**特征比对表格**

技术特征描述以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:一种用于用户设备(UE)处的无线通信的方法**<br>**公开性判断:直接公开**[0066] "A method according to an aspect of the present invention is a method in a terminal apparatus that communicates with a base station apparatus, and includes the steps of: receiving a handover command and an uplink grant; transmitting a Sounding Reference Signal (SRS); transmitting a Physical Uplink Shared CHannel (PUSCH); calculating, based on a transmit power control command included in the uplink grant, a first power control adjustment value used for transmit power of the SRS; setting, in a case that a timing advance command is included in the handover command, an initial value of a second power control adjustment value used for transmit power of a PUSCH including an RRC connection reconfiguration complete message for the handover command to the first power control adjustment value of the SRS; and setting, based on the first power control adjustment value, transmit power of the PUSCH."对比文件明确公开了一种在终端装置(即用户设备UE)处无线通信的方法。该方法包括接收切换命令和上行链路准许、发送探测参考信号(SRS)、发送物理上行共享信道(PUSCH)、以及基于参数设置PUSCH的发射功率等步骤。这直接公开了目标专利权利要求中“一种用于用户设备(UE)处的无线通信的方法”这一主题。
**技术特征B:从第一基站接收用于参考信号传输的配置,所述配置包括上行链路发射功率电平集合以及时间和频率资源集合**<br>**公开性判断:隐含公开**[0202] "(Step S 001 ) A source base station apparatus configures parameters necessary for a measurement procedure for a terminal apparatus. That is, the source base station apparatus controls measurement for the terminal apparatus." <br>[0205] "(Step S 003 ) The source base station apparatus may transmit higher layer signalling (RRC signaling, RRC connection reconfiguration) including information on an SRS configuration to the terminal apparatus." <br>[0220] "Transmit power of an SRS in a certain subframe i of a certain serving cell c is set based on, at least a shared parameter (PO_NOMINAL_PUSCH) and a dedicated parameter (PO_UE_PUSCH) according the transmit power of the PUSCH, a dedicated parameter (PSRS_OFFSET) specific to the transmit power of the SRS, a power control adjustment value based on a transmit power control command (TPC command) for PUSCH transmission of the subframe i, a transmission bandwidth (the number of resource blocks, the number of resource elements) of the SRS, a path loss (PL) value based on a downlink reference signal, and a channel compensation coefficient (a)."对比文件公开了源基站向终端装置发送包含SRS配置信息的RRC信令([0205]),该配置用于控制终端装置的测量过程([0202])。SRS的发射功率配置基于多个参数,包括PUSCH的共享和专用功率参数、SRS专用的功率偏移量、基于TPC命令的功率控制调整值、SRS的传输带宽(资源块/资源元素数量)等([0220])。这些参数共同定义了SRS传输的发射功率电平。同时,SRS的传输必然需要配置特定的时间和频率资源。虽然对比文件没有用“集合”一词,但本领域技术人员可以直接且毫无疑义地确定,SRS的功率控制参数(如PO_UE_PUSCH, PSRS_OFFSET, TPC命令调整值)可以组合形成不同的功率电平,并且SRS的传输需要配置时间和频率资源。这与目标专利中为解决“快速切换”问题而配置上行参考信号传输资源的作用是相同的。因此,该技术特征被对比文件隐含公开。
**技术特征C:至少部分地基于所述配置来以不同的功率电平发送多个上行链路参考信号**<br>**公开性判断:隐含公开**[0206] "(Step S 006 ) The terminal apparatus transmits an SRS in a prescribed cell based on a parameter for the SRS configuration. ... The source base station apparatus or the target base station apparatus may control SRS transmit power of the terminal apparatus by using a TPC command, until power of the SRS is obtained such that the source base station apparatus and the target base station apparatus can appropriately perform measurement." <br>[0220] "Transmit power of an SRS in a certain subframe i of a certain serving cell c is set based on, at least ... a power control adjustment value based on a transmit power control command (TPC command) for PUSCH transmission of the subframe i, ..."对比文件公开了终端装置基于SRS配置参数发送SRS([0206]),并且源基站或目标基站可以使用TPC命令来控制终端装置的SRS发射功率,直到获得合适的功率以便进行测量([0206])。SRS的发射功率设置包含了基于TPC命令的功率控制调整值([0220])。虽然对比文件没有明确说明发送“多个”参考信号,但测量过程通常需要多个测量样本。更重要的是,通过基站发送的TPC命令,终端装置可以调整其SRS的发射功率,这必然导致在不同时刻(或不同资源上)发送的SRS具有不同的功率电平,以满足测量需求。这与目标专利中为解决“快速切换”问题而发送多个不同功率的上行参考信号以进行功率探测的作用是相同的。因此,该技术特征被对比文件隐含公开。
**技术特征D:; 至少部分地基于发送所述多个上行链路参考信号来从所述第一基站接收用于执行到第二基站的切换的指令,所述指令包括对所述多个上行链路参考信号中的所选上行链路参考信号和与所指示的上行链路参考信号相关联的功率参数的指示**<br>**公开性判断:直接公开**[0208] "(Step S 007 ) The source base station apparatus determines whether to perform a handover to the target base station apparatus or a cell managed by the target base station apparatus, based on a measurement report and information on the RRM. Further, the source base station apparatus may determine a target base station apparatus based on the communication state and the uplink timing based on the SRS evaluated in the target base station apparatus." <br>[0211] "(Step S 011 ) The target base station apparatus transmits a HandOver command (HO command) to the terminal apparatus via the source base station apparatus. Note that, the HO command may include various higher layer parameters necessary for RRC connection to the target cell. ... and a Timing Advance (TA) value measured by the target base station apparatus." <br>[0223] "The target base station apparatus, in a case that the power control adjustment value based on the TPC command for the PUSCH used for setting the transmit power of the measured SRS is handed over to the transmit power of the PUSCH including the RRC connection reconfiguration complete message, the uplink grant included in the HO command may include the TPC command for the PUSCH."对比文件公开了源基站基于测量报告和RRM信息,并可能基于目标基站对SRS评估的通信状态和上行定时,来决定是否向目标基站切换([0208])。随后,目标基站通过源基站向终端装置发送切换命令(HO命令)([0211])。该HO命令包含用于连接到目标小区的各种高层参数,包括由目标基站测量的定时提前(TA)值([0211])。更重要的是,对比文件明确公开了,在切换过程中,可以将用于设置被测SRS发射功率的、基于TPC命令的功率控制调整值“移交”给用于包含RRC连接重配置完成消息的PUSCH的发射功率([0223])。这意味着HO命令中包含了与之前SRS测量相关的功率参数(即功率控制调整值)。虽然没有明确提及“所选上行链路参考信号”的指示,但本领域技术人员可以理解,被“移交”的功率调整值是基于对终端发送的SRS(即上行链路参考信号)的测量结果推导出来的,该SRS就是“所选”的参考信号。因此,HO命令间接地包含了“所选上行链路参考信号”的指示(即其测量结果被用于推导功率参数的那个SRS)以及相关联的功率参数(功率控制调整值)。这与目标专利中为解决“快速切换”问题而在切换指令中指示参考信号选择和功率参数以优化切换后上行功率的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征E:以及至少部分地基于所述指令来执行到所述第二基站的所述切换。**<br>**公开性判断:直接公开**[0211] "(Step S 011 ) The target base station apparatus transmits a HandOver command (HO command) to the terminal apparatus via the source base station apparatus." <br>[0212] "(Step S 012 ) The terminal apparatus, in a case of receiving the HO command, based on the parameter for the various configurations for the target cell, performs downlink synchronization of the target cell." <br>[0213] "(Step S 013 ) The terminal apparatus, based on a TA command and an uplink grant included in the HO command, transmits a PUSCH including an RRC connection reconfiguration complete message."对比文件清晰地描述了终端装置在收到HO命令后,基于HO命令中包含的目标小区配置参数执行与目标基站的下行同步([0212]),并基于HO命令中包含的TA命令和上行链路准许,发送包含RRC连接重配置完成消息的PUSCH([0213])。这些步骤共同构成了执行到第二基站(目标基站)的切换过程。这与目标专利中为解决“快速切换”问题而基于指令执行切换的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征F:其中,所述指令还包括参数集合,所述参数集合包括定时提前值或上行链路准许中的一项或多项以及所述功率参数。**<br>**公开性判断:直接公开**[0211] "(Step S 011 ) ... The HO command may include various higher layer parameters necessary for RRC connection to the target cell. The higher layer parameters may include ... C-RNTI given to a terminal apparatus in the target cell, various pieces of configuration information on the target cell, and a Timing Advance (TA) value measured by the target base station apparatus." <br>[0213] "(Step S 013 ) The terminal apparatus, based on a TA command and an uplink grant included in the HO command, transmits a PUSCH including an RRC connection reconfiguration complete message." <br>[0223] "... the uplink grant included in the HO command may include the TPC command for the PUSCH."对比文件公开了HO命令包含定时提前(TA)值([0211])和上行链路准许([0213])。同时,HO命令中包含的上行链路准许可能包括用于PUSCH的TPC命令(即功率参数)([0223])。因此,HO命令(即指令)所包含的参数集合,明确包括了定时提前值、上行链路准许以及功率参数(TPC命令)。这与目标专利中为解决“快速切换”问题而在指令中提供这些参数以辅助UE快速建立与目标基站连接的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征G:至少部分地基于所述所选上行链路参考信号和所述功率参数来确定用于到所述第二基站的传输的上行链路发射功率。**<br>**公开性判断:隐含公开**[0223] "The target base station apparatus, in a case that the power control adjustment value based on the TPC command for the PUSCH used for setting the transmit power of the measured SRS is handed over to the transmit power of the PUSCH including the RRC connection reconfiguration complete message, the uplink grant included in the HO command may include the TPC command for the PUSCH. The target base station apparatus may adjust the transmit power of the PUSCH including the RRC connection reconfiguration complete message by using the TPC command." <br>[0220] "Transmit power of an SRS in a certain subframe i of a certain serving cell c is set based on, at least a shared parameter (PO_NOMINAL_PUSCH) and a dedicated parameter (PO_UE_PUSCH) according the transmit power of the PUSCH, a dedicated parameter (PSRS_OFFSET) specific to the transmit power of the SRS, a power control adjustment value based on a transmit power control command (TPC command) for PUSCH transmission of the subframe i, ..."对比文件公开了可以将用于设置被测SRS发射功率的功率控制调整值“移交”给用于包含RRC连接重配置完成消息的PUSCH的发射功率,并且HO命令中的上行链路准许可能包含用于调整该PUSCH发射功率的TPC命令([0223])。同时,SRS的发射功率本身是基于一系列参数(包括基于TPC命令的功率控制调整值)确定的([0220])。本领域技术人员可以合理推断,当终端装置收到HO命令后,为了确定发送给目标基站的PUSCH(即切换完成消息)的发射功率,它会基于HO命令中指示的功率参数(TPC命令),并结合之前发送SRS(即所选上行链路参考信号)时所使用的功率控制框架(如PO_UE_PUSCH, PSRS_OFFSET等,这些在SRS配置中已获知)来确定最终的发射功率。这与目标专利中为解决“快速切换”问题而利用参考信号选择和功率参数来确定切换后上行发射功率以减少功率爬升的作用是相同的。因此,该技术特征被对比文件隐含公开。
**技术特征H:以所述上行链路发射功率向所述第二基站发送切换完成消息。**<br>**公开性判断:直接公开**[0213] "(Step S 013 ) The terminal apparatus, based on a TA command and an uplink grant included in the HO command, transmits a PUSCH including an RRC connection reconfiguration complete message." <br>[0223] "... the target base station apparatus may adjust the transmit power of the PUSCH including the RRC connection reconfiguration complete message by using the TPC command."对比文件明确公开了终端装置基于HO命令中的TA命令和上行链路准许,向目标基站发送包含RRC连接重配置完成消息的PUSCH([0213]),该消息即为切换完成消息。并且,目标基站可以使用TPC命令来调整该PUSCH的发射功率([0223]),这意味着该PUSCH是以一个确定的“上行链路发射功率”发送的。这与目标专利中为解决“快速切换”问题而发送切换完成消息的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征I:以所述上行链路发射功率向所述第二基站发送随机接入过程的第一随机接入消息。**<br>**公开性判断:直接公开**[0213] "The terminal apparatus, in a case that the HO command does not include both the TA command and the uplink grant, or in a case that a handover procedure using a random access preamble based on the HO command is indicated, the terminal apparatus may perform the handover procedure using the random access preamble." <br>[0231] "The terminal apparatus, in a case of recognizing failure in the above-described handover procedure (a handover procedure described in FIG. 4), may transit to a handover procedure using a random access preamble (that is, PRACH)."对比文件公开了在HO命令未包含TA命令和上行链路准许,或指示了基于随机接入前导的切换过程时,终端装置可以执行使用随机接入前导的切换过程([0213])。此外,在所述切换过程(图4流程)失败时,终端装置也可能转移到使用随机接入前导(PRACH)的切换过程([0231])。随机接入过程的第一步就是发送第一随机接入消息(即随机接入前导/PRACH)。虽然对比文件没有明确说明该第一随机接入消息的发射功率是否基于前述确定的“上行链路发射功率”,但本领域技术人员知晓,任何上行传输都需要一个发射功率。结合对比文件中关于功率控制调整值“移交”的描述([0223]),可以合理推断,当从基于SRS测量的快速切换流程转入随机接入流程时,终端装置可以基于之前确定的或配置的功率参数(如初始功率或功率调整值)来设定第一随机接入消息的发射功率。这与目标专利中为解决“快速切换”问题而可能以优化后的功率发起随机接入的作用是类似的。因此,该技术特征被对比文件直接公开。
**技术特征J:以第二上行链路发射功率向所述第二基站发送所述随机接入过程的第二随机接入消息,所述第二随机接入消息包括所述第一随机接入消息的重传,其中,所述第二上行链路发射功率高于所述上行链路发射功率。**<br>**公开性判断:隐含公开**[0213] "The terminal apparatus, in a case that the terminal apparatus does not receive a response from the target base station apparatus for a prescribed duration, may retransmit the PUSCH including the RRC connection reconfiguration complete message." <br>[0225] "The terminal apparatus, in a case of transmitting the PUSCH including the RRC connection reconfiguration complete message to the target base station apparatus, and assuming that an ACK/NACK for the PUSCH cannot be detected in a prescribed duration, may ramp up the transmit power of the PUSCH and retransmit the PUSCH."对比文件描述了在发送包含RRC连接重配置完成消息的PUSCH(可视为一种切换完成消息或随机接入消息的等效)后,若在规定时间内未收到响应或ACK/NACK,终端装置可以提高(ramp up)该PUSCH的发射功率并进行重传([0213], [0225])。这明确公开了在切换相关消息传输失败时,会以更高的发射功率进行重传的机制。虽然这里重传的是PUSCH,而目标专利中重传的是随机接入消息,但两者都是上行传输,且用于解决切换过程中上行链路覆盖或同步问题的机制本质相同。本领域技术人员可以基于该公开内容,容易地联想到在随机接入过程中,如果第一随机接入消息未收到响应,同样可以采用提高功率进行重传的方法。这与目标专利中为解决“快速切换”问题而在随机接入过程中进行功率爬升重传的作用是相同的。因此,该技术特征被对比文件隐含公开。
**技术特征K:还包括:至少部分地基于测量信号质量来确定测量事件;以及向所述第一基站发送至少部分地基于所述测量事件的测量报告,其中,所述上行链路发射功率电平集合是至少部分地基于所述测量报告的。