在 HetNet中, 用户根据下行测量信号强度进行小区选择, 由于微基站的 发射功率相对宏基站的发射功率小很多, 这就导致微基站的覆盖范围小很多。 那么, 在 UMTS ( Universal Mobile Telecommunications System, 通用移动通言 系统)或者 LTE ( Long Temi Evolution, 长期演进) 系统中, 采用功率控制技 术, 使得离基站较远的用户需要较大的发射功率才能补偿路径损失和 "远近 效应" 的影响。 所以, 如果微小区边缘的宏基站用户设备距离宏基站距离较 远的话, 该宏基站用户设备就会使用较大的上行发射功率, 那么, 该宏基站 用户设备在进行上行数据传输时会对其附近的微小区产生严重的上行干扰, 降低微基站的上行容量。 发明内容

下面通过附图以及具体实施例对本发明技术方案做详细的说明, 应当理 解本发明实施例以及实施例中的具体特征是对本发明技术方案的详细的说 明, 而不是对本发明技术方案的限定, 在不冲突的情况下, 本发明实施例以 及实施例中的技术特征可以相互组合。
下面结合附图对本发明优选的实施方式进行详细说明。
本申请一实施例提供一种上行资源分配系统。 在实际应用中, 该系统可 以有且不限有两种系统架构。
第一种系统架构, 该系统可以为 UTMS系统。 该系统包括: 无线网絡控 制器(RNC, Radio Network Controller 宏基站。 其中, RNC用于下发测量 配置给用户设备; 还用于接收用户设备上报的测量报告, 并转发测量报告给 宏基站。 宏基站, 用于根据来自 RNC的测量报告, 将用户设备划分到笫一用 户设备组或者第二用户设备组, 其中, 第二用户设备组中的用户设备位于微 小区的边缘, 且不处于软切换区域, 且比第一用户设备組中的用户设备距离 宏基站远; 在调度周期内, 基于第一用户设备组内的用户设备数与第二用户 设备组内的用户设备数的比例, 分配上行数据传输子帧给第一用户设备組内 的用户设备和第二用户设备組内的用户设备。
第二种系统架构, 该可以为 LTE系统。 该系统包括宏基站。 其中, 宏基 站用于下发测量配置给用户设备; 还用于接收用户设备上报的测量报告, 并 根据来自用户设备的测量报告, 将用户设备划分到第一用户设备组或者第二 用户设备组, 其中, 第二用户设备组中的用户设备位于微小区的边缘, 且不 处于软切换区域, 且比第一用户设备组中的用户设备距离宏基站远; 在调度 周期内, 基于第一用户设备組内的用户设备数与第二用户设备组内的用户设 备数的比例, 分配上行数据传输子帧给第一用户设备組内的用户设备和第二 用户设备组内的用户设备。
当然, 在实际应用中还可有其他系统构架, 本申请不做具体限定。 需要 说明的是, 上述测量 ·ί艮告均为用户设备在其对应的微小区触发笫一同频测量 报告事件或第二同频测量报告事件时上报的, 如果没有触发上述同频测量报 告事件的话, 用户设备依旧可以周期性或事件触发性地上报其他测量事件的 测量报告, 此时, 宏基站将这些用户设备划分到第一用户设备组。
下面以 UTMS系统为例对上述系统的工作流程进行描述。
请参考图 1 , 首先, RNC向对于接入宏基站的上行用户设备, 即处于 CELL_DCH状态的用户设备, 发送测量配置, 在该测量配置中携带有 RNC 定义的两个同频测量 4艮告事件, 第一同频测量报告事件 Event laO和第二同频 测量报告事件 Event lb0。
其中, Event laO用于报告某用户设备由第一用户设备組转为第二用户设 备组, Event lbO用于报告某用户设备由第二用户设备组转为第一用户设备组。 这里所说的第二用户设备组中的用户设备比第一用户设备组中的用户设备距 离宏基站远, 且位于微小区的边缘, 且不处于软切换区域。
在具体实施过程中, 当 RNC下发测量报告之后, 可能所有用户设备对应 的微小区都没有触发新定义的同频测量报告事件 laO和 lbO, 所以, 宏基站在 收到用户设备第一次上报的有关 Event laO和 Event lbO的测量报告之前, 将 所有的用户设备划分到第一用户设备组。 然后, 用户设备根据上述测量配置 进行测量, 并向 RNC上报测量报告, 该测量报告中可以携带有触发上述同频 测量报告事件的同频测量报告事件信息, 如触发事件的标识, 以此来向 RNC 以及宏基站报告同频测量报告事件的触发结果。
可选的, 当与用户设备对应的微小区的导频信号变好时, 该微小区就触 发了用户设备的 Event laO, 当微小区的导频信号变差时, 该微小区就触发了 用户设备的 Event lbOo
可选的, 可以通过公共导频信道 (Common Pilot Channel, CPICH)的接收 信号码功率 (Received Signal Code Power , RSCP) , 或者 CPICH的每码片接收 能量除以带内的功率密度的值, 即 Eb/NO , 来表示导频信号的质量。 那么, 当 RSCP变大或者 Eb NO变大时,就表示导频信号变好,当 RSCP变小或者 Eb/NO 变小时, 就表示导频信号变差。
可选的, 当与用户设备对应的微小区的导频信号好到一定程度, 即满足 公式( 1 ) 时, 该微小区才触发用户设备的 Event la0。 其中, 公式( 1 )如下 所示:
10■ Log MNew + CIONew + PCO≥ W ·10. Log ∑Mt +(l-W).10-LogMBest -(Rla0 -Hla0 /2) ( 1 ) 相应的, 当与用户设备对应的微小区的导频信号差到一定程度, 即满足 公式(2 ) 时, 该微小区才触发用户设备的 Event lb0。 其中, 公式(2 )如下 所示:
Λ
10- Log MOId +CI0OId + PCO <W-10- Log ∑M; + (1 - W) · 10■ L^gMBest - (R,^ - Hlb0 / 2) ( 2 ) 其中, MNew是进入报告范围的微基站导频的测量结果; CIONw是进入报告 范围的微基站的特定偏移量( Individual Cell Offset ); E) 是用于判别高干扰 用户的常数, 越小表示该用户设备对相应微基站干扰越大; 是激活集小区 导频的测量结果; NA是当前激活集中包含的小区数目; MBst是激活集中信号 最强小区的导频信号测量结果; W是 RNC发送给用户设备的权重系数; 。是 报告范围常数; Hla。是对于 Event laO的回差值; 。是报告范围常数, 且数值 上 。 = 。; HlbQ是对于事件 lbO的回差值。
那么, 如杲微小区 A触发了用户设备的 Event laO, 则用户设备的测量才艮 告中就会携带微小区 ID=a以及第一同频测量报告事件信息 Event=la0, 对应 的, 如果微小区 A触发了用户设备的 Event lbO , 则用户设备的测量报告中就 会携带微小区 ID=a以及第二同频测量报告事件信息 Event=lb0。
接下来, RNC在接收到上述测量报告后, 通过 Iub接口将测量报告转发 给宏基站。
可选的, 为了避免微小区一直触发第一同频测量报告事件或第二同频测 量报告事件, 无线网络控制器在接收到上述测量报告后, 还可以根据测量报 告, 向报告了第一同频测量报告事件的用户设备通知在触发其第一同频测量 报告事件的微小区触发该用户设备的笫二同频测量报告事件之前, 此微小区 不再触发该用户设备的第一同频测量报告事件, 其他微小区仍可触发其第一 同频测量报告, 以及向报告了第二同频测量报告事件的用户设备通过在触发 其第二同频测量报告事件的微小区触发该用户设备的第一同频测量报告事件 之前, 此微小区不再触发该用户设备的第二同频测量报告事件, 其它微小区 仍可触发其第二同频测量报告事件。
例如, 微小区 a触发了用户设备 A的 Event laO , 那么, 在微小区 a触发 用户设备 A的 Event IbO之前是不能够再次触发用户设备 A的 Event laO的, 只有在微小区 a触发用户设备 A的 Event IbO之后,微小区 a才能够重新触发 用户设备 A的 Event la0。 同样的, 微小区 b触发了用户设备 A的 Event IbO, 其中,当刚开始进行测量配置时,微小区不能触发 Event IbO,只有触发过 Event laO的微小区才能触发相应的 Event IbO, 那么, 在微小区 b触发用户设备 A 的 Event laO之前是不能够再次触发用户设备 A的 Event IbO的, 只有在微小 区 b触发用户设备 A的 Event laO之后 ,微小区 b才能够重新触发用户设备 A 的 Event lbO, 不同 小区之间的事件触发相互独立, 互不影响。
进一步, 宏基站根据来自 RNC的测量报告, 将用户设备划分到第一用户 设备组或者第二用户设备组。
可选的, 若用户设备上报的测量报告是触发笫一同频测量报告事件上报 的, 如测量报告中携带有微小区标识以及第一同频测量报告事件信息
Event=la0, 则宏基站将该用户设备划分到第二用户设备组; 或者, 若用户设 备上报的测量报告是触发第二同频测量报告事件触发上报的, 如测量报告中 携带有微小区标识以及第二同频测量报告事件信息 Event=lb0, 那么, 宏基站 将用户设备进行测量之前所对应的微小区数与触发第二同频测量报告事件的 微小区数进行比较, 当用户设备进行测量之前所对应的微小区数大于触发第 二同频测量报告事件的微小区数时, 宏基站将用户设备划分到第二用户设备 组; 当用户设备进行测量之前所对应的微小区数等于触发第二同频测量报告 事件的微小区数时, 宏基站将用户设备划分到第一用户设备組。
例如, 用户设备 A在上报测量报告之前处于微小区 a和 b的边缘, 且为 这两个小区的高干扰用户设备, 即用户设备 A与微小区 a和 b对应, 那么, 如果宏基站接收到用户设备 A上报的测量报告中携带第二同频测量 4艮告事件 信息 Event=lb0的只有微小区 a, 也就是说, 用户设备 A为微小区 a的普通用 户设备, 但是仍为微小区 b的高千扰用户数设备, 即用户设备 A进行测量之 前所对应的微小区数大于触发第二同频测量报告事件的微小区数, 此时, 宏 基站仍将用户设备 A划分到第二用户设备组; 如果宏基站接收到用户设备 A 上报的测量报告中携带第二同频测量报告事件信息 Event=lb0的有微小区 a 和微小区 b, 也就是说, 用户设备 A为微小区 a和微小区 b的普通用户设备, 即用户设备 A进行测量之前所对应的^ L小区数等于触发第二同频测量 ^艮告事 件的微小区数, 此时, 宏基站仍将用户设备 A划分到第一用户设备組。
最后, 当调度周期来临时, 在调度周期内, 宏基站基于第一用户设备組 内的用户设备数与第二用户设备组内的用户设备数的比例, 分配上行数据传 输子帧给笫一用户设备组内的用户设备和第二用户设备组内的用户设备。
例如, 宏基站共有 N个上行数据传输子帧, 第一用户设备组内的用户设 备数: 第二用户设备组内的用户设备数 =k: 1 , 那么, 宏基站就将 IN个上
k + 1 行数据传输子帧分配给第一用户设备组内的用户设备,将 1 N个上行数据传
k + 1
输子帧分配给第二用户设备組内的用户设备, N为正整数, k大于等于 0。
在上行资源分配之后, 宏基站按照一定调度规则, 如轮训调度, 调度第 一用户设备组和第二用户设备组中的用户设备。 进一步, 在宏基站将用户设备分成两个大组, 即第一用户设备组和第二 用户设备组之后, 由于宏基站覆盖范围内可能出现多个微小区, 那么, 宏基 站根据第二用户设备組中的每个用户设备上报的测量报告, 分别确定出每个 用户设备对应的微小区, 其中, 每个用户设备处于一个或多个微小区的边缘; 根据每个用户设备对应的微小区, 分別将每个用户设备划分到第二用户设备 组中对应的小组, 其中, 每个用户设备对应的微小区与小组中的每个小组是 对应的。
可选的, 第二用户设备组中的用户设备至少位于一个微小区的边缘, 那 么, 宏基站根据第二用户设备组中的用户设备上报的微基站, 能够确定每个 用户设备所处在哪个微小区的边缘, 则这一个或者多个微小区即为与该用户 设备对应的微小区。 然后, 宏基站可以根据每个用户设备对应微小区再将第 二用户设备组分成小組。
可选的, 上述小組可以是实现宏基站就已经根据覆盖范围内的微小区个 数划分好的, 也可以是根据用户设备测量报告动态生成的, 本申请不做具体 限定。
在本实施例中, 上述划分小組的流程可以存在且不限于以下两种情况。 第一种, 在第二用户设备组中可能存在每个用户设备都只对应一个微小 区, 那么, 宏基站根据每个用户设备对应的微小区, 分别将每个用户设备划 分到第二用户设备組中与每个用户设备对应的微小区——对应的普通小组 中。 例如, 在第二用户设备組中, 用户设备 1处于微小区 a的边缘, 用户设 备 2处于微小区 b的边缘, 用户设备 3同时处于微小区 a的边缘, 用户设备 4 处于微小区 c的边缘, 那么, 宏基站将用户设备 1和用户设备 3划分到微小 区 a对应的普通小組 a中, 用户设备 2划分到微小区 b对应的普通小组 b中 , 将用户设备 4划分到微小区 c对应的普通小组 c中。
第二种, 若第二用户设备组中的任一用户设备仅处于单个微小区的边缘, 则宏基站将任一用户设备划分到第二用户设备组中与单个微小区一一对应的 普通小组; 若任一用户设备处于至少两个微小区的边缘, 宏基站则将任一用 户设备划分到与上述至少两个微小区对应的特定小組, 特定小组为普通小組 以外的一个小组。
例如, 在第二用户设备組中, 用户设备 1处于微小区 a的边缘, 用户设 备 2处于微小区 b的边缘, 用户设备 3同时处于微小区 c、 f的边缘, 用户设 备 4处于微小区 d、 f的边缘, 那么, 宏基站将用户设备 1划分到微小区 a对 应的普通小组 a中, 用户设备 2划分到微小区 b对应的普通小组 b中, 而将 用户设备 3划分到与微小区 c和 f对应的特定小组 cf中, 将用户设备 4划分 到与微小区 d和 f对应的特定小组 df中。
在实际应用中, 还可以存在其他分組策略, 本申请不做具体限定。
进一步, 在宏基站完成小组的划分之后, 为了优化分组, 在上述第二种 情况下, 若上述特定小组中仅包含一个用户设备, 宏基站将特定小组中的用 户设备划分到至少两个微小区中任一微小区所对应的普通小组中, 并删除特 定小组。
例如, 在宏基站划分完所有用户设备和小组之后, 如杲特定小组 cf中仅 包含同时处于微小区 c和微小区 f边缘的用户设备 3 , 那么, 宏基站就将用户 设备 3划分到微小区 c对应的普通小组 c中或者微小区 f对应的普通小組 f中, 然后删除特定小组 cf。
在上述第一种和 /或第二种情况下, 在宏基站完成小组的划分之后, 为了 优化分组, 宏基站还可以在将用户设备划分到笫二用户设备组中的普通小組 之后, 若普通小组中存在仅包含一个用户设备的单元小组, 将单元小组中的 用户设备划分到第一用户设备组中, 并删除单元小組。
例如, 在宏基站划分完所有用户设备和小组之后, 如果普通小组 a中仅 包含用户设备 1 , 那么, 普通小组 a就为单元小组, 宏基站就将该小组中的用 户设备 1划分到笫一用户设备組中, 然后删除普通小組 a。
至此, 宏基站就完成了对用户设备的小組划分。
接下来, 宏基站给各个小組分配上行数据传输子帧。
具体来说, 在宏基站给第二用户设备組分配上行数据传输子帧之后, 根 据第二用户设备组的各小组的用户设备数与第二用户设备组内的用户设备数 的比例, 将分配给第二用户设备組的上行数据传输子帧分配给第二用户设备 組的各小组内的用户设备。 其中, 宏基站可以将上行数据传输子帧分为普通 子帧和高干扰子帧, 在宏基站完成分组之后, 宏基站确定普通子帧及高干扰 子帧的图样, 如设定为每个调度周期内前一段子帧为高干扰子帧, 后一段子 帧为普通子帧, 并将普通子帧及高干扰子帧的比例及图样通过 Iub接口发给 RNC, RNC再将该比例及图样通过 Iub接口发送给相应的微基站。
例如, 之前宏基站分配 X个上行数据传输子帧给第二用户设备組内的 Y 个用户设备, 第二用户设备組中普通小组 a包含 S个用户设备, 那么, 宏基 站就将 NS 个上行数据传输子帧分配给普通小组 a内的用户设备。

进一步, 在上行资源分配之后, 宏基站可以按照预设的调度规则, 在相 应的上行数据传输子帧上对各个分组内的用户设备进行调度。

请参考图 4, 该方法包括:
S401 : 宏基站获取用户设备上报的测量报告;
S402: 宏基站根据用户设备上报的测量报告, 将用户设备划分到笫一用 户设备组或者第二用户设备組, 其中, 第二用户设备組中的用户设备位于微 小区的边缘, 且不处于软切换区域, 且比第一用户设备组中的用户设备距离 宏基站远;
S403: 宏基站在调度周期内, 基于第一用户设备組内的用户设备数与第 二用户设备组内的用户设备数的比例, 分配上行数据传输子帧给第一用户设 备组内的用户设备和第二用户设备组内的用户设备。
在本实施例中, 针对 UTMS系统, S401具体为: 宏基站向用户设备下发 测量配置; 宏基站接收由用户设备基于测量配置进行测量并上报的测量报告。
针对 LTE系统, S401具体包括: 宏基站接收由 RNC转发的用户设备的 测量报告, 其中, 测量报告是由用户设备根据 RNC下发的测量配置进行测量 并上报给 RNC的。
需要说明的是, 上述测量报告是用户设备根据测量配置进行测量并上报 的, 测量配置中携带有第一同频测量报告事件信息和第二同频测量报告事件 信息; 其中, 当与用户设备相关的微小区的导频信号变好时, 微小区触发第 一同频测量报告事件, 当第一微小区的导频信号变差时, 微小区触发第二同 频测量报告事件。
较优的, 当与用户设备对应的微小区的导频信号好到一定程度, 即满足 公式( 1 )时, 该微小区才触发用户设备的 Event laO, 相应的, 当与用户设备 对应的微小区的导频信号差到一定程度, 即满足公式(2 ) 时, 该微小区才触 发用户设备的 Event lbOo 可选的, 为了避免微小区一直触发 Event laO或 IbO, RNC或者宏基站在 接收到上述测量报告后, 还可以根据测量报告, 向报告了 Event laO的用户设 备通知在触发其 Event laO的微小区触发该用户设备的 Event IbO之前, 此微 小区不再触发该用户设备的 Event laO , 其他微小区仍可触发其 Event laO, 以 及向报告了 Event IbO的用户设备通过在触发其 Event IbO的微小区触发该用 户设备的 Event laO之前,此微小区不再触发该用户设备的 Event IbO,其它微 小区仍可触发其 Event lb0。
例如, 微小区 a触发了用户设备 A的 Event laO, 那么, 在微小区 a触发 用户设备 A的 Event IbO之前是不能够再次触发用户设备 A的 Event laO的, 只有在微小区 a触发用户设备 A的 Event IbO之后,微小区 a才能够重新触发 用户设备 A的 Event la0。 同样的, 微小区 b触发了用户设备 A的 Event IbO, 其中,当刚开始进行测量配置时,微小区不能触发 Event IbO,只有触发过 Event laO的微小区才能触发相应的 Event IbO , 那么, 在微小区 b触发用户设备 A 的 Event laO之前是不能够再次触发用户设备 A的 Event IbO的, 只有在微小 区 b触发用户设备 A的 Event laO之后,微小区 b才能够重新触发用户设备 A 的 Event lbO, 不同 小区之间的事件触发相互独立, 互不影响。
此时, S402具体可以为: 若用户设备上报的测量报告是触发第一同频测 量报告事件上报的, 宏基站将用户设备划分到第二用户设备組; 或, 若用户 设备上报的测量报告是触发第二同频测量报告事件上报的, 宏基站将用户设 备进行测量之前所对应的微小区数与触发第二同频测量报告事件的微小区数 进行比较, 其中, 当用户设备进行测量之前所对应的微小区数大于触发第二 同频测量报告事件的微小区数时, 宏基站将用户设备划分到第二用户设备组; 当用户设备进行测量之前所对应的微小区数等于触发第二同频测量报告事件 的微小区数时, 宏基站将用户设备划分到笫一用户设备组。
进一步, 在实际应用中, 还存在不处于微小区边缘的用户设备, 那么, 在 S401之前, 该方法还包括: 宏基站在接收用户设备上报测量报告之前, 将 用户设备划分到第一用户设备組。 S403 : 宏基站在调度周期内, 基于第一用户设备組内的用户设备数与第 二用户设备组内的用户设备数的比例, 分配上行数据传输子帧给第一用户设 备组内的用户设备和第二用户设备组内的用户设备。
在另一实施例中, 由于宏基站覆盖范围内可能出现多个微小区, 在 S402 之后, 且在 S403之前, 宏基站对第二用户设备组进行进一步的分组, 那么, 该方法还包括: 宏基站根据第二用户设备組中的每个用户设备上报的测量报 告, 分別确定出每个用户设备对应的微小区, 其中, 每个用户设备处于一个 或多个微小区的边缘; 宏基站根据每个用户设备对应的微小区, 分別将每个 用户设备划分到第二用户设备组中对应的小组, 其中, 每个用户设备对应的 微小区与小组中的每个小组——对应。
具体来说, 宏基站根据第二用户设备組中的每个用户设备上报的测量报 告, 分別确定出每个用户设备对应的微小区, 其中, 每个用户设备处于一个 或多个微小区的边缘; 根据每个用户设备对应的微小区, 分别将每个用户设 备划分到第二用户设备组中对应的小组, 其中, 每个用户设备对应的微小区 与小组中的每个小組是对应的。
具体来说, 第二用户设备組中的用户设备至少位于一个微小区的边缘, 那么, 宏基站根据第二用户设备组中的用户设备上报的微基站, 能够确定每 个用户设备所处在哪个微小区的边缘, 则这一个或者多个微小区即为与该用 户设备对应的微小区。 然后, 宏基站可以根据每个用户设备对应微小区再将 第二用户设备组分成小组。
需要说明的是, 在实际应用中, 上述小组可以是实现宏基站就已经根据 覆盖范围内的微小区个数划分好的, 也可以是根据用户设备测量报告动态生 成的, 本申请不做具体限定。
在本实施例中, 上述划分小组的流程可以存在且不限于以下两种情况。 第一种, 在第二用户设备組中可能存在每个用户设备都只对应一个微小 区, 那么, 宏基站根据每个用户设备对应的微小区, 分别将每个用户设备划 分到第二用户设备組中与每个用户设备对应的微小区一一对应的普通小组 中。
例如, 在第二用户设备組中, 用户设备 1处于微小区 a的边缘, 用户设 备 2处于微小区 b的边缘, 用户设备 3同时处于微小区 a的边缘, 用户设备 4 处于微小区 c的边缘, 那么, 宏基站将用户设备 1和用户设备 3划分到微小 区 a对应的普通小組 a中, 用户设备 2划分到微小区 b对应的普通小组 b中, 将用户设备 4划分到微小区 c对应的普通小組 c中。
第二种, 若第二用户设备组中的任一用户设备仅处于单个微小区的边缘, 则宏基站将任一用户设备划分到第二用户设备组中与单个微小区一一对应的 普通小组; 若任一用户设备处于至少两个微小区的边缘, 宏基站则将任一用 户设备划分到与至少两个微小区对应的特定小组, 特定小组为普通小组以外 的一个小组。
例如, 在第二用户设备組中, 用户设备 1处于微小区 a的边缘, 用户设 备 2处于微小区 b的边缘, 用户设备 3同时处于微小区 c、 f的边缘, 用户设 备 4处于微小区 d、 f的边缘, 那么, 宏基站将用户设备 1划分到微小区 a对 应的普通小组 a中, 用户设备 2划分到微小区 b对应的普通小组 b中, 而将 用户设备 3划分到与微小区 c、 f对应的特定小組 cf, 将用户设备 4划分到与 微小区 d、 f对应的特定小组 df中。
在实际应用中, 还可以存在其他分組策略, 本申请不做具体限定。
进一步, 在宏基站完成小组的划分之后, 为了优化分组, 在上述第二种 情况下, 若特定小組中仅包含一个用户设备, 宏基站将特定小组中的用户设 备划分到至少两个微小区中任一微小区所对应的普通小组中, 并删除特定小 組。
例如, 在宏基站划分完所有用户设备和小组之后, 如果特定小组 cf中仅 包含同时处于微小区 c和微小区 f边缘的用户设备 3 , 那么, 宏基站就将用户 设备 3划分到微小区 c对应的普通小组 c中或者微小区 f对应的普通小组 f中, 然后删除特定小组 cf。
在上述第一种和 /或第二种情况下, 在宏基站完成小组的划分之后, 为了 优化分组, 宏基站还可以在将用户设备划分到第二用户设备組中的普通小組 之后, 若普通小组中存在仅包含一个用户设备的单元小組, 将单元小组中的 用户设备划分到第一用户设备组中, 并删除单元小組。
例如, 在宏基站划分完所有用户设备和小组之后, 如杲普通小组 a中仅 包含用户设备 1 , 那么, 普通小组 a就为单元小組, 宏基站就将该小组中的用 户设备 1划分到第一用户设备組中, 然后删除普通小組 a。
至此, 宏基站就完成了对用户设备的小組划分。
接下来, 在执行 S403之后, 还需要进一步对于第二用户设备组中的各个 小组分配上行资源, 那么, 方法还包括: 宏基站根据第二用户设备组的各小 组的用户设备数与第二用户设备组内的用户设备数的比例 , 将分配给第二用 户设备组的上行数据传输子帧分配给第二用户设备組的各小組内的用户设 备。
前述实施例中的上行资源分配系统中的各种变化方式和具体实例同样适 用于本实施例的方法, 通过前述对上行资源分配系统的详细描述, 本领域技 术人员可以清楚的知道本实施例中方法的实施方法, 所以为了说明书的筒洁, 在此不再详述。
