Description

混合自动重传请求反馈配置方法及装置和数据接收设备 技术领域
本公开涉及通信技术领域，尤其涉及一种混合自动重传请求(HARQ)反馈配置方法及装置、待重传数据的确定方法及装置、数据接收设备、数据发送设备和计算机可读存储介质。
背景技术
随着通信技术的发展，出现了第五代移动通信技术(5th Generation，简称5G)。5G目前的业务类型至少包括增强移动宽带(enhanced Mobile Broad Band，简称eMBB)、海量机器类通信(massive Machine Type Communication，简称mMTC)、超高可靠与低延迟的通信(Ultra Reliable Low Latency Communication，简称URLLC)等多种类型。这些业务同属数据业务，但对时延和可靠性的要求各不相同，例如URLLC业务用于车联网等需要低时延的领域，对及时性要求很高，建立业务时需要及时，甚至对之前业务具有抢占性。而mMTC业务则通常对时延并不敏感，可以间隔较长时间送达数据。实现对时延敏感业务有效传输的一种方式是改进混合自动重传请求(Hybrid Automatic Repeat reQuest，简称HARQ)的传输，例如，使得重传反馈更快更准确。第三代合作伙伴计划(3GPP)5G新空口(new radio，简称NR)将针对代码块组(Code Block Group，简称CBG)进行重传，而不是长期演进(Long Term Evolution，简称LTE)中的针对传输块(Transmission Block，简称TB)的重传，其中，CBG是TB中更小的数据单元单位。
对于多个载波的HARQ重传，需要将多个载波单元(Component Carrier，简称CC)的重传信息进行有效的编码聚合，以实现统一地将重传比特(bit)进行回传。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
而将来有可能出现不同的CC中1个TB的CBG数目并不相同的情况，对于这种情况，可以根据单个CC所包含的最大CBG数量与需要传输的数据总次数的乘积确定回传码本的长度，也可以将包含的CBG数目相同的CC合起来反馈一个码本(codebook)，以减少反馈bit的浪费，但是需要反馈多个HARQ codebook，维持很多个计数(counter)下行授予索引(Downlink Assignment Index，简称DAI)和总(total)DAI。但是无论采用哪种反馈方式，均不能适应复杂的情况。
图1是本申请一示例性实施例示出的一种HARQ反馈配置方法的流程图，该实施例从数据接收端进行描述，其中，数据接收端可以为基站，也可以为UE，如图1所示，该HARQ反馈配置方法包括：
在步骤S101中，根据载波聚合信息，为数据发送端配置HARQ码本切换信息。
其中，根据载波聚合信息，为数据发送端配置HARQ码本切换信息可以包括但不局限于以下任意一种或几种情形：
1)当聚合载波单元CC的总数小于预设阈值时，为数据发送端配置第一HARQ码本格式，当聚合CC的总数大于或等于预设阈值时，为数据发送端配置第二HARQ码本格式。
其中，第一HARQ码本格式由聚合CC中单个CC所包含的最大资源单位数量与聚合CC需要传输的数据总次数确定。第二HARQ码本格式由聚合CC中每个CC组内单个CC所包含的资源单位数量与对应CC组需要传输的数据总次数确定，其中，聚合CC将包含相同数量资源单位的CC划分为一组，该资源单位可以包括但不局限于CBG。
为了更清楚地描述第一HARQ码本格式和第二HARQ码本格式的区别，下面以8个 CC为例进行描述。其中，CC0包括4个CBG，CC1包括2个CBG，CC2包括1个CBG，CC3包括2个CBG，CC4包括3个CBG，CC5包括3个CBG，CC6包括2个CBG，CC7包括3个CBG。图2中的灰色块表示有数据传输的时隙(slot)，从图2中可以看出CC0～CC7需要传输的数据总次数为13次，单个CC所包含的最大CBG数量为4个，则第一码本格式包括一个码本，且码本总长度为13*4＝52bit。为了描述第二码本格式，需要对CC进行分组，例如，可以将图2中的CC划分为图3所示的多个CC组，从图3可以看出，第一个CC组中的CC2包含1个CBG，CC2需要传输的数据总次数为2次，第二个CC组中的CC包含2个CBG，第二个CC组需要传输的数据总次数为5次，第三个CC组中的CC包含3个CBG，第三个CC组需要传输的数据总次数为4次，第四个CC组中的CC0包含4个CBG，CC0需要传输的数据总次数为2次，第二码本格式包括4个码本且码本总长度为1*2+2*5+3*4+4*2＝36bit。
该切换方式可以很好地适应聚合CC总数的变化情况，且可减少反馈开销。
2)当聚合CC中所有CC包含的资源单位数量均相同时，为数据发送端配置第一HARQ码本格式，当聚合CC中CC包含的资源单位数量不同时，为数据发送端配置第二HARQ码本格式。
该切换方式可以很好地适应聚合CC的资源单位数量分布变化情况，且可减少反馈开销。
3)当聚合CC所承载的业务不包括预设业务时，为数据发送端配置第一HARQ码本格式，当聚合CC所承载的业务包括预设业务时，为数据发送端配置第二HARQ码本格式。
其中，预设业务可以包括但不局限于URLLC业务。
该切换方式可以很好地适应业务需求变化情况，且可减少反馈开销。
4)当聚合CC所承载的业务传输量大于或等于预设传输量时，为数据发送端配置第一HARQ码本格式，当聚合CC所承载的业务传输量小于预设传输量时，为数据发送端配置第二HARQ码本格式。
该切换方式可以很好地适应传输需求变化情况，且可减少反馈开销。
5)当聚合CC所承载的业务传输分散在包含不同资源单位数量的CC时，为数据发送端配置第一HARQ码本格式，当聚合CC所承载的业务传输集中在包含相同资源单位数量的CC时，为数据发送端配置第二HARQ码本格式。
该切换方式可以很好地适应业务传输分布变化情况，且可减少反馈开销。
在步骤S102中，向数据发送端发送HARQ码本切换信息。
当数据接收端为基站时，数据发送端为UE，当数据接收端为UE时，数据发送端为基站。在该实施例中，数据接收端配置HARQ码本切换信息后，可以向数据发送端发送HARQ码本切换信息，以使数据发送端根据接收的HARQ码本切换信息确定待重传数据的资源单位信息。
上述实施例，通过根据载波聚合信息，为数据发送端配置HARQ码本切换信息，以适应复杂情况，并向数据发送端发送HARQ码本切换信息，使得数据发送端可以据此确定待重传数据的资源单位信息。

