  • CCA clear channel assessment
  • the device Before data transmission, the device first performs idle channel estimation. A common evaluation technique is described as: the transmitter measures the energy on the current channel.

Description

一种消息传输方法及装置 技术领域
本申请涉及物联网通信技术领域，尤其涉及一种消息传输方法及装置。
背景技术
在非授权频谱中，为了减少各发射器之间的干扰，在设备发送前经常需先评估信道的使用情况，空闲信道评估技术(clear channel assessment，CCA)是一种常用的信道评估技术，技术原理可以如图1所示。在数据发送之前，设备首先进行空闲信道评估，常见的一种评估技术描述为：发射器测量当前信道上的能量情况，如果测量得到的能量超过门限，则认为信道被占用，此时不能发送数据；反之，如果测量得到的能量低于门限，则认为信道空闲，此时可以发送数据。这样，设备之间就实现了时分复用对信道进行抢占，避免因同时发送数据而产生的相互干扰。
非授权频谱增强的机器类型连接业务(enhanced machine type communication on unlicensed spectrum，eMTC-U)是工作在非授权频谱上的一种机器类通信技术。其主要目的是实现长距离、低成本、低功耗的物联网通信。其上行发送采用非自适应跳频，主要工作频点是2.4GHz，也可以扩展到其他非授权频谱上。下行采用跳频或者宽带技术。为了减少同步时间和降低功耗，其主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)和系统消息需要在一个或者若干个固定频点的信道上进行发送。其数据信道在数据发送之前先进行CCA，如果CCA成功则进行数据发送；否则在CCA时间窗内继续进行CCA，直到CCA成功后进行数据发送，如果CCA时间窗内信道检测结果为信道始终被占用，则发射器等到下一个CCA时刻或CCA周期重新进行信道抢占。
基站在与终端(user equipment，UE)通信过程中，需要向终端发送寻呼消息和/或系统信息，对于寻呼消息来说，同一个基站下的每个终端存在各自的寻呼周期，各终端的寻呼周期可能相同，也可能不同；对于每一个系统信息来说，同一个基站下的所有终端对应的系统信息周期相同。由于基站发送数据之前需要进行CCA，如果CCA失败，则存在寻呼消息和/或系统信息不能及时发送的情况。
发明内容
本申请的实施例提供一种消息传输方法及装置，可以在CCA失败的情况下提升消息发送的成功率。

在长期演进(long term evolution，LTE)系统中的寻呼的示意图可以如图3所示，为了减少终端电池消耗，系统定义了寻呼周期，每个终端在寻呼周期内对应各自的寻呼帧和寻呼子帧/时刻，即终端只需在特定的寻呼时刻检测寻呼消息，即终端可以采用非连续接收(discontinues reception，DRX)。寻呼周期也可以称为Paging DRX cycle或DRX cycle。基站在发送数据之前，需要先进行空闲信道评估(clear channel assessment，CCA)，测量当前信道上的能量，当CCA成功时，在寻呼时刻需要向特定UE发送寻呼消息。
DRX的目的为了节省UE的能耗，基站给UE发送DRX配置参数，比如DRX周期等，使得UE能处于激活期和休眠期两个状态。在休眠期，UE停止监听PDCCH消息，关闭射频(radio frequency，RF)收发机，在激活期就正常监听PDCCH，打开RF收发机。
