Description

载波集合的确定方法、装置、存储介质及电子装置 技术领域
本公开涉及通信领域，具体而言，涉及一种载波集合的确定方法、装置、存储介质及电子装置。
背景技术
在边链路Sidelink通信系统中，UE之间使用Sidelink资源进行信息的传输，根据具体的应用场景及业务类型等，Sidelink通信方式包括设备到设备(Device to Device，简称为D2D)通信，车联网通信，包括车辆到车辆(Vehicle to Vehicle，简称为V2V)或车辆到其他设备(Vehicle to everything，简称为V2X)通信等。
对于Sidelink通信，例如车联网通信，为了规范各个地区的频谱使用管理和便于接收方选择正确的频谱接收感兴趣的业务，目前规定了各个V2X业务类型的一些配置参数，其中包括该业务能够使用的一个或多个频点(frequency)/载波(carrier)，业务所对应的接入层Destination ID(即，目的标识)等。当业务进入接入层进行传输时，接入层会在一个或多个逻辑信道传输该业务，这些逻辑信道上的数据包会有一个优先级PPPP(ProSe(Proximity Service)priority per packet，每个邻近服务数据包的优先级，简称PPPP)以及一个与业务所对应的Destination ID。
在边链路Sidelink通信系统中，用户设备(User Equipment，简称为UE)之间有业务需要传输时，UE之间的业务数据不经过网络侧的转发，而是直接由数据源UE通过Sidelink传输给目标UE，图1是根据相关技术的Sidelink通信结构的示意图。另外，根据通信资源的获得方法，Sidelink通信可以分为两大类通信模式，第一类模式中UE发送Sidelink信号的资源来自于基站的调度，而第二类模式中，UE在配置或者预配置的资源池(resource pool)中，根据资源选择策略，自主地选择资源的通信方式，资源选择策略主要包括：sensing(探测)机制，partial sensing(部分探测) 机制，random selection(随机选择)机制。
随着车联网，直连通信需求的增长，市场对Sidelink通信系统的要求也在不断提高，例如为了提高速率或提高可靠性，需要Sidelink通信系统可以支持载波聚合(Carrier Aggregation，简称为CA)，即使用多个载波进行并行传输，这里的并行可以是同时的也可以是分时的。然而，对于Sidelink使用CA通信，需要解决的问题是选择哪些载波进行通信。
目前随着Sidelink CA的讨论，一个新的载波选择的方法或过程需要确定，目前阶段，很多影响载波选择的因素被讨论到，包括载波的占用比例CBR(channel busy ratio)，要发送的数据的业务类型，数据优先级PPPP，UE的能力等，但是最终的载波选择过程是怎样的，在载波选择过程中上述因素怎样发生作用，目前没有一个完整的定义。
针对相关技术中用户设备UE进行边链路Sidelink传输时，缺少一个完整的波载波集合确定方法的问题，目前尚未提出有效的解决方案。

根据本公开的又一个实施例，还提供了一种电子装置，包括存储器和处理器，所述存储器中存储有计算机程序，所述处理器被设置为运行所述计算机程序以执行上述任一项方法实施例中的步骤。
通过本公开中的实施例，由于确定了一种逻辑信道组所对应的载波集合，应用于用户设备UE进行边链路Sidelink传输。因此，可以解决相关技术中用户设备UE进行边链路Sidelink传输时，缺少一个完整的波载波集合确定方法的问题，达到为用户设备UE确定进行边链路Sidelink传输时所需的载波集合的目的。

实施例2
在本实施例中提供了一种运行于上述移动终端的载波集合的确定方法，图3是根据本公开实施例的载波集合的确方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，确定用于用户设备UE进行边链路Sidelink传输的预定逻辑信道组所对应的第一载波集合；其中，所述预定逻辑信道组包括一个或多个逻辑信道，且所述预定逻辑信道组中的各逻辑信道对应相同的目的标识。
可选地，上述步骤的执行主体可以为终端等，上述的目的标识(可以称为Destination ID，后述类似，不再赘述)可以是ProSe Destination ID，也可以是layer 2 Destination ID，但不限于此。
在上述实施例中，确定了一种逻辑信道组所对应的载波集合，且该逻辑信道组中的各逻辑信道对应于相同的目的标识，因此，可以解决相关技术中用户设备UE进行边链路Sidelink传输时，缺少一个完整的波载波集合确定方法的问题，达到为用户设备UE确定进行边链路Sidelink传输时所需的载波集合的的目的。
在一个可选实施例中，确定用于用户设备UE进行边链路Sidelink传 输的预定逻辑信道组所对应的第一载波集合包括：确定所述UE进行所述Sidelink传输的第二载波集合；从所述第二载波集合中确定所述第一载波集合。在本实施例中，第一载波集合为第二载波集合的子集。

下面结合具体实施例来对如何确定第二载波集合进行说明：
具体实施例一
本实例用于说明确定(也可以称为配置)UE用于Sidelink传输的载波集合A(对应于本实施例中的第二载波集合)的方法。
载波集合为A为UE可能用做Sidelink CA传输的载波集合，如不特殊说明本具体实施例中的传输包括接收和发送。可选地，可以配置一个载波集合A，集合A里面的载波可能被用作Sidelink CA的发送，也可以被用作Sidelink CA的接收。UE在集合A里面的载波进行发送前的探测(sensing)、接收数据，发送数据等操作。载波集合A中的载波的选择跟多种因素有关，包括UE想要进行传输的业务类型(service type)，UE的传输能力(UE capabilities)，各个载波上信道占用比率(Channel Busy Ratio，简称为CBR)，各个载波上使用的同步参考/同步参考源(synchronization reference/synchronization reference source)或者各个载波的同步参考配置(也可称为同步配置)等因素，包括：载波的最优先同步参考(源)类型或同步参考优先级等。如图4所示。
其中，各个因素的作用如下：
(1)Service(对应于UE需要传输的业务类型)：每个service都对应一个其能够进行Sidelink传输的频点/载波(frequency/carrier)集合，无特殊说明本公开实施例中的载波一般等同于频点/载波(frequency/carrier)。若UE想要使用载波聚合传输一个业务，那么UE应当选择该业务对应的载波集合中的一个或多个载波。若UE同时进行多个业务的传输，那么UE应当从这多个业务所对应的多个载波集合中选择载波作为载波集合A中的载波。具体实现中，不同的业务具有不同的优先等级；同一个业务的不同的载波也可能有不同的优先等级，UE在选择载波时考虑这些优先等级进行载波选择。例如，可以优先选择高优先级业务的高优先级载波。
(2)UE capabilities(对应于UE的传输能力)：主要是UE的接收能力，在UE使用基于sensing(探测)的模式进行发送之前，UE要对载波进行sensing，UE能够同时进行sensing的载波数目受限于UE的接收能力，所以载波集合A中载波的个数不应超过UE的接收能力。可选的，也可以考虑UE的发送能力，包括根据UE能够同时发送的载波数目，能够同时进行发送的频段组合，是否能够在不连续的载波进行发送等因素确定载波集合A中载波。例如，UE可以同时发送的载波数目为2且不支持在两个频段上切换发送，接收能力为8且支持在两个频段上接收(这里假设一个频段包括4个载波)，此时可以将载波集合A设为某个频段上的4个载波，又或者按照发送能力为2为限制，将载波集合A的大小限制为不大于2。
(3)CBR(对应于载波上的信道占用比率)：备选的各个载波上，每个载波上的信道占用状况是不同的，为了避免拥塞，则UE应当选择CBR比较低的载波作为载波集合A中的载波，备选载波的CBR可以由UE测得(UE可以分时的对各个载波进行CBR测量，备选载波的数量可以大于UE的接收能力)，也可以从网络侧或者其他设备获得。
(4)Synchronization reference/synchronization reference source/synchronization configuration(同步参考或同步参考源或同步配置 (对应于上述的同步参考信息))：多载波传输，若多个载波的定时不对齐，即同步参考或同步参考源或同步配置不同时，会影响信道的使用效率，也会增加UE的复杂度。所以用于Sidelink载波聚合进行发送的载波使用相同的同步参考或同步参考源或同步配置；用于Sidelink载波聚合进行接收的载波使用相同的同步参考或同步参考源或同步配置。所以，一般的载波集合A中的载波应使用相同的同步参考或同步参考源或同步配置。又或者，载波集合A中的载波应具有相同的同步配置，同步配置包括载波的最优先同步参考(源)类型或同步参考优先级等。
在确定载波集合A时，需要满足以下原则至少之一：
1)UE从想要传输的多个业务所对应的多个载波集合中选择载波作为载波集合A中的载波(对应于UE需要传输的业务类型)。
2)UE Sidelink CA的载波集合A不超过UE的能力(对应于UE的传输能力)。
3)UE考虑各个载波的CBR。例如优先选择CBR低的载波(对应于载波上的信道占用比率)。
4)UE考虑各个载波的同步，用于Sidelink载波聚合进行传输的载波使用相同的同步参考或同步参考源，或具有相同的同步配置(对应于载波使用的同步参考信息)。
具体的确定载波集合A的确定方式为：
1)UE确定想要传输的多个业务所对应的多个载波集合，这些集合内的载波都是备选载波。
2)UE对备选载波进行排序，影响排序的因素包括：载波能够承载的业务类型，CBR，同步参考信息等因素。
3)在不超过UE能力的前提下，截取排序后的备选载波中排序靠前的载波作为载波集合A(对应于第二载波集合)。
具体实施例二
本实例用于说明另一种确定(或者说配置)UE用于Sidelink传输的载波集合A(对应于第二载波集合)的方法。
在本具体实施例中，配置的载波集合A包括一个可能被用作Sidelink CA接收的载波集合A1，以及一个可能被用作Sidelink CA发送的载波集合A2。一般的，A2为A1的子集。UE在集合A2里面的载波进行发送前的探测(sensing)、进行发送等操作；UE在集合A1里面的载波进行发送前的接收等操作，如图5所例示；同具体实例一类似，载波集合A(包括A1和A2)中的载波的选择跟多种因素有关，包括UE想要进行传输的业务类型(service type)，UE的传输能力(UE capabilities)，各个载波上信道占用比率(CBR)，各个载波上使用的同步参考/同步参考源等因素(synchronization reference/synchronization reference source)，具体的原则和过程与具体实例一中载波集合A的确定原则一致。
另外，适用于具体实施例一和具体实施例二，载波集合A可以由协议栈的高层确定，并配置给低层，可选地，可以由UE的协议栈的高层确定并通过内部接口配置给UE自己的低层，一般的由RRC(Radio Resource Control，无线资源控制)层确定并配置给低层，低层可以是MAC(media access control，媒体接入控制)层或PHY(physical，物理)层；载波集合A也可以由基站确定并通过信令配置给UE。
在一个可选的实施例中，从上述第二载波集合中确定上述第一载波集合包括：根据上述预定逻辑信道组所包含业务类型对应的载波集合确定上述预定逻辑信道组对应的第二备选载波集合；确定所述第二载波集合和所述第二备选载波集合的交集的子集为所述第一载波集合。在本实施例中，可以根据逻辑信道组所包含的业务类型确定该逻辑信道组所对应的载波集合C(对应于第二备选载波集合)，通过上述实施例中的载波集合A(对应于第二载波集合)与载波集合C取交集，进而得到的载波集合B(对应于第一载波集合)作为该逻辑信道组所对应的载波集合。
在一个可选实施例中，根据上述预定逻辑信道组所包含的业务类型对应的载波集合确定所述预定逻辑信道组对应的第二备选载波集合包括以下之一：当上述预定逻辑信道组对应的目的标识对应一个或多个业务类型，且该一个或多个业务类型对应的相同的载波集合时，确定上述第二备选载波集合为所述预定逻辑信道组所包含的任一业务类型对应的载波集合(或者为该集合的子集)；当所述预定逻辑信道组对应的目的标识对应多个业务类型，且所述预定逻辑信道组所包含的各业务类型的载波集合交集为非空集合时，确定所述第二备选载波集合为所述预定逻辑信道组所包含的各业务类型的载波集合的交集(或者为该交集的子集)；当所述预定逻辑信道组对应的目的标识对应多个业务类型时，确定所述第二备选载波集合为所述预定逻辑信道组所包含的各业务类型的载波集合的并集(或者为该并集的子集)。在本实施例中，通过per UE(每个UE)配置的载波集合A(对应于第二载波集合)和per逻辑信道组(每个逻辑信道组)或Destination ID确定的载波集合C(对应于第二备选载波集合)的交集来最终确定一个逻辑信道组或Destination ID能够使用的载波集合(对应于第一载波集合)。下面以具体实施例来说明本实施例。
