为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示例性实施例提供的通信系统的框图,该通信系统包括接入网12和终端14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。在本申请实施例中,上述为终端14提供无线通信功能的装置统称为网络设备。
终端14可以包括各种具有无线通信功能的手持设备、车载设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端。接入网设备120与终端14之间通过某种空口技术互相通信,例如Uu接口。
在车联网通信中,网络设备和终端可以分别是其中一个车载设备,而且网络设备和终端之间的通信,可以通过车载设备之间进行D2D(Device to Device)的直连通信。
图2示出了本公开一个示例性实施例提供的波束管理方法的流程图。该方法可以应用于图1所示的终端中,该方法包括:
步骤202,根据终端的移动速度确定目标波束管理参数,目标波束管理参数是与移动速度对应的波束管理参数;
由于终端是移动终端,因此会被用户携带至任何可能的地方。可选地,终端通过内置传感器来获取自身的移动速度。内置传感器包括但不限于:全球定位芯片、加速度传感器或六轴加速度传感器。本实施例对终端如何获取自身的移动速度不加以限定,还可以通过基于基站的三角定位法、基于车联网终端的三角定位法等其他可能方式。
终端根据不同的移动速度确定不同的波束管理参数。可选地,设置有至少两个移动速度区间,不同的移动速度区间对应不同的波束管理参数。
在一个示例中,至少两个移动速度区间包括:中速(medium speed)区间和高速(high speed)区间。当终端的移动速度属于中速区间时,采用与中速区间对应的波束管理参数;当终端的移动速度属于高速区间时,采用与高速区间对应的波束管理参数。
在一个示例中,至少两个移动速度区间包括:低速区间、中速区间和高速区间。当终端的移动速度属于低速区间时,采用与低速区间对应的波束管理参数;当终端的移动速度属于中速区间时,采用与中速区间对应的波束管理参数;当终端的移动速度属于高速区间时,采用与高速区间对应的波束管理参数。
需要注意的是,这里考虑的终端移动速度可以是终端的绝对移动速度,比如网络设备静止时,终端的移动速度即为终端的绝对移动速度;终端的移动速度还可以是终端的相对移动速度,比如当为车联网通信时,两个车载设备可能都在移动,那么终端移动速度即为本车载终端与通信对侧的车载终端的相对移动速度。
在一个示例中,波束管理参数包括如下参数中的至少一项:
1、波束测量的参考信号或参考信号集合;
参考信号是波束测量的测量对象。参考信号的类型包括:SSB或CSI-RS。
参考信号为一个或多个。当测量对象为多个参考信号时,可称为参考信号集合。
2、波束测量结果中上报的参考信号个数;
上报的参考信号的个数可以为:1、2、4、8或16……。
3、波束测量结果中上报的测量值的比特数;
在波束测量结果中需要上报测量值。测量值是采用n比特的比特码字来表示的。不同比特数量对应的比特开销不同。通过减少每个参考信号的测量值上报时所占用的比特数,能够减少信令开销。
4、波束测量结果的上报周期。
不同的移动速度(区间)对应不同的上报周期。可选地,移动速度越快,上报周期越小。
步骤204,根据目标波束管理参数进行波束管理。
终端根据目标波束管理参数进行波束测量,也即对波束对应的参考信号进 行测量,得到波束测量结果。终端将波束测量结果上报给网络设备。网络设备根据波束测量结果确定在发送下行数据时的发送波束,网络设备向终端通知发送波束的信息。
终端根据发送波束的信息确定自身的接收波束。终端采用接收波束接收网络设备发送的下行数据。
综上所述,本实施例提供的方法,通过根据终端的移动速度确定目标波束管理参数,根据目标波束管理参数进行波束管理。由于不同的移动速度可对应不同的波束管理参数,因此在终端的移动速度较高时,能够采用合理的波束管理参数来减少信令开销和减小时延。
上述步骤202存在两种不同的实现方式:
第一种可能的实现方式:存在多组波束管理参数,根据终端的移动速度在多组波束管理参数中确定出目标波束管理参数。
第二种可能的实现方式:存在一组基础波束管理参数,根据终端的移动速度在基础波束管理参数的基础上,生成目标波束管理参数。
下面采用图3实施例对第一种可能的实现方式进行介绍:
图3示出了本公开另一个示例性实施例提供的波束管理方法的流程图。该方法可以应用于图1所示的终端中,该方法包括:
步骤302,根据终端的移动速度,在至少两组波束管理参数中确定目标波束管理参数;
终端确定至少两组波束管理参数,每组波束管理参数对应各自的移动速度(或移动速度区间)。表一示例性的示出了移动速度区间和波束管理参数之间的对应关系。
表一
移动速度区间 | 波束管理参数 |
低速区间[v1,v2) | 第一波束管理参数 |
中速区间[v2,v3) | 第二波束管理参数 |
高速区间[v3,v4) | 第三波束管理参数 |
其中,至少两组波束管理参数对应不同的移动速度区间。
在一种设计中,该至少两组波束管理参数是终端内置的,比如出厂设置; 在另一种设计中,该至少两组波束管理参数是网络设备向终端配置的。
以多组波束管理参数中任意两个区间为第一区间和第二区间为例:当移动速度属于第一区间时,终端将至少两组波束管理参数中的第一波束管理参数,确定为目标波束管理参数;当移动速度属于第二区间时,终端将至少两组波束管理参数中的第二波束管理参数,确定为目标波束管理参数。
根据波束管理参数的内容不同,示例性的实施如下:
1、以波束管理参数包括参考信号集合为例:网络设备向终端配置多组参考信号集合,不同参考信号集合对应不同的移动速度区间。终端在移动速度属于低速区间时,使用参考信号集合1;在移动速度属于中速区间时,使用参考信号集合2;在移动速度属于高速区间时,使用参考信号集合3。示例性的,移动速度还可以更加细分,这样针对不同移动速度区间的参考信号集合需要更多。比如:针对更高移动速度对应的每个参考信号,网络设备发送时使用的波束更宽,那么更高移动速度对应的波束参考信号集合中的参考信号的数目越少。
2、以波束管理参数包括上报的参考信号个数为例:网络设备向终端配置多个个数上限,该个数上限是指终端每次进行波束测量结果的上报时,所上报的最大参考信号个数限制。不同的个数上限对应不同的移动速度区间。可选地,移动速度越大,上报的参考信号个数越多。
可选地,个数上限包括:1、2、4、8和16。示例性的,终端在移动速度属于低速区间时,上报参考信号时的个数上限为2;在移动速度属于中速区间时,上报参考信号时的个数上限为4;在移动速度属于高速区间时,上报参考信号时的个数上限为16。
在另一种实现中,移动速度越大,上报的参考信号个数越少。
可选地,个数上限包括:1、2、4、8和16。示例性的,终端在移动速度属于低速区间时,上报参考信号时的个数上限为8;在移动速度属于中速区间时,上报参考信号时的个数上限为4;在移动速度属于高速区间时,上报参考信号时的个数上限为2。
3、以波束管理参数包括波束测量结果中上报的测量值的比特数为例:
在波束测量结果中需要上报测量值。测量值是采用n比特的比特码字来表示的。不同比特数量对应的比特开销不同。通过减少每个参考信号的测量值上报时所占用的比特数量,能够减少信令开销。
比如,目前L1-RSRP最高的参考信号的测量值用7bit的比特码字([-140,-44]dBm范围内,每相邻两个比特码字之间相差1dB,即相邻两个比特码字之间的步长尺寸为1dB),其它参考信号的测量值是用4bit表示与最高值的差值(每相邻两个比特码字之间相差2dB,即相邻两个比特码字之间的步长尺寸为2dB)。那么为了减少信令开销,可以增加每相邻两个比特码字之间的步长尺寸,比如速度越大,步长尺寸越大,从而减少比特数。
比如,终端在移动速度属于低速区间时,使用较小的步长尺寸1确定上报时的比特码字的比特数;在移动速度属于中速区间时,使用步长尺寸2确定上报时的比特码字的比特数;在移动速度属于高速区间时,使用较大的步长尺寸3确定上报时的比特码字的比特数。
4、波束测量结果的上报周期。
不同的移动速度(区间)对应不同的上报周期。可选地,移动速度越快,上报周期越小。终端在移动速度属于低速区间时,使用较大的上报周期1;在移动速度属于中速区间时,使用上报周期2;在移动速度属于高速区间时,使用较小的上报周期3。
步骤304,根据目标波束管理参数进行波束管理。
终端根据目标波束管理参数进行波束测量,也即对波束对应的参考信号进行测量,得到波束测量结果。终端将波束测量结果上报给网络设备。网络设备根据波束测量结果确定在发送下行数据时的发送波束,网络设备向终端通知发送波束的信息。
终端根据发送波束的信息确定自身的接收波束。终端采用接收波束接收网络设备发送的下行数据。
综上所述,本实施例提供的方法,通过根据终端的移动速度,在至少两组波束管理参数中确定目标波束管理参数,根据目标波束管理参数进行波束管理。终端可以采用较小的计算量,就从至少两组波束管理参数中确定目标波束管理参数,实现逻辑较为简洁。由于不同的移动速度可对应不同的波束管理参数,因此在终端的移动速度较高时,能够采用合理的波束管理参数来减少信令开销和减小时延。
下面采用图4实施例对第一种可能的实现方式进行介绍:
图4示出了本公开另一个示例性实施例提供的波束管理方法的流程图。该 方法可以应用于图1所示的终端中,该方法包括:
步骤402,根据终端的移动速度和基础波束管理参数,生成目标波束管理参数。
终端确定基础波束管理参数,基础波束管理参数是用于生成多组波束管理参数的基础。
可选地,该基础波束管理参数是终端内置的,比如出厂设置;在另一种设计中,该基础波束管理参数是网络设备向终端配置的。
在一种设计中,将终端可能的移动速度划分为至少两个移动速度区间。以将移动速度区间中的任意两个区间为第一区间和第二区间为例:当移动速度属于第一区间时,终端根据基础波束管理参数和第一生成参数生成第一波束管理参数,作为目标波束管理参数;当移动速度属于第二区间时,终端根据基础波束管理参数和第二生成参数生成第二波束管理参数,作为目标波束管理参数。
可选地,该第一生成参数和第二生成参数是终端内置的,比如出厂设置;在另一种设计中,该第一生成参数和第二生成参数是网络设备向终端配置的。
根据波束管理参数的内容不同,示例性的实施如下:
1、以波束管理参数包括参考信号集合为例:网络设备向终端配置基础参考信号集合,该基础参考信号集合包括参考信号0、1、2、3、4、5、6、7、8、9。
终端在移动速度属于低速区间时,根据基础参考信号集合和抽样步长1,抽样生成参考信号集合1。参考信号集合1包括:参考信号0、1、2、3、4、5、6、7、8、9。
终端在移动速度属于中速区间时,根据基础参考信号集合和抽样步长2,抽样生成参考信号集合2。参考信号集合2包括:参考信号0、2、4、6、8。
终端在移动速度属于高速区间时,根据基础参考信号集合和抽样步长3,抽样生成参考信号集合3。参考信号集合3包括:参考信号0、3、6、9。
2、以波束管理参数包括上报的参考信号个数为例:网络设备向终端配置基础个数上限4,该个数上限是指终端每次进行波束测量结果的上报时,所上报的最大参考信号个数限制。
终端在移动速度属于低速区间时,根据基础个数上限4和倍数1,生成第一个数上限4。终端在移动速度属于中速区间时,根据基础个数上限4和倍数2,生成第二个数上限8。终端在移动速度属于高速区间时,根据基础个数上限4和倍数4,生成第三个数上限16。
或者,终端在移动速度属于低速区间时,根据基础个数上限4和倍数1,生成第一个数上限4。终端在移动速度属于中速区间时,根据基础个数上限4和倍数1/2,生成第二个数上限2。终端在移动速度属于高速区间时,根据基础个数上限4和倍数1/4,生成第三个数上限1。
3、以波束管理参数包括波束测量结果中上报的测量值的比特数为例:
网络设备向终端配置基础参考步长尺寸1。
比如,在移动速度属于中速区间时,使用第一生成参数1确定上报L1级别的小区参考信号接收强度(L1-Reference signal received power,L1-RSRP)最高的参考信号的测量值时的比特码字的比特数为7bit,上报其它参考信号的测量值与最高值的差值时的比特码字的比特数为4bit;在移动速度属于高速区间时,使用第二生成参数2确定上报L1-RSRP最高的参考信号的测量值时的比特码字的比特数为7bit或4bit,上报其它参考信号的测量值与最高值的差值时的比特码字的比特数为4bit或2bit。
4、波束测量结果的上报周期。
不同的移动速度(区间)对应不同的上报周期。可选地,移动速度越快,上报周期越小。网络设备向终端配置基础上报周期X。
终端在移动速度属于低速区间时,使用较大的第一生成参数2得到上报周期2X;在移动速度属于中速区间时,使用第二生成参数1得到上报周期X;在移动速度属于高速区间时,使用第三生成参数0.5得到上报周期0.5X。
步骤404,根据目标波束管理参数进行波束管理。
终端根据目标波束管理参数进行波束测量,也即对波束对应的参考信号进行测量,得到波束测量结果。终端将波束测量结果上报给网络设备。网络设备根据波束测量结果确定在发送下行数据时的发送波束,网络设备向终端通知发送波束的信息。
终端根据发送波束的信息确定自身的接收波束。终端采用接收波束接收网络设备发送的下行数据。
综上所述,本实施例提供的方法,根据终端的移动速度和基础波束管理参数,生成目标波束管理参数。由于网络设备仅需要向终端配置基础波束管理参数,以及至少两个生成参数即可,因此可以采用较小的信令开销,就能够实现终端根据终端的移动速度和基础波束管理参数确定目标波束管理参数,尽可能 大的减少信令开销和减小时延。
