Description

触发方法及相关装置
技术领域
本发明涉及通信技术领域, 尤其是涉及一种触发方法及相关装置。
背景技术
随着物联网的发展, 机器对机器(M2M, machine-to-machine )设备的数 量也随之增加。 标准化组织第三代合作伙伴计划 (3GPP , 3rd Generation Partnership Project )专门成立项目组, "Provision of low-cost MTC UEs based on LTE", 研究基于长期演进(LTE, Long Term Evolution )低成本的机器类型通 信(MTC, machine type communication )终端。 基于 LTE的氐成本 MTC终端的 研究主要考虑针对 MTC设备的引入而需要对 LTE网络及空中接口进行的增强 或优化, 其中覆盖问题是运营商关心的关键问题之一。考虑到成本以及频谱因 素, 运营商提出了新的需求: LTE系统在给 MTC终端提供服务时, 相对于现在 的 LTE系统, 其覆盖需要有 20dB的增强。
针对运营商提出的 20dB的 LTE系统覆盖增强的需求,现有技术釆用重复的 方式对 LTE的物理信道进行增强。 以覆盖增强的物理下行控制信道(PDCCH, Physical Downlink Control Channel )或覆盖增强的增强型物理下行控制信道 ( ePDCCH, Enhanced Physical Downlink Control Channel )为例, 一种覆盖增 强方法是基站将 PDCCH或 ePDCCH承载的下行控制信息 ( DCI , Downlink Control Information )在连续的 N( N为正整数 )个子帧内的控制信道单元 ( CCE, Control Channel Element )或增强型控制信道单元(eCCE, Enhanced Control Channel Element ) 中重复发送, MTC UE将这 N个子帧接收到的 CCE或 eCCE的 信息内容合并起来进行检测, 从而提高了检测性能。 这种覆盖增强的 PDCCH 或 ePDCCH检测需要 UE先提取覆盖增强的 PDCCH或 ePDCCH映射在 N个子帧 内的 CCE或 eCCE信息, 然后进行 N个子帧内 CCE或 eCCE信息内容合并, 再进 行译码。
由此可知, UE只有对 PDCCH或 ePDCCH检测后才能知道是否有自己的 DCI, 即 UE需要在每一个子帧进行 PDCCH或 ePDCCH的检测, 或者在覆盖 增强的 PDCCH或 ePDCCH所在的子帧检测覆盖增强的 PDCCH或 ePDCCH, 从而才能获知基站是否对该 UE发送了 DCI。 但由于基站可能并没有对所有 UE都发送 DCI, 因此在一个子帧, 或者覆盖增强的 PDCCH或 ePDCCH所在 的子帧中并不总是有该 UE的 DCI, 但是所有 UE可能都需要对 PDCCH或 ePDCCH进行检测 , 这无疑是对这些 UE的功率的一种浪费。 特别对 MTC UE 来说, 覆盖增强的 PDCCH或 ePDCCH需要大量的信息提取和复杂的盲检测, 如果检测后 MTC UE发现并没有自己的 DCI且当 N很大时 ,对 MTC UE的功 耗浪费很严重, 这一点对于电池供电的 MTC UE来说是很不利的。

具体实施方式 本发明实施例提供了一种触发方法及相关装置, 用于避免 UE对 PDCCH 或 ePDCCH进行不必要的检测, 从而达到节约 UE功率的目的。
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其它实施例, 都属于本发明保护的范围。
以下分别进行详细说明。
实施例一:
请参考图 1 , 图 1为本发明实施例提供的一种触发方法的流程图, 其中, 所述方法包括:
5101、 确定物理触发信道 PTCH的时频资源配置信息;
可以理解的是, 本方法执行主体可以是用户设备 UE (如 MTC UE ), 或 其他发送接收的触发装置, 此处不作具体限定。
其中, 物理触发信道 ( PTCH, Physical Trigger Channel )用于对所述 UE 或其他发送接收的触发装置进行触发。 PTCH的时频资源配置信息包括: PTCH 开始的帧号 PTCH-StartFrame、 子帧号 PTCH-StartSubframe、 时隙序号 PTCH-StartSlot, 符号序号 PTCH-StartSymbol、 周期 Period, PTCH 占用的子 帧数 SubframeLength、PTCH占用的第一个物理资源块( PRB, Physical Resource Block )的序号 FirstPRBNumber、 PTCH占用的 PRB数目 PRBNumber、 PTCH 占用的第一个子载波序号 FirstSubCarrierNumber、 PTCH 占用的子载波数 SubCarrierNumber, PTCH传输所釆用的功率配置 PTCH-Power中的一种或多 种, 所述周期为两个 PTCH之间的时间间隔。
5102、 在所述 PTCH的时频资源配置信息指示的其中一个 PTCH所占用 的时频资源上检测 PTCH;
需要说明的是, 本发明所述的时频资源包括时域资源和频域资源, 时域资 源可以是以帧、 子帧、 时隙或者符号为粒度构成的, 频域资源可以是以 PRB 或者子载波为粒度构成的。
5103、 根据检测 PTCH的结果, 判断是否存在触发;
所述触发用于指示需要在所述 PTCH 关联的第一信息子帧或第一信息机 会上进行第一信息传输; 其中, 所述第一信息为控制、 下行数据、 上行数据中 的一种或多种, 或者, 为增强的控制、 增强的下行数据、 增强的上行数据中的 一种或多种。 所述第一信息传输包括第一信息的接收, 或第一信息的发送。 第 一信息一次传输可以占用一个或多个子帧,所占用的一个或者多个子帧由所述 第一信息子帧或第一信息机会指示。
S104、若判断出存在触发,则在所述 PTCH关联的第一信息子帧或第一信 息机会上进行第一信息传输。
需要说明的是,在本发明实施例中, 所述触发可以包括下行触发和上行触 发:
在下行触发中,控制是指用于包含下行控制信息的控制信道,如控制可以 是 PDCCH , 下行数据是指包含系统信息块( SIB , System Information Block ) 或下行组播消息或下行单播消息的数据信道,如下行数据可以是物理下行共享 信道( PDSCH, Physical Downlink Shared Channel ), 其中, 下行组播消息包括 寻呼消息 paging, 随机接入响应消息 ( RAR, Random Access Response )、 用临 时小区无线网络临时识别符 Temporary C-RNTI加扰的竟争解决消息中的一种 或多种。 当下行数据是用于包含 SIB或下行组播消息的数据信道,控制是用于 包含 SIB 或下行组播消息控制信息的控制信道, 且下行组播消息是寻呼消息 paging时, 这种下行触发称为下行公共触发; 当下行数据是用于包含下行单播 消息的数据信道,控制是用于包含下行单播消息控制信息的控制信道时, 这种 下行触发称为下行专有触发; 当下行数据是用于包含下行组播消息的数据信 道, 控制是用于包含下行组播消息控制信息的控制信道, 且下行组播消息是 RAR或用 Temporary C-RNTI加扰的竟争解决消息时, 这种下行触发称为下行 组触发。
在上行触发中,控制是指用于包含上行控制信息的控制信道,如控制可以 是 PDCCH, 上行数据是指包含上行消息的数据信道, 如上行数据可以是物理 上行共享信道( PUSCH, Physical Uplink Shared Channel )。 在上行触发用于指 示需要在 PTCH 关联的上行数据子帧上或增强的上行数据机会上进行上行数 据或者增强的上行数据的传输,其中上行数据是指包含上行消息的数据信道的 情况下, 当上行消息是随机接入过程中的第三步消息时, 这种上行触发称为上 行组触发, 其它情况下的上行触发称为上行专有触发。
由上述可知,本发明实施例提供的触发方法,通过在 PTCH的时频资源配 置信息指示的其中一个 PTCH所占用的时频资源上,对 PTCH进行检测,若判 断出存在用于指示需要在所述 PTCH 关联的第一信息子帧或第一信息机会上 进行第一信息传输的触发,才进行第一信息的传输,以避免当没有用户设备(如 MTC UE ) 的 DCI时, 用户设备对 PDCCH或者 ePDCCH进行不必要的检测 , 从而达到节约用户设备功率的目的。
进一步地,本发明实施例方案可以应用在基站不对用户设备发送物理控制 格式指示信道(PCFICH, Physical Control Format Indicator Channel ) 以及 PDCCH (或 ePDCCH )的情况, 在这种情况下, 在 PDSCH的时频资源上, 不 论有没有 UE的下行数据, UE都需要进行 PDSCH的检测, 而当没有该 UE的 下行数据时, 这种检测是不必要的, 从而造成功率的浪费。 同时, 不论 UE有 没有上行数据, 基站都要预先预留固定的时频资源用于 UE发送 PUSCH, 如 果为每一个 UE都预留一个固定的 PUSCH时频资源会造成资源的浪费, 如果 允许部分 UE在相同的预留时频资源上发送竟争的 PUSCH, 则会降低基站对 PUSCH的检测性能。 本发明实施例提供的触发方法, 通过在 PTCH的时频资 源配置信息指示的其中一个 PTCH所占用的时频资源上, 对 PTCH进行检测, 若判断出存在用于指示需要在所述 PTCH 关联的第一信息子帧或第一信息机 会上进行第一信息传输的触发, 才进行第一信息的传输, 以避免当没有用户设 备(如 MTC UE ) 的下行数据时, 用户设备对 PDSCH进行不必要的检测, 从 而达到节约用户设备功率的目的。 同时, 解决了 PUSCH的授权问题, 使得基 站对用户设备进行上行触发(授权)之后,用户设备才能进行上行数据的发送, 从而避免了 PUSCH时频资源预留所带来的问题。 实施例二:
请参考图 2, 图 2为本发明实施例提供的触发方法的另一流程图, 以下实 施例中,以 UE为执行主体,对本发明实施例提供的触发方法进行说明,其中, 基于可以通过多种方式确定 PTCH的时频资源配置信息, 所述方法包括:
S201、 根据基站和 UE之间预先约定, 或根据无线资源控制 RRC公共信 令、 RRC专有信令、 媒体接入控制 MAC控制元素 CE信令、 物理层信令、 随 机接入响应 RAR中的一种或多种信令, 确定 PTCH的时频资源配置信息; 其中, 无线资源控制 RRC, 其英文全称为 Radio Resource Control; 媒体 接入控制 MAC, 其英文全称为 Media Access Control; 控制元素 CE, 其英文 全称为 Control Element; 随机接入响应 RAR, 其英文全称为 Random Access Response;
S202、 确定 PTCH关联的第一信息子帧或第一信息机会;
在某些实施方式中,根据 PTCH的时频资源配置信息和预置时间偏移确定 PTCH关联的第一信息子帧或第一信息机会; 或, 根据 PTCH的时频资源配置 信息和第一信息的资源配置信息确定 PTCH 关联的第一信息子帧或第一信息 机会。
其中,第一信息的资源配置信息包括:第一信息传输开始的帧号、子帧号、 时隙序号、 符号序号、 周期、 第一信息一次传输占用的子帧数、 第一信息传输 占用的第一个物理资源块 PRB的序号、 第一信息传输占用的 PRB数目、 第一 信息传输占用的第一个子载波序号、第一信息传输占用的子载波数、第一信息 传输所釆用的功率配置中的一种或多种,所述周期为第一信息两次传输的时间 间隔。
可以理解的是,在确定 PTCH关联的第一信息子帧或第一信息机会( S202 ) 之前还可以包括: 根据 RRC公共信令、 RRC专有信令、 MAC控制元素 CE 信令、 物理层信令、 随机接入响应 RAR中的一种或多种信令, 确定第一信息 的资源配置信息。
需要说明的是,一个 PTCH可以关联一个或者多个第一信息子帧或第一信 息机会。
比如, 假设在 PTCH的时频资源配置信息中, PTCH开始的帧号是 0, 子 帧号是 0, PTCH占用的子帧数是 1个子帧, PTCH的周期是 5毫秒, 假设预 置的时间偏移为 2毫秒,则根据 PTCH的时频资源配置信息和预置时间偏移确 定 PTCH关联的第一信息子帧或第一信息机会, ―个 PTCH关联一个第一信息 子帧或第一信息机会,其中子帧 0上的 PTCH关联的第一信息子帧或第一信息 机会指示的第一信息一次传输可以占用的一个子帧为子帧 2 ,子帧 5上的 PTCH 关联的第一信息子帧或第一信息机会指示的第一信息 ―次传输可以占用的一 个子帧为子帧 7;
又比如, 没在 PTCH的时频资源配置信息中, PTCH开始的帧号是 0, 子帧号是 0, PTCH占用的子帧数是 1个子帧, PTCH的周期是 5毫秒, 假设 在第一信息的资源配置信息中, 第一信息传输开始的帧号是 0, 子帧号是 0, 第一信息传输的周期是 1毫秒, 第一信息一次传输占用的子帧数为 1个子帧, 则根据 PTCH的时频资源配置信息和第一信息的资源配置信息确定 PTCH关联 的第一信息子帧或第一信息机会,一个 PTCH关联多个第一信息子帧或第一信 息机会,其中子帧 0上的 PTCH关联的多个第一信息子帧或第一信息机会指示 的第一信息一次传输可以占用的一个子帧分别为子帧 0、 1、 2、 3、 或 4, 子帧 5上的 PTCH关联的多个第一信息子帧或第一信息机会指示的第一信息一次传 输可以占用的一个子帧分别为子帧 5、 6、 7、 8、 或 9。
S203、 接收一个 PTCH所占用的时频资源上的一个或多个序列; 可以理解的是, 一个 PTCH占用的时域频域资源可以是一个 UE独享, 或 者被一组 UE共享。 在某些实施方式中, 在一个 PTCH占用的时频资源上, 系 统或基站可以发送一个或者多个序列来对一个或者多个 UE进行触发, 则 UE 接收一个 PTCH所占用的时频资源上的一个或多个序列;
其中,序列应具有优良的自相关特性和互相关特性。这些序列可以是具有 零相关区或低相关区特性的序列, 或是 Gold序列、 或是 m序列, 或是计算机 生成的序列等。这些序列也可以是由一个或者多个根序列通过不相同的循环移 位生成的。
S204、利用预配置的序列对在 PTCH的时频资源配置信息指示的其中一个 PTCH所占用的时频资源上接收到的序列进行检测, 得到检测 PTCH的结果。
其中,预配置的序列可以基于序列配置信息确定, 所述序列配置信息包括 序列的索引指示信息 Sequencelndex、 序列的长度指示信息 SequenceLength、 生成序列的根序列索引指示信息 RootSequenceIndex、 根序列的长度指示信息 RootS equenceLength中的一种或多种;
可以理解的是,在根据序列配置信息确定预配置的序列之前,还可以包括 确定序列配置信息的步骤, 在某些实施方式中, 可以基于以下方式确定: 根据基站和 UE之间的预先约定确定序列配置信息; 或, 根据 RRC公共 信令、 RRC专有信令、 MAC控制元素 CE信令、 物理层信令、 RAR中的一种 或多种信令确定序列配置信息; 或, 根据 UE发送的随机接入前导确定序列配 置信息。
其后, 根据得到的检测结果触发步骤 S205a或步骤 S205b;

S205b、 若检测 PTCH的结果小于预置门限, 则判断出不存在触发; 并执行步骤 S206 b;

以下以具体场景为例, 对该实施例提供的触发方法( S201 - S206a /S206b ) 进行详细分析, 其中, 在该应用场景下, UE和基站之间进行交互, 在确定的 PTCH 的时频资源配置信息指示的其中一个 PTCH 所占用的时频资源上检测 PTCH:
当 PTCH用于下行公共触发时, PTCH的时频资源配置信息和 /或序列配 置信息可以是基站和 UE预先约定的, 或者是基站通过 RRC公共信令 (如通过 系统信息块 SIB或主要信息块( MIB, Master Information Block ) )将 PTCH的 时频资源配置信息和 /或序列配置信息通知给 UE。 其中, PTCH的时频资源配 置信息和序列配置信息包括的具体信息可参考前述内容。 例如在 RRC公共信 令 RadioResourceConfigCommon 中可以包含以下信息元素 ( IE, Information Element ):
RadioResourceConfigCommon : : = SEQUENCE {
PTCH-ConfigCommon PTCH-configCommon ,
}
PTCH-ConfigCommon : : = SEQUENCE {
PTCH-StartFrame INTEGER {0,1 , ...1023} ,
PTCH-StartSubframe INTEGER {0,1 , ...9}, PTCH-StartSlot I TEGER{0,1, ...20},
PTCH-StartSymbol INTEGER {0,1 , ...14},
Period ENUMERATED { tl, t2, ....},
SubframeLength ENUMERATED { xl, x2, ....},
FirstPRBNumber ENUMERATED { yl, y2, ....},
PRBNumber ENUMERATED { zl, z2, ....}
PTCH-Power ENUMERATED { pl, p2, ....}.,
Sequencelndex ENUMERATED { si, s2, · ...},
SequenceLength ENUMERATED { 11, 12, ....}, 当 PTCH用于下行组触发和 /或上行组触发时, PTCH的时频资源配置信息 和序列配置信息可以是:
( 1 )基站和 UE预先约定 PTCH的时频资源配置信息和 /或序列配置信息; 或 者,
( 2 )基站通过 RRC公共信令(如通过系统信息块 SIB或主要信息块(MIB, Master Information Block ) )将 PTCH的时频资源配置信息通知给 UE, PTCH釆 用的序列配置信息是根据 UE发送的随机接入前导确定的; 或者,
( 3 ) PTCH的时频资源配置信息是基站和 UE预先约定的, PTCH采用的序 列配置信息是根据 UE发送的随机接入前导确定的; 或者,
( 4 )基站在随机接入响应消息 RAR中包含 PTCH的时频资源配置信息, PTCH采用的序列配置信息是根据 UE发送的随机接入前导确定的; 或者,
( 5 )基站在随机接入响应消息 RAR中包含 PTCH的时频资源配置信息和 / 或采用的序列配置信息。
当 PTCH用于下行专有触发和 /或上行专有触发时, PTCH的时频资源配 置信息和 /或序列配置信息可以是基站和 UE预先约定的,或者是基站通过无线 链路控制 RRC专有信令、媒体接入控制 MAC控制元素 CE信令、物理层信令 中的一种或多种信令, 将 PTCH的时频资源配置信息和 /或釆用的序列配置信 息通知给 UE。 其中, PTCH的时频资源配置信息和序列配置信息包括的具体 信息可参考前述内容。例如在 RRC专有信令 RadioResourceConfigDedicated中 可以包含以下 IE:
RadioResourceConfigDedicated : : = SEQUENCE {
PTCH-ConfigDedicate PTCH-configDedicated,
PTCH-ConfigDedicated : : : = SEQUENCE {
PTCH-StartFrame INTEGER {0,1 , .. .1023},
PTCH-StartSubframe INTEGER {0,1, · . .9},
PTCH-StartSlot INTEGER{0,1, . ..20} ,
PTCH-StartSymbol INTEGER{0,1, . ..14},
Period ENUMERATED { tl, t2, .. ··},
SubframeLength ENUMERATED { xl, x2, · ...},
FirstPRBNumber ENUMERATED { yl, y2, ....},
PRBNumber ENUMERATED { zl, z2, ....]
PTCH-Power ENUMERATED { Pl, p2, · ...}
Sequencelndexl ENUMERATED { si, s2, .. ··},
Sequencelndex2 ENUMERATED { si, s2, · ...},
SequenceLengthl ENUMERATED { 11, 12, · ...},
S equenceLength2 ENUMERATED { 11, 12, · ...}, 需要说明的是, 基站通过 RRC专有信令、 MAC控制元素 CE信令、 物理 层信令中的一种或多种信令通知给 UE的 PTCH的时频资源配置信息和 /或序 列配置信息也可以用于下行公共触发、 下行组触发、上行组触发中的一种或多 种, 这样, 当 PTCH用于下行公共触发、 下行组触发、 上行组触发中的一种或 多种时, 基站就不需要对 PTCH的时频资源配置信息和 /或序列配置信息进行 配置。
基站可以为同一个 UE配置一个 PTCH的时频资源配置信息和一个预配置 的序列, UE可以通过序列的相关检测来判断出是否有触发。 一个 PTCH的时 频资源配置信息和一个预配置的序列可以是多个 UE共享的, 用来对不同的 UE进行触发。 基站可以为同一个 UE配置多个不同的 PTCH的时频资源配置 信息, UE在不同的 PTCH的时频资源配置信息指示的 PTCH所占用的时频资 源上经过相关检测, 检测不同的触发。 基站可以为同一个 UE配置多个预配置 的序列, UE通过不同的预配置的序列来检测不同的触发。 并且, 基站还可以 在不同的 PTCH的时频资源配置信息指示的 PTCH所占用的时频资源上发送相 同的序列用于不同 UE的触发,基站也可以在相同的 PTCH时频资源配置信息 指示的 PTCH所占用的时频资源上发送不同的序列用于不同 UE的触发。
每一个 UE用自己的预配置的序列在为该 UE所配置 PTCH时频资源配置 信息中的一个 PTCH占用的时频资源上对接收到的序列进行相关检测,根据相 关检测的结果来确定在这个 PTCH所占用的时频资源上是否有自己的触发。当 UE在一个 PTCH所占用的时频资源上没有检测到任何触发时, UE将进入微 睡眠状态, 直到在下一个 PTCH所占用的时频资源上对 PTCH进行检测。
在某些实施方式中, 例如: 一个 PTCH包含了 SubframeLength个子帧, 若基站为 UE预配置的序列是长序列, 比如用序列配置信息中序列的长度指示 信息或者根序列的长度指示信息指示预配置的序列是长序列 ,基站将一个长序 列在 SubframeLength 个子帧内发送, UE 用自己的预配置的长序列对在这 SubframeLength个子帧内接收到的序列进行相关检测; 所述相关检测是指,假 设接收到的序列为 ^^..., , 其中 L是序列长度, 基站分配给该 UE的预配置 的序列中一个序列是 , ,...,^, UE做序列的相关运算 |^; |= metric, 如果 metric的值大于等于一个固定的门限值, 则 UE判断在 i£ PTCH上有自己的 触发, 如果 metric的值小于一个固定的门限值, 则 UE判断在这个 PTCH上没 有自己的触发。
若基站为 UE预配置的序列是短序列, 比如用序列配置信息中序列的长度 指示信息或者根序列的长度指示信息指示预配置的序列是短序列 ,基站将一个 短序列在 N (N是正整数)个子帧内发送, 在 SubframeLength个子帧内对这 个短序列进行 M次发送, 其中 M- 1次重复发送 (
Figure imgf000025_0001
M是 正整数), UE用给自己分配的预配置的短序列对接收到的 M次发送的序列进 行相关检测; 所述相关检测包括: 假设在 SubframeLength个子帧内接收到的 序列为 r12,r22,..., ri2,...,r1M, r2M,...,riM , 其中 L是短序列的长度, 基站分配 给该 UE的预配置的短序列中一个序列 ^cl,c2,...,cL ,UE先对这 SubframeLength 个子帧内接收到的序列进行合并,再用分配给自己的预配置的短序列对合并后 或者, UE先用分配给自己
Figure imgf000026_0001
帧内接收到的序列中 M次发 送的序列做相关运算,再把相关运算的结果进行叠加,即为 |;( | ^; |)=η½ώ 。 如果 metric的值大于等于一个固定的门限值,则 UE判断在 Ά PTCH上有自 己的触发, 如果 metric的值小于一个固定的门限值, 则 UE判断在这个 PTCH 上没有自己的触发。
在某些实施方式中, 可以对同一个 UE配置多个预配置的序列, 如为 UE 配置两个预配置的序列, 分别用于 PTCH上行触发和下行触发。 UE只需要在 为其配置的 PTCH的时频资源配置信息指示的 PTCH所占用的时频资源上利用 这两个预配置的序列对接收到的序列进行相关检测,其后就可以根据检测结果 和进行相关检测所釆用的预配置的序列判断是否有自己的上行触发和下行触 发。
由上述可知, 本发明实施例提供的触发方法, 通过在 PTCH的时频资源配 置信息指示的其中一个 PTCH所占用的时频资源上,对 PTCH进行检测,若判 断出存在用于指示需要在所述 PTCH 关联的第一信息子帧或第一信息机会上 进行第一信息传输的触发,才进行第一信息的传输,以避免当没有用户设备(如 MTC UE ) 的 DCI时, 用户设备对 PDCCH或者 ePDCCH进行不必要的检测 , 从而达到节约用户设备功率的目的。进一步地, 本发明实施例方案可以应用在 基站不对用户设备发送 PCFICH以及 PDCCH (或 ePDCCH ) 的情况下, 以避 免当没有用户设备(如 MTC UE )的下行数据时, 用户设备对 PDSCH进行不 必要的检测, 从而达到节约用户设备功率的目的。 同时, 解决了 PUSCH的授 权问题, 使得基站对用户设备进行上行触发(授权)之后, 用户设备才能进行 上行数据的发送, 从而避免了 PUSCH时频资源预留所带来的问题。 实施例三:
请参考图 3 , 图 3为本发明实施例提供的触发方法的另一流程图, 所述方 法 (以 UE是执行主体为例 ) 包括:
S301、 根据基站和 UE之间预先约定, 或根据无线资源控制 RRC公共信 令、 RRC专有信令、 媒体接入控制 MAC控制元素 CE信令、 物理层信令、 随 机接入响应 RAR中的一种或多种信令, 确定 PTCH的时频资源配置信息; S302、 确定 PTCH关联的第一信息子帧或第一信息机会;
