Description

非连续发送的方法、 用户设备和网络侧设备 技术领域
本发明实施例涉及无线通信领域, 并且更具体地, 涉及非连续发送的方 法、 用户设备和网络侧设备。 背景技术
随着第三代合作伙伴项目 ( the 3rd Generation Partnership Project, 3GPP ) 在标准中对小区前向接入信道( Cell Forward Access Channel, CELL_FACH ) 状态的持续增强, 原来需要在小区专有信道 ( Cell Dedicated Channel, CELL_DCH )状态承载的部分分组业务也可以在 CELL_FACH状态进行。 由 此引入的 CELL_FACH 公共增强专用信道 ( common Enhanced Channel, common E-DCH )特性使得 CELL_FACH状态的上行分组数据传输性能得到 增强, 使其获得较小的分组传输时延和较高的传输速率。
然而, 目前 CELL_FACH状态下分组业务的数据传输是断续进行的, 在 一次交互过程中可能进行^艮多次的数据断续传输, 并且无论在有无数据传输 的情况下, 用户设备 UE都保持同样的连接状态, 占用同样的资源。 而且 UE 在占用资源且没有数据传输时, 上行的专用物理控制信道(Dedicated Physical Control Channel, DPCCH )会继续发送功率控制、 导频信号等控制 信息, 这样会带来对其他用户的上行干扰, 使得系统容量受到限制。 发明内容

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。
本发明的技术方案, 可以应用于各种通信系统, 例如: 全球移动通信系 统( GSM, Global System of Mobile communication ), 码分多址( CDMA, Code Division Multiple Access ) 系统, 宽带码分多址( WCDMA, Wideband Code Division Multiple Access Wireless ),通用分组无线业务( GPRS , General Packet Radio Service ) , 通用移动通信系统 (UMTS , Universal Mobile Telecommunications System ), 长期演进 ( LTE, Long Term Evolution )等。
用户设备 ( UE , User Equipment ) , 也可称之为移动终端 ( Mobile Terminal ),移动用户设备等, 可以经无线接入网(例如, RAN, Radio Access Network )与一个或多个核心网进行通信, 用户设备可以是移动终端, 如移 动电话(或称为"蜂窝"电话)和具有移动终端的计算机, 例如, 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, 它们与无线接入 网交换语言和 /或数据。

网络侧设备,可以是 UMTS中的无线网络控制器(RNC, Radio Network controller ), 也可是 RNC与基站的合称, 还可以是 LTE中的 eNB, CSM中 的基站控制器(BSC, Base Station Controller )等设备, 本发明并不限定。
图 1是本发明一个实施例的非连续发送的方法的流程图。 图 1的方法由 UE执行。
101 , 用户设备 UE接收网络侧发送的非连续发送 DTX配置信息。
102, 在 UE处于非专用连接态时, UE根据 DTX配置信息确定专用物 理控制信道 DPCCH的发送图样。
103, UE根据发送图样向 UE的服务基站发送 DPCCH。
本发明实施例通过在非专用连接态下对 DPCCH进行非连续发送, 从而 能够降低对其他用户的上行干扰, 提高系统容量。
其中, 非专用连接态是相对于 CELL_DCH 状态而言的, 可以包括 CELL_FACH状态、 CELL_PCH状态、 URA_PCH状态、 空闲 idle状态等, 本发明实施例以 CELL_FACH为例进行说明。
可选地, 作为一个实施例, 步骤 102之前还可以包括: 通过无线资源控 制 RRC专用信令向网络侧发送 UE的非专用连接态的 DTX能力信息; 或者 通过 RRC专用信令向网络侧发送 UE的小区专用信道 CELL_DCH状态的 DTX能力信息, 以便于网络侧沿用 UE的 CELL_DCH状态的 DTX能力信 息作为 UE的非专用连接态的 DTX能力信息, 其中 UE的非专用连接态的 DTX能力信息用于向网络侧指示 UE支持非专用连接态的 DTX。 也就是说, UE上报非专用连接态的 DTX能力信息可以在步骤 101之前,或步骤 101之 后。
具体地, UE向网络侧发送 DTX能力信息可以通过无线资源控制 RRC 专用信令向网络侧上报 DTX能力信息。
例如, 用于上报 DTX能力信息的 RRC专用信令可以为 RRC连接建立 完成 (RRC connection setup complete), 小区更新 ( Cell Update )、 UTRAN注 册区更新(UTRAN Registration Area Update, URA Update ), RRC连接请求 ( RRC connection request )等信令。
进一步地,还可以沿用 UE在 CELL_DCH状态的 DTX能力信息作为非 专用连接态的能力指示, 例如 CELL_FACH状态的 DTX能力信息, 即可以 通过 UE支持小区专用信道 CELL_DCH状态的 DTX的信令向网络侧上报 DTX能力信息, 也就是说: 只要支持非专用连接态的 DTX的 UE上报了支 持 DPCCH Discontinuous Transmission support (该 IE当前用于指示 UE支持 CELL_DCH DTX的指示;), 就代表该 UE同时支持非专用连接态的 DTX和 专用连接态的 DTX。
进一步地,通过 UE支持小区专用信道 CELL_DCH状态的 DTX的信令 向网络侧上报 DTX 能力信息还需要 UE 的版本信息, 如果 UE 支持 CELL_DCH状态的 DTX, 同时该 UE支持 common E-DCH, 则可以根据 UE 的版本信息判断该 UE是否支持 CELL_FACH状态的 DTX。 在这种情况下, UE支持 CELL_FACH状态的 DTX和 UE支持 CELL_DCH状态的 DTX的能 力上报可以采用同一个信元( Information Element, IE )。
可选地, 作为一个实施例, 步骤 101可以包括: 通过系统广播接收 DTX 配置信息; 或者通过 RRC专用信令接收 DTX配置信息; 或者接收并沿用 CELL_DCH状态的 DTX配置信息。
其中, 接收并沿用 CELL_DCH状态的 DTX配置信息, 包括: UE接收 网络侧通过系统广播或者 RRC专用信令发送的用于指示 UE沿用小区专用 信道 CELL_DCH状态的全部或者部分 DTX配置信息的指令; 或者 UE接收 CELL_DCH状态的 DTX配置信息, 并通过网络侧和 UE预先约定的方式, 沿用 CELL_DCH状态的全部或者部分 DTX配置信息作为非专用连接态的 DTX配置信息。
其中, CELL_DCH状态的 DTX配置信息可以是在 UE由 CELL_DCH 状态转入非专用连接态之前接收到并存储在 UE本地的, 转入非专用连接态 后 UE可以直接沿用该 DTX配置信息。
具体地, 网络侧可以在系统信息块( System Information Block , SIB )中 写入 DTX配置信息, 并通过系统广播的方式向 UE发送。 或者可以通过例 如小区更新确认( Cell Update Confirm ), 物理信道重配置( Physical Channel
Reconfiguration ) , 无线 载重酉己置 ( Radio Bearer Reconfiguration ), Radio Bearer Setup等 RRC专用信令携带 DTX配置信息。 进一步地, 所述系统广 播消息或者 RRC专用信令中也可以由网络侧下发一个沿用指示, 或者通过 约定, 使得 UE沿用 CELL_DCH状态的 DTX配置信息来作为 CELL_FACH 状态的 DTX配置信息。
可选地,作为一个实施例, DTX配置信息可以包括:第一 DTX周期(UE
DTX cycle 1 );第一 DTX周期中的 DPCCH发送长度( UE DPCCH burst— 1 ); 用于指示不同的公共增强专用信道 common E-DCH资源配置所对应的 DTX 偏置的资源 DTX偏置参数(Resource DTX offset )。 上述配置信息配置了 具有一个周期的 DTX参数, 其中 common E-DCH资源是在 SIB中配置的, 一个小区目前最多可以配置 32套资源,每套资源都对应于一个资源 DTX偏 置参数, 也就是说, 竟争到不同资源的 UE会错开非连续发射的时间, 从而 能够进一步的降低上行干扰, 使得不同的用户的功率在时域上呈现均匀分 布, 增加用户数量, 从而进一步地提高了系统容量。
可选地, 作为一个实施例, DTX 配置信息还可以包括以下参数: 第二 DTX周期 ( UE DTX cycle 2 ); 第二 DTX周期中的 DPCCH发送长度( UE DPCCH burst— 2 ); 启动第二 DTX周期的时间 ( Inactivity Threshold for UE DTX cycle 2 )。 用于配置第二个 DTX周期, 可以使得非连续传输到一定时 间后变换发送周期。 如果第二周期为第一周期的整数倍, UE以第一 DTX周 期发送一段时间后, 使用更长的第二 DTX周期发送, 可以更进一步的降低 上行干扰。
此外, DTX 配置信息还可以包含一些其他的参数, 例如媒体访问控制 MAC层 DTX的周期( MAC DTX cycle )、 UE进入 MAC DTX的门限( MAC Inactivity Threshold )以及 UE在有数据需要发送时提前发送 DPCCH的时间 ( UE DTX long preamble length )等。
可选地, 作为一个实施例, 步骤 102包括: 在 UE占有 common E-DCH 资源, 且没有数据传输时, 根据 DTX配置信息确定发送 DPCCH的帧号和 子帧号, 并且在 DPCCH 发送的帧号和子帧号所对应的时间点上发送 DPCCH。 具体地, 处于 CELL_FACH状态的 UE有上行数据传输时, 该 UE 需要竟争 common E-DCH资源, 并采用该资源发送上行数据。 在数据发送 的间歇时间段, 或者数据发送完的一段时间里, 数据信道 E-DPDCH不再发 送, 但是控制信道 DPCCH会继续发送, 此时 UE需要通过以下公式来计算 DPCCH发送的图样( Pattern ), 即 DPCCH非连续发送的一系列的发送时间 点:
((5*CFN - DTX—Offset + S) MOD DTX_cycle) = 0
其中, CFN为连接帧号 ( Connection Frame Number ), S为一个连接帧 中的子帧号。其中 DTX_cycle和 DTX_offset可以为上述实施例中 DTX配置 信息中的参数第一 DTX周期和资源 DTX偏置, MOD为取模运算。 通过上 述公式可以计算出一系列的发送时间点, 从而组成 DPCCH的发送 pattern。 更进一步地, UE还可以采用两个周期来计算 DPCCH的发送 pattern, 仍旧 采用上述公式, 其中 DTX_cycle为上述实施例中 DTX配置信息中的参数第 二 DTX周期。
可选地, 作为一个实施例, 上述方法还可以包括: UE通过随机接入参 数向服务基站发送 UE的非专用连接态的 DTX能力信息, UE的非专用连接 态的 DTX能力信息用于向服务基站指示 UE支持非专用连接态的 DTX, 随 机接入参数包含接入签名、 物理随机接入信道 PRACH信道化码和接入子信 道中的至少一种。 此外, 也可以由 RNC向服务基站通知 UE的 DTX能力信 息,较为优选的,在 RNC获得 UE支持非专用连接态的 DTX能力之后, RNC 可以通过 HS-DSCH DATA FRAME指示 NodeB该 UE支持非专用连接态的 DTX。
进一步地, UE接收服务基站发送的高速共享控制信道 HS-SCCH命令, 以便于激活 /去激活 UE的非专用连接态的 DTX。
UE的服务基站可以控制 UE的 DTX的激活和去激活。 具体地, 服务基 站首先需要获取 UE的 DTX能力信息,之后才能针对支持该能力的 UE下发 激活 /去激活指示。 其中, UE可以在随机接入时通过随机接入参数来指示该 UE是否支持 CELL_FACH DTX, 或者, 由于上述实施例中, UE可以上报
