Description
用户设备传输数据的控制方法和系统
技术领域
本发明涉及通信领域, 尤其涉及一种用户设备传输数据的控制方法和系 统。
背景技术
长期演进( LTE, Long Term Evolution ) 系统中有两种帧结构 , 帧结构类 型 1适用于全双工和半双工 (FDD, Frequency Division Duplex ) 。 每个无线 帧长为 10ms, 由 20个时隙 (slot )组成, 每个时隙 0.5ms, 编号从 0到 19。 一个子帧( subframe )由两个连续的时隙组成, 如子帧 i由两个连续的时隙 2i 和 2i+l组成。 无论是半双工 FDD还是全双工 FDD, 上下行都是在不同的频 率上传输, 但是对于半双工 FDD, UE不能同时发送和接收数据; 而对于全 双工 FDD就没有这个限制, 即在每 10ms间隔内可以有 10个下行和 10个上 行子帧。 如图 1所示; 帧结构 Type 2 适用于时分双工 (TDD, Time Division Duplex ) 。 一个无线帧长度为 10ms, 由两个长度为 5ms的半帧 (half-frame ) 组成。 一个半帧由 5个长度为 1ms子帧组成。 支持的上下行链路配置如表 1 所示, 表中" D"表示该子帧为下行子帧, "U"表示该子帧为上行子帧, "S"表 示该子帧为特殊子帧( special subframe )。特殊子帧由 DwPTS, GP以及 UpPTS 组成, 总长度为 lms。 每个子帧 i由两个长度为 0.5ms ( 15360 Ts ) 的时隙 2i和 2i+l组成, 如图 2所示。
帧结构 Type 2 支持 5ms和 10ms两种下行-上行转换周期。 在 5ms的上 下行转换周期中, 两个半帧都有特殊子帧。 在 10ms的上下行转换周期中, 只 有第一个半帧有特殊子帧。子帧 0、5 和 DwPTS 总是预留为下行传输。 UpPTS 和紧接着特殊子帧的下一个子帧总是预留为上行传输。 因此对 5ms的上下行 转换周期, UpPTS、 子帧 2和子帧 7预留为上行传输; 对 10ms的上下行转换 周期, UpPTS、 子帧 2预留为上行传输;
表 1 : 上下行链路配置.
LTE中定义了如下三种下行物理控制信道: 物理下行控制格式指示信道 ( PCFICH, Physical Control Format Indicator Channel ); 物理混合自动重传请 求才旨示信道 ( PHICH , Physical Hybrid Automatic Retransmission Request Indicator Channel ) ; 物理下行控制信道 ( PDCCH, Physical Downlink Control Channel ) 。
其中, PCFICH承载的信息用于指示在一个子帧里传输 PDCCH的正交频 分复用 ( OFDM, Orthogonal Frequency Division Multiplexing )符号的数目 , 在子帧的第一个 OFDM符号上发送, 所在频率位置由系统下行带宽与小区标 识(ID, Identity )确定。 信息。 PHICH的数目、时频位置可由 PHICH所在的下行载波的物理广播信道 ( PBCH, Physical Broadcast Channel ) 中的系统消息和小区 ID确定。
PDCCH用于承载下行控制信息 (DCI, Downlink Control Information ) , 包括: 上行 PUSCH的调度信息、 下行 PDSCH的调度信息, 以及上行功率控 制信息。
DCI的格式( DCI format )分为以下几种: DCI format 0、 DCI format 1、 DCI format 1A、 DCI format 1B、 DCI format 1C、 DCI format 1D、 DCI format 2、 DCI format 2A、 DCI format 3和 DCI format 3 A等; 其中:
DCI format 0 用于指示物理上行共享信道 ( Physical Uplink Shared Channel, 简称为 PUSCH ) 的调度;
DCI format 1、 DCI format 1A、 DCI format 1B、 DCI format 1C、 DCI format ID用于一个 PDSCH码字调度的不同模式; DCI format 2、 DCI format 2A、 DCI format 2B用于空分复用的不同模式;
DCI format 3、 DCI format 3A用于物理上行控制信道 ( Physical Uplink Control Channel, 简称为 PUCCH )和 PUSCH的功率控制指令的不同模式。
发明内容
在 LTE和 LTE-A网络中, 两个 UE通过基站彼此进行通讯, 然而, 为了 更有效的使用网络资源和对于新的服务模式的需求导致设备和设备 ( D2D ) 之间的通讯越来越引起人们的关注。 D2D通讯、 移动台到移动台、 端到端、 点到点通讯都将在移动通讯网络中应用。距离较近的设备之间 D2D通讯代替 了传统的源设备经过基站传递数据到目标设备的传输方式。 在通讯网络中, D2D通讯使用无线资源进行通讯, 共享设备与基站通讯的无线链路, 这对于 基站无限资源的管理带来新的问题, 对于原有网络中的通讯质量产生影响, 因此, 本发明提供了一种设备之间通讯方式, 使得设备之间的通讯对原有通 讯系统兼容, 解决设备间的通讯和原有网络中通讯的干扰问题, 提高频语效 率。

为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图及具体 实施例对本发明作进一步的详细描述。 需要说明的是, 在不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
需要说明的是, 本文所说的基站包括 NodeB、 eNode B、 Home eNodeB、 pico eNodeB、 Relay等设备中一种或多种。
对于基站:
基站发送用于指示第一用户设备( UE1 )向第二用户设备 ( UE2 )发送数 据的控制信息。
当发送给 UE1和 UE2时, 具体的发送方式有两种:
第一种,所述基站向第一用户设备和第二用户设备发送同一条控制信息; 第二种, 所述基站向第一用户设备发送一条控制信息, 向所述第二用户 设备发送另一条控制信息。
在实际应用中, 上述控制信息可以直接复用现有技术中用来控制基站与 用户设备之间数据传输的控制信息, 即在实际应用中, 通过发送一条控制信 息, 该控制信息是用来控制基站与用户设备之间数据传输的, 或者是用来控 制两个用户设备之间数据传输的。 而区别该两种传输场景的方法具体如下: 所述基站通过无线网络临时标识(Radio Network Temporary Identifier, RNTI )、 信令或控制信息的格式来指示第一用户设备向第二用户设备发送数
据。
具体来说, 由于基站能够控制用户设备与基站的通信, 也能控制用户设 备之间的通信, 为了达到区分控制信息是用来控制那两个设备之间的传输, 本发明提出如下方案:
方案一: 所述基站通过在所述控制信息使用不同的无线网络临时标识
( RNTI )来区分所述控制信息是用来控制基站与用户设备之间的数据传输的 还是用来控制两个用户设备之间的数据传输的;
例如, 对于一用户设备 UE1而言, 有两种场景的数据传输, 分别是 UE1 与基站之间的通信, UE1和 UE2之间的通信,可以预先配置为 UE1配置两个 RNTI, 如 RNTI-1和 RNTI-2, 设置 RNTI-1是在基站控制 UE1与基站进行数 据传输时使用的 RNTI, 而 RNTI-2是用来控制 UE1与其他 UE之间进行数据 传输时使用的 RNTI。 当进行用户设备之间数据传输时, 基站发送给 UE1的 控制信息中 RNTI为 RNTI-2, UE1通过解析, 就可以知道需要进行用户设备 之间的数据传输。
需要说明的是, 在方案一中, 如果基站向 UE1和 UE2发送同一条消息, 则基站所使用的 RNTI应是 UE1和 UE2共用的 RNTI; 如果基站向 UE1发送 一条控制信息, 向 UE2发送另一条控制信息, 则所述控制信息对应的 RNTI 是 UE专有的无线网络临时标识或 UE1和 UE2共用的 RNTI。
方案二: 在所述控制信息中使用相同的无线网络临时标识时, 所述基站 通过在控制信息中发送的不同的信令来区分所述控制信息是用来控制基站与 用户设备之间的数据传输的还是用来控制两个用户设备之间的数据传输的; 此处, 仍以上例进行说明, 以 UE1的两种传输场景均使用相同的 RNTI 为例进行说明。 基站可以在控制信息中携带不同的信令信息来完成传输场景 的区分, 例如, 在控制信息中携带不同的信息、 专有信令标识。对 UE1而言, 专用信令标识 A表示基站和 UE1之间数据传输,专用信令标识 B表示 UE之 间的数据传输。
需要说明的是,在方案二中,如果基站向 UE1和 UE2发送同一条控制信 息, 则基站所使用的 RNTI应是 UEl和 UE2共用的 RNTI; 如果基站向 UE1
发送一条控制信息,向 UE2发送另一条控制信息,则所述控制信息中的 RNTI 是 UE专有的无线网络临时标识或 UE1和 UE2共用的 RNTI。
方案三: 在所述控制信息中使用相同的无线网络临时标识时, 所述基站 通过发送不同控制信息格式类型来区分所述控制信息是用来控制基站与用户 设备之间的数据传输的还是用来控制两个用户设备之间的数据传输的;
此处, 仍以上例进行说明, 以 UE1的两种传输场景均使用相同的 RNTI 为例进行说明。 基站还可以通过不同的控制信息格式来区分, 例如: DCI Format类型, DCI Format A表示基站和 UE1之间数据传输, DCI Format B表 示 UE1之间的数据传输。
需要说明的是,在方案三中,如果基站向 UE1和 UE2发送同一条控制信 息, 则基站所使用的 RNTI应是 UEl和 UE2共用的 RNTI; 如果基站向 UE1 发送一条控制信息,向 UE2发送另一条控制信息,则所述控制信息中的 RNTI 是 UE专有的无线网络临时标识或 UE1和 UE2共用的 RNTI。
其中 UE 专有的无线网络临时标识可以是小区无线网络临时标识 ( C-RNTI )等。
通过如上的内容可知, 通过对控制信息的管理, 解决了设备间的通讯和 原有网络中通讯的干扰问题。
其中, 所述控制信息承载在介质介入控制层控制单元中、 物理下行控制 信道上或者无线资源控制协议(Radio Resource Control, RRC ) 配置信令中。
所述控制信息还包括物理资源位置、 功率控制信息、 调制编码方式
( MCS )、 进程号、预编码以及数据解调导频循环移位量中一种或多种信息。
通过基站调度设备之间通讯的物理资源, 触发了用户设备之间的直接通 信, 实现了设备之间的直接通信。
对于第一用户设备:
第一用户设备接收用于指示所述第一用户设备向第二用户设备发送数据 的控制信息;
所述第一用户设备根据所述控制信息, 向所述第二用户设备发送数据。 其中,所述第一用户设备使用第一用户设备和第二用户设备共用的 RNTI
向所述第二用户设备发送数据,从而保证以简单的方式实现 UE1和 UE2在数 据传输过程中信息的加解扰。
而所述第一用户设备通过上行子帧、 下行子帧或特殊子帧向所述第二用 户设备发送数据, 其中, 所述特殊子帧为预先设置的专用于用户设备之间数 据传输的传输单元。
其中, 所述特殊子帧为预先设置的专用于用户设备之间数据传输的传输 单元, 该特殊子帧可以是对预留的传输资源划分得到的, 而该预留的传输资 源也可以是从上行子帧和下行子帧中至少一个截取的部分资源。