具体实施例三
在本具体实施例中，来说明确定(或称为配置)UE用于Sidelink传输的第i个逻辑信道组所对应的载波集合B i(对应于第一载波集合)的方法。一个逻辑信道组中的逻辑信道具有相同的Destination ID(即，目的标识)，即一个逻辑信道组i只对应一个Destination ID i，本实例中还假定，确定(或称为配置)UE用于Sidelink传输的第i个逻辑信道组所对应的载波集合B i等同于确定(或称为配置)UE用于Sidelink传输的Destination ID i所对应的载波集合B i。一个业务类型会对应一个Destination ID和一个能够传输该业务的载波集合；同时不同的业务可能对应相同的Destination ID；不同的业务可能对应的载波集合也可能完全一样，部分一样或没有交集。下面结合具体的对应关系来进行说明：
方法一：限定业务类型和Destination ID是一一对应，或限定只有对应相同的载波集合的业务类型才可以对应相同的Destination ID。确定(或称为配置)UE用于Sidelink传输的Destination ID i所对应的载波集合B i(对应于第一载波集合)包括：，有一个或多个业务类型对应Destination ID i。假设对应业务类型个数为N，则Destination ID i或逻辑信道组i包含的第j个业务对应的载波集合为C i,j，如上所述，这里假设所有N个业务对应的载波集合相同，则确定Destination ID i对应的备选载波集合为C i＝C i,1＝C i,2.....＝C i,N(对应于第二备选载波集合)。
则确定(或称为配置)UE用于Sidelink传输的Destination ID i所对应的载波集合B i(对应于第一载波集合)属于或等于备选载波集合为C i(对应于第二备选载波集合)和确定(或称为配置)的UE用于Sidelink传输的载波集合A(对应于第二载波集合)的交集。即：
Figure PCTCN2019074116-appb-000001
方法二：多个业务能够对应同一个Destination ID，但限定只有多个业务的载波集合的交集不为空才可以对应相同的Destination ID。
确定UE用于Sidelink传输的Destination ID i所对应的载波集合B i(对应于第一载波集合)包括，有一个或多个业务类型对应Destination ID i。假设对应业务类型个数为N，则Destination ID i或逻辑信道组i包含的第j个业务对应的载波集合为C i,j。则确定Destination ID i对应的备选载波集合为C i(对应于第二备选载波集合)属于各个业务载波集合的交集，可选地，
Figure PCTCN2019074116-appb-000002
同样的载波集合B i为：
Figure PCTCN2019074116-appb-000003
方法三：多个业务能够对应同一个Destination ID，多个业务的载波集合可以相同，完全不同或部分相同。如图6所示，确定(或称为配置)UE 用于Sidelink传输的Destination ID i所对应的载波集合B i(对应于第一载波集合)包括，有一个或多个业务类型对应Destination ID i。假设对应业务类型个数为N，则Destination ID i或逻辑信道组i包含的第j个业务对应的载波集合为C i,j。则确定Destination ID i对应的备选载波集合为C i(对应于第二备选载波集合)属于各个业务载波集合的合集，可选地
Figure PCTCN2019074116-appb-000004
同样的载波集合B i(对应于第一载波集合)为：
Figure PCTCN2019074116-appb-000005
具体实施例四
本实例用于说明另一种确定(或称为配置)UE用于Sidelink传输的第i个逻辑信道组所对应的载波集合B i的方法。所述一个逻辑信道组中的逻辑信道具有相同的Destination ID，不同的逻辑信道组可也能对应相同的Destination ID。即使对应相同的Destination ID，不同的逻辑信道组仍然可以对应不同的载波集合B i(对应于第一载波集合)。
有一个或多个业务类型承载在逻辑信道组i上。假设对应业务类型个数为N，则逻辑信道组i包含的第j个业务对应的载波集合为C i,j，这里假设所有N个业务对应的载波集合相同，则确定逻辑信道组i对应的备选载波集合为C i＝C i,1＝C i,2.....＝C i,N(对应于第二备选载波集合)。则确定(或称为配置)UE用于Sidelink传输的逻辑信道组i所对应的载波集合B i(对应于第一载波集合)属于或等于备选载波集合为C i(对应于第二备选载波集合)和确定(或称为配置)的UE用于Sidelink传输的载波集合A(对应于第二载波集合)的交集。即：
Figure PCTCN2019074116-appb-000006
若多个逻辑信道组对应同一个Destination ID，则理论上多个逻辑信道组的数据可以被复用在同一个或多个协议数据单元(PDU，protocol data unit)中，一个PDU会承载在一个载波上。但是在进行多个逻辑信道组的 复用时，对于每个逻辑信道组，都必须满足，承载逻辑信道组i数据包的PDU所在的载波必须属于逻辑信道组i对应的载波集合B i(对应于第一载波集合)。对于本实例中的一个特例，一个逻辑信道组只包含一个逻辑信道时，确定(或称为配置)UE用于Sidelink传输的第i个逻辑信道组所对应的载波集合B i等同于确定(或称为配置)UE用于Sidelink传输的第i个逻辑信道所对应的载波集合B i。
在一个可选实施例中，确定上述UE进行所述边链路Sidelink传输的第二载波集合包括：由所述UE的协议栈高层确定所述第二载波集合；由所述UE的协议栈高层通过内部接口将所述第二载波集合配置给所述UE的协议栈低层。在本实施例中，协议栈的高层(例如UE自己的RRC层，或基站)根据上述实例确定载波集合A(对应于第二备选载波集合)并通过内部接口或信令配置给UE的低层实体(例如，MAC层或PHY层)或UE。
在一个可选实施例中，根据上述预定逻辑信道组所包含业务类型对应的载波集合确定所述预定逻辑信道组对应的第二备选载波集合包括：由所述UE的协议栈高层根据所述预定逻辑信道组所包含业务类型对应的载波集合确定所述第二备选载波集合；以及，由所述UE的协议栈高层通过内部接口将所述第二备选载波集合配置给所述UE的协议栈低层；确定所述第二载波集合和所述第二备选载波集合的交集的子集为所述第一载波集合包括：由所述UE的协议栈低层确定所述第二载波集合和所述第二备选载波集合的交集的子集为所述第一载波集合。在本实施例中，协议栈的高层根据上述实例中的方法确定Destination ID i或逻辑信道组i对应的备选载波集合C i并通过内部接口或信令配置给UE的低层实体或UE；UE或UE的低层实体根据的上述实例中的方法，确定UE用于Sidelink传输的Destination ID i或逻辑信道组i所对应的载波集合B i(对应于第一载波集合)，若有多个Destination ID或逻辑信道组，则对每个都使用上述操作。
在一个可选实施例中，根据上述预定逻辑信道组所包含业务类型对应的载波集合确定上述预定逻辑信道组对应的第二备选载波集合包括：由所 述UE的协议栈高层根据所述预定逻辑信道组所包含业务类型对应的载波集合确定所述第二备选载波集合；确定所述第二载波集合和所述第二备选载波集合的交集的子集为所述第一载波集合包括：由所述UE的协议栈高层确定所述第二载波集合和所述第二备选载波集合的交集的子集为所述第一载波集合；以及由所述UE的协议栈高层通过内部接口将所述第一载波集合配置给所述UE的协议栈低层。在本实施例中，协议栈的高层根据上述实例中的方法确定Destination ID i或逻辑信道组i对应的备选载波集合C i(对应于第二备选载波集合)并进一步确定UE用于Sidelink传输的Destination ID i或逻辑信道组i所对应的载波集合B i(对应于第一载波集合)，并通过内部接口或信令将B i配置给UE的低层实体或UE，若有多个Destination ID或逻辑信道组，则对每个都使用上述操作。
在一个可选实施例中，上述UE的协议栈高层包括所述UE的无线资源控制RRC层；所述UE的协议栈低层包括所述UE的媒体接入控制MAC层或物理PHY层。在本实施例中，不论是上述实施例中的哪种方法，具体的确定(或称为配置)UE用于Sidelink传输的Destination ID i或逻辑信道组i所对应的载波集合B i(对应于第一载波集合)的过程可以为：协议栈的高层(例如UE自己的RRC层，或基站)根据上述实例确定载波集合A并通过内部接口或信令配置给UE的低层实体(例如，MAC层或PHY层)或UE；
在一个可选实施例中，在确定用于用户设备UE进行边链路Sidelink传输的预定逻辑信道组所对应的第一载波集合之后，上述方法还包括：根据所述预定逻辑信道组中各逻辑信道中数据包的优先级(例如：PPPP(ProSe Per-Packet Priority，每个邻近服务数据包的优先级))以及所述第一载波集合中各载波的CBR从所述第一载波集合中确定各逻辑信道对应的载波集合。在本实施例中，用于Sidelink传输的Destination ID i或逻辑信道组i所对应的载波集合B i(对应于第一载波集合)确定之后，可以进一步限定Destination ID i或逻辑信道组i对应的或包含的一个或多个逻辑信道所能使用的载波集合。即使属于同一个逻辑信道组，每个逻辑信道对 应的每个邻近服务数据包的优先级PPPP也不尽相同。例如，一个逻辑信道组i包含K个逻辑信道，编号1,2，...K，则第k个逻辑信道中数据包的每个邻近服务数据包的优先级PPPP为PPPP i,k，根据PPPP i,k和各个载波上的CBR确定其能够使用的载波集合，该集合可以定义为D i,k，D i,k属于B i的子集。
可选地，确定D i,k的方法为：根据目前的技术，UE可以获得某个载波的忙闲程度CBR。根据配置的CBR-PPPP表确定某个逻辑信道是否能够使用某个载波，对于每个PPPP的数据包或逻辑信道，在不同的CBR范围内会对应不同能够占用的资源量限制(cr-Limit,channel occupancy ratio maximum limit)，能够使用的发送参数(MCS，功率等参数)。如表1所示，若某个逻辑信道的PPPP在当前载波的CBR处于某个范围时，通过查表不满足要求的cr-Limit和Tx parameters，则该逻辑信道就不能使用该载波：
表1
Figure PCTCN2019074116-appb-000007
上述CBR-PPPP表(即，表1)可以是每个载波配置一个或者所有载波配置同一个。另外，除了上述PPPP-CBR表外，还可以其他表格或对应关系，限制逻辑信道能够使用的载波。例如：(1)对于某个载波，为每个 PPPP设置CBR门限值，若该载波的CBR超过该门限值，则对应PPPP的逻辑信道将不能使用该载波。(2)某些逻辑信道不可以在同一个载波上传输，例如两个逻辑信道用于重复传输同一组数据以提高可靠性，这一对逻辑信道将会被标识出来，当MAC进行资源调度时，这两个逻辑信道的数据就必须占用不同的载波或载波集合。(3)高层为每个逻辑信道设置一个对应载波集合，这些载波集合都是B i的子集，逻辑信道对应的载波集合可以根据逻辑信道承载的业务等信息确定。
另外，本实例用于说明本公开中所述Sidelink载波聚合情况下的数据面的结构，如图7所例示，一个逻辑信道对应一个RLC(Radio Link Control，无线链路控制)实体和一个PDCP(Packet Data Convergence Protocol，分组数据汇聚协议层)实体，用于Sidelink发送时，RLC主要功能用于数据分段(segement)，PDCP实体用于加密，头压缩等操作。同时一个逻辑信道内的包，都对应同一个PPPP和同一个Destination ID(即，目的标识)。具有同样Destination ID的M个逻辑信道可以被MAC实体复用到同一个或同一组MAC层PDU(Protocol Data Unit，协议数据单元)中，假设复用到位于N个载波上的N个PDU。具体的哪个逻辑信道复用到哪个载波上的PDU上，跟逻辑信道数据包的PPPP有关，跟载波CBR有关，也和该逻辑信道所对应的载波集合有关，具体如上述所述的载波集合的确定方法。通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
