Description

资源配置方法、终端设备和网络设备 技术领域
本申请涉及通信领域,更具体地,涉及一种资源配置方法、终端设备和网络设备。
背景技术
在非地面通信网络(Non-Terrestrial Networks,NTN)***中,由于终端设备与卫星之间的通信距离很远,信号传输的往返传输时间(Round Trip Time,RTT)远大于地面通信***的RTT,传输时延(Propagation delay)达到几十到几百毫秒不等,这与普通的地面***的时延相差很大。另一方面,关于终端设备的随机接入过程,终端设备在随机接入尝试时发送前导码(preamble),并在随机接入响应(Random Access Response,RAR)窗口(window)等待网络的响应消息,如果在窗口内没有接收到响应消息,则终端设备判定本次随机接入尝试失败,之后可再次发起随机接入尝试。
由于卫星通信***的传输时延远大于地面***的时延,因而对于卫星***,终端需要较长时间才能确定一次随机接入尝试是否成功,进一步,如果终端设备判定本次随机接入尝试失败,终端需要继续等待很长时间才能确定下一次随机接入尝试是否成功,大时延特性降低了用户体验。

为了清楚地阐述本申请实施例的思想,首先对通信***中随机接入过程的相关内容进行简要描述。
1)关于5G***
5G***的主要应用场景包括:增强移动宽带(Enhanced mobile broadband,eMBB)、高可靠低时延通信(Ultra reliability and low latency communication,URLLC)和大规模机器类通信(Massive Machine Type Communications,mMTC)。5G网络环境中,为了达到降低空口信令、快速恢复无线连接、快速恢复数据业务等目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即非激活态(RRC_INACTIVE),其有别于空闲态(RRC_IDLE)和连接态(RRC_CONNECTED)。
空闲态(RRC_IDLE)下,移动性为基于UE的小区选择/重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。基站侧不存在UE接入层(Access Stratum,AS)上下文,不存在RRC连接。
连接态(RRC_CONNECTED)下,存在RRC连接,基站和UE存在UE AS上下文。网络侧知道UE的位置是小区级别的。UE和基站之间可以传输单播数据。
非激活态(RRC_INACTIVE)下,移动性为基于UE的小区选择/重选,存在CN-NG-RAN之间的连接,UE AS上下文存在某个基站上,寻呼由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。
2)关于随机接入过程
按照随机接入资源的类型划分,随机接入过程可分为基于竞争的随机接入(Contention Based RACH,CBRA)和基于非竞争的随机接入(Contention Free RACH,CFRA)。随机接入资源一般包括随机接入机会(RACH Occasion,RO)资源配置和前导码(preamble)资源配置。对于CBRA,终端发起随机接入过程使用的RO和preamble是小区所有终端设备共用的或称公共的;对于CFRA,终端发起随机接入过程使用的RO和preamble是小区专门分配给终端使用的。四步随机接入过程以及两步随机接入过程均支持CBRA和CFRA的随机接入资源配置。
通常,一次随机接入过程包括至少一次随机接入尝试,终端在一次随机接入尝试发送preamble后,在随机接入响应(Random Access Response,RAR)窗口(window)等待网络发送的响应消息,如果RAR窗口内没接收到响应消息,则终端设备判定本次随机接入尝试失败,在回退指示(Backoff Indicator,BI)所指示的时间后再次发起随机接入尝试,如果随机接入尝试达到最大尝试次数后仍然没有成功,则终端设备判定本次随机接入过程失败。
3)关于卫星通信***
卫星可以分为GEO卫星、MEO卫星或LEO卫星,根据轨道高度的不同,GEO卫星的覆盖直径可达数千公里,MEO卫星或LEO卫星的覆盖直径从几十公里到上千公里不等,而地面小区通常覆盖直径为几百米到上千米,卫星小区的覆盖面积远大于地面小区。卫星的轨道高度从几百公里到几万公里不等,终端发送的信号需要几毫秒到几百毫秒才能得到卫星小区的响应,因此,大时延是卫星通信的基本特点。
由于卫星通信***的信号传播时延远大于地面***的时延,终端需要较长时间(几毫秒到几百毫秒不等,取决于卫星高度)才能确定一次随机接入尝试是否成功,进一步,如果本次随机接入尝试失败, 终端需要再次等待很长时间才能确定下一次随机接入尝试是否成功,因此,在卫星***中终端需要花费比地面***长的多的时间才能完成随机接入过程,导致时延过长,影响***整体性能,用户体验较差。
为此,本申请实施例提供一种资源配置方法,应用于终端设备,参考图2,该方法包括:
S101,终端设备接收网络设备发送的第一配置信息,所述第一配置信息包括一组或多组随机接入资源配置,所述第一配置信息用于指示所述终端设备根据所述一组或多组随机接入资源配置发起随机接入过程。
根据本申请的实施例,网络设备可为终端发送一组或多组随机接入资源配置信息,终端可根据当前情况从中选择一组适合的随机接入资源配置发起随机接入过程,可在一定程度上提高网络成功检测到MSG1消息(四步随机接入过程)或MSGA消息(二步随机接入过程)的概率,减少终端随机接入尝试的次数,因此,利用本申请的实施例能够减少随机接入过程的耗时,缩短时延,提高***整体性能,提高用户体验度。
