Description

一种PDCCH监听及发送方法、装置、终端设备、网络设备 技术领域
本申请实施例涉及移动通信技术领域,具体涉及一种物理下行控制信道(Physical Downlink Control Channel,PDCCH)监听及发送方法、装置、终端设备、网络设备。
背景技术
业务数据传输具有一定的刷新频率(简称为刷新率),刷新率是指单位时间内传输的业务数据帧的个数。与刷新率对应的一个概念是周期,周期等于刷新率的倒数。
终端设备为了接收周期性的业务数据,需要在PDCCH搜索空间集(PDCCH search space set)中的PDCCH监听时机(PDCCH monitoring occasion)上监听PDCCH,基于监听到的PDCCH中携带的调度信息去接收业务数据。然而,目前的PDCCH搜索空间集的周期的取值是固定且有限的,PDCCH搜索空间集的周期和业务数据的传输周期可能会出现不匹配的情况,这将导致终端设备无法正常接收业务数据。

为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
AR/VR业务
随着移动互联网的快速发展,增强现实(Augmented reality,AR)技术和虚拟现实(Virtual Reality,VR)技术蓬勃发展。为了满足AR技术和VR技术的需求,移动通信网络需要提供大带宽,低延迟的通信服务。
对于AR业务和VR业务来说,为了提升用户体验,业务数据传输需要较高的刷新率,一般60Hz以上的刷新率可以带来较佳的用户体验,典型的刷新率的取值为60Hz,90Hz,120Hz,180Hz等。与刷新率对应的一个概念是周期,可以理解,对于AR业务和VR业务来说,业务数据传输具有一定的周期性,业务数据传输的刷新率为60Hz时,对应的传输周期为16.67ms,如图2所示。
终端设备在支持高速率低时延的同时需要消耗较大的电量,如何在满足业务数据传输需求的同时降低终端设备的电量消耗是需要考虑的问题。
NR中PDCCH搜索空间
终端设备在PDCCH搜索空间集中的PDCCH时机上进行PDCCH监听。这里,PDCCH搜索空间集由周期性的PDCCH搜索空间组成。PDCCH搜索空间集一般由网络设备通过RRC信令配置给终端设备。作为示例,PDCCH搜索空间集的配置信息包括以 下至少一种信息:
搜索标识(search ID):用于指示PDCCH搜索空间集的标识;
控制资源集标识(controlResourceSetId):用于指示控制资源集的配置的标识,这里,控制资源集的配置用于配置PDCCH搜索空间集的时频资源;
PDCCH搜索空间集的周期:用于指示PDCCH搜索空间集中相邻两个PDCCH搜索空间的时隙个数,NR支持的周期的取值有:1、2、4、5、8、10、16、20、40、80、160、320、640、1280、2560,单位为时隙。
PDCCH搜索空间集在周期内的偏置:用于指示PDCCH搜索空间集的第一个PDCCH搜索空间的起始位置所在的时隙相对于周期的起始时隙的时隙差;
PDCCH搜索空间集的监听时长(Duration):用于指示在PDCCH搜索空间集中的每个PDCCH搜索空间上连续监听的时隙个数;
PDCCH搜索空间集的监听符号(monitoringSymbolsWithinSlot):用于指示监听时隙内的一个或多个监听位置的起始符号;
PDCCH搜索空间集对应的PDCCH候选(PDCCH candidates):用于指示PDCCH candidate的配置信息;
PDCCH搜索空间集的类型:用于指示PDCCH搜索空间集是公共搜索空间集还是UE专属搜索空间集。
对于AR业务和VR业务来说,为了匹配周期性的业务传输特点,可以为终端设备配置与业务的传输周期相适应的PDCCH搜索空间集。终端设备在PDCCH搜索空间集中的PDCCH监听时机上监听PDCCH,而在其他时间终端设备可以进入节能状态(如终端设备可以关掉部分射频或基带设备,从而进入短暂的休眠状态)。然而,在典型的刷新率的情况下,业务数据的传输周期和标准支持的PDCCH搜索空间集的周期并不匹配。如NR支持的PDCCH搜索空间集的周期的取值为1、2、4、5、8、10、16、20、40、80、160、320、640、1280、2560,单位为时隙。如果采用15KHz的子载波间隔,则单个时隙的长度为1ms,PDCCH搜索空间集的周期对应为1、2、4、5、8、10、16、20、40、80、160、320、640、1280、2560ms。在典型的刷新率的情况下,如60Hz、90Hz、120Hz、180Hz,对应的业务数据的传输周期分别为16.7ms、11.1ms、8.3ms、5.6ms。
因此,如何解决PDCCH搜索空间集的周期与业务数据的传输周期的匹配问题,从而使得终端设备在没有业务数据传输时进入节能状态是一个需要解决的问题。
为此,提出了本申请实施例的以下技术方案。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
需要说明的是,虽然上述相关技术是以VR业务和AR业务进行说明的,但本申请实施例的技术方案并不局限于VR业务和AR业务,其他业务类型也适用于本申请实施例的技术方案,本申请对业务类型不做限定。

以下结合具体应用实例对本申请实施例的技术方案进行举例说明。
应用实例一
终端设备确定第一PDCCH搜索空间集,所述第一PDCCH搜索空间集用于终端设备进行PDCCH监听。其中,第一PDCCH搜索空间集具有至少两个周期,或者说第一PDCCH搜索空间集具有可变周期。终端设备在不同的时间可以使用不同的周期。
作为示例,参照图5,目标业务的传输周期为16.67ms,第一PDCCH搜索空间集具有2个周期,分别为16ms和17ms。可以使用两个16ms的周期加一个17ms的周期以匹配3个16.67ms的业务传输周期。
第一PDCCH搜索空间集的配置信息是预设的或者由网络设备配置的。在一些可选实施方式中,第一PDCCH搜索空间集的配置信息包括以下至少之一:
第一信息,所述第一信息用于确定第一PDCCH搜索空间集的至少两个周期;

如图5的例子中,所述第一信息用于指示2个周期:16ms,17ms。这里,如果周期的单位以时隙表示时,当子载波间隔为15KHz时,所述第一信息用于指示2个周期:16个时隙,17个时隙。所述第二信息用于指示16ms出现的次数为2次且第一位出现,17ms出现的次数为1次且第二位出现。
应用实例二
终端确定第一PDCCH搜索空间集图样,所述第一PDCCH搜索空间集图样用于终端设备进行PDCCH监听。其中,第一PDCCH搜索空间集图样包括至少两个不同的PDCCH搜索空间集。
第一PDCCH搜索空间集图样的配置信息是预设的或者由网络设备配置的。在一些可选实施方式中,第一PDCCH搜索空间集图样的配置信息包括以下至少之一:
第三信息,所述第三信息用于确定第一PDCCH搜索空间集图样中的至少两个PDCCH搜索空间集;
第四信息,所述第四信息用于确定一次循环中所述至少两个PDCCH搜索空间集中的每个PDCCH搜索空间集出现的位置。这里,所述第四信息用于确定一次循环中所述至少两个PDCCH搜索空间集中的每个PDCCH搜索空间集出现的次数以及出现的顺序。
作为示例,参照图5,目标业务的传输周期为16.67ms,第一PDCCH搜索空间集图样包括2个PDCCH搜索空间集,分别为PDCCH搜索空间集1和PDCCH搜索空间集2,其中,PDCCH搜索空间集1的周期为16ms,PDCCH搜索空间集2的周期为17ms。可以使用两个16ms的PDCCH搜索空间集的周期加一个17ms的PDCCH搜索空间集的周 期以匹配3个16.67ms的业务传输周期。在第一PDCCH搜索空间集图样中,周期为16ms的PDCCH搜索空间集1出现2次且第一位出现,而周期为17ms的PDCCH搜索空间集2出现1次且第二位出现。进一步地,第一PDCCH搜索空间集图样在时域上重复出现。
作为示例,参照图6,目标业务的传输周期为20ms,第一PDCCH搜索空间集图样包括2个PDCCH搜索空间集,分别为PDCCH搜索空间集1和PDCCH搜索空间集2,其中,PDCCH搜索空间集1和PDCCH搜索空间集2的周期都是20ms,PDCCH搜索空间集1和PDCCH搜索空间集2的“duration”(即上述方案中的第三参数)不同,PDCCH搜索空间集1的duration为4个时隙,PDCCH搜索空间集2的duration为8个时隙,在第一PDCCH搜索空间集图样中,duration为4个时隙的PDCCH搜索空间集1出现2次且第一位出现,而duration为8个时隙的PDCCH搜索空间集2出现1次且第二位出现。这种PDCCH搜索空间集图样可以匹配在不同的业务周期业务量不同的情况,从而在业务量较多的周期使用较长的duration,在业务量较小的周期使用较小的duration。
本申请实施例的技术方案,终端设备基于具有至少两个周期的第一PDCCH搜索空间集进行PDCCH监听,或者终端设备基于由至少两个PDCCH搜索空间集构成的第一PDCCH搜索空间集图样进行PDCCH监听。由于第一PDCCH搜索空间集或者第一PDCCH搜索空间集图样在周期上更具灵活性,因而可以最大程度地适配于业务数据的传输周期,从而使得在传输业务数据的同时,使得终端设备有节能机会。
