Description

电子设备、无线通信方法和计算机可读存储介质
本申请要求于2021年4月2日提交中国专利局、申请号为202110361347.9、发明名称为“电子设备、无线通信方法和计算机可读存储介质”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
本公开的实施例总体上涉及无线通信领域，具体地涉及电子设备、无线通信方法和计算机可读存储介质。更具体地，本公开涉及一种作为无线通信系统中的网络侧设备的电子设备、一种作为无线通信系统中的用户设备的电子设备、一种由无线通信系统中的网络侧设备执行的无线通信方法、一种由无线通信系统中的用户设备执行的无线通信方法以及一种计算机可读存储介质。
背景技术
DCI(Downlink Control Information，下行控制信息)是由网络侧设备发送给UE的下行控制信息，包括但不限于资源分配、HARQ信息、功率控制等。DCI可以调度PDSCH(Physical Downlink Share Channel，物理下行共享信道)，也可以调度PUSCH(Physical Uplink Shared Channel，物理上行共享信道)。DCI由PDCCH(Physical Downlink Control Channel，物理下行控制信道)承载，UE通过对PDCCH进行盲检来对DCI进行译码，从而获取其中的调度信息。
在DCI调度多个数据信道的情况下，由于该DCI中包括多个数据信道的调度信息，一旦UE不能对该DCI正确译码，那么UE将不能获得多个数据信道的调度信息，因此期望UE能够对该DCI进行正确译码。此外，由于该DCI中的内容较多，UE对PDCCH的盲检难度也会增加。
因此，有必要提出一种技术方案，以提高在DCI调度多个数据信道的情况下UE对该DCI进行正确译码的概率，即提高DCI传输的可靠性。
发明内容
这个部分提供了本公开的一般概要，而不是其全部范围或其全部特征的全面披露。
本公开的目的在于提供一种电子设备、无线通信方法和计算机可读存储介质，以提高在DCI调度多个数据信道的情况下UE对该DCI进行正确译码的概率，即提高DCI传输的可靠性。
根据本公开的一方面，提供了一种电子设备，包括处理电路，被配置为：生成第一下行控制信息DCI，所述第一DCI包括多个数据信道的调度信息；以及使用数据信道承载多个所述第一DCI。
根据本公开的另一方面，提供了一种电子设备，包括处理电路，被配置为：使用数据信道接收多个第一下行控制信息DCI；以及对所述多个第一DCI进行软合并和译码，以确定所述第一DCI中包括的多个数据信道的调度信息。
根据本公开的另一方面，提供了一种由无线通信系统中的电子设备执行的无线通信方法，包括：生成第一下行控制信息DCI，所述第一DCI包括多个数据信道的调度信息；以及使用数据信道承载多个所述第一DCI。
根据本公开的另一方面，提供了一种由无线通信系统中的电子设备执行的无线通信方法，包括：使用数据信道接收多个第一下行控制信息DCI；以及对所述多个第一DCI进行软合并和译码，以确定所述第一DCI中包括的多个数据信道的调度信息。
根据本公开的另一方面，提供了一种计算机可读存储介质，包括可执行计算机指令，所述可执行计算机指令当被计算机执行时使得所述计算机执行根据本公开所述的无线通信方法。
根据本公开的另一方面，提供了一种计算机程序，所述计算机程序当被计算机执行时使得所述计算机执行根据本公开所述的无线通信方法。
使用根据本公开的电子设备、无线通信方法和计算机可读存储介质，用数据信道承载包括多个数据信道的调度信息的DCI。这样一来，不会增加UE对PDCCH进行盲检的难度。进一步，用数据信道承载多个这样的DCI。这样一来，由于多次发送包括相同内容的DCI，UE可以对多个DCI进行软合并，从而提高了对DCI进行正确译码的概率。总之，根据本公开的技术方案，可以提高包括多个数据信道的调度信息的DCI的传输的可靠性。
从在此提供的描述中，进一步的适用性区域将会变得明显。这个概要中的描述和特定例子只是为了示意的目的，而不旨在限制本公开的范围。

<1.问题的描述>
前文中提到，在DCI调度多个数据信道的情况下，由于该DCI中包括多个数据信道的调度信息，一旦UE不能对该DCI正确译码，那么UE将不能获得多个数据信道的调度信息，因此期望UE能够对该DCI进行正确译码。此外，由于该DCI中的内容较多，如果该DCI仍然由PDCCH承载，那么UE对PDCCH的盲检难度也会增加。
因此，有必要提出一种技术方案，以提高在DCI调度多个数据信道的情况下UE对该DCI进行正确译码的概率，即提高DCI传输的可靠性。
本公开针对这样的问题提出了一种无线通信系统中的电子设备、由无线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质，以提高在DCI调度多个数据信道的情况下UE对该DCI进行正确译码的概率，即提高DCI传输的可靠性。
根据本公开的无线通信系统可以是5G NR(New Radio，新无线)通信系统，也可以是6G通信系统。
根据本公开的无线通信系统可以用于高频段通信场景。例如，根据本公开的无线通信系统可以用于52.6GHz到71GHz的高频段。当然，随着技术的发展，根据本公开的无线通信系统也可以用于其他的高频段。在高频段通信场景中，一个DCI可以调度多个数据信道，因此如何保证携带多个数据信道的调度信息的DCI的传输的可靠性更加重要。
根据本公开的网络侧设备可以是基站设备，例如可以是eNB，也可以是gNB(第5代通信系统中的基站)。
根据本公开的用户设备可以是移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
<2.网络侧设备的配置示例>
图2是示出根据本公开的实施例的电子设备100的配置的示例的框图。这里的电子设备100可以作为无线通信系统中的网络侧设备，具体地可以作为无线通信系统中的基站设备。
如图2所示，电子设备100可以包括第一生成单元110、编码单元120和通信单元130。
这里，电子设备100的各个单元都可以包括在处理电路中。需要说明的是，电子设备100既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，第一生成单元110可以生成第一DCI，第一DCI包括多个数据信道的调度信息。也就是说，第一DCI可以调度多个数据信道。
根据本公开的实施例，编码单元120可以对电子设备100生成的各种信息进行编码。例如，编码单元120可以对第一生成单元110生成的第一DCI进行数据信道编码，也就是说，使用数据信道承载第一DCI。
根据本公开的实施例，可以用数据信道承载多个第一DCI。也就是说，用数据信道上的多个时频资源分别承载多个第一DCI。
根据本公开的实施例，电子设备100可以通过通信单元130将多个第一DCI发送出去。这里，电子设备100可以将多个第一DCI发送至UE。
由此可见，根据本公开的实施例的电子设备100，可以用数据信道承载包括多个数据信道的调度信息的DCI。这样一来，不会增加UE对PDCCH进行盲检的难度。进一步，用数据信道承载多个这样的DCI。这样一来，由于多次发送包括相同内容的DCI，UE可以对多个DCI进行软合并，从而提高了对DCI进行正确译码的概率。总之，根据本公开的技术方案，可以提高包括多个数据信道的调度信息的DCI的传输的可靠性。
根据本公开的实施例，承载第一DCI的数据信道可以是PDSCH。
根据本公开的实施例，电子设备100还可以包括第二生成单元140，用于生成第二DCI，第二DCI包括与解码多个第一DCI有关的信息。
根据本公开的实施例，编码单元120可以对第二DCI进行控制信道编码。也就是说，使用控制信道承载第二DCI，这里的控制信道可以是PDCCH。
如上所述，根据本公开的实施例，用PDCCH承载第二DCI，第二DCI中包括与解码多个第一DCI有关的信息，用PDSCH承载第一DCI， 并且第一DCI被发送多次。这样一来，第二DCI可以与现有的PDCCH承载的DCI的大小一致，即与现有的DCI兼容，从而不会增加UE盲检PDCCH的难度。
根据本公开的实施例，第一DCI调度的多个数据信道中的每个数据信道可以为上行数据信道，也可以为下行数据信道。也就是说，第一DCI调度的多个数据信道可以全部为上行数据信道，可以全部为下行数据信道，也可以一部分为上行数据信道，另一部分为下行数据信道。这里的上行数据信道可以为PUSCH，下行数据信道可以为PDSCH。
根据本公开的实施例，第一DCI调度的多个数据信道可以在时域上连续或不连续。这里，如果第一DCI调度的多个数据信道在时域上位于连续的时隙中，可以称该多个数据信道在时域上连续；如果第一DCI调度的多个数据信道在时域上位于不连续的时隙中，可以称该多个数据信道在时域上不连续。
