具体实施方式
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。
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,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,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)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,尽管这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的示意图。无线通信系统包括终端11、IAB节点(IAB node)12、父IAB节点(parent IAB node)13和集中控制单元(Centralized Unit,CU)14。
在上述系统中IAB节点12可以依靠MT找到父IAB节点13,并跟父IAB节点13的DU建立无线连接,该无线连接被称为IAB节点12的回传链路(backhaul link),成为父IAB节点13的接入链路。在建立完整的回传链路后,IAB节点12打开其DU功能,DU会提供小区服务,即DU可以为终端11提供接入服务。所有的IAB节点的DU都可以与CU14连接。
另外,如图2所示,CU可以通过F1控制平面接口(F1-C)(F1应用流 程协议(F1-AP))协议进行对IAB节点的DU进行配置。CU可以通过无线资源控制(Radio Resource Control,RRC)协议对IAB节点的MT进行配置。且CU14可以是宿主节点(Donor IAB node)或者单独的网络节点,具体可以包括:CU-控制面(control plane,CP)和CU-用户面(user plane,UP)。
需要说明的是,图1仅是以终端11、IAB节点12、父IAB节点13和CU14进行举例说明,在实际应用中本申请实施例对IAB节点的数量不作限定。
另外,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)或车载终端(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)、低容量终端(Reduced Capacity User Equipment,RedCap UE)等终端侧设备,其中,RedCap UE可以包括:穿戴设备、工业传感器、视频监控设备等,穿戴设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。

上述可用频域资源包括所述MT的工作带宽可以是,DU的可用频域范围包括MT的工作带宽,上述可用频域资源位于所述MT的工作带宽内可以是DU的工作带宽/可用频域范围位于MT的工作带宽/可用频域范围内。
上述可用频域资源与所述MT的工作带宽存在资源重叠可以是:
DU的工作带宽/可用频域范围的低频/频域资源编号较低的资源与MT的工作带宽/频域范围的高频/频域资源编号较高的资源重叠;或者

例如:如图4所示,DU的可用频域范围包括MT的工作带宽。其中,保护间隔(guard band)可以在MT的工作带宽外,也可能在MT的工作带宽内。图4以保护间隔在MT工作带宽外为例。
又例如:如图5所示,DU的工作带宽/可用频域范围的低频/频域资源编号较低的资源与MT的工作带宽/频域范围的高频/频域资源编号较高的资源重叠。其中,保护间隔可以在MT的工作带宽外,也可以在MT的工作带宽内。图5以保护间隔在MT工作带宽外为例。

例如:当支持FDM的复用,则上述IAB节点不期望IAB DU的可用频域范围与IAB MT的工作带宽重叠;或者说,CU/父节点配置IAB DU的可用频域资源与IAB MT的工作带宽不重叠。具体可以是通过上述描述的显式或者隐式配置的方式实现FDM复用。
例如:当支持SDM的复用,上述IAB DU的可用频域范围可以与IAB MT的工作带宽有重叠。DU和MT在所述重叠的频域资源进行复用。另外,还可以采用额外的指示信令,指示DU是否可用重叠的部分,如果指示不可用,DU和MT切换回FDM资源复用,否则为SDM资源复用。或者,指示DU可以使用重叠资源中的部分资源。
在一种实施方式中,IAB节点可以上报IAB DU是否会使用IAB DU的 可用频域范围与IAB MT的工作带宽全部重叠的部分,或使用重叠资源中的部分资源,以便父节点或者CU判断重叠的部分是否真实存在SDM复用,以助于辅助父节点或者CU进行资源管理或者调度。
可选地,在所述IAB节点支持FDM的情况下,所述频域资源信息还用于指示所述可用频域资源可作为FDM复用资源。
该实施方式中,由于指示可用频域资源可作为FDM复用资源,这样可以实现在IAB DU的可用频域资源与IAB MT的工作带宽发生重叠之前,预先指示潜在的SDM复用,为带宽片段(Bandwidth part,BWP)的切换做准备,以提高切换效率。
可选地,在所述IAB节点支持SDM的情况下,所述频域资源信息还用于指示所述可用频域资源可作为SDM复用资源。
由于指示可用频域资源可作为SDM复用资源,这样可以实现在IAB DU的可用频域资源与IAB MT的工作带宽发生重叠之前,预先指示潜在的FDM复用,为BWP的切换做准备,以提高切换效率。
作为一种可选地实施方式,所述方法还包括:
所述IAB节点向父节点或者CU上报期望信息,所述期望信息包括如下至少一项:
期望的复用方式、至少一个复用方式对应的频域资源。
上述期望的复用方式可以是FDM或者SDM,也可以是TDM。
上述至少一个复用方式对应的频域资源可以是,每个复用方式对应频域资源大小和位置中的至少一项。
该实施方式中,由于上报上述期望信息,这样可以使得最终获取的资源配置信息与上述期望容易匹配,以最终提高IAB节点的工作性能。
另外,本申请实施例中,CU可以通知上述IAB节点的复用方式,例如:直接通知IAB节点,或者通过父节点通知IAB节点。
作为一种可选地实施方式,所述可用频域资源与所述IAB节点的双工方式相关,所述双工方式包括:所述IAB节点的DU小区上支持的双工方式,或者,所述IAB节点的DU小区和至少一个MT服务小区(MT serving cell)间的双工方式。
本申请实施例中,MT可以支持双连接,如多个MT小区对应一个DU小区。上述DU小区和至少一个MT服务小区间的双工方式可以是,DU小区对应MT服务小区的时候对应不同双工方式,且可以配置不同的DU的可用频域资源。
可选地,不同双工方式相关的可用频域资源为独立获取。
该实施方式中,可以实现对于不同的双工方式,DU的可用频域资源可独立获取或者通知。需要说明的是,这里的不同双工方式并不是指所有双工方式,因为,在一些场景中,不排除一部分双工方式无需获取或者通知DU的可用频域范围。
可选地,所述IAB的DU与MT的复用方式与所述双工方式相关。
其中,上述相关可以包括如下至少一项:
当MT发送(MT发射端口(Transmit X,TX))和DU发送(DU TX)同时发生时或者支持MT TX和DU TX同时发生时,MT TX的频域资源与DU TX的频域资源可以重叠,其中,支持MT和DU同时发送,并不是要求MT和DU一定要同时发送了信号,同时发生可以是指要求实际调度时在相同的时刻同时存在;
当MT接收(MT接收端口(Receive X,RX))和DU接收(DU RX)同时发生时,或者支持MT RX和DU RX同时发生时,MT RX的频域资源与DU RX的频域资源可以重叠;
当MT TX和DU RX同时发生时或者支持MT TX和DU RX同时发生时,MT TX的频域资源与DU RX的频域资源可以重叠,该情况下,可以是默认IAB节点支持全双工,或者,MT TX的频域资源与DU RX的频域资源不重叠,该情况下,可以是默认IAB节点不支持全双工;
当MT RX和DU TX同时发生时或者支持MT RX和DU TX同时发生时,MT RX的频域资源与DU TX的频域资源可以重叠,该情况下,可以是默认IAB节点支持全双工,或者MT RX的频域资源与DU TX的频域资源不重叠,该情况下,可以是默认IAB节点不支持全双工;
若IAB节点支持全双工(或者支持MT TX和DU RX同时发生,或者是MT RX和DU TX同时发生)时,IAB DU的频域范围可以与IAB MT的频 域范围有重叠。
