Description

一种确定HARQ反馈资源的方法、装置及系统 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种确定混合自动重传请求(hybridautomatic repeat request，HARQ)反馈资源的方法、装置及系统。
背景技术
在车联网(vehicle to everything，V2X)通信系统中，发送端可以与接收端通过侧链路(sidelink)相互通信，如：发送端可以通过sidelink与一个接收端进行单播通信，也可以通过sidelink与多个接收端进行组播通信。在发送端与接收端通过sidelink进行单播通信或者组播通信时，为了保证通信质量和系统吞吐量，引入了HARQ技术。HARQ技术的工作原理为：发送端向接收端发送数据包，接收端接收到发送端发送的数据包，检测接收到的数据包是否出错，若无错，接收端在HARQ反馈资源(如：物理侧链路反馈信道(physical sidelink feedback channel，PSFCH))上向发送端发送一个肯定的确认(acknowledge，ACK)，发送端接收到ACK后，接着发送下一个数据包；若出错，则接收端在HARQ反馈资源上向发送端发送一个否定的确认(non-acknowledge，NACK)，发送端接收到NACK后，重新发送相同的数据包。
目前，接收端可以采用下述两种方式获取其HARQ反馈资源，并在获取的HARQ反馈资源上发送HARQ信息。第一种方式：接收基站为其确定的用于传输HARQ信息(ACK或者NACK)的HAQR反馈资源，在HARQ反馈资源上向发送端发送HARQ信息；第二种方式：接收发送端为其确定的HAQR反馈资源，在HARQ反馈资源上向发送端发送HARQ信息。其中，在第二种实现方式中，发送端如何为接收端确定HARQ反馈资源尚需讨论。

具体实施方式
下面结合说明书附图对本申请实施例的实施方式进行详细描述。
本申请实施例提供的确定HARQ反馈资源的方法可用于支持V2X通信的任一通信系统，该通信系统可以为第三代合作伙伴计划(3rd generation partnership project，3GPP)通信系统，例如，长期演进(long term evolution，LTE)系统，又可以为第五代(5th generation，5G)移动通信系统或者新空口(new radio，NR)系统，也可以为非3GPP通信系统，不予限制。下面以图1为例，对本申请实施例提供的方法进行描述。
图1为本申请实施例提供的一种通信系统的架构示意图，如图1所示，该通信系统可以包括多个终端设备(如图1所示的终端设备1、终端设备2、终端设备3、终端设备4、终端设备5)、接入网设备、核心网以及数据网络(data network，DN)。核心网可以包括但不限于接入和移动性管理功能(access and mobility management function，AMF)、V2X控制功能(V2X control function，V2XCF)、策略控制功能(policy control function，PCF)、会话管理功能(session management function，SMF)、用户面功能(user plane function，UPF)等。DN可以包括V2X应用服务器(application service，APP service)。其中，核心网和DN中包括的网元的功能可以参照现有技术中所述，不再赘述。
