目标小区搜索空间集组的切换及其控制方法及装置
相关申请的交叉引用
本申请要求在2021年01月18日提交中国专利局、申请号为202110060710.3、申请名称为“目标小区搜索空间集组的切换及其控制方法及装置”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，尤其涉及目标小区搜索空间集组的切换及其控制方法及装置。
背景技术
基站会通过系统消息为用户分配一个或多个搜索空间(search space)，每个搜索空间的配置是周期性的，用户在配置的搜索空间进行物理下行控制信道(Physical Downlink Control Channel，PDCCH)检测。用户每次进行PDCCH检测的时刻称为PDCCH监听机会(PDCCH monitoring occasion)。搜索空间一般是周期性配置。在5G NR系统中，终端(User Equipment，UE)为了获得下行调度信息，需要在每个PDCCH监听机会对PDCCH进行监听，来判断是否有下行调度信息。每次PDCCH监听的过程都是一次PDCCH译码过程，然后根据循环冗余校验(Cyclic Redundancy Check，CRC)校验结果判断为携带UE调度信息的下行控制信息(Downlink Control Information，DCI)。如果PDCCH有用户的调度信息，那么UE可以获得正的CRC校验，同时，可以获得DCI中携带的调度信息；否则，CRC校验为负值，UE无法获得DCI中的任何信息。
PDCCH监听信息主要由搜索空间集配置，但现有的搜索空间集组切换过程不是针对不同用户的业务特征的搜索空间集组切换，因此导致终端传输性能以及终端节能较差。

这里，目标搜索空间集组是高层信令配置的两个或两个以上搜索空间集组中的任意一个。
步骤四：终端侧接收到基站下发的切换指示后，将目标小区或目标小区组的当前搜索空间集组切换至目标搜索空间集组。
这里，目标小区或目标小区组可以是服务小区或主小区或辅小区或辅小区组中的一个或多个小区。目标搜索空间集组是高层信令配置的两个或两个 以上搜索空间集组中的任意一个。
关于搜索空间集组切换(Search Space set group switching)过程介绍如下：
当UE能力指示UE是否支持两种搜索空间集组切换方式中的至少一种：searchSpaceSetGroupSwitchingwithoutDCI-r16和/或searchSpaceSetGroupSwitchingwithDCI-r16。如果基站(gNB)根据UE能力给UE配置搜索空间集组列表searchSpaceGroupIdList-r16，用于指示哪个或哪些服务小区进行搜索空间集组切换过程，则进行搜索空间集组切换过程；否则，UE不会进行搜索空间集组切换过程。如果UE被配置了searchSpaceGroupIdList-r16且同时配置了searchSpaceGroupIdList-r16指示了相应的搜索空间集，则UE根据搜索空间集组0重配置搜索集并进行相应的PDCCH监听。
搜索空间集分组仅针对Type-3 CSS和USS搜索空间集。当搜索空间集没有配置搜索空间集组索引时，则终端需要一直监听该搜索空间集。
搜索空间集组切换指示有两种方式：显示指示和隐式指示，通过RRC信令是否配置SearchSpaceSwitchTrigger-r16进行区分。如果配置了，则为显示指示；否则，为隐式指示。
对于显式指示是通过DCI格式2_0中的搜索空间集组切换触发指示进行搜索空间集组0与搜索空间集组1的切换触发。此外，基站还会通过RRC信令配置搜索空间集组切换计时器searchSpaceSwitchingTimer-r16，当其倒计时超时时，或UE被配置的DCI格式2_0的搜索空间中携带的剩余信道占用时间(remaining channel occupancy duration)的最后一个符号之后，UE会回退至默认的搜索空间集组的监听，其中，搜索空间集组0是默认的搜索空间集组。计时器searchSpaceSwitchingTimer-r16是在UE切换至搜索空间集组1开启。UE在搜索空间集组0和搜索空间集组1之间切换时，会有一定时延，根据UE能力分为能力1和能力2，由gNB根据UE能力通过高层信令进行配置。