作为一种可选地实施方式,所述方法还包括如下至少一项:
所述IAB节点向父节点上报所述可用频域资源;
所述IAB节点向所述父节点上报所述频域资源信息的获取方式。
其中,上述获取方式也可以理解为父节点或者CU通知频域资源信息的通知方式。
该实施方式中,由于向父节点上报可用频域资源和上述获取方式中的至少一项,这样父节点可以根据IAB DU的可用频域范围,控制IAB MT的BWP和资源调度等中的至少一项,以实现MT和DU间的FDM和SDM复用方式,或确保DU和MT所使用的频域资源间隔满足保护间隔。
在一种实施方式,CU可以通知父节点上述IAB节点的DU的可用频域范围,和/或,CU可以通知父节点上述IAB DU可用频域范围的获取方式/通知方式。该实施方式中,也可以使得父节点可以根据IAB DU的可用频域范围,控制IAB MT的BWP和资源调度等中的至少一项,以实现MT和DU间的FDM和SDM复用方式,或确保DU和MT所使用的频域资源间隔满足保护间隔。
作为一种可选地实施方式,在父节点的DU不调度的频域资源的情况下,所述可用频域资源为所述IAB节点自主确定的。
该实施方式,可以实现当父节点(例如:父节点的IAB-DU)不调度一些频域资源时,上述IAB节点可以自主确定适用这些频域资源,这样可以降低传输开销。例如:IAB节点根据父节点最近调度的最大或者最小的物理资源模块(Physical Resource Block,PRB)序号,确定父节点未来一段时间调度的频域范围,该IAB节点可以调度使用该载波的剩余的频域范围。
作为一种可选地实施方式,所述频域资源信息包括父节点的调度。
其中,上述调度可以是针对IAB节点的MT的调度,也可以是针对IAB节点的DU的调度。
该实施方式中,可以实现通过父节点的调度为IAB节点配置DU的可用频域资源。
作为一种可选地实施方式,
CU通过F1-C信令配置的上述IAB节点的DU在上述IAB节点的MT的PDCCH、搜索空间、控制资源集合、PUCCH中至少一项对应的符号上可用频域范围是基于某个固定的MT工作带宽获取的;或者
父节点通过DCI信令配置的上述IAB节点的DU在上述IAB节点的MT的PDSCH、PUSCH中至少一项对应的符号上的可用频域范围是基于MT的实际的工作带宽获取的;或者
父节点通过DCI信令配置的上述IAB节点的DU在除去上述IAB节点的MT的PDCCH、搜索空间、控制资源集合、PUCCH对应的符号之外符号上的可用频域范围是基于MT的实际的工作带宽获取的。
作为一种可选地实施方式,所述频域资源信息包括所述父节点对所述IAB的MT的第一调度,所述可用频域资源基于所述第一调度确定。
该实施方式中,可以实现根据对MT的调度确定DU的可用频域资源,例如:用调度MT的PDSCH或者PUSCH的PDCCH(例如:DCI)隐式指示IAB节点的DU的可用频域范围。一种方式可以是,对PDCCH中的预留比特重定义来指示,如果该指示为置位,则可以根据PDCCH调度的频域范围来确定未来一段时间父节点不会调度的频域范围作为DU的可用频域资源;或者采用预定义的码点或者码点组合表示为置位,若指示为预定义的码点或码点组合,则可以根据PDCCH调度的频域范围来确定未来一段时间父节点不会调度的频域范围作为可用频域资源。
该实施方式,由于频域资源信息包括所述父节点对所述IAB的MT的第一调度,这样不需要通过额外信令来可用频域资源,从而降低传输开销。
可选地,所述可用频域资源包括:
基于所述第一调度的频域范围中心确定的第一可用频域资源;或者
基于所述第一调度的频域范围确定的第二可用频域资源。
一种实施方式,在所述频域范围中心离所述MT的带宽部分BWP的最低频域资源的距离小于离所述BWP的最高频域资源的距离的情况下,所述第一可用频域资源包括或者属于所述BWP的最高频域资源至所述频域范围的上边界之间的频域资源。
其中,所述第一可用频域资源包括所述BWP的最高频域资源至所述频域 范围的上边界之间的频域资源,表示第一可用频域资源的范围大于等于所述BWP的最高频域资源至所述频域范围的上边界之间的频域资源;所述第一可用频域资源属于所述BWP的最高频域资源至所述频域范围的上边界之间的频域资源,表示第一可用频域资源的范围小于等于所述BWP的最高频域资源至所述频域范围的上边界之间的频域资源。
