目前,在通信传输过程中,网络设备需要基于终端设备上报的终端能力信息进行调度,例如,网络设备可以基于终端设备上报的能够支持的传输流数,码字数等对终端设备进行调度。
其中,为了有效提高传输质量,在进行上下行数据传输时,网络设备和终端设备经常采用一个或一组波束进行上行传输,当采用一组波束时,该一组波束可以位于不同的天线面板(antenna panel)上,例如,通过多个panel上的各一个波束进行上行传输,各波束可以同时传输,也可以分时传输;该一组波束也可以位于同一个panel,此时该组波束中的各个波束只能进行分时传输。
然而,网络设备基于目前终端设备上报的终端能力信息,在上行传输调度中,经常存在终端设备采用的上行传输波束或波束组无法支持网络设备的传输调度,使得通信传输失败率较高。
综上,目前亟需一种高效、适用性更强的通信传输方法。

下面结合说明书附图对本申请进行具体说明。
本申请实施例提供的通信方法可以应用于第四代(4th generation,4G)通信系统,例如长期演进(long term evolution,LTE),也可以应用于第五代(5th generation,5G)通信系统,例如5G新空口(new radio,NR),或应用于未来的各种通信系统,例如,第六代(6th generation,6G)通信系统。
本申请实施例提供的方法和装置是基于同一或相似技术构思的,由于方法及装置解决问题的原理相似,因此装置与方法的实施可以相互参见,重复之处不再赘述。
以下,首先对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
1)本申请实施例中涉及的资源,可以是上行信号资源,也可以是下行信号资源。
其中,上行信号包括但不限于探测参考信号(sounding reference signal,SRS),解调参考信号(demodulation reference signal,DMRS)。
下行信号包括但不限于:
信道状态信息参考信号(channel state information reference signal,CSI-RS)、小区专用参考信号(cell specific reference signal,CS-RS)、UE专用参考信号(user equipment specific reference signal,US-RS)、解调参考信号(demodulation reference signal,DMRS)、以及同步信号/物理广播信道块(synchronization system/physical broadcast channel block,SS/PBCH block)。
其中,在本申请实施例中所述的资源包括并不限于波束,所述的资源组包括并不限于波束组。
可以理解的,在波束测量中,波束和资源是有对应关系的(例如,网络设备采用一个波束发送其对应的资源),终端设备测量该资源的质量即等于测量该波束的质量,因此,本申请实施例所述的资源或资源组可以为波束或波束组。
2)本申请实施例中涉及的波束,是一种通信资源,不同的波束可以认为是不同的资源。
波束可以称为空域滤波器(spatial domain filter),空间滤波器(spatial filter),空域参数(spatial domain parameter),空间参数(spatial parameter),空域设置(spatial domain setting),空间设置(spatial setting),准共址(quasi-colocation,QCL)信息,QCL假设,或QCL指示等。波束可以通过传输配置指示状态(transmission configuration indicator state,TCI-state)参数来指示,或者通过空间关系(spatial relation)参数来指示。
因此,本申请中,波束可以替换为空域滤波器,空间滤波器,空域参数,空间参数,空域设置,空间设置,QCL信息,QCL假设,QCL指示,TCI-state(包括上行TCI-state,下行TCI-state),或空间关系等。上述术语之间也相互等效。波束也可以替换为其他表示波束的术语,本申请在此不作限定。
用于发送信号的波束可以称为发送波束(transmission beam,Tx beam),空域发送滤波器(spatial domain transmission filter),空间发送滤波器(spatial transmission filter),空域发送参数(spatial domain transmission parameter),空间发送参数(spatial transmission parameter),空域发送设置(spatial domain transmission setting),或者空间发送设置(spatial transmission setting)。下行发送波束可以通过TCI-state来指示。
用于接收信号的波束可以称为接收波束(reception beam,Rx beam),空域接收滤波器(spatial domain reception filter),空间接收滤波器(spatial reception filter),空域接收参数(spatial domain reception parameter)或者空间接收参数(spatial reception parameter),空域接收设置(spatial domain reception setting),或者空间接收设置(spatial reception setting)。上行发送波束可以通过空间关系、上行TCI-state、探测参考信号(sounding reference signal,SRS)资源(表示使用该SRS的发送波束)中任一种来指示。因此,上行波束还可以替换为SRS资源。
发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布,接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
此外,波束可以是宽波束,或者窄波束,或者其他类型的波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术、混合数字波束赋形技术或者混合模拟波束赋形技术等。
波束一般和资源对应,例如进行波束测量时,网络设备通过不同的资源来测量不同的波束,终端设备反馈测得的资源质量,网络设备就知道对应的波束的质量。
当数据传输时,波束信息也是通过其对应的资源来进行指示的。例如,网络设备通过下行控制信息(downlink control information,DCI)中的传输配置指示(transmission configuration indicator,TCI)字段指示终端设备的物理下行共享信道(physical downlink shared channel,PDSCH)波束的信息。
可选的,将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或者多个天线端口,用于传输数据信道、控制信道和探测信号等。形成一个波束的一个或者多个天线端口也可以看作是一个天线端口集。
在本申请实施例中,若未做出特别说明,波束是指网络设备的发送波束。在波束测量中,网络设备的每一个波束对应一个资源,因此可以使用资源的索引来唯一标识该资源对应的波束。
3)本申请实施例中涉及的天线面板(panel),可以是网络设备的天线面板,也可以是终端设备的天线面板。
其中,一个天线面板上一般有一个或多个天线,这些天线组成天线阵列,进行波束赋形,从而形成模拟波束。该天线阵列可以生成指向不同方向的波束,但同一时间只能生成一个波束。也就是说每个天线面板上都可以形成多个波束,可以通过波束测量来确定该天线面板采用哪个波束是最好的。
终端设备可以配备多个天线面板,这些天线面板可以分布在不同的位置,朝向不同的方向,这可以保证无论终端设备朝向哪个方向,都至少有一个天线面板是朝向网络设备的,可以与网络设备进行数据传输。
例如图1所示,该终端设备配备了两个天线面板,每个天线面板朝向不同的方向,每个天线面板可以生成多个不同方向的波束,从而构成较为全面的波束覆盖,所述图1中以终端设备通过天线面板1生成波束1,通过天线面板2生成波束2为例进行描述。终端设备可以同时开启所有天线面板进行传输。或者,为了降低终端设备功耗,终端设备也可以一次采用单个天线面板进行传输,其他未使用的天线面板可以进行关闭。终端设备的天线面板处于打开还是关闭状态一般需要通知给网络设备。
在本申请实施例中,天线面板可以简称为面板,天线面板也可以用天线面板索引(panel index)等来表示。
除此之外,也可以通过其他方式来隐含表示天线面板,例如天线面板也可以通过天线端口(如CSI-RS端口,SRS端口,解调参考信号(demodulation reference signal,DMRS)端口,相位跟踪参考信号(phase tracking reference signal,PTRS)端口,CRS端口,时频跟踪参考信号(tracking reference signal,TRS)端口,SSB端口等)或天线端口组来表征,也可以通过资源(如CSI-RS资源,SRS资源,DMRS资源,PTRS资源,小区参考信号(cell reference signal,CRS)资源,TRS资源,SSB资源等)或资源组来表征,也可以通过某个信道表征(如PUCCH,PUSCH,物理随机接入信道(physical random access channel,PRACH),PDSCH,PDCCH,物理广播信道(physical broadcast channel,PBCH)等),也可以通过波束,QCL,TCI-state,spatial relation或配置在QCL,TCI-state,spatial relation中的某个索引来表征。也可以通过波束组,QCL组,TCI-state组,spatial relation组等来表征。也就是说,本申请中所述的天线面板/panel标识可以替换为上述内容的标识。
4)本申请实施例中“第一能力”(capability),指一个资源或资源组是否具有支持某一个特性(feature)或者特性集合(feature set)的能力。
其中,本申请实施例所述第一能力可以理解为终端设备采用某个资源或资源组对应的波束的情况下,所述终端传输能力,例如,所述终端设备采用该资源或资源组对应的波束的情况下,所述终端设备能传输的码字数,流数等,在此不进行限定。
5)本申请实施例中“第二能力”,指终端设备是否具有支持某一个特性(feature)或者特性集合(feature set)的能力。
其中,本申请实施例中所述第二能力可以理解为终端设备的传输能力,需要说明的是,本申请中所述第二能力所表示的终端设备的传输能力,是与波束无关的传输能力,即不强调在采用某个资源或资源组的情况下,终端设备具备的传输能力。
6)本申请实施例中“能力信息”,是一个能力包含的功能或特性的集合,也可以称为能力集或能力参数。

下面对本申请的应用背景进行简单介绍。
目前,在通信传输过程中,网络设备需要基于终端设备上报的终端能力信息进行调度,例如,网络设备可以基于终端设备上报的能够支持的传输流数,码字数等对终端设备进行调度。
其中,为了有效提高传输质量,在进行上下行数据传输时,网络设备和终端设备经常采用一个或一组波束进行上行传输,当采用一组波束时,该一组波束可以位于不同的天线面板(antenna panel)上,例如,通过多个panel上的各一个波束进行上行传输,各波束可以同时传输,也可以分时传输;该一组波束也可以位于同一个panel,此时该组波束中的各个波束只能进行分时传输。
然而,网络设备基于目前终端设备上报的终端能力信息,在上行传输调度中,无法根据终端设备采用的波束或波束组的传输能力进行针对性的上行传输调度,从而经常存在终端设备采用的上行传输波束
或波束组无法支持网络设备的传输调度,使得通信传输失败率较高。
基于此,本申请实施例提供了一种通信方法,通过本申请实施例提供的通信方法进行通信过程中,网络设备可以获取终端上报的一个或多个资源或资源组对应的传输能力信息,在后续采用该资源或资源组进行传输时,可以基于该资源或资源组的传输能力信息进行调度,从而有效避免调度的上行传输超出该资源或资源组的传输能力,导致传输失败的问题。
为便于理解本申请实施例,首先以图2中示出的通信系统为例详细说明本申请实施例适用的通信系统。如图2所示,该通信系统包括单个或多个网络设备210,和单个或多个终端设备220。
作为一种示例,当通信场景为单个网络设备向单个或多个终端设备传输数据或控制信令时,所述通信架构可以如图3所示,当通信场景为多个网络设备同时为单个终端设备传输数据或控制信令时,所述通信架构可以如图4所示。
其中,本申请实施例中涉及的网络设备,可以为无线网络中的设备。例如,网络设备可以是部署在无线接入网中为终端设备提供无线通信功能的设备。例如,网络设备可以为将终端设备接入到无线网络的无线接入网(radio access network,RAN)节点,又可以称为接入网设备。
网络设备包括但不限于:演进型节点B(evolved Node B,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),无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为5G移动通信系统中的网络设备。例如,NR系统中的下一代基站(next generation NodeB,gNB),传输接收点(transmission reception point,TRP),TP;或者,5G移动通信系统中的基站的一个或一组(包括多个天线面板)天线面板;或者,网络设备还可以为构成gNB或传输点的网络节点。例如,BBU,或,分布式单元(distributed unit,DU)等。
在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括有源天线单元(active antenna unit,AAU)。CU实现gNB的部分功能,DU实现gNB的部分功能。例如,CU负责处理非实时协议和服务,实现无线资源控制RRC,分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务,实现无线链路控制(radio link control,RLC)层、MAC层和物理(physical,PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来。因此在该架构下,高层信令(如RRC层信令)也可以认为是由DU发送的,或者,由DU和AAU发送的。可以理解的是,网络设备可以为包括CU节点、DU节点、AAU节点中一个或多个的设备。此外,可以将CU划分为RAN中的网络设备,也可以将CU划分为核心网(core network,CN)中的网络设备,本申请对此不做限定。
本申请实施例中涉及的终端设备,可以是能够接收网络设备调度和指示信息的无线终端设备。终端设备可以是指向用户提供语音和/或数据连通性的设备,或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。
终端设备,又称之为用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等。终端设备是包括无线通信功能(向用户提供语音/数据连通性)的设备。例如,具有无线连接功能的手持式设备、或车载设备等。目前,一些终端设备的举例为:手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、车联网中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。例如,车联网中的无线终端可以为车载设备、整车设备、车载模块、车辆等。工业控制中的无线终端可以为摄像头、机器人等。智慧家庭中的无线终端可以为电视、空调、扫地机、音箱、机顶盒等。
