Description

信道占用时间的起始位置确定方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及信道占用时间的起始位置确定方法，信道占用时间的起始位置确定装置，电子设备和计算机可读存储介质。
背景技术
随着终端与基站通信场景的拓展，终端与基站的通信已不限于授权频段，还可以在非授权频段通信。
但是由于非授权频段并非只有终端与基站的通信会占用，其他设备的通信也可能占用非授权频段，所以终端与基站需要通信时，若需要占用非授权频段，发送信息的发送端可以采用LBT(先听后说，Listen Before Talk)检测机制来检测信道是否空闲，具体是检测非授权频段的信道是否空闲，在非授权频段的信道空闲时，才能占用非授权频段进行通信。
而接收信息的接收端需要持续的监听非授权频段的信道，以确定是否接收到发送端的信息，并在接收到发送端发送的信息时，开始接收信息。

具体实施方式
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，而不是全部的实施例。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。
图1是根据本公开的实施例示出的一种信道占用时间的起始位置确定方法的示意流程图。本实施例所示的信道占用时间的起始位置确定方法可以适用于终端，所述终端包括但不限于手机，平板电脑，可穿戴设备等电子设备，所述终端可以作为用户设备与基站通信，并且可以通过授权频段(例如运营商网络的频段)与基站通信，也可以通过非授权频段(例如Wi-Fi网络的频段)与基站通信。
如图1所示，所述信道占用时间的起始位置确定方法可以方法包括以下步骤：
在步骤S1中，根据配置信息确定下行信道占用时间的起始位置的第一周期，和/或上行信道占用时间的起始位置的第二周期；
需要说明的是，对于同一个终端而言，确定第一周期所依据的配置信息和确定第二周期所依据的配置信息，可以是同一个配置信息，也可以是不同的配置信息；
在步骤S2中，根据所述第一周期，周期性地确定是否在非授权频段接收到所 述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息；
在步骤S3中，若在非授权频段接收到基站发送的信息，确定从所述基站接收到所述信息的时间为所述非授权频段的下行信道占用时间的起始位置。
在相关技术中，对于非授权频段的信道的检测机制包括但不限于cat1(无LBT)，cat2(无随机避退LBT)，cat3(采用固定长度竞争窗口的随机退避LBT)和cat4(采用非固定长度竞争窗口的随机退避LBT)，以下主要以cat2和cat4为例，对本公开的实施例进行示例性说明。
图2是一种cat2检测机制的示意图。
如图2所示，基于cat2检测机制，终端与基站通信过程中发送数据的发送端，可以在CCA(Clear Channel Assessment，空闲信道评估)对应的时间内，例如每次CCA对应一个时隙(slot)，检测非授权频段的信道是否被占用，并且每次CCA的间隔以及信道占用时间都是固定的。
在图2中，第一次CCA和第三次CCA对非授权频段的信道检测结果为检测空闲，说明非授权频段的信道未被其他设备占用，那么可以在这两次CCA后占用非授权频段的信道来传输数据，第二次CCA对非授权频段的信道检测结果为检测忙碌，说明非授权频段的信道被其他设备占用，那么在这次CCA后不占用非授权频段的信道传输数据。
图3是一种cat4检测机制的示意图。
如图3所示，基于cat4检测机制，可以在0至竞争窗口长度(CWS,Contention Window Size)之间均匀且随机地生成一个回退计数器的计数值N，N介于0和CWS之间。
当CCA检测到非授权频段的信道空闲，计数器的计数值减1，当CCA检测到非授权频段的信道忙碌，计数器的计数值不变，当计数器的计数值为0，那么立即占用非授权频段的信道。
其中的竞争窗口长度CWS是动态值，可以基于之前发送的数据是否被接收端成功接收，动态地调整CWS，以便根据信道的状态和网络业务负载得到合适的CWS取值，从而在减小发送端之间碰撞和提升信道接入效率之间取得折中。
