本申请涉及通信技术领域,尤其涉及一种资源配置的方法及装置。
物联网(Internet of Things,IoT)将互联网的用户端拓展到任何物品与物品之间,也就是任何物品之间均可以实现相互通信。IoT具有覆盖增强、支持大量低速率设备、设备低功耗等特殊需求。第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)通过了窄带物联网(Narrowband Internet of Things,NB-IoT)课题,试图通过NB-IoT满足上述的特殊需求。
在NB-IoT中,当终端设备有上行数据到达时,可通过随机接入过程申请上行资源,并使用获取的上行资源传输上行数据。但是,在这种方式中,终端设备需等到随机接入过程的第二条消息之后才能传输上行数据,导致终端设备的业务时延,同时也增加终端设备的功耗。
发明内容
本申请实施例提供资源配置方法及装置,降低终端设备的业务时延和功耗。
为达到上述目的,本申请实施例提供如下技术方案:
第一方面,本申请实施例提供一种资源配置方法,应用于网络设备,该方法包括:网络设备确定配置信息,向终端设备发送配置信息。
其中,配置信息用于指示终端设备的调度请求SR时频资源,配置信息包括第一配置信息和第二配置信息,第一配置信息用于指示SR时频资源的时域偏置,第二配置信息用于指示SR时频资源的持续时长,其中,时域偏置为SR时频资源的时域起始位置相对于随机接入时频资源的时域起始位置的偏置。
本申请实施例中,网络设备确定配置信息,并向终端设备发送配置信息,该配置信息用于指示终端设备的SR时频资源,一方面,使得终端设备占用配置信息所指示的SR时频资源向网络设备申请上行资源,用以终端设备传输上行数据,这里,终端设备可以通过发送SR向网络设备申请上行资源以用于发送上行数据,而无需通过执行随机接入过程的方式向网络设备申请上行资源,信令流程简化,从而减少终端设备的功耗和时延。
另一方面,由于配置信息可指示SR时频资源的时域偏置和持续时长,从而可灵活的将随机接入时频资源划分为对应不同时域偏置和持续时长的至少一个SR时频资源,也就是,随机接入时频资源可被至少一个终端设备使用,进而提升了SR容量。
第二方面,本申请实施例提供一种资源配置方法,应用于终端设备,该方法包括:终端设备接收配置信息,后续,当存在上行数据且无可用上行资源的情况下,终端设备占用配置信息所指示的SR时频资源向网络设备发送SR。
其中,配置信息用于指示终端设备的调度请求SR时频资源,配置信息包括第一配置信息和第二配置信息,第一配置信息用于指示SR时频资源的时域偏置,第二配 置信息用于指示SR时频资源的持续时长,其中,时域偏置为SR时频资源的时域起始位置相对于随机接入时频资源的时域起始位置的偏置。
第三方面,本申请实施例提供一种资源配置方法,应用于网络设备,该方法包括:网络设备确定配置信息,向终端设备发送配置信息。
其中,配置信息包括终端设备的SR时频资源位图,位图中的比特取值用于指示对应的符号组。
第四方面,本申请实施例提供一种资源配置方法,应用于终端设备,该方法包括:终端设备接收配置信息,后续,当存在上行数据且无可用上行资源的情况下,终端设备占用配置信息所指示的SR时频资源向网络设备发送SR。
其中,配置信息包括终端设备的SR时频资源位图,位图中的比特取值用于指示对应的符号组。
以下结合上述第一方面、第二方面、第三方面、第四方面,对可能的设计方式进行说明:
在一种可能的设计中,随机接入资源为网络设备通过***消息配置的可用于随机接入前导码传输的时频资源,其中随机接入资源包括基于竞争的随机接入资源,SR时频资源为随机接入时频资源的子集;或者,随机接入资源为网络设备通过***消息配置的可用于随机接入前导码传输的时频资源,其中随机接入资源包括基于竞争的随机接入资源,SR时频资源为随机接入的时频资源中除去基于竞争的随机接入时频资源以外的时频资源的子集。
一方面,当窄带物理上行共享信道(Narrowband Physical Uplink Shared CHannel,NPUSCH)传输与NPRACH传输冲突时,NPUSCH传输会推迟。因此,若将部分NPRACH资源配置为SR时频资源,则NPUSCH传输与SR传输冲突时可以沿用上述的NPUSCH推迟传输机制,不会对NPUSCH的调度增加限制。另一方面,由于非竞争时频资源是通过窄带物理下行控制信道(Narrowband Physical Downlink Control Channel,NPDCCH)调度分配的,所以基站可通过调度避免SR和NPRACH的冲突。
