新一代的新型互联网应用的不断涌现对于无线通信技术提出了更高的要求,驱使无线通信技术的不断演进以满足应用的需求。车联网通信是目前蜂窝无线通信网络的发展所需支持的应用之一。
车联网通信(vehicle to everything,V2X)包括车对车(vehicle to vehicle,V2V)业务、车对路边设备(vehicle to Infrastructure,V2I)业务和车对人(vehicle to pedestrian,V2P)。通过支持车载设备间(V2V),车载设备和路边设备间(V2I),车载设备和手持设备间(V2P)的通信,车联网可以有效提升交通安全,改善交通效率以及丰富人们的出行体验。利用已有的蜂窝通信技术支持车联网通信可以有效利用现有基站部署,减少设备开销,也更有利于提供具有服务质量(Quality of Service,QoS)保证的服务,满足车联网业务的需求。因此,在长期演进(Long Term Evolution,LTE)Rel-14/15中提供了蜂窝网络对于车联网V2x通信的支持,即C-V2x(cellular based V2x)。在C-V2x中车载设备和其他设备之间的通信可以通过基站以及核心网进行中转,即利用原有蜂窝网络中终端设备和基站之间的通信链路进行通信(上行/下行通信);也可以直接通过设备之间的直连链路进行通信(sidelink通信)。与Uu接口通信相比,sidelink通信具有时延短,开销小等特点,非常适合用于车载设备和地理位置接近的其他周边设备直接的通信。
LTE中的V2x sidelink通信只能支持一些基础的安全方面的V2x应用,如交换协作感知消息(Cooperative Awareness Messages,CAM)或分散式环境通知消息(Decentralized Environmental Notification Message,DENM)等基础安全信息(Basic Safety Message,BSM),进行语音广播通信等。近来随着自动驾驶等技术的发展,为了支持新的V2x业务,对于V2x技术的性能又提出了新的要求。利用第五代移动通信(the 5th generation mobile communication,5G),也称新空口(New Radio,NR)技术支持新的V2x通信服务和场景已经被3GPP计划为Rel16的一项重要内容。3GPP SA1(Service Requirement)工作组已经设立了一些新的V2x通信需要满足的业务需求,包括车队管理(Vehicles Platooning),感知扩展(Extended Sensors),先进驾驶(Advanced Driving),和远程驾驶(remote driving)。总体来说,NR V2x sidelink需要提供更高的通信速率,更短的通信延时,更可靠的通信质量。
NR上下行设计中引入了带宽部分(BandWidth Part,BWP)的概念,一个BWP指在给定载频上给定子载波间隔下的连续频域资源块(resource block, RB)。在NR上行设计中,每个用户设备在给定载波上可以被配置最多四个上行BWP,但在同一时间只能激活其中一个上行BWP。基站端可以通过下行动态信令对BWP进行激活和切换。
在NR V2x Rel16中,与上行BWP和下行BWP类似,定义了用户设备进行sidelink发送和接收使用的sidelink BWP。为了保证相同任意用户之间可以收发数据,在sidelink上发送和接收数据使用相同的BWP,每个车联网用户只能被配置一个sidelink BWP,并假设所有的车联网用户设备被配置的BWP相同。在sidelink BWP上进一步规定了直连通信资源池作为直连通信可以使用的时间和频率资源的集合。
在LTE V2x中,直连通信传输只能使用上行传输时间频率资源。如果是时分双工(Time Division Duplexing,TDD)系统,直连通信的时频资源在上行子帧中;如果是频分双工(Frequency Division Duplexing,FDD)系统,直连通信的时频资源在上行频带中。请参考图1,其示出了本公开一示例性实施例提供的LTE中直连通信的资源池配置示意图。
在NR TDD系统中,上下行的时间资源分配由slot format(时隙格式)来决定。时隙格式包括下行时域符号(DL symbol),上行时域符号(UL symbol)和灵活时域符号(flexible symbol)。
灵活符号一般用于下行和上行之间的切换保护时间,非蜂窝通信或为未来的资源使用预留,在特定情况下,也可以被转化为上行或者下行符号进行上行/下行通信。系统可以通过公共的(UE common)半静态下行信令或针对特定用户的(UE specific)半静态下行信令对时隙格式进行配置。公共配置的时隙格式中的灵活符号可以被针对特定用户的配置更改为上行或下行符号。系统也可以通过下行动态信令对半静态配置的时隙格式中的灵活时域符号再进行指示,将灵活符号更改为上行或下行符号。例如半静态公共配置中的某个slot中的14个符号都是灵活符号,通过针对特定用户的无线资源控制(Radio Resource Control,RRC,RRC)信令可以将这14个符号指示为DDXXXXXXXXXXUU的格式,而下行DCI信令可以将这14个符号再指示为DDXXUUUDDXXUUU的格式。这里D为下行符号,U为上行时域符号,X为灵活时域符号。
取决于灵活符号的配置方式以及用户设备的上下行传输的类型和调度方式,当上下行传输和灵活符号发送时域上的重合时,用户设备有不同的处理方式。例如,对于高层半静态配置的上下行传输,用户设备会放弃传输;而对于 DCI调度的上行或者下行传输,用户会将进行相应的发送或者接收操作。对于物理下行控制信道(Physical Downlink Control Channel,PDCCH)的盲检操作,如果灵活符号是通过半静态下行信令配置的,用户需要执行盲检操作;而如果灵活符号是通过DCI配置的,用户不执行盲检操作。
然而,相关技术缺乏对直连通信如何使用灵活时域符号上的时频资源的方案。
而本公开涉及的各个实施例,示出了当直连通信的sidelink资源的时域符号中包含灵活时域符号时,如何对直连通信进行处理的方案,实现了直连通信与灵活时域符号的兼容。

综上所述,在本公开实施例所示的方案中,当sidelink资源对应的时域符号中存在灵活时域符号时,用户设备可以结合sidelink操作以及灵活时域符号中的上下行操作对该sidelink操作进行处理,从而提供了一种基于灵活时域符号对sidelink操作进行协调处理的方案,实现了直连通信与灵活时域符号的兼容。
图4是根据一示例性实施例示出的一种直连通信操作处理方法的流程图,该直连通信操作处理方法可以由用户设备执行,比如,该用户设备可以是图2所示的实施环境中的用户设备210。如图4所示,该方法可以包括以下步骤。
在步骤401中,对于待执行的直连通信sidelink操作,获取目标符号的符号类型。
其中,该目标符号是该sidelink操作所使用的sidelink资源所在的各个时域符号。
在本公开实施例中,当用户设备被调度了sidelink传输时,在执行对应的sidelink操作之前,用户设备首先获取对应的sidelink资源对应的各个时域符号,并根据被配置的各个灵活时域符号,确定上述sidelink资源对应的各个时域符号中是否存在灵活时域符号。
在获取到目标符号的符号类型之后,当该目标符号的符号类型指示该目标符号中存在灵活时域符号时,用户设备即可以根据该sidelink操作以及该灵活时域符号中的上下行操作,对该sidelink操作进行处理。上述对sidelink操作的过程可以请参考后续步骤。
在步骤402中,当该上下行操作为需要在灵活时域符号中执行的下行操作时,放弃该sidelink操作;
其中,该下行操作包括下行接收操作,或者,下行测量操作。
其中,当上下行操作对应的时域符号中包含上述灵活时域符号时,用户设备可以按照规则确定是需要在该灵活时域符号上执行该上下行操作,还是需要在该灵活时域符号上放弃该上下行操作。
在本公开实施例中,如果用户设备需要在上述灵活时域符号上执行的上下 行操作是下行操作,比如,下行接收基站发送的数据或者控制指令,或者,下行测量基站的信号等,则用户设备可以放弃上述sidelink操作。
在一种可能的实现方式中,上述放弃该sidelink操作,包括:
放弃该sidelink操作中的全部操作;或者,放弃该sidelink操作中,在灵活时域符号内执行的部分操作。
其中,一次调度的sidelink操作可能需要占用多个OFDM符号,该多个OFDM符号中可能有部分是灵活时域符号,其它部分是上行时域符号或者下行时域符号。用户设备在放弃上述sidelink操作时,可以放弃本次调度的所有sidelink操作,也可以只放弃本次调度的sidelink操作中,对应在上述灵活时域符号中的sidelink操作。
