资源选择方法、装置及用户设备
相关申请的交叉引用
本申请主张在2020年04月16日在中国提交的中国专利申请号202010302326.5的优先权，其全部内容通过引用包含于此。
技术领域
本申请涉及通信技术领域，尤其涉及一种资源选择方法、装置及用户设备。
背景技术
目前，新空口(New Radio，NR)sidelink(旁链路)中支持抢占的机制。例如，在Mode 2资源分配模式中，资源pre-emption机制被支持，即，当一个UE的预留资源和其它具有更高优先级业务的UE的预留的资源重叠(如，部分重叠)，且这些UE在相关资源上的SL-RSRP测量值大于某个associated SL-RSRP门限值时，低优先级业务的UE会触发资源的重新选择。
如此，在引入行人UE(PUE)后，抢占机制会导致进行资源选择的终端设备抢占PUE的资源，从而导致PUE的性能下降。例如，在NR V2X中，需要支持PUE与车UE(VUE)之间的通信，若PUE和VUE采用相同的资源池，且该资源池支持抢占机制，那么VUE抢占PUE的资源或者PUE抢占PUE的资源，会导致被抢占资源的PUE的性能下降，从而可能导致系统中PUE发送的数据包的性能下降。
发明内容
本申请实施例提供一种资源选择方法、装置及用户设备，以解决PUE在支持抢占机制的场景下，所存在的PUE性能下降的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，本申请实施例提供了一种资源选择方法，应用于UE，该方法包括：满足预定条件时，根据资源选择窗口内的第一资源的资源信息，确定备选资源集；从备选资源集中选择目标资源；其中，上述预定条件包括以下至少一项：上述UE检测到第一类型UE的预留资源，上述UE为第一类型UE；上述资源信息包括以下至少一项：优先级信息，测量结果，测量门限，第一资源所属UE的UE类型。
第二方面，本申请实施例提供了一种资源选择装置，包括：确定模块，用于满足预定条件时，根据资源选择窗口内的第一资源的资源信息，确定备选资源集；选择模块，用于从确定模块确定的备选资源集中选择目标资源；其中，上述预定条件包括以下至少一项：UE检测到第一类型UE的预留资源，上述UE为第一类型UE；上述资源信息包括以下至少一项：优先级信息，测量结果，测量门限，第一资源所属UE的UE类型。
第三方面，本申请实施例提供了一种UE，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面所述的资源选择方法的步骤。
第四方面，本申请实施例提供一种计算机可读存储介质，所述计算机可读存储介质上存储计算机程序，所述计算机程序被处理器执行时实现如第一方面所述的资源选择方法的步骤。
在本申请实施例中，UE在检测到第一类型UE的预留资源和/或该UE为第一类型UE的情况下，可以根据资源选择窗口内的第一资源的资源信息，来确定出备选资源集，然后从该备选资源集中选择目标资源。如此，使得第一类型UE在支持抢占机制或第一类型UE检测到被抢占时，可以基于资源选择窗口内的第一资源的资源信息进行资源选择或重选，不仅降低了第一类型UE的资源被抢占的概率，也避免了第一类型UE频繁的进行资源重选，从而降低了第一类型UE的能量开销以及性能损失，进而达到省电的目的。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下将对本申请实施例涉及的技术术语进行解释说明。
1、旁链路(sidelink)
LTE系统支持sidelink，用于UE之间不通过网络设备进行直接数据传输，即UE之间直接在空口进行数据传输。该数据传输是以广播形式进行的。旁链路也可以称之为副链路、侧链路或边链路。
需要说明的是，sidelink虽然可用于支持车(vehicle to everything，V2X)的基本安全类通信，但不适用于其他更高级的V2X业务。5G NR(New Radio)系统将支持更加先进的sidelink传输设计，例如，单播，多播或组播等，从而可以支持更全面的业务类型。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或V2X通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格QoS需求的高级V2X业务将通过NR sidelink支持。
其中，在NR V2X中支持V2V的通信。
2、sidelink资源分配
LTE sidelink设计支持两种资源分配模式，分别是调度资源分配(Scheduled resource allocation)模式与自主资源选择(autonomous resource selection)模式。前者 由网络侧设备控制并为每个UE分配资源，后者由UE自主选择资源。其中，LTE sidelink mode 1为D2D的调度资源分配模式，LTE sidelink mode 2为D2D的自主资源分配模式；LTE sidelink mode 3为V2X的调度资源分配模式，LTE sidelink mode 4为V2X的自主资源分配模式。
其中，LTE sidelink mode 4的基本工作原理如下：
在检测窗(sensing window)内进行测量，在每个检测TTI内解调度分配(scheduling assignment，SA)及进行干扰测量。具体的，UE根据以下步骤进行资源选择：
1)排除UE发送数据的资源。
2)终端解调收到的SA，得到其他UE的预留资源，排除其他UE的预留资源。
3)在sensing window内进行能量检测，测量参考信号强度指示(reference signal strength indication，RSSI)，根据测量结果，排除干扰大的资源。
4)在sensing window内，从干扰最小的20％的资源中随机选择一个子帧(subframe)进行周期的资源预留。
此外，NR V2X定义了两种资源分配mode，一种是mode1，为基站调度资源；另一种是mode2，UE自己决定使用什么资源进行传输。此时，该资源信息可能来自基站的广播消息或者预配置的信息。UE如果工作在基站范围内并且与基站有RRC连接，可以是mode1和/或mode2，UE如果工作在基站范围内但与基站没有无线资源控制(Radio Resource Control，RRC)连接，只能工作在mode2。如果UE在基站范围外，那么只能工作在mode2，根据预配置的信息来进行V2X传输。
对于NR V2X中的mode 2，其基本工作原理如下：
1)TX UE在资源选择流程被触发后，首先确定资源选择窗口(其中，该资源选择窗口的下边界在资源选择流程被触发后的T1时间，该资源选择窗口的上边界在资源选择流程被触发后的T2时间，T2是UE在其TB传输的数据时延(packet delay budget，PDB)内选择的值，T2不早于T1)。
2)UE在资源选择的之前，需要确定资源选择的备选资源集(candidate resource set)，根据资源选择窗口内的资源对应测量的RSRP与相应的RSRP阈值(即RSRP threshold)做对比，如果RSRP高于RSRP threshold，则认为该资源被排除，也就是如果RSRP低于RSRP threshold，那么该资源可以纳入备选资源集。其中，上述资源选择窗口内的资源对应测量的RSRP为UE在调度该资源的SCI信息所在的时隙中测量所得的值，如，可以是测量SCI(或者说，物理旁链路控制信道(Pysical Sidelink Control Channel，PSCCH))，或者是，测量SCI所在时隙中调度的物理旁链路共享信道(Pysical Sidelink Share Channel，PSSCH)所获取的值。
3)备选资源集确定后，UE随机在备选资源集中选择资源。
另外，UE在本次传输可以为接下来的传输预留传输资源。且NR V2X支持链式的资源预留方式，也就是，一个旁链路控制信息(Sidelink Control Information，SCI)可以预留当前的资源，最多可以在额外预留两个资源，在下一个资源中，可以再指示两个预留资源。在资源选择窗内，还可以采用动态预留的方式持续预留资源。
3、部分检测(Partial sensing)
