Description

提前终止传输方法及装置 技术领域
本公开涉及通信领域,尤其涉及提前终止传输方法及装置。
背景技术
相关技术中,3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)release 16(版本16)中提出了可以由一个PDCCH(Physical Downlink Control Channel,物理下行控制信道)连续调度多个上行或下行TB(Transmission Block,数据块),如图1A所示。考虑到在MTC(Machine Type Communication,机器类通信)中可能存在重复传输的情况,调度方式则如图1B所示。
另外,为了增加时间分集效果,提高传输效率,在多TB调度中可以使用交替传输的机制,即终端交替向基站重复传输不同的TB,如图1C所示。
在相关技术中,基站可以根据终端的信道状况为终端配置交替重复传输多个不同TB的最大次数。但是由于信道测量的误差性和信道的波动性等因素,终端可能在交替重复上传多个不同TB的总次数小于所述最大次数时,基站就已经成功解调了多个不同的TB。但是,终端仍会继续重复交替上传多个不同的TB,直到所述总次数达到所述最大次数为止,如图2所示。这样就带来了额外的MTC终端功率消耗。

本公开的实施例提供的技术方案可以包括以下有益效果:
本公开实施例中,MTC系统中的基站可以在接收到的终端重复上传的第一数据单元的总次数未达到第一目标次数之前,确定是否成功解调所述第一数据单元中所包括的所有数据块。如果在所述终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,确定成功解调所述第一数据单元中所包括的所有数据块,则发送目标下行控制信息DCI到所述终端,终端会根据目标DCI提取终止上传第一数据单元到所述基站。在本公开实施例中,可以在基站成功解调第一数据单元所包括的所有数据块时,发送目标DCI到终端,指示终端提前终止传输第一数据单元到基站,从而在终端重复交替上传不同的多个数据块的情况下,实现了提前终止传输的目的,有利于节省MTC系统终端的资源。
本公开实施例中,目标DCI至少需要包括提前终止指示域,以便终端根据提前终止指示域确定提前终止上传第一数据单元到基站,可用性高。
本公开实施例中,MTC系统中的终端在重复交替上传多个不同的数控块,即重复上传第一数据单元的情况下,可以根据基站成功解调第一数据单元所包括的所有数据块之后发送的目标DCI,提前终止上传第一数据单元到基站,从而可以大大节省终端资源。
本公开实施例中,MTC系统中的基站还可以在终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,如果确定成功解调第一数据单元中预设数目的数据块,就可以发送目标DCI到终端,指示终端提前终止传输第一数据单元到基站。在上述实施例中,在终端重复交替上传不同的多个数据块的情况下,基站可以在成功解调终端重复交替上传的部分数据块时就发送目标DCI到终端,来提前终止终端上传第一数据单元,有利于节省MTC系统终端的资源。
本公开实施例中,可以由基站将通信协议中预定义的所述基站需要在所述第一数据单元中成功解调的数据块的数目作为所述预设数目,或者由基站通过第一预设信令为终端配置所述预设数目。通过上述过程,可以根据通信协议或基站自身的需要来确定预设数目,实现简便,可用性高。
本公开实施例中,基站需要为终端配置第一目标时间单元编号和第二目标时间单元编号,从而在基站侧和终端侧统一确定停止接收第一数据单元的时间点和开始接收第二数据单元的时间点,便于基站与终端之间进行数据交互,避免遗漏数据影响终端业务,且可以有效节省基站侧资源和终端资源。
本公开实施例中,第一目标时间单元需要满足第一目标条件,所述第一目标条件包括所述终端在接收到所述目标DCI之后重复上传所述第一数据单元的次数最少,且所述第一数据单元所包括的每个数据块各自对应的已经重复上传的总次数相同;对应的时间单元编号大于或等于第一和值,所述第一和值是所述终端接收到所述目标 DCI的最后一个时间单元所对应的时间单元编号与第一时间偏移量值的和值。从而可以在终端接收到目标DCI之后,完整传输第一数据单元之后,停止上传第一数据单元,确保了基站和终端的传输质量,有利于节省基站和终端的资源。
本公开实施例中,同样地,第二目标时间单元是满足第二目标条件的时间单元;所述第二目标条件包括:在所述第一目标时间单元之后,所述终端重复上传所述第二数据单元的第一个时间单元;对应的时间单元编号大于或等于第二和值,所述第二和值是所述终端接收到所述目标DCI的最后一个时间单元所对应的时间单元编号与第二时间偏移量值的和值,或者所述第二和值是第一目标时间单元编号与第三时间偏移量值的和值,所述第二时间偏移量值和所述第三时间偏移量值均大于所述第一时间偏移量值。采用上述方式确定第二目标时间单元之后,可以确保在终端停止上传第一数据单元之后在第二目标时间单元开始重复上传第二数据单元,确保基站和终端的传输质量,有利于节省基站和终端的资源。
本公开实施例中,基站还可以将通信协议中预定义的所述终端提前终止重复上传所述第一数据单元时所对应的时间偏移量值作为所述第一时间偏移量值,或者通过不同的预设信令为所述终端配置所述第一时间偏移量值。通过上述过程,基站侧可以快速确定第一时间偏移量,实现简便,可用性高,便于后续准确确定停止接收第一数据单元的时间点。
本公开实施例中,基站还可以根据通信协议中预定义的第一时间偏移量值与第二时间偏移量值之间的对应关系和所述第一时间偏移量值,计算所述第二时间偏移量值,或者通过第一预设信令或第二预设信令为所述终端配置所述第二时间偏移量值,所述第二时间偏移量值大于所述第一时间偏移量值。本公开实施例中,基站确定第三时间偏移量值的方式与确定第二时间偏移量值的方式相同。通过上述过程,基站侧可以快速确定第二时间偏移量或第三时间偏移量值,实现简便,可用性高,便于后续准确确定开始接收第二数据单元的时间点。
本公开实施例中,基站发送的目标DCI中至少包括提前终止指示域和与所述第一数据单元中成功解调的数据块所对应的混合自动重传请求HARQ进程号,便于终端根据提前终止指示域来提前终止上传第一数据单元到基站,且便于终端根据目标DCI中携带的HARQ进程号,确定基站在所述第一数据单元中成功解调的数据块,有利于后续基站与终端之间的数据交互。
本公开实施例中,基站发送的目标DCI中还可以包括第二目标次数;所述第二目标次数是所述终端重复上传所述第二数据单元的最大次数,且所述第二目标次数小于所述第一目标次数。基站通过目标DCI对终端后续上传第二数据单元的重复上传次数进行调整,提高了后续第二数据单元的传输效率。
本公开实施例中,基站可以为终端配置备选次数集合,进而通过目标DCI在备选次数集合中指定一个数值作为所述第二目标次数对应的数值。或者,基站可以为终端配置备选偏移量集合,进而通过目标DCI在所述备选偏移量集合中选取一个作为目标偏移量对应的数值,由所述终端根据所述第一目标次数和所述目标偏移量,计算得到所述第二目标次数。通过上述过程,可以让基站根据当前信道状况,调整第二数据单元的重复上传次数,提高了传输效率,可用性高。
本公开实施例中,终端可以重复交替上传不同的数据块到基站,即重复上传第一数据单元到基站,基站如果在终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,确定成功解调了第一数据单元中预设数目的数据块,则基站会发送目标DCI到终端,终端可以根据目标DCI,停止重复上传第一数据单元到基站之后,开始重复上传第二数据单元到基站。通过上述过程,实现了在终端重复交替上传不同的多个数据块的情况下,基站可以在成功解调终端重复交替上传的部分数据块时就发送目标DCI到终端,来提前终止终端上传第一数据单元的目的,有利于节省MTC系统终端的资源。

针对相关技术中基站成功解调终端上传的所有不同的数据块之后,终端仍继续交替上传不同的数据块直到达到最大次数的问题,可以由基站在成功解调终端上传的所有不同的数据块之后,发送提前终止传输指示给终端。本公开实施例针对终端交替上传多数据块的情况,提出以下两种方案进行提前终止传输。
第一种方案,基站成功解调终端上传的第一数据单元所包括的所有TB之后,发送目标DCI到终端,由终端根据目标DCI提前终止上传第一数据单元到基站。
下面先从MTC系统中的基站侧来介绍第一种方案。
本公开实施例提供了一种提前终止传输方法,可以用于机器类通信MTC系统中的基站。参照图3所示,图3是根据一示例性实施例示出的一种提前终止传输方法流程图,可以包括以下步骤:
在步骤101中,接收MTC系统中的终端重复上传的第一数据单元;所述第一数据单元包括所述终端当前需要传输给所述基站进行解调的多个互不相同的数据块;
在步骤102中,在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,确定是否成功解调所述第一数据单元中所包括的所有数据块;所述第一目标次数是由所述基站为所述终端配置的重复上传所述第一数据单元的最大次数;
在步骤103中,如果在所述终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,确定成功解调所述第一数据单元中所包括的所有数据块,则发送目标下行控制信息DCI到所述终端;所述目标DCI用于指示所述终端提前终止上传所述第一数据单元到所述基站。
上述实施例中,可以在基站成功解调第一数据单元所包括的所有数据块时,发送目标DCI到终端,指示终端提前终止传输第一数据单元到基站,从而在终端重复交替上传不同的多个数据块的情况下,实现了提前终止传输的目的,有利于节省MTC系统终端的资源。
针对上述步骤101,假设终端当前需要基站解调的数据块包括4个互不相同的数据块TB1、TB2、TB3和TB4。则TB1、TB2、TB3和TB4组成了第一数据单元,终端重复上传第一数据单元到基站,基站则按照相关技术重复接收所述第一数据单元,如图4所示。
针对上述步骤102,基站可以预先为终端配置重复上传所述第一数据单元的最大次数,即为所述终端配置第一目标次数,例如第一目标次数配置为32次,则终端最多可以重复上传32次第一数据单元到基站。
基站可以在每次接收到第一数据单元之后,均会按照相关技术对第一数据单元所包括的所有数据块尝试进行解调。针对上述步骤103,假设基站为终端配置的所述第一目标次数为32,基站在接收到终端重复上传所述第一数据单元的总次数达到20次时,就成功解调了第一数据单元所包括的所有数据块,则此时基站可以发送目标DCI到终端,指示终端无需继续上传第一数据单元到基站,从而节省MTC终端资源,同样如图4所示。
在一实施例中,基站配置的目标DCI指示包括提取终止指示域,可选地,基站 可以采用以下方式来配置所述目标DCI中的所述提前终止指示域:
在覆盖条件较好的第一覆盖增强模式下,例如MTC系统中的覆盖增强模式A下,基站可以将目标DCI中预先指定的5比特物理资源块的资源均设置为1,终端在接收到目标DCI之后,确定需要提前终止传输第一数据单元。
另外,在覆盖条件较差的第二覆盖增强模式下,例如MTC系统中的覆盖增强模式B下,基站可以将目标DCI中预先指定的4比特调制编码方式域对应的资源均设置为1,终端在接收到目标DCI之后,确定需要提前终止传输第一数据单元。
在本公开实施例中,第一预设值和第二预设值可以相同或不同,本公开对此不做限制。
在上述实施例中,目标DCI至少需要包括提前终止指示域,以便终端根据提前终止指示域确定提前终止上传第一数据单元到基站,可用性高。
下面再从MTC系统中的终端侧来介绍上述第一种方案。
本公开实施例提供了一种提前终止传输方法,可以用于机器类通信MTC系统中的终端。参照图5所示,图5是根据一示例性实施例示出的一种提前终止传输方法流程图,可以包括以下步骤:
在步骤201中,重复上传第一数据单元到MTC系统中的基站,所述第一数据单元包括所述终端当前需要传输给所述基站进行解调的多个互不相同的数据块;
在步骤202中,如果在重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,接收到所述基站发送的目标下行控制信息DCI,则提前终止上传所述第一数据单元到所述基站;所述第一目标次数是由所述基站为所述终端配置的重复上传所述第一数据单元的最大次数。
上述实施例中,MTC系统中的终端在重复交替上传多个不同的数控块,即重复上传第一数据单元的情况下,可以根据基站成功解调第一数据单元所包括的所有数据块之后发送的目标DCI,提前终止上传第一数据单元到基站,从而可以大大节省终端资源。
针对上述步骤201,
例如,终端当前需要基站解调的数据块包括4个互不相同的数据块TB1、TB2、TB3和TB4。则TB1、TB2、TB3和TB4组成了第一数据单元,终端重复上传第一数据单元到基站。
针对上述步骤202,假设基站为终端配置的第一目标次数为32。基站在接收第一数据单元的总次数未达到第一目标次数,即未达到32次之前,就成功解调了第一数据单元所包括的所有数据块,则基站会下发目标DCI到终端。
终端按照相关技术接收到目标DCI之后,如果处于当前覆盖条件较好的第一增强覆盖模式下,例如MTC系统中的覆盖增强模式A下,终端可以查找目标DCI预先指定的5比特物理资源块的资源所对应的数值是否为1,如果为1,确定该DCI为目标DCI,且需要根据提前终止指示域的指示提前终止传输第一传输单元到基站。
另外,终端按照相关技术接收到目标DCI之后,如果处于当前覆盖条件较差的第二增强覆盖模式下,例如MTC系统中的覆盖增强模式B下,终端可以查找目标DCI预先指定的4比特调制编码方式域对应的资源所对应的数值是否为1,如果为1,确定该DCI为目标DCI,且需要根据提前终止指示域的指示提前终止传输第一传输单元到基站。
上述实施例中,MTC系统中的终端在重复交替上传多个不同的数控块,即重复上传第一数据单元的情况下,可以根据基站成功解调第一数据单元所包括的所有数据块之后发送的目标DCI,提前终止上传第一数据单元到基站,从而可以大大节省终端资源。
本公开实施例还提供了另一种提前终止传输方法。参照图6所示,图6是根据一示例性实施例示出的另一种提前终止传输方法流程图,可以包括以下步骤:
在步骤301中,MTC系统中的终端重复上传第一数据单元到MTC系统中的基 站。
其中,所述第一数据单元包括所述终端当前需要传输给所述基站进行解调的多个互不相同的数据块。
在步骤302中,所述基站在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,确定是否成功解调所述第一数据单元中所包括的所有数据块。
在步骤303中,所述基站在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,确定成功解调所述第一数据单元中所包括的所有数据块,发送目标DCI到终端。
其中,第一目标次数是由所述基站为所述终端配置的重复上传所述第一数据单元的最大次数。所述目标DCI至少包括提前终止指示域,基站可以采用以下方式配置所述目标DCI中的所述提前终止指示域:
在覆盖条件较好的第一覆盖增强模式下,将所述目标DCI中预先指定的物理资源块对应的资源作为所述提前终止指示域,且将所述提前终止指示域配置为第一预设值,其中,所述第一预设值为1;
在覆盖条件较差的第二覆盖增强模式下,将所述目标DCI中预先指定的调制编码方式域对应的资源作为所述提前终止指示域,且将所述提前终止指示域配置为第二预设值,其中,所述第二预设值为1。
在步骤304中,所述终端接收到所述目标DCI,则提前终止上传所述第一数据单元到所述基站。
上述实施例中,当终端向基站交替上传多个不同的数据块时,即重复上传第一数据单元时,基站在终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,成功解调第一数据单元中所包括的所有数据块时才下发目标DCI到终端,来指示终端提前终止上传第一数据单元到基站。在终端重复交替上传不同的多个数据块的情况下,实现了提前终止传输的目的,有利于节省MTC系统终端的资源。
上述提取终止传输方案需要基站对第一数据单元所包括的所有数据块成功解调之后,发送目标DCI到终端,来提前终止终端继续重复上传第一数据单元,在本公开实施例中,可选地,还可以在基站对第一数据单元所包括的部分数据块成功解调时,就提前终止终端继续重复上传第一数据单元。本公开提供的另一种提前终止传输方案如下。
第二种方案,基站可以在成功解调终端上传的第一数据单元中预设数目的数据块之后,发送目标DCI到终端,指示终端提前终止传输第一数据单元到基站之后,重复上传第二数据单元到基站。
下面先从MTC系统中的基站侧来介绍第二种方案。
本公开实施例提供了另一种提前终止传输方法,可以用于机器类通信MTC系统中的基站。参照图7所示,图7是根据一示例性实施例示出的另一种提前终止传输方法流程图,可以包括以下步骤:
在步骤401中,接收MTC系统中的终端重复上传的第一数据单元;所述第一数据单元包括所述终端当前需要传输给所述基站进行解调的多个互不相同的数据块;
在步骤402中,在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,确定是否成功解调所述第一数据单元所包括的预设数目的数据块;所述第一目标次数是由所述基站为所述终端配置的重复上传所述第一数据单元的最大次数;
在步骤403中,如果在所述终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,确定成功解调所述第一数据单元所包括的预设数目的数据块,则发送目标下行控制信息DCI到所述终端;
其中,所述目标DCI用于指示所述终端提前终止上传所述第一数据单元到所述基站之后,重复上传第二数据单元到所述基站,所述第二数据单元包括所述第一数据单元中除了所述基站已经成功解调的数据块之外的所有数据块。
上述实施例中,MTC系统中的基站还可以在终端重复上传所述第一数据单元 的总次数未达到所述第一目标次数之前,如果确定成功解调第一数据单元中预设数目的数据块,就可以发送目标DCI到终端,指示终端提前终止传输第一数据单元到基站。在上述实施例中,在终端重复交替上传不同的多个数据块的情况下,基站可以在成功解调终端重复交替上传的部分数据块时就发送目标DCI到终端,来提前终止终端上传第一数据单元,有利于节省MTC系统终端的资源。
针对上述步骤401,假设终端当前需要基站解调的数据块包括4个互不相同的数据块TB1、TB2、TB3和TB4。则TB1、TB2、TB3和TB4组成了第一数据单元,终端重复上传第一数据单元到基站,基站则按照相关技术重复接收所述第一数据单元,同样如图4所示。
针对上述步骤402,假设第一目标次数配置为32次,则终端最多可以重复上传32次第一数据单元到基站。
基站可以在每次接收到第一数据单元之后,按照相关技术对第一数据单元所包括的所有数据块尝试进行解调。在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,基站可以确定是否成功解调了第一数据单元中的部分数据块,例如预设数目的数据块。预设数目可以为1,2,3……。
针对上述步骤403,例如,基站为终端配置的所述第一目标次数为32,基站在接收到终端重复上传所述第一数据单元的总次数达到20次时,就成功解调了第一数据单元中预设数目的数据块,假设预设数目为2,则此时基站可以发送目标DCI到终端,让终端无需继续上传第一数据单元到基站,从而节省MTC终端资源。
在本公开实施例中,如果终端停止重复上传第一数据单元了,但是第一数据单元中还有部分数据块未被基站成功解调,还需要继续传输给基站,避免基站漏掉数据,影响终端业务。因此,终端在提前终止上传第一数据单元到基站之后,可以继续重复上传第二数据单元到基站,其中,所述第二数据单元包括所述第一数据单元中除了所述基站已经成功解调的数据块之外的所有数据块。这样基站就可以继续对所述第一数据单元中未成功解调的数据块进行解调。
例如,第一数据单元中包括4个互不相同的数据块TB1、TB2、TB3和TB4。预设数目为2,基站为终端配置的所述第一目标次数为32,基站在接收到终端重复上传所述第一数据单元的总次数达到20次时,就成功解调了第一数据单元中的2个数据块TB2和TB3,此时基站可以发送目标DCI到终端,终端提前终止上传第一数据单元到基站之后,开始重复上传第二数据单元到基站,所述第二数据单元包括TB1和TB4。这样基站可以继续对第二数据单元所包括的所有数据块TB1和TB4进行解调,直到全部解调成功。
上述实施例中,在终端重复交替上传不同的多个数据块的情况下,基站可以在成功解调终端重复交替上传的部分数据块时就发送目标DCI到终端,来提前终止终端上传第一数据单元,有利于节省MTC系统终端的资源。
在一实施例中,基站可以采用以下方式中的任意一种来确定预设数目。
第一种方式,将通信协议中预定义的所述基站需要在所述第一数据单元中成功解调的数据块的数目作为所述预设数目。
在本公开实施例中,可以在MTC系统的基站和终端的底层协议中预定义所述基站需要在所述第一数据单元中成功解调的数据块的数目,基站在需要确定所述预设数目时,可以直接将预定义的所述基站需要在所述第一数据单元中成功解调的数据块的数目作为所述预设数目。
第二种方式,由基站通过第一预设信令为所述终端配置所述预设数目。
其中,可选地,所述第一预设信令可以是高层的RRC(Radio Resource Control,无线资源控制)信令。
所述基站可以通过RRC信令为终端来配置预设数目,当然,预设数目的数值小于第一数据单元所包括的所有数据块的总数目。
上述实施例中,可以根据通信协议或基站自身的需要来确定预设数目,实现简 便,可用性高。
在一实施例中,参照8所示,图8是根据图7所示的实施例示出的另一种提前终止传输方法流程图,所述方法还可以包括:
在步骤404中,为所述终端分别配置第一目标时间单元编号和第二目标时间单元编号;
在本公开实施例中,涉及到的时间单元可以为子帧、时隙等。
下面先介绍一下基站如何确定第一目标时间单元编号。
本公开实施例中,需要在终端接收到目标DCI之后,基站提前终止接收第一数据单元,因此,第一目标时间单元应位于目标DCI之后。为了便于基站与终端之间的数据交互,可以让终端重复上传第一数据单元所包括的每个数据块的总次数相同。即确保终端在提前终止传输第一数据单元之前,重复上传的第一数据单元所包括的所有数据块的总次数相同。另外,终端在接收到目标DCI之后,除了确保重复上传的第一数据单元所包括的每个数据块的总次数相同之外,为了节省终端资源,还可以控制终端重复上传第一数据单元的次数最少。
在本公开实施例中,除了上述条件外还需要确保第一目标时间单元对应的时间单元编号,即第一目标时间单元编号大于或等于第一和值,所述第一和值可以采用所述目标DCI的最后一个时间单元所对应的时间单元编号与第一时间偏移量值之间的和值。
例如,终端接收到目标DCI的最后一个时间单元在第18个时间单元编号对应的时间单元上,则目标DCI的最后一个时间单元所对应的时间单元编号就为18。
基站在确定第一时间偏移量时,可以采用以下方式中的任意一种。
第一种方式,将通信协议中预定义的所述终端提前终止重复上传所述第一数据单元时所对应的时间偏移量值直接作为所述第一时间偏移量值。
假设第一数据单元包括4个数据块,通信协议中预定义了所述终端提前终止重复上传所述第一数据单元时所对应的时间偏移量值为4,则第一时间偏移量值就为4。
第二种方式,由基站直接通过第一预设信令或第二预设信令为所述终端配置所述第一时间偏移量值。
其中,第一预设信令可以是高层RRC信令,第二预设信令可以是物理层的MAC(Media Access Control,媒体访问控制)信令。
假设目标DCI的最后一个时间单元所对应的时间单元编号为18,第一时间偏移量值为5,则第一目标时间单元编号需要大于第一和值18+5=23。
对上述实施例进一步举例说明如下。
假设第一数据单元所包括的数据块总数目为4,第一和值为23,目标DCI的最后一个时间单元所对应的时间单元编号为18,则第一目标时间单元编号需要大于或等于23,且第一目标单元需要确保终端上传的第一数据单元所包括的每个数据块重复上传的总次数相同,上传第一数据单元的次数最少。因此,最终可以确定第一目标时间单元为23。
下面再介绍一下基站如何确定第二目标时间单元编号。
终端接收到目标DCI的最后一个时间单元在第18个时间单元编号对应的时间单元上,则目标DCI的最后一个时间单元所对应的时间单元编号就为18。
进一步地,基站可以采用以下方式中的任意一种确定第二时间偏移量值。
第一种方式,根据通信协议中预定义的第一时间偏移量值与第二时间偏移量值之间的对应关系和所述第一时间偏移量值,计算所述第二时间偏移量值。
例如第二时间偏移量值可以是第一时间偏移量值加1。基站可以根据上述对应关系和之前确定的第一时间偏移量值,计算得到第二时间偏移量值。第一时间偏移量值为5,则第二时间偏移量值可以为6。
第二种方式,由基站通过第一预设信令或第二预设信令为所述终端配置所述第二时间偏移量值。
