具体地,在非授权频谱上存在有上行数据需要发送时,终端设备可以在非授权频谱上发送指示信息,该指示信息可以指示在时域上在该指示信息之后存在上行数据,如果不存在需要发送的上行数据,则可以无需发送指示信息。
其中,终端设备在发送该指示信息之前,可以进行LBT操作,如果该LBT操作成功,则可以发送该指示信息。
可选地,在本申请实施例中,能够用于发送指示信息的资源可以是周期性的,在每个发送周期,终端设备可以确定是否存在待发送的上行数据,如果存在,可以在当前周期发送指示信息,其中,在发送指示信息之前,可以进行LBT操作,如果LBT操作成功,则可以发送上行数据,如果LBT操作不成功,则可以在下一周期继续执行LBT操作,以发送指示信息,并进一步发送上行数据。
应理解,该指示信息的资源也可以是非周期的,本申请实施例对此不作具体限定。
可选地,在本申请实施例中,终端设备可以基于指示信息的配置信息发送该指示信息。
该指示信息的配置信息可选地可以包括以下中的至少一个:该指示信息所占用的时域资源、频域资源、功率控制参数、所采用的序列、调制编码方式。

其中,指示信息与上行数据的关联关系可以是指示信息与上行数据在资源占用上的关联关系。例如,上行数据距离指示信息相差几个时间单元(例如,时隙,符号等),上行数据距离指示信息相差几个子载波等。
关联于该上行数据的HARQ进程的信息可以包括该上行数据的HARQ进程的标识(Identifier,ID)、针对是新传还是重传的数据、冗余版本(Redundancy Version,RV)中的至少一个。
该上行数据所占用的资源可以是上行数据实际占用的一个资源,也可以是实际占用的一个资源所属的资源集合。
例如,该上行数据所占用的时域资源可以是上行数据实际占用的一个时域资源,也可以是实际占用的一个时域资源所属的时域资源集合。
例如,该上行数据所占用的频域资源可以是上行数据实际占用的一个频域资源,也可以是实际占用的一个频域资源所属的频域资源集合。
例如,该上行数据所占用的时频域资源可以是上行数据实际占用的一个时频域资源,也可以是实际占用的一个时域资源所属的时频域资源集合。
可选地,该上行数据所占用的时域资源是通过在该指示信息中携带以下中的至少一种指示的:该时域资源的索引(例如,在一个时域资源集合中的索引)、该时域资源所属的时频域资源的索引(例如,在一个时频域资源集合中的索引)、该时域资源相对于参照点(例如,指示信息所占用的时域资源)的偏移、该时域资源的大小。

可选地,在本申请实施例中,终端设备可以基于预配置信息,该终端设备向该网络设备发送该上行数据。此时,终端设备可以不在指示信息中携带该预配置信息,也即不携带上行数据的配置信息。
其中,预配置信息指示以下中的至少一种:该指示信息与该上行数据的关联关系、关联于该上行数据的HARQ进程的信息、该上行数据的数据块大小、该上行数据所占用的时域资源、该上行数据所占用的频域资源、该上行数据的调制编码等级、发送该上行数据所采用的多天线模式。
在本申请实施例中,基于预配置信息发送数据,可以做到提前准备数据,即无需等到接收调度信息后准备,减小了传输时延。
应理解,在本申请实施例中,在指示信息中可以携带部分实现上行数据接收的信息,其他部分信息可以是预配置信息。
例如,指示信息中可以携带该指示信息与该上行数据的关联关系和/或关联于该上行数据的HARQ进程的信息、以及预配置信息可以包括该上行数据的数据块大小、该上行数据所占用的时域资源、该上行数据所占用的频域资源、该上行数据的调制编码等级、发送该上行数据所采用的多天线模式中的至少一种。
可选地,在本申请实施例中,终端设备可以基于该上行数据与该指示信息的关联关系,该终端设备发送该上行数据。其中,该关联关系可以预设(例如,基于协议预设、通过高层信令预设、通过物理层信令预设、通过MAC层信令预设,或者半持续或半静态方式预设)在终端设备上的,或者可以通过指示信息指示给网络设备。
正如上文所述,指示信息与上行数据的关联关系可以是指示信息与上行数据在资源占用上的关联关系。例如,上行数据距离指示信息相差几个时间单元(例如,时隙,符号等),上行数据距离指示信息相差几个子载波等。
可选地,在本申请实施例中,该指示信息与该上行数据在时域上是不连续的,或者也可以是连续的。
其中,本申请实施例提到的指示信息与上行数据在时域上连续或连续可以是基于符号级的、基于时隙级的。
例如,如果是基于符号级的,则指示信息与上行数据连续可以指两者之间无相隔符号,指示信息与上行数据不连续可以指两者之间存在相隔的符号。
例如,如果是基于时隙级的,则指示信息与上行数据连续可以指两者之间无相隔时隙,指示信息与上行数据连续可以指两者之间存在相隔的时隙。
在本申请实施例中,在指示信息与上行数据在时域上是不连续的,可以用于网络侧资源协调,终端设备侧准备数据,以及该两者可以同步进行,减少时延。
可选地,在本申请实施例中,该指示信息与该上行数据间隔的时间单元大于或等于阈值。该阈值可以网络设备预设的、可以是终端设备确定的、也可以是基于协议预设的。
其中,该阈值是基于以下中的至少一种确定的:
该终端设备准备该上行数据的时间、该网络设备解码该指示信息的时间、该网络设备避免其他终端设备在该上行数据所占用的资源上进行上行传输的时间。
其中,该终端设备准备上行数据的时间可以包括对数据进行编码的时间等。该网络设备避免其他终端设备在该上行数据所占用的资源上进行上行传输的时间可以是网络设备在解码到该指示信息之后,向其他终端设备发送另一指示信息以及其他终端设备接收到该另一指示信息的时间,该另一指示信息指示其他终端设备不在该终端设备进行上行数据的传输。
为了便于理解,以下结合图3和图4进行说明。
在301中,UEA确定数据到达,也即确定存在需要发送的上行数据。
在302中,UEA向基站发送数据发送指示信息,指示时域上在该数据发送指示信息之后存在需要发送的上行数据。
在303中,基站检测数据发送指示信息。如果检测到执行304,如果没有检测到,后续继续检测。
在304中,基站向UEB发送抢占指示信息,其中,此处提到的UEB可以是可能需要或者已经确定需要在该UEA的上行数据的占用资源上进行上行传输的UE。例如,UEA的上行数据的占用资源可以属于配置给UEB的用于上行传输的半静态配置的资源,或者可以为对UEB进行调度的资源等。
在306中,UEB检测基站发送的抢占指示信息,如果检测到执行307,如果没有检测到,则继续检测。
在307中,基于检测到的抢占指示信息,停止数据传输。
例如,如图4所示,UEA的上行传输中的上行数据需要占用资源1中的资源11,而资源1原本需要或者可能需要传输UEB的上行数据,则基站可以指示UEB在资源11上停止传输,而在资源1上除资源11之外的资源12上进行上行传输。
可选地,在本申请实施例中,该指示信息可以与调度请求(Scheduling Request,SR)具有相同的格式。此时,与上行数据一起传输的还可以包括用于对上行数据进行解调的DMRS,例如,如图5所示。在该种情况下,指示信息复用现有信令,无需额外设计开销。
应理解,图5中所示的SR是指与SR具有相同格式的指示信息。其中,除了SR之外,还可以存在其他的专用信息用于实现本申请实施例提到的指示信息的功能。
可选地,在本申请实施例中,该指示信息为第一解调参考信号(demodulation reference signal,DMRS)。其中,该第一DMRS用于解调该上行数据,例如,如图6所示。在该方案中,DMRS可以同时具有指示和解调功能,提高传输效率。
其中,在图6所示的方案中,除了作为示信息的DMRS,也可以伴随上行数据发送DMRS,用于实现对上行数据的导频增强解调性能。
可选地,在本申请实施例中,该指示信息为上行控制信息(Uplink Control Information,UCI)和/或用于解调UCI的第二DMRS。例如如图7所示,该UCI可以本申请实施例提到的指示信息。
可选地,在本申请实施例中,可以随着UCI传输用于解调UCI的DMRS,用于解调UCI的DMRS也可以用于解调上行数据,此时,随着上行数据,可以不再发送用于解调该上行数据的DMRS。在该方案中,利用UCI作为指示信息,可以增加上行传输的灵活性。
可选地,在本申请实施例中,该UCI可以用于指示该上行数据的配置信息。
其中,图5-图7所示的指示信息与数据之间相差的准备时间可以是终端设备进行上行数据准备的时间。
可选地,在本申请实施例中,网络设备可以预配置上行数据的配置信息,或者指示信息的配置信 息。
例如,网络设备可以配置:指示信息的周期,偏移,频域资源和序列参数(例如循环移位值等);和/或配置:上行数据传输资源的周期,偏移,时域/频域资源长度和参考信号等;和/或配置:指示信息和上行数据数据传输资源之间的对应关系,例如指示信息所在时隙a,则对应的上行数据传输资源在SR之后且离SR最近;又例如,指示信息所在时隙(slot)(满足Mod(slot,4)=a)对应第(a+1)上行数据传输资源配置集合中,在SR之后且离SR最近的上行数据传输资源。
例如,网络设备可以配置:指示信息的周期,偏移,频域资源和序列参数(循环移位值);和/或配置:上行数据传输资源的时频域资源长度和参考信息等,与指示信息之间的相对时频关系等。
其中,网络设备可以通过高层信令配置、高层信令和物理层信令(MAC层信令)共同配置,半持续配置或半静态配置等。
因此,在本申请实施例中,终端设备向网络设备发送指示信息,该指示信息用于指示在时域上在该指示信息之后存在上行数据,在时域上发送该指示信息之后,该终端设备向该网络设备发送该上行数据,因此可以通过指示信息来指示某些资源被占用,便于网络设备进行资源协调,可以不用预留(例如,半静态或半持续地)上行数据的资源,从而避免资源浪费。

其中,终端设备在发送该指示信息之前,可以进行LBT操作,如果该LBT操作成功,则可以发送该指示信息。
可选地,该指示信息与该预配置的资源的时间间隔可以基于网络设备指示其他终端设备在该预配置的资源上进行上行传输的时间、和/或其他终端设备准备上行数据的时间来确定。
