相关申请的交叉引用
本申请要求在2019年05月10日提交中国专利局、申请号为201910390894.2、申请名称为“一种通信方法及装置”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
本申请涉及无线通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在无线通信系统中，处于无线电资源控制(radio resource control，RRC)连接态的终端设备常需要进行无线电资源管理(radio resource management，RRM)测量。
具体来说，网络设备可以周期性地广播参考信号，终端设备可以通过网络设备广播的参考信号实现RRM测量，例如，终端设备可以根据对参考信号的接收结果分别测量当前小区和周围相邻小区的服务质量，并根据所得到的当前小区和周围相邻小区的服务质量确定是否进行小区切换。
通常，网络设备会为终端设备分配多个测量位置，每一个测量位置对应于一个参考信号的时域位置。终端设备可以在这些测量位置上接收参考信号，执行RRM测量。通常，终端设备和网络设备在这些测量位置上存在调度限制，例如在这些测量位置上，终端设备和网络设备之间停止了下行和上行数据传输。然而，终端设备往往只会使用多个测量位置中的部分测量位置执行RRM测量，因此便造成了信道资源浪费。
发明内容
本申请的目的在于提供了一种通信方法及装置，可以使网络设备在为终端设备分配的一些测量位置上解除调度限制，从而可以增加对终端设备的调度机会，有利于提高信道资源利用率。
上述目的和其他目的将通过独立权利要求中的特征来达成。进一步的实现方式在从属权利要求、说明书和附图中体现。
第一方面，本申请实施例提供一种通信方法，包括：终端设备根据第一时间段内的多个测量位置确定限制位置，在限制位置中包括了终端设备从多个测量位置中所确定的、用于执行RRM测量的目标测量位置；终端设备进而向网络设备发送指示信息，通过指示信息向网络设备指示在上述多个测量位置中，除限制位置之外的测量位置可以作为可用测量位置，被网络设备用于调度终端设备。
采用上述方法，终端设备提前确定第一时间段内的限制位置，并通过向网络设备发送指示信息，以向网络设备指示在为终端设备分配的多个测量位置中，除限制位置之外的可用测量位置。网络设备在第一时间段内便可以在可用测量位置上解除调度限制，调度终端设备工作，从而可以增加对终端设备的调度机会，有利于提高信道资源利用率。而且，由 于限制位置中包括了终端设备在第一时间段内用于执行RRM测量的目标测量位置，因此网络设备的可用测量位置中并不包括终端设备的目标测量位置，使得即使网络设备在可用测量位置上调度终端设备，也不会(或较小地)干扰到终端设备的RRM测量。
示例性的，限制位置可以为目标测量位置。网络设备可以根据终端设备的指示信息确定终端设备的目标测量位置，并在调度终端设备时，网络设备可以在目标测量位置之前的一个数据符号的时间长度和目标测量位置之后的一个数据符号的时间长度上保持调度限制，即为目标测量位置提供一定的时间冗余，以用于终端设备切换处理能力，例如针对不同子载波间隔的处理能力，或者用于降低其它可能存在的调度过程对RRM测量的干扰。
可以理解，终端设备所确定的限制位置也可以为目标测量位置、目标测量位置之前的一个数据符号的时间长度和目标测量位置之后的一个数据符号的时间长度，在此情况下，终端设备主动为目标测量位置预留了一定的时间冗余，网络设备可以直接在确定的可用测量位置上调度终端设备。
此外，限制位置也可以为目标测量位置所在的测量窗。在网络设备以测量窗的形式为终端设备分配多个测量位置的情况下，终端设备也可以直接以测量窗为单位确定限制位置，即将目标测量位置所在的测量窗作为限制位置。

示例性的，在上述至少一个限制位置为目标测量位置所在的至少一个测量窗的情况下，该指示信息可以包括目标测量位置所在的至少一个测量窗的标识信息，或者，指示信息包括可用测量位置所在的至少一个测量窗的标识信息。

在一种可能的实现方式中，至少一个限制位置为目标测量位置所在的至少一个测量窗，指示信息包括目标测量位置所在的至少一个测量窗的标识信息；在此情况下，网络设备根据指示信息确定为终端设备分配的第一时间段内的多个测量位置中的可用测量位置，包括：网络设备根据至少一个测量窗的标识信息，确定至少一个测量窗的标识信息分别对应的至少一个测量窗；网络设备确定多个测量位置中，除至少一个测量窗中包括的测量位置之外的测量位置为可用测量位置；或者，指示信息包括可用测量位置所在的至少一个测量窗的标识信息；在此情况下，网络设备根据指示信息确定为终端设备分配的第一时间段内的多个测量位置中的可用测量位置，包括：网络设备根据至少一个测量窗的标识信息，确定至少一个测量窗的标识信息分别对应的至少一个测量窗中包括的测量位置为可用测量位置。
在一种可能的实现方式中，指示信息还用于指示第一时间段。
在一种可能的实现方式中，在多个测量位置中存在至少一个限制位置的情况下，指示信息用于指示至少一个第二时间段，该至少一个第二时间段为第一时间段内除至少一个限制位置之外的全部或部分时间段；在此情况下，网络设备可以根据所述指示信息，确定至少一第二时间段中的测量位置为所述可用测量位置。

