Description

数据传输方法、终端设备和网络设备 技术领域
本申请实施例涉及通信技术,尤其涉及一种数据传输方法、终端设备和网络设备。
背景技术
授权辅助接入的长期演进(licensed-assisted access using long term evolution,LAA-LTE)通信系统通过载波聚合(carrier aggregation,CA)技术,可以将可用的频谱扩展到5GHz非授权频段。通过授权频谱的辅助,终端设备和网络设备可以在非授权频谱上传输下行传输和上行传输。
为了与其他系统(例如不同运营商的通信系统、Wi-Fi网络等)可以共同使用非授权频段,LAA-LTE通信系统中的终端设备在使用非授权频段发送上行传输时,采用先听后发(listen-before-talk,LBT)的信道接入机制。即终端设备在发送上行传输之前,先对信道进行信道侦听。当通过侦听确定信道空闲时(即信道侦听成功时),终端设备可以在该信道上发送上行传输。终端设备在信道侦听成功后,可以连续发送上行传输的最大时间长度称为最大信道占用时间(maximum channel occupancy time,MCOT)。
现有技术中,终端设备在执行信道侦听后,若终端设备在非授权频段的信道上传输的上行传输无法占满该信道侦听对应的MCOT,则会导致该MCOT的资源利用率较低、信道利用率较低。

具体实施方式
图1为本申请实施例所涉及的一种通信系统的框架图。如图1所示,该通信系统包括:网络设备01和终端设备02。其中,
网络设备01:可以是前述基站,或者各种无线接入点,或者可以是指接入网中在空中接口上通过一个或多个扇区与终端设备进行通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如,基站可以是全球移动通讯(global system of mobile communication,GSM)或码分多址(code division multiple access,CDMA)中的基站(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)中的基站(nodeB,NB),还可以是长期演进(long term evolution,LTE)中的演进型基站(evolutional node B,eNB或eNodeB),或者中继站或接入点,或者未来5G网络中的基站gNB等,在此并不限定。
终端设备02:可以是无线终端也可以是有线终端,无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线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,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。无线终端也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、 用户代理(user agent)、用户设备(user device or user equipment),具有网络接入功能的传感器,在此不作限定。
需要说明的是,上述通信系统可以是LTE通信系统,也可以是未来其他通信系统,例如5G通信系统等,在此不作限制。在本申请实施例中,上述通信系统可以工作在授权频谱,也可以工作在非授权频谱。即,网络设备在授权频谱或非授权频谱上发送下行信息,终端设备在授权频谱或非授权频谱上发送上行信息。
LAA-LTE通信系统通过CA技术,可以将可用的频谱扩展到5GHz非授权频段。通过授权频谱的辅助,终端设备和网络设备可以在非授权频谱上传输下行传输和上行传输。
为了与其他系统(例如不同运营商的通信系统、Wi-Fi网络等)可以共同使用非授权频段,LAA-LTE通信系统中的终端设备在使用非授权频段发送上行传输时,采用LBT的信道接入机制。即终端设备在发送上行传输之前,先对信道进行信道侦听。当通过侦听确定信道空闲时(即信道侦听成功时),终端设备可以在该信道上发送上行传输。当通过侦听确定信道忙碌时(即信道侦听失败时),终端设备放弃在该信道上发送上行传输。需要说明的是,终端设备在信道侦听成功后,可以连续发送上行传输的最大时间长度称为最大信道占用时间(maximum channel occupancy time,MCOT)。也就是说,终端设备在持续占用信道达到该MCOT的长度后,需要释放信道。若终端设备需要继续发送上行传输,则终端设备重新执行LBT才能接入信道。其中,上述所说的上行传输也可以称为上行突发传输(transmission)、上行突发(burst)等。
目前,存在如下两类信道侦听:
第一类信道侦听为长侦听类型的信道侦听,即终端设备在执行第一类信道侦听时,从开始进行信道侦听至信道侦听成功耗时较长。在一些实施例中,第一类信道侦听也可以称为type 1channel access。目前,常见的第一类信道侦听有基于随机回退的空闲信道评测(clear channel assessment,CCA)。
终端设备执行基于随机回退的CCA的流程可以为:终端设备可以在0~初始竞争窗口(contention window size,CWS)之间均匀随机生成一个回退计数器N,并以侦听时隙(例如时长为9us)为粒度对载波进行信道侦听。其中,上述初始竞争窗口的大小具体可以根据网络设备的配置确定。
若终端设备在侦听时隙内检测到信道空闲,则将回退计数器减1。若终端设备在侦听时隙内检测到信道忙碌,则将回退计数器挂起,暂不减1。即,回退计数器的取值在信道忙碌时间内保持不变,直至检测到信道空闲时,才重新对回退计数器进行倒数。具体实现时,终端设备可以将侦听时隙内接收到的信道上的功率与能量检测门限(CCA-energy detection,CCA-ED)进行比较。若信道上的功率高于或等于CCA-ED,则确定信道忙碌,若信道上的功率低于CCA-ED,则确定信道空闲。
当回退计数器归零时,终端设备可以确定信道侦听成功(也可以称为LBT侦听成功)。在该场景下,终端设备可以立即占用该信道发送上行传输。在一些实施例中,终端设备也可以在回退计数器归零后,自行等待一段时间。在等待结束后,终端设备可以再使用一个额外的时隙(例如9us或者25us+9*kus,其中k为零或正整数)对信道进行一次侦听。若终端设备在该额外的时隙内侦听到信道空闲,则终端设备可以确定信道侦听成功。在该场景下,终端设备可以立即占用该信道发送上行传输。
若终端设备在想要占用的时域资源之前未完成回退计数器归零,或者,在想要占用的时域资源之前完成回退计数器归零、但在该额外的侦听时隙侦听到信道忙碌,则终端设备可以确定信道侦听失败(也可以称为LBT侦听失败),此时,终端设备放弃在信道上发送上行传输。
需要说明的是,终端设备在执行基于随机回退的CCA时,基于随机回退的CCA对应的MCOT可以根据待发送的上行传输的接入优先级(priority class)确定。相应地,不同长度的MCOT对应的基于随机回退的CCA的初始竞争窗口的取值也不同。例如,接入优先级可以包括4种,每一种接入优先级对应一套信道侦听参数。其中,信道侦听参数包括竞争窗口集合、最大信道占用时间等。示例性的,接入优先级1的CWS集合为{3,7}、最大信道占用时间为2ms,接入优先级2的CWS集合为{7,15}、最大信道占用时间为4ms,接入优先级3的CWS集合为{15,31,63,127,255,511,1023}、最大信道占用时间为6ms或10ms,接入优先级4的CWS集合为{15,31,63,127,255,511,1023}、最大信道占用时间为6ms或10ms。
第二类信道侦听为短侦听类型的信道侦听,即,终端设备在执行第二类信道侦听时,从开始进行信道侦听至信道侦听成功耗时较短。在一些实施例中,第二类信道侦听也可以称为type 2channel access。目前,常见的第二类信道侦听有单时隙CCA。在一些实施例中,单时隙CCA也称为单次(one shot)CCA或25us CCA。
终端设备执行单时隙CCA的流程可以为:终端设备对信道执行一个长度为预设时间长度(例如25us)的单时隙的侦听。若终端设备在该单时隙内检测到信道空闲,则终端设备确定信道侦听成功。在该场景下,终端设备可以立即占用该信道发送上行传输。若终端设备在该单时隙内检测到信道忙碌,则终端设备确定信道侦听失败。在该场景下,终端设备放弃在信道上发送上行传输。具体实现时,终端设备可以将该单时隙内接收到的信道上的功率与CCA-ED进行比较。若信道上的功率高于或等于CCA-ED,则确定信道忙碌,若信道上的功率低于CCA-ED,则确定信道空闲。
可以理解,第二类信道侦听还可以是其他能够快速对载波进行侦听的信道侦听,这里不做限制。另外,第二类信道侦听的侦听时长也不限于25us,也可以是更多或者更少的时长,第二类信道侦听的次数也不限于为1次,也可以是2次、3次或者更多,此处不作具体限定。
现有技术中,终端设备在发送任一上行传输之前,可以执行第一类信道侦听,并在信道侦听成功后,可以接入信道发送该上行传输。此时,若该上行传输无法占满该第一类信道侦听对应的MCOT,则会导致该MCOT的资源利用率较低、信道利用率较低。
考虑到上述问题,本申请实施例提供了一种数据传输方法,使得终端设可以继续使用该未被占满的MCOT发送其他上行传输,可以提高MCOT的资源利用率和信道的利用率。下面通过一些实施例对本申请的技术方案进行详细说明。下面这几个实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请实施例提供的一种数据传输方法的信令流程图。在本实施例中,终端设备可以在使用主集天线接收服务小区的数据或发送服务小区的数据的同时,使用分集天线对异频小区进行测量。如图2所示,该方法可以包括:
S101、网络设备向终端设备发送指示信息。
其中,该指示信息用于指示终端设备发送第一上行传输所使用的第一时域资源。本申请实施例对于指示信息的其它特征不做限定。本领域技术人员可以理解的是,该指示信息在5G移动通信系统可能仍然沿用上行授权(uplink grant,UL grant)的术语,也可能采用其他的术语。因此,本申请实施例对指示信息在各个通信系统中的命名不作限定。可选的,上述网络设备可以通过下行控制信令发送该指示信息,也可以通过其他信令发送该指示信息。
S102、终端设备接收该指示信息。
S103、终端设备在第一时域资源上向网络设备发送第一上行传输,在第二时域资源上向网络设备发送第二上行传输。
其中,第二时域资源为终端设备根据第一时域资源确定的时域资源,第一时域资源和第二时域资源在时间上连续或不连续。
S104、网络设备在第一时域资源上接收第一上行传输,在第二时域资源上接收第二上行传输。
上述第一上行传输可以为网络设备调度终端设备发送的上行传输。即终端设备在接收到网络设备发送的UL grant后,在UL grant所指示的第一时域资源上发送的上行传输。在一些实施例中,第一上行传输也可以称为基于调度的上行(scheduled uplink,SUL)突发、SUL传输。需要说明的是,上述终端设备在需要发送第一上行传输之前,需要先向网络设备发送调度请求(scheduling request,SR),以请求网络设备为终端设备分配资源。进一步的,上述第一上行传输还对应第一频域资源,例如,该第一频域资源包括至少一个物理资源块(physical resource block,PRB)。可选的,第一频域资源可以为该网络设备通过该指示信息指示给该终端设备的,还可以为网络设备通过其他的指示信息指示给终端设备等,对此不进行限定。
上述第二上行传输可以为终端设备以免调度方式发送的上行传输,即,终端设备自主的在网络设备半静态配置的时域资源上发送的上行传输。也就是说,发送第二上行传输所使用的第二时域资源并不是网络设备通过UL grant动态调度的。因此,上述终端设备在需要发送第二上行传输之前,不需要再向网络设备发送SR,也不需要再等待网络设备发送UL grant。因此,可以提高数据传输效率,以及,信道使用效率。在一些实施例中,第二上行传输也可以称为免调度许可上行(grant free uplink or grant less uplink,GUL)传输、GUL突发、自主上行(autonomous uplink,AUL)传输、AUL突发。进一步的,上述第二上行传输还对应第二频域资源,例如,该第二频域资源包括至少一个物理资源块。可选的,第二频域资源为该网络设备通过高层信令配置的,和/或通过其他指示信息,例如物理层控制信令配置给该终端设备的,对此不进行限定。
其中,上述第二上行传输(即以免调度方式发送的上行传输)可以包含以下特征中的至少一种:
1、终端设备发送该上行传输之前,不需要向网络设备发送SR,也不需要基于网络设备的动态调度发送该上行传输,而是由终端设备自主决定发送。
2、区别于第一上行传输(即基于网络设备调度终端设备发送的上行传输),用于发送第二上行传输的GUL时域资源和/或GUL频域资源,由网络设备半静态配置给终端设备。。其中,GUL时域资源也称之为用于免调度方式传输的时域资源。也就是说,该第二上行传 输并不是网络设备通过UL grant动态调度给该终端设备的。可选的,GUL时域资源和GUL频域资源可以由网络设备通过高层信令(例如RRC信令)和/或物理层控制信令配置给终端设备。也就是是说,GUL时域资源是周期性的,或者说,GUL时域资源是持续性的时域资源。在本申请实施例中,上述第二时域资源可以为网络设备半静态的配置的用于免调度方式传输的时域资源的一部分。需要说明的是,上述所说的物理层控制信令可以由第一用户特定无线网络临时标识(radio network temporary identifier,RNTI)加扰,例如,由GUL小区无线网络临时标识(GUL cell radio network temporary identifier,GUL C-RNTI)、或AUL C-RNTI,或半持续调度C-RNTI(semi-persistent scheduling C-RNTI,SPS C-RNTI)加扰。调度第一上行传输的UL grant由第二用户特定RNTI加扰,第二用户特定RNTI与第一用户特定RNTI不同,例如,第二用户特定RNTI为C-RNTI。
3、终端设备在发送第二上行传输之前,可以向网络设备上报免调度许可上行控制信息(grantless uplink control information,G-UCI)。该G-UCI为该第二上行传输对应的控制信息。该G-UCI可以包括与该第二上行传输中包括的至少一个数据包对应的混合自动重传请求(hybrid automatic repeat request,HARQ)进程的HARQ进程号信息、新数据指示(newdata indicator,NDI)信息、与该第二上行传输包括的至少一个数据包对应的冗余版本(redundancy version,RV)信息以及该终端设备的用户标识(记为UE ID)信息中的至少一种信息。
可以理解,第一时域资源为第一上行传输所对应的时域资源。也就是说,终端设备占用第一时域资源发送第一上行传输。
可以理解,第二时域资源为第二上行传输所对应的时域资源。也就是说,终端设备占用第二时域资源发送第二上行传输。
可以理解,发送第一上行传输的第一时域资源或发送第二上行传输的第二时域资源可以包括至少一个用于传输上行信息的时间单元。例如,上述时间单元可以为传输时间间隔(transmission time interval,TTI)。其中,该TTI可以是1ms TTI,也可以是短于1ms的短传输时间间隔(short transmission time interval,sTTI)。即,sTTI所占用的时域资源长度短于1ms TTI。也就是说,当某个数据信道对应sTTI时,该数据信道占用的时域资源长度短于1ms。sTTI可能支持的可选长度包括7个时域符号、1个时域符号、2个时域符号、3个时域符号或4个时域符号等结构。其中,这里所说的时域符号可以是单载波频分多址接入符号(single carrier frequency division multiplexing access symbol,SS),也可以是正交频分多址接入符号(orthogonal frequency division multiplexing access symbol,OS)等。sTTI还可以支持其他短于1ms的TTI长度,不再一一赘述。在一些实施例中,上述1ms的TTI也可以称为长度为1ms的子帧,上述短于1ms的sTTI也可以称为迷你时隙(mini-slot)。
在第一时域资源或第二时域资源包括多个时间单元时,该多个时间单元在时间上可以是连续的。这里所说的连续可以是指信道占用是连续的,即该终端设备持续地占用该多个时间单元发送信息,也可以是指时间单元的(例如,TTI或子帧)序号连续。也就是说,时间上连续的多个时间单元中,任意两个相邻的时间单元之间可以没有空隙,也可以有空隙。例如,终端设备可以不占用前一时间单元结尾位置的时域资源发送上行传输,将该时域资源保留为空闲,或者,终端设备不占用后一时间单元起始位置的时域资源发送上行传输,将该时域资源保留为空闲等,本申请实施例对此不进行限定。即,该多个时间单元中 的任意一个时间单元可以是一个完整的时间单元,也可以是一个时间单元的一部分。
可选的,在第一时域资源包括多个时间单元时,发送第一上行传输的第一时域资源可以由一个UL grant所调度,也可以由至少两个UL grant调度。即,该至少两个UL grant的每个UL grant调度用于发送第一上行传输的至少一个时间单元。示例性的,发送第一上行传输的第一时域资源包括4个在时间上连续的时间单元#1至#4,分别由第一UL grant和第二UL grant调度,以两个UL grant分别调度两个时间单元为例,则上述第一UL grant可以调度时间单元#1、#2,第二UL grant可以调度时间单元#3、#4。
在本实施例中,上述终端设备在发送第一上行传输之前,可以对信道执行第三信道侦听。该第三信道侦听例如可以为前述所说的第一类信道侦听。其中,终端设备在发送上述第一上行传输之前所执行的信道侦听的类型具体可以由网络设备通过下行控制信息(例如步骤S101的指示信息)指示。例如,可以通过调度该第一上行传输的至少一个UL grant通知。可选的,终端设备也可以通过现有的获取信道侦听类型的方式,获取终端设备在发送上述第一上行传输之前所执行的信道侦听的类型,对此不再赘述。
在信道侦听成功后,终端设备可以接入信道并可以连续占用信道一段时间。该连续占用信道的时间长度不超过第三信道侦听对应的MCOT长度。由于发送第一上行传输的第一时域资源为网络设备调度终端设备发送的上行传输。因此,可能存在如下问题,网络设备未为终端设备调度与该MCOT长度匹配的第一时域资源,导致终端设备在使用第一时域资源发送第一上行传输时无法占满整个MCOT。或者,网络设备为终端设备调度了与该MCOT长度匹配的第一时域资源,但终端设备未能在第一时域资源的第一个时间单元之前完成第一类信道侦听,而是在第一时域资源靠后的时间单元才接入信道,导致终端设备在使用第一时域资源的剩余时域资源发送第一上行传输时无法占满整个MCOT。
因此,在本实施例中,当终端设备所发送的第一上行传输的无法占满该MCOT,即,发送第一上行传输的第一时域资源的长度小于该MCOT的长度,上述终端设备可以使用该MCOT的剩余时间的部分或全部(即第二时域资源)继续传输第二上行传输,不需要再为第二上行传输执行第一类信道侦听。即,终端设备在第一时域资源上发送第一上行传输,在第二时域资源上发送第二上行传输,以使得网络设备可以在第一时域资源上接收第一上行传输,在第二时域资源上接收第二上行传输。也就是说,第三信道侦听对应的MCOT包括第一时域资源和第二时域资源。通过这种方式,可以提高MCOT的资源利用率以及信道利用率。
例如,假定网络设备为终端设备调度的用于发送第一上行传输的第一时域资源为#n+1子帧至#n+4子帧。终端设备在子帧#n完成第一类信道侦听(即第三信道侦听),该第一类信道侦听(即第三信道侦听)对应的MCOT长度为8个子帧,即,终端设备可以在#n+1子帧至#n+8子帧上发送上行传输。则终端设备在使用该第一时域资源发送第一上行传输时,#n+5子帧至#n+8子帧为空闲的子帧。因此,终端设备可以使用该#n+5子帧至#n+8子帧中的部分或全部子帧发送第二上行传输,不需要再为第二上行传输执行第一类信道侦听。
例如,假定网络设备为终端设备调度的用于发送第一上行传输的第一时域资源为#n+1子帧至#n+8子帧。终端设备在子帧#n+2完成第一类信道侦听(即第三信道侦听),该第一类信道侦听(即第三信道侦听)对应的MCOT长度为8个子帧,即,终端设备可以在#n+3子帧至#n+10子帧上发送上行传输。则终端设备在使用该第一时域资源的剩余可用资源 (#n+3子帧至#n+8子帧)发送第一上行传输时,#n+9子帧至#n+10子帧为空闲的子帧。因此,终端设备可以使用该#n+9子帧至#n+10子帧的部分或全部子帧发送第二上行传输,不需要再为第二上行传输执行第一类信道侦听。
反之,终端设备在发送第二上行传输之前,也可以对信道执行第三信道侦听。该第三信道侦听例如可以为前述所说的第一类信道侦听。在信道侦听成功后,终端设备可以接入信道并可以连续占用信道发送第二上行传输。该连续占用信道的最大时间长度不超过第三信道侦听对应的MCOT长度。若第二上行传输无法占满该第三信道侦听对应的MCOT,即,发送第二上行传输的第二时域资源的长度小于该MCOT的长度,则上述终端设备可以使用该MCOT的剩余时间的部分或全部(即第一时域资源)继续传输第一上行传输,不需要再为第一上行传输执行第一类信道侦听。即,终端设备在第一时域资源上发送第一上行传输,在第二时域资源上发送第二上行传输,以使得网络设备可以在第一时域资源上接收第一上行传输,在第二时域资源上接收第二上行传输。也就是说,第三信道侦听对应的MCOT包括第一时域资源和第二时域资源。通过这种方式,可以提高MCOT的资源利用率以及信道利用率。
对于第三信道侦听对应的MCOT包括第一时域资源和第二时域资源,可以有以下两种情况:
可选的,第一时域资源和第二时域资源的时间长度之和不超过第三信道侦听对应的最大信道占用时间。以第一时域资源包括子帧{#n+12,#n+13}为例,假定终端设备可以在第一上行传输之前发送第二上行传输,其中,终端设备在发送第二上行传输之前执行的第三信道侦听对应的MCOT长度为6ms,其中,1个子帧长度为1ms。则第二时域资源的长度可以为4ms,占用子帧{#n+8,#n+9,#n+10,#n+11},以使得第一时域资源与第二时域资源的长度之和不超过该MCOT长度。
可选的,第一时域资源的时间长度、第二时域资源的时间长度、第一时域资源和第二时域资源之间的空隙,这三者之和不超过第三信道侦听对应的最大信道占用时间。其中,上述所说的空隙可以为终端设备在信道上未发送任何上行信息的空闲时间。也就是说,第一时域资源和第二时域资源之间的空隙也计入到第三信道侦听对应的最大信道占用时间中。具体实现时,该空隙可以为不超过预定义时间长度的空闲时间。例如,该预定义时间长度为25us。可以理解,在第一时域资源和第二时域资源之间,25us以内的空闲时间(例如用于单时隙CCA的信道侦听的空隙)可以计入该第三信道侦听对应的最大信道占用时间,而超过25us的空闲时间可以不计入到该第三信道侦听对应的最大信道占用时间中。
可以理解,第一时域资源和第二时域资源在时间上不重叠。例如,当第一时域资源晚于第二时域资源时,第一时域资源的起始时刻不早于第二时域资源的结束时刻。当第一时域资源早于第二时域资源时,第二时域资源的起始时刻不早于第一时域资源的结束时刻。
可选的,在第一时域资源在时间上早于第二时域资源时,终端设备在发送第一上行传输之前,所执行的第一类信道侦听对应的MCOT长度,与,在第二时域资源在时间上早于第一时域资源时,终端设备在发送第二上行传输之前,所执行的第一类信道侦听对应的MCOT长度可以相同,也可以不同,具体可以根据第一上行传输的业务优先级和/或第二上行传输的业务优先级确定。
在本实施例中,上述第二时域资源为终端设备根据第一时域资源确定的时域资源。下 面从第一时域资源和第二时域资源在时间上连续或不连续的角度,对上述终端设备如何根据第一时域资源确定第二时域资源进行介绍和说明。
第一种情况:第一时域资源和第二时域资源在时间上连续。具体地,
图3为本申请实施例提供的一种时域资源的示意图。如图3所示,现有技术中,网络设备可能在同一个时间单元上调度至少两个终端设备,以使该至少两个终端设备可以使用正交的频域资源在同一时间单元上同时发送上行传输。即,该终端设备可能与其他终端设备在同一个时间单元上频分复用。因此,第一时域资源与第二时域资源在时间上连续可能会对其他终端设备造成干扰。
如图3(a)所示,以发送第二上行传输的第二时域资源晚于发送第一上行传输的第一时域资源为例,假定网络设备通过指示信息调度终端设备(#1)在子帧#n+8至#n+9发送第一上行传输,调度终端设备(#2)在子帧#n+8至#n+11发送上行传输,其中,终端设备(#1)与终端设备(#2)以频分复用的方式在子帧#n+8至#n+9上发送上行传输。
在终端设备(#1)通过执行第三信道侦听在子帧#n+8之前接入信道后,终端设备可以在子帧#n+8至#n+13占用信道。根据网络设备发送的指示信息,终端设备(#1)的第一上行传输在#n+9子帧结束。但是,由于终端设备(#1)并不知道网络设备为其他终端设备调度的时域资源和频域资源,所以,终端设备(#1)无法确定终端设备(#2)的上行传输是否在#n+9子帧结束,也无法确定发送第二上行传输的频域资源是否与终端设备(#2)的频域资源是否存在冲突。由于网络设备为终端设备半静态配置的用于发送第二上行传输的第二频域资源,通常会占用载波的全带宽。因此,若终端设备(#1)在#n+10子帧直接发送第二上行传输,则可能会对终端设备(#2)造成干扰。
如图3(b)所示,以发送第一上行传输的第一时域资源晚于发送第二上行传输的第二时域资源为例,假定网络设备通过指示信息调度终端设备(#1)在子帧#n+12至#n+13发送第一上行传输,调度终端设备(#2)在子帧#n+12至#n+13发送上行传输,其中,终端设备(#1)与终端设备(#2)以频分复用的方式在子帧#n+12至#n+13上发送上行传输。
在终端设备(#1)通过执行第三信道侦听在子帧#n+8之前接入信道后,终端设备可以在子帧#n+8至#n+13占用信道。此时,若终端设备(#1)在#n+8至#n+11发送第二上行传输。则由于发送第二上行传输的第二频域资源通常会占用载波的全带宽,因此,该第二上行传输会阻塞终端设备(#2)针对终端设备(#2)发送上行传输所执行的信道侦听,导致终端设备(#2)无法在子帧#n+12之前接入信道,影响终端设备(#2)的信道接入。
因此,为了避免上述问题,上述终端设备可以在发送第一上行传输所使用的第一频域资源、与、发送第二上行传输所使用的第二频域资源相同时,第一时域资源和第二时域资源在时间上可以连续。由于发送第二上行传输的第二频域资源通常会占用载波的全带宽,因此,当第二频域资源与第一频域资源相同时,说明终端设备不会与其他终端设备以频分复用的方式,在第一时域资源上发送数据,也不会出现其他终端设备在该终端设备发送第一上行传输之后的时域资源上连续的发送上行传输。因此,终端设备可以在发送第一上行传输之后紧接着发送第二上行传输,即,第一时域资源的结束时刻为第二时域资源的起始时刻。或者,可以在发送第二上行传输之后紧接着发送第一上行传输,即,第二时域资源的结束时刻为第一时域资源的起始时刻。
或者,在第一频域资源包括承载第一上行传输的载波上的全部可用频域资源时,第一 时域资源和第二时域资源在时间上连续。当第一频域资源包括承载第一上行传输的载波上的全部可用频域资源时,说明该载波上可以能够发送上行传输的所有可用频域资源全部被用于发送第一上行传输,无剩余频域资源被其他终端设备使用。因此,终端设备不会与其他终端设备以频分复用的方式,在第一时域资源上发送数据,也不会出现其他终端设备在该终端设备发送第一上行传输之后的时域资源上连续的发送上行传输。在该场景下,终端设备可以在发送第一上行传输之后紧接着发送第二上行传输,即,第一时域资源的结束时刻为第二时域资源的起始时刻。或者,可以在发送第二上行传输之后紧接着发送第一上行传输,即,第二时域资源的结束时刻为第一时域资源的起始时刻。其中,这里所说的载波也可以是子带(subband),该子带或载波对应终端设备执行信道侦听所侦听的频域范围。例如,终端设备在20Mhz载波上执行信道侦听以接入该载波上的信道,或者终端设备在20Mhz子带上执行信道侦听以接入该子带上的信道。可选的,该载波或该子带上的全部可用频域资源包括:该载波或该子带上的全部频域资源,或者,用于该终端设备在该载波或该子带上发送上行信息的全部频域资源。其中,该上行信息可以是数据信息,也可以包括数据信息、控制信息、参考信号中的至少一种。在一些实施例中,该载波或该子带上的全部可用频域资源不包括该载波或该子带上的保护带(guard band)。
或者,在第一频域资源包括承载第一上行传输的载波上的全带宽(full bandwidth)资源时,第一时域资源和第二时域资源在时间上连续。当第一频域资源包括承载第一上行传输的载波上的全带宽资源时,说明该载波上的所有频域资源全部被用于发送第一上行传输,无剩余频域资源被其他终端设备使用。因此,终端设备不会与其他终端设备以频分复用的方式,在第一时域资源上发送数据,也不会出现其他终端设备在该终端设备发送第一上行传输之后的时域资源上连续的发送上行传输。在该场景下,终端设备可以在发送第一上行传输之后紧接着发送第二上行传输,即,第一时域资源的结束时刻为第二时域资源的起始时刻。或者,可以在发送第二上行传输之后紧接着发送第一上行传输,即,第二时域资源的结束时刻为第一时域资源的起始时刻。其中,这里所说的载波也可以是子带(subband)。可选的,该载波或该子带上的全带宽资源包括:该载波或该子带上的全部频带资源,或者,用于该终端设备在该载波或该子带上发送上行信息的全部带宽资源。其中,该上行信息可以是数据信息,也可以包括数据信息、控制信息、参考信号中的至少一种。在一些实施例中,该载波或该子带上的全带宽资源不包括该载波或该子带上的保护带(guard band)。
或者,在第一频域资源包括承载第一上行传输的载波上的全部可用物理资源块时,第一时域资源和第二时域资源在时间上连续。即,在第一频域资源由该载波上全部能够用于发送上行传输的物理资源块组成时,说明该载波上的所有可用物理资源块全部被用于发送第一上行传输,无可用物理资源块被其他终端设备使用。因此,终端设备不会与其他终端设备以频分复用的方式,在第一时域资源上发送数据,也不会出现其他终端设备在该终端设备发送第一上行传输之后的时域资源上连续的发送上行传输。在该场景下,终端设备可以在发送第一上行传输之后紧接着发送第二上行传输,即,第一时域资源的结束时刻为第二时域资源的起始时刻。或者,可以在发送第二上行传输之后紧接着发送第一上行传输,即,第二时域资源的结束时刻为第一时域资源的起始时刻。其中,这里所说的载波也可以是子带(subband)。可选的,该载波或该子带上的全部可用物理资源块(physical resource block,PRB)包括:该载波或该子带上的全部频域资源,或者,用于该终端设备在该载波 或该子带上发送上行信息的全部物理资源块。其中,该上行信息可以是数据信息,也可以包括数据信息、控制信息、参考信号中的至少一种。在一些实施例中,该载波或该子带上的全部可用物理资源块不包括该载波或该子带上的保护带(guard band)。
可以理解,上述所示的第一时域资源和第二时域资源在时间上连续仅是一种示例。本领域技术人员可以理解的是,在不满足上述条件时或者在任意情况下,上述第一时域资源和第二时域资源也可以在时间上连续等,本实施例对此不进行限定。
应理解,第一时域资源和第二时域资源在时间上连续也称为,第一上行传输和第二上行传输在时间上连续。
在第一时域资源和第二时域资源在时间上连续、且第二时域资源早于第一时域资源时,上述终端设备可以根据第一时域资源的起始时刻或起始时间单元,确定第二时域资源的结束时刻或结束时间单元。例如,终端设备可以将第一时域资源的起始时刻作为第二时域资源的结束时刻,或者使第一时域资源的起始时间单元和第二时域资源的结束时间单元相邻。
在第一时域资源和第二时域资源在时间上连续、且第二时域资源晚于第一时域资源时,上述终端设备可以根据第一时域资源的结束时刻或结束时间单元,确定第二时域资源的起始时刻或起始时间单元。例如,终端设备可以使第二时域资源的起始时刻和第一时域资源的结束时刻相同,或者使第二时域资源的起始时间单元和第一时域资源的结束时间单元相邻。
其中,上述所确定的第二时域资源可以为网络设备为终端设备半静态配置的用于发送第二上行传输的GUL时域资源的子集,也可以非该GUL时域资源中的资源,对此不进行限定。例如网络设备通过高层信令和/或物理层控制信令半静态配置的GUL时域资源包括子帧{#1,#2},{#5,#6},…时,如果第一时域资源为子帧#4,则终端设备可以确定第二时域资源为{#5,#6}。又例如,网络设备通过半静态配置的GUL时域资源包括子帧{#1,#2},{#5,#6},{#9,#10}…时,如果第一时域资源为子帧#4,UL MCOT为6ms,则终端设备确定的第二时域资源为{#5,#6,#7,#8,#9},其中子帧#7、#8不包括在配置的GUL时域资源中。
可以理解,该第二上行传输早于该第一上行传输包括,发送该第二上行传输的第二时域资源对应的结束时刻或结束时间单元,不晚于发送该第一上行传输的第一时域资源的起始时刻或起始时间单元。该第二上行传输晚于该第一上行传输包括,发送该第二上行传输的第二时域资源的起始时刻或起始时间单元,不早于发送该第一上行传输的第一时域资源的结束时刻或结束时间单元。
其中,上述所说的起始时间单元为时域资源(第一时域资源或第二时域资源)所包含的至少一个时间单元中的第一个时间单元,或者,上述所说的起始时间单元为时域资源(第一时域资源或第二时域资源)所占用的至少一个时间单元中的第一个时间单元。结束时间单元为时域资源所包含的至少一个时间单元中的最后一个时间单元。可选的,上述起始时间单元可以是时域资源所包含的第一个子帧或者是时域资源所包含的第一个子帧的第一个时域符号(symbol)、也可以是时域资源所占的第一个子帧的第一个时域符号。该第一个时域符号可以属于该时域资源,也可以不属于该时域资源,例如该时域资源为子帧#n上的符号#1-符号#13,该起始时间单元为子帧#n上的符号#0。另外,如后面提到的,在起始时间单元用于发送预占用信号时,上述起始时间单元也可以是时域资源所在的至少一个子 帧中的第一个子帧的子帧起始边界(或者该第一个子帧的第一个符号的起始边界)到终端设备在时域资源所在的至少一个子帧中发送数据信息的起始时刻之间的时间单元。
可选的,在第一时域资源和第二时域资源在时间上连续、且第一时域资源在时间上早于第二时域资源时,终端设备发送第二上行传输(或第二时域资源)对应的起始时间单元用于承载数据信息,或者,预占用信号(reservation signal)。其中,预占用信号为数据信息或控制信息以外的其他类型的信号。预占用信号可以为填充信号、参考信号,例如解调参考信号(demodulation reference signal,DMRS)或探测参考信号(sounding reference signal,SRS),或数据符号的循环前缀(cyclic shift,CP)信号,或前导序列(preamble)。例如,假定协议规定第二上行传输的数据信息从某个时间单元的预定义时刻(例如从一个子帧的第2个符号)开始发送,且第一上行传输的结束时刻通常早于该第二上行传输的数据信息发送起始时刻,则上述终端设备可以在第一上行传输结束时刻与第二上行传输的数据信息发送起始时刻之间,发送预占用信号,以保证信道占用的连续性。假定协议规定第二上行传输的数据信息从某个时间单元的预定义时刻(例如从一个子帧的第2个符号)开始发送,且第一上行传输的结束时刻刚好在该第二上行传输的数据信息发送起始时刻,则上述终端设备可以直接发送第二上行传输的数据信息,不用发送预占用信号。
需要说明的是,当该第二上行传输(或第二时域资源)对应的起始时间单元用于承载数据信息时,终端设备在对该第二时域资源的第一个子帧或第一个时间单元执行速率匹配(rate matching)时,需要考虑该起始时间单元的数据信息。当该第二上行传输起始部分的时域资源用于承载预占用信号时,终端设备在对该第二时域资源的第一个子帧或第一个时间单元执行速率匹配(rate matching)时,不考虑该起始时间单元的数据信息。
可选的,在第一时域资源和第二时域资源在时间上连续、且第二时域资源在时间上早于第一时域资源时,终端设备发送第一上行传输的起始时间单元用于承载数据信息,或者,预占用信号。关于此部分的描述,可以参见上述关于“终端设备发送第二上行传输的起始时间单元用于承载数据信息,或者,预占用信号”的描述,对此不再赘述。
第二种情况:上述第一时域资源和第二时域资源在时间上不连续。具体地,
可选的,上述终端设备可以根据第一频域资源,确定第一时域资源和第二时域资源在时间上不连续。参照前述描述,在第一频域资源与第二频域资源不同时,第一时域资源和第二时域资源在时间上不连续。或者,在第一频域资源未包括承载第一上行传输的载波上的全部可用频域资源时,第一时域资源和第二时域资源在时间上不连续。或者,在第一频域资源未包括承载第一上行传输的载波上的全带宽资源(即,第一频域资源占用部分带宽partial bandwidth)时,第一时域资源和第二时域资源在时间上不连续。或者,在第一频域资源未包括承载第一上行传输的载波上的全部可用物理资源块时,第一时域资源和第二时域资源在时间上不连续。
应理解,第一时域资源和第二时域资源在时间上不连续也称为,第一上行传输和第二上行传输在时间上不连续。
可以理解,上述所示的第一时域资源和第二时域资源在时间上不连续仅是一种示例。本领域技术人员可以理解的是,在不满足上述条件时或者在任意情况下,上述第一时域资源和第二时域资源也可以在时间上不连续等,本实施例对此不进行限定。
在第一时域资源和第二时域资源在时间上不连续时,若第一时域资源在时间上早于第 二时域资源,则第一时域资源在时间上的结束时刻与第二时域资源在时间上的起始时刻之间可以间隔第一时间间隔。在该第一时间间隔内,上述终端设备可以执行第一信道侦听,以确定信道是否空闲。进而在信道空闲(即在对信道执行第一信道侦听成功)时,终端设备在第二时域资源上发送第二上行传输。即,网络设备接收的第二上行传输为终端设备在对信道执行第一信道侦听成功时,在第而时域资源上发送的上行传输。通过执行第一信道侦听的方式,可以避免因发送第二上行传输对其他正在发送上行传输的终端设备造成干扰。可选的,上述第一信道侦听为与第三信道侦听属于不同类的信道侦听(即终端设备在发送第一上行传输之前执行的信道侦听)。例如,上述第一信道侦听可以为短侦听类型的信道侦听,例如单时隙CCA。考虑到终端设备已经通过第三信道侦听抢占到信道,在第一时域资源未超出最大信道占用时间的情况下,可以继续最大信道占用时间剩余的时域资源,使用该执行一个短侦听类型的信道侦听接入信道发送第二上行传输,通过这种方式,可以使终端设备能够快速度的接入信道,完成第二上行传输的发送。
可以理解,上述第一时间间隔(也可以称为预留空闲时间或空隙)可以包括第一时域资源的结束时间单元的尾部,也可以包括第二时域资源的起始时间单元的头部,也可以既包含第一时域资源的结束时间单元的尾部也包含第二时域资源的起始时间单元的头部。即,第一时域资源的结束时间单元与第二时域资源的起始时间单元之间间隔第一时间间隔。当第一时间间隔包括第一时域资源的结束时间单元的尾部时,说明发送第一上行传输的最后一个时间单元的结束时刻或结束符号早于该最后一个时间单元的结束边界(例如最后一个子帧的结束边界)。当第一时间间隔包括第二时域资源的起始时间单元的头部时,说明发送第二上行传输的第一个时间单元的起始时刻或起始符号晚于该第一个时间单元的起始边界(例如第一个子帧的起始边界)。此时第二上行传输的起始时刻可以是终端设备自主决定的,也可以是预定义的,或者为高层信令配置的,对此不进行限定。
本申请实施例对上述第一时间间隔的长度不做限定。可选的,上述第一时间间隔可以大于或等于一个时间单元,也可以小于一个时间单元(例如一个子帧)。例如上述第一时间间隔为至少一个符号的时间长度,或者为一个符号的部分时间长度(小于一个符号的时间长度),或者为执行一个单时隙CCA的时间长度等。
可选的,在一些实施例中,上述第一时间间隔可以小于一个时间单元(例如一个符号或者一个子帧)的长度。即,通过第一时间间隔,使第二时域资源的起始时间单元(例如起始子帧)为第一时域资源的最后一个时间单元(例如结束子帧)之后的下一个时间单元(例如下一个子帧)。在该实现方式下,若终端设备在该下一个时间单元的起始时刻之前执行单时隙CCA未成功,则放弃发送第二上行传输。
可选的,第一时间间隔为网络设备通过高层信令配置的时间长度。
可选的,第一时间间隔为终端设备确定的,第一时间间隔大于或者等于第一时间间隔门限。其中,该第一时间间隔门限可以是预定义的,也可以是网络设备通过高层信令配置的。
在第一时域资源和第二时域资源在时间上不连续、且第一时域资源在时间上早于第二时域资源时,上述终端设备可以根据第一时域资源的结束时刻或结束时间单元,确定第二时域资源的起始时刻或起始时间单元。例如,终端设备可以使第一时域资源的结束时刻或者结束时间单元与第二时域资源的起始时刻或起始时间单元之间的时间间隔为第一时间 间隔。上述所确定的第二时域资源可以为网络设备为终端设备半静态配置的GUL时域资源的子集,也可以非该GUL时域资源中的资源等,如前所述,对此不进行限定。
相应地,在第一时域资源和第二时域资源在时间上不连续时,若第二时域资源在时间上早于第一时域资源,则第二时域资源在时间上的结束时刻与第一时域资源在时间上的起始时刻之间间隔第二时间间隔。在该第二时间间隔内,上述终端设备可以执行第二信道侦听,以确定信道是否空闲。进而在信道空闲(即在对信道执行第二信道侦听成功)时,终端设备在第一时域资源上发送第一上行传输。即,网络设备接收的第一上行传输为终端设备在对信道执行第二信道侦听成功时,在第一时域资源上发送的上行传输。通过执行第二信道侦听的方式,可以避免因发送第一上行传输对其他终端设备造成干扰。可选的,上述第二信道侦听为与第三信道侦听(即终端设备在发送第二上行传输之前执行的信道侦听)属于不同类的信道侦听。例如,上述第二信道侦听可以为短侦听类型的信道侦听,例如单时隙CCA。考虑到终端设备已经通过第三信道侦听抢占到信道,在第二时域资源未超出最大信道占用时间的情况下,可以继续最大信道占用时间剩余的时域资源,使用该执行一个短侦听类型的信道侦听接入信道发送第一上行传输,通过这种方式,可以使终端设备能够快速度的接入信道,完成第一上行传输的发送。
可以理解,上述第二时间间隔(也可以称为预留空闲时间或空隙)可以包括第二时域资源的结束时间单元的尾部,也可以包括第一时域资源的起始时间单元的头部,也可以既包含第二时域资源的结束时间单元的尾部也包括第一时域资源的起始时间单元的头部。当第二时间间隔包括第二时域资源的结束时间单元的尾部时,说明发送第二上行传输的最后一个时间单元的结束时刻或结束符号早于该最后一个时间单元的结束边界(例如最后一个子帧的结束边界)。当第二时间间隔包括第一时域资源的起始时间单元的头部时,说明发送第一上行传输的第一个时间单元的起始时刻或起始符号晚于该第一个时间单元的起始边界(例如第一个子帧的起始边界)。此时第二上行传输的结束时刻可以是终端设备自主决定的,也可以是预定义的,或者为高层信令配置的,对此不进行限定。
本申请实施例对上述第二时间间隔的长度不做限定。本申请实施例对上述第二时间间隔的长度不做限定。可选的,上述第二时间间隔可以大于或等于一个时间单元,也可以小于一个时间单元(例如一个子帧)。例如上述第二时间间隔为至少一个符号的时间长度,或者为一个符号的部分时间长度(小于一个符号的时间长度),或者为执行一个单时隙CCA的时间长度等。
可选的,在一些实施例中,上述第二时间间隔可以小于一个时间单元(例如一个符号或者一个子帧)的长度。即,通过第二时间间隔,使第一时域资源的起始时间单元(例如起始子帧)为第二时域资源的最后一个时间单元(例如结束子帧)之后的下一个时间单元(例如下一个子帧)。在该实现方式下,若终端设备在该下一个时间单元的起始时刻之前执行单时隙CCA未成功,则放弃发送第一上行传输。
可选的,第二时间间隔为网络设备通过高层信令配置的时间长度。
可选的,在一些实施例中,由于终端设备在第一上行传输之前可能需要执行基于随机回退的CCA(即第二信道侦听为基于随机回退的CCA),另外,其他与该终端设备频分复用的终端设备可能需要执行随机回退CCA,所以终端设备需要提前停止第二上行传输,以确保预留足够长的空闲时间给终端设备或者其他终端设备用于随机回退CCA的侦听。因此, 上述第二时间间隔可以大于或等于预设的第二时间间隔门限。其中,该第二时间间隔门限可以是预定义的,也可以是网络设备通过高层信令配置的。例如,终端设备在第一上行传输的起始子帧之前提前k个子帧停止发送第二上行传输,k为正整数,例如k=1或2或3。
在确定第一时域资源和第二时域资源在时间上不连续、且第二时域资源在时间上早于第一时域资源时,上述终端设备可以根据第一时域资源的起始时刻或起始时间单元,确定第二时域资源的结束时刻或结束时间单元。例如,终端设备可以使第一时域资源的起始时刻或者起始时间单元与第二时域资源的结束时刻或结束时间单元之间的时间间隔为第二时间间隔。上述所确定的第二时域资源可以为网络设备为终端设备半静态配置的GUL时域资源的子集,也可以非该GUL时域资源中的资源等,对此不进行限定。
图4为本申请实施例提供的另一种时域资源的示意图。如图4(a)所示,以发送第二上行传输的第二时域资源晚于发送第一上行传输的第一时域资源为例,假定网络设备通过指示信息调度终端设备(#1)在子帧#n+8至#n+9发送第一上行传输,其中,发送第一上行传输的第一频域资源包括承载第一上行传输的载波上的全带宽资源。
在终端设备(#1)通过执行第三信道侦听在子帧#n+8之前接入信道后,终端设备可以在子帧#n+8至#n+13占用信道。根据网络设备发送的指示信息,终端设备(#1)的第一上行传输在#n+9子帧结束。由于第一频域资源包括承载第一上行传输的载波上的全带宽资源时,说明该载波上的所有频域资源全部被用于发送第一上行传输,无剩余频域资源被其他终端设备使用。即,终端设备在#n+10子帧之前未与其他终端设备频分复用。因此,终端设备可以在#n+10子帧至#n+13占用信道发送第二上行传输。
如图4(b)所示,继续以发送第二上行传输的第二时域资源晚于发送第一上行传输的第一时域资源为例,假定网络设备通过指示信息调度终端设备(#1)在子帧#n+8至#n+9发送第一上行传输,调度终端设备(#2)在子帧#n+8至#n+11发送上行传输。其中,终端设备(#1)与终端设备(#2)以频分复用的方式在子帧#n+8至#n+9上发送上行传输。
在终端设备(#1)通过执行第三信道侦听在子帧#n+8之前接入信道后,终端设备可以在子帧#n+8至#n+13占用信道。根据网络设备发送的指示信息,终端设备(#1)的第一上行传输在#n+9子帧结束。但是由于第一频域资源并未包括承载第一上行传输的载波上的全带宽资源,为了避免对其他终端设备(例如,终端设备(#2))造成干扰,上述终端设备在发送第一上行传输之后,可以先停下来执行第一信道侦听,等在子帧#n+12上信道侦听成功之后,在子帧#n+12和#n+13上发送第二上行传输。
图5为本申请实施例提供的又一种时域资源的示意图。如图5(a)所示,以发送第二上行传输的第二时域资源早于发送第一上行传输的第一时域资源为例,假定网络设备通过指示信息调度终端设备(#1)在子帧#n+12至#n+13发送第一上行传输,其中,发送第一上行传输的第一频域资源包括承载第一上行传输的载波上的全带宽资源。
在终端设备(#1)通过执行第三信道侦听在子帧#n+8之前接入信道后,终端设备可以在子帧#n+8至#n+13占用信道。由于第一频域资源包括承载第一上行传输的载波上的全带宽资源,说明该载波上的所有频域资源全部被用于发送第一上行传输,无剩余频域资源被其他终端设备使用。即,终端设备在#n+12子帧不会与其他终端设备频分复用。因此,终端设备可以在#n+8子帧至#n+11占用信道发送第二上行传输。
如图5(b)所示,继续以发送第二上行传输的第二时域资源早于发送第一上行传输的 第一时域资源为例,假定网络设备通过指示信息调度终端设备(#1)在子帧#n+12至#n+13发送第一上行传输,调度终端设备(#2)在子帧#n+12至#n+13发送上行传输。其中,终端设备(#1)与终端设备(#2)以频分复用的方式在子帧#n+12至#n+13上发送上行传输。
在终端设备(#1)通过执行第三信道侦听在子帧#n+8之前接入信道后,终端设备可以在子帧#n+8至#n+13占用信道。由于第一频域资源未包括承载第一上行传输的载波上的全带宽资源,说明可能存在与终端设备(#1)进行频分复用的其他终端设备(例如终端设备(#2))。因此,为了避免对其他终端设备产生干扰,上述终端设备可以提前停止第二上行传输,以预留空闲执行第二信道侦听。以执行单时隙CCA为例,上述终端设备可以在#n+8子帧至#n+11的部分时间上占用信道发送第二上行传输。
本申请实施例提供的数据传输方法,终端设备在所发送的上行传输无法占满MCOT时,可以继续使用该未被占满的MCOT发送其他上行传输,可以提高MCOT的资源利用率和信道的利用率。
