Description

一种用于转发器的波束指示方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
与传统的3G(第三代移动通信技术)、4G(第四代移动通信技术)系统相比，5G(第五代移动通信技术)系统能够提供更大的带宽以及更高的数据率，并且能够支持更多类型的终端和垂直行业业务。为此，5G系统的现有部署频率通常高于3G和4G系统。例如，5G系统可以部署在毫米波波段。
然而，承载频率越高，信号在传输过程中经历的衰落越严重。因此，在5G系统的实际部署中，特别是在毫米波段，如何更好的增强小区覆盖，成为亟待解决的问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
为了更好的解决蜂窝移动通信系统在实际部署中的覆盖问题，采用射频转发器(RF Repeater)放大和转发终端与基站之间的通信信号，是比较常用的部署手段。射频转发器在3G系统和4G系统的实际部署中具有较为广泛的应用。通常来说，传统射频转发器是一种在射频域放大和转发基站与终端往来信号的设备。传统射频转发器在转发过程中，不对转发信号进行解调解码。传统射频转发器的天线方向通常是固定的。传统射频转发器的天线方向通常在初始安装的时候人工进行设置和调整，以使得基站侧的天线指向基站来波方向，终端侧的天线指向需要增强部署的地方。在传统射频转发器工作的过程中，天线方向不发生改变。此外，传统射频转发器不具备通信功能，不能够和基站进行信息交互，因此也不支持基站对其进行自适应和/或较为动态的配置。
相比于3G和4G系统，部署在较高频段和毫米波频段的5G系统采用了更为高级和复杂的MIMO(多进多出)技术。在5G系统中，有向天线成为基站与终端设备 的基本部件，基于波束赋形(Beam forming)技术发送和接收信号是5G系统中基本的信号传输方式。特别是毫米波波段频率高、小波长的特点更利于在基站和终端设备中设置包含较多阵子的天线面板。天线阵子个数的增加有助于更为精准的波束赋形，即更容易形成窄波束。窄波束汇聚能量有助于增强信号，并同时减小对其它设备的干扰。另一方面，由于窄波束的指向精准，对信道测量和波束管理的要求非常高，因此5G系统支持较为复杂但精准的信道测量、天线校准和波束管理方案，基站可以通过这些方案有效而精准的控制终端设备的接收波束和发送波束，以达到更好的通信效果。
发明人发现，针对5G系统在部署中遇到的覆盖问题，采用射频转发器进行覆盖增强是可行的解决方案之一。但是，传统射频转发器的天线不可动态调整方向、波束较宽。这样的射频转发器配置在5G系统中，虽然能够帮助增强信号强度，但也会由于发送波束较宽对周围的其它基站或者终端设备造成比较明显的干扰，进而因为新干扰的增加而降低整个网络的吞吐量。
在3GPP(第三代合作伙伴计划)Release18(版本18)的讨论中，一种新型Repeater设备被构想。在该设备构想中，Repeater能够与gNB进行通信。gNB能够对Repeater进行一定程度的配置，并通过这些配置优化Repeater的转发性能以及减小对周围其它设备的干扰等。
本申请实施例提供了一种用于转发器的波束指示方法、装置和系统。网络设备(gNB)可以配置转发器(Repeater)所使用的波束，从而更精准的管理转发器的转发、实现更好的覆盖、减小对周围其它设备的干扰并由此提高整个网络的传输效率。
根据本申请实施例的一方面，提供一种用于转发器的波束指示装置，配置于网络设备，其中，所述装置包括：
发送单元，其向转发器发送第一指示，所述第一指示用于指示至少一个波束。
根据本申请实施例的另一方面，提供一种波束确定装置，配置于转发器，其中，所述装置包括：
接收单元，其接收网络设备发送的第一指示，所述第一指示用于指示至少一个波束。
本申请实施例的有益效果之一在于：网络设备可以配置转发器所使用的波束，从而更精准的管理转发器的传输、实现更好的覆盖、减小对周围其它设备的干扰并由此提高整个网络的传输效率。

第一方面的实施例
本申请实施例提供一种用于转发器的波束指示方法，从网络设备侧进行说明。
图2是本申请实施例的用于转发器的波束指示方法的一示意图，请参照图2，该 方法包括：
201：网络设备向转发器发送第一指示，所述第一指示用于指示至少一个波束。
根据本申请实施例，网络设备可以配置转发器所使用的波束，从而更精准的管理转发器的传输、实现更好的覆盖、减小对周围其它设备的干扰并由此提高整个网络的传输效率。
在本申请实施例中，波束(beam)也可以表述为波瓣(beam)、参考信号(RS)、传输配置指示(TCI，transmission configuration indication)、空域滤波器(spatial domain filter)等，或者，也可以表述为波束索引、波瓣索引、参考信号索引、传输配置指示索引、空域滤波器索引等。上述参考信号例如为CSI-RS、SRS、供转发器使用的RS、由转发器发送的RS等。上述TCI也可以表述为TCI状态(state)。
在本申请实施例中，上述至少一个波束用于转发器对网络设备和终端设备之间的信号进行转发。
例如，所述至少一个波束中的一个波束是：用于所述转发器向终端设备转发来自所述网络设备的第一信号的第一波束。如图3所示，转发器302使用第一波束向终端设备303发送第一信号，该第一信号来自于网络设备301，例如来自于网络设备301发出的第四信号。
再例如，所述至少一个波束中的一个波束是：用于所述转发器接收来自所述网络设备的第四信号的第四波束，所述第四信号用于转发给所述终端设备。如图3所示，转发器302使用第四波束接收第四信号，该第四信号是网络设备301发出的信号。
在上述例子中，第四信号包含网络设备向终端设备发送的信号，转发器不对该第四信号中的网络设备向终端设备发送的信号进行解调和/或解码。
其中，网络设备向终端设备发送的信号包括信令、数据以及参考信号的其中至少之一。
其中，第四信号除了包含网络设备向终端设备发送的信号以外，还可以包含网络设备向转发器发送的信号，转发器对第四信号中包含的给自己的信号进行解调和/或解码，不对第四信号中包含的网络设备向终端设备发送的信号进行解调和/或解码。
在上述例子中，来自网络设备的第一信号可以由转发器至少通过对其接收到的第四信号进行放大生成。
再例如，所述至少一个波束中的一个波束是：用于所述转发器接收来自所述终端 设备的第二信号的第二波束，所述第二信号用于转发给所述网络设备。如图4所示，转发器402使用第二波束接收第二信号，该第二信号是终端设备403发出的信号。
再例如，所述至少一个波束中的一个波束是：用于所述转发器向所述网络设备转发来自所述终端设备的第三信号的第三波束。如图4所示，转发器402使用第三波束向网络设备401发送第三信号，该第三信号是来自于终端设备403，例如来自于终端设备发出的第二信号。
在上述例子中，第二信号包含终端设备向网络设备发送的信号，转发器不对终端设备向网络设备发送的信号进行解调和/或解码。
其中，终端设备向网络设备发送的信号包括信令、数据以及参考信号的其中至少之一。
在上述例子中，来自终端设备的第三信号可以由转发器至少通过对其收到的第二信号进行放大生成。
再例如，所述至少一个波束中的一个波束是：用于所述转发器向所述网络设备发送第五信号的第五波束。如图5所示，转发器502使用第五波束向网络设备501发送第五信号。
再例如，所述至少一个波束中的一个波束是：用于所述转发器接收来自所述网络设备的第六信号的第六波束。如图6所示，转发器602使用第六波束接收第六信号，该第六信号是网络设备601发出的信号。
在本申请实施例中，网络设备可以是终端设备的服务小区的网络设备，也可以是转发器所在的小区的网络设备，还可以是转发器的服务小区的网络设备，也可以是转发器的父节点(Parent node)，本申请对该转发器的名称不做限制，只要能实现上述功能的设备，都包含于本申请的转发器的范围内。
在本申请实施例中，第一指示可以由第一PDSCH(物理下行共享信道)承载。
在上述实施例中，网络设备还可以向转发器发送第二指示，该第二指示用于指示转发器使用第七波束接收该第一PDSCH，进而得到上述第一指示，根据该第一指示进行上述处理。
在上述实施例中，该第一指示可以是MAC(媒体接入控制)层信令，也可以是RRC(无线资源控制)信令，本申请不限于此。