进一步地,本申请实施例所述的终端设备还可以上报与其天线架构相关的能力。
其中,终端设备采用两个panel进行同时传输时,两个panel对应的架构不同,能支持的传输模式也不同。
下面介绍两种架构:
架构1:两个panel连接独立的射频,独立的中频,独立的数字通道和独立的基带。即每个panel对应一套独立的射频+中频+数字通道+基带。
架构1下,终端设备可以支持的同传模式是最多的,例如可以支持采用两个panel传输不同码字,采用两个panel传输同一码字不同的流,采用两个panel进行频分传输,采用两个panel传输相同信号等。
具备架构1的终端设备可以上报第一终端能力给网络设备,网络设备收到该上报的第一终端能力后,就知道终端设备支持上述传输模式。
架构2:两个panel共享相同的基带和数字通道。两个panel对应的射频和中频模块可以是独立的,也可以是相同的。
架构2下,终端设备不能支持的部分传输模式,例如不支持采用两个panel传输不同码字,不支持采用两个panel传输同一码字不同的流,不支持两个panel采用独立的预编码进行传输,不支持两个panel采用不同的频域资源进行传输。
具备架构2的终端设备可以上报第二终端能力给网络设备,网络设备收到该上报的第二终端能力后,就知道终端设备支持上述传输模式。在这种情况下,网络设备不能为终端设备配置上述传输模式。
采用架构2的终端设备也可以通过一些特殊的方法来实现两个panel采用独立的预编码进行传输。例如,通过对第二个panel对应的相移器进行相位偏移,来等效实现独立的预编码功能。
具体地,假设网络设备为终端设备指示了两个预编码矩阵,终端设备的基带采用第一个预编码。如果不做任何特殊处理,最终两个panel都采用该预编码,因为两个panel是共享基带的。
为了第二个panel能采用独立的预编码,可以将第二个panel上与各个数字通道(数字端口port)连接的那组相移器进行整体相移,从而等效实现对各个数字通道上的信号进行改变,从而等效于改变了预编码矩阵。
例如图5所示,假设网络设备给终端设备指示了两个预编码矩阵和终端设备在基带采用这样两个panel对应的预编码矩阵都是为了能让第二个panel等效地采用预编码矩阵可以将第二个panel上与第二个数字通道(port 2)相连的那些相移器整体进行pi/2的相位偏移,从而等效于将port2上的信号乘以j,从而等效于将转变成了
通过上述方法,虽然两个panel采用同一基带和数字端口,但也可以等效实现独立的预编码。
上述特殊处理也是有能力要求的,具备上述特殊处理能力的终端设备可以上报第三能力给终端设备,表示其具备上述能力。采用上述处理方式实现等效的独立预编码是有一定限制的,例如通过上述方法实现的第二个panel的预编码是全带的,即第二个panel在不同频率上不能采用不同的预编码。
因此,对于上报第三能力的终端设备,网络设备需要确保其为终端设备指示的第二个预编码矩阵是全带同一的。当网络设备调度终端设备在多组频率资源上进行上行传输时,为终端设备指示的第二预编码在上述多组频域资源上是相同的。例如,网络设备调度终端设备进行上行多载波传输,即在多个载波频率上进行上行传输时,多个载波上的传输所采用的第二预编码矩阵是相同的。
此外,对于上报第三能力的终端设备,网络设备需要确保其为终端设备指示的第二个预编码矩阵是可以通过第一个预编码矩阵导出的。也就是说,第二个预编码矩阵的任意一行可以通过对第一个预编码矩阵的同一行乘以一个常数来得到(第i行可以是任意一行),该常数可以是1,-1,j,-j。换句话说,第二个预编码矩阵的选择是受限的,网络设备根据第一个预编码矩阵来决定第二个预编码矩阵的可选区范围。上述限制可以在采用rank 2或更高rank的码本时才采用,采用rank 1的码本可以不需要满足上述限制。
采用架构2的终端设备也可以通过一些特殊的方法来实现两个panel采用不同频率资源进行传输。例如,如图6所示,在第二个panel对应的信号上进行频率搬移,从而实现第一个和第二个panel采用不同的频率进行传输。可以在第二个panel对应的模拟信号上进行频率搬移,也可以在时域数字信号上进行频率搬移。上述特殊处理也是有能力要求的,具备上述特殊处理能力的终端设备可以上报第四能力给终端设备,表示其具备上述能力。
采用上述处理方式实现两个panel采用不同频率进行传输是有一定限制的,例如由于是对信号进行频率搬移,两个panel采用不同频率传输的实质是相同信号。因此通过上述方式实现的两panel频分传输只能用于传输相同信号,而不能传输不同信号。
因此,在终端设备上报其支持第四能力的情况下,除了采用两个panel传输相同信号的传输模式外,网络设备不能为其配置其他频分传输模式,例如两个panel采用不同频率传输不同RV(redundancy version,冗余版本)等。此外,在终端设备上报其支持第四能力的情况下,如果网络设备指示终端设备采用频分传输,那么不能指示终端设备进行多CC同时传输,否则进行频域搬移后会造成CC间干扰。

其中,所述网络设备可以将获取到的资源或资源组的传输能力信息存储到自身的存储空间中,也可以将获取到的资源或资源组的传输能力信息存储到第三方存储平台中。

输调度信息的准确性,所述网络设备可以直接基于接收到的所述第一能力信息确定所述上行传输调度信息,以及所述网络设备还可以根据所述第一能力信息对已存储的资源或资源组级的传输能力信息进行更新。
