Description

基于波束的多连接通信方法、终端设备及网络设备 技术领域
本发明涉及高频无线通信领域，尤其涉及一种基于波束的多连接通信方法、终端设备及网络设备。
背景技术
在高频无线通信领域中，随着频率的增大会使无线信号路径损耗增大，小区覆盖范围减小，导致在相同的面积内需要部署更多接入网设备(接入网设备可以是基站或发射接收端点(英文：transmission reception point，TRP))，才能够保证覆盖，极大地增加网络部署成本，这就需要提供一种覆盖增强通信方法。
现有技术通过波束成形技术(即一种多天线处理技术)，使用多个天线形成窄波束，获得波束增益，在一定程度上补偿路径的损耗。如图1所示，A区域为低频覆盖范围，B区域为高频覆盖范围，C区域为窄波束覆盖范围，L为基站覆盖的小区边界；由于窄波束的波束增益较高，从而补偿了高频的路径损耗。为了保证小区内的连续覆盖，需要使用多个窄波束，如若每个窄波束的宽度为10°，则36个相同的窄波束将覆盖整个小区。对于终端来说，首先通过随机接入过程完成终端和基站间的初始波束对齐(即终端和基站的初始波束连接)，即终端搜索其与基站间的一个服务波束，服务波束是终端能接收到的所有波束中信号质量最好的波束。然后随着终端的移动、旋转和信道变化，终端还需要进行波束跟踪，即终端实时测量所有波束的信号质量，并将测量结果上报给基站，基站决定是否进行服务波束的切换，如果需要切换，就通过指示消息通知终端。
然而，高频通信信道变化剧烈，经常有信道质量大幅下降的情况发生，信号传播路径一般为直射和反射路径，容易受到障碍物影响。当服务波束发生阻塞时，导致终端和基站间的数据中断，终端的波束跟踪机制不能继续运行，只能再次通过随机接入过程重新进行波束对齐，从而增加系统的信令开销。

具体实施方式
下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。
本发明提供的波束通信方法应用于高频无线通信场景的蜂窝通信网络中。本发明描述的技术可以适用于长期演进(英文：Long Term Evolution,LTE)系统，或其他采用各种无线接入技术的无线通信系统，例如采用码分多址，频分多址，时分多址，正交频分多址，单载波频分多址等接入技术的系统。此外，还可以适用于使用LTE系统后续的演进系统，如第五代5G系统或新空口(英文：new radio，NR)系统等。
本发明中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。本发明所涉及到的终端设备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(英文：wearable device，WD)、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(英文：user equipment,UE),移动台(英文：mobile station,MS)，终端(terminal)，终端设备(英文：terminal equipment)等等。本发明所涉及到的基站(英文：base station,BS)是一种部署在无线接入网中用以为终端提供无线通信功能的网络设备。所述基站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，具备基站功能的设备的名称可能会有所不同，例如在LTE网络中，称为演进的节点B(英文：evolved NodeB,eNB或者eNodeB),在第五代5G或NR网络中，称为新空口基站(英文：new radio NodeB，NR-NB)等等。为方便描述，本发明中上述的终端设备可以统称为UE，上述为UE提供无线通信功能的网络设备可以统称为基站。
下面针对本发明实施例中用到的主要网元进行详细介绍：
eNB用于在下行方向上通过形成窄波束扩大覆盖范围，在上行方向上也可以通过不同波束接收不同方向的信号。该eNB可以支持在任一时刻使用两个或两个以上波束进行数据的发送和接收。
TRP用于在下行方向上通过形成窄波束扩大覆盖范围，在上行方向上也可以通过不同波束接收不同方向的信号。
UE用于通过搜索eNB/TRP发出的参考信息(如同步信号，或导频信号)，确定可用波束，并将选择结果反馈给eNB/TRP。同时，如果在UE侧部署了多个天线，则在UE侧也可以使用波束形成的收发技术形成多个发送接收波束。如图2所示，UE可以通过多个波束与多个TRP(如TRP1与TRP2)通信，也可以通过多个波束与一个TRP(如TRP1或TRP2)通信。该UE可以支持在任一时刻使用两个或两个以上波束进行数据的发送和接收。
