Description
本申请要求在2015年4月7日提交中国专利局、申请号为201510161174.0、发明名称为“一种传输配置方法及其设备”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。
本发明涉及无线通信领域,尤其涉及一种传输配置方法及其设备。
随着移动数据业务量的不断增长,频谱资源越来越紧张,在有些情况下,仅使用授权频谱资源进行网络部署和业务传输已经不能满足业务量需求,因此业界提出了LTE-U(Unlicensed LTE,LTE非授权频谱,其中,LTE为Long Term Evolution的英文缩写,即长期演进)技术。LTE-U技术可以在非授权频谱资源上部署传输,以提高用户体验和扩展覆盖。
非授权频谱没有规划具体的应用***,可以为多种无线通信***如蓝牙、Wi-Fi等共享,多种***间通过抢占资源的方式使用共享的非授权频谱资源。非授权频段作为辅载波由授权频段的主载波辅助实现。
LTE***支持FDD(Frequency division duplex,频分双工)和TDD(Time division duplex,时分双工)两种双工方式,分别表示为FDD-LTE与TDD-LTE,两种双工模式使用不同的帧结构。
FDD-LTE与TDD-LTE会分别采用不同的授权频段,这样FDD***的基站只会服务于采用FDD***帧结构的终端,TDD***的基站只能服务于采用TDD***帧结构的终端。如此一来,基站无法同时为支持不同帧结构的两类终端服务。然而在非授权频段或者没有特别为FDD***或TDD***划分专用频谱的频段,为这两类终端共存提供了可能。
但是,目前尚未有一个基站同时调度不同类型终端以及为这两类终端进行传输配置的解决方案。

实施例一
参见图1A,为本发明实施例一提供的在网络侧实现的传输配置流程示意图,如图所示,
该流程可包括如下步骤:
步骤101:网络设备确定被调度的终端,所述被调度的终端包括第一类终端和第二类终端,所述第一类终端仅支持部分子帧;
步骤102:所述网络设备向被调度的第一类终端发送信令,所述信令用于指示所述第一类终端不需要监听的子帧或子帧集合。
上述流程中,所述网络设备可以是基站,比如LTE***中的eNB(evolved NodeB,演进节点B),也可以是具有无线接入功能的其他网络设备。
基于图1A所示的流程,图1B示出了本发明实施例一提供的在终端侧实现的传输配置流程示意图,如图所示,该流程可包括如下步骤:
步骤110:第一类终端接收网络设备发送的信令;其中,所述第一类终端为被网络设备调度的终端,被所述网络设备调度的终端包括第一类终端和第二类终端,所述第一类终端仅支持部分子帧。所述网络设备发送所述信令的方法与图1B所示的流程相同。
步骤111:所述终端根据所述信令确定不需要监听的子帧或子帧集合。
进一步地,在步骤111之后,所述第一类终端可根据该信令对该信令所指示的子帧或子帧集合不进行监听,对于其他子帧则进行监听。
所述第一类终端对子帧进行监听时,至少要解码该子帧内的PDCCH或其他用于承载控制信息的信道,如ePDCCH,从而获得该信道上承载的控制信息,比如,所述控制信息可包括传输格式、资源分配、上行调度许可、功率控制以及上行重传信息等信息。
进一步地,所述第一类终端还可以通过子帧监听过程进行CSI(Channel State Information,信道状态信息)测量,所述CSI中可包括CQI(Channel Quality Indicator,信道质量指示)、RI(rank indication,秩指示)、PMI(Precoding Matrix Indicator,预编码矩阵指示)等信息。
进一步地,所述第一类终端还可以通过子帧监听过程进行RRM(Radio Resource Management,无线资源管理)测量,即,进行RSRP(Reference Signal Receiving Power,参考信号接收功率)与RSRQ(Reference Signal Receiving Quality,参考信号接收质量)等信息的测量。
上述图1A和图1B所示的流程中,所述被调度的终端可以包括第一类终端和第二类终端。其中,第一类终端仅支持部分子帧,第二类终端除了支持第一类终端所支持的子帧以外,还支持其他子帧。比如,第一类终端仅支持下行子帧,第二类终端支持上行子帧和下行子帧。所述第一类终端可支持第一类帧结构,所述第二类终端可支持第二类帧结构。比如,所述第一类帧结构的无线帧为FDD无线帧,所述第二类帧结构的无线帧为TDD无线帧。
图2A示例性地示出了一种第一类帧结构。如图所示,一个无线帧中包含10个1ms
子帧,一个子帧包含2个5ms长的slot(时隙)。在一个无线帧中,所有子帧均为上行子帧或者所有子帧均为下行子帧。
图2B示例性地示出了一种第二类帧结构。如图所示,一个无线帧中包含2个5ms长的半帧,一个半帧包含5个1ms长的子帧。一个无线帧所包含的10个子帧中,既包含上行子帧,也包含下行子帧。
上述图1A和图1B所示的流程中,网络设备可采用多种方式发送所述信令。优选地,所述信令可以通过PDCCH(Physical Downlink Control Channel,物理下行控制信道)或ePDCCH(enhanced Physical Downlink Control Channel,增强的物理下行控制信道)发送,进一步地,可利用DCI(Downlink Control Information,下行控制信息)承载该信令,当然也不排除使用其它承载方式发送该信令。
进一步地,网络设备还可以通过信令将所述第一类终端和所述第二类终端被调度到的无线帧的子帧配置信息通知给所述第二类终端,以使所述第二类终端获得该无线帧的上下行配置信息,从而使所述第一类终端根据该子帧配置信息进行上行数据的发送和下行数据的接收。所述第一类终端和所述第二类终端被调度到的无线帧可以是LTE-TDD的无线帧,当然也可以不局限于LTE-TDD的无线帧结构。
上述流程中,优选地,所述不需要监听的子帧为上行子帧,从而实现第一类终端仅能使用下行子帧进行下行数据传输,而第二类终端还可以进一步使用上行子帧进行上行数据传输。进一步地,第一类终端和第二类终端可以复用相同载波上的下行子帧进行下行数据传输。例如,如果所述第一类终端为支持FDD-LTE帧结构的终端,所述第二类终端为支持TDD-LTE帧结构的终端,且这两类终端被调度到的无线帧中既包含上行子帧又包含下行子帧,则基站可将该无线帧中的上行子帧的帧号等能够标识子帧的信息通过信令发送给支持FDD-LTE帧结构的终端,使该类终端不需要监听这些上行子帧。
上述流程中,所述信令所指示的不需要监听的子帧可位于所述信令所在的无线帧中,即,通过该信令向第一类终端指示出当前无线帧中不需要监听的子帧或子帧集合。所述信令所指示的不需要监听的子帧也可位于所述信令所在的无线帧的下一个无线帧中,即,通过该信令向第一类终端指示出当前无线帧的下一个无线帧中不需要监听的子帧或子帧集合。所述信令所指示的不需要监听的子帧也可位于设定的时间窗内,即,通过该信令向第一类终端指示出该时间窗内不需要监听的子帧或子帧集合。该时间窗的长度可根据需要设定。通过设定时间窗的方式指示该时间窗内不需要监听的子帧或子帧集合,可以更加灵活地对终端进行传输配置。
上述流程的步骤102中,网络设备发送所述信令所使用的载波,与所述第一类终端和所述第二类终端被调度到的载波可以相同也可以不同,即,网络设备可以采用跨载波或同载波的方式为第一类终端指示不需要监听的子帧或子帧集合。
优选地,网络设备发送所述信令所使用的载波为主载波,所述第一类终端和所述第二类终端被调度到的载波为辅载波。比如,在为第一类终端和第二类终端分配非授权频段的传输资源的情况下,网络设备可以使用授权频段的主载波调度第一类终端和第二类终端在非授权频段的辅载波上进行数据传输。
上述流程中,网络设备发送所述信令所使用的载波可以是授权频段上的载波,也可以是非授权频段上的载波。如果网络设备发送所述信令所使用的载波为授权频段上的主载波,则该授权频段上的主载波可采用第一类帧结构也可以采用第二类帧结构。
上述流程中,所述第一类终端和所述第二类终端可以被调度到授权频段的载波上,也可被调度到非授权频段的载波上。
进一步地,在第一类终端和第二类终端被调度到的载波为非授权频段上的载波的情况下,网络设备可采用如下方式中的一种或多种方式的组合,向被调度的第一类终端发送信令,以指示所述第一类终端不需要监听的子帧或子帧集合:
方式1:网络设备在第一无线帧中的第一子帧发送所述信令,所述信令用于指示所述第一类终端在非授权频段的载波上的所述第一无线帧中不需要监听的子帧或子帧集合。优选地,所述第一子帧为子帧0,当然也可以是其他子帧。通过该方式,可以使用一个无线帧中的一个子帧来指示该无线帧中不需要被第一类终端监听的子帧或子帧集合。
方式2:网络设备在所述第一无线帧的第二子帧发送所述信令,所述信令用于指示所述第一类终端在非授权频段载波上的第二无线帧中不需要监听的子帧或子帧集合,所述第二无线帧为所述第一无线帧的下一个无线帧。优选地,所述第二字帧为子帧5,当然也可以是其他子帧,通过该方式,可以使用一个无线帧中的一个子帧来指示下一个无线帧中不需要被第一类终端监听的子帧或子帧集合。
为了更清楚地对上述方式1和方式2进行说明,下面结合图3A、图3B、图4A和图4B进行描述。
图3A和图3B示出了网络设备使用授权频段上的载波发送信令,以指示第一类终端不需要监听的子帧集合的例子。该授权频段上的载波可以是主载波。该授权频段载波采用第一类帧结构,比如,一个无线帧中的子帧为下行子帧,非授权频段的载波可以是辅载波,非授权频段载波采用第二类帧结构,且主载波与辅载波维持子帧对齐。第一类终端与第二类终端被调度到同一个非授权频段载波上,即这两类终端共享一个非授权载波,第一类终端在下行子帧接收数据传输。图3A和图3B仅仅举了主载波全是下行子帧的例子,当然不排除主载波采用第二类帧结构的情况。
如图3A所示,授权频段主载波可以在子帧0或其他子帧,通过PDCCH或者ePDCCH跨载波向第一类终端指示非授权频段辅载波在当前无线帧中不需要监听的子帧集合,比如图中所示的子帧2、子帧3和子帧4,这些子帧均为上行子帧。子帧集合的指示可以用bitmap
的方式指示,比如对于具有10个子帧的无线帧,可使用10个比特指示该无线帧中的哪个或哪些子帧不需要监听,其中,一个比特位对于该无线帧中的一个子帧。
如图3B所示,授权频段主载波在子帧5或其他子帧,通过PDCCH或者ePDCCH跨载波向第一类终端指示非授权频段辅载波在下一个无线帧中不需要监听的子帧集合,比如图中所示的下一个无线帧中的子帧2、子帧3和子帧4,这些子帧均为上行子帧。子帧集合的指示可以用bitmap的方式指示。
图4A和图4B示出了网络设备使用非授权频段上的载波发送信令,以指示第一类终端不需要监听的子帧集合的例子。其中,非授权频段辅载波采用第二类帧结构。第一类终端与第二类终端被调度到同一个非授权频段载波上,即这两类终端共享一个非授权载波,第一类终端在下行子帧接收数据传输。
如图4A所示,非授权频段载波可以在子帧0或其他子帧,通过PDCCH或者ePDCCH,使用本载波向第一类终端指示非授权频段载波在当前无线帧中不需要监听的子帧集合,比如图中所示的子帧2、子帧3和子帧4,这些子帧均为上行子帧。子帧集合的指示可以用bitmap的方式指示。
如图4B所示,非授权频段载波在子帧5或其他子帧,通过PDCCH或者ePDCCH,使用本载波向第一类终端指示非授权频段载波在下一个无线帧中不需要监听的子帧集合,比如图中所示的下一个无线帧中的子帧2、子帧3和子帧4,这些子帧均为上行子帧。子帧集合的指示可以用bitmap的方式指示。
上述流程的步骤101中,网络设备还可以进一步确定被调度的第一类终端和第二类终端所使用的传输资源,即为被调度的终端分配传输资源。为所述第一类终端和所述第二类终端分配的传输资源可以是位于同一频段范围内的传输资源,比如,可为所述第一类终端和所述第二类终端分配相同的载波,即,将所述第一类终端和所述第二类终端调度到相同的载波上。进一步地,该载波可以是授权频段内的载波,也可以是非授权频段内的载波,或者是其他频段内的载波。
如果将所述第一类终端和所述第二类终端调度到相同的载波上,则可采用时分复用的方式、频分复用的方式、空分复用的方式或码分复用的方式,使被调度的所述第一类终端和第二类终端使用该载波进行数据传输。
例如,如果所述第一类终端与所述第二类终端被调度到同一载波的同一无线帧中的下行子帧进行数据传输,则两类终端均可在该下行子帧接收网络设备传输的信号。此时,所述第一类终端与所述第二类终端可以分别占用该载波的不同频段以区分不同类型的终端,即为这两类终端分配不同的频率资源,使第一类终端和第二类终端采用频分复用的方式共享该载波。
可选地,也可以采用空分复用方式,如DL-MIMO(Downlink Multi-Input Multi-Output,
下行-多输入多输出)方式,使所述第一类终端和所述第二类终端共享相同的频域资源与下行子帧。
可选地,还可以将所述第一类终端与所述第二类终端以正交或者非正交扩频码加以区分,使第一类终端和第二类终端使用不同的扩频码,从而实现以码分复用的方式共享相同载波上的下行子帧。进一步地,对于该载波上的上行子帧,则只有第二类终端可以用其进行信号传输。
可选地,网络设备可以在同一载波上,根据实际业务需要,依次分别配置第一类帧结构的无线帧、第二类帧结构的无线帧。第一类帧结构的无线帧可只分配给第一类终端进行数据传输,第二类帧结构的无线帧可以只分配给第二类终端进行数据传输,从而使第一类终端和第二类终端以时分复用的方式共享相同的载波。图5示出了一种通过依次配置第一类帧结构的无线帧、第二类帧结构的无线帧,以实现时分复用的示意图。
通过以上描述可以看出,网络设备可以对不同类型的第一类终端和第二类终端进行调度,其中第一类终端支持部分子帧,并且通过信令通知其中的第一类终端在被调度到的传输资源上需要监听或不需要监听的子帧或子帧集合,从而实现针对不同类型的两类终端进行调度和传输配置。
例如,如果将上述实施例应用于LTE***时,由于LTE***支持FDD和TDD两种双工方式,分别支持不同的帧结构,对于支持FDD帧结构的终端,可通知该类终端在被调度到的传输资源上对上行子帧不需要监听,而对支持TDD帧结构的终端,可将子帧配置信息通知给该类终端,从而使支持FDD帧结构的终端使用下行子帧进行数据传输,使支持TDD帧结构的终端使用上行子帧和下行子帧进行数据传输。特别是在上行子帧比较多的上下行子帧配置中,支持FDD帧结构的终端不监听上行子帧有利于该终端更好地节电。
实施例二
参见图6A,为本发明实施例二提供的在网络侧实现的传输配置流程示意图,如图所示,该流程可包括如下步骤:
步骤601:网络设备确定被调度的终端,所述被调度的终端包括第一类终端和第二类终端,所述第一类终端仅支持部分子帧;
步骤602:所述网络设备向被调度的第一类终端发送信令,所述信令用于指示所述第一类终端需要监听的子帧或子帧集合。
上述流程中,所述网络设备可以是基站,比如LTE***中的eNB,也可以是具有无线接入功能的其他网络设备。
基于图6A所示的流程,图6B示出了本发明实施例二提供的在终端侧实现的传输配置流程示意图,如图所示,该流程可包括如下步骤:
步骤610:第一类终端接收网络设备发送的信令;其中,所述第一类终端为被网络设备调度的终端,被所述网络设备调度的终端包括第一类终端和第二类终端,所述第一类终端仅支持部分子帧。所述网络设备发送所述信令的方法与图6A所示的流程相同。
步骤611:所述终端根据所述信令确定需要监听的子帧或子帧集合。
通过以上流程可以看出,实施例二与实施例一的区别在于:网络设备通过信令指示第一类终端的子帧或子帧集合是该第一类终端需要监听的子帧或子帧集合。相应地,第一类终端可根据该信令确定需要监听的子帧或子帧集合。除此以外,实施例二中涉及到的技术术语或定义与实施例一中的定义相同,实施例二的具体实现过程与实施例一基本相同,因此在此不再详述。
