- the unavailable (null, N) resource refers to the resource that will not be scheduled by the upper-level node. Those skilled in the art should understand that in actual use, unavailable resources may also be recorded as "NULL", which does not limit the embodiments of the present application.
- the available resources and unavailable resources of the MT may be implicitly deduced by the IAB node through the DU resource type.
- Fig. 3 shows an example of deriving the resource type of the MT from the resource type of the DU.
- the resource types of the DU of the IAB node are unavailable resources, downlink hard resources, and downlink soft resources. Since the resource type of the DU of the IAB node in the first time domain resource is an unavailable resource, it indicates that the DU of the IAB node will not use this time domain resource to transmit signals with subordinate nodes, so the MT of the IAB node can use the first time domain.
- the resource type of the MT of the IAB node in the first time domain resource is an available resource; since the resource type of the DU of the IAB node in the second time domain resource is a downlink hard resource, it indicates that the DU of the IAB node uses the time domain resource It transmits signals with lower-level nodes, so the MT of the IAB node cannot use the second time domain resource, that is, the resource type of the MT of the IAB node in the second time domain resource is an unavailable resource; the DU of the IAB node is in the third time domain resource
- the resource type of is a downlink soft resource, so the upper-level node needs to indicate whether the DU can use the time domain resource, and then further determine whether the MT of the IAB node can use the time domain resource.
- the time domain resource can be a time resource of any length, for example, it can be a time slot, a symbol, a subframe, and so on.
- the upper-level node may indicate the availability of soft resources of the DU of the IAB node through dedicated downlink control information (DCI) (for example, DCI format 2_5).
- DCI downlink control information
- Table 1 shows an example of the DCI dynamic indication value and its meaning. Table 1 takes the time domain resource as an example.
- the DCI only indicates that the symbol whose resource type is a soft resource is available, but does not directly indicate that the symbol whose resource type is a soft resource is unavailable.
- the MT behavior after the DU of the IAB node uses a symbol configured as a soft resource is the same as the MT behavior when the symbol is configured as an unavailable resource of the DU (that is, the use of this symbol by the DU does not affect the MT behavior), or
- the DU of the IAB node can use the symbol configured as a soft resource; otherwise, the DU of the IAB node cannot use the symbol configured as a soft resource.
- the MT resource and DU resource in the IAB node can have different resource reuse types, such as time-division multiplexing (TDM), space division multiplexing (SDM), dynamic SDM, full Duplex multiplexing and other methods.
- TDM time-division multiplexing
- SDM space division multiplexing
- full Duplex multiplexing and other methods.
- the resource configuration of MT resources and the resource configuration of DU resources can have different correspondences. For example, if the resource reuse type is TDM, the MT and DU of the IAB node cannot be transmitted at the same time; if the resource reuse type is SDM, the MT and DU can receive or send at the same time; if the resource reuse type is full duplex, MT and DU can be transmitted at the same time, and are not limited to simultaneous reception or simultaneous transmission.

- a square represents a time slot
- hard resources are resources that are always available to the IAB node DU
- the communication between the upper-level node and the MT of the IAB node needs to avoid the hard resources of the DU.
- time slot 3 and time slot 4 are configured as hard resources of the DU. Therefore, the MT of the IAB node and the superior node perform backhaul link transmission in time slot 1 and time slot 2.
- the resource type of the MT of the IAB node can be correctly derived through the above method.
- the upper-level node 1 and the upper-level node 2 both derive the available MT resources through the resource type of the IAB node's DU, then two The upper-level node will deduce the same MT available resources (as shown in Figure 7), resulting in resource conflicts. Therefore, the single-connection scenario is no longer applicable to the dual-connection scenario.

- the second resource is a resource for the MT of the first node to communicate with the second upper-level node.
- the IAB node when the IAB node derives the available resources of the MT, it should consider that different resource sets may be used when communicating with different upper-level nodes. Specifically, when communicating with the first upper-level node, the IAB node derives the available resources and MT behavior of the MT according to the first configuration information, and when communicating with the second upper-level node, the IAB node derives the MT’s performance based on the second configuration information. Available resources and MT behavior.

- the donor node when the first node has two upper-level nodes, a first upper-level node and a second upper-level node, the donor node provides two configuration information for the first node, and each configuration information corresponds to an upper-level node .
- the first node may determine the resources used for communication between the MT of the first node and the first upper-level node according to the configuration information corresponding to the first upper-level node, and determine the resources used for the first node according to the configuration information corresponding to the second upper-level node The resource for the MT to communicate with the second upper-level node. In this way, as long as the first configuration information and the second configuration information are properly configured, the resource conflict mentioned above can be avoided.
- FIG. 9 is an example of applying the resource configuration method of the embodiment of the present application.
- the first configuration information indicates that the resource types of the DU of the IAB node in time slots 1-4 are soft resources (Soft, S), hard resources (Hard, H), and hard resources.
- the first upper-level node thinks that it can communicate with the MT of the IAB node in time slot 1; and for the second upper-level node, the second configuration information indicates the IAB node
- the resource types of the DU in time slots 1-4 are hard resources, soft resources, hard resources, and hard resources. Therefore, the second upper-level node thinks that it can communicate with the MT of the IAB node in time slot 2, so that the first The resources of the upper-level node and the second-level node to communicate with the IAB node are orthogonal, or there is no conflict.
- the first upper-level node and the second upper-level node may respectively send dynamic resource indication DCI to the IAB node, for example, the DU resource availability indication DCI, that is, the DCI format 2_5 in the existing protocol.

- the IAB node DU can use the third time domain resource, and When the DCI indicates that the third time domain resource is available, the IAB node DU can use the third time domain resource, and When the DCI does not indicate the availability of the third time domain resource, the IAB node thinks that the second upper-level node may communicate with it on the MT resource corresponding to the third time domain resource. If the IAB node DU needs to use the third time domain resource, It cannot affect the communication behavior between the MT and the second superior node. Therefore, the DU of the IAB node should refer to the instruction of the second superior node when determining the availability of the third time domain resource, that is, the third time domain resource is actually the soft resource of the DU.

