下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例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所获得的所有其他实施例，都属于本申请保护的范围。

值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用 于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结果示意图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的上行传输方法200的流程示意图，该方法200可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，在目标业务的业务存活定时器处于运行状态的情况下，和/或，在所述目标业务的业务数据包的时延到达第一门限的情况下，终端设备基于第一重传规则进行HARQ重传。
其中，所述目标业务可以包括但不限于工作于免许可频段的5G空中接口(NewRadio in Unlicensed Spectrum，NRU)技术场景中提供的时延紧急业务，如物联网(I-IOT)业务、虚拟现实(Virtual Reality，VR)视频业务、增强现实(Augmented Reality，AR)视频业务、及虚拟现实和增强现实视频混合视频(Extended Reality，XR)业务、超可靠低延迟通信(Ultra-Reliable andLow-Latency Communication，URLLC)业务等。
所述业务存活定时器(survival timer)是在通信过程中，为确定一种业务是否存续而定义、配置的一个定时器。本实施例中，启动业务存活定时器的方式可以有多种，例如，可在数据最终传输失败时启动业务存活定时器，其中，在该方式中，在一个数据包传输成功时业务存活定时器停止，如果业务存活定时器超时，则确定业务中断。
还例如，在发送数据包成功时启动或者重启业务存活定时器，其中，在该方式中，业务在业务存活定时器运行时存续，在业务存活定时器超时时，确定业务中断。
所述第一重传规则中配置了所述终端设备忽略或放松第一重传定时器(如Configured Grant Retransmission Timer)的运行状态对使用预配置的上行传输许可进行HARQ重传时的限制，所述第一重传定时器的运行状态对HARQ重传时的限制包括：在所述第一重传定时器超时后，使用所述上行传输许可进行HARQ重传。本实施例中，在所述业务存活定时器运行和/或业 务数据包的时延到达第一门限时，通过调整(忽略或放松)第一重传定时器的运行状态对使用预配置的上行传输许可进行HARQ重传时的限制，从而能够较大程度的提高传输资源的利用率，进而增加HARQ重传的机会，尽快正确的传输上行业务数据，降低数据传输延迟，减少业务终止的概率，确保无线通信性能。
示例性的，请结合参阅图3，当一个数据包距离包传输延时预算(Packet Delay Budget，PDB)上限还有一段时间时，为了获得更多的HARQ重传机会，所述终端设备可以忽略预配置的重传定时器(即本实施例中第一重传定时器)对HARQ重传的限制，在预配置的重传定时器还在运行时，直接进行HARQ重传，直到获得HARQ-ACK确认或者到达PDB上限，停止预配置的重传定时器。需要注意，根据第一重传规则的不同，图3中所示的“重传定时器”可以为本申请实施例中所提及的第一重传定时器或第二重传定时器，在此不做具体限制。
此外，在本实施例中，所述目标业务的业务数据包的时延到达第一门限可以理解为：当业务数据包经历的时延已经接近PDB的限制时，可以停止或者放松预配置重传定时器对HARQ重传的限制(即前述的第一重传规则)。在此情况下，所述第一阈值可以根据最大允许的PDB确定，由此减少业务终止的概率。
可选地，所述终端设备启动所述第一重传规则的时间点、所述第一重传规则中涉及的重传参数、以及前述的第一阈值可以由协议约定、高层配置等方式实现，在此不做限制。例如，对于所述第一重传规则，网络侧设备(如基站)可以按业务、逻辑信道或逻辑信道组合、数据无线承载(Data Radio Bearer，DRB)、MAC实体(即cell group)，预配置终端设备停止忽略或放松预配置重传定时器的许可和/或参数，以使得终端设备在接收到许可和/或参数后，可在业务存活定时器运行时，忽略或放松预配置重传定时器对HARQ重传的限制。
本实施例中，在目标业务的业务存活定时器处于运行状态的情况下，和/ 或，在所述目标业务的业务数据包的时延到达第一门限的情况下，终端设备忽略或放松第一重传定时器的运行状态对使用预配置的上行传输许可进行HARQ重传时的限制，由此，能够增加HARQ重传的机会，较大程度的提高传输资源的利用率，降低数据传输延迟，确保无线通信性能。
如图4所示，为本申请一示例性实施例提供的上行传输方法400的流程示意图，该方法400可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法400至少可以包括如下步骤。
S410，在目标业务的业务存活定时器处于运行状态的情况下，和/或，在所述目标业务的业务数据包的时延到达第一门限的情况下，终端设备基于第一重传规则进行HARQ重传。
其中，所述第一重传规则中配置了所述终端设备忽略或放松第一重传定时器的运行状态对使用预配置的上行传输许可进行HARQ重传时的限制，所述第一重传定时器的运行状态对HARQ重传时的限制包括：在所述第一重传定时器超时后，使用所述上行传输许可进行HARQ重传，
需要注意，S410的实现过程除了可以参阅方法实施例200中的相关描述，作为一种可能的实现方式，本实施例中根据第一重传规则的不同，S410的实现过程可以不同，下面结合方式一至方式三对S410中所述的终端设备基于第一重传规则进行HARQ重传的实现过程进行示例性说明，内容如下。
方式一
S410中所述的基于第一重传规则进行HARQ重传的步骤，可以包括：在所述终端设备对第一媒体接入控制(Media Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)已经使用了第一HARQ进程进行初传或重传的情况下，启动第一重传定时器；以及在未接收到HARQ反馈、且所述第一重传定时器未超时的情况下，基于配置的第一上行传输许可(configured grant)对所述第一MAC PDU使用第二HARQ进程进行HARQ重传。
其中，所述第一上行传输许可可以是所述终端设备从预配置的多个上行传输许可中选取的可用的上行传输许可。
需注意，本申请实施例提到的上行传输许可(如第一上行传输许可、第二上行传输许可、第三上行传输许可、第四上行传输许可等)可以是网络侧设备(如基站)按照业务、逻辑信道或逻辑信道组合、DRB、MAC实体等进行配置，且所述第一上行传输许可、第二上行传输许可、第三上行传输许可等可以对应于相同的预配置上行传输许可配置(configured grant configuration)、也可以对应于不同的上行传输许可配置，在此不做具体限制。
另外，所述终端设备在对所述第一MAC PDU进行HARQ重传时，所采用的第二HARQ进程可以与第一HARQ进程相同或不同。
对此，在一种实现方式中，当所述终端设备所采用的第二HARQ进程与第一HARQ进程不同时，也就是，可以临时允许所述终端设备选择与初始选择的第一HARQ进程不同的第二HARQ进程对第一MAC PDU进行HARQ重传，以便所述终端设备可以使用另一个预配置(CG configuration)对应的上行传输许可对第一MAC PDU进行重传，由此可以使得终端设备灵活选择用于该第一MAC PDU传输的时间频率资源(包括相同的载波或不同的载波，相同的20-MHz channel或不同20-MHz channel)进行传输，进而取得分级传输增益。
在本方式一中，所述终端设备通过调整预配置的重传定时器(即前述的第一重传定时器)的使用，使得终端设备可在未接收到HARQ反馈、且所述第一重传定时器未超时的情况下，基于配置的第一上行传输许可对所述第一MAC PDU使用第二HARQ进程进行HARQ重传，由此，增加HARQ重传的机会，降低数据传输延迟，减少业务终止的概率，确保无线通信性能。
此外，在进行HARQ重传时，终端设备还通过采用与HARQ初传时不同的HARQ进程对MAC PDU进行HARQ重传，取得分级传输增益。
方式二
S410中所述的基于第一重传规则进行HARQ重传的步骤，包括：在所述终端设备使用第一HARQ进程完成对第二MAC PDU的初传或重传的情况下，忽略所述第一重传定时器，以及基于预配置的第二上行传输许可，对所 述第二MAC PDU使用第三HARQ进程进行HARQ重传。
其中，方式二中所述的“忽略所述第一重传定时”可以理解为：终端设备在使用第一HARQ进程完成对第二MACPDU的初传和重传后，无论是否启动第一重传定时器，或者第一重传定时器是否超时，均基于预配置的第二上行传输许可，对所述第二MAC PDU使用第三HARQ进程进行HARQ重传，由此，增加HARQ重传的机会，降低数据传输延迟。
另外，与前述第一上行传输许可类似，本方式二中，所述第二上行传输许也可以是所述终端设备从预配置的多个上行传输许可中选取的可用的上行传输许可。
一种实现方式中，所述第三HARQ进程与所述第一HARQ进程相同或不同。对此，可参照前述方式一中对“所述第二HARQ进程与所述第一HARQ进程相同或不同”的相关描述，如本实施例中，在所述第三HARQ进程与所述第一HARQ进程不同时，也可以取得分级传输增益，为避免重复，在此不再赘述。
在本方式二中，终端设备通过调整预配置的重传定时器(即前述的第一重传定时器)的使用，使得终端设备使用第一HARQ进程完成对第二MAC PDU的初传或重传、但所述第一重传定时器未运行的情况下，基于预配置的第二上行传输许可，对所述第二MAC PDU使用第三HARQ进程进行HARQ重传，由此，增加HARQ重传的机会，降低数据传输延迟，减少业务终止的概率，确保无线通信性能。
此外，在进行HARQ重传时，终端设备还通过采用与初传时不同的HARQ进程对MAC PDU进行HARQ重传，如此，可以取得分级传输增益。
方式三
S410中所述的基于第一重传规则进行HARQ重传的步骤，包括：在对第三MAC PDU进行HARQ传输或重传后，启动第二重传定时器；在所述第二重传定时器超时的情况下，基于预配置的第三上行传输许可对所述第三MAC PDU进行HARQ重传。
其中，所述第二重传定时器的定时长度小于所述第一重传定时器的定时长度，也就是说，所述终端设备使用一个比所述业务存活定时器未运行或所述业务数据包的延时未达到第一门限时小的初始值启动重传定时器，并在该重传定时器超时时，基于预配置的第三上行传输许可对所述第三MAC PDU进行HARQ重传，由此通过缩短重传定时器的定时长度的方式，增加HARQ重传的机会，降低数据传输延迟，减少业务终止的概率，确保无线通信性能。
需要注意的是，在本方式三中，第二重传定时器可以是通过对第一重传定时器进行定时长度修改后得到的定时器，也可以是与第一重传定时器独立的定时器，在此不做限制。
进一步，作为一种可能的实现方式，在前述方式一至方式三的基础上，所述终端设备在满足第一条件时，可停止进行HARQ重传的步骤，如停止前述的对所述第一MAC PDU使用第二HARQ进程进行HARQ重传的步骤，或者停止前述的对所述第二MAC PDU使用第三HARQ进程进行HARQ重传的步骤，或者，停止前述的对所述第三MAC PDU进行HARQ重传的步骤。
可选地，所述第一条件包括以下(1)-(5)中的至少一项。
(1)接收到所述第一HARQ进程、第二HARQ进程或第三HARQ进程对应的HARQ ACK信息；可以理解，在所述终端设备接收到HARQ ACK信息时，可判定目标业务的业务数据包传输正确，因此，可以停止HARQ重传。
(2)所述业务数据包的时延达到最大允许的时延预算。
(3)所述HARQ重传的次数达到最大HARQ重传次数。
本实施例中，前述(2)中所述的最大允许的时延预算以及(3)中所述的最大HARQ重传次数均可以通过协议约定、网络配置或高层配置，在此不做限制。
(4)所述业务存活定时器停止或超时。
(5)在启动所述第一重传定时器的情况下，所述第一重传定时器超时。其中，可以理解的是，当所述终端设备对所述第一MAC PDU使用第二HARQ进程进行HARQ重传时，或者对所述第二MAC PDU使用第三HARQ进程 进行HARQ重传时，或者，对所述第三MAC PDU进行HARQ重传时，可以启动第一重传定时器，并在第一重传定时器超时时，停止HARQ重传。
本实施例中，通过停止条件(即第一条件)的设置，能够避免由于无效重传对传输资源的占用，确保无线通信性能。
进一步，作为一种可能的实现方式，在所述业务数据包传输正确或所述业务存活定时器停止运行的情况下，停止所述基于第一重传规则进行HARQ重传的步骤。也就是，如果数据传输正确和/或业务定时器停止运行，那么，所述终端设备可以停止忽略或放松预配置重传定时器对HARQ重传的限制，恢复正常使用预配置重传定时器触发HARQ重传的机制，由此，进一步提高无线通信性能。
另一种可能的实现方式中，所述终端设备在上行传输中，在所述目标业务的业务存活定时器未处于运行状态的情况下，和/或，在所述目标业务的业务数据包的时延未达到所述第一门限的情况下，基于第四上行传输许可进行HARQ初传或重传；在完成所述HARQ初传或重传的情况下，启动或者重启所述第一重传定时器，由此，确保HARQ初传或重传的可靠进行。
需要说明的是，本申请实施例提供的上行传输方法200或400，执行主体可以为上行传输装置，或者，该上行传输装置中的用于执行上行传输方法200或400的控制模块。本申请实施例中以上行传输装置执行上行传输方法200或400为例，说明本申请实施例提供的上行传输装置。
如图5所示，为本申请一示例性实施例提供的上行传输装置500的方框结构示意图，该装置500包括：传输模块510，用于在目标业务的业务存活定时器处于运行状态的情况下，和/或，在所述目标业务的业务数据包的时延到达第一门限的情况下，基于第一重传规则进行HARQ重传；其中，所述第一重传规则中配置了所述终端设备忽略或放松第一重传定时器的运行状态对使用预配置的上行传输许可进行HARQ重传时的限制，所述第一重传定时器的运行状态对HARQ重传时的限制包括：在所述第一重传定时器超时后，使用所述上行传输许可进行HARQ重传。
可选地，所述传输模块510用于在对第一MAC PDU已经使用了第一HARQ进程进行初传或重传的情况下，启动第一重传定时器；以及在未接收到HARQ反馈、且所述第一重传定时器未超时的情况下，基于配置的第一上行传输许可对所述第一MAC PDU使用第二HARQ进程进行HARQ重传。
