背景技术
在移动通信***中,非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。由于非授权频段由多种无线接入技术共用,因此非授权频段在使用时必须符合一定规则(regulation)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时,需要先做LBT对周围的节点进行功率检测(Energy Detection,ED),当检测到的功率低于一个门限时,认为信道为空(idle),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。传输节点开始传输后,占用的信道时间(Channel Occupancy Time,COT)不能超过MCOT。
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,其周期为固定帧长(Fixed Frame Period)。FBE节点采用基于LBT的信道接入机制来占用信道,其中发起包含一次或多次连续传输的传输序列的节点称之为发起节点(Initiating Device),其它节点称之为响应节点(Responding Device)。进一步地,在某个Fixed Frame Period的开始时刻启动传输之前,发起节点将执行LBT,也就是信道空闲估计(Clear Channel Assess,CCA),如果判断为空闲,则可以立即发送,否则在紧接着的Fixed Frame Period时长内都不允许发送。但是相关技术中,没有在非授权频段下FBE设备如何 进行配置授权传输的方式,以及当上行传输资源时域位置与固定帧的起始边缘不一致时的传输方案。

请参见图1,图1示出本公开实施例可应用的一种无线通信***的框图。无线通信***包括终端11和网络设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet  Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备,需要说明的是,在本公开实施例中并不限定终端11的具体类型。网络设备12可以是基站或核心网,其中,上述基站可以是5G及以后版本的基站(例如:gNB、5G NR NB等),或者其他通信***中的基站(例如:eNB、WLAN接入点、或其他接入点等),其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本公开实施例中仅以NR***中的基站为例,但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端11通信,在各种示例中,基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中,这些基站中的一些可以通过回程链路直接或间接地彼此通信,回程链路可以是有线或无线通信链路。无线通信***可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如,每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如,参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信***可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术,诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信***中的通信链路可包括用于承载上行链路(Uplink,UL)传输(例如,从终端11到网络设备12)的上行链路,或用于承载下行链路(Downlink,DL)传输(例如,从网络设备12到终端11)的下行链路。UL传输还可被称为反向链路传输,而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地,上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
本公开实施例的非授权频段的信息传输方法,应用于终端,如图2所示,该方法包括以下步骤:
步骤21:对第一传输信道进行侦听,第一传输信道采用第一固定帧长。
其中,本公开实施例的终端可以是FBE设备,终端支持的固定帧长(Fixed Frame Period)的取值集合可以设备制造商预配置,例如支持的固定帧长要求都位于1~10ms范围内。其中终端可以在某个固定帧长的开始时刻启动传输,终端还可以更改其当前应用的固定帧长,但是更改频度不能高于200ms一次。
其中,第一传输信道采用第一固定帧长可以是:第一传输信道采用第一固定帧长的帧结构。在第一固定帧长的开始时刻之前(或称为启动传输之前),终端可执行LBT,如信道空闲估计(Clear Channel Assess,CCA)。其中,值得指出的是,终端可采用特定侦听类型对第一传输信道进行侦听。侦听类型包括但不限于:侦听类型1(category 1),侦听类型2(category 2)和侦听类型4(category4)。category1的LBT是终端不做LBT,又可称为立即传输(immediate transmission)。category 2的LBT是一次侦听(one-shot LBT),即终端在传输前做一次LBT(即做一次CCA),信道空闲则进行传输,信道为忙则不传输。category 4的LBT是基于回退(back-off)的信道侦听机制,当终端侦听到信道为忙时,进行回退,继续做侦听,直到侦听到信道为空,则进行传输。可选地,本公开实施例中的终端可采用但不限于以上侦听类型中的一种进行信道侦听。
步骤22:在侦听到信道空闲的情况下,在第一传输信道上,发送上行信息。
其中,终端在CCA时判断为信道空闲,则可以在紧接着的第一固定帧长内发送。以侦听类型为category 2为例,终端紧邻(immediately before)第一 固定帧长时域起始位置处,对第一传输信道进行一次侦听,若终端在做CCA时判断信道为忙,则在紧接着的第一固定帧长内都不允许发送。其中,本公开实施例中在紧邻第一固定帧长时域起始位置的位置可参见图3中终端进行CCA的位置,该位置与第一固定帧长相邻,且在第一固定帧长开始之前。
在本公开的一种实施例中,终端还可以:在第二传输信道上,接收下行信息;其中,第二传输信道采用第二固定帧长。这里指的是网络设备对应第二固定帧长,或者说,终端采用第二固定帧长进行接收。其中,第二固定帧长可以与第一固定帧长相同,这里所说的相同指的是第二固定帧长的持续时间与第一固定帧长的持续时间相同。另外,第二固定帧长也可以与第一固定帧长不同,这里所说的不同指的是第二固定帧长的持续时间与第一固定帧长的持续时间不同。值得指出的是,本公开实施例并不对帧结构做具体限定,例如在第二固定帧长与第一固定帧长的持续时间相同的情况下,第二固定帧长的帧结构可以与第一固定帧长的帧结构相同或不同。
本公开实施例中可以灵活地为终端配置第一固定帧长(fixed frame period)。此时,终端和网络设备各自对应的固定帧长可以保持一致,也可以不一致。以网络设备对应的第二固定帧长与终端对应的第一固定帧长不同为例,如图3所示,终端和网络设备分别对应长度不一致的固定帧长。也就是说,网络设备和终端的固定帧长可以不一致,或者说网络设备和终端各自的发送和接收的固定帧长不一致。在本公开实施例中,配置的固定帧长是从发送端的角度定义的,对应的接收端按照发送端的固定帧长进行接收,如图3所示,图中虚线部分为接收资源。这样,网络设备和终端灵活的配置固定帧长,可减少不必要的资源浪费,提高资源利用率。
可选地,该方法还可以包括:获取第一固定帧长和第二固定帧长中的至少一项。可选地,在终端和网络设备各自对应一固定帧长时,网络设备可将各自对应的固定帧长发送给终端,例如网络设备可通过无线资源控制(Radio Resource Control,RRC),将第一固定帧长和第二固定帧长中的至少一项发送给终端。另外第一固定帧长和第二固定帧长也可以是预定义的,如协议约定。
可选地,该方法还可以包括:终端上报第一固定帧长,即终端将自己对应的固定帧长发送给网络设备,以便于网络设备基于第一固定帧长进行接收。
进一步地,第五代(5th Generation,5G)移动通信***,或者称为新空口(New Radio,NR)***,需要适应多样化的场景和业务需求,NR***的主要场景包括移动宽带增强(enhanced Mobile Broadband,eMBB)通信、大规模物联网(massive Machine Type Communications,mMTC)通信和超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications,URLLC),这些场景对***提出了高可靠、低时延、大带宽和广覆盖等要求。在FBE的上行传输对于每个Fixed Frame Period只有一次侦听机会的情况下,若CCA抢占失败,整个Fixed Frame Period均不可用,产生较大时延,可能无法满足NR***的低时延要求。
为了降低NR***非授权频段下传输的时延,***支持上行半静态的配置授权传输(configured grant),以减少信令交互流程,保证低时延要求。其中,配置授权传输资源可通过无线资源控制(Radio Resource Control,RRC)信令半静态地配置,当业务数据到来时,终端可在配置授权传输资源(如物理上行共享信道PUSCH)上发送数据。另外,对于基于调度的上行传输(Scheduling-based UpLink,SUL),当调度时延比剩余的固定帧长还长时,则被调度数据会在下一个固定帧长内,但调度数据的传输资源的时域起始位置可能未与固定帧长的时域起始位置对齐,如基于调度的传输资源的时域起始位置不在第一固定帧长的边缘。在该场景下,步骤22包括:在第一传输信道中的上行传输资源上,发送上行信息;其中,上行传输资源为配置授权传输资源或基于调度的传输资源。
以上行传输资源为配置授权传输资源为例,终端可以不经过网络设备授权而进行自主上行传输。终端在传输之前,对第一传输信道进行侦听,若侦听到信道空闲,则可以在第一传输信道中的配置授权传输资源上发送上行信息。
另外,上行传输资源还可以是基于调度的传输资源,终端在传输之前,对第一传输信道进行侦听,若侦听到信道空闲,则可以在第一传输信道中的基于调度的传输资源上,按照DCI信息发送上行信息。
进一步地,本公开实施例中对第一传输信道进行侦听所采用的侦听类型可以是category 2的LBT。也就是说,为了与FEB终端的信道接入机制保持 统一,本公开实施例的终端也采用category 2的LBT对第一传输信道进行侦听,例如进行配置授权传输的FBE终端采用category 2的LBT信道接入机制。具体地,步骤21包括:对第一传输信道进行一次侦听。
进一步地,为了保证FEB终端在CCA后可以立即进行配置授权传输或调度传输,第一传输信道中上行传输资源的时域起始位置与第一固定帧长的时域起始位置对齐。例如对于进行配置授权传输的FBE终端,配置授权传输资源的时域起始位置与第一固定帧长的时域起始位置对齐,这样可以保证终端在做完CCA后可以立即进行配置授权传输。
此外,第一传输信道中上行传输资源的时域起始位置也可以与第一固定帧长的时域起始位置未对齐。对于该场景,终端无法在对第一传输信道进行CCA后,立即进行上行传输,但终端可按照第一方式在上行传输资源上发送上行信息。下面本公开实施例将结合不同方式对上行传输方式做进一步说明。如图4所示,上行传输资源的时域起始位置和第一固定帧长的时域起始位置不对齐。如当配置授权传输资源的时域起始位置和第一固定帧长的时域起始位置不对齐,或者,网络设备对终端进行跨帧(cross frame)调度时,某个固定帧长上的调度资源的时域起始位置与该固定帧长的时域起始位置不对齐。此时,若终端在第一固定帧长的第一传输信道之前做侦听,检测到信道为空,终端无法立即进行传输,为了解决这个问题,可以但不限于采用以下几种方法进行传输。
方式一、在上行传输资源的时域起始位置到达之前,发送其他上行信号;在上行传输资源上,发送上行信息。
该方式下,终端在对第一传输信道进行侦听确定信道空闲的情况下,例如终端在紧邻第一固定帧长的时域起始位置处进行侦听确定信道空闲的情况下,终端在第一固定帧长的时域起始位置与上行传输资源的时域起始位置之间,可发送其他上行信号。这里所说的其他上行信号指的是除免调度上行信息或调度上行信息之外的其他信号,如其他上行数据或信令。如图5所示,终端在第一固定帧长开始之前做category 2的LBT,即做一次CCA,若检测到信道空闲,则终端发送其他上行数据或者信令直到上行传输资源开始,例如终端在侦听到信道空闲后,先发送探测参考信号(Sounding Reference Signal, SRS)填充未分配资源,直到上行传输资源开始。
方式二、在上行传输资源的时域起始位置到达之前进行侦听;在侦听到信道空闲的情况下,在上行传输资源上发送上行信息。
该方式下,终端在对第一传输信道进行侦听确定信道空闲的情况下,例如终端在紧邻第一固定帧长的时域起始位置处进行侦听确定信道空闲的情况下,终端在上行传输资源之前可先做侦听,以确保上行传输资源可用,在侦听到上行传输资源空闲的情况下,在上行传输资源上发送上行信息。其中,值得指出的是,对上行传输资源进行侦听的方式包括但不限于:
侦听方式1、在上行传输资源的时域起始位置到达之前,对第一传输信道进行持续侦听。
该方式下,终端在对第一传输信道进行侦听确定信道空闲的情况下,例如终端在紧邻第一固定帧长的时域起始位置处进行侦听确定信道空闲的情况下,终端在第一固定帧长的时域起始位置与上行传输资源的时域起始位置之间,可持续侦听。如图6所示,终端在第一固定帧长开始之前做category 2的LBT,即做一次CCA,若检测到信道空闲,终端继续进行category 2的LBT,直到终端的上行传输资源前。其中值得指出的是,在该方式下,终端在上行传输资源之前持续做LBT,且每次LBT均显示信道空闲,这样终端可以在上行传输资源上进行上行传输。
侦听方式2、在紧邻上行传输资源的时域起始位置处,对第一传输信道进行一次侦听。
该方式下,终端在对第一传输信道进行侦听确定信道空闲的情况下,例如终端在紧邻第一固定帧长的时域起始位置处进行侦听确定信道空闲的情况下,终端进一步在紧邻上行传输资源时域起始位置处,可进行一次侦听。如图7所示,终端在第一固定帧长开始之前做category 2的LBT,即做一次CCA,若检测到信道空闲,终端进一步在紧邻上行传输资源的时域起始位置处,再做一次category 2的LBT,若侦听到信道空闲,则可以立即在上行传输资源上进行上行传输。其中,本公开实施例中在紧邻上行传输资源时域起始位置处进行侦听,侦听结束后立即进入上行传输资源,其中,紧邻上行传输资源时域起始位置的位置指的是图7中进行CCA的位置,该位置与上行传输资源 相邻。
在该方式二下,终端在侦听到信道为忙的情况下,放弃上行传输资源。这里所说的侦听到信道为忙可以是:针对侦听方式1,若连续侦听过程中有一次LBT检测到信道为忙,则终端停止侦听并放弃该上行传输资源,即在该第一固定帧长的第一传输信道内不进行传输。针对侦听方式2,若紧邻上行传输资源的一次LBT检测到信道为忙,则终端放弃该上行传输,即在该第一固定帧长的第一传输信道内不进行传输。
方式三、根据网络设备的指示信息,在上行传输资源上发送上行信息。
该方式下,在网络设备的指示下进行上行传输。具体地,该方式包括:在接收到指示信息后,在上行传输资源的时域起始位置到达之前进行一次侦听;在侦听到信道空闲的情况下,在上行传输资源上,发送上行信息。例如终端在收到指示信息后,在紧邻上行传输资源时域起始位置处做category 2的LBT,若检测到信道为空,则在上行传输资源上进行上行传输。
进一步地,根据网络设备的指示信息,在上行传输资源上发送上行信息的步骤之前还包括:接收指示信息,该指示信息用于指示:允许终端共享网络设备的固定帧长或者信道占用时长。例如网络设备在一个固定帧长开始之前做category 2的LBT,当检测到信道空闲时,网络设备指示终端可以共享(share)该固定帧长(fixed frame period)或信道占用时长(COT)进行传输。
本公开实施例中,当配置传输资源或基于调度的传输资源的时域起始位置与固定帧长的时域起始边缘不对齐时,若在固定帧长开始前做LBT,且检测到信道为空,则可以在实际传输之前再进行LBT,或者发送其他信号填充固定帧长边缘和上行传输资源之间的间隙(gap),或者基于网络设备的指示信息进行传输。
本公开实施例的非授权频段的信息传输方法中,终端对采用第一固定帧长的第一传输信道进行侦听,在侦听到信道空闲时才可在第一传输信道上发送信息,使得FBE设备可在非授权频段上进行信息传输。另外终端和网络设备各自对应独自的固定帧长,配置方式更加灵活,可降低资源浪费率,提高资源利用率。进一步地,终端还可采用与FEB信道接入机制一致的侦听类型进行信道侦听。
以上实施例介绍了不同场景下的非授权频段的信息传输方法,下面将结合附图对与其对应的终端做进一步介绍。

值得指出的是,本公开实施例的终端对采用第一固定帧长的第一传输信道进行侦听,在侦听到信道空闲时才可在第一传输信道上发送信息,使得FBE设备可在非授权频段上进行信息传输。另外终端和网络设备各自对应独自的固定帧长,配置方式更加灵活,可降低资源浪费率,提高资源利用率。进一 步地,终端还可采用与FEB信道接入机制一致的侦听类型进行信道侦听。

以上实施例从终端侧介绍了本公开的非授权频段的信息传输方法,下面本实施例将结合附图对网络设备方法做进一步介绍。
如图10所示,本公开实施例的非授权频段的信息传输方法,应用于网络设备侧,该方法包括以下步骤:
步骤101:在第一传输信道上,接收上行信息;其中,第一传输信道采用第一固定帧长。
其中,本公开实施例的网络设备可以是FBE设备,网络设备支持的固定帧长为一取值集合中的值,网络设备可以在某个固定帧长的开始时刻启动传输。
其中,第一传输信道采用第一固定帧长可以是:第一传输信道采用第一固定帧长的帧结构。在第一固定帧长的开始时刻之前(或称为启动传输之前),终端可执行LBT,当LBT判断为信道空闲,终端可以在紧接着的第一固定帧长内发送。相应地,网络设备可在第一固定帧长内进行接收。
进一步地,本公开实施例的网络设备在发送时,还可包括以下步骤:对第二传输信道进行侦听;在侦听到信道空闲的情况下,在第二传输信道上发送下行信息;其中,第二传输信道采用第二固定帧长。相应的,终端在第二传输信道上,接收下行信息。其中,网络设备对应第二固定帧长,网络设备采用第二固定帧长发送,同时,终端采用第二固定帧长进行接收。进一步地,本公开实施例中对第二传输信道进行侦听所采用的侦听类型可以是category2的LBT。也就是说,为了与FEB终端的信道接入机制保持统一,本公开实施例的网络设备也采用category 2的LBT对第二传输信道进行侦听。
其中,第二固定帧长可以与第一固定帧长相同,这里所说的相同指的是第二固定帧长的持续时间与第一固定帧长的持续时间相同。另外,第二固定帧长也可以与第一固定帧长不同,这里所说的不同指的是第二固定帧长的持续时间与第一固定帧长的持续时间不同。另外,值得指出的是,本公开实施例并不对帧结构做具体限定,例如在第二固定帧长与第一固定帧长的持续时间相同的情况下,第二固定帧长的帧结构可以与第一固定帧长的帧结构相同或不同。本公开实施例中可以灵活地为终端配置第一固定帧长。此时,终端 和网络设备各自对应的固定帧长可以保持一致,也可以不一致。这样,网络设备和终端灵活的配置固定帧长,可减少不必要的资源浪费,提高资源利用率。
进一步地,本公开实施例的网络设备还可执行:向终端发送第一固定帧长和第二固定帧长中的至少一项。可选地,在终端和网络设备各自对应一固定帧长时,网络设备可将各自对应的固定帧长发送给终端。
进一步地,网络设备还包括:接收第一固定帧长。相应的,终端上报第一固定帧长,即终端将自己对应的固定帧长发送给网络设备,以便于网络设备基于第一固定帧长进行接收。
其中,本公开实施例中步骤1101包括:在第一传输信道中的上传输资源上,接收上行信息;其中,上行传输资源为配置授权传输资源或基于调度的传输资源。以上行传输资源为配置授权传输资源为例,配置授权传输资源可以是网络设备半静态配置给终端,这样当有业务数据到来时,终端可在配置授权传输资源上发送数据,而无需进行其他信令交互流程,可降低数据传输的时延。
进一步地,为了保证FEB终端在CCA后可以立即进行配置授权传输或调度传输,第一传输信道中上行传输资源的时域起始位置与第一固定帧长的时域起始位置对齐。例如对于进行配置授权传输的FBE终端,配置授权传输资源的时域起始位置与第一固定帧长的时域起始位置对齐,这样可以保证终端在做完CCA后可以立即进行配置授权传输。
此外,第一传输信道中上行传输资源的时域起始位置与第一固定帧长的时域起始位置未对齐。对于该场景,终端无法在对第一传输信道进行CCA后,立即进行上行传输,但终端可按照第一方式在上行传输资源上发送上行信息。例如当配置传输资源或基于调度的传输资源的时域起始位置与固定帧长的时域起始边缘不对齐时,若在固定帧长开始前做LBT,且检测到信道为空,则可以在实际传输之前再进行LBT,或者发送其他信号填充固定帧长边缘和上行传输资源之间的间隙(gap),或者基于网络设备的指示信息进行传输。
其中,终端基于网络设备的指示信息进行上行传输的情况下,网络设备在步骤101之前,还包括:在侦听到信道空闲的情况下,向终端发送指示信 息,指示信息用于指示:允许终端共享网络设备的固定帧长或者信道占用时长。具体地,网络设备在一个固定帧长开始之前做category 2的LBT,当检测到信道空闲时,网络设备指示终端可以共享(share)该固定帧长(fixed frame period)或信道占用时长(COT)进行传输。
本公开实施例的非授权频段的信息传输方法中,FEB网络设备可在非授权频段上进行信息传输。另外终端和网络设备各自对应独自的固定帧长,配置方式更加灵活,可降低资源浪费率,提高资源利用率。进一步地,网络设备还可采用与FEB信道接入机制一致的侦听类型进行信道侦听。
以上实施例分别详细介绍了不同场景下的非授权频段的信息传输方法,下面本实施例将结合附图对其对应的网络设备做进一步介绍。
如图11所示,本公开实施例的网络设备1100,能实现上述实施例中在第一传输信道上,接收上行信息;其中,第一传输信道采用第一固定帧长方法的细节,并达到相同的效果,该网络设备1100具体包括以下功能模块:
第三接收模块1110,用于在第一传输信道上,接收上行信息;其中,第一传输信道采用第一固定帧长。
其中,网络设备1100还包括:
第二侦听模块,用于对第二传输信道进行侦听;
第二发送模块,用于在侦听到信道空闲的情况下,在第二传输信道上发送下行信息;其中,第二传输信道采用第二固定帧长。
其中,第二固定帧长与第一固定帧长不同。
其中,网络设备1100还包括:
第三发送模块,用于向终端发送第一固定帧长和第二固定帧长中的至少一项。
其中,网络设备1100还包括:
第四接收模块,用于接收第一固定帧长。
其中,第三接收模块包括:
第一接收子模块,用于在第一传输信道中的上传输资源上,接收上行信息;其中,上行传输资源为配置授权传输资源或基于调度的传输资源。
其中,上行传输资源的时域起始位置与第一固定帧长的时域起始位置对 齐。
其中,上行传输资源的时域起始位置与第一固定帧长的时域起始位置未对齐。
其中,网络设备1100还包括:
第四发送模块,用于在侦听到信道空闲的情况下,向终端发送指示信息,指示信息用于指示:允许终端共享网络设备的固定帧长或者信道占用时长。
值得指出的是,本公开实施例的FEB网络设备可在非授权频段上进行信息传输。另外终端和网络设备各自对应独自的固定帧长,配置方式更加灵活,可降低资源浪费率,提高资源利用率。进一步地,网络设备还可采用与FEB信道接入机制一致的侦听类型进行信道侦听。
