Description

资源分配的方法及装置
本申请要求于2019年08月13日提交国家知识产权局、申请号为201910745871.9、发明名称为“资源分配的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及资源分配的方法及装置。
背景技术
目前，多个终端设备，如手机和车载终端，可以组成一个终端设备组，并在同一个部分带宽(bandwidth part，BWP，又称为带宽部分)上建立侧行链路(side link，SL)，以便实现组内直接通信。车联任意事物(vehicle to everything，V2X)系统是将车辆与一切事物相连接的新一代信息通信技术，其中V代表车辆，X代表与车交互信息的对象，当前X主要包含车、人、交通路侧基础设施和网络。在V2X或设备到设备(device to device，D2D)通信传输时，需要确定传输资源。因为V2X系统存在周期性的业务，也就是说V2X通信需要在时间上一直都配置有可供SL使用的传输资源。当然也有非周期性的业务,可以动态地配置可供SL使用的传输资源。因此需要提供一种机制，以便能够向做V2X或D2D通信的设备高效地指示传输资源。终端之间通过SL进行通信传输时，有如下两种指示SL传输资源的模式，一种是基站调度，即终端每次进行SL通信之前，基站均会向终端指示传输资源，另一种是基于终端设备感知，基站提前为终端配置资源池，后续，当终端进行SL通信时，从资源池中自行选择所需的传输资源。
随着第五代(5th generation，5G)移动通信系统的研究，下一代无线通信环境可能更复杂，比如，具有更多数目的终端设备，需要更高的通信质量。因此，现在亟需一种适应5G通信系统或类似通信系统的资源分配方法，以便指示用于SL的资源，从而满足终端的通信需求。
发明内容
本申请的实施例提供一种资源分配的方法及装置，可以更加灵活的在NR-V2X中指示用于SL的资源。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种资源分配的方法，该方法可以由能够实现接入网设备功能的装置执行，该装置可以为接入网设备，或者，可以为与接入网设备匹配使用的装置，该装置可以支持接入网设备实现接入网设备的功能，比如，该装置可以为接入网设备中的芯片系统，该方法可以包括：接入网设备确定资源指示信息，该资源指示信息用于指示侧行链路SL的传输资源，SL的传输资源包括第一资源和/或第二资源，第一资源包括一个或多个第一时隙，第二资源包括一个或多个第二时隙；其中，第一时隙中用于SL传输的符号数不同于第二时隙中用于SL传输的符号数；接入网设备向终端设备发送资源指示信息。
如此，为终端配置的用于SL传输的资源可以是整个时隙，也可以是时隙中的某一个或一些符号，使得资源配置粒度更加精细化。相对于现有技术中，只能够实现时隙级别的 用于SL传输资源的配置，本申请的技术方案，可以更加灵活的配置终端设备中用于SL传输的资源，提高终端设备传输SL资源的效率，应用于更加复杂的通信环境。
结合第一方面，在第一方面的第一种可能的实现方式中，每一第一时隙中的全部符号用于SL传输，每一第二时隙中的部分符号用于SL传输。
结合第一方面，在第一方面的第二种可能的实现方式中，资源指示信息包括第一SL资源位图，该第一SL资源位图中的比特位数为可用于SL传输的时隙数的P倍，P为正整数。

如此，通过基站指示资源指示信息中的一部分，资源指示信息中的另一部分可以与配置在终端设备中。比如，基站向终端发送包括001010这6个比特的资源指示信息，用于指示第1、2、4、6个时隙为部分符号用于SL传输的时隙。第3、5个时隙中的全部符号用于SL传输。其中，具体部分符号指的是哪些符号，可以预配置在终端中。比如，终端预配置时隙中的第一至第四个符号用于SL传输。则终端仅需通过基站接收6比特信息，就可以获知具体使用哪些符号进行SL传输。终端无需从基站获取关于部分符号的起始位置和符号个数的具体指示，节约了基站向终端发送信令的开销，能够提升网络的资源利用率。
结合第一方面，在第一方面的第四种可能的实现方式中，资源指示信息还包括第二SL资源位图，该第二SL资源位图中的比特位数为可用于SL传输的时隙数的Q倍，Q为正整数；第一SL资源位图中的比特取值用于指示对应的时隙是否全部符号用于SL传输；若Q为1，第二SL资源位图中的比特取值用于指示对应的时隙是否部分符号用于SL传输；若Q为大于1的整数，第二SL资源位图中相邻Q个比特取值用于指示对应的时隙中用于SL传输的符号的起始位置以及符号个数，其中，相邻Q个比特包括第二SL资源位图中的第y至第y+(Q-1)个比特，y+(Q-1)能被Q整除。

图2中示出的通信装置200的结构并不构成对通信装置的限定，实际的通信装置可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如下，为了阐述本申请实施例的资源分配方法，先介绍资源分配所基于的无线帧结构。图3为本申请实施例提供的一种5G NR-TDD无线帧结构示意图。5G NR支持多种无线帧结构，子载波间隔包括15KHz，30KHz，60KHz，120KHz，240Khz模式。在TDD帧结构中，一个TDD无线帧长度为10ms，分为10个子帧(未在图中示出)，子帧长度为1ms。当子载波间隔为30KHz时，一个TDD无线帧包括20个时隙，此时每个子帧包含两个时隙，每个时隙长度为0.5ms，5个时隙构成一个Pattern周期，时隙0-时隙4构成Pattern 1(P1) 周期，时隙5-时隙9构成Pattern 2(P2)周期，即一个Pattern周期长度为2.5ms。10个时隙(时隙0-时隙9)构成一组Pattern(P1+P2)周期。每个时隙由13个符号构成。可以理解的是，在不同无线帧结构中，由于子载波间隔是可变的，子载波间隔越大，则每个符号的时间长度越短，而在不同无线帧结构中，子帧长度固定为1ms，所以子载波间隔越大，则一个子帧所包含的符号越多，即图3中仅为示例性的给出一种TDD帧结构，可以理解的是本申请实施例所述的资源分配方法同样适用于其他帧结构。在5G NR-TDD无线帧的结构设计中，一个5G NR-TDD无线帧既可以用于传输上行信号又可以用于传输下行信号，即5G NR系统可以定义TDD上下行子帧配置。本申请实施例提供的资源分配方法中，示例性的，提供的一种5G NR-TDD上下行子帧配置，如图3所示，网状填充并写有“DL”的时隙表示用于下行链路(down link，DL)传输的时隙，网状填充的符号表示用于DL传输的符号；点状填充且写有“UL”的时隙表示用于上行链路(up link，UL)传输的时隙，点状填充的符号表示用于UL传输的符号；空白且写有字母“S”的时隙表示用于提供保护间隔或者提供数据传输的灵活(flexible slot)时隙(特殊时隙)，空白且写有字母“X”的符号表示用于提供保护间隔或者提供数据传输的灵活符号(特殊符号)(flexible symbol)，灵活符号为灵活时隙中的符号。如上述描述，时隙0-时隙2为下行时隙；时隙3-时隙4为灵活时隙；时隙5-时隙6为下行时隙；时隙7为灵活时隙；时隙8-时隙9为上行时隙。图3示例性的给出了时隙3，其中时隙3包括的13个符号中结尾连续两个符号为灵活符号，其余符号为下行符号；时隙4包括的13个符号中开始的连续两个符号为灵活符号，其余符号为上行符号；时隙7包括的13个符号中结尾连续4个符号为灵活符号，其余符号为下行符号。可以理解的是，图3中的5G NR-TDD上下行子帧配置仅为一种示例性的配置，也可以根据应用场景的配置不同种类的无线帧，和/或有不同的上下行配置，比如Pattern 1也可以全部为上行时隙，Pattern 2为混合时隙(包含上行时隙、灵活时隙和下行时隙)。本申请实施例对此不做具体限定。
