Description

用于小区测量的方法和装置

技术领域
本申请涉及通信领域，并且更具体地，涉及一种用于小区测量的方法和装置。
背景技术
在无线通信系统中，终端设备通常有三种状态，分别是无线资源控制(radio resource control，RRC)连接态(RRC_CONNECTED)和RRC空闲态(RRC_IDLE)、RRC去激活态(RRC_INACTIVE)。当处于空闲态或去激活态时，终端设备无法与网络设备直接进行通信。为了网络设备能够有效地找到空闲态/去激活态的终端设备，网络设备一般会通过寻呼的方式，即定期地向终端设备发送寻呼调度信息，以指示终端设备是否应该从空闲态/去激活态切换至连接态，以便与网络设备进行通信。终端设备在收到寻呼调度信息后可以醒来进入连接态，以便发送或接收业务数据。
处于空闲态/去激活态的终端设备会在某个寻呼周期内醒来监听寻呼消息。终端设备醒来的时刻称为寻呼时机(paging occasion，PO)。网络设备会在该时刻将寻呼消息从空口发出，以便终端设备在该时刻接收到寻呼消息。终端设备监听寻呼消息的行为是需要付出一些功耗的。另外，终端设备还需要在某一时刻醒来做无线资源管理(radio resource management，RRM)测量，这也需要一些功耗的。因此，亟需提出一种方法来节省终端设备的功耗。

此外，如图2所示，该两个网络设备之中，可以有一个网络设备，如网络设备210，负责与该终端设备交互无线资源控制消息，并负责和核心网控制平面实体交互，那么，该网络设备210可以称之为主节点(master node，MN)，例如，主节点可以是MeNB或者MgNB，不限定于此；则另一个网络设备，如网络设备220，可以称之为辅节点(secondary node，SN)，例如，辅节点可以是辅基站(secondary evloved NodeB，SeNB)或者(secondary next generation NodeB，SgNB)，不限定于此。其中，主节点中的多个服务小区可以组成主小区组(master cell group，MCG)，包括一个主小区(primary cell，PCell)和可选的一个或多个辅小区(secondary cell，SCell)。辅节点中的多个服务小区可以组成辅小区组(secondary cell group，SCG)，包括一个主辅小区(primary secondary cell，PSCell)和可选的一个或多个SCell。服务小区是指网络配置给终端设备进行上下行传输的小区。

当然，网络设备220也可以为主基站或主节点，网络设备210也可以为辅基站或辅节点，本申请对此不做限定。另外，图中仅为便于理解，示出了两个网络设备与终端设备之间无线连接的情形，但这不应对本申请所适用的场景构成任何限定。终端设备还可以与更 多的网络设备建立无线链路。

本申请实施例中的网络设备终端设备通过无线方式接入到该移动通信系统中的接入设备，可以是基站NodeB、演进型基站(evloved NodeB,eNB)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、传输点、未来移动通信系统中的基站或无线保真(wireless fidelity，Wi-Fi)系统中的接入节点，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)，或，集中式单元(centralized unit，CU)，或，集中式单元控制面(centralized unit control plane，CU-CP)和集中式单元用户面(centralized unit user plane，CU-UP)等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。在一些部署中，gNB可以包括CU和DU。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。一个CU可以连接一个DU，或者也可以多个DU共用一个CU，可以节省成本，以及易于网络扩展。CU实现gNB的部分功能；DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，以实现无线资源控制(radio resource control，RRC)层，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，以实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。
应理解，CU和DU的切分可以按照上述协议栈进行切分，本申请实施例中并不完全限定上述协议栈切分方式，还可以有其它的切分方式，具体可以参考TR38.801v14.0.0。例如，可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如，按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。

gNB还可以包括有源天线单元(active antenna unit，AAU)。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、CU-CP节点、CU-UP节点、AAU节点中一项或多项的设备。此外，CU可以作为接入网中的网络设备，也可以作为核心网(core network，CN)中的网络设备，本申请对此不做限定。

网络设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请的实施例对无线接入网设备和终端设备的应用场景不做限定。
网络设备和终端设备之间以及终端设备和终端设备之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过免授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和免授权频谱进行通信。网络设备和终端设备之间以及终端设备和终端设备之间可以通过6千兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过6G以上的频谱进行通信，还可以同时使用6G以下的频谱和6G以上的频谱进行通信。本申请的实施例对无线接入网设备和终端设备之间所使用的频谱资源不做限定。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请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 disc，CD)、数字通用盘(digital versatile disc，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。
为了便于理解，这里对本申请实施例涉及到的一些术语或概念作简单介绍。
寻呼(paging)消息的内容是网络设备通过物理下行共享信道(physical downlink shared channel，PDSCH)资源位置发给终端设备的。其中，PDSCH资源是通过寻呼无线网络临时标识(paging radio network temporary identity，P-RNTI)加扰物理下行控制信道(physical downlink control channel，PDCCH)指示的。终端设备要获得寻呼消息，首先要周期性地醒来监视P-RNTI加扰的PDCCH信道，然后解析下行控制信息(downlink control information，DCI)，进一步得到PDSCH信道的时频位置，最后在对应的PDSCH信道的位置解析寻呼消息的内容。
其中，寻呼消息所占的频域资源是由P-RNTI加扰的PDCCH指定的。在时域上，终端设备会在寻呼周期内的某个特定帧(paging frame，PF)的寻呼时机(paging occasion，PO)去尝试接收寻呼消息。PF是一个无线帧，该无线帧包括一个或多个PO。
额外参考信号(additional reference signal，additional RS)是区别于Release-15版本现有的参考信号之外，基站提供的参考信号，用于辅助终端设备进行以下行为中的一项或多项：精确同步，信道/波束追踪，CSI/RRM测量等。额外参考信号可以用于非连续接收(discontinuous reception，DRX)，带宽部分(bandwidth part，BWP)切换，快速SCell激活，减少PDCCH检测，和/或RRM测量等。PO是PDCCH监测时机(monitoring occasions)的集合，可能包含多个时隙(或者子帧，或者正交频分复用(orthogonal frequency division multiplexing，OFDM)符号)，在该PO上可能会有使用P-RNTI加扰，并指示Paging消息的PDCCH。当使用了DRX，终端设备在每个DRX周期(cycle)上只需要检测1个PO，也就是说，对于每个终端设备，在每个Paging周期内只有1个PO可用于发送Paging。其中，对于idle态(空闲态)/inactive态(去激活态)UE来说，DRX cycle与Paging周期是同一概念。
寻呼参数包括寻呼帧号、寻呼周期、寻呼密度、寻呼帧的个数、寻呼帧中寻呼时机的个数等其他可能的参数。比如，寻呼参数可以包括以下中的一项或多项：N,Ns,firstPDCCH-MonitoringOccasionOfPO,PF_offset，以及缺省DRX Cycle的长度(the length of default DRX Cycle)等。N表示一个周期内的PF数，Ns表示PF内的PO数。
其中，对于firstPDCCHMonitoringOccasionOfPO，该信息元素(information element，IE)用来确定PO的起始位置。defaultPagingCycle是默认Paging周期，可表示为“T”。比如，T表示UE的DRX周期。
应理解，这里只是简单介绍了与寻呼相关的内容，对于未涉及到的解释或概念具体可以参考现有协议TS 38.213，TS38.304，TS38.331等中的描述，为了简洁，这里不作赘述。
额外资源(additional resource)：根据TR 38.340，RRM测量采用额外资源(additional resource)有益于终端设备省电。额外资源是指：在现有的同步信号块(synchronization signal block，SSB)测量和信道状态信息参考信号(channel-state information reference signal，CSI-RS)测量之外，引入额外的参考信号用于RRM测量的资源。可选地，额外的参考信号可以是CSI-RS，或者辅同步信号(secondary synchronization signal，SSS)，或者SSB，或者解调参考信号(demodulation reference signal，DMRS)等。额外资源可以适用于处于空闲(idle)/非激活(inactive)/连接(connected)态的终端设备。
在本申请的各个实施例中，如果没有特殊说明以及逻辑冲突，不同的实施例之间的术语和/或描述具有一致性、且可以相互引用，不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
在本申请实施例中，网络设备间通过交互寻呼参数，以便于在配置测量资源时能考虑邻区的寻呼参数，从而尽量减少参考信号对应的时域位置与寻呼消息对应的时域位置之间的时间差，使得终端设备在一次醒来后既能监听寻呼消息，又能对参考信号进行测量，有助于节省终端设备的功耗。

应理解，第一网络设备和第二网络设备可以互相获取对方对应的寻呼参数，比如，第二网络设备也可以获取第一网络设备下的小区的第二寻呼参数，这里以第一网络设备获取第二网络设备下的小区的第一寻呼参数为例进行说明。
第一寻呼参数可用于直接或间接指示终端设备监听来自于第二网络设备的寻呼消息的第一时域位置。比如，第一时域位置是终端设备的寻呼时机PO。若采用直接指示的方式，第一寻呼参数可以直接指示第一时域位置；若采用间接指示的方式，第一寻呼参数中包括的内容可以用于计算第一时域位置。
示例性地，第一寻呼参数可以包括以下中的一项或多项：N,Ns,firstPDCCH-MonitoringOccasionOfPO，PF_offset，以及缺省DRX周期长度(the length of default DRX Cycle)等其他信息。这里，各个参数的解释可以参考前文描述，为了简洁，这里不作赘述。第一寻呼参数与第二网络设备下的小区关联。

S320，第一网络设备根据第一寻呼参数，发送参考信号，其中，所述参考信号的时域位置的根据所述第一时域位置确定的。这里，第一时域位置与参考信号的时域位置距离比较靠近。
在具体实现时，第一网络设备可以将用于发送参考信号的时域位置，与第一时域位置尽量靠近，以便于终端设备一次醒来既能监听寻呼消息，又能对参考信号进行测量，有助 于节省终端设备的功耗。应理解，本申请实施例对终端设备在一次醒来后，“监听寻呼消息”和“测量参考信号”的先后顺序不作具体限定，可以是“监听寻呼消息”在前“测量参考信号”在后，也可以是“测量参考信号”在前“监听寻呼消息”在后，也可以是同时进行。

举例来说，DU1通过F1口将小区1的第二寻呼参数交互给CU1。CU1通过Xn口或X2口将第二寻呼参数交互给CU2。CU2在得到小区1的第二寻呼参数后，在配置用于邻区(比如，小区1)测量的额外资源时，尽量让额外资源的时域位置接近邻区的寻呼时机。可选地，CU2也可以获取其他多个邻区的寻呼参数，比如，小区3，小区4等等，然后配置相应的测量资源。可选地，CU2也可以将配置的额外资源通过Xn口或X2口交互给CU1。CU1可以将测量配置(包括CU2配置的额外资源)发送给UE1，使得UE1根据该测量配置对小区2进行测量。
本申请还提供了一种实施例，网络设备间可以交互额外参考信号的配置，以便于配置终端设备测量邻区的额外参考信号。其中，额外参考信号的配置用于终端设备进行RRM测量。应理解，本申请各个实施例可以独立使用，也可以组合使用，对此不作限定。本申请实施例中的额外参考信号(additional RS)，指的是为了省电的目的为UE配置的额外的参考信号，也可以称为临时RS(temporary RS)，或其它名称，本申请实施例对此不做限定。
