相互靠近的设备和设备之间允许直接进行通信。定义终端之间直接通信的链路为Sidelink(直通链路)。直接通信的设备可以均是在网的，或者均是脱网的，还可以是部分设备在网，部分设备脱网。
NR(New Radio，新空口)系统中，一个逻辑信道的数据可能会同时通过多个载波进行传输。如果聚合的载波使用同一种无线接入技术，那么比较直接的方式是只使用一个MAC(Medium Access Control，媒体接入控制)实体。通过MAC实体中的调度功能，将一个逻辑信道的数据调度到不同载波，或者小区，或者BWP(Bandwidth Part,带宽部分)上传输。由于发送终端仍然使用同一个RLC(Radio Link Control，无线链路控制)实体，所以接收终端可以正确接收数据。但是如果聚合的载波使用的是不同无线接入技术，比如同时使用LTE(Long Term Evolution，长期演进)sidelink和NR sidelink传输，那么，如何将一个逻辑信道的数据调度到不同的无线接入技术对应的不同载波，或者小区，或者BWP上传输，相关技术中并没有明确规定。因此，当一个逻辑信道的数据同时通过直接通信接口多个载波进行传输时，如何使接收终端正确的接收数据，是需要研究的技术问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的信息处理方法的流程图，应用于发送终端，如图1所示，包括以下步骤：
步骤101、对于直接通信接口，确定对无线承载是否启用承载分离的传输方式。
在本公开实施例中，所述承载分离是指终端的一个承载通过多个载波，或者小区或者BWP传输，且所述多个载波，或者小区或者BWP对应不同的MAC实体。
在本公开实施例中，可利用以下任意一种方式，确定对无线承载是否启用承载分离的传输方式：
预配置；发送终端自行决定；发送终端根据从网络侧设备获取的配置确定，所述网络侧设备决定对所述无线承载是否启用承载分离的传输方式。
根据不同的需求，可采用以上不同的确定方式，从而增加了灵活性。
步骤102、在确定对所述无线承载启用承载分离的传输方式的情况下，获取所述无线承载对应的PDCP实体和RLC实体之间的关联关系；其中，所述PDCP实体对应的RLC实体的数量为N，N为整数且N≥2。
同时，在本公开实施例中，为保证可靠通信，不同的RLC实体对应不同的MAC实体。
在本公开实施例中，发送终端可通过如下方式获取上述对应关系：
方式一、发送终端获取预先约定的所述无线承载对应的多个RLC层LCID(Logical Channel Identity，逻辑信道标识)之间的关联关系。
其中，预先约定的方式包括以下任意一种：在协议中预先约定；在发送终端和接收终端的预配置信息中约定。

方式三、发送终端自行决定所述无线承载对应的多个RLC层逻辑信道标识之间的关联关系。
在这种情况下，发送终端还可通过直接通信接口向接收终端指示所述关联关系。具体包括以下几种方式：
(1)发送终端利用直接通信接口控制面信令，向接收终端指示所述无线承载对应的多个RLC层逻辑信道标识之间的关联关系。
所述直接通信接口控制面信令包括以下任意一种：直接通信接口的RRC信令；直接通信接口的MAC信令；直接通信接口的物理层信令。
在实际应用中，所述直接通信接口控制面信令中至少包含以下内容之一：

在本公开实施例中，在确定对所述无线承载启用承载分离的传输方式的情况下，获取所述无线承载对应的PDCP实体和RLC实体之间的关联关系， 从而利用本公开实施例可保证当一个逻辑信道的数据同时通过直接通信接口多个载波进行传输时，接收终端可以正确接收。
参见图2，图2是本公开实施例提供的信息处理方法的流程图，应用于接收终端，如图2所示，包括以下步骤：
步骤201、获取无线承载对应的PDCP实体和RLC实体之间的关联关系。
其中，所述无线承载为直接通信接口启用了承载分离的传输方式的承载；所述PDCP实体对应的RLC实体的数量为N，N为整数且N≥2。
在本公开实施例中，接收终端可通过以下任一方式获取上述关联关系：
方式一、接收终端获取预先约定的所述无线承载对应的多个RLC层逻辑信道标识之间的关联关系。
其中，预先约定的方式包括以下任意一种：在协议中预先约定；在发送终端和接收终端的预配置信息中约定。

方式三、接收终端接收发送终端发送的直接通信接口控制面信令，并根据所述直接通信接口控制面信令，获取所述无线承载对应的多个RLC层逻辑信道标识之间的关联关系。

其中，所述PDCP实体的标识携带在PDCP PDU的头部或者数据部分；或者，所述PDCP实体的标识携带在RLC PDU的头部或者数据部分。
步骤202、根据所述关联关系对接收的数据包进行处理。
具体的，在此步骤中，接收终端首先确定接收的数据包是否有对应的RLC 实体。在确定没有对应的RLC实体的情况下，建立对应的RLC实体。之后，根据所述关联关系以及所述接收的数据包的逻辑信道标识，确定目标数据包是否有对应的PDCP实体。在确定没有对应的PDCP实体的情况下，建立对应的PDCP实体；在确定有对应的PDCP实体的情况下，将所述接收的数据包对应的RLC实体和所述PDCP实体关联。其中，所述目标数据包的逻辑信道标识与所述接收的数据包的逻辑信道标识具有承载分离关联关系。
在本公开实施例中，在确定对所述无线承载启用承载分离的传输方式的情况下，获取所述无线承载对应的PDCP实体和RLC实体之间的关联关系，从而利用本公开实施例可保证当一个逻辑信道的数据同时通过直接通信接口多个载波进行传输时，接收终端可以正确接收。
参见图3，图3是本公开实施例提供的信息处理方法的流程图，应用于网络侧设备，如图3所示，包括以下步骤：
步骤301、向终端发送配置信令，在所述配置信令中包括无线承载对应的PDCP实体和RLC实体之间的关联关系。
其中，所述无线承载为直接通信接口启用了承载分离的传输方式的承载；所述PDCP实体对应的RLC实体的数量为N，N为整数且N≥2。所述关联关系可以是，所述无线承载对应的多个RLC层逻辑信道标识之间的关联关系。
在本公开实施例中，所述终端包括发送终端和接收终端，此步骤具体的为：通过广播或者专用信令的方式，将所述无线承载对应的多个RLC层逻辑信道标识之间的关联关系配置给发送终端和/或接收终端。也即，该关联关系可配置给发送终端和接收终端中的任意一个或者两个。如果发送给其中的一个，那么收到该关联关系的终端，可将该关联关系发送给另外的一个终端。
在本公开实施例中，在确定对所述无线承载启用承载分离的传输方式的情况下，获取所述无线承载对应的PDCP实体和RLC实体之间的关联关系，从而利用本公开实施例可保证当一个逻辑信道的数据同时通过直接通信接口多个载波进行传输时，接收终端可以正确接收。
在上述实施例的基础上，所述网络侧设备还可决定所述无线承载是否启用承载分离的传输方式。通过这种方式，可进一步提高通信效率。
在本公开实施例中，提出了一种直接通信接口使用不同无线接入技术的 载波聚合方案。通过该方案，可以保证当一个逻辑信道的数据同时通过直接通信接口多个载波进行传输时，接收端可以正确接收。在以下的实施例中，将作为发送方的终端称为发送终端，将作为接收终端的终端称为接收终端。
本公开实施例的核心思想是对于直接通信接口，发送终端决定对一个承载是否启用承载分离的传输方式。如果决定针对一个承载启用承载分离，那么，所述承载对应的PDCP实体需要关联到N(N为整数，且N≥2)个不同的RLC实体，并且所述多个不同的RLC实体需要对应不同MAC实体。本公开实施例的直接通信接口承载分离的网络架构如图4所示。同时，还需要保证所述发送终端和接收终端对所述启用了承载分离的承载所对应的PDCP实体和RLC实体之间的关系理解一致。例如，启用了承载分离的承载所对应的PDCP实体和RLC实体之间的关系，需要告知接收终端。
以下，结合不同的实施例描述一下具体的实现过程。
如图5所示，本公开实施例的信息处理方法包括：
步骤501、发送终端确定特定承载是否需要启用承载分离。
对于直接通信接口，确定对一个直接通信承载(即无线承载)是否启用承载分离的传输方式。其中，一个直接通信承载是否启用承载分离的传输方式确定方法包括以下几种：
预配置；发送终端自己决定；网络侧设备决定并配置给发送终端。
如果决定对针对一个承载启用承载分离，那么启用承载分离的承载对应的PDCP实体需要关联到N(N为整数，N≥2)个不同的RLC实体，并且需要保证所述发送终端和接收终端对所述启用了承载分离的承载所对应的PDCP实体和RLC实体之间的关系理解一致。在此实施例中，具体实现方式可以是：约定启用了承载分离的承载对应的多个RLC层逻辑信道标识之间的关联关系。具体约定方式可以是但不限于如下方式之一：
(1)协议中约定。
比如，协议中明确约定：当前使用LCID编号为m的承载一旦启用承载分离，其对应的用于承载分离数据的另一个LCID编号必须为n。
(2)预配置给终端。
比如，在终端预配置信息中明确约定：当前使用LCID编号为m的承载 一旦启用承载分离，其对应的用于承载分离数据的另一个LCID编号必须为n。
(3)收发双方自行约定，比如发送终端或者接收终端将所述关联关系通知给对端。
比如，发送终端确定：当前使用LCID编号为m的承载一旦启用承载分离，其对应的用于承载分离数据的另一个LCID编号必须为n。发送终端将所述关联关系通知给接收终端。
步骤502、发送终端执行直接通信数据的发送。
步骤503、接收终端进行数据接收处理。
接收终端RLC/PDCP实体建立过程，包括：
接收终端接收到一个数据包，确定该数据包对应的RLC实体是否已经建立。如果没有，则建立对应的RLC实体。
接收终端确定所述数据包携带的LCID，判断与之有承载分离关联关系的其他LCID对应的数据是否已经有对应的PDCP实体。如果有，则将所述数据对应的RLC实体和所述PDCP实体关联；如果没有，则新建PDCP实体。
一旦完成相关接收终端PDCP/RLC实体建立，接收终端按照正常的数据处理流程进行接收数据处理即可。
如图6所示，本公开实施例的信息处理方法包括：
步骤601、发送终端确定特定承载是否需要启用承载分离。

预配置；发送终端自己决定；网络侧设备决定并配置给发送终端。
如果决定对针对一个承载启用承载分离，那么启用承载分离的承载对应的PDCP实体需要关联到N(N为整数，N≥2)个不同的RLC实体。
步骤602、发送终端将启用了承载分离的承载PDCP/RLC实体关联关系通知接收终端。
发送终端需要将所述启用了承载分离的承载所对应的PDCP实体和RLC实体之间的关系需要告知所述接收终端，具体实现方式可以是：利用直接通信接口控制面信令配置启用了承载分离的承载对应的多个RLC层逻辑信道标 识之间的关联关系。具体的控制面信令可以是但不限于：
(1)直接通信接口的RRC信令。
举例说明，可以使用直接通信接口的RRC重配信令，通知接收终端当前使用LCID编号为m的承载启用了承载分离，且其对应的用于承载分离数据的另一个LCID编号必须为n。
(2)直接通信接口的MAC信令。
举例说明，具体的MAC信令，需要包含启用承载分离的承载多个LCID。比如如果启用承载分离的承载最多使用RLC实体传输，那么MAC CE(Control Element，控制单元)格式如下举例如图7所示。其中，R表示预留域。
(3)直接通信接口的物理层信令。
举例说明，在物理层信令中增加LCID指示信息，指示启用了承载分离的承载多个LCID之间的关联关系。
步骤603、发送终端执行直接通信数据的发送。
步骤604、接收终端进行数据接收处理。
接收终端RLC/PDCP实体建立过程，包括：

接收终端确定所述数据包携带的LCID，判断与之有承载分离关联关系的其他LCID对应的数据是否已经有对应的PDCP实体。如果有，则将所述数据对应的RLC实体和所述PDCP实体关联；如果没有，则新建PDCP实体。
一旦完成相关接收终端PDCP/RLC实体建立，接收终端按照正常的数据处理流程进行接收数据处理即可。

如果发送终端决定对针对一个承载启用承载分离，那么启用承载分离的 承载对应的PDCP实体需要关联到N(N为整数，N≥2)个不同的RLC实体。
步骤802、发送终端将启用了承载分离的承载PDCP/RLC实体关联关系通知接收终端。
发送终端需要将所述启用了承载分离的承载所对应的PDCP实体和RLC实体之间的关系需要告知所述接收终端，具体实现方式可以是：利用直接通信接口用户面数据携带所述数据包在发送终端对应的PDCP实体的标识。具体的，所述PDCP实体的标识可以携带在以下任意部分：
PDCP PDU头或者数据部分；RLC PDU头或者数据部分。
举例说明，以RLC UM(Unacknowledged Mode，非确认模式)PDU为例，可以利用图9中的三个R bit指示其对应的PDCP实体编号。所述PDCP实体编号可以是一个绝对编号或者相对编号。以相对编号为例，如第一个启用承载分离的承载，其PDCP实体编号可以是000，第二个启用承载分离的承载，其PDCP实体编号可以是001，依次类推。其中，R表示预留域，SI表示分段指示(Segmentation Info)，Data表示数据。

对于直接通信接口，确定对一个直接通信承载(即无线承载)是否启用承载分离的传输方式。其中，一个直接通信承载是否启用承载分离的传输方式确定方法包括以下几种：
预配置；发送终端自己决定；网络侧设备决定并配置给发送终端。

具体实现方式可以是：通过网络侧设备将所述关联关系分别配置给发送终端和接收终端，网络侧的配置信令包括但不限于：(1)广播；(2)专用信令。
比如，在网络侧设备发送的SIB(System Information Block，系统信息块)中广播当前使用LCID编号为m的承载一旦启用承载分离，其对应的用于承载分离数据的另一个LCID编号必须为n。
步骤1002、发送终端执行直接通信数据的发送。
步骤1003、接收终端进行数据接收处理。

接收终端接收到一个数据包，确定该数据包对应的RLC实体是否已经建立。如果没有，则建立对应的RLC实体。
接收终端确定所述数据包携带的LCID，判断与之有承载分离关联关系的其他LCID对应的数据是否已经有对应的PDCP实体。如果有，则将所述数据对应的RLC实体和所述PDCP实体关联；如果没有，则新建PDCP实体。
一旦完成相关接收终端PDCP/RLC实体建立，接收终端按照正常的数据处理流程进行接收数据处理即可。
