背景技术
基于长期演进(Long Term Evolution,LTE)的授权辅助接入(Licensed-Assisted Access)(LAA-LTE)系统中,以授权频谱上的载波为主载波,以免授权频谱上的载波为辅载波为终端设备提供服务,其中,在免授权频谱上,通信设备遵循“先听后说(Listen Before Talk,LBT)”原则,即通信设备在免授权频谱的信道上进行信号发送前,需要先进行信道侦听,只有当信道侦听结果为信道空闲时,该通信设备才能进行信号发送;如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙,该通信设备不能进行信号发送。
由于通信设备的传输是机会性的,只有LBT成功才能进行数据传输,LBT失败时不能进行数据传输,因此,网络设备以及在该网络设备服务的小区中的终端设备需要明确对方什么时候开始进行数据传输,什么时候停止数据传输,从而实现终端设备和网络设备之间正确的数据通信。
将新无线(New Radio,NR)技术应用到免授权频谱上时,支持多种子载波间隔以及大带宽传输,此情况下,如何判断进行数据传输的资源位置以实现终端设备与网络设备之间的正常的数据通信是一项亟需解决的问题。

此外,图2至图4中的各个步骤可以分别按照与图2至图4所呈现的不同的顺序来执行,并且有可能并非要执行图2至图4中的全部操作。
图2是根据本申请实施例的传输信息的方法的示意性流程图,如图2所示,该方法200包括如下内容:
S210,网络设备确定第一载波上能够使用的第一时域资源,该第一时域资源为第一下行传输机会中的时域资源;
S220,该网络设备通过该第一载波上的该第一时域资源向终端设备发送第一信息,其中,该第一信息用于指示根据第一子载波间隔确定第一传输机会的时域资源信息。
因此,网络设备可以通过第一载波上的第一传输机会中的时域资源,向终端设备发送第一信息,通过该第一信息指示第一传输机会(例如,可以包括上行传输机会和/或下行传输机会)的时域资源信息的确定方式,从而,该终端设备和该网络设备对于第一传输机会的时域资源位置达成共识,能够实现终端设备和网络设备之间的正确的数据通信。
需要说明的是,在本申请实施例中,该第一载波为免授权载波,即该第一信息可以用于指示免授权载波上的传输机会的时域资源信息的确定方式。
可选地,在本申请实施例中,用于发送该第一信息的该第一时域资源可以是该第一 下行传输机会中网络设备配置的用于传输下行控制信道的时域资源,例如,控制资源集(Control Resource Set,CORESET)中的时域资源。
应理解,在本申请实施例中,一次下行传输机会可以定义为网络设备连续传输的时间单元,同理,一次上行传输机会可以定义为终端设备连续传输的时间单元。一个时间单元可以定义为一个或多个子帧,也可以定义为一个或多个时隙,还可以定义为一个或多个微时隙或符号等。一次下行传输机会或一次上行传输机会的起始时间单元和/或结束时间单元可以是完整的时间单元,也可以是部分时间单元等,本申请实施例对此不作限定。

或者,该第一传输机会的时域资源信息可以包括第一传输机会的结束位置,例如,结束符号,或结束时隙等。
或者,该第一传输机会的时域资源信息可以包括第一传输机会的信道占用的时间长度,即在该第一传输机会上进行信道传输所占用的时间长度,例如,子帧个数或时隙个数等。
或者,该第一传输机会的时域资源信息可以包括该第一传输机会的时隙结构,例如,该第一传输机会的时隙结构可以采用位图方式指示一个或多个时隙内的时隙结构,或者该第一传输机会的时隙结构也可以指示一个时隙内包括的下行符号的个数信息和/或上行符号的个数信息,或者该第一传输机会的时隙结构可以指示一个时隙内的时隙结构索引,该时隙结构索引可以用于指示特定的时隙结构,本申请实施例不特别限定该第一传输机会的时隙结构的指示方式。
可选地,在本申请实施例中,该第一传输机会可以包括该第一载波上的该第一下行传输机会和/或该第一载波上的第一上行传输机会,即该网络设备不仅可以通过该第一信息指示该第一载波上的下行传输机会的时域资源信息,还可以通过该第一信息指示该第一载波上的上行传输机会的时域资源信息,这样,该终端设备和该网络设备对于该第一载波上的下行传输机会和/或上行传输机会的时域资源位置可以达成共识,从而能够实现终端设备和网络设备之间的正确的数据通信。
可选地,在一些实施例中,该第一载波上的该第一上行传输机会所在的频域资源和该第一载波上的该第一下行传输机会所在的频域资源至少有部分重叠,例如,该第一载波上的该第一下行传输机会和该第一载波上的该第一上行传输机会可以位于该第一载波上的同一子频带上。
应理解,在本申请实施例中,用于确定该第一传输机会的时域资源信息的该第一子载波间隔可以是通信系统定义的子载波间隔,或者,该第一子载波间隔可以是网络设备配置的子载波间隔,或者,该第一子载波间隔也可以是网络设备传输下行控制信息所使用的子载波间隔等,本申请实施例对此不作限定。
可选地,该第一子载波间隔的大小小于或等于该第一载波上用于物理信道传输的子载波间隔的大小。
以下,详细说明该第一信息的指示方式。
实施例1:该第一信息还可以用于指示根据该第一子载波间隔确定第二传输机会的时域资源信息,其中,该第二传输机会包括以下情况中的至少一个:

第二载波上的第三下行传输机会;
第二载波上的第三上行传输机会;
其中,该第二传输机会所在的频域资源和该第一传输机会所在的频域资源不重叠。
也就是说,该第一信息不仅可以指示根据该第一子载波间隔确定该第一传输机会的时域资源信息,还可以用于指示根据该第一子载波间隔确定第二传输机会的时域资源信息,即该网络设备可以指示根据同一子载波间隔确定第一传输机会和第二传输机会的时域资源信息,根据该第一传输机会和该第二传输机会所处的频域位置,可以包括如下两个场景。
场景1:该第一传输机会和该第二传输机会可以位于同一个载波的不同的子频带上,例如,该第一载波可以包括第一子频带和第二子频带,该第一传输机会可以位于该第一载波的第一子频带上,该第二传输机会可以位于该第一载波的第二子频带上,具体的说,该第一传输机会可以包括该第一载波的第一子频带上的第一上行传输机会和/或第一下行传输机会,该第二传输机会可以包括该第一载波的第二子频带上的第二上行传输机会和/或第二下行传输机会。
场景2:该第一传输机会和该第二传输机会可以位于不同的载波上,例如,该第一传输机会位于该第一载波上,该第二传输机会位于第二载波上,该第一传输机会可以包括第一载波上的第一上行传输机会和/或第一下行传输机会,该第二传输机会可以包括第二载波上的第三下行传输机会和/或第三上行传输机会。可选地,该第二载波上的该第三下行传输机会和该第二载波上的该第三上行传输机会可以位于该第二载波的同一子频带上。

或者,在该第一载波上传输的该第一信息可以用于指示根据不同的子载波间隔确定不同载波上的传输机会的时域资源信息,即场景4,其中,该不同载波上的传输机会的时域资源位置也可以不同,例如,网络设备在不同的载波上可以有不同的下行传输机会的结束位置,从而在网络设备的负载变少时,网络设备可以释放空闲的频域资源,从而能够提升频域资源的利用率。
可选地,在该实施例2的一个具体实施例中,该第一信息用于指示根据该第一子载波间隔确定该第一传输机会的第一结束位置,该第一信息还用于指示根据该第二子载波间隔确定该第三传输机会的第三结束位置,该第一结束位置和该第三结束位置之间的距离小于或等于第二预设值。

可选地,在一些实施例中,该方法200还可以包括:
该网络设备根据第三子载波间隔传输下行物理信道。
其中,该第三子载波间隔和该第一子载波间隔可以不同,即用于传输下行物理信道的子载波间隔和用于确定下行传输机会的子载波间隔可以不同,也就是说,根据第一子载波间隔确定下行传输机会上的时域资源信息后,实际进行数据传输时,可以根据与所述第一子载波间隔不同的第三子载波间隔传输下行物理信道,当然,该网络设备也可以根据第一子载波间隔传输下行物理信道,本申请实施例对此不作具体限定。

再例如,如图4所示,该第一载波可以包括子频带#1和子频带#2,该第一信息可以用于指示根据第一子载波间隔(例如15kHz)确定子频带#1对应的第一下传输机会的时域资源信息,还可以用于指示根据第二子载波间隔(例如30kHz)确定子频带#2对应的第二下行传输机会的时域资源信息,其中,子频带#1和子频带#2上的下行传输机会的结束位置可以不同,可选地,结束位置的时间差可以小于或等于第二预设值。
在子频带#1和子频带#2实际进行数据传输时,网络设备可以在子频带上信道检测成功(例如LBT成功,或CCA成功)后,根据和第一子载波间隔相同或不同的子载波间隔在子频带#1上传输下行物理信道(例如,在子频带#1上的第一下行传输机会的时域资源上,可以根据15kHz,30kHz和60kHz中的一种或多种子载波间隔传输下行物理信道),根据和第二子载波间隔相同或不同的子载波间隔在子频带#2上传输下行物理信道(例如,在子频带#2上的第二下行传输机会的时域资源上,也可以根据15kHz,30kHz和60kHz中的一种或多种子载波间隔传输下行物理信道)。
可选地,在一些实施例中,S220可以具体包括:
该网络设备根据该第一子载波间隔通过所述第一载波上的所述第一时域资源向终端设备发送第一信息;或者,
该网络设备根据第四子载波间隔通过所述第一载波上的所述第一时域资源向终端设备发送第一信息。
其中,该第一子载波间隔和该第四子载波间隔不同,也就是说,该用于发送该第一信息的子载波间隔和用于确定下行传输机会的子载波间隔可以相同,也可以不同。具体的,网络设备可以确定用于发送该第一信息的下行控制资源,该下行控制资源可以是根据第一子载波间隔确定的,或者也可以是根据其他子载波间隔确定的,本申请实施例对此不作限定,其中,该下行控制资源为前述的第一时域资源,进一步地,该网络设备可以根据给第一子载波间隔或非第一子载波间隔例如第四子载波间隔在该第一载波上的该下行控制资源上发送该第一信息。
