技术领域
本申请涉及移动通信技术领域，尤其涉及一种上行资源确定和配置方法及装置。
背景技术
目前在无线资源控制(radio resource control，RRC)非激活(inactive)态下，支持用户设备(user equipment，UE)的小数据传输(small data transmission，SDT)。具体的，支持基于随机接入(random access，RA)的小数据传输(RA-SDT)和基于配置的上行授权配置(configured grant，CG)类型1(type1)资源的SDT传输(CG-SDT)。
针对CG-SDT，UE可能获得多个CG资源的配置，对于需要进行小数据传输的UE来说，这些资源都是可用的，因此UE会在该多个资源分别对需要发送的数据进行组包，然而UE最终只在其中一个资源进行数据的发送，在该资源以外的其他资源进行组包会导致UE的功耗增加。
发明内容

基于该方法，终端装置可在收到第一上行资源的配置信息后，挂起该配置信息指示的多个上行授权配置，以避免UE在小数据传输过程中在挂起的上行授权配置所对应的资源上进行数据组包，能够降低UE功耗。

具体实施方式
下面将结合附图对本申请作进一步地详细描述。
本申请实施例提供一种上行资源确定和配置方法及装置，用以降低UE在小数据传输中的功耗。其中，本申请所述方法和装置基于同一技术构思，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
在本申请中的描述中，“至少一个(种)”是指一个(种)或者多个(种)，多个(种)是指两个(种)或者两个(种)以上。
为了更加清晰地描述本申请实施例的技术方案，下面结合附图，对本申请实施例提供的通信方法及装置进行详细说明。
图1示出了本申请实施例提供的通信方法可适用的通信系统的架构，所述通信系统的架构中可以包括网络设备和终端设备。
所述网络设备可以为具有无线收发功能的设备或可设置于该网络设备的芯片，该网络设备可以包括但不限于：基站(generation node B，gNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，Wi-Fi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，对此不作限定。
本申请中，网络设备支持与终端装置进行通信。具体的，网络设备可通过通用用户与网络(universal user to network，Uu)接口与UE进行通信，如通过Uu接口配置UE的上行资源。
所述终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(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)中的无线终端、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、智能穿戴设备(智能眼镜、智能手表、智能耳机等)、智慧家庭(smart home)中的无线终端等等，也可以是能够设置于以上设备的芯片或芯片模组(或芯片系统)等。本申请的实施例对应用场景不做限定。本申请中将具有无线收发功能的终端设备及可设置于前述终端设备的芯片统称为终端设备。
本申请中，终端装置支持与网络设备进行通信。具体的，网络设备可通过Uu接口与网络设备进行通信，如通过Uu接口接收来自于网络设备的上行资源的配置信息，和/或，通过Uu接口向网络设备发送上行数据。
需要说明的是，图1所示的通信系统可以但不限于为第四代(4th generation，4G)系统、第五代(5th generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，独立组网(standalone，SA)等。可选的，本申请实施例的方法还适用于未来的各种通信系统，例如第六代(6th generation，6G)系统或者其他通信网络等。
需要说明的是，图1中示出的设备仅仅为示例，通信系统中还可以包含除网络设备和终端设备以外的其他设备，本申请对此不作限定。网络设备和终端设备的个数也仅仅为示例，通信系统中的网络设备和终端设备也可以为多个，本申请对此不作限定。
