图1是根据一示例性实施例示出的一种确定上下行切换点的方法的流程图,图2是根据一示例性实施例示出的一种确定上下行切换点的方法的应用场景图;该确定上下行切换点的方法可以用于基站;如图1所示,该确定上下行切换点的方法可以包括以下步骤110-120:
在步骤110中,设置用于确定上下行切换点的配置信息。
本公开实施例中,针对非授权频谱,引入了LBT(Listen Before Talk,先听后说)的机制。也就是说数据发送端在有数据需要发送时,需要先检测信道是否空闲,只有信道处于空闲的状态后,才可以发送数据。发送端可以使用信道的时间通过MCOT(Maximum Channel Occupancy Time,最大信道占用时间)来限制。也就是说数据发送端执行完一次信道检测过程并成功获取信道后,最大的信道占用时间不能超过MCOT定义的时间。
当数据发送端为基站,该基站通过了LBT信道检测并成功获取信道后,将会向终端发送数据,终端需要在相应的位置上发送针对该数据的HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈信息。
由于有的业务对时延要求较高,所以要求终端在MCOT内就进行HARQ的反馈。但是,一个MCOT中可能存在多个上下行切换点,在这种情况下,基站可以先设置用于确定上下行切换点的配置信息,再将该配置信息发送至终端,这样终端就可以根据配置信息确定上下行切换点,从而更好地满足了对时延要求较高的业务需求。另外,终端在获知了上下行切换点的配置信息后,还可以基于自身的需要灵活的调整LBT 的机制,从而可以根据待传输信号或是信令的不同来调整LBT机制,保证待传输信号或是信令传输的性能。
在一实施例中,所述配置信息中可以包括至少一个MCOT内的上下行切换点的位置信息和/或上下行切换的时间长度信息。
在步骤120中,将配置信息发送至终端,以使终端根据配置信息确定上下行切换点。
本公开实施例中,基站将配置信息发送至终端,其目的是为了让终端根据配置信息确定上下行切换点。至于具体采用何种方式将配置信息发送至终端,其实现方式有很多,可以包括但不限于以下两种实现方式:
方式一:基站隐式指示配置信息,终端也基于隐式的指示确定配置信息。
比如:用于隐式指示配置信息的信息为传输单元结构信息,其具体实现过程可参见图3所示实施例。又比如:用于隐式指示配置信息的信息为调度信令,其具体实现过程可参见图4所示实施例。
方式二:基站显式指示配置信息,终端也基于显式的指示确定配置信息。
比如:用于显式指示配置信息的信息为指定信令,其具体实现过程可参见图5所示实施例。又比如:用于显式指示配置信息的信息为指定信号,其具体实现过程可参见图6所示实施例。
在一实例性场景中,如图2所示,包括基站和终端。为了便于终端及时准确地获知不同的上下行切换点,基站可以先设置用于确定上下行切换点的配置信息,再将该配置信息发送至终端,这样终端就可以通过配置信息来获知不同的下行切换点。
由上述实施例可见,通过设置用于确定上下行切换点的配置信息,并将该配置信息发送至终端,这样终端就可以通过配置信息来获知不同的下行切换点,从而避免了终端在非授权载波上进行无效的检测,还提高了终端确定上下行切换点的速度和准确性。
图3是根据一示例性实施例示出的另一种确定上下行切换点的方法的流程图,该确定上下行切换点的方法可以用于基站;该方法建立在图1所示方法的基础上,在执行步骤120时,如图3所示,可以包括以下步骤310-320:

在一实施例中,所述传输单元结构信息可以为传输方向指示信息,所述传输方向指示信息用于指示一个MCOT内包含的传输单元的传输方向,且至少包括第一状态信息、和/或第二状态信息、和/或第三状态信息;所述第一状态信息用于指示传输单元为上行传输,所述第二状态信息用于指示传输单元为下行传输,所述第三状态信息用于指示传输单元为上下行切换点。
比如:如图3A所示,第一状态信息为U,其用于指示传输单元为上行传输;第二状态信息为D,其用于指示传输单元为上行传输;第三状态信息为X,其用于指示传输单元为上下行切换点。与此对应的,终端接收到传输方向指示信息后,可以直接根据第三状态信息(即X)来确定上下行切换点以及切换点的长度信息。
在步骤320中,将传输单元结构信息发送至终端,以使终端根据传输单元结构信息确定配置信息。
本公开实施例中,基站将传输单元结构信息发送至终端,其目的是为了让终端根据传输单元结构信息隐式获知配置信息。

比如:如图4A所示,基站设置的调度信令1中指示了该MCOT中的上行传输从第4个传输单元上开始进行上行传输,则基于预先定义的规则,比如规定起始上行传输单元的前一个传输单元是用于上下行切换的,这样隐式指示了第3个传输单元是用来做上下行切换的。与此对应的,终端接收到的调度信令1中指示了该MCOT中的上行传输从第4个传输单元上开始进行上行传输,基于预先定义的规则,该终端可以隐式获知第3个传输单元是用来做上下行切换的。
在步骤420中,将调度信令发送至终端,以使终端根据调度信令确定配置信息。

本公开实施例中,由于存在一个MCOT中可能存在多个上下行切换点这种情形,终端为了明确这些上下行切换点,可以通过基站发送的配置信息来确定。
至于终端采用何种方式接收配置信息,这是由基站来决定的。比如:基站隐式指示配置信息,终端也基于隐式的指示确定配置信息。又比如:基站显式指示配置信息,终端也基于显式的指示确定配置信息。
