Description

通信方法、装置和系统
本申请要求在2020年1月23日提交中国国家知识产权局、申请号为202010077005.X的中国专利申请的优先权，发明名称为“通信方法、装置和系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、装置和系统。
背景技术
在5G通信系统中，参考信号(reference signal，RS)可以被用作多种用途。为了降低网络的资源开销，避免引入过多的小区级别参考信号，最终确定的小区级别的参考信号在同步信号块(synchronization signal block，SSB)中发送。其中，SSB会周期性发送，并且在某些时隙(NR中时隙为基本调度单位，其长度与子载波间隔大小有关)中发送。例如，在子载波间隔为15kHz的时候，一个时隙长度为1ms，此时一种可能的配置如图1所示，4个SSB在2ms的时间内发送完毕，但是下个周期的4个SSB要在20ms之后才会发送。
若UE(User Equipment，用户设备)处于去激活态或空闲态态时，会在寻呼时机(paging occasion，PO)接收网络侧发送的寻呼(paging)，UE在接收paging之前需要接收paging下行控制信息(downlink control information，DCI)。而且UE在接收paging DCI之前，为了保证paging DCI的接收性能足够好，需要提前进行AGC调整、时频同步等工作，如前面所说，这些工作需要借助参考信号。
由于SSB周期可能比较大，极端情况下，UE可能需要提前很长时间(例如20ms)醒来，如图2所示。此时，UE的睡眠时间缩短，会导致UE功耗的浪费。

具体实施方式

以下，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：
网络设备：又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端设备接入到无线网络的设备，可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的基站，如发送和接收点(Transmission and Reception Point，TRP)、控制器，在此并不限定。一种可能的方式中，接入网设备可以是CU和DU分离架构的基站(如gNB)，如图4所示，图4为本申请一实施例提供的网络设备的协议栈示意图。RAN设备可以与核心网设备相连(例如可以是LTE的核心网，也可以是5G的核心网等)。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。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如无线资源控制(Radio Resource Control，RRC)、业务数据适配协议栈(Service Data Adaptation Protocol，SDAP)以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(Media Access Control，MAC)层，物理(physical，PHY)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。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。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步切分，例如，将控制面(CP)和用户面(UP)分离，即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
无线通信装置：可以是终端设备、芯片或芯片组。终端设备可以是无线终端设备，无线终端设备可以是指一种具有无线收发功能的设备，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(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等，在此不作限定。可以理解的是，本申请实施例中，终端设备也可以称为用户设备(user equipment，UE)。芯片可以是应用于终端设备的芯片，该芯片用于实现终端设备与网络设备进行通信，例如该芯片具有无线收发功能和/或信息处理功能。芯片组可以是应用于终端设备的芯片组，芯片组包括多个芯片，该芯片组用于实现终端设备与网络设备进行通信，例如该芯片组具有无线收发功能和/或信息处理功能。在一些实施例中，终端设备中具有用于与网络设备进行通信的电路，该电路可以集成在一个或多个集成电路(IC)，一个或多个集成电路(IC)可以封装在一个芯片或多个芯片中。以下以无线通信装置为终端设备为例进行说明，以下的终端设备也可以由芯片或芯片组等无线通信装置替换。
在5G移动通信系统中，终端设备所处的状态包括：连接态(connected)、空闲态(idle)以及去激活态(inactive)。终端设备处于连接态时，与网络设备建立空口连接，并根据空口连接与网络设备通信。终端设备处于空闲态或去激活态时，终端设备与网络设备的空口连接断开，终端设备可以接收网络设备发送的广播信息。终端设备处于去激活态时，终端设备与网络设备的空口连接断开，但是继续保存上下文信息，当终端设备由去激活态进入连接态时，基于保存的上下文信息，能快速地恢复到连接态。
