本发明有益效果如下:
在本发明实施例提供的技术方案中, 由于能够将非对称的频谱资源如保护带宽中的频 谱资源使用载波聚合技术聚合后使用, 因此, 使得终端可以在非对称的频谱资源如保护带 宽内的该小区上工作, 提高了频语使用效率, 降低了系统成本。 附图说明
图 1为背景技术中 TDD和 FDD频谱使用方案示意图;
图 2为本发明实施例中利用了保护带宽的 TDD和 FDD频谱使用方案示意图; 图 3为本发明实施例中 LTE小区的载波分布示意图;

图 8为本发明实施例中用户设备结构示意图。 具体实施方式
发明人在发明过程中注意到: 在现有的频谱资源中, 有一些非对称的频谱资源, 它们能用于上行数据传输, 但是, 它们并不存在对应的频谱资源用于下行数据传输, 或者, 这些频谱资源能用于下行数据传 输, 但是, 它们并不存在对应的频谱资源用于上行数据传输, 下面以虚拟 TDD 小区为例 来说明这一类频谱资源。
图 2为预留了保护带宽的 TDD和 FDD频语使用方案示意图,一种利用两个保护带宽
G1和 G2的方案可以将上行 U3和下行 D4的频谱资源利用起来, 由于与 G1相邻的 FDD 频带被用作上行传输, 因此, 为了避免千扰, 只利用上行 U3 的频谱资源传输上行数据。 同样的道理, 下行 D4的频谱资源只传输下行数据。 为了使上行 U3和下行 D4可以工作起 来, 一种可行方案是将下行 D3和上行 U3组成一个虚拟的 TDD小区 (只有上行 U3对应 了实际的物理资源,下行 D3是虚拟的逻辑概念 ),上行 U4和下行 D4组成一个虚拟的 TDD 小区 (只有下行 D4对应了实际的物理资源, 上行 U4是虚拟的逻辑概念)。 这两种小区都 可以称为虚拟的 TDD小区。
在现有系统中, UE只能工作在 FDD小区或者对称的 TDD小区 (即上下行都工作在 同一频率上的 TDD小区)上。 然而, 对于 LTE-A ( Long Term Evolution- Advanced, 长期 演进升级) 系统而言, 为了提高 TDD频语使用效率, UE可能在非对称的 TDD小区上工 作, 例如, TDD小区只有一个传输方向是有实际频谱资源的, 另一个方向是虚拟的。也即, 该频谱资源能用于上行数据传输但无对应的频谱资源用于下行数据传输, 或该频谱资源能 用于上行数据传输但无对应的频谱资源用于下行数据传输, 这里的对应可以是 TDD 方式 对应, 用于上行数据传输的频谱资源与用于下行数据传输的频谱资源为同频资源且工作在 不同时隙。
下面对载波聚合技术进行说明。
图 3为 LTE ( Long Term Evolution, 长期演进) 系统中小区的载波分布示意图, 如图 所示, 在 LTE及以前的无线通信系统中, 一个小区中只有一个载波, 在 LTE系统中终端 可以使用的最大带宽为 20MHz。
在 LTE-A系统中, 系统的峰值速率比 LTE有巨大的提高, 要求达到下行 lGbps, 上行
500Mbps。 如果只使用一个最大带宽为 20MHz的载波是无法达到峰值速率要求的。 因此, LTE-A系统需要扩展终端可以使用的带宽, 由此引入了 CA ( Carrier Aggregation, 载波聚 合)技术, 即将同一个 e B (演进基站)下的多个连续或不连续的载波聚合在一起, 同时 为 UE ( User Equipment, 用户设备)服务, 以提供数据传输所需的速率。 这些聚合在一起 的载波又称为成员载波( component carrier, 筒称 CC )。 每个小区使用的载波都可以是一个 成员载波, 不同 eNB下的小区使用的载波(成员载波)不能聚合。 图 4为釆用 CA的 LTE 小区的载波分布示意图, 如图所示, 为了保证 UE能在每一个聚合的载波下工作, 每一个 载波的最大带宽不超过 20MHz。
目前, 在 LTE-A系统的载波聚合技术中, UE只能聚合 FDD小区或者对称的 TDD小 区。 为了提高 TDD频语使用效率, 发明人发现一些原本作为保护带宽的部分非对称的资 源可以作为虚拟 TDD小区加以利用。 出于避免来自相邻 FDD小区千扰的考虑, 当这样的 保护带宽被用作 TDD 方式工作时, 会出现上下行分别工作在不同频率上的情况。 因此, 有必要给出上述场景下 TDD的工作方式。
然而, 目前还没有针对 UE如何在虚拟的 TDD小区上工作的解决方案,特别是只有上 行存在实际物理资源, 而下行是虚拟的逻辑概念的 TDD小区。
鉴于此, 本发明实施例提出了一种在只有上行存在实际物理资源, 而下行是虚拟的逻 辑概念 TDD小区,或者,只有在下行存在实际物理资源,而上行是虚拟的逻辑概念的 TDD 小区上工作的方案, 下面结合附图对本发明的具体实施方式进行说明。
在说明过程中, 将先分别从 UE侧与基站侧的实施进行说明, 然后以实例对二者的配 合实施进行说明, 但这并不意味着二者必须配合实施, 实际上, 当 UE与基站分开实施时, 也分别解决了在 UE侧、 基站侧上存在的问题, 只是二者结合使用时, 会获得更好的技术 效果。
图 5为基站侧对频谱资源进行处理的方法实施流程示意图, 可以包括如下步骤: 步骤 501、 基站确定需要处理的频谱资源, 所述频谱资源能用于上行数据传输, 且无 与所述频谱资源有上下行对应关系的下行频谱资源用于下行数据传输, 或者, 所述频谱资 源能用于下行数据传输, 且无与所述频谱资源有上下行对应关系的上行频谱资源用作上行 数据传输; 这里的上下行对应关系可以是, 用于上行数据传输的频谱资源与用于下行数据 传输的频谱资源为同频资源且工作在不同时隙。
步骤 502、 基站确定需要对所述频谱资源利用后, 通知 UE使用载波聚合技术聚合所 述频谱资源。 具体地, 是通知 UE将所述频谱资源添加到载波聚合集合内, 使用载波聚合 技术聚合所述载波聚合集合内的频谱资源,则所述频谱资源参与载波集合,得到有效利用。
如果所述频谱资源能用于上行数据传输, 且无与所述频谱资源有上下行对应关系的下 行频谱资源用于下行数据传输, 则基站确定需要将所述频谱资源用于上行数据传输时, 确 定需要对所述频谱资源利用; 如果所述频谱资源能用于下行数据传输, 且无与所述频谱资 源有上下行对应关系的下行频谱资源用于上行数据传输, 则基站确定需要将所述频谱资源 用于下行数据传输时, 确定需要对所述频谱资源利用。

基站可以在 RRC信令中包含该频谱资源所属的虚拟小区的公共配置参数, 如 TDD配 置 (包括子帧配置和特殊子帧配置)、 MBSFN子帧配置等。
上述方案中, 除了特别提到 TDD 小区的地方, 其他的也适用于单向的、 只有上行的 虚拟 FDD小区、 只有上行的辅小区 (包括 TDD和 FDD )、 扩展载波、 载波 segment以及 单独的上行 FDD载波。
下面以实例进行说明。
实施例 1
本实施例将介绍聚合上行 TDD虚拟小区的实施。 网络场景如图 2所示为:
存在两个相邻的 TDD小区, 小区 1和小区 2, 小区 1所用频谱资源与 FDD小区的上 行频谱资源相邻, 二者之间有保护带宽 G1 , 小区 2所用频谱资源与 FDD小区的下行频谱 资源相邻, 二者之间有保护带宽 G2。 为了提高频谱利用率, 在 G1 引入一个只有上行 U3 的虚拟 TDD小区, 在 G2引入一个只有下行 D4的虚拟 TDD小区。
UE当前在小区 1和小区 2上工作, 其中小区 1为主小区, 由于上行业务量的增加, 网络判决为 UE增加聚合载波, 即为 UE聚合 U3。 此时, 网络将 U3和 D3组成一个虚拟 的 TDD小区, 然后将该虚拟 TDD小区的上行、 下行、 跨载波调度以及公共配置信息, 通 过 RRC专用信令通知 UE, 由于是初始添加该虚拟 TDD小区, RRC信令中的相关参数可 以使用完全配置的方式。 其中, 上行配置参数包括虚拟 TDD小区的上行载波的中心频点、 带宽、最大允许的上行发射功率、上行 CP长度、功控相关参数、天线相关参数、 PUSCH/SRS 传输相关的参数等;下行配置参数包括虚拟 TDD小区的小区索引、小区标识(频点和 PCI ) 等; 跨载波调度参数包括调度该虚拟 TDD 小区的其他小区的小区索引; 公共配置参数包 括该虚拟 TDD小区的 TDD配置 (包括子帧配置和特殊子帧配置)、 MBSFN子帧配置等。
UE收到该 RRC信令,添加该虚拟 TDD小区( U3 )到载波聚合集合内,然后使用 RRC 信令中的参数进行配置。 之后基站通过 MAC CE激活 UE在该小区上工作。 基站将该虚拟 TDD小区的路损参考及定时参考均配置到小区 1上, UE根据小区 1的参考信息在该虚拟 TDD小区上工作。 基站将该虚拟 TDD小区配置为跨载波调度, 调度它的小区是小区 1 , UE在工作时监听小区 1的 PDCCH, 接受对 U3调度的上行调度信令, 在 U3上进行上行 数据传输。 另外, 基站通过配置 SRS及调度 PUSCH数据, 得到 U3的上行信道盾量信息, 对该小区(U3 )进行载波管理。 如果 U3的 SRS信道盾量较差, 基站则可以通过 MAC CE 去激活该虚拟小区, 或者通过 RRC信令释放该虚拟小区。 UE在该虚拟 TDD小区 ( U3 ) 上进行工作时, 在该小区的下行子帧位置, 不检测本小区的 PDCCH、 不接受下行调度(不 接收本小区的 PDSCH ), 如果收到下行调度信令, 则 UE主动忽略, UE不进行测量 (包括 RSRP、 RSRQ等), 不进行无线链路监测。
实施例 2
本实施例将介绍聚合下行 TDD虚拟小区的实施。 网络场景同实施例 1为:
UE当前在小区 1和小区 2上工作, 由于下行业务量的增加, 网络判决为 UE增加聚合 载波, 即为 UE聚合 D4。 此时, 网络将 D4和 U4组成一个虚拟的 TDD小区, 然后将该小 区的下行、 跨载波调度以及公共配置信息, 通过 RRC专用信令通知 UE。 其中, 下行配置 参数包括虚拟 TDD小区的小区索引、 小区标识(频点和 PCI )等; 跨载波调度参数包括调 度该虚拟 TDD小区的其他小区的小区索引; 公共配置参数包括虚拟 TDD小区的 TDD配 置 (包括子帧配置和特殊子帧配置)、 MBSFN子帧配置等。
UE收到该 RRC信令,添加该虚拟 TDD小区( D4 )到载波聚合集合内,然后使用 RRC 信令中的参数进行配置。 之后基站通过 MAC CE激活 UE在该虚拟 TDD小区上工作。 基 站将该虚拟 TDD小区的路损参考及定时参考均配置在该小区自身上。 基站通过配置 RRM
( Radio Resource Management, 无线资源管理)测量及 CQI ( Channel Quality Indicator, 信 道盾量指示)上报, 得到 D4的下行信道盾量信息, 对该小区 (D4 )进行载波管理。 如果 D4的测量结果显示其下行信道盾量较差, 基站则可以通过 MAC CE去激活该虚拟小区, 或者通过 RRC信令释放该虚拟小区。 UE不接受对该小区的上行调度, 如果收到上行调度 信令, 则 UE主动忽略, 在该小区的上行子帧位置不进行 PUSCH、 CQI反馈及 SRS等上 行信号的传输。