其中，图1中终端设备还可以称为用户设备(user equipment，UE)或者终端(terminal)，包括但不限于车载终端设备、手机(mobile phone)、平板电脑或带无线收发功能的电脑、智能加油站、智能信号灯等等。在图1所示系统中，终端设备可以位于接入网设备的覆盖范围内，接受接入网设备为其提供的服务；也可以位于接入网设备的覆盖范围外。终端设备可以通过无线接口(如Uu口)与接入网设备交互，继而通过接入网设备接入网络，如图1所示，终端设备1、终端设备5可以通过Uu口与接入网设备交互，通过接入网设备接入网络；终端设备也可以通过直连链路(如：侧行链路(sidelink))与其周围的其他终端设备进行V2X通信。例如，如图1所示，终端设备1可以通过多播方式向其周围的终端设备2、终端设备3、终端设备4发送V2X应用的数据，也可以通过单播方式向某个特定终端设备(如：终端设备2或者终端设备3或者终端设备4)发送V2X应用的数据。
在终端设备与其他终端设备进行V2X通信的过程中，需要采用下述两种模式为其分配用于V2X通信的资源：一种是model 1，由接入网设备为终端设备分配用于V2X通信的资源，二种是model 2，由终端设备决定用于V2X通信的资源，以便终端设备在分配的资源上与其他终端设备进行V2X通信。其中，为终端设备的资源可以包括用于承载HARQ信息的HARQ反馈资源，终端设备可以在分配的资源上反馈通过sidelink传输的数据所对应HARQ信息等。需要说明的是，若进行V2X通信的终端设备未处于接入网设备的覆盖范围内，则接入网设备将无法为该终端设备提供服务，无法采用model 1为终端设备分配用于V2X通信的资源，只能采用model 2为终端设备分配用于V2X通信的资源。
在model 2下，由终端设备决定用于V2X通信的资源可以包括：由发送数据的终端设备确定接收数据的终端设备的资源，或者，由接收数据的终端设备自己确定资源。本申请实施例仅以model 2下，由发送数据的终端设备(或者称为发送端)如何确定接收数据的终端设备(或者称为接收端)的HARQ反馈资源为例进行说明，发送端为接收端确定其他类型的资源的过程可参照本申请实施例所述。如：

需要说明的是，图1仅为示例性附图，图1包括的设备的数量不受限制，且除图1所示设备之外，该通信架构还可以包括其他设备。此外，图1中各个设备的名称不受限制，除图1所示名称之外，各个设备还可以命名为其他名称，不予限制。

其中，接收端的HARQ反馈资源可以用于承载发送端与接收端之间传输的数据对应的HARQ信息，或者，可以描述为接收端的HARQ反馈资源为承载发送端与接收端之间传输的数据对应的HARQ信息的时频资源或者时域资源，或者，可以描述为接收端的HARQ反馈资源为接收端的物理侧链路反馈信道(physical sidelink feedback channel，PSFCH)资源。HARQ信息可以为ACK信息或者NACK信息；当接收端正确接收到发送端发送的数据时，HARQ信息为ACK信息，当接收端未正确接收到发送端发送的数据时，HARQ信息为NACK信息或者不连续发送(discontinuous transmission，DTX)信息。
其中，发送端的处理能力信息可以用于指示接收端接收发送端发送的数据到向发送端发送与数据对应的HARQ信息的处理时间；还可以用于指示接收端接收发送端发送的数据到向发送端发送与数据对应的HARQ信息的处理能力等级，不同接收端的处理能力等级可以不同，也可以相同。本申请实施例中，可以存在多种处理能力等级，处理能力等级可以为数字表示，如：可以处理能力等级分为level 1、level  2、level 3三个等级，处理能力等级高的终端设备的处理能力较强，处理能力等级低的终端设备的处理能力较弱。
示例性的，发送端可以接收发送端发送的无线资源控制(radio resource control，RRC)消息，该RRC消息中携带接收端的处理能力信息，发送端可以从接收端发送的RRC消息中获取接收端的处理能力信息。例如，假设终端设备1向终端设备2发送V2X应用的数据，终端设备1作为发送端，终端设备2作为接收端，终端设备2接收到终端设备1发送的V2X应用的数据到终端设备2向终端设备1发送HARQ信息的处理时间为2个时隙，其处理能力等级为level 2，则终端设备2可以将用于表示“2个时隙”的信息流作为终端设备2的处理能力信息，将用于表示“2个时隙”的信息流携带在RRC消息中发送给终端设备1，或者，终端设备2可以将用于表示“level 2”的信息流作为终端设备2的处理能力信息发送给终端设备1，不予限制。
其中，发送端与接收端之间传输的数据可以分为多种类型，不同类型的数据对应的优先级可以是不同的。示例性的，发送端可以根据数据的服务质量(quanlity of service，QoS)要求确定数据的优先级，QoS要求可以包括传输速率、传输时延、传输容量等，数据的QoS要求越高，数据的优先级越大，反之，数据的QoS要求越低，数据的优先级越小。例如：数据1要求低时延、高传输速率，而数据2则对时延要求不高，且要求低传输速率，则数据1的优先级大于数据2的优先级。
本申请实施例中，发送端根据接收端的处理能力信息和/或发送端与接收端之间传输的数据的优先级，确定接收端的HARQ反馈资源可以包括下述三种情况：一、发送端根据接收端的处理能力信息确定接收端的HARQ反馈资源；二、发送端根据发送端与接收端之间传输的数据的优先级确定接收端的HARQ反馈资源；三、发送端根据接收端的处理能力信息和发送端与接收端之间传输的数据的优先级确定接收端的HARQ反馈资源。具体的，这三种情况的实现过程可参照下述。
步骤302：发送端向接收端发送指示信息。
其中，指示信息可以用于指示步骤301中发送端确定的接收端的HARQ反馈资源。示例性的，该指示信息可以为接收端的HARQ反馈资源的标识或者索引值。
例如，若接收端的HARQ反馈资源为第n+4个时隙，则发送端可以将n+4作为指示信息发送给接收端，n为大于或等于0的正整数。
基于图3所示方法，发送端可以根据接收端的处理能力，或者，发送端向接收端发送的数据的优先级，或者，接收端的处理能力以及发送端与接收端间传输的数据的优先级确定用于接收端反馈HARQ信息的资源，以便接收端在发送端确定的资源上反馈HARQ信息，上述实施例提供的方法为发送端如何确定接收端的HARQ反馈资源提供了可行性方案，解决了现有技术中发送端无法确定接收端的HARQ反馈资源的问题。
在一些实施例中，图3所示方法中，发送端根据接收端的处理能力信息确定接收端的HARQ反馈资源可以包括下述两种示例：
示例一，采用接收端接收发送端发送的数据到向发送端发送与数据对应的HARQ信息的处理时间作为接收端的处理能力信息，以接收端的处理时间表示接收端的处理能力，将大于或等于接收端的处理时间的时频资源确定为接收端的HARQ反馈资源，即接收端的HARQ反馈资源大于或等于接收端的处理时间，以保证接收端在其生成HARQ信息之后，在确定的HARQ反馈资源上向发送端反馈HARQ信息，避免接收端因处理能力不足，导致无法在确定的HARQ反馈资源上反馈HARQ信息的问题。
其中，接收端的处理时间可以以子帧为单位，或者，以时隙为单位，或者，以符号(symbol)为单位，或者，以毫秒(ms)或者秒(s)为单位，不予限制。
需要说明的是，在示例一中，接收端的处理时间越长，表示该接收端的处理能力越弱，发送端为接收端配置的HARQ反馈资源距离接收端接收数据的资源位置越远，反之，接收端的处理时间越短，表示该接收端的处理能力较强，发送端为接收端配置的HARQ反馈资源距离接收端接收数据的资源位置越近。可选的，若接收端包括终端组，终端组包括第一终端设备和第二终端设备，且第一终端设备的处理时间比第二终端设备的处理时间长，则第一终端设备的HARQ反馈资源与第一终端设备接收到第一数据的资源位置的时间间隔可以小于第二终端设备的HARQ反馈资源与第二终端设备接收到第二数据的资源位置的时间间隔。
例如，以终端设备1向终端设备2、终端设备3发送V2X应用的数据，终端设备1作为发送端，终端设备2、终端设备3作为接收端为例，若终端设备2的处理时间为2个时隙，终端设备3的处理时间为3个时隙，终端设备1在第n个时隙上向终端设备2、终端设备3发送V2X应用的数据，终端设备2、终端设备3在第n个时隙接收V2X应用的数据，则终端设备1为终端设备2确定的HARQ反馈资源可以为第n+2个时隙，或者，第n+2个时隙之后的任一时隙，如：第n+3个时隙或者第n+4个时隙等等，不可以是第n+2个时隙之前的任一时隙(如：第n+1个时隙等)，因在第n+2个时隙之前，终端设备1还未生成与V2X应用的数据对应的HARQ信息，无法向终端设备1反馈HARQ信息，若终端设备1为终端设备2确定的HARQ反馈资源为第n+2个时隙之前的时隙，则会因终端设备2的处理能力不足，导致终端设备2无法在规定的HARQ反馈资源上反馈HARQ信息。同理，终端设备1为终端设备3确定的HARQ反馈资源可以为第n+3个时隙，或者，第n+3个时隙之后的任一时隙。
又例如，若终端设备2的处理时间为4ms，则终端设备1为终端设备2确定的HARQ反馈资源与终端设备2接收到数据的时间间隔应该等于或大于4ms，不可以小于4ms，若终端设备1为终端设备2确定的HARQ反馈资源与终端设备2接收到数据的时间间隔大于4ms，如：为3ms，那么会因为终端设备2的处理能力不足从而导致终端设备2无法在规定的HARQ反馈资源上反馈HARQ信息。同理，若终端设备3的处理时间为5ms，则终端设备1为终端设备3配置的HARQ反馈资源与终端设备3接收到数据的时间间隔应该等于或大于5ms。
示例二，接收端的处理能力等级与资源池间存在对应关系，资源池可以包括一个或者多个时频资源；发送端可以根据接收端的处理能力信息，确定接收端的处理能力等级；根据接收端的处理能力等级以及对应关系，从接收端的处理能力等级对应的资源池中确定接收端的HARQ反馈资源，如：可以选择该资源池中的任一时频资源作为接收端的HARQ反馈资源。
其中，资源池以及接收端的处理能力等级与资源池的对应关系可以由接入网设备预先配置给发送端。资源池中包括的时频资源均可以作为接收端的HARQ反馈资源，即接收端可以在其处理能力等级所对应的资源池中的任一时频资源上反馈HARQ信息。
需要说明的是，本申请实施例中，各个资源池的长度相同或者不同。各个资源池的起始边界可以不固定，资源池的起始边界可以与发送端发送数据的资源位置有关。示例性的，资源池的起始边界可以大于或等于发送端发送数据的资源位置，如：若发送端在子帧n发送数据，则资源池的起始边界可以为子帧n，也可以为子帧n之后的任一子帧，如：子帧n+k，k为正整数。
例如，存在三个处理能力等级：level 1、level 2以及level3，各个处理能力等级对应的资源池如如图4所示，若终端设备1向终端设备2发送数据，终端设备2的处理能力等级为level 1，则终端设备1可以从资源池1中选择出HARQ反馈资源1作为终端设备2的HARQ反馈资源，若终端设备2的处理能力等级为level 2，则终端设备1可以从资源池2中选择出HARQ反馈资源2作为终端设备2的HARQ反馈资源；若终端设备2的处理能力等级为level 3，则终端设备1可以从资源池3中选择出HARQ反 馈资源3作为终端设备2的HARQ反馈资源。
在一些实施例中，图3所示方法中，除根据接收端的处理能力信息确定接收端的HARQ信息之外，发送端还可以根据其他信息确定接收端的HARQ反馈资源，如：发送端还可以根据接收端的数据的优先级确定接收端的HARQ反馈资源，数据的优先级越高，确定的HARQ反馈资源越靠近接收端接收到数据的资源位置，反之，则距离接收端接收到数据的资源位置较远。下面以接收端可以包括终端组，终端组可以包括至少两个终端设备。示例性的，终端组可以包括第一终端设备和第二终端设备，发送端与第一终端设备间传输的数据为第一数据，发送端与第二终端设备间传输的数据为第二数据为例，对发送端根据接收端的数据的优先级确定接收端的HARQ反馈资源的过程进行描述：
当第一数据的优先级大于第二数据的优先级时，表示第一数据的QoS要求比第二数据的QoS要求高，应该优先反馈第一数据对应的HARQ信息，第一终端设备的HARQ反馈资源与第一终端设备接收到第一数据的资源位置的时间间隔小于第二终端设备的HARQ反馈资源与第二终端设备接收到第二数据的资源位置的时间间隔；
反之，当第一数据的优先级小于第二数据的优先级时，表示第二数据的QoS要求比第一数据的QoS要求高，应该优先反馈第二数据对应的HARQ信息，第一终端设备的HARQ反馈资源与第一终端设备接收到第一数据的资源位置的时间间隔大于第二终端设备的HARQ反馈资源与第二终端设备接收到第二数据的资源位置的时间间隔。
例如，终端设备1向终端设备2发送文字业务的数据，终端设备1向终端设备3发送视频业务的数据，因文字业务的数据的优先级低于视频业务的数据的优先级，则如图5所示，可以将时域资源靠前的HARQ反馈资源1配置给终端设备3，将时域资源靠后的HARQ反馈资源配置给终端设备2。
需要说明的是，在该实现方式中，为了避免因接收端处理能力不足导致的接收端无法在发送端为其配置的HARQ反馈资源上发送HARQ信息的问题，发送端根据数据的优先级为接收端配置的HARQ反馈资源需要大于或等于接收端的处理时间。
在一些实施例中，图3所示方法中，除根据接收端的处理能力信息或者根据接收端与发送端间传输的数据的优先级确定接收端的HARQ反馈资源之外，发送端还可以结合接收端的处理能力信息和根据接收端与发送端间传输的数据的优先级确定接收端的HARQ反馈资源，如：发送端可以先根据接收端的处理能力信息确定一些时频资源，再根据接收端与发送端间传输的数据的优先级从确定的时频资源中选择出接收端的HARQ反馈资源。
下面以接收端的处理能力信息用于指示接收端的处理能力等级，接收端的处理能力等级与资源池间存在对应关系，接收端包括终端组，终端组包括第一终端设备和第二终端设备，发送端与第一终端设备间传输的数据为第一数据，发送端与第二终端设备间传输的数据为第二数据为例，通过下述情况一、情况二对发送端结合接收端的处理能力信息和根据接收端与发送端间传输的数据的优先级确定接收端的HARQ反馈资源进行描述：
情况一：第一终端设备、第二终端设备的处理能力等级相同，第一终端设备的处理能力等级、第二终端设备的处理能级对应同一资源池。发送端根据第一终端设备、第二终端设备的处理能力等级以及处理能力等级与资源池间的对应关系，确定与第一终端设备的处理能力等级、第二终端设备的处理能力等级对应的资源池；再根据第一数据与第二数据的优先级，从确定的资源池中选择第一时频资源作为第一终端设备的HARQ反馈资源，选择第二时频资源作为第二终端设备的HARQ反馈资源。
其中，当第一数据的优先级大于第二数据的优先级时，第一时频资源与第一终端设备接收到第一数据的资源位置的时间间隔小于第二时频资源与第二终端设备接收到第二数据的资源位置的时间间隔。当 第一数据的优先级小于第二数据的优先级时，第一时频资源与第一终端设备接收到第一数据的资源位置的时间间隔大于第二时频资源与第二终端设备接收到第二数据的资源位置的时间间隔。
例如，以终端设备1向终端设备2发送V2X应用的数据，向终端设备3发送V2V应用的数据，向终端设备4发送V2I应用的数据，终端设备4的处理能力等级为level 1，终端设备2、终端设备3的处理能力等级为level 2，且V2X应用的数据的优先级低于V2V应用的数据的优先级，则如图6所示，终端设备1可以从资源池1中选择出HARQ反馈资源1作为终端设备4的HARQ反馈资源，从资源池2中选择终端设备2、终端设备3的HARQ反馈资源，如：终端设备1可以将资源池2中时域资源靠前的HARQ反馈资源2配置给终端设备3，将资源池2中时域资源靠后的HARQ反馈资源配置给终端设备2。
情况二：第一终端设备、第二终端设备的处理能力等级不同，第一终端设备的处理能力等级、第二终端设备的处理能级对应不同资源池；发送端根据第一终端设备的处理等级与处理能力等级与资源池间的对应关系，确定第一终端设备的处理能力等级对应的资源池，从该资源池中选择出第一终端设备的HARQ反馈资源，如：若第一数据的优先级较高，则从该资源池中选择距离第一终端设备接收数据的资源位置较近的时频资源作为第一终端设备的HARQ反馈资源，反之，若第一数据的优先级较低，则从该资源池中选择距离第一终端设备接收数据的资源位置较远的时频资源作为第一终端的HARQ反馈资源；同理，发送端根据第二终端设备的处理等级与处理能力等级与资源池间的对应关系，确定第二终端设备的处理能力等级对应的资源池，从该资源池中选择出第二终端设备的HARQ反馈资源，如：可以从该资源池中选择任一时频资源作为第二终端设备的HARQ反馈资源。
例如，level 1对应资源池1，level 2对应资源池2，假设终端设备1向终端设备2发送V2X应用的数据，向终端设备3发送V2V应用的数据，终端设备2的处理能力等级为level 1，终端设备3的处理能力等级为level 2，则终端设备1可以从资源池1中选择出终端设备2的HARQ反馈资源，从资源池2中选择终端设备3的HARQ反馈资源。若终端设备1向终端设备2发送的V2X应用的数据为文字，优先级较低，则终端设备1可以将资源池1中时域资源靠后的HARQ反馈资源配置给终端设备2，若终端设备1向终端设备发送的V2X应用的数据为视频，优先级较高，则终端设备1可以将资源池1中时域资源靠前的HARQ反馈资源配置给终端设备2。
上述情况一、情况二以接收端的处理能力信息用于指示接收端的处理能力等级为例，对发送端确定HARQ反馈资源的过程进行了描述，可以理解的是，当接收端的处理能力信息用于指示接收端的处理时间时，发送端也可以参照上述情况一、情况二确定接收端的HARQ反馈资源，如：若第一终端设备的处理时间与第二终端设备的处理时间相同，则发送端根据第一数据与第二数据的优先级确定第一终端设备的HARQ反馈资源、第二终端设备的HARQ反馈资源，当第一数据的优先级大于第二数据的优先级时，第一终端设备的HARQ反馈资源与第一终端设备接收到第一数据的资源位置的时间间隔小于第二终端设备的HARQ反馈资源与第二终端设备接收到第二数据的资源位置的时间间隔；当第一数据的优先级小于第二数据的优先级时，第一终端设备的HARQ反馈资源与第一终端设备接收到第一数据的资源位置的时间间隔大于第二终端设备的HARQ反馈资源与第二终端设备接收到第二数据的资源位置的时间间隔。
若第一终端设备的处理时间与第二终端设备的处理时间不同，则第一终端设备的HARQ反馈资源与第一终端设备接收到第一数据的资源位置的时间间隔等于或大于第一终端设备的处理时间，第二终端设备的HARQ反馈资源与第二终端设备接收到第二数据的资源位置的时间间隔等于或大于第二终端设备的处理时间；此外，若第一数据的优先级较高，则第一终端设备的HARQ反馈资源距离第一终端设备接收数据的资源位置较近，反之，若第一数据的优先级较低，则第一终端设备的HARQ反馈资源距离第一终端设备接收数据的资源位置较远。同理，若第二数据的优先级较高，则第二终端设备的HARQ反馈资源 距离第二终端设备接收数据的资源位置较近，反之，若第二数据的优先级较低，则第二终端设备的HARQ反馈资源距离第二终端设备接收数据的资源位置较远。
进一步的，在图3所示方法，所述方法还可以包括：发送端在其确定的HARQ反馈资源上接收接收端发送的HARQ信息。如此，可以保证发送端接收HARQ信息的准确性。
例如，若终端设备1为终端设备2确定的HARQ反馈资源为第n+4个时隙，则终端设备1可以在第n+4个时隙上接收终端设备2发送的HARQ信息。
