### 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《直接公开》** | [0021] “In some implementations, the LTE device 102 comprises an LTE coexistence unit 104, ... The LTE device 102 and the WLAN device 110 communicate via an interface 120. In one implementation, the interface 120 can be a physical interface comprising wires connecting the LTE device 102 and the WLAN device 110.” <br> [0022] “At stage A, the LTE coexistence unit 104 transmits the LTE schedule information 108 to the WLAN coexistence unit 112. The LTE schedule information 108 can indicate timing information of coexistence events such as a start time of LTE packet transmission, a start time of LTE packet reception, a transmission/reception duration, packet priority, etc.” | 对比文件公开了LTE设备（第一RAT）通过物理接口（第一物理连接）向WLAN设备（第二RAT）传送LTE调度信息（第一操作信息）。该LTE调度信息包含了传输/接收开始时间、持续时间等操作参数。其作用是为了协调WLAN和LTE设备的通信时间以避免干扰，这与目标专利中通过交换操作信息来管理共存问题的目的相同。本领域技术人员能够毫无疑义地确定该内容公开了技术特征A。 |
| **技术特征B《直接公开》** | [0023] “At stage B, the WLAN coexistence unit 112 determines a time interval during which only the WLAN device 110 can communicate (“WLAN allocated communication time interval”) and a time interval during which only the LTE device 102 can communicate (“LTE allocated communication time interval”). ... The WLAN coexistence unit 112 can also notify the LTE coexistence unit 104 of the WLAN allocated communication time interval and the LTE allocated communication time interval.” <br> [0029] “At block 206, a notification of the WLAN allocated communication time interval and the LTE allocated communication time interval is provided to the collocated LTE device.” | 对比文件公开了WLAN设备（第二RAT）通过相同的物理接口（第二物理连接）向LTE设备（第一RAT）传送WLAN分配的通信时间间隔和LTE分配的通信时间间隔（第二操作信息）。该信息用于告知LTE设备其被分配的通信时段。其作用同样是协调双方通信以避免冲突，与目标专利中的作用相同。本领域技术人员能够毫无疑义地确定该内容公开了技术特征B。 |
| **技术特征C《隐含公开》** | [0044] “In some implementations, when the LTE device 102 operates in a frequency division duplex (FDD) mode ... the LTE device 102 may continue to receive LTE packets from the LTE base station during the WLAN allocated communication time interval and may only prevent LTE packet transmissions during the WLAN allocated communication time interval. When the LTE device 102 operates in a time division duplex (TDD) mode, the LTE device 102 may prevent LTE packet transmissions and LTE packet receptions during the WLAN allocated communication time interval.” | 对比文件明确指出了LTE设备在FDD和TDD模式下，其在WLAN分配时段内的行为（例如是否允许接收）是不同的。这意味着设备需要知道当前的无线配置（FDD/TDD）以决定如何操作。虽然对比文件未明文记载“改变第一物理连接的协议”，但为了实现所描述的、依赖于无线配置的不同行为协调，本领域技术人员可以合理推断，需要通过接口传递的信息内容或解释该信息的规则（即协议）需要根据当前的无线配置（FDD或TDD）进行相应改变。例如，在TDD模式下，接口信号可能指示“禁止所有LTE活动”；而在FDD模式下，同一信号可能仅指示“禁止LTE发送”。因此，技术特征C被隐含公开。 |
| **技术特征D《隐含公开》** | [0022] “The LTE schedule information 108 can indicate timing information of coexistence events such as a start time of LTE packet transmission, a start time of LTE packet reception, a transmission/reception duration, packet priority, etc.” <br> [0044] (同上) | 技术特征D是技术特征C改变协议后的具体结果，即协议改变后，第一物理连接被配置为携带第三操作信息。对比文件已公开了第一物理连接携带LTE调度信息（第一操作信息）。当如技术特征C所推断的，协议根据无线状况（FDD/TDD）改变时，该连接所携带的信息内容也可能随之改变。例如，在TDD模式下可能携带“TX/RX活动”指示，而在FDD模式下可能仅携带“TX活动”指示。这种为适应不同配置而改变所携带信息内容的情形，正是“配置为携带...第三操作信息”的体现。因此，结合对技术特征C的推理，技术特征D也被隐含公开。 |
| **技术特征E《直接公开》** | [0044] “In some implementations, when the LTE device 102 operates in a frequency division duplex (FDD) mode (e.g., using LTE Band 7 that is very close to the 2.4 GHz ISM band) ... However, when the LTE device 102 operates in a time division duplex (TDD) mode, ... ” | 对比文件直接、明确地公开了LTE设备可以在FDD无线配置（例如使用频带7）或TDD无线配置下操作。这两种配置是截然不同的无线状况。同时，使用不同频带（例如频带7或频带40）也意味着所使用的载波频率发生了变化。因此，技术特征E所定义的“无线状况的变化是在频分双工(FDD)无线配置与时分双工(TDD)无线配置之间的切换或所使用的载波频率的变化”已被对比文件直接公开。 |
| **技术特征F《直接公开》** | [0022] “At stage A, the LTE coexistence unit 104 transmits the LTE schedule information 108 to the WLAN coexistence unit 112. The LTE schedule information 108 can indicate timing information of coexistence events such as a start time of LTE packet transmission, a start time of LTE packet reception...” <br> [0023] “... The WLAN coexistence unit 112 can also notify the LTE coexistence unit 104 of the WLAN allocated communication time interval and the LTE allocated communication time interval.” | 对比文件中，LTE设备和WLAN设备通过物理接口相互交换LTE调度信息和通信时间间隔分配信息。这些信息直接指明了各设备计划进行通信（发送或接收）的时间。交换这些信息的根本目的，就是为了让双方知晓对方何时可能进行通信，从而判断是否存在潜在干扰并据此调整自身行为。因此，所交换的信息本身就是“对潜在地干扰性通信的指示”。这与目标专利中技术特征F的作用完全相同。本领域技术人员能够毫无疑义地确定该内容公开了技术特征F。 |
| **技术特征G《直接公开》** | [0025] “At stage D, the WLAN coexistence unit 112 coordinates WLAN transmission and WLAN reception to minimize overlapping with LTE transmission and LTE reception based, at least in part, on the WLAN allocated communication time interval and the LTE allocated communication time interval.” <br> [0030] “At block 210, WLAN packets are exchanged with one or more WLAN stations connected to the WLAN device. ... During the WLAN allocated communication time interval, ...” <br> [0042] “At block 306, LTE packets are exchanged with an LTE base station to which the LTE device is connected. ... During the LTE allocated communication time interval, ...” | 对比文件明确记载了WLAN设备和LTE设备基于通过接口交换的调度信息（即技术特征F中的“指示”）来协调和调整各自的通信。例如，WLAN设备只在WLAN分配的时间间隔内进行通信，LTE设备只在LTE分配的时间间隔内进行通信（或根据FDD/TDD模式调整接收行为）。这种根据交换信息来限制或安排通信时间的行为，就是“调整通信”的具体体现。其目的正是为了减轻潜在干扰。本领域技术人员能够毫无疑义地确定该内容公开了技术特征G。 |
| **技术特征H《直接公开》** | [0001] “... to a coexistence mechanism for collocated WLAN and WWAN communication devices.” <br> [0020] “... the LTE device 102 (e.g., which may be referred to as “LTE user equipment (UE)”) ...” | 对比文件的标题和全文内容均围绕WLAN和WWAN（无线广域网）设备的共存机制展开。其中明确将LTE设备作为WWAN设备的例子。LTE是典型的无线广域网（WWAN）技术。因此，对比文件公开了第一无线接入技术是无线广域网（WWAN）。 |
| **技术特征I《直接公开》** | [0001] “... to a coexistence mechanism for collocated WLAN and WWAN communication devices.” <br> [0020] “... and the WLAN device 110 ...” | 对比文件的标题和全文内容明确将WLAN（无线局域网）作为与WWAN共存的另一方。因此，对比文件直接公开了第二无线接入技术是无线局域网（WLAN）。 |
| **技术特征J《隐含公开》** | [0025] “At stage C, ... the LTE processing unit 106 may transmit the LTE packets only during the LTE allocated communication time interval but may receive LTE packets ... from the LTE base station during either the LTE or the WLAN communication intervals.” <br> [0044] “In some implementations, when the LTE device 102 operates in a frequency division duplex (FDD) mode ..., the LTE device 102 may continue to receive LTE packets from the LTE base station during the WLAN allocated communication time interval...” <br> [0068] “... the WLAN processing unit 114 may be permitted to receive WLAN packets during the LTE receive intervals 804E-804H of the LTE allocated communication time interval 822.” | 对比文件描述了多种时间协调方案。其中一种方案（如图6-8所述）允许WLAN设备在LTE分配的时间间隔内的LTE接收间隔期间接收WLAN分组。这意味着WLAN通信被安排在了LTE通信的间隙（即LTE的接收时段）进行。另一种方案（如FDD模式下）允许LTE在WLAN分配时段内接收数据，这也是一种在对方通信间隙进行的操作。因此，对比文件隐含公开了“在第一无线接入技术的通信间隙期间与第二无线接入技术通信”这一调整通信的方式。 |
| **技术特征K《隐含公开》** | [1006] “... the WLAN processing unit 114 can identify one or more WLAN access points with which the WLAN device 110 can establish the WLAN communication link.” <br> [1010] “... the WLAN coexistence unit 112 can select the target WLAN access point as one of the WLAN access points identified at block that is associated with a WLAN operating frequency that is sufficiently separated from the LTE operating frequency.” | 对比文件图10的流程描述了当WLAN设备配置为客户端站点时，为了最大化与共存LTE设备的频率分离，会识别可用的WLAN接入点，并选择其工作频率与LTE工作频带分离最远的一个作为目标接入点与之建立连接。这实质上就是“通过不同的接入点与所述第二无线接入技术通信”的一种具体实现方式，即从多个可选接入点中选择一个干扰更小的进行通信。因此，该技术特征被对比文件隐含公开。 |
| **技术特征L《隐含公开》** | 未找到直接对应描述。 | 目标专利说明书中提到，如果WLAN通信可能干扰使用UMTS网络的语音电话，共存管理器可以将数据路由通过WWAN（UMTS数据网络）而不是WLAN。对比文件全文集中于通过时间调度和频率选择来解决WLAN和WWAN（LTE）的共存问题，并未提及或暗示当两者共存时，会将数据通信从WLAN切换到WWAN。这种切换涉及到网络选择和路由决策，超出了对比文件所解决的物理层/链路层时间/频率协调范畴。因此，对比文件没有公开或隐含公开此技术特征。 |
| **技术特征M《隐含公开》** | [0031] “At block 216, the WLAN device switches to a low power state. ... The WLAN device 110 does not transmit WLAN packets or receive WLAN packets when the WLAN allocated communication time interval is not in progress (i.e., during the LTE allocated communication time interval).” <br> [0042] “At block 312, the LTE device switches to a low power state. ... The LTE device 102 may not transmit LTE packets or receive LTE packets when the LTE allocated communication time interval is not in progress (i.e., during the WLAN allocated communication time interval).” | 对比文件描述了在时间分割调度机制中，当设备处于非分配时段时，会切换到低功耗状态，不进行任何通信活动。当第一无线接入技术（WWAN/LTE）处于空闲模式（即非活动通信时段）时，其自身不进行通信。而第二无线接入技术（WLAN）在该时段内被禁止通信（切换到低功耗状态），这客观上“保护”了第一无线接入技术可能进行的任何低优先级后台活动（如寻呼、测量），使其免受WLAN的潜在干扰。因此，可以合理推断出“当所述第一无线接入技术处于空闲模式时，保护所述第一无线接入技术的通信”这一技术方案。 |
