MTC终端与网络侧进行数据传输的时间是可控的, 即 MTC终端只能在网 络指定的时间段内进行接入;
MTC终端与网络侧进行的数据传输对实时性要求不高, 即: 具有时间容 忍性;
MTC终端能量受限, 要求极低的功率消耗;
MTC终端和网络侧之间只进行小数据量的信息传输;

为了使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本 发明作进一步地详细描述, 显然, 所描述的实施例仅仅是本发明一部份实施 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 没有做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。
针对无线信号被严重遮挡的场景, 本发明实施例提供一种系统信息的发 送、 接收方案, 以使终端能够正确获取信息。 本发明实施例中, 网络侧在特 定 SIB的每个重复周期内: 重复调度该特定 SIB, 并在特定 SIB的调度时机重复 发送特定 SIB; 终端在特定 SIB的每个重复周期内: 重复接收该特定 SIB的调度 信息, 并在获取调度信息后, 在特定 SIB的调度时机重复接收下行信号。
现有的 LTE系统中, 在 SIB的一个重复周期内, 该 SIB仅发送一次, 这里的 SIB不包含 SIB1 , 比如可以是 SIB2。 当无线信号被严重遮挡时, 终端需要合并 多个重复周期内接收到的下行信号以解调获取系统信息。 显然, 在一个 SIB修 改周期内重复的次数不足以支持在终端的解调需求。 本发明实施例提供的技 术方案, 网络侧在特定 SIB的一个重复周期内重复发送特定 SIB; 相应的, 终 端可以在特定 SIB的一个重复周期内特定 SIB的调度时机重复接收下行信号, 如果重复次数足够多, 则可以合并一个重复周期内接收到的下行信号从而正 确解调出该特定 SIB。 即使无法在一个重复周期内正确解调出该特定 SIB , 由 于在重复周期内重复发送特定 SIB, 那么, 在一个 SIB修改周期内重复的次数 也较之现有技术至少增加一倍, 从而能够满足终端的解调需求, 提高系统性

匕。
在详细描述本发明实施例提供的技术方案之前, 首先对本发明实施例中 涉及到的技术名词进行解释:
SIB的重复周期: 现有实现中, 除了 SIB1之外, 其他类型的 SIB的重复周 期是指该 SIB的发送周期。 假设 SIB2的重复周期为 320ms, 按照现有实现, 每 隔 320ms传输一次 SIB2。 而本发明实施例中, 会在特定 SIB的重复周期内重复 发送特定 SIB。
SI消息的时间窗 (英文: SI-wmdows ): 除了 SIB1之外, 其他类型的 SIB 均需要映射到 SI消息中进行传输。 每个 SI消息关联一个时间窗, 不同 SI消息的 时间窗不重叠,每个 SI消息的时间窗的长度相同且可以通过 SIB1配置。 SI消息 在其时间窗内以动态调度方式传输。 那么, 在特定 SIB的重复周期内, 重复传 输特定 SIB的无线帧构成 SI消息的时间窗。
SIB的修改周期: SIB的改变发生在特定的无线帧处。 假设在修改周期 L 上, 网络侧向终端发送了 SIB的变更通知, 但在该修改周期 L上, 仍然发送 /接 收当前 SIB, 等到下一修改周期 L+1到来时, 发送 /接收变更后的 SIB。
特定 SIB: 是指终端进行通信所需的 SIB。 对于不同的通信过程或通信阶 段, 终端所需的 SIB不同, 那么特定 SIB也不同。 具体将哪种类型的 SIB作为特 定 SIB, 需要根据具体的通信场景判断, 本发明不作限定。 例如, 在终端接入 过程中, 需要根据 SIB2携带的小区无线配置信息和其他基站配置信息完成接 入, 那么, SIB2就是特定 SIB。
终端: 本发明实施例中描述的终端可以是 MTC终端, 当然, 也可以是用 户设备 ( UE )。 但特别适用于 MTC终端, 尤其是信号遮挡严重的 MTC终端。 基站: 本发明实施例中描述的基站可以是 LTE系统中的演进型基站 ( eNB ), 也可以是在 LTE系统基础上更高演进版本的通信系统中的基站。
下面将结合附图, 对本发明实施例提供的技术方案进行详细说明。
本发明实施例提供的一种系统信息的发送方法如图 1所示, 在特定 SIB的 每个重复周期内, 本发明实施例提供的方法具体包括如下操作:
步骤 100、 重复发送该特定 SIB的调度信息。
发送特定 SIB的调度信息, 也就是对该 SIB存在映射关系的 SI消息进行调 度。
步骤 110、 在该特定 SIB的调度时机重复发送该特定 SIB。
其中, 在该特定 SIB的修改周期内, 发送特定 SIB的子帧在重复周期中的 相对位置相同。
本发明实施例中,特定 SIB的重复周期的长度可以是 SIB 1中通知的最小重 复周期。 特定 SIB的重复周期的长度也可以是 SIB1中通知的最大重复周期。 特 定 SIB的重复周期的长度还可以是协议约定或者网络侧确定的其他重复周期 长度, 以特定 SIB是 SIB2为例, 其重复周期的长度可以沿用目前常用配置长度 320ms
应当指出的是, 特定 SIB在传输时, 需要避开 SIB1和 MBSFN传输所在的 子帧。 如果是 TDD系统, 还需要避开上行子帧和特殊子帧。
基于上述发送方法实施例, 特定 SIB的调度时机, 可以是通过协议预先约 定或网络侧确定的特定 SIB的重复周期内连续 M个无线帧, 其中, M为大于 0 小于等于所述特定 SIB的重复周期次数的整数, 也可以是通过协议预先约定的 发送该特定 SIB的发送时机图样(英文: pattern )中规定的发送特定 SIB的时机 (即规定发送特定 SIB的无线帧在特定 SIB的重复周期中的相对位置, 或者, 规定发送特定 SIB的子帧在无线帧中的编号和所述无线帧在特定 SIB的重复周 期中的相对位置)。
如果特定 SIB的重复周期的连续 M个无线帧中, 重复发送上述特定 SIB。 所述连续 M个无线帧即与该特定 SIM存在映射关系的 SI消息的时间窗。 该时间 窗的长度(M ) 既可以在协议中预先约定, 也可以由网络侧确定并通过 SIB1 告知终端。 另外, 该时间窗在重复周期中的位置可以在协议中预先约定, 也 可以由网络侧确定并通过 SIB 1告知终端。
其中, 既可以在所述连续 M个无线帧的每个子帧上均发送上述特定 SIB, 也可以根据协议约定或网絡侧的决定,在所述连续 M个无线帧的部分子帧上发 送上述特定 SIB。 对于在部分子帧上发送特定 SIB的情况, 具体的, 所述连续 M个无线帧中, 每个无线帧上用于发送特定 SIB的子帧编号相同。 如果由网络 侧决定哪些子帧用于传输特定 SIB, 则网络侧还需要通过 SIB1将这些子帧的编 号告知终端。 无论在全部或者部分子帧上发送特定 SIB, 发送特定 SIB的子帧 不是 SIB1和 MBSFN传输所在的子帧, 对于 TDD系统, 也不是上行子帧和特殊 子帧。
其中, 如图 2所示, 所述连续 M个无线帧在特定 SIB的重复周期内的一种 实现方式可以是: 所述连续 M个无线帧的起始无线帧, 与特定 SIB的重复周期 中调度其他 SIB的最后一个无线帧相邻。
如图 3所示, 所述连续 M个无线帧在特定 SIB的重复周期内的另一种实现 方式可以是: 所述连续 M个无线帧可以是特定 SIB的重复周期的最后 M个无线 帧。
应当指出的是, 现有技术中, SIB在其映射到的 SI消息的一个时间窗内, 仅传输一次。 而本发明实施例中, 特定 SIB会在与其存在映射关系的 SI消息的 时间窗内重复传输。
