Description

TDD上下行配比的获取方法及装置 技术领域
本发明涉及通信系统领域, 特别涉及一种 TDD上下行配比的获取方法 及装置。 背景技术
在 LTE ( Long Time Evolution, 长期演进) 系统中支持两种帧结构: FDD ( Frequency Division Duplexing, 频分双工) 帧结构及 TDD ( Time Division Duplexing, 时分双工) 帧结构。 其中, TDD帧结构支持七种不 同的上下行配比, 网络侧节点根据 UE ( User Equipment, 用户设备) 与 各个服务小区之间进行通信的业务量, 对 UE 的各个服务小区对应的 TDD 上下行配比进行配置。 通常, 网络侧节点通过系统广播消息或者专用 RRC ( Radio Resource Control, 无线资源控制) 消息向 UE发送各个服务小 区对应的 TDD上下行配比。
目前, 网络侧节点通过动态改变各个服务小区的 TDD上下行配比, 从 而使得 UE的各个服务小区可以更好的适应不同业务量的变化。 具体地, UE按照网络侧节点发送的物理下行控制信令中携带的服务小区的 TDD上 下行配比命令, 为服务小区配置对应的 TDD上下行配比。
然而, UE接收的物理下行控制信令中仅携带一个服务小区的 TDD上 下行配比命令, 从而导致 UE为各个服务小区配置对应的 TDD上下行比例 时, 需要接收多个物理下行控制信令, 进而导致系统信令开销较大。

其中, 物理下行控制信令中包括至少一个 TDD上下行配比命令, 至少 一个 TDD上下行配比命令中的每个 TDD上下行配比命令分别携带有对应的 TDD上下行配比。 在本发明实施例中, TDD无线帧支持 7种不同的 TDD上下行 配比, 具体如下表所示:
Figure imgf000014_0001
可选地, 步骤 1 01可以为, UE按照预设周期接收网络侧节点发送的物 理下行控制信令。其中,预设周期可以由网絡侧节点预先进行配置,例如, 预设周期可以为 1 0毫秒、 2 0毫秒、 4 0毫秒等。 在本发明实施例中, UE按照 预设周期接收网络侧节点发送的物理下行控制信令,能够使得 UE实时地为 各个服务小区应用对应的 TDD上下行配比, 从而可以实现 UE的各个服务小 区可以更好地适应不同业务量的变化。
对于本发明实施例, 通过在物理下行物理信令中携带多个 T D D上下行 配比命令, 能够减少网络侧节点发送物理下行控制信令的次数, 从而可以 降低系统信令开销。 例如图 4所示, 一个物理下行控制信令中包括 5个 TDD 上下行配比命令。
102、 UE接收网络侧节点发送的配置消息。
其中,配置消息携带有 UE的各个服务小区中的每个服务小区与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系。 在本发明实 施例中, UE的各个服务小区中的每个服务小区与对应的 TDD上下行配比命 令在物理下行控制信令中位置的对应关系,用于指示 UE在接收到的物理下 行控制信令中, 为各个服务小区获取对应的 TDD上下行配比。
对于本发明实施例, 配置消息可以为系统广播消息或者专用 RRC ( Radio Resource Control, 无线资源控制) 消息, 也可以为新设计的消 息, 或者在现有消息中新增加的 IE ( Information Element, 信息元), 本 发明实施例不作限定。
对于本发明实施例,通过 UE的各个服务小区中的每个服务小区与对应 的 TDD上下行配比命令在物理下行控制信令中位置的对应关系, 能够实现 UE正确地为各个 良务小区分别应用对应的 TDD上下行配比。
103、 UE根据 UE的各个服务小区中的每个服务小区与对应的 TDD上下行 配比命令在物理下行控制信令中位置的对应关系, 从至少一个 TDD上下行 配比命令中, 获取 UE的各个服务小区分别对应的 TDD上下行配比。
对于本发明实施例, 网络侧节点为 UE配置的上行资源包括: 上行的 SR ( schedule reques t调度请求 ) 资源、 CQ I ( channel quality indicator 信道廣量指示) 4艮告资源, CSI ( Channel Status Information, 信道状 态信息 ) 资源, SRS ( sounding reference s igna 1监听参考信号 ) 资源, PRACH ( Physical Random Access Cha騰 1,物理随机接入信道) 资源等。 具体地, UE可以按照预设周期上报 SR资源、 CQI报告资源、 CSI资源、 PRACH 资源、 SRS资源等上行资源。 例如, 预设周期可以为: 1毫秒、 5毫秒、 10 毫秒、 20毫秒等。 在本发明实施例中, 可以通过资源对应的周期及偏移量 确定资源在 TDD上下行配比中的位置。 例如, 以 1 0毫秒为周期发送无线帧, 若 SR资源的周期为 1 0毫秒、 偏移量为 2毫秒, 则表示在每个无线帧的子帧 2 上为 UE配置该 SR资源, 即 UE可以在每个无线帧的子帧 2上使用 SR资源发送 SR。 再例如, 以 1 0毫秒为周期发送无线帧, 若 SR资源的周期为 2 0毫秒、 偏 移量为 3毫秒, 则表示在偶数无线帧的子帧 3上为 UE配置该 SR资源, 即 UE 可以在偶数无线帧的子帧 3上使用 SR资源发送 SR。 其中, 偶数无线帧的子 帧 3包括: 0号无线帧的子帧 3、 2号无线帧的子帧 3、 4号无线帧的子帧 3等。
对于本发明实施例, 由于 TDD上下行配比可以进行动态改变, 因此存 在子帧在部分无线帧中被指示为上行子帧,在部分无线帧中被指示为下行 子帧的情况。 此时, 存在为 UE配置的上行资源的位置与子帧方向发生冲突 的情况, 当 UE在上行资源发送信号, 并且该资源的子帧方向为下行时, UE 发送的信号会对其它 UE造成干扰; 同时, 由于此时 UE发送的信号为无用信 号, 因此会造成 UE发射功率的浪费。
可选地, 本发明实施例提供了一种上行资源的配置方法, 具体包括: 网络侧节点为 UE配置的上行资源, 在 UE的下行参考配比中的上行子帧和 I 或特殊子帧上。 其中, UE可以通过本发明实施例提供的方式动态改变 TDD 上下行配比。
其中, 当 UE仅对应一个服务小区时, UE在该服务小区的下行参考配比 为 UE的下行参考配比。 当 UE对应多个服务小区时, UE的主服务小区的下行 参考配比或者已经配置上述上行资源的服务小区为 UE的下行参考配比。
例如下表中所示,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集 合 {TDD上下行配比 0 , TDD上下行配比 1 }中进行动态改变, UE的下行参考配 比为 TDD上下行配比 2 , 则按照本发明实施例提供的方法, 只有上行子帧 2、 上行子帧 7及特殊子帧 1、 特殊子帧 6可以配置上述上行资源。
TDD上下行 转换间 子帧序号
配比序号 隔周期 0 1 2 3 4 5 6 7 8 9 0 5ms D S u u u D S u u u
1 5ms D S u u D D S u u D
2 5ms D s u D D D s u D D 其中, TDD动态配比集合可以是现有的 7种 TDD上下行配比的集合, 也 可以是新的 TDD上下行配比的集合, 本发明实施例不做限定。 在本发明实 施例中 , TDD动态配比集合可以是固定的或配置的 TDD上下行配比的集合, 也可以是一段时间内 UE使用的 TDD上下行配比的集合。
对于本发明实施例,由于 UE的下行参考配比为各个 TDD上下行配比中, 该 U E的上行子帧和特殊子帧数量最少的配比,该配比中的上行子帧和特殊 子帧不会被动态配置下行子帧,因此通过将上述上行资源配置在该 UE的下 行参考配比中的上行子帧或者特殊子帧上,能够避免由于子帧方向改变所 造成的 UE之间互相干扰。
可替换地, 本发明实施例提供了另一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上行资源, 在 UE的 TDD动态配比集合中, 上行 子帧及特殊子帧数量最少的 TDD上下行配比所对应的上行子帧和 /或特殊 子帧上。
例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 其中, TDD下行配比 1中的上 行子帧及特殊子帧最少, 则按照本发明实施例提供的方法, 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8及特殊子帧 1、 特殊子帧 6可以配置上 述上行资源。
对于本发明实施例, 该 UE的 TDD动态配比集合中的上行子帧或者特殊 子帧数量最少的 TDD上下行配比中, 上行子帧和特殊子帧不会被动态配置 为下行子帧,因此将上述上行资源配置在该 UE的下行参考配比中的上行子 帧和 /或特殊子帧上, 能够避免避免由于子帧方向改变所造成的 UE之间互 相干扰, 同时可以增加可以配置上行资源的子帧数量。 进一步地, 本发明实施例提供了又一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上述上行资源的子帧位置必须为上行子帧和 / 或特殊子帧,对于其它没有配置上述上行资源的子帧位置的方向可以改变 为下行。
或者,网络侧节点为 UE配置的上述上行资源的子帧位置限制在物理下 行控制信令指示该子帧为上行子帧或者特殊子帧的子帧位置。
例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 上行资源 SR资源的周期为 2 0 毫秒、 偏移量为 9毫秒, 则为偶数无线帧的子帧 9配置 S R资源, 即偶数无线 帧的子帧 9的方向不可改变为下行; 同时奇数无线帧的子帧 9没有配置 S R 资源, 即奇数无线帧的子帧 9的方向仍然可以改变为下行。 按照本发明实 施例提供的方法, 可以配置上述上行资源的子帧可以包括: 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8、 偶数无线帧的子帧 9, 及特殊子帧 1、 特殊子帧 6。
对于本发明实施例,将上述上行资源配置在该 UE的下行参考配比中的 必须为上行子帧和 /或特殊子帧上, 能够避免避免由于子帧方向改变所造 成的 UE之间互相干扰, 同时可以最大限度的利用上行子帧和 /或特殊子帧 配置上行资源。
对于本发明实施例, 在跨站点载波聚合场景下, 各个网絡侧节点可以 分别按照本发明实施例提供的方法, 为各个服务小区分别应用对应的 TDD 上下行配比; 同时, 各个网絡侧节点之间还可以通过交互的方式, 为各个 服务小区分别应用对应的 TDD上下行配比。
具体地, 在跨站点载波聚合场景下, 微基站可以通过 Xn接口, 将各个 服务小区与各个 TDD上下行配比的对应关系及 TDD上下行配比的配置参数 等信息发送给宏基站,以使得宏基站可以根据各个微基站与各个 UE之间进 行通信的业务量, 为各个微基站应用对应的 TDD上下行配比。 同时, 宏基 站也可以根据自身业务量及负载情况等,为微基站应用各个服务小区与各 个 TDD上下行配比的对应关系及 TDD上下行配比的配置参数等信息 ,以使得 各个 i基站可以实时应用服务小区对应的 TDD上下行配比。

