Description

通信优先级确定方法及装置
本申请要求在2020年3月28日提交中华人民共和国知识产权局、申请号为202010232424.6、发明名称为“通信优先级确定方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信优先级确定方法及装置。
背景技术
半双工(half duplex，HD)是一种可以通过简化射频实现来降低成本和功耗的双工手段。例如，HD终端由于不需要同时发送和接收信号，既可以降低终端的实现成本，也可以降低终端的功耗。在无线通信网络中，终端可以与网络设备进行下行通信，例如终端可以接收来自网络设备的下行控制信息(downlink control information，DCI)和/或下行数据。终端还可以与网络设备进行自主的上行通信，即终端无需根据网络设备的调度即可发起与网络设备的上行通信，这种自主的上行通信例如可以包括上行配置授权(configured grant，CG)传输和/或随机接入前导的发送。
HD终端的下行通信与上行通信无法同时进行，也就是说，HD终端的下行通信与上行通信需要以时分的方式进行。但是，由于网络设备无法预测终端何时会发起自主的上行通信，HD终端与网络设备之间的下行通信和自主上行通信可能产生冲突，从而导致上下行传输效率和容量的下降。因此，如何能够减少HD终端与网络设备的下行通信和自主上行通信之间的冲突，进而提高上下行传输效率和容量，成为亟需解决的问题。
发明内容
本申请实施例提供一种通信优先级确定方法及装置。
第一方面，本申请实施例提供一种通信方法，该方法可以由终端执行，也可以由终端的部件(例如处理器、芯片、或芯片系统等)执行，包括：获得下行通信与上行通信之间的目标优先级信息，并根据该目标优先级信息在时间单元上进行下行通信或上行通信。可选地，该上行通信包括上行CG传输和/或随机接入前导的发送，上行CG传输例如可以承载在物理上行共享信道(physical uplink shared channel，PUSCH)上，随机接入前导例如可以承载在物理随机接入信道(physical random access channel，PRACH)上。可选地，该下行通信包括DCI的接收和/或下行数据的接收，DCI例如可以承载在物理下行控制信道(physical downlink control channel，PDCCH)上，下行数据例如可以承载在物理下行共享信道(physical downlink shared channel，PDSCH)上。可选地，上述时间单元的数量为一个或多个，终端可以根据目标优先级信息在该一个或多个时间单元上进行下行通信或上行通信，其中，一个时间单元包括一个或多个时域符号、一个或多个时隙、一个或多个子帧、或者一个或多个无线帧。
通过获取下行通信与上行通信之间的目标优先级信息，并依据该目标优先级信息在时间单元上执行下行通信或上行通信，从而减少了HD终端或具有HD能力的终端与网络 设备的下行通信和自主上行通信之间的冲突，进而提高上下行传输的效率和容量。
结合第一方面，在第一方面的某些实施方式中，在进行下行通信或上行通信的时间单元上配置有下行通信和上行通信。换句话说，终端在该配置下的时间单元上可能会存在下行通信需求，也可能会存在上行通信需求，还有可能同时存在下行通信和上行通信的需求。但是，由于HD终端的下行通信与上行通信无法同时进行，因此上述方法中的目标优先级信息，终端能够获得时间单元上下行通信与上行通信间的优先级，从而在该时间单元上进行下行通信与上行通信中的一种，减少了下行通信和上行通信之间的冲突，进而提高上下行传输的效率和容量。可以理解，该时间单元上的下行通信和上行通信可以是预定义的，也可以是由网络设备为终端配置的。可选地，在时间单元上配置的下行通信和上行通信可以多于两套。可选地，不同时间单元上下行通信与上行通信间的目标优先级信息可以独立配置或指示。
结合第一方面，在第一方面的某些实施方式中，可根据目标优先级信息指示的具体内容在时间单元上进行下行通信或上行通信。当该目标优先级信息指示下行通信的优先级高于上行通信的优先级时，则在上述时间单元上进行下行通信。当该目标优先级信息指示上行通信的优先级高于下行通信的优先级时，则在上述时间单元上进行上行通信。可选地，目标优先级信息指示在该时间单元上下行通信的优先级高于上行通信的优先级，或者，目标优先级信息指示在该时间单元上上行通信的优先级高于下行通信的优先级。通过这一实施方式，能够在上下行通信中优先进行优先级较高的业务服务，从而能够保障更高优先级业务的服务需求。
结合第一方面，在第一方面的某些实施方式中，通过接收来自网络设备的第一指示信息来获得前述的目标优先级信息。
可选地，第一指示信息包括第一取值或第二取值，第一取值与第二取值不同。当第一指示信息包括第一取值时，能够根据该第一取值获得的目标优先级信息指示下行通信的优先级高于上行通信的优先级。当第一指示信息包括第二取值时，能够根据该第二取值获得的目标优先级信息指示上行通信的优先级高于下行通信的优先级。该第一取值和第二取值可以是枚举值、整数值或二进制数值。
