| 技术特征描述及公开性判断结果 | 对比文件原文引用 | 公开性论述 |
| **技术特征A**：在用户装备(UE)执行的随机接入规程期间从所述UE接收来自所述UE的至少两个天线的预编码器选择信号，所述预编码器选择信号中的至少一个预编码器选择信号包括来自所述UE的第一天线的第一测量参考信号(MRS) 《隐含公开》 | 第[0118]段：“In a system which may use beamforming in the DL and/or in the UL, initial or other access may be performed using Physical Random Access Channel (PRACH) and/or a random access procedure.” 第[0158]段：“In this embodiment, an mWTRU may perform a preamble transmission procedure which may be a fixed narrow antenna pattern preamble transmission procedure. BSRS may be substituted for Beam Measurement Reference Signal (BMRS)... A configuration may be provided and/or used. An mWTRU may receive a downlink BMRS transmission configuration and/or a RACH configuration.” 第[0159]段：“The mWTRU may sweep receive beams and/or perform measurements. The mWTRU may sweep one or more receive beams or antenna patterns which may be narrow receive beams or antenna patterns. The mWTRU may perform the sweep per the configured BMRS time and/or frequency resource schedule. The mWTRU may measure a BMRS according to a BMRS sequence.” 第[0160]段：“The mWTRU may transmit to the SCmB a preamble based on the maximum measured BMRS.” | 对比文件公开了在波束成形系统中进行随机接入（RA）规程，mWTRU（相当于UE）接收下行链路波束测量参考信号（BMRS，其功能与MRS类似，用于测量）配置，并在RA规程期间根据配置扫描接收波束并测量BMRS（相当于接收包含MRS的信号）。对比文件描述mWTRU扫描“一个或多个”窄接收波束/天线模式进行测量，结合其描述的mWTRU可具有多个RF链和天线端口的架构（例如第[0105]-[0106]段），本领域技术人员可以合理推断，为实现有效的波束测量和选择，mWTRU可能使用至少两个天线进行接收扫描和测量，从而隐含公开了从至少两个天线接收包含BMRS（MRS）的预编码器选择信号。 |
| **技术特征B**：至少部分地基于所述第一MRS和所接收的预编码器选择信号来确定精制预编码设置 《隐含公开》 | 第[0168]段：“In an embodiment, an SCmB may determine spatial AoD/AoA information based on a reported mWTRU beam measurement.” 第[0170]段：“The SCmB may evaluate possible transmission schemes for data transmissions to the reporting mWTRU.” 第[0177]段：“In another embodiment, the SCmB may schedule in common PDDCCH, one or more of the proposed transmission modes. A SCmB may send the transmission mode scheduling information in common or dedicated PDDCCH which includes but is not limited to: Transmission mode ..., transmit beam information ..., receive beam information ...” 第[0191]段：“The SCmB may form a narrow transmit beam at the AoD corresponding to the AoA path with the highest reported quality metric ...” | 对比文件公开了SCmB（相当于网络接入设备）基于mWTRU报告的波束测量结果（该结果基于对BMRS等参考信号的测量）来确定空间角度信息（AoD/AoA），并评估和选择数据传输方案（传输模式），调度信息中包含传输波束信息等。确定用于数据传输的“传输波束”本质上就是确定一种“预编码设置”。SCmB基于UE的测量报告（该报告源于对BMRS/MRS的测量）来选择/确定传输波束，这隐含公开了“至少部分地基于所接收的预编码器选择信号（即测量报告所基于的BMRS/MRS测量）来确定精制预编码设置（即选择的传输波束）”。 |
| **技术特征C**：向所述UE传送所述精制预编码设置的指示 《隐含公开》 | 第[0177]段：“... A SCmB may send the transmission mode scheduling information in common or dedicated PDDCCH which includes but is not limited to: Transmission mode ..., transmit beam information ..., receive beam information ...” 第[0190]段：“In another embodiment, an mWTRU may decode the transmission mode scheduling information on the common PDDCCH, dedicated PDDCCH or LTE PDCCH. The mWTRU may receive a directional HARQ transmission scheduling ...” 第[0191]段：“The SCmB may form a narrow transmit beam at the AoD corresponding to the AoA path with the highest reported quality metric and transmit the PDDDCH new transmission.” | 对比文件公开了SCmB通过公共或专用PDDCCH向mWTRU发送传输模式调度信息，该信息包括传输波束信息、接收波束信息等。这些信息指示了用于数据传输的波束方向，实质上就是“精制预编码设置的指示”。mWTRU解码该调度信息并据此进行接收或传输，例如形成对应的接收波束。因此，对比文件隐含公开了向UE传送精制预编码设置（以传输波束信息等形式）的指示。 |
| **技术特征D**：其中，所述预编码器选择信号中的至少一个预编码器选择信号包括来自所述UE的第二天线的第二MRS 《隐含公开》 | 第[0159]段：“The mWTRU may sweep one or more receive beams or antenna patterns which may be narrow receive beams or antenna patterns. ... The mWTRU may measure a BMRS according to a BMRS sequence.” 第[0106]段：“... hybrid approach including analogue beamforming performed over the phase array antenna elements ... and digital precoding applied on the baseband signal of each RF chain when there is more than one RF chain.” | 对比文件描述mWTRU在测量时扫描“一个或多个”接收波束/天线模式。为了全面评估空间信道，mWTRU通常会利用其多个天线或天线端口进行扫描测量。结合对比文件描述的mWTRU可具有多个RF链和天线端口的混合波束成形架构，本领域技术人员可以合理推断，在扫描测量BMRS（MRS）的过程中，可能会从多个天线（例如与不同RF链或天线端口关联的天线）接收测量信号，从而隐含公开了预编码器选择信号可能包括来自第二天线的第二MRS。 |
| **技术特征E**：其中，所述第一MRS是与以下至少一者一起被接收的：物理随机接入信道(PRACH)传输、或增强型PRACH(ePRACH)传输、或初始物理上行链路共享信道(PUSCH)传输、或其组合 《隐含公开》 | 第[0158]段：“... An mWTRU may receive a downlink BMRS transmission configuration and/or a RACH configuration. The configuration or configurations may be received from an SCmB. The configuration or configurations may be received in higher layer signaling such as in a SIB or SIBs ... The RACH configuration may comprise of a mapping between BMRS sequence or index ... and one or more ... parameters for a RACH or preamble transmission ...” 第[0159]段：“The mWTRU may sweep one or more receive beams ... per the configured BMRS time and/or frequency resource schedule. The mWTRU may measure a BMRS according to a BMRS sequence.” | 对比文件公开了BMRS（MRS）配置与RACH（随机接入信道）配置之间的映射关系。mWTRU根据配置的BMRS时间和频率资源调度来测量BMRS，并基于测量结果选择对应的RACH前置码进行传输。这意味着BMRS的测量是与随机接入规程紧密关联的。虽然对比文件未明确BMRS是与PRACH/ePRACH/PUSCH传输“一起”被接收，但BMRS作为用于波束配对和RA资源选择的测量信号，其接收是RA规程准备阶段的一部分。本领域技术人员可以合理推断，网络设备可能在接收RA前置码（PRACH）或后续上行数据（类似PUSCH）的相同或相关联的时空资源上，接收并利用这些测量信号（或其反馈报告）来进行波束精制，从而隐含公开了MRS与RA相关传输一起被接收的概念。 |
| **技术特征F**：进一步包括：在所述随机接入规程期间从所述UE接收至少部分地基于所述精制预编码设置的指示而使用第一预编码器或者使用所述UE在先前成功的随机接入规程期间使用的第二预编码器的ePRACH传输或初始PUSCH传输 《隐含公开》 | 第[0190]段：“In another embodiment, an mWTRU may decode the transmission mode scheduling information on the common PDDCCH, dedicated PDDCCH or LTE PDCCH. The mWTRU may receive a directional HARQ transmission scheduling and upon decoding an error of the HARQ new data transmission perform beam pair switch for one or all HARQ retransmissions according to the scheduled transmit and/or receive beam indices.” 第[0199]段：“The SCmB may reconfigure the HARQ directional transmission to a regular HARQ transmission when receiving a pre-defined consecutive number of NACKs for new transmissions and ACKs for retransmissions. The SCmB may set the transmission scheme selection field ... to a bit combination corresponding to the regular transmission mode and use the transmit and/or receive beam for HARQ retransmission for HARQ new transmissions.” | 对比文件公开了mWTRU基于接收到的定向HARQ传输调度信息（其中包含调度的波束索引，相当于精制预编码设置的指示），在解码新数据传输失败时，根据该调度切换波束对进行重传。这体现了基于网络指示使用特定波束（预编码器）进行传输。此外，第[0199]段提到SCmB在特定条件下将重传使用的波束（第二预编码器）重新配置用于新的传输，这隐含了可能使用先前成功传输（重传成功）所使用的预编码器。虽然对比文件具体涉及HARQ重传，但其原理（基于网络指示选择波束/预编码器进行上行传输）可以合理延伸至ePRACH或初始PUSCH传输场景。因此，该特征被隐含公开。 |
| **技术特征G**：进一步包括：传送所述精制预编码设置的指示以应用于所述随机接入规程期间的传输 《隐含公开》 | 第[0177]段：“... A SCmB may send the transmission mode scheduling information in common or dedicated PDDCCH which includes but is not limited to: Transmission mode ..., transmit beam information ..., receive beam information ...” 第[0190]段：“... The mWTRU may receive a directional HARQ transmission scheduling ... perform beam pair switch for one or all HARQ retransmissions according to the scheduled transmit and/or receive beam indices.” | 对比文件公开了SCmB发送包含传输波束信息的调度信息，且mWTRU根据该调度信息执行波束对切换以进行重传。这表明网络指示的波束设置（精制预编码设置）被应用于正在进行的数据传输（HARQ重传是RA规程后数据传输的一部分，可视为在RA规程建立的连接期间的传输）。本领域技术人员可以理解，这种基于网络指示应用特定波束进行传输的机制，同样可以应用于随机接入规程期间的其他上行传输。因此，该特征被隐含公开。 |
| **技术特征H**：进一步包括：传送所述精制预编码设置的指示以应用于在所述随机接入规程之后的传输 《隐含公开》 | 第[0199]段：“The SCmB may reconfigure the HARQ directional transmission to a regular HARQ transmission when receiving a pre-defined consecutive number of NACKs for new transmissions and ACKs for retransmissions. The SCmB may set the transmission scheme selection field in common or dedicated PDDCCH to a bit combination corresponding to the regular transmission mode and use the transmit and/or receive beam for HARQ retransmission for HARQ new transmissions.” | 对比文件公开了SCmB在特定条件下，通过设置传输模式选择字段，指示mWTRU将用于HARQ重传的波束（即一种精制后的波束设置）应用于后续的HARQ新传输。这明确体现了将精制预编码设置的指示应用于在当前传输（重传）之后的传输（新传）。虽然场景是HARQ过程，但该原理“将一次传输中确定的较好设置应用于后续传输”同样适用于随机接入规程之后的传输。因此，该特征被隐含公开。 |
| **技术特征I**：进一步包括：在执行所述随机接入规程期间，传送包括以下至少一者的传输：随机接入响应(RAR)准予、用于所述UE的初始物理上行链路共享信道(PUSCH)传输的下行链路控制信息(DCI)调度信息、或其组合 《直接公开》 | 第[0301]段：“The mWTRU may receive an RA response in the SCmB downlink transmit beam ... In the determined RA response window start frame, sub-frame, TTI, or symbol, the mWTRU may decode a downlink control channel using RA-RNTI or C-RNTI to receive RA response scheduling information.” 第[0302]段：“The RA response may be carried in a downlink data channel beam ... An mWTRU may detect a downlink control channel using RA-RNTI or C-RNTI in the determined RA response window and successfully decode the downlink data channel in the scheduled downlink data channel beam. The mWTRU may successfully decode the downlink data channel and may receive uplink control and/or data channel scheduling information, uplink transmission timing information, etc.” 第[0303]段：“The mWTRU may transmit the scheduled uplink control and/or data channel using the mWTRU uplink transmit beam applied for the corresponding PRACH transmission.” | 对比文件明确描述了在随机接入规程期间，mWTRU在RA响应窗口内解码下行控制信道以接收RA响应调度信息，并且RA响应承载于下行数据信道中，其中包含上行控制/数据信道调度信息。这里的“RA响应”即RAR，“上行控制/数据信道调度信息”即用于初始上行共享信道（如PUSCH）传输的调度准予，其内容与DCI调度信息功能一致。因此，对比文件直接公开了在执行随机接入规程期间，传送包括RAR和上行调度准予的传输。 |
| **技术特征J**：其中，所述传输包括至少一个预编码器选择信号参数，所述至少一个预编码器选择信号参数包括：所述预编码器选择信号的带宽、所述预编码器选择信号的循环移位、传送所述预编码器选择信号的天线端口数目、或其组合 《隐含公开》 | 第[0250]段：“An RA resource set may include a PRACH format for use with one or more, including all, of the preambles in the RA resource set. The PRACH format may indicate preamble transmission parameters such as the duration of the PRACH transmission in number of symbols, a number of TTIs, or a number of sub-frames, the length of a guard period, the length of a cyclic prefix, etc.” 第[0252]段：“Transmission and/or RA procedure parameters which may be associated with an RA resource set may include one or more of the following: a PRACH maximum power, a PRACH minimum transmit beamforming gain, a PRACH maximum transmit bandwidth, an SCmB antenna gain offset, an initial PRACH receive target power, or a power offset between the PRACH and an uplink control and/or data channel TDD configuration indication.” | 对比文件详细描述了RA资源集包含PRACH格式以及其他传输/RA过程参数，这些参数定义了上行PRACH传输的各方面特性，例如最大传输带宽（隐含带宽参数）、循环前缀长度（与循环移位概念相关，均涉及序列的循环特性）、以及与波束成形相关的增益和功率参数（与天线端口数目和波束成形配置间接相关）。虽然未明确列出“预编码器选择信号参数”这一集合，但本领域技术人员可以理解，网络在调度或配置上行参考信号（如用于预编码器选择的SRS/MRS）时，需要指定其传输参数，如带宽、循环移位、天线端口等。对比文件公开的RA相关参数配置机制，为隐含公开这些具体的预编码器选择信号参数提供了基础。 |
| **技术特征K**：其中，所述传输包括所述精制预编码设置的指示 《隐含公开》 | 第[0177]段：“... A SCmB may send the transmission mode scheduling information in common or dedicated PDDCCH which includes but is not limited to: Transmission mode ..., transmit beam information ..., receive beam information ...” | 如对特征C和I的论述，对比文件公开了在公共或专用PDDCCH（一种下行控制信道传输）中发送传输模式调度信息，该信息包含传输波束信息等，即精制预编码设置的指示。虽然该描述可能不特指RAR传输，但下行控制信道传输（如用于调度RAR或上行许可的PDCCH/PDDCCH）可以承载此类指示。因此，该特征被隐含公开。 |
| **技术特征L**：进一步包括：从所述UE接收根据所指示的精制预编码设置的至少一个传输，所述至少一个传输包括：初始PUSCH传输、所述初始PUSCH传输的重传、或其组合 《隐含公开》 | 第[0303]段：“The mWTRU may transmit the scheduled uplink control and/or data channel using the mWTRU uplink transmit beam applied for the corresponding PRACH transmission.” 第[0190]段：“... perform beam pair switch for one or all HARQ retransmissions according to the scheduled transmit and/or receive beam indices.” | 对比文件公开了mWTRU使用与对应PRACH传输相关的上行传输波束来发送调度的上行控制/数据信道，以及根据调度信息进行波束对切换以进行重传。这体现了UE根据网络指示的波束设置（精制预编码设置）进行上行传输。虽然对比文件未明确使用“初始PUSCH传输”这一术语，但“调度的上行控制/数据信道”包含了初始上行共享信道传输的概念。因此，该特征被隐含公开。 |