也就是说,当直连通信发送、接收、测量等操作发生在被配置为灵活时域符号的时域符号上时,如果用户设备在该灵活时域符号上需要执行如PDCCH监测,下行数据接收,信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)测量等下行操作时,用户设备在该灵活时域符号对应的时域资源上放弃进行直连通信发送、接收、测量等操作。其中,这里可能丢弃整个直连操作,也可能只丢弃包含重合部分的部分时隙符号上的直连操作。
在步骤403中,当该sidelink操作为sidelink发送操作,且该上下行操作为需要在灵活时域符号中执行的上行操作时,执行该sidelink发送操作;
其中,该上行操作包括上行发送操作。
在一种可选的实现方案中,该sidelink发送操作的发送功率与该上行操作的发送功率之和不超过该用户设备的发送总功率。
在一种可选的实现方案中,该当该sidelink操作为sidelink发送操作,且该上下行操作为需要在灵活时域符号中执行的上行操作时,执行该sidelink发送操作,包括:
获取该sidelink发送操作发送的信息的第一优先级,以及该上行操作发送的信息的第二优先级;当该第一优先级不低于该第二优先级时,执行该sidelink发送操作。
也就是说,当直连通信发送和灵活符号发生时域重合时,如果用户设备在上述灵活时域符号上需要执行如上行数据信道发送,上行控制信道发送,上行SRS发送等上行操作时,用户设备在该灵活时域符号对应的时域资源上可以进行直连通信发送操作。
其中,当用户设备的上行传输和直连通信发送操作发生在同一个时域符号上时,用户设备可以同时执行上行传输和直连通信发送操作,并且,两者需要按照特定规则共享上行发送功率(比如,两者的上行发送功率之和不超过用户设备的总发送功率);或者,用户设备也可以按照特定规则丢弃上行传输,或者,丢弃直连通信发送操作。
其中,用户设备按照特定规则丢弃上行传输,或者,丢弃直连通信发送操作时,可以根据两者的发送内容的类型确定优先级,比如,发送内容是控制信令的优先级高于发送内容是数据的优先级,而发送内容是数据的优先级高于发送内容是参考信号的优先级;如果发送内容的类型相同,则用户设备还可以进一步根据发送内容进一步确定两者的优先级,比如,根据发送内容的QoS需求确定优先级,例如,当上行传输和直连通信的发送内容的类型相同时,用户设备可以执行QoS需求高的发送操作,并丢弃QoS需求低的发送操作。
在步骤404中,当该sidelink操作为sidelink发送操作,且不存在该上下行操作时,获取该sidelink发送操作的调度方式,以及该灵活时域符号的配置方式。
也就是说,当直连通信发送和灵活符号发生时域重合时,且没有上行或下行操作与上述灵活时域符号发生时域重合,用户设备可以根据时隙符号的配置方式,以及直连通信发送的调度方法决定是否进行直连通信发送。
在步骤405中,根据该sidelink发送操作的调度方式,以及该灵活时域符号的配置方式,对该sidelink发送操作进行处理。
在一种可选的实现方案中,该根据该sidelink发送操作的调度方式,以及该灵活时域符号的配置方式,对该sidelink发送操作进行处理,包括:
当该sidelink发送操作的调度方式是第一调度方式,且该灵活时域符号的配置方式是第一配置方式时,放弃该sidelink发送操作;
当该sidelink发送操作的调度方式是该第一调度方式,且该灵活时域符号的配置方式是第二配置方式时,执行该sidelink发送操作;
其中,该第一调度方式指示该sidelink发送操作是由下行控制信息DCI信令动态调度的sidelink发送操作;
该第一配置方式指示该灵活时域符号由基站通过半静态信令配置,并且由该基站通过DCI信令动态指示;
该第二配置方式指示该灵活时域符号由基站通过半静态信令配置,且该基站未通过DCI信令动态对该灵活时域符号进行指示;或者,该第二配置方式指 示该灵活时域符号由基站通过针对特定用户的半静态信令配置,且该基站未通过DCI信令动态对该灵活时域符号进行指示;或者,该第二配置方式指示该灵活时域符号由该用户设备在未收到该基站的配置时,按照预配置的时隙格式配置;或者,该第二配置方式指示该灵活时域符号由该用户设备在未收到该基站的配置时,按照预配置的时隙格式配置,且由其它用户设备通过sidelink控制信息或者sidelink广播信息指示;或者,该第二配置方式指示该灵活时域符号由该用户设备在未收到该基站的配置且没有预配置时默认配置。
在一种可选的实现方案中,该根据该sidelink发送操作的调度方式,以及该灵活时域符号的配置方式,对该sidelink发送操作进行处理,包括:
当该sidelink发送操作的调度方式是第二调度方式,且该灵活时域符号的配置方式是第三配置方式时,执行该sidelink发送操作;
当该sidelink发送操作的调度方式是该第二调度方式,且该灵活时域符号的配置方式是第四配置方式时,放弃该sidelink发送操作;
其中,该第二调度方式指示该sidelink发送操作是由基站通过半静态信令配置的sidelink传输操作;或者,该第二调度方式指示该sidelink发送操作是由该用户设备自主选择sidelink资源的sidelink传输操作;或者,该第二调度方式指示该sidelink发送操作是sidelink同步信号和/或sidelink广播信道的发送操作;
该第三配置方式指示该灵活时域符号由该用户设备在未收到该基站的配置且没有预配置时默认配置;

在一种可选的实现方案中,该根据该sidelink发送操作的调度方式,以及该灵活时域符号的配置方式,对该sidelink发送操作进行处理,包括:
当该sidelink发送操作的调度方式是第三调度方式,且该灵活时域符号的配 置方式是第五配置方式时,执行该sidelink发送操作;
当该sidelink发送操作的调度方式是该第三调度方式,且该灵活时域符号的配置方式是第六配置方式时,放弃该sidelink发送操作;
其中,该第三调度方式指示该sidelink发送操作是由该用户设备之外的其它用户设备发送的sidelink控制信息调度的sidelink传输操作;
该第五配置方式指示该灵活时域符号由该用户设备在未收到该基站的配置时,按照预配置的时隙格式配置;或者,该第三配置方式指示该灵活时域符号由该用户设备在未收到该基站的配置且没有预配置时默认配置;

II)用户设备不可以使用灵活符号上的时间频率资源进行直连信号或者信道的发送,用户设备丢弃或者放弃与灵活符号发生冲突的直连发送。
这里可能丢弃整个直连发送,也可能只丢弃包含重合部分的直连发送。
用户设备在决定是否丢弃直连通信发送时,可以采用以下三种策略:
a)对于DCI调度的直连传输(A),即对应第一调度方式,当灵活符号是通过方法3指示,即对应第一配置方式时,选择处理方式II;对于DCI调度的直连传输(A),当灵活符号是通过其他方法(比如上述方法1、2、3、5或6)指示时选择处理方式I。
b)对于半静态配置的直连传输(B),或用户自主选择的直连传输(C),或者直连同步信号和直连广播信道传输(E),即对应第二调度方式,当灵活符号配置方法为6,即对应第二配置方式时,选择处理方式I;对于半静态配置的直连传输(B),或用户自主选择的直连传输(C),或者直连同步信号和直连广播信道传输(E),当灵活符号配置方法为其他方法(比如上述方法1、2、3、4或5)指示时选择处理方式II。
c)对于被其他用户设备调度的直连传输(D),即对应第三调度方式,当灵 活符号配置方法为4或者6,即对应第三配置方式时,选择处理方式I;对于被其他用户设备调度的直连传输(D),当灵活符号配置方法为其他方法(比如上述方法1、2、3或5)配置时选择处理方式II。
在步骤406中,当该sidelink操作为sidelink接收操作,且不存在该上下行操作时,执行该sidelink接收操作。
在本公开实施例中,当直连通信接收或测量和灵活符号发生时域重合时,且没有上行或下行操作与所述灵活符号发生时域重合,用户设备在灵活符号上进行接收和测量。
在一种可选的实现方案中,该sidelink接收操作包括以下操作中的至少一种:

在正确接收的sidelink控制信息和/或该sidelink控制信息关联的sidelink数据传输所使用的时频资源上进行测量。
综上所述,本公开实施例所示的方案,当sidelink资源对应的时域符号中存在灵活时域符号时,用户设备可以结合sidelink操作以及灵活时域符号中的上下行操作对该sidelink操作进行处理,从而提供了一种基于灵活时域符号对sidelink操作进行协调处理的方案,实现了直连通信与灵活时域符号的兼容。