下面以网络设备是基站且终端装置是UE为例，对本申请实施例提供的方法实施例进行介绍，不应理解为本申请实施例只能以基站和UE实施。
目前的5G NR支持UE在RRC非激活态(以下简称为非激活态)和RRC连接态(以下简称为连接态)下进行数据的传输。小数据传输的过程例如图2所示。本申请中，非激活态也叫RRC_INACTIVE态，是UE保持在连接管理建立(communication management connected，CM-CONNECTED)状态且可以在由接入网设备配置的区域内移动而不需要通知接入网设备的状态，在该状态下UE和接入网设备存储着UE上下文。连接态是指已经建立RRC连接的UE所处的状态。此外，RRC状态还可包括RRC空闲(idle)态(以下简称为空闲态)，是指UE未建立RRC连接的情况下所处的RRC状态。
在如图2所示的步骤0中，处于非激活态或连接态的UE，接收来自于基站的包含挂起配置的RRC释放(release)消息，UE收到该RRC释放消息后，UE进入或保持在非激活态。该RRC释放消息中还可包括UE在非激活态下用于小数据传输的CG配置，其中，CG配置中包含用于上行传输的时域资源分配信息，频域资源分配信息，物理层配置信息，定时器信息，或周期等。基于CG配置，UE可以确定CG传输的时频资源。也即理解为，CG配置是对应于上行授权资源的，可用于上行消息或上行数据的发送。本申请中，对于网络设备通过RRC释放消息等消息配置或预配置的CG配置，可称为配置的CG配置，后续可简称为CG配置，相应地，CG配置对应的资源可称为CG资源。
其中，RRC释放消息中，可包括一个或多个CG资源的配置信息，该CG资源的配置信息可以是CG type1资源的配置信息。通过CG资源的配置信息，可以确定配置的上行授权资源，其中的每个资源都可用于CG-SDT的数据传输。
在接收到该RRC释放消息后，UE处于RRC非激活态。
当UE满足小数据传输条件并基于CG-SDT选择的标准选择了基于CG的小数据传输 时，UE发起CG-SDT过程。
其中，UE满足小数据传输条件，要满足以下条件中的全部条件：
1)待发送的数据的数据量小于配置的阈值。其中，待发送的数据可以是UE缓存的数据。
2)参考信号接收功率(reference signal received power，RSRP)大于配置的RSRP阈值。
3)所有待发送的数据都映射到SDT的无线承载(radio bearer，RB)上，RB例如数据无线承载(data radio bearer，DRB)或信令无线承载(signaling radio bearer，DRB)。后续可将该RB称为SDT RB。其中，SDT的无线承载可以是网络设备配置或预配置或预定义的。
可选的，UE满足小数据传输条件，还包括：小数据传输的CG资源或者RA资源可用。
步骤1，UE在配置的授权上发送第一个上行消息，该上行消息例如是RRC恢复请求(resume request)消息和第一上行数据。
在SDT过程中，UE可根据配置的RSRP阈值进行同步信号和物理广播信道(physical broadcast channel)块(synchronization signal and PBCH block，SSB)的选择。对于CG-SDT，UE选择SS-RSRP高于阈值的SSB，并且UE会选择与该选择的SSB关联的CG资源(或CG配置)，用于上行数据传输，例如，UE可根据该CG资源执行上述步骤1中第一上行消息和第一上行数据的发送。
可选的，步骤1中UE还可发送UE辅助信息，UE辅助信息例如缓冲区状态报告(buffer status report，BSR)和/或释放辅助信息(release assistance information，RAI)。
可选的，如果UE有除了第一个上行数据之外的其他数据要发送，步骤1中UE还可发送UE辅助信息，UE辅助信息例如缓冲区状态报告(buffer status report，BSR)和/或释放辅助信息(release assistance information，RAI)。
步骤2，UE发送第一上行消息后，监听物理下行控制信道(physical downlink control channel，PDCCH)。
基站接收到UE发送的第一上行消息后，发送第一上行消息对应的反馈信息，该反馈信息可以是指示基站对于第一上行数据的接收确认，也可以是响应于第一上行消息的下行消息，其中该下行消息可以是RRC消息和/或下行数据。
步骤3，如果在步骤1中UE还发送UE辅助信息，该辅助信息向基站指示UE有后续数据要传输，则基站可以向UE发送调度信息，用于通过动态调度的方式调度后续传输的授权资源。或者，后续传输也可以通过CG的方式进行传输，即后续传输时仍然从CG资源中确定上行资源。
本申请中，后续传输包括，对上行数据进行分段后，除第一上行数据以外的上行数据。或者，后续传输包括，当前的SDT的数据传输中，有SDT RB对应的新的数据到达，则新到达的数据也可为是后续传输，例如，在UE接收到步骤0之后的下一个RRC释放消息之前，有新的SDT数据需要传输，这些数据也认为是后续传输。或者，后续传输可包括重传数据的传输。
这里的动态调度是指，基站通过下行控制信息(download control information，DCI)等调度信息，调度UE的上行传输授权，该授权可称为动态调度授权(dynamic grant，DG)。
步骤4，如果基站在步骤3中通过动态调度的方式调度了UE的后续传输，则UE根据 步骤3的调度信息进行后续数据的上行传输。此外，如果基站没有进行的动态调度，则UE可基于CG资源进行后续传输，即在CG资源中的下一个可用时机上发送后续传输。
步骤5，如果基站确定UE没有后续传输，则基站可向UE发送RRC释放消息，终止SDT过程。可选的，如果UE未上报辅助信息，或者说，如果基站未接收到UE发送的辅助信息，或者UE上报的辅助信息指示UE没有后续数据传输，则基站可确定没有后续传输。
另外需要注意的是，目前的SDT过程中UE可在一个SDT过程中发多个上行和下行数据，这个过程中UE不需要转换到连接态。
基于图2的小数据传输过程中，如果基站配置了多个用于SDT的CG配置，UE可能会在有待发送的小数据存在的情况下，在选择了执行CG-SDT后，根据全部CG资源对待发送的数据进行组包。如前所述，UE会基于RSRP选择SSB，并基于选择的SSB确定用于上行传输的资源，即从CG资源中确定进行上行传输的资源，也即从多个CG配置中确定用于上行传输的CG配置，最后根据选择的资源进行待发送数据的发送。然而，在选择出用于上行传输的CG资源之前，UE可能针对未选择的CG资源进行组包，由于未选择的CG资源上不会进行数据的发送，换句话说，针对未选择的CG资源上进行组包的数据最终不会被发送，在这些CG资源上进行组包的过程会造成UE功耗的浪费。
为了降低UE在SDT过程中不必要组包带来的功耗，本申请实施例提供一种资源确定和配置方法。该方法可包括图3所示步骤：
S101：基站发送第一上行资源的配置信息，第一上行资源的配置信息包括第一上行资源的多个上行授权配置。本申请中，上行授权配置是指配置的授权配置，即CG配置。
在一种可能的实现方式中，第一上行资源的配置信息还可以只包括一个上行授权配置。其中，第一上行资源如CG资源，上行授权配置如CG配置，可选的，CG配置可以是CG类型1或CG类型2。应理解，如果CG类型是CG类型1，则相应的CG资源为类型1资源，如果CG类型是CG类型2，则相应的CG资源为类型2资源。也就是说，本申请在第一上行资源的配置信息所指示的上行授权配置包括但不限于CG类型是CG类型1的CG配置和CG类型是CG类型2的CG配置。
S101中，第一上行资源可包括多个上行资源，上行资源与上行授权配置之间对应。例如，一个上行资源对应于一个上行授权配置。其中，一个上行授权配置可以是一个CG的配置信息，该配置信息所指示频域，频域，周期等配置，根据一个上行授权配置可以确定一个CG资源，一个CG资源可以对应CG的上行授权的时频资源的多个时机。
可选的，第一上行资源中的资源可与SSB关联，用于UE根据SSB从第一上行资源包括的资源中确定数据的传输资源。具体的，UE基于配置的RSRP阈值，判断UE测量的SS-RSRP与RSRP阈值的关系，UE可选择SS-RSRP大于阈值的SSB，并选择与该SSB关联的CG资源，该CG资源即数据的传输资源。
相应地，UE接收第一上行资源的配置信息。