图1中的网络设备可以为接入网设备，例如基站。其中，接入网设备在不同的系统对应不同的设备，例如在第四代移动通信技术(the 4 th generation，4G)系统中可以对应eNB，在5G系统中对应5G中的接入网设备，例如gNB。尽管在图1中仅示出了终端设备120、 终端设备130和终端设备140，应理解，网络设备可以为多个终端设备提供服务，本申请实施例对通信系统中终端设备的数量不作限定。同理，图1中的终端设备是以手机为例进行说明的，也应理解，本申请实施例中的终端设备不限于此。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备，又可称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。所述终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。例如，终端设备可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的示例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)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。
2)网络设备，是网络中用于将终端设备接入到无线网络的设备。所述网络设备可以为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(radio access network，RAN)节点(或设备)。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备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。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(5th generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)，或者还可以包括传输接收点(transmission reception point，TRP)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或WiFi接入点(access point，AP)等，再或者还可以包括云接入网(cloud radio access network，CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
3)同步信号/广播信道块SSB，SSB包括主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)和物理广播信道(physical broadcast channel，PBCH)。一个SSB在时域上占用连续的4个OFDM符号，在频域上占用连续的240个子载波。
4)下行数据信道，用于承载下行数据信息。例如为物理下行共享信道(physical downlink shared channel，PDSCH)，或者为增强的物理下行共享信道(enhanced physical downlink control channel，EPDSCH)，或者为物理下行控制信道(physical downlink conrtol channel，PDCCH)。示例性的，本申请下文中，下行数据信道以用于发送控制信息和/或数据的信道，如PDSCH或PDCCH为例进行说明。
5)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括 一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词，用于区分多个对象，但不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
在通信系统中，终端设备可以执行移动性RRM测量。对于处于RRC空闲态(RRC_IDLE)和RRC非激活态(RRC_INACTIVE)的终端设备，可以根据RRM测量的测量结果进行小区选择/重选(cell selection/reselection)。对于处于RRC连接态(RRC_CONNECTED)的终端设备，可以根据RRM测量的测量结果进行小区切换。
终端设备需要通过接收参考信号以执行RRM测量。目前，可用的参考信号主要有SSB信号和信道状态信息参考信号(channel state information-reference signal，CSI-RS)两种。其中，SSB信号是小区级的信号，因此对于处于RRC空闲态、RRC非激活态和RRC连接态的终端设备皆可以适用。而CSI-RS信号只能由处于RRC连接态的终端设备使用，当终端设备处理RRC连接态时，网络设备可以通过RRC信令为终端设备配置一定的CSI-RS资源用于RRM测量。
由此可见，处于RRC连接态的终端设备既可以基于SSB信号执行RRM测量，也可以基于CSI-RS信号执行RRM测量。通常，可以由网络设备通过RRC信令配置终端设备具体采用何种参考信号进行RRM测量。本申请实施例所提供的通信方法，适用于处于RRC连接态的终端设备，因此本申请实施例中的参考信号既可以是SSB信号，也可以是CSI-RS信号。接下来，以参考信号为SSB信号为例对本申请实施例所提供的通信方法作进一步说明，可以理解，在参考信号为CSI-RS信号时的实现方式也应包含于本申请实施例之中。
SSB信号是网络设备周期性发送的广播信号。如图2所示，在多波束小区的应用场景中，网络设备周期性发送同步信号丛集(SS burst set)，一个SS burst set包括多个SSB信号，该多个SSB信号又分别对应于多个波束，相邻的SSB信号可以在时域上连续，也可以在时域上存在一定间隔，本申请实施例对此并不多作限制。对于多波束小区的应用场景，SSB信号周期指的是SS burst set的周期，一般可以为5ms、10ms、20ms、40ms、80ms和160ms中的任一取值。如图2所示，一个SS burst set位于一个无线帧(radio frame)的前半帧或者后半帧，而一个无线帧的长度为10ms，也就是说，网络设备在5ms的时间长度内发送一个SS burst set，一个SS burst set中包括多个SSB信号，且这些SSB信号可以分别对应于不同发射方向的波束。
针对基于SSB信号的RRM测量，网络设备通常会为终端设备配置用于执行RRM测量的测量资源。如图3所示，网络设备为终端设备配置SSB测量时间配置(SS/PBCH block measurement time configuration，SMTC)信息，SMTC信息中包括网络设备为终端设备配置的SMTC周期、偏移值、测量窗时间长度(SMTC window duration)等。
其中，SMTC周期用于指示终端设备可执行RRM测量的时间间隔长度。目前SMTC周期可以为5ms、10ms、20ms、40ms、80ms和160ms中的任一取值，SMTC信息中的偏移值用于指示SMTC测量窗的偏移值，终端设备可以根据测量窗时间长度、偏移值和SMTC 周期，确定网络设备为其分配的可以用来执行RRM测量的时间段，该时间段即为SMTC测量窗，SMTC测量窗的时间长度可以为1ms、2ms、3ms、4ms和5ms中的任一取值。
在SMTC测量窗内每4个时域符号的资源可以构成一个测量位置，一个测量位置与网络设备在SSB信号周期内发送的一个SSB信号相对应。例如，SMTC测量窗内存在一测量位置a，测量位置a与网络设备发送的SSB信号A相对应，则终端设备在测量位置a上可以通过接收SSB信号A执行RRM测量。
可以理解，由于一个SS burst set中相邻SSB信号可以在时域上连续，也可以在时域上不连续，因此在SMTC测量窗内相邻的两个测量位置可以在时域上连续，也可以存在一定间隔，为了便于区分，本申请实施例以SSB符号特指SMTC测量窗内测量位置上的时域符号，以数据符号特指SMTC测量窗内不属于测量位置的时域符号。
需要注意的是，数据符号和SSB符号的子载波间隔(subcarrier spacing,SCS)可以相同，也可以不同。当数据符号和SSB符号的子载波间隔相同时，一个SSB符号和一个数据符号的时间长度相同，当数据符号和SSB符号的子载波间隔不相同时，一个SSB符号和一个数据符号的时间长度不相同。
当配置了SMTC信息时，终端设备只可以在SMTC周期内的SMTC测量窗中执行RRM测量，也就是说终端设备只可以在SMTC测量窗内的测量位置上执行RRM测量。如图3所示，一个SMTC周期内有一个SMTC测量窗，对于相邻的两个SMTC测量窗，前一个SMTC测量窗的首个时域符号与后一个SMTC测量窗的首个时域符号之间间隔即为SMTC周期。
在一种可能的实现方式中，网络设备还可以为终端设备配置SSB位图(SSB-ToMeasure)。SSB位图可以指示SMTC测量窗中终端设备可以执行RRM测量的测量位置。以图4为例，在一个SMTC测量窗中，存在4个参考信号的发送机会，也就是说该SMTC测量窗中最多存在四个测量位置S1至S4。在一种可能的实现方式中，网络设备可以向终端设备发送SSB-ToMeasure，以指示终端设备可以在其中的哪几个测量位置上执行RRM测量。通常，SSB-ToMeasure可以以比特位图(bitmap)的形式表示，该比特位图也可以称为SSB位图，其中的每一位对应SMTC测量窗内存在的一个测量位置，如在图4所示的情况下，SSB-ToMeasure共有四个比特位，这四个比特位分别对应SMTC测量窗中存在的四个测量位置，用于指示终端设备是否可以在对应的测量位置上执行RRM测量。
例如，若SSB-ToMeasure为0101，则终端设备可以在测量位置S2和测量位置S4上执行RRM测量。需要指出的是，即使网络设备向终端设备指示了不可以在某一个测量位置上执行RRM测量，也并不意味着网络设备没有发送该测量位置对应的SSB信号。例如，虽然“0101”中第一个比特位为“0”，但网络设备仍可能会发送测量位置S1对应的SSB信号。
可以理解，若网络设备未为终端设备配置SSB位图，则终端设备可以在SSB测量窗的所有可能存在的测量位置上执行RRM测量。也就是说，当网络设备配置了SSB位图(SSB-ToMeasure)时，SSB位图指示的测量位置即为网络设备为终端设备分配的测量位置，如果网络设备没有配置SSB位图(SSB-ToMeasure)，则SSB测量窗内所有的测量位置皆为网络设备为终端设备分配的测量位置。为了便于表述，在未特别说明的情况下，本申请实施例下述“测量位置”皆特指网络设备分配给终端设备的测量位置，对于其它SMTC测量窗内可能存在但网络设备并未分配给终端设备的测量位置，网络设备可以在这些测量 位置上正常调度终端设备，因此本申请实施例可以不对其予以考虑，这些未分配给终端设备的测量位置也并不会影响到本申请实施例的实现。
由上述SMTC信息可见，网络设备在一个SMTC测量窗内往往会为终端设备配置多个测量位置。然而，这种配置方式会造成对终端设备的调度限制，也就是会对信道资源造成浪费。具体来说，终端设备在受到调度限制的时频位置上，既不期待发送物理上行控制信道(physical uplink control channel，PUCCH)PUCCH/物理上行共享信道(physical uplink shared channel，PUSCH)/探测参考信号(sounding reference signal，SRS)，也不期待接收PDCCH/PDSCH/追踪参考信号(tracking reference signal，TRS)以及用于信道质量指示(channel quality indicator，CQI)测量的CSI-RS。
