Description

定时传输方法和设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种定时传输方法和设备。
背景技术
目前的无线通信系统主要是为人对人(H2H)之间的通信设计的，它对于移动性、时延等方面都有较高的要求。随着智能终端和无线网络通信的发展，很多不需要人参与的机器类型通信(英文：Machine Type Communications，简称：MTC)日益发展，从而出现了设备对设备(英文：Machine-To-Machine，简称：M2M)的无线通信系统，即成为日常生活中不可缺少的部分，这些不需要人参与的网络通信应用于例如遥测、远程信息处理、安全与监控、公共交通、工业应用、远程抄表、家庭应用、销售与支付等。
现有技术中，在M2M无线通信系统中，当MTC设备与网络侧设备需要传输信息时，MTC设备发起随机接入过程，即MTC设备通过物理随机接入信道(英文：Physical Random Access Channel，简称：PRACH)向网络侧设备发送一个或多个长为4096码片的前导码(英文：Preamble)，网络侧设备检测到前导码就会通过捕获指示信道(英文：Acquisition Indication Channel，简称：AICH)向MTC设备发送捕获指示(英文：Acquisition Indication，简称：AI)，MTC设备会监听AICH，只有检测到AI时，MTC设备开始通过PRACH发送的一个长为10ms或20ms的消息(英文：message)部分，该消包括数据消息和控制消息。
然而，M2M无线通信系统中，网络侧设备覆盖范围更广，有些MTC设备离网络侧设备的距离很远，这些MTC设备与网络侧设备相互间传输的前导码和AI可能会接收失败，因此需要提高网络侧设备的覆盖能力。

图5为本发明定时传输方法实施例一的流程图，如图5所示，本实施例的方法可以包括：
S101、UE根据第一PRACH前导码的重复发送方式，向网络侧设备发送N个第一PRACH前导码，所述N为大于或等于2的整数。
本实施例中的UE可以为MTC设备，网络侧设备例如可以为基站。UE可以根据第一PRACH前导码的重复发送方式，向网络侧设备发送N个相同的第一PRACH前导码。其中，N个相同的第一PRACH前导码是承载在PRACH上。
当第一PRACH前导码的重复发送方式为第一重复发送方式时，所述UE根据第一PRACH前导码的重复发送方式，向网络侧设备发送所述N个第一PRACH前导码，包括：所述UE在所述N个连续的接入时隙中向所述网络侧设备发送所述N个第一PRACH前导码，其中，每个所述接入时隙中发送一个所述第一PRACH前导码。具体的，相邻两个所述第一PRACH前导码开始发送的间隔时长为一个接入时隙时长。N个第一PRACH前导码的具体发送方式可以如图6所示，发送N个第一PRACH前导码所需的时间为N个接入时隙。
当所述第一PRACH前导码的重复发送方式为第二重复发送方式时，所述UE根据第一PRACH前导码的重复发送方式，向网络侧设备发送所述N个第一PRACH前导码，包括：所述UE向所述网络侧设备连续发送N个所述第一PRACH前导码。N个第一PRACH前导码的具体发送方式可以如图7所示，发送N个第一PRACH前导码所需时间少于N个接入时隙。
本发明实施例中的第一PRACH前导码的重复发送方式并不以此为限。
S102、所述UE至少根据所述UE发送所述第一PRACH前导码的个数、所述第一PRACH前导码的重复发送方式，确定接收所述网络侧设备发送的与所述第一PRACH前导码对应的AI的时间。
本实施例中，网络侧设备在接收到UE发送的第一PRACH前导码后，会根据该第一PRACH前导码将AI承载在AICH中发送给UE，由于现有技术中UE将同一PRACH前导码只发送一次，网络侧设备接收一个PRACH前导码并处理后即可向UE发送AI；而本发明实施例中UE将同一PRACH前导码发送N次，网络侧设备需要接收N个PRACH前导码并处理后再向UE发送AI，由于网络侧设备接收一个PRACH前导码所需时间与接收N个PRACH前导码所需时间不同，所以使得现有技术中UE接收AI的时间与本发明实施例中UE接收AI的时间不同，因此，UE可以至少根据UE发送第一PRACH前导码的个数N、第一PRACH前导码的重复发送方式，确定UE接收网络侧设备发送与该第一PRACH前导码对应的AI的时间。
S103、所述UE根据接收所述AI的时间，接收所述网络侧设备根据所述AI的重复发送方式发送的M个AI，所述M为大于或等于2的整数。
本实施例中，UE在上述确定的接收AI的时间上，接收网络侧设备根据 AI的重复发送方式发送的M个相同的AI。由于UE向网络侧设备发送多个第一PRACH前导码，可以提高第一PRACH前导码的信噪比，在UE发送多个第一PRACH前导码的基础上，UE确定接收AI的时间，实现AI传输的定时，以保证UE接收AI的时间与网络侧设备发送AI的时间同步，使得UE可以成功接收网络侧设备发送的AI，而且UE接收网络侧设备发送的多个AI，提高了AI的信噪比，进一步保证UE可以成功接收网络侧设备发送的AI，从而使得更远处得UE能够接入网络侧设备，即提高网络侧设备的覆盖能力。在UE接收到AI后，表示UE已经成功接入至网络侧设备，那么UE可以与网络侧设备进行PRACH消息传输。
当所述AI的重复发送方式为第一重复发送方式时，所述UE根据接收所述AI的时间，接收所述网络侧设备根据所述AI的重复发送方式发送的所述M个AI，包括：所述UE根据接收所述AI的时间，接收所述网络侧设备在所述M个连续的接入时隙中发送的所述M个AI，其中，每个所述接入时隙中发送一个所述AI。M个AI的具体发送方式可以如图8所示，发送M个AI所需时间为M个接入时隙。相应地，UE在每一个接入时隙时长中接收一个AI，而且UE开始接收的相邻两个AI的间隔时长为一个接入时隙时长。
当所述AI的重复发送方式为第二重复发送方式时，所述UE根据接收所述AI的时间，接收所述网络侧设备根据所述AI的重复发送方式发送的所述M个AI，包括：所述UE根据接收所述AI的时间，接收所述网络侧设备连续发送的所述M个AI。M个AI的具体发送方式可以如图9所示，发送M个AI所需时间少于M个接入时隙。相应地，UE连续接收M个AI，而且UE开始接收的相邻两个AI的间隔时长为一个所述AI的时间长度。
本发明实施例中的AI的重复发送方式并不以此为限。
本实施例，通过UE根据第一PRACH前导码的重复发送方式，向网络侧设备发送多个第一PRACH前导码，根据所述UE发送所述第一PRACH前导码的个数、所述第一PRACH前导码的重复发送方式，确定接收所述网络侧设备发送的与所述第一PRACH前导码对应的AI的时间，而且根据接收所述AI的时间，接收所述网络侧设备根据所述AI的重复发送方式发送的所述多个AI，从而可以提高PRACH的覆盖能力，也提高了网络侧设备的覆盖能力，也实现了AI传输的定时。
在本发明方法实施例一中，进一步地，所述UE至少根据发送所述UE发送所述第一PRACH前导码的个数、所述第一PRACH前导码的重复发送方式，确定接收所述网络侧设备发送的与所述第一PRACH前导码对应的AI的时间，包括：所述UE根据所述UE发送所述第一PRACH前导码的个数、所述第一PRACH前导码的重复发送方式和AICH传输定时参数指示，确定所述UE开始发送所述N个第一PRACH前导码至所述UE开始接收所述M个AI的第一时间间距；所述UE根据接收所述AI的时间，接收所述网络侧设备根据所述AI的重复发送方式发送M次的AI，包括：所述UE在开始发送所述第一PRACH前导码后，间隔所述第一时间间距开始接收所述网络侧设备根据所述AI的重复发送方式发送的M个AI。
具体地，UE根据第一PRACH前导码的重复发送方式，向网络侧设备发送N个第一PRACH前导码，UE根据UE发送所述第一PRACH前导码的个数、所述第一PRACH前导码的重复发送方式和所述AICH传输定时参数指示，确定所述UE开始发送所述N个第一PRACH前导码中的第一个第一PRACH前导码至所述UE开始接收所述M个AI中第一个AI的第一时间间距，然后UE在开始发送N个第一PRACH前导码中的第一个第一PRACH前导码后，间隔第一时间间距开始接收网络侧设备发送的M个AI中的第一个AI，在提高网络侧设备的覆盖能力的前提下，实现了前导码与AI的定时关系，由于PRACH前导码承载在PRACH中，AI承载在AICH中，也即实现了PRACH与AICH之间的定时关系。
可选的，当所述第一PRACH前导码的重复发送方式为第一重复发送方式、所述AICH传输定时参数指示(AICH_Transmission_Timing)为0时，所述第一时间间距为T1＝(X*N+2560)个码片。其中，X*N个码片表示发送N个第一PRACH前导码所需时间，2560个码片表示网络侧设备处理N个第一PRACH前导码的时间以及传输时延。

可选地，当所述UE未成功接收到所述网络侧设备发送的与所述第一PRACH前导码对应的AI时，所述UE根据所述UE发送所述第一PRACH前导码的个数、所述网络侧设备发送所述AI的个数、所述第一PRACH前导码的重复发送方式、所述AI的重复发送方式和所述AICH传输定时参数指示，确定所述UE开始发送所述N个第一PRACH前导码至所述UE开始发送所述N个第二PRACH前导码的最小时间间距，所述第二PRACH前导码为所述第一PRACH前导码的下一个不同的PRACH前导码；所述UE根据所述最小时间间距、所述第二PRACH前导码的重复发送方式，增加功率向所述网络侧设备发送所述N个第二PRACH前导码，其中，所述UE开始发送所述N个第一PRACH前导码至所述UE开始发送所述N个第二PRACH前导码的时间间距大于或等于所述最小时间间距。
具体地，若UE未成功接收到网络侧设备发送的AI，例如UE未接收到网络侧设备发送的M个AI的中任一个AI，或者，UE接收到了AI但是未正确解码，则UE确定所述UE开始发送所述N个第一PRACH前导码中第一个第一PRACH前导码至所述UE开始发送所述N个第二PRACH前导码中第一个第二PRACH前导码的最小时间间距，然后UE从发送第一个第一PRACH前导码开始，间隔大于或等于上述最小时间间距的时间后，开始发送N个第二PRACH前导码中的第一个第二PRACH前导码。

本发明实施例中的AI的重复发送方式并不以此为限。
本实施例，通过网络侧设备接收所述UE根据第一PRACH前导码的重复发送方式，发送的多个第一PRACH前导码，以及根据AI的重复发送方式，向所述UE发送M个与所述第一PRACH前导码对应的AI，从而可以提高PRACH的覆盖能力，也提高了网络侧设备的覆盖能力。
图11为本发明定时传输方法实施例三的流程图，如图11所示，本实施例的方法可以包括：
S301、UE根据第一PRACH前导码的重复发送方式，发送N个第一PRACH前导码。
S302、网络侧设备接收N个第一PRACH前导码。

S304、所述网络侧设备根据AI的重复发送方式，发送M个AI。
S305、所述UE根据确定的接收AI的时间，接收所述M个AI。
本实施例中，S301-S305的具体实现过程可以参见本发明方法实施例一和二中的相关记载，此处不再赘述。

其中，所述PRACH消息包括PRACH数据消息和PRACH控制消息。可选地，若UE处于CELL_FACH状态，则所述PRACH消息为专用信道(英文：Dedicated Channel，简称：DCH)，所述PRACH数据消息为专用物理数 据信道(英文：Dedicated Physical Data Channel，简称：DPDCH)，所述PRACH控制消息为专用物理控制信道(英文：Dedicated Physical Control Channel，简称：DPCCH)；若UE处于增强的CELL_FACH状态，则所述PRACH消息为增强专用控制信道(英文：Enhanced Dedicated Control Channel，简称：E-DCH)，所述PRACH数据消息为增强专用物理数据信道(英文：Enhanced Dedicated Physical Data Channel，简称：E-DPDCH)，所述PRACH控制消息为DPCCH和增强专用物理控制信道(英文：Enhanced Dedicated Physical Control Channel，简称：E-DPCCH)。
本实施例中，UE在接收网络侧设备发送的AI，解码正确后，会向网络侧设备发送PRACH消息，由于现有技术中网络侧设备将同一AI只发送一次，UE接收一个AI并处理后即可向网络侧设备发送PRACH消息；而本发明实施例中网络侧设备将同一AI发送M次，UE需要接收M个AI并处理后再向网络侧设备发送PRACH消息，由于UE接收一个AI所需时间与接收M个AI所需时间不同，所以使得现有技术中UE发送PRACH消息的时间与本发明实施例中UE发送PRACH消息的时间不同，因此，UE可以根据网络侧设备发送AI的个数M、AI的重复发送方式，确定向网络侧设备发送PRACH消息的时间，然后根据该确定的发送PRACH消息的时间，向网络侧设备发送PRACH消息。
在第一种可行的实现方式中，所述UE至少根据所述网络侧设备发送所述AI的个数、所述AI的重复发送方式，确定向所述网络侧设备发送PRACH消息的时间，包括：所述UE根据所述UE发送所述第一PRACH前导码的个数、所述网络侧设备发送所述AI的个数、所述第一PRACH前导码的重复发送方式、所述AI的重复发送方式和所述AICH传输定时参数指示，确定所述UE开始发送所述N个第一PRACH前导码至所述UE开始发送所述PRACH消息的第二时间间距；所述UE根据发送所述PRACH消息的时间，向所述网络侧设备发送所述PRACH消息，包括：所述UE在开始发送所述N个第一PRACH前导码后，间隔所述第二时间间距开始向所述网络侧设备发送所述PRACH消息。

具体地，UE可以根据AI的发送个数M、AI的重复发送方式，确定所述UE开始接收所述M个AI中第一个AI至所述UE开始发送所述PRACH消息的第三时间间距，然后UE在开始接收所述M个AI中第一个AI后，间隔所述第三时间间距开始向所述网络侧设备发送所述PRACH消息。由于AI是承载在AICH中，PRACH消息承载在DCH或E-DCH中，从而通过上述方式可以实现AICH与DCH或E-DCH之间的定时关系，如图13所示。

在UE接收网络侧设备发送的承载L个第一上行TPC命令的F-DPCH之后，将接收的所述L个第一上行TPC命令进行合并，获得合并后的第一上行TPC命令；所述UE根据所述合并后的第一上行TPC命令，调整发送所述PRACH消息的功率。
可选的，当所述UE接收所述L个第一上行TPC命令中最后一个第一上行TPC命令的时间与第一上行时隙开始的时间之差大于第一预设值，该第一预设值例如为512个码片时，所述UE根据所述合并后的第一上行TPC命令，从所述第一上行时隙开始调整发送所述PRACH消息的功率，如图15所示；当所述UE接收所述L个第一上行TPC命令中最后一个第一上行TPC命令的时间与所述第一上行时隙开始的时间之差小于或等于所述第一预设值时，所述UE根据所述合并后的第一上行TPC命令，从第二上行时隙开始调整发送所述PRACH消息的功率，如图16所示；其中，所述第一上行时隙为所述UE接收所述L个第一上行TPC命令中最后一个第一上行TPC命令之后开始发送上行导频序列所在的上行时隙，所述第二上行时隙为所述第一上行时隙的下一个上行时隙。从而实现UE接收多个第一上行TPC命令与UE调整发送功率的定时关系，即多个第一下行TPC命令生效的定时关系。