可以理解的是, S301和 S302可以参考前述 S201和 S202的相关内容描 述, 此处不再具体阐述。
S303、 接收一个 PTCH所占用的时频资源上 PTCH传输的数据; 所述 PTCH传输的数据承载用于区分上行触发和下行触发的指示信息和 循环冗余校验 CRC ( Cyclic Redundancy Check )信息; 其中, CRC信息使用 小区特定、 UE特定或者一组 UE特定的无线网络临时识别符 RNTI ( Radio Network Temporary Identifier )进行力口扰。
其中, 小区特定的 RNTI是指系统信息无线网络临时识别符 SI-RNTI、 寻 呼无线网络临时识别符 P-RNTI中的一个, UE特定的 RNTI是指小区无线网 络临时识别符 C-RNTI、半静态调度小区无线网络临时识别符 SPS C-RNTL传 输功率控制物理上行控制信道无线网络临时识别符 TPC-PUCCH-RNTI、 传输 功率控制物理上行共享信道无线网络临时识别符 TPC-PUSCH-RNTI 中的一 个, 一组 UE特定的 RNTI是指随机接入无线网络临时识别符 RA-RNTI、 临时 小区无线网络临时识别符 Temporary C-RNTI中的一个。
可以理解的是, PTCH传输的数据承载的信息可以理解为 1比特指示信息 后添加 16比特的 CRC信息 (CRC的比特数也可以是其他值, 本实施例以比 特数是 16为例进行描述), 本实施例中, 当所述 1比特指示信息为 0时可以指 示 PTCH用于上行触发,当所述 1比特指示信息为 1时可以指示 PTCH用于下 行触发,其中,下行触发可以分为下行公共触发、下行组触发和下行专有触发; 上行触发可以分为上行组触发和上行专有触发。不同触发的定义可以如实施例 一中所述, 此处不再具体阐述。
当这 1比特指示信息是 0, 且 PTCH用于上行专有触发时, 用 C-RNTI、 SPS C-RNTL TPC-PUCCH-RNTK TPC-PUSCH-RNTI中的一个对 16比特的 CRC进行加扰; 当这 1 比特指示信息是 0, 且 PTCH用于上行组触发时, 用 Temporary C-RNTI对 16比特的 CRC进行加扰; 当这 1比特指示信息是 1 , 且 PTCH用于下行公共触发时, 用 SI-RNTI或 P-RNTI对 16比特的 CRC进行加 扰; 当这 1 比特指示信息是 1 , 且 PTCH用于下行组触发时, 用 Temporary C-RNTI或 RA-RNTI对 16比特的 CRC进行加扰; 当这 1比特指示信息是 1 , 且 PTCH用于下行专有触发时, 用 C-RNTI或 SPS C-RNTI对 16比特的 CRC 信息进行加扰。 可选的, 也可以用一组 UE特定的无线网络临时识别符对 16 比特的 CRC信息进行加扰, 用来对一组不同的 UE进行触发。 比如, 用组无 线网络临时识别符 G-RNTI对 16比特的 CRC信息进行加扰, 其中, G-RNTI 的取值可以是根据签约消息 (IMSI )和 /或设备信息 (IMEI )按照预定的规则 得到的, 如, G-RNTI= ( IMSI ) mod ( X ), 其中, X为固定的数值, mod ( ) 为取模运算。
5304、 在 PTCH的时频资源配置信息指示的其中一个 PTCH所占用的时 频资源上, 提取接收到的 PTCH传输的数据在每个子帧内的 PTCH信息;
5305、 对提取的 PTCH信息进行先合并后译码, 或者对提取的 PTCH信 息进行先译码后合并;
5306、使用所述小区特定、 UE特定或者一组 UE特定的 RNTI对所述 CRC 信息进行解扰, 并使用解扰后的 CRC信息进行校验, 根据 CRC校验结果, 得 到检测 PTCH的结果;
其后, 根据得到的检测结果触发步骤 S307a或步骤 S307b;
S307a、 若 CRC校验结果正确, 则判断出存在触发;
其中,若使用小区特定的 RNTI对所述小区 CRC信息进行解扰,并且 CRC 校验结果正确, 则判断出存在公共触发; 若使用 UE特定的 RNTI对所述小区 CRC信息进行解扰, 并且 CRC校验结果正确, 则判断出存在专有触发; 若使 用一组 UE特定的 RNTI对所述小区 CRC信息进行解扰, 并且 CRC校验结果 正确, 则判断出存在组触发; 并执行步骤 S308a;
S307b、 若 CRC校验结果不正确, 则判断出不存在触发;
并执行步骤 S308b;
S308a、 若判断出存在触发, 则在所述 PTCH关联的第一信息子帧或第一 信息机会上进行第一信息传输;
S308b、 若判断出不存在触发, 则所述 UE进入微睡眠状态, 直到在下一 个 PTCH所占用的时频资源上对 PTCH进行检测。
以下以具体场景为例, 对该实施例提供的触发方法( S301- S308a /S308b ) 进行详细分析, 其中, 在该应用场景下, UE和基站之间进行交互, 在确定的 PTCH 的时频资源配置信息指示的其中一个 PTCH 所占用的时频资源上检测 PTCH:
可以理解的是, 1比特信息添加 16比特的 CRC之后可以视为 17比特信 息, 基站将这 17比特信息在 PTCH的时频资源配置信息指示的一个 PTCH所 占用的时频资源上进行发送。 系统或者基站要预先为 UE配置 PTCH的时频资 源配置信息。 PTCH的时频资源配置信息可以是基站和 UE预先约定的, 或者 是基站通过 RRC公共信令 (如通过 SIB或 MIB )、 RRC专有信令、 MAC控制 元素 CE信令、 物理层信令中的一种或多种信令通知给 UE。 其中, PTCH的 时频资源配置信息包括的具体信息可参考实施例一所述。
例如: 在 RRC公共信令 RadioResourceConfigCommon中可以包含以下 IE: RadioResourceConfigCommon : : = SEQUENCE {
PTCH-ConfigCommon PTCH-configCommon ,
PTCH-ConfigCommon : = SEQUENCE {
PTCH-StartFrame INTEGER {0,1 , ...1023} ,
PTCH-StartSubframe INTEGER {0,1 , ...9} ,
PTCH-StartSlot INTEGER {0,1 , ...20} ,
PTCH-StartSymbol INTEGER {0,1 , ...14} ,
Period ENUMERATED { tl, t2, ....}
SubframeLength ENUMERATED { xl, x2, ....
FirstPRBNumber ENUMERATED { yl, y2, ...
PRBNumber ENUMERATED { zl, z2, .
PTCH-Power ENUMERATED { pl, p2, . 又如, 在 RRC专有信令 RadioResourceConfigDedicated中可以包含以下 IE: RadioResourceConfigDedicated : : = SEQUENCE {
PTCH-ConfigDedicate PTCH-configDedicated , PTCH-ConfigDedicated : = SEQUENCE {
PTCH-StartFrame INTEGER {0,1 , ...1023} ,
PTCH-StartSubframe INTEGER {0,1 , ...9} ,
PTCH-StartSlot INTEGER {0,1 , ...20} ,
PTCH-StartSymbol INTEGER {0,1 , ...14} ,
Period ENUMERATED { tl, t2, ...
SubframeLength ENUMERATED { xl, x2, .
FirstPRBNumber ENUMERATED { yl, y2,
PRBNumber ENUMERATED { zl, z2
PTCH-Power ENUMERATED { pl, p2, 需要说明的是, PTCH的时频资源配置信息所包含的信息中的一种或者多 种也可以根据控制信道, 如 PDCCH、 ePDCCH、 覆盖增强的 PDCCH或者覆盖 增强的 ePDCCH的配置信息来获得, 此处不作具体限定。
若 PTCH的时频资源配置信息指示的一个 PTCH所占用的时频资源包含了 SubframeLength个子帧, 基站对 17比特的信息按照一个子帧内 PTCH占用的时 频资源大小进行编码, 并对编码后的结果在 SubframeLength个子帧内进行重复 发送; 或者, 基站对 17比特的信息按照 SubframeLength个子帧内 PTCH占用的 时频资源大小进行编码, 并对编码后的结果在 SubframeLength个子帧内进行发 送。
UE在 PTCH的时频资源配置信息指示的其中一个 PTCH所占用的时频资源 上, 先提取 SubframeLength个子帧内接收到的 PTCH传输的数据在每个子帧内 的 PTCH信息, 对这 SubframeLength个子帧内的 PTCH信息进行先合并后译码, 或者先译码再合并, 在译码或者译码再合并之后, 用小区特定、 UE特定或者 一组 UE特定的 RNTI对 CRC进行解扰, 而后用 CRC进行校验。 如果 CRC校验成 功, 则 UE可以根据检测出来的这 1比特指示信息的取值来区分上行触发和下行 触发; 如果校验失败, 则判断出没有自己的触发, UE将进入微睡眠状态, 直 到在下一个 PTCH所占用的时频资源上对 PTCH进行检测。
由上述可知,本发明实施例提供的触发方法,通过在 PTCH的时频资源配 置信息指示的其中一个 PTCH所占用的时频资源上,对 PTCH进行检测,若判 断出存在用于指示需要在所述 PTCH 关联的第一信息子帧或第一信息机会上 进行第一信息传输的触发,才进行第一信息的传输,以避免当没有用户设备(如 MTC UE ) 的 DCI时, 用户设备对 PDCCH或者 ePDCCH进行不必要的检测 , 从而达到节约用户设备功率的目的。进一步地, 本方案可以应用在基站不对用 户设备发送 PCFICH以及 PDCCH (或 ePDCCH ) 的情况下, 以避免当没有用 户设备 (如 MTC UE )的下行数据时,用户设备对 PDSCH进行不必要的检测, 从而达到节约用户设备功率的目的。 同时, 解决了 PUSCH的授权问题, 使得 基站对用户设备进行上行触发(授权)之后, 用户设备才能进行上行数据的发 送, 从而避免了 PUSCH时频资源预留所带来的问题。 实施例四:

可以理解的是, 发送 PTCH后,使得 UE在一个 PTCH所占用的时频资源 上对发送的 PTCH进行检测, 并根据检测 PTCH的结果, 判断是否存在触发; 所述触发用于指示需要在所述 PTCH 关联的第一信息子帧或第一信息机会上 进行第一信息传输; 其中, 所述第一信息为控制、 下行数据、 上行数据中的一 种或多种, 或者, 为增强的控制、 增强的下行数据、 增强的上行数据中的一种 或多种; 若判断出存在触发, 则所述 UE在所述 PTCH关联的第一信息子帧或 第一信息机会上进行第一信息传输; 进一步地, 若判断出不存在触发, 则所述 UE进入 睡眠状态, 直到在下一个 PTCH所占用的时频资源上对 PTCH进行 检测。
需要说明的是,本发明实施例中 ,所述触发可以包括下行触发和上行触发, 其中下行触发可以分为下行公共触发、 下行组触发和下行专有触发, 上行触发 可以分为上行组触发和上行专有触发。 不同触发的定义可以如实施例一所述, 此处不再具体阐述。
由上述可知,本发明实施例提供的触发方法,通过在 PTCH的时频资源配 置信息指示的其中一个 PTCH所占用的时频资源上,对 PTCH进行发送,用户 设备对其进行接收检测,若判断出存在用于指示需要在所述 PTCH关联的第 ― 信息子帧或第一信息机会上进行第一信息传输的触发, 才进行第一信息的传 输, 以避免当没有用户设备 (如 MTC UE )的 DCI时, 用户设备对 PDCCH或 者 ePDCCH进行不必要的检测, 从而达到节约用户设备功率的目的。 进一步 地, 本发明实施例方案可以应用在基站不对用户设备发送 PCFICH 以及 PDCCH (或 ePDCCH ) 的情况下, 以避免当没有用户设备(如 MTC UE ) 的 下行数据时, 用户设备对 PDSCH进行不必要的检测, 从而达到节约用户设备 功率的目的。 同时, 解决了 PUSCH的授权问题, 使得基站对用户设备进行上 行触发(授权)之后,用户设备才能进行上行数据的发送,从而避免了 PUSCH 时频资源预留所带来的问题。 实施例五:
请参考图 5, 图 5为本发明实施例提供的另一种触发方法的另一流程图, 以下实施例中,以基站为执行主体,对本发明实施例提供的触发方法进行说明, 其中, 所述方法包括:
S501、 根据基站和 UE之间预先约定, 确定 PTCH的时频资源配置信息; 或, 预先设置 PTCH的时频资源配置信息;
其中,基站预先设置 PTCH的时频资源配置信息后,还包括发送无线资源 控制 RRC公共信令、 RRC专有信令、 媒体接入控制 MAC控制元素 CE信令、 物理层信令、 随机接入响应 RAR中的一种或多种信令, 在所述一种或多种信 令中包含所述 PTCH的时频资源配置信息。 5502、 确定 PTCH关联的第一信息子帧或第一信息机会;
在某些实施方式中,根据 PTCH的时频资源配置信息和预置时间偏移确定 PTCH关联的第一信息子帧或第一信息机会; 或, 根据 PTCH的时频资源配置 信息和第一信息的资源配置信息确定 PTCH 关联的第一信息子帧或第一信息 机会。

5503、在所述一个 PTCH所占用的时频资源上发送一个或多个序列,使得 UE利用预配置的序列对在 PTCH的时频资源配置信息指示的其中一个 PTCH 所占用的时频资源上接收到的序列进行检测, 得到检测 PTCH的结果;
其中, 所述预配置的序列基于序列配置信息确定,序列配置信息包括序列 的索引指示信息、序列的长度指示信息、 生成序列的根序列索引指示信息、 根 序列的长度指示信息中的一种或多种;
可以理解的是,在根据序列配置信息确定预配置的序列之前,还可以包括 确定序列配置信息的步骤, 在某些实施方式中, 可以基于以下方式确定:
根据基站和 UE之间的预先约定确定序列配置信息; 或, 预先设置序列配 置信息, 并发送 RRC公共信令、 RRC专有信令、 MAC控制元素 CE信令、 物 理层信令、 随机接入响应 RAR中的一种或多种信令, 在所述一种或多种信令 中包含所述序列配置信息; 或, 根据 UE发送的随机接入前导确定序列配置信 息。
需要说明的是, 基站通过 RRC专有信令、 MAC控制元素 CE信令、 物理 层信令中的一种或多种信令通知给 UE的 PTCH的时频资源配置信息和 /或序 列配置信息也可以用于下行公共触发、 下行组触发、上行组触发中的一种或多 种, 这样, 当 PTCH用于下行公共触发、 下行组触发、 上行组触发中的一种或 多种时, 基站就不需要对 PTCH的时频资源配置信息和 /或序列配置信息进行 配置。
基站可以为同一个 UE配置一个 PTCH的时频资源配置信息和一个预配置 的序列, UE可以通过序列的相关检测来判断出是否有触发。 一个 PTCH的时 频资源配置信息和一个预配置的序列可以是多个 UE共享的, 用来对不同的 UE进行触发。 基站可以为同一个 UE配置多个不同的 PTCH的时频资源配置 信息, UE在不同的 PTCH的时频资源配置信息指示的 PTCH所占用的时频资 源上经过相关检测, 检测不同的触发。 基站可以为同一个 UE配置多个预配置 的序列, UE通过不同的预配置的序列来检测不同的触发。 并且, 基站还可以 在不同的 PTCH的时频资源配置信息指示的 PTCH所占用的时频资源上发送相 同的序列用于不同 UE的触发,基站也可以在相同的 PTCH时频资源配置信息 指示的 PTCH所占用的时频资源上发送不同的序列用于不同 UE的触发。
可以理解的是, UE侧得到检测 PTCH的结果后, 可以根据检测结果判断 是否存在触发;若检测 PTCH的结果大于或等于预置门限,则判断出存在触发, 若检测 PTCH的结果小于预置门限,则判断出不存在触发;若判断出存在触发, 则在所述 PTCH关联的第一信息子帧或第一信息机会上进行第一信息传输;进 一步地, 若判断出不存在触发, 则所述 UE 进入微睡眠状态, 直到在下一个 PTCH所占用的时频资源上对 PTCH进行检测。
所属领域的技术人员可以清楚地了解到, 为描述的方便和简洁, 本是实施 例描述的基站侧触发方法各步骤的具体工作过程和具体应用场景,可以参考前 述 UE侧方法实施例二中的对应过程, 在此不再赘述。
由上述可知,本发明实施例提供的触发方法,通过在 PTCH的时频资源配 置信息指示的其中一个 PTCH所占用的时频资源上,对 PTCH进行发送,用户 设备对其进行接收检测,若判断出存在用于指示需要在所述 PTCH关联的第 ― 信息子帧或第一信息机会上进行第一信息传输的触发, 才进行第一信息的传 输, 以避免当没有用户设备 (如 MTC UE )的 DCI时, 用户设备对 PDCCH或 者 ePDCCH进行不必要的检测, 从而达到节约用户设备功率的目的。 进一步 地, 本发明实施例方案可以应用在基站不对用户设备发送 PCFICH 以及 PDCCH (或 ePDCCH ) 的情况下, 以避免当没有用户设备(如 MTC UE ) 的 下行数据时, 用户设备对 PDSCH进行不必要的检测, 从而达到节约用户设备 功率的目的。 同时, 解决了 PUSCH的授权问题, 使得基站对用户设备进行上 行触发(授权)之后,用户设备才能进行上行数据的发送,从而避免了 PUSCH 资源预留所带来的问题。 实施例六:

S603、 在所述一个 PTCH所占用的时频资源上发送 PTCH传输的数据; 其中,所述 PTCH传输的数据承载用于区分上行触发和下行触发的指示信 息和循环冗余校验 CRC信息; 使用小区特定、 UE特定或者一组 UE特定的无 线网络临时识别符 RNTI对 CRC信息进行加扰, 使得 UE在 PTCH的时频资 源配置信息指示的其中一个 PTCH所占用的时频资源上,提取接收到的 PTCH 传输的数据在每个子帧内的 PTCH信息;对提取的 PTCH信息进行先合并后译 码, 或者对提取的 PTCH信息进行先译码后合并; 使用所述小区特定、 UE特 定或者一组 UE特定的 RNTI对所述 CRC信息进行解扰,并使用解扰后的 CRC 信息进行校验, 根据 CRC校验结果, 得到检测 PTCH的结果。
其中, 小区特定的 RNTI是指系统信息无线网络临时识别符 SI-RNTI、 寻 呼无线网络临时识别符 P-RNTI中的一个, UE特定的 RNTI是指小区无线网 络临时识别符 C-RNTI、半静态调度小区无线网络临时识别符 SPS C-RNTI、传 输功率控制物理上行控制信道无线网络临时识别符 TPC-PUCCH-RNTI、 传输 功率控制物理上行共享信道无线网络临时识别符 TPC-PUSCH-RNTI 中的一 个, 一组 UE特定的 RNTI是指随机接入无线网络临时识别符 RA-RNTI、 临时 小区无线网络临时识别符 Temporary C-RNTI中的一个。
可以理解的是, PTCH传输的数据承载的信息可以理解为 1比特指示信息 后添加 16比特的 CRC信息 (CRC的比特数也可以是其他值, 本实施例以比 特数是 16为例进行描述), 本实施例中, 当所述 1比特指示信息为 0时可以指 示 PTCH用于上行触发,当所述 1比特指示信息为 1时可以指示 PTCH用于下 行触发,其中,下行触发可以分为下行公共触发、下行组触发和下行专有触发; 上行触发可以分为上行组触发和上行专有触发。不同触发的定义可以如实施例 一中所述, 此处不再具体阐述。
当这 1比特指示信息是 0, 且 PTCH用于上行专有触发时, 用 C-RNTI、 SPS C-RNTL TPC-PUCCH-RNTK TPC-PUSCH-RNTI中的一个对 16比特的 CRC进行加扰; 当这 1 比特指示信息是 0, 且 PTCH用于上行组触发时, 用 Temporary C-RNTI对 16比特的 CRC进行加扰; 当这 1比特指示信息是 1 , 且 PTCH用于下行公共触发时, 用 SI-RNTI或 P-RNTI对 16比特的 CRC进行加 扰; 当这 1 比特指示信息是 1 , 且 PTCH用于下行组触发时, 用 Temporary C-RNTI或 RA-RNTI对 16比特的 CRC进行加扰; 当这 1比特指示信息是 1 , 且 PTCH用于下行专有触发时, 用 C-RNTI或 SPS C-RNTI对 16比特的 CRC 信息进行加扰。 可选的, 也可以用一组 UE特定的无线网络临时识别符对 16 比特的 CRC信息进行加扰, 用来对一组不同的 UE进行触发。 比如, 用组无 线网络临时识别符 G-RNTI对 16比特的 CRC信息进行加扰, 其中, G-RNTI 的取值可以是根据签约消息 (IMSI )和 /或设备信息 (IMEI )按照预定的规则 得到的, 如, G-RNTI= ( IMSI ) mod ( X ), 其中, X为固定的数值, mod ( ) 为取模运算。
若 PTCH的时频资源配置信息指示的一个 PTCH所占用的时频资源包含了 SubframeLength个子帧, 基站对 17比特的信息按照一个子帧内 PTCH占用的 时频资源大小进行编码, 并对编码后的结果在 SubframeLength个子帧内进行 重复发送; 或者, 基站对 17比特的信息按照 SubframeLength个子帧内 PTCH 占用的时频资源大小进行编码, 并对编码后的结果在 SubframeLength个子帧 内进行发送。
可以理解的是, UE侧得到检测 PTCH的结果后, 可以根据检测结果判断 是否存在触发; 若使用小区特定的 RNTI对所述小区 CRC信息进行解扰, 并 且 CRC校验结果正确, 则判断出存在公共触发; 若使用 UE特定的 RNTI对 所述小区 CRC信息进行解扰, 并且 CRC校验结果正确, 则判断出存在专有触 发; 若使用一组 UE特定的 RNTI对所述小区 CRC信息进行解扰, 并且 CRC 校验结果正确, 则判断出存在组触发, 若 CRC校验结果不正确, 则判断出不 存在触发; 若判断出存在触发,则在所述 PTCH关联的第一信息子帧或第一信 息机会上进行第一信息传输; 进一步地, 若判断出不存在触发, 则所述 UE进 入啟睡眠状态, 直到在下一个 PTCH所占用的时频资源上对 PTCH进行检测。
所属领域的技术人员可以清楚地了解到, 为描述的方便和简洁, 本是实施 例描述的基站侧触发方法各步骤的具体工作过程和具体应用场景,可以参考前 述 UE侧方法实施例三中的对应过程, 在此不再赘述。
由上述可知,本发明实施例提供的触发方法,通过在 PTCH的时频资源配 置信息指示的其中一个 PTCH所占用的时频资源上,对 PTCH进行发送,用户 设备对其进行接收检测,若判断出存在用于指示需要在所述 PTCH关联的第 ― 信息子帧或第一信息机会上进行第一信息传输的触发, 才进行第一信息的传 输, 以避免当没有用户设备 (如 MTC UE )的 DCI时, 用户设备对 PDCCH或 者 ePDCCH进行不必要的检测, 从而达到节约用户设备功率的目的。 进一步 地, 本方案可以应用在基站不对用户设备发送 PCFICH 以及 PDCCH (或 ePDCCH ) 的情况下, 以避免当没有用户设备 (如 MTC UE ) 的下行数据时, 用户设备对 PDSCH进行不必要的检测, 从而达到节约用户设备功率的目的。 同时,解决了 PUSCH的授权问题,使得基站对用户设备进行上行触发(授权) 之后, 用户设备才能进行上行数据的发送, 从而避免了 PUSCH资源预留所带 来的问题。 为便于更好的实施本发明实施例的技术方案,本发明实施例还提供用于实 施上述触发方法的相关装置。其中名词的含义与上述触发方法中相同, 具体实 现细节可以参考方法实施例中的说明。