在5G通信系统中，参考信号可以用于用户设备(user equipment，UE)进行自动增益控制(Automatic Gain Control，AGC)调整、时频同步、波束测量及无线资源管理(Radio Resource Management，RRM)测量等。在终端设备处于去激活态或空闲态时，会周期性的接收网络设备发送的寻呼(paging，寻呼，包括控制信息(control information)和寻呼消息(paging message))。具体过程为：当处于去激活态或空闲态的终端设备有下行业务产生的时候，网络设备应当告知该终端设备有下行业务，并让该终端设备转入连接态。目前，网络设备通过发送寻呼消息，来告知终端设备有下行业务的。为了避免终端设备的功耗过大，终端设备会周期性监测寻呼消息，每个周期(paging DRX cycle)会出现一个寻呼时机(paging occasion，PO)，在PO内网络设备可以下发寻呼，终端设备检测是否有寻呼。
终端设备在监测寻呼消息的时候，首先要监测paging下行控制信息(downlink  control information，DCI)。Paging DCI使用paging无线网络临时标识(radio network temporary identifier，RNTI)进行标识，只有被分配了对应的P-RNTI(Paging RNTI)的UE能够检测到paging DCI。终端设备(一般是多个终端设备)在收到paging DCI后，会根据该paging DCI的指示接收携带寻呼消息的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。如果终端设备在寻呼消息中检测到了自己的标识(Identity，ID)，则会发起随机接入流程以转入连接态。简而言之，paging DCI可以通知一组寻呼消息“可能需要转到连接态”，进一步寻呼消息会告诉这一组终端设备，具体是哪些终端设备真的要转到连接态。
终端设备在PO内接收paging DCI之前，为了保证paging DCI的接收性能足够好，需要提前进行AGC调整、时频同步等工作。这些工作需要借助网络设备发送的参考信号。而在5G移动通信系统，在一种实现方式中，参考信号通过SSB来传输，由于SSB周期可能比较大，极端情况下，终端设备可能需要提前很长时间(例如20ms，如图2所示)醒来。此时，终端设备的睡眠时间缩短，会导致终端设备功耗的浪费。
在本申请的实施例中，在终端设备处于非连接态时，在PO之前较近的一个时刻能够醒来，接收第一参考信号(用于AGC调整、时频同步等工作)，皆可以节约在SSB处提前醒来而浪费功耗的问题。为了使终端设备能够在第一参考信号处醒来，终端设备可以在非连接态时接收用于配置第一参考信号的信息(第一信息)，根据第一信息可以知道第一参考信号的发送时刻，可以在第一参考信号处醒来。第一参考信号比SSB更靠近PO，因此可以有效地节约终端设备的功耗。以下，结合本申请的各实施例来具体进行说明。
图5为本申请一实施例提供的通信方法的流程图，如图5所示，本实施例的方法可以包括：
S501、在第一无线通信装置处于非连接态时，网络设备向该第一无线通信装置(例如，第一UE)发送系统信息块，所述系统信息块包括第一信息，该第一信息包括第一参考信号的配置信息。相应地，第一无线通信装置在处于非连接态时，接收该系统信息块。
本实施例中，网络设备确定第一参考信号的配置信息，然后网络设备向第一无线通信装置发送第一信息，该第一信息中包括上述第一参考信号的配置信息。配置信息用于使得第一无线通信装置可以接收第一参考信号，配置信息可以包括第一参考信号的时间位置、发送周期、频率位置、频率密度、序列生成参数和QCL(Quasi-co-located，准共址)信息中的一项或几项。示例性的，该序列生成参数可以是扰码ID(scrambling ID)，该序列生成参数用于产生伪随机序列，进而通过伪随机序列生成参考序列，该参考序列。
在一些实施例中，当信道条件不好时，一个第一参考信号可能无法针对一个PO完成AGC调整、时频同步等工作，网络设备可以向第一无线通信装置发送多个第一参考信号。网络设备发送多个第一参考信号时，第一信息可以包括多个配置信息，每个配置信息可以包括一个第一参考信号的时间位置、发送周期、频率 位置、频率密度、序列生成参数和QCL(Quasi-co-located，准共址)信息中的一项或几项。当网络设备发送多个第一参考信号(多个第一参考信号都可以单独进行AGC调整、时频同步，且多个第一参考信号均有效)时，第一无线通信装置还可以判断哪个或哪些第一参考信号离PO更近，并选择接收离PO最近的一个或多个第一参考信号，以更有效地节约第一无线通信装置的功耗。
其中，第一无线通信装置处于非连接态，包括：该第一无线通信装置处于去激活态或空闲态。例如，该第一无线通信装置与该网络设备连接过，该第一无线通信装置由连接态进入去激活态或空闲态；或者，该第一无线通信装置还未与该网络设备连接过，该第一无线通信装置刚刚进入该网络设备所在的小区，该第一无线通信装置处于去激活态或空闲态。
S502、在该第一无线通信装置处于非连接态时，该网络设备根据第一参考信号的配置信息向在该第一无线通信装置发送第一参考信号。相应地，在该第一无线通信装置在处于非连接态时，根据第一参考信号的配置信息从网络设备接收第一参考信号。
