Description

通信方法、装置和系统
本申请要求于2020年02月17日提交中国专利局、申请号为202010097211.7、申请名称为“通信方法、装置和系统”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
本申请实施例涉及通信技术领域,尤其涉及一种通信方法、装置和系统。
背景技术
在5G通信系统中,参考信号(reference signal,RS)可以被用作多种用途。例如用于用户设备(user equipment,UE)进行自动增益控制(Automatic Gain Control,AGC)调整、时频同步、波束测量及无线资源管理(Radio Resource Management,RRM)测量等。为了降低网络的资源开销,从设计之初就避免引入过多的小区级别参考信号,最终确定的小区级别的参考信号在同步信号块(synchronization signal block,SSB)中发送。其中,SSB会周期性发送,并且在某些时隙(NR中时隙为基本调度单位,其长度与子载波间隔大小有关)中发送。例如,在子载波间隔为15kHz的时候,一个时隙长度为1ms,此时一种可能的配置如图1所示,4个SSB在2ms的时间内发送完毕,但是下个周期的4个SSB要在20ms之后才会发送。
若UE处于去激活态(INACTIVE态)或空闲态(IDLE)态时,会在寻呼时机(paging occasion,PO)接收网络侧发送的寻呼(paging),UE在接收paging之前需要接收paging下行控制信息(downlink control information,DCI)。而且UE在接收paging DCI之前,为了保证paging DCI的接收性能足够好,需要提前进行AGC调整、时频同步等工作,如前面所说,这些工作需要借助参考信号。
目前,参考信号的配置信息可以通过广播消息发送给UE,每个参考信号的配置信息所占的比特位较多,一个广播消息包括的参考信号的配置信息的数量有限,无法满足发送更多参考信号的配置信息的需求。

具体实施方式
图3为本申请实施例提供的通信系统的示意图,如图3所示,通信系统包括网络设备和终端设备。
以下,对本申请中的部分用语进行解释说明,以便于本领域技术人员理解:
网络设备:又称为无线接入网(Radio Access Network,RAN)设备,是一种将终端设备接入到无线网络的设备,可以是长期演进(Long Term Evolution,LTE)中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者5G网络中的基站,如发送和接收点(Transmission and Reception Point,TRP)、控制器,在此并不限定。一种可能的方式中,接入网设备可以是CU和DU分离架构的基站(如gNB),如图4所示,图4为本申请一实施例提供的网络设备的协议栈示意图。RAN设备可以与核心网设备相连(例如可以是LTE的核心网,也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连,例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如无线资源控制(Radio Resource Control,RRC)、业务数据适配协议栈(Service Data Adaptation Protocol,SDAP)以及分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能设置在CU,而无线链路控制(radio link control,RLC),媒体接入控制(Media Access Control,MAC)层,物理(physical,PHY)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例,也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如,CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中,将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中,还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分, 将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。在另一种设计中,CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置,也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能,也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如,可以对CU的功能进行进一步切分,例如,将控制面(CP)和用户面(UP)分离,即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如,CU-CP和CU-UP可以由不同的功能实体来实现,所述CU-CP和CU-UP可以与DU相耦合,共同完成基站的功能。一种可能的方式中,CU-CP负责控制面功能,主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密,完整性保护,数据传输等。CU-UP负责用户面功能,主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密,完整性保护,头压缩,序列号维护,数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
终端设备:可以是无线终端设备也可以是有线终端设备,无线终端设备可以是指一种具有无线收发功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality,VR)终端、增强现实(Augmented Reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等,在此不作限定。可以理解的是,本申请实施例中,终端设备也可以称为用户设备(user equipment,UE)。
在5G移动通信系统中,终端设备所处的状态包括:连接态、空闲态以及去激活态(inactive)。终端设备处于连接态时,与网络设备建立空口连接,并根据空口连接与网络设备通信。终端设备处于空闲态时,终端设备与网络设备的空口连接断开,不再保存上下文信息,终端设备只能接收网络设备发送的广播信息,终端设备处于去激活态时,终端设备与网络设备的空口连接断开,但是继续保存上下文信息,当终端设备由去激活态进入连接态时,基于保存的上下文信息,能快速地恢复到连接态。
在终端设备在处于去激活态或空闲态时,会周期性的接收网络设备发送的寻呼消息(paging)。具体过程为:当处于去激活态或空闲态的终端设备有下行业务产生的时候,网络设备应当告知该终端设备有下行业务,并让该终端设备转入连接态。目前,网络设备通过发送寻呼消息,来告知终端设备有下行业务的。为了避免终端设备的功耗过大,网络设备会周期性发送寻呼消息,每个周期(paging DRX cycle)会出现一个寻呼时机(paging occasion,PO),在PO内网络设备可以下发寻呼消息,终端设备检测是否有寻呼消息。
终端设备在监测寻呼消息的时候,首先要监测paging下行控制信息(downlink control information,DCI)。Paging DCI使用paging无线网络临时标识(radio network temporary  identifier,RNTI)进行标识,只有被分配了对应的paging RNTI的UE能够检测到paging DCI。终端设备(一般是多个终端设备)在收到paging DCI后,会根据该pagingDCI的指示接收携带寻呼消息的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。如果终端设备在寻呼消息中检测到了自己的标识(Identity,ID),则会发起随机接入流程以转入连接态。简而言之,paging DCI可以通知一组寻呼消息“可能需要转到连接态”,进一步寻呼消息会告诉这一组终端设备,具体是哪些终端设备真的要转到连接态。
终端设备在PO内接收paging DCI之前,为了保证paging DCI的接收性能足够好,需要提前进行AGC调整、时频同步等工作。这些工作需要借助网络设备发送的参考信号。目前,参考信号的配置信息可以通过系统信息块(system information block,SIB)消息发送给UE,一个SIB消息最多能够发送2976比特。而每个参考信号的配置信息大约需要80比特。即一个SIB消息中,最多能够广播37个参考信号的配置信息。
当网络侧使用广播消息广播附加(additional)参考信号的配置信息时,如果希望能够为小区内的UE提供尽可能可用的RS资源,考虑到小区内的UE接收paging的位置是在时间上均匀分布的网络可能需要广播多套TRS/CSI-RS才能较好地支撑不同PO的UE。
另一方面,在毫米波频段,基站最多可能发送64个波束方向的信号,如果期望辅助各个方向的UE,则至少需要64套配置信息。
如前面所述,NR中在一个SIB消息中,最多能够广播37个配置,显然是不够用的。
因此,如何降低参考信号的配置信息的信令开销是需解决的问题。
基于此,本申请提出:网络设备对通过广播信息广播参考信号资源的配置信息时,可以有如下四种方式:
第一种方式,分两级进行配置,一级为各参考信号的配置信息中的相同部分(可以称为公共部分),另一级为各参考信号的配置信息中除公共部分之外的部分。
第二种方式,分两级进行配置,一级为参考的配置信息,另一级为各参考信号的配置信息中与参考的配置信息不同的部分。
第三种方式,分两级进行配置,一级为参考的配置信息,另一级为各参考信号的配置信息中与参考的配置信息不同的部分相对于参考的配置信息取值的增量/减量。
第四种方式,预定义一些参考信号的配置信息,广播的时候广播参考信号的配置信息的标识信息。
本申请的各实施例方法可以解决上述问题。
图5为本申请一实施例提供的通信方法的流程图,如图5所示,本实施例的方法可以包括:
S501、网络设备生成广播信息。
S502、网络设备发送广播信息。相应地,终端设备接收网络设备发送的广播信息。广播信息包括:第一信息和多个第二信息。
S503、终端设备根据第一信息指示的部分或全部配置参数,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息。
本实施例中,网络设备确定多个参考信号中每个参考信号的配置信息,以多个参考信号中第i个参考信号为例,i为大于等于1的整数,第i个参考信号的配置信息包括Q i个配置参数。网络设备确定N个配置参数,以及根据多个参考信号的配置信息确定第i个参考 信号的M i个配置参数。网络设备根据N个配置参数生成第一信息,第一信息用于指示N个配置参数,N为大于等于1的整数。网络设备根据第i个参考信号的M i个配置参数生成第i个第二信息,第i个第二信息用于指示第i个参考信号的M i个配置参数,M i为大于等于0的整数,共生成多个第二信息。该多个第二信息分别对应多个参考信号。其中,Q i大于等于N,Q i大于等于M i。需要说明的是,当i的值不同时,M i的值也可能会不相同。
网络设备根据第一信息和多个第二信息,生成广播信息,该广播信息包括第一信息和多个第二信息,然后广播发送广播信息。相应地,一个或多个终端设备接收网络设备发送的广播信息。下面以其中一个终端设备接收广播信息后如何处理为例描述,其它终端设备类似,此处不再赘述。
终端设备接收到网络设备发送的广播信息后,根据第一信息指示的部分或全部配置信息,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息,即第i个参考信号的Q i个配置参数。从而终端设备可以确定多个参考信号的配置信息。
可选的,上述参考信号可以是如下一种或多种:主同步信号(primary synchronization signal,PSS)、辅同步信号(secondary synchronization signal,SSS),信道状态信息参考信号(channel state information reference signal,CSI-RS)和跟踪参考信号(tracking reference signal,TRS)。
可选的,所述N个配置参数包括如下一项或多项:周期、时隙偏移值、占用的OFDM符号位置、频域RE偏移值、端口数、CDM类型、频域密度、扰码ID、映射的起始RB、映射的RB数量。
本实施例的通信方法,通过网络设备发送广播信息,广播信息包括:第一信息和多个第二信息,第一信息用于指示N个配置参数,第i个第二信息用于指示第i个参考信号的M i个配置参数。一个或多个终端设备接收到广播信息后,根据第一信息指示的部分或全部配置参数,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息,第i个参考信号的配置信息包括Q i个配置参数,Q i大于等于N,Q i大于等于M i。因此,终端设备并不是直接接收每个参考信号的配置信息,而是根据同一第一信息以及每个参考信号对应的第二信息,恢复出每个参考信号的配置信息,这样网络设备无需向终端设备直接发送每个参考信号的配置信息,可以节省广播信息的信令开销。另外,通过同一广播信息使终端设备获得更多数量的参考信号的配置信息。
下面采用几个具体实施例对上述方案进行详细描述。
在一些实施例中,上述N个配置参数属于多个参考信号的配置信息中相同的配置参数。该N个配置信息可以是多个参考信号的配置信息中全部相同的配置参数,也可以是多个参考信号的配置信息中部分相同的配置参数。
上述S503的一种可能的实现方式为:所述终端设备根据所述第一信息确定所述Q i个配置参数中N个配置参数,根据所述第i个第二信息确定所述Q i个配置参数中剩余M i个配置参数。本实施例中,终端设备将第一信息获得N个配置参数,并将该N个配置参数确定为第i个参考信号的Q i个配置参数中的N个配置参数,以及根第i个第二信息获得M i个配置参数,并将M i个配置参数确定为Q i个配置参数中的M i个配置参数,从而获得第i个参考信号的Q i个配置参数。也就是,第i个参考信号的Q i个 配置参数包括上述N个配置参数,也包括上述M i个配置参数。
可选的,第i个第二信息中包括M i个配置参数。可选的,第一信息包括N个配置参数。
可选的,N个配置参数的参数名称可以是预先规定的,例如:如果预先规定第一信息可以包括参数名称1、参数名称2、参数名称3的配置参数。网络设备可以确定多个参考信号的配置信息中参数名称1对应的配置参数是否相同,参数名称2对应的配置参数是否相同,参数名称3对应的配置参数是否相同,如果网络设备确定多个参考信号的配置信息中参数名称2对应的配置参数相同,则网络设备确定该相同的参数名称2对应的配置参数为N个配置参数。可选的,如果多个参考信号的配置参数中参数名称4对应的配置参数相同,则该N个配置参数不包括该参数名称4对应的配置参数。
可选的,N个配置参数的参数名称可以是多个参考信号中相同的配置参数,例如:如果每个参考信号的配置信息可以包括参数名称1、参数名称2、参数名称3、参数名称4的配置参数。网络设备可以确定多个参考信号的配置信息中参数名称1对应的配置参数是否相同,参数名称2对应的配置参数是否相同,参数名称3对应的配置参数是否相同,参数名称4对应的配置参数是否相同,如果网络设备确定多个参考信号的配置信息中参数名称2对应的配置参数相同且参数名称4对应的配置参数相同,则网络设备确定该相同的参数名称2对应的配置参数以及该相同的参数名称4对应的配置参数为N个配置参数。
下面以两个参考信号为例进行举例说明:
如果两个参考信号的配置信息包括:周期和时隙偏移值,参考信号1和参考信号2的配置信息中包括相同的周期,则第一信息包括相同的周期,如图6所示,相同的周期为5个时隙,参考信号1的第二信息包括参考信号1的时隙偏移值(0个时隙),参考信号2的第二信息包括参考信号2的时隙偏移值(3个时隙)。相应地,终端设备可以根据第一信息以及参考信号1的第二信息确定参考信号1的配置信息包括周期为5个时隙以及时隙偏移值为0个时隙,根据第一信息以及参考信号2的第二信息确定参考信号2的配置信息包括周期为5个时隙以及时隙偏移值为3个时隙。
如果两个参考信号的配置信息包括:周期、时隙偏移值、占用的频域资源位置,参考信号1和参考信号2的配置信息中包括相同的占用的频域资源位置,则第一信息包括相同的占用的频域资源位置,如图7所示,占用的频域资源位置为RB0-RB100,参考信号1的第二信息包括周期(20个时隙)和时隙偏移值(0个时隙),参考信号2的第二信息包括周期(40个时隙)和时隙偏移值(5个时隙)。相应地,终端设备可以根据第一信息以及参考信号1的第二信息确定参考信号1的配置信息包括占用的频域资源位置为RB0-RB100、周期为20个时隙以及时隙偏移值为0个时隙,根据第一信息以及参考信号2的第二信息确定参考信号2的配置信息包括占用的频域资源位置为RB0-RB100、周期为40个时隙以及时隙偏移值为5个时隙。
以参考信号为CSI-RS为例,相关技术中,CSI-RS的配置信是通过NZP-CSI-RS-Resource来配置的,如下所示:
Figure PCTCN2021071468-appb-000001
Figure PCTCN2021071468-appb-000002
其中,
● nzp-CSI-RS-ResourceId为CSI-RS资源的索引值;
● resourceMapping为CSI-RS的频域位置指示;
● powerControlOffset和powerControlOffsetSS为CSI-RS发送功率偏移值指示;
● scramblingID为CSI-RS的扰码ID,用于生成CSI-RS使用的随机序列;
● periodicityAndOffset为CSI-RS的时域周期以及偏移值;
● qcl-InfoPeriodicCSI-RS为周期性CSI-RS的准共位置(quasi-colocation,QCL)信息。
以参考信号为CSI-RS为例,相关技术中,CSI-RS的配置信息通过CSI-RS-ResourceConfigMobility来配置的,如下所示
Figure PCTCN2021071468-appb-000003
Figure PCTCN2021071468-appb-000004
其中,
● cellId为小区ID;
● csi-rs-MeasurementBW为CSI-RS的测量带宽,其中,nrofPRBs为PRB个数,即占用的频域资源宽度,startPRB为PRB起始位置,即占用的频域资源起始位置
● density为频域密度;
● csi-rs-ResourceList-Mobility为用于移动性测量的CSI-RS资源列表,其中包含多个CSI-RS-Resource-Mobility,每个CSI-RS-Resource-Mobility为一个CSI-RS资源的配置信息;
● csi-RS-Index为CSI-RS资源的索引值;
● slotConfig为CSI-RS的时域资源指示,举例来说,ms4表示周期为4ms,其后的取值INTEGER(0..31)表示时域偏移值为0~31个时隙中的某一个;ms5表示周期为5ms,其后的取值INTEGER(0..39)表示时域偏移值为0~39个时隙中的某一个,以此类推;
● associatedSSB为关联的同步信号和PBCH块(synchronization signal and PBCH block,SSB)的指示,其中ssb-Index为SSB的索引值,isQuasiColocated指示是该CSI-RS与该SSB是否QCL的;
● frequencyDomainAllocation为CSI-RS的频域位置指示;
● firstOFDMSymbolInTimeDomain为CSI-RS占用的第一个OFDM符号位置;
● sequenceGenerationConfig为用于生成CSI-RS使用的随机序列的配置信息。
由上述可知,本申请实施例中,参考信号的配置信息通过类似NZP-CSI-RS-Resource的形式以及类似CSI-RS-ResourceConfigMobility的形式来配置 时配置参数的表示形式可能不同。以配置参数为占用的频域资源位置为例,当参考信号的配置信息通过类似NZP-CSI-RS-Resource的形式配置时表示为resource mapping。当参考信号的配置信息通过类似CSI-RS-ResourceConfigMobility的形式配置时表示为nrofPRBs和startPRB。
本实施例中,通过第一信息来指示多个参考信号中相同的配置参数,这样每个第二信息中可以无需指示与其它参考信号的配置信息中相同的配置参数,这样相同的配置参数通过一个信息来指示,无需通过多个信息来指示,从而降低了广播信息的信令开销。
在一些实施例中,上述N个配置参数相当于是参考配置参数,M i个配置参数为第i个参考信号的配置信息中与N个配置参数中不同的配置参数。
其中,Q i的值等于N的值,第一信息中的N个配置参数与M i个配置参数包含相同参数名称的配置参数。例如N个配置参数中包括周期,M i个配置参数中也包括周期,N个配置参数中周期(比如20个时隙)与M i个配置参数中周期(比如40个时隙)不相同。
可选的,上述S503的一种可能的实现方式为:终端设备根据所述第i个第二信息,确定所述Q i个配置参数中M i个配置参数;以及根据所述N个配置参数中除参数名称与所述M i个配置参数相同的配置参数,确定所述Q i个配置参数中除M i个配置参数之外的配置参数。
本实施例中,终端设备根据第i个第二信息,确定M i个配置参数,并将该M i个配置参数确定为第i个参考信号的M i个配置参数。终端设备根据第一信息,确定N个配置参数。由于N个配置参数与M i个配置参数存在参数名称相同的配置参数,N个配置参数中的这些配置参数不属于第i个参考信号的配置信息,所以终端设备将N个配置参数中除参数名称与所述M i个配置参数相同的配置参数,确定为第i个参考信号的配置信息中除M i个配置参数之外的配置参数。
需要说明的是,当M i等于0时,第i个第二信息是一个空的信息,表示第i个参考信号的配置信息即为第一信息指示的N个配置参数。当M i的值等于N的值时,表示第i个参考信号的配置信息包括M i个配置参数且不包括第一信息指示的N个配置参数中的任一个。
本实施例中,通过第一信息来指示的N个配置参数作为参考配置参数,第二信息用于指示参考信号的配置信息中与N个配置参数不同的配置参数,这样每个第二信息中可以无需指示与参考配置参数中相同的配置参数,从而降低了广播信息的信令开销。
可选的,第一信息包括N个配置参数。
可选的,第一信息包括参考配置信息的标识信息,所述参考配置信息包括所述N个配置参数。本实施例中,标识信息与配置信息存在对应关系,该对应关系可以预先设置,终端设备接收到第一信息后,根据第一信息中的标识信息,确定该标识信息对应的配置信息,并将该配置信息作为参考配置信息,将该配置信息中的各配置参数确定为N个配置参数。该标识信息例如为索引号。
因此,本实施例通过标识信息来指示N个配置参数,标识信息占用的比特位更少,进一步节省广播信息的信令开销。
其中,第i个第二信息指示M i个配置参数可以包括如下两种可能的实现方式。
在一种可能的实现方式中,第i个第二信息包括M i个配置参数。相应地,终端设备根据所述第i个第二信息,确定所述Q i个配置参数中M i个配置参数可以是:终端设备将第i个第二信息中的M i个配置参数确定为所述Q i个配置参数中的M i个配置参数。
其中,上述的广播信息可以包括如下例子:
Figure PCTCN2021071468-appb-000005
其中,
● BroadcastedResourceSet为广播的参考信号资源集合;
● nzp-CSI-ResourceSetId为资源集合的索引值;
● referenceConfiguration为参考配置,其中包含一个NZP-CSI-RS-Resource,即一个CSI-RS资源的配置信息;
● Resources包含多个(即K个)NZP-CSI-RS-Resource,每个NZP-CSI-RS-Resource为一个CSI-RS资源的配置信息,即Resources分别指示了各个参考信号的配置信息。
其中,上述的referenceConfiguration表示为第一信息。Resources中包括多个第二信息。
如果Resources中某个NZP-CSI-RS-Resource(第二信息的内容)是空的,则表示该第二信息对应的参考信号的配置信息完全复用referenceConfiguration中的配置参数;如果Resources中某个NZP-CSI-RS-Resource中包含某个配置参数,该配置参数的取值与referenceConfiguration中的参数取值不同,则该资源使用该Resources中NZP-CSI-RS-Resource中配置的值。
以每个参考信号的配置信息包括周期和时隙偏移值为例,第一信息包括:周期为20个时隙,时隙偏移值是0个时隙。如果第1个参考信号的第二信息包括时隙偏移值是5个时隙,就意味着,第1个参考信号的配置信息包括周期为20个时隙,时隙偏移值是5个时隙。
在本实施例中,也可以理解为终端设备首先根据第一信息确定参考配置信息,然后使用第i个第二信息中指示的配置参数替换/改写(replace/override/overwrite)参考配置信息中参数名称相同的配置参数,以得到第i个参考信号的配置信息。仍以上述例子为例,第一信息包括:周期为20个时隙,时隙偏移值是0个时隙。如果第1个参考信号的第二信息包括时隙偏移值是5个时隙。终端设备可以首先确定参考配置为“周期为20个时隙,时隙偏移值是0个时隙”,然后使用第1个参考信号的配置信息中包括的“时隙偏移值是5个时隙”,来替换参考配置信息中的“时隙偏移值是0个时隙”,最终确定第1个参考信号的配置信息为“周期为20个时隙,时隙偏移值是5个时隙”。
在另一种可能的实现方式中,第i个第二信息包括M i个配置参数的偏移值,第i 个第二信息中第一参数名称的配置参数的偏移值为Q i个配置参数中第一参数名称的配置参数相对于N个配置参数中第一参数名称的配置参数的偏移值,第一参数名称为N个配置参数与M i个配置参数中的任一相同参数名称。以第一参数名称是周期为例,如果N个配置参数中周期为20个时隙,M i个配置参数中周期为40个时隙,相应地,该第i个第二信息中包括周期的偏移值为20个时隙。
相应地,终端设备根据第i个第二信息,确定Q i个配置参数中M i个配置参数可以是:终端设备根据第i个第二信息中第一参数名称的配置参数的偏移值和N个配置参数中所述第一参数名称的配置参数,确定第i个参考信号的第一参数名称的配置参数。
如果M i个配置参数与N个配置参数中相同参数名称的为周期和时隙偏移值,例如:N个配置参数中周期为20个时隙,时隙偏移值为0个时隙,第二信息包括:周期的偏移值为20个时隙,时隙偏移值的偏移值为5个时隙。相应地,终端设备获得的M i个配置参数为周期为40个时隙,时隙偏移值为5个时隙。
本实施例,通过配置参数的偏移量来指示配置参数,偏移值与配置参数相比,占用的比特数更少,进一步降低广播信息的信令开销。例如,假设“时隙偏移值”本身的取值范围为0~19,则需要5个比特才能指示。如果使用偏移量来指示,并且认为一个参考信号的时隙偏移值相对于“N个配置参数中的时隙偏移值”相差不会超过±5个时隙,则需要4个比特就可以表示,从而节省了1个比特。
在本实施例中,相同参数名称可以是名称完全相同,也可以是名称不完全相同但是用于指示同一个参数的取值。例如,第一信息中的参数名为periodicity(即周期),第二信息中的参数名为periodicityOffset或periodicityDelta(即周期的偏移值)。这种两个参数的参数名并不完全相同,但是目的都是确定同一个参数(即周期)的情况,也可以被认为是相同参数名称。
需要说明的是,当M i等于0时,第i个第二信息是一个空的信息,表示第i个参考信号的配置信息与第一信息指示的N个配置参数完全相同。
在一些实施例中,如果Q i的值等于N的值,网络设备可以从多个参考信号的配置信息中确定一个参考信号的配置信息中的配置参数为N个配置参数,剩下的参考信号的配置信息分别用于生成对应的第二信息。相应地,终端设备还可以根据第一信息确定第K+1个参考信号的配置信息。也就是终端设备根据第一信息确定N个配置参数,然后根据N个配置参数确定第K+1个参考信号的配置信息。
可选的,所述第K+1个参考信号的配置信息包括所述N个配置参数。比如终端设备将N个配置参数确定为第K+1个参考信号的配置信息。
因此,这种方式下,还可以增加网络设备广播的参考信号的配置信息的数量。
图8为本申请另一实施例提供的通信方法的流程图,如图8所示,本实施例的方法可以包括:
S801、网络设备生成广播信息。
S802、网络设备发送广播信息。相应地,终端设备接收网络设备发送的广播信息。广播信息包括:第一信息和多个第二信息。
S803、当i等于1时,终端设备根据第一信息指示的部分或全部配置参数,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息;当i不等于1时,终 端设备根据第i-1个参考信号的配置信息,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息。
本实施例中,网络设备确定多个参考信号中每个参考信号的配置信息,以多个参考信号中第i个参考信号为例,i为大于等于1的整数,第i个参考信号的配置信息包括Q i个配置参数。网络设备还可以确定N个配置参数,网络设备根据N个配置参数生成第一信息,第一信息用于指示N个配置参数,N为大于等于1的整数。网络设备根据N个配置参数以及第1个参考信号的配置信息,确定M 1个配置参数,并根据M 1个配置参数确定第1个第二信息。网络设备根据第1个参考信号的配置信息以及第2个参考信号的配置信息,确定M 2个配置参数,并根据M 2个配置参数确定第2个第二信息。以此类推,共生成多个第二信息,第i个第二信息用于指示第i个参考信号的M i个配置参数。该多个第二信息分别对应多个参考信号。其中,Q i大于等于N,Q i大于等于M i。需要说明的是,当i的值不同时,M i的值也可能会不相同。
网络设备根据第一信息和多个第二信息,生成广播信息,该广播信息包括第一信息和多个第二信息,然后广播发送广播信息。相应地,一个或多个终端设备接收网络设备发送的广播信息。下面以其中一个终端设备接收广播信息后如何处理为例描述,其它终端设备类似,此处不再赘述。
终端设备接收到网络设备发送的广播信息后,终端设备根据第一信息指示的部分或全部配置参数,以及第1个第二信息指示的M 1个配置参数,确定第1个参考信号的配置信息,即i等于1。
终端设备根据第2个第二信息指示的M 2个配置参数以及第1个参考信号的配置信息,确定第2个参考信号的配置信息,即i等于2。
终端设备根据第3个第二信息指示的M 3个配置参数以及第2个参考信号的配置信息,确定第3个参考信号的配置信息,即i等于2。
以此类推,终端设备可以得到多个参考信号的配置信息。
可选的,上述参考信号可以是如下一种或多种:PSS、SSS、CSI-RS和TRS。
可选的,所述M i个配置参数包括如下一项或多项:周期、时隙偏移值、占用的OFDM符号位置、频域RE偏移值、端口数、CDM类型、频域密度、扰码ID、映射的起始RB、映射的RB数量。
本实施例的通信方法,网络设备发送广播信息,所述广播信息包括:第一信息和多个第二信息,所述第一信息用于指示N个配置参数,第i个第二信息用于指示第i个参考信号的M i个配置参数。一个或多个终端设备接收到广播信息后,当i等于1时,终端设备根据第一信息指示的部分或全部配置参数,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息;当i不等于1时,终端设备根据第i-1个参考信号的配置信息,以及第i个第二信息指示的M i个配置参数,确定第i个参考信号的配置信息,第i个参考信号的配置信息包括Q i个配置参数,Q i大于等于N,Q i大于等于M i。因此,终端设备并不是直接接收每个参考信号的配置信息,而是根据每个参考信号的第二信息以及相对应的配置参数,恢复出每个参考信号的配置信息,这样网络设备无需向终端设备直接发送每个参考信号的配置信息,可以节省广播信息的信令开销。另外,通过同一广播信息使终端设备获得更多数量的参考信号的配置信息。
在一些实施例中,上述N个配置参数相当于是第一个参考信号的参考配置参数,第1个参考信号的M 1个配置参数为第1个参考信号的配置信息中与N个配置参数中不同的配置参数。第i-1个参考信号的M i-1个配置参数相当于是第i个参考信号的参考配置参数,第i个参考信号的M i个配置参数为第i个参考信号的配置信息与第i个参考信号的配置信息中不同的配置参数。
其中,Q i的值等于N的值,当i等于1时,第一信息中的N个配置参数与M i个配置参数包含相同参数名称的配置参数。当i不等于1时,第i-1个参考信号的Q i-1个配置参数与M i个配置参数包含相同参数名称的配置参数。例如N个配置参数中包括周期,第1个参考信号的M 1个配置参数中也包括周期,N个配置参数中周期(比如20个时隙)与M 1个配置参数中周期(比如40个时隙)不相同。例如第1个参考信号的配置信息中包括时隙偏移值,第2个参考信号的M 2个配置参数中包括时隙偏移值,第1个参考信号的配置信息中的时隙偏移值(比如0个时隙)与第2个参考信号的M 2个配置参数中的时隙偏移值(比如5个时隙)不相同。
可选的,上述S803的一种可能的实现方式为:当i等于1时,终端设备根据所述第i个第二信息,确定所述Q i个配置参数中M i个配置参数;根据所述N个配置参数中的除参数名称与所述M i个配置参数相同的配置参数,确定所述Q i个配置参数中除M i个配置参数之外的配置参数。当i不等于1时,终端设备根据第i个第二信息,确定Q i个配置参数中M i个配置参数;根据第i-1个参考信号的Q i-1个配置参数中除参数名称与M i个配置参数相同的配置参数,确定Q i个配置参数中除M i个配置参数之外的配置参数。
本实施例中,当i等于1时,终端设备根据第1个第二信息,确定M 1个配置参数,并将该M 1个配置参数确定为第1个参考信号的M 1个配置参数。终端设备根据第一信息,确定N个配置参数。由于N个配置参数与M 1个配置参数存在参数名称相同的配置参数,N个配置参数中的这些配置参数不属于第1个参考信号的配置信息,所以终端设备将N个配置参数中除参数名称与M 1个配置参数相同的配置参数,确定为第1个参考信号的配置信息中除M 1个配置参数之外的配置参数。从而终端设备获得第1个参考信号的配置信息,包括Q 1个配置参数。
当i不等于1时,终端设备根据第2个第二信息,确定M 2个配置参数,并将该M 2个配置参数确定为第2个参考信号的M 2个配置参数。由于第1个参考信号的配置信息与M 2个配置参数存在参数名称相同的配置参数,第1个参考信号的配置信息中的这些配置参数不属于第2个参考信号的配置信息,所以终端设备将第1个参考信号的配置信息中除参数名称与M 2个配置参数相同的配置参数,确定为第2个参考信号的配置信息中除M 2个配置参数之外的配置参数。从而终端设备获得第2个参考信号的配置信息,包括Q 2个配置参数。
以此类推,获得各参考信号的配置信息。
本实施例中,通过第一信息来指示的N个配置参数作为参考配置参数,第1个第二信息用于指示第1个参考信号的配置信息中与N个配置参数不同的配置参数。以及通过第i-1个参考信号的配置信息作为参配置参数,第i个第二信息用于指示第i个参考信号的配置信息中与第i-1个参考信号的配置信息不同的配置参数。这样每个第二 信息中可以无需指示与相应参考配置参数中相同的配置参数,从而降低了广播信息的信令开销。
可选的,第一信息包括N个配置参数。
可选的,第一信息包括参考配置信息的标识信息,所述参考配置信息包括所述N个配置参数。本实施例中,标识信息与配置信息存在对应关系,该对应关系可以预先设置,终端设备接收到第一信息后,根据第一信息中的标识信息,确定该标识信息对应的配置信息,并将该配置信息作为参考配置信息,将该配置信息中的各配置参数确定为N个配置参数。该标识信息例如为索引号。
因此,本实施例通过标识信息来指示N个配置参数,标识信息占用的比特位更少,进一步节省广播信息的信令开销。
其中,第i个第二信息指示M i个配置参数可以包括如下两种可能的实现方式。
在一种可能的实现方式中,第i个第二信息包括M i个配置参数。相应地,终端设备根据所述第i个第二信息,确定所述Q i个配置参数中M i个配置参数可以是:终端设备将第i个第二信息中的M i个配置参数确定为所述Q i个配置参数中的M i个配置参数。
以每个参考信号的配置信息包括周期和时隙偏移值为例,第一信息包括:周期为20个时隙,时隙偏移值是0个时隙。如果第1个第二信息包括时隙偏移值是5个时隙,就意味着,第1个参考信号的配置信息包括周期为20个时隙,时隙偏移值是5个时隙。如果第2个第二信息包括周期为40个时隙,就意味着,第2个参考信号的配置信息包括周期为40个时隙,时隙偏移值是5个时隙。
在本实施例中,也可以理解为终端设备首先根据第一信息确定参考配置信息,然后使用第1个第二信息中指示的配置参数替换/改写(replace/override/overwrite)参考配置信息中参数名称相同的配置参数,以得到第1个参考信号的配置信息。将第1个参考信号的配置信息确定为参考配置信息,使用第2个第二信息中指示的配置参数替换/改写(replace/override/overwrite)参考配置信息中参数名称相同的配置参数,以得到第2个参考信号的配置信息。将第2个参考信号的配置信息确定为参考配置信息,使用第3个第二信息中指示的配置参数替换/改写(replace/override/overwrite)参考配置信息中参数名称相同的配置参数,以得到第3个参考信号的配置信息。以此类推,此处不再赘述。
在另一种可能的实现方式中,第i个第二信息包括M i个配置参数的偏移值。
当i等于1时,第i个第二信息中第一参数名称的配置参数的偏移值为Q i个配置参数中第一参数名称的配置参数相对于N个配置参数中第一参数名称的配置参数的偏移值,第一参数名称为N个配置参数与M i个配置参数中的任一相同参数名称。
当i不等于1时,第i个第二信息中第二参数名称的配置参数的偏移值为Q i个配置参数中第二参数名称的配置参数相对于第i-1个参考信号的Q i-1个配置参数中第二参数名称的配置参数的偏移值,第二参数名称为第i-1个参考信号的Q i-1个配置参数与M i个配置参数中的任一相同参数名称。
第一参数名称与第二参数名称是为了说明不同参考信号对应的相同参数名称不一定相同。以第一参数名称是周期为例,如果N个配置参数中周期为20个时隙,M 1个配置参数中周期为40个时隙,相应地,该第1个第二信息中包括周期的偏移值为20 个时隙。
以第二参数名称是时隙偏移值为例,如果第i-1参考信号的配置信息中的时隙偏移值为0个时隙,M i个配置参数中的时隙偏移值为5个时隙,相应地,该第i个第二信息中包括时隙偏移值的偏移值为5个时隙。
相应地,当i等于1时,终端设备根据第i个第二信息,确定Q i个配置参数中M i个配置参数可以是:终端设备根据第i个第二信息中第一参数名称的配置参数的偏移值和N个配置参数中所述第一参数名称的配置参数,确定第i个参考信号的第一参数名称的配置参数。具体实现过程可以参见上述实施例中的相关描述,此处不再赘述。
相应地,当i不等于1时,终端设备根据第i个第二信息,确定Q i个配置参数中M i个配置参数可以是:终端设备根据第i个第二信息中第二参数名称的配置参数的偏移值和第i-1个参考信号的Q i-1个配置参数中第二参数名称的配置参数,确定第i个参考信号的第二参数名称的配置参数。
如果第2个参考信号的M 2个配置参数与第1个参考信号的配置信息中相同参数名称的为周期,例如:第1个参考信号的配置信息中周期为20个时隙,时隙偏移值为0个时隙,第2个第二信息包括:周期的偏移值为20个时隙。相应地,终端设备获得的第2个参考信号的M 2个配置参数为周期为40个时隙,然后终端设备可获得第2个参考信号的配置信息包括:周期为40个时隙、时隙偏移值为0个时隙。如果第3个参考信号的M 3个配置参数与第2个参考信号的配置信息中相同参数名称的为时隙偏移值,第3个第二信息包括:时隙偏移值的偏移值为5个时隙。相应地,终端设备获得的第3个参考信号的M 3个配置参数为时隙偏移值为5个时隙,然后终端设备可获得第3个参考信号的配置信息包括:周期为40个时隙、时隙偏移值为5个时隙。
本实施例,通过配置参数的偏移量来指示配置参数,偏移值与配置参数相比,占用的比特数更少,进一步降低广播信息的信令开销。例如,假设“时隙偏移值”本身的取值范围为0~19,则需要5个比特才能指示。如果使用偏移量来指示,并且认为一个参考信号的时隙偏移值相对于“N个配置参数中的时隙偏移值”相差不会超过±5个时隙,则需要4个比特就可以表示,从而节省了1个比特。
在本实施例中,相同参数名称可以是名称完全相同,也可以是名称不完全相同但是用于指示同一个参数的取值。例如,第一信息中的参数名为periodicity(即周期),第二信息中的参数名为periodicityOffset或periodicityDelta(即周期的偏移值)。这种两个参数的参数名并不完全相同,但是目的都是确定同一个参数(即周期)的情况,也可以被认为是相同参数名称。
需要说明的是,当M i等于0时,第i个第二信息是一个空的信息,表示第i个参考信号的配置信息与第一信息指示的N个配置参数完全相同。
在一些实施例中,如果Q i的值等于N的值,网络设备可以从多个参考信号的配置信息中确定一个参考信号的配置信息中的配置参数为N个配置参数,剩下的参考信号的配置信息分别用于生成对应的第二信息。相应地,终端设备还可以根据第一信息确定第K+1个参考信号的配置信息。也就是终端设备根据第一信息确定N个配置参数,然后根据N个配置参数确定第K+1个参考信号的配置信息。
可选的,所述第K+1个参考信号的配置信息包括所述N个配置参数。比如终端设 备将N个配置参数确定为第K+1个参考信号的配置信息。
因此,这种方式下,还可以增加网络设备广播的参考信号的配置信息的数量。
图9为本申请另一实施例提供的通信方法的流程图,如图9所示,本实施例的方法可以包括:
S901、网络设备生成广播信息。
S902、网络设备发送广播信息。相应地,终端设备接收网络设备发送的广播信息。广播信息包括K个参考信号的配置信息的标识信息。
S903、终端设备根据K个标识信息分别确定对应的K个参考信号的配置信息。
本实施例中,网络设备确定K个参考信号中每个参考信号的配置信息,K为大于等于1的整数。网络设备根据K个参考信号的配置信息分别获取K个标识信息,其中,每个标识信息一一对应一个参考信号的配置信息。网络设备根据K个标识信息,生成广播信息。该广播信息包括K个标识信息。相应地,一个或多个终端设备接收网络设备发送的广播信息。下面以其中一个终端设备接收广播信息后如何处理为例描述,其它终端设备类似,此处不再赘述。
终端设备接收到网络设备发送的广播信息后,确定K个标识信息分别确定对应的K个参考信号的配置信息。
可选的,上述参考信号可以是如下一种或多种:PSS、SSS、CSI-RS和TRS。
可选的,每个参考信号的配置信息包括如下一项或多项:周期、时隙偏移值、占用的OFDM符号位置、频域RE偏移值、端口数、CDM类型、频域密度、扰码ID、映射的起始RB、映射的RB数量。
在一些实现方式中,终端设备和网络设备预先设置有参考信号的配置信息与标识信息的对应关系,也就是会预先定义有多个参考信号的配置信息,并为每个参考信号的配置信息分配有标识信息。所以网络设备从预先定义的多个参考信号的配置信息中确定K个参考信号的配置信息,然后根据预设的参考信号的配置信息与标识信息的对应关系,确定K个参考信号的配置信息分别对应的标识信息。相应地,终端设备从广播信息中获得K个标识信息后,根据预设的参考信号的配置信息与标识信息的对应关系,确定K个标识信息分别对应的参考信号的配置信息。
可选的,上述标识信息为索引号。
本实施例的通信方法,通过网络设备发送广播信息,广播信息包括K个标识信息。一个或多个终端设备接收到广播信息后,根据K个标识信息分别确定对应的K个参考信号的配置信息。因此,终端设备并不是直接接收每个参考信号的配置信息,而是根据接收的标识信息,确定出每个参考信号的配置信息,这样网络设备无需向终端设备直接发送每个参考信号的配置信息,可以节省广播信息的信令开销,还可以通过广播信息使终端设备获得更多参考信号的配置信息。
需要说明的是,上述任一实施例可以单独实施,也可以是上述各实施例中至少两个任意结合来实施,对此不做限定。

在具体实现中,本申请上述各实施例例如可以应用于如下场景:
用户使用手机,在手机开机时,手机发起随机接入以接入网络(即进入连接态),并且在连接态接收网络设备下发的参考信号配置信息,该参考配置信息用于配置一些参考信号资源。若手机开机后,一段时间内没有业务传输,网络设备会指示手机转入非连接态(如非激活态,或空闲态),之后,手机需要在PO的位置接收寻呼消息。为了减少手机的功耗浪费,手机可以在转入非连接态时仍然存储上述参考信号配置信息,并且根据参考信号配置信息从网络设备接收对应的参考信号,以进行时频同步、AGC调整等。其中,手机接收对应的参考信号的配置信息时,即可以使用本发明方案中各个实施例的方案,从而减低信令开销。
