图 5为本发明实施例五所提供的下行信号传输装置 500的结构示意图； 图 6为本发明实施例六所提供的下行信号传输装置 600的结构示意图。 具体实施方式 为使本发明实施例的目的、 技术方案和优点更加清楚， 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 得的所有其他实施例， 都属于本发明保护的范围。
图 1为本发明实施例一所提供的下行信号传输方法的流程图。 本实施例 的方法适用于在 LTE-FDD系统中利用上行资源传输下行信号的情况。该方法 由下行信号传输装置执行， 该装置通常以硬件和 /或软件的方式来实现。 本实 施例的方法包括如下歩骤：
110、在第一时刻且在下行载波频段上向小站或第一用户设备发送下行调 度信令或半静态信令， 其中， 下行调度信令或半静态信令用于调度第一子帧 集合或第二子帧集合， 用于调度第一子帧集合的信令中包含第一指示信息， 第一指示信息用于指示小站或第一用户设备在第二时刻且在上行载波频段上 接收下行信号， 第一指示信息通过载波标识符 CIF字段占用的比特位表示， 用于调度第二子帧集合的信令用于调度传输下行信号的下行载波频段。
120、在第二时刻且在上行载波频段上向小站或第一用户设备发送下行信 号， 以使小站或第一用户设备根据接收的下行调度信令或半静态信令在第二 时刻且在上行载波频段上接收下行信号。
由于现有技术中是通过下行载波频段向小站或第一用户设备发送下行信 号， 不能充分利用上行载波频段资源， 120 中通过在第二时刻且在上行载波 频段上向小站或第一用户设备发送下行信号， 并通过在第一时刻且在下行载 波频段上向小站或第一用户设备发送的下行调度信令或半静态信令中包含的 第一指示信息指示小站或第一用户设备在第二时刻且在上行载波频段上接收 下行信号， 因此充分利用了上行频段的资源， 并保证了控制信道和数据信道 的数据的有效传输。
具体而言， 在第一时刻且在下行载波频段上向小站或第一用户设备发送 下行调度信令或半静态信令， 其中， 下行调度信令或半静态信令用于调度第 一子帧集合或第二子帧集合， 用于调度第一子帧集合的信令中包含第一指示 信息， 第一指示信息用于指示小站或第一用户设备在第二时刻且在上行载波 频段上接收下行信号， 第一指示信息通过载波标识符 CIF字段占用的比特位 表示，用于调度第二子帧集合的信令用于调度传输下行信号的下行载波频段， 在第二时刻且在上行载波频段上向小站或第一用户设备发送下行信号， 以使 小站或第一用户设备根据接收的下行调度信令或半静态信令在第二时刻且在 上行载波频段上接收下行信号， 其中， 第二时刻与第一时刻的时间差为 i毫 秒， i为大于等于 0的整数。
本实施例提供的下行信号传输方法， 通过在第一时刻且在下行载波频段 上向小站或第一用户设备发送下行调度信令或半静态信令， 其中， 下行调度 信令或半静态信令用于调度第一子帧集合和第二子帧集合， 用于调度第一子 帧集合的信令中包含用于指示小站或第一用户设备在第二时刻且在上行载波 频段上接收下行信号的第一指示信息， 并且在第二时刻且在上行载波频段上 向小站或第一用户设备发送下行信号， 从而解决了上行资源利用率较低的问 题， 提高了上行资源的利用率， 并能够确保控制信道和数据信道上的数据的 有效传输。
图 2为本发明实施例二所提供的下行信号传输方法的流程图。 参照图 2， 本实施例的方法可以包括：
210、接收基站在第一时刻且在下行载波频段上发送的下行调度信令或半 静态信令， 其中， 下行调度信令或半静态信令用于调度第一子帧集合或第二 子帧集合， 用于调度第一子帧集合的信令中包含第一指示信息， 第一指示信 息用于指示小站或第一用户设备在第二时刻且在上行载波频段上接收基站发 送的下行信号， 第一指示信息通过载波标识符 CIF字段占用的比特位表示， 用于调度第二子帧集合的信令用于调度传输下行信号的下行载波频段。
220、根据接收的下行调度信令或半静态信令， 在第二时刻且在上行载波 频段上接收基站在第二时刻且在上行载波频段上发送的下行信号。
由于现有技术中小站或第一用户设备接收到下行调度信令或半静态信令 后， 只能是根据接收的下行调度信令或半静态信令发送下行信号， 在下行载 波频段上接收下行信号， 因此不能充分利用上行载波频段资源， 220 中通过 根据接收的下行调度信令或半静态信令， 下行调度信令或半静态信令用于调 度第一子帧集合和第二子帧集合， 其中， 用于调度第一子帧集合的信令中包 含第一指示信息， 通过第一指示信息指示小站或第一用户设备在第二时刻且 在上行载波频段上接收基站发送的下行信号， 充分利用了上行频段的资源， 并保证了控制信道和数据信道的数据的有效传输。
具体而言， 接收基站在第一时刻且在下行载波频段上发送的下行调度信 令或半静态信令， 根据接收的下行调度信令或半静态信令， 在第二时刻且在 上行载波频段上接收基站在第二时刻且在上行载波频段上发送的下行信号。
本实施例提供的下行信号传输方法， 通过接收基站在第一时刻且在下行 载波频段上发送的下行调度信令或半静态信令， 根据接收的下行调度信令或 半静态信令， 在第二时刻且在上行载波频段上接收基站在第二时刻且在上行 载波频段上发送的下行信号， 从而提高了上行资源的利用率， 并能够确保控 制信道和数据信道上的数据的有效传输。
图 3为本发明实施例三所提供的下行信号传输方法的流程图。 本实施例 中以宏基站在第三时刻向小站覆盖范围内的第二用户设备发送上行调度信 令， 以及在第一时刻向第一用户设备发送下行调度信令和下行信号为例介绍 下行信号传输方法。 并且由于宏基站在第二时刻向第一用户设备发送下行信 号时小站也会收到宏基站发送的下行信号， 对于小站而言， 其接收的宏基站 在第二时刻且在上行载波频段上发送的下行信号对于其接收的第二用户设备 发送的上行信号为干扰信号， 因此小站可以进行干扰删除 (Interference Cancellation, 简称 IC)来增强接收性能， 即将接收的宏基站发送的下行信号删 除来增强接收性能。 参照图 3， 本实施例的方法可以包括：
301、宏基站在第三时刻向小站覆盖范围内的第二用户设备发送上行调度 信令。
宏基站在第三时刻向小站覆盖范围内的第二用户设备发送上行调度信 令， 以使第二用户设备根据上行调度信令在第二时刻且在上行载波频段上向 小站发送上行信号， 第二时刻与第三时刻的时间差为 j毫秒， j为正整数。
302、第二用户设备根据上行调度信令在第二时刻且在上行载波频段上向 小站发送上行信号， 第二时刻与第一时刻的时间差为 i毫秒， i为大于等于 0 的整数。
第二用户设备根据接收的上行调度信令在第二时刻且在上行载波频段上 采用下行信号格式向小站发送上行信号， 或， 第二用户设备根据接收的上行 调度信令在第二时刻且在上行载波频段上采用上行信号格式向小站发送上行 信号。 需要说明的是， 若第二用户设备在第二时刻且在上行载波频段上采用 下行信号格式向小站发送上行信号， 则小站在第二时刻且在上行载波频段上 采用下行信号格式接收第二用户设备发送的上行信号； 若第二用户设备在第 二时刻且在上行载波频段上采用上行信号格式向小站发送上行信号， 则小站 在第二时刻且在上行载波频段上采用上行信号格式接收第二用户设备发送的 上行信号。
303、 宏基站向第一用户设备发送上下行子帧配比。
宏基站向第一用户设备发送上下行子帧配比， 以使第一用户设备根据接 收的上下行子帧配比接收宏基站发送的下行信号， 或以使第一用户设备根据 接收的上下行子帧配比向宏基站发送上行信号。
304、 宏基站向第一用户设备发送第一控制消息。
宏基站可以打掉在第二时刻且在上行载波频段上发送的下行信号的最后 一个或两个符号后再向第一用户设备发送下行信号， 并且宏基站可以向第一 用户设备发送第一控制消息， 以使第一用户设备根据接收的第一控制消息打 掉在第二时刻且在上行载波频段上接收的宏基站发送的下行信号的最后一个 或两个符号来实现同歩。
需要说明的是， 宏基站通过打掉在第二时刻且在上行载波频段上发送的 下行信号的最后一个或两个符号后再向第一用户设备发送下行信号， 也可以 避免探测参考信号受到宏基站发送的下行信号的干扰， 例如， 由于宏基站可 以调度第一用户设备周期性发送探测参考信号来测量上行信道质量， 因此有 可能发生原本被用作传输探测参考信号的上行载波被宏基站用来传输下行信 号， 而使第一用户设备没有可利用的资源来发送探测参考信号的情况， 为避 免此种情况发生， 宏基站可以打掉在第二时刻且在上行载波频段上发送的下 行信号的最后一个或两个符号后再向第一用户设备发送下行信号， 即令最后 的 1个或 2个符号不传输数据， 避免影响信道质量的测量以及数据接收。
305、宏基站在第一时刻且在下行载波频段上向其覆盖范围内的第一用户 设备发送下行调度信令或半静态信令。
其中， 下行调度信令或半静态信令用于调度第一子帧集合或第二子帧集 合， 用于调度第一子帧集合的信令中包含第一指示信息， 第一指示信息用于 指示小站或第一用户设备在第二时刻且在上行载波频段上接收下行信号， 第 一指示信息通过载波标识符 CIF字段占用的比特位表示， 用于调度第二子帧 集合的信令用于调度传输下行信号的下行载波频段， 第二时刻与第一时刻的 时间差为 i毫秒， i为大于等于 0的整数。 例如， 目前 CIF信息占用 3比特共 可以指示 8个状态， 当前已采用其中 5个状态用于载波聚合， 因此可使用剩 余的状态来表示第一指示信息。 并且， 由于宏基站在第二时刻且在上行载波 频段上向第一用户设备发送下行信号的模式下上行链路、 下行链路分别采用 单层传输， 因此下行调度信令或半静态信令中还可以包含通过复用第二层的 解调和编码调制方案 MCS字段携带的下行信号采用的 MCS。 并且， 下行调 度信令或半静态信令中还可以包含通过复用解调参考信号信息字段携带的下 行信号采用的解调信息。
需要说明的是， 宏基站在第二时刻且在上行载波频段上向第一用户设备 发送下行信号可以通过如下方式实现：
宏基站在第二时刻且在上行载波频段上采用下行信号格式向第一用户设 备发送下行信号或在第二时刻且在上行载波频段上采用上行信号格式向第一 用户设备发送下行信号。 需要说明的是， 若宏基站在第二时刻且在上行载波 频段上采用下行信号格式向第一用户设备发送下行信号， 则第一用户设备在 第二时刻且在上行载波频段上采用下行信号格式接收宏基站发送的下行信 号； 若宏基站在第二时刻且在上行载波频段上采用上行信号格式向第一用户 设备发送下行信号， 则第一用户设备在第二时刻且在上行载波频段上采用上 行信号格式接收宏基站发送的下行信号。
306、 在第二时刻且在上行载波频段上向第一用户设备发送下行信号。 需要说明的是， 由于 306中宏基站向第一用户设备发送下行信号时， 其 覆盖范围内的小站也会接收到宏基站发送的下行信号， 如图 3中示出的， 通 过用宏基站和小站之间的虚线来表示宏基站向第一用户设备发送下行信号 时， 宏基站覆盖范围内的小站也接收到了宏基站发送的下行信号。
307、 宏基站向第一用户设备发送第二控制消息。
宏基站向第一用户设备发送第二控制消息， 以使第一用户设备根据接收 的第二控制消息在当前待传输确认消息的上行载波频段上偏移一个时间偏移 值后发送确认消息， 确认消息中包含用于指示下行信号是否被第一用户设备 正确接收的第二指示信息。
由于第一用户设备是否成功接收下行信号， 会在上行信号中相应反馈确 认 /否定性确认 ( Acknowledgement/Negative Acknowledgement， 简禾尔 ACK/NACK) 信息给宏基站， 本实施例中由于采用在上行载波频段上发送下 行信号， 可能导致原本用来传输 ACK/NACK信息的上行载波被占用， 导致 没有资源发送 ACK/NACK信息的情况发生。 为避免出现该情况， 宏基站通 过第二控制消息通知第一用户设备一个时间偏移值， 第一用户设备在目前待 传输 ACK/NACK 信息的资源上偏移一个时间偏移值后再向宏基站传输 ACK/NACK信息，或宏基站直接通知第一用户设备在特定的资源上向宏基站 发送 ACK/NACK信息。
308、宏基站接收第一用户设备发送的确认消息， 确认消息中包含第一指 示信息， 第一指示信息用于指示宏基站发送的下行信号是否被第一用户设备 正确接收。
309、 宏基站向第一用户设备发送第三控制消息。
宏基站向第一用户设备发送第三控制消息， 以使第一用户设备根据第三 控制消息向宏基站周期上报信道质量指示 CQI, 第三控制消息中包含设定的 用于指示第一用户设备上报 CQI的周期信息， 以使第一用户设备根据 CQI的 周期信息周期上报 CQI。 本实施例中由于采用在上行载波频段上发送下行信 号的传输模式， 为该传输模式预留的资源的周期为 8个子帧， 便于尽量维持 后向兼容性， 避免对物理上行控制信道（Physical Uplink Control Channel, 简 称： PUCCH) 的影响。 例如， 对于 PUCCH格式 2和 3， 可以通过设置第一 用户设备的 CQI的上报周期避开使用发送下行信号的上行载波来传输 CQI。
310、 第一用户设备根据第三控制消息向宏基站周期上报信道质量指示。 第一用户设备接收宏基站发送的第三控制消息， 第三控制消息中包含设 定的用于指示第一用户设备上报信道质量指示 CQI的周期信息， 并根据 CQI 的周期信息向宏基站周期上报 CQI。
通过 301〜310， 宏基站可以利用本站空闲的 FDD的上行载波来发送下行 信号， 调度第一用户设备在第二时刻且在上行载波频段上接收宏基站发送的 下行信号， 并且通过在第三时刻调度第二用户设备在上行载波频段上向小站 发送上行信号。 由于小站在第二时刻接收到了第二用户设备根据在第三时刻 收到的上行调度信令在第二时刻发送的上行信号， 并且由于小站在第二时刻 也接收到了宏基站发送的下行信号， 因此对于小站而言， 其接收的宏基站发 送的下行信号对于其接收的第二用户设备发送的上行信号而言为干扰信号， 因此小站可以进行 IC来增强接收性能，即将接收的宏基站发送的下行信号删 除来增强接收性能。
本实施例提供的下行信号传输方法， 通过在第三时刻向小站覆盖范围内 的第二用户设备发送上行调度信令， 在第一时刻且在下行载波频段上向第一 用户设备发送下行调度信令或半静态信令， 并且在第二时刻且在上行载波频 段上向第一用户设备发送下行信号，从而解决了上行资源利用率较低的问题， 提高了上行资源的利用率， 并能够确保控制信道和数据信道上的数据的有效 传输，而且小站可以通过删除接收的宏基站发送的下行信号来增强接收性能。
图 4为本发明实施例四所提供的下行信号传输方法的流程图。 本实施例 中以宏基站在第三时刻向小站覆盖范围内的第二用户设备发送上行调度信 令， 并在第一时刻向小站发送下行调度信令且在第二时刻向小站发送下行信 号为例介绍下行信号传输方法。从而实现小站的多输入多输出（Multiple Input Multiple Output, 简称 MIMO) 性能。 参照图 4， 本实施例的方法可以包括： 401、宏基站在第三时刻向小站覆盖范围内的第二用户设备发送上行调度 信令。
宏基站在第三时刻向小站覆盖范围内的第二用户设备发送上行调度信 令， 以使第二用户设备根据上行调度信令在第二时刻且在上行载波频段上向 小站发送上行信号， 第三时刻与第一时刻的时间差为 j毫秒， j为正整数。
402、第二用户设备根据上行调度信令在第二时刻且在上行载波频段上向 小站发送上行信号。
第二用户设备根据上行调度信令在第二时刻且在上行载波频段上采用下 行信号格式向小站发送上行信号， 或， 第二用户设备根据上行调度信令在第 二时刻且在上行载波频段上采用上行信号格式向小站发送上行信号。 需要说 明的是， 若第二用户设备在第二时刻且在上行载波频段上采用下行信号格式 向小站发送上行信号， 则小站在第二时刻且在上行载波频段上采用下行信号 格式接收第二用户设备发送的上行信号； 若第二用户设备在第二时刻且在上 行载波频段上采用上行信号格式向小站发送上行信号， 则小站在第二时刻且 在上行载波频段上采用上行信号格式接收第二用户设备发送的上行信号。
403、 宏基站向小站发送上下行子帧配比。
宏基站向小站发送上下行子帧配比， 以使小站根据上下行子帧配比接收 宏基站发送的下行信号或以使小站根据上下行子帧配比向宏基站发送上行信 号。
404、 宏基站向小站发送第一控制消息。
宏基站可以打掉在第二时刻且在上行载波频段上发送的下行信号的最后 一个或两个符号后再向小站发送下行信号， 并且宏基站向小站发送第一控制 消息， 以使小站根据接收的第一控制消息打掉在第二时刻且在上行载波频段 上接收的宏基站发送的下行信号的最后一个或两个符号来实现同歩。
需要说明的是， 宏基站通过打掉在第二时刻且在上行载波频段上发送的 下行信号的最后一个或两个符号后再向小站发送下行信号， 也可以避免探测 参考信号受到宏基站发送的下行信号的干扰， 例如， 由于宏基站可以调度小 站周期性发送探测参考信号来测量上行信道质量， 因此有可能发生原本被用 作传输探测参考信号的上行载波被宏基站用来传输下行信号， 而使小站没有 可利用的资源来发送探测参考信号的情况， 为避免此种情况发生， 宏基站可 以打掉在第二时刻且在上行载波频段上发送的下行信号的最后一个或两个符 号后再向小站发送下行信号， 即令最后的 1个或 2个符号不传输数据， 避免 影响信道质量的测量以及数据接收。
405、宏基站在第一时刻且在下行载波频段上向其覆盖范围内的小站发送 下行调度信令或半静态信令。
其中， 下行调度信令或半静态信令用于调度第一子帧集合或第二子帧集 合， 用于调度第一子帧集合的信令中包含第一指示信息， 第一指示信息用于 指示小站在第二时刻且在上行载波频段上接收下行信号， 第一指示信息通过 载波标识符 CIF字段占用的比特位表示， 用于调度第二子帧集合的信令用于 调度传输下行信号的下行载波频段， 第二时刻与第一时刻的时间差为 i毫秒， i为大于等于 0的整数。例如，目前 CIF信息占用 3比特共可以指示 8个状态， 当前已采用其中 5个状态用于载波聚合， 因此可使用剩余的状态来表示第一 指示信息。 并且， 由于宏基站在第二时刻且在上行载波频段上向小站发送下 行信号的模式下上行链路、 下行链路分别采用单层传输， 因此下行调度信令 或半静态信令中还可以包含通过复用第二层的解调和编码调制方案 MCS 字 段携带的下行信号采用的 MCS。 并且， 下行调度信令或半静态信令中还可以 包含通过复用解调参考信号信息字段携带的下行信号采用的解调信息。
需要说明的是， 宏基站在第二时刻且在上行载波频段上向小站发送下行 信号可以通过如下方式是实现：
宏基站在第二时刻且在上行载波频段上采用下行信号格式向小站发送下 行信号或在第二时刻且在上行载波频段上采用上行信号格式向小站发送下行 信号。 需要说明的是， 若宏基站在第二时刻且在上行载波频段上采用下行信 号格式向小站发送下行信号， 则小站在第二时刻且在上行载波频段上采用下 行信号格式接收宏基站发送的下行信号； 若宏基站在第二时刻且在上行载波 频段上采用上行信号格式向小站发送下行信号， 则小站在第二时刻且在上行 载波频段上采用上行信号格式接收宏基站发送的下行信号。
406、 在第二时刻且在上行载波频段上向小站发送下行信号。
407、 宏基站向小站发送第二控制消息。
宏基站向小站发送第二控制消息， 以使小站根据接收的第二控制消息在 当前待传输确认消息的上行载波频段上偏移一个时间偏移值后发送确认消 息，确认消息中包含用于指示下行信号是否被小站正确接收的第二指示信息。 由于小站是否成功接收下行信号，会在上行信号中相应反馈 ACK/NACK 信息给宏基站， 本实施例中由于采用在上行载波频段上发送下行信号， 可能 导致原本用来传输 ACK/NACK信息的上行载波被占用， 导致没有资源发送 ACK/NACK信息的情况发生。为避免出现该情况， 宏基站通过第二控制消息 通知小站一个时间偏移值， 小站在目前待传输 ACK/NACK信息的资源上偏 移一个时间偏移值后再传输 ACK/NACK信息， 或宏基站直接通知小站在特 定的资源上发送 ACK/NACK信息。
408、 宏基站接收小站发送的确认消息， 确认消息中包含第一指示信息， 第一指示信息用于指示宏基站发送的下行信号是否被小站正确接收。
409、 宏基站向小站发送第三控制消息。
宏基站向小站发送第三控制消息， 以使小站根据接收的第三控制消息向 宏基站周期上报信道质量指示 CQI, 第三控制消息中包含设定的用于指示小 站上报 CQI的周期信息， 以使小站根据 CQI的周期信息周期上报 CQI。 本实 施例中由于采用在上行载波频段上发送下行信号的传输模式， 为该传输模式 预留的资源的周期为 8个子帧， 便于尽量维持后向兼容性， 避免对 PUCCH 的影响。 例如， 对于 PUCCH格式 2和 3， 可以通过设置小站的 CQI的上报 周期避开使用发送下行信号的上行载波来传输 CQI。
410、 小站根据接收的第三控制消息向宏基站周期上报信道质量指示。 小站接收宏基站发送的第三控制消息， 第三控制消息中包含设定的用于 指示小站上报信道质量指示 CQI的周期信息， 并根据第三控制消息向宏基站 周期上报 CQI。
通过 401〜410， 宏基站可以利用本站空闲的 FDD的上行载波来发送下行 信号，调度小站在第二时刻且在上行载波频段上接收宏基站发送的下行信号， 并且通过在第三时刻调度第二用户设备， 使第二用户设备根据上行调度信令 在第二时刻且在上行载波频段上向小站发送上行信号， 以实现小站的 MIMO 性能， 即小站在第二时刻可以同时接收到宏基站发送的下行信号和第二用户 设备发送的上行信号。
本实施例提供的下行信号传输方法， 通过在第三时刻向小站覆盖范围内 的第二用户设备发送上行调度信令， 在第一时刻且在下行载波频段上向小站 发送下行调度信令或半静态信令， 并且在第二时刻且在上行载波频段上向小 站发送下行信号， 从而解决了上行资源利用率较低的问题， 提高了上行资源 的利用率， 并能够确保控制信息和业务数据的有效传输， 而且还实现了小站 的 MIMO性能。
