具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
应理解,本公开实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、5G系统,或者说新无线(New Radio,NR)系统,或者为后续演进通信系统。
在本公开的一些实施例中,终端设备可以包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment,UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等,该终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本公开的一些实施例中,网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站,所述基站可以包括各种形式的宏基站,微基站,中继站,接入点等。在采用不同的无线接入技术的系统中,具有基站功能的设备的名称可能会有所不同。例如在LTE网络中,称为演进的节点B(Evolved NodeB,eNB或eNodeB),在第三代(3rd Generation,3G)网络中,称为节点B(Node B),或者后续演进通信系统中 的网络设备等等,然用词并不构成限制。
如图1所示,本公开的一个实施例提供一种SL传输方法100,该方法可以由终端设备执行,包括如下步骤:
S102:根据第一配置信息进行配置,使得所述终端设备同时工作在Mode1和Mode 2。
可选地,上述第一配置信息可以通过下述三种中的至少一种方式得到:
预配置的;
网络设备广播消息发送的;
网络设备无线资源控制RRC专用信令发送的。
如果上述第一配置信息是网络设备广播消息发送的或网络设备RRC专用信令发送的,则在步骤S102之前,终端设备还可以接收第一配置信息。
本公开各个实施例中提到的Mode 1是指网络设备调度模式。对于Mode 1,终端设备可以通过接收网络设备发送的系统广播信令等途径,获取Mode 1的副链路控制信道(Physical Sidelink Control Channel,PSCCH)资源池配置和关联的副链路共享信道(Physical Sidelink Shared Channel,PSSCH)资源池配置。当终端设备存在待传数据时,其通过缓存状态上报(Buffer Status Report,BSR)向网络设备申请专用的Mode 1通信资源。
本公开各个实施例中提到的Mode 2是指终端设备自主模式。对于Mode 2,终端设备通过接收网络设备系统广播信令获取Mode 2的PSCCH资源池配置和关联的PSSCH资源池配置,或通过网络设备RRC专用信令获取Mode 2的PSCCH资源池配置和关联的PSSCH资源池配置,或通过预配置信息确定Mode 2的PSCCH资源池配置和关联的PSSCH资源池配置,在每个PSCCH周期,终端设备随机选择PSCCH和关联PSSCH的发送资源。
本公开的一些实施例提供的SL传输方法,终端设备可以根据配置信息进行相关配置,进而在SL传输时能够同时工作在Mode 1和Mode 2。终端设备的资源分配模式多样,能够提高SL传输的资源利用效率,便于满足不同的QoS需求。
对于上述提到的提高SL传输的资源利用效率,由于相关技术中,终端设备仅支持单一的一种资源分配模式,不能够充分地利用通信资源,尤其是在 有SL通信场景下,大量的业务数据、或类型较多的业务数据需要传输时,上述缺点将会更加明显。
本公开的一些实施例提供的SL传输方法,终端设备通过配置信息进行配置之后,即可支持同时工作在Mode 1和Mode 2,便于充分利用SL资源。同时,还可以根据业务的服务质量QoS或业务类型等,确定业务与Mode 1或Mode 2的对应关系,便于满足不同的QoS需求。
上述第一配置信息可以用来指示终端设备进行Mode 1和Mode 2同时工作的相关配置,可选地,以上述实施例为基础,上述第一配置信息可以包括下述五种中的至少一种:
1)SL传输时使用的SL逻辑信道标识与SL逻辑信道组标识的映射关系,通常,一个SL逻辑信道组标识与多个SL逻辑信道标识呈映射关系。
2)Mode类型与SL逻辑信道标识的映射关系,该处的Mode类型包括Mode 1和Mode 2中的至少一种,具体地,Mode类型与SL逻辑信道标识的映射关系可以是下述三种情况:Mode 1与SL逻辑信道标识的映射关系;或Mode 2与SL逻辑信道标识的映射关系;或Mode 1与SL逻辑信道标识的映射关系以及Mode 2与SL逻辑信道标识的映射关系。
3)Mode类型与SL逻辑信道组标识的映射关系,该处的Mode类型也包括Mode 1和Mode 2中的至少一种,具体地,Mode类型与SL逻辑信道组标识的映射关系可以是下述三种情况:Mode 1与SL逻辑信道组标识的映射关系;或Mode 2与SL逻辑信道组标识的映射关系;或Mode 1与SL逻辑信道组标识的映射关系以及Mode 2与SL逻辑信道组标识的映射关系。
