Description

一种混合自动重传请求状态增强方法及其装置 技术领域
本申请涉及通信技术领域,尤其涉及一种随机接入请求消息中的混合自动重传请求状态增强方法及其装置。
背景技术
NTN(Non-terrestrial Network,非陆地/地面通信)是5G引入的一项重要技术,它通过卫星(或无人机)而不是地面基站来提供无线资源。依据卫星处理信号的方式的不同可以分为透传模式和再生模式。透传模式如图1所示,NTN地面站将基站gNB的信号发送给卫星,卫星将信号转换到卫星频段后再通过卫星频段下发给终端设备UE,除了频率转换与信号放大,卫星不对gNB信号解调,类似于中继器repeater。再生模式如图2所示,NTN地面站将gNB的信号发送给卫星后,卫星先将信号进行解调译码后再重新编码调制(这个过程就是再生)并通过卫星频段发送再生的信号。
在NTN系统中,支持2步随机接入过程。由于终端设备发起2步随机接入过程时,MsgA的PUSCH(Physical Uplink Shared Channel,物理上行共享信道)payload(有效载荷)只允许使用HARQ process#0(标识为0的混合自动重传请求进程)。当网络给HARQ process#0配置了HARQ状态时,会给使用MsgA PUSCH资源关联的UL grant带来了较大的限制。

具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标识表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。其中,在本申请的描述中,除非另有说明,“/”表示或的意思,例如,A/B可以表示A或B;本文中的“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和 /或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
需要说明的是,NTN(Non-terrestrial Network,非陆地/地面通信)是5G引入的一项重要技术,它通过卫星(或无人机)而不是地面基站来提供无线资源。依据卫星处理信号的方式的不同可以分为透传模式和再生模式。透传模式如图1所示,NTN地面站将基站gNB的信号发送给卫星,卫星将信号转换到卫星频段后再通过卫星频段下发给终端设备UE,除了频率转换与信号放大,卫星不对gNB信号解调,类似于中继器repeater。再生模式如图2所示,NTN地面站将gNB的信号发送给卫星后,卫星先将信号进行解调译码后再重新编码调制(这个过程就是再生)并通过卫星频段发送再生的信号。
在NTN系统中,支持2步随机接入过程(2-Step RA)。如图3中的(a)和(b)所示,对2-Step RA,MsgA由前导码preamble和(Physical Uplink Shared Channel,物理上行共享信道)payload(有效载荷)构成,其相当于4步随机接入过程(4-Step RA)的Msg1+Msg3;2-Step RA的MsgB相当于4-Step RA的Msg2+Msg4。
终端设备在进行2步随机接入过程时,首先会为MsgA的payload选择PUSCH occasion(时机),然后会基于选择的PUSCH occasion来确定MsgA payload的上行授权UL grant和HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)信息。当上行传输MsgA PUSCH payload时,目前只允许使用HARQ process#0(标识为0的混合自动重传请求进程)。MsgA的PUSCH payload所使用的PUSCH资源由网络配置。
需要说明的是,一个终端设备的一个服务小区可以配置高达32个HARQ process,其中一部分HARQ process用于Dynamic grant(动态授权),一部分HARQ process用于configured grant(配置授权)。对NTN,一个HARQ process可以被配置为多种状态(也即目前3GPP讨论中使用的参数uplinkHARQ-DRX-LCP-Mode-r17):
HARQ state A:length of drx-HARQ-RTT-TimerUL is extended by UE-gNB RTT(i.e.UE PDCCH monitoring is optimized to support UL retransmission grant based on UL decoding result).
HARQ state B:drx-HARQ-RTT-TimerUL is not started.
如果不配置状态,则为legacy HARQ state:
Legacy HARQ state:Legacy behavior of drx-HARQ-RTT-TimerUL applies.
其中,上述HARQ state A的定义的中文含义为:上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的长度由终端设备的网络设备UE-gNB往返时间RTT扩展(优化UE物理下行控制信道PDCCH监视以支持基于上行UL解码结果的UL重传授权)。该HARQ state B的定义的中文含义为:上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL未启动。如果不配置状态,则为legacy HARQ state。其中,该遗留Legacy HARQ state的定义的中文含义为:上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的遗留行为适用。
需要说明的是,上述HARQ state A对应着基站基于PUSCH数据的译码结果进行重传调度,HARQ state B对应着基站不基于PUSCH数据的译码结果进行重传调度。对Legacy HARQ state,同样对应着基站不基于PUSCH数据的译码结果进行重传调度。
还需要说明的是,LCP(logical channel prioritization,逻辑信道优先分配流程)用于终 端设备在收到UL grant后,确定各个逻辑信道优先级。LCP支持以下1)至6)的限定参数:
1)allowedSCS-List which sets the allowed Subcarrier Spacing(s)for transmission(允许传输子载波间隔的允许列表用于设置允许的传输子载波间隔);
2)maxPUSCH-Duration which sets the maximum PUSCH duration allowed for transmission(设置最大PUSCH持续时间允许传输的最大持续时间用于设置允许传输的最大PUSCH持续时间);
3)configuredGrantType1Allowed which sets whether a configured grant Type 1can be used for transmission(允许配置授权类型用于设置配置的授权类型1是否可用于传输);
4)allowedServingCells which sets the allowed cell(s)for transmission(允许设置传输的单元格的允许Services单元用于设置允许传输的单元);
5)allowedCG-List which sets the allowed configured grant(s)for transmission(允许传输的允许配置的许可证的AuthEdcg列表用于设置允许传输的配置授权);
6)allowedPHY-PriorityIndex which sets the allowed PHY priority index(es)of a dynamic grant for transmission(允许PHY优先级索引设置传输动态授权的允许PHY优先级索引).
同时,NTN进一步引入了一个新的LCP限制参数:UL HARQ retransmission state(也即上面提到的HARQ state A、B、legacy)。以上参数可以为每个逻辑信道单独配置。对于LCP,终端设备在选择可以使用某个UL grant资源的逻辑信道时,逻辑信道需要满足LCP限制条件。
然而,由于发起2步随机接入过程时,MsgA的PUSCH(Physical Uplink Shared Channel,物理上行共享信道)payload(有效载荷)只允许使用HARQ process#0(标识为0的混合自动重传请求进程)。当网络给HARQ process#0配置了一个HARQstate时,就意味着只有逻辑信道其LCP的HARQ state与HARQ process#0的HARQ state一致时,才能使用该MsgA PUSCH资源关联的UL grant,这带来较大的限制。
基于上述问题,本申请提出了一种随机接入请求消息中的混合自动重传请求状态增强方法,通过增强随机接入请求消息MsgA的HARQ状态,确保能够使用MsgA PUSCH资源关联的UL grant,提高HARQ资源使用效率。
为了更好的理解本申请实施例公开的一种随机接入请求消息中的混合自动重传请求状态增强方法,下面首先对本申请实施例使用的通信系统进行描述。
请参见图4,图4为本申请实施例提供的一种通信系统的架构示意图。该通信系统可以包括但不限于一个基站、一个卫星、一个地面站和一个终端设备,图4所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定,实际应用中可以包括两个或两个以上的基站、卫星、地面站和终端设备。图4所示的通信系统可以包括一个基站110、一个卫星120、一个地面站130和一个终端设备140为例。
本申请实施例中的终端设备140是用户侧的一种用于接收或发射信号的实体,如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端设备(mobile terminal,MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR) 终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
需要说明的是,本申请实施例的技术方案可以应用于NTN通信系统。NTN是5G引入的一项重要技术,它通过卫星(或无人机)而不是地面基站来提供无线资源。依据卫星处理信号的方式的不同可以分为透传模式和再生模式。透传模式如图1所示,NTN地面站将gNB(基站)的信号发送给卫星,卫星将信号转换到卫星频段后再通过卫星频段下发给终端设备UE,除了频率转换与信号放大,卫星不对gNB信号解调,类似于repeater(中继器)。再生模式如图2所示,NTN地面站将gNB的信号发送给卫星后,卫星先将信号进行解调译码后再重新编码调制(这个过程就是再生)并通过卫星频段发送再生的信号。
可以理解的是,本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着系统架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
下面结合附图对本申请所提供的随机接入请求消息中的混合自动重传请求状态增强方法及其装置进行详细地介绍。
请参见图5,图5为本申请实施例提供的一种随机接入请求消息MsgA中的混合自动重传请求状态HARQ state增强方法的流程图。需要说明的是,本申请实施例的MsgA中的HARQ state增强方法可由终端设备执行,也就是说,本申请实施例的MsgA中的HARQ state增强方法可从终端设备侧描述。如图5所示,该增强方法可包括但不限于以下步骤。
在步骤501中,对于随机接入请求消息中上行物理共享信道MsgA PUSCH资源关联的上行授权UL grant,终端设备在进行逻辑信道优先分配流程LCP的逻辑信道选择时,不应用LCP限制条件中的混合自动重传请求状态HARQ state限制条件。
也就是说,对MsgAPUSCH资源关联的上行授权UL grant,不应用LCP限制条件中的HARQ state限制条件。
在一种实现方式中,响应于终端设备发起2步随机接入流程,确定MsgA PUSCH资源关联的UL grant。对MsgAPUSCH资源关联的UL grant,终端设备在进行LCP的逻辑信道选择时,不应用LCP限制条件中的HARQ state限制条件。
也就是说,当终端设备发起2步随机接入流程,确定MsgA PUSCH资源关联的UL grant之后,为了确保能够使用该MsgAPUSCH资源关联的UL grant,终端设备在进行LCP的逻辑信道选择时,可以不应用该LCP限制条件中的HARQ state限制条件。其中,可以理解,HARQ state限制条件是NTN系统中引入的一个新的LCP限制参数。
在本申请的实施例中,HARQ state至少包括以下1)至3)中一项或多项:
1)HARQ state A,HARQ state A用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的长度由终端设备的网络设备UE-gNB往返时间RTT扩展;
2)HARQ state B,HARQ state B用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL未启动;
3)遗留Legacy HARQ state,Legacy HARQ state用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的遗留行为适用。
其中,上述HARQ state A对应着基站基于PUSCH数据的译码结果进行重传调度,HARQ state B对应着基站不基于PUSCH数据的译码结果进行重传调度。对Legacy HARQ state,同样对应着基站不基于PUSCH数据的译码结果进行重传调度。
例如,由于发起2步随机接入流程时,MsgA的PUSCHpayload只允许使用HARQ process#0(标识为0的混合自动重传请求进程)。当网络给HARQ process#0配置了一个HARQstate(比如上述HARQ state A、HARQ state B和Legacy HARQ state中的其中一种)时,为了确保能够使用该MsgAPUSCH资源关联的UL grant,终端设备在进行LCP的逻辑信道选择时,可以不应用该LCP限制条件中的HARQ state限制条件,也就是说,终端设备在选择可以使用UL grant资源的逻辑信道时,不应用该LCP限制条件中的HARQ state限制条件来选择该逻辑信道,这样可以使得选择的逻辑信道可以使用该MsgAPUSCH资源关联的UL grant。
通过实施本申请实施例,通过增强随机接入请求消息MsgA的HARQ状态,确保能够使用MsgA PUSCH资源关联的UL grant,提高HARQ资源使用效率。
请参见图6,图6为本申请实施例提供的另一种随机接入请求消息MsgA中的混合自动重传请求状态HARQ state增强方法的流程图。需要说明的是,本申请实施例的MsgA中的HARQ state增强方法可由终端设备执行,也就是说,本申请实施例的MsgA中的HARQ state增强方法可从终端设备侧描述。如图6所示,该增强方法可包括但不限于以下步骤。
在步骤601中,响应于终端设备在进行LCP的逻辑信道选择,且与MsgA PUSCH资源关联的UL grant对应的混合自动重传请求进程HARQ process没有配置HARQ state,终端设备不应用LCP限制条件中的HARQ state限制条件。
可选地,终端设备在进行LCP的逻辑信道选择时,如果该MsgA PUSCH资源关联的UL grant对应的HARQ process没有配置HARQ state,则终端设备可以不应用LCP限制条件中的HARQ state限制条件。
需要说明的是,在本申请的实施例中,该MsgA PUSCH资源关联的UL grant对应的HARQ process没有配置HARQ state可以理解是:终端设备认为网络设备下发的对于HARQ process的HARQ state配置不适用。例如,终端设备可以认为收到的网络下发的对于HARQ process的HARQ state配置不适用于使用HARQ process 0传输MsgA PUSCH payload的情况。此时,对于使用HARQ process 0传输MsgA PUSCH payload的情况,终端设备认为HARQ process 0m没有配置HARQ state。
在一种实现方式中,终端设备接收网络设备发送的HARQ state配置,其中,该HARQ state配置包括对第一HARQ process的第一HARQ state配置。终端设备可以认为第一HARQ state配置不适用于使用第一HARQ process传输随机接入请求消息中上行物理共享信道有效载荷MsgA PUSCH payload的情况。响应于使用第一HARQ process传输MsgA PUSCH  payload的情况,确定与MsgA PUSCH资源关联的UL grant对应的HARQ process没有配置HARQ state。其中,在本申请的实施例中,第一HARQ process可理解为标识为0的HARQ process。
举例而言,终端设备接收网络设备发送的HARQ state配置,其中包括对第一HARQ process(即标识为0的HARQ process,可表示为HARQ process 0)的HARQ state配置。终端设备可以认为该对第一HARQ process的HARQ state配置不适用于使用第一HARQ process传输MsgA PUSCH payload的情况。此时,对使用第一HARQ process传输MsgA PUSCH payload的情况,终端设备认为第一HARQ process没有配置HARQ state(也即采用legacy HARQ behavior)。终端设备进行LCP的逻辑信道选择时,如果该UL grant对应的HARQ process没有配置HARQ state,则终端设备不应用LCP限制条件中的HARQ state限制条件。
其中,可以理解,HARQ state限制条件是NTN系统中引入的一个新的LCP限制参数。
在本申请的实施例中,HARQ state至少包括以下1)至3)中一项或多项:
1)HARQ state A,HARQ state A用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的长度由终端设备的网络设备UE-gNB往返时间RTT扩展;
2)HARQ state B,HARQ state B用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL未启动;
3)遗留Legacy HARQ state,Legacy HARQ state用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的遗留行为适用。
其中,上述HARQ state A对应着基站基于PUSCH数据的译码结果进行重传调度,HARQ state B对应着基站不基于PUSCH数据的译码结果进行重传调度。对Legacy HARQ state,同样对应着基站不基于PUSCH数据的译码结果进行重传调度。
例如,由于发起2步随机接入流程时,MsgA的PUSCHpayload只允许使用HARQ process 0(标识为0的混合自动重传请求进程)。当终端设备接收到网络设备发送的对HARQ process 0的HARQstate(比如上述HARQ state A、HARQ state B和Legacy HARQ state中的其中一种)配置时,为了确保能够使用该MsgAPUSCH资源关联的UL grant,终端设备可以认为该网络设备发送的对HARQ process 0的HARQstate配置,不适用于使用HARQ process 0传输MsgA PUSCH payload的情况。此时,对使用HARQ process 0传输MsgA PUSCH payload的情况,终端设备可以认为HARQ process 0没有配置HARQ state(也即采用legacy HARQ behavior)。终端设备进行LCP的逻辑信道选择时,如果该UL grant对应的HARQ process没有配置HARQ state,则不应用LCP限制条件中的HARQ state限制条件,也就是说,终端设备在选择可以使用UL grant资源的逻辑信道时,不应用该LCP限制条件中的HARQ state限制条件来选择该逻辑信道,这样可以使得选择的逻辑信道可以使用该MsgAPUSCH资源关联的UL grant。
通过实施本申请实施例,通过增强随机接入请求消息MsgA的HARQ状态,确保能够使用MsgA PUSCH资源关联的UL grant,提高HARQ资源使用效率。
可以理解,上述实施例是从终端设备侧描述本申请实施例的随机接入请求消息中的混合自动重传请求状态增强方法的实现方式。本申请实施例还提出了一种随机接入请求消息中的混合自动重传请求状态增强方法,下面将从网络设备侧描述该随机接入请求消息中的混合自动重传请求状态增强方法的实现方式。请参见图7,图7为本申请实施例提供的又一种随机接入请求消息中的混合自动重传请求状态增强方法的流程图。需要说明的是,本申请实施例的随机接入请求消息中的混合自动重传请求状态增强方法可应用于非地面网络系统,该系统可由网络设备执行。如图7所示,该增强方法可以包括但不限于如下步骤。
在步骤701中,向终端设备发送混合自动重传请求状态HARQ state配置;HARQ state配置包括对第一混合自动重传请求进程HARQ process的第一HARQ state配置。
其中,在本申请的实施例中,第一HARQ state配置用于指示终端设备认为第一HARQ state配置不适用于使用第一HARQ process传输随机接入请求消息中上行物理共享信道有效载荷MsgA PUSCH payload的情况,不应用逻辑信道优先分配流程LCP限制条件中的HARQ state限制条件。
在本申请的实施例中,第一HARQ process可理解是标识为0的HARQ process。
其中,在本申请的实施例中,HARQ state至少包括以下1)至3)中一项或多项:
1)HARQ state A,HARQ state A用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的长度由终端设备的网络设备UE-gNB往返时间RTT扩展;
2)HARQ state B,HARQ state B用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL未启动;
3)遗留Legacy HARQ state,Legacy HARQ state用于表示上行的非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL的遗留行为适用。
在一种实现方式中,网络设备可以向终端设备发送HARQ state配置,该HARQ state配置可以包括对HARQ process0(即第一HARQ process,也就是标识为0的HARQ process)的HARQ state配置。终端设备认为该配置不适用于使用HARQ process 0传输MsgA PUSCH payload的情况。此时,对使用HARQ process 0传输MsgA PUSCH payload的情况,终端设备认为HARQ process 0没有配置HARQ state(也即采用legacy HARQ behavior)。终端设备进行LCP的逻辑信道选择时,如果该UL grant对应的HARQ process没有配置HARQ state,则不应用LCP限制条件中的HARQ state限制条件。
通过实施本申请实施例,通过增强随机接入请求消息MsgA的HARQ状态,确保能够使用MsgA PUSCH资源关联的UL grant,提高HARQ资源使用效率。
