下面对本申请所涉及到的名词(或通信术语)进行解释说明。
1、空闲态(idle)
当终端设备处于空闲态时，终端设备未保留无线资源控制(radio resource control，RRC)，上下文(context)。RRC上下文是终端设备与网络设备之间建立通信的参数。RRC上下文可以包括安全上下文、终端设备的能力信息等。同时，终端设备也未与核心网设备建立连接，即核心网设备处于CN-IDLE(核心网空闲态)。终端设备不存在待传送的数据，自身将进入休眠(Sleep)状态，关闭收发单元以降低功耗。处于空闲态的终端设备仅周期性地唤醒以接收寻呼消息。
2、连接态(connected)
当终端设备处于连接态时，终端设备已建立RRC上下文。终端设备与网络设备之间建立通信所需的参数已被通信双方所获取。网络设备为接入的终端设备分配小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。同时，终端设备也与核心网设备建立连接，即核心网设备处于CN_CONNECTED(核心网连接态)。此时，如终端设备正在传送数据，则处于连续接收状态，直至数据传送完成而进入等待状态时，切换为连接态非连续接收(discontinuous reception，DRX)以节省功耗。如果后续还有数据待传送，终端设备则再次返回连续接收状态。此时，由于RRC上下文已建立，UE离开连接态DRX并准备连续接收所需的切换时间相对于从空闲状态切换到连接状态的时间要短得多。
3、去激活态(inactive)
当终端设备处于去激活态时，终端设备和网络设备之间保留了RRC上下文。同时，终端设备也与核心网设备建立连接，即核心网设备处于CN_CONNECTED(核心网连接态)。此时，切换到连接态以进行数据接收的流程是相对快速的，且无须产生额外的核心网信令开销。此外，处于RRC去激活态的终端设备也同样会进入休眠状态。因此，去激活态能够满足降低连接时延、减小信令开销和功耗的需求。
4、带宽部分(bandwidth part，BWP)
BWP可定义为一个载波内连续的多个资源块(resource block，RB)的组合。
BWP主要分为两类：初始(initial)BWP和专用(dedicated)BWP。initial BWP主要用于终端设备接收剩余最小系统信息(remaining minimum system information，RMSI)、按需系统信息(ondemandsysteminformation，OSI)发起随机接入等。当终端设备从空闲态进入到连接态的时，所驻留的小区的BWP称为"initial BWP"，因为终端设备是在该BWP发起初始接入过程。dedicated BWP主要用于数据业务传输，dedicated BWP的带宽一般比initial BWP大。
在新空口(new radio，NR)频分双工(time division depluxing，FDD)系统中，一个终端设备最多可以配置4个上行(down link，DL)BWP和4个下行(up link，UL)BWP。在任意特定时刻，只能有一个激活上行BWP以及激活下行BWP。上下行数据信道、控制信道以及参考信号都不能在超出BWP的范围以外传输。具体的，下行方向：在每个单元载波上，一个终端设备最多可以配置4个BWP，但是某个时刻只有一个处于激活态；激活态BWP表示小区工作带宽之内终端设备所采用的工作带宽，在BWP之外，终端设备不会接收物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，物理下行控制信道(physical downlink control channel，PDCCH)或者信道状态参考信号(channel state information reference signal，CSI-RS)(除非用于移动性无线电资源管理(radio resource management，RRM))。上行方向：在每个单元载波上，一个终端设备最多可以配置4个BWP，但是某个时刻只有一个处于激活态；如果终端设备配置有上行链路(supplementary uplink，SUL)，则终端设备可以在SUL上额 外配置最多4个BWP且同时只能激活一个BWP；终端设备不能在BWP之外传送PUSCH、PUCCH。对于激活的小区，终端设备也不再使用BWP之外传送探测参考信号(sounding reference signal，SRS)。在NR时分双工(time division deplux，TDD)系统中，一个终端设备最多配置4个BWP Pair。BWP Pair是指DL BWP标识(ID)和UL BWP ID相同，并具有相同的中心频率，但是带宽和子载波间隔可以不同。
BWP的配置分为以下三种情况：初始BWP、激活(active)BWP和默认(default)BWP。
其中，初始BWP包括initial DL BWP和initial UL BWP，initial DL BWP和initial UL BWP会在系统消息块(system information block，SIB)1中配置，如果initial BWP未配置，则默认为CORESET0。初始BWP主要用于初始接入过程，如SIB1的接收，随机接入过程当中随机接入响应(random access response，RAR)、Msg4的接收以及前导(preamble)和Msg3的发送等。
激活(active)BWP是用于初始接入完成以后，为终端设备配置的BWP。初始接入完成以后，终端设备会有各种业务需求，所以一般active BWP的带宽比初始BWP要大。
默认(default)BWP用于终端设备长时间没有业务需求的情况下，让终端设备从大带宽的active BWP切换到默认的带宽较小的BWP上，用于降低功耗。
