Description

信息收发方法和设备
本申请要求于2017年03月23日提交中国专利局、申请号为201710179820.5、申请名称为“信息收发方法和设备”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
本申请涉及通信技术，尤其涉及一种信息收发方法和设备。
背景技术
随着通信技术的不断发展，第五代移动通信技术(5th-Generation，5G)已经开始研究及标准化工作。从5G的兼容性来考虑，5G的兼容性分为两条分值，一条为兼容长期演进(Long Term Evolution，LTE)4G的持续演进，另一条为不兼容LTE的新无线(New Radio，NR)系统。其中的NR系统一般会部署在高频点，比如3.5GHz甚至28GHz等。因此，网络设备可以在NR高频下行载波上发送下行信号，且网络设备需要采用大规模天线阵列来实现高增益的波束赋形，来增强下行信号的覆盖，然后在该网络设备所管辖范围的终端设备可以接收到该下行信号。然而，终端设备一般来说由于尺寸限制很可能不会使用过多的天线个数去实现波束赋形，从而终端设备在NR高频上行载波上向网络设备发送上行信号的时候，该上行信号的信号覆盖较小，造成系统上下行覆盖不一致问题，最终导致系统的部署只能以上行覆盖为准，即上行覆盖为系统的瓶颈。
针对上述NR系统的上行覆盖受限的问题，目前标准上采用NR与LTE共存的方式来解决。图1为现有技术中NR与LTE共存的部署场景图，如图1所示，终端设备在NR高频下行载波上接收网络设备发送的下行信号，并且，终端设备在LTE低频上行载波上向网络设备发送上行信号，从而解决终端设备发送的上行信号的信号质量较差的问题。
然而上述现有技术中，终端设备在NR高频下行载波上接收网络设备发送的下行信号的时候，终端设备会根据该NR高频下行载波所对应的配置信息对该NR高频下行载波的参考信号等进行测量，以获取下行的参考信息，参考信息例如有下行的路径损耗、下行接收定时、下行时频同步信息等等；从而，就可以将获取到的下行的参考信息用于终端设备在LTE低频上行载波上向网络设备发送上行信号时参考量的确定，参考量例如有上行发送功率、上行发送定时等等。然而由于LTE与NR的频点相差加大，采用NR高频下行载波所对应的配置信息来获取到的下行的参考信息，去进行LTE低频上行载波上信号的发送的时候，该下行的参考信息不能准确的表达出上行载波上的信号的特征，进而会导致该NR与LTE共存场景下的系统的性能下降。

2)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，其包括各种通信制式中的网络设备，例如包括但不限于：基站、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、网络设备控制器(Base Station Controller，BSC)、网络设备收发台(Base Transceiver Station,BTS)、家庭网络设备(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)等。
3)网络设备，包括了各类频率制式的网络设备，例如包括但不限于：低频网络设备、高频网络设备。
4)“多个”是指两个或两个以上，其它量词与之类似。“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。字符“/”一般表示前后关联对象是一种“或”的关系。
图2为本申请实施例提供的一种应用场景示意图。如图2所示的组网架构，主要包括网络设备和终端设备。网络设备可以使用相对较高的频率的毫米波频段与终端设备通信，毫米波频段通常为大于3.5GHz以上的频段，例如，3.5GHz，28GHz，38GHz；并且，网络设备也可以使用相对较低的频率的频段与终端设备通信，低频频段通常为小于3.5GHz的频段，例如1.5GHz，800M。进而网络设备是支持多个频段的，是支持高频、低频的。
本申请实施中的网络设备可以是工作在3.5GHz以下频段、且支持3.5GHz(包括3.5GHz)以上频段的网络侧设备，例如，无线保真(Wireless-Fidelity，Wi-Fi)的接入点、下一代通信的基站，如5G的gNB或小站、微站，TRP，还可以是工作在高频频段的中继站、接入点、车载设备、可穿戴设备等。
其中，本申请实施例中的终端设备可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。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网络中的终端等。本申请实施例中的终端设备可以为支持NR的终端，也可以为支持未来版本LTE的终端，例如支持LTE版本15及以后版本的终端。
在介绍本申请的具体实施方式之前，首先介绍一下LTE系统，基于提高设备的功率效率、延长电池的续航时间、以及设备成本上的考虑，LTE系统下行基于OFDMA进行实现，LTE系统上行基于单载波频分多址(Single Carrier Frequency Division Multiple Access，SC-FDMA)进行实现。时频资源被划分成时间域维度上的时域符号和频率域维度上的子载波，其中，时域符号为OFDM或SC-FDMA符号。最小的资源粒度叫做一个RE(Resouce Element，RE)，表示时间域上的一个时域符号和频率域上的一个子载波组成的时频格点。LTE系统进行调度的基本时间单位一般是一个子帧，时长为1ms；其中，一个子帧一般包括两个时隙，一个时隙一般包括7个时域符号。一个时隙内所有的时域符号与频域上12个子载波组成的一个资源块，叫做RB(Resource Block，RB)，LTE资源调度就是以RB 为基本单位的，具体来说，LTE系统中调度的基本频率单位为资源块RB的频域宽度，一个RB频域上包括12个子载波，时域上占用一个子帧的时长。LTE演进系统中还会考虑引入更短的时间调度单位，比如以一个时隙甚至几个时域符号为单位的调度方式。LTE支持频分双工(Frequency Division Duplexing，FDD)和时分双工(Time Division Duplexing，TDD)两种双工方式。对于FDD来说，下行和上行在不同的载波上传输；对于TDD来说，上行和下行在同一载波的不同时间来传输；在一个载波上包括下行子帧，上行子帧和特殊子帧，其中，特殊子帧中包括DwPTS，GP和UpPTS三个部分。其中的GP主要用于下行到上行的器件转换时间和传播时延的补偿。LTE系统当前主要部署在低频段，比如800MHz至2GHz左右。
再介绍一下5G技术，5G技术需要支持高达10G的下行速率，5G技术使用的频谱范围非常广，例如从低于6GHz的频段到100GHz的频段，从而高频技术是5G必然要考虑的问题。在高频信号的传输中，高频信号易受到传输条件的影响，进而导致高频信号的质量会很差，为了增强高频信号，一般采用波束赋形(beam forming)技术通过增益天线去提升高频信号传输的性能。

其中，第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第一下行载波与第二上行载波属于终端设备的服务载波，且第二下行载波不属于终端设备的服务载波；第二下行载波与第二上行载波为系统级成对的载波。广播消息中还包括与第二上行载波对应的第二上行配置信息；其中，第二上行配置信息中包括第二上行载波的第二上行频点信息。并且，第一下行载波位于第一频段，第二上行载波和第二下行载波位于第二频段，其中，第一频段的频率大于第二频段的频率。
在本实施例中，在现有技术中，在如图1所示的场景下，终端设备采用NR下行载波与LTE上行载波作为服务载波，现有技术中，与该NR下行载波对应的上行载波就是该LTE上行载波，而NR下行载波、LTE上行载波的频率是相差较大的。举例来说，网络设备在 NR上行(Uplink，UL)/TDD载波上发送下行信号，位于网络设备所管辖范围内的终端设备根据自身需求接收该下行信号；终端设备在FDD下行(Downlink，DL)载波上向网络设备发送上行信号。此时，终端设备没有配置LTE下行载波为其服务载波。从而，终端设备在LTE上行载波上向网络设备发送上行信号的时候，发送上行信号所需要的参考信息是依据NR下行载波而计算得到的。
其中，在本申请的方案中，终端设备接入到网络设备后，终端设备与网络设备建立了无线资源控制(Radio Resource Control，RRC)连接之后，为该终端设备与该网络设备之间的通信承载上行信号或下行信号的载波，称为该终端设备的服务载波。举例来说，终端设备与网络设备建立起了RRC连接之后，终端设备在A上行载波上向网络设备发送A上行信号，此时，A上行载波为终端设备的服务载波；再举例来说，终端设备与网络设备建立起了RRC连接之后，终端设备在B下行载波上接收网络设备发送的B下行信号，此时，B下行载波为终端设备的服务载波；再举例来说，终端设备与网络设备建立起了RRC连接之后，终端设备在C下行载波上接收网络设备发送的C下行信号，终端设备进行的处理之后，终端设备在D上行载波上向网络设备发送D上行信号，此时，C下行载波、D上行载波都是终端设备的服务载波，且可以称C下行载波与D上行载波是终端设备的一对服务载波。在本申请的方案中，终端设备与网络设备建立起了RRC连接之后，终端设备在第一下行载波上接收网络设备发送的广播消息，从而第一下行载波属于终端设备的服务载波；在后续的过程中，终端设备会在第二上行载波上向网络设备发送上行信号，从而第二上行载波属于终端设备的服务载波；然而，终端设备不会在第二下行载波上接收网络设备发送的下行信号，从而第二下行载波不属于终端设备的服务载波。
在本申请的方案中，网络设备和终端设备支持的第一下行载波为NR DL载波，举例来说，第一下行载波可以为NR纯DL载波、或为NR TDD中的DL载波、或者为NR FDD中的DL载波；第一下行载波可以部署在第一频段，可以选用频率大于等于2.5GHz的频段，举例来说，第一下行载波的频率为20GHz至30GHz，或者第一下行载波的频率为3.5GHz。
相应的，该第一下行载波所对应的上行载波为第二上行载波，网络设备和终端设备支持的该第二上行载波为LTE UL载波，该第二上行载波位于第二频段，第一频段的频率大于第二频段的频率；可以将第二上行载波部署在低频段，举例来说，第二上行载波为800MHz或2GHz频段的LTE FDD UL、或者为800MHz或2GHz频段的TDD UL载波。
由于对于作为下行载波的第一下行载波来说，与其对应的上行载波为第二上行载波，可知，第一下行载波与第二上行载波属于当前的终端设备的服务载波。
终端设备接收网络设备在第一下行载波上发送的广播消息的过程如下。如图4所示，在网络设备在第一下行载波上，向当前的终端设备发送一个广播消息，在该广播消息中会承载第一下行载波的小区级别信息，例如，第一下行载波上的DL带宽信息和/或载波基本结构信息；该广播消息中还会承载与第二下行载波对应的第二下行配置信息、以及与第二上行载波对应的第二上行配置信息；第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第二上行配置信息中包括第二上行载波的第二上行频点信息。终端设备接收到广播消息之后，终端设备可以根据第二下行频点信息确定第二下行载波的具体频域位置；物理小区标识信息可以指示该第二上行载波所对应的网络设备侧的第二下行载波是该终端设备附近的哪个网络设备或哪个LTE小区所管辖，进而在本申请中， 终端设备就不需要进行其他LTE小区的小区标识的搜索，并且依据该物理小区标识信息，终端设备可以准确的确定出管辖该第二下行载波的LTE小区。
在本申请中，第二下行载波不属于当前的终端设备的服务载波，网络设备不通过该第二下行载波向当前的终端设备发送下行信号。并且，该第二下行载波位于第二频段，可以将第二下行载波部署在低频段，举例来说，第二下行载波为800MHz或2GHz频段的LTE FDD UL、或者为800MHz或2GHz频段的TDD UL载波。在本申请中，可以将第二上行载波和第二下行载波部署在第二频段的同一频率上。
在本申请中，第二下行载波与第二上行载波是系统级成对的载波。
首先，系统级成对的载波的定义为：一对下行载波和一个上行载波，在网络设备所管辖范围下的第一终端设备从该下行载波进行下行接入，并且该第一终端设备从该下行载波上读取该上行载波上随机接入配置信息，进而该某一个终端设备根据该随机接入配置信息在该上行载波上发起随机接入，最终该某一个终端设备完成RRC连接建立；能够完全上述功能的该上行载波和该下行载波可以称为系统级成对载波。举例来说，在网络设备所管辖范围下的某一个终端设备M从E下行载波进行下行接入，并且该终端设备M从E下行载波上读取F上行载波上随机接入配置信息，进而终端设备M根据该随机接入配置信息在F上行载波上发起随机接入，终端设备M完成RRC连接建立，此时，E下行载波与F上行载波为系统级成对载波。
本申请的方案中涉及两套系统级成对载波：其中的一套系统级成对载波是指第一下行载波和第二上行载波，具体的，一个支持NR的终端设备从第一下行载波接入，并从该第一下行载波上读取该第二上行载波上的随机接入配置信息，进而该支持NR的终端设备根据该随机接入配置信息在该第二上行载波上发起随机接入，最终该支持NR的终端设备完成RRC连接建立，在这里，第一下行载波与第二上行载波为系统级成对的载波；另一套系统级成对载波是指第二下行载波和第二上行载波，具体的，一个支持LTE的终端设备从第二下行载波接入，并从该第二下行载波上读取该第二上行载波上的随机接入配置信息，进而支持LTE的终端设备根据该随机接入配置信息在该第二上行载波上发起随机接入，最终该支持LTE的终端设备完成RRC连接建立，在这里，第二下行载波与第二上行载波为系统级成对的载波。
在本申请中，第二上行载波为当前的终端设备的服务载波，第二下行载波不是该终端设备的服务载波，但是，会将第二下行载波的第二下行配置信息放入到第一上行载波的广播信息中，使得在第二上行载波上发送上行信号的时候，可以以第二下行载波的第二下行配置信息为依据。终端设备不需要从第二下行载波上接收下行业务数据，但可以通过第二上行载波向网络设备发送上行业务数据。举例来说，在本申请中，第二下行载波与第二上行载波为系统级成对的一对FDD载波，或者第二下行载波与第二上行载波为系统级成对的一对TDD载波。但是，本申请中涉及的第二下行载波、以及第二上行载波可以是其他终端设备的服务载波，例如，第二下行载波和第二上行载波可以作为其他支持LTE的终端设备的一对服务载波，或者，第二下行载波和第二上行载波可以作为其他支持NR的终端设备的一对服务载波；当第二下行载波和第二上行载波作为其他终端设备的一对服务载波的时候，也可以在终端设备在第二下行载波上接收网络设备发送的广播消息，此时，的广播消息中可以包括第二上行载波的频点信息、带宽信息等等配置信息，以及第二上行载波 上的随机接入配置信息等等。
其中，在本申请中，网络设备在第一下行载波上向当前的终端设备发送的广播消息，其具体名称在本申请中不做限定；并且，该广播消息中的信息可以由一条广播消息或多条广播信息承载，或者，该广播消息中的信息可以由高层信令中的一个或多个信息元素(Information Element)进行承载，即在本申请中终端设备接收到的广播消息也不限定为一条广播消息或一条广播信道。举例来说，第一下行载波本身的小区基本信息、第二上行配置信息、第二下行配置信息可以分别承载在不同的广播消息里，例如，第一下行载波的小区基本信息承载在NR主系统模块(Master Information Block，MIB)里，同时将第二上行配置信息以及第二下行配置信息承载在NR系统信息块(System Information Block，SIB)里，再例如，将第一下行载波本身的小区基本信息、第二上行配置信息、第二下行配置信息都承载在NR SIB里。进而，终端设备通过检测NR同步信号来发现该第一下行载波，例如通过NR主同步序列(Primary Synchronization Sequence，PSS)和辅同步序列(Secondary Synchronization Sequence，SSS)来发现该第一下行载波，举例来说，终端设备可以通过NR PSS和SSS的序列信息来识别该第一下行载波，然后终端设备读取网络设备在该第一下行载波上发送的广播信息。
本实施例通过终端设备在第一下行载波上接收网络设备发送的广播消息，其中，广播消息中包括与第二下行载波对应的第二下行配置信息；其中，第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第一下行载波与第二上行载波属于终端设备的服务载波，且第二下行载波不属于终端设备的服务载波；第二下行载波与第二上行载波为系统级成对的载波。从而终端设备在第一下行载波上获取到网络设备发送的与第二下行载波对应的第二下行配置信息，其中，第一下行载波属于终端设备的服务载波，但是第二下行载波不属于终端设备的服务载波，终端设备可以根据与第二下行载波对应的第二下行配置信息，确定出在第二上行载波上发送信号时所依据的参考信息，其中，第二上行载波属于终端设备的服务载波。进而终端设备可以从第一下行载波上获取到不是当前的终端设备的服务载波的配置信息，便于在终端设备依据不是当前的终端设备的服务载波的配置信息，去进行上行信号的发送。进一步的，不采用NR高频下行载波所对应的配置信息来获取到的下行的参考信息，去进行LTE低频上行载波上信号的发送，而是可以通过承载在NR高频下行载波上的LTE低频下行载波配置信息，去进行LTE低频上行载波上信号的发送，有助于提高NR与LTE共存场景下的系统的性能。
图5为本申请实施例提供的又一种信息收发方法的流程示意图。如图5所示，在图3所示的实施例的基础上，该方法，包括：