图3中所示的寻呼帧(paging frame，PF)表示寻呼消息应该出现在哪个系统帧上，包含一个或者多个寻呼时刻。PO是一个子帧，表示可能在哪个子帧时刻传输寻呼无线网络临时标识(paging-radio network tempory identity，P-RNTI)加扰的物理下行控制信道(physical downlink control channel，PDCCH)。
在本申请的实施例中，P-RNTI加扰的PDCCH可能需要重复发送多个子帧，每个子帧发送的PDCCH相同，P-RNTI加扰的PDCCH发送的第一个子帧根据由PO决定，即PO对应的是重复发送的多个PDCCH中的第一个子帧；如果PO对应的子帧不是一个有效子帧，比如PO对应的子帧不是一个有效下行子帧，则PO之后的第一个有效下行子帧是P-RNTI加扰的PDCCH的第一个子帧。另外，当第一消息为广播消息时，第一消息在第一时间单元可能通过系统信息无线网络临时标识(System Information-Radio Network Temporary Identifier，SI-RNTI)加扰的PDCCH及其对应的PDSCH多次发送，即第一时间单元对应一个时间窗，第一消息在该时间窗内多次重复发送，重复发送的子帧/时隙在该时间窗内可能是连续的，也可能是离散的，相应的，第一消息对应的一个或多个第二时间单元也对应一个时间窗，时间窗长与第一时间单元对应的时间窗长相同，第一消息在第二时间单元对应的时间窗内时连续发送还是离散发送，与第一单元对应的时间窗内相同。
目前，终端设备在一个DRX周期内只需要监听一个PO位置的寻呼消息，终端设备可以根据下述公式来计算PF和PO的位置。
PF的位置可以由公式(1)给出：
SFN mod T＝(T div N)*(UE_ID mod N)………………………………(1)
其中，SFN为系统帧号，T为寻呼周期，N为寻呼周期内寻呼帧的数目，UE_ID为终端设备的标识号。
PO的位置可以由公式(2)给出：
i_s＝floor(UE_ID/N)mod Ns………………………………(2)
其中，i_s为PO的索引号，UE_ID为终端设备的标识号，N为寻呼周期内寻呼帧的数目，Ns为寻呼帧内寻呼子帧的数目。
通过上述公式可以得到PO的位置，终端设备可以在该PO的位置上接收基站发送的寻呼消息。同理，基站也可以通过上述公司得到每个终端的PO的位置，CCA成功后，在该次CCA对应的信道占用时长内，如果存在PO，则在该PO的位置上向终端设备发送寻呼消息，以使终端设备处于激活期。
目前，在不考虑一次信道占用中有多次上下行切换的前提下，CCA的周期是80ms，也就是说如果基站CCA失败，则会导致接下来的80ms都不会在这个信道发送下行数据，这样就会导致Paging无法下发下去。
为了解决这一问题，本申请的实施例提供了一种消息传输方法，需要说明的是，本申请的实施例中的发送周期可以为寻呼周期或广播周期，第一消息可以为寻呼消息或广播消息，其中广播消息可以包括SIB1、SIB2、……、SIB19等系统消息，广播周期还可以包括SIB1、SIB2、……、SIB19等系统消息的发送周期。第一时间单元为第一消息初始发送的时刻，以寻呼消息为例，其第一时间单元为上述PO的位置。第二时间单元为第一消息扩展发送的时刻，也就是说，在当前发送周期内，为第一消息增加的发送机会。
为了能够清楚描述本申请的实施例提供的一种消息传输方法，下面将以寻呼消息和寻呼周期为例来描述消息传输的流程，广播消息和广播周期也适用于该消息传输的流程，对此不作限定。
如图4所示的一种消息传输方法的流程，下面将通过基站与终端设备交互的方式来描述本申请的实施例提供的消息传输方法。
如图4所示，该流程具体包括：
步骤401，在寻呼周期内，基站确定在寻呼消息发送的第一时间单元。
该寻呼消息发送的第一时间单元为寻呼消息发送的初始位置，也就是上述描述的PO所在的位置，基站确定该寻呼消息发送的第一时间单元可以参考上述计算PO的位置的方式，不再赘述。本申请的实施例中的时间单元可以为一个或多个子帧，也可以为一个或多个时隙。
在本申请的实施例中寻呼消息扩展发送的次数可以是系统高层信令配置的，也可以是基站与终端设备约定的。若该寻呼消息扩展发送的次数为系统高层信令配置的，则基站还需要向终端设备通知该寻呼消息扩展发送的次数，以使终端设备可以确定寻呼消息发送的第二时间单元。
需要说明的是，在本申请的实施例中寻呼消息发送的第一时间单元和寻呼消息发送的第二时间单元都是寻呼消息所对应的PDCCH所在的起始位置，也就是在寻呼消息发送的第一时间单元或寻呼消息发送的第二时间单元的起始时刻。
步骤402，基站在第一时间单元的初始位置之前确定CCA失败时，确定寻呼消息发送的第二时间单元。
基站在得到寻呼周期内寻呼消息发送的第一时间单元时，需要在该寻呼消息发送的第一时间单元的初始位置之前判断CCA是成功还是失败。该CCA可以包括eCCA，CCA是在第一时间单元的初始位置之前，该CCA的结束位置可以是第一时间单元的初始位置，也可以提前于第一时间单元的初始位置。
在确定CCA成功时，基站直接在该寻呼消息发送的第一时间单元上向终端设备发送寻呼消息。在确定CCA失败时，基站需要确定寻呼消息发送的第二时间单元，具体的，基站可以依据寻呼消息扩展发送的次数以及预设的时间间隔，确定出在寻呼消息发送的第一时间单元之后的寻呼消息发送的第二时间单元。也可以说，该寻呼消息发送的第二时间单元为在该寻呼消息发送的第一时间单元之后由该寻呼消息扩展发送的次数和预设的时间间隔确定的时间单元。该预设的时间间隔可以为第一时间单元与第二时间单元之间和/或第二时间单元与第二时间单元之间的时间间隔。比如，寻呼消息扩展发送的次数为1时， 该预设的时间间隔是第一时间单元与第二时间单元之间的时间间隔，寻呼消息扩展发送的次数大于1时，该预设的时间间隔还包括第二时间单元与第二时间单元之间的时间间隔。该预设的时间间隔可以根据非授权频谱增强的机器类型连接业务(enhanced machine type communication on unlicensed spectrum，eMTC-U)数据信道一次占用的时长设置，也可以是基站两次CCA抢占信道的起始时间的差值，也可以是依据经验设置的值，本申请的实施例对此不做限定。可选的，为了避免寻呼消息发送的第二时间单元成为连续的时间窗，该预设的时间间隔需要大于1ms。第二时间单元的起始位置可以为该第二时间单元的第一个子帧或时隙。
如图5所示的结构，80ms的CCA的周期内，前5ms为固定频点的信道，用于传输主同步信号、辅同步信号和系统消息等。剩余75ms中起始的几ms进行CCA，CCA的时间可以小于等于3ms。图5中PO1的位置为寻呼消息发送的第一时间单元，也就是寻呼消息发送的起始位置，PO2和PO3是寻呼消息发送的第二时间单元，寻呼消息扩展发送的次数为2。其中，在PO2和PO3的位置上发送寻呼消息之前也需要进行CCA，寻呼周期为320ms。图5所示的结构中，预设的时间间隔为基站两次CCA抢占信道的起始时间的差值，其也可以是依据经验设置的值，比如可以为10ms、20ms等。
步骤403，基站在寻呼消息发送的第一时间单元之后的一个或多个寻呼消息发送的第二时间单元上向终端设备发送寻呼消息。
基站在确定出寻呼消息发送的第二时间单元之后，就可以在该寻呼消息发送的第一时间单元之后的一个或多个寻呼消息发送的第二时间单元上向终端设备发送寻呼消息。
举例来说，基站在第一个寻呼消息发送的第二时间单元的初始位置之前确定CCA成功时，只需要在该第一个寻呼消息发送的第二时间单元上发送寻呼消息，停止在当前周期内该第一个寻呼消息发送的第二时间单元之后的第二时间单元上发送寻呼消息。若基站确定CCA失败，则需要在第二个寻呼消息发送的第二时间单元的初始位置之前确定CCA是否成功，直到在后续的寻呼消息发送的第二时间单元的初始位置之前确定出CCA成功时，基站才会在CCA成功时的寻呼消息发送的第二时间单元上发送寻呼消息。
若基站在所有的寻呼消息发送的第二时间单元的初始位置之前的CCA都失败了，则基站在寻呼周期内不再发送寻呼消息。
如图5所示的结构，寻呼消息对应的第二时间单元个数为2，基站在PO1的初始位置之前确定CCA失败时，基站在PO2的初始位置之前确定CCA是否成功，若成功，基站在PO2的位置向终端设备发送寻呼消息；若失败，则基站在PO3的位置之前确定CCA是否成功。若成功，基站在PO3的位置向终端设备发送寻呼消息；若失败，则基站在寻呼周期内不再向终端设备发送寻呼消息。也就是说，基站在寻呼周期内，只要有一次在寻呼消息发送的第二时间单元的初始位置之前确定CCA成功，就可以在该CCA成功时的寻呼消息发送的第二时间单元上发送该寻呼消息，后续的寻呼消息发送的第二时间单元上不再发送寻呼消息。
可选的，为了不影响寻呼的终端设备的数量，基站在确定寻呼消息发送的第一时间单元之后的一个或多个寻呼消息发送的第二时间单元为第一设备的寻呼消息发送的第一时间单元时，基站在该一个或多个寻呼消息发送的第二时间单元上向终端设备和该第一设备发送寻呼消息，该第一设备为除该终端设备之外的接入该基站的设备。也就是说，当在寻呼消息发送的第二时间单元上既需要向第一设备发送寻呼消息，也需要向终端设备发送寻 呼消息，若此时资源充足，可以同时向该第一设备和该终端设备发送寻呼消息。
若资源不足时，基站先在该一个或多个寻呼消息发送的第二时间单元上向该第一设备发送第一寻呼消息，并在该一个或多个寻呼消息发送的第二时间单元之后的预设时间段内向终端设备发送寻呼消息。也就是说，由于该终端设备的寻呼消息发送的第二时间单元是其它终端设备的寻呼消息发送的第一时间单元时，基站优先向第一设备发送寻呼消息，然后在该终端设备的寻呼消息发送的第二时间单元之后的预设时间段内再向终端设备发送寻呼消息。该预设时间段的起始时刻为所述第二时间单元的起始位置，该预设时间段长度可以依据经验设置的，比如可以是寻呼消息发送的第二时间单元之后的1ms、2ms等，也可以与第二时间单元的位置相关，假定一次寻呼消息发送需要时间长度为delta，单位为子帧或时隙，寻呼消息在第一个第二时间单元上，该预设时间段为2*delta，在第二个第二时间单元上，该预设时间段为3*delta，依次类推，delta为正整数，单位为子帧或时隙。
如图6所示，PO1的位置是基站确定的向UE1和UE2发送寻呼消息时的寻呼消息发送的第一时间单元，PO2的位置是基站确定的向UE3发送寻呼消息时的寻呼消息发送的第一时间单元，PO3是基站确定的向UE4发送寻呼消息时的寻呼消息发送的第一时间单元，而PO2和PO3的位置还是基站确定的UE1和UE2的寻呼消息发送的第二时间单元，PO3的位置还是基站确定的UE3的寻呼消息发送的第二时间单元。
基站在PO1的初始位置之前确定CCA失败时，需要在PO2的位置上向UE1和UE2发送寻呼消息，而PO2的位置还是基站确定的向UE3发送寻呼消息时的寻呼消息发送的第一时间单元，此时基站在一个子帧内资源充足，则在该PO2的位置上开始向UE3发送寻呼消息的同时向UE1和UE2发送寻呼消息。若基站在一个子帧内资源不够，则基站仍在PO2的位置上向UE3发送寻呼消息，在PO2的位置之后的1ms处向UE1和UE2发送寻呼消息。依次类推，若基站在PO2的初始位置之前确定CCA失败，则基站在PO3的位置上先向UE4发送寻呼消息，然后向UE3发送寻呼消息，最后再向UE1和UE2发送消息。若PO3的位置对应的子帧的资源充足，基站也可以同时向UE1、UE2、UE3和UE4发送寻呼消息，若PO3的位置对应的子帧资源不足，可以优先向UE4发送寻呼消息，或者优先向除了UE4之外的UE3和/或UE2和/或UE1发送寻呼消息，其中以PO3的位置为例，假定一次寻呼发送需要1ms，由于PO3的位置为UE3对应的第一个第二时间单元位置，UE3对应的预设时间段可以为2ms，但PO3的位置为UE1和UE2对应的第二个第二时间单元位置，UE1和UE2对应的预设时间段为3ms。
