技术领域
本申请属于通信技术领域,具体涉及一种传输方法、UE及可读存储介质。
背景技术
为了增加新空口(New Radio,NR)旁链路(sidelink,SL)中,用户设备(User Equipment,UE)接入非授权频带(unlicensed band)的机会,现有技术中,在SL传输单元(如,时隙slot)中设定多个信道的开始位置。同时,相应地在该SL传输单元上设计多个自动增值控制(Automatic Gain Control,AGC)映射位置的AGC符号,从而使得传输数据可以在存在多个AGC符号的SL传输单元上进行SL传输。
然而,引入多个AGC符号虽然可以增加UE接入信道的机会,但是同样会对传输的SL信息,以及信道的传输参数造成影响,从而使得传输数据的传输效率和可靠性降低。
发明内容
本申请实施例提供一种传输方法、UE及可读存储介质,能够解决在传输单元上映射多个AGC符号,使得传输数据的传输效率和可靠性降低的问题。
第一方面,提供了一种传输方法,应用于UE,该方法包括:UE基于第一传输单元上的第一AGC符号,执行第一操作;其中,该第一操作包括以下任一项:在上述第一AGC符号处对第一信息进行第二操作;基于第一信道的参考资源计算该第一信道的传输参数,该第一信道的参考资源中排除上述第一传输单元上的第一AGC符号对应的资源;其中,第一AGC符号为上述第一传输单元中除第一个AGC符号之外的至少一个AGC符号。
第二方面,提供了一种传输装置,该装置包括:处理模块;该处理模块,用于UE基于第一传输单元上的第一AGC符号,执行第一操作;其中,该第一操作包括以下任一项:在上述第一AGC符号处对第一信息进行第二操作;基于第一信道的参考资源计算该第一信道的传输参数,该第一信道的参考资源中排除上述第一传输单元上的第一AGC符号对应的资源;其中,第一AGC符号为上述第一传输单元中除第一个AGC符号之外的至少一个AGC符号。
第三方面,提供了一种UE,该UE包括处理器和存储器,所述存储器存储可在所述处理器上运行的程序或指令,所述程序或指令被所述处理器执行时实现如第一方面所述的方法的步骤。
第四方面,提供了一种UE,包括处理器及通信接口,其中,所述处理器用于基于第一传输单元上的第一AGC符号,执行第一操作;其中,该第一操作包括以下任一项:在上述第一AGC符号处对第一信息进行第二操作;基于第一信道的参考资源计算该第一信道的传输参数,该第一信道的参考资源中排除上述第一传输单元上的第一AGC符号对应的资源;其中,第一AGC符号为上述第一传输单元中除第一个AGC符号之外的至少一个AGC符号。
在本申请实施例中,UE基于第一传输单元上的第一AGC符号,执行第一操作;其中,该第一操作包括以下任一项:在上述第一AGC符号处对第一信息进行第二操作;基于第一信道的参考资源计算该第一信道的传输参数,该第一信道的参考资源中排除上述第一传输单元上的第一AGC符号对应的资源;其中,第一AGC符号为上述第一传输单元中除第一个AGC符号之外的至少一个AGC符号。如此,可以在第一AGC符号处对第一传输单元上所要传输的信息进行处理,改变当前所要传输的信息的映射规则,从而降低第一AGC符号对所要传输的信息的解调性的影响;此外,在计算第一信道的参考资源的传输参数时,排除参考资源中第一传输单元上的第一AGC符号对应的资源,从而降低计算得到的传输参数不精准的影响,进而提高了传输信息的传输效率和可靠性。
第五方面,提供了一种传输方法,应用于UE,该方法包括:在参考时间段中存在N种传播类型的情况下,UE基于该N种传播类型对应的N个第二信道的传输状态,确定竞争窗口大小。
第六方面,提供了一种传输装置,该装置包括:处理模块;该处理模块,用于在参考时间段中存在N种传播类型的情况下,基于该N种传播类型对应的N个第二信道的传输状态,确定竞争窗口大小。

第八方面,提供了一种UE,包括处理器及通信接口,其中,所述处理器用于在参考时间段中存在N种传播类型的情况下,UE基于该N种传播类型对应的N个第二信道的传输状态,确定竞争窗口大小。
在相关技术中,目前还没有在参考时间段中存在的多种传播类型情况下,UE根据多种传播类型对应的信道的传输状态,确定竞争窗口大小的方案。因此,在本申请实施例中,在参考时间段中存在N种传播类型的情况下,UE基于该N种传播类型对应的N个第二信道的传输状态,确定竞争窗口大小。如此,可以在参考时间段中存在多种传播类型的情况下,确定竞争窗口大小。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple  Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备,其中,接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、WLAN接入点或WiFi节点等,基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例进行介绍,并不限定基站的具体类型。
新空口(New Radio,NR)物理旁链路控制信道(Physical SideLink Control Channel,PSCCH)/物理旁链路共享信道(Physical SideLink Shared Channel,PSSCH)资源映射的解释如下:
NR PSCCH/PSSCH以传输单元(slot)为单位进行映射,NR PSCCH/PSSCH在slot上的开始位置为固定的一个位置,PSCCH/PSSCH前的第一个符号(symbol)用于自动增值控制(Automatic Gain Control,AGC),AGC上的信息为PSCCH/PSSCH的第一个符号上的信息。
但是Rel-18中,为了增加NR旁链路(sidelink,SL)UE接入非授权频带(unlicensed band)的机会,正在考虑在slot上设定多个PSCCH/PSSCH的开始位置。那么,在每个PSCCH/PSSCH传输位置前应设定相应的AGC符号,即设定多个AGC符号以便提高解调性能。
然而,如图2所示,引入多个AGC符号虽然能够增加UE接入信道的机会,但是对于跨越多个AGC符号传输的PSCCH/PSSCH,引入多个AGC符号会影响现有的SL信息映射的规则,如果SL信息(例如旁链路控制信息(Sidelink Control Information,SCI),相位追踪参考信号(Phase-tracking reference signal,PT-RS),解调参考信号(Demodulation Reference Signal,DMRS)等等)映射规则保持不变,那么这些信息的解调性能会受到影响。同理,多个AGC符号也会影响到PSCCH/PSSCH传输参数(例如TBS,CSI等等)的计算,如果不改变传输参数的计算规则,传输效率和可靠性会受到影响。
在本申请实施例中,UE基于第一传输单元上的第一AGC符号,执行第一操作;其中,该第一操作包括以下任一项:在上述第一AGC符号处对第一信息进行第二操作;基于第一信道的参考资源计算该第一信道的传输参数,该第一信道的参考资源中排除上述第一传输单元上的第一AGC符号对应的资源;其中,第一AGC符号为上述第一传输单元中除第一个AGC符号之外的至少一个AGC符号。如此,可以在第一AGC符号处对第一传输单元上所要传输的信息进行处理,改变当前所要传输的信息的映射规则,从而降低第一AGC符号对所要传输的信息的解调性的影响;此外,在计算第一信道的参考资源的传输参数时,排除参考资源中第一传输单元上的第一AGC符号对应的资源,从而降低计算得到的传输参数不精准的影响,进而提高了传输信息的传输效率和可靠性。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的传输方法、UE及可读存储介质进行详细地说明。
图3示出了本申请实施例提供的一种传输方法的流程示意图,如图3所示,该传输方法可以包括如下步骤201:

一种示例中,结合上述步骤201,在上述第一信息包括DMRS的情况下,在上述第一AGC符号处对该第一信息进行第二操作,包括步骤201b:
步骤201b、在上述DMRS在第一传输单元上的映射位置与第一AGC符号的位置重叠的情况下,UE按照第一规则调整上述DMRS在第一传输单元上的映射位置。

示例性地,在上述DMRS的映射过程中排除上述第一AGC符号,换句话说,在映射过程中忽略第一AGC符号的位置后,在按照DMRS的映射规则将DMRS映射至第二符号。
如此,可以降低第一AGC符号对信道上携带的信息和在同一传输单元上传输的传输信息映射的影响。

例如,如果PSCCH或者PSSCH传输所占用的频域资源中子信道的数量大于或等于预设子信道数量,或者,PSCCH或者PSSCH传输所占用的频域资源占用目标资源中的占比值大于预设频域资源占比值,或者,PSCCH或者PSSCH传输所占用的频域资源为目标资源,则UE不需要在上述第一传输单元的符号中映射第一AGC信息;否则,映射第一AGC信息。
示例性地,针对上述条件2,上述预定设定可以是协议约定的或者网络侧设备配置的或者预配置的。
示例性地,当上述资源池中的频域资源的设定满足上述预定设定时,在上述第一传输单元上的符号中不映射第一AGC信息;否则,映射第一AGC信息。
例如,如果资源池中或RB set中只有一个子信道,或者,资源池设置仅允许UE间进行时分复用(Time division multiplexing,TDM),则UE不需要在上述第一传输单元的符号中映射第一AGC信息;否则,映射第一AGC信息。
示例性地,针对上述条件3,在PSCCH或者PSSCH传输的n个传输单元前,UE检测到其他UE预留的资源也在该PSCCH或者PSSCH所使用的时域资源上,和/或,另一个UE的PSCCH或者PSSCH的传输开始位置和该UE不一致。例如,该UE的PSCCH或者PSSCH从symbol#0开始传输,另一个UE的PSCCH或者PSSCH从symbol#7开始传输。此时,UE需要在上述第一传输单元的符号中映射第一AGC信息;否则,不映射第一AGC信息。
示例性地,针对上述条件4,上述第三条件包括以下至少之一:
使用的调制编码方案(Modulation and coding scheme,MCS)大于或等于预设值;
UE用预设的MCS表。
示例性地,当UE使用的上述第一信道的传输参数满足上述第三条件时,在上述第一传输单元上的符号中映射第一AGC信息;否则,不映射第一AGC信息。
例如,由于低MCS传输对AGC准确性的要求相对较低。因此,如果PSCCH或者PSSCH传输使用的大于或等于预设值,或者UE用某个预设的MCS表时,UE需要在上述第一传输单元的符号中映射第一AGC信息;否则,不映射第一AGC信息。
一种示例中,UE可以根据协议约定的或者网络侧设备配置的或者预配置的指示总是在上述第一传输单元映射第一AGC信息。
另一种示例中,UE可以自主决定是否在上述第一传输单元上的符号中映射第一AGC信息。
如此,可以通过预定条件决定是在第一传输单元的符号中映射AGC信息,从而使得第一传输单元上存在多个AGC符号。

除第一个AGC符号的额外AGC符号个数;
第一AGC符号能否与物理旁链路反馈信道(Physical SideLink Feedback Channel,PSFCH)在相同传输单元发送;
是否配置了PSFCH;
PSFCH的周期。
需要说明的是,C的值可以是1,0.75,0.5。例如,如果资源池中允许1个额外的AGC符号,该额外的AGC符号不能出现在PSFCH时机中,当没有配置PSFCH,C的值为1,当PSFCH周期为2,C的值为0.5,当PSFCH周期为4,C的值为0.75。
可选地,在本申请实施例中,结合上述步骤201,在计算上述第一信道的传输参数包括:计算上述第一信道的信道状态信息(Channel State Information,CSI)资源的情况下,本申请实施例提供的传输方法包括以下步骤601:
步骤601、按照以下任一项方式,排除上述第一传输单元上的第一AGC符号对 应的资源:
协议约定的,
网络侧设备指示是否排除第一AGC符号对应的资源;
UE自主确定是否排除第一AGC符号对应的资源。
示例性地,上述CSI资源用于反馈CSI。
示例性地,UE可以根据CSI参考信号(CSI Reference Signal,CSI-RS)传输资源上是否映射第一AGC信息自主确定是否排除第一AGC符号。
可选地,在本申请实施例中,计算上述第一信道的第二级SCI(2nd stage SCI)可用参考资源。
示例性地,上述SCI可用参考资源计算过程中排除第一AGC符号对应的C个符号的资源。
示例性地,上述第一AGC符号对应的资源可以等同于第一AGC符号占用的资源,或者基于第一AGC符号占用的资源推导出的资源。
如此,可以减小多个AGC符号在UE计算信道传输参数时产生的影响,从而提高传输数据的传输效率。
可选地,在本申请实施例中,在上述步骤401、步骤501和步骤601“排除上述第一传输单元上的第一AGC符号对应的资源”之后,本申请实施例提供的传输方法包括以下步骤701:
步骤701、在UE使用上述第一传输单元传输数据的情况下,传输第三信息。
示例性地,上述第三信息用于指示UE是否排除上述第一传输单元上的第一AGC符号对应的资源。
如此,通过指示信息告知网络侧设备UE是否排除第一传输单元上的第一AGC符号,从而使得网络侧设备可以根据该指示信息,将排除的AGC符号还原。
在相关技术中,目前还没有在参考时间段中存在的多种传播类型情况下,UE根据多种传播类型对应的信道的传输状态,确定竞争窗口大小的方案。。本申请实施例提供的传输方法,可以解决在参考时间段中存在多种传播类型的情况下,UE根据多种传播类型对应的信道的传输状态确定竞争窗口大小的问题。
图4示出了本申请实施例提供的一种传输方法的流程示意图,如图4所示,该传输方法可以包括如下步骤A:
步骤A、在参考时间段中存在N种传播类型的情况下,UE基于该N种传播类型对应的N个第二信道的传输状态,确定竞争窗口大小。其中,N为大于1的正整数。

示例性地,上述N种传播类型的优先级可以根据混合自动重传请求确认(Hybrid Automatic Repeat request-ACKnowledgement,HARQ-ACK)反馈的精准程度确定。
示例性地,上述N种传播类型的优先级排序如下:Unicast SL-HARQ enabled>groupcast option 2>groupcast option 1>SL-HARQ disabled。
示例性地,UE选择上述N种传播类型中优先级最高的传播类型(例如,Unicast SL-HARQ enabled),并根据该传播类型对应的第三信道的传输状态确定竞争窗口大小。
步骤A2、根据上述N个第二信道的传输顺序中的第四信道的传输状态,确定竞争窗口大小。
示例性地,上述第四信道为上述N个第二信道中的其中一个。
示例性地,根据上述N个第二信道的传输的先后顺序中的第四信道,或者根据N个第二信道对应的PSFCH的先后顺序中的第四信道的传输状态确定竞争窗口大小。
