应当理解,尽管在本申请可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本申请范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,例如,在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
需要说明的是,本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号,均为经用户授权或者经过各方充分授权的,且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
首先对本申请实施例提供的若干个术语进行简介。
基向量:该基向量包括空域基向量和频域基向量。该空域基向量可以理解为波束,而频域基向量可以理解为包括各个频域单元对应的相位的向量。
在一些实施例中,网络设备可以为终端提供服务,并且网络设备可以为终端配置CSI(Channel State Information,信道状态信息)测量配置,终端可以基于CSI测量配置进行CSI测量,向网络设备上报得到的CSI报告。其中CSI报告中包括基向量的信息。例如,CSI包括中包括空域基向量信息和频域基向量信息中的至少一项。
可选地,该CSI报告中包含预编码矩阵(Precoding Matrix Indicator,PMI)上报,而PMI包含空域基向量和频域基向量中的至少一项的选择。
下面,对本申请的应用场景进行说明:
图1示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:终端10和网络设备20。
终端10的数量通常为多个,每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE)、移动台(Mobile Station,MS)等等。为方便描述,本申请实施例中,上面提到的设备统称为终端。
网络设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述,本申请实施例中,上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接,从而通过该连接进行通信,包括信令和数据的交互。网络设备20的数量可以有多个,两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行数据传输,也即与不同的网络设备20建立连接。
该网络设备20可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的系统中,具备网络设备功能的设备的名称可能会有所不同,例如在5G NR(New Radio,新空口)系统中,称为gNodeB或者gNB。随着通信技术的演进,“网络设备”这一名称可能会变化。
可选地,网络设备20上设置有至少两个TRP(Transmission Reception Point, 传输接收节点);或者至少两个网络设备20,每个网络设备20上设置至少一个TRP,即至少两个网络设备20设置有至少两个TRP。也就是说,至少两个TRP可以来自同一个小区或不同的小区。
在一些实施例中,参见图2,网络设备20上设置4个TRP,并且可以通过4个TRP为终端10提供服务,并且终端10需要针对4个TRP进行CSI测量上报。
可选地,本申请实施例中的TRP实际上可以通过CMR指示,也就是说一个CMR(Channel Measurement Resource,信道测量资源)指示一个TRP。若网络设备20配置了4个TRP,则采用4个CMR分别指示这4个TRP。
需要说明的是,本申请实施例仅是以TRP为例进行说明。而在另一实施例中,TRP还可以称为是RRH(Remote Radio Head,射频拉远头),也就是说本申请实施例中的CMR对应RRH。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统,但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统,也可以适用于5G NR系统后续的演进系统。
