Description

一种数据发送方法、信息发送方法及装置 技术领域
本申请实施例涉及通信领域,尤其涉及一种数据发送方法、信息发送方法及装置。
背景技术
目前无线通信系统大规模应用部署,可向多个用户提供各种类型的通信,例如,语音、数据、多媒体业务等。
在当前的长期演进(Long Term Evolution,LTE)技术的讨论过程中,对于随机接入过程中的第三条消息即Msg3,可以在Msg3中传输上行用户数据,涉及利用媒体接入控制协议(Medium Access Control,MAC)随机接入响应(Random Access Responses,RAR)。
现有技术中MAC协议数据单元(Protocol Data Units,PDU)包括:MAC头部(header)、0或多个MAC RAR及可选的填充部分。现有技术中,网络可以通过Msg3向终端设备指示最大的传输块大小(Transport block size,TBS),使得终端设备只能使用该最大的TBS来传输上行用户数据,但是,并不是所有的终端设备都需要使用该最大的TBS,若终端设备发送的上行用户数据小于网络配置的最大TBS,则终端设备就需要在传输上行用户数据时增加填充比特,以将发送上行用户数据的传输块扩容至最大TBS,终端设备按照这种方式发送数据时会造成对传输资源的浪费,且没有考虑到网络侧的情况。

终端设备1-6,又称之为用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)、终端等,是一种向用户提供语音和/或数据连通性的设备,或,设置于该设备内的芯片,例如,具有无线连接功允许的手持式设备、车载设备等。目前,一些终端设备的举例为:手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)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。

对于UE使用TBS传输数据来说,现有技术还有一种可能的方案是,网络设备通知最大TBS,UE可以根据该最大TBS选择比该最大TBS小的一个TBS用于传输数据。基站侧在接收该UE发送的数据时,需要对TBS进行盲检侧。但该方案主要是由UE侧根据当前所要发送的数据大小进行选择,UE侧无法根据网络侧的负载等情况选择TBS。也即UE如何根据网络侧的负载等情况选择合适该UE当前数据传输的TBS,既能平衡网络侧的复杂度又能提高UE侧的灵活性,是需要解决的问题。
请参阅图2所示,为本申请实施例提供的网络设备和终端设备之间的一种交互流程示 意图,本申请实施例提供的数据传输方法,主要包括如下步骤。
201、网络设备确定指示信息,指示信息能够用于以下至少两项:用于指示终端设备发送数据的TBS是第一TBS,指示终端设备发送数据的TBS是第二TBS,以及指示终端设备从TBS集合中选择一个TBS作为终端设备发送数据的第三TBS,其中第二TBS和/或第三TBS是TBS集合中的TBS,TBS集合是根据第一TBS确定的集合,且所述指示信息用于所述至少两项中的一种。
本申请实施例中,网络设备可以为终端设备发送的数据配置一种或者多种TBS,或者网络设备可以指示终端设备怎样确定出TBS。例如网络设备配置终端设备根据第一TBS确定出TBS集合,例如第一TBS可以是网络设备配置的最大TBS,该TBS集合可以由小于该第一TBS的多个TBS构成,该TBS集合中包括有第二TBS和/或第三TBS。网络设备可以为终端设备配置第一TBS,或者网络设备可以为终端设备配置第二TBS,或者网络设备可以指示终端设备从TBS集合中确定出第三TBS。举例说明如下:网络设备直接指示UE用集合中的某一个值,比如用现有的MCS/TBS字段指示用集合中的某一个值,该值可以是网络配置的第一TBS或者第二TBS。又如网络设备可以指示终端设备从TBS选择出一个TBS,若终端设备选择的是第三TBS,则网络设备可以通过盲检的方式确定终端设备从TBS集合中选择的TBS是第三TBS。网络设备为了向终端设备指示终端设备如何确定TBS,网络设备可以确定指示信息,指示信息能够用于以下至少两项:用于指示终端设备发送数据的TBS是第一TBS,或指示终端设备发送数据的TBS是第二TBS,以及指示终端设备从TBS集合中选择一个TBS作为终端设备发送数据的第三TBS。
需要说明的是,指示信息用于所述至少两项中的一种,比如网络设备指示了发送数据的TBS是第一TBS,或者指示了发送数据的TBS是第二TBS,或者指示了终端设备从TBS集合中选择一个TBS作为发送数据的TBS,网络设备采用何种方式来确定指示信息所指示的项可以根据网络设备的当前负载来确定。
202、网络设备向终端设备发送指示信息。
在本申请实施例中,网络设备确定出指示信息之后,网络设备可以向终端设备发送指示信息,以使得终端设备可以根据该指示信息确定网络设备配置的TBS。
203、终端设备确定指示信息,指示信息能够用于以下至少两项:用于指示终端设备发送数据的传输块大小TBS是第一TBS,指示终端设备发送数据的TBS是第二TBS,以及指示终端设备从TBS集合中选择一个TBS作为终端设备发送数据的第三TBS,其中第二TBS和/或第三TBS是TBS集合中的TBS,TBS集合是根据第一TBS确定的集合。
204、终端设备根据指示信息确定发送数据的TBS。
在本申请实施例中,终端设备从网络设备接收到指示信息之后,根据该指示信息所指示的至少两项确定网络设备分配给终端设备的是第一TBS、或者第二TBS,或者根据从TBS集合中选择出第三TBS。
205、终端设备根据确定的TBS发送数据。
在本申请实施例中,终端设备通过指示信息确定出网络设备分配给终端设备的TBS之后,终端设备可以使用确定出的TBS向网络设备发送数据,则该数据使用的TBS由网络设备直接指示给终端设备,或者,该数据使用的TBS由终端设备根据网络设备的指示从TBS 集合中确定出来。
206、网络设备根据指示信息确定的TBS接收终端设备发送的数据。
在本申请实施例中,针对不同的指示信息,终端设备需要根据这些指示信息所指示的TBS来发送数据,网络设备同样可以根据指示信息确定的TBS来接收终端设备发送的数据,例如网络设备指示了第一TBS或第二TBS,则网络设备使用第一TBS或者第二TBS来接收数据,或者网络设备指示终端设备从TBS集合中确定出使用的TBS,则网络设备可以对TBS集合的中的TBS进行盲检来确定出终端设备使用了第三TBS。
通过前述实施例的举例说明可知,本申请实施例中网络设备可以确定指示信息,指示信息能够用于以下至少两项:用于指示终端设备发送数据的TBS是第一TBS,或指示终端设备发送数据的TBS是第二TBS,以及指示终端设备从TBS集合中选择一个TBS作为终端设备发送数据的第三TBS。网络设备发送该指示信息给终端设备,从而终端设备可以根据该指示信息确定出发送数据所使用的TBS,实现对发送数据所使用的TBS的指示。

其中,网络设备通过指示信息携带使能比例系数N,使得满足条件的终端设备能够选择TBS集合中的某一个TBS或者选择第二TBS,如果不满足条件可以选择第一TBS。举例说明如下:终端设备被使能的条件:接收到对应CE level下的N值;(RA-RNTI)mod N=0。类似的,终端设备也可以根据临时小区无线网络临时标识和指示信息,或者前导标识和指示信息确定发送数据的TBS是第一TBS、第二TBS或第三TBS。
需要说明的是,上述实施例中主要针对第三TBS的确定,例如如果临时小区无线网络临时标识不满足条件,则终端设备不能从TBS集合中自主选择第三TBS,这种情况下终端设备选择第一TBS或第二TBS。

接下来通过详细的场景例对本申请实施例提供的数据发送方法和数据接收方法进行举例说明。
在本申请的一些实施例中,网络设备通过公共信令或者专用信令对CE level 0/1/2/3中的某一个或者某几个覆盖增强等级的UE使能,使得UE能够选择小于系统消息通知的最大TBS值。
例如通过公共信令或者专用信令是否包含指示信息,来使能UE,即所述公共信令或者专用信令包含指示信息时,使能UE可以选择小于网络配置的最大TBS;如果所述信令不包含指示信息,则UE不能选择小于网络配置的最大的TBS,UE根据网络通知的最大的TBS发送数据。
又如,网络设备通过公共信令或者专用信令根据CE level指示CE level 0/1/2/3中的某一个或者某几个覆盖等级的使能比例系数N,使得满足条件的UE能够选择小于系统消息通知的最大TBS值。
UE被使能的条件:
接收到对应CE level下的N值;
(RA-RNTI)mod N=0。
一种可能的方案是:UE根据该信令是否包含指示信息确定采用哪一种TBS。另一种可能的方案是:该指示信息至少包含2种状态,一种状态指示UE直接根据最大的TBS发送数据,另有一种状态指示UE可以选择比最大的TBS值小的TBS.
通过公共信令或者专用信令使能CE level 0/1/2/3中的某一个或者某几个覆盖增强等级,从而匹配网络负载情况。
在本申请的另一些实施例中,通过公共信令或者专用信令小区级地使能UE可以选择小于网络配置的最大的TBS。
例如:通过公共信令或者专用信令是否包含指示信息或者指示信息指示的状态,来使能当前小区下面的所有UE,即所述公共信令或者专用信令存在时,使能当前小区下面的所有UE可以选择小于网络配置的最大TBS;如果所述信令不存在,则当前小区下面的所有UE不能选择小于网络配置的最大的TBS,UE根据网络通知的最大的TBS发送Msg3。
通过公共信令或者专用信令使能小区下面所有的UE可以选择小于网络配置的最大TBS,具有信令开销小的优点。
在本申请的另一些实施例中,通过网络发送的控制信息使能一组UE可以选择小于网络配置的最大TBS。
例如,公共信令或者专用信令通知参数N,N为取值集合中的某一个值,UE被使能的条件为:
UE1收到公共信令或者专用信令,即N值;
UE1的RA-RNTI满足(RA-RNTI)mod(N)=0。
否则,UE不被使能。例如N的取值集合为{2,3,5,7}或者{2,5,7,9}。
又如,在MAC header中使能,在MAC header中新增一个sub-header,用于指示当前的MAC PDU中包含的UE可以选择小于网络配置的最大TBS。
Mac header中的subheader中包含preamble ID,UE根据定时关系得到接收MAC RAR的时刻,然后从对应时刻上接收的MAC RAR中选择preamble ID和自已相同的MAC RAR。
新增子头中T=0,且为最后一个子头。新增子头中指示N值,N值为取值集合中的某一个值。例如新增子头指示的N值如下表1所示。
比特值 N
00 1
01 2
10 4
11 8
又如,UE被使能的条件为:
该子头出现;
PreambleID满足(PreambleID)mod(N)=0。
网络可以根据负载情况配置N值,从而使能一组UE可以选择小于网络配置的最大TBS。
在本申请的另一些实施例中,通过MAC RAR使能某一个UE。
对于MTC UE,MAC RAR中有预留比特,可以用这个比特使能UE;MCS/TBS可能会释放,可以用该字段占用的比特使能;ModeA的CSI字段可能会释放,可以用该字段占用的比特使能。对于窄带物联网(Narrow Band Internet of Things,NB-IoT)UE,MAC RAR中有保留比特,可以用这个比特使能UE。
网络可以根据负载情况使能某个或者某些UE可以选择小于网络配置的最大TBS。如果负载比较重,就使能少一点的UE选择小于配置的TBS的值。反之,就使能多一些的UE。使能的比例决定了基站的盲检情况。使能的比例越高,基站盲检的复杂度就越高。通过使能比例可配,实现了网络盲检复杂度与网络负载匹配。
