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.<br><br>[0024] 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. | 对比文件公开了传送数据包的传输的技术，但**未明确公开**包括“饱和信号”的“经压缩传输”这一特定技术特征。对比文件提到PAPR（峰均功率比）和PAPR编码，但没有明确描述“饱和信号”或“经压缩传输”的概念与目标专利中的含义相同。虽然涉及PAPR相关传输，但并非目标专利中特指的饱和信号传输。**未直接公开** |
| 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 | [0035] Relay station 120 may receive the HARQ transmission and may determine the PAPR of the HARQ transmission (step 2). Relay station 120 may send NACK Type 1 to upstream station 118 if high PAPR is detected (step 3). In one design, relay station 120 may skip forwarding the HARQ transmission to downstream station 122 if high PAPR is detected, as shown in FIG. 4A.<br><br>[0036] Downstream station 122 may receive the HARQ transmission from relay station 120 and may decode the packet based on the HARQ transmission (step 4). | 对比文件描述了中继站检测高PAPR并发送NACK Type 1的流程，但**未明确公开**“在不具有峰值抑制信息的情况下传送饱和信号”这一目标专利特定技术方案。对比文件中的传输是在中继站检测PAPR并反馈NACK，而不是设备主动在不包含峰值抑制信息的情况下传送饱和信号。**未直接公开** |

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><br>[0008] The relay station may send a NACK to the upstream station if high PAPR is detected. The upstream station may send another transmission of the packet in response to receiving the NACK from the relay station. | 对比文件公开了接收NACK并响应发送重传的技术特征。上游站（基站）接收中继站发送的NACK Type 1，然后发送另一个HARQ传输作为响应。该技术特征与目标专利中“接收...否定确收消息...至少部分地基于接收到否定确收消息来传送重传”的技术方案实质相同。虽然NACK的原因不同，但技术方案的核心（接收NACK并触发重传）被直接公开。**直接公开** |
| 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 | [0035] Upstream station 118 may receive NACK Type 1 from relay station 120... 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><br>[0008] The upstream station may send another transmission of the packet in response to receiving the NACK from the relay station. | 对比文件明确公开了基于接收NACK而传送重传的技术方案。上游站接收NACK后，发送另一个HARQ传输作为响应。该技术特征与目标专利中“至少部分地基于接收到否定确收消息来传送重传”的技术方案完全相同。**直接公开** |
| 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 | [0058] 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），但这是指序列选择信息，而非目标专利中的“峰值抑制信息”。目标专利中的峰值抑制信息是用于还原由消波施加的失真的特定信息，而对比文件中的side information是关于PAPR编码序列选择的信息。两者作用不同。**未直接公开** |
| 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 | [0058] 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. | 对比文件提到了side information，但该信息是关于PAPR编码序列选择的信息，不是“标识饱和峰值的信息”。目标专利中的重传包含用于还原饱和信号失真的峰值抑制信息（位置、幅度等），而对比文件的side information是编码序列指示信息。两者本质不同。**未直接公开** |
| 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 | 对比文件中未找到相关内容 | 对比文件主要讨论PAPR检测和NACK反馈机制，没有公开“与增大处理信噪比相关联的信息”这一技术特征。**未直接公开** |
| 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 | [0043] 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.<br><br>[0045] In one design, upstream station 118 may send another HARQ transmission for the packet if NACK Type 1 is received from relay station 120 or NACK Type 2 is received from downstream station 122. | 对比文件公开了使用CRC进行校验和检查以确定解码是否成功的技术。信道解码器580基于CRC检查解码后的数据包，以确定数据包是否正确解码或错误解码。如果解码错误，则提供NACK Type 2。该技术特征与目标专利中“未能成功自主地还原...是校验和失败”的技术方案实质相同。CRC校验失败即对应校验和失败。**直接公开** |
| 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 | [0043] 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.<br><br>[0045] Upstream station 118 may send another HARQ transmission for the packet if NACK Type 1 is received from relay station 120 or NACK Type 2 is received from downstream station 122. | 对比文件公开了在接收到NACK Type 2（解码错误）后，上游站可发送另一个HARQ传输。虽然没有明确描述“标识在传送重传之后未能还原”的完整流程，但通过CRC检查确定解码错误并触发额外传输的机制隐含了该技术特征。**隐含公开** |

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. | 对比文件公开了HARQ机制作为标准重传规程。在HARQ中，发射机可以发送数据包的多个传输，直到数据包被接收机正确解码或达到最大传输次数。目标专利中“回落至混合自动重复请求重传规程”与对比文件中的HARQ机制实质相同。**直接公开** |
| 技术特征M：其中所述重传包括功率系统信息消息(PSIM) | 对比文件中未找到PSIM相关内容 | 对比文件讨论的是PAPR（峰均功率比）相关的编码和解码，以及NACK Type 1和NACK Type 2的反馈机制，但没有提到“功率系统信息消息(PSIM)”这一术语或类似概念。**未直接公开** |