图3示出了本申请一个示例性实施例提供的参数指示方法的流程图,示例性的可以应用于如图1所示的终端和网络设备中,该方法包括以下内容中的至少部分内容:
步骤301:终端向网络设备发送指示信息,指示信息用于指示多个CMR的基向量参数信息是否相同。
步骤302:网络设备接收终端发送的指示信息,指示信息用于指示多个CMR的基向量参数信息是否相同。
在本申请实施例中,网络设备与终端之间会进行通信,网络设备会为终端配置信道测量资源集,终端会根据配置的信道测量资源集进行测量,并向网络设备上报选择的基向量参数信息。
而网络设备为终端配置多个CMR,以便于终端针对多个CMR中的每个CMR确定选择的基向量参数信息,并且终端确定的每个CMR的基向量参数信息可能相同,也可能不同,因此终端可以向网络设备发送用于指示多个CMR的基向量参数信息是否相同的指示信息,网络设备接收到终端发送的指示信息后,即可确定多个CMR的基向量参数信息是否相同。
在一些实施例中,多个CMR中的每个CMR对应一个TRP,也就是多个CMR与多个TRP一一对应。换一种表达方式,网络设备可以通过多个TRP为终端提供服务。
例如,若多个CMR为4个,则可以理解为网络设备与终端之间设置4个TRP,通过4个TRP进行数据传输。而对于终端来说,终端需要针对4个TRP中的每个TRP上报选择的基向量参数信息。
可选地,多个CMR为不同的NZP CSI-RS(Non-Zero Power Channel State Information Reference Signal,非零功率信道状态信息参考信号)资源,或者,多个CMR为同一个NZP CSI-RS资源的不同端口组,端口组包括一个或多个端口。本公开实施例中,可以是所有的CMR中的部分CMR为不同的NZP CSI-RS资源,或者,所有的CMR中的部分CMR为同一个NZP CSI-RS资源的不同端口组,其中该端口组包括一个或多个端口。当然,还可以是所有的CMR中都为不同的NZP CSI-RS资源,或者,所有的CMR为同一个NZP CSI-RS资源的不同端口组,其中该端口组包括一个或多个端口。
在本申请实施例中,一个CMR包括NZP CSI-RS资源,并且不同的CMR包括的CSI-RS资源不同。其中,一个CMR对应一个TRP,则本申请实施例中的不同的NZP CSI-RS资源即可理解为对应不同的TRP。
例如,本申请实施例涉及4个CMR,分别为CMR1、CMR2、CMR3和CMR4,而CMR1包括NZP CSI-RS资源1,CMR2包括NZP CSI-RS资源2,CMR3包括NZP CSI-RS资源3,CMR4包括NZP CSI-RS资源4。
又或者,不同CMR包括同一个NZP CSI-RS资源的不同端口组,多个CMR包括的所有端口组属于同一个NZP CSI-RS资源。其中,一个端口组包括至少一个端口。其中,一个CMR对应一个TRP,则本申请实施例中不同的端口组可以理解为对应不同的TRP。
例如,本申请实施例涉及4个CMR,分别为CMR1、CMR2、CMR3和CMR4,而一个NZP CSI RS资源包括32个端口,分成4个端口组,每个端口组包含8个端口,而CMR1包括端口组1,CMR2包括端口组2,CMR3包括端口组3,CMR4包括端口组4。
在一些实施例中,基向量参数信息包括以下至少一项:
(1)空域基向量的数量。
其中,该空域基向量的数量是指终端针对每个或多个CMR上报的空域基向 量的数量。在一些实施例中,该空域基向量可以理解为波束,也就说是空域基向量的数量实际上是指终端选择的波束的数量。
(2)空域基向量的标识。
其中,该空域基向量的标识用于指示空域基向量。在一些实施例中,该空域基向量可以理解为波束,也就是说空域基向量的标识实际上是指终端选择的波束的标识,用来指示波束。在一些实施例中,可以直接反馈多个空域基向量的组合标识。
(3)频域基向量的数量。
其中,该频域基向量的数量是指终端针对每个或多个CMR上报的频域基向量的数量。在一些实施例中,该频域基向量可以理解为包括各个频域单元对应的相位的向量,也就说是频域基向量的数量实际上是指终端选择的向量的数量。
(4)频域基向量的标识。
其中,该频域基向量的标识用于指示频域基向量。在一些实施例中,该频域基向量可以理解为包括各个频域单元对应的相位的向量,也就是说频域基向量的标识实际上是指终端选择的向量的标识。在一些实施例中,可以直接反馈多个频域基向量的组合标识。
(5)频域基向量窗口的起始位置。
在本申请实施例中,频域基向量窗口具有一定的窗口长度,终端可以基于选择的频域基向量确定该频域基向量的窗口的起始位置,以便于告知网络设备。
可选地,频域基向量的窗口长度由网络设备配置,或者由通信协议约定,或者采用其他方式配置,本申请实施例不做限定。
需要说明的是,本申请实施例中的指示信息承载在CSI报告中。其中,网络设备可以为终端配置CMR,则终端确定网络设备配置的CMR后,即可基于被配置的CMR进行CSI测量,得到CSI报告,该CSI报告中包括终端确定的指示信息,进而通过向网络设备发送携带指示信息的CSI报告,而网络设备接收到该CSI报告后,即可确定多个CMR的基向量参数信息是否相同。
在一些实施例中,终端基于被配置的CMR进行CSI测量,即可确定每个CMR的基向量参数信息,进而根据多个CMR中每个CMR的基向量参数信息确定多个CMR的基向量参数信息是否相同,以便于通过CSI报告向网络设备指示多个CMR的基向量参数信息是否相同。
在一些实施例中,该CSI报告包括第一信息域和第二信息域,该第一信息 域包括指示信息,该第二信息域包括基向量参数信息。
可选地,该第一信息域不仅包括指示信息,还包括CRI(CSI-RS Resource Indicator,CSI-RS资源指示)、Rank(秩)指示等信息。该第二信息域包括PMI,基向量参数信息承载在PMI中。
需要说明的是,本申请实施例中终端所执行的步骤可以单独形成一个新的实施例,网络设备所执行的步骤也可以单独形成一个新的实施例,本申请不做限定。
本申请提供了一种终端指示多个CMR中是否存在共用基向量参数的方案,保证后续终端上报的基向量参数信息由多个CMR共用,节省上报开销,进而节省传输资源。
图3所示实施例对终端可以发送指示多个CMR的基向量参数信息是否相同的指示信息进行说明。而终端在确定指示信息指示CMR的基向量参数信息相同的情况下,还会向网络设备发送CMR共用的基向量参数信息。图4示出了本申请一个示例性实施例提供的参数指示方法的流程图,示例性的可以应用于如图1所示的终端和网络设备中,该方法包括以下内容中的至少部分内容:
步骤401:终端在指示信息指示至少两个CMR的基向量参数信息相同的情况下,向网络设备发送第一基向量参数信息,至少两个CMR共用第一基向量参数信息。
步骤402:网络设备接收终端发送的第一基向量参数信息,其中该第一基向量参数信息由终端在指示信息指示至少两个CMR的基向量参数信息相同的情况下发送,至少两个CMR共用第一基向量参数信息。
在本申请实施例中,若存在至少两个CMR的基向量参数信息相同,则终端会通过指示信息来指示至少两个CMR的基向量参数信息存在相同的情况,并且终端还会向网络设备上报至少两个CMR共用的第一基向量参数信息,则网络设备接收该第一基向量参数信息后,即可确定终端的至少两个CMR的基向量参数信息。
在一些实施例中,终端向网络设备发送至少两个CMR中第一个CMR的第一基向量参数信息,至少两个CMR中除第一个CMR以外的其他CMR的基向量参数信息与第一基向量参数信息相同。也就是说,终端上报至少两个CMR中第一个CMR的第一基向量参数信息后,至少两个CMR中除第一个CMR以外 的其他CRM的基向量参数信息均复用第一个CMR的第一基向量参数信息。
在本申请实施例中,对于网络设备来说,网络设备会接收终端发送的至少两个CMR中第一个CMR的第一基向量参数信息,并且至少两个CMR中除第一个CMR以外的其他CMR的基向量参数信息与第一基向量参数信息相同。
