车联网系统是基于D2D的一种侧行链路(Sidelink,SL)传输技术,与传统的LTE系统中通信数据通过基站接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)中定义了两种侧行传输模式:第一模式和第二模式。
第一模式:如图2所示,终端的传输资源是由基站通过下行链路(downlink,DL)分配的或者说授权的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
第二模式:如图2所示,终端可以在资源池中选取一个资源进行数据的传输。具体的,终端可以通过侦听的方式在资源池中选取传输资源,或者通过随机选取的方式在资源池中选取传输资源。
在3GPP中,D2D分成了不同的阶段进行研究,例如,其中包括车联网(V2X)研究。在版本14/15(Rel-14/15)中,车联网系统针对车车通信的场景进行了研究,其主要面向相对高速移动的车车、车人通信的业务。
在NR-V2X中,需要支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X系统中,引入了多种传输模式,模式1和模式2,其中,模式1是网络为终端分配传输资源(即上述第一模式),模式2是终端选取传输资源(即上述第二模式)。
另外,在NR-V2X中还引入了侧行功率控制,接收端终端测量SL-RSRP,并且把该SL-RSRP反馈给发送端终端,发送端终端根据其发送功率和接收端反馈的SL-RSRP,判断侧行链路的路损,根据该路损进行功率控制。
在现有的功率控制中,发送端根据侧行链路的路损确定发送功率,但是接收端的干扰状况和发送端的干扰状况可能是不同的。因此,发送端按照路损确定的发送功率,不能保证在接收端可以达到解调该数据所需的SINR,进而可能导致接收端检测数据失败。
因此,本申请实施例提出了用于传输侧行数据的方法,能够解决上述问题。
应理解,本申请实施例可以适用于车联网系统,也可以适用于任意的D2D系统。
图3为本申请实施例提供的一种用于传输侧行数据的方法200的示意性流程图。该方法200可以由任意一个终端设备执行,为了便于描述,这里将该终端设备称为第一终端设备,例如,该第一终端设备可以为如图1所示的终端设备。如图3所示,该方法200包括:S210,第一终端设备接收功率指示信息,该功率指示信息用于指示功率调整值;S220,该第一终端设备按照该功率调整值,调整向第二终端设备发送侧行数据或第一侧行链路参考信号时的发送功率。

具体地,第一终端设备采用初始发送功率向第二终端设备发送第二侧行链路参考信号,当第一终端设备和第二终端设备进行首次数据传输时,该初始发送功率可以为第一终端设备采用以下方式中的任意一种方式确定的:该初始发送功率为第一终端设备的最大发送功率;该初始发送功率为网络设备为该第一终端设备配置的,例如可以为该网络设备为第一终端设备配置的最大发送功率;该初始发送功率还可以为第一终端设备根据当前的信道拥塞率(Channel Busy Ratio,CBR)确定的;该初始发送功率还可以为第一终端设备根据下行链路的路损确定的发送功率。应理解,该初始发送功率是该第一终端设备在获取该功率调整值之前采用的发送功率。
该第二终端设备接收该第一终端设备发送的该第二侧行链路参考信号,则可以确定该第二侧行链路参考信号的相关接收参数。例如,第二终端设备可以根据该第二侧行链路参考信号,确定功率参数信息,其中,该功率参数信息可以包括该第二侧行链路参考信号的以下信息中的至少一个:第二侧行链路参考信号的SL-RSRP、第二侧行链路参考信号的侧行链路参考信号接收质量(Sidelink Reference Signal Received Quality,SL-RSRQ)、第二侧行链路参考信号的侧行链路参考信号强度指示(Sidelink Received Signal Strength Indicator,SL-RSSI)以及接收第二侧行链路参考信号时的SINR。

应理解,本申请实施例中的功率调整值可以为具体的某个数值,或者,该功率调整值还可以包括功率调整范围,第一终端设备可以基于该功率调整范围确定发送功率,本申请实施例并不限于此。
例如,第二终端设备可以通过测量确定第一终端设备发送的第二侧行链路参考信号的SINR(记为SINR_rx);再根据期望接收到的SINR_target,确定第一终端设备需要调整的功率值ΔP=SINR_target–SINR_rx,并且将该调整值ΔP作为功率调整值发送给第一终端设备。

例如,以该功率调整值为需要调整的数值ΔP为例,该功率指示信息可以包括一个索引值,通过该索引值可以确定与之对应的功率调整值。其中,该功率指示信息可以占用一个或者两个比特位。例如,这里假设该功率指示信息占用2比特,则该功率指示信息能够指示的功率调整值与对应索引之间的关系可以如表1所述。
表1
功率指示信息的取值 调整功率值(dB)
0 2
1 0
2 -1
3 -2
其中,调整功率值为0dB表示功率不变,功率值大于0dB表示提升发送功率,功率值小于0dB表示降低发送功率。
可选地,索引值和调整功率值之间的对应关系可以是预定义的、网络设备配置的,或者也可以是第一终端设备与第二终端设备所在通信组中的组头终端配置的。
又例如,该功率指示信息包括功率调整值为需要调整的数值ΔP,第一终端根据该功率调整值ΔP以及上一次使用的发送功率确定调整后的发送功率。具体的,例如,该功率调整值ΔP是6dB,第一终端上一次使用的发送功率是15dB,则调整后的发送功率为6dB+15dB=21dB,即第一终端以21dB发送侧行数据或侧行参考信号。
又例如,该功率指示信息包括功率调整值还可以为调整之后的功率,即该功率调整值即为第一终端的发送功率。具体的,例如,该功率调整值是18dB,第一终端获取该功率指示信息,即可确定下一次发送侧行数据或侧行信号的发送功率为18dB。
可选地,在S211中,第二终端设备向第一终端设备发送功率指示信息,该功率指示信息可以为功率控制指示信息(Transmission Power Control,TPC);该功率指示信息可以承载在第二终端设备向第一终端设备发送的侧行链路控制信息(Sidelink Control Information,SCI)中。可选地,在S211中,第二终端设备向第一终端设备发送功率指示信息可以承载在第二终端设备向第一终端设备发送的PSSCH中,例如,通过媒体接入层(Media Access Control,MAC)控制单元(Control Element,CE)或者侧行链路无线资源控制信令(Sidelink Radio Resource Control,SL-RRC)承载。

另外,第一终端设备基于该功率调整值的含义,确定发送功率。例如,若该功率调整值为第一终端设备确定发送功率时所需的调整数值,则第一终端设备根据该功率调整值,增加或者减少当前功率值以获得发送功率;或者,该功率指示信息指示的功率调整值也可以为调整之后的发送功率的值,则第一终端设备可以将该功率调整值确定为发送侧行数据或侧行参考信号使用的发送功率值。
在本申请实施例中,第一终端设备采用初始发送功率发送第二侧行链路参考信号,对应的,在该S231中,该第一终端设备可以根据确定的功率调整值,调整该初始发送功率,例如增加或者减少该初始发送功率,或者调整该初始发送功率为功率指示信息指示的功率调整值,并采用调整后的发送功率,向第二终端设备发送侧行数据或者第一侧行链路参考信号。因此,在本申请实施例中,接收端终端根据测量的SINR以及期望的SINR,确定功率调整值,并且指示发送端终端进行功率调整,从而能够保证接收端终端接收侧行数据或者侧行信号时获取期望的SINR。

可选地,第一终端设备向第三终端设备发送PHR,该PHR可以表示该第一终端设备的发送功率能够增大或者减小的数值范围,以便于第三终端设备可以进一步根据该信息确定第一终端设备的功率调整值。
应理解,对于第三终端设备确定的功率调整值,与S211类似,在S213中,该第三终端设备通过向第一终端设备发送的功率指示信息指示该功率调整值,该功率调整值可以为具体的某个数值,或者,该功率调整值还可以包括功率调整范围,第一终端设备可以基于该功率调整范围确定发送功率,本申请实施例并不限于此。
另外,与S211类似,在S212中,本申请实施例中的功率指示信息用于指示功率调整值,可以包括以下情况中的任意一种:该功率指示信息可以包括该功率调整值的索引;或者,该功率指示信息也可以包括该功率调整值本身;或者,该功率指示信息也可以包括该功率调整值量化后的数值。另外,该功率指示信息指示的该功率调整值可以为第一终端设备确定发送功率时所需的调整数值,即第一终端设备根据该功率调整值,增加或者减少当前功率值以获得发送功率;或者,该功率指示信息指示的功率调整值也可以为调整之后的发送功率的值,即第三终端设备通过该功率指示信息指示第一终端设备发送侧行数据或侧行参考信号使用的发送功率值,本申请实施例并不限于此。
如图6所示,对应图3中的方法200的S220,该方法200可以包括:S223,确定功率调整值,即第一终端设备根据第三终端设备发送的功率指示信息,确定功率调整值。
具体地,根据S213中的描述,该功率指示信息指示功率调整值的方式可以包括多种情况中的任意一种,因此,在S222中,第一终端设备可以根据该功率指示信息的指示方式,确定对应的功率调整值。例如,该功率指示信息可以包括该功率调整值的索引,则第一终端设备可以根据功率调整值和索引的对应关系,确定功率指示信息包括的索引值对应的功率调整值。
再例如,若该功率指示信息也可以包括该功率调整值量化后的数值,则第一终端设备可以通过量化处理,确定对应的功率调整值。

具体地,若该功率调整值为某个具体数值,则第一终端设备可以根据该数值确定发送功率;若该功率调整值为某个取值范围,则第一终端设备可以在该取值范围内选择合适的数值以确定发送功率,本申请实施例并不限于此。
另外,第一终端设备基于该功率调整值的含义,确定发送功率。例如,若该功率调整值为第一终端 设备确定发送功率时所需的调整数值,则第一终端设备根据该功率调整值,增加或者减少当前功率值以获得发送功率;或者,该功率指示信息指示的功率调整值也可以为调整之后的发送功率的值,则第一终端设备可以将该功率调整值确定为发送侧行数据或侧行参考信号使用的发送功率值。
在本申请实施例中,第一终端设备采用初始发送功率发送第四侧行链路参考信号,对应的,在该S233中,该第一终端设备可以根据确定的功率调整值,调整该初始发送功率,例如增加或者减少该初始发送功率,或者调整该初始发送功率为功率指示信息指示的功率调整值,并采用调整后的发送功率,向第二终端设备发送侧行数据或者侧行信号
因此,在本申请实施例中,组头终端根据接收端终端或者发送端终端上报的侧行链路的路损、SL-RSRP、SL-RSRQ、SL-RSSI、SINR等信息,配置发送端的发送功率,保证接收端终端接收侧行数据或者侧行信号时获得期望的SINR。
上文中结合图3至图6,详细描述了根据本申请实施例的用于传输侧行数据的方法200,下面将结合图7,描述本申请实施例的另一用于传输侧行数据的方法。
图7示出了根据本申请实施例的用于传输侧行数据的方法300的示意性流程图。如图7所示,该方法300包括:S310,发送功率参数信息。第一终端设备接收第二终端设备发送的功率参数信息,该功率参数信息包括第二终端设备接收第一侧行链路参考信号时的参数。其中,该第一侧行链路参考信号可以指任意侧行链路参考信号。
应理解,本申请实施例中的第一终端设备和第二终端设备可以指任意两个进行侧行链路传输的终端设备,例如,该第一终端设备或中第二终端设备可以指如图1和图2所示的任意一个终端设备,本申请实施例并不限于此。
应理解,该功率参数信息可以包括以下第一侧行链路参考信号的信息中的至少两个:第一侧行链路参考信号的SL-RSRP、该第一侧行链路参考信号的SL-RSRQ、该第一侧行链路参考信号的SL-RSSI和该第一侧行链路参考信号的SINR。
具体地,该方法300还包括:该第一终端设备采用初始发送功率向该第二终端设备发送该第一侧行链路参考信号,以便于该第二终端设备根据该第一侧行链路参考信号确定该功率参数信息。
应理解,该第一侧行链路参考信号可以为任意侧行链路参考信号,例如,该第一侧行链路参考信号可以为PSCCH-DMRS;或者,该第一侧行链路参考信号还可以为PSSCH-DMRS;或者,该第一侧行链路参考信号还可以为SL CSI-RS,但本申请实施例并不限于此。
可选地,本申请实施例中的该功率参数信息可以承载在PSSCH中,即第二终端设备可以通过该PSSCH发送该功率参数信息。可选地,本申请实施例中的该功率参数信息可以承载在PSCCH中,即第二终端设备可以通过该PSCCH承载的SCI发送该功率参数信息
应理解,如果第一终端设备仅获取第二终端设备接收第一侧行链路参考信号的第一SL-RSRP,第一终端设备据此调节的发送功率只能通过弥补路损带来的损失,即只能保证接收端的接收功率,但是不能保证接收端能够具有解调数据所需的SINR,因为发送端第一终端设备并不知道接收端的干扰水平。
因此,第一终端设备获取的第二终端设备发送的功率参数信息包括第一SL-RSRP、第一SL-RSRQ、第一SL-RSSI和第一SINR中的至少两个。
对应的,如图7所示,该方法300还包括:S320,确定功率调整值。该第一终端设备根据该功率参数信息,确定功率调整值。具体地,该第一终端设备根据该功率参数信息,确定该第二终端设备接收该第一侧行链路参考信号时的信干噪比SINR;该第一终端设备根据该信干噪比SINR,确定该功率调整值。
具体地,第一终端设备可以根据第二终端设备发送的功率参数信息,可以计算出第二终端设备接收第一侧行链路参考信号时的SINR,再根据待传输数据的调制与编码策略(Modulation and Coding Scheme,MCS)等级,以及接收端第二终端设备解调该MCS对应的侧行数据所需的SINR,可以确定出第一终端设备的发送功率的调整值。
例如,第一终端设备以功率P1发送侧行数据;第一终端设备根据第二终端设备反馈的SL-RSRP、SL-RSSI以及SL-RSRQ,可以计算出来的在接收端第二终端设备接收第一侧行链路参考信号时的SINR(记为SINR_rx)为10dB。另外,第一终端设备的待传输数据的MCS等级为15,接收端第二终端设备以99%的成功检测概率检测该侧行数据所需的SINR(记为SINR_req)为15dB,则第一终端设备需要增大发送功率至P2,即P2=P1+5dB,即功率调整值为5dB。
如图7所示,该方法300还包括:S330,发送侧行数据。该第一终端设备按照该功率调整值,调整向该第二终端设备发送侧行数据或第二侧行链路参考信号时的发送功率。具体地,该第一终端设备按照该功率调整值,调整向第二终端设备发送第一侧行链路参考信号时的初始发送功率;该第一终端设备采用调整后的发送功率向该第二终端设备发送该侧行数据或者侧行信号,例如该侧行信号可以为任意侧 行链路参考信号。
因此,在本申请实施例中,接收端终端将SL-RSRP、SL-RSRQ、SL-RSSI、SINR等信息发送给发送端终端,发送端终端可以确定接收端终端接收侧行数据时的SINR,并且据此调整发送功率,保证接收端终端接收侧行数据时获得期望的SINR。
应理解,本申请实施例中的方法200和方法300可以相互独立使用,或者也可以相互结合使用。例如,接收端第二终端设备向发送端第一终端设备发送的功率指示信息包括SL-RSRP、SL-RSSI、SL-RSRQ以及功率调整值。则发送端第一终端设备根据SL-RSRP、SL-RSSI或者SL-RSRQ确定接收端的SINR,通过功率调整值可以确定需要调整的功率大小,但本申请实施例并不限于此。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
