Description

一种覆盖等级指示信息上报方法、装置和用户设备 技术领域
本公开实施例涉及但不限于窄带物联网通信技术，尤其涉及一种覆盖等级指示信息上报方法、装置、用户设备和计算机存储介质，可以应用于终端侧。
背景技术
窄带物联网(Narrow Band Internet of Things，NB-IoT)是万物互联网络的一个重要分支；为了满足终端侧在低功耗和低成本方面的极致需求，NB-IoT的协议规范相比长期演进(Long Term Evolution，LTE)和LTE-A(LTE-Advanced)进行了较大幅度的简化，包括取消了上行链路发送的信道质量指示(Channel Quality Indication，CQI)信息。一方面，网络侧在确定覆盖等级时，主要依据终端侧所上报的覆盖等级指示信息；另一方面，按照协议规范的要求，终端侧在确定覆盖等级指示信息时，参考依据为自身所评估的参考信号接收功率(Reference Signal Receiving Power，RSRP)值。
也就是说，在相关技术中，终端侧在确定和上报覆盖等级指示信息时，仅仅以自身所评估的RSRP值为依据，终端所评估的RSRP值仅能反映小区覆盖信号的强弱，无法反映信号质量的好坏，导致网络侧在进行资源分配与调度时所选择的物理资源承载和重复发送次数，无法与终端侧的实际数据接收性能达到最佳匹配。
发明内容
本公开实施例提供了一种覆盖等级指示信息上报方法、装置、用户设备和计算机存储介质，能够使网络侧在进行资源分配与调度时所选择的物理资源承载和重复发送次数，与终端侧的实际数据接收性能达到最佳匹配
为达到上述目的，本公开实施例的技术方案是这样实现的：
本公开实施例提供了一种覆盖等级指示信息上报方法，所述方法包括：
获取参考信号的测量值；将所述参考信号的测量值与M个覆盖等级对应的测量门限值进行比较，得出第一比较结果，根据所述第一比较结果确定覆盖等级指示信息的基础上报值，M为大于或等于1的整数；
获取小区覆盖信号的质量评估值；
根据所述小区覆盖信号的质量评估值，对所述覆盖等级指示信息的基础上报值进行修正，得到覆盖等级指示信息的修正值；将所述修正值上报。
本公开实施例还提供了一种覆盖等级指示信息上报装置，所述装置包括：第一处理单元、获取单元和第二处理单元，其中，
第一处理单元，设置为获取参考信号的测量值；将所述参考信号的测量值与M个覆盖等级对应的测量门限值进行比较，得出第一比较结果，根据所述第一比较结果确定覆盖等级指示信息的基础上报值，M为大于或等于1的整数；
获取单元，设置为获取小区覆盖信号的质量评估值；
第二处理单元，设置为根据所述小区覆盖信号的质量评估值，对所述覆盖等级指示信息的基础上报值进行修正，得到覆盖等级指示信息的修正值；将所述修正值上报。
本公开实施例还提供了另一种覆盖等级指示信息上报装置，所述装置包括：处理器和设置为存储能够在处理器上运行的计算机程序的存储器；其中，
所述处理器设置为运行所述计算机程序时，执行上述任意一种覆盖等级指示信息上报方法的步骤。
本公开实施例还提供了一种用户设备，包括上述任意一种覆盖等级指示信息上报装置。
本公开实施例还提供了一种计算机存储介质，其上存储有计算机程序，该计算机程序被处理器执行时实现上述任意一种覆盖等级指示信息上报 方法的步骤。
本公开实施例提供的一种覆盖等级指示信息上报方法、装置、用户设备和计算机存储介质中，获取参考信号的测量值；将所述参考信号的测量值与M个覆盖等级对应的测量门限值进行比较，得出第一比较结果，根据所述第一比较结果确定覆盖等级指示信息的基础上报值，M为大于或等于1的整数；获取小区覆盖信号的质量评估值；根据所述小区覆盖信号的质量评估值，对所述覆盖等级指示信息的基础上报值进行修正，得到覆盖等级指示信息的修正值；将所述修正值上报。如此，由于可以根据小区覆盖信号的质量评估值，对覆盖等级指示信息的基础上报值进行修正，因而，网络侧接收到的覆盖等级指示信息可以反映小区覆盖信号的质量，进而，能够使网络侧在进行资源分配与调度时所选择的物理资源承载和重复发送次数，与终端侧的实际数据接收性能达到最佳匹配。