例如,至少两个CMR包括CMR1、CMR2、CMR3和CMR4,并且指示信息指示了至少两个CMR的基向量参数信息相同,也就是说CMR1、CMR2、CMR3和CMR4的基向量参数信息相同。则终端向网络设备发送CMR1、CMR2、CMR3和CMR4中属于第一个的CMR1的第一基向量参数信息,而CMR2、CMR3和CMR4的基向量参数信息与CMR1的第一基向量参数信息相同。
本申请实施例中,若指示信息指示至少两个CMR的基向量参数信息相同,则终端向网络设备上报至少两个CMR中第一个CMR的第一基向量参数信息,而其他CMR的基向量参数信息复用第一个CMR的第一基向量参数信息。
需要说明的是,本申请实施例中基向量参数信息可以包括不同的参数,而不同CMR的基向量参数信息相同是指不同CMR的基向量参数信息包括的所有参数均相同。
其中,该基向量参数信息包括空域基向量的数量、空域基向量的标识、频域基向量的数量、频域基向量的标识、频域基向量窗口的起始位置中的至少一项,因此在不同CMR的基向量参数信息包括的参数均相同的情况下,确定不同CMR的基向量参数信息相同。
例如,若基向量参数信息包括空域基向量的数量、空域基向量的标识、频域基向量的数量、频域基向量的标识,则至少两个CMR的基向量参数信息相同是指基向量参数信息包括的空域基向量的数量、空域基向量的标识、频域基向量的数量、频域基向量的标识均相同。又例如,若基向量参数信息包括空域基向量的数量、频域基向量的数量和频域基向量窗口的起始位置,则至少两个CMR的基向量参数信息相同是指空域基向量的数量、频域基向量的数量和频域基向量窗口的起始位置均相同。本申请还可以包括其他情况,在此不再一一举例说明。
在一些实施例中,多个CMR的基向量参数信息中可能存在部分CMR的基向量参数信息相同,也可能存在全部CMR的基向量参数信息相同,而对于不同情况终端向网络设备上报的参数也不同,下面对每种上报情况进行说明。
第一种:在至少两个CMR为多个CMR的全部CMR的情况下,向网络设 备发送多个CMR中第一个CMR的第一基向量参数信息。
在本申请实施例中,若指示信息指示的至少两个CMR是属于多个CMR中的全部CMR的情况,则终端直接向网络设备发送多个CMR中第一个CMR的第一基向量参数信息即可,而对于网络设备来说,网络设备实际上是在确定指示信息指示的是多个CMR中的全部CMR的基向量参数信息均相同时,默认多个CMR中除第一个CMR以外的其他CMR均与第一个CMR的第一基向量参数信息相同。
换一种表达方式,在终端确定多个CMR中全部的CMR的基向量参数信息均相同时,采用指示信息指示多个CMR的基向量参数相同,则终端只需发送一个基向量参数信息,网络设备接收到该指示信息和基向量参数信息后,即可确定多个CMR中所有的CMR均使用相同的一个基向量参数信息。
例如,至少两个CMR包括CMR1、CMR2、CMR3和CMR4,并且指示信息指示了至少两个CMR的基向量参数信息相同,也就是说CMR1、CMR2、CMR3和CMR4的基向量参数信息相同。则终端向网络设备发送CMR1、CMR2、CMR3和CMR4中属于第一个的CMR1的第一基向量参数信息,而CMR2、CMR3和CMR4的基向量参数信息与CMR1的第一基向量参数信息相同。
第二种:在至少两个CMR为多个CMR的部分CMR的情况下,向网络设备发送至少两个CMR中第一个CMR的第一基向量参数信息,且指示信息还用于指示第一个CMR的标识信息。
在本申请实施例中,若指示信息指示的至少两个CMR是属于多个CMR中的部分CMR的情况,则终端不仅需要向网络设备发送多个CMR中第一个CMR的第一基向量参数信息,还需要向网络设备发送用于指示第一个CMR的标识信息,以便于至少两个CMR中除第一个CMR的其他CMR确定对应的基向量参数信息与哪个CMR的基向量参数信息相同。
而对于网络设备来说,网络设备实际上是在确定指示信息指示的是多个CMR中的全部CMR的基向量参数信息均相同的时,默认多个CMR中除第一个CMR以外的其他CMR均与第一个CMR的第一基向量参数信息相同。
换一种表达方式,终端在确定多个CMR中部分CMR的基向量参数信息相同时,即可向网络设备发送指示信息,但是由于并不是所有的CMR的基向量参数信息均相同,因此需要通过发送CMR的标识信息,来指示其他CMR的基向量参数信息使用哪个标识信息指示的CMR的基向量参数信息。
