如图 1所示,为了防止 FDD上行数据传输与 TDD下行数据传输之间的 干扰, 在 FDD上行频带与 TDD频带之间有一定宽度的保护带; 同样的, 为了防止 TDD上行数据传输与 FDD下行数据传输之间的干扰,在 TDD频 带与 FDD下行频带之间也有一定宽度的保护带。

为了给出在两个相邻频带中进行数据传输的实现方案, 本发明实施例 提供了一种确定辅载波传输方向的装置及方法, 以下结合说明书附图对本 发明的优选实施例进行说明, 应当理解, 此处所描述的优选实施例仅用于 说明和解释本发明, 并不用于限定本发明。 并且在不冲突的情况下, 本申 实施例一
图 3为本发明一种确定辅载波传输方向的装置实施例一结构示意图, 所述装置包括:
获取单元 301, 用于根据网络配置信息获取第一辅载波的参考载波。
所述第一辅载波与参考载波在相邻的两个频带中传输, 或者参考载波 与第一辅载波相邻的第二辅载波相同, 包括: 参考载波与第二辅载波的子 帧的传输方向配比相同, 以及参考载波与第二辅载波的子帧定时相同。 例 如网络配置了主载波, 第一辅载波, 第二辅载波, 其中第一辅载波, 第二 辅载波相邻, 并且主载波和第二辅载波的配比和子帧定时相同, 则此时参 考载波可以是第二辅载波, 也可以是主载波。
基站配置第一辅载波以及传输载波, 其中, 基站所配置的传输载波有 可能只包括主载波, 也有可能包括主载波以及至少一个第二辅载波。 参考 载波只有一个时, 参考载波有可能是主载波, 也有可能是一个第二辅载波; 当参考载波为两个时, 有可能是一个主载波以及一个第二辅载波, 也有可 能是两个第二辅载波, 根据实际情况进行设定。
预置的网络信息主要携带有根据第一辅载波所传输的频带所选定的参 考载波的标识。 所述预置的网络配置信息可以是基站预先配置的, 也可以 是移动终端预先配置的。 基站可以根据基站预先配置的预置的网络配置信 息获取第一辅载波的参考载波; 移动终端可以根据从基站所接收的预置的 网络配置信息或移动终端自身预先配置的预置的网络配置信息获取第一辅 载波的参考载波。
这里需要说明的是, 基站或移动终端一般依据下面原则预先设置网络 配置信息, 以第一辅载波为在 FDD与 TDD频带之间, 或 TDD中两个频带 之间的保护带中传输的载波为例:
当第一辅载波为在 FDD上行频带与 TDD频带之间的保护带中传输的 载波时,将 TDD频带上距离 FDD上行频带与 TDD频带之间的保护带最近 的载波作为参考载波;
当第一辅载波为在 FDD下行频带与 TDD频带之间的保护带中传输的 载波时,将 TDD频带上距离 FDD下行频带与 TDD频带之间的保护带最近 的载波作为参考载波;
当第一辅载波为在 TDD 频带中的两个频带之间的的保护带中传输的 载波时, 将保护带两边的两个 TDD频带作为参考载波。
这里需要说明的是, 第一辅载波还可以为在其他频带中传输的载波,
选择与第一辅载波在相邻频带中传输的载波作为参考载波即可。 确定单元 302, 用于根据所述参考载波中子帧的传输方向确定第一辅 载波中子帧的传输方向, 以使得参考载波与第一辅载波在同一时刻的数据 传输方向相同。
确定好参考载波后, 根据确定好的参考载波配置第一辅载波, 所述确 定单元 302有三种可能的结构:
第一种可能的结构, 所述第一辅载波为只传输上行数据的辅载波时,所 述确定单元 302包括:
第一确定子单元, 用于根据所述参考载波的上行传输子帧确定所述第 一辅载波的上行传输子帧;
或者,
第二确定子单元, 用于根据所述参考载波的特殊传输子帧中的上行传 输部分和 /或 GAP确定第一辅载波的特殊子帧的上行传输部分。
