- the data rate provided by the mobile communication system for the cell center and the cell edge user is very different.
- the data rate enjoyed by the cell center user is much higher than the data rate enjoyed by the cell edge user. Therefore, the service experience of the cell edge user is much lower than that of the cell.
- the service experience of the central user For the actual operation of the network, if you want to obtain high user satisfaction, you must consider improving the quality of service to the cell edge users, that is, increasing the data rate provided to the cell edge users, and multi-carrier technology as the service quality of the cell edge users.
- TD-HSDPA Time Division-High Speed Downlink Packet Access
- HSDPA dual-carrier Dual Cell
- LTE-Advanced Long Term
- Carrier-aggregation of Evolution-Advanced is a multi-carrier technology.

- the antenna is the same.
- Figure 1 shows a schematic diagram of a configuration method using a dual-carrier overlapping coverage mode in the case of a simplified omnidirectional antenna. As shown in Figure 1, in this configuration mode, it belongs to the same base station (NodeB).
- the transmit antennas of different carriers are co-located, that is, all carriers are transmitted on each transmit antenna.
- the multi-carrier mobile communication system configured by this scheme can approximately double the data rate of the cell edge users and improve the service experience of the users at the edge of the area.
- the scheme improves the data rate of the cell edge user through multi-carrier aggregation, since the transmitting antennas of different carriers of the same base station are shared (or co-located), the cell is also simultaneously The data rate of the central user is multiplied, resulting in a difference between the two.
- the data rate of the cell edge user and the cell center user can be approximated by N times, and the data rate difference provided in the entire cell is compared with that of the single carrier ( Variance) is an increase of N 2 times.
- the multi-carrier overlap coverage increases the data rate of the cell edge users, it increases the difference of the services provided by the network in different geographical areas, and the service consistency of the mobile communication system in the geographical area is deteriorated.
- it is very important to provide services with consistent shields in different geographical areas. This is because when the user moves from the central area of the cell to the edge of the cell, the significant drop in the data rate obtained will result in The rapid increase in user dissatisfaction.
- relay technology is also being studied as a solution to the problem of low cell edge data rate.
- the Relay technology mainly arranges some relay stations at the edge of the cell, and when the user moves to the cell edge area, it connects with the relay station, and then the relay station transmits the data back to the base station.
- the relay stations arranged sometimes need to have more complicated functions, so the implementation process is more complicated. Summary of the invention

- a second transmit antenna configured to send a second carrier
- the geographic location of the second transmit antenna is a predetermined distance from the geographic location of the first transmit antenna.
- the geographic location of the second transmit antenna of the second carrier belonging to the same base station is obtained by shifting the geographic location of the first transmit antenna of the first carrier belonging to the base station by a preset distance, that is, different carriers belonging to the same base station. Transmitting antennas are in different geographical locations, and then transmitting the first carrier by using the first transmitting antenna, and transmitting the second carrier by using the second transmitting antenna, so that the data rate of the cell edge user of a certain carrier is increased, and This complementary superposition of data rates improves the consistency of service quality in different geographical areas.

Description
多载波移动通信系统中的通信方法、 基站以及通信系统 技术领域
本发明涉及无线技术领域， 尤其涉及一种多栽波移动通信系统中的通信 方法、 基站以及一种通信系统。 背景技术
移动通信系统为小区中心和小区边缘用户提供的数据速率存在很大差 别， 小区中心用户享有的数据速率比小区边缘用户享有的数据速率高得多， 因此， 小区边缘用户的服务体验远低于小区中心用户的服务体验。 而对于网 络实际运营， 如果希望获得较高的用户满意度， 就必须考虑提高对小区边缘 用户的服务质量， 即提高提供给小区边缘用户的数据速率， 而多载波技术作 为提高小区边缘用户服务质量的关键技术得到了应用， 例如多载波时分高速 下行分组接入 ( TD-HSDPA , Time Division-High Speed Downlink Packet Access )、 HSDPA的双载波（ Dual Cell )和更长期演进 ( LTE-Advanced, Long Term Evolution-Advanced )的载波聚合 ( Carrier Aggregation )都属于多载波技 术。
现在的多载波移动通信系统中载波与天线的配置是采用多载波重叠覆盖 的方式（例如， HSDPA中的 dual cell采用这种方式）， 即属于同一基站的不同 载波的发射天线共址（或发射天线相同）， 图 1示出了一种简化的全向天线情 况下采用双载波重叠覆盖方式的配置方法示意图， 由图 1 可以看出， 在这种 配置方式下， 属于同一基站（NodeB )的不同载波的发射天线共址， 即每个发 射天线上都发送所有载波。 与单载波移动通信系统相比， 采用此方案配置的 多载波移动通信系统可以近似成倍的提高小区边缘用户的数据速率， 改善小 区边缘用户的服务体验。
然而， 该方案虽然通过多载波聚合提高了小区边缘用户的数据速率， 但 是由于同一基站的不同载波的发射天线共用 （或者共址）， 所以同时也将小区
中心用户的数据速率成倍的提高了， 从而导致二者之间的差异是不降反增的。 例如， 与单载波相比， 当移动通信系统采用 N载波聚合重叠覆盖后， 小区边 缘用户和小区中心用户的数据速率都可近似认为提高了 N倍， 而整个小区内 提供的数据速率的差异（方差）却是增加了 N2倍。 可见， 多载波重叠覆盖虽 然提高了小区边缘用户的数据速率 , 但是却增大了网络在不同地理区域上提 供服务的差异， 导致移动通信系统在地理区域上的服务一致性变差。 而对于 网络实际运营来讲， 在不同地理区域上提供盾量一致的服务是非常重要的， 这是因为当用户从小区中心区域运动到小区边缘时， 其获得的数据速率的显 著下降将会导致用户不满意度的迅速增加。
此外， 目前在 LTE-Advanced中， 中继（ Relay )技术也正在被充分研究作 为解决小区边缘数据速率较低的问题。 Relay技术主要是在小区边缘处布置一 些中继站， 而当用户移动到小区边缘区域时则与中继站相连接， 然后再由中 继站将数据回传给基站。 但是所布置的中继站有时需要具有较复杂的功能， 因此实施过程较复杂。 发明内容
本发明实施例提供一种多载波移动通信系统中的通信方法， 用以在提高 'J、区边缘用户的数据速率的同时， 提高不同地理区域上服务质量的一致性， 并且实施过程较简单。
相应地， 本发明实施例还提供一种基站以及一种通信系统。
本发明实施例提供一种多载波移动通信系统中的通信方法， 包括： 确定属于基站的第一载波的第一发射天线的地理位置；
将确定出的第一发射天线的地理位置平移预设距离， 得到属于所述基站 的第二载波的第二发射天线的地理位置；
采用所述第一发射天线发送第一载波， 以及采用所述第二发射天线发送 第二载波。
本发明实施例提供一种基站， 包括：
第一发射天线， 用于发送第一载波；
第二发射天线， 用于发送第二载波；
其中， 所述第二发射天线的地理位置与所述第一发射天线的地理位置相 距预设距离。
本发明实施例提供一种通信系统， 包括多个基站， 其中每个基站包括： 第一发射天线， 用于发送第一载波；
第二发射天线， 用于发送第二载波；
所述第二发射天线的地理位置与所述第一发射天线的地理位置相距预设 距离。
本发明实施例通过将属于基站的第一载波的第一发射天线的地理位置平 移预设距离， 得到属于同一基站的第二载波的第二发射天线的地理位置， 即 属于同一基站的不同载波的发射天线处于不同的地理位置， 再釆用所述第一 发射天线发送第一载波， 以及采用所述第二发射天线发送第二载波， 使得某 一载波的小区边缘用户的数据速率提高， 并由于这种数据速率的互补式叠加， 提高了不同地理区域上服务质量的一致性， 另外， 由于布置天线要比布置中 继站简单得多， 因此， 实施过程较简单。 附图说明

针对现有技术中存在的问题， 为了在提高小区边缘用户的数据速率的同 时， 提高不同地理区域上服务质量的一致性， 并使得实施过程比较简单， 本 发明实施例提供了一种多载波移动通信系统中的通信方法 , 将载波与发射天 线绑定， 即每一个发射天线只属于一个载波， 一个载波可以对应多个发射天 线， 并且在确定出属于基站的一个载波的发射天线的地理位置的基础上， 平 移预设距离后， 得到属于同一基站的另一个载波的发射天线的地理位置， 从 而实现多载波部分重叠覆盖， 以及采用地理位置不同的发射天线发送不同载 波。
下面结合说明书附图对本发明的具体实施方式进行详细描述。
如图 2所示， 为本发明实施例提供的多载波移动通信系统中通信方法的 原理流程图， 具体步骤如下：
步骤 210、 确定属于基站的第一载波的第一发射天线的地理位置； 步骤 220、将确定出的第一发射天线的地理位置平移预设距离，得到属于 该基站的第二载波的第二发射天线的地理位置；
步骤 230、采用所述第一发射天线发送第一载波， 以及采用所述第二发射 天线发送第二载波。
其中， 第一发射天线与基站的第一载波绑定， 第二发射天线与基站的第 二载波绑定， 则该基站的不同载波对应的发射天线的地理位置不同。 基于这 种地理位置不同的发射天线进行不同载波的发送， 即可在提高小区边缘用户 的数据速率的同时， 提高不同地理区域上服务质量的一致性， 而且实施过程 比较简单。
对于网络中的所有基站， 都可以采用上述步骤 210和步骤 220的方法进
行载波与天线的配置， 较佳地， 将确定出的每个基站的笫一载波的第一发射 天线的地理位置沿相同方向平移预设距离， 就可以得到各个基站的第二栽波 的第二发射天线的地理位置， 从而实现整个第一载波的小区拓朴的整体平移， 避免为第二载波重新进行各个小区覆盖范围的确定。
较佳地， 所述预设距离为基站的第一栽波的小区中心到小区边界的距离。 这样， 第一载波的小区中心， 同时又是第二载波的小区边界； 第一载波的小 区边界， 同时又是第二载波的小区中心， 因此， 实现了小区边界和小区中心 的数据速率的互补式叠加， 不仅提高了小区边缘用户的数据速率， 还提高了 不同地理区域上服务质量的一致性。
当然， 所述预设距离也可以是任何大于零且小于小区中心到小区边界距 离的值， 只要保证属于同一基站的第二载波对应的发射天线与第一载波对应 的发射天线位于不同的地理位置即可， 只要满足这一条件， 就能够实现网络 中同一地理区域上的数据速率的互补式叠加， 并能够提高不同地理区域上服 务质量的一致性。
图 3 示出了采用上述本发明实施例提供的多载波移动通信系统中载波与 天线配置方法的示意图， 图中假设该多载波移动通信系统采用全向天线两载 波的工作方式。 其中， 在系统覆盖范围内的某一地理区域属于某个载波的小 区中心， 同时又属于另一个载波的小区边界。
下面以在 LTE- Advanced系统中采用上述通信方法为例，对本发明实施例 的具体实施过程进行详细描述， 具体步骤如下：
步骤 1、 选取系统的多载波中的某一载波（第一载波）， 对属于各个基站 的该载波对应的所有发射天线的地理位置进行确定， 这里， 可以根据现有的 单载波系统组网方法进行发射天线地理位置的确定， 例如参照 LTE-R8 或 LTE-R9组网方法进行组网， 确定出的该载波对应的所有发射天线的地理位置 如图 4所示。 其中， 各个小区基站的发射天线分别用 al-a7表示（这里假设组 成的网络由 7个小区构成）。
步骤 2、 选取系统的多载波中的另一载波（第二载波）， 将上一步骤中确
定出的第一载波的发射天线的地理位置沿相同方向平移预设距离， 较佳地， 该预设距离为基站的第一栽波的小区中心到小区边界的距离， 从而得到各个 基站的第二载波对应的所有发射天线的地理位置， 如图 5A所示， 图中， 发射 天线用一个字母加一个数字的方式表示， 不同的字母表示不同的载波， 不同 的数字表示不同的基站， 即字母相同数字不同的发射天线属于不同基站的相 同载波， 而字母不同数字相同的发射天线属于相同基站的不同载波。
当预设距离为大于零小于小区中心到小区边界距离的值时， 得到的各个 基站的第二载波对应的所有发射天线的地理位置如图 5B所示。 由图 5B可以 看出， 只要将第一载波的发射天线的地理位置沿相同方向平移一定的距离， 即可实现多载波的部分重叠覆盖， 就能够在提高小区边缘用户的数据速率的 同时， 提高不同地理区域上服务盾量的一致性。
步骤 3、 重复执行步骤 2， 直到系统的所有载波与发射天线都配置完成； 步骤 4、 采用地理位置不同的发射天线发射不同的载波。
上述只是以 LTE-Advanced系统为例，说明本发明实施例的具体实施方式， 但本发明实施例提供的多载波移动通信系统中的通信方法不仅仅适用于 LTE-Advanced系统， 而是适用于所有多载波移动通信系统。
其中， 属于同一基站的不同载波意味着只是不同载波对应的发射天线的 地理位置不同， 而基带处理以及高层的资源管理等都在同一基站内完成。 采 用上述载波与天线的配置方法的多载波移动通信系统与采用载波重叠菝盖配 置方式的多载波移动通信系统相比， 并没有增加基站的数量， 而只是将载波 与发射天线进行了绑定， 并且对发射天线按不同的地理位置分开摆放， 再基 于确定了地理位置的发射天线进行数据通信， 因此， 不仅提高了多载波移动 通信系统的峰值速率， 以及提高了小区边缘用户的数据速率， 还提高了网络 在不同地理区域上提供服务盾量的一致性。
相应地， 本发明实施例还提供一种基站， 其结构如图 6所示， 包括： 第一发射天线 610， 用于发送第一载波；
第二发射天线 620， 用于发送第二载波；
其中， 所述第二发射天线 620的地理位置与所述第一发射天线 610的地 理位置相距预设距离。
较佳地， 所述预设距离为第一载波的小区中心到小区边界的距离。
相应地， 本发明实施例还提供了一种通信系统， 如图 7所示， 包括多个 基站， 其中的每个基站包括：
第一发射天线， 用于发送第一载波；
第二发射天线， 用于发送第二栽波；
所述第二发射天线的地理位置与所述笫一发射天线的地理位置相距预设 距离， 即将所述第一发射天线的地理位置平移预设距离， 就能得到所述第二 发射天线的地理位置。
较佳地， 所述预设距离为所述第一载波的小区中心到小区边界的距离。 当然， 所述预设距离也可以为任何大于零且小于所述第一载波的小区中心到 小区边界距离的值。
基于上述通信系统进行数据通信， 即可在提高小区边缘用户数据速率的 同时， 提高不同地理区域上服务质量的一致性。
采用本发明实施例提供的多载波移动通信系统中的通信方法， 在进行多 载波小区覆盖范围规划时， 与单载波相比， 并没有增加基站的数量， 而是将 属于同一基站的不同载波的发射天线分开布置， 从而达到不同载波的小区部 分重叠， 基于这样布置的发射天线进行载波发送， 能够均衡每个基站覆盖范 围内不同地理区域上可提供的数据速率， 从而在提高小区边缘用户的数据速 率的同时， 提高不同地理区域上服务质量的一致性， 而且布置天线的实施过 程比较筒单易行。
显然， 本领域的技术人员可以对本发明进行各种改动和变型而不脱离本 发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
