### 特征比对表格
| 技术特征描述以及公开性判断结果 | 对比文件原文引用 | 公开性论述 |
| **技术特征A**：一种由用户设备(UE)执行的无线通信的方法。<br>**公开性判断**：《直接公开》 | [0037] “In accordance with an aspect of the present disclosure, there is provided a method for transmitting an uplink signal by a user equipment (UE) in a wireless communication system. The method includes receiving, from a base station, information on a listen-before-talk (LBT) channel sensing type, sensing a channel for an unlicensed band based on the information on the LBT channel sensing type, and transmitting, to the base station, the uplink signal in the unlicensed band after sensing the channel for the unlicensed band.” | 对比文件[0037]段明确公开了一种由UE执行的无线通信方法，其核心步骤包括从基站接收LBT信道感知类型信息、基于该信息感知非许可频段的信道，以及在感知信道后向基站发送上行链路信号。该方法在对比文件的整体技术方案中，是UE在非许可频段进行上行链路接入的基本操作流程，与目标专利中技术特征A所定义的“由UE执行的无线通信方法”这一上位概念的作用相同，均为描述UE侧执行通信方法的起点。因此，该技术特征被对比文件直接公开。 |
| **技术特征B**：在上行链路突发中发送与参考持续时间相关联的上行链路通信。<br>**公开性判断**：《隐含公开》 | [0115] “Further, the terminal can be configured so that uplink signal transmission in N uplink subframes (multi-subframe scheduling) may be performed as one uplink transmission setting information that is transmitted from the base station in a subframe n for the uplink signal transmission of the terminal in a downlink control channel of at least one of a licensed band cell, an unlicensed band cell different from the uplink transmission cell, and the same unlicensed band cell as the uplink transmission cell that includes a subframe n+K.”<br>[0116] “...in the terminal configured so that uplink signal transmission in N uplink subframes (multi-subframe scheduling) may be performed as one uplink transmission setting information...” | 目标专利说明书[0102]段及后续描述了“参考持续时间”是与UE的信道占用时间（COT）内的参考子帧相关联，上行链路突发中在参考持续时间发送的传输为参考上行链路传输。对比文件[0115]-[0116]段描述了终端可以被配置为执行在N个上行链路子帧（多子帧调度）中的上行链路信号传输，这构成了一个上行链路突发（UL burst）。虽然没有明确使用“参考持续时间”这一术语，但本领域技术人员可以合理推断，在多子帧调度的上行链路突发中，必然会存在一个用于定义突发起始、结束或作为调整参考的特定时间点或子帧（例如第一个调度的子帧或最后一个调度的子帧），这个特定时间点或子帧在目标专利中被定义为“参考持续时间”。因此，对比文件隐含公开了在上行链路突发中发送上行链路通信，且该通信与一个作为参考的特定时间（即参考持续时间）相关联。 |
| **技术特征C**：在发送所述上行链路通信之后接收HARQ反馈。<br>**公开性判断**：《直接公开》 | [0135] “Unlike Method 2, the base station transmits a result of uplink signal transmission of the terminal for each terminal, the terminal sets a contention window based on the uplink signal transmission result...”<br>[0075] “When the LAA cell transmits data to the terminal in the channel occupancy period and receives NACK as a reception result for the data transmission from the terminal... When the LAA cell occupying the channel ... receives ACK as a reception result for the data transmission from the terminal...” | 对比文件[0135]段明确提到了基站向终端发送上行链路信号传输的结果（ACK/NACK），终端基于该结果设置竞争窗口。[0075]段也描述了LAA小区（基站）在信道占用期间向终端发送数据后，从终端接收ACK或NACK作为数据传输的接收结果。这直接对应于混合自动重传请求（HARQ）反馈机制。在对比文件的整体方案中，接收HARQ反馈是基站调整自身竞争窗口或终端调整自身竞争窗口的基础，这与目标专利中接收HARQ反馈以用于后续调整LBT竞争窗口的作用相同。因此，该技术特征被直接公开。 |
| **技术特征D**：如果在HARQ反馈窗口的持续时间内未接收到所述HARQ反馈则增加先听后讲(LBT)竞争窗口的大小。<br>**公开性判断**：《隐含公开》 | [0074] “Further, the set contention window may be set using various values including the number of attempts for occupying the channel, occupancy rate for the cannel (e.g., traffic load), and a reception result (e.g., ACK/NACK) of the terminal for the data signal transmitted at the time of occupying the channel.”<br>[0135] “...the terminal sets a contention window based on the uplink signal transmission result...” | 目标专利中“如果在HARQ反馈窗口的持续时间内未接收到所述HARQ反馈则增加LBT竞争窗口的大小”是一种具体的竞争窗口调整规则。对比文件[0074]和[0135]段确立了根据上行链路传输结果（ACK/NACK）来设置（调整）竞争窗口的基本原则。虽然对比文件未明确限定一个“HARQ反馈窗口的持续时间”，但本领域技术人员可以理解，为了判断是否接收到反馈，必然需要在某个预期的时间段内进行监听或判断。未接收到反馈（可视为DTX或NACK的一种表现）作为调整竞争窗口的一种条件，是本领域基于拥塞控制逻辑的合理推断。对比文件已公开了基于NACK增加竞争窗口（[0075]段），将“未收到反馈”作为类似NACK的负面结果来处理，从而触发竞争窗口增加，是隐含公开的内容。 |