S201、终端设备在第一下行载波上接收网络设备发送的广播消息，其中，广播消息中包括与第二下行载波对应的第二下行配置信息、第二上行载波上的随机接入配置信息。其中，第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第一下行载波与第二上行载波属于终端设备的服务载波，且第二下行载波不属于终端设备的服务载波；第二下行载波与第二上行载波为系统级成对的载波。
S202、终端设备在第二上行载波上，依据随机接入配置信息进行随机接入。
S203、终端设备根据第二下行配置信息，确定第二下行载波的参考信息。其中，参考 信息，包括以下的至少一种：参考路径损耗、参考下行接收定时、参考时间同步信息、参考频率同步信息。
S204、终端设备依据第二下行载波的参考信息，在第二上行载波上向网络设备发送上行信号。
在S201之后，还包括：
S205、终端设备根据第二下行配置信息，对第二下行载波进行RRM测量，得到测量结果；终端设备根据测量结果，对第二上行载波进行移动性管理。
其中，S202-S204，与S205之间可以单独实施，也可以同时实施，本申请不做限定。
图6为本申请实施例提供的又一种信息收发方法的信令图一，图6用于执行图5所提供的又一种信息收发方法的流程，如图6所示，该方法包括：
S21、终端设备在第一下行载波上接收网络设备发送的广播消息，其中，广播消息中包括与第二下行载波对应的第二下行配置信息、以及第二上行载波上的随机接入配置信息。
其中，第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第一下行载波与第二上行载波属于终端设备的服务载波，且第二下行载波不属于终端设备的服务载波；第二下行载波与第二上行载波为系统级成对的载波。
在本实施例中，网络设备在第一下行载波上发送广播消息，网络设备所管辖范围内的终端设备根据自身的需求，在第一下行载波上接收该广播消息。本步骤的过程参见图4所提供的一种信息收发方法的信令图中的步骤S11，原理和过程与步骤S11相同。
但是在图6中的S21中，广播消息中还会包括第二上行载波上的随机接入配置信息，该随机接入配置信息可以为前导的序列相关信息和/或时频资源信息等。
S22、终端设备在第二上行载波上，依据随机接入配置信息进行随机接入。
在本实施例中，终端设备在检测到广播消息之后，终端设备首先需要根据随机接入配置信息进行随机接入。终端设备可以采用现有的任一随机接入方法，根据随机接入配置信息进行随机接入。本实施例对于随机接入的方法不做限定。
举例来说，图7为本申请实施例提供的又一种信息收发方法中的随机接入过程的信令图，如图7所示，终端设备需要在第二上行载波上进行随机接入，步骤S1为终端设备向网络设备发送消息1，消息1为前导符(Preamble)，Preamble是接入信道的前导码；步骤S2为网络设备向终端设备返回消息2，消息2为随机接入响应消息；步骤S3为终端设备向网络设备发送消息3，其中，一般情况下，消息3是RRC类型的消息，但是由媒体介入控制层(Media Access Control，MAC)发起的时候消息3不是RRC类型的消息，例如，消息3中可以包括RRC消息，如service request、resume request，或者MAC层发起的随机接入；步骤S4为网络设备向终端设备返回消息4，消息4为竞争解决消息；终端设备就可以根据该竞争解决消息确定当前的随机接入过程竞争成功。
再举例来说，终端设备需要根据随机接入配置信息进行随机接入的时候，也可以采用两步随机方法，在两步随机接入过程中，终端设备可以向网络设备发送消息1和消息3，消息1为前导符Preamble；网络设备向终端设备返回消息2和消息4，消息2为随机接入响应消息，消息4为竞争解决消息。最终终端设备可以与网络设备建立起RRC 连接。
S23、终端设备根据第二下行配置信息，确定第二下行载波的参考信息。其中，参考信息，包括以下的至少一种：参考路径损耗、参考下行接收定时、参考时间同步信息、参考频率同步信息。
在本实施例中，终端设备需要依据第二下行配置信息，计算出第二下行载波的参考信息。在计算出第二下行载波的参考信息的时候，可以计算出参考路径损耗、参考下行接收定时、参考时间同步信息、参考频率同步信息中的任意一种或几种。
本申请中，计算出第二下行载波的参考路径损耗的过程如下：
与第二下行载波对应的第二下行配置信息中，会携带第二下行载波上的参考信号的配置发送功率值，其中，参考信号可以为小区特定参考信号(Cell-specific Reference Signal，CRS)或其他参考信号，比如信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，该参考信号的序列由第二下行配置信息中包括的物理小区标识确定；终端设备可以根据第二下行配置信息，测量在第二下行载波上发送的参考信号，进而在测量的过程中得到测量该参考信号时的接收功率值；然后终端设备根据第二下行配置信息中包括的参考信号的发送功率值、以及测量得到的接收功率值，得到与第二下行载波的频率相对应的参考路径损耗；然后终端设备就可以根据确定出的参考路径损耗，计算出终端设备在第二上行载波上发送的上行信号的实际发送功率值。例如，以LTE系统中的上行数据信道(Physical Uplink Shared Channel，PUSCH)为例，可以采用公式PL＝referenceSignalPower–higher layer filtered RSRP，其中，PL为参考路径损耗，referenceSignalPower为高层信令通知的参考信号的配置发送功率值，higher layer filtered RSRP为终端设备根据第二下行配置信息，测量在第二下行载波上发送的参考信号时的接收功率值，其中，在测量得到该接收功率值的过程中，终端设备是作为接收端一侧的，从上述公式中可以得出，配置发送功率值与接收功率值相减之后，就可以到网络设备与终端设备之间的参考路径损耗PL的值；然后采用公式P PUSCH(i)＝min{P CMAX,10log 10(M PUSCH(i))+P O_PUSCH(j)+α(j)·PL+Δ TF(i)+f(i)}，得到终端设备在第二上行载波上发送的上行信号的实际发送功率值，其中，P CMAX是当前的终端设备被配置的最大发送功率，M PUSCH(i)是当前的PUSCH被分配的带宽，P O_PUSCH是高层信令配置的一个预设参数，α(j)为补偿因子，Δ TF(i)是与当前的PUSCH的与调制与编码策略(Modulation and Coding Scheme，MCS)相关的参数，f(i)是与闭环功率相关的功率调整值，i为子帧索引，j为不同场景下发送PUSCH的场景标识。其他的上行信道，例如上行控制信道、上行参考信号等，它们的实际发送功率值都可以采用上述公式类似的进行计算。
在图1所示的场景下，若第一下行载波为NR DL载波，第二下行载波为LTE DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与LTE DL载波对应的LTE DL配置信息，在该LTE DL配置信息中包括了LTE DL载波的参考信号的配置发送功率值；终端设备可以根据LTE DL配置信息，测量在LTE DL载波发送的参考信号，可以得到接收功率值；终端设备根据LTE DL配置信息中的配置发送功率值、以及当前计算出的接收功率值，计算得到与LTE DL载波的频率对应的参考路径损耗；终端设备根据该与LTE DL载波的频率对应的参考路径损耗，计算出终端设备在LTE UL载波上发送上行信号时的实际发送功率值。
现有技术中，若第一下行载波为NR DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与NR DL载波对应的NR DL配置信息，在该NR DL配置信息中包括了NR DL载波的参考信号的配置发送功率值；终端设备可以根据NR DL配置信息，测量在NR DL载波发送的参考信号，可以得到接收功率值；终端设备根据NR DL配置信息中的配置发送功率值、以及当前计算出的接收功率值，计算得到与NR DL载波的频率对应的参考路径损耗；终端设备根据该与NR DL载波的频率对应的参考路径损耗，计算出终端设备在LTE UL载波上发送上行信号时的实际发送功率值。
由于NR部署在高频段，一般在3.5GHz甚至几十GHz，但是LTE部署在低频段，一般在800MHz或2GHz，NR与LTE之间的频点相差较大。现有技术中，终端设备基于NR下行载波上发送的参考信号而测量得到的参考路径损耗，只能表征在NR频段内的参考路径损耗，而不能表征终端设备在LTE上行载波上发送上行信号时的参考路径损耗。
而在本申请中，基于LTE下行载波上发送的参考信号而测量得到的参考路径损耗，可以表征在LTE频段内的参考路径损耗，可以表征终端设备在LTE上行载波上发送上行信号时的参考路径损耗。从而本申请计算参考路径损耗的方式，与现有技术中基于NR下行载波上发送的参考信号而测量得到参考路径损耗的方式，更加准确。
本申请中，计算出第二下行载波的参考下行接收定时的过程如下：
终端设备可以根据第二下行配置信息，测量在第二下行载波上发送的下行信号，例如，下行信号可以是下行同步信号或下行参考信号等，进而测量得到第二下行载波的下行接收定时；然后终端设备以该下行接收定时为基准，将该下行接收定时加上预设的当前的上行发送定时提前量，去得到一个上行发送定时，该上行发送定时也可以称作上行发送提前量。
在图1所示的场景下，若第一下行载波为NR DL载波，第二下行载波为LTE DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与LTE DL载波对应的LTE DL配置信息；图8为本申请实施例提供的又一种信息收发方法中的上行发送定时的计算示意图，如图8所示，为了规范帧结构，标准协议一般都是采用终端设备的上行发送提前的机制，从而，终端设备根据LTE DL配置信息，测量在LTE DL载波上发送的下行信号，得到一个LTE DL载波的下行接收定时N TA；终端设备根据下行接收定时N TA，以及当前的上行发送定时提前量N TA offset，可以得到上行发送定时，例如，终端设备可以采用公式(N TA+N TA offset)×T s得到上行发送定时，其中，T s为基本时间单位。
现有技术中，若第一下行载波为NR DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与NR DL载波对应的NR DL配置信息；终端设备根据NR DL配置信息，测量在NR DL载波上发送的下行信号，得到一个NR DL载波的下行接收定时N′ TA；终端设备根据下行接收定时N′ TA，以及当前的上行发送定时提前量N′ TA offset，可以得到上行发送定时，例如，终端设备可以采用公式(N′ TA+N′ TA offset)×T s得到上行发送定时。
由于NR与LTE之间的频点相差较大。可以看出，在现有技术中，NR DL载波与LTE UL载波的如频点相差较大，并且，由于LTE系统中FDD小区之间是异步的，而NR系统中很可能为了采用高级干扰协调和干扰删除等技术要求小区间同步，从而NR DL载波与 LTE UL载波的帧定时都有可能不一样，因此，现有技术中，终端设备根据NR DL载波的下行接收定时，去确定出与LTE UL载波对应的上行发送定时的方式，是不准确的。
而在本申请中，终端设备根据LTE DL载波的下行接收定时，去确定出与LTE UL载波对应的上行发送定时的方式更加准确。
本申请中，计算出第二下行载波的参考时间同步信息和/或参考频率同步信息的过程如下：
终端设备可以根据第二下行配置信息，测量在第二下行载波上发送的下行信号，例如，下行信号可以是下行同步信号或下行参考信号等，进而可以测量得到第二下行载波的参考时间同步信息和/或参考频率同步信息；然后，终端设备根据第二下行载波的参考时间同步信息和/或参考频率同步信息，去获取终端设备在第二上行载波上发送上行信号的参考时间同步信息和/或参考频率同步信息。
在图1所示的场景下，若第一下行载波为NR DL载波，第二下行载波为LTE DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与LTE DL载波对应的LTE DL配置信息；终端设备根据LTE DL配置信息，测量在LTE DL载波上发送的下行信号，得到LTE DL载波的参考时间同步信息和/或参考频率同步信息；然后，终端设备根据LTE DL载波的参考时间同步信息和/或参考频率同步信息，去获取终端设备在LTE UL载波上发送上行信号的参考时间同步信息和/或参考频率同步信息。
现有技术中，若第一下行载波为NR DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与NR DL载波对应的NR DL配置信息；终端设备根据NR DL配置信息，测量在NR DL载波上发送的下行信号，得到一个NR DL载波的参考时间同步信息和/或参考频率同步信息；然后，终端设备根据NR DL载波的参考时间同步信息和/或参考频率同步信息，去获取终端设备在LTE UL载波上发送上行信号的参考时间同步信息和/或参考频率同步信息。
由于NR与LTE之间的频点相差较大。可以看出，在现有技术中，NR DL载波与LTE UL载波的如频点相差较大，终端设备根据NR DL载波的参考时间同步信息和/或参考频率同步信息，去获取终端设备在LTE UL载波上发送上行信号的参考时间同步信息和/或参考频率同步信息的方式，并不准确。
本申请中，终端设备根据LTE DL载波的参考时间同步信息和/或参考频率同步信息，去获取终端设备在LTE UL载波上发送上行信号的参考时间同步信息和/或参考频率同步信息方式，更加准确。
S24、终端设备依据第二下行载波的参考信息，在第二上行载波上向网络设备发送上行信号。
在本实施例中，终端设备确定出第二下行载波的参考信息之后，就可以根据该第二下行载波的参考信息在第二上行载波上向网络设备发送上行信号了。其中，本申请不对上行信号的具体内容做限定，举例来说，上行信号可以为上行数据信道、上行控制信道和上行参考信号中的至少一种。
图9为本申请实施例提供的又一种信息收发方法的信令图二，图9用于执行图5所提供的又一种信息收发方法的流程，如图9所示，该方法包括：
S31、终端设备在第一下行载波上接收网络设备发送的广播消息，其中，广播消息中包括与第二下行载波对应的第二下行配置信息、以及第二上行载波上的随机接入配置信息。
其中，第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第一下行载波与第二上行载波属于终端设备的服务载波，且第二下行载波不属于终端设备的服务载波；第二下行载波与第二上行载波为系统级成对的载波。
在本实施例中，网络设备在第一下行载波上发送广播消息，网络设备所管辖范围内的终端设备根据自身的需求，在第一下行载波上接收该广播消息。本步骤的过程参见图4所提供的一种信息收发方法的信令图中的步骤S11，原理和过程与步骤S11相同。
S32、终端设备根据第二下行配置信息，对第二下行载波进行RRM测量，得到测量结果；终端设备根据测量结果，对第二上行载波进行移动性管理。
在本实施例中，由于第二下行载波不是终端设备的服务载波，但是与第二下行载波有系统级对应关系的第二上行载波是终端设备的服务载波，从而为了维持终端设备在低频段的第二上行载波上的移动性，就需要终端设备在第二下行载波上做RRM测量，RRM测量可以具体为参考信号接收功率(Reference Signal Receiving Power，RSRP)测量、或参考信号接收质量(Reference Signal Receiving Quality，RSRQ)测量等等，进而终端设备才可以利用测量得到的测量结果对作为当前终端设备的服务载波的第二上行载波进行移动性管理。在S25中，在终端设备检测到第二下行配置信息中的第二下行载波的第二下行频点信息和/或物理小区标识信息之后，终端设备就可以根据第二下行频点信息和/或物理小区标识信息，对第二下行载波进行下行的RRM测量了，可以得到一个测量结果；然后，终端设备就可以利用该测量结果，进行第二上行载波进行移动性管理。其中，移动性管理包括了以下的至少一种：是否更换第二上行载波、是否去配置第二上行载波。
在图1所示的场景下，若第一下行载波为NR DL载波，第二下行载波为LTE DL载波，第二上行载波为LTE UL载波，终端设备在NR DL载波上接收到网络设备发送的广播消息，在广播消息中包括了与LTE DL载波对应的LTE DL配置信息；终端设备根据LTE DL配置信息，对LTE DL载波进行RRM测量，得到一个测量结果；终端设备根据测量结果，对LTE UL载波进行移动性管理。
本实施例通过终端设备在第一下行载波上接收网络设备发送的广播消息，其中，广播消息中包括与第二下行载波对应的第二下行配置信息；其中，第二下行配置信息中包括第二下行载波的第二下行频点信息和/或物理小区标识信息；第一下行载波与第二上行载波属于终端设备的服务载波，且第二下行载波不属于终端设备的服务载波；第二下行载波与第二上行载波为系统级成对的载波；终端设备根据第二下行配置信息，确定第二下行载波的参考信息；终端设备依据第二下行载波的参考信息，在第二上行载波上向网络设备发送上行信号。从而终端设备在第一下行载波上获取到网络设备发送的与第二下行载波对应的第二下行配置信息，其中，第一下行载波属于终端设备的服务载波，但是第二下行载波不属于终端设备的服务载波，终端设备可以根据与第二下行载波对应的第二下行配置信息，确定出在第二上行载波上发送信号时所依据的参考信息，其中，第二上行载波属于终端设备的服务载波。进而终端设备可以从第一下行载波上获取到不是当前的终端设备的服务载波的配置信息，便于在终端设备依据不是当前的终端设备的服务载波的配置信息，去进行上 行信号的发送。不采用NR高频下行载波所对应的配置信息来获取到的下行的参考信息，去进行LTE低频上行载波上信号的发送，而是可以通过承载在NR高频下行载波上的LTE低频下行载波配置信息去获取参考信息，根据该参考信息去进行LTE低频上行载波上信号的发送，有助于提高NR与LTE共存场景下的系统的性能。
