无线链路的测量方法及装置、终端、基站、存储介质
相关申请的交叉引用
本申请基于申请号为201711148886.4、申请日为2017年11月17日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域但不限于通信领域，尤其涉及一种无线链路的测量方法及装置、终端、基站、存储介质。
背景技术
随着无线电技术的不断进步，各种各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，将会扩展支持比第四代(4G)通信系统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，系统潜在工作频段达到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，基站会为终端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，使得终端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，终端(user equipment，简称UE)需要周期性的 检测当前链路的质量，根据测量结果周期性地向高层发送指示，以便高层知道当前终端所处的状态。比如，当信号的质量大于某一个阈值时，终端的物理层向高层上报同步(in sync，简称为IS)；当信号的质量小于某一个阈值时，终端向高层上报失步(out of sync，简称为OOS)。由于终端与基站存在多种可用的波束，因此基站会配置多个参考信号资源用于终端检测其链路质量。当配置的参考信号的资源数越来越多时，终端每次需要检测的信号越多，从而导致其测量无线链路的复杂度和功耗也会随之增加。

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。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本申请实施例中，提供了一种无线链路的测量方法。图1是根据本申请实施例的一种可选的无线链路的测量方法的流程图。如图1所示，无线链路的测量方法的一种可选流程包括：
步骤S101，终端接收下行参考信号的配置信息，其中，配置信息包括以下至少之一：配置参数的信息，不同配置参数之间的耦合关系；
步骤S103，终端根据配置信息进行无线链路的测量。
通过上述方案，终端接收下行参考信号的配置信息，其中，配置信息包括以下至少之一：配置参数的信息，不同配置参数之间的耦合关系，然后终端根据配置信息进行无线链路的测量，解决了相关技术中，由于基站配置多个参考信号资源用于终端检测其链路质量，导致终端测量无线链路的复杂度和功耗随之增加的问题。上述方案有效降低了终端测量无线链路的复杂度和功耗，同时不会增加终端宣告无线链路失败的延迟，提高了终端对无线链路的测量效率。
需要说明的是，终端和基站之间还可以通过协议预先约定好配置参数之间的耦合关系是怎样的，基站向终端发送配置信息的时候，只需要下发下行参考信号在一种情况下的至少一个配置参数信息，其他情况下的配置参数信息，终端可以根据耦合关系自行获取。此处的不同情况可以理解为基站下发不同的下行参考信号资源数的情况。
在本申请实施例的一个优选方案中，上述步骤S103可以通过以下步骤实现：终端根据配置信息在第一无线链路上检测下行参考信号；终端的高层根据检测结果确定是否宣告第一无线链路失败。

在本申请实施例的一个优选方案中，上述终端的高层根据检测结果确定是否宣告第一无线链路失败，可以通过以下步骤实现：终端的物理层根据下行参考信号的检测结果向终端的高层发送同步IS指示或失步OOS指示，其中，当检测到的下行参考信号中至少有一个信号质量大于预设阈值时，发送IS指示，当检测到的下行参考信号中全部的信号质量均小于预设阈值时，发送OOS指示；当终端的高层接收到第一预设数量(N1)的OOS指示或在第一预设时间内接收到的全部都是OOS指示时，启动定时器；若终端的高层在定时器预设的时间内接收到的IS指示的数量达到第二预设数量(N2)，停止定时器的计时；若终端的高层在定时器预设的时间内接收到的IS指示的数量未达到第二预设数量，宣告第一无线链路失败。
在本申请实施例的一个优选方案中，配置参数至少包括以下之一：终端测量下行参考信号的测量周期TM，IS指示的评估周期Tin，OOS指示的评估周期Toos，用于启动定时器的OOS指示的第一预设数量N1，用于停止定时器的IS指示的第二预设数量N2，下行参考信号的发送周期T以及下行参考信号的资源数N，其中，下行参考信号的资源数N与以下至少之一具有耦合关系：终端测量下行参考信号的测量周期TM，IS指示的评估周期Tin，OOS指示的评估周期Toos，用于启动定时器的OOS指示的第一预设数量N1，用于停止定时器的IS指示的第二预设数量N2，下行参考信号 的发送周期T。在本申请实施例的一个优选方案中，耦合关系包括：当下行参考信号的资源数N越大时，终端测量下行参考信号的测量周期TM越大，IS指示的评估周期Tin和OOS指示的评估周期Toos越大，用于启动定时器的OOS指示的第一预设数量N1和用于停止定时器的IS指示的第二预设数量N2越小，下行参考信号的发送周期T越大。反之，当下行参考信号的资源数N越小时，终端测量下行参考信号的测量周期TM越小，IS指示的评估周期Tin和OOS指示的评估周期Toos越小，用于启动定时器的OOS指示的第一预设数量N1和用于停止定时器的IS指示的第二预设数量N2越大，下行参考信号的发送周期T越小。

在本申请实施例的一个优选方案中，在第一无线链路的检测过程中，当下行参考信号的资源数N发生变化时，终端可以根据N的变化重新确定与下行参考信号的资源数N具有耦合关系的其他配置参数的数值。
在本申请实施例的一个优选方案中，上述终端根据N的变化重新确定与所述下行参考信号的资源数N具有耦合关系的其他配置参数的数值，可以通过以下步骤实现：终端的高层根据耦合关系重新确定用于启动定时器的OOS指示的第一预设数量N1和用于停止定时器的IS指示的第二预设数量N2，并根据耦合关系自动更改已经收到的OOS指示的个数或已经收到的IS指示的个数。具体的举例说明见后续的优选实施例。

为了更好地理解本申请的技术方案，本申请实施例通过以下具体实施方式来进行进一步的说明。
在移动通信系统中，UE需要周期性地测量下行参考信号，并根据测量结果对当前的链路质量作评估。通常情况下，UE获得一个测量结果之后，在作链路质量评估之前，需要对测量结果作过滤(filtering)，然后将过滤后的测量结果用于链路质量评估。假设UE按照时间顺序的测量结果依次为M0,M1,M2,...,一种可能的过滤的方法为
F n＝(1-a)·F n-1+a·M n
其中，Mn为最新的测量结果，Fn为滤波后的结果，Fn用于无线链路质量评估，Fn-1为前一次滤波的结果，也就是Mn-1的滤波结果，并且F0＝M0，a为过滤系数，是一个配置的常数。
UE检测的下行参考信号为周期性发送的信号，比如周期性发送的同步信号块(Synchronization signal block，简称为SS block)或者信道状态信息参考信号(Channel state information reference signal，简称为CSI-RS)，在本申请实施例中该下行参考信号统称为无线链路检测参数信号(Radio link monitoring reference signal，简称为RLM-RS)。网络侧可以配置一个或者多个RLM-RS资源用于UE检测，那么在一个测量时刻，UE可以获得一个或者多个测量结果Mn(每个RLM-RS资源得到一个测量结果)，通过上 述的过滤公式，可以得到一个或多个过滤后的结果Fn。在UE检测的RLM-RS资源中，有一个RLM-RS资源的信号质量大于阈值Q_in，也就是有一个Fn的值大于Q_in，UE物理层向高层上报IS指示。当所有RLM-RS资源的信号质量都小于Q_out，也就是所有的Fn的值都小于Q_in，UE物理层向高层上报OOS指示。
UE的用于IS评估的时间长度为Tin，需要说明的是，此处的IS的评估时间长度与前述的IS评估周期可以理解为同一个配置参数。UE评估Tin时间段内的信号质量，每个RLM-RS资源分别得到一个Fn，如果有一个Fn的值大于阈值Q_in，UE物理层向高层上报IS指示。用于OOS评估的时间长度为Toos，需要说明的是，此处的OOS的评估时间长度与前述的OOS评估周期可以理解为同一个配置参数。UE评估Toos时间段内的信号质量，每个RLM-RS资源分别得到一个Fn，如果所有的Fn的值都小于阈值Q_out，UE物理层向高层上报OOS指示。测量周期为TM，表示每隔TM的时间，UE检测配置的RLM-RS资源；IS或者OOS指示上报周期为TI，表示UE每隔TI的时间，UE物理层向高层上报IS或者OOS指示，并且IS或OOS指示上报周期TI的最小值为UE的测量周期TM，IS指示的上报周期TI的最大值为UE的IS评估时间长度Tin，OOS指示的上报周期的最大值为UE的OOS评估时间长度TOOS。图7是根据本申请实施例的一种可选的终端高层宣告发生无线链路失败的示意图。如图7中，通常情况下UE高层连续收到N1个OOS指示之后，启动定时器T1。当定时器T1处于运行状态，在T1时间内，如果UE收到了N2个IS，那么停止计时器T1。如果定时器T1耗尽时，UE仍然没有收到N2个IS，高层宣告发生无线链路失败。