相对应地,本申请实施例还提供了一种资源配置方法,应用于网络设备,参考图3,该方法包括:
S201,网络设备向终端设备发送第一配置信息,所述第一配置信息包括一组或多组随机接入资源配置,所述第一配置信息用于指示所述终端设备根据所述一组或多组随机接入资源配置发起随机接入过程。
根据本申请的实施例,网络设备可为终端设备发送一组或多组随机接入资源配置信息,终端设备可根据当前情况从中选择一组适合的随机接入资源配置发起随机接入过程,可在一定程度上提高网络设备成功接收终端设备发送的随机接入信号的概率,减少终端设备随机接入尝试的平均次数,因此,利用本申请的实施例能够减少随机接入过程的平均耗时,缩短平均时延,提高***整体性能,提高用户体验度。
根据本申请的实施例,可选地,单组所述随机接入资源配置属于第一类随机接入资源配置或者第二类随机接入资源配置,具体地,
·第一类随机接入资源配置包括专用的随机接入前导码根序列相关配置,专用的随机接入前导码根序列相关配置与预设信息存在第一关联关系;
·第二类随机接入资源配置包括公共随机接入前导码根序列相关配置。
也就是说,本申请的实施例可为终端配置至少两类随机接入资源配置,一类为常规的公共随机接入前导码根序列相关配置(属于第二类随机接入资源配置),另一类为专用的随机接入前导码根序列相关配置(属于第一类随机接入资源配置),该专用的随机接入前导码根序列相关配置与预设信息存在第一关联关系。
根据本申请的实施例,可选地,所述预设信息可包括终端设备类型标识和/或***应用场景标识,则终端设备可根据自身所属的终端设备类型和/或自身所处的应用场景,选择适合的随机接入资源配置发起随机接入过程,能够提高网络设备成功检测到四步随机接入过程的MSG1消息或者二步随机接入过程的MSGA消息的概率,例如,网络设备可以同时配置不同长度的随机接入前导码相关配置,网络设备检测不同长度的随机接入前导码的成功概率是不同的。
根据本申请的实施例,可选地,在本申请的多种实施例中,终端设备可基于以下至少一种方式确定自身所属的终端设备类型:
(1)根据预设的类型划分规则确定自身类型;
(2)根据出厂设置中的终端设备类型标识确定自身类型;
(3)根据非接入层(Non Access Stratum,NAS)过程提供的终端设备类型标识确定自身类型。
根据本申请的实施例,可选地,关于终端设备的类型划分规则(可以理解为前述根据预设的类型划分规则确定自身类型),可以按照以下至少一者划分:
·终端设备支持的发射天线的个数;
·终端设备支持的接收天线的个数;
·终端设备支持的双连接能力;
·终端设备支持的载波聚合能力;
·终端设备支持的带宽组合能力;
·终端设备支持的最大发射功率等级;
·终端设备支持的无线接入技术RAT类型;
·终端设备支持的带宽大小;
·终端设备是否对时延要求敏感。
根据本申请的实施例,可选地,终端设备所处的***应用场景可包括以下至少一者:地面通信场景、卫星通信场景、GEO场景、MEO场景、LEO场景、时延敏感型场景、非时延敏感型场景、紧急通信场景。
根据本申请的实施例,可选地,所述第一关联关系可以为显式关系,也可以为隐式关系,其中,
(1)在所述第一关联关系为显式关系的情况下,所述第一配置信息还包括终端设备类型标识和/或***应用场景标识。
(2)在所述第一关联关系为隐式关系的情况下,所述第一关联关系可通过协议预定义。
根据本申请的实施例,可选地,所述专用的随机接入前导码根序列相关配置与所述终端设备类型标识之间的所述第一关联关系为以下至少一者:一对一映射、一对多映射、多对多映射。可选地,所述专用的随机接入前导码根序列相关配置与所述***应用场景标识之间的所述第一关联关系为以下至少一者:一对一映射、一对多映射、多对多映射。
如前所述,本申请实施例的终端设备可根据自身所属的终端设备类型和/或自身所处的应用场景,来选择适合的随机接入资源配置发起随机接入过程,也就是说,本申请实施例的终端设备可以根据自身所属的终端设备类型选择适合的随机接入资源配置,也可以根据自身所处的应用场景选择适合的随机接入资源配置,还可以同时考虑自身所属的类型以及自身所处的应用场景来选择随机接入资源配置。以下示意性地描述多种资源选择方式:
(I)若所述第一配置信息包括所述第一类随机接入资源配置和所述第二类随机接入资源配置,并且,所述终端设备的类型不属于所述第一类随机接入资源配置关联的终端设备类型以及/或者所述终端设备所处的应用场景不属于所述第一类随机接入资源配置关联的应用场景,则所述终端设备使用所述第二类随机接入资源配置发起随机接入过程;
(II)若所述第一配置信息包括所述第一类随机接入资源配置,并且,所述终端设备的类型属于所述第一类随机接入资源配置关联的终端设备类型以及/或者所述终端设备所处的应用场景属于所述第一类随机接入资源配置关联的应用场景,则所述终端设备使用所述第一类随机接入资源配置发起随机接入过程;
(III)若所述第一配置信息包括所述第二类随机接入资源配置且不包括所述第一类随机接入资源配置,则所述终端设备使用所述第二类随机接入资源配置发起随机接入过程。
上述描述中提供了多种(超过3种)资源选择方式,均能够实现本申请实施例的目的,下文将通过具体的例子进行详细说明。
在本申请的一些实施例中,可选地,所述第一配置信息还可以包括第一阈值,其中,如果所述终端设备对当前服务小区或者目标小区的测量结果符合第一条件,则允许所述终端设备使用所述第一类随机接入资源配置发起随机接入过程;其中,所述第一条件为所述测量结果小于或等于所述第一阈值,或者,所述第一条件为所述测量结果大于或等于所述第一阈值。
进一步,可选地,如果所述终端设备对当前服务小区或者目标小区的测量结果不符合所述第一条件,则所述终端设备使用所述第二类随机接入资源配置发起随机接入过程。
基于本申请的实施例,将终端设备对当前服务小区或目标小区的测量结果与网络配置的第一阈值进行比较,当测量结果足够大(或足够小)时,允许终端设备使用第一类随机接入资源配置,也就是终端设备可使用专用的随机接入前导码根序列相关配置发起随机接入过程,否则,终端设备只能使用公共的随机接入前导码根序列相关配置发起随机接入过程。
需要说明,在本申请的实施例中,可将上述基于第一阈值的处理与前文提供的多种资源选择方式(例如终端设备可根据自身所属的终端设备类型和/或自身所处的应用场景选择适合的随机接入资源配置)结合使用,例如,如果第一配置信息中既包括一组或多组随机接入资源配置,还包括该第一阈值信息,以下示意性地描述几种可能的方式处理:
方式一:先判断终端设备对当前服务小区或目标小区的测量结果是否符合该第一条件,如果符合(说明允许终端设备使用第一类随机接入资源配置),则再根据终端设备自身终端设备类型和/或所处应用场景,在第一类随机接入资源配置和/或第二类随机接入资源配置中选择适合的随机接入资源配置;如果不符合(说明不允许终端设备使用第一类随机接入资源配置),则终端只能使用第二类随机接入资源配置。
方式二:先根据终端设备自身类型和/或所处应用场景,在第一类随机接入资源配置和/或第二类随机接入资源配置中选择适合的随机接入资源配置,选定后,还需判断终端设备对当前服务小区或目标小区的测量结果是否符合该第一条件,如果第一条件被满足(说明允许终端设备使用第一类随机接入资源配置),且选出的随机接入资源配置属于第一类随机接入资源配置或第二类随机接入资源配置,则可以使用选出的随机接入资源配置;如果第一条件不被满足(说明不允许终端设备使用第一类随机接入资源配置),而选出的随机接入资源配置属于第一类随机接入资源配置,这时不允许使用选出的随机接入资源配置,应使用第二类随机接入资源配置。基于描述的规则逻辑还可确定其余多种情况下的资源选择方式。
在本申请的一些实施例中,可选地,所述第一配置信息还可以包括第二阈值,并且,所述一组或多组随机接入资源配置包括至少一组专用随机接入前导码根序列相关配置以及一组公共随机接入前导码根序列相关配置;其中,所述专用随机接入前导码根序列相关配置是根据小区测量结果设置的。
进一步,可选地,如果所述终端设备对当前服务小区或者目标小区的测量结果符合第二条件,则所述终端设备使用所述至少一组专用随机接入前导码根序列相关配置发起随机接入过程;其中,所述第二条件为所述测量结果小于或等于所述第二阈值,或者,所述第二条件为所述测量结果大于或等于所述第二阈值。
再进一步,可选地,如果所述终端设备对当前服务小区或者目标小区的测量结果不符合第二条件,则所述终端设备使用所述公共随机接入前导码根序列相关配置发起随机接入过程。
基于本申请的实施例,可单独根据终端的测量结果大小选择适合的随机接入资源配置,例如,终端设备对当前服务小区或者目标小区的测量结果符合第二条件时,可选择一组专用随机接入前导码根序列相关配置发起随机接入过程,如果不符合该第二条件,则使用公共随机接入前导码根序列相关配置发起随机接入过程。
在本申请的多种实施例中,可选地,所述测量结果包括小区级测量结果或者波束级测量结果。可选地,所述测量结果包括以下至少一者:参考信号接收功率RSRP、参考信号接收质量RSRQ、信号与干扰加噪声比SINR。所述第一阈值和/或第二阈值均可以按照RSRP、RSRQ以及SNIR中的至少一者进行定义。
在本申请的多种实施例中,可选地,所述一组或多组随机接入资源配置中的至少一组随机接入资源配置还包括:与本组中随机接入前导码根序列相关配置关联的一个或多个消息A物理上行共享信道MSGA PUSCH资源配置和/或一个或多个随机接入机会RO资源配置。
基于本申请的实施例,网络设备既可为终端设备配置专用的随机接入前导码根序列相关配置,同时还可配置多个MSGA PUSCH资源和/或多个RO资源,前述任一随机接入资源既可以是公共的随机资源配置,用于基于竞争的随机接入过程,也可以是专用的随机资源配置,用于非竞争的随机接入过程。在发起随机接入尝试时,终端设备可选择使用不同的随机接入资源配置发起多次随机接入尝试,可提高随机接入成功的概率。
在本申请的一些实施例中,可选地,所述第一配置信息用于基于非竞争的随机接入过程的资源配置,所述第一配置信息包括包含有一个或多个专用RO资源的专用随机接入资源配置。可选地,所述一个或多个专用RO资源可以与同步参考信号SSB(Synchronization signal/physical broadcast channel block,SS/PBCH block)关联配置或者独立于SSB进行配置。
根据本申请的实施例,可选地,所述专用随机接入资源配置还包括一个或多个专用RO资源对应的专用随机接入前导码相关配置,和/或,包括一个或多个专用RO关联的一个或多个专用MSGA PUSCH资源配置。
根据本申请的实施例,可选地,所述包含一个或多个专用RO资源的专用随机接入资源配置可以属于同一组基于非竞争的随机接入资源配置,也可以属于多组基于非竞争的随机接入资源配置。
换句话说,网络设备可为终端设备配置一组基于非竞争的随机接入资源配置,也可以为终端配置多组基于非竞争的随机接入资源配置,其中,每组基于非竞争的随机接入资源配置中包括一个或多个专用RO资源以及该一个或多个专用RO资源对应的专用随机接入前导码相关配置和/或该一个或多个专用RO关联的一个或多个专用MSGA PUSCH资源配置,在一次随机接入过程中,终端可使用多组随机接入资源发起多次随机接入尝试,换句话说,终端设备每次发起随机接入尝试均可以在上述多组专用随机接入资源中选择一组,通过随机接入资源的差异化配置提高随机接入成功的概率。
在本申请的一些实施例中,可选地,所述第一配置信息还包括第一指示信息,用于指示是否允许所述终端设备在一次随机接入尝试对应的随机接入响应RAR窗口超时之前发起新的随机接入尝试。
按照已有规定,终端设备需要等待RAR窗口超时才能确定本次随机接入尝试失败,并且需要在确定本次随机接入尝试失败后再等待一段时间后,才能再次发起新的随机接入尝试,那么,如果终端设备发生若干次随机接入尝试失败,终端设备需要等待的时间将会很长。鉴于此,按照本申请的实施例,可允许终端设备在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试,通过连续多次发送,网络设备只要成功检测任何一次随机接入尝试过程发送的随机接入信号就可以认为本次随机接入过程成功,可减少随机接入过程的平均耗时,终端设备不需要等待确认上一次随机接入尝试失败,就能发送新的随机接入尝试(例如可使用相同的随机接入资源发起新的随机接入尝试,也可使用不同的随机接入资源发起新的随机接入尝试),网络设备只要成功检测到连续多次发送的随机接入尝试中的至少一次,终端设备就能收到RAR响应,完成随机接入过程,可节省终端设备随机接入过程平均等待时间,达到压缩耗时的目的。
在本申请的一些实施例中,可选地,若所述终端设备需要发起多次随机接入尝试,所述终端设备可以根据所述一组或多组随机接入资源配置中的相同的随机接入资源配置发起多次随机接入尝试;或者,所述终端设备还可以根据所述一组或多组随机接入资源配置中的不同的随机接入资源配置发起多次随机接入尝试。
基于本申请的实施例,终端可使用相同的随机接入资源配置发起新的随机接入尝试,也可使用不同的随机接入资源配置发起新的随机接入尝试,例如,可基于本申请前文描述的网络设备的多种配置方式、终端设备的多种选择方式,来确定每一次随机接入尝试使用的随机接入资源配置,可以使用与上一次相同的随机接入资源配置,也可以使用与上一次不同的随机接入资源配置,均可达到本申请实施例的目的。
需要说明,无论是否允许终端设备在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试,以上操作均适用,也就是说,如果终端设备只能在确定本次随机接入尝试失败后才能发起下一次随机接入尝试,或者,如果终端设备不需要确认本次随机接入尝试失败即可发起下一次随机接入尝试(RAR窗口内再次发送随机接入尝试),那么终端设备在发起下一次随机接入尝试时,均可以使用与上一次相同或不同的随机接入资源,例如,可以使用与上一次相同的RO位置,也可以使用与上一次不同的RO位置以实现频分增益,当然终端设备发起的连续两次随机接入尝试使用的随机接入前导码相关配置和/或MSGA PUSCH资源也可以相同或者不同,本申请对此不进行限制。
在本申请的一些实施例中,可选地,所述第一指示信息对应的方式还可与前述基于所述第一关联关系或者基于一个或多个专用RO资源的对应的方式组合使用,规则解释如下:
在所述第一指示信息对应的随机接入方式与所述第一关联关系对应的随机接入资源选择方式组合使用时,终端设备首先基于所述第一关联关系对应的随机接入资源选择方式选择终端设备应该使用的随机接入资源(所述随机接入资源至少包括随机接入前导码相关配置),然后终端设备可以在一次随机接入尝试对应的RAR窗口超时之前使用选择的随机接入资源发起新的随机接入尝试。
在所述第一指示信息对应的随机接入方式与所述基于包含一个或多个专用RO资源的随机接入资源配置方式组合使用时,终端设备可以在一次随机接入尝试对应的RAR窗口超时之前使用相同或者不同位置的专用RO资源发起新的随机接入尝试。
在本申请的一种实施方式中,可选地,所述第一指示信息包括一个比特的指示信息,通过比特‘0’或者‘1’取值通知终端设备激活或者去激活对应的功能(即:终端设备是否允许在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试)。
在本申请的一种实施方式中,可选地,所述第一指示信息包括第三阈值,只有在终端设备测得的当前服务小区或者目标小区的测量结果符合第三条件时,才允许终端设备可以在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试;否则,如果所述终端设备对当前服务小区或者目标小区的测量结果不符合第三条件,则不允许所述终端设备在一次随机接入尝试对应的随机接入响应RAR窗口超时之前发起新的随机接入尝试,其中,所述第三条件为所述测量结果小于或等于所述第三阈值,或者,所述第三条件为所述测量结果大于或等于所述第三阈值。
可选地,所述第三阈值可以针对小区级测量结果或者针对波束级测量结果定义的,所述第三阈值对应的测量结果可以是RSRP、RSRQ以及SINR中的至少一种。
在本申请的一种实施方式中,可选地,所述第一指示信息包括一个比特的指示信息和第四阈值,其中,通过比特‘0’或者‘1’取值通知终端设备激活或者去激活对应的功能,只有在对应的功能(允许终端设备在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试)为激活状态并且终端设备对当前服务小区或者目标小区的测量结果符合第四条件的情况下,才允许终端设备在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试;其余情况下,均不允许终端设备在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试。其中,所述的其余情况可能包括如下几种情况:
(1)该一个比特指示对应的功能为去激活状态,终端设备对当前服务小区或者目标小区的测量结果符合第四条件;
(2)该一个比特指示对应的功能为激活状态,终端设备对当前服务小区或者目标小区的测量结果不符合第四条件;
(3)该一个比特指示对应的功能为去激活状态,终端设备对当前服务小区或者目标小区的测量结果不符合第四条件。
也就是说,在上述任一种情况下,均不允许终端设备在一次随机接入尝试对应的RAR窗口超时之前发起新的随机接入尝试。
其中,所述第四条件为所述测量结果小于或等于所述第四阈值,或者,所述第四条件为所述测量结果大于或等于所述第四阈值。
根据本申请的实施例,可选地,所述第一配置信息还包括第一时间间隔阈值和/或一个RAR窗口内允许终端设备连续发起随机接入尝试的最大次数配置;所述第一时间间隔阈值用于指示所述终端设备连续发起两次随机接入尝试之间的最小时间间隔,所述最大次数配置规定了一个RAR窗口内允许终端设备连续发起随机接入尝试的最大次数。
需要说明的是,如果一个RAR窗口内允许终端设备连续多次发起随机接入尝试,那么终端设备在统计一次随机接入过程发起的随机接入尝试次数时,发生在一个RAR窗口内的多次随机接入尝试既可以只算作一次随机接入尝试或者按照实际多次尝试计算,本申请对此不做限制。
举例说明,网络设备规定在一次随机接入过程中最多允许终端设备发送6次随机接入尝试,终端在第一个RAR窗口发送了2次随机接入尝试,在第二个RAR窗口发送了3次随机接入尝试,第三个RAR窗口发送了1次随机接入尝试,终端设备可以认为本次随机接入过程只发送了3次随机接入尝试(按照RAR窗口个数计算),也可能认为自身已经发送了6次随机接入尝试(按照实际随机接入尝试次数计算)。
根据本申请实施例,可选地,所述第一配置信息还包括第一有效时间;在所述第一有效时间之内,所述第一配置信息有效;超出所述第一有效时间后,所述第一配置信息失效。
根据本申请实施例,可选地,所述第一配置信息通过***广播消息或者专用信令携带。
根据本申请的实施例,可选地,所述第一配置信息可通过如下至少一者激活:专用信令、媒体接入控制层控制单元(Media Access Control Control Element,MAC CE)、下行控制信息(Downlink Control Information,DCI)、寻呼短消息、寻呼消息。
以上通过多个实施例描述了本申请实施例资源配置方法的实现方式,以下基于本申请至少一个实施例,提供多个具体的例子,描述本申请实施例的多种实现思路以及实现过程。
实施例1
图4示意性地示出本申请实施例的终端设备获取第一配置信息的流程示意图,其中,步骤1:终端设备通过***广播消息或者专用信令接收接入网设备发送的第一配置信息,所述第一配置信息用于指导终端设备选择合适的随机接入资源和/或指示终端设备是否允许在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试。
为了实现上述处理,可采用多种思路设计具体的实现过程,作为示例,以下提供三种示意性思路。
●思路1:网络设备为终端设备配置特殊的(或称专用的、专用的)随机接入前导码相关配置(第一类随机接入资源配置),终端设备可根据自身所属的终端设备类型和/或自身所处的应用场景,从中选择适合的随机接入前导码相关配置发起随机接入过程,可提高终端设备发送的四步随机接入过程MSG1消息或者二步随机接入过程MSGA消息被网络设备成功检测的概率(其中不同配置长度的随机接入前导码解码成功率不同),可减少随机接入过程的平均耗时。
●思路2:网络设备为终端设备配置多个专用RO,终端可采取以下行为方式:
·行为1:终端设备只能在确定前一次随机接入尝试失败(即终端设备在该随机接入尝试关联的RAR窗口内未接收到网络设备响应)后才能发起下一次随机接入尝试,例如,每一次随机接入尝试可以使用相同的RO位置,也可以使用不同的RO位置以实现频分增益。
·行为2:允许终端设备在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试,已有机制下终端设备必须等待RAR窗口超时才能确定本次随机接入尝试失败,并且需在确定本次随机接入尝试失败的前提下继续等待一段时间后才能再次发起下一次随机接入尝试,如果终端设备发生若干次随机接入尝试失败,终端需要等待的时间将更长。本思路2通过连续多次发送的设计可减少随机接入过程的平均耗时,因为终端设备不需要一直等待上一次随机接入尝试失败确认,就能发送新的随机接入尝试,网络设备如果能成功检测连续多次发送的随机接入尝试中的至少一次,终端设备就能收到RAR响应,进而完成随机接入过程,可压缩随机接入过程平均耗时。
●思路3:将前述的思路1与思路2的方案进行叠加,也就是,网络设备既给终端配置特殊的随机接入前导码相关配置,同时也给终端设备配置多个专用RO资源,可强化压缩耗时的效果。
实施例2
在本实施例中,第一配置信息包含针对不同终端类型和/或不同应用场景的随机接入前导码相关配置。本实施例对应实施例1中的思路1。
具体来看,随机接入前导码相关配置可至少包括一个或者多个随机接入前导码根序列相关配置,此时随机接入前导码根序列相关配置与终端类型和/或应用场景的关联关系(可称为第一关联关系)是隐式的,示例性地可包含如下三种配置方式:
(1)隐式配置方式1:网络设备为特殊类型终端配置专用的随机接入前导码根序列相关配置,那么如果该专用的随机接入前导码根序列相关配置在配置中出现且终端设备属于特殊类型终端,则该类型终端设备在发起随机接入过程时可使用专用的随机接入前导码根序列相关配置;否则,终端只能使用公共的随机接入前导码根序列相关配置(第二类随机接入资源配置)。
表1
针对特殊终端类型 专用的随机接入前导码根序列相关配置
针对所有终端类型 公共的随机接入前导码根序列相关配置
表1列出了随机接入前导码根序列相关配置的隐式方式1,其中,
a)网络设备如果仅配置了公共的随机接入前导码根序列相关配置,则所有类型终端都只能使用公共的随机接入前导码根序列相关配置;
b)只有专用的随机接入前导码根序列相关配置在配置中出现且终端属于特殊类型终端设备,终端设备才能使用专用的随机接入前导码根序列相关配置;
c)其他情况下,例如专用的随机接入前导码根序列相关配置在配置中出现但终端不属于特殊类型终端,则终端只能使用公共的随机接入前导码根序列相关配置;
关于上述的终端类型,可基于如下至少一种维度对终端进行分类:终端设备支持的发射天线的个数、终端设备支持的接收天线的个数、终端设备支持的双连接能力、终端设备支持的载波聚合能力、终端设备支持的带宽组合能力、终端设备支持的最大发射功率等级、终端设备支持的无线接入技术RAT类型、终端设备支持的带宽大小、终端设备是否对时延要求敏感;
在本申请的一些实施例中,可以按照单一维度的特征信息对终端进设备行分类。比如,按照终端设备最大发射功率等级分类,将最大发射功率P低于一个阈值的终端划分为一类,则高于阈值的属于另外一类;当然使用多个阈值划分更多的终端类型的方式也是允许的,本申请对此不做限制;再比如,将支持卫星通信的终端划分为一类,将不支持卫星通信的终端划分为另一类。其余维度的单一特征信息分类的方式与此类似,不再赘述。
在本申请的一些实施例中,也可以按照多维度的复合特征信息对终端进行分类。比如,将终端最大发射功率P高于一个阈值且支持卫星通信的终端分为一类,不同于此情况的终端划分为另一类,等等。本申请对于基于至少两种特征信息进行终端分类的方式不进行限制,具体分类方式不再赘述。
(2)隐式配置方式2:网络为特殊应用场景的终端配置专用的随机接入前导码根序列相关配置。
表2
针对特殊应用场景 专用的随机接入前导码根序列相关配置
针对所有应用场景 公共的随机接入前导码根序列相关配置
表2列出了随机接入前导码根序列相关配置的隐式方式2,其中,
a)网络设备如果仅配置了公共的随机接入前导码根序列相关配置,则所有应用场景下终端都只能使用公共的随机接入前导码根序列相关配置;
b)只有专用的随机接入前导码根序列相关配置在配置中出现且终端识别当前通信***属于特殊应用场景,终端才能使用专用的随机接入前导码根序列相关配置;
c)其他情况下,如专用的随机接入前导码根序列相关配置在配置中出现但当前通信***不属于特殊应用场景,则终端也只能使用公共的随机接入前导码根序列相关配置;
关于特殊的应用场景,可以基于如下至少一种维度进行分类:地面通信场景、卫星通信场景、GEO场景、MEO场景、LEO场景、时延敏感型场景、非时延敏感型场景、紧急通信场景。
在本申请的一些实施例中,可以按照单一维度的特征信息分类。比如,时延敏感型场景属于一类,其余场景属于另外一类;再比如,卫星通信场景划分为一类,不支持卫星通信场景划分为另一类。其余维度的单一特征信息分类的方式与此类似,不再赘述。
在本申请的一些实施例中,可以按照多维度的复合特征信息分类。比如,同时满足时延敏感型场景且卫星通信场景划分为一类,其余场景分为另一类,等等。本申请对于基于至少两种特征信息进行终端分类的方式不进行限制,具体分类方式不再赘述。
(3)隐式配置方式3:网络为同时满足特殊终端类型以及特殊应用场景的终端配置专用的随机接入前导码根序列相关配置。
表3

Figure PCTCN2021082560-appb-000002
表3列出了随机接入前导码根序列相关配置的隐式方式3,其中,
a)网络设备如果仅配置了公共的随机接入前导码根序列相关配置,则所有应用场景下任何类型终端都只能使用公共的随机接入前导码根序列相关配置;
b)只有专用的随机接入前导码根序列相关配置在配置中出现且终端识别当前通信***属于特殊应用场景且自身属于特殊类型终端,终端设备才能使用专用的随机接入前导码根序列相关配置;
c)其他情况下,终端设备只能使用公共的随机接入前导码根序列相关配置。
另一方面,不同于隐式指示的方式,本申请实施例还可以采用显示指示的方式。如果随机接入前导码相关配置不仅包括随机接入前导码根序列相关配置,还包括对应的终端类型信息和/或应用场景信息,此时随机接入前导码根序列相关配置与终端类型和/或应用场景的关联关系(第一关联关系)是显式的,示例性地可包含如下三种配置方式:
(1)显示配置方式1:
表4
Figure PCTCN2021082560-appb-000003
参考表4所示的随机接入前导码根序列显式配置方式1,每一个专用的随机接入前导码根序列相关配置关联一个终端类型标识信息,终端根据自身的终端类型标识信息确定目标随机接入前导码根序列相关配置并将该配置用于随机接入过程;如果终端类型标识信息匹配但该类型对应的专用的随机接入前导码根序列相关配置没有被配置,则终端使用***公共的随机接入前导码根序列相关配置;如果终端类型标识信息与表4中配置的任何一种终端类型标识信息不匹配,则终端使用***公共的随机接入前导码根序列相关配置。
需要说明,不排除多个终端类型标识信息关联一个专用的随机接入前导码根序列相关配置的配置方式,本申请对这种配置方法不进行限制。

需要说明,不排除多个应用场景标识信息关联一个专用的随机接入前导码根序列相关配置的配置方式,本申请对这种配置方法不进行限制。
(3)显示配置方式3:
参考表6所示的随机接入前导码根序列显式配置方式3,每一个专用的随机接入前导码根序列相关配置关联一个应用场景标识信息以及至少一个终端类型标识信息,终端设备根据自身所处的应用场景以及自身终端类型确定目标随机接入前导码根序列相关配置并将该配置用于随机接入过程;只有终端设备所处的应用场景标识信息以及自身终端类型与表6中的至少一行的信息匹配,终端设备才能使用对应的专用的随机接入前导码根序列相关配置信息;否则,其他任何场景,终端只能使用公共的随机接入前导码根序列相关配置。

其中,关于随机接入前导码根序列相关配置与终端类型和/或应用场景之间的第一关联关系,可以为以下至少一者:一对一映射、一对多映射、多对多映射。此外,以上表4-6中的N均为大于等于1的正整数。
实施例3
在本申请的一种实施方式中,随机接入前导码相关配置中还包括:第一阈值配置信息,终端测得的当前小区测量结果需满足第一预定条件(第一预定条件与第一阈值有关),终端才能使用专用的随机接入前导码根序列相关配置,以下示例性地描述多种实现方式。
方式1:如果满足第一预定条件,允许终端设备使用实施例2中描述的专用的资源配置机制,来选择合适的资源,也就是允许终端设备按照表1-6中至少一者确定发起随机接入时使用的资源配置(有可能是专用的随机接入前导码根序列相关配置,也有可能是公共的随机接入前导码根序列相关配置)。
方式2:终端可先按照实施例2中描述的专用的资源配置机制确定发起随机接入时使用的资源配置,如果确定的是专用的随机接入前导码根序列相关配置,还需判断第一预设条件是否被满足,如果满足,则该专用的随机接入前导码根序列相关配置可用,如果不满足,则该专用的随机接入前导码根序列相关配置不可用,应使用公共的随机接入前导码根序列相关配置。
关于第一预定条件,可以为终端对当前服务小区或者目标小区的测量结果小于或等于第一阈值。当然,在某些实施例中,第一预定条件也可以为该测量结果大于或等于第一阈值。表7示意性地列出了一种基于第一阈值配置信息确定随机接入前导码根序列相关配置的方式。
表7
Figure PCTCN2021082560-appb-000006
需要说明,表7对应的资源选择方法是与实施例2中表1-6中的任何一种方法联合使用,可视为一种二级匹配逻辑,例如一种情况是,在满足表1-6中任意一种方法条件的同时满足表7的约束条件,终端才能选择专用的随机接入前导码根序列相关配置。
在本申请另一种实施方式中,随机接入前导码相关配置中还包括:第二阈值配置信息,在网络设备发送该第二阈值配置信息的同时,还需同时发送至少一组专用的随机接入前导码根序列相关配置和/或一组公共的随机接入前导码根序列相关配置,如果满足第二预定条件,终端使用专用的随机接入前导码根序列相关配置(例如在至少一组专用的随机接入前导码根序列相关配置中随机选择一组),如果不满足,终端使用该组公共的随机接入前导码根序列相关配置。
关于第二预定条件,可以为终端对当前服务小区或者目标小区的测量结果小于或等于第二阈值。当然,在某些实施例中,第二预定条件也可以为该测量结果大于或等于第二阈值。表8示意性地列出了一种基于第二阈值配置信息确定随机接入前导码根序列相关配置的方式。
如表8所示,网络侧配置了两套随机接入前导码根序列相关配置,在场景1下,终端选择使用专用的随机接入前导码根序列相关配置发起随机接入过程;场景2下,终端选择使用公共的随机接入前导码根序列相关配置发起随机接入过程。
表8
Figure PCTCN2021082560-appb-000007
需要说明,表7和表8中小区测量结果可能是小区级测量结果或者波束级测量结果,其中,测量结果可能包含RSRP/RSRQ/SINR三者之一或任意组合,也就是说,第一阈值(或第二阈值)信息可以针对单独的RSRP或RSRQ或SINR进行比较,此时第一阈值(或第二阈值)信息包含一个参数;也可针对RSRP/RSRQ/SINR中任两个或两个以上测量值进行比较,此时第一阈值(或第二阈值)信息包含的参数为两个或三个,本申请对此不做限制。
实施例4
在本实施例中,在前述的实施例2和/或实施例3的基础上,所述的随机接入前导码相关配置还可包括:与随机接入前导码根序列相关配置关联的MSGA PUSCH和/或RO资源配置,则随机接入前导码根序列相关配置可与MSGA PUSCH和/或RO资源配置进行关联,终端在选择目标随机接入前导码根序列相关配置后,可使用与目标随机接入前导码根序列相关配置关联的MSGA PUSCH和/或RO资源发起随机接入过程。
需要说明,前述的表1-8中任一种随机接入前导码根序列相关配置都可以关联至少一套MSGA PUSCH和/或RO资源配置,本申请对具体的关联方式不进行限制。
实施例5
在本实施例中,所述的第一配置信息用于基于非竞争的随机接入过程CFRA的资源配置,所述的第一配置信息包含至少一个专用RO资源对应的专用随机接入资源配置。本实施例对应实施例1中的思路2。
为更清楚地阐明本实施例的实现方式,以下先对相关已有规定的内容进行简要描述。
按照已有规定,CFRA的随机接入资源配置的基本思想是网络侧给终端配置一个独有的RO以及独有的preamble资源,相应地,相同的RO以及相同的preamble资源不会同时分配给其他终端使用,从而让网络侧快速识别当前终端。已有规定下,CFRA资源是网络侧通过专用信令发送给终端的,已有的CFRA随机接入资源配置形式如表9所示。
表9
Figure PCTCN2021082560-appb-000008
参考表9,NR***中RO的分配是基于SSB粒度进行的,一个SSB可以同时关联多个RO,在配置CFRA随机接入资源时,为了使一个SSB下对应的专用RO唯一,需通过表9中的专用RO位置标识信息(RO Mask index)进行指示,该指示信息对所有SSB通用,不论终端选择哪一个SSB发起随机接入,应该使用的专用RO在SSB下的位置编号是一样的,表10示意性示出了SSB与RO的关联关系。
表10
Figure PCTCN2021082560-appb-000009
表10以***配置两个SSB以及其中一个SSB关联3个RO为例进行说明,比如表9中专用RO位置标识信息取值为0,则终端在SSB1下只能使用RO1,在SSB2下只能使用RO4;再比如表9中专用RO位置标识信息取值为2,则终端在SSB1下只能使用RO3,在SSB2下只能使用RO6。
