Description

一种发送信号的方法及设备
本申请要求在2017年8月11日提交中国专利局、申请号为201710687885.0、发明名称为“一种发送信号的方法及设备”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
本申请涉及无线通信技术领域，尤其涉及一种发送信号的方法及设备。
背景技术
目前，在第五代移动通信系统中，主要提出了两种类型的基站，分别为长期演进(Long Term Evolution，LTE)基站和新空口(New Radio，NR)基站。对于这两种类型的基站，功能相类似，主要区别为部署频段的不同。在现有技术中，NR基站主要部署在高频频段，而LTE基站主要部署在低频频段。由于在无线通信系统中，载波的频率越高，路径损耗越大，上行覆盖越差，而NR基站由于部署在高频频段，因此，NR基站存在上行覆盖受限的问题。
为了解决NR基站上行覆盖受限的问题，相关技术人员提出了如下解决方案：在LTE基站的上行负载较低时，NR基站将共享LTE基站的上行载波资源，如此，既能提高LTE基站的上行资源利用率，又可提高NR基站的上行覆盖。比如，如图1a所示，LTE基站的上行工作频段为1.75GHz，下行工作频段为1.85GHz，上行工作频段1.75GHz与下行工作频段1.85GHz相绑定。NR基站的上行工作频段和下行工作频段均为3.5GHz。在LTE基站的上行负载较低时，NR基站可利用LTE基站的1.75GHZ的上行载波进行上行通信。当然，如图1b所示，NR基站也可以利用上行补充(supplementary uplink，SUL)载波进行上行通信，在该SUL载波上可以不部署LTE系统。
同时，在现有技术中，终端设备可以通过如下方式接入基站：
步骤A：接收基站的下行同步信号，根据所述下行同步信号，与基站保持同步；
步骤B：接收基站发送的通知消息，所述通知消息中携带有信道编号；
步骤C：根据所述信道编号计算上行载波的频率或者中心频率，比如，可根据下述公式，计算上行载波的频率，F UL＝F UL_low+0.1(N UL–N Offs-UL)，所述F UL代表上行载波的频率，F UL_low为上行载波的最低上行频率，所述N UL代表信道编号，所述N Offs-UL代表上行载波的最低上行频率号；
步骤D：将上行子载波映射到上行载波上；
步骤E：利用映射后的上行子载波进行上行传输。
在现有技术中，如图2所示，主要有两种子载波映射方式，分别为第一映射方式和第二映射方式。其中，第一映射方式为将上行子载波的中心映射到上述计算出的上行载波的频率，第二映射方式为将上行子载波的中心映射到相对于上行载波的频率偏移7.5KHz的频率处。
为方便描述，以下定义了两种终端，分别为LTE终端和NR终端，所述LTE终端为选 择LTE基站作为服务基站的终端，所述NR终端为选择NR基站作为服务基站的终端。目前，对于LTE终端的上行数据传输通常采用第二种方式进行映射，而NR终端的上行数据传输通常采用第一种方式进行映射。而当NR基站共享LTE基站的上行资源进行上行数据传输时，为了避免与LTE终端相互干扰，NR终端可以采用第二种方式进行映射。因此可见，在第五代移动通信系统中，由于NR终端支持两种映射方式，那么当NR终端在上行传输时，采用第一映射方式，还是第二映射方式，并没有较好的解决方案。

具体实施方式
为了便于理解，示例的给出了与本申请相关概念的说明以供参考，如下所示：
终端设备是一种用户设备(user equipment，UE)，可以是可移动的终端设备，也可以是不可移动的终端设备。该设备主要用于接收或者发送业务数据。用户设备可分布于网络中，在不同的网络中用户设备有不同的名称，例如：终端，移动台，用户单元，站台，蜂 窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台，车载设备等。该用户设备可以经无线接入网(radio access network，RAN)(无线通信网络的接入部分)与一个或多个核心网进行通信，例如与无线接入网交换语音和/或数据。
