具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。附图中仅示出了与本申请相关的部分而非全部结构。
实施例一
图1a为本申请实施例一中的一种通信数据调度处理方法的流程图，本实施例可适用于多级节点网络中进行通信数据调度处理的情况，该方法可以由本申请实施例提供的通信数据调度处理装置来执行，该装置可采用软件和/或硬件的 方式实现，并可集成在计算机设备中。
本申请实施例中，用于传输数据的物理信道包括以下信道。物理直连共享信道(Physical Sidelink Shared Channel，PSSCH)：是用于承载数据的信道；编码、速率匹配和交织等物理层处理机制与终端对终端(Device-to-Device，D2D)相同。物理控制信道(Physical Sidelink Control Channel，PSCCH)：是用于承载控制信息的信道，控制信息包括如调度分配信令(Scheduling Assignment，SA)等；编码、速率匹配和交织等物理层处理机制与D2D相同。物理广播信道(Physical Sidelink Broadcast Channel，PSBCH)：是用于同步控制及调整的信道。其中，PSCCH用于指示PSSCH传输的时频域资源位置、调制编码方式和PSSCH所针对的接收目标标识信息(IDentity，ID)等信息，PSSCH用于承载数据。
传输的信号类型包括解调参考信号(Demodulation Reference Signals，DMRS)和同步信号(Synchronization Signals，SS)。其中，DMRS与PSSCH，PSCCH以及PSBCH一起发送，用于上述信道的解调。SS包括主同步信号(Primary Sidelink Synchronization Signals，PSSS)与辅同步信号(Secondary Sidelink Synchronization Signals，SSSS)。PSSS为SideLink主同步信号，SSSS为SideLink辅同步信号。通过PSSS和SSSS可以获取小区ID，小区ID分成两个集合：id_net以及id_oon。PSSS的产生与D2D相同，SSSS采用LTE子帧5的SS序列。
在一个例子中，本申请实施例采用长期演进车联网(Long Term Evolution Vehicle，LTE-V)技术。LTE-V是面向智能交通和车联网应用，并基于4G LTE系统的演进技术。LTE-V可以借助蜂窝网络，支持大带宽和大覆盖通信需求；LTE-V也可以独立于蜂窝网络，实现车辆之间以及车辆与周边环境节点之间的低时延、和高可靠的直接通信，满足行车安全需求。LTE-V在PC5接口上只能使用半双工操作(Half duplex Communication，HD)。LTE-V的DMRS发送与LTE上行共享物理信道(Physical Uplink Share Channel，PUSCH)的DMRS发送相同，频域上与发送信道带宽一致，最多占满整个带宽，时域上加密设计，以支持高速移动。
在物理信道中进行数据传输时，时域结构如图1b所示。在采用的子帧结构中，PSCCH或PSSCH子帧中包含4个DMRS符号，其他为数据符号。数据符号中第1个符号(编号0)用于子帧的自动增益控制(Automatic Gain Control，AGC)调整，而最后一个符号不发送，作为保护间隔。
频域结构如图1c和图1d所示。图1c为采用邻带传输方式的资源池配置的示意图，图1d为采用非邻带传输方式的资源池配置的示意图。图1c和图1d中该资源池的时域资源为一个符号占用的时间片。
在邻带传输方式中：
PSCCHandPSSCH的资源块相邻(Adjacency of PSCCH and PSSCH Resource Blocks)：用于指示SA和数据(data)是否采用邻带的传输方式。
如果采用邻带的传输方式，那么在邻带的资源池配置中，SA的资源总是位于一个子信道的物理资源块(Physical Resource Block，PRB)中最低的2个PRB，且每个子信道中只有一个SA信道。
如图1c所示，资源池配置中包含的参数如下：
子信道的大小(Subchannel size)：可配置的参数为{5,6,10,15,20,25,50,75,100}；子信道的个数(Number of subchannels)：可配置的参数为{1,3,5,8,10,15,20}；子信道起始的资源块(Resource Block，RB)索引(Starting RB of subchannels)：从{0,…,99}中取整数。
如果采用非邻带的传输方式，SA的资源与子信道有着一一对应的关系，相应的SA信道的个数与子信道的个数是相同的。如图1d所示，资源池配置中包含的参数如下：
Subchannel size：可配置的参数为{4,5,6,8,9,10,12,15,16,18,20,30,48,72,96}；Number of subchannels：可配置的参数为{1,3,5,8,10,15,20}；Starting RB of subchannels：从{0,…,99}中取整数；PSCCH资源的起始RB索引(Starting RB of PSCCH pool)：从{0,…,99}中取整数，这个参数如果在邻带传输方式下可以不需要。
如图1a所示，本实施例的方法包括以下步骤。
S110，在物理控制信道中，获取至少一个目标发送设备的目标发送设备信息。
物理控制信道用于传输控制信息，示例性的，物理控制信道为基于LTE-V技术的通信网络的PSCCH。控制信息用于接收端确定对应的PSSCH传输的时频域资源位置、调制编码方式和PSSCH所针对的接收目标标识信息(IDentity，ID)等信息。
本申请实施例实现通信数据调度处理方法的计算机设备为LTE-V中接收设备。目标发送设备为LTE-V中发送设备。其中，接收设备通常为车载终端。目标发送设备可以包括下述至少一项：车载终端、路侧设施终端、用户终端和网络(例如局域网)等。其中，路侧设施终端可以包括交通灯终端、路牌终端或路侧建筑终端等。
可选的，所述目标发送设备包括车联网中节点，所述节点包括交通灯设备、 车辆设备或用户设备。
目标发送设备和接收设备均为车联网中节点。在车联网中一个接收设备可以同时接收多个目标发送设备发送的信号。节点可以是交通灯设备、车辆设备或用户设备。交通灯设备可以提供交通灯位置信息和信号灯信息，便于接收设备对交通灯设备进行避障、根据交通灯信号进行行驶和刹车、或者根据多个交通灯信号进行路线规划等。车辆设备可以提供车辆自身位置信息和自身行驶状态信息等，便于接收设备对车辆设备进行避障、行驶状态调整和路线规划等。用户设备可以提供用户自身位置和自身移动状态(包括静止状态和运动状态)，便于接收设备对路人进行避障。通常，接收设备为车辆设备。
通过配置目标发送设备为车联网节点，并配置车联网节点包括多种类型的设备，可以增加目标发送设备的数据的多样性，增加车联网中接收设备的应用场景。
发送设备信息用于确定处理次序。发送设备信息可以是指发送设备关联的数据，可以包括下述至少一项：发送设备的标识信息(或车的名称、用户名称或路侧设备名称等)、发送设备的类型、发送设备的属性信息(如车的品牌、用户性别或路侧设备的功能)和发送设备的配置信息(如发送设备的预先配置的优先级)等。其中，发送设备信息可以从控制信息中提取得到。
可选的，所述在物理控制信道中，获取至少一个目标发送设备的目标发送设备信息，包括：在子帧的有效符号数据中对物理控制信道对应的数据进行信道估计、解调和译码；如果译码结果正确，则从正确译码结果中提取至少一个目标发送设备的目标发送设备信息。
接收设备是以子帧为单位进行数据处理，即接收设备处理完一个子帧，继续处理下一个子帧。一个子帧通常包括14个符号，例如图1b所示，其中首尾两个符号不用于传输数据。有效符号数据为中间12个符号。有效符号数据为用于承载有效信息的符号，例如，承载控制信息和承载传输数据。物理控制信道对应的数据可以是指物理控制信道承载的控制信息，物理控制信道对应的数据包括多个子信道承载的控制信息，或者包括多个目标发送设备对应的控制信息。
译码结果正确表明，可以得到正确的控制信息，由此，可以根据正确的控制信息，对对应的传输数据进行信道估计、解调和译码。正确的译码结果中包括发送设备信息，可以直接从译码结果中提取发送设备信息。如果译码结果错误，则记录译码错误的目标发送设备，以便后续根据重传的数据进行合并以形成正确的译码结果。
在物理共享信道中，获取所述至少一个目标发送设备对应的传输数据，包 括：在子帧的有效符号数据中对物理控制信道对应的数据进行提取，获取所述至少一个目标发送设备对应的传输数据。
通过以子帧为单位对数据进行处理，可以快速获取有效符号数据，并进行发送设备信息提取，从而获取至少一个目标发送设备的传输数据进行调度处理，减少数据堆积，可以提高通信数据解析效率。
S120，根据每个目标发送设备信息，确定每个目标发送设备对应的数据处理次序。
数据处理次序用于对不同目标发送设备的数据先后进行调度处理。数据处理次序可以是指对不同目标发送设备对应的数据进行处理的次序。其中，目标发送设备对应的数据为物理共享信道中与目标发送设备对应的子信道承载的数据。实际上，一个目标发送设备可以与物理共享信道中多个子信道对应，即对应的多个子信道承载的数据均为目标发送设备发送的数据。示例性的，可以根据发送设备信息，对至少一个目标发送设备进行划分，并确定每个分组的优先级，同时组内还可以继续根据发送设备信息进行细分，并确定每个分类的优先级，其中，优先级高的数据处理次序在前，优先级低的数据处理次序在后。
可选的，所述根据每个目标发送设备信息，确定每个目标发送设备对应的数据处理次序，包括：根据每个目标发送设备信息包括的重传标识信息以及至少一个目标发送设备对应的初传译码结果类型，将所述至少一个目标发送设备划分为重传待合并发送设备和非重传待合并发送设备，并确定每个目标发送设备对应的数据处理次序，其中，所述重传待合并发送设备的发送设备数据处理次序前于所述非重传待合并发送设备的发送设备数据处理次序；在相同类型的目标发送设备中，根据每个目标发送设备信息包括的调度指示优先级，确定多个相同类型的目标发送设备对应的数据处理次序，优先级高的发送设备数据处理次序前于优先级低的发送设备数据处理次序；在相同优先级的目标发送设备中，根据每个目标发送设备信息包括的信噪比，确定多个相同优先级的目标发送设备对应的数据处理次序，信噪比高的发送设备数据处理次序前于信噪比低的发送设备数据处理次序。
重传标识信息用于判断发送设备对应的子信道中数据包(包括控制信息和传输数据)是否为重传数据包。通常，数据包的类型可以包括初传数据包和重传数据包。为了避免初传数据包存在丢包的情况，发送设备可以重新发送该数据包，重新发送的数据包即为重传数据包，重传数据包用于接收设备获取准确未丢数据的数据包，以提高数据传输准确率。重传标识信息可以包括初传且无重传标识、初传且有重传标识和重传标识。其中，初传且无重传标识用于标识当前数据包为初传数据包，且对应的发送设备不会发送对应的重传数据包。初 传且有重传标识用于标识当前数据包为初传数据包，且对应的发送设备会发送对应的重传数据包，例如，可以在后一子帧中发送或后第n个子帧中发送重传数据包。重传标识用于标识当前数据包为重传数据包。初传译码结果类型用于判断发送设备发送的初传数据包的译码结果是否正确。通常初传译码结果类型为正确译码结果对应的重传数据包可以无需继续处理，可以丢弃。
优先判断目标发送设备的类型，并根据目标发送设备的类型确定不同类型的数据处理次序。根据重传标识信息和初传译码结果类型，对至少一个目标发送设备进行分类，其中，目标发送设备的类型可以包括：重传待合并发送设备类型和非重传待合并发送设备类型。将标记有重传标识，且初传译码结果类型为错误译码结果对应的重传数据包对应的目标发送设备的类型，确定为重传待合并发送设备类型。其余类型均为非重传待合并发送设备类型。例如，标记有初传且无重传标识和初传且有重传标识的初传数据包对应的目标发送设备，以及标记有重传标识且初传译码结果类型为正确译码结果对应的重传数据包对应的目标发送设备，目标发送设备对应的类型为非重传待合并发送设备类型。这样设置的好处在于，可以将历史没有正确译码的数据进行处理，提高通信网络对通信数据的容错性，同时可以减少译码错误的数据包的处理。
其次，在同一类型中，继续根据调度指示优先级对目标发送设备继续划分，并根据划分结果确定数据处理次序。在同一类型的多个目标发送设备中，根据调度指示优先级，对同一类型的目标发送设备进行划分，并根据划分结果确定数据处理次序，优先级高的数据处理次序越靠前，优先级低的数据处理次序越靠后。调度指示优先级可以是指在SA信令中包括的优先级，通常该优先级为根据任一指标(可以根据需要进行配置)预先配置的优先级，例如，根据目标发送设备的类型预先配置的优先级。示例性的，用户设备的优先级为3，交通灯设备的优先级为2，车辆设备的优先级为1。这样设置的好处在于，可以将关键信号，或者重要程度较高的信号优先进行处理，可以对紧急事件进行响应，提高接收设备的可靠性，以及提高通信网络的传输可靠性。
再次，在同一优先级的多个目标发送设备中，根据信噪比(Signal Noise Ratio，SNR)，对同一优先级的目标发送设备进行划分，并根据划分结果确定数据处理次序，信噪比高的数据处理次序越靠前，信噪比低的数据处理次序越靠后。信噪比可以是指接收设备检测与目标发送设备之间信道的通信质量，其中，信噪比可以根据信道估计结果确定。这样设置的好处在于，可以优先处理信号质量好的数据包，后处理信号质量差的数据包，可以减少信号质量差的数据包出现错误带来的影响，从而提高通信网络的可靠性。
实际上，在接收设备处理能力受限的情况下，优先调度处理可以重传合并 的目标发送设备，如果还有能力则调度处理高优先级的目标发送设备，相同优先级的情况下，优先调度PSCCH信道的信噪比高的目标发送设备。
通过配置目标发送设备的类型、调度指示优先级和信噪比，并根据前述参数，依次确定至少一个目标发送设备的数据处理次序，可以实现在处理能力受限的情况下，避免了不必要的处理开销，使有限的处理能力能够用在关键的目标发送设备发送的传输数据的处理操作上，提高了系统的可靠性。
S130，在物理共享信道中，获取所述至少一个目标发送设备对应的传输数据。
物理共享信道用于传输数据，示例性的，物理共享信道为基于LTE-V技术的通信网络的PSSCH。传输数据可以是指物理共享信道中承载的数据，传输数据用于接收设备进行调度处理以获取有效数据并通过接收设备对传输数据进行处理操作。例如，处理操作可以包括对目标发送设备进行避障操作、接收设备的行驶方向和行驶速度的调整操作、接收设备的行驶路线的规划操作和目标发送设备的预警提示的生成操作等。
S140，按照所述至少一个目标发送设备对应的数据处理次序分别对所述至少一个目标发送设备对应的传输数据进行调度处理。
数据处理次序规定了接收设备对至少一个目标发送设备发送的数据进行处理的处理次序。调度处理可以包括接收设备对传输数据进行信道估计、均衡解调和信道译码等。信道估计可以是指利用导频符号对信道传输特性进行估计。均衡解调，包括均衡和解调，其中，均衡可以是指利用信道估计结果对传输信道的非理想引起的信号失真进行补偿，同时实现多天线接收信号的最大比合并。解调可以是指对来自均衡处理后的信号进行离散傅立叶反变换(Inverse Discrete Fourier Transform，IDFT)，将频域信号变换到时域。根据调制方式的不同，时域信号再经相应的星座解映射变换为串行的解调数据。信道译码可以是指对数据进行解扰、解信道交织和译码等。
本申请实施例通过对物理控制信道中数据进行提取，获取至少一个目标发送设备的目标发送设备信息，并根据发送设备信息，确定每个目标发送设备的数据处理次序，并按照数据处理次序对至少一个目标发送设备对应的信道中承载的传输数据进行处理，可以解决对每个发送端在信道中的传输数据进行解调和译码，资源浪费的问题，可以按照数据处理次序，对至少一个发送端的传输数据进行顺序调度处理，合理配置信道数据的调度资源，提高调度资源利用率，提高通信网络的可靠性。
实施例二
图2a为本申请实施例二中的一种通信数据调度处理方法的流程图，本实施例以上述实施例为基础进行说明。本实施例的方法包括以下步骤。
S210，在物理控制信道中，获取至少一个发送设备的发送设备信息。
对物理控制信道中的数据进行信道估计、均衡解调和信道译码等，获取该子帧关联的发送设备的发送设备信息。示例性的，如图1c和图1d所示，对调度分配信令(SA信令)所在的信道进行信道估计、均衡解调和信道译码等，获取至少一个发送设备的发送设备信息。
S220，根据所述发送设备信息在至少一个发送设备中确定坏点发送设备，并剔除所述坏点发送设备。
将坏点发送设备从目标发送设备中剔除，对该坏点发送设备关联的传输数据不进行解析。在子帧关联的发送设备中，坏点发送设备可以是指不进行调度处理的发送设备。剔除用于对发送设备进行筛选，以筛除坏点发送设备。
对于PSSCH信道，由于发送设备对应的每个子帧的最后一个符号用做收发切换的间隔(GAP)，接收端首个符号用做AGC捕获，打孔掉两个符号后，在一些调制与编码策略(Modulation and Coding Scheme，MCS)和RB个数的配置组合时，即使在理想信道情况下对应的传输块大小(Transport Block Size，TBS)码块，也无法正确译码。可以根据发送设备信息查找这样的设备，并不进行后续的传输数据的调度处理，避免执行译码错误之前的信道估计和均衡解调等操作，可以避免资源浪费。
可选的，所述根据至少一个发送设备的发送设备信息在至少一个发送设备中确定坏点发送设备，包括：根据每个发送设备信息包括的物理层协议的版本信息、传输次数和传输格式，确定目标发送设备信息匹配的坏点发送设备映射关系；根据发送设备信息包括的调制与编码策略标识，以及所述发送设备信息匹配的坏点发送设备映射关系，在至少一个发送设备中确定坏点发送设备。
可以预先配置调制与编码策略标识与坏点发送设备之间的映射关系表，并配置物理层协议的版本信息、传输次数和传输格式与映射关系表之间的映射关系。从而，可以通过物理层协议的版本信息、传输次数和传输格式查询映射关系表，并在查询到的映射关系表中查询与调制编码策略标识匹配的坏点发送设备。其中，初传且无重传标识的传输次数为单次传输，初传且有重传标识，以及重传标识的传输次数为两次传输，通常，传输次数包括单次传输或两次传输。物理层协议的版本信息、传输次数、传输格式和调制与编码策略标识均为SA信令中包括的数据。前述映射关系为统计实验确定。
通过配置调制与编码策略标识与坏点发送设备之间的映射关系，以及物理层协议的版本信息、传输次数和传输格式与映射关系之间的关系，可以根据预先配置的关系，确定坏点发送设备，可以提高坏点发送设备的确定效率和准确率。
可选的，所述坏点发送设备映射关系，包括：坏点映射表和坏点标识范围；所述根据每个发送设备信息包括的调制与编码策略标识，以及所述发送设备信息匹配的坏点发送设备映射关系，在至少一个发送设备中确定坏点发送设备，包括：在所述发送设备信息匹配的坏点映射表中，根据每个发送设备信息包括的调制与编码策略标识，查询发送设备信息对应的坏点资源块标识信息；如果确定所述发送设备的发送设备信息包括的资源块标识信息与所述发送设备的发送设备信息对应的坏点资源块标识信息匹配，则确定所述发送设备为坏点发送设备；在所述发送设备信息匹配的坏点标识范围中，获取所述发送设备信息对应的调制与编码策略标识；如果确定所述发送设备的发送设备信息包括的调制与编码策略标识与所述对应的坏点标识范围匹配，则确定所述发送设备为坏点发送设备。
坏点映射表存储有调制与编码策略标识与坏点资源块标识信息之间的映射关系，用于根据调制与编码策略标识，查询匹配的坏点资源块标识信息。坏点资源块标识信息为坏点发送设备对应的资源块标识信息。通常，在一些调制与编码策略标识对应的资源块中，即使在理想信道的情况下，也无法正确译码。可以将这些无法正确译码的调制与编码策略标识对应的资源块配置为坏点映射表。
若发送设备的发送设备信息包括的资源块标识信息与发送设备对应的坏点资源块标识信息匹配，即发送设备在子帧或者有效符号数据中承载传输数据的至少一个资源块，属于发送设备对应的坏点资源块的范围中，则确定所述发送设备为坏点发送设备。如图2b所示，发送设备0在子帧或者有效符号数据中承载传输数据和控制信息的至少一个资源块，可以是指承载调度分配信令0和数据0的资源块，包括10个资源块，资源块的标识可以为1-10，如果坏点资源块的范围包括9、12和15，则该发送设备的发送设备信息包括的资源块标识信息与发送设备对应的坏点资源块标识信息匹配，该发送设备为坏点发送设备。
坏点标识范围可以是指坏点发送设备对应的调制与编码策略标识的集合。发送设备的发送设备信息包括的调制与编码策略标识与对应的坏点标识范围匹配，可以是指调制与编码策略标识属于坏点标识范围。
可以根据物理层协议的版本信息、传输次数和传输格式，确定匹配的是坏点映射表还是坏点标识范围，并相应选择不同的参数进行查询，确定发送设备。
示例性的，物理层协议的版本信息为R14版本或者R15版本，传输格式为0；PSCCH信道译码结果里指示的传输次数是单次传输。
此时查询到的映射关系包括第一坏点映射表和第一坏点标识范围，其中，第一坏点映射表为0-20范围的调制与编码策略标识与坏点资源块标识信息之间的映射关系。第一坏点标识范围为21～28范围。即如果发送设备的调制与编码策略标识属于0-20范围，则根据发送设备的调制与编码策略标识在第一坏点映射表中查询坏点资源块标识信息，并在发送设备对应的资源块标识信息与查询到的坏点资源块标识信息中的任意一个相同时，则该发送设备为坏点发送设备；如果发送设备的调制与编码策略标识属于21～28范围，则该发送设备为坏点发送设备。
又如，物理层协议的版本信息为R14版本或者R15版本，传输格式为0；PSCCH信道译码结果里指示的传输次数是两次传输。
如果当前数据包为初传数据包和重传数据包，此时查询到的映射关系包括第二坏点映射表。其中，第二坏点映射表为0-28范围的调制与编码策略标识与坏点资源块标识信息之间的映射关系。如果发送设备的调制与编码策略标识属于0-28范围，则根据发送设备的调制与编码策略标识在第二坏点映射表中查询坏点资源块标识信息，并在发送设备对应的资源块标识信息与查询到的坏点资源块标识信息中的任意一个相同时，确定该发送设备为坏点发送设备。
如果当前数据包仅包括重传数据包，此时查询到的映射关系包括第三坏点映射表和第二坏点标识范围，其中，第三坏点映射表为0-20范围的调制与编码策略标识与坏点资源块标识信息之间的映射关系。第二坏点标识范围为21～28范围。即如果发送设备的调制与编码策略标识属于0-20范围，则根据发送设备的调制与编码策略标识在第三坏点映射表中查询坏点资源块标识信息，并在发送设备对应的资源块标识信息与查询到的坏点资源块标识信息中的任意一个相同时，该发送设备为坏点发送设备；如果发送设备的调制与编码策略标识属于21～28范围，则该发送设备为坏点发送设备。
又如，物理层协议的版本信息为R15版本，传输格式为1；PSCCH信道译码结果里指示的传输次数是单次传输。
如果此时查询到的映射关系包括第四坏点映射表。根据发送设备的调制与编码策略标识在第四坏点映射表中查询坏点资源块标识信息，并在发送设备对应的资源块标识信息与查询到的坏点资源块标识信息中的任意一个相同时，该发送设备为坏点发送设备。
在一个例子中，第一坏点映射表如表1所示，其中，I MCS为调制与编码策略 标识，I TBS为传输块大小(比特为单位)，N PRB为坏点资源块标识信息。

通过坏点发送设备映射关系，包括坏点映射表和坏点标识范围，并根据不同映射情况，适配性选择从不同的映射关系中确定坏点发送设备，可以灵活配置坏点发送设备的确定方式，并准确确定坏点发送设备。
S230，将剩余的发送设备确定为目标发送设备，并获取至少一个目标发送 设备的目标发送设备信息。
