### 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**:一种用于在无线通信中避免交叉链路干扰的方法 <br> **公开性判断**:隐含公开 | [0044] “The present application describes spectrum access mechanisms in a spectrum shared by multiple adjacent carriers. ... Crosslink interference may occur as a result of the differing transmission directions in adjacent channels for network operating entities.” <br> [0064] “Crosslink interference may occur as a result of the differing transmission directions in adjacent channels for network operating entities. For example, adjacent crosslink interference may be present if a first BS operating on a first channel transmits data, and a second BS operating on a second channel adjacent to the first channel receives data. Similarly, adjacent crosslink interference may be present if a first UE operating on a first channel transmits data, and a second UE operating on a second channel adjacent to the first channel receives data.” | 对比文件[0044]、[0064]段明确指出了在相邻信道上由于传输方向不同(即交叉链路)而产生的干扰(Crosslink interference),并描述了其具体场景。这定义了本申请所要解决的技术问题。虽然对比文件的主要解决方案是“先听后说”(LBT)和基于优先级的频谱共享,但其整体方案的目的正是为了“在多个相邻载波之间实现同步频谱共享”以管理干扰,这实质上是一种“用于在无线通信中避免交叉链路干扰的方法”。因此,本领域技术人员可以从对比文件整体技术方案中合理推断出其公开了一种避免交叉链路干扰的方法。该特征被**隐含公开**。 |
| **技术特征B**:由第一用户装备UE从基站BS接收与第二UE相关联的第二时分双工TDD模式,其中所述第二TDD模式指定与所述第一UE的载波相邻的载波上的第二资源 <br> **公开性判断**:隐含公开 | [0065] “Operators operating on adjacent channels may be aware of the TDD DL/UL configuration of other operators. ... Alternatively, a BS may obtain the TDD pattern using the RTS signal on the adjacent channel, where RTS can indicate the TDD pattern. In an example, the RTS signal indicates the TDD DL/UL configuration of a wireless communication device (e.g., BS or UE).” <br> [0114] “In some embodiments, the method further includes determining, by the first wireless communication device, a first time-division duplex (TDD) DL/UL configuration of the second wireless communication device; and detecting, based on performing the second sensing, an RTS signal from the second wireless communication device, the RTS signal indicating the first TDD DL/UL configuration of the second wireless communication device.” | 对比文件[0065]和[0114]描述了在相邻信道上的操作实体(可对应第二UE)可以知晓其他操作实体的TDD DL/UL配置(即TDD模式)。具体地,可以通过检测相邻信道上的RTS信号来获得该TDD配置,RTS信号指示了第二无线通信设备(可对应第二UE)的TDD DL/UL配置。在目标专利中,“接收与第二UE相关联的第二TDD模式”是为了知晓相邻载波上的资源分配。对比文件中通过感知(检测)RTS信号来获知相邻信道操作实体的TDD配置,其作用与目标专利相同,都是为了使第一设备知晓相邻信道/载波上第二设备的资源分配模式。因此,本领域技术人员可以合理推断出对比文件隐含公开了“由第一UE(或第一无线通信设备)获知(接收/检测)与第二UE(或第二无线通信设备)相关联的第二TDD模式”这一特征。该特征被**隐含公开**。 |
| **技术特征C**:当与所述第二资源中的至少一个第二资源对齐的、来自与所述第一UE相关联的第一TDD模式中指定的第一资源中的至少一个上行链路资源之间存在资源类型不匹配时,由所述第一UE在所述第一UE的所述载波的边缘上建立保护频带,其中所述第一UE的所述载波包括所述至少一个上行链路资源 <br> **公开性判断**:直接公开 | [0070] “Operators A and B share channel C0, and operators C and D share channel C1. A guard band 502 is included at an edge of channels C0 and C1 to mitigate interference from simultaneous transmissions in the adjacent channels.” <br> [0073] “Nodes on one channel may use the reduced bandwidth 506 if they use a different link direction from the detected nodes operating on the adjacent channel. ... For example, additional guard band 504 may be used when the link direction of two operators is not aligned across adjacent channels, when adjacent channel interference is detected.” <br> [0113] “In some embodiments, the method further includes in response to sensing the second wireless communication device during the second sensing time, determining whether a first transmission link direction of the first wireless communication device is the same as a second transmission link direction of the second wireless communication device. ... in response to a determination that the first transmission link direction is not the same as the second transmission link direction, transmitting, by the first wireless communication device, the communication signal with a reduced BW, the reduced BW providing an additional guard band on the first channel...” | 对比文件[0070]、[0073]和[0113]明确公开了以下内容:1. 在相邻信道(C0和C1)的边缘包含保护带(guard band 502)以减轻干扰。2. 当检测到相邻信道干扰,且两个操作实体在相邻信道上的链路方向不一致(即不匹配)时,会使用额外的保护带(additional guard band 504)。3. 具体方法包括:感知第二设备,确定第一和第二设备的传输链路方向是否相同,如果不同(即不匹配),则以减少的带宽(reduced BW)发送通信信号,该减少的带宽在第一信道上提供了额外的保护带。这与目标专利特征C完全对应:“资源类型不匹配”对应于“链路方向不一致”(例如,一个是UL,另一个是DL或特殊资源),“在第一UE的载波的边缘上建立保护频带”对应于“以减少的带宽发送,该减少的带宽提供了额外的保护带”。对比文件公开的内容在整体方案中用于减轻相邻信道间的交叉链路干扰,与目标专利中为解决交叉链路干扰所起的作用相同。因此,该特征被**直接公开**。 |
| **技术特征D**:以及在所述载波上且如在所述第一TDD模式中指定地由所述第一UE向所述BS传送所述第一资源,所述第一资源包括所述至少一个上行链路资源 <br> **公开性判断**:隐含公开 | [0103] “At step 1030, the method 1000 includes communicating, by the first wireless communication device with a third wireless communication device in the first channel, a communication signal in the first channel based on the first sensing and the second sensing. ... The communication signal may be ... a PUCCH signal or PUSCH signal for UL.” <br> [0065] “Additionally, the nodes may coordinate with each other and agree to use a particular pattern for a time period (e.g., 100 ms). The particular pattern may change with each time period. In an example, the semi-static TDD pattern may vary every 100 ms.” | 对比文件[0103]段描述了第一无线通信设备(可视为第一UE)基于感知结果,在第一信道(可视为第一UE的载波)上与第三无线通信设备(可视为BS)通信UL信号(PUCCH/PUSCH)。[0065]段提到了操作实体之间可以协调并使用特定的(TDD)模式。虽然对比文件没有明确描述“按照第一TDD模式中指定的方式”这一具体限定,但其整体方案涉及在共享频谱中按照协调或协商的TDD模式进行通信。本领域技术人员可以理解,在TDD系统中,设备的UL传输必然遵循其自身所配置或协商的TDD模式(即第一TDD模式)中关于UL资源位置的规定。因此,从对比文件公开的“在信道上进行UL通信”以及“使用特定TDD模式”可以合理推断出“按照第一TDD模式中指定地传送包括上行链路资源的第一资源”。该特征被**隐含公开**。 |
| **技术特征E**:所述至少一个上行链路资源在携带所述至少一个上行链路资源的所述载波的所述边缘上具有所述保护频带 <br> **公开性判断**:直接公开 | [0070] “A guard band 502 is included at an edge of channels C0 and C1 to mitigate interference from simultaneous transmissions in the adjacent channels.” <br> [0073] “... additional guard band 504 may be used when the link direction of two operators is not aligned across adjacent channels...” <br> [0113] “... the reduced BW providing an additional guard band on the first channel...” | 对比文件[0070]明确公开了保护带(guard band)位于信道(即载波)的边缘(edge)。[0073]和[0113]进一步说明,当链路方向不匹配时,会使用额外的保护带(additional guard band),这通过减少传输带宽来实现。减少的带宽意味着在信道边缘预留了部分资源不用于传输,从而形成了保护频带。这与目标专利特征E“上行链路资源在载波的边缘上具有保护频带”的描述完全一致。在对比文件中,该保护带的作用同样是减轻相邻信道间的干扰,与目标专利中的作用相同。因此,该特征被**直接公开**。 |
| **技术特征F**:由所述第一UE在来自所述第一TDD模式中指定的所述第一资源的特定资源的一部分上建立第二保护频带;以及其中所述传送进一步包括传送所述特定资源的具有所述第二保护频带的所述部分 <br> **公开性判断**:隐含公开 | [0073] “Nodes on one channel may use the reduced bandwidth 506 if they use a different link direction from the detected nodes operating on the adjacent channel. ... additional guard band 504 may be used when the link direction of two operators is not aligned across adjacent channels...” <br> [0113] “... in response to a determination that the first transmission link direction is not the same as the second transmission link direction, transmitting, by the first wireless communication device, the communication signal with a reduced BW, the reduced BW providing an additional guard band on the first channel...” | 对比文件[0073]和[0113]描述了根据相邻信道链路方向是否匹配,动态决定是否使用“额外的保护带”(additional guard band)。当方向不匹配时,使用减少的带宽进行传输,该减少的带宽在信道边缘形成了额外的保护带。这实质上意味着在“特定资源”(即发生方向不匹配的那个时间/频率资源块)的“一部分”(即靠近相邻信道边缘的那部分带宽)上建立了保护带(即第二保护频带),并且只传送该资源的剩余部分(即具有保护带的部分)。虽然对比文件没有明确区分“第一保护频带”和“第二保护频带”,但其描述的“根据条件动态添加额外保护带”的机制,在逻辑上涵盖了目标专利特征F的内容。本领域技术人员可以合理推断出,在特定条件下(如特定资源发生方向冲突),可以在该资源的一部分上建立保护带。该特征被**隐含公开**。 |
| **技术特征G**:在所述第一UE处监视包括由所述第二UE用来在与传送所述第一资源的载波相邻的载波上传送所述第二资源的所述第二TDD模式的指示符 <br> **公开性判断**:隐含公开 | [0065] “Operators operating on adjacent channels may be aware of the TDD DL/UL configuration of other operators. ... Alternatively, a BS may obtain the TDD pattern using the RTS signal on the adjacent channel, where RTS can indicate the TDD pattern.” <br> [0104] “At step 1020, the method 1000 includes performing, by the first wireless communication device, second sensing in a second sensing time designated for a second channel adjacent to the first channel, the second channel being an operational channel of a second wireless communication device.” <br> [0114] “... detecting, based on performing the second sensing, an RTS signal from the second wireless communication device, the RTS signal indicating the first TDD DL/UL configuration of the second wireless communication device.” | 对比文件[0065]、[0104]和[0114]描述了第一无线通信设备对相邻第二信道进行感知(second sensing),并可以检测来自第二无线通信设备的RTS信号,该RTS信号指示了第二设备的TDD DL/UL配置(即TDD模式)。这种“感知”和“检测RTS信号”的过程,就是“监视”相邻信道上传送的、包含TDD模式信息的“指示符”(即RTS信号)。其目的与目标专利特征G相同,都是为了获取相邻载波上第二设备的TDD模式信息。因此,本领域技术人员可以合理推断出对比文件隐含公开了“在第一UE处监视包括第二TDD模式的指示符”这一特征。该特征被**隐含公开**。 |
| **技术特征H**:其中所述建立进一步包括:在所述第一UE处确定来自所述第一TDD模式中指定的所述第一资源的所述至少一个上行链路资源与来自所述第二TDD模式中指定的所述第二资源的至少一个上行链路资源对齐;以及当在所述第一TDD模式中指定的所述至少一个上行链路资源与在所述第二TDD模式中指定的所述至少一个上行链路资源之间存在对齐时,传送没有所述保护频带的所述至少一个上行链路资源 <br> **公开性判断**:直接公开 | [0076] “In the scheme 600, nodes on one channel use regular bandwidth if they use the same link direction from the detected nodes operating on the adjacent channel. ... If, however, the data transmission of operators A and C are in alignment, additional guard band 504 may be unnecessary.” <br> [0113] “In some embodiments, the method further includes in response to sensing the second wireless communication device during the second sensing time, determining whether a first transmission link direction of the first wireless communication device is the same as a second transmission link direction of the second wireless communication device. In some embodiments, the method further includes in response to a determination that the first transmission link direction is the same as the second transmission link direction, transmitting, by the first wireless communication device, the communication signal with a full BW...” | 对比文件[0076]和[0113]明确公开了以下内容:1. 确定相邻信道上的两个操作实体的数据传输方向是否对齐(in alignment)/相同(the same)。2. 如果数据传输方向对齐(即相同,例如都是UL),则额外的保护带(additional guard band)是不必要的,节点可以使用常规/全部带宽(regular/full BW)进行传输。这直接对应于目标专利特征H:确定上行链路资源是否对齐(方向相同即对齐),并在对齐时,传送没有保护频带的上行链路资源(即使用全部带宽)。对比文件中该判断和操作的作用是优化频谱效率,避免不必要的保护带开销,这与目标专利中根据对齐情况动态调整保护带的作用一致。因此,该特征被**直接公开**。 |
| **技术特征I**:其中所述第一TDD模式包括所述至少一个上行链路资源、至少一个下行链路资源和至少一个特殊资源在一时间段期间在所述第一资源中的位置 <br> **公开性判断**:直接公开 | [0036] “In a time-division duplexing (TDD) mode, UL and DL transmissions occur at different time periods using the same frequency band. For example, a subset of the subframes (e.g., DL subframes) in a radio frame may be used for DL transmissions and another subset of the subframes (e.g., UL subframes) in the radio frame may be used for UL transmissions.” <br> [0065] “Operators operating on adjacent channels may be aware of the TDD DL/UL configuration of other operators. ... Each operator may have a semi-static TDD pattern...” <br> [0114] “... a first time-division duplex (TDD) DL/UL configuration of the second wireless communication device... In an example, each of the first and second wireless communication devices has a semi-static TDD pattern.” | 对比文件[0036]段定义了TDD模式,即UL和DL传输在相同频带的不同时间段发生,并举例说明了帧中的子帧被划分为DL子帧和UL子帧。这隐含了特殊资源(用于切换的保护时间)的存在。[0065]和[0114]段多次提及“TDD DL/UL配置”(TDD DL/UL configuration)和“半静态TDD模式”(semi-static TDD pattern)。本领域技术人员公知,在3GPP标准(如LTE, NR)中,一个完整的TDD配置(或模式)不仅指定了上行链路和下行链路时隙的位置,还指定了特殊时隙(Special slot, 包含下行链路部分、保护周期和上行链路部分)的位置,所有这些都在一个周期(如无线帧)内定义。因此,对比文件公开的“TDD DL/UL配置”或“TDD模式”必然包含上行链路资源、下行链路资源和特殊资源在一段时间内的位置信息。这与目标专利特征I的描述完全一致。该特征被**直接公开**。 |
