Description

传输调度请求的方法和装置、 用户设备以及基站 技术领域
本发明涉及通信技术领域,具体而言,涉及传输调度请求的方法和装置、 用户设备以及基站。 背景技术
高级长期演进( LTE-A, Long Term Evolution-Advanced )是第三代合作 伙伴计划 ( 3GPP, 3rd Generation Partnership Project )长期演进( LTE, Long Term Evolution ) 系统的进一步演进和增强系统。 在 LTE-A系统中, 为了满 足国际电信联盟对于第四代通信技术的峰值数据速率要求引入了载波聚合 ( CA, Carrier Aggregation )技术, 也称频谱聚合 ( Spectrum Aggregation ) 技术或者带宽扩展 ( Bandwidth Extension )技术。 载波聚合中, 两个或更多 的成员载波( Component Carrier ) 的频语被聚合在一起以得到更宽的传输带 宽, 各成员载波的频谱可以是相邻的连续频谱、 也可以是同一频带内的不相 邻频谱甚至是不同频带内的不连续频语。 LTE-A 用户设备 (UE , User Equipment )根据其能力和业务需求可以同时接入多个成员载波进行数据收 发。
现有载波聚合系统都是同一个基站( eNB , Evolved NodeB )下的载波进 行聚合, 或者有理想回传(Backhaul )的宏 (Macro ) 小区和微(Pico ) 小区 下的载波聚合, 比如宏小区和微小区通过光纤连接(此时微小区也可以是无 线射频头), 这样多个载波间可以采用联合调度, 即 eNB在调度聚合载波中 的一个载波时, 也知道另一个载波上的调度情况。
在后续演进的 LTE系统中,会引入基站间的载波聚合, 此时基站间是非 理想回传, 因此基站间无法实时传送数据。 如图 1所示的宏微小区耦合的场 景下, 部署在频率 fl 的宏小区主要提供系统信息, 无线链路监测和移动性 管理, 以保证业务的连续性; 同时为了保证语音业务服务的连续性, 对半持 续调度业务通常也由宏小区服务。 部署在频率 f2 的在宏小区的覆盖范围内 的多个微小区主要提供高数据速率业务的传输, 上述宏小区和微小区, 还有 微小区之间都是非理解回传。
调度请求( SR, Scheduling Request )信息用于 UE向基站请求发送上行 数据的资源。现有 CA系统中, SR信息只发送在上行主载波上。在上述 eNB 间的 CA 系统中, 若 SR信息的传输仍采用现有机制, 则当宏小区收到 SR 信息而获知 UE需要传输上行数据时, 需要再通过 X2接口通知 Pico为 UE 进行上行数据的调度。 由于基站间无法实时传送数据, 则会延迟上行数据得 到服务的时间, 从而降低用户的感受。 发明内容

为了更清楚地说明本发明实施例的技术方案, 下面将对本发明实施例中 所需要使用的附图作筒单地介绍, 显而易见地, 下面所描述的附图仅仅是本 发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的 前提下, 还可以根据这些附图获得其他的附图。

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: 全球移动通讯系 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 ), LTE等。
UE也可称之为移动终端 (Mobile Terminal ), 移动台 ( Mobile Station ) 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。 用户设备与无线接入网交换语音和 /或数据。
