下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前 后关联对象是一种“或”的关系。
非授权频段的信道接入
在非授权频段上在发送信息之前,终端或网络设备需要做信道空闲估计(Clear Channel Assess,CCA)/扩展信道空闲估计(extended Clear Channel Assess,eCCA)来侦听信道,即进行能量检测(Energy Detection,ED),当能量低于一定门限时,信道被判断为空,方可开始传输,即基于负载的设备(Load-Based Equipment,LBE)。由于非授权频段是多种技术或多个传输节点共享,因此这种基于竞争的接入方式导致信道可用时间的不确定性,当信道可用(available)时,网络侧信号传输的可传输位置可能已经错过而无法发送,这样可能导致接收端无法正常接收网络侧配置的信号接收,以及信号接收后根据网络侧的配置进行的终端行为,例如物理下行控制信道(Physical Downlink Control Channel,PDCCH)监听,对无线环境的监测和测量等。通过CCA的方式判断信道是否为空并进行传输的过程,可以称为信道接入过程。
目前明确可用于5G非授权通信系统的信道接入过程种类有以下三种:
Cat 1:不做任何CCA直接发送,必须是在已经获得信道的情况下在传输转换的间隔小于16us的情况下可以使用;
Cat 2(Type II):进行16us或者25us的信道侦听,对特定信号获取信道可以使用,最大连续传输长度应该小于一定数值,例如1ms;
Cat 4(Type I):进行随机回退的信道侦听,对不同优先级参数设置不同,最后获得信道后可传输的最大长度也不同。
同时,5GHz上的CCA频域粒度为20MHz,并且按照Regulation(规定)的信道规划严格执行。
基于帧的设备(Frame Based Equipment,FBE)网络操作
FBE是指设备的发送/接收定时采用周期结构,其周期为Fixed Frame Period。
FBE节点采用基于先听后说(Listen Before Talk,LBT)的信道接入机制占用信道。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)。FBE节点可以是发起节点,响应节点,或者同时支持两种节点功能。
其中,发起节点的操作示例参见图1,其操作要求包括:
节点支持的Fixed Frame Period取值集合由设备制造商声明,各取值要求都位于1~10ms范围内。仅可在某个Fixed Frame Period的开始时刻启动传输。节点可以更改其当前应用的Fixed Frame Period,但是其频度不能高于200ms一次。
在某个Fixed Frame Period的开始时刻启动传输之前,发起节点将执行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(监管要求规定的短控制信令传输(Short Control Signaling Transmissions)除外)。也就是说,发起节点在传输之前需要做one-shot LBT,即Cat.2LBT。
在某个已开始发送的Fixed Frame Period内,对应发起节点无需重新估计信道的可用性便可传输的总时长,定义为信道占用时间(Channel Occupancy Time,COT)。发起节点可以在COT内在指定信道上传输多次而无需执行额外的CCA,只要这些传输的相邻传输之间的时间间隔都不超过16μs。如果COT内相邻传输之间的时间间隔超过16μs,则发起节点在继续传输之前,需要执行额外的CCA,仅当CCA判断信道为空闲时继续传输。所有相邻传输之间的时间间隔都计入COT时长。
发起节点可以将COT内某些时段的指定信道的使用权授权给一到多个关联的响应节点进行传输。
COT不能长于Fixed Frame Period的95%,并且在COT后紧接着一个空闲时段(Idle Period),空闲时段持续至下一个Fixed Frame Period的开始时刻才结束,这样空闲时段的长度至少为Fixed Frame Period的5%,并且最小值为100μs。
某个节点在正确收到针对它的数据包之后,可以不作CCA直接立即在指定信道上传输数据包对应的管理和控制帧(例如ACK帧)。此节点需要保证这些连续传输的帧不能超出上述提到的最大COT时长。
响应节点在收到某个发起节点对指定信道在某些时段内的使用授权之后,将执行如下操作:
响应节点如果在发起节点指示授权的最后一次传输结束之后最多间隔 16μs后就发起传输,则其在传输之前无需执行CCA;否则在授权的传输时段开始之前执行CCA,如果判断信道为忙,则放弃此授权,否则,可在指定信道上启动传输,最多可占用当前Fixed Frame Period内COT的剩余部分,在剩余部分的时间范围内可启动多次传输,只要相邻传输的时间间隔不超过16μs即可,传输完毕后放弃此授权。
长期演进(Long Time Evolution,LTE)和NR系统都支持旁链路(Sidelink,或译为副链路,侧链路,边链路等)传输,如图2所示,为用户终端(User Equipment,UE)之间直接在物理层上进行数据传输。LTE sidelink是基于广播进行通讯的,虽然可用于支持车联网(vehicle to everything,V2X)的基本安全类通信,但不适用于其他更高级的V2X业务。5G NR(New Radio)系统将支持更加先进的sidelink传输设计,例如,单播,多播或组播等,从而可以支持更全面的业务类型。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,这些技术也可应用于NR系统应用以外的应用,如第6代(6
th Generation,6G)通信系统。
图3示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备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)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计 算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,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、发送接收点(Transmitting Receiving Point,TRP)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,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的免授权频谱的信道接入的方法进行详细地说明。
本申请实施例提供了一种免授权频谱的信道接入的方法,该方法应用于终端,图4是本申请实施例的免授权频谱的信道接入的方法流程图一,如图4所示,该方法的步骤包括:
步骤S402,终端执行第一事件,其中,第一事件为终端接收网络侧设备配置的免授权频谱的信道接入参数,或者第一事件为终端获取网络侧设备对免授权频谱的信道占用情况;
步骤S404,终端基于第一事件,进行免授权频谱的信道接入;
步骤S406,终端在免授权频谱的信道接入成功的情况下,发送旁链路SL信号和/或Uu信号。
通过上述步骤S402至步骤S406,在终端接收到网络侧设备配置的免授权频谱的信道接入参数,可以进行免授权频谱的信道接入,又或者终端通过获取网络侧设备的免授权频谱的信道占用情况,也可以进行免授权频谱的信道接入,进而发送SL信号和/或Uu信号,即实现了对免授权频谱的信道接入,增加了可用的频谱资源,从而解决了现有技术中授权频段越来越少,导致可用授权频段的灵活性受限的问题。
需要说明的是,对于本申请中终端获取网络侧设备对免授权频谱的信道占用情况的方式,在具体应用场景中,可以是网络侧设备向终端发送控制信息,该控制信息用于指示网络侧设备是否占用免授权频谱的信道;又或者是终端主动向网络侧设备发送监听消息,网络侧设备响应于监听消息反馈响应消息,该响应消息用于指示网络侧设备是否占用免授权频谱的信道。当然,上述方式仅仅是举例说明,此外,在具体应用场景中,可以根据实际情况采用不同的获取方式。
在本申请实施例的可选实施方式中,终端基于第一事件通过以下之一的方式进行免授权频谱的信道接入:负载的设备LBE方式、基于帧的设备FBE方式。
需要说明的是,不同的方式对应不同的信道接入参数,具体如下两种方式:
1)在基于LBE的方式进行信道接入的情况下,所需的参数为第一信道接入参数;可选地,该第一信道接入参数包括以下至少一项:信道空闲估计CCA时长、竞争窗口长度、信道占用长度、能量检测ED阈值。
2)在基于FBE的方式进行信道接入的情况下,所需的参数为第二信道接入参数;可选地,该第二信道接入参数包括以下至少一项:帧起始位置、帧的偏移量、帧周期长度、信道空闲估计CCA时长、信道占用长度、空闲周期长度、能量检测ED阈值。
也就是说,本申请实施例中涉及到的信道接入参数可以包括如下至少一项:第一信道接入参数、第二信道接入参数。
在本申请实施例的另一个可选实施方式中,对于第一事件中的接收网络侧设备配置的免授权频谱的信道接入参数,进一步可以是:接收网络侧设备根据终端的工作状态配置的免授权频谱的信道接入参数;其中,工作状态包括:在网工作状态、脱网工作状态;该根据工作状态配置的信道接入参数包括第一信道接入参数和/或第二信道接入参数。
也就是说,该根据工作状态配置的信道接入参数可以只包括第一信道接入参数中的部分或全部,也可以只包第二信道接入参数部分或全部,也可以是包括第一信道接入参数和第二信道接入参数中的部分或全部。在具体的应 用场景中,如果第一信道接入参数包括:信道空闲估计CCA时长、竞争窗口长度、信道占用长度,第二信道接入参数包括:帧起始位置、帧的偏移量、帧周期长度、信道空闲估计CCA时长、信道占用长度;则该根据工作状态配置的信道接入参数可以是只包括第一信道接入参数中的信道空闲估计CCA时长、竞争窗口长度,也可以是只包括第二信道接入参数中的帧起始位置、帧的偏移量、帧周期长度、信道空闲估计CCA时长。当然,这仅仅是举例说明,具体包括第一信道接入参数和/第二信道接入参数中的哪些参数可以根据实际的工作状态进行配置。也就是说,网络侧设备可以有针对性的为终端配置对应的信道接入参数,避免了资源的浪费。
在本申请实施例的另一个可选实施方式中,对于本申请实施例中的发送旁链路SL信号和/或Uu信号包括以下至少之一:
1)终端仅发送SL信号;
2)终端通过时分复用(Time Division Multiplexing,TDM)的方式发送SL信号和Uu信号。即可以是先发送SL信号后发送Uu信号,或者是先发送Uu信号后发送SL信号。
对于上述发送SL信号和/或Uu信号的方式,在具体应用场景中如图5所示,给出了FBE场景下,UE进行主动信道接入的示例,具体包括以下示例:
Case 1-1:UE接入信道后在frame period内仅发送SL信号;
Case 1-2:UE接入信道后在在frame period内先发送SL信号,再发送Uu UL信号;
Case 1-3:UE接入信道后在在frame period内先发送Uu UL信号,再发送SL信号。
上述Case 1-2和Case 1-3为通过时分复用TDM的方式发送SL信号和Uu信号的两种情况。需要说明的是,上述不同示例下的ED threshold不同,此外,图5中虽然仅给出FBE信道接入场景的示例,但UE进行主动信道接入的示例也适用于LBE信道接入场景。
在本申请实施例的另一个可选实施方式中,在免授权频谱的信道接入成功的情况下,本申请实施例的方法还包括:
步骤S408,终端获取信道占用时间COT;
步骤S410,终端向网络侧设备或者其他终端共享COT。
对于上述步骤S410中涉及到的向网络侧设备共享COT的方式,在具体应用场景中,如图6所示,给出了FBE场景下,UE进行主动信道接入,并将COT共享给gNB的示例,具体示例如下:
Case 2-1:UE接入信道后,发送Uu UL和SL信号,并将COT共享给gNB;
Case 2-2:UE接入信道后,发送SL和Uu UL信号,并将COT共享给gNB。
需要说明的是,上述不同示例下的ED threshold不同,此外,图6中虽然仅给出FBE channel access场景的示例,但UE进行主动信道接入,并将COT共享给gNB的示例也适用于LBE场景。
当然,上述其他终端也可以接收终端共享的COT。
对于上述步骤S210中涉及到的向其他终端共享COT的方式,在具体应用场景中,如图7所示,具体示例如下:
Case 3-1:UE1接入信道后,发送SL信号,并将COT共享给UE2;
Case 3-2:UE1接入信道后,发送SL信号和Uu信号,并将COT共享给UE2;
需要说明的,上述不同示例下的ED threshold不同。
在本申请实施例的另一个可选实施方式中,在免授权频谱的信道接入成功的情况下,本申请实施例的方法还包括以下至少之一:
1)在终端在多个载波或多个LBT子带成功接入免授权频谱的信道的情况下,向网络侧设备发送第一控制信息;其中,其中,第一控制信息可以用于指示以下至少一项:共享给所述网络侧设备的载波数量、共享给所述网络侧设备的载波编号、共享给所述网络侧设备的LBT子带数量、共享给所述网络侧设备的LBT子带编号;
其中,该方式在具体应用场景中,如图8所示,UE在多个CC或者LBT-BW上进行主动信道接入,并发送Uu UL和/或SL信号,UE通过发送上行控制信息告知gNB将部分或全部CC或者LBT-BW共享给gNB;其中,上行控制信息指示可以共享给gNB的CC或者LBT-BW的数量和/或编号;具体实施例如下:
Case 4-1:UE在两个LBT-BW上同时接入信道后,发送Uu UL和SL信号,并通过上行控制信息告知gNB两个LBT-BW都共享给gNB;
Case 4-2:UE在两个LBT-BW上同时接入信道后,发送Uu UL和SL信号,并通过上行控制信息告知gNB其中一个LBT-BW共享给gNB。
需要说明的是,上述不同示例下的ED threshold不同。
2)在终端在多个载波或多个LBT子带成功接入信道的情况下,向其他终端发送第二控制信息;其中,其中,第二控制信息可以用于指示以下至少一项:共享给所述网络侧设备的载波数量、共享给所述网络侧设备的载波编号、共享给所述网络侧设备的LBT子带数量、共享给所述网络侧设备的LBT子带编号。
当然,上述其他终端也可以接收终端发送的第二控制信息。
其中,该方式在具体应用场景中,如图9所示,UE1在多个CC或者LBT-BW上进行主动信道接入,并发送Uu UL和/或SL信号,UE1通过发送SL发送控制信息告知UE2将部分或全部CC或者LBT-BW共享给UE2;其中,SL控制信息指示可以共享给UE2的CC或者LBT-BW的数量和/或编号,具体示例如下:
Case 5-1:UE1在两个LBT-BW上同时接入信道后,发送Uu UL和SL信号,并通过SL控制信息告知UE2两个LBT-BW都共享给UE2;
Case 5-2:UE1在两个LBT-BW上同时接入信道后,发送Uu UL和SL信号,并通过SL控制信息告知UE2其中一个LBT-BW共享给UE2。
需要说明的是,上述不同示例下的ED threshold不同。
在本申请实施例的可选实施方式中,本申请实施例中的可发送的信息和/或共享方式由网络侧设备配置;其中,可发送的信息包括以下至少一项:SL信号、Uu信号、第一控制信息、第二控制信息;共享方式包括以下至少一项:不允许共享COT、向网络侧设备共享COT的方式、向其他终端共享COT的方式。
也就是说,对于终端是否仅发送SL信号,或者是通过TDM的方式发送SL信号和Uu信号,以及是否发送第一控制信息和第二控制信息均可以是由网络侧设备配置的。例如,虽然终端可以仅发送SL信号,或通过TDM的方 式发送SL信号和Uu信号,但是该发送的过程由网络侧设备配置,即如果网络侧仅配置了SL信号,则终端只需要发送SL信号,如果网络侧设备配置了SL信号和Uu信号,则终端可以通过TDM方式发送SL信号和Uu信号。对于第一控制信息和第二控制信息也是同样的处理方式。
此外,对于共享方式也是类似的,即如果网络侧设备只配置了向所述网络侧设备共享COT的方式,则终端只执行向网络侧设备共享COT的方式,而不会向其他终端共享COT。当然,如果网络侧设备配置的是不共享COT,则终端不执行共享操作。
需要说明的是,本申请实施例中的涉及到的不同信息的发送过程可以对应不同的ED阈值;也就是说,如果网络侧配置终端可以发送信号或信息,则每次发送信号或信息的发送过程可以是对应不同的ED阈值;该ED阈值也可以由网络侧配置,也可以由终端自主进行确定。
在由网络侧设备配置的情况下,就是直接通知终端可发送的信息包括的不同信息的发送过程对应不同的ED阈值,以及不同的共享方式对应不同的ED阈值;其中,可发送的信息包括以下至少一项:SL信号、Uu信号、第一控制信息、第二控制信息;共享方式包括以下至少一项:不允许共享COT、向网络侧设备共享COT的方式、向其他终端共享COT的方式。
在由终端自主确定ED阈值的情况下,需要终端向网络侧设备发送指示信息,其中,指示信息用于指示终端当前所使用的ED阈值和/或所使用的共享方式的;其中,共享方式包括以下至少一项:不允许共享COT、向网络侧设备共享COT的方式、向其他终端共享COT的方式。
上述是从终端侧对本申请中的信道接入过程进行描述,下述将从网络侧对本申请中的信道接入过程进行描述。
在本申请中还提供了一种信道接入的方法,该方法应用于网络侧设备,图10是本申请实施例的信道接入的方法流程图二,如图10所示,该方法的步骤包括:
步骤S1002,发起免授权频谱的信道接入或为终端配置免授权频谱的信道接入参数。
可见,对于网络侧设备而言,可以为终端配置信道接入参数,也可以不 用为终端配置信道接入参数,直接发起信道接入流程,由终端自行获取网络侧设备的信道占用情况。通过这两种方式,终端均是可以进行免授权频谱的信道接入。
进一步地,在发起信道接入情况下,方法还包括以下至少之一:
1)在发起免授权频谱的信道接入成功后,将第一COT共享给终端;其中,第一COT用于终端发送SL信号;
2)在发起免授权频谱的信道接入成功后,将第二COT共享给终端;其中,第二COT用于终端发送SL信号和Uu信号。
也就是说,网络侧设备在信道接入成功后可以为终端共享不同的COT,以用于终端发送不同的信号。对于上述方式1)和2)在具体应用场景中,如图11所示,给出FBE场景下,gNB进行主动信道接入,并将COT共享给UE的示例,具体如下示例:
Case 6-1:gNB接入信道后,将COT共享给UE用于SL信号发送;
Case 6-2:gNB接入信道后,将COT共享给UE用于先发送SL信号且后发送Uu UL信号;
Case 6-3:gNB接入信道后,将COT共享给UE用于先发送Uu UL信号且后发送SL信号。
需要说明的是,上述不同case下的ED threshold不同,此外,图11中虽然仅给出FBE channel access场景的示例,但gNB进行主动信道接入,并将COT共享给UE的示例也适用于LBE场景。
需要说明的是,不同的共享方式对应不同的ED阈值;其中,共享方式包括:向终端共享第一COT的方式、向终端共享第二COT的方式。
此外,在网络侧设备未主动发起免授权频谱的信道接入的情况下,网络侧设备可以接收终端发送的第一控制信息;其中,第一控制信息为终端在多个载波或多个LBT子带成功接入信道后向网络侧设备发送的;第一控制信息用于指示共享给网络侧设备的载波或LBT子带的数量和/或载波或LBT子带的编号。
在本申请实施例中,本申请实施例的方法还可以包括:
步骤S1004,网络侧设备为终端配置可发送的信息和/或共享方式;
其中,可发送的信息包括以下至少一项:SL信号、Uu信号;
共享方式包括以下至少一项:不允许共享COT、向终端共享第一COT的方式、向终端共享第二COT的方式。
需要说明的是,本申请实施例的方法步骤还可以包括:
步骤S1006,网络侧设备还可以配置可发送的信息包括的不同信息的发送过程对应不同的ED阈值,以及不同的共享方式对应不同的ED阈值;
步骤S1008,网络侧设备向终端发送第二指示信息;

在本申请实施例中,对于步骤S1002中涉及到的为终端配置信道接入参数的方式,进一步可以包括:为终端配置第一信道接入参数和/或第二信道接入参数;其中,第一信道接入参数为终端通过基于负载的设备LBE的方式进行SL信道接入所需的参数;第二信道接入参数为终端通过基于帧的设备FBE的方式进行SL信道接入所需的参数。
其中,第一信道接入参数包括以下至少一项:信道空闲估计CCA时长、竞争窗口长度、信道占用长度、能量检测ED阈值;
第二信道接入参数包括以下至少一项:帧起始位置、帧的偏移量、帧周期长度、信道空闲估计CCA时长、信道占用长度、空闲周期长度、能量检测ED阈值。
进一步地,对于上述步骤S1002中涉及到的为终端配置信道接入参数还可以进一步是:配置与终端的工作状态对应的第三信道接入参数;其中,工作状态包括:在网工作状态、脱网工作状态;信道接入参数包括第一信道接入参数和/或第二信道接入参数。
需要说明的是,本申请实施例提供的免授权频谱的信道接入方法,执行主体可以为免授权频谱的信道接入装置,或者,该免授权频谱的信道接入装置中的用于执行免授权频谱的信道接入方法的控制模块。本申请实施例中以免授权频谱的信道接入装置执行免授权频谱的信道接入方法为例,说明本申 请实施例提供的免授权频谱的信道接入方法装置。