在步骤S401中，根据载波聚合信息，为数据发送端配置HARQ码本切换信息。
在步骤S402中，向数据发送端发送HARQ码本切换信息和HARQ码本解释信息，HARQ码本解释信息是指与每个HARQ码本对应的每个反馈比特表示单个资源单位的HARQ反馈信息或多个资源单位的HARQ反馈信息。
HARQ码本解释信息可以对相同codebook反馈信息有不同的解释，例如同样是8bit的反馈信息，可以解释为8个资源单元例如CBG的HARQ反馈信息，也可以解释为16个资源单位例如CBG中两两与或计算后的HARQ反馈信息。当业务传输量较大时，每个反馈bit表示多于2个资源单位例如CBG的与或信息，可以节省反馈开销。
其中，HARQ码本切换信息和HARQ码本解释信息可以通过同一信息表示，即HARQ码本切换信息和HARQ码本解释信息为同一信息。另外，HARQ码本切换信息和HARQ码本解释信息也可以为两个信息。

在步骤S602中，保存HARQ码本切换信息和HARQ码本解释信息，以用于根据HARQ码本切换信息和HARQ码本解释信息对数据接收端反馈的HARQ码本进行处理，以确定待重传数据的资源单位信息。
其中，HARQ码本解释信息是指与每个码本对应的每个反馈比特表示单个资源单位的HARQ反馈信息或多个资源单位的HARQ反馈信息。
上述HARQ码本切换信息和HARQ码本解释信息可以通过同一信息表示，即HARQ码本切换信息和HARQ码本解释信息为同一信息。另外，HARQ码本切换信息和HARQ码本解释信息也可以为两个信息。

HARQ码本解释信息可以对相同codebook反馈信息有不同的解释，例如同样是8bit的反馈信息，可以解释为8个资源单元例如CBG的HARQ反馈信息，也可以解释为16个资 源单位例如CBG中两两与或计算后的HARQ反馈信息。当业务传输量较大时，每个反馈bit表示多于2个资源单位例如CBG的与或信息，可以节省反馈开销。
其中，HARQ码本切换信息和HARQ码本解释信息可以通过同一信息表示，即HARQ码本切换信息和HARQ码本解释信息为同一信息。另外，HARQ码本切换信息和HARQ码本解释信息也可以为两个信息。
