下面先对本公开所提及的相关概念进行简要说明如下。
1、LTE直接通信接口分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)重复(duplication)机制
LTE直接通信接口从空口设计看只支持广播传输方式。
为了提升直接通信接口数据传输可靠性引入了PDCP duplication机制。PDCP duplication即PDCP层的一个无线承载(对应一个PDCP实体),在无线链路控制(Radio Link Control,RLC)层通过多个逻辑信道(Logical Channel,每个逻辑信道对应一个RLC实体)分别进行传输,RLC实体将数据传输至媒体接入控制(Media Access Control,MAC)层,示意图如图1所示。
LTE直接通信接口无线承载的建立完全取决于终端实现,基站不参与。基站只会配置一个接近业务包可靠性(Per ProSe Packet Reliability,PPPR)门限,终端直接根据直接通信接口无线承载对应的PPPR是否低于门限,判断是否激活PDCP duplication。
对于新空口(New Radio,NR)SL,与LTE SL不同,NR SL支持SL单播传输方式。对于SL单播传输,LTE分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)重复(duplication)中静态配置传输路径可用载波集合的方式不适用于NR SL单播传输方式。
下面结合附图介绍本公开的实施例。本公开实施例提供的频率资源获取、确定方法、装置、终端设备及网络设备可以应用于无线通信***中。该无线通信***可以为采用第五代(5th Generation,5G)移动通信技术的***(以下均简称为5G***),所述领域技术人员可以了解,5G NR***仅为示例,不为限制。
本公开实施例提供了一种频率资源获取、确定方法、装置、终端设备及网络设备,以解决如何配置SL PDCP duplication每个传输路径对应的SL频率资源集合,提升SL PDCP duplication的增益的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图2所示,本公开实施例提供一种频率资源获取方法,由第一终端设备执行,包括:
步骤S201,基于第一信息,获取分组数据汇聚协议PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合;
其中,所述第一信息包括以下至少一项:
A11、第一终端设备与第二终端设备之间单播连接的层二源地址与层二目标地址的组合;
A12、第一指示信息,所述第一指示信息为第一终端设备确定的直接通信接口频率资源的指示信息;
A13、第二指示信息,所述第二指示信息为所述第一终端设备从第二终端设备接收的直接通信接口频率资源的指示信息。
本公开实施例中,通过基于第一信息动态的获取PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合,避免了只能静态配置直接通信接口频率资源集合造成的影响SL PDCP duplication的性能的问题。
可选地,本公开实施例所说的第一终端设备指的是发送终端,即直接通信过程中进行数据发送的终端设备;第二终端设备指的是接收终端,即直接通信过程中进行数据接收的终端设备。

可选地,本公开的另一实施例中,所述直接通信接口频率资源集合的个数与PDCP重复传输情况下的传输路径的个数相同。
也就是说,SLRB在PDCP重复传输情况下存在多少条传输路径,便会存在多少个直接通信接口频率资源集合。
可选地,本公开的另一实施例中,所述直接通信接口频率资源集合中的直接通信接口频率资源包括:
直接通信接口载波;和/或
直接通信接口带宽部分(BandWidth Part,BWP)。
可选地,本公开的另一实施例中,所述直接通信接口频率资源集合中包含一个或多个直接通信接口频率资源。
可选地,在所述直接通信接口频率资源集合中包括至少两个频率资源的情况下,所述方法,还包括:
针对直接通信接口SLRB在PDCP重复传输情况下每条传输路径对应的逻辑信道,在所述传输路径对应的直接通信接口频率资源集合中选择一个目标直接通信接口频率资源进行数据传输。
需要说明的是,在此种情况下,若第一终端设备采用终端自选的资源确定方式,则需要在直接通信接口频率资源集合选择一个直接通信接口频率资源进行数据的传输,例如,第一终端设备随机从直接通信接口频率资源集合选择一个资源使用。需要说明的是,上述的随机从直接通信接口频率资源集合选择一个资源的实现方式仅仅为举例,任何从直接通信接口频率资源集合选择一个资源的实现方式均属于本公开的保护范围。
可选地,本公开的一实施例中,所述第一指示信息包括以下至少一项:
A121、第一终端设备在每个直接通信接口频率资源上的信道占用比(Channel Busy Ratio,CBR)或者信道占用(channel occupy,CO);

A134、第二终端设备期望的直接通信接口PDCP重复情况下可以使用的直通链路参数频率资源集合。
这里需要说明的是,该第二指示信息通常是由第二终端设备发送给第一终端设备的。具体的,第二终端设备通过直接通信接口将第二指示信息发送给第一终端设备。
需要说明的是,本公开实施例中给出了第一终端设备获取PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合的两种方式,一种是第一终端设备直接基于第一信息自己确定,即第一终端设备根据第一信息,确定PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合,另一种是第一终端设备直接接收网络设备发送的PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合,即第一终端设备将所述第一信息发送给为第一终端设备服务的网络设备,接收所述网络设备发送的PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合,所述直接通信接口频率资源集合由所述网络设备基于所述第一信息确定,下面分别对这两种实现方式进行说明如下。
方式一、第一终端设备直接基于第一信息自己确定
在此种实现方式下,第一终端设备确定直接通信接口频率资源集合的方式包括以下一项:
B11、根据第一信息确定当前可用的SL频率资源集合,然后将所述SL频率资源集合内的SL频率资源按照CBR或CO从低到高的顺序排序,然后分别将所述SL频率资源依次分配给直接通信接口PDCP重复传输的每条传输路径;
需要说明的是,此种直接通信接口频率资源集合的确定方式下,每个直接通信接口频率资源集合中仅包括一个直接通信接口频率资源。
B12、根据第一信息确定当前可用的SL频率资源集合,然后根据直接通信接口PDCP重复传输的传输路径个数将所述SL频率资源集合内的SL频率
资源随机分配为和所述传输路径个数相同的组数,将每组SL频率资源作为直接通信接口PDCP重复传输下一条传输对应的SL频率资源集合。
需要说明的是,此种直接通信接口频率资源集合的确定方式下,每个直接通信接口频率资源集合中通常包括一个或多个(即至少两个)直接通信接口频率资源。
可选地,在此种情况下,当第一终端确定得到该直接通信接口频率资源集合之后,还应当通过直接通信接口PDCP重复传输配置信令或直接通信接口PDCP重复传输激活信令,向第二终端设备发送PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合。
可选地,所述直接通信接口PDCP重复传输激活信令包括以下至少一项:RRC信令、媒体接入控制控制单元(MAC CE)或物理层信令。
可选地,此种情况下,若第一终端设备采用网络配置资源分配模式,则第一终端设备还应当将所述PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合发送给网络设备,以便于网络设备对直接通信接口频率资源集合的使用。
方式二、第一终端设备直接接收网络设备发送的PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合
可选地,在此种实现方式下,所述将所述第一信息发送给为第一终端设备服务的网络设备,包括:
通过直接通信接口终端信息、终端辅助信息和Uu接口RRC信令中的至少一项将所述第一信息发送给所述网络设备。
可选地,在此种情况下,当第一终端设备获取到网络设备发送的直接通信接口频率资源集合之后,还应当通过直接通信接口PDCP重复传输配置信令或直接通信接口PDCP重复传输激活信令,向第二终端设备发送PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合。
可选地,所述直接通信接口PDCP重复传输激活信令包括以下至少一项:RRC信令、MAC CE或物理层信令。
还需要说明的是,网络设备确定PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合的方式可以采用上述的B11或B12。
可选地,本公开的另一实施例中,所述方法还包括:
基于第二信息,获取直接通信接口无线承载(SLRB)在PDCP重复传输情况下每条传输路径对应的逻辑信道标识(Logical Channel Identity,LCID)。
具体地,第一终端设备可以采用如下方式中的一项获取SLRB在PDCP重复传输情况下每条传输路径对应的LCID:
C11、根据第二信息,确定SLRB在PDCP重复传输情况下每条传输路径对应的LCID;
此种情况指的是第一终端设备自己基于第二信息确定SLRB在PDCP重复传输情况下每条传输路径对应的LCID。
可选地,第一终端设备确定每条传输路径对应的LCID的具体实现方式可以包括如下一项:
C111、从可用的LCID中随机选择N个LCID,将N个LCID分别作为每条传输路径对应的LCID,LCID与传输路径一一对应,N等于直接通信接口PDCP重复传输情况下的传输路径的个数;
需要说明的是,此种实现方式下是将随机确定得到N个LCID,然后将N个LCID分别给N个传输路径。可用的LCID可以理解为未被占用的逻辑信道对应的LCID,也可以简称为未被占用的LCID;也就是说,直接通信接口发送终端可以从当前未被占用的LCID中随机选择和直接通信接口PDCP重复传输传输路径相同个数的LCID,并将所述选择出来的LCID分别作为每条传输路径对应的LCID。
C112、在第一LCID集合中随机选择第一LCID作为直接通信接口PDCP重复传输中一条传输路径的LCID,基于第一LCID以及不同传输路径的LCID之间的关联关系,确定直接通信接口PDCP重复传输中其他传输路径的LCID,所述第一LCID为可用的LCID,所述第一LCID集合中包括:第一终端设备和第二终端设备的直接通信接口可用的LCID。
需要说明的是,此种情况下,是先确定一个传输路径对应的LCID,其他路径的LCID与已经确定的传输路径的LCID具有关联关系,该关联关系可以是协议约定或网络设备配置的。例如,其他路径的LCID与已经确定的传输路径的LCID的差值小于或等于某一阈值;例如,其他路径的LCID与已经确
定的传输路径的LCID共同构成等差数列、等比数列等;例如,LCID=2的LCH,与之有关联关系的SL PDCP duplication的LCID是LCID=12。需要说明的是,此处仅仅是关联关系的一个举例,任意通过关联关系的方式确定其他路径的LCID的方式均属于本公开的保护范围。
也就是说,直接通信接口发送终端可以在第一LCID集合中随机选择一个未被占用的LCID作为直接通信接口PDCP重复传输中一条传输路径的LCID,然后根据所述LCID以及预先约定的直接通信接口PDCP重复传输情况下不同传输路径LCID之间的关联关系确定其他传输路径对应的LCID。
C12、将所述第二信息发送给为第一终端设备服务的网络设备,接收网络设备发送的SLRB在PDCP重复传输情况下每条传输路径对应的LCID,所述LCID由为第一终端服务的网络设备基于第二信息确定;
需要说明的是,此种情况下,每条传输路径对应的LCID是由网络设备基于第二信息确定并传输给第一终端设备的;可选地,网络设备通常采用C111或C112的方式进行每条传输路径对应的LCID的确定。
可选地,在此种情况下,第一终端设备通过直接通信接口终端信息(SidelinkUEInformation)、终端辅助信息(UEAssistanceInformation)和Uu接口RRC信令中的至少一项将所述第二信息发送给所述网络设备。
需要说明的是,所述第二信息包括以下至少一项:
C21、第一终端设备在第一终端设备和第二终端设备之间单播连接下可用的LCID;
C22、第一终端设备在第一终端设备和第二终端设备之间单播连接下推荐的用于直接通信接口PDCP重复传输的LCID;
C23、第一终端设备在第一终端设备和第二终端设备之间单播连接下预留给直接通信接口PDCP重复传输的LCID。
需要说明的是,通过本公开的至少一个实施例提供了一种直接通信接口重复传输资源的配置方法,通过该方法可以解决直接通信接口发送终端或者直接通信接口发送终端归属的网络设备如何配置直接通信接口PDCP重复传输下每个传输路径对应的直接通信接口频率资源集合的问题,更好的提升直接通信接口PDCP重复传输的增益。

下面从发送终端与接收终端的角度对本公开的具体应用方式进行详细说明如下。
应用情况一、发送终端确定PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合以及每条传输路径对应的LCID
主要包括如下流程:
步骤S11,直接通信接口发送终端确定直接通信接口PDCP重复传输情况下每条传输路径可用的直接通信接口频率资源集合以及每条传输路径对应的LCID;
需要说明的是,此种情况下,由直接通信接口发送终端确定SLRB在直接通信接口PDCP重复传输情况下每条传输路径对应的LCID和所述每条传输路径对应的直接通信接口频率资源集合。
具体的,直接通信接口发送终端具体如何确定SLRB在直接通信接口PDCP duplication情况下每条传输路径对应的LCID和所述每条传输路径对应的直接通信接口频率资源集合可以取决于直接通信接口发送终端的实现。举例说明如下:
LCID确定方式可以是但不限于如下之一:
