Abstract
本公开实施例提供了一种辅助UE的选择方法、装置、通信设备及存储介质;辅助UE的选择方法,包括:发送所述第一UE的第一信息;其中,所述第一信息,用于供第二UE确定所述第一UE是否能够作为用于提供资源选择辅助信息的辅助UE。本公开实施例所提供的辅助UE的选择方法,可以准确确定出第一UE是否能够作为用于提供资源选择辅助信息的辅助UE,从而使得第二UE能够获得比较准确的资源选择辅助信息。
Description
本公开涉及但不限于通信技术领域,尤其涉及一种辅助UE的选择方法、装置及存储介质。
在相关技术中,为了支持用户设备(User Equipment,UE)与UE之间的直接通信,引入了直连链路(SideLink,SL)通信方式;其中,UE与UE之间的接口为PC-5。根据发送UE和接收UE的对应关系,在SL上支持三种传输方式,单播,多播和广播。
当UE在SL上进行自主选择发送资源时,如果临近的UE选择了相同的发送资源,可能造成发送碰撞,降低了可靠性。为了避免这种碰撞,引入了感知(sensing)机制。UE需要持续或者在一段时间内监听其他UE发送的直连链路控制信息(Sidelink Control Information,SCI),以获得其他UE的资源选择信息;并在UE自己进行资源选择时,避免选择相同的发送资源。如果部分资源没有进行感知,则在资源选择时,不能选择未进行感知的这部分资源。同时根据信道拥塞测量结果,发送UE选择不同的发送资源,避免信道过于拥塞。在有些SL发送UE可能不具备信道感知和测量功能,此时需要其他UE来为这个UE提供资源选择辅助信息,这个UE根据收到的资源选择辅助信息,进行资源选择。

在一些实施例中,移动状况信息,包括:
移动指示信息,用于指示第一UE是否为移动UE。
此处的移动指示信息可以包括:第一移动指示信息和第二移动指示信息。例如,第一移动指示信息为“1”,用于指示第一UE为移动UE;第二移动指示信息为“0”,用于指示第一UE不是移动UE或者固定UE。
如此,在本公开实施例中,第一UE通过向第二UE发送移动指示信息,以使得第二UE能够知晓第一UE是否在移动、以确定出第一UE是否会很快靠近自身。
在一些实施例中,移动状况信息,包括:

在一些实施例中,移动参数包括但不限于以下之一:
第一移动速率参数,用于指示移动UE的移动速率高于或等于预定速率;

在本公开实施例中,当指示移动UE(即第一UE)的移动速率高于或等于预定速率时,可以确定出第一UE的移动性相对比较高,进而可以让第二UE知晓第一UE是否会在相对比较短时间内靠近自身;当指示移动UE的移动速率低于或等于预定速率时,可以确定出第二UE的移动性相对比较低,进而可以让第二UE知晓第一UE是否会在相对比较长时间才会靠近自身。如此,可以使得第二UE通过移动参数确定第一UE是否会很快靠近自身。
当然,在其它的实施例中,移动速率参数还可以是包括更多分类的移动速率参数;例如,移动速率参数包括:第1移动速率参数、第2移动速率参数、……、第N移动速率参数;其中,第1移动速率参数,用于指示移动UE的移动速率在第1速率阈值范围内;第2移动速率参数,用于指示移动UE的移动速率在第2速率阈值范围内;以此类推;第N移动速率参数,用于指示移动UE的移动速率在第N速率阈值范围内;第1速率阈值范围的下限值大于或等于第2速率阈值范围的上限值,第2速率阈值范围的下限值大于或等于第3速率阈值范围的上限值,……,第N-1速率阈值范围的下限值大于或等于第N速率阈值范围的上限值。此处的N为大于2的正整数。

此处的相对位置信息,可以用于指示第一UE相对于第二UE的距离,也可以用于指示第一UE相对于第二UE的空间位置信息等。
在一些实施例中,可以预先建立各UE所在区域的位置信息。如此,可以根据第一UE所在的区域以及第二UE所在的区域,确定出第一UE与第二UE之间的距离。
在本公开实施例中,可以通过第一UE将第一UE的区域标识,以使得第二UE知晓第一UE所在的区域,从而确定出第一UE是否在第二UE的周围;也可以通过第一UE将相对位置信息发送给第二UE,以使得第二UE能够知晓第一UE是否在第二UE的周围。如此,本公开实施例可以使得第二UE准确确定出第一UE是否在自身的周围。
在一些实施例中,资源选择辅助消息,包括但不限于以下至少之一:

在本公开实施例中,可以通过第一UE发送第一UE的第一信息,该第一信息可以供第二UE确定第一UE是否能够作为提供资源选择辅助信息的辅助UE。如此,在本公开实施例中可以准确确定出第一UE是否能够作为提供资源选择辅助信息的辅助UE,从而使得第二UE能够获得比较准确的资源选择辅助信息,进而有利于第二UE基于接收到的资源选择辅助信息进行资源选择时,尽量降低资源碰撞和/或信道拥塞等情况的出现。
且,在本公开实施例中,可以通过第一UE发送空间位置信息给第二UE,以使得第二UE能够知晓第一UE是否在自身周围;和/或,通过第一UE发送移动状况信息给第二UE,以使得第二UE能够知晓第一UE是否很快会在自身周围。如此,本公开实施例可以使得第二UE能够选择出离自己相对较近的第一UE作为发送资源选择辅助信息的辅助UE,如此,可以进一步提高获取的资源选择辅助信息的准确性,进而进一步降低资源碰撞和/或信道拥塞发生的概率。
需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

在本公开的一些实施例中,第一信息可以为步骤S21中所述的第一信息,在此不再赘述。
在本公开实施例中,可以通过第一UE在接收到触发请求消息时,才发送第一UE的第一信息。如此,本公开实施例只有在接收到触发请求消息时才发送第一信息,相对于一直发送第一UE的第一信息来说,能够大大节省网络资源。
需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图4所示,本公开实施例提供一种辅助UE的选择方法,应用于第一UE,包括:

本公开实施例提供的一种辅助UE的选择方法,包括:
确定发送第一UE的第一信息的周期;
基于周期,周期性发送第一UE的第一信息。

在另一些实施例中,第一UE预先配置周期。例如,第一UE预先配置上报第一信息的周期,或者,第一UE获取到通信协议中预先配置的上报第一信息的周期。
在其它实施例中,上述的周期也可以通过任何可行的方式确定,本公开实施例并不对此做出限定。
在本公开实施例中,第一UE可以周期性的上报第一UE的第一信息。如此,本公开实施例相对于一直发送第一UE的第一信息来说,一方面能够节省网络资源;另一方面能够适用更多的应用场景,实现上报触发消息的灵活配置。
当然,在其它的实施例中,第一UE也可以非周期性的发送第一UE的第一信息。如此,也可以适用更多的应用场景,实现更灵活的配置。
在本公开的一些实施例中,第一信息可以为步骤S21中所述的第一信息,在此不再赘述。
需要说明的是,本领域内技术人员可以理解,本公开实施例提供的方法,可以被单独执行,也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

再例如,第一UE获取基站配置的触发事件。
在另一些实施例中,一种辅助UE的选择方法,也可以包括:获取触发第一UE发送第一信息的触发事件。
如此,在本公开实施例中,第一UE可以通过多种方式确定触发事件,例如,可以基于第一UE预先配置确定触发事件,也可以获取基站配置的触发事件,还可以接收第二UE为第一UE配置的触发事件。如此本公开实施例,可以适用更多的应用场景的辅助UE的准确选择。
在一些实施例中,触发事件包括但不限于以下至少之一:

例如,第一UE在第一时刻的区域为区域1,在第二时刻的区域为区域2。在该场景下,第一UE所在的区域发生变化,如此可以触发第一UE发送第一消息。
又如,在1秒内第一UE移动的距离超过50米。在该场景下,第一UE位置发生变化,如此可以触发第一UE发送第一消息。
再如,当前时刻,第一UE与第二UE的距离大于50米。在该场景下,第一UE和第二UE之间的距离超过了预定距离,第一UE与第二UE之间相距比较远;如此也可以触发第一UE发送第一消息。
如此,在本公开实施例中,当第一UE离开当前的区域、或者第一UE位置变化超过一定阈值,或者第一UE与第二UE之间的距离超过一定阈值时,均可以作为引起第一UE上报第一信息的触发事件。
在本公开的一些实施例中,第一信息可以为步骤S21中所述的第一信息,在此不再赘述。
在本公开实施例中,可以通过第一UE在获取到触发事件时,基于触发事件发送第一UE。如此,可以使得第二UE能够及时知晓第一UE当前所在的位置是否在自身的周围或者很快靠近自身,从而能够使得第二UE及时确定出第一UE是否能够作为提供资源选择辅助信息的辅助UE,进而降低资源碰撞和/或信道拥塞等情况的出现。
且,在本公开实施例中,能够通过多种方式获取触发事件和/或触发事件可以为多种形式,从而能够适用更多的应用场景,实现辅助UE选择的灵活配置。

例如,标识信息为“1”,用于指示第一UE能够为第二UE提供选择辅助信息。
在本公开的一些实施例中,第一信息可以为步骤S21中所述的第一信息,在此不再赘述。
在本公开实施例中,第一UE可以在确定第一UE能够为第二UE提供资源选择辅助信息时,才发送第一信息;且该第一消息中携带指示第一UE为第二UE提供资源选择辅助信息的标识信息。如此,可以使得第二UE知晓第一UE能够为第二UE提供资源选择辅助信息,从而可以加大第二UE确定第一UE能够作为提供资源选择辅助信息的辅助UE的概率。
且,本公开实施例中,标识信息携带在第一信息发送,无需额外单独发送标识信息,从而也能够节省网络资源。

在一些实施例中,确认消息或拒绝消息可以是通过SL发送的。
此处的确认消息或拒绝消息可以携带在信令中发送。
例如,第一UE和第二UE建立单播无线资源控制(Radio Resource Control,RRC)连接,则第一UE接收第二UE发送的携带确认消息的RRC信令。当然,在其它的实施例中,第一UE也可以接收携带确认消息或拒绝消息的信令,例如,可以媒体访问控制层(Media Access Control,MAC)信令。当然,在其它的实施例中,第一UE也可以接收第二UE广播的***信息,该***信息中携带有确认消息或拒绝消息。
此处的确认消息或拒绝消息可以携带在信令的信息指示域中。此处的确认消息或拒绝消息可以通过预定比特数量指示。例如确认消息可以为“1”、拒绝消息可以为“0”;又如确认消息可以为“10”,拒绝消息可以为“00”。
在本公开的一些实施例中,第一信息可以为步骤S21中所述的第一信息,在此不再赘述。
在本公开实施例中,第一UE可以通过接收第二UE基于第一信息发送的确认消息,确定出第二UE同意由第一UE为其提供资源选择辅助信息;或者,第一UE可以通过接收第二UE基于第一信息发送拒绝消息,确定出第二UE不同由第一UE为期提供选择辅助信息。如此,在本公开实施例中,第一UE可以通过接收到基于第一信息返回的不同信息,知晓第一UE是否能够作为第二UE提供资 源选择辅助信息的辅助UE。
