Description

一种测量信号传输方法及网络设备 技术领域
本发明涉及通信技术领域，尤其涉及一种测量信号传输方法及网络设备。
背景技术
参考信号(Reference Signal，RS)是由发射端提供给接收端用于信道估计或信道探测的一种已知信号。下行参考信号是由基站提供给用户设备(User Equipment，UE)用于下行信道估计或测量的信号，在下行参考信号中存在小区特定参考信号(Cell-specific Reference Signal，CRS)，可以用来解调下行控制信道，还可以用来做下行信道测量，下行信道测量结果是进行小区选择/重选和切换的关键指标。目前，主要使用CRS来进行下行信道测量。在系统频带上的任意一个物理资源块(Physical Resource Block，PRB)上都分布有CRS，即CRS是一个全频带分布的参考信号。
子系统(例如窄带物联网(Narrow Band–Internet of Thing，NB-IoT))是应用在未来第五代移动通信技术(5G)或新无线接入网技术(New Radio Access Technology，NR)中的一种技术。子系统必须部署在100kHz信道栅格处，如果某个PRB的中心频点或该中心频点的附近一定频率偏移内，满足是100kHz的整数倍，则认为该PRB可以部署子系统。
CRS在整个频带上连续分布，即每个PRB上都有CRS分布，然而部分PRB会被用于部署子系统，这些用于部署子系统的PRB上不希望出现参考信号，因此类似CRS这种全频带分布的参考信号的部署与子系统的部署会彼此影响。

在一种可能实现的方式中，所述资源指示消息为主同步信号PSS，所述PSS的根序列指示部署所述测量信号所占用的所述物理资源块和/或传输所述测量信号所占用的所述物理资源。可以理解的是，不同的根序列指示测量信号不同的部署方式，部署方式由所占用的物理资源块表示。

在一种可能实现的方式中，根据部署子系统所占用的物理资源块确定用于部署测量信号的物理资源块，即避开子系统所占用的物理资源块或减少子系统与测量信号占用相同物理资源块的概率，从而避免或减少测量信号的部署与子系统部署之间的影响。
在一种可能实现的方式中，所述物理资源块包括位置连续的至少两个物理资源块，表示测量信号占用连续的物理资源块。
在一种可能实现的方式中，所述物理资源块包括位置等间隔的至少两个物 理资源块，表示测量信号占用的物理资源块非连续，可以理解为占用的物理资源块的编号成等差数列。

本发明实施例第三方面提供一种计算机存储介质，用于储存为上述网络设备所用的计算机软件指令，其包含用于执行上述方面所设计的程序。
在本发明实施例中，通过确定用于部署测量信号的物理资源块，物理资源块为用户设备的信道带宽对应的频域上的全部物理资源块的子集，并确定物理资源块对应的物理资源，并使用物理资源向用户设备传输测量信号，测量信号用于用户设备测量信道信息，从而避免部署测量信号与部署子系统占用相同的物理资源块，或减少部署测量信号与部署子系统占用相同的物理资源块的概率，进而减少测量信号的部署与子系统部署之间的影响，同时保证测量信号的测量性能。

在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。

此外，本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(Compact Disk，CD)、数字通用盘(Digital Versatile Disk，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(Erasable Programmable Read-Only Memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是本发明实施例提供的一种可能的网络架构示意图。如图1所示，该网络架构100包括网络设备102，网络设备102可包括多个天线例如，天线104、106、108、110、112和114。另外，网络设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个用户设备(例如用户设备116和用户设备122)通信。然而，可以理解，网络设备102可以与类似于用户设备116或122的任意数目的用户设备通信。用户设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA、车载设备和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，用户设备116与天线112和114通信，其中天线112和114通过前向链路118向终端设备116发送信息，并通过反向链路120从用户设备116接收信息。此外，用户设备122与天线104和106通信，其中天线104和106通过前向链路124向用户设备122发送信息，并通过反向链路126从用户设备122接收信息。
应理解，本发明实施例可以应用于下行传输，即网络设备122向用户设备传输测量信号，例如图1中示出的118和124。图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
图1所示的网络设备122还可以为用户设备116或122或其它用户设备配置信道带宽、信道带宽对应的系统资源。其中，信道带宽是指限定了允许通过该信道的信号下限频率和上限频率，也就是限定了一个频率通带。在未来5G通信系统或NR系统中存在子系统的情况下，信道带宽可以为主系统带宽。网络设备122还可以为用户设备116或122配置子载波间隔，根据信道带宽和子载波间隔确定信道带宽对应的系统资源，进而配置信道带宽对应的系统资源。其中，信道带宽对应的系统资源可以为信道带宽对应的频域上的全部物理资源块，即频域上的物理资源块总数。需要说明的是，本发明实施例中所涉及的物理资源块均为频域上的物理资源块。可参见图2，为信道带宽与物理资源块(PRB)个数之间的映射列表，需要说明的是，图2所示的映射列表为子载波间隔为15kHz对应的映射列表，若子载波间隔不为15kHz，则信道带宽与PRB个数的对应与图2有所不同。在蜂窝通信系统或LTE系统中，每个PRB包括 12个子载波。
目前，用于下行信道测量的CRS在系统频带上的任意一个PRB上都有分布，例如信道带宽为3MHz，子载波间隔为15kHz，其对应的15个PRB上均部署着CRS。
在未来5G通信系统或NR系统中，有一些新的设计与需求，对于每个NR子载波，可以支持多种正交频分复用系统设计的基本参数(numerology)。其中，numerology可以包括子载波间隔、循环前缀长度、传输时间间隔长度、信道带宽等。未来5G通信系统或NR系统中的下行子载波间隔为15kHz，或为15kHz的2n倍，例如120kHz、150kHz等。在各种numerology下，可以支持子系统的部署。其中，子系统可以包括但不限于窄带物联网。子系统必须部署在100kHz信道栅格处，如果某个PRB的中心频点或该中心频点附近一定频率偏移内，满足是100kHz的整数倍，则认为该PRB可以部署子系统。
由于每个PRB上都有CRS分布，然而部分PRB会被用于部署子系统，这些用于子系统部署的PRB不希望出现参考信号，因此类似CRS这种全频带分布的参考信号的部署与子系统的部署会彼此影响。
为了避免或减小类似CRS这种全频带分布的参考信号的部署与子系统部署之间的影响，本发明实施例提供一种测量信号以及一种测量信号传输方法，能够避免或减小测量信号的部署对子系统部署的影响，同时保证测量信号的测量性能。其中，所述测量信号用于用户设备测量信道信息，即实现CRS的测量功能，并且所述测量信号具有前向兼容性，即兼容未来5G通信系统或NR系统或未来第六代移动通信技术(6G)等更远的通信系统。但是，所述测量信号并不是全频带分布的参考信号。需要说明的是，所述测量信号的名称并不构成对本发明实施例的限定。本发明实施例还提供一种网络设备，用于实现所述测量信号传输方法。
下面将结合附图3-附图5对本发明实施例提供的测量信号传输方法进行详细介绍。
请参见图3，为本发明实施例提供的一种测量信号传输方法的流程示意图，该方法可以包括：
301，确定用于部署测量信号的物理资源块，所述物理资源块为用户设备的信道带宽对应的频域上的全部物理资源块的子集；
具体的，任意一个网络设备可针对其覆盖范围内的每个用户设备配置信道带宽，在存在子系统的情况下，所述信道带宽可以为主系统带宽。
网络设备针对用户设备配置信道带宽、所述信道带宽对应的系统资源。所述信道带宽对应的系统资源即为所述信道带宽对应的频域上的全部物理资源块。在一种可能实现的方式中，所述网络设备还为所述用户设备配置子载波间隔，根据所述信道带宽以及所述子载波间隔确定所述信道带宽对应的系统资源，进而为所述用户设备配置所述信道带宽对应的系统资源。若所述子载波间隔为15kHz，则所述网络设备可以根据图2所示的信道带宽与PRB个数之间的映射列表为所述用户设备配置所述信道带宽对应的PRB个数。
所述网络设备在配置所述信道带宽以及所述用户设备对应的系统资源的同时或之后，在所述用户设备对应的系统资源中配置用于部署子系统的物理资源块，或用户部署除测量信号、子系统之外的其它信号的物理资源块。下面以部署子系统为例进行介绍。
由于子系统必须部署在100kHz信道栅格处，只有部分满足此条件的PRB可以部署子系统。计算每个PRB的中心频点，如果某个PRB的中心频点或该PRB的中心频点附近一定频率偏移内，满足是100kHz的整数倍，则认为该PRB可以部署子系统。由于未来5G通信系统或NR系统可以支持多种numerology，即支持多种子载波间隔，针对多种子载波间隔，以及多种信道带宽对应的PRB个数，计算得出图4所示的部署子系统的物理资源块对照表。图4所示的对照表描述多种子载波间隔中每种子载波间隔在每种PRB个数下所占用的PRB编号(编号从0开始)。以子载波间隔为15kHz、信道带宽对应的PRB个数为15个为例，由于一个PRB包括12个子载波，那么此时的PRB宽度为180kHz，此时可用于部署子系统的PRB表示为(2；12)，即这15个PRB中编号为2和编号为12的PRB可用于部署子系统。需要说明的是，子系统可在编号为2和编号为12的PRB上同时部署，也可在编号为2和编号为12的其中任意一个PRB上部署，也可在编号为2和编号为12的PRB上都不部署。以子载波间隔为37.5kHz，信道带宽对应的PRB个数为15个为例，此时的PRB宽度为450kHz，此时可用于部署子系统的PRB为(1，3；11，13)，即这15个PRB中编号为1、编号为3、编号为11和编号为13的PRB可用于部署子系统。需要说明的是，子系统可在这四个PRB的一个、多个或全部PRB上部署，也可 以在这四个PRB上都不部署。
所述网络设备可根据图4所示的对照表，结合所述信道带宽以及所述子载波间隔，在所述用户设备对应的系统资源中配置用于部署子系统的物理资源块。所述用于部署子系统的物理资源块可能为零个PRB、一个或多个PRB。
所述网络设备确定用于部署测量信号的物理资源块，所述物理资源块为信道带宽对应的频域上的全部物理资源块的子集。可选的，所述网络设备根据部署子系统所占用的物理资源块确定用于部署测量信号的物理资源，从而避免测量信号的部署与子系统部署占用相同的物理资源块，或减小测量信号的部署与子系统部署占用相同的物理资源块的概率，进而避免或减小彼此之间的影响。
在一种可能实现的方式中，用于部署测量信号的所述物理资源块包括位置连续的至少两个物理资源块。其中，位置连续表示从所述系统资源的最中间向两侧延伸的资源连续，无间隔。位置连续可以理解为PRB编号连续。基于图4所示的部署子系统的物理资源块对照表，归纳、构造可得图5a所示的一种部署测量信号的物理资源块对照表。图5a所示的对照表描述在各个子载波间隔、各种PRB个数下可用于部署测量信号的连续PRB的个数。以子载波间隔为15kHz、信道带宽对应的PRB个数为15个为例，可用于部署测量信号的PRB对应于(9，15)，9表示测量信号可以占用这15个PRB中的从最中间向两侧延伸的连续9个PRB，15表示测量信号可以占用这连续的15个PRB。当子系统占用编号为2和/或编号为12的PRB时，测量信号可以占用从编号3至编号11这9个连续的PRB；当未部署子系统时，测量信号可以占用从编号0至编号14这15个连续的PRB。由于图5a所列的情况较多，复杂度较高，因此基于图5a所示的对照表，提取几种具有代表性的情况，构造可得图5b所示的另一种部署测量信号的物理资源块对照表。图5b中，若信道带宽对应的PRB个数为奇数，则n表示信道带宽对应的PRB中最中间的那个PRB，例如信道带宽对应的PRB个数为15个，最中间的那个PRB为第8个PRB(编号为7的PRB)，可用于部署测量信号的PRB为(n-4,n+4)，表示可用于部署测量信号的PRB为从最中间向两侧延伸的连续的9个PRB，即编号3至编号11这连续的9个PRB。(n-7,n+7)表示可用于部署测量信号的PRB为从最中间向两侧延伸的连续的15个PRB。若信道带宽对应的PRB个数为偶数，则n-，n+表示信道带宽对应的PRB中最中间的两个PRB，例如信道带宽对应的PRB 个数为50个，最中间的两个PRB为第25个(编号为24)和第26个PRB(编号为25的PRB)，可用于部署测量信号的PRB为(n--4,n++4)，表示可用于部署测量信号的PRB为从最中间向两侧延伸的连续的10个PRB，即编号20至编号29这连续的10个PRB。(n--9,n++9)表示可用于部署测量信号的PRB为从最中间向两侧延伸的连续的20个PRB，即编号15至编号34这连续的20个PRB；(n--14,n++14)表示可用于部署测量信号的PRB为从最中间向两侧延伸的连续的30个PRB，编号10至编号39这连续的10个PRB。
请参见图6a，为测量信号连续部署的示意图。图6a以信道带宽对应的PRB个数为15个为例，编号为2的PRB的中心频点为-907.5kHz，编号为12的PRB的中心频点为907.5kHz，频率偏移为±7.5，满足100kHz的整数倍，因此可以在这两个PRB上部署子系统。若在编号为2和编号为12的PRB上部署子系统，即图6a中第一行、第二行横条纹所示的PRB，则测量信号可以部署在编号3至编号11这连续的9个PRB上，即图6a中第二行斜条纹所示的PRB。若这个15个PRB上未部署子系统，则测量信号可以部署在这连续的15个PRB上，即图6a中第三行斜条纹所示的PRB。
在另一种可能实现的方式中，用于部署测量信号的所述物理资源块包括位置等间隔的至少两个物理资源块。其中，位置等间隔可以理解为资PRB编号不连续。基于图4所示的部署子系统的物理资源块对照表，归纳、构造可得图5c所示的又一种部署测量信号的物理资源块对照表。图5c所示的对照表描述在各个子载波间隔、各种PRB个数下可用于部署测量信号的PRB序列。图5c中，k＝0,1,2,...，若信道带宽对应的PRB个数为奇数，则n表示信道带宽对应的PRB中最中间的那个PRB，例如信道带宽对应的PRB个数为15个，最中间的那个PRB为第8个PRB(编号为7的PRB)，可用于部署测量信号的PRB序列为{n+1±2k}，表示可用于部署测量信号的PRB为编号为0、编号为2、编号为4、编号为6、编号为8、编号为10、编号为12、编号为14的PRB；{n±3k}表示可用于部署测量信号的PRB为编号为1、编号为4、编号为7、编号为10、编号为13的PRB。若信道带宽对应的PRB个数为偶数，则n-，n+表示信道带宽对应的PRB中最中间的两个PRB，例如信道带宽对应的PRB个数为50个，最中间的两个PRB为第25个(编号为24)和第26个PRB(编号为25的PRB)，可用于部署测量信号的PRB序列为{n+±3k}，数据较多在 此不一一列举。可以理解的是，对应的PRB序列表示PRB的编号成等差数列，可用于部署测量信号的PRB成等间隔部署(梳状部署)。
请参见图6b，为测量信号等间隔部署的示意图。图6b以信道带宽对应的PRB个数为15个为例，在编号为2和编号为12的PRB上部署子系统，即图6b中第一行、第二行横条纹所示的PRB，根据PRB序列{n±3k}，测量信号可以部署在编号为1、编号为4、编号为7、编号为10、编号为13的PRB上，即图6a中第二行斜条纹所示的PRB。由此可见，测量信号插在子系统之间的PRB上等间隔部署，可以看成是梳状部署。
302，确定所述物理资源块对应的物理资源；
具体的，所述网络设备根据PRB与资源单元(Resource Element，RE)之间的映射关系对用于部署测量信号的所述物理资源块进行映射，并确定映射后的物理资源。其中，所述物理资源用于测量信号的传输。其中，资源单元为物理资源的基本单元。
303，使用所述物理资源向所述用户设备传输测量信号，所述测量信号用于所述用户设备测量信道信息；
具体的，所述网络设备可以在所述物理资源块上部署测量信号之后，使用所述物理资源向所述用户设备传输测量信号，即所述物理资源作为测量信号的载体向所述用户设备传输。
所述网络设备还可以在传输测量信号之前或之后，向所述用户设备发送资源指示消息，所述资源指示消息指示部署所述测量信号所占用的所述物理资源块和/或传输所述测量信号所占用的所述物理资源。通过所述资源指示消息告知所述用户设备哪些物理资源块上部署有测量信号，从而便于所述用户设备在对应的物理资源块上查找测量信号。通过所述资源指示消息告知所述用户设备哪些物理资源用于传输测量信号，从而便于所述用户设备根据物理资源查找对应的物理资源块，从而获取测量信号。所述资源指示消息同时指示所述物理资源块和所述物理资源，便于所述用户设备快速获取测量信号。
需要说明的是，下文中的部署方式即为测量信号占用PRB的方式，可以包括连续占用、等间隔占用。其中，连续占用由连续的PRB数量表示，等间隔占用由等间隔的PRB序列表示。
在一种可能实现的方式中，所述资源指示消息为主同步信号(Primary  Synchronization Channel，PSS)，所述PSS包括根序列，所述根序列指示部署所述测量信号所占用的所述物理资源块和/或传输所述测量信号所占用的所述物理资源。在LTE中，物理层是通过物理小区ID(Physical Cell Identities，PCI)来区分不同的小区的。物理小区ID总共有504个，它们被分成168个不同的组(记为
Figure PCTCN2016099068-appb-000001
范围是0-167)，每个组又包括3个不同的组内标识(记为
Figure PCTCN2016099068-appb-000002
范围是0-2)。因此，物理小区ID(记为
Figure PCTCN2016099068-appb-000003
)可以通过
Figure PCTCN2016099068-appb-000004
公式计算得到。辅同步信号(Secondary Synchronization Signal，SSS)用于传输组内ID，即

PSS用于传输组内ID，即

在一种可能实现的方式中，所述资源指示消息为广播消息，所述广播消息指示部署所述测量信号所占用的所述物理资源块和/或传输所述测量信号所占用的所述物理资源。其中，所述广播消息包括资源指示位，所述资源指示位的数值指示部署所述测量信号所占用的所述物理资源块和/或传输所述测量信号所占用的所述物理资源。其中，所述广播消息可以包括但不限于系统信息块(MasterInformationBlock，MIB)消息。在MIB消息中存在资源指示位，可以用3bits表示所述资源指示位，3bits可以表示8种可能的部署方式，上述两表中分别列举了6种和5种部署方式，那么3bits可以表示上述两表中所列举的部署方式。MIB消息还包括所述网络设备为所述用户设备配置的所述信道带宽以及所述系统资源。所述网络设备可预先定于所述资源指示位的每种数值对应的部署方式，例如001表示±7或+1±2k。MIB消息在物理广播信道(Physical Broadcast Channel，PBCH)上广播给所述用户设备。所述用户设备通过PBCH信道接收MIB消息，并根据资源指示位所指示的数值确定测量信号的部署方式，即部署测量信号所占用的物理资源块或传输测量信号所占用的物理资源。
所述用户设备在接收到所述资源指示信息时，根据所述资源指示信息确定测量信号所占用的PRB，并在相应的PRB上接收所述网络设备传输的测量信号。所述用户设备根据测量信号测量信道信息。所述信道信息包括参考信号接收功率(Reference Signal Recieved 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 Recieved  Quality，RSRQ)中的至少一种。其中，RSRP是用户设备接收到的测量信号或CRS的功率值，数值为测量带宽内单个RE功率的线性平均值，反映的是本小区有用信号的强度。RSSI是用户设备接收到的所有信号(包括同频的有用和干扰、邻频干扰、热噪声等)功率的线性平均值，反映的是该资源上的负载强度。RSRQ是N倍的RSRP与RSSI的比值，RSRQ＝N*RSRP/RSSI，其中N表示RSRI的测量带宽内包含的RE数目，能反映出信号和干扰之间的相对大小。
所述用户设备可根据测量信号测量所述信道信息，还可根据测量信号进行精时频同步。
在本发明实施例中，通过确定用于部署测量信号的物理资源块，物理资源块为用户设备的信道带宽对应的频域上的全部物理资源块的子集，并确定物理资源块对应的物理资源，并使用物理资源向用户设备传输测量信号，测量信号用于用户设备测量信道信息，从而避免部署测量信号与部署子系统占用相同的物理资源块，或减少部署测量信号与部署子系统占用相同的物理资源块的概率，进而减少测量信号的部署与子系统部署之间的影响，同时保证测量信号的测量性能。