一种实施方式,在所述频域范围中心离所述MT的带宽部分BWP的最高频域资源的距离小于离所述BWP的最低频域资源的距离的情况下,所述第一可用频域资源包括或者属于所述BWP的最低频域资源至所述频域范围的下边界之间的频域资源。其中,所述第一可用频域资源包括所述BWP的最低频域资源至所述频域范围的下边界之间的频域资源,表示第一可用频域资源的范围大于等于所述BWP的最低频域资源至所述频域范围的下边界之间的频域资源;所述第一可用频域资源属于所述BWP的最低频域资源至所述频域范围的下边界之间的频域资源,表示第一可用频域资源的范围小于等于所述BWP的最低频域资源至所述频域范围的下边界之间的频域资源。
一种实施方式,所述第二可用频域资源包括所述频域范围之外的频域资源。
例如:父节点的IAB-DU调度的频域范围中心PRB更靠近MT BWP的最低频域资源,则确定父IAB-DU未来一段时间不会使用自MT BWP的最高频域资源到调度的频域范围的上边界的频域范围,从而将上述第一可用载频资源确定为包括或者属于该频域范围;
又例如:父节点的IAB-DU调度的频域范围中心PRB更靠近MT BWP的最高频域资源,则确定父IAB-DU未来一段时间不会使用自MT BWP的最低频域资源到调度的频域范围下边界的频域范围,从而将上述第二可用载频资源确定为包括或者属于该频域范围;
又例如:上述IAB节点的DU可以使用父节点的IAB-DU调度的频域范围外的频域资源;
作为一种可选地实施方式,所述频域资源信息包括所述父节点对所述IAB的DU的第二调度,所述可用频域资源基于所述第二调度确定。
该实施方式中,可以实现通过调度为上述IAB节点的DU配置可用频域 资源。例如:父节点发送的调度MT的PDSCH或者PUSCH,该调度传输只用来预留父IAB的DU的频域资源范围。
作为一种可选地实施方式,所述可用频域资源的生效时间由CU或者父节点配置。
该实施方式中,可以实现配置上述可用频域资源只在上述生效时间内生效,以进一步增强对DU的可用频域资源的控制。
可选地,所述CU或者父节点通过如下至少一项指示参数配置所述生效时间:
周期指示、时域偏移、时域资源大小。
例如:CU或者父节点可以向上述IAB节点发送上述至少一项指示参数,以配置上述生效时间。具体可以是通过F1-C信令、RRC信令、回传自适应协议控制分组数据单元(Backhaul Adaptation Protocol control packet data unit,BAP control PDU)、DCI中至少一项配置上述指示参数。另外,指示粒度可以为:M个时隙、N个符号、L毫秒、K个子帧或者A个帧等,其中,M,N,L,K,A>=1。
另外,本申请实施例中,还可以配置IAB节点的MT的工作带宽、IAB节点的保护频带中的至少一项的生效时间。
可选地,在所述可用频域资源为第一双工方式独立配置的情况下,所述可用频域资源仅在生效时间内采用所述第一双工方式的时间有效。
其中,上述第一双工方式可以是预先定义的一种双工方式,对此不作限定。
该实施方式可以实现,在上述生效时间只在有IAB节点工作上述第一双工方式时上述可用频域资源才有效,以进一步增强对DU的可用频域资源的控制。
作为一种可选地实施方式,所述IAB的时频资源在时域指示和频域指示中至少一项指示所述时频资源不可用的情况下,所述时频资源不可用;或者
所述IAB的时频资源在时域指示和频域指示中至少一项指示所述时频资源可用的情况下,所述时频资源可用。
上述时频资源可以是时域资源和频域资源的集合。
其中,上述IAB的时域资源在时域指示和频域指示中至少一项指示所述时频资源不可用的情况下,所述时频资源不可用可以是:

针对上述时频资源,时域指示或频域指示任意一个指示该资源不可用,则该资源不可用。
上述IAB的时域资源在时域指示和频域指示中至少一项指示所述时频资源可用的情况下,所述时频资源可用可以是:
针对上述时频资源,时域指示和频域指示均指示该资源可用,则该资源可用;或者
针对上述时频资源,时域指示或频域指示任意一个指示该资源可用,则该资源可用。
该实施方式中,通过上述方式配置上述时域资源可用或者不可用,可以实现时频域资源的灵活指示。
