Description

半静态传输方法及装置 技术领域
本申请涉及数据传输技术领域,尤其涉及一种半静态传输方法及装置。
背景技术
V2X通信泛指车辆与车辆(英文:Vehicle to Vehicle,简称:V2V)、车辆与基础设施(英文:Vehicle-to-Infrastructure,简称:V2I)以及车辆与行人(英文:Vehicle-to-Infrastructure,简称:V2P)之间的通信。V2X通信本质上是一种在车辆之间进行数据传输和信息交互的通信技术。由于V2X通信事关车辆行驶安全的关键信息,其需要及时、准确地进行信息交互,因而具有“高可靠、短时延”的通信需求。另一方面,作为现有全球主流的无线通信技术,第三代合作伙伴计划(英文:3rd Generation Partner Project,简称:3GPP)长期演进(英文:Long Term Evolution,简称:LTE)蜂窝通信具有时延短、容量大、速度快及可靠性高等优势,因此可以考虑利用LTE蜂窝系统支持V2X通信,以实现良好的V2X通信性能。
鉴于此,标准化组织3GPP(3rd Generation Partner Project)已经开始着手进行“基于LTE的V2X通信(LTE-based V2X,LTE-V2X)”标准化工作,旨在基于LTE蜂窝通信系统、充分利用LTE的优势,有效支持与道路安全相关的车辆无线通信。
在基于LTE-V2X通信系统中,为了降低V2X通信可能带来的下行物理控制信道(英文:Physical Downlink Control Channel,简称:PDCCH)调度开销,3GPP LTE-V2X标准采用半静态调度(英文:Semi-persistent Scheduling,简称:SPS)技术为车辆用户终端(英文:User Equipment,简称:UE)分配传输资源。
在LTE-V2X中,基于SPS技术为UE分配半静态传输资源包括:基站通过PDCCH为UE分配SPS资源,之后UE即可周期性地使用所分配的SPS资源。特别地,在时域上每一次SPS资源出现的时刻,称为一次“SPS传输机会”,在每一次传输机会上,UE即可利用相应的传输资源传输数据。
可见,在LTE-V2X的上行SPS中,基站只需一次性地指示上行SPS调度信息,UE即可周期性地在分配的SPS资源上传输上行数据,从而节省基站上行调度开销。现有的此种SPS调度方法,支持基于IP的语音业务(英文:Voice over IP,简称:VoIP) 这类到达周期固定的周期性业务数据的传输,并且在现有的SPS调度机制中,仅支持一路SPS资源的调度,而在实际的V2X通信中,具有诸如协同感知消息(英文:Cooperative Awareness Message,简称:CAM)、分散环境通知消息(英文:Decentralized Environmental Notification Message,简称:DENM)、后向建立消息(英文:Backward Set-up Message,简称:BSM)等不同的消息类型,不同种类的V2X往往具有不同的业务达到周期,现有的SPS调度方案难以支持各种类半静态业务数据的调度。

附图说明
为了更清楚地说明本申请的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,对于本领域普通技术人员而言,在不付出创造性劳动性的前 提下,还可以根据这些附图获得其他的附图。

具体实施方式
本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案,并不构成对于本发明实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本发明实施例提供的技术方案对于类似的技术问题,同样适用。
图1是本发明的一种可能的应用场景示意图。如图1所示,该场景中包括接入设备和多个UE,接入设备用于为各个UE分配半静态传输资源,UE之间通过D2D直通技术进行数据传输和信息的交互。在图1所示场景中,UE与UE之间进行数据直接通信的链路称为直通链路(英文:Sidelink,简称:SL)。
图2是本发明的另一种可能的应用场景示意图。如图2所示,各个UE均与接入设备连接,UE之间的数据通信需要接入设备的中转,其中,UE向接入设备发送数据的无线链路称为上行链路(英文:Uplink,简称:UL),接入设备向UE发送数据 的无线链路称为下行链路(英文:Downlink,简称:DL)。
本发明实施例提供的半静态传输方法不仅适用于图1和图2所示的应用场景中,也可以应用于其它包括SL和UL的通信系统中。
本发明涉及到的UE主要是在V2X中涉及到的终端设备,如车载终端,当然该UE还可以是各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,简称UE),移动台(Mobile station,简称MS),终端(terminal),终端设备(Terminal Equipment)等等。为方便描述,本申请中,上面提到的设备统称为用户设备或UE。
本发明所涉及的接入设备是接入网中的设备,如基站。本发明所涉及到的基站(base station,简称BS)是一种部署在无线接入网中用以为UE提供无线通信功能的装置。所述基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备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简称:eNB或者eNodeB),在第三代3G网络中,称为节点B(Node B)等等。为方便描述,本申请中,上述为UE提供无线通信功能的装置统称为基站或BS。本发明中的网络设备包括上述接入设备,可以包括核心网设备,如移动管理实体(英文:Mobility Management Entity,简称:MME),数据网关等。
在现有的上行半静态调度传输技术中只能支持一路半静态传输资源,无法适应多路业务数据传输的需求,即使按照现有半静态调度制度为UE配置了多路半静态传输资源,也可能会发生业务传输混乱的情况,例如,在UE中配置的SPS1资源与业务1的周期相匹配,SPS2资源与业务2相匹配,UE在传输业务1和业务2时,可能会出现业务1抢占SPS2资源以及业务2抢占SPS1资源的情况发生。
为了解决现有技术中存在的上述问题,本发明实施例提供了一种半静态传输方案,该半静态传输方案支持UE中一路或多路半静态传输的配置,其中在本发明方案中半静态传输资源与逻辑信道之间具有对应关系,并且在数据传输时确保在传输资源中传输与该传输资源对应的逻辑信道中的数据,进而避免因为逻辑信道间数据复用和传输顺序不当导致的传输失败、丢包和半静态传输资源浪费等问题。
在本申请中,所涉及的“对应关系”可以看做是一种“绑定关系”,“对应”可以看做是一种“绑定”,例如半静态传输资源与逻辑信道之间具有对应关系,可以看做半静态传输资源与逻辑信道绑定,半静态传输资源与逻辑信道信道之间具有绑定关 系。
以下将结合附图对本发明实施例的半静态传输方法进行详细说明。
图3是本发明实施例一半静态传输方法的流程图。图3所示方法在诸如图1所示的包括SL的通信系统中执行,例如LTE-V2X场景中,图1所示方法包括:
S101,UE1向eNB发送终端能力报告,该终端能力报告中携带UE1是否支持多个SPS配置的指示信息。
在图1所示的场景中,终端能力报告中的指示信息用于指示UE是否支持基于直通链路(Sidelink)的多个SPS配置。
现有3GPP LTE协议版本在Sidelink上并不支持并行多个SPS配置的机制,基于现有协议版本(Rel-13及之前版本)的UE也可能无法支持该技术。因而,UE需要在现有LTE协议的基础上,按照本发明的技术方案,对UE功能进行增强后,才能支持并行多个SPS配置机制。
鉴于此,UE需要通过此步骤向eNB上报其是否具有能力支持基于Sidelink的多个并行SPS配置的机制,以辅助eNB进行SPS配置及激活的相应决策。
若UE上报的终端能力无法支持并行多SPS配置机制,则eNB将按照现有LTE版本的sidelink通信技术,为其进行资源调度调度;若UE所上报的终端能力指示UE支持基于Sidelink的并行多SPS配置机制,则UE和eNB执行下述步骤。
步骤102,UE1向eNB发送终端辅助信息。
UE1通过终端辅助信息向eNB上报其SL逻辑信道的业务特性,以请求eNB为相应SL逻辑信道的业务数据进行SL SPS配置和/或激活。其中在图1所示的场景中,UE1上报的终端辅助信息指示基于SL逻辑信道的业务特性。
可选的,在终端辅助信息中包括至少一个SL逻辑信道的业务特性信息,每个SL逻辑信道的业务特性信息包括但不限于以下一个参数或多个参数的组合:逻辑信道标识LCID、层2目标地址、数据包到达周期、数据包到达时刻、数据包大小和数据包优先级;所述数据包优先级可以是:临近业务数据包优先级(英文:ProSe Per-Packet Priority,PPPP)。上述业务特性信息中所包括的参数仅作为示例,本发明对每个SL逻辑所对应业务特性信息包含的参数不做具体限制。
业务特性信息的上述参数中,LCID和层2目的地址可以唯一标识和确定一个SL 逻辑信道;每个SL逻辑信道所对应的PPPP,标示该SL逻辑信道的优先级,且eNB可以通过PPPP获得相应SL逻辑信道中、业务数据时延要求、可靠性要求等服务质量(QoS)需求;数据包到达周期,可以设置一个特殊取值,例如“Inf”,标识相应的业务数据包到达为“非周期”。
可选的,UE1向eNB发送所述终端辅助信息的触发条件可以是:当UE1确定一个或多个SL逻辑信道中有业务数据到达,且所述业务数据是周期性到达时UE1向eNB发送终端辅助信息;或,UE1确定一个或多个SL逻辑信道中的数据的到达周期发生改变,包括从一个周期变成另一个周期,或者工周期性到达变成非周期的,此处对于UE的实现方法不做具体限制。
UE获得每个SL逻辑信道中数据包到达周期的实现方法可以是:对于某逻辑信道,UE可以为其设置一个计数器、记录每个数据包的到达间隔,当最近M次的数据包到达间隔都相等,则将所述到达间隔认为是数据包到达周期;或,当最近M次的数据包到达间隔的方差小于某一门限值,则将所述到达间隔的平均值作为该SL逻辑信道的数据包到达周期。此处,UE获得数据包到达周期的方法,取决于UE的实现,此处不做具体限定。
可选的,本步骤中所述的终端辅助信息,可以通过RRC专用消息、也可以通过媒体接入控制协议(英文:Medium Access Control,简称:MAC)层控制单元(MAC CE),由UE1发送给eNB。
步骤S103,eNB向UE1发送SL SPS配置信息。
可选的,eNB通过通过RRC专用消息,向UE1发送SL SPS配置信息,其中可包括并行多个SL SPS配置信息,每个SL SPS配置信息对应一个SL SPS配置。
可选的,eNB向UE1发送的每个SL SPS配置的配置信息包括但不限于下述一个或多个参数的组合:SPS ID、SPS间隔、调制与编码策略(英文:Modulation and Coding Scheme,简称:MCS)、LCID、层2目的地址、PPPP。上述SL SPS配置信息中所包括的参数仅作为示例,本发明对每个SL SPS配置信息包含的参数不做具体限制。
其中,每个SL SPS配置信息中SPS ID唯一标识一个具体的SL SPS配置及相应的一组配置参数。对于一个具体的SL SPS配置,当其包含LCID和层2目标地址时,LCID和层2目标地址将唯一指示一个SL逻辑信道。
本步骤中,eNB可以针对终端辅助信息中上报的相应SL逻辑信道的业务特性(如 数据包到达周期、数据到达时刻、数据包大小),为UE1配置与该SL逻辑信道业务特性相匹配的SL SPS配置参数,包括SPS ID,SPS间隔,MCS,以及(可选的)标识该SL逻辑信道的LCID和层2目的地址,并发送给UE1。具体如何根据业务特性、设置SPS ID、SPS间隔、MCS等参数的值,取决于eNB算法实现,此处不做具体限定。
此外,UE1会将此步骤中所接收到的SL SPS配置信息、覆盖其此前可能接收的、具有相同SPS ID的SL SPS配置信息;而如果UE1所接收到的SL SPS配置信息所对应的SPS ID,与已有SL SPS配置的SPS ID都不相同,则UE1会在已有SL SPS配置的基础上,另行存储本步骤中所接收的这些SL SPS配置。
步骤S104,eNB向UE1发送SPS激活消息。
UE1利用eNB发送的SPS激活消息激活相应的SL SPS配置,并且为激活的SL SPS配置指示SL SPS传输资源,进一步UE1还将激活的SL SPS配置及相应的SL SPS传输资源与指定的SL逻辑信道之间建立对应关系。
可选的,SL SPS激活消息包括下述参数的一个或者多个的组合:SPS ID,SL SPS传输资源,LCID,层2目标地址和SPS类型指示符。
其中,eNB可以按照终端辅助信息中上报的SL逻辑信道的业务特征参数(如,数据包大小),为UE1的该SL逻辑信道分配相应的SL SPS传输资源;具体资源分配方法取决于eNB的算法实现,此处不做限定。
收到此激活消息后,UE1根据激活消息中的SPS ID,激活包含相同SPS ID的SL SPS配置,随后UE1即可以所激活的SL SPS配置中包含的SPS间隔为周期、按照所包含的MCS,周期性地使用eNB所分配的SL SPS传输资源向其它UE,如UE2传输数据。
本步骤中,UE1将激活的SL SPS配置及相应的SL SPS传输资源与指定的SL逻辑信道之间建立对应关系,包括:
(1)如果激活消息中包含了LCID和层2目标地址,LCID和层2目标地址可以唯一标识一个SL逻辑信道,则UE1确定激活消息所指示的半静态传输资源与激活消息中的LCID和层2目标地址所确定的逻辑信道之间的对应关系。
(2)如果每个SL SPS配置信息均包含了LCID和层2目标地址,LCID和层2目标地址可以唯一标识一个SL逻辑信道,则UE1确定所激活的半静态资源配置和激 活消息消息所指示的半静态传输资源,与SL SPS配置信息中的LCID和层2目标地址所确定的逻辑信道之间的对应关系.
(3)如果激活消息中包含了LCID和层2目标地址,LCID和层2目标地址可以唯一标识一个SL逻辑信道,则UE1确定所激活的半静态资源配置与激活消息中的LCID和层2目标地址所确定的逻辑信道之间的对应关系。
总而言之,无论是上述哪种方式,UE1会根据SL SPS配置信息或激活消息中所携带的LCID和层2目标地址,将所激活的SL SPS配置及其对应的SL SPS传输资源与指定的SL逻辑信道之间具有对应关系。
可选的,所述SPS类型指示符可以是1bit标识,用于区分所激活的SL SPS配置的类型,例如该指示符设置为“1”时、标识所激活的SPS配置为SL SPS配置,而设置为“2”时标识为UL SPS配置。
可选的,所述激活消息具体可以通过下行控制信息(DCI)由eNB发送给UE1。
对于本步骤中所激活的SL SPS配置,如果在执行本步骤之前,UE1已经激活了与其具有相同SPS ID的SL SPS配置、并分配了相应SL SPS传输资源,那么在收到本步骤中的激活消息后,UE1将首先去激活当前已激活SL SPS配置、释放相应的SL SPS传输资源,再按照本步骤中的激活消息,重新激活相应的SL SPS配置、使用其对应SL SPS传输资源传输数据。否则,UE1则可以在已激活的其他SL SPS配置的基础上,并行激活本步骤的SL SPS配置,并使用各SL SPS配置相应的多路SPS资源数据传输。
可选的,如果要eNB根据步骤S103的UE1终端辅助信息上报,需要激活多个SL SPS配置,则可以通过向UE1发送多个SL SPS激活消息来实现。