值得注意的是，终端设备是在满足测量要求(比如测量准确度、最少测量的参考信号数量)的情况下在网络设备为其分配的测量位置上自行决定是否执行RRM测量。为了避免干扰终端设备的RRM测量，网络设备会停止在所有为终端设备分配的测量位置上调度终端设备，因此便造成了信道资源浪费。
以下，对可能存在调度限制的场景作进一步说明：
RRM测量包括对当前为终端设备提供服务的服务小区的测量、对该服务小区的同频邻小区的测量和对该服务小区的异频邻小区的测量。在对同频邻小区测量时，往往会出现调度限制。
具体来说，基于SSB信号的同频邻小区的RRM测量可以定义为：目标邻区的SSB信号和服务小区的SSB信号的中心频率(center frequency)相同，且两个SSB信号的子载波间隔(subcarrier spacing，SCS)也相同。但是，当SSB信号和服务小区的PDSCH/PDCCH的子载波间隔不同，或者终端设备工作在频段2(frequency range2)时，便会存在如下描述的调度限制：
场景1、对于频段1(frequency range1，FR1)，若SSB信号和服务小区的PDSCH/PDCCH的子载波间隔相同，则终端设备不存在调度限制。若SSB信号和服务小区的PDSCH/PDCCH的子载波间隔不同，则是否存在调度限制取决于终端设备的能力。具体来说，若终端设备支持同时接收具有不同SCS的数据和SSB信号(即终端设备支持simultaneousRxDataSSB-DiffNumerology)，则不存在调度限制。若终端设备不支持同时接收具有不同SCS的数据和SSB信号，则会存在以下调度限制：
1a、如果同频邻小区和服务小区是已完成时间对齐的同步小区，则在SMTC测量窗内的所有测量位置上存在调度限制。此外，与测量位置相邻的之前和之后各一个数据符号的时间长度上存在调度限制，以作为测量位置的时间冗余。
1b、如果同频邻小区和服务小区是未完成时间对齐的异步小区，则终端设备在SMTC测量窗内的所有时域符号上都有调度限制。
若终端设备被配置了同频带(intra-band)内的载波聚合(carrier aggregation，CA)，则在该频段内的所有小区都会存在1a和1b中的调度限制。
场景2、对于频段2(frequency range2，FR2)，由于终端设备在执行RRM测量时可以进行接收波束扫描，因此无论终端设备是否支持同时接收具有不同SCS的数据和SSB信号，终端设备在测量同频邻小区时都会存在以下调度限制：
2a、终端设备在SMTC测量窗内的所有测量位置，以及与测量位置相邻的之前和之后 各一个时域数据符号上有调度限制。
在FR2频段内，终端设备无论是被配置了同频带内的载波聚合，还是被配置了不同频带之间的载波聚合，终端设备在所有小区都会受到2a中的调度限制。
由于上述调度限制的存在，减少了网络设备对终端设备的调度机会，对终端设备的吞吐量和调度时延有较大影响。而在CA场景下问题更严重，例如对于同频带内的载波聚合，终端设备在该频带内的所有服务小区都受到调度限制。
接下来，以调度限制对终端设备连接态下的不连续接收(connected-discontinuous reception，C-DRX)产生的影响为例，作进一步说明：
处于RRC连接态的终端设备可能会配置有C-DRX。如图5所示，终端设备配置有DRX循环周期(DRX cycle)。一个DRX cycle中包括DRX持续期(DRX on duration)和DRX休眠期(opportunity for DRX)。终端设备处于DRX on duration时，可以收发数据，而终端设备处于opportunity for DRX，则不监听PDCCH，从而可以降低终端设备的功耗。
具体来说，配置有C-DRX的终端设备主要存在以下两种状态：DRX激活态(DRX active time)和DRX非激活态(DRX non-active time)。在DRX持续期内，终端设备为DRX激活态，终端设备可以持续监听PDCCH，在DRX休眠期内，终端设备为DRX非激活态，终端设备不再监听PDCCH。
通常，终端设备中可以配置多个定时器，以控制终端设备状态切换。当以下任意一个定时器在运行时，终端设备即处于DRX激活态，这些定时器包括：DRX持续期定时器(drx-OndurationTimer)、DRX非激活态定时器(drx-InactivityTimer)、DRX下行重传定时器(drx-RetransmissionTimer DL)，DRX上行重传定时器(drx-RetransmissionTimer UL)，随机接入竞争解决定时器(ra-ContentionresolutionTimer)。
以图5所示的DRX cycle为例，在DRX cycle中的DRX on duration内，终端设备开启定时器drx-OndurationTimer，从而进入DRX激活态。如果在从DRX on duration内，终端设备收到PDCCH指示新的下行或上行数据传输，终端设备会开启(或重启)定时器drx-InactivityTimer，在定时器drx-InactivityTimer运行期间，终端设备仍然处于DRX激活态，终端设备会持续监听PDCCH，直到定时器drx-InactivityTimer超时，终端设备进入DRX非激活态。如果在从DRX on duration内，终端设备未收到PDCCH指示新的下行或上行数据传输，则在drx-OndurationTimer超时后，终端设备进入opportunity for DRX，即终端设备进入DRX非激活态。
目前，第三代合作伙伴计划(3rd generation partnership project，3GPP)有可能会在NR中引入一个新的功率节省信号(power saving signal)。以降低终端设备的功耗。示例性的，该power saving signal可以在DRX cycle开始之前发送，以指示接下来的一个或多个DRX cycle是否需要进入DRX激活态以监听PDCCH。
具体而言，根据不同的功能可以将power saving signal分为唤醒信号(wake-up signal，WUS)和睡眠信号(go-to-sleep signal，GTS)。若power saving signal为WUS信号，则终端设备可以通过是否检测到该信号以确定是否唤醒从而进入DRX激活态。如图6所示，如果终端设备在DRX cycle开始之前检测到WUS信号，则终端设备在接下来的DRX cycle中开启drx-OndurationTimer，从而在DRX on duration内监听PDCCH。如果终端设备在DRX cycle开始之前未检测到WUS信号，则终端设备在接下来的DRX cycle中不开启 drx-OndurationTimer，即终端设备不需要在接下来的DRX cycle唤醒，而保持睡眠状态节省功耗。
若power saving signal为GTS信号，则终端设备在DRX cycle开始之前，如果检测到该GTS信号，则在接下来的DRX cycle中不开启drx-OndurationTimer，从而保持睡眠状态。如果未检测到该GTS信号，则默认在接下来的DRX cycle中开启drx-OndurationTimer，从而在DRX on duration监听PDCCH。
此外，power saving signal也可以通过DCI中特定指示位实现，例如，特定指示位的值为“1”时，指示终端设备在接下来的DRX cycle的DRX on duration内唤醒，特定指示位的值为“0”时，指示终端设备在接下来的DRX cycle的DRX on duration内保持睡眠。
此外，在DRX active time，网络设备也可以发送power saving signal指示终端设备跳过一段时间的PDCCH检测、或者停止drx-InactivityTimer和drx-OndurationTimer、或者进入DRX非激活态等。
虽然power saving signal的具体实现方式、功能等存在多种可能，但一般都是需要通过PDCCH信道发送power saving signal的。在存在调度限制的情况下，若发送power saving signal的资源刚好位于存在调度限制的测量位置，则网络设备会延迟发送power saving signal，直至调度限制解除后再向终端设备发送power saving signal。进而使得终端设备无法及时接收power saving signal，在一些情况下，这会导致DRX激活态的终端设备无法及时进入DRX非激活态，因此不利于进一步降低终端设备的功耗。
另外，调度限制还会延长网络设备调度终端设备的总时间，使终端设备处于DRX active time的时间延长，增加了终端设备的功耗。如果网络设备在受到调度限制的测量位置也可以调度终端设备，那么网络设备就可以尽快的完成数据调度，从而网络设备可以尽早的给终端设备发送MAC CE信令或power saving signal信令使终端设备进入睡眠状态以节省功耗。
此外，在NR的终端设备降功耗(UE power saving)研究中，倾向于对RRM测量进行一定的放松从而节省终端设备执行RRM测量的功耗，比如增大RRM测量的测量周期，又比如减少RRM测量的SSB信号数量等。因此，终端设备将可能在更多的测量位置上并没有执行RRM测量，更加降低了资源的利用率。
综上所述，网络设备和终端设备之间的调度限制降低了信道资源的利用率，并进一步造成了终端设备功耗增加等问题。有鉴于此，本申请实施例提供了一种通信方法，其中，终端设备可以预先确定在接下来的一段时间内用于执行RRM测量的测量位置，并通过向网络设备发送指示信息，以解除网络设备在部分或全部测量位置上的调度限制，从而提高信道资源利用率。
图7示例性示出了本申请实施例提供的通信方法流程示意图，如图7所示，主要包括以下步骤：
步骤701：终端设备根据第一时间段内的多个测量位置确定限制位置。其中，限制位置包括终端设备在第一时间段内用于执行RRM测量的目标测量位置。
以图4为例，假设终端设备确定在测量位置S2上执行RRM测量，则测量位置S2即为目标测量位置。具体而言，终端设备可以按照多种方式确定目标测量位置，例如终端设备可以根据历史测量结果、RRM测量周期、功耗情况等因素确定用于执行RRM测量的目标测量位置，又例如，终端设备也可以根据预设的RRM配置，确定用于执行RRM测量的 目标测量位置，等等，本申请实施例对此并不多作赘述。
在本申请实施例中，终端设备所确定的限制位置至少可以有以下三种具体的实现方式：
实现方式1：限制位置为目标测量位置。例如，目标测量位置为测量位置S2，则限制位置为测量位置S2。
实现方式2：限制位置为目标测量位置、目标测量位置之前的一个数据符号的时间长度和目标测量位置之后的一个数据符号的时间长度。其中，目标测量位置之前的一个数据符号的时间长度和目标测量位置之后的一个数据符号的时间长度可以作为目标测量位置的时间冗余，用于终端设备在执行RRM测量和收发其它数据之间切换处理能力，例如切换子载波间隔，或者是降低相邻时域符号上可能存在的其它调度过程对目标测量位置上的RRM测量的干扰。
需要指出的是，任一目标测量位置(如测量位置A)之前或之后的时域符号既可能是SSB符号，也可能是数据符号。例如，测量位置A之后的时域符号为四个SSB符号，该四个SSB符号构成了测量位置B。假设一个数据符号的时间长度两倍于SSB符号的时间长度，则测量位置B中的前两个SSB符号也会存在调度限制，也就是说，终端设备所确定的限制位置中还包括测量位置B的前两个SSB符号。
除了一个数据符号的时间长度以外，在限制位置中，目标测量位置前后的时段还可以为其他时间长度，以实际符合终端设备的能力的时间冗余为准，本申请对此不作限制。此外，限制位置中目标测量位置前后的时段的时间长度可以不同，甚至可以仅在目标测量位置前面存在时段，或者仅在目标测量位置后面存在时段。
实现方式3：限制位置为目标测量位置所在的测量窗。本申请实施例以SMTC测量窗为例，假设一个SMTC测量窗(如SMTC测量窗a)中存在一测量位置为目标测量位置，则该SMTC测量窗a便为限制位置。
在具体实现过程中，终端设备可以根据网络配置情况灵活选择确定限制位置的具体实现方式。
需要指出的是，本申请实施例中的多个测量位置指的是网络设备为终端设备配置的、终端设备可以在第一时间段内使用的测量位置。在未特别说明的情况下，后续“多个测量位置”皆为此含义，对此不再赘述。
步骤702：终端设备向网络设备发送指示信息。
在本申请实施例中，指示信息可以向网络设备指示多个测量位置中的可用测量位置，网络设备可以使用可用测量位置调度终端设备。
步骤703：网络设备根据指示信息确定多个测量位置中的可用测量位置。
在本申请实施例中，网络设备在确定了多个测量位置中的可用测量位置之后，由于解除了可用测量位置上的调度限制，因此不需要再为可用测量位置预留一定的时间冗余，也就是说，网络设备在可用测量位置之前的一个数据符号的时间长度内，以及在可用测量位置之后的一个数据符号的时间长度内，也可以解除调度限制。
在一种可能的实现方式中，网络设备还可以确定是否使用可用测量位置，即是否在可用测量位置上解除调度限制，并向终端设备发送控制指令。例如，若网络设备确定在可用测量位置上解除调度限制，则可以通过发送L1信令/媒体介入控制单元(medium access control channel element，MAC CE)/RRC信令指示终端设备。若终端设备在发送指示信息之后的一段时间内没有收到网络设备发送的控制指令，则终端设备认为调度限制仍然适用 于可用测量位置。
在另一种可能的实现方式中，还可以默认以终端设备上报指示信息为准。例如，网络设备在接收到指示信息后，确认在可用测量位置上解除调度限制，并向终端设备返回接收应答，终端设备在接收到接收应答后，确认网络设备已在可用测量位置上解除调度限制。
至此，网络设备在调度终端设备时，便可以根据终端业务的需求在可用测量位置上调度终端设备。以上述C-DRX为例，若网络设备发送GTS信号的时机落在了可用测量位置上，则网络设备便可以在可用测量位置上发送GTS信号。由此可见，采用图7所示的通信方法，既可以避免(或较小地)干扰终端设备的RRM测量，又有利于提高信道资源利用率。
接下来，以实施例一至五为例，对本申请实施例所提供的通信方法作进一步说明：
实施例一
在本申请实施例中，可以有多种触发终端设备执行上述步骤701和步骤702的实现方式。示例性的，至少存在以下两种实现方式：
方式1、网络设备向终端设备发送上报指令，以指示终端设备上报指示信息。
具体来说，该上报指令可以是现有的、网络设备常在开启下行数据传输之前发送的指令，例如以C-DRX场景为例，该上报指令可以是指示终端设备在接下来的一个DRX cycle内唤醒的power saving signal，也可以是DRX On Duration内的第一个调度新的上行/下行传输的PDCCH消息。
以DRX On Duration内的第一个调度新的上行/下行传输的PDCCH消息为例，终端设备在收到该消息后，便往往意味着网络设备启动了向终端设备发送下行消息或者调度终端设备发送上行消息。在此情况下，终端设备向网络上报指示信息，使网络设备可以根据上报的指示信息确定可用测量位置，并在可用测量位置上解除调度限制，有利于提高后续下行或上行消息的传输速率。
可以理解，该上报指令也可以是新增的、可以指示终端设备上报指示信息的指令。网络设备可以在向终端设备发送指示调度新的上行/下行传输的PDCCH之前发送该指示信息，使终端设备上报指示信息。进而，可以根据上报指示信息，确定可用测量位置，并在可用测量位置上发送下行或上行消息。
在本申请实施例中，上报指令既可以隐性触发终端设备上报指示信息，也可以显性触发终端设备上报指示信息。具体来说，在隐性触发的实现方式中，终端设备默认接收到特定的下行消息(上报指令)后，便触发执行步骤701和步骤702。例如，终端设备默认在收到指示唤醒的唤醒信号(wake up signal)或者第一个调度新传的PDCCH消息之后，便触发执行步骤701和步骤702。在显性触发的实现方式中，上报指令中携带指令信息，该指令信息可以指示终端设备是否上报指示信息。例如，上报指令为wake up signal或者为第一个调度新传的PDCCH的DCI消息，上报指令中的某一比特域(例如，1个bit)指示终端设备是否上报指示信息。
方式2、终端设备主动上报指示信息。
具体来说，网络设备可以半静态地为终端设备配置上报周期，以使终端设备可以按照上报周期主动周期性上报指示信息。例如，现有协议在RRM测量配置时可以配置终端设 备周期性上报RRM测量结果，即在上报配置(ReportConfigNR)中配置，其中的上报间隔(reportInterval)表示上报周期。有鉴于此，可以按照现有的协议，使终端设备在周期性上报RRM测量结果的同时，上报指示信息，以指示网络设备在接下来的上报周期内的可用测量位置。在此情况下，接下来的上报周期便可以为上述第一时间段。
此外，终端设备也可以在确定执行到特定行为时上报指示信息。例如，终端设备在启动drx-InactivityTimer时，触发上报指示信息。在C-DRX中，终端设备通常在接收到第一个调度新传的PDCCH消息之后会开启drx-InactivityTimer，因此在终端设备启动drx-InactivityTimer时，便往往意味着网络设备会继续向终端设备发送下行消息或者终端设备向网络设备发送上行消息。在此情况下，终端设备向网络上报指示信息，使网络设备可以根据上报信息确定可用测量位置，并在可用测量位置上解除调度限制，有利于提高后续下行消息的传输速率。
实施例二
终端设备在上报指示信息时，需要占用一定的上行资源。在本申请实施例中，网络设备即可以为终端设备半静态地配置用于发送指示信息的上行资源，也可以为终端设备动态地配置用于发送指示信息的上行资源。具体来说，至少存在以下四种可能的实现方式：
方式1、在终端设备主动上报指示信息的情况下，终端设备可以主动向网络设备请求上行资源。
具体来说，终端设备在确定需要上报指示信息之后，可以先向网络设备发送请求消息以请求网络设备为指示信息分配上行资源。网络设备在接收到请求消息后为指示信息分配上行资源并向终端设备返回应答消息。终端设备根据应答消息确定网络设备为指示信息分配的上行资源，并在该上行资源上发送指示信息。
以C-DRX为例，终端设备可以在DRX on duration内或者DRX active time内通过发送调度请求(scheduling request，SR)，以向网络设备请求分配用于发送指示信息的上行资源。
方式2、网络设备为上报指令分配关联的上行资源，并向终端设备发送配置信息，该配置信息可以用于配置上报指令与上行资源之间的关联关系。
例如，网络设备可以半静态配置与上报指令关联的上行资源，该上行资源可以是PUCCH资源或者PUSCH资源，网络设备向终端设备发送的配置信息中包括上行资源的时/频域配置参数(例如，频域起始位置，频域带宽，时域时隙数量，时隙中符号位置等)，以及与上报指令的时间偏移(offset)。终端设备在收到上报指令后，即可以根据配置信息确定指示信息关联的上行资源，进而可以在指示信息关联的上行资源上发送指示信息。
此外，上报指令中还可以包括一指示参数，该指示参数可以用于指示终端设备是否在指示信息关联的上行资源上发送信息，从而可以更加灵活地调度终端设备上报指示信息。
方式3、与方式2相类似，区别在于可以由上报指令中携带上述时间偏移。
方式4、上报指令中直接指示用于发送指示信息的上行资源，终端设备可以在上报指令指示的上行资源上发送指示信息。
实施例三
在本申请实施例中，网络设备可以根据指示信息确定第一时间段内，多个测量位置中的可用测量位置。在一种可能的实现方式中，指示信息可以指示第一时间段。具体而言， 终端设备可以上报第一时间段的指示信息，例如可以上报一时间长度，网络设备可以将接收到终端设备的指示信息的时刻作为第一时间段的起始时刻，进而确定第一时间段。或者，指示信息可以显性指示第一时间段的起始时刻。在另一种可能的实现方式中，若终端设备配置了周期性上报，则网络设备可以默认该指示信息指示的是接下来的一个上报周期(即第一时间段)内的可用测量位置。
在本申请实施例中，指示信息可以有多种实现方式，示例性的，指示信息至少可以有以下几种实现方式：
方式1、在多个测量位置中存在至少一个限制位置的情况下，指示信息用于指示至少一个限制位置，或者用于指示上述可用测量位置。
如前所述，限制位置既可以是目标测量位置(以及目标测量位置之前和之后的各一个数据符号的时间长度)，也可以是目标测量位置所在的测量窗，接下来分情况进行说明。
在限制位置为目标测量位置的情况下：
在一种可能的实现方式中，网络设备在为终端设备配置多个测量位置时，还可以为多个测量位置分配对应的标识信息(SSB index)。若终端设备向网络设备上报的指示信息中包括目标测量位置对应的标识信息，网络设备便可以根据目标测量位置对应的标识信息，确定多个测量位置中的目标测量位置，进而便可以确定多个测量位置中除目标测量位置之外的测量位置，即可用测量位置。若终端设备向网络设备上报的指示信息中包括可用测量位置的标识信息，则网络设备便可以根据可用测量位置的标识信息直接从多个测量位置中确定可用测量位置。
在另一种可能的实现方式中，终端设备还可以基于网络设备配置的SSB-ToMeasure，以指示位图(SSB-ActuallyToMeasure)的形式上报指示信息，该指示位图可以与SSB-ToMeasure具有相同的位数。以图4为例，网络设备为终端设备配置的SSB-ToMeasure为0101，指示终端设备配置有2个测量位置：S2和S4。假设终端设备确定测量位置S4为目标测量位置，测量位置S2为可用测量位置，则终端设备可以向网络设备上报指示位图：0001。网络设备在接收到指示位图后，便可以根据指示位图确定测量位置S2为可用测量位置，测量位置S4为限制位置。
在限制位置为目标测量位置所在的测量窗的情况下：
在一种可能的实现方式中，终端设备上报的指示信息中可以包括目标测量位置所在的至少一个测量窗的标识信息，或者，指示信息包括可用测量位置所在的至少一个测量窗的标识信息。若指示信息中包括目标测量位置所在的至少一个测量窗的标识信息，则网络设备便可以在第一时间段内不执行RRM测量的测量窗解除调度限制，不执行RRM测量的测量窗中的测量位置即为可用测量位置。若指示信息中包括可用测量位置所在的至少一个测量窗的标识信息，网络设备便可以根据该至少一个测量窗的标识信息确定对应的至少一个测量窗，进而确定该至少一个测量窗中的测量位置为可用测量位置。
例如，终端设备指示网络设备在成功收到指示信息之后的第N个SMTC测量窗为目标测量位置所在的测量窗，即终端设备在第N个SMTC测量窗要执行RRM测量，而在第一时间段的其它SMTC测量窗内终端设备不执行RRM测量。
另外，可以理解的是，如果网络设备根据终端设备发送的指示信息确定一个测量窗为限制位置，则该测量窗内的调度限制根据服务小区和同频邻区是否同步来确定，即如果同频邻小区和服务小区是同步的，则该测量窗内的调度限制包括网络设备配置给终端设备的 测量位置和测量位置前后的各一个数据符号的时间长度，如果同频邻小区和服务小区是非同步的，则该测量窗内的调度限制包括该测量窗内所有时域符号，如果网络设备根据终端设备发送的指示信息确定一个测量窗为非限制位置，也就是该测量窗内的测量位置均为可用测量位置(非目标测量位置)，则该测量窗内的所有时域符号都会被解除调度限制，即网络设备可以在该测量窗内的任意时域符号调度终端设备。
在本申请实施例中，目标测量位置所在的至少一个测量窗的标识信息也可以是比特位图。具体来说，比特位图包括M个比特位，从比特位图的首位至末位，依次与第一时间段内的第一个测量窗至最后一个测量窗相对应，比特位图中的每一位用于指示对应的测量窗是否为限制位置。例如，在第一时间段内共存在5个测量窗，其中第一个和第三个测量窗为限制位置，则该比特位图可以为10100，其中1表示目标测量位置所在的测量窗(即限制位置)，0表示可用测量位置所在的测量窗。
方式2、在多个测量位置中存在至少一个限制位置的情况下，指示信息用于指示至少一个第二时间段，该至少一个第二时间段为第一时间段内除至少一个限制位置之外的全部或部分时间段。
以图3为例，假设第一时间段包括4个SMTC周期，若终端设备确定第一个SMTC测量窗为限制位置，则第二时间段包括第一个SMTC测量窗之后的第一个时域符号、第一时间段最后一个时域符号及两个时域符号之间间隔的其它时域符号。网络设备在接收到指示信息后，可以确定该至少一第二时间段中的测量位置为可用测量位置，从而可以在该至少一个第二时间段上调度终端设备。
在只有一个第二时间段的情况下，指示信息中可以包括一时间长度，网络设备可以将接收到指示信息的时刻作为第二时间段的起始时刻，并基于该时间长度确定第二时间段，或者指示信息也可以直接指示第二时间段的起始时刻。
在有多个第二时间段的情况下，指示信息中可以包括各个第二时间段的时间长度，以及各个第二时间段的起始时间点，网络设备可以根据各个第二时间段的时间长度，以及各个第二时间段的起始时间点分别确定多个第二时间段。
可以理解，终端设备也可能在第一时间段内并不执行RRM测量，即不存在目标测量位置。在此情况下，终端设备发送的指示信息还可以指示第一时间段。网络设备在接收到指示信息后，便可以确定其在第一时间段内为终端设备分配的所有测量位置皆为可用测量位置。
实施例四
接下来，以一具体实施例对本申请实施例所提供的通信方法作进一步说明。如图8所示，图中的小方格代表一个SMTC测量窗，SMTC周期为20ms。
如图8中，终端设备执行RRM测量的测量周期为200ms，即终端设备需要每200ms获得至少一个层3滤波(layer 3 filtering)之后的RRM测量结果。终端设备通过其它power saving技术决定将测量周期从200ms增大到800ms。比如终端设备判断出信号质量(例如，参考信号接收功率(reference signal received power，RSRP))高于一定阈值，或者终端设备判断出自身移动性较低，或者终端设备判断出离小区边缘较远等，这些情况下RRM测量结果较为稳定，则终端设备可能会增大测量周期，以减少RRM测量次数。
由于终端设备有可能会自行调节RRM测量的测量周期，致使网络设备无法确定终端 设备具体在哪一个SMTC测量窗内执行了RRM测量，因此在所有的测量位置上都存在调度限制。
在本实施例四中，上报指令为WUS信号，网络设备提前通过配置信息为WUS信号半静态配置了关联的上行资源。在配置信息中包括上行资源的时/频域配置参数，例如，频域起始位置，频域带宽，时域时隙数量，时隙中符号位置等。
在接收到WUS信号之前，终端设备保持休眠态。终端设备接收到WUS信号后，根据WUS信号在下一个DRX cycle内唤醒。WUS信号还指示了一个时间偏移(offset)，终端设备可以根据配置信息和时间偏移，确定用于发送指示信息的上行资源。终端设备在WUS信号关联的上行资源上上报指示信息，该指示信息可以包括：一个时间长度，时间长度为上述第二时间段的时间长度，如图8中第二时间段T的时间长度为130ms。网络设备默认成功收到该指示信息的时刻为第二时间段T的起始时刻，从而可以根据时间长度确定第二时间段T。
如图8所示，终端设备在第二时间段T内不执行针对服务小区和同频邻区的RRM测量。所以网络设备可以在第二时间段T内的测量位置上解除调度限制，即确定第二时间段T内的测量位置为可用测量位置，从而可以在第二时间段T内调度终端设备。
实施例五
接下来，以另一具体实施例对本申请实施例所提供的通信方法作进一步说明。如图9所示，在第一时间段内存在多个SMTC测量窗，网络设备向终端设备发送的SSB-ToMeasure为1111，即网络设备将SSB1至SSB4皆分配给终端设备执行RRM测量。但终端设备根据历史测量结果等信息，可能只选择在SSB1和SSB2这两个目标测量位置上执行RRM测量。在此情况下，终端设备便可以上报指示信息(如1100)，以指示网络设备在接下来的第一时间段内，可以在每个SMTC测量窗的SSB3和SSB4上调度终端设备。
可以理解，本申请实施例中指示信息的具体实现方式存在多种可能，且不同实现方式之间可以互相结合。例如，指示信息既可以指示第二时间段，又可以指示限制位置。以实施例四和实施例五为例，网络设备可以根据指示信息确定可以调度终端设备的第二时间段，同时，对于第一时间段内除第二时间段之外的时间段，这些时间段中的SMTC测量窗可以认为是用于执行RRM测量的SMTC测量窗。对于用于执行RRM测量的SMTC测量窗，则可以根据比特位图“1100”确定限制位置为用于执行RRM测量的SMTC测量窗中的SSB1和SSB2，从而可以进一步缩小限制位置的范围，增加调度终端设备的机会。