在满足CFRA资源使用条件时,终端根据当前准备发起随机接入过程的SSB编号,并结合表9,可确定本次CFRA应使用的专用RO以及preamble资源。其中,在配置每个SSB关联的专用MSGA PUSCH资源标识信息时,还可包括确定专用MSGA PUSCH资源。
本实施例可对已有方案进行增强,表11示意性示出本实施例的CFRA随机接入资源配置增强方式。
表11
Figure PCTCN2021082560-appb-000010
参考表11,网络设备配置给终端的专用RO资源不止一个,每个SSB关联的专用随机接入前导码可以是一个或者多个,每个SSB关联的专用MSGA PUSCH资源可以是一个或者多个。
如此,如果终端设备接收到网络设备配置的CFRA随机接入资源配置中包含的专用RO位置不止一个,则终端设备可能存在如下两种行为:
·行为1:终端认为网络设备允许终端在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试,两次相邻随机接入尝试可以使用相同的RO位置,也可以使用不同的RO位置以实现频分增益(不同的RO位置可通过表11中至少一个专用RO位置标识信息进行配置)。
·行为2:终端只能在确定前一次随机接入尝试失败(即终端在该随机接入尝试关联的RAR窗口内未接收到网络设备响应)后才能发起下一次随机接入尝试,每一次随机接入尝试可以使用相同的RO位置,也可以使用不同的RO位置实现频分增益(不同的RO位置通过表11中至少一个专用RO位置标识信息进行配置)。
需要说明,表11中专用RO位置标识信息与每个SSB关联的专用随机接入前导码preamble标识信息以及每个SSB关联的专用MSGA PUSCH资源标识信息之间可以是一一映射的关系,也就是,一个专用RO对应一个专用随机接入前导码preamble标识信息以及一个专用MSGA PUSCH资源标识信息;在本申请的某些实施例中,以上映射关系也可以是一对多映射,即一个专用RO可以对应多个专用随机接入前导码preamble标识信息以及对应多个专用MSGA PUSCH资源标识信息的配置形式。
进一步,本实施例还可采取为终端分配多套CFRA随机接入资源配置的增强方式,表12示意性示出了多套CFRA随机接入资源配置。
表12
Figure PCTCN2021082560-appb-000011
参考表12,其中示出了两套CFRA配置,在其他实施例中可为三套或更多CFRA配置。对于每一套CFRA配置,处理方式与表11类似地可包括两种终端设备行为,不同之处主要在于,每次随机接入尝试发起前,需要首先确定使用多套CFRA配置中的哪一套CFRA配置。选定使用的一套CFRA配置(例如表12中的第一套CFRA配置)后,对于在该套CFRA配置中的RO、每个SSB关联的专用随机接入前导码preamble资源、每个SSB关联的专用MSGA PUSCH资源的选择方式,与表11的处理过程 类似,这里不再赘述。
需要说明,表11或表12的方法可以与表1-8中的任一种方法组合使用,组合的方案对应于实施例1中的思路3,多种组合叠加的方案均可实现本申请实施例的目的。
实施例6
在本申请的一种实施方式中,所述的第一配置信息包含是否允许终端在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试的指示信息。
如果第一配置信息包含允许终端设备在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试的指示信息,则终端设备可以在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试;反之,则不允许终端设备在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试的指示信息,需确认本次随机接入尝试失败之后才能发起新的随机接入尝试。
需要说明,上述指示信息既可以适用于两步随机接入过程,也可以适用于四步随机接入过程,本申请对此不进行限制。
需要说明,上述指示信息既可以适用于CBRA过程,也可以适用于CFRA过程,本申请对此不进行限制。
需要说明,上述指示信息可以与前述实施例1-5中描述的方法(即表1-8以及表11-12对应的方法)中至少一种方法结合使用,例如,如果上述指示信息配置为允许,前述实施例1-5中描述的方法可激活使用;如果上述指示信息配置为不允许,前述实施例1-5中描述的方法不能激活使用。
实施例7
在前述的实施例1-6中至少一种方法的基础上,所述的第一配置信息可包含两次相邻随机接入尝试之间的最小时间间隔信息和/或一个RAR窗口内允许终端设备连续发起随机接入尝试的最大次数配置。如果第一配置信息中指示了最小时间间隔信息,则任意相邻两次随机接入尝试都必须满足该最小时间间隔后才能发送。对于允许或不允许终端在一次随机接入尝试对应的RAR窗口超时前发送新的随机接入尝试的两种场景下,该最小时间间隔信息均适用。
实施例8
在前述的实施例1-7中至少一种方法的基础上,所述的第一配置信息可包含有效时间配置信息。在所述有效时间配置信息规定的有效时间内,所述第一配置信息有效;在所述有效时间配置信息规定的有效时间外,所述第一配置信息失效。
以上通过多个实施例从不同角度描述了本申请实施例的具体设置和实现方式。与上述至少一个实施例的处理方法相对应地,本申请实施例还提供一种终端设备100,参考图5,其包括:
接收模块110,用于接收网络设备发送的第一配置信息,所述第一配置信息包括一组或多组随机接入资源配置,所述第一配置信息用于指示所述终端设备根据所述一组或多组随机接入资源配置发起随机接入过程。