通过上述实施方式，网络设备能够更好的控制终端上下行通信的优先级。由于网络设备维护有网络中大量终端的业务需求等需求信息，因此由网络设备控制终端上下行通信的优先级，能够以集中管理的方式优化网络中的上下行传输，从而提升网络资源的使用效率。
结合第一方面，在第一方面的某些实施方式中，通过向网络设备发送第二指示信息，来向网络设备指示下行通信与上行通信之间的候选优先级信息。该候选优先级信息可理解为终端期望的下行通信与上行通信之间的目标优先级信息。终端将该候选优先级信息上报给网络设备，可以理解为终端向网络设备请求该候选优先级信息。网络设备接收到该候选优先级信息后，会给终端下发最终的优先级信息(即目标优先级信息)，用于控制终端的上下行传输。
该候选优先级信息与目标优先级信息可以相同，也可以不同。网络设备可以决定将终端请求的候选优先级信息作为目标优先级信息，此时候选优先级信息与目标优先级信息相同。网络设备也可以决定不将终端请求的候选优先级信息作为目标优先级信息，而是给终端下发一个新的目标优先级信息，此时候选优先级信息与目标优先级信息不同。
通过上述方式，终端能够向网络设备请求下行通信与上行通信的目标优先级信息，由于终端相比网络设备对于其自主上行通信的需求有更多的了解，因此由终端先向网络设备建议终端上下行通信的优先级，再由网络设备参考终端的建议，做出上下行通信的优先级的决策，能够优化网络中的上下行传输，从而提升网络资源的使用效率。
结合第一方面，在第一方面的某些实施方式中，通过向网络设备发送第三指示信息来向网络设备指示下行通信与上行通信的目标优先级信息。可选地，在发送第三指示信息前，可以确定该目标优先级信息，例如根据上下行通信的需求程度、或紧急程度等因素确定该目标优先级信息。
可选地，第三指示信息包括第三取值或第四取值，第三取值与第四取值不同。第三取值用于指示下行通信的优先级高于上行通信，第四取值用于指示上行通信的优先级高于下行通信。该第三取值和第四取值可以是枚举值、整数值或二进制数值。
通过该实施方法，终端或终端的部件能够依据自身需求选择上下行通信的优先级，能够以分布式的方式优化网络中的上下行传输，从而提升网络资源的使用效率。
结合第一方面，在第一方面的某些实施方式中，可依据对下行通信的预期和/或与上行通信对应的服务质量(quality of service，QoS)确定该目标优先级信息。
例如，当上行通信对应的时延预算(一种QoS)大于某个门限，或者当上行通信对应的优先级(另一种QoS)低于某个门限时，确定下行通信的优先级高于上行通信。当上行通信对应的时延预算小于某个门限，或者当上行通信对应的优先级高于某个门限时，确定上行通信的优先级高于下行通信。
又例如，当终端期望获得来自网络设备的下行信息时，确定下行通信的优先级高于上行通信。当终端未期望获得来自网络设备的下行信息时，确定上行通信的优先级高于下行通信。
通过上述实施方式能够降低获得目标优先级信息时的信令交互和开销，并且提供了更加灵活与动态的优先级调整方式。
结合第一方面，在第一方面的某些实施方式中，可依据搜索空间的类型确定该目标优先级信息。
例如，当在时间单元上为承载DCI的PDCCH配置的搜索空间为公共搜索空间时，终端可确定在该时间单元上DCI接收的优先级高于上行通信。当在时间单元上为承载DCI的PDCCH配置的搜索空间为特定搜索空间(例如终端特定搜索空间)时，终端可确定在该时间单元上上行通信的优先级高于DCI的接收。
通过上述实施方式能够降低获得目标优先级信息时的信令交互和开销，并且提供了更加灵活与动态的优先级调整方式。
第二方面，本申请实施例提供一种通信方法，该方法可以由网络设备执行，也可以由网络设备的部件(例如处理器、芯片、或芯片系统等)执行，包括：接收来自终端的第二指示信息，并向终端发送第一指示信息，第二指示信息用于指示下行通信与上行通信之间的候选优先级信息，第一指示信息用于指示下行通信与上行通信之间的目标优先级信息，目标优先级信息与候选优先级信息指示的内容相同或不同，且目标优先级信息用于指示在时间单元上进行下行通信或上行通信。可选地，该上行通信包括上行CG传输和/或随机接入前导的发送，上行CG传输例如可以承载在PUSCH上，随机接入前导例如可以承载在PRACH上。可选地，该下行通信包括DCI的接收和/或下行数据的接收，DCI例如可以承载在PDCCH上，下行数据例如可以承载在PDSCH上。可选地，上述时间单元的数量为一个或多个，其中，一个时间单元包括一个或多个时域符号、一个或多个时隙、一个或多个子帧、或者一个或多个无线帧。可选地，第一指示信息包括第一取值或第二取值，第一取值用于指示下行通信的优先级高于上行通信的优先级，第二取值用于指示上行通信的优先级高于下行通信的优先级。可选地，上述时间单元上配置有下行通信和上行通信。
通过上述方式，终端能够向网络设备请求下行通信与上行通信的目标优先级信息，由于终端相比网络设备对于其自主上行通信的需求有更多的了解，因此由终端先向网络设备建议终端上下行通信的优先级，再由网络设备参考终端的建议，做出上下行通信的优先级的决策，能够优化网络中的上下行传输，从而提升网络资源的使用效率。
第三方面，本申请实施例提供一种装置，可以实现上述第一方面、或第一方面任一种可能的实施方式中的方法。该装置包括用于执行上述方法的相应的单元或部件。该装置包括的单元可以通过软件和/或硬件方式实现。该装置例如可以为终端、或者为可支持终端实现上述方法的芯片、芯片系统、或处理器等。

CU的功能可以由一个实体来实现，也可以进一步将控制面(CP)和用户面(UP)分离，即CU的控制面(CU-CP)和用户面(CU-UP)可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。

终端是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的终端、车载终端设备、无人驾驶(self driving)中的终端、辅助驾驶中的终端、远程医疗(remote medical)中的终端、智能电网(smart grid)中的终端、运输安全(transportation safety)中的终端、智慧城市(smart city)中的终端、智慧家庭(smart home)中的终端等等。本申请的实施例对应用场景不做限定。终端有时也可以称为终端设备、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、机器终端、UE代理或UE装置等。终端可以是固定的，也可以是移动的。
作为示例而非限定，在本申请中，终端可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
在本申请中，终端可以是物联网(internet of things，IoT)系统中的终端，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。本申请中的终端可以是机器类型通信(machine type communication，MTC)中的终端。本申请的终端可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元，车辆通过内置的所述车载模块、车载模组、车载部件、车载芯片或者车载单元可以实施本申请的方法。因此，本申请实施例可以应用于车联网，例如车辆外联(vehicle to everything，V2X)、车间通信长期演进技术(long term evolution vehicle，LTE-V)、车到车(vehicle to vehicle，V2V)等。
半双工(half duplex，HD)是一种可以通过简化射频实现来降低成本和功耗的双工手段。 例如，HD终端(也可称为HD能力终端、或具有HD能力的终端)由于不需要同时发送和接收信号，既可以降低终端的实现成本，也可以降低终端的功耗。在无线通信网络中，终端可以与网络设备进行下行通信，例如终端可以接收来自网络设备的下行控制信息(downlink control information，DCI)和/或下行数据。终端还可以与网络设备进行自主的上行通信，即终端无需根据网络设备的调度即可发起与网络设备的上行通信，这种自主的上行通信例如可以包括上行配置授权(configured grant，CG)传输和/或随机接入前导的发送。
HD终端的下行通信与上行通信无法同时进行，也就是说，HD终端的下行通信与上行通信需要以时分的方式进行。但是，由于网络设备无法预测终端何时会发起自主的上行通信，HD终端与网络设备之间的下行通信和自主上行通信可能产生冲突，从而导致上下行传输效率和容量的下降。因此，如何能够减少HD终端或者具有HD能力的终端与网络设备的下行通信和自主上行通信之间的冲突，进而提高上下行传输效率和容量，成为亟需解决的问题。
本申请提供的实施例中设计一种优先级确定的方法，在该方法中通过获取下行通信与上行通信之间的目标优先级信息，并依据该目标优先级信息在时间单元上执行下行通信或上行通信，从而减少HD终端或具有HD能力的终端与网络设备的下行通信和自主上行通信之间的冲突，进而提高上下行传输的效率和容量。
下面以具体实施例结合附图对本申请的技术方案进行详细说明。下述实施例和实施方式可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。应理解，本申请中所解释的功能可以通过独立硬件电路、使用结合处理器/微处理器或通用计算机而运行的软件、使用专用集成电路，和/或使用一个或多个数字信号处理器来实现。当本申请描述为方法时，其还可以在计算机处理器和被耦合到处理器的存储器中实现。
图3为本申请实施例提供的一种通信方法300的流程图。该方法可以由终端执行，也可以由终端的芯片、芯片系统、或处理器等执行，本申请后续以终端为例进行描述。如图3所示，该方法300包括310部分和320部分。该方法300可以由HD终端(例如半双工频分双工(half deplex frequency division duplex，HD-FDD)终端)执行，也可以由具有HD能力的终端(例如具有HD-FDD能力的终端)执行。
310部分：终端获得下行通信与上行通信之间的目标优先级信息。可以理解的是，优先级信息也可被称为指示信息、冲突信息、上下行指示信息、冲突优先级信息、或冲突处理指示信息等，本申请对其名称不做限定。
320部分：终端根据目标优先级信息，在时间单元上进行下行通信或上行通信。可选地，该上行通信包括上行CG传输和/或随机接入前导的发送，上行CG传输例如可以承载在物理上行共享信道(physical uplink shared channel，PUSCH)上，随机接入前导例如可以承载在物理随机接入信道(physical random access channel，PRACH)上。可选地，该下行通信包括DCI的接收和/或下行数据的接收，DCI例如可以承载在物理下行控制信道(physical downlink control channel，PDCCH)上，下行数据例如可以承载在物理下行共享信道(physical downlink shared channel，PDSCH)上。可选地，上述时间单元的数量为一个或多个，终端可以根据目标优先级信息在该一个或多个时间单元上进行下行通信或上行通信，其中，一个时间单元包括一个或多个时域符号、一个或多个时隙、一个或多个子帧、或者一个或多个无线帧。
可以理解，本申请中的“接收”也可被替换为“检测”、“监听”、或“监测”等。
在该方法300中，终端通过获取下行通信与上行通信之间的目标优先级信息，并依据该目标优先级信息在时间单元上执行下行通信或上行通信，从而减少了HD终端或具有 HD能力的终端与网络设备的下行通信和自主上行通信之间的冲突，进而提高上下行传输的效率和容量。
在方法300的一种可能的实施方式中，在进行下行通信或上行通信的时间单元上配置有下行通信和上行通信。换句话说，终端在该配置下的时间单元上可能会存在下行通信需求，也可能会存在上行通信需求，还有可能同时存在下行通信和上行通信的需求。但是，由于HD终端的下行通信与上行通信无法同时进行，因此借助方法300中的目标优先级信息，终端能够获得时间单元上下行通信与上行通信间的优先级，从而在该时间单元上进行下行通信与上行通信中的一种，减少了下行通信和上行通信之间的冲突，进而提高上下行传输的效率和容量。可以理解，该时间单元上的下行通信和上行通信可以是预定义的，也可以是由网络设备为终端配置的(例如网络设备通过高层信令为终端配置的)。
以时间单元上配置DCI为例，说明一种下行通信在时间单元上的配置。DCI可以由PDCCH承载，因此时间单元上配置DCI也可以理解为时间单元上配置PDCCH。PDCCH的配置可以由控制资源集合(control resource set，CORESET)的配置和/或搜索空间(search space)的配置确定。通过CORESET的配置和/或搜索空间的配置，终端能够确定PDCCH被配置在哪个或哪些时间单元上。
以时间单元上配置上行CG传输为例，说明一种上行通信在时间单元上的配置。通过来自网络设备的高层参数(例如参数ConfiguredGrantConfig)，终端能够确定上行CG传输被配置在哪个或哪些时间单元上。
再以时间单元上配置随机接入前导为例，说明另一种上行通信在时间单元上的配置。通过来自网络设备的系统信息，终端能够确定随机接入前导被配置在哪个或哪些时间单元上。
在320部分的一种可能的实施方式中，终端可根据目标优先级信息指示的具体内容在时间单元上进行下行通信或上行通信。当该目标优先级信息指示下行通信的优先级高于上行通信的优先级时，终端在上述时间单元上进行下行通信。当该目标优先级信息指示上行通信的优先级高于下行通信的优先级时，终端在上述时间单元上进行上行通信。可选地，目标优先级信息指示在该时间单元上下行通信的优先级高于上行通信的优先级，或者，目标优先级信息指示在该时间单元上上行通信的优先级高于下行通信的优先级。通过这一实施方式，能够在上下行通信中优先进行优先级较高的业务服务，从而能够保障更高优先级业务的服务需求。
以下行通信包含DCI1的接收、上行通信包含上行CG传输、以及时间单元为时隙为例，结合图4A说明本申请实施例的一种具体的实现。图4A中示意了20个索引由0至19的时隙。其中，配置示意表示的是DCI1和CG在这20个时隙上的配置情况：
●时隙0、2、6、8、10、12、16和18上配置有DCI1。
●时隙9和19上配置有上行CG。
●时隙4和14上配置有DCI1和上行CG。
其中，通信示意表示的是终端在各时隙上的通信情况：
●时隙0、2、6、8、10、12、16和18上配置有DCI1，未配置上行CG。因此终端在时隙0、2、6、8、10、12、16和18上进行DCI1的接收或检测。
●时隙9和19上配置有上行CG，未配置DCI1。因此终端在时隙9和19上进行上行CG传输。
●时隙4和14上同时配置有DCI1和上行CG。终端获得DCI1的接收与上行CG传输之间的目标优先级信息，依据该目标优先级信息确定上行CG传输的优先级高于 DCI1的接收，因此终端在时隙4和14上进行上行CG传输。
以下行通信包含DCI1的接收、上行通信包含上行CG传输、以及时间单元为时隙为例，结合图4B说明本申请实施例的另一种具体的实现。与图4A示意的实现相比，图4B的区别在于，终端获得DCI1的接收与上行CG传输之间的目标优先级信息，依据该目标优先级信息确定DCI1接收的优先级高于上行CG传输，因此终端在时隙4和14上进行DCI1的接收。
可选地，在时间单元上配置的下行通信和上行通信可以多于两套。以下行通信包含DCI1和DCI2的接收、上行通信包含上行CG传输、以及时间单元为时隙为例，结合图5说明本申请实施例的另一种具体的实现。图5中示意了20个索引由0至19的时隙。其中，配置示意表示的是DCI1、DCI2和CG(共三套)在这20个时隙上的配置情况：
●时隙0、2、6、8、10、12、16和18上配置有DCI1。
●时隙19上配置有上行CG。
●时隙4和14上配置有DCI1和上行CG。
●时隙9上配置有DCI2和上行CG。
其中，通信示意表示的是终端在各时隙上的通信情况：
●时隙0、2、6、8、10、12、16和18上配置有DCI1，未配置上行CG和DCI2。因此终端在时隙0、2、6、8、10、12、16和18上进行DCI1的接收或检测。
●时隙19上配置有上行CG，未配置DCI1和DCI2。因此终端在时隙19上进行上行CG传输。
●时隙4和14上同时配置有DCI1和上行CG，未配置DCI2。终端获得DCI1的接收与上行CG传输之间的目标优先级信息，依据该目标优先级信息确定上行CG传输的优先级高于DCI1的接收，因此终端在时隙4和14上进行上行CG传输。
●时隙9上同时配置有DCI2和上行CG，未配置DCI1。终端获得DCI2的接收与上行CG传输之间的目标优先级信息，依据该目标优先级信息确定DCI2接收的优先级高于上行CG传输，因此终端在时隙9上进行DCI2的接收或检测。
可选地，不同时间单元上下行通信与上行通信间的目标优先级信息可以独立配置或指示。在这种方案中，不同时间单元上下行通信与上行通信间的目标优先级信息可以相同也可以不同，终端可以获得不同时间单元上下行通信与上行通信间的目标优先级信息。以下行通信包含DCI1的接收、上行通信包含上行CG传输、以及时间单元为时隙为例，结合图6说明本申请实施例的另一种具体的实现。图6中示意了20个索引由0至19的时隙。其中，配置示意表示的是DCI1和CG在这20个时隙上的配置情况：
●时隙0、2、6、8、10、12、16和18上配置有DCI1。
●时隙9和19上配置有上行CG。
●时隙4和14上配置有DCI1和上行CG。
其中，通信示意表示的是终端在各时隙上的通信情况：
●时隙0、2、6、8、10、12、16和18上配置有DCI1，未配置上行CG。因此终端在时隙0、2、6、8、10、12、16和18上进行DCI1的接收或检测。
●时隙9和19上配置有上行CG，未配置DCI1。因此终端在时隙9和19上进行上行CG传输。
●时隙4上同时配置有DCI1和上行CG。终端获得时隙4上DCI1的接收与上行CG传输之间的目标优先级信息，依据该目标优先级信息确定时隙4上上行CG传输的优先级高于DCI1的接收，因此终端在时隙4上进行上行CG传输。
●时隙14上同时配置有DCI1和上行CG。终端获得时隙14上DCI1的接收与上行CG传输之间的目标优先级信息，依据该目标优先级信息确定时隙14上DCI1接收的优先级高于上行CG传输，因此终端在时隙14上进行DCI1的接收。
方法300的310部分可以有多种不同的实施方式，可以通过下述几种实施方法(实施方法1、实施方法2、实施方法3和实施方法4)获得下行通信与上行通信之间的目标优先级信息。
实施方法1：网络设备为终端指示或配置该目标优先级信息。
实施方法2：终端向网络设备指示该目标优先级信息，也可以理解为终端自主确定该目标优先级信息。
实施方法3：终端和网络设备依据对下行通信的预期和/或与上行通信对应的服务质量(quality of service，QoS)确定该目标优先级信息。
实施方法4：终端依据搜索空间的类型确定该目标优先级信息。这一实施方法主要针对下行通信包括DCI的接收。
下面分别描述310部分的上述几种不同的实施方法。
在310部分的实施方法1中，由网络设备为终端指示或配置目标优先级信息。图7为本实施方法的一种交互示意图。图7中以终端和网络设备作为该交互示意的执行主体为例来示意该通信方法，但本申请并不限制该交互示意的执行主体。例如，图7中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器等。例如，图7中的终端也可以是支持该终端实现该方法的芯片、芯片系统、或处理器等。图7中示意的方法700包括710部分和720部分。
