Description

一种通信方法、装置、芯片及模组设备 技术领域
本申请涉及通信领域，尤其涉及一种通信方法、装置、芯片及模组设备。
背景技术
目前，为了节省能耗，基站可以配置周期性发送信号或者信道。如基站可以周期性地向终端设备发送同步信号块(synchronization signal and PBCH block，SSB)、信道状态信息参考信号(channel state information-reference signal，CSI-RS)、物理下行控制信道(physical downlink control channel，PDCCH)、半持续-物理下行共享信道(semi-persistent-physical downlink share channel，SPS-PDSCH)等。一般来说，基站可以通过配置连接态非连续接收(connected-mode discontinuous reception，C-DRX)实现周期性发送信号或者信道。换句话来说，当终端设备被配置连接态非连续接收时，终端设备仅在激活时间(active time)内接收基站发送的同步信号块、信道状态信息参考信号、物理下行控制信道、半持续-物理下行共享信道等。这意味着终端设备在激活时间内需要进行监听，进而可以接收基站发送的同步信号块、信道状态信息参考信号、物理下行控制信道、半持续-物理下行共享信道等。
可以理解的，因为数据包的到达具有随机性，所以可能存在基站在激活时间内没有数据包要发送给终端设备。在这种情况下，终端设备仍在激活时间内监听信号或信道，反而会增加能耗。
发明内容
本申请提供一种通信方法、装置、芯片及模组设备，可以节省能耗。
第一方面，提供一种通信方法，该方法包括：根据指示信息，确定在第一时间间隔内处于第一状态。
可以看出，上述技术方案中，实现了网络设备在激活时间内没有数据包要发送给终端设备时，通过指示信息可以动态地使得终端设备在第一时间间隔处于第一状态，即在第一时间间隔内不进行信号或信道的监听，节省了能耗。
可选的，结合第一方面，指示信息由下行控制信息(downlink control information，DCI)格式(format)2_6或第一下行控制信息格式携带。
可以看出，上述技术方案中，一可能的实施方式中，重用下行控制信息格式2_6，减小了信令开销。并且终端设备为了获得自身的节能增益需要接收下行控制信息格式2_6。因为下行控制信息格式2_6可以携带指示信息，所以终端设备可以获取到该指示信息，对终端设备来说没有过多额外的操作，降低了终端设备复杂度，节省了终端设备的能耗。另一可能的实施方式中，可以使用一个不同于下行控制信息格式2_6的新的下行控制信息格式(即第一下行控制信息格式)，实现了与下行控制信息格式2_6解耦。网络设备既可以使用第一下行控制信息格式实现节能，又能使用下行控制信息格式2_6实现节能，提高系统灵活性。
可选的，结合第一方面，指示信息由下行控制信息格式2_6携带，第一时间间隔为持 续时间定时器的打开时间。
可以看出，上述技术方案中，可以使得终端设备在持续时间定时器的打开时间内处于第一状态，即在持续时间定时器的打开时间内不进行信号或信道的监听，节省了能耗。
可选的，结合第一方面，指示信息由第一下行控制信息格式携带，第一时间间隔为预设的持续时间；或，第一时间间隔为配置的持续时间；或，第一时间间隔为预设定时器的打开时间；或，第一时间间隔为预设定时器的参数指示的持续时间。
可以看出，上述技术方案中，与持续时间定时器的打开时间解耦，提高系统灵活性。同时，通过预设的持续时间或预设定时器的打开时间或预设定时器的参数指示的持续时间，可以减少信令的开销。另外，通过配置一个持续时间，可以使得该持续时间为满足当前业务需求的时间，提高了系统灵活性。
可选的，结合第一方面，第一状态的开始时间为第一结束符号后的第M个时隙，M为大于或等于1的整数，第一结束符号为物理下行控制信道(physical downlink control channel，PDCCH)的最后一个符号；或，第一状态的开始时间为第二结束符号后的第N个时隙，N为大于或等于1的整数，第二结束符号为物理下行控制信道的最后一个符号后第K个符号，K为大于或等于1的整数；其中，物理下行控制信道承载第一下行控制信息格式。
