Description

基于物理直连通信数据信道的通信方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种基于物理直连通信数据信道的通信方法、装置及存储介质。
背景技术
多种新业务新应用的需求持续产生，终端直连通信(sidelink)对传输带宽、通信速率、通信时延、可靠性、可扩展性等性能要求也越来越高。其中，有限的授权频谱已无法满足未来潜在的多样化应用场景和需求，所以需要研究并设计能应用在非授权频段上的终端直连通信(sidelink-unlicensed)技术。
在非授权频段，基于先听后发(listen before talk，LBT)机制进行信道监测。在监测到信道空闲时，才能发送数据。LBT机制的引入，使得sidelink信号的发送必须在监测到信道空闲的时候才能发送，即使存在sidelink信号发送时机，但是若未监测到信道空闲，也不能进行sidelink信号的发送，即sidelink信号的发送存在不确定性。为了解决LBT机制带来的不确定性，使得控制信息和数据的发送时间更加灵活，sidelink-unlicensed的物理信道和物理信号的设计需要一定的增强。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的基于物理直连通信数据信道的通信方法可应用于图1所示的直连通信***。参阅图1所示，直连通信设备之间进行直连通信的场景中，网络设备为直连通信设备1配置各种用于数据传输的传输参数。直连通信设备1，直连通信设备2和直连通信设备3进行直连通信。直连通信设备2和直连通信设备3之间可以存在障碍物。网络设备与直连通信设备之间进行通信的链路为上下行链路，直连通信设备与直连通信设备之间的链路是直连链路(Sidelink)。
本公开中，直连通信设备之间直接通信的通信场景可以是车用无线通信技术(Vehicle to Everything，V2X)业务场景。其中，V代表车载设备，X代表任何与车载设备交互的对象。当前X主要包含车载设备、手持设备、交通路侧基础设施和网络。V2X交互的信息模式包括：车载设备与车载设备之间(Vehicle to Vehicle，V2V)、车载设备与路边设备之间(Vehicle to Infrastructure，V2I)、车载设备与手持设备之间(Vehicle to Pedestrian，V2P)、车载设备与网络之间(Vehicle to Network，V2N)的交互。
随着新一代5G移动通信技术的发展，在3GPP Rel-16中利用5G NR技术实现了对新 的V2x通信服务和场景的支持，如车队管理(Vehicles Platooning)，感知扩展(Extended Sensors)，先进驾驶(Advanced Driving)，和远程驾驶(Remote Driving)等。总体来说，5G V2x Sidelink能够提供更高的通信速率，更短的通信延时，更可靠的通信质量。
直连通信设备之间直接通信的通信场景也可以是终端到终端(Device to Device，D2D)的通信场景。本公开实施例中进行直接通信的直连通信设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile station，MS)，终端(terminal)，终端设备(Terminal Equipment)等等。为方便描述，本公开实施例以下以直连通信设备为终端为例进行说明，其中，终端和UE有时会交替使用，但本领域技术人员应理解其含义的一致性。
相关技术中，sidelink中进行基于物理直连通信数据信道(Physical Sidelink Shared Channel，PSSCH)/物理直连通信控制信道(Physical Sidelink Control Channel，PSCCH)的通信传输。图2和图3示出了相关技术中NR sidelink的PSSCH传输结构。参阅图2和图3所示，传统技术中基于PSSCH通信时，分配用于sidelink的资源(即传输直连通信信号的sidelink资源)。通常传输直连通信信号的sidelink资源的首个符号为自动增益控制(automatic gain control，AGC)符号，最后一个符号为保护间隔(gap protect，GP)符号在进行直连通信信号传输时，通常是在检测到AGC符号后，复制该AGC符号后开始PSSCH传输。
相关技术中，研究并设计能应用在非授权频段上的终端直连通信(sidelink-unlicensed)技术。sidelink-unlicensed中，同样采用LBT机制进行信道监测。在监测到信道空闲时，才能发送数据。LBT机制的引入，使得sidelink-unlicensed中直连通信信号的发送必须在监测到时隙中配置的AGC符号和信道空闲的时候才能发送，即使监测到信道空闲，但是并没有监测到时隙中配置的AGC符号，则也不能发送直连通信信号，即sidelink信号的发送存在不确定性。例如参阅图2和图3所示，在第三个符号处监测到AGC符号，但是LBT失败，未监测到信道空闲，则将不能进行PSSCH传输，AGC符号的位置可以理解为是为sideink传输的开始发送位置。
有鉴于此，本公开实施例提供一种基于PSSCH的通信方法，在该通信方法中，提供一种PSSCH结构，在该PSSCH中包括多个开始发送位置，即，在传输直连通信信号的sidelink资源中包括直连通信信号的多个开始发送位置，基于该多个开始发送位置，在非授权频段上发送直连通信信号。
图4是根据一示例性实施例示出的一种基于PSSCH的通信方法的流程图，如图4所 示，基于PSSCH的通信方法用于终端中，包括以下步骤。
在步骤S11中，确定PSSCH，PSSCH中包括直连通信信号的多个开始发送位置。
在步骤S12中，基于多个开始发送位置，在非授权频段上发送直连通信信号。
本公开实施例中，PSSCH中包括直连通信信号的多个开始发送位置可以理解为是在sidelink时隙中引入多个(大于1个)PSSCH的开始发送位置。在非授权频段中基于多个开始发送位置发送直连通信信号，能够增大LBT成功后可以进行PSSCH传输的可能性，进而提高非授权频段上PSSCH传输直连通信信号成功的概率。
目前，3GPP R16已完成的终端直通链路通信(NR sidelink)和蜂窝免许可频段通信(NR-U)的技术方案和工作机制，故，本公开实施例中针对sidelink-unlicensed，可以参考和复用部分3GPP R16NR sidelink和NR-U的技术方案和工作机制。
一种实施方式中，本公开实施例中可以在sidelink-unlicensed中引入微小时隙(mini slot)，在PSSCH中包括多个mini slot，即一个时隙中含有多个mini slot。在一个时隙内，物理直连通信数据信道中微小时隙的数量与直连通信信号开始发送位置的数量相等。且多个微小时隙中的每一微小时隙中首个符号为AGC符号，最后一个符号为GP符号，AGC符号GP符号之间的符号用于传输直连通信信号。
一示例中，将mini slot的结构引入到非授权频段中，每1个mini slot中含有1个PSSCH的开始发送位置，即AGC符号开始的位置，每个mini slot中，第一个符号为AGC，第二个符号到最后一个符号之间为PSSCH/PSCCH传输符号，最后一个符号为GP。
本公开实施例PSSCH中包括的mini slot的数量可以基于用于传输直连通信信号的符号数量，以及mini slot支持的符号长度来确定。
本公开实施例中用于传输直连通信信号的符号数量可以基于直连通信起始符号(sl-StartSymbol)和直连通信符号长度(sl-LengthSymbols)确定。其中，sl-StartSymbol信息字段由无线资源控制(Radio Resource Control，RRC)配置，重用R16中已有的参数，表示可以在一个时隙中可以用于sidelink的symbol的起始symbol，取值{0,1,2,3,4,5,6,7}。sl-LengthSymbols信息字段由RRC配置，重用R16中已有的参数，表示可以在一个时隙中可以用于sidelink的symbol长度，取值：{7,8,9,10,11,12,13,14}。
本公开实施例中mini slot支持的符号长度可以复用NR-U中的mini slot的长度。
更进一步的，本公开实施例中分配给直连通信信号传输的资源中还可能存在物理直连反馈信道(Physical Sidelink feedback Channel，PSFCH)资源。PSFCH通常占用一个符号，位于一个时隙的倒数第二个符号，并且需要为PSFCH资源的配置AGC符号，在一个时隙中位于倒数第三个符号，并且在倒数第四个符号上配置GP符号。故，在进行PSSCH中包 括的mini slot的数量确定时，还需要考虑PSFCH资源。即，PSSCH中包括的mini slot的数量可以基于用于传输直连通信信号的符号数量，mini slot支持的符号长度来确定，以及PSFCH资源确定。
换言之，本公开实施例中在没有配置PSFCH资源的情况下，可以基于用于传输直连通信信号的符号数量，以及mini slot支持的符号长度来确定mini slot数量。
一示例中，sl-PSFCH-Period＝0，表示没有配置PSFCH资源。在sl-PSFCH-Period＝0，没有配置PSFCH资源的情况下，可以基于用于传输直连通信信号的符号数量，以及mini slot支持的符号长度来确定mini slot数量。
