Description

数据传输方法及装置 技术领域
本公开涉及通信领域,例如涉及一种数据传输方法及装置。
背景技术
随着通讯技术的演进,在5G的无线接入(New Radio,NR)非独立运营场景,一个终端(User Equipment,UE)可以同时连接到两个系统的上行载波,一个是长期演进(Long Term Evolution,LTE)载波,一个是NR载波。如果UE能同时发送两个系统的上行信号,就需要两个射频链(Radio Frequency chain,RF chain)。因此,为了减少UE的成本,许多终端设备商建议UE可以只有一个RF chain,并不强制要求所有UE都必须能支持同时进行两个系统的上行信号发送。这样就会导致UE某个时刻仅能发送LTE和NR中一个上行信号。目前,当终端配置或激活多个载波的时候,即载波聚合(Carrier Aggregation,CA)或者双链接(Dual Connectivity,DC)场景下,终端是按照基站的调度进行上行一个或者多个载波的发送的。该情况下不同载波之间的数据发送切换完全取决于基站的调度实现。
但现在是两个系统不同的基站,因此原来的方法不能解决相关问题。
另外,当UE同时链接到两个小区,且这两个小区属于不同的基站的时候,如果两个基站同时调度UE进行两个载波的数据传输,就会出现N次交调的干扰问题。同时,在终端上行覆盖受限的情况下,受最大发射功率限制,终端如果同时发送多个信号,覆盖性能会更差,同时也会存在功率共享的问题。因此,相关技术不能解决多个载波信号同时发送所出现的上述问题。
发明内容
在两个系统不同的基站的情况下,集中功率发送一个信号是一种更简便的方法。
因此,如何确定或者选择多个载波的信号之一进行数据的发送是一个待解决的问题。
本申请实施例提供了一种数据传输方法及装置,以至少解决相关技术中如何确定或者选择多个载波的信号之一进行数据发送的问题。
根据本申请的一个实施例,提供了一种数据传输方法,包括:

根据本申请的又一个实施例,还提供了一种处理器,所述处理器设置为运 行程序,其中,所述程序在所述处理上运行时执行上述任一项所述的方法。

当调度数据传输的控制信息所在的载波信号的子载波间隔跟数据传输载波信号的子载波间隔不同,或者数据传输载波信号的子载波间隔与对应的HARQ-ACK反馈对应载波信号的子载波间隔不同时,按照参考的定时子载波间隔指示时域资源的位置。
在一实施例中,所述时域资源信息包括以下之一:

当终端配置了多个上行载波,所述多个上行载波包括一个LTE载波,一个NR载波的时候,能力受限的终端如何确定或者选择两个系统载波的信号之一进行数据的发送。
在NR跨载波调度的情况下,当调度数据传输的控制信息所在的载波的numerology跟数据传输载波的numerology不同的时候,或者数据传输的载波的numerology跟对应的混合自动重传请求应答消息(Hybird Automatic Repeat reQues Acknowledgement,HARQ-ACK)反馈对应载波的numerology不同的时候,如何指示调度信令和数据传输之间的定时关系以及数据传输和HARQ-ACK反馈之间的定时关系是个问题。本申请实施例的应用于终端侧的数据传输方法,包括:
确定不同系统的载波信号进行数据传输的时域资源信息。
在一实施例中,所述的时域资源信息包括一个最小时隙或者多个最小时隙、一个时隙或者多个时隙、一个或者多个子帧、一个或者多个无线帧、或者一段不固定的时长、或者一个固定的时长。

在一实施例中,终端通过预定义方式或者接收到基站的配置信息确定不同系统的载波信号进行数据传输的时域资源信息。
然后,在相应的时域资源上选择对应的系统载波信号进行该系统载波数据的发送。
在一实施例中,发送的载波数据通过以下至少一种物理信道或信号承载:上行业务信道(Physical Uplink Shared Channel,PUSCH),短的-上行业务信道(Short-Physical Uplink Shared Channel,s-PUSCH),信道探测参考信号(Sounding Reference Signal,SRS),物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH),短的-物理上行链路控制信道(Short-Physical Uplink Control CHannel,s-PUCCH),以及物理随机接入信道(Physical Random Access Channel,PRACH)。
一个LTE信号和一个NR信号同时需要发送的时候,如何处理终端能力受限制仅支持一个载波信号的发送问题。
方式一:不同系统之间按照预定义或者基站之间协调的方式确定每个载波 发送的时分复用的资源。
例如,可以预定义切换的周期,UE在两个载波之间按照预定义的周期进行不同信号的切换发送。
或者5G基站gNB和4G基站eNB之间交互半静态协调每个系统的传输的时域资源。
方式二:预定义或者与基站之间协调每个时域资源上系统载波发送的优先级。
图4是根据本申请实施例的每个时域资源上LTE和NR的优先级的示意图。如图4所示,定义每个时域资源上LTE和NR的优先级,优先级高的系统如果该时域资源上有数据需要发送则直接在该资源上进行数据的发送,当优先级高的没有数据发送的时候,UE也可以在该时域资源发送优先级低的载波数据。
例如,子帧/时隙N预定义LTE优先级高,如果UE该时刻同时调度了LTE和NR的数据,则UE就发送LTE-PUSCH。如果没有调度LTE的数据仅调度了NR的数据,则也可以发送NR的数据,提高了资源的利用率。
在一实施例中,所述时域资源上系统信号发送的优先级通过以下确定:
根据系统的负载大小或者缓存数据的大小确定某个时域资源上系统的优先级特性;
根据系统的时隙(slot)所传输信息确定某个时域资源上系统的优先级特性;
根据系统的主服务小区Pcell与辅服务小区Scell的情况确定某个时域资源上系统的优先级特性。
方式三:当在某个时域资源上两个系统同时需要发送数据的时候,UE自己选择一个系统的信号进行发送,选择的规则根据以下至少之一确定。
规则一:UE根据链路状态做选择。或者根据路损或者无线资源管理RRM测量的结果,或者覆盖大小。
UE先在NR载波测量,基于路损的测量结果。当测量到高频NR载波的参考信号接收功率(Reference Signal Receiving Power,RSRP)高于预定义门限的时候,则选择高频载波发送。当测量到高频NR载波的RSRP低于预定义门限的时候,则选择低频的LTE载波进行上行数据的发送。
规则二:根据负载大小或者缓存数据BSR的大小确定时域资源上所传输的载波信号。
规则三:根据载波上待传输数据的内容确定时域资源上所传输的载波信号。
例如,预定义上行不同信道或者信号的优先级顺序如下,
PRACH>PUCCH with SR>PUCCH/PUSCH with ACK/NACK>PUCCH/PUSCH with CSI>PUSCH without UCI。
规则四:根据发送的业务类型。
当低时延业务类型跟其他业务类型同时需要发送的时候,终端选择低时延业务进行发送。
规则五:根据载波的Pcell,PSCell(primary cell of secondary carrier group,辅载波组的主服务小区)或Scell的载波属性。
或者是上述因素的结合。当两个系统按照某一个规则判断优先级相等的时候,再结合其他的规则来确定最终系统信号的优先级。
方式四:下行控制信息(Downlink Control Information,DCI)里面指示调度的候选的多个时域位置,如果UE这次没有发,该DCI指示调度的数据下次在哪个地方发在DCI里面给出。
方式五:预定义或者基站之间协调时域资源的使用包括以下三种:第一种时域资源、第二种时域资源以及第三种时域资源。
第一种时域资源:LTE系统载波进行数据发送的优先级高或者固定用于LTE系统载波发送的时域资源;
第二种时域资源:NR系统载波进行数据发送的优先级高或者固定用于NR系统载波发送的时域资源;
第三种时域资源:灵活的时域资源。该时域资源上UE自主选择进行数据发送的载波。
图5是根据本申请实施例的某个周期内时域资源信号发送的示意图,如图5所示,预定义或基站协调某个周期内时域资源信号发送,某些时间单元为预定义的LTE载波的数据发送,某些时间单元为预定义的NR载波的数据发送。剩余时间单元为灵活的时间单元,为UE自主选择进行LTE和NR载波的发送。
在一实施例中,上述基站之间半静态的协调信息通过回程线路backhaul信令,例如x2口传输。
然后基站通过高层信令,例如无线资源控制(Radio Resource Control,RRC)信令或者系统消息块(System Information Block,SIB)或者剩余的最小系统信息(Remaining minimum system information,RMSI)通知给终端,然后终端按 照此信息在相应的时域资源上选择所对应的系统载波信号进行上行数据的发送。
当NR载波进行数据发送的时候,调度信令所在的载波跟数据传输载波不统一,即采用跨载波调度的时候,调度定时及反馈定时确定的问题。定义一个参考的定时numerology。该numerology可以为预定义的值,或者半静态配置的值。例如15KHz,或者30KHz,或者预定义为发送下行调度信息载波的numerology,或者是进行数据传输的载波的numerology,或者是指定载波的numerology。
然后指示的定时按照该参考的numerology或载波进行指示,其他载波按照预定义的尺度关系进行换算。
通过本申请实施例,解决了能力受限的终端在某个时域资源上如何确定或者选择两个系统载波的信号之一进行数据的发送问题,避免了两者同时发送导致均出错带来的系统性能差,同时确保了数据传输的时延,保证了系统的性能。
下面通过具体的应用实施例对一些过程的细节进行详细的说明。
在一个可选的实施例中,对UE同时连接到LTE载波和NR载波的情况下,如何确定哪个载波的数据发送进行说明。
该情况下,LTE数据可以和NR的数据采用时分多路复用(Time Division Multiplexing,TDM)的方式进行发送。具体TDM的图样根据以下之一进行确定:
方式一:预定义的方式。
预定义又包括预定义切换的周期以及TDM的图样。
例如,可以预定义载波或系统数据发送的切换周期。预定义的切换周期可以为2ms或者4ms等,UE在两个载波之间按照预定义的周期进行切换。
或者预定义某些资源给NR用,预定义某些时刻给LTE用。或者说预定义TDM的图样。
方式二:两个系统的基站之间可以进行半静态资源协调的方式。
gNB和eNB之间交互半静态的协调传输的时域资源可以通过backhaul信令,例如X2口。
然后基站通过RRC信令或者RMSI通知给下属的UE,UE按照此信息确定时刻k应该发送LTE信号还是发送NR的上行信号。
如基站通过信令10011100110通知LTE和NR的时分复用的时域资源图样为“LTE NR NR LTE LTE LTE NR NR LTE LTE NR”。
在一实施例中,所述上行信号包括LTE和NR的一些上行信道及信号。如 上行调度的PUSCH,非周期SRS及非周期及周期UCI传输,其中UCI包括调度请求,信道状态信息(Channel State Information,CSI)反馈,预编码矩阵指示(Precoding Matrix Indicator,PMI),秩指示(Rank Indication,RI)反馈,以及跟波束beam相关的一些信息。还有随机接入前导码preamble。
该方式下,基站基于本系统数据所能发送的时域资源进行数据的调度,不会将数据调度到其他系统所能使用的时域资源上,因此不会有调度信令的额外浪费。
在另一个可选的实施例中,对UE同时连接到LTE载波和NR载波的情况下,如何确定哪个载波的数据发送的另外一种方法进行说明。
如预定义或者基站之间协调每个时域资源上信号发送的优先级的方法如下。
定义每个时刻LTE和NR的优先级。如果某个时刻UE同时有LTE信息和NR信息需要发送,则UE按照预定义信息发送的优先级进行载波数据的发送,优先级高的发。
在一实施例中,所述某个时域资源上系统信号发送的优先级通过以下至少之一确定:
根据系统的负载大小或者缓存数据的大小确定某个时域资源上系统的优先级特性。
可以根据之前的统计的每个系统的负载大小信息或缓存大小信息来确定某个时域资源上系统进行数据发送的优先级。负载大的系统在最近的时域资源上的优先级高。
根据系统的slot所传输信息确定某个时域资源上系统的优先级特性。
如预定义上行各个信道的优先级如下:
PUCCH with SR>PUCCH/PUSCH with ACK/NACK>PUCCH/PUSCH with CSI>PUSCH without UCI。
对应相同优先级的UCI和PUSCH中的至少一个,优先级为PUCCH≥PUSCH with UCI>PUSCH without PUSCH。
同时定义不同UCI类型优先级:ACK>SR(下一个时刻出发)>非周期CSI>周期CSI>PUSCH without UCI。
PRACH优先级高于其他所有上行链路(uplink,UL)类型。
根据系统载波的Pcell与Scell的情况确定某个时域资源上系统的优先级特性。
原则PCell数据传输的优先级高于SCell。
例如,当LTE载波被配置为PCell,NR载波被配置为SCell的时候,LTE载波的优先级高于SCell。
或者,上述因素可以结合起来一起确定某个时域资源的信号发送的优先级。
在一实施例中,当本系统的该UE上行负载比较小的时候,基站在优先级高的时域资源上调度上行数据。如LTE基站只在LTE系统载波优先级高的时域资源上调度该UE的上行数据。
当该系统的UE上行负载比较大的时候,基站也可以利用优先级低的时域资源进行上行数据的调度。
通过划分不同系统在某个时域资源发送的优先级的方式提高了数据发送的灵活性以及降低了重要信息进行发送的时延。
在另一个实施例中,针对UE同时连接到LTE载波和NR载波且两个载波同时有数据进行发送的情况下,如何确定哪个载波的数据发送的另外一种方法进行说明。
当UE同时接收到两个下行控制信息DCI,该下行控制信息分别调度某两个上行信号同时在两个载波进行发送,例如PUSCH或者非周期SRS或者非周期上行控制信息的反馈。则UE可以自己选择一个载波进行数据发送,选择的规则包括以下至少之一:
规则一:UE根据链路状态做选择。或者根据两个载波的路损大小或者无线资源管理RRM测量,或者两个载波的覆盖大小。
例如:UE先在NR载波测量,基于路损的测量结果。当测量到高频NR载波的RSRP高于预定义门限的时候,则选择高频载波发送。当测量到高频NR载波的RSRP低于预定义门限的时候,则选择低频的LTE载波进行上行数据的发送。
规则二:根据UE每一个系统下BSR的大小。
例如:某个时刻,UE接收到调度PUSCH信令后,UE判断自己的LTE和NR系统上行数据的BSR大小。当UE的LTE的BSR大于NR的BSR,则UE就发送LTE载波的调度数据。反之,当UE的LTE的BSR小于NR的BSR,则UE就发送NR载波的调度数据。
规则三:根据不同系统待发送的数据的信息内容或信道信号。
如预定义上行各个信道的优先级如下:
PRACH>PUCCH with SR>PUCCH/PUSCH with ACK/NACK>PUCCH/PUSCH with CSI>PUSCH without UCI。
规则四:根据发送的业务类型。
低时延的业务类型的优先级高于其他业务类型。当低时延业务类型跟其他业务类型同时需要发送的时候,终端选择低时延业务进行发送。
规则五:根据载波属性确定。
例如,优先级顺序可以根据PCell>PScell>SCell的顺序进行。特别是当两个载波发送的信道或信号相同的时候,可以按照该顺序确定进行数据发送的载波。
另外,上述的规则可以结合起来使用。UE综合各种因素确定进行LTE载波还是NR载波进行数据的发送。
该方式下基站如果在调度的时域资源上没有接收到该UE的上行数据,则基站可以发送一个下次进行数据传输的时域资源的位置指示信息,该时域位置为该系统载波发送优先级高的时域位置,确保下次传输能够传输正确,同时降低了信令的开销。
在另一个可选的实施例中,针对UE同时连接到LTE载波和NR载波的情况下,数据发送的方法进行说明。
为了减少调度数据发送的时延。数据调度的时候可以采用如下的方式:
NR的下行控制调度信息里面指示调度的上行数据或者信号的传输的候选的多个时域位置,如N,N+2,以及N+4这三个时域位置。如果UE在N时刻只能发送LTE的载波上的数据,而调度的NR的载波数据这次没有能够发送,则该UE可以按照DCI指示的后续的可传输的时域位置信息,将调度的数据下次在N+2时刻进行数据的发送。如果N+2时刻仍然发送LTE的载波数据,则在N+4时刻进行NR载波的发送。如果还是没能发送,则只能将调度的数据丢弃。在一实施例中,上述的N,N+2,以及N+4时域资源可以为以下之一:NR优先级高的时域资源;NR优先级低的时域资源;以及灵活的时域资源位置。
在另一个实施例中,对UE如何确定某个时刻进行哪个载波的数据发送的方法进行说明。
预定义或者基站之间协调某个配置周期内某些时间单元上的数据载波的优先级,然后剩余的时间单元是灵活的,UE可以自己选择进行某个载波的发送。
定义某些时间单元为预定义的LTE载波的数据发送,某些时间单元为预定义的NR载波的数据发送。剩余时间单元为灵活的时间单元,为UE自主选择进 行LTE和NR载波的发送。
预定义的发送周期为基站协调的,为0.125ms,0.25ms,0.5ms,1ms,5ms或者10ms。
然后基站gNB和eNB之间通过backhaul信令协调每个周期内每个时域资源的属性,所述的时域资源属性包括以下三种:
第一种时域资源:LTE系统载波进行数据发送的优先级高或者固定用于LTE载波的发送;
第二种时域资源:NR系统载波进行数据发送的优先级高或者固定用于NR载波的发送;
第三种时域资源:灵活的时域资源。该时域资源上UE自主选择进行数据发送的载波。
其中,所述的时域资源包括一个最小时隙或者多个最小时隙、一个时隙或者多个时隙、一个或者多个子帧、一个或者多个无线帧、或者一段不固定的时长、或者一个固定的时长。
所述时域资源载波优先级的确定规则按照上述实施例2中的一些原则确定。灵活的时域资源上UE自主选择的原则按照实施例3中提到的所述规则进行。
其中,固定用于某个系统载波发送时域资源发送一些可靠性要求高的信息。如PUCCH或者承载上行控制信息的PUSCH,或者PRACH。
通过该时域资源上不同系统载波信号发送的确定方法,可以提高数据发送的灵活性,降低了数据发送的时延,确保了LTE和NR两个系统的性能。
在另一个可选的实施例中,对不同numerology情况下,跨载波调度场景下,调度及反馈定时的指示的确定方法进行说明。
定义一个参考的定时numerology。该numerology可以为预定义的值,例如15KHz,或者30KHz,或者预定义为发送下行调度信息载波的numerology,或者是进行数据传输的载波的numerology,或者是指定载波的numerology。然后其他numerology按照相应尺度进行换算。
该参考的定时numerology还可以为半静态配置的,然后通过RRC消息或者SIB或者剩余的系统消息RMSI通知给终端。
例如,预定义或者半静态配置的参考的定时numerology为15kHz,然后基站在时刻n发送下行控制信息调度PUSCH/PDSCH,且调度的数据传输所在的载波的numerology为30kHz,且控制信息里面指示的控制信息和PUSCH/PDSCH 定时关系为8,则实际PUSCH/PDSCH传输所在的slot或者起始slot应该是n+4个slot的位置。
该定时指示的确定方法也应用于数据传输和对应的HARQ-ACK反馈所在载波的之间的numerology不同的时候的定时关系的确定。
其中,上述的不同numerology对应不同的子载波间隔和不同的时域长度。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端设备(可以是手机,计算机,服务器,或者网络设备等)执行本申请各个实施例所述的方法。
