Description

一种信息传输方法和装置

技术领域
本申请涉及无线通信技术,尤其涉及一种信息传输方法和装置。
背景技术
在基于非授权频谱部署的通信系统中,各节点通过非授权频谱上的接收功率的大小来判断其忙闲状态,如果接收功率小于一定门限,则认为非授权频谱上没有干扰源且处于空闲状态,那么就可以在非授权频谱上发送信号,这种先监听后发送的机制被称作先听后说(listen before talk,LBT),能够避免各节点之间在使用非授权频谱资源时的冲突。由于各节点是通过竞争的方式来使用/共享无线资源,所以会导致非授权频谱上的传输起始时刻不固定,且每次传输所占用的频域信道宽度也随着信道空闲评估结果的不同而变化,同时一次传输的最大信道占用时长也受到限制,并且无法向各节点动态的指示每次的信道占用时长。
目前,在无线保真技术(Wi-Fi)系统中,在每个数据包包头中携带包含传输机会(transmit opportunity,TXOP)的控制信息,该TXOP用于指示本数据包传输所用的带宽、本数据包传输的时长以及本数据包结束之后的剩余TXOP时长。虽然剩余TXOP时长可以动态的更新指示,但无法动态指示剩余信道占用时长内的子帧上下行配置,终端仍然需要持续监听控制信息而消耗电量,造成能量损失。

本申请实施例提供了一种信息传输方法和装置,可以动态指示时间单元在传输方向上的时域结构配置,以使得终端提前获知上述时域结构配置,进而无需持续监听控制信息,节约能量。除上述动态指示传输方向上的时域结构配置(即时间单元的格式配置)之外,终端还可以基于网络设备指示的格式配置,以及终端周边的信息(例如周边其他终端的数据收发信息)确定上述网络设备指示的格式配置中的哪些时间单元是可用的,哪些时间单元是不可用的,进而,终端生成反馈信息,并向网络设备反馈可用的时间单元,从而使得网络设备可以根据终端的反馈信息进行数据传输调度,并减少误调度,提高数据传输效率。下面先对本发明实施例可能涉及的一些术语进行简单介绍。
LBT:是一种避免各节点之间在使用非授权频谱资源时的冲突的机制,具体来说,由于在非授权频谱上部署的通信系统通常基于竞争的方式来使用/共享无线资源,所以下辖的各节点在发送信号之前,首先会监听非授权频谱是否空闲,比如通过非授权频谱上的接收功率的大小来判断其忙闲状态,如果接收功率小于一定门限,则认为非授权频谱上没有干扰源且处于空闲状态,则可以在该非授权频谱上发送信号,否则不发送信号。
最大信道占用时长(maximum channel occupancy time,MCOT):表示一次传输过程的信道占用时长(channel occupancy time,COT)的最大值。MCOT的大小受限于所传输数据的业务类型以及所占用的非授权频谱的使用法规。

上述entry index也可以不被显性配置,隐性包含于Format X_n的通知信令中。例如按顺序依次配置了格式配置1,格式配置2,…,因此UE收到时可以缺省的认为格式配置1对应的就是entry index 1,格式配置2对应的就是entry index 2,…。
可选的,在一种实施方式中,第一指示信息可以包括第一时长内时间单元的格式配置 的标识,其中,该第一时长内时间单元的格式配置的标识与第一时长内时间单元的格式配置之间的对应关系可以包括但不限于如表1所示的对应关系。
可选的,在一种实施方式中,网络设备101向终端102发送第一指示信息,具体可以是:网络设备101在预设频率资源上向终端102发送上述第一指示信息。其中,网络设备101配置给终端102控制资源集(control resource set,CORSET)用于发送第一指示信息。所述预设频率资源可以是网络设备101预先配置给终端的控制资源集,相应的,终端102在该网络设备101配置给终端102的控制资源集上进行检测,获取第一指示信息。第一指示信息还可以被发送在对应的搜索空间上,所述搜索空间也是网络设备101预先配置给终端102的组共同的搜索空间(group common search space,或称为组公共搜索空间)。如上所述,全文所述所有配置,或预先配置,均可以为通过RRC信令,MAC信令和者物理层(PHY)信令中的至少一种进行发送。

一、反馈信息中包括指示位和至少一个时间段
图2为本申请实施例提供的信息传输方法的一个实施例示意图。
可选的,201、gNb生成第一指示信息。
其中,第一指示信息用于指示第一时长内时间单元的格式配置,该格式配置是上下行传输方向的配置,该格式配置包括上行传输方向、下行传输方向和未知传输方向中的一种或者多种的配置。
可选的,在一种实施方式中,第一指示信息具体可以为第一时长内时间单元的格式配置的标识。其中,在UE接收到上述第一时长内时间单元的格式配置的标识之后,UE可以根据gNb在发送第一指示信息之前发送的对应关系信息,该对应关系信息包括但不限于上述表1中所述的对应关系,UE基于gNb通过RRC信令,MAC信令和者物理层信令中的至少 一种信令下发的对应关系信息和上述第一时长内时间单元的格式配置的标识确定第一指示信息指示的格式配置;或者,UE预先存储上述如表1所示的对应关系信息,在UE接收到gNb下发的携带于第一指示信息中的上述第一时长内时间单元的格式配置的标识之后,UE在表1中查询上述第一时长内时间单元的格式配置的标识,以得到第一指示信息指示的格式配置。
可选的,第一指示信息可以是指示一个或者多个子帧(subframe)、迷你子帧(mini-subframe)、时隙(slot)、迷你时隙(mini-slot)和OFDM符号中任一种时间单元的一个或者多个项entry指示的联合指示。示例性的,当上述Format X_n中包括一个或者多个subframe时,每一个subframe对应一个entry指示指示每一个subframe的具体格式配置,第一指示信息是包括一个或者多个subframe的entry指示的联合指示信息;
或者,当上述Format X_n中包括一个或者多个mini-subframe时,每一个mini-subframe对应一个entry指示指示每一个mini-subframe的具体格式配置,则第一指示信息是包括一个或者多个mini-subframe的entry指示的联合指示信息;
或者,当上述Format X_n中包括一个或者多个slot时,每一个slot对应一个entry指示指示每一个slot的具体格式配置,则第一指示信息是包括一个或者多个slot的entry指示的联合指示信息;
或者,当上述Format X_n中包括一个或者多个mini-slot时,每一个mini-slot对应一个entry指示指示每一个mini-slot的具体格式配置,则第一指示信息是包括一个或者多个mini-slot的entry指示的联合指示信息,其中,mini-slot中可以包括1个OFDM符号,2个OFDM符号,4个OFDM符号或者7个OFDM符号;
或者,当上述Format X_n中包括一个或者多个OFDM符号时,每一个OFDM符号对应一个entry指示指示每一个OFDM符号的具体格式配置,则第一指示信息是包括一个或者多个OFDM符号的entry指示的联合指示信息;
或者,当上述Format X_n中包括多个OFDM符号时,Format X_n中的多个OFDM符号对应一个entry指示指示多个OFDM符号的具体格式配置,则第一指示信息可以是包括一个或者多个entry指示的联合指示信息。
可选地,第一指示信息可以是指示可以是subframe、mini-subframe、slot、mini-slot和OFDM符号至少两种粒度的时间单元的时隙组合slot combination对应的多个entry指示的联合指示。可以理解,当Format X_n包括上述至少两种粒度的时间单元时,基于上述Format X_n包括的粒度划分各自粒度对应的entry指示,例如,上述Format X_n中包括多个slot、多个mini-slot和多个OFDM符号,那么第一指示信息中包括上述多个slot对应的多个entry指示、多个mini-slot对应的多个entry指示以及多个OFDM符号对应的多个entry指示。需要说明的是,关于第一指示信息的其他描述可参阅上述表1的相关描述,此处不再赘述。
可选的,上述第一指示信息具体可以是时隙格式指示(slot format indicator,SFI)信息,或者其他时间单元的格式配置的指示信息。
202、gNb在非授权频谱上向UE发送第一指示信息。
可选的,在一种实施例中,gNb可以将该第一指示信息通过无线资源控制(radio resource control,RRC)信令,媒介访问控制(media access control,MAC)信令,以及物理层信令中的至少一种信令配置给UE。可选的,在一种实施例中,gNb可以将该第一指示信息通过物理下行控制信道(physical downlink control channel,PDCCH)进行发送,并且,通过PDCCH发送第一指示信息可以通过组共同的group common PDCCH进行发送,具体地,可以是将第一指示信息承载于一种在PDCCH中新定义的专门用于时间单元配置通知的格式的下行控制信息(downlink control index,DCI)格式,例如,上述新定义的格式可以是SFI-DCI格式。
其中,第一指示信息是一种动态指示,该动态指示可以是以监听周期的方式被获取,换言之,在从LBT成功,gNb可以使用信道的持续期间内,gNb可以根据监听周期,监听偏移量,以及监听符号中的一个或者多个,确定监听时刻,并且,gNb在该监听时刻向UE发送上述第一指示信息的动态指示。该第一指示信息的动态指示中包含的第一时长的时间单元的时域结构配置信息,上述第一时长都小于或等于信道占用时间。所述信道占用时间可以是最大信道占用时间,或者,是小于最大信道占用时间的另一信道占用时间。其中,第一时长可以是一个变化的值,一方面,第一时长可以大于或等于监听周期,这时从某监听时刻获取到的动态指示可以指示与监听周期相比更长时间内的时间单元的时域结构配置信息;另一方面,当监听时刻到最大信道占用时间的结束时刻之间的时间长度小于监听周期时,这时第一指示信息指示的第一时长小于监听周期,从而使得接近最大信道占用时间的终止时刻时,能指示对应的时间长度的格式配置,所述对应的时间长度指从该监听时刻到最大信道占用时间的终止时刻之间的时间长度。可以理解的是,为了使得UE能根据监听周期,监听偏移量,以及监听符号中的一个或者多个,确定监听时刻,因此,gNb可以配置并发送给UE监听周期,监听偏移量,监听符号中的一个或者多个。
从上述以动态指示的形式发送第一指示信息的技术方案中可知,当监听时刻正好落于上述动态指示DCI所指示的上行传输方向的时间单元导致所述第一指示信息无法发送时,由于第一时长可以大于或者等于监听周期时,仍然可以通过之前监听时刻发送的第一指示信息去获取对应的时间单元的配置。
可选的,在一种实施方式中,第一指示信息是由预设标识得到的。其中,该预设标识可以是下行链路DL组特定的无线网络临时标识(radio network tempory identity,RNTI),或者组共同的group common RNTI。
可选的,在一种实施方式中,上述第一指示信息还可以被包含于随机接入响应消息message 2中,或者被包含于信道占用指示PDCCH(channel utilization indication/indicator PDCC,CUI-PDCCH)中发送至UE。
可选的,如果gNb将最大信道占用时间分成准备阶段和数据传输阶段,则gNb将第一指示信息在数据准备阶段发送至UE。
可选的,在一种实施方式中,gNb可以使用配置给UE的CORSET上的预设频率资源上向UE发送第一指示信息。或者,第一信息还可以在UE的组共同的搜索空间group common search space上发送至UE。
可选的,203、UE根据第一指示信息指示的格式配置和信道检测结果生成反馈信息。
反馈信息是UE对周边网络设备以及其他UE干扰进行检测之后,基于干扰检测结果将第一指示信息指示的时间单元中的没有被干扰或者干扰低于预设阈值的时间单元确定为可用的时间单元,并将该可用的时间单元生成反馈信息,该反馈信息中包括用于指示上述可用的时间单元和不可用的时间单元中的至少一项。
具体地,在UE确定gNb通过第一指示信息下发的格式配置之后,UE根据进行信道检测得到确定周边其他UE以及其他网络设备占用的时间单元/时间段,进而,UE将其他UE或者网络设备占用的时间单元/时间段与第一指示信息指示的时间单元/时间段的重合部分确定为不可用的时间单元/时间段,将其余非重合部分确定为可用的时间单元/时间段。
其中,UE根据该第一时长内时间单元的格式配置的标识确定该第一时长内时间单元的格式配置,其具体确定方法可以是但不限于以下两种实现方式:
1)第一时长内时间单元的格式配置由UE基于gNb下发至终端的对应关系表(例如上述表1)确定,如表1所示为上述标识与第一时长内时间单元的格式配置之间的对应关系,上述对应关系表是在gNb下发第一时长内时间单元的格式配置之前发送给UE的。
2)UE预先存储上述对应关系表并基于上述对应关系表,在UE接收到gNb下发的第一时长内时间单元的格式配置的标识之后,UE使用接收到的格式配置的标识在上述对应关系表中进行查询得到第一时长内时间单元的格式配置。
可选的,204、UE在非授权频谱上发送反馈信息,该反馈信息中包括指示位和至少一个时间段。
其中,指示位用于指示反馈信息中至少一个时间段中第一个时间段是可用的或者不可用的,当至少一个时间段为两个或者两个以上时间段时,以N个时间段为例,N为大于2的正整数,若指示位指示第一个时间段是可用的,则至少一个时间段中的第一个时间段是可用的,第二个时间段是不可用的,……,第(N-1)个时间段是可用的,第N个时间段是不可用的其中,N为偶数;或者,若指示位指示第一个时间段是可用的,则至少一个时间段中的第一个时间段是可用的,第二个时间段是不可用的,……,第(N-1)个时间段是不可用的,第N个时间段是可用的,其中,N为奇数;或者,若指示位指示第一个时间段是不可用的,则至少一个时间段中的第一个时间段是不可用的,第二个时间段是可用的,……,第(N-1)个时间段是不可用的,第N个时间段是可用的,其中,N为偶数;或者,若指示位指示第一个时间段是可用的,则至少一个时间段中的第一个时间段是可用的,第二个时间段是不可用的,……,第(N-1)个时间段是可用的,第N个时间段是不可用的,其中,N为奇数。
可选的,该反馈信息中包括的指示位可以被省略,即,该反馈信息可以不包含该指示位,只包含至少一个时间段。例如,如果缺省地规定或默认,该反馈信息总是从可用的时间段开始进行反馈,则,该指示位可以被省略。
需要注意的是,本申请实施例中的反馈信息可以不依赖于本申请实施例中的指示信息指示的格式配置。
可选的,在一种实施方式中,反馈信息可以承载于一种新定义的上行控制信息(uplink  control index,UCI)格式中发送。其中UCI格式的反馈信息是一种专门用于UE向gNb反馈可用的时间单元的上报格式,该格式可以称之为SFI-UCI。可以理解的是,该SFI-UCI格式的反馈信息可专用于反馈gNb通过SFI-DCI格式下发送的第一指示信息。
可选的,在一种实施方式中,UE在非授权频谱上的预设频域资源上发送上述反馈信息,其中,该反馈信息是由预设标识进行加扰后得到的,该预设标识可以是上行链路UL组共同的group common的RNTI,该UL组共同的group common RNTI是gNb通过高层信令配置的。预设频域资源也是gNb通过高层信令配置用于UE发送反馈信息的频率资源。这部分资源可以是一个网络设备配置的特定的搜索空间。
