  • the present invention relates to the field of communications technologies, and in particular, to a group scheduling feedback method, a base station, and a user equipment.
  • the base station (English: eNodeB, eNB for short) is the same as the user equipment (English: User Equipment, UE for short). Communication and data transmission on one carrier.
  • the UE scheduled by the base station may include its own physical downlink control channel (English: Physical Downlink Control Channel, PDCCH for short) in each subframe, and the PDCCH may be a downlink scheduling assignment (English: DL_Assignment) or an uplink scheduling grant.
  • PDCCH Physical Downlink Control Channel
  • the PDCCH carries a physical downlink shared channel (English: Physical Downlink Shared Channel, PDSCH for short) or a physical uplink shared channel (English: Physical Uplink Shared Channel, PUSCH for short). Scheduling information such as time-frequency resource allocation.
  • the UE After receiving and decoding the PDCCH in the PDCCH search space, the UE receives the downlink data through the PDSCH or sends the uplink data through the PUSCH, and then the UE sends an uplink acknowledgement (English: Acknowledge, ACK for short)/negative response to the downlink data.
  • Negative Acknowledge (NACK) or the base station will feedback the downlink ACK/NACK for the uplink data.
  • the downlink ACK/NACK is also called the Physical Hybrid ARQ Indicator Channel (PHICH). . If the uplink feedback information of the UE or the downlink feedback information of the base station is NACK, the base station or the UE initiates a corresponding retransmission. This process is called Hybrid Automatic Repeat Request (HARQ).
  • HARQ Hybrid Automatic Repeat Request
  • the PDCCH and its scheduled PDSCH or PUSCH, the PDSCH and its corresponding uplink ACK/NACK, and the PUSCH and its corresponding PHICH have a certain timing relationship, that is, the HARQ timing relationship.
  • the DL_Assignment is in the same subframe as its scheduled PDSCH
  • the UL_grant is not in the same subframe as its scheduled PUSCH, the PDSCH and its corresponding uplink ACK/NACK, and the PUSCH and its corresponding PHICH (because the base station or the UE requires a certain processing time, this time interval is generally not less than 4 subframes).
  • the UE in the frequency division duplex (English: Frequency Division Duplex, FDD for short) system, as shown in FIG. 1 , if the UE receives the DL_Assignment and its scheduled PDSCH at time n, the UE will be at time n+4.
  • the uplink ACK/NACK is fed back. If the UE feeds back NACK, the base station selects to retransmit the PDSCH after not less than 4 subframes, because the downlink is an asynchronous HARQ process, that is, the retransmission of the base station does not strictly follow the interval of 4 subframes.
  • FIG. 1 if the UE receives the DL_Assignment and its scheduled PDSCH at time n, the UE will be at time n+4.

Description

一种组调度反馈方法、基站和用户设备 技术领域
本发明涉及通信技术领域,尤其涉及一种组调度反馈方法、基站和用户设备。
背景技术
在长期演进(英文:Long Term Evolution,简称:LTE)Release 8(简称:R8)系统中,基站(英文:eNodeB,简称:eNB)与用户设备(英文:User Equipment,简称:UE)是在同一个载波上进行通信和数据传输的。被基站调度到的UE在每一个子帧内可以包含自己的物理下行控制信道(英文:Physical Downlink Control Channel,简称:PDCCH),PDCCH可以是下行调度分配(英文:DL_Assignment)或者上行调度授权(英文:UL_grant),在这两种情况下PDCCH中分别携带了指示物理下行共享信道(英文:Physical Downlink Shared Channel,简称:PDSCH)或者物理上行共享信道(英文:Physical Uplink Shared Channel,简称:PUSCH)的时频资源分配等调度信息。UE在PDCCH搜索空间中接收并解码PDCCH后,会相应的通过PDSCH接收下行数据或者通过PUSCH发送上行数据,之后UE会对下行数据反馈上行肯定应答(英文:Acknowledge,简称:ACK)/否定应答(英文:Negative Acknowledge,简称:NACK),或者基站会对上行数据反馈下行ACK/NACK,其中,下行ACK/NACK也叫物理混合自动重传指示信道(英文:Physical Hybrid ARQ Indicator Channel,简称:PHICH)。如果UE的上行反馈信息或者基站的下行反馈信息为NACK,则基站或者UE会发起相应的重传,这个过程叫做混合自动重传请求(英文:Hybrid Automatic Repeat Request,简称:HARQ)。
其中,PDCCH与其调度的PDSCH或PUSCH,PDSCH与其对应的上行ACK/NACK,以及PUSCH与其对应的PHICH都有一定的定时关系,即HARQ时序关系。具体地,DL_Assignment与其调度的PDSCH在同一个子帧,而 UL_grant与其调度的PUSCH,PDSCH与其对应的上行ACK/NACK,以及PUSCH与其对应的PHICH都不在同一个子帧(因为基站或者UE都需要一定的处理时间,这个时间间隔一般不小于4个子帧)。具体的,在频分双工(英文:Frequency Division Duplex,简称:FDD)系统中,如图1所示,假设UE在n时刻收到了DL_Assignment和其调度的PDSCH,则UE会在n+4时刻反馈上行ACK/NACK,如果UE反馈的为NACK,那么基站会在不小于4子帧后选择重传PDSCH,因为下行是异步HARQ过程,即基站的重传不严格遵守4个子帧的间隔。同理,如图2所示,假设UE在n时刻收到了UL_grant,那么该UE将在n+4时刻发送对应的PUSCH,相应的,基站会在n+8时刻反馈PHICH给UE,如果基站反馈的为NACK,那么UE会在n+12时刻重传PUSCH,因为上行主要采用同步HARQ过程,即基站和UE都遵循4个子帧的交互间隔。
如图3所示,在现有的单播调度技术中,当基站同时为多个UE调度相同的数据时,为了获知所调度的这多个UE的接收情况,需要为每个UE分配专用的反馈信道资源。由于有的UE可能反馈ACK,有的UE可能反馈NACK,这种反馈信道资源的配置方式可以防止出现因多个UE反馈的信息不同造成相互干扰的情况。但是,这种专用反馈信道资源的配置方式占用的反馈信道资源较多、信令开销较大,尤其不适用于广播和多播的传输场景。

参阅图9所示,本发明实施例中,基站对UE进行组调度的流程如下:
步骤901:基站确定一个分组内的UE。
具体的,所述基站可以根据UE上报的分组信息,来确定所述分组内的UE。或者,所述基站也可以根据核心网设备发送的UE的分组信息,来确定所述分组内的UE。
步骤902:所述基站为所述分组内的UE配置反馈信道资源。
其中,所述基站可以为所述分组内的UE配置相同的反馈信道资源,也可以为所述分组内的UE配置不同的反馈信道资源。例如,所述基站可以将所述分组内的UE再分成不同的反馈组,属于同一个反馈组的UE采用相同的反馈信道资源,属于不同反馈组的UE之间则采用不同的反馈信道资源。
具体的,基站为所述分组内的UE配置的反馈信道资源,可以有但不限于以下两种配置方案:
方案一、
所述基站为所述分组内的每个UE只配置NACK反馈信道资源,用于所述分组内的UE在确定接收的所述数据错误时发送NACK给所述基站。
在方案一这种配置方式下,所述基站还可以通过反馈信道资源的配置信息指示所述分组内的UE在确定接收的所述数据正确时,无需发送ACK给所述基站。
方案二、
所述基站为所述分组内的每个UE配置下述信道资源中的任意组合:
ACK反馈信道资源,用于所述分组内的UE在确定接收的所述数据正确时发送ACK给所述基站;
NACK反馈信道资源,用于所述分组内的UE在确定接收的所述数据错误时发送NACK给所述基站;
参考功率发射信道资源,用于所述分组内的UE在确定接收到所述数据时发送预设的参考信号给所述基站。
基于方案二的这种配置方式,所述基站对所述分组内的UE可以有以下四种配置方法:一、只配置ACK反馈信道资源和NACK反馈信道资源;二、只配置ACK反馈信道资源和参考功率发射信道资源;三、只配置NACK反馈信道资源和参考功率发射信道资源;四、配置ACK反馈信道资源、NACK反馈资源和参考功率发射信道资源。
步骤903:所述基站将所述反馈信道资源的配置信息通知给所述分组内的 UE。
可选地,所述基站可以通过公共信道将反馈信道资源的配置信息发送给所述分组内的UE。
可选的,所述反馈信道资源的配置信息可以指示所述UE不进行反馈。
步骤904:所述基站向所述分组内的UE发送数据。
UE进行下行数据接收,并根据接收的数据信息是否正确以及反馈信道资源的配置方案,确定是否发送反馈信息或者发送何种反馈信息。
例如,在上述方案一的配置方式下,当接收的下行数据信息正确时,UE不反馈任何信息;当接收的下行数据信息错误时,UE使用指定的NACK反馈信道资源反馈NACK。而在上述方案二的配置方式下,当接收的下行数据信息正确且配置了ACK反馈信道资源时,UE使用指定的ACK反馈信道资源反馈ACK;当接收的下行数据信息错误且配置了NACK反馈信道资源时,UE使用指定的NACK反馈信道资源反馈NACK;当接收到了下行数据并且配置了参考功率发射信道资源时,UE使用参考功率发射信道资源发送参考信号给基站。
步骤905:所述基站在所述反馈信道资源上接收所述分组内的UE发送的反馈信息,所述反馈信息用于指示所述数据的接收情况。
具体的,若上述步骤902中采用的是第一种配置方案,那么当所述分组内的UE接收数据错误时,所述基站可以在指定的NACK反馈信道资源上接收到所述分组内的UE发送的NACK。由于所述分组内的UE都采用相同的NACK反馈信道资源,因此所述基站接收到的NACK的功率为所述分组内的所有错误接收到下行数据的UE发送的功率的叠加。
若上述步骤902中采用的是第二种配置方案,由于所述分组内的UE采用的是相同的ACK反馈信道资源、相同的NACK反馈信道资源和相同的参考功率发射信道资源中的任意组合,因此所述基站在ACK反馈信道资源上收到的ACK的功率是所述分组内所有正确接收到下行数据的UE发送的功率的叠加,所述基站在NACK反馈信道资源上收到的NACK的功率是所述分组内所 有错误接收到下行数据的UE发送的功率的叠加,所述基站在参考功率发射信道资源上收到的参考信号的功率则是所有收到下行数据的UE发送的功率的叠加。
进一步地,在步骤904之前,所述基站还可以为所述分组内的UE配置相同的扰码,并将所述扰码通知给所述分组内的UE。
具体的,若上述步骤902中采用的是第一种配置方案,那么所述基站可以为所述分组内的每个UE配置一种扰码,用于对UE反馈的NACK进行加扰;若上述步骤902中采用的是第二种配置方案,那么所述基站可以为所述分组内的每个UE配置一种或多种扰码,用于对UE反馈的ACK、NACK或参考信号进行加扰。
相应的,在步骤905中,所述基站会接收到所述分组内的UE发送的使用所述扰码加扰后的反馈信息。
步骤906:所述基站根据所述反馈信息的功率,确定是否对所述数据进行重传。
与上述步骤902中反馈信道资源的两种配置方案对应的,也有以下两种方法来确定是否需要对所述分组内的UE进行数据重传:
方法一
若上述步骤902中采用的是第一种配置方案,那么所述基站首先确定在所述反馈信道资源上接收到的NACK的功率,然后判断所述NACK的功率是否大于预设的门限值,若是,则对所述数据进行重传,否则,不对所述数据进行重传。
需要说明的是,所述基站根据接收到的NACK的功率确定是否进行数据重传一般可以但不限于有以下几种情况:所述NACK的功率是否大于预设的门限值,或者所述NACK的功率是否满足一个预设条件等。本发明实施例将所述NACK的功率是否大于预设的门限值这种情况为例进行说明,不构成对本发明的限定。
例如,如图10所示,所述基站将小组1内的UE进一步分成2个不同的 反馈组,反馈组1内的每个UE均采用NACK反馈信道资源1,反馈组2内的每个UE均采用NACK反馈信道资源2。当所述基站判断出该分组内任一反馈组(如反馈组1)的UE发送的NACK的叠加功率大于预设的门限值时,便对该分组内所有反馈组的UE进行数据重传。
方法二
若上述步骤902中采用的是第二种配置方案,那么根据所述基站为所述分组内的UE配置的是ACK反馈信道资源、NACK反馈信道资源和参考功率发射信道资源的何种组合,方法二还可以细分为以下三种方式:
方式一:若所述基站为所述分组内的UE配置了ACK反馈信道资源和NACK反馈信道资源,那么所述基站首先分别确定在所述ACK反馈信道资源上接收到的ACK的功率、所述NACK反馈信道资源上接收到的NACK的功率,然后根据ACK的功率和NACK的功率,确定是否对所述数据进行重传。
例如,所述基站可以先确定ACK的功率与NACK的功率的比例值,或者ACK的功率、和ACK的功率与NACK的功率的和值的比例值,或者其他比例值;然后判断所述比例值是否大于预设的门限值时,若是,则对所述数据进行重传,否则,不对所述数据进行重传。
这里提及的ACK的功率与NACK的功率的比例值,即表征了所述分组内发送ACK的UE的数量与发送NACK的UE的数量的比例值。
方式二:若所述基站为所述分组内的UE配置了NACK反馈信道资源和参考功率发射信道资源,那么所述基站首先分别确定在所述NACK反馈信道资源上接收到的NACK的功率、在所述参考功率发射信道资源上接收到的参考信号的功率,然后根据参考信号的功率和NACK的功率,确定是否对所述数据进行重传。
例如,所述基站可以先确定参考信号的功率与NACK的功率的比例值,或者参考信号的功率与NACK的功率的差值、和NACK的功率的比例值,或者其他比例值;然后判断所述比例值是否大于预设的门限值时,若是,则对所述数据进行重传,否则,不对所述数据进行重传。
方式三:若所述基站为所述分组内的UE配置了ACK反馈信道资源和参考功率发射信道资源,那么所述基站首先分别确定在所述ACK反馈信道资源上接收到的ACK的功率、在所述参考功率发射信道资源上接收到的参考信号的功率,然后根据ACK的功率和参考信号的功率,确定是否对所述数据进行重传。
例如,所述基站可以先确定ACK的功率与参考信号的功率的比例值,或者ACK的功率、和参考信号的功率与ACK的功率的差值的比例值,或者其他比例值;然后判断所述比例值是否大于预设的门限值时,若是,则对所述数据进行重传,否则,不对所述数据进行重传。
理论上,所述基站根据ACK的功率、NACK的功率和参考信号的功率中的任意两个功率,即可以计算出所述分组内正确接收下行数据和错误接收下行数据的UE的比例值,从而确定是否需要进行数据重传。
如图11所示,所述基站为所述分组内的UE配置了ACK反馈信道资源、NACK反馈信道资源和参考功率发射信道资源,此时所述基站可以采取上述三种方式中的任一种方式来确定是否需要进行数据重传。在实际应用中,参考信号的功率还可以用于对ACK的功率和NACK的功率的校准。
与图9所示的方法流程对应的,本发明实施例中,UE接受基站的组调度的流程如图12所示:
步骤1201:UE接收基站通知的反馈信道资源的配置信息,根据所述配置信息确定所述基站为所述UE配置的反馈信道资源。
进一步地,所述UE还可能会接收到所述基站通知的扰码。在后续,所述UE使用所述扰码对反馈信息进行加扰,并将加扰后的反馈信息发送给所述基站。
可选地,在UE接收基站通知的反馈信道资源的配置信息之前,所述UE可以将所述UE的分组信息上报给所述基站,令所述基站确定所述UE归属的分组。
可选的,所述UE接收的反馈信道资源的配置信息可以是通过公共信道接 收的。所述公共信道用于基站向分组内的UE配置反馈信道资源。
可选的,所述UE接收的反馈信道资源的配置信息可以指示所述UE不进行反馈,所述UE根据所述指示确定不进行反馈。
其中,所述UE与所述UE归属的分组内的其他UE配置的反馈信道资源和扰码可以相同,也可以不相同。例如,若所述基站在所述UE归属的分组内进一步划分了更细粒度的反馈组,则所述UE和与所述UE属于同一反馈组的其他UE之间配置的反馈信道资源和扰码相同,所述UE和与所述UE属于不同反馈组的其他UE之间配置的反馈信道资源和扰码不同。又例如,若所述基站在所述UE归属的分组内没有进一步划分反馈组,则所述UE和所述UE归属的分组内的其他UE均采用相同的反馈信道资源和扰码。
本发明实施例中,所述UE确定的所述基站为其配置的反馈信道资源,具体可以有但不限于以下两种配置方案:
方案一、
所述UE确定所述基站为所述UE配置的反馈信道资源为NACK反馈信道资源,所述NACK反馈信道资源用于所述UE在确定接收的所述数据错误时发送NACK给所述基站。
方案二、
所述UE确定所述基站为所述UE配置的反馈信道资源为下述信道资源中的任意组合:
ACK反馈信道资源,用于所述UE在确定接收的所述数据正确时发送ACK给所述基站;
NACK反馈信道资源,用于所述UE在确定接收的所述数据错误时发送NACK给所述基站;