在一些实施例中，UE无线链路失败过程中的参数N1、N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度Toos与配置的RLM-RS的资源数N具有一定的耦合关系。该耦合关系使得当UE配置的RLM-RS资 源数N越大时，N1和N2的值越小，测量周期TM的值越大，IS评估时间长度Tin越大，OOS的评估周期Toos越大；当UE配置的RLM-RS资源数N越小时，N1和N2的值越大，测量周期TM的值越小，IS评估时间长度Tin越小，OOS的评估时间长度Toos越小。此时IS指示的上报周期的最大值为UE的评估时间长度为Tin，最小值为测量周期TM；OOS指示的上报周期最大值为UE的OOS评估时间长度TOOS，最小值为测量周期TM。此时，基站只需要配置一种RLM-RS资源数情况下的N1，N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度TOOS的参数值，其他RLM-RS资源数情况下的参数值UE根据这种耦合关系可以得到。
下面以具体的例子进行详细说明，UE无线链路失败过程中的参数N1、N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度Toos与配置的RLM-RS资源数N的耦合关系为：测量周期TM与RLM-RS资源数N的比值为一个定值(成正比)；IS/OOS评估时间长度内的测量结果个数是一个定值，也就是Tin和Toos与N的比值是一个定值(成正比)；N1和N2与N的乘积是一个定值(成反比)。图8是根据本申请实施例的一种可选的终端高层宣告发生无线链路失败的示意图。假设基站配置RLM-RS资源数为1时的参数为，N1的值为8，N2的值为16，测量周期为10ms，IS评估时间长度为80ms，OOS评估时间长度为160ms。那么当基站给UE配置RLM-RS的资源数为2时，UE根据耦合关系可以得到测量周期为20ms，IS评估时间长度为160ms，OOS评估时间长度为320ms，N1的值为4，N2的值为8。当基站给UE配置的RLM-RS的资源数为4时，UE根据耦合关系可以得到测量周期为40ms，IS评估周期长度为320ms，OOS评估时间长度为640ms，N1的值为2，N2的值为4。此时，不同RLM-RS资源数情况下，UE的无线链路失败的过程如图8中。
另一种可能的实现方式，基站配置的参数为：N1、N2，测量周期TM， IS评估时间长度Tin，OOS评估时间长度TOOS，并且基站给UE配置的RLM-RS的资源数为N，那么UE根据耦合关系可以得到无线链路失败过程中使用的参数为：IS评估时间长度为T in*N，OOS评估时间长度为T oos*N，测量周期为T M*N，UE连续收到

图9是根据本申请实施例的一种可选的终端高层宣告发生无线链路失 败的示意图。如图9所示，UE高层在T2时间段内收到的指示全部为OOS，启动定时器T1。如果定时器T1处于运行状态，高层收到了N2个IS指示，停止定时器T1。当定时器T1耗尽时，宣告发生无线链路失败。
UE无线链路失败过程中的参数N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度Toos与配置的RLM-RS的资源数N具有一定的耦合关系。该耦合关系使得当UE配置的RLM-RS的资源数N越大时，N2的值越小，测量周期TM的值越大，IS评估时间长度Tin越大，OOS的评估周期Toos越大；当UE配置的RLM-RS个数N越小时，N2的值越大，测量周期TM的值越小，IS评估时间长度Tin越小，OOS的评估时间长度Toos越小。此时IS指示的上报周期的最大值为UE的评估时间长度为Tin，最小值为测量周期TM；OOS指示的上报周期最大值为UE的OOS评估周期长度TOOS，最小值为测量周期TM。此时，基站只需要配置一种RLM-RS资源数情况下的N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度TOOS的参数值，其他RLM-RS资源数情况下的参数值UE根据这种耦合关系可以得到。
下面以具体的例子进行详细说明，UE无线链路失败过程中的参数N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度Toos与配置的RLM-RS的资源数N的耦合关系为：测量周期TM与RLM-RS资源数N的比值为一个定值(成正比)；IS/OOS评估时间长度内的测量结果数是一个定值，也就是Tin和Toos与N的比值是一个定值(成正比)；N2与N的乘积是一个定值(成反比)。图10是根据本申请实施例的一种可选的终端高层宣告发生无线链路失败的示意图。如图10所示，基站配置RLM-RS资源数为1时的参数为：N2的值为16，测量周期为10ms，IS评估时间长度为80ms，OOS评估时间长度为160ms。那么当基站给UE配置RLM-RS的资源数为2时，UE根据耦合关系可以得到测量周期为20ms，IS评估时间长 度为160ms，OOS评估时间长度为320ms，N2的值为8。当基站给UE配置的RLM-RS的资源数为4时，UE根据耦合关系可以得到测量周期为40ms，IS评估周期长度为320ms，OOS评估时间长度为640ms，N2的值为4。此时，不同RLM-RS资源数情况下，UE的无线链路失败的过程如图10中。