根据上述发送时机 pattern中规定的发送特定 SIB的时机,在特定 SIB的重复 周期内重复发送该特定 SIB。 具体的, 从预先约定的 (即协议约定的)发送特 定 SIB的发送时机 pattern中选择一个发送时机 pattern (如图 4所示); 按照选择 的发送时机 pattern重复发送上述特定 SIB。
其中,选择发送时机 pattern的具体实现方式根据实际通信需求确定,例如, 选择的发送时机 pattern规定的发送特定 SIB的时机需要避开传输 SIB 1的子帧、 传输 MBSFN的子帧。 对于 TDD系统, 还需要避开上行子帧和特殊子帧。
进一步的, 在特定 SIB的每个重复周期内, 还将发送时机 pattern的选择结 果携带在 SIB1中发送给终端。该选择结果既可以是选择的发送时机 pattern的具 体内容, 也可以是选择的发送时机 pattern的标识或者编号。
由于 SI消息是由 PDCCH调度传输的。 因此, 对于每个特定 SIB, 还传输相 应的 PDCCH以对特定 SIB进行调度。
基于上述任意发送方法实施例,较佳地,步骤 100的具体实现方式可以是: 在发送上述特定 SIB的子帧上发送用于调度该特定 SIB的 PDCCH , 且每个 PDCCH携带的下行控制信息 ( Downlink Control Information, 简称: DCI )相 同。也就是说,调度特定 SIB的 PDCCH的发送时机与特定 SIB的调度时机相同。 当然, 调度特定 SIB的 PDCCH的发送时机, 也可以早于特定 SIB的调度时机。
本发明实施例提供的一种系统信息的接收方法如图 5所示, 特定 SIB的每 个重复周期内, 本发明实施例提供的方法具体包括如下操作:
步骤 500、 重复接收该特定 SIB的调度信息。
对特定 SIB的重复周期的长度, 与网络侧发送特定 SIB的重复周期的长度 相同, 具体可以参照上述发送方法侧实施例的描述, 这里不再赘述。
步骤 510、 获取该特定 SIB的调度信息后, 在该特定 SIB的调度时机重复接 收下行信号, 以根据接收到的下行信号获取该特定 SIB。
其中, 在特定 SIB的修改周期内, 每个重复周期接收上述下行信号的子帧 在重复周期中的相对位置相同。
基于上述接收方法实施例, 特定 SIB的调度时机, 可以是通过协议预先约 定或网络侧确定的重复周期内连续 M个无线帧,也可以是通过协议预先约定的 发送该特定 SIB的发送时机图样(英文: pattern )中规定的发送特定 SIB的时机 (即规定发送特定 SIB的无线帧在特定 SIB的重复周期中的相对位置, 或者, 规定发送特定 SIB的子帧在无线帧中的编号和所述无线帧在特定 SIB的重复周 期中的相对位置)。
在特定 SIB的重复周期的连续 M个无线帧中, 重复接收下行信号。 所述连 续 M个无线帧即为与该特定 SIM存在映射关系的 SI消息的时间窗。 该时间窗的 长度(M ) 既可以在协议中预先约定, 也可以从 SIB1中获知。 另外, 该时间 窗在 SI周期中的位置可以在协议中预先约定, 也可以从 SIB1中获知。
其中, 如果网络侧在所述连续 M个无线帧的每个子帧上均发送上述特定 SIB,则终端可以在所述连续 M个无线帧的每个子帧上均接收下行信号。 当然, 如果通过合并前若干个子帧接收到下行信号正确解调出特定 SIB, 则无需继续 在所述 M个无线帧后续子帧上接收特定 SIB对应的下行信号。
如果网络侧在所述连续 M个无线帧的部分子帧上发送上述特定 SIB, 则终 端可以在所述连续 M个无线帧的部分子帧上接收下行信号。 当然,如果通过合 并前若干子帧接收到下行信号正确解调出特定 SIB, 则无需继续在所述 M个无 线帧后续子帧上接收特定 SIB对应的下行信号。
对于在部分子帧上接收下行信号的情况,具体的,所述连续 M个无线帧中, 每个无线帧上用于发送特定 SIB的子帧编号相同。 如果由网络侧决定哪些子帧 用于传输特定 SIB , 则终端在 SIB1中获知这些子帧的编号。
无论在全部或者部分子帧上接收下行信号, 接收下行信号的子帧不是 SIB1和 MBSFN传输所在的子帧,对于 TDD系统,也不是上行子帧和特殊子帧。
在特定 SIB的重复周期的所述连续 M个无线帧的全部或部分子帧上, 接收 所述下行信号, 接收所述下行信号的子帧不是 SIB1和 MBSFN传输所在的子 帧, 也不是上行子帧和特殊子帧。
其中, 所述连续 M个无线帧在 SI周期内的具体实现方式与发送特定 SIB的 网络侧相同。 具体可以参见上述发送方法实施例的描述, 这里不再赘述。
如果根据上述发送时机 pattern中规定的发送特定 SIB的时机, 在特定 SIB 的重复周期内重复接收下行信号。 那么, 在特定 SIB的每个重复周期内, 还从 接收到的 SIB1中获取发送该特定 SIB的发送时机 pattern的选择结果; 从预先约 定的发送特定 SIB的发送时机 pattern中,确定选择结果指示的发送时机 pattern; 按照确定的发送时机图样重复接收下行信号。 其中, 对于发送该特定 SIB的发 送时机 pattern的描述可以参照上述发送方法实施例, 这里不再赘述。 由于 SI消息是由 PDCCH调度传输的。 因此, 对于每个特定 SIB, 还从相应 的 PDCCH获取特定 SIB的调度信息。 基于上述任意接收方法实施例, 较佳地, 步骤 500的具体实现方式可以是: 在接收上述下行信号的子帧上接收用于调度 特定 SIB的 PDCCH, 且每个 PDCCH携带的 DCI相同。 也就是说, 调度特定 SIB 的 PDCCH的发送时机与特定 SIB的调度时机相同。 当然, 调度特定 SIB的 PDCCH的发送时机, 也可以早于特定 SIB的调度时机。
以图 2所示的调度时机为例, 对网络侧发送特定 SIB , 以及终端接收特定 SIB的具体实现方式进行说明。
其中, 网络侧的处理过程可以描述为:
每个特定 SIB的重复周期内, 基站在该重复周期中系统帧号 (SFN ) 为 N-M ~ N的最后 M个无线帧上, 重复发送用于调度特定 SIB的 PDCCH, 并重复 发送特定 SIB。应当指出的是,此处的 SFN是无线帧在重复周期中的相对位置。
具体的, 基站在这 M个无线帧中, SIB1传输所在的子帧和 MBSFN传输所 在的子帧之外的各个子帧上, 调度特定 SIB的 PDCCH, 这些子帧上传输的 PDCCH的 DCI相同。 并在这些子帧上, 在 PDCCH调度的时频资源上发送特定 SIB。
如果特定 SIB的重复周期的长度是基站确定的, 则基站还在 SIB1中携带特 定 SIB的重复周期的长度。
如果 M的取值是基站确定的, 则基站还在 SIB1中携带 M的取值。
终端测的处理过程可以描述为:
每个特定 SIB的重复周期内, 终端在该重复周期中系统帧号为 N-M ~ N的 最后 M个无线帧上,重复接收用于调度特定 SIB的 PDCCH,并重复接收特定 SIB 对应的下行信号。应当指出的是, 此处的 SFN是无线帧在重复周期中的相对位 置。
具体的, 终端在这 M个无线帧中, SIB1传输所在的子帧和 MBSFN传输所 在的子帧之外的各个子帧上,接收调度特定 SIB的 PDCCH,这些子帧上传输的 PDCCH的 DCI相同。 通过合并接收到的信号正确解调出 PDCCH后, 从中获取 特定 SIB的调度信息。 当然, 如果通过合并部分子帧上接收到的信号就正确解 调出 PDCCH, 则后续不用继续接收 PDCCH。
在获取特定 SIB的调度信息后, 终端在这些子帧上, 在特定 SIB的调度信 息指示的时频资源上接收下行信号。 通过合并接收到的下行信号正确解调出 特定 SIB。 当然, 如果通过合并部分子帧上接收到的信号就正确解调出特定 SIB, 则后续不用继续在调度信息指示的时频资源上继续接收下行信号。
如果 PDCCH先被正确解调, 将会出现的情况是, 终端在某个子帧上仅需 要接收特定 SIB对应的下行信号, 不需要接收 PDCCH。 那么, 终端可以根据之 前正确解调出的 PDCCH中携带的特定 SIB的调度信息,在该调度信息指示的时 频资源上接收下行信号。
如果特定 SIB的重复周期的长度是基站确定的, 则终端还在 SIB1中获取特 定 SIB的重复周期的长度。
如果 M的取值是基站确定的, 则终端还在 SIB1中获取 M的取值。
以图 3所示的调度时机为例, 对网络侧发送特定 SIB, 以及终端接收特定 SIB的具体实现方式进行说明。
其中, 网络侧的处理过程可以描述为:
每个特定 SIB的重复周期内, 基站在该重复周期中系统帧号为 L+l ~ L+M 的 M个无线帧上, 重复发送用于调度特定 SIB的 PDCCH, 并重复发送特定 SIB。 其中, 重复周期中的其他 SIB在系统帧号为 L的无线帧中结束调度。 应当指出 的是, 此处的 SFN是无线帧在重复周期中的相对位置。
具体的, 基站在这 M个无线帧中, SIB1传输所在的子帧和 MBSFN传输所 在的子帧之外的各个子帧上, 调度特定 SIB的 PDCCH, 这些子帧上传输的 PDCCH的 DCI相同。 并在这些子帧上, 在 PDCCH调度的时频资源上发送特定 SIB。
如果特定 SIB的重复周期的长度是基站确定的, 则基站还在 SIB1中携带特 定 SIB的重复周期的长度。
如果 M的取值是基站确定的, 则基站还在 SIB1中携带 M的取值。 终端测的处理过程可以描述为:
每个特定 SIB的重复周期内, 终端在该重复周期中系统帧号为 L+l ~ L+M 的 M个无线帧上, 重复接收用于调度特定 SIB的 PDCCH, 并重复接收特定 SIB 对应的下行信号。应当指出的是, 此处的 SFN是无线帧在重复周期中的相对位 置。
具体的, 终端在这 M个无线帧中, SIB1传输所在的子帧和 MBSFN传输所 在的子帧之外的各个子帧上,接收调度特定 SIB的 PDCCH,这些子帧上传输的 PDCCH的 DCI相同。 通过合并接收到的信号正确解调出 PDCCH后, 从中获取 特定 SIB的调度信息。 当然, 如果通过合并部分子帧上接收到的信号就正确解 调出 PDCCH, 则后续不用继续接收 PDCCH。
在获取特定 SIB的调度信息后, 终端在这些子帧上, 在特定 SIB的调度信 息指示的时频资源上接收下行信号。 通过合并接收到的下行信号正确解调出 特定 SIB。 当然, 如果通过合并部分子帧上接收到的信号就正确解调出特定 SIB, 则后续不用继续在调度信息指示的时频资源上继续接收下行信号。
如果 PDCCH先被正确解调, 将会出现的情况是, 终端在某个子帧上仅需 要接收特定 SIB对应的下行信号, 不需要接收 PDCCH。 那么, 终端可以根据之 前正确解调出的 PDCCH中携带的特定 SIB的调度信息,在该调度信息指示的时 频资源上接收下行信号。
如果特定 SIB对应的 SI周期的长度是基站确定的, 则终端还在 SIB1中获取 特定 SIB的重复周期的长度。
如果 M的取值是基站确定的, 则终端还在 SIB1中获取 M的取值。
以图 4所示的调度时机为例, 对网络侧发送特定 SIB, 以及终端接收特定 SIB的具体实现方式进行说明。
对于该实现方式, 协议会预先约定多个发送特定 SIB的发送时机 pattern, 该发送时机 pattern中规定发送特定 SIB的无线帧在特定 SIB的重复周期中的相 对位置, 也可以规定发送特定 SIB的子帧在无线帧中的编号和所述无线帧在特 定 SIB的重复周期中的相对位置。 如果发送时机 pattern中规定了发送特定 SIB的无线帧在特定 S IB的重复周 期中的相对位置, 则在这些无线帧中, 除 SIB1传输所在子帧和 MBSFN传输所 在子帧之外的各个子帧上传输特定 SIB。 对于 TDD系统, 传输特定 SIB的子帧 也不是上行子帧和特殊子帧。
其中, 网络侧的处理过程可以描述为:
基站从协议约定的发送特定 SIB的发送时机 pattern中选择一个发送时机 pattern (如图 4所示)。 在特定 SIB的每个重复周期内, 系统帧号为 2、 4、 6、 7 的无线帧上发送用于调度特定 SIB的 PDCCH, 并发送上述特定 SIB。
具体的, 如果选择的发送时机 pattern仅规定了 SI周期中发送特定 SIB的无 线帧编号。 则基站在系统帧号为 2、 4、 6、 7的无线帧中, 除 SIB1传输所在子 些子帧上传输的 PDCCH的 DCI相同, 并在这些子帧上, 在 PDCCH调度的时频 资源上发送特定 SIB。 对于 TDD系统, 传输特定 SIB的子帧也不是上行子帧和 特殊子帧。
如果选择的发送时机 pattern规定了发送特定 SIB的子帧在特定 SIB的重复 周期中的相对位置。 则基站在系统帧号为 2、 4、 6、 7的无线帧中规定的子帧 上发送调度特定 SIB的 PDCCH, 这些子帧上传输的 PDCCH的 DCI相同, 并在 这些子帧上, 在 PDCCH调度的时频资源上发送特定 SIB。
其中,选择发送时机 pattern的具体实现方式根据实际通信需求确定,例如, 选择的发送时机 pattern规定的发送特定 SIB的时机需要避开传输 SIB 1的子帧、 传输 MBSFN的子帧。 对于 TDD系统, 还需要避开上行子帧和特殊子帧。
进一步的, 在特定 SIB的每个重复周期内, 基站还将发送时机 pattern的选 择结果携带在 SIB1中发送给终端。该选择结果既可以是选择的发送时机 pattern 的具体内容, 也可以是选择的发送时机 pattern的标识或者编号。
如果特定 SIB的重复周期的长度是基站确定的, 则基站还在 SIB1中携带特 定 SIB对应的 SI周期的长度。
终端测的处理过程可以描述为: 终端在特定 SIB的每个重复周期内, 从接收到的 SIB1中获取发送 SIB的发 送时机的选择结果。 从协议约定的发送特定 SIB的发送时机 pattern中确定选择 结果指示的发送时机 pattern (如图 4所示)。 在特定 SIB的每个重复周期内, 系 统帧号为 2、 4、 6、 7的无线帧上接收用于调度特定 SIB的 PDCCH, 并接收上述 特定 SIB。
具体的, 如果确定的发送时机 pattern规定了发送特定 SIB的无线帧在特定 SIB的重复周期中的相对位置。 则终端在系统帧号为 2、 4、 6、 7的无线帧中, 除 SIB1传输所在子帧和 MBSFN传输所在子帧之外的各个子帧上接收调度特 定 SIB的 PDCCH, 这些子帧上传输的 PDCCH的 DCI相同。 通过合并接收到的 信号正确解调出 PDCCH后, 从中获取特定 SIB的调度信息。 当然, 如果通过合 并部分子帧上接收到的信号就正确解调出 PDCCH , 则后续不用继续接收 PDCCH。 在获取特定 SIB的调度信息后, 终端在这些子帧上, 在特定 SIB的调 度信息指示的时频资源上接收下行信号。 通过合并接收到的下行信号正确解 调出特定 SIB。 当然, 如果通过合并部分子帧上接收到的信号就正确解调出特 定 SIB, 则后续不用继续在调度信息指示的时频资源上继续接收下行信号。 对 于 TDD系统, 传输特定 SIB的子帧也不是上行子帧和特殊子帧。
如果确定的发送时机 pattern规定了发送特定 SIB的子帧在无线帧中的编号 和所述无线帧在特定 SIB的重复周期中的相对位置。则基站在系统帧号为 2、 4、 6、 7的无线帧中规定的子帧上接收调度特定 SIB的 PDCCH,这些子帧上传输的 PDCCH的 DCI相同。 通过合并接收到的信号正确解调出 PDCCH后 , 从中获取 特定 SIB的调度信息。 当然, 如果通过合并部分子帧上接收到的信号就正确解 调出 PDCCH, 则后续不用继续接收 PDCCH。
在获取特定 SIB的调度信息后, 终端在这些子帧上, 在特定 SIB的调度信 息指示的时频资源上接收下行信号。 通过合并接收到的下行信号正确解调出 特定 SIB。 当然, 如果通过合并部分子帧上接收到的信号就正确解调出特定 SIB, 则后续不用继续在调度信息指示的时频资源上继续接收下行信号。
如果特定 SIB的重复周期的长度是基站确定的, 则终端还从 SIB1中获取特 定 SIB的重复周期的长度。
基于与方法同样的发明构思,如图 6所示,本发明实施例还提供一种基站, 包括:
调度信息发送模块 601 , 用于在特定 SIB的每个重复周期内, 重复发送所 述特定 SIB的调度信息;
SIB发送模块 602, 用于在特定 SIB的每个重复周期内, 在所述特定 SIB的 调度时机重复发送所述特定 SIB, 所述特定 SIB为终端进行通信所需的 SIB。

基于一种调度时机, 所述 SIB发送模块 602具体可以用于:
在特定 SIB的每个重复周期的连续 M个无线帧中, 重复发送所述特定 SIB。 较佳地, 所述 SIB发送模块 602具体用于:

基于上述调度时机的任意实现方式, 所述连续 M个无线帧的起始无线帧, 与所述特定 SIB的每个重复周期中调度其他 SIB的最后一个无线帧相邻; 或者, 所述连续 M个无线帧为所述重复周期的最后 M个无线帧。
基于另一种实现方式, 所述 SIB发送模块 602具体可以用于:
从预先约定的发送所述特定 SIB的发送时机图样中选择一个发送时机图 样, 发送所述特定 SIB的发送时机图样规定了发送所述特定 SIB的无线帧在特 定 SIB的重复周期中的相对位置, 或者, 发送所述特定 SIB的发送时机图样规 定了发送所述特定 SIB的子帧在无线帧中的编号和所述无线帧在特定 SIB的重 复周期中的相对位置;
在特定 SIB对应的每个重复周期内, 按照选择的发送时机图样重复发送所 述特定 SIB;
在特定 SIB对应的每个重复周期内, 将发送时机图样的选择结果携带在 SIB1中发送给所述终端。
基于上述任意基站实施例,较佳地,所述调度信息发送模块 601具体用于: 特定 SIB的每个重复周期内, 在发送所述特定 SIB的子帧上发送用于调度 所述特定 SIB的物理下行控制信道 PDCCH, 且每个 PDCCH携带的 DCI相同。
基于与方法同样的发明构思,如图 7所示,本发明实施例还提供一种终端, 包括:
调度信息接收模块 701, 用于在特定 SIB的每个重复周期内, 重复接收所 述特定 SIB的调度信息, 所述特定 SIB为终端进行通信所需的 SIB;
SIB接收模块 702, 用于获取所述特定 SIB的调度信息后, 在特定 SIB的每 个重复周期内, 在所述特定 SIB的调度时机重复接收下行信号, 以根据接收到 的下行信号获取所述特定 SIB
由于终端可以在一个重复周期内特定 SIB的调度时机重复接收下行信号, 如果重复次数足够多, 则可以合并一个重复周期内接收到的下行信号从而正 确解调出该特定 SIB。 即使无法在一个重复周期内正确解调出该特定 SIB , 由 于在重复周期内重复发送特定 SIB , 那么, 在一个 SIB修改周期内重复的次数 也较之现有技术至少增加一倍, 从而能够满足终端的解调需求, 提高系统性 基于一种调度时机, 所述 SIB接收模块 702具体可以用于:
