**特征比对表格：**
| 技术特征描述及公开性判断 | 对比文件原文引用（段落标号/部分） | 公开性论述 |
| **技术特征A：在侧行链路上接收至少一个侧行链路通信。**<br>**直接公开。** | [0001] “... particularly relates to a technique for user equipment UE that receives a D2D signal ... Note that the D2D communication may also be referred to as side link (sidelink) communication.”<br>[0053] “... so that D2D communication can be performed between the user equipment UE1 and UE2.”<br>[0054] “... user equipment UE at a side of receiving it (the side of transmitting the feedback) is denoted as a receiving UE.” | 对比文件明确其发明涉及用户设备接收D2D（即侧行链路）信号的技术（[0001]），并描述了在支持D2D通信的系统中，用户设备之间进行D2D通信的场景（[0053]），且明确将接收D2D信号的一方定义为接收UE（[0054]）。这直接公开了在侧行链路上接收侧行链路通信的技术特征。 |
| **技术特征B：所述至少一个侧行链路通信包括以下各项中的至少一项：授权、多阶段授权、多分组授权、或中继通信。**<br>**直接公开（授权、多阶段授权、中继通信）；未公开（多分组授权）。** | **授权：**<br>[0006] “For Mode 1, a resource is to be dynamically allocated by a (E)PDCCH to be transmitted from a base station eNB to user equipment UE.”<br>[0073] “... the transmitting UE reports, to the receiving UE, transmission timing (TA) of Data by the SA;”<br>**多阶段授权：**<br>[0141]-[0143] “Contents: ‘existing SCI contents+a retransmission index/identifier, a NDI, the number of times of Data Repetitions, a CSI request, a feedback transmission resource indicator, the number of transmission MAC PDUs, and a TPC command’”<br>[0154] “... the transmitting UE reports, as the retransmission index, an index of the scheduling SCI of Data to be retransmitted...” (隐含多阶段调度)<br>**中继通信：**<br>[0054] “... user equipment UE at a side of transmitting SA/Data (the side of receiving feedback) is denoted as a transmitting UE; and user equipment UE at a side of receiving it (the side of transmitting the feedback) is denoted as a receiving UE.” (设备到设备的直接通信，即中继场景的基础)<br>[0170] “... in Mode 1 resource allocation, D2D transmission resource allocation is performed by signaling from the base station eNB to the UE.” (基站参与的资源分配可视为一种中继控制) | 1. **授权**：对比文件明确描述了在Mode 1模式下，资源由基站通过PDCCH动态分配给UE（[0006]），以及发送UE通过SA（调度分配，一种授权）向接收UE报告数据传输的定时（[0073]）。这直接公开了“授权”这一通信类型。<br>2. **多阶段授权**：对比文件详细描述了支持重传的新SCI格式，其内容包含“重传索引/标识符”和“NDI（新数据指示符）”等（[0141]-[0143]）。重传索引用于指示当前传输是针对哪一次先前的数据传输（[0154]），这实质上公开了一种两阶段（初始传输+基于反馈的重传）的授权或调度机制。虽然未使用“多阶段授权”一词，但技术实质相同：基于前一阶段的传输结果（反馈），决定并触发下一阶段的传输授权。<br>3. **中继通信**：对比文件的核心就是设备到设备（D2D）的直接通信（[0054]），这本身就是中继通信的一种形式（信息在设备间直接中继，无需始终经过基站）。此外，Mode 1资源分配中基站向UE发送资源分配信令（[0170]），也体现了网络节点（基站）对设备间通信的中继控制作用。<br>4. **多分组授权**：对比文件未提及一次授权调度多个独立的数据分组（多分组授权）的概念。其讨论的重传、重复传输或混合调度，都是针对一个传输过程或一个MAC PDU的多次尝试或组合，而非一个授权同时指示多个独立分组的传输资源。 |
| **技术特征C：在所述侧行链路或上行链路上发送包括多个确认的反馈消息。**<br>**直接公开。** | [0013] “... a feedback unit that receives a D2D signal from transmitting user equipment, and that transmits, to the transmitting UE, a feedback signal with respect to the D2D signal by using a predetermined resource;”<br>[0116]-[0117] “Feedback Content Example 1: ACK/NACK”<br>[0127] “... the receiving UE can bundle the ACKs/NACKs for respective MAC PDUs of Data received from the transmitting UE to report it to the transmitting UE.”<br>[0128] “FIG. 12A shows, as a reference, a case where bundling is not performed.” (图示了多个ACK/NACK的反馈)<br>[0205] “... the base station eNB may cause the receiving UE to transmit a feedback signal (e.g., the CSI), and the base station eNB may receive the feedback signal.” (反馈发送给基站，即上行链路) | 对比文件的核心内容之一就是接收UE向发送UE发送针对D2D信号的反馈信号（[0013]），并明确以ACK/NACK作为反馈内容（[0116]-[0117]）。进一步地，文件详细描述了“捆绑（Bundling）”技术，即将多个ACK/NACK合并后报告（[0127]），并以图12A展示了未捆绑时多个ACK/NACK的反馈序列（[0128]）。这直接公开了在侧行链路上发送包含多个确认的反馈消息。同时，文件也提及基站可以触发并接收来自UE的反馈信号（[0205]），这公开了在上行链路上发送反馈消息的可能性。 |
| **技术特征D：所述多个确认中的至少一个是针对在所述侧行链路上接收到的所述授权、所述多阶段授权、所述多分组授权或所述中继通信的。**<br>**隐含公开。** | [0013] “... a feedback unit that receives a D2D signal from transmitting user equipment, and that transmits, to the transmitting UE, a feedback signal **with respect to the D2D signal** by using a predetermined resource;”<br>[0117] “... the receiving UE determines ACK/NACK for **each MAC PDU received from the transmitting UE**; and reports the ACK/NACK to the transmitting UE, as the feedback signal.”<br>[0141] “... the scheduling SCI that supports retransmission etc. **caused by the feedback**...” | 对比文件明确反馈信号是针对接收到的D2D信号（[0013]），且ACK/NACK是针对接收到的每个MAC PDU（[0117]）。而“授权”（如SA）是调度控制信息（SCI），其本身就是在侧行链路上传输的一种D2D信号或控制信息。接收UE在成功解码SA后，才能接收对应的数据（MAC PDU）。因此，当反馈ACK/NACK针对某个MAC PDU时，该确认在逻辑上也是针对调度该MAC PDU的“授权”的。虽然对比文件未明确表述“针对授权的确认”，但根据其整体技术方案，对数据的确认隐含了对调度该数据的授权（SA）的确认，因为授权是数据传输的前提和依据。多阶段授权、中继通信同理，反馈均是针对这些通信过程的结果。因此，该特征被对比文件隐含公开。 |
**结论：**
对比文件US2017347394A1直接公开了目标专利权利要求的技术特征A、B（除“多分组授权”外）、C，并隐含公开了技术特征D。
