下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开的实施例提供了一种时域配置信息指示方法、装置、终端及网络侧设备,用以解决终端在某一时刻的传输方向无法更改的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图1所示,本公开的实施例提供了一种时域配置信息指示方法,应用于终端,具体包括以下步骤:
步骤101、检测网络侧设备发送的时域配置信息;
步骤102、在检测到所述时域配置信息的情况下,根据所述时域配置信息确定时间单元的传输配置;
其中,所述传输配置包括以下至少一项:
1)所述时间单元被配置上行(Uplink,UL)子带;
2)所述时间单元被配置下行(Downlink,DL)子带;
3)所述时间单元的传输方向。
该实施例中,时域配置信息可以用于指示时间单元的传输方向、该时间单元是否被配置了上行或者下行子带。若终端检测到该时域配置信息,则可 以根据所述时域配置信息确定时间单元的传输配置,例如:确定某个时间单元是否被配置了上行子带或者下行子带,或者确定某个时间单元的传输方向。
以终端根据时域配置信息确定时间单元是否被配置上行子带或者下行子带为例,所述时间单元被配置的子带可以与该时间单元的传输方向相反,例如:时域配置信息可以指示对上行时间单元配置了下行子带,终端可以在该上行时间单元进行下行接收,也可以不进行下行接收;或者,所述时域配置信息可以指示下行时间单元配置了上行子带,终端可以在该下行时间单元进行上行传输,也可以不进行上行传输。
以终端根据时域配置信息确定时间单元的传输方向为例,所述时间单元被配置的传输方向可以与该时间单元的原传输方向相反,例如:时域配置信息可以指示终端在上行时间单元进行下行接收,即在上行时间单元上的下行子带上接收下行;或者,时域配置信息可以指示终端在下行时间单元进行上行传输,即在下行时间单元上的上行子带上传输上行。
需要说明的是,本公开实施例所述的上行时间单元是通过目标信息确定为上行的时间单元,下行时间单元是通过目标信息确定为下行的时间单元。所述目标信息是以下信息中的部分或者全部:上行和下行通用配置信息、上行和下行专用配置信息、DCI格式2-0中的SFI。
其中,所述时间单元可以是以下任意一种:帧(frame)、子帧(sub-frame)、时隙(slot)、符号(symbol)等。
当前研究是基于网络侧具备同时发送和接收的能力(简称双工能力),即网络侧设备在同一时刻与不同的用户设备(User Equipment,UE)分别进行上行和下行接收;UE侧不具备双工能力,即UE在某一时刻仅能传输上行或者接收下行,传输方向无法更改。本公开的实施例,终端在检测到网络侧设备配置的时域配置信息的情况下,根据时域配置信息确定时间单元是否被配置上行子带或者下行子带,或者根据时域配置信息确定时间单元的传输方向,即时间单元的传输方向是可变的,实现了对时间单元的传输方向的动态指示。
在一些实施例中,所述时域配置信息承载在预定下行控制信息DCI中,可以通过预定格式(reserved format)指示;
其中,预定DCI包括以下至少一项:
1)所述时域配置信息对应的专用DCI格式;即针对所述时域配置信息设计的专用DCI格式。
2)DCI格式2-0(DCI format 2-0),网络侧设备可以通过DCI format 2-0向终端发送时域配置信息。
在一些实施例中,所述时域配置信息指示以下一种时域范围内的时间单元的传输配置;
1)全部时隙;所述时域配置信息可以应用于全部slot中的时间单元,即指示全部时隙内的时间单元的传输配置。
2)无线资源控制RRC指示的时域范围;所述时域配置信息可以应用于RRC指示的子带全双工(sub-Band Full Duplex,SBFD)的时域范围,即指示RRC指示的SBFD时域范围内的时间单元的传输配置;或者,所述时域配置信息可以应用于RRC指示的其他时域范围,即RRC指示所述时域配置信息生效时间范围,所述时域配置信息在所述生效时间范围内的时间单元有效。
3)预定义的时域范围;所述时域配置信息可以应用于协议中预定义的时域范围,即指示预定义时域范围内的时间单元的传输配置。
4)灵活子带对应的时域范围。网络侧设备可以在某些时间单元配置灵活子带,例如在部分下行(Downlink,DL)/灵活(Flexible,F)symbol上面配置(Flexible)上行子带,在所述时域范围内的时间单元的传输配置是灵活的,可以动态改变传输配置,因此称为灵活子带。时域配置信息仅应用于配置了灵活子带的时间单元。
作为一个可选实施例,所述时域配置信息用于指示所述时间单元的传输方向是第一传输方向;