以所述第一辅载波为在频分双工 FDD上行频带与 TDD频带之间的保 护带中传输的载波为例进行说明:
FDD上行频带与 TDD频带之间的保护带中传输的第一辅载波只能在 TDD频带的参考载波进行上行数据传输时, 传输上行数据。 此时, FDD上 行频带,保护带以及距离保护带最近的参考载波所在的 TDD频带都进行上 行数据传输, 三者彼此之间不会产生干扰。
因此, 所述参考载波为距离 FDD上行频带与 TDD频带之间的保护带 最近的 TDD频带的载波。 如图 4所示, 所述参考载波为 TDD载波 1。 所 述参考载波为上行参考载波, 根据所述参考载波配置保护带辅载波的上行 数据传输部分。如图 5所示,参考载波与第一辅载波都是由 10个子帧组成, 参考载波中包括下行子帧、 上行子帧以及特殊子帧。
根据所述参考载波中子帧的传输方向确定第一辅载波中子帧的传输方 向包括:
对于正常子帧, 根据所述参考载波的上行传输子帧确定所述第一辅载 波的上行传输子帧。 如图 5所示, 参考载波的第 3子帧为上行传输子帧, 则配置第一辅载波的第 3子帧也为上行传输子帧。
对于特殊子帧, 根据所述参考载波的特殊传输子帧中的上行传输部分 和 /或 GAP 确定第一辅载波的特殊子帧的上行传输部分。 所述特殊子帧是 TDD 系统中上行转换的子帧, 所述特殊子帧包括一段下行传输符号 ( Downlink Pilot Time Slot, DWPTS ), 一段 GAP以及一段上行传输符号 ( Uplink Pilot Time Slot, UPPTS )。 如图 5所示, 参考载波的第 2子帧为 特殊子帧, 则第一辅载波的第 2子帧对应于参考载波中第 2子帧的 GAP和 上行传输符号的部分作为上行传输部分。 这里需要说明的是, 保护带辅载 波上与参考载波的 GAP对应的部分可以为上行传输部分,也可以为空白的 保护带。
在确定第一辅载波的子帧的传输方向时, 可以只根据所述参考载波的 上行传输子帧确定所述第一辅载波的上行传输子帧; 也可以根据所述参考 载波的特殊传输子帧中的上行传输部分和 /或 GAP 确定第一辅载波的特殊 子帧的上行传输部分; 还可以既根据所述参考载波的上行传输子帧确定所 述第一辅载波的上行传输子帧, 又根据所述参考载波的特殊传输子帧中的 上行传输部分和 /或 GAP 确定第一辅载波的特殊子帧的上行传输部分。 根 据具体需要进行具体设定, 这里不进行限定。
此时, 第一辅载波只有上行传输子帧, 其他的部分不进行数据传输, 即不接收数据, 也不发送数据。
第二种可能的结构, 所述第一辅载波为只传输下行数据的辅载波时, 所述确定单元 302包括:
第三确定子单元, 用于根据所述参考载波的下行传输子帧确定所述第 一辅载波的下行传输子帧;
和 /或,
第四确定子单元, 用于根据所述参考载波的特殊传输子帧中的下行传 输部分和 /或 GAP确定第一辅载波的特殊子帧的下行传输部分。
以所述第一辅载波为在频分双工 FDD下行频带与 TDD频带之间的保 护带中传输的载波为例进行说明:
FDD下行频带与 TDD频带之间的保护带中传输的第一辅载波只能在 TDD频带的参考载波进行下行数据传输时, 传输下行数据。 此时, FDD下
行频带, 保护带以及距离保护带最近的 TDD频带都进行下行数据传输, 三 者彼此之间不会产生干扰。
因此, 所述参考载波为距离 FDD下行频带与 TDD频带之间的保护带 最近的 TDD频带中所传输的载波。 如图 4所示, 所述参考载波为 TDD载 波 2。 所述参考载波为下行参考载波, 根据所述参考载波配置第一辅载波 的下行数据传输部分。 如图 6所示, 参考载波与第一辅载波都是由 10个子 帧组成, 参考载波中包括下行子帧、 上行子帧以及特殊子帧。 这里需要说 明的是, 当 TDD频带上只有一个主载波时, 上行参考载波与下行参考载波 都为 TDD频带上的主载波; 而当 TDD频带上有主载波以及至少一个 TDD 辅载波时, 上行参考载波一般与下行参考载波为不同的载波。 其中, 上行 参考载波为 FDD上行频带与 TDD频带之间的保护带辅载波的参考载波, 下行参考载波为 FDD下行频带与 TDD频带之间的保护带辅载波的参考载 波。
根据所述参考载波中子帧的传输方向确定第一辅载波中子帧的传输方 向包括:
对于正常子帧, 根据所述参考载波的下行传输子帧确定所述第一辅载 波的下行传输子帧。 如图 6所示, 参考载波的第 1子帧、 第 4子帧至第 10 子帧为下行传输子帧, 则确定第一辅载波的第 1子帧、 第 4子帧至第 10子 帧也为下行传输子帧。
对于特殊子帧, 根据所述参考载波的特殊传输子帧中的下行传输部分 和 /或 GAP确定第一辅载波的特殊子帧的下行传输部分。 如图 6所示, 参 考载波的第 2子帧为特殊子帧, 配置第一辅载波的第 2子帧对应于参考载 波中第 2子帧的 GAP和下行传输符号的部分作为下行传输部分。这里需要 说明的是, 第一辅载波上与参考载波的 GAP对应的部分可以为下行传输部 分, 也可以为空白的保护带。
在确定第一辅载波的子帧的传输方向时, 可以只根据所述参考载波的 下行传输子帧确定所述第一辅载波的下行传输子帧; 也可以根据所述参考 载波的特殊传输子帧中的下行传输部分和 /或 GAP 确定第一辅载波的特殊 子帧的下行传输部分; 还可以既根据所述参考载波的下行传输子帧确定所
述第一辅载波的下行传输子帧, 又根据所述参考载波的特殊传输子帧中的 下行传输部分和 /或 GAP 确定第一辅载波的特殊子帧的下行传输部分。 根 据具体需要进行具体设定, 这里不进行限定。
这里需要说明的是, 本实施例中所举的实例中, TDD载波 1 与 TDD 载波 2的子帧的传输方向上下配比相同, 并且子帧的定时也相同, 因此, 在预先设置网络配置信息时, 可以设置 TDD载波 1与 TDD载波 2任意一 个共同作为上行参考载波以及下行参考载波, 也可以设置 TDD载波 1 与 TDD载波 分别作为上行参考载波与下行参考载波。 但是当 TDD载波 1 与 TDD载波 2的上下配比关系不同时,则必须设置 TDD载波 1与 TDD载 波 2分别作为上行参考载波与下行参考载波。
此时, 第一辅载波只有下行传输子帧, 其他的部分不进行数据传输, 即不接收数据, 也不发送数据。
第三种可能的结构, 所述第一辅载波为既传输上行数据也传输下行数 据的辅载波时, 所述确定单元 302包括:
第五确定子单元、 第六确定子单元、 第七确定子单元以及第八确定子 单元任意一个或多个;
所述第五确定子单元, 用于当两个参考载波的第一位置的子帧都是上 行传输子帧时, 确定第一辅载波中第一位置的子帧为上行传输子帧;
所述第六确定子单元, 用于当两个参考载波的第二位置的子帧都是下 行传输子帧时, 确定第一辅载波中第二位置的子帧为下行传输子帧;
所述第七确定子单元, 用于当两个参考载波的第三位置的子帧有一个 特殊子帧时, 根据两个参考载波第三位置的子帧中都是上行传输部分和 /或 GAP确定第一辅载波中第三位置的子帧中的上行传输部分;
所述第八确定子单元, 用于当两个参考载波的第三位置的子帧有一个 特殊子帧时, 根据两个参考载波第三位置的子帧中都是下行传输部分和 /或 GAP确定第一辅载波中第三位置的子帧中的上行传输部分。
以所述第一辅载波为在 TDD 频带中的两个频带之间的的保护带中传 输的载波为例:
T D D频带中两个频带之间的保护带中传播的第一辅载波只能在两个频
此时, TDD 的两个频带以及两个频带之间的保护带都进行相同方向的数据传输, 三者 彼此之间不会产生干扰。
因此, 所述两个参考载波为保护带两边相邻的两个 TDD载波。 如图 7 所示, 所述两个参考载波为 TDD载波 3和 TDD载波 4。 如图 8所示, 两 个参考载波与第一辅载波都是由 10 个子帧组成, 参考载波中包括下行子 帧、 上行子帧以及特殊子帧, 两个参考载波分别为保护带两边与保护带相 邻的两个 TDD载波。
根据根据所述参考载波中子帧的传输方向确定第一辅载波中子帧的传 输方向包括:
对于正常子帧, 当两个参考载波的第一位置的子帧都是上行传输子帧 时, 确定第一辅载波中第一位置的子帧为上行传输子帧。 如图 8所示, 两 个参考载波的第 3子帧都为上行传输子帧, 确定第一辅载波的第 3子帧也 为上行传输子帧。 其中, 第一位置是泛指, 指的是两个参考载波对应位置 都是上行传输子帧时, 上行传输子帧所在参考载波的位置。 如图 8所示, 第一位置为两个参考载波第 3子帧的位置。
对于正常子帧, 当两个参考载波的第二位置的子帧都是下行传输子帧 时, 确定第一辅载波中第二位置的子帧为下行传输子帧。 如图 8所示, 两 个参考载波的第 1子帧、 第 5子帧、 第 6子帧以及第 10子帧都为下行传输 子帧, 确定第一辅载波的第 1子帧、 第 5子帧、 第 6子帧以及第 10子帧也 为下行传输子帧。 其中, 第二位置是泛指, 指的是两个参考载波对应位置 都是下行传输子帧时, 下行传输子帧所在参考载波的位置。 如图 8所示, 两个参考载波第 1子帧、 第 5子帧、 第 6子帧以及第 10子帧的位置都为第 二位置。
对于特殊子帧, 当两个参考载波的第三位置的子帧有一个特殊子帧时, 根据两个参考载波第三位置的子帧中都是上行传输部分和 /或 GAP 确定第 一辅载波中第三位置的子帧中的上行传输部分。 如图 8所示, 参考载波 1 的第 2子帧和第 7子帧, 参考载波 2的第 2子帧都为特殊子帧。 对于参考 载波 1的第 2子帧以及参考载波 2的第 2子帧, 确定第一辅载波的第 2子
帧的上行传输部分对应于参考载波 1的第 2子帧与参考载波 2的第 2子帧 中较短的上行传输符号部分。 确定第一辅载波的第 2子帧的上行传输部分 对应于参考载波 1的第 2子帧中上行传输符号部分。
这里需要说明的是, 对于参考载波 1的第 2子帧中的 GAP, 第一辅载 波其对应的部分可以配置为 GAP, 也可以配置为上行传输部分。 对于参考 载波 2第 2子帧中的 GAP, 保护带辅载波其对应的部分可以配置为 GAP, 也可以配置为下行传输部分。
对于参考载波 1的第 7特殊子帧, 参考载波 2的第 7子帧为下行传输 子帧, 确定第一辅载波的第 7子帧的下行传输部分对应于参考载波 1的第 7子帧与参考载波 2的第 7子帧中较短的下行传输符号部分。 如图 8所示, 参考载波 1的第 7子帧中下行传输符号分比参考载波 2的第 7子帧中下行 传输符号部分短, 确定第一辅载波的第 7子帧的下行传输部分与参考载波 1的第 7子帧中下行传输符号部分相同。
此时, 第一辅载波既有上行传输子帧, 也有下行传输子帧。 对于两个 参考载波的第四位置的子帧的传输方向不同的时, 第一辅载波的第四位置 不进行数据传输, 即不接收数据, 也不发送数据。
