Description

信息上报的触发方法和装置、信号的选择方法和装置
本申请要求在2017年08月11日提交中国专利局、申请号为201710687049.2的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如涉及一种信息上报的触发方法和装置、信号的选择方法和装置。
背景技术
在无线通信系统中，基站利用多根天线的波束成型能力，采用更窄波束传输能够有效提升传输效率，因此未来的无限通信发展趋势将是采用多个窄波束将小区分为多个更加动态的虚拟扇区(virtual vectors)来对用户提供各种服务。每个波束的服务范围可以利用波束权值进行灵活的调整。
但是利用窄波束传输会对用户(User Equipment，UE)移动和波束链路的阻塞会比较敏感，例如在高频中，阻塞现象比较严重，经常引起链路失效。因此当无线信道因为上述原因产生信道变化时，通信系统需要快速的进行波束链路切换和恢复，才能提供好的用户体验。
由于在多波束通信系统中，控制信道的传输也需要使用SS波束或CSI-RS波束进行传输，一旦出现波束失效时，如果基站侧无法快速的获知这一情况，就无法发送下行控制信令，上下行传输都无法发起，造成整个通信链路的瘫痪，目前还没有能够触发协议高层的链路失效相关流程、并发起重新接入的技术方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
下面对本申请提及的专业术语进行简单解释：
QCL，Quasi-co-location，参考信号。
PDCCH，Physical downlink control channel，物理下行控制信道。
DCI，英文全称为Downlink control signaling，由下行物理控制信道PDCCH承载，eNB发送给UE的下行控制信息，包括上下行资源分配、HARQ信息、功率控制灯。
CSI-RS，英文全称为Channel state information reference signal，信道状态信息参考符号。
PUCCH，英文全称为Physical uplink control channel，物理上行控制信道。
PRACH，英文全称为Physical random access channel，物理随机接入信道。
SS，英文全称为Synchronization signal，同步信号。
SINR，英文全称为signal to interference plus noise ratio，信号与干扰加噪声 比。
RSRP，英文全称为Reference signal receiving power，参考信号接收功率。
采用多波束的通信系统如图1所示，基站会利用射频或基带预编码技术，在信道特征空间或实际的3D空间中形成多个有着方向性的波束(对应于多个虚拟扇区)，从同步信号开始，基站就采用波束方式进行发送，如图2所示。一个小区中可以存在多个SS波束，每个SS波束可以用准共位置(QCL)关系关联多个CSI-RS(估计信道状态的导频)波束，表征其有着近似的波束指向。
CSI-RS一般采用窄波束，SS也是采用窄波束发送，但SS的波束宽度一般情况相对于CSI-RS来说还是会略宽一些。基站可以采用最佳的CSI-RS波束对应的预编码权值或SS波束对应的预编码权值作为控制或数据传输的参考权值。但前提是要能够获取最佳波束信息。最基本流程的步骤包括：步骤S11、步骤S12和步骤S13。
在步骤S11中，基站发送不同方向的波束参考信号(SS或CSI-RS)，并将参考信号的配置信息通知接收端。
在步骤S12中，终端测量这些波束参考信号的接收质量，并从中选择质量较好的参考信号，反馈其对应的指示信息给基站。
在步骤S13中，基站使用终端上报的这些参考信号对应的预编码对数据进行传输。
在上述技术方案中，波束存在如下的质量问题：
基站获取了波束信息和CSI信息后，可以将其用于下行传输。但随着工作频率越来越高，可部署的天线数目越来越多，为了应对高频路径损耗的增大，使用的波束会越来越窄。控制信道和数据信道等都会使用波束进行传输。虽然采用波束传输有着很高的传输效率，但是传输鲁棒性(robustness)并不是很好。主要的原因是由于波束较窄，经常会因为出现终端移动、手持终端旋转、传播路径被遮挡造成服务波束的质量明显下降，导致不能正常通信。
实施例1
本申请实施例一所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置(如用户设备和基站)中执行。以运行在移动终端上为例，图3是本申请实施例的一种信息上报的触发方法的移动终端的硬件结构框图。如图3所示，移动终端30可以包括一个或多个(图3中仅示出一个)处理器302(处理器302可以包括但不限于微处理器(Microcontroller Unit，MCU)或可编程逻 辑器件(Field-Programmable Gate Array，FPGA)等的处理装置)、设置为存储数据的存储器304、以及设置为通信功能的传输装置306。本领域普通技术人员可以理解，图3所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，移动终端30还可包括比图3中所示更多或者更少的组件，或者具有与图3所示不同的配置。
存储器304可设置为存储应用软件的软件程序以及模块，如本申请实施例中的信息上报的触发方法对应的程序指令/模块，处理器302通过运行存储在存储器304内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器304可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器304可进一步包括相对于处理器302远程设置的存储器，这些远程存储器可以通过网络连接至移动终端30。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置306设置为经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端30的通信供应商提供的无线网络。在一个实例中，传输装置306包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置306可以为射频(Radio Frequency，RF)模块，其设置为通过无线方式与互联网进行通讯。
申请人认识到，当无线信道因为前述原因产生信道变化时，通信系统需要快速的进行波束链路切换和恢复，才能提供好的用户体验。因此可引入本申请的波束恢复技术。波束恢复技术的主要包括以下步骤S21-步骤S24。
在步骤S21中，波束监测，主要是进行波束失效(beam failure)判断。
在步骤S22中，波束选择，选择新的波束用于重建传输链路。
在步骤S23中，信息上报，上报波束恢复相关信息，如终端指示信息以及波束指示信息等。
在步骤S24中，DCI检测，在新建立的链路的控制信道上检测DCI。
在本申请的波束恢复技术中，所提供的技术方案主要解决以下的四个方面的问题。
(1)技术问题1：波束监测中如何进行波束失效判断来避免误判。
(2)技术问题2：波束选择中如何确定候选参考信号资源(也即导频资源) 以提高资源利用率。
(3)技术问题3：终端如何上报波束恢复相关的信息才能更好的适应各种的波束问题。
(4)技术问题4，终端如何检测控制信道才能更准确的进行波束恢复。
下面逐一介绍本申请如何解决上述的问题。
(一)对于上述技术问题1
波束失效的判断会明显地影响波束恢复发起的概率，过小的触发概率容易影响波束恢复性能，而过大的触发概率则会引起不必要的波束恢复，造成一些资源浪费和传输效率的降低。相关技术并没有具体的优化方案。本申请可通过一个简单的门限来判断波束是否失效。
终端测量波束质量信息，如果波束质量高于该门限，则判断为波束未失效，无需上报信息给基站，如果波束质量低于该门限，则判断为波束失效，需要进行波束恢复。这种方式面临准确性的问题，因为测量结果往往会受到干扰的影响，还会面临参考信号的统计不充分影响。而且波束参考信号的质量也不能完全的反映控制或数据信道传输的质量。基于此，本申请还提出了以下一些方案来提高波束失效判断的准确性。
后续以第一通信节点为终端(第一通信节点还可以为其余用户终端、移动终端)，第二通信节点为基站(第二通信节点还可以为能够提供用户服务的设备)为例详述本申请的实施例。
(1)方案一
本申请实施例提供了一种运行于上述移动终端的信息上报的触发方法，图4是根据本申请实施例的信息上报的触发方法的流程图，如图4所示，该流程包括如下步骤S402和步骤S404。
在步骤S402中，终端获取第一信息。
其中，第一信息用于推荐质量门限的配置(此处的推荐是指：第一信息向基站指示质量门限的配置，由基站自主确认是否采用)，质量门限用于终端判断是否需要触发第二信息的上报，第二信息用于指示下行传输信息。
在步骤S404中，终端向基站上报第一信息。
通过上述步骤，终端向基站发送第一信息，第一信息用于推荐质量门限的配置，质量门限用于终端判断是否需要触发第二信息的上报，第二信息用于指示下行传输信息，解决了相关技术中不能触发协议高层的链路失效相关流程的 技术问题，实现了触发协议高层的链路失效相关流程的功能。
在一实施例中，上述步骤的执行主体可以为终端，但不限于此。
在一实施例中，第二信息指示的下行传输信息包括以下至少之一：终端的终端标识(也即节点标识)的指示信息、参考信号的指示信息、波束的指示信息、波束恢复的请求信息、参考信号发送的请求信息、以及波束质量的指示信息。
在一实施例中，可由基站直接配置门限值，但由于考虑到每个UE的接收机能力不同，对于相同的RSRP或SINR及码率参数，可能会有不同的接收性能。有的终端通过接收端干扰处理的算法可以非常好的利用接收端多天线处理掉干扰，明显提升SINR。因此用户终端UE根据接收机来推荐门限参数可以设置为基站更准确配置波束恢复质量门限，在波束恢复的性能和资源效率之间获得比较好平衡。
若采用单门限的配置方法，如图5所示。这种方式对门限的设置有非常高的要求。实际上仅仅通过一种质量门限就判断是否发生波束失效并不是一种非常准确的方式，因为参考信号的质量和控制信道的实际传输质量虽然有相关性，但并不是完全等价的。
在这里，为了更好的利用测量信息反映实际的传输质量，本申请还提出一种新的方法如图6所示。主要思想是采用多个门限的波束失效判断方式，这样可以使得波束失效的判断更准确。
(2)方案二
本申请实施例提供了一种运行于上述移动终端的信息上报的触发方法，其流程包括：步骤S31、步骤S32和步骤S33。
在步骤S31中，终端确定质量门限的第一门限和第二门限，其中，第一门限大于第二门限。
在步骤S32中，终端测量被监控的参考信号的质量值。
在步骤S33中，在质量值大于第二门限且小于第一门限的情况下，终端根据附加条件判断承载参考信号的波束是否发生失效，其中，在波束发生失效的情况下，终端触发第二信息的上报。
通过上述步骤，可解决相关技术中不能触发协议高层的链路失效相关流程的技术问题，实现了触发协议高层的链路失效相关流程的功能。
在一实施例中，终端确定质量门限的第一门限和第二门限包括：终端根据与基站的约定或按照基站的配置确定第一门限和第二门限。
在一实施例中，附加条件包括以下至少之一：终端判断是否有在测量区间内检测到DCI信息；终端判断是否存在比波束的质量值高第一阈值的波束；终端判断参考信号在指定频域位置上的质量值是否低于第三阈值；终端判断前一周期测量到的参考信号的质量值与当前周期测量到的参考信号的质量值之间的差值是否大于第二阈值。
(3)方案三
本申请实施例提供了一种运行于上述移动终端的信息上报的触发方法，其流程包括如下步骤S41和步骤S42。
在步骤S41中，终端获取基站配置的多种类型的质量门限。
在步骤S42中，终端根据多种类型的质量门限判断是否需要触发第二信息的上报，其中，第二信息用于指示下行传输信息。
通过上述步骤，可解决相关技术中不能触发协议高层的链路失效相关流程的技术问题，实现了触发协议高层的链路失效相关流程的功能。
在一实施例中，多种类型的质量门限至少包括：参考信号接收功率RSRP和信号与干扰加噪声比SINR。
在一实施例中，RSRP类型的质量门限包括第一门限和小于第一门限的第二门限，其中，终端根据多种类型的质量门限判断是否需要触发第二信息的上报包括：在RSRP低于第二门限的情况下，终端触发第二信息的上报；在RSRP大于第二门限且小于第一门限的情况下，终端根据SINR类型的质量门限来判断是否需要触发第二信息的上报。
在一实施例中，RSRP类型的质量门限可以是一个门限(RSRP门限)，在大于门限的情况下，则需要SINR判断(即终端根据SINR类型的质量门限来判断是否需要触发第二信息的上报)，在小于该门限的情况下，则直接判断失效。
(二)对于上述技术问题2
当终端发现波束失效后，终端需要选择合适的新的波束用于重建链路，此时需要解决以下问题：波束选择对应的测量参考信号资源集合如何确定、终端如何确定波束选择的时间窗口和门限。
波束选择的时间窗口会影响测量的准确性、波束恢复延迟等。过小的窗口可能造成不能测量足够多的波束，也容易造成不能对同一波束的多次发送进行测量，统计不够充分因而造成结果不准确。过大的窗口则会导致波束恢复的延迟明显，影响链路重建速度，造成系统性能的损失。
相关技术中只提及基站会配置参考信号资源、时间窗、门限等。这种方式的缺点是配置不灵活，存在资源效率不高问题。
波束选择对应的测量参考信号资源集合影响下行参考信号开销，以及上行预留的上报资源大小，需要选择合适大小的参考信号资源集合。集合过大会造成开销的浪费，集合过小容易造成不能准确的选到好的波束用于链路恢复。
为了优化参考信号资源利用率，本实施例提供了一种运行于上述移动终端侧或基站侧的信号的选择或发送方法。
(1)对于终端侧
在S51中，终端与基站约定波束的多种失效类型。
如按照波束失效的对应参考信号类型进行定义，例如：包括如下类型A和类型B。
类型A：SS波束失效，CSI-RS波束也失效。
类型B：CSI-RS波束失效，SS波束未失效。
再如按照波束失效的数目来定义，例如：包括如下类型C和类型D。
类型C：部分被监控波束失效。
类型D：所有被监控波束失效。
还可以按照波束失效的严重程度、波束失效的位置等来进行定义。
在一实施例中，波束失效类型也可以描述为传输性能下降类型。
在S52中，终端根据多种失效类型确定用于波束选择的参考信号资源。
在S53中，终端基于参考信号资源进行测量和选择。
在一实施例中，波束是一个笼统的称呼，参考信号会使用波束传输，此时不同的参考信号代表了不同的波束。因此需要解释一下这个事情，在协议中可能是看不到波束这个概念，只有参考信号的概念。不同的参考信号资源索引其实也就是代表了波束索引。还有其它的方式可以来表征波束。
通过上述步骤，可解决相关技术中不能触发协议高层的链路失效相关流程的技术问题，实现了触发协议高层的链路失效相关流程的功能，并优化了参考信号资源利用率。
(2)对于基站侧
在S61中，基站获取波束的失效类型或参考信号激活请求信息。
在S62中，基站根据失效类型或参考信号激活请求信息来确定需要触发的参考信号。
在S63中，基站发送触发的参考信号。
参考信号一般是针对多种类型的波束失效预配置的。在一实施例中，终端发现波束失效后，可以向基站反馈波束失效的类型信息，也可以直接进行参考信号的激活请求。波束失效的类型信息、参考信号激活请求信息之间的关系可以是M对N的，M可以大于N、小于N或者等于N。
波束选择时，候选参考信号资源集合的相关信息(包括类型，集合大小)可以与波束失效beam failure的类型关联。前面提到的CSI-RS波束和SS波束发生失效的不同情况，出现情况1可能是移动或旋转造成波束变化，出现情况2可能是阻塞Blocking。可以分别对应不同的候选参考信号资源集合。以图2和图7为例，可以是下述情况1和情况2。
这里不同的SS假设为不同的虚拟扇区virtual Cell。
情况1：Serving beam(当前使用的波束)，CSI-RS 15波束失效，Serving virtual Cell(当前虚拟扇区)，SS4未失效。
波束选择对应的参考信号类型为CSI-RS；比如为CSI-RS 13-16。如果SS3，SS5和SS4有比较近似的时间延迟，也可以考虑扩展到CSI-RS 11-18。
情况2：serving beam，CSI-RS 15波束失效，Serving virtual Cell，SS4也失效。
波束选择对应的参考信号类型为SS，比如SS1-SS8。
如果与其它SS关联的CSI-RS波束也在发送，且其配置可以被该UE获知，也可以选择CSI-RS波束，或者在CSI-RS和SS混合波束集合中进行选择。
在一实施例中，图7中的“CSI-RS 1-4”标识编号为1至4的CSI-RS，其余以此类推。
(三)对于上述技术问题3
终端需要在上行信道或信号上波束恢复相关的信息，主要分为两种类型的信息：新波束指示信息和UE指示信息。当发送波束失效时，终端上报这些信息，上行链路也可能是断掉的，需要考虑如何保障接收成功率同时不要浪费上 行的资源开销，以及信息及时性等多种问题，需要在上行引入全新的设计。
上报波束恢复信息时，需要考入如何进行发送。主要包括两个方面：发送功率和发送波束。
对于发送功率：目前还没有相关技术方案，可为PUCCH配置有一套专门的功控机制，但是这套功控机制有可能不适合波束恢复请求的发送。需要独立的设计功控。功控方法可以是本实施例中提供的一种信息的上报方法，其流程包括如下步骤S71和S72。
在步骤S71中，确定待反馈的波束或参考信号的指示信息。
在步骤S72中，获取指示信息的上报资源(即用于上行传输的资源)的位置。
在一实施例中，上述方法还可以包括：步骤S73和步骤S74。
在步骤S73中，根据上报资源的位置确定发射功率。
在步骤S74中，按照发射功率在上报资源的位置上报指示信息。
通过上述步骤，可解决相关技术中不能触发协议高层的链路失效相关流程的技术问题，实现了触发协议高层的链路失效相关流程的功能，并优化了功率控制。
在一实施例中，获取指示信息的上报资源的位置包括：根据波束的失效类型确定上报资源的位置。
在一实施例中，根据波束的失效类型确定候选的上报资源的位置包括：在失效类型为CSI-RS失效时，对应于PUCCH所属区域上报；在失效类型为SS失效时，对应PRACH like所属区域上报。
在一实施例中，根据上报资源的位置确定发射功率包括：在上报资源的位置为PRACH Like所属区域时，获取与基站约定的发射功率；在上报资源的位置为PUCCH所属区域时，根据选择和上报的下行参考信号资源确定上行的发射功率。
(四)对于上述技术问题4
终端判断波束失效并发起波束恢复请求后，如上报波束切换请求(t2)后，立刻切到新的波束上进行控制信息的检测。这种方式可能会产生如下的一些问题：测量结果不准确，原波束还能正常工作；原波束在波束恢复过程中信道变好；找到了新的接收波束，质量提升，无需改变原发送波束。
鉴于上述问题，本申请提出了新方法，不切断原有链路，但允许在新链路上进行检测。在本实施例中提供了一种信道的检测方法，其流程包括如下步骤S81至步骤S84。
在步骤S81中，终端上报推荐的波束的指示信息。
在步骤S82中，终端将时域传输资源和频域传输资源中的至少一种划分为多个区域(划分方式是基站配置的或者是预先由二者进行约定的)。
在步骤S83中，终端根据约定的规则获取多个区域对应的控制信道配置。
在步骤S84中，终端根据控制信道配置检测控制信道。
通过上述步骤，可解决相关技术中不能触发协议高层的链路失效相关流程的技术问题。
终端上报新波束(选择的参考信号资源)指示信息。
终端按照约定的规则将时域和频域传输资源中的至少一种划分为多个区域。
终端根据约定的规则，确定多个资源区域对应的控制信道配置。
其中至少存在一个区域对应原控制信道配置，以及一个区域根据终端上报的新波束(选择的参考信号资源)指示信息确定对应的控制信道配置。
当上报多个新波束(选择的参考信号资源)指示信息时，存在多个区域，其控制对应的控制信道配置分别根据多个新波束(选择的参考信号资源)指示信息确定。
终端在多个资源集合内分别按照其对应的控制信道配置检测控制信道。
一种简单的方式是在时域划分多个区域。
区域1：奇数编号的符号或Slot，区域2：偶数编号的符号或Slot。
终端在区域1内检测控制信道时，按照原来的控制信道配置进行检测。
终端在区域2内检测控制信道时，按照新的控制信道配置进行检测。新的控制信道配置可以根据上报的新波束(选择的参考信号资源)信息来确定。
当终端检测到原来波束上或新波束对应的控制信道资源内传输的DCI信息，则会认为是波束恢复的响应，认为结束波束恢复结束。主要是在以下几种情况下提高波束恢复成功率。
波束测量的结果不准确，不能正确的反映控制信道的质量。
在波束恢复期间Blocking的链路被恢复；在波束恢复期间通过调整接收波束能够正确的在原控制信道上收到DCI；基站在原波束、新波束的控制信道均 能发送DCI，有更大的机会正确的检测到控制信息。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
实施例2
波束失效的判断会明显地影响波束恢复发起的概率，过小的触发概率容易影响波束恢复性能，而过大的触发概率则会引起不必要的波束恢复，造成一些资源浪费和传输效率的降低。相关技术并没有具体的优化方案。本申请可通过一个简单的门限来判断波束是否失效。
终端测量波束质量信息，如果波束质量高于该门限，则判断为波束未失效，无需上报信息给基站，如果波束质量低于该门限，在判断为波束失效，需要进行波束恢复。这种方式面临准确性的问题，因为测量结果往往会受到干扰的影响，还会面临参考信号的统计不充分影响。而且波束参考信号的质量也不能完全的反映控制或数据信道传输的质量。基于此，本申请还提出了以下一些方案来提高波束失效判断的准确性。
(1)方案一
本申请实施例还提供了一种信息上报的触发装置，该装置设置为实现上述实施例及应用实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
本申请实施例提供了一种信息上报的触发装置，该装置包括：第一上报单元。
第一上报单元，设置为向基站上报第一信息，其中：第一信息用于推荐质量门限的配置；质量门限用于终端判断是否需要触发第二信息的上报，第二信息用于指示下行传输信息。
通过上述单元，终端向基站发送第一信息，第一信息用于推荐质量门限的配置，质量门限用于终端判断是否需要触发第二信息的上报，第二信息用于指示下行传输信息，解决了相关技术中不能触发协议高层的链路失效相关流程的技术问题，实现了触发协议高层的链路失效相关流程的功能。
在一实施例中，第二信息指示的下行传输信息包括以下至少之一：终端的终端标识的指示信息、参考信号的指示信息、波束的指示信息、波束恢复的请求信息、参考信号发送的请求信息、以及波束质量的指示信息。
在一实施例中，可由基站直接配置门限值，但由于考虑到每个UE的接收机能力不同，对于相同的RSRP或SINR及码率参数，可能会有不同的接收性能。有的终端通过接收端干扰处理的算法可以非常好的利用接收端多天线处理掉干扰，明显提升SINR。因此用户终端UE根据接收机来推荐门限参数可以用于基站更准确配置波束恢复质量门限，在波束恢复的性能和资源效率之间获得比较好平衡。
