Description

组成载波管理方法与设备
本申请要求于 2010 年 1 月 30 日提交中国专利局、 申请号为 201010106228.0、发明名称为"组成载波管理方法与设备"的中国专利申请的优 先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域, 尤其涉及一种组成载波管理方法与设备。
背景技术
为了满足 IMT-Advanced (高级国际移动通信)的要求, 支持高达 lGbits/s 的峰值数据速率, 3GPP LTE-ADVANCED ( LTE-A, LTE的继续演进)系统目 前已经同意将载波汇聚(CA, Carrier Aggregation, 又叫载波聚合)技术作为 其扩展系统带宽的方法。 载波汇聚技术将多个组成载波(CC , Component Carrier ) 汇聚成一个较大带宽 (例如, 高于 20MHz ), 以支持高速数据输率。 例如,可使 5个 20MHz的组成载波共同汇聚成为一个具有 100MHz的下行传 输带宽。
为了降低 UE ( User Equipment, 用户设备)盲检测复杂性以及降低小区 间干扰,可从多个 CC中划分出 PDCCH ( Physical Downlink Control Channel , 物理下行控制信道)监听集和 PDSCH ( Physical Downlink Shared Channel, 物 理下行共享信道) 集。 PDSCH集内的 CC是 UE用来在一定时间内进行数据 收发所使用的组成载波, 所述组成载波可以是下行组成载波、 上行组成载波 或上下行组成载波对; PDCCH监听集内的 CC是用于向 UE发送调度信息的 组成载波, 具体地, 所述调度信息用 PDCCH信令进行传输, PDCCH监听集 可以是 PDSCH集的子集。 对于一个 UE, 其 PDCCH监听集, 就是 UE进行 PDCCH监听以获取调度信息的组成载波集合。 例如, 假设当前存在 5个组成 载波, 分别为 CC1至 CC5, PDSCH集可以由 CC2至 CC5 共 4个组成载波构 成, 而 PDCCH监听集可以由 CC2和 CC3两个组成载波构成。 即当 UE使用 CC2至 CC5这四个组成载波进行数据收发时, UE可以只监听 CC2和 CC3的 PDCCH信道以获知 CC2至 CC5上的调度信息。
在激活或配置 CC时, 如何对 PDCCH监听集进行管理并实现对相应 CC的 监听就成为一个问题。

本发明的实施例提供另一种组成载波管理方法, 包括:
接收组成载波激活或配置消息, 通过所述组成载波激活或配置消息获知 需要加入物理下行控制信道监听集的一个或多个组成载波;

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, 所描述的实施例仅仅是本发明一部分实施例, 而 不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
图 1 为本发明实施例提供的一种组成载波管理方法的示意图, 所述方法 包括:

S12: 向用户设备发送组成载波激活或配置消息, 以指示需要加入物理下 行控制信道监听集的一个或多个组成载波。
本实施例在对一个或多个组成载波进行激活或配置时, 将激活或配置的 一个或多个组成载波中需要加入物理下行控制信道监听集的一个或多个组成 载波通知用户设备, 可实时维护用户设备的物理下行控制信道监听集, 保证 用户设备的业务需求, 降低了组成载波的激活时延。 本发明实施例还可以通 过组成载波激活或配置消息指示将已经处于激活状态且未加入 PDCCH监听 集的组成载波加入 PDCCH监听集。
本实施例中所述组成载波激活或配置消息还可用于指示在需要加入物理 下行控制信道监听集的一个或多个组成载波上监听的组成载波, 或需要从物 理下行控制信道监听集中替换或移除的组成载波。
可选地,基站可向用户设备发送物理下行控制信道命令、 MAC控制 PDU 或者 RRC消息, 以激活一个或多个组成载波, 并指示需要加入物理下行控制 信道监听集的一个或多个组成载波。 可利用物理下行控制信道命令、 MAC控 制 PDU或者 RRC消息中的指示信息指示需要加入物理下行控制信道监听集 的一个或多个组成载波, 所述指示信息可以是一个或多个比特位。 可选地, 还可利用物理下行控制信道命令指示在需要加入物理下行控制信道监听集的 一个或多个组成载波上调度的组成载波, 如果有 4个组成载波 A、 B、 C和 D 被激活, 其中组成载波 A和 B需要加入物理下行控制信道监听集, 可进一步 指示在组成载波 A上调度组成载波 C、以及在组成载波 B上调度组成载波 D。 也就是说, 在指示需要加入物理下行控制信道监听集的一个或多个组成载波 的同时, 进一步指示这些被加入物理下行控制信道监听集的一个或多个组成 载波所能调度的组成载波, 即指示新加入物理下行控制信道监听集的一个或 多个组成载波与需要被调度的组成载波之间的一种关联(linkage ) 关系。
所述向用户设备指示需要加入物理下行控制信道监听集的一个或多个组 成载波还可包括: 向用户设备指示需要从物理下行控制信道监听集中替换或 移除的组成载波, 例如, 可利用物理下行控制信道命令中的剩余比特位指示 需要从物理下行控制信道监听集中替换或移除的组成载波。 物理下行控制信 道命令中的比特除了用于指示组成载波激活和物理下行控制信道监听集更 新, 剩余的比特位可用于指示需要从物理下行控制信道监听集中替换或移除 的组成载波, 即如果组成载波 A和 B需要加入物理下行控制信道监听集, 原 物理下行控制信道监听集内组成载波 E和 F可被组成载波 A和 B替换或被移 除。 可选地, 本实施例可复用用于激活的物理下行控制信道命令和用于物理 下行控制信道监听集更新的物理下行控制信道命令, 即利用物理下行控制信 道命令中的一个或多个比特位作为指示信息, 指示所述物理下行控制信道命 令是用于对一个或多个组成载波进行激活、 还是用于物理下行控制信道监听 集的更新。此外, 上述的物理下行控制信道命令也可以用 MAC控制协议数据 单元或者是 RRC消息代替。
