Description

波束失败恢复请求的传输资源配置装置、波束失败请求的响应装置、方法及通信系统 技术领域
本发明涉及信息技术领域，尤其涉及一种波束失败恢复请求的传输资源配置装置、波束失败请求的响应装置、方法及通信系统。
背景技术
大规模多入多出(Multiple-Input Multiple-Output，MIMO)技术是新无线(new radio，NR)系统的关键技术，其包括6GHz以下及6GHz以上频段的研究。随着传输频段的增加，传输中产生的衰落和损耗也会相应增大，波束成型(beamforming)技术由于可以有效补偿衰落而成为大规模MIMO中的关键技术。
目前，波束成型技术包括模拟波束成型(analog beamforming，ABF)、数字波束成型(digital beamforming，DBF)以及模拟数字混合波束成型(hybrid beamforming，HBF)。在ABF中，波束成型在模拟域上进行，相比DBF，其实现复杂度低，但是整个时域符号上的波束成型因子均相同。当用户数目较多时，ABF会对调度或用户性能产生一定的限制。在DBF中，波束成型在数字域上进行，每个时频域上的资源粒子都可以根据需要自行调整波束成型因子，但是其复杂度会随着天线数目增多而增大，因而不适用于大规模MIMO系统。HBF是ABF及DBF在性能和处理复杂度上的一种折中方案，既可以在模拟上进行波束成型，也可以在数字域上进行波束成型。但是，HBF仍然要受限于模拟域上的波束成型操作，每个符号上支持的波束个数是有限的。
在NR的研究中，为提高传输的可靠性，允许为物理信道(例如广播信道，数据信道，控制信道等)同时发送多个波束的波束成型技术。然而，在多波束的波束成型技术下，由于高频段的传输特性、移动台的旋转以及障碍物的遮挡等，仍然存在传输失败的情况，称为波束失败。在这种情况下，通过调整服务波束，有可能可以在物理层和介质访问控制(Media Access Control，MAC)层解决传输失败的问题，因而，在NR中引入了波束恢复机制：网络设备(例如传输点(transmission point,TRP))向用 户设备配置监测的物理资源和/或该物理资源监测的波束对，用户设备基于配置的物理资源对控制信道的波束对传输状况进行监测。当用户设备(user equipment，UE)检测到控制信道(例如NR-PDCCH，NR-Physical Downlink Control Channel)传输失败的情况下，可以通过发送上行信号通知网络设备(例如传输点)当前链路传输失败和/或新的服务波束对建议，进而传输点就可以相应地为用户设备选择新的服务波束对以恢复传输。
应该注意，上面对技术背景的介绍只是为了方便对本发明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发明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
当有多个网络设备(如传输点，TRP)为UE服务时，多个网络设备既可以发送相同的数据(如联合传输，joint transmission,JT)，也可以发送不同的数据(如非相干联合传输，non-coherent joint transmission，NC-JT)。在这种场景下，对于某个UE，该UE仅与一个网络设备进行连接，对于该UE，该网络设备被称为服务网络设备，其他网络设备被称为协作网络设备。针对多个网络设备发送不同数据(如NR-PDSCH，NR-Physical Downlink Shared Channel)的情况，NR中引入了多个NR-PDCCH的传输机制，每个NR-PDCCH分别调度不同网络设备发送的NR-PDSCH。