表1.切换时延P switch的最小值[符号]
μ UE处理能力1[符号] UE处理能力2[符号]
  25 10
  25 12
  25 22
对于隐式指示是通过UE是否检测到相应的搜索空间集组的DCI格式触发搜索空间集组切换。如果UE检测到了搜索空间集组0中配置的DCI，则UE开始进行搜索空间集组1的配置进行PDCCH监听，并停止搜索空间集组0中的PDCCH监听，当检测到搜索空间集组1中任意DCI则开启计时器searchSpaceSwitchingTimer-r16。当计时器倒计时超时时，或UE被配置的DCI格式2_0的搜索空间中携带的剩余信道占用时间(remaining channel occupancy duration)的最后一个符号之后，UE从搜索空间集组1切换回搜索空间集组0。同显示指示一样，在搜索空间集组0和搜索空间集组1之间切换时，会有一定时延，根据UE能力分为能力1和能力2，由gNB根据UE能力通过高层信令进行配置。
本搜索空间集组切换在NR-U议题下讨论的初衷是，通过搜索空间集组切换的方式在令终端在基站抢占非授权频带时快速接收到PDCCH，通常情况下用户在COT之前的PDCCH的监听比较频密，可以快速监听到PDCCH，即基站一旦抢占到非授机频段，UE能够尽快开始数据传输。而当终端处于COT时，PDCCH监听周期较大，终端可以一定程度上减少盲栓，实现终端节能。
DCI格式2_0的信息域内容：
当DCI格式2_0的CRC由SFI-RNTI加扰时，其信息域的具体内容包括以下内容：
如果高层信令配置了参数搜索空间切换触发列表(searchSpaceSwitchTriggerToAddModList-r16)，则DCI格式2_0中相关的搜 索空间集组切换信息域包括以下：
搜索空间集组切换指示1，搜索空间集组切换指示2，……，搜索空间集组切换指示M。
每个指示用于对终端所配置的一个辅小区或辅小区组的搜索空间集组切换进行指示。
下面给出几个具体实施例的举例说明。
实施例一：具体的搜索空间集组切换过程举例。
步骤一：终端侧向基站上报其用户能力，是否支持用于终端节能的搜索空间集组切换。
该用户能力可以是节能专属的搜索空间集组切换能力，也可以是现有搜索空间集组切换能力的版本升级或扩展。
步骤二：基站侧为终端配置节能相关的搜索空间集组。这里，搜索空间集分组可以隶属于服务小区或主小区或辅小区或辅小区组中的一个或多个小区。搜索空间集组可以是两个或两个以上。
以下内容仅用于举例说明：
对于基站侧配置了两个搜索空间集组，其中一个搜索空间集组作为默认的搜索空间集组，另一个作为候选搜索空间集组，如，默认的搜索空间集组可以作为终端进行监听常规的PDCCH的搜索空间集配置，另一个用于节能目的的搜索空间集组。搜索空间集组可以只关联主小区，即只对主小区的搜索空间集进分组，相应的搜索空间集组的索引为0或1；同理，也可以关联某个或某几个小区，也可以关联某个或某几个小区组，即对某个或某几个小区(小区组)下的搜索空间集进行分组，分组的索引值为0或1，这里的小区包括主小区和/或辅小区，小区下的搜索空间集可以全部参与分组，也可以部分参与分组。
对于基站侧配置了多个搜索空间集组，其中一个搜索空间集组为默认的搜索空间集组，可以通过高层信令预配置；也可以固定为某个索引值，如索引0；其余的作为候选搜索空间集组，并配置相应的分组索引值，如，该默认 搜索空间集组可以作为终端进行监听常规的PDCCH的搜索空间集配置，其他搜索空间集组作为节能目的的搜索空间集组候选，通过下行控制信令进行具体指示切换至哪一个目标搜索空间集组。
当终端在初始接收到基站侧对搜索空间集组配置时，可以按默认搜索空间集组进行PDCCH监听，也可以维持在现有搜索空间集组进行PDCCH监听。
步骤三：基站通过携带用户专属指示的下行控制信令向终端侧发送搜索空间集组切换指示，用于指示终端将目标小区或目标小区组切换至目标搜索空间集组。
这里，目标小区或目标小区组可以是服务小区或主小区或辅小区或辅小区组中的一个或多个小区。
这里，携带用户专属指示的下行控制信令，不局限于一种信令，包括多种内容的一种或多种的组合：
一、进行搜索空间集组切换的目标小区指示信息或目标小区组指示信息。