其中,第一预设信令可以是RRC信令,第二预设信令可以是MAC信令。基站可以根据第一时间偏移量值来为终端配置第二时间偏移量值。例如,第一时间偏移量值为5,由于所述第二时间偏移量值大于所述第一时间偏移量值,则基站可以为终端将第二时间偏移量值配置为6。
基站可以在确定了目标DCI的最后一个时间单元所对应的时间单元编号和第二时间偏移量之后,计算两者的第二和值,第二目标时间单元编号需要大于或等于第二和值。例如,目标DCI的最后一个时间单元所对应的时间单元编号为18,第二时间单元偏移量为6,则第二目标时间单元编号需要大于或等于24。
或者基站可以直接计算第一目标时间单元编号和第三时间偏移量之和,将该和值作为第二和值。其中,基站确定第三时间偏移量值的方式与确定第二时间偏移量值的方式相同,在此不再赘述。且在本公开实施例中,第三时间偏移量值与第二时间偏移量值可以相同或不同。
例如第一目标时间单元编号为23,第三时间单元偏移量为6,则第二和值为29,第二目标时间单元编号需要相应地大于或等于29。
当然,第二目标时间单元还需要在第一目标时间单元之后,作为终端重复上传第二数据单元的第一个时间单元,因此,如果第一目标时间单元编号为23,第二目标时间单元编号大于或等于24,则可以将第二目标时间单元编号确定为24。
在步骤405中,在所述第一目标时间单元的下一个时间单元开始停止对所述第一数据单元的接收;
本步骤中,第一目标时间单元编号如果为23,则基站可以在第24个时间单元上停止接收终端重复上传的第一数据单元。
在步骤406中,在所述第二目标时间单元开始接收所述第二数据单元;
本步骤中,如果第二目标时间单元编号为24,则基站可以在第24个时间单元上开始接收终端重复上传的第二数据单元。
上述实施例中,基站需要为终端配置第一目标时间单元编号和第二目标时间单元编号,从而在基站侧和终端侧统一确定停止接收第一数据单元的时间点和开始接收第二数据单元的时间点,便于基站与终端之间进行数据交互,避免遗漏数据影响终端业务,且可以有效节省基站侧资源和终端资源。
在一实施例中,基站发送的目标DCI除了需要包括提前终止指示域之外,还需要包括与所述第一数据单元中成功解调的数据块所对应的混合自动重传请求HARQ进程号,便于终端根据目标DCI确定基站已经成功解调的数据块。
其中,可选地,在覆盖条件较好的第一覆盖增强模式下,例如MTC系统中的覆盖增强模式A下,基站可以将目标DCI中预先指定的5比特物理资源块的资源均设置为1,终端在接收到目标DCI之后,确定需要提前终止传输第一数据单元。且终端可以根据目标DCI中所包括的HARQ进程号,确定基站已经成功解调的数据块。
另外,在覆盖条件较差的第二覆盖增强模式下,例如MTC系统中的覆盖增强模式B下,基站可以将目标DCI中预先指定的4比特调制编码方式域对应的资源均设置为1,终端在接收到目标DCI之后,确定需要提前终止传输第一数据单元。且终端可以根据目标DCI中所包括的HARQ进程号,确定基站已经成功解调的数据块。
上述实施例中,基站发送的目标DCI中至少包括提前终止指示域和与所述第一数据单元中成功解调的数据块所对应的混合自动重传请求HARQ进程号,便于终端根据提前终止指示域来提前终止上传第一数据单元到基站,且便于终端根据目标DCI中携带的HARQ进程号,确定基站在所述第一数据单元中成功解调的数据块,有利于后续基站与终端之间的数据交互。
在一实施例中,为了在终端后续重复上传第二数据单元时,更好的匹配当前的信道状况,可选地,目标DCI中还可以包括第二目标次数;所述第二目标次数是所述终端重复上传所述第二数据单元的最大次数,且所述第二目标次数小于所述第一目标次数。
在上述实施例中,基站发送的目标DCI中还可以包括第二目标次数;所述第二目标次数是所述终端重复上传所述第二数据单元的最大次数,且所述第二目标次数小于所述第一目标次数。基站通过目标DCI对终端后续上传第二数据单元的重复上传次数进行调整,提高了后续第二数据单元的传输效率。
在一实施例中,参照9所示,图9是根据图7所示的实施例示出的另一种提前终止传输方法流程图,所述方法还可以包括:
在步骤407中,为所述终端配置所述第二目标次数;
本步骤中,基站可以采用以下方式中的任意一种为终端配置所述第二目标次数。
第一种方式,基站通过第一预设信令为所述终端配置备选次数集合,进一步地,基站通过目标DCI在备选次数集合中指定一个数值作为所述第二目标次数对应的数值。
在此种方式下,基站可以通过RRC信令为终端配置一个备选次数集合,例如备选次数集合为{6,16,24,32},第一目标次数为32,则基站可以通过目标DCI在上述备选次数集合中选取一个小于第一目标次数的数值作为第二目标次数对应的数值,例如选取24作为第二目标次数对应的数值。
第二种方式,基站通过第一预设信令为所述终端配置备选偏移量集合,通过所述目标DCI在所述备选偏移量集合中选取一个作为目标偏移量对应的数值,由所述终端根据所述第一目标次数和所述目标偏移量,计算得到所述第二目标次数。
此种方式下,基站可以通过RRC信令为终端先配置一个备选偏移量集合,例如{-4,-8,-12,-16},再通过目标DCI为终端在备选偏移量集合中选取一个作为目标偏移量,例如选取-8作为目标偏移量。终端可以计算第一目标次数和目标偏移量的和值,得到所述第二目标次数,例如计算得到的第二目标次数为32-8=24。
在步骤408中,接收所述终端按照所述第二目标次数开始重复上传的所述第二数据单元。
本步骤中,之前终端重复上传第一数据单元的总次数不能超过第一目标次数32,则现在终端重复上传第二数据单元的总次数不能超过第二目标次数24。
在上述实施例中,基站可以为终端配置备选次数集合,进而通过目标DCI在备选次数集合中指定一个数值作为所述第二目标次数对应的数值。或者,基站可以为终端配置备选偏移量集合,进而通过目标DCI在所述备选偏移量集合中选取一个作为目标偏移量对应的数值,由所述终端根据所述第一目标次数和所述目标偏移量,计算得到所述第二目标次数。通过上述过程,可以让基站根据当前信道状况,调整第二数据单元的重复上传次数,提高了传输效率,可用性高。
下面再从MTC系统中的终端侧来介绍上述第二种方案。
本公开实施例提供了另一种提前终止传输方法,可以用于机器类通信MTC系统中的终端。参照图10所示,图10是根据一示例性实施例示出的另一种提前终止传输方法流程图,可以包括以下步骤:
在步骤501中,重复上传第一数据单元到MTC系统中的基站,所述第一数据单元包括所述终端当前需要传输给所述基站进行解调的多个互不相同的数据块;
在步骤502中,如果在重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,接收到所述基站发送的目标下行控制信息DCI,则提前终止上传所述第一数据单元到所述基站;其中,所述第一目标次数是由所述基站为所述终端配置的重复上传所述第一数据单元的最大次数;
在步骤503中,提前终止上传所述第一数据单元之后,重复上传第二数据单元到所述基站;所述第二数据单元包括所述第一数据单元中除了所述基站已经成功解调的数据块之外的所有数据块。
上述实施例中,终端可以重复交替上传不同的数据块到基站,即重复上传第一数据单元到基站,基站如果在终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,确定成功解调了第一数据单元中预设数目的数据块,则基站会发送目标DCI到终端,终端可以根据目标DCI,停止重复上传第一数据单元到基站之后, 开始重复上传第二数据单元到基站。通过上述过程,实现了在终端重复交替上传不同的多个数据块的情况下,基站可以在成功解调终端重复交替上传的部分数据块时就发送目标DCI到终端,来提前终止终端上传第一数据单元的目的,有利于节省MTC系统终端的资源。
针对上述步骤501,终端当前需要基站解调的数据块包括4个互不相同的数据块TB1、TB2、TB3和TB4。则TB1、TB2、TB3和TB4组成了第一数据单元,终端重复上传第一数据单元到基站。
针对上述步骤502,假设基站为终端配置的第一目标次数为32。基站在接收第一数据单元的总次数未达到第一目标次数,即未达到32次之前,就成功解调了第一数据单元中预设数目的数据块,则基站会下发目标DCI到终端。
其中,基站可以将通信协议中预定义的所述基站需要在所述第一数据单元中成功解调的数据块的数目作为所述预设数目,或者由基站通过第一预设信令为所述终端配置所述预设数目。
针对上述步骤503,终端按照相关技术接收到目标DCI之后,如果处于当前覆盖条件较好的第一增强覆盖模式下,例如覆盖增强模式A下,终端可以查找DCI中预先指定的5比特物理资源块的资源所对应的数值是否为1,如果为1,确定该DCI为目标DCI,且需要根据提前终止指示域的指示提前终止传输第一传输单元到基站。
另外,终端按照相关技术接收到目标DCI之后,如果处于当前覆盖条件较差的第二增强覆盖模式下,例如覆盖增强模式B下,终端可以查找DCI中预先指定的4比特调制编码方式域对应的资源所对应的数值是否为1,如果为1,确定该DCI为目标DCI,且需要根据提前终止指示域的指示提前终止传输第一传输单元到基站。
终端在提前终止传输第一数据单元到基站之后,为了确保基站可以对其他未成功解调的数控块进行进一步解调,则终端可以继续重复上传第二数据单元到基站,其中所述第二数据单元包括所述第一数据单元中除了所述基站已经成功解调的数据块之外的所有数据块,例如图11所示。
上述实施例中,实现了在终端重复交替上传不同的多个数据块的情况下,基站可以在成功解调终端重复交替上传的部分数据块时就发送目标DCI到终端,来提前终止终端上传第一数据单元的目的,有利于节省MTC系统终端的资源。
在一实施例中,参照12所示,图12是根据图10所示的实施例示出的另一种提前终止传输方法流程图,所述方法还可以包括:
在步骤504中,确定所述基站为所述终端配置的第一目标时间单元的第一目标时间单元编号和第二目标时间单元的第二目标时间单元编号。
其中,所述第一目标时间单元满足第一目标条件,所述第二目标时间单元满足第二目标条件。
在本公开实施例中,涉及到的时间单元可以为子帧、时隙等。
其中,终端如何确定第一目标时间单元编号和第二目标时间单元编号的方式与基站侧确定第一目标时间单元编号和第二目标时间单元编号的方式相同,可以参照步骤404,在此不再赘述。
终端确定了第一目标时间单元编号和第二目标时间单元编号之后,则步骤502可以具体为:
在所述第一目标时间单元的下一个时间单元开始停止发送所述第一数据单元到所述基站。
例如第一目标时间单元编号为23,则终端可以在第24个时间单元开始停止发送第一数据单元到基站。
终端确定了第一目标时间单元编号和第二目标时间单元编号之后,则步骤503可以具体为:
在所述第二目标时间单元开始重复上传所述第二数据单元到所述基站。
例如第二目标时间单元编号为24,则终端可以在第24个时间单元开始重复上 传第二数据单元到基站。
上述实施例中,由基站为终端配置第一目标时间单元编号和第二目标时间单元编号,从而在基站侧和终端侧统一确定停止接收第一数据单元的时间点和开始接收第二数据单元的时间点,便于基站与终端之间进行数据交互,避免遗漏数据影响终端业务,且可以有效节省基站侧资源和终端资源。
在一实施例中,参照13所示,图13是根据图10所示的实施例示出的另一种提前终止传输方法流程图,所述方法还可以包括:
在步骤505中,确定所述基站为所述终端配置的重复的所述第二目标次数;所述第二目标次数是所述终端重复上传所述第二数据单元的最大次数,且所述第二目标次数小于所述第一目标次数;
本步骤中,基站可以通过第一预设信令,例如RRC信令先为终端配置一个备选次数集合,例如{6,16,24,32},进一步地,基站通过目标DCI在备选次数集合中选取一个作为第二目标次数对应的数值,例如选取24作为所述第二目标次数对应的数值。
或者基站可以通过第一预设信令,例如RRC信令先为终端配置一个备选偏移量集合,例如{-4,-8,-12,-16},再由基站通过目标DCI在备选偏移量集合中选取一个作为目标偏移量,例如选取-8作为目标偏移量。此时,终端可以计算第一目标次数和目标偏移量的和值,得到第二目标次数。例如第二目标次数为32-8=24。
终端在确定了第二目标次数之后,步骤503可以具体为:
按照所述第二目标次数开始重复上传第二数据单元到所述基站。
即终端开始重复上传第二数据单元之后,重复上传第二数据单元的总次数不能超过第二目标次数。
上述实施例中,基站通过目标DCI对终端后续上传第二数据单元的重复上传次数进行调整,终端按照目标DCI中指示的第二目标次数来重复上传第二数据单元,可以更合理的利用当前的信道情况,提高传输效率。
本公开实施例还提供了另一种提前终止传输方法。参照图14所示,图14是根据一示例性实施例示出的另一种提前终止传输方法流程图,可以包括以下步骤:
在步骤601中,MTC系统中的终端重复上传第一数据单元到MTC系统中的基站。
其中,所述第一数据单元包括所述终端当前需要传输给所述基站进行解调的多个互不相同的数据块。
在步骤602中,所述基站在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,确定是否成功解调所述第一数据单元中预设数目的数据块。
在步骤603中,所述基站在所述终端重复上传所述第一数据单元的总次数未达到第一目标次数之前,确定成功解调所述第一数据单元中预设数目的数据块,则发送目标DCI到所述终端。
其中,所述目标DCI中包括提前终止指示域、第一数据单元中成功解调的数据块所对应的混合自动重传请求HARQ进程号和第二目标次数。
在步骤604中,基站确定第一目标时间单元的第一目标时间单元编号和第二目标时间单元的第二目标时间单元编号。
在步骤605中,终端确定第一目标时间单元的第一目标时间单元编号和第二目标时间单元的第二目标时间单元编号。
步骤604和步骤605可以同步执行。
在步骤606中,基站在第一目标时间单元的下一个时间单元开始停止对所述第一数据单元的接收。
在步骤607中,终端在第一目标时间单元的下一个时间单元开始停止上次所述第一数据单元到基站。
在步骤608中,基站在第二目标时间单元开始接收终端重复上传的第二数据单 元。
其中,所述第二数据单元包括所述第一数据单元中除了所述基站已经成功解调的数据块之外的所有数据块。
在步骤609中,终端在第二目标时间单元开始,按照所述第二目标次数重复上传第二数据单元到基站。
步骤608和步骤609可以同步执行。
上述实施例中,当终端向基站交替上传多个不同的数据块时,即重复上传第一数据单元时,基站在终端重复上传所述第一数据单元的总次数未达到所述第一目标次数之前,成功解调第一数据单元中预设数目的数据块时就可以下发目标DCI到终端,来指示终端提前终止上传第一数据单元到基站。在终端重复交替上传不同的多个数据块的情况下,实现了提前终止传输的目的,有利于节省MTC系统终端的资源。
与前述应用功能实现方法实施例相对应,本公开还提供了应用功能实现装置、及相应的基站和终端的实施例。
参照图15,图15是根据一示例性实施例示出的一种提前终止传输装置框图,所述装置用于机器类通信MTC系统中的基站,所述装置包括:
