Description

上行免动态授权传输的方法及装置
本申请要求于2018年09月28日提交国家知识产权局、申请号为201811142702.8、申请名称为“上行免动态授权传输的方法及装置”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，尤其涉及上行免动态授权传输的配置方法及装置。
背景技术
上行免动态授权传输是一种“即来即走”的上行数据发送方法，也即，当终端需要向基站发送数据时，终端直接使用基站预先配置的传输资源以及传输参数等向基站发送数据，而不需要先向基站发送调度请求以及等待基站发送的动态授权。相比于传统的基于“请求-授权”的上行传输方法，上行免动态授权传输具有显著降低信令开销、降低传输时延以及降低终端功耗等有益效果。
新无线接入技术(new radio access technology，NR)系统支持两类上行免动态授权传输，分别是：基于第一类配置授权的物理上行共享信道(physical uplink shared channel，PUSCH)传输(type 1 PUSCH transmission with a configured grant，或type 1 configured grant configuration，或type 1 configured grant PUSCH transmission)，和基于第二类配置授权的PUSCH传输(type 2 PUSCH transmission with a configured grant，或type 2 configured grant configuration，或type 2 configured grant PUSCH transmission)。
其中，基于第二类配置授权的PUSCH传输的配置方式分为以下两步：首先，基站通过高层参数向终端配置包括时域资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、混合自动重传请求(hybrid automatic repeat request，HARQ)进程数、解调用参考信号相关参数、调制与编码策略(modulation and coding scheme，MCS)表格、资源块(resource block group，RBG)组大小等在内的传输资源和传输参数；之后，基站向终端发送配置的调度(Configured Scheduling，CS)-无线网络临时标识(radio network temporary identity，RNTI)加扰的下行控制信息(downlink control information，DCI)(例如configuration-specific DCI)，以使得终端激活基于第二类配置授权的PUSCH传输，并同时配置包括时域资源、频域资源、解调参考信号(demodulation reference signal，DMRS)、MCS等在内的传输资源和传输参数。需要说明的是，该第二类配置授权的PUSCH传输在被激活后才能使用。
NR系统支持每个带宽部分(bandwidth part，BWP)上配置多个基于第二类配置授权的PUSCH传输。但是，configuration-specific DCI仅能使终端激活/去激活一个基于第二类配置授权的PUSCH传输。因此，若为了使用一个BWP上的多个基于第二类配置授权的PUSCH传输，基站需要向终端下发多个DCI，以使得终端激活/去激活该BWP上的多个基于第二类配置授权的PUSCH传输。但是，这样一来，基站与终端之间的信令开销较大。
发明内容
本申请提供一种上行免动态授权传输的配置方法及装置，用于解决在上行免动态授权传输的配置过程中，基站多次下发DCI所带来的信令开销过大的问题。
为达到上述目的，本申请提供如下技术方案：
第一方面，提供一种上行免动态授权传输的配置方法，包括：终端接收下行控制信息，下行控制信息包含多个指示信息，每一个指示信息对应一个第二类型配置的授权配置，该指示信息用于指示终端对指示信息对应的第二类型配置的授权配置执行操作，操作包括：激活、去激活或者保持状态；之后，终端根据下行控制信息，对多个第二类型配置的授权配置执行对应的操作。可见，基于本申请提供的技术方案，在上行免动态授权传输的配置过程中，网络设备通过下发一个下行控制信息，可以使得终端激活/去激活多个第二类型配置的授权配置，从而减少了网络设备与终端之间的信令开销。
作为一种示例，指示信息包含第一比特域和第二比特域；指示信息用于指示终端对指示信息对应的第二类型配置的授权配置执行操作，至少包括以下情形之一：
(1)若第一比特域的取值为第一预设值，则指示信息用于指示终端激活指示信息对应的第二类型配置的授权配置；
(2)若第一比特域的取值为第二预设值，且第二比特域的取值为第三预设值，则指示信息用于指示终端去激活指示信息对应的第二类型配置的授权配置；
(3)若第一比特域的取值为第二预设值，且第二比特域的取值不是第三预设值，则指示信息用于指示终端保持指示信息对应的第二类型配置的授权配置的状态。
可选的，第二比特域用于指示上述指示信息对应的第二类型配置的授权配置的时域偏置值。
一种可能的设计中，指示信息还用于指示以下参数的一种或多种：解调参考信号、调制与编码策略以及时频资源。

具体实施方式
在介绍本申请实施例提供的方法之前，下面先对本申请实施例涉及的一些概念进 行简单介绍。
(1)BWP
由于同一服务小区中不同终端的发射或接收能力可能是不同的，因此系统可以为每个终端配置相应的带宽，这一部分配置给终端的带宽称为BWP。BWP可以理解为终端的工作带宽，终端在自己的BWP上传输或者接收数据。
