Description

上行传输方法及相关设备 技术领域
本发明涉及无线通信领域,尤其涉及上行传输方法及相关设备。
背景技术
无线通信系统使用的频谱分为授权频谱(英文:licensed spectrum)和非授权频谱(英文:unlicensed spectrum)。对于商用的无线通信系统,运营商需要拍卖授权频谱,用户获得授权后,可以使用相应的频谱开展无线通信的运营活动。非授权频谱不需要拍卖,任何人都可以合法的使用这些频段,比如在2.4GHz和5GHz频带上的无线保真(英文:Wireless-Fidelity,简称:WiFi)设备。通常,授权频谱上的载波称为授权载波,非授权频谱上的载波称为非授权载波。随着无线通信技术的发展,无线通信网络中传输的信息量日益增加,抢占非授权频谱传输信息,可以提高无线通信网络中的数据吞吐量,更好地满足用户的需求。
在长期演进的非授权频谱(英文:Licensed-Assisted Access Using Long Term Evolution,简称:LAA-LTE)系统中,LAA-LTE的节点通过说前先听原则(英文:listen before talk,简称LBT)使用信道资源,其中,LBT是一种载波监听多路访问(英文:Carrier Sense Multiple Access,简称:CSMA)技术。
现有的第三代合作伙伴计划(英文:3rd Generation Partnership Project,简称:3GPP)中关于LAA-LTE的上行传输技术分为两种,一种是演进型基站(英文:evolved Node B,简称:eNB)通过LBT抢占信道,如果抢占到了信道,给用户设备(User Equipment,简称:UE)发送上行链路(英文:Uplink,简称:UL)授权(英文:grant)信息,并且发送一些填充信息来占用信道,直到UE进行上行传输。另一种是当UE接收到UL grant后,通过LBT抢占信道,如果信道空闲,UE抢占到信道,则根据eNB的调度,发送相应数据;若UE没有抢占到信道,则放弃本次传输。
然而,对于UE通过LBT抢占信道的方案,存在如下缺点:
当在下行链路中传输了UL grant时,若UE没有抢占到信道,则不能及时进行上行传输,从而将造成上行传输延时与信今的浪费。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。在下文描述中,处于解释而非限定的目的,阐述了一些特定细节以便清楚理解。在一些实施例中,省略了公知的装置、电路和方法的详细描述,以免因不必要的细节使得描述模糊。通篇描述中,相同的引用数字和相同的名称指代相同或相似的元素。
实施例一、
本发明实施例提供一种上行传输方法,如图1所示,包括:
S101、UE获取所述UE待发送的上行数据的上行传输时长。
具体的,本发明实施例中,UE可以通过系统配置信息或者无线资源控制协议(英文:Radio Resource Control,简称:RRC)获取所述UE待发送的上行数据的上行传输时长,本发明实施例对此不作具体限定。
S102、UE获取基站在非授权载波上传输的下行数据的下行传输时长。
具体的,如背景技术中所述,授权频谱上的载波称为授权载波,非授权频谱上的载波称为非授权载波。
本发明实施例中,一种可能的实现方式中,UE获取基站在非授权载波上传输的下行数据的下行传输时长,具体可以包括:
UE接收基站发送的所述下行传输时长。
其中,该下行传输时长可以为所述基站通过非授权载波上的物理下 行控制信道(英文:Physical Downlink Control Channel,简称:PDCCH)发送给所述UE的。或者,
该下行传输时长可以为所述基站通过授权载波上的PDCCH发送给所述UE的。
本发明实施例对下行传输时长的传输形式不作具体限定。
需要说明的是,通常在授权载波或非授权载波的PDCCH的下行控制信息(英文:Downlink Control Information,简称:DCI)字段中增加新的比特来指示下行传输时长,由于下行传输时长一定小于每次占用非授权载波的最大信道占用时长,而不同的国家和地区所允许的每次占用非授权载波的最大信道占用时长不同,且当采用不同的接入信道方式时,所允许的每次占用非授权载波的最大信道占用时长也不相同,比如在欧洲法规欧洲电信标准化协会(英文:European Telecommunications Standards Institute,简称:ETSI)中规定,当采用基于帧的设备(英文:Frame based equipment简称:FBE)的方式或者基于负载的设备(英文:load based equipment简称:LBE)的操作A(英文:optionA)时,其每次占用非授权载波的最大信道占用时长小于10ms;当采用的是LBE中的操作B(英文:option B)时,其每次占用非授权载波的最大信道占用时长小于13ms;而在日本,相关的法规规定,其每次占用非授权载波的最大信道占用时长要小于4ms。因此,本发明实施例中,针对不同的每次占用非授权载波的最大信道占用时长标准,可以选取新增的比特数小于或等于4。
其中,最大信道占用时长是指单个设备持续占用信道的最大时长。该单个设备具体可以是UE、基站、或者无线保真(英文:WIreless-Fidelity,简称:Wifi)的接入点(英文:Access Point,简称:AP)等,本发明实施例对此不作具体限定。
另一种可能的实现方式中,UE获取基站在非授权载波上传输的下行数据的下行传输时长,具体可以包括:
UE接收基站发送的所述下行数据的结束位置信息;
UE获取所述下行数据的起始位置信息;
UE根据所述起始位置信息和所述结束位置信息,确定所述下行传输 时长。
即,该实现方式中,下行传输时长通过下行数据的结束位置与起始位置计算获得。
其中,该起始位置信息的获取方式有很多,比如:可以通过检测前导(英文:preamble)信号的方法获得起始位置信息或者可以通过后一个子帧中的PDCCH来指示前一个子帧的起始位置信息等等。本发明实施例对该起始位置信息的获取方式不作具体限定。
该结束位置信息可以为所述基站通过非授权载波上的PDCCH发送给所述UE的。或者,
该结束位置信息为所述基站通过授权载波上的PDCCH发送给所述UE的。
本发明实施例对该结束位置信息的传输形式不作具体限定。
需要说明的是,通常在授权载波或非授权载波的PDCCH的DCI字段中增加1比特来指示结束位置,比如,可以设置该比特位为0表示后续没有数据进行传输,该比特位为1表示后续有数据进行传输;当然,也可以设置该比特位为1表示后续没有数据进行传输,该比特位为0表示后续有数据进行传输,本发明实施例对此不做具体限定。
S103、若所述上行传输时长与所述下行传输时长的总和不大于每次占用所述非授权载波的最大信道占用时长,UE在所述下行数据传输结束后在所述非授权载波上发送所述上行数据。
示例性的,如图2所示,为上行传输时长与下行传输时长的总和小于每次占用所述非授权载波的最大信道占用时长时的上行传输方式;如图3所示,为上行传输时长与下行传输时长的总和等于每次占用所述非授权载波的最大信道占用时长时的上行传输方式。可以看出,在上行传输时长与所述下行传输时长的总和不大于每次占用所述非授权载波的最大信道占用时长时,UE在所述下行数据传输结束后在所述非授权载波上上发送所述上行数据。
需要说明的是,本发明实施例中,步骤S101与步骤S102之间没有必然的执行先后顺序,可以先执行步骤S101,再执行步骤S102;也可以 先执行步骤S102,再执行步骤S101;还可以同时执行步骤S101与步骤S102,本发明实施例对此不作具体限定。
基于本发明实施例提供的上行传输方法,由于本发明实施例中在进行上行传输时,不再像现有技术中一样由UE通过LBT抢占信道,如果信道空闲,UE抢占到信道,则根据eNB的调度,发送相应数据;若UE没有抢占到信道,则放弃本次传输。而是由UE直接获取所述UE待发送的上行数据的上行传输时长和基站在非授权载波上传输的下行数据的下行传输时长,在下行传输时长与下行传输时长的总和不大于每次占用所述非授权载波的最大信道占用时长时,UE在下行数据传输结束后在传输该下行数据的非授权载波上上发送上行数据,从而避免了UE通过LBT抢占信道的方案中当在下行链路中传输了UL grant时,若UE没有抢占到信道,则不能及时进行上行传输,从而将造成上行传输延时与信今的浪费的问题,减少了上行传输延时,同时节省了系统资源。
进一步的,如图4所示,本发明实施例中,在UE获取所述UE待发送的上行数据的上行传输时长(步骤S101);以及,UE获取基站在非授权载波上传输的下行数据的下行传输时长(步骤S102)之后,还可以包括:
S104、若所述上行传输时长与所述下行传输时长的总和大于每次占用所述非授权载波的最大信道占用时长,UE在所述下行数据传输结束后在所述非授权载波上上发送所述上行数据中的部分数据,其中,所述部分数据的上行传输时长与所述下行传输时长的总和不大于所述最大信道占用时长。
具体的,所述上行数据中的部分数据为对上行数据进行截短操作所获得的数据,该截短操作具体可以是截取上行数据中的前段部分数据,也可以是截取上行数据中的后段部分数据,还可以是截取上行数据中的任一部分数据,本发明实施例对此不作具体限定。
示例性的,如图5所示,为上行传输时长与下行传输时长的总和大于每次占用所述非授权载波的最大信道占用时长时的上行传输方式。可以看出,在上行传输时长与下行传输时长的总和大于每次占用所述非授权载波的最大信道占用时长时,UE在所述下行数据传输结束后在所述非授权 载波上发送所述上行数据中的部分数据。
需要说明的是,图5所示的上行传输方式中,所述上行数据中的部分数据的上行传输时长与所述下行传输时长的总和等于所述最大信道占用时长,当然,所述上行数据中的部分数据的上行传输时长与所述下行传输时长的总和也可以小于所述最大信道占用时长,本发明实施例对此不作具体限定。
基于本发明实施例提供的上行传输方法,在UE待发送的上行数据的上行传输时长和基站在非授权载波上传输的下行数据的下行传输时长的总和大于每次占用所述非授权载波的最大信道占用时长时,UE在下行数据传输结束后在传输该下行数据的非授权载波上发送上行数据中的部分数据,其中,所述部分数据的上行传输时长与所述下行传输时长的总和不大于所述最大信道占用时长,也就是说,在UE待发送的上行数据的上行传输时长和基站在非授权载波上传输的下行数据的下行传输时长的总和大于每次占用所述非授权载波的最大信道占用时长时,也可以传输上行数据中的部分数据,从而避免了UE通过LBT抢占信道的方案中当在下行链路中传输了UL grant时,若UE没有抢占到信道,则不能及时进行上行传输,从而将造成上行传输延时与信今的浪费的问题,减少了上行传输延时,同时节省了系统资源。
实施例二、
本发明实施例提供一种上行传输方法,如图6所示,包括:
S601、基站占用非授权载波。
具体的,本发明实施例中,基站可以通过LBT方式抢占信道资源,本发明实施例对此不作具体限定。
其中,此处的信道资源具体指代非授权载波。
S602、基站确定在所述非授权载波上传输的下行数据的下行传输时长。
S603、基站向UE发送所述下行传输时长。
其中,基站向UE发送所述下行传输时长具体可以包括:
基站通过非授权载波上的PDCCH向UE发送所述下行传输时长。或者,
基站通过授权载波上的PDCCH向UE发送所述下行传输时长。
本发明实施例对下行传输时长的传输形式不作具体限定。
需要说明的是,通常在授权载波或非授权载波的PDCCH的DCI字段中增加新的比特来指示下行传输时长,由于下行传输时长一定小于每次占用非授权载波的最大信道占用时长,而不同的国家和地区所允许的每次占用非授权载波的最大信道占用时长不同,且当采用不同的接入信道方式时,所允许的每次占用非授权载波的最大信道占用时长也不相同,比如在ETSI中规定,当采用FBE的方式或者LBE的optionA时,其每次占用非授权载波的最大信道占用时长小于10ms;当采用的是LBE中的option B时,其每次占用非授权载波的最大信道占用时长小于13ms;而在日本,相关的法规规定,其每次占用非授权载波的最大信道占用时长要小于4ms。因此,本发明实施例中,针对不同的每次占用非授权载波的最大信道占用时长标准,可以选取新增的比特数小于或等于4。
基于本发明实施例提供的上行传输方法,由于本发明实施例中在进行上行传输时,不再像现有技术中一样由UE通过LBT抢占信道,如果信道空闲,UE抢占到信道,则根据eNB的调度,发送相应数据;若UE没有抢占到信道,则放弃本次传输。而是在基站抢占非授权载波后,向UE发送在所述非授权载波上传输的下行数据的下行传输时长,以使得UE获取该下行传输时长,在该下行传输时长与UE待发送的上行数据的上行传输时长的总和不大于每次占用所述非授权载波的最大信道占用时长时,UE在下行数据传输结束后在传输该下行数据的非授权载波上发送上行数据,从而避免了UE通过LBT抢占信道的方案中当在下行链路中传输了UL grant时,若UE没有抢占到信道,则不能及时进行上行传输,从而将造成上行传输延时与信今的浪费的问题,减少了上行传输延时,同时节省了系统资源。

S701、基站占用非授权载波。

其中,基站根据所述结束位置,向UE发送所述下行数据的结束位置信息,具体可以包括:
基站根据所述结束位置,通过非授权载波上的PDCCH向UE发送所述下行数据的结束位置信息。或者,
基站根据所述结束位置,通过授权载波上的PDCCH向UE发送所述下行数据的结束位置信息。
本发明实施例对该结束位置信息的传输形式不作具体限定。
需要说明的是,通常在授权载波或非授权载波的PDCCH的DCI字段中增加1比特来指示结束位置,比如,可以设置该比特位为0表示后续没有数据进行传输,该比特位为1表示后续有数据进行传输;当然,也可以设置该比特位为1表示后续没有数据进行传输,该比特位为0表示后续有数据进行传输,本发明实施例对此不做具体限定。
基于本发明实施例提供的上行传输方法,由于本发明实施例中在进行上行传输时,不再像现有技术中一样由UE通过LBT抢占信道,如果信道空闲,UE抢占到信道,则根据eNB的调度,发送相应数据;若UE没有抢占到信道,则放弃本次传输。而是在基站抢占非授权载波后,向UE发送在所述非授权载波上传输的下行数据的结束位置信息,以使得UE根据该下行数据的结束位置信息和起始位置信息获取下行传输时长,在下行传输时长与UE待发送的上行数据的上行传输时长的总和不大于每次占用所述非授权载波的最大信道占用时长时,UE在下行数据传输结束后在传输该下行数据的非授权载波上发送上行数据,从而避免了UE通过LBT抢占信道的方案中当在下行链路中传输了UL grant时,若UE没有抢占到信道,则不能及时进行上行传输,从而将造成上行传输延时与信今的浪费的问题,减少了上行传输延时,同时节省了系统资源。
