## 技术特征比对表格
| 技术特征 | 公开性判断 | 对比文件原文引用 | 公开性论述 |
| 技术特征A：一个或多个存储器 | **《隐含公开》** | 【0059】Controllers/processors 330, 360 and 390 may control the operation at wireless device 110, relay station 120, and base station 130, respectively. Memories 332, 362 and 392 may store data and program codes for wireless device 110, relay station 120, and base station 130, respectively. | 对比文件公开了无线设备110、中继站120和基站130分别具有存储器332、362和392，用于存储数据和程序代码。虽然对比文件没有明确使用“一个或多个存储器”的表述，但本领域技术人员可以理解，每个通信设备都需要存储器来存储数据和程序代码，因此隐含公开了存储器这一技术特征。 |
| 技术特征B：耦合至所述一个或多个存储器的一个或多个处理器 | **《隐含公开》** | 【0059】Controllers/processors 330, 360 and 390 may control the operation at wireless device 110, relay station 120, and base station 130, respectively. Memories 332, 362 and 392 may store data and program codes for wireless device 110, relay station 120, and base station 130, respectively. | 对比文件公开了控制器/处理器330、360和390分别控制无线设备110、中继站120和基站130的操作，并且存储器332、362和392存储数据和程序代码。本领域技术人员可以理解，处理器与存储器之间存在耦合关系以实现数据存取和程序执行，因此隐含公开了处理器耦合至存储器的技术特征。 |
| 技术特征C：所述一个或多个存储器和所述一个或多个处理器被配置成：传送包括饱和信号的经压缩传输 | **《隐含公开》** | 【0028】OFDM and SC-FDM have certain desirable characteristics such as the ability to combat multipath effects. However, a major drawback with OFDM, and to a lesser extend with SC-FDM, is a high PAPR of an output signal...<br>【0032】System 100 may support data transmission with feedback of ACK and NACK in order to address high PAPR and improve performance. A transmitter may send a transmission of a data packet with channel encoding and either with or without PAPR encoding. | 对比文件公开了系统支持PAPR（峰均功率比）相关的传输，并提到了PAPR编码和信道编码。PAPR高会导致输出信号产生饱和失真样本，这与目标专利中的“饱和信号”和“经压缩传输”相关。本领域技术人员可以理解，为了降低PAPR，发送方会对信号进行幅度抑制处理，这相当于目标专利中的“经压缩传输”和“饱和信号”。 |
| 技术特征D：所述饱和信号是在不具有描述与所述饱和信号相关联的抑制峰值的峰值抑制信息的情况下传送的 | **《直接公开》** | 【0043】For data transmission on the downlink, upstream station 118 may be base station 130, and downstream station 122 may be wireless device 110. For data transmission on the uplink, upstream station 118 may be wireless device 110, and downstream station 122 may be base station 130. For both cases, data transmission may be sent with channel encoding and without PAPR encoding.<br>【0053】In one design, PAPR detector 550 may compare the computed PAPR against a PAPR threshold...If high PAPR is detected, then PAPR detector 550 may provide NACK Type 1. | 对比文件明确公开了在某些情况下，数据传输可以仅使用信道编码而不使用PAPR编码（即没有PAPR相关信息）。当中继站检测到高PAPR时，会发送NACK Type 1。这表明初始传输是在没有PAPR相关信息的情况下传送的，与目标专利中“在不具有描述与所述饱和信号相关联的抑制峰值的峰值抑制信息的情况下传送”相对应。 |
| 技术特征E：接收指示未能成功自主地还原包括饱和信号的所述经压缩传输的否定确收消息 | **《直接公开》** | 【0043】Relay station 120 may send NACK Type 1 to upstream station 118 if high PAPR is detected (step 3).<br>【0053】If high PAPR is detected, then PAPR detector 550 may provide NACK Type 1. Feedback information comprising NACK Type 1 may be processed...and transmitted to upstream station 118. | 对比文件明确公开了中继站检测到高PAPR时会向上一级站发送NACK Type 1否定确认消息。在放大转发(AF)模式下，中继站可以自主决定是否转发信号，当检测到高PAPR时不转发，这表明中继站在尝试自主处理但发现高PAPR问题时发送NACK。这与目标专利中的“指示未能成功自主地还原...的否定确收消息”相对应。 |
| 技术特征F：至少部分地基于接收到否定确收消息来传送重传以使得能够对所述经压缩传输进行失真还原 | **《直接公开》** | 【0043】Upstream station 118 may receive NACK Type 1 from relay station 120 and may adjust one or more transmission parameters to mitigate high PAPR (step 4). Upstream station 118 may send another HARQ transmission for the packet in response to receiving NACK Type 1 from relay station 120 (step 5).<br>【0065】FIG. 6 shows a design of a message flow 600 for data transmission via relay station 120 in the DF mode with NACK Type 1 and NACK Type 2. | 对比文件明确公开了当上游站接收到NACK Type 1后，会调整传输参数并发送另一次HARQ传输。这对应于目标专利中的“至少部分地基于接收到否定确收消息来传送重传”。 |
