Description

HARQ进程的配置方法、装置及设备 技术领域
本发明实施例涉及通信技术领域，特别涉及一种混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程的配置方法、装置及设备。
背景技术
HARQ是一种将前向纠错码(Forward Error Correction，FEC)和自动重传请求(Automatic Repeat reQuest，ARQ)相结合而形成的技术。采用HARQ技术，接收方在对接收到的数据解码失败的情况下，并不丢弃该接收到的数据，而是保存该接收到的数据，并要求发送方重传数据，接收方将重传的数据和先前接收到的数据进行合并后再解码。通过上述方式能够存在一定的分集增益，减少了重传次数，进而减少了数据传输时延。
长期演进(Long Term Evolution，LTE)系统中的数据传输采用HARQ技术。终端中的HARQ进程数由网络侧配置。HARQ进程数是指并发的HARQ进程的数量。一个HARQ进程是指一次完整的数据传输过程。LTE系统中的HARQ进程配置方案如下：网络侧为终端支持的载波对应配置固定的HARQ进程数，例如该固定的HARQ进程数为8。
以LTE系统中载波聚合(Carrier Aggregation，CA)场景为例，网络侧配置HARQ进程数的相关方法如下：网络侧为终端聚合的每一个载波对应配置一个独立的HARQ实体(entity)，也即终端聚合的每一个载波具有固定的HARQ进程数以及独立的HARQ调度。采用上述设计主要是考虑到在LTE系统中，聚合的各个载波具有相同的参数集(numerology)，也即具有相同的传输时间间隔(Transmission Time Interval，TTI)，在每个载波上进行HARQ操作时，HARQ可以具有相同的往返时延(Round Trip Time，RTT)。因此，终端聚合的每一个载波对应的HARQ参数是一致的，例如网络侧为终端聚合的每一个载波对应配置一个包含8个HARQ进程的HARQ实体。
现有技术中提供的HARQ进程配置方案，网络侧为终端支持的载波对应配置固定的HARQ进程数，存在HARQ进程的配置和调度的灵活度较低的问题。
发明内容
为了解决现有技术中HARQ进程的配置和调度的灵活度较低的问题，本发明实施例提供了一种HARQ进程的配置方法、装置及设备。所述技术方案如下：

当所述终端当前支持的载波发生变化时，调整为所述终端当前支持的载波分配的HARQ进程数。
可选地，所述调整为所述终端当前支持的载波分配的HARQ进程数之后，还包括：
向所述终端发送下行控制信息(Downlink Control Information，DCI)，所述DCI中携带HARQ配置信息，所述HARQ配置信息用于指示为所述终端当前支持的载波分配的HARQ进程数。
另一方面，本发明实施例提供一种接入网设备，该接入网设备具有实现上述方法示例的功能。所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的模块。
在一个可能的设计中，接入网设备的结构中包括处理器、发射器和接收器，所述处理器被配置为支持接入网设备执行上述方法中相应的功能。所述发射器和接收器用于支持接入网设备与终端之间的通信。进一步的，接入网设备还可以包括存储器，所述存储器用于与处理器耦合，其保存接入网设备必要的程序指令和数据。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
本发明实施例描述的网络架构以及业务场景是为了更加清楚地说明本发明实施例的技术方案，并不构成对本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本发明一个实施例提供的应用场景的示意图。该应用场景包括：接入网设备110和至少一个终端120。
如图1所示，终端120的数量通常为多个，该多个终端120位于接入网设备110所管理的小区之内。接入网设备110与终端120之间通过某种空口技术互相通信，例如可以通过蜂窝技术相互通信。本发明实施例描述的技术方案可以适用于LTE系统，也可以适用于LTE系统后续的演进系统，如LTE-A(LTE-Advanced)系统、第五代(5th Generation，5G)系统等。
本发明实施例中，名词“网络”和“系统”经常交替使用，但本领域技术人员可以理解其含义。本发明实施例所涉及到的终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。本发明实施例所涉及到的接入网设备是一种部署在无线接入网中用以为终端提供无线通信功能的装置，该接入网设备通常称为基站(Base Station，BS)。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为演进的节点B(evolved NodeB，eNB或eNodeB)。为方便描述，本发明实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
随着通信系统的发展和演进，通信系统需要支持多组不同的基础参数集(numerology)，不同的基础参数集可以在同一个载波或者不同的载波上支持。每一组基础参数集包括一组时频资源配置参数，不同的基础参数集对应的时频资源配置参数有所不同。一般来说，不同的基础参数集可采用不同的子载波间隔进行区分，例如不同的基础参数集对应的子载波间隔分别为15kHz、30kHz、60kHz、120kHz等等。比如，可以把对应15kHz的基础参数集作为参考基础参数集，在时域上，1ms子帧(subframe)包括两个时隙(slot)，每个时隙包含的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数量为7个或者14个(有待相关标准组织进一步讨论确定)；在频域上，一个资源块(Resource Block，RB)包含12个子载波。其它的基础参数集对应的子载波间隔可取值为15kHz×2n(n为非负整数)，在时域上，一个子帧包括的时隙数量为参考基础参数集对应的时隙数量的2n倍，在频域上，一个资源块仍然包含12个子载波。比如当n＝1时，可算出基础参数集对应的子载波间隔为30kHz，其一个子帧包括的时隙数量为4。
对于同一个载波复用多组不同的基础参数集的情况，相应的复用方式可以是时分复用(Time Division Multiplexing，TDM)方式或频分复用(Frequency Division Multiplexing，FDM)方式。其中，时分复用方式是指不同的基础参数集在时域上进行复用，也即不同的时段内使用不同的基础参数集。频分复用方式是指不同的基础参数集在频域上进行复用，也即不同的频段内使用不同的基 础参数集。
在本发明实施例中，网络侧为每一个终端对应配置一个独立的HARQ实体，该HARQ实体中包含n个HARQ进程，n为正整数。在载波聚合场景下，终端聚合的各个载波能够共享上述n个HARQ进程，且网络侧能够为终端聚合的各个载波动态调整分配的HARQ进程数，从而提高HARQ进程配置和调度的灵活度。在非载波聚合场景下，终端所支持的一个载波可以复用多组不同的基础参数集，该多组不同的基础参数集能够共享上述n个HARQ进程，当该载波支持的基础参数集发生变化时，网络侧能够为该载波动态调整分配的HARQ进程数，从而提高HARQ进程配置和调度的灵活度。
下面将基于上面所述的本发明实施例涉及的共性方面，对本发明实施例进一步详细说明。
请参考图2，其示出了本发明一个实施例提供的HARQ进程的配置方法的流程图。该方法可以包括如下几个步骤：
步骤201，为终端配置HARQ进程数n，n为正整数。
接入网设备为终端配置HARQ进程数。在本实施例中，为终端配置的HARQ进程数以n表示。接入网设备为终端配置一个HARQ实体，该HARQ实体中包含n个HARQ进程。在载波聚合场景下，终端聚合的各个载波能够共享上述n个HARQ进程。在非载波聚合场景下，终端所支持的一个载波可以复用多组不同的基础参数集，该多组不同的基础参数集能够共享上述n个HARQ进程。
上述为终端配置的HARQ实体中包含的HARQ进程可称为公共HARQ进程。对于载波聚合场景，公共HARQ进程是指供终端聚合的各个载波共用的HARQ进程。对于非载波聚合场景，公共HARQ进程是指供载波所支持的多组不同的基础参数集共用的HARQ进程。相应地，接入网设备为终端配置公共HARQ进程数，公共HARQ进程数是指公共HARQ进程的数量，例如以n表示。
可选地，接入网设备在与终端建立无线资源控制(Radio Resource Control，RRC)连接的过程中或者在建立RRC连接之后，为终端配置HARQ进程数。
可选地，本步骤包括如下几个子步骤：
1、获取终端的特征信息；
2、根据终端的特征信息，为终端配置HARQ进程数n。
终端的特征信息是指用于指示终端的特征的信息。示例性地，终端的特征信息包括以下至少一种：终端的HARQ缓存容量、终端的数据处理能力、终端聚合的各个载波的数量、终端聚合的各个载波的特征、终端所请求的主要业务类型。
可选地，接入网设备在与终端建立RRC连接的过程中或者在建立RRC连接之后，获取终端的特征信息。终端的特征信息可以由终端主动上报给接入网设备，也可以由接入网设备向终端发出指示后进行上报，或者由接入网设备根据通信系统的配置信息自行获取。
在一个示例中，以终端的特征信息为终端的HARQ缓存容量为例。终端的HARQ缓存容量是指终端的HARQ缓冲器对应的最大缓存容量。接入网设备根据终端的HARQ缓存容量和每个HARQ进程所需的缓存容量，确定为终端配置的HARQ进程数n。例如，终端的HARQ缓存容量为M(bits)，每个HARQ进程所需的缓存容量为N(bits)，则接入网设备为终端配置的HARQ进程数n可以为[M/N]；其中，符号“[]”表示向下取整。上述示例仅以每个HARQ进程所需的缓存容量相同为例，在实际情况中，每个HARQ进程所需的缓存容量也有可能不同。
在另一个示例中，以终端的特征信息为终端的数据处理能力为例。终端的数据处理能力是指终端接收到接入网设备发送的下行数据至终端向接入网设备反馈接收成功或失败响应的最小处理时间。接入网设备根据终端的数据处理能力和接入网设备的负载状态，确定为终端配置的HARQ进程数n。例如，根据终端的数据处理能力所确定的最小处理时间为a(ms)，根据接入网设备的负载状态确定的重传处理时间为b(ms)，接入网设备根据上述最小处理时间a和重传处理时间b确定为终端配置的HARQ进程数n。示例性地，为终端配置的HARQ进程数n＝(a+b)/TTI，TTI表示终端聚合的载波对应的TTI。
在又一个示例中，以终端的特征信息包括终端聚合的各个载波的数量和终端聚合的各个载波的特征为例。对于终端聚合的每一个载波，接入网设备根据该载波的特征确定为该载波对应配置的HARQ进程数，将为各个载波对应配置的HARQ进程数相加得到为终端配置的HARQ进程数n。其中，载波的特征包括以下至少一种：载波对应的TTI、载波所承载的业务类型。例如，终端聚合的载波数量为2，其中一个载波对应的TTI为0.25ms，接入网设备为该载 波对应配置的HARQ进程数为3，另一个载波对应的TTI为1ms，接入网设备为该载波对应配置的HARQ进程数为8，则接入网设备为终端配置的HARQ进程数为11。
在又一个示例中，以终端的特征信息包括终端所请求的主要业务类型为例。示例性地，业务类型包括增强型移动宽带(enhanced Mobile Broadband，eMBB)业务、大规模机器通信(massive Machine-type Communication，mMTC)业务、高可靠低时延通信(Ultra-relaible and Low Latency Communication，URLLC)业务等。当终端所请求的业务类型仅为一种时，该种业务类型即为终端所请求的主要业务类型；当终端所请求的业务类型为多种时，该多种业务类型中业务量最大的业务类型作为终端所请求的主要业务类型。例如，如果终端所请求的主要业务类型为时延敏感型业务(例如URLLC业务)，则接入网设备为终端配置较少的HARQ进程数；如果终端所请求的主要业务类型为时延容忍型业务(例如eMBB业务)，则接入网设备为终端配置较多的HARQ进程数。在实际应用中，接入网设备中可预存第一对应关系，该第一对应关系包括不同的业务类型和不同的HARQ进程数之间的对应关系，接入网设备查询上述第一对应关系确定为终端配置的HARQ进程数。
上文介绍了接入网设备根据终端的特征信息，为终端配置HARQ进程数n。在其它可能的实施例中，接入网设备中可预定义(Pre-determined)至少一个候选HARQ进程数。例如，接入网设备中配置候选HARQ进程数集合，该集合中包括6、8、10、12等若干个候选HARQ进程数。接入网设备从预定义的至少一个候选HARQ进程数(也即上述候选HARQ进程数集合)中，选择一个候选HARQ进程数配置给终端。
另外，接入网设备可通过DCI向终端发送为终端配置HARQ进程数n，也可以通过高层信令向终端发送为终端配置HARQ进程数n。
步骤202，将n个HARQ进程中的m个HARQ进程分配给终端当前支持的载波，其中，n≥m≥1，n、m均为正整数。
对于载波聚合场景，终端当前支持的载波包括该终端当前聚合的多个载波。接入网设备在为终端配置HARQ进程数之后，为终端聚合的各个载波初始化配置相应的HARQ进程数。接入网设备将n个HARQ进程中的m个HARQ进程分配给终端聚合的各个载波。也即，终端聚合的各个载波被分配的HARQ进程数之和为m。并且，终端聚合的各个载波中，存在至少两个载波被分配的 HARQ进程数相同或不同。例如，接入网设备为终端配置的HARQ进程数为20，终端聚合的载波数量为3，接入网设备为该3个载波分配的HARQ进程数分别为3、8、8。
可选地，在为终端聚合的各个载波初始化分配HARQ进程时，每一个载波被分配至少一个HARQ进程。
可选地，对于载波聚合场景，步骤202包括如下几个子步骤：
1、获取终端聚合的各个载波的特征信息；
2、根据终端聚合的各个载波的特征信息，将n个HARQ进程中的m个HARQ进程分配给终端聚合的各个载波。
载波的特征信息是指用于指示载波的特征的信息。示例性地，载波的特征信息包括以下至少一种：载波所采用的基础参数集、载波所承载的主要业务类型、载波所在的频带。终端聚合的各个载波的特征信息可以由终端主动上报给接入网设备，也可以由接入网设备向终端发出指示后进行上报，或者由接入网设备根据通信系统的配置信息自行获取。
在一个示例中，以载波的特征信息为载波所采用的基础参数集为例。载波所采用的基础参数集中包括TTI、子载波间隔、每个TTI中包含的符号数量等参数。以TTI为例，对于终端聚合的每一个载波，接入网设备根据该载波对应的TTI，从上述n个HARQ进程中选择至少一个HARQ进程分配给该载波。其中，为载波分配的HARQ进程数与载波对应的TTI呈正相关关系。也即，载波对应的TTI越长，为载波分配的HARQ进程数越多；载波对应的TTI越短，为载波分配的HARQ进程数越少。在实际应用中，接入网设备中可预存第二对应关系，该第二对应关系包括不同的TTI和不同的HARQ进程数之间的对应关系，接入网设备查询上述第二对应关系确定为终端的各个载波分配的HARQ进程数。
在另一个示例中，以载波的特征信息为载波所承载的主要业务类型为例。当载波所承载的业务类型仅为一种时，该种业务类型即为载波所承载的主要业务类型；当载波所承载的业务类型为多种时，该多种业务类型中业务量最大的业务类型作为载波所承载的主要业务类型。对于终端聚合的每一个载波，接入网设备根据该载波所承载的主要业务类型，从上述n个HARQ进程中选择至少一个HARQ进程分配给该载波。例如，如果载波所承载的主要业务类型为时延敏感型业务，则接入网设备为该载波分配较少的HARQ进程数；如果载 波所承载的主要业务类型为时延容忍型业务，则接入网设备为该载波分配较多的HARQ进程数。在实际应用中，接入网设备中可预存第三对应关系，该第三对应关系包括不同的业务类型和不同的HARQ进程数之间的对应关系，接入网设备查询上述第三对应关系确定为终端的各个载波分配的HARQ进程数。
在又一个示例中，以载波的特征信息为载波所在的频带为例。对于终端聚合的每一个载波，接入网设备根据该载波所在的频带，从上述n个HARQ进程中选择至少一个HARQ进程分配给该载波。在通常情况下，载波所在的频带对应的频率大小和载波对应的TTI呈负相关关系，而为载波分配的HARQ进程数与载波对应的TTI呈正相关关系。也即，载波所在的频带对应的频率大小越小，载波对应的TTI越长，为载波分配的HARQ进程数越多；载波所在的频带对应的频率大小越大，载波对应的TTI越短，为载波分配的HARQ进程数越少。在实际应用中，接入网设备中可预存第四对应关系，该第四对应关系包括不同的频带和不同的HARQ进程数之间的对应关系，接入网设备查询上述第四对应关系确定为终端的各个载波分配的HARQ进程数。
上文针对载波聚合场景，介绍了接入网设备根据终端聚合的各个载波的特征信息，为各个载波配置相应的HARQ进程数。在其它可能的实施例中，在给终端聚合的各个载波初始化配置HARQ进程数时，接入网设备将n个HARQ进程中的m个HARQ进程平均分配给终端聚合的各个载波。
对于非载波聚合场景，终端当前支持的载波的数量为1，该载波复用多组不同的基础参数集。接入网设备根据该载波当前所采用的基础参数集，将上述n个HARQ进程中的m个HARQ进程分配给该载波。
以TTI为例，接入网设备根据该载波对应的TTI，从上述n个HARQ进程中选择至少一个HARQ进程分配给该载波。其中，为载波分配的HARQ进程数与载波对应的TTI呈正相关关系。也即，载波对应的TTI越长，为载波分配的HARQ进程数越多；载波对应的TTI越短，为载波分配的HARQ进程数越少。在实际应用中，接入网设备中可预存第二对应关系，该第二对应关系包括不同的TTI和不同的HARQ进程数之间的对应关系，接入网设备查询上述第二对应关系确定为载波分配的HARQ进程数。
上述为载波配置的HARQ进程可称为共享HARQ进程，共享HARQ进程是指为载波动态配置的HARQ进程，载波对应的共享HARQ进程会根据情况动态发生变化。相应地，接入网设备为载波配置共享HARQ进程数，共享HARQ 进程数是指共享HARQ进程的数量，载波对应的共享HARQ进程数会根据情况动态发生变化。
另外，接入网设备可通过DCI向终端发送为终端当前支持的载波初始化配置的HARQ进程数，也可以通过高层信令向终端发送为终端当前支持的载波初始化配置的HARQ进程数。
接入网设备在为终端当前支持的载波初始化配置相应的HARQ进程数之后，会根据实际情况动态调整为终端当前支持的载波分配的HARQ进程数。上述步骤102之后还包括如下步骤：当终端当前支持的载波发生变化时，接入网设备调整为终端当前支持的载波分配的HARQ进程数。
对于载波聚合场景，通过下述几个示例进行介绍说明。
在一个示例中，当终端聚合的载波的特征发生变化时，接入网设备调整为终端聚合的各个载波分配的HARQ进程数。载波的特征包括以下至少一种：载波所采用的基础参数集、载波所承载的主要业务类型、载波所在的频带。例如，当某一载波所承载的主要业务类型由时延敏感型业务变为时延容忍型业务时，接入网设备增加为该载波分配的HARQ进程数。又例如，当某一载波所承载的主要业务类型由时延容忍型业务变为时延敏感型业务时，接入网设备减少为该载波分配的HARQ进程数。再例如，当某一载波对应的TTI变短时，接入网设备减少为该载波分配的HARQ进程数。
在另一个示例中，当终端聚合的载波数量发生变化时，接入网设备调整为终端聚合的各个载波分配的HARQ进程数。对于终端新增聚合的载波，接入网设备为该载波分配HARQ进程数。对于终端新增聚合的载波，如果为终端配置的HARQ进程中还有未分配的HARQ进程，则从未分配的HARQ进程中选择至少一个HARQ进程分配给该载波；如果为终端配置的HARQ进程中没有未分配的HARQ进程，则从分配给其它载波的HARQ进程中选择至少一个HARQ进程分配给该载波。对于终端减少聚合的载波，接入网设备可以将分配给该载波的HARQ进程分配给其它载波，也可以将分配给该载波的HARQ进程回收以供后续分配。
对于非载波聚合场景，通过下述示例进行介绍说明。
当终端当前支持的这一个载波所采用的基础参数集发生变化时，接入网设备调整为该载波分配的HARQ进程数。以TTI为例，当该载波对应的TTI变短时，接入网设备减少为该载波分配的HARQ进程数；当该载波对应的TTI 边长时，接入网设备增加为该载波分配的HARQ进程数。
接入网设备在调整为终端当前支持的载波分配的HARQ进程数之后，向终端发送HARQ配置信息，该HARQ配置信息用于指示为终端当前支持的载波分配的HARQ进程数。可选地，接入网设备通过DCI向终端发送HARQ配置信息。也即，接入网设备向终端发送DCI，该DCI中携带HARQ配置信息。
综上所述，本发明实施例提供的方法，通过为终端配置HARQ进程数n，并将n个HARQ进程中的m个HARQ进程分配给终端当前支持的一个或多个载波；解决了现有技术中HARQ进程的配置和调度的灵活度较低的问题。由于网络侧为每一个终端对应配置HARQ进程数，在载波聚合场景下，终端聚合的各个载波能够共享上述n个HARQ进程，且网络侧能够为终端聚合的各个载波动态调整分配的HARQ进程数，从而提高HARQ进程配置和调度的灵活度，并且有助于降低终端的HARQ缓冲开销；在非载波聚合场景下，终端所支持的一个载波可以复用多组不同的基础参数集，该多组不同的基础参数集能够共享上述n个HARQ进程，当该载波支持的基础参数集发生变化时，网络侧能够为该载波动态调整分配的HARQ进程数，从而提高HARQ进程配置和调度的灵活度。
另外，还通过当终端当前支持的载波发生变化时，动态调整为终端当前支持的载波分配的HARQ进程数，实现了HARQ进程数的按需分配和使用，充分提高了HARQ进程调度的灵活度。
另外，还通过根据终端的特征信息为终端配置HARQ进程数，以及根据终端聚合的各个载波的特征信息给终端聚合的各个载波分配HARQ进程数，使得HARQ进程数的分配更加准确，更加符合实际需求。
需要说明的是，本发明实施例提供的技术方案，适用于上行HARQ进程的配置，也适用于下行HARQ进程的配置。