例如在图3中，发送端第一次向接收端发送数据时，检测信道所采用的CWS为15，计数器的计数值为7，那么在2次CCA检测非授权频段的信道空闲后，4次CCA检测非授权频段的信道忙碌，然后5次CCA检测非授权频段的信道空闲，从而共7次CCA检测非授权频段的信道空闲，计数器的计数值减为0，占用非授权频段的信道向接收端发送数据。
但是接收端未能成功接收到数据，发送端可以在占用非授权频段的信道的期间调整CWS，例如将CWS提高至31，计数器的计数值为20，那么在发送端第二次向接收端发送数据时，在20次CCA检测非授权频段的信道空闲后，占用非授权频段的信道向接收端发送数据。
其中，无论图2所示的cat2检测机制，还是图4所示的cat4检测机制，每次CCA都是基站和终端中发送信息的发送端进行，以及在非授权频段的信道向接收端发送数据，但是接收端并不知道发送端在非授权频段的信道占用时间的起始位置，所以不能确定从什么时刻起开始接收发送端发送的信息，因此需要持续的监听非授权频段的信道，以确定是否接收到发送端的信息，并在接收到发送端发送的信息时，开始接收发送端发送的信息，这接收端造成大量功耗。
根据本公开的实施例，在终端作为接收端的情况下，可以根据配置信息确定下行信道占用时间的起始位置的第一周期，然后根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，若在非授权频段接收到基站发送的信息，确定从所述基站接收到所述信息的时间为所述非授权频段的下行信道占用时间的起始位置。
据此，终端可以周期性地确定是否在非授权频段接收到基站发送的信息，进而当在非授权频段接收到基站发送的信息的情况下，将从基站接收到信息的时间作为非授权频段的下行信道占用时间的起始位置开始接收基站发送的信息，而无需持续地监听非授权频段的信道，从而降低了终端的功耗。
需要说明的是，所述第一周期是下行信道占用时间的起始位置可能的周期，在实际通信过程中，基站可以改变下行信道占用时间的起始位置，从而使得第一周期改变。
根据本公开的实施例，在终端作为发送端的情况下，可以根据配置信息确定上行信道占用时间的起始位置的第二周期，根据第二周期，周期性地在非授权频段空闲 的时段内向基站发送信息。作为接收端的基站则可以根据第二周期，周期性地在非授权频段接收终端发送的信息，若在非授权频段接收到所述终端发送的信息，确定接收到终端发送的信息的时间为非授权频段的上行信道占用时间的起始位置。
据此，基站可以周期性地确定是否在非授权频段接收到终端发送的信息，进而当在非授权频段接收到基站发送的信息的情况下，将从终端接收到信息的时间作为非授权频段的上行信道占用时间的起始位置开始接收终端发送的信息，而无需持续地监听非授权频段的信道，从而降低了基站的功耗。
需要说明的是，所述第二周期是上行信道占用时间的起始位置可能的周期，在实际通信过程中，终端可以改变上行信道占用时间的起始位置，从而使得第二周期改变。
图4是根据本公开的实施例示出的另一种信道占用时间的起始位置确定方法的示意流程图。如图4所示，在根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息之前，所述方法还包括：
在步骤S4中，根据所述配置信息确定在所述第一周期中接收基站发送信息的第一起始时间，和/或在所述第二周期中向基站发送信息的第二起始时间；
其中，所述根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息包括：
在步骤S21中，根据所述第一周期，周期性地从所述第一起始时间开始确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地从所述第二起始时间开始向所述基站发送信息。
在一个实施例中，配置信息还可以指示在第一周期中接收基站发送信息的第一起始时间，那么终端可以周期性地从该第一起始时间开始在非授权频段接收基站发送的信息。
由于第一起始时间是基站在第一周期中较为可能发送信息的时间，因此终端在第一周期中从该第一起始时间开始在非授权频段接收基站发送的信息，便于终端在第一周期中尽快地接收到基站发送的信息，从而尽快地确定下行信道占用时间的起始位置。
在一个实施例中，配置信息还可以指示在第二周期中向基站发送信息的第二起始时间，那么终端可以周期性地从该第二起始时间开始在非授权频段向基站发送信息。
由于第二起始时间可以是基站配置给终端的，那么终端在第二周期中较为可能从第二起始时间开始发送信息，因此基站在第二周期中从该第二起始时间开始在非授权频段接收终端发送的信息，便于基站在第二周期中尽快地接收到终端发送的信息，从而尽快地确定上行信道占用时间的起始位置。
可选地，所述第一周期和/或所述第二周期包括至少一个时隙，所述第一起始时间和/或所述第二起始时间为符号。
在一个实施例中，第一周期可以包含至少一个时隙，第二周期也可以包括至少一个时隙，第一起始时间可以是时隙中的符号，第二起始时间也可以是时隙中的符号。
可选地，所述配置信息用于指示所述第一起始时间和/或所述第二起始时间在所述至少一个时隙中所处的目标符号。
在一个实施例中，配置信息可以直接指示第一起始时间和/或第二起始时间在至少一个时隙中所处的符号，例如以第一起始时间为例，1个时隙包含14个符号为例，第一起始时间位于第一周期对应的至少一个时隙中，例如第一周期为1个时隙，第一起始时间为1个时隙中的第一个符号，那么配置信息可以直接指示第一起始时间在第1个符号，例如第一周期为2个时隙，第一起始时间为第2个时隙中的第1个符号，那么配置信息可以直接指示第一起始时间为第15个符号。
其中，配置信息可以通过位图(bitmap)进行指示，例如配置信息直接指示第一起始时间在第1个符号，那么可以通过信息“10000000000000”进行指示；例如配置信息直接指示第一起始时间在第15个符号，那么可以通过信息“0000000000000010000000000000”进行指示，其中1表示第一起始时间。
可选地，所述配置信息包括第一部分信息和第二部分信息；
其中，所述第一部分信息用于指示所述第一起始时间和/或所述第二起始时间在所述至少一个时隙所处的目标时隙，所述第二部分信息用于指示所述第一起始时间和/或所述第二起始时间在所述目标时隙中所处的目标符号。
在一个实施例中，配置信息可以通过第一部分信息和第二部分信息两部分信息来指示第一起始时间和/或第二起始时间。
以第一起始时间为例，例如第一周期为3个时隙，第一起始时间为第2个时隙中的第13个符号，那么第一部分信息对应比特位的值为010，表示第一起始时间在3个时隙中的第2个时隙，第二部分信息对应比特位的值为1101，表示第一起始时间为目标时隙的第13个符号，从而结合第一部分信息和第二部分信息，就可以确定第一起始时间为第2个时隙的第13个符号。
据此，可以通过比至少一个时隙中全部符号的数量少的比特为来指示第一起始时间，有利于降低配置信息的数据量。
图5是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图。如图5所示，在根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息之前，所述方法还包括：
在步骤S5中，根据所述配置信息确定接收基站发送信息的接收时长，和/或向基站发送信息的发送时长；
其中，所述根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息包括：
在步骤S22中，根据所述第一周期，周期性地持续所述接收时长确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内持续所述发送时长向所述基站发送信息。
在一个实施例中，配置信息还可以指示在第一周期中接收基站发送信息的接收时长，那么终端可以根据所述第一周期，周期性地持续接收时长确定是否在非授权频段接收到所述基站发送的信息。
由于接收时长是基站在第一周期中发送信息较为可能持续的时长，因此终端在第一周期中持续所述接收时长在非授权频段接收基站发送的信息，有利于保证终端仅在基站发送信息的时段内，确定是否接收到基站发送的信息，避免在基站未发送信息的时段内，确定是否接收到基站发送的信息而造成功耗浪费。
其中，图5所示的实施例可以图4所示的实施例相结合，那么终端持续所述接收时长确定是否在非授权频段接收到所述基站发送的信息，可以是从第一起始时间开始持续所述接收时长；也可以是在第一起始时间之后持续所述接收时长，但是持续所 述接收时长的开始时间距离第一起始时间的时长小于预设时长，以便保证在持续所示接收时长内，基站仍在发送信息，终端能接收到基站发送的信息；还可以是在第一起始时间之后持续所述接收时长，但是持续所述接收时长的结束时间要在第一起始时间之后，以便保证在持续所示接收时长内，基站有在发送信息，终端能接收到基站发送的信息。
在一个实施例中，配置信息还可以指示在第二周期中向基站发送信息的发送时长，那么终端可以根据所述第二周期，周期性地持续发送时长向基站发送信息。
由于发送时长可以是基站配置给终端的，也即基站可以确定发送时长，那么终端在第二周期中较为可能持续所述发送时长来向基站发送信息，因此基站在第二周期可以持续发送时长在非授权频段接收终端发送的信息，有利于保证基站仅在终端发送信息的时段内，确定是否接收到终端发送的信息，避免在终端未发送信息的时段内，确定是否接收到终端发送的信息而造成功耗浪费。
图6是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图。如图6所示，在根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息之前，所述方法还包括：
在步骤S6中，根据所述配置信息确定第一类型；
其中，所述若在非授权频段接收到基站发送的信息，确定从所述基站接收到所述信息的时间为所述非授权频段的下行信道占用时间的起始位置包括：
在步骤S31中，若在非授权频段接收到所述基站发送的信息，检测所述基站发送的信息的类型与所述第一类型是否相同；
在步骤S32中，若所述基站发送的信息的类型与所述第一类型相同，确定从所述基站接收到所述信息的时间为所述非授权频段的下行信道占用时间的起始位置。
在一个实施例中，配置信息还可以指示在第一类型，终端在非授权频段接收到基站发送的信息的情况下，可以检测基站发送的信息的类型与第一类型是否相同，并在基站发送的信息的类型与第一类型相同的情况下，才确定从基站接收到所述信息的时间为非授权频段的下行信道占用时间的起始位置。
据此，可以使得终端仅将基站发送第一类型的信息的时间作为下行信道占用时间的起始位置，避免终端误将基站发送其他类型的信息的时间作为下行信道占用时间 的起始位置。
图7是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图。如图7所示，在根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息之前，所述方法还包括：
在步骤S7中，根据所述配置信息确定第二类型；
其中，所述根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息包括：
在步骤S23中，根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送所述第二类型的信息。
在一个实施例中，配置信息还可以指示在第二类型，终端可以在根据第二周期，周期性地在非授权频段空闲的时段内向所述基站发送第二类型的信息。
由于第二类型可以是基站配置给终端的，也即基站可以确定第二类型，基站在非授权频段接收到终端发送的信息的情况下，可以检测终端发送的信息的类型与第二类型是否相同，并在终端发送的信息的类型与第二类型相同的情况下，才确定从终端接收到所述信息的时间为非授权频段的上行信道占用时间的起始位置。
据此，可以使得基站仅将终端发送第二类型的信息的时间作为上行信道占用时间的起始位置，避免基站误将终端发送其他类型的信息的时间作为上行信道占用时间的起始位置。
图8是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图。如图8所示，在根据所述第一周期，周期性地确定是否在非授权频段接收到所述基站发送的信息，和/或根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息之前，所述方法还包括：
在步骤S8中，根据所述配置信息确定预设时域资源；
其中，所述根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息包括：
在步骤S24中，根据所述第二周期，周期性地在非授权频段空闲的时段内的所述预设时域资源向所述基站发送信息。
在一个实施例中，配置信息还可以配置预设时域资源，根据所述第二周期，周期性地在非授权频段空闲的时段内的所述预设时域资源向所述基站发送信息。
由于预设时域资源可以是基站配置给终端的，也即基站可以确定预设时域资源，进而基站可以在非授权频段的预设时域资源接收终端发送的信息。据此，可以使得终端仅在非授权频段空闲的时段内的预设时域资源向所述基站发送信息，并且基站也仅在非授权频段的预设时域资源接收终端发送的信息，有利于避免基站在预设时域资源以外的时域资源(在这些时域资源终端并向基站发送信息)接收终端发送的信息而造成的资源浪费。
可选地，所述配置信息为预先定义(例如基站与终端之间通信协议所预先定义的)或所述基站预先配置的。
可选地，在检测在非授权频段从所述基站接收到的信息的类型之前，所述方法还包括：
确定所述配置信息所配置的所述基站占用所述非授权频段的下行信道的持续时长。
在一个实施例中，配置信息还可以指示终端，基站占用非授权频段的下行信道的持续时长，据此，终端在每个第一周期中确定是否在非授权频段接收到所述基站发送的信息所持续的接收时长，可以小于或等于所述基站占用所述非授权频段的下行信道的持续时长，有利于避免终端在基站占用非授权频段的下行信道的时间段以外接收基站发送的信息，进而避免终端资源的浪费。
图9是根据本公开的实施例示出的一种信道占用时间的起始位置确定方法的示意流程图。本实施例所示的信道占用时间的起始位置确定方法可以适用于基站，所述基站可以与上述实施例中的终端通信，可以通过授权频段(例如运营商网络的频段)与基站通信，也可以通过非授权频段(例如Wi-Fi网络的频段)与基站通信。
如图9所示，所述信道占用时间的起始位置确定方法可以包括以下步骤：
在步骤S1'中，根据第二周期，周期性地在非授权频段接收终端发送的信息；
在步骤S2'中，若在所述非授权频段接收到所述终端发送的信息，确定接收到所述终端发送的信息的时间为所述非授权频段的上行信道占用时间的起始位置。
根据本公开的实施例，在终端作为发送端的情况下，可以根据配置信息确定上 行信道占用时间的起始位置的第二周期，根据第二周期，周期性地在非授权频段空闲的时段内向基站发送信息。作为接收端的基站则可以根据第二周期，周期性地在非授权频段接收终端发送的信息，若在非授权频段接收到所述终端发送的信息，确定接收到终端发送的信息的时间为非授权频段的上行信道占用时间的起始位置。
据此，基站可以周期性地确定是否在非授权频段接收到终端发送的信息，进而当在非授权频段接收到基站发送的信息的情况下，将从终端接收到信息的时间作为非授权频段的上行信道占用时间的起始位置开始接收终端发送的信息，而无需持续地监听非授权频段的信道，从而降低了基站的功耗。
图10是根据本公开的实施例示出的另一种信道占用时间的起始位置确定方法的示意流程图，如图10所示，在根据第二周期，周期性地在非授权频段接收终端发送的信息之前，所述方法还包括：
在步骤S3'中，向所述终端发送配置信息，其中，所述配置信息用于指示所述终端根据所述第二周期，周期性地在非授权频段空闲的时段内向所述基站发送信息。
在一个实施例中，基站可以通过配置信息将第二周期配置给终端，从而使得第二周期具备可控性。另外，第二周期也可以是预先定义的，例如基站与终端之间通信协议所预先定义的。
可选地，所述配置信息还用于指示所述终端在所述第二周期中向基站发送信息的第二起始时间。
在一个实施例中，配置信息还可以指示在第二周期中向基站发送信息的第二起始时间，那么终端可以周期性地从该第二起始时间开始在非授权频段向基站发送信息。
由于第二起始时间可以是基站配置给终端的，那么终端在第二周期中较为可能从第二起始时间开始发送信息，因此基站在第二周期中从该第二起始时间开始在非授权频段接收终端发送的信息，便于基站在第二周期中尽快地接收到终端发送的信息，从而尽快地确定上行信道占用时间的起始位置。
可选地，所述第二周期包括至少一个时隙，所述第二起始时间为符号。
可选地，所述配置信息用于指示所述第二起始时间在所述至少一个时隙中所处的目标符号。
可选地，所述配置信息包括第一部分信息和第二部分信息；
其中，所述第一部分信息用于指示所述第二起始时间在所述至少一个时隙所处的目标时隙，所述第二部分信息用于指示所述第二起始时间在所述目标时隙中所处的目标符号。
图11是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图，如图11所示，在根据第二周期，周期性地在非授权频段接收终端发送的信息之前，所述方法还包括：
在步骤S4'中，向所述终端发送配置信息，其中，所述配置信息用于指示所述终端根据所述第二周期，周期性地在所述非授权频段的预设时域资源向所述基站发送信息；
其中，所述根据第二周期，周期性地在非授权频段接收终端发送的信息包括：
在步骤S11'中，所述根据第二周期，周期性地在所述非授权频段的预设时域资源接收终端发送的信息。
在一个实施例中，配置信息还可以配置预设时域资源，根据所述第二周期，周期性地在非授权频段空闲的时段内的所述预设时域资源向所述基站发送信息。
由于预设时域资源可以是基站配置给终端的，也即基站可以确定预设时域资源，进而基站可以在非授权频段的预设时域资源接收终端发送的信息。据此，可以使得终端仅在非授权频段空闲的时段内的预设时域资源向所述基站发送信息，并且基站也仅在非授权频段的预设时域资源接收终端发送的信息，有利于避免基站在预设时域资源以外的时域资源(在这些时域资源终端并向基站发送信息)接收终端发送的信息而造成的资源浪费。
图12是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图，如图12所示，所述向所述终端发送配置信息包括：
在步骤S41'中，向所述终端以及其他终端发送配置信息；
其中，向不同终端发送的所述配置信息所指示的预设时域资源相同，所述配置信息还用于配置终端在所述预设时域资源向基站发送的信息，且所配置的不同的终端在所述预设时域资源向基站发送的信息正交。
在一个实施例中，若向不同终端发送的配置信息所指示的预设时域资源相同，那么不同的终端将会在同一个预设时域资源向基站发送信息，这可能会造成基站接收 信息出现错误。
对此，可以通过配置信息配置终端在预设时域资源向基站发送的信息，且所配置的不同的终端在预设时域资源向基站发送的信息正交，由于不同的终端在预设时域资源向基站发送的信息正交，不同的终端在同一个预设时域资源向基站发送信息就是正交的，这使得在同一个预设时域资源接收到多个信息的基站，可以正确地将正交的信息解析出来。
例如基站可以预先定义正交4个信号，信号1，信号2，信号3和信号4，然后将信号1配置给终端1，将信号2配置给终端2，将信号3配置给终端3，将信号4配置给终端4，那么终端1，终端2，终端3和终端4可以在同一个预设时域资源分别向基站发送信号1，信号2，信号3和信号4，由于这4个信号是正交的，基站可以准确地解析出每个信号，从而确定出在预设时域资源接收到了终端1，终端2，终端3和终端4发送的信号。
图13是根据本公开的实施例示出的又一种信道占用时间的起始位置确定方法的示意流程图，如图13所示，在根据第二周期，周期性地在非授权频段接收终端发送的信息之前，所述方法还包括：
在步骤S5'中，向所述终端发送配置信息，其中，所述配置信息用于指示所述终端根据所述第二周期，周期性地在所述非授权频段向所述基站发送第二类型的信息；
其中，所述若在所述非授权频段接收到所述终端发送的信息，确定接收到所述终端发送的信息的时间为所述非授权频段的上行信道占用时间的起始位置包括：
在步骤S21'中，若在所述非授权频段接收到所述终端发送的信息，确定接收到所述终端发送的信息的类型与所述第二类型是否相同；
在步骤S22'中，若接收到所述终端发送的信息的类型与所述第二类型相同，确定接收到所述终端发送的信息的时间为所述非授权频段的上行信道占用时间的起始位置。
在一个实施例中，配置信息还可以指示在第二类型，终端可以在根据第二周期，周期性地在非授权频段空闲的时段内向所述基站发送第二类型的信息。
由于第二类型可以是基站配置给终端的，也即基站可以确定第二类型，基站在非授权频段接收到终端发送的信息的情况下，可以检测终端发送的信息的类型与第二类型是否相同，并在终端发送的信息的类型与第二类型相同的情况下，才确定从终端 接收到所述信息的时间为非授权频段的上行信道占用时间的起始位置。
据此，可以使得基站仅将终端发送第二类型的信息的时间作为上行信道占用时间的起始位置，避免基站误将终端发送其他类型的信息的时间作为上行信道占用时间的起始位置。
