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，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。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
本申请实施例提到的网络设备可以是与终端设备(或称为通信终端、终端)通信的设备。网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是新无线系统中的基站(gNB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
本申请实施例提到的终端设备包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)版本14(Rel-14)中，对车联网技术(Vehicle to Everything，V2X)定义了两种传输模式，即如图1所示的模式3和模式4。
模式3：车载终端的传输资源是由基站分配的，车载终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以通过下行链路(Downlink，DL)为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
模式4：车载终端采用侦听(sensing)+预留(reservation)的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合，终端从该集合中随机选取一个资源进行数据的传输。由于车联网系统中的业务具有周期性特征，因此终端通常采用半静态传输的方式，即终端选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。终端会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。
在LTE的车联网系统中，侧行链路传输的数据可以采用侧行控制信息(Sidelink Control Information，SCI)+数据的传输方式，其中侧行控制信息中携带的是用于解调数据所需的信息，如调制与编码策略(Modulation and Coding Scheme，MCS)、时频资源分配信息、优先级信息等，接收端终端通过检测侧行控制信息获得数据的时频资源位置，并且在相应的时频资源上对数据进行检测。侧行控制信息可以载在物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)上，数据可以承载在物理侧行共享信道 (Physical Sidelink Shared Channel，PSSCH)上，通过预配置或者网络配置PSCCH的资源池以及PSSCH的资源池，发送端终端在相应的资源池中分别发送PSCCH和PSSCH，接收端终端首先在PSCCH的资源池中盲检测PSCCH，根据PSCCH携带的SCI中的指示信息，到PSSCH资源池中相应的时频资源上检测该SCI对应的PSSCH。
在新无线-车辆网(New Radio-Vehicle to Everything，NR-V2X)中，可以支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X系统中，可以引入多种传输模式，模式1和模式2，其中，模式1可以是网络为终端分配传输资源(类似于LTE-V2X中的模式3)，模式2可以是终端选取传输资源。
NR-V2X可以支持各种传输方式，如单播(unicast)、组播(groupcast)、广播(broadcast)等。
在NR-V2X中，为了提高传输可靠性，即，接收端终端根据检测的PSCCH或PSSCH，向发送端终端或网络设备发送反馈信息，发送端终端或网络设备根据接收到的反馈信息决定是否需要向接收端终端重传数据。
例如，如图2所示，UE1向UE2发送侧行数据，UE2根据数据是否正确接收，向UE1发送反馈信息(HARQ ACK或NACK)，UE1根据接收到的反馈信息决定是否需要进行数据重传。
在NR-V2X的单播，组播或广播中，如果侧行链路的传输资源是由网络设备分配的(即上述传输模式1)，此时网络设备可以为侧行链路传输分配数据传输资源和反馈资源。接收端终端针对侧行链路的反馈信息可以存在如图3所述的两种方式，其中，图3所示，发送端终端和接收端终端可以在同一个小区中或同一个基站下。
需要说明的是，本文的实施例中的侧行反馈信息反映发送端终端发送给接收端终端的侧行数据的是否被接收端终端正确接收。该侧行反馈信息可以是由接收端终端直接发送给网络设备(此时又称为上行反馈信息)；或者是由接收端终端发送给发送端终端，发送端终端再发送给网络(此时又称为上行反馈信息)
在第一种方式中，发送端终端(UE1)向网络设备(gNB)发送上行反馈信息(该上行反馈信息反映UE1发送给UE2的侧行数据是否被UE2正确接收)。网络设备为发送端终端分配用于侧行数据传输的资源，以及发送端终端向网络设备发送上行反馈信息的上行反馈资源；侧行链路的反馈资源(即图3(a)中UE2向UE1发送侧行反馈信息所使用的资源)可以是由网络设备分配，或者是根据侧行数据的传输资源隐式确定的(例如，反馈资源在侧行数据传输资源的下一个时隙，占据该时隙的最后一个时域符号，反馈资源的频域资源和侧行数据的频域资源一致)。发送端终端在网络设备分配的资源上向接收端终端(UE2)发送侧行数据，接收端终端根据侧行数据的接收状态，在侧行链路上向发送端终端发送该侧行数据的侧行反馈信息，发送端终端在网络分配的上行反馈资源上向网络发送上行反馈信息。
在第二种实现方式中，接收端终端(UE2)向网络设备发送上行反馈信息(该上行反馈信息反映UE1发送给UE2的侧行数据是否被UE2正确接收)。网络设备为发送端终端分配用于侧行数据传输的资源，网络设备为接收端终端分配用于发送上行反馈信息的资源。发送端终端在网络设备分配的资源上向接收端终端发送侧行数据，接收端终端根据该侧行数据的接收状态，在上行反馈资源上向网络设备发送上行反馈信息。
在第一种实现方式中，侧行反馈信息可以先发送给发送端终端，发送端终端再发送给网络设备，会导致时延较大；在第二种方式中，侧行反馈信息直接由接收端终端发送给网络设备，但是如果发送端终端和接收端终端在不同的网络中，即发送端终端和接收端终端属于不同的小区，此时，接收端终端和发送端终端的基站不是同一基站，接收端终端无法直接将侧行反馈信息(也即上行反馈信息)发送给发送端终端所在的网络。或 者，当接收端终端处于小区覆盖范围外，接收端终端无法向网络发送侧行反馈信息。
为此，本申请实施例中，提供了以下方法100-300以解决该问题，在方法100-300中，可以由网络设备或发送端终端确定由接收端终端还是发送端终端来向网络设备发送指示侧行信道的接收结果的指示信息，从而可以灵活选择需要发送该指示信息的终端，以提升通信性能。
本申请实施例中提到的发送端终端可以是指在侧行链路通信中用于发送侧行信道(例如，PSCCH或PSSCH)的终端，接收端终端可以是指在侧行链路的通信中用于接收该侧行信道的终端。

应理解，在本申请实施例中，在由网络设备发送第一信息的情况下，第一信息与配置用于发送第二信息的资源的信息也可以是独立存在，也即由不同的比特位来承载。
例如，独立存在于同一条信令中，或者，独立存在于不同条的信令中。此处提到的信令可以是下行控制信息(Downlink Control Information，DCI)信令、无线资源控制(Radio Resource Control，RRC)信令或广播信令中。其中，该DCI信令可以是公共DCI，组公共DCI，也可以是终端专有DCI。
可选地，在本申请实施例中，所述网络设备发送以下信息中的至少一种信息：
指示所述发送端终端或所述接收端终端发送所述第二信息所采用的资源的信息、
指示所述发送端终端传输所述侧行信道所采用的资源的信息、
指示所述接收端终端向所述发送端终端发送所述侧行信道对应的反馈信息(可以称 为侧行反馈信息)的资源的信息。
可选地，在本申请实施例中，网络设备可以向需要发送第二信息的终端配置用于发送第二信息所采用的资源。其中，该配置信息可以承载于广播信令、RRC信令或DCI信令中，其中，该DCI信令可以是公共DCI，组公共DCI，也可以是终端专有DCI。
其中，如果需要发送第二信息的终端为发送端终端，则网络设备向发送端终端分配的用于传输第二信息的资源可以是根据以下至少一种确定的：
网络设备为发送端终端分配的传输侧行信道的传输资源、接收端终端的处理时延、接收端终端向发送端终端发送侧行反馈信息的传输资源、发送端终端的处理时延。图7示例了各个传输资源之间的时域关系，其中，图7所示的UE1为发送端终端，UE2为接收端终端。

可选地，在本申请实施例中，网络设备可以向发送端终端发送指示所述发送端终端传输所述侧行信道所采用的资源的信息，也即网络设备可以向终端设备配置传输侧行信道所采用的资源。其中，该配置信息可以承载于广播信令、RRC信令或DCI信令中，其中，该DCI信令可以是公共DCI，也可以是终端专有DCI。而对于接收端终端而言，需要在哪些资源上接收侧行信道，则可以由网络设备通知，也可以由发送端通知。
或者，在本申请实施例中，网络设备也可以不向发送端发送指示所述发送端终端传输所述侧行信道所采用的资源的信息。
在该种情况下，传输侧行信道所采用的资源可以根据第二信息所占用的资源和/或接收端终端向发送端终端发送的针对该侧行信道的侧行反馈信息所占用的资源确定。
或者，在本申请实施例中，网络设备也可以向接收端终端发送指示所述发送端终端传输所述侧行信道所采用的资源的信息。该种情况，可以适用于发送端终端不位于网络设备的覆盖范围内，或者发送端终端与网络设备之间的链路质量较差的情况下。

或者，在本申请实施例中，网络设备也可以不向接收端终端发送指示所述接收端终端向所述发送端终端传输所述侧行信道对应的侧行反馈信息所采用的资源的信息。
在该种情况下，接收端终端向发送端终端传输侧行信道对应的侧行反馈信息所采用的资源可以根据第二信息所占用的资源和/或发送端终端向接收端终端发送的侧行信道所占用的资源确定。
例如，接收端终端在时隙n接收发送端终端发送的侧行信道(PSCCH或PSSCH)， 接收端终端则需要在时隙n+k向发送端终端发送侧行反馈信息，该侧行反馈信息的频域资源的起始位置和侧行信道的频域资源的起始位置相同，或者是有对应关系；该侧行反馈信息的频域长度和侧行信道的频域长度相同，或者是固定数目的物理资源块(Physical Resource Block，PRB)或子带。其中，参数k可以是协议预定义或者网络配置，或者由其他终端指示的，该终端可以是发送端终端或者是发送端终端和接收端终端所在终端组的组头终端。

例如，指示所述发送端终端传输所述侧行信道所采用的资源的信息和指示所述发送端终端发送所述第二信息所采用的资源的信息承载于同一信令中，例如，同一下行控制信息DCI信令中。
例如，网络设备通过RRC信令向发送端终端配置多个物理上行控制信道(Physical Uplink Control Channel，PUCCH)的资源，网络通过DCI向发送端终端分配传输侧行信道的传输资源，同时，在该DCI中包括PUCCH的一个索引，用于指示发送端终端通过该PUCCH向网络设备发送上述第二信息。

图8示出了一种网络设备、发送端终端和接收端终端如何发送上述提到的信道或信息的方式。如图8所示，gNB可以向UE1分配侧行信道的传输资源和上行反馈信息的传输资源，UE1可以根据侧行信道的传输资源，向UE2发送侧行信道，UE2向UE1发送侧行反馈信息，UE1根据网络配置的资源发送上行反馈信息。
图9示出了一种网络设备、发送端终端和接收端终端如何发送上述提到的信道或信息的方式。如图9所示，gNB可以向UE1分配侧行信道的传输资源，和向UE2分配上行反馈信息的传输资源，UE1可以根据侧行信道的传输资源，向UE2发送侧行信道，UE2根据网络配置的资源发送上行反馈信息。
可选地，在本申请实施例中，上述发送端终端向接收端终端发送的侧行信道可以是PSCCH或PSSCH，以及接收端终端向发送端终端发送的侧行反馈信息可以是混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)肯定确认(Acknowledgement，ACK)或HARQ否定确认(Negative ACKnowledgment，NACK)。
可选地，本申请实施例中的第二信息可以承载于PUSCH或PUCCH中。
可选地，在本申请实施例中，第二信息可以是针对侧行传输信道的反馈信息(也可以称为上行反馈信息)，也可以是调度请求。
可选地，在本申请实施例中，在由发送端终端发送第二信息的情况下，接收端终端 可以向发送端终端发送侧行信道的侧行反馈信息，则发送端终端可以根据侧行反馈信息，向网络设备发送第二信息。
在一种实现方式中，在侧行反馈信息为HARQ NACK的情况下，发送端终端也可以向网络设备发送NACK。
在该种情况下，网络设备可以向所述发送端终端发送第五信息，所述第五信息指示用于重传从所述发送端终端到所述接收端终端的侧行信道的资源。发送端可以利用该第五信息指示的重传资源重传侧行信道。
在另一种实现方式中，在接收端终端向发送端终端发送的侧行反馈信息为DTX的情况下，发送端终端也可以向网络设备发送NACK。
在该种情况下，网络设备可以向所述发送端终端发送第六信息，所述第六信息指示用于重传从所述发送端终端到所述接收端终端的侧行信道的资源。发送端可以利用该第六信息指示的重传资源重传侧行信道。
或者，在本申请实施例中，在发送端终端向网络设备发送NACK之前，网络设备已向发送端终端配置用于重传该侧行信道的资源(例如，在配置初传资源的时候同时配置重传资源)，则网络设备无需向发送端终端发送该第五信息或第六信息。而发送端终端可以利用该已分配的重传资源重传侧行信道。
在一种实现方式中，在侧行反馈信息为ACK的情况下，发送端终端也可以向网络设备发送ACK，或者，由于ACK代表着侧行信道已经发送成功，则发送端终端可以向网络设备发送调度请求，具体可以在存在待传输的数据的情况下，发送端终端可以向网络设备发送调度请求，调度请求可以代表着前一次的侧行信道传输成功，以请求新的资源用于传输新的数据。
在第二信息指示侧行信道已经发送成功的情况(可以是ACK，也可以是调度请求)下，如果网络设备已经向发送端终端分配该侧行信道的重传资源，则网络设备可以释放、重新分配或重新调度已为所述发送端终端分配的用于重传从所述发送端终端到所述接收端终端的侧行信道的资源。
可选地，在本申请实施例中，在由接收端终端发送第二信息的情况下，接收端终端可以向发送端终端发送侧行反馈信息。
该种实现方式中，如果侧行反馈信息是NACK，则发送端终端可以等待网络设备为发送端终端发送的第七信息，该第七信息用于指示侧行信道的重传资源。
或者，如果侧行反馈信息是NACK，且网络设备已经为发送端终端分配用于重传侧行信道的重传资源，则可以利用该重传资源，重传侧行信道。
如果侧行反馈信息是ACK，则发送端终端可以在存在待传输的数据时，向网络设备发送调度请求，用于请求新的资源。
以及，如果侧行反馈信息是ACK，如果网络设备已经为发送端终端分配用于重传侧行信道的重传资源，则可以释放该重传资源。
可选地，在本申请实施例中，在由接收端终端发送第二信息的情况下，接收端终端可以不向发送端终端发送侧行反馈信息。
可选地，在本申请实施例中，网络设备决定是由发送端终端还是由接收端终端发送第二信息，可以是基于以下因素确定的：
发送端终端的网络覆盖信息、接收端终端的网络覆盖信息、接收端终端的处理时延信息、发送端终端的处理时延信息、接收端终端的能力信息、发送端终端的能力信息、发送端终端与接收端终端之间的链路质量、发送端终端待传输数据的属性信息，该属性信息可选地可以包括：可靠性信息，时延信息，优先级信息，传输距离或通信距离信息。该属性信息可以QoS信息。
在以上因素中，发送端终端的网络覆盖信息可以指示发送端终端是否属于网络设备对应的小区的覆盖范围内，以及接收端终端的网络覆盖信息可以指示接收端终端是否属 于网络设备对应的小区的覆盖范围内，由此可以根据接收端终端和/或发送端终端是否位于小区覆盖范围内，确定发送第二信息的终端，其中，通常只有处于覆盖范围内的终端才可以向网络设备发送第二信息。当接收端终端在小区覆盖外，或是接收端终端和发送端终端在不同的基站下，接收端终端可以向发送端终端发送侧行反馈信息，发送端终端再向基站发送上行反馈信息；当接收端终端和发送端终端在相同的基站下，接收端终端可以向基站发送上行反馈信息，其中，上行反馈信息反映发送端终端发给接收端终端的侧行信道是否被接收端终端正确接收；因此，在上述情况下，侧行信道的反馈信息都可以反馈到基站，例如，发送端终端所在的基站，使得该基站可以为发送端终端分配资源用于重传或者新数据传输。其中，本申请实施例提到的网络覆盖信息可以指终端是否处于网络设备的覆盖范围之内或者终端所属的基站或小区。
发送端终端的能力信息代表着发送端终端的处理速度等能力，可以根据发送端终端的能力信息确定是否采用发送端终端发送第二信息，如果发送端终端的能力信息代表的能力较强，可以由发送端终端发送第二信息。
接收端终端的能力信息代表着接收端终端的处理速度等能力，可以根据接收端终端的能力信息确定是否采用接收端终端发送第二信息，如果接收端终端的能力信息代表的能力较强，可以由接收端终端发送第二信息。
发送端终端的处理时延信息也可以代表着发送端终端的处理速度等能力，可以根据发送端终端的时延处理信息确定是否采用发送端终端发送第二信息，如果发送端终端的时延处理信息代表发送端终端处理速度较快，可以由发送端终端发送第二信息。
接收端终端的处理时延信息也可以代表着接收端终端的处理速度等能力，可以根据接收端终端的时延处理信息确定是否采用接收端终端发送第二信息，如果接收端终端的时延处理信息代表接收端终端处理速度较快，可以由接收端终端发送第二信息。
对于发送端终端与接收端终端之间的链路质量而言，如果该链路质量较差，则可以由接收端终端发送第二信息，这是因为如果由发送端终端发送第二信息，则需要先由接收端终端将侧行反馈信息发送给发送端终端，发送端终端再基于此发送第二信息，发送端终端与接收端终端之间的链路质量较差的情况下，接收端终端向发送端终端发送的侧行反馈信息有可能发送失败，从而导致发送端终端无法发送第二信息；相反，如果该链路质量较优，则可以由发送端终端发送第二信息。
网络设备还可以根据发送端终端待传输数据的属性信息，来确定发送端终端还是接收端终端来发送第二信息。
例如，如果该属性信息包括的时延信息表示待传输数据的时延要求较高，则为了降低处理时延，则可以采用接收端终端发送第二信息。

例如，如果待传输数据的优先级信息代表待传输数据的优先级较高，则进一步结合发送端终端与接收端终端的链路质量，发送端终端和/或接收端终端是否位于网络设备的小区覆盖范围内、发送端终端和接收端终端的处理时延和能力等，选择发送端终端或接收端终端来发送第二信息，选择的发送第二信息的终端可以保证第二信息正确和/或快速到达网络设备。

可选地，在本申请实施例中，发送端终端决定是由发送端终端还是由接收端终端发送第二信息，可以是基于以下因素确定的：