LTE V2X中部分检测主要是为了省电而设计的，是为了支持P2V的通信，PUE 支持两种模式的资源选择方式。一种为随机的资源选择；另一种模式为先进行部分检测，基于部分检测的结果选择资源，进行半静态的资源预留。其中，PUE选择哪种模式为RRC配置的，当RRC配置为支持两种模式的资源选择时，PUE实现决定采用哪种资源选择方式。
具体地，终端进行部分检测并进行资源检测的方式如下：
其中，如图1所示，PUE检测窗口为在[n-1000,n]的范围内的窗口。在选择窗口内的[n+T1,n+T2]内的窗口A为高层配置的PUE的选择窗口。PUE在检测窗口B中检测其他终端发送的SCI，根据检测的SCI以及预留周期，推测其他终端在窗口A内的资源预留情况，该PUE可以根据这些信息排除选择窗口中不满足条件的资源。在剩余的资源中选择至少20％(窗长的20％)的资源作为候选资源集合，上报给MAC层，MAC层从候选资源集合中随机选择一个资源作为该PUE的候选资源。该PUE对选择的资源进行周期预留，预留周期在SCI中指示。
4、sidelink抢占(Pre-emption)机制
在Mode 2中，资源pre-emption机制被支持。一个UE已经预留的资源和其它具有更高优先级业务的UE所预留的资源重叠(部分重叠)，并且这些UE在相关资源上的SL-RSRP测量值大于某个associated SL-RSRP门限值时，低优先级业务的UE会触发资源的重新选择。这里的associated SL-RSRP门限值可以是一个预定义或者基站预配置的固定的RSRP门限。该固定值可以基于UE自身待传输业务(即当前TB)的优先级、PDB、业务类型、QoS、可靠性等信息与SL-RSRP门限值的映射关系确定确定门限值X。
5、其他术语
需要说明的是，本文中的“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
需要说明的是，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能或作用基本相同的相同项或相似项进行区分，本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。例如，第一预设规则和第二预设规则是用于区别不同的预设规则，而不是用于描述预设规则的特定顺序。
需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
需要说明的是，本申请实施例中，“的(英文：of)”，“相应的(英文：corresponding，relevant)”和“对应的(英文：corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。本申请实施例中的“多个”的含义是指两个或两个以上。
本申请实施例提供的资源选择方法执行主体可以为资源选择装置，也可以为终端设备。其中，上述的资源选择装置可以为终端设备，也可以为该终端设备中能够实现 该资源选择方法的功能模块和/或功能实体，具体的可以根据实际使用需求确定，本发明实施例不作限定。
本申请实施例提供的资源选择方法适用于引入Mode 2机制PUE时的资源选择场景，还适用于PUE选择资源进行发送的场景，例如，P2V的场景或者P2P的场景，还可以适用于当检测到PUE预留的资源时，其他终端(例如：PUE，或者VUE)如何进行资源选择的场景，也可以说，可以适用于支持P2V的资源池或者是支持V2P的资源池中一种选择机制的资源选择场景。
本申请提供的技术方案可以应用于各种通信系统，例如，5G通信系统，未来演进系统或者多种通信融合系统等等。可以包括多种应用场景，例如，机器对机器(Machine to Machine，M2M)、D2M、宏微通信、增强型移动互联网(enhance Mobile Broadband，eMBB)、超高可靠性与超低时延通信(ultra Reliable&Low Latency Communication，uRLLC)以及海量物联网通信(Massive Machine Type Communication，mMTC)等场景。这些场景包括但不限于：终端设备与终端设备之间的通信，或网络设备与网络设备之间的通信，或网络设备与终端设备间的通信等场景中。本申请实施例可以应用于与5G通信系统中的网络设备与终端设备之间的通信，或终端设备与终端设备之间的通信，或网络设备与网络设备之间的通信。

下面将以UE为例，对本发明实施例提供的资源选择方法进行示例性的说明。
图3示出了本申请实施例提供的一种资源选择方法的流程示意图，如图3所示，该资源选择方法可以包括步骤201和步骤202：
步骤201：UE在满足预定条件时，根据资源选择窗口内的第一资源的资源信息，确定备选资源集。
步骤202：UE从备选资源集中选择目标资源。
其中，上述预定条件包括以下至少一项：UE检测到第一类型UE的预留资源，UE为第一类型UE；上述资源信息包括以下至少一项：优先级信息，测量结果，测量门限，第一资源所属UE的UE类型。
在本申请实施例中，在UE检测到第一类型UE的预留资源的情况下，上述第一资源包括第一类型UE的预留资源。
可以理解，上述预定条件可以包括以下至少一项：UE检测到第一类型UE的预留资源，UE的部分检测机制使能。
在本申请实施例中，当UE的部分检测机制使能，则表明该UE为第一类型UE。在UE为第一类型UE时(也可以理解为，当部分检测机制使能时)，即第一类型UE执行资源选择方案时，上述第一资源可以包括第一类型UE的预留资源，也可以不包括第一类型UE的预留资源，本申请实施例对此不做限定。
在本申请实施例中，上述测量结果可以包括测量值。示例性的，上述第一资源对应的测量值可以包括：参考信号接收功率(Reference Signal Received Power，RSRP)，接收信号强度指示(Received Signal Strength Indicator，RSSI)，参考信号接收质量(Reference Signal Received Quality，RSRQ)，信干噪比(Signal-to-noise and Interference Ratio，SINR)，信噪比(Signal noise ratio,SNR)，误块率(Block Error ratio,BLER)。
可选地，本申请实施例中的第一类型UE可以为PUE，第二类型UE可以为VUE。
可选地，上述第一资源可以为SCI或DCI中指示的资源，也可以是指示的周期的资源，也可以是指示的非周期的资源，本申请实施例对此不作限定。
可选地，在本申请实施例中，上述资源信息还包括使能信息，上述使能信息用于指示上述UE的部分检测机制是否使能。
可选地，在本申请实施例中，在上述资源信息包括第一资源所属UE的UE类型的情况下，UE可以基于上述资源信息以及预定排除规则，排除目标UE类型的预留资源。其中，上述预定排除规则包括排除目标UE类型的预留资源；上述的目标UE类型可以为上述第一类型(如，PUE)。
可选地，在本申请实施例中，UE在获取资源选择窗口内的第一资源的资源信息之前，会在资源检测窗口中接收到至少一个第一UE对应的SCI。其中，每个第一UE对应的SCI中携带优先级信息；上述第一资源包括上述至少一个第一UE中的每个第一 UE在资源选择窗口中的预留资源。可以理解，上述的优先级信息包括上述至少一个第一UE中的每个第一UE对应SCI中携带的优先级信息。
应注意的是，本申请实施例中UE的预留资源，可以理解为UE预留的资源，也可以理解为UE占用的资源，本申请实施例对此不作限定。例如，PUE的预留资源可以称为PUE占用的资源；同理，VUE的预留资源可以称为VUE占用的资源。
本申请实施例中的UE至少可以通过三种实现方式来确定备选资源。
第一种可能的实现方式(提高第一类型UE的优先级)
具体的，本申请实施例可以通过提高第一类型UE的优先级，从而使得UE在进行资源排除时，可以将该第一类型UE的预留资源认为是被占用的资源，进而可以优先排除第一类型UE的预留资源，减少该第一类型UE的预留资源被抢占的概率。
可选地，在本申请实施例中，上述优先级信息用于指示：第一类型UE的优先级最高，和/或，第一类型UE的预留资源的优先级最高。
示例性的，在上述UE为第一类型UE的情况下，上述优先级信息用于指示该UE的优先级最高。如此，其他UE便无法占用该第一类型UE的预留资源。
示例性的，当VUE在进行资源抢占时，若检测到PUE的预留资源，VUE认为该预留资源不能被占用(也就是排除PUE的预留资源)。当然，也可以认为是排除PUE的占用资源。
可选地，在本申请实施例中，上述第一类型UE的优先级是按照第一预设规则设置的；其中，上述第一预设规则包括以下至少一项：
设置上述第一类型UE的优先级大于或等于上述UE传输的数据包的优先级，
按照预设优先级偏移值设置上述第一类型UE的优先级，
上述第一类型UE的优先级位于预设优先级范围内。
示例性的，UE可以按照以下至少一种方式设置或获取第一类型UE的优先级：1、定义第一类型UE的优先级偏移值；2、定义第一类型UE的优先级的取值范围。
示例性的，上述第一类型UE的优先级可以为该第一类型UE的预留资源的优先级，也可以为该第一类型UE传输的数据包的优先级。在一种示例中，可以设置该PUE的预留资源的优先级，使得该PUE的预留资源的优先级高于其他传输的数据包的优先级，或者，使得该PUE的预留资源的优先级位于较高的优先级范围内(例如，限制PUE的优先级需要小于预定优先级)。
需要说明的是，上述第一预设规则适用于：所有配置了P2V或者V2P的资源池，或者，配置了该第一预设规则的资源池(例如，若某一资源池中配置了第一预设规则，就认为这个资源池需要使用这个规则)。
进一步的，在某一资源池中是否采用该第一预设规则进行第一类型UE优先级的映射，可以显式指示(如，1bit指示这个第一的预设规则在这个资源池中是否采用，如果为1，表示该资源池需要根据这个规则来进行优先级设置；如果为0，表示该资源池需要根据其他规则进行优先级设置，而不采用这个规则)，也可以隐式指示。
进一步可选地，在本申请实施例中，上述预设优先级偏移值与上述UE的信道忙率(channel busy ratio，CBR)(如，CBR的范围)相关；或者，上述预设优先级偏移值是预定义的或高层信令配置的或下行控制信息(Downlink Control Information，DCI) 指示的或旁链路控制信息SCI指示的；或者，上述预设优先级范围的下门限是预定义的或高层信令配置的或DCI指示的或SCI指示的。
针对上述第一预设规则包括按照预设优先级偏移值设置上述第一类型UE的优先级的场景。
例1：RRC可以为每个CBR range配置对应的P_delta值(即上述预设优先级偏移值)。当CBR大于CBR门限值，则P_delta为0，否则，P_delta采用配置的值。其中，CBR门限值为协议预定义/网络配置/预配置的值。
例2：UE可以根据第二类型UE的优先级规则获取P_pri，第一类型UE的优先级为P_pri+P_delta。其中，第二类型UE的优先级规则可以包括：从SCI中获取优先级，或者，从高层信令获取优先级。
第二种可能的实现方式(优先排除第一类型UE的预留资源)
可选地，在本申请实施例中，上述第一资源包括：上述第一类型UE的预留资源和第二类型UE的预留资源。上述步骤201可以包括如下步骤201a：
步骤201a：在上述第一类型UE的预留资源的优先级与上述第二类型UE的预留资源的优先级相同的情况下，UE排除上述第一类型UE的预留资源。
示例性的，当UE检测到PUE的预留资源和VUE的预留资源时，若PUE的预留资源与VUE的预留资源的优先级相同，则优先排除PUE的预留资源。
示例性的，假设PUE的优先级被配置为最高优先级，VUE的优先级可以设置的比PUE的优先级低，也可能存在被配置为最高优先级的情况。例如，优先级从高到低为0-7，VUE优先级可以存在0-7的配置，若PUE的优先级和VUE的优先级均设置为0，则此时可以直接排除PUE的预留资源。
示例性的，UE可以以优先级为一级分类进行第一次排除，再以UE类型为第二级分类，在同类优先级中进行排除。
示例性的，以为VUE为例，VUE基于优先级进行资源排除，再基于UE类型进行资源排除。也就是，VUE可以抢占资源池中VUE的预留资源，若资源数目不满足需求，则再抢占PUE的预留资源。具体的，可以根据PUE的优先级进行资源抢占。
可选地，在本申请实施例中，上述步骤201可以包括如下步骤：
步骤A1：若检测到任一第一资源对应的参考测量值大于或等于目标测量门限，则UE排除该任一资源。
示例性的，以测量值为RSRP为例，UE测量PUE的RSRP和/或PUE测量RSRP时，采用以下方式。如，UE测量PUE的RSRP的结果为RSRP_real，在进行资源排除时，可以通过提高PUE的预留资源的参考RSRP测量值，来减少PUE所占用的资源被该UE选择的概率。例如，将提高后的参考RSRP测量值(如，RSRP_real+RSRP_delta)与RSRP门限进行比较。其中，上述RSRP_delta为协议预定义/预配置/配置的值，或者，RSRP_delta的值与CBR相关。
可选地，在本申请实施例中，在上述测量结果包括参考测量值的情况下，本申请实施例提供的资源选择方法还可以包括如下步骤：
步骤A2：UE配置上述第一类型UE的检测参数。
其中，上述检测参数包括以下至少一项：目标测量门限的第二预设规则，参考测 量值的第三预设规则，测量门限偏移值，测量偏移值。
示例性的，本申请实施例可以通过定义或配置UE优先级与目标测量门限的关系，来优先排除第一类型UE的预留资源。例如，提高测量门限，提高量为beta_threshold例如提高测量值，提高量为beta，上述beta值和beta_threshold值可以为协议预定义，或者RRC预配置，或者RRC/MAC CE配置，或者DCI/SCI指示的值。
在一种示例中，以测量值为RSRP为例，若根据第一协议版本(如R16)定义的优先级与RSRP门限值的映射规则得到RSRP门限值为RSRP_th，则UE在进行资源排除时，可以基于RSRP门限值RSRP_th-beta判断该第一类型UE的资源是否被排除。
进一步可选地，在本申请实施例中，当任一第一资源为第一类型UE的预留资源时，上述第二预设规则包括：基于第一原始测量门限和第一测量门限偏移值设置目标测量门限；或者，当上述UE为第一类型UE时，上述第二预设规则包括：基于第二原始测量门限和第二测量门限偏移值设置目标测量门限。应注意的是，上述第一测量门限偏移值和第二测量门限偏移值可以为正值，也可以为负值，本申请实施例对此不做限定。
示例性的，上述基于第一原始测量门限和第一测量门限偏移值设置目标测量门限可以包括：在上述第一原始测量门限的基础上减去或加上第一测量门限偏移值，得到目标测量门限。
示例性的，基于第二原始测量门限和第二测量门限偏移值设置目标测量门限可以包括：在第二原始测量门限的基础上加上或减去第二测量门限偏移值得到目标测量门限。
示例性的，上述的原始测量门限是基于UE的优先级、预留资源对应的优先级的优先级参数，查找RRC对应的表格，从而确定出的。如，上述的第一原始测量门限是基于UE的优先级以及第一类型UE的预留资源对应的优先级通过查表得到的。
示例性的，UE在进行资源排除时，可以根据以下至少一种方式获取使用的RSRP threshold(即上述目标测量门限)。方式1：当测量第一类型UE的占用资源时，认为RSRP threshold的值为获取的RSRP threshold(即原始测量门限)减去第一测量门限偏移值。方式2：当第一类型UE测量时，认为RSRP threshold的值为获取的RSRP threshold(即原始测量门限)加上第二测量门限偏移值。
示例性的，上述第一测量门限偏移值是预定义的或协议规定的或预配置的或第一载体配置的或第一指示信息指示的；和/或，上述第一测量门限偏移值与UE的CBR相关。其中，上述第一载体包括RRC或MAC CE；上述第一指示信息包括：DCI或SCI。
示例性的，上述第二测量门限偏移值是预定义的或协议规定的或预配置的或第二载体配置的或第二指示信息指示的；和/或，上述第二测量门限偏移值与UE的CBR相关。其中，上述第二载体包括RRC或MAC CE；上述第二指示信息包括：DCI或SCI。
进一步可选地，在本申请实施例中，当任一第一资源为上述第一类型UE的预留资源时，上述第三预设规则包括：基于上述第一类型UE的预留资源对应的测量值和第一测量偏移值，得到上述第一类型UE的预留资源对应的参考测量值；或者，当上 述UE为第一类型UE时，上述第三预设规则包括：基于任一第一资源对应的测量值和第二测量偏移值，得到上述任一第一资源对应的参考测量值。应注意的是，上述第一测量偏移值和第二测量偏移值可以为正值，也可以为负值，本申请实施例对此不做限定。
示例性的，上述基于上述第一类型UE的预留资源对应的测量值和第一测量偏移值得到第一类型UE的预留资源对应的参考测量值可以包括：在上述第一类型UE的预留资源对应的测量值的基础上加上或减去第一测量偏移值，得到上述第一类型UE的预留资源对应的参考测量值。
