当网络设备采用波束扫描方式发送寻呼消息时,对于每个寻呼周期,网络设备可以发送多个同步信号块(Synchronous Signal Block,SSB)信号(或称为SSB busrt),每个SSB关联1个寻呼监听位置,在特定SSB对应特定的寻呼监听位置接收寻呼消息。比如,网络设备广播SSB1、SSB2和SSB3,对应寻呼的物理下行控制信道(Physical Downlink Control Channel,PDCCH)监听机会1、监听机会2和监听机会3;当UE在其PO位置检测到SSB1时,UE在SSB1对应的PDCCH监听机会1接收寻呼消息的调度信息,并借助接收到的调度信息实现接收寻呼消息。
请参见图1,图1是本公开实施例提供的一种数据接收方法的流程图,该方法应用于终端,如图1所示,该方法包括如下步骤:
步骤101:接收寻呼消息。
步骤102:在所述寻呼消息中包括指示具有终端的下行数据发送的指示信息情况下,获取所述终端的下行数据。
需说明的是,本实施例中的终端可选为在空闲态(IDLE)或者非激活态(INACTIVE)。上述寻呼消息可为特定寻呼消息,与相关技术中的寻呼消息采用不同的配置信息。上述下行数据可选为数据无线承载(Data Radio Bearer,DRB)数据。
可选的,上述指示具有终端的下行数据发送的指示信息可以是终端的标识信息,比如I-RNTI或ng-5G-S-TMSI,也可以是比如1bit指示信息,当该指示信息为1时,表示有该终端的下行数据发送。
可选的,上述寻呼消息可以由指示下行数据发送的标识信息标识。比如,该标识信息可选为P-Data-RNTI,对应寻呼消息是通过P-Data-RNTI标识的调度信息调度发送。
可选的,为了实现正常接收寻呼消息和相应下行数据,上述步骤101之前,终端还可从网络设备接收寻呼消息配置信息,以及与该寻呼消息配置信息关联的下行数据接收的配置信息。比如,UE接收小区1的系统信息SIB8,该SIB8中包含了特定的寻呼消息配置信息(如,pagingForDataConfig),以及与该特定的寻呼消息配置信息关联的下行数据接收的配置信息(如,dataConfig)。可理解的,该特定的寻呼消息配置信息是相对于相关技术中的普通的不用于数据发送的寻呼消息配置信息(如,pagingConfig)而言的,两者采用不同的配置信息。
可选的,上述下行数据接收的配置信息可以包括以下至少一项:
是否通过寻呼消息关联发送下行数据的指示信息;比如,该指示信息可选为1bit,取值为0或1,当取值为1时表示寻呼消息会与下行数据在同1个MAC PDU中发送,而当取值为0时表示寻呼消息会不与下行数据在同1个MAC PDU中发送。
寻呼消息的标识信息。需说明的是,此寻呼消息的标识信息指的是本实施例中特定寻呼消息的标识信息,比如P-Data-RNTI,不同于相关技术中的不用于数据发送的寻呼消息的标识信息(如P-RNTI)。
为了便于终端解码获得对应的下行数据,在获取下行数据之前,终端还可恢复使用其用于下行数据接收的配置信息。比如,该用于下行数据接收的配置信息可选为安全算法、安全秘钥、DRB配置信息等。
本公开实施例的数据接收方法,接收寻呼消息,在该寻呼消息中包括指示具有终端的下行数据发送的指示信息的情况下,获取该终端的下行数据,可以实现当终端在空闲态或非激活态时,网络设备将相应下行数据直接发送给该终端,从而减少下行数据的发送延时。
本公开实施例中,为了使得网络设备获知终端的数据接收情况,在获取下行数据之后,终端还可向网络设备发送反馈信息。其中,该反馈信息可包括但不限于以下至少一项:
是否成功接收了下行数据的指示信息。比如,该指示信息可通过以下任意一项反馈:混合自动重传请求(Hybrid ARQ,Hybrid Automatic Repeat Request,HARQ)确认(Acknowledgement,ACK)信息、物理随机接入信道(Physical Random Access Channel,PRACH)资源、物理上行控制信道(Physical Uplink Control Channel,PUCCH)的调度请求(Scheduling Request,SR)信息等。
是否有上行数据发送的指示信息。比如,该指示信息可通过发送缓存状态报告(Buffer Status Report,BSR)信息反馈给网络侧。
可选的,上述反馈信息的发送资源可以是由网络设备指示的,而指示方式可以包括以下任意一种:
通过寻呼(paging)消息中的指示信息指示。比如,在paging消息中下发该反馈信息的发送资源的配置信息。
通过系统信息指示。比如,在系统信息中指示下行数据接收对应的反馈信息的发送资源。
本公开实施例中,上述终端的下行数据可以与寻呼消息同时发送,也可以在与寻呼消息关联的下行数据发送位置上发送,即与寻呼消息分开发送。对此分别说明如下。
情况一
情况一下,终端的下行数据和寻呼(paging)消息可以同时在1个介质访问控制(Media Access Control,MAC)层协议数据单元(Protocol Data Unit,PDU)中发送。其中,此MAC PDU可为Physical Downlink Shared Channel(物理下行共享信道,PDSCH)中的传输内容,即终端的下行数据和寻呼消息可以同时在1个PDSCH中发送。
此情况一下,为了实现正常接收寻呼消息和相应下行数据,上述步骤101之前,终端还可从网络设备接收寻呼消息配置信息,以及与该寻呼消息配置信息关联的下行数据接收的配置信息。比如,UE接收小区1的系统信息SIB8,该SIB8中包含了特定的寻呼消息配置信息(如,pagingForDataConfig),以及与该特定的寻呼消息配置信息关联的下行数据接收的配置信息(如,dataConfig)。可理解的,该特定的寻呼消息配置信息是相对于相关技术中的 普通的不用于数据发送的寻呼消息配置信息(如,pagingConfig)而言的,两者采用不同的配置信息。
可选的,上述下行数据接收的配置信息可以包括以下至少一项:
是否通过寻呼消息关联发送下行数据的指示信息;比如,该指示信息可选为1bit,取值为0或1,当取值为1时表示寻呼消息会与下行数据在同1个MAC PDU中发送,而当取值为0时表示寻呼消息会不与下行数据在同1个MAC PDU中发送。
寻呼消息的标识信息。需说明的是,此寻呼消息的标识信息指的是本实施例中特定寻呼消息的标识信息,比如P-Data-RNTI,不同于相关技术中的不用于数据发送的寻呼消息的标识信息(如P-RNTI)。
这样,借助此下行数据接收的配置信息,可以使得终端通过寻呼消息来接收相应下行数据。
需说明的是,由于本实施例中要实现对在INACTIVE或IDLE态下的终端发送下行数据,因此为了保证终端接收数据,网络设备还可向终端发送配置信息,该配置信息用于指示终端在INACTIVE或IDLE态时保存下行数据接收的配置信息。其中该下行数据接收的配置信息可包括以下至少一项:下行数据接收的DRB标识(如,UE下行数据通过DRB1发送)、下行数据通过控制面信令接收的指示信息(如,UE下行数据通过在下行无线资源控制(Radio Resource Control,RRC)消息中携带)。
一种实施方式中,当UE1在连接态的时候,基站1可发送RRC释放(RRC Release)消息给UE1,以指示UE1进入INACTIVE态,同时指示UE保存用于下行数据接收的配置信息。
此情况一下,上述步骤102中的获取终端的下行数据可以包括:
按照预设数据格式,从发送寻呼消息的MAC层PDU中,解码获得所述终端的下行数据。
其中,上述预设数据格式可选为以下任意一项:
数据格式1:MAC层PDU中包括一个终端的下行数据;比如,MAC层PDU中仅包括一个终端的下行数据;
数据格式2:MAC层PDU中包括多个终端的下行数据。
对于上述数据格式1,参见图2A所示,该一个终端的下行数据(data)可排列在该寻呼消息(Paging)之后。此外如图2A所示,上述数据格式1还可以额外包含以下内容:
1)寻呼消息对应的寻呼消息头(如,Paging Header),该寻呼消息头中可包含指示对应寻呼消息的长度的指示信息。比如,该指示信息指示的应寻呼消息的长度L可等于10byte。
2)终端数据对应的数据头(如,Data Header),该数据头中可包含指示对应终端数据的长度的指示信息。比如,该指示信息指示的对应终端数据的长度L可等于10byte。
对于上述数据格式2,参见图2B和图2C所示,该多个终端的下行数据(data)可以按照寻呼消息(Paging)中指示的终端顺序(此终端顺序可为终端标识的顺利),按序排列在该寻呼消息之后。比如图2B所示,若寻呼消息中指示有数据发送的UE标识包括UE1和UE2,则该寻呼消息之后紧跟UE1数据,而UE1数据之后紧跟UE2数据。
此外如图2B所示,上述数据格式2还可以额外包含以下内容:
1)寻呼消息对应的寻呼消息头(如,Paging Header),该寻呼消息头中可包含指示对应寻呼消息的长度的指示信息。比如,该指示信息指示的应寻呼消息的长度L可等于10byte;
2)终端数据对应的数据头(如,Data Header),该数据头中可包含指示对应终端数据的长度的指示信息。比如,该指示信息指示的对应终端数据的长度L可等于10byte。
或者,如图2C所示,上述数据格式2还可以额外包含以下内容:
1)寻呼消息对应的寻呼消息头(如,Paging Header),该寻呼消息头中可包含指示对应寻呼消息的长度的指示信息。比如,该指示信息指示的对应寻呼消息的长度L可等于10byte;
2)终端数据对应的数据头(如,Data Header),该数据头中可包含指示对应终端数据的长度的指示信息(如该指示信息指示的终端数据的长度L可等于10byte),以及终端标识指示信息(或称为终端标识信息),如图2C中的ID1和ID2;其中该ID1比如为逻辑信道1,对应寻呼消息中的UE-ID-1;而 该ID2比如为逻辑信道2,对应寻呼消息中的UE-ID-2。
需说明的是,上述终端标识可以为隐式指示,或者显式指示。在隐式指示的情况下,终端标识信息可选为以下任意一项:截短的部分终端标识信息、根据终端标识计算得到的标识信息、终端标识对应逻辑信道标识信息(如,paging消息中第1个指示的终端标识对应逻辑信道标识1;paging消息中第2个指示的终端标识对应逻辑信道标识2)等。而在显式指示的情况下,终端标识信息直接指示终端标识。
一种实施方式中,对于已接收寻呼消息配置信息以及与该寻呼消息配置信息关联的下行数据接收的配置信息的UE,当该UE需要接收下行数据时,可以监听寻呼消息(即本实施例中的特定寻呼消息)的发送,比如通过监听P-Data-RNTI的PDCCH获取该寻呼消息的调度信息。若UE监听到P-Data-RNTI的PDCCH有调度该寻呼消息的发送,则UE可接收该寻呼消息;进一步若该寻呼消息中包含了UE标识(如,I-RNTI或ng-5G-S-TMSI),或指示有该UE的下行数据接收的指示信息,则UE解码其对应的下行数据。
情况二
情况二下,终端的下行数据可以通过与寻呼(paging)消息关联的下行资源(如,物理下行共享信道(Physical Downlink Shared Channel,PDSCH)信道)发送。
此情况二下,为了实现正常接收寻呼消息和相应下行数据,上述步骤101之前,终端还可从网络设备接收寻呼消息配置信息,以及与该寻呼消息配置信息关联的下行数据接收的配置信息。比如,UE接收小区1的系统信息SIB8,该SIB8中包含了特定的寻呼消息配置信息(如,pagingForDataConfig),以及与该特定的寻呼消息配置信息关联的下行数据接收的配置信息(如,dataConfig)。可理解的,该特定的寻呼消息配置信息是相对于相关技术中的普通的不用于数据发送的寻呼消息配置信息(如,pagingConfig)而言的,两者采用不同的配置信息。
可选的,上述下行数据接收的配置信息可以包括以下至少一项:
下行数据发送的资源配置信息。
下行数据发送的标识信息。
一种实施方式中,对于下行数据发送的资源配置信息,paging消息调度信息的资源位置可为10ms周期中的子帧1,则相应下行数据调度信息的资源位置可为10ms周期中的子帧2。这样在该子帧2,终端可接收下行数据调度信息,并基于接收到的下行数据调度信息来接收下行数据。
另一种实施方式中,对于下行数据发送的资源配置信息,paging消息调度信息的资源位置可为10ms周期中有1次PO(Paging Occasion),而该PO有S个PDCCH监听位置对应于1个SSB burst中的S个传输的SSB,其中该PO的S个PDCCH监听位置中的第K个paging的PDCCH监听位置对应于第K个传输的SSB。则更进一步的,该1个SSB burst的S个传输的SSB对应于S个下行数据的调度信息发送位置,第K个下行数据的PDCCH监听位置对应于第K个传输的SSB。比如,UE1的1个PO有3个PDCCH监听位置对应于3个SSB,该3个SSB对应于3个下行数据的PDCCH监听位置;当UE1下行检测到SSB-1时,UE1可在PDCCH(paging)-1的位置进行paging消息的接收,在PDCCH(data)-1的位置进行下行数据的接收。
另一种实施方式中,上述下行数据发送的标识信息可为下行数据的PDCCH调度信息的标识,比如Data-RNTI。其中,该下行数据的PDCCH调度信息的标识可以为多个,比如多个Data-RNTI。对于paging消息中指示有下行数据发送的多个UE,可以不同UE对应于不同的下行数据发送的标识信息。比如,按照paging消息中指示的有数据发送的多个UE排列顺序依次分配多个下行数据发送的标识信息。比如,系统消息中指示的下行数据发送的标识信息排列顺序为:Data-RNTI-1;Data-RNTI-2;Paging消息中指示有数据发送的UE标识信息排列顺序为:UE-ID-1;UE-ID-2;则,UE-ID-1对应的下行数据发送的标识信息为Data-RNTI-1;UE-ID-2对应的下行数据发送的标识信息为Data-RNTI-2。
需说明的是,由于本实施例中要实现对在INACTIVE或IDLE态下的终端发送下行数据,因此为了保证终端接收数据,网络设备还可向终端发送配置信息,该配置信息用于指示终端在INACTIVE或IDLE态时保存下行数据接收的配置信息。其中该下行数据接收的配置信息可包括以下至少一项:下行数据接收的DRB标识(如,UE下行数据通过DRB1发送)、下行数据通过 控制面信令接收的指示信息(如,UE下行数据通过在下行RRC消息中携带)。
一种实施方式中,当UE1在连接态的时候,基站1可发送RRC释放(RRC Release)消息给UE1,以指示UE1进入INACTIVE态,同时指示UE保存用于下行数据接收的配置信息。
此情况二下,上述步骤102中的获取终端的下行数据可以包括:
在与寻呼消息关联的下行数据接收位置上,接收所述终端的下行数据。
可理解的,对于同一下行数据,下行数据发送位置和下行数据接收位置是同一位置,因为相对的主体不同而采用的不同说法;对于网络设备为下行数据发送位置,而对于终端为下行数据接收位置。
可选的,在与寻呼消息关联的下行数据接收位置上具有多个终端的下行数据接收的情况下,上述接收所述终端的下行数据可包括:
通过以下任意一种信息,在与所述寻呼消息关联的下行数据接收位置上,接收所述终端的下行数据:
区分不同终端的下行数据的标识信息;比如,时隙slot-1同时有UE-1和UE-2的下行数据的调度信息发送,则,Data-RNTI-1用于UE-1的下行数据调度信息的发送,Data-RNTI-2用于UE-2的下行数据调度信息的发送,即通过不同的标识区分不同的UE数据。
区分不同终端的下行数据的预设数据包格式。
可选的,上述预设数据包格式可为以下任意一种:
数据包格式1:在各个终端的数据的数据头中包括终端标识信息;
数据包格式2:各个终端的数据按照寻呼消息中指示的终端顺序排列。
对于上述数据包格式1,参见图3A所示,各个终端的数据(data)具有其对应的数据头(如,Data Header),该数据头可称为数据包头,该数据头中可包含指示对应终端数据的长度的指示信息(如该指示信息指示的终端数据的长度L可等于10byte),以及终端标识信息,如图3A中的ID1和ID2;其中该ID1比如为逻辑信道1,对应寻呼消息中的UE-ID-1;而该ID2比如为逻辑信道2,对应寻呼消息中的UE-ID-2。
需说明的是,上述终端标识信息可以为隐式指示,或者显式指示。在隐式指示的情况下,终端标识信息可选为以下任意一项:截短的部分终端标识 信息、根据终端标识计算得到的标识信息、寻呼消息中指示有数据发送的终端标识的编号顺序(如,paging消息中第1个指示有数据发送的终端的标识为数值1;paging消息中第2个指示有数据发送的终端的标识为数值2)、终端标识对应逻辑信道标识信息(如,paging消息中第1个指示的终端标识对应逻辑信道标识1;paging消息中第2个指示的终端标识对应逻辑信道标识2)等。而在显式指示的情况下,终端标识信息直接指示终端标识。
对于上述数据包格式2,参见图3B所示,各个终端的数据(data)具有其对应的数据头(如,Data Header),该数据头中可包含指示对应终端数据的长度的指示信息,比如,该指示信息指示的终端数据的长度L可等于10byte。如图3B所示,paging消息中指示有数据发送的UE标识包括UE1和UE2,则第1个数据对应UE1的数据,UE1的数据后紧跟UE2的数据。
此情况二下,上述步骤102之前,所述方法还可包括:
向网络设备发送上行指示信息。
其中,该上行指示信息可指示终端的位置,以便网络设备根据该终端的位置向该终端发送下行数据。比如,该上行指示信息可指示终端发送该上行指示信息所在的小区。这样,网络设备在向该终端发送下行数据,可以通过该上行指示信息所指示的小区,将对应的下行数据发送给该终端。
或者,该上行指示信息可通知网络设备其接收到了寻呼消息,以便网络设备通过终端发送该上行指示信息的位置(如,小区)向终端发送下行数据。
可选的,上述上行指示信息的发送资源位置可以与寻呼(paging)消息关联。比如,paging消息调度信息的资源位置为10ms周期中的子帧1,则该上行指示信息的资源位置可为10ms周期中的子帧2。这样在该子帧2,终端可发送相应上行指示信息。又比如,paging消息调度信息的资源位置可为10ms周期中有1次PO(Paging Occasion),而该PO有S个PDCCH监听位置对应于1个SSB burst中的S个传输的SSB,其中该PO的S个PDCCH监听位置中的第K个paging的PDCCH监听位置对应于第K个传输的SSB。则更进一步的,该1个SSB burst的S个传输的SSB对应于S个上行指示信息发送位置,第K个上行指示信息发送位置对应于第K个传输的SSB。比如,UE1的1个PO有3个PDCCH监听位置对应于3个SSB,该3个SSB对应于3个上 行指示信息发送位置;当UE1下行检测到SSB-1时,UE1可在PDCCH(paging)-1的位置进行paging消息的接收,在PRACH(data)-1的位置进行上行指示信息的发送。
可选的,上述上行指示信息对应的信道可以为以下任意一项:
物理随机接入信道(Physical Random Access Channel,PRACH);
物理上行共享信道(Physical Uplink Shared Channel,PUSCH);
物理上行控制信道(Physical Uplink Control Channel,PUCCH);
探测参考信号(Sounding Reference Signal,SRS)。
可选的,上述上行指示信息可包括终端的标识信息,以便由网络设备区分不同终端。比如,在PUSCH中包括终端的I-RNTI标识。又比如,paging消息中第1个被指示有下行数据发送的终端标识对应的上行PRACH资源为PRACH-1(即,终端标识与该上行指示信息的发送资源关联,以隐式指示出终端标识)。
请参见图4,图4是本公开实施例提供的一种数据发送方法的流程图,该方法应用于网络设备,如图4所示,该方法包括如下步骤:
步骤401:向终端发送寻呼消息。
步骤402:在所述寻呼消息中包括指示具有终端的下行数据发送的指示信息的情况下,发送所述终端的下行数据。
需说明的是,本实施例中的终端可选为在空闲态(IDLE)或者非激活态(INACTIVE)。上述寻呼消息可为特定寻呼消息,与相关技术中的寻呼消息采用不同的配置信息。上述下行数据可选为数据无线承载(Data Radio Bearer,DRB)数据。
可选的,上述指示具有终端的下行数据发送的指示信息可以是终端的标识信息,比如I-RNTI或ng-5G-S-TMSI,也可以是比如1bit指示信息,当该指示信息为1时,表示有该终端的下行数据发送。
本公开实施例中,可以实现当终端在空闲态或非激活态时,网络设备将相应下行数据直接发送给该终端,从而减少下行数据的发送延时。