可选地, 基站可向用户设备发送无线资源控制信令, 以为用户设备重新 分配或配置一个或多个组成载波, 并指示需要加入物理下行控制信道监听集 的一个或多个组成载波。 所述无线资源控制信令可以是无线资源控制连接重 配置消息。 基站可通过无线资源控制连接重配置消息对用户设备的一个或多 个组成载波进行激活, 即利用无线资源控制信令同时实现组成载波的重配置 和组成载波的激活; 基站也可以在利用无线资源控制信令重配置组成载波之 后, 通过组成载波激活命令实现对组成载波的激活。 本实施例中的基站还可 进一步向用户设备发送物理下行控制信道监听集更新消息, 以指示用户设备 对物理下行控制信道监听集进行更新。 所述物理下行控制信道监听集更新消 息可以是一条单独的物理下行控制信道监听集更新命令, 也可以使用媒体访 问控制协议数据单元或者是物理层控制信令作为所述更新消息。 基站通过无 线资源控制信令指示需要加入物理下行控制信道监听集的一个或多个组成载 波使得用户设备根据指示进行物理下行控制信道监听集更新, 即在更新后的 物理下行控制信道监听集内组成载波上监听获取新激活或配置的组成载波的 调度信息, 在获得所述调度信息后, 再重新指示用户设备进行物理下行控制 信道监听集更新。 例如, 用户设备可依照来自基站的无线资源控制信令的指 示获知新配置的组成载波 A、 B、 C和 D, 基站指示其中组成载波 A和 B需 要加入物理下行控制信道监听集, 并在组成载波 A和 B上发送组成载波 A、 B、 C和 D的调度信息, 则用户设备通过监听组成载波 A和 B得到组成载波 A、 B、 C和 D的调度信息, 后续基站可进一步指示用户设备将组成载波 E加 入物理下行控制信道监听集, 即实现后续的更新。
可选地, 在用户设备从源基站切换到目标基站过程中, 源基站可向用户 设备发送切换命令, 在切换命令中指示需要加入物理下行控制信道监听集的 一个或多个组成载波。

S22: 将需要加入物理下行控制信道监听集的一个或多个组成载波加入物 理下行控制信道监听集。
本实施例在接收组成载波激活或配置消息时, 获知哪些组成载波需要加 入物理下行控制信道监听集, 并实时更新维护所述物理下行控制信道监听集, 保证用户设备的业务需求, 降低了组成载波的激活时延。 在本实施例中, UE 通过接收组成载波激活或配置消息获知需要激活或配置的一个或多个组成载 波。 所述需要加入物理下行控制信道监听集的一个或多个组成载波可以是所 述激活或配置的一个或多个组成载波中的全部或部分组成载波。 本发明实施 例还可以根据来自基站的指示消息获知需要将已经处于激活状态且未加入 PDCCH监听集的组成载波加入 PDCCH监听集。
可选地, 用户设备可从基站接收物理下行控制信道命令, 获知需要激活 的一个或多个组成载波、 以及需要加入物理下行控制信道监听集的一个或多 个组成载波。 需要加入物理下行控制信道监听集的一个或多个组成载波可以 是激活的组成载波中的部分载波。 可选的, 用户设备可通过物理下行控制信 道命令中的一个或多个比特的指示获知需要加入物理下行控制信道监听集的 一个或多个组成载波。 可选地, UE可在完成物理下行控制信道监听集更新后 向基站反馈物理下行控制信道监听集更新确认消息。 用户设备还可通过所述 物理下行控制信道命令获知在需要加入物理下行控制信道监听集的一个或多 个组成载波上调度的组成载波, 和 /或获知需要从物理下行控制信道监听集中 替换或移除的组成载波。 用户设备可在接收所述物理下行控制信道命令后, 通过该命令中包含的指示信息获知该物理下行控制信道命令是用于对一个或 多个组成载波进行激活、 还是用于物理下行控制信道监听集的更新。 此外, 上述的物理下行控制信道命令也可以用 MAC控制协议数据单元或者是 RRC 消息代替。
可选地, 用户设备可接收基站发送的无线资源控制信令, 获知基站为该 用户设备配置的组成载波、 以及需要加入物理下行控制信道监听集的一个或 多个组成载波。 无线资源控制信令还可包括组成载波激活功能, 使用户设备 获知哪些组成载波需要激活, 并激活所述组成载波。 用户设备也可获取单独 的组成载波激活命令, 并激活相应组成载波。 用户设备通过获取无线资源控 制信令得知需要加入物理下行控制信道监听集的一个或多个组成载波, 并根 据指示进行物理下行控制信道监听集更新, 即在更新后的物理下行控制信道 监听集内组成载波上监听获取新激活或配置的组成载波的调度信息。
可选地, 在用户设备从源基站切换到目标基站过程中, 可接收源基站发 送的切换命令, 并通过切换命令获知需要加入物理下行控制信道监听集的一 个或多个组成载波。
可选地, 用户设备在完成物理下行控制信道监听集更新后, 后续可进一 步获取来自基站的物理下行控制信道监听集更新命令, 并根据所述命令的指 示进行物理下行控制信道监听集的更新。
图 3a为本发明实施例提供的一种组成载波管理方法的简化流程示意图, 所述方法包括:
S31a: 基站向用户设备发送物理下行控制信道命令, 以激活一个或多个 组成载波、 并指示需要加入物理下行控制信道监听集的一个或多个组成载波。
