Description

一种数据处理方法及其设备
本申请要求于2020年11月30日提交中国专利局、申请号为202011377376.6、申请名称为“一种数据处理方法及其设备”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，具体涉及一种数据处理方法及其设备。
背景技术
5G市场的定位需求中，往往有很多对于物的定位(资产管理设备、设备监控等)。对于物的定位是需要极地功耗要求的，通常需要终端设备满足长期使用的情况下不充电，不更换电池。
5G标准在R16版本中，定义了高精度定位的标准，但是并不满足这样低功耗的要求。以UTDOA定位为例，定位过程需要服务小区分配SRS资源，终端在RRC连接态发送SRS信号，周边多个基站接收SRS信号进行TOA解算，并上报服务器进行TDOA解算。5G UTDOA定位在定位过程中，终端设备开机后主要分成3个阶段，第一阶段是捕获系统获取系统消息，第二阶段是随机接入和建立RRC连接，第三阶段才是获得SRS配置并周期发送SRS信号。
整个定位期间，需要保持RRC连接，如果RRC连接释放了，需要重新发起随机接入，再次建立RRC连接后，重新发送SRS配置数据，才能发送SRS信号进行定位。因此，为完成周期定位，终端设备将长期处于RRC连接态，终端设备的功耗较高，影响了终端设备基于低功耗的布局。

具体实施方式
本申请实施例提供了一种数据处理方法，终端设备通过在发送第一上行定位信息之后进入休眠模式，在需要发送第二上行定位信息时进入正常模式，并在相同的第二时域位置发送第二上行定位信息，终端设备通过在固定的第二时域位置发送第二上行定位信息，并不需要与基站保持RRC连接，节省了终端设备的功耗。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，为本申请实施例提供的一个现有技术定位流程图。
为了方便本领域技术人员理解本申请实施例，本申请实施例对现有技术中的定位流程作出简单介绍。
如图1所示，终端设备在定位流程中，可分为三个步骤。
第一步，终端设备捕获系统消息。
具体的，终端设备搜索5G网络，捕获PSS/SSS，获得同步定时。终端利用PBCH、PDCCH、PDSCH等信道，读取MIB/SIB等多条系统消息，获得与其相关的参数。
第二步，终端设备建立接入连接。
具体的，终端设备通过PRACH信道发送随机接入前导，基站通过PDCCH和PDSCH信道发送随机接入响应。终端设备通过PUSCH发送连接请求，基站通过PDCCH和PDSCH信道发送RRC连接配置，终端设备通过PUSCH发送RRC配置完成消息。
第三步，终端设备获得SRS周期，并发送SRS。
具体的，基站通过PDCCH和PDSCH信道发送RRC重配置消息(即周期SRS配置消息)，终端设备通过PUSCH信道发送RRC重配置完成消息。在终端设备完成RRC重配置之后，终端设备可以在SRS资源符号位置，按照SRS配置的周期和带宽等，周期性的发送SRS信号，该SRS信号用于基站进行TOA定位。
现有技术中，终端设备和基站在进行定位的过程中，几乎把5G系统的所有上下行物理信道都使用了，不算RRC数据传输使用的DMRS等隐性的参考信号外，显性的参考信号也使用了3个，上下行的物理信道使用了5个。而且，为了完成周期定位，终端设备将长期处于RRC连接态，无法休眠，不能很好的满足低功耗的要求。
为了解决上述问题，本申请实施例提供了一种数据处理方法，可以使得终端设备在不发送定位消息时进入休眠状态，节省了终端设备的功耗，并且简化了空口的交互流程，降 低了基站和终端设备的交互时间。
下面，对本申请实施例的低功耗定位系统架构进行介绍。
请参阅图2，为本申请实施例提供的低功耗定位系统架构图。
如图2所示，该低功耗定位系统架构中包括至少一个定位终端201，至少一个定位基站202，和至少一个定位解算服务器203。其中，定位终端202即为终端设备，定位基站202即为基站。可以理解的是，本申请实施例中，还可以包括更多的定位终端201、定位基站202和定位解算服务器203。
定位终端201和定位基站202可以通过无线网络连接。具体的，该无线网络连接可以包括第五代(5th generation，5G)移动通信网络、5G NR网络，或者其他未来的新型移动通信网络等。该无线网络连接还可以是同时支持多种无线技术的通信网络，例如同时支持LTE和NR的通信网络；或者，该无线网络连接还可以是支持近距离通信的通信网络，例如，支持侧行链路(sidelink，SL)技术的通信网络，支持无线保真(wireless fidelity，WiFi)技术的通信网络等等。
定位基站202和定位解算服务器可以通过有线网络连接或者无线网络连接。有线网络连接可以是光纤连接等。无线网络连接和上述定位终端201与定位基站202的无线网络连接类似，具体此处不再赘述。
定位基站202可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)等，或者其他未来移动通信系统中的基站，具体本申请实施例对此不作限定。
定位终端201可以是一种用于接收或发射信号的实体，如手机。定位终端201也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。定位终端201可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、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)中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
需要说明的是，本申请实施例中定位终端201通常做成标签的形态，所有有时也可以称定位终端201为定位标签。
定位解算服务器203负责进行定位终端201的位置解算，定位终端201的定位结果在该定位解算服务器203获得。
定位基站202与定位终端201通信，并完成定位终端201发送定位参考信号的TOA估计。
定位终端201与定位基站202通信，向定位基站202发送定位参考信号，即本申请实施例中的上行定位信息。
为了方便理解，下面对本申请实施例中使用到的名词作出基本解释。
定位需要使用到的信道和信号包括：PSS/SSS、PBCH、PDCCH、PDSCH、PRACH、PUSCH、SRS。其中：
主同步信号(PSS)和辅同步信号(SSS)主要用于UE进行下行的同步系统捕获。
物理广播信道(PBCH)承载系统广播消息，即MIB消息和SIB1的调度信息。
物理下行控制信道(PDCCH)用于上下行的调度和指示其他SIB的位置。
物理下行共享信道(PDSCH)用于承载下行用户数据和其他SIB数据。
物理随机接入信道(PRACH)用于UE发起随机接入请求。
物理上行共享信道(PUSCH)用于UE发送上行用户数据。
Sounding参考信号(SRS)用于进行上行信道测量，TOA估计等。
5G标准的空口帧结构中，有帧、子帧、时隙、符号的概念，信道设计与帧结构密切相关，具体概念描述如下。
帧：Frame，一个帧的持续时长是10ms。
子帧：Sub Frame，1个子帧时长是1ms，1帧含10个子帧。
时隙：Slot，时隙的时长与子载波间隔相关，1个子帧中：15k子载波时有1个时隙，30K子载波时有2个时隙，60K子载波时有4个时隙，以此类推。
符号：Symbol，一个时隙含14个符号。
在实施本申请实施例的方法之前，需要满足一些前提要求。具体下面做详细介绍。