这里需要说明的是, 对于参考载波 1第 7子帧中的 GAP, 保护带辅载 波其对应的部分可以配置为 GAP, 也可以配置为下行传输部分。 第一辅载 波其他的部分, 由于参考载波 1和参考载波 2所对应的子帧的传输方向不 同, 作为保护带隔离参考载波 1 和参考载波 2, 不进行数据传输。 配置好 的保护带辅载波如图 8所示。
由上述内容可知, 本发明实施例具有以下有益效果:
根据网络配置信息获取第一辅载波的参考载波, 根据所述参考载波中 子帧的传输方向确定第一辅载波中子帧的传输方向, 以使得参考载波与第 一辅载波在同一时刻的数据传输方向相同。 利用参考载波确定与其在相邻 频带中传输的第一辅载波的子帧的数据的传输方向, 保证参考载波和第一 辅载波中同时有数据传输时, 数据传输方向相同, 避免相邻频带同时传输 不同方向的数据时产生干扰。

如图 6所示, 确定所述第一辅载波的下行数据传输部分与所述参考载 波的下行数据传输部分和 GAP的边界相同, 当然, 也可以仅确定所述第一
辅载波的下行数据传输部分与所述参考载波的下行数据传输部分的边界相 同。 由于所述参考载波除下行传输子帧和间隙 GAP以外, 其他部分进行上 行数据传输, 此时, 为了避免 FDD下行频带与参考载波之间的干扰, 保护 带不进行数据传输。 配置好的第一辅载波如图 6所示。
如图 8所示, 参考载波 1的第 2子帧中上行传输符号分比参考载波 2 的第 2子帧中上行传输符号部分短, 确定所述第一辅载波的第 2子帧的上 行传输部分与参考载波 1的第 2子帧中上行传输符号分的边界相同。 参考 载波 2的第 2子帧中下行传输符号分比参考载波 1的第 2子帧中下行传输 符号部分短, 确定第一辅载波的第 2子帧的下行传输部分与参考载波 2的 第 2子帧中下行传输符号分的边界相同。 参考载波 1的第 7子帧中下行传 输符号分比参考载波 2的第 7子帧中下行传输符号部分短, 确定第一辅载 波的第 7子帧的下行传输部分与参考载波 1的第 7子帧中下行传输符号分 的边界相同。

如图 5所示, 考载波的第 3子帧为上行传输子帧, 确定第一辅载波的 第 3子帧也为上行传输子帧。 参考载波的第 3子帧的序号为 2, 则确定第 一辅载波的中与所述参考载波的第 3子帧对应的子帧序号为 2。
如图 6所示, 参考载波的第 1子帧、 第 4子帧至第 10子帧为下行传输 子帧, 则确定第一辅载波的第 1子帧、 第 4子帧至第 10子帧也为下行传输 子帧。 参考载波的第 1 子帧序号为 0, 确定第一辅载波上与所述参考载波 的第 1子帧对应的子帧序号也为 0; 参考载波的第 4子帧序号为 3, 确定第 一辅载波上与所述参考载波的第 4子帧对应的子帧序号也为 3; 参考载波 的第 5子帧序号为 4, 确定第一辅载波上与所述参考载波的第 5子帧对应 的子帧序号也为 4; 参考载波的第 6子帧序号为 5, 确定第一辅载波上与所 述参考载波的第 6子帧对应的子帧序号也为 5; 参考载波的第 7子帧序号 为 6,确定第一辅载波上与所述参考载波的第 7子帧对应的子帧序号也为 6;

数据传输装置 905, 用于利用所述第一辅载波进行数据的上行传输和 / 或下行接收。
所述数据传输装置 905有三种可能的结构:
第一种可能的结构, 所述第一辅载波为只传输上行数据的辅载波时: 第一监测单元, 用于从传输载波监测针对第一辅载波的 PDCCH调度 信息, 所述 PDCCH调度信息包括 PDCCH格式 0、 PDCCH格式 3 以及 PDCCH格式 3A中的任意一种或多种;
第一传输单元, 用于根据所述 PDCCH调度信息利用所述第一辅载波 传输上行数据。
当第一辅载波只传输上行数据时, 第一辅载波中只有上行传输子帧, 移动终端只监测针对第一辅载波的上行数据传输调度信息。 则移动终端只 监测 PDCCH格式 0、 PDCCH格式 3以及 PDCCH格式 3A的 PDCCH调度 信息, 忽略 PDCCH格式 1, PDCCH格式 1A, PDCCH格式 1B, PDCCH 格式 1C, PDCCH格式 ID, PDCCH格式 2,以及 PDCCH格式 2 A的 PDCCH
调度信息, 减少盲检测 PDCCH调度信息的格式数量, 移动终端可以加快 针对第一辅载波的 PDCCH信息的处理。
其中, PDCCH格式 0或 PDCCH格式 3以及 PDCCH格式 3 A的 PDCCH 调度信息是由基站通过传输载波中的下行传输子帧发送至移动终端, 所述 传输载波为 TDD频带中的下行传输子帧中传输的载波或 FDD下行频带中 传输的载波。 移动终端根据所述 PDCCH调度信息利用所述第一辅载波向 基站传输上行数据。 并且所述移动终端不执行对针对第一辅载波的任何下 行信号的搜索和或测量。
第二种可能的结构, 所述第一辅载波为只传输下行数据的辅载波时: 第二监测单元, 用于从第一辅载波或传输载波监测第一辅载波的
PDCCH下行调度信息, 所述 PDCCH下行调度信息包括 PDCCH格式 1, PDCCH格式 1A, PDCCH格式 1B, PDCCH格式 1C, PDCCH格式 1D, PDCCH格式 2, 或 PDCCH格式 2A;
第二传输单元, 用于根据所述 PDCCH调度信息利用所述第一辅载波 接收下行数据。
当第一辅载波只传输下行数据时, 第一辅载波中只有下行传输子帧, 移动终端可以从第一辅载波或传输载波的下行传输子帧接收基站发送的 PDCCH调度信息, 则移动终端只监测 PDCCH格式 1, PDCCH格式 1A, PDCCH格式 1B, PDCCH格式 1C, PDCCH格式 1D, PDCCH格式 2, 以 及 PDCCH格式 2A中任意一个或多个 PDCCH调度信息, 忽略 PDCCH格 式 0、 PDCCH格式 3以及 PDCCH格式 3A的 PDCCH调度信息, 减少盲检 测 PDCCH 调度信息的格式数量, 移动终端可以加快针对第一辅载波的 PDCCH信息的处理。
第三种可能的结构, 所述第一辅载波为既传输上行数据也传输下行数 据的辅载波时:
第三监测单元, 用于监测第一辅载波的 PDCCH 调度信息, 所述 PDCCH调度信息包括 PDCCH上行调度信息和 PDCCH下行调度信息; 第三传输单元, 用于根据所述 PDCCH调度信息利用所述第一辅载波 传输上行数据和下行数据。
移动终端监测第一辅载波或传输载波的下行传输子帧发送的针对第 一辅载波的 PDCCH格式 0、 PDCCH格式 3以及 PDCCH格式 3 A的 PDCCH 调度信息, 根据所述 PDCCH调度信息利用第一辅载波的上行传输子帧向 基站传输上行数据。
移动终端监测基站从第一辅载波或传输载波的下行传输子帧发送的
PDCCH格式 1, PDCCH格式 1A, PDCCH格式 IB, PDCCH格式 1C, PDCCH 格式 1D, PDCCH格式 2, 以及 PDCCH格式 2A的任意一种或多种 PDCCH 调度信息, 根据所述 PDCCH调度信息利用所述第一辅载波接收下行数据。
此时, 移动终端既可以通过第一辅载波的下行传输子帧接收基站发送 的下行数据信息, 也可以通过第一辅载波的上行传输子帧向基站传输上行 数据洗信息。
