Description

用于无线制式切换的通信方法、装置和电子设备 技术领域
本申请涉及无线通信技术领域，尤其涉及一种用于无线制式切换的通信方法、装置和电子设备。
背景技术
近年来，车用无线通信技术(Vehicle to Everything，简称V2X)得到了蓬勃的发展。V2X可提供两种通信接口，分别称为Uu接口(蜂窝通信接口)和PC5接口(侧行链路通信接口)。V2X在PC5接口上可以提供两种不同的无线制式，并分别用于不同的业务场景，以提供丰富的功能。然而V2X终端需要在两种无线制式之间的切换，此种情况下，势必需要有相应的切换时间(Switching Period)。
现有技术中，通常采用固定放置无线制式切换时间的方式。然而，由于在切换时间内，终端无法传输信号，这段时间属于额外的网络开销。这样一来，势必会造成包含切换时间的载波的传输质量降低。此外，针对承载的信息优先级不一致的无线制式之间切换，现有用于无线制式切换的通信方法无法反应动态的优先级引起的差异。

下面参考附图对本申请提供的用于无线制式切换的通信方法、装置和电子设备进行详细描述。
图1是根据本申请提出的一种用于无线制式切换的通信方法的示意图。其中，需要说明的是，本申请的用于无线制式切换的通信方法，可以在无线制式信息包的发送端执行。
如图1所示，本申请提出的用于无线制式切换的通信方法，包括如下步骤：
S101、确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级。
需要说明的是，V2X在PC5接口上提供了基于长期演进(Long Term Evolution，简称 LTE)技术的第四代通信侧行链路(Long Time Evolution Sidelink，简称LTE Sidelink)，以及基于第五代移动通信(5th Generation，简称5G)技术的新空口侧行链路(New Radio Sidelink，简称NR Sidelink)，共两种无线制式。其中，LTE sidelink主要提供基本业务功能，而NR sidelink主要用于更先进的业务场景。
本申请中，终端在进行NR Sidelink与LTE Sidelink的切换时，终端内部可以通过接收、解调等方式确定与两个载波相关联的优先级信息，即与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级。
其中，前述第一无线制式可以为NR Sidelink，也可以为LTE Sidelink，且第一无线制式与第二无线制式不相同。例如，第一无线制式可以为NR Sidelink，第二无线制式可以为LTE Sidelink；又例如，第一无线制式可以为LTE Sidelink，第二无线制式可以为NR Sidelink。
S102、根据第一优先级和第二优先级，确定目标无线制式。
可选地，在确定了到第一优先级和第二优先级后，根据第一优先级和第二优先级，将两者进行比较，并在识别两个载波存在不同的优先等级时，可以将优先级低的无线制式确定为目标无线制式。
举例而言，在获取到第一优先级和第二优先级后，可以将第一优先级和第二优先级进行比较，若第一优先级低于第二优先级，则可以将第一优先级的无线制式确定为目标无线制式。
可选地，在确定了到第一优先级和第二优先级后，可以是综合第一和第二优先级，来确定目标无线制式。
举例而言，在获取到第一优先级和第二优先级后，可以基于涉及第一优先级和第二优先级的特定计算公式，得到最终的优先级计算结果，进而根据优先级计算结果确定目标制式。
S103、将切换时间的时域位置配置在目标无线制式的传输时段内。
其中，传输时段，可以为帧、时隙(Slot)和子时隙(Mini Slot)等。
本申请中，在确定目标无线制式后，可以将切换时间的时域位置配置在目标无线制式的传输时段内。
举例而言，在将第一优先级的无线制式确定为目标无线制式后，可以切换时间的时域位置配置在第一优先级的无线制式的传输时隙中。
根据本申请实施例的用于无线制式切换的通信方法，可以通过确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级，并根据第一优先级和第二优先级，确定目标无线制式，进而将切换时间的时域位置配置在目标无线制式的传输时段内。由此，本申请能够将切换时间的时域位置配置在优先级低的无线制式的传输 时段内，不再依赖使用固定的切换时间的方式确定无线制式切换时间时域位置，能够反应动态的优先级引起的差异，避免了承载了重要信息的侧行链路产生额外信令开销导致传输质量下降的技术问题。
需要说明的是，在实际应用中，获取到的第一优先级和第二优先级可能是不同的，也可能是相同的，即两个载波可能存在相关联的不同的优先级，也可能存在相同的优先级。由此，本申请中，在第一优先级和第二优先级相同时，可以由终端自行决定无线制式切换时间的时域位置。
作为一种可能的实现方式，如图2所示，本申请提出的用于无线制式切换的通信方法，包括如下步骤：
S301、确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级。
该步骤S301与步骤S101相同，此处不再赘述。
S302、根据第一优先级和第二优先级，将第一无线制式和第二无线制式中的一个确定为目标无线制式。
本申请中，在获取到第一优先级和第二优先级后，可以将第一优先级和第二优先级进行比较。
若识别第一优先级高于第二优先级，说明两个载波存在相关联的不同的优先等级，则可以响应于第一优先级高于第二优先级，将第二无线制式确定为目标无线制式。
若识别第一优先级和第二优先级相同，说明两个载波不存在相关联的不同的优先等级，则可以响应于第一优先级和第二优先级相同，将第一无线制式和第二无线制式中的一个确定为目标无线制式。此种情况下，第一优先级可以为与LTE Sidelink相关联的优先级，也可以为与NR Sidelink相关联的优先级，第一优先级与第二优先级不一致。
S303、将切换时间的时域位置配置在目标无线制式的传输时段内。
该步骤S303与步骤S103相同，此处不再赘述。
根据本申请实施例的用于无线制式切换的通信方法，可以通过获取与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级，并在识别第一优先级和第二优先级相同时，可以将第一无线制式和第二无线制式中的一个确定为目标无线制式，进而将切换时间的时域位置配置在目标无线制式的传输时段内。由此，本申请能够在第一优先级和第二优先级相同时，由终端自行决定将切换时间放置在第一无线制式和第一无线制式中任一无线制式的传输时段内，提高了用于无线制式切换的通信过程中的有效性和可靠性。
需要说明的是，在实际应用中，存在第一优先级或者第二优先级获取失败的情况，即 存在终端在切换之前没有获得完整的与两个载波相关联的优先级的情况。由此，本申请中，在第一优先级和第二优先级中的任意一个获取失败时，可以由终端自行决定无线制式切换时间的时域位置。
作为一种可能的实现方式，如图3所示，本申请提出的用于无线制式切换的通信方法，包括如下步骤：

