具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。

可选地,5G系统或5G网络还可以称为新无线(New Radio,NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱可以被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,可以不向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存,通信设备在免授权上进行通信时,可以遵循LBT原则。且为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长可以不超过最大信道占用时间(Maximum Channel Occupation Time,MCOT)。
在使用免授权频谱的系统中,网络设备发送下行信道需要进行LBT,且一次占用信道的时间有限制,因此下行信道和信号的传输有可能是不连续的。而终端设备并不知道网络设备何时开始占用下行信道进行传输,因此需要不断的检测下行信道,如盲检测 PDCCH信道,这样会造成终端设备的耗电。为了减少终端设备的耗电,一种解决方案是在网络设备进行信道侦听的结果为空闲后,网络设备发送指示信号给终端,以通知终端设备获得下行传输机会。对于终端设备而言,平时仅需要监听该指示信号,当基于该指示信号获知网络设备抢占到下行信道之后,终端设备可以开始接收相应的下行信道或信号,例如PDCCH,参考信号等。在收到该指示之前,终端可以不检测除指示信号之外的信道或信号。以下提供了一种可以高效检测该下行信道或信号的方式。
图2是根据本申请实施例的通信方法200的示意性流程图。该方法200可以由终端设备执行,可以包括以下内容中的至少部分内容。
在210中,终端设备在免授权频谱上接收网络设备发送的第一信号,该第一信号用于指示网络设备获得免授权频谱的信道资源。
在220中,终端设备基于第一信号,确定第二信号的第一时域资源位置。
其中,第二信号用于指示网络设备实现利用获得的免授权频谱的信道资源与终端设备进行通信所需获取的信息,或第二信号为下行参考信号。
在230中,终端设备基于第一时域资源位置,在免授权频谱上接收网络设备发送的第二指示信号。
图3是根据本申请实施例的通信方法300的示意性流程图。该方法300可以由网络设备执行,可以包括以下内容中的至少部分内容。
在310中,网络设备在免授权频谱上向终端设备发送第一信号,该第一信号用于指示网络设备获得免授权频谱的信道资源。
在320中,网络设备基于第一信号,确定第二信号的第一时域资源位置。
在330中,网络设备在免授权频谱上向终端设备发送第二信号。
下面将结合图2和图3进一步描述本申请实施例的通信方法。应理解,下文描述的内容即可以应用于方法200,也可以应用于方法300。
当网络设备在免授权频谱上进行下行传输时,可以先进行信道侦听。当信道侦听结果为信道空闲时,网络设备可以在免授权频谱上向终端设备发送第一信号,以通知终端设备信道抢占成功,将在未来的一段时间与终端设备进行通信。
应理解,在本申请实施例中,第一信号也可以称为节能信号。
相应地,终端设备可以在免授权频谱上获取第一信号。
可选地,终端设备获取第一信号的方式有很多种,本申请实施例不作具体限定。例如,终端设备可以采用盲检测的方式获取第一信号。
在网络设备发送第一信号后,网络设备可以基于第一信号,确定第二信号的第一时域资源位置。确定第一时域资源位置后,网络设备可以基于第一时域资源位置,在免授权频谱上向终端设备发送第二信号。
相应地,在终端设备接收到第一信号后,终端设备可以基于第一信号,确定第一时域资源位置。终端设备确定第一时域资源位置后,可以基于第一时域资源位置,在免授权频谱上接收网络设备发送的第二信号。
可选地,网络设备与终端设备进行通信所需获取的信息可以包括但不限于时隙结构、信道使用时长、信道使用带宽和网络设备的属性信息中的至少一个。其中,网络设备的属性信息可以包括网络设备的运营商信息等,本申请实施例对此不作具体限定。
在本申请实施例中,时隙结构可以包括至少一个时隙的时隙结构,时隙结构可以表示为至少一个时隙中的每个时隙内的各个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号的状态,比如某个符号是上行符号、下行符号还是保护符号。
在第二信号指示多个时隙的时隙结构时,该多个时隙的时隙结构可以相同,也可以不相同。
例如,若第二信号指示3个时隙的时隙结构,该3个时隙的时隙结构可以都为{DDDDDDDDDDDDDD},其中,D表示下行符号。
再例如,若第二信号指示3个时隙的时隙结构,该3个时隙中的第一个时隙的时隙结构可以为{DDDDDDDDDDDDDD},第二个时隙的时隙结构可以为{DDUUUUUDXDUUDD},第三个时隙的时隙结构可以为{DDUUUUUDXDUUDD},其中,U表示上行符号,X表示灵活状态符号,网络设备可以根据调度情况,将灵活状态符号配置为上行符号或下行符号。
作为一种示例,时隙结构可以用时隙编号表示。其中,一个时隙编号对应一组时隙结构。
不同时隙编号对应的时隙数量可以相同,但是对应的时隙结构不同,可以是其中的一个时隙的时隙结构不同,也可以多个时隙的时隙结构分别不同。
可选地,时隙编号与时隙结构的对应关系可以是预设的。
作为一种可能,时隙编号与时隙结构的对应关系可以是网络设备预先配置的。
作为一种可能,时隙编号与时隙结构的对应关系可以是协议预先约定好,设置在终端设备和网络设备上的。
可选地,第二信号指示时隙结构可以理解为:第二信号显示指示时隙结构;或第二信号隐式指示时隙结构。
第二信号显示指示时隙结构可以包括:第二信号直接指示时隙结构,例如,指示一个时隙的时隙结构,第二信号可以携带14比特,分别指示14个符号是上行符号、下行符号还是保护符号。
在一种情况下,第二信号隐式指示时隙结构可以包括:第二信号指示时隙结构对应的时隙编号。
在终端设备接收到该时隙编号后,可以根据预设的时隙编号与时隙结构的对应关系,以及接收到的时隙编号,确定时隙结构。
例如,存在256个时隙编号,每个时隙编号分别指示四个时隙的一种时隙结构,则终端设备接收到该时隙编号之后,即可以获知4个时隙的时隙结构。
可选地,信道使用时长可以表示为在网络设备抢占信道后,占用信道的时间,可以从第一信号的传输时间开始计时,也可以从第二信号的传输时间开始计时。
可选地,在本申请实施例中,第二信号可以是PDCCH,可以在PDCCH中携带指示比特,指示网络设备实现利用获得的免授权频谱的信道资源与终端设备进行的通信所需获取的信息。当然,本申请实施例也可以具有其他的实现方式来实现该指示作用。
作为一种示例,第二信号可以基于第二信号的序列,指示网络设备实现利用获得的免授权频谱的信道资源与终端设备进行通信所需获取的信息。
可选地,第二信号可以通过第二信号的序列长度指示时隙结构。
可选地,第二信号的序列长度可以一一对应于时隙结构。
例如,第二信号的一种序列长度对应时隙结构1,第二信号的另一种序列长度为5对应时隙结构2。
可选地,第二信号可以通过第二信号的序列种类指示时隙结构。
例如,第二信号的一种序列种类可以对应时隙结构1,第二信号的另一种序列种类可以对应时隙结构2。
可选地,第二信号可以通过第二信号的序列循环偏移量指示时隙结构。
例如,第二信号的一种序列循环偏移量可以对应时隙结构1,第二信号的另一种序列循环偏移量可以对应时隙结构2。
作为一种示例,第二信号可以基于第二信号的资源位置,指示网络设备实现利用获得的免授权频谱的信道资源与终端设备进行通信所需获取的信息。
例如,第二信号在资源位置1时,指示时隙结构1,第二信号在资源位置2时,指示时隙结构2。
可选地,可以基于第一信号的资源位置与第二信号的资源位置的位置差,指示网络 设备实现利用获得的免授权频谱的信道资源与终端设备进行通信所需获取的信息。
例如,第一信号的资源位置与第二信号的资源位置的位置相差H个符号可以对应时隙结构1,第一信号的资源位置与第二信号的资源位置的位置相差T个符号可以对应时隙结构2。其中,H和T为大于或等于1的正整数。可选地,第二信号可以为下行信道或下行参考信号。
可选地,下行信道可以包括物理下行控制信道(Physical Downlink Control Channel,PDCCH)、增强的物理下行控制信道(Enhanced Physical Downlink Control Channel,EPDCCH)、机器类通信物理下行控制信道(Machine Type Communication Physical Downlink Control Channel,MPDCCH)或窄带物理下行控制信道(Narrowband Physical Downlink Control Channel,NPDCCH)等。
可选地,下行参考信号可以包括下行同步信号(Synchronization Signal),相位跟踪参考信号(Phase Tracking Reference Signal,PT-RS),下行解调参考信号(DeModulation Reference Signal,DMRS),信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)、同步信号块(Synchronization Signal block,SSB)等。其中,下行同步信号可用于接入网络和无线资源管理测量,下行DMRS可用于下行信道的解调,CSI-RS可用于下行信道的测量、下行时频同步或相位跟踪,PT-RS也可用于下行信道的测量、下行时频同步或相位跟踪。
可选地,第一时域资源位置可以包括第二信号的特定时域资源位置,也可以包括第二信号所在的时域资源集合的位置。
当第二信号为PDCCH时,第二信号所在的时域资源集合为PDCCH控制资源集(Control-Resource Set,CORESET),第一时域资源位置可以为PDCCH CORESET的位置。
可选地,PDCCH CORESET可以是网络设备预先配置的,也可以是协议预先约定的。
需要说明的是,若第一时域资源位置为第二信号所在的时域资源集合的位置,终端设备在确定时域资源集合的位置后,可以在第二信号所在的资源集合进行盲检测,以获取第二信号,本申请实施例不作限制。
例如,当第二信号为PDCCH,第一时域资源位置为PDCCH CORESET的位置时,终端设备可以通过盲检测的方式从PDCCH CORESET中确定PDCCH的位置。
在第一时域资源位置可以包括第二信号的特定时域资源位置时,终端设备可以直接在该位置上获取第二信号,无需进行盲检测,此时,该第二信号可以是下行参考信号。
可选地,第一时域资源位置可以包括第二信号所在的时隙和/或在时隙中所在的符号。
应理解,第二信号所在的时隙可以包括一个时隙或多个时隙,第二信号可以占用这些时隙的部分时隙,或者可以占用全部时隙的部分符号。
第二信号所在的时隙中的符号可以是一个符号集合,第二信号可以承载于该符号集合上的部分符号上(此时,需要对第二信号进行盲检测),也可以承载在该符号集合上的全部符号上(此时,可以不对第二信号进行盲检测,直接在该符号集合上获取第二信号)。
应理解,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
可选地,第一时域资源位置在时域上占用至少一个符号。
当第一时域资源位置在时域上占用多个符号时,可选地,该多个符号是连续的。此时,该多个符号可以在一个时隙上。
例如,第一时域资源位置在时域上占用8个符号,该8个符号可以都在同一个时隙上。
当第一时域资源位置在时域上占用多个符号时,可选地,该多个符号可以在多个时隙上,此时,该多个符号在时间上可以连续,也可以不连续。
例如,第一时域资源位置在时域上占用8个符号,该8个符号中的5个符号在时隙1上,3个符号在时隙2上。
可选地,第一时域资源位置与第一信号占用的第二时域资源位置具有预定的时间差,例如,相差预定数量的时隙和/或符号。
其中,第一时域资源位置与第二时域资源位置相差的预定数量的时隙和/或符号可以是预设的。
作为一种可能,预定数量的时隙和/或符号可以是网络设备预先配置的。网络设备可以向终端设备发送第一指示信息,该第一指示信息用于指示第一时域资源位置与第二时域资源位置相差的时隙和/或符号。终端设备接收到第一指示信息后,可以获取到第一时域资源位置与第二时域资源位置相差的时隙和/或符号。
示例性地,第一指示信息可以包括于第一信号中,也可以不包括于第一信号中。当第一指示信息不包括于第一信号中时,本申请实施例对网络设备发送第一信号和第一指示信息的顺序不作限制。比如,网络设备可以先发送第一信号,再发送第一指示信息;网络设备也可以先发送第一指示信息,再发送第一信号。
作为另一种可能,预定数量的时隙和/或符号可以是协议预先规定好,设置在终端设备和网络设备上的。
可选地,在本申请实施例中,若第一信号和第二信号在时域上不连续,在网络设备可以在第一信号和第二信号之间的时间间隔中发送占位信号,以在第一信号和第二信号之间的时间段内,占用免授权频谱的信道。
在一种实现方式中,终端设备基于第一信号,确定第二信号的第一时域资源位置,可以包括:终端设备基于第一信号占用的第二时域资源位置,确定第一时域资源位置。
在该实现方式下,作为一种可能的实施例,终端设备可以基于第一信号所在的时隙位置,确定第一时域资源位置。此时,有两种实现方式:
方式一,第二信号所在的时隙可以为第一时隙,此时,第一时隙可以为第一信号所在的时隙。也就是说,第一信号和第二信号位于相同的时隙。
可选地,第一时隙可以为一个时隙,也可以为多个时隙,本申请实施例不作具体限定。
作为一种示例,第一时域资源位置包括的连续的多个符号可以为第一时隙中预设位置的连续的多个符号。
可选地,该预设位置可以是协议预先规定好的。
可选地,预设位置可以为第一时隙中的最后连续的多个位置。
举例说明,假设第一时域资源位置包括M个连续的符号,其中,M为大于或等于1的整数。如图4所示,预设位置可以为第一信号所在的时隙的最后M个符号。
或者,如图5所示,预设位置可以为第一信号所在的时隙的第8个OFDM符号开始的连续M个符号,其中,OFDM符号的编号从1开始。
作为另一种示例,网络设备可以向终端设备发送第二指示信息,该第二指示信息用于指示第一时域资源位置包括的连续的多个符号为第一时隙中的连续的多个符号。
例如,第二指示信息可以指示第一时域资源位置包括的连续的多个符号为第一信号所在的时隙中最后连续的多个符号。
可选地,第一信号可以包括该第二指示信息。
可选地,第一信号可以不包括该第二指示信息。
此时,本申请实施例对终端设备接收第一信号和第二指示信息的前后顺序不做限制。应理解,本申请实施例中的第一信号和第二指示信息之间的前后关系仅表示逻辑上的前后关系,终端设备接收第一信号和第二指示信息之间还可以接收其他信号。
方式二,第二信号所在的时隙可以为第二时隙,此时,第二时隙可以与第一信号所在的时隙相差至少一个时隙。
可选地,第二时隙可以为一个时隙,也可以为多个时隙,本申请实施例不作具体限定。
作为一种示例,第一时域资源位置包括的连续的多个符号可以为第二时隙中预设位置的连续的多个符号。
可选地,该预设位置可以是协议预先规定好的。
可选地,预设位置可以为第二时隙中的最前连续的多个位置。
举例说明,假设第一时域资源位置包括N个连续的符号,第二信号位于第一信号所在时隙的下一个时隙,N为大于或等于1的整数。如图6所示,预设位置可以为第一信号所在的时隙的下一个时隙的前N个符号。
或者,如图7所示,预设位置可以为第一信号所在的时隙的下一个时隙的第8个符号开始的连续N个符号,其中,符号编号从1开始。
作为另一种示例,网络设备可以向终端设备发送第三指示信息,第三指示信息可以指示第一时域资源位置包括的连续的多个符号为第一时隙中的连续的多个符号。
例如,第三指示信息可以指示第一时域资源位置包括的连续的多个符号为第一信号所在时隙的下一个时隙中最前连续的多个符号。
可选地,第一信号可以包括第三指示信息。
可选地,第一信号可以不包括第三指示信息。
作为另一种可能的实施例,终端设备可以基于第一信号在第一信号所在的时隙中占用的符号位置,确定第二信号所在的时隙。
作为一种示例,终端设备可以基于该符号位置,确定第一信号所在时隙中的剩余符号,再基于剩余符号,终端设备可以确定第二信号所在的时隙。
在一种情况下,若剩余符号的数量大于或等于第一阈值,终端设备可以确定第二信号所在的时隙为第一信号所在的时隙,即第一信号和第二信号位于相同的时隙。
在另一种情况下,若剩余符号的数量小于第二阈值,终端设备可以确定第二信号所在的时隙为第一信号所在时隙的下一个时隙。
可选地,第一阈值与第二阈值可以相同。
再次参考图4和图6,当网络设备抢占到信道,获得免授权频谱的信道资源时,若第一信号所在的时隙中还有较多的符号剩余,比如剩余的符号数量大于图4中的M个符号,则终端设备可以根据图4的方案,确定第二信号与第一信号在相同的时隙。若剩余的符号数量小于图4中的M个符号,终端设备可以根据图6的方案,确定第二信号所在的时隙为第一信号所在时隙的下一个时隙。
作为另一种示例,若剩余符号的数量小于第二阈值,终端设备可以确定第二信号的多个符号中的部分符号所在的时隙为第一信号所在的时隙,另一部分符号所在的时隙为第一符号所在时隙的下一个时隙。
例如,若第一信号所在的时隙中剩余3个符号,第二信号在时域上占用5个符号,则终端设备可以确定第二信号在时域上占用的5个符号中的3个符号所在的时隙为第一信号所在的时隙,第二信号在时域上占用的5个符号中剩余的2个符号所在的时隙为第一信号所在时隙的下一个时隙。
其中,5个符号中的3个符号可以为5个符号中的前3个符号,也可以是5个符号中的任意3个符号,本申请实施例不做限制。
作为另一种可能的实施例,终端设备可以基于第一时域资源位置与第二时域资源位置相差的时隙和/或符号,以及第二时域资源位置,确定第一时域资源位置。
以上描述了可以基于第一信号的第二时域资源位置,确定第二信号的第一时域资源位置。但是本申请实施例并不限于此。本申请还可以采用其他方式确定第二信号的第一 时域资源位置。
例如,终端设备基于第一信号的序列,确定第二信号的第一时域资源位置。
在一种实现方式中,终端设备可以基于第一信号的序列长度,确定第一时域资源的位置。
例如,第一信号的时隙是固定的,则可以基于第一信号的序列长度,确定第二信号在该时隙中的具体符号位置。此时,可以存在多种长度的序列,每种长度的序列,针对第二信号,可以对应不同的符号位置。
在另一种实现方式中,终端设备基于第一信号的序列和第一信号占用的第二时域资源位置,确定第一时域资源位置。
例如,存在多种长度的序列,每种长度的序列可以对应一种时域资源大小,则根据第一信号的序列长度,确定第二信号的时域资源大小,以及可以结合第一信号的时域资源位置,确定该时域资源的起始位置,从而可以基于该起始位置以及该资源大小,确定第一时域资源位置。
例如,可以基于第一信号的时域资源位置,确定第二信号所占用的时隙,可以基于第一信号的序列长度,确定第二信号在该时隙中的具体符号位置。此时,可以存在多种长度的序列,每种长度的序列,针对第二信号,可以对应不同的符号位置。
在另一种实现方式中,终端设备可以基于第一信号的序列种类,确定第一时域资源位置。
例如,第一信号可以存在多种序列种类,不同的序列种类,针对第二信号,可以对应不同的时域资源位置,从而终端设备可以基于第一信号的序列种类,确定第一时域资源位置。
可选地,终端设备也可以基于第一信号的序列循环偏移量,确定第一时域资源位置。
例如,第一信号的序列循环偏移量不同,则第一时域资源位置不同,从而终端设备可以基于第一信号的序列循环偏移量的多少,确定第一时域资源位置。
应理解,以上描述了终端设备基于第一信号确定第一时域资源位置的具体实现方式,网络设备基于第一信号确定第一时域资源位置的实现方式可以参考终端设备确定第一时域资源位置的描述。这里,为了内容过多简洁,不再赘述。
可选地,在本申请实施例中,网络设备与终端设备进行通信所需获取的信息适用的起始时隙可以为第二信号的时隙;或者
网络设备与终端设备进行通信所需获取的信息适用的起始时隙可以为第二信号的时隙的下一个时隙。
例如,当第二信号指示时隙结构时,时隙结构可以在第二信号所在的时隙立即生效,也可以在第二信号所在时隙的下一个时隙生效。
可选地,在本申请实施例中,当第二信号指示至少一个时隙的时隙结构时,若网络设备获得的免授权频谱的信道资源的时隙数量大于第二信号指示的时隙结构的时隙数量时,则网络设备或终端设备可以周期性循环使用第二信号指示的时隙结构,直到将第二信号指示的时隙结构应用于所有免授权频谱的信道资源的时隙。
例如,第二信号指示3个时隙的时隙结构,免授权频谱的信道资源的时隙有6个,则终端设备或网络设备可以将第二信号指示的3个时隙的时隙结构循环在免授权频谱的信道资源的时隙上应用2次。
再例如,第二信号指示3个时隙的时隙结构,免授权频谱的信道资源的时隙有8个,则终端设备或网络设备可以将第二信号指示的3个时隙的时隙结构循环在免授权频谱的信道资源的时隙上使用2次,再将第二信号指示的3个时隙结构中的前两个时隙结构应用于免授权频谱的信道资源中剩余的2个时隙中。
应理解,在本申请实施例中,网络设备或终端设备除了可以周期性循环将第二信号指示的时隙结构,应用于所有免授权频谱的信道资源的时隙外,本申请还可以采用其他 方式将第二信号指示的时隙结构应用于所有免授权频谱的信道资源的时隙。
可选地,若免授权频谱的信道资源的时隙数量不是第二信号指示的时隙结构的时隙数量的整数倍,则网络设备或终端设备可以将第二信号指示的时隙结构在免授权频谱的信道资源的时隙上循环应用整数次,免授权频谱的信道资源中剩余的时隙可以应用第二信号指示的时隙结构中的其中一个时隙结构。
例如,第二信号指示3个时隙的时隙结构时,免授权频谱的信道资源的时隙有8个,则网络设备或终端设备可以在授权频谱的信道资源的时隙上循环使用2次第二信号指示的3个时隙的时隙结构,第二信号指示的3个时隙结构中的其中一个时隙结构可以应用于剩余的2个免授权频谱的信道资源的时隙。
应理解,本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例,而非限制本申请实施例的范围。
可选地,在本申请实施例中,若第二信号指示时隙结构时,时隙结构的子载波间隔可以为当前工作载波或工作的带宽部分的子载波间隔;或
时隙结构的子载波间隔可以为预设置的子载波间隔。
可选地,时隙结构的子载波间隔可以是网络设备预设置的。
可选地,时隙结构的子载波间隔可以是终端设备和网络设备预先约定的。
在网络设备确定第一时域资源位置后,网络设备可以基于第一时域资源位置,向终端设备发送第二信号。
相应地,在终端设备确定第一时域资源位置后,终端设备可以基于第一时域资源位置,接收网络设备发送的第二信号。
应理解,在本申请实施例中,“第一”、“第二”和“第三”等仅仅为了区分不同的对象,但并不对本申请实施例的范围构成限制。
需要说明的是,在不冲突的前提下,本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合,组合之后得到的技术方案也应落入本申请的保护范围。
本申请实施例,在网络设备获得免授权频谱的信道资源后,终端设备可以基于网络设备发送的指示信号,确定下行信号的时域资源位置,从而可以高效地检测下行信号。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