可选的，若上述第一消息为广播消息时，根据广播消息的广播周期不同，可以将该广播消息划分为第一广播消息和第二广播消息，其中，第一广播消息和第二广播消息对应的广播周期不同。基站在该第一广播消息发送的第一时间单元之后的一个或多个第二时间单元上向终端设备发送第一广播消息时，具体为：基站在确定第一广播消息发送的第一时间单元之后的第一广播消息发送的一个或多个第二时间单元为第二广播消息发送的第一时间单元时，基站在该第一广播消息发送的一个或多个第二时间单元上向终端设备发送第一广播消息和第二广播消息。也就是说，当第一广播消息发送的第二时间单元对应的子帧的资源充足时，可以同时发送该第一广播消息和第二广播消息。
若资源不足时，基站先在该一个或多个第一广播消息发送的第二时间单元上向终端设备发送第二广播消息，并在该一个或多个第一广播消息发送的第二时间单元之后的预设时间段内向终端设备发送该第一广播消息。也就是说，由于该第一广播消息发送的第二时间 单元是第二广播消息发送的第一时间单元，此时，基站需要优先发送第二广播消息，然后在该第一广播消息发送的第二时间单元之后的预设时间段内再向终端设备发送第一广播消息。
可选的，上述预设的时间段的大小还可以与寻呼消息扩展发送的次数相关联，也就是说该预设的时间段可以由寻呼消息扩展发送的次数确定，比如该预设时间段可以小于等于寻呼消息扩展发送的次数，或者假定P-RNTI加扰的PDCCH一次发送需要持续N个时间单元，则该预设时间段可以小于等于寻呼消息扩展发送的次数乘以N，或者假定P-RNTI加扰的PDCCH及其对应的PDSCH一次发送需要持续M个时间单元，则该预设时间段可以小于等于寻呼消息扩展发送的次数乘以M。这样在寻呼消息发送的第二时间单元处可以形成一个时间窗，该时间窗的起始位置可以为所述第二时间单元的起始位置，也可以是所述第二时间单元间隔L个子帧或时隙之后的位置，L为正整数，基站可以在该预设的时间段内连续向终端设备发送寻呼消息。
如图7所示的结构中，寻呼消息扩展发送的次数为2，且预设的时间段为3ms，UE1和UE2在寻呼消息发送的第二时间单元处有3ms的发送时间窗，基站可以在这3ms子帧内的任意一个子帧向UE1和UE2发送寻呼消息。
可选的，基站在向终端设备发送第一消息时，是通过加扰的PDCCH向终端设备发送的，或者是通过加扰的PDCCH及其对应的PDSCH向终端设备发送的，该加扰的PDCCH可以为SI-RNTI加扰的PDCCH或P-RNTI加扰的PDCCH，其中，第一消息为广播消息时，该加扰的PDCCH可以为SI-RNTI加扰的PDCCH，第一消息为寻呼消息时，该加扰的PDCCH可以为P-RNTI加扰的PDCCH。
步骤404，在寻呼周期内，终端设备确定寻呼消息发送的第一时间单元。
该寻呼消息发送的第一时间单元为寻呼消息发送的初始位置，也就是上述描述的PO所在的位置，终端设备确定该寻呼消息发送的第一时间单元可以参考上述计算PO的位置的方式，不再赘述。
步骤405，终端设备在第一时间单元的初始位置之前检测到CCA失败时，确定寻呼消息发送的第二时间单元。
终端设备在确定出寻呼周期内寻呼消息发送的第一时间单元时，需要在该寻呼消息发送的第一时间单元的初始位置之前检测基站CCA是成功还是失败，在检测到基站CCA成功时，终端设备在该寻呼消息发送的第一时间单元上接收基站发送的寻呼消息。在检测到CCA失败时，终端设备需要确定寻呼消息发送的第二时间单元，具体的，终端设备可以依据寻呼消息扩展发送的次数以及预设的时间间隔，确定出在寻呼消息发送的第一时间单元之后的寻呼消息发送的第二时间单元。也可以说，该寻呼消息发送的第二时间单元为在该寻呼消息发送的第一时间单元之后由该寻呼消息扩展发送的次数和预设的时间间隔确定的时间单元。该预设的时间间隔可以为第一时间单元与第二时间单元之间和/或第二时间单元与第二时间单元之间的时间间隔。比如，寻呼消息扩展发送的次数为1时，该预设的时间间隔是第一时间单元与第二时间单元之间的时间间隔，寻呼消息扩展发送的次数大于1时，该预设的时间间隔还包括第二时间单元与第二时间单元之间的时间间隔。该预设的时间间隔可以根据eMTC-U数据信道一次占用的时长设置，也可以是基站两次CCA抢占信道的起始时间的差值，也可以是依据经验设置的值，本申请的实施例对此不做限定。可选的，为了避免寻呼消息发送的第二时间单元成为连续的时间窗，该预设的时间间隔需要大 于1ms。
下面对终端检测CCA成功或失败的过程进行描述：
基站侧是通过能量检测等的方式检测CCA是否成功，如背景技术所述；终端对于第一消息的接收，不是判断终端侧CCA是否成功，而是判断基站侧CCA是否成功。只有基站侧CCA成功时，基站才可能会给终端发送第一消息。终端判断基站侧CCA是否成功可以通过如下方式：
方式一：基站在发送下行数据时，会在数据发送起始位置之前发送特定已知序列，终端侧通过使用本地已知序列与接收的的数据序列做相关运算，如果相关结果超过门限值，则终端可以判断基站CCA成功，也即终端判断基站发送了下行数据，如果相关结果不超过门限值，则终端可以判断基站CCA失败，也即终端判断基站没有发送下行数据。
方式二：终端接收第一消息时，终端根据发送周期检测SI-RNTI和/或P-RNTI加扰的PDCCH，如果存在SI-RNTI和/或P-RNTI加扰的PDCCH，则终端可以判断基站CCA成功，也即终端判断基站发送了下行数据。如果终端根据发送周期，判断下行数据中可能包含SI-RNTI和/或P-RNTI加扰的PDCCH，但终端没有检测到SI-RNTI和/或P-RNTI加扰的PDCCH，终端可以判断基站没有发送第一消息，或者判断基站CCA失败。
本方案不对终端判断基站CCA是否成功的方式进行限定。
步骤406，终端设备在寻呼消息发送的第一时间单元之后的一个或多个所述寻呼消息发送的第二时间单元上接收寻呼消息。
终端设备在确定出寻呼消息发送的第二时间单元之后，就可以在该寻呼消息发送的第一时间单元之后的一个或多个寻呼消息发送的第二时间单元上接收基站发送的寻呼消息。
举例来说，终端设备在第一个寻呼消息发送的第二时间单元的初始位置之前检测到基站CCA成功时，只需要在该第一个寻呼消息发送的第二时间单元上接收寻呼消息，停止在当前周期内该第一个寻呼消息发送的第二时间单元之后的第二时间单元上接收寻呼消息。若终端设备检测到CCA失败，则需要在第二个寻呼消息发送的第二时间单元的初始位置之前检测基站CCA是否成功，直到在当前第二时间单元之后的第二时间单元的初始位置之前检测到CCA成功时，终端设备才会在检测到CCA成功时的寻呼消息发送的第二时间单元上接收寻呼消息。
若终端设备在所有的寻呼消息发送的第二时间单元的初始位置之前检测基站确定CCA都失败了，则终端设备在寻呼周期内不再接收寻呼消息。
如图5所示的结构，终端设备在PO1的初始位置之前检测到CCA失败时，终端设备在PO2的初始位置之前检测CCA是否成功，若成功，则终端设备在PO2的位置接收基站发送的寻呼消息；若失败，则终端设备在PO3的初始位置之前检测CCA是否成功。若成功，终端设备在PO3的位置接收基站发送的寻呼消息；若失败，则终端设备在寻呼周期内不再接收寻呼消息。也就是说，终端设备在寻呼周期内，只要有一次在寻呼消息发送的第二时间单元的初始位置之前检测到基站CCA成功，就可以在该CCA成功时的寻呼消息发送的第二时间单元上接收该寻呼消息，在该CCA成功时的寻呼消息发送的第二时间单元之后的第二时间单元上不再接收寻呼消息。
