## 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 | 公开性论述 |
| **技术特征A**:《隐含公开》<br>确定在经调度SRS传输与经调度下行链路传输之间不需要后保护期 | [0059] "a sub-optimal type-1 GP value/length could be defined for all cases, e.g. 3 symbols to then be fixed."<br>[0060] "A type-2 GP (260) can be utilized also for SRS switching among SW-T-CCs, except a first SW-T-CC, or in-band SRS frequency hopping. The length of type-2 GP (260) can be smaller than that of type-1 GP (250)..." | 对比文件在段落[0059]-[0060]中讨论了保护期长度可以动态调整,type-2 GP的长度可以比type-1 GP更小。这隐含表明在某些情况下可以减少或不需要保护期。结合[0003]中提到的SRS传输与PUSCH/PUCCH的冲突处理,本领域技术人员可以推断出在特定条件下可以省略后保护期。 |
| **技术特征B**:《直接公开》<br>使用第一天线配置来传送经调度SRS传输 | [0028] "The SRS can then be transmitted on the second CC (e.g., SRS CC) in the starting symbol in the D-SRS according to the received SRS transmission configuration or associated parameters."<br>[0043] "SRS transmission initiates within part 2 (240) of the D-SRS subframe for either a wide-band SRs transmission on SW-T-CCs 202 or a sub-band SRS transmission on SW-T-CCs 204, depending on the D-SRS subframe structure..." | 对比文件明确公开了根据SRS传输配置在特定天线配置下传送SRS的技术内容。段落[0043]详细描述了SRS传输在特定的SW-T-CC(第二天线配置)上发起的具体过程,与目标专利中"使用第一天线配置来传送经调度SRS传输"的技术特征完全对应。 |
| **技术特征C**:《直接公开》<br>从第一天线配置改变为第二天线配置 | [0042] "Part 1 (230) and part 3 (270), for example, can be associated with a predefined or pre-configured SRS switching period that can enable the transmission in a D-SRS subframe to be switched from one CC to another CC..."<br>[0045] "In the type-1 GP (250), for example, the RF re-tuning can occur in one CC switching from one CC to other CCs, such as a switching from the SW-F-CC 210 to the SW-T-CC 215." | 对比文件在段落[0042]和[0045]中明确描述了天线切换操作,即从SW-F-CC(第一天线配置)切换到SW-T-CC(第二天线配置)的过程,并详细说明了这种切换所需的保护期和RF调谐过程。这与目标专利中的"从第一天线配置改变为第二天线配置"技术特征完全一致。 |
| **技术特征D**:《直接公开》<br>使用第二天线配置来接收经调度下行链路传输,而无需观察后保护期 | [0073] "UE 2 can receive PDSCH 410 and 445 on two CCs 304, 306 using symbols 0˜5. Symbols 6˜7...and 9 ˜ 10 of this subframe, for example, can be used for CC-based switching..."<br>[0075] "After transmitting the SRS 455 and 460, respectively, the UEs 3 and 4 can switch back to the UL part...from the DL part 475 for further data transmissions..." | 对比文件在段落[0073]和[0075]中描述了UE在完成SRS传输后直接切换回UL部分接收数据的过程,表明了从发射天线配置切换到接收天线配置的实现方式。虽然未明确说明"无需观察后保护期",但结合[0060]中type-2 GP可以小于type-1 GP的描述,以及具体的切换时序图,本领域技术人员可以明确得出该技术方案已被直接公开。 |
| **技术特征E**:《隐含公开》<br>确定不需要后保护期包括:确定在没有后保护期的情况下基站与UE之间的传播延迟足以允许进行天线配置改变 | [0031] "Without expensing extra components, processing or power support for DL can be greater than in DL."<br>[0045] "The type-1 GP (250) can have an enlarged gap to accommodate this first RF re-tuning as well as enable the switching from receiving DL to transmitting UL..." | 对比文件在[0045]中讨论了保护期大小与RF调谐和模式切换时间的关系,隐含表明保护期的必要性取决于切换所需时间。虽然未直接提及"传播延迟",但本领域技术人员可以结合通信系统的基本原理( propagation delay影响切换时间)推断出该技术特征。 |
| **技术特征F**:《隐含公开》<br>确定不必接收经调度下行链路传输的第一码元 | [0051] "a UE can determine at least one of a number HARQ processes, a HARQ timing for the PDSCHs, transmission of periodic CSI feedback and SRS based on the DL HARQ reference configuration."<br>[0065] "Thus, a collision of the UL control with the SRS can be more likely to be avoided..." | 对比文件在[0051]中描述了UE可以根据HARQ参考配置确定调度时机,隐含表明UE可以判断是否需要接收某些下行链路传输。结合[0065]中避免碰撞的描述,本领域技术人员可以推断出UE可以确定不需要接收下行链路的第一码元。 |
| **技术特征G**:《隐含公开》<br>确定不需要后保护期包括:从基站接收指示不需要后保护期的DCI | [0093] "In another aspect, a dynamic aperiodic SRS (A-SRS) transmission timeline can be provided. For example, A-SRS transmission timeline can be explicitly signaled to a UE using a new information element (IE) in DCI format (e.g., DL grant)." | 对比文件在[0093]中明确公开了通过DCI格式动态向UE指示SRS传输时间线的技术方案。虽然未直接提及"不需要后保护期"的指示,但结合动态信令的上下文,本领域技术人员可以合理推断出DCI可以用于指示保护期相关的调度信息。 |
| **技术特征H**:《直接公开》<br>进一步包括:从网络接收网络资源分配,其中:网络资源分配包括SRS资源集,SRS资源集中的第一SRS资源通过中间保护期与第二SRS资源分开,并且第一SRS资源之前是前保护期 | [0026] "The SRS transmission configuration can comprise a set of parameter for generating the SRS transmission. For example, these parameters can comprise at least one of: a first CC and a second CC, one or more dedicated-SRS (D-SRS) subframes..."<br>[0042] "As shown in the D-SRS subframe structure 205, each D-SRS subframe can be partitioned into three parts 230, 240 and 270..."<br>[0045] "In the type-1 GP (250), for example, the RF re-tuning can occur in one CC switching from one CC to other CCs..." | 对比文件在[0026]中描述了包含D-SRS子帧的SRS传输配置参数集,在[0042]中详细描述了D-SRS子帧被划分为三部分的结构,以及[0045]中描述的保护期用于CC切换。这完整公开了目标专利中关于SRS资源集、网络资源分配、中间保护期和前保护期的技术特征。 |
| **技术特征I**:《隐含公开》<br>前保护期包括零功率SRS资源 | [0028] "In addition, the second CC can be configured to only enable SRS transmission in the UL, and thus, not enable PUSCH/PUCCH transmissions for a TDD serving cell..."<br>[0040] "Additionally or alternatively, the CCs can only be utilized for SRS only without any other physical channel or reference signal sharing the SRS CC..." | 对比文件在[0028]和[0040]中描述了SRS CC被配置为仅用于SRS传输,不能用于其他物理信道传输。虽然未明确提及"零功率SRS资源",但本领域技术人员可以理解这些仅配置SRS的载波在保护期期间相当于零功率传输。 |
| **技术特征J**:《直接公开》<br>无线通信网络是3GPP新无线电NR网络 | [0003] "Wireless mobile communication technology uses various standards and protocols to transmit data between a node (e.g., a transmission station) and a wireless device (e.g., a mobile device)..."<br>[0004] "In 3GPP radio access network (RAN) LTE systems..." | 对比文件在[0003]和[0004]中明确提及了3GPP无线接入网络和LTE系统,并且在整个文档中讨论了载波聚合、特殊子帧等NR系统的关键技术特征。虽然部分内容涉及LTE,但文档整体涵盖了3GPP新无线电网络的相关技术。 |