图5是本公开一示例性实施例示出的一种PSSCH结构。参阅图5所示，在进行PSSCH配置时，考虑传输直连通信信号的符号数量，以及mini slot支持的符号长度。其中，直连通信信号的符号数量可以由sl-LengthSymbols确定。其中，本公开实施例中设sl-LengthSymbols＝8，可支持的mini slot长度为4个symbol，所以PSSCH配置时可以引入2个mini slot，即包括两个PSSCH开始传输的位置。本公开实施例中，在资源映射时，复用传统的NR sidelink资源映射方式，先频域映射后时域映射，直到映射完所有的符号，在图5所示的PSSCH结构中，由于两个PSSCH的发送位置之间，间隔了用于GP的符号，这个符号上没有控制和数据信息的传输，所以，资源映射时，有如下两种方式：
方式1：该GP的符号在资源映射，进行速率匹配。
方式2：将该GP的符号进行打孔(puncture)。
本公开另一实施例中，在配置PSSCH资源的情况下，可以基于用于传输直连通信信号的符号数量，mini slot支持的符号长度来确定，以及PSFCH资源确定mini slot数量。
一示例中，sl-PSFCH-Period≠0，表示配置有PSFCH资源。在sl-PSFCH-Period≠0，配置PSFCH资源的情况下，可以基于用于传输直连通信信号的符号数量，mini slot支持的符号长度，以及PSFCH资源确定mini slot数量。换言之，sl-PSFCH-Period≠0的情况下，在配置PSFCH时，需要考虑3个符号被额外占用，即：PSFCH占用的1个符号，另外因PSFCH而引入的1个符号用作GP和1个符号用作AGC。
图6是本公开一示例性实施例示出的一种PSSCH结构。参阅图6所示，在进行PSSCH配置时，考虑用于传输直连通信信号的符号数量，mini slot支持的符号长度，以及PSFCH资源。直连通信信号的符号数量可以由sl-LengthSymbols确定。其中，本公开实施例中设sl-LengthSymbols＝11，可支持的mini slot长度为4个symbol，PSFCH占用一个符号。其中，所以引入2个mini slot，引入两个PSSCH开始传输的位置。两个PSSCH的发送位置之间，间隔了用于AGC和GP的符号。
本公开实施例中，在资源映射时，复用传统的NR sidelink资源映射方式，先频域映射后时域映射，直到映射完所有的符号，在图6所示的PSSCH结构中，由于两个PSSCH的发送位置之间，间隔了用于AGC和GP的符号，GP这个符号上没有控制和数据信息的传输，所以，资源映射时，有如下两种方式：
方式1：该GP的符号在资源映射，进行速率匹配。
方式2：将该GP的符号进行打孔(puncture)。
进一步的，本公开实施例中可以配置多种PSSCH，在进行直连通信信号传输时，在配置的多种PSSCH中确定每次传输时所需的单次传输中使用的PSSCH。
本公开实施例中，配置的多种PSSCH中每一种PSSCH均包括多个mini slot，每个mini slot中有一个开始发送位置，且各PSSCH中包括的mini slot的数量不同。即，每一数量的mini slot对应一种PSSCH。
在一些可能的实现方式中，多种PSSCH中每一种PSSCH中均包括多个mini slot，每个mini slot中有一个开始发送位置，且各PSSCH中包括的mini slot的数量不同。在另一些可能的实现方式中，多种PSSCH中的一部分PSSCH中包括多个mini slot，每个mini slot中有一个开始发送位置，且各PSSCH中包括的mini slot的数量不同。
可以理解的是，本公开实施例中多种PSSCH中每一种PSSCH均适用于上述实施例中涉及的PSSCH结构，具体可参阅上述实施例的相关描述。
一示例中，配置多种PSSCH的结构，每种PSSCH的结构含有不同数量的mini slot，mini slot的数量由可支持的mini slot长度、以及sl-PSFCH-Period(是否配置PSFCH资源)确定。即，mini slot的数量由可用于sidelink传输的符号数量来决定。

一种实施方式中，本公开实施例中可以由网络设备配置多种PSSCH，并将配置的多种PSSCH指示给终端。

一种实施方式中，可以基于RRC信息指示单次传输中使用的PSSCH。
其中，PSSCH中包括有多个mini slot，mini slot数量与开始发送位置数量相等，每一种PSSCH对应一种mini slot数量。故，本公开实施例中可以通过指示mini slot数量指示PSSCH。

在步骤S21中，基于RRC信息指示的mini slot的数量，确定单次传输中使用的PSSCH，每一种mini slot的数量对应一种PSSCH。

一种实施方式中，mini slot的数量基于用于传输直连通信信号的符号数量，以及mini slot支持的符号长度来确定。另一种实施方式中，mini slot的数量基于用于传输直连通信信号的符号数量，mini slot支持的符号长度，以及物理直连反馈信道资源确定。

本公开实施例中，配置多种PSSCH的情况下，网络设备可以通过指示信息指示单次传输中使用的PSSCH。
一种实施方式中，发送指示信息，包括：
发送RRC信息，RRC信息用于指示mini slot的数量，每一种mini slot的数量对应一种PSSCH。