参考功率发射信道资源,用于所述UE在确定接收到所述数据时发送预设的参考信号给所述基站。
步骤1202:所述UE接收所述基站发送的数据。
步骤1203:所述UE针对所述数据的接收情况,通过所述反馈信道资源 发送反馈信息给所述基站。
所述UE进行下行数据接收,并根据接收的数据信息是否正确以及反馈信道资源的配置方案,确定是否发送反馈信息或者发送何种反馈信息。
具体的,在上述方案一的配置方式下,当所述UE确定接收的所述数据正确时,不发送反馈信息给所述基站;当所述UE确定接收的所述数据错误时,通过所述NACK反馈信道资源发送NACK给所述基站。
而在上述方案二的配置方式下,如果所述UE确定所述基站为所述UE配置的反馈信道资源为ACK反馈信道资源和NACK反馈信道资源,则当所述UE确定接收的所述数据正确时,通过所述ACK反馈信道资源发送ACK给所述基站;当所述UE确定接收的所述数据错误时,通过所述NACK反馈信道资源发送NACK给所述基站。如果所述UE确定所述基站为所述UE配置的反馈信道资源为ACK反馈信道资源和参考功率发射信道资源,则当所述UE确定接收的所述数据正确时,通过所述ACK反馈信道资源发送ACK给所述基站;当所述UE确定接收到所述数据时,通过所述参考功率发射信道资源发送预设的参考信号给所述基站。如果所述UE确定所述基站为所述UE配置的反馈信道资源为NACK反馈信道资源和参考功率发射信道资源,则当所述UE确定接收的所述数据错误时,通过所述NACK反馈信道资源发送NACK给所述基站;当所述UE确定接收到所述数据时,通过所述参考功率发射信道资源发送预设的参考信号给所述基站。如果所述UE确定所述基站为所述UE配置的反馈信道资源为ACK反馈信道资源、NACK反馈信道资源和参考功率发射信道资源,则当所述UE确定接收的所述数据正确时,通过所述ACK反馈信道资源发送ACK给所述基站;当所述UE确定接收的所述数据错误时,通过所述NACK反馈信道资源发送NACK给所述基站;当所述UE确定接收到所述数据时,通过所述参考功率发射信道资源发送预设的参考信号给所述基站。
所述基站根据所述UE以及与所述UE属于同一分组的其他UE发送的反馈信息的功率确定是否对进行数据重传。当所述基站对所述分组内的UE发起数据重传时,所述分组内之前接收数据错误的UE需要重新进行数据接收。
综上所述,本发明上述各实施例提供的对UE进行组调度的技术方案,基站通过对UE进行分组,为同一组内的UE分配相同的反馈信道资源和扰码,以组为单位对UE进行调度,从而减少了占用的反馈信道资源和信令。
在LTE系统中,网络使用多播广播单频网络(英文:Multimedia Broadcast multicast service Single Frequency Network,简称:MBSFN)模式传送多媒体广播多播业务(英文:Multimedia Broadcast Multicast Service,简称:MBMS)业务。MBSFN包括用于传输控制信令的MBMS点到多点控制信道(英文:Multicast Control Channel,简称:MCCH),和用于传输业务数据的MBMS点到多点业务信道(英文:MBMS Traffic Channel,简称:MTCH),二者都映射到多播信道(英文:Multicast Channel,简称:MCH)上。MCCH的信息发生改变时,需要通知UE。并且MCCH有一个修改周期(英文:Modification Period,简称:MCCH MP),每个MCCH MP内包含一到多个重复周期,基站只能在MCCH MP边界处开始修改MCCH消息,同一MCCH MP内各个重复周期发送的MCCH消息是相同的。MCCH MP的长度是重复周期的整数倍。如果网络侧决定更新MCCH的内容,那么需要提前一个MCCH MP通知UE,然后在越过MCCH MP的边界后更新MCCH的内容。其中MCCH变更通知通过MBMS无线网络临时标识(英文:MBMS Radio Network Temporary Identification,简称:M-RNTI)发送给UE,其中包括一个8比特的MBSFN区域列表,每个比特对应一个MBSFN区域,UE可以根据这个列表确定哪个MBSFN区域对应的MCCH发生变化。
在现有系统中,MBMS业务和非MBMS业务都在同一个小区内传输,两类业务采用时分的方式,分别使用不同的子帧传送数据。网络侧通过系统广播将MBMS业务子帧的分布情况通知UE,UE可以根据系统消息确定所有的MBMS业务子帧。其中MBSFN子帧又分为MBSFN符号和非MBSFN符号,MBSFN子帧内的MBMS符号部分用于传输MBMS业务和控制信息,非MBSFN符号部分用于传输MCCH变更通知以及调度上行业务。并且MCCH变更通知只能在MBSFN子帧发送。
然而,LTE小区支持的多种带宽配置,包括了1.4M,5M,10M,20M这几种情况,具体带宽通过广播消息通知给UE。当小区带宽为1.4M时,MBSFN子帧包括的非MBSFN符号为2个,这个2个符号总共包括30个资源单元,而发送MCCH变更通知需要36个资源单元。这会导致UE无法接收MCCH变更通知。
为了解决小区带宽受限时UE可能无法接受MCCH变更通知的问题,本发明实施例还提供了一种MCCH消息发送和读取方法、基站和UE。