Abstract
本申请提供了资源配置方法和通信装置,在本申请的技术方案中,donor节点可以为IAB节点以及IAB的两个上级节点配置不同的DU资源配置,使得IAB节点可以根据不同的DU资源配置,确定针对于不同上级节点的MT资源,从而实现双连接场景下的IAB节点的资源配置。
Description
本申请涉及通信领域,并且更具体地,涉及资源配置方法和装置。
随着移动通信技术的不断发展,频谱资源日趋紧张。为了提高频谱利用率,未来的基站部署将会更加密集。此外,密集部署还可以避免覆盖空洞的出现。在传统蜂窝网络架构下,基站通过光纤与核心网建立连接。然而在很多场景下,光纤的部署成本非常高昂。无线中继节点(relay node,RN)通过无线回传链路与核心网建立连接,可节省部分光纤部署成本。
一般情况下,中继节点与一个或多个上级节点建立无线回传链路,并通过上级节点接入核心网。上级节点可通过多种信令对中继节点进行一定的控制(例如,数据调度、定时调制、功率控制等)。另外,中继节点可为多个下级节点提供服务。中继节点的上级节点可以是基站,也可以是另一个中继节点;中继节点的下级节点可以是终端,也可以是另一个中继节点。
5G新空口(new radio,NR)考虑引入接入回传一体化(integrated access and backhaul,IAB)方案以进一步降低部署成本,提高部署灵活性,并由此引入一体化的接入和回传的中继节点,即IAB节点。但是在多跳IAB网络中,由于负载不平衡,链路阻塞等原因,IAB节点上级回传链路可能存在稳定性较差的问题。
针对上述问题,IAB网络引入了双连接技术,即引入冗余链路,以期增加IAB节点上级回传链路的健壮性,并实现负载均衡。但是,在双连接的场景中,尚无对IAB节点进行资源配置的方案。
发明内容
有鉴于此,本申请提供资源配置方法和通信装置,能够实现双连接场景下的IAB节点的资源配置。
第一方面,本申请实施例提供了一种资源配置方法,所述方法包括:第一节点接收来自宿主donor节点的第一配置信息和第二配置信息,所述第一配置信息对应于所述第一节点的第一上级节点,所述第二配置信息对应于所述第一节点的第二上级节点,所述第一配置信息用于指示所述第一节点的分布式单元DU的资源类型,所述第二配置信息用于指示所述第一节点的DU的资源类型,所述资源类型为硬资源、软资源或不可用资源;所述第一节点根据所述第一配置信息,确定第一资源,所述第一资源为所述第一节点的移动终端MT与所述第一上级节点通信的资源;以及,所述第一节点根据所述第二配置信息,确定第二资源,所述第二资源为所述第一节点的MT与所述第二上级节点通信的资源。

结合第一方面和上述任意一种可能的实现方式,在另一种可能的实现方式中,所述第一节点根据所述第一配置信息和所述第二配置信息,确定所述DU的资源类型,包括:当所述第一配置信息和所述第二指示信息中的至少一个指示所述DU在第四时域上的资源类型为不可用资源时,所述第一节点确定所述DU在第四时域上的资源类型为不可用资源。

应理解,本申请中所有节点、消息的名称仅仅是本申请为描述方便而设定的名称,在 实际网络中的名称可能不同,不应理解本申请限定各种节点、消息的名称,相反,任何具有和本申请中用到的节点或消息具有相同或类似功能的名称都视作本申请的方法或等效替换,都在本申请的保护范围之内,以下不再赘述。
考虑到未来无线网络的高带宽,第五代(5th generation,5G)新空口(new radio,NR)或者下一代通信系统考虑引入接入回传一体化(integrated access and backhaul,IAB)方案以进一步降低部署成本,提高部署灵活性,并由此引入一体化的接入和回传的中继,本申请将支持一体化的接入和回传的中继节点称为IAB节点(IAB node)以区分长期演进(long term evolution,LTE)的中继,包含IAB节点的系统又称为中继系统。
为了更好地理解本申请实施例公开的一种资源配置方法和通信装置,下面先对一体化的接入和回传IAB系统进行描述。请参阅图1,图1为本申请实施例所适用的一体化的接入和回传IAB系统的结构示意图。
需要说明的是,本申请实施例提及的通信系统包括但不限于:窄带物联网(narrow band-internet of things,NB-IoT)系统、无线局域网(wireless local access network,WLAN)系统、LTE系统、下一代5G移动通信系统或者5G之后的通信系统,如6G、设备到设备(device to device,D2D)通信系统、车联网。
在图1所示的通信系统中,给出了一体化的接入和回传IAB系统。一个IAB系统至少包括一个基站100,及基站100所服务的一个或多个终端设备(terminal)101,一个或多个中继节点IAB节点,及该IAB节点110所服务的一个或多个终端设备111。通常基站100被称为宿主基站(donor next generation node B,DgNB),IAB节点110通过无线回传链路113连接到基站100。宿主基站在本申请中也称为宿主节点,即,Donor节点。基站包括但不限于:演进型节点B(evolved node base,eNB)、无线网络控制器(radio network controller,RNC)、节点B(node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home node B,HNB)、基带单元(baseband Unit,BBU)、eLTE(evolved LTE,eLTE)基站、NR基站(next generation node B,gNB)、传输接收点(Transmission and Reception Point,TRP)、传输点(Transmission Point,TP)等。终端设备包括但不限于:用户设备(user equipment,UE)、移动台、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、终端、无线通信设备、用户代理、无线局域网(wireless local access network,WLAN)中的站点(station,ST)、蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备、连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的移动台以及未来演进的公共陆地移动网络(public land mobile network,PLMN)网络中的终端设备等中的任意一种。IAB节点是中继节点的特定的名称,不对本申请实施例的方案构成限定,可以是一种具有转发功能的上述基站或者终端设备中的一种,也可以是一种独立的设备形态。
一体化的接入和回传系统还可以包括多个其他IAB节点,例如IAB节点120和IAB节点130,IAB节点120是通过无线回传链路123连接到IAB节点110以接入到网络的,IAB节点130是通过无线回传链路133连接到IAB节点110以接入到网络的,IAB节点120为一个或多个终端设备121服务,IAB节点130为一个或多个终端设备131服务。图 1中,IAB节点110和IAB节点120都通过无线回传链路连接到网络。在本申请中,所述无线回传链路都是从中继节点的角度来看的,比如无线回传链路113是IAB节点110的回传链路,无线回传链路123是IAB节点120的回传链路。如图1所示,一个IAB节点,如120,可以通过无线回传链路,如123,连接另一个IAB节点110,从而连接到网络,而且,中继节点可以经过多级无线中继节点连接到网络。应理解,本申请中用IAB节点仅仅出于描述的需要,并不表示本申请的方案仅用于NR的场景,在本申请中,IAB节点可以泛指任何具有中继功能的节点或设备,本申请中的IAB节点和中继节点的使用应理解具有相同的含义。
为描述方便,以下定义本申请实施例中用到的基本术语或概念。
上级节点:把提供无线回传链路资源的节点,如110,称为IAB节点120的上级节点。应理解,上级节点可以是IAB节点,宿主基站(比如Donor节点),或者网络设备等,对此不作限定。
下级节点:把使用回传链路资源向网络进行数据传输,或者接收来自网络的数据的节点称为下级节点,如,120则称为中继节点110下级节点,131可以成为130的下级节点,网络为核心网或者其他接入网之上的网络,如因特网,专网等。通常,下级节点可以被看作是上级节点的一个终端设备。
接入链路:接入链路是指某个节点和它的下级节点进行通信时所使用的无线链路,包括上行传输和下行传输的链路。接入链路上的上行传输也被称为接入链路的上行传输,下行传输也被称为接入链路的下行传输。其中的节点包括但不限于前述IAB节点。
回传链路:回传链路是指某个节点和它的上级节点进行通信时所使用的无线链路,包括上行传输和下行传输的链路。回传链路上的上行传输也被称为回传链路的上行传输,下行传输也被称为回传链路的下行传输。其中的节点包括但不限于前述IAB节点。
在另外一种描述中,如图2所示,IAB节点可以分为两部分,即移动终端(mobile terminal,MT)和分布式单元(distributed unit,DU)。其中,MT用于IAB节点与上级节点通信,而DU用于IAB节点与下级节点通信。IAB节点中的MT与上级节点的链路被称为上级回传链路(parent BackHaul link),IAB节点中的DU与其下级IAB节点之间的链路被称为下级回传链路(child BackHaul link),而IAB节点中的DU与下属UE之间的链路被称为接入链路(access link)。但在本申请中,为描述方便,IAB节点与上级节点的链路被称为回传链路,IAB节点与下级IAB节点和/或UE的链路被统称为接入链路。
在图1中,无线链路102,112,122,132,113,123,133,134可以是双向链路,包括上行和下行传输链路,特别地,无线回传链路113,123,133,134可以用于上级节点为下级节点提供服务,如上级节点100为下级节点110提供无线回传服务。应理解,回传链路的上行和下行可以是分离的,即,上行链路和下行链路不是通过同一个节点进行传输的。所述下行传输是指上级节点,如节点100,向下级节点,如节点110,传输信息或数据,上行传输是指下级节点,如节点110,向上级节点,如节点100,传输信息或数据。所述节点不限于是网络节点还是终端设备,例如,在D2D场景下,终端设备可以充当中继节点为其他终端设备服务。例如,在车联网场景下,车载模块可以充当中继节点为其他终端设备服务。无线回传链路在某些场景下又可以是接入链路,如回传链路123对节点110来说也可以被视作接入链路,回传链路113也是节点100的接入链路。应理解,上述 上级节点可以是基站,也可以是中继节点,下级节点可以是中继节点,也可以是具有中继功能的终端设备,如D2D场景下,下级节点也可以是终端设备。
图1所示的中继节点,如110,120,130,可以有两种存在的形态:一种是作为一个独立的接入节点存在,可以独立管理接入到中继节点的终端设备,此时的中继节点通常具有独立的物理小区标识(physical cell identifier,PCI),这种形态的中继通常需要有完全的协议栈功能,比如无线资源控制(radio resource control,RRC)的功能,这种中继通常被称为层3中继;而另一种形态的中继节点和Donor节点,如Donor eNB,Donor gNB,属于同一个小区,用户的管理是由宿主基站,如Donor节点来进行管理的,这种中继通常被称为层2中继。层2中继在NR的控制和承载分离(central unit and Distributed unit,CU-DU)架构下通常作为基站DgNB的DU而存在,通过F1应用协议(F1application protocol,F1-AP)接口或者隧道协议和CU进行通信,其中隧道协议可以是例如通用分组无线服务技术隧道协议(general packet radio service tunneling protocol,GTP)协议,不再赘述。Donor节点是指通过该节点可以接入到核心网的节点,或者是无线接入网的一个锚点基站,通过该锚点基站可以接入到网络。锚点基站负责接收核心网的数据并转发给中继节点,或者接收中继节点的数据并转发给核心网。通常,把中继系统中的Donor节点称为IAB Donor,即宿主节点,本申请中两个名词可能会交替使用,应理解,不应理解IAB donor和宿主节点是具有不同功能的实体或网元。
