Description

终端模式获取方法、装置及设备 技术领域
本申请涉及通信领域,尤其涉及一种终端模式获取方法、装置及设备。
背景技术
目前,在车辆到外界任意设备(vehicle to X,简称V2X)领域所涉及的终端可以包括车辆、车载设备、手持设备等(下文统称终端设备)。
在终端设备进行通信的过程中,终端设备之间传输的数据无需基站进行中转。在终端设备进行通信之前,基站为终端设备分配资源池,或者,为终端设备预先配置有资源池,以使终端设备在通信过程中可以使用资源池中的资源。目前,终端设备包括模式3和模式4两种模式,当终端设备为模式3时,终端设备在通信过程中所使用的资源为基站在资源池中为终端设备选取的。当终端设备为模式4时,终端设备在通信过程中所使用的资源为终端设备在资源池中选取的。
然而,当模式3的终端设备和模式4的终端设备共用同一资源池时,由于无法获取得到时频资源被哪种终端模式的终端使用,导致模式3的终端设备和模式4的终端设备共用同一资源池会出现较大干扰。
发明内容
本申请提供一种终端模式获取方法、装置及设备,可以获取得到终端设备在时频资源上发送数据时的终端模式。
第一方面,本申请提供一种终端模式获取方法,该方法的执行主体为第一终端设备,第一终端设备可以使用共享资源池,共享资源池被至少两种终端模式的终端设备共用。第一终端设备可以获取得到能够使用共享资源池的终端设备的至少两种终端信息,终端信息包括终端模式和终端类型;在第一终端设备接收到第二终端设备发送的控制信息之后,第一终端设备可以根据控制信息、及终端信息,确定第二终端设备在第一时频资源上发送数据时的终端模式,其中,控制信息用于指示第二终端设备在共享资源池的第一时段内的第一时频资源上发送数据。
在本申请中,在配置共享资源池时,配置了能够使用该共享资源池的终端设备的至少两种终端信息,当第二终端设备需要在共享资源池中的第一时频资源上发送数据时,第二终端设备发送控制信息,相应的,在第一终端设备接收到第二终端设备发送的控制信息之后,可以根据至少两种终端信息和控制信息确定得到第二终端设备在第一时频资源上发送数据时的终端模式。
可选的,第一终端类型为R.14终端类型,第二终端类型为R.15终端类型;第一终端模式为模式3,第二终端模式为模式4。
可选的,当第二终端设备的终端类型为第二终端类型时,控制信息中包括第二终 端设备的终端模式或终端类型。
可选的,终端信息为基站广播、或者通过无线资源控制RRC专用信令发送的;或者,终端信息为在第一终端设备中预先配置的。
可先的,第一终端设备可以通过至少如下两种可行的实现方式:
一种可行的实现方式:
若控制信息中包括终端模式,则第一终端设备将控制信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式。
若控制信息中不包括终端模式,则第一终端设备在至少两种终端信息中确定第一终端信息,并将第一终端信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式,第一终端信息中的终端类型为第一终端类型。
该种可行的实现方式适用于所有的应用场景。例如,当至少两种终端信息包括:
R.14mode3和R.15mode4,或者,
R.14mode4和R.15mode3,或者,
R.14mode3、R.15mode3和R.15mode4,或者
R.14mode4、R.15mode3和R.15mode4时,第一终端设备均可以通过上述可行的实现方式确定第二终端设备在第一时频资源上发送数据时的终端模式。
另一种可行的实现方式:
若控制信息中包括终端类型,则第一终端设备根据控制信息中包括终端类型,在至少两种终端信息中确定第二终端信息,并将第二终端信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式,第二终端信息中的终端类型为第二终端类型。
若控制信息中不包括终端类型,则在至少两种终端信息中确定第一终端信息,并将第一终端信息中包括的终端类型确定为第二终端设备在第一时频资源上发送数据时的终端类型,第一终端信息中的终端类型为第一终端类型。
在该种可行的实现方式适用于部分应用场景,即,至少两种终端信息中每两种终端信息的终端模式均不同、且每两种终端信息的终端类型均不同,相应的,至少两种终端信息的个数为两种。例如,该两种终端信息包括R.14mode3和R.15mode4,或者,至少两种终端信息包括:R.14mode4和R.15mode3。
在上述任意一个方法的基础上,当第一终端设备的终端类型为第二终端类型,第一终端设备的终端模式为第二终端模式(第一终端设备的设备信息为R.15mode4),第一时频资源的个数为至少一个,相应的,在确定得到至少一个第二终端设备在至少一个第一时频资源上发送数据时的终端模式之后,第一终端设备还可以在第二时段内的时频资源中选择备选时频资源。即,第一终端设备根据至少一个第一时频资源对应的信号强度和第二终端设备在至少一个第一时频资源发送数据时的终端模式,在共享资源池的第二时段内的时频资源中确定备选时频资源。
可选的,第一终端设备可以通过至少如下两种可行的实现方式在第二时段的时频资源中确定备选时频资源:
一种可行的实现方式:第一终端设备根据第二终端设备在至少一个第一时频资源上发送数据时的终端模式,在至少一个第一时频资源中确定第二时频资源和第三时频 资源,在第二时频资源上发送数据的终端设备的终端模式为第一终端模式,在第三时频资源上发送数据的终端设备的终端模式为第二终端模式;第一终端设备根据第二时频资源对应的时域时间间隔、第三时频资源对应的时域时间间隔、及第三时频资源对应的信号强度,在第二时段内的时频资源中确定备选时频资源。
可选的,第一终端设备根据第二时频资源对应的时域时间间隔,在第二时段内的时频资源中确定第五时频资源,第五时频资源对应的终端模式与在第二时频资源上发送数据的终端设备的终端模式相同;第一终端设备根据第三时频资源对应的时域时间间隔,在第二时段内的时频资源中确定第六时频资源,第六时频资源对应的终端模式与在第三时频资源上发送数据的终端设备的终端模式相同,第六时频资源的信号强度与第三时频资源的信号强度相同;第一终端设备根据第五时频资源、及第六时频资源的信号强度,在第二时段内的时频资源中确定备选时频资源。
可选的,第一终端设备将第二时段内的时频资源中除第五时频资源外的时频资源确定为初级备选时频资源;第一终端设备根据第六时频资源的信号强度,在初级备选时频资源中确定备选时频资源。
在该种可行的实现方式中,在第一终端设备确定得到的第五时频资源在未来可能被第一终端模式的终端设备使用,由于第一终端模式的终端设备在收发数据时对其它终端设备的干扰要求较为严格,因此,第一终端设备将第五时频资源排除在备选时频资源之外,可以保证第一终端设备一定不在第五时频资源上发送数据,进而可以避免第一终端设备对可能在第五时频资源上发送数据的第一终端模式的终端设备造成干扰。进一步的,确定得到的第六时频资源在未来可能被第二终端模式的终端设备使用,当第一终端设备估计的第六时频资源的信号强度大于预设阈值时,则说明未来在第六时频资源上发送数据的终端设备的功率过大、或者与第一终端设备的距离过近,因此,第一终端设备将第六时频资源中信号强度大于预设阈值的时频资源排除在备选时频资源之外,可以避免第一终端设备与在信号强度大于预设阈值的第六时频资源上发送数据的终端设备之间相互干扰。由上可知,第一终端设备通过估计第二时段内的时频资源对应的终端模式,可以准确的在第二时段的时频资源中选择备选时频资源。
另一种可行的实现方式:
第一终端设备根据第二终端设备在至少一个第一时频资源上发送数据时的终端模式、以及至少一个第一时频资源对应的时域时间间隔,确定第二时段内的时频资源中至少一个第四时频资源的对应的终端模式;第一终端设备根据至少一个第一时频资源对应的信号强度、以及至少一个第一时频资源对应的时域时间间隔,确定至少一个第四时频资源的信号强度;第一终端设备根据至少一个第四时频资源对应的终端模式和至少一个第四时频资源对应的信号强度,在第二时段内的时频资源中确定备选时频资源。
可选的,第一终端设备根据至少一个第四时频资源对应的终端模式,在至少一个第四时频资源中确定第五时频资源和第六时频资源,第五时频资源对应的终端模式为第一终端模式,第六时频资源对应的终端模式为第二终端模式;第一终端设备根据第五时频资源对应的信号强度、第一终端模式对应的第一阈值、第六时频资源对应的信号强度、及第二终端模式对应的第二阈值,在第二时段内的时频资源中确定备选时频 资源。
在该种可行的实现方式中,第一终端设备先在第二时段内的时频资源中确定至少一个第四时频资源,并获取每一个第四时频资源对应的终端模式和信号强度。不同的终端模式对应不同的阈值,第一终端设备根据第四时频资源对应的终端模式,在至少一个第四时频资源中确定第五时频资源和第六时频资源,并根据第五时频资源对应的信号强度、第一终端模式对应的第一阈值、第六时频资源对应的信号强度、及第二终端模式对应的第二阈值,在第二时段内的时频资源中确定备选时频资源。由于第一终端模式的终端设备对其它终端设备的干扰要求与第二终端模式的终端设备对其它终端设备的干扰要求不同,因此,通过上述方法可以准确的在第二时段的时频资源中选择备选时频资源。
在上述任意一个方法的基础上,当第一终端设备的终端类型为第二终端类型,第一终端设备的终端模式为第一终端模式(第一终端设备的设备信息为R.15mode3),第一时频资源的个数为至少一个,相应的,在确定得到至少一个第二终端设备在至少一个第一时频资源上发送数据时的终端模式之后,第一终端设备还可以执行如下操作:
第一终端设备根据第二终端设备在至少一个第一时频资源上发送数据时的终端模式、及至少一个第一时频资源对应的时域时间间隔,在共享资源池的第二时段内的时频资源中确定第六时域资源,第六时域资源的终端模式为第二终端模式;第一终端设备获取第六时频资源的属性信息,并向基站发送第六时频资源的属性信息;属性信息至少包括第六时频资源在共享资源池中的位置,或者,属性信息至少包括第六时频资源在共享资源池中的位置和第六时频资源的信号强度。
在上述过程中,在基站接收到第六时频资源的属性信息之后,当基站在第二时频资源中为终端设备分配时频资源时,先将第六时频资源剔除在备选时频资源之外,再在备选时频资源中为终端设备分配时频资源,这样,可以避免第二终端模式的终端设备对第一终端模式的终端设备造成干扰。
第二方面,本申请提供一种终端模式获取方法,该方法包括:第二终端设备确定控制信息,控制信息包括第二终端设备的终端模式或终端类型,第二终端设备的终端类型为第二终端类型,第二终端设备向第一终端设备发送控制信息。
在上述过程中,在第二终端设备向第一终端设备发送控制信息之后,可以使得第一终端设备根据该控制信息和至少两种终端信息确定得到第二终端设备在第一时频资源上发送数据时的终端模式。
第三方面,本申请提供一种终端模式获取方法,该方法包括:基站确定共享资源池的至少两种终端信息,共享资源池被至少两种终端模式的终端设备共用,至少两种终端信息为能够使用共享资源池的终端设备的终端信息,终端信息包括终端模式和终端类型;基站向第一终端设备发送至少两种终端信息。
在上述过程中,在基站向第一终端设备发送至少两种终端信息之后,可以使得第一终端设备根据该至少两种终端信息和控制信息确定得到第二终端设备在第一时频资源上发送数据时的终端模式。
可选的,基站还可以接收到第一终端设备发送的第六时频资源的属性信息,属性信息至少包括第六时频资源在共享资源池中的位置,或者,属性信息至少包括第六时 频资源在共享资源池中的位置和第六时频资源的信号强度;基站根据第六时频资源的属性信息,确定备选时频资源。
可选的,当属性信息中包括第六时频资源在共享资源池中的位置时,基站可以根据第六时频资源在共享资源池中的位置,将共享资源池中、除第六时频资源外的时频资源确定为备选时频资源。
可选的,当属性信息中包括第六时频资源在共享资源池中的位置和第六时频资源的信号强度时,基站可以根据第六时频资源在共享资源池中的位置和信号强度,将共享资源池中、除信号强度大于预设阈值的第六时频资源外的时频资源确定为备选时频资源。
在上述过程中,基站可以更加准确的为终端设备确定时频资源,以减小终端设备之间的干扰。

在终端设备发送控制信息和数据时,均需要使用资源池中的时频资源。目前,终端设备可以通过两种模式使用资源池中的资源,一种为模式3,一种为模式4。当终端设备通过模式3使用资源池中的资源时,由基站在资源池中当前时刻之后的时频资源中为终端分配时频资源。当终端设备通过模式4使用资源池中的资源时,由终端设备根据资源池中当前时刻之前的时频资源的占用情况,对资源池中当前时刻之后的时频资源进行估计,并在当前时刻之后的时频资源中选择时频资源。
在现有技术中,由于模式3的终端设备使用的时频资源由基站分配,模式4的终端设备使用的时频资源由终端设备选择,且模式3的终端设备在收发数据时对其它终端设备的干扰要求,比模式4的终端设备在收发数据时对其它终端设备的干扰要求严格。因此,为了避免模式3的终端设备和模式4的终端设备在收发数据时相互干扰,模式3的终端设备和模式4的终端设备不共用相同的资源池。
在本申请中,为了提高资源池的资源利用率,资源池可以被模式3的终端设备和模式4的终端设备共用。同时,为了避免模式3的终端设备和模式4的终端设备在收发数据时相互干扰,在模式4的终端设备选择需要使用的时频资源时,或者模式3的终端设备请求基站分配时频资源时,终端设备可以通过本申请所示的方法获取使用当前时刻之前的时频资源的终端设备的终端模式(模式3或者模式4),并根据使用当前时刻之前的时频资源的终端设备的终端模式,估计使用当前时刻之后的时频资源的终端设备的终端模式,并根据估计得到的终端模式进行资源选择,进而避免模式3的终端设备和模式4的终端设备在收发数据时相互干扰。
下面,通过具体实施例对获取终端模式的方法、以及资源选择的方法进行详细说明。需要说明的是,下面几个具体实施例可以相互结合,对于相同或相似的内容,在不同的实施例中不再进行重复说明。
图3为本申请提供的终端模式获取方法的流程示意图。请参见图3,该方法可以包括:
S301、第一终端设备获取至少两种终端信息,至少两种终端信息为能够使用共享资源池的终端设备的终端信息,共享资源池被至少两种终端模式的终端设备共用,终端信息包括终端模式和终端类型。
可选的,第一终端设备可以为V2X场景中的任意一个设备。例如,第一终端设备可以为车辆、UE、RSU等设备。
可选的,终端信息中包括终端模式和终端类型。终端模式可以包括第一终端模式和第二终端模式,第一终端模式为模式3(mode3),第二终端模式为模式4(mode4),其中,对于一个终端设备而言,该终端设备的终端模式可以不同,例如,在第一时刻,终端设备的终端模式可以为模式3,在第二时刻,终端设备的终端模式还可以为模式4。终端类型可以包括第一终端类型和第二终端类型,第一终端类型为R.14(Release.14),第二终端类型为R.15(Release.15)。相应的,终端信息可以至少包括如下四种:R.14mode3、R.14mode4、R.15mode3、R.15mode4。
可选的,对于一个共享资源池来说,预先配置能够使用该共享资源池中的终端设备的终端信息。可选的,能够使用共享资源池的终端设备的至少两种终端信息可以为基站广播、或者通过无线资源控制RRC专用信令发送的,也可以为在第一终端设备中预先配置的。
可选的,能够使用共享资源池的终端设备的一部分终端信息可以在协议中规定,另一部分终端信息可以由基站提供或者预先配置。相应的,第一终端设备可以在协议中获取一部分终端信息,并通过基站或者预先配置获取另一部分终端信息。
例如,协议中可以规定能够使用共享资源池的终端信息包括R.15mode3和R.15mode4,基站广播的、能够使用共享资源池的终端信息包括R.14mode4,则第一终端设备可以确定能够使用共享资源池的终端设备的终端信息包括:R.15mode3、R.15mode4和R.14mode4。
由于共享资源池可以被至少两种终端模式的终端设备共用,且终端模式包括模式3和模式4,因此,共享资源池可以被模式3的终端设备和模式4的终端设备共用。需要说明的是,能够使用共享资源池的终端设备的终端信息中不能同时包括R.14mode3和R.14mode4。
可选的,能够使用共享资源池的终端设备的至少两种终端信息可以至少包括如下四种类型:
R.14mode3、R.15mode4;
R.14mode4、R.15mode3;
R.14mode3、R.15mode3、R.15mode4;
R.14mode4、R.15mode3、R.15mode4。
需要说明的是,共享资源池也可以为终端模式相同、终端类型不同的终端设备共 用。但是,当共享资源池被终端模式相同、终端类型不同的终端设备共用时,例如,共享资源池被终端信息为R.14mode3终端设备和终端信息为R.15mode3的终端设备共用,或者共享资源池被终端信息为R.14mode4的终端设备和终端信息为R.15mode4的终端设备共用,不存在资源使用不合理而导致的干扰问题,因此,本申请所讨论的方案中不包括该种情况。
需要说明的是,在第一终端设备获取得到至少两种终端信息之后,若第一终端设备判断至少两种终端信息中的终端模式相同,例如,至少两种终端信息中包括R.14mode3和R.15mode3,或者至少两种终端信息中包括R.14mode4和R.15mode4,则第一终端设备可以按照现有技术中的处理方式处理。
S302、第一终端设备接收第二终端设备发送的控制信息,控制信息用于指示第二终端设备在共享资源池的第一时段内的第一时频资源上发送数据。
可选的,控制信息可以为调度分配(Scheduling Assignment,简称SA)信息、或者侧行链路控制信息(Sidelink Control Information,简称SCI)。
在V2X场景中,在终端设备发送数据时,同时也发送对应的控制信息。其中,终端设备通常以广播的形式发送数据和控制信息。可选的,对于同一业务中的数据,终端设备通常周期性的发送。
可选的,当第二终端设备发送数据之前,第二终端设备在共享资源池中选择用于发送控制信息的时频资源和用于发送数据的时频资源,发送控制信息的时频资源和用于发送数据的时频资源之间具有预设对应关系。在第二终端设备在控制信息对应的时频资源上发送控制信息时,并在控制信息中携带包括发送数据时使用的时频资源的指示信息。这样,在其它终端设备(例如,第一终端设备)接收到第二终端设备发送的控制信息后,可以在控制信息所指示的时频资源上接收数据。
需要说明的是,控制信息中还可以包括其它内容,例如,调制与编码策略(Modulation and Coding Scheme,简称MCS)信息、优先级信息、时域时间间隔、及传输次数等,本申请对控制信息中包括的内容不做具体限定。
可选的,当第二终端设备的终端类型为第二终端类型(R.15)时,在第二终端设备发送的控制信息中包括第二终端设备的终端模式或终端类型(R.15)。
可选的,可以在控制信息中增加标志位,并通过新增的标志位中的内容指示第二终端设备的终端模式或终端类型。可选的,标志位中可以包括一个或多个比特位。
例如,当控制信息中包括终端模式时,可以在控制信息中增加1个比特位的标志位,当该标志位中的数值为0时,指示终端设备的终端模式为模式3,当该标志位中的数值为1时,指示终端设备的终端模式为模式4。
当控制信息中包括终端类型时,可以在控制信息中增加1个比特位的标志位,可以任意设置该标志位中的数值,即,只要控制信息中包括新增标志位时,则可以确定终端设备的终端模式为第二终端类型。
可选的,当控制信息中包括预留位时,可以使用预留位中的部分或全部,以通过预留位指示第二终端设备的终端模式或终端类型。
例如,当控制信息中包括终端模式时,可以使用2位预留位,其中,预留位中数值的默认值通常为0,当将该2位预留位被设置为01时,指示终端设备的终端模式为 模式3,当将该2位预留位被设置为11时,指示终端设备的终端模式为模式4。
当控制信息中包括终端类型时,可以使用1位预留位,并将该1位预留位中的数值设置为1,当判断该1位预留位中的数值不是0时,则可以确定终端设备的终端模式为第二终端类型。
S303、第一终端设备根据控制信息、及终端信息,确定第二终端设备在第一时频资源上发送数据时的终端模式。
可选的,可以通过至少如下两种可行的实现方式,确定第二终端设备的终端模式:
第一种可行的实现方式:
在该种可行的实现方式适用于所有的应用场景,即,至少两种终端信息可以为S301中所示的四种类型中的任意一种类型。具体实现方式可以如下:
第一终端设备判断控制信息中是否包括终端模式,其中,当第二终端设备的终端类型为第一终端类型(R.14)时,则控制信息中不包括终端模式,当第二终端设备的终端类型为第二终端类型(R.15)时,则控制信息中包括终端模式。
可选的,第一终端设备可以判断控制信息中是否包括新增标志位,若是,则确定控制信息中包括终端模式,否则,则确定控制信息中不包括终端模式。可选的,第一终端设备可以判断预留位中的数值是否全为0,若是,则确定控制信息中不包括终端模式,否则,则确定控制信息中包括终端模式。
若是,则第一终端设备将控制信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式。例如,当控制信息中包括的终端模式为模式3时,则确定第二终端设备的终端模式为模式3。当控制信息中包括的终端模式为模式4时,则确定第二终端设备在第一时频资源上发送数据时的终端模式为模式4。
若否,则第一终端设备在至少两种终端信息中确定第一终端信息,并将第一终端信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式,第一终端信息中的终端类型为第一终端类型。
可选的,若控制信息中不包括终端模式时,则可以确定第二终端设备的终端类型为第一终端类型(R.14),由于至少两种终端信息中不能同时包括R.14mode3和R.14mode4,因此,第一终端信息为R.14mode3或者R.14mode4,因此,根据第一终端信息可以唯一确定得到第二终端设备在第一时频资源上发送数据时的终端模式。例如,假设在至少两种终端信息中确定得到的第一终端信息为R.14mode3,则可以确定第二终端设备在第一时频资源上发送数据时的终端模式为模式3(mode3)。
第二种可行的实现方式:
在该种可行的实现方式适用于部分应用场景,即,至少两种终端信息中每两种终端信息的终端模式均不同、且每两种终端信息的终端类型均不同,相应的,至少两种终端信息的个数为两种,该两种终端信息包括R.14mode3和R.15mode4,或者,至少两种终端信息包括:R.14mode4和R.15mode3。具体实现方式可以如下:
第一终端设备判断控制信息中是否包括终端类型;其中,当第二终端设备的终端类型为第一终端类型(R.14)时,则控制信息中不包括终端类型,当第二终端设备的终端类型为第二终端类型(R.15)时,则控制信息中包括终端类型(包括的终端类型为R.15)。
若是,则第一终端设备在至少两种终端信息中确定第二终端信息,并将第二终端信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式,第二终端信息中的终端类型为第二终端类型。
若控制信息中包括终端类型,则可以确定第二终端设备的终端类型为第二终端类型(R.15),由于至少两个终端信息中同时只能包括R.15mode3与R.15mode4中的一个,因此,第二终端信息为R.15mode3或R.15mode4,因此,根据第二终端信息中包括的终端模式可以唯一确定得到第二终端设备的终端模式。例如,假设在至少两种终端信息中确定得到的第二终端信息为R.15mode3,则可以确定第二终端设备在第一时频资源上发送数据时的终端模式为模式3(mode3)。
若否,则第一终端设备将第一终端信息中包括的终端模式确定为第二终端设备在第一时频资源上发送数据时的终端模式,第一终端信息中的终端类型为第一终端类型。
若控制信息中不包括终端类型,则可以确定第二终端设备的终端类型为第一终端类型(R.14),由于至少两个终端信息中同时只能包括R.14mode3与R.14mode4中的一个,因此,第一终端信息为R.14mode3或R.14mode4,因此,根据第一终端信息中包括的终端模式可以唯一确定得到第二终端设备的终端模式。例如,假设在至少两种终端信息中确定得到的第一终端信息为R.14mode3,则可以确定第二终端设备在第一时频资源上发送数据时的终端模式为模式3(mode3)。
需要说明的是,还可以通过其它可行的实现方式确定第二终端设备的终端模式。
例如,假设至少两种终端信息中包括R.14mode3和R.15mode4,则规定在R.15类型的终端设备发送控制信息时,在控制信息中携带指示信息,相应的,在第一终端设备接收到控制信息之后,判断控制信息中是否包括指示信息,若是,则可以确定第二终端设备的终端模式为模式4,否则,则可以确定第二终端设备的终端模式为模式3。
例如,假设至少两种终端信息中包括R.14mode4和R.15mode3,则规定在R.15类型的终端设备发送控制信息时,在控制信息中携带指示信息,相应的,在第一终端设备接收到控制信息之后,判断控制信息中是否包括指示信息,若是,则可以确定第二终端设备的终端模式为模式3,否则,则可以确定第二终端设备的终端模式为模式4。
例如,假设至少两种终端信息中包括R.14mode3、R.15mode3和R.15mode4,则规定在R.15mode4类型的终端设备发送控制信息时,在控制信息中携带指示信息,相应的,在第一终端设备接收到控制信息之后,判断控制信息中是否包括指示信息,若是,则可以确定第二终端设备的终端模式为模式4,否则,则可以确定第二终端设备的终端模式为模式3。
例如,假设至少两种终端信息中包括R.14mode4、R.15mode3和R.15mode4,则规定在R.15mode3类型的终端设备发送控制信息时,在控制信息中携带指示信息,相应的,在第一终端设备接收到控制信息之后,判断控制信息中是否包括指示信息,若是,则可以确定第二终端设备的终端模式为模式3,否则,则可以确定第二终端设备的终端模式为模式4。
需要说明的是,在第一时段内,第一终端设备可以接收到多个第二终端设备发送的多个控制信息,每一个控制信息均可以指示一个第一时频资源,因此,第一时频资源的个数为至少一个。下面,结合图4,对第一时频资源进行详细说明。
图4为本申请提供的第一时频资源的示意图。请参见图4,横轴表示时域,纵轴表示频域,坐标原点表示当前时刻。当前时刻之前的一个时段为第一时段,第一时频资源为第一时段内的部分或全部时频资源。
请参见图4,第一时频资源可以为第一时段内灰色部分所对应的时频资源,一个第一时频资源可以为一个子帧上频域连续的多个资源块,例如,第-15个子帧上、频域第5-8个资源块构成的时频资源可以为一个第一时频资源,第-13个子帧上、频域第1-7个资源块构成的时频资源可以为一个第一时频资源。
本申请提供的终端模式获取方法,在配置共享资源池时,配置了能够使用该共享资源池的终端设备的至少两种终端信息,当第二终端设备需要在共享资源池中的第一时频资源上发送数据时,第二终端设备发送控制信息,相应的,在第一终端设备接收到第二终端设备发送的控制信息之后,可以根据至少两种终端信息和控制信息确定得到第二终端设备在第一时频资源上发送数据时的终端模式。
在图2所示实施例的基础上,可选的,在第一终端设备确定得到每一个第二终端设备在对应的第一时频资源上发送数据时的终端模式之后,当第一终端设备的终端模式为R.15mode4时,第一终端设备可以根据确定得到的终端模式在共享资源池的第二时段(请参见图4,第二时段为当前时刻之后的时段)内的时频资源中选择备选时频资源,具体过程请参见图5-图6所示的实施例。当第一终端设备的终端模式为R.15mode3时,第一终端设备可以协助基站进行时频资源分配,具体过程请参见图7所示的实施例。
下面,通过图5-图6所示的实施例,介绍两种第一终端设备(R.15mode4)在第二时段内的时频资源中选择备选时频资源的方式。
图5为本申请提供的第一终端设备选择备选时频资源方法的流程示意图一。请参见图5,该方法可以包括:
S501、第一终端设备在至少一个第一时频资源中确定第二时频资源和第三时频资源。
其中,在第二时频资源上发送数据的终端设备的终端模式为第一终端模式,在第三时频资源上发送数据的终端设备的终端模式为第二终端模式。
在本发明实施例中,第一终端设备在第一时段内可以接收到至少一个控制信息,每一个控制信息指示一个第一时频资源,相应的,第一时频资源的个数也为至少一个。
可选的,第一终端设备可以分别确定在每一个第一时频资源上发送数据的终端设备的终端模式,当在一个第一时频资源上发送数据的终端设备的终端模式为第一终端模式,则可以将该第一时频资源确定为第二时频资源。当在一个第一时频资源上发送数据的终端设备的终端模式为第二终端模式,则可以将该第一时频资源确定为第三时频资源。
在S501之后,第一终端设备根据第二时频资源对应的时域时间间隔、第三时频资源对应的时域时间间隔、及第三时频资源对应的信号强度,在第二时段内的时频资源中确定备选时频资源。可选的,第一终端设备可以通过S502-S505确定备选时频资源。当然,第一终端设备还可以通过其它可行的实现方式确定备选时频资源,本申请对此不作具体限定。
S502、第一终端设备根据第二时频资源对应的时域时间间隔,在第二时段内的时频资源中确定第五时频资源,第五时频资源对应的终端模式与在第二时频资源上发送数据的终端设备的终端模式相同。
可选的,第二时频资源对应的时域时间间隔是指,在第二时频资源上发送数据的终端设备的时域时间间隔,其中,对于不同的业务,终端设备的时域时间间隔可能相同,也可能不同。
可选的,在终端设备在第二时频资源上发送一种业务中数据时,可以在对应的控制信息中携带该终端设备在该种业务中第二时频资源对应的时域时间间隔,相应的,第一终端设备可以在控制信息中获取第二时频资源对应的时域时间间隔。当控制信息中未携带时域时间间隔时,则第一终端设备可以将在第二时频资源上发送数据的终端设备的所有可用时域时间间隔确定为第二时频资源对应的时域时间间隔。
可选的,可以在第二时频资源在时域上的编号加第二时频资源对应的时域时间间隔,直至得到的时域资源位于第二时间段内。
例如,请参见图4,假设第二时频资源为第-9个子帧上、频域第2-8个资源块,再假设第二时频资源对应的时域时间间隔为10,则第五时频资源为第1(-9+10)个子帧上、频域第2-8个资源块。
S503、第一终端设备根据第三时频资源对应的时域时间间隔,在第二时段内的时频资源中确定第六时频资源,第六时频资源的终端模式与第三时频资源的终端模式相同,第六时频资源的信号强度与第三时频资源的信号强度相同。
可选的,可以在对应的控制信息中获取第三时频资源对应的时域时间间隔。当在控制信息中无法获取得到第三时频资源对应的时域时间间隔时,则不再继续根据该第三时频资源对应的时域时间间隔在第二时段内的时频资源中确定第六时频资源。
第三时频资源对应的信号强度是指,第一终端设备可以在第三时频资源上检测到的信号强度。例如,信号强度可以为参考信号接收功率(Reference Signal Received Power,简称RSRP)。其中,在第三时频资源上发送数据的终端设备的发射功率越大,第一终端设备在第三时频资源上检测到的信号强度越大,在第三时频资源上发送数据的终端设备与第一终端设备的距离越近,第一终端设备在第三时频资源上检测到的信号强度越大。
需要说明的是,第一终端设备可以通过现有技术中的方法获取第三时频资源对应的信号强度,本申请对此不再进行赘述。
还需要说明的是,第一终端设备确定第六时频资源的方法与在S502中确定第五时频资源的方法类似,此处不再进行赘述。
还需要说明的是,S502和S503的执行没有先后顺序,可以同时执行S502和S503,也可以顺序执行S502和S503。当顺序执行S502和S503时,可以先执行S502,也可以先执行S503。
在S502和S503之后,第一终端设备可以根据第五时频资源、及第六时频资源的信号强度,在第二时段内的时频资源中确定备选时频资源。可选的,可以通过S504-S505确定备选时频资源。当然,第一终端设备还可以通过其它可行的实现方式确定备选时频资源,本申请对此不作具体限定。
S504、第一终端设备将第二时段内的时频资源中除第五时频资源外的时频资源确定为初级备选时频资源。
可选的,第一终端设备在第二时段内的时频资源中剔除第五时频资源,得到初始备选时频资源。
S505、第一终端设备根据第六时频资源的信号强度,在初级备选时频资源中确定备选时频资源。
可选的,第一终端设备在初级备选时频资源中剔除信号强度大于预设阈值的第六时频资源,得到备选时频资源。
需要说明的是,在实际应用过程中,还可以先根据第六时频资源的信号强度得到初级备选资源,再在初级备选资源中剔除第五时频资源以得到备选时频资源。当然,还可以同时在第二时段内的时频资源中剔除第五时频资源、及信号强度大于预设阈值的第六时频资源,以得到备选时频资源。本申请对此不作具体限定。
还需要说明的是,第五时频资源和第六时频资源通常仅为第二时段内的时频资源中的一部分,在根据第五时频资源和第六时频资源确定得到备选时频资源之后,还需要根据第二时段内的时频资源中、除第五时频资源和第六时频资源外的时频资源,进一步在备选时频资源中选择最终使用的时频资源。可选的,可以通过现有技术中的方法,在备选时频资源中选择最终使用的时频资源,本申请不再进行赘述。
还需要说明是,还可以通过如下可行的实现方式选择备选时频资源:
在S504之前,第一终端设备可以根据需要发送数据的大小,确定需要使用的资源块的个数,并根据需要使用的资源块的个数,在第二时段内的时频资源中确定可用时频资源。例如,请参见图4,假设需要使用的资源个数为6个,第一终端设备可以在第5个子帧上,确定可用时频资源为第1-6个资源块、第2-7个资源块、第3-8个资源块、第4-9个资源块、及第5-10个资源块,同理,在第6个子帧上,也可以确定得到5个可用时频资源。请参见图4,由于第二时段内包括10个子帧,因此,第一终端设备在第二时段内可以确定得到5*10=50个可用时频资源。
第一终端设备在第二时段内确定得到所有可用时频资源之后,第一终端设备在所有可用时频资源中剔除与第五时频资源具有重合资源块的可用时频资源,并剔除与信号强度大于预设阈值的第六时频资源具有重合资源块的可用时频资源,得到备选可用时频资源。
例如,请参见图4,假设一个第五时频资源为第5个子帧上、第2-4个资源块,由于第1-6个资源块、第2-7个资源块、第3-8个资源块、第4-9个资源块对应的可用时频资源中均与第2-4个资源块有重合,则在所有可用资源中剔除第1-6个资源块、第2-7个资源块、第3-8个资源块、第4-9个资源块对应的可用时频资源,相应的,第5个子帧上剩余的可用时频资源为第5-10个资源块对应的时频资源。
在第一终端设备确定得到备选可用时频资源之后,第一终端设备可以根据现有技术中的方式在备选可用时频资源中选择最终使用的时频资源,本申请对此不再进行赘述。
在图5所示的实施例中,确定得到的第五时频资源在未来可能被模式3的终端设备使用,由于模式3的终端设备在收发数据时对其它终端设备的干扰要求较为严格, 因此,第一终端设备将第五时频资源排除在备选时频资源之外,可以保证第一终端设备一定不在第五时频资源上发送数据,进而可以避免第一终端设备对可能在第五时频资源上发送数据的模式3的终端设备造成干扰。进一步的,确定得到的第六时频资源在未来可能被模式4的终端设备使用,当第一终端设备估计的第六时频资源的信号强度大于预设阈值时,则说明未来在第六时频资源上发送数据的终端设备的功率过大、或者与第一终端设备的距离过近,因此,第一终端设备将第六时频资源中信号强度大于预设阈值的时频资源排除在备选时频资源之外,可以避免第一终端设备与在信号强度大于预设阈值的第六时频资源上发送数据的终端设备之间相互干扰。由上可知,第一终端设备通过估计第二时段内的时频资源对应的终端模式,可以准确的在第二时段的时频资源中选择备选时频资源。
图6为本申请提供的第一终端设备选择备选时频资源方法的流程示意图二。请参见图6,该方法可以包括:
S601、第一终端设备根据至少一个第一时频资源对应的终端模式、以及第一时频资源对应的时域时间间隔,确定第二时段内的时频资源中至少一个第四时频资源的对应的终端模式。
可选的,至少一个第四时频资源中包括图5所示实施例中的第五时频资源和第六时频资源。
可选的,第一终端设备可以根据至少一个第一时频资源对应的时域时间间隔,在第二时段内的时频资源中确定至少一个第四时频资源。其中,每一个第四时频资源与其对应的第一时频资源的终端模式相同。
需要说明的是,第一终端设备确定第四时频资源的过程,与S502中确定第五时频资源的过程类似,此处不再进行赘述。
S602、第一终端设备根据至少一个第一时频资源对应的信号强度、以及第一时频资源对应的时域时间间隔,确定至少一个第四时频资源的信号强度。
可选的,第四时频资源对应的信号强度,与其对应的第一时频资源对应的信号强度相同。
在S601和S602之后,第一终端设备根据第四时频资源对应的终端模式和第四时频资源对应的信号强度,在第二时段内的时频资源中确定备选时频资源。可选的,第一终端设备可以根据S603-S604在第二时段内的时频资源中确定备选时频资源。当然,第一终端设备还可以根据其它可行的实现方式确定备选时频资源,本申请对此不作具体限定。
S603、第一终端设备根据至少一个第四时频资源对应的终端模式,在至少一个第四时频资源中确定第五时频资源和第六时频资源,第五时频资源对应的终端模式为第一终端模式,第六时频资源对应的终端模式为第二终端模式。
可选的,当第一终端设判断一个第四时频资源对应的终端模式为第一终端模式,则第一终端设备将该第四时频资源确定为第五时频资源。当第一终端设备判断一个第四时频资源对应的终端模式为第二终端模式,则第一终端设备将该第四时频资源确定为第六时频资源。
S604、第一终端设备根据第五时频资源对应的信号强度、第一终端模式对应的第 一阈值、第六时频资源对应的信号强度、及第二终端模式对应的第二阈值,在第二时段内的时频资源中确定备选时频资源。
第一终端模式对应第一阈值,第二终端模式对应第二阈值,由于模式3的终端设备对其它终端设备的干扰要求,比模式4的终端设备对其它终端设备的干扰要求高。因此,第一阈值小于第二阈值。
可选的,可以将信号强度大于第一阈值的第五时频资源、以及信号强度大于第二阈值的第六时频资源排除在备选时频资源之外。
需要说明的是,第四时频资源通常仅为第二时段内的时频资源中的一部分,在根据第四时频资源确定得到备选时频资源之后,还需要根据第二时段内的时频资源中、除第四时频资源外的时频资源,进一步在备选时频资源中选择最终使用的时频资源。可选的,可以通过现有技术中的方法,在备选时频资源中选择最终使用的时频资源,本申请不再进行赘述。
在图6所示的实施例中,第一终端设备先在第二时段内的时频资源中确定至少一个第四时频资源,并获取每一个第四时频资源对应的终端模式和信号强度。不同的终端模式对应不同的阈值,第一终端设备根据第四时频资源对应的终端模式,在至少一个第四时频资源中确定第五时频资源和第六时频资源,并根据第五时频资源对应的信号强度、第一终端模式对应的第一阈值、第六时频资源对应的信号强度、及第二终端模式对应的第二阈值,在第二时段内的时频资源中确定备选时频资源。由于模式3的终端设备对其它终端设备的干扰要求与模式4的终端设备对其它终端设备的干扰要求不同,因此,通过上述方法可以准确的在第二时段的时频资源中选择备选时频资源。
下面,通过图7所示的实施例,对第一终端设备(R.15mode3)协助基站选择时频资源的方法进行详细说明。
图7为本申请提供的第一终端设备协助基站选择备选时频资源方法的流程示意图。请参见图7,该方法可以包括:
S701、第一终端设备根据第二终端设备在至少一个第一时频资源上发送数据时的终端模式、及至少一个第一时频资源对应的时域时间间隔,在共享资源池的第二时段内的时频资源中确定第六时域资源。
其中,第六时域资源的终端模式为第二终端模式。
可选的,第一终端设备可以先根据至少一个第一时频资源的终端模式,在至少一个第一时频资源中确定第三时频资源,其中,在第三时频资源上发送数据的终端设备的终端模式为第二终端模式,然后,第一终端设备可以根据第三时频资源对应的时域时间间隔,在共享资源池中确定第六时频资源。