本实施例中，当第一无线通信装置处于非连接态时，网络设备根据S501中的第一参考信号的配置信息，向第一无线通信装置发送第一参考信号。相应地，第一无线通信装置在处于非连接态时，根据S501中从网络设备接收的第一参考信号的配置信息，从网络设备接收第一参考信号。SSB是网络设备周期性发送的，第一无线通信装置可以判断SSB的发送时间，同时，第一无线通信装置可以根据第一参考信号的配置信息判断第一参考信号的发送时间，第一参考信号相比于SSB更靠近PO，即第一参考信号离PO更近，则第一无线通信装置在第一参考信号处醒来，根据第一信息接收第一参考信号(用于更好的接收寻呼)，可以避免第一无线通信装置在SSB处过早的醒来，从而降低第一无线通信装置的功耗。
在一些实施例中，如果第一无线通信装置判断SSB更靠近PO，则第一无线通信装置在SSB处醒来，从而降低第一无线通信装置的功耗，并及时进行AGC调整、时频同步等工作。
在一种可能的实现方式中，网络设备和第一无线通信装置位于同一小区，该小区内还存在第二无线通信装置，在第二无线通信装置处于连接态时，网络设备还发送第三信息，第三信息包括第二参考信号的配置信息，第二参考信号为该第二无线通信装置处于连接态时可使用的参考信号。在一个实施例中，网络设备可以将第二参考信号作为第一参考信号的子集，将第二参考信号的配置信息作为第一参考信号的配置信息的至少一部分广播出去，用于第一无线通信装置进行AGC调整、时频同步等工作。由于网络设备需要为处于连接态的第二无线通信装置发送第三信息，因此，无需引入小区级别的配置信息。通过上述配置方法，相同的参考信号既可以给处于非连接态的第一无线通信装置使用，也可以给处于连接态的第二无线通信装置使用，可以节省参考信号的资源。
在一些实施例中，第一无线通信装置可以包括处理器和存储器，第一无线通信装置在接收第一信息后，第一无线通信装置的处理器解析该第一信息，以得到 第一参考信号的接收参数，接收参数用于第一无线通信装置在合适的时间和频率接收第一参考信号，并对第一参考信号进行处理(例如互相关等操作)，得到第一无线通信装置中接收机的时间、频率偏移等信息。为了接收第一参考信号，可以根据接收参数，对第一无线通信装置的芯片或接收机等部件进行调整。接收参数可以存储在存储器中，如果第一参考信号的状态有效，则第一无线通信装置再从存储器中调取接收参数，根据接收参数接收网络设备的第一参考信号。
第一信息指示所指示第一参考信号的配置信息可以为第一无线通信装置处于去激活态或者空闲态的配置信息。相应地，在第一无线通信装置处于去激活态或者空闲态时，网络设备向第一无线通信装置发送第一参考信号，第一无线通信装置根据该配置信息，从网络设备接收第一参考信号。因此，第一无线通信装置无需在处于去激活态时提早从休眠状态醒来以接收第一参考信号，降低了第一无线通信装置的功耗。
在一些实施例中，如果网络设备发现对于一个第一无线通信装置来说，第一参考信号位于SSB与PO之间，网络设备可以广播第一信息；若网络设备发现对于任意一个第一无线通信装置来说，第一参考信号均不位于SSB与PO之间，网络设备可以不广播第一信息，以节约信令开销。
在一个实施例中，每个第一参考信号对应一个配置信息，每个配置信息对应一个有效状态，例如，第一参考信号1对应配置信息1(配置信息1中包括第一参考信号1的时间位置1、发送周期1、频率位置1、频率密度1、序列生成参数1、QCL信息1等)，配置信息1对应有效状态1；第一参考信号2对应配置信息2(配置信息2中包括第一参考信号2的时间位置2、发送周期2、频率位置2、频率密度2、序列生成参数2、QCL信息2等)，配置信息2对应有效状态2；以此类推。
在一些实施例中，第一参考信号用于时间同步、频率同步、增益调整、信道状态测量、链路质量监测或无线资源管理中的一种或几种，用于第一无线通信装置(例如UE)更好的在PO内接收寻呼。其中，时间同步用于第一无线通信装置调整本地时钟，以便在时间上与接收到的下行信号的帧边界、子帧边界、时隙边界、符号边界对齐。频率同步是指调整第一无线通信装置的振荡器，以便在频率上与接收到的下行信号的载波边界、子载波边界对齐。增益调整用于第一无线通信装置调整第一无线通信装置的接收功率放大器，以便使接收到的信号的幅度缩放到合适的范围，既不会信号幅度过小导致精度不足，又不会信号幅度过大导致信号失真。信道状态测量用于第一无线通信装置和/或网络设备对从网络设备到第一无线通信装置间的下行信道的信道状态进行测量。链路质量监测用于第一无线通信装置和/或网络设备对从网络设备到第一无线通信装置间的下行信道的质量进行监测，监测指标包括参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)等。无线资源管理是指第一无线通信装置和/或网络设备对移动通信系统的空中接口资源的规划和调度，负责管理所有的无线资源，如站点、扇区、载频等，包括建立、监视、修改和删除。当第一无线通信装置处于非连接态时，第一无线通信装置可 以根据接收到的寻呼转入连接态。其中，上述各实施例中提及的第一参考信号可以为一种或几种，例如，第一参考信号可以为信道状态信息第一参考信号(channel state information reference signal，CSI-RS)、跟踪第一参考信号(tracking reference signal，TRS)、主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)中的任意一种或几种，也可以是其他第一参考信号，不做限定。
第一无线通信装置在空闲态或去激活态时，仍然可以接收网络设备发送的广播信息，广播消息包括该第一信息，可以保证第一无线通信装置在非连接态接收到第一消息。广播信息包括主信息块(MIB，master information block)和一个或多个系统信息块(SIBs，system information blocks)。系统信息块SIB具有多种类型，如系统信息块1(SIB1，system information block 1)、系统信息块2(SIB2，system information block 2)……系统信息块9(SIB9，system information block 9)等。在一些实施例中，SIB1是用于接入网络必须的信息，SIB2-SIB 5是用于小区重选、测量的信息，SIB6-SIB8是用于地震海啸预警的信息，SIB9是用于GPS timing(卫星对时)的信息。SIB1的空间有限，其它SIB消息(例如SIB2-SIB9)相比于SIB1的空间较大。SIB1是周期性发送的，其它SIB消息由SIB1指示是否发送，由SIB1指示发送的位置。
在一些实施例中，该第一信息包括在SIB1以外的其它类型的SIB(即SIB2～SIBy，y≥3)中，SIB2～SIBy的可用/空余空间比SIB1的可用/空余空间大，可以容纳下第一参考信号的配置信息，且第一信息的变化相对不频繁，将第一信息放在SIB2～SIBy中，可以避免第一信息过于频繁的发送，从而避免增大信令开销。例如，该第一信息包括在SIB2-SIB9中，或者该第一信息包括在专门新引入的SIB(例如SIB10或SIB11等)。该第一信息可以包含在一个或多个SIB，以方便地将第一信息放入SIB中。
在一些实施例中，网络设备还向第一无线通信装置发送第二信息，第二信息用于指示上述第一参考信号的有效状态(即第一参考信号的状态)。相应地，第一无线通信装置从网络设备接收该第二信息，第一无线通信装置接收第二信息的频率大于接收第一信息的频率。
若第二信息指示第一参考信号为有效(即第一参考信号的状态满足条件)，则第一无线通信装置从网络设备接收第一参考信号。在具体的实施例中，若所述第二信息指示第一参考信号为有效(即第一参考信号对应的资源可用，available)，第一无线通信装置根据第一信息，在第一参考信号处唤醒，并接收第一参考信号，可以有效地节约终端设备的功耗。
若第二信息指示第一参考信号为无效(即第一参考信号的状态不满足条件)，则不接收所述第一参考信号。在具体的实施例中，如图5中的步骤S5011，若第二信息指示第一参考信号为无效(即第一参考信号对应的资源不可用，not available)，第一无线通信装置在SSB信号处唤醒，接收SSB信号，不接收所述第一参考信号，避免第一参考信号为无效时未进行AGC调整、时频同步等工作。
因此，网络设备可以向第一无线通信装置指示第一参考信号的有效状态，从而为网络设备的资源控制提供更多灵活性。例如，第一参考信号的有效状态的变化可以与上述第二无线通信装置相关，例如，如果第二无线通信装置处于连接态，则第一参考信号可以为有效；如果第二无线通信装置处于非连接态，则第一参考信号可以为无效。
在一个实施例中，该第一信息包括在SIB1以外的其它类型的SIB(即SIB2～SIBy)中，则第一无线通信装置每次都需要读取一下对应的其它类型的SIB(即SIB2～SIBy，以获得第一参考信号的配置信息)。一般而言，第一参考信号的配置信息的变化不频繁，而第一参考信号的有效状态变化相对比较频繁，通过第二信息指示第一参考信号的有效状态，无需为了更新“第一参考信号的有效状态”而频繁发送对应的其它SIB，可以减小信令开销。
此外，在一些实施例中，第一参考信号的状态还可以包括“可能有效(第一参考信号对应的资源可能可用，may be available)”或“可能无效(即第一参考信号对应的资源可能不可用，may be not available)”。如果第二无线通信装置可能从非连接态进入连接态，则第一参考信号可以为“可能有效”；如果第二无线通信装置可能从连接态进入非连接态，则第一参考信号可以为“可能无效”。
第二信息可以通过一个或几个比特，表示一个第一参考信号的状态。示例性的，第二信息通过每个比特对应一个第一参考信号，则M个第一参考信号需要M个比特来对应。当一个比特为‘0’时，表示对应的第一参考信号“无效”或“可能无效”。当表示对应的第一参考信号“无效”，第一无线通信装置不接收第一参考信号，接收SSB；当表示对应的第一参考信号“可能无效”，第一无线通信装置可以做一定的盲检测，以判断第一无线通信装置是否需要接收第一参考信号(例如，盲检测可以包括功率检测，如果第一无线通信装置的功率较大，则第一无线通信装置接收第一参考信号)。例如，当该一个比特为‘1’时，表示对应的第一参考信号“有效”或“可能有效”。当表示对应的第一参考信号“有效”，第一无线通信装置接收第一参考信号，不接收SSB；当表示对应的第一参考信号“可能有效”，第一无线通信装置可以做一定的盲检测，以判断是否需要接收第一参考信号(例如，盲检测可以包括功率检测，如果第一无线通信装置的功率较大，则接收第一参考信号)。此外，该一个比特的指示方法也可以反过来，即‘0’和‘1’表示与前面举例相反的意思，具体不再赘述。并且，第二信息通过两个比特对应一个第一参考信号，例如，‘00’、‘01’、‘10’和‘11’分别指示第一参考信号“无效”、“可能无效”、“可能有效”和“有效”，第一无线通信装置的处理方法可以参照每个比特对应一个第一参考信号时的处理，在此不再赘述。