在本申请实施例中,中继节点(如IAB节点)或终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层,以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit,CPU)、内存管理单元(memory management unit,MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统,例如,Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且,本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定,只要能够通过运行记录有本申请实施例的提供的方法的代码的程序,以根据本申请实施例提供的方法进行通信即可,例如,本申请实施例提供的方法的执行主体可以是终端设备或网络设备,或者,是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外,本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,压缩盘(compact disc,CD)、数字通用盘(digital versatile disc,DVD)等),智能卡和闪存器件(例如,可擦写可编程只读存储器(erasable programmable read-only memory,EPROM)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
为了便于理解,这里对本申请实施例涉及到的一些术语或概念进行解释。
DU资源:是指IAB节点DU功能所使用的资源。DU资源可以被配置为上行(uplink,U)资源、下行(downlink,D)资源和灵活(flexible,F)资源。进一步的,DU的上行 资源、下行资源和灵活资源又可以进一步分为软(soft,S)资源、硬(hard,H)资源和不可用资源(not available)。
软资源:是指资源是否可由DU使用,取决于上级节点的指示。
硬资源:表示DU始终可用的资源。
不可用资源:表示DU始终不可用的资源。
在本申请中,DU的软资源、硬资源和不可用资源可以是由上级节点通过高层信令(例如RRC信令)或接口消息(例如F1-AP接口消息或增强的F1-AP接口消息)显式配置。
MT资源:是指IAB节点MT功能所使用的资源。MT资源可以被配置为上行(uplink,U)资源、下行(downlink,D)资源和灵活(flexible,F)资源。
此外,MT资源还可分为以下两种类型:
可用资源,是指可能被上级节点调度的资源;
不可用(null,N)资源,是指不会被上级节点调度的资源。本领域技术人员应理解,在实际使用中,不可用资源也可以记作“NULL”,这不对本申请实施例造成限定。
在本申请实施例中,MT的可用资源和不可用资源可以由IAB节点通过DU资源类型隐式推导得出的。图3示出了由DU的资源类型推导MT的资源类型的一个示例。
如图3所示,以3个时域资源为例,IAB节点的DU的资源类型分别为不可用资源、下行硬资源和下行软资源。由于IAB节点的DU在第一个时域资源的资源类型为不可用资源,表明IAB节点的DU不会使用该时域资源与下级节点传输信号,所以IAB节点的MT可以使用第一个时域资源,即IAB节点的MT在第一时域资源的资源类型为可用资源;由于IAB节点的DU在第二个时域资源的资源类型为下行硬资源,表明IAB节点的DU使用该时域资源与下级节点传输信号,所以IAB节点的MT不能使用第二个时域资源,即IAB节点的MT在第二时域资源的资源类型为不可用资源;IAB节点的DU在第三个时域资源的资源类型为下行软资源,所以需要上级节点指示DU是否可以使用该时域资源,之后进一步确定IAB节点的MT是否可以使用该时域资源。其中,时域资源可以是任意长度的时间资源,例如,可以是时隙、符号、子帧等。
上级节点可以通过专用下行控制信息(downlink control information,DCI)(例如,DCI format 2_5)指示IAB节点的DU的软资源的可用性。表1给出了DCI动态指示取值及其表示的含义的一个示例,表1中以时域资源为符号为例。
表1
取值 | 指示 |
0 | 没有软类型的符号被指示为可用 |
1 | 仅下行软类型的符号被指示为可用 |
2 | 仅上行软类型的符号被指示为可用 |
3 | 仅下行和上行软类型的符号被指示为可用 |
4 | 仅灵活软类型的符号被指示为可用 |
5 | 仅下行和灵活软类型的符号被指示为可用 |
6 | 仅上行和灵活软类型的符号被指示为可用 |
7 | 上行、下行和灵活软类型的符号被指示为可用 |
可以注意到,DCI仅指示资源类型为软资源的符号可用,而不会直接指示资源类型为 软资源的符号不可用。当IAB节点的DU使用被配置为软资源的符号后的MT行为与该符号被配置为DU的不可用资源时的MT行为相同(即DU对此符号的使用不影响MT行为)时,或者该符号被专用DCI指示为可用时,IAB节点的DU可以使用该被配置为软资源的符号,否则,IAB节点的DU不能使用被配置为软资源的符号。
IAB节点中的MT资源和DU资源可以存在不同的资源复用类型,比如,时分多路复用(time-division multiplexing,TDM),空分复用(space division multiplexing,SDM),动态SDM,全双工复用等方式。在不同的资源复用类型下,MT资源的资源配置与DU资源的资源配置可具备不同的对应关系。例如,若资源复用类型是TDM,IAB节点的MT和DU不能进行同时传输;若资源复用类型是SDM,MT与DU可进行同时接收或同时发送;若资源复用类型是全双工,MT与DU可进行同时传输,且不限制为同时接收或同时发送。
应理解,图1所示的一体化接入和回传系统中,一个IAB节点连接一个上级节点。但是在多跳一体化接入和回传系统中,由于负载不平衡,链路阻塞等原因,IAB节点上级回传链路可能存在稳定性较差的问题。针对上述问题,引入了双连接技术,即引入冗余链路,以期增加IAB节点上级回传链路的健壮性,并负载均衡。
