Description

一种信息传输的方法、 系统和设备 本申请要求在 2012年 12月 28日提交中国专利局、 申请号为 201210587708.2、发明名称为
"一种信息传输的方法、 系统和设备"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
本发明涉及无线通信技术领域, 特别涉及一种信息传输的方法、 系统和 设备。 背景技术
随着技术的演进和数据业务的增加, 小小区 (small cell)的概念提出并受到 高度关注。 small cell通常具有较小的覆盖范围和较低的发射功率,通过将 small cell部署在距离用户更近的位置, 例如室内和热点区域, 可以提升用户的数据 速率。
根据目前的研究, small cell的类型主要分为三种,仅具有独立属性的 small cell, 仅具有非独立属性的 small cell 和具有独立和非独立双重属性的 small cell, 图 1A和图 1B分别给出了 small cell非独立和独立工作的示意。
包含本地演进基站(Local eNB )和宏演进基站(Macro eNB ) 的异构网 络部署场景如图 1C所示。 其中 Macro基站提供宏覆盖, Local eNB在宏覆盖 范围内提供热点覆盖。 图 1C异构网络部署场景对于上图所示的网络架构, 如 果按照现有机制, 用户设备 ( User Equipment, UE )在 Macro cell覆盖范围内 移动时, 可能不断执行 Macro cell 与 Local cell之间的切换操作。 为了避免频 繁切换导致信息传输中断, 一种方式就是让 UE可以同时聚合 Local eNB和 Macro eNB的资源, 但是无线资源控制 ( Radio Resource Control, RRC )连接 维持在 Macro eNB下, Local资源仅用于信息传输,即控制面用户面分离技术, 也称为 7 载分离。
在增强长期演进( LTE- Advanced , LTE-A ) 系统中, 系统的峰值速率比 长期演进(Long Term Evolution, LTE ) 系统有巨大的提高, 要求达到下行 lGbps, 上行 500Mbps。 因此, LTE-A系统需要扩展用户设备可用带宽, 即将 同一个演进基站 (evolved Node B, eNB ) 下的多个连续或不连续的载波聚合 在一起, 同时为 UE服务, 以提供所需的速率, 如图 1D所示。 这些聚合在一 起的载波又称为成员载波(Component Carrier, CC )。 每个小区都可以是一个 成员载波。 为了保证后向兼容性, 每个载波最大不超过 20MHz。
在载波聚合中, 其中一个成员载波被配置为主载波 (Pcell或 PCC), 用户 设备在主载波上接收物理下行控制信道 ( Physical Downlink Control Channel, PDCCH )公共搜索空间(Common Search space, CSS)和搜索空间 (UE specific search space , UESS) , 其中公共搜索空间用于发送调度公共控制信令的 PDCCH, 例如广播、 寻呼等, UE搜索空间用于发送针对用户的调度信令等。 除主载波以外的其他成员载波都成为辅载波(Scell或 SCC ),用户设备在辅载 波上仅接收 PDCCH UE搜索空间, 不接收 PDCCH公共搜索空间。 并且, 用 户设备在 Pcell和 Scell上盲检 PDCCH UE搜索空间的盲检次数是相同的。
根据频谱的使用情况, small cell将主要使用高频段 (例如 3.5GHz或以上), 而 Macro cell主要使用较低频段 (例如 2GHz或以下)。 因此, 承载分离工作方 式与载波聚合可以结合使用,用户设备的控制面连接维持在较低频段由 Macro 服务, 用户面连接则维持在较高频段由 small cell服务。 这种方案中, 通常将 与 Macro连接的成员载波( Component Carrier, CC )作为 Pcell, 用户设备在 该 CC上主要接收系统广播、 寻呼、 RRC信令等; 同时网络将与 small cell连 接的 CC作为 Scell, 用户设备在该 CC上仅接收用户面控制信令、 数据等。
在载波聚合与 C/U分离相结合的方案中, Pcell上仅传输控制面信令, 些 高层控制信令并不总是发送的, 因此 Pcell上总的数据量比较低; Scell用于传 输用户面控制信令、 数据等。 由于 small cell基站距离用户设备更近, 信号质 量更好, 对于高吞吐量需求的用户, 将大量的信息传输都在 Scell上进行, 因 此 Scell上总的数据量很高。 而目前用户设备需要进行大量无意义的 Pcell监 听, 从而造成不必要的能量消耗, 并且降低了 Scell上的调度灵活性。 综上所述, 目前用户设备需要进行大量无意义的 Pcell监听, 从而造成不 必要的能量消耗, 并且降低了 Scell上的调度灵活性。 发明内容
本发明提供一种信息传输的方法, 用以解决现有技术中存在的用户设备 需要进行大量无意义的 Pcell监听, 从而造成不必要的能量消耗, 并且降低了 Scell上的调度灵活性的问题。

用户设备, 用于确定网络侧设备配置的目标小区上的监听信息根据所述 监听信息, 进行监听, 并接收所述网络侧设备发送的下行信号。
本发明实施例由于网络侧设备根据根据包括监听位置和 /或监听配置信息 的监听信息, 向所述用户设备发送下行信号, 从而降低了用户设备进行无意 义的 Pcell监听的次数, 降低了能量消耗, 提高了 Scell上的调度灵活性。 附图说明

由于大量无意义的 Pcell监听, 而实际上 Pcell仅有很少量的数据发送, 造成不必要的用户设备能量消耗,并且由于用户设备总的 PDCCH盲检能力受 限的情况下, 大量无意义的 Pcell PDCCH盲检, 间接制约了 Scell上可用的 PDCCH盲检机会的提升, 从而制约了 Scell上调度灵活性。 而本发明实施例 由于网络侧设备根据根据包括监听位置和 /或监听配置信息的监听信息, 向用 户设备发送下行信号, 从而降低了用户设备进行无意义的 Pcell监听的次数, 降低了能量消耗, 提高了 Scell上的调度灵活性。
其中,本发明实施例的方案可以应用于载波聚合结合 C/U分离的场景中, 还可以应用于其他载波聚合的场景中。
本发明实施例的方案可以应用于载波聚合中的 Pcell, 即载波聚合结合 C/U分离场景中 UE与 Macro基站通信的载波, 也可以应用于 Scell或其他载 波上。
下面结合说明书附图对本发明实施例作进一步详细描述。
在下面的说明过程中, 先从网络侧和用户设备侧的配合实施进行说明, 最后分别从网络侧与用户设备侧的实施进行说明, 但这并不意味着二者必须 配合实施, 实际上, 当网络侧与用户设备侧分开实施时, 也解决了分别在网 络侧、 用户设备侧所存在的问题, 只是二者结合使用时, 会获得更好的技术 效果。
如图 2所示, 本发明实施例信息传输的系统包括: 网络侧设备 10和用户 设备 20。
网络侧设备 10, 用于确定为用户设备配置的目标小区上的监听信息, 其 中监听信息包括监听位置和 /或监听配置信息, 根据监听信息, 向用户设备发 送下行信号;
用户设备 20, 用于确定网络侧设备配置的目标小区上的监听信息, 根据 监听信息, 进行监听, 并接收网络侧设备发送的下行信号。
较佳地, 网络侧设备 10发送的下行信号可以是下列下行信号中的一种:
PDCCH信号、 增强物理下行控制信道(EPDCCH )信号和物理下行共享 信道( Physical Downlink Shared Channel, PDSCH )信号。
较佳地, 网络侧设备 10可以通过高层信令为用户设备 20配置目标小区 上的监听信息;
相应的, 用户设备 20通过高层信令接收网络侧设备 10配置的目标小区 上的监听信息。
下面对监听信息包括不同内容的处理方式分别进行说明。
方式一、 监听信息包括监听位置。
这里的监听位置表示的试需要进行监听的子帧。
在实施中,可以将子帧标识作为监听位置,比如需要监听的子帧是子帧 6, 则可以将 6作为监听位置; 还可以将比特位图 (bitmap )作为监听位置, 其中 bitmap 中的一个比特位对应一个子帧, 比特位的取值标识是否是需要进行监 听的子帧, 比如 0表示不是, 1表示是, 子帧 6和子帧 9是需要进行监听的子 帧, 则 bitmap为 000001001。
需要说明的是, 上面两种监听位置表达方式只是举例说明, 任何能够表 征需要进行监听的子帧的信息都可以作为监听位置。
其中, 网络侧设备 10先根据监听位置, 确定用户设备在目标小区的特定 子帧集合; 然后在确定的特定子帧集合中的至少一个子帧上, 向用户设备 20 发送下行信号;
相应的, 用户设备 20根据监听位置, 确定在目标小区的特定子帧集合, 并在特定子帧集合中的至少一个子帧上, 进行监听。
对于方式一, 网络侧设备 10对载波聚合的用户设备 20进行配置, 使其 在一个 Cell (或 CC)上仅在一部分子帧监听和接收数据。
网络侧设备 10可以通过高层信令配置,告知用户设备 20在 Pcell上 (或每 个 Cell)上需要的特定子帧集合,用户设备 20在相应的 cell中仅在被通知的特 定子帧集合内监听和接收下行数据。
在配置的需要的特定子帧集合中, 用户设备 20监听所有的 PDCCH并根 据调度情况接收 PDSCH; 在该特定子帧集合外的其他子帧中, 用户设备 20 不接收任何下行信号。
当目标小区为 PCell时,需要保证用户设备 20在 Pcell上能够正确接收到 网络侧设备发送的公共信息(比如系统信息、 寻呼消息等), 因此目标小区的 特定子帧集合至少包括子帧 0和子帧 5。 当目标小区为 SCell时,如果用户设备 20需要在某个 Scell监听公共信息 (比如系统信息、 寻呼消息等), 则目标小区的特定子帧集合中包括的子帧能 够使用户设备正确接收网络侧设备发送的公共信息。
在实施中, 网络侧设备 10在除特定子帧集合之外的子帧上不发送下行信 号; 相应的, 用户设备 20在需要的特定子帧集合之外的子帧上不接收下行信 号。 或者
网络侧设备 10在除特定子帧集合之外的子帧上发送 PDCCH CSS信号; 相应的, 用户设备 20 在确定的特定子帧集合之外的子帧上不盲检 PDCCH UESS或 EPDCCH UESS, 仅盲检 PDCCH CSS, 并仅接收由 PDCCH CSS中 DCI调度的数据。
由于用户设备 20在目标小区的特定子帧集合之外的子帧中不进行监听或 者仅盲检 PDCCH CSS, 所以一种较佳地方式是:
用户设备 20在目标小区的特定子帧集合之外的子帧中, 将盲检能力用于 对其他小区的 PDCCH盲检。
其中, 监听包括对控制信道 PDCCH或 EPDCCH的接收, 也包括对数据 信道 PDSCH的接收, 在 LTE系统中用户设备通过盲检的方式接收控制信道 PDCCH或 EPDCCH。
较佳地, 用户设备 20 可以将部分或全部盲检能力用于对其他小区的 PDCCH盲检。
较佳地, 这里的部分盲检能力为盲检专属的 PDCCH UESS或 EPDCCH UESS的能力。
这里的全部盲检能力包括盲检专属的 PDCCH UESS或 EPDCCH UESS的 能力, 还包括盲检其他信号的能力, 比如盲检 PDCCH CSS 的能力, 盲检 PDSCH的能力等。
下面列举一个例子对方式一进行说明。
例如, 网络侧设备 10可以通过 RRC信令以 bitmap方式告知用户设备 20 在一定时间周期 (例如每个无线帧)内, 哪些子帧是必须监听。 如下表 1所示, 网络侧设备 10配置用户设备 20在 Pcell上每个无线帧的子帧 {0,4,5,9}中必须 监听。 而在该集合之外的其他子帧 {1,2,3,6,7,8}中, 用户设备 20不接收任何下 行信号, 或者仅盲检 PDCCH CSS及其调度的数据。

表 1 : 使用 bitmap方式配置 Pcell上需要监听的子帧 进一步的, 在某一 cell上不需要监听的子帧中, 用户设备 20的 PDCCH 盲检能力可分配至其他需要监听的 cell上。 以表 1例, 当用户设备 20聚合了 两个载波时, 用户设备 20仅需要在特定子帧集合 {0,4,5,9}中完整监听 Pcell, 在该特定子帧集合内(称为子帧集合 1), PDCCH盲检在 Pcell和 Scell的分配 与现有技术相同, 具体可以参见 3GPP TS 36.213 在子帧集合 1外的其他子帧 中 (称为子帧集合 2), 由于用户设备 20不需要监听 Pcell, 空出的 PDCCH盲 检能力可以分配给 Scell, 具体的 PDCCH盲检能力重新分配又可以有如下两 种方式:
1、 将 Pcell上某一子帧的所有 PDCCH盲检能力都分配给 Scell。 表 2和 表 3分别给出了该种方式下在上述子帧集合 2内 Pcell和 Scell上的 PDCCH盲 检配置分配。
2、 将 Pcell上某一子帧的专属的 PDCCH或 EPDCCH盲检能力分配给 Scell„ 表 4和 5分别给出了该种方式下在上述子帧集合 2内 Pcell和 Scell上 的 PDCCH盲检配置分配。

方式二、 监听信息包括监听配置信息。 这里的监听配置信息表示的是在每个子帧上需要盲检的次数。 在实施中, 监听配置信息可以是:
为用户设备在一个子帧中对不同目标小区进行盲检的次数比例, 由于用 户设备在一个子帧上总的盲检次数是确定的, 所以用户设备 20可以根据次数 比例确定在不同目标小区的盲检次数; 或
为用户设备在每个目标小区上进行盲检的总次数, 其中多个目标小区总 的盲检的次数不大于用户设备能够进行盲检的最大次数, 以 2CC为例, 用户 设备 20配置 Pcell上进行专属的 PDCCH或 EPDCCH盲检的次数为 6, Scell 上进行专属的 PDCCH或 EPDCCH盲检的次数为 26, 如表 6和表 7所示; 或 为用户设备在每个目标小区上每个聚合等级进行盲检的次数, 其中多个 目标小区总的盲检的次数不大于用户设备能够进行盲检的最大次数, 假设每 个成员载波中用户设备需要盲检多种聚合等级 { 1 ,2,4,8 } ,上面为用户设备在每 个目标小区上进行盲检的总次数是配置成员载波的盲检次数即不区分聚合等 级, 仅告知总的次数; 这里是分别告知每种聚合等级分别的盲检次数; 或
为用户设备在不同目标小区进行盲检的比例划分方式, 例如等比例划分, 或者非等比例划分等。 以 2CC为例, 等比例划分方式即与现有技术相似, 具 体可以参见 3GPP TS 36.213议, 在此不再赘述; 非等比划分方式与表 6和表 7相似。

需要说明的是, 上面几种监听配置信息的内容只是举例说明, 任何能够 表征在每个子帧上需要盲检的次数都可以作为监听配置信息。
其中, 网络侧设备 10 根据监听配置信息, 向用户设备 20 发送专属的 PDCCH或 EPDCCH;
相应的,用户设备 20根据监听配置信息,盲检 PDCCH UESS或 EPDCCH UESS。
其中, 网络侧设备 10在确定用户设备 20在子帧上盲检的次数后, 具体 向用户设备 20发送专属的 PDCCH或 EPDCCH的方式可以参见 3GPP TS 36.211和 3GPP TS36.213协议, 在此不再赘述。
方式三、 监听信息包括监听位置和监听配置信息。
方式三是方式一和方式二的结合, 即方式二中对于多个 CC的 PDCCH盲 检配置可以仅应用于一部分子帧中, 这类子帧通过方式一的方法通知给用户 设备 20。 用户设备 20在部分子帧上, 按照现有技术规定监听 Pcell和 Scell 的 PDCCH, 在另一部分子帧上则按照配置的 PDCCH盲检配置划分方式监听 Pcell和 Scell。
其中, 方式三的监听位置与方式一的监听位置相同, 方式三的监听配置 信息与方式二的监听配置信息相同, 在此不再重复介绍。
在实施中, 针对方式三还有两种处理方式:
1、 网络侧设备 10根据监听位置, 确定用户设备在目标小区的特定子帧 集合, 并根据监听配置信息,在确定的特定子帧集合中发送专属的 PDCCH或 EPDCCH;
相应的, 用户设备 20根据监听位置, 确定目标小区的特定子帧集合, 并 根据监听配置信息,在确定的特定子帧集合中盲检 PDCCH UESS或 EPDCCH UESS。
在配置的需要的特定子帧集合中, 用户设备 20监听所有的 PDCCH并根 据调度情况接收 PDSCH; 在该特定子帧集合外的其他子帧中, 用户设备 20 不接收任何下行信号。
当目标小区为 PCell时,需要保证用户设备 20在 Pcell上能够正确接收到 网络侧设备发送的公共信息(比如系统信息、 寻呼消息等), 因此目标小区的 特定子帧集合至少包括子帧 0和子帧 5。
当目标小区为 SCell时,如果用户设备 20需要在某个 Scell监听公共信息 (比如系统信息、 寻呼消息等), 则目标小区的特定子帧集合中包括的子帧能 够使用户设备正确接收网络侧设备发送的公共信息。
在实施中, 网络侧设备 10在除特定子帧集合之外的子帧上不发送下行信 号; 相应的, 用户设备 20在需要的特定子帧集合之外的子帧上不接收下行信 号。 或者
网络侧设备 10在除特定子帧集合之外的子帧上发送 PDCCH CSS信号; 相应的, 用户设备 20 在确定的特定子帧集合之外的子帧上不盲检 PDCCH UESS或 EPDCCH UESS, 仅盲检 PDCCH CSS, 并仅接收由 PDCCH CSS中 DCI调度的数据。
由于用户设备 20在目标小区的特定子帧集合之外的子帧中不进行监听或 者仅盲检 PDCCH CSS, 所以一种较佳地方式是:
用户设备 20在目标小区的特定子帧集合之外的子帧中, 将盲检能力用于 对其他小区的 PDCCH盲检。
较佳地, 用户设备 20 可以将部分或全部盲检能力用于对其他小区的 PDCCH盲检。
较佳地,这里的部分盲检能力为盲检 PDCCH UESS或 EPDCCH UESS的 能力。

下面对监听信息包括不同内容的处理方式分别进行说明。
方式一、 监听信息包括监听位置。
这里的监听位置表示的试需要进行监听的子帧。
在实施中,可以将子帧标识作为监听位置,比如需要监听的子帧是子帧 6, 则可以将 6作为监听位置; 还可以将 bitmap作为监听位置, 其中 bitmap中的 一个比特位对应一个子帧, 比特位的取值标识是否是需要进行监听的子帧, 比如 0表示不是, 1表示是,子帧 6和子帧 9是需要进行监听的子帧,则 bitmap 为 000001001。
需要说明的是, 上面两种监听位置表达方式只是举例说明, 任何能够表 征需要进行监听的子帧的信息都可以作为监听位置。
其中, 网络侧设备先根据监听位置, 确定用户设备在目标小区的特定子 帧集合; 然后在确定的特定子帧集合中的至少一个子帧上, 向用户设备发送 下行信号。

为用户设备在每个目标小区上每个聚合等级进行盲检的次数, 其中多个 目标小区总的盲检的次数不大于用户设备能够进行盲检的最大次数; 或
为用户设备在不同目标小区进行盲检的比例划分方式。
其中, 网络侧设备根据监听配置信息, 向用户设备发送专属的 PDCCH或

网络侧设备在确定用户设备在子帧上盲检的次数后, 具体向用户设备发 送专属的 PDCCH或 EPDCCH的方式可以参见 3GPP TS 36.211和 TS36.213 协议, 在此不再赘述。
方式三、 监听信息包括监听位置和监听配置信息。
方式三是方式一和方式二的结合, 即方式二中对于多个 CC的 PDCCH盲 检配置可以仅应用于一部分子帧中, 这类子帧通过方式一的方法通知给用户 设备。 用户设备在部分子帧上, 按照现有技术规定监听 Pcell 和 Scell 的 PDCCH, 在另一部分子帧上则按照配置的 PDCCH 盲检配置划分方式监听 Pcell和 Scell。
其中, 方式三的监听位置与方式一的监听位置相同, 方式三的监听配置 信息与方式二的监听配置信息相同, 在此不再重复介绍。
在实施中, 针对方式三还有两种处理方式:
1、网络侧设备根据监听位置,确定用户设备在目标小区的特定子帧集合, 并根据监听配置信息, 在确定的特定子帧集合中发送专属的 PDCCH 或 EPDCCH;
当目标小区为 PCell时, 需要保证用户设备在 Pcell上能够正确接收到网 络侧设备发送的公共信息(比如系统信息、 寻呼消息等), 因此目标小区的特 定子帧集合至少包括子帧 0和子帧 5。
当目标小区为 SCell时,如果用户设备需要在某个 Scell监听公共信息(比 如系统信息、 寻呼消息等), 则目标小区的特定子帧集合中包括的子帧能够使 用户设备正确接收网络侧设备发送的公共信息。
在实施中, 网络侧设备在除特定子帧集合之外的子帧上不发送下行信号; 网络侧设备在除特定子帧集合之外的子帧上发送 PDCCH CSS信号。
2、网络侧设备根据监听位置,确定用户设备在目标小区的特定子帧集合, 并根据监听配置信息, 在特定子帧集合之外的子帧中向用户设备发送用户设 备专属的 PDCCH或 EPDCCH。
基于同一发明构思, 本发明实施例中还提供了一种用户设备接收信息的 方法, 由于该方法对应的设备是本发明实施例信息传输的系统中用户设备, 并且该方法解决问题的原理与该设备相似, 因此该方法的实施可以参见设备 的实施, 重复之处不再赘述。

步骤 602、 用户设备根据监听信息, 进行监听, 并接收网络侧设备发送的 下行信号。
较佳地, 用户设备通过高层信令接收网络侧设备配置的目标小区上的监 听信息。
下面对监听信息包括不同内容的处理方式分别进行说明。
方式一、 监听信息包括监听位置。
用户设备根据监听位置, 确定在目标小区的特定子帧集合, 并在特定子 帧集合中的至少一个子帧上, 进行监听。
在配置的需要的特定子帧集合中 ,用户设备监听所有的 PDCCH并根据调 度情况接收 PDSCH; 在该特定子帧集合外的其他子帧中, 用户设备不接收任 何下行信号。
当目标小区为 PCell时, 需要保证用户设备在 Pcell上能够正确接收到网 络侧设备发送的公共信息(比如系统信息、 寻呼消息等), 因此目标小区的特 定子帧集合至少包括子帧 0和子帧 5。
当目标小区为 SCell时,如果用户设备需要在某个 Scell监听公共信息(比 如系统信息、 寻呼消息等), 则目标小区的特定子帧集合中包括的子帧能够使 用户设备正确接收网络侧设备发送的公共信息。
在实施中, 用户设备在需要的特定子帧集合之外的子帧上不接收下行信 号。 或者用户设备在确定的特定子帧集合之外的子帧上不盲检 PDCCH UESS 或 EPDCCH UESS, 仅盲检 PDCCH CSS, 并仅接收由 PDCCH CSS中 DCI调 度的数据。
由于用户设备在目标小区的特定子帧集合之外的子帧中不进行监听或者 仅盲检 PDCCH CSS, 所以一种较佳地方式是:
用户设备在目标小区的特定子帧集合之外的子帧中, 将盲检能力用于对 其他小区的 PDCCH盲检。
较佳地, 用户设备可以将部分或全部盲检能力用于对其他小区的 PDCCH 盲检。
较佳地,这里的部分盲检能力为盲检专属的 PDCCH或 EPDCCH的能力。 方式二、 监听信息包括监听配置信息。
为用户设备在一个子帧中对不同目标小区进行盲检的次数比例; 或 为用户设备在每个目标小区上进行盲检的总次数, 其中多个目标小区总 的盲检的次数不大于用户设备能够进行盲检的最大次数; 或
为用户设备在每个目标小区上每个聚合等级进行盲检的次数, 其中多个 目标小区总的盲检的次数不大于用户设备能够进行盲检的最大次数; 或
为用户设备在不同目标小区进行盲检的比例划分方式。
其中, 用户设备根据监听配置信息, 盲检 PDCCH UESS 或 EPDCCH
UESS。 方式三、 监听信息包括监听位置和监听配置信息。
方式三是方式一和方式二的结合, 即方式二中对于多个 CC的 PDCCH盲 检配置可以仅应用于一部分子帧中, 这类子帧通过方式一的方法通知给用户 设备。 用户设备在部分子帧上, 按照现有技术规定监听 Pcell 和 Scell 的 PDCCH, 在另一部分子帧上则按照配置的 PDCCH 盲检配置划分方式监听 Pcell和 Scell。
其中, 方式三的监听位置与方式一的监听位置相同, 方式三的监听配置 信息与方式二的监听配置信息相同, 在此不再重复介绍。
在实施中, 针对方式三还有两种处理方式:
1、 用户设备根据监听位置, 确定目标小区的特定子帧集合, 并根据监听 配置信息, 在确定的特定子帧集合中盲检 PDCCH UESS或 EPDCCH UESS。
在配置的需要的特定子帧集合中 ,用户设备监听所有的 PDCCH并根据调 度情况接收 PDSCH; 在该特定子帧集合外的其他子帧中, 用户设备 20不接 收任何下行信号。
当目标小区为 PCell时, 需要保证用户设备在 Pcell上能够正确接收到网 络侧设备发送的公共信息(比如系统信息、 寻呼消息等), 因此目标小区的特 定子帧集合至少包括子帧 0和子帧 5。
当目标小区为 SCell时,如果用户设备需要在某个 Scell监听公共信息(比 如系统信息、 寻呼消息等), 则目标小区的特定子帧集合中包括的子帧能够使 用户设备正确接收网络侧设备发送的公共信息。
在实施中, 用户设备在确定的特定子帧集合之外的子帧上不盲检 PDCCH UESS或 EPDCCH UESS, 仅盲检 PDCCH CSS, 并仅接收由 PDCCH CSS中 DCI调度的数据。
由于用户设备在目标小区的特定子帧集合之外的子帧中不进行监听或者 仅盲检 PDCCH CSS, 所以一种较佳地方式是:
用户设备在目标小区的特定子帧集合之外的子帧中, 将盲检能力用于对 其他小区的 PDCCH盲检。 较佳地, 用户设备可以将部分或全部盲检能力用于对其他小区的 PDCCH 盲检。
较佳地,这里的部分盲检能力为盲检 PDCCH UESS或 EPDCCH UESS的 能力。