通过上述2)或3)的实现方式,在终端设备同时工作在Mode 1和Mode 2的情况下,还可以进一步将Mode 1对应的逻辑信道或逻辑信道组,与Mode 2对应的逻辑信道或逻辑信道组进行区分。
4)Mode类型与副链路无线承载标识(SideLink Radio Bearer IDentity,SLRB ID)的映射关系。该处的Mode类型包括Mode 1和Mode 2中的至少一种,具体地,Mode类型与SLRB ID的映射关系可以是下述三种情况:Mode 1与SLRB ID的映射关系;或Mode 2与SLRB ID的映射关系;或Mode 1与SLRB ID的映射关系以及Mode 2与SLRB ID的映射关系。
该实施方式通过建立Mode类型与SLRB ID的映射关系,在终端设备同时工作在Mode 1和Mode 2的情况下,可以根据业务的服务质量QoS和业务类型中的至少一种,确定业务与Mode 1或Mode 2的对应关系,也即该实施方式能够支持不同类型的业务数据发送使用不同的资源分配模式(即Mode 1或Mode 2)。
5)Mode类型与目的标识(Destination ID)的映射关系。该处的Mode 类型包括Mode 1和Mode 2中的至少一种,具体地,Mode类型与Destination ID的映射关系可以是下述三种情况:Mode 1与Destination ID的映射关系;或Mode 2与Destination ID的映射关系;或Mode 1与Destination ID的映射关系以及Mode 2与Destination ID的映射关系。
该实施方式通过建立Mode类型与Destination ID的映射关系,同样可以根据业务的服务质量QoS和业务类型中的至少一种,确定业务与Mode 1或Mode 2的对应关系,也即该实施方式能够支持不同类型的业务数据发送使用不同的资源分配模式(即Mode 1或Mode 2)。
以上述多个实施例为基础,终端设备同时工作在Mode 1和Mode 2的情况下:
可选地,如图2和图3所示,对于进行SL通信的终端设备(UE1和UE2)而言,Mode 1和Mode 2可以共享一个媒介访问控制MAC实体。
进一步可选,如图2和图4所示,对于进行SL通信的终端设备(UE1和UE2)而言,Mode 1和Mode 2还可以分别对应不同的MAC实体。
在图2至图4所示的实施例中,第一配置信息中还可以包括有Mode类型与SLRB ID的映射关系。
以下将分Mode 1和Mode 2共享MAC实体,以及Mode 1和Mode 2分别对应不同MAC实体的两种情况分别进行介绍。
在图2和图3所示的实施例中,进行SL通信的终端设备(例如,UE1和UE2)可以分别创建一个MAC实体,UE1和UE2的mode 1和mode 2同时工作时,共享一个MAC实体。即在图3中,UE1的mode 1和mode 2同时工作时共享MAC1;UE2的mode 1和mode 2同时工作时共享MAC2。
上述仅仅以UE1和UE2之间的SL通信为例进行介绍,如图2所示,对 于UE1和UE3之间的SL通信、UE1和UE4之间的SL通信等等,本公开各个对应的实施例介绍的内容同样适用,在此不再重复描述。
在Mode 1和Mode 2共享MAC实体的情况下,前文几个实施例的步骤S102中提到的根据第一配置信息进行配置还可以包括:定义Mode 1和Mode 2共享的MAC实体执行下述至少一种行为:
1)如果当前配置的SL逻辑信道(可以是全部的SL逻辑信道)中没有缓存数据,则在有数据到达的SL逻辑信道(可以是上述当前配置的SL逻辑信道中的一个或多个)与所述Mode 1对应的情况下,触发副链路缓存状态报告SL BSR。
该实施方式中,第一配置信息中可以包括有Mode类型与SL逻辑信道标识的映射关系。
2)如果当前配置的SL逻辑信道(可以是全部的SL逻辑信道)中的至少一个中具有缓存数据,则在有数据到达的SL逻辑信道(可以是上述当前配置的SL逻辑信道中的一个或多个)具有更高的逻辑信道优先级、且所述有数据到达的SL逻辑信道与所述Mode 1对应的情况下,触发SL BSR。
该实施方式中,第一配置信息中可以包括有Mode类型与SL逻辑信道标识的映射关系。
该实施方式中提到的“有数据到达的SL逻辑信道具有更高的逻辑信道优先级”,也即:当前有数据到达的SL逻辑信道的优先级,高于当前配置的SL逻辑信道中、具有缓存数据的SL逻辑信道的优先级。
3)如果重传SL BSR定时器超时,在当前配置的SL逻辑信道(可以是全部的SL逻辑信道)中的至少一个中具有缓存数据、且所述重传SL BSR定时器对应的SL逻辑信道与所述Mode 1对应的情况下,触发SL BSR。
该实施方式中,第一配置信息中可以包括有Mode类型与SL逻辑信道标识的映射关系。
通过上述多种实施方式,在满足SL BSR触发条件时能够及时触发SL BSR,以及时向网络设备请求Mode 1传输所需要的资源,提高通信效率。
同时,仅仅在与Mode 1对应的逻辑信道中到达缓存数据的情况下才触发SL BSR,在与Mode 2对应的逻辑信道中到达缓存数据的情况则不触发 SL BSR。
可选地,在Mode 1和Mode 2共享MAC实体的情况下,前文几个实施例的步骤S102中提到的根据第一配置信息进行配置还可以包括:定义Mode 1和Mode 2共享的MAC实体执行下述行为:
在计算SL BSR的BS域指示的缓存大小时,忽略目标SL逻辑信道中的缓存数据;
其中,所述目标SL逻辑信道包括下述至少一种:与所述Mode 2对应的SL逻辑信道;与所述Mode 2对应的目的标识对应的SL逻辑信道。
通过上述实施方式,能够忽略Mode 2对应SL逻辑信道中的缓存数据,仅仅将Mode 1对应的SL逻辑信道中的缓存数据计算进SL BSR,使Mode 1和Mode 2能够独立工作,互不影响。
在Mode 1和Mode 2共享MAC实体的情况下,可选地,终端设备还可以进行资源分配模式的灵活切换,具体地,终端设备可以根据第二配置信息进行配置,使得所述终端设备仅仅工作在Mode 1或Mode 2,也即取消同时工作在Mode 1和Mode 2。
上述第二配置信息也可以通过下述至少一种方式得到:
预配置的;
网络设备广播消息发送的;
网络设备无线资源控制RRC专用信令发送的。
可选地,上述根据第二配置信息进行配置可以包括:定义Mode 1和Mode 2共享的MAC实体执行下述至少一种行为:
1)取消被触发的SL BSR;
2)取消被触发的调度请求SR,其中,所述SR由SL BSR触发;
3)停止或重启重传SL BSR定时器;
4)停止或重启周期SL BSR定时器。
通过上述多种实施方式,终端设备由同时工作在Mode 1和Mode 2、转换进入Mode 1或Mode 2之后,特别是进入Mode 2之后,可以及时取消或停止之前的相关配置,进而还可以在Mode 1或Mode 2工作时进行重新配置,避免因资源分配模式切换后造成的配置影响,提高通信有效性。
如图2和图4所示,对于进行SL通信的终端设备(UE1和UE2)而言,Mode 1和Mode 2还可以分别对应不同的MAC实体。该实施例中,进行SL通信的一对终端设备(UE1和UE2)可以分别创建一对MAC实体,见图4,UE1的mode 1工作在MAC11,mode 2工作在MAC12;UE2的mode 1工作在MAC21,mode 2工作在MAC22。
在Mode 1和Mode 2分别对应不同的MAC实体的情况下,前文几个实施例的步骤S102中提到的根据第一配置信息进行配置还可以包括:基于第一配置信息得到终端设备的最大发送功率P_max;Mode 1对应MAC实体的最大发送功率P_max1;以及Mode 2对应MAC实体的最大发送功率P_max2。
这样,前文几个实施例的步骤S102中提到的根据第一配置信息进行配置还可以包括:如果所述P_max大于所述P_max1和所述P_max2之和,则定义Mode 1对应的MAC实体和Mode 2对应的MAC实体执行下述四种中的一种行为:
1)将剩余功率分配给所述Mode 1对应的MAC实体,或将剩余功率分配给所述Mode 2对应的MAC实体。
该处的剩余功率,可以由P_max与P_max1和P_max2的差值得到。
2)根据第一预设比例,将剩余功率分配给所述Mode 1对应的MAC实体和所述Mode 2对应的MAC实体。
该实施方式可以预先存储有上述第一预设比例,具体例如,第一预设比例可以是5:5或6:4等等。
3)根据待传数据的优先级与第一预设阈值的大小关系,将剩余功率分配给所述Mode 1对应的MAC实体或所述Mode 2对应的MAC实体。
具体例如,如果待传数据的优先级大于或等于第一预设阈值,则将剩余功率分配给mode 1对应的MAC实体;如果待传数据的优先级小于第一预设阈值,则将剩余功率分配给mode 2对应的MAC实体。
该实施方式中,可选地,可以采用将剩余功率分配到的MAC实体来传输上述待传数据。
4)根据与所述Mode 1对应的待传数据的优先级P 1,以及与所述Mode 2对应的待传数据的优先级P 2的大小关系,将剩余功率分配给所述Mode 1对 应的MAC实体或所述Mode 2对应的MAC实体。
具体例如,如果P 1大于或等于P 2,则将剩余功率分配给mode 1对应的MAC实体;如果P 1小于P 2,则将剩余功率分配给mode 2对应的MAC实体。
可选地,如果P_max小于P_max1和P_max2之和,则定义Mode 1对应的MAC实体和Mode 2对应的MAC实体执行下述四种中的一种行为:
1)根据所述P_max与所述P_max1和所述P_max2之差,降低所述P_max1或降低所述P_max2。