因为本申请实施例用于低功耗定位的信道是独立设计的，所以低功耗定位所使用的5G时域和频域资源需要同5G NR网络进行协商。
例如，通过时域切片的方式获得定位所用的时域资源和频域资源。切分出来给本申请实施例中数据处理方法使用的时域资源和频域资源NR不再使用，以避免相互之间的干扰。NR网络切分哪些资源，切分多少资源给本申请实施例中数据处理方法使用，需要根据实际的业务的容量诉求来规划，但是需要满足低功耗定位的最小资源需求：一帧内，需要至少1个下行符号和2个上行符号。下面示例两个具体的切分方案供参考。
在5G NR的时分双工TDD模式下，存在上下行切换时隙配比。其中，有3种时隙，分别是下行时隙(D)，上行时隙(U)和特殊时隙(S)。其中特殊时隙是上下行切换的时隙，该时隙前面的若干符号是下行符号，后面的若干符号是上行符号，中间会有一些GAP符号(G)，该符号上下行都不使用，作为上下行切换的保护符号。
一、仅使用GAP符号进行切分。
如图3所示，在30K子载波间隔的NR网络中，以一个无线帧(10ms)为周期，切分1个下行符号，5个上行符号给本申请实施例中数据处理方法使用，其中，slot7的符号6用于定位下行符号“PD”，slot7的符号8/9，slot17的符号7/8/9用于定位的上行符号“PU”。
二、使用GAP符号和上行符号进行切分。
如图4所示，在30K子载波间隔NR网络，每10ms分配1个下行符号，14个上行符号给本申请实施例中数据处理方法使用。Slot7的符号6作为定位下行符号“PD”，整个 slot19的14个符号都作为定位的上行符号“PU”。
以上对本实施例的低功耗定位系统架构和前提要求作出了说明，下面对本申请实施例的数据处理方法进行详细说明。
本申请实施例中，以定位终端201为终端设备，定位基站202为基站为例进行说明。
本申请实施例中，可以在一个NR符号中通过频分复用的方式或者通过在一个NR符号中设置多个子符号的方式传输上行数据或者下行数据，本申请实施例将分别进行说明。
一、通过在一个NR符号中设置两个子符号的方式传输上行数据或者下行数据。
请参阅图5，为本申请实施例提供的数据处理方法的一个流程示意图。
在步骤501中，基站向终端设备发送第二下行数据。
在低功耗定位场景中，基站会先通过第三时域位置在下行物理信道PDCH发送第二下行数据，该第二下行数据包括系统消息，该系统消息中携带第四时域位置的信息，该第四时域的位置信息用于指示初始接入信道的符号位置，该第三时域位置为基站和终端设备协议定义的。可以理解的是，在实际应用过程中，该系统消息还可以携带更多的信息，例如该系统信息还可以携带上行定位信息使用的带宽的信息，具体此处不做限定。
如图6所示，本实施例中，在下行信道中设计了1个下行物理信道PDCH，2个逻辑信道：广播信道BCH和下行公共控制信道DCCH。这两个逻辑信道的数据都通过相同的下行物理信道PDCH承载。其中，广播信道用于系统消息的发送，下行公共控制信道用于针对单个终端设备下发控制消息，例如资源分配消息等。
如图7所示，本实施例设计的下行物理信道由循环前缀CP，下行同步参考信号DSS(即下行同步信息)以及下行数据几部分组成。
在一种可能的实现方式中，系统消息中还携带有时间信息，该时间信息用于终端设备进行时间同步。在实际应用过程中，终端设备通过基站发送的同步参考信号DSS实现与基站的频率同步，并通过时间信息实现与基站的时间同步。
本实施例中，通过将PDCH的子载波间隔设置为NR子载波间隔的2倍，使得本实施例中所使用的子符号的时长为NR符号时长的一半，因此，当从NR网络中切分一个目标符号使用时，本实施例可以使用两个子符号来承载数据。例如，NR使用30K子载波间隔，则PDCH采用60K子载波间隔或者120K子载波间隔，则子符号的时长为NR符号时长的一半或者四分之一，即可以将一个目标符号作为两个以上的子符号进行使用。
其中，PDCH采用双符号设计，每个符号都带有循环前缀CP。第一个符号发送下行同步序列DSS，即下行同步信息，用于终端设备捕获系统消息并和基站的时间同步对齐，可选的，该DSS还可以用于信道估计。第二个符号用于发送PDCH承载的数据。
PDCH使用的带宽为某个固定的带宽，例如10Mhz或者20Mhz。
DSS的调制方式采用BPSK的方式。DSS序列采用3GPP标准定义的固定m序列，或者采用低峰均比Low-PARP的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
下行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不 做限定。
PDCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
下行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输下行数据。其中，因为下行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送广播信道，第二个固定周期发送下行控制信道。例如，广播信道在偶数帧发送，下行控制信道在奇数帧发送。下行物理信道按照10ms为一个周期，则广播信道在第一个10ms中使用该NR目标符号，下行控制信道在第二个10ms中使用该NR目标符号。如图8所示，从NR网络中切分出的目标符号为在第7个时隙中的第6个符号，则在帧0中，广播信道使用该目标符号传输系统消息，该帧0中的目标符号即为第三时域位置，在帧3中，下行控制信道使用该目标符号传输资源分配消息。
在步骤502中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的系统消息之后，终端设备根据系统消息通过上行物理信道在第四时域位置向基站发送第二上行数据和第一上行定位信息，该第二上行数据中包括初始接入消息，该初始接入消息用于终端设备进行初始接入。
如图9所示，本实施例中，在上行信道中设计了1个上行物理信道PUCH，2个逻辑信道：接入信道ACH和上行共享信道USCH。这两个逻辑信道的数据都通过相同的上行物理信道承载。其中，接入信道用于发送初始接入消息，上行共享信道用于传输上行数据以及上行定位信息，UTDOA定位就是利用上行定位信息进行TOA的估计。
如图10所示，本实施例设计的上行物理信道由循环前缀CP，低功耗定位参考信号LPRS(即上行定位信息)以及上行数据几部分组成。
本实施例中，通过将PUCH的子载波间隔设置为NR子载波间隔的2倍，使得本实施例中所使用的子符号的时长为NR符号时长的一半，因此，当从NR网络中切分一个目标符号使用时，本实施例可以使用两个子符号来承载数据。例如，NR使用30K子载波间隔，则PUCH采用60K子载波间隔或者120K子载波间隔，则子符号的时长为NR符号时长的一半或者四分之一，即可以将一个目标符号作为两个以上的子符号进行使用。
其中，PUCH采用双符号设计，每个符号都带有循环前缀CP。第一个符号发送低功耗定位参考信号LPRS，即上行定位信息，用于基站进行TOA估计，可选的，该上行定位信息还可以用于上行物理信道的信道估计。第二个符号用于发送PUCH承载的数据。
与PDCH的带宽使用情况不同，PUCH占用的带宽分成两部分。当通过第一个符号发送LPRS时，通常是使用全带宽。发送LPRS时使用全带宽是由于UTDOA定位的精度要求，使用更多的带宽发送更多的LPRS，可以更准确的进行UTDOA定位，进而可以提高UTODA的定位精准度。在实际应用过程中，具体的带宽可以根据NR网络和定位系统的负荷情况进行协商配置，例如只使用其中的部分带宽传输LPRS，具体此处不做限定。
而通过第二个符号发送上行数据时，可以使用某个固定的带宽，例如10Mhz或者20Mhz，因为在定位场景下，需要发送的上行数据较少，因此可以不占用全带宽，节省带宽资源。在实际应用过程中，通过第二个符号发送上行数据时，也可以使用全带宽，具体 此处不做限定。
LPRS的调制方式采用BPSK的方式。LPRS序列可以采用3GPP标准定义的Low-PAPR的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
上行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PUCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
上行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输上行数据。其中，因为上行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送接入信道，第二个固定周期发送上行共享信道。例如，接入信道在偶数帧发送，上行共享信道在奇数帧发送。上行物理信道按照10ms为一个周期，则接入信道在第一个10ms中使用该NR目标符号，上行共享信道在第二个10ms中使用该NR目标符号。如图11所示，从NR网络中切分出的目标符号为在第7个时隙中的第8个符号，则在帧0中，接入信道使用该目标符号传输初始接入消息，该帧0中的目标符号即为第四时域位置，在帧0的第7个时隙中的第9个符号和帧0中的第17个时隙中的第7、8、9个符号中，上行共享信道使用这些目标符号传输定位消息。
在步骤503中，基站向终端设备发送第一下行数据。
当终端设备向基站发送初始接入消息之后，基站在第一时域位置向终端设备发送第一下行数据，该第一下行数据包括了资源分配消息，该资源分配消息中携带了第二时域位置的信息。
可选地，基站还通过该第一时域位置发送下行同步信息，该下行同步信息用于终端设备进行时间同步。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，基站通过在该NR目标符号中发送第一下行数据和下行同步信息。具体的，可以在该NR目标符号的第一子符号中发送下行同步信息，在第二子符号中发送第一下行数据。
本实施例中，因为第一下行数据中包括了资源分配消息，而资源分配消息是根据终端设备的需求进行发送的。例如，当需要给终端设备分配资源时，基站才会在第一下行数据中携带资源分配消息。若终端设备不需要分配资源时，则基站可以在第一时域位置中只发送下行同步信息下行同步信息，不发送资源分配消息。
在步骤504中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的资源分配消息和下行同步信息之后，终端设备根据资源分配消息在第二时域位置发送第二上行数据和第一上行定位信息，该第一上行定位信息用于基站进行到达时间TOA的估计。
具体的，如前述步骤，终端设备可以在通过上行共享信道USCH在第二时域位置中发送第二上行数据和第一上行定位消息，该第二时域位置的信息是携带在基站发送的资源分配消息中的。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符 号，终端设备通过在该NR目标符号中发送第二上行数据和第一上行定位消息。具体的，可以在该NR目标符号的第一子符号中发送第一上行定位消息，在第二子符号中发送第二上行数据。
在实际应用过程中，终端设备发送上行数据的数据量会小一些，且在定位场景下，基站对定位的精准度要求较高。因此，终端设备可以在发送第一上行定位消息时，使用最大带宽，以确保发送更多的第一上行定位消息。而在发送第二上行数据时，可以根据实际的数据量进行调整，若数据量小，则使用较少的带宽发送第二上行数据，可以节省带宽资源。
在步骤505中，终端设备启动定时器，进入休眠模式。
终端设备在发送完第一上行定位消息之后，终端设备可以启动定时器，并在定时器启动之后，进入休眠模式，该休眠模式的功耗低于终端设备处于正常模式下的功耗，该定时器的时长为预设阈值。
具体的，因为终端设备没有和基站之间建立RRC连接，因此终端设备为了保持低功耗状态，可以进入休眠模式。本实施例方法中，终端设备可以通过在基站分配的指定时域资源位置接收下行同步信息和系统消息，用于终端设备与基站进行时间同步，并且接收系统消息。而在其他时间段，则可以进入休眠模式，以便于减少终端设备的功耗。
在步骤506中，当定时器超时，终端设备进入正常模式。
当定时器超时之后，终端设备退出休眠模式，进入正常模式，在正常模式下终端设备可以在基站分配的指定时域资源位置接收下行同步信息和系统消息。例如终端设备可以在第三时域位置接收基站发送的携带有系统消息的第二下行数据。
在步骤507中，终端设备向基站发送第二上行定位信息。
终端设备在进入正常模式之后，终端设备基于与基站的协议约定，在第二时域位置向基站发送第二上行定位信息，该上行定位信息用于基站进行到达时间TOA估计。
具体的，终端设备在进入正常模式之后，终端设备基于基站已经分配的时域资源信息，向基站发送第二上行定位信息。例如，第二时域退出休眠模式，进入正常模式的时间在帧0中的第1个时隙，而基站给终端设备分配的第二时域位置是帧0中的第17个时隙中的第7个符号，则终端设备只需要等待10个时隙与7个NR目标符号的时长，就可以再次向基站发送上行定位信息。因为本实施例中限定了每1个帧中，都会有分配到至少1个NR目标符号用于发送上行定位信息，因此终端设备等待的时间较短，减少了终端设备因等待发送上行定位信息的时域资源而消耗的功耗。
在实际应用过程中，终端设备在发送完第二上行定位信息之后，又可以继续进入休眠模式，以保持低功耗的运行状态。
本申请实施例中，基站和终端设备通过更少的信息交互，就可以实现终端设备和基站之间的数据传输和定位，避免了标准UTDOA定位的复杂流程，并且可以长时间按照基站分配的时域资源周期性的发送上行定位消息，发送完成后又可以立即休眠，以保持终端设备的低功耗状态，节省了终端设备的功耗。
基于前述图1所示的现有技术UTDOA定位流程，本申请实施例中低功耗定位的方法与 现有技术3GPP的标准UTDOA定位流程对比如下表1。
表1低功耗定位的方法与现有技术3GPP的标准UTDOA定位流程对比表
Figure PCTCN2021130642-appb-000001
利用本申请实施例的信道除了可以简化上述R16的标准UTDOA定位流程，终端接收和发送消息的处理时间也明显少于R16标准UTDOA定位流程。本申请实施例的信道时序简单并且周期位置固定，在已经分配的符号进行接收信息和发送信息，持续时长小于1个NR目标符号。而R16标准UTDOA定位流程中，通过PDSCH接收消息时，需要先监听PDCCH信道，而PDCCH的持续时长是1-3个NR目标符号，PDSCH的时长通常是以时隙为单位的。另外，本申请实施例中的信道也无需R16标准L2的HARQ应答机制，减少了终端设备的信号发送次数。
二、通过频分复用的方式在一个NR符号中传输上行数据或者下行数据。
请参阅图5b，为本申请实施例提供的数据处理方法的另一流程示意图。
在步骤601中，基站向终端设备发送第二下行数据。
在低功耗定位场景中，基站会先通过第三时域位置在下行物理信道PDCH发送第二下行数据，该第二下行数据包括系统消息，该系统消息中携带第四时域位置的信息，该第四时域的位置信息用于指示初始接入信道的符号位置，该第三时域位置为基站和终端设备协 议定义的。可以理解的是，在实际应用过程中，该系统消息还可以携带更多的信息，例如该系统信息还可以携带上行定位信息使用的带宽的信息，具体此处不做限定。