图4示出了双连接场景的一个例子的示意图。如图4所示,IAB节点1可以通过回传链路1连接到IAB节点2,并通过IAB节点2接入到网络;IAB节点1还可以通过回传链路3连接到IAB节点3,并通过IAB节点3接入到网络。也就是说,IAB节点2和IAB节点3都为IAB节点1的上级节点。IAB节点1,2,3的名称并不限制其所部署的场景或网络,可以是比如relay,RN等任何其他名称。本申请使用IAB节点仅是方便描述的需要。
在图4中,IAB节点的两个上级节点均为IAB节点,在实际部署中,任意一个上级节点可能为IAB节点,也可能为普通基站。当两个上级节点为IAB节点时,它们可能具有相同的宿主节点,也可能具有不同的宿主节点。本申请实施例对上级节点的类型以及网络部署不做具体限定,只要IAB节点具有两个上级节点即可。
在单连接场景,即IAB节点只有一个上级节点的场景下,如图5的(a)图所示的场景下,donor节点会为IAB节点和IAB节点的上级节点提供IAB节点的DU的资源类型(当上级节点不是donor节点时),而后IAB节点和IAB节点的上级节点根据donor节点提供的IAB节点的DU的资源类型,确定IAB节点的MT的资源类型,从而进行回传链路的通信。图6是单连接场景下IAB节点根据IAB节点的DU的资源类型确定IAB节点的MT的资源类型的一个示例。在图6中,以时隙为例,一个方块代表一个时隙,考虑IAB节点的MT与DU的4个时隙。由于硬资源是IAB节点DU始终可用的资源,因此上级节点与IAB节点的MT的通信需要避开DU的硬资源。图6中,时隙3与时隙4被配置为DU的硬资源,因此,IAB节点的MT与上级节点在时隙1与时隙2进行回传链路传输。
当IAB节点仅有一个上级节点时,通过上述方式可以正确推导出IAB节点的MT的资源类型。但是在IAB节点存在两个上级节点时,如图5的(b)图所示的场景,上级节点1和上级节点2若均通过IAB节点的DU的资源类型推导可用的MT资源,则两个上级节点会推导出同样的MT可用资源(如图7所示),导致资源冲突。因此,单连接场景的方案不再适用于双连接场景。
针对上述问题,本申请实施例提供了资源配置方法和通信装置,能够实现双连接场景 下的IAB节点的资源配置。
图8是本申请实施例提供的资源配置方法的示意性流程图。图8所示的方法包括以下内容的至少部分内容。
在810中,donor节点确定第一配置信息和第二配置信息。其中,所述第一配置信息对应于所述第一节点的第一上级节点,所述第二配置信息对应于所述第一节点的第二上级节点,所述第一配置信息用于指示所述第一节点的DU的资源类型,所述第二配置信息用于指示所述第一节点的DU的资源类型。
所述资源类型可以为上文所述的硬资源、软资源或不可用资源。
在820中,donor节点向第一节点发送第一配置信息和第二配置信息,相应地,第一节点接收来自donor节点的第一配置信息和第二配置信息。
所述第一节点可以是中继节点,比如IAB节点。
在820中,第一节点根据第一配置信息,确定第一资源,根据第二配置信息,确定第二资源。其中,第一资源为第一节点的MT与第一上级节点通信的资源,第二资源为第一节点的MT与第二上级节点通信的资源。
也就是说,在IAB节点在推导MT的可用资源时,应考虑与不同上级节点通信时可能采用不同的资源集合。具体地,在与第一上级节点进行通信时,IAB节点根据第一配置信息推导MT的可用资源以及MT行为,而在与第二上级节点进行通信时,IAB节点根据第二配置信息推导MT的可用资源及MT行为。
在一种可能的实现方式中,第一配置信息指示第一节点的DU在第一时域上的资源类型为第一类型,第二配置信息指示第一节点的DU在第一时域资源上的资源类型为第二类型,第一类型与第二类型不同。也就是说,第一配置信息和第二配置信息不同。这样,IAB节点根据第一配置信息确定出的第一资源和根据第二配置信息确定出的第二资源不同。而对于IAB节点的上级节点,donor节点可以向第一上级节点发送第一配置信息,向第二上级节点发送第二配置信息。第一上级节点可以根据第一配置信息,确定第一资源,当与IAB节点的MT进行通信时则使用第一资源;第二上级节点可以根据第二配置信息,确定第二资源,当与IAB节点的MT进行通信时则使用第二资源。这样就能够避免上文提到的资源冲突。
第一资源和第二资源不同,也就是说,第一资源和第二资源不重叠。例如,第一资源和第二资源在时域上是时分复用的或者满足时域正交化条件的。
在本申请的技术方案中,当第一节点有第一上级节点和第二上级节点两个上级节点的时候,donor节点为第一节点提供两个配置信息,每个配置信息对应于一个上级节点。第一节点可以根据与第一上级节点对应的配置信息,确定用于第一节点的MT与第一上级节点通信的资源,根据与第二上级节点对应的配置信息,确定用于第一节点的MT与第二上级节点通信的资源。这样,只要合理地配置第一配置信息和第二配置信息,就可以避免上文提到的资源冲突。
图9是应用本申请实施例的资源配置方法的一个示例。在图9中,以第一节点为IAB节点,时域资源为时隙为例,一个方块代表一个时隙,考虑IAB节点的MT与DU的4个时隙。如图9所示,对于第一上级节点,第一配置信息指示IAB节点的DU在时隙1-4上的资源类型分别为软资源(Soft,S)、硬资源(Hard,H)、硬资源(Hard,H)、硬资源(Hard, H),因此,第一上级节点认为其可以在时隙1与IAB节点的MT进行通信;而对于第二上级节点,第二配置信息指示IAB节点的DU在时隙1-4上的资源类型分别为硬资源、软资源、硬资源、硬资源,因此,第二上级节点认为其可以在时隙2与IAB节点的MT进行通信,从而第一上级节点和第二上级节点与IAB节点通信的资源实现了正交,或者说无冲突。
在一些实施例中,第一上级节点和第二上级节点可能分别为IAB节点发送动态资源指示DCI,例如,DU资源可用性指示DCI,即现有协议中的DCI格式2_5。当IAB节点具有两个分别对应于与不同上级节点的DU资源类型时,任一上级节点发送的动态资源指示应基于与其对应的DU资源类型。例如,第一上级节点发送的动态资源指示仅指示DU资源类型中类型为软资源的可用性,或者IAB节点认为第一配置信息指示的DU资源类型中类型为软资源的可用性由第一上级节点发送的DCI所指示,或IAB节点认为第一上级节点发送的动态资源指示DCI仅指示第一配置信息所指示的软资源的可用性;第二上级节点发送的动态资源指示仅指示DU资源类型中类型为软资源的可用性,或者IAB节点认为第二配置信息指示的DU资源类型中类型为软资源的可用性由第二上级节点发送的DCI所指示,或IAB节点认为第二上级节点发送的动态资源指示DCI仅指示第二配置信息所指示的软资源的可用性。示例性地,对于第一资源配置指示的软资源,如果第一上级节点发送的动态资源指示不对其可用性加以指示,IAB节点仅可以在不影响其MT与第一上级节点通信行为的前提下可以使用此DU软资源;对于第二资源配置指示的软资源,如果第二上级节点发送的动态资源指示不对其可用性加以指示,IAB节点仅可以在不影响其MT与第二上级节点通信行为的前提下可以使用此DU软资源。