| **技术特征E**：所述LBT竞争窗口的大小与上行链路通信的信道接入优先级相关联。<br>**公开性判断**：《隐含公开》 | [0128] “The base station may use a plurality of contention windows depending on a quality of service (QoS) or LBT class, or may apply a contention window set to be different for each QoS or LBT class to all terminals.”<br>[0129] “In a case in which the base station uses a plurality of contention windows depending on LBT class, the base station may select an LBT class corresponding to the uplink transmission period, select a random variable (or backoff counter) within a contention window for the selected LBT class...” | 对比文件[0128]-[0129]段明确公开了可以根据服务质量（QoS）或LBT类别使用不同的竞争窗口集合，并且为上行传输周期选择对应的LBT类别，并在该LBT类别对应的竞争窗口内选择随机变量。这里的“LBT class”与目标专利中的“信道接入优先级”（如CAPC）在概念上对应，都是用于区分不同优先级业务或接入参数的门限类别。因此，竞争窗口的大小与LBT类别（即信道接入优先级）相关联这一技术特征，已由对比文件隐含公开。本领域技术人员可以直接且毫无疑义地确定，不同的LBT类别对应不同的竞争窗口大小范围。 |
| **技术特征F**：以及至少部分地基于所述HARQ反馈是否与所述参考持续时间相关联，来调整所述LBT竞争窗口的大小。<br>**公开性判断**：《隐含公开》 | [0136] “When it is determined that a base station reception result for previous uplink transmission is NACK regardless of hybrid automatic repeat request (HARQ) process for the uplink transmission, the terminal may increase the contention window... The terminal may divide and use the contention window for each HARQ process for the uplink transmission. If the set uplink transmission is set as an HARQ process that is different from an HARQ process for previous uplink transmission, the terminal may select a channel sensing period using a contention window corresponding to the set HARQ process regardless of the base station reception result for the previous uplink transmission.” | 目标专利中“基于HARQ反馈是否与参考持续时间相关联来调整LBT竞争窗口”的核心思想是选择性地依据特定类型的HARQ反馈（与参考持续时间关联的）来调整竞争窗口，而忽略其他类型的反馈。对比文件[0136]段公开了终端可以为每个上行链路HARQ进程划分和使用竞争窗口，并且如果设置的上行链路传输是与先前上行链路传输不同的HARQ进程，则终端可以忽略先前传输的基站接收结果（即HARQ反馈），而使用为新HARQ进程设置的竞争窗口。这揭示了“根据HARQ反馈与特定HARQ进程的关联性来决定是否依据该反馈调整竞争窗口”的基本逻辑。结合前述对“参考持续时间”的隐含公开（其定义了特定类型的传输），本领域技术人员可以合理推理出，可以将“与参考持续时间相关联的上行链路通信”视为一个需要特别关注的特定HARQ进程或传输类型，并仅基于与此类传输相关的HARQ反馈来调整竞争窗口。因此，该技术特征被对比文件隐含公开。 |
| **技术特征G**：确定所述HARQ反馈与跟所述参考持续时间相关联的所述上行链路通信相关联；以及确定所述HARQ反馈包括确认(ACK)。<br>**公开性判断**：《隐含公开》 | [0075] “When the LAA cell occupying the channel using the increased or maintained contention window transmits data to the terminal in the channel occupancy period and receives ACK as a reception result for the data transmission from the terminal, the LAA cell may decrease or maintain the contention window or set the contention window as an initial contention window.”<br>[0135] “When it is set in uplink signal setting information of the terminal transmitted by the base station through a downlink control channel that a base station reception result for previous uplink signal transmission is ACK, the terminal may initialize the contention window.” | 对比文件[0075]和[0135]段多次明确公开了确定接收到的反馈是ACK。同时，如对特征F的论述，对比文件隐含了根据HARQ反馈与特定传输（或HARQ进程）的关联性来处理反馈的逻辑。因此，确定HARQ反馈是ACK，并且该ACK与某个特定的上行链路通信（可隐含对应于“与参考持续时间相关联”的通信）相关联，是本领域技术人员在阅读对比文件后能够合理推断出的操作步骤。确定ACK是直接公开的，确定其与特定传输关联是基于对比文件逻辑的隐含公开。 |
| **技术特征H**：根据权利要求2所述的方法，其中，调整所述LBT竞争窗口的所述大小包括：至少部分地基于确定所述HARQ反馈是ACK并且与跟所述参考持续时间相关联的所述上行链路通信相关联，来重置所述LBT竞争窗口的所述大小。<br>**公开性判断**：《隐含公开》 | [0075] “When the LAA cell occupying the channel using the increased or maintained contention window transmits data to the terminal in the channel occupancy period and receives ACK as a reception result for the data transmission from the terminal, the LAA cell may decrease or maintain the contention window or set the contention window as an initial contention window.”<br>[0135] “When it is set in uplink signal setting information of the terminal transmitted by the base station through a downlink control channel that a base station reception result for previous uplink signal transmission is ACK, the terminal may initialize the contention window.” | 对比文件[0075]和[0135]段明确公开了在接收到ACK反馈时，可以将竞争窗口减少、维持或初始化为初始值。“重置”竞争窗口的大小可以理解为将其设置为一个初始值或默认值。结合对特征F和G的论述，对比文件隐含了根据ACK反馈与特定传输的关联性来决定调整竞争窗口的逻辑。因此，至少部分地基于确定HARQ反馈是ACK并且与特定上行链路通信（隐含为与参考持续时间相关联）相关联，来重置LBT竞争窗口的大小，是本领域技术人员能够从对比文件公开的内容中合理推断出的具体调整方式。 |
| **技术特征I**：确定所述HARQ反馈与跟所述参考持续时间相关联的所述上行链路通信相关联；以及确定所述HARQ反馈包括否定确认(NACK)。<br>**公开性判断**：《隐含公开》 | [0075] “When the LAA cell transmits data to the terminal in the channel occupancy period and receives NACK as a reception result for the data transmission from the terminal, the LAA cell may increase or maintain the contention window.”<br>[0135] “...when it is set in uplink signal setting information of the terminal transmitted by the base station through a downlink control channel that a base station reception result for previous uplink signal transmission is NACK, the terminal may increase the contention window.” | 对比文件[0075]和[0135]段明确公开了确定接收到的反馈是NACK。同时，如对特征F的论述，对比文件隐含了根据HARQ反馈与特定传输（或HARQ进程）的关联性来处理反馈的逻辑。因此，确定HARQ反馈是NACK，并且该NACK与某个特定的上行链路通信（可隐含对应于“与参考持续时间相关联”的通信）相关联，是本领域技术人员在阅读对比文件后能够合理推断出的操作步骤。确定NACK是直接公开的，确定其与特定传输关联是基于对比文件逻辑的隐含公开。 |
| **技术特征J**：根据权利要求4所述的方法，其中，调整所述LBT竞争窗口的所述大小包括：至少部分地基于确定所述HARQ反馈是NACK并且与跟所述参考持续时间相关联的所述上行链路通信相关联，来增加所述LBT竞争窗口的所述大小。<br>**公开性判断**：《隐含公开》 | [0075] “When the LAA cell transmits data to the terminal in the channel occupancy period and receives NACK as a reception result for the data transmission from the terminal, the LAA cell may increase or maintain the contention window.”<br>[0135] “...when it is set in uplink signal setting information of the terminal transmitted by the base station through a downlink control channel that a base station reception result for previous uplink signal transmission is NACK, the terminal may increase the contention window.” | 对比文件[0075]和[0135]段明确公开了在接收到NACK反馈时，可以增加竞争窗口。结合对特征F和I的论述，对比文件隐含了根据NACK反馈与特定传输的关联性来决定调整竞争窗口的逻辑。因此，至少部分地基于确定HARQ反馈是NACK并且与特定上行链路通信（隐含为与参考持续时间相关联）相关联，来增加LBT竞争窗口的大小，是本领域技术人员能够从对比文件公开的内容中合理推断出的具体调整方式。 |
| **技术特征K**：确定所述HARQ反馈不与跟所述参考持续时间相关联的所述上行链路通信相关联；并且其中，调整所述LBT竞争窗口的所述大小包括：至少部分地基于确定所述HARQ反馈不与跟所述参考持续时间相关联的所述上行链路通信相关联来避免调整所述LBT竞争窗口的所述大小。<br>**公开性判断**：《隐含公开》 | [0136] “If the set uplink transmission is set as an HARQ process that is different from an HARQ process for previous uplink transmission, the terminal may select a channel sensing period using a contention window corresponding to the set HARQ process regardless of the base station reception result for the previous uplink transmission.” | 对比文件[0136]段公开了如果设置的上行链路传输是与先前上行链路传输不同的HARQ进程，则终端可以忽略先前传输的基站接收结果（即HARQ反馈）。这实质上就是“避免基于该HARQ反馈调整竞争窗口”的一种表现形式。虽然对比文件是从“不同HARQ进程”的角度描述，而目标专利是从“不与参考持续时间相关联”的角度描述，但二者在技术思想上具有共通性：即并非所有HARQ反馈都用于调整当前关注的竞争窗口。本领域技术人员可以合理推断，当确定接收到的HARQ反馈并非针对所关注的特定传输（如与参考持续时间相关联的传输）时，可以避免基于此反馈调整竞争窗口。因此，该技术特征被对比文件隐含公开。 |
