Description

指示信息的发送方法和装置 技术领域
本申请涉及通信领域，尤其涉及一种指示信息的发送方法和装置。
背景技术
在无线通信系统中，终端设备有两种状态，一种是连接态，表示终端设备已与网络设备建立了连接，可直接进行通信；一种是空闲态或称为睡眠态，表示终端设备无法与网络设备直接进行通信。
在长期演进(long term evolution，LTE)和新无线(New Radio，NR)通信系统中，可以通过不连续接收(discontinuous reception，DRX)机制或者连接态不连续接收(connected-discontinuous reception，C-DRX)机制降低在连接态的终端设备的功耗。终端设备在没有业务数据发送或者接收时，可以进入空闲态以降低耗电量。当网络设备要向终端设备发送业务数据或者需要终端设备上报一些业务数据时，可以通过寻呼(paging)机制通知终端设备，而空闲态的终端设备会周期性唤醒来监听物理下行控制信道(physical downlink control channel，PDCCH)，检测PDCCH中是否存在寻呼调度消息，若存在寻呼调度消息，且是针对自己的寻呼调度，则空闲态的终端设备切换到连接态，以便发送或者接收业务数据。其中，终端设备唤醒的时间位置称为寻呼机会(paging occasion，PO)。
对于连接态的终端设备，也可以配置连接态DRX机制，在连接态DRX机制中，终端设备会周期性在持续时间(ON duration)内唤醒并监听特定类型的PDCCH信道(例如调度上下行数据的PDCCH)，一旦检测到所述特定类型的PDCCH发送相关下行控制信息(downlink control information，DCI)，则会触发一个DRX非激活定时器(inactivity timer)。
在实际应用中，网络设备并不是在每个PO或者每个持续时间(ON duration)内都会向终端设备发送上述DCI，很多情况下，终端设备通过周期性唤醒来检测上述DCI都属于无效操作，会增加功耗。因此，窄带物联网(narrow band internet of things，NB-IoT)系统和NR系统中引入了唤醒信号(wake-up signal，WUS)功能。即如果在某一个PO或者持续时间(ON duration)中网络设备确定向终端设备发送上述DCI用于调度上下行数据，网络设备会在PO或者持续时间(ON duration)到来之前发送WUS，反之网络设备不会发送WUS。终端设备会在PO或者持续时间(ON duration)到来之前尝试检测WUS，检测到WUS后才在接下来的PO或者持续时间(ON duration)中检测特定类型的PDCCH，用于检测网络设备是否发送上述DCI；否则在接下来的PO或者持续时间(ON duration)中不检测特定类型的PDCCH。由于检测WUS的功耗和复杂度远小于检测特定类型的PDCCH的功耗和复杂度，而且网络设备在空闲时或者配置了连接态DRX机制时发送特定类型的PDCCH的概率并不高，因此WUS功能可以极大的节省终端设备的功耗。
目前，网络设备通过位图(bitmap)来指示多个终端设备的WUS，每个终端设备 的WUS固定对应位图中的一比特位。当某一比特位置位时，表示唤醒对应的终端设备；否则表示不唤醒对应的终端设备。当终端设备的数目多于位图的位数时，会存在多个终端设备固定共用同一比特位的情况，这样固定共用同一比特位的终端设备之间会持续产生WUS冲突，难以做到所有终端设备的公平。

下面对本申请涉及的一些概念进行描述。
DRX机制或C-DRX(连接态的DRX(connected-DRX))机制：
在LTE通信系统中，3GPP提出了DRX机制(进一步地，C-DRX机制)以降低在连接态的终端设备的功耗，如无特别说明，DRX和C-DRX都表示连接态的DRX。下面以C-DRX机制为例进行说明：
如图4所示，为一个C-DRX周期的示意图。一个C-DRX周期包括非激活时间(outside active time)和激活时间(inside active time)两个时间段。非激活时间(outside active time)也可以称为DRX机会(opportunity for DRX)、DRX状态、休眠时间、停止时间、睡眠时间等；激活时间(inside active time)也可以称为激活状态(active state)、唤醒时间、唤醒状态等，本申请对具体名称不作限定。
在非激活时间内，终端设备可以关闭射频发送接收机、基带处理芯片和内存，只保留晶振时钟。或者，可以只监听寻呼无线网络临时标识(paging radio network temporary identity，P-RNTI)、临时小区无线网络临时标识(temporary cell radio network temporary identity，TC-RNTI)、系统消息无线网络临时标识(system information radio network temporary identity，SI-RNTI)等RNTI加掩的PDCCH。具体取决于终端设备的实现方式。
在激活时间内，终端设备唤醒并可以持续监听用于调度新传上下行数据的PDCCH，具体地，通过检测PDCCH中的下行控制信息(downlink control information，DCI)来确定是否是用于调度新传上下行数据的PDCCH，上下行数据包括物理下行共享信道(physical downlink shared channel，PDSCH)和物理上行共享信道(physical uplink shared channel，PUSCH)；接收PDSCH或发送PUSCH；发送混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息。
同一DRX周期内非激活时间和激活时间的占比是可变的。下面结合图4具体来说明：
终端设备在连接态的激活状态下，当激活时间开始时，终端设备会启动一个持续时间定时器(ON duration timer)，该定时器的定时时长为持续时间(ON duration)。终端设备在持续时间(ON duration)内不断监听用于调度新传上下行数据的PDCCH，一旦终端设备接收到该PDCCH，终端设备会启动或重启非激活定时器(inactivity timer)。在非激活定时器超时以前，终端设备可以继续监听特定类型的PDCCH(例如C-RNTI加掩的用于调度上下行数据的PDCCH)。在这种情况下，激活时间的时间长度大于持续时间(ON duration)的时间长度或非激活定时器的定时时长。在激活时间内，每当终端设备收到用于调度新传上下行数据的PDCCH，终端设备都会启动或重 启非激活定时器(inactivity timer)。
如果终端设备在持续时间(ON duration)内没有收到任何调度新传上下行数据的PDCCH并且持续时间定时器超时，或者，终端设备接收到调度新传上下行数据的PDCCH但之后非激活定时器超时，则终端设备将进入非激活时间。对于在持续时间(ON duration)内没有收到任何调度新传上下行数据的PDCCH并且持续时间定时器超时的情况，激活时间(inside active time)的时间长度等于持续时间(ON duration)的时间长度。
在一般情况下，终端设备并不是在持续时间(ON duration)开始时刻才唤醒，而是会在持续时间(ON duration)到来前的几个时隙内先唤醒，并接收下行参考信号以进行时频偏同步，防止终端设备因为长时间休眠造成系统的时钟和工作频率与网络设备出现偏差。同时终端设备也可以先尝试接收下行同步信号和更新系统消息，以防止终端设备从一个小区移动到另一个小区后系统同步和系统消息出现偏差。
唤醒信号(wake-up signal，WUS)功能：
WUS功能首次是在NB-IoT系统中引入的功能，用于进一步降低终端设备的功耗，主要用在无线资源控制(radio resource control，RRC)空闲态的寻呼机制中。
在空闲态中，终端设备一般情况下处于休眠状态，但需要每过一段时间唤醒来尝试接收寻呼调度消息。终端设备唤醒的时间位置称为寻呼机会(paging occasion，PO)。在实际应用中，网络设备并不是在每个PO都会向终端设备发送寻呼调度消息，大多数情况下，终端设备通过周期性唤醒来检测寻呼调度消息都属于无效操作，会增加功耗。因此，NB-IoT系统中引入了WUS功能。即如果在某一个PO中网络设备确定向终端设备发送寻呼调度消息，网络设备会在PO到来之前发送WUS，反之网络设备不会发送WUS。终端设备会在PO到来之前尝试检测WUS，检测到WUS后才在接下来的PO中检测寻呼调度消息，否则在接下来的PO中不检测寻呼调度消息。由于检测WUS的功耗和复杂度远小于检测寻呼调度消息的功耗和复杂度，而且网络设备在空闲时发送寻呼调度消息的概率并不高，因此WUS功能可以极大的降低终端设备的功耗。
基于PDCCH的WUS(可以简称为PDCCH-WUS)：
第三代合作伙伴计划(3rd generation partnership project，3GPP)针对具有DRX功能的终端设备，在NR版本(release)16的功耗节省特性中引入基于PDCCH的WUS功能，即通过PDCCH承载WUS，其可以应用于RRC连接态中，用于指示终端设备是否在之后的一个或多个持续时间(ON duration)内唤醒并监听用于调度上下行数据的PDCCH。。
如图5所示，网络设备发送PDCCH-WUS需要满足如下条件：
1、携带WUS的PDCCH的搜索空间(search space)处于非激活时间(outside active time)内，并且在持续时间(ON duration)之前的一段时间内发送。
2、在后续的持续时间(ON duration)内，存在发送给该终端设备的用于调度PDSCH或PUSCH的PDCCH。也就是说：只有当有上下行数据时，网络设备需要调度终端设备发送PUSCH或者接收PDSCH，则网络设备需要唤醒终端设备，使终端设备进入激活时间监听用于调度上下行数据的PDCCH，此时，网络设备才会发送PDCCH-WUS，否则不发送，或者虽然网络发送了PDCCH-WUS，但是所述PDCCH-WUS是发送给多 个终端的，对于某一个终端配置的固定位置，所述bit可以用于指示这个终端设备是否唤醒。
在一个DRX周期的持续时间(ON duration)到来之前，如果网络设备配置了PDCCH-WUS，则终端设备可以在固定的时间段上的一段频域资源(可以称之为搜索空间)上去检测PDCCH-WUS。
如果终端设备检测到了PDCCH-WUS，则表明在该PDCCH-WUS(或搜索空间)对应的持续时间(ON duration)上存在调度该终端设备发送PUSCH或接收PDSCH的PDCCH，终端设备需要在持续时间(ON duration)上检测PDCCH中的DCI，并根据DCI的指示发送PUSCH或者接收PDSCH。
如果终端设备没有在该频域资源(搜索空间)上检测到PDCCH-WUS，终端设备可以认为在该频域资源(搜索空间)对应的持续时间(ON duration)上不存在针对该终端设备的数据调度，可以不检测PDCCH中的DCI，以达到降功耗的目的。
可以采用新的DCI格式(DCI format)来承载PDCCH-WUS，其能够用于指示至少一个终端设备的WUS信息。该DCI格式可以在组内PDCCH(group common PDCCH)中发送，在公共搜索空间集合(common search space set)中检测。
通过DCI指示PDCCH-WUS，有如下要求：因为PDCCH-WUS的检测块差错率(block error ratio，BLER)目标需要低于0.1％，DCI格式(DCI format)的大小不能太大。指示PDCCH-WUS耗费的资源开销(resource overhead)不能太高，因此通过组内PDCCH的组WUS DCI(group WUS DCI)来指示PDCCH-WUS更有优势。根据PDCCH-WUS指示的特点，漏检率要低于0.1％，对虚警率的要求相对宽松。本申请实施例中，虚警指不需要被唤醒的终端设备被唤醒。
适用于通过组内PDCCH的组WUS DCI来指示PDCCH-WUS的场景可能有如下一些特点：能够通过WUS功能降低功耗的前提是终端设备进行的业务是突发的(bursty)和偶发的(sporadic)的，否则终端设备将在大多数持续时间(On duration)内唤醒。在同一个小区中的所有终端设备之间的业务应该是相互独立的，也就是说很多个终端设备同时在同一段时间进行业务的可能性并不高。
也就是说，可能有很多终端设备(例如N个)需要同时监听组WUS DCI，但是同时需要唤醒的终端设备的数量(例如M个，M可能远小于N)并不多。或者，也有可能同一小区里配置的需要监听组WUS DCI的终端设备并不多。
在设计组WUS DCI的DCI格式时，尽量在同一个DCI中用较少的比特数唤醒N个终端设备中的M个终端(M可能远小于N)。
如图6所示，现有的方案是通过使用位图(bitmap)来指示至少一个终端设备的WUS DCI，每个终端设备的唤醒指示(wake-up indicatin)对应其中一个唯一的固定位置的比特位。当该比特位置位时，表示唤醒该终端设备，否则表示不唤醒该终端设备。该固定位置是由网络通过高层信令半静态配置的。但是上述基于固定位置的位图显然无法满足解决下述问题：
当配置给组WUS DCI的终端设备的数量不是很多时，给每个终端设备配置固定位置的比特位的方式较优，肯定没有虚警(不考虑DCI循环冗余校验(cyclic redundancy check，CRC)虚警)。但是当小区内支持并需要发送组WUS DCI的终端设备的数目 较多时，给每个终端设备分配唯一的固定位置的比特位不现实，因为信令开销太大。
一种解决方式是配置多个终端设备共享同一个比特位，但是这种方式会固定地在共享相同位置的终端之间引入虚警，难以做到所有终端设备的公平。例如，如果终端设备1不需要频繁唤醒而终端设备2需要频繁唤醒，当他们共享同一比特位时，将导致终端设备1也频繁唤醒，从而产生虚警。
本申请实施例提供了一种指示信息的发送方法和装置，根据终端设备的标识信息和预设时间段的时间信息中的至少一项来确定针对该终端设备的唤醒指示在WUS DCI的位置(示例性的，当WUS DCI为位图时，该位置可以为位图中比特位的位置)，实现不同终端设备的唤醒指示在WUS DCI中的位置之间的随机或伪随机分布，以尽量做到所有终端设备的公平。
具体的，如图7所示，本申请实施例提供了一种指示信息的发送方法，包括S701-S704：
S701、网络设备根据第一信息确定第一指示信息在至少一个第二指示信息中的位置。
首先对第一信息的相关内容进行描述：
第一信息可以包括第一终端设备的标识信息和第一预设时间段的时间信息中的至少一项。可选的，第一信息还可以包括第一终端设备的分量载波组的标识(CC group ID)。
示例性的，第一终端设备的标识信息可以为C-RNTI等。
第一预设时间段的时间信息可以包括以下信息的至少一项：第一预设时间段的时隙(slot)编号、符号(symbol)编号、时隙内的控制资源集合(control resource set，CORESET)的编号、第一预设时间段中WUS监听机会(monitoring occasion)的编号。时隙内的CORESET的编号对于同一个时隙内设置多个WUS监听机会的情况较为有用，例如，同一个时隙内多个WUS监听机会在时间上相互重叠，此时可以使用CORESET作为时间信息对这些WUS监听机会进行区分。
第一预设时间段可以指包括唤醒信号机会(WUS occasion)的时间段，即网络设备发送组WUS DCI的时间段，在本申请实施例中，即后文所述的发送第二指示信息的时间段。
第一终端设备为处于不连续接收(DRX)非激活时间(outside active time)的待唤醒终端设备中的一个。本申请实施例中，待唤醒终端设备指前文所述的需要监听组WUS DCI的终端设备。也就是说，待唤醒终端设备不仅支持DRX功能，而且进行的业务是突发的(bursty)和偶发的(sporadic)的，同一个小区中的待唤醒终端设备之间的业务应该是相互独立的。
下面对第一指示信息和第二指示信息的相关内容进行描述：
第一指示信息用于指示第一终端设备在预设时间内进入激活时间(inside active time)。第二指示信息用于指示至少一个待唤醒终端设备在对应的时间内进入激活时间(inside active time)。可选的，第二指示信息可以通过位图来指示，每个终端设备的第一指示信息可以对应位图的一个比特位。
如前文针对DRX机制所描述的，本申请实施例中，激活时间也可以称为唤醒时间、 唤醒状态等，因此，本申请实施例中，如无特别说明，将指示终端设备在对应时间内进入激活时间简称为唤醒。
本申请实施例对第二指示信息唤醒的待唤醒终端设备的数量不作限定，并且各待唤醒终端设备的激活时间是独立的，即可能相同或不同。示例性的，所有待唤醒终端设备可能有N个，第二指示信息可能唤醒全部或部分(例如M个，M可能远小于N)待唤醒终端设备。
可选的，第二指示信息指示的待唤醒终端设备指在第一预设时间段之后的第二预设时间段内能够进入激活时间的终端设备。其中，第二预设时间段包括该终端设备进入激活时间的起始时隙，或者，第二预设时间段包括该终端设备在激活时间内任意一段连续的时隙。
示例性的，如图8所示，第二指示信息1的发送时间段为第一预设时间段1，第二指示信息2的发送时间段为第一预设时间段2。第二预设时间段1在第一预设时间段1之后，并且不在第一预设时间段2之后，因此第二指示信息1可以指示的待唤醒终端设备包括：在第二预设时间段1内能够在对应时间内进入激活时间1的终端设备1，以及，在第二预设时间段1内能够在对应时间内进入激活时间2的终端设备2。第二预设时间段2在第一预设时间段2之后，因此第二指示信息2可以指示的待唤醒终端设备包括：在第二预设时间段2内能够在对应时间内进入激活时间4的终端设备3。
从中可以看出，第二指示信息1指示的待唤醒终端设备可以不包括在第二预设时间段2内能够在对应时间内进入激活时间4的终端设备3，可以减少第二指示信息1的携带的第一指示信息的数量。也就是说，位于前面的第二指示信息指示的待唤醒终端设备可以不包括后面的第二指示信息能够指示的待唤醒终端设备，可以降低前面的第二指示信息携带的第一指示信息的数量。
需要说明的是，第二时间段的时间信息(例如，时间长度、起始时隙、终止时隙)可以通过与第一时间段之间的偏移来确定，具体的，上述偏移包括：例如，第二时间段的起始时隙与第一时间段的起始时隙之间的偏移，第二时间段的终止时隙与第一时间段的起始时隙之间的偏移，第二时间段的起始时隙与第一时间段的终止时隙之间的偏移，第二时间段的终止时隙与第一时间段的终止时隙之间的偏移等。示例性的，如图8所示，第二预设时间段1的起始时隙与第一预设时间段1的起始时隙之间的偏移为OFFSET1，第二预设时间段1的结束时隙与第一预设时间段1的起始时隙之间的偏移为OFFSET2，第二预设时间段1的时间长度为WIDTH＝OFFSET2-OFFSET1。
本申请实施例中，第二指示信息的数量不限于一个。多个第二指示信息可以包括针对同一终端设备的第一指示信息，并且针对同一终端设备的第一指示信息在各个第二指示信息中的位置可以不必相同。当多个第二指示信息包括针对同一终端设备的第一指示信息时，需要根据第一信息确定第一指示信息在至少一个第二指示信息中的每一个第二指示信息中的位置。当一个终端设备在一个持续时间(ON duration)之前有X个第二指示信息时，可以有少于X个第二指示信息包括针对该终端设备的第一指示信息，或者，所有X个第二指示信息都包括针对该终端设备的第一指示信息。
可选的，所有第二指示信息中针对第一终端设备的第一指示信息的比特位被置位，则第一指示信息用于指示第一终端设备在预设时间内进入激活时间。如果任一个第二 指示信息中针对第一终端设备的第一指示信息的比特位未被置位，则第一终端设备不在预设时间内进入激活时间(即不会被唤醒)。
示例性的，如图9和图10所示，以第二指示信息有三个(第二指示信息1、第二指示信息2、第二指示信息3)，每个第二指示信息为8比特位的位图为例进行说明。
在图9中，部分第二指示信息包括针对同一终端设备的第一指示信息。第二指示信息1和第二指示信息2均包括针对终端设备1的第一指示信息以及终端设备2的第一指示信息，第二指示信息3包括针对终端设备3的第一指示信息。第二指示信息1和第二指示信息2中针对终端设备1的第一指示信息的比特位均置位，第二指示信息3中针对终端设备3的第一指示信息的比特位均置位，因此所有的第二指示信息最终指示终端设备1和终端设备3在各自对应的预设时间内进入激活时间。第二指示信息1针对终端设备2的第一指示信息的比特位置位，但是第二指示信息2针对终端设备2的第一指示信息的比特位未置位，因此，终端设备2不需要在预设时间内进入激活时间(即不会被唤醒)。
在图10中，多个第二指示信息全部包括针对同一终端设备的第一指示信息。第二指示信息1、第二指示信息2和第二指示信息3中针对终端设备1的第一指示信息的比特位均置位，因此所有的第二指示信息最终指示终端设备1在对应的时间内进入激活时间。第二指示信息1和第二指示信息3针对终端设备2的第一指示信息的比特位置位，但是第二指示信息2针对终端设备2的第一指示信息的比特位未置位，因此，终端设备2不需要在预设时间内进入激活时间(即不会被唤醒)。即只有在所有和终端设备相关联的第二指示信息中对应第一指示信息的比特位均置位的情况下，所述终端设备才需要在激活时间唤醒。
本申请实施例通过根据第一终端设备的标识信息和第一预设时间段的时间信息确定第一指示信息在至少一个第二指示信息中的位置，最终确定的位置会随着第一终端设备的标识信息以及第一预设时间段的时间信息的不同而改变，并且在不同第二指示信息中针对同一终端设备的第一指示信息的位置也可能不相同。以图9或图10为例，如果第一指示信息在第二指示信息中的位置固定不变，并且只有第二指示信息1，则会同时唤醒终端设备1和终端设备2，从而引起虚警。通过本申请实现位置的随机或伪随机分布，大大降低虚警的概率。
下面对如何根据第一信息确定第一指示信息在至少一个第二指示信息中的位置进行详细描述：
具体的，当待唤醒终端设备满足预设条件时，网络设备根据第一信息确定第一指示信息在第二指示信息中的位置。当待唤醒终端设备不满足预设条件时，网络设备根据待唤醒终端设备的配置信息确定第一指示信息在第二指示信息中的位置。
待唤醒终端设备满足预设条件，例如带唤醒终端设备的数量满足预设条件时，可以指待唤醒终端设备的数量大于预设阈值，待唤醒终端设备不满足预设条件，例如待唤醒终端设备的数量不满足预设条件，可以指待唤醒终端设备的数量小于或等于预设阈值。示例性的，预设阈值可以为第二指示信息的长度(例如位图的长度)。也就是说，当待唤醒终端设备的数量大于第二指示信息的长度时，存在多个终端设备共用同一位置的可能，通过位置的随机或伪随机分布来照顾所有终端设备的公平。当待唤醒 终端设备的数量小于第二指示信息的长度，可以采用固定位置来指示第一指示信息，可以避免虚警。
具体的，在一种可能的实施方式中，可以根据第一终端设备的标识信息和第一预设时间段的时间信息确定第一指示信息在至少一个第二指示信息中的位置。具体见公式1：
Y p,nt＝(A p*Y p,nt-1)modD      公式1
其中，A p为预设值，例如A p可以为一个质数，例如39827。nt为第一预设时间段的时间信息，例如，第一预设时间段的时隙(slot)编号、符号(symbol)编号、时隙内的CORESET的编号、第一预设时间段中唤醒信号监听机会的编号，或者，这些时间信息以任意方式组合计算后得到的一个值。D为单个第二指示信息的长度。Y p,nt为根据公式1得到的前一个Y p,nt-1进行迭代运算后得到的第一指示信息在至少一个第二指示信息中的位置，其中，该迭代运算的初始值Y p,-1等于第一终端设备的标识信息。
在另一种可能的实施方式中，可以根据第一终端设备的标识信息确定第一指示信息在至少一个第二指示信息中的位置。具体见公式2：
Y p,0＝(A p*Y p,-1)modD        公式2
其中，A p为预设值，例如A p可以为39827。D为单个第二指示信息的长度。Y p,-1等于第一终端设备的标识信息。Y p,0为得到的第一指示信息在至少一个第二指示信息中的位置。
在另一种可能的实施方式中，可以根据第一预设时间段的时间信息确定第一指示信息在至少一个第二指示信息中的位置。具体见公式3：
Y p,nt＝(A p*Y p,nt-1)modD      公式3
其中，A p为预设值，例如A p可以为一个质数，例如39827。nt为第一预设时间段的时间信息，例如，第一预设时间段的时隙(slot)编号、符号(symbol)编号、时隙内的CORESET的编号、第一预设时间段中唤醒信号监听机会的编号，或者，这些时间信息以任意方式组合计算后得到的一个值。D为单个第二指示信息的长度。Y p,nt为根据公式1得到的前一个Y p,nt-1进行迭代运算后得到的第一指示信息在至少一个第二指示信息中的位置，其中，该迭代运算的初始值Y p,-1为一常数。
进一步的，公式1-公式3中的A p还可以根据第一终端设备的分量载波组的标识(CC group ID)进行调整，即不同的分量载波组的标识，A p的取值也不同。
通过上述公式可以看出，当公式的输入改变时输出即发生改变，第一终端设备的标识信息和第一预设时间段的时间信息中的一个发生改变时，不同终端设备对应的第一指示信息的位置都可以不同，甚至在不同第二指示信息中的同一终端设备的第一指示信息的位置都可以不同，从而实现位置的随机或伪随机分布。
以上的映射方式仅是一个例子，本发明不失一般性，可以使用随机函数或者伪随机函数生成第一指示信息在第二指示信息中的比特位的位置。
可选的，如图11所示，步骤S701可以包括S7011-S7022：
S7011、第一终端设备向网络设备发送第一终端设备的支持能力。
相应地，网络设备可以从第一终端设备接收第一终端设备的支持能力。第一终端设备的支持能力指终端设备在根据第一信息确定第一指示信息在至少一个第二指示信息中的位置时，整个计算过程是否满足时延要求。
S7012、网络设备根据支持能力和第一信息确定第一指示信息在第二指示信息中的位置。
特别地，待唤醒终端设备满足预设条件时，网络设备根据支持能力和第一信息确定第一指示信息在第二指示信息中的位置。
如前面公式1-公式3所描述的，在根据第一信息确定第一指示信息在至少一个第二指示信息中的位置时需要进行迭代运算，如果第一终端设备的计算能力较弱，则不能根据第一信息确定第一指示信息在第二指示信息中的位置，只能采用固定位置的方式来指示第一指示信息。
对于如何根据第一信息确定第一指示信息在第二指示信息中的位置，见前面的相关描述，在此不再重复。
可选的，如图12所示，该方法还可以包括S1201:
S1201、网络设备向第一终端设备发送第三指示信息。
相应地，第一终端设备接收第三指示信息。
第三指示信息用于：指示第一终端设备根据第一信息确定第一指示信息在第二指示信息中的位置，即采用伪随机位置的方式来指示第一指示信息；或者，指示第一终端设备根据配置信息确定第一指示信息在第二指示信息中的位置，即采用固定位置的方式来指示第一指示信息。
也就是说，第三指示信息用于指示网络是否期望待唤醒终端设备使用第一信息确定第一指示信息在第二指示信息中的位置。作为一个例子，例如，第三指示信息用于指示待唤醒终端设备是否满足预设条件。当待唤醒终端设备满足预设条件时，指示第一终端设备根据第一信息确定第一指示信息在第二指示信息中的位置。当待唤醒终端设备不满足预设条件时，指示第一终端设备根据待唤醒终端设备的配置信息确定第一指示信息在第二指示信息中的位置。
可选的，第三指示信息可以承载在DCI的动态指示中或者针对第一终端设备的无线资源控制(radio resource control，RRC)消息中。
S702、网络设备在第一预设时间段对应的时频资源上发送第二指示信息。
也就是说，网络设备可以在WUS时机对应的时频资源上发送第二指示信息。
S703、第一终端设备根据第一信息确定第一指示信息在至少一个第二指示信息中的位置。
如前文所述的，在第一终端设备接收第三指示信息后，即可以确定按照哪种方式来确定第一指示信息在至少一个第二指示信息中的位置。即第一终端设备可以根据第一信息确定第一指示信息在第二指示信息中的位置，即采用伪随机位置的方式来指示第一指示信息；或者，第一终端设备可以根据配置信息确定第一指示信息在第二指示信息中的位置，即采用固定位置的方式来指示第一指示信息。
对于第一终端设备根据第一信息确定第一指示信息在至少一个第二指示信息中的位置，其方式与网络设备根据第一信息确定第一指示信息在至少一个第二指示信息中的位置的方式类似，具体见前面描述。
需要说明的是，步骤S703与步骤S702之间无先后执行顺序。并且，步骤S1201和步骤S702可以合并，即第三指示信息和第二指示信息可以是在同一时频资源或信令 中发送的。一种典型的例子为公共PDCCH-WUS。
S704、第一终端设备在第一预设时间段对应的时频资源上从网络设备接收第二指示信息。
也就是说，第一终端设备可以在WUS时机对应的时频资源上接收第二指示信息。需要说明的是，S1201也可以在S701之前，例如，所述第三指示信息承载在高层配置信令中时，网络会提前在S1201中配置并指示第三指示信息，之后网络采用S701发送第二指示信息。
本申请实施例提供的指示信息的发送方法，根据第一信息确定第一指示信息在至少一个第二指示信息中的位置，其中，所述第一信息包括第一终端设备的标识信息和第一预设时间段的时间信息中的至少一项，所述第一终端设备为处于不连续接收非激活时间的待唤醒终端设备中的一个，所述第一指示信息用于指示所述第一终端设备在预设时间内进入激活时间；所述第二指示信息用于指示至少一个所述待唤醒终端设备在对应的时间内进入激活时间。从中可以看出，第一终端设备的标识信息和第一预设时间段的时间信息中的一个发生改变时，不同终端设备对应的第一指示信息的位置都可以不同，甚至在不同第二指示信息中的同一终端设备的第一指示信息的位置都可以不同，从而实现位置的随机或伪随机分布。通过伪随机化各终端设备之间的WUS，以尽量做到所有终端设备的公平。
可以理解的是，以上各个实施例中，由第一终端设备实现的方法和/或步骤，也可以由可用于第一终端设备的部件(例如芯片或者电路)实现，由网络设备实现的方法和/或步骤，也可以由可用于网络设备的部件实现。
