技术领域

背景技术
在相关新空口(New Radio,NR)旁链路(Sidelink,也称直接通信链路)标准化进程中,是支持组播混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)功能的,对于组播通信来说,只要发送端收到来自接收端的确认失败(Negative acknowledgment,NACK)反馈,都要进行重传。
这种前提下,可能存在一些问题,组播通信中,远距离的用户也能接收到该数据包,而且远距离的用户解码成功率随着距离的增加会降低,这样会导致这些用户反馈NACK,从而导致发端用户进行一些不必要的重传。这些不必要的重传会对其他的发包用户产生额外的干扰,降低系统性能的同时还增加了反馈开销。所以提出了组播中的HARQ反馈是基于收发端用户距离的反馈,提出的解决方案中有基于全球导航卫星系统(GNSS)进行地理区域(zone)的划分来判断收发端距离的方案,但是这种解决方案中可能会存在收不到GNSS信号的情况,在此种情况下,终端不知如何进行HARQ反馈。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开进行详细描述。
在进行本公开的一些实施例的说明时,首先对下面描述中所用到的一些概念进行解释说明。
相关的新空口(New Radio,NR)旁链路(Sidelink)中,支持单播、组播和广播通信。其中,组播和单播通信是支持混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)的。对于组播通信来说,是一对多的通信方式,在HARQ功能开启的状态下,组内任意一个接收端用户反馈NACK都会导致HARQ重传。对于距离的较远的接收用户,很容易因为信道质量较差、建筑遮挡等因素导致不能正确接收,从而反馈NACK导致重传。但是远距离的用户是否接收正确对整体系统性能的影响不大,并且发端用户也不会太关心远距离用户的接收成功率,所以这种情况的HARQ反馈往往是没有必要的,这种反馈反而会引起一些不必要的重传,对于其他正在发包的发送用户来说也增加了干扰,远距离用户的反馈也增加了不必要的反馈开销,会降低系统性能。
所以基于一定范围的HARQ反馈机制被提出了,这种机制可以是基于收发端用户距离的,也可以是基于参考信号接收功率(Reference signal receiving power,RSRP)测量,具体采用哪一种还是两者都采用都没有确定。但是如何来确定收发端用户的距离还没有确定的方案,这是现存的一个问题。
在长期演进(Long Term Evolution,LTE)车到外界(Vehicle-to-Everything,V2X)中,高层对地理区域的划分有一套规则,能将全地图的地理位置划分为很多地理区域(zone),每个zone会赋予一个id号。每个zone的长宽、长宽维度上的复用因子都是可以高层配置的。长宽维度的复用因子指的是在长宽维度上zone id不同的数量,举个例子,若长维度上的复用因子为4,则在长的维度上只可能存在四个不同的zone id号(比如:0,1,2,3)。用户设备(User Equipment, UE,也称终端)通过这套规则以及全球导航卫星系统(GNSS)定位的自己的经纬度信息能够计算得到自己的zone id。但是高层定义的zone id只是和资源池相关联。物理层对于地理区域划分规则以及利用划分规则进行HARQ重传的规则流程还没有定义。
LTE高层对于zone的划分具体的计算规则(规则A)如下:
A11、假设一个UE的经纬度分别为(x,y);
A12、一个zone区域长和宽分别为L和W;
A13、在经度和维度的复用粒度为A和B;
A14、可分别计算该UE在经纬度的id号(x1,y1):x1=mod(floor(x/L;),A);y1=mod(floor(y/W),B)
A15、最终该UE的zone id为:id=y1*A+x1。
提出的解决方案中有基于全球导航卫星系统(GNSS)进行地理区域(zone)的划分来判断收发端距离的方案,正是LTE中高层对地理区域的划分方式。但是这种解决方案中可能会存在收不到GNSS信号的情况,在此种情况下,终端不知如何进行HARQ反馈。
本公开针对当基于GNSS进行zone的划分来区分收发端距离时,若终端不能接收到GNSS信号,造成不能保证正常通信的问题,提供一种信息发送、接收方法、终端及控制节点。
如图1所示,本公开的一些实施例提供一种信息发送方法,应用于发送端,包括:
步骤101,在发送端无法获取全球导航卫星系统GNSS定位信息时,向接收端发送第一信息;
其中,所述第一信息用于辅助所述接收端判断是否进行混合自动重传请求(HARQ)反馈;
其中,所述第一信息包括以下至少一项:参考信号接收功率(RSRP)门限指示、所述发送端的地理区域标识、通信范围指示和HARQ不可用的指示。
需要说明的是,在发送端无法获取GNSS定位信息时,发送端向接收端发送辅助接收端判断是否进行HARQ反馈的第一信息,以保证在发送端无法获取GNSS定位信息、接收端无法获取GNSS定位信息、或收发端都无法获取GNSS定位信息时,收发端之间也能进行正常的HARQ反馈。
需要说明的是,所述第一信息包括的内容主要分为以下几种情况:
M11、所述第一信息包括:RSRP门限指示;
M12、所述第一信息包括:所述发送端的地理区域标识和通信范围指示;
M13、所述第一信息包括:RSRP门限指示、所述发送端的地理区域标识和通信范围指示;
M14、所述第一信息包括:HARQ不可用的指示。
下面分别从不同的情况对本公开的一些实施例进行具体说明如下。
情况一、所述第一信息包括:RSRP门限指示
在此种情况下,所述RSRP门限指示包括第一目标码点,且所述第一目标码点满足以下至少一项:
H11、对应一个RSRP门限;
H12、对应一个RSRP门限到RSRP参考值的调整步长;
需要说明的是,因RSRP参考值为接收端和发送端都知道的,接收端在获取到调整步长后,便可以根据该调整步长计算得到对应的RSRP门限。
具体地,在此种情况下,所述第一信息中包括第四指示域,所述第四指示域用于指示RSRP门限大于RSRP参考值或小于RSRP参考值。
需要说明的是,该第四指示域为可选地,当存在该第四指示域时,RSRP门限的选择依据该第四指示域进行选择,而当不存在该第四指示域时,即第一目标码点对应一个RSRP门限到RSRP参考值的调整步长时,可以约定RSRP参考值为RSRP门限的最大值或最小值,此时只需要知道调整步长就能计算得到具体地RSRP门限。
这里需要说明的是,所述第一目标码点为至少一个码点中的一个,且所述至少一个码点中每个码点对应一个RSRP门限或一个RSRP门限到RSRP参考值的调整步长。
在每个码点对应一个RSRP门限时,例如,RSRP门限有四个码点,分别为00、01、10、11。每个码点对应的RSRP门限分别为-70dBm、-67dBm、-64dBm和-61dBm。
在每个码点对应一个RSRP门限到RSRP参考值的调整步长时,例如RSRP参考值为-70dBm,步长为3dB,假设四个码点对应的步长数量分别为0、1、2、3,意味着到参考值的量值分别为0dBm、3dBm、6dBm和9dBm,对应的RSRP 门限值分别为-70dBm、-67dBm、-64dBm和-61dBm。另一种方式就是需要额外的一比特指示RSRP门限是大于参考值还是小于参考值,假设这一比特位0时表示大于参考值,为1时表示小于参考值。在上述例子中,若这额外的一比特为1时,对应的RSRP门限指示为01,则对应指示的RSRP门限为-67dBm。
进一步需要说明的是,此种情况下,RSRP门限指示所指示的RSRP门限通过以下至少一项确定:
H21、通信范围;
需要说明的是,在此种情况下,一个RSRP门限对应一个预设范围内的通信范围,也就是说,通信范围在一定范围内对应一个RSRP门限。
例如,假设RSRP门限对应的码点有四个,分别为00、01、10、11,分别对应的门限值为-70dB、-73dB、-76dB和-79dB。那么当通信范围在[0,50]区间范围内时,确定的RSRP门限值为-70dB,对应的码点为00;当通信范围在[50,150]区间范围内时,确定的RSRP门限值为-73dB,对应的码点为01;当通信范围在[150,300]区间范围内时,确定的RSRP门限值为-76dB,对应的码点为10;当通信范围在[300,500]区间范围内时,确定的RSRP门限值为-79dB,对应的码点为11。
H22、第一信息的扰码;
需要说明的是,在此种情况下,一个RSRP门限对应至少一个扰码,也就是说,一个或多个扰码对应一个RSRP门限。
例如,假设控制信息的扰码一共有八个,分别用字母A-H表示,那么由扰码确定RSRP门限的具体方式为:A和B确定RSRP门限值为-70dB,对应的码点为00、C和D确定RSRP门限值为-73dB,对应的码点为01、E和F确定RSRP门限值为-76dB,对应的码点为10、G和H确定RSRP门限值为-79dB,对应的码点为11。
H23、参考信号(RS)序列;
需要说明的是,在此种情况下,一个RSRP门限对应至少一个RS序列,也就是说,一个或多个RS序列对应一个RSRP门限。
例如,假设RS序列有四个,分别为A、B、C、D,则由RS确定RSRP的具体实现方式为:A确定RSRP门限值为-70dB,对应的码点为00、B确定RSRP门限值为-73dB,对应的码点为01、C确定RSRP门限值为-76dB,对应的码点 为10、D确定RSRP门限值为-79dB,对应的码点为11。
进一步还需要说明的是,所述RSRP门限指示所指示的RSRP门限还通过以下至少一项确定:
H24、发送端的运动速度;
H25、发送端接收的信号强度指示(RSSI)的测量值;
H26、发送端的发射功率;
H27、发送端的服务质量(QoS)的业务特性;
该业务特性可以为业务时延、优先级、调制方式、码率、待传数据量、可靠性、吞吐量、占用带宽等。
还需要说明的是,若至少两个数据包复用在一个传输块的情况下,所述RSRP门限指示满足以下至少一项:
H31、在至少两个数据包均对应第一RSRP门限时,所述RSRP门限指示用于指示第一RSRP门限;
也就是说,当至少两个数据包均对应相同的RSRP门限时,该所述RSRP门限指示用于指示的就是至少两个数据包均对应的RSRP门限。
H32、当至少两个数据包对应的RSRP门限不完全相同时,所述RSRP门限指示用于指示至少两个数据包对应的RSRP门限中的最小值;
H33、当至少两个数据包对应的RSRP门限不完全相同时,所述RSRP门限指示用于指示至少两个数据包对应的RSRP门限中的最大值;
H34、当至少两个数据包对应的RSRP门限不完全相同时,所述RSRP门限指示用于指示至少两个数据包对应的RSRP门限中出现次数最多的RSRP门限;
也就是说,这种情况下,会统计每种RSRP门限出现的次数,将出现次数最多的RSRP门限作为RSRP门限指示的内容。
需要说明的是,若出现次数最多的RSRP门限对应多个值,则在出现次数最多的RSRP门限中选择最大值、最小值或随机选择一个值。
H35、当至少两个数据包对应的RSRP门限不完全相同时,所述RSRP门限指示用于指示第二RSRP门限,所述第二RSRP门限为至少两个数据包对应的RSRP门限中与至少两个数据包对应的RSRP门限的平均值的差值最小的RSRP门限;
例如,当至少一个通信范围中包括:-20dB、-50dB、-80dB、-100dB四个 值时,这四个值的平均值为-62.5dB,则选择与-62.5dB最接近的-50dB作为RSRP门限指示所指示的RSRP门限。
H36、当至少两个数据包对应的RSRP门限不完全相同时,所述RSRP门限指示用于指示第三RSRP门限,所述第三RSRP门限与数据包对应的服务质量(QoS)参数相关联;
H37、当至少两个数据包对应的RSRP门限不完全相同时,所述RSRP门限指示用于指示第一预设RSRP门限。
这需要说明的是,当至少两个数据包对应的RSRP门限不完全相同时,也就是说发送端不期望出现这种情况,在此时,发送端所发送的第一信息中不会携带RSRP门限指示,第一信息会携带其他的信息,例如,携带上述M12的信息或携带上述M14的信息。
还需要说明的是,在此种情况下,接收端接收到该第一信息后,执行以下动作:判断接收端是否能够获取全球导航卫星系统GNSS定位信息;根据所述判断结果以及所述第一信息,确定是否进行HARQ反馈。
需要说明的是,在此种情况下,不管所述判断结果为接收端能够获取GNSS定位信息或接收端不能够获取GNSS定位信息,接收端都需要进行RSRP测量,在测量结果大于所述RSRP门限指示所指示的RSRP门限时,进行HARQ反馈,在测量结果小于或等于所述RSRP门限指示所指示的RSRP门限时,则不进行HARQ反馈。
情况二、所述第一信息包括:所述发送端的地理区域标识和通信范围指示
需要说明的是,在此种情况下,因发送端无法获取到GNSS定位信息,则发送端不能根据定位信息确定得到自身当前的地理区域标识,在此种情况下,发送端采用以下方式中的至少一项进行自身的地理区域标识的获取:
I11、根据存储的发送端的历史地理区域标识,确定发送端的地理区域标识;
需要说明的是,为了实现此种方式,发送端采用如下情况中的一项:
I111、将最近一次使用的地理区域标识,确定为发送端的地理区域标识;
I112、统计每个地理区域标识在目标时间段内出现的次数,将出现次数最多的地理区域标识,确定为发送端的地理区域标识;
需要说明的是,若存在多个地理区域标识出现的次数最多,则在所述多个地理区域标识中随机选择一个,作为发送端的地理区域标识。
进一步需要说明的是,该目标时间段的长度由协议预定义、控制节点配置或其他终端指示。
I12、根据发送端的移动速度和移动方向,确定发送端的地理区域标识;
I13、根据其他终端的地理区域标识,确定发送端的地理区域标识;
例如,当接收端接收到附近其他终端发送的控制信息中携带的地理区域标识时,可以选择信号最强的控制信息的地理区域标识,或选择单播连接对端的地理区域标识作为自身的地理区域标识。
I14、根据高层信息获取发送端的地理区域标识;
例如,接收端根据获取其他终端广播的信息(例如basic safety消息等),在该信息中获取相关信息来确定自身的地理区域标识。
I15、从控制节点获取发送端的地理区域标识;
需要说明的是,为了实现此种方式,发送端采用如下方式:发送定位信息请求给控制节点;接收所述控制节点反馈的发送端的地理区域标识。
具体地,所述定位信息请求通过以下至少一项上报:
I21、物理旁链路控制信息(SCI);
I22、调度请求(SR);
I23、缓冲区状态报告(BSR);
I24、上行控制信息(UCI);
I25、物理上行共享信道(PUSCH);
I26、媒体接入控制层控制单元(MAC CE)。
进一步地,所述通信范围指示中包括一个第二目标码点;
其中,所述第二目标码点为至少一个码点中的一个,且所述至少一个码点中每个码点对应一个通信范围。
进一步地,所述发送端的地理区域标识用一组码点中的一个进行指示,且一组码点中的每一个码点对应一个地理区域标识。
还需要说明的是,在此种情况下,接收端接收到该第一信息后,执行以下动作:判断接收端是否能够获取全球导航卫星系统GNSS定位信息;根据所述判断结果以及所述第一信息,确定是否进行HARQ反馈。
需要说明的是,在此种情况下,终端的具体实现方式为:根据所述发送端的地理区域标识、接收端的地理区域标识和通信范围指示,确定是否进行HARQ 反馈。

具体地,该第一距离为接收端和发送端之间距离的最大值,该第二距离为接收端和发送端之间距离的最小值。
I422、根据接收端的定位信息和所述发送端所在地理区域的第一参考点,获取第一目标距离,若所述第一目标距离小于所述发送端和接收端之间的地理距离,则确定进行HARQ反馈;

还需要说明的是,上述的情况一和情况二是二者择其一的,也就是说,第一信息只能选择上述的一者进行发送,这里需要说明的是,RSRP门限指示可以采用独立的指示域进行指示。
进一步地,当所述RSRP门限指示所指示的RSRP门限和所述通信范围指示所指示的通信范围均为一个协议预定义的值,所述第一信息中包括第一指示域,所述第一指示域用于指示RSRP门限或通信范围;例如,协议可以预定义一个RSRP门限和一个通信范围,比如该RSRP门限为-70dBm,通信范围指示值为100m。在第一信息中携带一比特可以指示,例如当这一比特值为0时,则代表为RSRP门限,对应-70dBm;若这一比特值为1,则表示为通信范围,对应100m。

I51、所述第二指示域对应至少一个码点,所述至少一个码点中的第一部分码点用于指示RSRP门限指示,所述至少一个码点中的第二部分码点用于指示通信范围指示;
例如,假设一个指示域既可以指示RSRP门限又可以指示通信范围,并且这个指示域存在三个比特。其中000、001、010、011四个码点指示的RSRP门限值,例如分别对应-70dBm、-67dBm、-64dBm和-61dBm;100、101、110、111四个码点指示的是通信范围,例如分别对应50m、100m、200m和400m的通信范围。

需要说明的是,该第三指示域可以为重用已有的指示域,比如在地理区域标识的指示域中对应一个特殊码点,例如,假设一个指示域A既可以指示RSRP门限又可以指示通信范围,并且这个指示域存在两个比特。其中00、01、10、11四个码点指示的RSRP门限值分别为-70dBm、-67dBm、-64dBm和-61dBm;指示的通信范围值分别为50m、100m、200m和400m;具体地,同一个码点代表什么意思由另一个指示判定,例如,地理区域标识的指示域中的一个特殊码点0000,假设再第一信息中携带的地理区域标识指示为0000,则说明,指示域A指示的是RSRP门限信息,若地理区域标识的指示域中的指示不是特殊码点0000,指示域A指示的信息就是通信范围。
还需要说明的是,该第三指示域也可以为第一信息中新增的指示域,例如,假设一个新增指示域A既可以指示RSRP门限又可以指示通信范围,并且这个指示域存在两个个比特,其中00、01、10、11四个码点指示的RSRP门限值分别为-70dBm、-67dBm、-64dBm和-61dBm;指示的通信范围值分别为50m、100m、200m和400m;具体地,同一个码点代表什么意思由另一个指示判定,定义额外的1比特指示,当该比特码点为0时,则说明,指示域A指示的是RSRP门限信息,若该比特码点值为1,指示域A指示的信息就是通信范围。
情况三、所述第一信息包括:RSRP门限指示、所述发送端的地理区域标识 和通信范围指示
需要说明的是,在此种情况下,第一信息中必须要包括:信息可靠度指示,且RSRP门限指示需要用独立的指示域进行指示,以与发送端的地理区域标识和通信范围指示进行区分。
具体地,该信息可靠度指示用于辅助接收端基于目标信息进行HARQ反馈;
其中,所述目标信息为:所述RSRP门限指示,或所述目标信息为:所述发送端的地理区域标识和通信范围指示。
进一步需要说明的是,所述信息可靠度指示用一个第三目标码点进行指示;
其中,所述第三目标码点为至少一个码点中的一个,且所述至少一个码点中每个码点对应一个可靠度取值。
例如,假如对应四个码点,分别为00、01、10、11,四个码点对应的可靠度信息可以是一组0到1的值,越靠近1表示可靠度越高。比如说,四个码点对应的可靠度值可以是0.25、0.5、0.75和1。
还需要说明的是,所述信息可靠度指示所指示的可靠度取值由所述发送端的地理区域标识的获取方式确定。
还需要说明的是,在此种情况下,接收端接收到该第一信息后,执行以下动作:判断接收端是否能够获取全球导航卫星系统GNSS定位信息;根据所述判断结果以及所述第一信息,确定是否进行HARQ反馈。
需要说明的是,在此种情况下,终端的具体实现方式为:根据所述发送端的地理区域标识、接收端的地理区域标识和通信范围指示,确定是否进行HARQ反馈。

其中,所述目标信息为:所述RSRP门限指示,或所述目标信息为:所述发送端的地理区域标识和通信范围指示。
需要说明的是,在确定得到目标信息后,接收端在依据该目标信息,确定是否进行HARQ反馈,具体地实现方式可参见情况一和情况二,在此再赘述。
情况四、所述第一信息包括:HARQ不可用的指示
需要说明的是,该HARQ不可用的指示采用第一信息中的第五指示域进行 指示。
可选地,该第五指示域可以重用现有的指示域,例如,在携带地理区域标识的指示域中设置一个特殊码点(例如1111),指示HARQ不可用的指示;可选地,该第五指示域也可以用额外的新增的一个指示域,该指示域用一比特表示,若第一信息中携带该一比特,则说明第一信息中携带HARQ不可用的指示,表示HARQ不可用,接收端无需进行HARQ反馈。
具体地,接收端在接收到携带有HARQ不可用的指示的第一信息后,确定不进行HARQ反馈。
