技术领域
本公开涉及通信技术领域,尤其涉及一种随机接入(Random Access,RA)的方法、设备及终端。
背景技术
在(5-th Generation,5G)移动通信系统中,终端可能只能支持一个比较小的工作带宽(如5MHz),而网络侧的一个小区会支持比较大的带宽(如100MHz),该大带宽中的终端工作的小带宽部分被称为带宽部分(Bandwidth Part,BWP)。从终端配置的角度来说,对于不同的终端功能,BWP可以作为是1个小区或1个小区下的BWP。
网络侧可配置终端有1个或多个BWP,并通过激活(activated)或去激活(deactivated)BWP的方式变换终端可以工作的BWP。通常,网络侧会配置1个默认的BWP(default BWP),当终端工作在该小区的其他BWP的时候,网络侧可以给终端配置1个在该小区的其他BWP工作的定时器,当该定时器超时的时候,终端会切换回该默认的BWP。
随机接入过程是终端和网络侧之间建立无线链路的必经过程,只有在随机接入完成之后,终端和网络侧之间才能正常进行数据互操作。随机接入过程主要分为:非竞争随机接入和竞争随机接入。
终端在某个激活的BWP上工作的时候,该BWP可能没有配置的随机接入资源,那么此时,如果终端要发起随机结果过程的时候可能会出现发起失败的情况,从而降低了终端和网络侧的通信成功率。

参见图1,图1是本公开实施例提供的随机接入方法的流程图。图1所示的方法可应用于终端。如图1所示,包括以下步骤101至103。
步骤101、获取随机接入配置信息。所述随机接入配置信息包括各BWP对应的随机接入资源。
在本公开实施例中,终端可接收网络侧发送的随机接入配置信息,或者根据与网络侧的预先约定,获取预先约定的随机接入配置信息。
其中,在此各BWP对应的随机接入资源可以理解为,每个BWP都具有对应的随机接入资源,其中,BWP和随机接入资源可以是一一对应的,还可能是多个BWP具有同一随机接入资源。
除了在所述随机接入配置信息中包括各BWP对应的随机接入资源,还可包括如下信息:
(1)随机接入资源是否用于竞争随机接入的指示信息;
(2)随机接入资源是否用于非竞争随机接入的指示信息;
(3)随机接入过程的带宽。
其中,所述随机接入资源包括以下信息中的一项或者多项:时间资源配置;频率资源配置;编码资源配置;空间资源配置。
不同BWP的随机接入资源可以是重合的,或者是不重合的,或者是部分重合的。也就是说,不同的BWP的随机接入资源可以是相同的,或者不同的;如果相同,还可以是部分相同。其中,重合的或部分重合的随机接入资源包括以下信息中的一项或者多项:时间资源配置;频率资源配置;编码资源配置;空间资源配置。
其中,所述时间资源配置包括以下信息中的一项或者多项:无线帧(如,系统帧号(System Frame Number,SFN);子帧(subframe);时隙(slot)。
其中,所述频率资源配置包括以下信息中的一项或者多项:频点标识;带宽(如协议约定的最小带宽5MHz);BWP标识(如默认的BWP的标识,或当前激活的BWP的标识);物理资源块标识;小区标识;子载波间隔。具体的,所述BWP标识包括以下信息中的一项或者多项:默认的BWP标识; 当前激活的BWP标识;当前非激活的BWP标识。
其中,所述编码资源配置包括:随机接入前导码(preamble)。
其中,所述空间资源配置包括以下信息中的一项或者多项:参考信号标识;同步信号块(Synchronous Signal Block,SSB)标识;信道状态信息参考信号(Channel State Information–Reference Signal,CSI-RS)标识;波束标识;波束对标识;传输节点标识;小区标识;小区组标识。
其中,随机接入过程的带宽应用于终端在随机接入过程中向网络侧发送消息的过程中,和/或从网络侧接收消息的过程中。
需要说明的是,上述各信息中的内容还可随着技术的发展做进一步的扩展,在本公开实施例,仅是举例说明了上述各信息中可能包括的内容。
步骤102、根据所述随机接入配置信息,获取终端当前激活的BWP对应的目标随机接入资源。
根据上述随机接入配置信息,终端可根据当前激活的BWP获得对应的随机接入资源,在此称为目标随机接入资源。
步骤103、利用所述目标随机接入资源发起随机接入过程。
根据随机接入配置信息所包括的不同内容,终端可发起不同类型的随机接入过程。例如,当所述随机接入资源是否用于竞争随机接入的指示信息表示所述随机接入资源用于竞争随机接入时,终端可利用所述目标随机接入资源发起竞争随机接入过程;当所述随机接入资源是否用于非竞争随机接入的指示信息表示所述随机接入资源用于非竞争随机接入时,终端可利用所述目标随机接入资源发起非竞争随机接入过程。又例如,当所述BWP标识包括默认的BWP标识时,终端则在所述默认的BWP上,利用所述目标随机接入资源发起随机接入过程。
在实际应用中,目标随机接入资源对应的BWP有可能不是终端当前激活的BWP,因此,为了进一步提高资源利用率,在此还可确定所述终端当前激活的BWP是否为所述目标随机接入资源对应的BWP。若所述终端当前激活的BWP不是所述目标随机接入资源对应的BWP,则激活所述目标随机接入资源对应的BWP,并在所述目标随机接入资源对应的BWP上,利用所述目标随机接入资源发起随机接入过程。同时,终端还可去激活所述终端当前激 活的BWP,向网络侧通知所述终端当前激活的BWP的信息,以及向网络侧通知所述目标随机接入资源对应的BWP的信息。那么,网络侧在收到上述信息后,即可利用终端激活的BWP向其发送数据。
此外,在发起随机接入过程后,对于终端和网络侧之间在后续过程中终端需要发送给网络侧的消息,终端均在所述终端当前激活的BWP上发送所述随机接入过程中需发送给网络侧的消息。而若所述终端当前激活的BWP被去激活,则停止随机接入过程,该停止的随机接入过程的类型包括:基于竞争的随机接入过程,或者基于非竞争的随机接入过程,或者同时包括基于竞争的随机接入过程和基于非竞争的随机接入过程。
本公开实施例中,当终端发起随机接入过程中,可根据随机接入配置信息获得当前激活的BWP所对应的目标随机接入资源,利用所述目标随机接入资源发起随机接入过程。由此可以看出,在本公开实施例中,由于可保证终端在当前激活的BWP上利用对应的资源发起随机接入过程,从而避免了现有技术中出现的终端在某个激活的BWP上工作时,而该BWP可能没有配置的随机接入资源所导致的随机接入过程失败的问题。因此,利用本公开实施例可提高终端和网络侧之间的通信成功率。
同时,在本公开实施例中,终端还可以根据随机接入类型判断是否停止对应的随机接入过程,从而提高随机接入的成功概率。
本公开实施例中,上述方法可以应用于终端,例如手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等。
其中,基于非竞争的随机接入过程如图2所示,竞争的基于竞争的随机接入过程如图3所示。其中,所述网络侧可如基站等。
如图2所示,为基于非竞争的随机接入的过程示意图,包括:
Msg0-1、基站向终端发送RA前导码分配(Preamble assignment),为终端分配用于非竞争随机接入的专用随机接入资源。
Msg1-1、终端根据Msg0-1指示的随机接入资源,在指定的随机接入资源上向基站发送指定的专用随机接入信号。
具体的,终端向基站发送RA前导码。
终端在发送Msg1-1后,根据Msg1-1的发送时间和频率的位置,计算网络侧调度Msg2-1的标识信息随机接入无线网络临时标识(Random Access Radio Network Temporary Identity,RA-RNTI)。计算方式如下:
RA-RNTI=1+t_id+10*f_id
其中,t_id是随机接入信号的子帧标识,f_id是随机接入信号的频域标识。
终端在发送Msg1-1后,在一个固定窗口随机接入响应窗口(Random Access Response window,RAR window)内监听下行信道以获取网络侧的反馈信息Msg2-1,其中控制信道为物理下行控制信道(Physical Downlink Control Channel,PDCCH),数据信道为物理下行共享信道(Physical Downlink Shared Channel,PDSCH),终端可以为该RAR window启动对应的定时器(如在RAR window开始时刻启动,在RAR window结束时刻停止)。该RAR window的开始位置为Msg1-1发送结束的子帧加上3个子帧,长度为网络配置的长度。
Msg2-1、基站向终端发送随机接入响应(Random Access Response),随机接入响应中包含:Msg1-1标识信息随机前导码标识(Random Access Preamble Identifier,RAPID);上行定时提前量信息(例如Timing Advance Command);上行发送授权信息(即UL Grant,上行授权);回退信息(Backoff Indicator,BI);临时终端标识信息(即Temporary C-RNTI)。如果终端接收随机接入响应(Random Access Response,RAR)失败,则根据RAR中指示的回退信息,确定下次发送随机接入的时刻。终端需要在整个RAR窗口内持续的监听,以接收对应的RAR消息。
如图3所示,为基于竞争的随机接入的过程示意图,包括:
Msg1-2、终端选择随机接入资源并利用该随机接入资源向基站发送所选的随机接入信号。
具体的,终端向基站发送RA前导码(Preamble)。其中RA-RNTI和RAR窗口(window)的计算方式同非竞争随机接入过程。
Msg2-2、基站接收到Msg1-2后,计算定时提前量TA,并向终端发送随机接入响应(Random Access Response),随机接入响应中至少包含该定时提前量信息(例如,TA)和针对Msg3的UL grant。终端需要在整个RAR窗口 内持续的监听,以接收对应的RAR消息。
Msg3-2、终端向基站发送调度传输(Scheduled Transmission)消息。具体的,终端在Msg2-2指定的UL grant上发送上行传输,不同随机接入原因Msg3上行传输的内容不同,比如对于初始接入,Msg3-2传输的是无线资源控制协议(Radio Resource Control,RRC)连接建立请求。
Msg4-2、基站向终端发送竞争解决(Contention Resolution)消息,终端根据Msg4-2可以判断随机接入是否成功。
Msg5、终端反馈配置完成消息。
在上述过程中,终端根据随机接入配置信息中包括的随机接入过程的带宽,在该带宽的范围内接收和发送消息。
