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:生成包括资源分配协调信息的消息**《隐含公开》[0132]段:"MAC Control element (CE) (including but not limited to a V2X MAC CE) may be used for the indication. The MAC control CE may include one or more of the following: a command type...priority information...frequency resource location information...time resource location information...resource reservation interval/period..."<br><br>[0149]段:"a sidelink V2X MAC CONTROL CE. In some embodiments, a broadcast mode may be used...The MAC control CE may include one or more of the following: a command type..."对比文件公开了MAC CE可用于传输资源协调相关的信息(包括优先级信息、资源位置信息等),这些信息可被用于资源协调。但对比文件的重点是mute命令,而非明确针对"资源分配协调信息"的概念。因此为隐含公开。
**技术特征B:消息被配置为向第二无线设备指示未被占用以用于第二无线设备向无线设备发送侧行链路通信的侧行链路通信资源**《直接公开》[0127]段:"frequency resource location information, including but not limited to a set of frequency sub-channels, sub-bands or physical resource blocks...time resource location information, including but not limited to a set of subframes or slots periodically occurring in time...the indicated resources are to be excluded from candidates resources for selection"对比文件明确公开了DCI格式中包含资源位置信息,通过排除某些资源(即已占用资源),隐含地指示了可用的侧行链路通信资源。这与目标专利中指示"未被占用的资源"的技术特征实质相同。
**技术特征C:还包括用于由第二无线设备至无线设备的传输的优选资源列表**《隐含公开》[0127]段:"priority information, for instance that transmissions with lower priority are to be muted on indicated resources and the indicated resources are to be excluded those from candidates resources for selection"对比文件通过优先级信息来指示资源,排除低优先级资源意味着高优先级资源可被使用,隐含公开了优选资源的概念。
**技术特征D:或避免用于由第二无线设备至无线设备的传输的资源列表**《直接公开》[0127]段:"frequency resource location information...the indicated resources are to be excluded from candidates resources for selection"<br><br>[0143]段:"transmissions with lower priority are to mute transmission on indicated resources and are to exclude those resources from candidate resources for selection"对比文件明确公开了要排除/避免的资源列表,这与目标专利中"避免用于传输的资源列表"实质相同。
**技术特征E:向第二无线设备发送包括资源分配协调信息的所述消息**《直接公开》[0141]段:"the cellular MAC layer may send and/or request physical layer to send a message/element to indicate a mute operation for radio resource(s). The UE 102 may then or in parallel transmit the message/element."<br><br>[0125]段:"the gNB 105 may transmit a PDCCH that indicates a mute operation"对比文件明确公开了向其他UE发送包含mute指示的消息。
**技术特征F:生成包括资源分配协调信息的消息包括:生成包括资源分配协调信息的MAC控制元素(CE)**《直接公开》[0132]段:"including but not limited to embodiments in which the PDSCH is used for a mute indication, MAC Control element (CE) (including but not limited to a V2X MAC CE) may be used for the indication"<br><br>[0150]段:"for mode-3...a mode-3 UE 102 may request gNB 105 to indicate resource reservation/mute through Uu air-interface using the MAC CE MUTE COMMAND. In some embodiments, for mode-4...a mode-4 UE 102 may signal resource reservation and mute in PSSCH using MAC CE MUTE COMMAND"对比文件明确公开了使用MAC CE传输资源协调信息(包括mute命令)。
**技术特征G:生成包括资源分配协调信息的消息包括:将SCI消息配置为包括资源分配协调信息**《直接公开》[0142]段:"an existing/legacy sidelink control information (SCI) or other SCI format may be used for one or more of the following: to indicate a mute operation, to indicate information related to the mute operation..."<br><br>[0143]段:"the SCI signaling in the PSCCH may include priority information..."对比文件明确公开了使用SCI消息传输mute指示和相关信息。
**技术特征H:还包括:从第三无线设备接收与由第三无线设备作出的侧行链路通信资源保留有关的信息**《直接公开》[0147]段:"for mode-3...a mode-3 UE 102 that detects sidelink request for mute/reservation of resource on sidelink may report information about such resources to eNB 104/gNB 105 to prevent scheduling on such resources"<br><br>[0148]段:"for mode-4...a mode-4 UE 102 that detects sidelink request for mute/reservation of resource on sidelink may relay this information..."对比文件明确公开了UE可以接收(检测)来自其他UE的侧行链路资源保留请求信息。
**技术特征I:基于从第三无线设备接收的信息来确定资源分配协调信息**《隐含公开》[0147]段:"a mode-3 UE 102 that detects sidelink request for mute/reservation of resource on sidelink may report information about such resources to eNB 104/gNB 105 to prevent scheduling on such resources"对比文件隐含公开了基于检测到的资源保留信息来采取措施(向网络报告),这可以合理推断出基于接收的信息来确定资源协调信息。
**技术特征J:生成包括资源分配协调信息的所述消息包括:将消息配置为包括可用资源和已占用资源的映射**《隐含公开》[0127]段:"frequency resource location information...a set of frequency sub-channels, sub-bands or physical resource blocks...time resource location information...a set of subframes or slots periodically occurring in time"对比文件中的资源位置信息集合可以被理解为资源映射的一种形式,隐含公开了可用/已占用资源的映射概念。
