信号的发送、接收方法及终端
相关申请的交叉引用
本申请主张在2019年9月26日在中国提交的中国专利申请号No.201910919201.4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，尤其涉及一种信号的发送、接收方法及终端。
背景技术
在5G NR(NR Radio Access，新无线接入技术)V2X系统中,终端与终端之间使用PC5口(Sidelink，直通链路)进行直接通信。在进行业务数据传输之前，首先需要进行通信的两个终端之间在PC5口(Sidelink)建立同步。建立同步的方法就是一个终端A发送同步与广播信号，另外一个终端B接收终端A发送的同步与广播信号，一旦终端B接收并解调成功，这两个终端就能够建立同步，为下一步直接通信做好了准备。
NR UU口的同步信号是通过SSB(Synchronization Signal Block，同步信号块)携带的。每个Slot(时隙)中携带2个SSB块并且PSS(Primary Synchronization Signal，主同步信号)与SSS(Secondary Synchronization Signal，辅同步信号)没有时域重复机制。
为了完成波束测量与波束选择，NR UU口的SSB需要做波束扫描(Beam Sweeping)，波束扫描是指基站在一定的时间区间内(5ms)，将SSB在可能的各个波束方向上都发送一次，然后终端测量各个波束的SSB信号强度并将测量结果上报给基站，基站根据终端上报的测量结果，选择最合适的波束给终端发送数据。根据不同的载波频率与不同的子载波间隔，需要做波束扫描的方向的数量也是不同的。SSB波束扫描候选方向在不同的载频范围的最大值分别为：4/8/64个，实际配置的波束扫描方向的数量不能超过该最大值。
在相关的LTE V2X技术中(Rel-14/Rel-15 LTE V2X技术)，Sidelink直通链路上每160ms最多配置3个同步子帧，UE(User Equipment，用户设 备或者终端)在这些同步子帧上进行Sidelink同步信号与广播信息的发送与接收，并且UE在这些同步子帧上发送与接收同步信号与广播信息时，并不会进行波束扫描，同步信号与广播信息的覆盖范围较小。
随着5G NR的出现，促使车联网技术进一步发展，以满足新应用场景的需求。LTE V2X技术中UE在同步子帧上所进行的同步信号与广播信息的发送与接收的方法无法满足5G NR的新应用场景的需求。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地 理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示，为V2X Sidelink同步广播信息设计图，当UE准备在Sidelink上进行业务传输之前，首先需要在Sidelink上取得同步，为了扩大同步信号的覆盖范围，需要进行P-SSS/S-SSS信号的时域重复，以增强同步信号的检测性能。
按照图1所示，横坐标是时域，每列代表一个OFDM符号。纵坐标是频域，该图中是6RB。一个Slot里容纳了一个同步信号块(SSB)，一个同步信号块包括有S-PSS(Sidelink Primary Synchronization Signal，直通链路-主同步信号)、S-SSS(Sidelink Secondary Synchronization Signal，直通链路-辅同步信号)、S-PBCH(SidelinkPhysical Broadcast Channel，直通链路-物理广播信道)信号以及必要的DMRS(Demodulation Reference Signal，解调参考信号)信号。
在NR中，PBCH中包括的内容包括有：
系统定时信息：SFN(系统帧)，half radio frame(半广播帧)；
频域信息：
subCarrierSpacingCommon(公共子载波搜索)；
ssb-SubcarrierOffset(SSB的子载波偏移)；
dmrs-TypeA-Position(解调参考信号的类型A定位)；
pdcch-ConfigSIB1(物理下行控制信道的配置SIB1)；
MSB of the subcarrier offset between SSB and the common resource block grid(FR1)/SSB index(FR2)(ssb和公共资源块网格之间的子载波偏移量的msb)；
小区相关信息：cellBarred(小区接入禁止指示)，intraFreqReselection(同频重选:允许)。
NR PBCH中的一些内容由于不适用于V2X，所以不用出现在V2X PSBCH中，比如NR PBCH中的频域信息pdcch-ConfigSIB1用来指示initial BWP(初始带宽部分)的时频域位置以及PDCCH(物理下行控制信道)监听时机，该字段可以在V2X PSBCH中省略，用来传输V2X的其他信息。
第一实施例：
如图2所示，本公开的实施例提供一种信号的发送方法，应用于终端，所述方法包括：
在同步子帧或者时隙中，发送同步信号块SSB；所述SSB包括主同步信号PSS、辅同步信号SSS与物理广播信道PBCH；通过预配置的方式、所述PBCH、所述PBCH对应的解调导频参考信号DMRS和SSS中的至少一项，配置如下信息中的至少一项：终端在一个同步周期内实际发送的SSB的数量信息；所述SSB的时域位置信息；当前发送的SSB的索引号信息。可选的，通过预配置的方式，配置终端在一个同步周期内实际发送的SSB的数量信息和所述SSB的时域位置信息中的至少一项，并且通过PBCH对应的解调导频参考信号DMRS配置当前发送的SSB的索引号信息。