网络设备是一种部署在无线接入网中为终端设备提供无线通信功能的装置。网络设备可以包括各种形式的基站，包括宏基站、微基站(也称为小站)、中继站及接入点等。在采用不同的无线接入技术的系统中，具备网络接入功能的设备的名称可能会有所不同。例如，网络设备可以是5G系统中诸如gNB、收发点(transmission and reception point，TRP)，或传输点(transmission point，TP)之类的网络设备，或者未来演进的公共陆地移动网络(public land mobile network，PLMN)系统中的网络设备，可以是无线局域网(wireless local area networks，WLAN)中的接入点(access point，AP)，还可以是LTE系统或LTE-A系统中的演进的节点B(evolved NodeB，eNodeB)、第三代(3rd generation，3G)系统的节点B(Node B)等。另外，该网络设备还可以是车载设备或可穿戴设备。其中，TRP或TP可以不包括基带部分，仅包括射频部分，也可以包括基带部分和射频部分。
下面结合附图，对本申请的技术方案进行介绍：
图3示出了本申请一种可能的系统网络示意图。如图3所示，图3中的通信系统可以包括终端设备10和基站20。基站20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索基站20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图3中所示出的箭头可以表示通过终端设备10与基站20之间的无线通信网络进行的上/下行传输。
该通信系统可以是新无线电(new radio，NR)通信系统，长期演进技术(long term evolution，LTE)系统，或长期演进高级技术(long term evolution-advanced，LTE-A)系统，也可以扩展到类似的无线通信系统中，如第三代合作伙伴计划(3rd generation partnership project，3gpp)相关的蜂窝系统。
图4为本申请提供的一种发送信号的方法的流程，该流程中的终端设备对应于图3中的终端设备10，网络设备可对应于图3中的基站20，如图4所示，包括：
步骤S41：网络设备向终端设备发送第一信息。
其中，所述第一消息可具体为广播消息，也可具体为系统消息，所述第一信息中包括信道编号的指示信息和信道栅格值的指示信息中的至少一个，所述信道编号具体用于标识上行载波，在本申请中，可称为绝对无线频道号，也可称为其它名称。与所述信道编号功能相似类的其它名称，均在本申请的保护范围内。
步骤S42：终端设备根据所述第一信息确定上行子载波的映射方式。
其中，如图5所示，所述上行子载波的映射方式为第一映射方式，或者第二映射方式，所述第一映射方式为所述上行子载波的中心映射在第一频率，所述第一频率包括上行载波的频率，所述第二映射方式为所述上行子载波的中心映射在第二频率，所述第二频率与所述第一频率有偏移值，所述偏移值为+7.5KHz或者-7.5KHz等，也可以是其他值，比如22.5KHz，52.5KHz等；所述上行载波的频率可为上行载波的中心频率，也可为上行载波中除中心频率外的其它频率，所述上行载波的频率也可称为参考频率。
步骤S43：所述终端设备根据所述上行子载波的映射方式向所述网络设备发送上行信号。
在本申请中，所述终端设备可根据所述上行子载波的映射方式，对所述上行子载波进行映射，且利用映射后的上行子载波，向所述网络设备发送上行信号。
由上可见，在本申请中，网络设备可向终端设备发送第一信息，而终端设备设备可根据第一信息，确定上行子载波的映射方式，且利用映射后的上行子载波向网络设备发送上行信号。可以看出，采用本申请的方法，终端设备可确定上行子载波的映射方式。
在本申请的一示例中，第一信息中可仅携带信道编号的指示信息，所述第一信息可具体为广播信息，所述终端设备关于如何确定上行子载波的映射方式，具体如下：
第一种：终端设备可根据信道编号的指示信息，以及信道编号与映射方式的对应关系，确定上行子载波的映射方式
在本申请中，终端设备可首先根据信道编号的指示信息，确定信道编号；然后根据信道编号与映射方式的对应关系，确定上行子载波的映射方式，比如，所述信道编号与映射方式的对应关系，可为当信道编号为奇数时，对应于第一种映射方式，而当信道编号为偶数时，对应于第二种映射方式。
第二种：终端设备可根据第一信息中包括的信道编号的指示信息以及信道编号与信道栅格值的对应关系，确定所述终端设备当前使用的第一信道栅格值；然后根据所述当前使用的第一信道栅格值确定所述上行子载波的映射方式。
在本申请中，终端设备可首先根据信道编号的指示信息，确定信道编号；然后根据信道编号与绝对无线频道与信道栅格值的对应关系，确定第一信道栅格值，所述第一信道栅格值可具体为100KHz、180KHz或者300KHz。最后，根据第一信道栅格值，确定上行子载波的映射方式，比如，可具体根据第一信道栅格值以及信道栅格值与映射方式的对应关系，确定上行子载波的映射方式。
第三种：终端设备根据所述第一信息中的信道编号的指示信息，确定上行频段；所述终端设备在所述上行频段的类型为第一类型时，确定所述上行子载波的映射方式为所述第一映射方式，所述第一类型包括新空口NR专用类型，所述第一类型是指该上行频段为NR系统专用的上行频段。所述终端设备在所述上行频段的类型为第二类型时，确定所述上行子载波的映射方式为所述第二映射方式，所述第二类型包括长期演进LTE与NR共享类型或上行补充(supplementary uplink，SUL)类型，所述第二类型是指该上行频段为NR系系统和LTE系统共享的上行频段，或者NR中的SUL频段。
在本申请中，终端设备可首先根据第一信息中的信道编号的指示信息，确定信道编号；然后根据信道编号，确定上行频段，比如，可根据信道编号，确定上行载波的频率，然后根据上行载波的频率，确定上行载波，最后，确定上行载波，所对应的上行频段，再如，可根据信道编号，确定上行载波的频率，然后根据上行载波的频率，与上行载波的频率与映射方式的对应关系，确定上行载波的映射方式。
在本申请中，可具体利用下公式，计算上行载波的频率：
F UL＝F UL_low+M(N UL–N Offs-UL)，所述F UL代表上行载波的频率，F UL_low为上行载波的最低上行频率，所述N UL代表信道编号，所述N Offs-UL代表上行载波的最低上行频率号，所述M代表信道栅格值。
第四种：终端设备根据所述第一信息中的信道编号的指示信息，确定上行频段；所述终端设备在所述上行频段的类型为第一类型时，确定所述上行子载波的映射方式为所述第 一映射方式；
在所述上行频段的类型为第二类型时，获取所述上行载波的频率，在所述上行载波的频率为第二信道栅格值的整数倍时，确定所述上行子载波的映射方式为所述第二映射方式，所述第二信道栅格值为LTE系统的信道栅格值，比如100KHZ；否则，确定所述上行子载波的映射方式为所述第一映射方式。
在本申请中，关于第一类型和第二类型的说明，可参见上述第三种方式的记载，在此不再赘述。由于LTE系统的上行载波的频率为第二信道栅格值的整数倍，因此，在本申请中，在终端设备的上行载波的频率为第二信道栅格值的非整数倍时，本申请中的终端设备与LTE系统的终端设备的上行载波是不能对齐的，因此，在此种情况下，本申请中的终端设备可直接采用终端设备原来支持的第一映射方式。
第五种：终端设备根据所述第一信息中的信道编号的指示信息，确定上行频段；
所述终端设备在所述上行频段的类型为第一类型时，确定所述上行子载波的映射方式为所述第一映射方式；
在所述上行频段的类型为第二类型时，确定所述终端设备当前使用的第一信道栅格值；
在所述第一信道栅格值为第二信道栅格值的整数倍时，确定所述上行子载波的映射方式为所述第二映射方式，所述第二信道栅格值为LTE系统的信道栅格值，否则，确定所述上行子载波的映射方式为所述第一映射方式。
在本申请中，由于NR系统的上行载波的中心频率为终端设备当前使用的第一信道栅格值的整数倍，而LTE系统的终端设备的上行载波的中心频率为第二信道栅格值的整数倍，因此，在本申请中，当终端设备当前使用的第一信道栅格值为LTE系统的第二信道栅格值的非整数倍时，可直接确定当前终端设备上行载波的中心频率并不能与LTE系统的上行载波的中心频率相对齐，因此，在此种情况下，本申请中的终端设备可直接采用终端设备原来支持第一映射方式。
在本申请的另一示例中，第一信息中可仅携带信道栅格值的指示信息，所述终端设备关于如何确定上行子载波的映射方式，具体如下：
第一种：终端设备可根据所述第一信息中的信道栅格值的指示信息，确定所述终端设备当前使用的第一信道栅格值；
在本申请中，终端设备可具体支持三种信道栅格值，分别为100KHz、180KHz和300KHz。而第一信息中信道栅格值的指示信息，可具体有三种状态，如表1所示，分别为状态1、状态2以及状态3，且状态1与100KHz相对应，状态2与180KHz相对应，状态3与300KHz相对应。
指示信息 信道栅格值
状态1 100KHz
状态2 180KHz
状态3 300KHz
表1
在本申请中，当终端设备所接收的第一信息中信道栅格值的指示信息为状态1时，可确定终端设备当前使用的第一信道栅格值为100KHz，信道栅格值的指示信息为状态2时， 可确定终端设备当前使用的第一信道栅格值为180KHz，相应的，当为状态3时，可确定终端设备当前使用的第一信道栅格值为300KHz。
在本申请中，终端设备也可具体支持二种信道栅格值，分别为100KHz和180KHz。而第一信息中信道栅格值的指示信息，可具体有二种状态，如表2所示，分别为状态1和状态2，且状态1与100KHz相对应，状态2与180KHz相对应。
指示信息 信道栅格值
状态1 100KHz
状态2 180KHz
表2
同上述，当终端设备所接收的第一信息中信道栅格值的指示信息为状态1时，可确定终端设备当前使用的第一信道栅格值为100KHz，同理，当为状态2时，可确定终端设备当前使用的第一信道栅格值为180KHz。
需要说明的是，在本申请中，终端设备所支持的信道栅格值并不限于上述2种或3种，支持3种以上的情况，也在本申请的保护范围内。
所述终端设备在所述当前使用的第一信道栅格值为第一值时，获取第二信息，所述第二信息用于指示所述终端设备所使用的上行子载波映射方式，所述第一值包括LTE系统的信道栅格值，比如，第一值可为100KHz。
在本申请中，关于终端设备获取第二信道的方式具体有两种，一种为网络设备将第一信息和第二信息打包成一数据包发送至终端设备，而终端设备在接收到该数据包后，首先获取该数据包中的第一信息，然后，根据所述第一信息中信道栅格值的指示信息，确定终端设备当前使用的信道栅格值，且在当前使用的信道栅格值为第一值时，再从该数据包中获取第二信息。另一种为网络设备接收第一信息，且根据第一信息，确定终端设备当前使用的信道栅格值，且在该信道栅格值为第一值时，再执行接收第二信息的操作。
终端设备根据所述第二信息确定所述上行子载波的映射方式。
在本申请中，所述第二信息可具体为上行子载波映射方式的指示信息，该指示信息可具体指示终端设备的上行子载波的映射方式，比如，第二信息指示第一映射方式，则终端设备可确定上行子载波的映射方式为第一映射方式；同理，当第二信息指示第二映射方式时，则终端设备可确定上行子载波的映射方式为第二映射方式。
所述终端设备在所述当前使用的第一信道栅格值为第二值时，确定上行子载波的映射方式为预设映射方式，所述预设映射方式为所述第一映射方式，或所述第二映射方式，所述第二值与所述第一值不相同。所述第二值可具体为180KHz或300KHz等。
由上可见，在上述方式中，终端设备在确定当前使用的信道栅格值为第一值时，具体采用的上行子载波的映射方式需根据第二信息的指示，而当终端设备在确定当前使用的信道栅格值为第二值时，其采用的上行子载波的映射方式可预定义。
第二种：所述终端设备根据所述第一信息中的信道栅格值的指示信息，确定所述终端设备当前使用的第一信道栅格值；
关于如何确定终端设备当前使用的第一信道栅格值，可参见上述表1和表2的记载。
所述终端设备根据所述第一信道栅格值以及信道栅格值与上行子载波映射方式的对应关系，确定所述上行子载波的映射方式。
在本申请中，终端设备侧可具体存储有信道栅格值与上行子载波映射方式的对应关系，比如，所终端设备支持2种信道栅值时，所述信道栅格值与上行子载波映射方式的对应关系，可如表3所示。而当终端设备支持3种信道栅值时，所述信道栅格值与上行子载波映射方式的对应关系，可如表3所示。

表4
由上可见，在第二种方式时，网络设备仅需发送信道栅格值的指示信息，而终端设备可根据信道栅格值的指示信息，确定当前使用的第一信道栅格值和子载波的映射方式，从而节省信令开销。
在本申请的另一示例中，第一信息中同时携带信道编号的指示信息和信道栅格值的指示信息，而终端设备可根据该指示信息，同时确定出子载波的映射方式和当前使用的第一信道栅格值。
比如，如表5所示，当终端设备支持两种信道栅格值时，分别为100KHz和180KHz，第一信息中的指示信息可具体为状态1和状态2，其中状态1对应100KHz的信道栅格值和第二种子载波映射方式，状态2对应180KHz的信道栅格值和第一种子载波映射方式。
Figure PCTCN2018097824-appb-000003
表5
再如，如表6所示，当终端设备支持三种信道栅格值时，分别为100KHz、180KHz和300KHz，第一信息中的指示信息可具体为状态1、状态2和状态3，其中，状态1对应100KHz的信道栅格值和第二种子载波映射方式，状态2对应180KHz的信道栅格值和第一种子载波映射方式，状态3对应于300KHz的信道栅格值和第一种子载波的映射方式。
Figure PCTCN2018097824-appb-000004
表6
由上可见，在示例中，网络设备可通过一个指示信息，同时指示信道栅格值和子载波映射方式，可进一步节省信令开销。
