在长期演进技术的后续演进(LTE-A, LTE- Advanced ) 中, 引入了多 载波聚合技术, 即一个小区内有多个不同频率 (段) 的载波, 这些载波频 率之间可以是连续的或离散的, 网络侧同时使用两个或两个以上的载波为 一个 UE发送数据; UE同时在两个或者两个以上的载波上接收数据。 根据 目前的标准制定进度, 下面的结论被标准组织采纳, 并写入相应的协议。
多载波聚合技术规定如下:
-每个 UE至少支持 2个分量载波(CC, Component Carrier ) 的聚合; -网络侧为 UE分配指示那个是该 UE的主小区 ( Pcell , Primary Cell ) , 那些是该 UE的辅小区 (Scell, Secondary Cell );
-空闲状态的 UE驻留在自己的 Pcell中;
-Pcell始终处于激活状态;
-网络侧能够关闭(也称去激活, 也用 deactivate表示)和开启(也称激 活, 也用 activate表示) UE的 Scell;
-UE 在关闭的 Scell 中不接收物理下行控制信道(PDCCH, Physical Downlink Control Channel );
-UE 在关闭的 Scell 中不接收物理下行共享信道(PDSCH, Physical Downlink Shared Channel );
-UE在关闭的 Scell中不进行下行载波的信道质量测量( CQI, Channel
Quality Indicator )测量;
-Scell初始默认状态为去激活;
-UE仅在 Pcell中接收广播系统信息( BCCH, Broadcast Control Channel ) 和寻呼消息 ( Paging message )。
基于上述的结论我们分析发现存在下面的问题, 具体问题描述如下: 假设有一多媒体广播组播单频网络( MBSFN , Multimedia Broadcast multicast service Single Frequency Network ) 区域正在发送 MBMS业务, 进 一步假设该 MBSFN 区域内的某一些小区有多个 CC, 其中正在使用 CC2 以 MBSFN方式发送 MBMS业务, 不妨假设这个(些) 小区有 3个 CC, 分别记为 CC1、 CC2和 CC3。 进一步假设在这个(些) 小区有部分 UE的 Pcell被配置为 CC2, 部分 UE的 Pcell为 CC1或者 CC3 , 即 CC2对于一些 UE而言是其的 Scell。
上述场景在载波聚合为主要技术的系统中是一个非常常见的场景, 但 是上述场景存在一些问题, 按照现有的载波聚合技术规范要求, 问题为: 网络侧是可以为 UE配置、 关闭和开启其 Scell, 并且现在关闭和开启的条 件是基于与单播业务相关要求来进行判断, 并没有考虑 MBMS业务的相关 要求。 那么, 如果网络侧关闭了一些 UE的 Scell, 并且这些 UE的 Scell正 是 CC2, 那么这些 UE按照现有的技术规范要求, 则不能在其关闭的 Scell ( CC2 ) 中接收 PDCCH、 PDSCH、 BCCH和寻呼消息等, 这些限定最终导 致 UE不能在其 CC2上接收 MBMS业务。 之所以会这样, 主要是因为 UE 不能在关闭的 Scell中接收 PDCCH、 和 BCCH, 且网络侧不知道 UE接收 MBMS的相关信息、 即 UE是否正在接收 MBMS业务, 也不知道 UE的状 态 (连接状态或空闲状态), 这样网络侧在关闭 Scell 时, 并没有参考 UE 的 MBMS业务的接收情况, 导致上述问题的出现。
还有一种情况也会造成 UE无法接收 MBMS业务, 就是 UE想要接收 某一 CC上的 MBMS业务, 但是网络侧为该 UE分配的 CC中不包括该承 载 MBMS业务的 CC。 这样按照现有的技术规范的规定, 该 UE就不能从 该 CC上接收 MBMS业务, 主要也是因为网络侧不了解 UE的接收需求。
通过上面的分析,本发明提出以下完善的技术方案, 以实现 UE在多载 波系统中接收 MBMS业务。 发明内容
