本申请要求在2019年03月29日提交中国专利局、申请号为201910252162.7、申请名称为“一种下行控制信息的发送、处理方法及装置”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。
本申请涉及通信技术领域,尤其涉及一种下行控制信息的发送、处理方法及装置。
在新的无线技术NR(New Radio,新空口技术)***中,用户在连接态时,用户需要检测所有时隙中配置的物理下行控制信道(Physical Downlink Control Channel,PDCCH)检测机会(PDCCH monitor occasion),但是大多数PDCCH检测机会中,若基站没有发送PDCCH,这些PDCCH检测是没有必要的,用户进行PDCCH检测需要消耗功率,这些PDCCH检测将白白消耗终端能量。
在NR中,对长期演进(Long Term Evolution,LTE)***的连接态非连续接收(Connected Mode DRX,C-DRX)数据进行了统计,在大多数情况下LTE C-DRX周期内是没有数据的,如下面的表1所示。
表1基于LTE C-DRX对数数据的统计分析
应用 | 没有调度DRX周期占的比例 |
视频流 | 89% |
音频流 | 90% |
网页浏览 | 71% |
从表1中可以看出,对于大多数情况,DRX周期是没有数据调度。用户 会在DRX无线开启时进行PDCCH的检测。对于这些DRX周期可以令用户进入深度睡眠,当用户处于深度睡眠时,用户消耗的功率小于进行PDCCH检测功耗的百分之一。
由于每个DRX周期是否有数据调度是动态变化的,基站侧无法通过高层信令指示每个DRX周期内是否含有数据,基站可通过物理层的PDCCH或者信号指示DRX周期是否含有数据。对于每个用户来说,需要指示当前DRX是否需要进行PDCCH检测,一个PDCCH承载一个比特的数据会造成PDCCH资源的浪费。

可选地,所述节能信息可以针对不同用户分别配置。
本申请实施例中所述的用户,可以指终端,例如用户设备UE等。
可选地,所述group-common DCI包括M个用户或用户组,M为大于或等于1的正整数,每个用户组包含N个可变的比特(bit)位,N为大于或等于1的正整数。
可选地,所述比特位用于标识UE或UE组在所述比特位对应的时间内的节能信息。所述比特位对应的时间根据标准规定确定。
可选地,所述group-common DCI的格式通过至少一个无线网络临时标识(RNTI)加扰。
可选地,所述RNTI,是新定义的RNTI,或者是复用已有的RNTI。
可选地,所述已有的RNTI,是时隙格式指示无线网络临时标识SFI-RNTI;
所述SFI-RNTI指示的携带节能信息的DCI是SFI-DCI;
所述SFI-DCI,是基于SFI DCI保留比特位指示的,或者是基于SFI已用的比特位指示的。
所述基于SFI已用的比特位指示,当SFI指示为X时,表示用户在对应的时间频率单元上处于节能状态。
例如,在基站侧执行如下步骤:
步骤一:基站确定用户组和获取用户组内每个用户DRX周期上的调度信息;
具体如何分组以及如何调度用户,可以根据具体需要进行设置,本申请实施例不限制。
同一组的用户可以共用一个group-common PS-DCI。
同一组中的各个用户的DRX周期和DRX无线开启开始的时间可以不同,也可以相同。
步骤二:基站配置每个用户的承载PS-DCI的PDCCH参数,和/或PS-DCI所承载的指示参数,所述PS-DCI所承载的指示参数包括特定PDCCH检测机会,所述特定PDCCH可以指的是除PS-DCI之外的PDCCH,或者指的是包含PS-DCI的所有PDCCH,或者指的一类或几类PDCCH;或特定PDCCH的搜索空间和时频资源;和/或PS-DCI的组标识,所述PS-DCI的组标识可采用RNTI表示;和/或用户功率节省域对应比特和内容;
这里,用户功率节省域对应比特可以每个用户对应DCI中的一个比特,也可以每个用户对应了多个比特,每个用户对应了一个信息域或多个信息域,信息域可不同用户共享或者只针对一个用户即每个用户组包含N个可变的比特位,N为大于等于1的正整数,不同用户可以具有不同的N值。其中每个 比特的含义可以是标准预定义好的,或者可以通过高层信令配置每个用户功率节省比特所指示的含义。其中信息域可以指示用户是否醒来或睡去,以及醒来后频率域激活、时间域PDCCH检测的配置、以及空域波束管理相关内容。其中信息域还可以利用SFI来指示,在NR中,利用SFI指示时隙结构。本申请实施例利用SFI来指示唤醒或睡眠情况,对标准较少修改,达到省电的目的。

