Description

上行传输方法、终端与网络设备 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及一种上行传输方法、终端与网络设备。
背景技术
在现有的长期演进(Long Term Evolution,LTE)系统中,当终端有发送上行数据的需求时,向基站发送调度请求(Scheduling Request,SR);基站接收到SR后,为终端分配上行专用信道资源;终端在基站分配的上行专用信道资源上向基站上报将要传输的上行数据的缓存状态报告(Buffer Status Report,BSR),BSR指示了终端要传输的数据量;基站接收到终端的BSR后,为终端分配上行资源,用以传输上行数据。
但是,基站为终端分配上行资源之前首先必须要知道上行信道质量,而基站需要根据终端上报的探测参考信号(Sounding Reference Signal,SRS)估计上行信道质量。因此,在基站为终端调度上行资源之前,还需要指示终端上报SRS,以便于基站对上行信道质量做出评估,为终端分配较合适的上行信道进行传输上行信号。
上述可知,现有的上行资源调度过程会产生较长的上行时延。
发明内容

本发明实施例的技术方案中涉及终端。终端用还可以称之为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端设备、无线通信设备、用户代理或用户装置。例如,该终端可以是移动电话(或称为“蜂窝”电话)、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络或5G之后的网络中的终端等,本发明实施例对此不作限定。终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,或者可以通过自组织或免授权的方式接入分布式的点对点(Ad-Hoc)模式网络以及用户部署的子网络,终端还可以通过其他方式接入网络进行通信,本发明实施例对此不作限定。
本发明实施例的技术方案中还涉及网络设备。网络设备可以是用于与用户设备进行通信的网络侧设备。具体地,该网络设备可以是为小区内移动或固定的终端提供无线接入、通信服务的网络设备。例如,该网络设备可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB)。或者该网络设备还可以为中继站、接入点、车载设备、可穿戴设备。该网络设备还可以为未来5G网络或5G之后的网络中的网络侧设备、未来演进的PLMN网络中的网络侧设备, 或者NR网络中的网络侧设备等。
如上文所述,现有的上行资源调度过程会产生较大的上行时延。在当前正在讨论的5G系统或NR)系统中,有一些业务可能需要非常短的调度时延,如果采用现有技术实现上行资源的调度,无法满足要求短的上行调度时延的业务的需求。
针对上述技术问题,本发明实施例提出一种上行传输方法、网络设备与终端,可以有效降低上行资源调度过程中的时延。
图1为本发明实施例提供的上行传输方法100的示意性流程图,该上行传输方法100包括:
110,网络设备为终端分配第一时频资源与第二时频资源,该第一时频资源用于传输上行调度请求,该第二时频资源用于传输上行参考信号。
具体地,网络设备预先为终端分配用于传输上行调度请求的第一时频资源与用于传输上行参考信号的第二时频资源。换句话说,基站预先规定了上行调度请求能够占用的时域资源与频域资源,也预先规定了上行参考信号能够占用的时频资源与频域资源。这样的话,终端可以主动在网络设备分配的时频资源上向网络设备发送上行参考信号,应理解,网络设备可以根据终端上报的上行参考信号确定上行信道质量。
具体地,第一时频资源例如为物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)资源。可选地,第一时频资源还可以为其它预先分配的上行传输资源,例如终端竞争接入时所用的上行资源,具体地,例如LTE系统中的随机接入信道(Physical Random Access Channel,RACH)。
具体地,第二时频资源也可以称之为上行参考信号传输资源。
应理解,第二时频资源与第一时频资源不同。
120,终端确定网络设备分配的第一时频资源与第二时频资源。
可选地,作为一种实现方式,终端可以通过接收网络设备下发的信令来获知第一时频资源与第二时频资源。
具体地,例如,网络设备向终端发送无线资源控制(Radio Resource Control,RRC)信令,该RRC信令中携带用于指示第一时频资源与第二时频资源的信息,换句话说,该RRC信令指示了用于传输上行调度请求的时频资源的时域信息与频域信息,该RRC信令还指示了用于传输上行参考信号的时频资源的时域信息与频域信息。终端根据该RRC信令,能够获知用 于传输上行请求调度的第一时频资源与用于传输上行参考信号的第二时频资源。
可选地,作为另一种实现方式,终端可以通过系统预配置信息获知第一时频资源与第二时频资源。
具体地,例如,在网络设备为终端分配第一时频资源与第二时频资源之后,通过通信协议在终端上配置系统预配置信息,该系统预配置信息携带用于指示第一时频资源与第二时频资源的信息,换句话说,该系统预配置信息指示了用于传输上行调度请求的时频资源的时域信息与频域信息,该系统预配置信息还指示了用于传输上行参考信号的时频资源的时域信息与频域信息。终端通过该系统预配置信息,能够获知用于传输上行请求调度的第一时频资源与用于传输上行参考信号的第二时频资源。
130,当终端需要向网络设备发送上行数据时,利用该第一时频资源向该网络设备发送上行调度请求,并利用该第二时频资源向该网络设备发送上行参考信号。
应理解,终端向网络设备发送的上行调度请求(Schedule Request,RS)用于告知网络设备,终端需要上传上行数据。具体地,该上行调度请求可以只携带1Bit的信息。
具体地,例如,第一时频资源为PUCCH资源,终端可以在PUCCH资源上通过上行控制信息(Uplink Control Information,UCI)向网络设备发送上行调度请求。
具体地,终端向网络设备发送的上行参考信号例如为探测参考信号(Sounding Reference Signal,SRS)。网络设备可以根据终端上报的SRS以及网络设备已知的信息估计上行信道质量。应理解,该上行参考信号还可以为其他任意可使得网络设备估计上行信道质量的参考信号。
140,网络设备在接收到终端利用第一时频资源发送的上行调度请求后,获知终端需要上传上行数据,需要为终端分配上行数据;在接收到终端利用第二时频资源发送的上行参考信号后,可以根据该上行参考信号,确定上行信道质量。
在本发明实施例中,当网络设备接收到终端发送的上行调度请求之后,网络设备可以为终端分配上行专用信道资源,例如,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)资源;终端在网络设备分配的 PUSCH资源上向网络设备上报将要传输的上行数据的数据量,例如,终端向网络设备上报缓存状态报告(Buffer Status Report,BSR),BSR能够指示终端将要上报的上行数据的数据量;当网络设备接收到终端发送的上行参考信号(例如SRS)之后,可以根据该上行参考信号确定上行信道质量,然后网络设备可以根据上行信道质量与终端上报的上行数据的数据量,为该终端分配上行资源,以便于终端可以利用该上行资源上报上行数据。
上述可知,在本发明实施例中,终端在需要发送上行数据时,除了可以利用预配置的第一时频资源向网络设备上报上行调度请求之外,还可以利用预配置的第二时频资源主动向网络设备上报上行参考信号,从而使得网络设备在为终端分配上行资源时可以直接基于终端预先上报的上行参考信号估计上行信道质量。相比于现有技术中网络设备在为终端分配上行资源时可能需要临时指示终端上报上行参考信号,本发明实施例提供的上行传输方法能够有效降低上行资源调度过程中的上行时延。
具体地,在步骤130中,终端采用预配置的上行参考信号序列,在第二时频资源上向网络设备发送上行参考信号。
应理解,上行参考信号序列指的是上行参考信号的幅度信息和相位信息,以及该幅度信息与相位信息与承载上行参考信号的时频资源之间的对应关系。
例如,上行参考信号序列可以指示上行参考信号为长度为24的某Z-C序列,且上行参考信号的传输资源位于子帧D的最后一个符号的中间两个物理资源块(Physical Resource Block,PRB)上。再例如,上行参考信号序列可以指示上行参考信号为长度为72的某Z-C序列,且上行参考信号的传输资源位于子帧D的倒数第二个符号的中间六个PRB上。再例如,上行参考信号序列可以指示上行参考信号为长度为144的某Z-C序列,且上行参考信号的传输资源位于子帧D的倒数第三个符号的中间12个PRB上。
具体地,该上行参考信号序列可以是网络设备为终端预先配置的,终端可以通过网络设备下发的信令或通过系统预配置信息,获知该上行参考信号序列。总之,网络设备与终端均知道该上行参考信号序列。
可选地,如图2所示,在一些实施例中,在终端向网络设备发送上行参考信号之前,该上行传输方法100还包括:
150,终端确定需要发送的上行数据的数据量;
160,终端根据预设信息与该上行数据的数据量,从该第二时频资源中确定目标时频资源,该预设信息用于指示数据量范围与该第二时频资源中的子时频资源之间的对应关系,该目标时频资源为该第二时频资源中与目标数据量范围具有对应关系的子时频资源,该目标数据量范围包含该上行数据的数据量的大小。
例如,该预设信息如表1所示:
表1
数据量范围 时频资源
数据量范围1(例如小于或等于A) 子时频资源1
数据量范围2(例如大于A,且小于或等于B) 子时频资源2
数据量范围3(例如大于B,且小于或等于C) 子时频资源3
数据量范围4(例如大于C) 子时频资源4
其中,A、B与C均为正数,且A<B<C。子时频资源1、子时频资源2、子时频资源3与子时频资源4均属于该第二时频资源。在表1的第二行至第行中,每一行的第一列与该行的第二列具有对应关系。
假设在步骤150中,终端判断需要发送的上行数据的数据量在表1所示的数据量范围2内,则确定该数据量范围2为目标数据量范围,与该目标数据量范围具有对应关系的是子时频资源2,则确定该子时频资源2为该目标时频资源。
如图2所示,130终端利用该第二时频资源向该网络设备发送该上行参考信号,具体包括:131利用该目标时频资源,向该网络设备发送该上行参考信号。
具体地,在上述结合表1的例子中,终端利用子时频资源2向网络设备发送上行参考信号。
如图2所示,在网络设备接收到终端发送的上行参考信号之后,该上行传输方法100还包括:
170,网络设备根据该预设信息与该目标时频资源,估计该终端将要发送的上行数据的数据量。
具体地,网络设备接收到终端发送的上行参考信号后,可以获知承载该上行参考信号的时频资源,即该目标时频资源;然后基于该预设信息(例如 表1),确定与该目标时频资源具有对应关系的目标数据量范围;最后,根据该目标量范围,估计终端将要发送的上行数据的数据量。
还以该预设信息如表1所示为例,假设该目标时频资源为表1中所示的子时频资源2,则网络设备根据该预设信息,确定该目标数据量范围为数据量范围2,然后估计终端将要发送的上行数据的数据量在数据量范围2内,例如终端将要发送的上行数据的数据量大于A且小于或等于B。
180,网络设备根据步骤140中确定的上行信道质量与步骤170中估计的终端将要发送的上行数据的数据量,为该终端分配上行资源。
应理解,本发明实施例中的预设信息指示了数据量范围与时频资源之间的对应关系,且数据量范围与时频资源是一一对应的,因此,当网络设备接收到终端利用目标时频资源发送的上行参考信号之后,基于该预设信息与目标时频资源,可以估计得到终端将要发送的上行数据的数据量范围。这种情形下,当网络设备接收到终端在预配置的第一时频资源上发送的上行调度请求、以及终端在预配置的目标时频资源(包含于第二时频资源)上发送的上行参考信号之后,就可以获知以下信息:终端需要传输上行数据、终端将要传输的上行数据的数据量的大小范围与上行参考信号。网络设备基于该上行参考信号可以估计上行信道质量,然后,基于估计的上行信道质量与终端将要传输的上行数据的数据量的大小范围,就可以为终端分配上行资源。换句话说,采用本发明实施例提供到方案,终端在需要发送上行数据时,在基于网络设备预配置的时频资源以及该预设信息,向网络设备上报上行调度请求与上行参考信号之后,就可以获取到网络设备为终端分配的上行资源了,进而利用该上行资源向网络设备发送上行数据,因此,相比于现有的上行资源调度流程,本发明实施例提供的上行传输方法能够有效降低上行资源调度过程中的上行时延。
可选地,本发明实施例中的该预设信息包括数据量范围与上行参考信号配置信息之间的对应关系,该上行参考信号配置信息用于指示上行参考信号的时频资源与序列,不同的数据量范围对应于不同的上行参考信号配置信息,该目标时频资源为与该目标数据量范围具有对应关系的上行参考信号配置信息所指示的时频资源。
具体地,该预设信息如表2所示:
表2
Figure PCTCN2017070186-appb-000001
其中,A、B与C均为正数,且A<B<C。子时频资源1、子时频资源2、子时频资源3与子时频资源4均属于该第二时频资源。在表2的第二行至第行中,每一行的第一列与该行的第二列具有对应关系。
为了简洁,在表2中,采用“配置1”表示上行参考信号配置信息1,采用“序列1”表示上行参考信号序列1,以此类推。
配置1、配置2、配置3与配置4互不相同。例如,子时频资源1、子时频资源2、子时频资源3与子时频资源4为时域、频域上互不重叠的时频资源。序列1、序列2、序列3与序列4也互不相同。例如,序列1可以指示上行参考信号为长度为24的某Z-C序列,且上行参考信号的传输资源位于子帧D的最后一个符号的中间两个PRB上;序列2可以指示上行参考信号为长度为72的某Z-C序列,且上行参考信号的传输资源位于子帧D的倒数第二个符号的中间六个PRB上;序列3可以指示上行参考信号为长度为144的某Z-C序列,且上行参考信号的传输资源位于子帧D的倒数第三个符号的中间12个PRB上;序列4可以指示不同于上述序列1、序列2或序列3的其他任意可行的上行参考信号序列。
假设在步骤150中,终端判断需要发送的上行数据的数据量在表2所示的数据量范围2内,则确定该数据量范围2为目标数据量范围;基于如表2所示的预设信息可知,与该目标数据量范围具有对应关系的上行参考信号配置信息2(如表2中所示的配置2),即子时频资源2与上行参考信号序列2(如表2中所示的序列2),则将该子时频资源2确定为该目标时频资源。具体地,在步骤130中,采用上行参考信号序列2,利用子时频资源2向网络设备发送上行参考信号。
可选地,在本发明实施例中,终端向网络设备上报的上行调度请求中可以携带与目标数据量范围具有对应关系的上行参考信号配置信息。
具体地,终端向网络设备发送的上行调度请求中可以携带终端所选的上行参考信号配置信息。例如,该上行调度请求包括2Bit的信息。
在本发明实施例中,网络设备通过接收到的上行调度请求,即就可以获知终端所选的上行参考信号配置信息,然后基于该预设信息,就可以获知与终端所选的上行参考信号配置信息具有对应关系的数据量范围,从而可以估计终端将要发送的上行数据的数据量,进而以此为终端分配上行资源,从而可以提高为终端分配上行资源的效率,进而减小上行资源调度过程中的上行时延。
应理解,表1与表2仅为示例而非限定,在实际应用中,该预设信息除了可以表格的形式外,还可以是其他任意可行的形式,例如数据库等,本发明实施例对此不作限定。
可选地,在某些实施例中,该预设信息可以是网络设备为终端预先配置的。在本发明实施例中,该上行传输方法100还包括:终端通过接收该网络设备发送的信令或者通过系统预配置信息,获取该预设信息。
具体地,例如,网络设备为终端配置好该预设信息后,向终端发送携带该预设信息的RRC信令。终端接收到该RRC信令后,就能够获知到该预设信息了。
具体的,例如,网络设备为终端配置好该预设信息后,通过通信协议在终端上配置系统预配置信息,该系统预配置信息包括该预设信息。终端通过该系统预配置信息,能够获知该预设信息。
如图3所示,本发明实施例还提供了一种上行传输方法200,该上行传输方法200包括:
210,网络设备为终端分配用于传输上行参考信号的第二时频资源。
220,终端确定网络设备分配的该第二时频资源。
具体地,终端可以通过接收网络设备下发的信令或通过系统预配置信息获知用于传输上行参考信号的第二时频资源。
230,当终端需要向网络设备发送上行数据时,确定该上行数据的数据量。
240,根据预设信息与该上行数据的数据量,从该第二时频资源中确定 目标时频资源,该预设信息用于指示数据量范围与该第二时频资源中的子时频资源之间的对应关系,该目标时频资源为该第二时频资源中与目标数据量范围具有对应关系的子时频资源,该目标数据量范围包含该上行数据的数据量的大小。
具体地,该预设信息如表1所示,具体描述详见上文结合表1的描述,这里不再赘述。
250,利用该目标时频资源,向该网络设备发送上行参考信号。
具体地,网络设备盲检测终端发送的上行参考信号,通过盲检测,网络设备可以接收到终端利用该目标时频资源发送的上行参考信号。
260,网络设备根据盲检测到的该上行参考信号,获知该终端请求调度上行资源,并根据该上行参考信号,确定上行信道质量。
具体地,当终端需要发送上行数据时,根据将要发送的上行数据的数据量的大小以及该预设信息,确定包含将要发送的上行数据的数据量的大小的目标数据量范围;然后确定与该目标数据量具有对应关系的目标时频资源;然后,利用该目标时频资源向网络设备发送上行参考信号。在这种情形下,网络设备可以盲检终端发送的上行参考信号,当检测到终端发送的上行参考信号之后,网络设备可以获知终端设备需要发送上行数据;基于该预设信息以及承载该上行参考信号的时频资源,可以获知终端将要发送的上行数据的数据量大小;可以根据上行参考信号估计上行信道质量,然后基于终端将要发送的上行数据的数据量大小与估计得到的上行信道质量,可以为终端分配上行资源。
上述可知,在本实施例中,终端向网络设备发送的上行参考信号承担了上行调度请求与上行信道探测的双重功能。本发明实施例提供的方案也能够有效降低上行资源调度过程中的上行时延,此外,还可以减少网络设备与基站之间的交互流程,减少信道负担。
可选地,在本发明实施例中,该预设信息包括该数据量范围与上行参考信号配置信息之间的对应关系,该上行参考信号配置信息用于指示上行参考信号的时频资源与序列,不同的数据量范围对应于不同的上行参考信号配置信息,该目标时频资源为与该目标数据量范围具有对应关系的上行参考信号配置信息所指示的时频资源。
具体地,该预设信息如表2所示,相关描述参见上文结合表2的描述, 为了简洁,这里不再赘述。
在本发明实施例中,当终端需要发送上行数据时,根据将要发送的上行数据的数据量的大小以及该预设信息,从而该预设信息中选择一种合适的上行参考信号配置信息;然后利用所选择的上行参考信号配置信息所指示的目标时频资源向网络设备发送对应的上行参考信号。在这种情形下,网络设备可以盲检终端发送的上行参考信号,当检测到终端发送的上行参考信号之后,网络设备可以获知终端设备需要发送上行数据;基于该预设信息以及承载该上行参考信号的时频资源,可以获知终端将要发送的上行数据的数据量大小;可以根据上行参考信号估计上行信道质量,然后基于终端将要发送的上行数据的数据量大小与估计得到的上行信道质量,可以为终端分配上行资源。