可选的，该基站在发送第一上行资源的配置信息后，可初始化该多个上行授权配置中的一个或多个。其中，当上层为服务小区配置了CG配置时，UE的媒体接入控制(media access control，MAC)实体将MAC实体的上层提供的上行授权存储为服务小区的配置的上行授权，并初始化或重新初始化配置的上行授权配置，这能够避免UE和基站之间的不对齐。
以上第一上行资源的配置信息可承载于RRC释放消息中，所述承载于是指第一上行资源的配置信息包含在RRC释放消息中。该RRC释放消息可参照图2所示步骤0中的说明。
S102：UE挂起(suspend)多个上行授权配置中的一个或多个。
其中，挂起是指将上行授权配置设置为暂时不使用的状态。进一步可以理解为，UE保持该上行授权配置的配置信息，但该配置是去激活状态。本申请中，UE不会根据挂起的上行授权配置所对应的资源进行数据组包。
根据以上方法，终端装置在收到第一上行资源的配置信息后，挂起该配置信息指示的一个或多个上行授权配置，以避免UE在小数据传输过程中在挂起的上行授权配置所对应的资源上进行数据组包，能够降低UE功耗。
此外，除了挂起多个上行授权配置中的一个或多个，UE还可初始化多个上行授权配置中的一个或多个。其中，UE挂起的上行授权配置和UE初始化或重新初始化的上行授权配置可以相同或不同。初始化能够避免UE和基站之间的不对齐。
下面对S102中UE挂起多个上行授权配置中的一个或多个的方式进行说明。
方式1，UE可以挂起全部上行授权配置，并在进行上行数据传输之前恢复其中的部分上行授权配置，用于根据恢复的上行授权配置对应的资源进行数据传输。本申请中，恢复是指，将被挂起的上行授权配置的状态设置为可用。
具体的，如果上行授权配置携带在RRC释放消息中，则UE可响应于该RRC释放消息，挂起所有的上行授权配置。应理解，所有的上行授权配置还可以替换为任何(any)上行授权配置。之后UE可确定用于数据传输的第一资源，并恢复该第一资源对应的上行授权配置。该第一资源可以是第一上行资源中的一个资源，第一资源可用于UE在CG-SDT过程中发送第一数据。可选的，第一资源也可以是第一上行资源中的多个资源，第一资源可用于UE在CG-SDT过程中发送上行数据。
方式2，UE可以在需要发送上行数据之前，从第一上行资源包括的资源中确定第一资源，并挂起多个上行授权配置中除第一资源对应的上行授权配置以外的上行授权配置。
具体的，UE在接收到第一上行资源的配置信息后，可初始化该配置信息包括的全部上行授权配置。在需要进行小数据传输时，UE可从第一上行资源包括的资源中确定第一资源，并挂起该第一资源对应的上行授权配置以外的其他上行授权配置，从而避免在这些被挂起的上行授权配置所对应的资源进行组包，以节省功耗。UE还可通过第一资源发送第一数据。
应理解，以上方式1和方式2中的第一资源可包括一个或多个可用于进行上行传输的资源。其中，第一资源所传输的第一数据可以是第一无线承载对应的数据，该第一无线承载可以是小数据传输所使用的无线承载，或者说，该第一数据可以是小数据传输中的数据。该第一数据可以是新传或重传数据。其中，新传是指初次传输或第一次传输的数据，重传是指之前发送过，但由于未发送成功而重新传输的数据。
可选的，以上方式1和方式2中的第一资源还可用于发送RRC消息和/或UE辅助信息。RRC消息例如RRC恢复请求消息，UE辅助信息例如是BSR和/或RAI。
以上方式1和方式2中，UE可根据RSRP选择SSB，并恢复选择的SSB所对应的第一资源，其中，UE选择SSB的过程可参照图2所示流程中，UE选择SSB的过程，本申请不予限定。例如，UE可从RSRP不小于RSRP阈值的至少一个SSB中，选择该SSB， 将该SSB关联的资源用于数据传输。
此外，如果UE确定第一资源关联的全部SSB的RSRP均小于RSRP阈值，则UE可发起随机接入过程。可选的，可以通过随机接入过程获得的上行授权进行上行数据的传输。例如，UE在确定第一资源关联的全部SSB的RSRP均小于RSRP阈值的情况下，向基站发送随机接入请求，即可以理解为，UE发起随机接入过程。可选的，该随机接入请求中可携带UE需发送的数据。如果UE有待发送的小数据，且该数据的大小大于随机接入中消息2(即随机接入响应(random access response，RAR))中分配的授权的大小，则UE可以将数据进行分段，在随机接入请求中可携带分段后的第一个数据包。示例性的，该随机接入请求可以是4步随机接入过程中的消息3(Msg3)。
以上方式1和方式2中，在UE确定第一资源以后，如果RSRP发生变化，导致UE的定时提前(timing advance，TA)无效，则UE挂起此前确定的第一资源。其中，TA无效的原因可能是UE确定TA定时器超时，其中，TA定时器用于确定当前TA有效，TA定时器是配置的一个值，如果在TA定时器超时之前，UE没有收到网络的TA命令，则TA定时器会一直运行，直到超时。其中，TA命令用于TA更新及重启定时器，即理解为，UE收到TA命令，则更新TA；如果UE在TA定时器超时之前，收到TA命令，UE重启TA定时器。或者，TA无效的原因可能是UE确定TA的变化(或变化量、变化幅度)超出阈值，其中，TA的变化对应于服务小区的RSRP变化。其中，自上次TA验证以来，服务小区RSRP的增加幅度未超过(或达到)阈值1，该阈值1可以是RSRP增加幅度阈值(例如，rsrp-IncreaseThresh)，并且自上次TA验证以来，服务小区RSRP的减少幅度未超过(或达到)阈值2，该阈值2可以是RSRP减少幅度阈值(例如，rsrp-DecreaseThresh)，则不是TA的变化未超出阈值。
在一种可能的实现方式中，如果UE确定TA无效，则向发起随机接入过程，并重新获得TA。在重新获得TA之后，UE仍可采用此前的CG配置进行小数据传输。
本申请中，还可以由基站向UE指示或者通过预配置方式或由协议定义或由UE实现决定，限定第一资源只能用于新传或是即可用于新传也可用于重传。
其中，UE可以在通过第一资源发送第一数据，并接收到基站针对第一数据的反馈信息。
如果第一资源只能用于新传，则UE可响应于该反馈信息挂起和/或重配置第一资源对应的上行授权配置，该反馈信息可用于确定基站是否成功接收该第一数据。可选的，本申请中，基站可通过第一资源接收来自于UE的第一数据，并在发送第一数据的反馈信息后，初始化第一资源对应的上行授权信息。
如果需要发送后续传输，则可以要UE通过以上方式1或方式2，重新确定用于传输数据的资源，其中，重新确定的资源可以是第一资源，也可以是第一资源以外的其他资源。或者，可由基站动态调度用于后续传输或新传数据的传输的资源，基站动态调度的方式例如可参照图2所示步骤3所示。这里的后续传输包括但不限于传输第一数据的重传数据。其中，如果需要发送后续传输，UE可向基站发送辅助信息，以指示存在后续传输，否则，如果基站未接收到辅助信息，则确定UE不存在后续传输。
如果第一资源即可用于新传也可用于重传，则在发送第一数据后，如果UE还需要发送后续传输或第一数据的重传数据，则UE仍可通过第一资源进行数据的发送，不需要重 新选择资源。
可选的，如果基站决定将UE释放到非激活态，则基站可向UE发送包含挂起配置的RRC释放消息，UE可根据该RRC释放消息，挂起和/或初始化全部(或任何)上行授权配置。可选的，该RRC释放消息也可以重新配置下一个SDT传输的CG配置，如表看重新配置的CG配置。此时UE可保持在RRC非激活态。
另外，如果基站决定将UE释放到空闲态，则基站可向UE发送不包含挂起配置的RRC释放消息，UE接收到该RRC释放消息后，可释放到RRC空闲态。
基于相同的发明构思，本申请实施例还提供一种用于上行资源的确定或配置的装置(以下简称为通信装置)，用于实现以上由终端装置(或UE)和/或网络设备(或基站)实现的功能。该装置可包括图4至图6中任一所示结构。
应理解，该用于上行资源的确定的装置也可称为上行资源确定装置，可以是UE或者UE中的组件。该用于上行资源的配置的装置也可称为上行资源配置装置，可以是网络设备或者网络设备中的组件。
如图4所示，本申请实施例提供的一种通信装置可以包括收发模块420以及处理模块410，以上收发模块420以及处理模块410之间相互耦合。该通信装置可用于执行以上图3中所示的由源发送设备(或源基站)、接收设备(或UE)或目标发送设备(或目标基站)中的任意一个或多个所执行的步骤。具体的，该收发模块420可用于支持通信装置进行通信，收发模块420也可被称为通信单元、通信接口、收发模块或收发单元。收发模块420可具备无线通信功能，例如能够通过无线通信方式与UE进行通信，以及可具备有线通信功能，用于支持通信装置通过有线通信接口进行通信。处理模块410可用于支持该通信装置执行上述方法实施例中所示的由源发送设备、接收设备或目标发送设备中的任意一个或多个所执行的步骤，和上述实施例未示出的一些步骤，执行步骤包括但不限于：生成由收发模块420发送的信息、消息，和/或，对收发模块420接收的信号进行解调解码处理等等。
在通过图4所示结构实现本申请实施例提供的终端装置时，收发模块420可用于执行上述方法实施例中由终端装置执行的接收和/或发送的动作。处理模块410可用于执行上述方法实施例中由终端装置执行的接收和发送以外的动作。例如，收发模块420可执行：第一上行资源的配置信息的接收，第一数据的反馈信息的接收，或随机接入消息的发送等动作。例如，处理模块410可用于执行：上行授权配置中的一个或多个的挂起，响应于释放消息挂起所有的上行授权配置，第一资源对应的上行授权配置的恢复，第一资源的确定，第一资源对应的上行授权配置的挂起，或多个上行授权配置中的第一资源对应的上行授权配置以外的上行授权配置的挂起等动作。
在通过图4所示结构实现本申请实施例提供的网络设备时，收发模块420可用于执行上述方法实施例中由网络设备执行的接收和/或发送的动作。处理模块410可用于执行上述方法实施例中由网络设备执行的接收和发送以外的动作。例如，收发模块420可用于执行：第一上行资源的配置信息的发送，或第一数据的反馈信息的发送等动作。处理模块410可用于执行多个上行授权配置中的一个或多个的初始化，或第一资源对应的上行授权配置的初始化等动作。
图5示出了另一种通信装置的结构示意图，用于执行本申请实施例提供的由终端装置 执行的动作。如图5所示，通信装置可包括处理器和存储器。处理器主要用于对通信协议以及通信数据进行处理，以及对通信装置进行控制，执行软件程序，处理软件程序的数据等。存储器主要用于存储软件程序和数据。
以上通信装置还可包括天线和射频电路，用于通过无线通信方式进行通信，例如，终端装置可通过天线和射频电路向接收设备发送数据，或通过天线和射频电路接收数据。当需要发送数据(或信息、信号)时，通信装置的处理器还可对待发送的数据进行基带处理，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据(或信息、信号)发送到通信装置时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。
在本申请实施例中，可以将具有收发功能的天线和/或射频电路视为通信装置的收发单元。收发单元还可包括通信接口等。收发单元可以是一个功能单元，该功能单元能够实现发送功能和接收功能；或者，收发单元也可以包括两个功能单元，分别为能够实现接收功能的接收单元和能够实现发送功能的发送单元。还可将具有处理功能的处理器视为通信装置的处理单元。如图5所示，通信装置可包括收发单元510和处理单元520。收发单元也可以称为收发器、收发机、收发装置等。处理单元也可以称为处理器，处理单板，处理模块、处理装置等。可选的，可以将收发单元510中用于实现接收功能的器件视为接收单元，将收发单元510中用于实现发送功能的器件视为发送单元，即收发单元510包括接收单元和发送单元。收发单元有时也可以称为收发机、收发器、或收发电路等。接收单元有时也可以称为接收机、接收器、或接收电路等。发送单元有时也可以称为发射机、发射器或者发射电路等。
应理解，收发单元510可与收发模块420对应，或者说，收发模块420可由收发单元510实现。收发单元510用于执行本申请所示实施例中的终端装置的发送操作和接收操作，和/或用于支持本文所描述的技术的其它过程。处理单元520可与处理模块410对应，或者说，处理模块410可由处理单元520实现。处理单元520用于执行本申请所示实施例中终端装置的除了收发操作之外的其他操作，例如用于执行本申请所示实施例中由终端装置所执行的除接收和发送以外的全部操作，和/或用于支持本文所描述的技术的其它过程。
也就是说，以上示例中由处理模块410执行的终端装置动作可由图5所示的处理单元520执行，不再赘述。同理，以上由收发模块420执行的终端装置的动作可由图5所示的收发单元510执行。
为便于说明，图5中仅示出了一个存储器和处理器。在实际的通信装置中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