这里,所述承载PS-DCI的PDCCH参数,可以包括对承载PS-DCI的PDCCH资源和监视机会的配置。
步骤三:基站在所述承载PS-DCI的PDCCH资源上发送PS-DCI。
这里,可以配置在DRX无线开启(On)开始发送PS-DCI,或者在DRX关闭(OFF)的结束处发送PS-DCI,或者在DRX无线开启(radio-On)上周期发送,但当用户处于睡眠态时,用户不进行PS-DCI的接收。这里睡眠指的是DRX OFF,MAC CE指示用户睡眠,或者持续期(OnDuration)计数器到达设定值,使得用户进入睡眠,或者活跃态(InActivity)计数器达到设定值,使得用户进入睡眠状态。其中,DRX无线开启是DRX开启的一个状态,DRX开启状态有两种,一种是DRX无线开启,另一种是DRX开启,先进入DRX无线开启,目的是开启无线设备,然后进入DRX开启状态进行收发数据。
PS-DCI有可能是在DRX radio-On中发送,也可能在DRX off中发送,如果在DRX radio-On中发送就作用在当前DRX radio-On范围内,如果在DRXoff中发送,则作用在下一个DRX radio-On周期中。当PS-DCI在DRX OFF时,则PS-DCI指示了下一个DRX radio On的PDCCH检测和/或睡眠情况、和/或测量情况。
PS-DCI指示的信息中还可以包含用于指示需要检测PDCCH的位置相对当前PS-DCI位置的时间偏移的信息,但这种方法不应影响OnDuration计数器的开始时间。
当一个DRX无线开启周期中含有多个PS-DCI周期时,在每个PS-DCI周期,OnDuration计数器和InActivity计数器不应被重置。
PS-DCI还可以包含用于指示对PDCCH检测机会进行选择的信息,用以指示在原有高层配置的检测机会上进一步选择PDCCH检测机会。PDCCH检测机会指的是用户只有在检测机会上进行PDCCH检测。可以通过比特映射方式指示,比特映射指的是每个用户/全部用户/部分用户有1个或多个专属比特指示其功率节约的信息;或者预先设定一个表格,列出各种PDCCH检测机会的图样,基站向终端指示图样在表格中的序号,使得终端可以根据预设表格,确定该序号所对应的图样,从而进一步确定需要选择的PDCCH检测机会。
相应地,在终端侧,参见图2,本申请实施例提供的一种下行控制信息处理方法,包括:

可选地,所述节能信息包括下列内容之一或组合:
是否醒来监测物理下行控制信道PDCCH;

是否切换带宽部分BWP;
是否激活或去激活载波;
是否配置休眠辅小区;
是否配置DRX参数集合;
是否配置PDCCH解码节能信息;
是否配置无线资源管理RRM节能功能;
是否触发参考信号发送和/或相关测量信息上报。
除了上述信息,节能信息还可以用于指示其他类型的节能信息,在此不在赘述。
可选地,所述group-common DCI包括M个用户或用户组,M为大于或等于1的正整数,每个用户组包含N个比特位,N为大于或等于1的正整数。
可选地,所述比特位用于标识UE或UE组在所述比特位对应的时间内的节能信息。所述比特位对应的时间根据标准规定确定。
可选地,所述group-common DCI的格式通过至少一个无线网络临时标识RNTI加扰。
可选地,所述RNTI,是新定义的RNTI,或者是复用已有的RNTI。
可选地,所述已有的RNTI,是时隙格式指示无线网络临时标识SFI-RNTI;
所述SFI-RNTI指示的携带节能信息的DCI是SFI-DCI;
所述SFI-DCI,是基于SFI DCI保留比特位指示的,或者是基于SFI已用的比特位指示的。
例如,终端侧执行下列步骤:
步骤一:终端接收基站配置的承载PS-DCI的PDCCH参数,进一步终端根据承载PS-DCI的PDCCH参数接收并检测PS-DCI,并获取PDCCH检测机会、搜索空间和时频资源,和/或PS-DCI的组识别标识,例如对应的RNTI,和/或用户对应PS-DCI的域对应比特,和/或当前PS-DCI的作用范围;
这里,PS-DCI的作用范围可以是高层指示,或者PS-DCI作用在DRX On中非睡眠的状态下,或者PS-DCI作用在当前PS-DCI周期。
步骤二:用户根据PS-DCI PDCCH参数,在对应的作用域判断是否需要进行PDCCH检测;
这里,任意一组中的各个用户DRX周期不同时,如果PS-DCI在每个DRX开始发送,每个用户只需要按照自己的PS-DCI配置接收PS-DCI,并且根据PS-DCI确定是否需要进行PDCCH检测。当用户接收到PS-DCI指示用户不进行PDCCH检测,则用户在收到该PS-DCI之后,在该PS-DCI作用的范围内,不再进行PS-DCI的检测。或者当用户接收到PS-DCI指示用户进入睡眠, 则用户在收到该PS-DCI之后,进入睡眠,直到下一个DRX周期。或者当用户接收到PS-DCI指示用户进行PDCCH检测,则用户在收到该PS-DCI之后,按照DRX的时序进行PDCCH检测。
当PS-DCI在DRX OFF时,则PS-DCI指示了下一个DRX On的PDCCH检测和睡眠情况,当PS-DCI在DRX OFF时,则PS-DCI指示了下一个DRX On的PDCCH检测和睡眠情况。

以SFI-RNTI为例,可以采用SFI标识用户组的节能信息。具体的,在NR中,会用PDCCH指示时隙结构,可参考38.211。当符号为X时,该符号传输方向为灵活方向,用户不在这个符号上进行PDCCH接收和下行测量。基于组的PS-DCI也可以利用该DCI格式,将不需要检测和/或测量的符号配置为灵活符号。如果group common DCI是用来指示功耗节省时,当用户收到该PS-DCI时,如果配置的时隙结构中不含有下行符号,用户可以在DRX On周期进入睡眠状态,或者仅仅不进行下行PDCCH检测和/或测量,还是会按照指示时隙结构的group common DCI指示进行上行发送和反馈。具体睡眠或者进行测量或上行传输可以通过高层配置。
PS-DCI和指示时隙结构的DCI可以分开配置,也可以联合配置。当PS-DCI和指示时隙结构的DCI的联合配置时,该DCI在特定的时间,和/或配置成为特定值时,用户会有不同于按照指示时隙结构DCI的处理方式。比如该DCI指示时隙中不含有下行符号,用户可以在收到该信令后的DRX On周期进入睡眠状态,或者仅仅不进行下行PDCCH检测,还是会按照时隙结构 的DCI指示进行测量和上行发送和反馈。具体睡眠或者进行测量和上行传输可以通过高层配置。
每个用户有8个比特指示了时隙结构,还有两个比特未使用,这两个比特可以指示带宽部分(BandWidth Part,BWP)的激活情况,或者PDCCH搜索空间的降低。
PS-DCI和指示时隙结构的DCI可以统一配置。当该DCI在特定位置,比如DRX On的开始或者DRX Off的结束时,那两个未使用的比特可以用作约定用途。(否则忽略这两个比特。)
以SFI-RNTI为例,还可以采用SFI中reserved的两个比特指示的index标识用户组的节能信息。具体的:
以index=56~60为例,指示的PDCCH检测的位置如下表5所示,其他index标识和监测PDCCH检测机会的位置的标识,不做限定。
表5 SFI信息域指示示例
以上表5中,在SFI index56~255中,X,U可以表示跳过监测PDCCH,D、X可以表示监测PDCCH;其他的指示方法,本文不再赘述。
以SFI-RNTI为例,还可以采用SFI中0~55index的比特域重新解释来标识用户组的节能信息。具体的:
所述比特域重新解释,可以用X、U表示跳过监测PDCCH,DX可以表示监测PDCCH;其他的指示方法,本文不再赘述;
