Description

基于用户设备协作的下行传输反馈方法和相关设备 技术领域
本申请涉及通信技术领域，尤其涉及基于用户协作的下行传输反馈方法和相关设备。
背景技术
用户设备协作是未来通信系统主要支持的特性之一，其可以显著提高系统的容量以及网络的覆盖范围。具体地，基于用户协作的下行传输主要包括两个阶段：第一阶段网络设备通过下行用户网络链路发送信息到协作用户设备(英文：cooperative user equipment，简称：CUE)，第二阶段CUE将正确接收到的信号通过侧行链路(英文：side link，简称：SL)转发到目标用户设备(英文：target user equipment，简称：TUE)，其中转发方式可以有多种形式，例如放大转发、解码转发或压缩转发等。这样TUE能够在CUE的帮助下实现数据的可靠传输。
现有的传输机制下，协作设备无法对目标设备的网络设备无法对用户设备反馈的下行数据进行有效的区分。
发明内容

具体实施方式
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描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。
本申请的“/”表示“或”，本申请的“和/或”表示“和”或者“或”，例如A和/或B表示，A和B、A、B。
本申请涉及的网元为网络设备和用户设备。
本申请中，网络设备可以是任意一种具有无线收发功能的设备。包括但不限于：长期演进(英文：long term evolution，简称：LTE)中的演进型基站(NodeB、eNB或e-NodeB，evolutional Node B)，NR中的基站(gNodeB或gNB)或收发点(英文：transmission receiving point/transmission reception point,TRP)，3GPP后续演进的基站，WiFi系统中的接入节点，无线中继节点，无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，中继站、气球站等。多个基站可以支持上述提及的同一种技术的网络，也可以支持上述提及的不同技术的网络。基站可以包含一个或多个共站或非共站TRP。网络设备还可以是云无线接入网络(英文：cloud radio access network，简称：CRAN)场景下的无线控制器、集中单元(英文：centralized unit，简称：CU)，和/或分布单元(英文：distributed unit,简称：DU)。网络设备还可以是服务器，可穿戴设备、车载设备等。以下以网络设备为基站为例进行说明。所述多个网络设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端设备进行通信，也可以通过中继站与终端设备进行通信。终端设备可以与不同技术的多个基站进行通信，例如，终端设备可以与支持LTE网络的基站通信，也可以与支持5G网络的基站通信，还可以支持与LTE网络的基站以及5G网络的基站的双连接。
终端是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(英文：mobile phone)、平板电脑(Pad)、带无线收发功 能的电脑、虚拟现实(英文：virtual reality，简称：VR)终端设备、增强现实(英文：augmented reality，简称：AR)终端设备、工业控制(英文：industrial control)中的无线终端、车载终端设备、无人驾驶(英文:self driving)中的无线终端、远程医疗(英文:remote medical)中的无线终端、智能电网(英文:smart grid)中的无线终端、运输安全(英文:transportation safety)中的无线终端、智慧城市(英文:smart city)中的无线终端、智慧家庭(英文:smart home)中的无线终端、可穿戴终端设备等等。本申请的实施例对应用场景不做限定。终端有时也可以称为终端设备、用户设备、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、终端设备、无线通信设备、UE代理或UE装置等。终端也可以是固定的或者移动的。
参阅图1，图1为一种用户设备协作组(也可以称为协作组)的场景示意图，如图1所示，在上下行用户协作通信中，SUE/TUE和为其服务的若干CUE会形成一个用户协作组，例如图1中的SUE/TUE和CUE1及CUE2就形成了一个用户协作组。对于UE而言，其可以是以自身为中心的用户协作组的SUE/TUE，同时也可以是其他一个或者多个用户协作组的CUE。在同一小区中，可以存在多个不同的用户协作组。对于UE协作传输，当SUE/TUE周围有多个潜在的CUE时，网络侧或者SUE/TUE可以选择前述多个潜在CUE的一个或者多个来作为CUE。
对于上行覆盖不受限的情形，TUE可以通过上行控制信道或者上行数据信道反馈上行控制信息(英文：uplink control information,简称：UCI)，上行控制信息携带应答消息ACK/NACK以通知基站TUE是否成功接收下行数据；而对于上行覆盖受限的情形，TUE可以通过发送长格式的上行控制信息(携带ACK/NACK)以通知基站TUE是否成功接收下行数据。针对上行覆盖受限场景的下行传输的反馈问题，可通过上行协作传输的方式以提升上行覆盖，提高时频资源利用率，即TUE通过侧行资源将ACK/NACK反馈到CUE，CUE再将该ACK/NACK转发到基站处。但是基站无法区分CUE发送的ACK/NACK是CUE的ACK/NACK还是SUE/TUE的ACK/NACK。
下面介绍一种可行的解决方案。
参见图2，图2为本申请实施例提供的一种基于用户协作的下行传输反馈方法的流程示意图。本实施例方案主要应用于用户协作场景，该场景示意图可以如图1所示。

例如所述指示消息还用于指示侧行数据应答消息在所述侧行数据应答消息的资源中所使用的第三资源、侧行控制消息在所述侧行控制消息传输的资源中所使用的第四资源。
例如网络设备向所述协作组内的用户设备发送控制消息可以通过单播或组播方式向所述协作组内的用户设备发送控制消息。下面举例一种可能的组播方式，网络设备在所述协作组内组播该控制消息。
例如网络设备可以采用用户设备标识(UE ID)或用户协作组标识加扰该控制消息。下面举例一种可能的加扰方式，网络设备通过UE ID加扰该控制消息，将该控制消息单播给用户设备。下面举例另一种可选的加扰方式，网络设备通过用户协作组标识加扰该控制消息，将该控制消息组播给用户协议组。
当然上述加扰方式仅仅是为了举例说明，在实际应用中，还可以采用一些其他的可选的加扰方式。
例如所述配置消息包括以下消息的一种：预配置消息、系统信息配置消息、无线资源控制RRC公共信息配置消息。
例如所述指示消息包括以下消息的一种：下行控制信令、RRC配置消息。
参见图3，图3为本申请实施例提供的一种基于用户协作的下行传输反馈方法的流程示意图。本实施例方案主要应用于用户协作场景，该场景示意图可以如图1所示，本申请实施例中的CUE1的ACK/NACK可以为ACK1/NACK1，SUE的ACK/NACK可以为ACK2/NACK2。

303、网络设备向协作组内的用户设备发送控制消息，所述控制消息包括指示消息，所 述指示消息用于指示CUE1下行数据传输应答消息所使用的资源1以及用于转发SUE下行数据传输应答消息的资源2。
304、CUE1接收该控制消息，依据该控制消息的指示消息确定资源1和资源2；CUE1使用资源1发送ACK1/NACK1，使用资源2发送ACK2/NACK2。
305、网络设备在资源1接收到ACK1/NACK1，确定该ACK1/NACK1为CUE1的下行数据传输应答消息，在资源2接收到ACK2/NACK2，确定该ACK2/NACK2为SUE的下行数据传输应答消息。
参见图4，图4为本申请实施例提供的一种基于用户协作的下行传输反馈方法的流程示意图。本实施例方案主要应用于用户协作场景，该场景示意图可以如图1所示。
401、基站向TUE/CUE发送配置消息；通过配置消息(该配置消息可以为预配置的或者系统信息配置或无线资源控制(英文：radio resource control,简称：RRC)公共信息配置的配置信息)对TUE/CUE的侧行数据应答消息所使用的资源、侧行控制消息传输所使用的资源、用户自身下行数据应答消息所使用的资源以及用户转发其他用户下行数据应答消息所使用的资源分别进行配置，即侧行数据应答消息所使用的资源(第一物理侧行反馈信道资源(英文：physical side link feedback channel resource，简称：PSFCH Resource)，侧行控制消息传输所使用的资源(第二PSFCH Resource)，用户自身下行数据应答消息所使用的资源(第一物理上行控制信道(英文：physical uplink control channel,简称：PUCCH)资源)和用户转发其他用户下行数据应答消息所使用的资源(第二PUCCH资源)。
上述配置消息的发送方式可以为多种，例如RRC公共信息配置的配置信息可以通过广播的方式发送。
402、基站通过专用控制消息内的指示消息(例如UE专用的下行控制信令或者UE专用的RRC消息配置)对用户侧行数据应答消息所使用的具体资源(第一PSFCH资源1)、用户侧行控制消息传输所使用的具体资源(第二PSFCH资源1)、用户自身下行数据应答消息所使用的具体资源(第一PUCCH资源1)以及用户转发其他用户下行数据应答消息所使用的具体资源分别进行指示(第二PUCCH资源1)。
例如通过下行控制信令或者RRC消息中的指示域指示用户侧行数据应答消息所使用的PSFCH资源，通过下行控制信令或者RRC消息中的另一指示域指示用户侧行控制消息传输所使用的PSFCH资源，通过下行控制信令或者RRC消息中的又一指示域指示用户自身下行数据应答消息所使用的PUCCH资源，通过下行控制信令或者RRC消息中的又一指示域指示用户转发其他用户下行数据应答消息所使用的PUCCH资源，不同用户所使用的PSFCH资源或者PUCCH资源通过不同的时频资源或者不同的初始循环移位索引进行区分。
403、TUE在用户侧行控制消息传输所使用的PSFCH资源上(第二PSFCH Resource)向CUE发送下行数据的应答消息；CUE在用户侧行控制消息传输所使用的PSFCH资源上接收TUE所发送的下行数据应答消息；

406、基站在对应的PUCCH资源(第一PUCCH资源、第二PUCCH资源)上接收对应的下行数据应答消息。
例如上述专用控制消息可以通过UE ID加扰的方式实现对不同用户的不同配置。对应的，用户协作组内的终端也需要采用UE ID对该专用控制消息进行解扰。上述专用控制消息可以为单播消息，即每个UE单独使用的一个控制消息。
本申请实施例提供的一种基于用户协作的下行传输反馈方法的流程示意图。本实施例方案主要应用于用户协作场景，该场景示意图可以如图1所示。本实施例与如图4所示实施例不同在于，基站通过统一的控制消息内的指示消息对用户侧行数据应答消息所使用的具体资源、用户侧行控制消息传输所使用的具体资源，基站通过专用的控制消息内的指示消息对用户自身下行数据应答消息所使用的具体资源以及用户转发其他用户下行数据应答消息所使用的具体资源分别进行指示。
例如统一的控制消息可以为用户协作组内的组播控制消息，该统一控制消息可以采用用户协作组的标识进行加扰。对应的，用户协作组内的终端也需要采用用户协作组的标识对该统一控制消息进行解扰。上述统一控制消息可以为一个用户协作组统一使用的控制消息。