| 技术特征G：所述重传至少部分地基于接收到所述否定确收消息来指示所述峰值抑制信息 | **《隐含公开》** | 【0032】A receiver may receive and process the transmission of the packet and may send NACK Type 1 if PAPR encoding is performed by the transmitter and PAPR decoding by the receiver fails. The receiver may also send NACK Type 1 if PAPR encoding is not performed by the transmitter and high PAPR is detected by the receiver.<br>【0065】Relay station 120 may send NACK Type 1 to upstream station 118 if high PAPR is detected or PAPR decoding fails. | 对比文件公开了在PAPR编码/解码场景中，当PAPR解码失败或检测到高PAPR时会发送NACK Type 1。重传时上游站会调整传输参数，可能包括PAPR编码的调整。虽然对比文件没有明确说明重传包含峰值抑制信息，但本领域技术人员可以理解，在接收到关于PAPR问题的NACK后，重传可能会包含用于解决PAPR问题的相关信息。 |
| 技术特征H：其中所述重传包括标识所述经压缩传输的饱和峰值的信息 | **《隐含公开》** | 【0069】A PAPR encoder 712...may process each block of data symbols for PAPR reduction and may provide a corresponding block of output symbols having lower PAPR in an output signal. PAPR encoder 712 may implement a PAPR reduction technique such as selective mapping (SM), partial transmit sequences (PTS), etc. PAPR encoder 712 may provide side information, which may indicate the selected symbol sequence being transmitted. | 对比文件公开了PAPR编码器可以提供边信息(side information)，指示所选择的符号序列。这相当于目标专利中的“标识饱和峰值的信息”。本领域技术人员可以理解，边信息可用于在接收端还原原始信号峰值。 |
| 技术特征I：其中所述重传包括与增大所述经压缩传输的处理信噪比相关联的信息 | **《隐含公开》** | 【0043】Upstream station 118 may receive NACK Type 1 from relay station 120 and may adjust one or more transmission parameters to mitigate high PAPR (step 4). For example, upstream station 118 may increase the back-off of its power amplifier and may operate at a lower average transmit power level if high PAPR is detected in order to prevent clipping and reduce intermodulation distortion. | 对比文件公开了上游站可以增加功率放大器的回退(back-off)来减少互调失真。增加回退可以改变信号的功率特性，从而影响信噪比处理。这隐含公开了与增大处理信噪比相关联的信息。 |
| 技术特征J：其中未能成功自主地还原所述经压缩传输是校验和失败 | **《隐含公开》** | 【0054】Channel decoder 580 may also check the decoded packet based on the CRC for the packet to determine whether the packet is decoded correctly or in error. Channel decoder 580 may provide NACK Type 2 if the packet is decoded in error and may provide ACK if the packet is decoded correctly. | 对比文件公开了使用CRC（循环冗余校验）来检查解码后的数据包是否正确。CRC是校验和的一种形式。当CRC检查失败时，会发送NACK Type 2。这与目标专利中的“校验和失败”相关。 |
| 技术特征K：其中所述一个或多个处理器被进一步配置成：标识在传送所述重传之后未能还原所述经压缩传输 | **《隐含公开》** | 【0044】Downstream station 122 may receive the HARQ transmission from relay station 120 and may decode the packet based on the HARQ transmission (step 4). Downstream station 122 may send ACK if the packet is decoded correctly or NACK Type 2 if the packet is decoded in error (step 5). | 对比文件公开了下游站可以尝试解码数据包，并在解码错误时发送NACK Type 2。这表明存在标识解码失败（即未能还原经压缩传输）的机制。 |
| 技术特征L：至少部分地基于标识在传送所述重传之后未能还原所述经压缩传输而回落至混合自动重复请求重传规程 | **《直接公开》** | 【0026】System 100 may support hybrid automatic retransmission (HARQ) for data transmission on the downlink and/or the uplink in order to improve reliability of data transmission. For HARQ, a transmitter may send a transmission of a data packet to a receiver and may send one or more additional transmissions of the packet, if needed, until the packet is decoded correctly by the receiver, or the maximum number of transmissions has been sent for the packet, or some other termination condition is encountered.<br>【0044】Upstream station 118 may receive the ACK or NACK Type 2, may terminate transmission of the packet if ACK is received (not shown in FIG. 4B) and may send another HARQ transmission for the packet if NACK Type 2 is received (step 7). | 对比文件明确公开了系统支持HARQ混合自动重传请求机制，当接收到NACK时会发送另一次HARQ传输，这对应于目标专利中的“回落至混合自动重复请求重传规程”。 |
| 技术特征M：其中所述重传包括功率系统信息消息(PSIM) | **《未公开》** | 无相关引用 | 对比文件没有公开“功率系统信息消息(PSIM)”这一特定术语或概念。目标专利中的PSIM是指峰值抑制信息消息(Power Suppression Information Message)，用于承载峰值抑制信息。对比文件中虽然有关于PAPR编码/解码和边信息的描述，但没有使用PSIM这一特定术语或明确公开其作为重传来传输峰值抑制信息的机制。 |
