Description

一种传输数据的方法和设备 本申请要求在 2011年 08月 31 日提交中国专利局、 申请号为 201110255903.0、发明名 称为"一种传输数据的方法和设备 "的中国专利申请的优先权, 其全部内容通过引用结合在 本申请中。
技术领域
本发明涉及无线通信技术领域, 特别涉及一种传输数据的方法和设备。
背景技术
对于蜂窝***采用的基本的双工方式, 时分双工 ( Time division duplex, TDD )模式 是指上下行链路使用同一个工作频带, 在不同的时间间隔上进行上下行信号的传输, 上下 行之间有保护间隔(Guard Period, GP ); 频分双工 FDD ( Frequency division duplex, )模 式则指上下行链路使用不同的工作频带, 可以在同一个时刻在不同的频率载波上进行上下 行信号的传输, 上下行之间有保护带宽 (Guard Band, GB )。
长期演进( Long Term Evolution, LTE ) TDD***的帧结构稍复杂一些, 如图 1所示, 一个无线帧长度为 10ms, 包含特殊子帧和常规子帧两类共 10个子帧, 每个子帧为 lms。 特殊子桢分为 3个子帧: 下行导频时隙 (Downlink Pilot Slot, DwPTS )用于传输主同步信 号 (Primary Synchronization Signal, PSS )、 物理下行控制信道( Physical Downlink Control Channel, PDCCH )、 物理混合自动请求重传指示信道 ( Physical HARQ Indication Channel, PHICH ), 物理控制格式指示信道(Physical Control Format Indication Channel, PCFICH )、 物理下行链路共享信道(Physical Downlink Shared Channel, PDSCH )等; GP用于下行和 上行之间的保护间隔); 上行导频时隙 ( Uplink Pilot Slot, UpPTS )用于传输探测用参考信 号( Sounding Reference Signal, SRS ),物理随机接入信道( Physical Random Access Channel, PRACH ) 等。 常规子帧包括上行子帧和下行子帧, 用于传输上行 /下行控制信道和业务数 据等。 其中在一个无线帧中, 可以配置两个特殊子帧 (位于子桢 1和 6), 也可以配置一个特 殊子帧 (位于子帧 1)。 子帧 0和子帧 5以及特殊子帧中的 DwPTS总是用作下行传输, 子帧 2以及特殊子帧中的 UpPTS总是用于上行传输,其他子帧可以依据需要配置为用作上行传 输或者下行传输。
现有***中, 未处于非连续接收(Discontinuous Reception, DRX )状态的用户设备在 每个下行子桢都需要检测基站发送的下行信号, 并根据基站的调度在相应的上行子帧向基 站发送信号。 在 TDD 中, 无线帧中下行子桢和上行子帧的划分比例及对应的位置是基站 通过***广播通知的 , 小区内所有用户设备都按照广播指示的上下行子帧分配方式 (如表 1 所示)进行工作。 现有的 TDD网络部署中, 相邻小区应采用相同的上下行子帧分配方式, 以避免基站与基站之间或者用户设备与用户设备之间的干扰。
Figure imgf000004_0001
现有的无线帧结构仅适用于用户设备和基站之间的信号收发, 对于非用户设备和基站 之间的信号收发并不能很好的支持, 例如用户设备与用户设备之间的直接通信业务, 基站 与基站之间需要通过空中接口直接通信。
综上所述, 目前无线桢结构仅适用于用户设备和基站之间的信号收发, 不能够支持除 用户设备和基站通信之外的其他实体之间的信号收发。

进一步提高了***的资源利用率和***性能。

具体实施方式
针对背景技术中无线桢结构仅适用于用户设备和基站之间的信号收发, 不能支持非用 户设备和基站之间的信号收发的问题, 本发明实施例将无线桢中的子帧分成第一集合和第 二集合, 其中第一集合的子帧用于基站和用户设备之间通信; 第二集合的子帧用于其他用 途的通信, 比如用户设备之间的通信, 基站之间的通信等。 由于将无线帧中的子帧分成不 同用途的两种集合, 从而在适用于用户设备和基站之间的信号收发的前提下, 能够支持除 用户设备和基站通信之外的其他实体之间的信号收发, 比如用户设备和除基站之外的实体 之间的信号收发, 基站和除用户设备之外的实体之间的信号收发。
其中, 本发明实施例的方案适用于 FDD***和 TDD***。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图 2所示, 本发明实施例用户设备传输数据的方法包括下列步骤:
步骤 201、 用户设备确定无线帧中属于第一集合的子帧以及属于第二集合的子帧; 步骤 202、 用户设备通过第一集合中的子帧与驻留小区基站进行通信, 以及通过第二 集合中的子帧与除驻留小区基站之外的实体进行通信。
其中, 除驻留小区基站之外的实体包括其他的用户设备和除驻留小区基站之外的其他 基站。 由于将无线帧中的子桢分成不同用途的两种集合, 从而在适用于用户设备和基站之间 的信号收发的前提下, 能够支持用户设备和除基站之外的实体之间的信号收发, 比如用户 设备和用户设备之间的信号收发。
较佳地, 在实施中可以预先设置一定的时间段, 比如 5个无线帧, 则用户设备确定 5 个无线桢中属于第一集合的子幀以及属于第二集合的子桢, 后续的无线帧按照现有技术通 信。
具体的时间段可以根据仿真或需要进行设定。 较佳地, 可以在协议中规定, 也可以由 网络側通知。
在通信时, 用户设备根据需要可以在同一个无线帧中的第一集合和第二集合的子帧上 分别与驻留小区基站进行通信和除驻留小区基站之外的实体进行通信, 比如属于同一个无 线帧的子帧 3和子帧 4, 子帧 3属于第一集合, 子帧 4属于第二集合, 则用户设备可以在 子帧 3上与驻留小区基站进行通信, 在子帧 4上与除驻留小区基站之外的实体进行通信; 用户设备才艮据需要可以在不同无线帧中的第一集合和第二集合的子帧上分别与驻留 小区基站进行通信和除驻留小区基站之外的实体进行通信, 比如属于不同无线桢的子帧 3 和子桢 4, 子帧 3属于第一集合, 子帧 4属于第二集合, 则用户设备可以在子帧 3上与驻 留小区基站进行通信, 在子帧 4上与除驻留小区基站之外的实体进行通信。
在通信时, 用户设备与驻留小区基站进行通信的数据, 和与除驻留小区基站之外的实 体进行通信的数据可以相同也可以不同。
比如根据业务需要用户设备可以将与驻留小区基站进行通信的数据转发给其他用户 设备或其他基站。 具体的, 用户设备将通过第一集合中的子桢与驻留小区基站进行通信的 数据, 通过第二集合中的子帧转发给与除驻留小区基站之外的实体。
在实施中, 可以一个子帧同时属于两个集合; 较佳地, 每个子帧只属于一个集合。 其中, 本发明实施例的用户设备是演进的用户设备, 其中演进的用户设备是演进的 TDD用户设备及支持本发明方案的功能的用户设备, 比如版本 3GPP LTE Rel-l l或后续版 本的用户设备。 驻留小区基站就是指用户设备的服务小区所属的基站。
步骤 201中, 用户设备根据收到的来自网络侧的配置信息, 确定无线帧中属于第一集 合的子桢以及属于第二集合的子帧。
较佳地, 用户设备通过***广播或用户设备专属信令接收配置信息。