终端在同一服务小区上可以配置一个或多个BWP。需要说明的是，不同BWP可以采用不同的子载波间隔(subcarrier spacing，SCS)、循环前缀(cyclic prefix，CP)等，以适应不同类型的业务。
(2)时域偏置值
所述时域偏置值用于确定用于上行免动态授权传输的时域资源的位置。例如，终端在时隙n上接收到DCI，该DCI携带的时域偏置值为k个时隙，则用于上行免动态授权传输的时域资源的起始时隙为时隙n+k。
(3)上行免动态授权传输
上行免动态授权传输：终端的上行传输不需要通过网络设备的调度完成。具体地，当上行数据到达时，终端不需要向网络设备发送调度请求(scheduling request，SR)并等待网络设备的动态授权(dynamic grant)，而是可以直接使用网络设备预先分配的传输资源和指定的传输参数向网络设备发送上行数据。
在NR中，上行免动态授权传输可以分为两类。即，基于第一类型配置授权的PUSCH传输和基于第二类型配置授权的PUSCH传输。
网络设备可以通过高层信令，如携带在无线资源控制(radio resource control，RRC)消息中的配置的授权配置控制元素(ConfiguredGrantConfig information element，ConfiguredGrantConfig IE)，配置configured grant configuration。终端可以根据ConfiguredGrantConfig IE中所配置的参数确定该ConfiguredGrantConfig IE所配置的configured grant configuration是第一类型配置的授权配置(type1 configured grant configuration)还是第二类型配置的授权配置(type 2configured grant configuration)。
下面详细说明这两类上行免动态授权传输。
在基于第一类型配置授权的PUSCH传输中，type1 configured grant configuration中配置的参数例如可以包括时频资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、HARQ进程数、DMRS相关参数、MCS表格、资源块组(resource block group，RBG)大小、时域资源、频域资源、MCS等在内的全部传输资源和传输参数。终端在接收到该高层参数后，可以直接使用所配置的传输参数在所配置的时频资源上传输PUSCH。因此，这种传输方案也可以称为全RRC配置的上行授权(fully RRC-configured UL grant)。
在基于第二类型配置授权的PUSCH传输中，第二类型配置的授权配置(type2 configured grant configuration)中配置的参数例如可以包括时频资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、HARQ进程数、DMRS相关参数、MCS表格、RBG组大小等在内的传输资源和传输参数。在一示例中，第二类型配置的授权配置中配置的具体参数可以参考3GPP TS38.331中的相关内容。此后，网络设备可以通过DCI激活一个type2 configured grant configuration 以进行PUSCH传输。该DCI可携带所激活的type2 configured grant configuration的索引。该DCI还可以进一步配置时域资源、频域资源、DMRS、MCS等在内的其他传输资源和传输参数。因此，终端在接收到高层参数后，并不能立即进行PUSCH传输，而需要在接收到DCI之后，才能够确定所激活的type2 configured grant configuration，并结合DCI中所指示的传输资源和传输参数，基于所配置的传输参数在所配置的时频资源上传输PUSCH。网络设备可以通过例如DCI格式0_0/0_1激活type2 configured grant configuration。
换句话说，终端激活某一个type2 configured grant configuration，也就是使得这个type2 configured grant configuration中的参数有效。终端可以结合该type2 configured grant configuration中的参数和激活该配置的授权配置的DCI中的参数，确定用于传输PUSCH的传输资源和传输参数，从而可以进行PUSCH传输。因此，当DCI激活一个配置的授权配置时，可以认为该DCI用于激活基于该type2 configured grant configuration的免动态授权传输。
此外，网络设备也可以通过DCI去激活type2 configured grant configuration。具体地，该DCI中可携带去激活的type2 configured grant configuration的索引。终端可以根据该索引确定去激活的type2 configured grant configuration。网络设备可以通过例如DCI格式0_0去激活type2 configured grant configuration。
换句话说，终端去激活(或者说，释放)一个type2 configured grant configuration，也就是使得这个type2 configured grant configuration中的参数失效，使得终端不能基于该type2 configured grant configuration进行上行免动态授权传输。因此，当DCI去激活一个配置的授权配置时，可以认为该DCI用于去激活基于该type2 configured grant configuration的上行免动态授权传输。
在本申请实施例中，终端去激活一个type2 configured grant configuration，包括两种方式：一种为终端暂停(suspend)type2 configured grant configuration，也即使得这个type2 configured grant configuration中的参数失效，但是终端中还保存着DCI指示的传输资源和传输参数。这样一来，若基站再次下发DCI以重新激活该处于暂停状态的type2 configured grant configuration，该DCI可以不携带时域资源、频域资源、DMRS、MCS等在内的其他传输资源和传输参数的指示信息，以减少传输开销。另一种为终端清除(clear)type2 configured grant configuration，也即使得这个type2 configured grant configuration中的相关参数失效，并且终端不保存DCI指示的传输资源和传输参数。这样一来，若基站再次下发DCI以重新激活该处于暂停状态的type2 configured grant configuration，该DCI需要携带时域资源、频域资源、DMRS、MCS等在内的其他传输资源和传输参数的指示信息，才能使得终端可以使用该type2 configured grant configuration进行上行免动态授权传输。
在本申请的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等 字样也并不限定一定不同。
在本申请的描述中，“指示”可以包括直接指示和间接指示，也可以包括显式指示和隐式指示。将某一信息(如下文所述的配置信息)所指示的信息称为待指示信息，则具体实现过程中，对所述待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示所述待指示信息，如所述待指示信息本身或者所述待指示信息的索引等。也可以通过指示其他信息来间接指示所述待指示信息，其中该其他信息与所述待指示信息之间存在关联关系。还可以仅仅指示所述待指示信息的一部分，而所述待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。

如图3所示，本申请实施例提供一种上行免动态授权传输的配置方法，包括以下步骤：
S101、网络设备生成group DCI。其中，group DCI用于指示终端对至少一个type2 configured grant configuration进行操作。
需要说明的是，group DCI仅是一个示例性的名称，不构成任何限定。group DCI也可以有其他的名称，例如DCI forma 2_x，或DCI format x，本申请实施例对此不作任何限制。
其中，所述操作包括：激活、去激活以及保持状态。
在本申请实施例中，type2 configured grant configuration存在以下三种状态：激活状态、去激活状态以及暂停状态。其中，当type2 configured grant configuration处于激活状态时，终端能够使用该type2 configured grant configuration进行上行免动态授权传输。当type2 configured grant configuration处于去激活状态或者暂停状态时，终端不能够使用该type2 configured grant configuration进行上行免动态授权传输。暂停状态与去激活状态的区别在于：当type2 configured grant configuration处于暂停状态时，终端保存有下行控制信息所指示的关于该type2 configured grant configuration的传输资源和传输参数的相关信息。
因此，上述保持type2 configured grant configuration的状态是指，不对type2 configured grant configuration的状态进行改变。例如，若在终端接收到下行控制信息之前type2 configured grant configuration处于激活状态，则在终端接收到下行控制信息之后type2 configured grant configuration同样处于激活状态。
一种可选的实现方式中，group DCI包含一个第一指示信息，所述第一指示信息用于指示终端对所述至少一个type2 configured grant configuration进行操作。
示例性的，该第一指示信息以至少一个比特进行指示。例如，当第一指示信息包含的至少一个比特全为0时，该第一指示信息用于指示终端去激活所述至少一个type2 configured grant configuration。又例如，当第一指示信息包含的至少一个比特全为1时，该第一指示信息用于指示终端激活所述至少一个type2 configured grant configuration。
需要说明的是，group DCI中携带所述至少一个type2 configured grant configuration的索引。或者，上述至少一个type2 configured grant configuration是预先定义的。例如，所述至少一个type2 configured grant configuration包含终端当前使用的BWP上配置的所有type2 configured grant configuration。又例如，所述至少一个type2 configured grant configuration包含处于暂停状态的type2 configured grant configuration。又例如，所述至少一个type2 configured grant configuration包含处于去激活状态的type2 configured grant configuration。又例如，所述至少一个type2 configured grant configuration包含处于激活状态的type2 configured grant configuration。
另一种可选的实现方式中，group DCI包含至少一个第二指示信息，每一个第二指示信息对应一个type2 configured grant configuration，所述第二指示信息用于指示终端对所述第二指示信息对应的type2 configured grant configuration进行操作。
需要说明的是，第二指示信息与type2 configured grant configuration的对应关系可以以显式的方式来表示。例如，第二指示信息中携带type2 configured grant configuration 的索引，以说明该第二指示信息对应的type2 configured grant configuration。或者，第二指示信息与type2 configured grant configuration的对应关系可用以隐式的方式来表示。例如，第二指示信息在group DCI中的位置与type2 configured grant configuration的索引存在对应关系，从而终端可以根据第二指示信息在group DCI中的位置，确定第二指示信息对应的type2 configured grant configuration。其中，第二指示信息在group DCI中的位置与type2 configured grant configuration的索引之间的对应关系可以是预先设置的，也可以是网络设备通知终端的。
作为一种示例，若所述第二指示信息包含第一比特域和第二比特域，所述第二指示信息用于指示终端对所述第二指示信息对应的type2 configured grant configuration进行操作，至少包括以下情形之一：
(1)若所述第一比特域的取值为第一预设值，则所述第二指示信息用于指示所述终端激活所述第二指示信息对应的type2 configured grant configuration。
(2)若所述第一比特域的取值为第二预设值，且所述第二比特域的取值为第三预设值，则所述第二指示信息用于指示所述终端去激活所述第二指示信息对应的type2 configured grant configuration。
(3)若所述第一比特域的取值为第二预设值，且所述第二比特域的取值不是第三预设值，则所述第二指示信息用于指示所述终端保持所述第二指示信息对应的type2 configured grant configuration的状态。
作为另一种示例，若所述第二指示信息包含第一比特域和第二比特域，所述第二指示信息用于指示终端对所述第二指示信息对应的type2 configured grant configuration进行操作，至少包括以下情形之一：
(1)若所述第一比特域的取值为第一预设值，则所述第二指示信息用于指示所述终端激活所述第二指示信息对应的type2 configured grant configuration。
(2)若所述第一比特域的取值为第二预设值，且所述第二比特域的取值不是第三预设值，则所述第二指示信息用于指示所述终端去激活所述第二指示信息对应的type2 configured grant configuration。
(3)若所述第一比特域的取值为第二预设值，且所述第二比特域的取值为第三预设值，则所述第二指示信息用于指示所述终端保持所述第二指示信息对应的type2 configured grant configuration的状态。
作为另一种示例，若所述第二指示信息包含第一比特域，所述第二指示信息用于指示终端对所述第二指示信息对应的type2 configured grant configuration进行操作，至少包括以下情形之一：
(1)若所述第一比特域的取值为第一预设值，则所述第二指示信息用于指示所述终端激活所述第二指示信息对应的type2 configured grant configuration。
(2)若所述第一比特域的取值为第二预设值，则所述第二指示信息用于指示所述终端去激活所述第二指示信息对应的type2 configured grant configuration。
(3)若所述第一比特域的取值为第四预设值，则所述第二指示信息用于指示所述终端保持所述第二指示信息对应的type2 configured grant configuration的状态。
作为另一种示例，若所述第二指示信息包含第二比特域，所述第二指示信息用于 指示终端对所述第二指示信息对应的type2 configured grant configuration进行操作，至少包括以下情形之一：
(1)若所述第二比特域的目标比特的取值为第五预设值，则所述指示信息用于指示所述终端去激活所述指示信息对应的type2 configured grant configuration。可选的，所述目标比特为最高有效位比特(most significant bit，MSB)。