图2是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度连续的多个数据信道的设计的示意图。如图2所示，利用PDCCH承载第二DCI，利用PDSCH承载第一DCI，图2示出了第一DCI被发送两次的情形。进一步，在图2中，第一DCI调度了四个数据信道：数据信道1；数据信道2；数据信道3；和数据信道4。这四个数据信道位于相邻的四个时隙中，即任意两个相邻的数据信道位于相邻的时隙中，因此这四个数据信道连续。当然，第一DCI还可以调度除四个以外的其他数目的数据信道。
图3是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度不连续的多个数据信道的设计的示意图。如图3所示，利用PDCCH承载第二DCI，利用PDSCH承载第一DCI，图3示出了第一DCI被发送两次的情形。进一步，在图3中，第一DCI调度了三个数据信道：数据信道1；数据信道2和数据信道3。数据信道1与数据信道2之间间隔了一个时隙，数据信道2与数据信道3之间间隔了一个时隙。因此，这三个数据信道不连续。当然，第一DCI还可以调度除三个以外的其他数目的数据信道。此外，只要有任意两个相邻的数据信道位于不相邻的时隙中，就可以认定为第一DCI调度的数据信道不连续。
图4是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度连续的多个PDSCH的设计的示意图。在图4中，第一DCI调度了四个数据信道，这四个数据信道均为下行数据信道 PDSCH：PDSCH1；PDSCH2；PDSCH3；和PDSCH4。这四个数据信道在时域上连续。
图5是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度连续的多个PUSCH的设计的示意图。在图5中，第一DCI调度了四个数据信道，这四个数据信道均为上行数据信道PUSCH：PUSCH1；PUSCH2；PUSCH3；和PUSCH4。这四个数据信道在时域上连续。
图6是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度连续的多个PDSCH和PUSCH的设计的示意图。在图6中，第一DCI调度了四个数据信道，这四个数据信道包括两个下行数据信道PDSCH和两个上行数据信道PUSCH：PDSCH1；PDSCH2；PUSCH1；和PUSCH2。这四个数据信道在时域上连续。
图7是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度不连续的多个PDSCH的设计的示意图。在图7中，第一DCI调度了三个数据信道，这三个数据信道均为下行数据信道PDSCH：PDSCH1；PDSCH2；和PDSCH3。这三个数据信道在时域上不连续。
图8是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度不连续的多个PUSCH的设计的示意图。在图8中，第一DCI调度了三个数据信道，这三个数据信道均为上行数据信道PUSCH：PUSCH1；PUSCH2；和PUSCH3。这三个数据信道在时域上不连续。
图9是示出根据本公开的实施例的利用数据信道承载多个第一DCI，其中每个第一DCI调度不连续的多个PDSCH和PUSCH的设计的示意图。在图9中，第一DCI调度了三个数据信道，这三个数据信道包括两个下行数据信道PDSCH和一个上行数据信道PUSCH：PDSCH1；PDSCH2；和PUSCH1。这三个数据信道在时域上不连续。
下面来详细描述第二DCI中的内容。
<第一实施例>
根据本公开的实施例，第二DCI可以包括多个第一DCI中的每个第一DCI的时频位置的指示信息。
这里，第一DCI的时频位置可以包括第一DCI的时域位置和频域位 置。
根据本公开的实施例，第一DCI的频域位置可以包括第一DCI的起始子载波位置和持续子载波长度来指示第一DCI的频域位置。例如，电子设备100指示第一DCI的起始子载波位置为1，持续子载波长度为3，则UE可以确定第一DCI的频域位置为标号为1、2和3的子载波。当然，如果频域资源分配的单位为RB或其他单位，也可以用RB或其他单位的标识来指示频域位置。
第一DCI的时域位置可以包括第一DCI所在的时隙和第一DCI在一个时隙中的时域位置。
根据本公开的实施例，可以用第一DCI所在的时隙与第二DCI所在的时隙之间的差值来指示第一DCI所在的时隙。这样一来，接收到第二DCI的UE可以根据第二DCI所在的时隙以及上述差值来确定第一DCI所在的时隙。例如，第二DCI在时隙2中，电子设备100指示上述差值为2，则UE可以确定第一DCI在时隙4中。
根据本公开的实施例，可以用第一DCI在一个时隙中的起始符号位置和持续符号长度来指示第一DCI在一个时隙中的时域位置。例如，电子设备100指示第一DCI在一个时隙中的起始符号位置为1，持续符号长度为3，则UE可以确定第一DCI在一个时隙中的时域位置为标号为1、2和3的OFDM符号。由此，结合第一DCI所在的时隙，UE可以确定第一DCI的时域位置为时隙4中的标号为1、2和3的OFDM符号。
根据本公开的实施例，第二DCI可以用如上所述的方式包括每个第一DCI的时频位置。也就是说，指示信息包括每个第一DCI的时频位置。也就是说，第二DCI的内容可以如下表所示：
表1
Figure PCTCN2022082910-appb-000001
Figure PCTCN2022082910-appb-000002
其中，N为第一DCI的个数。
如上所述，第二DCI隐含指示了数据信道承载的多个第一DCI的个数，即第一DCI被重复发送的次数。也就是说，第二DCI包括了多少个第一DCI的时频位置，第一DCI就有多少个。
如上所述，在第一实施例中，UE根据第二DCI中的内容可以确定第一DCI的个数以及各个第一DCI的时频位置。由于第二DCI分别指示各个第一DCI的时频位置，因此无论各个第一DCI在时域和频域上如何分布，第二DCI都可以准确地指示各个第一DCI的位置。
<第一实施例的变型>
根据本公开的实施例，也可以通过修改资源分配表的方式来指示多个第一DCI中的每个第一DCI的时频位置。例如，电子设备100可以通过RRC信令配置资源分配表，以使得第二DCI中包括的多个第一DCI中的每个第一DCI的时频位置的指示信息与多个资源位置相对应。这样一来，接收到第二DCI的UE可以查找资源分配表、根据指示信息来确定多个资源的位置作为多个第一DCI的时频位置。
如上所述，在第一实施例的变型中，UE根据第二DCI中的指示信息可以确定第一DCI的个数以及各个第一DCI的时频位置。这样一来，可以使得第二DCI与现有标准中的PDCCH承载的DCI的格式和大小兼容。
<第二实施例>
根据本公开的实施例，第二DCI可以包括多个第一DCI中的一个第一DCI的时频位置。同样地，这一个第一DCI的时频位置可以包括第一个第一DCI的时域位置和频域位置。进一步，这一个第一DCI的时域位置可以包括这一个第一DCI所在的时隙和第一个第一DCI在一个时隙中 的时域位置。
根据本公开的实施例，这一个第一DCI可以是多个第一DCI中的任意一个DCI，例如第一个第一DCI。
也就是说，第二DCI的内容可以如下表所示：
表2
Figure PCTCN2022082910-appb-000003
如图1所示，根据本公开的实施例，电子设备100还可以包括第三生成单元150，用于生成除第一DCI和第二DCI之外的其他控制信息。例如，其他控制信息可以为例如RRC信令的高层信令，或者可以为除第一DCI和第二DCI的第三DCI。
根据本公开的实施例，其他控制信息可以包括多个第一DCI的个数以及除一个第一DCI之外的每个第一DCI的时频位置。也就是说，假定第二DCI包括了第一个第一DCI的时频位置，则其他控制信息的内容可以如下表所示：
表3
Figure PCTCN2022082910-appb-000004
如上所述，在第二实施例中，UE根据第二DCI中的内容和其他控制信息中的内容可以确定第一DCI的个数以及各个第一DCI的时频位置。由于第二DCI中仅包括第一个第一DCI的时频位置，因此可以与现有标准中的PDCCH携带的DCI的格式和大小兼容。
<第二实施例的变型1>
根据本公开的实施例，如果其他控制信息中针对某个第一DCI没有包括频域位置，则UE可以认为该第一DCI的频域位置与第二DCI中包括的那一个第一DCI的频域位置相同。类似地，如果其他控制信息中针对某个第一DCI没有包括起始符号位置和/或持续符号长度，则UE可以认为该第一DCI的起始符号位置和/或持续符号长度与第二DCI中包括的那一个第一DCI的起始符号位置和/或持续符号长度相同。
例如，第二DCI中包括第一个第一DCI的时频位置，而其他控制信息中的第二个第一DCI的时频位置仅包括：第二个第一DCI所在的时隙；第二个第一DCI的起始符号位置；第二个第一DCI的持续符号长度，则UE可以根据上述信息确定第二个第一DCI的时域位置，并且认为第二个第一DCI的频域位置与第一个第一DCI的频域位置相同。
再如，第二DCI中包括第一个第一DCI的时频位置，而其他控制信息中的第二个第一DCI的时频位置仅包括：第二个第一DCI的频域位置；第二个第一DCI所在的时隙，则UE可以根据上述信息确定第二个第一DCI的频域位置，并且认为第二个第一DCI的起始符号位置和持续符号长度与第一个第一DCI的起始符号位置和持续符号长度相同，并结合第二个第一DCI所在的时隙来确定第二个第一DCI的时域位置。
又如，第二DCI中包括第一个第一DCI的时频位置，而其他控制信息中的第二个第一DCI的时频位置仅包括：第二个第一DCI所在的时隙，则UE可以认为第二个第一DCI的频域位置与第一个第一DCI的频域位置相同，并且认为第二个第一DCI的起始符号位置和持续符号长度与第一个第一DCI的起始符号位置和持续符号长度相同，并结合第二个第一DCI所在的时隙来确定第二个第一DCI的时域位置。
如上所述，根据本公开的实施例，在某个或者某些第一DCI的时域位置或者频域位置与第二DCI中包括的那个第一DCI的时域位置或者频域位置相同时，可以省略其他第一DCI的时域位置或者频域位置参数，从而节约开销。
<第二实施例的变型2>
根据本公开的实施例，当多个第一DCI的时域位置或者频域位置之间存在一定的规律时，其他控制信息可以包括多个第一DCI的个数以及多个第一DCI的时频位置之间的关系。
根据本公开的实施例，多个第一DCI的时频位置之间的关系可以包括多个第一DCI的时域周期和/或频域周期。例如，在多个第一DCI的时频位置之间的关系包括多个第一DCI的时域周期的情况下，可以认为多个第一DCI的频域位置相同，而第一DCI在时域上以上述周期排列；在多个第一DCI的时频位置之间的关系包括多个第一DCI的频域周期的情况下，可以认为多个第一DCI的时域位置相同，而第一DCI在频域上以上述周期排列；在多个第一DCI的时频位置之间的关系包括多个第一DCI的时域周期和频域周期的情况下，可以认为多个第一DCI在时域上以时域周期排列，在频域上以频域周期排列。
例如，第二DCI包括第一个第一DCI的时频位置，其他控制信息包括时域周期5，则UE可以根据第二DCI确定第一个第一DCI的时频位置，然后确定第二个第一DCI的频域位置与第一个第一DCI的频域位置相同，并将第一个第一DCI的起始符号位置增加5个OFDM符号作为第二个第一DCI的起始符号位置，将第一个第一DCI的持续符号长度作为第二个第一DCI的持续符号长度，从而确定第二个第一DCI的时域位置。
再如，第二DCI包括第一个第一DCI的时频位置，其他控制信息包括频域周期6，则UE可以根据第二DCI确定第一个第一DCI的时频位置，然后确定第二个第一DCI的时域位置与第一个第一DCI的时域位置相同，并将第一个第一DCI的起始子载波位置增加6个子载波作为第二个第一DCI的起始子载波位置，将第一个第一DCI的持续子载波长度作为第二个第一DCI的持续子载波长度，从而确定第二个第一DCI的频域位置。
根据本公开的实施例，多个第一DCI可以位于同一个时隙中，也可以位于不同的时隙中。在上述实施例中，在多个第一DCI位于不同的时隙中的情况下，其他控制信息还可以包括除第二DCI中包括的那个第一DCI之外的各个其他第一DCI所在的时隙。
如上所述，根据本公开的实施例，在多个第一DCI的时频位置分布存在一定的规律的情况下，其他控制信息可以仅包括表示这种规律的关系信息，从而节约开销。
<第三实施例>
根据本公开的实施例，其他控制信息可以包括多个第一DCI中的每个第一DCI的时频位置。本实施例与第一实施例类似，不同之处在于用其他控制信息来携带每个第一DCI的时频位置。也就是说，其他控制信息可以包括表1中所示的内容。例如，其他控制信息可以为例如RRC信令的高层信令，或者可以为除第一DCI和第二DCI的第三DCI。
类似地，其他控制信息隐含指示了数据信道承载的多个第一DCI的个数，即第一DCI被重复发送的次数。也就是说，其他控制信息包括了多少个第一DCI的时频位置，第一DCI就有多少个。
如上所述，在第三实施例中，UE根据其他控制信息可以确定第一DCI的个数以及各个第一DCI的时频位置。在这个实施例中，第二DCI可以与现有标准中PDCCH中承载的DCI的格式和大小兼容，并且由于第二DCI中不包括第一DCI的时频位置，因此第二DCI中用于指示时频位置的比特可以预留。
根据本公开的实施例，在上述三个实施例中，第二DCI还可以包括第一DCI的MCS(Modulation and Coding Scheme，调制编码方案)和/或第一DCI的TCI(Transmission Configuration Indicator，传输配置指示)状态指示。此外，第二DCI还可以包括其他一些与第一DCI的解码有关的信息。
如上详细描述了第二DCI的内容。根据本公开的实施例，第二DCI可以与现有标准中的PDCCH携带的DCI的大小一致，内容兼容，从而减小对现有标准的改变。
下面详细描述第一DCI中的内容。第一DCI可以包括多个数据信道的调度信息。
根据本公开的实施例，多个数据信道的调度信息可以包括与多个数据信道中的每个数据信道的时频位置有关的位置信息。
<第一实施例>
根据本公开的实施例，位置信息可以包括每个数据信道所在的时隙、每个数据信道在一个时隙中的时域位置、以及每个数据信道的频域位置。
根据本公开的实施例，数据信道的频域位置可以包括数据信道的起始子载波位置和持续子载波长度。例如，数据信道的起始子载波位置为1， 持续子载波长度为3，则UE可以确定数据信道的频域位置为标号为1、2和3的子载波。当然，如果频域资源分配的单位为RB或其他单位，也可以用RB或其他单位的标识来指示频域位置。
根据本公开的实施例，可以用数据信道所在的时隙与第一DCI所在的时隙之间的差值来指示数据信道所在的时隙。这样一来，接收到第一DCI的UE可以根据第一DCI所在的时隙以及上述差值来确定数据信道所在的时隙。例如，第一DCI在时隙2中，电子设备100指示上述差值为2，则UE可以确定数据信道在时隙4中。
根据本公开的实施例，可以用数据信道在一个时隙中的起始符号位置和持续符号长度来指示数据信道在一个时隙中的时域位置。例如，电子设备100指示数据信道在一个时隙中的起始符号位置为1，持续符号长度为3，则UE可以确定数据信道在一个时隙中的时域位置为标号为1、2和3的OFDM符号。由此，结合数据信道所在的时隙，UE可以确定数据信道的时域位置为时隙4中的标号为1、2和3的OFDM符号。
根据本公开的实施例，第一DCI可以用如上所述的方式包括每个数据信道时频位置。也就是说，第一DCI的内容可以如下表所示：

其中，M为第一DCI调度的数据信道的个数。
根据本公开的实施例，多个数据信道的调度信息还可以包括上下行指示信息，上下行指示信息指示多个数据信道中的每个数据信道是上行数据信道还是下行数据信道。
根据本公开的实施例，在多个数据信道均为下行数据信道或者均为上行数据信道的情况下，可以用第一DCI中的1比特来指示这样的信息。例如，当该比特位为1时，表示第一DCI调度的多个数据信道均为下行数据信道；当该比特位为0时，表示第一DCI调度的多个数据信道均为上行数据信道。在多个数据信道中的部分为下行数据信道而另一部分为上行数据信道的情况下，针对每个数据信道都可以设置这样的比特位。
根据本公开的实施例，第一DCI中还可以包括数据信道类型指示，以用于指示第一DCI调度的多个数据信道是否为同一类型。例如，可以用1比特来表示这样的信息，在多个数据信道均为下行数据信道或者均为上行数据信道的情况下，该比特位为1；在多个数据信道中的部分为下行数据信道而另一部分为上行数据信道的情况下，该比特位为0。

如上所述，根据本公开的实施例，第一DCI中可以包括每个数据信道的时域位置和频域位置，因此无论各个数据信道在时域和频域上如何分布，第一DCI都可以准确地指示各个数据信道的位置。
<第二实施例>
根据本公开的实施例，位置信息可以包括每个数据信道所在的时隙、多个数据信道中的一个数据信道在一个时隙中的时域位置、以及一个数据信道的频域位置。
根据本公开的实施例，多个数据信道的调度信息还可以包括第一DCI所调度的数据信道的个数。在第一DCI所调度的所有数据信道均为下行数据信道的情况下，多个数据信道的调度信息可以包括第一DCI所调度的所有下行数据信道的个数；在第一DCI所调度的所有数据信道均为上行 数据信道的情况下，多个数据信道的调度信息可以包括第一DCI所调度的所有上行数据信道的个数；在第一DCI所调度的数据信道部分为下行数据信道部分为上行数据信道的情况下，多个数据信道的调度信息可以包括第一DCI所调度的所有下行数据信道的个数以及所有上行数据信道的个数。
如上所述，根据本公开的实施例，第一DCI可以仅包括一个数据信道的时频位置以及其他数据信道所在的时隙。UE在收到这样的第一DCI的情况下，可以认为其他数据信道的频域位置与该一个数据信道的频域位置相同，并且可以认为其他数据信道在一个时隙中的时域位置与该一个数据信道在一个时隙中的时域位置相同，从而确定各个其他数据信道的时域位置。

根据本公开的实施例，多个数据信道的调度信息还可以包括上下行指示信息，上下行指示信息指示多个数据信道中的每个数据信道是上行数据信道还是下行数据信道。
根据本公开的实施例，在多个数据信道均为下行数据信道或者均为上行数据信道的情况下，可以用第一DCI中的1比特来指示这样的信息。例如，当该比特位为1时，表示第一DCI调度的多个数据信道均为下行数据信道；当该比特位为0时，表示第一DCI调度的多个数据信道均为上行数据信道。在多个数据信道中的部分为下行数据信道而另一部分为上行数 据信道的情况下，针对每个数据信道都可以设置这样的比特位。

如上所述，根据本公开的实施例，在多个数据信道的频域位置相同，并且在一个时隙中的时域位置也相同的情况下，第一DCI中可以仅包括一个数据信道的频域位置和在一个时隙中的时域位置，从而可以减小第一DCI的开销。
此外，在上述两个实施例中，第一DCI还可以包括用于指示第一DCI调度的多个数据信道是否连续的指示信息。例如，第一DCI可以包括1比特这样的指示信息。在该指示信息为0的情况下，表示第一DCI调度的多个数据信道不连续；在该指示信息为1的情况下，表示第一DCI调度的多个数据信道连续。
根据本公开的实施例，在第一DCI调度的多个数据信道连续的情况下，第一DCI可以包括第一个数据信道所在的时隙，而无需包括其他数据信道所在的时隙。接收到第一DCI的UE可以根据第一个数据信道所在的时隙确定其他数据信道所在的时隙。这样一来，可以进一步减少第一DCI的开销。
此外，根据本公开的实施例，第一DCI还可以包括以下用于解码数据信道的信息中的一种或多种：各个数据信道的MCS；各个数据信道的TCI状态指示；各个数据信道的标识信息。
由此可见，根据本公开的实施例，可以用数据信道承载包括多个数据信道的调度信息的DCI，用PDCCH承载的DCI指示上述DCI的解码相关信息。这样一来，不会增加UE对PDCCH进行盲检的难度。进一步，用数据信道承载多个这样的DCI。这样一来，由于多次发送DCI，UE可以对多个DCI进行软合并，从而提高了对DCI进行正确译码的概率。此外，可以灵活地设计两个DCI中的内容。总之，根据本公开的技术方案，可以提高包括多个数据信道的调度信息的DCI的传输的可靠性。
<3.用户设备的配置示例>
图10是示出根据本公开的实施例的无线通信系统中的用作用户设备 的电子设备1000的结构的框图。
如图10所示，电子设备1000可以包括解码单元1020和通信单元1010。
这里，电子设备1000的各个单元都可以包括在处理电路中。需要说明的是，电子设备1000既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，电子设备1000可以通过通信单元1010使用数据信道接收多个第一DCI。
根据本公开的实施例，解码单元1020可以对多个第一DCI进行软合并和译码，以确定第一DCI中包括的多个数据信道的调度信息。
由此可见，根据本公开的实施例，电子设备1000可以用数据信道接收包括多个数据信道的调度信息的DCI，不会增加对PDCCH进行盲检的难度。进一步，数据信道承载了多个这样的DCI，电子设备1000可以对多个DCI进行软合并，从而提高了对DCI进行正确译码的概率。
根据本公开的实施例，第一DCI调度的多个数据信道中的每个数据信道可以为上行数据信道或下行数据信道，并且多个数据信道在时域上可以连续或不连续。
根据本公开的实施例，电子设备1000还可以通过通信单元1010接收第二DCI，解码单元1020还可以对控制信道进行盲检和译码以确定第二DCI，并且根据所述第二DCI确定与解码多个第一DCI有关的信息。这里的控制信道可以是PDCCH。
