下文以NR移动通信系统及其后续的演进版本作为示例应用环境,以支持NR的基站和UE设备为例,具体描述了根据本发明的多个实施方式。然而,需要指出的是,本发明不限于以下实施方式,而是可适用于更多其它的无线通信系统,例如eLTE,通信系统,或者是NB-Iot系统,又或者是LTE-M系统。而且可以适用于其他基站和UE设备,例如支持eLTE/NB-Iot/LTE-M的基站和UE设备。
接入种类(access category,AC)
在由RRC层之上的上层触发的RRC连接恢复过程中,上层可以向RRC提供接入种类(access category,AC),在启动RRC连接恢复过程之前,UE将依据提供的AC进行接入控制流程。接入控制流程的结果有两者,一是禁止接入(access attempt is barred),还有一种是允许接入(access attempt is allowed)。
接入控制流程的操作如下:
如果针对上层提供的AC,其对应的定时器T390正在运行,那么针对该AC的接入是被禁止的;
如果T302正在运行,并且AC不是对应于取值为“0”或者取值为“2”的AC,那么针对该AC的接入也是被禁止的。
如果上述情况都不存在,那么根据提供的AC,UE可以依据系统信息中广播的和接入控制相关的参数执行接入禁止检查(Access barring check)步骤,根据该步骤的结果来确定接入控制流程的结果。在该步骤中,如果接入是被禁止的,那么UE对针对该AC启动其对应的定时器T390。
基于上述操作,当确定接入控制的结果是接入禁止时:
如果T302正在运行,并且针对AC取值为“2”的T390正在运行,那么UE会通知上层指示,除了AC取值为“0”的AC,其他AC的接入都是被禁止的;
如果T302正在运行,并且针对AC取值为“2”的T390没有运行,那么UE会通知上层,除了AC取值为“0”或者“2”的AC,其他AC的接入都是被禁止的;
如果T302没有在运行,那么UE会通知上层对应AC的接入被禁止。
当确定接入接入控制的结果是运行接入,那么UE也会通知上层对应AC的接入被允许。
依据接入控制的结果,如果是禁止接入,那么RRC连接恢复流程结束;如果是允许接入,那么UE可以继续执行RRC连接恢复流程中的其他操作,例如向基站发送RRC连接恢复请求消息等。
定时器T319和T319a
UE在启动RRC连接恢复的过程中,如果执行小数据传输的条件被满足,UE可以认为判定/认为(consider)该恢复过程是由小数据传输触发或者启动的,以及启动定时器T319a;
如果执行小数据传输的条件不能被满足,那么UE启动定时器T319。
这两个定时器都是用来管理RRC连接恢复过程的,当T319或者T319a运行超时时,UE将进入空闲态(IDLE),并执行相应的操作。
四步随机接入过程(4 step Random Access procedure,4-step RA)
如图1所示,UE执行4步随机接入过程包含下述步骤:
步骤S100:UE选定用于随机接入的随机接入资源。在这一过程中
-UE选定了用于发送的前导序列(preamble),将选定的preamble对应的序号设置为参数PREAMBLE_INDEX的值;以及
-在多个PRACH时机(PRACH occassions)中确定下一个可以用于传输的PRACH时机(determine the next available PRACH occasion from the PRACH occasions)。
步骤S101:UE在确定的PRACH时机上发送选定的preamble。
步骤S102:UE接收基站侧发来的随机接入响应(Random Access Response,RAR)。
如果在这个RAR中携带了UE在步骤S101中发送的preamble对应的序号(preamble index id),那么UE可以确定该RAR是发送给自己的。
在这样的RAR中会携带UL grant指示了用于传输消息3的PUSCH资源。
当接收到上述的RAR之后,UE会处理RAR中携带的UL grant,并将 它指示给下层。如果这是UE第一次成功的接收到上述RAR,那么UE从复用和组装实体(Multiplexing and assembly entity)中获取(obtain)用于发送的MAC PDU,并将它保存在消息3的缓存区(MSG3buffer)中。
如果UE在预定时间内没有接收到上述RAR,那么UE会将变量PREAMBLE_TRANSMISSION_COUNTER的值增加1,该变量的初始值为0。如果PREAMBLE_TRANSMISSION_COUNTER=preambleTransMax+1,那么UE认为随机接入过程没有成功完成,可以向上层指示随机接入问题。
步骤S103:UE在UL grant指示的PUSCH资源上发送消息3。
在这个消息3中,UE会携带用于竞争冲突解决的标识信息。
步骤S104:UE接收基站侧发送来的消息4。
在消息4中如果携带了UE在消息3中携带的标识信息,那么UE认为竞争冲突解决,随机接入过程成功完成。
如果UE在预定时间内没有接收到上述消息4,那么UE会将变量PREAMBLE_TRANSMISSION_COUNTER的值增加1,该变量的初始值为0。如果PREAMBLE_TRANSMISSION_COUNTER=preambleTransMax+1,那么UE认为随机接入过程没有成功完成,可以向上层指示随机接入问题。
由于在上述随机接入过程中UE经历了步骤S101~S104的消息传递过程,因此被称为“四步随机接入”(4-step RA)过程。
上述四步随机接入过程还可以被称为是第一类型的层1随机接入(Type-1 layer 1 Random Access Procedure,type 1 L1 RA)。从物理层(又称为层1,layer 1)的角度来看,type 1 L1 RA过程至少包含了在PRACH上传输随机接入前导序列(或者称为消息一的传输),以及随机接入响应消息(Random Access Response Message)的传输/接收,这个随机接入响应消息的传输是由PDCCH调度的,并且是在PDSCH上传输的;此外,在type 1L1RA过程中还可以包含随机接入响应中携带的上行授权所调度的PUSCH,以及随之而来的用于竞争冲突解决(contention resolution)的PDSCH。
两步随机接入过程(2 step Random Access procedure,2-step RA)
如图2所示,两步随机接入过程为
步骤S200:UE选定用于随机接入的随机接入资源。在这一过程中
-UE选定了用于发送的前导序列(preamble),将选定的preamble对应的序号设置为参数PREAMBLE_INDEX的值;以及
-在多个PRACH时机(PRACH occassions)中确定下一个可以用于传输的PRACH时机(determine the next available PRACH occasion from the PRACH occasions),以及
-确定对应于该前导序列的PUSCH资源。
步骤S201:UE向基站发送消息A(MSGA)。
其中,消息A包含preamble和消息A的负载(payload)。
其中,preamble在PRACH上发送,消息A的payload在PUSCH上发送。消息A的payload是被包装成MAC PDU在PUSCH上传输。当UE确定了用于发送消息A的时机时,如果这是UE第一次发送MSGA,那么UE从复用和组装实体(Multiplexing and assembly entity)中获取(obtain)用于发送的MAC PDU,并将它保存在消息A的缓存区(MSGA buffer)中。
步骤S202:UE接收基站发送的消息B(MSGB)。
其中消息B携带了用于竞争冲突解决的信息。如果消息B携带了UE在步骤S201中发送的preamble对应的序号(preamble index id),那么UE可以确定消息B是发送给自己的,那么UE认为竞争冲突解决,随机接入过程成功完成。
为了解决背景技术中提到的问题,以下,详细描述本发明的若干实施例。
