为了更清楚地说明本发明实施例的技术方案, 下面将对本发明实施例中 所需要使用的附图作筒单地介绍, 显而易见地, 下面所描述的附图仅仅是本 发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的 前提下, 还可以根据这些附图获得其他的附图。
图 1是本发明一个实施例的通信方法的示意性流程图。

图 7是本发明另一个实施例的通信装置的示意性框图。 图 8是根据本发明实施例的物理层设备的框图。 具体实施方式
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的一部分实施例, 而不 是全部实施例。 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 造性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范围。
应理解, 本发明的技术方案可以应用于各种通信系统, 例如: 全球移动 通讯 ( Global System of Mobile communication, GSM )系统、码分多址 ( Code Division Multiple Access , CDMA ) 系统、 宽带码分多址(Wideband Code Division Multiple Access, WCDMA )系统、通用分组无线业务( General Packet Radio Service, GPRS )、 长期演进( Long Term Evolution, LTE ) 系统、 先进 的长期演进( Advanced long term evolution , LTE- A ) 系统、 通用移动通信系 统 ( Universal Mobile Telecommunication System, UMTS )等。
还应理解, 在本发明实施例中, 用户设备( UE, User Equipment ) 包括 但不限于移动台 ( MS, Mobile Station )、 移动终端( Mobile Terminal )、 移动 电话 ( Mobile Telephone )、 手机 ( handset )及便携设备 ( portable equipment ) 等, 该用户设备可以经无线接入网( RAN, Radio Access Network )与一个或 多个核心网进行通信, 例如, 用户设备可以是移动电话(或称为 "蜂窝" 电 话)、 具有无线通信功能的计算机等, 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置。
在各种制式的通信系统中, RAN 的信道的频带可以分为传输频带和保 护频带,其中 RAN的保护频带主要用于减少相邻信道的干扰。例如,在 LTE 系统中, 信道带宽可以为 20MHz, 其实际使用的传输频带的带宽为 18MHz, 在该传输频带的两侧分别设置了带宽为 1MHz的保护频带。
图 1是本发明一个实施例的通信方法的示意性流程图。 图 1的方法由发 送端执行, 例如, 当图 1描述下行业务时, 该发送端可以 站, 当图 1描 述上行业务时, 该发送端可以是 UE, 其中该 UE可以是专门用于窄带通信 的 UE, 如 M2M业务中的 UE。 该方法包括:
110、 生成第一信号;
120、 通过第一信道向接收端发送第一信号, 第一信道为用于窄带通信 的第一频带内的多个信道中的一个, 第一频带的至少部分位于 RAN的保护 频带内。
换句话说, 发送端可以至少部分使用 RAN的保护频带与接收端进行窄 带通信。 例如, 保护频带可以是位于 RAN的传输频带的一侧的高频的保护 频带, 也可以是 RAN的传输频带的另一侧的低频的保护频带, 或者是高频 的保护频带和低频的保护频带的组合。
在本发明实施例中, 通过利用 RAN的保护频带的频谱资源建立了适合 窄带通信的频谱资源, 并提高了频谱的利用率。
应理解, 本发明实施例对步骤 110中第一信号的具体形式不作限定, 可 以指控制信令, 也可以指业务数据, 其中业务数据可以根据实际的业务情况 确定, 例如, M2M 中的智能抄表业务, 该第一信号可以承载智能表所记录 的数据等。
应理解, 本发明实施例对步骤 120中的多个信道的具体类型不作限定, 当图 1描述下行业务时, 该多个信道为下行信道; 当图 1描述上行业务时, 该多个信道为上行信道。
步骤 120中的第一频带可以为一段连续的频带, 该频带用于窄带通信, 例如 M2M通信业务, 本发明的实施例并不限于此, 例如, 步骤 120中的第 一频带也可以为多段彼此不连续的频带。 另外, 第一频带的至少部分位于 RAN的保护频带内, 应理解, 只要第一频带与 RAN的保护频带存在重叠部 分的实施例均应落入本发明实施例的保护范围, 例如, 第一频带可以全部位 于 RAN的保护频带内; 或者, 第一频带的一部分位于 RAN的保护频带内, 另一部分占用 RAN的传输频带。
可选地, 作为一个实施例, 上述第一频带位于 RAN的保护频带内, 但 本发明实施例对第一频带在 RAN的保护频带内的分布不作具体限定,例如, 当保护频带为 0-lMHz, 第一频带可以是 0.1-0.7MHz。
可选地, 作为另一个实施例, 上述第一频带的中心频点与 RAN的保护 频带的中心频点相同。
举例说明, 在 LTE中, 假设信道带宽为 20MHz, 该信道的传输频带为 l-19MHz, Ο-lMHz是位于低频的保护频带, 19-20MHz是位于高频的保护频 带,该第一信道可以位于低频的保护频带内,也可以位于高频的保护频带内。 具体地, 当图 1的方法由 UE执行时, 上述第一信道可以为上行信道, 第一 频带可位于高频的保护频带内,如第一频带为 19-20MHZ,或者 19.l-19.9MHz 等; 当图 1的方法由基站执行时, 上述第一信道可以为下行信道, 第一频带 可位于低频的保护频带内, 如第一频带为 0-lMHz, 或者 0.1-0.9MHz。 应理 解,上述数值仅仅是举例说明,而非要将本发明实施例限定在具体的场景中, 实际中具体数值的选取可以根据窄带通信的业务种类以及所需的带宽等因 素选择。
进一步地, 第一频带与 RAN的传输频带之间设置有用于防止彼此信号 干扰的保护间隔。 例如, 当第一频带为 19.l-19.9MHz时, 19-19.1MHz之间 的频带即为该第一频带与 RAN 的传输频带之间的保护间隔, 同样地, 19.9-20MHz即为该第一频带与相邻 RAN的传输频带之间的保护间隔,在用 于窄带通信的第一频带与 RAN的传输频带之间设置保护间隔, 有利于降低 窄带通信与 RAN通信之间的信号干扰, 应注意, 本发明实施例对保护间隔 的具体数值不作限定,可以根据间隔大小与信号干扰之间的关系确定,例如, 如果窄带通信与 RAN通信之间的保护间隔设置为 140KHz,它们之间的信号 干扰已经可以忽略不计, 则可以将保护间隔设置为 140KHz。
可选地, 作为另一个实施例, 上述第一频带的一部分位于 RAN的保护 频带内, 该第一频带的另一部分占用 RAN的传输频带。 本发明实施例对第 一频带在 RAN保护频带内的部分与其在 RAN传输频带部分的比例不作具体 限定, 可以根据实际情况, 如窄带通信业务类型、 业务多少以及传输频带的 使用情况确定。
可选地, 作为另一个实施例, 上述第一频带的中心频点与 RAN的传输 频带的端点的频率相同, 且第一频带的一半位于 RAN的保护频带内, 另一 半占用 RAN传输频带的边缘频带。
具体地,仍采用上述 LTE中关于信道频带分布的 支设, 当图 1的方法由 UE执行时, 上述第一信道可以为上行信道, 第一频带可为 18.3-19.7MHz, 其中 19-19.7MHZ位于高频的保护频带内, 18.3-19MHZ位于传输频带内; 当 图 1 的方法由基站执行时, 上述第一信道可以为下行信道, 第一频带可为 0.3-1.7MHZ, 其中 0.3-lMHz位于低频的保护频带内, l-1.7MHz位于传输频 带内。
进一步地, 第一频带与 RAN的除去第一频带所占用的传输频带之外的 其余传输频带之间设置有用于防止彼此信号干扰的保护间隔。 换句话说, 传 输频带可以分为用于第一部分、第二部分和位于第一部分与第二部分之间保 护间隔, 其中第一部分分配给第一频带使用, 保护间隔用于防止第一频带与 传输频的第二部分之间的信号干扰。 例如, RAN的传输频带为 1-19MHZ, 当第一频带为 18.3-19.7MHz时, 18.3-19MHz为第一频带占用的传输频带, RAN 的除去所述第一频带所占用的传输频带之外的其余传输频带为 l-18.3MHz, 此时, 可以将 18.l-18.3MHz的频带设置为保护间隔, 在该保护 间隔内不传输任何信号, 从而减少窄带通信与 RAN的剩余传输频带通信之 间的信号干扰。
应理解, 本发明实施例对第一频带中的多个信道的个数不作具体限定, 具体地, 可以根据该第一频带用于上行传输还是下行传输、 该第一频带中承 载窄带通信业务的多少等因素确定。 另外, 可选地, 第一频带内的多个信道 间隔排布。 即相邻两个信道之间设置保护间隔, 有利于相邻减少相邻信道之 间的信号干扰。 例如, 当第一频带用于承载上行业务时, 可以设置 64个上 行信道, 且相邻窄上行带信道之间设置一定的保护间隔; 当第一频带用于承 载下行业务时, 可以设置 16个下行信道, 且相邻下行信道之间设置一定的 保护间隔。
上文中结合图 1 , 从发送端的角度详细描述了根据本发明实施例的通信 方法, 下面将结合图 2,从接收端的角度描述根据本发明实施例的通信方法。
应理解, 接收端侧描述的发送端与接收端的交互及相关特性、 功能等与 发送端侧的描述相应, 为了筒洁, 适当省略重复的描述。
图 2是本发明另一个实施例的通信方法的示意性流程图。 图 2的方法由 接收端执行, 例如, 当图 2描述上行业务时, 该接收端可以是基站, 当图 2 描述下行业务时, 该接收端可以是 UE, 其中该 UE可以是专门用于窄带通 信的 UE, 如 M2M通信中的 UE。
210、 通过第一信道接收发送端发送的第一信号, 第一信道为用于窄带 通信的第一频带内的多个信道中的一个, 第一频带的至少部分位于无线接入 网络 RAN的保护频带内;
220、 对第一信号进行处理。
在本发明实施例中, 通过利用 RAN的保护频带的频谱资源建立了适合 窄带通信的频谱资源, 并提高了频谱的利用率。
可选地, 作为一个实施例, 上述第一频带位于 RAN的保护频带内。 可选地, 作为另一个实施例, 第一频带的中心频点与 RAN的保护频带 的中心频点相同。
可选地, 作为另一个实施例, 第一频带与 RAN的传输频带之间设置有 用于防止彼此信号干扰的保护间隔。
可选地, 作为另一个实施例, 第一频带的一部分位于 RAN的保护频带 内, 第一频带的另一部分占用 RAN的传输频带。
可选地, 作为另一个实施例, 第一频带的中心频点与 RAN的传输频带 的端点的频率相同, 且第一频带的一半位于 RAN的保护频带内, 另一半占 用 RAN传输频带的边缘频带。
可选地, 作为另一个实施例, 第一频带与 RAN的除去第一频带所占用 的传输频带之外的其余传输频带之间设置有用于防止彼此信号干扰的保护 间隔。
可选地, 作为另一个实施例, 第一频带内的多个信道间隔排布。
下面结合具体例子, 更加详细地描述本发明实施例。 应注意, 图 3的例 子仅仅是为了帮助本领域技术人员理解本发明实施例, 而非要将本发明实施 例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图 3的 例子, 显然可以进行各种等价的修改或变化, 这样的修改或变化也落入本发 明实施例的范围内。
图 3是本发明实施例的 RAN频谱规划的示意图。 在图 3中, RAN的信 道带宽共 20MHz, 分为 3部分: RAN低频保护频带(0-lMHz )、 RAN传输 频带 (1-19MHZ ) 以及 RAN高频保护频带 ( 19-20MHz )。 其中, RAN低频 保护频带内与 RAN高频保护频带内均设置有一个图 1-图 2所描述的第一频 带, 分别承载 M2M下行业务和 M2M上行业务。
具体地, 在 RAN高频保护频带内, 以 19.5MHz为中心(参见图 3中的 M2M高频中心频点)设置 64个上行信道,每个上行信道带宽为 3.75KHz(参 见图 3 中的子信道有效带宽), 且每个上行信道两侧各设置带宽为 3.75KHZ 的保护间隔, 则一个上行信道实际占用 3.75 χ 3=11.25ΚΗζ的带宽(参见图 3 中的子信道带宽), 上行频带总带宽为 11.25KHz x 64=720KHz, RAN高频保 护频带两端各剩余 140KHz的保护间隔(参见图 3中的高频保护间隔 1和高 频保护间隔 2 )。
同样地, 在 RAN低频保护频带内, 以 0.5MHz为中心 (参见图 3中的 M2M低频中心频点)设置 16个下行信道, 每个下行信道带宽为 30KHz (参 见图 3中的子信道有效带宽), 且每个下行信道两侧合计设置带宽为 15KHz 的保护间隔, 则一个下行信道实际占用 45KHz的带宽 (参见图 3 中的子信 道带宽), 下行频带总带宽为 45 X 16=720KHz, 保护频带两端同样各剩余 140KHz的保护间隔 (参见图 3中的低频保护间隔 1和低频保护间隔 2 )。

图 8是根据本发明实施例的物理层设备的框图。 在图 8中, 发送端 810 的物理层设备包括: 信道编码模块 811、 星座图映射模块 812、 多速率滤波 模块 813、 上变频模块 814、数 /模变换模块 815和射频模块 816; 接收端 820 的物理层设备包括: 射频模块 821、 数 /模变换模块 822、 下变频模块 823、 多速率滤波模块 824、 星座图解映射模块 825和信道译码模块 826。
具体地, 发送端 810将原始数据比特经过信道编码模块 811和星座图映 射模块 812后, 得到待发送的数据符号; 然后, 经过多速率滤波模块 813提 高发送符号的采样率; 接下来, 通过数字上变频模块 814, 将窄带信号 (如 M2M信号 )调制到 RAN的保护频带内; 最后, 通过数 /模变换模块 815和 射频模块 816上变频, 将信号发送到信道中。 其中, 对于下行发送, 窄带通 信(如 M2M通信)可共享 RAN基站的 RRU和天线。
在接收端 820,信道传输的射频信号经过射频模块 821和模 /数变换模块 822,得到基带接收信号;接下来,通过下变频模块 823,将窄带信号从 RAN 的保护频带内搬移至零频附近; 然后, 通过多速率滤波模块 824降低接收信 号的采样速率, 并滤除带外噪声和干扰; 最后, 通过星座图解映射模块 825 和信道译码模块 826, 得到发送的比特数据。
发送端, 通过数字上变频, 将窄带(如 M2M )基带信号搬移到 RAN传 输频带之外的邻近频带; 接收端, 通过数字下变频, 将窄带信号从 RAN传 输频带之外的邻近频带搬移至零频附近, 以获得窄带基带信号。
在基站侧, 利用多速率滤波器调整窄带信号的采样速率, 使之与 RAN 基带信号匹配,从而可以共用 RAN的 RRU; 而在终端侧,窄带通信终端(如 M2M终端)只需处理窄带信号, 从而降低功耗和成本。
发送端, 利用多速率滤波器中的低通滤波器抑制窄带信号的带外扩散, 使得窄带信号对 RAN信号的干扰几乎可忽略。