(2)若所述第二比特域的目标比特的取值为第六预设值，且所述第二比特域中除目标比特之外的其他比特的取值为第七预设值，则所述第二指示信息用于指示所述终端去激活所述第二指示信息对应的type2 configured grant configuration。
(3)若所述第二比特域的目标比特的取值为第六预设值，且所述第二比特域中除目标比特之外的其他比特的取值不是第七预设值，则所述指示信息用于指示所述终端保持所述指示信息对应的type2 configured grant configuration的状态。
作为另一种示例，若所述第二指示信息包含第二比特域，所述第二指示信息用于指示终端对所述第二指示信息对应的type2 configured grant configuration进行操作，至少包括以下情形之一：
(1)若所述第二比特域的目标比特的取值为第五预设值，则所述指示信息用于指示所述终端去激活所述指示信息对应的type2 configured grant configuration。
(2)若所述第二比特域的目标比特的取值为第六预设值，且所述第二比特域中除目标比特之外的其他比特的取值不是第七预设值，则所述第二指示信息用于指示所述终端去激活所述第二指示信息对应的type2 configured grant configuration。
(3)若所述第二比特域的目标比特的取值为第六预设值，且所述第二比特域中除目标比特之外的其他比特的取值为第七预设值，则所述指示信息用于指示所述终端保持所述指示信息对应的type2 configured grant configuration的状态。
在本申请实施例中，上述第二比特域可以用于指示第二指示信息对应的type2 configured grant configuration的时域偏置值。
可选的，所述group DCI包含的多个第二指示信息分别对应于不同的服务小区。例如，如图4所示，第二指示信息1对应服务小区1，第二指示信息1用于指示终端激活type2 configured grant configuration 1；第二指示信息3对应服务小区2，第二指示信息3用于指示终端去激活type2 configured grant configuration 2。
在本申请实施例中，第二指示信息与服务小区的对应关系以显示的方式来表示。例如，第二指示信息包含服务小区的标识。或者，第二指示信息与服务小区的对应关系以隐式的方式来表示。例如，第二指示信息在group DCI的位置与服务小区的标识存在对应关系，从而终端可以根据该第二指示信息在group DCI中的位置，确定该第二指示信息对应的服务小区。其中，第二指示信息在group DCI的位置与服务小区的标识之间的对应关系可以是预先设置的，也可以是网络设备通知终端的。
作为一种可能的实现方式，如图5或图6所示，所述group DCI还可以包含BWP指示信息，所述BWP指示信息用于指示终端应使用的BWP，所述BWP指示信息可以包含BWP的索引。需要说明的是，若BWP指示信息所指示的BWP不是终端当前使用的BWP，则终端应该去激活当前使用的BWP，并激活BWP指示信息所指示的BWP。例如，终端当前使用BWP1，终端接收到的group DCI中BWP指示信息用于指 示终端使用BWP2，则终端去激活BWP1，激活BWP2。另外，需要说明的是，在去激活BWP1的过程中，终端还需要去激活BWP1上处于激活状态的type2 configured grant configuration。这样一来，网络设备可以通过group DCI指示终端切换BWP，而无需以其他信令指示终端切换BWP，节省了信令开销。
作为一种可能的实现方式，所述group DCI还可以用于指示至少一个type2 configured grant configuration的传输参数。可选的，所述传输参数包含以下至少一项：DMRS、MCS以及时频资源。其中，时频资源包括上行免动态授权传输在时隙中起始OFDM符号的编号，以及上行免动态授权传输占用OFDM符号的数目。
应理解的是，指示DMRS是指指示用于生成DMRS的相关参数配置，并不是指示DMRS本身。用于生成DMRS的相关参数可以参考现有的NR协议中的相关内容。
其中，所述group DCI用于指示至少一个type2 configured grant configuration的传输参数，至少包括以下情形之一:
情形一、如图7或图8所示，所述group DCI包含一个第一传输参数比特域，该第一传输参数比特域用于指示至少一个type2 configured grant configuration的传输参数。也即，该第一传输参数比特域所指示的传输参数是多个type2 configured grant configuration公用的。
情形二、如图9所示，所述group DCI中的第二指示信息可以包含第二传输参数比特域，该第二传输参数比特域用于指示该第二指示信息对应的type2 configured grant configuration的传输参数。也即，该第二传输参数比特域所指示的传输参数是该第二指示信息对应的type2 configured grant configuration专用的。在本申请实施例中，第二指示信息可以包含第二传输参数比特域，也可以不包含第二传输比特域，本申请实施例对此不作具体限定。例如，若第二指示信息用于指示终端去激活type2 configured grant configuration，或者，第二指示信息用于指示终端保持type2 configured grant configuration的状态，则第二指示信息可以不包含第二传输参数比特域，从而减少group DCI的传输开销。
S102、网络设备向终端发送group DCI。
一种实现方式中，若group DCI可以是终端专用的，也即网络设备仅将该group DCI发送给该终端。或者，若group DCI可以是公用的，则网络设备将该group DCI发送给服务小区中的多个终端。
S103、终端接收group DCI。
可选的，若group DCI是专用的，终端从UE特定搜索空间中盲检PDCCH，以获取该group DCI。若group DCI是公用的，终端从公共搜索空间中盲检PDCCH，以获取该group DCI。
S104、终端根据group DCI，对至少一个type2 configured grant configuration执行操作。
基于上述技术方案，在上行免动态授权传输的配置过程中，网络设备通过下发一个下行控制信息，可以使得终端激活/去激活多个第二类型配置的授权配置，从而减少了网络设备与终端之间的信令开销。
作为一种可能的实现方式，如图10所示，本申请实施例提供的技术方案在步骤 S102之前，还包括：步骤S201。需要说明的是，本申请实施例并不对步骤S101与步骤S201的执行顺序进行限定。也即，网络设备可以先执行步骤S101，再执行步骤S201。或者，网络设备先执行步骤S201，再执行步骤S101。又或者，网络设备同时执行步骤S101和步骤S201。
S201、网络设备向终端发送group DCI的配置信息。
一种可选的实现方式中，网络设备通过无线资源控制(Radio resource control，RRC)信令或者媒体接入控制(Media Access Control，MAC)信令或者物理层控制信令向终端发送group DCI的配置信息。
可选的，所述group DCI的配置信息至少包括以下参数中的一种或者多种：
(1)RNTI。
(2)group DCI的有效载荷大小。
(3)第一服务小区列表，所述第一服务小区列表用于指示应用所述group DCI的服务小区。换句话说，所述第一服务小区列表用于指示所述group DCI生效的服务小区。也即，若终端接入第一服务小区列表中的服务小区，终端可以根据该group DCI，对至少一个type2 configured grant configuration执行对应的操作。
(4)第二服务小区列表，所述第二服务小区列表用于指示不应用所述group DCI的服务小区。换句话说，所述第二服务小区列表用于指示所述group DCI不生效的服务小区。也即，若终端接入第二服务小区列表中的服务小区，终端不可以根据该group DCI，对至少一个type2 configured grant configuration执行对应的操作。
可以理解的是，所述group DCI的配置信息还可以包含其他参数，本申请实施例对此不作具体限定。
可选的，第二服务小区列表包括：小区标识。
可选的，第一服务小区列表包括：小区标识、第一type2 configured grant configuration列表和/或第二type2 configured grant configuration列表。其中，所述第一type2 configured grant configuration列表用于指示支持应用所述group DCI的type2 configured grant configuration。也即，终端可以根据group DCI，对第一type2 configured grant configuration列表中的type2 configured grant configuration执行对应的操作。所述第二type2 configured grant configuration列表用于指示不支持应用所述group DCI的type2 configured grant configuration。也即，终端不可以根据group DCI，对第二type2 configured grant configuration列表中的type2 configured grant configuration执行对应的操作。
可选的，所述第一type2 configured grant configuration列表包括：type2 configured grant configuration的索引。需要说明的是，当网络设备生成的group DCI包含至少一个第二指示信息时，所述第一type2 configured grant configuration列表还包括：type2 configured grant configuration对应的第二指示信息在group DCI中的位置。
可选的，所述第二type2 configured grant configuration列表包括：type2 configured grant configuration的索引。
S202、终端接收网络设备发送的group DCI的配置信息。
相应的，在终端接收到group DCI的配置信息的情况下，本申请实施例提供的技 术方案中步骤S103可替换为步骤S203。
S203、终端根据group DCI的配置信息，接收group DCI。
基于图10所示的技术方案，网络设备通过向终端下发group DCI的配置信息，以使得终端能够顺利接收group DCI。

S301、网络设备向终端发送多个configuration-specific DCI，以使得终端接收多个configuration-specific DCI。