可以看出，上述技术方案中，因为第一状态的开始时间为第一结束符号后的第M个时隙或第二结束符号后的第N个时隙，所以终端设备可以通过物理下行控制信道获知同步信号块、信道状态信息参考信号、半持续-物理下行共享信道没有被发送后可以取消同步信号块、信道状态信息参考信号、半持续-物理下行共享信道等的接收，节省了能耗。其次，还可以看出第一状态的开始时间不是终端设备接收到物理下行控制信道的时间，这给终端设备预留了更多时间来接收物理下行控制信道，也使得网络设备可以有更多时间来准备物理下行控制信道的发送。
可选的，结合第一方面，获取指示信息，包括：在持续时间定时器的打开时间内，监听第一下行控制信息格式。
可以看出，上述技术方案中，终端设备在持续时间定时器的打开时间内，监听第一下行控制信息格式，使得终端设备可以根据指示信息，确定在第一时间间隔内处于第一状态，这表明终端设备已获知网络设备在激活时间内没有数据包要发送给终端设备，终端设备无需在第一时间间隔内监听信道状态信息参考信号、同步信号块、跟踪参考信号或半持续-物理下行共享信道等，节省了能耗。
可选的，结合第一方面，处于第一状态的终端设备在一个或多个服务小区上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道；或，处于第一状态的终端设备在一个或多个服务小区组上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道。
可以看出，上述技术方案中，因为处于第一状态的终端设备在一个或多个服务小区上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道；或，处于第一状态的终端设备在一个或多个服务小区组上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道，所以可以节省终端设备的能耗。
可选的，结合第一方面，指示信息为一个或多个比特，一个或多个比特对应的任意一 个状态由高层信令中的字段确定。
可以看出，上述技术方案中，一个或多个比特对应的任意一个状态由高层信令中的字段确定，这意味着是否进入第一状态都可以由网络设备通过高层参数配置，如不接收或接收同步信号块、信道状态信息参考信号、半持续-物理下行共享信道中的一个或多个可以由网络设备组合出不同状态，提高了灵活性。
可选的，结合第一方面，指示信息为一个或多个比特，一个或多个比特对应的第一状态用于指示终端设备不进入第一状态，一个或多个比特对应的第二状态由高层信令中的字段确定。
可以看出，上述技术方案中，固定1个状态为不进入第一状态，其他的状态可以由网络设备通过高层参数配置。例如，不接收同步信号块、信道状态信息参考信号、半持续-物理下行共享信道等可以由网络设备组合出1个状态，无需3个状态分别指示不接收同步信号块、信道状态信息参考信号、半持续-物理下行共享信道，既减少了信令两个开销，又提高了灵活性。
可选的，结合第一方面，指示信息为多个比特，多个比特对应一个比特位图，比特位图中的每个比特对应一种信号或信道。
可选的，结合第一方面，指示信息为1比特、2比特或3比特。
第二方面，提供一种通信方法，该方法包括：生成指示信息，指示信息用于指示终端设备在第一时间间隔内处于第一状态；发送指示信息。
可选的，结合第二方面，指示信息由下行控制信息格式2_6或第一下行控制信息格式携带。

一、终端设备
终端设备包括向用户提供语音和/或数据连通性的设备，例如终端设备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(VR)终端设备、增强现实(AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴终端设备等等。本申请的实施例对应用场景不做限定。终端设备有时也可以称为终端、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、UE代理或UE装置等。终端设备也可以是固定的或者移动的。本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统或可实现终端设备功能的组合器件、部件，该装置可以被安装 在终端设备中。
二、网络设备
网络设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、第五代(5th generation，5G)移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。网络设备也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。这里的CU完成基站的无线资源控制协议和分组数据汇聚层协议(packet data convergence protocol，PDCP)的功能，还可以完成业务数据适配协议(service data adaptation protocol，SDAP)的功能；DU完成基站的无线链路控制层和媒体接入控制(medium access control，MAC)层的功能，还可以完成部分物理层或全部物理层的功能。有关上述各个协议层的具体描述，可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)的相关技术规范。网络设备可以是宏基站，也可以是微基站或室内站，还可以是中继节点或施主节点等。本申请实施例中，用于实现网络设备功能的装置可以是网络设备本身，也可以是能够支持网络设备实现该功能的装置，例如芯片系统或可实现网络设备功能的组合器件、部件，该装置可以被安装在网络设备中。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
为了便于理解本申请实施例提供的方案，下面先对本方案涉及到的名词或相关技术进行介绍，后续描述中不再重复说明。
一、持续时间定时器(drx-on duration timer)
持续时间定时器引入的目的为了控制终端设备是否接收物理下行控制信道。持续时间定时器的打开时间属于激活时间。激活时间为一些定时器(timer)运行时的时间间隔，如持续时间定时器、非激活定时器(inactivity timer)等。终端设备仅在激活时间内监听物理下行控制信道。
在本申请中，打开时间又可以理解为激活时间、唤醒时间、持续时间等，在此不做限定。
一般来说，持续时间定时器的打开时间是一个较短的时间，如8毫秒或10毫秒等。
二、下行控制信息格式2_6
本申请中，下行控制信息格式2_6和持续时间定时器是关联的，且具有一定时间关联关系。如下行控制信息格式2_6的监听窗口和持续时间定时器的开始时间有一个可配置的时间偏移量。
三、同步信号块
同步信号块可以看作是扫波束(beam sweeping)过程中一个波束的资源。多个同步信号块组成一个同步信号突发(SS-burst)。同步信号突发可以看作是包含了多个波束的一块资源。多个同步信号突发组成一个同步信号突发集合(SS-burst-set)。同步信号块在不同波束上重复发送，是一个扫波束的过程，通过扫波束的训练，终端设备可以感知在哪个波束上收到的信号最强。
其中，同步信号块可用于波束管理(beam management)，时频跟踪(time/frequency tracking)，移动性管理(mobility management)、无线链路监测(radio link monitoring，RLM)或波束失败检测(beam failure detection，BFD)等。
四、半持续-物理下行共享信道
SPS-PDSCH可以看作是一种半静态调度的PDSCH。终端设备需要在一段时间内周期性的接收PDSCH。
五、搜索空间(search space)
搜索空间可以包括物理下行控制信道的监测时机、搜索空间类型、聚合等级等。
六、信道状态信息参考信号
信道状态信息参考信号可用于测量信道状态信息(channel state information，CSI)，波束管理，时频跟踪，移动性管理、无线链路监测或波束失败检测等。用于信道状态信息测量的信道状态信息参考信号可以称为CSI-RS for CSI。用于波束管理的信道状态信息参考信号可以称为CSI-RS for beam management。用于时频跟踪的信道状态信息参考信号可以称为跟踪参考信号(tracking reference signal，TRS)。用于移动性管理的信道状态信息参考信号可以称为CSI-RS for mobility。用于无线链路监测的信道状态信息参考信号可以称为CSI-RS for RLM。用于波束失败检测的信道状态信息参考信号可以称为CSI-RS for BFD。
其中，跟踪参考信号可以由一个非零功率信道状态信息参考信号资源集参数(NZP-CSI-RS-resource set)配置，一个非零功率信道状态信息参考信号资源集参数可以包含2个连续时隙内的4个非零功率信道状态信息参考信号资源(non zero power CSI-RS resource，简称NZP CSI-RS resource)，并且每个时隙内有两个非零功率信道状态信息参考信号资源。跟踪参考信号可以是周期的，也可以是非周期的。当跟踪参考信号是周期的时候，非零功率信道状态信息参考信号资源集参数内的信道状态信息参考信号资源具有相同的周期、带宽和子载波位置。当跟踪参考信号是非周期的时候，周期的信道状态信息参考信号资源在一个非零功率信道状态信息参考信号资源集参数内，非周期的信道状态信息参考信号资源在另一个非零功率信道状态信息参考信号资源集参数内，并且周期的信道状态信息参考信号资源和非周期的信道状态信息参考信号资源具有相同的带宽(相同资源块位置)，并且非周期的信道状态信息参考信号资源与周期的信道状态信息参考信号资源是准共址类型A(quasi co-location type-A，QCL-Type-A)和准共址类型D的。
因为数据包的到达具有随机性，所以可能存在基站在激活时间内没有数据包要发送给终端设备。在这种情况下，终端设备仍在激活时间内监听信号或信道，反而会增加能耗。为了解决该问题，可以参见图2，图2为本申请实施例提供的一种通信方法的流程示意图。如图2所示，该通信方法包括如下步骤201～步骤203。图2所示的方法执行主体可以为终端设备和网络设备。或者，图2所示的方法执行主体可以为终端设备中的芯片和网络设备中的芯片。图2以终端设备和网络设备为方法的执行主体为例进行说明。
可选的，201、网络设备生成指示信息。
可选的，指示信息可以用于指示以下至少一项：终端设备在第一时间间隔内处于第一 状态、网络设备在第一时间间隔内进入第一状态。第一状态例如为网络设备的进入睡眠的状态。本申请中，第一状态也可以称为睡眠状态、短暂睡眠状态或节能状态。
在第一种可能的实施方式中，指示信息由下行控制信息格式2_6携带。可选的，终端设备在第一时间间隔内处于第一状态或网络设备在第一时间间隔内进入第一状态，可以理解为以下至少一项：终端设备不打开持续时间定时器、终端设备在持续时间定时器的打开时间内不接收物理下行控制信道、终端设备在持续时间定时器的打开时间内不接收SSB、CSI-RS和SPS-PDSCH中的一个或多个。
需要说明的，在本申请中，下行控制信息格式2_6和持续时间定时器有关联，且具有一定时间关联关系，如下行控制信息格式2_6的监听时机的开始时间点和持续时间定时器的开始时间有一个可配置的时间偏移量。一般来说，终端设备需要在开始时间点后的第一个完整的持续时间(搜索空间参数配置)内监听下行控制信息格式2_6。该开始时间点在持续时间定时器的开始时间前，该开始时间点与持续时间定时器的开始时间之间的差值为该时间偏移量。
在一可能的实施方式中，为了保证同步信号块、信道状态信息参考信号或半持续-物理下行共享信道的发送时间，网络设备可以减小同步信号块、信道状态信息参考信号或半持续-物理下行共享信道的周期(密集的同步信号块、信道状态信息参考信号或半持续-物理下行共享信道)，这样可以既保证同步信号块、信道状态信息参考信号或半持续-物理下行共享信道的发送时机不会减少，又可以机会性地(动态地)增加网络设备进入第一状态的时间，达到节能的目的。
其中，在指示信息由下行控制信息格式2_6携带的情况下，该指示信息可以为唤醒指示(wake-up indication)。
可选的，在指示信息由下行控制信息格式2_6携带的情况下，第一时间间隔为持续时间定时器的打开时间。
在第二种可能的实施方式中，指示信息可以由第一下行控制信息格式携带。应理解的，下行控制信息格式2_6和第一下行控制信息格式不同。示例性的，第一下行控制信息格式是新定义的下行控制信息格式。
可选的，第一下行控制信息格式可以被网络设备配置在一个搜索空间内。该搜索空间的聚合等级可以小于或等于预设聚合等级。该搜索空间的监听时机可以比下行控制信息格式2_6更密集，这可以使得发送第一下行控制信息格式的网络设备可以快速且频繁地进入第一状态。
需要说明的，第一下行控制信息格式对应Type3-物理下行控制信道搜索空间集(search space set)。Type3-物理下行控制信道搜索空间集是一种组公共(group common，GC)物理下行控制信道，可以配置给一组终端设备。该一组终端设备监听相同的Type3-物理下行控制信道搜索空间。在指示信息可以由第一下行控制信息格式携带的情况下，第一下行控制信息格式可以通知给网络设备服务的所有终端设备，因此第一下行控制信息格式可以设计和配置为所有终端设备统一监听的下行控制信息格式，这可以使得第一下行控制信息格式的总的比特数较少，如1比特、2比特或3比特，也可以使用较少的聚合等级，降低资源开销。
可选的，在指示信息可以由第一下行控制信息格式携带的情况下，第一时间间隔为预设的持续时间；或，第一时间间隔为配置的持续时间，如网络设备为终端设备配置的持续时间；或，第一时间间隔为配置的定时器，如网络设备为终端设备配置的定时器；或，第一时间间隔为预设定时器的打开时间；或，第一时间间隔为预设定时器的参数指示的持续时间。其中，预设定时器可以不同于持续时间定时器。示例性的，预设定时器可以是新定义的定时器。当然，持续时间也不同于持续时间定时器的打开时间，配置的定时器也可以不同于持续时间定时器。
可以看出，上述技术方案中，与持续时间定时器的打开时间解耦，提高系统灵活性。同时，通过预设的持续时间或预设定时器的打开时间或预设定时器的参数指示的持续时间，可以减少信令的开销。另外，通过配置一个持续时间或定时器，可以使得该持续时间为满足当前业务需求的时间，提高了系统灵活性。
可选的，在指示信息可以由第一下行控制信息格式携带的情况下，第一状态的开始时间为第一结束符号后的第M个时隙，M为大于或等于1的整数，第一结束符号为物理下行控制信道的最后一个符号；或，第一状态的开始时间为第二结束符号后的第N个时隙，N为大于或等于1的整数，第二结束符号为物理下行控制信道的最后一个符号后第K个符号，K为大于或等于1的整数；其中，物理下行控制信道承载第一下行控制信息格式。
可以看出，上述技术方案中，因为第一状态的开始时间为第一结束符号后的第M个时隙或第二结束符号后的第N个时隙，所以终端设备可以通过物理下行控制信道获知同步信号块、信道状态信息参考信号、半持续-物理下行共享信道没有被发送后可以取消同步信号块、信道状态信息参考信号、半持续-物理下行共享信道等的接收，节省了能耗。其次，还可以看出第一状态的开始时间不是终端设备接收到物理下行控制信道的时间，这给终端设备预留了更多时间来接收物理下行控制信道，也使得网络设备可以有更多时间来准备物理下行控制信道的发送。
可选的，202、终端设备获取指示信息。即终端设备接收指示信息。相应的，网络设备发送指示信息。
可选的，在指示信息可以由第一下行控制信息格式携带的情况下，步骤202可以包括：终端设备在持续时间定时器的打开时间内，监听第一下行控制信息格式。
上述第一种可能的实施方式和第二种可能的实施方式可以应用于终端设备，包括指示信息可以由下行控制信息格式2_6和/或第一下行控制信息格式携带。
可以看出，上述技术方案中，终端设备在持续时间定时器的打开时间内，监听第一下行控制信息格式，使得终端设备可以根据指示信息，确定在第一时间间隔内处于第一状态，这表明终端设备已获知网络设备在激活时间内没有数据包要发送给终端设备，终端设备无需在第一时间间隔内监听信道状态信息参考信号、同步信号块、跟踪参考信号或半持续-物理下行共享信道等，节省了能耗。
可选的，对于上述第一种可能的实施方式和第二种可能的实施方式中任意一种实施方式，处于第一状态的终端设备在一个或多个服务小区上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道；或，处于第一状态的终端设备在一个或多个服务小区组上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续- 物理下行共享信道。
需要说明的，本申请中，终端设备可以被配置一个或多个服务小区，多个服务小区可以为至少一个服务小区组。例如，在双连接(dual connectivity，DC)或载波聚合(carrier aggregation，CA)场景中，该一个或多个服务小区可以仅包括终端设备的主小区，也可以仅包括终端设备的辅小区，还可以既终端设备的主小区又包括终端设备的辅小区，在此不做限定。
在一可能的实施方式中，指示信息可以是终端设备的主小区上的信息。这意味着，终端设备接收到主小区上的指示信息时，可以根据该指示信息确定在一个或多个服务小区上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道，或，在一个或多个服务小区组上不接收以下至少一项：同步信号块、信道状态信息参考信号、半持续-物理下行共享信道，减少了信令开销。可以提高灵活性，更可以节省终端设备的能耗。
可选的，对于上述第一种可能的实施方式和第二种可能的实施方式中任意一种实施方式，关于指示信息可以使用以下任意一种方式实现。
方式A、指示信息可以为一个或多个比特，一个或多个比特对应的任意一个状态由高层信令中的字段确定。即一个或多个比特对应的任意一个状态由高层参数确定。需要说明的，高层信令由网络设备发送。

又示例性的，指示信息为2比特，2比特对应的四个状态由高层参数确定。2比特对应的四个状态分别为比特序列00、比特序列01、比特序列10和比特序列11，不同比特序列指示的信息不同。例如，2比特对应一个状态(如比特序列00)例如可以指示终端设备在第一时间间隔内不进入第一状态，2比特对应的另一个状态(如比特序列01)例如可以指示终端设备在第一时间间隔内不接收同步信号块，2比特对应的又一个状态(如比特序列10)例如可以指示终端设备在第一时间间隔内不接收信道状态信息参考信号，2比特对应的又一个状态(如比特序列11)例如可以指示终端设备在第一时间间隔内不接收半持续-物理下行共享信道。上述为一种举例，还有其他的组合方式，在此不加赘述。

方式B、指示信息可以为一个或多个比特，一个或多个比特对应的第一状态用于指示终端设备不进入第一状态，一个或多个比特对应的第二状态由高层信令中的字段确定。即一个或多个比特对应的第二状态由高层参数确定。可选的，第一状态可以为一个或多个比特对应的状态中的一个状态，第二状态可以为一个或多个比特对应的状态中除第一状态的其他状态。
示例性的，指示信息为1比特，第一状态为比特0，第二状态为比特1，反之亦可。如第一状态例如可以指示终端设备在第一时间间隔内不进入第一状态，第二状态例如可以指示终端设备在第一时间间隔内不接收同步信号块、信道状态信息参考信号和半持续-物理下行共享信道中的一个或多个。
又示例性的，指示信息为2比特，2比特对应的四个状态分别为比特序列00、比特序列01、比特序列10和比特序列11，不同比特序列指示的信息不同。例如，第一状态(如比特序列00)例如可以指示终端设备在第一时间间隔内不进入第一状态，第二状态可以包括比特序列01、比特序列10和比特序列11。具体的，比特序列01例如可以指示终端设备在第一时间间隔内不接收同步信号块，比特序列10例如可以指示终端设备在第一时间间隔内不接收信道状态信息参考信号，比特序列11例如可以指示终端设备在第一时间间隔内不接收半持续-物理下行共享信道。上述为一种举例，还有其他的组合方式，在此不加赘述。

203、终端设备根据指示信息，确定在第一时间间隔内处于第一状态。
可以看出，上述技术方案中，实现了网络设备在激活时间内没有数据包要发送给终端设备时，通过指示信息可以动态地使得终端设备在第一时间间隔处于第一状态，即在第一时间间隔内不进行信号或信道的监听，节省了能耗。
