Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
在车联网(vehicle to everything，V2X)通信系统中，终端设备既可以通过上行链路(uplink，UL)与网络设备通信，又可以通过侧行链路(sidelink，SL)与另一终端设备通信。现有技术中，当上行链路上的传输与侧行链路上的传输存在冲突时，终端设备可根据优先级的比较结果，放弃进行某个传输链路上的传输，或者降低该传输链路上的发送功率。该优先级比较的原则为，若上行链路上存在与随机接入过程(random access process，RACH)或者紧急呼叫(emergency call)相关的消息，则优先进行上行链路上的传输。若上行链路不存在与RACH或emergency call相关的消息，则进一步将侧行链路上待传输业务的优先级与一预设的优先级阈值进行比较。若侧行链路上待传输业务的优先级高于预设的优先级阈值表示的优先级，则优先进行侧行链路上的传输。否则，若侧行链路上待传输业务的优先级低于或等于预设的优先级阈值表示的优先级，则优先进行上行链路上的传输。
由于在进行优先级比较时，除了RACH和emergency call之外，仅考虑了侧行链路上待传输的业务的优先级，没有考虑上行链路上待传输业务的优先级，因此，当上行链路上存在一些优先级较高的待传输业务时，例如超可靠低时延通信(ultra reliable and low latency communication，URLLC)业务，终端设备也无法优先发送侧行链路的待传输业务，从而无法保障侧行链路上高优先级业务的传输性能。
发明内容

实施例一
请参考图2，为本申请实施例提供的一种通信方法的流程示意图，该方法具体包括如下的步骤S201至步骤S202：
步骤S201、终端设备同时存在上行链路的传输和侧行链路的传输。
所述上行链路的传输可使用物理上行共享信道(physical uplink shared channel，PUSCH)和/或物理上行控制信道(physical uplink control channel，PUCCH)，所述侧行链路的传输可使用PSSCH信道。进一步地，所述上行链路的传输可以为初传或重传，所述侧行链路的传输也可以为初传或重传。
在步骤S201中，终端设备可确定同时存在上行链路的传输和侧行链路的传输，所述同时存在上行链路的传输和侧行链路的传输可以为，上行链路的传输所使用的时域资源与侧行链路的传输所使用的时域资源存在部分或全部重叠。
在一种可能的设计中，终端设备不仅同时存在上行链路的传输和侧行链路的传输，而且上行链路的传输与侧行链路的传输之间还存在冲突。本申请实施例中，上行链路的传输与侧行链路的传输可具有多种可能的冲突场景。例如，上行链路的传输与侧行链路的传输存在冲突可以为，上行链路的传输所使用的时域资源与侧行链路的传输所使用的时域资源存在部分或全部重叠，而且上行链路的传输与侧行链路的传输共享/使用相同的载波(carriers)。再例如，上行链路的传输与侧行链路的传输存在冲突也可以为，上行链路的传输所使用的时域资源与侧行链路的传输所使用的时域资源存在部分或全部重叠，上行链路的传输与侧行链路的传输使用不同的载波，但是共享/使用相同的发射链Tx chain和功率预算power budget。所述发射链Tx chain是指射频发送通道，也可以称为射频发送链路，所述功率预算也可以称为功率目标。
步骤S202、在第一条件、第二条件、第三条件、第四条件中的一项或多项条件均不满足的情况下，终端设备进行侧行链路的传输；或者，在第一条件、第二条件、第三条件、第四条件中的一项或多项条件中存在任一条件满足的情况下，终端设备进行上行链路的传输。
应理解，所述步骤S202中描述的技术方案可以应用在同时存在上行链路的传输和侧行链路的传输的场景下，也可以应用在同时存在上行链路的传输和侧行链路的传输，且上行链路的传输与侧行链路的传输存在冲突的场景下。可选地，所述步骤S202中描述的技术方案还可以应用在跨无线接入技术(cross-radio access technology，cross-RAT)的场景下，即所述上行链路和所述侧行链路可支持相同或不同的通信制式。例如，上行链路可支持第一通信制式或第二通信制式，侧行链路可支持第一通信制式或第二通信制式，所述第一通信制式可以为NR，所述第二通信制式可以为LTE；或者，所述第一通信制式可以为LTE，所述第二通信制式可以为NR。
所述步骤S202也可以理解为，若第一条件、第二条件、第三条件、第四条件中的一项或多项条件中存在任一条件满足，那么终端设备优先进行上行链路的传输。否则，若第一条件、第二条件、第三条件、第四条件中的一项或多项条件均不满足，那么终端设备优先进行侧行链路的传输。
本申请实施例中，终端设备优先进行上行链路的传输是指，终端设备只进行上行链路 的传输，放弃侧行链路的传输，或者，终端设备同时进行上行链路的传输和侧行链路的传输，但是降低侧行链路上的发送功率，或者，终端设备先进行上行链路的传输，后进行侧行链路的传输。类似的，终端设备优先进行侧行链路的传输是指，终端设备只进行侧行链路的传输，放弃上行链路的传输，或者，终端设备同时进行上行链路的传输和侧行链路的传输，但是降低上行链路上的发送功率，或者，终端设备先进行侧行链路的传输，后进行上行链路的传输。
由步骤S202可知，终端设备可根据一项或多项条件，来判断是优先进行上行链路的传输，还是优先进行侧行链路的传输。本申请实施例中，若将用来判断终端设备应优先进行上行链路的传输或侧行链路的传输的一项或多项条件看做是一条件集合，那么终端设备判断应优先进行上行链路的传输，还是优先进行侧行链路的传输的过程还可以为：终端设备判断该条件集合中的每项条件是否满足。若该条件集合中存在任一条件满足，终端设备可确定优先进行上行链路的传输，否则，若该条件集合中的各项条件均不满足，终端设备可确定优先进行侧行链路的传输。
可以理解，该条件集合中可以包括第一条件、第二条件、第三条件、第四条件中的一项或多项条件，或者包括第一条件、第二条件、第三条件、第四条件、第五条件中的一项或多项条件，或者包括第一条件、第二条件、第三条件、第四条件、第五条件、第六条件中的一项或多项条件，或者包括第一条件、第二条件、第三条件、第四条件、第六条件中的一项或多项条件。

而且，终端设备可按照一个预设的顺序逐一判断条件集合中的每项条件是否满足。例如，终端设备可按照第六条件、第五条件、第一条件、第二条件、第三条件、第四条件的顺序进行逐一判断。
下面对上述各项条件中涉及到的终端设备在上行链路和侧行链路上传输的各种信息以及对应的优先级进行详细介绍。
本申请实施例中，终端设备可通过上行链路向网络设备发送UL MAC PDU，该UL MAC PDU承载在PUSCH上。该UL MAC PDU中可包括上行链路媒介访问控制单元(uplink medium access control element，UL MAC CE)和上行链路媒介访问服务数据单元(uplink medium access service data unit，UL MAC SDU)，其中，UL MAC CE中可包括UL BSR MAC CE、SL BSR MAC CE、以及各种其他类型的MAC CE，例如，其他类型的MAC CE可包括小区无线网络临时标识MAC CE、配置授权确认MAC CE、不包括用于填充的上行链路缓存状态报告non-padding UL BSR MAC CE、不包括用于填充的侧行链路缓存状态报告non-padding SL BSR MAC CE、功率余量报告PHR MAC CE等。UL MAC SDU是指用于承载数据的逻辑信道。需要说明的是，在本申请的描述中，单独出现的逻辑信道可以理解为上行链路逻辑信道。应理解，在本申请中，UL BSR MAC CE包括non-padding UL BSR MAC CE和用于填充的上行链路缓存状态报告padding UL BSR MAC CE，SL BSR MAC CE包括non-padding SL BSR MAC CE和用于填充的上行链路缓存状态报告padding SL BSR MAC CE。
终端设备还可通过上行链路向网络设备发送调度请求(scheduling request，SR)、信道 状态信息(channel state information，CSI)、ACK/NACK等信息，这些SR、CSI、ACK/NACK等信息承载在PUCCH上。其中，SR可包括UL SR和SL SR，UL SR是指上行链路逻辑信道触发的调度请求，SL SR是指侧行链路逻辑信道触发的调度请求。
此外，终端设备还可通过侧行链路向其他终端设备发送SL MAC PDU，该SL MAC PDU中可包括SL MAC SDU，SL MAC SDU是指承载控制信息和/或数据信息的侧行链路逻辑信道。
鉴于此，上述各项条件中所涉及到的UL BSR MAC CE对应的优先级可以为触发上行链路缓存状态报告UL BSR的逻辑信道的优先级，或者上行链路中存在待传输数据的逻辑信道的优先级，或者UL BSR MAC CE包括的缓冲区大小BS所关联的逻辑信道的优先级。可选地，该UL BSR MAC CE对应的优先级还可以为触发UL BSR的逻辑信道的最高优先级，或者上行链路中存在待传输数据的逻辑信道的最高优先级，或者UL BSR MAC CE包括的缓冲区大小(buffer size，BS)所关联的逻辑信道的最高优先级。应理解，待传输数据可以理解为有效数据。可选地，UL BSR MAC CE对应的优先级为UL MAC PDU组包时所判断的优先级，或者，UL BSR MAC CE对应的优先级为UL MAC PDU传输时所判断的优先级。可选的，触发UL BSR的逻辑信道为满足这个UL BSR MAC CE关联的UL-SCH资源的LCP restriction的逻辑信道，上行链路中存在待传输数据的逻辑信道为满足这个UL BSR MAC CE关联的UL-SCH资源的LCP restriction的逻辑信道。
上述各项条件中所涉及到的UL SR对应的优先级可以为触发该UL SR的逻辑信道的优先级。可选地，该UL SR对应的优先级可以为触发该UL SR的逻辑信道的最高优先级。可选地，触发该UL SR的逻辑信道为能够关联到这个UL SR对应的PUCCH资源的逻辑信道。

上述各项条件中所涉及到的SL SR对应的优先级可以为触发该SL SR的侧行链路逻辑信道的优先级。可选地，该SL SR对应的优先级可以为触发该SL SR的侧行链路逻辑信道的最高优先级。可选地，触发该SL SR的侧行链路逻辑信道为能够关联到这个SL SR对应的PUCCH资源的侧行链路逻辑信道。
上述各项条件中所涉及到指定逻辑信道对应的non-padding UL BSR MAC CE、指定侧行链路逻辑信道对应的non-padding SL BSR MAC CE、指定业务对应的non-padding UL BSR MAC CE、指定业务对应的non-padding SL BSR MAC CE。指定逻辑信道或者指定侧 行链路逻辑信道可以通过逻辑信道优先级或者侧行链路逻辑信道优先级确定，例如，指定逻辑信道优先级0,1,2，当触发non-padding UL BSR对应的逻辑信道最高优先级属于0,1,2列表范围时，或者当前上行链路中存在的待传输数据的逻辑信道属于0,1,2列表范围时，或者UL BSR MAC CE包括的缓冲区大小BS所关联的逻辑信道的优先级属于0,1,2列表范围时，则该UL BSR MAC CE属于指定逻辑信道对应的non-padding UL MAC CE。
上述各项条件中所涉及到的UL ACK/NACK反馈对应的优先级可以为UL ACK/NACK反馈所关联的下行链路媒介访问协议数据单元(downlink medium access protocol data unit，DL MAC PDU)或传输块(transport block，TB)包括的逻辑信道的优先级。可选地，该UL ACK/NACK反馈对应的优先级可以为UL ACK/NACK反馈所关联的DL MAC PDU或TB包括的逻辑信道的最高优先级。

应理解，上述各项条件中所涉及的UL MAC PDU中包括的MAC CE和逻辑信道也可以包括UL MAC PDU还没有完成组包的情况。举例来说，UL MAC PDU中包括的MAC CE和逻辑信道也可以替换为能够满足UL-SCH资源的LCP restrictions限制的MAC CE和逻辑信道。应理解，本申请实施例中的侧行链路逻辑信道的优先级也可以为PC5口第五代通信服务质量标识(PC5 5G quality of service identifier，PQI)的优先级(priority level)。可选地，当一个侧行链路逻辑信道关联多个PQI时，侧行链路逻辑信道的优先级可以为其中优先级最高的PQI的优先级。如此，SL MAC PDU中包括的侧行链路逻辑信道的最高优先级也可以理解为SL MAC PDU中包括的PQI中的最高PQI优先级。
应理解，上述各项条件中所涉及的SL MAC PDU中包括的侧行链路逻辑信道也可以包括SL MAC PDU还没有完成组包的情况；举例来说，UL MAC PDU中包括侧行链路逻辑信道也可以替换为通过能够满足SL-SCH资源的LCP restrictions限制的侧行链路逻辑信道。
根据上述内容可知，上行链路中可能存在待发送的UL BSR MAC CE和UL SR，也有可能存在待发送的SL BSR MAC CE和SL SR，但是UL BSR MAC CE和UL SR对应的优先级与SL BSR MAC CE和SL SR对应的优先级的表示方式不同。
示例性的，UL BSR MAC CE对应的优先级和UL SR对应的优先级可以用逻辑信道的优先级表示。即，根据UL BSR MAC CE对应的优先级可以为触发UL BSR的逻辑信道的最高优先级，或者为上行链路中存在待传输数据的逻辑信道的最高优先级，或者为UL BSR MAC CE包括的缓冲区大小BS所关联的逻辑信道的优先级；UL SR对应的优先级可以为触发UL SR的逻辑信道的最高优先级。而SL BSR MAC CE对应的优先级和SL SR对应的 优先级可以用侧行链路逻辑信道的优先级表示。即，SL BSR MAC CE对应的优先级可以为触发SL BSR的侧行链路逻辑信道的最高优先级，或者为侧行链路中存在待传输数据的侧行链路逻辑信道的最高优先级，或者为UL BSR MAC CE包括的缓冲区大小BS所关联的逻辑信道的优先级。SL SR对应的优先级可以为触发该SL SR的侧行链路逻辑信道的最高优先级。
一般地，本申请实施例提供的第一条件中所涉及到的UL MAC PDU中包括的逻辑信道的最高优先级、UL BSR MAC CE对应的优先级、UL SR对应的优先级、UL MAC PDU中包括的MAC CE的优先级、以及UL ACK/NACK反馈对应的优先级均可以用逻辑信道的优先级。本申请实施例提供的第二条件和第三条件中所涉及到的SL BSR MAC CE对应的优先级、SL SR对应的优先级、以及SL ACK/NACK反馈对应的优先级均可以用侧行链路逻辑信道的优先级表示。
由于逻辑信道的优先级和侧行链路逻辑信道的优先级的表示方式不同，本申请实施例中，在判断上行链路中待传输业务的优先级高低时，可将逻辑信道的优先级与侧行链路逻辑信道的优先级分别考虑。
在一种可能的设计中，终端设备可将UL BSR MAC CE对应的优先级、UL SR对应的优先级等可以用逻辑信道优先级表示的优先级与第一阈值进行比较，将SL BSR MAC CE对应的优先级、SL SR对应的优先级等可以用侧行链路逻辑信道优先级表示的优先级与第二阈值进行比较。例如，当UL BSR MAC CE对应的优先级高于或等于第一阈值表示的优先级时，可认为该UL BSR MAC CE对应的优先级比较高，即上行链路上的待传输业务的优先级较高，需要优先进行上行链路的传输。当UL SR对应的优先级高于或等于第一阈值表示的优先级时，可认为该UL SR对应的优先级比较高，即上行链路上待传输业务的优先级较高，需要优先进行上行链路的传输。再例如，当SL BSR MAC CE对应的优先级高于或等于第二阈值表示的优先级时，可认为该SL BSR MAC CE对应的优先级比较高，即上行链路上的待传输业务的优先级较高，需要优先进行上行链路的传输。当SL SR对应的优先级高于或等于第二阈值表示的优先级时，可认为该SL SR对应的优先级比较高，即上行链路上待传输业务的优先级较高，需要优先进行上行链路的传输。
如此，通过设置两个用于优先级比较的阈值，分别应用于上行链路中传输的被上行链路逻辑信道触发的业务和被侧行链路逻辑信道触发的业务，从而能够更准确地衡量上行链路上待传输业务的优先级，有效保障上行链路上待传输业务的传输性能。
在另一种可能的设计中，终端设备可将UL BSR MAC CE对应的优先级、UL SR对应的优先级等可以用逻辑信道优先级表示的优先级与第一阈值进行比较，将SL BSR MAC CE对应的优先级、SL SR对应的优先级等可以用侧行链路逻辑信道优先级表示的优先级与SL MAC PDU中包括的侧行链路逻辑信道的最高优先级进行比较。例如，当SL BSR MAC CE对应的优先级高于或等于SL MAC PDU中包括的侧行链路逻辑信道的最高优先级时，可认为该SL BSR MAC CE对应的优先级较高，即上行链路上待传输业务的优先级较高，需要优先进行上行链路的传输。
本申请实施例中，第一阈值和第二阈值可以用数值表示。与此同时，逻辑信道的优先级也可以用数值表示，而且数值越小时，可表示对应的优先级越高。如此，结合上文中所述的第一条件可知，UL MAC PDU中包括的逻辑信道的最高优先级高于第一阈值表示的优先级，也可以理解为，UL MAC PDU中包括的逻辑信道的最高优先级的取值小于第一阈值。 UL BSR MAC CE对应的优先级高于第一阈值表示的优先级，也可以理解为，UL BSR MAC CE对应的优先级的取值小于第一阈值。
同理，侧行链路逻辑信道的优先级也可以用数值表示，而且数值越小时，可表示对应的优先级越高。如此，结合上文中所述的第二条件可知，SL BSR MAC CE对应的优先级高于第二阈值表示的优先级，也可以理解为，SL BSR MAC CE对应的优先级的取值小于第二阈值。SL SR对应的优先级高于第二阈值表示的优先级，也可以理解为，SL SR对应的优先级的取值小于第二阈值。
