Description

处理方法、通信设备及存储介质 技术领域
本申请涉及通信技术领域，具体涉及一种处理方法、通信设备及存储介质。
背景技术
在NR-U(NewRadio in Unlicensed Spectrum，非授权频谱的新无线电)中，为了避免多个发射机之间的冲突，引入了随机退避机制。随机退避过程首先在竞争窗口(Contention Window,CW)内采用一个随机数初始化退避计数器，该随机数来自均匀分布[0,CW]，以9us的倍数表示传输信道必须保持可用的持续时间。竞争窗口越大，平均退避值就越大，发生冲突的概率就越低。
竞争窗口的大小可以进行调整，这是为了适应与信道的空闲状态，在NR-U中，竞争窗口的大小调整主要是根据对数据信道的HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)反馈动态调整。但是对于没有针对数据信道的HARQ反馈的情形或者只有针对数据信道的HARQ-NACK反馈的情形或者非控制/数据信道的情形，随机退避机制中竞争窗口的大小无法适应调整，容易引起多个发射机之间的通信冲突。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素，此外，本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义，也可能具有不同含义，其具体含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。
应当理解，尽管在本文可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本文范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语"如果"可以被解释成为"在……时"或"当……时"或"响应于确定"。再者，如同在本文中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组， 但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。本申请使用的术语“或”、“和/或”、“包括以下至少一个”等可被解释为包括性的，或意味着任一个或任何组合。例如，“包括以下至少一个：A、B、C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A和B和C”，再如，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A和B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。
应该理解的是，虽然本申请实施例中的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。而且，图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
取决于语境，如在此所使用的词语“如果”、“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
需要说明的是，在本文中，采用了诸如S1、S2等步骤代号，其目的是为了更清楚简要地表述相应内容，不构成顺序上的实质性限制，本领域技术人员在具体实施时，可能会先执行S2后执行S1等，但这些均应在本申请的保护范围之内。
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或者“单元”的后缀仅为了有利于本申请的说明，其本身没有特定的意义。因此，“模块”、“部件”或者“单元”可以混合地使用。

基于上述移动终端硬件结构以及通信网络系统，提出本申请各个实施例。
请参见图3，图3为本申请实施例提供的一种处理方法的流程图。本申请实施例的所述方法可以由通信设备来执行，在本申请处理方法第一实施例中，所述方法可包括如下步骤：
S10，根据第一参考时间内信道状态和/或第二参考时间内接收的反馈信息，确定竞争窗口的大小。
在本申请的一些实施例中，处理方法应用于侧链路竞争窗口的调整，在NR-U/LAA(License Assisted Access,授权频谱辅助接入)中，竞争窗口的大小可以根据对数据信道的HARQ反馈动态调整，对于没有对数据信道的HARQ反馈或者只有对数据信道的HARQ-NACK反馈的场景，当前的基于竞争窗口的随机退避机制则不可用。
在一些实施例中，第一参考时间由最近传输所在的COT(Channel Occupancy Time,信道占据时间)的关联位置确定，例如，第一参考时间由最近传输所在的COT位置确定，或者第一参考时间由最近传输所在的COT内第一次传输的至少一个候选位置确定，或者第一参考时间由最近传输所在的COT关联的竞争窗口对应的N个感知时隙确定，N为正整数，或者第一参考时间由最近竞争窗口大小更新关联的COT位置确定，或者第一参考时间由最近传输包括HARQ使能的COT位置确定。
在一些实施例中，第二参考时间由最近传输所在的COT的关联位置确定，例如，第二参考时间由最近传输所在的COT位置确定，或者第二参考时间由最近竞争窗口大小更新关联的COT位置确定，或者第二参考时间由最近传输包括HARQ使能的COT位置确定。
在一些实施例中，所述最近传输所在的COT为离本次传输最近的一次传输所占据的COT。
在一些实施例中，所述最近竞争窗口大小更新关联的COT为离本次传输最近的一次传输所占据的COT，且其对应的传 输所使用的信道接入过程时，其对应的竞争窗口大小发生了更新。
在一些实施例中，所述最近传输包括HARQ使能的COT为包含HARQ使能的PSSCH信道传输的COT；即在该COT内传输的PSSCH信道存在关联的HARQ反馈；或者在该COT内传输的调度PSSCH信道的PSCCH信道指示HARQ反馈使能。
在一些实施例中，信道状态包括LBT(listen before talk，先听后说)成功、LBT失败、LBT失败所占比例和信道繁忙的感知时隙所占比例中的一项或多项，信道状态主要用于描述当前信道的繁忙程度和占用情况，第一参考时间内的信道状态是确定竞争窗口的大小的重要依据。
在一些实施例中，反馈信息包括NACK反馈的数目、NACK反馈所占比例、ACK反馈的数目以及ACK反馈所占的比例中的一项或多项，反馈信息主要用于描述当前信道的信息传输情况，第二参考时间内接收的反馈信息是确定竞争窗口的大小的重要依据。
在一些实施例中，步骤S10中根据第一参考时间内信道状态，确定竞争窗口的大小的步骤包括：若不存在对数据信道的HARQ反馈，则根据第一参考时间内信道状态，调整竞争窗口的大小或者保持竞争窗口的大小。
在一些实施例中，S10，根据第二参考时间内接收的反馈信息，确定竞争窗口的大小的步骤包括：若仅接收到HARQ-NACK反馈信息，则根据第二参考时间内接收的HARQ-NACK反馈信息，调整竞争窗口的大小。
在本实施例中，当高层信令或者当侧链路控制信息SCI(Sidelink Control Information，侧链路控制信息)将Sidelink HARQ(Sidelink Hybrid Acknowledgment Request,侧链路自动重传请求)反馈去使能(disable)时，接收终端不会对接收到的PSSCH(Physical Sidelink Share Channel,物理侧链路数据信道)进行Sidelink HARQ反馈；或者，当高层信令将Sidelink HARQ反馈为NACK only时，接收终端只会在没有正确解码接收到的PSSCH时反馈Sidelink HARQ-NACK。
当本申请实施例处理方法的执行主体通信设备准备发送PSCCH(Physical Sidelink Control Channel,物理侧链路控制信道)信道和/或PSSCH信道、PSFCH(Physical Sidelink Feadback Channel，物理侧链路反馈信道)信道、S-SS/PSBCH(Sidelink-Synchronization Signal/Physical Sidelink Broadcast Channel，侧链路同步广播信息块)至少之一时，通信设备需要进行Type 1 channel access(类型1信道接入)。首先，通信设备监听信道并等待，直到某频率信道至少在被称为延迟周期的一段时间内可用为止，此延迟周期一般由一个16us加若干个9us时隙组成。延迟周期的长度取决于信道接入优先级的类别，每一个优先级类别对应一个特定的参数，该参数用以确定延迟周期。
具体的，当通信设备进行Type 1channel access(类型1信道接入)时，相关参数如下表1和表2所示：
表1、Channel Access Priority Class(CAPC)
Figure PCTCN2022116564-appb-000001
在表1中，Channel Access Priority Class(p)为：信道接入优先级类别；Channel Access Priority Class(CAPC)for DL为：关于DL(down-link，下行链路)的信道接入优先级类别；m p为：信道接入优先级类别p，延迟周期Td＝16us+m*9us中的m参数值.；CW min,p为：信道接入优先级类别p的最小竞争窗口的大小；CW max,p为：信道接入优先级类别p的最大竞争窗口的大小；T m cot,p为：信道接入优先级类别p，做完一次LBT后能够占用频段的最长时间；allowedCW psizes为：信道接入优先级类别p，允许的竞争窗口的大小。
表2、Channel Access Priority Class(CAPC)
Figure PCTCN2022116564-appb-000002
在表2中，Channel Access Priority Class(p)为：信道接入优先级类别；Channel Access Priority Class(CAPC)for UL为：关于UL(up-link，上行链路)的信道接入优先级类别；m p为：信道接入优先级类别p，延迟周期Td＝16us+m*9us中的m参数值.；CW min,p为：信道接入优先级类别p的最小竞争窗口的大小；CW max,p为：信道接入优先级类别p的最大竞争窗口的大小；T ulmcot,p为：信道接入优先级类别p，做完一次LBT后能够占用频段的最长时间；allowedCW psizes为：信道接入优先级类别p，允许的竞争窗口大小(CWS,Contention Window Size)。
表2最底部英文内容为：备注1：对于p＝3,4，T ulm cot,p＝10ms，如果提供了更高层参数“缺少其他技术-r16”或者“缺少其他技术-r16”，否则，T ulm cot,p＝6ms。
备注2：当T ulm cot,p＝6ms，可通过插入一个或多个感知时隙以增加到8ms。感知时隙的最小持续时间为100us。包括任何此类感知间隙之前的最长持续时间为6ms。
在一些实施例中，通信设备需要进行Type 1 channel access(类型1信道接入)，通信设备监听信道并等待，直到某频率信道至少在被称为延迟周期的一段时间内可用为止，此延迟周期一般由一个16us加若干个9us时隙组成，延迟周期的长度取决于信道接入优先级的类别，参照上述表1和表2。如果在每个9us时隙中至少有4us时间内的接收能量低于阈值，则说明信道可用，即信道空闲。
一旦信道在延迟周期内被确认可用，通信设备启动随机退避机制，参照图4，随机退避过程首先在竞争窗口(Contention Window,CW)内采用一个随机数初始化退避计数器，该随机数N来自均匀分布[0,CW]，以9us的倍数表示传输信道必须保持可用的持续时间。如果信道在每一个9us时隙被检测到空闲(即信道可用)，则退避计数器减1；反之，每当信道被检测到繁忙时，则退避计数器保持不变，直到信道空闲时间达到延迟周期，其中延迟周期的大小为Td＝16+m*9us。一旦退避计数器归零，随机退避过程就完成了，此时通信设备已经获得信道，并且可以使用信道进行传输，直至达到优先级类别所对应的最大信道占用时间。
参照以上表1和表2，随机退避机制定了四种不同的信道接入优先级类别，每个信道接入优先级类别都有单独的竞争窗口，并且竞争窗口的大小的最大值和最小值不同，不同的信道接入优先级类别是按照每个逻辑信道配置的。同样的，对于不同的信道接入优先级类别使用不同的延迟周期。
如果通信设备使用与信道接入优先级类别p相关联的1类信道接入过程进行传输，则在进行退避计数器是否归零判断之前，通信设备将保持竞争窗口的大小，并应用本申请实施例中处理方法以调整这些传输的竞争窗口的大小，在一些可行的实施例中，根据第一参考时间内信道状态和/或第二参考时间内接收的反馈信息，确定竞争窗口的大小。
在本申请实施例中，在没有数据信道的HARQ反馈的情形下或者在只有数据信道的NACK反馈的情形下或者非控制/数据信道的情形下，在随机退避机制启动之后，根据第一参考时间内信道状态和/或第二参考时间内接收的反馈信息，确定竞争窗口的大小，实现依据信道的占用情况和信息传输情况对竞争窗口的大小进行调整，实现随机退避机制中竞争窗口的大小适应调整，避免多个通信设备之间的通信冲突。
参照以上关于随机退避机制的相关解释和说明，在本申请处理方法另一些实施例中，当侧链路控制信息和/或高层信令将Sidelink HARQ反馈去使能(disable)时，接收终端不会对接收到的PSSCH进行Sidelink HARQ反馈，参照图5，处理方法包括：
步骤S1，对于各个信道接入优先级类别p，将竞争窗口大小设置为对应各信道接入优先级类别p适应的最小竞争窗口大小，或者，通信设备保持竞争窗口大小不变。

步骤S2，确定第一参考时间内信道状态，若信道状态满足第一预设条件，则执行步骤S3；若信道状态满足第二预设条件，则执行步骤S1。
在一些实施例中，信道状态包括LBT成功和LBT失败，第一预设条件为LBT失败，第二预设条件为LBT成功，步骤S2包括：

示例性的，如果所述最近的一个COT发生在当前预期COT的Tw之前，则执行步骤Q1；否则执行步骤Q2B1或步骤Q2B2，可选地，所述Tw为正整数，其单位为毫秒或时隙(slot)，例如Tw的取值可以是20、40、60等，Tw可等同于第六门限值。即若第二参考时间与当前预期的COT之间的间隔大于第六门限值，则执行步骤Q1；若第二参考时间与当前预期的COT之间的间隔小于或等于第六门限值，则执行步骤Q2B1或步骤Q2B2。
示例性的，如果所述最近的一个关联竞争窗口大小更新的COT在当前预期COT的Tw之前，则执行步骤Q1；否则执行步骤Q2B1或步骤Q2B2，可选地，所述Tw为正整数，其单位为毫秒或时隙，例如Tw的取值可以是20、40、60等，Tw可等同于第六门限值，关联竞争窗口为上一次成功的COT的竞争窗口。即若最近的一个关联竞争窗口大小更新的COT与当前预期COT的间隔大于第六门限值，则执行步骤Q1；若最近的一个关联竞争窗口大小更新的COT与当前预期COT的间隔小于或等于第六门限值，则执行步骤Q2B1或步骤Q2B2。
可选地，所述第二参考时间由最近传输所在的COT位置确定；
或者，所述第二参考时间由最近竞争窗口大小更新关联的COT位置确定；
或者，所述第二参考时间由最近传输包括HARQ使能的COT位置确定。

示例性的，用以确定第一参考时间的所述COT内传输PSCCH信道、PSSCH信道、PSFCH信道和S-SS/PSBCH至少之一时，其使用信道接入过程(channel access procedure)时，竞争窗口大小发生了更新。
示例性的，用以确定第一参考时间的所述COT内包含HARQ使能的PSSCH信道传输；即在该COT内传输的PSSCH信道存在关联的HARQ反馈；或者在该COT内传输的调度PSSCH信道的PSCCH信道指示HARQ反馈使能。
步骤Q3，增大竞争窗口大小。
可选地，参照上述表1和表2，在步骤Q3中，将竞争窗口大小CWp调整为下一个较大值，直到达到CWmax；即将竞争窗口大小设置为下一个较大的值，例如将竞争窗口大小从3增加到7。所述下一个指的是一组数字中，相邻两个数字中序号较大的那一个数字。当选择的数字为一组数字中序号最大的数字时，不再选择序号更大的数字，一直选择序号最大的数字。
步骤Q4，保持竞争窗口大小不变。
可选地，在步骤Q4中，对于每一个信道接入优先级类别p，保持竞争窗口大小CWp的值；执行步骤Q1或者执行步骤Q2。即保持竞争窗口大小，执行步骤Q1或者步骤Q2。
在一些实施例中，按照以上描述的步骤Q1至步骤Q4确定竞争窗口的大小，并将对应的参数应用于信道接入过程(channel access procedure)。
可选地，上述的步骤Q1、步骤Q2、步骤Q3和步骤Q4可以按顺序排列组合，例如终端在执行完步骤Q1后执行步骤Q2，根据步骤Q2的判断条件，如果满足条件则返回步骤Q1并确定竞争窗口的大小，并将对应的参数应用于信道接入过程(channel access procedure)；如果不满足条件则执行步骤Q3，并执行步骤Q4，在执行完步骤Q4之后确定竞争窗口的大小，并将对应的参数应用于信道接入过程(channel access procedure)。
可选地，上述的步骤Q1、步骤Q2、步骤Q3和步骤Q4中每一步骤都可以单独执行，不依赖于前面的步骤。例如终端在执行完步骤Q1之后确定竞争窗口的大小，并将对应的参数应用于信道接入过程(channel access procedure)。
