| 技术特征描述及公开性判断 | 对比文件原文引用 | 公开性论述 |
| **技术特征A**：《隐含公开》<br>通过车辆到万物系统中的第一无线设备识别用于到所述车辆到万物系统中的第二无线设备的传输的数据分组，所述数据分组与第一时延类型相关联 | [0002] "The following relates generally to wireless communication, and more specifically to mechanisms for co-existence between communication modes in a mesh network, such as a mesh wide area network (WAN) that supports the internet of things (IoT)."<br><br>[0043] "In some examples, a wireless device (e.g., a UE) in a location with poor wireless communication coverage may use other wireless devices (e.g., relays) to indirectly communicate with a central node (e.g., a base station) in a mesh WAN. Communications between a relay and an associated UE, or between a first relay and a second relay, may be referred to as D2D communications."<br><br>[0044] "In some examples, a wireless device (e.g., a machine type communication (MTC) device, a low-power device, a device that is used intermittently, a device operating according to a discontinuous reception (DRX) or discontinuous transmission (DTX) configuration) may be operating according to sleep and/or wake-up periods" | 对比文件公开了mesh WAN中的无线设备（如UE、中继）之间的D2D通信，能够识别和传输数据分组。文件[0044]描述了设备可能根据不连续接收（DRX）或非连续传输（DTX）配置按照睡眠和唤醒周期操作，这暗示了与时延相关的概念。本领域技术人员可以推理出在mesh WAN中进行数据传输时，需要考虑时延类型。目标专利中的"车辆到万物系统"与对比文件中的"mesh WAN"在功能和技术架构上具有相似性，两者都涉及无线设备间的直接通信和资源协调。 |
| **技术特征B**：《直接公开》<br>至少部分地基于资源窗口来识别用于所述数据分组的所述传输的候选传输时间间隔集合 | [0045] "In one example of co-existence mechanisms, a wireless device of a mesh WAN (e.g., a UE and/or a relay) using either of the D2D communication modes (e.g., either a scheduled communication scheme or a contention-based communication scheme) may identify wireless communication resources that have been set aside for D2D communications. The wireless communication resources may be partitioned into TTIs (e.g., slots, symbol periods, subframes, frames, etc.) that designate intervals for uplink/downlink communications."<br><br>[0076] "At 420-a, relay 120-e may identify the communication resources that are set aside for D2D communications, and at 420-b, relay 120-f may similarly identify the communication resources that are set aside for D2D communications. As described in the present disclosure, the D2D communication resources may be further partitioned into TTIs, such as slots, for performing uplink and downlink communications." | 对比文件明确公开了无线设备可以识别为D2D通信预留的无线通信资源，这些资源可以被划分为TTI（传输时间间隔），例如时隙、符号周期、子帧、帧等。本领域技术人员可以直接获知如何识别用于传输的候选TTI集合。这与目标专利中"识别用于数据分组的传输的候选传输时间间隔集合"的技术方案实质相同。 |
| **技术特征C**：《隐含公开》<br>其中，所述资源窗口的大小是至少部分地基于所述第一时延类型的 | [0044] "In some examples, a wireless device (e.g., a machine type communication (MTC) device, a low-power device, a device that is used intermittently, a device operating according to a discontinuous reception (DRX) or discontinuous transmission (DTX) configuration) may be operating according to sleep and/or wake-up periods, and interference from other nearby wireless devices may prevent communications with such a device, and/or may lengthen wake durations and/or shorten sleep durations."<br><br>[0059] "During a first discovery interval 205, wireless devices that are configured to act as relays (e.g., relays 120 described with reference to FIG. 1) may advertise relay parameters such as a device identifier, a wake-schedule for the wireless device and associated wireless devices, in addition to energy, latency, and association parameters." | 对比文件[0044]提到了唤醒持续时间可能被延长或睡眠持续时间可能被缩短的情况，[0059]提到了延迟（latency）参数。本领域技术人员可以推理，在mesh WAN中，不同的延迟要求会影响资源分配策略，资源窗口的大小会基于延迟类型进行调整。虽然没有明确使用"资源窗口"术语，但公开了与延迟相关的资源配置概念。 |
| **技术特征D**：《直接公开》<br>至少部分地基于所述资源窗口和用于所述车辆到万物系统中的其它无线设备的预留资源集合使用资源图来从所述候选传输时间间隔集合中选择用于所述数据分组的所述传输的传输时间间隔集合 | [0018] "Some examples of the method, apparatuses, or non-transitory computer-readable medium may include operations, features, means, or instructions for receiving a transmission from another wireless device, and the transmission may include another indication that a different TTI is reserved by the other wireless device, and selecting the TTI based at least in part on the other indication."<br><br>[0045] "The wireless device may select one or more TTIs (TTIs) of the identified communication resources to be reserved for subsequent communications."<br><br>[0076] "At 425-a, the first relay 120-e may select slots for performing subsequent communications, and at 425-b, the second 120-f may also select slots for performing subsequent communications. Selecting slots may include identifying that the slot is not reserved by another wireless device." | 对比文件明确公开了无线设备可以接收来自其他无线设备的传输，该传输包含另一个TTI被预留的指示，以及基于该指示选择TTI。文件还公开了选择未被他无线设备预留的时隙进行通信的方法。这与目标专利中基于其他无线设备的预留资源集合从候选TTI集合中选择传输TTI的技术方案实质相同。 |
| **技术特征E**：《隐含公开》<br>其中所述资源图指示占用资源或未占用资源 | [0016] "In some examples of the method, apparatuses, or non-transitory computer-readable medium, the selecting may include operations, features, means, or instructions for identifying that the TTI is not reserved by another wireless device."<br><br>[0045] "Other wireless devices in the mesh WAN may detect the indication, identify the reserved TTI(s), and refrain from transmitting during the reserved TTI(s)."<br><br>[0076] "Selecting slots may include identifying that the slot is not reserved by another wireless device." | 对比文件虽然没有使用"资源图"这一术语，但明确公开了识别TTI是否被其他无线设备预留（"reserved" vs "not reserved"）的概念。文件[0045]提到其他无线设备可以检测预留指示并识别被预留的TTI，[0076]明确提到识别时隙是否被其他无线设备预留。本领域技术人员可以推理出存在一个记录占用资源和未占用资源的数据结构，其功能与目标专利的"资源图"相同。 |
| **技术特征F**：《隐含公开》<br>其中，选择所述传输时间间隔集合包括：选择在频率上与来自至少一个其它无线设备的重传复用的传输时间间隔中的未占用资源，来自所述至少一个其它无线设备的所述重传与先前解码的数据分组相对应 | [0079] "Alternatively, if the signal strength is substantially low (e.g., below a threshold), relay 120-f may transmit simultaneously with relay 120-e using the reserved slot (e.g., performing D2D communications at 440-b, not shown)."<br><br>[0018] "Some examples of the method, apparatuses, or non-transitory computer-readable medium may include operations, features, means, or instructions for receiving a transmission from another wireless device, and the transmission may include another indication that a different TTI is reserved by the other wireless device, and selecting the TTI based at least in part on the other indication." | 对比文件[0079]公开了如果信号强度低于门限，一个中继可以与另一个中继同时使用预留的时隙进行通信（复用）。文件[0018]公开了接收来自其他无线设备的传输，该传输包含关于不同TTI被预留的指示，并基于该指示选择TTI。本领域技术人员可以推理出可以选择与来自其他无线设备的传输在频率上复用的未占用资源。 |
| **技术特征G**：《隐含公开》<br>使用所述传输时间间隔集合来向所述第二无线设备发送所述数据分组 | [0045] "The wireless device may select one or more TTIs (TTIs) of the identified communication resources to be reserved for subsequent communications. Reserving the TTI(s) may include transmitting, during a second discovery interval, an indication (e.g., a reservation indicator, etc.) that the selected TTI(s) are reserved."<br><br>[0043] "Communications between a relay and an associated UE, or between a first relay and a second relay, may be referred to as D2D communications."<br><br>[0040-a] "relay 120-e may perform D2D communications during a slot reserved by relay 120-e" | 对比文件公开了中继在预留的时隙上执行D2D通信，这涉及向其他无线设备（如关联的UE）发送数据。虽然没有明确说明"使用传输时间间隔集合向第二无线设备发送数据分组"，但文件[0040-a]明确提到在预留的时隙上进行D2D通信，本领域技术人员可以合理推断出在该时隙上进行了数据传输。 |
| **技术特征H**：《隐含公开》<br>还包括：至少部分地基于所述第一时延类型、所述数据分组的初始传输、所述数据分组的重传、所述第一无线设备的能力、所述第二无线设备的软缓冲器、或其任何组合来确定所述资源窗口的所述大小 | [0044] "a device operating according to a discontinuous reception (DRX) or discontinuous transmission (DTX) configuration) may be operating according to sleep and/or wake-up periods"<br><br>[0059] "advertise relay parameters such as a device identifier, a wake-schedule for the wireless device and associated wireless devices, in addition to energy, latency, and association parameters"<br><br>[0011] "the indication may include a TTI index, periodicity information, offset information, or a combination thereof." | 对比文件提到了延迟参数、设备能力（如睡眠/唤醒周期配置）、周期性信息等概念。文件[0059]明确提到广播包括延迟（latency）参数的中继参数，[0011]提到周期性信息。本领域技术人员可以推理，资源窗口的大小可能基于延迟类型、设备能力等因素确定。 |
| **技术特征I**：《隐含公开》<br>还包括：从所述第二无线设备或所述车辆到万物系统中的另一无线设备接收控制信道 | [0059] "During a first discovery interval 205, wireless devices that are configured to act as relays (e.g., relays 120 described with reference to FIG. 1) may advertise relay parameters such as a device identifier, a wake-schedule for the wireless device and associated wireless devices, in addition to energy, latency, and association parameters."<br><br>[0043] "In some examples, a wireless device (e.g., a UE) in a location with poor wireless communication coverage may use other wireless devices (e.g., relays) to indirectly communicate with a central node (e.g., a base station) in a mesh WAN." | 对比文件公开了无线设备可以在第一发现间隔期间广播/接收中继参数，这相当于控制信道功能。文件描述了无线设备之间的通信和信息交换，本领域技术人员可以推理出存在接收控制信道的机制。 |
| **技术特征J**：《直接公开》<br>至少部分地基于所述控制信道来确定用于所述车辆到万物系统中的其它无线设备的所述预留资源集合 | [0018] "Some examples of the method, apparatuses, or non-transitory computer-readable medium may include operations, features, means, or instructions for receiving a transmission from another wireless device, and the transmission may include another indication that a different TTI is reserved by the other wireless device, and selecting the TTI based at least in part on the other indication."<br><br>[0045] "Other wireless devices in the mesh WAN may detect the indication, identify the reserved TTI(s), and refrain from transmitting during the reserved TTI(s)." | 对比文件明确公开了接收来自其他无线设备的传输，该传输包含关于TTI被预留的指示，无线设备基于该指示来识别被预留的资源。这与目标专利中基于控制信道确定其他无线设备的预留资源集合的技术方案实质相同。 |
| **技术特征K**：《直接公开》<br>其中，被选择用于所述数据分组的所述传输的所述传输时间间隔集合排除用于所述车辆到万物系统中的其它无线设备的所述预留资源集合 | [0076] "Selecting slots may include identifying that the slot is not reserved by another wireless device."<br><br>[0045] "Other wireless devices in the mesh WAN may detect the indication, identify the reserved TTI(s), and refrain from transmitting during the reserved TTI(s)." | 对比文件明确公开了选择时隙包括识别该时隙是否被其他无线设备预留，以及其他无线设备应避免在被预留的TTI上传输。这与目标专利中选择的TTI集合排除其他无线设备预留资源的技术方案实质相同。 |
| **技术特征L**：《隐含公开》<br>其中，选择所述传输时间间隔集合包括：从所述候选传输时间间隔集合中选择最早的未占用资源 | [0057] "In this way, the relay 120 may alert nearby devices (e.g., devices within communication range of relay 120) of what TTIs it will use for transmissions, thereby preventing interfering wireless devices from transmitting during the reserved TTI."<br><br>[0076] "Selecting slots may include identifying that the slot is not reserved by another wireless device." | 对比文件公开了选择未预留的时隙进行传输。虽然没有明确提到"最早的"未占用资源，但文件提到了使用发现的第一个可用时隙的概念，本领域技术人员可以推理出可以选择最早的未占用资源。 |
| **技术特征M**：《直接公开》<br>其中，选择所述传输时间间隔集合包括：从所述候选传输时间间隔集合中选择未占用传输时间间隔 | [0076] "Selecting slots may include identifying that the slot is not reserved by another wireless device."<br><br>[0016] "In some examples of the method, apparatuses, or non-transitory computer-readable medium, the selecting may include operations, features, means, or instructions for identifying that the TTI is not reserved by another wireless device." | 对比文件明确公开了选择TTI包括识别该TTI是否被其他无线设备预留，即从未被预留的TTI中进行选择。这与目标专利中选择未占用TTI的技术方案实质相同。 |
| **技术特征N**：《隐含公开》<br>其中，选择所述传输时间间隔集合包括：选择被预留以供其它无线设备使用并且与具有与所述数据分组相比更低的优先级的业务相关联的资源 | [0079] "Alternatively, if the signal strength is substantially low (e.g., below a threshold), relay 120-f may transmit simultaneously with relay 120-e using the reserved slot (e.g., performing D2D communications at 440-b, not shown)."<br><br>[0069] "In some examples the base station may assign a certain communication mode to a first set of D2D communication resources, and assign a different communication mode to a second set of D2D communication resources." | 对比文件公开了如果信号强度低于门限，可以在预留的时隙上进行同时传输。文件还提到了不同通信模式的分配。本领域技术人员可以推理，当信号强度低（表明干扰小或距离远）时，可以使用被其他设备预留的资源，这与抢占低优先级资源的概念相关。 |
| **技术特征O**：《直接公开》<br>还包括：从至少一个其它无线设备接收预留指示，所述预留指示指示被预留用于所述至少一个其它无线设备的资源集合 | [0018] "Some examples of the method, apparatuses, or non-transitory computer-readable medium may include operations, features, means, or instructions for receiving a transmission from another wireless device, and the transmission may include another indication that a different TTI is reserved by the other wireless device"<br><br>[0045] "Reserving the TTI(s) may include transmitting, during a second discovery interval, an indication (e.g., a reservation indicator, etc.) that the selected TTI(s) are reserved. Other wireless devices in the mesh WAN may detect the indication, identify the reserved TTI(s)" | 对比文件明确公开了从其他无线设备接收传输，该传输包含关于TTI被预留的指示（预留指示）。其他无线设备可以检测该指示并识别被预留的TTI。这与目标专利中接收预留指示的技术方案实质相同。 |
