为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
无线通信是建立在频谱的基础上,而频谱通常和划分为授权频谱和免授权频谱两大类,其中授权频谱被广泛用于移动通信、卫星通信、雷达探测等应用场景,且其使用需要得到监管部门的授权才可以使用;而免授权频谱则是与之相对的另外一种使用方式,也即在免授权频谱上面无需监管部门的授权即可使用这段频谱,比如通常所用到的WiFi、蓝牙等都是工作在免授权频谱上面。目前免授权频谱包括了频率比较低的频谱如2.4GHz、5GHz等,也包括了频率高达几十GHz的毫米波频谱。
对于免授权频谱资源来说,所有终端都可以使用,如果不加控制就会导致多个终端同时占用相同的频谱资源发射信号或接收信号导致信号间产生相互干扰,甚至无法被接收端接收。因此,免授权频谱资源的使用通常会采用抢占的方式进行频谱资源的使用,即终端在发射信号之前,需要监测计划使用的频谱资源上面是否有其它终端在发射和/或接收信号(即计划使用频谱资源是否被其它终端占用),如果有则不能接入,如没有其它终端在发射和/或接收信号,终端可以尝试发起接入该频谱(即使用/占用该频谱资源)。然而,当终端尝试发起接入该频谱的情况下,存在另外一个终端也在尝试发起接入该频谱,那么就会造成这两个终端间的接入频谱冲突,此时终端需要回退一个随机时间长度来规避冲突,并再次监测是否有其它终端占用目标频谱资源。
在本申请任一实施例中,占用/使用目标频谱资源、占用/使用目标频谱、占用/使用目标频段资源、占用/使用目标频段、接入目标频谱以及接入目标频谱资源可以作同一理解。在本申请任一实施例中,目标频谱资源或目标频段资源可以为本申请实施例中的第一频域资源。
图1为相关技术提供的一种终端占用免授权频谱资源的方式示意图,如图1所示,在t1时刻终端1尝试接入目标频谱,例如终端1在t1时刻监测目标频谱或目标频段(监测方式为测量该目标频谱的以下之一:功率强度、频谱强度、信号强度,当测量值大于第一阈值时则认为该目标频谱上有其它终端在该发射/使用),终端1发现有其它终端占用该频谱(即目标频谱被其它终端),则终端回退一个随机时间长度T1(回退时间T1),这样在T1时长后的t2时刻终端1开始继续监测是否有其它终端使用该目标频谱。
在t2时刻终端1尝试接入目标频谱,例如终端1在t2时刻监测到当前没有终端占用该目标频谱,于是尝试接入该目标频谱,但同时终端2也在尝试接入该目标频谱,于是造成了尝试接入的碰撞。可选地,在一些实施例中,终端1在目标频谱接收到终端2发送的信息,表明终端1和终端2的接入发生碰撞。可选地,在另一些实施例中,终端1在t2时刻监测目标频谱或目标频段的以下之一:功率强度、频谱强度、信号强度,当测量值大于第二阈值时则认为终端1和终端2的接入发生碰撞。可选地,第二阈值大于第一阈值。可选地,第二阈值可以大于终端1的信号发射功率强度。可选地,功率强度可以理解为功率值。
在终端1和终端2的接入发生碰撞的情况下,终端1可以回退一个随机时间长度T2(回退时间T2),这样在T2时长后的t3时刻终端1开始继续监测是否有其它终端使用该目标频谱。
在终端1和终端2的接入发生碰撞的情况下,终端2可以回退一个随机时间长度T3(回退时间T3),这样在T3时长后的t4时刻终端2开始继续监测是否有其它终端使用该目标频谱。
终端1在t3时刻监测到没有其它终端占用该目标频谱资源,尝试接入成功,占用该目标频谱资源,这样,终端1接入成功。
终端2在t4时刻监测到没有其它终端占用该目标频谱资源,尝试接入成功,占用该目标频谱资源,这样,终端2接入成功。
在本申请任一实施例中,目标频谱可以与目标频谱资源对应,终端接入目标频谱、终端接入目标频谱资源、终端占用/使用目标频谱、终端占用/使用目标频谱资源可以作同一理解。
在相关技术中,当前的终端接入免授权频谱的方式是一种类似“碰运气”的接入方式,也即在当没有其它终端占用时才可以接入,当有其它终端占用或有发生接入频谱冲突等终端需要回退一个随机时间长度,并再次“碰运气”去监测频谱并在空闲时尝试接入,直到成功接入目标频谱。
在这种方式中,终端无法预期目标频谱在什么时间点是空闲的,以及在什么时间点能够成功接入该频谱,这造成了终端需要不断地监测目标频谱的使用情况造成终端的功耗较高。此外,无法预期的频谱使用也造成了终端业务连续性和业务的时延难以保证的问题。换句话说,由于相关技术中免授权频谱的使用方式采用抢占的模式导致终端无法预知频谱的使用情况,只能采取不断监测频谱的占用情况以及不断尝试接入的方式。当终端数量比较多时,发生接入冲突的可能性变大,终端的业务时延增加,性能难以保证。

以下以另一种方式说明本申请通信方法的实施例,需要说明的是,上述的第一终端或第二终端可以为下述列举的任一个终端:
在一些实施例中,一种解决当前免授权频谱“碰运气”式接入带来问题的方式,是采用基于优先级的排队工作方式。终端基于“先到先得”的原则,发起接入需求越早的终端具有越高的接入优先级,发起接入需求越晚则优先级越低。终端按照优先级依次接入并占用该频谱,从而使得频谱的使用具有可预见性,避免无序碰撞带来的时延等问题。
在一些实施例中,终端的接入优先级按照发起接入的需求(即发送第一请求)时间先后来确定,时间越早则接入优先级越高。
在一些实施例中,对于部分紧急业务场景,比如紧急呼叫等,定义插队模式,在该模式下终端的接入优先级将被提高。举例而言,当前有终端1在占用频谱资源,终端2和终端3在按照优先级高低排队,终端4此时有紧急业务需要快速接入频谱,那么可以有下述两种操作方式:
方式A:终端4的接入优先级提高到所有排队终端的前面,等终端1完成业务不再占用该频谱后,终端4接入该频谱;
方式B:终端4直接抢占频谱进行紧急业务,此时终端1将临时释放该频谱,并在排队系列的最高优先级。当终端4完成紧急业务释放频谱后,终端1将继续开展其此前中断的业务。
在一些实施例中,上述终端的插队模式仅适用于紧急业务场景,当终端通过插队模式抢占频谱后,其进行的业务也需是紧急业务。可选地,如开展的业务并非紧急业务,那么在后续的频谱接入中该终端的接入优先级将被降低。
在一些实施例中,终端的插队模式可以在提出接入申请(对应上述的第一请求)时携带一个紧急业务指示信息(对应上述的预定业务指示信息),同时可以携带紧急业务的时长信息。但需要注意的是终端提出插队模式并不一定意味着该终端一定能够优先抢占成功,比如同时有多个终端提出紧急业务需求等。
在一些实施例中,可以定义频谱预定信息(例如,上述的第一信息或第二信息)广播时间点,比如以10ms为间隔的一系列时间节点,在这些时间节点上终端收听当前频谱的占用情况以及终端排队情况信息,可以预测出能够接入频谱的时间点。
图4为本申请实施例提供的一种频谱预定信息的广播时刻示意图,如图4所示,目标频谱的广播时刻包括时间t1、时间t2以及时间t3等。
在一些实施例中,可以定义终端接入时间长度单位TU(对应上述的时间单元),终端申请占用频谱的时间长度需要是TU的整数倍。可选地,目标频谱的广播时刻可以跟TU的起始或截止时间对齐。可选地,接入时间节点(占用目标频谱资源的时间点)可以与TU的某个位置对齐,比如与TU的中心对齐,又比如接入时间节点也可以与TU的起始或截止时间对齐。
图5为本申请实施例提供的一种TU与广播时刻的关系示意图,如图5所示,目标频谱的广播时刻包括时间t1、时间t2以及时间t3等,相邻两次目标频谱的广播时刻的间隔可以为2TU。在一些实施例中,为了避免终端一旦抢占成功就会一直占用频谱,导致其它终端无法使用该频谱的情况,定义一个最长频谱占用时间Tmax(对应上述的第二预定时长)。当终端抢占成功后,其单次占用该频谱的时间长度不能超过Tmax。图5示出了Tmax的长度为5TU,但是本申请实施例不限于此,Tmax的长度可以为其它,例如,Tmax的长度可以为其它的一个或多个TU,示例性地,Tmax的长度可以为2TU、10TU或50TU等等。
终端接入目标频谱的行为需要考虑当前有终端占用频谱的场景,和当前没有终端占用频谱的场景。
在当有终端占用频谱时,占用频谱的终端作为这个频谱的核心终端(对应上述的第一终端或第三终端),将会收集提出接入请求(对应上述的第一请求)的所有终端信息,包括预期占用时间长度、接入优先级等,并将这些终端接入申请信息(对应的上述的ID一信息或第二信息)在广播时刻进行广播。
可选地,在实施过程中,终端可以在任意时间提出接入请求:该接入请求信息(时间长度)可以是以广播的方式发起,或者,可以是仅向核心终端发起。
可选地,核心终端收到终端的接入请求后,按照时间到达的先后顺序进行优先级排序,得到一个频谱预定信息表(频谱预定信息可以包括在上述的第一信息中),包括先后接入的终端及其对应的时间长度。
可选地,核心终端广播的当前频谱接入信息可以包括以下至少之一:当前已预定的时间窗口信息、当前可用的时间窗口信息、当前终端的优先级排序及预定时间长度信息。
可选地,终端在广播时刻收听当前频谱的接入信息。
图6为本申请实施例提供的一种终端占用目标频谱的示意图,如图6所示,终端占用目标频谱的过程如下:
在t1时刻之前终端1作为占用频谱的核心终端收到来自终端2(作为请求接入终端)的接入请求(对应上述的第一请求,接入请求包括占用目标频谱的时长为1TU),于是作为核心终端的终端1在广播时刻t1时刻广播当前接入信息(即广播接入信息)包括终端1在后续时刻中将占用3TU,然后终端2将占用1TU,其中,终端1占用的3TU和终端2占用的1TU是根据优先级从高到低的顺序排列的。
在广播时刻t2时刻作为核心终端的终端1广播当前的接入信息(即广播接入信息)包括终端1在后续时刻中将占用1TU,然后终端2将占用1TU。其中,终端1占用的1TU和终端2占用的1TU是根据优先级从高到低的顺序排列的。
在广播时刻t2间隔1TU的时刻,终端1占用目标频谱结束,终端2开始占用目标频谱,在t3时刻,终端2占用目标频谱结束。
在一些实施例中,如在同一时刻有两个终端提出接入请求,那么处理方式可以是由核心终端自主确定冲突终端的优先级顺序,或者基于一定规则确定,比如预定时间长的终端优先级更低等。
图7为本申请实施例提供的另一种终端占用目标频谱的示意图,图7与图6的区别在于:图7对应的实施例中还具有以下方案:在广播时刻t3时刻,由于没有终端占用目标频谱,因此广播时刻t3时刻无广播消息发出,如果终端3需要占用目标频谱,终端3可以监听目标频谱没有被占用,终端3占用该目标频谱,之后终端3将作为核心终端可以接受其它终端发送的接入请求。这样,在t3时刻由于没有终端在排序,将没有接入信息广播,终端3随后尝试进行接入,如接入成功将成为新的核心终端。如接入不成功(存在同时接入的冲突终端)则采用现有技术回退一个随机时间长度再次尝试接入,直到有终端接入成功成为核心终端。
在一些实施例中,对于周期性业务,可以允许终端一次性申请多个周期性接入窗口,或者说通过第一请求来请求多个周期性接入窗口。
在一些实施例中,对于传输时间很长且对时延要求较高的业务,可以允许终端一次性申请多个连续接入时间窗口。
在一些实施例中,对于上述多个连续或周期性时间窗口的接入优先级可以根据申请时刻的优先级确定,也可以采取时间窗口优先级逐步降低的方式。
图8为本申请实施例提供的一种占用周期性接入窗口的示意图,如图8所示,终端可以在每4个TU占用2个TU的目标频谱。示例性地,一个终端可以占用窗口1、窗口2以及窗口3对应的目标频谱。
本申请实施例中,通过在目标免授权频谱(对应上述的第一频域资源或目标频谱)上通过频谱占用预定信息(对应上述的第一信息)广播,可以减少终端盲目的频谱占用情况检测,且随着频谱占用预定信息的周期性广播,终端可以实时知道当前以及后续的频谱占用情况,这样可以使得无序的免授权频谱的使用变得更加透明且可预期。