对于本发明实施例, 网络侧节点为 UE配置的上行资源包括: 上行的 SR ( schedule reques t调度请求 ) 资源、 CQI ( channel quality indicator 信道质量指示) 4艮告资源, CSI ( Channel Status Information, 信道状 态信息 ) 资源, SRS ( sounding reference s igna 1监听参考信号 ) 资源, PRACH ( Physical Random Access Cha購 1,物理随机接入信道) 资源等。 具体地, UE可以按照预设周期上报 SR资源、 CQI报告资源、 CSI资源、 PRACH 资源、 SRS资源等上行资源。 例如, 预设周期可以为: 1毫秒、 5毫秒、 10 毫秒、 20毫秒等。 在本发明实施例中, 可以通过资源对应的周期及偏移量 确定资源在 TDD上下行配比中的位置。 例如, 以 10毫秒为周期发送无线帧, 若 SR资源的周期为 10毫秒、 偏移量为 2毫秒, 则表示在每个无线帧的子帧 2 上为 UE配置该 SR资源, 即 UE可以在每个无线帧的子帧 2上使用 SR资源发送 SR。 再例如, 以 10毫秒为周期发送无线帧, 若 SR资源的周期为 20毫秒、 偏 移量为 3毫秒, 则表示在偶数无线帧的子帧 3上为 UE配置该 SR资源, 即 UE 可以在偶数无线帧的子帧 3上使用 SR资源发送 SR。 其中, 偶数无线帧的子 帧 3包括: 0号无线帧的子帧 3、 2号无线帧的子帧 3、 4号无线帧的子帧 3等。
对于本发明实施例, 由于 TDD上下行配比可以进行动态改变, 因此存 在子帧在部分无线帧中被指示为上行子帧,在部分无线帧中被指示为下行 子帧的情况。 此时, 存在为 UE配置的上行资源的位置与子帧方向发生冲突 的情况, 当 UE在上行资源发送信号, 并且该资源的子帧方向为下行时, UE 发送的信号会对其它 UE造成干扰; 同时, 由于此时 UE发送的信号为无用信 号, 因此会造成 UE发射功率的浪费。
可选地, 本发明实施例提供了一种上行资源的配置方法, 具体包括: 网络侧节点为 UE配置的上行资源, 在 UE的下行参考配比中的上行子帧和 I 或特殊子帧上。 其中, UE可以通过本发明实施例提供的方式动态改变 TDD 上下行配比。
其中, 当 UE仅对应一个服务小区时, UE在该服务小区的下行参考配比 为 UE的下行参考配比。 当 UE对应多个服务小区时, UE的主服务小区的下行 参考配比或者已经配置上述上行资源的服务小区为 UE的下行参考配比。
例如下表中所示,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集 合 {TDD上下行配比 0, TDD上下行配比 1 }中进行动态改变, UE的下行参考配 比为 TDD上下行配比 2 , 则按照本发明实施例提供的方法, 只有上行子帧 2、 上行子帧 7及特殊子帧 1、 特殊子帧 6可以配置上述上行资源。
Figure imgf000031_0001
其中, TDD动态配比集合可以是现有的 7种 TDD上下行配比的集合, 也 可以是新的 TDD上下行配比的集合, 本发明实施例不做限定。 在本发明实 施例中, TDD动态配比集合可以是固定的或配置的 TDD上下行配比的集合, 也可以是一段时间内 UE使用的 TDD上下行配比的集合。
对于本发明实施例,由于 UE的下行参考配比为各个 TDD上下行配比中, 该 U E的上行子帧和特殊子帧数量最少的配比 ,该配比中的上行子帧和特殊 子帧不会被动态配置下行子帧,因此通过将上述上行资源配置在该 UE的下 行参考配比中的上行子帧或者特殊子帧上,能够避免由于子帧方向改变所 造成的 UE之间互相干扰。
可替换地, 本发明实施例提供了另一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上行资源, 在 UE的 TDD动态配比集合中, 上行 子帧及特殊子帧数量最少的 TDD上下行配比所对应的上行子帧和 /或特殊 子帧上。
例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0, TDD上下行配比 1 }中进行动态改变, 其中, TDD下行配比 1中的上 行子帧及特殊子帧最少, 则按照本发明实施例提供的方法, 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8及特殊子帧 1、 特殊子帧 6可以配置上 述上行资源。
对于本发明实施例, 该 UE的 TDD动态配比集合中的上行子帧或者特殊 子帧数量最少的 TDD上下行配比中, 上行子帧和特殊子帧不会被动态配置 为下行子帧,因此将上述上行资源配置在该 UE的下行参考配比中的上行子 帧和 /或特殊子帧上, 能够避免避免由于子帧方向改变所造成的 UE之间互 相干扰, 同时可以增加可以配置上行资源的子帧数量。
进一步地, 本发明实施例提供了又一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上述上行资源的子帧位置必须为上行子帧和 / 或特殊子帧,对于其它没有配置上述上行资源的子帧位置的方向可以改变 为下行。
或者,网络侧节点为 UE配置的上述上行资源的子帧位置限制在物理下 例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 上行资源 SR资源的周期为 2 0 毫秒、 偏移量为 9毫秒, 则为偶数无线帧的子帧 9配置 SR资源, 即偶数无线 帧的子帧 9的方向不可改变为下行; 同时奇数无线帧的子帧 9没有配置 SR 资源, 即奇数无线帧的子帧 9的方向仍然可以改变为下行。 按照本发明实 施例提供的方法, 可以配置上述上行资源的子帧可以包括: 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8、 偶数无线帧的子帧 9 , 及特殊子帧 1、 特殊子帧 6。
对于本发明实施例,将上述上行资源配置在该 UE的下行参考配比中的 必须为上行子帧和 /或特殊子帧上, 能够避免避免由于子帧方向改变所造 成的 UE之间互相干扰, 同时可以最大限度的利用上行子帧和 /或特殊子帧 配置上行资源。
对于本发明实施例, 在跨站点载波聚合场景下, 各个网络侧节点可以 分别按照本发明实施例提供的方法, 为各个服务小区分别应用对应的 TDD 上下行配比; 同时, 各个网络侧节点之间还可以通过交互的方式, 为各个 服务小区分别应用对应的 TDD上下行配比。
具体地, 在跨站点载波聚合场景下, 微基站可以通过 Xn接口, 将各个 服务小区与各个 TDD上下行配比的对应关系及 TDD上下行配比的获取参数 等信息发送给宏基站,以使得宏基站可以根据各个微基站与各个 UE之间进 行通信的业务量, 为各个微基站应用对应的 TDD上下行配比。 同时, 宏基 站也可以根据自身业务量及负载情况等,为微基站应用各个服务小区与各 个 TDD上下行配比的对应关系及 TDD上下行配比的获取参数等信息,以使得 各个 i基站可以实时应用服务小区对应的 TDD上下行配比。

需要说明的是,本发明实施例中提供的用户设备中各个设备所对应的 其他相应描述, 可以参考图 5中的对应描述, 在此不再赘述。
本发明实施例提供的 TDD上下行配比的获取方法及装置, 首先网络侧 节点向用户设备发送物理下行控制信令及配置消息,然后用户设备根据 UE 的各个服务小区中的每个服务小区与对应的 TDD上下行配比命令在物理下 行控制信令中位置的对应关系, 从至少一个 TDD上下行配比命令中, 获取 各个服务小区分别对应的 TDD上下行配比。 与目前通过在物理下行控制信 令中仅携带一个 TDD上下行配比命令相比, 本发明实施例通过在物理下行 控制中携带多个 TDD上下行配比命令,并建立各个小区与各个 TDD上下行配 比命令在物理下行控制信令中的位置的对应关系,能够减少终端设备接收 物理下行控制信令的次数, 从而可以降低系统信令开销。
本发明实施例提供再一种 TDD上下行配比的获取方法, 如图 1 4所示, 所述方法包括:
1 4 01、网络侧节点按照用户设备 UE的各个服务小区中的每个服务小区 与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系 , 构 建物理下行控制信令。
其中, 物理下行控制信令中包括至少一个 TDD上下行配比命令, 至少 一个 TDD上下行配比命令中的每个 TDD上下行配比命令分别携带有对应的 TDD上下行配比。 在本发明实施例中, 通过在构建的物理下行物理信令中 携带多个 TDD上下行配比命令, 能够减少网络侧节点发送物理下行控制信 令的次数, 从而可以降低系统信令开销。
对于本发明实施例 , UE的各个服务小区中的每个服务小区与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系, 用于指示 UE 在接收到的物理下行控制信令中, 为各个服务小区获取对应的 TDD上下行 配比。 在本发明实施例中, 通过各个服务小区与各个 TDD上下行配比命令 的对应关系, 能够实现 UE正确地为各个服务小区分别应用对应的 TDD上下 行配比。
1 4 02、 网络侧节点向 UE发送物理下行控制信令。
可选地, 步骤 1 4 02可以为, 网络侧节点按照预设周期向 UE发送物理下 行控制信令。 其中, 预设周期可以由网络侧节点预先进行配置, 例如, 预 设周期可以为 1 0毫秒、 30毫秒、 50毫秒等。 在本发明实施例中, 网络侧节 点按照预设周期向 UE发送物理下行控制信令,能够使得 UE实时地为各个小 区配置对应的 TDD上下行配比, 从而可以实现 UE各个服务小区可以适应不 同业务量的变化。
1403、 网络侧节点向 UE发送配置消息。
其中,配置消息携带有 UE的各个服务小区中的每个服务小区与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系。 在本发明实 施例中, 各个小区的标识可以为各个小区的索引号, 各个 TDD上下行配比 的位置标识可以为各个 TDD上下行配比的位置索引号。 例如, 各个小区的 索引号可以为: 小区 1、 小区 2、 小区 3等, 各个 TDD上下行配比的位置索引 号可以为: 位置 1、 位置 2、 位置 3等。 在本发明实施例中, 配置消息可以 为系统广播消息或者专用 RRC ( Radio Resource Control, 无线资源控制) 消息, 也可以为新设计的消息, 或者在现有消息中新增加的 IE ( Information Element, 信息元), 本发明实施例不作限定。
对于本发明实施例, 各个服务小区与各个 TDD上下行配比命令的对应 关系用于指示, UE在接收到的物理下行控制信令中, 为各个服务小区获取 对应的 TDD上下行配比。 对于本发明实施例, 通过各个服务小区与各个 TDD 上下行配比命令的对应关系 ,能够实现 UE正确地为各个服务小区分别应用 对应的 TDD上下行配比。
对于本发明实施例, 网络侧节点为 UE配置的上行资源包括: 上行的 SR ( schedule reques t调度请求 ) 资源、 CQ I ( channel quality indicator 信道廣量指示) 4艮告资源, CSI ( Channel Status Information, 信道状 态信息 ) 资源, SRS ( sounding reference s igna 1监听参考信号 ) 资源, PRACH ( Physical Random Access Cha騰 1,物理随机接入信道) 资源等。 具体地, UE可以按照预设周期上报 SR资源、 CQI报告资源、 CSI资源、 PRACH 资源、 SRS资源等上行资源。 例如, 预设周期可以为: 1毫秒、 5毫秒、 10 毫秒、 20毫秒等。 在本发明实施例中, 可以通过资源对应的周期及偏移量 确定资源在 TDD上下行配比中的位置。 例如, 以 1 0毫秒为周期发送无线帧, 若 SR资源的周期为 1 0毫秒、 偏移量为 2毫秒, 则表示在每个无线帧的子帧 2 上为 UE配置该 SR资源, 即 UE可以在每个无线帧的子帧 2上使用 SR资源发送 SR。 再例如, 以 1 0毫秒为周期发送无线帧, 若 SR资源的周期为 2 0毫秒、 偏 移量为 3毫秒, 则表示在偶数无线帧的子帧 3上为 UE配置该 SR资源, 即 UE 可以在偶数无线帧的子帧 3上使用 SR资源发送 SR。 其中, 偶数无线帧的子 帧 3包括: 0号无线帧的子帧 3、 2号无线帧的子帧 3、 4号无线帧的子帧 3等。
对于本发明实施例, 由于 TDD上下行配比可以进行动态改变, 因此存 在子帧在部分无线帧中被指示为上行子帧,在部分无线帧中被指示为下行 子帧的情况。 此时, 存在为 UE配置的上行资源的位置与子帧方向发生冲突 的情况, 当 UE在上行资源发送信号, 并且该资源的子帧方向为下行时, UE 发送的信号会对其它 UE造成干扰; 同时, 由于此时 UE发送的信号为无用信 号, 因此会造成 UE发射功率的浪费。
可选地, 本发明实施例提供了一种上行资源的配置方法, 具体包括: 网络侧节点为 UE配置的上行资源, 在 UE的下行参考配比中的上行子帧和 I 或特殊子帧上。 其中, UE可以通过本发明实施例提供的方式动态改变 TDD 上下行配比。
其中, 当 UE仅对应一个服务小区时, UE在该服务小区的下行参考配比 为 UE的下行参考配比。 当 UE对应多个服务小区时, UE的主服务小区的下行 参考配比或者已经配置上述上行资源的服务小区为 UE的下行参考配比。
例如下表中所示,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集 合 {TDD上下行配比 0 , TDD上下行配比 1 }中进行动态改变, UE的下行参考配 比为 TDD上下行配比 2 , 则按照本发明实施例提供的方法, 只有上行子帧 2、 上行子帧 7及特殊子帧 1、 特殊子帧 6可以配置上述上行资源。
TDD上下行 转换间 子帧序号
配比序号 隔周期 0 1 2 3 4 5 6 7 8 9 0 5ms D S u u u D S u u u
1 5ms D S u u D D S u u D
2 5ms D s u D D D s u D D 其中, TDD动态配比集合可以是现有的 7种 TDD上下行配比的集合, 也 可以是新的 TDD上下行配比的集合, 本发明实施例不做限定。 在本发明实 施例中 , TDD动态配比集合可以是固定的或配置的 TDD上下行配比的集合, 也可以是一段时间内 UE使用的 TDD上下行配比的集合。
对于本发明实施例,由于 UE的下行参考配比为各个 TDD上下行配比中, 该 U E的上行子帧和特殊子帧数量最少的配比,该配比中的上行子帧和特殊 子帧不会被动态配置下行子帧,因此通过将上述上行资源配置在该 UE的下 行参考配比中的上行子帧或者特殊子帧上,能够避免由于子帧方向改变所 造成的 UE之间互相干扰。
可替换地, 本发明实施例提供了另一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上行资源, 在 UE的 TDD动态配比集合中, 上行 子帧及特殊子帧数量最少的 TDD上下行配比所对应的上行子帧和 /或特殊 子帧上。
例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 其中, TDD下行配比 1中的上 行子帧及特殊子帧最少, 则按照本发明实施例提供的方法, 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8及特殊子帧 1、 特殊子帧 6可以配置上 述上行资源。
对于本发明实施例,该 UE的 TDD动态配比集合中的上行子帧和 /或特殊 子帧数量最少的 TDD上下行配比中, 上行子帧和特殊子帧不会被动态配置 为下行子帧,因此将上述上行资源配置在该 UE的下行参考配比中的上行子 帧和 /或者特殊子帧上, 能够避免避免由于子帧方向改变所造成的 UE之间 互相干扰, 同时可以增加可以配置上行资源的子帧数量。 进一步地, 本发明实施例提供了又一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上述上行资源的子帧位置必须为上行子帧或者 特殊子帧,对于其它没有配置上述上行资源的子帧位置的方向可以改变为 下行。
或者,网络侧节点为 UE配置的上述上行资源的子帧位置限制在物理下 行控制信令指示该子帧为上行子帧或者特殊子帧的子帧位置。
例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 上行资源 SR资源的周期为 2 0 毫秒、 偏移量为 9毫秒, 则为偶数无线帧的子帧 9配置 S R资源, 即偶数无线 帧的子帧 9的方向不可改变为下行; 同时奇数无线帧的子帧 9没有配置 S R 资源, 即奇数无线帧的子帧 9的方向仍然可以改变为下行。 按照本发明实 施例提供的方法, 可以配置上述上行资源的子帧可以包括: 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8、 偶数无线帧的子帧 9, 及特殊子帧 1、 特殊子帧 6。
对于本发明实施例,将上述上行资源配置在该 UE的下行参考配比中的 必须为上行子帧和 /或特殊子帧上, 能够避免避免由于子帧方向改变所造 成的 UE之间互相干扰, 同时可以最大限度的利用上行子帧和 /或特殊子帧 配置上行资源。
对于本发明实施例, 在跨站点载波聚合场景下, 各个网絡侧节点可以 分别按照本发明实施例提供的方法, 为各个服务小区分别应用对应的 TDD 上下行配比; 同时, 各个网絡侧节点之间还可以通过交互的方式, 为各个 服务小区分别应用对应的 TDD上下行配比。
具体地, 在跨站点载波聚合场景下, 微基站可以通过 Xn接口, 将各个 服务小区与各个 TDD上下行配比的对应关系及 TDD上下行配比的获取参数 等信息发送给宏基站,以使得宏基站可以根据各个微基站与各个 UE之间进 行通信的业务量, 为各个微基站应用对应的 TDD上下行配比。 同时, 宏基 站也可以根据自身业务量及负载情况等,为微基站应用各个服务小区与各 个 TDD上下行配比的对应关系及 TDD上下行配比的获取参数等信息,以使得 各个 i基站可以实时应用服务小区对应的 TDD上下行配比。
进一步地, 作为图 14所示方法的具体实现, 本发明实施例提供了一种 TDD上下行配比的获取装置, 如图 15所示, 所述装置的实体可以为网络侧 节点, 所述装置包括: 构建单元 151、 发送单元 152。

本发明实施例提供又一种 TDD上下行配比的获取方法, 如图 1 7所示, 所述方法包括:
1 7 01、 网絡侧节点向 UE发送配置消息。
其中,配置消息携带有 UE的各个服务小区中的每个服务小区与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系。 在本发明实 施例中, 各个小区的标识可以为各个小区的索引号, 各个 TDD上下行配比 的位置标识可以为各个 TDD上下行配比的位置索引号。 例如, 各个小区的 索引号可以为: 小区 1、 小区 2、 小区 3等, 各个 TDD上下行配比的位置索引 号可以为: 位置 1、 位置 2、 位置 3等。 在本发明实施例中, 配置消息可以 为系统广播消息或者专用 RRC ( Radio Resource Control, 无线资源控制) 消息, 也可以为新设计的消息, 或者在现有消息中新增加的 IE ( Information Element, 信息元), 本发明实施例不作限定。
对于本发明实施例, UE的各个服务小区中的每个服务小区与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系, 用于指示 UE 在接收到的物理下行控制信令中, 为各个服务小区获取对应的 TDD上下行 配比。 在本发明实施例中, 通过各个服务小区与各个 TDD上下行配比命令 的对应关系, 能够实现 UE正确地为各个服务小区分别应用对应的 TDD上下 行配比。
对于本发明实施例, 网络侧节点发送的配置消息中, UE的各个服务小 区的标识与各个 TDD上下行配比命令的位置标识的对应关系所对应的描 述, 可以参考实施例二中对应的描述, 在此不再贅述。
1702、 网络侧节点向 UE发送指示消息。
其中,指示消息可以用于指示 UE是否开启 TDD上下行配比的配置功能。 例如, 指示消息可以为开启或者关闭。
对于本发明实施例, 可以通过设计一个新的 IE作为指示消息。 例如, 设计一个布尔型变量作为指示消息, 若该布尔型变量的值为真, 则指示 UE 开启 TDD上下行配比的配置功能; 若该布尔型变量的值为假, 则指示 UE关 闭 TDD上下行配比的配置功能。 在本发明实施例中, 还可以通过设计一个 新的 RRC消息作为指示消息。
优选地,可以通过 TDD上下行配比的获取参数隐式指示 UE是否开启 TDD 上下行配比的配置功能。在本发明实施例中,通过隐式指示 UE是否开启 TDD 上下行配比的配置功能, 能够减少网络侧节点发送指示消息的次数, 从而 可以进一步降低系统信令开销。
其中, TDD上下行配比的获取参数可以为: 无线网络临时标识、 携带 各个 TDD上下行配比命令的物理下行控制信令发送周期、各个 TDD上行比例 配置参考、 各个 TDD下行比例配置参考、 各个 TDD上下行配比命令在物理下 行控制信令中的位置的标识、 UE的各个服务小区中的每个服务小区与对应 的 TDD上下行配比命令在物理下行控制信令中位置的对应关系等。 其中, 无线网络临时标识用于加掩携带各个 TDD上下行配比命令的物理下行控制 信令。 若预先配置有 TDD上下行配比的获取参数, 则指示 UE开启 TDD上下行 配比的配置功能; 若预先未配置 TDD上下行配比的获取参数, 则指示 UE关 闭 TDD上下行配比的配置功能。
可选地, 指示消息还可以用于指示服务小区是否开启 TDD上下行配比 的配置功能。 例如, 指示消息可以为开启或者关闭。
对于本发明实施例, 可以通过设计一个新的 I E作为指示消息。 例如, 设计一个布尔型变量作为指示消息, 若该布尔型变量的值为真, 则指示服 务小区开启 TDD上下行配比的配置功能; 若该布尔型变量的值为假, 则指 示服务小区关闭 TDD上下行配比的配置功能。 在本发明实施例中, 还可以 通过设计一个新的 RRC ( Ra d i o Re s ou r ce Con t ro l , 无线资源控制) 消息 作为指示消息。
优选地, 可以通过 TDD上下行配比的获取参数隐式指示服务小区是否 开启 TDD上下行配比的配置功能。 在本发明实施例中, 通过隐式指示服务 小区是否开启 TDD上下行配比的配置功能, 能够减少网络侧节点发送指示 消息的次数, 从而可以进一步降低系统信令开销。
其中, TDD上下行配比的获取参数可以为: 无线网络临时标识、 携带 各个 TDD上下行配比命令的物理下行控制信令发送周期、各个 TDD上行比例 配置参考、 各个 TDD下行比例配置参考、 各个 TDD上下行配比命令在物理下 行控制信令中的位置的标识、 UE的各个服务小区中的每个服务小区与对应 的 TDD上下行配比命令在物理下行控制信令中位置的对应关系等。 其中, 无线网络临时标识用于加掩携带各个 TDD上下行配比命令的物理下行控制 信令若预先配置有 TDD上下行配比的获取参数, 则指示服务小区开启 TDD 上下行配比的配置功能; 若预先未配置 TDD上下行配比的获取参数, 则指 示服务小区关闭 TDD上下行配比的配置功能。
对于本发明实施例, 步骤 1 7 02为可选步骤。
1 7 03、网络侧节点按照用户设备 UE的各个服务小区中的每个服务小区 与对应的 TDD上下行配比命令在物理下行控制信令中位置的对应关系, 构 建物理下行控制信令。
其中, 物理下行控制信令中包括至少一个 TDD上下行配比命令, 至少 一个 TDD上下行配比命令中的每个 TDD上下行配比命令分别携带有对应的 TDD上下行配比。 在本发明实施例中, 通过在物理下行物理信令中携带多 个 TDD上下行配比命令 , 能够减少网絡侧节点发送物理下行控制信令的次 数, 进而可以降低系统信令开销。
对于本发明实施例, 物理下行控制信令中包括的至少一个 TDD上下行 配比命令中的每个 TDD上下行配比命令分别对应至少一个服务小区。 在本 发明实施例中, 物理控制信令中的每个 TDD上下行配比命令可以对应一个 服务小区, 也可以对应一组服务小区, 本发明实施例不做限定。 其中, TDD 上下行配比命令对应的一组服务小区可以是相同频带( Ba nd )中的多个服 务小区, 也可以是不同频带中的多个服务小区。
1 7 04、 网络侧节点向 UE发送物理下行控制信令。
可选地, 步骤 1 7 04可以为, 网络侧节点按照预设周期向 UE发送物理下 行控制信令。 其中, 预设周期可以由网络侧节点预先进行配置, 例如, 预 设周期可以为 1 0毫秒、 30毫秒、 40毫秒等。 在本发明实施例中, 通过网络 侧节点按照预设周期向 UE发送物理下行控制信令,能够使得 UE实时地为各 个服务小区应用对应的 TDD上下行配比, 从而可以实现 UE的各个服务小区 可以适应不同业务量的变化。
优选地, 当物理下行控制信令中的每个 T D D上下行配比对应一组小区 时, 步骤 1704还可以为, 网络侧节点向一组 UE发送物理下行控制信令。 在 本发明实施例中, 网络侧节点通过向一组 UE发送物理下行控制信令, 能够 避免网络侧节点分别向不同的 UE发送物理下行控制信令,从而可以减少网 络侧节点发送物理下行控制信令的次数, 进而可以进一步降低信令开销。
对于本发明实施例, 网络侧节点为 UE配置的上行资源包括: 上行的 SR ( schedule reques t调度请求 ) 资源、 CQI ( channel quality indicator 信道质量指示) 4艮告资源, CSI ( Channel Status Information, 信道状 态信息 ) 资源, SRS ( sounding reference s igna 1监听参考信号 ) 资源, P ACH ( Physical Random Access Cha誕 1,物理随机接入信道) 资源等。 具体地, UE可以按照预设周期上报 SR资源、 CQI报告资源、 CSI资源、 PRACH 资源、 SRS资源等上行资源。 例如, 预设周期可以为: 1毫秒、 5毫秒、 10 毫秒、 20毫秒等。 在本发明实施例中, 可以通过资源对应的周期及偏移量 确定资源在 TDD上下行配比中的位置。 例如, 以 10毫秒为周期发送无线帧, 若 SR资源的周期为 10毫秒、 偏移量为 2毫秒, 则表示在每个无线帧的子帧 2 上为 UE配置该 SR资源, 即 UE可以在每个无线帧的子帧 2上使用 SR资源发送 SR。 再例如, 以 10毫秒为周期发送无线帧, 若 SR资源的周期为 20毫秒、 偏 移量为 3毫秒, 则表示在偶数无线帧的子帧 3上为 UE配置该 SR资源, 即 UE 可以在偶数无线帧的子帧 3上使用 SR资源发送 SR。 其中, 偶数无线帧的子 帧 3包括: 0号无线帧的子帧 3、 2号无线帧的子帧 3、 4号无线帧的子帧 3等。
对于本发明实施例, 由于 TDD上下行配比可以进行动态改变, 因此存 在子帧在部分无线帧中被指示为上行子帧,在部分无线帧中被指示为下行 子帧的情况。 此时, 存在为 UE配置的上行资源的位置与子帧方向发生冲突 的情况, 当 UE在上行资源发送信号, 并且该资源的子帧方向为下行时, UE 发送的信号会对其它 UE造成干扰; 同时, 由于此时 UE发送的信号为无用信 号, 因此会造成 UE发射功率的浪费。
可选地, 本发明实施例提供了一种上行资源的配置方法, 具体包括: 网络侧节点为 UE配置的上行资源, 在 UE的下行参考配比中的上行子帧和 I 或特殊子帧上。 其中, UE可以通过本发明实施例提供的方式动态改变 TDD 上下行配比。
其中, 当 UE仅对应一个服务小区时, UE在该服务小区的下行参考配比 为 UE的下行参考配比。 当 UE对应多个服务小区时, UE的主服务小区的下行 参考配比或者已经配置上述上行资源的服务小区为 UE的下行参考配比。
例如下表中所示,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集 合 {TDD上下行配比 0 , TDD上下行配比 1 }中进行动态改变, UE的下行参考配 比为 TDD上下行配比 2, 则按照本发明实施例提供的方法, 只有上行子帧 2、 上行子帧 7及特殊子帧 1、 特殊子帧 6可以配置上述上行资源。
Figure imgf000049_0001
其中, TDD动态配比集合可以是现有的 7种 TDD上下行配比的集合, 也 可以是新的 TDD上下行配比的集合, 本发明实施例不做限定。 在本发明实 施例中, TDD动态配比集合可以是固定的或配置的 TDD上下行配比的集合, 也可以是一段时间内 UE使用的 TDD上下行配比的集合。
对于本发明实施例,由于 UE的下行参考配比为各个 TDD上下行配比中, 该 U E的上行子帧和特殊子帧数量最少的配比,该配比中的上行子帧和特殊 子帧不会被动态配置下行子帧,因此通过将上述上行资源配置在该 UE的下 行参考配比中的上行子帧或者特殊子帧上,能够避免由于子帧方向改变所 造成的 UE之间互相干扰。
可替换地, 本发明实施例提供了另一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上行资源, 在 UE的 TDD动态配比集合中, 上行 子帧及特殊子帧数量最少的 TDD上下行配比所对应的上行子帧和 /或特殊 子帧上。
例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 其中, TDD下行配比 1中的上 行子帧及特殊子帧最少, 则按照本发明实施例提供的方法, 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8及特殊子帧 1、 特殊子帧 6可以配置上 述上行资源。
对于本发明实施例,该 UE的 TDD动态配比集合中的上行子帧和 /或特殊 子帧数量最少的 TDD上下行配比中, 上行子帧和特殊子帧不会被动态配置 为下行子帧,因此将上述上行资源配置在该 UE的下行参考配比中的上行子 帧和或者特殊子帧上,能够避免避免由于子帧方向改变所造成的 UE之间互 相干扰, 同时可以增加可以配置上行资源的子帧数量。
进一步地, 本发明实施例提供了又一种上行资源的配置方法, 具体包 括: 网络侧节点为 UE配置的上述上行资源的子帧位置必须为上行子帧和 / 或特殊子帧,对于其它没有配置上述上行资源的子帧位置的方向可以改变 为下行。
或者,网络侧节点为 UE配置的上述上行资源的子帧位置限制在物理下 例如,若为 UE配置的 TDD上下行配比可以在 TDD动态配比集合 {TDD上下 行配比 0 , TDD上下行配比 1 }中进行动态改变, 上行资源 SR资源的周期为 2 0 毫秒、 偏移量为 9毫秒, 则为偶数无线帧的子帧 9配置 S R资源, 即偶数无线 帧的子帧 9的方向不可改变为下行; 同时奇数无线帧的子帧 9没有配置 S R 资源, 即奇数无线帧的子帧 9的方向仍然可以改变为下行。 按照本发明实 施例提供的方法, 可以配置上述上行资源的子帧可以包括: 上行子帧 2、 上行子帧 3、 上行子帧 7、 上行子帧 8、 偶数无线帧的子帧 9 , 及特殊子帧 1、 特殊子帧 6。 对于本发明实施例,将上述上行资源配置在该 UE的下行参考配比中的 必须为上行子帧和 /或特殊子帧上, 能够避免避免由于子帧方向改变所造 成的 UE之间互相干扰, 同时可以最大限度的利用上行子帧和 /或特殊子帧 配置上行资源。
对于本发明实施例, 在跨站点载波聚合场景下, 各个网络侧节点可以 分别按照本发明实施例提供的方法, 为各个服务小区分别应用对应的 TDD 上下行配比; 同时, 各个网络侧节点之间还可以通过交互的方式, 为各个 服务小区分别应用对应的 TDD上下行配比。
具体地, 在跨站点载波聚合场景下, 微基站可以通过 Xn接口, 将各个 服务小区与各个 TDD上下行配比的对应关系及 TDD上下行配比的获取参数 等信息发送给宏基站,以使得宏基站可以根据各个微基站与各个 UE之间进 行通信的业务量, 为各个微基站应用对应的 TDD上下行配比。 同时, 宏基 站也可以根据自身业务量及负载情况等,为微基站应用各个服务小区与各 个 TDD上下行配比的对应关系及 TDD上下行配比的获取参数等信息,以使得 各个 基站可以实时应用服务小区对应的 TDD上下行配比。
进一步地, 作为图 1 7所示方法的具体实现, 本发明实施例提供了一种 TDD上下行配比的获取装置, 如图 1 8所示, 所述装置的实体可以为网络侧 节点, 所述装置包括: 构建单元 181、 发送单元 1 82。

发送单元 182发送的配置消息携带有 UE的各个服务小区中的每个服务 小区的标识与对应的 TDD上下行配比命令在物理下行控制信令中位置的标 识的对应关系。

需要说明的是, 本发明实施例中提供的 TDD上下行配比的获取装置中 各功能单元所对应的其他相应描述, 可以参考图 17中的对应描述, 在此不 再赘述。
再进一步地, 所述 TDD上下行配比的获取装置的实体可以为网络侧节 点, 如图 19所示, 所述网络侧节点可以包括: 处理器 191、 输入设备 192、 输出设备 193、 存储器 194, 所述输入设备 192、 输出设备 193及存储器 194 分别与处理器 191相连接。