以下具体介绍三种第二信息的可能的实现方式：
网络设备发送系统信息块1(system information block 1，简称SIB1)，SIB1包括第二信息，第二信息的信令开销比较小，可以放在SIB1中，SIB1周期发送，从而及时向第一无线通信装置指示第一参考信号的状态。相应的，第一无线通信装置从网络设备接收SIB1，以更新第一参考信号的状态。例如，当网络设备广播 M个第一参考信号的配置信息时，网络设备通过一个bitmap(位图)指示M个第一参考信号的状态，M为大于或等于1的整数。由于该bitmap的信令开销不大，可以放在SIB1中。同时，第一无线通信装置读取SIB1相比于读取SIB2～SIBy更频繁，因此可以更快地获取第一参考信号的状态。对于有能力且有功耗需求的第一无线通信装置来说，可以先从其它SIB(即SIB2～SIBy)中读取M个第一参考信号资源的配置信息。之后工作过程中，根据SIB1中的bitmap确定第一参考信号的有效状态。Bitmap可以通过一个或几个比特，表示一个第一参考信号的状态，具体方法如上所述，在此不再赘述。
由于第一无线通信装置在非连接态正常工作时也需要周期性读取SIB1，因此bitmap放在SIB1中不会增加第一无线通信装置额外的功耗。第一无线通信装置无需每次都读一次完整的配置信息(完整的配置信息包括参考信号的时间位置、发送周期、频率位置、频率密度、序列生成参数、QCL信息等等，因此信令开销比较大)，只需要额外引入一个bitmap(较少的比特，例如，当每个比特对应一个第一参考信号，只需要M个比特)就能指示M个第一参考信号的有效状态。因此会更有效地降低第一无线通信装置的功耗，并节约网络信令开销。此外，第二信息包括在SIB1中，因此，即使第一无线通信装置处于非连接态时，网络设备也可以向第一无线通信装置指示第一无线通信装置在非连接态时上述第一参考信号的有效状态，以保证在资源紧张的情况下可以通过有限的资源令第一无线通信装置获知该信息，防止第一无线通信装置进行错误的测量/同步/AGC调整等。
图6示出一个实施例中各设备所对应的信号，图6中的(a)表示网络设备发送的信号，图6中的(b)表示第一无线通信装置UE1a接收的信号，图6中的(c)表示第一无线通信装置UE1b接收的信号。在图6中，SIBY表示SIB2～SIBy，SIB1-1表示当前的SIB1，SIB1-2表示下一个SIB1，SSB1-1表示第一个SSB周期的SSB信号，SSB1-2表示第二个SSB周期的SSB信号，TRS1-1表示第一个SSB周期内的第一无线通信装置UE1a的第一参考信号，PO1-1表示第一个SSB周期内的第一无线通信装置UE1a的寻呼时机，TRS2-1表示第一个SSB周期内的第一无线通信装置UE1b的第一参考信号，PO2-1表示第一个SSB周期内的第一无线通信装置UE1b的寻呼时机，TRS1-2表示第二个SSB周期内的第一无线通信装置UE1a的第一参考信号，PO1-2表示第二个SSB周期内的第一无线通信装置UE1a的寻呼时机，TRS2-2表示第二个SSB周期内的第一无线通信装置UE1b的第一参考信号，PO2-2表示第二个SSB周期内的第一无线通信装置UE1b的寻呼时机，第一paging周期表示第一无线通信装置UE1a的一个paging周期，第二paging周期表示第一无线通信装置UE1b的一个paging周期。
在一些实施例中，SIB1指示的“有效状态”，可以是从当前SIB1的位置到下一个SIB1之间的所有第一参考信号的有效状态。示例性的，如图6所示，当前的SIB1-1到下一个SIB1-2之间有4个第一参考信号：第一参考信号TRS1-1、第一参考信号TRS2-1、第一参考信号TRS1-2和第一参考信号TRS2-2。则当前的SIB1-1指示第一参考信号TRS1-1、第一参考信号TRS2-1、第一参考信号TRS1-2和第一 参考信号TRS2-2的有效状态。在其它实施例中，SIB1指示的“有效状态”，还可以是从当前SIB1的位置到之后第K(K为大于等于2的整数)个SIB1之间的所有第一参考信号的有效状态，即SIB1可以指示多个SIB1周期内第一参考信号的有效状态。示例性的，K的取值可以是标准中预定义的，也可以是网络设备通过广播信令配置的，也可以是计算得到的。例如，SIB1指示一个PO与其下个周期的PO之间的所有第一参考信号的有效状态，在这两个PO之间发送了L次SIB1，则可以认为K＝L。
寻呼时机PO1-1可以根据第一参考信号TRS1-1进行AGC调整、时频同步等工作，寻呼时机PO1-2可以根据第一参考信号TRS1-2(和第一参考信号TRS1-1)进行AGC调整、时频同步等工作。寻呼时机PO2-1可以根据第一参考信号TRS2-1进行AGC调整、时频同步等工作，寻呼时机PO2-2可以根据第一参考信号TRS2-2(和第一参考信号TRS2-1)进行AGC调整、时频同步等工作。
在可能的实现方式二中：
网络设备发送寻呼消息(paging message)，寻呼消息包括所述第二信息，第二信息的信令开销比较小，可以放在paging message中，paging message周期发送，可以及时向第一无线通信装置指示第一参考信号的状态。相应的，第一无线通信装置从网络设备接收paging message，以更新第一参考信号的状态。例如，当网络设备通过paging message广播M个第一参考信号的配置信息，网络设备通过一个bitmap(位图)指示M个第一参考信号的状态，M为大于或等于1的整数。由于该bitmap的信令开销不大，可以放在paging message中。同时，第一无线通信装置读取paging message相比于读取SIB2～SIBy更频繁，因此第一无线通信装置可以更快地获取第一参考信号的状态。Bitmap可以通过一个或几个比特，表示一个第一参考信号的状态，具体方法如上所述(第二信息可以通过一个或几个比特，表示一个第一参考信号的状态)，在此不再赘述。对于有能力且有功耗需求的第一无线通信装置来说，可以先从其它SIB(即SIB2～SIBy)中读取M个第一参考信号资源的配置信息。之后工作过程中，第一无线通信装置可以在收到paging DCI之后读取bitmap。根据bitmap确定第一参考信号的有效状态。
由于第一无线通信装置在非连接态正常工作时也需要周期性读取paging message，因此bitmap放在paging message中不会增加第一无线通信装置额外的功耗。第一无线通信装置无需每次都读一次完整的配置信息(完整的配置信息包括参考信号的时间位置、发送周期、频率位置、频率密度、序列生成参数、QCL信息等等，因此信令开销比较大)，只需要额外引入一个bitmap(较少的比特，例如，当每个比特对应一个第一参考信号，只需要M个比特)就能指示M个第一参考信号的有效状态。因此会更有效地降低第一无线通信装置的功耗，并节约网络信令开销。此外，第二信息包括在paging message中，因此，即使第一无线通信装置处于非连接态时，网络设备也可以向第一无线通信装置指示第一无线通信装置在非连接态时上述第一参考信号的有效状态，以保证在资源紧张的情况下可以通过有限的资源令第一无线通信装置获知该信息，防止第一无线通信装置进行 错误的测量/同步/AGC调整。此外，paging message的更新比SIB1的更新频繁(SIB1可能以天为单位进行更改)，因此，将bitmap(或第二信息)放在paging message中，可以更及时地更新第一参考信号的有效状态，避免为了读取该bitmap而更频繁的读取SIB1，从而可以更进一步的节约第一无线通信装置的功耗。
在一些实施例中，paging message指示M个第一参考信号的“有效状态”，可以是当前PO到下一个PO之间的所有第一参考信号的有效状态。示例性的，如图6所示，寻呼时机PO1-1和寻呼时机PO1-2之间具有两个第一参考信号(第一参考信号TRS2-1和第一参考信号TRS1-2)，寻呼时机PO1-1的paging message指示第一参考信号TRS1-1和第一参考信号TRS1-2的有效状态。寻呼时机PO2-1和寻呼时机PO2-2之间具有两个第一参考信号(第一参考信号TRS1-2和第一参考信号TRS2-2)，寻呼时机PO2-1的paging message指示第一参考信号TRS1-2和第一参考信号TRS2-2的有效状态。在其它实施例中，paging message指示的“有效状态”，还可以是从当前PO的位置到之后第K(K为大于等于2的整数)个PO之间(即K个paging周期)的所有第一参考信号的有效状态，即paging message可以指示多个PO周期内第一参考信号的有效状态。
寻呼时机PO1-1可以根据第一参考信号TRS1-1进行AGC调整、时频同步等工作，寻呼时机PO1-2可以根据第一参考信号TRS1-2(和第一参考信号TRS1-1)进行AGC调整、时频同步等工作。寻呼时机PO2-1可以根据第一参考信号TRS2-1进行AGC调整、时频同步等工作，寻呼时机PO2-2可以根据第一参考信号TRS2-2(和第一参考信号TRS2-1)进行AGC调整、时频同步等工作。
在可能的实现方式三中：
网络设备发送寻呼消息(paging message)，寻呼消息包括所述第二信息，第二信息的信令开销比较小，可以放在paging message中，paging message周期发送，可以及时向第一无线通信装置指示第一参考信号的状态。相应的，第一无线通信装置从网络设备接收paging message，以更新第一参考信号的状态。例如，当网络设备通过paging message广播M个第一参考信号的配置信息(M为大于或等于1的整数)，每个第一参考信号可能与一个或多个PO有关联关系，每个PO可能与一个或多个第一参考信号，在寻呼时机(paging occasion，PO)内的寻呼消息包含的所述第二信息指示N个所述第一参考信号的状态(1≤N≤M)，可以使用更小的信令开销，就可以指示与当前PO关联的第一参考信号的有效状态。
在一些实施例中，paging message指示“有效状态”的时候，指示的是从当前PO的位置到下一个PO之间的N个第一参考信号的状态，更确切的说，是从当前PO的位置到下一个PO之间的N个第一参考信号的所有occasion的状态。在其它实施例中，paging message指示的“有效状态”，还可以是从当前PO的位置到之后第K(K为大于等于2的整数)个PO之间(即K个paging周期)的所有第一参考信号的有效状态，即paging message可以指示多个PO周期内第一参考信号的有效状态。
参考图6所示，针对第一无线通信装置UE1a，寻呼时机PO1-1和寻呼时机PO1-2之间具有两个第一参考信号(第一参考信号TRS2-1和第一参考信号TRS1-2)，但寻呼时机PO1-2只与第一参考信号TRS1-2有关联关系，寻呼时机PO1-2与第一参考信号TRS2-1无关联关系(寻呼时机PO1-2根据第一参考信号TRS1-2进行AGC调整、时频同步等工作)，则寻呼时机PO1-1内的paging message指示第一参考信号TRS1-2的有效状态，寻呼时机PO1-1内的paging message无需指示第一参考信号TRS2-1的有效状态，从而可以节约信令开销。同理，针对第一无线通信装置UE1b，寻呼时机PO2-1和寻呼时机PO2-2之间具有两个第一参考信号(第一参考信号TRS1-2和第一参考信号TRS2-2)，但寻呼时机PO2-2只与第一参考信号TRS2-2有关联关系，寻呼时机PO2-2与第一参考信号TRS1-2无关联关系(寻呼时机PO2-2根据第一参考信号TRS2-2进行AGC调整、时频同步等工作)，则寻呼时机PO2-1内的paging message指示第一参考信号TRS2-2的有效状态，寻呼时机PO2-1内的paging message无需指示第一参考信号TRS2-1的有效状态，从而可以节约信令开销。
在其它实施例中，寻呼时机PO1-1可以与多个第一参考信号TRS1-1有关联关系；或者，寻呼时机PO1-2可以与多个第一参考信号TRS1-2有关联关系；或者，寻呼时机PO2-1可以与多个第一参考信号TRS2-1有关联关系；或者，寻呼时机PO2-2可以与多个第一参考信号TRS2-2有关联关系；或者，第一参考信号TRS1-1和第一参考信号TRS2-1都与寻呼时机PO2-1有关联关系；或者，第一参考信号TRS2-1和第一参考信号TRS1-2都与寻呼时机PO1-2有关联关系；等等，在此不一一赘述。
paging message可以通过一个或几个比特，表示一个第一参考信号的状态，具体方法如上所述(第二信息可以通过一个或几个比特，表示一个第一参考信号的状态)，在此不再赘述。当paging message可以通过一个比特表示一个第一参考信号的状态时，paging message可以通过N个比特指示当前PO关联的M个第一参考信号的有效状态。
在一些实施例中，所述第一信息还包括第一参考信号与PO的关联信息，所述N个所述第一参考信号为与所述PO有关联关系的N个第一参考信号，即该关联关系通过显式配置确定。具体的，网络设备可以判断哪些第一参考信号与第一无线通信装置的PO相关联，网络设备通过第一信息将第一参考信号与PO的关联关系告知第一无线通信装置，并只需在paging message中指示与当前PO关联的N个第一参考信号的有效状态即可。示例性的，在图6中，寻呼时机PO1-2相关联的为第一参考信号TRS1-2，则在寻呼时机PO1-1，第一无线通信装置UE1a在SIBY处，接收到的第一信息指示寻呼时机PO1-2与第一参考信号TRS1-2相关联；第一无线通信装置UE1a在寻呼时机PO1-1处，接收到的paging message可以仅仅指示第一参考信号TRS1-2的有效状态。
在一些实施例中，该关联关系通过根据第一参考信号的位置与PO的位置隐式确定，例如所述N个所述第一参考信号位于所述寻呼时机前。具体的，示例 性的，在图6中，在寻呼时机PO1-2前示出了三个第一参考信号：第一参考信号TRS1-1、第一参考信号TRS1-2和第一参考信号TRS2-1，第一参考信号TRS2-2位于寻呼时机PO1-2后，则网络设备可以判断第一参考信号TRS1-1、第一参考信号TRS1-2和第一参考信号TRS2-1中的一个或多个与寻呼时机PO1-2相关联，第一参考信号TRS2-2与寻呼时机PO1-2不关联，网络设备在寻呼时机PO1-1的paging message中指示第一参考信号TRS1-1、第一参考信号TRS1-2和第一参考信号TRS2-1中的一个或多个的有效状态，无需指示第一参考信号TRS2-2的有效状态。又如，第一参考信号TRS1-1位于寻呼时机PO1-1、寻呼时机PO2-1和寻呼时机PO1-2之前，则网络设备可以判断寻呼时机PO1-1、寻呼时机PO2-1和寻呼时机PO1-2均与第一参考信号TRS1-1相关联，而第一参考信号TRS2-2位于寻呼时机PO1-1、寻呼时机PO2-1和寻呼时机PO1-2之后，则网络设备可以判断寻呼时机PO1-1、寻呼时机PO2-1和寻呼时机PO1-2均与第一参考信号TRS2-2不关联。
图7为本申请一实施例提供的通信方法的流程图，图7中的各步骤可以采用上述的各实施例中的方法，相同的部分不再赘述。如图7所示，本实施例的方法可以包括：
步骤S701、网络设备在第二无线通信装置处于连接态时，发送第三信息。网络设备与第二无线通信装置(或第二UE)处于同一小区，第三信息包括第二参考信号的配置信息，第二参考信号为该第二无线通信装置处于连接态时可使用的参考信号。网络设备可以将第二参考信号的配置信息作为第一参考信号的配置信息的至少一部分广播出去(例如可以将第二参考信号凑成第一信号)，用于第一无线通信装置进行AGC调整、时频同步等工作，第二参考信号为第一参考信号的子集。相应的，第二无线通信装置处于连接态时，接收该第三信息。通过上述配置方法，相同的参考信号既可以给处于非连接态的第一无线通信装置使用，也可以给处于连接态的第二无线通信装置使用，可以节省参考信号的资源。
步骤S702、在第一无线通信装置处于非连接态时，网络设备向该第一无线通信装置(或第一UE)发送系统信息块，所述系统信息块包括第一信息，该第一信息包括第一参考信号的配置信息。相应地，第一无线通信装置在处于非连接态时，从网络设备接收该系统信息块。该第一无线通信装置解析第一信息，并得到接收参数，接收参数用于接收第一参考信号。第一无线通信装置可以先不读取该第一信息，第一信息可以存储在第一无线通信装置的存储器中，如果第一参考信号有效，则第一无线通信装置再从存储器中调取第一信息。
其中，第一无线通信装置处于非连接态，包括：该第一无线通信装置(或第一UE)处于去激活态或空闲态。例如，该第一无线通信装置与该网络设备连接过，该第一无线通信装置由连接态进入去激活态或空闲态；或者，该第一无线通信装置还未与该网络设备连接过，该第一无线通信装置刚刚进入该网络设备所在的小区，该第一无线通信装置处于去激活态或空闲态。
步骤S703、在第一无线通信装置处于非连接态时，网络设备向第一无线通 信装置发送第二信息，第二信息用于指示上述第一参考信号的有效状态(即状态)。相应地，第一无线通信装置从网络设备接收该第二信息，第一无线通信装置接收第二信息的频率大于接收第一信息的频率。第二信息可以是上述实施例中的任意一种实现方式，在此不再赘述。第二信息可以指示第一参考信号的有效状态，因此无需每次读取第一参考信号的配置信息，可以进一步的节约第一无线通信装置的功耗。
步骤S704、第一无线通信装置根据第二信息所指示的第一参考信号的有效状态，判断第一参考信号是否可用。若第一参考信号有效(第一参考信号的状态满足条件)，第一参考信号可用；若第一参考信号无效(第一参考信号的状态不满足条件)，第一参考信号不可用。
此外，第一参考信号的状态还可以包括“可能有效(第一参考信号对应的资源可能可用，may be available)”或“可能无效(即第一参考信号对应的资源可能不可用，may be not available)”。如果第二无线通信装置可能从非连接态进入连接态，则第一参考信号可以为“可能有效”；如果第二无线通信装置可能从连接态进入非连接态，则第一参考信号可以为“可能无效”。如果第一参考信号的状态为可能有效或可能无效，则第一无线通信装置可以做一定的盲检测，以判断是否需要接收第一参考信号。
步骤S705、若第二信息指示第一参考信号为无效(即第一参考信号的状态不满足条件)，则不接收所述第一参考信号。在具体的实施例中，若第二信息指示第一参考信号为无效(即第一参考信号对应的资源不可用)，第一无线通信装置在SSB信号处唤醒，接收SSB信号，不接收所述第一参考信号，避免第一参考信号为无效时未进行AGC调整、时频同步等工作。
步骤S706、若第二信息指示第一参考信号为有效(即第一参考信号的状态满足条件)，则第一无线通信装置根据接收参数，从网络设备接收第一参考信号。在具体的实施例中，若所述第二信息指示第一参考信号为有效(即第一参考信号对应的资源可用)，第一无线通信装置根据第一信息，在第一参考信号处唤醒，并接收第一参考信号，可以有效地节约终端设备的功耗。当第一无线通信装置处于非连接态时，第一无线通信装置可以根据第一参考信号的配置信息判断第一参考信号的发送时间，第一参考信号相比于SSB更靠近PO，即第一参考信号离PO更近，则第一无线通信装置在第一参考信号处醒来，根据第一信息接收第一参考信号(用于更好的接收寻呼)，可以避免第一无线通信装置在SSB处过早的醒来，从而降低第一无线通信装置的功耗。
步骤S707、第一无线通信装置根据收到的第一参考信号或SSB，进行AGC调整、时频同步，以更好地接收paging DCI。
步骤S708、在第一无线通信装置处于非连接态，在寻呼时机(第一无线通信装置的寻呼时机)内，网络设备向第一无线通信装置发送寻呼。相应地，第一无线通信装置从网络设备接收该寻呼，以判断是否需要转入连接态。
步骤S709、第二无线通信装置根据第三信息，并调整时频偏，以更好地接收 下行信号。
步骤S710、在第二无线通信装置处于连接态时，网络设备向第二无线通信装置发送下行信号。相应地，第二无线通信装置接收网络设备发送的下行信号。
通过上述步骤的方法，可以有效地节约第二无线通信装置的功耗，且不会增加小区级别的配置信息，信令开销不大。
以上各步骤并不限于图7所示的顺序，例如，步骤S709可以在步骤S701和步骤S710之间的任意位置，步骤S708和步骤S710的位置可以互换，步骤S702和步骤S703的位置可以互换，等等。
图8为本申请一实施例提供的通信装置的结构示意图，如图8所示，通信装置可以是第一无线通信装置，也可以是第一无线通信装置的部件(例如，集成电路，芯片等等)，或者可以是其他通信模块，用于实现上述任一实施例中对应于第一无线通信装置的操作，例如，所述第一无线通信装置为终端设备、芯片或芯片组。本实施例的通信装置700包括：接收模块701。在一个实施例中，本实施例的通信装置700还可以包括存储模块702和处理模块703。
接收模块701，用于在无线通信装置处于非连接态时，接收第一信息，所述第一信息包括第一参考信号的配置信息，所述第一参考信号为所述无线通信装置处于非连接态时可使用的参考信号；以及，根据所述第一信息从网络设备接收所述第一参考信号。
本实施例中，当第一无线通信装置处于非连接态时，接收第一参考信号，第一无线通信装置可以根据第一参考信号的配置信息判断第一参考信号的发送时间，第一参考信号相比于SSB更靠近PO，即第一参考信号离PO更近，则第一无线通信装置在第一参考信号处醒来，根据第一信息接收第一参考信号(用于更好的接收寻呼)，可以避免第一无线通信装置在SSB处过早的醒来，从而降低第一无线通信装置的功耗。
在一个实施例中，所述第一参考信号用于时间同步、频率同步、增益调整、信道状态测量、链路质量监测或无线资源管理中的一项或几项。
