Description

信道传输方法、装置、终端、基站和存储介质

技术领域
本申请涉及无线通信领域,例如涉及一种信道传输方法、装置、终端、基站和存储介质。
背景技术
在窄带物联网(Narrow Band Internet of Things,NB-IOT)和增强机器类通信(eMTC,enhanced Machine Type Communication)地面网络中,为了终端(UE,User Equipment)节能,引入了PUR功能:针对业务模式固定的UE预配置物理上行共享信道(Physical Uplink Shared Channel,PUSCH)链路资源,RRC_IDLE或RRC_INACTIVE状态的UE可以在预配置的PUSCH资源上直接发送上行数据,从而节省掉物理随机接入信道(Physical Random Access Channel,PRACH)接入的过程,实现UE的功耗降低。然而PUR功能的使用前提是UE的定时提前(Timing Advance,TA)不变,而保障UE的TA不变的方式是UE处于静止状态,因此在NB-IOT和eMTC地面网络中,PUR功能只适用于静止UE。
但是对于非地面网络(Non-Terrestrial Networks,NTN),尤其是低轨卫星无线网络,即使UE处于静止状态,但是卫星会移动,也就是小区与卫星可能处于相对移动状态,导致给UE配置PUR资源的小区可能与最终为UE进行PUR传输的小区不为相同小区,UE的TA也在一直变化,因此,PUR功能无法应用在NTN网络中,现在NTN网络中亟需一种基于PUR功能进行信道传输的方法。

示例性的,图6是本申请实施例提供的一种信道传输方法的示例图,基站eNB通过专用信令配置终端UE的PUR资源配置,参见图6,一种信道传输方法可以包括如下过程:
Step 1:基站通过专用信令给UE配置PUR资源信息(也可记为PUR配置信息),所述PUR配置信息包含如下至少之一:PUR周期,PUR响应时间窗定时器PUR-ResponseWindowTimer、小区ID(Identity,标识),PUR-USS,PUSCH资源配置(UL grant),PUSCH资源(UL grant)开始的时域位置信息,PUSCH资源(UL grant)的频域位置信息,TA有效性定位器,用于TA判决的RSRP变化门限,USS监控的最大时长,PUR-RNTI,PUR资源的有效个数。PUR配置信息还可以包括:服务小区或邻区的专用preamble(前导),sounding(探测),SR(Scheduling Request,调度请求),CG资源。
所述PUR资源可以是UE当前驻留小区的,也可以是其他一个或多个小区的PUR资源(列表)。
Step 2:UE在PUR资源的时域位置前,判断PUR专用资源配置是否属于当前驻留小区;如果是,首先基于卫星定位等信息计算TA,或者基于历史TA记录信息获取TA值,然后用所计算的TA在PUR资源上进行专用PUR传输。
Step3:在PUR资源开始位置,如果UE有上行信息发送,则在PUSCH资源上利用Step2获取的TA信息直接发送PUSCH。
Step4:UE在发送PUSCH后,向后偏移n个子帧开始监控PUR-RNTI加扰的PDCCH(Physical Downlink Control Channel,物理下行控制信道),所述PDCCH用于下行PDSCH(Physical Downlink Shared Channel,物理下行共享信道)资源调度(DL Grant)或者用于PUR传输确认(PUR ACK)。
在Step1中:
如果PUR资源是多个小区的PUR资源列表,则所述资源配置信息可以按照PUR资源公共配置部分(比如PUR周期,PUR响应时间窗定时器PUR-ResponseWindowTimer)和PUR资源小区级别的配置部分(比如:小区ID,PUR-USS,PUSCH资源配置(UL grant),PUSCH资源(UL grant)开始的时域位置信息,PUSCH资源(UL grant)的频域位置信息,TA有效性定位器,用于TA判决的RSRP变化门限,PUR-RNTI,PUR资源的个数)来组织。
其中:PUSCH资源开始的时域位置信息可以采用如下方式之一表征:
(1)绝对时间:绝对时间为【时:分:秒:毫秒】格式,至少精确到毫秒。UE时钟来源于卫星时钟
(2)绝对时间和相对时间的方式表征:绝对时间为【时:分:秒】格式,至少精确到秒,UE时钟来源于卫星时钟;相对时间为:系统帧号+子帧号,来源于UE与基站的无线同步。
在Step 2中:如果UE基于历史TA记录信息获取TA值,则UE需要保存PUR资源时域位置的TA信息。所述保存的TA信息是否有效可以通过PUR TA有效性定时器(pur-TimeAlignmentTimer)和/或PUR TA有效性的RSRP变化门限来判断。
所述PUR TA有效性定时器(pur-TimeAlignmentTimer)和/或PUR TA有效性的RSRP变化门限可以按UE配置,或者作为PUR小区级别(PUR资源小区级别配置部分)配置(如果PUR资源是多个小区的PUR资源列表,则每个小区分别配置);
如果按UE配置,则PUR TA有效性定时器(pur-TimeAlignmentTimer)在UE收到PUR配置时启动或重启;在收到TAC MAC CE后重启;RSRP的变化门限以最近一次获得有效PUR TA时刻的RSRP测量值为参考。
如果作为PUR小区级别配置,则PUR TA有效性定时器(pur-TimeAlignmentTimer)在UE收到PUR配置时在该小区所对应的PUR资 源开始位置启动或重启;在收到该小区的TAC MAC CE后重启;PUR TA有效性的RSRP的变化以该小区最近一次获得有效PUR TA时的RSRP的测量值为参考。
在PUR资源配置的时域位置,如果UE驻留小区与PUR资源对应的小区不一致,则UE自动释放所述配置的PUR资源(可以释放UE级别的PUR资源,或者只释放该UE的PUR资源配置的时域位置对应的所述小区的PUR资源);同时,UE向基站发送所述PUR资源释放指示。
其中,参见图7,在Step1中,如果基站给UE配置的PUR资源信息不是UE当前驻留小区,则PUR配置信息里携带PUR资源对应的小区ID,所述小区ID可以为Physical Cell Identity(PCI)或者CGI(Cell Global Identity)。参见图7,如果基站给UE配置的PUR资源信息属于其他基站下的小区,则本基站首先向其他基站请求PUR资源,然后将其他基站分配的PUR资源配置给UE;
在图7中,Step 1:UE驻留基站2(eNB2)基于UE业务的时域位置,UE的移动轨迹、小区的移动轨迹计算UE在业务的时域位置所驻留的目标小区,然后向目标小区所归属的基站1(eNB1)请求PUR资源。所述PUR资源请求中至少包含如下信息之一:目标小区标识,PUR资源对应的Message Size,PUSCH资源的开始时域位置,PUSCH资源的周期,UE位置信息,UE移动轨迹信息,当前驻留小区的位置信息。
其中:step1中的目标小区标识和(UE位置信息,UE移动轨迹信息,当前驻留小区的位置信息)可以是二选一。
Step 2:目标小区所在基站基于UE业务的时域位置,UE的移动轨迹、小区的移动轨迹计算UE业务的时域位置所在小区,并为UE分配PUR资源,并将所分配的PUR资源传递给UE当前驻留基站。如果UE业务的时域位置有多个(比如周期性PUR业务、多个业务pattern),则所分配的PUR资源可能有多个(列表)。所述分配的PUR资源中至少包含如下信息之一:小区标识,PUR周期,PUR响应时间窗定时器PUR-ResponseWindowTimer、小区ID,PUR-USS,PUSCH资源配置(UL grant),PUSCH资源(UL grant)开始的时域位置信息,UL grant的频域位置信息,USS监控的最大时长,PUR_RNTI,TA有效性定位器,用于TA判决的RSRP变化门限,PUR-RNTI,PUR资源的有效个数。
参见图8,如果给UE分配PUR资源信息的基站是CU-DU分离架构,则CU首先向DU请求PUR资源,然后DU分配的PUR资源配置给UE。
在图8中,Step 1:CU向DU请求PUR资源,所述PUR资源请求中至少 包含如下信息之一:目标小区的标识信息,PUR资源对应的Message Size,PUSCH资源的开始时域位置,PUSCH资源的周期,UE位置信息,UE移动轨迹信息,当前驻留小区的位置信息。
Step 2:DU基于UE业务的时域位置,UE的移动轨迹、小区的移动轨迹计算UE业务的时域位置所在小区,并为UE分配PUR物理层资源,并将所分配的PUR资源传递给CU;
DU保存PUR资源的时频域信息,用于PUR接收。
CU存储PUR配置的安全密钥、AS上下文等完整信息,用于UE识别,数据完整性校验及安全解密,数据转发,业务流程建立等。
如果UE业务的时域位置有多个(比如周期性PUR业务、多个业务pattern),则所分配的PUR资源可能有多个(列表)。所述分配的PUR资源中至少包含如下信息之一:目标小区的标识信息,PUSCH资源配置(UL grant),PUSCH资源(UL grant)开始的时域位置信息,PUSCH资源(UL grant)的频域位置信息。
Step 3:当CU释放PUR资源时,指示DU释放分配的PUR资源。所述指示至少包含如下信息之一:目标小区的标识信息,PUR资源对应的时域和/或频域位置,PUSCH资源的周期,UE位置信息。
所述目标小区的标识信息可以为:小区CGI或CU所包含的小区索引。
所述Step1~Step3的信令交互可以是UE级别的无F1口连接的信令。和NR CU-DU分离时的CG资源请求区别在于:NR(New Radio)是在UE CONTEXT SETUP或UE CONTEXT MODIFICATION过程中进行CG资源分配的,涉及UE级别的F1连接,CG资源是给连接模式UE使用的;而本流程中的信令:只是为了分配和/或释放PUR资源,可以采用专门的资源请求和释放流程,可以没有完整的F1口UE上下文(UE的F1-U连接在资源分配完成后立即释放,或在资源配置给UE后立即释放),PUR资源是给空闲模式或RRC_INACTIVE状态的UE使用的。
图9是本申请实施例提供的一种定时提前更新方法的流程图,本申请实施例中适用于非地面网络中对支持PUR传输的情况,该方法可以通过软件和/或硬件方法实现,一般应用于UE,参见图9,本申请实施例提供的方法具体包括如下步骤:

在一实施例中,在上述申请实施例的基础上,所述根据接收的随机接入响应消息更新PUR资源的定时提前,包括:
步骤611、接收随机接入响应消息,启动随机接入竞争决议过程。
例如,接收到随机接入响应消息时,可以控制UE启动随机接入竞争决议过程。
步骤612、在随机接入过程中竞争决议成功的情况下,重新启动PUR对应的TA定时器。
例如,在随机接入过程的竞争决议成功时,可以控制UE重启PUR对应的TA定时器。
在一实施例中,在上述申请实施例的基础上,所述根据接收的随机接入响应消息更新PUR资源的定时提前,包括:
步骤621、接收随机接入响应消息,临时记录接收随机接入响应消息之前的NTA值并初始化TA定时器。
其中,NTA可为Timing offset between uplink and downlink radio frames at the UE,expressed in units of Ts(UE侧上行无线帧相对于下行无线帧的定时偏移值)。
在本申请实施例中,接收到随机接入响应消息时,记录接收随机接入响应消息之前的NTA值,并控制TA定时器启动或者重启以实现初始化。
步骤622、若竞争决议失败,则将NTA设置为临时记录的接收随机接入响应消息之前的NTA值,若竞争决议成功,则删除临时记录的接收随机接入响应消息之前的NTA值,并将PUR-TA定时器设置为TA定时器的值。
例如,若随机接入过程的竞争决议失败,则将NTA设置为记录的接收随机接入响应消息之前NTA值,若随机接入过程的竞争决议成功,则删除记录的NTA值,并将PUR-TA定时器设置为TA定时器的取值。
在一实施例中,在上述申请实施例的基础上,所述根据接收的随机接入响应消息更新PUR资源的定时提前,包括:
步骤631、接收随机接入响应消息,记录接收随机接入响应消息之前的NTA 值以及PUR-TA定时器的值。
例如,接收到随机接入响应消息时,记录NTA值和PUR-TA定时器的值。
步骤632、重启TA定时器以及PUA-TA定时器。
在本申请实施例中,分别控制TA定时器以及PUA-TA定时器重启以实现初始化。
步骤633、若竞争决议失败,则将NTA值恢复为临时记录的接收随机接入响应消息之前的NTA值以及,将PUR-TA定时器重新赋值为TA定时器取值与记录的PUR-TA定时器的值的和。
例如,在随机接入过程竞争决议失败时,将NTA设置为临时记录的接收随机接入响应消息之前的NTA值,PUR-TA定时器设置为Legacy-TA定时器取值与记录的PUR-TA定时器值的和。
步骤634、若竞争决议成功,则删除记录的接收随机接入响应消息之前的NTA值以及PUR-TA定时器的值。
例如,在随机接入过程竞争决议成功时,删除记录的NTA值以及PUR-TA定时器的值。
在一个示例性的实施方式中,可以将PUR TA与随机接入过程(Random Access Procedure,RAR)的TA进行耦合处理,在给UE配置了专用PUR资源后,当UE在IDLE或者inactive状态时,如果UE有上行数据且TA有效的情况下,UE就可以在这些PUR资源上发送。当UE进入连接态后,UE不会释放这些PUR资源。如果UE再次进入IDLE或者inactive状态时,这些PUR资源可能是可用的。当UE收到基站PDCCH或者PUSCH携带的TAC MAC CE校准命令(TAC),UE会更新自己的TA值,并启动关联PUR的TA有效性定时器(如果基站配置了PUR的TA有效性定时器)。在PUR TA有效性定时器未超时的情况下,PUR资源是可用的;否则,就不可用。
当UE在从IDLE或者inactive状态进入连接态时,UE可能会发起RACH过程,在收到RAR时,RAR会携带TAC。这时,UE会启动连接态时采用的TA timer,并更新TA值。但是标准没有描述目前的PUR TA Timer是否重启。上述过程将会导致以下问题:
1、此时,如果RAR不是本UE的,且UE后续RA一直失败,则更新TA后可能导致PUR TA Timer未超时,但TA不可用,从而导致PUR发送失败。
2、此时如果基站在连接态不发送TAC MAC CE,且UE不重启PUR TA Timer:由于TA值已经更新了,虽然TA值是有效的,但PUR TA Timer可能超 时,UE会误认为PUR不可用;如果基站在连接态不发送TAC MAC CE,但UE重启了PUR TA Timer:由于TA值已经更新了,虽然TA值是有效的,但PUR TA Timer可能超时,UE会误认为PUR不可用。
可以采用以下方式解决上述问题:
方法一:UE在收到RAR且RAR携带TAC命令时,UE重新启动PUR TA timer(如果配置了)。UE发起RACH过程后,UE会收到RAR,但是UE收到的RAR可能不是该UE的,可能是属于竞争冲突的其他UE的RAR,UE在RAR是无法分辨的。UE会收到RAR,UE就启动了PUR相关的TA timer。如果该RAR不是该UE的,RACH过程就失败了。接下来,UE会继续发起RACH过程,如果收到RAR,就继续重启PUR相关的TA timer,直到成功。当RACH过程成功了,UE同步成功了,PUR相关的TA timer也启动了。
方法二:UE发起RACH,竞争决议成功后,UE启动PUR相关的TA timer(如果配置了)。竞争决议成功后,那RAR肯定是属于该UE的,那RAR中携带的TA值也是属于该UE的,这时,UE再启动PUR相关TA timer。
方法三:UE在RA过程维护两个NTA值;UE收到RAR后,先临时记录RAR之前的NTA值(PUR-NTA),再开始维护legacy NTA,例如,使用RAR里的TAC作为当前的NTA值(apply the Timing Advance Command for this TAG),并启动或重启Legacy的TA Timer,但不重新启动PUR-TA Timer;如果RA竞争决议失败,则将legacy NTA值恢复为PUR-NTA。如果RA竞争决议成功,则删除PUR-NTA,并将PUR-TA Timer重新赋值为legacy的TA Timer。
方法四:UE在RA过程维护两个NTA值;UE收到RAR后,先临时记录RAR之前的NTA值(PUR-NTA)和PUR TA Timer的值,再开始维护legacy NTA(apply the Timing Advance Command for this TAG),并启动或重启Legacy的TA Timer,重新启动PUR-TA Timer;如果RA竞争决议失败,则将legacy NTA值恢复为PUR-NTA,并将PUR-TA Timer重新赋值为legacy的TA Timer+记录的PUR TA Timer。如果RA竞争决议成功,则删除记录的PUR-NTA和PUR TA Timer的值。

图13是本申请实施例提供的一种信道传输方法的流程图,本申请实施例中适用于非地面网络中对支持PUR传输的情况,该方法可以通过软件和/或硬件方法实现,一般集成在基站,参见图13,本申请实施例提供的方法具体包括如下步骤:
