  • the transmission node needs to send information and needs to do LBT first, it performs power detection on the surrounding nodes.

本申请要求于2019年08月02日提交国家知识产权局、申请号为201910712174.3、申请名称为“非授权频段上的上行传输方法及终端设备”的中国专利申请的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信领域，尤其涉及一种非授权频段上的上行传输方法及终端设备。
背景技术
在未来通信系统中，非授权频段可以作为授权频段的补充帮助运营商对服务进行扩容。为了与新空口(new radio，NR)部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。非授权频段的大带宽(80或者100MHz)能够减小基站和用户设备(user equipment，UE)的实施复杂度。由于非授权频段由多种技术(RATs)共用，例如WiFi、雷达、长期演进(long term evolution，LTE)授权频谱辅助接入(license assisted access，LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合规则以保证所有设备可以公平的使用该资源，例如先听后说(listen before talk，LBT)、最大信道占用时间(maximum channel occupancy time，MCOT)等规则。当传输节点需要发送信息、并需要先做LBT时，对周围的节点进行功率检测，当检测到的功率低于一个门限时，认为信道为空，传输节点可以进行发送。反之，则认为信道为忙，传输节点不能进行发送。传输节点可以是基站、UE、无线接入点(access point，AP)等等。
在LTE LAA中，在非授权频段，为了减少接入时延，UE可以不经过基站而进行自主上行传输(autonomous UL transmission，AUL)。基站通过无线资源控制(radio resource control，RRC)给UE配置AUL的时域资源。AUL操作可以通过下行控制信息(downlink control information，DCI)激活或者去激活。在AUL激活时，基站通过激活DCI通知UE AUL传输的频域资源等。UE在AUL资源上进行上行传输。在LTE LAA中，UE进行AUL传输前需要侦听信道，当侦听到信道为空时可以在不超过LBT priority class(优先级类)对应的MCOT内进行传输。此外，当UE可以共享基站的信道占用时间(channel occupancy time，COT)时，UE在共享COT内进行AUL传输前执行LBT操作。
在NR中，针对低时延业务或者周期业务的需求，NR支持上行半静态的配置授权(configured grant，CG)传输方式，减少信令交互流程，保证低时延要求。CG传输的资源可通过RRC信令半静态地配置，当业务数据到来时，UE可在CG的上行信道上发送数据。
基于帧的设备(frame based equipment，FBE)指设备的发送/接收定时采用周期结构，其周期为固定帧周期(fixed frame period，FFP)。对于基于FBE的上行传输， UE在每个FFP之前判断信道是否为空，以决定后续是否传输。对于基于调度的上行传输(scheduling-based UL，SUL)，当调度时延比剩余的FFP长时，则被调度数据会在下一个FFP内，且资源的时域起始位置可能不在FFP的边缘。此时UE不能在FFP之内做LBT。此外，配置的AUL的时域资源可能和FFP的起始边缘不对齐。相关解决方案是UE共享基站的COT，也就是说，所有上行传输都基于5G基站gNB的指示，即使是AUL传输，gNB也需要指示UE是否可以进行AUL传输。这种方式可以解决如上所述的问题，但是强制UE所有传输都要基于gNB的指示会带来额外的开销。此外，UE需要解调了gNB的指示才能开始UL传输，导致gNB无法在FFP的前半部分调度或配置上行传输，因此在一定程度上也降低了效率。

本公开的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(global system of mobile communication,GSM)，码分多址(code division multiple access，CDMA)系统，宽带码分多址(wideband code division multiple access wireless，WCDMA)，通用分组无线业务(general packet radio service，GPRS)，LTE、NR等。

图1是本公开的一个实施例中一种非授权频段上的上行传输方法的示意性流程图。非授权频段上的上行传输方法应用于终端设备，终端设备为基于帧的设备FBE。图1的方法可包括：
S102，根据上行资源与FBE的固定帧周期FFP之间的时域位置关系，侦听上行传输信道的闲忙状态，或，检测信道占用时间共享指示。
其中，信道占用时间共享指示由基站下发给终端设备。
S104，根据侦听结果或检测结果，确定是否利用上行资源进行上行传输。
本实施例中，上行资源为基站在下行控制信息DCI中指示的调度资源或基站通过无线资源控制RRC配置的配置授权CG传输资源；上行传输信道为FFP中用于上行传输的资源，上行资源为上行传输信道所在资源的部分或全部。其中，基站为FBE。
在本公开实施例中，通过根据上行资源与FBE的固定帧周期FFP之间的时域位置关系，侦听上行传输信道的闲忙状态或检测信道占用时间共享指示，进而根据侦听结果或检测结果确定是否利用上行资源进行上行传输，而无需每次上行传输均基于基站的指示，可减少信令开销。另外，根据上行资源的时域位置有针对性地选择侦听操作或检测操作，能够实现FBE上行传输时的侦听或检测操作的灵活性，从而提高上行传输的效率。
下面，将结合具体的实施例，对本公开实施例的方法作进一步的描述。
图2(a)～2(b)是本公开的一个实施例中的上行资源与FBE的FFP之间的时域位置关系示意图。在图2(a)～2(b)中，以斜线填充的资源块表示上行资源。可看出，在图2(a)中，上行资源的时域起始位置为FBE的FFP的起始时刻，即上行资源的时域起始位置与FFP的起始位置(FFP边缘)对齐；在图2(b)中，上行资源的时域起始位置不为FBE的FFP的起始时刻，即上行资源的时域起始位置与FFP的起始位置(FFP边缘)不对齐。
在一个实施例中，若上行资源的时域起始位置为FFP的起始时刻(如图2(a)所示)，则在FFP的起始时刻之前侦听上行传输信道的闲忙状态。具体的，非授权频段上的上行传输方法可执行为如图3所示的步骤。
S301，若上行资源的时域起始位置为FFP的起始时刻，则在当前FFP的起始时刻之前的空闲时段侦听上行传输信道是否空闲。若否，即若侦听到上行传输信道繁忙，则执行S302；若是，即若侦听到上行传输信道空闲，则执行S303。
S302，在下一个FFP的起始时刻之前的空闲时段侦听上行传输信道是否空闲。若否，即若侦听到上行传输信道繁忙，则继续执行S302；若是，即若侦听到上行传输信道空闲，则执行S303。
其中，下一个FFP的起始时刻之前的空闲时段即为当前FFP的空闲时段。
S303，利用上行资源进行上行传输。
图4是本实施例中的一种时域资源示意图。图4中示出了两个连续的FFP，每个FFP的起始时刻之前各有一段空闲时段(如图4中以右斜线填充的时段)，每个FFP的起始时刻之前的空闲时段即为上一个FFP的空闲时段，各FFP的空闲时段之前的时段为对应FFP的信道占用时间COT，且以左斜线填充的资源块表示上行资源。本实施例中，上行资源的时域起始位置为FFP的起始时刻，假设图4中所示的第一个FFP即为当前FFP，那么终端设备在第一个FFP的起始时刻之前的空闲时段侦听上行传输信道是否空闲。若侦听到信道空闲，则利用上行资源进行上行传输。若侦听到信道繁忙，则在第二个FFP的起始时刻之前的空闲时段侦听上行传输信道是否空闲。若侦听到信道空闲，则利用上行资源进行上行传输。若侦听到信道繁忙，则在第三个FFP的起始时刻之前的空闲时段侦听上行传输信道是否空闲(图4中未示出)。
由本实施例可以看出，终端设备在上行资源的时域起始位置为FBE的FFP的起始时刻时，能够在FFP的空闲时段侦听信道闲忙状态，并在侦听到信道空闲时间进行上行传输，从而避免由基站指示时所带来的信令开销，提高了上行传输的效率。
在一个实施例中，若上行资源的时域起始位置不为FBE的FFP的起始时刻(如图2(b)所示)，则检测信道占用时间共享指示。具体的，非授权频段上的上行传输方法可执行为如图5所示的步骤。
S501，若上行资源的时域起始位置不为FFP的起始时刻，则在FFP的指定OFDM符号时间内检测信道占用时间共享指示。
其中，指定OFDM符号时间(简称OS)为FFP的前N个OFDM符号时间；该前N个OFDM符号时间位于上行资源的时域起始位置之前。
S502，当检测到信道占用时间共享指示时，在当前FFP的信道占用时间COT内、上行资源的时域起始位置之前，侦听上行传输信道是否空闲。
S503，若侦听到上行传输信道空闲，则利用上行资源进行上行传输。
图6是本实施例的一种时域资源示意图。在图6中，以左斜线填充的资源块表示上行资源，FFP包括信道占用时间COT和空闲时段(图6中以右斜线填充的时段)，前N个OS位于上行资源的时域起始位置之前，即位于图6所示的以左斜线填充的资源块之前。一般来说，前N个OS是物理下行控制信道(physical downlink control channel,PDCCH)的发送位置，在图6中，PDCCH采用左右斜线交叉的方式填充。当终端设备检测到基站下发的信道占用时间共享指示后，在当前FFP的信道占用时间COT内、上行资源的时域起始位置之前(如图6所示的以竖线方式填充的位置)侦听上行传输信道是否空闲，即进行信道空闲估计CCA。
由上述实施例可看出，终端设备的上行资源的时域起始位置不为FBE的FFP的起始时刻时，能够在FFP的上行资源的时域起始位置之前检测信道占用时间共享指示，并在检测到信道占用时间共享指示后，在上行资源的时域起始位置之前执行信道侦听操作，从而实现共享基站信道占用时间，提高了上行传输的效率。
下面，本公开实施例以进行CG传输的FBE UE为例进行说明。假设配置CG传输资源的时域起始位置与FFP的起始位置对齐，这样可以保证UE在空闲时段做完信道空闲估计CCA后可以立即进行CG传输，如图7中的FFP2(固定帧周期2)所示。此外，考虑到FFP长度与CG传输资源的配置周期可能不能完全匹配，传输传输资源 可能配置在FFP中的任意位置，如图7中的FFP1(固定帧周期1)所示。
UE根据配置的CG传输资源的时域位置和FFP的起始位置是否对齐，决定是否自己做先听后说(listen before talk,LBT)进行传输，还是共享基站的COT。例如图7中，在FFP1(固定帧周期1)内，CG传输资源与FFP1的起始位置不对齐，则UE不能直接在FFP之前做LBT进行传输。此时UE在FFP的前几个OS上检测COT共享指示，其中，前几个OS传输图7所示的物理下行控制信道PDCCH。当基站侦听到信道为空，并在PDCCH中向UE发送COT共享指示时，UE在检测到COT共享指示后方可以在基站的COT内做单次LBT(one-shot LBT)，当侦听到信道为空时开始进行CG传输。在FFP2(固定帧周期2)中，CG传输资源的时域起始位置与FFP2的起始位置对齐，因此UE在FFP2中进行CG传输时，直接做LBT，当侦听到信道为空则开始CG传输。
下面，本公开实施例以进行基于调度传输的FBE UE为例进行说明。假设调度资源的时域起始位置与FFP的起始位置对齐，这样可以保证UE在空闲时段做完信道空闲估计CCA后可以立即进行上行传输，如图8中的FFP2(固定帧周期2)所示。此外，考虑到UE能力、调度时延等问题，调度的传输资源可能配置在FFP中的任意位置，如图8中的FFP3(固定帧周期3)所示。
UE根据调度资源的时域起始位置和FFP的起始位置是否对齐，决定是否自己做LBT进行传输，还是共享基站的COT进行传输。例如图8中，资源块上方的虚线箭头表示资源调度关系，资源块下方的虚线箭头表示COT共享指示。在FFP3内，调度的物理上行共享信道PUSCH资源与FFP3的起始位置不对齐，则UE不能直接在FFP3之前做LBT进行传输。此时UE在FFP3的前几个OS上检测COT共享指示，其中，前几个OS传输图8所示的物理下行控制信道PDCCH。当基站侦听到信道为空，并向UE发送COT共享指示时，UE在检测到COT共享指示后方可以在基站的COT内做单次LBT，当侦听到信道为空时开始PUSCH传输。在FFP2中，调度的PUSCH资源的时域起始位置与FFP2的起始位置对齐，因此UE在FFP2中进行传输时，直接在FFP2之前做LBT，当侦听到信道为空则开始PUSCH传输。
图9是本公开的另一个实施例中一种非授权频段上的上行传输方法的示意性流程图。非授权频段上的上行传输方法应用于基站，基站为基于帧的设备FBE。图9的方法可包括：
S902，向终端设备配置或指示上行资源；终端设备为基于帧的设备FBE。
该步骤中，基站向终端设备配置或指示上行资源时，可通过以下任一种方式实现：
(1)在向终端设备发送的下行控制信息DCI中指示调度资源；或，
(2)通过无线资源控制RRC配置CG传输资源，并将CG传输资源发送至终端设备。
S904，若上行资源的时域起始位置不为FBE的固定帧周期FFP的起始时刻，则在上行资源所在的固定帧周期FFP之前执行信道侦听操作。
在一个实施例中，执行S904时，基站在FFP之前侦听下行传输信道的闲忙状态；若侦听到下行传输信道空闲，则向终端设备下发信道占用时间共享指示；该信道占用时间共享指示用于指示终端设备可共享FFP的信道占用时间COT。
在本公开实施例中，基站向终端设备配置或指示上行资源后，仅在上行资源的时 域起始位置不为FBE的固定帧周期FFP的起始时刻时执行信道侦听操作，因此实现了共享信道占用时间，一定程度上提高了传输效率。
图10是本公开的另一个实施例中一种非授权频段上的上行传输方法的示意性流程图。本实施例中，非授权频段上的上行传输方法应用于终端设备及基站，其中，终端设备和基站可以是FBE。图10的方法可包括：
S1001，基站向终端设备配置或指示上行资源。
其中，基站可通过以下任一种方式向终端设备配置或指示上行资源：
(1)在向终端设备发送的下行控制信息DCI中指示调度资源；或，
(2)通过无线资源控制RRC配置CG传输资源，并将CG传输资源发送至终端设备。
S1002，若上行资源的时域起始位置为FFP的起始时刻，则终端设备在当前FFP的起始时刻之前的空闲时段侦听上行传输信道的闲忙状态。
S1003，当侦听到上行传输信道空闲时，利用上行资源进行上行传输。
S1004，若上行资源的时域起始位置不为FFP的起始时刻，则基站在上行资源所在的FFP之前侦听下行传输信道的闲忙状态，且终端设备在FFP的前N个OFDM符号时间内检测信道占用时间共享指示。
其中，信道占用时间共享指示由基站下发给终端设备，前N个OFDM符号时间位于上行资源的时域起始位置之前。
S1005，当基站侦听到下行传输信道空闲，则向终端设备下发信道占用时间共享指示。
其中，信道占用时间共享指示用于指示终端设备可共享FFP的信道占用时间COT。
S1006，终端设备接收到信道占用时间共享指示后，在当前FFP的信道占用时间COT内、上行资源的时域起始位置之前，侦听上行传输信道是否空闲。
该步骤之后，当侦听到上行传输信道空闲时，利用上行资源进行上行传输，即执行S1003。
在本公开实施例中，终端设备在上行资源的时域起始位置为FFP的起始时刻时，能够在前一个FFP的空闲时段侦听信道闲忙状态，并在侦听到信道空闲时间进行上行传输；并且，在上行资源的时域起始位置不为FFP的起始时刻时，能够在FFP的前N个OS内检测信道占用时间共享指示，并在检测到信道占用时间共享指示后执行信道侦听操作，而无需每次上行传输均基于基站的指示，可减少信令开销。并且实现了FBE上行传输时的侦听或检测操作的灵活性，提高了上行传输的效率。