BWP的配置信息包括SCS、循环前缀(cyclic prefix，CP)、频域位置、大小(指示方式为资源标识符(resource indicator value，RIV))、ID、BWP内的PDCCH、BWP内的PDSCH的通用参数和专用参数(generic parameters and dedicate parameters)。
其中，在该BWP内的PDCCH、PDSCH等的SCS和CP都和该BWP相同。BWP的带宽可以是275RB以内的任意值，根据位置和带宽(location and bandwidth)指示一个RIV，然后通过公式计算得到BWP的起始位置和RB数量，起始位置的参考点是Point A。
BWP的切换包括以下四种切换场景：伴随数据调度的下行控制信息(downlink control information，DCI)指示的快速切换；RRC(重)配置和激活辅小区(secondary cell，SCell)时从initial BWP到first active BWP的切换；基于定时(timer)的长时间没有业务调度的切换；终端设备在随机接入过程中，如果active BWP内没有物理随机接入信道(physical random access channel，PRACH)资源，则自动切换到initial BWP。
这四种切换场景，涉及到三种切换方式。其一为DCI_based切换，DCI切换用于在有数据调度时，快速实现BWP的切换。DCI中通过BWP indicator来指示BWP的切换。DCI format 0_1、1_1可以用于DCI切换，但不会只用于DCI切换。如果终端设备收到的DCI中指示的激活BWP与当前的不同，则触发DCI切换。但要注意当终端设备进行DCI BWP切换时，该DCI调度的数据要在新的BWP上面传输，所以当前DCI中information field size未必与新的BWP解释该information field需要的size相同，所以在解释的时候可能需要补零或去掉几比特(bit)。其二为RRC_based切换，RRC BWP切换用于终端设备完成初始接入进入连接态后或RRC重配后或SCell激活后，能让终端设备进入合适的BWP进行业务收发，而不是一直停留在initial BWP上。终端设备在初始接入的过程中，一直使用的是initial BWP，即一般是SIB和随机存取(Random Access，RA)相关的一些操作在initial BWP内完成。其三为Timer_based切换，Timer_based切换用于终端设备在长时间不进行业务收发(意味着终端设备此时可能没什么业务需求)，则让终端设备切换到一个带宽较小的default BWP以达到节能的目的。当前协议中只有下行BWP需要进行timer_based切换，上行不需要，因为一般下行BWP带宽比较大，更加耗电。具体多长时间由带宽部分激活定时(bwp inactivity timer)指示(bwp inactivity timer表示多长时间没有业务)需求，具体的default BWP由默认下行带宽部 分标识(default down link BWP Id)来指示。一旦初始接入完成，进入连接态，则网络设备可以通过第一激活下行带宽部分标识(first active down link BWP Id)以及第一激活上行带宽部分标识(first active up link BWP Id)来激活除initial BWP以外的BWP，通常激活的带宽要比initial BWP大一些。
另外，在随机接入的过程中，如果在active UL BWP上没有PRACH资源，终端设备则自动切换到initial UL BWP，对应的DL BWP也要切换到和UL BWP对应的pair。如果切换到了initial UL BWP，则active DL BWP也切换到initial DL BWP；如果没切换到initial BWP，则active DL BWP的ID要和active UL BWP的ID相同，不同的话就需要切换active DL BWP。
终端设备在随机接入过程中如果收到DCI指示的BWP切换时，是否切换BWP取决于终端设备自己的行为，或切换到新的BWP上重新开始随机接入或忽略切换的指示。
但终端设备在随机接入过程中如果收到了RRC配置或重配指示的BWP切换，终端设备则需要停止目前的随机接入过程，进行BWP的切换。
5、半持续调度(semi persistent scheduling，SPS)
SPS又称为半静态调度。当网络设备在某个发送时间间隔(transmission time interval，TTI)采用SPS C-RNTI加扰的PDCCH指定终端设备所使用的无线资源(在本申请中，称为SPS资源)时，每过一个周期，终端设备可以使用该SPS资源来传输数据。
SPS调度和释放配置可通过RRC重配置消息进行查看，主要的配置参数包括：配置调度RNTI(configured scheduling-RNTI，CS-RNTI)：用于激活、去激活和重传；周期(periodicity)：SPS资源的使用周期；HARQ进程数(nrof HARQ-Processes)：针对SPS配置的HARQ进程数。

目前，在窄带物联网(narrow band internet of things，NB-IoT)场景下，处于空闲态的终端设备可以通过数据提前传输(earlydatatransmission，EDT)技术或上行预配置资源(pre-configuration uplink resource，PUR)技术实现与网络设备之间的数据传输。具体的，结合表1，可以看出，在利用EDT技术或PUR技术实现与网络设备之间的数据传输时，只能实现数据的单次传输，无法实现数据的连续性或周期性传输。