其中，获取失败，指的是没有获取到优先级信息，或者没有获取到完整的优先级信息的情况。
本申请中，在获取到第一优先级和第二优先级后，可以判断第一优先级和第二优先级中的任意一个优先级是否获取失败，并在识别第一优先级和第二优先级中的任意一个获取失败时，可以将获取成功的无线制式确定为目标无线制式，即可以将第一无线制式和第二无线制式中的一个确定为目标无线制式。
举例而言，若第一优先级获取失败，则可以将获取成功的第二无线制式确定为目标无线制式。
S503、将切换时间的时域位置配置在目标无线制式的传输时段内。
该步骤S503与步骤S103相同，此处不再赘述。
根据本申请实施例的用于无线制式切换的通信方法，可以通过确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级，并判断第一优先级和第二优先级中的任意一个优先级是否获取失败，并在识别第一优先级和第二优先级中的任意一个获取失败时，将第一无线制式和第二无线制式中的一个确定为目标无线制式，进而将切换时间的时域位置配置在目标无线制式的传输时段内。由此，本申请能够在第一优先级和第二优先级中的任意一个获取失败时，将获取成功的无线制式确定为目标无线制式，避免了在第一优先级和第二优先级中的任意一个获取失败时无法有效确定无线制式切换时间时域位置的问题，提高了用于无线制式切换的通信过程中的有效性和可靠性。
需要说明的是，本申请中，在确定目标无线制式之后，可以根据目标无线制式与当前无线制式，确定切换时间的对齐方式。其中，当前无线制式，指的是设备当前所处的无线通信制式，即进行无线制式切换前的无线制式。
作为一种可能的实现方式，如图4所示，本申请提出的用于无线制式切换的通信方法，包括如下步骤：
S701、确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级。
S702、判断第一优先级和第二优先级中的任意一个优先级是否获取失败。
可选地，若识别第一优先级和第二优先级中的任意一个优先级获取失败，则可以执行步骤S703；若识别第一优先级和第二优先级均获取成功，则可以执行步骤S704。
S703、将第一无线制式和第二无线制式中的一个确定为目标无线制式。
S704、判断第一优先级和第二优先级是否相同。
可选地，若识别第一优先级和第二优先级相同，则可以执行步骤S705；若识别第一优先级和第二优先级不相同，则可以执行步骤S706。

S706、将优先级低的无线制式确定为目标无线制式。
S707、将切换时间的时域位置配置在目标无线制式的传输时段内。
需要说明的是，在完成步骤S703、S705和S706中的任一步骤后，可以执行步骤S707。
前述步骤S701～S707的实施过程可以参考上述用于无线制式切换的通信方法描述中的相关记载，此处不再赘述。
S708、判断目标无线制式与当前无线制式是否一致。
可选地，若识别目标无线制式与当前无线制式一致，则可以执行步骤S709；若识别目标无线制式与当前无线制式不一致，则可以执行步骤S710。
举例而言，若获取到目标无线制式为NR Sidelink、当前无线制式为NR Sidelink，此种情况下，识别目标无线制式与当前无线制式一致，则可以执行步骤S709；若获取到目标无线制式为NR Sidelink、当前无线制式为LTE Sidelink，此种情况下，识别目标无线制式与当前无线制式不一致，则可以执行步骤S710。
S709、将切换时间的末端与目标无线制式的传输时段的结尾对齐。
举例而言，如图5所示，识别目标无线制式与当前无线制式均为NR Sidelink，即目标无线制式与当前无线制式一致，则可以将切换时间的末端与NR Sidelink的传输时段的结尾对齐。
S710、将切换时间的起始端与目标无线制式的传输时段的开头对齐。
举例而言，如图6所示，识别目标无线制式为LTE Sidelink、当前无线制式为NR Sidelink，即目标无线制式与当前无线制式不一致，则可以将切换时间的起始端与LTE Sidelink的传输时段的开头对齐。
需要说明的是，前述切换时间的对齐方式也适用于无线制式的多次切换过程。
例如，NR Sidelink优先级较低，此种情况下，从NR Sidelink切换至LTE Sidelink时，又从LTE Sidelink切换至NR Sidelink时，切换时间的对齐方式如图7(a)所示。
又例如，LTE Sidelink优先级较低，此种情况下，从NR Sidelink切换至LTE Sidelink时，又从LTE Sidelink切换至NR Sidelink时，切换时间的对齐方式如图7(b)所示。
根据本申请实施例的用于无线制式切换的通信方法，可以通过确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级，并判断第一优先级和第二优先级中的任意一个优先级是否获取失败，并在识别第一优先级和第二优先级中的任意一个获取失败时，将第一无线制式和第二无线制式中的一个确定为目标无线制式，进而将切换时间的时域位置配置在目标无线制式的传输时段内。由此，本申请能够在第一优先级和第二优先级中的任意一个获取失败时，将获取成功的无线制式确定为目标无线制式，避免了在第一优先级和第二优先级中的任意一个获取失败时无法有效确定无线制式切换时间时域位置的问题，提高了用于无线制式切换的通信过程中的有效性和可靠性。
需要说明的是，本申请中，在试图确定与获取第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级时，可以通过对侧行链路控制信息进行解调，得到第一优先级和第二优先级。
作为一种可能的实现方式，如图8所示，本申请提出的用于无线制式切换的通信方法，包括如下步骤：
S901、获取物理侧行链路控制信道上承载的侧行链路控制信息。
本申请中，在侧行链路通信过程中，终端可以接收车载设备等发送端发送的物理侧行链路控制信道上承载的侧行链路控制信息(Sidelink Control Information，简称SCI)及通信数据。其中，SCI可以用于解码通信数据。
S902、对侧行链路控制信息进行解调，得到第一优先级和第二优先级。
可选地，在获取到物理侧行链路控制信道上承载的SCI之后，终端内部可以通过解调物理侧行链路控制信道(Physical Sidelink Control Channel，简称PSCCH)上承载的SCI，确定获得与两个载波相关联的优先级信息，即与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级。
S903、判断第一优先级和第二优先级中的任意一个优先级是否获取失败。
可选地，若识别第一优先级和第二优先级中的任意一个优先级获取失败，则可以执行步骤S904；若识别第一优先级和第二优先级均获取成功，则可以执行步骤S905。

S906、将第一无线制式和第二无线制式中的一个确定为目标无线制式。
S907、将优先级低的无线制式确定为目标无线制式。
S908、将切换时间的时域位置配置在目标无线制式的传输时段内。
需要说明的是，在完成步骤S904、S906和S907中的任一步骤后，可以执行步骤S908。
前述步骤S903～S908的实施过程可以参考上述用于无线制式切换的通信方法描述中的相关记载，此处不再赘述。
S909、判断目标无线制式与当前无线制式是否一致。
S910、将切换时间的末端与目标无线制式的传输时段的结尾对齐。
S911、将切换时间的起始端与目标无线制式的传输时段的开头对齐。
需要说明的是，若接收端为仅支持唯一无线制式的设备，例如发送端由无线制式1切换到无线制式2，则接送端由无线制式1的设备变为无线制式2的设备，此时，接收端(无线制式1的设备、无线制式2的设备)均不需要执行本申请提出的用于无线制式切换的通信方法，并且只能接收与自身无线制式一致的无线制式信息包。
若接收端为可以支持两种无线制式的设备，即支持LTE Sidelink无线制式和NR Sidelink无线制式，则接收端可以执行本申请提出的用于无线制式切换的通信方法，以确定切换时间的时域位置，并根据确定出的切换时间时域位置进行切换；也可以根据发送端发送的预设切换时间时域位置进行切换。
根据本申请实施例的用于无线制式切换的通信方法，在试图确定与第一无线制式信息包相关联的第一优先级和与第二无线制式信息包相关联的第二优先级时，可以通过获取PSCCH上承载的SCI，并对SCI进行解调，得到第一优先级和第二优先级，并根据第一优先级和第二优先级，确定为目标无线制式，进而将切换时间的时域位置配置在目标无线制式的传输时段内，不再依赖使用固定的切换时间的方式确定无线制式切换时间时域位置，能够反应动态的优先级引起的差异，避免了承载了重要信息的侧行链路产生额外信令开销导致传输质量下降的技术问题。
与上述几种实施例提供的用于无线制式切换的通信方法相对应，本申请还提供一种用于无线制式切换的通信装置，由于本申请实施例提供的用于无线制式切换的通信装置与上述几种实施例提供的用于无线制式切换的通信方法相对应，因此在用于无线制式切换的通信方法的实施方式也适用于本实施例提供的用于无线制式切换的通信装置，在本实施例中不再详细描述。图9～图11是根据本申请提出的用于无线制式切换的通信装置的结构示意图。
