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相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communication,URLLC)、大规模机器类通信(massive Machine Type Communication,mMTC)。
一方面,eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,例如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
在NR早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下,可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资,提出了LTE和NR之间紧密配合(tight interworking)的工作模式。
为了能够尽快实现5G网络部署和商业应用,3GPP首先完成第一个5G版本,即EN-DC(LTE-NR Dual Connectivity)。在EN-DC中,LTE基站(eNB)作为主节点(Master Node,MN),NR基站(gNB或en-gNB)作为辅节点(Secondary Node,SN),连接EPC核心网。在R15后期,将支持其他DC模式,即NE-DC,5GC-EN-DC,NR DC。在NE-DC中,NR基站作为MN,eLTE基站作为SN,连接5GC核心网。在5GC-EN-DC中,eLTE基站作为MN,NR基站作为SN,连接5GC核心网。在NR DC中,NR基站作为MN,NR基站作为SN,连接5GC核心网。
NR也可以独立部署。NR将来会部署在高频上,为了提高覆盖,在5G中,通过引入波束扫描(beam sweeping)的机制来满足覆盖的需求(用空间换覆盖,用时间换空间)。在引入beam sweeping后,每个波束方向上都需要发送同步信号,5G的同步信号以同步信号块(SS/PBCH block,SSB)的形式给出,包含主同步信号(Primary Synchronisation Signal,PSS)、辅同步信号(Secondary Synchronisation Signal,SSS)、和物理广播信道(Physical Broadcast Channel,PBCH)。5G的同步信号以同步信号突发组(SS burst set)的形式在时域上周期性出现。
在5G中,最大的信道带宽可以是400MHZ(称为宽带载波(wideband carrier)),相比于LTE最大20M带宽来说,宽带载波的带宽很大。如果终端设备保持工作在宽带载波上,则终端设备的功率消耗非常大。所以建议终端设备的射频(Radio Frequency,RF)带宽可以根据终端设备实际的吞吐量来调整。为此,引入带宽部分(Band Width Part,BWP)的概念,BWP的动机是优化终端设备的功率消耗。例如终端设备的速率很低,可以给终端设备配置小一点的BWP,如果终端设备的速率要求很高,则可以给终端设备配置大一点的BWP。如果终端设备支持高速率,或者工作在载波聚合(Carrier Aggregation,CA)模式下,可以给终端设备配置多个BWP。BWP的另一个目的就是触发一个小区中多个基础参数集(numerology)共存,例如BWP1对应numerology1,BWP2对应numerology2。
空闲状态或者非激活状态的终端设备驻留在初始BWP(initial BWP)上,初始BWP对于空闲状态或者非激活状态的终端设备是可见的,终端设备从初始BWP上可以获取主信息块(Master Information Block,MIB),剩余最小系统信息(Remaining Minimum System Information,RMSI),其他系统信息(Other System Information,OSI)以及寻呼(paging)等信息。
对于RRC连接状态的终端设备,通过RRC专用信令可以给一个终端配置最多4个上行BWP和最多4个下行BWP,但同一时刻只能有一个上行BWP和下行BWP被激活。在RRC专用信令中,可以指示所配置的BWP中第一个激活的BWP。同时在终端设备处于RRC连接状态的过程中,也可以通过下行控制信息(Downlink Control Information,DCI)在不同的BWP之间切换。当处于非激活状态的载波,进入激活状态后,第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。每个BWP的配置参数包括:
-子载波间隔(Subcarrier Spacing,SCS);
-循环前缀(Cyclic Prefix);
-BWP的第一个物理资源块(Physical Resource Block,PRB)以及连续的PRB个数(locationAndBandwidth);
-BWP标识(bwp-Id);
-BWP公共配置参数(bwp-Common)和BWP专用配置参数(bwp-Dedicated)。
终端设备在进行无线链路监控(Radio Link Monitor,RLM)过程中,只在激活的BWP上执行,非激活的BWP不需要操作,而在不同BWP之间进行切换的时候,也不需要重置RLM相关的定时器和计数器。对于无线资源管理(Radio Resource Management,RRM)测量,无论终端设备在哪个激活的BWP上收发数据,都不影响RRM测量。对于信道质量指示(Channel Quality Indication,CQI)的测量,终端设备也只需要在激活的BWP上执行。
当一个载波被去激活,然后通过媒体接入控制控制单元(Media Access Control Control Element,MAC CE)激活了该载波,则初始的第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。
BWP标识(BWP id)在RRC专用信令中的取值为0到4,BWP标识为0的BWP默认为初始BWP。
在DCI中BWP指示(BWP indicator)为2比特(bit),如下表1所示。如果配置的BWP个数小于等于3个,则BWP indicator=1,2,3分别对应BWP id=1,2,3。如果BWP的个数为4个,则BWP indicator=0,1,2,3分别对应按照顺序索引配置的BWP。而且网络侧在配置BWP的时候使用连续的BWP id。

表1
为了支持终端设备的节能以及快速建立SCG,标准上同意引入SCG去激活的概念,然而,SCG去激活后,PSCell的状态尚未明确,如何支持CSI测量上报需要解决。
为此,提出了本申请实施例的以下技术方案。
图2是本申请实施例提供的SCG的管理方法的流程示意图,如图2所示,所述SCG的管理方法包括以下步骤:
步骤201:终端设备在SCG去激活后,确定PSCell的状态。
本申请实施例中,MCG为MN侧的小区组(Cell Group,CG),SCG为SN侧的小区组。其中,MCG包括一个PCell以及一个或多个SCell,SCG包括一个PScell以及一个或多个SCell。无论是PCell、PScell还是SCell,都属于服务小区(Serving Cell),服务小区具有对应的服务小区标识。
在一些可选实施方式中,SCG去激活后,SCG中的全部SCell处于去激活状态。
在一些可选实施方式中,SCG去激活后,SCG中的部分SCell处于去激活状态。
本申请实施例中,SCG去激活后,SCG中的PSCell可以处于去激活状态或者具有休眠行为的激活状态。这里,需要说明的是,一个服务小区的状态可以有如下几种:去激活状态、具有休眠行为的激活状态、具有非休眠行为的激活状态。其中,具有非休眠行为的激活状态也可以简称为激活状态。
对于具有休眠行为的激活状态来说,可以通过休眠(dormant)BWP来实现,具体地,将服务小区的休眠BWP激活,从而该服务小区进入具有休眠行为的激活状态。这里,休眠BWP是通过RRC专用信令配置的一个专用BWP,终端设备在服务小区的休眠BWP上不执行物理下行控制信道(Physical Downlink Control Channel,PDCCH)的监听,不执行物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的接收,不执行物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的发送,但是,终端设备在休眠BWP上执行CSI测量、CSI测量上报以及波束管理等。
对于PSCell来说,PSCell上配置有休眠BWP,PSCell激活休眠BWP后的状态为具有休眠行为的激活状态。这里,PSCell激活休眠BWP,也可以理解为,PSCell的激活BWP切换到了休眠BWP。
本申请实施例中,如何实现SCG去激活,以及如何确定SCG去激活后PSCell的状态,可以通过以下方式实现。
方式一
所述终端设备接收SCG去激活命令,所述SCG去激活命令用于触发SCG去激活, 所述SCG去激活命令还用于触发所述PSCell激活休眠BWP,其中,所述PSCell激活休眠BWP后的状态为具有休眠行为的激活状态。
这里,可选地,当且仅当终端设备接收到SCG去激活命令后,才激活PSCell的休眠BWP(或者说触发PSCell进入休眠BWP)。其他命令不能让终端设备激活PSCell的休眠BWP,例如承载在DCI中的BWP切换命令。
方式二
所述终端设备接收第一配置信息,所述第一配置信息用于配置第一定时器,所述第一定时器用于触发SCG去激活,所述第一定时器还用于触发所述PSCell激活休眠BWP,其中,所述PSCell激活休眠BWP后的状态为具有休眠行为的激活状态。
在一些可选实施方式中,所述第一配置信息携带在RRC专用信令中。具体地,所述第一配置信息包括所述第一配置信息的时长信息。
在一些可选实施方式中,所述第一配置信息由MCG配置,也可以理解为,所述第一配置信息由PCell配置。
在一些可选实施方式中,所述第一配置信息由SCG配置,也可以理解为,所述第一配置信息由PSCell配置。
本申请实施例中,所述终端设备接收到所述第一配置信息后,基于所述第一配置信息启动所述第一定时器;若所述终端设备确定所述SCG侧有数据调度或者数据传输,则所述终端设备重启所述第一定时器;若所述第一定时器超时,则所述终端设备确定SCG自动去激活,且所述PSCell激活休眠BWP。
上述方案中,所述第一定时器还用于触发所述PSCell激活休眠BWP,可替换地,所述第一定时器还用于触发所述PSCell进入去激活状态。具体地,终端设备接收到所述第一配置信息后,基于所述第一配置信息启动所述第一定时器;若所述终端设备确定所述SCG侧有数据调度或者数据传输,则所述终端设备重启所述第一定时器;若所述第一定时器超时,则所述终端设备确定SCG自动去激活,且所述PSCell进入去激活状态。
上述方案中,所述终端设备可以通过以下方式确定所述SCG侧有数据调度或者数据传输:
1)若所述终端设备接收到了用于调度所述SCG侧数据传输的DCI,则确定所述SCG侧有数据调度;或者,
2)若所述终端设备接收到了所述SCG侧的MAC PDU,则确定所述SCG侧有数据传输;或者,
3)若所述终端设备发送了所述SCG侧的MAC PDU,则确定所述SCG侧有数据传输。
步骤202:所述终端设备在所述PSCell处于具有休眠行为的激活状态的情况下,执行针对所述PSCell的CSI测量并上报CSI测量报告。
本申请实施例中,SCG去激活后,由于PSCell可以处于具有休眠行为的激活状态,换句话说,PSCell可以处于激活状态且激活BWP是休眠BWP,因此支持PSCell的CSI测量上报。
本申请实施例中,终端设备按照SCG配置的针对PSCell的信道状态指示-参考信号(Channel Status Indicator-Reference Signal,CSI-RS),执行CSI测量。
本申请实施例中,为了实现CSI测量报告(CSI report)的上报,需要网络侧为终端设备配置物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源,这里,PUCCH资源例如是PUCCH-CSI-Resource。
这里,PUCCH资源可以是PCell上的PUCCH资源或者是PSCell上的PUCCH资源。 对于PUCCH资源是PCell上的PUCCH资源的情况,属于跨CG上报方式;对于PUCCH资源是PSCell上的PUCCH资源的情况,不属于跨CG上报方式。以下对其进行描述。
上报方式一
在一些可选实施方式中,所述终端设备通过PCell上的PUCCH资源,上报所述PSCell的CSI测量报告。
这里,所述终端设备接收第二配置信息,所述第二配置信息用于配置所述PCell上的PUCCH资源,所述PUCCH资源用于传输所述PSCell的CSI测量报告。进一步,可选地,所述第二配置信息还用于配置以下至少之一:
CSI测量报告的上报周期;
CSI测量报告的上报时隙位置
用于传输CSI测量报告的PUCCH资源的周期;
用于传输CSI测量报告的PUCCH资源的时隙位置。
上述方案中,可选地,所述第二配置信息携带在RRC专用信令中。
上报方式二
在一些可选实施方式中,所述终端设备通过PSCell上的PUCCH资源,上报所述PSCell的CSI测量报告。
这里,所述PSCell上的PUCCH资源为休眠BWP上的PUCCH资源;或者,所述PSCell上的PUCCH资源为非休眠BWP上的PUCCH资源。
需要说明的是,当SCG去激活后,仅仅PSCell上的CSI-RS关联的CSI测量上报被继续触发,其他的测量上报被去激活。
本申请实施例中,SCG去激活后,PSCell侧的PDCCH、PDSCH的TCI状态(TCI state)需要明确,从而可以实现对PDCCH、PDSCH的波束管理。这里,需要说明的是,PDCCH的TCI状态用于确定PDCCH关联的波束,PDSCH的TCI状态用于确定PDSCH关联的波束,如何确定PDCCH的TCI状态和PDSCH的TCI状态需要明确,以下对其进行说明。
所述终端设备接收MCG发送的第一MAC CE和/或第二MAC CE,所述第一MAC CE用于确定PSCell侧的PDCCH的被激活的TCI状态,所述第二MAC CE用于确定PSCell侧的PDSCH的被激活的TCI状态。
在一些可选实施方式中,所述第一MAC CE携带所述PSCell的服务小区标识,所述第二MAC CE携带所述PSCell的服务小区标识。
作为示例,第一MAC CE为UE专用PDCCH MAC CE(UE-specific PDCCH MAC CE),UE专用PDCCH MAC CE携带一个TCI状态标识和一个服务小区标识,其中,所述TCI状态标识用于指示被激活的一个TCI状态,所述服务小区标识为PSCell的服务小区标识。终端设备根据第一MAC CE,可以确定出PSCell的PDCCH的被激活的一个TCI状态。
作为示例,第二MAC CE为UE专用PDSCH MAC CE(UE-specific PDSCH MAC CE),UE专用PDSCH MAC CE中的部分字节用于指示多个TCI状态中的每个TCI状态是处于激活状态还是处于去激活状态,具体地,字节中的每个比特位对应一个TCI状态标识,比特位的取值(例如1或者0)用于指示该比特位对应的TCI状态标识所指示的TCI状态是处于激活状态还是处于去激活状态,此外,UE专用PDSCH MAC CE还携带一个服务小区标识,所述服务小区标识为PSCell的服务小区标识。终端设备根据第二MAC CE,可以确定出PSCell的PDSCH的被激活的一个或多个TCI状态。
需要说明的是,第一MAC CE和/或第二MAC CE通过MCG的MAC层发送。
基于所述第二MAC CE确定的被激活的TCI状态的数目为多个的情况下,需要进 一步确定PDSCH的TCI状态是多个TCI状态中的哪一个。以下对其进行描述。
方式A)所述终端设备接收MCG发送的第一DCI,所述第一DCI携带第一TCI状态标识,所述第一TCI状态标识用于指示多个被激活的TCI状态中的第一TCI状态;其中,所述第一TCI状态用于所述PSCell侧的PDSCH传输。进一步,可选地,所述第一DCI还携带所述SCG的指示信息和/或所述PSCell的服务小区标识。
作为示例,通过第二MAC CE确定出处于激活状态(或者说被激活)的TCI状态有8个,分别为TCI状态1~TCI状态8。终端设备接收MCG发送的DCI,该DCI携带一个TCI状态标识,其中,所述TCI状态标识用于指示8个TCI状态中的TCI状态3。终端设备根据该DCI,可以确定出PSCell的PDSCH基于TCI状态3进行传输。
方式B)所述终端设备接收MCG发送的第三MAC CE,所述第三MAC CE携带第一TCI状态标识,所述第一TCI状态标识用于指示多个被激活的TCI状态中的第一TCI状态;其中,所述第一TCI状态用于所述PSCell侧的PDSCH传输。
这里,第三MAC CE与上述第一MAC CE和第二MAC CE不同,是新定义的一个MAC CE,为了区分该新定义的MAC CE,可以为该新定义的MAC CE定义新的逻辑信道标识(LCID),终端设备根据LCID可以确定出第三MAC CE中携带的内容是什么。
作为示例,通过第二MAC CE确定出处于激活状态(或者说被激活)的TCI状态有8个,分别为TCI状态1~TCI状态8。终端设备接收MCG发送的第三MAC CE,该第三MAC CE携带一个TCI状态标识,其中,所述TCI状态标识用于指示8个TCI状态中的TCI状态3。终端设备根据该第三MAC CE,可以确定出PSCell的PDSCH基于TCI状态3进行传输。
本申请实施例中,SCG去激活后,RRM测量可以进行放松。
具体地,所述终端设备在SCG去激活后,执行针对所述SCG中的至少一个服务小区关联的测量;服务小区关联的测量是指该服务小区配置的测量对象的测量。所述终端设备基于所述测量对象关联的测量配置上报测量报告,所述测量配置通过测量标识(measurement id)进行标识。
