Description
本申请实施例涉及移动通信技术领域,具体涉及一种识别媒体接入控制(Media Access Control,MAC)控制单元(Control Element,CE)类型的方法及装置、终端设备、网络设备。
在服务小区(Serving Cell,SCell)激活过程中,SCell的激活时延主要受同步信号块(Synchronization Signal Block,SSB)周期的影响。若终端设备在接收到SCell激活指令后,刚好错过了一个SSB周期,那么SCell的激活时延就会延长。为了优化这个问题,可以引入临时参考信号(Temporay Reference Signal,TRS)来替代SSB,从而实现更加快速的SCell激活。
为了实现TRS的激活,有需求引入一个新的MAC CE,通过这个新的MAC CE指示TRS是否被激活。终端设备如何区分这个新的MAC CE和传统的MAC CE(Legacy MAC CE)需要解决。

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。
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(3
rd 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(enhanced Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications,URLLC)、大规模机器类通信(massive Machine-Type Communications,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之间紧密合作(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。
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。为了满足高速率的需求,5G中支持载波聚合(Carrier Aggregation,CA)技术。CA即通过联合调度和使用多个成员载波(Component Carrier,CC)上的资源,使得NR***可以支持更大的带宽,从而能够实现更高的***峰值速率。根据所聚合载波的在频谱上的连续性可以分为,连续性载波聚合和非连续性载波聚合;根据聚合的载波所在的频段(band)是否相同,分为频段内(Intra-band)载波聚合和频段间(inter-band)载波聚合。
在CA中,有且只有一个主载波(Primary Cell Component,PCC),PCC提供RRC信令连接,非接入层(Non-Access Stratrum,NAS)功能,安全等。物理上行控制信道(Physical Downlink Control Channel,PUCCH)在PCC上且只在PCC上存在。在CA中,可以有一个或多个辅载波(Secondary Cell Component,SCC),SCC只提供额外的无线资源。PCC和SCC统称为服务小区(Serving Cell,SCell),其中,PCC上的小区为主小区(Primary Cell),SCC上的小区为辅小区(Secondary Cell)。
图2和图3是载波聚合场景下的协议栈架构图,其中,图2是针对下行的协议栈架构图,图3是针对上行的协议栈架构图,可以看出,在载波聚合中,所有载波共用一个媒体接入控制(Media Access Control,MAC)实体,每个载波对应一个HARQ实体。每个HARQ实体维护各自的多个HARQ进程(HARQ process)。
网络设备可以通过MAC CE指示终端设备激活一个或多个SCell,和/或去激活一个或多个SCell,该MAC CE可以称为SCell激活/去激活MAC CE。SCell激活/去激活MAC CE具有固定的长度。作为一种实现方式,SCell激活/去激活MAC CE的长度为1个字节,适用于网络设备为终端设备配置了小于等于7个SCell的场景。作为另一种实现方式,SCell激活/去激活MAC CE的长度为固定的4个字节,适用于网络设备为终端设备配置了大于7且小于等于31个SCell的场景。这两种长度的MAC CE分别关联不同的逻辑信道标识(Logical Channel Identify,LCID),终端设备可以根据LCID对这两种长度的MAC CE进行区分。如图4所示,SCell激活/去激活MAC CE的长度为1个字节,控制7个SCell的状态;如图5所示,SCell激活/去激活MAC CE的长度为4个字节,控制31个SCell的状态。其中,C
i代表服务小区索引(Serving Cell index)为i的SCell对应的激活/去激活指示信息;若C
i的取值为1,则用于指示激活服务小区索引为i的SCell,若C
i的取值为0,则用于指示去激活服务小区索引为i的SCell。进一步,若网络设备没有为终端设备配置服务小区索引为i的SCell,则终端设备忽略C
i的取值。此外,R代表预留比特位,R的取值默认为0。
在SCell激活过程中,假设终端设备在时隙n上接收到用于指示激活SCell的MAC CE,那么,终端设备发送信道状态信息报告(Channel State Information report,CSI report)及执行SCell激活行为的时间不晚于:
其中,slot length代表时隙长度,slot length与子载波间隔有关。T
HARQ代表HARQ对应的时间、T
activation_time代表激活SCell对应的时间、T
CSI_Reporting代表CSI上报对应的时间。其中,SCell激活时延主要受T
activation_time这一参数的影响,而T
activation_time取决于SSB周期,作为示例,SSB周期可以为5ms,10ms,20ms,40ms,80ms,160ms。若终端设备在接收到用于指示激活SCell的MAC CE后,刚好错过了一个SSB周期,那么SCell的激活时延就会延长。为了优化这个问题,可以引入TRS来替代SSB,终端设备在接收到SCell激活指令以及TRS激活指令后,可以根据配置执行TRS的测量,从而实现快速的SCell激活。
为了实现SCell激活以及TRS激活,有需求引入一个新的MAC CE,新的MAC CE可以同时用于指示多个SCell中的每个SCell是否被激活或者去激活,以及用于指示所述多个SCell中的至少部分SCell的TRS是否被激活。为了让终端设备识别这个新的MAC CE,需要为这个新的MAC CE分配一个LCID。然而,由于LCID资源有限,这个新的MAC CE关联的LCID复用传统的SCell激活/去激活MAC CE关联的LCID,以节省LCID资源。然而,如果这个新的MAC CE关联的LCID与传统的SCell激活/去激活MAC CE关联的LCID相同,终端设备无法区分这个新的MAC CE关联与传统的SCell激活/去激活MAC CE。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。
图6是本申请实施例提供的识别MAC CE类型的方法的流程示意图,如图6所示,所述识别MAC CE类型的方法包括以下步骤:
步骤601:终端设备接收网络设备发送的MAC CE和所述MAC CE对应的MAC子头,所述MAC子头携带所述MAC CE关联的LCID。
本申请实施例中,网络设备向终端设备发送MAC CE和所述MAC CE对应的MAC子头,相应地,终端设备接收网络设备发送的MAC CE和所述MAC CE对应的MAC子头。在一些可选实施方式中,所述网络设备为基站。
步骤602:所述终端设备确定所述MAC CE的类型为第一类MAC CE或第二类MAC CE,其中,所述第一类MAC CE关联的LCID和所述第二类MAC CE关联的LCID相同。
本申请实施例中,所述第一类MAC CE用于指示多个SCell中的每个SCell是否被激活或者去激活。所述第一类MAC CE也即是传统的SCell激活/去激活MAC CE。
本申请实施例中,所述第二类MAC CE用于指示多个SCell中的每个SCell是否被激活或者去激活,以及用于指示所述多个SCell中的至少部分SCell的TRS是否被激活。所述第二类MAC CE也即是新的MAC CE。
在一些可选实施方式中,所述至少部分SCell包括所述多个SCell中的被激活的SCell;或者,所述至少部分SCell包括所述多个SCell中的全部SCell。
作为示例:所述第二类MAC CE用于指示多个SCell中的每个SCell是否被激活或者去激活,以及用于指示所述多个SCell中的被激活的SCell的TRS是否被激活。
作为示例:所述第二类MAC CE用于指示多个SCell中的每个SCell是否被激活或者去激活,以及用于指示所述多个SCell中的每个SCell的TRS是否被激活。
需要说明的是,本申请实施例的技术方案对所述第二MAC CE的名称不做限定。
需要说明的是,本申请实施例的技术方案对所述第二类MAC CE指示的多个SCell的数目不做限定。作为一种实现方式,所述第二类MAC CE指示的多个SCell的数目可以是7个,适用于网络设备为终端设备配置了小于等于7个SCell的场景。作为另一种实现方式,所述第二类MAC CE指示的多个SCell的数目可以是31个,适用于网络设备为终端设备配置了大于7且小于等于31个SCell的场景。
本申请实施例中,所述网络设备向所述终端设备指示MAC CE的类型为第一类MAC CE或第二类MAC CE;终端设备接收到MAC CE后,基于网络设备的指示确定MAC CE的类型为第一类MAC CE或第二类MAC CE。
以下对终端设备如何确定接收到的MAC CE的类型是第一类MAC CE还是第二类MAC CE进行说明。
方案一
本申请实施例中,所述网络设备通过第一指示信息向所述终端设备指示所述MAC CE的类型为第一类MAC CE或第二类MAC CE。相应地,所述终端设备基于第一指示信息,确定所述MAC CE的类型为第一类MAC CE或第二类MAC CE。
在一些可选实施方式中,所述第一指示信息携带在所述MAC子头中,所述第一指示信息用于指示所述MAC CE的类型为第一类MAC CE或第二类MAC CE。
在一些可选实施方式中,所述第一指示信息为N比特的指示信息,N为正整数;
所述N比特的取值为第一值,用于指示所述MAC CE的类型为第一类MAC CE;
或者,
所述N比特的取值为第二值,用于指示所述MAC CE的类型为第二类MAC CE。
作为示例:所述第一指示信息为1比特的指示信息。1比特的取值为0,用于指示MAC CE的类型为第一类MAC CE;1比特的取值为1,用于指示MAC CE的类型为第二类MAC CE。或者反之,1比特的取值为1,用于指示MAC CE的类型为第一类MAC CE;1比特的取值为0,用于指示MAC CE的类型为第二类MAC CE。这里,可以将1比特的指示信息所在的字段称为T字段,需要说明的是,本申请对1比特的指示信息所在的字段的名称不做限定。
方案二
本申请实施例中,所述网络设备通过第一指示信息向所述终端设备指示所述MAC CE的类型为第一类MAC CE或第二类MAC CE。相应地,所述终端设备基于第一指示信息,确定所述MAC CE的类型为第一类MAC CE或第二类MAC CE。
在一些可选实施方式中,所述第一指示信息携带在所述网络设备发送的无线资源控制(Radio Resource Control,RRC)消息中,所述第一指示信息用于指示所述MAC CE的类型为第一类MAC CE或第二类MAC CE。
方案三
本申请实施例中,所述网络设备通过是否在RRC消息中携带第一指示信息,向所述终端设备指示所述MAC CE的类型为第一类MAC CE或第二类MAC CE。相应地,所述终端设备基于所述网络设备发送的RRC消息中是否存在第一指示信息,确定所述MAC CE的类型为第一类MAC CE或第二类MAC CE,所述第一指示信息用于指示MAC CE的类型。
具体地,若所述网络设备发送的RRC消息中存在第一指示信息,则所述终端设备确定所述MAC CE的类型为第二类MAC CE(即:若所述RRC消息中携带第一指示信息,则指示所述MAC CE的类型为第二类MAC CE);或者,若所述网络设备发送的RRC消息中不存在第一指示信息,则所述终端设备确定所述MAC CE的类型为 第一类MAC CE(即:若所述RRC消息中未携带第一指示信息,则指示所述MAC CE的类型为第一类MAC CE)。可选地,所述第一指示信息用于指示所述MAC CE的类型为第二类MAC CE。
方案四
本申请实施例中,所述网络设备通过是否为SCell配置TRS,向所述终端设备指示所述MAC CE的类型为第一类MAC CE或第二类MAC CE。相应地,所述终端设备基于多个SCell中是否存在SCell配置了TRS,确定所述MAC CE的类型为第一类MAC CE或第二类MAC CE。
具体地,若多个SCell中存在至少一个SCell配置了TRS,则所述终端设备确定所述MAC CE的类型为第二类MAC CE(即:若多个SCell中存在至少一个SCell配置了TRS,则指示所述MAC CE的类型为第二类MAC CE);或者,若多个SCell中不存在SCell配置了TRS,则所述终端设备确定所述MAC CE的类型为第一类MAC CE(即:若多个SCell中不存在SCell配置了TRS,则指示所述MAC CE的类型为第一类MAC CE)。
对于上述任意一种方案来说,所述第二类MAC CE的长度为固定长度;或者,所述第二类MAC CE的长度为可变长度。
这里,若所述第二类MAC CE用于指示多个SCell中的每个SCell是否被激活或者去激活,以及用于指示所述多个SCell中的被激活的SCell的TRS是否被激活,那么,所述第二类MAC CE的长度为可变长度。这是由于被激活的SCell的数目是可变的,因而所述第二类MAC CE中用于指示被激活的SCell的TRS是否被激活的信息长度是可变的。
这里,若所述第二类MAC CE用于指示多个SCell中的每个SCell是否被激活或者去激活,以及用于指示所述多个SCell中的每个SCell的TRS是否被激活,那么,述第二类MAC CE的长度为固定长度。这是由于多个SCell的数目是不变的。
进一步,在一些可选实施方式中,所述第二类MAC CE的长度为可变长度的情况下,所述MAC子头还携带第二指示信息,所述第二指示信息用于指示所述第二类MAC CE的长度。这里,可以将第二指示信息所在的字段称为L字段,需要说明的是,本申请对第二指示信息所在的字段的名称不做限定。
进一步,在一些可选实施方式中,所述MAC子头还携带第三指示信息,所述第三指示信息用于指示所述第二指示信息占据的比特长度。这里,可以将第三指示信息所在的字段称为F字段,需要说明的是,本申请对第三指示信息所在的字段的名称不做限定。
在一些可选实施方式中,所述第三指示信息为M比特的指示信息,M为正整数;其中,所述M比特的取值为第一值,用于指示所述第二指示信息占据的比特长度为第一比特长度;或者,所述M比特的取值为第二值,用于指示所述第二指示信息占据的比特长度为第二比特长度。
作为示例:所述第三指示信息为1比特的指示信息。1比特的取值为0,用于指示所述第二指示信息占据的比特长度为第一比特长度(如8比特长度);1比特的取值为1,用于指示所述第二指示信息占据的比特长度为第二比特长度(如16比特长度)。或者反之,1比特的取值为1,用于指示所述第二指示信息占据的比特长度为第一比特长度(如8比特长度);1比特的取值为0,用于指示所述第二指示信息占据的比特长度为第二比特长度(如16比特长度)。
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。