如图6所示，本实施例中，在下行信道中设计了1个下行物理信道PDCH，2个逻辑信道：广播信道BCH和下行公共控制信道DCCH。这两个逻辑信道的数据都通过相同的下行物理信道PDCH承载。其中，广播信道用于系统消息的发送，下行公共控制信道用于针对单个终端设备下发控制消息，例如资源分配消息等。
如图7所示，本实施例设计的下行物理信道由循环前缀CP，下行同步参考信号DSS(即下行同步信息)以及下行数据几部分组成。
本实施例中，将PDCH的子载波间隔设置为和NR子载波间隔相同，通过频分打孔的方式实现复用，以实现可以通过一个NR目标符号发送第二下行数据和下行同步信息。因为下行数据传输的过程中，下行数据的数据量比较大，可以采用1:3的比例进行频分打孔，如图12所示，即1个NR目标符号中，按照1份下行同步信息和3份下行数据的方式进行打孔。可以理解的是，在实际应用过程中，还可以采用其他比例进行打孔，例如1:5或者2:3的方式进行打孔，具体此处不做限定。
下行同步序列DSS，即下行同步信息，用于终端设备捕获系统消息并和基站的时间同步对齐，可选的，该DSS还可以用于信道估计。第二个符号用于发送PDCH承载的数据。
在一种可能的实现方式中，系统消息中还携带有时间信息，该时间信息用于终端设备进行时间同步。在实际应用过程中，终端设备通过基站发送的同步参考信号DSS实现与基站的频率同步，并通过时间信息实现与基站的时间同步。
PDCH使用的带宽为某个固定的带宽，例如10Mhz或者20Mhz。
DSS的调制方式采用BPSK的方式。DSS序列采用3GPP标准定义的固定m序列，或者采用低峰均比Low-PARP的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
下行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PDCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
下行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输下行数据。其中，因为下行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送广播信道，第二个固定周期发送下行控制信道。例如，广播信道在偶数帧发送，下行控制信道在奇数帧发送。下行物理信道按照10ms为一个周期，则广播信道在第一个10ms中使用该NR目标符号，下行控制信道在第二个10ms中使用该NR目标符号。如图8所示，从NR网络中切分出的目标符号为在第7个时隙中的第6个符号，则在帧0中，广播信道使用该目标符号传输系统消息，该帧0中的目标符号即为第三时域位置，在帧3中，下行控制信道使用该目标符号传输资源分配消息。
在步骤602中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的系统消息之后，终端设备根据系统消息通过上行物理信 道在第四时域位置向基站发送第二上行数据和第一上行定位信息，该第二上行数据中包括初始接入消息，该初始接入消息用于终端设备进行初始接入。
如图9所示，本实施例中，在上行信道中设计了1个上行物理信道PUCH，2个逻辑信道：接入信道ACH和上行共享信道USCH。这两个逻辑信道的数据都通过相同的上行物理信道承载。其中，接入信道用于发送初始接入消息，上行共享信道用于传输上行数据以及上行定位信息，UTDOA定位就是利用上行定位信息进行TOA的估计。
如图10所示，本实施例设计的上行物理信道由循环前缀CP，低功耗定位参考信号LPRS(即上行定位信息)以及上行数据几部分组成。
本实施例中，将PUCH的子载波间隔设置为和NR子载波间隔相同，通过频分打孔的方式实现复用，以实现可以通过一个NR目标符号发送第二上行数据和上行定位信息。因为上行数据传输的过程中，上行数据的数据量比较小，而基站需要利用上行定位信息进行TOA测量，带宽需求大，为提升定位的精度，可以采用3:1的比例进行频分打孔，如图13所示，即1个NR目标符号中，按照3份上行定位信息和1份上行数据的方式进行打孔。可以理解的是，在实际应用过程中，还可以采用其他比例进行打孔，例如3:2或者5:3的方式进行打孔，具体此处不做限定。
低功耗定位参考信号LPRS，即上行定位信息，用于基站进行TOA估计，可选的，该上行定位信息还可以用于上行物理信道的信道估计。第二个符号用于发送PUCH承载的数据。
在实际应用过程中，具体的带宽可以根据NR网络和定位系统的负荷情况进行协商配置，例如只使用其中的部分带宽传输LPRS，具体此处不做限定。
LPRS的调制方式采用BPSK的方式。LPRS序列可以采用3GPP标准定义的Low-PAPR的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
上行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PUCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
上行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输上行数据。其中，因为上行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送接入信道，第二个固定周期发送上行共享信道。例如，接入信道在偶数帧发送，上行共享信道在奇数帧发送。上行物理信道按照10ms为一个周期，则接入信道在第一个10ms中使用该NR目标符号，上行共享信道在第二个10ms中使用该NR目标符号。如图11所示，从NR网络中切分出的目标符号为在第7个时隙中的第8个符号，则在帧0中，接入信道使用该目标符号传输初始接入消息，该帧0中的目标符号即为第四时域位置，在帧0的第7个时隙中的第9个符号和帧0中的第17个时隙中的第7、8、9个符号中，上行共享信道使用这些目标符号传输定位消息。
在步骤603中，基站向终端设备发送第一下行数据。
当终端设备向基站发送初始接入消息之后，基站在第一时域位置向终端设备发送第一 下行数据，该第一下行数据包括了资源分配消息，该资源分配消息中携带了第二时域位置的信息。
可选地，基站还通过该第一时域位置发送下行同步信息，该下行同步信息用于终端设备进行时间同步。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，基站通过在该NR目标符号中发送第一下行数据和下行同步信息。具体的，可以在该NR目标符号通过频分打孔的方式发送下行同步信息和第一下行数据。
本实施例中，因为第一下行数据中包括了资源分配消息，而资源分配消息是根据终端设备的需求进行发送的。例如，当需要给终端设备分配资源时，基站才会在第一下行数据中携带资源分配消息。若终端设备不需要分配资源时，则基站可以在第一时域位置中只发送下行同步信息，不发送资源分配消息。
在步骤604中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的资源分配消息和下行同步信息之后，终端设备根据资源分配消息在第二时域位置发送第二上行数据和第一上行定位信息，该第一上行定位信息用于基站进行到达时间TOA的估计。
