  • Each terminal determines whether the terminal is scheduled in a subsequent PDSCH or PUSCH (Physical Uplink Shared Channel) by reading the scheduling signaling of the PDCCH on the corresponding coverage level. If the terminal determines that it is scheduled, The terminal transmits or receives data on the allocated resources (receives data on the PDSCH and transmits data on the PUSCH).
  • PDSCH Physical Uplink Shared Channel
  • the base station scheduling terminal After the base station scheduling terminal sends data on the PUSCH, in order to make the terminal aware of the data transmission Whether the transmission is correctly received by the base station, the base station needs to perform uplink feedback, that is, whether the uplink data feedback sent by the terminal is successfully received.

Description

一种针对上行信道的反馈方法及装置 技术领域
本发明涉及通信技术领域,尤其涉及一种针对上行信道的反馈方法及装置。
背景技术
MTC(Machine Type Communication,机器类型通信)技术将是未来通信领域的一项重要应用,预计到2022年,MTC设备的连接数量将达到500亿。MTC技术在未来可能涵盖如下领域:智能抄表、医疗检测、物流检测、火情检测以及可穿戴设备通信等领域。MTC通信系统中,基站和终端一般需要满足大覆盖、高连接数和低功耗的需求。
MTC通信系统中的下行信道的格式如图1A所示,横向代表时间,纵向代表频率。所述下行是从无线通信的基站到无线终端,简称终端的传输方向。下行信道主要有:
PDCCH(Physical Downlink Control Channel,物理下行控制信道):用于承载调度信息及其他控制信息;
PDSCH(Physical Downlink Shared Channel,物理下行共享信道):下行数据信道;
PBCH(Physical Broadcast Channel,物理广播信道):广播信道,用于承载系统消息;
PSCH(Physical Synchronization Channel,物理同步信道):下行同步信道。
每个终端通过读取对应覆盖等级上的PDCCH的调度信令,从而确定是否在后续的PDSCH或者PUSCH(Physical Uplink Shared Channel,物理上行共享信道)中调度了该终端,如果终端确定被调度,则终端在被分配的资源上发送或者接收数据(在PDSCH上接收数据,在PUSCH上发送数据)。
当基站调度终端在PUSCH上发送数据之后,为了使终端获知本次数据传 输是否被基站正确接收,基站要进行上行反馈,即针对终端发送的上行数据反馈是否接收成功。MTC通信系统中,上行反馈目前主要采用非Bitmap(位图)方式和Bitmap方式:
1)非Bitmap方式:对于终端发送的非最后一个数据包,基站通过在下一次调度命令中携带的指示字段表示相邻的上一个数据包的ACK/NACK信息;ACK表示接收正确,而NACK表示接收失败或不正确。对于最后一个数据包,基站不会再下发调度命令,用一个专用的消息来反馈针对该终端的最后一个数据包的ACK/NACK信息,在这种方式下,对于每一个终端的最后一个数据包,都要采用专用的消息来反馈ACK/NACK信息,因此,存在资源浪费的缺陷,例如,对于终端1,采用消息1来专门反馈针对终端1的最后一个数据包的ACK/NACK信息,对于终端2,采用消息2来专门反馈针对终端1的最后一个数据包的ACK/NACK信息,依次类推,因此,存在资源浪费的情况;
2)Bitmap方式:这种反馈方式针对多种终端,统一向所有终端反馈ACK/NACK信息,基站在每次调度终端的时候,在调度命令中指定这个终端与Bitmap消息中的哪个比特位相对应;例如,在图1B中,在第一个PDCCH周期内分别发送调度命令1、调度命令2、调度命令3和调度命令4,调度命令1用于调度终端3、调度命令2用于调度终端1、调度命令3用于调度终端2、调度命令4用于调度终端4,基站针对这次调度命令所接收到的上行数据的反馈是通过Bitmap消息来实现的,Bitmap消息中的第3个比特位与终端1相对应,第4个比特位与终端2相对应,第5个比特位与终端3相对应,第6个比特位与终端4相对应,在这种方式下,对于非最后一个数据包,由于要使用额外的Bitmap消息来反馈ACK/NACK信息,因此,也存在资源浪费的缺陷。
综上所述,目前进行针对上行信道的反馈方法存在资源浪费的缺陷。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的 范围。
下面对本发明实施例所适用的无线通信系统进行描述。
参阅图2A所示,无线通信系统包括基站或者接入点与无线终端,其中,基站或者接入点用于为至少一个无线终端提供通信服务,基站、接入点、或无线终端可以包括至少一个天线。无线终端可以为移动站、远程站、用户设备等,无线终端的具体形态可以为手机、平板电脑、个人数字助手等用户设备。
下面结合附图对本发明实施例进行详细说明。
参阅图2B所示,本发明实施例中,一种上行反馈的流程如下:
步骤200:基站判断终端发送的数据包是否是终端的最后一个数据包;若是,执行步骤210,否则,执行步骤220;
步骤210:基站在接收完终端发送的数据包后,向终端发送第一公共消息,第一公共消息包括反馈信息,反馈信息能够承载针对包括终端在内的至少两个终端的至少两个指示位,至少两个指示位中包括用于指示基站是否正确接收终端发送的数据包的指示位;
步骤220:基站在接收完终端发送的数据包后,向终端发送第一调度命令,第一调度命令包括用于指示基站是否正确接收终端发送的数据包的指示位,第一调度命令用于调度终端重新发送数据包或者发送下一个新的数据包。
在该方案中,基站判断终端发送的数据包是否是终端的最后一个数据包后,才决定发送包括用于指示基站是否正确接收终端发送的数据包的指示位的消息是第一调度命令还是第一公共消息,不是在任何情况下都一直发送第一公共消息或者第一调度命令因此,避免了资源的浪费。
本发明实施例中,第一调度命令包括的用于指示基站是否正确接收终端发送的数据包的指示位,可以是直接指示是否正确接收终端发送的数据包的指示位,也可以指间接指示是否正确接收终端发送的数据包的指示位,例如,该指示位指示的是下一个数据包的编号,通过下一个数据包的编号来指示是否正确接收终端发送的数据包。如果指示位指示的不是下一个数据包编号, 而仍然是前一次的数据包,说明前一次的数据包没有被正确接收。
可选的,反馈信息可以是一个bitmap,其中反馈信息中的一个资源位置即是一个bit位置,每个bit位置可以分配给一个终端;或者反馈信息承载在一段共享资源上,不同的终端通过码分进行资源复用(CDMA),反馈信息中的一个资源位置即对应一个码资源,每一个码资源可以分配给一个终端用来承载ACK/NACK信息或其他信令。
本发明实施例中,基站判断终端发送的数据包是否是终端的最后一个数据包时,可选的,可以采用如下方式:
基站根据终端反馈的BSR(Buffer Status Report,缓存状态报告),判断缓存状态报告对应的缓存状态是否超过阈值;
若是,基站判定终端发送的数据包不是终端的最后一个数据包;
否则,基站判定终端发送的数据包是终端的最后一个数据包。
本发明实施例中,进一步的,基站判断终端发送的数据包是否是终端的最后一个数据包之后,接收终端发送的数据包之前,还包括如下操作:
基站向终端发送第二调度命令,第二调度命令还用于指示为终端分配的发送数据包的上行资源;
基站接收终端在上行资源上发送的数据包。
本发明实施例中,还包括如下操作:
基站向终端发送第二调度命令,第二调度命令包括反馈资源指示信息;
若基站判断终端发送的数据包是终端的最后一个数据包,反馈资源指示信息指示终端在发送完数据包后,从第一公共消息中获取反馈信息,并指示用于指示基站是否正确接收终端发送的数据包的指示位在至少两个指示位中的位置;
若基站判断终端发送的数据包不是终端的最后一个数据包,反馈资源指示信息指示终端在发送完数据包后,从第一调度命令中获取用于指示基站是否正确接收终端发送的数据包的指示位。
例如,反馈信息是针对4个终端的,其中,反馈信息中的第一指示位与 终端1对应,反馈信息中的第二指示位与终端2对应,反馈信息中的第三指示位与终端3对应,那么反馈信息中的第一指示位指示针对终端1的数据包的ACK/NACK信息,反馈信息中的第二指示位指示针对终端2的数据包的ACK/NACK信息,反馈信息中的第三指示位指示针对终端3的数据包的ACK/NACK信息。
需要说明的是,虽然终端发送的反馈信息可以是针对至少两个终端的,但在实际应用中,反馈信息可能只是针对一个终端。
需要说明的是,为了使终端知道是根据第一公共消息来确定ACK/NACK信息,还是根据第一调度命令来确定ACK/NACK信息,基站可以通过使用不同的指示方式来指示。一种方式是在调度命令中使用标志位来指示,如果标志位为“1”,则终端根据第一调度命令来确定ACK/NACK信息,如果标志位为“0”,则终端根据第一公共消息来确定ACK/NACK信息,并根据预设准则或者调度命令中的指示确定终端在反馈信息中对应的指示位。另一种方式是使用不同的调度命令格式来区分,终端通过盲检测确定接收到的指示消息的类型,如果是第一指示消息类型,则使用第一公共消息来确定ACK/NACK消息,如果是第二指示消息类型,则终端根据第一调度命令来确定ACK/NACK信息。
参阅图3所示,本发明实施例中,一种针对上行信道的反馈的流程如下:
步骤300:终端接收基站向终端发送的第二调度命令,第二调度命令中包含反馈资源指示信息;
步骤310:若反馈资源指示信息指示终端在发送完数据包后,从第一公共消息中获取反馈信息,并指示用于指示基站是否正确接收终端发送的数据包的指示位在至少两个指示位中的位置,终端从至少两个指示位中对应指示位上获取基站是否正确接收数据包的指示,以判断基站是否正确接收终端发送的数据包,反馈信息能够承载针对包括终端在内的至少两个终端的至少两个指示位,至少两个指示位中包括用于指示基站是否正确接收终端发送的数据包的指示位;
步骤320:若反馈资源指示信息指示终端在发送完数据包后,从第一调度命令中获取用于指示基站是否正确接收终端发送的数据包的指示位,终端从第一调度命令中对应指示位上获取基站是否正确接收终端发送的数据包的指示,以判断基站是否正确接收终端发送的数据包,第一调度命令包括用于指示基站是否正确接收终端发送的数据包的指示位,第一调度命令用于调度终端重新发送数据包或者发送下一个新的数据包。
在该方案中,基站判断终端发送的数据包是否是终端的最后一个数据包后,才决定发送包括用于指示基站是否正确接收终端发送的数据包的指示位的消息是第一调度命令还是第一公共消息,不是在任何情况下都一直发送第一公共消息或者第一调度命令,因此,避免了资源浪费。
本发明实施例中,第一调度命令包括的用于指示基站是否正确接收终端发送的数据包的指示位,可以是直接指示是否正确接收终端发送的数据包的指示位,也可以指间接指示是否正确接收终端发送的数据包的指示位,例如,该指示位指示的是下一个数据包的编号,通过下一个数据包的编号来指示是否正确接收终端发送的数据包。
可选的,反馈信息可以是一个bitmap,其中反馈信息中的一个资源位置即是一个bit位置,每个bit位置可以分配给一个终端;或者反馈信息承载在一段共享资源上,不同的终端通过码分进行资源复用(CDMA),反馈信息中的一个资源位置即对应一个码资源,每一个码资源可以分配给一个终端用来承载ACK/NACK信息或其他信令。
本发明实施例中,终端在接收基站向终端发送的第二调度命令之前,还包括如下操作:
终端向基站反馈缓存状态报告。
本发明实施例中,可选的,第二调度命令用于指示为终端分配的发送数据包的上行资源;
方法还包括如下操作:
终端在第二调度命令中为终端分配的上行资源上,向基站发送数据包。
例如,反馈信息是针对4个终端的,其中,反馈信息中的第一指示位与终端1对应,反馈信息中的第二指示位与终端2对应,反馈信息中的第三指示位与终端3对应,那么反馈信息中的第一指示位指示针对终端1的数据包的ACK/NACK信息,反馈信息中的第二指示位指示针对终端2的数据包的ACK/NACK信息,反馈信息中的第三指示位指示针对终端3的数据包的ACK/NACK信息。
需要说明的是,虽然终端发送的反馈信息可以是针对至少两个终端的,但在实际应用中,反馈信息可能只是针对一个终端。
需要说明的是,为了使终端知道是根据第一公共消息来确定ACK/NACK信息,还是根据第一调度命令来确定ACK/NACK信息,基站可以通过使用不同的指示方式来指示。一种方式是在调度命令中使用标志位来指示,如果标志位为“1”,则终端根据第一调度命令来确定ACK/NACK信息,如果标志位为“0”,则终端根据第一公共消息来确定ACK/NACK信息,并根据预设准则或者调度命令中的指示确定终端在第一公共消息中对应的指示位。另一种方式是使用不同的调度命令格式来区分,终端通过盲检测确定接收到的指示消息的类型,如果是第一指示消息类型,则使用第一公共消息来确定ACK/NACK消息,如果是第二指示消息类型,则终端根据第一调度命令来确定ACK/NACK信息。

本发明实施例中,若基站判定终端在发送数据包之后需要发送下一个数据包或者数据包需要重传,方法还包括如下操作:
基站向终端发送第一调度命令,第一调度命令用于调度终端重新发送数据包或者发送下一个数据包,第一调度命令包括用于指示基站是否正确接收终端发送的数据包的指示位。
也就是说,当终端需要发送下一个数据包或者数据包需要重传时,通过第一调度命令来指示基站是否正确接收终端发送的数据包,而反馈信息中的至少两个指示位中针对终端的指示位用于指示上行控制信息,因此,该方案避免了资源的浪费。
上述描述的是,基站判定终端在发送数据包之后有下一个数据包需要发送或数据包需要重传的情况,在实际应用中,还可能包括基站判定终端在发送数据包之后无下一个数据包需要发送或数据包不需要重传的情况,本发明实施例中,方法还包括如下操作:
基站判定终端在发送数据包之后无下一个数据包需要发送,且数据包不需要重传时,基站向终端发送第一公共消息,第一公共消息包括反馈信息,反馈信息能够承载针对包括终端在内的至少两个终端的至少两个指示位,至少两个指示位中针对终端的指示位用于指示基站是否正确接收数据包。
本发明实施例中,基站判定终端在发送数据包之后无下一个数据包需要发送时,可选的,可以采用如下方式:
基站根据数据包中携带的指示标识,判定终端在发送数据包之后没有下一个数据包需要发送,指示标识指示数据包发送完成后,终端没有下一个数据包需要发送。

若基站判断终端发送的数据包不是终端的最后一个数据包,反馈资源指示信息指示终端在发送完数据包后,从第一调度命令中获取用于指示基站是否正确接收终端发送的数据包的指示位。
可选的,反馈信息可以是一个bitmap,其中反馈信息中的一个资源位置即是一个bit位置,每个bit位置可以分配给一个终端;或者反馈信息承载在一段共享资源上,不同的终端通过码分进行资源复用(CDMA),反馈信息中的一个资源位置即对应一个码资源,每一个码资源可以分配给一个终端用来承载ACK/NACK信息或其他信令。
上行控制信息,包括但不限于上行功控命令。

步骤500:终端向基站发送数据包;
步骤510:终端在发送数据包之后,有下一个数据包需要发送时,接收基站发送的第一公共消息,第一公共消息包括反馈信息,反馈信息能够承载针对包括终端在内的至少两个终端的至少两个指示位,至少两个指示位中针对终端的指示位用于指示上行控制信息;