基站,可以是 GSM或 CDMA中的基站( BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站( Node B ),还可以是 LTE中的演进型基站( eNB 或 e-NodeB, evolutional Node B ), 本发明并不限定, 但为描述方便, 下述实 施例以 Node B为例进行说明。 另外, 一个基站可能支持 /管理一个或多个小 区 (cell ), UE需要和网络通信时, 它将选择一个小区发起网络接入。
在 MSA场景中, 宏小区和微小区均具有接收 SA信息的能力。 当 UE 发送 SA信息后,载波聚合系统中的基站只要识别出发送给自己的 SA信息, 那么 SA信息就不需要通过宏基站转发, 由此可以同时避免延迟上行数据得 到服务的时间, 提高用户感受。
以下将结合附图, 详细描述根据本发明实施例的传输调度请求的方法的 流程。 如图 2所示, 包括如下步骤。
21 , 基于接收到的调度请求配置, 用户设备确定用于传输调度请求信息 的物理上行控制信道资源, 其中所述调度请求信息用于所述用户设备向基站 请求上行资源。
22, 用户设备在确定的所述物理上行控制信道资源上传输所述调度请求 信息。
这里, 物理上行控制信道资源为宏基站对应的上行载波上的物理上行控 制信道资源。
通过调度请求配置指示的频域、 时域及其组合等, 用户设备配置用于传 输调度请求信息的上行传输资源, 例如子帧、 信道等。
在一种实施方式中, 当调度请求配置包括多个指示物理上行控制信道的 参数, 用户设备根据所述参数确定传输调度请求信息的物理上行控制信道, 于是用户设备在所述物理上行控制信道上传输向对应基站请求上行资源的 调度请求信息。 也就是, 当调度请求配置指示了频域配置时, 用户设备可以 进行频域配置以在物理上行控制信道资源上传输调度请求信息。
其中, 以系统中仅存在两个基站(例如 , 一个宏基站和一个微基站) 为 例, 当所述多个指示物理上行控制信道的参数包括第一物理上行控制信道的 参数和第二物理上行控制信道的参数, 其中所述第一物理上行控制信道的参 数用于指示传输向第一基站请求上行资源的调度请求信息的物理上行控制 信道, 所述第二物理上行控制信道的参数用于指示传输向第二基站请求上行 资源的调度请求信息的物理上行控制信道。 那么, 用户设备在所述第一物理 上行控制信道的参数指示的物理上行控制信道上传输向第一基站请求上行 资源的调度请求信息,在所述第二物理上行控制信道的参数指示的物理上行 控制信道上传输向第二基站请求上行资源的调度请求信息。
在另一实施方式中, 当所述调度请求配置包括指示调度请求信息的传输 周期和子帧偏移的参数, 用户设备根据所述指示调度请求信息的传输周期和 子帧偏移的参数确定传输向不同基站请求上行资源的调度请求信息的子帧。 用户设备在确定的子帧上传输向对应的基站请求上行资源的调度请求信息。 也就是, 当调度请求配置指示了时域配置时, 用户设备可以进行时域配置以 在物理上行控制信道资源上传输调度请求信息。
其中, 以系统中仅存在两个基站(例如, 一个宏基站和一个微基站) 为 例, 当所述调度请求配置包括指示调度请求信息的传输周期和子帧偏移的参 数, 用户设备根据所述指示调度请求信息的传输周期和子帧偏移的参数确定 传输向不同基站请求上行资源的调度请求信息的子帧。 例如, 用户设备在所 述子帧中的偶数位置上的子帧上传输向第一基站请求上行资源的调度请求 信息, 所述用户设备在所述子帧中奇数位置上的子帧上传输向第二基站请求 上行资源的调度请求信息。
或者, 在另一实施方式中, 当所述调度请求配置包括多个调度请求子配 置, 其中每个所述调度请求子配置包括指示请求对应的基站的上行资源的调 度请求信息的传输周期和子帧偏移的参数; 于是用户设备根据所述指示请求 对应的基站的上行资源的调度请求信息的传输周期和子帧偏移的参数, 确定 用于传输请求对应的基站的上行资源的调度请求信息的子帧。 用户设备在所 述子帧上传输请求对应的基站的上行资源的调度请求信息。
此外, 可选地, 每个所述调度请求子配置还包括指示物理上行控制信道 的参数, 于是用户设备可以根据该参数确定传输调度请求信息的物理上行控 制信道。 用户设备在所述子帧和所述物理上行控制信道上传输请求对应的基 站的上行资源的调度请求信息。
可见, 在该实施方式中, 通过多个调度请求子配置为用户设备指示时域 配置或者时域与频率配置时, 用户设备可以进行时域配置以在物理上行控制 信道资源上传输调度请求信息, 或者用户设备可以进行时域与频域配置以在 物理上行控制信道资源上传输调度请求信息。
在用户设备根据基站指示的调度请求配置进行上行传输资源配置的情 况下, 用户设备能够将调度奇求信息传送给基站且基站能够正确地接收到调 度请求信息。 此外, 也可以用户设备标记出将发送给不同基站的调度请求信 息, 这样当基站接收到用户设备发送的调度请求信息之后, 通过解析出标记 便可确定上述调度请求信息是否是发送给自己的。
具体而言, 用户设备确定待传输的调度请求信息, 然后为所述待传输的 调度请求信息设置信息比特, 所述信息比特用于指示所述调度请求信息请求 对应的基站的上行资源, 用户设备再在确定的所述物理上行控制信道资源上 传输所述调度请求信息。
以系统中仅存在两个基站(例如, 一个宏基站和一个微基站)为例, 若 待传输的调度请求信息用于向第一基站请求上行资源, 则所述待传输的调度 请求信息对应的信息比特为 0; 若待传输的调度请求信息用于向第二基站请 求上行资源, 则所述待传输的调度请求信息对应的信息比特为 1。 或者, 若 待传输的调度请求信息用于向第一基站请求上行资源, 则所述待传输的调度 请求信息对应的信息比特为 10; 若待传输的调度请求信息用于向第二基站请 求上行资源, 则所述待传输的调度请求信息对应的信息比特为 01; 若待传输 的调度请求信息用于同时向第一基站和第二基站请求上行资源, 则所述待传 输的调度请求信息对应的信息比特为 11。
若待传输的调度请求信息包括多个用于向不同基站请求上行资源的调 度请求信息, 则用户设备根据预设的优先级确定优先级最高的调度请求信 息, 传输该优先级最高的调度请求信息, 丢弃其他调度请求信息。 所述预设 的优先级是载波的优先级、 高层通过半静态信令通知的优先级、 或者基站优 先级。 当预设的优先级为载波的优先级时, 例如以该载波的优先级从高到低 的顺序作为载波索引递增的顺序, 即载波索引小的载波具有较高优先级。 或 者, 当预设的优先级为基站优先级, 则基站优先级为宏基站的优先级高于微 基站的优先级。
由上可知, 本发明实施例能够通过调度请求配置 (例如包括时域配置、 频域配置及其组合配置)、 调度请求信息的内容标识及其组合等解决在 MSA 场景下如何传输调度请求信息的问题, 从而避免延迟上行数据得到服务的时 间, 提高用户感受。
以下结合图 3详细描述基站侧的传输调度请求的传输方法, 由于基站侧 的操作与用户设备侧的操作是相互对应的, 在此省略重复的内容。 如图 3所 示, 方法包括如下步骤。
31 ,基站基于调度请求配置确定用户设备传输调度请求信息的物理上行 控制信道资源;
32, 基站在所述物理上行控制信道资源上检测所述调度请求信息。 例如, 若基站为宏基站, 则宏基站通过高层信令给用户设备发送调度请 求配置, 然后基于所述调度请求配置确定用户设备传输调度请求信息的物理 上行控制信道资源,再在所述物理上行控制信道资源上检测所述调度请求信 息。
可选地, 若基站为微基站, 则微基站具有接收在宏基站上行载波上发送 的物理上行控制信道的能力。因此,微基站接收宏基站发送的调度请求配置, 然后基于所述调度请求配置确定用户设备传输调度请求信息的物理上行控 制信道资源, 再在所述物理上行控制信道资源上检测所述调度请求信息。 进 一步地, 微基站在所述物理上行控制信道资源上检测所述调度请求信息, 其 中所述物理上行控制信道资源指示的物理上行控制信道位于宏基站对应的 上行载波上。
以下的描述不再区分宏基站和微基站, 其上执行步骤 31和步骤 32如下 所述。
在第一实施方式中, 当调度请求配置包括多个指示物理上行控制信道的 参数, 且每个所述参数用于指示用户设备传输向对应的基站请求上行资源的 调度请求信息的物理上行控制信道时, 则基站基于所述指示物理上行控制信 道的参数确定用户设备传输的向不同基站请求上行资源的调度请求信息的 物理上行控制信道, 再在所述物理上行控制信道上检测所述调度请求信息。
在第二实施方式中, 当所述调度请求配置包括指示调度请求信息的传输 周期和子帧偏移的参数的情况下,基站基于所述指示调度请求信息的传输周 期和子帧偏移的参数确定用户设备传输调度请求信息的子帧, 再在所述子帧 上检测所述调度请求信息。 例如, 以系统中仅存在两个基站(例如, 一个宏 基站和一个微基站)为例, 基站可以在子帧中的奇数或偶数位置上的子帧上 接收调度请求信息。
在第三实施方式中, 当所述调度请求配置包括多个调度请求子配置, 且 每个所述调度请求子配置用于配置用户设备请求对应的基站的上行资源的 调度请求信息时,基站基于所述多个调度请求子配置确定用户设备传输的向 自己请求上行资源的调度请求信息的物理上行控制信道资源, 再在所述调度 请求子配置指示的物理上行控制信道资源上检测所述调度请求信息。
例如, 基站解析所述调度请求信息的信息比特, 其中所述信息比特用于 指示所述调度请求信息请求对应的基站的上行资源。 于是, 基站根据所述信 息比特确定所述调度请求信息是否是用户设备传输给自己的调度请求信息。 以系统中仅存在两个基站(例如, 一个宏基站和一个微基站)为例, 若解析 的信息比特为 0, 则所述调度请求信息用于向第一基站请求上行资源; 若解 析的调度请求信息的信息比特为 1 , 则所述调度请求信息用于向第二基站请 求上行资源; 或者若解析的信息比特为 10则所述调度请求信息用于向第一基 站请求上行资源; 若解析的信息比特为 01 , 则所述调度请求信息用于向第二 基站请求上行资源; 若解析的信息比特为 11 , 则所述调度请求信息用于同时 向第一基站和第二基站请求上行资源。
由上可知, 本发明实施例能够通过调度请求配置 (例如包括时域配置、 频域配置及其组合配置)、 调度请求信息的内容标识及其组合等解决在 MSA 场景下如何传输调度请求信息的问题, 从而避免延迟上行数据得到服务的时 间, 提高用户感受。
以上三个实施方式可以相互结合, 即将频域配置、 时域配置和调度请求 信息的内容标识进行两两结合或全部结合, 结合得到的实施方式也可以用于 传输调度请求信息。 下面将给出具体实施例, 以系统中仅存在两个基站(例 如, 一个宏基站和一个 T基站)为例, 详细描述如何设置调度请求配置, 以 便依据调度请求配置实现调度请求信息的传输。 可以理解, 以下提出的具体 实施例仅是示例性的, 本领域技术人员可以在理解了上述发明精神的基础上 得出其他的具体实施例。 具体实施例一:
步骤 1: 用户设备接收调度请求配置。
该步驟 1中, 用户设备接收基站通过高层信令通知的调度请求配置, 该 基站可以是宏基站。 该调度请求配置可以包括第一调度请求配置和第二调度 请求配置, 且第一调度请求配置用于配置请求第一基站上行资源的调度请求 信息, 第二调度请求配置用于配置请求第二基站上行资源的调度请求信息。 第一调度请求配置包括指示请求第一基站上行资源的调度请求信息的传输 周期和子帧偏移的参数, 用户设备根据该参数确定调度请求信息的传输周期 和子帧偏移,根据确定的传输周期和子帧偏移确定用于传输请求第一基站上 行资源的调度请求信息的子帧; 第二调度请求配置包括指示请求第二基站上 行资源的调度请求信息的传输周期和子帧偏移的参数, 用户设备根据该参数 确定调度请求信息的传输周期和子帧偏移,根据确定的传输周期和子帧偏移 确定用于传输请求第二基站上行资源的调度请求信息的子帧。 第一调度请求 配置还可以包括指示物理上行控制信道资源的参数, 该物理上行控制信道用 于传输请求第一基站上行资源的调度请求信息; 第二调度请求配置还可以包 括指示物理上行控制信道资源的参数, 该物理上行控制信道用于传输请求第 二基站上行资源的调度请求信息。 这里, 第一调度请求配置和第二调度请求 配置指示的物理上行控制信道资源可以相同也可以不同。
若第一调度请求配置和第二调度请求配置指示的物理上行控制信道资 源相同, 则该步驟 1中的调度请求配置指示在相同的物理上行控制信道及不 同的子帧分别传输请求第一基站上行资源的调度请求信息和请求第二基站 上行资源的调度请求信息。 若第一调度请求配置和第二调度请求配置指示的 物理上行控制信道资源不同, 则该步骤 1中的调度请求配置指示在不同的物 理上行控制信道及不同的子帧分别传输请求第一基站上行资源的调度请求 信息和请求第二基站上行资源的调度请求信息。
如上所述, 第一基站可以是宏基站, 第二基站可以是微基站。
步骤 2: 用户设备确定待传输的调度请求信息。
该步驟 2中, 用户设备确定待传输的调度请求信息。 用户设备首先根据 步骤 1中接收到的调度请求配置信息确定当前子帧是用于传输请求第一基站 上行资源的调度请求信息的子帧还是用于传输请求第二基站上行资源的调 度请求信息的子帧。 若当前子帧为传输请求第一基站上行资源的调度请求信 息的子帧, 且用户设备需要传输请求第一基站上行资源的调度请求信息, 则 该步骤 2确定的待传输的调度请求信息为 ^0) = 1, WO)为待传输的调制符号; 若当前子帧为传输请求第二基站上行资源的调度请求信息的子帧, 且用户设 备需要传输请求第二基站上行资源的调度请求信息, 则该步骤 2确定的待传 输的调度请求信息为 (0) = 1, d(0)为待传输的调制符号。
若根据步驟 1中的调度请求配置, 当前子帧待传输的调度请求信息包括 多个用于请求不同基站上行资源的调度请求信息, 则根据预设的优先级确定 优先级最高的调度请求信息, 传输该优先级最高的调度请求信息, 丟弃其他 调度请求信息。 预设的优先级可以为载波的优先级, 或高层通过半静态信令 通知的优先级, 或基站优先级。
步骤 3: 用户设备基于步骤 1中接收到的调度请求配置确定物理上行控制 信道资源, 该物理上行控制信道资源用于传输所述调度请求信息。
若步骤 1中的第一调度请求配置和第二调度请求配置中包括指示物理上 行控制信道资源的参数, 则步驟 3根据步骤 1中的调度请求配置中包括的指示 物理上行控制信道资源的参数获取物理上行控制信道资源。 若第一调度请求 配置和第二调度请求配置中不包括指示物理上行控制信道资源的参数, 则若 当前子帧为传输请求第一基站上行资源的调度请求信息的子帧, 则该步骤 3 根据第一调度请求配置中指示的请求第一基站上行资源的调度请求信息的 传输周期和子帧偏移的参数获取物理上行控制信道资源, 若当前子帧为传输 请求第二基站上行资源的调度请求信息的子帧, 则该步骤 3根据第二调度请 求配置中指示的请求第二基站上行资源的调度请求信息的传输周期和子帧 偏移的参数获取物理上行控制信道资源。
步骤 4: 用户设备在步骤 3确定的物理上行控制信道资源上传输调度请求 信息。
该步骤 4中, 用户设备在步骤 3确定的物理上行控制信道资源上将调度请 求信息发送给基站。 发送方法为现有技术, 此处不再赘述。
步骤 5: 基站对用户设备传输的调度请求信息进行检测。 该步骤 5又可包 括如下几个步骤:
