Description

参考信号处理方法、装置及系统

技术领域
本申请涉及通信技术领域，尤其涉及一种参考信号处理方法、装置及系统。
背景技术
第五代(5th generation，5G)新空口(new radio，NR)的高频(6GHz以上，如毫米波)通信中，引入了波束赋形(beam forming)技术，有效对抗路径损耗(path loss)。基于此，网络设备和终端设备均能够使用多个不同指向/方向的波束进行通信。为了良好的通信质量，网络设备和终端设备需要进行波束跟踪，来达到波束对准的效果。
目前，在波束跟踪的过程中，终端设备需要测量网络设备发送的用于波束测量(beam measurement)的全部无线信号后才能对波束进行调整。
然而，随着网络设备大规模天线阵列技术的不断演进，网络设备使用的波束的宽度越来越窄。这样，如果波束跟踪的覆盖区域保持不变，那么，网络设备使用的波束的数量变多，需要终端设备测量无线信号的数量也变多，导致终端设备的功耗变高。如果终端设备测量无线信号的数量保持不变，那么，波束跟踪的覆盖区域变小，需要网络设备频繁的重新配置波束，来增大波束跟踪的覆盖区域，否则容易发生波束失败(beam failure)。

首先，下面对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
波束(beam)：波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术、模拟波束成形技术、或者混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选的，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
在使用低频频段或中频频段时，可以全向发送信号或者通过一个较宽的角度来发送信号，而在使用高频频段时，得益于高频通信系统较小的载波波长，可以在发送端和接收端布置很多天线阵子构成的天线阵列，发送端以一定波束赋形权值发送信号，使发送信号形成具有空间指向性的波束，同时在接收端用天线阵列以一定波束赋形权值进行接收，可以提高信号在接收端的接收功率，对抗路径损耗。
准同位/准共址(quasi-co-location，QCL)：同位关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有同位关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口具有同位关系，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。大尺度特性可以包括：延迟扩展，平均延迟，多普勒扩展，多普勒频移，平均增益，接收参数，终端设备接收波束编号，发射/接收信道相关性，接收到达角，接收机天线的空间相关性，主到达角(Angel-of-Arrival，AoA)，平均到达角，AoA的扩展等。具体地，同位关系用于指示至少两组天线端口是否具有同位关系，或同位关系用于指示至少两组天线端口发送的信道状态信息参考信号是否来自相同的传输点，或同位关系用于指示至少两组天线端口发送的信道状态信息参考信号是否来自相同的波束组。
参考信号(reference signal，RS)：根据长期演进(long term evolution，LTE)/NR的协议，在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括：随机接入信道(random access channel，PRACH)、上行控制信道(physical uplink control channel，PUCCH)、上行数据信道(physical uplink shared channel，PUSCH)等，上行信号包括：上行探测参考信号(sounding reference signal，SRS)、上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)、上行数据信道解调参考信号(PUSCH de-modulation reference signal，PUSCH-DMRS)、上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)、上行定位信号(uplink positioning RS)等。下行通信包括下行物理信道和下行信号的传输。其中下行物理信道包括广播信道(physical broadcast channel，PBCH)、下行控制信道(physical downlink control channel，PDCCH)、下行数据信道(physical downlink shared channel，PDSCH)等，下行信号包括主同步信号(primary synchronization signal，PSS)/辅同步信号(secondary synchronization signal，SSS)、下行控制信道解调参考信号(PDCCH de-modulation reference signal，PDCCH-DMRS)、下行数据信道解调参考信号(PDSCH de-modulation reference signal，PDSCH-DMRS)、下行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)、信道状态信息参考信号(channel status information reference signal，CSI-RS)、小区信号(Cell reference signal，CRS)、精同步信号(time/frequency tracking reference signal，TRS)、LTE/NR定位信号(positioning RS)等。其中，PSS、SSS和PBCH共同构成同步信号块(synchronization signal block，SSB)。
本申请提供一种参考信号处理方法。其中，本申请的参考信号处理方法可以应用于通信系统，通信系统可以包括但限于：无线通信系统，例如，窄带物联网系统(narrow band-Internet of things，NB-IoT)、全球移动通信系统(global system for mobile communications，GSM)、增强型数据速率GSM演进系统(enhanced data rate for GSM evolution，EDGE)、宽带码分多址系统(wide band  code division multiple access，WCDMA)、码分多址2000系统(code division multiple access，CDMA2000)、时分同步码分多址系统(time division-synchronization code division multiple access，TD-SCDMA)、LTE系统、第五代(the 5th generation，5G)系统、第六代(the 6th generation，6G)系统、以及未来的系统等。
请参阅图1，图1示出了本申请一实施例提供的一种通信系统的架构示意图。如图1所示，本申请的通信系统1可以包括：网络设备20和终端设备10。
其中，网络设备20与终端设备10可进行通信，网络设备20可以包括一个或多个。网络设备20：可以是基站，或者接入点，或者接入网设备，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。网络设备20可用于将收到的空中帧与网际互联协议(Internet protocol，IP)分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备20还可协调对空中接口的属性管理。例如，网络设备20可以是卫星、无人机、全球移动通讯(global system of mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(NodeB，NB)，还可以是LTE中的演进型基站(evolutional node B，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者可穿戴设备或车载设备、车接其他(vehicular to everything，V2X)、设备对设备通信(Device-to-Device，D2D)、和机器对机器通信(Machine-to-Machine，M2M)通信中承担基站功能的终端或者中继站或接入点，或者5G网络中的基站，例如gNB等，或者未来的6G网络中的基站，或者未来演进的共用陆地移动网(public land mobile network，PLMN)网络中的网络设备，在此并不限定。
其中，终端设备10可以包括一个或多个。终端设备10可以是无线终端，也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、无人机、可穿戴设备、车联网中的终端等设备。无线终端也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device or user equipment)、用户设备(user equipment，UE)、终端单元、终端站、远方站、移动设备、终端、无线通信设备、终端代理或终端装置等，在此不作限定。
接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络或未来的6G网络中的终端设备或者未来演进的公用陆地移动网(public land mobile network，PLMN)网络中的终端设备等。
此外，终端设备10可以采用如Android系统、Linux系统、Windows系统、iOS系统、鸿蒙操作系统(harmony operating system，鸿蒙OS)等移动操作系统，本申请对此不做限定。
网络设备20与终端设备10之间可传输无线信号。通信系统的高频通信中，无线信号的质量可能出现大幅度的衰减，容易引起路径损耗，甚至导致通信系统无法正常工作。为了良好的通信质量，引入了波束赋形技术，波束具有方向性，可有效对抗路径损耗。
如图1所示，网络设备20可配置大规模天线(massive MIMO)阵列，例如，64根、128根、256根、1024根天线或其他数量的天线。从而，通过天线阵列实现通信，可提高无线信号的传输质量。上述提及的波束赋形技术可以通过调节各个天线的相位实现信号的有效叠加，使得无线信 号的增益更大，可对抗路径损耗，为无线信号的传输质量提供保障。
其中，上述提及的波束成形技术可以应用于网络设备20，也可以应用于终端设备10(即终端设备10也可以配置天线阵列)，也可同时应用于网络设备20和终端设备10，本申请对此不做限定。
基于上述描述，在网络设备20作为发送端，终端设备10为接收端时，如图1所示，网络设备20可以使用多个不同指向的波束(Tx beam)向不同方向发射无线信号，实现服务区域的覆盖。对应地，终端设备10可使用多个不同指向的波束(Rx beam)，来接收来自于网络设备20发射的不同方向的无线信号。
此外，网络设备20也可使用一个指向的波束发送无线信号，本申请对网络设备20使用多少个波束发送无线信号不做限定。终端设备10也可使用一个指向的波束接收无线信号，本申请对终端设备10使用多少个波束接收无线信号不做限定。应理解，图1仅为示意性的举例。
并且，上述提及的波束赋形技术可对无线信号的能量产生聚焦，形成一个指向性波束(beam)，使无线信号的能量集中在接收端所在的方向。也就是说，发送端使用的波束的指向偏离接收端较小或者对准接收端，接收端便能够接收到高质量的无线信号。发送端使用的波束的指向偏离接收端，接收端可能无法接收到高质量的无线信号。
在发送端和/或接收端使用不同指向的波束时，存在一对波束(即包括发送端使用的一个波束和接收端使用的一个波束)相比于其他波束的组合来说，该一对波束的指向对准或者偏差较小，具有良好的对齐度。从而，使得接收端能够接收到高质量的无线信号。
其中，该一对波束可称之为波束对，波束对可以包括发送端使用的一个波束(即发射波束)和接收端使用的一个波束(即接收波束)，即发射波束和接收波束指向对准或者偏差较小，波束对的对齐度较好。例如，在终端设备接收到的参考信号的接收信号功率(reference signal received power，RSRP)大于等于预设阈值时，可看作是网络设备发送该参考信号使用的发射波束与终端设备接收该参考信号使用的接收波束形成的波束对的对齐度较好。或者，在发射波束和接收波束满足一定的通信要求时，可看作是波束对的对齐度较好。
基于上述描述，继续结合图1，在网络设备20与终端设备10使用波束对进行无线信号传输时，网络设备20使用波束对中的发射波束发射无线信号，终端设备10使用波束对中的接收波束接收无线信号，使得终端设备10能够接收到高质量的无线信号，有利于提高通信质量。
由于终端设备10具有移动性，终端设备10使用的波束的指向会随着终端设备10的位置、终端设备10的姿态、终端设备10的天线是否被遮挡等情况的变化而发生变化。因此，网络设备20与终端设备10使用的波束对也会随之发生变化。基于此，为了保证网络设备20与终端设备10能够始终使用对齐度较好的波束对进行无线信号的传输，网络设备20和终端设备10需要持续进行波束跟踪。
在终端设备10接入到网络之前，即终端设备10处于非激活态或空闲态，网络设备20和终端设备10可以先通过测量参考信号，得到一组或多组对齐度较好的波束对。从而，使用前述一组或多组波束对能够发起随机接入过程，使得终端设备10能够接入网络。
在终端设备10接入到网络之后，即终端设备10处于无线资源控制(radio resource control，RRC)连接态，网络设备20和终端设备10可使用在随机接入过程中得到的波束对。如果终端设备10的位置、终端设备10的姿态、终端设备10的天线是否被遮挡等情况发生变化，那么在随机接入过程中得到的波束对将无法保障通信质量。故，网络设备20和终端设备10还需要继续通过测量参考信号，得到一组或多组对齐度较好的波束对。从而，使用该波束对能够实现无线信号的传输。
在上述波束跟踪的过程中，无论终端设备10接入到网络之前还是终端设备10接入到网络之后，终端设备10皆需要测量网络设备20发送的用于波束测量的全部无线信号，之后才能对需要测量的参考信号进行更新，来达到波束对准的效果。
然而，随着网络设备20配置的天线阵列越来越大，网络设备20使用的波束的宽度越来越窄。在保持波束跟踪的覆盖区域不变的情况下，网络设备20使用的波束的数量会变多，从而需要终端设备10测量越来越多的参考信号，导致终端设备10的功耗变高。在保持终端设备10测量的参考 信号的数量不变的情况下，波束跟踪的覆盖区域会变小，从而需要网络设备20频繁的重新配置波束，来增大波束跟踪的覆盖区域，否则容易发生波束失败。
考虑到上述问题，本申请提供一种参考信号处理方法，可通过网络设备向终端设备指示：根据协议预定义或者网络设备配置的参考信号对应的波束的空间位置信息，使得终端设备能够精准地选择待测量的参考信号。
下面，本申请以下实施例将以具有图1所示结构的终端设备10和网络设备20为例，结合附图和应用场景，对本申请提供的参考信号处理方法进行详细阐述。
请参阅图2，图2示出了本申请一实施例提供的一种参考信号处理方法的信令交互图。如图2所示，本申请提供的参考信号处理方法可以包括：
S101、网络设备向终端设备发送第一消息，第一消息中包括第一参考信号集合对应的波束的空间位置信息，第一参考信号集合中包括一个或多个参考信号。
网络设备可确定第一参考信号集合对应的波束的空间位置信息，即第一参考信号集合中的参考信号对应的波束的空间位置信息，第一参考信号集合对应的波束的空间位置信息用于更新待测量的参考信号。
其中，一个参考信号通常使用一个波束发送。因此，每个参考信号对应一个波束的空间位置信息。另外，一个参考信号也可使用一个多峰波束发送，且本申请可将多峰波束看作为多个波束。因此，每个参考信号对应一个多峰波束的空间位置信息，即每个参考信号对应多个波束的空间位置信息，这里的多个波束为一个多峰波束。
其中，参考信号对应的波束的空间位置信息用于确定波束对应的参考信号。
其中，第一参考信号集合中可以包括网络设备确定出的一个或多个参考信号。在终端设备接入到网络之前，网络设备根据协议预定义的时频资源信息可确定第一参考信号集合。在终端设备接入到网络之后，网络设备根据网络设备配置的时频资源信息，如RRC信令配置的时频资源信息，可确定第一参考信号集合。
其中，本申请对第一参考信号集合中的参考信号的类型不做限定。例如，第一参考信号集合中的参考信号可以包括：同步/广播信号块SSB、信道状态信息参考信号CSI-RS、上行探测参考信号SRS、解调参考信号(demodulation reference signal，DMRS)、或者跟踪参考信号TRS中的一种或多种类型。在第一参考信号集合中包括多个参考信号时，多个参考信号的类型可以为一种或多种。
从而，网络设备可向终端设备发送携带有第一参考信号集合对应的波束的空间位置信息的第一消息。
其中，本申请对第一消息的发送方式不做限定。在一些实施例中，第一消息可承载在控制信道和/或数据信道对应的信令中。例如，第一消息可承载在如RRC信令、下行控制指示(downlink control indication，DCI)信令、或者媒体接入控制控制元素(medium access control-control element，MAC-CE)信令等中的一个或多个信令中。
S102、终端设备根据历史的第二参考信号集合中的一个或多个参考信号的测量结果、以及第一参考信号集合对应的波束的空间位置信息，得到更新的第二参考信号集合，第二参考信号集合中的一个或多个参考信号包含在第一参考信号集合中。
其中，历史的第二参考信号集合中的一个或多个参考信号的测量结果用于表示历史的第二参考信号集合中被测量的参考信号对应的信道状态和/或信号质量。历史的第二参考信号集合中的一个或多个参考信号的测量结果可为终端设备在得到更新的第二参考信号集合之前，对历史的第二参考信号集合中的参考信号进行测量得到的。历史的第二参考信号集合中的一个或多个参考信号的测量结果可为终端设备上一次或上多次的测量结果，本申请对此不做限定。
其中，历史的第二参考信号集合中的一个或多个参考信号可为历史的第二参考信号集合中的全部参考信号或部分参考信号，本申请对此不做限定。
其中，S102提及的第二参考信号集合可包括历史的第二参考信号集合和更新的第二参考信号集合。故历史的第二参考信号集合中的一个或多个参考信号包含在第一参考信号集合中。
在一些实施例中，历史的第二参考信号集合与第一参考信号集合可为同一个集合。或者，历 史的第二参考信号集合可为第一参考信号集合的子集。
在另一些实施例中，历史的第二参考信号集合与第一参考信号集合之间可存在交集，即存在相同的一个或多个参考信号。换句话说，历史的第二参考信号集合中，除了前述的相同的一个或多个参考信号之外，还包括其他的一个或多个参考信号。且第一参考信号集合中，除了前述的相同的一个或多个参考信号之外，还包括其他的一个或多个参考信号。
另外，历史的第二参考信号集合中的参考信号与第一参考信号集合中的参考信号的类型可相同或不同。
基于上述描述，终端设备根据历史的第二参考信号集合中的一个或多个参考信号的测量结果，可确定历史的第二参考信号集合中的信号质量好的参考信号。由于第二参考信号集合中的一个或多个参考信号包含在第一参考信号集合中。因此，终端设备结合第一参考信号集合对应的波束的空间位置信息，可确定第一参考信号集合中的信号质量好的参考信号。
从而，终端设备可将第一参考信号集合中的信号质量好的参考信号确定为更新的第二参考信号集合，使得终端设备能够确定之后待测量哪些参考信号。
其中，更新的第二参考信号集合是终端设备实际测量的参考信号集合。更新的第二参考信号集合为终端设备用于确定之后待测量的参考信号的时频资源信息。更新的第二参考信号集合中通常可以包括多个参考信号。
其中，S102提及的第二参考信号集合可包括历史的第二参考信号集合和更新的第二参考信号集合。故更新的第二参考信号集合中的一个或多个参考信号包含在第一参考信号集合中。
在一些实施例中，更新的第二参考信号集合与第一参考信号集合可为同一个集合。或者，更新的第二参考信号集合可为第一参考信号集合的子集。
在另一些实施例中，更新的第二参考信号集合与第一参考信号集合之间可存在交集，即存在相同的一个或多个参考信号。换句话说，更新的第二参考信号集合中，除了前述的相同的一个或多个参考信号之外，还包括其他的一个或多个参考信号。且第一参考信号集合中，除了前述的相同的一个或多个参考信号之外，还包括其他的一个或多个参考信号。
另外，更新的第二参考信号集合中的参考信号与第一参考信号集合中的参考信号的类型可相同或不同。
另外，更新的第二参考信号集合与历史的第二参考信号集合可以相同或不同。在终端设备对更新的第二参考信号集合进行测量后，更新的第二参考信号集合可成为终端设备之后待测量的参考信号的历史的第二参考信号集合。
S103、网络设备向终端设备发送第三参考信号集合中的参考信号。
网络设备可终端设备发送第三参考信号集合中的参考信号。
其中，第三参考信号集合可包括在终端设备接入网络之前发送的一个或多个参考信号。或者，第三参考信号集合可包括在终端设备接入网络之后发送的一个或多个参考信号。或者，第三参考信号集合可包括在终端设备接入网络之前发送的一个或多个参考信号以及第三参考信号集合可包括在终端设备接入网络之后发送的一个或多个参考信号。
其中，第三参考信号集合中的参考信号的类型与第一参考信号集合中的参考信号的类型可以相同或不同。
另外，第一参考信号集合和第三参考信号集合的交集不为空，但不一定存在包含关系。
在一些实施例中，第一参考信号集合与第三参考信号集合之间可存在交集，即存在相同的一个或多个参考信号。换句话说，第一参考信号集合中，除了前述的相同的一个或多个参考信号之外，还包括其他的一个或多个参考信号。且第三参考信号集合中，除了前述的相同的一个或多个参考信号之外，还包括其他的一个或多个参考信号。
在另一些实施例中，第一参考信号集合与第三参考信号集合可为同一个集合。或者，第一参考信号集合可为第三参考信号集合的子集。或者，第三参考信号集合可为第一参考信号集合的子集。
应理解，上述S103和S101之间没有时序上的先后顺序，且S103和S101可以同时执行，也可以顺序执行。
综上，终端设备能够精准地选择待测量的参考信号，降低了终端设备的测量量和能耗，也无需网络设备重新配置参考信号，降低了信令交互的时延和开销，降低了波束失败的发生概率，提高了通信系统的性能。
基于上述描述，第三参考信号集合中的参考信号可用于波束测量，也可用于其他功能。在更新的第二参考信号集合中的一个或多个参考信号包含在第三参考信号集合中的情况下，终端设备可确定第三参考信号集合中的参考信号用于波束测量。从而，终端设备可选择执行S104。
其中，更新的第二参考信号集合中的一个或多个参考信号包含在第三参考信号集合中。
在一些实施例中，更新的第二参考信号集合与第三参考信号集合可为同一个集合。或者，更新的第二参考信号集合可为第三参考信号集合的子集。