本申请实施例提供一种资源分配的方法，以接入网设备为基站为例，如图4所示，该方法可以包括S101-S104：
S101、接入网设备确定资源指示信息。
具体的，上述资源指示信息用于指示SL的传输资源，SL的传输资源包括第一资源和/或第二资源，即SL传输资源包括第一资源，或者包括第二资源，或者包括第一资源和第二资源。该第一资源包括一个或多个第一时隙，该第二资源包括一个或多个第二时隙。其中，第一时隙中用于SL传输的符号数不同于第二时隙中用于SL传输的符号数。在一种可能的设计中，第一时隙中的全部符号用于SL传输，第二时隙中的部分符号用于SL传输。在另一种可能的设计中，每一第一时隙中的全部符号用于SL传输，每一第二时隙中的部分符号用于SL传输。比如，资源指示信息指示SL传输资源包括图3所示的时隙3的前4个符号，还可以包括时隙7的前3个符号。
如下介绍几种如何指示哪一时隙中哪一个或几个符号用于SL传输的具体实现方案：
方案1：在一种可能的实现方式中，上述资源指示信息包括第一SL资源位图(bitmap)，该第一SL资源位图中的比特位数为可用于SL传输的时隙数的P倍，P为正整数。
在本申请实施例中，可用于SL传输的时隙，指的是能够用于SL传输的时隙的集合，可以将这个集合中的时隙配置给终端进行SL通信使用，其中，配置给终端使用的时隙可 以为全部符号给终端使用，也可以为部分符号给终端使用。具体的，用于SL传输的时隙，可以是排除一些预留时隙、同步时隙、下行时隙等时隙之外的时隙。在一种可能的设计中，可用于SL传输的时隙只包括上行时隙。在另一种可能的设计中，可用于SL传输的时隙包括上行时隙和灵活时隙。
其中，若P为1，上述第一SL资源位图中的比特取值用于指示对应的时隙为全部符号用于SL传输或者部分符号用于SL传输；这种情况下，时隙的使用状态可以预配置在终端中或者通过信令由网络设备配置给终端。
需要说明的是，本申请实施例中通过信令由网络设备配置给终端为：网络设备通过无线资源控制(radio resource control，RRC)信令，媒体接入控制(Medium Access Control，MAC)信令或物理层信令中的至少一项发送给终端。本申请实施例中资源位图为bitmap。在此进行统一说明，下文涉及上述内容不再进行赘述。
若P为大于1的整数，上述第一SL资源位图中相邻P个比特取值用于指示对应的时隙中用于SL传输的符号的起始位置以及符号个数。其中，相邻P个比特包括第一SL资源位图中的第x至第x+(P-1)个比特，其中，x+(P-1)能被P整除。
在本申请实施例中，一个时隙中用于SL传输的符号的起始位置和符号个数，可以称为该时隙的使用状态或者配置状态，或者还可以为其他名称。在不同使用状态下，时隙中用于SL传输的符号起始位置不同，和/或，符号个数不同。比如，在一种使用状态下，时隙中用于传输SL传输的符号的起始位置是第一个符号，符号个数为3，在另一种使用状态下，时隙中用于传输SL传输的符号的起始位置是第二个符号，符号个数也为3。在本申请实施例中，同一时隙，可以配置相同的使用状态，或者不同的使用状态。类似的，可以为不同时隙配置相同或不同的使用状态。
如果有N(N为正整数)种使用状态，需要的用于表示N种使用状态的bit位为Y＝logN的上限。示例性的，当N为2时，只需要一比特即可表示slot的两种使用状态。如此，当第一资源位图中相邻P个比特表示一个使用状态时，P个比特总共能够指示的使用状态的个数为2^P。
其中，第一SL资源位图的bit长度可以称为第一SL资源位图的周期长度。当P＝1时，第一SL资源位图的周期长度可以为第一slot长度的倍数，或者第一slot长度为第一SL资源位图的周期长度的倍数。其中，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1或者Pattern 1+Pattern 2所表示的slot长度(如图3中所示的P1加P2的长度)中除去传输下行链路信号的时隙以及除去预留slot(并未在图3中示出)后剩余的部分slot的长度和。其中，倍数为正整数，预留slot指的是网络设备预先配置好的用于传输检测或者同步信息资源的slot。
也就是说，当系统中只配置了pattern 1时，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1所表示的slot长度中除去传输下行链路信号的时隙以及除去预留slot后剩余的部分slot的长度和；当系统中既配置了pattern 1又配置了pattern 2时，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1+Pattern 2所表示的slot长度中除去传输下行链路信号的时隙以及除去预留slot后剩余的部分slot的长度和。其中，该长度和为slot个数和。上述周期长度可以为第一slot长度的倍数，通常为几个第一slot长度形成一个可以周期性适用的SL传输的配置；或者上述周期长度能够被第 一slot长度整除(即第一slot长度为该周期长度的倍数)，通常为一个第一slot长度包含几个可以周期性适用的SL传输的配置。其中，用于SL传输的slot格式指示的RRC信令可以为基站通过系统信息块(System Message Block，SIB)指示的信令或者任何专有信令(dedicated signaling)。
可选的，当UL slot和UL symbol可以用于SL传输时，以图3中所示的无线帧结构为例，slot 8，slot 9为UL slot，因此，这两个slot可以用于SL传输，slot 4包含的符号中有UL symbol，所以slot 4也可以用于SL传输。因此图3中所示的一个无线帧中，从左至右依次对应的S，UL，UL，S，UL，UL(slot 4、slot 8、slot 9)这6个slot可以用于SL传输。所以，第一SL资源位图中的比特位数为6的P倍。示例性的，假设将这6个可用于SL传输的slot中，配置为第3个时隙和第5个时隙中的全部符号用于SL传输，第1、2、4和6个时隙中的部分符号用于SL传输。假设当某比特位＝1时，表示指示对应的时隙为全部符号用于SL传输；当某比特位＝0时，表示指示对应的时隙为部分符号用于SL传输。
那么，当P＝1时，第一SL资源位图中的比特位数为6，第一SL资源位图可以表示为001010。这种情况下，即P＝1时，时隙的使用状态可以预配置在终端中，即用于SL传输的部分符号可以预配置在终端中，比如预配置slot中最后4个symbol用于SL传输，或者单数的部分符号用于SL传输，比如第一、三、五个符号用于SL传输，双数的部分符号用于SL传输。也可以通过信令由网络设备配置给终端，当然，也可以有其他配置方式，本申请实施例对此不做具体限定。
当然，在实际实现中，也有可能比特位＝0时，表示指示对应的时隙为全部符号用于SL传输；当某比特位＝1时，表示指示对应的时隙为部分符号用于SL传输，本申请实施例对0、1具体表示的内容不做限定。
当P＝2时，第一SL资源位图中的比特位数为可用于SL传输的时隙数*P＝6*2＝12，其中，对于6个时隙中的每一时隙，均有两位比特用于指示该时隙的使用状态。假设00表示对应的slot的全部符号用于SL传输；01，10和11对应的slot的部分符号用于SL传输，比如，01指示对应slot的第一个符号至第四个符号用于SL传输，10指示对应slot的第二个符号至第四个符号用于SL传输，11指示对应slot的第一个符号至第六个符号用于SL传输。那么当使用第一SL资源位图表示上述6个用于SL传输的slot的使用状态时，第一SL资源位图可以为01 10 00 11 10 00。以这12比特中的前两个比特为例说明，前2个比特用于指示6个时隙中的第一个时隙的使用状态，即该第一个时隙中的第一个至第四个符号被配置用于SL传输。
当然，00、01、10、11具体分别指示什么使用状态，可以根据实际实现设置，本申请实施例这里不做限定。
需要说明的是，本申请实施例中，可以动态调整P值，从而可以指示不同数目的符号的使用状态。其中，P值较小时，基站向终端发送的资源指示信息的开销较小。P值较大时，可以指示时隙的更多使用状态，即能够更加精细化的指示时隙的使用状态，这样一来，可以有更多的终端资源配置方案，并且，为终端配置的资源可以是更细粒度的，便于满足不同终端的通信需求。
需要说明的是，上述已指出，第一资源位图中相邻P个比特位用于指示第一SL资源位图中对应的时隙使用状态，其中，相邻P个比特，并非相邻的任意相邻的P个比特。以 可用于SL传输的时隙数为6，P＝3为例，第一资源位图的形式为xxx xxx xxx xxx xxx xxx(x仅表示比特占位，并不表示具体数值，比如xxx也可能是001)，相邻P个比特包括所述第一SL资源位图中的第x至第x+(P-1)个比特，其中，x+(P-1)能被P整除，x为变量。x＝1时，从第一个比特位开始指示，第1至3(x＝1，x+(P-1)＝1+(3-1))个比特位用于指示第一个时隙的使用状态，类似的，x＝4时，第4至6(可以被P＝3整除)个比特位用于指示第二个时隙的使用状态，当x＝5时，x+(P-1)＝7，7不能被3整除。可见，相邻P个比特是否能够用于指示对应时隙的使用状态，与该相邻时隙中最后一个比特在第一资源位图中的位置有关。
可选的，当UL slot、UL symbol和灵活symbol可以用于SL传输时，参见图3中所示，slot 8，slot 9为UL slot可以用于SL传输，slot 4包含有UL symbol和灵活symbol可以用于SL传输，slot 3和slot 7包含有灵活symbol可以用于SL传输。因此图3中所示的一个无线帧中，从左至右依次对应的S，S，S，UL，UL，S，S，S，UL，UL(slot 3、slot 4、slot 7、slot 8、slot 9)这10个slot可以用于SL传输，所以，第一SL资源位图中的比特位数为10的P倍。示例性的，假设这10个可用于SL传输的slot中，第5个时隙和第9个时隙中的全部符号用于SL传输，剩余时隙中的部分符号用于SL传输。那么，当P＝1时，第一SL资源位图中的比特位数为10，假设当某比特位＝1时，表示指示对应的时隙为全部符号用于SL传输；当某比特位＝0时，表示指示对应的时隙为部分符号用于SL传输。那么，第一SL资源位图可以表示为0000100010。当P＝2时，第一SL资源位图中的比特位数为20，对应的slot使用状态有四种，分别通过00，01，10，11来标识不同的slot使用状态。如上文所述，可以将00表示对应的slot的全部符号用于SL传输；01，10和11对应的slot的部分符号用于SL传输，分别对应相同或不同的用于SL传输的符号的起始位置以及符号个数。那么上述10个用于SL传输的slot使用状态用第一SL资源位图表示，此时，第一SL资源位图可以为10 01 10 01 00 11 10 11 00 11。
方案2：在另一种可能的实现方式中，上述资源指示信息除了包括第一SL资源位图，还包括第二SL资源位图。其中，第一SL资源位图中的比特位数为可用于SL传输的时隙数的P倍，P为正整数。第二SL资源位图中的比特位数为可用于SL传输的时隙数的Q倍，Q为正整数。
与上述方案类似，第一SL资源位图中的比特取值用于指示对应的时隙是否全部符号用于SL传输。若Q为1，第二SL资源位图中的比特取值用于指示对应的时隙是否部分符号用于SL传输；若Q为大于1的整数，第二SL资源位图中相邻Q个比特取值用于指示对应的时隙中用于SL传输的符号的起始位置以及符号个数，所述相邻Q个比特包括所述第二SL资源位图中的第y至第y+(Q-1)个比特，其中，y+(Q-1)能被Q整除。
需要说明的是，本申请实施例中，可以动态调整Q值，从而可以指示不同数目的符号的使用状态。其中，Q值较小时，基站向终端发送的资源指示信息的开销较小。Q值较大时，可以指示时隙的更多使用状态，即能够更加精细化的指示时隙的使用状态，这样一来，可以有更多的终端资源配置方案，并且，为终端配置的资源可以是更细粒度的，便于满足不同终端的通信需求。
需要说明的是，上述已指出，第二资源位图中相邻Q个比特位用于指示用于SL传输的时隙数，其中，相邻Q个比特，并非相邻的任意相邻的Q个比特。以可用于SL传输的 时隙数为6，Q＝3为例，第二资源位图的形式为yyy yyy yyy yyy yyy yyy(y仅表示比特占位，并不表示具体数值，比如yyy也可能是001)，相邻Q个比特包括所述第二SL资源位图中的第y至第y+(Q-1)个比特，其中，y+(Q-1)能被Q整除，y为变量。y＝1时，从第一个比特位开始指示，第1至3(y＝1，y+(Q-1)＝1+(3-1)＝3)个比特位用于指示第一个时隙的使用状态，类似的，y＝4时，第4至6(可以被Q＝3整除)个比特位用于指示第二个时隙的使用状态，当y＝5时，y+(Q-1)＝7，7不能被3整除。可见，相邻Q个比特是否能够用于指示对应时隙的使用状态，与该相邻时隙中最后一个比特在第二资源位图中的位置有关。
在本申请实施例中，一个时隙中用于SL传输的符号的起始位置和符号个数，可以称为该时隙的使用状态或者配置状态，或者还可以为其他名称。在不同使用状态下，时隙中用于SL传输的符号起始位置不同，和/或，符号个数不同。如果有N(N为正整数)种使用状态，需要的用于表示N种使用状态的bit位为Y＝logN的上限。示例性的，当N为2时，只需要一比特即可表示slot的两种使用状态。如此，当第二资源位图中相邻Q个比特表示一个使用状态时，Q个比特总共能够指示的使用状态的个数为2^Q。
其中，第一SL资源位图与第二SL资源位图的bit长度一样或不一样。第一SL资源位图的bit长度还可以称为第一SL资源位图的周期长度，第二SL资源位图的bit长度还可以称为第二SL资源位图的周期长度，这里统一说明，下文不再赘述。
当P＝1，Q＝1时，第一SL资源位图和第二SL资源位图的周期长度可以为第一slot长度的倍数，或者第一slot长度为该周期长度的倍数。其中，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1或者Pattern 1+Pattern 2所表示的slot长度(如图3中所示的P1加P2的长度)中除去传输下行链路信号的时隙以及除去预留slot(并未在图3中示出)后剩余的部分slot的长度和。其中，倍数为正整数，预留slot指的是网络设备预先配置好的用于传输检测或者同步信息资源的slot。
也就是说，当系统中只配置了pattern 1时，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1所表示的slot长度中除去传输下行链路信号的时隙以及除去预留slot后剩余的部分slot的长度和；当系统中既配置了pattern 1又配置了pattern 2时，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1+Pattern 2所表示的slot长度中除去传输下行链路信号的时隙以及除去预留slot后剩余的部分slot的长度和。其中，该长度和为slot个数和。上述周期长度可以为第一slot长度的倍数，通常为几个第一slot长度形成一个可以周期性适用的SL传输的配置；或者上述周期长度能够被第一slot长度整除(即第一slot长度为该周期长度的倍数)，通常为一个第一slot长度包含几个可以周期性适用的SL传输的配置。其中，用于SL传输的slot格式指示的RRC信令可以为基站通过系统信息块(System Message Block，SIB)指示的信令或者任何专有信令(dedicated signaling)。
可选的，当UL slot和UL symbol可以用于SL传输时，参见图3中所示，slot 8，slot 9为UL slot可以用于SL传输，slot 4包含的符号中有UL symbol，所以slot 4也可以用于SL传输。因此图3中所示的一个无线帧对应的S，UL，UL，S，UL，UL(slot 4、slot 8、slot 9)这6个slot可以用于SL传输。所以，第一SL资源位图中的比特位数为6的P倍，第二SL资源位图中的比特位数为6的Q倍。示例性的，假设这6个可用于SL传输的slot 中，配置为第3个时隙和第5个时隙中的全部符号用于SL传输，第2个时隙和第4个时隙中的部分符号用于SL传输。那么，当P＝1，Q＝1时，第一SL资源位图中的比特位数为6，第二SL资源位图中的比特位数为6。假设当某比特位＝1时，表示“是”的含义，即指示对应的时隙为全部符号用于SL传输或指示对应的时隙为部分符号用于SL传输；当某比特位＝0时，表示“否”的含义，即指示对应的时隙不是全部符号用于SL传输或对应的时隙不是部分符号用于SL传输。那么，第一SL资源位图可以表示为001010，第二SL资源位图可以表示为010100。此种情况下，当某一时隙的部分符号用于SL传输时，具体使用时隙中的哪部分符号，可以预先配置在终端中。
当P＝1，Q＝2时，第一SL资源位图不变仍表示为001010，第二SL资源位图中的比特位数为6*2＝12，其中，两个比特可以指示一个时隙的使用状态，两个比特总共能够指示slot的四种使用状态。那么上述6个用于SL传输的slot中，第2个时隙和第4个时隙中的部分符号用于SL传输的使用状态可以用第二SL资源位图表示，此时，第二SL资源位图可以为00 10 00 00 10 00。其中，第二资源位图中的00、10分别指示时隙的不同使用状。
可选的，当UL slot、UL symbol和灵活symbol可以用于SL传输时，参见图3中所示，slot 8，slot 9为UL slot可以用于SL传输，slot 4包含有UL symbol和灵活symbol可以用于SL传输，slot 3和slot 7包含有灵活symbol可以用于SL传输。因此图3中所示的一个无线帧对应的S，S，S，UL，UL，S，S，S，UL，UL(slot 3、slot 4、slot 7、slot 8、slot 9)这10个slot可以用于SL传输。所以，第一SL资源位图中的比特位数为10的P倍，第二SL资源位图中的比特位数为10的Q倍。示例性的，假设这10个可用于SL传输的slot中，第5个时隙和第9个时隙中的全部符号用于SL传输，第1、4、6、8个时隙中的部分符号用于SL传输。那么，当P＝1，Q＝1时，第一SL资源位图中的比特位数为10，第二SL资源位图中的比特位数为10。假设当某比特位＝1时，表示“是”的含义，即指示对应的时隙为全部符号用于SL传输或指示对应的时隙为部分符号用于SL传输；当某比特位＝0时，表示“否”的含义，即指示对应的时隙不是全部符号用于SL传输或对应的时隙不是部分符号用于SL传输。那么，第一SL资源位图可以表示为0000100010，第二SL资源位图可以表示为1001010100。当P＝1，Q＝2时，第一SL资源位图不变仍表示为0000100010，第二SL资源位图中的比特位数为10*2＝20，那么上述6个用于SL传输的slot中第1、4、6、8个时隙中的部分符号用于SL传输的使用状态用第二SL资源位图表示，此时，第二SL资源位图可以为10 00 00 01 00 11 00 11 00 00。
方案3：在另一种可能的实现方式中，上述资源指示信息包括第一SL资源位图和第二SL资源位图。其中，第一SL资源位图中的比特位数为可用于SL传输的时隙数的P倍，P为正整数。第二SL资源位图中的比特位数为配置为用于SL传输的时隙数的R倍，R为正整数。
第一SL资源位图中的比特取值用于指示对应的时隙是否配置为用于SL传输。若R为1，第二SL资源位图中的比特取值用于指示配置为用于SL传输的时隙是否部分符号用于SL传输；若R为大于1的整数，第二SL资源位图中相邻R个比特取值用于指示对应的时隙中用于SL传输的符号的起始位置以及符号个数，相邻R个比特包括第二SL资源位图中的第z至第z+(R-1)个比特，其中，z+(R-1)能被R整除。
需要说明的是，本申请实施例中，可以动态调整R值，从而可以指示不同数目的符号 的使用状态。其中，R值较小时，基站向终端发送的资源指示信息的开销较小。R值较大时，可以指示时隙的更多使用状态，即能够更加精细化的指示时隙的使用状态，这样一来，可以有更多的终端资源配置方案，并且，为终端配置的资源可以是更细粒度的，便于满足不同终端的通信需求。
需要说明的是，上述已指出，第二资源位图中相邻R个比特位用于指示配置为用于SL传输的时隙数，其中，相邻R个比特，并非相邻的任意相邻的R个比特。以可用于SL传输的时隙数为6，R＝3为例，第二资源位图的形式为zzz zzz zzz zzz zzz zzz(z仅表示比特占位，并不表示具体数值，比如zzz也可能是001)，相邻R个比特包括所述第二SL资源位图中的第z至第z+(R-1)个比特，其中，z+(R-1)能被R整除，z为变量。z＝1时，从第一个比特位开始指示，第1至3(z＝1，z+(R-1)＝1+(3-1)＝3)个比特位用于指示第一个时隙的使用状态，类似的，z＝4时，第4至6(可以被R＝3整除)个比特位用于指示第二个时隙的使用状态，当z＝5时，z+(R-1)＝7，7不能被3整除。可见，相邻R个比特是否能够用于指示对应时隙的使用状态，与该相邻时隙中最后一个比特在第二资源位图中的位置有关。
在本申请实施例中，一个时隙中用于SL传输的符号的起始位置和符号个数，可以称为该时隙的使用状态或者配置状态，或者还可以为其他名称。在不同使用状态下，时隙中用于SL传输的符号起始位置不同，和/或，符号个数不同。如果有N(N为正整数)种使用状态，需要的用于表示N种使用状态的bit位为Y＝logN的上限。示例性的，当N为2时，只需要一比特即可表示slot的两种使用状态。如此，当第二资源位图中相邻R个比特表示一个使用状态时，R个比特总共能够指示的使用状态的个数为2^R。
具体的，第一SL资源位图中被配置为用于SL传输的slot既有整个slot(包含该slot中全部符号)用于SL传输的slot，也有该slot中部分符号(仅包含该slot中的部分符号)用于SL传输的slot。第二SL资源位图用于进一步指示第一SL资源位图中被配置用于SL传输的slot中每个被配置用于SL传输的slot中具体哪些符号用于SL传输。作为一种示例，第二SL资源位图用于进一步指示第一SL资源位图中所有被配置用于SL传输的slot中，哪些slot是全部符号用于SL传输，或者哪些slot是该slot中的部分符号用于SL传输。当第二SL资源位图指示的是哪些slot是该slot中的部分符号用于SL传输时，意味着第一SL资源位图中被指示用于SL的剩余slot是全部符号用于SL传输。第一SL资源位图与第二SL资源位图的bit长度一样或者不一样。第一SL资源位图的bit长度也可以称为第一SL资源位图的周期长度，第二SL资源位图的bit长度也可以称为第二SL资源位图的周期长度。
第一SL资源位图的周期长度可以为第一slot长度的倍数，或者第一slot长度为该周期长度的倍数。其中，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1或者Pattern 1+Pattern 2所表示的slot长度(如图3中所示的P1加P2的长度)中除去传输下行链路信号的时隙以及除去预留slot(并未在图3中示出)后剩余的部分slot的长度和。其中，倍数为正整数，预留slot指的是网络设备预先配置好的用于传输检测或者同步信息资源的slot。
也就是说，当系统中只配置了pattern 1时，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1所表示的slot长度中除去传输下行链路信号的时隙以及除去 预留slot后剩余的部分slot的长度和；当系统中既配置了pattern 1又配置了pattern 2时，第一slot长度为现有5G系统中通过common的RRC信令配置的Pattern 1+Pattern 2所表示的slot长度中除去传输下行链路信号的时隙以及除去预留slot后剩余的部分slot的长度和。其中，该长度和为slot个数和。上述周期长度可以为第一slot长度的倍数，通常为几个第一slot长度形成一个可以周期性适用的SL传输的配置；或者上述周期长度能够被第一slot长度整除(即第一slot长度为该周期长度的倍数)，通常为一个第一slot长度包含几个可以周期性适用的SL传输的配置。其中，用于SL传输的slot格式指示的RRC信令可以为基站通过系统信息块(System Message Block，SIB)指示的信令或者任何专有信令(dedicated signaling)。
可选的，当UL slot和UL symbol可以用于SL传输时，参见图3中所示的应用场景，slot 8，slot 9为UL slot可以用于SL传输，slot 4包含的符号中有UL symbol，所以slot 4也可以用于SL传输。因此图3中所示的一个无线帧对应的S，UL，UL，S，UL，UL(slot 4、slot 8、slot 9)这6个slot可以用于SL传输。示例性的，假设这6个可用于SL传输的slot中，有4个slot配置为用于SL传输的slot，其中，第3个时隙和第5个时隙中的全部符号用于SL传输，第2个时隙和第4个时隙中的部分符号用于SL传输。所以，第一SL资源位图中的比特位数为6的P倍，第二SL资源位图中的比特位数为4的R倍。
那么，当P＝1，R＝1时，第一SL资源位图中的比特位数为6，第二SL资源位图中的比特位数为4，假设当某比特位＝1时，表示“是”的含义，即指示第一SL资源位图中对应的时隙配置为用于SL传输或指示第二SL资源位图中对应的时隙为部分符号用于SL传输；当某比特位＝0时，表示“否”的含义，即指示第一SL资源位图中对应的时隙未配置为用于SL传输或指示第二SL资源位图中对应的时隙不是部分符号用于SL传输。那么，第一SL资源位图可以表示为011110，意味着第二至四个时隙均被配置为用于SL传输，第二SL资源位图可以表示为1010(第2个时隙为配置为用于SL传输的时隙中的第1个时隙，其为部分符号用于SL传输的时隙，故第二SL资源位图中的第一个bit位用1表示)。这种情况下，第二SL资源位图中标记为0的比特位可以指示该slot中的符号全部用于SL传输，还可以指示该slot中的符号是部分符号用于SL传输但是以另一种不同的配置方式用于SL传输。当然，第一资源位图与第二资源位图中0和1的含义还可以分别为其他，比如，第一资源位图中某比特位＝1时，指示对应的时隙配置为用于SL传输，当某比特位＝0时，指示对应的时隙未配置为用于SL传输。第二资源位图中某比特为0时，指示对应的时隙为部分符号用于SL传输；比特为1，指示对应的时隙不是部分符号用于SL传输。
当P＝1，R＝2时，第一SL资源位图不变仍表示为011110，第二SL资源位图中的比特位数为8，对应的slot使用状态有四种，分别通过00，01，10，11来标识不同的slot使用状态。可以将00表示对应的slot不是部分符号用于SL传输(由于第二SL资源位图只用于指示对应的slot中部分符号用于SL传输时的使用状态，故，其他非部分符号用于SL传输的slot可以利用其他SL资源位图指示)或者00表示对应的slot是该slot中全部符号用于SL传输；01，10和11对应的slot的部分符号用于SL传输，分别对应相同或不同的用于SL传输的符号的起始位置以及符号个数。那么上述4个配置为用于SL传输的slot中第2个时隙和第4个时隙中的部分符号用于SL传输的使用状态用第二SL资源位图表示，此时，第二SL资源位图可以为10 00 01 00。
可选的，当UL slot、UL symbol和灵活symbol可以用于SL传输时，参见图3中所示的应用场景，slot 8，slot 9为UL slot可以用于SL传输，slot 4包含有UL symbol和灵活symbol可以用于SL传输，slot 3和slot 7包含有灵活symbol可以用于SL传输。因此图3中所示的一个无线帧对应的S，S，S，UL，UL，S，S，S，UL，UL(slot 3、slot 4、slot 7、slot 8、slot 9)这10个slot可以用于SL传输。示例性的，假设这10个可用于SL传输的slot中，有6个slot配置为用于SL传输的slot，其中，第5个时隙和第9个时隙中的全部符号用于SL传输，第1、4、6、8个时隙中的部分符号用于SL传输。所以，第一SL资源位图中的比特位数为10的P倍，第二SL资源位图中的比特位数为6的R倍。那么，当P＝1，R＝1时，第一SL资源位图中的比特位数为10，第二SL资源位图中的比特位数为6，假设当某比特位＝1时，表示“是”的含义，即指示对应的时隙配置为用于SL传输或指示对应的时隙为部分符号用于SL传输；当某比特位＝0时，表示“否”的含义，即指示对应的时隙未配置为用于SL传输或对应的时隙不是部分符号用于SL传输。那么，第一SL资源位图可以表示为1001110110，第二SL资源位图可以表示为110110。当P＝1，Q＝2时，第一SL资源位图不变仍表示为1001110110，第二SL资源位图中的比特位数为12，对应的slot使用状态有四种，分别通过00，01，10，11来标识不同的slot使用状态。可以将00表示对应的slot不是部分符号用于SL传输(由于第二SL资源位图只用于指示对应的slot中部分符号用于SL传输时的使用状态，故，其他非部分符号用于SL传输的slot可以利用其他SL资源位图指示)；01，10和11对应的slot的部分符号用于SL传输，分别对应相同或不同的用于SL传输的符号的起始位置以及符号个数。那么上述6个用于SL传输的slot中第1、4、6、8个时隙中的部分符号用于SL传输的使用状态用第二SL资源位图表示，此时，第二SL资源位图可以为10 01 00 11 01 00。
S102、接入网设备向终端设备发送资源指示信息。
接入网设备通过将上述资源指示信息发送给设备终端，使得设备终端明确可以用于SL传输的资源，以使用该资源进行后续的SL传输。具体的，接入网设备向终端设备发送第一信令，该第一信令包括上述资源指示信息，第一信令包括RRC信令、MAC信令、或物理层信令中的至少一种。使得终端设备可以按照第一信令所指示的资源进行配置SL传输资源用于SL传输。并且，接入网设备还可以根据当前网络状态等信息，确定不同的资源指示信息，灵活实时的为不同的终端设备指示用于SL传输的资源，提高传输效率。
S103、终端设备获取资源指示信息。
具体的，终端设备从接入网设备接收资源指示信息，或者该资源指示信息为预配置的资源指示信息。其中，预配置的指的是通过预先写好在终端设备，或者通过操作维护管理(operation administration and maintenance，OAM)配置给终端设备。
需要说明的是，当终端设备通过预配置方式获取资源指示信息时，上述S101、S102为可选步骤，即可以不执行S101、S102。
当然，终端设备还可以预配置资源指示信息中的一部分，并通过基站获取资源指示信息中的另一部分。比如，在方案1中，终端从基站接收包括001010的资源指示信息，用于指示地1、2、4、6个时隙中每一时隙的部分符号用于SL传输。第3、5个时隙中的全部符号用于SL传输。其中，具体部分符号指的是哪些符号，可以预配置在终端中。比如，终端预配置时隙中的第一至第四个符号用于SL传输。则终端仅需通过基站接收6比特信 息，就可以获知具体使用哪些符号进行SL传输。终端无需从基站获取关于部分符号的起始位置和符号个数的具体指示，节约了基站向终端发送信令的开销，能够提升网络的资源利用率。
当然，终端还可以从基站获取关于部分符号的起始位置和符号个数的具体指示，这种方式中，基站可以根据当前网络的通信状况，比如通信质量，不同终端的不同通信需求，灵活实时的为不同终端指示相同或不同的部分符号的起始位置和符号个数，如此，能够更加契合终端的通信需求，满足终端的服务差异化需求，提升终端的通信质量。
S104、终端设备基于资源指示信息进行SL传输。
具体的，利用获取的资源指示信息进行SL传输资源的配置，进而进行SL传输。
本申请提供的一种资源分配方法，接入网设备确定资源指示信息，该资源指示信息用于指示SL的传输资源，SL的传输资源包括第一资源和/或第二资源，第一资源包括一个或多个第一时隙，第二资源包括一个或多个第二时隙。其中，第一时隙中用于SL传输的符号数不同于第二时隙中用于SL传输的符号数。接入网设备向终端设备发送资源指示信息。如此，为终端配置的用于SL传输的资源可以是整个时隙，也可以是时隙中的某一个或一些符号，使得资源配置粒度更加精细化，以便于可以更加灵活的配置终端设备中用于SL传输的资源，提高终端设备传输SL资源的效率。
本申请实施例提供一种资源分配的方法，以接入网设备为基站为例，参见图5，该方法可以包括S201-S204：
S201、接入网设备确定资源指示信息。
本申请实施例中，资源指示信息也可以称为配置信息，接入网设备确定的资源指示信息包括第一信息，该第一信息用于指示配置为用于SL传输的时隙和/或符号。具体的，第一信息用于指示配置为用于SL传输的时隙和/或符号的位置，和/或第一信息用于指示配置为用于SL传输的时隙和/或符号的长度。其中，配置为用于SL传输的时隙和/或符号的位置也可以称为配置为用于SL传输的时隙和/或符号的分布，该位置可以通过隐示指示，或者显示指示。当为隐示指示时，可以通过mode标识隐性地通知配置为用于SL传输的时隙和/或符号的位置的含义。配置为用于SL传输的时隙和/或符号的长度即为配置为用于SL传输的时隙和/或符号的数量。
其中，配置为用于SL传输的时隙和/或符号为可用于SL传输的时隙的子集。其中，可用于SL传输的时隙包括上行符号，或者，包括灵活符号，或者，包括上行符号和第一符号，或者，包括灵活符号和第一符号，或者，包括灵活符号、上行符号和第一符号。其中，灵活符号在可用于SL传输的时隙的位置和长度可预先配置或者通过信令进行配置。其中，通过信令进行配置为网络设备通过RRC信令，MAC信令，或物理层信令中至少一种进行配置通知给用户设备。第一符号为下行符号或者预配置的用于传输其它资源的符号，比如同步资源或者预留资源等。
需要说明的是，本申请实施例中，UL时隙也可以认为是UL符号对应的一个slot的所有符号都用于UL传输，同样，灵活时隙也可以认为是灵活符号对应的一个slot的所有符号都用于灵活传输。当然，也可以认为UL时隙和UL符号是分别的用slot和symbol来表示；灵活时隙和灵活符号是分别的用slot和symbol来表示。
如下介绍几种资源指示信息的内容或者资源指示信息中所包含的如何指示哪几个时 隙或者哪一时隙中哪一个或几个符号用于SL传输的具体实现方案。资源指示信息可以是通过RRC信令指示配置为SL传输的时隙和/符号的位置及数量。RRC信令沿用目前common/dedicated-TDD-configuration的基本指示，但需要增加SL slots和/或SL symbols指示等第一信息以通知用于SL传输的资源。
方案1：在一种可能的实现方式中，对于不同的实施场景可以定义不同的模式(mode)以指示对应时隙和/或符号的配置状态(或称使用状态)。比如，对于UL slot和UL symbol可以用于SL传输实施场景，定义mode 1，对于UL slot、UL symbol、灵活slot和灵活symbol可以用于SL传输的实施场景，定义mode 2，或mode 3中一种或者多种的组合。进一步，可以在mode 1下针对不同配置状态对应的用于SL传输的时隙或符号的位置重新定义mode1.1，mode1.2，可以在mode 2下针对不同配置状态对应的用于SL传输的时隙或符号的位置重新定义mode 2.1，mode 2.2，2.3，2.4…。在上述RRC信令指示中指示每种标注mode下用于SL传输的时隙或符号的位置和长度的标示，从而使得当RRC信令下发给终端设备时，终端设备能够根据mode的标示理解其中所包含的SL slot或SL symbol的含义，正确解读该用于指示用于SL传输的时隙或符号的位置和长度的RRC信令。
如下结合图6具体阐述第一信息如何指示配置为用于SL传输的时隙和/或符号的位置和长度，示例性的给出了8个时隙，slot 0-slot 7，slot 2示例性的给出了包含的13个symbol。其中，网格状填充的时隙(J1)表示用于传输下行链路信号的时隙，网状填充的符号(K1)表示用于传输下行链路信号的符号；空白的符号(K2)表示用于提供保护间隔或者提供数据传输的灵活符号(特殊符号)；斜线填充的时隙(J2’)表示用于传输侧行链路信号的时隙；点状填充的时隙(J2)表示用于传输上行链路信号的时隙，点状填充的符号(K3)表示用于传输上行链路信号的符号。其中，J1包含2个DL slot，K1包含4个DL symbol，K2包含4个flexible symbol，K3包含5个UL symbol，J2’包含2个SL slot，J2包含3个UL slot。
首先，定义模式，比如，定义如下模式1：
Mode 1：UL slot和UL symbol可以用于SL传输；
其次，在UL slot和UL symbol可以用于SL传输的模式1下，定义配置为用于SL传输的时隙的位置和长度，比如，定义如下位置和长度的SL时隙：
Mode1.1：定义J2’(SL slot)在UL symbol的结尾；
具体的，本申请实施例利用如下格式的第一信息确定帧的具体结构，以便于确定J2’的具体位置：
->J1(DL slot，UU)，K1(DL symbol，UU)，…(FFF…)，K3(UL symbol，UU)，J2’(SL slot)，J2(UL slot，UU)；
其中，J1(DL slot，UU)为用于DL传输的slot个数，K1(DL symbol，UU)为用于DL传输的symbol个数，K3(UL symbol，UU)为用于UL传输的symbol个数，J2’(SL slot)为用于SL传输的slot个数，J2(UL slot，UU)为用于UL传输的slot个数；并且用于SL传输的slot位于用于UL传输的symbol之后，位于用于UL传输的slot之前。
具体的，结合图6，第一信息可以如下：
->J1(DL slot，UU)，K1(DL symbol，UU)，K2(flexible symbol，UU)，K3(UL symbol，UU)，J2’(SL slot)，J2(UL slot，UU)；
即，NR下终端设备UU接口的资源分配方式为：在K3上行符号结束位置之后的符号或时隙，可以配置为用于SL传输的符号或时隙。那么，配置为用于SL传输的符号或时隙长度，可以由J2’的长度数值得出。
当然，在UL slot和UL symbol可以用于SL传输的模式1下，还可以定义在帧结构中处于如下位置的SL时隙，参见图7所示(图7中各个字母的含义与图6中相同)：
Mode1.2：定义J2’(SL slot)在UL slot的结尾；
->J1(DL slot，UU)，K1(DL symbol，UU)，…(FFF…)，K3(UL symbol，UU)，J2(UL slot，UU)，J2’(SL slot)；

->J1(DL slot，UU)，K1(DL symbol，UU)，K2(flexible symbol，UU)，K3(UL symbol，UU)，J2(UL slot，UU)，J2’(SL slot)；
即，NR下终端设备UU接口的资源分配方式为：在J2上行时隙结束位置之后的符号或时隙，可以配置为SL传输的符号或时隙，并且，配置为用于SL传输的符号或时隙长度，可以由J2’的长度数值得出。
可见，在同一模式下，即在UL slot和UL symbol可以用于SL传输的模式下，可以有相同或不同的SL时隙使用状态，即用于SL传输的时隙的起始位置和时隙长度可能相同或不同。
类似的，可以定义其他模式，比如，定义UL slot、UL symbol和flexible symbol可以用于SL传输的如下模式。
如下结合图8具体阐述第一信息如何指示配置为用于SL传输的时隙和/或符号的位置和长度，示例性的给出了11个时隙，slot 0-slot 10，slot 2和slot 5示例性的给出了包含的13个symbol。其中，网格状填充的时隙(J1)表示用于传输下行链路信号的时隙，网状填充的符号(K1)表示用于传输下行链路信号的符号；斜线填充的符号(L1)表示用于传输侧行链路信号的符号；斜线填充的时隙(M1和J2’)表示用于传输侧行链路信号的时隙；空白的符号(K2)表示用于提供保护间隔或者提供数据传输的灵活符号(特殊符号)；点状填充的符号(K3)表示用于传输上行链路信号的符号；点状填充的时隙(J2)表示用于传输上行链路信号的时隙。其中，J1包含2个DL slot，K1包含4个DL symbol，L1包含9个SL symbol，M1包含2个SL slot，K2包含8个flexible symbol，K3包含5个UL symbol，J2’包含2个SL slot，J2包含3个UL slot。

其次，在UL slot、UL symbol和flexible symbol可以用于SL传输的模式2下，定义用于指示SL传输的时隙的位置和长度，比如，定义如下位置和长度的SL时隙：
Mode 2.1：定义L1(F symbols)，M1(SL slots)，以及J2’(SL slot)位于UL slots的开始处；
->J1(DL slot，UU)，K1(DL symbol，UU)，L1(F symbols)，M1(SL slots)，…(FFF…)，K3(UL symbol，UU)，J2’(SL slot)，J2(UL slot，UU)；
其中，J1(DL slot，UU)为用于DL传输的slot个数，K1(DL symbol，UU)为用于DL传输的symbol个数，L1(F symbols)为灵活符号个数(表示可以存在于资源指示信息，也可以不存在，当不存在时，一个周期长度((Pattern 1所表示的slot长度(P1)或Pattern 1+Pattern 2所表示的slot长度(P1+P2)))减去所有的slot以及symbol个数的指示所剩余的就是灵活符号个数)，K3(UL symbol，UU)为用于UL传输的symbol个数，J2(UL slot，UU)为用于UL传输的slot个数，J2’(SL slot)为用于SL传输的slot个数，M1(SL slots)为用于SL传输的slot个数；其中，用于SL传输的M1(SL slots)位于用于UL传输的symbol之前，具体为用于UL传输的symbol与flexible symbol(即，FFF…)补足一个slot之前，用于SL传输的J2’(SL slot)位于用于UL传输的symbol之后，及用于UL传输的slot之前。
其中，F symbols的位置及数量由DL symbol的位置及数量决定，用于补足一个完整的时隙，那么在图8中，SL slots(M1)位于F symbols(L1)之后，具体的，第一信息可以如下：
->J1(DL slot，UU)，K1(DL symbol，UU)，L1(F symbols)，M1(SL slots)，K2(flexible symbol，UU)，K3(UL symbol，UU)，J2’(SL slot)，J2(UL slot，UU)；
即，NR下终端设备UU接口的资源分配方式为：在K3上行符号结束位置之后的时隙J2’，可以配置为用于SL传输的时隙，K1下行符号所在时隙的剩余符号可以配置为用于SL传输的符号L1，与L1相邻的时隙可以配置为用于SL传输的时隙M1。那么，配置为用于SL传输的符号或时隙长度，可以由M1、J2’的长度数值得出。
当然，F symbols的位置及数量也可以由UL symbol的位置及数量决定，用于补足一个完整的时隙，那么在图9中，SL slots(M2)位于F symbols(L2)开始处，具体的，由于符号数量的变化，重新定义如下位置和长度的SL时隙：
Mode 2.2：定义M2(SL slots)，L2(F symbols)，以及J2’(SL slot)位于UL slots的开始处；
->J1(DL slot，UU)，K1(DL symbol，UU)，…(FFF…)，M2(SL slots)，L2(F symbols)，K3(UL symbol，UU)，J2’(SL slot)，J2(UL slot，UU)；
其中，J1(DL slot，UU)为用于DL传输的slot个数，K1(DL symbol，UU)为用于DL传输的symbol个数，L2(F symbols)为灵活符号个数(表示可以存在于第一信息，也可以不存在，当不存在时，一个周期长度(P1或P1+P2)减去所有的slot以及symbol个数的指示所剩余的就是灵活符号个数)，K3(UL symbol，UU)为用于UL传输的symbol个数，J2(UL slot，UU)为用于UL传输的slot个数，J2’(SL slot)为用于SL传输的slot个数，M2(SL slots)为用于SL传输的slot个数；其中，用于SL传输的M2(SL slots)位于用于UL传输的symbol之前，具体为用于UL传输的symbol与L2(F symbols)之前，用于SL传输的J2’(SL slot)位于用于UL传输的symbol之后，及用于UL传输的slot之前。
其中，示例性的，定义K2＝9，M2＝2，L2＝8，那么，结合图9，第一信息如下：
->J1(DL slot，UU)，K1(DL symbol，UU)，K2(flexible symbol，UU)，M2(SL slots)，L2(F symbols)，K3(UL symbol，UU)，J2’(SL slot)，J2(UL slot，UU)；
即，NR下终端设备UU接口的资源分配方式为：在K3上行符号结束位置之后的时隙 J2’，可以配置为用于SL传输的时隙，K3上行符号所在时隙的剩余符号可以配置为用于SL传输的符号L2，与L2相邻的时隙可以配置为用于SL传输的时隙M2。那么，配置为用于SL传输的符号或时隙长度，可以由M2、J2’的长度数值得出。
当然，在UL slot、UL symbol和flexible symbol可以用于SL传输的模式2下，还可以定义在帧结构中处于如下位置的SL时隙，参见图10所示(图10中各个字母的含义与图8中相同)：
Mode 2.3：定义L1(F symbols)，M1(SL slots)，以及J2’(SL slot)位于UL slots的结尾处；

其中，J1(DL slot，UU)为用于DL传输的slot个数，K1(DL symbol，UU)为用于DL传输的symbol个数，L1(F symbols)为灵活符号个数(表示可以存在于第一信息，也可以不存在，当不存在时，一个周期长度(Pattern 1所表示的slot长度(P1)或Pattern 1+Pattern 2所表示的slot长度(P1+P2))减去所有的slot以及symbol个数的指示所剩余的就是灵活符号个数)，K3(UL symbol，UU)为用于UL传输的symbol个数，J2(UL slot，UU)为用于UL传输的slot个数，J2’(SL slot)为用于SL传输的slot个数，M1(SL slots)为用于SL传输的slot个数；其中，用于SL传输的M1(SL slots)位于用于UL传输的symbol之前，具体为用于UL传输的symbol与flexible symbol(即，FFF…)补足一个slot之前，用于SL传输的J2’(SL slot)位于用于UL传输的slot之后。
其中，上述flexible symbol(即，FFF…)的数量不需要指明，鉴于用于补足一个完整的时隙，隐性的根据K3与一个slot所包含的symbol之差就可以获知。在图10中，SL slots(M1)位于F symbols(L1)之后，具体的，如Mode2.3中所示位置的时隙可以具体用如下第一信息指示：
->J1(DL slot，UU)，K1(DL symbol，UU)，L1(F symbols)，M1(SL slots)，K2(flexible symbol，UU)，K3(UL symbol，UU)，J2(UL slot，UU)，J2’(SL slot)；
在图10中，SL slots(M1)位于F symbols(L1)结尾处，具体的，第一信息可以如下：

即，NR下终端设备UU接口的资源分配方式为：在J2上行时隙结束位置之后的时隙J2’，可以配置为用于SL传输的时隙，K1下行符号所在时隙的剩余符号可以配置为用于SL传输的符号L1，与L1相邻的时隙可以配置为用于SL传输的时隙M1。那么，配置为用于SL传输的符号或时隙长度，可以由M1、J2’的长度数值得出。
当然，F symbols的位置及数量也可以由UL symbol的位置及数量决定，用于补足一个完整的时隙，那么在图11中，SL slots(M2)位于F symbols(L2)开始处，具体的，由于符号数量的变化，重新定义如下位置和长度的SL时隙：
Mode 2.4：定义M2(SL slots)，L2(F symbols)，以及J2’(SL slot)位于UL slots的结尾处；
->J1(DL slot，UU)，K1(DL symbol，UU)，…(FFF…)，M2(SL slots)，L2(F symbols)， K3(UL symbol，UU)，J2(UL slot，UU)，J2’(SL slot)；
其中，J1(DL slot，UU)为用于DL传输的slot个数，K1(DL symbol，UU)为用于DL传输的symbol个数，L2(F symbols)为灵活符号个数(表示可以存在于第一信息，也可以不存在，当不存在时，一个周期长度(P1，P1+P2)减去所有的slot以及symbol个数的指示所剩余的就是灵活符号个数)，K3(UL symbol，UU)为用于UL传输的symbol个数，J2(UL slot，UU)为用于UL传输的slot个数，J2’(SL slot)为用于SL传输的slot个数，M2(SL slots)为用于SL传输的slot个数；其中，用于SL传输的M2(SL slots)位于用于UL传输的symbol之前，具体为用于UL传输的symbol与L2(F symbols)之前，用于SL传输的J2’(SL slot)位于用于UL传输的slot之后。
其中，示例性的，定义K2＝9，M2＝2，L2＝8，那么，结合图11，第一信息如下：
->J1(DL slot，UU)，K1(DL symbol，UU)，K2(flexible symbol，UU)，M2(SL slots)，L2(F symbols)，K3(UL symbol，UU)，J2(UL slot，UU)，J2’(SL slot)；
即，NR下终端设备UU接口的资源分配方式为：在J2上行时隙结束位置之后的时隙J2’，可以配置为用于SL传输的时隙，K3上行符号所在时隙的剩余符号可以配置为用于SL传输的符号L2，与L2相邻的时隙可以配置为用于SL传输的时隙M2。那么，配置为用于SL传输的符号或时隙长度，可以由M2、J2’的长度数值得出。
上述Mode 2中，在第一信息中定义L1(F symbols)和L2(F symbols)，用于补充其所在时隙的原本空白的符号空间。比如，由于K1表示DL symbol，即所在时隙部分符号为DL symbol，那么在Mode 2.1中使L1(F symbols)位于K1(DL symbol，UU)之后，以实现将K1所在时隙的剩余符号配置为用于SL传输的灵活符号。
方案2：在一种可能的实现方式中，建立index，用于指示每一可以配置为用于SL传输的时隙和/或符号的位置和长度。即index与配置为用于SL传输的时隙和/或符号的位置和长度之间存在映射关系。在上述RRC信令(SL-TDD-configuration)包含index,从而使得当RRC信令下发给终端设备时，终端设备能够根据index的含义理解其中所包含的SL slot或SL symbol的含义，正确解读该用于指示用于SL传输的时隙或符号的位置和长度的RRC信令。具体的，每一index的含义，或者说该映射关系，可以通过该RRC信令，或别的RRC信令通知给终端设备，或预先设置在终端设备。
示例性的，可以将方案1中的不同的模式(Mode 1、Mode 2)及对应的子模式(Mode1.1、Mode 1.2、Mode 2.1、Mode 2.2、Mode 2.3、Mode 2.4)依次对应不同index，并包含于上述RRC信令或别的RRC信令从而使得终端设备能获知上述参数(如L，M和J2’中任意一者，具体为L1，L2，M1，M2，J2’中任意一者)的含义。
或者，在上述RRC信令中指示方案1中的不同的模式及对应的子模式，并且L1，L2，M1，M2，J2’按照顺序依次指示从而使得终端设备能获知L1，L2，M1，M2，J2’的含义。
