Description

数据传输方法、 基站及终端 技术领域
本发明涉及通信技术领域, 特别涉及一种数据传输方法、 基站及终端。 背景技术
在通信系统中, 为了降低终端的实现复杂度, 一般仅定义几种标准带宽, 终端仅需要设计不同标准带宽的滤波器来支持标准带宽。 例如 3GPP ( Thi rd Genera t ion Par tnershio Projec t , 第三代合作项目 ) LTE ( Long Term Evolut ion, 长期演进)仅定义了 6种标准带宽: 1. 4MHz、 3MHz、 5MHz、 10MHz、 15MHz和 20MHz , 但运营商所拥有的可用频谱并不一定局限于这些标准带宽。 现有技术提出了两种利用非标带宽的方案:
方案 1 : 将非标带宽分割为标准带宽的组合, 例如 8MHz的非标带宽可以分 割为 3MHz的标准带宽和 5MHz的标准带宽两个载波, 釆用载波聚合的方式将标 准带宽组合为非标带宽。
方案 2 : 增加所支持的标准带宽, 例如在现有的 6种标准带宽之外, 再增 加其他的标准带宽, 例如 7MHz、 8MHz、 9MHz等多个带宽。
在实现本发明的过程中, 发明人发现现有技术中至少存在如下问题: 釆用方案 1时, 并不一定所有的非标带宽都能够分割为标准带宽的组合, 例如 9MHz的非标带宽,即使是釆用 3MHz和 5MHz的标准带宽汇聚后,还是有 1MHz 的带宽浪费; 而釆用方案 2时, 由于引入了更多的标准带宽, 使得终端的滤波 器设计更为复杂, 增加了终端的实现复杂度。 发明内容
本发明的实施例提供一种数据传输方法、 基站及终端, 能够在不增加终 端实现复杂度的同时充分利用可用带宽。
本发明的实施例釆用的技术方案为:

接收基站通知的终端特定标准带宽的配置信息, 所述终端特定标准带宽 为基站传输带宽内的一段标准带宽, 且所述基站传输带宽为非标带宽;
釆用所述终端特定标准带宽, 与基站进行数据传输。

为使本发明技术方案的优点更加清楚, 下面结合附图和实施例对本发明 作详细说明。
实施例一
本发明实施例提供一种数据传输方法, 如图 1所示, 在基站侧, 所述方法 包括: 101、 当基站传输带宽为非标带宽时, 将所述基站传输带宽内的一段标准 带宽配置为终端特定标准带宽;
102、 将所述终端特定标准带宽的配置信息通知终端;
103、 在所述终端特定标准带宽内, 与终端进行数据传输。
本发明实施例提供的数据传输方法, 基站根据基站传输带宽, 为不同的 终端设置不同的终端特定标准带宽, 并将终端特定标准带宽的配置信息通知 终端, 在终端特定标准带宽内, 与终端进行数据传输。 与现有技术相比, 基 站能够将发送给终端的数据控制在基站传输带宽内的不同标准带宽内, 从而 充分利用基站传输带宽; 同时, 相对一个终端而言, 终端始终釆用标准带宽 接收信号, 从而不会增加终端实现的复杂度。 由于终端特定标准带宽是基站 为终端配置的, 每个终端被配置的终端特定标准带宽在基站传输带宽中位置 可以不固定。 可选地, 在本实施例的带宽配置方式中, 存在至少 2个终端的终 端特定标准带宽覆盖了彼此范围之外的部分频段, 使得多个终端能尽量占用 更多的基站传输带宽, 提高基站传输带宽的利用率。
实施例二
本发明实施例提供一种数据传输方法, 如图 2所示, 在终端侧, 所述方法 包括:
201、 接收基站通知的终端特定标准带宽的配置信息, 所述终端特定标准 带宽为基站传输带宽内的一段标准带宽, 且所述基站传输带宽为非标带宽;
202、 釆用所述终端特定标准带宽, 与基站进行数据传输。
本发明实施例提供的数据传输方法, 终端接收基站发送的终端特定标准 带宽的配置信息, 釆用所述终端特定标准带宽, 与基站进行数据传输。 与现 有技术相比, 基站能够将发送给终端的数据控制在基站传输带宽内的不同标 准带宽内, 从而充分利用基站传输带宽; 同时, 相对一个终端而言, 终端始 终釆用标准带宽接收信号, 从而不会增加终端实现的复杂度。
实施例三 如图 3所示, 所述数据传输方法包括:
301、 基站传输带宽为非标带宽, 基站将该基站传输带宽分为基站标准带 宽 (也称基站标准载波)和部分载波。
在 3GPP LTE REL-8中定义了 6种标准带宽: 1. 4ΜΗζ、 3ΜΗζ、 5ΜΗζ、 10ΜΗζ、 15ΜΗζ和 20ΜΗζ , 扣除保护带, 每种标准带宽分别对应于 6RB ( Resour se Block , 资源块)、 15RB、 25RB、 5 ORB , 75RB、 100RB的可用传输带宽,每个 RB为 180KHZ。 在本实施例中, 所述带宽为可以用来传输的带宽, 不包括保护带。
基站标准带宽可以设置为小于该基站传输带宽的任意标准带宽, 可选地, 基站标准带宽设置为最接近且小于该基站传输带宽的标准带宽。 例如: 当基 站传输带宽为 60RB时, 基站标准带宽可以设置为 6RB、 15RB、 25RB或 50RB, 可 选地, 基站标准带宽设置为 50RB。
可选地, 如图 4a所示, 可以将基站传输带宽的中心频段两侧的带宽设置 为基站标准带宽, 其余频段设置为部分载波(Segment Carr ier )。
可选地, 如图 4b所示, 可以将基站传输带宽分为两部分, 一部分为基站 标准带宽, 另一部分为部分载波。
在本发明所有实施例中, 所述的带宽是指一段频段, 包括该频段的大小 和其在频谱中的位置, 或者指所述频段的大小。 本领域的技术人员可以根据 上下文得知所述的带宽是指频段还是指频段的大小。
302、 在所述基站传输带宽内, 基站为终端配置终端特定标准带宽。
其中, 所述终端特定标准带宽可以配置为基站传输带宽内、 小于该基站 传输带宽的任意标准带宽。 如图 5所示, 每个终端的终端特定标准带宽的位置 可以不同。 终端的终端特定标准带宽也可以包括部分载波。 在本实施例中, 当为多个终端分别配置终端特定标准带宽时, 在所配置的多个终端特定标准 带宽中, 可至少存在 2个终端特定标准带宽覆盖了彼此范围之外的部分频段。 例如在图 5中, 由于基站为 2个终端配置的终端特定标准带宽分别覆盖了彼此 范围之外的部分频段, 相对于 2个终端使用同样的频段, 基站传输带宽中被不 同终端所利用的频段有所增加, 提高了带宽利用率。 可以理解, 多个终端的 终端特定标准带宽如果尽可能多的覆盖整个基站传输带宽, 那么基站传输带 宽将得到有效利用。
每个终端的终端特定标准带宽的大小可以配置为与基站标准带宽的大小 相同, 也可以不同。 可选地, 终端特定标准带宽的大小配置为与基站标准带 宽的大小相同。 例如: 基站传输带宽为 60RB, 基站标准带宽为 50RB, 可选地, 终端特定标准带宽配置为 50RB。
可选地, 终端特定标准带宽预先约定等于基站标准带宽。
303、 基站将该终端特定标准带宽的配置信息, 以及该基站标准带宽的设 置信息通知终端。
其中, 所述终端特定标准带宽的配置信息可以包括终端特定标准带宽的 大小和位置信息, 例如终端特定标准带宽的大小和起始位置。 如果预先约定 终端特定标准带宽的大小等于基站标准带宽的大小, 则所述终端特定标准带 宽的配置信息可以仅包括该终端特定标准带宽的位置信息。 例如: 所述终端 特定标准带宽的配置信息仅包括该终端特定标准带宽的起始位置信息。
进一步地, 基站可以在基站传输带宽内, 仅设定几种终端特定标准带宽 的位置, 以降低资源调度的复杂度。 例如: 基站传输带宽为 70RB, 基站标准 带宽为第 10RB-59RB的 50RB , 则基站可以设定终端特定标准带宽的大小为 5 ORB, 基站标准带宽内包括两种终端特定标准带宽: 一种终端特定标准带宽 的位置为第 0RB-49RB, —种终端特定标准带宽的位置为第 20RB-69RB; 基站设 定一部分终端的终端特定标准带宽的位置为第 0RB-49RB, 设定另一部分终端 的终端特定标准带宽的位置为第 20RB-69RB。 相应的, 基站可以仅将所述两种 终端特定标准带宽的大小和位置通知终端, 并分别通知各终端为其分配的是 两种终端特定标准带宽中的哪一种。
进一步地, 所述终端特定标准带宽的配置信息可以包括该终端特定标准 带宽的生效时间。 其中, 预先约定的生效时间为终端接收到基站配置的终端 特定标准带宽的时刻。
基站可以通过高层信令如 RRC ( Radio Resource Control , 无线资源控制) 信令, 或者, 通过 MAC ( Media Acces s Control , 媒体访问控制)层信令或物 理层信令将终端特定标准带宽的配置信息通知终端。 基站通过高层信令如 RRC 信令将终端特定标准带宽的配置信息通知终端是常见的实现方式; 终端特定 标准带宽的配置信息可以在 RRC连接建立、 RRC连接重配置、 RRC连接重新建立 以及其它涉及无线资源配置或者重配置的时刻予以更新。
所述基站标准带宽的设置信息的通知方式可以参照所述终端特定标准带 宽的通知方式, 例如在 3GPP LTE REL8及其后版本中, 可以在 MIB ( Mas ter Informa t ion Block, 主信息块) 消息携带基站标准带宽的大小, 终端通过解 MIB消息获得基站标准带宽。
304、 基站在所述终端特定标准带宽内, 与终端进行数据传输。
进一步的, 在所述基站标准带宽内, 与终端进行非终端特定数据的传输, 例如发送广播消息。
具体地, 当终端在初始接入基站的时候, 基站釆用所述基站标准带宽与 终端进行数据传输; 当终端在接收到基站发送来的终端特定标准带宽的配置 信息后, 基站釆用所述终端特定标准带宽与终端进行数据传输。
进一步地, 在基站所发送的数据中, 有发送给一组或者所有终端的数据, 如系统消息和寻呼消息以及公共控制信道、 同步信道等, 统称为广播消息, 也有仅发送给特定终端的特定数据。 基站在所述基站标准带宽内向一组或者 所有终端发送广播消息, 在终端特定标准带宽内向特定终端发送特定数据。
例如: 物理同步信道(包括主同步信号和辅同步信号)、 物理下行控制信 道(PDCCH )、 物理广播信道(PBCH )、 物理控制格式指示信道(PCFICH )、 物 理混合反馈重传指示信道(PHICH ), 以及在 LTE用户设备的公共搜索空间传输 的 PDCCH所指示的下行共享信道(PDSCH )和上行共享信道( PUSCH )在基站标 准带宽内发送和接收; 在 LTE用户设备的特定搜索空间传输的 PDCCH所指示的 PDSCH和 /或 PUSCH在终端特定标准带宽内发送和 /或接收。
进一步地, 由于终端在同一子帧可能既要接收来自基站的广播消息, 又 要接收终端特定数据, 因此, 可在所述基站标准带宽与多个终端特定标准带 宽所共有的带宽范围内, 向所述多个终端发送广播消息, 也就是说基站在所 述基站标准带宽与多个终端特定标准带宽中重合的那部分带宽上发送广播消 息。 基站在调度广播消息的传输资源时, 尽量调度到所有在该子帧同时接收 终端特定数据和广播消息的终端的终端特定标准带宽之内。如图 6所示,例如: 基站传输带宽为 70RB , 基站标准带宽为第 10RB-59RB的 50RB, 终端特定标准带 宽为 50RB , 终端 1的终端特定标准带宽的位置为第 0RB-49RB , 终端 2的终端特 定标准带宽的位置为第 20RB-69RB, 并且基站只有两个终端需要在同一子帧接 收广播消息, 则基站在调度广播消息时, 优先调度到第 20RB-49RB。
305、 终端釆用所述终端特定标准带宽, 与基站进行数据传输。
进一步的, 终端釆用所述基站标准带宽, 接收基站发送的广播消息。 当基站在基站标准带宽内向一组或者所有终端发送广播消息时, 对应地, 终端釆用所述基站标准带宽接收所述广播消息; 当基站在终端特定标准带宽 内向特定终端发送特定数据时, 对应地, 终端釆用所述终端特定标准带宽接 收所述特定数据。
进一步地, 如图 7所示, 当终端接收基站在所述基站标准带宽内发送的广 播消息时, 终端将接收中心频率调整到该基站标准带宽的中心频率, 将接收 滤波器带宽调整为基站标准带宽; 当终端接收基站在所述终端标准带宽内发 送的特定数据时, 终端将接收中心频率调整到该终端标准带宽的中心频率, 将接收滤波器带宽调整为终端特定标准带宽。
如图 8所示, 在 3GPP LTE中, 一个子帧大小为 lms , 分为两个时隙, 每个 时隙为 0. 5ms , 每个时隙包括 6-7个符号。 其中, 第一个时隙的前几个符号用 来传输 L1 /L2层的控制信令, 如 PBCH、 PCFICH、 PHICH或 PDCCH , 称为控制区域, 其余符号用来传输 PDSCH , 称为数据区域。 在控制区域, 终端在基站标准带宽 内接收同步信号和 L1/L2层的控制信令, 终端将接收中心频率调整到该基站标 准带宽的中心频率, 将接收滤波器带宽调整为基站标准带宽; 在数据区域, 终端在终端特定标准带宽内接收特定数据, 终端将接收中心频率调整到该终 端特定标准带宽的中心频率, 将接收滤波器带宽调整为终端特定标准带宽。
在 3GPP LTE中, 终端包括两个状态: 空闲状态和激活状态。 在空闲状态, 终端仅需要不时地接收基站的寻呼消息和系统消息等广播消息; 在激活状态, 终端需要接收发送给终端的特定数据。 在空闲状态, 基站发送给终端的广播 消息都在基站标准带宽内传输; 在激活状态, 基站发送给终端的终端特定数 据在终端特定标准带宽内传输。 进一步地, 在接收终端特定数据的子帧, 基 站发送给终端的用于指示终端接收或发送资源消息的 PDCCH , 以及基站的 PHICH, 也可以仅在终端特定标准带宽内传输。 这样, 终端在接收包括系统消 息和寻呼消息的子帧时, 终端在基站标准带宽内接收信号, 终端将接收中心 频率调整到该基站标准带宽的中心频率, 将接收滤波器带宽调整为基站标准 带宽; 终端在接收包括终端特定的数据的子帧时, 终端在终端特定标准带宽 内接收特定数据, 终端将接收中心频率调整到该终端特定标准带宽的中心频 率, 将接收滤波器带宽调整为终端特定标准带宽。
可选地, 如果 PDCCH在终端特定标准带宽内传输, 但用于指示控制区域大 小的 PCFICH需要在基站标准带宽内传输, 则在终端的 PDCCH中, 要包含控制区 i或大小信息, 即控制格式指示 ( CFI , Control Forma t Inf orma t ion )。
可选地, 基站可以分别设定终端特定下行标准带宽和终端特定上行标准 带宽, 终端特定上行标准带宽可以与终端特定下行标准带宽相同, 也可以不 同。 相应地, 基站在所述终端特定下行标准带宽内, 向终端发送终端特定的 数据, 在所述终端特定上行标准带宽内, 接收终端发送的数据。 终端接收终 端下行特定数据时, 将接收中心频率调整到所述终端特定下行标准带宽的中 心频率, 将接收滤波器调整为终端特定下行标准带宽, 接收基站发来的终端 特定的数据。 终端在发射终端特定的上行数据时, 将发射中心频率调整到所 述终端特定上行标准带宽的中心频率, 将发射滤波器调整为终端特定上行标 准带宽, 在所述终端特定上行标准带宽内发送终端特定的上行数据。
进一步地, 基站可以仅设定终端特定下行标准带宽, 仅对下行数据在标 准带宽内进行接收和发送, 但不限定终端上行传输带宽, 即终端可以在基站 传输带宽的任意资源内传输, 这一点并不增加终端的实现复杂度, 因为对于
LTE而言, 在上行发送时, 仅需要关闭部分上行子载波即可不对其他用户造成 干扰。 但基站和终端需要事先约定上行 PUCCH是按照基站传输带宽发送, 还是 按照终端特定上行标准带宽发送。 可选地, 在终端获得基站传输带宽之前, 终端釆用基站标准带宽进行上行发送; 在终端获得基站传输带宽信息之后, 如果设定了终端特定上行标准带宽, 则终端釆用所设定的终端特定上行标准 带宽进行上行发送; 如果没有设定终端特定上行标准带宽, 则终端釆用基站 传输带宽进行发送。
本发明实施例提供的数据传输方法, 基站根据基站传输带宽, 设置基站 标准带宽及终端特定标准带宽, 并将基站标准带宽和终端特定标准带宽的配 置信息通知终端, 在所述基站标准带宽内, 向多个终端发送广播消息, 在所 述终端特定标准带宽内, 基站与特定终端进行数据传输。 与现有技术相比, 基站能够将发送给终端的数据控制在基站传输带宽内的不同标准带宽内, 从 而充分利用基站传输带宽; 同时, 相对一个终端而言, 终端在接收广播消息 时, 釆用基站标准带宽滤波器, 在接收终端特定的数据时, 釆用终端特定带 宽滤波器, 因此终端始终釆用标准带宽接收信号, 从而不会增加终端实现的 复杂度。
