- the two terminals that need to communicate first need to establish synchronization on the PC5 port (Sidelink).
- the method of establishing synchronization is that one terminal A sends synchronization and broadcast signals, and the other terminal B receives the synchronization and broadcast signals sent by terminal A. Once terminal B receives and demodulates successfully, the two terminals can establish synchronization. Communication is ready.

相关申请的交叉引用
本申请主张在2019年11月8日在中国提交的中国专利申请号No.201911086762.7的优先权,其全部内容通过引用包含于此。
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、装置及终端。
在第五代(5
th generation,5G)新无线(NR Radio,NR)车联网(vehicle to everything,V2X)***中,终端与终端之间使用PC5口(Sidelink)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同步信号块(Synchronization Signal Block,SSB)携带的。每个Slot(时隙)中携带2个SSB块,并且主同步信号(Primary Synchronization Signal,PSS)与辅同步信号(Secondary Synchronization Signal,SSS)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。
在相关技术中的长期演进(Long Term Evolution,LTE)V2X技术中, Sidelink直通链路上每160ms最多配置3个同步子帧,用户设备或者终端(User Equipment,UE)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。
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。5G NR支持更大的带宽、灵活的子载波间隔的配置、同步信号与广播信息以SSB波束扫描或波束重复的形式发送。这就给NR V2X物理层结构的设计带来了新的挑战,原来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,需要重新进行设计,需要引入SSB波束扫描或波束重复的机制,以满足NR V2X的需求。
而NR V2X中引入了SSB波束扫描或波束重复的机制之后,就会导致在一个同步周期中发送多个同步信号块,最多在一个同步周期内需要发送或接收64个同步信号块。如果配置连续的同步资源将这64个同步信号块连续发送出去,就会导致较高的时延,不利于实时V2X业务数据的传输。

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,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:
步骤11,在一个同步周期内发送P个同步信号块SSB,所述P个SSB分为Q个组,任意一个组内包括至少一个SSB,P和Q均是大于或等于1的正整数,当一个同步周期内包括至少两个SSB时,至少有一个SSB的时域位置是预配置的或通过物理广播信道(Physical Broadcast Channel,PBCH)携带。
该实施例中,可选的,所述SSB可以是直通链路同步信号块(Sidelink-Synchronization Signal Block,S-SSB),所述PBCH是物理直通链路广播信道(Physical Sidelink Broadcast Channel,PSBCH),所述同步周期是直通链路同步周期。可选的,所述P可以是预配置的,所述Q可以是预配置的。这里的每个组是一个突发(burst);一个同步周期内发送的所有S-SSB组成突发集(burst set)。
该实施例通过预配置的方法和/或通过物理广播信道携带的方法,将同步信号块SSB集合的时域位置配置信息通知给终端,以便终端在所述时域位置中接收同步信号块SSB集合并以软合并的方式获取同步信息。使用该方法,既使得终端能够在预先设定的时域位置检测同步信号块集合,提升了同步信号块的检测成功率,同时不连续发送的同步信号块集合又避免引入较高的业务时延,从而提升了直通通信链路的同步成功率,并降低了传输时延。
该实施例的具体实现方法如下:在一个同步周期内发送P(P大于或等于1)个S-SSB,P个S-SSB分成Q(Q大于或等于1)个组,任意一个组内部包括有至少一个S-SSB。当一个同步周期内包括至少两个S-SSB时,至少有一个S-SSB的时域位置是预配置的,或者,根据PSBCH所携带的信息确定的。这里,至少有一个S-SSB的时域位置的配置信息可以包括:同一个组内的两个相邻的S-SSB的时间间隔Ti。所述时间间隔是指两个S-SSB之间间隔的时隙个数或绝对时长;并且同一个组内不同的S-SSB之间的时间间隔可以相同,也可以不同。可选的,所述时隙为以下一项:物理时隙;空口时隙; 上行时隙;直通链路时隙。
如图2所示,为120KHz子载波间隔下的S-SSB集合发送时域位置示意图。由于是120KHz,一个子帧内包含有8个时隙,每一个小竖格代表一个时隙。空白的小竖格代表不包含S-SSB的时隙,有线条的小竖格代表包含S-SSB的时隙。1个S-SSB集合包括有16个S-SSB,分成4个组,每组4个S-SSB。这里预配置的方法是配置同一个组内的两个相邻的S-SSB的时间间隔Ti。
对于第一组S-SSB,由于有4个S-SSB,所以需要配置3个时间间隔T1,T2,T3。时间间隔的计算方法不同,会导致时间间隔的数值有所不同。从图2可以看出,如果时间间隔的计算方法是从第一个S-SSB的终点到第二个S-SSB的起点,那么T1为1个时隙;如果时间间隔的计算方法是从第一个S-SSB的起点到第二个S-SSB的起点,那么T1为2个时隙。同理,T2为2个时隙或3个时隙,T3为3个时隙或4个时隙。对于第二组S-SSB,由于有4个S-SSB,所以需要配置3个时间间隔T4,T5,T6。T4为3个时隙或4个时隙;T5为1个时隙或2个时隙;T6为3个时隙或4个时隙。对于第三组S-SSB和第四组S-SSB的时间间隔配置,也是类似的,此处不再赘述。该实施例配置直观,易于计算,并且每个S-SSB的时间间隔都是独立配置的,灵活可变。
本公开的一可选的实施例中,当所述Q大于或者等于2时,相邻两个组之间的时间间隔是预配置的,所述相邻两个组之间的时间间隔的单位为时隙或毫秒,当时间间隔的单位为时隙时,时间间隔的数值为大于或等于1个时隙,当时间间隔的单位为毫秒时,时间间隔的数值为大于或等于0毫秒。可选的,相邻两个组之间的时间间隔相同。可选的,所述时隙为以下一项:物理时隙;空口时隙;上行时隙;直通链路时隙。
该实施例的具体实现方法如下:在一个同步周期内发送P(P大于或等于1)个S-SSB,P个S-SSB分成Q(Q大于或等于1)个组,任意一个组内部包括有至少一个S-SSB。当一个同步周期内包括至少两个S-SSB时,至少有一个S-SSB的时域位置是预配置的,或者,根据PSBCH所携带的信息确定的。两个组之间的时间间隔Mi也是预配置的。
如图2所示,为120KHz子载波间隔下的S-SSB集合发送时域位置示意图。由于是120KHz,一个子帧内包含有8个时隙,当然,一个子帧也可以包 括其它数量的时隙,每一个小竖格代表一个时隙。空白的小竖格代表不包含S-SSB的时隙,有线条的小竖格代表包含S-SSB的时隙。这里以1个S-SSB集合包括有16个S-SSB为例,S-SSB集合分成4个组,每组4个S-SSB。两个组之间的时间间隔Mi也是预配置的。
对于第一组S-SSB和第二组S-SSB之间的时间间隔M1,如果时间间隔的计算方法是从第一组最后一个S-SSB的终点到第二组第一个S-SSB的起点,那么M1为6个时隙;如果时间间隔的计算方法是从第一组第一个S-SSB的起点到第二组第一个S-SSB的起点,那么M1为16个时隙。对于第二组S-SSB和第二组S-SSB之间的时间间隔M2,按照两种不同的计算方法,M2为5个时隙或16个时隙。对于第三组S-SSB和第四组S-SSB的之间时间间隔配置M3,也是类似的,此处不再赘述。
特别的,相邻两个组之间的时间间隔可以是相同的,即M1、M2及M3相等。这样可以简化配置,降低配置的复杂度。当相邻两个组之间的时间间隔是相同的数值时,仅需要配置一个数值M0即可,即M1=M2=M3=M0。
这种配置方法的优点是配置直观,易于计算,并且每两个S-SSB组之间的时间间隔可以是独立配置的,也可以配置成相同的数值,配置灵活可变。
本公开的一可选的实施例中,至少有一个SSB的时域位置是预配置时,所述时域位置的预配置信息包括以下参数中的至少一项:同一个组内的相邻两个SSB之间的时间间隔;同一个组内所有SSB相对于组内第一个SSB的时间间隔;所有SSB相对于一个同步周期内第一个SSB的时间间隔;其中,所述时间间隔为Ti个时隙或Ti毫秒,Ti大于或等于0。可选的,所述时隙为以下一项:物理时隙;空口时隙;上行时隙;直通链路时隙。
这里,同一个组内所有SSB相对于组内第一个SSB的时间间隔的实施例具体实现方法如下:在一个同步周期内发送P(P大于或等于1)个S-SSB,P个S-SSB分成Q(Q大于或等于1)个组,任意一个组内部包括有至少一个S-SSB。当一个同步周期内包括至少两个S-SSB时,至少有一个S-SSB的时域位置是预配置的,或根据PSBCH所携带的信息确定的。所述至少有一个S-SSB的时域位置是预配置的,预配置的方法是配置同一个组内所有S-SSB相对于组内第一个S-SSB的时间间隔Ti。
如图2所示,为120KHz子载波间隔下的S-SSB集合发送时域位置示意图。由于是120KHz,一个子帧内包含有8个时隙,当然,一个子帧也可以包括其它数量的时隙,每一个小竖格代表一个时隙。空白的小竖格代表不包含S-SSB的时隙,有线条的小竖格代表包含S-SSB的时隙。这里以1个S-SSB集合包括有16个S-SSB为例进行说明,S-SSB集合分成4个组,每组4个S-SSB。这里预配置的方法是配置同一个组内所有S-SSB相对于组内第一个S-SSB的时间间隔Ti。
对于第一组S-SSB,由于有4个S-SSB,所以需要配置3个时间间隔T1,T2,T3。时间间隔的计算方法不同,会导致时间间隔的数值有所不同。从图2可以看出,如果时间间隔的计算方法是从第一个S-SSB的终点到第二个S-SSB的起点,那么T1为1个时隙;如果时间间隔的计算方法是从第一个S-SSB的起点到第二个S-SSB的起点,那么T1为2个时隙。同理,T2为4个时隙或5个时隙,T3为8个时隙或9个时隙。对于第二组S-SSB,由于有4个S-SSB,所以需要配置3个时间间隔T4,T5,T6。T4为3个时隙或4个时隙;T5为5个时隙或6个时隙;T6为9个时隙或10个时隙。对于第三组S-SSB和第四组S-SSB的时间间隔配置,也是类似的,此处不再赘述。该实施例的配置方法的优点是配置直观,易于计算,并且每个S-SSB的时间间隔都是独立配置的,灵活可变。
这里,所有SSB相对于一个同步周期内第一个SSB的时间间隔的实施例具体实现方法如下:
在一个同步周期内发送P(P大于或等于1)个S-SSB,P个S-SSB分成Q(Q大于或等于1)个组,任意一个组内部包括有至少一个S-SSB。当一个同步周期内包括至少两个S-SSB时,至少有一个S-SSB的时域位置是预配置的,或根据PSBCH所携带的信息确定的。所述至少有一个S-SSB的时域位置是预配置的,预配置的方法是配置所有S-SSB相对于一个同步周期内第一个S-SSB的时间间隔Ti。
如图2所示,为120KHz子载波间隔下的S-SSB集合发送时域位置示意图。由于是120KHz,一个子帧内包含有8个时隙,当然,一个子帧也可以包括其它数量的时隙,每一个小竖格代表一个时隙。空白的小竖格代表不包含 S-SSB的时隙,有线条的小竖格代表包含S-SSB的时隙。这里以1个S-SSB集合包括有16个S-SSB为例进行说明,S-SSB集合分成4个组,每组4个S-SSB。这里预配置的方法是配置所有S-SSB相对于一个同步周期内第一个S-SSB的时间间隔Ti。
对于第一组S-SSB,由于有4个S-SSB,所以需要配置3个时间间隔T1,T2,T3。时间间隔的计算方法不同,会导致时间间隔的数值有所不同。从图2可以看出,如果时间间隔的计算方法是从第一个S-SSB的终点到第二个S-SSB的起点,那么T1为1个时隙;如果时间间隔的计算方法是从第一个S-SSB的起点到第二个S-SSB的起点,那么T1为2个时隙。同理,T2为4个时隙或5个时隙,T3为8个时隙或9个时隙。对于第二组S-SSB,由于有4个S-SSB,所以需要配置3个时间间隔T4,T5,T6。T4为15个时隙或16个时隙;T5为12个时隙或13个时隙;T6为16个时隙或17个时隙。对于第三组S-SSB和第四组S-SSB的时间间隔配置,也是类似的,此处不再赘述。该实施例的配置方法的优点是配置直观,易于计算,并且每个S-SSB的时间间隔都是独立配置的,灵活可变。
这里,同一个组内的相邻两个SSB的时间间隔相同的实施例具体实现方法如下:
在一个同步周期内发送P(P大于或等于1)个S-SSB,P个S-SSB分成Q(Q大于或等于1)个组,任意一个组内部包括有至少一个S-SSB。当一个同步周期内包括至少两个S-SSB时,至少有一个S-SSB的时域位置是预配置的,或根据PSBCH所携带的信息确定的。所述至少有一个S-SSB的时域位置是预配置的,预配置的方法是配置同一个组内的两个相邻的S-SSB的时间间隔,并且同一个组内的多个SSB的时间间隔都是相同的T0个时隙或T0毫秒。
如图3所示,为120KHz子载波间隔下的S-SSB集合发送时域位置示意图。由于是120KHz,一个子帧内包含有8个时隙,当然,一个子帧也可以包括其它数量的时隙,每一个小竖格代表一个时隙。空白的小竖格代表不包含S-SSB的时隙,有线条的小竖格代表包含S-SSB的时隙。这里以1个S-SSB集合包括有16个S-SSB为例进行说明,S-SSB集合分成4个组,每组4个 S-SSB,。这里预配置的方法是配置同一个组内的两个相邻的S-SSB的时间间隔T0。
对于第一组S-SSB,由于有4个S-SSB并且组内的S-SSB的时间间隔相同,所以只需要配置1个时间间隔T0。时间间隔的计算方法不同,会导致时间间隔的数值有所不同。从图3可以看出,如果时间间隔的计算方法是从第一个S-SSB的终点到第二个S-SSB的起点,那么T0为1个时隙;如果时间间隔的计算方法是从第一个S-SSB的起点到第二个S-SSB的起点,那么T0为2个时隙。对于第二组S-SSB,T0同样也是1个时隙或2个时隙。对于第三组S-SSB和第四组S-SSB的时间间隔配置,也是类似的,此处不再赘述。该实施例的优点是配置直观,易于计算,并且由于同一个组内相邻S-SSB的时间间隔都是相同的,只需要配置少量的参数,配置比较简单。
本公开的一可选的实施例中,每个组内包含的SSB的数量是预配置的,可选的,每个组内包含的SSB的数量相同,具体实现方法如下:
在一个同步周期内发送P(P大于或等于1)个S-SSB,P个S-SSB分成Q(Q大于或等于1)个组,任意一个组内部包括有至少一个S-SSB。当一个同步周期内包括至少两个S-SSB时,至少有一个S-SSB的时域位置是预配置的,或根据PSBCH所携带的信息确定的。每个组内包含的S-SSB的数量Ni也是预配置的。
如图2所示,为120KHz子载波间隔下的S-SSB集合发送时域位置示意图。由于是120KHz,一个子帧内包含有8个时隙,当然,一个子帧也可以包括其它数量的时隙,每一个小竖格代表一个时隙。空白的小竖格代表不包含S-SSB的时隙,有线条的小竖格代表包含S-SSB的时隙。这里以1个S-SSB集合包括有16个S-SSB为例进行说明,S-SSB集合分成4个组,每组4个S-SSB。每个组内包含的S-SSB的数量Ni也是预配置的。
对于第一组S-SSB包含的S-SSB数量N1,从图2可以看出N1等于4。
对于第二组S-SSB包含的S-SSB数量N2,从图2可以看出N2等于4。
对于第三组S-SSB包含的S-SSB数量N3,从图2可以看出N3等于4。
对于第三组S-SSB包含的S-SSB数量N4,从图2可以看出N4等于4。
需要指出的是,图2中4个组所包含的S-SSB的数量都是相同的,即N1、 N2、N3及N4相等。但在实际配置中,N1、N2、N3及N4可以配置成不同的数值,以提高灵活性。当每个组内所包含的S-SSB数量相同时,仅需要配置一个数值N0即可,即N1=N2=N3=N4=N0。
该实施例的配置方法的优点是配置直观,易于计算,并且每个S-SSB组内所包含的S-SSB的数量可以是独立配置的,也可以配置成相同的数值,配置灵活可变。
本公开的一可选的实施例中,以下至少一个参数是根据终端使用的子载波间隔(Subcarrier Spacing,SCS)、频率范围和PBCH携带的信息中的至少一项确定的:

表2
通过PSBCH中的2个比特来指示的P如下表格组所示:
该实施例的配置方法的优点是P是通过PSBCH通知的,P的数值灵活可配置。并且在通知N0和T0时简单直接,不占用空口或Sidelink信令。
