Definitions

  • Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for sending and receiving side link information.
  • LTE Long-term evolution
  • V2X Vehicle to Everything
  • the first device in LTE V2X can directly communicate with the second device through a side link (SL, sidelink).
  • the side link is a newly defined air interface for LTE V2X (that is, the air interface between V2X devices), as opposed to the usual cellular network Uu interface (that is, the air interface between network devices and terminal devices).
  • the side link can use the frequency resources of the Uu interface of the cellular network or dedicated frequency resources.
  • LTE V2X only supports broadcast services.
  • the first device can broadcast road safety information to all second devices around it.
  • the first device can transmit control information through a physical side-link control channel (PSCCH, Physical, Sidelink, Control Channel) and data information through a physical side-link data channel (PSSCH, Physical, Sidelink, Shared Channel);
  • PSCCH Physical, Sidelink, Control Channel
  • PSSCH Physical, Sidelink, Shared Channel
  • the two devices can blindly detect the side link control information (SCI, Side Link Control Information) format (such as SCI format 1).
  • SCI Side Link Control Information
  • the SCI is used to indicate the scheduled data information and is carried by the PSCCH.
  • LTE V2X does not provide confirmation information for hybrid automatic repeat request (HARQ-ACK, Hybrid Automatic Repeat Question Acknowledge, including ACK / NACK) Support for channel state information (CSI, Channel State Information) feedback / reporting.
  • HARQ-ACK Hybrid Automatic Repeat Question Acknowledge
  • CSI Channel State Information
  • New Radio (NR, New Radio) V2X is one of the current Rel-16 standardization research projects. Compared with LTE V2X, NR V2X needs to support many new scenarios and new services (for example, remote driving, autonomous driving and fleet driving, etc.), and needs to meet higher technical indicators (for example, high reliability, low latency, high Data rate, etc.).
  • NR V2X also needs to provide support for unicast services and multicast services.
  • the unicast mode is more suitable for scenarios and services that have higher data rate requirements; for example, two vehicle devices can exchange road condition information and / or video information through the unicast mode.
  • the feedback and reporting of HARQ-ACK and / or CSI are of great significance for unicast services and / or multicast services.
  • the first device may decide whether to schedule retransmission based on the feedback result of HARQ-ACK, so as to avoid possible resource waste caused by blind retransmission; or, the first device may also perform link adaptation based on CSI measurement and reporting results; For example, the first device can select the modulation and coding scheme (MCS, Modulation and Coding), precoding matrix indicator (PMI, Precoding Matrix Indicators), beam, rank, etc. that are most suitable for the current channel based on CSI, which is beneficial to Achieve high data rate transmission.
  • MCS modulation and coding scheme
  • PMI Precoding Matrix Indicators
  • LTE V2X only supports broadcast services. In view of the limited role of HARQ-ACK and / or CSI feedback for broadcast services, LTE V2X does not provide support for HARQ-ACK and / or CSI feedback and reporting. In contrast, NR V2X needs additional support for unicast and multicast services, and the feedback of HARQ-ACK and / or CSI is of greater significance to the unicast and multicast services in NR V2X. Carrying out the feedback of HARQ-ACK and / or CSI is a problem that needs to be studied and solved.

Description

边链路信息的发送和接收方法以及装置 技术领域
本发明实施例涉及通信技术领域，特别涉及一种边链路信息的发送和接收方法以及装置。
背景技术
长期演进(LTE，Long Term Evolution)的车联网(V2X，Vehicle to Everything)是一种车辆通信技术，能够实现车辆与车辆、车辆与路侧设备以及车辆与行人之间的信息交互。
LTE V2X中的第一设备可以通过边链路(SL，sidelink)与第二设备直接进行通信。边链路是为LTE V2X新定义的空中接口(即V2X设备之间的空中接口)，与通常的蜂窝网络Uu接口(即网络设备与终端设备之间的空中接口)相对。边链路可以使用蜂窝网络Uu接口的频率资源，也可以使用专用的频率资源。
LTE V2X仅支持广播业务，例如，第一设备可将道路安全信息广播给周围所有的第二设备。在边链路传输中，第一设备可以通过物理边链路控制信道(PSCCH，Physical Sidelink Control Channel)传输控制信息，通过物理边链路数据信道(PSSCH，Physical Sidelink Shared Channel)传输数据信息；第二设备可以盲检边链路控制信息(SCI，Sidelink Control Information)格式(例如SCI format 1)，SCI用来指示所调度的数据信息并由PSCCH承载。鉴于反馈信息(例如，HARQ-ACK和/或CSI)对于广播业务的作用有限，LTE V2X没有提供对混合自动重传请求确认信息(HARQ-ACK，Hybrid Automatic Repeat reQuest Acknowledge，包括ACK/NACK)和信道状态信息(CSI，Channel State Information)反馈/上报的支持。
另一方面，新无线(NR，New Radio)V2X是目前Rel-16标准化的研究项目之一。相比于LTE V2X，NR V2X需要支持诸多的新场景和新业务(例如，远程驾驶、自动驾驶和车队行驶等等)，需要满足更高的技术指标(例如，高可靠、低时延、高数据速率等等)。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发 明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现：为满足不同场景和不同业务的需求，除广播业务外，NR V2X还需要提供对单播业务和组播业务的支持。单播方式更加适用于对数据速率有较高要求的场景和业务；例如，两个车辆设备可以通过单播方式交互路况信息和/或视频信息。与广播业务的情形不同，HARQ-ACK和/或CSI的反馈和上报对于单播业务和/或组播业务具有重要意义。
例如，第一设备可以基于HARQ-ACK的反馈结果决定是否调度重传，从而可以避免盲重传可能造成的资源浪费；或者，第一设备也可以基于CSI测量和上报结果进行链路自适应；例如，第一设备可以基于CSI选择最能适应当前信道的调制和编码方案(MCS，Modulation and Coding Scheme)、预编码矩阵指示(PMI，Precoding Matrix Indicators)、波束、秩，等等，从而有利于实现高数据速率传输。
但是，LTE V2X仅支持广播业务，鉴于HARQ-ACK和/或CSI的反馈对于广播业务的作用有限，LTE V2X没有提供对HARQ-ACK和/或CSI的反馈和上报的支持。相比之下，NR V2X需要额外支持单播业务和组播业务，而HARQ-ACK和/或CSI的反馈对于NR V2X中的单播业务和组播业务具有更大意义，因此在V2X中如何进行HARQ-ACK和/或CSI的反馈是一个需要研究和解决的问题。

本发明实施例将以边链路和V2X为例进行说明，但本发明不限于此。
实施例1
本发明实施例提供一种边链路信息的发送方法，从发送设备(也可称为第二设备、目的设备)侧进行说明。其中该发送设备可以是终端设备，但本发明不限于此，例如也可以是路侧设备或者网络设备。
图2是本发明实施例的边链路信息的发送方法的一示意图，如图2所示，所述方法包括：
步骤201，第二设备接收至少一个第一设备发送的第一数据信息和/或参考信号；
步骤202，所述第二设备确定第二数据信息和/或针对所述第一数据信息和/或所述参考信号的反馈信息的优先级；
步骤203，所述第二设备根据所述优先级为所述第二数据信息和/或所述反馈信息分配功率；以及
步骤204，所述第二设备向所述至少一个第一设备发送分配功率后的所述第二数据信息和/或所述反馈信息。
值得注意的是，以上附图2仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型， 而不仅限于上述附图2的记载。
在一个实施例中，所述反馈信息可以包括如下至少之一：混合自动重传请求确认信息(HARQ-ACK；可以包括ACK/NACK)、信道状态信息(CSI)、调制和编码方案(MCS)、信道质量指示(CQI)、预编码矩阵指示(PMI)、秩指示(RI)、波束信息、参考信号接收功率(RSRP，reference signal received power)、参考信号接收质量(RSRQ，reference signal received quality)、路径损耗(pathloss/pathgain)、探测参考信号资源指示(SRI，SRS resource indicator)、参考信号资源指示(CRI，CSI-RS resource indicator)、干扰条件(interference condition)、移动信息(motion information)；但本发明不限于此，还可以包括其他的信息。
以下将以HARQ-ACK和/或CSI为例进行说明。为简单起见，HARQ-ACK和/或CSI在本文中可以记为HARQ-ACK/CSI。此外，本文中“反馈”(feedback)和“上报”(report)可以具有相同或相似的含义，反馈信息与HARQ-ACK/CSI可以具有相同或相似的含义。在表示边链路控制信息这一含义时，PSCCH和SCI可以互换，不做严格区分。
在本发明实施例中，边链路反馈信息也可以称为边链路反馈控制信息(SFCI，sidelink feedback control information)。承载反馈信息的专用物理信道可以称为物理边链路反馈控制信道(PSFCCH，Physical Sidelink Feedback Control Channel)。源设备(第一设备)向目的设备(第二设备)发送单播数据(例如通过PSCCH调度PSSCH)和/或参考信号。目的设备向源设备发送反馈信息。源标识(source ID)和目的标识(destination ID)分别用来标识源设备和目的设备，可以通过PSCCH通知给目的设备。
在本发明实施例中，目的设备还可以向源设备发送第二数据信息；即第二设备向第一设备发送的信息可以包括第二数据信息和/或反馈信息(针对第一数据信息和/或参考信号)。所述第二数据信息和所述反馈信息可以承载在PSSCH或PSFCCH中；或者，所述反馈信息可以承载在PSCCH或者PSFCCH中，而所述第二数据信息承载在PSSCH中。
图3是本发明实施例的第一设备和第二设备的示意图。如图3所示，一个或多个(至少一个)第一设备(源设备)可以向第二设备(目的设备)发送数据/参考信号(第一数据信息和/或参考信号)，而第二设备可以向第一设备发送数据/反馈信息(第 二数据信息和/或HARQ-ACK/CSI)。
例如，以HARQ-ACK为例，目的设备接收来自不同源设备的单播数据，因此需要向不同源设备发送HARQ-ACK。目的设备可能需要同时发送多于一个的反馈信息，即向多于一个源设备发送反馈信息。例如在不存在网络侧(基站)全局调度的情况下(例如LTE V2X Mode 4或NR V2X Mode 2)，V2X设备需要自行决定HARQ-ACK时序(timing)(例如源设备通过PSCCH通知目的设备何时发送HARQ-ACK)，由于各个源设备独立决定HARQ-ACK时序，因此即使在同一个载波(carrier)内，也可能出现目的设备需要在同一时刻反馈多于一个HARQ-ACK的情况。
图4是本发明实施例的反馈信息的示例图，如图4所示，针对第一数据信息(图4中使用PSCCH/PSSCH表示)的HARQ-ACK(图4中使用A/N表示)可以通过PSFCCH承载。例如，一个第一设备发送序号为#m的PSCCH/PSSCH，另外一个第一设备发送序号为#n的PSCCH/PSSCH，针对这两个PSCCH/PSSCH，第二设备在相同的时隙(slot)和不同的资源块(RB，Resource Block)上发送A/N#m和A/N#n两个反馈信息。
值得注意的是，图4仅以发送多个HARQ-ACK反馈信息为例进行说明，图4中多个反馈信息中的任一反馈信息还可以是CSI，或者是HARQ-ACK和CSI。另外，目的设备在发送HARQ-ACK/CSI反馈信息的同时，也可能有数据信息需要发送给源设备，此时可以将HARQ-ACK/CSI反馈信息连同数据信息一起通过PSSCH或PSFCCH进行发送，此时发送的信息中包括数据信息和反馈信息。
包含第二数据信息和/或反馈信息的信息可以通过PSSCH或PSFCCH发送，或者，仅包含反馈信息的信息可以通过PSFCCH或PSCCH发送。例如，图3中的目的设备可以向源设备#m发送包含第二数据信息和反馈信息的信息，同时向源设备#n发送仅包含反馈信息的信息。
HARQ-ACK/CSI还可以通过Uu接口(PUCCH或PUSCH)发送给网络设备(例如基站)，为便于表述，本发明实施例可以将通过Uu接口发送的信息称为Uu信息。例如，图3中的目的设备和源设备#m均处于基站覆盖范围内，源设备#m工作在基站调度模式(NR V2X Mode 1)，则目的设备可以将发送给源设备#m的HARQ-ACK/CSI通过Uu接口直接发送给基站；在发送该Uu信息的同时，该目的设备也可以向基站覆盖范围外的源设备#n通过PSFCCH发送反馈信息。
因此，当设备需要同时发送多个信息(可以包括数据信息和/或反馈信息)时，从承载信道上看，上述信息可以通过PSFCCH发送，或者通过PSSCH发送，或者通过PSCCH发送，或者通过Uu接口发送；从信息内容上看，任一上述信息可以仅包含HARQ-ACK，或者仅包含CSI，或者仅包含数据信息，或者同时包含HARQ-ACK和CSI，或者同时包含HARQ-ACK和数据信息，或者同时包含CSI和数据信息，或者同时包含HARQ-ACK、CSI和数据信息。
在一个实施例中，位于所述物理边链路控制信道或者所述物理边链路反馈控制信道前的一个符号被用于保护间隔(guard)和/或自动增益控制(AGC，Automatic Gain Control)。
图5是本发明实施例的承载SFCI的PSFCCH的示例图，以时隙为例，在发送SFCI的时隙内，承载SFCI的符号之前预留一个符号，用作收发(Tx/Rx)转换的保护间隔(图5中用G表示)以及AGC调整。
基于RAN4的需求，收发转换和AGC的调整时间均可以小于1个符号，因此可以仅预留1个符号用于保护周期和/或AGC；例如，该符号内的前面部分可用作收发转换的保护间隔，该符号内的后面部分可用作AGC调整。
在本发明实施例中，例如可以使用正交频分复用(OFDM，Orthogonal Frequency Division Multiplex)、单载波频分复用(SC-FDMA，Single-Carrier Frequency Division Multiple Access)或离散傅里叶变换扩展正交频分复用(DFT-s-OFDM，Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplex)等波形，因此上述符号可以为OFDM或SC-FDMA或DFT-s-OFDM等符号，以下简称为符号；但本发明不限于此。
在一个实施例中，可以根据服务质量(QoS)参数确定所述第二数据信息和/或所述反馈信息的优先级。例如，所述服务质量参数可以包括如下至少之一：数据包优先级(priority和/或PPPP，ProSe Per-Packet Priority)、时延(latency)、可靠性(reliability)、最小需要的通信距离(minimum required communication range)、数据包可靠性(PPPR，ProSe Per-Packet Reliability)、信道忙率(CBR，Channel Busy Ratio)、信道占用率(CR，Channel Occupancy Ratio)；但本发明不限于此。
QoS参数可以由网络设备或者第一设备通过信令通知给该第二设备，例如使用动态信令PSCCH、无线资源控制(RRC，Radio Resource Control)信令、介质访问控制 (MAC，Media Access Control)控制元素(CE，Control Element)、系统消息、广播消息中的至少一项；或者也可以由该第二设备的高层通知给物理层。
在本发明实施例中，层1(L1)例如包括物理层，层2(L2)例如包括MAC层、无线链路控制(RLC，Radio Link Control)层等，高于层2的层可以包括无线资源控制(RRC，Radio Resource Control)层、V2X应用层(V2X application layer)、接入层之上的层等；这里高层可以指高于层1的层。关于各协议层的具体定义可以参考相关技术。
在步骤202中，第二设备确定第二数据信息和/或所述反馈信息的优先级，例如可以包括如下至少之一：
在一个实施方式中，根据调度第二数据信息的边链路控制信息(SCI，Sidelink Control Information)所指示的服务质量参数和/或高层通知的所述第二数据信息的服务质量参数确定所述第二数据信息的优先级。
例如，数据信息的优先级由调度该数据信息的PSCCH中的数据包优先级字段(例如priority)所确定。
在一个实施方式中，根据调度所述第一数据信息的边链路控制信息所指示的服务质量参数和/或高层通知的所述第一数据信息的服务质量参数确定针对所述第一数据信息的混合自动重传请求确认信息的优先级。
例如，对于仅包含HARQ-ACK的反馈信息，其优先级取决于与HARQ-ACK关联的PSSCH/PSCCH的QoS参数。“与HARQ-ACK关联的PSSCH/PSCCH”表示HARQ-ACK是针对PSCCH调度的PSSCH的反馈。
再例如，第二设备需要同时发送多个HARQ-ACK，与HARQ-ACK相关联的PSCCH中的字段指示了数据包优先级(priority)，可以基于该字段确定HARQ-ACK的优先级，对应于较高数据包优先级的HARQ-ACK具有较高的优先级。
在一个实施方式中，根据与信道状态信息相关联的预设门限确定所述信道状态信息的优先级。
例如，可以设定优先级门限，将该优先级门限当作CSI的优先级。
在一个实施方式中，仅包含混合自动重传请求确认信息的反馈信息的优先级高于仅包含信道状态信息的优先级。
在一个实施方式中，既包含混合自动重传请求确认信息又包含信道状态信息的反 馈信息的优先级等于被包含的所述混合自动重传请求确认信息和所述信道状态信息中较高的优先级。
例如，对于同时包含HARQ-ACK和CSI的反馈信息，其优先级为HARQ-ACK和CSI中的较高优先级，例如为该HARQ-ACK的优先级。
在一个实施方式中，既包含第二数据信息又包含混合自动重传请求确认信息的第一信息的优先级等于被包含的所述第二数据信息和所述自动重传请求确认信息中较高的优先级；
例如，对于包含数据信息和HARQ-ACK的第一信息，数据信息的优先级可能高于HARQ-ACK的优先级。例如。数据信息业务比HARQ-ACK关联的数据信息业务具有更高的时延要求，此时需要优先满足更高时延需求的数据信息业务，数据信息优先级高于HARQ-ACK。因此，当数据信息的优先级高于HARQ-ACK优先级时，第一信息的优先级即为该数据信息的优先级。
在一个实施方式中，既包含第二数据信息又包含信道状态信息的第二信息的优先级等于被包含的所述第二数据信息和所述信道状态信息中较高的优先级；
例如，对于包含数据信息和CSI的第二信息，为确定数据信息与CSI的优先级高低，可以设定优先级门限；例如将该优先级门限当作CSI的优先级，当数据信息优先级高于该优先级门限时，数据信息具有比CSI更高的优先级，否则数据信息具有比CSI更低的优先级。上述优先级门限可以通过使用动态信令PSCCH、RRC信令、MAC CE、系统消息、广播消息中的至少一项进行配置，或者可以预定义。第二信息的优先级等于被包含的数据信息和CSI中较高的优先级。
在一个实施方式中，既包含第二数据信息又包含混合自动重传请求确认信息和信道状态信息的第三信息的优先级等于被包含的所述第二数据信息、所述自动重传请求确认信息和所述信道状态信息中最高的优先级。
例如，对于包含数据信息、HARQ-ACK和CSI的第三信息，该第三信息的优先级为数据信息、HARQ-ACK、CSI中最高的优先级。
在一个实施方式中，还可以对第二数据信息和/或反馈信息的优先级进行排序。
值得注意的是，以上各个实施方式仅对本发明实施例如何确定优先级进行了示例性说明，但本发明不限于此，还可以在以上各个实施方式的基础上进行适当的变型。例如，可以单独使用上述各个实施方式，也可以将以上各个实施方式中的一种或多种 结合起来。
在步骤203中，第二设备根据所述优先级为所述第二数据信息和/或所述反馈信息分配功率，例如可以包括如下至少之一：
在一个实施方式中，仅为优先级最高的所述第二数据信息和/或所述反馈信息分配功率。例如，仅对优先级为1(优先级最高)的第二数据信息和/或反馈信息(一个或多个)分配功率，而不发送其他优先级(例如优先级较低的优先级2、3等)的信息。
在一个实施方式中，按照优先级由高到低的顺序，优先为优先级较高的所述第二数据信息和/或所述反馈信息分配功率；在还有剩余功率的情况下，再为优先级较低的所述第二数据信息和/或所述反馈信息分配功率；
例如，对优先级为1(优先级最高)的第二数据信息和/或反馈信息(一个或多个)分配功率；在还有剩余功率的情况下，再为优先级2的第二数据信息和/或反馈信息(一个或多个)分配功率。对于优先级为3、4的第二数据信息和/或反馈信息(一个或多个)等，可以以此类推。
在一个实施方式中，当为所述第二数据信息和/或所述反馈信息所分配的功率小于功率控制所要求的最小功率时，不为所述第二数据信息和/或所述反馈信息分配功率或者不发送所述第二数据信息和/或所述反馈信息。
在一个实施例中，对于具有相同优先级的至少两个信息，例如不是仅包含HARQ-ACK或仅包含CSI的信息，可以通过对比内容的优先级来确定功率分配顺序。
在一个实施方式中，对于具有相同优先级的至少包含所述第二数据信息的第四信息和至少包含混合自动重传请求确认信息的第一反馈信息，优先为所述第一反馈信息分配功率；其中所述第四信息的优先级等于所述第二数据信息的优先级，所述第一反馈信息的优先级等于所述混合自动重传请求确认信息的优先级。
例如，对于具有相同优先级的信息1和信息2，如果信息1中HARQ-ACK具有最高优先级，信息2是至少包含数据信息的第四信息并且该第四信息中的数据信息具有最高优先级，即该HARQ-ACK的优先级等于该数据信息的优先级，则优先为信息1分配功率。
在一个实施方式中，对于具有相同优先级的仅包含混合自动重传请求确认信息的第二反馈信息和既包含混合自动重传请求确认信息又包含信道状态信息的第三反馈 信息，优先为所述第三反馈信息分配功率。
例如，对于具有相同优先级的信息1和信息2，信息1包含HARQ-ACK，信息2包含HARQ-ACK和CSI，因为信息2中的CSI还具有优先级，因此优先为信息2分配功率。
在一个实施方式中，对于具有相同优先级的位于主载波的所述第二数据信息和/或第四反馈信息和不位于主载波的所述第二数据信息和/或第五反馈信息，优先为位于主载波的所述第二数据信息和/或所述第四反馈信息分配功率。
例如，对于具有相同优先级的信息1和信息2，如果信息1和信息2位于同一个载波，可以任意决定信息1和信息2的功率分配顺序；如果信息1位于主小区(Primary cell)而信息2位于辅小区(Secondary cell)，则优先为信息1分配功率。
值得注意的是，以上各个实施方式仅对本发明实施例如何根据优先级分配功率进行了示例性说明，但本发明不限于此，还可以在以上各个实施方式的基础上进行适当的变型。例如，可以单独使用上述各个实施方式，也可以将以上各个实施方式中的一种或多种结合起来。
此外，本发明实施例也可以扩展到边链路数据信息与边链路反馈信息之间的优先级确定和功率分配。例如目的设备可能需要同时发送反馈信息和数据信息给不同的源设备，或者目的设备需要发送单播、广播和组播等多个数据信息，同样可以使用QoS参数决定数据信息的优先级，并根据数据信息和反馈信息的优先级进行后续功率分配。
在一个实施例中，第二设备还可以根据所述优先级为所述第二数据信息和/或所述反馈信息调整和/或选择发送资源。
图6是本发明实施例的反馈信息的另一示例图，如图6所示，例如针对第一数据信息(图6中使用PSCCH/PSSCH表示)的反馈信息表示为SFCI；发送SFCI的资源有可能重叠。
例如如图6所示，针对第一设备#m的候选发送资源集合如A所示，针对第一设备#n的候选发送资源集合如B所示，因此，位于重叠区域的资源601(或者资源602)有可能被确定为发送SFCI#m和SFCI#n的发送资源，从而导致资源冲突。
在一个实施方式中，在具有较低优先级的所述第二数据信息和/或所述反馈信息的发送资源与具有较高优先级的所述第二数据信息和/或所述反馈信息的发送资源重 叠的情况下，不发送具有较低优先级的所述第二数据信息和/或所述反馈信息。
例如，在SFCI#m和SFCI#n均被分配了资源601的情况下，如果SFCI#m的优先级大于SFCI#n的优先级，则第二设备使用资源601发送SFCI#m而不发送SFCI#n。
在另一个方式中，在具有较低优先级的所述第二数据信息和/或所述反馈信息的发送资源与具有较高优先级的所述第二数据信息和/或所述反馈信息的发送资源重叠的情况下，为具有较低优先级的所述第二数据信息和/或所述反馈信息重新选择发送资源。
例如，在SFCI#m和SFCI#n均被分配了资源601的情况下，如果SFCI#m的优先级大于SFCI#n的优先级，则第二设备使用资源601发送SFCI#m，并且重新选择资源发送SFCI#n，例如选择不重叠的资源603发送SFCI#n；或者也可以选择位于重叠区域的资源602发送SFCI#n。
在一个实施例中，上述候选资源集合可以由与该目的设备建立单播会话的源设备配置或者由基站配置。由于源设备和目的设备所处的干扰环境是独立的，源设备可以将自身所受接收干扰较小的资源集合作为候选资源集合，并配置和推荐给目的设备；目的设备可以根据自身干扰条件，在候选资源集合中选择自身所受发射干扰较小的资源用于反馈信息的发送，源设备在候选资源集合中盲检该反馈信息，从而可以提高反馈信息传输的可靠性。
以上各个实施例或实施方式仅对本发明实施例进行了示例性说明，但本发明不限于此，还可以在以上各个实施例或实施方式的基础上进行适当的变型。例如，可以单独使用上述各个实施例或实施方式，也可以将以上各个实施例或实施方式中的一种或多种结合起来。
由上述实施例可知，第二设备确定第二数据信息和/或反馈信息的优先级，根据所述优先级为所述第二数据信息和/或所述反馈信息分配功率。由此，可以实现同一设备支持多个单播会话或组播会话。
实施例2
例如，如实施例1所示，不同源设备所配置的候选资源集合可能重叠。如果目的设备在重叠的资源上发送反馈信息，则多个源设备都能够接收到该反馈信息。如果在重叠的资源上仅发送了优先级较高的反馈信息，则源设备需要能够分辨该反馈信息是 否是自己的反馈信息；或者如果在重叠的资源上发送了多个反馈信息，则源设备需要能够分辨哪一个反馈信息是自己的反馈信息。
再例如，考虑到一个源设备可能与多个目的设备建立单播会话，当多个目的设备在同一时隙发送反馈信息时，源设备也需要分辨哪一个反馈信息来自于哪一个目的设备。
再例如，考虑到源设备在候选资源集合内盲检反馈信息，其他建立了单播会话的源设备和目的设备也可能在该资源集合内发送反馈信息，因此源设备也需要能够分辨哪个反馈信息是发给自己的反馈信息。
再例如，即使不使用候选资源集合(目的设备不自主选择资源)，而是由源设备或基站通过信令通知目的设备使用某一资源来发送反馈信息，目的设备也可能被配置在相同的资源向多个源设备发送多个反馈信息，假设目的设备基于反馈信息优先级仅发送一个最高优先级的反馈信息，那么源设备也需要能够识别该反馈信息是否是发送给自己的反馈信息。
本发明实施例提供一种边链路信息的发送方法，从发送设备(也可称为第二设备、目的设备)侧进行说明。其中该发送设备可以是终端设备，但本发明不限于此，例如也可以是路侧设备或者网络设备。与实施例1相同的内容(例如反馈信息等)，可以参考实施例1。
图7是本发明实施例的边链路信息的发送方法的一示意图，如图7所示，所述方法包括：
步骤701，第二设备接收至少一个第一设备发送的第一数据信息和/或参考信号；
步骤702，所述第二设备使用标识对针对所述第一数据信息和/或所述参考信号的反馈信息和/或第二数据信息进行加扰和/或指示；以及
步骤703，所述第二设备向所述至少一个第一设备发送加扰和/或指示后的所述反馈信息和/或所述第二数据信息。
值得注意的是，以上附图7仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图7的记载。
在一个实施例中，所述标识可以包括如下至少之一：所述第一设备的标识、所述 第二设备的标识、会话标识、边链路标识、设备组标识；但本发明不限于此，还可以是其他的标识。
例如，由于源标识能够标识源设备，目的标识能够标识目的设备，会话标识可以标识单播会话，设备组标识可以表示组播会话；因此可以基于源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种来分辨反馈信息。
在一个实施例中，使用标识对所述反馈信息和/或所述第二数据信息进行加扰，可以包括：根据所述标识的至少一部分确定加扰序列生成函数的初始值；使用所述加扰序列生成函数生成加扰序列；以及使用所述加扰序列对所述反馈信息和/或所述第二数据信息的比特和/或循环冗余校验(CRC，Cyclic Redundancy Check)进行加扰。
例如，使用一个加扰序列对信息比特进行加扰，可以对信道编码前的信息比特加扰，也可以对编码后的信息比特加扰。某一加扰序列生成器以某一函数值作为初始值，生成上述加扰序列。上述函数可以以源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种作为自变量；例如可以使用TS 38.211标准5.2.1小节的序列作为加扰序列，并将初始值设为c init＝n D·2 15+n s，其中n D、n s分别表示目的标识和源标识。
再例如，使用一个加扰序列对信息的CRC进行加扰。某一加扰序列生成器以某一函数值作为初始值，生成上述加扰序列。上述函数可以以源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种作为自变量。
在一个实施例中，使用标识对所述反馈信息和/或所述第二数据信息进行指示，可以包括：根据所述标识确定所述反馈信息和/或所述第二数据信息所使用的序列、正交掩码(OCC，orthogonal cover code)、根序列、循环移位中的至少一项。
例如，当信息比特数为1比特或2比特时，可以通过发送序列集合中的某一序列对该信息进行指示。例如可以使用ZC序列的不同的根序列，对于某一根序列，可以使用不同的循环移位。可以基于源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种确定信息所使用的根序列和/或循环移位。又例如，可以使用不同的正交掩码；可以基于源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种确定信息所使用的正交掩码。
例如，假设可用的根序列数目为M，循环移位数目为N，可以对某一函数值取模M或取模N，将得到的结果作为序列、正交掩码、根序列、循环移位中的至少一项的 索引，确定序列、正交掩码、根序列、循环移位中的至少一项。上述函数可以以源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种作为自变量。
通过使用不同的序列、正交掩码、根序列、循环移位中的至少一项，可以对不同的反馈信息进行标识，从而减小或消除接收反馈信息时可能发生的混淆。某一单播会话所使用的序列、正交掩码、根序列、循环移位中的至少一项也可以在单播会话建立过程中通过信令指示，例如建立了多个单播会话的第一设备通过信令通知与其建立单播的第二设备所能使用的序列、正交掩码、根序列、循环移位中的至少一项，从而避免冲突和混淆。
在一个实施例中，使用标识对所述反馈和/或所述第二数据信息进行指示，还可以包括：将所述标识的至少一部分包含在所述反馈信息和/或所述第二数据信息的载荷中。
例如，将源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种作为反馈信息的载荷，在反馈信息中发送。
再例如，将源标识、目的标识、会话标识、边链路标识、设备组标识中的至少一种的一部分比特作为反馈信息的载荷，将剩余部分比特作为某一函数的自变量计算函数值，以该函数值作为某一加扰序列生成器的初始值而生成加扰序列，使用加扰序列对反馈信息比特和/或CRC进行加扰。
在一个实施例中，第二设备还可以在使用RM编码或小块长度编码的所述反馈信息中加入循环冗余校验，和/或，在小于或等于2比特的所述反馈信息中加入循环冗余校验。
例如，对所有反馈信息比特使用CRC和/或信道编码，即无论反馈信息使用何种信道编码，例如极化码(polar)、低密度奇偶校验码(LDPC，Low-Density Parity Check)、RM(Reed-Muller)、小块长度编码(channel coding of small block lengths)等，均使用CRC。考虑到第一设备会在候选资源集合内盲检反馈信息，通过引入CRC可以有效防止某一设备将发给其他设备的反馈信息当成自己的信息进行解释。
再例如，当反馈信息比特数为1比特或2比特时，可以对反馈信息比特执行重复、使用CRC和信道编码中的至少一种操作。
以上各个实施例或实施方式仅对本发明实施例进行了示例性说明，但本发明不限于此，还可以在以上各个实施例或实施方式的基础上进行适当的变型。例如，可以单 独使用上述各个实施例或实施方式，也可以将以上各个实施例或实施方式中的一种或多种结合起来。
由上述实施例可知，第二设备使用标识对反馈信息和/或第二数据信息进行加扰和/或指示。由此，可以实现同一设备支持多个单播会话或组播会话；此外，能够减少反馈信息所受到的干扰，以及避免多个设备的反馈信息发生混淆。