发明人发现，对于某个UE，当多个网络设备发送不同的NR-PDSCH，且多个NR-PDCCH在多个网络设备上发送时，当其中一个网络设备发生波束失败事件时，如果不对其进行波束恢复或其它操作，将会导致该UE无法收到发生波束失败事件的网络设备的数据，进而影响网络设备与UE之间的正常通信。服务网络设备的波束恢复机制可以使用现有的恢复机制，然而，由于协作网络设备不与该UE进行连接，不能发送RRC信令，且所发送的NR-PDCCH类型数量相比服务网络设备也可能会有限制，因此，协作网络设备的波束恢复机制与服务网络设备的波束恢复机制也是不同的。因此，需要设计一种波束恢复机制以应对协作网络设备发生波束失败的情况。

实施例1
本发明实施例提供一种波束失败恢复请求的传输资源配置方法，该方法应用于网络设备侧。图2是本发明实施例1的波束失败恢复请求的传输资源配置方法的示意图。如图2所示，该方法包括：
步骤201：向用户设备发送用于配置关于协作网络设备的波束失败恢复请求的传输资源的配置信息。
在本实施例中，向用户设备发送该配置信息可以在网络设备和用户设备的通信开始时进行发送，即在通信开始时向用户设备配置用于传输波束失败恢复请求的资源。在本实施例中，针对某个用户设备，步骤201可以由协作网络设备执行，也可以由服务网络设备执行。以下分别针对协作网络设备执行步骤201以及服务网络设备执行步骤201来进行说明。
首先针对协作网络设备执行步骤201的情况进行说明。
在步骤201中，对于该用户设备作为协作网络设备时，可以通过协作网络设备的系统信息块(system information block，SIB)或剩余最小系统信息(remaining minimum system information，RMSI)向用户设备发送该配置信息。例如，可以通过发生波束失败的协作网络设备的SIB或RMSI来发送配置信息，且该配置信息可以和与协作网络设备所连接用户的波束失败恢复请求的传输资源的配置信息和/或随机接入前导传输资源的配置信息一起发送。
在步骤201中，协作网络设备可以通过系统信息块或剩余最小系统信息向与该协作网络设备建立通信且与该协作网络设备未连接的用户设备发送该配置信息，或者，通过系统信息块或剩余最小系统信息向与该协作网络设备建立通信且与该协作网络设备未连接和连接的用户设备发送该配置信息。也就是说，该配置信息可以用于对与 该协作网络设备建立通信且未与该协作网络设备进行连接的用户设备的波束失败恢复请求的传输资源资源进行配置，还可以用于和该协作网络所连接用户设备的波束失败恢复请求的传输资源联合进行配置。在本实施例中，在步骤201之前，服务网络设备可以将协作网络设备的小区标识信息(cell ID)、协作网络设备的协作集内部标识信息，协作网络设备的全局标识信息、协作网络设备的波束对链路标识信息以及协作网络设备的其他相关标识信息中的至少一个发送给用户设备。
在本实施例中，该协作网络设备是指发生波束失败的协作网络设备，该小区标识信息例如是该协作网络设备所在小区的小区编号，该协作网络设备的全局标识信息例如是该协作网络设备的全局编号，该协作网络设备的协作集内部标识信息例如是协作网络设备集内的网络设备编号，该其他标识信息例如是可以隐式指示该协作网络设备的标识信息，例如协作网络设备传输时所对应的时域传输资源编号，频域传输资源编号等。
在本实施例中，服务网络设备将协作网络设备的小区标识信息(cell ID)、协作网络设备的协作集内部标识信息，协作网络设备的全局标识信息、协作网络设备的波束对链路标识信息以及协作网络设备的其他相关标识信息中的至少一个发送给用户设备，以使得该用户设备能够译码该协作网络设备的SIB或RMSI，例如，协作网络设备通过广播信令(MIB或SIB)或RRC信令将标识信息发给用户设备，利用该标识信息该用户设备能够译码该协作网络设备所在小区的主系统信息块((master information block，MIB)以获得SIB/RMSI的调度信息，以及解调SIB/RMSI所需的NR-PDCCH。例如，用户设备使用cell ID进行NR-PDCCH和NR-PDSCH的加扰，通过协作网络设备的标识信息来知晓是哪个协作网络设备需要进行波束失败恢复。
在本实施例中，用户设备在译码该协作网络设备的SIB或RMSI后，能够获得该SIB或RMSI中的用于配置波束失败恢复请求信息的传输资源的配置信息，用户设备可以使用随机接入前导序列并在物理随机接入信道(Physical Random Access Channel，PRACH)的非竞争信道上发送波束失败恢复请求信息。接着针对服务网络设备执行步骤201的情况进行说明。
在步骤201中，对于该用户设备作为服务网络设备时，可以通过服务网络设备的无线资源控制(Radio Resource Control，RRC)层的信令向用户设备发送该配置信息。
在步骤201中，可以将该配置信息发送给特定的用户设备，例如，将该配置信息 发送给与服务网络设备连接的用户设备，例如将该配置信息发送给与服务网络设备连接的且具有相同协作网络设备集合的用户设备。
在本实施例中，该配置信息可以包含特定用户设备的相关服务网络设备和协作网络设备分别发生波束失败时传输波束失败恢复请求信息的传输资源配置，例如，该配置信息包括与服务网络设备连接的用户设备的服务网络设备和协作网络设备分别发生波束失败时波束失败恢复请求的传输资源配置。每个用户设备采用的传输方案可以不同，例如，单个网络设备服务方案，多个网络设备服务方案，另外，协作网络设备集合也可能会不同。
在本实施例中，该配置信息不仅可以包括对应于发生波束失败的协作网络设备的波束恢复请求信息的传输资源的配置，还可以包括服务网络设备本身发生波束失败时的波束恢复请求信息的传输资源的配置。也就是说，该配置信息可以包括对应于与该用户设备通信的所有网络设备的波束恢复请求信息的传输资源的配置。
在本实施例中，该配置信息中用于传输波束恢复请求的资源可能有多个，该用户设备收到该配置信息之后，在发生波束失败的情况下，可以在配置的传输资源中任意选择一个或多个传输资源来发送波束恢复请求信息。
在本实施例中，服务网络设备在向用户设备配置用于传输波束恢复请求的资源时，还可以进行一些其他的配置。例如，还可以发送服务网络设备及协作网络设备的NR-PDCCH相关的准共址(Quasi-co-location)假设配置信息和/或NR-PDCCH的控制资源集合(control resource set，CORESET)的物理资源配置信息等。这些信息例如可以用于检测波束失败事件。例如，为了对服务网络设备及协作网络设备的NR-PDCCH配置信息进行区分，该准共址假设配置信息和/或NR-PDCCH的控制资源集合的物理资源配置信息等可以以分组的形式进行配置，仅组编号对用户设备可知；也可以在配置以上信息时，将服务网络设备及协作网络设备的标识信息加入用于用户设备对多个NR-PDCCH的配置进行区分。
由上述实施例可知，通过本发明实施例，能够有效的应对协作网络设备发生波束失败的情况，保证网络设备与用户设备之间的正常通信。

步骤403：当发生波束失败时，用户设备根据该配置信息配置的传输资源任意选择一个或多个向发生波束失败的协作网络设备发送波束恢复请求信息。
由上述实施例可知，通过本发明实施例，能够有效的应对协作网络设备发生波束失败的情况，保证网络设备与用户设备之间的正常通信。
实施例4
本发明实施例还提供一种波束失败的处理方法，该方法应用于协作网络设备侧。 图5是本发明实施例4的波束失败的处理方法的示意图。如图5所示，该方法包括：
步骤501：放弃波束失败恢复，并将波束失败事件和/或缓存剩余数据发送给服务网络设备。
在本实施例中，发生波束失败的协作网络设备放弃波束失败恢复，并将波束失败事件和/或缓存剩余数据发送给服务网络设备。这样，服务网络设备在接收到该缓存剩余数据的情况下，将该缓存剩余数据发送给用户设备，从而完成发生波束失败的协作网络设备的剩余数据的传输。
在本实施例中，协作网络设备是否执行步骤501，即，是否放弃波束恢复，可以根据通信系统的实际情况而设置。例如，可以根据用户设备的能力、协作网络设备的能力以及服务网络设备的负载来确定，并通过RRC信令对用户设备进行配置。
由上述实施例可知，通过本发明实施例，能够有效的应对协作网络设备发生波束失败的情况，保证网络设备与用户设备之间的正常通信。
实施例5
本发明实施例还提供一种波束失败的处理方法，该方法应用于服务网络设备侧。
图6是本发明实施例5的波束失败的处理方法的示意图。如图6所示，该方法包括：
步骤601：从协作网络设备接收波束失败事件和/或缓存剩余数据，并在接收到该缓存剩余数据的情况下，将该缓存剩余数据发送给用户设备。
在步骤601中，服务网络设备可以从协作网络设备接收波束失败事件和/或缓存剩余数据，并在接收到该缓存剩余数据的情况下，将该缓存剩余数据发送给用户设备。该步骤例如对应于实施例4的步骤501的情况。也就是说，发生波束失败的协作网络设备放弃波束失败恢复，并将波束失败事件和/或缓存剩余数据发送给服务网络设备，服务网络设备从协作网络设备接收波束失败事件和/或缓存剩余数据，并在接收到该缓存剩余数据的情况下，将该缓存剩余数据发送给用户设备。
由上述实施例可知，通过本发明实施例，能够有效的应对协作网络设备发生波束失败的情况，保证网络设备与用户设备之间的正常通信。
实施例6
本发明实施例还提供一种波束失败的处理方法，该方法应用于网络设备侧和用户设备侧，其对应于实施例4和5，其中与实施例4和5相同的内容不再重复说明。
图7是本发明实施例6的波束失败的处理方法的示意图。如图7所示，该方法包括：
步骤701：协作网络设备放弃波束失败恢复；
步骤702：将波束失败事件和缓存剩余数据发送给服务网络设备；
步骤703：服务网络设备将该缓存剩余数据发送给用户设备。
由上述实施例可知，通过本发明实施例，能够有效的应对协作网络设备发生波束失败的情况，保证网络设备与用户设备之间的正常通信。
实施例7
本发明实施例还提供一种波束失败恢复请求的响应方法，该方法应用于网络设备侧。图8是本发明实施例7的波束失败恢复请求的响应方法的示意图。如图8所示，该方法包括：
步骤801：向用户设备发送关于协作网络设备的波束失败恢复请求的响应信息。
在本实施例中，针对某个用户设备，步骤801可以由协作网络设备执行，也可以由服务网络设备执行。以下分别针对协作网络设备执行步骤801以及服务网络设备执行步骤801来进行说明。
首先针对协作网络设备执行步骤801的情况进行说明。
在本实施例中，对于协作网络设备，在步骤801之前，该方法还可以包括：
步骤802：从用户设备或服务网络设备接收关于协作网络设备的波束失败请求；
在本实施例中，该波束失败恢复请求可以是该协作网络设备收到的，也可以是服务网络设备收到后转发给该协作网络设备的，本发明实施例不对该波束失败恢复请求收到的方式进行限制。
在步骤801中，协作网络设备发送该响应信息的方式可以和服务网络设备对于波束失败请求的响应方式相同，也可以不同。
例如，服务网络设备发送波束失败请求的响应信息时可能会包含接入相关的信息，例如，基于竞争的随机接入过程的随机接入响应或竞争解决等信息。因此，步骤701中的响应信息可以包括接入相关信息，也可以不包括接入相关信息。
在步骤801中，协作网络设备可以通过向该用户设备发送数据信道来发送该响应信息。
例如，该方法还可以包括：向该用户设备发送用于调度该数据信道的控制信道。
例如，协作网络设备可以通过向该用户设备发送NR-PDSCH来发送该响应信息，该NR-PDSCH需要由协作网络设备发送额外的NR-PDCCH对该NR-PDSCH进行调度，且该NR-PDCCH的CRC的加扰信息由用户设备所选择的波束失败恢复请求信息的传输资源决定，例如，其计算方法类似于LTE或系统中的RA-RNTI计算。
接着针对服务网络设备执行步骤801的情况进行说明。
在本实施例中，对于服务网络设备，在步骤801之前，该方法还可以包括：
步骤803：从用户设备或协作网络设备接收关于协作网络设备的波束失败请求。
在本实施例中，该波束失败恢复请求可以是该协作网络设备收到后转发给服务网络设备的，也可以是直接从用户设备获取的，本发明实施例不对该波束失败恢复请求收到的方式进行限制。
在步骤801之前，该方法还可以包括：
步骤804：从协作网络设备接收响应信息包含的部分信息或全部信息。
例如，该响应信息可以包括发生波束失败事件的协作网络设备的小区标识信息、协作网络设备的协作集内部标识信息，协作网络设备的全局标识信息、协作网络设备的波束对链路标识信息以及协作网络设备的其他相关标识信息中的至少一个。
例如，该响应信息还可以包括发送该波束失败请求的用户设备标识(UE ID)，例如UE编号，还可以包括新的候选波束相关信息，例如，准共址(Quasi-co-location)假设，新的候选波束的波束或时频资源编号等。
在本实施例中，例如，协作网络设备通过Xn接口将响应信息包含的部分信息或全部信息发送给服务网络设备。
在步骤802中，可以通过服务网络设备的数据信道向该用户设备发送该响应信息。
例如，服务网络设备可以通过NR-PDSCH向该用户设备发送该关于协作网络设备的波束失败请求的响应信息。调度该NR-PDSCH的NR-PDCCH的CRC加扰信息由用户设备所选择的波束失败恢复请求信息的传输资源决定，例如，其计算方法类似于LTE或系统中的RA-RNTI计算。在本实施例中，服务网络设备向用户设备发送关于协作网络设备的波束失败请求的响应信息，另外，当该服务网络设备也发生波束失败而收到来自用户设备的波束恢复请求时，其也需要向用户设备发送关于服务网络设备自身的波束失败请求的响应信息。在这种情况下，为了区分这两种响应信息，可以 将这两种信息划分为两种类型。例如，类型1表示关于服务网络设备自身的波束失败请求的响应信息，类型2表示关于协作网络设备的波束失败请求的响应信息。
在本实施例中，类型1和类型2的响应信息可以定义为具有不同的格式，也可以定义为具有相同的格式。另外，可以将类型1和类型2的响应信息定义为具有相同的尺寸，以相互兼容。也可以不对响应类型进行区分，而是在响应信息中包含发生波束失败事件的网络设备相关标识，例如，将服务网络设备或发生波束失败事件的协作网络设备的小区标识信息、协作网络设备的协作集内部标识信息，协作网络设备的全局标识信息、协作网络设备的波束对链路标识信息以及协作网络设备的其他相关标识信息中的至少一个发给用户设备。例如，该协作网络设备是指发生波束失败的协作网络设备，该小区标识信息例如是该协作网络设备所在小区的小区编号，该协作网络设备的全局标识信息例如是该协作网络设备的全局编号，该协作网络设备的协作集内部标识信息例如是协作网络设备集内的网络设备编号，该其他标识信息例如是可以隐式指示该协作网络设备的标识信息，例如协作网络设备传输时所对应的时域传输资源编号，频域传输资源编号等。
在本实施例中，该方法可以对应于实施例1的处理，也可以不对应于实施例1。本发明实施例不对其是否具有对应关系进行限定。
由上述实施例可知，通过本发明实施例，能够有效的应对协作网络设备发生波束失败的情况，保证网络设备与用户设备之间的正常通信。
实施例8
本发明实施例还提供一种波束失败恢复请求的响应方法，该方法应用于网络设备侧和用户设备侧，其对应实施例7，其中与实施例7相同的内容不再重复说明。
图9是本发明实施例8的波束失败恢复请求的响应方法的示意图。如图9所示，该方法包括：
步骤901：用户设备向协作网络设备发送关于该协作网络设备的波束失败恢复请求；或者
步骤902：用户设备向服务网络设备发送该关于协作网络设备的波束失败恢复请求；