有鉴于此,本发明的主要目的在于提供一种载波聚合下 UE接收 MBMS 的方法和装置, 以完善现有的 UE从 CC接收 MBMS业务的技术, 解决由 于网络侧不了解 UE的接收 MBMS业务的需求导致的 UE不能从 CC接收 MBMS业务的问题。 为了实现上述目的, 本发明的技术方案是这样实现的:

图 1为本发明载波聚合下 UE接收 MBMS的方法流程示意图; 图 2为本发明实施例一 UE接收 MBMS的方法流程示意图;
图 3为本发明实施例二 UE接收 MBMS的方法流程示意图。 具体实施方式
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 本发明载波聚合下 UE接收 MBMS的方法如图 1所示,包括如下步驟: 步驟 101, UE确定在自身所处地理位置上能够接收到的所有 CC。 本发明所述的 UE是具有接收 MBMS能力的 UE, 并且具有多载波接 收能力。
UE在一个地理位置上能够接收到一个或多个 CC, 根据多载波聚合技 术的规定,一个 CC对应一个小区。这些 CC中有一个被配置为该 UE的 Pcell; 有多个 CC可能被配置为该 UE的 Scell, UE也可以没有 ScelL
步驟 102, UE确定所有 CC中承载 MBMS的 CC。
此处的实现分为两种情况: 一是: UE根据所有 CC 中每个 CC与自身的关系, 接收每个 CC 的 BCCH,并根据 BCCH确定其中承载 MBMS的 CC。 BCCH至少包括 SIB13 , 还可以包括 MIB和 SIB1 ; UE接收到某个 CC的 BCCH后, 判断 SIB13中 是否含有多播控制信道( MCCH, Multicast Control Channel ) 的配置参数, 如果有, 确定该 CC有 MBMS发送、 即承载 MBMS; 否则, 确定该 CC无 MBMS发送;
一是: 网络侧通过 UE的 Pcell直接告知 UE所有 CC中承载 MBMS的 CC有哪些; UE根据每个承载 MBMS的 CC与自身的关系, 接收每个承载 MBMS的 CC的 BCCH。
上述 CC与 UE的关系, 有以下几种情况:
CC被配置为 UE的 Pcell; 和 /或,
CC被配置为 UE的 Scell、 且 Scell为激活状态; 和 /或,
CC被配置为 UE的 Scell、 且 Scell为去激活状态; 和 /或,
CC没有被配置为 UE的 Pcell和 Scell。
根据上述 CC与 UE的关系: CC被配置为 UE的 Pcell; 或者 CC被配 置为 UE的 Scell、 且 Scell为激活状态; 或者 CC被配置为 UE的 Scell、 且 Scell为去激活状态; 或者 CC没有被配置为 UE的 Pcell和 Scell, 则 UE接 收 CC的 BCCH, 具体为: UE直接从该 CC上接收 BCCH (假设 UE具有 足够的能力支持该 CC的接收)。
CC被配置为 UE的 Pcell; 或者 CC被配置为 UE的 Scell、 且 Scell为 激活状态, 则 UE接收 CC的 BCCH, 具体为: 网络侧通过 UE的 Pcell将 需要接收的 CC的 BCCH发送给 UE。
步驟 103 , UE从承载 MBMS的 CC上接收 MBMS。
UE确定了承载 MBMS的 CC后, 从该 CC上接收 MBMS。
由于 UE已经接收了该 CC的 BCCH ( UE接收 BCCH的场景及方式如 步驟 102所述,此处不再赘述), 则 UE根据 SIB13中 MCCH的配置参数确 定 MCCH的位置、 并接收 MCCH信息; 然后, UE根据 MCCH信息在物 理多播信道(PMCH, Physical Multicast CHannel ) 中接收多播信道调度信 息( MSI, Multicast channel Scheduling Information )和多播传输信道( MTCH, Multicast Traffic Channel ) , 从而完成 MBMS的接收。
另外, 确定 UE感兴趣的 MBMS业务所在的 CC时也可以根据 UE提 供的 MBMS业务的电子节目单选择感兴趣的 MBMS业务, 然后根据电子 节目单中的 MBMS业务相关信息确定选择的 MBMS业务所在的 CC。
对于单播业务(即非 MBMS业务), UE不能在其 Scell中接收 BCCH 和 PDCCH, 这样有利于网络侧的调度和 UE 节能。 本发明中之所以对于 MBMS业务允许 UE在其 Scell中接收 BCCH, 因为 MBMS业务为单向下 行业务, UE不需要与网络侧进行上行交互, 所以直接从 UE的 Scell中接 收 BCCH比较方便, 且便于 UE省电。
通过上述的方式, 实现了 UE在非自己的 Pcell (对应的 CC ) 中接收 MBMS业务, 从而实现了多载波系统中 UE随时在各个 CC中都可以接收 MBMS业务, 并且不需要网络侧把 UE需要接收 MBMS业务所在的 CC配 置为其 Pcell, 实现了 UE在 CC中接收 MBMS与网络侧是否将 UE需要接 收的 MBMS业务所在的 CC配置为 UE的 Pcell或者 Seel无关。这样减少了 网络侧的为 UE配置载波的负担。
下面通过具体实施例来说明本发明的上述方法。
实施例一
假设构成某一 MBSFN区域的一个或多个小区都具有多载波,并且其中 参与 MBSFN区域内的 MBMS发送的 CC为 CC2和 CC4。为了便于后续描 述进行如下约定: MBSFN区域内有 1个 UE (记为 UE1 )需要接收 MBMS, UEl在当前的地理位置上可以接收到 CC1、 CC2、 CC3和 CC4, 其中, CC2 被配置为 UE1的 Pcell; CC1和 CC3被配置为 UE1的 Scell, 其中, CC1为 激活状态, CC3为去激活状态; CC4即不是 UE1的 Scell也不是 UE1的 Pcell。
依据本发明的方法, UE 1接收 MBMS的过程为:
步驟 201、 UE1 先确定在自身当前所处的地理位置上可以接收到哪些 CC, 确定结果即 CC1、 CC2、 CC3和 CC4;
步驟 202、 UE1确定 CC1、 CC2、 CC3和 CC4与自身的关系, 可知, CC2被配置为 UE1的 Pcell, CC1 (激活状态 )和 CC3 (去激活状态 )被配 置为 UE1的 Scell; CC4即不是 UE1的 Scell也不是 UE1的 Pcell;
步银 203、 UE1 ^ CC CC2、 CC3和 CC4的 BCCH, ^口果当前 CC 被配置为 UE的 Pcell; 或者 CC被配置为 UE的 Scell、 且为激活状态; 或 者 CC被配置为 UE的 Scell、 且为去激活状态; 或者 CC没有被配置为 UE 的 Pcell和 Scell时, UE1都可以直接从该 CC上接收其 BCCH, 因此 UE1 直接从 CC1、 CC2、 CC3和 CC4上接收对应的 BCCH;
接收 BCCH时, 可以仅仅接收 MIB、 SIB1 和 SIB13 , 这样可以避免 UE1接收与 MBMS无关的系统信息块。
步驟 204、 UE1可以确定 CC1、 CC2、 CC3和 CC4中承载 MBMS的 CC为 CC2和 CC4, 判断方法如步驟 102中所述, 此处不再赘述;
步驟 205、 UE1从 CC2和 CC4接收 MBMS, 具体的: 以 CC2为例, 根据 CC2中的 SIB13中 MCCH的配置参数即可获知 CC2中 MCCH的位置, 然后接收 MCCH信息, 再根据 MCCH信息在 CC2中的 PMCH中接收 MSI 和 MTCH, 完成 MBMS的接收。
从 CC4接收 MBMS的过程与从 CC2接收 MBMS的过程相同,此处不 再赘述。
由此可见, 按照本发明的方法, UE1不关心网络侧为其配置的 Pcell和 Scell, 可直接从 CC中接收 BCCH, 以此确定承载 MBMS的 CC, 并从该 CC上接收 MBMS业务。
实施例二
假设构成某一 MBSFN区域的一个或多个小区都具有多载波,并且其中 参与 MBSFN区域内的 MBMS发送的 CC为 CC1、 CC2、 CC3和 CC4。 为 了便于后续描述进行如下约定: MBSFN区域内有 1个 UE (记为 UE1 ) 需 要接收 MBMS, UE1在当前的地理位置上可以接收到 CC1、 CC2、 CC3和 CC4,其中, CC1被配置为 UE1的 Pcell; CC2和 CC3被配置为 UE1的 Scell, 其中, CC2为激活状态, CC3为去激活状态; CC4即不是 UE1的 Scell也 不是 UE1的 Pcell。
