(Acknowledgement, abbreviated as ACK), if the decoding error is fed back a Negative Acknowledgement (NACK), the sender retransmits the corresponding data block.

Description

混合自动重传请求信息的发送、接收方法及装置 技术领域
本公开涉及通信领域，具体而言，涉及一种混合自动重传请求(Hybrid Automatic Repeat-reQuest,简称HARQ)信息的发送、接收方法及装置。
背景技术
HARQ是通信系统中进行差错控制的一种传输机制。具体地，发送端发送数据块后，接收端解码后通过循环冗余校验(Cyclic Redundancy Check，简称CRC)校验信息来判断数据包是否解调正确，如果解码正确则向发送端反馈确认指令(Acknowledgement，简称ACK)，如果解码错误则反馈非确认指令(Negative Acknowledgement，简称NACK)，发送端则重传对应的数据块。
长期演进(LTE，Long TermEvolution)及高级长期研究(LTE-A，LTE-Advanced)系统中结合前向纠错(Forward Error Correction,简称FEC)使用混合ARQ(Hybrid ARQ,HARQ)，具体的，对于频分双工(Frequency Division Duplexing，简称FDD)采用8个进程的等停式HARQ，对于时分双工(Time Division Duplexing，简称TDD)进程数则取决于上下行配比。进一步，HARQ协议中根据时域的灵活性可以分为同步或异步HARQ，而根据频域上的灵活性可以分为自适应或非自适应HARQ。
在现有LTE/LTE-A协议中，对于下行传输，采用的是异步HARQ，对于上行传输，采用的是同步HARQ。对于FDD系统，终端在子帧n接收到的物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)将在子帧n+4反馈确认/不确认(ACK/NACK)，如果反馈的是NACK重传将会出现在随后的任意子帧，通常在接收到NACK后的第四个及以后的子帧重传；基站在子帧n接收到的物理下行共享信道(Physical Uplink Shared Channel，简称PUSCH)将在子帧n+4反馈ACK/NACK，如果反馈的是NACK重传将会出现在n+8子帧。对于TDD系统，具体的定时位 置和重传位置取决于上下行配比。
在3GPP后续演进如第五代移动通信系统(5G)将支持如工业自动化、远程控制、智能电网等超低时延业务。为了支持超低时延，一种是将现有的传输时间间隔(TTI，Transmission Time Interval)降低，如将现有子帧内14个OFDM符号降低为1～7个。一种是降低1ms或短TTI操作的处理时延。
其中，为降低处理时延，一种途径是实现快速反馈，降低从初传到重传的时间。然而现有协议中的重传时延至少为8ms，重传时延大。进一步，从HARQ分析中可知，重传只出现在反馈为NACK的情况，因此有必要进一步加快NACK的快速重传。然而现有协议中ACK和NACK反馈定时相同，不能实现NACK相对于ACK更快地反馈。
发明内容
本公开实施例提供了一种HARQ信息的发送、接收方法及装置，以至少解决相关技术中NACK不能够相对ACK更快地反馈的的问题。
根据本公开的一个实施例，提供了一种HARQ信息的发送方法，包括：第一设备在第一设备的传输时间单元n上接收第二设备发送的数据；所述第一设备根据预定义HARQ定时集合选择要发送HARQ信息的传输时间单元位置，所述预定义集合中包括N个HARQ定时位置，N为等于或大于2的正整数；所述第一设备在选择的传输时间单元位置上发送针对所述数据的HARQ信息。
根据本公开的一个实施例，提供了一种HARQ信息的接收方法，包括：第二设备在传输时间单元n上向第一设备发送数据；所述第二设备根据预定义HARQ定时集合选择要接收的HARQ的传输时间单元位置，所述预定义集合中包括N个HARQ定时位置，N为等于或大于2的正整数；所述第二设备在选择的传输时间单元位置上接收针对所述数据的HARQ信息。