或者，在另一种可能的设计中，第一阈值和第二阈值也可以采用优先级列表的形式表示。即第一阈值可对应一个逻辑信道的优先级列表，该优先级列表中包括比第一阈值表示的优先级更高的其他所有逻辑信道优先级。如此，判断某一优先级是否大于第一阈值表示的优先级，可以为判断该优先级是否在该第一阈值对应的逻辑信道的优先级列表中。
同理，第二阈值可对应一个侧行链路逻辑信道的优先级列表，该优先级列表中包括比第二阈值表示的优先级更高的其他所有侧行链路逻辑信道优先级。如此，判断某一优先级是否大于第二阈值表示的优先级，可以为判断该优先级是否在该第二阈值对应的侧行链路逻辑信道的优先级列表中。
需要说明的是，本申请实施例中的第一阈值和第二阈值可以是协议预定的，也可以是网络设备为该终端设备配置的。所述“预定义”可以理解为定义、预先定义、存储、预存储、预协商、预配置、固化或预烧制。所述网络设备为终端设备配置可以理解为预配置，或者网络设备通过高层信令(例如RRC信令、MAC信令或物理层信令)、下行控制信息(downlink control information，DCI)、系统广播消息等多种方式将上述第一阈值和第二阈值发送给终端设备。可选地，第一阈值和第二阈值的发送方式可以相同，也可以不相同，第一阈值和第二阈值可在同一条消息中发送，也可以在不同的消息中发送，本申请并不限定。
请参考图3，为本申请实施例提供的一种通信方法的具体示例。如上文所述，在上行链路中，终端设备可以通过PUSCH信道发送UL MAC PDU，也可以通过PUCCH信道发送SR、CSI和ACK/NACK等信息。在具体的应用场景中，终端设备可能同时发送PUSCH和PUCCH，也可能仅发送PUSCH，或者仅发送PUCCH。因此，根据上行链路中实际发送的是PUSCH，还是PUCCH，以及PUSCH或PUCCH中实际承载的内容，可存在如图3中所示的5种优先级比较场景。可以理解，针对图3中所示的不同的优先级比较场景，终端设备在判断条件集合中的各项条件是否满足时，选择的子条件可以不同。
实施例二
请参考图4，为本申请实施例提供的一种通信方法的流程示意图，该方法具体包括如下的步骤S401至步骤S402：
步骤S401、终端设备同时存在上行链路调度请求UL SR的发送和侧行链路调度请求SL SR的发送。
所述UL SR和SL SR均在上行链路中的PUCCH信道上发送，其中，UL SR是指上行链路逻辑信道触发的调度请求，SL SR是指侧行链路逻辑信道触发的调度请求。
在步骤S401中，终端设备可确定同时存在UL SR的发送和SL SR的发送。所述同时存在UL SR的发送和SL SR的发送可以为，UL SR占用的时域资源与SL SR占用的时域资源存在部分或全部重叠。
在一种可能的设计中，可以不仅同时存在UL SR的发送和SL SR的发送，而且UL SR的发送和SL SR的发送之间还存在冲突。由于UL SR和SL SR均在上行链路中发送，因此该发送冲突属于Uu接口内PUCCH信道传输资源之间的冲突。具体的，UL SR的发送和SL SR的发送存在冲突的场景可以为，UL SR的发送使用的时域资源与SL SR的发送使用的时域资源存在部分或全部重叠，而且UL SR的发送与SL SR的发送共享/使用相同的载波。或者，UL SR的发送和SL SR的发送存在冲突的场景也可以为，UL SR的发送使用的时域资源与SL SR的发送使用的时域资源存在部分或全部重叠，UL SR的发送与SL SR的发送使用不同的载波，但是共享/使用相同的发送链Tx chain和功率预算power budget。
步骤S402、在UL SR对应的优先级低于或等于第一阈值表示的优先级，且SL SR对应的优先级高于第二阈值表示的优先级的情况下，终端设备发送SL SR；或者，在UL SR对应的优先级高于第一阈值表示的优先级，或所述SL SR对应的优先级低于或等于第二阈值表示的优先级的情况下，终端设备发送UL SR。
所述步骤S402也可以理解为，在UL SR对应的优先级高于第一阈值表示的优先级，或是SL SR对应的优先级低于或等于第二阈值表示的优先级的情况下，终端设备优先发送UL SR。在UL SR对应的优先级低于或等于第一阈值表示的优先级，且SL SR对应的优先级高于第二阈值表示的优先级的情况下，终端设备优先发送SL SR。
本申请实施例中，终端设备优先发送UL SR是指，终端设备只发送UL SR，不再发送SL SR，或者，终端设备同时发送UL SR和SL SR，但是降低SL SR的发送功率，或者终端设备先发送UL SR，后发送SL SR。类似的，终端设备优先发送SL SR是指，终端设备只发送SL SR，不再发送UL SR，或者，终端设备同时发送UL SR和SL SR，但是降低UL SR的发送功率，或者终端设备先发送SL SR，后发送UL SR。
需要说明的是，本申请实施例中，UL SR对应的优先级可以为触发该UL SR的逻辑信道的优先级。可选地，UL SR对应的优先级可以为触发该UL SR的逻辑信道的最高优先级。可选地，触发该UL SR的逻辑信道为能够关联到这个UL SR对应的PUCCH资源的逻辑信道。SL SR对应的优先级为可以触发该SL SR的侧行链路逻辑信道的优先级。可选地，SL SR对应的优先级为可以触发该SL SR的侧行链路逻辑信道的最高优先级。可选地，触发该SL SR的侧行链路逻辑信道为能够关联到这个SL SR对应的PUCCH资源的侧行链路逻辑信道。所述侧行链路逻辑信道的优先级也可以为PQI的优先级(priority level)。
上述第一阈值和第二阈值可以用数值表示，也可以用逻辑信道优先级列表或侧行链路逻辑信道优先级列表表示。而且第一阈值和第二阈值可以是协议预定义的，也可以是网络设备配置的。第一阈值和第二阈值的具体实施方式可参见步骤S202中的描述，在此不再赘述。
应理解，上述步骤S402中提供的技术方案可以应用在同时存在UL SR的发送和SL SR的发送的场景下，也可以应用在同时存在UL SR的发送和SL SR的发送，且UL SR的发送与SL SR的发送存在冲突的场景下。在这两种场景下，终端设备也可以将UL SR对应的优先级与SL SR对应的优先级进行直接比较，从而确定是优先进行UL SR的发送，还是优先进行SL SR的发送。但是这要求终端设备预先配置好逻辑信道的优先级和侧行链路逻辑信道的优先级之间的映射关系。
还应理解，本申请实施例中，当上行链路中的还可能同时存在UL ACK/NACK和SL ACK/NACK的发送，可以采用如步骤S402中类似的方式来确定如何进行发送。
示例性的，对于同时存在SL ACK/NACK的发送和UL ACK/NACK的发送时，在UL ACK/NACK对应的优先级低于或等于第一阈值表示的优先级，且SL ACK/NACK对应的优先级高于第二阈值表示的优先级的情况下，终端设备发送SL ACK/NACK；或者，在UL ACK/NACK对应的优先级高于第一阈值表示的优先级，或所述SL ACK/NACK对应的优先级低于或等于第二阈值表示的优先级的情况下，终端设备发送UL ACK/NACK。
所述UL ACK/NACK反馈对应的优先级可以为UL ACK/NACK反馈所关联的下行链路媒介访问协议数据单元(downlink medium access protocol data unit，DL MAC PDU)或传输块(transport block，TB)包括的逻辑信道的优先级。可选地，该UL ACK/NACK反馈对应的优先级可以为UL ACK/NACK反馈所关联的DL MAC PDU或TB包括的逻辑信道的最高优先级。
所述SL ACK/NACK反馈对应的优先级可以为SL ACK/NACK反馈所关联的SL MAC PDU或TB包括的侧行链路逻辑信道的优先级。可选地，该SL ACK/NACK反馈对应的优先级可以为SL ACK/NACK反馈所关联的SL MAC PDU或TB包括的侧行链路逻辑信道的最高优先级。
上述第一阈值和第二阈值可以用数值表示，也可以用逻辑信道优先级列表或侧行链路逻辑信道优先级列表表示。而且第一阈值和第二阈值可以是协议预定义的，也可以是网络设备配置的。第一阈值和第二阈值的具体实施方式可参见步骤S202中的描述，在此不再赘述。
应理解，上述提供的技术方案可以应用在同时存在UL ACK/NACK的发送和SL ACK/NACK的发送的场景下，也可以应用在同时存在UL ACK/NACK的发送和SL ACK/NACK的发送，且UL ACK/NACK的发送与SL ACK/NACK的发送存在冲突的场景下。在这两种场景下，终端设备也可以将UL ACK/NACK对应的优先级与SL ACK/NACK对应的优先级进行直接比较，从而确定是优先进行UL ACK/NACK的发送，还是优先进行SL ACK/NACK的发送。但是这要求终端设备预先配置好逻辑信道的优先级和侧行链路逻辑信道的优先级之间的映射关系。
实施例三
请参考图5，为本申请实施例提供的一种通信方法的流程示意图，该方法具体包括如下的步骤S501至步骤S502：

在步骤S501中，终端设备可确定同时存在UL MAC PDU的发送和SL SR的发送。所述同时存在UL MAC PDU的发送和SL SR的发送可以为，UL MAC PDU占用的时域资源与SL SR占用的时域资源存在部分或全部重叠。
在一种可能的设计中，可以不仅同时存在UL MAC PDU的发送和SL SR的发送，而且UL MAC PDU的发送和SL SR的发送之间还存在冲突。由于UL MAC PDU和SL SR均在上行链路中发送，因此该发送冲突属于Uu接口内PUSCH与PUCCH之间的发送冲突。 具体的，UL MAC PDU的发送和SL SR的发送存在冲突的场景可以为，UL MAC PDU的发送使用的时域资源与SL SR的发送使用的时域资源存在部分或全部重叠，而且UL MAC PDU的发送与SL SR的发送共享/使用相同的载波。或者，UL MAC PDU的发送和SL SR的发送存在冲突的场景也可以为，UL MAC PDU的发送使用的时域资源与SL SR的发送使用的时域资源存在部分或全部重叠，UL MAC PDU的发送与SL SR的发送使用不同的载波，但是共享/使用相同的发送链Tx chain和功率预算power budget。

实施例四
当前技术中，QoS参数和侧行链路无线承载SLRB的映射关系以及SLRB配置可以包括在网络设备在系统信息块(system information block，SIB)消息中，然而SIB消息大小有限，不能包括所有的QoS参数组合，甚至不能包括保证流量比特率GBR业务对应的保证流量比特率(guaranteed flow bit rate，GFBR)和最大流量比特率(maximum flow bit rate，MFBR)参数，如果终端设备继续使用SIB的配置来进行侧行链路的通信，可能会使得一些侧行链路的业务传输的QoS需求无法满足。
有鉴于此，本申请还提供了一种无线资源控制(radio resource control，RRC)连接建立或连接恢复的通信方法。
在满足下述条件(1)至(9)中的一项或多项的情况下，终端设备发起与网络设备之间的RRC连接建立或RRC连接恢复：

上述各项条件中所涉及到的关联非标准的PC5口第五代通信系统服务质量标识(PC5 5G quality of service identifier，PQI)参数也可以理解为关联具体的资源类型Resource Type(GBR,Delay critical GBR or Non-GBR)、优先等级Priority Level、包延迟预算(Packet Delay Budget，PDB)、包错误率(Packet Error Rate，PER)、平均窗口Averaging window(for GBR  and Delay-critical GBR resource type only)、最大数据突发量Maximum Data Burst Volume(for Delay-critical GBR resource type only)参数中的一种或多种。

实施例五
当前技术中，在一些场景中，如终端设备检测到与网络设备之间的接口无线链路失败(Radio link failure，RLF)情况下，终端设备需要与其他终端设备竞争特殊资源池(exceptional pool)中的资源进行侧行链路传输，从而可能会造成终端设备竞争不到资源的情况，影响业务连续性。
有鉴于此，本申请还提供了一种通信方法。在终端设备检测发生RLF的情况下，或者，在终端设备检测到与网络设备之间的接口发生波束失败的情况下，或者，在终端设备检测与网络设备之间的接口的波束失败的过程中，或者终端设备检测到与网络设备之间的接口发生物理层链路问题的情况下，或者，在终端设备同步到全球导航卫星系统(global navigation satellite system，GNSS)的情况下，若终端设备已经被配置了配置授权(configured grant)，则使用该configured grant进行侧行链路传输。可选的，除了configured grant，终端设备还可以继续使用已经配置的侧行链路无线承载SLRB配置、发送资源池Tx resource pool、接收资源池Rx resource pool、特殊资源池exceptional pool、同步配置、物理层参数配置中的一种或多种。
可选地，若终端设备没有被配置configured grant，则使用特殊资源池(exceptional pool)进行侧行链路传输。
可选地，configured grant包括configured grant type 1和configured grant type 2。对于configured grant type 1，可以直接使用；对于configured grant type 2且已经通过下行控制信息(downlink control inforamtion，DCI)激活，可以继续使用。

实施例六
当前技术中，终端设备在逻辑信道优先级(Logical Channel Prioritization，LCP)过程中，不包括用于填充的上行链路缓存状态报告媒体接入控制单元non-padding UL BSR MAC CE(MAC control element for BSR,with exception of BSR included for padding)的优先级始终高于不包括用于填充的侧行链路缓存状态报告媒体接入控制单元non-padding SL BSR MAC CE(MAC control element for Sidelink BSR,with exception of Sidelink BSR included for padding)。non-padding UL BSR可能由低优先级的增强型移动宽带(enhanced mobile broadband，eMBB)业务触发，non-padding SL BSR可能由高优先级的超可靠低延时通信(ultra reliable low latency communication，URLLC)业务触发，而按照现有技术在LCP中non-padding UL BSR MAC CE的优先级一定高于non-padding SL BSR MAC CE，如果上行资源不够大的情况下，会导致non-padding SL BSR MAC CE不能够包括在当前的UL MAC PDU中发送给网络设备从而无法及时获取侧行链路的传输资源，进一步影响侧行链路上的URLLC业务传输。
有鉴于此，本申请还提供了一种通信方法。
终端设备确定在LCP过程中non-padding UL BSR MAC CE和non-padding SL BSR MAC CE的相对优先级。
在non-padding UL BSR MAC CE对应的优先级不高于第一阈值表示的优先级或者不在第一优先级列表中的情况下，且non-padding SL BSR MAC CE对应的优先级高于第二阈值表示的优先级或者在第二优先级列表中的情况下，终端设备确定non-padding SL BSR MAC CE在LCP过程中的优先级高于non-padding UL BSR MAC CE；否则，终端设备确定non-padding UL BSR MAC CE在LCP过程中的优先级高于non-padding SL BSR MAC CE。
可选地，non-padding UL BSR MAC CE对应的优先级为触发UL BSR的上行链路逻辑信道的最高优先级；non-padding SL BSR MAC CE对应的优先级为触发SL BSR的侧行链路逻辑信道的最高优先级。
可选地，non-padding UL BSR MAC CE对应的优先级为上行链路存在待传输数据的逻辑信道的最高优先级(UL MAC PDU组包时，或者UL MAC PDU传输时)；non-padding SL BSR MAC CE对应的优先级为侧行链路存在待传输数据的侧行链路逻辑信道的最高优先级(UL MAC PDU组包时，或者UL MAC PDU传输时)。
可选地，non-padding UL BSR MAC CE对应的优先级为non-padding UL BSR MAC CE包括的缓冲区大小BS所关联的逻辑信道的最高优先级；non-padding SL BSR MAC CE对应的优先级为non-padding SL BSR MAC CE包括的缓冲区大小BS所关联的侧行链路逻辑信道的最高优先级。
可选的，触发non-padding UL BSR的逻辑信道为满足这个non-padding UL BSR MAC CE关联的UL-SCH资源的LCP restriction的逻辑信道，上行链路中存在待传输数据的逻辑信道为满足这个non-padding UL BSR MAC CE关联的UL-SCH资源的LCP restriction的逻辑信道。
可选的，触发non-padding SL BSR的逻辑信道为满足这个non-padding SL BSR MAC CE关联的UL-SCH资源的LCP restriction的逻辑信道，侧行链路中存在待传输数据的侧行链路逻辑信道为满足这个non-padding SL BSR MAC CE关联的UL-SCH资源的LCP restriction的侧行链路逻辑信道。
可选地，non-padding UL BSR MAC CE对应的优先级不高于第一阈值表示的优先级可以是non-padding UL BSR MAC CE对应的优先级值大于或等于第一阈值；non-padding SL BSR MAC CE对应的优先级高于第二阈值表示的优先级可以是non-padding UL BSR MAC CE对应的优先级值小于第二阈值。