在本申请实施例中，第一指示也可以由第一PDCCH(物理下行控制信道)进行 指示。
在上述实施例中，网络设备还可以向转发器发送第三指示，该第三指示用于指示转发器使用第八波束接收该第一PDCCH，进而得到上述第一指示，根据该第一指示进行上述处理。
在上述实施例中，上述第一PDCCH还用于指示所述转发器使用第九波束接收所述网络设备发送给所述转发器的第二PDSCH，或者，所述第一PDCCH还用于指示所述转发器使用第十波束向所述网络设备发送第二PUSCH。关于该第一PDCCH的相关内容，可以参考相关技术，此处省略说明。
根据本申请实施例，网络设备利用PDCCH信道对第一指示进行指示可以更加快速、准确的调整转发器的上述第一波束至第六波束，从而有效提高转发器所使用波束的精确程度，提高传输效率、减少空间干扰。
此外，重用用于调度转发器的PDSCH传输或者PUSCH传输的PDCCH去指示上述第一至第四波束，可以减小控制信令开销，进而提高时频资源利用率，提高网络的传输效率。
在本申请实施例中，网络设备也可以利用高层信令(例如MAC或者RRC信令等)或者利用高层信令结合PDCCH对第一指示进行半静态指示。网络设备还可以利用高层信令(例如MAC或者RRC信令等)或者利用高层信令结合PDCCH在第一指示中一次性指示多个波束。在一些情况下，为转发器半静态配置或者一次配置多个第一至第四波束(或者第一至第六波束)有助于提高转发器的转发效率等。
值得注意的是，传统射频转发器的天线方向通常是固定的。在初始安装后转发器在终端侧使用一个较宽的波束覆盖其预定覆盖的区域，之后不再进行调整，或者在有需要的情况下需要进行人工调整。网络设备不能够对转发器的转发波束进行配置。
根据本申请实施例，网络设备能够针对转发器的发送波束、接收波束以及转发波束进行配置，从而可以采用精准的波束管理方案控制转发器的转发。被精准管理的波束通常赋形较好，能够更准确地指向需要被服务的终端设备。但是，赋形较好的波束通常比较窄，很难通过一个赋形较好的波束覆盖整个转发器需要覆盖的区域。因此，为了服务转发器覆盖范围内处于不同地理位置的终端设备，转发器需要在不同时间采用不同指向的波束以便服务不同终端设备。
在一些情况下，转发器需要在不同时间内与网络设备进行通信和对网络设备与终 端设备之间交互的信号进行转发。转发器与网络设备之间的通信可能会打断转发器的转发。这种情况下，网络设备可以在一次配置中指示在较长一段时间内转发器如何使转发波束，从而减少转发器与网络设备之间的通信，提高转发效率从而提高网络的整体传输效率。
在另一些情况下，当转发器服务的终端设备移动性不明显的时候，网络设备也可以在一次配置中指示在较长一段时间内转发器如何使转发波束，借此提高转发效率从而提高网络的整体传输效率。
下面介绍网络设备为转发器配置多个上述第一波束至第四波束的例子。
在本申请实施例中，上述第一波束至第四波束中的至少一个波束与第一时间段相关，该第一时间段用于转发器在该第一时间段的至少部分时间内，使用上述第一波束至第四波束中的至少一个波束，对网络设备和终端设备之间的信号进行转发。
在上述实施例中，第一时间段可以由至少一个时间单位组成。该时间单位可以是符号、时隙(slot)、子帧、小时隙(mini-slot)、基于非时隙调度(non-slot-based scheduling)对应的最小调度时间单位、帧等等。
在上述实施例中，第一时间段可以由上述第一指示进行指示，也可以由第四指示进行指示，还可以由第一指示和第四指示进行联合指示，还可以是由标准预定义并在出厂前预设在转发器中。
例如，通过第一指示来指示第一时间段的长度和起始点；或者，通过第四指示来指示第一时间段的长度和起始点；或者，通过第一指示来指示第一时间段的长度，通过第四指示来指示第一时间段的起始点；或者，通过第一指示来指示第一时间段的起始点，而通过第四指示来指示第一时间段的长度，等等。
再例如，通过第四指示来指示上述第一波束至第四波束中的至少一个波束与第一时间段的多种组合，再通过第一指示用于指示其中一种合或者多种组合，这里，第一指示可以通过索引等进行指示，或者通过位图(bitmap)等方式进行指示。
在上述实施例中，第四指示是网络设备发送给转发器的，其可以由第三PDSCH承载，也可以由第三PDCCH指示。
在上述实施例中，对于所述第一时间段内不对应所述第一波束至第四波束中的至少一个波束的时间，也即，上述第一波束至第四波束中的至少一个波束在所述第一时间段的使用时间的总和以外的时间，转发器不对网络设备和终端设备之间的信号进行 转发。
图7至图12示出了网络设备为转发器配置多个上述第一波束至第四波束的例子。
图7是网络设备配置转发器在第一时间段的全部时间内使用波束A和波束B对网络设备和终端设备之间的信号进行转发的示意图。波束A和波束B的作用不同，例如波束A为第一波束而波束B为第二波束，波束A为第三波束而波束B为第四波束，等等。关于转发器的行为已经在前面做了详细说明，此处省略说明。
图8是网络设备配置转发器在第一时间段的部分时间内使用波束A和波束B对网络设备和终端设备之间的信号进行转发的示意图。波束A和波束B的作用不同，例如波束A为第一波束而波束B为第二波束，波束A为第三波束而波束B为第四波束，等等。
图9和图10示出了网络设备配置转发器在该第一时间段的部分时间内，使用五个波束(称为波束A、波束B、波束C、波束D、波束E)对网络设备和终端设备之间的信号进行转发的情况。该五个波束作用相同，即为第一波束至第四波束中的一种。该五个波束空间指向不同(或，该五个波束对应不同空间滤波器)。转发器在不同时间单位逐个采用该五个波束可以服务其覆盖范围内不同处于不同地理位置的终端设备。
在图9和图10的示例中，这五个波束所占用的时间是连续的，但本申请不限于此，这五个波束所占用的时间也可以是分散的，或者部分连续部分分散，或者不与第一时间段的起始点和结束点对齐，或者部分与第一时间段的起始点和/或结束点对齐。
在本申请实施例中，如无特别说明，“波束所占时间”是指，网络设备指示转发器使用该波束的时间，和/或，转发器实际使用波束的时间。
在本申请实施例中，第一时间段也可以是周期性的。在不同周期的第一时间段内，波束所占时间在第一时间段中的相对位置相同。但本申请不限于此，在不同周期的第一时间段内，波束所占时间在第一时间段中的相对位置也可以不同。图11和图12示出了在第一时间段是周期性的情况下，网络设备配置转发器在各周期的第一时间段的至少部分时间内，使用上述第一波束至第四波束中的至少一个波束对网络设备和终端设备之间的信号进行转发的情况。
在图11的示例中，在不同周期的第一时间段内，转发器使用波束A将来自网络设备的信号转发给终端设备或者将来自终端设备的信号转发给网络设备，并且，在不 同周期的第一时间段内，波束A所占用的时间长度相同。在图11的示例中，以第一时间段由8个时间单位构成，并且，波束A在每个周期的第一时间段内都占用前四个时间单位为例，本申请不限于此，波束A在每个周期的第一时间段内也可以占用其他时间单位，波束A在每个周期的第一时间段内所占用的时间单位位置可以相同，也可以不同。这里的时间单位可以是符号或者时隙，也可以是其它，本申请不限于此。
在图12的示例中，在不同周期的第一时间段内，转发器使用不同的波束(例如波束A、波束B以及波束C)对网络设备和终端设备之间的信号进行转发。波束A、波束B以及波束C作用相同，即为第一波束至第四波束中的一种。该三个波束空间指向不同(或，该三个波束对应不同空间滤波器)。转发器在不同第一时间段内逐个采用该三个波束可以服务其覆盖范围内不同处于不同地理位置的终端设备。例如，在第一个、第二个、第三个第一时间段内，分别使用波束A、波束B、波束C接收来自所述终端设备的第二信号，此时波束A、波束B、波束C均为前述第二波束，但波束A、波束B、波束C为指向不同的接收波束，或者说，为不同的接收空间滤波器。
并且，在图12的示例中，在每个周期的第一时间段内，波束所占用的时间长度相同，都为前四个时间单位。这里的时间单位可以是符号或者时隙，也可以是其他，本申请不限于此。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
以上仅对与本申请相关的各步骤或过程进行了说明，但本申请不限于此。本申请实施例的方法还可以包括其他步骤或者过程，关于这些步骤或者过程的具体内容，可以参考相关技术。
