需要说明的是，上述无线通信系统包括但不限于：窄带物联网系统(narrow band-internet of things，NB-IoT)、全球移动通信系统(global system for mobile communications，GSM)、增强型数据速率GSM演进系统(enhanced data rate for GSM evolution，EDGE)、宽带码分多址系统(wideband code division multiple access，WCDMA)、码分多址2000系统(code division multiple access，CDMA2000)、时分同步码分多址系统(time division-synchronization code division multiple access，TD-SCDMA)，长期演进系统(long term evolution，LTE)以及增强移动宽带(enhanced mobile broad band，eMBB)，URLLC和基于LTE演进的物联网技术(LTE enhanced MTO，eMTC)。
图4是适用于本申请实施例的通信系统的另一个示意图。如图4所示，为本申请实施例用于无线投屏场景时的通信系统400，包括电视和手机，电视和手机之间进行信息的交互。此外，本申请实施例还可以应用于虚拟现实(virtual reality，VR)游戏、手机应用 程序(application，APP)中的数据编码、解码等多种应用场景。应理解，在上述应用场景中，电视以及手机等可以用于执行本申请实施例中网络设备的相应功能，或者也可以用于执行本申请实施例中终端设备的相应功能，本申请实施例对此不作限定。
本申请实施例还可以应用于URLLC中。URLLC在自动驾驶、工业制造、车联网以及智能电网等领域应用广泛，以工业制造领域为例，工厂中的终端具体是一些用于进行生产制造的设备，可以通过无线网络实现对终端的控制，由于在工厂中的生产制造作业对精度有着较高的要求，因此对通信延迟以及稳定性也提出了要求。
请参阅图5，在工业车间中，终端可能需要进行周期性的运动。例如，终端1在车间中做周期性的椭圆运动，终端2在车间中做周期性的往复运动。终端在运动的过程与基站的相对位置发生改变，因此能够获得最佳通信质量的波束也会随之发生改变。
基于上述通信系统，本申请提供了一种通信的方法。下面对本申请所使用的一些名词或术语进行解释说明，该名词或术语及其相关解释说明内容也作为发明内容的一部分。
一、物理下行控制信道(physical downlink control channel，PDCCH)和物理接收链路控制信道(physical reception link control channel，PRXCH)；
PDCCH主要用于承载下行控制信息(downlink control information，DCI)，承载数据传输相关的控制信息，如数据传输的资源分配信息、时隙内的上行资源或者下行资源的格式信息、上行数据信道以及下行数据信道和信号的功率控制信息等。
在LTE中，PDCCH的时域资源位于每个时隙的前1至3个符号，符号长度由物理控制格式指示信道(physical control format indicator channel，PCFICH)指示。在5G NR中，由于系统带宽更大，需要更加灵活的PDCCH资源分配方案，PDCCH占用的时频域资源位置定义为控制信道资源集合(control resource set，CORESET)，CORESET可以由高层信令等方式配置。
控制信道单元(control channel element，CCE)是PDCCH的基本组成单位。一个CCE占用时频域上N个资源粒子组(resource element group，REG)。其中，一个REG对应时域上一个OFDM符号和频域上一个资源块(resource block，RB)，包括12个连续的资源单元(resource element，RE)；一个确定的PDCCH可以由1个、2个、4个、8个、16个CCE构成，其具体取值由DCI载荷的大小(DCI payload size)和所需的编码速率决定。构成PDCCH的CCE数量被称为聚合等级(aggregation level，AL)。基站可以根据信道状态选择合适的聚合等级，信道状态较差时聚合等级较高。
在一种可能的实现中，可以引入一种物理层控制信道—PRxCCH。该PRxCCH的功能类似于LTE和5G中的PDCCH，具体地，用于传输控制信息的信道，该控制信息用于调度数据传输。应理解，一般地，标准协议是从终端设备角度来描述的，因此物理层的下行控制信道可以描述为物理层接收链路控制信道。
二、物理下行共享信道(physical downlink shared channel，PDSCH)和物理接收链路共享信道(physical reception link shared channel，PRxSCH)；
PDSCH是承载下行业务数据的物理层信道。
PDSCH发送流程可以包括加扰、调制、层映射、天线端口映射、虚拟资源块映射、物 理资源块映射等。
在一种可能的实现中可以引入一种物理层数据信道—PRxSCH。该PRxSCH的功能类似于LTE和5G中的PDSCH。具体地，该信道可以用于终端设备接收数据的信道，和/或用于网络设备传输数据的信道。应理解，一般地，标准协议是从终端设备角度来描述的，因此物理层的下行数据信道可以描述为物理层接收数据信道。
三、物理上行控制信道PUCCH和物理发送链路控制信道PTxCCH；
物理上行控制信道(physical uplink control channel，PUCCH)主要用于承载上行控制信息(uplink control information，UCI)。具体地，可以包括终端设备向网络设备申请上行资源配置的信息、答复下行业务数据是否被终端设备正确接收的信息以及终端设备上报的下行信道的信道状态信息(channel state information，CSI)。
在一种可能的实现中，可以引入一种物理层控制信道—物理发送链路控制信道(physical transmission link control channel，PTxCCH)。该PTxCCH的功能似于LTE和5G中的PUCCH。具体地，该信道用于终端设备传输控制信息的信道，和/或用于网络设备接收控制信息的信道。其中控制信息可以包括如下至少一项：混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)、确认/非确认(acknowledge/negative acknowledge，ACK/NACK)信息、信道状态信息以及调度请求等。应理解，一般地，标准协议是从终端设备角度来描述的，因此物理层的上行控制信道可以描述为物理层发送链路控制信道。
四、物理上行共享信道PUSCH和物理发送链路共享信道PTxSCH；
物理上行共享信道(physical uplink shared channel，PUSCH)用于传输上行的业务数据。PUSCH可以由DCI动态调度，也可以由高层参数配置，进行免调度传输，或者还可以在高层参数配置后，由DCI进行半持续调度。
PUSCH的发送流程可以包括加扰、调制、层映射、转换预编码、预编码、资源映射以及符号生成等过程。
在一种可能的实现中，可以引入一种物理层数据信道—物理发送链路共享信道(physical transmission link shared channel，PTxSCH)。该PTxSCH的功能类似于LTE和5G中的PUSCH。具体地，该信道用于终端设备传输数据的信道，和/或用于网络设备接收数据的信道。应理解，一般地，标准协议是从终端设备角度来描述的，因此物理层的上行数据信道可以描述为物理层发送数据信道。
五、下行控制信息DCI；
下行控制信息(downlink control information，DCI)是在PDCCH上传输的，与PDSCH、PUSCH相关的控制信息。终端设备只有正确解码DCI信息，才能正确的处理PDSCH数据或PUSCH数据。
六、终端设备盲检。
由于终端设备事先并不知道接收到的PDCCH携带的是哪种格式的DCI，也不知道该DCI使用哪个候选PDCCH进行传输，所以终端设备必须进行PDCCH盲检以接收对应的DCI。在终端设备成功解码PDCCH之前，终端设备可能会在每一个可能的候选PDCCH上尝试解码，直到终端设备检测成功PDCCH，或者，达到终端设备期望接收的DCI数量或达到终端设备 的盲检次数限制。
或者换句话说，DCI有多种不同的格式，终端设备在接收PDCCH时，无法确定接收到的DCI属于哪一种格式的DCI，进而无法正确处理PDSCH、PUSCH等信道上传输的数据。因此，终端设备必须对DCI的格式进行盲检。由于终端设备一般不知道当前DCI的格式，也不知道自身需要的信息在那个位置，但是终端设备知道自身期待什么格式的信息，而期待的不同格式的信息对应着不同的期望的RNTI和CCE，因此终端设备可以通过对接收到的DCI，使用期望的RNTI和CCE做CRC校验，即可知道接收到的DCI是否是自身需要的，也知道相应的DCI格式、调制方式，从而进一步接触DCI，上述流程即为终端设备盲检过程。
应理解，通常通过在DCI的信息比特中添加循环冗余校验(cyclic redundancy check，CRC)比特来实现终端设备的检错功能，并且在CRC比特中使用不同类型的无线网络标识(radio network temporary identifier，RNTI)进行加扰，从而将RNTI隐式地编码在CRC比特中。还应理解，不同的RNTI能够同时用于标识终端设备和区分DCI的用途。
此外，对于终端设备的盲检过程，由于PDCCH由多个CCE组成，或者说DCI是承载与该多个CCE上的，所以终端设备需要对该多个CCE进行盲检。然而，如果终端设备以CCE为粒度逐个进行盲检，效率较低，因此，协议中规定了搜索空间(search space)。搜索空间可以简单的理解为，终端设备进行PDCCH盲检时，以几个CCE为粒度进行盲检，例如，若搜索空间中定义CCE的聚合等级AL的取值为4或者8，则终端设备盲检时，先按4个CCE为粒度盲检一遍，再按8个CCE为粒度盲检一遍。
具体地，当搜索空间中定义CCE的AL的取值为4或者8时，网络设备在标识PDCCH时，除了使用上述4或8中的AL外，还会使用CCE的位置索引(CCE index)参数，其中，CCE的位置索引是根据该PDCCH的时频域信息以及聚合等级等计算获得。由于终端设备不能确切的知道PDCCH占用的CCE的聚合等级，以及CCE的起始位置索引，但是终端设备在接收PDCCH之前，接收高层信令，该高层信令指示PDCCH的时频域信息等，并且终端设备根据协议或者网络设备的指示等，比如确定了该PDCCH的聚合等级可能为4，也可能为8，因此终端设备盲检时，可以首先，以聚合等级为4，根据PDCCH的时频域信息，计算该PDCCH中CCE的位置索引，其中包括CCE的起始位置索引，在对应的CCE上进行盲检；然后，在未检测到期望的DCI时或在未达到期望检测到的DCI数量时，终端设备可以再以聚合等级为8，根据PDCCH的时频域信息，计算该PDCCH中CCE的起始位置索引，也即CCE的位置索引，在对应的CCE上进行盲检。
下面以第一通信装置为终端，第二通信装置为基站为例，对本申请实施例中的通信方法进行介绍：
请参阅图6，下面对本申请实施例中的通信方法的一个流程进行描述：
601、终端获取映射关系；
由于终端是周期性移动的，并且移动的轨迹也可以被预测，因此可以确定终端在每个位置所对应的能够获得最佳通信质量的波束，以及终端在每个位置所对应的用于接收控制信息的参数，上述控制信息用于调度基站与终端之间的通信信号的传输。在确定出上述波束以及参数之后，可以获取映射关系，该映射关系指示了上述波束以及参数与时间的对应 关系。
另外，终端的运动轨迹可以通过定位信息、感知、人工智能(artificial intelligent，AI)、或神经网络技术等获取。根据终端的运动轨迹，可以确定波束以及参数与时间的对应关系。
该映射关系可以通过基站获取，比如基站向终端发送信令指示该映射关系，或者，该映射关系预存在终端侧，或者，也可以通过其他的方式获取，比如终端根据AI确定该映射关系，具体此处不做限定。
映射关系包括M个参数集合与M个时间段的映射关系，其中，每个参数集合中包括至少一个参数的取值，M为大于或等于2的整数。
其中，时间段可以包括一个或多个时域符号、一个或多个时隙以及一个或多个子帧中的任一种。比如，一个时间段可以是2个子帧，或者2毫秒(ms)等。
M个时间段可以是Q1个无线帧、Q2个子帧、Q3个时域符号或者Q4毫秒。其中,Q1、Q2、Q3、以及Q4为正整数。
请参阅图7a，如图7a所示，终端与基站之间的通信在多个子帧中进行。每个子帧可以对应一个编号，示例性的，如果终端在图7a中最左侧的第一个子帧接收到来自基站的同步信号，可以将该子帧编号为0，则该子帧之后的子帧分别编号为1、2、3、4、5、6、7、8以及9，对子帧的编号也可以是周期性的，也即将编号为9的子帧的下一个子帧编号为0，并按照上述编号规律进行后续子帧的编号。
可选的，上述M个时间段包括第一时间段和第二时间段，参数集合中参数的取值包括第一取值和第二取值，终端获取参数与时间段的对应关系，包括：第一时间段对应第一取值，第二时间段对应第二取值。
可选的，第一取值与第二取值不同。
如下提供用于终端以及基站中的至少一种设备确定时间段的方法。终端以及基站中的至少一种设备可以根据如下至少一种方法确定时间段。
可选的，M个时间段可以根据时间周期以及时间偏移确定，也即M个时间段与时间周期以及时间偏移具有关联关系。其中，时间周期指示M个时间段的总时长，时间偏移指示M个时间段与基准点的偏移量。
可选的，基站可以发送包括时间周期以及时间偏移中至少一种信息的配置信息。终端可以接收网络设备发送的包括时间周期以及时间偏移中至少一种信息的配置信息，终端根据配置信息确定时间周期以及时间偏移中的至少一种情况。
基准点可以是任意编号的一个子帧，下面以基准点为子帧0进行描述：
如果映射关系是终端接收到的，请参阅图7b，如果终端在第一个子帧9处接收到来自基站的映射关系，则基准点为接收到映射关系的该子帧的下一个子帧0。如果时间偏移为2个子帧，在该基准点2个子帧之后的子帧为子帧2，则该子帧2为M个时间段的起始位置，其中，该起始位置表示终端从该子帧开始根据映射关系接收控制信息。若M个时间段的周期为10个子帧，则M个时间段包括上述子帧2至下一个子帧1，也即10个子帧。
可选的，基站可以发送基准点的配置信息。终端根据配置信息确定基准点。
或者，如果映射关系是预存在终端的，请参阅图7c，则基准点为第一个子帧0。如果时间偏移为2个子帧，在该基准点2个子帧之后的子帧为第一个子帧2，则该子帧2为M个时间段的起始位置。若M个时间段的周期为10个子帧，则M个时间段包括上述子帧2至下一个子帧1，也即10个子帧。
在另一种实现方式中，基准点也可以是终端接收到映射关系的子帧。请参阅图7d，如果终端在第一个子帧9处接收到来自基站的映射关系，则基准点为接收到映射关系的该子帧9，如果时间偏移为2个子帧，在该基准点2个子帧之后的子帧为子帧1，则该子帧1为M个时间段的起始位置。
可选的，M个时间段也可以根据时间起始位置以及时间长度确定，也即M个时间段与时间起始位置以及时间长度具有关联关系。其中，时间起始位置指示M个时间段的起始位置，时间长度指示M个时间段的总时长。
可选的，基站可以发送包括时间起始位置以及时间长度中至少一种信息的配置信息。终端可以接收网络设备发送的包括时间起始位置以及时间长度中至少一种信息的配置信息，根据配置信息确定起始位置以及时间长度中的至少一种情况。
时间起始位置可以是任意编号的一个子帧，下面以时间起始位置为子帧2进行描述：
如果映射关系是终端接收到的，请参阅图7e，如果终端在第一个子帧9处接收到来自基站的映射关系，则时间起始位置为接收到映射关系的该子帧的下一个子帧2。也即该子帧2为M个时间段的起始位置。若M个时间段的周期为10个子帧，则M个时间段包括上述子帧2至下一个子帧1，也即10个子帧。
或者，如果映射关系是预存在终端的，请参阅图7f，则时间起始位置为第一个子帧2。该子帧2为M个时间段的起始位置。若M个时间段的周期为10个子帧，则M个时间段包括上述子帧2至下一个子帧1，也即10个子帧。
如下提供用于终端以及基站中的至少一种设备确定映射关系的方法。终端以及基站中的至少一种设备可以根据如下至少一种方法确定映射关系。
可选的，映射关系可以通过时间偏移、时间周期以及变化间隔确定，也即映射关系与时间偏移、时间周期以及变化间隔具有关联关系。其中，变化间隔也可以称为时间间隔，用于表示参数集合的持续时间或者作用时间。时间间隔可以包括一个或多个时域符号、一个或多个时隙以及一个或多个子帧中的任一种。比如，一个时间间隔可以是2个子帧，或者2毫秒(ms)等。
可选的，基站可以发送时间间隔的配置信息。终端根据配置信息确定时间间隔。
可选的，时间间隔可以是协议预定义的，比如2个子帧，1个子帧等。
可选的，终端接收配置信息，配置信息指示时间周期，时间偏移和时间间隔中至少一项。
可选的，网络设备发送配置信息，配置信息指示时间周期，时间偏移和时间间隔中至少一项。
可选的，时间间隔与终端的运动速度具有对应关系。或者，终端根据终端的运动速度确定所述时间间隔。
比如，当终端的运动速度位于区间1，对应的时间间隔为时间间隔T1；当终端的运动速度位于区间2，对应的时间间隔为时间间隔T2；当终端的运动速度位于区间3，对应的时间间隔为时间间隔T3；或者也可以是其他情况，此处不再赘述。
其中，当变化间隔为P个时间单元时，也即时间间隔为P个时间单元时，指示了从M个时间段的第一个时间段起的每P个时间单元，对应一个参数集合。其中，时间单元可以是子帧、时隙、时域符号、1毫秒、1秒以及1微秒中的任一种，或者也可以是其他情况，具体此处不做限定。
在上述图7b所示实施例的基础上，请参阅图7g，示例性的，变化间隔为2个子帧时，子帧2以及子帧3对应参数集合1，这之后，子帧4以及子帧5对应参数集合2，子帧6以及子帧7对应参数集合3，子帧8以及子帧9对应参数集合4，子帧0以及子帧1对应参数集合5。
可以理解的是，在上述图7g的基础上，请参阅图7h，时间段与参数集合的映射关系可以是周期性的，也即M个时间段结束之后，是另M个时间段的开始。在此基础上，由于变化间隔以及时间周期是不变的，因此终端可以根据映射关系的周期规律，确定出各个子帧分别与参数集合的对应关系，从而在获取到映射关系的子帧处，根据映射关系接收第一控制信息。以图7h为例，终端可以根据规律确定接收到映射关系的子帧9对应参数集合4，接下来的子帧0以及子帧1对应参数集合5，从而终端可以在接收到映射关系的子帧9处根据参数集合4接收第一控制信息。
或者，映射关系可以通过时间起始位置、时间长度以及变化间隔确定，也即映射关系也可以与时间起始位置、时间长度以及变化间隔具有关联关系。其中，变化间隔也可以称为时间间隔，用于表示参数集合的持续时间或者作用时间。时间间隔可以包括一个或多个时域符号、一个或多个时隙以及一个或多个子帧中的任一种。比如，一个时间间隔可以是2个子帧，或者2毫秒(ms)等。
可选的，基站可以发送时间间隔的配置信息。终端根据配置信息确定时间间隔。

可选的，终端接收配置信息，配置信息指示时间起始位置，时间长度和时间间隔中至少一项。

其中，当变化间隔为P个时间单元时，也即时间间隔为P个时间单元时，指示了从M个时间段的第一个时间段起的每P个时间单元，对应一个参数集合。其中，时间单元可以是子帧、时隙、时域符号、1毫秒、1秒以及1微秒中的任一种，或者也可以是其他情况，具体此处不做限定。
可选的，时间间隔与终端的运动速度具有对应关系。或者，终端根据终端的运动速度确定所述时间间隔。
比如，当终端的运动速度位于区间1，对应的时间间隔为时间间隔T1；当终端的运动速度位于区间2，对应的时间间隔为时间间隔T2；当终端的运动速度位于区间3，对应的 时间间隔为时间间隔T3；或者也可以是其他情况，此处不再赘述。

可以理解的是，在上述图7i的基础上，请参阅图7j，时间段与参数集合的映射关系可以是周期性的，也即M个时间段结束之后，是另M个时间段的开始。在此基础上，由于时间长度以及变化间隔是不变的，因此终端可以根据映射关系的周期规律，确定出各个子帧分别与参数集合的对应关系，从而在获取到映射关系的子帧处，根据映射关系接收第一控制信息。以图7j为例，终端可以根据规律确定接收到映射关系的子帧9对应参数集合4，接下来的子帧0以及子帧1对应参数集合5，从而终端可以在接收到映射关系的子帧9处根据参数集合4接收第一控制信息。
上面对时间周期为10个子帧，变化间隔为2个子帧，时间偏移为2个子帧的情况进行了描述，为了便于对本方案的进一步理解，下面对时间周期为4个子帧，变化间隔为4个子帧，时间偏移为0个子帧的情况进行描述：
请参阅图7k，示例性的，如果终端在第一个子帧0处接收到映射关系，并且基准点也为子帧0，则M个时间段包括接收到映射关系的子帧0至下一个子帧3，并且子帧0以及子帧1对应参数集合1，子帧2以及子帧3对应参数集合2。
可以理解的是，在实际的实现当中，上述图7a至图7k所示的实施例中，也可以包括更多的子帧，为了描述的简洁，不做过多赘述。
上面对确定M个时间段以及映射关系的方式分别进行了描述，下面对本申请实施例中的参数集合进行描述：
本申请实施例中，参数集合中的参数可以包括控制资源集配置信息、RNTI、参考信号配置信息以及控制信息传输方式中的至少一种。
其中，控制资源集配置信息用于配置控制信道资源集合，也即用于指示控制信息对应的时频位置。
请参阅图8a，不同的控制资源集配置信息可以指示对应不同时频位置的时频资源，例如控制资源集配置信息1指示位于时频位置1的时频资源，控制资源集配置信息2指示位于时频位置2的时频资源，控制资源集配置信息3指示位于时频位置3的时频资源，控制资源集配置信息4指示位于时频位置4的时频资源，控制资源集配置信息5指示位于时频位置5的时频资源。基站可以根据处于某个时频位置上的时频资源进行控制信息的发送，例如可以根据处于时频位置1的时频资源发送控制信息，则终端可以根据控制资源集配置信息1指示的时频位置1，在该时频位置1接收控制信息。
示例性的，在一个控制资源集配置信息所指示的时频位置中，包括多个控制信道单元(control channel element，CCE)，多个CCE可以划分为不同的CCE组，其中不同的CCE组可以分别对应不同的波束或者预编码矩阵。
示例性的，在一个控制资源集配置信息所指示的时频位置中，包括多个REG资源单元 (resource element group，REG)，多个REG可以划分为不同的REG组，其中不同的REG组可以分别对应不同的波束或者预编码矩阵。
示例性的，在信道平坦的情况下，CCE组可以对应带宽上的多个离散的资源块(resource block，RB)，并且对应一个预编码矩阵指示符(precoding matrix indicator，PMI)。如果信道不平坦，则CCE组可以对应连续的RB，对应一个PMI。
其中，RNTI用于标识终端设备。RNTI可以用于终端解析第一控制信息，比如控制信息的CRC比特是通过RNTI进行加扰的。
其中，参考信号配置信息用于配置参考信号。参考信号配置信息可以用于指示参考信号对应的时频位置或序列，或者，参考信号配置信息也可以用于指示参考信号对应的时频位置以及序列。
其中，控制信息传输方式用于指示第一控制信息的传输方式。
需要说明的是，上述参数的取值可以对应一个或多个终端。例如，在同一时间段，不同的终端的参数的取值可以是一样的，或者也可以各自不同，此处不做限定。
其中，控制信息传输方式包括第一控制信息传输方式以及第二控制信息传输方式，也即包括单控制信息传输和组控制信息传输。其中第一控制信息传输方式，也即组控制信息传输用于指示第一控制信息包括多个子控制信息。示例性的，请参阅图8b，第一控制信息包括子控制信息1、子控制信息2、子控制信息3、子控制信息4以及子控制信息5，其中子控制信息1对应终端2，子控制信息2对应终端3，子控制信息3对应终端4，子控制信息4对应终端1，子控制信息5对应终端5，多个子控制信息位于不同位置，以本实施例中的终端为终端1为例，终端1需要获取子控制信息4，也即子控制信息4为目标子控制信息。第二控制信息传输方式，也即单控制信息用于指示第一控制信息对应一个终端。
下面对参数集合中所包含的参数的类型的不同情况进行分别描述：
一、参数集合中的参数包括控制资源集配置信息；
当参数集合中的参数包括控制资源集配置信息时，基站可以为终端发送多个控制资源集配置信息，并指示映射关系，即M个时间段与控制资源集配置信息的对应关系。
示例性的，映射关系为控制资源集配置信息随时间的变化，比如可以配置M个时间段对应的M个控制资源集配置信息。可以将多个控制资源集配置信息的标识按照顺序排列，例如控制资源集配置信息1对应的标识为1，控制资源集配置信息2对应的标识为2，控制资源集配置信息3对应的标识为3，控制资源集配置信息4对应的标识为4，控制资源集配置信息5对应的标识为5，则可以得到1,2,3,4,5的标识字符串，或者也可以是其他顺序，比如2,3,5,4,1等，本申请对此不做限定。该标识字符串指示上述控制资源集配置信息在时间上的顺序，映射关系中会包含该标识字符串，由于时间段也具有前后顺序，因此根据标识字符串可以指示参数集合与时间段之间的映射关系，当然在实际的实现中，标识字符串的排列顺序也可以是其他顺序，具体此处不做限定。
示例性的，在上述图7h所示实施例的基础上，当映射关系中的控制资源集配置信息对应的标识字符串为1,2,3,4,5时，时间段1对应参数集合1，参数集合1中包括控制资源集配置信息1，时间段2对应参数集合2，参数集合2中包括控制资源集配置信息2，时间 段3对应参数集合3，参数集合3中包括控制资源集配置信息3，参数集合3中包括控制资源集配置信息3，时间段4对应参数集合4，参数集合4中包括控制资源集配置信息4，时间段5对应参数集合5，参数集合5中包括控制资源集配置信息5。
可选的，基站可以指示终端，M个时间段与控制资源集配置信息的对应关系。
示例性的，基站为终端发送多个控制资源集配置信息，并指示时间段与控制资源集配置信息的对应关系，比如控制资源集配置信息随时间的变化，时间粒度可以是一个或多个符号，1个或多个时隙，一个或多个子帧等。
比如，时间段与控制资源集配置信息的对应关系为：0,3,2,1等。终端即可确定第一个时间段对应的控制资源集配置信息为控制资源集配置信息0,第二个时间段对应的控制资源集配置信息为控制资源集配置信息3,第三个时间段对应的控制资源集配置信息为控制资源集配置信息2,第四个时间段对应的控制资源集配置信息为控制资源集配置信息1。
进一步的，基站可以向终端配置该终端的调度信息在组(group)控制信息中的块标识(block index)，和/或，终端标识(UE index)。如上的配置可以是针对每个控制资源集配置信息配置的，即控制资源集配置信息与块标识信息和/或终端标识具有对应关系，进而实现配对UE组随时间变化。
需要说明的是，当参数集合中的参数包括控制资源集配置信息时，控制资源集配置信息可以与波束具有对应关系。其中，该波束可以为能够获得最佳通信质量的波束。例如，控制资源集配置信息1对应波束1，控制资源集配置信息2对应波束2，控制资源集配置信息3对应波束3，控制资源集配置信息4对应波束4，控制资源集配置信息5对应波束5。终端在获取与时间段对应的控制资源集配置信息时，也获取到了对应的波束信息，需要说明的是，上述波束1、波束2、波束3、波束4以及波束5可以是波束的标识。
需要说明的是，控制资源集配置信息1、控制资源集配置信息2、控制资源集配置信息3、控制资源集配置信息4以及控制资源集配置信息5可以是相同的，或者也可以是不同的，或者也可以部分相同，部分不同，此处不做限定。
可选的，控制资源集配置信息中可以包括控制资源集标识。控制资源集标识与波束标识之间可以具有对应关系。
比如，控制资源集标识1对应波束1，控制资源集标识2对应波束2，控制资源集标识3对应波束3，控制资源集标识4对应波束4。
可选的，本申请实施例中的波束可以是指发送波束，也可以是指接收波束。在通信中，发送端可以用发送波束发送信号，接收端可以用接收波束接收信号。发送端可以确定发送波束，进而用发送波束传输信号。接收端可以确定接收波束，进而用接收波束接收信号。
可选的，发送波束与接收波束之间具有对应关系。接收端可以根据发送波束确定接收波束。
可选的，终端以及基站中的至少一种设备可以根据映射关系，以及控制资源集配置信息与波束的对应关系，确定M个时间段对应的波束，进而实现波束通信，提高通信性能。
本发明实施例可以实现动态的终端配对，实现更灵活的控制信息的传输，动态调度终端，降低波束切换时延，提高通信性能。
参数集合中的参数包括RNTI；

进一步的，基站可以向终端配置该终端的调度信息在组(group)控制信息中的信息块标识(block index)，和/或，终端标识(UE index)。如上的配置可以是针对每个参考信号配置信息配置的，即参考信号配置信息与块标识信息和/或终端标识具有对应关系，进而实现配对UE组随时间变化。
需要说明的是，当参数集合中的参数包括参考信号配置信息时，参考信号配置信息可以与波束具有对应关系。其中，该波束可以为能够获得最佳通信质量的波束。例如，参考信号配置信息1对应波束1，参考信号配置信息2对应波束2，参考信号配置信息3对应波束3，参考信号配置信息4对应波束4，参考信号配置信息5对应波束5。终端在获取与时间段对应的参考信号配置信息时，也获取到了对应的波束信息，需要说明的是，上述波束1、波束2、波束3、波束4以及波束5可以是波束的标识。
需要说明的是，参考信号配置信息1、参考信号配置信息2、参考信号配置信息3、参考信号配置信息4以及参考信号配置信息5可以是相同的，或者也可以是不同的，或者也可以部分相同，部分不同，此处不做限定。
可选的，参考信号配置信息中可以包括参考信号标识。参考信号标识与波束标识之间可以具有对应关系。
比如，参考信号标识1对应波束1，参考信号标识2对应波束2，参考信号标识3对应波束3，参考信号标识4对应波束4。
其中，参考信号标识可以对应不同的参考信号图案信息，或者，参考信号标识信息可以对应不同的参考信号的时频资源信息，或者，参考信号标识信息可以对应不同的参考信号的序列。
示例性的，图7l所示的参考信号图案信息。其中，带阴影的RE表示参考信号的RE，比如，图7l中的4种图案分别为(a)、(b)、(c)、(d)，该图案用于指示参考信号的时频资源所在的RE。4种图案对应的图案标识可以分别为0、1、2以及3。网络设备指示图案标识，终端设备可以根据图案标识确定第一参考信号的时频资源所在的RE。
可选的，本申请实施例中的波束可以是指发送波束，也可以是指接收波束。在通信中，发送端可以用发送波束发送信号，接收端可以用接收波束接收信号。发送端可以确定发送波束，进而用发送波束传输信号。接收端可以确定接收波束，进而用接收波束接收信号。

可选的，终端以及基站中的至少一种设备可以根据映射关系，以及控制资源集配置信息与波束的对应关系，确定M个时间段对应的波束，进而实现波束通信，提高通信性能。
本发明实施例可以实现动态的终端配对，实现更灵活的控制信息的传输，动态调度终端，降低波束切换时延，提高通信性能。
四、参数集合中的参数包括控制信息传输方式；
当参数集合中的参数包括控制信息传输方式时，基站可以为终端发送控制信息传输方 式的配置信息，并指示映射关系，即M个时间段与控制信息传输方式的对应关系。
示例性的，映射关系为控制信息传输方式随时间的变化，比如可以配置M个时间段对应的M个控制信息传输方式。可以将多个控制信息传输方式的标识按照顺序排列，例如第一控制信息传输方式对应的标识为21，第二控制信息传输方式对应的标识为22，则可以得到21,22,21,22,21的标识字符串，或者也可以是其他顺序，比如22,22,21,22,21等，本申请对此不做限定。该标识字符串指示上述控制信息传输方式在时间上的顺序，映射关系中会包含该标识字符串，由于时间段也具有前后顺序，因此根据标识字符串可以指示参数集合与时间段之间的映射关系，当然在实际的实现中，标识字符串的排列顺序也可以是其他顺序，具体此处不做限定。
示例性的，在上述图7g所示实施例的基础上，当映射关系中的控制信息传输方式对应的标识字符串为21,22,21,22,21时，时间段1对应参数集合1，参数集合1中包括第一控制信息传输方式，时间段2对应参数集合2，参数集合2中包括第二控制信息传输方式，时间段3对应参数集合3，参数集合3中包括第一次控制信息传输方式，时间段4对应参数集合4，参数集合4中包括第二控制信息传输方式，时间段5对应参数集合5，参数集合5中包括第一控制信息传输方式。
可选的，基站可以根据终端的周期性业务特征确定采用单控制信息传输方式还是组控制信息传输方式。比如，当调度的终端数较多时，采用组控制信息传输方式。当调度的终端数较少的时候，采用单控制信息传输方式。
可选的，终端可以根据基站的指示进行单控制信息和/或组控制信息检测。
比如，当终端在第一个符号检测到组控制信息时，则无需检测单控制信息。当终端没有检测到组控制信息，如果配置终端检测单控制信息，则终端可以在第二个符号上检测单控制信息。
其中，基站可以向终端配置时间段和控制信息传输方式的对应关系。
方法1：单控制信息传输方式和组控制信息传输方式对应的时域资源不同。
比如，如果一个控制信道资源集包括2个符号，则第一个符号用于组控制信息传输，第二个符号用于单控制信息传输。
发送2：单控制信息传输方式和组控制信息传输方式对应的RNTI不同。
比如，基站可以在一个控制资源集配置信息中向终端配置单控制信息的RNTI-1和组控制信息的RNTI-2。终端在进行单控制信息检测时采用RNTI-1，进行组控制信息检测时采用RNTI-2。
本发明实施例可以实现基于时间段动态的单控制信息和组控制信息的传输方式切换，降低控制信息开销，根据实际调度情况传输控制信息，提高通信性能。
五、参数集合中包括多种参数；
当参数集合中的参数包括多种类型的参数时，例如参数集合中同时包括控制资源集配置信息、RNTI、参考信号配置信息以及控制信息传输方式。可以在映射关系中配置各种参数对应的标识字符串，例如配置控制资源集配置信息对应的标识字符串1,2,3,4,5；配置RNTI对应的标识字符串6,7,8,9,0；配置参考信号配置信息对应的标识字符串 11,12,13,14,15；配置控制信息传输方式对应的标识字符串21,22,21,22,21。示例性的，在上述图7h所示实施例的基础上，当映射关系中包括上述标识字符串时，参数集合1包括控制资源集配置信息1、RNTI1、参考信号配置信息1、以及控制信息传输方式1，参数集合2包括控制资源集配置信息2、RNTI2、参考信号配置信息2、以及控制信息传输方式2，参数集合3包括控制资源集配置信息3、RNTI3、参考信号配置信息3、以及控制信息传输方式1，参数集合4包括控制资源集配置信息4、RNTI4、参考信号配置信息4、以及控制信息传输方式2，参数集合5包括控制资源集配置信息5、RNTI5、参考信号配置信息5、以及控制信息传输方式1。
当然，上述仅为一个示例，在实际的实现中，也可以有其他的实现方式。
可选的，控制资源集配置信息与RNTI、参考信号配置信息、以及控制信息传输方式中的至少一种具有对应关系。
可选的，终端接收多个控制资源集配置信息，多个控制资源集配置信息的一个控制资源集合配置信息对应一个RNTI，一个参考信号配置信息，一种控制信息传输方式中的至少一项。示例性的，一个控制资源集配置信息中包括一个RNTI、一个参考信号配置信息、以及一种控制信息传输方式中的至少一项。
例如，参数集合1至参数集合5中的控制资源配置信息都为控制资源配置信息1，而参数集合1中包括RNTI1，参数集合2中包括RNTI2，参数集合3中包括RNTI3，参数集合4中包括RNTI4，参数集合5中包括RNTI5。
可选的，终端接收一个控制资源集配置信息，一个控制资源集配置信息对应至少两个RNTI、两个参考信号配置信息、以及至少两种控制信息传输方式中的至少一项。示例性的，一个控制资源集合配置信息中包括至少两个RNTI、至少两个参考信号配置信息、以及至少两种控制信息传输方式中的至少一项。
又或者，参数集合1至参数集合5中的控制资源配置信息都为控制资源配置信息1，而参数集合1中包括参考信号配置信息1，参数集合2中包括参考信号配置信息2，参数集合3中包括参考信号配置信息3，参数集合4中包括参考信号配置信息4，参数集合5中包括参考信号配置信息5。
可选的，在实际的实现中，如果第一控制信息的传输方式为第一控制信息传输方式，控制资源集配置信息可以与目标子控制信息在第一控制信息中的位置存在关联关系，也即可以根据控制资源集配置信息确定出目标子控制信息在第一控制信息中的位置。
可选的，终端确定终端的子控制信息在第一控制信息中的信息块位置，信息块位置与参数集合具有对应关系。
比如，终端可以根据参数集合中的参数的取值确定终端的子控制信息在第一控制信息中的信息块位置。
可选的，在实际的实现中，如果第一控制信息的传输方式为第一控制信息传输方式，RNTI可以与目标子控制信息在第一控制信息中的位置存在关联关系，也即可以根据RNTI确定出目标子控制信息在第一控制信息中的位置。
可选的，在实际的实现中，如果第一控制信息的传输方式为第一控制信息传输方式， 参考信号配置信息可以与目标子控制信息在第一控制信息中的位置存在关联关系，也即可以根据参考信号配置信息确定出目标子控制信息在第一控制信息中的位置。
可选的，控制信息传输方式可以与第一控制信息所处的时频位置具有对应关系，例如，在控制资源集配置信息所指示的时频资源中，包括第一个符号和第二个符号，当第一控制信息的传输方式为第一控制信息传输方式时，第一控制信息处于第一个符号，当第一控制信息的传输方式为第二控制信息传输方式时，第一控制信息处于第二个符号。
可选的，第一控制信息传输方式可以与RNTI具有对应关系，例如，当第一控制信息的传输方式为第一控制信息传输方式时，RNTI的取值是RNTI1；当第一控制信息的传输方式为第二控制信息传输方式时，RNTI的取值是RNTI2。
需要说明的是，上述参数集合1、参数集合2、参数集合3、参数集合4以及参数集合5可以是相同的，或者也可以是不同的，或者可以部分相同，部分不同，此处不做限定。
可选的，RNTI、参考信号配置信息以及控制信息传输方式中的至少一种也可以配置在控制资源集配置信息中。例如，RNTI1和控制资源集配置信息1对应时间段1，则可以将RNTI1配置在控制资源集配置信息1中，也即控制资源集配置信息1与RNTI1具有对应关系。终端在确定到控制集配置信息1与时间段1具有对应关系的同时，也确定了RNTI1与时间段1具有对应关系，从而不需要再设置用于指示RNTI1与时间段1的映射关系的标识字符串。
可以理解的是，终端需要获取各个标识字符与参数的取值的对应关系，例如，当终端获取到控制资源集配置信息的标识字符“1”时，终端可以确定该标识字符“1”对应控制资源集配置信息1。例如，当终端获取到RNTI的标识字符“6”时，终端可以确定该标识字符“6”对应RNTI6。例如，当终端获取到参考信号配置信息的标识字符“11”时，终端可以确定该标识字符“11”对应参考信号配置信息11。标识字符与参数的取值的对应关系可以是预先配置在终端中，或者也可以是与映射关系一起被终端获取。
602、终端在第一时间段根据映射关系接收第一控制信息；
在获取了映射关系之后，终端在第一时间段根据映射关系接收来自基站的第一控制信息，该第一控制信息用于调度通信信号的传输。示例性的，在图7h所示实施例的基础上，请参阅图8c，终端在如图8c所示子帧2处根据映射关系接收第一控制信息，上述子帧2即为第一时间段。
由映射关系可知，在上述子帧2对应的参数集合为参数集合1，示例性的，参数集合1中包括控制资源集配置信息1、RNTI1、参考信号配置信息1以及控制信息传输方式1。终端可以根据参考信号配置信息1确定参考信号对应的时频位置和/或序列，从而进行信道估计。
可选的，网络设备和/或终端可以确定控制信息的联合信道估计的资源粒度，所述资源粒度可以是CCE的数量，或者，REG的数量。比如，信道估计的资源粒度可以是N1个CCE或者N2个资源块组(resource element，REG)，其中，N1和N2为大于0的整数。
可选的，终端接收指示信息，所述指示信息用于指示信道估计的资源粒度。对应的，网络设备可以发送指示信息。
终端根据控制资源集配置信息1确定第一控制信息的对应的时频位置，并根据RNTI1对第一控制信息进行盲检，从而获取第一控制信息。
当第一控制信息的传输方式为第一控制信息传输方式时，终端需要获取目标子控制信息在第一控制信息中所处的位置，该目标子控制信息为对应该终端的子控制信息。基站可以向终端发送该目标子控制信息对应的标识，终端根据该标识获取目标子控制信息。或者，基站也可以向终端发送第一控制信息所需要调度的各个终端的标识，以及需要调度的各个终端分别与子控制信息的位置的对应关系，从而使得各个终端确定各自对应的子控制信息的位置。
又或者，如果控制资源集配置信息1、参考信息配置信息1以及RNTI1中的至少一种与目标子控制信息在第一控制信息中的位置存在对应关系，终端也可以根据该对应关系确定目标子控制信息在第一控制信息中的位置。
又或者，终端可以根据参数集合中的至少一个参数的取值确定目标子控制信息的位置，也即参数集合中的至少一个参数的取值与目标子控制信息的位置具有关联关系。示例性的，以参数集合1中的RNTI1为例，RNTI1可以与目标子控制信息的位置具有关联关系，也即终端获取了RNTI1之后可以确定出目标子控制信息的位置。
可选的，第一控制信息传输方式以及第二控制信息传输方式所对应的控制信息的时频位置是不同的。例如，当采用第一控制信息传输方式时，第一控制信息可以位于控制资源集配置信息1所指示的时频位置中的第一个时域符号中。当采用第二控制信息传输方式时，第一控制信息可以位于控制资源集配置信息1所指示的时频位置中的第二个时域符号中。
可选的，控制信息传输方式也可以与RNTI的取值具有关联关系，示例性的，当采用控制信息传输方式1时，对应的，可以采用RNTI1对第一控制信息进行盲检。当采用控制信息传输方式2时，对应的，可以采用RNTI2对第一控制信息进行盲检。
可选的，参数集合也可以与能够获得最佳通信质量的波束具有对应关系，终端在确定参数集合中参数的取值之后，可以根据对应关系确定出相应的波束，从而直接根据该波束进行通信，无需进行波束跟踪以及波束扫描等步骤，降低了终端的通信时延。示例性的，终端根据参数集合1中的控制资源集配置信息1、RNTI1、参考信号配置信息1以及控制信息传输方式1确定出相应的波束1，从而可以在子帧2以及子帧3根据该波束1进行通信。
需要说明的是，不同DCI的用途可以是不同的，例如，包括用于上行或者下行时进行传输资源分配的DCI、用于对上行功率控制进行调整的DCI、针对下行双流空分复用的DCI等等。针对不同用途的DCI，可以使用不同的DCI格式进行区分。在实际的实现中，用于调度信号传输的信息可以分成三种，控制信息中可以包括三种中的至少一种。第一种信息为用于进行信道估计的信息，例如用于指示时频资源位置的信息、以及指示解调参考信号的序列的信息等。
第二种信息为用于解码物理下行共享信道(physical downlink shared channel，PDSCH)的信息，比如调制与编码策略(modulation and coding scheme，MCS)、HARQ进程号(HARQ process number)以及新数据指示符(new data indicator，NDI)等。
第三种信息为用于发送上行控制信息(Uplink Control Information，UCI)信息，比 如PUCCH资源、发射功率控制(transmit power control，TPC)、码块组传输信息(code block group transmission information，CBG)配置、信道状态信息(channel state information，CSI)触发信息以及探测参考信号(sounding reference signal，SRS)触发信息等。
为了降低终端盲检的复杂度，可以将上述第一种信息作为第一类型控制信息进行传输，第二种信息可以作为第二类型控制信息传输，第三种信息可以作为第三类型控制信息传输；或者，第一种信息和第二种信息作为第一类型控制信息传输，第三种信息作为第二类型控制信息传输；或者，第一种信息作为第一类型控制信息传输，第二种信息和第三种信息作为第二类型控制信息传输。通过将DCI中包括的信息分部分传输，使得终端设备可以并行处理不同种类的信息，从而降低通信时延。
请参阅图9，如图9所示，以第一类型信息作为第一DCI，第二类型信息作为第二DCI，第三类型信息作为第三DCI。此时终端设备可以实现：信道估计与盲检第二DCI的并行处理，和/或，译码PDSCH与确定第三DCI的并行处理，和/或，译码PDSCH与准备PUCCH、CSI处理以及SRS处理的并行处理。即在对第一类型控制信息进行盲检之后，可以确定物理下行共享信道的解调参考信号，进行信道估计。这时，盲检第二类型控制信息可以与信道估计同步进行。之后，对PDSCH进行译码，这时，译码PDSCH与确定第三类型控制信息可以同步进行，或者译码PDSCH也可以与确定第三类型控制信息、准备PUCCH、CSI处理以及SRS处理同步处理，最后发送UCI，从而降低通信时延。
上述第一控制信息可以是第一类型控制信息、第二类控制信息以及第三类型控制信息中的至少一种。
603、终端在第二时间段根据映射关系接收第二控制信息。
终端在第二时间段根据映射关系接收第二控制信息，第二时间段可以是上述子帧2之后的子帧，例如可以是上述子帧2的下一个子帧4，则终端在该子帧4根据映射关系，确定出需要根据参数集合2接收第二控制信息。
可以理解的是，并非在所有时间段中都需要根据参数集合中的取值接收控制信息，示例性的，请参阅图8c，在第一时间段，也即子帧2中如果根据参数集合1接收了第一控制信息，由于下一个子帧，也即子帧3也对应参数集合1，因此在子帧3可以不再接收控制信息，而是执行业务。
需要说明的是，步骤603为可选步骤，在实际的实现中，也可以不执行。
本申请实施例中，终端可以根据映射关系确定在各个时间段对应的参数集合，并在时间段根据对应的参数集合接收控制信息，并且由于参数集合与波束具有对应关系，终端可以根据参数集合确定能够获取最佳通信质量的波束，进一步降低了通信时延。
