Description

一种信息传输方法及设备
本申请要求在2013年09月27日提交中国专利局、申请号为201310453058.7、申请名称为“一种信息传输方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种信息传输方法及设备。
背景技术
为了进一步提高无线网络容量，小基站在实际系统中将更加广泛地被应用。在一个小基站形成的小区(称为小小区)中，通常只有少数几个用户接入。因此，不同时间段内，一个小小区的业务流量波动较大。
在小小区负载低时，该小小区在大部分子帧上都不传输业务。然而即使在没有业务数据传输的子帧中，采用LTE(Long Term Evolution，长期演进)/LTE-Advanced(Long Term Evolution-Advanced，长期演进增强)技术的小基站还是需要发送业务数据之外的下行信号，例如DL CRS(Downlink common reference signal，下行公共参考信号)。在大量没有业务数据的子帧上传输这些下行信号，会导致小基站不必要的功耗开销，以及小小区之间干扰的不必要增加，进而降低系统性能。
为了减少小基站的功耗，降低小小区之间的干扰，可以考虑将一些没有业务数据传输的小小区关闭。目前LTE/LTE-Advanced技术已经有机制能够关闭小小区。一个小基站可以自主地决定开启或者关闭本小小区。同时，该小基站需要通知邻区它的关闭行为。当网络侧决定需要重新开启一个关闭的小小区时，例如需要小小区提供更大的无线网络容量时，另一个网络节点(例如一个宏基站)通过小区激活机制，通知该关闭的小小区开启。UE(用户设备)可以通过切换流程或者初始流程接入到该刚开启的小小区中。
出于降低基站功耗，避免小区间干扰的目的，其他类型的接入小区(例如AP(接入点)的小区，宏小区等)也可以实现小区的开启/关闭。
所谓小区的关闭状态，是指基站不能在该小区内传输业务数据。所谓小区的开启状态，是指基站可以在该小区内传输业务数据。
在小区开启状态下，接入该小区的UE需要在每个子帧上监测下行控制信道。但在小区关闭状态下，接入该小区的UE不需要在每个子帧上都监测下行控制信道，以降低UE的功耗。
但小区的开启或关闭是网络侧自主行为，UE无法获知小区何时处于开启状态，何时 处于关闭状态，从而也就无法真正实现降低UE功耗的目的。
发明内容
本申请的目的是提供一种信息传输方法及设备，以解决现有技术中无相应的解决方案的问题。
本申请的目的是通过以下技术方案实现的：
一种信息传输方法，包括：
在小区内发送小区状态指示信息，该小区状态指示信息用于指示小区在该小区状态指示信息发送时刻之后的预定时间段内的开启或关闭状态。
本申请实施例提供的技术方案，接入网设备在其小区内发送小区状态指示信息，那么，在其小区覆盖范围内的UE就可以接收到该小区状态指示信息，据此确定小区的状态，进而可以真正实现降低UE功耗的目的。
其中，小区状态指示信息是周期性发送的。
较佳地，上述预定时间段为该小区状态指示信息的发送周期。
为了使UE能够准确接收到小区状态指示信息，在上述任意接入网设备侧方法实施例中，较佳地，还可以发送高层信令，通过该高层信令通知小区状态指示信息所在的下行子帧。
基于上述任意接入网设备侧方法实施例，较佳地，该方法还可以包括：在该小区内发送用于小区发现的下行信号、用于移动性测量的下行信号。
其中，用于小区发现的下行信号和用于移动性测量的下行信号可以是周期性发送的。发送周期根据实际网络需求确定。
本申请实施例给出了小区动态开启/关闭场景下如何传输信号的解决方案。本申请实施例提供的上述方法既适用于小区关闭状态，也适用于小区开启状态。在小区关闭状态下，为了使UE能够发现并接入该小区，本申请实施例提供的解决方案中会发送用于小区发现的下行信号和用于移动性测量的下行信号。由于周期性发送用于小区发现的下行信号和用于移动性测量的下行信号，而不是在每个下行子帧上都发送，因此真正实现了减少接入网设备(例如基站)的功耗、降低小区间干扰的目的。
其中，用于小区发现的下行信号的发送周期与用于移动性测量的下行信号的发送周期可以相同，也可以不同。用于小区发现的下行信号与用于移动性测量的下行信号可以在相同的下行子帧上传输，也可以在不同的下行子帧上传输。
进一步的，用于小区发现的下行信号、用于移动性测量的下行信号可以是同一个下行 信号，也可以是不同的下行信号。
为了使UE能够以发送周期相同的接收周期在相应的下行子帧上接收用于小区发现的下行信号和用于移动性测量的下行信号，在以上各个实施例的基础上，还可以发送高层信令，通过该高层信令通知用于小区发现的下行信号所在的下行子帧和用于移动性测量的下行信号所在的下行子帧。
当处于关闭状态的小区中已有UE接入时，为了使UE仍然能够对该小区进行无线链路监测，基于上述任意接入设备侧方法实施例，还可以在该小区内发送用于无线链路监测的下行信号(优选的，该用于无线链路监测的下行信号是周期性发送的)。具体的，可以仅在有已接入的UE，但小区处于关闭状态时，周期性发送用于无线链路监测的下行信号；也可以是无论小区状态，以及无论小区是否有接入的UE，均周期性发送用于无线链路监测的下行信号。
相应的，这三个下行信号的发送周期可以全部相同，也可以是其中两个下行信号的发送周期相同，还可以是这三个下行信号的发送周期各不相同。这三个下行信号可以在相同的下行子帧上传输，也可以是其中两个下行信号在相同的下行子帧上传输，还可以是这三个下行信号分别在不同的下行子帧上传输。
进一步的，用于小区发现的下行信号、用于移动性测量的下行信号和用于无线链路监测的下行信号可以是同一个下行信号，也可以是三个不同的下行信号等等。
进一步的，还可以通过高层信令通知用于无线链路监测的下行信号所在的下行子帧。
具体的，可以通过一个高层信令通知小区状态指示信息、用于小区发现的下行信号、用于移动性测量的下行信号和用于无线链路监测的下行信号所在的下行子帧。
本申请实施例中，在上述小区内周期性发送小区状态指示信息的具体实现方式可以是：
在上述用于小区发现的下行信号所在的下行子帧上发送该小区状态指示信息，发送该小区状态指示信息的周期是发送该用于小区发现的下行信号的周期的正整数倍；或者，
在上述用于移动性测量的下行信号所在的下行子帧上发送该小区状态指示信息，发送该小区状态指示信息的周期是发送该用于移动性测量的下行信号的周期的正整数倍；或者，
在上述用于无线链路监测的下行信号所在的下行子帧上发送该小区状态指示信息，发送该小区状态指示信息的周期是发送该用于无线链路监测的下行信号的周期的正整数倍。
为了进一步降低接入网设备的功耗，基于上述任一接入网设备侧方法实施例，较佳地，当上述小区处于关闭状态时，不需要在每个上行子帧上检测上行数据传输请求，而是周期 性在上行子帧上检测上行数据传输请求，以1个上行子帧为单位，检测上行数据传输请求的周期大于1。
进一步的，还可以发送高层信令，通过该高层信令通知检测上行数据传输请求的上行子帧。
该上行子帧可以是协议约定的，也可以是网络侧预先确定的，还可以实现过程中确定的。
一种UE侧的信息传输方法，包括：
从小区接收小区状态指示信息，该小区状态指示信息用于指示小区在该小区状态指示信息发送时刻之后的预定时间段内的开启或关闭状态；
根据该小区状态指示信息确定该小区在上述预定时间段内的状态。
本申请实施例提供的技术方案，UE能够接收小区状态指示信息，从而确定小区的状态，可以真正实现减少功耗的目的。
其中，小区状态指示信息可以是周期性接收的，接收周期与小区状态指示信息的发送周期相同。
较佳地，上述预定时间段为接收该小区状态指示信息的周期。
相应的，UE在小区状态指示信息指示的小区开启状态时间段内的每个下行子帧上对下行控制信道进行监测，以确定是否有下行业务数据传输。在小区状态指示信息指示的小区关闭状态时间段内，UE可以不对任何一个下行子帧上的下行控制信道进行监测，也可以以较大的子帧间隔对下行控制信道进行监测。
基于上述任一UE侧方法实施例，较佳地，该方法还可以包括：从该小区接收用于小区发现的下行信号和用于移动性测量的下行信号。
其中，用于小区发现的下行信号和用于移动性测量的下行信号可以是周期性接收的。
较佳地，用于小区发现的下行信号的接收周期与用于小区发现的下行信号的发送周期相同；用于移动性测量的下行信号的接收周期与用于移动性测量的下行信号的发送周期相同。具体可以在协议中规定相应的周期，也可以由接入网设备与UE预先约定相应的周期，还可以由接入网设备通过高层信令向UE告知相应的周期。
当然，用于小区发现的下行信号的接收周期也可以大于用于小区发现的下行信号的发送周期，是用于小区发现的下行信号的发送周期的整数倍。用于移动性测量的下行信号的接收周期也可以大于用于移动性测量的下行信号的发送周期，是用于移动性测量的下行信号的发送周期的整数倍。
本申请实施例给出了小区动态开启/关闭场景下如何传输信号的解决方案。本申请实施 例提供的上述方法既适用于小区关闭状态，也适用于小区开启状态。在小区关闭状态下，UE仍然能够接收到用于小区发现的下行信号和用于移动性测量的下行信号，从而发现并接入该小区。由于周期性接收用于小区发现的下行信号和用于移动性测量的下行信号，而不是在每个下行子帧上都接收，因此减少了UE的功耗。
本申请实施例中，如果接入网设备在相同的下行子帧上发送用于小区发现的下行信号和用于移动性测量的下行信号，那么，UE就在该相同的下行子帧上接收用于小区发现的下行信号和用于移动性测量的下行信号。如果接入网设备在不同的下行子帧上发送用于小区发现的下行信号和用于移动性测量的下行信号，那么，UE就分别在发送用于小区发现的下行信号的下行子帧上接收用于小区发现的下行信号，在发送用于移动性测量的下行信号的下行子帧上接收用于移动性测量的下行信号。
进一步的，如果用于小区发现的下行信号和用于移动性测量的下行信号是同一个下行信号，那么，UE就接收该下行信号进行小区发现和移动性测量。
在以上各个UE侧方法实施例的基础上，UE还可以根据接收到的高层信令获知用于小区发现的下行信号所在的下行子帧和用于移动性测量的下行信号所在的下行子帧。
当然，UE也可以通过预先约定、协议规定等方式获知用于小区发现的下行信号所在的下行子帧和用于移动性测量的下行信号所在的下行子帧。
如果UE已接入上述小区，基于上述任意UE侧方法实施例，较佳地，还可以从该小区接收用于无线链路监测的下行信号。
具体可以周期性接收用于无线链路监测的下行信号。
其中，用于无线链路监测的下行信号的接收周期与用于无线链路监测的下行信号的发送周期相同。
当然，用于无线链路监测的下行信号的接收周期也可以大于用于无线链路监测的下行信号的发送周期，是用于无线链路监测的下行信号的发送周期的整数倍。
相应的，如果接入网设备在发送用于小区发现的下行信号和/或用于移动性测量的下行信号的下行子帧上发送用于无线链路监测的下行信号，那么，UE就在该下行子帧上接收用于移动性测量的下行信号。

具体实施方式
在对本申请实施例提供的技术方案进行详细描述之前，首先对其中涉及到的一些技术特征进行解释。
小区开启/关闭：如果接入网设备仅对应一个小区，那么，小区开启也可以说是接入网设备开启，小区关闭也可以说是接入网设备关闭。
接入网设备：指现网中的基站，以及其他具备基站功能的网络实体。例如，小基站，相应的小区即小小区。
当小区处于开启时间段(ON duration)内，接入该小区的UE需要在每个子帧上都监测下行控制信道，用于确定是否有业务数据传输。当小区处于关闭时间段(OFF duration)内，接入该小区的UE不需要在每个子帧上都监测下行控制信道，从而能够节省UE的功耗。 为真正实现节省UE功耗的目的，本申请实施例提供的接入网设备侧的信息传输方法，包括：在小区内发送小区状态指示信息，该小区状态指示信息用于指示小区在该小区状态指示信息发送时刻之后的预定时间段内的开启或关闭状态。
本申请实施例提供的技术方案，接入网设备在其小区内发送小区状态指示信息，那么，在其小区覆盖范围内的UE就可以接收到该小区状态指示信息，据此确定小区的状态，进而可以真正实现降低UE功耗的目的。
其中，小区状态指示信息是周期性发送的。
较佳地，上述预定时间段为该小区状态指示信息的发送周期。
例如，在子帧编号为n的下行子帧上传输的小区状态指示信息，可以指示小区在子帧集合{n+k1,n+k1+1,…,n+k2}上的开启/关闭状态。其中k2>k1>0。k1的取值主要考虑到UE接收和处理该小区状态指示信息所需的时延，以及接入网设备和UE准备业务数据传输的时延，一般在几个至几十个ms之内。如果小区状态指示信息的发送周期为T个子帧，较优的，k2–k1＝T，即每个小区状态指示信息用于指示T个子帧上该小区的开启/关闭状态。
为了使UE能够准确接收到小区状态指示信息，在上述任意接入网设备侧方法实施例中，较佳地，还可以发送高层信令，通过该高层信令通知小区状态指示信息所在的下行子帧。
具体的，该高层信令中可以携带小区状态指示信息的发送周期和该信息在每个发送周期内的子帧位置信息。
假设小区状态指示信息在子帧编号为1的下行子帧上传输，发送周期为一个无线帧。那么，高层信令中携带的发送周期可以是子帧个数10，子帧位置信息可以是子帧编号为1的下行子帧在一个无线帧中的子帧偏移量。
基于上述任意接入网设备侧方法实施例，较佳地，该方法还可以包括：在该小区内发送用于小区发现的下行信号(Discovery Signal)；以及，在该小区内发送用于移动性测量的下行信号(RRM Measurement Signal)。
其中，用于小区发现的下行信号和用于移动性测量的下行信号可以是周期性发送的。发送周期根据实际网络需求确定。
本申请实施例中，在用于小区发现的下行信号的一个发送周期内，既可以通过一个下行子帧发送用于小区发现的下行信号，也可以在多个下行子帧上发送该用于小区发现的下行信号。如果在多个下行子帧上发送该用于小区发现的下行信号，这些下行子帧既可以是连续的下行子帧，也可以是不连续的下行子帧。
在用于移动性测量的下行信号的一个发送周期内，既可以通过一个下行子帧发送用于 移动性测量的下行信号，也可以在多个下行子帧上发送该用于移动性测量的下行信号。如果在多个下行子帧上发送该用于移动性测量的下行信号，这些下行子帧既可以是连续的下行子帧，也可以是不连续的下行子帧。
在频分双工(FDD)系统中，所谓连续的下行子帧是指子帧编号相邻的两个下行子帧；在时分双工(TDD)系统中，所谓连续的下行子帧是指，这两个下行子帧之间不存在其他的下行子帧(但可以存在上行子帧)。
本申请实施例给出了小区动态开启/关闭场景下如何传输信号的解决方案。本申请实施例提供的上述方法既适用于小区关闭状态，也适用于小区开启状态。在小区关闭状态下，为了使UE能够发现并接入该小区，本申请实施例提供的解决方案中会发送用于小区发现的下行信号和用于移动性测量的下行信号。由于周期性发送用于小区发现的下行信号和用于移动性测量的下行信号，而不是在每个下行子帧上都发送，因此真正实现了减少接入网设备(例如基站)的功耗、降低小区间干扰的目的。
本申请实施例中，用于小区发现的下行信号的发送周期与用于移动性测量的下行信号的发送周期可以相同，也可以不同。用于小区发现的下行信号与用于移动性测量的下行信号可以在相同的下行子帧上传输，也可以在不同的下行子帧上传输。
进一步的，用于小区发现的下行信号、用于移动性测量的下行信号可以是同一个下行信号，也可以是不同的下行信号。
为了使UE能够以发送周期相同的接收周期在相应的下行子帧上接收用于小区发现的下行信号和用于移动性测量的下行信号，在以上各个实施例的基础上，还可以发送高层信令，通过该高层信令通知用于小区发现的下行信号所在的下行子帧和用于移动性测量的下行信号所在的下行子帧。具体的，该高层信令中可以携带用于小区发现的下行信号的发送周期和该下行信号在每个发送周期内的子帧位置信息；以及用于移动性测量的下行信号的发送周期和该下行信号在每个发送周期内的子帧位置信息。
假设用于小区发现的下行信号与用于移动性测量的下行信号是同一个下行信号，该下行信号在子帧编号为1的下行子帧上传输，发送周期为一个无线帧。那么，高层信令中携带的发送周期可以是子帧个数10，子帧位置信息可以是子帧编号为1的下行子帧在一个无线帧中的子帧偏移量。
当UE接入到一个小区中后，需要经常对该小区进行无线链路监测(Radio Link Monitoring,RLM)。如果UE测得的当前服务小区的无线链路质量不好，那么UE会上报无线链路失败(Radio Link Failure,RLF)。当RLF持续发生一段时间后，UE进入小区重选过程，即UE会尝试接入别的小区。当处于关闭状态的小区中已有UE接入时，为了使UE 能够进行无线链路监测，基于上述任意接入设备侧方法实施例，还可以在该小区内周期性发送用于无线链路监测的下行信号(RLM Measurement Signal)。具体的，可以仅在有已接入的UE，但小区处于关闭状态时，周期性发送用于无线链路监测的下行信号；也可以是无论小区状态，以及无论小区是否有接入的UE，均周期性发送用于无线链路监测的下行信号。
相应的，这三个下行信号的发送周期可以全部相同，也可以是其中两个下行信号的发送周期相同，还可以是这三个下行信号的发送周期各不相同。这三个下行信号可以在相同的下行子帧上传输，也可以是其中两个下行信号在相同的下行子帧上传输，还可以是这三个下行信号分别在不同的下行子帧上传输。
进一步的，用于小区发现的下行信号、用于移动性测量的下行信号和用于无线链路监测的下行信号可以是同一个下行信号，也可以是三个不同的下行信号等等。
如果发送上述高层信令，进一步的，还通过上述高层信令通知用于无线链路监测的下行信号所在的下行子帧。
从节省接入网设备的功耗角度出发，在上述小区内周期性发送小区状态指示信息的具体实现方式可以是：
在上述用于小区发现的下行信号所在的下行子帧上发送该小区状态指示信息，发送该小区状态指示信息的周期是发送该用于小区发现的下行信号的周期的正整数倍；或者，
在上述用于移动性测量的下行信号所在的下行子帧上发送该小区状态指示信息，发送该小区状态指示信息的周期是发送该用于移动性测量的下行信号的周期的正整数倍；或者，
在上述用于无线链路监测的下行信号所在的下行子帧上发送该小区状态指示信息，发送该小区状态指示信息的周期是发送该用于无线链路监测的下行信号的周期的正整数倍。
为了进一步降低接入网设备的功耗，基于上述任一接入网设备侧方法实施例，较佳地，当上述小区处于关闭状态时，不需要在每个上行子帧上检测上行数据传输请求，而是周期性在上行子帧上检测上行数据传输请求，以1个上行子帧为单位，检测上行数据传输请求的周期大于1。
进一步的，还可以发送高层信令，通过该高层信令通知检测上行数据传输请求的上行子帧。
该上行子帧可以是协议约定的，也可以是网络侧预先确定的，还可以实现过程中确定的。
以同一个下行信号实现用于小区发现、移动性测量和无线链路监测的目的、且该下行 信号与小区状态指示信息在同一个下行子帧传输为例，如果既在小区关闭状态下发送该下行信号，也在小区开启状态下发送该下行信号。那么，在小区关闭和小区开启状态下，可以以相同的发送周期、在相同的子帧上发送该下行信号，如图1所示；也可以以不同的周期和/或在不同的子帧上发送该下行信号。
本申请实施例中上述的各个下行信号，可以是LTE定义的同步信号(Synchronization Signal)，包括PSS(Primary Synchronization Signal，主同步信号)和SSS(Secondary Synchronization Signal，辅同步信号)；或者DL CRS(Downlink Common Reference signal，下行公共参考信号)；或者CSI RS(Channel State Information Reference Signal，信道状态信息参考信号)；或者PRS(Positioning Reference Signal，定位参考信号)。
小区由关闭到开启的状态转换可以是由下行业务数据到达或者是由上行业务数据到达触发的。但现有技术中没有在小区动态开启/关闭场景下的信号传输解决方案，因此，无法保证接入网设备及时获知上行数据请求，也就无法实现关闭状态到开启状态的迅速切换。本申请实施例提供的技术方案，处于关闭时间段内的小区发送Discovery signal和RRM measurement signal，可以使得UE能快速的发现小区，对该小区进行RRM测量，并且决定是否需要接入该小区。一旦UE需要接入该小区，该小区可以快速地从关闭状态转换到开启状态(当然，该小区也可以在UE接入时以及接入后仍然处于关闭状态，直到UE有上行业务数据需要发送时再切换到开启状态)。处于关闭时间段内的小区发送RLM measurement signal，可以使得已经接入到该小区的UE在该小区的关闭时间段内仍可以确定该小区的无线链路质量，从而决定是否在该小区上保持连接或者进入小区重选过程。若UE通过无线链路监测决定在该小区保持连接，当该UE有业务数据需要传输时，该小区可以快速地从关闭状态转换到开启状态。
对于处于关闭时间段的小区，若在一个子帧中有下行业务数据到达，可以在该子帧之后最近的一个发送小区状态指示信息的子帧中发送指示小区开启的信息，使得小区和UE能在相应的子帧集合中进行数据传输。对于处于关闭时间段的小区，若在一个子帧中有上行业务数据到达，则UE需要通知所述小区有上行业务数据需要传输(即上行数据传输请求)，使得该小区能从关闭状态转换到开启状态，进行数据传输。在LTE中，UE可以使随机接入过程或者发送上行调度请求指示(scheduling request indicator,SRI)的方式通知小区有上行业务数据需要传输。
本申请实施例提供的UE侧的信息传输方法，如图2所示，具体包括如下操作：
步骤200、从小区接收小区状态指示信息，该小区状态指示信息用于指示小区在该小区状态指示信息发送时刻之后的预定时间段内的开启或关闭状态；
步骤210、根据该小区状态指示信息确定该小区在上述预定时间段内的状态。
本申请实施例提供的技术方案，UE能够接收小区状态指示信息，从而确定小区的状态，可以真正实现减少功耗的目的。
其中，小区状态指示信息可以是周期性接收的，接收周期与小区状态指示信息的发送周期相同。
较佳地，上述预定时间段为接收该小区状态指示信息的周期。
相应的，UE在小区状态指示信息指示的小区开启状态时间段内的每个下行子帧上对下行控制信道进行监测，以确定是否有下行业务数据传输。在小区状态指示信息指示的小区关闭状态时间段内，UE可以不对任何一个下行子帧上的下行控制信道进行监测，也可以以较大的子帧间隔对下行控制信道进行监测。
基于上述任一UE侧方法实施例，较佳地，该方法还可以包括：从该小区接收用于小区发现的下行信号和用于移动性测量的下行信号。
其中，用于小区发现的下行信号和用于移动性测量的下行信号可以是周期性接收的。
较佳地，用于小区发现的下行信号的接收周期与用于小区发现的下行信号的发送周期相同；用于移动性测量的下行信号的接收周期与用于移动性测量的下行信号的发送周期相同。具体可以在协议中规定相应的周期，也可以由接入网设备与UE预先约定相应的周期，还可以由接入网设备通过高层信令向UE告知相应的周期。
具体的，如果上述小区是UE当前接入的小区，那么，UE从该小区所属的接入网设备获取上述高层信令。如果上述小区不是UE当前接入的小区，那么，UE从其当前接入的小区所属的接入网设备获取上述高层信令。
当然，用于小区发现的下行信号的接收周期也可以大于用于小区发现的下行信号的发送周期，是用于小区发现的下行信号的发送周期的整数倍。用于移动性测量的下行信号的接收周期也可以大于用于移动性测量的下行信号的发送周期，是用于移动性测量的下行信号的发送周期的整数倍。
本申请实施例给出了小区动态开启/关闭场景下如何传输信号的解决方案。本申请实施例提供的上述方法既适用于小区关闭状态，也适用于小区开启状态。在小区关闭状态下，UE仍然能够接收到用于小区发现的下行信号和用于移动性测量的下行信号，从而发现并接入该小区。由于周期性接收用于小区发现的下行信号和用于移动性测量的下行信号，而不是在每个下行子帧上都接收，因此减少了UE的功耗。
本申请实施例中，如果接入网设备在相同的下行子帧上发送用于小区发现的下行信号和用于移动性测量的下行信号，那么，UE就在该相同的下行子帧上接收用于小区发现的 下行信号和用于移动性测量的下行信号。如果接入网设备在不同的下行子帧上发送用于小区发现的下行信号和用于移动性测量的下行信号，那么，UE就分别在发送用于小区发现的下行信号的下行子帧上接收用于小区发现的下行信号，在发送用于移动性测量的下行信号的下行子帧上接收用于移动性测量的下行信号。
进一步的，如果用于小区发现的下行信号和用于移动性测量的下行信号是同一个下行信号，那么，UE就接收该下行信号进行小区发现和移动性测量。
在以上各个UE侧方法实施例的基础上，UE还可以根据接收到的高层信令获知用于小区发现的下行信号所在的下行子帧和用于移动性测量的下行信号所在的下行子帧。
当然，UE也可以通过预先约定、协议规定等方式获知用于小区发现的下行信号所在的下行子帧和用于移动性测量的下行信号所在的下行子帧。
如果UE已接入上述小区，基于上述任意UE侧方法实施例，较佳地，还可以从该小区接收用于无线链路监测的下行信号。
具体可以周期性接收用于无线链路监测的下行信号。
其中，用于无线链路监测的下行信号的接收周期与用于无线链路监测的下行信号的发送周期相同。
当然，用于无线链路监测的下行信号的接收周期也可以大于用于无线链路监测的下行信号的发送周期，是用于无线链路监测的下行信号的发送周期的整数倍。
相应的，如果接入网设备在发送用于小区发现的下行信号和/或用于移动性测量的下行信号的下行子帧上发送用于无线链路监测的下行信号，那么，UE就在该下行子帧上接收用于移动性测量的下行信号。
进一步的，如果用于小区发现的下行信号和用于移动性测量的下行信号是同一个下行信号，且该下行信号也是用于无线链路监测的下行信号，那么，UE还使用该下行信号进行无线链路监测。
如果接收上述高层信令，进一步的，还通过上述高层信令获知用于无线链路监测的下行信号所在的下行子帧。
基于上述任一UE侧方法实施例，较佳地该方法还包括：
根据接收到的高层信令获知检测上行数据传输请求的上行子帧，所述上行子帧由检测上行数据传输请求的周期内的部分上行子帧构成；
在所述上行子帧的至少一个上行子帧上发送上行数据传输请求。
基于与方法同样的发明构思，本申请实施例还提供一种接入网设备，该接入网设备包括：
小区状态指示信息发送模块，用于在该小区内发送小区状态指示信息，该小区状态指示信息用于指示小区在所述小区状态指示信息发送时刻之后的预定时间段内的开启或关闭状态。
其中，小区状态指示信息可以是周期性发送的。
本申请实施例提供的技术方案，接入网设备在其小区内发送小区状态指示信息，那么，在其小区覆盖范围内的UE就可以接收到该小区状态指示信息，据此确定小区的状态，进而可以真正实现降低UE功耗的目的。
较佳地，预定时间段为发送所述小区状态指示信息的周期。
较佳地，还包括下行信号发送模块，用于在所述小区内发送用于小区发现的下行信号和用于移动性测量的下行信号。
其中，用于小区发现的下行信号和用于移动性测量的下行信号可以是周期性发送的。