如图3A所示的LTE通信系统中，在一个移动管理实体(英文：mobile managenment entity，MME)的控制下有至少一个eNB，每个eNB下存在多个小区，在每个小区中eNB可以使用多个发送波束完成小区覆盖，从而达到与UE通信。
如图3B所示的5G或NR系统中，在一个NR-NB的控制下，可能存在一个或多个TRP，每个TRP都能形成多个波束，在每个小区中TRP可以使用多个发送波束完成小区覆盖，从而达到与UE通信。
进一步的，由于每个波束覆盖的面积有限，要完成一个小区的覆盖都要经过波束的扫描过程。当基站通过多个窄波束完成小区覆盖时，基站可以按照时分/频分/波分的方式或 其组合方式进行数据的发送或接收。对于时分方式，每个波束使用的时间长度可以单独设置，可以是一个或多个子帧，也可以是一个或多个符号。如图4所示，基站可以通过时分复用的方式完成整个小区的覆盖，该基站有8个波束，且该8个波束分别用数字符号0-7进行标识；横轴为时间轴,在时间轴上存在至少一个上行接收子帧(英文：uplink，UL)和至少一个下行接收子帧(英文：downlink，DL)；每个数字符号代表的波束按时间的先后发给UE，并且每个数字符号代表的波束占用的时间段A至时间段G相同。当基站接收上行数据时，在一个单独的上行接收子帧上，每个符号只接收相应波束方向上的数据。当基站发送下行数据时，在一个单独的下行发送子帧上，每个符号只发送相应波束方向上的数据。
本发明实施例中终端UE使用第一波束与基站的通信连接后，再次使用第二波束建立与基站的波束通信连接，从而建立UE与基站间的多波束连接。
可选地，终端UE使用第一波束对中的第一波束与基站通信连接后，终端UE使用第二波束对中的第二波束与基站通信连接，其中，第一波束对包括终端UE的第一波束和基站的第一波束。第二波束对包括终端UE的第二波束和基站的第二波束。
该通信连接可以是UE与基站间建立的无线资源控制(英文：Radio Resource Control，RRC)连接。
可选地，终端UE使用第一波束与基站建立通信连接的过程可以是随机接入过程。
图5为本发明实施例提供的一种基于波束的多连接通信方法的信令交互图，如图5所示，该方法可以包括：
步骤510、基站通过多个波束向UE发送参考信号。
参考信号可以是同步信号，同步信号用于UE获取下行同步，在获得下行同步后，才能正确获得基站的指示消息，例如，分配给UE的传送数据或控制信令的上行链路资源。
基站通过多个发送波束向UE发送同步信号，即一个发送波束传输一个同步信号，且每个发送波束传输的同步信号可以相同或不同。除同步信号，各个波束也可以有单独的专用于信道估计的参考信号。
步骤520、UE对基站的多个波束传输的参考信号进行测量，确定第一波束对，第一波束对包括UE的第一发送波束和基站的第一接收波束。
UE使用本地多个接收波束对基站下发的多个发送波束中传输的参考信号进行信号质量测量，选择信号质量最好的一个第一发送波束作为发送波束，以及在UE的多个接收波束中选择信号质量最好的一个第一接收波束作为接收波束。由此UE确定第一波束对，该第一波束对包括UE的第一发送波束与基站的第一接收波束，采用这一波束对获得的参考信号质量最好，即最优波束对。其中，信号质量可以用每个波束的参考信号接收功率(英文：reference signal receiving power，RSRP)或参考信号接收质量(英文：reference signal receiving quality，RSRQ)的值来衡量。
可选地，UE的最优发送波束与基站的最优接收波束形成最优上行波束对；UE的最优接收波束与基站的最优发送波束形成最优下行波束对。其中，最优上行波束对和最优下行波束对可以是同一个波束对，也可以是不同波束对。
当满足信道互易性时，最优上行波束对和最优下行波束对是同一个波束对。当不满足 信道互易性时，最优上行波束对和最优下行波束对是不同的波束对，即属于一个波束连接中的下行最优波束对和上行最优波束对不是同一对波束，上行最优波束对的确定过程也可以在随机接入过程中实现，本发明不再详细描述。本发明后续描述中默认可以应用信道互易性，不能应用信道互易性的场景对于本发明没有实质影响，不再赘述。
步骤530、在基站的第一波束的接收时刻，UE通过的第一上行波束向基站发送随机接入前导码消息。
在执行步骤530之前，在UE完成下行同步，并接收基站发送的系统消息获得小区随机接入资源配置后，UE在任意的随机接入时频资源上随机选择一个前导码。
随后，UE在基站的第一波束的接收时刻，通过UE第一波束向基站发送随机接入前导码消息。
步骤540、在基站的第一波束的发送时刻，基站通过第一波束向UE发送随机接入响应消息。
在执行步骤540之前，基站根据收到的随机接入前导码，计算相应的定时提前(英文：timing advance,TA)值。
在基站的第一波束的发送时刻，基站通过第一波束向基站发送随机接入响应消息，随机接入响应消息可以包括TA值和上行调度许可(英文：uplink grant，UL-Grant)。其中，TA值用于实现UL同步，UL-Grant用于指示UE的UL发送数据。
步骤550、在基站的第一波束的接收时刻，UE通过的第一波束向基站发送第一消息，该第一消息中可以包括UE的标识信息。
第一消息可以是RRC连接建立请求消息；UE的标识信息可以是小区无线网络临时标识(英文：Cell-RadioNetworkTemporaryIdentifier，C-RNTI)。
UE根据接收到的UL-Grant的资源指示和TA值，在基站的第一波束的接收时刻，向基站发送RRC连接建立请求消息，该消息中可以包括UE的标识信息，以使基站识别出该UE。
需要说明的是，第一消息可以根据不同的下行信道场景包含不同的内容。比如波束连接建立请求、RRC连接建立请求，或重建请求等信息。
步骤560、在基站的第一波束的发送时刻，基站通过第一波束向基站发送第一消息的响应消息，以建立通信连接。
第一消息的响应消息可以是RRC连接建立确认消息，UE接收到RRC连接建立确认消息后，UE与基站完成RRC连接的建立。
需要说明的是，第一消息的响应消息可以根据不同的上行信道场景包含不同的内容，或根据第一消息的不同内容而包含不同的信息。
可选地，在终端UE使用第一波束与基站建立通信连接(RRC连接)之后，UE可以向基站发送该UE的最大连接阈值，即该UE能够支持的最大波束连接的个数。UE的最大连接阈值可以作为基站判断UE是否还可以进行波束连接的参考值，也可以作为基站判断UE是否可以进行波束连接替换的参考值。
需要说明的是，在本发明实施例UE确定波束对之后的信息交互过程中，UE与基站都会选择在对方波束的接收时刻发送指令信息。
图6为本发明实施例提供的一种基于波束的多连接通信方法的信令交互图，如图6所 示，该方法可以包括：
步骤610，基站使用多个第二波束中每个波束向终端UE发送参考信号。此处基站的第二波束是指除第一波束对中基站的第一波束之外的其他波束。
该参考信号用于终端UE进行信道估计。
步骤620，终端UE根据参考信号，对基站的多个第二波束的信号质量进行测量，确定第二波束对。
终端UE使用多个第二波束接收参考信号。UE通过接收基站的多个第二波束中每个波束发送的参考信号，对多个第二波束进行信道估计，获取多个第二波束的属性信息，如信号质量信息等。
终端UE根据属性信息，对基站的多个第二波束的信号质量进行测量，获取测量结果。
UE根据测量结果，从UE的多个第二波束中，确定出与基站的每个第二波束匹配的每个第二波束。
需要说明的是，UE对基站的多个波束进行测量的过程可以是周期性的，也可以是由基站触发的。优选的，考虑到测量的准确性与实时性，本发明实施例中UE对基站的多个波束进行周期性测量。
可以理解的是，终端UE还可以通过其他方式确定第一波束对，本发明实施例在此不做限定。
步骤630，终端UE使用第二波束，向基站发送随机接入前导码消息。
步骤640、基站根据随机接入前导码消息并使用第二波束，向终端UE发送随机接入响应消息。
步骤650、终端UE根据随机接入响应消息并使用第二波束，向基站发送第一消息，第一消息可以包括终端UE的标识信息和波束建立请求信息。
第一消息是可以是MAC CE消息，也可以是RRC消息，UE的标识信息可以是C-RNTI。
可选地，当第一消息是MAC CE消息时，该MAC CE消息包括消息子头和载荷部分，UE可以通过重新配置MAC CE子头结构中的逻辑信道标识(LCID)的值，来指示波束建立请求、波束建立确认或波束建立拒绝等信息；UE还可以通过重新配置MAC CE消息的载荷结构，来指示波束建立请求、波束建立确认或波束建立拒绝等信息
如图7所示，MAC CE子头部分的结构中可以包括一个比特的预留位R域、一个比特的F2域、一个比特的E域，和5个比特的LCID字段。其中，F2是格式域，用于指示长度域的长度，E是扩展域，扩展域是一个标志位，指示MAC头部中是否还有其他的域。UE可以通过选择索引值为01011-11000中的每个索引对应的LCID的值为来指示波束建立请求、波束建立确认或波束建立拒绝等信息，具体对应关系由协议规定。
如图8所示，MAC CE载荷部分的结构可以包括两个比特的预留R位和新增加的六个比特的波束索引位。UE可以通过配置增加或减少R位的个数来指示波束建立请求、波束建立确认或波束建立拒绝等信息；波束索引位指示待连接的波束索引。需要说明的是，根据通信需要，MAC CE载荷部分的R位的个数可以为0到7的任意数，例如若R位为2比特(即2位)，则波束索引位为6比特。
需要说明的是，该指示信息的配置过程可以上述图7与图8所示的过程，也可以根据 设计需要采用其他的配置过程，本发明在此不做限定。
可选地，当第一消息是RRC消息时，UE可以通过在RRC消息中携带指示信息，该指示信息用于指示波束连接建立请求、波束连接建立确认或波束连接建立拒绝等信息。
步骤660、基站根据UE的标识信息和波束连接建立请求信息并使用第二波束，向UE发送的第一响应消息，以使UE与基站建立第二波束连接。
可选地，第一响应消息可以包括波束连接建立确认信息、波束连接建立拒绝信息或RRC建立确认信息。
基站根据UE的标识信息，判断UE与该基站是否已建立RRC连接。
若UE与该基站未建立RRC连接，则基站向UE发送的第一响应消息，第一响应消息包括波束建立请求信息，以指示使UE与基站建立RRC连接。
进一步的，若UE与该基站已建立RRC连接，则基站将进一步对基站的第二波束进行识别。基站可以根据基站的连接准则，对基站的第二波束进行识别，该准则可以包括保证信号质量高于预置门限，和/或确定的第二波束与第一通信连接(RRC连接)中基站的第一波束不属于同一个TRP，从而保证了波束连接后良好的信号质量，还可以避免同一个TRP引起的信号同步变化现象，如同步衰减。
可选地，当该第二波束与第一波束连接中的第一波束不是同一TRP时，基站向UE发送的第一响应消息，以指示使UE与基站建立第二波束连接；
当该第二波束与第一波束连接(RRC连接)中的第一波束是同一TRP时，基站向UE发送的第一响应消息，以指示波束连建立拒绝。
需要说明的是，基站的连接准则还可以包括其他类型信息，如UE的属性信息，如UE的最大连接阈值等。若UE的波束连接达到最大连接阈值，则基站可以选择拒绝建立新的波束连接；也可以选择通过删除已有的波束连接，添加新的波束连接。若UE的波束连接未达到最大连接阈值，则基站可以选择确认建立新的波束连接。
本发明实施例的上述方法是基于终端与基站已建立通信连接(RRC连接)的基础上，随后终端UE触发并通过随机接入过程建立其他多波束的通信连接。

步骤930、终端UE使用第一波束，向基站发送测量报告，测量报告包括基站的多个波束的信号质量的测量结果。
步骤940、基站根据测量结果，确定第二波束。
基站根据终端UE测量出的测量结果，并依据一定的连接准则，从除第一波束对外的其他波束中选择一个波束，作为第二波束。
该准则可以包括保证波束的信号质量高于预置门限，和/或确定的第二波束与第一通信连接(RRC连接)中基站的第一波束不属于同一个TRP，从而保证了波束连接后良好的信号质量，还可以避免同一个TRP引起的信号同步变化现象，如同步衰减。
可以理解的是，终端UE还可以通过其他方式确定第一波束对，不限于上述步骤910-步骤940的方式，本发明实施例在此不做限定。
步骤950、基站使用第一波束向终端UE发送第一消息，第一消息包括第一指示信息。

可选地，当第一消息是MAC CE消息时，该MAC CE消息包括消息子头和载荷部分，基站可以通过配置逻辑信道标识(LCID)的值，来指示专用随机接入前导码资源和波束建立请求等信息，基站还可以通过改变MAC CE载荷部分的字段结构来指示基站的第二波束的索引信息。
需要说明的是，该第一指示信息的配置过程可以参考图7与图8所示的过程，也可以根据设计需要采用其他的配置过程，本发明在此不做限定。
可选地，当第一消息是PDCCH order消息时，基站可以通过增加PDCCH order消息中的数字版权唯一标识符(英文：downlink control information，DCI)的比特位的数量，指示基站的第二波束索引信息和波束建立请求等信息。
需要说明的是，若上述各消息包括的波束索引可以是完整的波束索引，也可以是基站为了节省系统开销，采用最近一次UE波束测量结果中的顺序索引。表1为本发明实施例提供的一种波束索引与波束测量顺序索引的对照表。
表1

当基站使用第二波束向终端发送第一消息时，终端UE识别基站的第二波束，并从除第一波束外的其他波束中选择与基站的第二波束匹配的第二波束，从而确定第二波束对。
当基站通过除第一波束和确定的第二波束以外的发送波束向UE发送第一消息时，终端UE根据第一消息中的第一指示信息(如第二波束的索引信息)，确定与基站的第二波束匹配的第二波束，从而确定第二波束对。
