DU的频域资源中软资源类型的部分或全部频域资源作为分享资源类型的频域资源,或者指示将配置给DU的频域资源中软资源类型的一部分频域资源作为硬资源类型的频域资源,另一部分作为分享资源类型的频域资源等。
本实施例通过第一指示信息指示将所述DU的频域资源中软资源类型的频域资源作为第一类型的频域资源,可以实现配置给DU的频域资源的资源类型的灵活切换。
可选的,所述DU的频域资源的配置信息包括所述DU的频域资源的资源位置。
在一实施方式中,可以采用比特图(即bitmap)的形式配置所述DU的频域资源的资源位置。例如,比特图中比特位的值为1指示相应的频域粒度配置为相应的资源类型,0反之,其开始位置可以为参考点A(即reference point A)、公共资源块0(即CRB0)、物理资源块0(即PRB0)或同步信号块 (Synchronous Signal Block,SSB)开始频点等。
在另一实施方式中,可以采用偏移(即offset)结合带宽的形式配置所述DU的频域资源的资源位置。例如,offset可以针对参考点A(即reference point A)、公共资源块0(即CRB0)、物理资源块0(即PRB0)或SSB开始频点等,带宽可以为相应的频域粒度的个数。
可选的,上述offset和带宽可以分别针对每种资源类型的频域资源单独配置;或者offset是针对DU的频域资源的统一配置,带宽可以针对每种资源类型的频域资源单独配置。例如,可以协议预定义每种资源类型的频域资源在连续的频域资源上,每种资源类型的顺序可以协议预定义或者配置,offset是针对DU的频域资源统一配置,带宽可以针对每种资源类型的频域资源单独配置。
可选的,所述DU的频域资源的配置粒度由协议预定义或者由第一设备配置。
本实施例中,上述配置粒度可以包括但不限于一个PBR、多个PRB、一个子载波(即sub-carrier)或多个子载波等。
需要说明的是,上述DU的频域资源中不同资源类型的频域资源的配置粒度可以相同,也可以不同。例如,上述DU的频域资源中不同资源类型的频域资源的配置粒度可以均为2个PRB,或者上述DU的频域资源中Hard类型的频域资源的配置粒度为1个PRB,上述DU的频域资源中Soft类型的频域资源的配置粒度为3个PRB等。
可选的,所述DU的频域资源中第二类型的频域资源为周期性的频域资源;
其中,所述第二类型包括如下至少一项:硬资源类型,软资源类型,不可用资源类型,分享资源类型。
本实施例中,可以配置DU的频域资源中一种或多种类型的频域资源为周期性的频域资源,也即周期性出现的频域资源。其中,上述频域资源的时间周期可以用时隙的序号、正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号的序号、时域offset或时长等表示。
例如,可以配置DU的频域资源中每种类型的频域资源均为周期性的频 域资源,或者可以配置DU的频域资源中部分类型的频域资源均为周期性的频域资源等。
可选的,所述DU的频域资源和第一频域资源之间的重叠资源的资源类型为分享资源类型;
其中,所述第一频域资源为所述IAB节点的父节点的DU的频域资源,所述分享资源类型的频域资源可被所述DU和所述IAB节点的移动设备MT同时使用。
本实施例中,可以隐式的配置DU的分享资源类型的频域资源。例如,在一个时隙(即Slot)或OFDM符号(即OFDM Symbol)内配置给IAB节点1的DU的频域资源(即频域配置1)和配置给其父IAB节(即IAB节点2)DU的频域资源(即频域配置2)存在重叠部分,则重叠部分为Shared类型的频域资源。
可选的,若CU将频域配置2通知给IAB节点1,将频域配置1通知给IAB节点2,那么两个IAB节点就可以判断两者的DU资源的重叠部分的大小。
本实施例通过隐式的配置DU的频域资源和第一频域资源之间的重叠资源的资源类型为分享资源类型,可以节省信令。
可选的,所述分享资源类型的频域资源不可被单独配置,仅可通过将软资源类型的频域资源动态指示为分享资源类型的频域资源。
可选的,所述DU的频域资源的配置信息包括所述DU的频域资源中至少一种类型的频域资源的最大发送功率。
本实施例中,可以为DU的频域资源中至少一种类型的频域资源配置最大发送功率。例如,可以为DU的频域资源中每种类型的频域资源均配置最大发送功率;也可以仅为DU的频域资源中部分类型的频域资源配置最大发送功率,如仅为DU的频域资源中Hard类型或Shared类型或Soft类型的频域资源配置最大发送功率。
可选的,所述最大发送功率可以根据所述IAB节点的最大输出功率确定,例如,最大发送功率可以是相对于述IAB节点的最大输出功率的一个比例或一个偏移(即Offset)等;也可以是配置的一个具体功率值。
本实施例通过配置DU的频域资源中至少一种类型的频域资源的最大发送功率,便于在根据DU的频域资源进行信息传输时进行功率控制。
可选的,所述DU的频域资源中承载于第一信令的频域资源的资源类型为硬资源类型;
其中,所述第一信令包括如下至少一项:SSB,物理下行控制信道(Physical Downlink Shared Channel,PDCCH),信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)。
本实施例中,可以由CU或IAB节点的父节点配置或协议预定义一些特殊信令传输的频域资源是DU的Hard类型的频域资源,这样可以节省用于DU的硬资源类型的频域资源配置的信令和资源。
可选的,所述方法还可以包括:
向第一设备发送期望的频域资源参数;
其中,所述频域资源参数包括如下至少一项:资源类型,带宽,频域位置。
本实施例中,IAB节点可以向第一设备上报其期望被配置的频域资源参数,从而第一设备可以根据其上报的频域资源参数为DU配置频域资源。其中,上述第一设备可以是CU或IAB节点的父节点。
本实施例中,IAB节点通过向第一设备发送期望的频域资源参数,以使第一设备可以根据其上报的频域资源参数为DU配置频域资源,可以提高DU的频域资源配置的准确性。
可选的,所述保护频带的配置信息包括如下至少一项:所述保护频带的带宽,所述保护频带的位置。

在一实施方式中,上述保护频带的位置可以是显示配置,例如,通过配置偏移(即Offset)的形式配置保护频带的位置,该offset可以针对参考点A、 CRB0、PRB0或SSB开始频点。
在另一实施方式中,上述保护频带的位置可以是隐式配置。例如,保护频带的位置可以根据第二设备的频域资源的位置确定,其中,所述第二设备为所述IAB节点中被配置所述保护频带的设备。