在一种可能的设计中,SR时频资源的频域资源与随机接入时频资源的频域资源相同。
在一种可能的设计中,持续时长为第一时间长度的整数倍,其中第一时间长度为随机接入前导码单次传输的时长;或者,持续时长为随机接入前导码的一个符号组时长的整数倍。
在一种可能的设计中,时域偏置为第一时间长度的整数倍,其中第一时间长度为随机接入前导码单次传输的时长;或者,持续时长为随机接入前导码的一个符号组时长的整数倍。
通过上述的SR时频资源指示方式,可灵活的配置每一终端设备的SR时频资源的时长,进而灵活的将随机接入时频资源分配给多终端设备使用,增加SR容量。
在一种可能的设计中,配置信息还包括载波配置信息、子载波配置信息、增强覆盖等级配置信息,其中,载波配置信息用于指示SR时频资源占用的载波,子载波配置信息用于指示SR时频资源占用的子载波,增强覆盖等级配置信息用于指示SR时频资源的增强覆盖等级的信息。
在一种可能的设计中,子载波配置信息所指示的子载波索引处于第一数值区间的情况下,用于指示终端设备传输SR所采用的格式为格式2;子载波配置信息所指示的子载波索引处于第二数值区间的情况下,用于指示终端设备传输SR所采用的格式为格式0或格式1。
在一种可能的设计中,配置信息还包括格式配置信息,其中,格式配置信息为格式索引、循环前缀CP长度、子载波带宽中的一种;格式配置信息用于终端设备确定传输SR所采用的格式。
采用上述指示传输SR所采用格式的方式,终端设备可确定采用哪种格式子载波传输SR,从而站点在频域上使用相应格式的子载波传输SR。

以网络设备为基站为例,终端设备通过随机接入过程与基站建立连接并取得上行同步。基站可为终端设备配置随机接入时频资源,终端设备发起随机接入之前,需获取基站下发的随机接入时频资源,以便于后续终端设备占用随机接入时频资源发起随机接入。其中,随机接入过程包括终端设备向基站发送随机接入前导码(为便于描述,下文称之为前导码)的流程。通常,在基站为终端设备配置随机接入时频资源时,可为终端设备配置前导码的重复次数。那么,对于某一终端来说,随机接入时频资源包括在该次随机接入过程中传输多次前导码使用的时频资源之和,参见图3,对于终端设备1来说,在某一次随机接入过程中的时频资源包括第一次重复传输(图3中的重复次数#1)前导码时使用的时频资源、第二次重复传输前导码时使用的时频资源、第三次重复传输前导码时使用的时频资源与第四次重复传输前导码时使用的时频资源之和。
在各种通信***中,为避免资源浪费,如果终端设备设备没有上行数据需要传输,网络设备就不会为该终端设备设备分配上行资源。当终端设备设备有上行资源需要传输时,首先应该告知网络设备终端设备设备需要传输上行资源,请求网络设备为该终端设备设备分配上行资源。
在现有的NB-IoT***中,当终端设备需要向网络设备发送上行数据时,需要重新发起随机接入,之后再发送上行数据。现有技术中,终端设备需要等待较长时间、执行较多操作后才能发送上行数据,这会增加终端设备的功耗和时延。并且,当有多个终端设备发生接入冲突时,终端设备可能会发生退避甚至失败,进一步加剧终端设 备的功耗和时延。
本申请基于上述问题,提出一种资源配置方法,由网络设备预先向终端设备发送配置信息,当终端设备有上行数据需要发送时,终端设备在配置信息所指示的特定资源上向网络设备发送SR,即告知网络设备终端设备需要发送数据,进而直接发送上行数据,而不需要执行随机接入过程,从而减少终端设备的功耗和时延。
本申请实施例提供一种资源配置方法,如图4所示,该方法包括如下步骤:
S401、网络设备确定配置信息,配置信息用于指示终端设备的调度请求SR时频资源。
其中,配置信息包括第一配置信息和第二配置信息,第一配置信息用于指示SR时频资源的时域偏置,第二配置信息用于指示SR时频资源的持续时长,其中,时域偏置为SR时频资源的时域起始位置相对于随机接入时频资源的时域起始位置的偏置。
S402、网络设备向终端设备发送配置信息。
S403、终端设备接收配置信息。
S404、终端设备在配置信息所指示的SR时频资源上发送SR。
需要说明的是配置信息可以承载在无线链路控制(Radio Resource Control,RRC)信令,媒体接入控制(Media Access Control,MAC)控制元素(Control Element,CE)或者物理层信令,例如下行控制信息(Downlink Control Information,DCI)中。
需要说明的是,可选地,终端设备在接收网络设备发送的配置信息后,并不立即向网络设备发送SR,而是在有上行数据到达终端设备且终端设备没有可用的上行资源的情况下,向网络设备发送SR,以请求网络设备为终端设备分配可用的上行资源。
下文主要以网络设备为基站为例来说明本申请实施例的技术方案,这里统一说明,下文不再赘述。
需要说明的是,上文所指随机接入的时频资源为网络设备通过***消息配置的可用于随机接入前导码传输的时频资源,其中随机接入资源包括基于竞争的随机接入资源,SR时频资源为随机接入时频资源的子集,或者,SR时频资源为随机接入的时频资源中除去基于竞争的随机接入时频资源以外的时频资源的子集。需要说明的是,当窄带物理上行共享信道(Narrowband Physical Uplink Shared CHannel,NPUSCH)传输与NPRACH传输冲突时,NPUSCH传输会推迟。因此,若将部分NPRACH资源配置为SR时频资源,则NPUSCH传输与SR传输冲突时可以沿用上述的NPUSCH推迟传输机制,不会对NPUSCH的调度增加限制。为便于描述,本文中将随机接入的时频资源中除去基于竞争的随机接入时频资源以外的时频资源称为非竞争时频资源。这样,由于非竞争时频资源是通过窄带物理下行控制信道(Narrowband Physical Downlink Control Channel,NPDCCH)调度分配的,所以基站可通过调度避免SR和NPRACH的冲突。
另外,可选的,SR时频资源的频域资源与随机接入时频资源的频域资源相同。如图5所示,随机接入时频资源的频域资源为序号#0至#11的子载波,则配置的SR时频资源的频域资源也为序号#0至#11的子载波。
本申请实施例中,网络设备确定配置信息,并向终端设备发送配置信息,该配置信息用于指示终端设备的SR时频资源,一方面,使得终端设备占用配置信息所指示的SR时频资源向网络设备申请上行资源,用以终端设备传输上行数据,这里,终端设备 可以通过发送SR向网络设备申请上行资源以用于发送上行数据,而无需通过执行随机接入过程的方式向网络设备申请上行资源,信令流程简化,从而减少终端设备的功耗和时延。另一方面,由于配置信息可指示SR时频资源的时域偏置和持续时长,这种情况下网络设备可以灵活的将随机接入时频资源划分为对应不同时域偏置和持续时长的至少一个SR时频资源,也就是,随机接入时频资源可被至少一个终端设备使用,进而提升了SR容量。
图5示出了随机接入时频资源被3个终端设备复用的情况,随机接入的时频资源包括前导码重复传输四次使用的时频资源之和。其中,用于第一次重复传输前导码的时频资源被配置为终端设备1的SR时频资源,用于第二次重复传输前导码的时频资源被配置为终端设备2的SR时频资源,用于第三、四次重复传输前导码的时频资源被配置为终端设备3的SR时频资源。
当然,由于可将随机接入时频资源分配给多个终端使用,可以减少闲置的随机接入时频资源,提高随机接入时频资源的利用率。
其中,上述步骤S401-S404中基站的动作可以由图2所示的通信设备200中的处理器201调用存储器203中存储的应用程序代码来执行,本申请实施例对此不作任何限制。
其中,上述步骤S403与S404中终端设备的动作可以由图2所示的通信设备200中的处理器201调用存储器203中存储的应用程序代码来执行,本申请实施例对此不作任何限制。
可选的,上述时域偏置为第一时间长度的整数倍,其中第一时间长度为随机接入前导码单次传输的时长。
可选的,持续时长为第一时间长度的整数倍,或者,持续时长为随机接入前导码的一个符号组时长的整数倍。
其中,随机接入前导码由若干个符号组组成,每个符号组包括至少一个符号和循环前缀(Cyclic Prefix,CP)。其中,至少一个符号的总时长为Tseq,CP的时长为Tcp。在不同格式的随机接入前导码中,符号组的个数可能不同,符号组的结构可能不同,即符号组中符号的数目不同、和/或CP长度(在时域上)不同、和/或符号的长度(在时域上)不同。这里,随机接入前导码格式包括但不限于格式0、格式1、格式2。示例性的,在频分双工(Frequency Division Duplex,FDD)NB-IoT中,随机接入前导码的格式包括格式0,格式1和格式2,上述各种格式的对比数据如下表1所示。其中Ts为时间单元,作为一种可能的取值,Ts=1/(15000*2048)。
表1
格式 | Tcp | Tseq | 每个符号组中符号数 | 子载波带宽 |
格式0 | 2048Ts | 8192Ts | 5 | 3.75kHz |
格式1 | 8192Ts | 8192Ts | 5 | 3.75kHz |
格式2 | 24576Ts | 24576Ts | 3 | 1.25kHz |
以持续时长为第一时间长度的整数倍,且时域偏置为第一时间长度的整数倍为例, 如图5所示,假定以子载波带宽为3.75kHz的随机接入前导码为例,随机接入前导码单次传输的时长为T,前导码重复传输次数为4,且随机接入时频资源的时域起始位置为0。终端设备1的配置信息包括:第一配置信息和第二配置信息,其中,第一配置信息指示终端设备1的SR时域资源的时域偏置为0(与随机接入时频资源的时域起始位置重合),第二配置信息用于指示终端设备1的SR时频资源的持续时长为T。终端设备2的配置信息中:第一配置信息指示终端设备2的SR时域资源的时域偏置为T,即相对于随机接入时频资源的时域起始位置(0)的偏置为T,第二配置信息用于指示终端设备2的SR时频资源的持续时长为T。终端设备3的配置信息中:第一配置信息指示终端设备3的SR时域资源的时域偏置为2T,第二配置信息用于指示终端设备3的SR时频资源的持续时长为2T。
当然,上述的时域偏置还可以是SR时频资源的时域起始位置相对于随机接入时频资源的时域结束位置的偏置。本申请实施例对此不做限制。
以持续时长为随机接入前导码的一个符号组时长的整数倍且时域偏置非第一时间长度的整数倍为例,如图6中(a)所示,终端设备1的配置信息中:第一配置信息指示终端设备1的SR时域资源的时域偏置为0,第二配置信息用于指示终端设备1的SR时频资源的持续时长为
终端设备2的配置信息中:第一配置信息指示终端设备2的SR时域资源的时域偏置为
第二配置信息用于指示终端设备2的SR时频资源的持续时长为
终端设备3的配置信息中:第一配置信息指示终端设备3的SR时域资源的时域偏置为
第二配置信息用于指示终端设备3的SR时频资源的持续时长为
需要说明的是,每一终端设备的SR时频资源的时域偏置与持续时长并不局限于上述举例的情况,可根据实际情况配置每一终端设备的SR时频资源的时域偏置与持续时长,本申请实施例对此不进行限制。
可选的,在不同版本(Release)的通信标准中,SR传输一次占用的符号组数目可能不同,则通过第一配置信息和第二配置信息指示的SR时频资源在时域上可以是连续的或者非连续的。连续是指某一终端设备可在连续的时段内传输一次SR,非连续是指该终端设备可使用数个跨时段的符号组传输一次SR。示例性的,在SR传输一次占用4个符号组的情况下,若终端设备的SR时频资源在时域上包括至少4个且连续的符号组,则终端设备的SR时频资源在时域上是连续的。如图5中,终端设备1的SR时频资源在时域上包括4个且连续的符号组,可用于传输一次SR,那么,终端设备1的SR时频资源为连续资源。若终端设备的SR时频资源在时域上不包括至少4个且连续的符号组,则终端设备的SR时频资源在时域上是非连续的。如图6中(b)所示,终端设备1的第一SR时频资源在时域上包括3个且连续的符号组,不足以传输一次SR,那么,为了使终端1至少传输一次SR,网络设备可配置终端1的第二SR时频资源。参见图6中(b),第二SR时频资源对应的配置信息中:第一配置信息指示该第二SR时频资源的时域偏置为
第二配置信息指示该第二SR时频资源持续时长为
如此,终端1的第一SR时频资源和第二SR时频资源在时域并不连续,但是,这两个SR时频资源可跨时段支持终端1的SR传输。
当然,上述仅以SR传输一次占用4个符号组为例进行说明,在实际应用场景中,SR传输一次在时域上占用符号组的数目可能不同,本申请实施例对此不进行限制。
通过上述的SR时频资源指示方式,可灵活的配置每一终端设备的SR时频资源的时长,不同终端设备的SR时频资源的时长可以相同或者不同,本申请实施例对此不进行限制。
另外,上述图5、图6中(a)、图6中(b)并未示出前导码每次传输之间的时间间隔,可以理解的是,在单次随机接入过程中,终端设备的数次传输前导码之间可能存在时间间隔。参见图7,在单次随机接入过程中,第一次传输前导码与第二次传输前导码之间的时间间隔为
在这种情况下,终端设备1的配置信息中:第一配置信息指示终端设备1的SR时域资源的时域偏置为0,第二配置信息用于指示终端设备1的SR时频资源的持续时长为T。终端设备2的配置信息中:第一配置信息指示终端设备2的SR时域资源的时域偏置为
第二配置信息用于指示终端设备2的SR时频资源的持续时长为T。也就是,网络设备在确定终端设备的SR时频资源的时域偏置和持续时长时,需参考两次前导码传输之间的时间间隔。
基于该第一配置信息和第二配置信息,相应的终端设备可获知自身SR时频资源在单次随机接入时频资源中的时域位置。
在本申请的另一些实施例中,还提供另一种资源配置的方法,该方法的流程与图4流程中的步骤相同,因此,本实施例的方法流程图可参考图4,该实施例与图4实施例的区别是:本实施例中的配置信息与图4对应实施例中的配置信息不同。
其中,在本实施例中,配置信息为终端设备的SR时频资源位图,位图中的比特取值用于指示对应的符号组。
示例性的,位图可以以前导码单次传输的时长为粒度。以子载波带宽为3.75kHz的随机接入前导码为例,一个前导码单次传输时长为T,则位图中的比特取值用于指示在时长T内对应的符号组。
可选的,位图中比特的位数为一个随机接入前导码包含的符号组数目。例如,在Release 13和Release 14中,一个前导码包含4个符号组,相应的,在配置SR时频资源时,位图中比特位数为4。可选的,若某一终端设备的位图中的第N个比特取值为1,则指示第N个符号组配置给该终端设备,若某一终端设备的位图中的第M个比特取值为0,则指示第M个符号组未被配置给该终端设备。或者,若某一终端设备的位图中的第N个比特取值为0,则指示第N个符号组配置给该终端设备,若某一终端设备的位图中的第M个比特取值为1,则指示第M个符号组未被配置给该终端设备,对于位图中的比特取值具体指示的内容,本申请实施例不做限制。
参见图8中(a),假定终端设备的位图中的第N个比特取值为1,指示第N个符号组被配置给终端设备。则终端设备1的配置信息所包含的位图为1000,终端设备2的配置信息所包含的位图为0100,终端设备3的配置信息所包含的位图为0010,终端设备4的配置信息所包含的位图为0001。这里,位图表示在每一个前导码传输时长T 中,一个前导码中的第一个符号组被配置给终端设备1,第二个符号组被配置给终端设备2,第三个符号组被配置给终端设备3,第四个符号组被配置给终端设备4。进而,在每一前导码传输时长内,终端设备1占用该前导码传输时长内第一个符号组传输SR,终端设备2占用第二个符号组传输SR,终端设备3占用第三个符号组传输SR,终端设备4占用第四个符号组传输SR。
可选的,SR重复传输的次数可由单次随机接入中前导码重复传输次数与位图长度确定。示例性的,参考图8中(a),若单次随机接入中前导码重复传输次数为4,且位图长度为4比特位(说明一个前导码包含4个符号组),则SR重复次数为前导码重复次数(4)除以位图长度(4)后得到的数值,即1,也就是,如图8中(a)终端设备1的SR重复传输次数为1、终端设备2的SR重复传输次数为1、终端设备3的SR重复传输次数为1,即该单次随机接入时频资源可复用4个终端设备,使得4个终端设备可分别传输一次SR。
当然,在每次前导码的传输时长T内,终端设备1可占用不仅一个符号组。参见图8中(b),在每一前导码的传输时长T内,终端设备1可占用第一、三个符号组。此时,终端设备1的位图为1010,终端设备2的位图为0100,终端设备4的位图为0001。
在位图指示SR时频资源位置的方式中,每一终端设备的SR时频资源可以是不连续的。例如,假定传输一次SR在时域上需占用4个符号组,如图8中(b)所示,终端可占用前导码第一次传输时长T中的第一个符号组、第三个符号组以及占用前导码第二次传输时长T中的第一个符号组、第三个符号组,用以传输一次SR。这里,终端设备占用的符号组在时域非连续。
在位图指示SR时频资源位置的方式中,每一终端设备的SR时频资源也可以是连续的。SR重复传输次数或者持续时间可以通过单次随机接入前导码重复次数和位图长度确定,位图长度表示位图中包含的比特数。例如单次随机接入前导码重复传输次数为R,位图长度为L,则SR重复传输次数为R/L。或者单次随机接入前导码重复传输次数为R,位图长度为L,一个前导码单次传输时长为T,则SR传输持续时长为RT/L。在该示例中单次随机接入前导码重复传输R次的资源分成L部分,位图的比特位与各部分资源一一对应。比特位为1表示终端设备可以使用对应部分资源传输SR,比特位为0表示终端设备不可以使用对应部分资源传输SR,或者比特位为0表示终端设备可以使用对应部分资源传输SR,比特位为1表示终端设备不可以使用对应部分资源传输SR。以具体数值为例,单次随机接入前导码重复传输次数为R=4,位图长度为L=2,则SR重复传输次数为R/L=4/2=2。在该示例中,单次随机接入前导码重复传输4次的资源分成2部分,配置给终端设备1的位图为10,表示终端设备1可以使用第一部分资源发送SR,即终端设备1可以使用随机接入前导码第一次和第二次重复传输的资源发送SR,配置给终端设备2的位图为01,表示终端设备2可以使用第二部分资源发送SR,即终端设备2可以使用随机接入前导码第三次和第四次重复传输的资源发送SR。
可选的,配置信息还包括载波配置信息、子载波配置信息、增强覆盖等级配置信息,其中,载波配置信息用于指示SR时频资源占用的载波,子载波配置信息用于指 示SR时频资源占用的子载波,增强覆盖等级配置信息用于指示SR时频资源的增强覆盖等级的信息,增强覆盖等级的信息包括增强覆盖等级索引信息或前导码重复传输次数。
需要说明的是,在NB-IoT中,一个载波的带宽为180kHz,通常一个前导码占用一个子载波。在不同版本的通信标准中,NB-IoT子载波的带宽不同。例如,在版本13和版本14中,NB-IoT子载波带宽均为3.75kHz,在版本15中,NB-IoT子载波带宽为1.25kHz。因此,在版本13和版本14中,一个NB-IoT载波包含48个子载波,即一个NB-IoT载波可支持配置48个前导码。在版本15中,一个NB-IoT载波包含144个子载波。
其中,增强覆盖等级反映了终端设备与网络设备之间距离的远近,或者,反映小区覆盖质量(即链路的信号质量),其在时域上与随机接入过程中前导码的重复传输次数相关。通常,前导码重复传输次数越大,增强覆盖等级越高。以版本13为例,增强覆盖等级分为三种,等级0、等级1、等级2,等级0的重复次数为2,等级1的重复次数为8,等级2的重复次数为32。
需要说明的是终端设备在获取配置信息之前,会通过***消息获取随机接入资源配置指示信息。终端设备需要上文提及的配置信息和随机接入资源配置指示信息在确定载波位置,在指定载波内的子载波位置,以及增强覆盖等级时需要结合。例如在随机接入资源配置指示信息中包括可用于随机接入的载波配置指示信息,在载波配置指示信息中包括载波索引,终端设备根据获取到的载波索引和载波配置指示信息确定可用于SR传输的载波位置;在随机接入资源配置指示信息中包括上述指定载波内可用于随机接入的子载波配置指示信息,在配置信息中包括子载波索引,终端设备根据获取到的子载波索引和子载波配置指示信息确定可用于SR传输的子载波位置;在随机接入资源配置指示信息中包括1至3个覆盖等级的资源配置指示信息,每个覆盖等级的资源配置指示信息中包括随机接入前导码起始位置,周期,重复次数等,在配置信息中包括增强覆盖等级索引信息或前导码重复传输次数,终端设备根据获取到的增强覆盖等级索引信息或前导码重复传输次数和1至3个覆盖等级的资源配置指示信息确定可用于SR传输的随机接入资源对应的起始位置,周期和重复次数。
如图3所示,通过配置信息,终端获知需占用的载波为第2个NB-IoT载波,在频域上占用的子载波为图3所示的序号为#0至#11的子载波,且增强覆盖等级配置信息指示前导码的重复次数为4次。
本申请实施例还提供如下至少三种确定传输SR所采用格式的方式:
方式1:可利用子载波索引的数值大小区分子载波的格式。
网络设备向终端发送配置信息,终端接收到该配置信息后,若终端确定配置信息中包含子载波配置信息所指示的子载波索引处于第一数值区间的情况下,则终端传输SR采用第一格式0或格式1传输SR。若终端确定配置信息包含的子载波配置信息所指示的子载波索引处于第二数值区间的情况下,则后续流程中终端采用格式2传输SR。第一格式可以为格式2,第二格式可以为格式0或格式1。示例性的,如表2,当终端接收的配置信息中的子载波配置信息指示的子载波索引处于0至47范围内时,终端采用3.75kHz的子载波传输SR,即终端采用格式0或者格式1的子载波配置SR时频资 源,用以传输SR,当终端的子载波索引为48至191,终端采用格式2的子载波配置SR时频资源。或者,如表3,当子载波索引为0至143,终端采用格式2的子载波配置SR时频资源,当子载波索引为144至191,终端采用格式0或者格式1的子载波配置SR时频资源。当然,也可以定义处于其他数值区间的子载波索引对应格式2,具体哪个数值区间的子载波索引对应哪种格式,本申请实施例不做限制。
表2
表3
可以理解的是,若用比特指示上述子载波索引,则0至191这192个状态需8比特位指示。如此,信令开销较少。
方式2:上述子载波索引还可以按照同一粒度进行指示,通过使用同一粒度的子载波索引指示子载波所属的格式。
网络设备向终端发送配置信息,终端接收该配置信息,配置信息中包括子载波配置信息,子载波配置信息用于指示子载波的索引。
示例性的,可将1.25kHz子载波索引作为粒度,来指示3.75kHz子载波。如图9所示,以配置带宽为90kHz的子载波为例进行说明。其中,0至11的带宽为3.75kHz的子载波共占45kHz,0至35的带宽为1.25kHz的子载波共占45kHz。这里,子载波索引按照1.25kHz子载波的索引设置,也就是,一个3.75kHz子载波对应3个子载波索引号,一个1.25kHz子载波对应1个子载波索引号,如图9中,实际索引号为0的3.75kHz子载波可对应0、1、2这三个子载波索引号,实际索引号为34的1.25kHz子载波对应70这一子载波索引号。网络设备确定的配置信息中子载波配置信息所指示的子载波索引号为图9所示0至71。终端在接收到配置信息后,根据子载波配置信息所指示的子载波索引号(0至71),确定传输SR所采用的格式。
作为一种可能的实现方式,若终端确定子载波配置信息指示子载波索引的数值范围在0至35之间,则终端获知需采用格式0或格式1的子载波,若子载波索引的数值范围在36至71之间,则终端采用格式2的子载波传输SR。
可见,在90kHz带宽范围内,需设置的子载波索引数目为72,相应的,在180kHz带宽范围内,需设置的子载波索引数目为144。如此,指示144个状态与指示192个状态相比,可以节约部分信令开销。
当然,本申请实施例并不局限于上述图9所示的指示方式,只要是按照1.25kHz子载波索引的方式统一设置全部子载波的索引即可。
可选的,考虑到格式2的1.25kHz与格式0或1的3.75kHz的兼容性,应该保证格式2的1.25kHz与格式1或0的3.75kHz的资源配置不能重叠。基于此,在本申请实施例中,可以采用频分方式,将1.25kHz的子载波和3.75kHz的子载波在频域上进行区分。
同理,还可以通过不同的增强覆盖等级在时域上将1.25kHz子载波对应的SR时域资源和3.75kHz子载波对应的SR时域资源进行区分。参见表4:
表4
如表3所示,不同格式下,同一增强覆盖等级的前导码重复次数不同,同一格式下,不同增强覆盖等级的前导码重复次数也不同。因此,可从时域上将不同格式的SR时频资源加以区分。
方式3:终端的配置信息还可包括格式配置信息,格式配置信息用于确定终端传输SR所采用的的格式。
网络设备向终端发送配置信息,该配置信息中包括格式配置信息。其中,格式配置信息为格式索引、CP长度、子载波带宽中的一种。终端根据配置信息中的格式配置信息确定传输SR所采用的格式。
若终端接收的配置信息中的格式配置信息为格式索引,终端通过该格式索引获知传输SR采用的格式,示例性的,格式索引可采用2bit来指示终端传输SR所采用的格式。具体的,2bit格式索引可以为00、01、10、11中的任意三个。例如,格式索引为00、01、10,其中,00表示终端采用格式0或1的子载波传输SR,01也指示终端采用格式0或格式1子载波传输SR,10表示终端采用格式2的子载波传输SR。或者,可以用00指示终端采用格式2子载波传输SR,01指示终端采用格式0子载波传输SR,10指示终端采用格式1子载波传输SR。当然,也可以用00指示终端采用格式2子载波传输SR,01指示终端采用格式0或1子载波传输SR,10指示终端采用格式0或1子载波传输SR。本申请实施例对此不做限制。
或者,格式索引可采用1bit来指示终端传输SR所采用的格式。具体的,1bit格式索引可以为0或1,0指示终端采用格式2子载波传输SR,1指示终端采用格式0或1的子载波传输SR。或者,也可以0指示终端采用格式1或0的子载波传输SR,1指示终端采用格式2的子载波传输SR,本申请实施例对此不做限制。即同样的1bit(0)可用于指示不同内容(例如比特0可指示格式0,也可指示格式2),同样的2bit也可指示不同内容(例如比特00可指示格式0,也可指示格式2),这可拓展到N比特用于指示不同内容,这需要根据实际应用配置,本申请实施例不对此进行限制,且在此处进行同一说明,下文不再赘述。
若格式配置信息为CP长度,示例性的,当CP长度为66.7时,采用格式0子载波传输SR,当CP长度为266.7时,采用格式1子载波传输SR,当CP长度为800时,采用格式2子载波传输SR。
这里,同样可以采用bit来指示CP长度。可选的,采用2bit来指示CP长度,2bit可为00、01、10、11中的任意三个,例如,采用00、01、11这三个2bit。其中,00可指示CP长度为66.7,即指示终端采用格式0子载波传输SR,01可指示CP长度为266.7,即可指示终端采用格式1子载波传输SR,11可指示CP长度为800,即可指示终端采用格式2子载波传输SR。
若格式配置信息为子载波带宽,示例性的,采用1bit指示子载波带宽。例如,0指示3.75kHz,即指示终端采用格式2传输SR,1指示1.25kHz,即指示终端采用格式0或1传输SR。
当然,格式配置信息还可以是每一格式的其他特性信息,例如,可以是格式2中一个前导码占用的符号组数目信息,可以是格式2中一个前导码占用符号组的总时长信息,本申请在这里不再一一列举。
与现有技术相比,本申请实施例中,一方面,本申请实施例引入了格式2的子载波,可将格式2的子载波用于传输SR。由于格式2的子载波带宽比较窄,在相同的频域资源内,比如180kHz,子载波数量多,这意味着可支持更多数目的前导码传输,也 就是,能支持更多的SR传输。因此使用部分格式2的子载波,相比只使用格式0或者格式1的子载波,可以提升SR容量。另一方面,可区分出终端采用哪种格式子载波传输SR,从而在频域上使用相应格式的子载波传输SR。
需要说明的是,本文提及的格式为随机接入前导码的格式,于格式0、格式1、格式2。
其中,不同格式的随机接入前导码中,符号组的个数可能不同,符号组的结构也可能不同。关于格式0、格式1、格式2的具体符号组构成等描述可参见上文描述,这里不再赘述。
可选的,本文中SR的信号格式和随机接入前导码的格式相同,或者SR的符号组的信号格式和随机接入前导码的信号格式相同。SR在频域上的跳频规则和随机接入前导码的跳频规则相同。
另外,上述确定传输SR所采用格式的指示方式可应用在现有场景,即应用单次随机接入时频资源仅被一个终端占用的场景。还可以应用在多终端复用场景,即本申请上述实施例的单次随机接入时频资源可被多终端复用的场景,本申请实施例对此不加以限制。
在本申请的另一些实施例中,可以为SR传输提供功率控制。
可选的,采用随机接入成功时前导码对应的目标接收功率进行第一次SR传输,并基于路损补偿的方式确定最终的SR传输功率。其中,路损补偿的流程可参见现有技术,这里不再赘述。
之后,在第N次传输SR时,在上述目标接收功率的基础上,采用功率攀升的方式提高SR传输功率。可选的,可设置功率攀升步长,每次SR传输将目标接收功率提高功率攀升步长,例如,在第二次SR传输时,在目标接收功率的基础上增加一个功率攀升步长,得到第二次SR的传输功率,在第三次SR传输时,在第二次SR传输功率的基础上增加一个功率攀升步长,得到第三次SR的传输功率,以此类推,以逐步提高SR传输的有效性和可靠性。
这样,在进行第一次SR传输时,不再使用随机接入初始时的接收功率,进而在后续数次SR传输中,是以一个较大的目标接收功率开始向上攀升功率,功率攀升的效果较为显著,节约终端用于功率攀升的时间,降低时延,也降低终端用于功率攀升的功耗。
当然,本申请实施例提供的SR传输功率控制的方法,可应用于现有场景,或者,还可以应用于多终端复用场景。现有场景和多终端复用场景的描述可参见上文,这里不再赘述。
需要强调的是,本文中提及的各个信息的名称仅仅是其中的一种示例,在实际应用中,每一信息还可能是其他的名称,本申请实施例对此不做限制。