在前述实施例的基础上描述在无线链路失败过程中RLM-RS资源数发生变化的时候，高层如何处理已收到IS/OOS指示个数。
UE在某一时刻配置的RLM-RS资源数由N变成了M，根据优选实施例一，UE在无线链路失败过程中的参数N1和N2发生变化，假设其数值由N11变成了N12，N21变成了N22，在此之前高层已经收到了X个OOS指示，那么当RLM-RS资源数由N变成M之后，高层认为此前收到OOS的个数为

个IS指示，那么停止定时器T1。
下面以具体的例子进行详细说明，图11是根据本申请实施例的一种可选的终端高层宣告发生无线链路失败的示意图。如图11所示，在t1时刻之前，UE配置的RLM-RS资源数为1，N1的值为8，在t1时刻，UE配置的RLM-RS资源数为2，N1的值为4，此前高层已经收到了4个OOS指示，那么高层根据N1的值的前后变化关系，在t1时刻之后，认为此前收到OOS指示个数为2，如果高层再连续收到2个OOS指示，启动定时器T1。
图12是根据本申请实施例的一种可选的终端高层宣告发生无线链路失败的示意图。如图12所示，在开始阶段，定时器T1处于运行状态，在t2 时刻之前，UE配置的RLM-RS资源数为2，N2的值为8，在t2时刻，UE配置的RLM-RS资源数为1，N2的值为16，此前高层已经收到了3个IS指示，那么高层根据N2值的前后变化关系，在t2时刻之后，认为此前收到的IS指示个数为6，如果高层再连续收到10个IS指示，停止定时器T1。
UE无线链路失败过程中的参数N1、N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度Toos，以及RLM-RS的发送周期与配置的RLM-RS的资源数目N具有一定的耦合关系。该耦合关系使得当UE配置的RLM-RS资源数N越大时，N1和N2的值越小，测量周期TM的值越大，IS评估时间长度Tin越大，OOS的评估周期Toos越大，RLM-RS的发送周期越大；当UE配置的RLM-RS资源数N越小时，N1和N2的值越大，测量周期TM的值越小，IS评估时间长度Tin越小，OOS的评估时间长度Toos越小，RLM-RS的发送周期越小。此时IS指示的上报周期的最大值为UE的评估时间长度为Tin，最小值为测量周期TM；OOS指示的上报周期最大值为UE的OOS评估时间长度TOOS，最小值为测量周期TM。此时，基站只需要配置一种RLM-RS资源数情况下N1，N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度TOOS的参数值，RLM-RS的发送周期，其他RLM-RS数目情况下的参数值UE根据这种耦合关系可以得到。
下面以具体的例子进行详细说明，UE无线链路失败过程中的参数N1、N2，测量周期TM，IS评估时间长度Tin，OOS评估时间长度Toos，RLM-RS的发送周期与配置的RLM-RS资源数N的耦合关系为：测量周期TM与RLM-RS资源数N的比值为一个定值(成正比)；IS/OOS评估时间长度内的测量结果个数是一个定值，也就是Tin和Toos与N的比值是一个定值(成正比)；N1和N2与资源数N的乘积是一个定值(成反比)，RLM-RS的发送周期与资源数N的比值为一个定值(成正比)。图13是根据本申请实施例的一种可选的终端高层宣告发生无线链路失败的示意图。如图13所示， 假设基站配置RLM-RS资源数为1时的参数为，N1的值为8，N2的值为16，测量周期为10ms，RLM-RS发送周期为10ms，IS评估时间长度为80ms，OOS评估时间长度为160ms。那么当基站给UE配置RLM-RS的资源数为2时，UE根据耦合关系可以得到测量周期为20ms，RLM-RS发送周期为20ms，IS评估时间长度为160ms，OOS评估时间长度为320ms，N1的值为4，N2的值为8。当基站给UE配置的RLM-RS的资源数为4时，UE根据耦合关系可以得到测量周期为40ms，RLM-RS发送周期为40ms，IS评估周期长度为320ms，OOS评估时间长度为640ms，N1的值为2，N2的值为4。UE的无线链路失败的过程如图13中。