在一种可能的实现方式中,第一配置信息和第二配置信息均指示一个DU资源为软资源,此时,当且仅当第一上级节点和第二上级节点均指示该时域资源为可用资源时,第一节点认为该时域资源为DU的可用资源。而当任一上级节点不对此时域资源的可用性进行指示时,IAB节点仅可以在不影响其MT与该上级节点通信行为的前提下可以使用此DU软资源。
在上述方案下,IAB节点收到关于其DU的第一配置信息和第二配置信息两个配置信息,因此IAB节点需要综合第一配置信息和第二配置信息来确定DU的实际资源类型。
当第一配置信息指示DU在第二时域资源上的资源类型为硬资源,同样第二配置信息指示DU在第二时域资源上的资源类型为硬资源时,即第二时域资源对于第一上级节点和第二上级节点均是硬资源时,IAB节点可确定第一上级节点和第二上级节点均认为第二时域资源为IAB节点的可用资源,即第二时域资源实际是DU的硬资源。
当第一配置信息指示DU在第三时域资源上的资源类型为硬资源,而第二配置信息指示DU在第三时域资源上的资源类型为软资源时,即第三时域资源对于第一上级节点是硬资源,对于第二上级节点是软资源时,IAB节点可确定第一上级节点不会对第三时域资源的可用性做出指示,而第二上级节点有可能通过DCI指示第三时域资源的可用性,此时第三时域资源的可用性由第二上级节点发送的DCI指示,当DCI指示第三时域资源可用时,IAB节点DU可使用第三时域资源,而当DCI不对第三时域资源的可用性加以指示时,IAB节点认为第二上级节点有可能在与第三时域资源对应的MT资源与其进行通信,若IAB节点DU需要使用第三时域资源,则不能影响MT与第二上级节点的通信行为。因此,IAB 节点的DU在确定第三时域资源的可用性时,应该参考第二上级节点的指示,即第三时域资源实际是DU的软资源。同理,当第一配置信息指示DU在第三时域资源上的资源类型为软资源,而第二配置信息指示DU在第三时域资源上的资源类型为硬资源时,第三时域资源实际是DU的软资源。或者,当第一配置信息指示DU在第三时域资源上的资源类型为软资源,而第二配置信息指示DU在第三时域资源上的资源类型为软资源时,即第三时域资源对于第一上级节点和第二上级节点均是软资源时,IAB节点可确定第一上级节点和第二上级节点均有可能通过DCI指示第三时域资源的可用性,从而IAB节点认为第一上级节点和第二上级节点均有可能在与第三时域资源对应的MT资源与其进行通信。因此,IAB节点的DU在确定第三时域资源的可用性时,应该参考第一上级节点和第二上级节点的指示,即第三时域资源实际是DU的软资源。
当第一配置信息指示DU在第四时域资源上的资源类型为不可用资源,第二配置信息指示DU在第四时域资源上的资源类型为硬资源、软资源或不可用资源时,即第四时域资源对于第一上级节点是不可用资源,对于第二上级节点是硬资源、软资源或者不可用资源时,IAB节点确定DU不能使用第四时域资源,即第四时域资源实际是DU的不可用资源。同理,当第一配置信息指示DU在第四时域资源上的资源类型为硬资源、软资源或不可用资源,第二配置信息指示DU在第四时域资源上的资源类型为不可用资源时,第四时域资源实际是DU的不可用资源。在另一种可能的实现方式中,第一资源配置和第二资源配置所指示的不可用资源相同,即IAB节点不期望一个资源被第一资源配置指示为不可用,而被第二资源配置指示为硬资源或软资源,反之亦然。
表2示出了所有资源类型组合后实际的资源类型。
表2
在一种可能的实现方式中,可以在协议中定义上述资源类型组合后实际的资源类型。例如,协议可以仅定义硬资源与其它类型的资源组合后实际的资源类型,而不定义其他资源类型组合后实际的资源类型。又例如,协议可以定义如表2所示的所有资源类型的组合后实际的资源类型。
在另一种可能的实现方式中,协议也可将资源类型的组合留作IAB节点DU的实现,即协议不显式地定义上述各资源类型组合后实际的资源类型。
基于上文可知,在双连接场景下,DU的资源配置会存在三种资源配置:
1、第一配置信息指示的第一资源配置;
2、第二配置信息指示的第二资源配置;
3、根据第一配置信息和第二配置信息确定的第三资源配置。
上文所述的各实施例均以第一资源配置为对应于第一上级节点的资源配置,第二资源配置为对应于第二上级节点的资源配置,第三资源配置为DU实际的资源配置为例进行描述的,如图10所示。
IAB节点根据第一资源配置确定与第一上级节点进行通信的资源,根据第二资源配置确定与第二上级节点进行通信的资源,根据第三配置确定其DU与下级节点或UE进行通信的资源。对应的,第一上级节点和第二上级节点应根据第一资源配置和第二资源配置确定其与IAB节点进行通信的资源。为了达到此目的,宿主节点可以将第一资源配置信息和第二资源配置信息发送至第一上级节点和第二上级节点,即为第一上级节点和第二上级节点发送子节点DU配置,这里的子节点表示IAB节点。
在一种可能的实现方式中,宿主节点为第一上级节点发送IAB节点DU的第一资源配置,为第二上级节点发送IAB节点DU的第二资源配置。第一上级节点根据第一资源配置与IAB节点进行通信,而第二上级节点根据第二资源配置与IAB节点进行通信。在这种情况下,上级节点与IAB节点通信时资源的确定方式与单连接场景相同。
在另一种可能的实现方式中,宿主节点为第一上级节点和第二上级节点发送IAB节点DU的第一资源配置和第二资源配置。第一上级节点根据第一资源配置与IAB节点进行通信,而第二上级节点根据第二资源配置与IAB节点进行通信。同样的,上级节点与IAB节点通信时资源的确定方式与单连接场景相同。
