如背景技术中所述，在目前侧边链路传输场景中，还没有讨论关于基于波束传输的相关内容。
本发明技术方案中，接收用户设备可以对侧边链路波束的测量参考信号进行测量，测量结果可以加入侧边链路信道状态信息报告。由于侧边链路的传输具有较高的实时性要求，因此为了保证侧边链路信道状态信息报告能够及时发送出去，接收用户设备可以基于是否在预设时长内获得传输机会确定是否传输侧边链路信道状态信息报告，本发明技术方案通过及时汇报侧边链路信道状态信息报告，保证基于波束的侧边链路的正常通信。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种侧边链路波束报告汇报方法的流程图。
本发明实施例的侧边链路波束报告汇报方法可以用于接收用户设备侧，也即可以由接收用户设备执行上述方法的各个步骤。
具体而言，侧边链路波束报告汇报方法可以包括以下步骤：
步骤101：测量针对侧边链路波束的测量参考信号，以得到测量结果；
步骤102：基于是否在预设时长内获得传输机会确定是否传输侧边链路信道状态信息报告，所述侧边链路信道状态信息报告包括所述测量结果。
相应地，发送终端设备可以接收侧边链路信道状态信息报告。进一步地，发送终端设备还可以将侧边链路信道状态信息报告进行上报，具体可以是上报至网络设备，例如上报至基站或上报至核心网设备。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
可以理解的是，在具体实施中，所述侧边链路波束报告汇报方法可以采用软件程序的方式实现，该软件程序运行于芯片或芯片模组内部集成的处理器中。该方法也可以采用软件结合硬件的方式实现，本申请不作限制。
本发明实施例提供了一种波束管理的方案。具体如波束的测量、侧边链路信道状态信息(Channel State Information,CSI)报告的汇报、侧边链路信道状态信息报告的传输等。
在步骤101的具体实施中，接收终端设备可以对侧边链路波束的测量参考信号进行测量，测量结果可以是层1的参考信号接收功率(Layer1 Reference Signal Receiving Power,L1-RSRP)，或者层1的信号与干扰加噪声比(Layer1 Signal to Interference plus Noise Ratio,L1-SINR)。具体地，测量参考信号可以是侧边链路同步信号块(Synchronzation Signal Block,SSB)，也可以是信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)。
上述测量结果可以加入侧边链路信道状态信息报告，侧边链路信道状态信息报告包括该测量结果，侧边链路信道状态信息报告还可以包括其他任意可实施的内容，本发明实施例对此不作限制。
由于侧边链路传输场景中对数据的实时性要求比较高，因此侧边链路信道状态信息报告需要及时发送给发送终端设备。故而在步骤102的具体实施中，接收终端设备可以基于是否在预设时长内获得传输机会来确定是否传输侧边链路信道状态信息报告。
在一种具体的实施方式中，如果接收终端设备在所述预设时长内获得传输机会，则传输所述侧边链路信道状态信息报告。
具体地，接收终端设备在获得传输机会时，可以利用该传输机会传输侧边链路数据。接收终端设备在预设时长内获得传输机会的话则利用该传输机会传输侧边链路信道状态信息报告，从而保证侧边链路信道状态信息报告的传输满足时延要求。
在另一种具体的实施方式中，如果接收终端设备未在所述预设时长内获得传输机会，则放弃传输所述侧边链路信道状态信息报告。
具体地，接收终端设备在超出预设时长才获得传输机会的话则放弃传输侧边链路信道状态信息报告，以避免浪费侧边链路资源。
在具体实施中，预设时长可以是由发送终端设备与接收终端设备预先约定好的，例如可以是在建立侧边链路时约定的，具体可以通过侧边链路高层信令配置。预设时长还可以是由网络侧设备预先配置的，例如通过网络侧设备所发送的高层信令配置。或者，预设时长还可以是预先定义的固定时长，例如可以由通信标准协议预先定义好。
本发明实施例通过及时汇报侧边链路信道状态信息报告，保证基于波束的侧边链路的正常通信。
在一个非限制性的实施例中，所述预设时长的起始时刻选自：触发所述侧边链路信道状态信息报告的信道的起始符号、触发所述侧边链路信道状态信息报告的信道的终止符号、所述测量参考信号的起始符号和所述测量参考信号的终止符号。
本实施例中，触发侧边链路信道状态信息报告的信道可以是物理边链路控制信道(Pysical Sidelink Control Channel,PSCCH)。预设时长的起始时刻可以是PSCCH的起始符号或终止符号。换言之，预设时长的起始时刻可以是承载PSCCH的资源的第一个符号(first symbol)或最后一个符号(end symbol)。
本实施例中，测量参考信号可以是SL-SSB或SL-CSI-RS，预设时长的起始时刻可以是SL-SSB的起始符号或终止符号，也就是说，预设时长的起始时刻可以是SL-SSB所占资源的第一个符号或最后一个符号。或者，预设时长的起始时刻可以是SL-CSI-RS的起始符号或终止符号，也就是说，预设时长的起始时刻可以是SL-CSI-RS所占资源的第一个符号或最后一个符号。
在一个非限制性的实施例中，所述预设时长采用以下形式表示： 时间窗口或者计时器(Timer)。
也就是说，接收终端设备在预设时长的时间窗口内获得传输机会，则传输所述侧边链路信道状态信息报告，否则放弃传输侧边链路信道状态信息报告。
或者，接收终端设备在计时器的计数为零时未获得传输机会，则放弃传输侧边链路信道状态信息报告，否则传输侧边链路信道状态信息报告。
在本发明一个非限制性的实施例中，所述侧边链路信道状态信息报告除了包括L1-RSRP以及L1-SINR之外，还可以包括所述测量参考信号的参考信号索引号。具体来说，所述测量参考信号的参考信号索引号可以是侧边链路SSB资源索引号或者侧边链路CSI-RS资源索引号。
在本发明的一个非限制性的实施例中，请参照图2，所述侧边链路波束报告汇报方法可以包括以下步骤：
步骤201：获取侧边链路信道状态信息报告，侧边链路信道状态信息报告包括针对侧边链路波束的测量参考信号的测量结果；
步骤202：通过PC5接口的MAC CE或PSFCH传输所述侧边链路信道状态信息报告。
本发明实施例的侧边链路波束报告汇报方法可以用于接收用户设备侧。
本发明实施例的PC5接口可以是指车辆的模组和车辆、路侧设备以及行人进行交互的接口。
在步骤201的具体实施中，接收用户设备获取侧边链路信道状态信息报告的过程可以是接收用户设备测量侧边链路波束的测量参考信号，并根据测量结果生成侧边链路信道状态信息报告。接收用户设备需要将侧边链路信道状态信息报告发送给发送用户设备。
具体地，接收用户设备和发送用户设备可以通过物理直接链路反馈信道(Physical Sidelink Feedback Channel,PSFCH)或PC5接口的MAC媒体接入控制(Media Access Control,MAC)控制元(Control Element，CE)传输侧边链路数据，那么在步骤202的具体实施中，接收用户设备可以通过PC5接口的MAC CE或PSFCH传输侧边链路信道状态信息报告。换言之，可以通过PC5接口的MAC CE或PSFCH传输以下一项或多项内容：L1-RSRP、L1-SINR、测量参考信号的参考信号索引号。
在一个非限制性的实施例中，步骤202的执行顺序可以位于图1所示步骤102之后，也即在接收用户设备确定传输侧边链路信道状态信息报告之后，再利用PC5接口的MAC CE或PSFCH传输该报告。
进一步而言，PC5接口的MAC CE还可以承载信道质量指示(Channel Quality Indicator,CQI)和秩指示(Rank indication,RI)。在这种情况下，承载侧边链路信道状态信息报告的MAC CE的逻辑信道优先级可以与承载信道质量指示和秩指示的MAC CE的逻辑信道优先级不同。具体地，可以是携带所述侧边链路信道状态信息报告的MAC CE的逻辑信道优先级高于携带信道质量指示和秩指示的MAC CE的逻辑信道优先级，或者，也可以是携带所述侧边链路信道状态信息报告的MAC CE的逻辑信道优先级低于携带信道质量指示和秩指示的MAC CE的逻辑信道优先级。
相对于现有技术中承载信道质量指示和秩指示的MAC CE而言，本申请中的MAC CE是一种新的MAC CE，其承载的内容与现有技术中MAC CE承载的内容不同。
进一步而言，目前的PSFCH可以承载混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)确认(ACK)，HARQ-ACK通常只占用PSFCH中的一个或两个比特。本发明实施例则对PSFCH承载的内容进行扩充，使其能够承载侧边链路信道状态信息报告，侧边链路信道状态信息报告需要占用更多的比特，例如11个比特等。相对 于现有技术中承载HARQ-ACK的PSFCH而言，本申请中的PSFCH是一种新的PSFCH。
在本发明的一个非限制性的实施例中，请参照图3，所述侧边链路波束报告汇报方法可以包括以下步骤：
步骤301：测量针对侧边链路波束的测量参考信号，以得到测量结果；
步骤302：根据所述测量结果与预设门限的关系确定是否触发上报侧边链路信道状态信息报告，所述侧边链路信道状态信息报告包括所述测量结果。
关于步骤301的具体实施方式可以参照图1所示步骤101的相关实施例，此处不再赘述。
在一个非限制性的实施例中，步骤302的执行顺序可以位于图1所示步骤102之后，也即在确定触发上报侧边链路信道状态信息报告之后，再判断是否传输该报告。
在步骤302的具体实施中，在测量结果低于预设门限时，意味着此时侧边链路的通信质量变差，接收用户设备需要触发上报侧边链路信道状态信息报告，以使得网络侧能够及时调整侧边链路传输资源，保证侧边链路通信质量。而在测量结果高于预设门限时，接收用户设备不触发上报侧边链路信道状态信息报告。
在一个具体实施例中，预设门限可以是由网络设备(例如基站)通过高层信令预先配置的，也可以是由发送用户设备与接收用户设备通过PC5接口高层信令预先配置的，或还可以是由通信标准协议约定的固定的数值，本发明实施例对此不作限制。
在本发明的一个非限制性的实施例中，请参照图4，所述侧边链路波束报告汇报方法可以包括以下步骤：
步骤401：接收侧边链路信道状态信息报告，所述侧边链路信道 状态信息报告包括测量结果，所述测量结果是接收终端设备测量针对侧边链路的测量参考信号得到的；
步骤402：根据侧边链路信道状态信息报告的第一优先级以及侧边链路数据的第二优先级确定传输内容，传输内容包括侧边链路信道状态信息报告和/或侧边链路数据。
本发明实施例的侧边链路波束报告汇报方法可以用于发送终端设备。
具体实施中，发送终端设备可以将来自接收终端设备的侧边链路信道状态信息报告转发至网络设备。
当发送终端设备可以把侧边链路的波束测量结果汇报给网络设备时，如果发送终端设备还进行侧边链路的传输(例如在不同的载波上进行上行传输和侧边链路传输)。此时如果发送终端设备没有能力进行同时进行上行传输和侧边链路传输，或者发送终端设备有能力进行同时进行上行传输和侧边链路传输，但是其处于功率限制(power limited)场景下，发送终端设备需要选择一种类型的传输内容进行传输。
在步骤402的具体实施中，如果传输所述侧边链路信道状态信息报告与传输侧边链路数据发生冲突，则发送终端设备可以分别确定侧边链路信道状态信息报告的第一优先级以及侧边链路数据的第二优先级，并根据第一优先级和第二优先级的大小关系确定传输侧边链路信道状态信息报告或侧边链路数据。
例如，第一优先级大于第二优先级的情况下，发送终端设备发送侧边链路信道状态信息报告；第一优先级小于第二优先级的情况下，发送终端设备发送侧边链路数据。
在一个非限制性的实施例中，利用所述侧边链路信道状态信息报告的属性信息确定所述侧边链路信道状态信息报告的第一优先级；按照所述第一优先级与第一预设阈值的大小关系确定所述侧边链路信 道状态信息报告为高优先级报告或低优先级报告；确定所述侧边链路数据的第二优先级，并根据所述第二优先级与第二预设阈值的大小关系确定所述侧边链路数据为高优先级数据或低优先级数据；按照所述高优先级报告、所述低优先级报告、所述高优先级数据与所述低优先级数据之间的预设传输顺序确定传输所述侧边链路信道状态信息报告或所述侧边链路数据。
本实施例中，第一预设阈值和第二预设阈值可以是网络设备通过高层信令配置的。
通过第一优先级与第一预设阈值的关系可以将侧边链路信道状态信息报告划分为高优先级报告、低优先级报告；通过第二优先级与第二预设阈值的关系可以将侧边链路数据划分为高优先级数据与低优先级数据。优先级从大到小的顺序为：高优先级报告、低优先级报告、高优先级数据与低优先级数据。优先级高的数据的传输顺序优先于优先级低的数据的传输顺序。
具体地，可以根据侧边链路信道状态信息报告的内容、周期特性、报告表示等计算第一优先级。例如采用以下公式计算第一优先级：Pri(y,k,c,s)＝2×Ncells×Ms×y+Ncells×Ms×k+Ms×c+s，其中，Ncells表示最大服务小区个数(maxNrofServingCells)；Ms表示最大CSI汇报配置个数(maxNrofCSI-ReportConfigurations)；y表示周期特性，如PUSCH发送非周期CSI汇报(aperiodic CSI on PUSCH)时，y为0，PUSCH发送半持续CSI汇报(Semi-Persistant CSI on PUSCH)时，y为1，PUCCH发送半持续CSI汇报(Semi-Persistant CSI on PUCCH)时，y为2，PUCCH发送周期性CSI汇报(Periodic CSI on PUCCH)时，y为3。K表示CSI汇报是否包含L1-RSRP，具体地，CSI汇报包含L1-RSRP时，k为0，CSI汇报不包含L1-RSRP时，k为1。C表示服务小区序号(serving cell index)。s表示汇报配置序号(reportConfigID)。
按照上述公式计算出来的第一优先级的数值越小代表优先级越 高。
在本发明另一个非限制性的实施例中，步骤402可以包括以下步骤：如果传输所述侧边链路信道状态信息报告与传输侧边链路数据发生冲突，则按照所述侧边链路信道状态信息报告的优先级与所述侧边链路数据的优先级的预设关系，确定传输所述侧边链路信道状态信息报告或所述侧边链路数据。
本发明实施例中，侧边链路信道状态信息报告的优先级与所述侧边链路数据的优先级的关系可以是预先配置好的。例如可以是侧边链路信道状态信息报告的优先级高于侧边链路数据的优先级，或者也可以是侧边链路信道状态信息报告的优先级低于侧边链路数据的优先级。
在本发明的一个非限制性的实施例中，请参照图5，所述侧边链路波束报告汇报方法可以包括以下步骤：
步骤501：在侧边链路控制信息中通过信道状态信息请求域触发所述侧边链路信道状态信息报告的上报。
步骤502：接收侧边链路信道状态信息报告，所述侧边链路信道状态信息报告包括测量结果，所述测量结果是接收终端设备测量针对侧边链路波束的测量参考信号得到的。
本实施例中，发送终端设备可以在直接链路控制信息(Sidelink Control Information,SCI)中的信道状态信息请求域触发报告的汇报。具体地，发送终端设备可以在第二阶段SCI(2nd SCI)中通过信道状态信息请求域来触发报告的汇报。
通过信道状态信息请求域携带的内容，接收终端设备能够获知测量哪些测量参考信号(例如哪些SSB或哪些参考信号索引)以及是否汇报侧边链路信道状态信息报告。那么在发送终端设备触发报告的情况下，接收终端设备汇报侧边链路信道状态信息报告，发送终端设备接收该报告。
进一步而言，在步骤501之前可以包括以下步骤：发送终端设备可以接收来自核心网设备的触发指示信息，所述触发指示信息用于指示触发所述侧边链路信道状态信息报告的上报。
也就是说，核心网设备通过下行控制信息(Downlink Control Information,DCI)告知发送终端设备要触发一个侧边链路信道状态信息报告汇报，然后发送终端设备在SCI(2nd SCI)中通过信道状态信息请求域来触发报告的汇报。