所述第一传输方向与目标信息指示的所述时间单元的第二传输方向相反;或者,所述第一传输方向与目标信息指示的所述时间单元的第二传输方向相同。
该实施例中,时域配置信息可以指示时间单元的传输方向,其中,时域配置信息指示的传输方向可以与该时间单元的原传输方向相反也可能相同,即网络侧设备可以通过时域配置信息改变时间单元的传输方向。以第一传输方向与第二传输方向相反为例,例如:时间单元根据目标信息指示是上行时 间单元,网络侧设备可以通过时域配置信息指示该时间单元进行下行接收,即在该时间单元的下行子带进行下行接收;或者,时间单元根据目标信息指示是下行时间单元,网络侧设备可以通过时域配置信息指示该时间单元进行上行传输,即在该时间单元的上行子带进行上行传输。
网络侧设备通过UE组专有的时域配置信息,可以将第一传输方向(上行或者下行)指示为第二传输方向(下行或者上行),或者将第二传输方向回退到第一传输方向,实现对时间单元的传输方向的动态配置。其中第一传输方向可以为目标信息中指示的U(这里表示上行)或D(这里表示下行),第二传输方向与第一传输方向相反,即时域配置信息将目标信息指示为U/D的时间单元的传输方向指示为D/U。
作为一个可选实施例,所述时域配置信息用于指示所述时间单元被配置上行子带或者指示所述时间单元被配置下行子带;
其中,若目标信息指示所述时间单元的传输方向是上行,则所述时域配置信息指示所述时间单元被配置下行子带;
若目标信息指示所述时间单元的传输方向是下行,则所述时域配置信息指示所述时间单元被配置上行子带。
该实施例中,网络侧设备通过时域配置信息指示时间单元是否被配置上行子带或者下行子带。在一些实施例中,若时间单元被配置了上行子带或者下行子带,该时间单元的传输方向可以与被配置的子带传输方向相同,也可以不同。例如:若目标信息指示时间单元的传输方向是上行,例如该时间单元是上行传输单元,网络侧设备可以通过时域配置信息指示该时间单元被配置下行子带,则终端可以在该时间单元进行下行接收(也可以不进行下行接收);或者,若目标信息指示时间单元的传输方向是下行,例如该时间单元是上行时间单元,网络侧设备可以通过时域配置信息指示该时间单元被配置上行子带,则终端可以在该时间单元进行上行传输(也可以不进行上行传输)。
在一些实施例中,所述目标信息包括以下信息中的部分或者全部:
1)上行和下行通用配置信息;以TDD上行和下行通用配置信息为例,该信息例如:tdd-UL-DL-configurationCommon。
2)上行和下行专用配置信息;以TDD上行和下行专用配置信息为例, 该信息例如:tdd-UL-DL-ConfigurationDedicated。
3)DCI格式2-0中的SFI。
该实施例中,网络侧设备在给终端配置时域配置信息之前,通过所述目标信息配置时间单元的传输方向,例如通过tdd-UL-DL-configurationCommon,或者通过tdd-UL-DL-ConfigurationDedicated,或者通过DCI format2-0中的SFI配置终端在某个时间单元上的传输方向。网络侧设备可以通过时域配置信息改变上述目标信息配置的时间单元的传输方向。
在一些实施例中,所述时域配置信息通过以下至少一种方式指示:
1)预定义的数值;时域配置信息可以指示为预定义的数值,例如0和1,不同数值指示的信息不同。
或者,
2)预定义的符号,时域配置信息可以指示为预定义的符号,不同符号指示的信息不同。例如:符号U表示上行,符号D表示下行,符号F表示灵活方向,符号X表示时间单元被配置上行子带或者下行子带,需要说明的是,该实施例列举的符号以及含义仅为示例,不作具体限定。
作为一个可选实施例,在通过预定义的数值指示所述时域配置信息的情况下,所述根据所述时域配置信息确定时间单元的传输配置,包括以下至少一项:
(1)若第一时间单元对应的数值是第一值,则根据目标信息确定所述第一时间单元的传输方向;
(2)若第一时间单元对应的数值是第二值,则:确定所述第一时间单元被配置第一子带;或者,确定所述第一时间单元被配置第一子带且所述第一时间单元的传输方向与目标信息指示的传输方向相反;或者,根据子带全双工的配置信息确定所述第一时间单元的传输配置;其中,所述第一子带是上行子带或者下行子带。
以第一值是0、第二值是1、时间单元是符号为例,若网络侧设备指示某个符号对应的数值是0,表示根据目标信息确定该符号的传输方向,如根据tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项确定该符号的传输方向,即在该符号上面无子带,UE根据被配置 和/或接收到的tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项确定这个符号的传输方向是D,或者是U,或者是灵活方向。
若网络侧设备指示某个符号对应的数值是1,表示该符号被配置了上行子带或者下行子带,或者表示该符号被配置了上行子带或下行子带,且该符号的传输方向是上行或下行,或者表示该符号的传输配置根据子带全双工的配置信息确定。其中,所述符号被配置的是上行子带还是下行子带,可以根据该目标信息指示的该符号的传输方向确定,例如:tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示该符号是上行符号,若网络侧设备指示该符号对应的数值是1,则表示该符号被配置下行子带,网络侧设备也可以指示此时该时间单元的传输方向是下行;若tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示该符号是下行符号,若网络侧设备指示该符号对应的数值是1,则表示该符号被配置上行子带,网络侧设备也可以指示该符号的传输方向是上行。
该实施例中,在根据子带全双工的配置信息确定第一时间单元的传输配置时,该子带全双工的配置信息可以是网络侧设备半静态配置的(如通过RRC信令配置),在该情况下,相当于网络侧设备通过DCI format 2-0动态确认半静态配置的子带全双工配置信息,即在符号对应的数值是1时的时间单元根据RRC配置的子带全双工的时域信息确定传输配置。
在一些实施例中,所述根据子带全双工的配置信息确定所述第一时间单元的传输配置,包括以下至少一项:

2)若所述子带全双工的配置信息指示所述第一时间单元的传输方向为下行,则确定所述第一时间单元的传输方向是下行;
3)若所述子带全双工的配置信息指示所述第一时间单元被配置第二子带,则确定所述第一时间单元被配置第二子带,所述第二子带是上行子带或者下行子带。具体地,所述第一时间单元被配置的是上行子带还是下行子带可以 根据目标信息指示的该第一时间单元的传输方向确定,例如;若tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示该第一时间单元是下行,则第二子带可以是上行子带;若tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示该第一时间单元是上行,则第二子带可以是下行子带。
下面举例说明通过预定义的数值指示时域配置信息的实现方法。
对于slot n,DCI format 2-0通过SFI指示的时域配置信息为00001111111111,由于第1至第4个symbol对应的数值是0,则对于第1至第4个symbol,传输方向根据被配置和/或接收的tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项确定。第5至第14个symbol对应的数值是1,则对于第5至第14个symbol,包含UL子带或DL子带(具体为UL子带还是DL子带,可以根据被配置和/或接收的tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI指示的符号的传输方向确定,如果指示该symbol为D,则该符号被配置为UL子带;如果指示该symbol为U,则该符号被配置DL子带。也可以根据其他方法进一步确定,在此不做限定)。
或者,对于第5至第14个symbol,包含UL子带或DL子带,且第5至第14个symbol的传输方向是上行或者下行。具体被配置UL子带还是DL子带,可以根据被配置和/或接收的tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示的符号的传输方向确定,如果指示该symbol为D,则该符号被配置为UL子带;如果指示该symbol为U,则该符号被配置DL子带。也可以根据其他方法进一步确定,在此不做限定。
或者,对于第5至第14个symbol,根据RRC配置的子带全双工的配置信息确定,例如:该slot的子带全双工的配置信息指示为DDDDDDXXXXUUUU,其第5个和6个符号对应的配置是D,则表示第5个符号和6个符号的传输方向是下行,第11个符号至第14个符号对应的配置是U,则表示第11个符号至第14个符号的传输方向是上行。第7个符号至第10个符号指示为X,表示该部分符号被配置第二子带,第二子带是上行 子带还是下行子带,可以根据被配置和/或接收的tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示的符号的传输方向确定,如果指示某个符号为D,则该符号被配置为UL子带;如果指示某个符号为U,则该符号被配置DL子带。也可以根据其他方法进一步确定,在此不做限定。