可选地, 基站(eNB, eNodeB )可向 UE发送 PDCCH命令, 以为 UE激 活一个或多个组成载波, 并在该 PDCCH命令中用一个或多个比特(Bit )指 示是否需要在激活一个组成载波的同时将该组成载波加入到 PDCCH监听集 中。 eNB可通过将所述一个或多个 CC加入 PDSCH集来激活所述 CC, 被激 活的 CC能够用于数据传送。 可选地, eNB也可以分别指示多个新激活的组 成载波中每个组成载波是否需要加入 PDCCH监听集, 例如, eNB可以分别 使用一个 bit指示每个组成载波是否需要加入 PDCCH监听集; 另外, eNB也 可以集中指示这些新激活的组成载波是否需要加入到 PDCCH监听集中, 即 eNB可以仅仅使用一个 bit指示这些被激活的组成载波是否被加入 PDCCH监 听集中。 如果一个新激活的组成载波被加入到 PDCCH监听集中, 则 eNB可 以进一步指示在该新加入 PDCCH监听集的组成载波可以调度的其他组成载 波的信息, 所述其他组成载波的信息包含这些组成载波的标识符、 频率信息 或者 PCI ( Physical Cell Identity, 物理小区标识)等信息中的一个或多个, 即 表示该新加入 PDCCH监听集的组成载波可以调度哪些其他的组成载波。所述 调度的其他组成载波可以包括新激活的其它组成载波或者原 PDSCH 集中的 其他组成载波。 如果新激活的组成载波没有被加入到 PDCCH监听集中, 则 eNB可以进一步指示这些未加入 PDCCH监听集的新激活的组成载波具体由 PDCCH监听集中的哪个或哪些组成载波进行调度。 总之, eNB可以向 UE指 示 PDCCH监听集内的 CC和 PDSCH集内的 CC的关联( linkage ) 关系, 即 如果 PDCCH监听集内的一个组成载波与 PDSCH集内的一个载波存在 linkage 关系, 即表明 PDCCH监听集内的这个组成载波可以调度存在 linkage关系的 PDSCH集内的组成载波。
此外, 如果新激活的组成载波为一个扩展 CC ( Extension CC )或者 CC 分段( CC segment ) ,所述扩展 CC或者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道,不能进行自行调度,而只能依附于其它具有 PDCCH 信道的 CC来控制而进行调度使用的 CC。 即需要在所述其它具有 PDCCH信 成载波的 PDCCH命令中进一步指示调度该扩展 CC或者 CC分段的组成载波。 所述调度该扩展 CC或者 CC分段的组成载波, 可以是当前 PDCCH监听集内 的组成载波, 也可以是该激活组成载波的 PDCCH命令中指示的需要加入 PDCCH监听集中的组成载波。
可选地, eNB可复用用于载波激活或去激活 CC的 PDCCH命令与用于 PDCCH监听集更新的 PDCCH命令, 即在 PDCCH命令中, 可使用一个指示 信息, 例如一个 bit, 指示当前的 PDCCH命令是用于组成载波的激活, 还是 用于 PDCCH监听集的更新。例如,当所述指示 bit为 1时,可以表示该 PDCCH 命令用于 CC的激活, 同时在 PDCCH命令中指示 UE需要对 PDCCH监听集 进行更新; 而当所述指示 bit为 0时, 则该 PDCCH命令可用于 PDCCH监听 集的更新。
可选地, eNB也可以在为 UE激活一个或多个组成载波的同时, 将 UE当 前 PDCCH监听集中的部分或全部 CC进行替换或移除, 即 eNB使用 PDCCH 命令在为 UE激活新的组成载波的同时,将需要从 PDCCH监听集中替换或移 除的一个或多个 CC的标示符、 以及替换或移除的指示信息发送给 UE。
可选择地, eNB可以在将当前 PDCCH监听集中一个或多个 CC从 PDCCH 监听集中移除时, 在该 PDCCH命令中指示是否需要将所述 CC从 PDSCH监 听集中移除, 即 eNB可指示是否去激活这些从 PDCCH监听集中移除的 CC。 如果一个 CC被从 PDSCH监听集中移除, 其将被去激活, 即不再被用于传送 数据。
S32a: 用户设备按照基站的所述指示, 将需要加入物理下行控制信道监 听集的一个或多个组成载波加入物理下行控制信道监听集。
UE在接收到 eNB发送的 PDCCH命令后, 可根据 PDCCH命令的指示确 定新激活的 CC, 以及是否需要将新激活的一个或多个组成载波加入 PDCCH 监听集, 即 UE确定是否对当前的 PDCCH监听集进行更新, 并将需要加入 PDCCH监听集的 CC加入 PDCCH监听集。
S33a: 用户设备发送物理下行控制信道监听集更新确认消息给所述基站。 可选地, UE在更新 PDCCH监听集后, 可以发送 PDCCH监听集更新确认指 示消息给 eNB, 该指示消息可以是一个或多个 bits。 S33在本实施例中只是可 选过程。
本实施例中基站在激活组成载波的同时通过组成载波激活或配置消息指 示需要加入物理下行控制信道监听集的一个或多个组成载波, 使得用户设备 能够更新物理下行控制信道监听集, 实现对 PDCCH的监听, 降低了组成载波 的激活时延。
在本实施例中, 为了降低 UE盲检测 PDCCH的次数, 可以基于现有 LTE ( Long Term Evolution , 长期演进) 的 PDCCH DCI ( Downlink Control Information, 下行控制信息 )格式来重新设计 PDCCH DCI格式。 在 LTE中, UE在检测 PDCCH时, 需要考虑所检测的 PDCCH中的信息是否为合法的数 据, 例如, PDCCH信息中指示 PUSCH ( Physical Uplink Shared Channel, 物 理上行共享信道) RB ( Resource Block, 资源块)数可设为 2、 3或 5的倍数, 称为 PUSCH RB分配数,如果 UE检测到 PUSCH RB数不同于 PUSCH RB分 配数时, 则认为该 PDCCH为无效的 PDCCH。 对于 LTE-A UE, 则可以在重 新设计的 PDCCH DCI格式中使用非 PUSCH RB分配数(如非 2、 3或 5倍数 的 PUSCH RB数 ) , 以指示 LTE-A UE该 PDCCH用于 CC的激活或去激活, 或者指示 PDCCH监听集的内 CC的增加、 删除或重配置等。 具体地, 可在重 新设计的 DCI中的剩余 bits中包括上述实施例中提到的激活的 CC的标识符 以及这些新激活的 CC是否被加入到 PDCCH监听集中的指示信息, 或者, 所 述剩余 bits中可以包括 PDCCH监听集内需要增加、删除或者重配置的 CC的 标识符。
另外, 也可以在继承系统的物理下行控制信道中增加新的比特指示信息 来指示所述物理下行控制信道命令是用于在新系统中激活一个或多个组成载 波和用于物理下行控制信道监听集更新, 然后在 DCI中的剩余 bits中包括上 述实施例中提到的激活的 CC的标识符以及这些新激活的 CC是否被加入到 PDCCH监听集中的指示信息, 或者, 所述剩余 bits中可以包括 PDCCH监听 集内需要增加、删除或者重配置的 CC的标识符。所述新系统可以是对所述继 承系统的进一步发展。
可选地, 可利用继承系统的物理下行控制信道中的预留比特指示信息来 指示所述物理下行控制信道命令是用于在新的系统中激活一个或多个组成载 波和用于物理下行控制信道监听集更新, 然后在 DCI中的其他剩余 bits中包 括上述实施例中提到的激活的 CC的标识符以及这些新激活的 CC是否被加入 到 PDCCH监听集中的指示信息, 或者, 所述剩余 bits中可以包括 PDCCH监 听集内需要增加、 删除或者重配置的 CC的标识符。
另外, 在连接过程中, 当 eNB使用 PDCCH命令去激活一个或者多个 CC 时, 同样可以对 PDCCH监听集进行维护: 即在使用 PDCCH命令将一个或多 个 CC去激活时对 UE的 PDCCH监听集进行重新更新, eNB指示 UE对 PDCCH 监听集内的 CC进行增加、 删除或替换。 可选地, 在去激活 CC时, 如果所述 被去激活的 CC属于 PDCCH监听集, eNB可指示 UE将该 CC从 PDCCH监 听集中移除, 并根据当前的 CC配置情况, 对 PDCCH监听集内的 CC进行重 新分配, 即对 PDCCH监听集内的 CC进行增加、 删除或替换, 并在该去激活 CC的 PDCCH命令中将更新信息通知 UE, 然后 UE基于 eNB指示的更新信 息对 PDCCH监听集内的 CC进行增加、 删除或替换。
图 3b 为本发明实施例提供的另一种组成载波管理方法的简化流程示意 图, 所述方法包括:
S31b: 基站向用户设备发送媒体接入控制控制协议数据单元, 以激活一 个或多个组成载波、 并指示需要加入物理下行控制信道监听集的一个或多个 组成载波。
具体地,基站( eNB, eNodeB )可向 UE发送一 MAC CE ( Medium Access Control - Control Element,媒体接入控制控制单元), 以为 UE激活一个或多个 组成载波, 并在该 MAC CE中指示是否需要在激活一个组成载波的同时将该 组成载波加入到 PDCCH监听集中。 eNB 可通过将所述一个或多个 CC加入 PDSCH集来激活所述 CC, 被激活的 CC能够用于数据传送。 可选地, eNB 也可以分别指示多个新激活的组成载波中每个组成载波是否需要加入 PDCCH监听集, eNB也可以集中指示这些新激活的组成载波是否需要加入到 PDCCH监听集中。 如果一个新激活的组成载波被加入到 PDCCH监听集中, 则 eNB可以进一步指示在该新加入 PDCCH监听集的组成载波可以调度的其 他组成载波的信息, 所述其他组成载波的信息包含这些组成载波的标识符、 频率信息或者 PCI等信息中的一个或多个,即表示该新加入 PDCCH监听集的 组成载波可以调度哪些其他的组成载波。 所述调度的其他组成载波可以包括 新激活的其它组成载波或者原 PDSCH集中的其他组成载波。如果新激活的组 成载波没有被加入到 PDCCH监听集中, 则 eNB可以进一步指示这些未加入 PDCCH监听集的新激活的组成载波具体由 PDCCH监听集中的哪个或哪些组 成载波进行调度。总之, eNB可以向 UE指示 PDCCH监听集内的 CC和 PDSCH 集内的 CC的关联( linkage )关系, 即如果 PDCCH监听集内的一个组成载波 与 PDSCH集内的一个载波存在 linkage关系, 即表明 PDCCH监听集内的这 个组成载波可以调度存在 linkage关系的 PDSCH集内的组成载波。
此外, 如果新激活的组成载波为一个扩展 CC ( Extension CC )或者 CC 分段( CC segment ) ,所述扩展 CC或者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道, 不能进行自行调度而只能依附于其它具有 PDCCH 信道的 CC控制而进行调度使用的 CC, 即需要在所述其它 CC上获取所述扩 展 CC的调度信息, 则 eNB可以在激活组成载波的 MAC CE命令中进一步指 示调度该扩展 CC的组成载波。 所述调度该扩展 CC的组成载波, 可以是当前 PDCCH监听集内的组成载波也可以是该激活组成载波的 MAC CE命令中指 示的需要加入 PDCCH监听集中的组成载波。
可选地, eNB 可复用用于载波激活或去激活 CC 的 MAC CE 与用于 PDCCH监听集更新的 MAC CE, 即在 MAC CE命令中, 可使用一个指示信 息指示当前的 MAC CE命令是用于组成载波的激活, 还是用于 PDCCH监听 集的更新。
可选地, eNB也可以在为 UE激活一个或多个组成载波的同时, 将 UE当 前 PDCCH监听集中的部分或全部 CC进行替换或移除,即 eNB使用 MAC CE 命令在为 UE激活新的组成载波的同时,将需要从 PDCCH监听集中替换或移 除的一个或多个 CC的标示符、 以及替换或移除的指示信息发送给 UE。
可选择地, eNB可以在将当前 PDCCH监听集中一个或多个 CC从 PDCCH 监听集中移除时,在该 MAC CE命令中指示是否需要将所述 CC从 PDSCH监 听集中移除, 即 eNB可指示是否去激活这些从 PDCCH监听集中移除的 CC。 如果一个 CC被从 PDSCH监听集中移除, 其将被去激活, 即不再被用于传送 数据。 S32b: 用户设备按照基站的所述指示, 将需要加入物理下行控制信道监 听集的一个或多个组成载波加入物理下行控制信道监听集。
UE在接收到 eNB发送的 MAC CE命令后, 可根据 MAC CE命令的指示 确定新激活的 CC , 以及是否需要将新激活的一个或多个组成载波加入 PDCCH监听集, 即 UE确定是否对当前的 PDCCH监听集进行更新, 并将需 要加入 PDCCH监听集的 CC加入 PDCCH监听集。
S33b: 用户设备发送物理下行控制信道监听集更新确认消息给所述基站。 可选地, UE在更新 PDCCH监听集后, 可以发送 PDCCH监听集更新确认指 示消息给 eNB, 该过程 S33b为可选步骤。
另夕卜,在连接过程中, 当 eNB使用 MAC CE去激活一个或者多个 CC时, 同样可以对 PDCCH监听集进行维护: 即在使用 MAC CE将一个或多个 CC 去激活时对 UE的 PDCCH监听集进行重新更新, eNB指示 UE对 PDCCH监 听集内的 CC进行增加、 删除或替换。 可选地, 在去激活 CC时, 如果所述被 去激活的 CC属于 PDCCH监听集, eNB可指示 UE将该 CC从 PDCCH监听 集中移除, 并根据当前的 CC配置情况, 对 PDCCH监听集内的 CC进行重新 分配, 即对 PDCCH监听集内的 CC进行增加、 删除或替换, 并在该去激活 CC的 MAC CE中将更新信息通知 UE, 然后 UE基于 eNB指示的更新信息对 PDCCH监听集内的 CC进行增加、 删除或替换。
图 4为本发明实施例提供的另一种组成载波管理方法的简化流程示意图, 所述方法包括:
S41 : 基站向用户设备发送无线资源控制连接重配置消息, 以指示需要加 入物理下行控制信道监听集的一个或多个组成载波。
eNB向 UE发送的 RRC连接重配置消息中可包含新分配的或重新配置的 一个或多个 CC在被激活时是否需要加入 PDCCH监听集的指示信息。 此外, 该 RRC连接重配置消息中可以进一步包含那些激活时不被加入 PDCCH监听 集的 CC应该由哪些 CC进行调度的指示信息, 所述用于调度的 CC可以是原 PDCCH监听集内的 CC或者是激活时需要加入 PDCCH监听集的 CC。也就是 说, 激活时不被加入 PDCCH监听集的 CC与当前 PDCCH监听集内的 CC间 可存在 linkage关系, 或者激活时不被加入 PDCCH监听集的 CC与激活时需 要加入 PDCCH监听集的 CC之间存在 linkage关系。
S42: 用户设备从基站接收组成载波激活命令。
S43: 用户设备根据基站的所述指示, 将需要加入物理下行控制信道监听 集的一个或多个组成载波加入物理下行控制信道监听集。
UE在接收到 eNB发送的激活一个或多个组成载波的命令时, 如果该 CC 在 RRC连接重配置消息中被指示加入 PDCCH集合, 则 UE将该 CC加入 PDCCH监听集;如果该 CC在 RRC连接重配置时被指示不加入 PDCCH集合, 即 UE仅将该 CC加入 PDSCH CC集合, 即仅对所述 CC进行激活。
此外, 如果新激活的组成载波为一个扩展 CC ( Extension CC )或者 CC 分段( CC segment ) ,所述扩展 CC或者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道, 不能进行自行调度而只能依附于其它具有 PDCCH 信道的 CC控制而进行调度使用的 CC, 即需要在所述其它 CC上获取所述扩 展 CC的调度信息, 则 eNB可以在组成载波激活命令中进一步指示调度该扩 展 CC的组成载波。 所述调度该扩展 CC的组成载波, 可以是当前 PDCCH监 听集内的组成载波也可以是该组成载波激活命令中指示的需要加入 PDCCH 监听集中的组成载波。
S44: 进一步地, 在 UE连接的过程中, 基站可以继续向用户设备发送物 理下行控制信道监听集更新命令,以更新 UE的物理下行控制信道监听集内的 组成载波。
可选地, eNB可以继续使用一个 RRC消息、 MAC控制 PDU或者物理层 信令进行 PDCCH监听集的维护或更新。 另外, eNB也可以使用 RRC连接重 配置消息对处于配置状态的组成载波在激活时需要加入 PDCCH监听集的 CC进行重新设置, 并使用 RRC连接重配置消息向 UE通知重新设置的一个 或多个 CC是否需要在激活时加入 PDCCH监听集的指示信息。也就是说, eNB 可以在某个配置给 UE的 CC被激活前, 将为该 CC预配置的是否在激活时加 入 PDCCH监听集的这种预配置信息通过 RRC连接重配置消息进行改变。
可选地, 在连接过程中, eNB可在使用 RRC连接重配置消息将一个或多 个 CC去激活或解配置时对 UE的 PDCCH监听集进行重新更新,即 eNB指示
UE更新 PDCCH监听集内的 CC, 即对 PDCCH监听集内的 CC进行增加、 删 除或替换。 可选地, 在去激活 CC时, 如果所述被去激活的 CC属于 PDCCH 监听集, eNB可指示 UE将该 CC从 PDCCH监听集中移除, 并根据当前的
CC配置情况, 对 PDCCH监听集内的 CC进行重新分配, 即对 PDCCH监听 集内的 CC进行增加、 删除或替换, 并使用 RRC连接重配置消息或者 CC去 激活消息将更新信息通知 UE, 然后 UE基于 eNB指示的更新信息对 PDCCH 监听集内的 CC进行增加、 删除或替换。
或者, 当 eNB从配置的 CC集中移除一个或多个 CC时, eNB根据当前 的 CC配置情况, 对 PDCCH监听集内的 CC进行重新分配, 即对 PDCCH监 听集内的 CC进行增加、删除或其替换,并使用 RRC连接重配置消息或者 CC 去激活消息通知 UE。
另外, eNB也可以对当前处于配置状态的 CC在激活时是否加入 PDCCH 监听集重新进行设置, 并使用 RRC连接重配置消息或者去激活消息向 UE通 知重新设置的指示信息。
该实施例中所述的 RRC连接重配置消息也可以用其它的 RRC消息或者
MAC CE ( Control Element )信令进行代替而执行上述的同样功能, 即该实施 例不限于仅仅使用 RRC连接重配置消息。
本实施例中基站在为 UE进行 CC的 RRC连接重配置时, 指示一个或多 个 CC在激活时是否需要加入 PDCCH监听集, UE在收到 CC激活命令时将 指示的 CC加入 PDCCH监听集, 后续可继续进行 PDCCH监听集的维护, 实 现对 PDCCH的监听。 图 5为本发明实施例提供的另一种组成载波管理方法的简化流程示意图, 所述方法包括:
S51 : 基站向用户设备发送无线资源控制连接重配置消息, 以激活一个或 多个组成载波, 并指示需要加入物理下行控制信道监听集的一个或多个组成 载波。
本实施例与图 4实施例的不同在于, RRC连接重配置消息在实现配置 CC 功能的同时, 还有激活 CC的功能, 即 RRC连接重配置消息同时实现 CC的 配置与激活,同时在该 RRC连接重配置消息中指示哪些 CC需要加入 PDCCH 监听集。 eNB在配置并且激活一个或多个组成载波的同时, 可在 RRC连接重 配置消息中增加是否将这些组成载波中的部分或全部加入到 PDCCH监听集 的指示信息。 可选地, 如果有多个 CC同时被配置并且激活, 则 eNB可以分 别指示其中的每个 CC是否被加入到 PDCCH监听集中;或者也可以仅仅指示 需要被加入 PDCCH监听集内的 CC, 而未经指示的 CC默认不加入 PDCCH 监听集。 eNB 也可以集中指示这些新配置并且激活的组成载波是否在激活的 同时被加入到 PDCCH监听集中, 即 eNB可以使用一个指示信息指示这些被 新配置并且激活的组成载波是否被加入 PDCCH监听集中。
如果新激活的组成载波被加入到 PDCCH监听集中, 则 eNB可以进一步 指示这些被加入 PDCCH监听集的组成载波可以调度的其他组成载波的信息, 所述其他组成载波的信息包含这些组成载波的标识符、 频率信息或者 PCI等 信息中的一个或多个,即表示该新加入 PDCCH监听集的组成载波可以调度哪 些其他的组成载波, 所述调度的其他组成载波可以包括新激活的其它组成载 波或者原 PDSCH集中的其他组成载波。如果新激活的组成载波没有被加入到 PDCCH监听集中,则 eNB可以进一步指示该新激活的组成载波由 PDCCH监 听集中的那个或哪些组成载波进行调度。 总之, eNB可以向 UE指示 PDCCH 监听集内的 CC和 PDSCH集内的 CC的关联( linkage )关系, 即如果 PDCCH 监听集内的一个组成载波与 PDSCH集内的一个载波存在 linkage关系, 即表 明 PDCCH监听集内的这个组成载波可以调度存在 linkage关系的 PDSCH集 内的组成载波。
此外, 如果新激活的组成载波为一个扩展 CC ( Extension CC )或者 CC 分段( CC segment ) ,所述扩展 CC或者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道, 不能进行自行调度而只能依附于其它具有 PDCCH 信道的 CC控制而进行调度使用的 CC, 即需要在所述其它 CC上获取所述扩 展 CC的调度信息,则 eNB可以在激活组成载波的 RRC连接重配置消息中进 一步指示调度该扩展 CC的组成载波。 所述调度该扩展 CC的组成载波, 可以 是当前 PDCCH监听集内的组成载波也可以是 RRC连接重配置消息中指示的 需要加入 PDCCH监听集中的组成载波。
可选地, eNB也可以在使用 RRC连接重配置消息为 UE配置并且激活新 的一个或多个组成载波的同时, 将 UE 当前 PDCCH监听集中的部分或全部 CC进行替换或移除, 即 eNB使用 RRC连接重配置消息在为 UE配置并且激 活新的组成载波的同时,将需要从 PDCCH监听集中被替换或移除的一个或多 个 CC的标示符以及替换或移除的指示信息提供给 UE。
S52: 用户设备根据基站的所述指示, 将需要加入物理下行控制信道监听 集的一个或多个组成载波加入物理下行控制信道监听集。
UE在接收到 eNB发送的 RRC连接重配置消息后, 可根据 RRC连接重 配置消息的指示, 确定将那些被指示的需要加入 PDCCH监听集的新激活的 CC加入 PDCCH监听集, 并对当前的 PDCCH监听集进行更新。
S53: 用户设备向基站发送无线资源控制重配置完成消息。
可选地, UE在更新 PDCCH监听集后, 可以发送 RRC连接重配置完成 消息以指示 PDCCH监听集已经更新完成。
S54: 进一步地, 在连接的过程中, 基站可以继续向用户设备发送物理下 行控制信道监听集更新命令, 指示 UE对物理下行控制信道监听集进行更新。
eNB可以继续使用 RRC连接重配置消息指示 UE进行 PDCCH监听集更 新。 eNB可以在使用 RRC连接重配置消息将一个或多个 CC从 PDCCH监听 集中移除时, 在该 RRC连接重配置消息中指示是否在从 PDCCH监听集中移 除一个或多个 CC的同时将相应 CC也从 PDSCH监听集中移除, 即是否在将 所述 CC从 PDCCH监听集中移除的同时去激活这些 CC。如果 UE当前 PDCCH 监听集中的全部 CC都需要被移除, 则 eNB在移除这些 CC的同时, 可以在 RRC连接重配置消息中为 UE分配用于 PDCCH监听的新 CC。
可选地, 在连接过程中, eNB可在使用 RRC连接重配置消息将一个或多 个 CC去激活时对 UE的 PDCCH监听集进行重新更新, 即 eNB指示 UE更新 PDCCH监听集内的 CC,即对 PDCCH监听集内的 CC进行增加、删除或替换。 可选地,在去激活 CC时,如果所述被去激活的 CC属于 PDCCH监听集, eNB 可指示 UE将该 CC从 PDCCH监听集中移除, 并根据当前的 CC配置情况, 对 PDCCH监听集内的 CC进行重新分配, 即对 PDCCH监听集内的 CC进行 增加、 删除或替换, 并使用 RRC连接重配置消息将更新信息通知 UE, 然后 UE基于 eNB指示的更新信息对 PDCCH监听集内的 CC进行增加、删除或替 换。
本实施例中基站在为 UE进行 CC的 RRC连接重配置时, 激活 CC并指 示一个或多个 CC在激活时是否需要加入 PDCCH监听集, 之后 eNB可继续 对 UE的 CC进行 RRC连接重配置, 以实现 PDCCH监听集的重新更新和维 护。
图 6为本发明实施例提供的另一种组成载波管理方法的简化流程示意图, 所述方法包括:
S61 : 源基站与目标基站进行切换协商。
S62: 源基站向用户设备发送切换命令, 在切换命令中指示需要加入物理 下行控制信道监听集的一个或多个组成载波。
eNB可向 UE发送切换命令, 或者发送带有移动性管理的 RRC连接重配 置消息, 在所述消息中可包含有目标 eNB为 UE配置的一个或多个组成载波 的信息, 以及需要 UE监听的 PDCCH监听集的信息。
此外, 如果新激活的组成载波为一个扩展 CC ( Extension CC )或者 CC 分段( CC segment ) ,所述扩展 CC或者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道, 不能进行自行调度而只能依附于其它具有 PDCCH 信道的 CC控制而进行调度使用的 CC, 即需要在所述其它 CC上获取所述扩 展 CC的调度信息, 则 eNB可以在切换命令中进一步指示调度该扩展 CC的 组成载波。 所述调度该扩展 CC的组成载波, 可以是当前 PDCCH监听集内的 组成载波也可以是切换命令中指示的需要加入 PDCCH监听集中的组成载波。
S63: 用户设备根据所述指示, 将需要加入物理下行控制信道监听集的一 个或多个组成载波加入物理下行控制信道监听集。 eNB随后监听 PDCCH监 听集内 CC, 以获得配置的一个或多个 CC的调度信息。
S64: 用户设备向目标基站发送切换完成消息。
本实施例的 UE在从源基站切换至目标基站时,通过源基站的切换命令获 知 PDCCH监听集的更新信息, 即获知需要加入 PDCCH监听集的 CC, 在收 到 CC激活命令后对 PDCCH监听集更新, 实现对 CC的监听。 本实施例对切 换流程只进行了简略介绍,具体的 UE切换过程还包括其它过程,现有技术对 此有详细描述, 本实施例对此不做介绍。
作为本实施例中过程 S62-S63的一个替代方案, 目标 eNB也可以不在切 换命令中向 UE发送 PDCCH监听集的信息,而是在目标 eNB接收到 UE发送 的切换完成消息以后 (或 RRC连接重配置完成消息), 由目标 eNB向 UE发 送组成载波激活命令并指示需要加入 PDCCH监听集的一个或多个组成载波; 特别地, 新激活的组成载波可以为一个扩展 CC ( Extension CC )或者 CC分 段( CC segment ) , 所述扩展 CC或者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道, 不能进行自行调度而只能依附于其它具有 PDCCH 信道的 CC控制而进行调度使用的 CC, 即需要在所述其它 CC上获取所述扩 展 CC的调度信息, 则 eNB可以在组成载波激活命令中进一步指示调度该扩 展 CC的组成载波。 所述调度该扩展 CC的组成载波, 可以是当前 PDCCH监 听集内的组成载波也可以是组成载波激活命令中指示的需要加入 PDCCH监 听集中的组成载波。
图 7a为本发明实施例提供的另一种组成载波管理方法的示意图, 所述方 法包括:
S71a: 向用户设备发送激活一个或多个组成载波的指示消息;
S72a: 在当前物理下行控制信道监听集内组成载波上发送所述一个或多 个组成载波的调度信息, 或者
在所述一个或多个组成载波中的每个组成载波上发送该组成载波自身的 调度信息;
S73a: 向用户设备发送物理下行控制信道监听集更新命令, 以指示用户 设备对物理下行控制信道监听集进行更新。
本实施例在指示激活组成载波后,可在当前 PDCCH监听集内的 CC上发 送新激活 CC 的调度信息, 并在后续通过 PDCCH监听集更新命令实现对 PDCCH监听集的更新, 例如, 当前 PDCCH监听集内包括组成载波 A, 基站 为用户设备新激活了组成载波 B, 则基站可在组成载波 A上发送组成载波 B 的调度信息, 并在调度结束后通过信令更新 PDCCH监听集。如果所述一个或 多个组成载波中有一个或多个扩展组成载波或者组成载波分段, 则在指定的 组成载波上发送所述一个或多个扩展组成载波或者载波分段的调度信息。 本 实施例还存在另一种实现方式,在一个激活的非扩展 CC上发送该 CC的调度 信息, 而对于扩展 CC, 可在指定的 CC上发送该扩展 CC的调度信息, 并在 调度结束后通过信令更新 PDCCH监听集。本实施例所述扩展 CC是用于传送 数据, 而不用于发送调度信息的 CC。 基站可在配置组成载波时向用户设备指 示用于发送所述扩展 CC的调度信息的 CC。 本实施例的基站可在激活 CC并 发送调度信息后, 进一步发送 PDCCH监听集更新指示, 可在为 UE激活 CC 的过程中, 实时维护 UE的 PDCCH监听集, 保证 UE的业务需求, 降低了 CC的激活时延。 eNB可以向 UE指示 eNB将在当前物理下行控制信道监听集 内组成载波上发送所述一个或多个组成载波的调度信息, 还是在所述一个或 多个组成载波中的每个组成载波上发送该组成载波自身的调度信息, 以便 UE 釆用相应的方式接收调度信息。
图 7b为本发明实施例提供的另一种组成载波管理方法的示意图, 所述方 法包括:
S71b: 接收激活一个或多个组成载波的指示消息;
S72b: 在当前物理下行控制信道监听集内组成载波上接收所述一个或多 个组成载波的调度信息, 或者
在所述一个或多个组成中的每个组成载波上接收该组成载波自身的调度 信息;
S73b: 接收物理下行控制信道监听集更新命令, 并根据所述命令的指示 进行物理下行控制信道监听集的更新。
本实施例中 UE可在激活 CC后, 通过监听激活的 CC或当前 PDCCH监 听集内 CC获取新激活 CC的调度信息, 在后续通过接收来自基站的 PDCCH 监听集更新命令进行 PDCCH监听集的维护。如果所述一个或多个组成载波中 有一个或多个扩展组成载波或者组成载波分段, 则在指定的组成载波上接收 所述一个或多个扩展组成载波或者载波分段的调度信息。 本实施例所述扩展 CC是用于传送数据, 而不用于发送调度信息的 CC。 用户设备可在接收基站 的配置信息时,从配置信息中获知指定的用于发送所述扩展 CC的调度信息的 CC, 并在该指定的 CC上监听以获取扩展 CC的调度信息。 本实施例的用户 设备可在收到 CC的调度信息后, 进一步接收 PDCCH监听集更新指示, 实现 对 PDCCH监听集更新实时维护,保证业务需求, 降低了 CC的激活时延。 UE 可以从 eNB接收指示消息以获知 eNB将在当前物理下行控制信道监听集内组 成载波上发送所述一个或多个组成载波的调度信息, 还是在所述一个或多个 组成载波中的每个组成载波上发送该组成载波自身的调度信息,以便 UE釆用 相应的方式接收调度信息。
图 8为本发明实施例提供的另一种组成载波管理方法的简化流程示意图, 所述方法包括:
S81 : 基站向用户设备发送组成载波重配置消息。
可选地, eNB在与 UE间完成 RRC ( Radio Resource Control, 无线资源控 制)连接建立以后,可基于 UE的业务需求或者其它的 QoS( Quality of Service, 业务质量)要求等, 为 UE新配置一个或多个组成载波。 如果新配置的组成载 波为扩展 CC ( Extension CC )或者 CC分段( CC segment ), 所述扩展 CC或 者 CC分段是指自身不能独立工作的 CC, 即自身没有 PDCCH信道, 不能进 行自行调度而只能依附于其它具有 PDCCH信道的 CC控制而进行调度使用的 CC, 即需要在所述其它 CC上获取所述扩展 CC的调度信息, 则 eNB还可为 UE从 PDCCH监听集内或者从正在激活的组成载波内指定一个或多个调度该 扩展 CC的组成载波。所述组成载波重配置消息可以是 RRC消息, MAC( Media Access Control, 媒体访问控制)控制 PDU ( Protocol Data Unit, 协议数据单 元)或者是物理层控制信令。
S82: 基站向用户设备发送组成载波激活命令。
当 eNB为 UE激活一个或多个新的组成载波时, UE可釆用下列方式之一 获取新激活的 CC的调度信息:
方式 1 : 对新激活的 CC可默认使用 la调度方式, 即将一个新激活的 CC 的调度信息在该 CC 自己的 PDCCH信道上发送给 UE, 即 UE把每个新激活 的 CC 都加入到 PDCCH监听集; 如果该新激活的 CC 为扩展的组成载波 ( extension CC ) , 则该扩展的 CC可在指定的调度该扩展 CC的组成载波上进 行调度;
方式 2: 对新激活的 CC可使用 lb方式调度, 即该新激活的 CC由当前 的 PDCCH监听集内的一个或多个 CC进行调度。 进一步地, eNB可以为 UE 指定调度该新激活的 CC的一个或多个组成载波; 方式 3 : eNB可以根据当前已有的 PDSCH监听集和 PDCCH监听集情况, 或者根据 eNB当前的 CC的调度情况和 /或需要新激活的 CC的数量决定当前 新激活的组成载波是 la或 lb方式,如果 eNB决定使用 lb方式调度, 可以进 一步为 UE指定调度该新激活的 CC的一个或多个组成载波。 即 eNB指定当 前 PDCCH监听集的 CC与新激活的 CC的 linkage关系。
S83: 用户设备监听激活的组成载波的调度信息。
与所述方式 1相应的,UE可在一新激活的 CC上监听以获取该新激活 CC 的调度信息, 即将该新激活 CC加入 PDCCH监听集; 如果该新激活的 CC为 扩展的组成载波(extension CC ), 可在指定的组成载波上进行所述监听。 与 方式 2相应的, UE可在当前的 PDCCH监听集内的一个或多个 CC上进行所 述监听, 以获取新激活的 CC的调度信息。
S84: 进一步地, 在 UE连接的过程中, 基站可以继续向用户设备发送专 用的物理下行控制信道监听集更新命令,指示 UE对物理下行控制信道监听集 进行更新, 该步骤为可选步骤。 eNB可使用 RRC消息、 MAC控制 PDU或者 物理层信令指示 UE进行 PDCCH监听集更新, 即指示 UE对 PDCCH监听集 内的 CC的增加、 移除或者重配置。
本实施例中基站为 UE配置 CC, 并激活一个或多个 CC, UE通过将新激 活的 CC加入 PDCCH监听集, 通过监听一新激活的 CC来获取该新激活 CC 的调度信息, 随后 eNB可指示 UE进行物理下行控制信道监听集的更新, UE 在更新物理下行控制信道监听集后, 可实现后续对 PDCCH的监听。
与方法实施例相应地, 本实施例提供了设备实施例以执行所述方法, 可 以理解, 所述设备可以通过硬件、 软件或二者结合的方式来实现。