本公开的该实施例，在波束扫描或波束重复的情况下，可以确定终端发送的SSB的数量、所述SSB的时域位置及索引号等信息，可以使用较小的载荷，完成实际发送的SSB的数量、所述SSB的时域位置及索引号信息的广播，既降低了信令开销，又使得终端根据接收到的SSB的相关信息可以完成同步过程。
NR PBCH中的一些内容由于不适用于V2X，所以不用出现在V2X PSBCH中，比如NR PBCH中的频域信息pdcch-ConfigSIB1用来指示initial BWP(初始化的带宽部分)的时频域位置以及PDCCH监听时机，该字段可以在V2X PSBCH中省略，用来传输V2X的终端发送的SSB的数量、所述SSB的时域位置及索引号等信息。
进一步的，所述终端在一个周期内发送的SSB的最大数量与SSB的子载波间隔SCS相关，即采用预配置的方法，根据直通链路子载波间隔(Sidelink SCS)确定一个周期内可以发送的SSB的最大数量，如下表所示：
Figure PCTCN2020115874-appb-000001
该实施例所述的方法的优点是简单直接，不占用空口或Sidelink信令，开销小。
第二实施例：
一种信号的发送方法，应用于终端，所述方法包括：
在同步子帧或者时隙中，发送同步信号块SSB；所述SSB包括主同步信号PSS、辅同步信号SSS与物理广播信道PBCH；通过预配置的方式、所述PBCH、所述PBCH对应的解调导频参考信号DMRS和SSS中的至少一项，配置如下信息中的至少一项：终端在一个同步周期内实际发送的SSB的数量信息；所述SSB的时域位置信息；当前发送的SSB的索引号信息。
此时可以使用至少2个比特表示终端在一个同步周期内实际发送的SSB的数量和/或所述SSB的时域位置信息；所述终端在一个同步周期内实际发送的SSB在配置的同步子帧或时隙中是不连续的或者连续的。
例如，使用2个比特表示终端在一个周期内实际发送的SSB的数量和/或时域位置信息，由于只有2个比特，所以最多可以表示2个SSB的发送位置。此时终端在一个周期内实际发送的SSB可以在配置的同步子帧或时隙中是不连续发送的，例如采用bitmap(位图)的方式来映射SSB的时域位置。
同步子帧或时隙的配置方法可以是：每隔N个子帧或时隙设置连续M个同步子帧或时隙，SSB在同步子帧或时隙中发送，所述连续M个同步子帧或时隙为一组同步资源，N≥1，M≥1；同步子帧或时隙的间隔固定为N个子帧或时隙，在实际需要发送的SSB个数比较多的情况下，即降低了直通链路的业务时延，又降低了同步子帧或时隙配置的复杂度与信令开销。
为了避免直通链路通信(UE与UE之间的通信)对正常的空口通信(基站与UE之间的通信)的干扰，只有上行子帧或时隙是直通链路可以使用的。同步子帧或时隙的配置方法还可以是：每隔N个直通链路可用子帧或时隙设置连续M个同步子帧或时隙，SSB在同步子帧或时隙中发送，所述连续M个同步子帧或时隙为一组同步资源，N≥1，M≥1。
这里的N和/或M的数值，根据所述SSB的子载波间隔SCS确定。
bitmap的映射方法如下表所示：下表中每个方格表示一个同步子帧或者时隙Slot，SSB只能在同步子帧或者时隙中发送。X表示在该同步子帧或者 时隙中不发送SSB，O表示在该同步子帧或者时隙中发送SSB。
Figure PCTCN2020115874-appb-000002
该实施例使用2比特来通知一个周期内实际发送的SSB的数量与时域位置信息，信令开销比较小。
第三实施例：
一种信号的发送方法，应用于终端，所述方法包括：
在同步子帧或者时隙中，发送同步信号块SSB；所述SSB包括主同步信号PSS、辅同步信号SSS与物理广播信道PBCH；通过预配置的方式、所述 PBCH、所述PBCH对应的解调导频参考信号DMRS和SSS中的至少一项，配置如下信息中的至少一项：终端在一个同步周期内实际发送的SSB的数量信息；所述SSB的时域位置信息；当前发送的SSB的索引号信息。
此时可以使用至少2个比特表示终端在一个同步周期内实际发送的SSB的数量和/或所述SSB的时域位置信息；所述终端在一个同步周期内实际发送的SSB在配置的同步子帧或时隙中是不连续的或者连续的。
例如，使用4个比特表示终端在一个周期内实际发送的SSB的数量和/或时域位置信息，由于有4个比特，所以最多可以表示4个SSB的发送位置。此时终端在一个周期内实际发送的SSB可以在配置的同步子帧或时隙中是不连续发送的，例如采用bitmap的方式来映射SSB的时域位置。
同步子帧或时隙的配置方法可以是：每隔N个子帧或时隙设置连续M个同步子帧或时隙，SSB在同步子帧或时隙中发送，所述连续M个同步子帧或时隙为一组同步资源，N≥1，M≥1；同步子帧或时隙的间隔固定为N个子帧或时隙，在实际需要发送的SSB个数比较多的情况下，即降低了直通链路的业务时延，又降低了同步子帧或时隙配置的复杂度与信令开销。
为了避免直通链路通信(UE与UE之间的通信)对正常的空口通信(基站与UE之间的通信)的干扰，只有上行子帧或时隙是直通链路可以使用的。同步子帧或时隙的配置方法还可以是：每隔N个直通链路可用子帧或时隙设置连续M个同步子帧或时隙，SSB在同步子帧或时隙中发送，所述连续M个同步子帧或时隙为一组同步资源，N≥1，M≥1。
这里的N和/或M的数值，根据所述SSB的子载波间隔SCS确定。
所述的bitmap的映射方法如下表所示：下表中每个方格表示一个同步子帧或者时隙，SSB只能在同步子帧或者时隙中发送。X表示在该同步子帧或者时隙中不发送SSB，O表示在该同步子帧或者时隙中发送SSB。
