本申请主张在2020年10月22日在中国提交的中国专利申请号No.202011141197.2的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种数据传输方法、装置、终端、网络侧设备及存储介质。
背景技术
高效小数据传输的特点是对于非连接态(例如，空闲(IDLE)态和非激活(INACTIVE)态)的终端(User Equipment,UE)，避免因此引起的无线资源控制(Radio Resource Control,RRC)状态转换和RRC连接建立过程的造成过多信令开销，通过极简单的信令过程即完成小数据传输的目的。
小数据传输方案的特点是UE当前数据无线承载(Data Radio Bearer,DRB)都是处于挂起的状态，而不是释放的状态。因而，UE在发送恢复请求(Resume Request)消息前可以先恢复DRB，然后再用RRC信令来捎带小数据，这时和连接(CONNECTED)态UE一样可以在DRB上传输数据。从而避免进行状态转换，以较小的信令开销达到高效小数据传输的目的。
针对INACTIVE态的UE进行小数据传输的场景，网络侧需要给UE配置基于配置授权(configured grant)的小数据传输资源，但是，目前还没有涉及新空口(New Radio,NR)UE的配置资源，以及如何利用配置资源进行上行数据传输的相关方案，小数据传输效率低，因此，如何进行基于配置资源的数据传输，以提高小数据传输的效率是一个迫切需要解决的问题。

具体来说，UE接收网络侧配置专属上行资源(简称“上行传输资源”)发送上行数据。本申请实施例以第一参考信号为下行信号，以第二参考信号为上行信号为例进行说明。
例如，网络设备侧在RRC释放(Release)消息中给INACTIVE状态UE携带配置授权(Configured grant)的配置信息，该配置信息包括了INACTIVE UE发送上行数据专属的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)资源。

5.第一参考信号和上行传输时机的关联配置信息。
第一参考信号和上行传输时机的关联配置信息指示多少个第一参考信号关联到一个上行传输时机(例如，1/8表示1个SSB映射到8个上行传输时机，8表示8个SSB映射到1个上行传输时机，从而使得SSB和上行传输时机具有关联关系)。
6.第一参考信号和第二参考信号的关联配置信息。
可选地，第一参考信号和第二参考信号的关联配置信息可以包括以下至少一项：

(4)第二参考信号的码分复用组(CDM group)信息(例如，λ＝0)。

例如，第一参考信号和第二参考信号的关联配置信息中SSB-index为1，ScramblingID0＝0,ScramblingID1＝1，λ＝0，DMRS port index＝0，则表示SSB1和根据ScramblingID0＝0,ScramblingID1＝1，λ＝0，DMRS port index＝0构成的DMRS信号存在关联关联。又例如，第一参考信号和第二参考信号的关联配置信息中SSB-index为2，ScramblingID0＝11,ScramblingID1＝20，λ＝0，则表示SSB2和根据ScramblingID0＝11,ScramblingID1＝20，λ＝0构成的DMRS信号存在关联关联，在此不一一举例。
可选地，该第一参考信号至少可以是SSB或者CSI-RS中的一种，第二参考信号可以是上行解调参考信号(Demodulation Reference Signal,DMRS)。

图3为本申请实施例提供的上行传输时机的次序规则示意图。假设配置中上行传输时机在一个时刻上频分复用的个数是2，一上行传输时机分配数目是2，时隙分配数目是2，则上行传输时机的编号如图3所示。
2.第一参考信号和上行传输时机的关联。
例如，UE先验证所有配置的上行传输机会是否有效，然后对于每个CG配置，根据一个CG周期内所有有效的上行传输时机和配置SSB的个数用于确定映射回合数(mapping cycle)，进行SSB和上行传输机会的映射。假设网络配置了SSB1/2/3/4，一个CG周期内有上行传输时机#1/2/3/4/5/6/7/8都是有效的，则此时进行两轮映射(即，floor(8/4)＝2)，最后将SSB1关联到上行传输时机#1和5，SSB2关联到上行传输时机#2和6，如此类推。
3.用于新传的混合自动重传请求HARQ进程信息。
(1)协议预定义或网络设备侧配置UE可用的HARQ进程信息。
例如，对于一个CG配置，在一个CG周期内，对于任一个上行传输时机，其相应的HARQ进程被协议预定义或网络侧配置为0。同样地，在其后的CG周期内，对于任一个上行传输时机，其相应的HARQ进程被协议预定义或网络侧配置为0。
(2)协议预定义或网络侧配置UE可用的HARQ进程信息。
例如，对于一个CG configuration，在第一个周期内，对于任一个上行传输时机，其相应的HARQ进程约定为0；在第二个周期内，对于任一个CG，UE可用的HARQ进程约定为1，如此类推。或者理解为：一个CG周期内，任一个上行传输时机对应的HARQ进程都是编号为最小的上行传输时机对应的HARQ进程。其中，如何确定编号为最小的上行传输时机对应的HARQ进程在此不限制。
4.第一参考信号和路径损耗参考信号的关联。
进行基于配置资源的数据传输时，PUSCH对应的路径损耗参考信号(pathloss RS)是由UE自助选择的。
可选地，PUSCH的pathloss RS是当前服务小区当前激活下行带宽部分(DL BWP)(例如，初始DL BWP)上和此次PUSCH传输关联的第一参考信号。
例如，网络配置了SSB1/2/3/4，UE触发了基于配置资源的数据传输过程，那么UE根据用于第一参考信号选择的测量质量门限，选择了SSB2(也即是SSB2为目标下行信号)，并且根据SSB2关联的上行传输时机和第二参考信号进行PUSCH发送，那么UE就将SSB2 作为PUSCH的pathloss RS，从而通过使用SSB2计算出下行路径损耗估计
可选地，在使用上行传输资源进行数据传输之前，包括：
步骤0：如果在一个CG周期内所有上行传输时机上基于配置资源的数据传输过程都没有被触发，则执行如下步骤：
可选地，第一计数器加1。
该第一计数器用于统计数据传输跳过次数，如果第一计数器的值＝最大上行跳过次数，即第一计数器的值大于最大上行跳过次数时，则终止(结束)基于配置资源的数据传输过程，释放上行传输资源，丢弃配置信息。
可选地，如果在N个连续的CG周期内所有上行传输时机上基于配置资源的数据传输过程都没有被触发，则结束基于配置资源的数据传输过程，释放上行传输资源，丢弃配置信息；门限值N可以由网络侧设备(NW)配置或协议约定或者预定义。
可选地，该过程可以是按照每一配置授权配置(per CG configuration)中的每一配置授权周期(per CG periodicity)进行的。
例如，假设网络侧配置了两个CG configuration，则UE需要对CG configuraton1/2对应的每个CG周期进行上述过程。
步骤1：基于配置资源的数据传输过程被触发后，可以执行以下至少一项：
1.RRC层指示MAC层基于配置资源的数据传输过程被触发。
2.MAC层被RRC层指示基于配置资源的数据传输过程被触发后,保存专属上行资源以及对应的HARQ信息。
可选地，上行资源也可以理解成上行授权UL grant，或者配置授权CG。
3.MAC层初始化/重新初始化专属上行资源。
4.如果在一个CG周期内所有上行传输时机上都没有生成对应MAC PDU(可以理解成没有进行PUSCH发送)，MAC层向高层(RRC层)发送一个上行跳过指示，高层对第一计数器加1(该第一计数器用于统计数据传输跳过次数)。
如果第一计数器的值＝最大上行跳过次数，即第一计数器的值大于最大上行跳过次数时，则终端行为包括以下至少一项：
(1)结束基于配置资源的数据传输过程。
(2)RRC向MAC层指示结束基于配置资源的数据传输过程。
(3)MAC清除步骤1保存专属上行资源以及对应的HARQ信息。
(4)RRC丢弃步骤0的所有保存的配置信息。
步骤2：UE通过专属上行资源发送上行数据前先进行初始化。
如果网络侧配置了高优先级power ramping step参数，而且如果高层提供了接入ID1或者2，而且如果网络侧指示UE使用高优先级power ramping step参数，则UE设置高优先级power ramping step参数。
否则，UE设置低优先级power ramping step参数。
可选地，该过程是per CG configuration进行的。
例如，假设网络侧配置了两个CG configuration，则UE需要对CG configuraton1/2对进行上述过程。
步骤3：UE通过专属上行资源发送上行数据前先进行发送资源的选择。
1.根据用于第一参考信号选择的测量门限，UE先选择第一参考信号用于基于配置资源的数据传输过程。
例如，假设网络侧配置SSB1/2/3/4，根据网络配置的质量门限值(例如，门限值为-80dBm)进行第一参考信号的选择。UE根据最新测量到的SSB1/2/3/4的L1-RSRP，假设只有SSB3的L1-RSRP(例如：-70dBm)高于门限值，则UE选择SSB3。
2.根据选择的第一参考信号和/或第一参考信号和第二参考信号的关联配置信息，产生(generate)第二参考信号。
例如，第一参考信号和第二参考信号的关联配置信息配置SSB-index为2，ScramblingID0＝11,ScramblingID1＝20，λ＝0根据选择的第一参考信号是SSB2，则根据ScramblingID0＝11,ScramblingID1＝20，λ＝0构成第二参考信号(DMRS)。
3.根据选择的第一参考信号，确定一个最近可用的上行传输时机(上行传输时机和选择的第一参考信号存在关联关系)。
4.可选地，UE从根据选择的第一参考信号所关联的连续的上行传输时机中随机等概率地选择一个。
例如，图4为本申请实施例提供的上行传输时机和第一参考信号的关联关系示意图之一，如图4所示，假设网络侧配置SSB1/2，根据网络配置的质量门限值(例如，门限值为-80dBm)进行第一参考信号的选择。UE根据最新测量到的SSB1/2的L1-RSRP，假设只有SSB2的L1-RSRP(例如：-70dBm)高于门限值，则UE选择SSB2，然后从SSB2关联的两个上行传输时机(#3/4)中随机等概率地选择一个(例如#3)，可以理解上行传输时机(#3/4)是对应SSB2最近可用的上行传输时机。
可选地，确定一个最近可用的上行传输时机还可以根据根据选择的第一参考信号和上行传输时机掩码(mask)信息。
例如，图5为本申请实施例提供的上行传输时机和第一参考信号的关联关系示意图之二，如图5所示，假设网络侧配置SSB1/2，根据网络配置的质量门限值(例如，门限值为-80dBm)进行第一参考信号的选择。UE根据最新测量到的SSB1/2的L1-RSRP，假设只有SSB2的L1-RSRP例如：-70dBm)高于门限值，则UE选择SSB2，假设上行传输时机mask信息指示的值为1(例如：1即是指示UE使用选择的SSB所关联的上行传输时机中第一个)，然后UE则选择最近可用的SSB2#0，由例如假设上行传输时机mask信息指示的值为0(例如：0即是指示UE使用选择的SSB所关联的上行传输时机都可使用)，则UE从SSB2关联的最近可用的两个上行传输时机(SSB2#0/1)中随机等概率地选择一个(例如#0)。最终UE实现了根据选择的SSB(例如：SSB2)，在选择的上行传输时机上(例如#0)，发送PUSCH，所述PUSCH的上行DMRS即是根据选择的SSB产生(generate)第二参考信号(根据ScramblingID0＝11,ScramblingID1＝20，λ＝0构成的上行DMRS)。
5.根据选择上行传输时机，确定上行授权(UL grant)和对应的HARQ信息。例如，HARQ进程识别码(HARQ process ID)，新数据指示比特(new data indicator bit，NDI bit)，传输块大小(Transport Block Size,TBS)。
6.将UL grant以及对应的HARQ信息递交给HARQ实体。
可选地，只有在UL grant对应HARQ process ID对应的CG response timer和/或CG timer没有运行时，才将UL grant以及对应的HARQ信息递交给HARQ实体(可以理解成在CG response timer运行期间，其相应的HARQ process不能用于进行新传或者重传)。
可选地，只有在UL grant对应HARQ process ID对应的CG timer没有运行时，才将UL grant以及对应的NDI bit进行反转(toggle)(可以理解成在CG timer运行期间，其相应的HARQ process不能用于进行新传)。
7.可选地，HARQ实体按照预定义规则，进行上行跳过(UL skipping)，不产生MAC PDU，并向RRC层上报一个上行跳过指示。
8.可选地，该过程可以是per CG configuration per CG周期进行的。
例如，假设网络侧配置了两个CG configuration，则UE需要对CG configuraton1/2对应的每个CG周期进行上述过程。
步骤4.1：如果获得了一个MAC PDU，则指示对应的HARQ进程进行数据发送。
步骤4.2：UE通过和专属上行资源发送上行数据时：
1.根据第二计数器，暂停功率提升计数器(suspending poewer ramping counter)的指示，先听后传(listen before talk，LBT)失败指示，上行跳过指示，此次发送所选择的第一参考信号，对第三计数器加1。
例如，如果第二计数器的值大于1，而且没有从物理层收到一个suspending poewer ramping counter的指示，而且没有从物理层收到一个LBT失败指示，而且没有MAC层没有产生一个上行跳过指示，而且，此次发送所选择的第一参考信号没有发生变化(理解为此次发送所选择的第一参考信号和上次发送选择的第一参考信号是同一个)，则对第三计数器加1。该第三计数器用于计算累计power ramping总和。
2.MAC层将累计power ramping总和(例如，(第三计数器的值-1)*设置的power ramping step参数)，以及期望接收功率指示给物理层。
3.物理层可以根据累计power ramping总和，下行路径损耗估计，期望接收功率，确定数据传输的上行发送功率。
4.可选地，该过程是per CG configuration per CG周期进行的。
例如，假设网络侧配置了两个CG configuration，则UE需要对CG configuraton1/2对应的每个CG周期进行上述过程。
步骤5：UE通过专属上行资源发送上行数据后接收响应：
1.当一个MAC PDU在上行传输时机传输(例如：配置授权对应的PUSCH(CG-PUSCH))发送后，不管有没有潜在的测量间隔(measurement gap)，UE在CG-PUSCH后第一个PDCCH occasion启动CG response timer，在该timer运行期间，UE监听某一RNTI加扰的PDCCH。
可选地，UE启动CG timer(其启动时刻和CG response timer一致)。
2.UE假设步骤3中选择的第一参考信号(可以理解成和发送CG-PUSCH存在关联关系的第一参考信号)和DM-RS天线端口(可以理解成PDCCH的DMRS)具有相同的准正交特性(quasi co-location properties)。
3.可选地，CG response timer是per HARQ process进行维护的。
4.可选地，该过程是per CG configuration per CG周期进行的。例如，假设网络侧配置了两个CG configuration，则UE需要对CG configuraton1/2对应的每个CG周期进行上述过程。
可选地，在CG response timer运行期间：
1.如果UE收到确认数据传输正确的指示，则停止(HARQ process对应的)CG response timer和/或CG timer。可选地，该确认数据传输正确的指示可以在PDCCH上承载。可选地，该确认数据传输正确的指示是per HARQ process进行指示的，可选地，一个PDCCH上可以携带一个或多个HARQ process的确认数据传输正确的指示。
2.可选地，如果UE收到一个确认数据传输正确的指示，重启T319定时器。
3.可选地，如果UE收到一个确认数据传输正确的指示，设置第一计数器值为0。
4.如果UE收到一个用于调度上行重传的PDCCH，则停止(HARQ process对应的)CG response timer和/或重启(HARQ process对应的)CG timer。
根据PDCCH的内容进行重传，在用于重传的PUSCH发送后，不管有没有潜在的measurement gap，UE在PUSCH后第一个PDCCH occasion启动CG response timer，启动/重启CG timer。
5.如果UE收到一个用于调度上行新传的PDCCH，则停止(HARQ process对应的)CG response timer和/或(HARQ process对应的)CG timer。
根据PDCCH的内容进行新传，在用于新传的PUSCH发送后，不管有没有潜在的 measurement gap，UE在PUSCH后第一个PDCCH occasion启动CG response timer，启动/重启CG timer。
6.如果UE收到一个用于调度下行传输的PDCCH而且对应调度的PDSCH被成功解码，则停止(HARQ process对应的)CG response timer和/或停止(HARQ process对应的)CG timer。
然后，UE解组装(disassemble)和解复用(demultiplex)MAC PDU。UE根据PDCCH的UCI资源指示信息，上报HARQ-ACK指示。
可选地，所述PDCCH携带了响应指示信息，所述响应指示信息指示该下行调度是响应哪个上行HARQ进程(例如，PDCCH携带响应指示信息，指示该下行调度是ID是0的上行HARQ进程)。
7.如果UE收到一个用于调度下行传输的PDCCH但对应调度的PDSCH没有被成功解码，UE根据PDCCH的UCI资源指示信息，上报HARQ-NACK指示。
可选地，PDCCH携带了响应指示信息，响应指示信息指示该下行调度是响应哪个上行HARQ进程(例如，PDCCH携带响应指示信息，指示该下行调度是ID是0的上行HARQ进程)。
8.UE假设最近一次步骤3中选择的第一参考信号(可以理解成和发送CG-PUSCH存在关联关系的第一参考信号)和DM-RS天线端口(可以理解成PDCCH的DMRS)具有相同的准正交特性(quasi co-location properties)。
可选地，在CG response timer超时后：
1.在该CG response timer超时后，对第二计数器加1；
2.如果第二计数器数值＝CG传输最大次数门限+1，即第二计数器数值大于配置授权传输最大次数门限时，则执行以下至少一项：
(1)向高层(RRC)上报一个失败/回退指示。
(2)结束基于配置资源的数据传输过程。
(3)MAC清除步骤1所述保存所述专属上行资源以及对应的HARQ信息。
(4)RRC清除步骤0所述的所有保存的资源和信息。
否则，执行步骤3资源选择过程。
3.可选地，CG传输计数器是per HARQ process进行维护的；如果所有HARQ process对应第二计数器数值中的最大值/最小值＝CG传输最大次数门限+1，即所有HARQ进程对应的第二计数器数值中的最大值或最小值大于配置授权传输最大次数门限时，则执行以下至少一项：

下面以只有一个CG配置时且采用第一种HARQ进程规则的基于配置资源的数据传输为例，对上述实施例中的方法进行说明。
步骤A(T0时刻)：UE通过RRC Release消息收到了专属上行资源。所述专属上行资源配置了一个CG configuration。
步骤B(T0-T1时段)：在收到上述配置后，UE(如：RRC层)在每个CG周期内， 如果在该CG周期内所有(有效的)上行传输时机上基于配置资源的数据传输过程都没有被触发，则第一计数器加1。
步骤C(T1时刻)：UE(如：RRC层)触发基于配置资源的数据传输过程被触发，此时RRC层指示MAC层基于配置资源的数据传输过程被触发，然后MAC层保存保存所述专属上行资源以及对应的HARQ信息，初始化专属上行资源。
