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，尤其涉及一种处理方法、通信设备及存储介质。
背景技术
在侧链路传输中，通常在子帧结构的末尾有一个间隙符号，用于Tx/Rx切换(以及当UE RRC接入网络时，通过TA切换到UL传输)。此外，当发送终端将COT(Channel Occupancy Time,信道占据时间)共享给接收终端让它发送PSFCH信道时，也存在一个间隙符号。对于FR1中支持的子载波间隔为15kHz或者30kHz，其符号长度始终大于25μs。
在构思及实现本申请过程中，发明人发现至少存在如下问题：在非授权频谱中如果两次传输之间的间隔大于25μs，则后一次传输不能共享前一次传输所使用的COT，即后一次传输需要使用Type 1 Channel access，由此会降低后一次传输抢占到非授权频谱的概率。
前面的叙述在于提供一般的背景信息，并不一定构成现有技术。

本申请的实施方式
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S0、S1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S1后执行S0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。
终端设备可以以各种形式来实施。例如，本申请中描述的终端设备可以包括诸如手机、平板电脑、笔记本电脑、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、便捷式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等智能终端设备，以及诸如数字TV、台式计算机等固定终端设备。

第一实施例
参照图5，图5为根据第一实施例示出的处理方法的流程示意图，本申请实施例的所述方法可应用于终端设备(如手机，汽车等)，所述处理方法包括以下步骤：
S1：基于预设参数选取或确定循环前缀扩展，基于所述循环前缀扩展生成正交频分复用符号，基于所述正交频分复用符号进行通信。
在本申请实施例中，通过使用循环前缀扩展(Cyclic Prefix Extension，CPE)可以进一步的帮助信道占据时间(Channel Occupancy Time，COT)共享，在该循环前缀扩展中，发射机节点使用它来利用COT，防止它闲置太久而失去对未授权信道的访问。从而保证了两次传输之间的间隔满足法规，使得COT共享能够实现。
可选地，在侧链路传输中，终端发送侧链路信道的时域参考点为来自基站的下行时隙，终端选择终端到基站之间的定时提前量(TA)作为在侧链路上的发送的定时提前量(TA SL)。参照图6及图7，图6为根据第一实施例示出的处理方法的第一原理示意图，图7为根据第一实施例示出的处理方法的第二原理示意图，如图所示，发送终端在发送物理侧链路控制信道(Physical Sidelink Control Channel，PSCCH)和/或物理侧链路数据信道(Physical Sidelink Shared Channel，PSSCH)时使用TA 1作为发送的定时提前量，接收终端在发送物理侧链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)时使用TA 2作为发送的定时提前量。如果发送终端希望将其发起的COT分享给接收终端，则从发送终端的角度看，发送终端发送的控制信道/数据信道与其接收的反馈信道之间的预设间隔应该等于16/25us和/或其他固定值，这些固定值的取值是自然数，这些固定值的单位为微秒。
类似地，如果发送终端将其发起的COT分享给接收终端，接收终端使用该COT发送物理侧链路控制信道和/或物理侧链路数据信道，则从发送终端的角度看，发送终端发送的物理侧链路控制信道和/或物理侧链路数据信道与接收终端发送的物理侧链路控制信道和/或物理侧链路数据信道之间的间隔应该等于16/25us和/或其他固定值，这些固定值的取值是自然数，这些固定值的单位为微秒。
类似地，如果第一发送终端将其发起的COT分享给第二发送终端，第二发送终端使用该COT发送物理侧链路控制信道和/或物理侧链路数据信道、物理侧链路反馈信道、物理侧链路同步信号块(S-SS/PSBCH)、侧链路信道状态信息参考信号(S-CSI-RS)中的至少一项，则从第一发送终端的角度看，第一发送终端发送的物理侧链路控制信道和/或物理侧链路数据信道、物理侧链路反馈信道、物理侧链路同步信号块(S-SS/PSBCH)、侧链路信道状态信息参考信号(S-CSI-RS)中的至少一项与第二发送终端发送的物理侧链路控制信道和/或物理侧链路数据信道、物理侧链路反馈信道、物理侧链路同步信号块(S-SS/PSBCH)、侧链路信道状态信息参考信号(S-CSI-RS)中的至少一项之间的间隔应该等于16/25us和/或其他固定值，这些固定值的取值是自然数，这些固定值的单位为微秒。
为了保障发送终端发送的物理侧链路控制信道和/或物理侧链路数据信道与接收终端发送的物理侧链路反馈信道之间的间隔等于预设间隔，和/或为了保障发送终端发送的物理侧链路控制信道和/或物理侧链路数据信道与接收终端发送的物理侧链路反馈信道之间的间隔等于预设间隔，本申请实施例中以预设间隔为16us或者25us为例，接收终端对发送物理侧链路反馈信道和/或物理侧链路控制信道和/或物理侧链路数据信道的第一个符号和/或所述信道的第一个符号的前一个符号进行循环前缀扩展(CPE)。使用循环前缀扩展，需要确定循环前缀扩展的长度，即基于预设参数选取或确定循环前缀扩展。
可选地，所述预设参数包括以下至少一项：符号数、定时提前量、传播时延、间隔值。
在本申请实施例中，CPE的长度T CPE可以通过如下等式获得：

其中，T 1为发送终端的传输结束时刻，T 2为接收终端的传输的开始时刻，TA 1为发送终端的定时提前量，TA 2为接收终端的定时提前量，T d为信号在Tx-Rx链路上的传播时延。
通过转换，可得
T CPE＝(T 2-T 1)-(TA 2-TA 1)+T d-T gap
＝∑ 0 CiT sym-(TA 2-TA 1)+T d-T gap
＝∑ 0 CiT sym-((TA 2-TA 1)-T d+T gap)
其中，T sym为符号长度，C i为符号数，T gap为间隔值，
TA 1＝(N TA,SL+N TA,offset)·T c；TA 2＝(N TA,SL+N TA,offset)·T c
其中，N TA,SL为侧链路定时提前量参数，由MAC CE(介质访问控制层控制单元)或者RAR(随机接入响应消息)提供；N TA,offset为定时提前量偏置，由高层信令提供或者预定义；时域单位T c＝1/(Δf max·N f)，其中Δf max＝480·10 3Hz，N f＝4096。

可选地，可以通过无线资源控制(Radio Resource Control，RRC)信令去使能传播时延，即循环前缀扩展计算不需要考虑传播时延。

第七实施例
在本申请上述实施例的基础上，本实施例进一步公开了前述实施例中的处理方法。
在本申请实施例中，对于第一发送终端的连续多次传输，考虑到在当前的侧链路传输Sidelink子帧结构中，总是在子帧的末尾有一个间隙符号，用于Tx/Rx切换(以及当UE RRC接入网络时，通过TA切换到UL传输)。需要使用循环前缀扩展技术来保障该间隔的大小等于16/25us或者小于16us。使用循环前缀扩展，需要确定循环前缀扩展的长度。由于连续的两次传输都来自同一个发送终端，因此不需要考虑发送传播时延。
CPE的长度T CPE可以通过如下等式获得：
T 1-TA old+T gap＝T 2-TA new-T CPE
其中，T 1为前一次传输的结束时刻，T 2为后一次传输的开始时刻，TA old为前一次传输的定时提前量，TA new为后一次传输的定时提前量。
通过转换，可得
T CPE＝(T 2-T 1)-(TA new-TA old)-T gap
＝∑ 0 CiT sym-(TA new-TA old)-T gap
＝∑ 0 CiT sym-((TA new-TA old)+T gap)
其中，T sym为符号长度，C i为符号数，T gap为间隔值，TA old＝(N TA,SL+N TA,offset)·T c；TA new＝(N TA,SL+N TA,offset)·T c
对于后一次传输，为了确定CPE的大小，需要选取或确定符号数C i、前一次传输对应的定时提前量TA old、后一次传输对应的定时提前量TA new及间隔值(gap)T gap。
在本申请实施例中，对于符号数C i可通过DCI动态指示，可选地，在DCI格式中增加一个域，所述域用来指示循环前缀需要的符号数。例如增加2比特，所述域指向上述表1。可选地，表格中的C i值分别为C1,C2,C3，C 1＝1 for μ∈{0,1},C 1＝2 for μ＝2；C 2和C 3通过RRC信令配置，其取值为{1,...,28}，可选地，当子载波间隔为15kHz时，C 2和C 3的取值为{1,...,28}；当子载波间隔为30kHz时，C 2的取值为{1,...,28}，C 3的取值为{2,...,28}；当子载波间隔为60kHz时，C 2的取值为{2,...,28}， C 3的取值为{3,...,28}。
