Description
一种协调调度方法及装置 技术领域
本申请涉及通信领域, 尤其涉及一种协调调度方法及装置。
背景技术
无线通信领域面临着数据业务***增长的压力,为了提高网络容量和 降低传输成本,业内提出了一种异构网络( Heterogeneous Network , Hetnet ) 技术。 Hetnet由多个不同大小、 不同类型的小区一起构成, 包括: 宏小区
( Macro cell )和 小区。 其中 小区包括: 型小区 ( Micro cell )、 小区 (Pico Cell )、 毫 小区 ( Femto Cell )、 远端射频头 ( Remote Radio Head , RRH ) 形态的小区等。 通过为话务密集的区域部署更多的微小区, 可以有效提高该区域的网络容量, 并且微小区因规模较小, 其建设成本
( Capital Expenditure , Cap ax ) 和运营成本 ( Operating Expense , Opex ) 都比较低, 因此 Hetnet 受到众多运营商的重视, 是无线网络演进的一个 重要方向。
现有技术中, 当微小区与宏小区同频部署时, 如图 1所示, 最外圈是 宏小区覆盖区域, 最内圈是微小区覆盖区域, 虚线圈与最内圈之间的环形 区域是软切换区域, 此时, 微小区中心用户会对在软切换区的宏小区用户 产生下行干扰,软切换区的宏小区用户会对软切换区的微小区用户产生上 行干扰。 同样的, 还会存在反方向的干扰, 即宏小区中心用户会对软切换 区的微小区用户产生下行干扰,软切换区的微小区用户会对软切换区的宏 小区用户产生上行干扰。
并且, 由于微小区和宏小区的同频部署, 微小区的覆盖范围收缩, 为 了使更多的用户能接入微小区,对微小区覆盖的场景采用覆盖拓展( Range Extension, RE ) 技术。 但当对微小区覆盖的场景进行 RE拓展之后, 宏小 区用户和微小区用户间的干扰问题会加剧。
因此,急需一种方案以解决上述异构网络部署中小区间同频干扰的问 题。

本申请一实施例提供一种信息传递方法, 如图 2所示, 该方法可以包 括:
101、 第一节点接收第二节点发送的协调调度请求。
其中, 在同频部署场景下, 宏小区和微小区之间存在干扰问题, 即第 一节点小区和第二节点小区存在干扰。为了减小第一节点小区和第二节点 小区间的干扰, 第二节点可以向第一节点发送协调调度请求, 以便于第一 节点根据协调调度请求对第一用户进行调度。
其中, 所述第一节点既可以是基站也可以是 RNC , 第二节点也既可 以是基站也可以是 RNC。 所述第一节点小区是微小区时第二节点小区为
宏小区, 或者第一节点小区是宏小区时第二节点小区是微小区, 或者所述 第一节点小区是微小区时第二节点小区微小区,或者第一节点小区是宏小 区时第二节点小区是宏小区。
102、 依据第一弱子帧样式, 在第一弱子帧采用比正常子帧低的功率 发送第一用户的下行数据信道或比正常子帧低的服务授权 ( Serving Grant, SG ) 调度第一用户的上行数据信道; 其中所述第一用户包括第一 节点小区中对第二节点小区造成干扰的用户和 /或软切换区用户。
本文所述弱子帧, 对数据信道, 在下行是指发射功率比正常子帧的发 射功率低的帧,或者,在上行是指服务授权比正常子帧的服务授权低的帧。
其中, 在第一节点接收到第二节点发送的协调调度请求之后, 根据接 收到的所述协调调度请求中携带的第一弱子帧样式,在第一弱子帧采用比 正常子帧低的功率发送第一用户的下行数据信道或比正常子帧低的 SG调 度第一用户的上行数据信道,以使得第一用户对第二节点小区中软切换区 用户和其他被干扰用户受到的干扰减小。 例如, 正常子帧采用的功率或 SG为 X, 在第一节点接收到第二节点发送的协调调度请求之后, 可以根 据协调调度请求中携带的第一弱子帧样式, 在第一弱子帧采用低于 X (如 X/10、 X/2 ) 的功率发送第一用户的下行数据信道或低于 X的 SG调度第 一用户的上行数据信道。其中所述第一用户包括第一节点小区中对第二节 点小区造成干扰的用户和 /或软切换区用户。
需要说明的是,第一节点只在第一弱子帧采用比正常子帧低的功率发 送第一用户的下行数据信道或比正常子帧低的 SG调度第一用户的上行数 据信道,而在第一弱子帧不采用比正常子帧低的功率发送第一用户的下行 控制信令。
本申请实施例提供的一种协调调度方法,第一节点在接收第二节点发 送的协调调度请求之后,依据第一弱子帧样式在第一弱子帧采用比正常子 帧低的功率发送第一用户的下行数据信道或比正常子帧低的服务授权 SG 调度第一用户的上行数据信道,以使得第二节点可以在第一弱子帧正常调
度受到第一用户干扰的第二节点小区用户,可以减少中心用户对软切换区 用户的干扰和软切换区用户之间的干扰,从而降低了现有技术中宏小区和 微小区同频部署时的干扰。
本申请另一实施例还提供一种协调调度方法, 如图 3所示, 该方法可 以包括:
201、 第一节点和第二节点进行信息交互。
在 Hentnet网络部署中 ,当第一节点小区和第二节点小区同频部署时 , 微小区的信号覆盖收缩很快, 现有技术中为了扩大微小区的覆盖范围, 采 用了 RE拓展技术, 但是在进行 RE拓展之后, 软切换区用户数量增加, 使得微小区和宏小区之间的干扰更加严重。
在这种情况下, 为了减小第二节点小区受到的干扰, 第二节点可以与 第一节点进行协调,指示第一节点采用比正常子帧低的功率发送第一用户 的下行数据信道或者比正常子帧低的 SG调度第一用户的上行数据信道, 以使得第一节点小区对第二节点小区造成的干扰可以减小,在进行协调调 度之前会与第一节点进行信息交互, 为协调调度做准备。 除了进行信息交 互外,第二节点(或第一节点)也可以向控制节点报告需要进行交互流程; 若第一节点和第二节点在同一控制节点, 可以直接向控制节点报告, 若不 在同一控制节点, 第一节点和第二节点也可在控制节点间交互。 其中, 交 互信息的过程可以包括: 与所述第二节点交互协调调度能力信息, 和 /或 与所述第二节点进行无线帧对齐, 和 /或与所述第二节点交互被干扰情况, 和 /或与所述第二节点交互上行用户吞吐量的和 /或下行用户吞吐量。并且, 信息的交互可以是周期性的, 也可以是由事件触发的。
202、 第一节点接收第二节点发送的下行协调调度请求。
其中, 在进行信息交互之后, 第二节点可以根据交互结果确定是否向 第一节点下发下行协调调度请求,也可以根据交互结果确定在下发的下行 协调调度请求中携带的协调调度模式标识。所述下行协调调度请求中可以 包含所述第一弱子帧样式、 协调调度模式标识和 /或弱子帧增减指示。
具体的, 所述协调调度请求中包含协调调度模式标识, 所述协调调度 模式标识可以指示第一模式或第二模式。第一模式为所述第一节点在第一 弱子帧采用比正常子帧低的功率发送第一用户的下行数据信道。第二模式 为所述第一节点在第一弱子帧采用比正常子帧低的功率发送第一用户的 下行数据信道,并且所述第二节点在第二弱子帧采用比正常子帧低的功率 发送第二用户的下行数据信道, 其中所述第二用户包括: 所述第二节点小 区中对所述第一节点小区造成干扰的用户和 /或软切换区用户。
进一步的,确定协调调度模式为所述第一模式的触发条件可以包括以 下任一个: 所述第一节点小区和第二节点小区的软切换区有至少一个用 户; 所述软切换区中用户数量超过预定数量门限; 所述第一节点小区未进 行覆盖扩展 RE或 RE门限小于预定扩展门限。 确定所述协调调度模式为 所述第二模式的触发条件可以包括以下任一个:所述软切换区中有至少一 个第二节点小区的用户;所述第一节点小区的 RE门限高于预定扩展门限; 所述第一节点小区的用户吞吐量低于所述第二节点小区用户吞吐量。在选 择协调调度模式时,可以参考的触发条件包括但不局限于本申请中提到的 触发条件, 本申请在此不做限定。
203、 第一节点依据所述第一弱子帧样式, 在所述第一弱子帧采用比 正常子帧低的功率发送第一用户的下行数据信道。
其中,所述第一弱子帧样式是指第二节点指示第一节点可以在那些弱 子帧使用比正常子帧低的功率发送第一用户的下行数据信道。弱子帧样式 可以通过包含在下行协调调度请求或下行协调调度响应中的第一弱子帧 样式进行配置, 也可以预先在第一节点和 /或第二节点上配置所述第一弱 子帧样式。 例如, 以第一节点小区是微小区同时第二节点小区是宏小区为 例, 如图 4 ( a ) 所示, 微小区 1在子帧 2和子帧 6采用比正常子帧低的 功率发送第一用户的下行数据信道。由于对宏小区造成干扰的用户可能不 止一个,所以宏小区也可以在下行协调调度请求中携带对该宏小区造成干 扰的其他小区 (如微小区 2 ) 的弱子帧样式, 即图中微小区 2在子帧 3和
子帧 7 采用比正常子帧低的功率发送对宏小区造成干扰的用户的下行数 据信道。
所述弱子帧增减指示, 用于指示对方调整弱子帧样式中弱子帧的个 数。 例如, 第二节点小区发现第一节点小区造成的干扰情况较低时, 可以 向第一节点发送弱子帧减少指示, 以使得第一节点减少第一弱子帧的个 数。 或者, 第二节点在和第一节点进行信息交互的过程中发现第一节点小 区造成的干扰较严重, 则可以向第一节点发送弱子帧增加指示, 以使得第 一节点增加第一弱子帧的个数。
其中, 在第一节点接收到第二节点发送的下行协调调度请求之后, 可 以根据下行协调调度请求中携带的第一弱子帧样式、协调调度模式标识和 /或弱子帧增减指示, 对第一用户在第一弱子帧采用比正常子帧低的功率 发送下行数据信道。其中所述第一用户包括所述第一节点小区中对所述第 二节点小区造成干扰的用户和 /或软切换区用户。
需要说明的是, 步骤 203中主要以第一模式为例进行描述, 若下行协 调调度请求中携带的协调调度模式为第二模式时,所述第一节点可在第一 弱子帧采用比正常子帧低的功率发送第一用户的下行数据信道,并且所述 第二节点也可在第二弱子帧采用比正常子帧低的功率发送第二用户的下 行数据信道。 其中所述第二用户包括: 所述第二节点小区中对所述第一节 点小区造成干扰的用户和 /或软切换区用户。
进一步可选的, 在步骤 203第一节点依据所述第一弱子帧样式, 在所 述第一弱子帧采用比正常子帧低的功率发送第一用户的下行数据信道之 前, 还可以包括以下步骤 204-207。 如图 5所示, 以下以第二模式为例进 行描述:
204、 第一节点确定协调调度模式。
其中, 第一节点在向所述第二节点发送下行协调调度响应之前, 可以 先确定采用哪种协调调度模式,其中第一节点选择协调调度模式的方法与 步骤 202中第二节点选择协调调度模式的方法类似,所以协调调度模式的
触发条件可以参考步骤 202 , 本发明在此不作详细赘述。 例如, 第一节点 接收到协调调度请求中携带的协调调度模式标识为第一模式,而第一节点 根据步骤 201 的交互结果确定第二节点小区中用户对第一节点小区的软 切换区用户也造成严重干扰, 则可以选择第二模式, 并携带在下行协调调 度响应中。 这样, 第一节点在第一弱子帧采用比正常子帧低的功率发送第 一用户的下行数据信道的同时,所述第二节点在第二弱子帧采用比正常子 帧低的功率发送第二用户的下行数据信道,从而不仅第一节点小区可以减 少对第二节点小区的干扰,第二节点小区也可以减小对第一节点小区的软 切换区用户的干扰。
205、 第一节点向所述第二节点发送下行协调调度响应。
其中, 在所述第一节点确定采用何种协调调度模式之后, 向所述第二 节点发送下行协调调度响应,其中所述下行协调调度响应中包含为第二节 点配置的第二弱子帧样式、 协调调度模式标识和 /或弱子帧增减指示。 所 述协调调度模式标识,用于指示所述第二节点在第二弱子帧采用比正常子 帧低的功率发送第二用户的下行数据信道。 其中, 协调调度响应可以是第 一节点主动发起的, 也可以是收到第二节点的请求后发起的。
206、 第二节点在第二弱子帧采用比正常子帧低的功率发送第二用户 的下行数据信道。
其中, 在第二节点接收到所述第一节点发送的下行协调调度响应时, 根据所述下行协调调度响应中携带的协调调度模式标识,在第二弱子帧采 用比正常子帧低的功率发送第二用户的下行数据信道。 例如, 以第一节点 小区是微小区同时第二节点小区是宏小区为例, 如图 4 ( b ) 所示, 微小 区 1在子帧 2和子帧 6采用比正常子帧低的功率发送第一用户的下行数据 信道,微小区 2在子帧 3和子帧 7采用比正常子帧低的功率发送对宏小区 造成干扰的用户的下行数据信道, 同时, 宏小区在弱子帧 4 和弱子帧 8 采用比正常子帧低的功率发送第二用户的下行数据信道。
207、 第一节点依据所述第二弱子帧样式, 在所述第二弱子帧调度第
三用户。所述第三用户包括所述第一节点小区中被所述第二用户干扰的用 户。
其中, 在所述第二模式下, 由于第二节点采用了比正常子帧低的功率 发送第二用户的下行数据信道,避免对第一节点小区中的第三用户造成干 扰, 因此第一节点可以依据所述第二弱子帧样式, 在所述第二弱子帧调度 所述第三用户。 其中, 所述第三用户包括所述第一节点小区中被所述第二 用户干扰的用户。 具体的, 可以采用正常的功率发送第三用户的下行数据 信道, 也可以采用调高的功率发送第三用户的下行数据信道, 本申请实施 例对此不做限定。

并且, 在进行下行协调调度的过程中, 不仅第一节点可以在第一弱子 小区对第二节点小区的干扰,第二节点也可以在第二弱子帧对第二用户采 用比正常子帧低的功率发送下行数据信道,减少第二节点小区对第一节点 小区的干扰,这样可以使得第一节点小区和第二节点小区间的干扰进一步 减小。

其中, 在第一节点接收到第二节点发送的上行协调调度请求之后, 可 以根据上行协调调度请求中携带的第一弱子帧样式、协调调度模式标识和 /或弱子帧增减指示,对第一用户在第一弱子帧采用比正常子帧低的 SG调 度上行数据信道。
需要说明的是, 步骤 303中主要以第一模式为例进行描述, 若上行协 调调度请求中携带的协调调度模式为第二模式时,所述第一节点可在第一 弱子帧采用比正常子帧低的 SG调度所述第一用户的上行数据信道, 并且 所述第二节点也可在第二弱子帧采用比正常子帧低的 SG调度第二用户的 上行数据信道。

其中, 在所述第二模式下, 由于第二节点采用了比正常子帧低的 SG 调度第二用户的上行数据信道,避免对第一节点小区中的第三用户造成干 扰, 因此第一节点可以依据所述第二弱子帧样式, 在所述第二弱子帧调度 所述第三用户。 具体的, 可以采用正常的 SG调度第三用户的上行数据信 道, 也可以采用调高的 SG调度第三用户的上行数据信道, 本申请实施例 对此不做限定。
需要说明的是, 在本实施例的上行协调调度过程中, 部分步骤的具体 描述可以参考本申请另一实施例中下行协调调度的过程,部分参数和流程 的具体描述本发明实施例这里不再详细赘述。
需要说明的是,当所述协调调度请求包括上行协调调度请求和下行协 调调度请求, 即所述调度过程中既有上行协调调度还有下行协调调度时,