依据本发明的方法, UE1接收 MBMS的过程为:
步驟 301、 UE1 先确定在自身当前所处的地理位置上可以接收到哪些 CC、 即 CC1、 CC2、 CC3和 CC4, 网络侧通过 UE1的 Pcell (即 CC1 )告 知 UE1承载 MBMS的 CC为 CC1、 CC2、 CC3和 CC4;
步驟 302、 UE1确定承载 MBMS业务的 CC1、 CC2、 CC3和 CC4与自 身的关系, 可知, CC1被配置为 UE1的 Pcell; CC2和 CC3被配置为 UE1 的 Scell, 其中, CC2为激活状态, CC3 为去激活状态; CC4即不是 UE1 的 Scell也不是 UE1的 Pcell;
步驟 303、 UE1接收 CC1、 CC2、 CC3和 CC4的 BCCH, 具体为: 如果 UE要接收的 CC被配置为 UE的 Pcell; 或者 CC被配置为 UE的 ScelL 且为激活状态; 或者 CC被配置为 UE的 Scell、 且为去激活状态; 或者 CC没有被配置为 UE的 Pcell和 Scell时, 即 CC1、 CC2 CC3和 CC4 的情况, UE1可以直接从 CC1、 CC2、 CC3和 CC4上接收对应的 BCCH, 无需请求网络侧配置;接收 BCCH时, 可以仅仅接收 MIB、 SIB 1和 SIB 13 , 这样可以避免 UE1接收与 MBMS无关的系统信息块。
另外, 对于 CC被配置为 UE的 Pcell; 或者 CC被配置为 UE的 Scell、 且所述 Scell为激活状态时, 即 CC1和 CC2的情况, 也可以由网络侧通过 UE1的 Pcell (即 CCl )将 CCl和 CC2的 BCCH发送给 UE1 , 这里可以仅 仅发送 MIB、 SIB 1和 SIB 13。
步驟 304、 UE1从 CC1、 CC2、 CC3和 CC4接收 MBMS, 具体的: 以 CC2为例, 根据 CC2 中的 SIB13 中 MCCH的配置参数即可获知 CC2 中 MCCH的位置, 然后接收 MCCH信息, 再根据 MCCH信息在 CC2 中的 PMCH中接收 MSI和 MTCH, 完成 MBMS的接收。
从 CCl、 CC3和 CC4接收 MBMS的过程与从 CC2接收 MBMS的过程 相同, 此处不再赘述。
由此可见, 按照本发明的方法, UE1不关心网络侧为其配置的 Pcell和
Scell, 可直接从 CC中接收 BCCH, 以此确定承载 MBMS的 CC, 并从该 CC上接收 MBMS业务。
为了实现上述接收 MBMS的方法, 本发明提供了一种接收 MBMS的 装置, 应用于载波聚合下接收 MBMS的 UE中, 该装置包括:
分析模块,用于确定在 UE所处地理位置上 UE能够接收到的所有 CC; 还用于定所有 CC中承载 MBMS的 CC;
接收模块, 用于在承载 MBMS的 CC上接收 MBMS。
其中, 接收模块, 还用于根据 CC与 UE的关系, 接收每个 UE能接收 到的 CC的 BCCH; 分析模块根据 BCCH确定承载 MBMS的 CC;
接收模块, 还用于根据网络侧过 UE的 Pcell告知的所有 CC中每个承 载 MBMS的 CC与 UE的关系, 接收每个 载 MBMS的 CC的 BCCH。
BCCH至少包括 SIB 13 , 还可以包括 MIB和 SIB 1。
分析模块, 还用于判断 CC的 SIB13中是否含有 MCCH的配置参数, 如果有, 确定该 CC有 MBMS发送; 否则, 确定该 CC无 MBMS发送。
接收模块, 还用于根据 CC的 SIB13中 MCCH的配置参数确定 MCCH 的位置、 并接收 MCCH信息; 并根据 MCCH信息在 PMCH中接收 MSI和 MTCH, 完成 MBMS的接收。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
