为使本发明实施例的目的、 技术方案和优点更加清楚, 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做出创造性劳动前提 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个信息发送控制方法的流程图, 如图 1 所示, 该方法包括:
步骤 100, 确定第一基站在当前子帧中为干扰小区的用户分配的第一 控制信道单元组和第二基站在当前子帧中为受扰小区的用户分配的第二 控制信道单元组, 其中, 所述第一控制信道单元组所对应的时频资源与所 述第二控制信道单元组所对应的时频资源非时频对齐;
当第一基站与第二基站的信号覆盖区出现交叠时, 如果两基站时频对 齐, 两基站的信号会互相干扰, 以第一基站所覆盖的小区为干扰小区, 第 二基站所覆盖的小区为受扰小区为例详细说明, 反之亦然, 不再赘述。 当 第一基站在当前子帧中为干扰小区的用户分配的用于发送 PDCCH的时频资 源与第二基站在当前子帧中为受扰小区的用户分配的用于发送 PDCCH的时 频资源时频对齐时, 受扰小区的用户接收 PDCCH时会受到第一基站发射信 号的强干扰, 从而大大降低用户的正确接收概率, 其中, 用于发送 PDCCH 的时频资源具体说明如下: LTE中上下行的资源调度信息都是由 PDCCH来 承载的, 在一个子帧内可以有多个 PDCCH, 为了更有效地配置 PDCCH和其 他下行控制信道的时频资源, LTE定义了两个专用的控制信道资源单位: 资源粒子组(RE Group , REG)和控制信道单元(Control Channel Element , CCE) , 其中, 1个 REG由一子帧上的 4个资源粒子 RE组成, 一个 CCE由 9 个 REG构成。
为了使受扰小区的用户在接收第二基站发送的 PDCCH时避免受到第一 基站发射信号的强干扰, 本实施例提出一种信息发送控制方法。 具体地, 在系统中部署信息发送控制装置, 该装置可以与第一基站和第二基站进行 信息交互, 具体的部署位置可以是第一基站或者第二基站中, 或者是独立 于第一基站或者第二基站之外的网络实体中, 具体可以根据实际的应用需 要进行选择, 本实施例对此不加以限制。 信息发送控制装置分别与第一基 站和第二基站进行信息交互, 从而确定第一基站在当前子帧中为干扰小区 的用户分配的第一控制信道单元组所对应的时频资源和第二基站在当前 子帧中为受扰小区的用户分配的第二控制信道单元组所对应的时频资源 非时频对齐, 具体的确定方法很多, 比如: 信息发送控制装置首先分别获 取第一基站在当前子帧中为干扰小区的用户分配的第一控制信道单元组 所对应的时频资源以及第二基站在当前子帧中为受扰小区的用户分配的 第二控制信道单元组所对应的时频资源, 然后将第一控制信道单元组所对 应的时频资源与第二控制信道单元组所对应的时频资源进行比较, 若判断 获知第一控制信道单元组所对应的时频资源与第二控制信道单元组所对 应的时频资源非时频对齐, 则不再指示第一基站或者第二基站重新分配; 若判断获知第一控制信道单元组所对应的时频资源与第二控制信道单元 组所对应的时频资源时频对齐, 则指示第一基站或者第二基站在子帧中重 新分配用于发送 PDCCH的控制信道单元组, 然后再次进行比较, 直到确认 第一控制信道单元组所对应的时频资源与第二控制信道单元组所对应的 时频资源非时频对齐。 进一步地, 为了提高分配效率, 信息发送控制装置 可以向基站发送具体的指示信息, 举例说明: 信息发送控制装置向第一基 站发送第二控制信道单元组所对应的时频资源, 并指示第一基站参考第二 控制信道单元组所对应的时频资源, 在当前子帧中重新分配第一控制信道 单元组, 以使第一控制信道单元组对应的时频资源与第二控制信道单元组 所对应的时频资源非时频对齐。
步骤 101, 指示所述第一基站应用所述第一控制信道单元组向所述干 扰小区的用户发送物理下行控制信道 PDCCH所承载的控制信息, 同时指示 所述第二基站应用所述第二控制信道单元组向所述受扰小区的用户发送 PDCCH所承载的控制信息。
当信息发送控制装置确定第一控制信道单元组所对应的时频资源与 第二控制信道单元组所对应的时频资源非时频对齐时, 指示第一基站应用 第一控制信道单元组向干扰小区的用户发送物理下行控制信道 PDCCH所承 载的控制信息, 同时指示第二基站应用第二控制信道单元组向受扰小区的 用户发送 PDCCH所承载的控制信息, 当受扰小区的用户在接收第二基站应 用第二控制信道单元组发送的 PDCCH时, 由于第一控制信道单元组所对应 的时频资源与第二控制信道单元组所对应的时频资源非时频对齐, 所以用 户不再受到第一基站信号的干扰, 可以正确接收 PDCCH并解析其上承载的 控制信息。
本实施例提供的信息发送控制方法, 通过确定第一基站在当前子帧中 为干扰小区的用户分配的第一控制信道单元组和第二基站在当前子帧中 为受扰小区的用户分配的第二控制信道单元组, 其中, 两个控制信道单元 组所对应的时频资源非时频对齐, 并指示第一基站应用第一控制信道单元 组向干扰小区的用户发送 PDCCH所承载的控制信息, 同时指示第二基站应 用第二控制信道单元组向受扰小区的用户发送 PDCCH所承载的控制信息。 从而有效提高受扰用户正确接收控制信息的概率, 大大避免干扰信号的影 响, 提高了用户体验度。
图 2为本发明实施例提供的另一个信息发送控制方法的流程图, 如图 2所示, 该方法包括:
步骤 200, 获取所述第一基站对所述当前子帧中 N个时频资源粒子的 优先级进行的第一排序, 以及所述第二基站对所述当前子帧中 N个时频资 源粒子的优先级进行的第二排序, 其中, 所述第一排序和所述第二排序包 括: 第 N个时频资源粒子的优先级高于第 (N- 1 ) 个时频资源粒子的优先 级, 或者, 第 N个时频资源粒子的优先级低于第 (N- 1 ) 个时频资源粒子 的优先级;
信息发送控制装置分别获取第一基站对当前子帧中 N个时频资源粒子 的优先级进行的第一排序, 以及第二基站对当前子帧中 N个时频资源粒子 的优先级进行的第二排序, 其中, 所述第一排序和所述第二排序包括: 第 N个时频资源粒子的优先级高于第(N-1 )个时频资源粒子的优先级,或者, 第 N个时频资源粒子的优先级低于第 (N- 1 ) 个时频资源粒子的优先级。 举例说明: 第一基站对当前子帧中 N个时频资源粒子的优先级进行的第一 排序为: 从第一个时频资源粒子开始标识最高优先级, 从而当前子帧中符 号越小、 频率越低, 该时频位置的优先级越高, 第二基站对当前子帧中 N 个时频资源粒子的优先级进行的第二排序为: 从最后一个时频资源粒子开 始标识最高优先级, 从而当前子帧中符号越大, 频率越高, 该时频位置的 优先级越高。
步骤 201, 根据所述第一基站在所述当前子帧中预先配置的、 从时频 资源粒子到资源粒子组的第一映射关系, 从资源粒子组到控制信道单元的 第二映射关系, 以及所述第一排序中 N个时频资源粒子的优先级获取在所 述当前子帧中为干扰小区的用户提供的多个候选控制信道单元组的优先 级;
信息发送控制装置根据第一基站在当前子帧中预先配置的、 从时频资 源粒子到资源粒子组的第一映射关系, 从资源粒子组到控制信道单元的第 二映射关系, 以及第一排序中 N个时频资源粒子的优先级获取在所述当前 子帧中为干扰小区的用户分配的多个控制信道单元组的优先级, 具体地, 首先信息发送控制装置通过与第一基站交互获取第一基站根据协议定义 的当前子帧中从时频资源粒子 RE到资源粒子组 REG的第一映射关系, 以 及从资源粒子组 REG到控制信道单元 CCE的第二映射关系, 其中, 从时频 资源粒子 RE到资源粒子组 REG的第一映射关系即为各个资源粒子组具体 是由哪些时频资源粒子组成的, 从资源粒子组 REG到控制信道单元 CCE的 第二映射关系即为各个控制信道单元 CCE具体是由哪些时频资源粒子组组 成的, 从而信息发送控制装置再根据第一排序中 N个时频资源粒子的优先 级和映射关系应用函数模型获取在当前子帧中每个控制信道单元 CCE的优 先级, 具体如公式 (1 ) 和 (2 ) 所示;

其中, M为 CCEgroupt包含的具体 CCE 步骤 202, 根据所述第二基站在所述当前子帧中预先配置的、 从时频 资源粒子到资源粒子组的第三映射关系, 从资源粒子组到控制信道单元的 第四映射关系, 以及所述第二排序中 N个时频资源粒子的优先级获取在所 述当前子帧中为受扰小区的用户提供的多个候选控制信道单元组的优先 级;
信息发送控制装置根据第二基站在当前子帧中预先配置的、 从时频资 源粒子到资源粒子组的第三映射关系, 从资源粒子组到控制信道单元的第 四映射关系, 以及第二排序中 N个时频资源粒子的优先级获取在所述当前 子帧中为受扰小区的用户提供的多个候选控制信道单元组的优先级, 具体 地, 首先信息发送控制装置通过与第二基站交互获取第二基站根据协议定 义的当前子帧中从时频资源粒子 RE到资源粒子组 REG的第三映射关系, 以及从资源粒子组 REG到控制信道单元 CCE的第四映射关系, 其中, 从时 频资源粒子 RE到资源粒子组 REG的第三映射关系即为各个资源粒子组具 体是由哪些时频资源粒子组成的, 从资源粒子组 REG到控制信道单元 CCE 的第四映射关系即为各个控制信道单元 CCE具体是由哪些时频资源粒子组 组成的, 从而信息发送控制装置再根据第二排序中 N个时频资源粒子的优 先级和映射关系应用函数模型获取在当前子帧中每个控制信道单元 CCE的 优先级, 具体如公式 (1 ) 和 (2 ) 所示, 然后信息发送控制装置通过与第 二基站交互获取第二基站根据各用户的信道传输质量和级别为用户提供 的多个候选控制信道单元组, 即获知每个控制信道单元组都是由哪些控制 信道单元组成, 再根据每个控制信道单元 CCE的优先级应用函数模型获取 当前子帧中为用户提供的每个候选的控制信道单元组的优先级, 具体如公 式 (3 ) 所示。
步骤 203, 判断所述第一排序和所述第二排序是否相同, 进而根据所 述为干扰小区的用户提供的多个候选控制信道单元组的优先级, 以及所述 为受扰小区的用户提供的多个候选控制信道单元组的优先级确定所述第 一控制信道单元组和所述第二控制信道单元组;
信息发送控制装置获取在当前子帧中为干扰小区的用户提供的多个 候选控制信道单元组的优先级, 以及在当前子帧中为受扰小区的用户提供 的多个候选控制信道单元组的优先级之后, 先确定第一排序和所述第二排 序是否相同, 然后根据为干扰小区的用户提供的多个控制信道单元组的优 先级, 以及为受扰小区的用户提供的多个控制信道单元组的优先级确定所 述第一控制信道单元组和所述第二控制信道单元组, 具体为: 信息发送控 制装置若判断获知第一排序和所述第二排序相同, 则根据所述为干扰小区 的用户提供的多个候选控制信道单元组的优先级选择优先级最高的控制 信道单元组为所述第一控制信道单元组, 以及根据所述为受扰小区的用户 提供的多个候选控制信道单元组的优先级选择优先级最低的控制信道单 元组为所述第二控制信道单元组; 或者, 根据所述为干扰小区的用户提供 的多个候选控制信道单元组的优先级选择优先级最低的控制信道单元组 为所述第一控制信道单元组, 以及根据所述为受扰小区的用户提供的多个 候选控制信道单元组的优先级选择优先级最高的控制信道单元组为所述 第二控制信道单元组; 若判断获知所述第一排序和所述第二排序相反, 则 根据所述为干扰小区的用户提供的多个候选控制信道单元组的优先级选 择优先级最高的控制信道单元组为所述第一控制信道单元组, 以及根据所 述为受扰小区的用户提供的多个候选控制信道单元组的优先级选择优先 级最高的控制信道单元组为所述第二控制信道单元组; 或者, 根据所述为 干扰小区的用户提供的多个候选控制信道单元组的优先级选择优先级最 低的控制信道单元组为所述第一控制信道单元组, 以及根据所述为受扰小 区的用户提供的多个候选控制信道单元组的优先级选择优先级最低的控 制信道单元组为所述第二控制信道单元组。通过信息发送控制装置的上述 处理, 使所选择的第一控制信道单元组所对应的时频资源与第二控制信道 单元组所对应的时频资源相差较远, 从而相比现有技术, 尽可能的保证了 第一控制信道单元组所对应的时频资源与第二控制信道单元组所对应的 时频资源非时频对齐。
步骤 204, 指示所述第一基站应用所述第一控制信道单元组向所述干 扰小区的用户发送物理下行控制信道 PDCCH所承载的控制信息, 同时指示 所述第二基站应用所述第二控制信道单元组向所述受扰小区的用户发送 PDCCH所承载的控制信息。
当信息发送控制装置根据优先级确定第一控制信道单元组和第二控 制信道单元组之后, 指示第一基站应用第一控制信道单元组向干扰小区的 用户发送物理下行控制信道 PDCCH所承载的控制信息, 同时指示第二基站 应用第二控制信道单元组向受扰小区的用户发送 PDCCH所承载的控制信 息, 当受扰小区的用户在接收第二基站应用第二控制信道单元组发送的 PDCCH时, 由于第一控制信道单元组所对应的时频资源与第二控制信道单 元组所对应的时频资源非时频对齐, 所以用户不再受到第一基站信号的干 扰, 可以正确接收 PDCCH并解析其上承载的控制信息。