例如,多个CMR包括CMR1、CMR2、CMR3和CMR4,而至少两个CMR分别为CMR2、CMR3和CMR4,则终端需要向网络设备发送CMR2的基向量参数信息,并且分别针对CMR3和CMR4发送标识信息指示CMR2的标识,该CMR2的标识信息用于告知网络设备CMR3和CMR4使用CMR2的基向量参数信息。也就是说CMR2、CMR3和CMR4的基向量参数信息相同。
在一些实施例中,多个CMR中包括至少一组CMR组,每组CMR组包括至少两个CMR,在此情况下,终端分别向网络设备发送每个CMR组中第一个CMR的基向量参数信息,并且对于每个CMR组,还会发送每个CMR组中第一个CMR的标识信息,以便于每个CMR组中除第一个CMR以外的其他CMR的基向量信息使用与第一个CMR相同的基向量参数信息。
例如,多个CMR包括CMR1、CMR2、CMR3和CMR4,而CMR1和CMR2的基向量参数信息相同,CMR3和CMR4的基向量参数信息相同,则终端需要向网络设备发送CMR1的基向量参数信息和CMR3的基向量参数信息,并且还会向网络设备发送针对CMR2的CMR1的标识信息和针对CMR4的CMR3的标识信息,以便于告知网络设备CMR2的基向量参数信息复用CMR1的基向量参数信息,CMR4的基向量参数信息复用CMR3的基向量参数信息。
本申请实施例提供的方案中,终端在至少两个CMR基向量参数信息不同情况时上报不同的参数,以便于向网络设备上报多个CMR的基向量参数信息,在扩展上报CMR的基向量参数信息的方式的基础上,提高了TRP的传输性能,并且节省了信令开销。
需要说明的是,本申请实施例是以终端通过上报至少两个CMR中的第一个CMR的基向量参数信息为例进行说明。而在另一实施例中,终端还可以上报基向量参数信息以及该基向量参数信息对应的CMR组,该CMR组中包括至少一个CMR。
在本申请实施例中,由于存在至少两个CMR的基向量参数信息相同的情况,因此终端可以通过向网络设备上报基向量参数信息与CMR组的对应关系,以便于网络设备在接收到该对应关系时,即可确定每个CMR的基向量参数信息。
在一些实施例中,每个CMR组包括CMR的标识信息,通过该CMR标识信息指示CMR。
例如,多个CMR包括CMR1、CMR2、CMR3和CMR4,若CMR1和CMR2的基向量参数信息相同,CMR3和CMR4的基向量参数信息相同,则终端向网 络设备发送第二基向量参数信息,该第二基向量参数信息对应CMR1和CMR2,并且终端还向网络设备发送第三基向量参数信息,该第三基向量参数信息对应CMR3和CMR4。
图3所示实施例对终端可以发送指示多个CMR的基向量参数信息是否相同进行说明。而在指示信息指示多个CMR的基向量参数信息不同的情况下,终端会分别上报每个CMR的基向量参数信息。图5示出了本申请一个示例性实施例提供的参数指示方法的流程图,示例性的可以应用于如图1所示的终端和网络设备中,该方法包括以下内容中的至少部分内容:
步骤501:终端在指示信息指示多个CMR的基向量参数信息不同的情况下,向网络设备分别发送多个CMR中每个CMR的基向量参数信息。
步骤502:网络设备接收终端分别发送的多个CMR中每个CMR的基向量参数信息;多个CMR中每个CMR的基向量参数信息由终端在指示信息指示多个CMR的基向量参数信息不同的情况下发送。
在本申请实施例中,终端若确定多个CMR的基向量参数信息均不相同,则终端需要通过指示信息指示多个CMR的基向量参数信息不同,也就是说多个CMR中每个CMR的基向量参数均不相同,并且终端需要单独向网络设备发送每个CMR的基向量参数信息,以便于网络设备分别确定每个CMR的基向量参数信息。
本申请实施例提供的方案中,终端若确定多个CMR的基向量参数信息不同,则会通过指示信息指示多个CMR的基向量参数信息均不同,并且还会分别上报每个CMR的基向量参数信息,保证每个CMR对应的TRP的传输性能,进而保留了通信的可靠性。
需要说明的是,上述实施例可以拆分为新实施例,或与其他实施例互相组合为新实施例,本申请对实施例之间的组合不做限定。
