一种传输处理方法、装置及终端
相关申请的交叉引用
本公开主张在2021年03月29日在中国提交的中国专利申请号No.202110334348.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种传输处理方法、装置及终端。
背景技术
车对外界的信息交换(vehicle to everything，V2X)技术借助车-车，车与路测基础设施、车与路人之间的无线通信，可实时感知车辆周边状况、共享道路信息并进行及时预警，已成为当前世界各国解决道路安全问题的一个研究热点。
在相关的长期演进(Long Term Evolution，LTE)V2X技术中，在用户设备(User Equipment，UE)与UE之间传输数据的PC5接口(也称之为直通链路(sidelink，SL))广播通信已经可以支持基本的基于道路安全的业务的传输。而随着车联网技术的进一步发展，新空口(New Radio，NR)V2X现阶段相比LTE V2X，出现新的一些应用场景，例如：车辆编队、高级驾驶、传感器信息共享、以及远程控制等应用。对应于NR V2X单播、组播和广播业务。
当V2X UE有业务/媒体介入控制层(Media Access Control，MAC)层控制信息要发送时，如果当前没有可以满足要求的调度资源，会触发调度请求(Scheduling Request，SR)，请求分配资源。UE针对多MAC协议数据单元(Protocol Data Unit，PDU)预留资源时(一般针对周期业务)，会根据混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈属性来设置所预留的资源间隔。但是，当后续HARQ反馈属性发生改变时，有可能出现预留的资源间隔无法满足后续最高优先级的逻辑信道的HARQ反馈属性的情况，造成传输的异常。。
发明内容

为了实现上述目的，本公开实施例提供一种传输处理方法，由终端执行，包括：
确定当前直接通信链路的第一逻辑信道或第一媒体接入控制单元MAC CE对应的混合自动重传请求HARQ反馈属性；

具体实施方式
本公开实施例中术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
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，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。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，都属于本公开保护的范围。
应该知道的是，设备和设备之间的直接通信链路为Sidelink链路，其对应的无线接口称为直接通信接口(也称为Sidelink接口)；网络与直接通信设备之间的蜂窝通信链路称之为Uu链路(Uu link)，其对应的接口称为Uu接口。直接通信示意图如图4所示，终端1(UE1)和终端2(UE2)之间通过Sidelink通信，UE1、UE2可分别与基站(eNodeB)通过Uu link通信，eNodeB可接入核心网。
V2X通信是直接通信的一种，主要包含三方面内容：
车到车(Vechile-to-Vechile，V2V)：车上的车载单元(On Broad Unit，OBU)之间的通信。
车道网络(Vechile-to-Infrastructure，V2I)：车和路侧设备(Road Side Unit， RSU)之间的通信。
车到行人(Vechile-to-Pedestrian，V2P)：车和行人之间的通信。
本公开实施例提供了一种传输处理方法及装置。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1所示，为本公开实施例提供的一种传输处理方法，由终端执行，包括：
步骤101，确定当前直接通信链路的第一逻辑信道或第一媒体接入控制单元(Medium Access Control Control Element，MAC CE)对应的混合自动重传请求HARQ反馈属性；
步骤102，在当前传输的预留资源与确定的HARQ反馈属性未匹配的情况下，进行资源重选。
执行本公开实施例的传输处理方法的终端，按照上述步骤，会针对当前直接通信链路，确定第一逻辑信道或第一MAC CE对应的HARQ反馈属性，从而在当前传输的预留资源与确定的该HARQ反馈属性未匹配的情况下，触发资源重新，避免预留资源和HARQ反馈属性无法匹配时出现的传输异常问题。
这里，进行重新的资源即发送资源。
需要说明的是，执行该实施例的传输处理方法的终端，传输资源采用终端自选资源分配模式进行确定。当前直接通信链路，也可理解为当前直接通信链路进程(SL process)。
该实施例中，可选地，所述预留资源是MAC层针对多MAC PDU进行资源选择或重选时预留的资源。
这里，预留资源可以是针对周期业务预留的。
此外，该实施例中，第一逻辑信道是对于当前数据传输备选的。因此，可选地，所述第一逻辑信道是当前有数据传输需求的所有逻辑信道，或者，当前有数据传输需求的所有逻辑信道中具有最高优先级的逻辑信道。
也就是说，可以将当前有数据传输需求的所有逻辑信道都视为第一逻辑信道；或者将当前有数据传输需求的所有逻辑信息中，仅具有最高优先级的 逻辑信道作为第一逻辑信道。
如此，第一逻辑信道对应的HARQ反馈属性，可包括当前有数据传输需求的所有逻辑信道对应的HARQ反馈属性，也可仅是当前有数据传输需求的所有逻辑信息中具有最高优先级的逻辑信道对应的HARQ反馈属性。
类似的，第一MAC CE是对于当前传输备选的。故，可选地，所述第一媒体接入控制单元MAC CE是当前有传输需求的所有MAC CE，或者，当前有传输需求的所有MAC CE中具有最高优先级的MAC CE。
即，可以将当前有传输需求的所有MAC CE都视为第一MAC CE；或者将当前有数据传输需求的所有MAC CE中，仅具有最高优先级的MAC CE作为第一MAC CE。
如此，第一MAC CE对应的HARQ反馈属性，可包括当前有传输需求的所有MAC CE对应的HARQ反馈属性，也可仅是当前有传输需求的所有MAC CE中具有最高优先级的MAC CE对应的HARQ反馈属性。
另外，应该知道的是，HARQ反馈属性用于指示是否使能反馈。该实施例中，预留资源与确定的HARQ反馈属性未匹配，也可以理解为预留资源无法满足HARQ反馈属性，这样，可选地，所述预留资源与确定的HARQ反馈属性未匹配，包括：
所述HARQ反馈属性为使能反馈，所述预留资源的资源间隔小于HARQ反馈的时长阈值；或者，
所述HARQ反馈属性为使能反馈，所述预留资源的资源间隔小于HARQ反馈的往返时延(Round-Trip Time，RTT)。
即，经确定第一逻辑信道或第一MAC CE对应的HARQ反馈属性为使能反馈(enable)时，进一步通过比较预留资源的资源间隔与该时长阈值或RTT，能够确定两者是否匹配。若HARQ反馈属性为使能反馈，且预留资源的资源间隔小于HARQ反馈的时长阈值，则预留资源与确定的HARQ反馈属性未匹配；反之，则匹配。同样，若HARQ反馈属性为使能反馈，且预留资源的资源间隔小于HARQ反馈的RTT，则预留资源与确定的HARQ反馈属性未匹配；反之，则匹配。
之后，对于当前传输的预留资源与确定的HARQ反馈属性匹配的情况， 进行资源重选。当然，对于当前传输的预留资源与确定的HARQ反馈属性匹配的情况，无需进行资源重选。
可选地，所述时长阈值是通过物理层、MAC层、无线资源控制(Radio Resource Control，RRC)层信令配置或预配置。
另外，可选地，所述方法还包括：
所述当前传输的预留资源与确定的HARQ反馈属性未匹配的情况下，执行以下至少一项：
清除所述当前传输对应的授权；
清除所述预留资源。
这样，对于需要资源重选的场景，还可清除该当前传输对应的授权(grant)，和/或，清除当前预留资源。
如此，针对每个sidelink进程，在以下至少一个条件满足：
条件1：当前资源池被RRC重配/配置；
条件2：当前选择的资源池没有对应的终端自选资源分配模式(mode2)sidelink grant；
条件3：当前mode sidelink grant无法承载无线链路控制层(Radio Link Control，RLC)业务数据单元(Service Data Unit，SDU)(即使采用最大允许的调制与编码策略(Modulation and Coding Scheme，MCS))，并且UE选择对于RLC SDU不进行分包；
条件4：当前mode sidelink grant无法满足当前逻辑信道的延时需求，并且MAC实体决定不采用单MAC PDU的传输方式；
条件5：当前有数据传输需求的第一逻辑信道或第一MAC CE对应的HARQ反馈属性为enable，且当前预留资源的资源间隔小于HARQ反馈的时长阈值或RTT，则执行步骤：
清除当前sidelink进程对应的grant；
触发发送资源重选/选择。
综上，本公开实施例的方法，可以有效的解决预留资源的资源间隔无法满足逻辑信道的HARQ反馈属性的问题。
