Description

无线通信方法、第一设备和第二设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及无线通信方法、第一设备和第二设备。
背景技术
当侧行通信工作在非授权频段时,某些地区法规规定终端设备发送的任何侧行信号在频域上均需要占据X%以上的信道带宽,例如X=80,否则,工作在相同非授权频段上的终端设备将有可能在已被占用的时频资源上进行信道监听,并认为该已被占用的时频资源符合资源选择条件,最终将导致多个终端设备在相同的时频资源上发送信号,造成严重的相互干扰,也需要考虑基于身份的加密(identity-based encryption,IBE)影响。
另外,为了避免在某几个物理资源块(physical resource block,PRB)上的发送功率过大,某些地区的法规限定了终端设备在每MHz上的最大发送功率,基于此,为了提高终端设备的发送功率,终端设备需要将发送带宽尽可能扩大。
截止目前,由于物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)和物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)在频域上仅占用连续多个PRB,这种设计方式无法保证占用的频域带宽总是大于信道带宽的X%,也无法保证发送功率的需求,所以无法应用于非授权频段上的侧行通信。

针对侧行通信,可以根据进行通信的终端所处的网络覆盖情况,将侧行通信分为网络覆盖内侧行通信,部分网络覆盖侧行通信及网络覆盖外侧行通信。
图1至图5是本申请提供的车载终端到车载终端的系统框架。
如图1所示,在网络覆盖内侧行通信中,所有进行侧行通信的终端(包括终端1和终端2)均处于同一网络设备的覆盖范围内,从而,所有终端均可以通过接收网络设备的配置信令,基于相同的侧行配置进行侧行通信。
如图2所示,在部分网络覆盖侧行通信情况下,部分进行侧行通信的终端位于网络设备的覆盖范围内,这部分终端(即终端1)能够接收到网络设备的配置信令,而且根据网络设备的配置进行侧行通信。而位于网络覆盖范围外的终端(即终端2),无法接收网络设备的配置信令,在这种情况下,网络覆盖范围外的终端将根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端发送的侧行广播信道PSBCH中携带的信息确定侧行配置,进行侧行通信。
对于网络覆盖外侧行通信,可分为无中央控制节点侧行通信和有中央控制节点的侧行通信。
如图3所示,对于无中央控制节点侧行通信,所有进行侧行通信的终端(包括终端1和终端2)均位于网络覆盖范围外,所有终端均根据预配置信息确定侧行配置进行侧行通信。
如图4所示,对于有中央控制节点的侧行通信,多个终端(包括终端1、终端2以及终端3)构成一个通信组,所述通信组内具有中央控制节点,又可以成为组头终端(Cluster Header,CH),所述中央控制节点具有以下功能之一:负责通信组的建立;组成员的加入、离开;进行资源协调,为其他终端分配侧行传输资源,接收其他终端的侧行反馈信息;与其他通信组进行资源协调等功能。例如,图4所示的终端1为终端1、终端2以及终端3所构成的通信组中的中央控制节点。下文中将CH到CM之间的传输称为HM链路,将CM到CH之间的传输称为MH链路。
设备到设备通信是基于D2D的一种侧行链路(Sidelink,SL)传输技术,与传统的蜂窝系统中通信数据通过网络设备接收或者发送的方式不同,因此具有更高的频谱效率以及更低的传输时延。车联网系统采用终端到终端直接通信的方式,在3GPP定义了两种传输模式:第一模式和第二模式。
第一模式:
终端的传输资源是由网络设备分配的,终端根据网络设备分配的资源在侧行链路上进行数据的发送;网络设备可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。如图1中,终端位于网络覆盖范围内,网络为终端分配侧行传输使用的传输资源。
第二模式:
终端在资源池中选取一个资源进行数据的传输。如图3中,终端位于小区覆盖范围外,终端在预配置的资源池中自主选取传输资源进行侧行传输;或者在图1中,终端在网络配置的资源池中自主选取传输资源进行侧行传输。
第二模式资源选择按照以下两个步骤进行:
步骤1:
终端将资源选择窗内所有的可用资源作为资源集合A。
如果终端在侦听窗内某些时隙发送数据,没有进行侦听,则这些时隙在选择窗内对应的时隙上的全部资源被排除掉。终端利用所用资源池配置中的“resource reservation period”域的取值集合确定选择窗内对应的时隙。
如果终端在侦听窗内侦听到PSCCH,测量该PSCCH的RSRP或者该PSCCH调度的PSSCH的RSRP,如果测量的RSRP大于SL-RSRP阈值,并且根据该PSCCH中传输的侧行控制信息中的资源预留信息确定其预留的资源在资源选择窗内,则从集合A中排除对应资源。如果资源集合A中剩余资源不足资源集合A进行资源排除前全部资源的X%,则将SL-RSRP阈值抬升3dB,重新执行步骤1。上述X可能的取值为{20,35,50},终端根据待发送数据的优先级从该取值集合中确定参数X。同时,上述SL-RSRP阈值与终端侦听到的PSCCH中携带的优先级以及终端待发送数据的优先级有关。终端设备将集合A中部分资源排除后的剩余资源作为候选资源集合。
步骤2:
终端从候选资源集合中随机选择若干资源,作为其初次传输以及重传的发送资源。
在NR-V2X中,需要支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在LTE-V2X中,支持广播传输方式,在NR-V2X中,引入了单播和组播的传输方式。
对于单播传输,其接收端终端只有一个终端。图5是本申请提供的单播传输的示意图。如图5所示,终端1、终端2之间进行单播传输。
对于组播传输,其接收端是一个通信组内的所有终端,或者是在一定传输距离内的所有终端。图6是本申请提供的组播传输的示意图。如图6所示,终端1、终端2、终端3和终端4构成一个通信组,其中终端1发送数据,该组内的其他终端设备都是接收端终端。
对于广播传输方式,其接收端是发送端终端周围的任意一个终端。图7是本申请提供的广播传输的示意图。如图7所示,终端1是发送端终端,其周围的其他终端,第终端2-终端6都是接收端终端。
为了便于理解本申请的技术方案,下面对NR V2X中PSCCH和PSSCH复用方式进行说明。
图8是本申请实施例提供的NR V2X中的PSCCH和PSSCH的4种复用方式的示意图。下面结合体8对NR V2X中可以采用的四种PSCCH和PSSCH的复用方式进行说明。
方式1A:
如图8所示,在这种方式中,PSCCH和PSSCH在时域上占用不重叠的OFDM符号,在频域上占用相同的PRB,即两者之间完全通过时分的方式复用。这种方式有利于降低PSSCH的解码时延,因为PSCCH可以在PSSCH开始之前便开始解码。然而,由于PSCCH和PSSCH在频域上占用的PRB个数相同,PSCCH在频域占用的PRB个数将随着PSSCH占用的PRB个数而改变,由于在NR-V2X中,业务负载和码率均可能在很大的范围内发生变化,从而导致PSSCH占用PRB个数的动态范围可能很大,而且PSSCH可以从任何一个子信道开始,所以,接收UE需要在每一个子信道起点盲检PSCCH。
方式1B:
如图8所示,方式1B和方式1A类似,PSCCH和PSSCH依然占用不重叠的OFDM符号,所以在时延方面,方式1B和方式1A的性能相同。但不同于方式1A的是,方式1B中PSCCH占用的PRB个数不随PSSCH的频域大小而变化,所以可以避免接收UE进行PSCCH盲检。但是,由于PSSCH占用的PRB个数往往多余PSCCH,在这种情况下将导致PSCCH所在OFDM符号上资源的浪费。
方式2:
如图8所示,方式2和LTE-V2X中采用的PSCCH和PSSCH的复用方式相同,即PSCCH和PSSCH占用不重叠的频域资源,但占用相同的OFDM符号。这种方式下,PSCCH占用整个时隙内的所有OFDM符号,所以可以采用类似于LTE-V2X中的方式,将PSCCH的功率谱密度相对于PSSCH增加3dB,从而增加PSCCH的可靠性。然而,在这种方式中接收UE需要在一个时隙结束后才能开始解码PSCCH,最终导致PSSCH的解码时延高于方式1A和方式1B。
方式3:
如图8所示,在这种方式中,PSCCH和一部分PSSCH在相同的OFDM符号上不重叠的频域资源上发送,而和其他部分PSSCH在不重叠的OFDM符号。方式3具备方式1A和方式1B低时延的优点, 但由于PSCCH的频域大小恒定,所以可以避免PSCCH盲检,此外,在PSCCH所在的OFDM符号上,如果PSCCH占用的PRB个数小于PSSCH,则剩余的PRB依然可以用于PSSCH发送,所以可以避免方式1A中资源浪费的问题。
下面结合图9和图10对NR-V2X中的时隙结构进行说明。
图9是本申请实施例提供的不包括PSFCH信道的时隙结构的示例;图10是本申请实施例提供的包括PSFCH信道的时隙结构的示例。
如图9或图10所示,在一个时隙内,第一个OFDM符号固定用于自动增益控制(Automatic Gain Control,AGC),在AGC符号上,UE复制第二个符号上发送的信息。而最后一个符号留有一个符号的保护间隔,用于UE从发送/接收状态转换到接收/发送状态。PSCCH和PSSCH通过上述方式3进行复用,PSCCH可以占用两个或三个OFDM符号,在频域上,如果PSCCH占用的PRB个数小于PSSCH,则在PSCCH所在的OFDM符号上,PSCCH可以和PSSCH频分复用。
换言之,在一个时隙内,PSCCH在时域上从该时隙的第二个侧行符号开始,占用2个或3个OFDM符号,在频域上可以占用{10,12 15,20,25}个PRB。为了降低UE对PSCCH的盲检测的复杂度,在一个资源池内只允许配置一个PSCCH符号个数和PRB个数。另外,因为子信道为NR-V2X中PSSCH资源分配的最小粒度,PSCCH占用的PRB个数必须小于或等于资源池内一个子信道中包含的PRB个数,以免对PSSCH资源选择或分配造成额外的限制。PSSCH在时域上也是从该时隙的第二个侧行符号开始,该时隙中的最后一个时域符号为保护间隔(GP)符号,其余符号映射PSSCH。该时隙中的第一个侧行符号是第二个侧行符号的重复,通常接收端终端将第一个侧行符号用作AGC(自动增益控制,Automatic Gain Control)符号,该符号上的数据通常不用于数据解调。PSSCH在频域上占据K个子信道,每个子信道包括N个连续的PRB。
在NR-V2X中,PSFCH资源是周期性配置的,如果在一个时隙内存在PSFCH资源,则PSFCH位于时隙内的倒数第二个OFDM符号,由于在PSFCH所在的OFDM符号上UE的接收功率可能发生变化,所在时隙内的倒数第三个符号也将用于PSFCH发送,以辅助接收UE进行AGC调整,此外,发送PSSCH的UE和发送PSFCH的UE可能不同,因此,在两个PSFCH符号之前,需要额外增加一个符号用于UE的收发转换。
如图9所示,时隙中可以不包括PSFCH信道。
如图10所示,当时隙中包含PSFCH信道时,该时隙中倒数第二个和倒数第三个符号用作PSFCH信道传输,在PSFCH信道之前的一个时域符号用作GP符号。
当侧行通信工作在非授权频段时,某些地区法规规定终端设备发送的任何侧行信号在频域上均需要占据X%以上的信道带宽,例如X=80,否则,工作在相同非授权频段上的终端设备将有可能在已被占用的时频资源上进行信道监听,并认为该已被占用的时频资源符合资源选择条件,最终将导致多个终端设备在相同的时频资源上发送信号,造成严重的相互干扰,也需要考虑基于身份的加密(identity-based encryption,IBE)影响。
另外,为了避免在某几个物理资源块(physical resource block,PRB)上的发送功率过大,某些地区的法规限定了终端设备在每MHz上的最大发送功率,基于此,为了提高终端设备的发送功率,终端设备需要将发送带宽尽可能扩大。
截止目前,由于物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)和物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)在频域上仅占用连续多个PRB,这种设计方式无法保证占用的频域带宽总是大于信道带宽的X%,也无法保证发送功率的需求,所以无法应用于非授权频段上的侧行通信。
基于此,本申请提供了一种无线通信方法、第一设备和第二设备,能够保证在非授权频段上,同一个发送端发送的PSCCH和PSSCH占用的信道带宽可以达到信道总带宽的一定比例,同时降低不同终端设备之间的干扰以及IBE影响。
图11示出了根据本申请实施例的无线通信方法100的示意性流程图,所述方法100可以由第一设备和第二设备交互执行。所述第一设备可以是用于发送物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)和物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)的发送端,所述第二终端设备可以是用于接收PSCCH和第一PSSCH。例如,所述第一设备或所述第二设备可以是上文涉及的终端B,所述第一设备或所述第二设备也可以是上文涉及的终端A。
如图11所示,所述方法100可包括以下部分或全部内容:
S110,发送第一PSCCH和第一PSSCH;
其中,所述第一PSCCH和所述第一PSSCH在频域上总共占用带宽大于或等于预设阈值的M1个交织资源;或所述第一PSCCH和所述第一PSSCH在信道占用时间COT内占用带宽大于或等于所述预 设阈值的C个子信道;M1和C均为正整数。
例如,所述第一PSCCH和所述第一PSSCH在频域上总共占用带宽大于或等于信道带宽的X%的M1个交织资源。所述信道带宽可以是一个信道的带宽。
基于以上技术方案,通过引入交织资源并将所述第一PSCCH和所述第一PSSCH在频域上总共占用带宽设计为大于或等于预设阈值的M1个交织资源,或在非授权频段引入子信道并将所述第一PSCCH和所述第一PSSCH在COT内占用带宽设计为大于或等于所述预设阈值的C个子信道,有利于同一个发送端在非授权频段上发送的PSCCH和PSSCH占用的信道带宽可以达到信道总带宽的一定比例,同时降低不同终端设备之间的干扰以及IBE影响。
需要说明的是,如果侧行通信工作在非授权频段上,一个时隙内可用于侧行发送的OFDM符号数可以由基站配置,CH配置,预配置,或者由标准定义,可以等于或小于一个时隙内的OFDM符号总数N,不失一般性,在接下来的描述中,均假设一个时隙内所有的OFDM符号均可以用于侧行发送,而且时隙内仅存在PSCCH和PSSCH以及两者的解调参考信号,当然,本申请中提出的方案依然可以用于一个时隙内可用于侧行发送的OFDM符号数小于N的情况,或时隙内存在其他信道或信号的情况,例如时隙内存在PSFCH的情况,本申请对此不作限定。根据以上分析,在非授权频段上,所述第一设备在发送第一PSCCH和第一PSSCH时,需要保证占用的带宽超过所述预设阈值,而有的情况下,需要尽可能扩大终端的发送带宽。
为便于对本申请提供的方案的理解,下面对本申请提供的所述M1个交织资源进行说明。

可选的,k的取值为网络设备配置的、组头终端配置的、预配置的或预定义的;和/或,k的取值是基于子载波间隔确定的。换言之,k的取值可以和子载波间隔(SCS)有关,即不同的子载波间隔对应不同的k的取值。
可选的,k=floor(W/m),或k=ceil(W*n);其中,W表示资源池内子信道的总数,m为正整数,n大于0且小于1,floor()表示向下取整,ceil()表示向上取整。例如,m可为0.8或其他数值。

需要说明的是,本申请中涉及的子信道可包括S个连续的PRB,S的取值为网络设备配置的、组头终端配置的、预配置的或预定义的。例如,S个连续的PRB包括但不限于10,12,15,20,25,50,75或100个连续的PRB。

可选的,所述第一区域内的PRB的索引的排列顺序和所述第三区域内的PRB的索引的排列顺序相同;和/或,所述第二区域内的子信道的索引的排列顺序和所述第一区域内的PRB的索引的排列顺序相反;和/或,所述第二区域内的子信道的索引的排列顺序和所述第三区域内的PRB的索引的排列顺序相反。
例如,所述第一区域内的PRB的索引的排列顺序和所述第三区域内的PRB的索引的排列顺序相同,所述第二区域内的子信道的索引的排列顺序和所述第一区域内的PRB的索引的排列顺序相反;所述第二区域内的子信道的索引的排列顺序和所述第三区域内的PRB的索引的排列顺序相反。作为一个示例,所述第一区域和所述第三区域内为PRB按降序确定索引,所述第二区域内的子信道按照升序确定索引,按照这样的方式,可以保证所述第二区域内的第一个子信道和所述第一区域内索引相同的PRB相邻,所述第二区域内的最后一个子信道和所述第三区域内索引相同的PRB相邻,进而有利于降低带内泄露干扰。
可选的,所述第二区域内的第一个子信道和所述第一区域内与所述第一个子信道的索引相同的PRB相邻;和/或,所述第二区域内的最后一个子信道和所述第三区域内与所述最后一个子信道的索引相同的PRB相邻。

在本实施例中,如果所述第一PSCCH和被调度的所述第一PSSCH在同一个时隙内发送,则在用于发送所述第一PSCCH的符号上和仅用于发送所述第一PSSCH的符号上,第一设备占用的频域资源相同,如果仅用于发送所述第一PSSCH的符号上所述第一设备占用S3个交织资源,则所述S3个交织资源在频域上应包括所述第一设备用于发送所述第一PSCCH的频域资源,在用于发送所述第一PSCCH的符号上,所述第一设备在所述S3个交织资源中未用于发送所述第一PSCCH的频域资源上发送所述第一PSSCH。本实施例允许所述第一PSCCH早于所述第一PSSCH发送,有利于接收端提前进行所述第一PSCCH解码,并根据所述第一PSCCH解码结果进行所述第一PSSCH解调,有利于降低所述第一PSSCH的解调时延。而且,本实施例中交织资源的主体以子信道为粒度,当不同交织资源用于不同终端时,可以降低不同交织资源之间的带内泄露干扰。此外,在所述第一PSCCH所在的OFDM符号上,如果所述第一PSCCH占用的PRB个数小于所述第一PSSCH,则剩余的PRB依然可以用于所述第一PSSCH发送,可以提升资源的利用率。
实施例4:
本实施例中,所述第一PSCCH和所述第一PSSCH在信道占用时间COT内占用带宽大于或等于所述预设阈值的C个子信道。可选的,C>1,所述C个子信道是连续的。
如果第一设备在其它终端,CH,或基站共享的COT内选择资源发送所述第一PSCCH和所述第一PSSCH,则所述第一设备选择连续的子信道发送所述第一PSCCH和所述第一PSSCH,例如,所述第一设备的发送带宽应不小于2MHz,即所述第一设备选择的用于发送所述第一PSCCH和所述第一PSSCH的频域资源不小于2MHz。
如果所述第一PSCCH和被调度的所述第一PSSCH在同一个时隙内发送,则在用于发送所述第一PSCCH的符号上和仅用于发送所述第一PSSCH的符号上,所述第一设备占用的频域资源相同,如果仅用于发送所述第一PSSCH的符号上,所述第一设备占用S4个交织资源,则所述S4个交织资源在频域上应包括用于发送所述第一PSCCH的频域资源,在用于发送所述第一PSCCH的符号上,所述S4个交织资源中未用于发送所述第一PSCCH的频域资源可用于发送所述第一PSSCH。在用于发送所述第一PSCCH的符号上,所述第一PSCCH占用一个子信道内的M4个PRB。
本实施例中,考虑到在COT内所述第一设备发送数据没有最小占用带宽的要求,因此所述第一设 备可以选择连续的频域资源发送所述第一PSCCH和所述第一PSSCH,以降低不同终端设备之间的干扰以及IBE影响。
基于以上方案可知,本申请提出了一种第一PSCCH和第一PSSCH的发送方法,作为一个示例,一方面,本申请通过引入以子信道为粒度或包括第一区域、第二区域以及第三区域的资源池,并通过设计所述第一PSCCH和所述第一PSSCH的复用方式,有利于同一个发送端在非授权频段上发送的PSCCH和PSSCH占用的信道带宽可以达到信道总带宽的一定比例,同时降低不同终端设备之间的干扰以及IBE影响。例如,所述第一PSCCH和所述第一PSSCH可以占用不同的OFDM符号,而且在不同的OFDM符号上占用不同的交织资源;再如,所述第一PSCCH和所述第一PSSCH占用相同的OFDM符号,在频域上占用不同的交织资源;再如,所述第一PSCCH和所述第一PSSCH在一个时隙的部分OFDM符号上通过频分的方式复用,即在上述部分OFDM符号上,所述第一PSCCH和所述第一PSSCH可以占用不同的交织资源或相同交织资源的不同PRB。作为另一个示例,当第一设备在COT内发送所述第一PSCCH和所述第一PSSCH时,将其占用的频域资源设计为连续的子信道,同样有利于同一个发送端在非授权频段上发送的PSCCH和PSSCH占用的信道带宽可以达到信道总带宽的一定比例,同时降低不同终端设备之间的干扰以及IBE影响。
