Description

数据处理方法、节点及终端 技术领域
本发明涉及通信领域,具体而言,涉及一种数据处理方法、节点及终端。
背景技术
第五代移动通信技术(5th-Generation,简称为5G)支持灵活的数据收发或动态时分双工(Time Division Duplexing,简称为TDD)已经是共识,但如果每个小区都是按照业务负载动态自适应改变帧结构或者上下行配置,则会带来邻小区之间下行链路对上行链路冲突DL-to-UL interference(又称为基站间冲突eNB-to-eNB interference)或者上行链路对下行链路冲突UL-to-DL interference(又称为用户终端间冲突UE-to-UE interference)的干扰问题,对数据传输性能产生影响。同样,对于全双工的情形下上下行的数据传输也存在同样的问题。
另外,随着物联网的广泛应用及无线终端的持续增多,原有的基于基站调度的终端数据发送方法将面临巨大的挑战。免调度的数据传输方式将作为一种候选的数据传输方法,该接入方式能显著降低信令开销,缩短接入时延,节省终端功耗。但是,通常情形下,免调度接入方式设备都是自己随机选择资源直接进行数据发送,对于正交多址的接入系统,该方式必然会造成资源碰撞,特别是在海量连接的场景下。
因此,降低邻区或上下行数据传输之间的干扰及资源碰撞的问题需要考虑。

存储器104可设置为存储应用软件的软件程序以及模块,如本申请实施例中的数据方法对应的程序指令/模块,处理器102通过运行存储在存储器104内的软件程序以及模块,从而执行各种功能应用以及数据处理,即实现上述的方法。存储器104可包括高速随机存储器,还可包括非易失性存储器,如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中,存储器104可进一步包括相对于处理器102远程设置的存储器,这些远程存储器可以通过网络连接至移动终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106设置为经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端10的通信供应商提供的无线网络。在一个实例中,传输装置106包括一个网络适配器(Network Interface Controller,NIC),其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中,传输装置106可以为射频(Radio Frequency,RF)模块,其设置为通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述移动终端的数据处理方法,图2是根据本申请实施例的数据处理方法的流程图,如图2所示,该流程包括如下步骤:

步骤S204,第一节点获取感知测量的第一感知测量结果;
步骤S206,第一节点根据第一感知测量结果对数据进行处理。
通过上述步骤,由于在节点发送数据之前,对传输数据的信道进行感知测量,使得节点可以根据感知测量结果知晓传输数据的信道的状况,并根据信道状况对数据进行处理。因此,可以解决相关技术中邻区或上下行数据传输之间的干扰及资源碰撞的问题,并且本申请实施例既能用于授权频谱,也能用于共享频谱及非授权频谱,一方面减少了通常情况下免调度接入下终端UE之间的资源碰撞降低了重传带来的时延,另一方面也能降低灵活TDD带来的邻区干扰问题以及全双工下的上下行干扰问题,提高了数据传输的鲁棒性及系统性能。

可选地,预定时长根据服务质量Qos或数据对应的业务等级设置。
例如,可以传输数据的帧结构里面引入一个字段Gap(同上述预定时长)用于指示节点发送数据之前进行感知测量的时长,感知侦听是否有其他节点发送的CTS或占用信号,以减少灵活TDD及全双工带来的干扰及免调度下终端之间的资源碰撞问题。又例如,Qos高的Gap的长度小,Qos低的Gap的长度长。
又例如,Qos高的业务对应的节点先执行感知测量,感知测量成功后,发送占用信号或者直接发送数据。然后其他低优先级的业务就可以感知测量优先级高的节点发送的占用信号例如前导来确定后面数据的功率或者是否能发送。
可选地,预定时长携带在传输数据的帧中,其中,预定时长通过以下方式之一携带在帧中:在帧的子帧的开始或末尾填充预定时长;在帧中发 送下行控制信息区域和该下行控制信息调度的上行业务数据区域之间填充预定时长,或者,在帧中发送下行控制信息区域和该下行控制信息调度的下行业务数据区域之间填充预定时长;在帧所在时隙的开始或末尾填充预定时长,例如,所述时隙包括微时隙Mini-slot。

可选地,第一节点根据感知测量结果对数据进行处理包括:在预定时长内感知测量到传输数据的第一信道的能量大于预定阈值的情况下,第一节点等待重新调度,或者,进行随机回退,或者,第一节点通过第二信道发送数据,其中,第一节点进行随机回退,即,第一节点在检测到第一信道的能量大时,在检测时间后随机选择发送数据的时间。可选地,第一节点还可以通过第二波束发送数据,其中所述第二波束不同于在感知测量到传输数据的第一信道的能量小于预定阈值时第一信道所使用的波束,或者第一节点通过第二调制编码方式发送数据,其中所述第二调制编码方式不同于在感知测量到传输数据的第一信道的能量小于预定阈值时第一信道所使用的制编码方式。
通过上述步骤,使得可以根据感知测量到的传输数据的信道的能量,更直接、更快速的确定处理数据的方式。
可选地,信道的能量即在信道中传输状态的所有数据对应信号的能量。
可选地,第一节点通过发送功率发送数据包括:第一节点通过发送功 率直接发送数据;第一节点通过发送功率先发送一个标识再发送数据,其中,标识用于指示以下至少之一信息:传输数据的第一信道被占用;传输数据的调制编码等级;传输数据的码本或扩频码;传输数据的波束;传输数据的时域图样;传输数据的频域图样;传输数据的时域图样和频域图样。
可选地,标识包括:感知信号或者序列,其中,感知信号包括占用信号,对于非授权载波,感知信号还包括信标beacon信号,确认发送(Clear to Send,简称为CTS)信号,且感知信号或序列携带有对信道的占用信息,所述的序列包括前导或导频序列。
可选地,第一节点通过第二发送功率发送数据包括:在发送上行数据时免调度的情况下,第一节点采用开环功控的方式调整发送功率以获取第二发送功率,通过第二发送功率发送数据,其中,第二发送功率小于第一发送功率;在发送上行数据时调度的情况下,第一节点选择网络侧预分配的两个功控系数中较小的功控系数调整发送功率以获取第二发送功率,通过第二发送功率发送数据,其中,第二发送功率小于第一发送功率;在发送下行数据时,第一节点调整功控系数以获取第二发送功率,通过第二发送功率发送数据,其中,第二发送功率小于第一发送功率。可选地,当第一节点感知到传输数据的信道的能量小于预定阈值的时候,调整选择以较大的功率发送数据
可选地,在预定时长内感知测量到的传输数据的信道的能量大于预定阈值的情况下,还包括:第一节点对第一信道传输的标识进行检测,识别并选择不同的码本或扩频码在第一信道上发送数据;第一节点通知另一个节点对第一信道进行感知测量。
可选地,在预定时长内对传输数据的信道进行感知测量包括以下之一:在预定时长内检测整个系统带宽的能量;在预定时长内仅检测待发送数据的频域位置的能量。
可选地,在免调度的情况下,,在预定时长内对传输数据的第一信道进行感知测量包括:根据对传输数据的第一信道进行感知测量获取第一信 道时频资源:通过时频资源确定以下信息至少之一:前导序列;导频序列;码本;跳频图样;功率;调制与编码策略(Modulation and Coding Scheme,简称为MCS);传输块大小(Transmission Block Size,简称为TBS)。
可选地,在第一节点对传输数据的信道进行感知测量时,第二节点对传输第二节点将发送的数据的信道进行感知测量;第二节点获取感知测量的第二感知测量结果;第二节点根据第二感知测量结果对数据进行处理。通过上述步骤,使得各节点之间的感知测量过程互不干扰,且使得各节点可以根据各自测量结果对各自的数据进行处理。
例如,图3是根据本申请实施例的采用类似请求发送/确认发送(Request to Send/Clear to Send,简称为RTS/CTS)的机制的数据处理方法示意图,如图3所示:
首先,小区1的基站1在子帧开始位置发送下行链路控制消息(Downlink Control information,简称为DCI)触发后面上行数据的发送,在预定的Gap内进行感知检测,当检测到信号能量低于预定阈值的时候发送一个广播信号,例如类似CTS信号,该信号携带后面连续子帧的占用信息。然后调度的UE检测到该信号后就可以进行上行调度数据的发送。
假设调度的上行的业务优先级高于小区2调度的下行业务。则小区2的基站在发送下行数据前在比小区1更长的Gap内进行信号感知,然后在Gap内侦听基站1发送的CTS信号,如果侦听到CTS信号,则后面可以采用预定的功率发送,如果侦听到则需要调整数据的发射功率采用较小的功率发送数据或者不发送下行数据或者触发上行数据的发送。
又例如,如图3所示,小区2的基站在给UE发送完DCI及CTS后,UE根据接收到的CTS信号的信噪比(Signal-Noise Ratio,简称为SNR)上报给基站接收端的干扰等级,然后基站根据干扰等级调整后续下行数据的功率。例如下行的节点,动态测量感知信号,根据瞬时的干扰等级动态调整或确定下行的功控系数。调度为上行的节点,动态测量感知信号,根据瞬时的干扰等级调整或确定上行的功控系数。对于免调度接入的终端, 在发送数据之前,如果感知到信号能量门限小于等于阈值,则进行数据或前导和数据的发送,如果大于阈值,则进行随机回退,等到下一个时刻再进行感知。
可选地,传输数据的帧的结构包括以下之一:预定时长区域,发送下行控制信息区域,上下行转换的预定时长区域,发送上行区域,其中,预定时长区域用于存储预定时长,预定时长用于在第一节点在发送数据之前进行感知测量,预定时长区域位于所述帧的子帧的开始,或,所述帧所在时隙的开始,或,下行控制信息区域与发送上行区域之间,上行区域包括上行控制区域和上行数据区域;预定时长区域,发送下行控制信息区域,上下行转换的第一预定时长区域,发送上行区域,发送下行区域,其中,预定时长区域用于存储预定时长,预定时长用于在第一节点在发送数据之前进行感知测量,预定时长区域位于所述帧的子帧的开始,或,所述帧所在时隙的开始,或,下行控制信息区域与发送上行区域之间,下行区域包括下行控制区域和下行数据区域,在帧中子帧或时隙的末尾存储有用于上下行转换的第二预定时长区域;预定时长区域,发送上行数据区域,其中,预定时长区域用于存储预定时长,预定时长用于在第一节点在发送数据之前进行感知测量,预定时长区域位于帧的子帧或帧所在时隙的开始;预定时长区域,标识序列,发送上行数据区域,其中,预定时长区域用于存储预定时长,预定时长用于在第一节点在发送数据之前进行感知测量,预定时长区域位于帧的子帧或帧所在时隙的开始。
可选地,在预定时长内感知测量到传输数据的信道的能量大于预定阈值的情况下包括;第一节点判断感知测量到传输数据的信道的能量大于预定阈值的次数是否达到预定门限;在判断结果为是的情况下,第一节点调整发送数据的发送功率;在判断结果为否的情况下,第一节点进行随机回退并继续对传输数据的信道进行感知测量。
可选地,在第一节点判断连续感知测量到传输数据的信道的能量大于预定阈值的次数是否达到预定门限之后,还包括:在第一节点判断达到预定门限的次数达到预设次数的情况下,采用调度接入方式传输数据;或者, 在第一节点接收到的非确认信令NACK的数目达到预设值的情况下,采用调度接入方式传输数据。
可选地,在预定时长内对传输数据的信道进行感知测量之前,还包括:第一节点通过与相邻小区的节点交互确定第一预定数目的子帧在第一节点对应的小区和相邻小区均为上行子帧,第二预定数目的子帧在第一节点对应的小区和相邻小区均为下行子帧。通过上述步骤,也可以减少通常情况下免调度接入下终端UE之间的资源碰撞降低了重传带来的时延,以及降低灵活TDD带来的邻区干扰问题以及全双工下的上下行干扰问题,提高了数据传输的鲁棒性及系统性能。
可选地,以下信息至少之一与终端标识ID对应:前导序列,导频序列,码本,跳频图样。
图4是根据本申请实施例的基于感知的数据传输方法的发送端的流程示意图,如图4所示,包括:
首先,节点在数据发送之前先进行感知测量。所述感知测量包括检测整个系统带宽的能量,或者仅检测待发送数据频域位置的能量。
然后,节点根据感知结果进行相应的处理。
当在Gap时间(相当于上述预定时长)内感知测量到的传输数据的信道的能量小于等于预定义的门限,则按照预定的较高功率或采用较大的功控系数进行数据的发送,或者节点先发送一个序列或感知信号再发送数据。所述的序列包括前导或导频序列。
上述感知信号包括占用信号,对于非授权载波还包括类似beacon信号,CTS信号,且所述感知信号或序列携带以下信息:该节点对信道的占用时长或时间信息。
其他节点感知到该节点的序列或感知信号后,在指示的占用时长内就不用再对信道进行感知测量。
当感知到信号的能量门限大于阈值的时候,则做出如下之一动作:动作一:调整功控系数,以较低功率发送数据,动作二:不再发送等待重新 调度或进行随机回退。动作三:在其他载波或其他波束进行数据发送。
下面对数据的发送过程的情形进行说明。图5是根据本申请实施例的基于感知的数据传输方法的优选流程示意图,如图5所示,包括:
小区1的下行业务优先级高,小区2调度低优先级的上行,UE在上行数据发送之前感知到传输数据的载波的能量门限高于预定义门限,则通过其他载波上报给基站,该UE不再在该载波上发送数据,例如,通过1个比特信息指示是否在该载波上发送数据,0代表发送数据,1代表不再发送数据。同时UE做好数据接收的准备,准备接收基站可能会发送的下行数据。
然后基站收到该UE不能发送数据的信息后,基站可以在该载波感知一下,如果测量到信号的功率低于预设的门限,则可以发送下行数据。
或者,数据发送采用如下的情况:
小区2预调度该时刻可能为上行也可能为下行,然后基站和UE都执行感知,由于地理位置不同,基站感知到信道忙,则不能发送下行数据,同时需要做好接收上行的准备,UE可能感知到门限小于阈值,则发送上行数据,如图6所示。这样节点可以根据自己的感知结果进行数据的发送或者接收。
此时,调度的上行和下行的业务的优先级不同,也可以避免上下行同时发送产生碰撞。因此,通过上述方法进一步实现灵活动态上下行数据的发送。
下面对相邻小区通过感知确认数据发送及干扰协调的情形进行说明。图7根据本申请实施例的相邻小区数据发送示意图,如图7所示,在某个子帧或时隙或者迷你时隙,小区1调度为上行数据发送,相邻小区2调度为下行数据发送,如果按照现有技术不进行感知,则就会有干扰,影响数据性能。
而本申请实施例,会有下面的情况:
假设调度的上行业务的优先级高或者Qos高,则相应的Gap的长度短, 小区1的调度的UE先执行感知检测成功,发送一个前导或序列或者直接发送数据,然后小区2的基站感知到前导后,按照不再发送下行数据,或者仍然以小功率发送下行数据。
或者基站如果该时隙其他频域位置有空闲,可以将数据转到空闲的频域位置发送。同时通过发送前导序列来隐含频域位置。即前导序列跟数据的频域位置一一对应。终端检测到该前导序列,就可以知道数据的频域位置,然后到该频域位置进行数据的接收解调。
或者基站通过其他载波发送显示信令通知改变的数据发送的频域位置。
下面对本申请实施例提到的Gap的长度,位置及帧结构进行说明。图8是根据本申请实施例的数据传输子帧结构示意图,如图8所示,
用于感知测量的Gap的长度是固定的,或者是半静态配置的,或者是动态变化的,与业务的优先级或者Qos对应。例如,Qos或业务等级高的Gap的长度小,Qos或者业务等级低的Gap的长度长。
具体长度通过物理层信令动态指示,或者通过高层信令半静态配置,或者预定义不同Qos或业务优先级跟Gap长度的对应关系。或者节点在Gap内进行感知的时间与业务的等级对应。高优先级的业务感知测量的时间较短,低优先级的业务感知测量的时间长。
具体Gap的位置包括以下之一:
子帧的开始;
下行控制信道和调度上行或下行业务数据之间;
Mini-slot的开始或末尾;
时隙或子帧的开始或末尾。
如图8所示,用于感知测量的Gap1可以位于子帧或时隙的开始,然后是下行控制信息,然后是另一个用于上下行转换的Gap2,然后是用于发送上行数据的区域,包括上行控制区域和上行数据区域。如果后面是下 行的时候,子帧或时隙的末尾还有一个用于上下行转换的Gap3。
或者Gap1位于子帧或时隙的开始,然后是下行控制信息,然后是另一个用于上下行转换的Gap2,然后是上行数据,再是上行控制区域。如果后面是下行的时候,子帧或时隙的末尾还有一个用于上下行转换的Gap3。
图9是根据本申请实施例的免调度数据传输子帧结构示意图,下面结合图9对免调度节点进行数据传输的情况进行说明。对于免调度的UE,在发送数据之前,如果感知到能量门限小于阈值,则进行数据发送,如果大于阈值,则以较小的功率发送或者进行回退,等到下一个时刻再进行感知。
进一步的,所述的感知的时频资源与以下至少之一关联对应:前导;导频序列;码本;跳频图样;功率;MCS;TBS。
其中,前导与UE的ID关联,并且还可以用于同步及信道估计。导频序列用也可以用于UE识别,用于信道估计及信道干扰测量。跳频图样为当节点发送数据后如果在预定的定时时间内没有接收到ACK,则后面在预定时长再在相同的频域位置发送数据,或者在资源池里面选择预定的频域位置进行数据的发送。在时频资源或跳频图样是接收端已知的。
数据传输的子帧或时隙结构如图8所示。最前面有个Gap,然后可能会有一个前导序列,然后是发送的数据。或者当连续感知测量到信号的能量超过阈值次数达到门限的时候,节点才自己调整发射功率进行数据的发送,否则进行随机回退继续进行感知。当重传次数达到最大重传次数的时候,采用调度接入。
下面对数据发送的功率的调整或者确定进行说明。当站点在发送数据之前感知测量到信号的能量大于预定义门限的时候,站点可以采用较小的功率仍然发送数据。对于下行,站点可以自己调整发送功率。该功率既能满足一定的覆盖又不会对邻区的干扰太强。
对于上行基于调度的UE在数据发送的时候,基站可以预配置两个功控系数给UE,一个用于感知到信号强的时候自己的功率确定,另一个用 于感知到信号弱的时候自己功率的确定。当感知到信号强的时候采用较小的功率发送数据,当感知到信号弱的时候采用较大的功率发送数据。
通过该方法一方面能减少邻区的干扰,同时也不影响自己数据的发送。
图10是根据本申请实施例的数据传输结构示意图,下面结合图10对节点根据感知结果进行数据发送的过程进行说明。定义用于感知测量的Gap位置为子帧或时隙的开始,感知的主体为基站。基站在发送下行控制信息之前,先对信道进行感知测量,然后基站根据感知结果确定后面调度上行还是下行数据。
如图10所示。小区1的基站先发送下行数据。然后相邻的小区2的基站在调度数据之前先进行感知测量。
当小区2的基站感知到信号的能量门限小于阈值的时候,可以根据上下行业务负载大小选择调度上行业务还是下行业务。例如,如果上行负载高可以调度上行,如果下行业务负载高就调度下行业务。
当小区2的基站感知到干扰大于阈值的时候,调度下行数据或控制上行数据以小功率发送。或者基站仍然根据上下业务负载大小来决定调度上行还是下行,但此时数据的发射功率低于感知到信号的能量小于阈值的时候。然后基站将调度信息发送给终端,或者调度信息之前已经发送给UE,此时仅发送1比特的触发信令来指示上行还是下行数据的发送。
当调度或者触发上行数据发送的时候,由于可能会有隐藏节点问题,需要UE发送上行数据之前在下行控制和上行数据之间的Gap内再执行一次感知,此感知为一个预定义时长,例如25微秒或者9微秒的能量检测。当在该时间内检测到的能量小于阈值的时候按照基站给的功率系数进行数据的发送,当检测到能量大于阈值的时候不发送数据或者以较小功率发送调度的数据。
本实施例提供另外一种方法减小相邻小区之间的干扰问题。相同运营商的两个基站通过X2口协商上下行配置,做干扰协调,避免上下行的干扰。具体的,对于相邻小区,至少部分子帧上下行是对齐的,通过X2口 半静态通知交互部分子帧类型。某些子帧是上行子帧,某些子帧是下行子帧。剩余子帧各小区独立配置,为灵活上下行。然后基站通过RRC消息通知固定子帧配置。其中,所述的部分子帧用于传输比较重要的上下行信息。
例如:两个基站通过协商固定上下行子帧。例如,子帧0和1固定用于下行传输,子帧2固定用于上行传输。或者固定子帧5和6固定用于下行,子帧7固定用于上行。其中,固定上行子帧用于传输信道探测参考信号(Sounding Reference Signal,简称为SRS),物理随机接入信道(Physical Randim Access Channel,简称为PRACH),信道状态信息(Channel Stata Information,简称为CSI)反馈或用户类别标识符(User ClassI dentifier,简称为UCI)传输,或者固定上行子帧用于传输重传的数据。比如子帧2或者子帧7。然后基站基于此信道信息进行上行或下行调度。固定下行子帧用于传输解调参考信号(Demodulation Reference Signal,简称为DRS)。比如子帧0,1或者子帧5,6。灵活子帧用于站点每次根据业务负载大小进行配置。
UE通过无线资源控制(Radio Resource Control,简称为RRC)消息及动态信令知道哪些子帧为上行子帧后就不用再对该子帧进行盲检及测量,然后仅在剩余子帧进行盲检及测量,在一定程度上还可以减少UE的功耗。
通过该方法至少能保证固定的用于上行或下行的时刻相邻小区的干扰比较小,同时能确保重要信息的鲁棒性。
图11是根据本申请实施例的数据传输示意图,下面结合图11对本申请实施例提到的节点进行信道感知测量的具体方法进行说明。节点在Gap内进行感知测量包括以下至少之一:感知侦听其他节点发送的CTS信号,所述CTS信号携带节点的连续发送数据的时间信息。
如图11所示,小区1某个时刻调度UE1进行上行数据的发送。UE1在数据发送之前先进行感知没有检测到其他节点发送的信号或检测到信 号的能量门限低于预定义的阈值,然后就发送CTS信号,然后就发送调度的上行数据。
相邻的小区2基站在该时刻打算发送下行数据,该下行数据的业务优先级低于小区1发送的上行数据,因此该基站感知的时间长,并且感知到了小区1的UE发送的CTS信号,然后就不能进行下行数据的发送。这样避免了对相邻小区高优先级业务数据传输的鲁棒性。
感知其他节点发送的占用信号,所述占用信号包括前导,导频序列,SRS,解调参考信号(Demodulation Reference Signal,简称为DMRS),DRS,其中,DMRS用于上行控制和数据信道的相关解调,DRS用于仅出现波束赋形模式的UE解调。感知检测信道上的能量,将Gap时间内的总能量与预定的阈值进行比较。感知数据接收端发送的CTS信号,并检测该信号的干扰,判断SNR与预定阈值的大小关系。或者直接执行LBT,如果LBT成功,则以预定功率进行数据的发送,如果失败,则不能进行数据的发送。
当传输的数据的业务优先级相同的时候,还可以采用如下的感知测量方法。节点从Gap时间内随机选择一个长度为t的时间进行感知,如果感知到信号的能量小于预定义值就立即进行数据的发送。
需要说明的是,本申请实施例中所述的节点包括基站(Node B)、演进型基站(eNode B)家庭基站(Home Node B)、中继站(Relay Node,RN)、用户设备(User Equipment,UE),接入点,站点等。