可选地，符号数C i与当前侧链路BWP和/或侧链路资源池的子载波间隔关联，例如当子载波间隔为15kHz和30kHz时，C i等于1；当子载波间隔为60kHz时，C i等于2。
可选地，当符号数C i大于1时，发送终端丢弃最后一次传输的后C i-1个符号。
在本申请实施例中，对于前一次传输对应的TA old以及后一次传输对应的TA new，都可通过来自基站的MAC CE获得。
在本申请实施例中，对于前一次传输对应的定时提前量TA old，所述定时提前量TA old为发送终端的前一次传输所使用的定时提前量，所述定时提前量等于TA old＝(N TA,SL+N TA,offset)·T c，其中N TA,SL可以等于当前工作的小区上行的定时提前量N TA_old，N TA＝T A·16·64/2 μ，T A通过RAR消息或者MAC CE获得。N TA,offset通过RRC信令指示获得，或者根据协议预定义获得。
可选地，N TA,SL可以等于零。
可选地，TA old可通过基站发送的MAC-CE通知前一次传输对应的终端。
可选地，TA old可通过基站发送的RAR消息通知前一次传输对应的终端。
在本申请实施例中，对于后一次传输对应的定时提前量TA new，所述定时提前量TA new为发送终端的传输所使用的定时提前量，所述定时提前量等于TA new＝(N TA,SL+N TA,offset)·T c，其中N TA,SL可以等于当前工作的小区上行的定时提前量N TA_new，N TA＝T A·16·64/2 μ，T A通过RAR消息或者MAC CE获得。N TA,offset通过RRC信令指示获得，或者根据协议预定义获得。
可选地，所述定时提前量TA new为后一次传输所使用的定时提前量，所述后一次传输和前一次传输处于同一个COT。
可选地，N TA,SL可以等于零。
可选地，TA new可通过基站发送的MAC-CE通知后一次传输对应的终端。
可选地，TA new可通过基站发送的RAR消息通知后一次传输对应的终端。
在本申请实施例中，对于间隔值，其取值为Xus,16us和/或25us，可以通过DCI动态指示，其中X为小于16的一个取值，X的取值可以通过RRC配置。
可选地，如果DCI指示间隔值为Xus，则发送终端在发送后续的物理侧链路控制信道和/或物理侧链路数据信道、物理侧链路反馈信道、物理侧链路同步信号块(S-SS/PSBCH)、侧链路信道状态信息参考信号(S-CSI-RS)中的至少一项时不需要进行LBT；否则进行一次LBT。
可选地，对于间隔值，其取值为16us和/或25us，可以通过DCI动态指示；
可选地，上述参数，例如符号数，间隔值，还可以通过DCI联合指示，例如配置一个表格，表格中的每一行代表了上述参数的一个取值。表格可以通过RRC信令配置而成。

本申请实施例中，在对于第一终端具有连续多次传输，由于连续的两次传输都来自同一个发送终端，不需要考虑发送传播时延的情况下，通过选取或确定符号数C i、前一次传输对应的定时提前量TA old、后一次传输对应的定时提前量TA new及间隔值，进而确定循环前缀扩展，基于循环前缀扩展生成正交频分复用符号，基于正交频分复用符号进行侧链路信道传输，有助于保留信道占据时间，提高侧链路传输过程中抢占到非授权频谱的概率。拓展了不同应用场景中循环前缀扩展的确定方式，提高了循环前缀扩展的确定方法的灵活性。