具体的，如前述步骤，终端设备可以在通过上行共享信道USCH在第二时域位置中发送第二上行数据和第一上行定位消息，该第二时域位置的信息是携带在基站发送的资源分配消息中的。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，终端设备通过在该NR目标符号中发送第二上行数据和第一上行定位消息。具体的，可以通过在该NR目标符号频分打孔的方式发送第一上行定位消息和第二上行数据。
在步骤605中，终端设备启动定时器，进入休眠模式。
终端设备在发送完第一上行定位消息之后，终端设备可以启动定时器，并在定时器启动之后，进入休眠模式，该休眠模式的功耗低于终端设备处于正常模式下的功耗，该定时器的时长为预设阈值。
具体的，因为终端设备没有和基站之间建立RRC连接，因此终端设备为了保持低功耗状态，可以进入休眠模式。本实施例方法中，终端设备可以通过在基站分配的指定时域资源位置接收下行同步信息和系统消息，用于终端设备与基站进行时间同步，并且接收系统消息。而在其他时间段，则可以进入休眠模式，以便于减少终端设备的功耗。
在步骤606中，当定时器超时，终端设备进入正常模式。
当定时器超时之后，终端设备退出休眠模式，进入正常模式，在正常模式下终端设备可以在基站分配的指定时域资源位置接收下行同步信息和系统消息。例如终端设备可以在第三时域位置接收基站发送的携带有系统消息的第二下行数据。
在步骤607中，终端设备向基站发送第二上行定位信息。
终端设备在进入正常模式之后，终端设备基于与基站的协议约定，在第二时域位置向基站发送第二上行定位信息，该上行定位信息用于基站进行到达时间TOA估计。
具体的，终端设备在进入正常模式之后，终端设备基于基站已经分配的时域资源信 息，向基站发送第二上行定位信息。例如，第二时域退出休眠模式，进入正常模式的时间在帧0中的第1个时隙，而基站给终端设备分配的第二时域位置是帧0中的第17个时隙中的第7个符号，则终端设备只需要等待10个时隙与7个NR目标符号的时长，就可以再次向基站发送上行定位信息。因为本实施例中限定了每1个帧中，都会有分配到至少1个NR目标符号用于发送上行定位信息，因此终端设备等待的时间较短，减少了终端设备因等待发送上行定位信息的时域资源而消耗的功耗。
在实际应用过程中，终端设备在发送完第二上行定位信息之后，又可以继续进入休眠模式，以保持低功耗的运行状态。
本申请实施例中，基站和终端设备通过更少的信息交互，就可以实现终端设备和基站之间的数据传输和定位，避免了标准UTDOA定位的复杂流程，并且可以长时间按照基站分配的时域资源周期性的发送上行定位消息，发送完成后又可以立即休眠，以保持终端设备的低功耗状态，节省了终端设备的功耗。通过频分打孔的方式发送上行数据和定位信息，不需要用到多符号进行发送，只需要通过单符号进行发送，节省了时间。
基于前述图1所示的现有技术UTDOA定位流程，本申请实施例中低功耗定位的方法与现有技术3GPP的标准UTDOA定位流程对比如下表1。

利用本申请实施例的信道除了可以简化上述R16的标准UTDOA定位流程，终端接收和发送消息的处理时间也明显少于R16标准UTDOA定位流程。本申请实施例的信道时序简单并且周期位置固定，在已经分配的符号进行接收信息和发送信息，持续时长小于1个NR目标符号。而R16标准UTDOA定位流程中，通过PDSCH接收消息时，需要先监听PDCCH信道，而PDCCH的持续时长是1-3个NR目标符号，PDSCH的时长通常是以时隙为单位的。另外，本申请实施例中的信道也无需R16标准L2的HARQ应答机制，减少了终端设备的信号发送次数。
三、通过在一个NR符号中设置两个以上的子符号的方式传输上行数据或者下行数据。
请参阅图5c，为本申请实施例提供的数据处理方法的另一流程示意图。
在步骤701中，基站向终端设备发送第二下行数据。
在低功耗定位场景中，基站会先通过第三时域位置在下行物理信道PDCH发送第二下行数据，该第二下行数据包括系统消息，该系统消息中携带第四时域位置的信息，该第四时域的位置信息用于指示初始接入信道的符号位置，该第三时域位置为基站和终端设备协议定义的。可以理解的是，在实际应用过程中，该系统消息还可以携带更多的信息，例如该系统信息还可以携带上行定位信息使用的带宽的信息，具体此处不做限定。
如图6所示，本实施例中，在下行信道中设计了1个下行物理信道PDCH，2个逻辑信道：广播信道BCH和下行公共控制信道DCCH。这两个逻辑信道的数据都通过相同的下行物理信道PDCH承载。其中，广播信道用于系统消息的发送，下行公共控制信道用于针对单个终端设备下发控制消息，例如资源分配消息等。
如图14所示，本实施例设计的下行物理信道由循环前缀CP，下行同步参考信号DSS(即下行同步信息)以及下行数据几部分组成。
在一种可能的实现方式中，系统消息中还携带有时间信息，该时间信息用于终端设备进行时间同步。在实际应用过程中，终端设备通过基站发送的同步参考信号DSS实现与基站的频率同步，并通过时间信息实现与基站的时间同步。
本实施例中，下行物理信道的子载波间隔为新空口NR子载波间隔的N倍，N为大于2的正整数。其中，第一时域位置包括N个第一子符号，终端设备在M个第一字符号接收下行同步信息，终端设备在(N-M)个第一子符号接收第二下行数据。第三时域位置也包括了N个第二子符号，终端设备在M个第二子符号接收下行同步信息，终端设备在(N-M)个第二子符号接收第二下行数据，且，N个第一子符号的时长之和等于目标符号的时长，N个第二子符号的时长之和也等于目标符号的时长，其中，M为大于或者等于1的正整数，(N-M)为大于或者等于1的正整数。
举例来说，将PDCH的子载波间隔设置为NR子载波间隔的3倍或者3倍以上，使得本实施例中所使用的子符号的时长为NR符号时长的三分之一以下，因此，当从NR网络中切分一个目标符号使用时，本实施例可以使用三个以上的子符号来承载数据。例如，NR使用30K子载波间隔，则PDCH采用90K子载波间隔或者120K子载波间隔，则子符号的时长为NR符号时长的三分之一或者四分之一，即可以将一个目标符号作为三个以上的子符号进行使用。
其中，PDCH采用多符号设计，每个符号都带有循环前缀CP。第一个符号发送下行同步序列DSS，即下行同步信息，用于终端设备捕获系统消息并和基站的时间同步对齐，可选的，该DSS还可以用于信道估计。其余的符号可以用于发送PDCH承载的数据。
PDCH使用的带宽为某个固定的带宽，例如10Mhz或者20Mhz。
DSS的调制方式采用BPSK的方式。DSS序列采用3GPP标准定义的固定m序列，或者采用低峰均比Low-PARP的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
下行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PDCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
下行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输下行数据。其中，因为下行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送广播信道，第二个固定周期发送下行控制信道。例如，广播信道在偶数帧发送，下行控制信道在奇数帧发送。下行物理信道按照10ms为一个周期，则广播信道在第一个10ms中使用该NR目标符号，下行控制信道在第二个10ms中使用该NR目标符号。如图8所示，从NR网络中切分出的目标符号为在第7个时隙中的第6个符号，则在帧0中，广播信道使用该目标符号传输系统消息，该帧0中的目标符号即为第三时域位置，在帧3中，下行控制信道使用该目标符号传输资源分配消息。
在步骤702中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的系统消息之后，终端设备根据系统消息通过上行物理信道在第四时域位置向基站发送第二上行数据和第一上行定位信息，该第二上行数据中包括初始接入消息，该初始接入消息用于终端设备进行初始接入。
如图9所示，本实施例中，在上行信道中设计了1个上行物理信道PUCH，2个逻辑信道：接入信道ACH和上行共享信道USCH。这两个逻辑信道的数据都通过相同的上行物理信道承载。其中，接入信道用于发送初始接入消息，上行共享信道用于传输上行数据以及上行定位信息，UTDOA定位就是利用上行定位信息进行TOA的估计。
如图15所示，本实施例设计的上行物理信道由循环前缀CP，低功耗定位参考信号LPRS(即上行定位信息)以及上行数据几部分组成。
本实施例中，上行物理信道的子载波间隔为新空口NR子载波间隔的N倍，N为大于2的正整数。其中，第二时域位置包括N个第三子符号，终端设备在M个第三子符号发送上 行定位信息，终端设备在(N-M)个第三子符号发送第一上行数据。第四时域位置也包括了N个第四子符号，终端设备在M个第四字符号发送上行定位信息，终端设备在(N-M)个第四子符号发送第二上行数据，N个第三子符号的时长之和等于目标符号的时长，N个第四子符号的时长之和等于目标符号的时长，目标符号为NR的符号，M为大于或者等于1的正整数，(N-M)为大于或者等于1的正整数。
举例来说，将PUCH的子载波间隔设置为NR子载波间隔的3倍或者3倍以上，使得本实施例中所使用的子符号的时长为NR符号时长的三分之一以下，因此，当从NR网络中切分一个目标符号使用时，本实施例可以使用三个以上的子符号来承载数据。例如，NR使用30K子载波间隔，则PDCH采用90K子载波间隔或者120K子载波间隔，则子符号的时长为NR符号时长的三分之一或者四分之一，即可以将一个目标符号作为三个以上的子符号进行使用。
其中，PUCH采用多符号设计，每个符号都带有循环前缀CP。低功耗定位参考信号LPRS，即上行定位信息，用于基站进行TOA估计，可选的，该上行定位信息还可以用于上行物理信道的信道估计。其余的符号可以用于发送PUCH承载的数据或者上行定位信息，具体此处不做限定。
与PDCH的带宽使用情况不同，PUCH占用的带宽分成两部分。当通过发送LPRS时，通常是使用全带宽。发送LPRS时使用全带宽是由于UTDOA定位的精度要求，使用更多的带宽发送更多的LPRS，可以更准确的进行UTDOA定位，进而可以提高UTODA的定位精准度。在实际应用过程中，具体的带宽可以根据NR网络和定位系统的负荷情况进行协商配置，例如只使用其中的部分带宽传输LPRS，具体此处不做限定。
而通过发送上行数据时，可以使用某个固定的带宽，例如10Mhz或者20Mhz，因为在定位场景下，需要发送的上行数据较少，因此可以不占用全带宽，节省带宽资源。在实际应用过程中，发送上行数据时，也可以使用全带宽，具体此处不做限定。
LPRS的调制方式采用BPSK的方式。LPRS序列可以采用3GPP标准定义的Low-PAPR的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
上行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PUCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
上行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输上行数据。其中，因为上行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送接入信道，第二个固定周期发送上行共享信道。例如，接入信道在偶数帧发送，上行共享信道在奇数帧发送。上行物理信道按照10ms为一个周期，则接入信道在第一个10ms中使用该NR目标符号，上行共享信道在第二个10ms中使用该NR目标符号。如图11所示，从NR网络中切分出的目标符号为在第7个时隙中的第8个符号，则在帧0中，接入信道使用该目标符号传输初始接入消息，该帧0中的目标符号即为第四时域位置，在帧0的第7个时隙中的第9个符号和帧0中的第17个时隙中的第7、8、9个符号中，上行 共享信道使用这些目标符号传输定位消息。
在步骤703中，基站向终端设备发送第一下行数据。
当终端设备向基站发送初始接入消息之后，基站在第一时域位置向终端设备发送第一下行数据，该第一下行数据包括了资源分配消息，该资源分配消息中携带了第二时域位置的信息。
可选地，基站还通过该第一时域位置发送下行同步信息，该下行同步信息用于终端设备进行时间同步。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，基站通过在该NR目标符号中发送第一下行数据和下行同步信息。具体的，可以在该NR目标符号的第一子符号中发送下行同步信息，在其余子符号中发送第一下行数据。
本实施例中，因为第一下行数据中包括了资源分配消息，而资源分配消息是根据终端设备的需求进行发送的。例如，当需要给终端设备分配资源时，基站才会在第一下行数据中携带资源分配消息。若终端设备不需要分配资源时，则基站可以在第一时域位置中只发送下行同步信息，不发送资源分配消息。
在步骤704中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的资源分配消息和下行同步信息之后，终端设备根据资源分配消息在第二时域位置发送第二上行数据和第一上行定位信息，该第一上行定位信息用于基站进行到达时间TOA的估计。
具体的，如前述步骤，终端设备可以在通过上行共享信道USCH在第二时域位置中发送第二上行数据和第一上行定位消息，该第二时域位置的信息是携带在基站发送的资源分配消息中的。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，终端设备通过在该NR目标符号中发送第二上行数据和第一上行定位消息。具体的，可以在该NR目标符号的第一子符号中发送第一上行定位消息，在其余的子符号中发送第二上行数据或者第一上行定位消息，具体此处不做限定。
在实际应用过程中，终端设备发送上行数据的数据量会小一些，且在定位场景下，基站对定位的精准度要求较高。因此，终端设备可以在发送第一上行定位消息时，使用最大带宽，以确保发送更多的第一上行定位消息。而在发送第二上行数据时，可以根据实际的数据量进行调整，若数据量小，则使用较少的带宽发送第二上行数据，可以节省带宽资源。
在步骤705中，终端设备启动定时器，进入休眠模式。
终端设备在发送完第一上行定位消息之后，终端设备可以启动定时器，并在定时器启动之后，进入休眠模式，该休眠模式的功耗低于终端设备处于正常模式下的功耗，该定时器的时长为预设阈值。
具体的，因为终端设备没有和基站之间建立RRC连接，因此终端设备为了保持低功耗状态，可以进入休眠模式。本实施例方法中，终端设备可以通过在基站分配的指定时域资源位置接收下行同步信息和系统消息，用于终端设备与基站进行时间同步，并且接收系统 消息。而在其他时间段，则可以进入休眠模式，以便于减少终端设备的功耗。
在步骤706中，当定时器超时，终端设备进入正常模式。
当定时器超时之后，终端设备退出休眠模式，进入正常模式，在正常模式下终端设备可以在基站分配的指定时域资源位置接收下行同步信息和系统消息。例如终端设备可以在第三时域位置接收基站发送的携带有系统消息的第二下行数据。
在步骤707中，终端设备向基站发送第二上行定位信息。
终端设备在进入正常模式之后，终端设备基于与基站的协议约定，在第二时域位置向基站发送第二上行定位信息，该上行定位信息用于基站进行到达时间TOA估计。
具体的，终端设备在进入正常模式之后，终端设备基于基站已经分配的时域资源信息，向基站发送第二上行定位信息。例如，第二时域退出休眠模式，进入正常模式的时间在帧0中的第1个时隙，而基站给终端设备分配的第二时域位置是帧0中的第17个时隙中的第7个符号，则终端设备只需要等待10个时隙与7个NR目标符号的时长，就可以再次向基站发送上行定位信息。因为本实施例中限定了每1个帧中，都会有分配到至少1个NR目标符号用于发送上行定位信息，因此终端设备等待的时间较短，减少了终端设备因等待发送上行定位信息的时域资源而消耗的功耗。
在实际应用过程中，终端设备在发送完第二上行定位信息之后，又可以继续进入休眠模式，以保持低功耗的运行状态。
本申请实施例中，基站和终端设备通过更少的信息交互，就可以实现终端设备和基站之间的数据传输和定位，避免了标准UTDOA定位的复杂流程，并且可以长时间按照基站分配的时域资源周期性的发送上行定位消息，发送完成后又可以立即休眠，以保持终端设备的低功耗状态，节省了终端设备的功耗。通过多符号的方式发送上行数据和定位信息，提升了发送上行数据和上行定位信息的数据量。
基于前述图1所示的现有技术UTDOA定位流程，本申请实施例中低功耗定位的方法与现有技术3GPP的标准UTDOA定位流程对比如下表1。

利用本申请实施例的信道除了可以简化上述R16的标准UTDOA定位流程，终端接收和发送消息的处理时间也明显少于R16标准UTDOA定位流程。本申请实施例的信道时序简单并且周期位置固定，在已经分配的符号进行接收信息和发送信息，持续时长小于1个NR目标符号。而R16标准UTDOA定位流程中，通过PDSCH接收消息时，需要先监听PDCCH信道，而PDCCH的持续时长是1-3个NR目标符号，PDSCH的时长通常是以时隙为单位的。另外，本申请实施例中的信道也无需R16标准L2的HARQ应答机制，减少了终端设备的信号发送次数。
四、通过频分复用和在一个NR符号中设置两个或者两个以上符号的方式在一个NR符号中传输上行数据或者下行数据。
请参阅图5d，为本申请实施例提供的数据处理方法的另一流程示意图。
在步骤801中，基站向终端设备发送第二下行数据。
在低功耗定位场景中，基站会先通过第三时域位置在下行物理信道PDCH发送第二下行数据，该第二下行数据包括系统消息，该系统消息中携带第四时域位置的信息，该第四时域的位置信息用于指示初始接入信道的符号位置，该第三时域位置为基站和终端设备协议定义的。可以理解的是，在实际应用过程中，该系统消息还可以携带更多的信息，例如该系统信息还可以携带上行定位信息使用的带宽的信息，具体此处不做限定。
如图6所示，本实施例中，在下行信道中设计了1个下行物理信道PDCH，2个逻辑信道：广播信道BCH和下行公共控制信道DCCH。这两个逻辑信道的数据都通过相同的下行物理信道PDCH承载。其中，广播信道用于系统消息的发送，下行公共控制信道用于针对单个终端设备下发控制消息，例如资源分配消息等。
如图14所示，本实施例设计的下行物理信道由循环前缀CP，下行同步参考信号DSS(即下行同步信息)以及下行数据几部分组成。
在一种可能的实现方式中，系统消息中还携带有时间信息，该时间信息用于终端设备进行时间同步。在实际应用过程中，终端设备通过基站发送的同步参考信号DSS实现与基站的频率同步，并通过时间信息实现与基站的时间同步。
本实施例中，下行物理信道的子载波间隔为新空口NR子载波间隔的N倍，N为大于或 者等于2的正整数。其中，第一时域位置包括N个第一子符号，终端设备在M个第一字符号接收下行同步信息，终端设备在(N-M)个第一子符号接收第二下行数据。第三时域位置也包括了N个第二子符号，终端设备在M个第二子符号接收下行同步信息，终端设备在(N-M)个第二子符号接收第二下行数据，且，N个第一子符号的时长之和等于目标符号的时长，N个第二子符号的时长之和也等于目标符号的时长，其中，M为大于或者等于1的正整数，(N-M)为大于或者等于1的正整数。
举例来说，将PDCH的子载波间隔设置为NR子载波间隔的2倍或者2倍以上，使得本实施例中所使用的子符号的时长为NR符号时长的二分之一以下，因此，当从NR网络中切分一个目标符号使用时，本实施例可以使用两个以上的子符号来承载数据。例如，NR使用30K子载波间隔，则PDCH采用60K子载波间隔或者120K子载波间隔，则子符号的时长为NR符号时长的二分之一或者四分之一，即可以将一个目标符号作为两个以上的子符号进行使用。并且，还可以在子符号中通过频分打孔的方式实现复用，以实现可以通过一个子符号发送第二下行数据和下行同步信息。因为下行数据传输的过程中，下行数据的数据量比较大，可以采用1:3的比例进行频分打孔，即1个NR目标符号中，按照1份下行同步信息和3份下行数据的方式进行打孔，并且在4个符号中都进行打孔。可以理解的是，在实际应用过程中，还可以采用其他比例进行打孔，例如1:5或者2:3的方式进行打孔，具体此处不做限定。
本实施例中，可以通过几种方式进行打孔，一种是仅第一个子符号携带下行同步信息，其余子符号都是数据。例如图16所示，在第一子符号中，按照1份下行同步信息和3份下行数据的方式进行打孔，并且在4个符号中都进行打孔。
还可以是所有符号都携带上行定位信息。如图18所示，在所有子符号中，都是按照1份下行同步信息和3份下行数据的方式进行打孔。
其中，PDCH采用多符号设计，每个符号都带有循环前缀CP。第一个符号发送下行同步序列DSS，即下行同步信息，用于终端设备捕获系统消息并和基站的时间同步对齐，可选的，该DSS还可以用于信道估计。其余的符号可以用于发送PDCH承载的数据。
PDCH使用的带宽为某个固定的带宽，例如10Mhz或者20Mhz。
DSS的调制方式采用BPSK的方式。DSS序列采用3GPP标准定义的固定m序列，或者采用低峰均比Low-PARP的固定ZC序列，可以理解的是，还可以采用其他类型的序列，具体此处不做限定。
下行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PDCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。

在步骤802中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的系统消息之后，终端设备根据系统消息通过上行物理信道在第四时域位置向基站发送第二上行数据和第一上行定位信息，该第二上行数据中包括初始接入消息，该初始接入消息用于终端设备进行初始接入。
如图9所示，本实施例中，在上行信道中设计了1个上行物理信道PUCH，2个逻辑信道：接入信道ACH和上行共享信道USCH。这两个逻辑信道的数据都通过相同的上行物理信道承载。其中，接入信道用于发送初始接入消息，上行共享信道用于传输上行数据以及上行定位信息，UTDOA定位就是利用上行定位信息进行TOA的估计。
如图15所示，本实施例设计的上行物理信道由循环前缀CP，低功耗定位参考信号LPRS(即上行定位信息)以及上行数据几部分组成。
本实施例中，上行物理信道的子载波间隔为新空口NR子载波间隔的N倍，N为大于或者等于2的正整数。其中，第二时域位置包括N个第三子符号，终端设备在M个第三子符号发送上行定位信息，终端设备在(N-M)个第三子符号发送第一上行数据。第四时域位置也包括了N个第四子符号，终端设备在M个第四字符号发送上行定位信息，终端设备在(N-M)个第四子符号发送第二上行数据，N个第三子符号的时长之和等于目标符号的时长，N个第四子符号的时长之和等于目标符号的时长，目标符号为NR的符号，M为大于或者等于1的正整数，(N-M)为大于或者等于1的正整数。

本实施例中，可以通过几种方式进行打孔，一种是仅第一个子符号携带上行数据，其余子符号都是上行定位信息。例如图17所示，在第一子符号中，按照3份上行定位信息和1份上行数据的方式进行打孔，并且在4个符号中都进行打孔。
还可以是所有符号都携带上行定位信息。如图19所示，在所有子符号中，都是按照3份下行同步信息和1份下行数据的方式进行打孔。
其中，PUCH采用多符号设计，每个符号都带有循环前缀CP。低功耗定位参考信号LPRS，即上行定位信息，用于基站进行TOA估计，可选的，该上行定位信息还可以用于上行物理信道的信道估计。其余的符号可以用于发送PUCH承载的数据或者上行定位信息，具体此处不做限定。

上行数据可以采用QPSK、16QAM或者64QAM等3GPP标准采用的调制方式，具体此处不做限定。
PUCH的信道编码可以采用卷积码，Polar码，LDPC码等3GPP常用编码方式，具体此处不做限定。
上行物理信道按照固定的周期，从NR网络中划分一个NR目标符号用于传输上行数据。其中，因为上行物理信道设计了两个逻辑信道，这两个逻辑信道交替发送，即第一个固定周期发送接入信道，第二个固定周期发送上行共享信道。例如，接入信道在偶数帧发送，上行共享信道在奇数帧发送。上行物理信道按照10ms为一个周期，则接入信道在第一个10ms中使用该NR目标符号，上行共享信道在第二个10ms中使用该NR目标符号。如图11所示，从NR网络中切分出的目标符号为在第7个时隙中的第8个符号，则在帧0中，接入信道使用该目标符号传输初始接入消息，该帧0中的目标符号即为第四时域位置，在帧0的第7个时隙中的第9个符号和帧0中的第17个时隙中的第7、8、9个符号中，上行共享信道使用这些目标符号传输定位消息。
在步骤803中，基站向终端设备发送第一下行数据。
当终端设备向基站发送初始接入消息之后，基站在第一时域位置向终端设备发送第一下行数据，该第一下行数据包括了资源分配消息，该资源分配消息中携带了第二时域位置的信息。
可选地，基站还通过该第一时域位置发送下行同步信息，该下行同步信息用于终端设备进行时间同步。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，基站通过在该NR目标符号中发送第一下行数据和下行同步信息。具体的，可以在该NR目标符号的第一子符号中发送下行同步信息，在其余子符号中发送第一下行数据。
本实施例中，因为第一下行数据中包括了资源分配消息，而资源分配消息是根据终端 设备的需求进行发送的。例如，当需要给终端设备分配资源时，基站才会在第一下行数据中携带资源分配消息。若终端设备不需要分配资源时，则基站可以在第一时域位置中只发送下行同步信息，不发送资源分配消息。
在步骤804中，终端设备向基站发送第二上行数据和第一上行定位信息。
终端设备在接收到基站发送的资源分配消息和下行同步信息之后，终端设备根据资源分配消息在第二时域位置发送第二上行数据和第一上行定位信息，该第一上行定位信息用于基站进行到达时间TOA的估计。
具体的，如前述步骤，终端设备可以在通过上行共享信道USCH在第二时域位置中发送第二上行数据和第一上行定位消息，该第二时域位置的信息是携带在基站发送的资源分配消息中的。
如前述步骤，该第一时域位置为通过NR网络切分到的时域资源，即为一个NR目标符号，终端设备通过在该NR目标符号中发送第二上行数据和第一上行定位消息。具体的，可以在该NR目标符号中的多个子符号中的任一子符号中发送第一上行定位信息和第二上行数据，或者只在第一子符号中发送第一上行定位信息和上行数据，在其他符号发送上行数据，具体此处不做限定。
在实际应用过程中，终端设备发送上行数据的数据量会小一些，且在定位场景下，基站对定位的精准度要求较高。因此，终端设备可以在发送第一上行定位消息时，使用最大带宽，以确保发送更多的第一上行定位消息。而在发送第二上行数据时，可以根据实际的数据量进行调整，若数据量小，则使用较少的带宽发送第二上行数据，可以节省带宽资源。
在步骤805中，终端设备启动定时器，进入休眠模式。
终端设备在发送完第一上行定位消息之后，终端设备可以启动定时器，并在定时器启动之后，进入休眠模式，该休眠模式的功耗低于终端设备处于正常模式下的功耗，该定时器的时长为预设阈值。
具体的，因为终端设备没有和基站之间建立RRC连接，因此终端设备为了保持低功耗状态，可以进入休眠模式。本实施例方法中，终端设备可以通过在基站分配的指定时域资源位置接收下行同步信息和系统消息，用于终端设备与基站进行时间同步，并且接收系统消息。而在其他时间段，则可以进入休眠模式，以便于减少终端设备的功耗。
在步骤806中，当定时器超时，终端设备进入正常模式。
当定时器超时之后，终端设备退出休眠模式，进入正常模式，在正常模式下终端设备可以在基站分配的指定时域资源位置接收下行同步信息和系统消息。例如终端设备可以在第三时域位置接收基站发送的携带有系统消息的第二下行数据。
在步骤807中，终端设备向基站发送第二上行定位信息。
终端设备在进入正常模式之后，终端设备基于与基站的协议约定，在第二时域位置向基站发送第二上行定位信息，该上行定位信息用于基站进行到达时间TOA估计。
具体的，终端设备在进入正常模式之后，终端设备基于基站已经分配的时域资源信息，向基站发送第二上行定位信息。例如，第二时域退出休眠模式，进入正常模式的时间 在帧0中的第1个时隙，而基站给终端设备分配的第二时域位置是帧0中的第17个时隙中的第7个符号，则终端设备只需要等待10个时隙与7个NR目标符号的时长，就可以再次向基站发送上行定位信息。因为本实施例中限定了每1个帧中，都会有分配到至少1个NR目标符号用于发送上行定位信息，因此终端设备等待的时间较短，减少了终端设备因等待发送上行定位信息的时域资源而消耗的功耗。
在实际应用过程中，终端设备在发送完第二上行定位信息之后，又可以继续进入休眠模式，以保持低功耗的运行状态。
本申请实施例中，基站和终端设备通过更少的信息交互，就可以实现终端设备和基站之间的数据传输和定位，避免了标准UTDOA定位的复杂流程，并且可以长时间按照基站分配的时域资源周期性的发送上行定位消息，发送完成后又可以立即休眠，以保持终端设备的低功耗状态，节省了终端设备的功耗。通过多符号的方式发送上行数据和定位信息，提升了发送上行数据和上行定位信息的数据量。通过频分打孔的方式发送上行数据和定位信息，且用多符号进行发送，并且在单位时间内可以发送更多的数据量。且对上行定位信息和上行数据的传输方式控制更加灵活。
基于前述图1所示的现有技术UTDOA定位流程，本申请实施例中低功耗定位的方法与现有技术3GPP的标准UTDOA定位流程对比如下表1。

利用本申请实施例的信道除了可以简化上述R16的标准UTDOA定位流程，终端接收和发送消息的处理时间也明显少于R16标准UTDOA定位流程。本申请实施例的信道时序简单并且周期位置固定，在已经分配的符号进行接收信息和发送信息，持续时长小于1个NR目标符号。而R16标准UTDOA定位流程中，通过PDSCH接收消息时，需要先监听PDCCH信道，而PDCCH的持续时长是1-3个NR目标符号，PDSCH的时长通常是以时隙为单位的。另外，本申请实施例中的信道也无需R16标准L2的HARQ应答机制，减少了终端设备的信号发送次数。
