Abstract

本申请实施例提供一种上行数据的重传方法、装置及设备,先接收来自网络设备的资源配置消息,该资源配置消息包括配置授权资源的信息和第一指示信息,若第一指示信息指示在传输第一上行数据时目标进程对应的定时器运行时,允许在与目标进程关联的目标配置授权资源上进行第一上行数据重传,则终端设备可以根据在目标进程关联的目标配置授权资源上进行第一上行数据重传,直至满足预设条件,那么该目标配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率较低,从而提高了配置授权资源的利用率。且由于在目标配置授权资源上进行数据重传,这样网络设备就可以将多次接收到第一上行数据进行合并解码,从而提高了网络设备的解码成功率。

Description

上行数据的重传方法、装置及设备 技术领域
本申请实施例涉及通信技术,尤其涉及一种上行数据的重传方法、装置及设备。
背景技术
对于处于连接态用户设备(User Equipment,简称UE),其在执行上传数据传输和下行数据传输时,所使用的网络资源通常是由基站动态调度的。为了更好地服务于周期性的业务,在第五代(5th-Generation,简称5G)移动通信技术系统中引入了预配置的资源的概念,该预配置资源可以分为半持续调度(Semi persistent scheduling,简称SPS)资源和配置授权(Configured Grant,简称CG)资源。其中,SPS资源用于下行数据传输,CG资源用于上行数据传输。对于CG资源,其通常是按照周期出现的方式配置的资源,CG资源的配置信息可以包括跳频模式,调制编码等级,资源分配等。
在通过CG资源进行上行数据传输时,在新空口(new radio,简称NR)系统中引入了配置授权定时器(Configured Grant timer,简称CG timer)的概念,在NR-U系统中引入了配置授权重传定时器(Configured Grant retransmission timer,简称CG retransmission timer)的概念。以CG timer为例,基站会预先为UE配置多个CG资源,该CG资源用于传输上行数据,且会为传输上行数据时关联的混合自动重传请求(Hybrid Automatic Repeat-reQuest,简称HARQ)进程设置对应的CG timer,当某个HARQ进程对应的CG timer正在运行时,该UE不会在其它CG资源上进行数据传输,这样其它CG资源会处于空闲状态。当其它CG资源会处于空闲状态时,且当CG资源为UE的专属资源时,其它CG资源会一直处于空闲状态,导致CG资源的利用率较低,并且,对于UE而言,仅通过一个CG资源传输上传数据,可能会因为上行数据传输失败,导致上行数据的接收端基站的解码成功率较低。
因此,在CG资源上进行上行数据传输的过程中,如何实现在提高CG资源的利用率的基础上,提高上行数据接收端的解码成功率是本领域技术人员亟待解决的问题。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例应用于通信系统,例如第五代(5th generation,5G)通信系统或未来可能出现的其他系统,以下对本申请中的部分用语进行解释说明,以便于本领域技术人员理解。需要说明的是,当本申请实施例的方案应用于5G系统或未来可能出现的其他系统时,网络设备和终端设备的名称可能发生变化,但这并不影响本申请实施例方案的实施。
图1为本申请实施例提供的一种应用场景示意图,该通信系统可以包括一个网络设备和至少一个终端设备。示例的,请参见图1所示,以通信系统包括一个网络设备和一个终端设备为例,终端设备在进行上行数据传输之前,网络设备会预先为该终端设备分配多个CG资源,该CG资源用于终端设备传输上行数据,且会为传输上行数据时关联的HARQ进程设置对应的CG timer,当某个HARQ进程对应的CG timer正在运行时,该UE不会在其它CG资源上进行上行数据传输,这样其它CG资源会处于空闲状态。尤其是当该多个CG资源均为UE的专属CG资源时,该其它CG资源会一直处于空闲状态,导致CG资源的利用率较低,并且,对于UE而言,仅通过一个CG资源传输上传数据,可能会因为上行数据传输失败,导致上行数据的接收端基站的解码成功率较低。
可以看出,在现有技术中,在CG资源上进行上行数据传输的过程中,导致CG资源的利用率较低,且上行数据接收端的解码成功率较低的原因为:当某个HARQ进程对应的CG timer正在运行时,该UE不会通过其它CG资源进行数据传输,使得该其它CG资源会处于空闲状态,且由于其它CG资源为UE的专属资源,即使该其它CG资源处于空闲状态,其它UE也不能使用该其它CG资源进行上行数据传输,因此,会导致CG资源的利用率较低,且UE仅通过某一个CG资源传输上传数据,这样上行数据接收端只能通过一次接收到的上行数据进行解码,从而导致上行数据接收端的解码成功率较低。
为了提高CG资源的利用率,且提高上行数据接收端的解码成功率,本申请实施例提供了一种上行数据的重传方法,请参见图2所示,图2为本申请实施例提供的一种上行数据的重传方法的流程示意图,该方法包括:S201、终端设备先接收来自网络设备的资源配置消息,与现有技术不同的是,本申请实施例中的资源配置消息不仅包括配置授权资源的信息,还包括第一指示信息,该第一指示信息用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在配置授权资源中与目标进程关联的目标配置授权资源上进行第一上行数据重传;S202、若第一指示信息指示允许在目标配置授权资源上进行第一上行数据重传,则终端设备在目标进程关联的目标配置授权资源上进行第一上行数据重传,直至满足预设条件。由此可见,在本申请实施例中,在目标进程对应的定时器运行期间,终端设备可以根据第一指示信息在目标进程关联的目标配置授权资源上进行第一上行数据重传,这些该目标配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率 较低,从而提高了配置授权资源的利用率。并且,由于终端设备在目标配置授权资源上进行第一上行数据重传,这样第一上传数据的接收端网络设备也可以多次接收到该第一上行数据,以将多次接收到第一上行数据进行合并解码,从而提高了网络设备的解码成功率。
需要说明的是,终端设备在目标配置授权资源上进行第一上行数据重传时,不是无限制地执行第一上行数据的重传操作,而是当满足预设条件时,即可停止第一上行数据的重传操作。可选的,预设条件可以包括定时器(即为目标进程对应的定时器)超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的至少一种;动态调度指示消息用于指示终端设备通过网络设备为其通过PDCCH动态调度的资源进行第二上行数据传输。当然,本申请实施例只是以预设条件可以包括定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的至少一种为例进行说明,具体可以根据实际需要进行设置,在此,本申请实施例不做进一步地限制。
可以看出,预设条件可以包括定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的任意一种,也可以同时包括定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的任意两种,当然,也可以同时包括定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息。可以理解的是,当预设条件同时包括定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的任意两种或者三种时,可以根据至少两种方式判断是否需要停止第一上行数据的重传操作。在一种方式中,可以根据各条件被满足的时间先后顺序判断是否需要停止第一上行数据的重传操作。具体为:由于任意两种条件可能不是同一时刻被满足,因此,当任意两种条件或者三种条件中只要有一个条件先被满足,即可停止第一上行数据的重传操作。例如,当预设条件包括定时器超时和数据重传次数达到最大重传次数时,以数据重传次数为4次,且定时器运行时长为10ms为例,当数据重传次数达到最大重传次数4次时,定时器还未超时,即定时器超时的条件未被满足,此时,由于数据重传次数达到最大重传次数的条件已经被满足,因此,可停止第一上行数据的重传操作。在另一种方式中,可以根据各条件的优先级判断是否需要停止第一上行数据的重传操作。具体为:可以预先设置各条件对应的优先级,只有当优先级较高的条件被满足时,才停止第一上行数据的重传操作。例如,当预设条件包括数据重传次数达到最大重传次数和接收到网络设备发送的动态调度指示消息时,以数据重传次数达到最大重传次数对应的优先级高于接收到网络设备发送的动态调度指示消息对应的优先级为例,当终端设备接收到网络设备发送的动态调度指示消息时,即终端设备接收到网络设备发送的动态调度指示消息的条件被满足,但是由于数据重传次数达到最大重传次数对应的优先级高于接收到网络设备发送的动态调度指示消息对应的优先级,因此,可继续执行第一上行数据的重传操作,只有在数据重传次数达到最大重传次数,即数据重传次数达到最大重传次数的条件被满足时,才停止第一上行数据的重传操作。当然,本申请实施例只是以这两种方式为例进行说明,具体可以根据实际需要进行设置,在此,本申请实施例不做进一步地限制。
在上述描述中,当预设条件包括数据重传次数达到最大重传次数时,终端设备需要根据数据重传次数是否达到最大重传次数,以判断是否停止第一上行数据的重传操作。在该种情况下,终端设备必然需要先获取到该最大重传次数。可选的,终端设备在获取该最大重传次数时,可以通过网络设备发送的资源配置消息获取该最大重传次数,即该最大重传次数可以被网络设备携带在资源配置消息中发送给终端设备。当然,也可以通过网络设备发送的一个单独的指示消息获取该最大重传次数,即该最大重传次数也可以被网络设备携带在一个单独的指示消息发送给终端设备,具体可以根据实际需要进行设置,在此,对于最大重传次数的获取方式,本申请实施例不做进一步地限制。
其中,1)终端设备,又称为终端、用户设备,是一种向用户提供语音和/或数据连通 性的设备,例如,具有无线连功能的手持式设备、车载设备等。常见的终端设备例如包括:手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,其中,可穿戴设备例如包括:智能手表、智能手环、计步器等。
2)网络设备可以是蜂窝网络中的接入设备,例如5G基站,或者未来新的网络系统中的基站等等,其覆盖范围示例为实线圈内区域。也可以是无线局域网(Wireless Local Area Networks,简称:WLAN)中的接入点(Access Point,简称:AP)等设备。
综上所述,可以看出,在本申请实施例中,正是因为网络设备向终端设备发送的配置授权资源消息中包括第一指示消息,且当第一指示信息指示在传输第一上行数据时目标进程对应的定时器运行时,允许在目标配置授权资源上进行第一上行数据重传,终端设备才可以在目标进程对应的定时器运行期间,在目标进程关联的目标配置授权资源上进行第一上行数据重传,这些该目标配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率较低,从而提高了配置授权资源的利用率。并且,由于终端设备在目标配置授权资源上进行第一上行数据重传,这样网络设备可以将多次接收到第一上行数据进行合并解码,从而提高了网络设备的解码成功率。由于终端设备是在目标进程对应的定时器运行期间,在目标进程关联的目标配置授权资源上进行第一上行数据重传,因此,终端设备必然要先控制目标进程对应的定时器启动,这样终端设备才能在目标进程对应的定时器运行期间,在目标进程关联的目标配置授权资源上进行第一上行数据重传。
众所周知,当本申请实施例提供的上行数据的重传方法应用的系统不同时,目标进程对应的定时器也不同。具体为:当该上行数据的重传方法应用于NR系统时,该目标进程对应的定时器为配置授权定时器,即CG timer;当该上行数据的重传方法应用于NR-U系统时,该目标进程对应的定时器为配置授权重传定时器,即CG retransmission timer。这两种定时器的相同之处在于:若第一指示信息指示在传输第一上行数据时目标进程对应的定时器运行时,允许在目标配置授权资源上进行第一上行数据重传,则在CG timer定时器或者CG retransmission timer运行期间,终端设备均可在目标进程关联的目标配置授权资源上进行第一上行数据重传。这两种定时器的不同之处在于:若第一指示信息指示在传输第一上行数据时目标进程对应的定时器运行时,允许在目标配置授权资源上进行第一上行数据重传,则当目标进程对应的定时器为CG timer定时器时,在该CG timer定时器超时后,终端设备可在目标配置授权资源上进行新的上行数据的传输;当目标进程对应的定时器为CG retransmission timer定时器时,在该CG retransmission timer定时器超时后,终端设备可在目标配置授权资源上进行第一上行数据的重传。若第一指示信息指示在传输第一上行数据时目标进程对应的定时器运行时,不允许在目标配置授权资源上进行第一上行数据重传,则当目标进程对应的定时器为CG timer定时器时,在该CG timer定时器超时或者停止后,终端设备可在目标配置授权资源上进行新的上行数据的传输;当目标进程对应的定时器为CG retransmission timer定时器时,在该CG retransmission timer定时器超时或者停止后,终端设备可在目标配置授权资源上进行第一上行数据的重传。
无论目标进程对应的定时器为上述两种定时器的哪一种定时器,终端设备在目标进程关联的目标配置授权资源上进行第一上行数据重传之前,必然需要先控制目标进程对应的定时器启动。可选的,终端设备在控制目标进程对应的定时器启动时,可以通过至少两种可能的实现方式控制定时器启动。在一种可能的实现方式中,终端设备可以在目标进程关联的第一配置授权资源(为网络设备为终端设备配置的配置授权资源中的资源)上传输第一上行数据时,控制目标进程对应的定时器启动,即第一上行数据在目标进程关联的第一配置授权资源上进行初传时,控制目标进程对应的定时器启动。在另一种可能的实现方式中,终端设备可以在目标进程关联的动态调度资源上传输第一上行数据时,控制目标进程对应的定时器启动,即第一上行数据在目标进程关联的动态调度资源(不为网络设备为终端设备配置的配置授权资源中的资源)上进行初传时,控制目标进程对应的定时器启动。 当然,本申请实施例只是以这两种可能的实现方式控制目标进程对应的定时器启动为例进行说明,但并不代表本申请实施例仅局限于此。下面,将结合这两种不同的实现方式,详细描述在控制目标进程对应的定时器启动之后,终端设备在该目标进程对应的定时器运行期间,如何实现上行数据的重传的技术方案。
可以理解的是,上述描述只是针对一次上行数据传输,仅启动CG timer定时器或者CG retransmission timer中的任一个定时器为例进行说明,当然,针对一次上行数据传输,也可以同时启动两个定时器,即CG timer和CG retransmission timer同时启动,但是需要分别配置CG timer和CG retransmission timer的长度。示例的,在分别配置CG timer和CG retransmission timer的长度时,CG timer和CG retransmission timer的长度可以相同,也可以不相同。
在一种可能的实现方式中,即终端设备在目标进程关联的第一配置授权资源上传输第一上行数据时,控制目标进程对应的定时器启动。并结合该种可能的控制方式,在目标进程对应的定时器启动之后,终端设备就可以执行本申请实施例提供的上行数据的重传方法的技术方案。示例的,请参见图3所示,图3为本申请实施例提供的另一种上行数据的重传方法的流程示意图,该方法可以包括:
S301、网络设备向终端设备发送资源配置消息。
其中,资源配置消息包括配置授权资源的信息和第一指示信息,第一指示信息用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在配置授权资源中与该目标进程关联的目标配置授权资源上进行第一上行数据重传。
示例的,网络设备在向终端设备发送该资源配置消息时,该资源配置消息可以携带在无线资源控制(Radio Resource Control,简称RRC)信令中,也可以携带在物理层信令中,当然,也可以携带在媒体访问控制地址(Media Access Control Address,MAC)信令中,当然,也可以携带在其它信令中,在此,本申请实施例只是以携带在这三种信令中为例进行说明,但并不代表本申请实施例仅局限于此。
可以看出,在本申请实施例中,网络设备向终端设备发送的资源配置消息,与现有技术不同的是,本申请实施例中的资源配置消息不仅包括配置授权资源的信息,还包括第一指示信息。可以理解的是,当网络设备向终端设备发送第一指示信息时,该第一指示信息可以与配置授权资源的信息一起包含在资源配置消息中发送给终端设备,也可以不与配置授权资源的信息一起包含在资源配置消息中发送给终端设备,即第一指示信息可以携带在资源配置消息之外的某一条指示消息中发送给终端设备,以使终端设备获取到该第一指示信息。在此,本申请实施例只是以第一指示信息与配置授权资源的信息一起包含在资源配置消息中发送给终端设备为例进行说明,具体可以根据实际需要进行设置,在此,对于第一指示信息的发送方式,本申请实施例不做进一步地限制。
毋庸置疑的是,网络设备不管通过上述何种方式向终端设备发送包括配置授权资源的信息和第一指示信息的资源配置消息,均需要在发送资源配置消息之前,预先为终端设备分配其专属的配置授权资源,之后,再将为该终端设备分配的专属配置授权资源的信息发送给终端设备,以使终端设备根据该配置授权资源的信息确定为其分配的配置授权资源。示例的,配置授权资源的信息可以为配置授权周期信息和频域资源位置信息,即网络设备可以将该配置授权周期信息和频域资源位置信息发送给终端设备;对应的,终端设备在接收到该配置授权周期信息和频域资源位置信息后,可以根据该配置授权周期和频域资源位置确定配置授权资源确定网络设备为其分配的专属配置授权资源,从而获取该专属配置授权资源。
对于终端设备而言,在分别获取到网络设备为其分配的配置授权资源和第一指示信息之后,终端设备就可以根据该第一指示信息,判断在传输第一上行数据时目标进程对应的定时器运行时,是否允许该终端设备在配置授权资源中的目标配置授权资源上进行第一上 行数据重传,即执行下述S302:
S302、终端设备根据第一指示信息,判断在目标进程对应的定器运行时,是否允许该终端设备在配置授权资源中与目标进程关联的目标配置授权资源上进行第一上行数据重传。
需要说明的是,在该种可能的实现方式中,由于第一上行数据是在目标进程关联的第一配置授权资源上进行初传的,那么,终端设备在传输第一上行数据时目标进程对应的定器运行期间,若要在配置授权资源中的目标配置授权资源上进行第一上行数据重传,则网络设备需要预先为终端设备配置至少两个与目标进程关联的配置授权资源,即网络设备为终端设备配置的配置授权资源中,必须包括至少两个与目标进程关联的配置授权资源,即与目标进程关联的配置授权资源的个数至少为两个,该至少两个与目标进程关联的配置授权资源包括一个第一授权配置资源和至少一个与目标进程关联的第二配置授权资源,对应的,进行第一上行数据重传的目标配置授权资源即为该至少一个第二配置授权资源中的任一个第二配置授权资源。换言之,第一指示信息用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在第二配置授权资源上进行第一上行数据重传,这样终端设备可以根据第一指示信息,判断在目标进程对应的定器运行时,是否允许该终端设备在第二配置授权资源上进行第一上行数据重传。
可以看出,上述在描述网络设备为终端设备配置的专属配置授权资源时,只是限定了该专属配置授权资源包括至少两个与目标进程关联的配置授权资源,当然,该专属配置授权资源也可以包括不与目标进程关联的配置授权资源,例如,与目标进程不同的进程关联的第三配置授权资源。当专属配置授权资源中包括与目标进程不同的进程关联的第三配置授权资源时,在传输第一上行数据时目标进程对应的定器运行期间,终端设备若要在配置授权资源中的目标配置授权资源上进行第一上行数据重传,则需要先根据该目标进程的信息,在专属配置授权资源中除第一配置授权资源之外的其它配置授权资源中,查找具有相同的目标进程的第二配置授权资源;并在查找的第二配置授权资源上进行第一上行数据重传,这样可以避免终端设备在与目标进程不同的进程关联的第三配置授权资源上进行第一上行数据重传。
可以理解的是,终端设备若要根据该目标进程的信息,在专属配置授权资源中除第一配置授权资源之外的其它配置授权资源中,查找具有相同的目标进程的第二配置授权资源,则需要分别获取到各专属配置授权中每一个配置授权资源关联的进程的信息。示例的,网络设备可以预先为该终端设备的每一个配置授权资源预留其关联的进程,并将每一个配置授权资源关联的进程的信息发送给终端设备,以使终端设备获取到每一个配置授权资源关联的进程的信息。可选的,网络设备在将每一个配置授权资源关联的进程的信息发送给终端设备时,该每一个配置授权资源关联的进程的信息可以与配置授权资源的信息一起包含在资源配置消息中发送给终端设备,也可以不与配置授权资源的信息一起包含在资源配置消息中发送给终端设备,即该每一个配置授权资源关联的进程的信息可以携带在资源配置消息之外的某一条消息中发送给终端设备,以使终端设备获取到该每一个配置授权资源关联的进程的信息,具体可以根据实际需要进行设置,在此,对于每一个配置授权资源关联的进程的信息的发送方式,本申请实施例不做进一步地限制。
示例的,配置授权资源关联的进程的信息可以用进程数表示,例如,进程数为3,终端设备可以根据进程数3,默认从0开始计数,就可以得到网络设备为其配置授权资源预留的进程,即进程0、进程1及进程2;当然,配置授权资源关联的进程的信息可以直接为进程的标识,例如进程0、进程1及进程2,以使终端设备获取到每一个配置授权资源关联的进程的信息。
结合S302中的相关描述可知,在该实施例中,第一指示信息可用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在第二配置授权资源上进行第一上行 数据重传,这样终端设备就可以根据该第一指示信息,判断在目标进程对应的定器运行时,是否允许该终端设备在第二配置授权资源上进行第一上行数据重传,并根据判断结果执行下述S303或S304:
S303、若第一指示信息指示允许在第二配置授权资源上进行第一上行数据重传,则在目标进程关联的第二配置授权资源上进行第一上行数据重传,直至满足预设条件。
其中,预设条件为定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的至少一种;动态调度指示消息用于指示终端设备通过网络设备为其动态配置的授权资源进行第二上行数据传输。
可选的,在目标进程关联的第二配置授权资源上进行第一上行数据重传时,终端设备的控制模块会向终端设备的进程模块发送上行链路授权信息和第二指示信息,该第二指示信息用于指示网络设备未接收到第一上行数据;对应的,进程模块可以根据上行链路授权信息和第二指示信息,触发在目标进程关联的第二配置授权资源上进行第一上行数据重传。需要说明的是,进程模块触发终端设备在目标进程关联的第二配置授权资源上进行第一上行数据重传时,不会控制目标进程对应的定时器重启,即该目标进程对应的定时器会顺着当前的运行时间继续运行。
示例的,终端设备的控制模块和进程模块可以均为软件模块,即通过软件程序实现控制模块和进程模块的功能。第二指示信息可以为Nack(Negative Acknowledgement)消息,以通过该Nack消息指示网络设备未接收到第一上行数据,基于此,终端设备的进程模块就可以触发在目标进程关联的第二配置授权资源上进行第一上行数据重传。
由此可见,在本申请实施例中,若第一指示信息指示允许在第二配置授权资源上进行第一上行数据重传,则终端设备在目标进程对应的定时器运行期间,在目标进程关联的第二配置授权资源上重传第一上行数据,这些第二配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率较低,从而提高了配置授权资源的利用率。并且,由于终端设备在第二配置授权资源上进行第一上行数据重传,对应的,网络设备也会接收到终端设备重传的第一上行数据,这样网络设备就可以将多次接收到第一上行数据进行合并解码,从而提高了网络设备的解码成功率。
S304、若第一指示信息指示不允许在第二配置授权资源上进行第一上行数据重传,则在目标进程对应的定时器超时或者停止时,在目标进程关联的第二配置授权资源上进行第一上行数据重传,或者,在目标进程关联的第二配置授权资源上传输第二上行数据。
若第一指示信息指示不允许在第二配置授权资源上进行第一上行数据重传,则需要根据目标进程对应的定时器的类型确定在定时器超时或者停止时,在第二配置授权资源上进行新的第二上行数据的传输,或者在第二配置授权资源上进行第一上行数据的重传。
若目标进程对应的定时器为CG timer定时器,则在该CG timer定时器超时或者停止时,终端设备在第二配置授权资源上进行新的第二上行数据的传输;若目标进程对应的定时器为CG retransmission timer定时器,则在该CG retransmission timer超时或者停止时,终端设备在第二配置授权资源上进行第一上行数据重传。
需要说明的是,在执行完S302之后,只需要根据S302中的判断结果执行S303或S304中的任一个,即S303和S304不能同时执行,此外,S303和S304之间并无先后顺序。
为了便于理解图3所示的实施例中提供的上行数据的重传方法,下面,将举例说明本申请实施例提供的上行数据的重传方法。在该举例说明中,目标进程对应的定时器为CG timer定时器,可结合图4和图5所示,图4为本申请实施例提供的一种允许在第二配置授权资源上进行上行数据重传的示意图,图5为本申请实施例提供的一种不允许在第二配置授权资源上进行上行数据重传的示意图。结合图4和图5可以看出,网络设备预先为终端设备配置了8个配置授权资源,该8个配置授权资源中有4个配置授权资源关联的进程为HARQ进程0,有4个配置授权资源关联的进程为HARQ进程1。
在执行本申请实施例提供的上行数据的重传方法之前,网络设备会将预先为终端设备配置的8个专属配置授权资源各自的信息和第一指示信息包含在资源配置消息中发送给终端设备,示例的,该资源配置消息中还可包括允许重传的最大重传次数2和预留的HARQ进程数2。对应的,终端设备在接收到网络设备发送的资源配置消息之后,可以根据8个专属配置授权资源各自的信息确定网络设备为其配置的专属配置授权资源,并根据预留的HARQ进程数2确定网络设备为其预留的HARQ进程为HARQ进程0和HARQ进程1。这样在HARQ进程0关联的第一配置授权资源上传输数据块1时,终端设备可以控制HARQ进程0对应的CG timer定时器启动,且在HARQ进程0关联的第一配置授权资源上传输数据块2时,控制HARQ进程1对应的CG timer定时器启动。在HARQ进程0对应的CG timer定时器启动时,且在HARQ进程1对应的CG timer定时器启动时,终端设备可以根据第一指示信息,判断在HARQ进程0对应的CG timer定时器运行期间,是否允许在HARQ进程0关联的其它任意一个第二配置授权上进行数据块1的重传,且在HARQ进程1对应的CG timer定时器运行期间,是否允许在HARQ进程1关联的其它任意一个第二配置授权上进行数据块1的重传,并根据判断结果执行相应的操作。
若第一指示信息指示允许终端设备在第二配置授权资源上进行上行数据重传,且允许重传的最大重传次数均为2,可结合图4所示,则在HARQ进程0对应的CG timer定时器运行期间,终端设备可以在HARQ进程0关联的其它任意一个第二配置授权上进行数据块1的重传,当数据块1的重传次数达到最大重传次数2次时,即使HARQ进程0对应的CG timer定时器还未超时,此时,终端设备仍需要停止在第二配置授权上重传数据块1,直至HARQ进程0对应的CG timer定时器超时之后,终端设备才会在该第二配置授权上进行数据块3的传输,这些第二配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率较低,从而提高了配置授权资源的利用率。并且,由于终端设备在第二配置授权资源上进行数据块1的重传,对应的,网络设备也会接收到重传的数据块1,这样网络设备就可以将多次接收到数据块1进行合并解码,从而提高了网络设备的解码成功率。同样的,在HARQ进程1对应的CG timer定时器运行期间,终端设备可以在HARQ进程1关联的其它任意一个第二配置授权上进行数据块2的重传,当数据块2的重传次数达到最大重传次数2次时,即使HARQ进程1对应的CG timer定时器还未超时,此时,终端设备仍需要停止在该第二配置授权上重传数据块2,直至HARQ进程1对应的CG timer定时器超时之后,终端设备才会在该第二配置授权上进行数据块4的传输,这些第二配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率较低,从而提高了配置授权资源的利用率。并且,由于终端设备在第二配置授权资源上进行数据块2的重传,对应的,网络设备也会接收到重传的数据块2,这样网络设备就可以将多次接收到数据块2进行合并解码,从而提高了网络设备的解码成功率。
相反的,若第一指示信息指示不允许在第二配置授权资源上进行上行数据重传,可结合图5所示,则在HARQ进程0对应的CG timer定时器运行期间,终端设备不会在HARQ进程0关联的其它任意一个第二配置授权上进行数据块1的重传,而是待HARQ进程0对应的CG timer定时器超时或者停止之后,终端设备才会在HARQ进程0关联的其它任意一个第二配置授权上进行数据块3的传输。同样的,在HARQ进程1对应的CG timer定时器运行期间,终端设备不会在HARQ进程1关联的其它任意一个第二配置授权上进行数据块2的重传,而是待HARQ进程1对应的CG timer定时器超时或者停止之后,终端设备才会在HARQ进程1关联的其它任意一个第二配置授权上进行数据块4的传输。
上述图3所示的实施例详细描述在一种可能的实现方式中,终端设备在目标进程关联的第一配置授权资源上传输第一上行数据时,控制目标进程对应的定时器启动。并结合该种可能的控制方式,在目标进程对应的定时器启动之后,终端设备如何执行本申请实施例提供的上行数据的重传方法的技术方案。下面,将详细描述在另一种可能的实现方式中, 即终端设备在目标进程关联的动态调度资源上传输第一上行数据时,控制目标进程对应的定时器启动。并结合该种可能的控制方式,在目标进程对应的定时器启动之后,终端设备如何执行本申请实施例提供的上行数据的重传方法的技术方案。示例的,请参见图6所示,图6为本申请实施例提供的另一种上行数据的重传方法的流程示意图,该方法可以包括:
S601、网络设备向终端设备发送资源配置消息。
其中,资源配置消息包括配置授权资源的信息和第一指示信息,第一指示信息用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在配置授权资源中与目标进程关联的目标配置授权资源上进行第一上行数据重传。
可以理解的是,在该S601中,其相关描述与上述S301中的相关描述类似,可参见上S301中的相关描述,在此,本申请实施例不再进行赘述。
对于终端设备而言,在分别获取到网络设备为其分配的配置授权资源和第一指示信息之后,终端设备就可以根据该第一指示信息,判断在传输第一上行数据时目标进程对应的定时器运行时,是否允许该终端设备在配置授权资源中的目标配置授权资源上进行第一上行数据重传,即执行下述S602:
S602、根据第一指示信息,判断在目标进程对应的定器运行时,是否允许该终端设备在配置授权资源中与目标进程关联的目标配置授权资源上进行第一上行数据重传。
需要说明的是,在该种可能的实现方式中,与图3所示的实施例不同的是,由于第一上行数据是在目标进程关联的动态调度资源上进行初传的,那么,终端设备在传输第一上行数据时目标进程对应的定器运行期间,若要在配置授权资源中的目标配置授权资源上进行第一上行数据重传,则网络设备需要预先为终端设备配置至少一个与目标进程关联的配置授权资源,即网络设备为终端设备配置的配置授权资源中,必须包括至少一个与目标进程关联的配置授权资源,即与目标进程关联的配置授权资源的个数至少为一个,对应的,进行第一上行数据重传的目标配置授权资源即为该至少一个与目标进程关联的配置授权资源中的任一个第四配置授权资源。换言之,第一指示信息用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在第四配置授权资源上进行第一上行数据重传,这样终端设备可以根据第一指示信息,判断在目标进程对应的定器运行时,是否允许该终端设备在第四配置授权资源上进行第一上行数据重传。
可以看出,上述在描述网络设备为终端设备配置的专属配置授权资源时,只是限定了该专属配置授权资源包括至少一个与目标进程关联的配置授权资源,当然,该专属配置授权资源也可以包括不与目标进程关联的配置授权资源,例如,与目标进程不同的进程关联的第三配置授权资源。当专属配置授权资源中包括与目标进程不同的进程关联的第三配置授权资源时,在传输第一上行数据时目标进程对应的定器运行期间,终端设备若要在配置授权资源中的目标配置授权资源上进行第一上行数据重传,则需要先根据该目标进程的信息,在专属配置授权资源中,查找具有相同的目标进程的第四配置授权资源;并在查找的第四配置授权资源上进行第一上行数据重传,这样可以避免终端设备在与目标进程不同的进程关联的第三配置授权资源上进行第一上行数据重传。
同样可以理解的是,终端设备若要根据该目标进程的信息,在专属配置授权资源中,查找具有相同的目标进程的第四配置授权资源,则需要分别获取到各专属配置授权中每一个配置授权资源关联的进程的信息。示例的,网络设备可以预先为该终端设备的每一个配置授权资源预留其关联的进程,并将每一个配置授权资源关联的进程的信息发送给终端设备,以使终端设备获取到每一个配置授权资源关联的进程的信息。可选的,网络设备在将每一个配置授权资源关联的进程的信息发送给终端设备时,该每一个配置授权资源关联的进程的信息可以与配置授权资源的信息一起包含在资源配置消息中发送给终端设备,也可以不与配置授权资源的信息一起包含在资源配置消息中发送给终端设备,即该每一个配置授权资源关联的进程的信息可以携带在资源配置消息之外的某一条消息中发送给终端设 备,以使终端设备获取到该每一个配置授权资源关联的进程的信息,具体可以根据实际需要进行设置,在此,对于每一个配置授权资源关联的进程的信息的发送方式,本申请实施例不做进一步地限制。
结合S602中的相关描述可知,在该实施例中,第一指示信息用于指示在传输第一上行数据时目标进程对应的定时器运行时,是否允许在第四配置授权资源上进行第一上行数据重传,这样终端设备可以根据第一指示信息,判断在目标进程对应的定器运行时,是否允许该终端设备在第四配置授权资源上进行第一上行数据重传,并根据判断结果执行下述S603或S604:
S603、若第一指示信息指示允许在第四配置授权资源上进行第一上行数据重传,则在第四配置授权资源上进行第一上行数据重传,直至满足预设条件。
其中,预设条件为定时器超时、数据重传次数达到最大重传次数、或者接收到网络设备发送的动态调度指示消息中的至少一种;动态调度指示消息用于指示终端设备通过网络设备为其动态配置的授权资源进行第二上行数据传输。
可选的,在目标进程关联的第四配置授权资源上进行第一上行数据重传时,终端设备的控制模块会向终端设备的进程模块发送上行链路授权信息和第二指示信息,该第二指示信息用于指示网络设备未接收到第一上行数据;对应的,进程模块可以根据上行链路授权信息和第二指示信息,触发在目标进程关联的第四配置授权资源上进行第一上行数据重传。需要说明的是,进程模块触发终端设备在目标进程关联的第四配置授权资源上进行第一上行数据重传时,不会控制目标进程对应的定时器重启,即该目标进程对应的定时器会顺着当前的运行时间继续运行。
示例的,终端设备的控制模块和进程模块可以均为软件模块,即通过软件程序实现控制模块和进程模块的功能。第二指示信息可以为Nack(Negative Acknowledgement)消息,以通过该Nack消息指示网络设备未接收到第一上行数据,基于此,终端设备的进程模块就可以触发在目标进程关联的第二配置授权资源上进行第一上行数据重传。
由此可见,在本申请实施例中,若第一指示信息指示允许在第四配置授权资源进行第一上行数据重传,则终端设备在目标进程对应的定时器运行期间,在目标进程关联的第四配置授权资源上进行第一上行数据重传,这些第四配置授权资源就不会因为处于空闲状态而导致配置授权资源的利用率较低,从而提高了配置授权资源的利用率。并且,由于终端设备在第四配置授权资源上重传第一上行数据,对应的,网络设备也会接收到终端设备重传的第一上行数据,这样网络设备就可以将多次接收到第一上行数据进行合并解码,从而提高了网络设备的解码成功率。
S604、若第一指示信息指示不允许在第四配置授权资源上进行第一上行数据重传,则在目标进程对应的定时器超时或者停止时,在第四配置授权资源上进行第一上行数据重传,或者,在第四配置授权资源上传输第二上行数据。
若第一指示信息指示不允许在第四配置授权资源上进行第一上行数据重传,则需要根据目标进程对应的定时器的类型确定在定时器超时或者停止时,在第四配置授权资源上进行新的第二上行数据的传输,或者在第四配置授权资源上进行第一上行数据的重传。
若目标进程对应的定时器为CG timer定时器,则在该CG timer定时器超时或者停止时,终端设备在第四配置授权资源上进行新的第二上行数据的传输;若目标进程对应的定时器为CG retransmission timer定时器,则在该CG retransmission timer超时或者停止时,终端设备在第四配置授权资源上进行第一上行数据重传。
需要说明的是,在执行完S602之后,只需要根据S602中的判断结果执行S603或S604中的任一个,即S603和S604不能同时执行,此外,S603和S604之间并无先后顺序。
基于上述实施例所示的上传数据的重传方法,可对上行授权接收的协议修改如下:
对于每个服务小区和每个上行链路配置授权,若已配置并激活,MAC实体将会执行:
1>if上行链路配置授权的物理上行共享信道(Physical Uplink Shared Channel,PUSCH简称)持续时间与物理下行控制信道(Physical Downlink Control Channel,简称PDCCH)上接收的上行链路资源的PUSCH持续时间或该服务小区的随机接入响应中的PUSCH持续时间不重叠;
2>将HARQ进程ID设置为与该PUSCH持续时间相关联的HARQ进程ID;
2>if HARQ进程ID关联的CG定时器未运行;
3>则认为HARQ进程的新数据指示符(New Date Indicator,NDI)已经被翻转;
3>将上行链路配置授权和关联的HARQ信息传递给HARQ实体。
2>else:
3>if UE被配置为在配置授权定时器运行期间,允许在配置授权中触发重传;
4>则认为HARQ进程的NDI位未被翻转;
4>将上行链路配置授权和关联的HARQ信息传递给HARQ实体。
基于上述实施例所示的上传数据的重传方法,可对HARQ实体的协议修改如下:
2>else:
3>if在PDCCH接收到的上行链路资源被寻址到配置调度小区无线网络临时标识(Configured Scheduling-RadioNetworkTemporaryIdentifier,简称CS-RNTI),并且if该确认的进程HARQ缓冲器为空;or
3>if上行链路资源是所配置的上行链路资源束的一部分,并且该上行链路资源束上没有获取任何MAC PDU;or
3>if上行链路资源是所配置的上行链路资源束的一部分,并且上行链路资源的PUSCH与在该服务小区的PDCCH或随机接入响应中接收的另一上行链路资源的PUSCH重叠;
4>忽略该上行链路资源。
3>else:
4>将该上行链路资源和该传输块的HARQ信息(冗余版本)传递给已确认的HARQ进程;
4>指示已确认的HARQ进程触发重传;
4>if上行链路资源被寻址到CS-RNTI,且UE被配置为配置授权定时器运行期间,不允许在配置授权中触发重传;or
4>if上行链路资源被寻址到C-RNTI,且已确认的HARQ进程被配置用于上行链路配置授权;
5>当执行传输时,若相应的HARQ进程已配置CG timer,则启动或者重启该CG定时器。
