为了使用户设备能够在同一个小区下的各位置组间平滑移动, 需要确保 用户设备在从一个位置组(位置组 A )移动至另一位置组(位置组 B ) 时所 采用的信道使用相同的时频资源以及相同的收发信机( TRX , Transceiver ) , 以使用户设备在同一小区的各位置组间移动不需要进行切换流程。
因此, 在为用户设备分配在通过位置组 A进行通信时使用的时频资源 时, 包括位置组 B在内的同一小区内的其他位置组中该时频资源也被占用。 或者说,如某用户设备在共小区位置组 A占用载频的某个时隙, 则其他位置 组中该载频的相同时隙需要保留, 即, 该用户设备在该小区内占用该时频资 源, 其他用户设备不能使用该时频资源。 从而降低了资源利用率。 发明内容

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。
本发明的技术方案, 可以应用于各种通信系统, 例如: 全球移动通讯系 统( GSM, Global System of Mobile communication ), 码分多址( CDMA, Code Division Multiple Access ) 系统, 宽带码分多址( WCDMA, Wideband Code Division Multiple Access Wireless ),通用分组无线业务 ( GPRS , General Packet Radio Service ), 长期演进( LTE, Long Term Evolution ), 通用移动通 信系统 ( UMTS , Universal Mobile Telecommunications System )等。
用户设备 ( UE , User Equipment ) , 也可称之为移动终端 ( Mobile Terminal ),移动用户设备等, 可以经无线接入网(例如, RAN, Radio Access Network )与一个或多个核心网进行通信, 用户设备可以是移动终端, 如移 动电话(或称为"蜂窝"电话)和具有移动终端的计算机, 例如, 可以是便携 式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置, 它们与无线接入 网交换语言和 /或数据。
图 1示出了从控制中心,例如,基站控制器(BSC, Base Station Controller ) 角度描述的是根据本发明实施例的资源调度的方法 100的流程, 以下, 为了 便于理解和说明, 以 BSC作为控制中心, 进行说明。 应理解, 以上列举的 作为控制器的 BSC仅为示例性说明, 本发明并不限定于此, 其他能够进行 资源调度的设备均落入本发明的保护范围内。 例如, 该控制中心也可以是集 成基站控制模块的演进型基站( eNB或 e-NodeB , evolutional Node B )等。
该方法 100可以在包括控制中心和至少两个位置组的通信系统中执行, 该至少两个位置组属于同一逻辑小区, 该至少两个位置组能够使用相同的时 频资源与相异的用户设备进行通信, 如图 1所示, 该方法 100包括:
S110,该控制中心从该至少两个位置组中确定为第一用户设备服务的至 少一个第一位置组;
S120, 该控制中心根据该第一位置组的可用时频资源进行资源调度, 以 仅使该第一位置组使用该第一位置组的可用时频资源中的第一时频资源与 该第一用户设备通信,该至少两个位置组中的至少一个第二位置组能够使用 该第一时频资源与第二用户设备通信。
具体地说,在本发明实施例中,可以将多个定向的站点改造为全向站点, 并进一步变为一个逻辑站点,原来的各站点的各个小区成为一个统一的逻辑 小区的不同的位置组, 各位置组可以相当于射频拉远模块 (RRU , Radio Remote Unit ), 由一个基带处理单元( BBU, Base Band Unite )管理, 从而, 能够进一步的增加共小区的复用度, 节省频率资源。 例如, 同一个站点(控 制中心, 例如, BSC ) 下的多个(例如, 三个)物理射频模块(以下, 称为 位置组)可以分属不同的物理地址, 但可以通过共小区技术, 使各位置组在 逻辑上属于同一个小区。 每个位置组的载频数、 频点、 信道配置、 全球小区 唯一标识(CGI, Cell of Grobal Identity )等小区级的参数配置为相同 (载波 的输出功率可以根据实际情况进行微调), 提高了整个小区的信号强度、 覆 盖范围以及通信质量,从而能够改善用户体验,降低整个小区使用的频率(原 来需要的是多个小区的频率)。 并且, 在本发明实施例中, 可以利用共小区 技术将一个传统配置定向小区的站点转变为全向站,原来的每个定向的扇区 相当于一个位置组。 从而可以适应农村等地域广阔、 人口稀疏、 话务量较低 的应用场景。 使用较少的频点实现较大的覆盖。 并且, 相对于传统的全向站 点, 采用了定向天线增益较全向天线高, 覆盖面积更广。 并且, 在例如将 GSM和 UMTS频率重新规划的情况下, 可以将多个(例如, 三个) GSM小 区合并为一个小区, 原来的每个 GSM小区相当于一个位置组, 节省出频点 给 UMTS使用, 从而使得运营商在无需新增频谱的前替下, 使得 GSM和 UMTS同时提供业务。
在本发明实施例中,可以利用共小区技术,将经上述改造的多个站点(或 者多个小区)统一为一个逻辑小区的不同位置组, 使各位置组采用相同的物 理配置、 载波数、 频点、 信道配置等小区参数。 并且, 可以预先对各位置组 进行同步, 使多个位置组的时间计数统一, 确保各位置组的空口发射的帧完 全同步, 其中, 作为同步的方式, 可以采用全球定位系统 (GPS , Global Positioning System )硬同步方式, 也可以采用软同步方式, 本发明并未特别 限定。
现有技术中, 对于一个目标用户设备(以下, 记做 UE1 )的资源(信道) 分配是以小区 (具体地说是上述包括多个位置组的逻辑小区) 为单位, 即, 如果 UE1 接入或者切换至本小区, 具体地说, 是接入或者切换至小区内的 一个位置组(记#文位置组 A, 即第一位置组的一例), 则会为该 UE1分配时 频资源 (包括时域资源和频域资源), 位置组 A可以利用该时频资源与 UE1 通信, 并且, 该 UE1在该小区内占用该时频资源, 即, 其他位置组(例如, 位置组 B , 即第二位置组的一例) 不能使用该时频资源与其他 UE (例如, UE2 )通信。
与此相对, 在本发明实施例中, 对于 UE1 的资源 (信道)分配是以位 置组为单位, 即, 如果 UE1接入或者切换至位置组 A, 则控制中心会为该 UE1分配在位置组 A中使用的时频资源(记^ ί故时频资源 X ), 位置组 Α可以 利用该时频资源 X与 UE1通信, 并且, 该 UE1在该小区内的其他位置组中 不占用该时频资源 X, 即, 位置组 B能够使用该时频资源 X与 UE2通信。 可选地, 该控制中心根据该第一位置组的可用时频资源进行资源调度, 包括:
该控制中心根据该第一位置组的可用时频资源进行资源调度, 以使第一 空域资源与第二空域资源的配置相同, 其中, 该第一空域资源是该第一位置 组与该第一用户设备通信之间的通信所使用的第一时频资源所对应的空域 资源, 该第二空域资源是该第二位置组与该第二用户设备之间的通信所使用 的第一时频资源所对应的空域资源。
具体地说, 在本发明实施例中, 第一空域资源与第二空域资源的配置可 以相同, 也可以相异, 即, 用于位置组 A与 UE1之间通信的时频资源 X与 用于位置组 B与 UE2之间通信的时频资源 X在空域上的配置(具体的说, 是所对应的空域资源, 例如, 所使用的收发信机、 天线角度等)可以是相同 的, 也可以使相异的, 本发明并未特别限定。 即, 在本发明实施例中, 位置 组 A与位置组 B 可以不采用空分复用的方式实现使用时频资源 X分别与 UE1和 UE2通信。
由于该至少两个位置组能够使用相同的时频资源与相异的用户设备进 行通信, 在一个位置组使用一个时频资源与一个用户设备通信的同时, 另一 个位置组能够使用同样的时频资源与另一个用户设备通信, 能够提高资源利 用率, 降低运营成本。
下面, 以 BSC针对接入其控制的逻辑小区内的一个位置组(例如, 位 置组 A ) 的 UE1 的资源调度为例, 对根据本发明实施例的资源调度的方法 100。
在 S110, BSC可以获取 UE1的位置信息, 从而确定 UE1的位置。
具体地说, BSC可以获取用于该 UE1的用户设备信息 (例如, 该手机 的手机号、 该手机的物理地址等), 从而可以根据该用户设备信息, 获取该 移动通信设备的位置, 从而确定该移动通信设备的位置为该用户的位置, 在 本发明实施例中, 可以使用例如基站定位法、 全球定位系统(GPS, Global Position System ) 定位法等通常的移动通信设备定位方法对移动通信设备进 行定位, 从而获取该移动通信设备的位置。
应理解, 以上列举的的作为移动通信设备的各实体以及用于指示该实体 的参数信息仅为本发明的一个实施例, 本发明并不限定于此, 该移动通信设 备可以经无线接入网(例如, RAN, Radio Access Network )与一个或多个核 心网进行通信,如移动电话(或称为 "蜂窝 "电话 )和具有移动终端的计算机, 例如, 可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置, 它们与无线接入网交换语言和 /或数据。
并且, 如果为该 UE1 提供通信服务的运营商能够为该移动通信设备提 供定位服务(例如,通过基站定位法进行定位或通过 GPS定位法进行定位), 则 BSC可以向该运营商发送该移动通信设备的设备信息 (例如, 手机号), 从而使该运营商通过该设备信息(例如, 手机号)确定该移动通信设备, 并 对其进行定位, 将指示该用的位置的用户位置信息发送 BSC。
这样, 通过从第三方系统(为该 UE1 提供通信服务的运营商)获取用 户位置信息, 能够减少对用户进行定位的时间, 提高用户体验。
并且, 在 UE1 自身具有定位功能(例如, 通过 GPS定位法进行定位) 的情况下, BSC可以根据该 UE1的设备信息(例如, 手机号), 直接对该移 动通信设备进行位置上报请求(例如, 以语音拨方式叫或短消息方式), 从 而使 UE1上报其当前所处的位置。
并且, 在本发明实施例中, BSC可以(例如, 通过运营商的通知, 或管 理员的配置 )获知其控制的各位置组的位置以及覆盖范围。
从而, 例如, 如果 UE1处于位置组 A的覆盖范围内, 则 BSC可以选择 位置组 A作为为该 UE1服务的位置组(第一位置组的一例;)。
应理解, 以上列举的确定第一位置组的方法仅为示例性说明, 本发明并 不限定于此, 例如, 还可以记录 UE1 的移动路径或移动范围, 选择两个或 两个以上位置组作为为该 UE1服务的位置组(第一位置组的另一例)。 再例 如, 在各位置组均能够与 UE1 通信的情况下, 也可以随机地选择一个或多 个位置组作为为该 UE1服务的位置组(第一位置组的再一例)。
在 S120, BSC可以从位置组 A的空闲时频资源 (可用时频资源) 中, 选择用于位置组 A与该 UE1之间的通信的时频资源 (即, 第一时频资源)。
在本发明实施例中, 时频资源包括时域资源和频域资源, 并且, 时域资 源可以包括一个时隙, 也可以包括多个时隙, 并且, 该多个时隙可以是连续 的时隙, 也可以是非连续时隙, 本发明并未特别限定。 同样, 频域资源可以 包括一个频点 (或者说载频), 也可以包括多个频点, 并且, 该多个频点可 以是连续的频点, 也可以是非连续频点, 本发明并未特别限定。 可选地, 该控制中心根据该第一位置组的可用时频资源进行资源调度, 以仅使该第一位置组使用该第一位置组的可用时频资源中的第一时频资源 与该第一用户设备通信, 包括:
该控制中心遍历该第一位置组中的至少一个收发信机 TRX的可用时隙 以及该至少一个时频资源的可用时隙, 以确定该第一时频资源以及用于与该 第一用户设备通信的第一 TRX,其中,该第一时频资源的可用时隙与该第一 TRX的可用时隙相同,该至少两个位置组能够使用至少一个频域资源进行通 信, 该至少两个位置组中的各位置组分别使用至少一个 TRX进行通信, 该 TRX在一个时隙能够使用该至少一个频域资源中的任一频域资源进行通信; 该控制中心指示该第一位置组使用该第一 TRX 以及该第一时频资源与 该第一用户设备通信。
具体地说, 在本发明实施例中, 各位置组可以通过一个或多个 TRX进 行通信(传输信号), 并且, 各 TRX均能够使用该小区使用的全部频域资源 (具体地说是全部频点) 中的任一频点传输信号。
并且, 在本发明实施例中, BSC可以遍历位置组 A上存在的空闲 TRX 时隙和空闲的时频资源, 当两者均为空闲, 即时频资源的空闲时隙(未被占 用的时隙)与 TRX的空闲时隙相同,则将两者匹配并 ^据该时频资源为 UE1 建立信道。 在本发明实施例中, 根据该空闲时频资源建立信道的方法和过程 可以与现有技术相似, 这里, 为了避免赘述, 省略其说明。 这里, 空闲时频 资源是指, 该时频资源(具体地说, 是该时频资源所对应的时隙和频点)未 被其他 UE占用, 并且, TRX的空闲时隙是指 TRX在该时隙无需发射信号。
需要说明的是, 在本发明实施例中, 时频资源的时隙与 TRX的时隙存 在对应关系, 即, 对于一个时频资源, 在 TRX中具有相对应的时隙。
并且, 在本发明实施例中 BSC还可以将所有符合要求的空闲 TRX时隙 和空闲的时频资源编为一个集合, 从而, 在进行针对其他 UE1在位置组 A 的资源调度时, 可以直接从该集合中选择适用的时频资源以及 TRX。
以上列举了 BSC针对接入位置组 A的 UE1的资源调度的方法和过程, 该方法和过程同样适用于 UE1从其他位置组切换至位置组 A的情况,这里, 为例避免赘述, 省略其说明。
可选地, 该控制中心根据该第一位置组的可用时频资源进行资源调度, 以仅使该第一位置组使用该第一位置组的可用时频资源中的第一时频资源 与该第一用户设备通信, 包括:
该控制中心确定该第一用户设备需要从该至少两个位置组中的第二位 置组切换至该第一位置组, 其中, 该第二位置组使用该第一时频资源与该第 一用户设备通信;

具体地说, 当 UE1从其他位置组(例如, 位置组 C )移动至位置组 A 时, BSC可以确定 UE1在位置组 C中使用的时频资源, 如果该时频资源在 位置组 A中为空闲时频资源, 并且, 该时频资源所对应的时隙与 TRX的空 闲时隙相同, 则 BSC可以将该时频资源作为 UE1在位置组 A中使用的时频 资源 (第一时频资源), 并且, BSC可以根据该第一时频资源的在位置组 C 中的配置(包括移动分配(MA, Mobile Allocation )集、 移动分配指针偏移 ( MAIO, Mobile Allocation Idex Offset ),调频序列号( HSN, Handoff Sequence Number )等), 确定该时频资源 (第一时频资源) 的在位置组 A中的配置, 以实现 UE1从位置组 C到位置组 A的平滑切换。
需要说明的是, 在本发明实施例中, 该控制中心根据该第一位置组的可 用时频资源进行资源调度, 以 "仅" 使该第一位置组使用第一时频资源与该 第一用户设备通信, 是指, 该第一时频资源为该第一用户设备在第一位置组 中使用的时频资源, 该第一用户设备并不在其他位置组中占用该第一时频资 源 (即, 时隙相同且频点相同的资源), 其他的位置组(第二位置组)可以 使用该第一时域资源与其他用户设备进行通信。 并且, 在该第二位置组中, 在例如, 使用空分复用等方式的情况下, 还可以使用该第一时域资源, 同时 与两个或两个以上的除该第一用户设备以外的用户设备进行通信。
即, 可选的, 该方法还包括:
该控制中心确定该第二位置组为该第二用户设备服务;
该控制中心进行资源调度, 以使该第二位置组使用该第一时频资源与该 第二用户设备通信。
具体地说, 在本发明实施例中, 当其他用户设备(例如, UE2 )需要接 入或切换至与该位置组 A相异的其他位置组(一个或多个位置组, 例如, 位 置组 B )时,如果该第一时域资源在位置组 B可用(或者说, 空闲 ), 则 BSC 可以使用该第一时域资源为该其他 UE2建立信道, 该过程与上述 BSC进行 的针对 UE1的处理相似, 这里, 为例避免赘述, 省略其说明。
根据本发明实施例的资源调度的方法,通过控制中心根据用户设备的位 置确定为该用户设备服务的位置组, 并确定该位置组使用的时频资源, 使其 他位置组的该时频资源不被该用户设备占用, 能够在一个位置组使用一个时 频资源与一个用户设备通信的同时, 另一个位置组能够使用同样的时频资源 与另一个用户设备通信, 因此从而能够不影响其他位置组对该时频资源的使 用, 能够提高资源利用率, 降低运营成本。
图 2示出了从用户设备角度描述的是根据本发明实施例的资源调度的方 法 200的流程。 该方法 200可以在包括控制中心、 至少两个位置组和用户设 备的通信系统中执行, 该至少两个位置组属于同一逻辑小区, 该方法包括: S210, 该用户设备确定第一时频资源, 该第一时频资源是该控制中心根 据该至少一个第一位置组的可用时频资源进行资源调度而分配的;
S220,该用户设备使用第一时频资源与该控制中心从该至少两个位置组 中确定的至少一个第一位置组通信, 其中, 该至少两个位置组中的至少一个 第二位置组能够使用该第一时频资源与第二用户设备通信。
具体地说,在本发明实施例中,可以将多个定向的站点改造为全向站点, 并进一步变为一个逻辑站点,原来的各站点的各个小区成为一个统一的逻辑 小区的不同的位置组, 各位置组可以相当于射频拉远模块 (RRU, Radio Remote Unit ), 由一个基带处理单元( BBU, Base Band Unite )管理, 从而, 能够进一步的增加共小区的复用度, 节省频率资源。 例如, 同一个站点(控 制中心, 例如, BSC ) 下的多个(例如, 三个)物理射频模块(以下, 称为 位置组)可以分属不同的物理地址, 但可以通过共小区技术, 使各位置组在 逻辑上属于同一个小区。 每个位置组的载频数、 频点、 信道配置、 全球小区 唯一标识(CGI, Cell of Grobal Identity )等小区级的参数配置为相同 (载波 的输出功率可以根据实际情况进行微调), 提高了整个小区的信号强度、 覆 盖范围以及通信质量,从而能够改善用户体验,降低整个小区使用的频率(原 来需要的是多个小区的频率)。 并且, 在本发明实施例中, 可以利用共小区 技术将一个传统配置定向小区的站点转变为全向站,原来的每个定向的扇区 相当于一个位置组。 从而可以适应农村等地域广阔、 人口稀疏、 话务量较低 的应用场景。 使用较少的频点实现较大的覆盖。 并且, 相对于传统的全向站 点, 采用了定向天线增益较全向天线高, 覆盖面积更广。 并且, 在例如将
GSM和 UMTS频率重新规划的情况下, 可以将多个(例如, 三个) GSM小 区合并为一个小区, 原来的每个 GSM小区相当于一个位置组, 节省出频点 给 UMTS使用, 从而使得运营商在无需新增频谱的前替下, 使得 GSM和 UMTS同时提供业务。
在本发明实施例中,可以利用共小区技术,将经上述改造的多个站点(或 者多个小区)统一为一个逻辑小区的不同位置组, 使各位置组采用相同的物 理配置、 载波数、 频点、 信道配置等小区参数。 并且, 可以预先对各位置组 进行同步, 使多个位置组的时间计数统一, 确保各位置组的空口发射的帧完 全同步, 其中, 作为同步的方式, 可以采用全球定位系统 (GPS , Global Positioning System )硬同步方式, 也可以采用软同步方式, 本发明并未特别 限定。
现有技术中, 对于一个目标用户设备(以下, 记做 UE1 )的资源(信道) 分配是以小区 (具体地说是上述包括多个位置组的逻辑小区) 为单位, 即, 如果 UE1 接入或者切换至本小区, 具体地说, 是接入或者切换至小区内的 一个位置组(记#文位置组 A, 即第一位置组的一例), 则会为该 UE1分配时 频资源 (包括时域资源和频域资源), 位置组 A可以利用该时频资源与 UE1 通信, 并且, 该 UE1在该小区内占用该时频资源, 即, 其他位置组(例如, 位置组 B, 即第二位置组的一例) 不能使用该时频资源与其他 UE (例如, UE2 )通信。
与此相对, 在本发明实施例中, 对于 UE1 的资源 (信道)分配是以位 置组为单位, 即, 如果 UE1接入或者切换至位置组 A, 则控制中心会为该 UE1分配在位置组 A中使用的时频资源(记^ ί故时频资源 X ) , 位置组 Α可以 利用该时频资源 X与 UE1通信, 并且, 该 UE1在该小区内的其他位置组中 不占用该时频资源 X, 即, 位置组 B能够使用该时频资源 X与 UE2通信。
可选地, 第一空域资源与第二空域资源的配置相同, 其中, 该第一空域 资源是该至少一个第一位置组与该第一用户设备通信之间的通信所使用的 第一时频资源所对应的空域资源, 该第二空域资源是该至少一个第二位置组 与该第二用户设备之间的通信所使用的第一时频资源所对应的空域资源。 具体地说, 在本发明实施例中, 第一空域资源与第二空域资源的配置可 以相同, 也可以相异, 即, 用于位置组 A与 UE1之间通信的时频资源 X与 用于位置组 B与 UE2之间通信的时频资源 X在空域上的配置(具体的说, 是所对应的空域资源, 例如, 所使用的收发信机、 天线角度等)可以是相同 的, 也可以使相异的, 本发明并未特别限定。 即, 在本发明实施例中, 位置 组 A与位置组 B 可以不采用空分复用的方式实现使用时频资源 X分别与 UE1和 UE2通信。
由于该至少两个位置组能够使用相同的时频资源与相异的用户设备进 行通信, 在一个位置组使用一个时频资源与一个用户设备通信的同时, 另一 个位置组能够使用同样的时频资源与另一个用户设备通信, 能够提高资源利 用率, 降低运营成本。
下面, 以 BSC针对接入其控制的逻辑小区内的一个位置组(例如, 位 置组 A ) 的 UE1 的资源调度为例, 对根据本发明实施例的资源调度的方法 100。
BSC可以获取 UE1的位置信息, 从而确定 UE1的位置。
具体地说, BSC可以获取用于该 UE1的用户设备信息 (例如, 该手机 的手机号、 该手机的物理地址等), 从而可以根据该用户设备信息, 获取该 移动通信设备的位置, 从而确定该移动通信设备的位置为该用户的位置, 在 本发明实施例中, 可以使用例如基站定位法、 全球定位系统(GPS, Global Position System ) 定位法等通常的移动通信设备定位方法对移动通信设备进 行定位, 从而获取该移动通信设备的位置。
应理解, 以上列举的的作为移动通信设备的各实体以及用于指示该实体 的参数信息仅为本发明的一个实施例, 本发明并不限定于此, 该移动通信设 备可以经无线接入网(例如, RAN, Radio Access Network )与一个或多个核 心网进行通信,如移动电话(或称为 "蜂窝 "电话 )和具有移动终端的计算机, 例如, 可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置, 它们与无线接入网交换语言和 /或数据。
并且, 如果为该 UE1 提供通信服务的运营商能够为该移动通信设备提 供定位服务(例如,通过基站定位法进行定位或通过 GPS定位法进行定位), 则 BSC可以向该运营商发送该移动通信设备的设备信息 (例如, 手机号), 从而使该运营商通过该设备信息(例如, 手机号)确定该移动通信设备, 并 对其进行定位, 将指示该用的位置的用户位置信息发送 BSC。
这样, 通过从第三方系统(为该 UE1 提供通信服务的运营商)获取用 户位置信息, 能够减少对用户进行定位的时间, 提高用户体验。
并且, 在 UE1 自身具有定位功能(例如, 通过 GPS定位法进行定位) 的情况下, BSC可以根据该 UE1的设备信息(例如, 手机号), 直接对该移 动通信设备进行位置上报请求(例如, 以语音拨方式叫或短消息方式), 从 而使 UE1上报其当前所处的位置。
并且, 在本发明实施例中, BSC可以(例如, 通过运营商的通知, 或管 理员的配置 )获知其控制的各位置组的位置以及覆盖范围。
从而, 例如, 如果 UE1处于位置组 A的覆盖范围内, 则 BSC可以选择 位置组 A作为为该 UE1服务的位置组(第一位置组的一例;)。
应理解, 以上列举的确定第一位置组的方法仅为示例性说明, 本发明并 不限定于此, 例如, 还可以记录 UE1 的移动路径或移动范围, 选择两个或 两个以上位置组作为为该 UE1服务的位置组(第一位置组的另一例)。 再例 如, 在各位置组均能够与 UE1 通信的情况下, 也可以随机地选择一个或多 个位置组作为为该 UE1服务的位置组(第一位置组的再一例)。
BSC可以从位置组 A的空闲时频资源 (可用时频资源) 中, 选择用于 位置组 A与该 UE1之间的通信的时频资源 (即, 第一时频资源)。
在本发明实施例中, 时频资源包括时域资源和频域资源, 并且, 时域资 源可以包括一个时隙, 也可以包括多个时隙, 并且, 该多个时隙可以是连续 的时隙, 也可以是非连续时隙, 本发明并未特别限定。 同样, 频域资源可以 包括一个频点 (或者说载频), 也可以包括多个频点, 并且, 该多个频点可 以是连续的频点, 也可以是非连续频点, 本发明并未特别限定。
可选地, 该第一时频资源是该控制中心遍历该至少一个第一位置组中的 至少一个收发信机 TRX的可用时隙以及该至少一个时频资源的可用时隙后 确定的, 其中, 该第一时频资源的可用时隙与第一 TRX的可用时隙相同, 该第一 TRX用于该至少一个第一位置组与该用户设备的通信, 该至少两个 位置组能够使用至少一个频域资源进行通信,该至少两个位置组中的各位置 组分别使用至少一个 TRX进行通信, 该 TRX在一个时隙能够使用该至少一 个频域资源中的任一频域资源进行通信。。
具体地说, 在本发明实施例中, 各位置组可以通过一个或多个 TRX进 行通信(传输信号), 并且, 各 TRX均能够使用该小区使用的全部频域资源 (具体地说是全部频点) 中的任一频点传输信号。
并且, 在本发明实施例中, BSC可以遍历位置组 A上存在的空闲 TRX 时隙和空闲的时频资源, 当两者均为空闲, 即时频资源的空闲时隙(未被占 用的时隙)与 TRX的空闲时隙相同,则将两者匹配并 ^据该时频资源为 UE1 建立信道。 在本发明实施例中, 根据该空闲时频资源建立信道的方法和过程 可以与现有技术相似, 这里, 为了避免赘述, 省略其说明。 这里, 空闲时频 资源是指, 该时频资源(具体地说, 是该时频资源所对应的时隙和频点)未 被其他 UE占用, 并且, TRX的空闲时隙是指 TRX在该时隙无需发射信号。
需要说明的是, 在本发明实施例中, 时频资源的时隙与 TRX的时隙存 在对应关系, 即, 对于一个时频资源, 在 TRX中具有相对应的时隙。
并且, 在本发明实施例中 BSC还可以将所有符合要求的空闲 TRX时隙 和空闲的时频资源编为一个集合, 从而, 在进行针对其他 UE1在位置组 A 的资源调度时, 可以直接从该集合中选择适用的时频资源以及 TRX。
以上列举了 BSC针对接入位置组 A的 UE1的资源调度的方法和过程, 该方法和过程同样适用于 UE1从其他位置组切换至位置组 A的情况,这里, 为例避免赘述, 省略其说明。
可选地,该第一时频资源是该控制中心确定该第一用户设备需要从该至 少一个第二位置组切换至该至少一个第一位置组后,根据该至少一个第二位 置组中该第一时频资源的配置而确定的, 其中, 该至少一个第二位置组使用 该第一时频资源与该第一用户设备通信, 该第一时频资源属于该至少一个第 一位置组的可用时频资源。
具体地说, 当 UE1从其他位置组(例如, 位置组 C )移动至位置组 A 时, BSC可以确定 UE1在位置组 C中使用的时频资源, 如果该时频资源在 位置组 A中为空闲时频资源, 并且, 该时频资源所对应的时隙与 TRX的空 闲时隙相同, 则 BSC可以将该时频资源作为 UE1在位置组 A中使用的时频 资源 (第一时频资源), 并且, BSC可以根据该第一时频资源的在位置组 C 中的配置(包括移动分配(MA, Mobile Allocation )集、 移动分配指针偏移 ( MAIO, Mobile Allocation Idex Offset ),调频序列号( HSN, Handoff Sequence Number )等), 确定该时频资源 (第一时频资源) 的在位置组 A中的配置, 以实现 UE1从位置组 C到位置组 A的平滑切换。 需要说明的是, 在本发明实施例中, 该控制中心可以根据该第一位置组 的可用时频资源进行资源调度, 以 "仅" 使该第一位置组使用第一时频资源 与该第一用户设备通信, 具体地说, 该第一时频资源为该第一用户设备在第 一位置组中使用的时频资源, 该第一用户设备并不在其他位置组中占用该第 一时频资源 (即, 时隙相同且频点相同的资源), 其他的位置组(第二位置 组)可以使用该第一时域资源与其他用户设备进行通信。 并且, 在该第二位 置组中, 在例如, 使用空分复用等方式的情况下, 还可以使用该第一时域资 源, 同时与两个或两个以上的除该第一用户设备以外的用户设备进行通信。
并且, 在本发明实施例中, 当其他用户设备(例如, UE2 )需要接入或 切换至与该位置组 A相异的其他位置组(一个或多个位置组, 例如, 位置组 B ) 时, 如果该第一时域资源在位置组 B可用 (或者说, 空闲), 则 BSC可 以使用该第一时域资源为该其他 UE2建立信道, 该过程与上述 BSC进行的 针对 UE1的处理相似, 这里, 为例避免赘述, 省略其说明。
从而, 在 S210, UE1可以确定该第一时频资源, 并在 S220, 通过该第 一时频资源与位置组 A进行通信。
可选地, 该用户设备确定第一时频资源包括:
该用户设备接收该控制中心经由该第一位置组发送的资源指示信息, 该 资源指示信息用于指示该第一时频资源;
才艮据该资源指示信息, 确定该第一时频资源。
具体地说, 在本发明实施例中, 控制中心可以通过资源调度, 通知位置 组 A该第一时频资源, 从而位置组 A可以直接通过该第一时频资源向 UE1 传输下行数据, 从而, UE1可以确定该第一时频资源, 或者, 位置组 A可 以向 UE1发送指示信息, 以通知该第一时频资源, 从而, UE1可以通过该 第一时频资源, 向位置组 A发送上行数据。
根据本发明实施例的资源调度的方法,通过控制中心根据用户设备的位 置确定为该用户设备服务的位置组, 并确定该位置组使用的时频资源, 使其 他位置组的该时频资源不被该用户设备占用, 能够在一个位置组使用一个时 频资源与一个用户设备通信的同时, 另一个位置组能够使用同样的时频资源 与另一个用户设备通信, 因此从而能够不影响其他位置组对该时频资源的使 用, 能够提高资源利用率, 降低运营成本。