可选的,205、gNb根据UE反馈的指示位和至少一个时间段对UE进行数据传输调度。
gNb根据UE反馈的指示位和至少一个时间段对UE进行数据传输调度可以是gNb根据UE通过指示位和至少一个时间段反馈的可用的时间段进行调度,也可以是gNb同时对指示位和至少一个时间段反馈的可用的时间段和不可用的时间段进行调度。具体的,一方面,gNb在根据指示位和至少一个时间段得到的可用的时间段上进行调制解调方案(modulation and coding scheme,MCS)不受限的调度方式进行数据调度,所述MCS不受限的调度方式为预设的允许调度MCS的调度方式,可选的,另一方面,gNb指示位和至少一个时间段指示的不可用的时间段上进行MCS受限的调度方式进行数据调度,所述MCS受限的调度方式MCS低于预设的允许调度MCS的调度方式,例如,所述MCS受限的调度方式MCS具体可以是正交相移键控(quadrature phase shift keying,QPSK),正交振幅调制(quadrature amplitude modulation,QAM)如16QAM等较小的调制解调方案。
可以理解的是,在UE反馈的可用的时间段大于或者等于待调度数据所需的时域资源的情况下,gNb只使用UE反馈的可用的时间段进行数据调度,而不使用UE反馈的不可用的时间段进行数据调度。类似的,在UE反馈的可用的时间段小于待调度数据所需的时域资源的情况下,可以改变调度方式进行数据调度,以使得时域资源够用,或者,也可以使用部分或者全部的UE反馈的不可用的时间单元进行数据调度。
二、反馈信息中包括UE确定的时间单元的指示信息或者UE确定的时长的指示信息;

可选的,301、gNb生成第一指示信息。
302、gNb在非授权频谱上向UE发送第一指示信息。
可选的,303、UE根据第一指示信息指示的格式配置和信道检测结果生成反馈信息。
上述步骤301至步骤303分别与上述步骤201至步骤203类似,此处不再赘述。
可选的,304、UE在非授权频谱上发送反馈信息,该反馈信息中包括UE确定的时间单元的指示信息或者UE确定的时长的指示信息。
与以上实施例中反馈信息的反馈方式或者指示方式不同,本实施例中UE反馈的反馈信息是通过UE确定的时间单元的指示信息,或者,UE确定的时长的指示信息来指示UE可用的时间单元/时间段。可选的,作为一种实施例方式,所述UE确定的时间单元的指示信息可以为UE确定可用的时间单元的标识或者不可用的时间单元的标识。其中,UE确定可用 的时间单元的标识或者不可用的时间单元的标识对应的格式配置可以与第一指示信息指示的格式配置中的部分配置相同、全部配置相同。可以理解的是,UE确定可用的时间单元的标识可以反馈的粒度比第一指示信息指示的粒度更小的时间单元,例如,第一指示信息中指示的某个slot中包括7个OFDM符号,其中,UE检测到该slot中的4个OFDM符号可用,另外3个OFDM符号不可用。
可选的,UE确定的时长的指示信息可以是该时长对应的起始时刻以及持续时长,或者其他表示时间段的其他指示方式,对此本申请不做任何限制。
可选的,在一种实施方式中,反馈信息可以承载于一种新定义的UCI格式中发送。其中UCI格式的反馈信息是一种专门用于UE向gNb反馈可用的时间单元的上报格式,该格式可以称之为SFI-UCI。可以理解的是,该SFI-UCI格式的反馈信息可专用于反馈gNb通过SFI-DCI格式下发送的第一指示信息。
可选的,在一种实施方式中,UE在非授权频谱上的预设频域资源上发送上述反馈信息,其中,该反馈信息是由预设标识进行加扰后得到的,该预设标识可以是上行链路UL组共同的group common的RNTI,该UL组共同的group common RNTI是gNb通过高层信令配置的。预设频域资源也是gNb通过高层信令配置用于UE发送反馈信息的频率资源。这部分资源可以是一个网络设备配置的特定的搜索空间。
可选的,305、gNb根据UE反馈的UE确定的时间单元的指示信息或者UE确定的时长的指示信息对UE进行数据传输调度。
此步骤305与上述步骤205类似,步骤305的描述可参阅上述步骤205中的相关描述,对此此处不再赘述。

上述步骤401至步骤403分别与上述步骤201至步骤203类似,此处不再赘述。
可选的,404、UE在非授权频谱上发送反馈信息,该反馈信息中包括第一位图。

此步骤605的其他相关描述与上述步骤205中的描述类似,步骤605的描述可参阅上述步骤205中的相关描述,对此此处不再赘述。
其中,上述图1对应的方法实施例涉及的各步骤的所有相关内容均可以援引到,但不限于图2至图6中gNb和UE的功能描述,在此不再赘述。
在上述图2至图6对应的实施例中,UE接收到gNb在非授权频谱上发送的第一指示信息指示的格式配置之后,UE基于上述第一指示信息指示的格式配置确定UE可用的时间单元,进一步生成相应的反馈信息,并且UE在非授权频谱上将该反馈信息反馈至gNb,使得gNb可以基于上述反馈信息中UE可用的时间单元对终端进行数据传输调度,从而减少在5G移动通信系统中非授权频谱段上gNb的误调度,提高非授权频谱段上的数据传输效率。
在上述图2至图6所述的实施例中,在步骤205、步骤305、步骤405、步骤505和步骤605中的gNb根据UE反馈的反馈信息对UE进行数据传输调度中,根据反馈信息中的时间单元与第一指示信息指示的格式配置对应的时间单元,其具体的调度方式具体可以包括以下两种数据调度方式:
第一种数据调度方式为:当第一指示信息指示的第一时长内的时间单元的格式配置,与反馈信息中UE可用的时间单元对应的格式配置之间的交集大于预设阈值时,在gNb接收到UE的反馈信息之后,gNb根据反馈信息中UE可用的时间单元对应的格式配置对UE进行数据传输调度。可以理解的是,此种情况下,UE受到周边其他UE的信号干扰较小,gNb可以直接根据UE反馈的UE可用的时间单元进行数据调度。也说明第一指示信息中包含的格式配置对于UE来说比较适用。那么,当UE受到周边其他UE的信号干扰较大时,gNb将采用下述的第二种数据调度方式进行数据调度。
第二种数据调度方式为:当第一指示信息指示的第一时长内的时间单元的格式配置,与反馈信息中UE可用的时间单元对应的格式配置之间的交集小于预设阈值时,这样的情形发生在一个UE或者多个UE的反馈中,在gNb接收到UE的反馈信息之后,gNb向UE下发第二指示信息,该第二指示信息用于指示第三时长内时间单元的格式配置,具体的,第三指示信息可以是第三时长内时间单元的格式配置的标识,其中,第三时长小于第二时长。上述第二指示信息的发送时间为第二时长的起始时刻,即gNb的最大信道占用时长的起始时刻,或者在上述gNb的最大信道占用时长的起始时刻之前。可选的,如果gNb将最大信道占用时间分成准备阶段和数据传输阶段,那么第二指示信息的发送时间为数据传输阶段的起始时刻,或者在准备阶段。第一指示信息发送于准备阶段。第二指示信息晚于第一指示信息的发送时刻。可选的,上述第三时长内时间单元的格式配置可以是gNb根据第一时长内的时间单元的格式配置和UE可用的时间单元的格式配置确定的。
其中,上述第二指示信息可以理解为是对第一指示信息的更新,顾名思义,第二指示信息指示的是一种新的格式配置,不同于第一指示信息指示的格式配置。具体的,第二指示信息对第一指示信息的更新可以是:基于终端反馈的可用的时间单元在粒度上的更新,例如采用粒度小于第一指示信息指示的时间单元进行调度,或者,第二指示信息对第一指示信息的更新也可以是:重新指示终端在新的时间单元/时间段上的格式配置,以为终端重新分配其他时域资源进行调度。
以上述表1中的格式配置为例来说,例如第一指示信息中携带的标识为:entry index=0,指示格式配置1:Y1个下行迷你时隙,Q1个未知方向的OFDM符号,Y2个上行迷你时隙,为了方便令Y1为2,Q1为0,Y2为2,并且,迷你时序中包括4个连续的OFDM符号,即第一指示信息指示的格式配置为:2个下行迷你时隙,2个上行迷你时隙,第二指示信息中携带有2个下行迷你时隙的索引和2个上行迷你时隙的索引;其中,终端反馈信息中指示第一指示信息指示:上述2个下行迷你时隙和2个下行迷你时隙中均是第一个迷你时隙中第三个和第四个OFDM符号可用,第二个迷你时隙中第一个和第二个OFDM符号可用,其余OFDM符号都不可用。此种情况下,则网络设备使用第二指示信息指示更小粒度的时间单元对第一指示信息进行更新,具体的,第二指示信息指示的格式配置可以是:4个下行OFDM符号,4个下行OFDM符号,其中,第二指示信息中包括:所述4个下行OFDM符号的索引和4个下行OFDM符号的索引。
需要说明的是,本申请中所述的项索引(entry index)、标识和项(entry)的含义相同,可以相互替换,或者,可以替换为其他类似的称谓,对此本申请不做任何限制。
可选的,在一种实施方式中,第二指示信息中可以包括第三时长内时间单元的格式配置的标识,其中,该第三时长内时间单元的格式配置的标识与上述第一时长内时间单元的格式配置的标识类似,此处不再赘述。
其中,上述第二指示信息与第一指示信息类似,关于第一指示信息的其他描述可参见上述步骤203中第一指示信息的相关描述,对此此处不再赘述。
在以上实施例中,通过gNb向UE在数据准备阶段第一指示信息指示在传输方向上的时域结构配置或者说SFI格式配置,并且,UE根据gNb下发的时域结构配置或者说SFI格式配置确定可用的时间单元/时间段,以使得终端提前预知了数据传输阶段的时域资源,进而使得UE不需要在时域资源上进行持续的监听导致浪费能量,达到UE节能的目的。
进一步的,gNb在获知UE上报的可用的时间单元之后,gNb可以根据UE反馈的可用的可用的时域资源进行合理调度,避免误调度,降低其他UE,以及其他网络设备的信号干扰。
需要说明的是,本申请所有实施例中各个通信设备之间的消息名字或消息中个参数的名字只是一个示例,具体实现中也可以是其他的名字,比如更新消息还可以称之为指示消息,标识也可以称之为索引,检测也可以称之为测量,在此进行统一说明,本申请实施例对此不作具体限定。
为了便于理解本申请实施例中的信息传输方法,下面结合一个具体的应用场景图对本申请实施例中的信息传输方法进行详细说明。
图7为本申请实施例提供的UE之间相互干扰的一个场景示意图。
如图7所示包括:gNb1、gNb2、gNb3、UE1、UE2和UE3,其中,gNb1是为UE1提供网络服务的基站,gNb2是为UE2提供网络服务的基站,gNb3是为UE3提供网络服务的基站,UE1既在UE2的覆盖范围内,也在UE3的覆盖范围内,换言之,UE1会同时受到UE2和UE3的干扰。
图8为本申请实施例提供的UE之间相互干扰的一个SFI指示示意图。
如图8所示,加粗实线箭头表示gNb指示UE的发送数据的COT,加粗虚线箭头表示gNb指示UE的接收数据的COT,UE2的正常实线箭头表示UE2根据信道检测结果和gNb2指示的SFI确定的UE2可用于上行传输的时间段(即图8中的时间段5所示),UE3的正常实线箭头表示UE3根据信道检测以及gNb3指示的SFI确定的UE3可用于下行传输的时间段(即图8中的时间段6所示)。gNb1向UE1下发SFI指示,该SFI指示UE1在两个连续的时间段1和时间段2上进行下行数据传输,在两个连续的时间段3和时间段4上进行上行数据传输,但是由于UE1同时受到UE2和UE3的干扰,UE2要在时间段5上进行上行数据传输对UE1在时间段1进行下行数据传输造成干扰,导致时间段1不可用;UE3要在时间段6进行下行数据传输对UE1在时间段3上进行上行数据传输造成干扰,导致时间段3不可用,因此,UE1最终将gNb1下发的SFI指示中的时间段2和时间段4确定为UE1可用的时间段,并生成相应的反馈信息上报至gNb1。
