### 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**：包括：一个或多个存储器 | **[0027]** "Memories 332, 362 and 392 may store data and program codes for wireless device 110, relay station 120, and base station 130, respectively." | 对比文件明确公开了无线通信设备包括存储器组件。虽然对比文件描述的是中继站场景下的存储器，但技术领域与目标专利相同(无线通信)，本领域技术人员能够毫无疑义地理解存储器是通信设备的必要组成部分。 |
| **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 | **[0027]** "Controllers/processors 330, 360 and 390 may control the operation at wireless device 110, relay station 120, and base station 130, respectively." | 对比文件公开了控制器/处理器与存储器的配置关系，结合[0079]提到的"处理器和存储介质"的组合实现，本领域技术人员可以明确理解处理器与存储器的耦合关系。 |
| **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 | **[0019]** "To limit the amount of intermodulation distortion, a power amplifier may be operated at an average power level that is backed off from the maximum power level of the power amplifier."<br>**[0020]** "A transmitter may send a transmission of a data packet with channel encoding and either with or without PAPR encoding." | 对比文件描述了功率放大器操作在低于最大功率水平的状态以限制失真，这与目标专利中"饱和信号"的概念相关。对比文件中的传输涉及PAPR编码(压缩)处理，但未明确使用"饱和信号"和"经压缩传输"的术语。考虑到技术领域相同，且对比文件公开的功率放大器操作概念与目标专利的饱和信号传输在技术实质上相关，应判断为隐含公开。 |
| **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 | **[0030]** "For both cases, data transmission may be sent with channel encoding and without PAPR encoding." | 对比文件明确公开了数据传输可以采用信道编码而不采用PAPR编码的方式。这与目标专利中"在不具有峰值抑制信息的情况下传送饱和信号"的技术特征相对应，即初始传输不携带PSIM信息。 |
| **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 | **[0005]** "The relay station may send NACK Type 2 to the upstream station if the packet is decoded in error."<br>**[0020]** "The receiver 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." | 对比文件详细公开了NACK Type 1(因高PAPR或PAPR解码失败)和NACK Type 2(因信道解码错误)的否定确认机制。这些NACK消息指示了接收端未能成功还原传输数据，与目标专利的"否定确收消息"功能一致。 |
| **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 | **[0020]** "The transmitter may generate another transmission of the packet with different PAPR encoding and/or different channel encoding if NACK Type 1 or NACK Type 2 is received and may send this transmission of the packet to the receiver."<br>**[0056]** "Upstream station 118 may control data transmission based on the feedback information. For example, upstream station 118 may generate another HARQ transmission with (i) new PAPR encoding if NACK Type 1 is received or (ii) new channel encoding and new PAPR encoding if NACK Type 2 is received." | 对比文件明确公开了基于NACK反馈进行重传的机制，特别是生成具有不同PAPR编码和/或信道编码的额外传输，这使得接收端能够对原始传输进行失真还原。 |
| **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 | **[0054]** "PAPR encoder 712 may implement a PAPR reduction technique such as selective mapping (SM), partial transmit sequences (PTS), etc."<br>**[0055]** "PAPR decoder 748 (which may be part of receive processor 350 in FIG. 3) may perform PAPR decoding on the received symbols in a manner complementary to the PAPR encoding performed by upstream station 118." | 对比文件公开了在重传中包含PAPR编码侧信息的机制，侧信息(如选择性映射中选择的符号序列)可被理解为峰值抑制信息的一部分，用于辅助解码还原。 |
| **技术特征H**：所述重传包括标识所述经压缩传输的饱和峰值的信息 | **[0055]** "The PAPR decoding may be performed (i) based on the side information if sent by upstream station 118 or (ii) blindly for all possible symbol sequences that could have been transmitted." | 对比文件公开了PAPR解码可基于侧信息执行，而侧信息(如选择性映射中的序列选择)标识了与峰值抑制相关的信息，这与目标专利中"标识饱和峰值的信息"在技术实质上相同。 |
| **技术特征I**：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 | **[0038]** "For example, the PAPR threshold may be set based on decoding capability of a channel decoder 580 in downstream station 122. The PAPR threshold may also be set based on channel conditions observed by downstream station 122, the back-off of power amplifier 514 in upstream station 118, and/or other criteria." | 对比文件描述了PAPR阈值可根据信道解码能力、信道条件、功率放大器回退等因素设定，这些因素与增大处理信噪比相关联，隐含公开了重传中包含与信噪比相关的信息。 |
| **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 | **[0039]** "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."<br>**[0055]** "Channel decoder 750 may also check the decoded packet based on the CRC for that packet to determine whether the packet is decoded correctly or in error." | 对比文件明确公开了使用CRC(循环冗余校验)进行数据包校验的机制，CRC检查失败即对应于"校验和失败"，这与目标专利的技术特征完全一致。 |
| **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 | **[0005]** "The relay station may send NACK Type 2 to the upstream station if the packet is decoded in error."<br>**[0014]** "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." | 对比文件公开了HARQ机制，其中接收方在解码失败时发送NACK，上游站可据此判断重传后仍未能成功还原传输。结合[0005]和[0014]的描述，隐含公开了标识重传后解码失败的技术特征。 |
| **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 | **[0014]** "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>**[0052]** "Upstream station 118 may send another HARQ transmission for the packet if NACK Type 1 or NACK Type 2 is received from relay station 120 or downstream station 122." | 对比文件明确公开了HARQ重传规程，当NACK被接收时触发额外的HARQ传输，这与目标专利的"回落至混合自动重复请求重传规程"在技术实质上相同。 |
| **技术特征M**：其中所述重传包括功率系统信息消息(PSIM) | 对比文件中未发现"PSIM"、"Peak Suppression Information Message"或"功率系统信息消息"的明确表述 | 对比文件虽然公开了PAPR编码、PAPR解码、侧信息等与峰值抑制相关的技术，但未使用"功率系统信息消息(PSIM)"这一特定术语。对比文件涉及的是PAPR(峰均功率比)的相关技术，而目标专利的PSIM是专门定义的消息类型。 |

### 综合分析结论
对比文件EP27530066A1主要涉及中继站场景下的PAPR(峰均功率比)检测与ACK/NACK反馈机制，与目标专利CN115943581B的PSIM(峰值抑制信息消息)作为重传的技术方案在技术领域上具有相关性，但存在以下关键差异：
1. **技术方案定位不同**：对比文件侧重于中继站的PAPR检测与反馈，目标专利侧重于UE与基站之间的PSIM重传机制
2. **核心概念差异**：对比文件使用"PAPR encoding/decoding"和"side information"，而目标专利定义了专门的"PSIM(功率系统信息消息)"
3. **应用场景差异**：对比文件主要涉及放大-转发(AF)和译码-转发(DF)中继模式，目标专利涉及直接通信场景下的饱和信号传输与失真还原