如果搜索空间集组切换只针对于固定的某个小区，如：主小区或当前服务小区或这两个小区所在的小区组，则本信息可以缺省。
这里，目标小区或目标小区组指示信息可以通过显式指示，也可以通过隐式指示。目标小区或目标小区组指示信息可以是小区(组)的ID，也可以是目标小区(组)列表的索引指示或是列表的比特映射指示。目标小区或目标小区组指示信息可以通过高层信令进行配置，也可以通过DCI格式携带，也可以通过MAC CE进行指示，也可以是高层信令和DCI格式/MAC CE的组合指示。
二、搜索空间集组切换指示，1～N比特。
搜索空间集组切换指示可以通过DCI格式和/或MAC CE和/或RRC专属信令进行指示，具体指示方法详见实施例二。
携带搜索空间集组切换指示的DCI可以是携带调度信息的DCI格式0_1/1_1(可参见实施例二)，也可以是携带非调度信息的DCI格式0_1/1_1(可参见实施例三)，也可以是DCI格式2_6(可参见实施例四)，也可以是DCI 格式0_2/1_2，不限制于所列多种。
三、目标搜索空间集组指示信息。
这里，目标搜索空间集组信息可以通过显式指示，也可以通过隐式指示。例如：显式指示可以是目标搜索空间集组的ID，也可以是高层信令配置的列表所对应的索引值。隐式指示可以通过是搜索空间组切换指示域进行比特映射，也可以是MAC CE进行目标搜索空间集组列表比特映射指示，也可以是高层信令配置。
这里，目标搜索空间集组是高层信令配置的两个或两个以上搜索空间集组中的任意一个。这里目标搜索空间集组可以与终端当前所在搜索空间集组相同，也可以不同。
步骤四：终端侧接收到基站发送的携带用户专属指示的下行控制信令后，根据其中所携带的搜索空间集组切换信息，将其指示的目标小区或目标小区组切换至目标搜索空间集组进行相应的PDCCH监听。
可选地，基站侧为了保证终端能够从节能模式回退至常规的PDCCH监听模式，避免因没有及时收到携带切换指示的下行控制信令而影响终端正常的数据接收，搜索空间集组切换过程也可以采取回退机制，具体可以为以下一种或多种的组合：
方法一：配置回退定时器。当定时器超时时，终端回退至默认搜索空间集组。
方法二：如果终端配置了DRX机制，在下一个DRX周期，如长DRX周期和/或短DRX周期的起始位置，终端回退至默认搜索空间集组。如果节能信号指示下一个DRX周期不开启激活期定时器，则终端可以在下一个DRX周期回退至默认搜索空间集组，也可以在后续被唤醒的DRX周期回退至默认搜索空间集组。
其中，关于DRX传输，介绍如下：
当UE配置了DRX，UE将不连续的监听PDCCH。UE只在DRX激活期间，例如：激活期定时器(on duration timer)或非激活定时器(Inactivity timer) 等未超时时，进行PDCCH监听。
DRX(Discontinuous Reception非连续接收)机制如图1所示。在DRX周期内，UE只在激活期内监测PDCCH，在DRX非激活期，即DRX off时间内，UE不接收除调度广播信令之外的其他PDCCH以减少功耗，即进入睡眠模式。
实施例二：搜索空间集组切换指示域：1～N比特，N为大于等于1的整数。
对于搜索空间集组切换指示域可以采用1比特或多个比特，具体举例如下：
对于搜索空间集组切换指示域只有1个比特，且高层信令只配置了两个搜索空间集组，则该比特指示表示目标小区或目标小区组的搜索空间集组切换指示。
例如：取值为“1”表示从搜索空间集组0切换至搜索空间集组1进行PDCCH监听，或维持在搜索空间集组1进行PDCCH监听；取值为“0”表示从搜索空间集组1切换至搜索空间集组0进行PDCCH监听，或维持在搜索空间集组0进行PDCCH监听。
又例如：取值为“1”表示搜索空间集组发生变化，即从当前搜索空间集切换至另一个搜索空间集进行PDCCH监听；取值为“0”表示搜索空间集组不发生变化，维持当前的搜索空间集组进行PDCCH监听。
对于搜索空间集组切换指示域只有1个比特，且高层信令只配置了多个搜索空间集组，则该比特指示表示目标小区或目标小区组的搜索空间集组切换指示。
例如：取值为“1”表示从搜索空间集组0切换至目标候选搜索空间集组进行PDCCH监听，或维持在目标候选搜索空间集组进行PDCCH监听；取值为“0”表示从目标候选搜索空间集组切换至搜索空间集组0进行PDCCH监听，或维持在搜索空间集组0进行PDCCH监听。
又例如：取值为“1”表示搜索空间集组发生变化，即从当前搜索空间集 组切换至目标候选搜索空间集组或默认搜索空间集组进行PDCCH监听；取值为“0”表示搜索空间集组不发生变化，维持当前的搜索空间集组进行PDCCH监听。
目标候选搜索空间集组可以通过高层信令进行指示，也可以通过MAC CE指示。例如：高层信令配置了M个搜索空间集组，MAC CE可以通过M比特进行比特映射的方法具体指示目标候选搜索空间集组。
对于搜索空间集组切换指示域只有N个比特，且高层信令只配置了M个搜索空间集组，则该N比特指示表示目标小区或目标小区组的特定的搜索空间集组切换指示。指示方法可以是具体的搜索空间集组具体索引，或是高层信令配置的搜索空间集组列表的索引值。不限于上述所例多种。
对于搜索空间集组切换指示域只有N个比特，且高层信令只配置了M个搜索空间集组，则该搜索空间集组切换指示域中的每个比特指示一个目标小区或目标小区组的搜索空间集组切换指示。具体如上所述。这里，N大于等于M，且皆为整数。
注：这里的搜索空间集组切换指示域是指用户专属的切换指示(即用户专属指示)，并非控制信令中携带的所有搜索空间集切换相关的切换指示信息的集合，例如不包括进行搜索空间集组切换的目标小区信息或目标小区组指示信息、目标搜索空间集组指示信息等。
实施例三：携带用户专属指示的下行控制信令的设计方法——携带调度信息的DCI格式0_1/1_1。
为了减少DCI信令的开销，本实施例仅通过DCI格式携带搜索空间集组切换指示，其他信息可以通过高层信令进行预配置，和/或MAC CE进行指示。
在携带调度信息的DCI格式0_1/1_1中用于搜索空间集组切换指示的方法有以下一种或多种的组合：
方法一：在DCI格式0_1/1_1增加1～N比特的信息域，用于指示搜索空间集组切换，具体指示方法详见实施例二。
方法二：现有下行控制信令中重新定义已有的信息域用于节能的搜索空 间集组切换。例如：当CIF域不为0时，辅小区(SCell)休眠指示域可以作为搜索空间集组切换指示和/或SCell(SCell组)休眠指示；当CIF域为0时，SCell休眠指示域可以用于SCell(SCell组)的休眠行为指示。
以下举例说明一种方法一的使用方法，但不限于举例说明：
假设基站通过高层信令给终端的主小区配置了两个搜索空间集组，索引值分别是“0”和“1”，每个搜索空间集组包括一个或多个搜索空间集。搜索空间集组0是默认搜索空间集组，搜索空间集组1是PDCCH监听周期较稀疏的搜索空间集的分组。
基站通过携带调度信息的DCI格式0_1/1_1给终端发送搜索空间集组切换的相关信息。当基站调度最后一个数据包时，可以通过携带调度信息的DCI格式0_1/1_1中的搜索空间集组切换指示域(以1比特为例)取值为“1”，指示终端的主小区切换至搜索空间集组1进行较稀疏的PDCCH监听；反之，当终端有数据待传输时，基站侧通过携带调度信息的DCI格式0_1/1_1给终端发送数据调度的相关信息的同时，将搜索空间集组切换指示域(以1比特为例)设置为“0”，指示终端回退至搜索空间集组0进行常规的PDCCH监听。
以下举例说明一种方法二的使用方法，但不限于举例说明：
假设基站通过高层信令给终端的主小区配置了两个搜索空间集组，索引值分别是“0”和“1”，每个搜索空间集组包括一个或多个搜索空间集。搜索空间集组0是默认搜索空间集组，搜索空间集组1是PDCCH监听周期较稀疏的搜索空间集的分组。
当基站通过携带调度信息的DCI格式0_1/1_1给终端发送搜索空间集组切换的相关信息，同时，终端支持跨载波调度。当基站在调度最后一个数据包时，在携带调度信息的DCI格式0_1/1_1中配置CIF为非零值，且将仅SCell休眠指示域配置1比特作为搜索空间集组切换指示，取值为“1”时，指示终端的主小区切换至搜索空间集组1进行较稀疏的PDCCH监听；反之，当终端有数据待传输时，基站侧在携带调度信息的DCI格式0_1/1_1中配置CIF为非零值，且将仅SCell休眠指示域配置1比特作为搜索空间集组切换指示，取 值为“0”时，指示终端回退至搜索空间集组0进行常规的PDCCH监听。
此外，在携带调度信息的DCI格式0_1/1_1中配置CIF为非零值时，SCell休眠指示域可以配置为搜索空间集组切换指示与SCell休眠指示域的联合指示，例如：该指示域值是联合指示列表的索引值或编码值，或者1比特+(N-1)比特SCell休眠指示，N比特是SCell休眠指示域的总长度。不限所罗列多种。
携带调度信息的DCI格式0_2/1_2的设计方法与携带调度信息的DCI格式0_1/1_1一致，不再赘述。
实施例四：携带用户专属指示的下行控制信令的设计方法——携带非调度信息的DCI格式0_1/1_1。
为了减少DCI信令的开销，本实施例仅通过DCI格式携带搜索空间集组切换指示，其他信息可以通过高层信令进行预配置，和/或MAC CE进行指示。
在携带非调度信息的DCI格式0_1/1_1中用于搜索空间集组切换指示的方法有以下一种或多种的组合：
方法一：在DCI格式0_1/1_1中增加1～N比特的信息域，用于指示搜索空间集组切换，具体指示方法详见实施例二。
方法二：现有下行控制信令中重新定义已有的信息域用于节能的搜索空间集组切换，包括以下信息域的一个或几个的组合：调制编码方案信息域(modulation and coding scheme)、新的数据指示域(new data indicator)、冗余版本信息域(redundancy version)、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程号域(HARQ process number)、天线端口域(antenna port(s))、解调参考信号(Demodulation Reference Signal，DMRS)序列初始化域(DMRS sequence initialization)等，最多14比特信息域中的1～N比特用于搜索空间集组切换指示。具体地，当以下条件同时满足时：短HARQ-ACK请求域中为缺省或为“0”值，载波指示域缺省或取值为“0”以及资源分配指示域为全“0”值或全“1”值，上述所列的信息域中任意1～N个比特可以单独用于搜索空间切换集组切换，也可以上述所列的信息域中信息比特用于搜索空间集组切换和辅小区休眠指示的联合指示。
以下举例说明，但不限制于所举示例：
注：上述信息域是指调制编码方案信息域(modulation and coding scheme)、新的数据指示域(new data indicator)、冗余版本信息域(redundancy version)、HARQ进程号域(HARQ process number)、天线端口域(antenna port(s))、DMRS序列初始化域(DMRS sequence initialization)等信息域。
方法一：(单独指示)对于非调度DCI中的上述信息域中设定一个指示信息，如1比特，当其取值为“0”时，上述信息域除指示信息之外均可用于搜索空间集组切换的指示信息域；当其取值为“1”时，上述信息域可以用于SCell或SCell组休眠指示域。
方法二：(联合指示)对于非调度DCI中的上述信息域中可以同时用于搜索空间集组切换以及SCell或SCell组的休眠指示，具体的信息域的位置可以通过高层信令进行配置。
当终端无数据传输时，基站侧可以通过非调度信息的DCI格式0_1/1_1用于通知终端在目标小区(组)进行相应的搜索空间集组切换触发。
携带非调度信息的DCI格式0_2/1_2的设计方法与携带非调度信息的DCI格式0_1/1_1一致，不再赘述。
实施例五：携带用户专属指示的下行控制信令的设计方法——DCI格式2_6。
为了减少DCI信令的开销，本实施例仅通过DCI格式携带搜索空间集组切换指示，其他信息可以通过高层信令进行预配置，和/或MAC CE进行指示。
在DCI格式2_6中用于搜索空间集组切换指示的方法有以下一种或多种的组合：
方法一：基站在DRX非激活期发送DCI格式2_6，在DCI格式2_6每个用户的信息域中增加1～N比特的信息域，用于指示某个用户接下来的DRX周期的激活期的搜索空间集组切换情况。例如：如果终端接收到的DCI格式2_6中的搜索空间集组切换指示为“1”，则在目标小区中的接下来的DRX周期内切换至搜索空间集组1进行稀疏的PDCCH监听，以实现终端节电的目的。又 或者，在终端接收到的DCI格式2_6中的搜索空间集组切换指示为“1”，则在目标小区中的接下来的DRX周期内切换至搜索空间集组1进行稠密的PDCCH监听，以提升终端传输时延性能。
方法二：基站在DRX激活期发送DCI格式2_6，将DCI格式2_6的唤醒指示域重定义为搜索空间集组切换指示域。
当基站在DRX非激活期发送DCI格式2_6时，每个用户的信息域为唤醒指示域+SCell休眠指示域；当基站在DRX激活期发送DCI格式2_6时，每个用户的信息域为搜索空间集组切换指示域+SCell休眠指示域。其中，1比特的搜索空间集切换指示域的使用方法，可参见实施例二。基站在DRX激活期内通过DCI格式2_6对终端的搜索空间集组的切换进行指示，从而实现终端节能的效果。
实施例六：携带用户专属指示的下行控制信令的设计方法——DCI格式2_0。
为了减少DCI信令的开销，本实施例仅通过DCI格式携带搜索空间集组切换指示，其他信息可以通过高层信令进行预配置，和/或MAC CE进行指示。
当基站侧配置的DCI格式2_0中搜索空间集组切换指示域的比特数M大于终端配置的目标小区或目标小区组的个数N，则可以实现用户专属切换指示。
举例说明：
当终端进行搜索空间集组切换的目标小区(组)只有一个且搜索空间集组为2时，DCI格式2_0中搜索空间集组切换指示域的只需要2比特，如“01”，根据高层信令配置信息，只需给接收DCI格式2_0的K个终端配置目标小区(组)ID以及搜索空间集组切换指示在DCI格式2_0中的位置，即可实现不同终端不同的搜索空间集组切换结果。如用户1，2，3指示“0”的位置，用户4，5，6指示“1”的位置。当终端的搜索空间集发生改变时，需要通过RRC重配置指示新的位置，或者通过MAC CE进行指示。
当终端进行搜索空间集组切换的目标小区(组)有2个且搜索空间集组 有2个时，DCI格式2_0中搜索空间集组切换指示域的只需要3比特，如“101”，对应的DCI格式中的位置分别为P1,P2,P3，根据高层信令配置信息，只需接收给接收DCI格式2_0的K个终端配置目标小区(组)ID以及搜索空间集组切换指示在DCI格式2_0中的位置，即可实现不同终端不同的搜索空间集组切换结果。如用户1的两个目标小区(组)分别为P1和P2,用户2的两个目标小区(组)分别为P2和P3,用户3的两个目标小区(组)分别为P1和P3，等。
此外，也可以在DCI格式2_0中采用比特映射的方式，实现接收DCI格式2_0的一组用户的不同切换情况。如每个终端配置了两个搜索空间集组，索引分别为0或1，同时，接收DCI格式2_0的用户有K个，则DCI格式2_0中的搜索空间集组切换指示域为K比特，每个比特对应一个终端的搜索空间集组的切换情况。
实施例七：携带调度信息的DCI与非调度DCI之间的联合使用。
用户可以同时支持两种或两种以上的DCI进行用户专属指示的搜索空间集切换，具体的DCI格式设计详见实施例二至实施例六。
例如：用户同时支持携带调度信息的DCI格式0_1/1_1以及非调度信息的DCI格式0_1/1_1，用于携带用户专属指示。当用户在数据传输最后一个数据包时，基站侧可以通过发携带调度信息的DCI格式用于指示用户进行搜索空间集切换至较为节能的搜索空间集，如：监听周期较大，聚合等级配置的子集等(不局限于所列)。当用户处于无数据调度且同时处于DRX激活期时，基站侧可以通过发送非携带调度信息的DCI格式0_1/1_1指示用户进行搜索空间集切换至更为节能的搜索空间集，进行进一步的终端节能；或恢复默认的搜索空间集，以准备后续的数据业务的接收。
又例如：用户同时支持携带调度信息的DCI格式0_1/1_1以及非调度信息的DCI格式2_6，用于携带用户专属指示。当用户在数据传输最后一个数据包时，基站侧可以通过发携带调度信息的DCI格式用于指示用户进行搜索空间集切换至较为节能的搜索空间集，如：监听周期较大，聚合等级配置的 子集等(不局限于所列)。当用户处于无数据调度且处于DRX非激活期时，基站侧可以通过发送非携带调度信息的DCI格式2_6，指示用户在后续唤醒的DRX激活期内进行搜索空间集切换至更为节能的搜索空间集，进行进一步的终端节能；或恢复默认的搜索空间集，以准备后续的数据业务的接收。
注：以上仅为不同类型的DCI联合使用的示例，并不局限于上述所列的情况。所述用户，即终端。