| **技术特征P**：《直接公开》<br>确定所述预留指示的信号强度，其中，所述资源是至少部分地基于所述信号强度来从所述资源集合中选择的 | [0019] "Some examples of the method, apparatuses, or non-transitory computer-readable medium may include operations, features, means, or instructions for receiving a transmission from another wireless device, and the transmission may include another indication that the TTI is reserved by the other wireless device. Some examples of the method, apparatuses, or non-transitory computer-readable medium may include operations, features, means, or instructions for measuring a received signal strength of the transmission, and selecting the TTI based at least in part on the measured signal strength of the transmission."<br><br>[0079] "If the signal strength of the received reservation indicator is substantially high (e.g., greater than a threshold value), relay 120-f may refrain from performing D2D communications during that slot (e.g., deferring D2D communications at 440-b). Alternatively, if the signal strength is substantially low (e.g., below a threshold), relay 120-f may transmit simultaneously with relay 120-e using the reserved slot" | 对比文件明确公开了测量传输的接收信号强度，以及基于测量的信号强度选择TTI。如果信号强度高于门限则避免在该时隙传输，如果信号强度低于门限则可以同时使用该预留时隙。这与目标专利中基于信号强度进行资源选择的技术方案实质相同。 |
| **技术特征Q**：《隐含公开》<br>还包括：识别与所述预留资源集合相关联的距离，其中，所述传输时间间隔集合至少部分地基于所述距离和距离门限来排除所述预留资源集合的子集 | [0079] "If the signal strength of the received reservation indicator is substantially high (e.g., greater than a threshold value), relay 120-f may refrain from performing D2D communications during that slot (e.g., deferring D2D communications at 440-b). Alternatively, if the signal strength is substantially low (e.g., below a threshold), relay 120-f may transmit simultaneously with relay 120-e using the reserved slot"<br><br>[0043] "Communications between a relay and an associated UE, or between a first relay and a second relay" | 对比文件通过信号强度来间接判断距离关系（低信号强度通常意味着较大的距离）。当信号强度低于门限时，可以同时使用预留资源，这意味着基于距离因素（通过信号强度体现）来排除或包括某些预留资源。本领域技术人员可以合理推断出基于距离门限进行资源选择的机制。 |
| **技术特征R**：《隐含公开》<br>还包括：确定所述资源窗口的扩展大小 | [0057] "In this way, the relay 120 may alert nearby devices (e.g., devices within communication range of relay 120) of what TTIs it will use for transmissions"<br><br>[0059] "During a first discovery interval 205, wireless devices that are configured to act as relays (e.g., relays 120 described with reference to FIG. 1) may advertise relay parameters such as a device identifier, a wake-schedule for the wireless device and associated wireless devices, in addition to energy, latency, and association parameters." | 对比文件提到了延迟参数和中继参数广播的概念。本领域技术人员可以推理，在不同的延迟要求下，资源窗口的大小可能需要调整或扩展。 |
| **技术特征S**：《隐含公开》<br>至少部分地基于所述资源窗口的所述扩展大小来选择所述传输时间间隔集合 | [0057] "the relay 120 may alert nearby devices of what TTIs it will use for transmissions, thereby preventing interfering wireless devices from transmitting during the reserved TTI"<br><br>[0045] "The wireless device may select one or more TTIs of the identified communication resources to be reserved for subsequent communications." | 对比文件公开了选择预留TTI进行后续通信。本领域技术人员可以推理，基于扩展的资源窗口大小，可以选择更多的TTI进行传输。 |

## 总结
对比文件US20170280472A1主要涉及mesh广域网中不同通信模式之间的共存机制，包括调度式通信方案和基于竞争的通信方案。该文件与目标专利CN113261313B在技术领域上存在一定的相关性（均为无线通信资源管理），但存在以下主要区别：
1. **系统架构不同**：目标专利明确针对V2X（车辆到万物）系统，而对比文件主要针对mesh WAN和IoT设备。虽然两者都涉及无线设备间的直接通信（D2D），但应用场景和技术要求有所不同。
2. **核心概念差异**：目标专利强调基于"时延类型"确定"资源窗口"大小的机制，以及"资源图"的维护和使用，这是目标专利的核心创新点。对比文件虽然公开了TTI选择和预留机制，但没有明确公开资源窗口大小与时延类型的关联，也没有使用"资源图"这一术语。
3. **时延类型处理**：目标专利中数据分组与"第一时延类型"相关联是一个重要特征，而对比文件虽然提到了延迟（latency）参数，但没有明确将数据分组与时延类型关联的概念。