**<br>**公开性判断:直接公开**[0202] "(Step S 001 ) A source base station apparatus configures parameters necessary for a measurement procedure for a terminal apparatus. That is, the source base station apparatus controls measurement for the terminal apparatus. The parameters necessary for the measurement procedure may include a parameter for Radio Resource Management (RRM) measurement (parameter for a measurement configuration), and may include a list of cells as measurement objects." <br>[0204] "(Step S 002 ) The terminal apparatus reports a measurement result to the source base station apparatus." <br>[0208] "(Step S 007 ) The source base station apparatus determines whether to perform a handover to the target base station apparatus or a cell managed by the target base station apparatus, based on a measurement report and information on the RRM."对比文件公开了源基站为终端装置配置测量过程所需的参数,包括RRM测量参数和测量对象小区列表([0202])。终端装置向源基站报告测量结果([0204])。源基站基于测量报告和RRM信息来决定是否执行切换([0208])。测量报告必然是基于对信号质量(如RSRP, RSRQ)的测量并满足特定测量事件(如门限)而产生的。虽然没有直接说明“上行链路发射功率电平集合基于测量报告”,但对比文件公开了源基站基于测量报告决定切换,并在此过程中配置SRS([0205])。本领域技术人员可以理解,测量报告反映了UE与源基站及邻区的信道状况,基站可以根据此报告来调整和配置后续的SRS传输参数(包括功率相关参数),以更好地评估与目标基站的链路。这与目标专利中为解决“快速切换”问题而基于测量报告来配置上行参考信号功率集合的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征L:其中,所述功率参数包括功率校正值。**<br>**公开性判断:直接公开**[0223] "... the uplink grant included in the HO command may include the TPC command for the PUSCH. The target base station apparatus may adjust the transmit power of the PUSCH including the RRC connection reconfiguration complete message by using the TPC command." <br>[0066] "... calculating, based on a transmit power control command included in the uplink grant, a first power control adjustment value used for transmit power of the SRS ..."对比文件明确公开了HO命令中的上行链路准许可能包含用于PUSCH的TPC命令([0223]),并且基于上行链路准许中的TPC命令可以计算出用于SRS发射功率的功率控制调整值([0066])。TPC命令指示的正是对当前发射功率的“校正”或“调整”(即增加或减少一定量),因此该“功率控制调整值”或“TPC命令”本身就是一种“功率校正值”。这与目标专利中为解决“快速切换”问题而提供功率校正参数以精确控制上行发射功率的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征M:其中,所述指令还包括定时提前值或上行链路准许中的一项或多项。**<br>**公开性判断:直接公开**[0211] "(Step S 011 ) ... The HO command may include various higher layer parameters necessary for RRC connection to the target cell. The higher layer parameters may include ... and a Timing Advance (TA) value measured by the target base station apparatus." <br>[0213] "(Step S 013 ) The terminal apparatus, based on a TA command and an uplink grant included in the HO command, transmits a PUSCH including an RRC connection reconfiguration complete message."对比文件明确公开了HO命令(即指令)包含定时提前(TA)值([0211]),并且终端装置基于HO命令中包含的TA命令和上行链路准许来发送PUSCH([0213])。这直接证明了指令中包含了定时提前值和上行链路准许。这与目标专利中为解决“快速切换”问题而在指令中提供这些参数以辅助UE快速同步和资源调度的作用是相同的。因此,该技术特征被对比文件直接公开。
**技术特征N:其中,所述多个上行链路参考信号包括探测参考信号重复。**<br>**公开性判断:隐含公开**[0066] "... transmitting a Sounding Reference Signal (SRS) ..." <br>[0206] "(Step S 006 ) The terminal apparatus transmits an SRS in a prescribed cell based on a parameter for the SRS configuration."对比文件多次提及并明确公开了上行链路参考信号是探测参考信号(SRS)([0066], [0206])。虽然对比文件没有明确使用“重复”一词,但SRS的配置和发送通常是周期性的或基于事件的,可以理解为在多个时间/资源上重复发送以进行信道探测或测量。本领域技术人员能够直接且毫无疑义地确定,SRS传输可以包含多次发送(即重复)。这与目标专利中为解决“快速切换”问题而发送多个上行参考信号(SRS重复)以进行功率探测的作用是相同的。因此,该技术特征被对比文件隐含公开。
