Description

信号发送方法、接收方法及发送设备、接收设备
相关申请的交叉引用
本申请主张在2018年9月26日在中国提交的中国专利申请号No.201811126458.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种信号发送方法、接收方法及发送设备、接收设备。
背景技术
在sidelink(旁链路)上传输的存在两种终端：
1.配置A终端：网络侧设备发送当前载波上sidelink传输资源的分配，终端接收分配信息后，选择并根据网络侧设备指示的sidelink传输资源，进行sidelink传输。
2.配置B终端：终端从厂商预配置的资源池中选择sidelink传输资源。
对于配置A的终端，它可以从网络侧设备获取tdd-config和sidelink同步资源的相关信息。对于配置B的终端,通常是因为没有网络覆盖，只能从厂商预配置中获取tdd-config和确定sidelink同步资源。
相关技术存在以下问题：
第一方面，NR中网络支持上下行配置非常灵活，指示该配置所需的开销信令比LTE大了很多。一方面，厂商预配置的上下行配置的数目和灵活性有限，网络配置的上下行配置和厂商预配置的上下行配置很可能会不同，导致不同模式的终端互相干扰。即使在两种模式的终端定时对齐或者同步源相同，并且使用相同sidelink资源的时候，两种终端对于DFN理解也可能不同，从而也会造成相互干扰。
第二方面，不同的终端可能选择了相同的同步源、sidelink同步资源和同步信号序列，但是MIB-SL-V2X中携带的内容可能相同也可能不同，此时接 收端终端可能在一块资源上收到多个发送设备的同步信号序列和MIB-SL-V2X，然而接收端无法通过检测同步信号序列直接区分出存在不同MIB-SL-V2X，并且也无法通过解码出不同的MIB-SL-V2X而唯一地确定其发送设备，因此测量出的结果实际上是多个发送设备信号的叠加，并不准确，在多波束的场景下也无法进行波束相关的操作。

具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
在sidelink(旁链路)上传输的存在两种终端：
1.配置A终端：网络侧设备发送当前载波上sidelink传输资源的分配，终端接收分配信息后，选择并根据网络侧设备指示的sidelink传输资源，进行sidelink传输。
2.配置B终端：终端从厂商预配置的资源池中选择sidelink传输资源。
在长期演进(Long Term Evolution，LTE)sidelink中，sidelink重用了LTE的上行资源。sidelink终端在sidelink上发送主旁链路同步信号(primary sidelink synchronization signal，PSSS),副旁链路同步信号(Secondary SIDelink Synchronization,SSSS),旁链路主信息块(MasterInformationBlock-SL-V2X，MIB-SL-V2X)，其中PSSS,SSSS用于帮助接收终端获取子帧级别的定时信息，LTE sidelink中PSSS序列是ZC序列，但是采用了和LTE主同步信号(primary synchronization signal，PSS)的不同的逻辑根，因此PSSS序列和LTE的PSS序列本质上是不同的序列。而SSSS重用了副同步信号(Secondary SIDelink Synchronization,SSS)的序列设计，在PSSS和PSS对应的标识(Identifier，ID)相同，SSSS和SSS对应的ID相同时，SSSS序列和SSS序列一样。
LTE V2V中PSSS和SSSS的时域结构如图1所示。
MIB-SL-V2X中携带了tdd-config，直接帧号(Direct Frame Number，DFN)和带宽等信息，DFN用于帮助接收终端获取发送终端的帧级别的定时信息，tdd-config上提供的是上行(Uplink，UL)/下行(Downlink，DL)的配置。为了简单，可以将用于传输PSSS，SSSS，MIB-SL-V2X的资源简称为sidelink同步资源。
对于配置A的终端，它可以从网络侧设备获取tdd-config和sidelink同步资源的相关信息。对于配置B的终端,通常是因为没有网络覆盖，只能从厂商预配置中获取tdd-config和确定sidelink同步资源。
配置A的终端会在它的MIB-SL-V2X中发送它从网络侧设备获得的tdd-config，DFN和带宽配置，而配置B的终端会在它的MIB-SL-V2X中发送厂商预配置的tdd-config，DFN和带宽。
终端先根据tdd-config确定无线资源中哪些是上行子帧，哪些是下行子帧和特殊子帧，随后终端从无线资源中删除下行子帧和sidelink同步资源占据的资源，将剩下的资源时间顺序排列，并且按照10ms为一个sidelink帧进行编号,编号即DFN。
一种示意图如图2所示，假设UL子帧都被重用于传输SL,其中SFN1中的子帧8用于SL同步信号的传输。
LTE中支持的上行/下行配置只有6种，并且配置的单位是子帧。而且新空口(New Radio，NR)中支持的上行/下行配置达到了几十种，配置的单位可以是符号，另外NR中还引入了flexible符号，网络侧设备可以动态地配置和改变flexible符号上的上行/下行配置，并且在后续演进中还可以继续拓展支持的配置数。
在NR中，NR基站需要发送同步信号块(SS block，SSB，也可以称为SS/PBCH block，同步信号/物理广播信号块)以供终端进行同步、系统信息获取、测量评估等。一个SSB由NR-SS和NR-PBCH(Physical Broadcast Channel，物理广播信道)两部分组成，其中NR-SS分为NR-PSS和NR-SSS两部分。一个SSB总共包含4个符号，一个SSB内这些符号的时域组成顺序是PSS-PBCH-SSS-PBCH.
对于某个频域，假设一个周期内最多发送L个SSB，则L个SSB是在一个5ms的时间窗内按照协议定义好的时域位置进行传输的，即SSB在周期性出现的一个5ms窗内传输。如图3所示，L＝4,子载波间隔SCS＝15kHz，一个slot(时隙)中有两个SSB，该5ms窗内承载有SSB的slot位置如图3所示。
由于一个无线帧的长度是10ms，而SSB时间窗只有5ms,因此基站会通过1bit的半帧指示(half frame indicator，HFI)来告知终端该时间窗位于一个无线帧的前半帧还是后半帧，并且基站还会指示每个SSB的指示(index)。
相关技术存在以下问题：
第一方面，NR中网络支持上下行配置非常灵活，指示该配置所需的开销信令比LTE大了很多。一方面，厂商预配置的上下行配置的数目和灵活性有限，网络配置的上下行配置和厂商预配置的上下行配置很可能会不同，导致不同模式的终端互相干扰。即使在两种模式的终端定时对齐或者同步源相同，并且使用相同sidelink资源的时候，两种终端对于DFN理解也可能不同，从而也会造成相互干扰。
第二方面，不同的终端可能选择了相同的同步源、sidelink同步资源和同步信号序列，但是MIB-SL-V2X中携带的内容可能相同也可能不同，此时接收端终端可能在一块资源上收到多个发送设备的同步信号序列和 MIB-SL-V2X，然而接收端无法通过检测同步信号序列直接区分出存在不同MIB-SL-V2X，并且也无法通过解码出不同的MIB-SL-V2X而唯一地确定其发送设备，因此测量出的结果实际上是多个发送设备信号的叠加，并不准确，在多波束的场景下也无法进行波束相关的操作。
为了解决上述问题，本公开实施例提供一种信号发送方法、接收方法及发送设备、接收设备，使得接收设备可以通过对信号的检测确定发送设备的信息，有利于后续的测量、合并、解码、管理等操作，提高传输的准确性。
