Description

一种信号传输方法及设备
技术领域
本发明涉及无线通信技术领域， 尤其涉及一种信号传输方法及设备。 背景技术
随着移动通信技术的发展， 用户对网络带宽的需求越来越高， 为了提升 网络数据传输效率， 可以在宏小区 （macro cell ) 中引入低功率站点 （LPN, Low Power Node)构成低功率小区，如微小区（ micro cell )、微微小区( pico cell )、 毫微微小区 （femto cell )等， 使这些低功率小区覆盖到业务热点区域或无小 区覆盖的区域， 这样， 当用户终端（ User Equipment , UE )移动到这些区域时， 可以将 UE的业务切换到这些低功率小区， 以实现业务分流或弥补覆盖。
UE切换进入新的小区的具体过程一般为： UE接收所在源小区的通信节 点 （即源通信节点） 的测量配置信息， 其中包括测量的频率信息； 根据接收 的频率信息， UE探测该频率信息对应的目标小区的参考信号， 并对探测到参 考信号的目标小区进行测量； UE将测量结果上报给源通信节点， 源通信节点 根据测量结果确定进行小区切换后， 向探测到的目标小区的通信节点 （即目 标通信节点）发起切换请求； 目标通信节点根据目标小区的网络条件， 比如 负载、 干扰、 传输网络带宽等， 决定是否接纳该 UE的业务， 如果不能接纳， 目标通信节点向源通信节点发送拒绝切换或切换失败的信息， 如果能接纳， 目标通信节点向源通信节点发送同意切换或确认切换的信息。 如图 1 所示， 为在异构网络下， UE在不同小区之间进行切换的示意图。
现有技术中， 目标小区在提供服务时， 目标小区的目标通信节点会持续 发送参考信号， 在目标小区关闭服务时， 目标小区的发射机会关闭， 目标通 信节点也就不再发送参考信号。 由于在目标小区提供服务时， 该目标小区的 参考信号是被持续发送的， 即使在目标小区的负载很重时， 该参考信号覆盖 范围内的 UE也可以探测到该目标小区， UE在对目标小区测量完成后将测量 结果上 ·^艮给源通信节点，源通信节点分析 UE的测量结果并确定进行小区切换 后， 向目标通信节点发送切换请求， 但是， 目标通信节点在接收到该切换请 求时， 可能会因为目标小区负载过重而拒绝该切换请求， 这样， UE之前的测 量上报过程、 源通信节点接收并分析测量结果的过程以及源通信节点与目标 通信节点之间的交互过程便成为无效的工作， 尤其当目标小区部署在热点区 域时， 由于 UE的数量比较多， 会带来很大的无效工作量。 如图 2所示， 为目 标小区因负载过重拒绝 UE接入的示意图。
上述无效工作增加了 UE 与源通信节点之间以及源通信节点与目标通信 节点之间不必要的信令开销， 增加了源通信节点分析测量结果的运行负担， 并且， 由于 UE在测量过程中不能被源小区调度， 无法进行正常的信息传输， 以上无效的测量过程会严重影响 UE的吞吐量。
另外， 在相关技术中， 参考信号一旦开始发送， 其发送状态不再改变。 发明内容

如图 15所示， 为本发明实施例一提供的进行信号传输的方法流程图， 包 括：
S151 : 第一通信节点调整属于该第一通信节点的小区的参考信号的发送 状态；
S152: 第一通信节点根据调整后的参考信号的发送状态， 发送所述小区 的参考信号。
这里，调整的参考信号是指可以使其它小区的 UE或基站等发现该第一通 信节点的小区 （以下称为目标小区） 的参考信号， 参考信号中可以包含小区 标识（Identity, ID ); 第一通信节点可以是基站、 基站处理器、 用户设备 (User Equipment, UE)等任何可以形成或管理一定的信号覆盖区域的设备； 具体地， 第一通信节点可以是 LTE系统中管理目标小区的基站， 相应地， 其它设备具 体可以是目标小区外的用户设备 (User Equipment, UE)和 /或基站等； 第一通信 节点还可以是 WCDMA系统中的 RNC ,相应地， 其它设备具体可以是目标小 区外的 UE、 Node B、 或 RNC等； 第一通信节点还可以是 Device-to-Device ( D2D )通信中的 UE, 目标小区可以是 UE形成的信号覆盖区域， 其它设备 具体可以是目标小区外的 UE、 基站、 或基站处理器等。
在具体实施中， 第一通信节点在确定需要调整参考信号的发送状态， 以 阻止其它设备探测到或测量或接入该目标小区， 或减少其它设备探测到或测 量或接入该目标小区的概率时， 调整目标小区的参考信号的发送状态； 具体 地， 第一通信节点可以在确定管理的目标小区过载时， 调整参考信号的发送 状态。
本发明实施例既可以应用于在小区切换时， 第一通信节点主动选择是否 允许其它 UE接入目标小区， 也可以应用于协同多点 (Coordinated multiple point, CoMP)传输时，第一通信节点主动选择是否参与其它通信节点的 CoMP 传输，也可以应用于基站之间协助传输回程网络数据，还可以应用于 UE之间 进行设备对设备 ( Device-to-Device, D2D )通信等。
本发明实施例在应用于小区切换时， UE在对目标小区进行探测或测量或 接入目标小区之前， 可以根据目标小区当前的参考信号的发送状态， 获知目 标小区是否会接纳该 UE, 从而可以避免因目标小区拒绝接纳该 UE而产生的 不必要的工作量； 本发明实施例在应用于 CoMP传输时， 基站在请求其它基 站协同传输之前，就可以获知其它基站当前是否具备进行 CoMP传输的能力， 从而可以避免基站与其它基站之间不必要的信令交互。
如图 16所示，为本发明实施例基站之间协助传输回程网络数据的示意图； 当基站 1的回程网络资源匮乏或不可用时， 基站 1可以通过与基站 2之间的 空口连接到核心网； 具体地，基站 1将上行（ Uplink, UL )数据传输给基站 2, 由基站 2通过自身的回程网络资源将接收的基站 1的数据传输给核心网； 或 者， 核心网将下行（Downlink, DL )数据传输给基站 2, 基站 2通过基站 1 和基站 2之间的空口将接收的数据传输给基站 1 ;这种传输方法应用的前提是 基站 2可以提供这种协助传输回程网络数据的能力，比如基站 2在超负载（ over load ) 时， 可能无法提供这种能力， 在低负载（low load ) 时， 可以提供这种 能力； 本发明实施例中， 基站 1 在确定采用这种传输方式传输数据之前， 可 以根据基站 2发送的参考信号的发送状态， 获知基站 2当前是否可以提供这 种协助传输回程网络数据的能力， 从而可以避免出现基站 1在向基站 2发送 承载请求， 即请求基站 2协助传输回程网络数据时， 基站 2由于不能提供这 种协助传输回程网络数据的能力而拒绝基站 1 的请求的情况， 因此， 采用本 发明实施例， 可以减少基站之间不必要的信令交互。
当本发明实施例应用于 D2D通信时， UE在确定采用 D2D通信方式与其 它通信设备之间传输数据之前， 可以根据其它通信设备发送的参考信号的发 送状态， 获知其它通信设备当前是否具备与该 UE进行 D2D通信的能力， 从 而可以避免因该 UE在向其它通信设备发送 D2D通信请求时被拒绝而产生的 不必要的信令交互。 较佳地， 步骤 S151中， 第一通信节点调整属于该第一通信节点的小区的 参考信号的发送状态， 包括： 第一通信节点调整所述参考信号的发送状态为 停止发送所述小区的参考信号； 第一通信节点根据调整后的所述参考信号的 发送状态， 发送所述小区的参考信号包括： 第一通信节点停止发送所述小区 的参考信号； 或
第一通信节点调整属于第一通信节点的小区的参考信号的发送状态， 包 括： 第一通信节点降低发送所述小区的参考信号的发送功率； 第一通信节点 根据调整后的所述参考信号的发送状态， 发送所述小区的参考信号包括： 第 一通信节点使用所述降低的发送功率发送所述参考信号； 或

在具体实施过程中， 若第一通信节点确定需要阻止其它设备， 如其它小 区的 UE等探测到或测量或接入目标小区， 则可以停止发送参考信号； 若第一 通信节点确定只需要减少其它设备探测到或测量或接入该目标小区的概率， 可以不停止发送参考信号， 只是采用降低发送功率、 延长发送周期、 降低占 用带宽等方式， 增加其它设备探测到该目标小区的难度； 具体地， 通过降低 发送参考信号的发送功率， 可以降低参考信号的覆盖范围， 减少探测到或测 量或接入该目标小区的设备； 通过延长发送参考信号的发送周期， 可以使其 它设备探测到或测量或接入该目标小区的概率降低； 通过降低占用的带宽发 送参考信号， 同样可以降低参考信号的覆盖范围， 降低占用的带宽具体有两 种形式， 一种是降低总带宽， 比如从之前占用 20M带宽发送参考信号调整至 只占用 10M带宽发送参考信号，或者，从之前占用 110个物理资源块（Physical Resource Block, PRB )发送参考信号调整至只占用中间的 6个 PRB发送参考 信号； 另一种是保持总带宽不变， 但减小总带宽中包含的频率资源的密度， 比如可以将频率密度调整为之前的一半。

在具体实施过程中， 第一通信节点可以在确定目标小区过载时， 调整参 考信号的发送状态； 目标小区过载有多种体现， 具体可以是， 无线资源过载、 TNL网络过载、硬件资源过载等；其中，无线资源一般以物理资源块（Physical Resource Block, PRB )作为最小调度单位， 在具体实施中， 第一通信节点可 以在无线资源占用率超过设定阈值时， 确定无线资源过载， 比如， 第一通信 节点在当前 PRB占用率超过 70%时， 确定无线资源过载， 无线资源过载具体 可以由目标小区的调度器判定； TNL 网络过载是指若第一通信节点在向其它 通信节点， 如路由设备等发送数据时， 接收到其它通信节点反馈的链路拥塞 指示， 则确定当前回程链路网络过载； 硬件资源过载， 比如， 当前中央处理 器（ Central Processing Unit, CPU )使用率超过设定阈值， 内存占用率超过设 定阈值等。
本发明实施例中， 目标小区在调整参考信号的发送状态后， 继续和已经 接入的 UE、 基站等通信设备通信， 也即， 在调整参考信号的发送状态后， 目 标小区继续保持控制信道和数据信道的发射状态。

指示所述小区内的通信设备不再测量所述参考信号；
指示所述小区内的通信设备测量设定类型的参考信号， 所述设定类型与 调整的参考信号类型不同。
这里的通信设备可以是 UE、 基站等无线通信设备， 在具体实施过程中， 第一通信节点可以通过停止发送参考信号来或测量其它设备探测到目标小 区， 或通过降低发送功率、 延长发送周期、 降低占用带宽等方式来降低其它 设备探测到或测量或接入目标小区的概率； 第一通信节点在调整参考信号的 发送状态后， 可以向目标小区内的通信设备发送指示信息， 也即， 第一通信 节点在调整参考信号的发送状态后， 确定如何使目标小区内的通信设备继续 进行 RRM测量、 信道状态信息 ( Channel State Information , CSI )测量、 无 线链路管理（Radio Link Management, RLM )测量等， 在具体实施中， 该指 示信息指示的方式可以是显式指示， 也可以是隐式指示， 也即， 第一通信节 点可以将需要通信设备执行的任务明确表示在指示信息中， 也可以将需要通 信设备执行的任务体现在与具体指示任务相关的其它信息中， 通信设备可以 根据与网络侧的约定， 从与具体指示任务相关的其它信息中确定出该指示信 息。
具体地， 该指示信息可以包含调整后的参考信号的发送状态， 通信设备 可以根据该指示信息指示的调整后的参考信号的发送状态， 判断是否测量调 整发送状态后的参考信号， 比如， 若调整后的参考信号的发送状态为停止发 送参考信号， 则通信设备确定不再测量调整发送状态后的参考信号， 若调整 后的参考信号的发送状态包括不停止发送， 则通信设备确定测量调整发送状 态后的参考信号， 其中， 该指示信息可以明确指示通信设备判断是否测量调 整后的参考信号的发送状态， 也可以由通信设备根据与网络侧的约定， 在接 收到调整发送状态后的参考信号后， 即自行判断是否测量调整发送状态后的 参考信号； 该指示信息还可以包含调整后的测量配置信息， 通信设备根据该 测量配置信息测量调整发送状态后的参考信号， 调整后的测量配置信息相比 调整前的测量配置信息可以是延长测量周期后的测量配置信息和 /或降低测量 占用带宽后的测量配置信息等， 具体地， 该指示信息可以明确指示通信设备 根据该测量配置信息测量调整发送状态后的参考信号， 也可以由通信设备根 据与网络侧的约定， 在接收到该测量配置信息后， 即自行根据该测量配置信 息测量调整发送状态后的参考信号； 该指示信息还可以指示通信设备不再测 量调整发送状态后的参考信号， 这时， 通信设备在根据该指示信息不再测量 调整发送状态后的参考信号后， 可以选择其它参考信号进行测量， 这里的其 它参考信号可以是通信设备与网络侧预先约定的， 也可以是由通信设备自己 决定的； 该指示信息还可以指示通信设备测量设定类型的参考信号， 比如， 若调整后的参考信号的发送状态为停止发送， 第一通信节点还可以指示目标 小区的通信设备采用其它的参考信号进行 RRM测量、 CSI测量、 RLM测量 等。

在具体实施过程中， 第一通信节点在停止发送需要调整的参考信号后， 这些参考信号在被停止发送之前占用的资源被用来进行第一通信节点与目标 小区内的所有通信设备或设定通信设备之间传输数据和 /或控制信令； 若第一 通信节点不停止发送需要调整的参考信号， 只是延长发送周期或降低占用带 宽等发送参考信号， 则第一通信节点可以通知目标小区内的通信设备在之前 承载参考信号的部分资源上接收数据和 /或控制信令， 这里的通信设备可以是 UE、 基站等无线通信设备， 具体地， 第一通信节点可以显式通知， 也可以隐 式通知目标小区内的通信设备在之前承载参考信号的部分资源上接收数据和 / 或控制信令， 比如， 若第一通信节点将参考信号发送周期从 100ms 调整为 300ms,则调整发送周期后空闲的 200ms可以被用来向目标小区内的通信设备 发送数据和 /或控制信令， 第一通信节点可以明确通知目标小区内的通信设备 在空闲的 200ms接收数据和 /或控制信令， 也可以由通信设备根据与网络侧的 约定， 根据第一通信节点调整后的参考信号的发送周期， 确定需要在空闲出 的时间内接收数据和 /或控制信令； 再比如， 若第一通信节点将发送参考信号 占用的 20M带宽调整为只占用中间的 1.4M带宽， 则调整发送参考信号占用 的带宽后， 第一通信节点可以显式或隐式通知目标小区内的通信设备空闲出 的带宽被用来向目标小区内的通信设备发送数据和 /或控制信令； 也即， 第一 通信节点在调整参考信号发送状态后， 可以为通信设备配置之前承载参考信 号的资源中被用来传输数据和 /或控制信令的时隙和 /或频率资源。

在具体实施过程中， 这里的第一通信节点和通信节点具体可以是基站或 基站处理器， 第一通信节点在调整目标小区的参考信号的发送状态后， 还可 以将调整后的参考信号的发送状态发送给相邻小区的通信节点， 以使该相邻 小区的通信节点根据该调整后的参考信号的发送状态判断是否需要该相邻小 区内的 UE测量目标小区， 比如， 若第一通信节点调整后的参考信号的发送状 态为停止发送参考信号， 则该相邻小区的通信节点确定不需要对目标小区进 行测量， 若第一通信节点调整后的参考信号的发送状态为降低发送功率发送 和 /或延长发送周期发送和 /或降低占用的带宽发送等， 则该相邻小区的通信节 点可以确定仍需要 UE对目标小区进行测量， 只是需要调整测量配置信息； 其 中， 若第一通信节点延长发送周期发送参考信号， 则相邻小区的通信节点根 据该参考信号的发送状态调整本小区内 UE的测量周期，使 UE降低测量目标 小区的周期， 比如第一通信节点调整参考信号的发送状态， 从每 5个子帧发 送一次调整到每 10个子帧发送一次， 那么， 相邻小区的通信节点调整本小区 内的 UE测量目标小区的测量周期，使本小区内的 UE从每 5个子帧测量一次 目标小区调整到每 10个子帧测量一次目标小区； 相应地， 若第一通信节点降 低占用的带宽发送参考信号，则相邻小区的通信节点降低本小区内的 UE测量 目标小区时占用的带宽； 若第一通信节点降低发送功率发送参考信号， 则相 邻小区的通信节点在确定信号传输路损时， 采用调整后的发送功率作为目标 小区的发射功率， 并与实际接收的功率相比较， 确定路损， 以便于确定目标 小区与该相邻小区在地理位置上的关系。
较佳地， 第一通信节点调整属于该第一通信节点的小区的参考信号的发 送状态后， 还包括：
第一通信节点在确定需要发送参考信号后， 发送包括所述小区负载信息 的参考信号。
这里， 探测到所述参考信号的通信设备具体可以是基站、 UE等， 采用本 发明实施例， 通信设备不需要读取 RRC层的系统广播消息， 也不需要读取其 它额外的物理信道信息， 在探测目标小区的同时就能获取到目标小区的负载 信息， 这种获得负载信息的方式效率较高， 且通信设备根据该负载信息可以 判断是否对目标小区进行测量， 或判断是否将测量目标小区的测量结果上报， 或判断是否接入目标小区， 比如， 该负载信息指示目标小区超负载， 则通信 设备可确定不对目标小区进行测量， 或不将测量结果上报， 或不接入目标小 区； 该负载信息指示目标小区负载轻， 则通信设备可确定对目标小区进行测 量， 或将测量结果上报， 或接入目标小区。 通信设备可以根据参考信号的配 置， 实现对参考信号快速检测的同时获取目标小区的负载， 从而避免长期间 读取系统广播消息导致通信设备不能被服务小区调度导致的吞吐量下降。

在具体实施过程中， 可以采用多种方式将负载信息加入到参考信号中， 比如第一通信节点采用与负载信息对应的参考信号发送周期发送参考信号， 通信设备根据与网络侧的约定， 可以根据该参考信号发送周期确定目标小区 的负载信息， 比如， 可以将小区负载情况分为三种， 按照负载由低到高分别 为低负载 （low load )、 高负载（high load )和超负载（over load ), 对于低负 载的小区， 参考信号发送周期设定为 100ms , 对于高负载的小区， 参考信号 发送周期设定为 200ms , 对于超负载的小区， 参考信号的发送周期设定为 300ms; 相应地， 第一通信节点占用与负载信息对应的带宽发送参考信号， 通 信设备根据该参考信号占用的带宽确定目标小区的负载情况； 还可以在参考 信号中加入与负载信息对应的编码信息， 比如采用在参考信号中增加一个比 特位代表负载信息， 具体地， 可以用 0比特代表小区负载正常， 用 1 比特代 表小区超负载。
较佳地， 步骤 S151中， 第一通信节点调整属于所述第一通信节点的小区 的参考信号的发送状态， 包括： 所述第一通信节点通过所述第一通信节点管理的通信设备， 调整所述小 区的参考信号的发送状态； 或

( Radio Resource Control, RRC )层指示的调整方式， 调整所述参考信号的发 送状态。
在具体实施过程中， 该第一通信节点在发送参考信号的过程中， 可以通 过该第一通信节点的无线资源管理 ( Radio Resource Management, RRM )功 能确定需要调整参考信号的发送状态， 之后可以自行调整参考信号的发送状 态， 也可以指示管理的目标小区内的其它通信节点调整参考信号的发送状态； 具体地， 该第一通信节点可以为基站， 目标小区为该基站发射信号形成的信 号覆盖区域， 这时， 基站可以自行调整参考信号的发送状态； 当第一通信节 点指示管理的其它通信节点调整参考信号的发送状态时， 该第一通信节点可 以是基站， 而管理的其它通信节点可以是远端无线端口 （Remote Radio Head, RRH )等；
在具体实施过程中， 第一通信节点的 RRC层可以确定调整参考信号的发 送状态的具体调整方式， 如停止发送参考信号、 降低发送功率发送参考信号、 降低占用带宽发送参考信号、 延长发送周期发送参考信号等， 并将确定的调 整方式传输至物理层， 指示物理层根据该调整方式调整参考信号的发送状态。
较佳地， 步骤 S151之后， 还包括：
第一通信节点在确定需要恢复所述参考信号的发送状态后， 恢复所述参 考信号的发送状态， 并使用恢复后的发送状态发送所述参考信号。
在具体实施过程中， 当目标小区的负载正常后， 第一通信节点可以恢复 参考信号的发送状态， 比如， 若之前停止了发送参考信号， 则恢复发送参考 信号； 若之前降低了发送参考信号的发送功率， 则恢复之前的发送功率发送 参考信号， 若之前延长了发送参考信号的发送周期， 则恢复之前的发送周期 发送参考信号， 若之前降低了发送参考信号占用的带宽， 则恢复之前占用的 带宽发送参考信号。 在具体实施过程中， 与恢复参考信号的发送状态相关的操作是与之前调 整参考信号的发送状态相对应的， 比如：
