Description

一种时隙类型指示方法、确定方法及装置
本申请要求在2017年1月6日提交国家专利局、申请号为201710011444.9、发明名称为“一种时隙类型指示方法、确定方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种时隙类型指示方法、确定方法及装置。
背景技术
在未来的第五代移动通信系统(The 5th Generation，5G)中，存在4种可能的时隙(slot)类型，分别为主上行(Uplink-dominant，UL-dominant)slot，全上行(UL-only)slot，主下行(DL-dominant)slot以及全下行(DL-only)slot。其中，UL-dominant slot、DL-dominant slot以及DL-only slot均包含下行控制信道，只有UL-only slot不包含下行控制信道。
5G系统引入了动态时分双工(Time Division Duplexing，TDD)机制，在该机制下，系统的上下行子帧配比以slot为粒度动态变化。基站需要在每一个slot上动态通知终端该slot的类型。在现有方案中，对于一个slot，若该slot的类型为除了UL-only类型以外的slot类型，基站都可以通过该slot包含的下行控制信道通知终端该slot的类型。但对于UL-only类型的slot，由于其不包含下行控制信道，基站无法在UL-only类型的slot中通知当前slot类型。因此，目前基站如何向终端通知UL-only slot的slot类型，是一个亟待解决的问题。

结合前面的描述，如图2所示，为本申请实施例提供的一种时隙类型指示方法流程示意图。
步骤201：网络设备生成第一指示信息，其中，所述第一指示信息指示出第一时隙的时隙类型，当所述第一时隙的时隙类型为预定义类型时，所述第一指示信息还用于指示第二时隙是否为全上行时隙，所述第一时隙为包括下行控制信道的时隙。
步骤202：所述网络设备通过所述第一时隙的下行控制信道发送所述第一指示信息。

步骤201中，第一时隙的时隙类型可以为UL-dominant slot、DL-dominant slot以及DL-only slot中的任意一种，具体根据实际情况确定。
本申请实施例中，所述预定义类型可以为主上行时隙或主下行时隙。
可选的，网络设备可以与终端设备之间预先约定预定义类型，也可以由网络设备通过高层信令对预定义类型进行半静态配置，终端设备可以通过接收到的高层信令确定预定义类型。
其中，高层信令可以为主信息块(Master Information Block,MIB)，系统信息块(System Information Block，SIB)，或无线资源控制(Radio Resource Control,RRC)信令，或其他具有类似特征的高层信令。
可选的，本申请实施例中，第二时隙可以为所述第一时隙之后的第一个动态配置类型的时隙，即第二时隙可以为与第一时隙相邻、且位于第一时隙之后的时隙，或者第二时隙为与第一时隙不相邻、且位于第一时隙之后的时隙。
需要说明的是，这里描述的“动态配置”是指，网络设备可以动态的根据实际情况配置时隙的类型。换言之，网络设备可以以一个时隙的时长为粒度对时隙进行配置。
需要说明的是，全上行时隙可以是指只包括上行信道的时隙，例如UL-only slot。
本申请实施例中，所述第一指示信息可以为第一组预设值或者第二组预设值，其中，第一组预设值包括第一预设值和第二预设值。
当所述第一指示信息为所述第一组预设值时，所述第一指示信息指示出所述第一时隙的时隙类型为预定义类型。进一步的，当所述第一指示信息为所述第一组预设值中的第一预设值时，所述第一指示信息指示所述第二时隙为全上行时隙；当所述第一指示信息为所 述第一组预设值中的第二预设值时，所述第一指示信息指示所述第二时隙不为全上行时隙。
当所述第一指示信息为所述第二组预设值时，所述第一指示信息指示出所述第一时隙的时隙类型。
进一步的，所述第二组预设值中可以包括第三预设值和第四预设值。当所述第一指示信息为所述第二组预设值中的第三预设值时，所述第一指示信息指示所述第一时隙为全下行时隙；当所述第一指示信息为所述第二组预设值中的第四预设值时，所述第一指示信息指示所述第一时隙为主下行时隙。
可选的，所述第一组预设值和第二组预设值可以复用所述第一指示信息中的比特位。
举例来说，第一指示信息包括2个比特位。如果预定义类型为主上行时隙，第一组预设值包括10和11，第二组预设值包括00和01，第一指示信息指示出的内容可以如表1所示：
表1
Figure PCTCN2017119053-appb-000001
结合表1，当第一指示信息为00时，指示出第一时隙的时隙类型为全下行时隙；当第一指示信息为01时，指示出第一时隙的时隙类型为主下行时隙。当第一指示信息为10时，指示出第一时隙的时隙类型为预定义类型(即主上行时隙)、第二时隙的时隙类型不为全上行时隙；当第一指示信息为11时，指示出第一时隙的时隙类型为预定义类型、第二时隙的时隙类型为全上行时隙。
当然以上只是示例，第一指示信息还可以有其他形式，在此不再赘述。
步骤202中，网络设备可以通过第一时隙的下行控制信道发送包括所述第一指示信息的广播信令，从而实现发送所述第一指示信息。
终端在步骤203中接收到第一指示信息之后，在步骤204中，终端设备可以根据第一指示信息确定第一时隙以及第二时隙的时隙类型或者确定第一时隙的时隙类型。
当终端设备根据第一指示信息确定第二时隙的时隙类型不为全上行时隙时，可能还需要在所述第二时隙上进行广播信令的侦听，用以确定所述第二时隙的类型；当终端设备根据第一指示信息确定第二时隙的时隙类型为全上行时隙时，可以不用在所述第二时隙上进行广播信令的侦听。
需要说明的是，本申请实施例中，下行控制信道上用于发送所述第一指示信息的时频资源可以为预定义或半静态配置。相应的，所述下行控制信道上用于发送所述第一指示信息的子载波间隔也可以为预定义或半静态配置的。具体如何进行预定义或半静态配置，可以根据实际情况实现，在此不再赘述。
结合前面的描述，如图3所示，为本申请实施例提供的一种时隙类型指示方法流程示意图。
参见图3，该方法包括：
步骤301：网络设备生成第二指示信息，其中，所述第二指示信息指示出第三时隙之后的M个时隙中每个时隙的时隙类型是否为全上行时隙，所述第三时隙为包括下行控制信道的时隙，M为大于0的正整数。
其中，全上行时隙可以是指只包括上行信道的时隙，例如UL-only slot。
步骤302：所述网络设备通过所述第三时隙的下行控制信道发送所述第二指示信息。
步骤303：终端设备在第三时隙的下行控制信道接收网络设备发送的第二指示信息；所述第二指示信息指示出所述第三时隙之后的M个时隙中每个时隙的时隙类型是否为全上行时隙；所述第三时隙为包括下行控制信道的时隙；M为大于0的正整数。
步骤304：所述终端设备根据所述第二指示信息确定所述M个时隙中每个时隙的时隙类型是否为全上行时隙。
步骤301中，所述M个时隙可以为连续的M个动态变化的时隙，例如，如图4所示，图4中，M个时隙在时域上连续，且均为可以动态变化的时隙。需要说明的是，这里描述的“动态变化的时隙”是指，网络设备可以动态的根据实际情况配置时隙的类型。
当然，所述M个时隙也可以为不连续的M个动态变化的时隙，即至少存在一个被配置为指定类型的时隙位于所述M个时隙中的两个时隙之间。例如，M等于8，如图5所示，图5中，时隙#1至时隙#8为第三时隙之后的动态变化的时隙，时隙#9和时隙#10为被配置为指定类型的时隙，时隙#9位于时隙#4和时隙#5之间，时隙#10位于时隙#6和时隙#7之间，导致时隙#1至时隙#8在时域上不连续。
需要说明的是，第三时隙之后的M个时隙中不包括所述第三时隙，第三时隙可以与所述M个时隙中的第一个时隙相邻，也可以与所述M个时隙中的第一个时隙之间间隔至少一个时隙。第三时隙与所述M个时隙中的第一个时隙之间间隔至少一个时隙时，间隔的时隙的数量可以由网络设备与终端设备之间预先约定，也可以由网络设备通过高层信令向终端设备进行指示。
本申请实施例中，第二指示信息可以包括M个比特位，所述M个比特位中的每个比特位唯一指示所述M个时隙中的一个时隙的类型是否为全上行时隙。
具体的，针对所述M个比特位中的第N个比特位，若所述第N个比特位的值为第一预设值，则与所述第N个比特位对应的时隙的类型是全上行时隙，若所述第N个比特位的值为第二预设值，则与所述第N个比特位对应的时隙的类型不是全上行时隙，其中，N为大于0的正整数，且N小于等于M。
举例来说，M为4，第一预设值为1，第二预设值为0。当第二指示信息为1010时，指示出所述M个时隙中的第一个时隙和第三个时隙的类型是全上行时隙、所述M个时隙中的第二个时隙和第四个时隙的类型不是全上行时隙。
当然，以上只是示例，M还可以为其他取值，在此并不限定。需要说明的是，本申请实施例中，M的值，可以由网络设备与终端设备之间预先约定，也可以由网络设备通过高层信令向终端设备发送所述M。
本申请实施例中，高层信令可以为主信息块(Master Information Block,MIB)，系统信息块(System Information Block，SIB)，或无线资源控制(Radio Resource Control,RRC)信令，或其他具有类似特征的高层信令。
可选的，第二指示信息也可以包括Q个比特位，所述Q个比特位的取值与所述M个时隙中全上行时隙的位置具有映射关系，Q大于0，且小于或等于M。举例来说，M为4， Q为2。Q个比特位的取值与M个时隙中全上行时隙的位置的映射关系可以如表2所示。
表2
Q个比特位的取值 M个时隙中全上行时隙的位置
00 第一个时隙
01 第一个时隙、第二个时隙
10 第二个时隙、第三个时隙
11 第三个时隙、第四个时隙
当终端设备确定接收到的第二指示信息为00时，可以确定第三时隙之后的M个时隙中的第一个时隙为全上行时隙。其他情况可以依次类推，在此不再赘述。
当然，以上只是示例，第二指示信息还可以有其他形式，在此不再逐一举例说明。
步骤302中，网络设备在通过第三时隙的下行控制信道发送第二指示信息的同时，还可以通过所述下行控制信道发送第三指示信息，所述第三指示信息指示出所述第三时隙的时隙类型。
可选的，第三时隙的时隙类型可以为UL-dominant slot、DL-dominant slot以及DL-only slot中的任意一种。
进一步的，本申请实施例中，网络设备还可以发送第四指示信息，所述第四指示信息指示目标周期内的以下一项或多项配置：
所述目标周期内的所有时隙中，上行控制信道在一个时隙中所占用的符号数量；
所述目标周期内的所有时隙中，下行控制信道在一个时隙中所占用的符号数量。
需要说明的是，所述目标周期中，可能不是每个时隙都包括上行控制信道或者下行控制信道，当第四指示信息同时指示出上行控制信道所占用的符号数量和下行控制信道所占用的符号数量时，指示的是包括上行控制信道和下行控制信道的时隙中每个控制信道所占用的符号数量、只包括上行控制信道的时隙中上行控制信道所占用的符号数量、只包括下行控制信道的时隙中下行控制信道所占用的符号数量。
当第四指示信息只指示出上行控制信道所占用的符号数量时，包括上行控制信道和下行控制信道的时隙中下行控制信道所占用的符号数量可以为预设值；相应的，当第四指示信息只指示出下行控制信道所占用的符号数量时，包括上行控制信道和下行控制信道的时隙中上行控制信道所占用的符号数量可以为预设值。
需要说明的是，第四指示信息指示出的上行控制信道在一个时隙中所占用的符号数量可以有多个值，相应的，第四指示信息指示出的下行控制信道在一个时隙中所占用的符号数量可以有多个值。
举例来说，第四指示信息指示出目标周期内的所有时隙中，上行控制信道占用的符号数量与下行控制信道占用的符号数量可以为如下组合：
上行控制信道占用1个符号，下行控制信道占用1个符号；
上行控制信道占用1个符号，下行控制信道占用2个符号；
上行控制信道占用2个符号，下行控制信道占用1个符号；
上行控制信道占用2个符号，下行控制信道占用2个符号。
上述方法，可以适用于，目标周期内，不同时隙中的上行控制信道所占用的符号数量不同的场景，和/或，不同时隙中下行控制信道所占用的符号数量不同的场景。
本申请实施例中，第四指示信息可以有多种实现方式。第一种可能的实现方式中，所 述第四指示信息为广播系统信息，在该实现方式下，所述目标周期为所述广播系统信息的发送周期。
第二种可能的实现方式中，所述第四指示信息为使用公共搜索空间资源发送的公共控制信息，在该实现方式下，所述目标周期为所述网络设备半静态配置或预定义的。
第三种可能的实现方式中，所述第四指示信息为使用公共搜索空间资源发送的广播调度信令调度的广播数据信息，在该实现方式下，所述目标周期为所述网络设备半静态配置或预定义的。
当然，以上只是示例，第四指示信息还可以有其他的实现方式，在此不再赘述。
步骤304中，终端设备接收到第二指示信息之后，可以根据第二指示信息确定所述M个时隙中每个时隙的时隙类型是否为全上行时隙。
具体的，针对所述M个时隙中的第N个时隙，所述终端设备若确定所述第N个时隙的类型是全上行时隙，则可以不在所述第N个时隙上进行广播信令的侦听，用以确定所述第N个时隙的类型。
针对所述M个时隙中的第N个时隙，所述终端设备若确定所述第N个时隙的类型不是全上行时隙，则可以通过所述第N个时隙的下行控制信道中承载的第五指示信息确定所述第N个时隙的时隙类型；所述第五指示信息指示出所述第N个时隙的时隙类型。所述第N个时隙的时隙类型可以为UL-dominant slot、DL-dominant slot以及DL-only slot中的任意一种，具体根据实际情况确认。
结合前面的描述，下行控制信道中还可以包括第三指示信息，此时，终端设备还可以根据所述第三指示信息确定所述第三时隙的时隙类型。
进一步的，所述终端设备还可以接收所述网络设备发送的第四指示信息。所述第四指示信息指示的内容可以参考步骤302中的描述，在此不再赘述。
可选的，所述终端设备接收所述网络设备发送的第四指示信息之后，还可以根据所述第三指示信息以及所述第四指示信息确定所述第三时隙中上行控制信道所占用的符号数量以及下行控制信道所占用的符号数量。
举例来说，每个时隙共包括k个符号。下上行转换占用的符号数量可是i，i是预定义的，或者由物理层信令动态指示，或者由高层信令半静态配置的。第四指示信息指示出目标周期内的所有时隙中，上行控制信道占用的符号数量与下行控制信道占用的符号数量为如下组合：
上行控制信道占用1个符号，下行控制信道占用1个符号；
上行控制信道占用1个符号，下行控制信道占用2个符号；
上行控制信道占用2个符号，下行控制信道占用1个符号；
上行控制信道占用2个符号，下行控制信道占用2个符号。
此时，终端设备确定第三时隙的时隙类型为DL-only slot时，如果确定所述第三时隙的下行控制信道占用1个符号，则可以确定所述下行控制信道占用1个符号，下行数据信道占用k-1个符号。

终端设备确定第三时隙的时隙类型为UL-dominant slot时，如果确定所述第三时隙的上行控制信道占用1个符号，所述下行控制信道占用2个符号：则确定所述上行控制信道占用1个符号，所述下行控制信道占用2个符号，下上行转换占用i个符号，上行数据信道占用k-3-i个符号。
终端设备确定第三时隙的时隙类型为UL-dominant slot时，如果确定所述第三时隙的上行控制信道占用2个符号，所述下行控制信道占用1个符号：则确定所述上行控制信道占用2个符号，所述下行控制信道占用1个符号，下上行转换占用i个符号，上行数据信道占用k-3-i个符号。
终端设备确定第三时隙的时隙类型为UL-dominant slot时，如果确定所述第三时隙的上行控制信道占用2个符号，所述下行控制信道占用2个符号：则确定所述上行控制信道占用2个符号，所述下行控制信道占用1个符号，下上行转换占用i个符号，上行数据信道占用k-4-i个符号。
终端设备确定第三时隙的时隙类型为DL-dominant slot时，如果确定所述第三时隙的上行控制信道占用1个符号，所述下行控制信道占用1个符号：则确定所述上行控制信道占用1个符号，所述下行控制信道占用1个符号，下上行转换占用i个符号，下行数据信道占用k-2-i个符号。
终端设备确定第三时隙的时隙类型为DL-dominant slot时，如果确定所述第三时隙的上行控制信道占用1个符号，所述下行控制信道占用2个符号：则所述上行控制信道占用1个符号，所述下行控制信道占用2个符号，下上行转换占用i个符号，下行数据信道占用k-3-i个符号。
终端设备确定第三时隙的时隙类型为DL-dominant slot时，如果确定所述第三时隙的上行控制信道占用2个符号，所述下行控制信道占用1个符号：则所述上行控制信道占用2个符号，所述下行控制信道占用1个符号，下上行转换占用i个符号，下行数据信道占用k-3-i个符号。