在本步骤之后,UE1可能激活多路SL SPS配置、分别对应于多路并行的SL SPS传输资源,而所激活的每个SL SPS配置及相应SL SPS传输资源均会与指定SL逻辑信道对应。
步骤S105,对于所激活的SL SPS配置,UE1在相应SL SPS资源上传输与其具有对应关系的SL逻辑信道中的数据。
对于所激活的SL SPS配置对应的SL SPS传输资源,UE1将按照如下方法将SL SPS资源分配给SL逻辑信道,进而将个逻辑信道的数据复用到MAC PDU中。
当SL逻辑信道中待传输数据量大于与其对应的SL SPS传输资源所能容纳的数 据量时,UE1优先为所述SL SPS配置所对应的SL逻辑信道中的待传数据分配资源,直到所有的SL SPS传输资源被用尽;当SL SPS传输资源足够容纳与其对应的SL逻辑信道中的所有数据传输时,UE1为所对应的SL逻辑信道中的所有待传数据都分配足够的传输资源。
进一步,如果所述SL SPS传输资源没有被占满,则按照现有的LTE协议中,Sidelink通信的逻辑信道优先级处理(Logical Channel Prioritization Procedure)方法,为其它SL逻辑信道中的数据分配资源。
按照上述方法处理后,UE1将按照每个SL逻辑信道将按照其所分配资源大小、确定其所能复用的数据量,并据此将相应SL逻辑信道的业务数据复用到MAC PDU中,并将其通过SL SPS传输资源进行Sidelink传输。
由于上述步骤中,所激活SL SPS配置对应的SPS传输中源被优先分配给了其所对应的SL逻辑信道,因此本步骤可以保证每个所激活的SL SPS配置,其SL SPS传输资源均会用于传输其所对应的SL。
对于每个已经激活的SL SPS配置,其所对应SPS资源将周期性重现;因此在每次出现的SL SPS传输资源上,UE1均会采用上述方法在SL逻辑信道上分配资源,确定每个SL逻辑信道能够传输的数据量,并完成待传数据的复用。
本发明实施例方案,将激活的SPS配置与相应逻辑信道进行对应,并且通过改进现有MAC层的数据复用流程,确保数据传输性能,避免激活并行多路SPS配置后,因数据复用和传输顺序不当,而产生的潜在丢包/资源浪费的问题。

步骤S202,eNB向UE1发送SL SPS配置信息。
本步骤中eNB可以将所有可能的SL SPS配置信息,一次性配置给UE1。其中,每个SL SPS配置信息所包含的参数(如SPS ID、SPS间隔、MCS、LCID等)所有可能的取值,可以是标准协议的规定,或eNB所属运营商的配置、或eNB生产商的设置,此处不做具体限定。而UE1所对应的层2目标地址的可能取值,将按照现有技术,由UE1上报给eNB。
步骤S203,UE1向基站发送终端辅助信息。
本步骤中,UE1可以按照实施例一中配置终端辅助信息的方式,向eNB上报其SL逻辑信道的业务特性,以请求eNB为相应SL逻辑信道的业务数据进行SL SPS配置和/或激活。
步骤S204,eNB向UE1发送SPS激活消息。
UE1利用UE1发送的SPS激活消息激活相应的SL SPS配置,所述激活消息还用于为激活的SL SPS配置指示SL SPS传输资源,进一步UE1还将激活的SL SPS配置及相应的SL SPS传输资源与指定的SL逻辑信道进行对应。
步骤S205,对于所激活的SL SPS配置,UE1在相应SL SPS资源上传输与其具有对应关系的SL逻辑信道中的数据。
本发明实施例二方法实现的各个步骤可以参见实施例一,本实施例二与实施例一方法的区别仅在于,实施例一在将终端辅助信息发送给eNB之后接收eNB发送的配SPS配置信息,而在实施例二中eNB先将所有可能的SPS配置信息发送给UE1,之后UE1向eNB发送终端辅助信息以请求eNB激活UE1所指定的一个或多个SPS配置。
图5是本发明实施例三半静态传输方法的流程图。图5所示方法在诸如图1所示的包括SL的通信系统中执行,包括:
步骤301,UE1确定SL传输资源池配置信息。
UE1根据SL传输资源池配置信息确定网络设备分配的SL传输资源池以及该传输资源池包含的资源。具体的,SL传输资源池包括用于SL数据传输的“时-频”资源的集合。
可选的,UE1通过eNB获取SL传输资源池配置信息,例如eNB可以通过系统信息广播或者RRC专用消息,向UE1发送SL传输资源池配置信息。
可选的,UE1也可以根据协议的相关规定和/或运营商的频谱规划等因素,由终端厂商预先配置在UE中。
步骤302,UE1根据自身SL逻辑信道中的业务特性,在上述SL传输资源池中,自行选择半静态传输资源、自行确定相应的SL SPS配置信息,并且将自行选择的半静态传输资源和/或SL SPS配置信息与相应的SL逻辑信道之间建立对应关系。
可选的,本步骤中UE1自行选择半静态传输资源、确定相应SL SPS配置信息的触发条件,可以与实施例一中UE1确定向eNB发送终端辅助信息的触发条件相同。
其中,UE1将针对其相应SL逻辑信道的业务特征(数据包到达周期、数据到达时刻、数据包大小),自行确定与该SL逻辑信道业务特性相匹配的SL半静态资源配置参数UE1将根据其相应SL逻辑信道中的业务特性,自行确定相应的半静态资源配置。可选的,所述的UE自行确定的半静态资源配置所包含的参数可以是下述参数的任意组合:SPS ID,SPS间隔,MCS,LCID,层2目的地址等。具体如何根据业务特性、设置SPS ID、SPS间隔、MCS等参数的值,取决于UE算法实现,此处不做具体限定。
可选的,UE1为所述SL逻辑信道选择所述半态传输资源的方法,可以是UE1在所述SL传输资源池中随机选择具体资源,或者UE1根据其对SL资源池中资源负载检测结果,选择当前SL传输资源池中、空闲的资源。此处具体资源选择方法取决于UE算法实现,此处不做具体限定。
在为其SL逻辑信道配置相应的半静态资源配置并选择了半静态传输资源后,UE将所述的版静态传输资源与相应的SL逻辑信道进行“对应”,即确定所述半静态传输资源与相应SL逻辑信道的对应关系
步骤303,UE1将在所选择的SL半静态传输上进行数据复用,并利用相应的SL半静态传输资源,传输与其具有对应关系的SL逻辑信道中的数据。
本步骤的具体内容,与上述实施例一中的步骤S105相同,不再赘述。
图6是本发明实施例四半静态传输方法的流程图。图6所示方法在诸如图2所示的包括UL的通信系统中执行,例如LTE-V2X场景中,图6所示方法包括:
S401,UE1向eNB发送终端能力报告,该终端能力报告中携带UE1是否支持并行的多个SPS配置的指示信息。
在图2所示的场景中,所述指示信息用于指示UE是否支持基于UL的并行多个SPS配置。
S402,UE1向eNB发送终端辅助信息。
UE1通过终端辅助信息向eNB上报其UL逻辑信道的业务特性,以请求eNB为相应UL逻辑信道的业务数据进行UL SPS配置和/或激活。其中在图1所示的场景中,UE1上报的终端辅助信息指示基于UL逻辑信道的业务特性。
可选的,在终端辅助信息中可以包括一个或多个UL逻辑信道的业务特性信息,每个UL逻辑信道对应的业务特性信息包括但不限于以下一个参数或多个参数的组合:所述UL逻辑信道对应的LCID(逻辑信道标识)、数据包到达周期、数据包到达时刻、数据包大小等。上述业务特性信息中所包括的参数仅作为示例,本发明对每个SL逻辑所对应业务特性信息包含的参数不做具体限制。
业务特性信息的上述参数中,LCID可以唯一标识和确定一个UL逻辑信道;由于UL逻辑信道是eNB为UE配置的,因此eNB本身知道UE每个LCID相应的逻辑信道中、业务数据的时延要求、可靠性要求等服务质量(QoS)需求。
步骤403,eNB向UE1发送UL SPS配置信息。
可选的,eNB通过RRC专用消息,向UE1发送UL SPS配置信息,其中可包括并行多个UL SPS配置,每个UL SPS配置信息对应一个UL SPS配置。
可选的,eNB向UE1发送的每个UL SPS配置的配置信息包括但不限于下述一个或多个参数的组合:SPS ID、SPS间隔、LCID。此处对每个UL SPS配置所包括的配置信息不做具体限制。
其中,每个UL SPS配置信息中的SPS ID唯一标识一个具体的UL SPS配置及相应的一组配置参数。对于一个具体的SPS配置,当其包含LCID时,LCID唯一指示一个UL逻辑信道。
步骤404,eNB向UE1发送SPS激活消息。
UE1利用eNB发送的SPS激活消息激活相应的UL SPS配置,并且为激活的UL SPS配置指示UL SPS传输资源,进一步UE1还将激活的UL SPS配置及相应的UL SPS传输资源与指定的UL逻辑信道进行对应。
可选的,UL SPS激活消息包括下述参数的一个或者多个的组合:SPS ID,SL SPS传输资源,LCID,SPS类型指示符。

收到此激活消息后,UE1根据激活消息中的SPS ID,激活包含相同SPS ID的UL SPS配置,随后UE1即可以所激活的UL SPS配置中包含的SPS间隔为周期、按照所包含的MCS,周期性地使用eNB所分配的UL SPS传输资源向其它UE,如UE2 传输数据。
本步骤中,UE1将激活的UL SPS配置及相应的UL SPS传输资源与指定的UL逻辑信道进行对应,包括:
(1)如果激活消息中包含了LCID,LCID可以唯一标识一个UL逻辑信道,则UE1确定激活消息所指示的半静态传输资源与激活消息中的LCID所确定的逻辑信道之间的对应关系。
(2)如果每个UL SPS配置信息均包含了LCID,LCID可以唯一标识一个UL逻辑信道,则UE1确定所激活的半静态资源配置和激活消息消息所指示的半静态传输资源,与UL SPS配置信息中的LCID所确定的逻辑信道之间的对应关系.
(3)如果激活消息中包含了LCID,LCID可以唯一标识一个UL逻辑信道,则UE1确定所激活的半静态资源配置与激活消息中的LCID所确定的逻辑信道之间的对应关系。
总而言之,无论是上述哪种方式,UE1会根据UL SPS配置信息或激活消息中所携带的LCID,将所激活的UL SPS配置及其对应的UL SPS传输资源与指定的UL逻辑信道对应。
另外,可选的,本实施例中允许本步骤所激活的UL SPS配置信息中不包含LCID、且激活消息中也不包括相应的LCID;则在这种情况下,所激活的UL SPS配置及相应的SL SPS传输资源,将不与任何UL逻辑信道进行对应。
步骤405,对于所激活的UL SPS配置,UE1在相应UL SPS资源上进行数据复用,并利用相应的UL SPS传输资源,传输所对应的UL逻辑信道中的数据。
本步骤中与实施例一中的S105实现方法相同,不再赘述。另外,若在上述步骤S404中,所激活的UL SPS配置及相应的UL SPS传输资源没有与任何的UL逻辑信道对应,则在该UL SPS传输资源上,UE将直接沿用现有LTE协议中UL的逻辑信道优先级处理方法,对各个UL逻辑信道中的数据进行复用,并将复用后所封装的MAC PDU通过所述UL SPS资源进行数据传输。除此之外,本实施例的各步骤的实现方法与实施例一对应相同,不再赘述。
图7是本发明实施例五半静态传输方法的流程图。图7所示方法在诸如图2所示的包括UL的通信系统中执行,例如LTE-V2X场景中,图7所示方法包括:
步骤S501,UE1向基站发送终端能力报告,该终端能力报告中携带UE1是否支 持并行的多个UL SPS的指示信息。

步骤S505,对于所激活的UL SPS配置,UE1在相应UL SPS资源上传输与其具有对应关系的UL逻辑信道中的数据。
本发明实施例二方法实现的各个步骤可以参见实施例四,本实施例五与实施例四方法的区别仅在于,实施例四在将终端辅助信息发送给eNB之后接收eNB发送的配SPS配置信息,而在实施例五中eNB先将所有可能的SPS配置信息发送给UE1,之后UE1向eNB发送终端辅助信息以请求eNB激活UE1所指定的一个或多个SPS配置。
