Description

下行控制信息处理方法、装置、终端设备及通信系统 技术领域
本申请实施例涉及通信领域，尤其涉及一种下行控制信息处理方法、装置、终端设备及通信系统。
背景技术
在移动通信网络中，网络设备在向终端设备传输实际物理数据之前，需要首先向终端设备发送下行控制信息，用来向用户指示所调度的资源，终端设备进而在该调度的资源上接收网络设备发送的实际物理数据。
在5G通信网络中，下行控制信息的发送具有灵活性的特点。例如，网络设备每个时隙上发送的下行控制信息的数量是灵活的，或者，网络设备发送下行控制信息与实际物理数据的时间间隔是灵活的。
因此，当网络设备以灵活的方式向终端设备发送下行控制信息时，终端设备如何对下行控制信息进行高效的存储和管理，是亟待解决的问题。
发明内容
本申请实施例第一方面提供一种下行控制信息处理方法，该方法包括：
终端设备接收至少一个控制信息，该控制信息用于指示传输下行数据的资源信息，终端设备在接收到控制信息后，将每个控制信息保存在第一存储区域中与控制信息对应的存储空间中，并根据控制信息所指示的传输下行数据的资源信息，接收下行数据。其中，第一存储区域中包括N个存储空间，每个存储空间用于存储一个控制信息，N为大于0的整数，N由混合自动重传请求HARQ进程数量确定。
在该方法中，终端设备开辟N个存储空间用于存储网络设备发送的下行控制信息，终端设备接收到一个下行控制信息后，即可以将下行控制信息保存至一个存储空间中，通过这种方式，可以满足下行控制信息发送的灵活性的要求。进一步的，终端设备所开辟的存储空间的数量N由HARQ进程数量确定，因此，能够保证终端设备开辟的存储空间的数量的合理性，避免存储空间分配过多造成的空间浪费以及存储空间分配过少造成的下行控制信息无法存储的问题。
在一种可能的设计中，HARQ进程数量为下行最大HARQ进程数量。
在该设计中，终端设备基于协议规定的下行最大HARQ进程数量，选择大于等于该数量的数值作为N并建立N个存储空间，由于网络设备发送下行控制信息时会遵循上述下行最大HARQ进程数量进行发送，因此，通过该方式可以保证终端设备开辟的存储空间的数量的合理性，避免存储空间分配过多造成的空间浪费以及存储空间分配过少造成的下行控制信息无法存储的问题。
在一种可能的设计中，HARQ进程数量由网络设备指示。
在该设计中，终端设备基于网络设备指示的进程数量，选择大于等于该数量的数值作为N并建立N个存储空间，同时，网络设备所指示的进程数量基于协议规定的下行最大HARQ进程数量确定，由于网络设备发送下行控制信息时会按照所指示的进程数量进行发送，因此，通过该方式可以保证终端设备开辟的存储空间的数量的合理性，避免存储空间分配过多造成的空间浪费以及存储空间分配过少造成的下行控制信息无法存储的问题。
在一种可能的设计中，终端设备将每个控制信息保存在第一存储区域内与控制信息对应的存储空间中之后，还可以将与控制信息对应的存储空间的索引记录至索引序列的目标位置。其中，索引序列用于记录至少一个占用存储空间的索引，该占用存储空间为第一存储区域中已保存过控制信息的存储空间，索引序列中所记录的存储空间的索引按照索引对应的控制信息指示的下行数据发送时间从早到晚的顺序排列。
在该可能的设计中，终端终端设备在根据至少一个控制信息指示的传输下行数据的资源信息，接收下行数据时，可以在当前时间达到第一存储空间对应的下行数据发送时间时，在第一存储空间中记录的控制信息所指示的资源上接收下行数据。
其中，第一存储空间为记录在索引序列首位的存储空间的索引所对应的存储空间。
在该设计中，由于索引序列中的索引按照索引对应的下行数据发送时间从早到晚进行排序，因此，终端设备每个处理周期中仅需要对索引序列中的首位上的索引对应的下行控制信息指示的下行数据发送时间进行判断，而无需判断其他位置上的索引，因此，通过该方式可以极大提升终端设备接收下行数据时的处理效率。
在该可能的设计中，终端设备可以在第一时间间隔内接收第一控制信息和第二控制信息，第一控制信息的接收时间早于第二控制信息的接收时间，第一控制信息指示的下行数据发送时间晚于第二控制信息指示的下行数据发送时间。
在该可能的设计中，第一控制信息对应的存储空间的索引在索引序列中的位置在第二控制信息对应的存储空间的索引在索引序列中的位置之前。
在一种可能的设计中，终端终端设备在根据至少一个控制信息指示的传输下行数据的资源信息，接收下行数据时，可以遍历第一存储区域，从第一存储区域中选择第二存储空间，并在第二存储空间中记录的控制信息所指示的资源上接收下行数据。
其中，第二存储空间为存储的控制信息所指示的下行数据的发送时间为当前时间的存储空间。
在该设计中，终端设备仅需要开辟N个存储空间，并在每个处理周期中遍历各存储空间，即可进行下行数据的接收，因此，处理逻辑简单，使得终端设备易于维护。

具体实施方式
在现有的一种可能的设计中，针对网络设备发送的下行控制信息，终端设备仅存储一个当前子帧调度的下行控制信息，并实时用于当前子帧的物理下行共享信道(physical downlink shared channel，PDSCH)传输。
而在一些移动通信网络中，例如5G通信网络中，下行控制信息的发送具有灵活性的特点。该灵活性例如可以体现在以下几方面：
1、每个时隙调度的下行控制信息(downlink control information，DCI)数量可以是灵活的。一个终端设备在每个时间点可能接收到多于1个的DCI。
2、从DCI到实际业务的传输时间可以是灵活的。DCI和PDSCH可以位于同一个时隙内，也可以间隔多个时隙。
3、终端接收到的多个DCI与对应的多个实际业务传输的先后关系可以是灵活的。例如，终端设备先接收到的DCI，对应的数据业务后接收，终端设备后接收到的DCI，对应的数据业务先接收。
对于上述灵活性的特点，显然无法通过现有的保存下行控制信息的方式进行下行控制西信息的存储和管理。
本申请实施例旨在提供一种灵活发送下行控制信息场景下的下行控制信息的高效存储和管理方法。

图2为本申请实施例提供的下行控制信息处理方法的交互流程图，如图2所示，该方法的交互过程包括：
S201、网络设备向终端设备发送至少一个控制信息。
可选的，上述控制信息为下行控制信息，用于指示传输下行数据的资源信息。
可选的，上述下行控制信息可以为DCI。
在一种示例性的场景中，网络设备需要向终端设备发送下行数据，则网络设备首先向终端设备发送DCI，在DCI中携带传输网络设备的下行数据的资源信息。该资源信息例如可以包括时域资源、频域资源以及调制阶数等控制信息。
可选的，上述至少一个控制信息可以为网络设备在一个时间间隔内所发送的至少一个控制信息，例如，网络设备可以在一个时隙向终端设备发送至少一个控制信息。或者，上述至少一个控制信息也可以为网络设备在不同的时间间隔内所发送的至少一个控制信息，例如，网络设备先在一个时隙发送一个控制信息，并在与该时隙间隔一定时隙的时隙发送另一个控制信息。本申请实施例对此不做具体限定。
S202、终端设备将每个控制信息保存在第一存储区域内与控制信息对应的存储空间中。
可选的，上述第一存储区域为终端设备为存储下行控制信息所预留的存储区域。上述第一存储区域被划分为N个存储空间，即上述第一存储区域包括N个存储空间，每个存储空间用于存储一个控制信息。
可选的，上述N个存储空间中每个存储空间的大小可以相同，每个存储空间的大小可以为控制信息可能的最大值。
可选的，上述N为大于0的整数。N由混合自动重传请求(hybrid automatic repeat request，HARQ)进程数量确定。
一种可选方式中，上述HARQ进程数量为下行最大HARQ进程数量。
其中，上述下行最大HARQ进程数量可以为协议规定的下行最大HARQ进程数量。
可选的，在该方式中，N可以大于等于上述下行最大HARQ数量。
在该方式中，基于协议定义的下行最大HARQ数量，终端设备直接选择大于等于该数量的一个值作为N。示例性的，协议定义的下行最大HARQ数量为8，终端设备可以设置 N为10，即在终端设备上开辟10个存储空间，可同时存储10个DCI。
在该方式中，终端设备基于协议规定的下行最大HARQ进程数量，选择大于等于该数量的数值作为N并建立N个存储空间，由于网络设备发送下行控制信息时会遵循上述下行最大HARQ进程数量进行发送，因此，通过该方式可以保证终端设备开辟的存储空间的数量的合理性，避免存储空间分配过多造成的空间浪费以及存储空间分配过少造成的下行控制信息无法存储的问题。
另一种可选方式中，上述HARQ进程数量由网络设备指示。
可选的，在该方式中，N可以大于等于网络设备指示的上述HARQ进程数量，该网络设备指示的HARQ进程数量可以小于等于协议规定的下行最大HARQ进程数量。
在该方式中，网络设备可以向终端设备指示自己可能的最大进程数量，并将该最大进程数量发送给终端设备，终端设备基于网络设备所指示的该最大进程数量，终端设备直接选择大于等于该最大进程数量的一个值作为N。在网络设备侧，网络设备可以协议规定的上述下行最大HARQ进程，确定自己可能的最大进程数量，该最大进程数量可以小于等于协议规定的上述下行最大HARQ进程。示例性的，协议定义的下行最大HARQ数量为8，网络设备可以基于该下行最大HARQ数量8，确定自己可能的最大进程数量为7，进而，网络设备将该可能的最大进程数量7发送给终端设备，终端设备基于该可能的最大进程数量7，设置N为9，即在终端设备上开辟9个存储空间，可同时存储9个DCI。
在该方式中，终端设备基于网络设备指示的进程数量，选择大于等于该数量的数值作为N并建立N个存储空间，同时，网络设备所指示的进程数量基于协议规定的下行最大HARQ进程数量确定，由于网络设备发送下行控制信息时会按照所指示的进程数量进行发送，因此，通过该方式可以保证终端设备开辟的存储空间的数量的合理性，避免存储空间分配过多造成的空间浪费以及存储空间分配过少造成的下行控制信息无法存储的问题。
在一种可选的实施方式中，终端设备在开辟了上述N个存储空间之后，当接收到网络设备发送的一个控制信息后，可以将上述控制信息保存在上述N个存储空间中的第一个空闲存储空间中。
可选的，终端设备在开辟了N个存储空间之后，可以首先为每个存储空间分配一个索引。图3为终端设备为第一存储区域中的N个存储空间分配索引的示例图，如图3所示，终端设备开辟连续的N个存储空间，每个存储空间具有唯一的索引，具体的，第一个存储空间的索引为1，第二个存储空间的索引为2，依次类推，第N个存储空间的索引为N。
可选的，终端设备在开辟了存储空间并为每个存储空间分配了唯一的索引之后，还可以为每个存储空间分配一个状态标记，状态标记用于标识存储空间的状态。在初始状态下，每个存储空间为空闲状态，用于标识该存储空间当前可以存储下行控制信息。当终端设备接收到上述控制信息后，可以从第一个存储空间开始，查找第一个处于空闲状态的存储空间，将控制信息存储在该存储空间中，并将该存储空间的状态标记修改为占用状态。
S203、终端设备根据上述至少一个控制信息指示的传输下行数据的资源信息，接收下行数据。
可选的，针对上述关于诸如5G等移动通信系统中下行控制信息发送具有灵活性的特点，网络设备发送下行控制信息和该下行控制信息所指示的PDSCH之间可能间隔一定的时隙，因此，终端设备可能无法实时基于下行控制信息接收下行数据。本实施例中，终端 设备可以按照预设的处理周期确认是否需要在下行控制信息所指示的资源上接收下行数据。可选的，终端设备可以通过下述两种方式接收下行数据。
第一种方式中，终端设备按照下行控制信息所指示的下行数据的发送时间建立一个索引序列，该索引序列中的每个索引为存储下行控制信息的一个存储空间的索引。在每个处理周期中，终端设备判断当前时间是否达到该索引序列中的第一个索引对应的下行控制信息指示的下行数据发送时间，若是，则在第一个索引对应的下行控制信息指示的资源上接收下行数据。
第二种方式中，在每个处理周期中，终端设备遍历N个存储空间中的非空闲存储空间，若当前时间达到遍历到的某个存储空间中的下行控制信息指示的下行数据发送时间，则在该存储空间中的下行控制信息指示的资源上接收下行数据。
上述两种方式的具体实施过程将在下述实施例中进行详细说明。
本实施例中，终端设备开辟N个存储空间用于存储网络设备发送的下行控制信息，终端设备接收到一个下行控制信息后，即可以将下行控制信息保存至一个存储空间中，通过这种方式，可以满足下行控制信息发送的灵活性的要求。例如，终端设备在每个时间点接收到多于1个的DCI，则终端设备可以分别将这些DCI存储在不同的存储空间，进而再根据这些DCI接收下行数据。又例如，终端设备接收的一个DCI与该DCI所指示的PDSCH之间间隔多个时隙，则由于终端设备首先存储了该DCI，因此可以基于该DCI所指示的发送时间，在与该DCI间隔多个时隙的PDSCH上接收下行数据。又例如，终端设备接收到多个DCI，其中先接收到的DCI，对应的数据业务后接收，后接收到的DCI，对应的数据业务先接收，则由于终端设备分别存储了各DCI，因此，可以分别按照各DCI所指示的发送时间接收下行数据，而不会引起下行数据的接收混乱等问题。进一步的，终端设备所开辟的存储空间的数量N由HARQ进程数量确定，因此，能够保证终端设备开辟的存储空间的数量的合理性，避免存储空间分配过多造成的空间浪费以及存储空间分配过少造成的下行控制信息无法存储的问题。
以下分别对上述步骤S203中所述的两种接收下行数据的方式进行说明。
首先为上述第一种方式的实施过程说明。
可选的，在该方式中，终端设备可以将与上述控制信息对应的存储空间的索引记录至索引序列的目标位置。其中，该索引序列用于记录至少一个占用存储空间的索引，该占用存储空间为第一存储区域中已保存过控制信息的存储空间，即占用存储空间是指被占用的存储空间。另外，索引序列中所记录的存储空间的索引按照索引对应的控制信息指示的下行数据发送时间从早到晚的顺序排列。
在该方式中，终端设备按照下行控制信息所指示的下行数据的发送时间建立一个索引序列，该索引序列中的每个索引为存储下行控制信息的一个存储空间的索引。在每个处理周期中，终端设备判断当前时间是否达到该索引序列中的第一个索引对应的下行控制信息指示的下行数据发送时间，若是，则在第一个索引对应的下行控制信息指示的资源上接收下行数据。
可选的，上述索引序列的长度为N，即等于存储空间的数量。索引序列中的索引按照索引对应的下行数据发送时间从早到晚进行排序。
图4为N个存储空间与索引序列的存储示例图，如图4所示，终端设备已接收到4个 DCI，分别为DCI1、DCI2、DCI13和DCI4，DCI1保存在索引为1的存储空间中，DCI2保存在索引为2的存储空间中，DCI3保存在索引为3的存储空间中，DCI4保存在索引为4的存储空间中.其中，DCI2指示的下行数据发送时间最早，DCI1指示的下行数据发送时间为第二位，DCI4指示的下行数据发送时间为第三位，DCI3指示的下行数据发送时间为第四位，则如图4所示，索引序列中的索引排序为：索引2、索引1、索引4、索引3。
在上述N个存储空间均为空闲存储空间时，即终端设备上未保存任何下行控制信息时，上述索引序列中并不存在任何索引，每当终端设备向存储空间中存储一个下行控制信息，可以相应将存储空间的索引插入上述索引序列中。进而在每个处理周期中基于索引序列中的第一个索引序列进行下行数据接收。
可选的，如果终端设备在存储一个下行控制信息时，上述索引序列中不存储任何索引，则终端设备直接将该索引保存至索引序列的首位。在此之后，每当终端设备向存储空间中存储一个下行控制信息，可以按照下述图5所示的过程将该存储空间的索引插入索引序列中。
图5为本申请实施例提供的下行控制信息处理方法中在索引序列中插入一个索引的流程示意图，如图5所示，终端设备在索引序列中插入一个索引的过程包括：
S501、根据上述控制信息所指示的下行数据的资源信息，确定上述所指示的下行数据的发送时间。
可选的，上述控制信息中可以包括时域资源分配信息，终端设备接收到上述控制信息后，可以根据上述控制信息的接收时间以及上述控制信息中包括的时域资源分配信息，计算出下行数据的发送时间、发送符号位置等。
S502、根据上述所指示的下行数据的发送时间，确定上述控制信息对应的存储空间的索引在索引序列中的目标位置，该索引序列中的一个位置用于存储一个存储空间的索引。
可选的，由于索引序列按照索引对应的下行数据发送时间从早到晚进行排序，因此，一种可选方式中，可以从索引序列的最后一个非空闲位置开始，逐个向前查找存储上述控制信息的控制信息对应的存储空间的索引的位置。需要说明的是，在终端设备上未保存任何下行控制信息时，上述索引序列中并不存在任何索引，即上述索引序列的每个位置均为空闲位置。当某个位置上存入一个存储空间的索引后，该位置为非空闲位置。
图6为从索引序列的最后一个有效索引开始查找控制信息对应的存储空间的索引的位置的流程示意图，如图所示，该过程包括：
S601、将上述索引序列的最后一个非空闲位置上所记录的存储空间的索引作为待比较对象。
S602、判断上述待比较对象对应的发送时间是否大于上述控制信息对应的存储空间对应的发送时间，若是，执行步骤S603。若否，执行S605。
可选的，上述待比较对象对应的发送时间是指该索引对应的存储空间上存储的下行控制信息所指示的下行数据的发送时间。
S603、判断上述待比较对象所在位置是否为上述索引序列中的首位，若是，则执行步骤S606，若否，则执行步骤S604。
S604、将上述待比较对象所在位置之前的一个位置上的存储空间的索引作为新的待比较对象。进而继续执行步骤S602。
如果待比较对象所在位置不是索引序列的首位，并且，待比较对象对应的发送时间大于控制信息对应的存储空间对应的发送时间，则说明控制信息对应的存储空间对应的发送时间早于待比较对象对应的发送时间，因此，可以待比较对象之前的一个位置的索引作为新的待比较对象，将控制信息对应的存储空间对应的发送时间继续与该新的待比较对象进行比较。
S605、将上述待比较对象所在位置的后一位置作为上述目标位置。
如果待比较对象对应的发送时间小于上述控制信息对应的存储空间对应的发送时间，则说明控制信息对应的存储空间对应的发送时间在待比较对象所在位置的后一位置，因此，将待比较对象所在位置的后一位置作为记录控制信息对应的存储空间的索引的目标位置。
S606、将上述索引序列中的首位作为所述目标位置。
如果待比较对象所在位置为上述索引序列中的首位，则说明虽然待比较对象对应的发送时间仍然大于控制信息对应的存储空间对应的发送时间，但是已经查找到了索引序列的首位，因此，可以确定控制信息对应的存储空间的索引应记录在索引序列的首位，即控制信息对应的存储空间存储的下行控制信息所指示的下行数据发送时间最早。
在上述步骤S601-S606的过程中，终端设备从索引序列的最后一个非空闲位置开始向上查找比较，以确定控制信息对应的存储空间的索引的目标位置，由于在具体实施过程中，后接收到的DCI所指示的下行数据发送时间相应靠后的几率较大，因此，从索引序列的最后一个非空闲位置开始查找，能够减少查找比较次数，提升处理效率。
S503、在上述目标位置上记录上述控制信息对应的存储空间的索引。
可选的，当经过上述过程确定出控制信息对应的存储空间的索引在索引序列中的目标位置后，终端设备可以在该目标位置上记录控制信息对应的存储空间的索引。
可选的，如果上述目标位置为一个空闲位置，则终端设备可以直接将控制信息对应的存储空间的索引存储至该空闲位置上。如果上述目标位置为一个非空闲位置，即如果上述目标位置上存在预先记录的存储空间的索引，则终端设备可以从上述索引序列的最后一个非空闲位置开始，将上述最后一个非空闲位置至上述目标位置之间的多个第一原始位置上所记录的存储空间的索引逐个记录至上述第一原始位置的后一位置，进而，再将上述控制信息对应的存储空间的索引记录在上述目标位置。
示例性的，假设索引序列中的非空闲位置为位置1至位置8，其中，控制信息对应的存储空间的索引应记录在位置5，则终端设备可以将位置8上的索引记录至位置9，将位置7上的索引记录至位置8，将位置6上的索引记录至位置7，将位置上的索引记录至位置6，进而，再将控制信息对应的存储空间的索引记录至位置5。
经过上述过程完成下行控制信息的存储以及存储下行控制信息的存储空间的索引的按序存储之后，进一步的，终端设备按照预设的处理周期接收下行数据时，在每个处理周期中，可以按照如下过程接收下行数据。
若当前时间达到第一存储空间对应的下行数据发送时间，则在该第一存储空间中记录的控制信息所指示的资源上接收下行数据。
其中，上述第一存储空间为记录在上述索引序列首位的存储空间的索引所对应的存储空间。
图7为本申请实施例提供的下行控制信息处理方法中接收下行数据的流程图，如图7 所示，每个处理周期中，终端设备接收下行数据的过程包括：
S701、终端设备判断当前时间是否达到第一存储空间对应的发送时间，若是，则执行步骤S702。
S702、在上述第一存储空间中记录的控制信息所指示的资源上接收下行数据。
可选的，由于上述索引序列中的索引按照索引对应的下行数据发送时间从早到晚进行排序，因此，可以将处理周期的时长设置为较小的时长，可选的，该处理周期的时长的粒度可以为时隙，也可以为符号，本申请实施例对此不做具体限定。进而，在每个处理周期中，终端设备仅判断当前时间是否达到该索引序列中的第一个索引对应的下行控制信息指示的下行数据发送时间，即索引序列首位上的索引对应的下行控制信息指示的下行数据发送时间，若是，则在第一个索引对应的下行控制信息指示的资源上接收下行数据。
本实施例中，由于上述索引序列中的索引按照索引对应的下行数据发送时间从早到晚进行排序，因此，终端设备每个处理周期中仅需要对索引序列中的首位上的索引对应的下行控制信息指示的下行数据发送时间进行判断，而无需判断其他位置上的索引，因此，通过该方式可以极大提升终端设备接收下行数据时的处理效率。
进一步的，终端设备经过上述图7所示的方式接收下行数据之后，还可以删除上述第一存储空间中所存储的下行控制信息，以及删除上述索引序列的首位所记录的上述第一存储空间的索引。
可选的，终端设备在删除第一存储空间中所存储的下行控制信息后，还可以将第一存储空间对应的状态标记修改为空闲状态，当终端设备再接收到下行控制信息后，可以将再接收到的下行控制信息保存在该第一存储空间中。
可选的，终端设备删除上述索引序列的首位所记录的上述第一存储空间的索引后，可以将上述索引序列的原第二位置作为上述索引序列的新的首位。
在具体实施过程中，示例性的，上述第一种接收下行数据的方式可以应用于下述的场景中。
首先，终端设备可以在第一时间间隔内接收第一控制信息和第二控制信息，该第一控制信息的接收时间早于第二控制信息的接收时间，该第一控制信息指示的下行数据发送时间晚于该第二控制信息指示的下行数据发送时间。
其中，上述第一时间间隔可以是预设数量的时隙、符号等，本申请实施例对此不做具体限定。
假设第一控制信息是终端设备接收到的第一个控制信息，当终端设备接收到第一控制信息后，首先将第一控制信息保存在第一存储区域的第一个空闲存储空间中，并将该存储空间的索引记录在索引序列的首位。当终端设备再接收到第二控制信息后，将第二控制信息保存在第一存储区域的第二个空闲存储空间中，同时，由于第二控制信息指示的下行数据发送时间早于第一控制信息指示的下行数据发送时间，因此，终端设备按照上述的处理过程，将存储第二控制信息的存储空间的索引记录在索引序列的首位，将存储第一控制信息的存储空间的索引移动至索引序列的第二位。即，第一控制信息对应的存储空间的索引在索引序列中的位置在第二控制信息对应的存储空间的索引在索引序列中的位置之前。
进而，在下一个处理周期中，终端设备判断当前时间是否达到索引序列首位对应的第一控制信息指示的下行数据发送时间，若是，则在对应资源上接收第一控制信息指示的下 行数据，并删除索引序列首位的索引，将第二控制信息对应的索引移动至索引序列首位。依次类推，在此后的下一个处理周期中，再判断当前时间是否达到索引序列首位对应的第二控制信息指示的下行数据发送时间。
以下为上述步骤S203中所述的第二种接收下行数据的方式的说明。
可选的，在上述第二种方式中，在每个上述的处理周期中，终端设备可以遍历上述第一存储区域，从上述第一存储区域中选择第二存储空间。
其中，上述第二存储空间为存储的下行控制信息所指示的下行数据的发送时间为当前时间的存储空间。
可选的，该方式中，终端设备在按照上述步骤S202的方式将下行控制信息保存在第一存储区域的一个存储空间中。在每个上述的处理周期中，终端设备直接遍历第一存储区域，逐个判断第一存储区域中的占用状态的存储空间中的下行控制信息指示的下行数据发送时间是否已经达到，如果遍历到的某个存储空间中的下行控制信息指示的下行数据发送时间已经达到，则在该存储空间的下行控制信息指示的资源上接收下行数据。
在该方式中，终端设备仅需要开辟N个存储空间，并在每个处理周期中遍历各存储空间，即可进行下行数据的接收，因此，处理逻辑简单，使得终端设备易于维护。
