Description

报告同失步状态的方法、装置及用户设备 技术领域
本发明涉及无线通信领域，尤其涉及报告同失步状态的方法、装置及用户设备。
背景技术
UMTS(Universal Mobile Telecommunications System，通用移动通信系统)，是国际标准化组织3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)制定的全球3G(3rd Generation)标准之一。在采用UTMS进行通信时中，为保证通信质量，UE(User Equipment，用户设备)需要在通信过程中周期性调整自身的发射功率，即上行内环功率控制。
按照3GPP Release 13(发行版本13)的规定，UE可以采用慢速内环功率控制。在采用上行慢速内环功率控制时，基站可以在每X个时隙通过下行F-DPCH(Fractional dedicated physical channel，碎形专用物理信道)的TPC(Transmission Power Control，传输功率控制)域向UE发送X个相同的上行TPC命令字，并且每个上行TPC命令字的发射功率为预定发射功率的1/X；UE接收并合并该X个上行TPC命令字，然后根据合并后的上行TPC命令字确定抬高或降低上行信道的发射功率。或者，基站也将X个时隙作为一个发送周期，并在每个发送周期内向UE发送一个上行TPC命令字，UE在接收到该上行TPC命令字后，根据该上行TPC命令字确定抬高或降低上行信道的发射功率。其中，预定发射功率可以为现有3GPP协议规定的下行信道发射功率，X的取值可以根据需要设定。采用慢速内环功率控制，可以减少上行TPC命令字的发射数量，或降低上行TPC命令字的发射功率，从而避免功率浪费，节省基站的功耗。
现有技术中，为保证通信质量，除了根据TPC命令字的指示调整上行信道的发射功率之外，UE还需要根据下行F-DPCH TPC域的接收质量来判断UE与基站之间的同失步状态，并将判断结果报告给基站。其中，TPC域的接收质量通常是指TPC域的SIR(Signal to Interference Rate，信干比)，如果SIR高于预定的同步门限，那么UE可以判定UE与基站之间处于同步状态，如果SIR低于预定的失步门限，那么UE 可以判定UE与基站之间处于失步状态。
UE在采用慢速内环功率控制时，如果基站每X个时隙向UE发送X个相同的上行TPC命令字，由于每个上行TPC命令字的实际发射功率调整为预定发射功率的1/X，那么UE在每个时隙测量到的下行信号能量可能会非常低；如果基站每X个时隙才向UE发送一个上行TPC命令字，由于基站连续多个时隙都不向UE发送上行TPC命令字，那么UE不确定什么时候应该接收TPC以及测量接收质量。无论是UE在每个时隙测量到的下行信号能量非常低，还是UE不确定什么时候应该接收TPC以及测量接收质量，都会导致SIR的评估结果不准确。而SIR的评估结果不准确，则会导致同失步状态的判断结果不准确，进而导致UE向基站上报的同失步状态不准确。
由此可以看出，采用上行慢速内环功率控制方式控制UE的发射功率，会导致UE向基站上报的同失步状态不准确。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为本发明报告同失步状态的方法一个实施例的流程示意图；
图2为本发明报告同失步状态的装置一个实施例的结构示意图；
图3为本发明报告同失步状态的方法另一个实施例的流程示意图；
图4为本发明报告同失步状态的装置另一个实施例的结构示意图；
图5为本发明用户设备一个实施例的结构示意图。
具体实施方式
为了使本领域技术人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所述描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参见图1，为本发明报告同失步状态的方法一个实施例的流程示意图。该实 施例可以由UE执行。
步骤101，用户设备将接收到的初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字，所述初始上行传输功率控制命令字是指基站发送的多个相同的上行传输功率控制命令字。所述初始上行传输功率控制命令字可以是指在采用上行慢速内环功率控制时，基站在每个时隙发送的上行传输功率控制命令字。
基站可以以X个时隙为一个发送周期，在同一个发送周期内的每一个时隙向UE发送一个相同的初始上行TPC命令字，从而使得基站可以在一个发送周期内向UE发送X个相同的初始上行TPC命令字。UE接收基站发的初始上行TPC命令字，其中，基站在每个发送周期内发送的初始上行TPC命令字属于同一个上行TPC组，UE需要将该上行TPC组所包含的初始上行TPC命令字合并为一个合并后上行传输TPC命令字。然后根据合并后上行传输TPC命令字的信号质量评估F-DPCH TPC域的接收质量。
其中，基站在发送所述初始上行TPC命令字时，每一个所述初始上行TPC命令字的实际发射功率可以为预定发射功率的1/X，所述预定发射功率是指根据现有无线通信协议确定的发射功率，或者基站根据下行传输功率控制确定的发射功率；X的取值可以预先设定。例如，X的取值可以为5，即以5个时隙为一个发送周期，而每个所述初始上行TPC命令字的实际发射功率可以为预定发射功率的五分之一。
UE可以每个周期合并生成一个合并后上行TPC命令字，或者也可以每隔预定数量的时隙或每隔预定时长生成N个合并后上行TPC命令字。其中，N为正整数，具体的取值可以根据需要进行设定。
可选的，基站在每一个传输周期内发送初始上行TPC命令字可以构成一个上行TPC组，UE可以在接收到一个上行TPC组后，将该上行TPC组所包含的初始上行TPC命令字合并为一个合并后上行TPC命令字。即，UE在接收到X个内容相同的初始上行传输功率控制命令字后，将所述X个初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。
例如，当以5个时隙为一个发送周期时，基站会在一个发送周期的每个时隙内，向UE发送内容相同的初始上行TPC命令字。如果UE在连续5个时隙内接收到的5个初始上行TPC命令字内容相同，那么说明所述5个初始上行TPC命令字属于同一个上行TPC组。UE在接收到所述5个初始上行TPC命令字之后，可以将所述5个所述初始上行TPC命令字合并为一个合并后上行TPC命令字，从而得到1个合并 后上行TPC命令字。如果用初始上行TPC命令字的内容用TPCi表示,那么合并后上行命令字的内容可以用
Figure PCTCN2015090558-appb-000001
表示。
可选的，UE可以将在X个时隙内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字，其中X的取值为正整数。
具体来说，所述UE可以接收基站发送的初始上行传输功率控制命令字；当在X个时隙内接收到的初始上行传输功率控制命令字内容相同时，UE将在所述X个时隙内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。
例如，当以5个时隙为一个发送周期时，每一个上行TPC组中包含5个内容相同的初始上行TPC命令字。UE可以根据初始上行TPC命令字的内容及接收顺序，在每接收到5个内容相同的初始上行TPC命令字后，将所述5个初始上行TPC命令字进行合并为一个合并后TPC命令字。
可选的，UE也可以将在预定时长内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。其中，所述预定时长可以是UE接收到X个初始上行TPC命令字所需的时长。
具体来说，UE可以接收基站发送的初始上行传输功率控制命令字；并且在预定时长内接收到的初始上行传输功率控制命令字内容相同时，将在所述预定时长内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。
例如，如果UE每1毫秒接收到一个初始上行TPC命令字，并且一个上行TPC组包含5个初始上行TPC命令字时，那么所述预定时长就可以为5毫秒。UE可以将每5毫秒内接收到的初始上行TPC命令字合并为一个合并后上行TPC命令字。
在此需要说明的是，将初始上行TPC命令字合并为合并后上行传输TPC的具体方式可以参见现有技术中合并TPC的方式，在此就不再赘述。
步骤102，所述用户设备根据所述合并后上行传输功率控制命令字的信号质量评估出碎形专用物理信道传输功率控制域的接收质量。
在生成合并后上行TPC命令字后，UE可以首先测量合并后上行TPC命令字 的信号质量，然后根据合并后上行TPC命令字的信号质量估计F-DPCH TPC域的接收质量。
UE测量合并后上行TPC命令字信号质量的具体方式可以参见现有技术；UE根据合并后上行TPC命令字信号质量估计F-DPCH TPC域的接收质量具体方式，则可以参见现有技术中UE根据TPC信号质量估计TPC域接收质量的方式。其中，合并后上行TPC命令字的信号质量，可以是指合并后上行TPC命令字的RSCP的接收信号码功率。
例如，当合并后上行TPC命令字由X个初始上行TPC命令字合并而成时，合并后上行TPC命令字的RSCP(Received Signal Code Power，接收信号码功率)为
Figure PCTCN2015090558-appb-000002
其中，Ei表示第i个初始上行TPC命令字的信号质量。F-DPCH TPC域的接收质量则可以用合并后上行TPC命令字的SIR表示，SIR＝(RSCP/ISCP)*SF，上行TPC命令字的RSCP为
Figure PCTCN2015090558-appb-000003
ISCP(Interference Signal Code Power，干扰信号码功率)可以通过测量获知，SF(Spreading Factor，扩频因子)为预设参数。
根据所述接收质量与所述预定的失步门限及失步门限的关系，UE可以选择执行步骤103或步骤104。
步骤103，如果在N个合并后上行传输功率控制命令字内，所述接收质量低于预设的失步门限，则所述用户设备向基站上报第一下行同步原语，所述第一原语用于指示所述用户设备与所述基站之间处于失步状态。
步骤104，如果在N个合并后上行传输功率控制命令字内，所述接收质量高于预设的同步门限，则所述用户设备向基站上报第二下行同步原语，所述第二原语用于指示所述用户设备与所述基站之间处于同步状态。
在此需要说明的是，N的取值为正整数，通常情况下可以根据需要进行设定。例如，N的取值可以为4，当N的取值为4时，UE每合并生成1个合并后上行TPC命令字评估一次F-DPCH TPC域的接收质量，并在测量4个合并后上行TPC的接收质量后上报一次同失步状态。当N的取值为4，而X的取值为5时，意味着UE每接收到20个初始上行TPC命令字向基站上报一次同失步状态，或者说，意味着UE每20个时隙向基站上报一次同失步状态，或者说，意味着UE每间隔接收20个初始上行TPC命令字所需的时长上报一次同失步状态。在本实施例中，用户设备将接收到的初始上行传输功率控制命令字合并为合并后上行传输功率控制命令字；根据所述合 并后上行传输功率控制命令字的信号质量评估出碎形专用物理信道传输功率控制域的接收质量；如果在N个合并后上行传输功率控制命令字内，所述接收质量低于预设的失步门限，则向基站上报第一下行同步原语；如果在N个合并后上行传输功率控制命令字内，所述接收质量高于预设的同步门限，则向基站上报第二下行同步原语。采用本实施例所提供的方法，由于合并后上行TPC命令字的能量远高于初始上行TPC命令字的能量，UE可以根据合并后上行TPC命令字准确测量F-DPCH TPC域的接收质量，从而可以准确向基站上报同失步状态。
参见图2，为本发明报告同失步状态的装置一个实施例的结构示意图。该装置可以设置在UE上，用于执行图1对应实施例所述的报告同失步状态的方法。
如图2所示，所述装置包括：合并单元201，评估单元202，上报单元203。
其中，合并单元201，用于将接收到的初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字，所述初始上行传输功率控制命令字是指基站发送的多个相同的上行传输功率控制命令字。
评估单元202，评估单元202，用于根据所述合并后上行传输功率控制命令字的信号质量评估出碎形专用物理信道传输功率控制域的接收质量。
上报单元203，用于在N个合并后上行传输功率控制命令字内，所述接收质量低于预设的失步门限时，向基站上报第一下行同步原语，所述第一原语用于指示所述用户设备与所述基站之间处于失步状态；或者，用于在N个合并后上行传输功率控制命令字内，所述接收质量高于预设的同步门限时，向基站上报第二下行同步原语，所述第二原语用于指示所述用户设备与所述基站之间处于同步状态。
可选的，所述合并单元201，具体用于在接收到X个内容相同的初始上行传输功率控制命令字后，将所述X个初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字，其中，X的取值为正整数。
可选的，所述合并单元201，具体用于将在X个时隙内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字，其中X的取值为正整数。具体来说，所述装置还可以包括：第一接收单元，用于接收基站发送的初始上行传输功率控制命令字；所述合并单元201，具体用于当在X个时隙内接收到的初始上行传输功率控制命令字内容相同时，将在所述X个时隙内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。
可选的，所述合并单元201，具体用于将在预定时长内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。具体来说，所述装置还包括：第二接收单元，用于接收基站发送的初始上行传输功率控制命令字；所述合并单元201，具体用于当在预定时长内接收到的初始上行传输功率控制命令字内容相同时，将在所述预定时长内接收到的所述初始上行传输功率控制命令字合并为一个合并后上行传输功率控制命令字。
采用本实施例，由于合并后上行TPC命令字的能量远高于初始上行TPC命令字的能量，所述装置可以根据合并后上行TPC命令字准确评估F-DPCH TPC域的接收质量，从而可以准确向基站上报同失步状态。
参见图3，为本发明报告同失步状态的方法另一个实施例的流程示意图。该实施例可以由UE执行。
步骤301，用户设备在接收周期的指定接收位置接收由基站发送的上行传输功率控制命令字，其中，所述发送周期包括至少两个时隙，所述指定接收时隙由无线网络控制器指定。
由于在采用上行慢速内环功率控制时，由于基站可以每X个时隙才向UE发送一次上行TPC命令字，因此基站可以选择在该X个时隙中的任意一个时隙内向UE发送所述上行功率控制命令字。为使UE能够准确的接收基站发送的上行TPC命令字，可以由RNC(Radio Network Controller，无线网络控制器)指示所述UE在指定接收时隙接收所述上行TPC命令字，并指示所述基站在所述指定发送时隙发送所述TPC命令字。其中，所述指定发送/接收时隙可以由RNC通过时隙格式指示信息指示。对于基站来说是发送时隙，对于UE来说是接收时隙。
可选的，所述用户设备接收RNC发送的第一时隙格式指示信息，所述第一时隙格式指示信息用于指示指定发送时隙及指定符号，所述指定发送时隙是指所述基站向所述用户设备发送所述上行传输功率控制命令字所采用的时隙，所述指定符号是指所述上行传输控制命令字在所述指定发送时隙中所占用的符号。在接收到所述第一时隙格式指示信息之后，用户设备再在所述指定发送时隙的所述指定符号接收所述基站发送的所述上行传输功率控制命令字。
所述第一时隙格式指示信息的形式可以为时隙格式表。所述时隙格式表的形式及所包含的内容可以如表1所示。
表1
Figure PCTCN2015090558-appb-000004
其中，NTPC表示每时隙中TPC域的比特数。NOFF1表示每时隙中TPC域距离该时隙开始边界的比特数。NOFF2表示每时隙中TPC域距离该时隙结束边界的比特数，即，NOFF1和NOFF2用于界定TPC域在一个时隙中的位置，X表示每一个发送周期所包含的时隙数量，即基站每X个时隙向UE发送一个上行TPC命令字。在此需要说明的是，第一时隙格式指示信息也可以为其他形式，对此本发明不做限制。
可选的，所述用户设备也可以接收RNC发送的第二时隙格式指示信息，所述第二时隙格式指示信息用于指示指定符号，其中，所述指定符号是指所述上行传输控制命令字在F-DPCH无线帧中所占用的符号；用户设备在接收到所述第二时隙格式指示信息之后，再在F-DPCH无线帧的所述指定符号接收所述基站发送的所述上行传输功率控制命令字。
所述第二时隙格式指示信息所包含的内容及形式可以参见第一时隙格式指示信息，在此就不再赘述。
步骤302，所述用户设备根据所述上行传输功率控制命令字的信号质量评估出碎形专用物理信道传输功率控制域的接收质量。
上行TPC命令字的信号质量可以是指上行TPC命令字的RSCP的接收信号码功率。F-DPCH TPC域的接收质量则可以用UE接收到的上行TPC命令字的SIR表示，SIR＝(RSCP/ISCP)*SF，其中，上行TPC命令字的RSCP(Received Signal Code Power，接收信号码功率)、ISCP(Interference Signal Code Power，干扰信号码功率)可以通过测量获知，SF(Spreading Factor，扩频因子)为预设参数。
UE也可以采用现有技术中的其他方式根据上行TPC命令字的信号质量估计F-DPCH TPC域的接收质量，具体过程在此就不再赘述。
步骤303，如果在N个所述上行传输功率控制命令字内，所述接收质量低于预设的失步门限，则所述用户设备向基站上报第一下行同步原语，所述第一原语用于指示所述用户设备与所述基站之间处于失步状态。
步骤304，如果在N个所述上行传输功率控制命令字内，所述接收质量高于预设的同步门限，则所述用户设备向基站上报第二下行同步原语，所述第二原语用于指示所述用户设备与所述基站之间处于同步状态，其中N的取值为正整数。
在此需要说明的是，根据所述接收质量与所述预定的失步门限及失步门限的关系，UE可以选择执行步骤103或步骤104。
在本实施例中，用户设备在接收周期的指定接收位置接收由基站发送的上行传输功率控制命令字，其中，所述接收周期包括至少两个时隙，所述指定接收时隙由无线网络控制器指定；所述用户设备根据所述上行传输功率控制命令字的信号质量评估出碎形专用物理信道传输功率控制域的接收质量；如果在N个所述上行传输功率控制命令字内，所述接收质量低于预设的失步门限，则所述用户设备向基站上报第一 下行同步原语，所述第一原语用于指示所述用户设备与所述基站之间处于失步状态；如果在N个所述上行传输功率控制命令字内，所述接收质量高于预设的同步门限，则所述用户设备向基站上报第二下行同步原语，所述第二原语用于指示所述用户设备与所述基站之间处于同步状态，其中N的取值为正整数。采用本实施例，UE可以确定基站发送上行TPC命令字的时隙，并根据在该时隙中接收到的TPC命令字判定UE与基站之间的同失步状态，从而可以提高UE上报同失步状态的准确度。
参加图4，为本发明报告同失步状态的装置另一个实施例的结构示意图。
如图4所示，所述装置可以包括：接收单元401、评估单元402及上报单元403。
其中，接收单元401，用于在接收周期的指定接收位置接收由基站发送的上行传输功率控制命令字，其中，所述接收周期包括至少两个时隙，所述指定接收时隙由无线网络控制器指定；评估单元402，用于根据所述上行传输功率控制命令字的信号质量评估出碎形专用物理信道传输功率控制域的接收质量；上报单元403，用于在N个所述上行传输功率控制命令字内，所述接收质量低于预设的失步门限时，向基站上报第一下行同步原语，所述第一原语用于指示所述用户设备与所述基站之间处于失步状态；或者，用于在N个所述上行传输功率控制命令字内，所述接收质量高于预设的同步门限时，向基站上报第二下行同步原语，所述第二原语用于指示所述用户设备与所述基站之间处于同步状态，其中N的取值为正整数。
可选的，所述接收单元401包括：第一指示信息接收子单元，用于接收无线网络控制器发送的第一时隙格式指示信息，所述第一时隙格式指示信息用于指示指定发送时隙及指定符号，其中，所述指定发送时隙是指所述基站向所述用户设备发送所述上行传输功率控制命令字所采用的时隙，所述指定符号是指所述上行传输控制命令字在所述指定发送时隙中所占用的符号；第一命令字接收子单元，用于在所述指定发送时隙的所述指定符号接收所述基站发送的所述上行传输功率控制命令字。

采用本实施例所提供的装置，可以确定基站发送上行TPC命令字的时隙和时 隙中符号位置，并根据在该时隙中接收到的TPC命令字判定UE与基站之间的同失步状态，从而可以提高UE上报同失步状态的准确度。
参见图5，为本发明UE一个实施例的结构示意图。