举例来说，寻呼消息扩展发送的次数为M，即第二时间单元有M个位置，加上第一时间单元，一共可以有M+1个发送位置。
终端首先判断第一时间单元CCA是否成功，如果成功，则终端在该发送周期内的第 二时间单元位置不再接收寻呼消息，如果失败，则终端在第二时间单元判断CCA是否成功。
第二时间单元位置为m1，m2，……mM。
终端首先在m1之前判断CCA是否成功，如果成功，则在m1位置接收寻呼消息，在m2，……mM的位置不再接收寻呼消息。如果终端在m1之前判断基站CCA失败，则终端继续在m2之前判断CCA是否成功，一次类推。
假定终端在m1，m2，……mN-1的位置检测CCA失败，在mN的位置检测CCA成功，则终端在mN的位置接收寻呼消息，在mN+1，……mM的位置不再接收寻呼消息。
其中，N小于等于M。
可选的，为了不影响寻呼的终端设备的数量，基站在确定寻呼消息发送的第一时间单元之后的一个或多个寻呼消息发送的第二时间单元为第一设备的寻呼消息发送的第一时间单元时，基站在该一个或多个寻呼消息发送的第二时间单元上向终端设备和该第一设备发送寻呼消息，该第一设备为除该终端设备之外的接入该基站的设备。也就是说，当在寻呼消息发送的第二时间单元上既需要向第一设备发送寻呼消息，也需要向终端设备发送寻呼消息，若此时资源充足，可以同时向该第一设备和该终端设备发送寻呼消息。这种情况下，终端设备在该寻呼消息发送的第二时间单元上接收基站发送的寻呼消息。
若资源不足时，基站先在该一个或多个寻呼消息发送的第二时间单元上向该第一设备发送第一寻呼消息，并在该一个或多个寻呼消息发送的第二时间单元之后的预设时间段内向终端设备发送寻呼消息。也就是说，由于该终端设备的寻呼消息发送的第二时间单元是其它终端设备的寻呼消息发送的第一时间单元时，基站优先向第一设备发送寻呼消息，然后在该终端设备的寻呼消息发送的第二时间单元之后的预设时间段内再向终端设备发送寻呼消息。这种情况下，终端设备在该寻呼消息发送的第二时间单元之后的预设时间段内接收基站发送的寻呼消息。该预设时间段的起始时刻为所述第二时间单元的起始位置，该预设时间段长度可以依据经验设置的，比如可以是寻呼消息发送的第二时间单元之后的1ms、2ms等，也可以与第二时间单元的位置相关，假定一次寻呼消息发送需要时间长度为delta，单位为子帧或时隙，寻呼消息在第一个第二时间单元上，该预设时间段为2*delta，在第二个第二时间单元上，该预设时间段为3*delta，依次类推，delta为正整数，单位为子帧或时隙。
如图6所示，PO1的位置是基站确定的向UE1和UE2发送寻呼消息时的寻呼消息发送的第一时间单元，PO2的位置是基站确定的向UE3发送寻呼消息时的寻呼消息发送的第一时间单元，PO3是基站确定的向UE4发送寻呼消息时的寻呼消息发送的第一时间单元，而PO2和PO3的位置还是基站确定的UE1和UE2的寻呼消息发送的第二时间单元，PO3的位置还是基站确定的UE3的寻呼消息发送的第二时间单元。
基站在PO1的初始位置之前确定CCA失败时，需要在PO2的位置上向UE1和UE2发送寻呼消息，而PO2的位置还是基站确定的向UE3发送寻呼消息时的寻呼消息发送的第一时间单元，此时基站在一个子帧内资源充足，则在该PO2的位置上开始向UE3发送寻呼消息的同时向UE1和UE2发送寻呼消息，UE1和UE2在PO2的初始位置之前检测到基站确定CCA成功后，在该PO2的位置上接收基站发送的寻呼消息，UE3也在该PO2的位置上接收基站发送的寻呼消息。若基站在一个子帧内资源不够，则基站仍在PO2的位置上向UE3发送寻呼消息，在PO2的位置之后的1ms处向UE1和UE2发送寻呼消息。此时， UE1和UE2在PO2的初始位置之前检测到基站CCA成功，则UE1和UE2在PO2的位置之后的1ms处接收基站发送的寻呼消息。依次类推，若终端设备在PO2的初始位置之前检测到基站CCA失败，则终端设备在PO3的位置之后的2ms内接收基站发送的寻呼消息。
可选的，若上述第一消息为广播消息时，根据广播消息的广播周期不同，可以将该广播消息划分为第一广播消息和第二广播消息，其中，第一广播消息和第二广播消息对应的广播周期不同。基站在该第一广播消息发送的第一时间单元之后的一个或多个第二时间单元上向终端设备发送第一广播消息时，具体为：基站在确定第一广播消息发送的第一时间单元之后的第一广播消息发送的一个或多个第二时间单元为第二广播消息发送的第一时间单元时，基站在该第一广播消息发送的一个或多个第二时间单元上向终端设备发送第一广播消息和第二广播消息。也就是说，当第一广播消息发送的第二时间单元对应的子帧的资源充足时，可以同时发送该第一广播消息和第二广播消息。这种情况下，终端设备在该第一广播消息发送的第二时间单元上接收基站发送的第一广播消息。
若资源不足时，基站先在该一个或多个第一广播消息发送的第二时间单元上向终端设备发送第二广播消息，并在该一个或多个第一广播消息发送的第二时间单元之后的预设时间段内向终端设备发送该第一广播消息。也就是说，由于该第一广播消息发送的第二时间单元是第二广播消息发送的第一时间单元，此时，基站需要优先发送第二广播消息，然后在该第一广播消息发送的第二时间单元之后的预设时间段内再向终端设备发送第一广播消息。这种情况下，终端设备在该第一广播消息发送的第二时间单元之后的预设时间段内接收基站发送的该第一广播消息。
可选的，上述预设的时间段的大小还可以与寻呼消息扩展发送的次数相关联，也就是说该预设的时间段可以由寻呼消息扩展发送的次数确定，比如该预设时间段可以小于等于寻呼消息扩展发送的次数，或者假定P-RNTI加扰的PDCCH一次发送需要持续N个时间单元，则该预设时间段可以小于等于寻呼消息扩展发送的次数乘以N，或者假定P-RNTI加扰的PDCCH及其对应的PDSCH一次发送需要持续M个时间单元，则该预设时间段可以小于等于寻呼消息扩展发送的次数乘以M。这样在寻呼消息发送的第二时间单元处可以形成一个时间窗，该时间窗的起始位置可以为所述第二时间单元的起始位置，也可以是所述第二时间单元间隔L个子帧或时隙之后的位置，L为正整数，终端设备可以在该预设的时间段内连续接收基站发送的寻呼消息。
如图7所示的结构中，寻呼消息扩展发送的次数为2，且预设的时间段为3ms，UE1和UE2在寻呼消息发送的第二时间单元处有3ms的发送时间窗，UE1和UE2可以在这3ms内连续接收基站发送的寻呼消息。
可选的，终端设备接收基站发送的第一消息时，可以是通过检测加扰的PDCCH接收寻呼消息，该加扰的PDCCH可以为SI-RNTI加扰的PDCCH或P-RNTI加扰的PDCCH，其中，第一消息为广播消息时，该加扰的PDCCH可以为SI-RNTI加扰的PDCCH，第一消息为寻呼消息时，该加扰的PDCCH可以为P-RNTI加扰的PDCCH。
上述实施例表明，在第一发送周期内，基站确定第一消息发送的第一时间单元，所述发送周期包括下述周期之一：寻呼周期或广播周期，所述第一消息包括下述消息之一：寻呼消息或广播消息，所述时间单元包括下述时间单元之一：一个或多个子帧、一个或多个时隙。在所述第一时间单元的初始位置之前确定CCA失败时，确定所述第一消息发送的第二时间单元，在所述第一消息发送的第一时间单元之后的所述第一消息发送的一个或多 个第二时间单元上向终端设备发送所述第一消息。是在第一时间单元的初始位置之前确定CCA失败时，通过在第一发送周期内的第二时间单元上发送该第一消息，从而可以提升该第一消息发送的成功率。