若用户设备通过用户设备专属信令接收配置信息, 则不同的用户设备对应的配置信息 可以全部相同或部分相同或全不相同。
其中, 第一集合中的子帧分为上行子帧和下行子帧, 分别用于用户设备和网络侧之间 的上行和下行信号收发。 在 TDD ***中, 下行子帧和上行子桢位于同一载波中, 子帧方 向的划分方式可以由网络通知给用户设备, 例如通过***广播或者用户设备专属的控制信 令等方式通知。 如果通过用户设备专属的控制信令等方式通知, 则不同的用户设备可以被 配置为不同的子帧方向划分方式。 具体的, 步骤 201中, 用户设备根据收到的来自网络侧 的配置信息, 确定第一集合中的上行子帧和下行子帧。
较佳地, 步骤 202中, 用户设备在第一集合中的上行子帧上发送信号, 以及在第一集 合中的下行子帧上接收信号。
其中, 第二集合中的子桢分为处于发送状态的子帧和处于接收状态的子帧。 在 TDD ***中, 处于发送状态的子帧和处于接收状态的子帧位于同一载波中, 子帧状态的划分方 式可以由网络通知给用户设备, 例如通过***广播或者用户设备专属的控制信令等方式通 知。 如果通过用户设备专属的控制信令等方式通知, 则不同的用户设备可以被配置为不同 的子桢状态划分方式。 具体的, 步驟 201中, 用户设备根据收到的来自网络侧的配置信息, 确定第二集合中的处于发送状态的子帧和处于接收状态的子帧。
较佳地, 步骤 202中, 用户设备在第二集合中处于发送状态的子帧上发送信号, 以及 在第二集合中处于接收状态的子帧上接收信号。
具体的, 用户设备在第二集合中处于发送状态的子帧上向其他用户设备发送信号, 且 不在处于发送状态的子桢上向基站发送信号; 以及在第二集合中处于接收状态的子帧上接 收来自其他用户设备的信号, 且不在处于接收状态的子帧上接收基站的信号。
例如: 用户设备与用户设备直接通信时, 在这些子帧中用户设备可不接收来自于基站 的信号, 也不向基站发送信号, 用户设备根据基站的信令配置处于发送或者接收状态, 不 同的用户设备在同一子桢可以被配置为相同或不同的状态。 在发送状态时, 用户设备发送 用于用户设备之间直接通信的控制信令、 数据信号以及相应的信道测量和解调参考信号 等, 以及用于其他用户设备捕获本用户设备的参考信号或同步信号等; 在接收状态时, 用 户设备可检测其他一个或多个用户设备的发送的同步信号或参考信号, 用于发现相应的用 户设备存在以及与相应的用户设备建立同步, 此外, 还可接收相应用户设备发送的控制信 令、 数据信号以及相应的测量和解调参考信号等。
较佳地, 用户设备在利用第二集合中的子帧进行其他用途的通信(比如用户设备之间 的通信)时, 可以用完整的子帧, 例如 LTE***中时间长度为 1ms, 频域宽度为***带宽; 也可以用一个子帧的一部分,例如一个完整子帧中部分的时间长度 (例如 LTE中部分 OFDM ( Orthogonal Frequency Division Multiplexing, 正交频分复用)符号)以及部分的频域宽度 (例如 LTE中部分资源块( Resource Block, RB ) )。
如图 3所示, 本发明实施例基站传输数据的方法包括下列步骤:
步骤 301、 基站确定无线帧中属于第一集合的子帧以及属于第二集合的子桢; 步骤 302、 基站通过第一集合中的子帧与驻留在本基站小区的用户设备进行通信, 以 及通过第二集合中的子桢与除驻留在本基站小区的用户设备之外的实体进行通信。 除驻留在本基站小区的用户设备之外的实体包括其他基站和非驻留在本基站小区的 用户设备。
由于将无线帧中的子桢分成不同用途的两种集合, 从而在适用于用户设备和基站之间 的信号收发的前提下, 能够支持基站和除用户设备之外的实体之间的信号收发, 比如基站 和基站之间的信号收发。
较佳地, 在实施中可以预先设置一定的时间段, 比如 5个无线帧, 则基站确定 5个无 线帧中属于第一集合的子桢以及属于第二集合的子帧, 后续的无线帧按照现有技术通信。
具体的时间段可以根据仿真或需要进行设定。 较佳地, 可以在协议中规定, 也可以由 网络側 (比如高层)通知。
在通信时, 基站根据需要可以在同一个无线桢中第一集合和第二集合的子桢上分别与 驻留在本基站小区的用户设备进行通信和除驻留在本基站小区的用户设备之外的实体进 行通信, 比如属于同一个无线帧的子帧 3和子帧 4, 子帧 3属于第一集合, 子幀 4属于第 二集合, 则基站可以在子桢 3上与驻留在本基站小区的用户设备进行通信, 在子桢 4上与 除驻留在本基站小区的用户设备之外的实体进行通信;
基站根据需要可以在不同的无线帧中的第一集合和第二集合的子帧上分别与驻留在 本基站小区的用户设备进行通信和除驻留在本基站小区的用户设备之外的实体进行通信 , 比如属于不同无线帧的子帧 3和子帧 4, 子帧 3属于第一集合, 子帧 4属于第二集合, 则 基站可以在子帧 3上与驻留在本基站小区的用户设备进行通信 , 在子帧 4上与除驻留在本 基站小区的用户设备之外的实体进行通信;
在通信时, 基站与驻留在本基站小区的用户设备进行通信的数据, 和与除驻留在本基 站小区的用户设备之外的实体进行通信的数据可以相同也可以不同。
比如根据业务需要基站可以将与本基站小区的用户设备进行通信的数据转发给其他 用户设备或其他基站。 具体的, 基站将通过第一集合中的子帧与驻留在本基站小区的用户 设备进行通信, 通过第二集合中的子帧转发给除驻留在本基站小区的用户设备之外的实 体。
在实施中, 可以一个子帧同时属于两个集合; 较佳地, 每个子帧只属于一个集合。 其中, 驻留在本基站小区的用户设备是指基站管理的小区中的用户设备。
步骤 302中, 基站通过第一集合中的子桢与驻留在本基站小区的用户设备进行通信 , 这里的驻留在本基站小区的用户设备包括演进的用户设备和非演进的用户设备。
其中, 演进的用户设备是演进的 TDD用户设备及支持本发明方案的功能的用户设备 , 比如版本 3GPP LTE Rel-11或后续版本的用户设备。
较佳地, 步骤 302中, 基站通过第二集合中的子帧与驻留在本基站小区的非演进用户 设备进行通信。 在实施中, 基站可以根据网络侧的配置信息确定无线帧中属于第一集合的子桢以及属 于第二集合的子帧, 还可以自己确定无线帧中属于第一集合的子帧以及属于第二集合的子 帧。
如果基站才 据网络侧的配置信息确定无线帧中属于第一集合的子帧以及属于第二集 合的子桢, 则步骤 301中, 基站根据收到的来自网络侧(比如高层) 的配置信息, 确定无 线帧中属于第一集合的子桢以及属于第二集合的子帧。
其中, 不同的基站对应的配置信息全部相同或部分相同或全不相同。
如果由基站确定无线桢中属于第一集合的子帧以及属于第二集合的子帧, 则基站根据 业务需求确定属于第一集合的子帧以及属于第二集合的子帧; 4艮据上下行配置比例确定第 一集合中子帧的传输方向, 以及根据需要传输的业务, 确定第二集合中子帧的传输方向。
比如若进行 D2D的业务比较多,则可以在第二集合多配置一些子帧;若基站和用户设 备的业务比较多, 则可以在第一集合多配置一些子帧。
比如上下行配置比例为 1 : 3 , 则正好或近似按照 1 : 3对第一集合中的子帧进行配置。 比如 D2D业务中, 若用户设备 A和 B之间传输, 并且传输的数据量差不多, 则第二 集合中可以配置处于发送状态和处于接收状态的子帧比例差不多;若用户设备 A和 B之间 传输, 并且用户设备 A发送的数据比较多,则第二集合中可以为用户设备 A配置较多的处 于发送状态的子帧, 而用户设备 B配置较多的处于接收状态的子帧。
其他情况与上述情况类似, 在此不再赘述。
在实施中, 若由网络侧进行配置, 则网络側在配置时也可以按照上述基站的方式确定 属于第一集合的子帧以及属于第二集合的子桢。
较佳地, 基站根据确定的第一集合和第二集合生成配置信息, 并通过***广播或用户 设备专属信令, 发送配置信息。
如果基站通过用户设备专属信令发送配置信息, 则不同的用户设备对应的配置信息可 以全部相同或部分相同或全不相同。
其中, 第一集合中的子帧分为上行子帧和下行子帧, 分别用于基站和用户设备之间的 上行和下行信号收发。
具体的, 基站在第一集合中的上行子帧上接收信号, 以及在第一集合中的下行子帧上 发送信号。
其中, 第二集合中的子帧分为处于发送状态的子帧和处于接收状态的子帧。 具体的, 基站在第二集合中处于发送状态的子帧上发送信号, 以及在第二集合中处于接收状态的子 帧上接收信号。
若基站与其他基站进行通信, 则基站在第二集合中处于发送状态的子帧上向其他基站 发送信号, 且不在处于发送状态的子帧上向用户设备发送信号; 以及在第二集合中处于接 收状态的子帧上接收来自其他基站的信号, 且不在处于接收状态的子帧上接收用户设备的 信号。
例如: 基站与基站直接通信时, 这些子桢中基站可不接收用户设备发送的信号, 也不 向用户设备发送信号, 基站根据网络的配置处于发送或者接收状态, 不同的基站在同一子 帧可以被配置为相同或不同的状态。 在发送状态时, 基站发送用于基站之间直接通信的控 制信令、 数据信号以及相应的测量或解调参考信号等, 以及用于其他基站捕获本基站的参 考信号或同步信号等; 在接收状态时, 基站可检测其他一个或多个基站发送的同步信号或 参考信号, 用于与相应的基站建立同步。 此外, 还可接收相应基站发送的控制信令、 数据 信号以及相应的测量和解调参考信号等。
较佳地, 基站还可以在确定的第二集合的子桢上, 为非演进的用户设备配置为上行子 帧。
较佳地, 基站还可以不调度非演进的用户设备在第二集合的子帧上发射信号。
下面以一个具体实例对用户设备采用第二集合传输信号进行说明。
如图 4所示, 在 TDD***中 , 演进的用户设备 1和 2分別 站配置了 2个集合, 第一集合为一个无线桢中的子桢 {0,1,2,5,6,7} , 第二集合为一个无线帧中的子帧 {3,4,8,9}。 对于演进的用户设备 1 , 处于接收状态的子帧是第二集合的子帧 {3,8} , 处于发送状态的子 帧是第二集合的子帧 {4,9}; 对于演进的用户设备 2, 处于接收状态的子帧是第二集合的子 帧 {4,9} , 处于发送状态的子帧是第二集合的子帧 {3,8}。
在处于接收状态的子桢上, 演进的用户设备 1和 2不接收和处理基站的信号, 而用于 与其他演进的用户设备袭得同步、 接收来自于其他演进用户设备的控制信令和数据以及参 考信号等;
在处于发送状态的子帧上, 演进的用户设备 1和 2不向基站发送信号, 而是向其他演 进用户设备发送同步信号, 控制信令和数据信号以及参考信号等。

在处于接收状态的子桢上, 演进基站 1和演进基站 2不向终端发送信号, 而是发送针 对其他基站的同步信号、 控制信令、 数据信号与参考信号等;
在处于发送状态的子桢上, 演进基站 1和演进基站 2不接收终端发送的信号, 而是接 收和处理其他基站发射的同步信号、 控制信令、 数据信号和参考信号等。 此外, 第二集合中的子帧上, 基站仍可配置演进终端之间进行直接通信, 具体参见图
4。
对于非演进终端, 按照现有技术方式与基站进行上行和下行的信号传输, 在演进终端 配置为第二集合的子帧上, 基站为非演进终端分配为上行传输和 /或不调度非演进的用户 设备在第二集合的子帧上发射信号。
