Description

时域资源分配方法及相关产品
本申请要求于2020年06月28日提交中国专利局、申请号为202010602225.X、申请名称为“时域资源分配方法及相关产品”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
本发明涉及通信技术领域，具体涉及一种时域资源分配方法及相关产品。
背景技术
第五代移动通信系统采用由3GPP开发的新无线(New Radio，NR)标准，5G NR定义了两个频率范围，FR1和FR2，FR1包括6GHz以下的频段，FR2包括20～60GHz内的毫米波频段。5G NR定义了两种传输制式，即时分双工(Time Division Duplex，TDD)和频分双工(Frequency Division Duplexing，FDD)。在NR TDD系统进行时分调度的过程中，调度的最小单位为一个时隙(slot)，每个时隙由若干个正交频分复用(Orthogonal Frequency Division Multiplexin，OFDM)符号组成。其中，slot类型主要分为下行链路(DownLink,DL)时隙、上行链路(UpLink,UL)时隙和混合(mixing)时隙，混合时隙又称为特殊(Special)时隙，即S时隙，其中，DL时隙仅包括DL符号，UL时隙仅包括UL符号，而S时隙由DL符号、gap符号和UL符号组成。
为了系统的通用性，受协议和资源等约束，尽量在UL时隙或S时隙中为每个含有物理下行共享信道(Physical Downlink Share Channel，PDSCH)符号的时隙(即每个DL时隙和S时隙)分配用于信息反馈的UL符号，以便对每个DL时隙和S时隙的下行传输过程进行反馈。比如，在UL时隙中为每个DL时隙和S时隙分配一个物理上行控制信道(Physical Uplink Control Channel，PUCCH)符号，从而对该DL时隙和S时隙的下行传输进行混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈；再如，还可以在UL时隙中分配探测参考信号(Sounding Reference Signal，SRS)符号，从而便于终端设备发送SRS。
然而，这种分配UL符号的方式，一般与DL时隙或S时隙相关，分配方式相对比较固定，可能导致分配的UL符号过剩或者不足，降低了上下行传输效率。
发明内容
本申请提供了一种时域资源分配方法及相关产品。通过切换时域资源分配方式，实现针对性的为终端设备分配时域资源，进而提高上下行传输效率。
第一方面，本申请实施例提供一种时域资源分配方法，该方法的执行主体可以是网络设备，也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。该方法包括：
获取当前时刻的第一时域资源分配方式；
在满足从所述第一时域资源分配方式切换到第二时域资源分配方式对应的预设切换条件的情况下，从所述第一时域资源分配方式切换到所述第二时域资源分配方式；
通过所述第二时域资源分配方式为终端设备分配时域资源。
其中，通过第二时域资源分配方式与第一时域资源分配方式为终端设备分配的时域资源(PUCCH资源)的数量不同，且第二时域资源分配方式与第一时域资源分配方式中的一个时域资源分配方式可以为终端设备分配相对较多的时域资源，而另外一个时域资源分配方式可以为终端设备分配相对较少的时域资源。
可以看出，在本申请实施例中，网络设备可以采用不同的时域资源分配方式为终端设备分配PUCCH资源；即在终端设备对PUCCH资源需求相对较多的情况下，采用一个时域资源分配方式分配资源，以满足终端设备的需求；在终端设备对PUCCH资源需求较少的情况下，可以采用另外一个时域资源分配方式为终端设备分配时域资源。因此，网络设备可以根据终端设备的不同需求，针对性的进行时域资源分配，使时域资源的分配比较灵活，不会出现PUCCH资源过剩或者不足的情况，提高了上行吞吐率和下行吞吐率，以及提高了上下行数据传输效率。
在一些可能的实施方式中，所述时域资源包括物理上行控制信道资源和/或探测参考信号资源。
可以看出，在本实施方式中，通过动态的切换时域资源分配方式，使时域资源的分配比较灵活，并且可以为终端设备分配与需求相对应的上行控制信道资源和/或探测参考信号资源，从而不会产生上行控制信道资源和/或探测参考信号资源过剩或者不足的情况，尽可能的为终端设备保留更多的上下行资源，提高上下行通行效率。
在一些可能的实施方式中，所述第一时域资源分配方式为第一分配方式或第二分配方式；
所述第二时域资源分配方式为所述第一分配方式或所述第二分配方式；
所述第一时域资源分配方式与所述第二时域资源分配方式为不同的时域资源分配方式；
其中，所述第二分配方式分配的上行控制信道资源多于所述第一分配方式。
在一些可能的实施方式中，所述第一分配方式包括在混合时隙中分配一个或多个第一符号、以及一个或多个第二符号，其中，每个第一符号用于混合自动重传请求反馈，每个第二符号用于调度请求、波束管理反馈、探测参考信号或混合自动重传请求反馈；
所述第二分配方式包括在上行时隙中分配多个第三符号，以及在混合时隙中分配第四符号和第五符号，其中，每个第三符号用于混合自动重传请求反馈，且所述第三符号的数量多于所述第一符号的数量，所述第四符号用于调度请求和/或波束管理反馈，所述第五符号用于探测参考信号。
可以看出，在本实施方式中，设置第一分配方式和第二分配方式，且第二分配方式分配的上行控制信道资源多于第一分配方式，则可以在终端设备对上行控制信道资源需求较多的情况下，通过第二分配方式为终端设备分配时域资源，保证每个终端设备都可以分配到相应的上行控制信道资源，从而不会出现下行传输失败的问题，提高了下行吞吐率和下行传输效率；在终端设备对上行控制信道资源需求较少的情况下，通过第一分配方式为终端设备分配时域资源，即分配较少的上行控制信道资源，从而可以在UL时隙中保留更多的上行资源，进而提高上行吞吐率和上行传输效率。
在一些可能的实施方式中，在所述第二时域资源分配方式为所述第一分配方式的情况 下，所述预设切换条件包括以下至少一项：
接入所述网络设备的终端设备的数量小于预设终端数量N 1；
接入所述网络设备的终端设备所使用的波束数量小于预设波束数量M 1；
下行物理资源块利用率小于预设利用率R 1；
下行数据缓存量小于预设缓存量L 1；
上行物理资源块利用率与下行物理资源块利用率的比值大于预设比例K 1；
下行数据缓存量大于预设缓存量L 2的终端设备的数量小于预设终端数量N 2；
在所述第二时域资源分配方式为所述第二分配方式的情况下，所述预设切换条件包括以下至少一项：
接入所述网络设备的终端设备的数量大于预设终端数量N 3；
接入所述网络设备的终端设备所使用的波束数量大于预设波束数量M 2；
下行物理资源块利用率大于预设利用率R 2；
下行数据缓存量大于预设缓存量L 3；
上行物理资源块利用率与下行物理资源块利用率的比值小于预设比例K 2；
下行数据缓存量大于所述预设缓存量L 2的终端设备的数量大于预设终端数量N 4；
其中，N 1≤N 3，M1≤M 2，R 1≤R 2，L 1≤L 3，K 1≤K 2，N 2≤N 4。
可以看出，在本实施方式，设置了多种进行时域资源分配方式的切换条件，这样只要有一个条件满足网络设备都切换到的适配的时域资源分配方式为终端设备分配，从而实现在各种工作场景下，都可以为终端设备分配出匹配的时域资源，也就提高了本申请中时域资源分配方式的应用场景。
在一些可能的实施方式中，所述第二分配方式包括多个第二子分配方式；
所述第一时域资源分配方式为所述第一分配方式或所述多个第二子分配方式中的任意一个第二子分配方式；
所述第二时域资源分配方式为所述第一分配方式或所述多个第二子分配方式中的任意一个第二子分配方式；
其中，所述多个第二子分配方式中任意两个第二子分配方式分配的上行控制信道资源的数量不同，任意一个第二子分配方式分配的上行控制信道资源的数量多于所述第一分配方式；
在所述第二时域资源分配方式中的任意一个第二子分配方式的情况下，所述通过所述第二时域资源分配方式为终端设备分配时域资源，包括：
通过所述第二子分配方式为终端设备分配时域资源。
可以看出，本实施方式中，对第二分配方式进行细粒度的划分，划分成多个第二子分配方式，这样当终端设备对上行控制信道资源需求较多的情况下，可以采用更精准的分配方式为终端设备分配更精精确的时域资源。比如，网络设备确定需要在一个UL时隙中分配三个HARQ资源，则可以采用与该种分配方式对应的第二子分配方式为终端设备分配时域资源，这样就使分配出的时域资源与终端设备的需求更加匹配，可以在满足终端设备对时域资源需求的情况下，尽可能的提高上下行通信效率。

在上行时隙中分配与所述第二子分配方式对应的多个第六符号，以及在混合时隙中分配与所述第二子分配方式对应的第七符号和第八符号；

第五代移动通信系统采用由3GPP开发的新无线(New Radio，NR)标准，5G NR定义了两个频率范围，FR1和FR2，FR1包括6GHz以下的频段，FR2包括20～60GHz内的毫米波频段。5G NR定义了两种传输制式，即TDD和FDD。在TDD传输制式下，网络设备进行时分调度的过程中，调度的最小单位为一个时隙(slot)，每个时隙由若干个正交频分复用(Orthogonal Frequency Division Multiplexin，OFDM)符号组成。其中，slot类型主要分为下行链路(DownLink，DL)时隙、上行链路(UpLink，UL)时隙和混合(Mixing)时隙，混合时隙又称为特殊(Special)时隙，即S slot。其中，DL时隙仅包括DL符号，UL时隙仅包括UL符号，而混合时隙由DL符号、gap符号和UL符号三种符号组成。
网络设备在对终端设备进行时域资源分配的过程中，会将一个无线帧按照预设的时隙配比划分为多个DL时隙、多个S slot以及多个UL时隙。示例性的，在子载波间隔为120KHz的情况下，可以按照上下行时隙配比D:U＝4:1，S slot中的符号配比D:gap:U＝10:2:2，对无线帧进行划分，其中，S slot中的符号配比D:gap:U＝10:2:2是指每个S slot中包括10个DL符号、2个gap符号和2个UL符号。如图1所示，按照时隙配比D:U＝4:1以及D:gap:U＝10:2:2的划分方式，可以将一个无线帧划分为16个时隙配比，其中，一个时隙配比包括4个DL时隙、1个混合时隙和1个UL时隙，图1仅示出了部分时隙配比，图1中的D、S、U分别代表DL时隙、混合时隙以及UL时隙，后续附图中所涉及到的D、S、U均代表DL时隙、混合时隙以及UL时 隙，不再叙述。
为了系统的通用性，受协议和资源等约束，尽量在每个时隙配比中的UL时隙中为每个含有PDSCH符号的时隙(即该时隙配比中的DL时隙)分配一个用于信息反馈的UL符号，以便对每个DL时隙的下行传输过程进行反馈。如图2所示(图2示出了一个时隙配比的情况)，在UL时隙中分别为每个DL时隙以及每个混合时隙分配一个对应的PUCCH符号，即PUCCH资源(如图2所示的PUCCH符号1、PUCCH符号2、PUCCH符号3和PUCCH符号4)。每个PUCCH资源用于终端设备通过PUCCH对下行传输过程进行HARQ反馈；再如，还可以在UL时隙中分配探测参考信号(Sounding Reference Signal，SRS)符号，即SRS资源，该SRS资源用于终端设备向网络设备发送SRS，以便网络设备估计上行信道质量。
可以看出，在一个时隙配比的UL时隙中分配的PUCCH资源的数量与DL时隙的数量相关，则一般需要在UL时隙中预留4个PUCCH资源(4个UL符号)以便进行信息反馈，这种分配时域资源(PUCCH资源)的方式相对比较固定。此外，上下行数据只能在物理上行共享信道(Physical Uplink Share Channel，PUSCH)，也就是说，预留的4个PUCCH资源无法进行数据传输，在实际应用中，在当前接入到网络设备的终端设备的数量较少的情况下，会存在PUCCH资源剩余，由于这部分剩余的PUCCH资源占用了UL时隙中的上行资源，且不能用于上行数据传输，导致上行吞吐率受限，降低了上行数据传输效率；在当前接入到网络设备的终端设备的数量较多的情况下，需要的PUCCH资源比较多，也就可能导致网络设备无法为某个终端设备分配出相应的PUCCH资源，也就无法和该终端设备进行下行数据传输，导致该终端设备的下行传输失败，影响下行吞吐率，降低了下行数据传输效率。
因此，现有的时域资源分配方式，会影响上下行吞吐率，降低了上下行数据传输效率。
首先需要说明的是，本申请中以子载波间隔为120KHz，即一个无线帧为10ms为例，并且以上下行时隙配比D:U＝4:1，S slot中的符号配比D:gap:U＝10:2:2为例说明时域资源分配过程，其他的子载波间隔或者其他的时隙配比对应的时域资源分配方式，与本申请举例说明的时域资源分配方式类似，不再叙述。此外，在说明时域资源分配的过程中，以一个无线帧中的一个时隙配比为例进行具体说明，该无线帧中的其他时隙配比可参照该时隙配比，不再叙述。
参阅图3，图3为本申请实施例提供的一种时域资源分配系统的网络架构图。时域资源分配系统包括网络设备100和终端设备200；
其中，网络设备100获取当前时刻的第一时域资源分配方式；在满足从第一时域资源分配方式切换到第二时域资源分配方式对应的预设切换条件的情况下，网络设备100从第一时域资源分配方式切换到第二资源分配方式，并通过第二时域资源分配方式为终端设备200分配时域资源；网络设备100通过分配好的时域资源与终端设备200进行上行通信或下行通信。
其中，通过第二时域资源分配方式与第一时域资源分配方式为终端设备分配的时域资源(PUCCH资源)的数量不同，且第二时域资源分配方式与第一时域资源分配方式中的一个时域资源分配方式可以为终端设备分配相对较多的时域资源，而另外一个时域资源分配方式可以为终端设备分配相对较少的时域资源。
可以看出，在本申请实施例中，网络设备可以采用不同的时域资源分配方式为终端设 备分配PUCCH资源；即在终端设备对PUCCH资源需求相对较多的情况下，采用一个时域资源分配方式分配资源，以满足终端设备的需求；在终端设备对PUCCH资源需求较少的情况下，可以采用另外一个时域资源分配方式为终端设备分配时域资源。因此，网络设备可以根据终端设备的不同需求，针对性的进行时域资源分配，使时域资源的分配比较灵活，不会出现PUCCH资源过剩或者不足的情况，提高了上行吞吐率和下行吞吐率，以及提高了上下行数据传输效率。
参阅图4，图4为本申请实施例提供的一种时域资源分配方法的流程示意图。该方法应用于网络设备。本申请实施例的方法包括以下步骤：
401：网络设备获取当前时刻的第一时域资源分配方式。
其中，该当前时刻为定时器定时结束的时刻，该定时器用于触发是否进行时域资源分配方式的切换。即在到该定时器定时结束的时刻，网络设备会获取当前时刻的第一时域资源分配方式，并根据该第一时域资源分配方式判断是否需要进行时域资源分配方式的切换。该定时器的定时周期可以为一个无线帧的时长，或者其他值，本申请对此不做限定。
402：在满足从第一时域资源分配方式切换到第二时域资源分配方式对应的预设切换条件的情况下，网络设备从第一时域资源分配方式切换到第二时域资源分配方式，并通过第二时域资源分配方式为终端设备分配时域资源。
其中，该时域资源包括PUCCH资源和/或SRS资源。该PUCCH资源包括以下至少一种：调度请求(Scheduling Request，SR)资源、波束管理(Beam Management，BM)资源和HARQ资源。其中，SRS资源用于终端设备向网络设备发送SRS，以便网络设备进行上行信道质量的估计，SR资源用于终端设备主动向网络设备发起SR，BM资源用于终端设备向网络设备进行BM反馈，HARQ资源用于终端设备向网络设备进行HARQ反馈。
示例性的，该第一时域资源分配方式为第一分配方式或第二分配方式，该第二时域资源分配方式为该第一分配方式或第二分配方式，其中，网络设备通过该第二分配方式为终端设备分配的PUCCH资源多于该第一分配方式。也就是说，该第一分配方式用于对PUCCH资源需求较少的场景，该第二分配方式用于对PUCCH资源需求较多的场景。在本申请中，也就是网络设备通过第二分配方式为终端设备分配的HARQ资源多于该第一分配方式。
此外，该第一时域资源分配方式和第二时域资源分配方式为不同的时域资源分配方式。也就是说，在该第一时域资源分配方式为该第一分配方式的情况下，该第二时域资源分配方式为该第二分配方式；在该第一时域资源分配方式为该第二分配方式的情况下，则该第二时域资源分配方式为该第一分配方式。如图5所示，对时域资源分配方式进行切换，可以是从第一分配方式切换到第二分配方式，也可以是从第二分配方式切换到第一分配方式。
示例性的，该第一分配方式包括在混合时隙中分配一个或多个第一符号以及一个或多个第二符号，其中，每个第一符号用于HARQ反馈，即每个第一符号为一个HARQ资源；每个第二符号用于调度请求、波束管理反馈、探测参考信号或混合自动重传请求反馈，即每个第二符号为SR资源、BM资源、SRS资源或者HARQ资源中的一种。由于，接入网络设备的终端设备的数量较少，则可将原本在UL时隙中预留的PUCCH资源转移到混合时隙中进行预留，则UL时隙中的所有UL符号可以进行上行数据传输，进而提高了上行传输效率和上行吞吐率。如图6所示，由于图6所示的混合时隙中仅有两个UL符号，因此， 可以将一个UL符号，即12个符号分配为HRAQ资源，另一个UL符号，即第13个符号分配为others资源，该others资源为该SR资源、BM资源、SRS资源或者HARQ资源中的一种。
需要说明，本申请并不限定每个混合时隙中的每个UL符号对应的时域资源的具体形式。比如，在实际应用中，可以将第12个符号分配为others资源，将第13个符号分配为HRAQ资源。此外，如果每个混合时隙中UL符号的数量较多，则可采用更多的UL符号为终端设备分配更多的HRAQ资源以及采用更多的UL符号为终端设备分配更多的others资源。本申请并不对混合时隙中HRAQ资源以及others资源的数量和形式进行限定。
下面举例说明网络设备为终端设备分配others资源的方式。
对于一个无线帧来说，会存在16个时隙配比。因此，一个无线帧中可以有16个混合时隙，则可以在不同的混合时隙为终端设备配置不同的others资源。比如，可以错开配置others资源。如图7所示，在一个无线帧中，可以将SR资源、BM资源、SRS资源或者HARQ资源相对错开配置。比如，在第3个时隙，即第一个混合时隙中配置的others资源为SR资源，在第8个时隙，即第二个混合时隙中配置的others资源为BM资源，等等。当然，在实际应用中，可以以各种分配方式配置每个混合时隙对应的others资源，并不对每个混合时隙中的others资源的类型进行限定。比如，可以在第1个混合时隙中配置的others资源为BM资源；此外，也可以在相邻的混合时隙中配置相同的others资源，比如可以将一个无线帧中的混合时隙全部配置为HARQ资源，等等。本申请并不对配置others资源的方式进行限定。
示例性的，第二分配方式包括在上行时隙中分配多个第三符号，以及在混合时隙分配中分配第四符号和第五符号，其中，每个第三符号用于HARQ反馈，每个第三符号为一个HARQ资源，则该第三符号的数量多于第一符号的数量，即该第二分配方式用于为终端设备分配更多的HARQ资源，以便更多的终端设备可以获取到HARQ资源，从而该第二分配方式适用于终端设备较多的场景；其中，该第三符号用于调度请求和/或波束管理反馈，即该第四符号为SR资源或BM资源，该第五符号用于终端设备发送SRS，即该第五符号为SRS资源，
示例性的，如图8所示，可以在UL时隙中分配四个第三符号(即四个HARQ资源)，在混合时隙中分配一个第四符号和第一个第五符号。示例性的，可以将UL时隙中的最后四个UL符号作为该四个第三符号，以便终端设备使用该四个DL符号进行HARQ反馈。当然，在实际应用中可以将UL时隙中其他位置的UL符号作为第三符号，本申请不对第三符号在UL时隙中的位置进行限定。如图8所示，可以将混合时隙中的第12个符号，即混合时隙中的第一个UL符号作为该第四符号，将第13个符号，即第二个UL符号作为该第五符号。
一般来说，在UL时隙中分配四个HARQ资源即可以满足较多终端设备的需求，但是，在实际应用中，如果需要分配更多的HARQ资源，可以在UL时隙中为终端设备分配更多的HARQ资源(第三符号)，以满足终端设备的需求。此外，本申请并不限定每个混合时隙中每个UL符号对应的时域资源的具体形式。比如，在实际应用中，可以将第12个符号作为第五符号，即将12个符号分配为SRS资源，将第13个符号作为第四符号，即将第13 个符号分配为SR资源或BM资源。此外，如果混合时隙中UL符号的数量较多，则可采用更多UL符号为终端设备分配更多的SRS资源、BM资源以及SR资源。本申请不对在混合时隙中分配的SRS资源、BM资源以及SR资源的数量进行限定。
可以看出，当终端设备对PUCCH资源需求较多的情况下，可以切换到第二分配方式，通过第二分配方式为终端设备分配更多的PUCCH资源，以便每个终端设备都可以分配到相应的PUCCH资源，进而不会出现下行传输失败的情况，提高了下行吞吐率以及下行数据传输效率。并且，将SRS资源和BM，SR资源尽可能的配置在混合时隙中，不去占用UL时隙中的UL符号，从而在实现在提高下行吞吐率的同时，保证终端设备可以有较多的上行资源，进而提高上行传输效率。
示例性的，在该第二时域资源分配方式为第一分配方式的情况下，如图5所示，该预设切换条件也称作切换条件2。也就是说，在当前时刻的第一时域资源分配为第二分配方式，且满足该切换条件2的情况下，网络设备会将时域资源分配方式从第二分配方式切换到第一分配方式。其中，该切换条件2包括以下至少一项：
接入该网络设备的终端设备的数量小于预设终端数量N 1；
接入该网络设备的终端设备所使用的波束数量小于预设波束数量M 1；
下行物理资源块利用率小于预设利用率R 1；
下行数据缓存量小于预设缓存量L 1；
上行物理资源块利用率与下行物理资源块利用率的比值大于预设比例K 1；
下行数据缓存量大于预设缓存量L 2的终端设备的数量小于预设终端数量N 2。
示例性的，1在该第二时域资源分配方式为第二分配方式的情况下，如图5所示，则该预设切换条件也称作切换条件1。也就是说，在当前时刻的第一时域资源分配为第一分配方式，且满足该切换条件1的情况下，网络设备会将时域资源分配方式从第一分配方式切换到第二分配方式。其中，该切换条件1包括以下至少一项：
接入该网络设备的终端设备的数量大于预设终端数量N 3；
接入该网络设备的终端设备所使用的波束数量大于预设波束数量M 2；
下行物理资源块利用率大于预设利用率R 2；
下行数据缓存量大于预设缓存量L 3；
上行物理资源块利用率与下行物理资源块利用率的比值小于预设比例K 2；
下行数据缓存量大于该预设缓存量L 2的终端设备的数量大于预设终端数量N 4。
其中，N 1，N 2，N 3，N 4，M1，M 2，R 1，R 2，L 1，L 3，K 1，K 2，且N 1≤N 3，M1≤M 2，R 1≤R 2，L 1≤L 3，K 1≤K 2，N 2≤N 4。
需要说明的是，在小区初始建立情况下，即初始化的时候，为了保证每个终端设备都有PUCCH资源，网络设备会采用第二分配方式为终端设备分配时域资源。
在一些可能的实施方式中，虽然在终端设备的数量较多的情况下，需要分配更多的PUCCH资源，但是，在实际应用中，也可以不用直接分配太多的PUCCH资源。因此，可以将第二分配方式进行更细粒度的划分，即将该第二分配方式划分为多个第二子分配方式，任意两个第二子分配方式之间分配的PUCCH资源的数量不同，并且该多个第二子分配方式之间分配的PUCCH资源的数量依次增多，且任意一个第二子分配方式分配的PUCCH资 源的数量多于该第一分配方式。其中，任意一个第二子分配方式分配的PUCCH资源的数量多于该第一分配方式是指，在本申请中是指在一个时隙配比中，任意一个第二子分配方式分配的HARQ资源的数量多于该第一分配方式。
因此，该第一时域资源分配方式可以为该第一分配方式或该多个第二子分配方式中的任意一个第二子分配方式，该第二时域资源分配方式为可以该第一分配方式或该多个第二子分配方式中的任意一个第二子分配方式。同样，该第一时域资源分配方式和第二时域资源分配方式为不同的时域资源分配方式。
对于任意一个第二子分配方式，其分配时域资源的方式包括：在上行时隙中分配与该第二子分配方式对应的多个第六符号，以及在混合时隙中分配与该第二子分配方式对应的第七符号和第八符号；其中，每个第六符号用于混合自动重传请求反馈，且该第六符号的数量多于该第一符号的数量，但小于或等于该第三符号的数量，该第七符号用于调度请求和/或波束管理反馈，该第八符号用于探测参考信号。
本申请中以该多个第二子分配方式为第二子分配方式A、第二子分配方式B以及第二子分配方式C为例进行详细说明，但不对第二子分配方式的数量和类型进行限定。数量更多的第二子分配方式对应的时域资源分配方式与该三种第二子分配方式类似，不再叙述。其中，第二子分配方式A、第二子分配方式B以及第二子分配方式C分配的PUCCH资源(也就是HARQ资源)的数量依次增多，该第二子分配方式C也就是上述所提到的第二子分配方式，两者在本质上是一致的，不做实质区分。
示例性的，如图9所示，第二子分配方式A对时域资源的分配方式包括：在UL时隙中分配两个HARQ资源，即在UL时隙中的最后两个DL符号为终端设备分配两个HARQ资源；在混合时隙中分配一个SR资源和/或BM资源以及在混合时隙中分配一个SRS资源，即在混合时隙中的最后两个符号为终端设备分配一个SR资源和/或BM资源和SRS资源。同样，图9仅是对第二子分配方式A分配时域资源的一种举例说明，本申请并不对第二子分配方式A分配时域资源的具体方式进行限定。
示例性的，如图10所示，第二子分配方式B对时域资源的分配方式包括：在UL时隙中分配三个HARQ资源，即在UL时隙中的最后三个DL符号为终端设备分配三个HARQ资源；在混合时隙中分配一个SR资源和/或BM资源以及在混合时隙中分配一个SRS资源，即在混合时隙中的最后两个符号为终端设备分配一个SR资源和/或BM资源和SRS资源。同样，图10仅是对第二子分配方式B分配时域资源的一种举例说明，本申请并不对第二子分配方式B分配时域资源的具体方式进行限定。
其中，第二子分配方式C分配时域资源的方式与图8所示的第二分配方式类似，不再叙述。
因此，如图11所示，从第一时域资源分配方式切换到第二时域资源分配方式的具体切换形式以及与该切形式对应的预设切换条件如下所示：
在该第一时域资源分配方式为第一分配方式的情况下，网络设备可以从第一分配方式切换到第二子分配方式A或者第二子分配方式B或者第二子分配方式C，并将从第一分配方式切换到第二子分配方式A对应的预设切换条件称作切换条件1A，将从第一分配方式切换到第二子分配方式B对应的预设切换条件称作切换条件1B，将从第一分配方式切换到第 二子分配方式C对应的预设切换条件称作切换条件1C；
在该第一时域资源分配方式为第二子分配方式A的情况下，网络设备可以从第二子分配方式A切换到第一分配方式或者第二子分配方式B或者第二子分配方式C，并将从第二子分配方式A切换到第一分配方式对应的预设切换条件称作切换条件A1，将从第二子分配方式A切换到第二子分配方式B对应的预设切换条件称作切换条件AB，将从第二子分配方式A切换到第二子分配方式C对应的预设切换条件称作切换条件AC；
在该第一时域资源分配方式为第二子分配方式B的情况下，网络设备可以从第二子分配方式B切换到第一分配方式或者第二子分配方式A或者第二子分配方式C，并将从第二子分配方式B切换到第一分配方式对应的预设切换条件称作切换条件B1，将从第二子分配方式B切换到第二子分配方式A对应的预设切换条件称作切换条件BA，将从第二子分配方式B切换到第二子分配方式C对应的预设切换条件称作切换条件BC；
在该第一时域资源分配方式为第二子分配方式C的情况下，网络设备可以从第二子分配方式C切换到第一分配方式或者第二子分配方式A或者第二子分配方式B，并将从第二子分配方式C切换到第一分配方式对应的预设切换条件称作切换条件C1，将从第二子分配方式C切换到第二子分配方式A对应的预设切换条件称作切换条件CA，将从第二子分配方式C切换到第二子分配方式B对应的预设切换条件称作切换条件CB。
在实际应用中，上述切换条件A1、切换条件B1和切换条件C1可以相同，也可以不同。本申请中以切换条件A1、切换条件B1和切换条件C相同为例进行举例说明，并将切换条件A1、切换条件B1和切换条件C统称为切换条件3。

需要说明的是，在小区初始建立情况下，即初始化的时候，为了保证每个终端设备都有PUCCH资源，网络设备会采用第二子分配方式C为终端设备分配时域资源。
需要说明的是，无论网络设备使用哪种分配方式为终端设备进行时域资源分配，但是在为终端设备分配完时域资源后，可通过指示消息通知该时域资源所在的具体位置，即通知终端设备该时域资源在哪个时隙以及哪个符号。示例性的，对于SR资源和BM资源，网络设备可以在进行无线资源控制(Radio Resource Control，RRC)连接的过程中，通过RRC信令通知终端设备SR资源和BM资源的具体位置；对于SRS资源，网络设备可以通过下行控制信息(Downlink Control Information，DCI)通知终端设备SRS资源的具体位置；对于HARQ资源，网络设备可以通过下行DCI通知终端设备HARQ资源的具体位置。
可以看出，在本申请实施例中，网络设备可以采用不同的时域资源分配方式为终端设备分配PUCCH资源；即在终端设备对PUCCH资源需求相对较多的情况下，采用一个时域资源分配方式分配资源，以满足终端设备的需求；在终端设备对PUCCH资源需求较少的情况下，可以采用另外一个时域资源分配方式为终端设备分配时域资源。因此，网络设备可以根据终端设备的不同需求，针对性的进行时域资源分配，使时域资源的分配比较灵活，不会出现PUCCH资源过剩或者不足的情况，提高了上行吞吐率和下行吞吐率，以及提高了上下行数据传输效率。
可以理解，若网络设备判断当前时刻无需进行时域资源分配方式的切换，则还继续采用当前时刻对应的第一时域资源分配方式为终端设备分配时域资源。
示例性的，从第一时域资源分配方式切换到第二时域资源分配方式，包括从第一分配方式和第二分配方式之间的切换，第一分配方式和各个子分配方式之间的切换，以及各个 第二子分配方式之间的切换，实质上就是将各个资源重配到各个资源对应的符号所在时域位置，该各个资源包括用于SR资源、BM资源、SRS资源以及HARQ资源。以重配HARQ资源为例进行说明，若第一时域资源分配方式为第一分配方式，第二时域资源分配方式为第二分配方式，则第一分配方式是将HARQ资源分配在混合时隙中，比如，分配在第12个符号；然而，第二分配方式将HARQ资源分配在UL时隙中的最后四个UL符号。因此，从第一分配方式切换到第二分配方式，就是将HARQ资源重新配置到最后四个UL符号所对应的时域位置。另外，由于无论是第一分配方式，还是第二分配方式或者任意一个第二子分配方式，都是将SRS资源分配在混合时隙中。因此，可以不用重配置SRS资源，限制SRS资源对应的时域位置，即将SRS资源限制在第二时域资源分配方式对应的时域位置即可。然后，通过指示消息指示完成时域资源分配方式切换后，该SRS资源所在的时域位置，即可满足网络需求。
网络设备为终端设备分配好相应的时域资源后，可使用分配后的时域资源与终端设备进行上行数据传输和下行数据传输。