在另一些可能的实现方式中,第一资源配置可以为DU实际的资源配置,第二资源配置为对应于第一上级节点或者第二上级节点的资源配置,第三资源配置为对应于第二上级节点或者第一上级节点的资源配置;或者,第一资源配置可以为对应于第一上级节点或者第二上级节点的资源配置,第二资源配置为DU实际的资源配置,第三资源配置为对应于第二上级节点或者第一上级节点的资源配置。
以第一资源配置可以为DU实际的资源配置,第二资源配置为对应于第二上级节点的资源配置,第三资源配置为对应于第一上级节点的资源配置为例。IAB节点可以分别获取第一配置信息和第二配置信息,以便推导出第三资源配置,即对应于第一上级节点的资源配置;第一上级节点可以获取第一配置信息;第二上级节点可以分别获取第一配置信息和第二配置信息,以便推导出第三资源配置,即对应于第一上级节点的资源配置;第一上级节点获取到第二资源配置和第三资源配置,而第二上级节点获取到第二资源配置。
图11是本申请实施例提供另一种资源配置方法的示意性流程图。图11所示的方法包括以下内容的至少部分内容。
在1110中,donor节点确定第四配置信息、第一指示信息和第二指示信息。其中,所述第四配置信息用于指示第一节点的DU的资源类型,所述第一指示信息用于指示所述第一节点的第一上级节点的DU的不可用资源所在时域位置,所述第二指示信息用于指示所述第一节点的第二上级节点的DU的不可用资源所在时域位置。
第一指示信息可以指示为第一上级节点配置的链路级的不可用资源。
第二指示信息可以指示为第二上级节点配置的链路级的不可用资源。
应理解,链路级不可用资源表示该不可用资源仅适用于特定链路,例如,第一指示信息指示第一上级节点和第一节点之间链路的不可用资源,第二指示信息指示第二上级节点和IAB节点之间链路的不可用资源。一个资源对于特定链路为不可用资源,但对于其余链路可能为可用资源。
Donor节点向第一上级节点发送第一节点的DU的资源类型和第一指示信息;Donor节点向第二上级节点发送第一节点的DU的资源类型和第二指示信息。
可选地,donor节点可以通过F1-AP接口向第一节点发送第一指示信息和第二指示信息。在各上级节点的链路级NA配置是逐上级节点DU小区配置的情况下,IAB节点可能无法获知上级节点DU小区与第一节点的MT分量载波、MT服务小区(MT serving cell)或者DU小区的对应关系。因此,上级节点或donor节点还需向第一节点通知上级节点DU小区与第一节点的MT的分量载波之间的对应关系、上级节点DU小区与IAB节点的MT服务小区之间的对应关系或上级节点DU小区与IAB节点的DU小区之间的对应关系。
可选地,donor节点也可经由上级节点通过接口信令或空口信令发送给第一节点。
在1120中,donor节点向第一节点发送所述第四配置信息、第一指示信息和第二指示信息,相应地,第一节点接收来自donor节点的第四配置信息、第一指示信息和第二指示信息。
在1130中,第一节点根据第四配置信息和第一指示信息,确定第三资源,根据第四配置信息和第二指示信息,确定第四资源。其中,所述第三资源为所述第一节点的MT与所述第一上级节点通信的资源,所述第四资源为所述第一节点的MT与所述第二上级节点通信的资源。
可选的,第一指示信息和第二指示信息指示的不可用资源的时域位置不同。
对于第一上级节点,donor节点可以向第一上级节点发送第四配置信息和第一指示信息,以便第一上级节点确定与第一节点的MT进行通信使用的资源。对于第二上级节点,donor节点可以向第二上级节点发送第四配置信息和第二指示信息,以便第二上级节点确定与第一节点的MT进行通信使用的资源。
也就是说,在本申请实施例中,donor节点为各个上级节点配置链路级的不可用资源。第一节点在接收到第四配置信息、第一指示信息和第二指示信息后,分别确定MT与不同上级节点通信时使用的资源。第一上级节点在接收到第四配置信息和第一指示信息之后,确定与第一节点通信时使用的资源。第二上级节点在接收到第四配置信息和第二指示信息之后,确定与第一节点通信时使用的资源。
图12是应用本申请实施例的资源配置方法的一个示例。在图12中,以第一节点为IAB节点,时域资源为时隙为例,一个方块代表一个时隙,考虑IAB节点的MT与DU的4个时隙。如图12所示,第四配置信息指示IAB节点的DU在时隙1-4上的资源类型分别为软资源、软资源、硬资源、硬资源;对于第一上级节点,第一指示信息指示第一上级节点的DU在时隙2上为不可用资源;对于第二上级节点,第二指示信息指示第二上级节点的DU在时隙1上为不可用资源。IAB节点、第一上级节点和第二上级节点除了根据第四配置信息确定IAB节点的MT的部分不可用资源(如图12中的时隙3和4),还通过第一指示信息和/或第二指示信息额外确定了IAB节点的MT的部分不可用资源,例如,IAB节点额外确定了不在时隙2与第一上级节点进行通信,不在时隙1与第二上级节点进行通信。
在图11中,第一节点通过接收来自donor节点的第一指示信息和第二指示信息,来进一步确定分别与不同上级节点进行通信的资源。除了如图11所示的方式,第一节点还可以通过接收来自第一上级节点的第一动态资源指示和来自第二上级节点的第二动态资源指示,来进一步确定分别与不同上级节点进行通信的资源,其中,第一动态资源指示是第一上级节点根据第一指示信息确定的,第二动态资源指示是第二上级节点根据第二指示 信息确定的。IAB节点可以获知各上级节点不会在指示为DU可用的资源上与自己进行通信。
第一动态资源指示和第二动态资源指示可以通过专用DCI来指示,例如,通过DCI format 2_5来指示。
图13示出了IAB节点根据动态资源指示进一步通信资源的一个示例。在图13中,以第一节点为IAB节点,时域资源为时隙为例,一个方块代表一个时隙,考虑IAB节点的MT与DU的4个时隙。第一上级节点在时隙2对于IAB节点是不可用资源,因此,第一上级节点在第一动态资源指示中将时隙2指示为IAB节点的DU的可用资源,则IAB节点可推断出第一上级节点不会在该可用资源对应的MT的资源与自己进行通信;第二上级节点在时隙1对于IAB节点是不可用资源,因此,第二上级节点在第二动态资源指示中将时隙1指示为IAB节点的DU的可用资源,则IAB节点可推断出第二上级节点不会在该可用资源对应的MT的资源与自己进行通信,从而达到针对多上级节点资源分割的目的。
同样,在此实施例中第一节点的DU的实际可用资源需要综合第一上级节点和第二上级节点的动态资源指示。具体地,当且仅当第一上级节点和第二上级节点均指示第五时域资源为可用资源时,第一节点认为第五时域资源为DU的可用资源。而当任一上级节点不对第五时域资源的可用性进行指示时,IAB节点仅可以在不影响其MT与该上级节点通信行为的前提下可以使用此DU软资源。
在一种可能的实现方式中,若donor节点为第一节点发送了第一指示信息和第二指示信息,且第一上级节点或第二上级节点的DU资源为链路级不可用资源,则IAB节点可以忽略该上级节点在对应IAB节点的DU资源的动态资源指示。
图14是本申请实施例提供的又一种资源配置方法的示意性流程图。图14所示的方法包括以下内容的至少部分内容。
在1410中,第一节点确定第一信息和第二信息。其中,第一信息对应于第一上级节点,第二信息对应于第二上级节点,第一信息用于指示关联到第一上级节点的第一节点的MT的载波与第一节点的DU的小区之间的复用能力,第二信息用于指示关联到第二上级节点的第一节点的MT的载波与第一节点的DU的小区之间的复用能力。在第一信息中,MT的载波是MT与第一上级节点通信时采用或被配置的载波。在第二信息中,MT的载波是MT与第二上级节点通信时采用或被配置的载波。
由于不同上级节点与第一节点的MT通信时可能采用不同(朝向)的天线面板,所以针对于不同的上级节点,第一节点的MT的载波与第一节点的DU的小区之间可能具有不同的复用能力。基于此,在1410中,针对不同的上级节点,第一节点分别确定第一节点的MT的载波与第一节点的DU的小区之间的复用能力。
可选地,上述复用能力为第一能力、第二能力、第三能力、第四能力或第五能力,其中,第一能力指示MT发送信号与DU发送信号能够同时进行,第二能力指示MT发送信号与DU接收信号能够同时进行,第三能力指示MT接收信号与DU发送信号能够同时进行,第四能力指示MT接收信号与DU接收信号能够同时进行,第五能力指示MT与DU不能同时接收信号或者发送信号。
在1420中,第一节点向donor节点发送所述第一信息和所述第二信息,相应地,donor节点接收来自第一节点的第一信息和第二信息。即,针对不同上级节点,第一节点向donor 节点上报的MT的载波与DU的小区之间的复用能力。
在一些实施例中,第一节点可以通过接口信令直接将第一信息和第二信息上报至donor节点。在此情况下,第一节点的上报的第一信息和第二信息应该使得donor节点能够区别第一信息和第二信息所对应的上级节点。
可选地,第一节点可以通过不同的信令发送第一信息和第二信息,以指示或区分不同的上级节点。
可选地,第一节点可以在上报第一信息和/或第二信息的信令中携带对应的上级节点的标识,以指示或区分不同的上级节点。
可选地,第一节点可以在第一信息和/或第二信息中携带对应的上级节点的标识,以指示或区分不同的上级节点。
对于第一节点,双连接可以通过以下两种方式实现。
方式1,第一节点的单个MT连接不同的上级节点,MT与第一上级节点(主连接节点)通信的小区组被称为主小区组(master cell group,MCG),而与第二上级节点(辅连接节点)信的小区组被称为次小区组(secondary cell group,SCG)。小区组表示MT进行载波聚合采用的多个小区、服务小区(serving cell)或者分量载波。在此情况下,donor节点、上级节点或第一节点可以通过小区组来指示或区分上级节点。
方式2,第一节点还可以通过多个MT模块实现双连接。不同的MT模块与不同的上级节点进行通信,形成不同的小区组。此外,由于多个MT为独立模块,不同MT模块的小区组可以不进行MCG与SCG的区分。在此情况下,donor节点、上级节点或第一节点可以通过小区组来指示或区分上级节点,也可以通过MT的标识来指示或区分上级节点,MT的标识包括无线网络临时标识(radio network tempory identity,RNTI),MT ID等。
综上,本申请实施例可以通过不同的信令、上级节点的标识、上级节点小区ID,上级节点小区物理ID、主小区组/次小区组、Pcell标识/sPcell标识等指示或区分上级节点。
在一些实施例中,第一节点还向第一上级节点上报第一信息,向第二上级节点上报第二信息。
可选地,第一节点可以通过接口信令或空口信令,将第一信息发送给第一上级节点,将第二信息发送给第二上级节点。
可选地,第一节点也可以先将第一信息和第二信息发送给donor节点后,再由donor节点分别将其发送至对应的上级节点。
第一节点具有同时与多个上级节点进行收发的能力。在一些实施例中,为了使第一节点与通过不同的天线面板与不同的上级节点进行通信互不影响,第一节点还可以向donor或者两个上级节点上报第三信息。第三信息用于指示第一链路和第二链路的复用类型,其中,第一链路为第一节点的MT与第一上级节点之间的通信链路,第二链路为第一节点的MT与第二上级节点之间的通信链路。
可选地,第三信息可以指示第一链路与第二链路是否需要时域和/或频域的正交化或隔离处理。
可选地,第三信息可以是与不同上级节点连接的MT小区之间的复用类型。
可选地,第三信息可以指示第一节点是否支持带内DC的同时传输。在这里,带内DC表示IAB节点MT采用同样频段的分量载波(或服务小区)与不同的上级节点进行通 信。
可选地,第一链路和第二链路的复用类型可以表示为MT的MCG的复用类型和SCG的复用类型。
可选地,上述复用类型为时分复用TDM、空分复用SDM、动态SDM或全双工复用等。
由于与不同上级节点连接时,第一节点的MT与DU切换所需要的保护符号数目可能不同,因此,在一些实施例中,针对不同的上级节点,第一节点还可以分别确定并上报与上级节点相对应的保护符号信息。
需要说明的是,上述各实施例仅以第一节点具有两个上级节点为例,本申请的各实施也可以应用于第一节点具有更多上级节点的场景下。上述各实施例可以单独实施,也可以合理地结合在一起实施。
可以理解的是,为了实现上述实施例中功能,通信装置包括了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到,结合本申请中所公开的实施例描述的各示例的单元及方法步骤,本申请能够以硬件或硬件和计算机软件相结合的形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用场景和设计约束条件。