所述第一符号可以是预定义的,与指示上行的符号(如U)、指示下行的符号(如D)以及指示灵活方向的符号(如F)均不同的符号。若网络侧设备配置某个时间单元对应的符号是第一符号,则表示该时间单元被配置上行 子带或者下行子带,或所述时间单元被配置上行子带或者下行子带且所述时间单元的传输方向为上行或者下行,或者表示该时间单元的传输配置根据子带全双工的配置信息确定。
在一些实施例中,所述时间单元被配置上行子带还是下行子带可以根据目标信息指示的该时间单元的传输方向确定。例如:tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示第二时间单元的传输方向下行,则该第二时间单元被配置上行子带;如果指示第二时间单元的传输方向是上行,则该第二时间单元被配置下行子带。

3)若所述子带全双工的配置信息指示所述第二时间单元被配置第四子带,则确定所述第二时间单元被配置第四子带,所述第四子带是上行子带或者下行子带。具体地,所述第二时间单元被配置的是上行子带还是下行子带可以根据目标信息指示的该第二时间单元的传输方向确定,例如;若终端被配置或者接收到的tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示该第二时间单元是下行,则第四子带可以是上行子带;若tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示该第二时间单元是上行,则第四子带可以是下行子带。
例如:将网络侧设备通过“U/D/F/X”等符号指示时间单元的时域配置信息,即在U、D、F三种符号类型的基础上增加一种指示符号X(仅为示例,也可以为其他符号),该符号X表示在tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示为D/F的符号类型中包含上行子带,或者,该符号X表示在tdd-UL-DL-configurationCommon、 tdd-UL-DL-ConfigurationDedicated、SFI中的至少一项指示为U/F的符号类型中包含下行子带。
本公开的实施例,网络侧设备向终端发送时域配置信息,可以在目标信息指示为下行的时间单元配置上行子带或者配置上行子带并进行上行传输,在目标信息指示为上行的时间配置下行子带或者配置下行子带并进行下行接收,在目标信息指示为灵活方向的时间单元配置上行子带、下行子带、配置上行子带并进行上行传输、配置下行子带并进行下行接收。
作为一个可选实施例,所述方法还包括:接收所述网络侧设备发送的所述时域配置信息的有效时间信息;
所述根据所述时域配置信息确定时间单元的传输配置,包括:根据所述时域配置信息,确定所述时间单元在所述有效时间内的传输配置。
该实施例中,所述时域配置信息的有效时间可以通过RRC配置;或者通过DCI format 2-0指示,例如SFI索引(index)可以是时域配置信息和有效时间的联合编码。
作为一个可选实施例,所述方法还包括:在所述终端接收到网络侧设备通过RRC信令配置的SFI相关信息,且未检测到所述时域配置信息的情况下,执行第一处理。
该实施例中,在网络侧设备向终端发送了时域配置信息时,可能存在终端漏检、错检的情况,导致终端没有接收到该时域配置信息。若网络侧设备通过RRC信令为终端配置了SFI相关信息,且终端接收到所述SFI相关信息,此时终端没有检测到所述时域配置信息,则可以执行第一处理。例如:如果网络侧设备通过RRC给UE组配置了SFI相关信息,并向对应UE组发送DCI format 2-0,但是某个UE并没有检测到DCI format 2-0,则可以执行第一处理。
所述SFI相关信息可以用于通知终端网络侧设备将要发送时域配置信息,所述SFI相关信息可以包括:时域配置信息的发送通知信息(如DCI format 2-0的发送通知)、时域配置信息的发送配置信息,如DCI format 2-0的发送时间、发送位置等。
在一些实施例中,所述第一处理包括以下一项:
1)在所述时域配置信息的有效时间内不执行数据发送和数据接收;可以 通过协议约束生效时间内不进行数据接收和发送,例如UE在所述DCI format2-0对应的生效时间内不发送也不接收。
所述生效时间例如:DCI format 2-0对应的物理下行控制信道(Physical Downlink Control Channel,PDCCH)监测(monitor)周期或者时隙组合对应的持续时间(duration of a slot format combination)。
2)根据目标信息确定所述时间单元的传输方向;该情况下UE可以按照原有的传输方向确定方式确定时间单元的传输方向。例如:UE回退到旧的TDD配置(legacy TDD配置),按照tdd-UL-DL-configurationCommon、tdd-UL-DL-ConfigurationDedicated、SFI、DCI format 2-0(legacy指示内容)的任一项或者多项指示的配置确定生效时间内的传输方向。
3)根据第一时域配置信息确定所述时间单元的传输方向,所述第一时域配置信息是终端在所述时域配置信息的前一次接收到的时域配置信息;该情况下,UE可以根据在当前未检测到的时域配置信息之前的最近一次接收到的时域配置信息确定时间单元在有效时间内的传输方向。
4)默认所述时间单元在有效时间内的传输方向是第三传输方向,所述第三传输方向是上行传输或者下行接收;例如,UE默认时间单元在生效时间内的传输方向为D或者U。
5)根据指示信息确定是否执行数据发送或者数据接收。所述网络侧设备可以向终端发送指示信息,指示终端的行为。
在一些实施例中,所述根据指示信息确定是否执行数据发送或者数据接收,包括以下至少一项:
若指示信息指示第三值,则停止在第三时间单元的数据接收,所述第三时间单元是目标信息指示为下行接收的时间单元,或者,所述第三时间单元是目标信息和第一时域配置信息均指示为下行接收的时间单元;
若所述指示信息指示第四值,则停止在第四时间单元的数据发送,所述第四时间单元是所述目标信息指示为上行传输的时间单元,或者,所述第四时间单元是目标信息和第一时域配置信息均指示为上行传输的时间单元。
该实施例中,所述第三值和所述第四值不同,例如:所述第三值是1,所述第四值是0,或者,所述第三值是0,第四值是1,在此不做限定。以所 述第三值是1,所述第四值是0为例,例如:终端确定指示信息指示1,则可以认为网络侧设备用于上行传输的资源增多,例如SBFD配置从上一次的DDXXU(X代表可以在UL子带中传输上行),更新成本次的DXXXU。该情况下,UE在上次指示为DD的时间单元(即所述第三时间单元)不再进行数据接收或者发送,因为网络侧设备可能在本次的SBFD配置中,将前面的两个D更新成X。在一些实施例中,终端可以在上一次配置为XXU的时间单元上继续进行上行传输。
若终端确定指示信息指示0,可以认为网络侧设备用于下行接收的资源增多,例如SBFD配置从上一次的DDXXU(X表示可以在UL子带中传输上行),更新成本次的DDDXU,该情况下,UE在上次指示为XX的位置不再进行数据发送,因为网络侧设备可能在本次的SBFD配置中,将前面的中间的两个XX更新成D。在一些实施例中,终端在上一次配置为D的方向上继续进行数据接收。
本公开实施例可以应用于TDD系统,也可以用于频分双工(Frequency Division Duplex,FDD)系统。
本公开的实施例,终端在检测到网络侧设备配置的时域配置信息的情况下,根据时域配置信息确定时间单元是否被配置上行子带或者下行子带,或者根据时域配置信息确定时间单元的传输方向,即时间单元的传输方向是可变的,实现了对时间单元的传输方向的动态指示。
如图2所示,本公开实施例提供一种时域配置信息指示方法,应用于网络侧设备,该方法包括:
步骤201、向终端发送时域配置信息,所述时域配置信息用于指示时间单元的传输配置;
其中,所述传输配置包括以下至少一项:
所述时间单元被配置上行子带;
所述时间单元被配置下行子带;
所述时间单元的传输方向。
该实施例中,时域配置信息可以用于指示时间单元的传输方向、该时间单元是否被配置了上行或者下行子带,使终端检根据该时域配置信息确定时 间单元的传输配置,例如:确定某个时间单元是否被配置了上行子带或者下行子带,或者确定某个时间单元的传输方向。
以时域配置信息指示时间单元是否被配置上行子带或者下行子带为例,所述时间单元被配置的子带可以与时间单元的传输方向相反,例如:时域配置信息可以指示对上行时间单元配置了下行子带,终端可以在该上行时间单元进行下行接收,也可以不进行下行接收;或者,所述时域配置信息可以指示下行时间单元配置了上行子带,终端可以在该下行时间单元进行上行传输,也可以不进行上行传输。
以时域配置信息指示时间单元的传输方向为例,所述时间单元被配置的传输方向可以与该时间单元的原传输方向相反,例如:时域配置信息可以指示终端在上行时间单元进行下行接收,即在上行时间单元上的下行子带上接收下行;或者,时域配置信息可以指示终端在下行时间单元进行上行传输,即在下行时间单元上的上行子带上传输上行。
需要说明的是,本公开实施例所述的上行时间单元是通过目标信息确定为上行的时间单元,下行时间单元是通过目标信息确定为下行的时间单元。
本公开的实施例,网络侧设备向终端时域配置信息,该时域配置信息可以指示时间单元是否被配置上行子带或者下行子带,或者指示时间单元的传输方向,实现了对时间单元的传输方向的动态指示。
在一些实施例中,所述时域配置信息承载在预定DCI中;
其中,所述预定DCI包括以下至少一项:
所述时域配置信息对应的专用DCI格式;即针对所述时域配置信息设计的专用DCI格式。
DCI格式2-0,网络侧设备可以通过DCI format 2-0向终端发送时域配置信息。
在一些实施例中,所述时域配置信息指示以下一种时域范围内的时间单元的传输配置值;
1)全部时隙;所述时域配置信息可以应用于全部slot中的时间单元,即指示全部时隙内的时间单元的传输配置。
2)RRC指示的时域范围;所述时域配置信息可以应用于RRC指示的子 带全双工(sub-Band Full Duplex,SBFD)的时域范围,即指示RRC指示的SBFD时域范围内的时间单元的传输配置;或者,所述时域配置信息可以应用于RRC指示的其他时域范围,即RRC指示所述时域配置信息生效时间范围,所述时域配置信息在所述生效时间范围内的时间单元有效。
3)预定义的时域范围;所述时域配置信息可以应用于协议中预定义的时域范围,即指示预定义时域范围内的时间单元的传输配置。
4)灵活子带对应的时域范围。网络侧设备可以在某些时间单元配置灵活子带,例如在部分下行/灵活symbol上面配置上行子带,在所述时域范围内的时间单元的传输配置是灵活的,可以动态改变传输配置,因此称为灵活子带。时域配置信息仅应用于配置了灵活子带的时间单元。
作为一个可选实施例,所述时域配置信息用于指示时间单元的传输方向是第一传输方向;
所述第一传输方向与目标信息指示的所述时间单元的第二传输方向相反;或者,所述第一传输方向与目标信息指示的所述时间单元的第二传输方向相同。
该实施例中,时域配置信息可以指示时间单元的传输方向,其中,时域配置信息指示的传输方向可以与该时间单元的原传输方向相反也可能相同,即网络侧设备可以通过时域配置信息改变时间单元的传输方向。以第一传输方向与第二传输方向相反为例,例如:时间单元根据目标信息指示是上行时间单元,网络侧设备可以通过时域配置信息指示该时间单元进行下行接收,即在该时间单元的下行子带进行下行接收;或者,时间单元根据目标信息指示是下行时间单元,网络侧设备可以通过时域配置信息指示该时间单元进行上行传输,即在该时间单元的上行子带进行上行传输。
作为一个可选实施例,所述时域配置信息用于指示时间单元被配置上行子带或者指示所述时间单元被配置下行子带;
其中,若目标信息指示所述时间单元的传输方向是上行,则所述时域配置信息指示所述时间单元被配置下行子带;
若目标信息指示所述时间单元的传输方向是下行,则所述时域配置信息指示所述时间单元被配置上行子带。
该实施例中,网络侧设备通过时域配置信息指示时间单元是否被配置上行子带或者下行子带。在一些实施例中,若时间单元被配置了上行子带或者下行子带,该时间单元的传输方向可以与被配置的子带传输方向相同,也可以不同。例如:若目标信息指示时间单元的传输方向是上行,例如该时间单元是上行传输单元,网络侧设备可以通过时域配置信息指示该时间单元被配置下行子带,则终端可以在该时间单元进行下行接收(也可以不进行下行接收);或者,若目标信息指示时间单元的传输方向是下行,例如该时间单元是上行时间单元,网络侧设备可以通过时域配置信息指示该时间单元被配置上行子带,则终端可以在该时间单元进行上行传输(也可以不进行上行传输)。

以第一值是0、第二值是1、时间单元是符号为例,若网络侧设备指示某个符号对应的数值是0,表示根据目标信息确定该符号的传输方向,即在该符号上面无子带,UE根据被配置和/或接收到的目标信息确定这个符号的传输方向是D,或者是U,或者是灵活方向。
若网络侧设备指示某个符号对应的数值是1,表示该符号被配置了上行子带或者下行子带,或者表示该符号被配置了上行子带或下行子带,且该符号的传输方向是上行或下行,或者表示该符号的传输配置根据子带全双工的配置信息确定。其中,所述符号被配置的是上行子带还是下行子带,可以根据该目标信息指示的该符号的传输方向确定。

所述第一符号可以是预定义的,与指示上行的符号(如U)、指示下行的符号(如D)以及指示灵活方向的符号(如F)均不同的符号。若网络侧设备配置某个第二时间单元对应的符号是第一符号,则表示该第二时间单元被配置上行子带或者下行子带,或所述时间单元被配置上行子带或者下行子带且所述时间单元的传输方向为上行或者下行,或者表示该第二时间单元的传输配置根据子带全双工的配置信息确定。