FP ) 中通知该服务基站关于 UE支持 CELL_FACH DTX的信息。 之后, 服 务基站可以通过 HS-SCCH order对 UE的 DTX进行激活 /去激活控制。 更进 一步地, 服务基站除了采用单对单的方式激活 /去激活 UE 的 CELL_FACH DTX, 服务基站还可以分组的方式实现激活 /去激活, 或者以整个小区为单 位来进行 CELL_FACH DTX的激活 /去激活。 进一步地, 基站在对整个小区 的用户的 DTX激活 /去激活时可以采用小区内用户公共的标识对 HS-SCCH 进行加掩, 所述小区内用户公共的标识在系统广播消息发送, 具体地, 所述 标识可以为 H-RNTI、 E-RNTI等。在服务基站采用分组或者以整个小区为单 位进行 CELL_FACH DTX的激活 /去激活时, 可选地, 服务基站不需要获取 UE支持 CELL_FACH DTX的能力信息。
本发明实施例通过在非专用连接态下对 DPCCH进行非连续发送, 从而 能够降低对其他用户的上行干扰, 提高系统容量。 并且通过使得每套资源都 对应于一个资源 DTX偏置参数, 使得不同的用户的功率在时域上呈现均匀 分布, 进一步的降低了上行干扰, 增加用户数量, 从而进一步地提高了系统 谷里。
图 2是本发明一个实施例的非连续发送的方法的流程图。 图 2的方法由 网络侧执行。 应理解, 网络侧是相对于 UE而言的, 可以是 RNC, 也可以是 RNC与基站的合称, 还可以是 LTE中的 eNB, GSM中的 BSC等等, 本发 明对此不做限定。 针对本发明实施例, DTX的配置等主要是由 RNC来执行 的, DTX的配置是通过基站来下发给 UE的, 为了方便描述, 以下以 RNC 代指网络侧来进行说明。
201 , 网络侧确定非连续发送 DTX配置信息。
202, 网络侧向用户设备 UE发送 DTX配置信息, 以便于处于非专用连 接态的 UE根据 DTX配置信息向 UE的服务基站非连续发送专用物理控制信 道 DPCCH。
本发明实施例通过网络侧对 UE进行配置, 使得 UE在非专用连接态下 对 DPCCH进行非连续发送, 从而能够降低对其他用户的上行干扰, 提高系 统容量。
可选地, 作为一个实施例, 步骤 201 之前或者之后, 还可以包括接收 UE通过无线资源控制 RRC专用信令发送的 UE的非专用连接态的 DTX能 力信息; 或者接收 UE 通过 RRC 专用信令发送的 UE 的小区专用信道 CELL_DCH状态的 DTX能力信息, 以便于网络侧沿用 UE的 CELL_DCH 状态的 DTX能力信息作为 UE的非专用连接态的 DTX能力信息, 其中 UE 的非专用连接态的 DTX能力信息用于向网络侧指示 UE支持非专用连接态 的 DTX。
具体地, 用于上报 DTX 能力信息的 RRC 专用信令可以为 RRC connection setup complete、 Cell Update、 URA Update , RRC Connection Request 等信令。
进一步地,还可以沿用 UE在 CELL_DCH状态的 DTX能力信息作为非 专用连接态的 DTX的能力指示, 例如 CELL_FACH状态的 DTX能力信息, 即可以通过 UE支持小区专用信道 CELL_DCH状态的 DTX的信令向网络侧 上报 DTX能力信息, 也就是说: 只要支持非专用连接态的 DTX的 UE上报 了支持 DPCCH Discontinuous Transmission support (该 IE当前用于指示 UE 支持 CELL_DCH DTX的指示;),就代表该 UE同时支持非专用连接态的 DTX 和专用连接态的 DTX。
进一步地,通过 UE支持小区专用信道 CELL_DCH状态的 DTX的信令 向网络侧上报 DTX 能力信息还需要 UE 的版本信息, 如果 UE 支持 CELL_DCH状态的 DTX, 同时该 UE支持 common E-DCH, 则可以根据 UE 的版本信息判断该 UE是否支持 CELL_FACH状态的 DTX。 在这种情况下, UE支持 CELL_FACH状态的 DTX和 UE支持 CELL_DCH状态的 DTX的能 力上报可以采用同一个信元( Information Element, IE )。
可选地,作为一个实施例, 步骤 202可以包括: 通过系统广播发送 DTX 配置信息; 或者通过 RRC专用信令发送 DTX配置信息。 具体地, RNC可 以在 SIB中写入 DTX配置信息, 并通过系统广播的方式向 UE发送。 或者 可以通过列^口 Cell Update Confirm, Physical Channel Reconfiguration , Radio Bearer Reconfiguration, Radio Bearer Setup等 RRC专有信令携带 DTX配置 信息。 进一步地, 也可以由 RNC下发一个沿用指示, 或者通过协议约定, 使得 UE沿用 CELL_DCH状态的 DTX配置信息来作为 CELL_FACH状态的 DTX配置信息。
可选地, 作为一个实施例, 步骤 201 还可以包括: 通过系统广播或者 RRC专用信令向 UE发送用于指示 UE沿用小区专用信道 CELL_DCH状态 的全部或者部分 DTX配置信息的指令; 或者向 UE发送 CELL_DCH状态的 DTX配置信息, 以便于 UE根据与网络侧的预先约定, 沿用 CELL_DCH状 态的全部或者部分 DTX配置信息作为非专用连接态的 DTX配置信息。
其中, CELL_DCH状态的 DTX配置信息可以是在 UE由 CELL_DCH 状态转入非专用连接态之前接收到并存储在 UE本地的, 转入非专用连接态 后 UE可以直接沿用该 DTX配置信息。
可选地, 作为一个实施例, DTX配置信息可以包括: 第一 DTX周期; 第一 DTX周期中的 DPCCH发送长度; 用于指示不同的公共增强专用信道 common E-DCH资源配置所对应的 DTX偏置的资源 DTX偏置参数。上述配 置信息配置了具有一个周期的 DTX参数,其中 common E-DCH资源是在 SIB 中配置的, 一个小区目前最多可以配置 32套资源, 每套资源都对应于一个 资源 DTX偏置参数, 也就是说, 竟争到不同资源的 UE会错开非连续发送 的时间, 从而能够进一步的降低上行干扰, 使得不同的用户的功率在时域上 呈现均勾分布, 增加用户数量, 从而进一步地提高了系统容量。
可选地, 作为一个实施例, DTX 配置信息还可以包括以下参数: 第二 DTX周期; 第二 DTX周期中的 DPCCH发送长度; 启动第二 DTX周期的时 间。 用于配置第二个 DTX周期, 可以使得非连续传输到一定时间后变换发 送周期。如果第二周期为第一周期的整数倍, UE以第一 DTX周期发送一段 时间后, 使用更长的第二 DTX周期发送, 可以更进一步的降低上行干扰。
此外, DTX 配置信息还可以包含一些其他的参数, 例如媒体访问控制 MAC层 DTX的周期、 UE进入 MAC DTX的门限以及 UE在有数据需要发 送时提前发送 DPCCH的时间等。
可选地, 作为一个实施例, 该方法还包括: 通过帧协议向服务基站发送 UE的非专用连接态的 DTX能力信息,以便于服务基站激活 /去激活 UE的非 专用连接态的 DTX。 具体地, RNC 可以在高速下行共享信道数据帧类型 HS-DSCH DATA Frame Type 2或 3中携带 UE的 CELL_FACH DTX能力信 息, 通知给服务基站, 使得该服务基站可以根据 DTX能力信息针对支持非 专用连接态的 DTX的 UE下发激活 /去激活指示。
本发明实施例通过在非专用连接态下对 DPCCH进行非连续发送, 从而 能够降低对其他用户的上行干扰, 提高系统容量。 并且通过使得每套资源都 对应于一个资源 DTX偏置参数, 使得不同的用户的功率在时域上呈现均匀 分布, 进一步的降低了上行干扰, 增加用户数量, 从而进一步地提高了系统 谷里。
图 3是本发明一个实施例的非连续发送的方法的交互图。
301 , UE向 RNC上报 DTX能力信息。
首先, UE需要向网络侧上报自己是否支持 CELL_FACH状态的 DTX的 能力信息。 本发明实施例主要涉及 UE支持 CELL_FACH状态的 DTX的情 况, 具体地, UE可以通过以下几种方式上报 DTX能力信息。 第一种, UE可以通过包含有 DTX能力信息的 RRC专用信令来向 RNC 上才艮,例: ¾口,该专用信令可以为 RRC connection setup complete, Cell Update, URA Update, RRC Connection Request等。 更进一步地, DTX能力信息可以 包含在物理信道能力 ( Physical Channel Capability )信元 IE当中。 例如, 该 IE 具体可以为: 小区前向接入专用物理控制信道非连续发送支持 ( CELL—FACH DPCCH DTX Support, 或者 Support of CELL—FACH DTX 等)。 具体的 IE格式可以为:
Figure imgf000017_0001
第二种, UE支持 CELL_FACH状态的 DTX和 UE支持 CELL_DCH状 态的 DTX能力采用同一个 IE, 即通过 UE支持 CELL_DCH状态的 DTX的 信令向网络侧上报 CELL_FACH DTX 能力信息。 具体地, UE 上报支持 CELL_DCH状态的 DTX的能力, 同时认为如果 UE支持 CELL_DCH状态 的 DTX则 UE也可能会支持 CELL_FACH状态的 DTX, 则无须再引入 UE 的能力上报。 目前 UE上报支持 CELL_DCH状态 DTX的方式为:
Figure imgf000017_0002
以上方法需要 UE版本信息的支持, 如果 UE支持 CELL_DCH状态的 DTX 同时 UE 支持 common E-DCH , 并且获得 UE 的版本属于引入 CELL_FACH DTX 时以及之后的版本, 则网络侧判断该 UE 也支持 CELL_FACH状态的 DTX。 例如: 只有 Rell2 版本之后的 UE 才会支持 CELL_FACH DTX, 也就是说如果网络侧接收到 UE支持 CELL_DCH状态 的 DTX且 UE支持 common E-DCH,同时网络侧获得 UE的版本信息为 Rell2 以及之后,则网络侧判断该 UE同时支持 CELL_FACH状态的 DTX。具体地, 上述 UE的版本是指 UE实现该特性的版本, 对应到协议中即该特性引入标 准之后所对应的协议版本, 目前 UE会向网络侧上报所述的版本信息,例如: Relll , Rell2等; 对应到实现中是指真正应用该特性的 UE。 应理解, 通常来说, UE会优选地在接入网络, 状态切换, 小区切换 /重 选等需要系统信息更新的时候上报 DTX能力信息。 但步骤 301的执行顺序 并不因此而受到限制, UE可以灵活的在任何时候上报 DTX能力信息, 也可 以由网络侧下发 DTX 能力信息上报指示, UE在接收到该上报指示时上报 DTX能力信息。 并且, UE向网络侧上报 DTX能力信息的过程需要经由 UE 的服务基站转发。
此外, UE的服务基站也可以向 RNC上报支持 CELL_FACH状态的 DTX 能力信息。 具体地,服务基站可以通过将 DTX能力信息包含在审计(Audit ) 响应或者资源状态指示( Resource Status Indication )信令中向 RNC上报能力 信息。 该服务基站的 DTX能力信息反映了该基站下的小区, 或者该基站是 否支持 CELL_FACH状态的 DTX。 与 UE上报 DTX能力信息相类似, 服务 基站的上报时机也可以很灵活。
302, DTX配置信息
DTX配置信息具体的参数可以包括第一 DTX周期、 第一 DTX周期中 的 DPCCH长度以及资源 DTX偏置。 其中资源 DTX偏置是针对不同的资源 配置而设置的。 例如:
UE DTX cycle 1 ( UE的第一 DTX周期 )
UE DPCCH burstl ( UE的第一 DTX周期中传输 DPCCH的长度) Resource DTX offset (资源 DTX偏置)
以上 3项配置了最基本的 DTX发送周期图样,其中 Resource DTX offset 需要根据不同的资源进行配置,具体来说, CELL_FACH状态使用的 common E-DCH资源是在 SIB中配置的, 一个小区目前可以配置最多 32套资源, 在 UE需要发送上行数据时, 需要竟争资源, 如果针对不同的资源优选地配置 不同的 Resource DTX offset, 则不同的 UE竟争到不同的资源时对应的 DTX 偏置也不相同, 也就是说竟争到不同资源的 UE会因为不同的偏置而错开非 连续发射的时间, 从而能够进一步的降低上行干扰, 使得不同的用户的功率 在时域上呈现均勾分布, 增加用户数量, 从而进一步地提高了系统容量。
可选地, DTX配置信息还可以包括其他一些参数来进一步增强 DTX的 功能以及可靠性等, 例如, 网络侧还可以配置以下参数:
UE DTX long preamble length (提前发送 DPCCH的时间)在 UE有上 行数据需要发送时, UE在 E-DPCCH需要传输的前几个时隙 slot就需要开 始发送 DPCCH来进行功率调整,该参数就是用来设定这一提前发送时间的, 其单位可以是时间, 也可以是时隙的个数等, 本发明对此不做限定。
MAC DTX cycle (用于 MAC层的非连续发送的周期) RNC可以通过 配置 MAC DTX cycle来限制 UE E-DCH的发送, 实现上行 DPCCH断续发 送。
MAC Inactivity Threshold ( UE进入 MAC DTX的门限)
CQI DTX Timer ( CQI比 DTX的优先级高, 可以连续发送的时间) 当网络侧配置两个 DTX周期时, DTX配置信息还可以包含以下参数: UE DTX cycle 2 ( UE的第二 DTX周期 )
UE DPCCH burst_2 ( UE的第二 DTX周期中的数据传输长度)
Default SG in DTX Cycle 2 (上行数据发送时所使用的授权 )
Inactivity Threshold for UE DTX cycle 2 (UE进入 cycle2的时间 ) 第二 DTX周期参数的配置可以使得 UE在以第一 DTX周期发送 DPCCH 一段时间后转入使用第二 DTX周期进行发送, 这样可以通过设置更长的第 二 DTX周期来阶梯性地进一步降低上行干扰。
303 , RNC向 UE下发 DTX配置信息。
RNC在接收到步骤 301 中 UE上报的 DTX能力信息后, 或者是 RNC 按照预先设定的周期向 UE下发 DTX配置信息。 具体地, RNC可以通过系 统广播, 或者 RRC专用信令来向 UE下发 DTX配置信息。
RNC可以将上述步骤 302中的参数写入系统信息 SIB当中, 系统广播
SIB来下发 DTX配置信息, 优选地, RNC可以在 SIB5中下发该配置信息。
RNC通过 RRC专有信令下发 CELL_FACH DTX参数( DTX配置信息), 该专用信令可能是 Cell Update confirm(小区更新确认)/ PHYSICAL CHANNEL RECONFIGURATION (物理信道重配置) / RADIO BEARER RECONFIGURATION (无线承载重配置) / RADIO BEARER RELEASE (无线 承载释放) / RADIO BEARER setup (无线承载建立)/ RRC connection Setup ( RRC连接建立 Vtransport channel reconfiguration传输信道重配置)等 RRC 消息。
此外, 还可以由网络侧下发一个沿用指示, 或者通过约定, 使得 UE沿 用已有的 CELL_DCH 状态的部分或者全部 DTX 配置信息来作为 CELL_FACH状态的 DTX配置信息。 应理解, 网络侧下发 DTX配置信息给 UE的过程需要经由服务基站转 发。
此外, 网络侧还需要将 DTX配置信息下发给服务基站, 具体地, RNC 可以在 Physical Shared Channel Reconfiguration Request (物理共享信道重酉己 置请求) 消息中将 DTX配置信息下发给基站。 进一步地, 网络侧还可以指 示 NodeB沿用用户设备在专用连接态配置的 DTX信息, 该指示信息可以采 用约定的方式, 也可以通过 RNC下发沿用指示的方式。
304, UE计算 DPCCH发送 pattern。
可选地,在 UE有上行数据需要发送时, UE在 E-DPCCH需要传输的前 几个 slot开始发送 DPCCH来进行功率调整, 提前的时间由上述步骤 302中 UE DTX long preamble length进行配置, 或者可以约定提前发送的时间, 例 如提前 2个 slot开始发送 DPCCH。 通常在上行数据发送完成之后, UE会继 续发送一个 slot的 DPCCH, 来再次进行功率调整。
在定时器运行的这段时间 UE没有上行数据发送 ,但是控制信道 DPCCH 仍然会继续发送, 为了降低 DPCCH对其他用户的干扰, 此时采用非连续发 送的方式, UE在没有数据传输时采用以下公式计算需要发送 DPCCH的一 系列时间点 (即 DPCCH发送的图样 pattern ):
((5*CFN -DTX—Offset + S) MOD DTX_cycle) = 0
其中, CFN为连接帧号 ( Connection Frame Number ), S为一个连接帧 中的子帧号。其中 DTX_cycle和 DTX_offset可以为上述实施例中 DTX配置 信息中的参数第一 DTX周期和资源 DTX偏置, MOD为取模运算。 通过上 述公式可以计算出一系列的发送时间点, 从而组成 DPCCH的发送 pattern。 更进一步地, UE还可以采用两个周期来计算 DPCCH的发送 pattern, 仍旧 采用上述公式, 其中 DTX_cycle为上述实施例中 DTX配置信息中的参数第 二 DTX周期。 在 UE没有数据传输时 UE先采用第一 DTX周期( UE DTX cyclel )计算 DPCCH发送的 pattern,在一段时间之后( Inactivity Threshold for UE DTX_cycle2 )UE开始采用第二 DTX周期( UE DTX cycle 2 )计算 DPCCH 发送的 pattern。 其中 UE计算 DPCCH发送的时间点所用的公式和上述第一 DTX 周期计算公式相类似, 不同之处在于公式对应的参数不同, 网络侧针 对 UE的不同周期和不同资源配置不同的 Resource DTX_Offset等参数, 尽 可能使得不同的 UE的功率在时域上呈现均匀分布, 以达到降低上行干扰的 目的。
305 , UE非连续发送 DPCCH。
当 UE有上行数据传输时, UE竟争 common E-DCH资源, 并采用该资 源发送上行的数据。 如果网络侧配置 UE采用隐式资源释放的方式, 在数据 传输完成之后, 则 UE会启动隐式资源释放定时器, 在隐式资源释放定时器 运行期间如果 UE有上行的数据发送, UE会停止该定时器, 等待数据发送 完成之后则重新启动。 如果在隐式资源释放定时器运行期间 UE接收到下行 的数据, UE会重启该定时器。
在 UE进入 DTX状态之后, 如果 UE有上行数据需要发送时, UE在 E-DPCCH需要传输的前几个 slot开始发送 DPCCH来进行功率调整, 提前 的时间根据接收到的 DTX配置信息中的 UE DTX long preamble length确定, 或者可以约定提前发送的时间, 例如提前 2个 slot开始发送 DPCCH。 通常 在上行数据发送完成之后, UE会继续发送一个 slot的 DPCCH, 来再次进行 功率调整。 之后 UE没有数据需要传输时, 按照上述步骤 304中计算得到的 DPCCH发送 pattern中的一系列发送时间点来发送 DPCCH的功率控制、 导 频等控制信号。 资源释放定时器计时结束后, 释放该竟争到的资源以供其他 用户使用。
进一步地,在网络侧配置采用隐式资源释放定时器进行资源释放时, UE 在隐式资源释放定时器启动时即开始计算 DPCCH发送的图样, 开始断续的 发送 DPCCH。
进一步地,在网络侧配置采用显式资源释放的方式进行资源释放时, UE 在没有数据发送时即开始计算 DPCCH 发送的图样, 开始断续的发送 DPCCH。
306, DTX激活 /去激活。
支持 CELL_FACH状态的 DTX的 UE在竟争得到 common E-DCH资源 时或者在接收到 CELL_FACH的 DTX配置信息时,则认为 CELL_FACH DTX 被激活, 然而实际应用中可能需要对 UE的 DTX功能的开启和关闭进行灵 活的控制, 这里可以由 UE的服务基站通过 HS-SCCH order对 UE的 DTX 激活 /去激活。 因为基站需要针对支持 DTX能力的 UE实施激活 /去激活, 步 骤 306的相对执行顺序为: 在上述步骤 301基站获得 DTX能力信息之后执 行, 与步骤 301相类似地, 本发明不限定其绝对执行顺序。 需要说明的是, 本发明实施例所对应的非专用连接态的 DTX配置流程 同样也适用于非专用连接态的非连续接收 DRX特性。
本发明实施例通过在非专用连接态下对 DPCCH进行非连续发送, 从而 能够降低对其他用户的上行干扰, 提高系统容量。 并且通过使得每套资源都 对应于一个资源 DTX偏置参数, 使得不同的用户的功率在时域上呈现均匀 分布, 进一步的降低了上行干扰, 增加用户数量, 从而进一步地提高了系统 谷里。