根据本公开实施例的又一实施例，提供了一种HARQ信息的发送装 置，应用于第一设备，所述装置包括：接收模块，设置为在传输时间单元n上接收第二设备发送的数据；选择模块，设置为从预定义HARQ定时集合选择要发送HARQ信息的传输时间单元位置，所述预定义集合中包括N个HARQ定时位置，N为等于或大于2的正整数。
根据本公开实施例的再一实施例，提供了一种HARQ信息的接收装置，应用于第二设备，所述装置包括：发送模块，设置为在传输时间单元n上向第一设备发送数据，其中，所述传输时间单元为用于传输信息的时间单元；选择模块，设置为从预定义HARQ定时集合选择要接收HARQ的传输时间单元位置，所述预定义集合中包括N个HARQ定时位置，N为等于或大于2的正整数；接收模块，设置为在选择的传输时间单元位置上接收所述数据的混合自动重传请求。
根据本公开的又一个实施例，还提供了一种存储介质。该存储介质设置为存储用于执行以下步骤的程序代码：第一设备在第一设备的传输时间单元n上接收第二设备发送的数据；所述第一设备根据预定义HARQ定时集合选择要发送HARQ信息的传输时间单元位置，所述预定义集合中包括N个HARQ定时位置，N为等于或大于2的正整数；所述第一设备在选择的传输时间单元位置上发送针对所述数据的HARQ信息。
根据本公开的又一个实施例，还提供了另一种存储介质。该存储介质设置为存储用于执行以下步骤的程序代码：第二设备在传输时间单元n上向第一设备发送数据；所述第二设备根据预定义HARQ定时集合选择要接收的HARQ的传输时间单元位置，所述预定义集合中包括N个HARQ定时位置，N为等于或大于2的正整数；所述第二设备在选择的传输时间单元位置上接收针对所述数据的HARQ信息。
通过本公开，由于重新定义了混合自动重传请求的反馈时机，即以预定义集合中的HARQ定时位置作为混合自动重传请求的定时发送位置，从而可以实现NACK的快速反馈，实现了ACK和NACK的分类定时，进而实现NACK的快速反馈以降低重传时延，因此，可以解决相关技术中 NACK不能够相对ACK更快地反馈的问题。

为了更好地理解上述实施例，以下结合实施例5-13详细说明
实施例5
图5为下行HARQ在两个定时位置发送且两处均反馈NACK的示意图。图5中基站在传输时间单元n上发送初传数据，终端在对应的传输时 间单元上接收到数据后分别同时根据不同的规则对接收数据进行判决。例如，为实现在第一个定时位置的快速判决，终端根据传输时间单元n时刻的信道状态，得到量化的信道质量值，与预定义的信道质量值门限比较得到。进一步，信道质量门限可以根据仿真统计获得，使得低于此门限时有较大概率的出错，比如90％的BLER。图中，终端根据快速判决和实际解调数据判决得到的结果均为NACK。则终端分别在传输时间单元n+2和n+4上分别进行NACK反馈。相应的，基站在传输时间单元n+2上接收到NACK反馈后会调度在传输时间单元n+6上的重传，基站在传输时间单元n+4上接收到NACK反馈后并不会触发重传。此处对应地k1＝2,k2＝4,m1＝4。采用此实施例可以在错误接收数据时加快重传的发送，进而降低时延。本实施例对于上行HARQ定时同样适用。
实施例6
图6为下行HARQ在两个定时位置发送且第一个位置处快速判决为ACK的示意图。图6中基站在传输时间单元n上发送初传数据，终端在对应的传输时间单元上接收到数据后分别同时根据不同的预定规则对接收数据进行判决。例如，为实现在第一个定时位置的快速判决，终端根据传输时间单元n时刻及前一个时刻的信道状态，联合得到量化的信道质量值，与预定义的信道质量值门限比较得到。图中，终端根据快速判决得到的结果为ACK，对应的，终端在传输时间单元n+2不做反馈。传输时间单元n+4根据数据解码获得的反馈结果，如果正确反馈ACK，如果错误反馈NACK。如果反馈的是NACK，基站在收到NACK后会调度在传输时间单元n+8上的重传。如果反馈的是ACK，基站在收到ACK后不会触发重传。此处对应地k2＝4,m2＝4。采用此实施例方法，当在第一个定时位置判断为ACK且不反馈时，可以节省反馈资源，并不影响在第二个定时位置的反馈操作。本实施例对于上行HARQ定时同样适用。
实施例7
图7为上行HARQ在两个定时位置发送且两处均反馈NACK的示意图。图7中终端在传输时间单元n上发送初传数据，基站在对应的传输时间单元上接收到数据后分别同时根据不同的规则对接收数据进行判决。例如，为实现在第一个定时位置(即HARQ定时位置)的快速判决，基站只解码部分数据根据初步解码结果进行判决。图7中，终端根据快速判决和实际解调数据判决得到的结果均为NACK。基站分别在传输时间单元n+2和n+3上进行NACK反馈，相应的，终端在传输时间单元n+2上接收到NACK反馈后会调度在传输时间单元n+5上的重传。终端在传输时间单元n+3上接收到NACK反馈后会调度在传输时间单元n+6上的重传。此处对应地k1＝2,k2＝3,m1＝3,m2＝3。采用此实施例方法，可以连续触发多次重传，在恶劣信道环境下能够在增加传输可靠性且不引入更多时延。本实施例对于下行HARQ定时同样适用。
实施例8
图8为上行HARQ在两个定时位置发送且两处均反馈NACK的示意图。基站在对应的传输时间单元上接收到数据后分别同时根据不同的规则对接收数据进行判决。图8中，基站根据快速判决和实际解调数据判决得到的结果均为NACK。此时，基站只在第一个定时位置处即传输时间单元n+2上进行NACK反馈，相应的，终端在传输时间单元n+2上接收到NACK反馈后会调度在传输时间单元n+5上的重传。此时，基站在第二个定时位置n+k2处并不进行反馈。对应地k1＝2,m1＝3。此时，可以在恶劣信道状态下减少重传时延且降低了反馈资源的开销。
进一步，如果基站根据快速判决得到的结果是ACK，基站在传输时间单元n+k1处不反馈，优先的，在传输时间单元n+k2处，基站根据实际解调数据得到的判决正确时则反馈ACK，错误时则反馈NACK。相应地，终端在传输时间单元n+k1时不做相应处理，而是根据在n+k2处的反馈决 定是否重传。
本实施例对于下行HARQ定时同样适用。
实施例9
图9为下行HARQ在两个定时位置发送且第一个位置处快速判决为NACK、第二个位置处判决为ACK的示意图。图9中基站在传输时间单元n上发送初传数据，所述初传数据含有2个数据块，终端在对应的传输时间单元上接收到数据后分别同时根据不同的预定规则对接收数据进行判决。图9中，终端根据快速判决发现存在一个数据块接收错误，而根据实际解调判决得到两个数据块均接收正确。对应地，终端分别在传输时间单元n+2和n+4处进行捆绑反馈，即在传输时间单元n+2处反馈1比特NACK，在传输时间单元n+4反馈1比特ACK。当基站在传输时间单元n+2收到NACK反馈时会准备重传数据的发送，但当在传输时间间隔n+4时收到了ACK反馈，此时基站取消重传数据的发送，即不在传输时间间隔n+6发送重传数据。采用此实施例方法，当出现所描述情况时可以避免由于第一个定时位置处误判而导致的重传，进而避免了不必要的资源浪费。此处对应地k1＝2,k2＝4。本实施例对于上行HARQ定时同样适用。
实施例10
图10为上行HARQ在两个定时位置(即HARQ定时位置)发送且第一个位置(即第一个HARQ定时位置)处快速判决为NACK、第二个位置处判决为ACK的示意图。图10中终端在传输时间单元n上发送初传数据，所述初传数据含有2个数据块，基站在对应的传输时间单元上接收到数据后分别同时根据不同的预定规则对接收数据进行判决。图10中，基站根据快速判决发现存在一个数据块接收错误，而根据实际解调判决得到两个数据块均接收正确。对应地，基站分别在传输时间单元n+2处进行捆 绑反馈，即在传输时间单元n+2处反馈1比特NACK，在传输时间单元n+4处对两个数据块均进行反馈，此处为两比特ACK。当终端在传输时间单元n+2收到NACK反馈时会准备重传数据的发送，即使当终端在传输时间间隔n+4时收到了两比特ACK反馈，此时终端也不会取消重传数据的发送，即终端仍然在传输时间单元n+5发送重传数据。此实施例是描述了终端处理能力不够的情况下，即在传输时间单元n+5处还没能完成n+3反馈的情况。本实施例对于下行HARQ定时同样适用。
实施例11
图11为下行HARQ在两个定时位置(即HARQ定时位置)发送且第一个位置(即第一个HARQ定时位置)处快速判决为ACK、第二个位置处判决为NACK的示意图。图11中基站在传输时间单元n上发送初传数据，所述初传数据含有1个数据块，终端在对应的传输时间单元上接收到数据后分别同时根据不同的预定规则对接收数据进行判决。而且遵循如下发送规则，在传输时间单元n+2处如果判决正确则不反馈，判决错误则反馈NACK，在传输时间单元n+4处如果判决错误则不反馈，判决正确则反馈ACK，在图例中，终端根据快速判决发现数据接收正确，而根据实际解调判决数据接收错误。对应地，终端在传输时间单元n+2和n+4处均不进行任何反馈。对于这种情况，基站将在n+4后准备重传数据的发送，图例中在传输时间单元n+8处进行重传。此处对应地k1＝2,k2＝4，m2＝4。采用本实施例方法，在所述场景下，即使基站没有检测到任何反馈仍然可以重发，在不产生歧义的情况下节省了开销。本实施例对于上行HARQ定时同样适用。
实施例12
图12为下行HARQ在两个定时位置(即HARQ定时位置)发送且第一个位置(即第一个HARQ定时位置)处为自包含反馈的示意图。图12 中基站在传输时间单元n上发送初传数据，传输数据只占据传输时间单元的前半部分。终端在对应的传输时间单元上接收到数据后分别同时根据两种不同的判决规则对接收数据进行判决。图中，终端根据第一级和第二级判决规则得到的判决结果均为NACK，图12中终端分别在传输时间单元n和n+1上进行NACK反馈。相应的，基站在传输时间单元n上接收到NACK反馈后会调度在传输时间单元n+1上的重传，基站在传输时间单元n+1上接收到NACK反馈后并不会触发重传。采用本实施例方法，可以更容易实现自包含反馈，可以降低重传时延。此处对应地k1＝0,k2＝1,m1＝1。本实施例对于上行HARQ定时同样适用。
实施例13
图13为上行HARQ在两个定时位置发送且传输单元内同时含有上下行的示意图。图13中终端在传输时间单元n上发送初传数据，传输数据只占据传输时间单元的前半部分。基站在对应的传输时间单元上接收到数据后分别同时根据两种不同的判决规则对接收数据进行判决。图13中，终端根据第一级判决规则得到的判决结果为NACK，根据第二级判决规则得到的判决结果为ACK。图13中基站在传输时间单元n+1上进行NACK反馈，在传输时间单元n+2上进行ACK反馈。相应的，终端在传输时间单元n+1上接收到NACK反馈后会调度在传输时间单元n+2上的重传，终端在传输时间单元n+2上接收到ACK反馈后并不能取消重传。此处对应地k1＝1,k2＝2,m1＝1。进一步，如果在第一个定时位置处判为ACK时，在第一个定时位置不反馈，而在第二个定时位置处同样判决为ACK时，在第一个定时位置反馈ACK。如果在第一个定时位置除判决为ACK且在第一个定时位置不反馈，而且在第二个定时位置处判决为ACK也不反馈，则基站并不能区分到底是因为UL调度位解调错误导致没有任何反馈还是因为均解调正确而导致的没有任何反馈，进而导致可能的数据丢包。本实 施例对于上行HARQ定时同样适用。
实施例14
图14为下行HARQ在定义的两个定时位置的一个发送反馈的示意图。图14中基站在传输时间单元n上发送初传数据，所述初传数据含有1个数据块。图中，当所发送的数据块大小小于预定的一个门限时，如小于现有LTE协议中数据块最大值的一半时，或者UE处理能力较强时，终端能快速的解码判断是否接收正确，则终端在传输时间单元n+2上进行ACK/NACK反馈，如果解码正确反馈ACK，否则反馈NACK。如果所发送的数据块大小大于预定的一个门限时，或者UE处理能力较弱时，终端不能快速的解码判断，则终端在传输时间单元n+4上进行ACK/NACK反馈，如果解码正确反馈ACK，否则反馈NACK。本实施例对于上行HARQ定时同样适用。

工业实用性
通过本发明上述实施例提供的技术方案，由于重新定义了混合自动重传请求的反馈时机，即以预定义集合中的HARQ定时位置作为混合自动重传请求的定时发送位置，从而可以实现NACK的快速反馈，实现了ACK和NACK的分类定时，进而实现NACK的快速反馈以降低重传时延，因 此，可以解决相关技术中NACK不能够相对ACK更快地反馈的问题。
