具体实施方式
下面将结合附图,对本发明实施例中的技术方案进行描述。
图1所示为本发明实施例的一种应用场景的示意性架构图。如图1所示,该应用场景100包括网络设备102,终端设备104以及遮挡物106,该应用场景可以为工厂、港口、仓库、车间等应用场景,该终端设备可以为可移动的终端设备,例如,智能手机、可穿戴的智能手表、港口或工厂等使用的自动牵引车辆(Automated Guided Vehicle,AGV)等,该遮挡物可以是墙壁,车载集装箱、大型置物架、立柱等其他可以造成终端设备接收信号衰落的物体。
如图1所示,在终端设备处于常规覆盖区域时,终端设备可以在常规覆盖模式下接收网络设备102的发送的信号,在终端设备104发生移动时,终端设备104可能移动到遮挡物106的遮挡区域,被遮挡物106遮挡,造成终端设备104接收不到网络设备102的信号,或者造成终端设备104接收信号的质量非常差,此时,需要切换终端设备的覆盖模式,加强终端设备的信号覆盖强度,即使终端设备处于扩展覆盖区域。
基于图1所示的应用场景,本发明实施例提供一种覆盖模式切换的方法,通过终端设备向网络设备发送指示信息,指示网络设备对终端设备的覆盖模式进行切换,从而使得终端设备处于被遮挡物遮挡或者处于信号差的场景时,可以顺利接收到网络设备发送的下行数据,提高用户的体验度。
图2是根据本发明实施例的覆盖模式切换的方法200的示意性流程图,该方法200可以由图1所示的终端设备104执行,例如,可以由智能手机,可穿戴的智能手表,AGV小车等执行。如图2所示的方法200包括:
210,在终端设备确定将当前覆盖模式切换为目标覆盖模式的情况下,该终端设备向网络设备发送第一指示信息,该第一指示信息用于指示网络设备将终端设备的当前覆盖模式切换为目标覆盖模式,所述覆盖模式包括常规覆盖模式和增强覆盖模式;
220,终端设备接收网络设备发送的第二指示信息,该第二指示信息用于指示网络设备已经完成终端设备的当前覆盖模式的切换。
在本发明实施例中,终端设备确定该终端设备是否需要进行覆盖模式切换,在终端设备确定需要进行覆盖模式切换时,该终端设备向网络设备发送第一指示信息,以通知网络设备进行模式切换,使得终端设备可以自主决定是否进行覆盖模式切换,从而使得终端设备可以顺利接收网络设备发送的下行数据信息,提高了用户的体验度。
应理解,该终端设备的当前覆盖模式可以是常规覆盖模式,也可以是增强覆盖模式,该终端设备的目标覆盖模式也可以是常规覆盖模式,也可以是增强覆盖模式。
还应理解,在本发明实施例中,常规覆盖模式一般是指终端设备处于现有小区的覆盖范围内的覆盖模式,一般情况下,在该常规覆盖模式下的下行信道不需要时域重复,该常规覆盖模式下的下行信号可以在一个子帧中解调成功;增强覆盖模式一般是指终端设备处于现有小区的扩展覆盖范围内的覆盖模式,该增强覆盖模式一般可使用提升功率,时域重复或频域扩展等技术以增强下行信号的强度。
可选的,在一些实施例中,在当前覆盖模式与目标覆盖模式不相同时,终端设备向网络设备发送第一指示信息,该第一指示信息用于指示网络设备对终端设备的当前覆盖模式进行切换,在网络设备接收到该第一指示信息之后,网络设备可以根据该第一指示信息,对终端设备的覆盖模式进行切换。
可选的,在一些实施例中,该终端设备的当前覆盖模式也可能与目标覆盖模式相同,在这种情况下,终端设备仍然可以向网络设备发送该第一指示信息,该第一指示信息仍 用于指示网络设备对终端设备的当前覆盖模式进行切换,在网络设备接收到该第一指示信息之后,由于终端设备的当前覆盖模式与目标覆盖模式相同,网络设备可以不对终端设备的覆盖模式进行切换。
应理解,终端设备向网络设备发送第一指示信息方式可以是网络设备配置给终端设备的,使终端设备以周期性的方式向网络设备发送该第一指示信息,所以无论终端设备当前覆盖模式与目标覆盖模式是否相同,终端设备都可以向网络设备发送该第一指示信息。
应理解,在常规覆盖模式下,网络设备向终端设备发送的下行信号为常规下行信号,在增强覆盖模式下,网络设备向终端设备发送的下行信号为增强下行信号。覆盖模式的切换即为网络设备向终端设备发送下行信号方式的转换,该切换过程包括:在终端设备由常规覆盖模式切换到增强覆盖模式时,网络设备向终端设备发送的下行信号由常规下行信号转换为增强下行信号,在终端设备由增强覆盖模式切换到常规覆盖模式时,网络设备向终端设备发送的下行信号由增强下行信号转换为常规下行信号。
在终端设备的当前覆盖模式为常规覆盖模式,当终端设备处于信号较差的环境下,例如,终端设备被大型置物架、立柱、集装箱等物体遮挡时,或终端设备位于小区的边缘等情况下,终端设备此时的目标覆盖模式为增强覆盖模式,即终端设备需要从常规覆盖模式切换到增强覆盖模式,以利于终端设备顺利的接收网络设备发送的下行数据信息,提高用户的体验度。
在终端设备的当前覆盖模式为增强覆盖模式时,在终端设备没有被物体遮挡信号,或者处于小区的中心位置等情况下,为了节省资源,减小网络设备的能耗,可以将终端设备此时的覆盖模式切换为常规覆盖模式,即终端设备需要从增强覆盖模式切换到常规覆盖模式,以利于节省资源,减小网络设备的能耗。
可选的,在一些实施例中,该第一指示信息可以是终端设备在调度请求(Scheduling Request,SR)的预设资源集合中的任意一个资源上发送的SR,该在预设资源集合中的任意一个资源上发送的SR用于指示网络设备将该终端设备的当前覆盖模式切换为目标覆盖模式。
应理解,现有技术中,在终端设备需要向网络设备发送上行数据信息时,终端设备不能直接向网络设备发送上行数据信息,需要首先向网络设备发送上行调度请求SR,通过该SR请求网络设备的上行调度授权,在得到网络设备的上行调度授权之后,终端设备部才可以向网络设备发送上行数据信息。终端设备在与网络设备建立无线资源控制(Radio Resource Control,RRC)时,通过RRC信令向终端设备配置了该SR的资源位置。本发明实施例应用该上行调度请求SR,通过预先配置该SR的一些资源,在该预先配置的SR资源上发送指示信息,以指示网络设备对终端设备的覆盖模式进行切换。
可选的,在一些实施例中,该SR的资源在建立RRC连接时,通过RRC信令进行配置,例如,通过RRC信令中的sr-sPUCCH-ResourceIndex-mf字段进行配置,该字段配置了480种SR的资源,网络设备在向终端设备配置SR的资源时,网络设备会从上述480种SR资源中选取一种,用RRC信令中的sr-sPUCCH-ResourceIndex-mf字段进行配置,该sr-sPUCCH-ResourceIndex-mf字段的取值范围为0~479。
可选的,在一些实施例中,该用于发送SR的子帧的位置还可以通过RRC信令进行配置,例如,可以通过RRC信令中的sr-configIndex(0~157)字段和sr-Trigger0-Window-mf (0~9)字段配置。
可选的,在一些实施例中,上述预设资源集合为上述配置的SR的480种资源中的部分资源的集合,该预设资源集合可以通过RRC信令中的专用字段进行配置,该专用字段为RRC信令中新增加的字段,该专用字段可以是在PhysicalConfigDedicated-MF字段中增加的coverageModeIndication-mf字段。
增加coverageModeIndication-mf字段之后的PhysicalConfigDedicated-MF字段的格式如下所示:
Figure PCTCN2017077375-appb-000001
其中,新增加的coverageModeIndication-mf字段的资源配置如下所示:
Figure PCTCN2017077375-appb-000002
可选的,在一些实施例中,在该新增加的字段配置的SR资源集合上的任意一个资源上发送的SR,可以作为第一指示信息,该第一指示信息用于指示网络设备对终端设备的覆盖模式进行切换。
应理解,在本发明实施例中,在预设资源集合中的任意一个资源上发送的SR其实际的功能还是进行上行调度,本发明实施例中还可以将其作为第一指示信息,用于指示网络设备对终端设备的覆盖模式进行切换,但本发明实施例将其作为第一指示信息并不影响其进行上行调度的功能。
可选的,在一些实施例中,终端设备在预设资源集合中的任意一个资源上发送SR可以使网络设备知道该终端设备当前时刻需要进行覆盖模式切换,网络设备可以根据该终端设备的当前覆盖模式,对该终端设备的当前覆盖模式进行切换。
例如,在该终端设备的当前覆盖模式为常规覆盖模式时,网络设备接收到终端设备在预设资源集合中的任意一个资源上发送的SR,该网络设备可以知道终端设备当前时刻需要进行模式切换,但在该预设资源集合中的任意一个资源上发送的SR,即该第一指示信息没有明确告知网络设备需要将终端设备的当前覆盖模式切换为哪种覆盖模式,所以, 需要网络设备根据该终端设备的当前覆盖模式,确定将终端设备的覆盖模式切换为增强覆盖模式。
可选的,在一些实施例中,该预设资源集合可以包括第一预设资源子集和第二预设资源子集,在该第一预设资源子集中的任意一个资源上发送的SR用于指示网络设备将该终端设备的当前覆盖模式切换为常规覆盖模式,在该第二预设资源子集中的任意一个资源上发送的SR用于指示网络设备将该终端设备的当前覆盖模式切换为增强覆盖模式,即该终端设备可以通过该第一指示信息明确告知网络设备该终端设备当前时刻需要将其覆盖模式切换为哪种覆盖模式。
例如,终端设备在第一预设资源子集中的任意一个资源上发送SR,在网络设备接收到该第一指示信息时,网络设备可以明确的知道该终端设备当前时刻需要将其覆盖模式切换为常规覆盖模式,可以避免网络设备在收到第一指示信息之后,需要根据该终端设备的当前覆盖模式,确定终端设备需要将其覆盖模式切换为哪一种覆盖模式,提高了覆盖模式切换的效率,同时也可以避免在网络设备已经将终端设备的覆盖模式进行了切换,但是向终端设备发送第二指示信息失败,或者终端设备接收第二指示信息失败,导致本次覆盖模式的切换没有完成,在再次进行覆盖模式切换时,网络设备又将终端设备的覆盖模式切换为第一次切换之前的终端设备的覆盖模式,导致覆盖模式的切换错误。
应理解,本发明实施例在进行上行调度请求SR的资源中取出一部分特定的资源,在该取出的一部分特定的资源上发送SR可以使网络设备认为该终端设备当前时刻需要进行覆盖模式的切换。
可选的,在一些实施例中,该第一预设资源子集和第二预设资源子集可以通过RRC信令中的专用字段进行配置,该专用字段为RRC信令中新增加的字段,该专用字段可以是PhysicalConfigDedicated-MF字段中增加的coverageModeIndication-mf字段。
增加coverageModeIndication-mf字段之后的PhysicalConfigDedicated-MF字段的格式如下所示:
Figure PCTCN2017077375-appb-000003
其中,新增加的coverageModeIndication-mf字段的资源配置如下所示:
Figure PCTCN2017077375-appb-000004
Figure PCTCN2017077375-appb-000005
还应理解,本发明实施例又将该取出的一部分特定资源即预设资源集合分为第一预设资源子集和第二预设资源子集,在该第一预设资源子集上发送SR不仅可以使网络设备知道该终端设备当前时刻需要进行覆盖模式切换,还可以使网络设备知道该终端设备需要将当前的覆盖模式切换为常规覆盖模式,在该第二预设资源子集上发送SR不仅可以使网络设备知道该终端设备当前时刻需要进行覆盖模式切换,还可以使网络设备知道该终端设备需要将当前的覆盖模式切换为增强覆盖模式,从而网络设备可以根据在不同资源上接收到的SR直接确定将该终端设备的当前覆盖模式切换为哪一种覆盖模式,不需要网络设备再结合终端设备的当前覆盖模式,确定终端设备需要切换的目标覆盖模式。
可选的,在一些实施例中,在终端设备确定需要进行覆盖模式切换时,终端设备根据其当前的覆盖模式,在不同预设资源集合中的不同资源上向网络设备发送SR,由于终端设备的当前覆盖模式的不同,发送SR的资源不同。
例如,在终端设备确定需要将当前覆盖模式切换为目标覆盖模式时,当终端设备的当前覆盖模式为增强覆盖模式,该终端设备在第一预设资源子集中的任意一个资源上发送SR,用于指示网络设备将该终端设备的覆盖模式切换为增强覆盖模式,当该终端设备的当前覆盖模式为常规覆盖模式时,该终端设备在第二预设资源子集中的任意一个资源上发送SR,用于指示网络设备将该终端设备的覆盖模式切换为常规强覆盖模式。
可选的,在一些实施例中,该第一指示信息还可以是承载在上行链路控制信息(Uplink Control Information,UCI)中的一个字段上的信息。
应理解,在终端设备需要向网络设备发送上行调度请求时,一种方式,终端设备可以向网络设备只发送SR,用于告知网络设备该终端设备需要进行上行数据信息发送,使网络设备给终端设备分配用于发送上行数据信息的资源,另一种方式,终端设备可以向网络设备发送UCI,该UCI中不仅携带了SR,还携带了例如,肯定应答/否定应答(ACK/NACK)信息,信道状态信息(Channel State Information,CSI),信道质量指示(Channel quality indicator,CQI),预编码矩阵指示(Pre-coding Matrix Indicator,PMI)等其他信息,例如,该UCI的格式可以为:ACK/NACK+SR+CSI/CQI/PMI,在本发明实施例中,可以将指示终端设备的覆盖模式切换的指示信息承载在该UCI中,即终端设备向网络设备发送该UCI,该UCI中承载有用于指示网络设备进行终端设备覆盖模式切换的第一指示信息,改变之后的UCI的格式可以为:ACK/NACK+SR+CE+CSI/CQI/PMI,其中,CE即为该第一指示信息。
应理解,该第一指示信息CE所占用的资源的大小可以为1比特位。
可选的,在一些实施例中,在该第一指示信息为承载在UCI中的一个字段上的信息时,该第一指示信息可以包括第一切换指示信息和第二切换指示信息,该第一切换指示信息用于指示网络设备将该终端设备的当前覆盖模式切换为常规覆盖模式,该第二切换指示信息用于指示网络设备将该终端设备的当前覆盖模式切换为增强覆盖模式。
例如,在终端设备确定需要进行覆盖模式切换,且终端设备的当前覆盖模式为增强覆盖模式时,该终端设备向网络设备发送第一切换指示信息,用于指示网络设备将终端 设备的当前覆盖模式切换为常规覆盖模式;在终端设备的当前覆盖模式为常规覆盖模式时,该终端设备向网络设备发送第二切换指示信息,用于指示网络设备将终端设备的当前覆盖模式切换为增强覆盖模式。
可选的,在一些实施例中,上述CE的值为0时,可以用于表示该第一切换指示信息,CE的值为1时,可以用于表示该第二切换指示信息。
应理解,在本发明实施例中,该CE的取值和表示的第一指示信息的种类的对应关系并不限定于此,例如,该CE的值为1,也可以用于表示该第一切换指示信息,该CE的值为0也可以用于表示该第切换指示信息。
可选的,在一些实施例中,终端设备在向网络设备发送第一指示信息之前,该方法200还包括:
205,网络设备向终端设备发送第一配置信息。
可选的,在一些实施例中,该第一配置信息可以包括终端设备的下行参考信号的接收功率(Reference Signal Received Power,RSRP)的第一功率阈值,终端设备用于上报第一指示信息的资源配置信息。例如,用cmn-sPUCCH-ResourceIndex-mf字段配置指示切换到常规覆盖模式的第一指示信息的信号格式,用cme-sPUCCH-ResourceIndex-mf字段配置指示切换到增强覆盖模式的第一指示信息的信号格式,用cm-configIndex(0~157)字段和cm-Trigger0-Window-mf(0~9)字段配置第一指示信息的子帧位置。
可选的,在一些实施例中,该RSRP的第一功率阈值还可以是网络设备通过广播消息为终端设备配置。
进一步的,在一些实施例中,该方法200还包括:
230,终端设备测量该终端设备的下行参考信号接收功率RSRP;
240,将该测量的RSRP与第一功率阈值进行比较,确定该终端设备的目标覆盖模式;
其中,在该RSRP小于该第一功率阈值时,该终端设备的目标覆盖模式为增强覆盖模式,在该RSRP大于或等于该第一功率阈值时,该终端设备的目标覆盖模式为常规覆盖模式。
应理解,由于本发明实施例是终端设备自主确定该终端设备是否需要进行模式切换,所以该终端设备可以通过测量下行参考信号的接收功率,确定该终端设备是否需要进行模式切换,不需要通过网络设备来确定该终端设备是否需要进行覆盖模式切换。
应理解,该第一功率阈值可以通过网络设备配置给终端设备。
250,终端设备判断该终端设备的当前覆盖模式与上述确定的目标覆盖模式是否相同,在当前覆盖模式与上述确定的目标覆盖模式不相同时,该终端设备确定将该终端设备的当前覆盖模式切换为目标覆盖模式。
应理解,在终端设备的当前覆盖模式与目标覆盖模式相同时,虽然该终端设备的当前覆盖模式不需要切换,但是终端设备仍然可以向网络设备发送第一指示信息,只是网络设备接收到该第一指示信息之后,不对该终端设备的当前覆盖模式进行切换。
可选的,在一些实施例中,在终端设备向网络设备发送第一指示信息时,该终端设备同时还可以开启定时器。
可选的,在一些实施例中,终端设备也可以在向网络设备发送第一指示信息之后,开启定时器。
可选的,在一些实施例中,该定时器可以是发送定时器。
具体的,在该定时器有效时间内,若网络设备完成了本次覆盖模式的切换,且终端设备接收到该网络设备发送的第二指示信息,表明本次覆盖模式切换过程完成,终端设备可以向网络设备发送上行数据信息;在定时器有效时间内,网络设备没有进行覆盖模式的切换完成或终端设备没有接收到网络设备发送的第二指示信息,则表明本次切换失败,终端设备将重新向网络设备发送第一指示信息,重新对终端设备的覆盖模式进行切换,与此同时,终端设备重置定时器,重新设置定时器的有效时间,进行下一轮的覆盖模式的切换。
可选的,在一些实施例中,在网络设备接收到终端设备发送的第一指示信息之后,网络设备检测该第一指示信息,在网络设备检测该第一指示信息成功之后,网络设备可以对终端设备的覆盖模式进行切换。
可选的,在一些实施例中,网络设备在检测第一指示信息成功之后,网络设备在当前时刻的下一次(或最近一次)下行调度前或下一次(或最近一次)下行调度时将该终端设备的当前覆盖模式切换为目标覆盖模式。
可选的,在一些实施例中,该网络设备切换终端设备的覆盖模式可以通过网络设备向终端设备发送RRC Reconfig信令对终端设备的覆盖模式进行切换。
应理解,网络设备在检测第一指示信息成功之后,可以在当前时刻的下一次(或最近一次)下行调度中的任意一个下行子帧上切换终端设备的覆盖模式。
可选的,在一些实施例中,在终端设备向网络设备发送第一指示信息之后,该终端设备会将其自身的接收数据信息的方式切换到目标覆盖模式下的接收方式。
应理解,终端设备在不同的覆盖模式下,其接收数据信息的接收方式也不相同,所以,在终端设备向网络设备发送第一指示信息之后,终端设备需要将其自身的接收方式切换为目标覆盖模式下的接收方式。
同样的,在网络设备对终端设备的覆盖模式进行切换之后,网络设备也需要将其自身的发送数据信息的发送方式切换为目标覆盖模式下的发送方式。
应理解,网络设备在不同的覆盖模式下,其发送数据信息的发送方式也不相同,所以,在网络设备对终端设备的覆盖模式进行切换之后,网络设备需要将其自身的发送方式切换为目标覆盖模式下的发送方式。
可选的,在一些实施例中,在网络设备对终端设备的覆盖模式进行切换之后,网络设备向终端设备发送第二指示信息,该第二指示信息用于告知终端设备该网络设备已经完成了覆盖模式的切换。
可选的,在一些实施例中,该第二指示信息可以为RRC信令,该RRC信令中携带了该网络设备当前的模式配置,即该网络设备是否已经将终端设备的覆盖模式切换为目标覆盖模式,以及该网络设备是否在目标覆盖模式下发送的该第二指示信息。
可选的,在一些实施例中,该第二指示信息一般为RRCreconfig消息。
可选的,在一些实施例中,在终端设备将其自身的接收数据信息的接收方式切换为目标覆盖模式下的接收方式的情况下,终端设备需要接收网络设备发送的第二指示信息,该终端设备接收到该第二指示信息之后,终端设备可以根据该第二指示信息中的内容,知道该网络设备是否已经完成了终端设备覆盖模式的切换,以及根据该第二指示信息的内容,知道网络设备是否在目标覆盖模式下发送的该第二指示信息。
可选的,在一些实施例中,终端设备可以通过盲检物理下行控制信道(Physical  Downlink Control Channel,PDCCH)的方式,获取该第二指示信息中的内容,确定该网络设备是否已经完成了终端设备覆盖模式的切换,如果在定时器的有效时间内盲检PDCCH成功,说明网络设备已经完成了终端设备的覆盖模式的切换,且网络设备当前的发送下行数据信息的发送方式为目标覆盖模式下的发送方式,终端设备当前的接收数据信息的方式为目标覆盖模式下的接收方式,即将网络设备的发送方式和终端设备的接收方式进行了对齐。
应理解,造成终端设备盲检PDCCH失败的原因可能有以下几种:一是网络设备检测终端设备发送的第一指示信息失败,因此,网络设备没有对终端设备的覆盖模式进行切换,此时,网络设备不会向终端设备发送第二指示信息,所以导致终端设备盲检PDCCH失败;二是网络设备检测终端设备发送的第一指示信息成功,但是由于其他原因,网络设备没能顺利完成终端设备的覆盖模式的切换,因此,网络设备不会向终端设备发送第二指示信息,导致终端设备盲检PDCCH失败;三是网络设备检测终端设备发送的第一指示信息成功,且网络设备完成了终端设备覆盖模式的切换,但网络设备向终端设备发送第二指示信息时,发送失败,因此终端设备盲检PDCCH失败。上述三种情况都可能造成终端设备盲检PDCCH失败,在终端设备盲检PDCCH失败时,终端设备需要进行下一轮覆盖模式的切换。
应理解,终端设备盲检PDCCH失败的原因可能不止以上三种,本发明实施例仅以以上三种为例进行说明,但本发明实施例并不限定于此。
