Description

资源的选择方法及装置
本申请要求在2018年5月11日提交中国专利局、申请号为201810450405.3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
本公开涉及通信领域，具体而言，涉及一种资源的选择方法及装置。
背景技术
随着无线电技术的不断进步，多种多样的无线电业务大量涌现，而无线电业务所依托的频谱资源是有限的，面对人们对带宽需求的不断增加，传统的商业通信主要使用的300MHz～3GHz之间频谱资源表现出极为紧张的局面，已经无法满足未来无线通信的需求。
在未来无线通信中，将会扩展支持比***(4G)通信***所采用的载波频率更高的载波频率进行通信，比如28GHz、45GHz等等，***潜在工作频段达到100GHz。在高频段(大于6GHz)，由于电磁波的衰减很大，通常需要波束赋形的方法来抵抗信号的衰减，提升信号的传输距离。因此，信号通常以波束的形式进行发送或接收。通常情况下，网络侧会为UE配置一个或者多个质量较好的波束来进行通信。并且由于波束的信号质量会一直发生变化，因此配置的波束也要不断变化，使得UE所使用波束信号质量一直能够满足通信需求。
为了保证正常的通信，用户设备(user equipment，简称UE)需要周期性的检测当前链路的质量，物理层根据测量结果周期性地向高层发送同步(In sync，简称IS)指示或失步(Out of sync，简称OOS)指示，以便高层知道当前UE所处的状态。通常情况下，网络侧会配置一组特定的参考信号用于UE测量信号质量。当网络侧没有配置特定的参考信号时，UE使用网络侧配置的物理下行控制信道(Physical downlink control channel，简称PDCCH)的传输配置指示状态(Transmission configuration indicator state，简称TCI state)中指示的参考信号(Reference Signal，简称RS)用于无线链路检测(radio link monitoring，简称RLM)。而TCI state中最多可以指示两个RS。由于UE可以同时激活多个TCI state， 如果UE检测这多个TCI state中的所有RS，会带来大量的测量复杂度和功耗问题。另外，有的RS并不适合用于RLM。因此，如何选择合适的RS用于RLM，是一个极需解决的问题。
发明内容

根据本公开的另一个实施例，提供了一种资源的选择装置，包括：第一接收模块，设置为接收网络侧设备配置的下行链路的传输配置指示状态TCI state；其中，所述TCI state至少包括：多个QCL信息，多个QCL信息中至少包括：参考信号RS以及所述RS对应的QCL类型；选择模块，设置为根据多个QCL信息中的所述RS和/或所述QCL类型选择用于进行无线链路检测RLM的RS。

需要说明的是，本公开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。
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中执行。以运行在移动终端上为例，图1是本公开实施例的一种资源的选择方法的移动终端的硬件结构框图。如图1所示，移动终端10可以包括一个或多个(图1中仅示出一个)处理器102(处理器102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)和用于存储数据的存储器104，可选地，上述移动终端还可以包括用于通信功能的传输设备106以及输入输出设备108。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述移动终端的结构造成限定。例如，移动终端10还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
存储器104可用于存储计算机程序，例如，应用软件的软件程序以及模块，如本公开实施例中的资源的选择方法对应的计算机程序，处理器102通过运行存储在存储器104内的计算机程序，从而执行一种或多种功能应用以及数据处理，即实现上述的方法。存储器104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104可进一步包括相对于处理器102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10。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106用于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10的通信供应商提供的无线网络。在一个实例中，传输装置106包括一个网络适配器(Network Interface Controller，简称为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106可以为射频(Radio Frequency，简称为RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述移动终端的资源的选择方法，图2是根据本公开实施例的一种资源的选择方法的流程图，如图2所示，该流程包括如下步骤：
S202，用户设备UE接收到网络侧设备配置的下行链路的传输配置指示状态TCI state；其中，所述TCI state至少包括：多个QCL信息，多个所述QCL信息中至少包括：参考信号RS以及所述RS对应的QCL类型；
S204，所述UE根据多个所述QCL信息中的所述RS和/或所述QCL类型选择用于进行无线链路检测RLM的RS。
通过本公开，对从网络侧设备发送的TCI state中多个QCL信息中每一个RS以及对应的QCL类型进行甄别，进而可以选择到能够用于RLM的RS。因此，可以解决相关技术中UE因为无法选择合适的RS进行RLM而检测多个TCI state中的所有RS的所带来的大量的测量复杂度和功耗的问题，达到减少UE的测量开销的效果。
可选地，当UE的PDCCH的TCI state中包含多个QCL信息，也就是包含多个RS的时候，UE选择其中的一个RS用于RLM。
可选地，在多个所述QCL信息中还包括：用于标识该TCI state的TCI state ID。
可选地，在移动通信中，处于连接态的UE需要周期性的检测、评估下行链路的信号质量，UE的物理层根据评估结果向高层发送IS指示或者OOS指示。网络侧可以为UE配置多个RS用于UE检测，UE对这些RS分别作测量、滤波、 评估，当所有RS的信号质量都小于一个阈值的时候，物理层向高层上报OOS指示；当至少有一个RS的信号质量大于一个阈值的时候，物理层上高层上报IS指示。该过程也称为无线链路检测。
可选地，所述RS的类型至少包括以下其中之一：同步信号/物理广播信道块(synchronization signal/Physical Broadcast Channel block，SS/PBCH block),信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，跟踪信号(Tracking Reference Signal,TRS)。
可选地，所述QCL类型至少包括以下其中之一：携带有多普勒频移Doppler shift,多普勒扩展Doppler spread,平均延迟average delay,以及延迟扩展delay spread的第一QCL类型；携带有Doppler shift和Doppler spread的第二QCL类型；携带有average delay和Doppler shift的第三QCL类型；携带有空间接收参数Spatial Rx parameter的第四QCL类型。
需要说明的是，如果两个RS具有QCL关系，并且QCL类型为第一QCL类型，那么对于UE的接收来说，这两个RS具有相同或者相似的Doppler shift,Doppler spread,average delay,delay spread，也就是说UE检测到这两个RS的Doppler shift,Doppler spread,average delay,delay spread相同或者相似。如果两个RS具有QCL关系，并且QCL类型为第二QCL类型，那么对于UE的接收来说，这两个RS具有相同或者相似的Doppler shift,Doppler spread，也就是说UE检测到这两个RS的Doppler shift,Doppler spread相同或者相似。如果两个RS具有QCL关系，并且QCL类型为第三QCL类型，那么对于UE的接收来说，这两个RS具有相同或者相似的average delay,Doppler shift，也就是说UE检测到这两个RS的average delay,Doppler shift相同或者相似。如果两个RS具有QCL关系，并且QCL类型为第四QCL类型，那么对于UE的接收来说，UE检测到这两个RS具有相同或者相近的空间方向，或者这两个RS的发送波束方向相同或者相近。如果两个RS具有QCL关系，并且QCL类型为上述QCL类型的多个，那么在UE看来，这两个RS同时满足这多个QCL类型的特征。
可选地，所述UE接收所述网络侧设备配置的多个带宽部分(bandwidth part，简称BWP)，其中，多个所述带宽部分BWP是由所述网络侧设备通过对***带宽分成多个部分获得；所述UE在所述网络侧设备配置的多个所述BWP中激活 的一个或者多个BWP上接收所述网络侧设备发送的信号或者向所述网络侧设备发送信号。
需要说明的是，为了更好的方便UE的接收网络侧的信号和发送信号，通常网络侧可以把***带宽分成多个部分，每个带宽部分称为一个BWP。网络侧可以同时给UE配置多个BWP，并且激活其中的一个或者多个BWP，UE只在激活的下行BWP上接收网络侧发送的信号和激活的上行BWP上发送信号。
可选地，所述UE选择多个所述QCL信息中的一个位于激活的所述BWP内的所述RS进行RLM；或，所述UE选择多个所述QCL信息中多个位于激活的所述BWP内的所述RS作为候补RS，其中所述候补RS具备进行RLM的能力。
具体地，在网络侧设备与用户设备间收发信号(例如RS)的数目很少的情况下，为了避免资源浪费，网络侧设备有可能只分配给UE一个激活的BWP用于信号的收发。因此，当UE接收到网络侧设备在TCI state中包括的QCL信息时，UE会首先检测是否QCL信息中的RS对应的BWP是否激活。如果激活，说明该RS能够实现在网络侧设备与用户设备间收发，因此有必要进行RLM。故而UE会选择该对应激活的BWP的RS进行RLM。
具体地，网络侧设备有可能只分配给UE多个激活的BWP用于RS的收发。当UE接收到网络侧设备在TCI state中包括的QCL信息时，UE会首先检测是否QCL信息中的RS对应的BWP是否激活。如果激活，说明该RS能够实现在网络侧设备与用户设备间收发，因此有必要进行RLM。但考虑到检测多个RS过程中会产生测量复杂度和功耗的等问题，因此进行RLM的RS只能有一个。因此，UE会向将多个QCL信息中对应激活的BWP的RS作为候补RS，需要通过其他的条件进行筛选。
可选地，当所述UE选择多个所述QCL信息中多个位于激活的所述BWP内的所述RS作为所述候补RS时，所述UE根据多个所述QCL信息中的所述RS的信息和/或所述QCL类型选择用于进行所述RLM的RS，还包括：所述UE对多个所述候补RS对应的激活的所述BWP的优先级顺序进行配置，或，所述UE获取由所述网络侧设备配置的激活的所述BWP的优先级顺序，或，所述UE获取协议规定的激活的所述BWP的优先级顺序；所述UE根据所述激活的所述 BWP的优先级顺序选择优先级最高的激活的所述BWP对应的RS进行RLM。
具体地，协议规定的BWP的优先级顺序为：BWP1(第一个激活的BWP)>BWP2(第二个激活的BWP)>BWP3(第三个激活的BWP)>BWP4(第四个激活的BWP)>……>BWPn(第n个激活的BWP，n为正整数)。
可选地，所述UE对所述QCL类型的优先级顺序进行配置，或，所述UE获取由所述网络侧设备配置的所述QCL类型的优先级顺序，或，所述UE获取协议规定的所述QCL类型的优先级顺序；所述UE根据所述QCL类型的优先级顺序选择优先级最高的所述QCL类型对应的RS进行RLM。
具体地，协议规定的QCL类型的优先级顺序为：第四QCL类型>第三QCL类型>第二QCL类型>第一QCL类型。
可选地，所述UE对所述RS对应的RS类型的优先级顺序进行配置，或，所述UE获取由所述网络侧设备配置的所述RS对应的RS类型的优先级顺序，或，所述UE获取协议规定的所述RS对应的RS类型的优先级顺序；所述UE根据所述RS类型的优先级顺序选择优先级最高的所述RS进行RLM。
具体地，协议规定的RS类型的优先级顺序为：CSI-RS>SSB>TRS。
所述UE对所述QCL类型和所述RS对应的RS类型的组合优先级顺序进行配置，或，所述UE获取由所述网络侧设备配置的所述QCL类型和所述RS对应的RS类型的组合优先级顺序，或，所述UE获取协议规定的所述QCL类型和所述RS对应的RS类型的组合优先级顺序；所述UE根据所述组合中的组合优先级顺序选择组合优先级最高的所述RS进行RLM。
具体地，协议规定的所述组合优先级可以通过如下表1中的顺序来确定。需要说明的是，优先级按照0-11，由高到低进行排列。

需要说明的是，为了方便理解本实施中上述内容，在本实施中还提供了以下场景便于理解本实施例中所记载的技术方案：
需要说明的是，为了方便举例，在下述场景当中，默认了UE采用协议规定的优先级顺序进行排序。当然，UE配置的优先级顺序或者网络侧设备配置的优先级顺序进行排序的方法也在本实施例的保护范围之内，在此并不做过多赘述。
场景1
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，2个QCL信息。在第一个QCL信息中包括RS1以及第一QCL类型。在第二个QCL信息中包括RS2和第二QCL类型。
UE对接收到的2个QCL信息中的QCL类型的优先级进行判断。从而确定第二个QCL信息中的QCL类型的优先级要大于第一个QCL信息中的QCL类型的优先级。因此，UE选择第二个QCL信息中包括的RS进行RLM。
场景2
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，3个QCL信息。在第一个QCL信息中包括RS1以及第二QCL类型和第四QCL类型。在第二个QCL信息中包括RS2和第三QCL类型。在第三个QCL信息中包括RS3，第一QCL类型以及第二QCL类型。
UE对接收到的3个QCL信息中的QCL类型的优先级进行判断。从而确定第一个QCL信息中包括了优先级最高的第四QCL类型，而在第二QCL信息中包括的第三QCL类型，以及第三QCL信息中包括的第一QCL类型以及第二QCL类型的优先级程度均要小于第一个QCL信息中的第四QCL类型。因此，UE选择第一个QCL信息中包括的RS进行RLM。
场景3
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，2个QCL信息。在第一个QCL信息中包括SSB以及第二QCL类型。在第二个QCL信息中包括CSI-RS和第二QCL类型。
UE对接收到的2个QCL信息中的RS类型进行判断。从而确定第二个QCL信息中的RS类型CSI-RS的优先级要大于第一个QCL信息中的RS类型SSB的优先级。因此，UE选择第二个QCL信息中包括的RS进行RLM。
场景4
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，两个QCL信息。在第一个QCL信息中包括SSB以及第二QCL类型。在第二个QCL信息中包括CSI-RS和第四QCL类型。
UE同时考虑RS类型和QCL类型来选择RS进行RLM，UE通过调用上述表1中的组合优先级顺序，确定第二个QCL信息中RS类型和QCL类型的的组合优先级最高，而第一个QCL信息中RS类型和QCL类型的组合优先级要小于第二QCL信息的组合优先级。因此，UE选择第二个QCL信息中包括的RS进行RLM。
场景5
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，两个QCL信息。在第一个QCL信息中包括TRS以及第一QCL类型。在第二个QCL信息中包括CSI-RS1和第三QCL类型。
UE同时考虑RS类型和QCL类型来选择RS进行RLM，UE通过调用上述表1中的优先级顺序，确定第一个QCL信息中RS类型和QCL类型的的组合优先级要大于第一个QCL信息中RS类型和QCL类型的组合优先级。因此，UE选择第一个QCL信息，而不是根据第二个QCL信息中包括的RS进行RLM。
场景6
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，多个QCL信息。UE接收到网络侧设备分配的BWP中只有一个BWP被激活。而其他BWP没有被激活。在第一个QCL信息中包括的RS1 位于激活的BWP内。而第二个QCL信息中包括的RS2位于去激活的BWP内。
UE通过获取网络侧设备分发的多个BWP以及多个QCL的信息确定，只有第一个QCL信息中的RS1在激活的BWP内。因此，UE选择唯一一个位于激活的BWP的RS1进行RLM。
场景7
UE接收到网络侧设备配置的PDCCH的TCI state。其中在该TCI state中包括：TCI state ID，三个QCL信息。UE接收到网络侧设备分配的BWP中只有一个BWP被激活。而其他BWP没有被激活。在第一个QCL信息中RS1和第一个QCL信息的RS2在激活的BWP内。而第三个QCL信息中包括RS3在去激活的BWP内。同时，在第一个QCL信息中包括RS1以及第一QCL类型。在第二个QCL信息中包括RS2和第二QCL类型。
UE通过获取网络侧设备分发的多个BWP以及多个QCL的信息确定，第一个QCL信息中的RS1和第二个QCL信息中的RS2均在激活的BWP内。无法确定哪一个QCL信息中的RS用于RLM。因此，UE将第一个QCL信息中的RS1和第二个QCL信息中的RS2作为用于RLM的候选RS进行后续进一步的筛选。
UE此时需要对接收到的2个QCL信息中的QCL类型进行判断。从而确定第二个QCL信息中的第二QCL类型的优先级要大于第一个QCL信息中的第一QCL类型。因此，UE选择第二个QCL信息中包括的RS进行RLM。
场景8
UE接收到网络侧设备配置的PDSCH的TCI state。其中在该TCI state中包括：TCI state ID，四个QCL信息。UE接收到网络侧设备分配的BWP中有BWP1，BWP2和BWP3被激活，而其他的BWP则没有被激活。
在第一个QCL信息中包括：位于激活的BWP3内的CSI-RS以及第一QCL类型。在第二个QCL信息中包括：位于激活的BWP1内的TRS以及第二QCL类型。在第三个QCL信息中包括：位于激活的BWP1内的SSB以及第三个QCL类型。在第四个QCL信息中包括：位于去激活的BWP内的CSI-RS以及第四个QCL类型。
UE通过获取网络侧设备分发的多个BWP以及多个QCL的信息确定，在第二个QCL信息中TRS和第三个QCL信息中SSB对应的激活的BWP的优先级相同，大于第一QCL信息中CSI-RS对应的激活的BWP3。同时，第四个QCL信息中的CSI–RS位于去激活的BWP。因此，UE将第二个QCL信息中TRS和第三个QCL信息中SSB作为用于RLM的候选RS。
第一个QCL信息中的RS1和第二个QCL信息中的RS2均在激活的BWP内。无法确定哪一个QCL信息中的RS用于RLM。因此，UE将第一个QCL信息中的RS1和第二个QCL信息中的RS2作为用于RLM的候选RS进行后续进一步的筛选。
UE通过调用上述表1中的优先级顺序，确定第二个QCL信息中RS类型和QCL类型的组合优先级要大于第三个QCL信息中RS类型和QCL类型的组合优先级。因此，UE选择第二个QCL信息，而不是根据第三个QCL信息中包括的RS进行RLM。
需要说明的是，上述具体并非穷举。任何基于本公开思路的选择方案均在本实施例的保护范围以内。