710部分：网络设备向终端发送第一指示信息。相应地，终端接收来自网络设备的第一指示信息，并根据该第一指示信息获得前述的目标优先级信息。可选地，该第一指示信息由RRC信令、MAC控制元素(control element，CE)、或DCI承载。该710部分可以理解为方法300中310部分的实施方法1。
720部分：终端根据710部分获得的目标优先级信息，在时间单元上进行下行通信或上行通信。该720部分可以理解为方法300中的320部分。
通过该实施方法，网络设备能够更好的控制终端上下行通信的优先级。由于网络设备维护有网络中大量终端的业务需求等需求信息，因此由网络设备控制终端上下行通信的优先级，能够以集中管理的方式优化网络中的上下行传输，从而提升网络资源的使用效率。
在710部分的一种可能实施方式中，第一指示信息包括第一取值或第二取值，第一取值与第二取值不同。当第一指示信息包括第一取值时，终端根据该第一取值获得的目标优先级信息指示下行通信的优先级高于上行通信的优先级。当第一指示信息包括第二取值时，终端根据该第二取值获得的目标优先级信息指示上行通信的优先级高于下行通信的优先级。该第一取值和第二取值可以是枚举值、整数值或二进制数值，本申请实施例对此不做限定。
以该第一指示信息由RRC信令承载为例，RRC信令中可携带如下表1所示的信元：
表1
Figure PCTCN2021081595-appb-000001
其中，信元HD-FDD-Priority中包含的dci-cg-priority可以理解为第一指示信息。dci-cg-priority的取值为“DCI”或“CG”这两个枚举值中的一个：
当dci-cg-priority的取值为“DCI”时，表示DCI接收的优先级高于上行CG传输。当dci- cg-priority的取值为“CG”时，表示上行CG传输的优先级高于DCI的接收。或者，
当dci-cg-priority的取值为“DCI”时，表示DCI接收的优先级低于上行CG传输。当dci-cg-priority的取值为“CG”时，表示上行CG传输的优先级低于DCI的接收。
可以理解，本申请对信元以及信元中包含信息的名称的描述仅作为举例，并不限制其他可能的名称，只要信元以及信元中包含的信息所起功能与本申请中的一致，都应在本申请的保护范围内。
在另一个第一指示信息由RRC信令承载的示例中，RRC信令中可携带如下表2所示的信元：
表2
Figure PCTCN2021081595-appb-000002
其中信元SearchSpace包含了PDCCH的搜索空间的配置信息，而dci-cg-priority(第一指示信息)作为PDCCH搜索空间配置信息的一部分，dci-cg-priority的取值为“DCI”或“CG”这两个枚举值中的一个，用以指示配置在该搜索空间内的PDCCH(或PDCCH承载的DCI)与上行CG传输的目标优先级信息：
当dci-cg-priority的取值为“DCI”时，表示该搜索空间内PDCCH上DCI接收的优先级高于上行CG传输。当dci-cg-priority的取值为“CG”时，表示上行CG传输的优先级高于该搜索空间内PDCCH上DCI的接收。或者，
当dci-cg-priority的取值为“DCI”时，表示该搜索空间内PDCCH上DCI接收的优先级低于上行CG传输。当dci-cg-priority的取值为“CG”时，表示上行CG传输的优先级低于该搜索空间内PDCCH上DCI的接收。
通过在搜索空间配置信息中包含上述第一指示信息，能够独立地为不同搜索空间内PDCCH上的DCI接收配置与上行通信之间的优先级，从而使得上下行通信的优先级配置更加灵活，以适配不同的业务需求。
在另一个第一指示信息由RRC信令承载的示例中，RRC信令中可携带如下表3所示的信元：
表3
Figure PCTCN2021081595-appb-000003
其中，信元HD-FDD-Priority中包含的dci-cg-priority可以理解为第一指示信息。dci-cg-priority包含两个或更多个取值为“DCI”或“CG”枚举值，可分别指示两个或更多个时间单元上DCI接收与上行CG传输之间的目标优先级信息。参数maxCollision指示时间单元的个数。
通过第一指示信息指示多个时间单元上的目标优先级信息，能够独立地为不同时间单元配置目标优先级信息，从而使得不同时间单元上的上下行通信的优先级配置更加灵活，以适配不同的业务需求。
在方法700中还可以包括可选的730部分：终端向网络设备发送第二指示信息，该第二指示信息用于指示下行通信与上行通信之间的候选优先级信息。相应地，网络设备接收该第二指示信息。
该候选优先级信息可理解为终端期望的下行通信与上行通信之间的目标优先级信息。终端将该候选优先级信息上报给网络设备，可以理解为终端向网络设备请求该候选优先级信息。 网络设备接收到该候选优先级信息后，会给终端下发最终的优先级信息(即目标优先级信息)，用于控制终端的上下行传输。
该候选优先级信息与目标优先级信息可以相同，也可以不同。网络设备可以决定将终端请求的候选优先级信息作为目标优先级信息，此时候选优先级信息与目标优先级信息相同。网络设备也可以决定不将终端请求的候选优先级信息作为目标优先级信息，而是给终端下发一个新的目标优先级信息，此时候选优先级信息与目标优先级信息不同。
通过上述方式，终端能够向网络设备请求下行通信与上行通信的目标优先级信息，由于终端相比网络设备对于其自主上行通信的需求有更多的了解，因此由终端先向网络设备建议终端上下行通信的优先级，再由网络设备参考终端的建议，做出上下行通信的优先级的决策，能够优化网络中的上下行传输，从而提升网络资源的使用效率。
在310部分的实施方法2中，终端向网络设备指示该目标优先级信息，也可以理解为终端自主确定该目标优先级信息。图8为本实施方法的一种交互示意图。图8中以终端和网络设备作为该交互示意的执行主体为例来示意该通信方法，但本申请并不限制该交互示意的执行主体。例如，图8中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器等。例如，图8中的终端也可以是支持该终端实现该方法的芯片、芯片系统、或处理器等。图8中示意的方法800包括810部分和820部分。
810部分：终端向网络设备发送第三指示信息，该第三指示信息用于指示下行通信与上行通信的目标优先级信息。相应地，网络设备接收来自终端的第三指示信息。可以理解，终端在发送第三指示信息前，可以确定该目标优先级信息，例如根据终端上下行通信的需求程度、或紧急程度等因素确定该目标优先级信息。可选地，该第三指示信息由RRC信令、MAC控制元素(control element，CE)、或上行控制信息(uplink control information，UCI)承载，其中UCI可以承载在物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)上。该810部分可以理解为方法300中310部分的实施方法2。
820部分：终端根据810部分获得的目标优先级信息，在时间单元上进行下行通信或上行通信。该820部分可以理解为方法300中的320部分。
在810部分的一种可能实施方式中，第三指示信息包括第三取值或第四取值，第三取值与第四取值不同。第三取值用于指示下行通信的优先级高于上行通信，第四取值用于指示上行通信的优先级高于下行通信。该第三取值和第四取值可以是枚举值、整数值或二进制数值，本申请实施例对此不做限定。
通过该实施方法，终端能够依据自身需求选择上下行通信的优先级，能够以分布式的方式优化网络中的上下行传输，从而提升网络资源的使用效率。
在310部分的实施方法3中，终端和网络设备依据对下行通信的预期和/或与上行通信对应的QoS确定该目标优先级信息。
例如，当上行通信对应的时延预算(一种QoS)大于某个门限，或者当上行通信对应的优先级(另一种QoS)低于某个门限时，终端和网络设备确定下行通信的优先级高于上行通信。当上行通信对应的时延预算小于某个门限，或者当上行通信对应的优先级高于某个门限时，终端和网络设备确定上行通信的优先级高于下行通信。
又例如，当终端期望获得来自网络设备的下行信息时(比如终端向网络设备发送了一个请求后等待来自网络设备对该请求的响应)，终端和网络设备确定下行通信的优先级高于上行通信。当终端未期望获得来自网络设备的下行信息时，终端和网络设备确定上 行通信的优先级高于下行通信。
通过上述实施方式能够降低获得目标优先级信息时的信令交互和开销，并且提供了更加灵活与动态的优先级调整方式。
在310部分的实施方法4中，终端依据搜索空间的类型确定该目标优先级信息。这一实施方法主要针对下行通信包括DCI的接收。
例如，当在时间单元上为承载DCI的PDCCH配置的搜索空间为公共搜索空间时，终端可确定在该时间单元上DCI接收的优先级高于上行通信。当在时间单元上为承载DCI的PDCCH配置的搜索空间为特定搜索空间(例如终端特定搜索空间)时，终端可确定在该时间单元上上行通信的优先级高于DCI的接收。
通过上述实施方式能够降低获得目标优先级信息时的信令交互和开销，并且提供了更加灵活与动态的优先级调整方式。

在一种可能的设计中，一种装置1100可包括：处理模块1102和收发模块1101。处理模块1102用于获得下行通信与上行通信之间的目标优先级信息，并根据该目标优先级信息收发模块1101在时间单元上进行下行通信或上行通信。可选地，该上行通信包括上行CG传输和/或随机接入前导的发送。可选地，该下行通信包括DCI的接收和/或下行数据的接收。可选地，上述时间单元的数量为一个或多个，终端可以根据目标优先级信息在该一个或多个时间单元上进行下行通信或上行通信，其中，一个时间单元包括一个或多个时域符号、一个或多个时隙、一个或多个子帧、或者一个或多个无线帧。
通过获取下行通信与上行通信之间的目标优先级信息，并依据该目标优先级信息在 时间单元上执行下行通信或上行通信，从而减少了HD终端或具有HD能力的终端与网络设备的下行通信和自主上行通信之间的冲突，进而提高上下行传输的效率和容量。
在上述装置1100某些可能的实施方式中，在进行下行通信或上行通信的时间单元上配置有下行通信和上行通信。该时间单元上的下行通信和上行通信可以是预定义的，也可以是由网络设备为终端配置的。可选地，在时间单元上配置的下行通信和上行通信可以多于两套。可选地，不同时间单元上下行通信与上行通信间的目标优先级信息可以独立配置或指示。
在上述装置1100某些可能的实施方式中，处理模块1102还用于根据目标优先级信息指示的具体内容控制收发模块1101在时间单元上进行下行通信或上行通信。当该目标优先级信息指示下行通信的优先级高于上行通信的优先级时，则处理模块1102控制收发模块1101在上述时间单元上进行下行通信。当该目标优先级信息指示上行通信的优先级高于下行通信的优先级时，则处理模块1102控制收发模块1101在上述时间单元上进行上行通信。可选地，目标优先级信息指示在该时间单元上下行通信的优先级高于上行通信的优先级，或者，目标优先级信息指示在该时间单元上上行通信的优先级高于下行通信的优先级。
在上述装置1100某些可能的实施方式中，收发模块1101还用于接收来自网络设备的第一指示信息，该第一指示信息用于指示目标优先级信息。可选地，第一指示信息包括第一取值或第二取值，第一取值与第二取值不同。当第一指示信息包括第一取值时，处理模块1102能够根据该第一取值获得的目标优先级信息指示下行通信的优先级高于上行通信的优先级。当第一指示信息包括第二取值时，处理模块1102能够根据该第二取值获得的目标优先级信息指示上行通信的优先级高于下行通信的优先级。该第一取值和第二取值可以是枚举值、整数值或二进制数值。
在上述装置1100某些可能的实施方式中，收发模块1101还用于向网络设备发送第二指示信息，该第二指示信息用于指示下行通信与上行通信之间的候选优先级信息。该候选优先级信息与目标优先级信息可以相同，也可以不同。
在上述装置1100某些可能的实施方式中，收发模块1101还用于向网络设备发送第三指示信息，该第三指示信息用于指示下行通信与上行通信的目标优先级信息。可选地，在收发模块1101发送该第三指示信息之前，处理模块1102还用于确定该目标优先级信息，例如根据上下行通信的需求程度、或紧急程度等因素确定该目标优先级信息。
可选地，第三指示信息包括第三取值或第四取值，第三取值与第四取值不同。第三取值用于指示下行通信的优先级高于上行通信，第四取值用于指示上行通信的优先级高于下行通信。该第三取值和第四取值可以是枚举值、整数值或二进制数值。
在上述装置1100某些可能的实施方式中，处理模块1102还用于依据对下行通信的预期和/或与上行通信对应的QoS确定该目标优先级信息。
例如，当上行通信对应的时延预算(一种QoS)大于某个门限，或者当上行通信对应的优先级(另一种QoS)低于某个门限时，处理模块1102确定下行通信的优先级高于上行通信。当上行通信对应的时延预算小于某个门限，或者当上行通信对应的优先级高于某个门限时，处理模块1102确定上行通信的优先级高于下行通信。
又例如，当终端期望获得来自网络设备的下行信息时，终端的处理模块1102确定下行通信的优先级高于上行通信。当终端未期望获得来自网络设备的下行信息时，终端的处理模块1102确定上行通信的优先级高于下行通信。
在上述装置1100某些可能的实施方式中，处理模块1102还用于依据搜索空间的类型确定该目标优先级信息。
在另一种可能的设计中，一种装置1100可包括收发模块1101。收发模块1101用于接收来自终端的第二指示信息，并向终端发送第一指示信息，第二指示信息用于指示下行通信与上行通信之间的候选优先级信息，第一指示信息用于指示下行通信与上行通信之间的目标优先级信息，目标优先级信息与候选优先级信息指示的内容相同或不同，且目标优先级信息用于指示在时间单元上进行下行通信或上行通信。可选地，该上行通信包括上行CG传输和/或随机接入前导的发送，上行CG传输例如可以承载在PUSCH上，随机接入前导例如可以承载在PRACH上。可选地，该下行通信包括DCI的接收和/或下行数据的接收，DCI例如可以承载在PDCCH上，下行数据例如可以承载在PDSCH上。可选地，上述时间单元的数量为一个或多个，其中，一个时间单元包括一个或多个时域符号、一个或多个时隙、一个或多个子帧、或者一个或多个无线帧。可选地，第一指示信息包括第一取值或第二取值，第一取值用于指示下行通信的优先级高于上行通信的优先级，第二取值用于指示上行通信的优先级高于下行通信的优先级。可选地，上述时间单元上配置有下行通信和上行通信。
通过上述装置，终端能够向网络设备请求下行通信与上行通信的目标优先级信息，由于终端相比网络设备对于其自主上行通信的需求有更多的了解，因此由终端先向网络设备建议终端上下行通信的优先级，再由网络设备参考终端的建议，做出上下行通信的优先级的决策，能够优化网络中的上下行传输，从而提升网络资源的使用效率。
