具体实施方式
图1A为本申请实施例的应用场景示意图，如图1A所示，本实施例的应用场景中可以包括：发送端和接收端。其中，所述发送端和所述接收端可以统称为通信设备。所述通信设备可以获取预设信号的起始位置和第一阈值，所述第一阈值用于确定所述预设信号的候选时域传输单元与特定时域传输单元冲突时的冲突解决方式；从所述起始位置开始，根据所述第一阈值发送或接收所述预设信号。这里，对发送端来说，具体可以为所述起始位置开始，根据所述第一阈值发送所述预设信号；对于接收端来说，具体可以为所述起始位置开始，根据所述第一阈值接收所述预设信号。需要说明的是，发送端和接收端是相对概念，当设备1向设备2发送时，设备1可以认为是发送端，设备2可以认为是接收端。当设备2向设备1发送时，设备2可以认为是发送端，设备1可以认为是接收端。
需要说明的是，本申请实施例可以应用于任何涉及时域传输单元的通信系统，例如长期演进(long term evolution，LTE)系统、窄带物联网(narrow band internet of things，NB-IoT)、5G新空口(new radio，NR)系统、全球移动通信系统(global system for mobile communication，GSM)，移动通信系统(universal mobile telecommunications system，UMTS)，码分多址接入(code division multiple access，CDMA)系统，以及新的网络系统等。例如，如图1B所示，本实施例提供的通信系统中可以包括：基站(base station，BS)、用户设备(user equipment，UE)1-UE6。其中，当基站作为发送端时，UE1、UE2、UE3和UE5可以作为基站对应的接收端。当基站作为接收端时，UE1、UE2、UE3和UE5可以作为基站对应的发送端。当UE5作为接收端时，UE4和UE6可以作为UE5对应的发送端。当UE5作为发送端时，UE4和UE6可以作为UE5对应的接收端。
所述终端，也可以称为用户设备，可以包括但不限于智能手机(如Android手机、IOS手机等)、多媒体设备、流媒体设备、个人电脑、平板电脑、掌上电脑、移动互联网设备(mobile internet devices，MID)或穿戴式智能设备等互联网设备等。
所述基站可以是LTE中的演进型基站(evolved NodeB，eNB)，或者第五代(5G)移动通信系统(也称为新空口(new radio，NR))中的基站可以称为5G基站(gNodeB，gNB)，或者中继站，或者车载设备、可穿戴设备以及未来5G网络中的接入网设备或者未来演进的公共陆地移动网(public land mobile network，PLMN)网络中的接入网设备等，本申请不做限定。
可选的，所述特定时域传输单元具体可以为固定用于传输一种或多种特定信号、 特定信道或特定数据等的时域传输单元。进一步的，所述特定时域传输单元可以为固定用于传输系统消息块(system information block，SIB)x的时域传输单元，x为大于1的整数。进一步可选的，窄带物联网中，固定用于传输除SIB1-NB之外的其他系统消息块的时域传输单元，例如为SIB2-NB、SIB3-NB等。
可选的，所述时域传输单元可以为时隙或子帧，或其它时间单位，本申请不做限定。
可选的，所述预设信号具体可以为发送端通过起始位置以及最大持续时长控制其发送的任意信号。进一步可选的，所述预设信号可以为唤醒信号(wake up signal，WUS)。
可选的，所述候选时域传输单元可以理解为期望用于发送或接收所述预设信号的时域传输单元，具体的，所述候选时域传输单元可以与所述预设信号的起始位置、最大持续时长相关联。所述候选时域传输单元与所述特定时域传输单元冲突可以理解为候选时域传输单元为特定时域传输单元。其中，最大持续时长可以通过时间表示，例如10毫秒(ms)；或者，也可以通过时域传输单元的个数表示，例如10个时域传输单元。当1个时域传输单元对应1ms时，10ms与10个时域传输单元两者可以是等价的。
假设最大持续时长为10个时域传输单元，以下参照图2A-图2C对于延迟方式和丢弃方式作如下说明：
当候选时域传输单元未与特定时域传输单元冲突时，可以用于传输预设信号的时域传输单元为如图2A中最大持续时长T范围内时域传输单元。
当候选时域传输单元中两个点填充的时域传输单元为特定时域传输单元，且对于这两个点填充的特定时域传输单元采用延迟方式时，可以用于传输预设信号的时域传输单元为如图2B中T+T’范围内无填充的时域传输单元，其中T’为两个特定时域传输单元的时长。
当候选时域传输单元中两个点填充的时域传输单元为特定时域传输单元，且对于这两个点填充的时域传输单元采用丢弃方式时，可以用于传输预设信号的时域传输单元为如图2C中T范围内无填充的时域传输单元。
通过上述图2A-图2C可以看出，对于冲突的时域传输单元，采用延迟方式解决冲突并不会影响可以用于传输预设信号的时域传输单元的个数。然而，采用丢弃方式解决冲突会影响可以用于传输预设信号的时域传输单元的个数，即可以用于传输预设信号的时域传输单元的个数与采用丢弃方式解决冲突的特定时域传输单元的个数之和，与最大持续时长对应的时域传输单元个数相同。
需要说明的是上述图2A-图2中，一个小的矩形格子可以表示一个时域传输单元。
以通信系统为窄带物联网(narrow band internet of things，NB-IoT)，发送端为基站，接收端为终端，用于传输窄带物理广播信道(narrowband physical broadcast channel，NPBCH)、窄带主同步信号(narrowband primary synchronization signal，NPSS)、窄带辅同步信号(narrowband subsidiary synchronization signal，NSSS)和SIB1-NB的时域传输单元为固定采用延迟方式解决冲突的时域传输单元，用于传输SIB1-NB之外的SIB的时域传输单元为特定时域传输单元，时域传输单元为子帧为例：当对于所有特定时域传输单元均采用丢弃方式时，可以用于传输预设信号的时域传输单元为如图3A 中时间T1范围内无填充的时域传输单元；当对于所有特定时域传输单元均采用延迟方式时，可以用于传输预设信号的时域传输单元为如图3B中时间T2范围内无填充的时域传输单元。
参照图3A和图3B，当对于所有特定时域传输单元均采用丢弃方式时，可以用于传输预设信号的时域传输单元的个数仅为6个时域传输单元，可以用于传输预设信号的时域传输单元的个数较少，存在信号的适用覆盖范围较小的问题。当对于所有特定时域传输单元均采用延迟方式时，可以用于传输预设信号的时域传输单元的时间跨度较大，接收端接收预设信号的最大窗口长度为74个时域传输单元，接收端接收预设信号的最大窗口长度较大，存在接收端耗电量较大的问题。即，现有技术中，不考虑具体情况，均采用丢弃方式或延迟方式的处理方式，存在可能导致接收端耗电量较大，或者，信号的适用覆盖范围较小的问题。
可以看出，图3A中无线帧1和无线帧2的全部子帧以及无线帧3的前9个子帧均为预设信号的候选时域传输单元。图3B中无线帧1-无线帧7的全部子帧以及无线帧8的前4个子帧均为预设信号的候选时域传输单元。需要说明的是，图3A和图3B中，主要讨论了用于传输SIB1-NB之外的SIB的时域传输单元为特定时域传输单元与候选时域传输单元冲突时的冲突解决方式，对于用于传输NPBCH、NPSS、NSSS和SIB1-NB的时域传输单元与候选时域传输单元冲突时的冲突解决方式可以固定为延迟方式。
需要说明的是，图3A和图3B中，以时域传输单元为子帧，最大持续时长为20个子帧，一个无线帧包括10个子帧，预设信号的起始位置为无线帧1的第一个子帧为例。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图4为本申请一实施例提供的通信方法的流程图，本实施例的执行主体可以为通信设备。如图4所示，本实施例的方法可以包括：
步骤401，获取第一阈值和预设信号的起始位置。
本步骤中，所述第一阈值用于确定所述预设信号的候选时域传输单元与特定时域传输单元冲突时的冲突解决方式。所述预设信号的起始位置可以通过配置获得，或者也可以协议约定，本申请对此并不作限定。所述第一阈值可以通过配置获得，也可以协议约定，本申请对此并不作限定。当所述第一阈值通过配置获得，且所述通信设备为基站时，本实施例的方法还可以包括：向接收端发送指示信息，所述指示信息用于指示所述第一阈值。
当所述第一阈值通过配置获得，且所述通信设备为终端时，本实施例的方法还可以包括：接收发送端发送的指示信息，所述指示信息用于指示所述第一阈值。可选的，所述指示信息可以包括所述第一阈值，或者所述指示信息可以包括所述第一阈值与所述预设信号的最大持续时长的比例关系。
例如，最大持续时长为20，当第一阈值为5时，指示信息可以指示4，接收端可以通过20除以4得到第一阈值5。
又例如，最大持续时长为20，当第一阈值为5时，指示信息可以指示
Figure PCTCN2018086602-appb-000001
接收端 可以通过20乘以
Figure PCTCN2018086602-appb-000002
得到第一阈值5。
所述冲突解决方式可以包括延迟方式、丢弃方式或放弃方式。其中，对于接收端，放弃方式具体可以理解为放弃接收预设信号，即不接收预设信号；对于发送端，放弃方式可以理解为放弃发送预设信号，即不发送预设信号。可选的，可以根据所述第一阈值确定对于与特定时域传输单元冲突的所有候选时域传输单元均采用延迟方式；或者，可以根据所述第一阈值确定对于与特定时域传输单元冲突的所有候选时域传输单元均采用丢弃方式；或者，可以根据所述第一阈值确定对于与特定时域传输单元冲突的所有候选时域传输单元采用部分延迟且部分丢弃方式；或者，可以根据所述第一阈值确定放弃发送或接收预设信号。
这里，通过所述第一阈值用于确定所述预设信号的候选时域传输单元与特定时域传输单元冲突时的冲突解决方式，使得不同特定时域传输单元的冲突解决方式可以根据第一阈值确定，避免了不考虑具体情况，均采用丢弃方式或延迟方式的处理方式时，可能导致接收端耗电量较大，或者，信号的适用覆盖范围较小的问题。
步骤402，从所述起始位置开始，根据所述第一阈值发送或接收所述预设信号。
本步骤中，在发送或接收预设信号时，并不是不考虑具体情况，均采用丢弃方式或延迟方式，而是根据用于确定所述预设信号的候选时域传输单元与特定时域传输单元冲突时的冲突解决方式的第一阈值发送或接收所述预设信号。
根据第一阈值的具体作用的不同，可选的，可以通过如下方式1-方式3中的任意一种具体实现从起始位置开始根据第一阈值发送或接收所述预设信号。
方式1
步骤402具体可以包括：从所述起始位置开始，对于第m个所述特定时域传输单元采用第一冲突解决方式，m为大于0且小于或等于所述第一阈值的整数。
进一步可选的，当从所述起始位置开始，还存在第n个特定时域传输单元，n为大于所述第一阈值的整数时，步骤402还可以包括：对于第n个所述特定时域传输单元采用第二冲突解决方式，发送或接收所述预设信号。
可选的，所述第一冲突解决方式为延迟方式，所述第二冲突解决方式为丢弃方式；或者，所述第一冲突解决方式为丢弃方式，所述第二冲突解决方式为延迟方式。
方式1中，通过对于第m个特定时域传输单元采用第一冲突解决方式，而对于第n个特定时域传输单元采用第二冲突解决方式，可以实现冲突的特定时域传输数量较多时，两种冲突解决方式的折中，避免不考虑具体情况，均采用丢弃方式或延迟方式时，可能导致接收端耗电量较大，或者，信号的适用覆盖范围较小的问题。
需要说明的是，冲突的特定时域传输单元的数量可以小于或等于第一阈值，此时采用对于所有特定时域传输单元均采用第一冲突解决方式。由于冲突的特定时域传输单元的数量较小，可以认为不会存在由于对于特定时域传输单元不考虑具体情况，均采用延迟方式或丢弃方式而导致接收端耗电量较大，或者，信号的适用覆盖范围较小的问题。
例如，假设最大持续时长为20个时域传输单元，各时域传输单元的作用以及起始位置如图5所示，传输SIB1-NB之外的SIB的时域传输单元为特定时域传输单元，且第一阈值为5，第一冲突解决方式为延迟方式，第二冲突解决方式为丢弃方式，则从 所述起始位置开始，对于第m个所述特定时域传输单元采用第一冲突解决方式，对于第n个所述特定时域传输单元采用第二冲突解决方式，发送或接收所述预设信号时，可以用于传输预设信号的时域传输单元为如图5中时间T3范围内无填充的时域传输单元。
通过图5可以看出，采用方式1时，可以用于传输预设信号的时域传输单元的个数为9个时域传输单元，与图3A所示的可以用于传输预设信号的时域传输单元的个数为6个时域传输单元相比，增加了可以用于传输预设信号的时域传输单元的个数，从而解决了信号的适用覆盖范围较小的问题。
通过图5可以看出，采用方式1时，接收端接收预设信号的最大窗口长度为35个时域传输单元，与图3B所示的接收端接收预设信号的最大窗口长度为74个时域传输单元相比，减少了接收预设信号的最大窗口长度，从而解决了接收端耗电量较大的问题。
需要说明的是，图5中以时域传输单元为子帧，最大持续时长为20个子帧，一个无线帧包括10个子帧，预设信号的起始位置为无线帧1的第一个子帧为例。
方式2
步骤402具体可以包括：根据所述预设信号的最大持续时长，确定从所述起始位置开始对于所述特定时域传输单元采用延迟方式时，接收所述预设信号的最大窗口长度；
判断所述最大窗口长度与第二阈值的差异程度是否大于或等于所述第一阈值；所述第二阈值与所述最大持续时长相关联；
若所述差异程度大于或等于所述第一阈值，则从所述起始位置开始，采用丢弃方式发送或接收所述预设信号。
方式2中，通过如果采用延迟方式会导致接收端接收预设信号的最大窗口长度增加很多，则采用丢弃方式，从而避免接收端耗电量较大的问题。
进一步的，若所述差异程度小于所述第一阈值，则从所述起始位置开始，采用延迟方式发送或接收所述预设信号。这里，通过如果采用延迟方式不会导致接收端接收预设信号的最大窗口长度增加很多，则采用延迟方式，从而在保证接收端耗电量在合理范围内的同时，也能保证信号的适用覆盖范围。
可选的，所述第二阈值与所述最大持续时长相关联，具体可以为：所述第二阈值等于所述最大持续时长对应的窗口长度；或者，根据所述最大持续时长确定所述第二阈值。进一步可选的，所述根据所述最大持续时长确定第二阈值可以包括：将根据所述预设信号的最大持续时长确定的，从所述起始位置开始对于所述特定时域传输单元采用丢弃方式时，接收所述预设信号的最大窗口长度，作为所述第二阈值。
可选的，所述最大窗口长度与第二阈值的差异程度可以为所述最大窗口长度与所述第二阈值的差值。
例如，假设最大持续时长为20个时域传输单元，第二阈值等于所述最大持续时长对应的窗口长度20，最大窗口长度为74，最大窗口长度与第二阈值的差值为74-20＝54，则当第一阈值等于20时，54大于20，采用丢弃(adopt drop)方式；当第一阈值等于60时,54小于60，采用延迟(adopt postpone)方式。
方式3
步骤402具体可以包括：判断从所述起始位置开始，目标时长范围内所述特定时域传输单元的个数是否小于或等于所述第一阈值；所述目标时长与所述预设信号的最大持续时长相关联；
若从所述起始位置开始，目标时长范围内所述特定时域传输单元的个数小于或等于所述第一阈值，则从所述起始位置开始，发送或接收所述预设信号。
方式3中，通过如果目标时长范围内特定时域传输单元的个数较小，则从起始位置开始，发送或接收所述预设信号，可以确保特定时域传输单元不会对可以用于传输预设信号的时域传输单元的个数，以及接收端接收预设信号的最大窗口长度带来较大影响，从而解决了与特定时域传输单元信号冲突带来的信号的适用覆盖范围较小，或者，接收端耗电量较大的问题。
需要说明的是，这里，对于方式3中，从所述起始位置开始，发送或接收所述预设信号的过程中，特定时域传输单元的冲突解决方式，并不作限定。例如，可以采用延迟方式或丢弃方式。
进一步的，若从所述起始位置开始，目标时长范围内所述特定时域传输单元的个数大于所述第一阈值，则不发送或接收所述预设信号(可以理解为放弃本次发送或接收预设信号)。这里，通过如果目标时长范围内特定时域传输单元的个数较多，则不发送或接收所述预设信号，避免了特定时域传输单元的个数较多时，对发送或接收所述预设信号的影响，从而解决了与特定时域传输单元冲突带来的信号的适用覆盖范围较小，或者，接收端耗电量较大的问题。
可选的，所述目标时长与所述最大持续时长相关联，具体可以为：所述目标时长等于所述最大持续时长；或者，根据所述最大持续时长确定所述目标时长。进一步可选的，所述根据所述最大持续时长确定目标时长可以包括：将根据所述最大持续时长确定的，从所述起始位置开始对于所述特定时域传输单元采用丢弃方式时，接收所述预设信号的最大窗口长度对应的时长，作为所述目标时长。
需要说明的是，在图6所示实施例中，作为通信双方的接收端和发送端，其从所述起始位置开始，根据第一阈值发送或接收预设信号的具体方式应一致。例如，发送端根据所述第一阈值采用上述方式一发送预设信号，接收端也可以根据第一阈值采用上述方式一接收预设信号。
本实施例中，通过获取第一阈值和预设信号的起始位置，所述第一阈值用于确定所述预设信号的候选时域传输单元与特定时域传输单元冲突时的冲突解决方式，从所述起始位置开始，根据所述第一阈值发送或接收所述预设信号，使得不同特定时域传输单元的冲突解决方式可以根据第一阈值确定，避免了不考虑具体情况，均采用丢弃方式或延迟方式时，可能导致接收端耗电量较大，或者，信号的适用覆盖范围较小的问题。
图6为本申请另一实施例提供的通信方法的流程图，本实施例的执行主体可以为通信设备。如图6所示，本实施例的方法可以包括：
步骤601，判断从预设信号的起始位置开始，目标时长范围内是否存在特定时域传输单元。
本步骤中，所述目标时长与所述预设信号的最大持续时长相关联。例如，如图2B所示，假设目标时长为7个时域传输单元对应的时长，则可以确定目标时长范围内存在特定时域传输单元。若从所述起始位置开始，目标时长范围内不存在所述特定时域传输单元，则执行步骤602。
可选的，所述目标时长与所述最大持续时长相关联，具体可以为：所述目标时长等于所述最大持续时长；或者，根据所述最大持续时长确定所述目标时长。进一步可选的，所述根据所述最大持续时长确定目标时长可以包括：将根据所述最大持续时长确定的，从所述起始位置开始对于所述特定时域传输单元采用丢弃方式时，接收所述预设信号的最大窗口长度对应的时长，作为所述目标时长。
进一步的，若从所述起始位置开始，目标时长范围内存在所述特定时域传输单元，则结束，或者，执行步骤603。
需要说明的是，关于获取起始位置的具体方式，可以参见上述步骤401中的相关描述，在此不再赘述。
步骤602，从所述起始位置开始发送或接收所述预设信号。
本步骤中，对于从所述起始位置开始发送或接收所述预设信号的过程中，特定时域传输单元的冲突解决方式，并不作限定。例如，可以采用延迟方式或丢弃方式。
步骤603，不发送或接收所述预设信号。
本步骤中，不发送或接收所述预设信号，可以理解为放弃本次发送或接收预设信号。
本实施例中，通过判断从预设信号的起始位置开始，目标时长范围内是否存在特定时域传输单元，若从所述起始位置开始，目标时长范围内不存在所述特定时域传输单元，则从所述起始位置开始发送或接收所述预设信号，可以确保特定时域传输单元不会对可以用于传输预设信号的时域传输单元的个数，以及接收端接收预设信号的最大窗口长度带来影响，从而解决了与特定时域传输单元信号冲突带来的适用覆盖范围较小，或者，接收端耗电量较大的问题。