具体实施方式
以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
NB-IoT聚焦于低功耗广覆盖(Low Power Wide Area，LPWA)物联网市场，是一种可在全球范围内广泛应用的新兴技术；NB-IoT基于蜂窝网络构建，具有广覆盖、大容量、低功耗以及低成本等优势；使用的授权频段仅占用200KHz带宽，可以采取in-band、guard-band或者stand-alone三 种部署方式；与现有全球移动通信***(Global System For Mobile Communications，GSM)网络、通用移动通信***(Universal Mobile Telecommunications System，UMTS)网络或者LTE网络共存，以降低部署成本，实现平滑升级。
NB-IoT可以广泛应用于多种垂直行业，如远程抄表、资产跟踪、智能停车及智慧农业等，对于NB-IoT而言，小区覆盖信号强度更加复杂多变，一般分为四种覆盖等级(Coverage Enhancement，CE)：普通覆盖、中等覆盖、弱覆盖和极限覆盖；以《中国电信物联网NB-IoT模块测试方法-数据性能分册》为例，按照RSRP值给出小区覆盖强度参数表：普通覆盖对应的RSRP值为-112dBm，中等覆盖对应的RSRP值为-122dBm，弱覆盖对应的RSRP值为-132dBm，极限覆盖对应的RSRP值小于-132dBm。
在不同的覆盖等级下，网络侧所使用的资源分配方式和调度策略存在很大差异，例如：在普通覆盖场景下，网络侧下发大小为680的最大传输块时，可能使用最少的物理资源(3个物理子帧)；在弱覆盖场景下，网络侧下发大小为680的最大传输块时，可能使用最多的物理资源(10个物理子帧)；在极限覆盖场景下，甚至会考虑进一步增加数据的重复发送次数，以匹配终端侧的数据接收性能要求，由此所付出的代价则是数据传输时延的显著增大。
网络侧在确定覆盖等级时，主要依据终端侧所上报的覆盖等级指示信息，没有其他的上报信息可以作为参考；终端侧在确定覆盖等级指示信息时，参考依据为自身所评估的RSRP值。
然而，RSRP值仅能反映小区覆盖信号的强弱，无法反映信号质量的高低，典型地，当存在强同频干扰信号时，可能存在小区覆盖信号较强且小区覆盖信号的质量较低的情况，此时，如果终端侧仅依据RSRP值上报了“普通覆盖等级”指示，而网络侧也按照“普通覆盖等级”进行资源分配与调度，则物理资源承载和重复发送次数无法与终端侧在强同频干扰条件下的数据接收性能相匹配，物理层和数据链路层将出现大量的数据重传， 不仅严重影响数据吞吐率和传输时延，而且可能由于数据拥塞而导致链路异常。
综上，在相关技术中，终端侧在确定和上报覆盖等级指示信息时，依据的是自身所评估的RSRP值，仅能反映小区覆盖信号的强弱，无法反映信号质量的好坏，导致网络侧在进行资源分配与调度时所选择的物理资源承载和重复发送次数，无法与终端侧的实际数据接收性能达到最佳匹配。
针对上述问题，本公开实施例提出了一种覆盖等级指示信息上报方法、装置、用户设备和计算机存储介质，可以用于终端侧；在实际实施时，终端侧可以根据信道质量辅助信息，确定并向网络侧上报覆盖等级指示信息。
基于上述记载的内容，提出以下各实施例：
第一实施例
本公开第一实施例提出了一种覆盖等级指示信息上报方法。
图1为本公开实施例的覆盖等级指示信息上报方法的流程图一，如图1所示，该流程可以包括：
步骤101：获取参考信号(Narrowband Reference Signal，NRS)的测量值；将所述参考信号的测量值与M个覆盖等级对应的测量门限值进行比较，得出第一比较结果，根据所述第一比较结果确定覆盖等级指示信息的基础上报值，M为大于或等于1的整数。
在实际应用中，用户设备可以在初始随机接入之前，启动参考信号的测量，从而获得参考信号的测量值；图2为本公开实施例的覆盖等级指示信息上报方法的流程图二，示例性地，结合图2，可以启动N个子帧的参考信号测量，N为大于或者等于1的整数，N的典型取值为：1、2、4、8、16、32、64、128、256、512、1024或者2048。
参考信号的测量值用于表示小区覆盖信号的强弱，示例性地，参考信号的测量值可以包括RSRP值。
在实际实施时，M个覆盖等级对应的测量门限值可以是由高层信令配置的门限值。
结合图2，在比较器1中，可以实现参考信号的测量值与M个覆盖等级对应的测量门限值进行比较，然后得出第一比较结果，根据所述第一比较结果确定覆盖等级指示信息的基础上报值CE_basic；基础上报值CE_basic被发送至比较器2中。
步骤102：获取小区覆盖信号的质量评估值。
实际应用中，还可以通过对参考信号的测量，获得参考信号的质量评估值；示例性地，参考信号的质量评估值为参考信号的信噪比SNR NRS。
可选地，还获取小区公共信道的信号质量评估值(例如可以通过小区公共信道的信噪比计算得出)；示例性地，小区公共信道包括但不限于：主同步信号(Narrowband Primary Synchronization Signal，NPSS)、辅同步信号(Narrowband Secondary Synchronization Signal，NSSS)、窄带物理广播信道(Narrowband Physical Broadcast Channel，NPBCH)、承载***信息块(System Information Block，SIB)信息的窄带物理下行共享信道(Narrowband Physical Downlink Shared Channel，NPDSCH)、承载***信息(System Information，SI)的NPDSCH；本公开实施例中，NPSS的信噪比记为SNR NPSS，NSSS的信噪比记为SNR NSSS，NPBCH的信噪比记为SNR NPBCH，承载SIB信息的NPDSCH的信噪比记为SNR NPDSCH-1，承载SI的NPDSCH的信噪比记为SNR NPDSCH-2。
对于获取小区覆盖信号的质量评估值的实现方式，在一个示例中，可以对参考信号的质量评估值、以及小区公共信道的信号质量评估值进行加权求和，得到小区覆盖信号的质量评估值；在另一个示例中，可以将参考信号的质量评估值或小区公共信道的信号质量评估值作为小区覆盖信号的质量评估值。
结合图2，可以根据参考信号的质量评估值和小区公共信道的信号质量评估值进行平均信噪比计算，即，对参考信号的质量评估值、以及小区 公共信道的信号质量评估值进行加权求和，得到小区覆盖信号的质量评估值SNR AVG。小区覆盖信号的质量评估值SNR AVG被发送至比较器2。
步骤103：根据所述小区覆盖信号的质量评估值，对所述覆盖等级指示信息的基础上报值进行修正，得到覆盖等级指示信息的修正值；将所述修正值上报。
作为一种实现方式，可以将所述小区覆盖信号的质量评估值与M个覆盖等级对应的平均信噪比门限值进行比较，得出第二比较结果；根据所述第二比较结果对所述覆盖等级指示信息的基础上报值进行修正，得到覆盖等级指示信息的修正值。
本公开实施例中，可以预先设置M个覆盖等级对应的平均信噪比门限值，。
图2中，平均信噪比门限值表示预先设置的M个覆盖等级对应的平均信噪比门限值；参照图2，可以将平均信噪比门限值输入至比较器2中；然后，在比较器2中，对小区覆盖信号的质量评估值与M个覆盖等级对应的平均信噪比门限值进行比较，得出第二比较结果；根据第二比较结果对所述覆盖等级指示信息的基础上报值进行修正，得到覆盖等级指示信息的修正值CE_report；最后，可以将覆盖等级指示信息的修正值CE_report上报至网络侧。
示例性地，当M大于1时，M个覆盖等级对应的测量门限值包括：从大到小依次排列的第1测量门限值至第M测量门限值，例如，M等于4时，M个覆盖等级对应的测量门限值从大到小依次为：RSRP_TH_CE0、RSRP_TH_CE1、RSRP_TH_CE2和RSRP_TH_CE3。
M个覆盖等级对应的平均信噪比门限值包括：从大到小依次排列的第1平均信噪比门限值至第M平均信噪比门限值；例如，在M等于4时，M个覆盖等级对应的平均信噪比门限值从大到小依次为SNR_TH_CE0、SNR_TH_CE1、SNR_TH_CE2和SNR_TH_CE3。
下面示例性地说明对所述覆盖等级指示信息的基础上报值进行修正 的一种实现方式。
参考信号的测量值大于或等于第1测量门限值，且所述小区覆盖信号的质量评估值大于或等于第1平均信噪比门限值时，将覆盖等级指示信息的修正值确定为所述基础上报值；
所述参考信号的测量值大于或等于第1测量门限值，且所述小区覆盖信号的质量评估值小于第1平均信噪比门限值时，将覆盖等级指示信息的修正值确定为第2覆盖等级；
令i取大于1且小于M的整数，所述参考信号的测量值大于或等于第i测量门限值，且所述参考信号的测量值小于第i-1测量门限值，且所述小区覆盖信号的质量评估值大于或等于第i平均信噪比门限值时，将覆盖等级指示信息的修正值确定为所述基础上报值；
所述参考信号的测量值大于或等于第i测量门限值，且所述参考信号的测量值小于第i-1测量门限值，且所述小区覆盖信号的质量评估值小于第i平均信噪比门限值时，将覆盖等级指示信息的修正值确定为第i+1覆盖等级；
所述参考信号的测量值大于或等于第N测量门限值，且所述参考信号的测量值小于第N-1测量门限值，且所述小区覆盖信号的质量评估值大于或等于第N平均信噪比门限值时，将覆盖等级指示信息的修正值确定为所述基础上报值；
所述参考信号的测量值大于或等于第N测量门限值，且所述参考信号的测量值小于第N-1测量门限值，且所述小区覆盖信号的质量评估值小于第N平均信噪比门限值时，将覆盖等级指示信息的修正值确定为第N覆盖等级；
所述参考信号的测量值小于等于第N测量门限值时，将覆盖等级指示信息的修正值确定为所述基础上报值。
实际应用中，步骤101至步骤103可以由用户设备中的处理器实现，上述处理器可以为特定用途集成电路(Application Specific Integrated  Circuit，ASIC)、数字信号处理器(Digital Signal Processor，DSP)、数字信号处理装置(Digital Signal Processing Device，DSPD)、可编程逻辑装置(Programmable Logic Device，PLD)、现场可编程门阵列(Field Programmable Gate Array，FPGA)、中央处理器(Central Processing Unit，CPU)、控制器、微控制器、微处理器中的至少一种。
可以看出，采用本公开实施例的技术方案时，由于可以根据小区覆盖信号的质量评估值，对覆盖等级指示信息的基础上报值进行修正，因而，网络侧接收到的覆盖等级指示信息可以反映小区覆盖信号的质量，进而，能够使网络侧在进行资源分配与调度时所选择的物理资源承载和重复发送次数，与终端侧的实际数据接收性能达到最佳匹配。
