本发明实施例提供一种资源确定方法, 该方法为多制式网络控 制器侧的方法, 如图 1所示, 该方法包括以下内容。
S 101、 多制式网络控制器获取第二小区对第一小区的干扰关系 信息, 所述干扰关系信息用于指示所述第二小区在时频上对第一小 区的干扰, 所述第二小区与所述第一小区具有不同的制式。
本发明实施例中, 所述第二小区与所述第一小区具有不同的制 式, 例如, 这些制式可以包括 GSM制式、 CDMA制式、 TDMA制式、 WCDMA 制式、 FDMA制式、 0FDMA制式、 SC-FDMA制式、 GPRS制式、 LTE制式, 以 及其他此类通信系统制式等。 第一小区和第二小区可以在同一通信系 统下具有不同的制式 (例如, 同一多制式基站下的两个不同制式的 小区 ), 可以是不同制式通信系统下的两个小区。
本发明实施例中第一小区与第二小区可以共享无线频谱资源, 也就是, 第一小区与第二小区均使用相同频段内的时频资源进行业 务。 具体地, 以第一小区的制式为 LTE制式, 第二小区的制式为 GSM 制 式为 例 , 在 某种场 景 下 , 第 一 小 区 与 第 二 小 区 均使用 800MHz-810MHz的无线频语资源进行业务, 由于在 GSM制式与在 LTE 制式比较下, 小区在 GSM 制式下的发射功率较高, 一个载波的发射 功率约为 20 瓦特 ( W)。 而 LTE 系统的发射功率较低, 一个物理资源 ( Physical Resource Block, PRB )的发射功率约为 0.8W/180kHz。 当第一小区与第二小区共享无线频谱资源时, 第二小区将严重干扰 到第一小区, 多制式网络控制器可以获取第二小区对第一小区的干 扰关系信息,该干扰关系信息用于指示第一小区在哪些时频资源(例 如, 哪些 PRB或时隙上) 上受到第二小区的干 4尤。
可选地, 在本发明实施例的资源确定方法, 多制式网络控制器 获取第二小区对第一小区的干扰关系信息的方法具体包括: 获取网 络规划数据或路测数据, 所述网络规划数据包括所述第一小区的位 置信息和所述第二小区的位置信息, 所述路测数据包括所述第一小 区内的路测终端接收所述第二小区的信号强度; 并根据所述网络规 划数据或路测数据确定所述干扰关系信息; 或者, 获取所述第二小 区的信号强度和所述第二小区的载波配置信息, 并根据所述信号强 度及所述载波配置信息确定所述干扰关系信息。
需要说明的是, 本发明实施例中, "时频" 是指时间和 /或频率, 相应地, 时频资源指时隙资源或频率资源
S102、 多制式网络控制器根据所述干扰关系信息, 确定所述第 二小区的时频资源信息, 所述第二小区的时频资源信息用于所述第 二小区进行时频资源分配。
进一步地, 多制式网络控制器根据所述干扰关系信息, 确定所 述第二小区的时频资源信息, 包括: 若接收到所述第二小区发送的 时频资源分配请求, 多制式网络控制器根据所述干扰关系信息分配 所述第二小区的时频资源信息。 可选地, 该时频资源分配请求可以 为载波分配请求信息或时隙分配请求信息。
具体地, 随着第二小区的业务的变化, 例如, 新用户的业务请 求, 第二小区会发送时频资源分配请求信息至多制式网络控制器, 使得多制式网络控制器可以根据获取的第二小区对第一小区的干扰 关系信息, 确定第二小区的时频资源信息。 第二小区可以根据多制 式网络控制器确定的第二小区的时频资源信息进行时频资源分配以 避免或减少第二小区对第一小区的干扰。 例如第二小区在发起该业 务时, 可以选择不会对第一小区产生干扰的载波或不调度可能对第 一小区产生干扰的 RB或时隙。
本发明实施例中的多制式网络控制器可以为一个独立的网络服 务器, 也可以是第一小区的接入网设备 (例如基站或基站控制器) 或核心网设备, 也可以是第二小区的接入网络设备或核心网设备, 也可以既不是第一小区的接入网设备或核心网设备也不是第二小区 的接入网设备或核心网设备。
本领域技术人员可以理解的是, 以 GSM为例, 一个载波上的每 个时分多址 ( Time Division Multiple Access , TDMA ) 帧包含 8个 时隙 ( 分别为 s 1010、 s 1011…… s 1017 ) , 每个时隙长度可以为 0.557ms。 由此可知, 载波分配请求信息是用于请求多制式网络控制 器为第二小区分配所使用的载波的, 时隙分配请求信息相对于载波 分配请求信息而言更加细化, 即用于请求多制式网络控制器为第二 小区分配载波中的时隙的。
进而, 多制式网络控制器在接收到第二小区发送的时频资源分 配请求信息后, 多制式网络控制器根据所述干扰关系信息, 确定所 述第二小区的时频资源信息。 具体地, 多制式网络控制器根据所述 干扰关系信息, 确定所述第二小区的时频资源信息的方法包括: 多 制式网络控制器根据所述干扰关系信息, 对齐所述第二小区与第一 小区的时频资源, 进而生成所述第二小区的时频资源信息, 所述第 二小区的时频资源包括时间资源和 /或频率资源。
进一步地, 所述方法还包括: 多制式网络控制器根据所述干扰 关系信息, 确定所述第一小区的时频资源信息, 所述第一小区的时 频资源信息用于所述第一小区进行时频资源分配分配。
进一步地, 多制式网络控制器在确定第一小区的时频资源信息 之后, 所述方法还包括: 多制式网络控制器向所述第一小区发送所 述第一小区的时频资源信息, 以使所述第一小区根据所述第一小区 的时频资源信息进行时频资源分配。 其中, 所述第一小区的时频资源信息包括所述第二小区干扰所 述第一小区的时频资源的干扰程度信息。 所述第一小区根据所述第 一小区的时频资源信息进行时频资源分配包括: 所述第一小区根据 所述第一小区的时频资源信息, 确定不调度所述第一小区的时频资 源信息指示的时频资源或基于干扰程度信息进行调制编码机制 MCS 降阶调度所述第一小区的时频资源信息指示的时频资源, 即所述第 一小区的时频资源信息包括用于指示避免调度的时频资源或用于指 示所述第一小 区在时频上进行调制编码机制 ( Modulation and Coding Scheme, MCS ) MCS降阶调度的时频资源的信息。
进一步地, 在 S102之前, 所述方法还可以包括: 接收所述第二 小区发送的所述第二小区所占用的时隙的发射功率信息。那么, S102 具体包括根据所述干扰关系信息及所述第二小区所占用的时隙的发 射功率信息, 确定所述第二小区的时频资源信息。
进一步地, 多制式网络控制器在确定第二小区的时频资源信息 后, 多制式网络控制器向所述第二小区发送所述第二小区的时频资 源信息, 以使所述第二小区根据所述第二小区的时频资源信息进行 时频资源分配。 由上述实施例可知, 第二小区向多制式网络控制器 发送的时频资源分配请求可以为载波分配请求信息或时隙分配请求 信息, 那么, 多制式网络控制器向所述第二小区发送与时频资源分 配请求对应的所述第二小区的时频资源信息也可以包括载波配置方 式或时隙配置方式, 进而, 所述第二小区根据所述载波配置方式或 时隙配置方式进行载波配置或时隙配置。
本发明实施例提供一种资源确定方法, 多制式网络控制器通过 获取第二小区对第一小区的干扰关系信息, 所述干扰关系信息用于 指示所述第二小区在时频上对第一小区的干扰, 所述第二小区与所 述第一小区具有不同的制式, 以及根据所述干扰关系信息, 确定所 述第二小区的时频资源信息, 所述第二小区的时频资源信息用于所 述第二小区进行时频资源分配。 通过该方案, 由于获取了干扰小区 ( 即第二小区 ) 对被干扰小区 ( 即第一小区 ) 的干扰关系信息, 并 根据该干扰关系信息确定了干扰小区的时频资源信息, 因此, 干扰 小区根据该时频资源信息进行时频资源分配后, 能够降低干扰小区 对被干扰小区的干扰。
本发明实施例还提供一种资源确定方法, 该方法为第一小区侧 的方法, 如图 2所示, 该方法包括以下内容。
S 2 01、 第一小区获取第一小区的时频资源信息, 所述第一小区 的时频资源信息用于所述第一小区进行时频资源分配。
作为本发明实施例的一种实施方式, 第一小区获取第一小区的 时频资源信息的方法具体可以包括:
接收多制式网络控制器发送的所述第一小区的时频资源信息; 其中, 所述第一小区的时频资源信息为所述多制式网络控制器获取 第二小区对所述第一小区的干扰关系信息, 并根据所述干扰关系信 息, 确定所述第一小区的时频资源信息后, 所述多制式网络控制器 发送至所述第一小区的, 所述干扰关系信息用于指示所述第二小区 在时频上对第一小区的干扰, 所述第二小区与所述第一小区具有不 同的制式。
作为本发明实施例的另一种实施方式, 第一小区获取第一小区 的时频资源信息的方法具体可以包括:
获取第二小区对第一小区的干扰关系信息, 所述干扰关系信息 用于指示所述第二小区在时频上对第一小区的干扰, 所述第二小区 与所述第一小区具有不同的制式; 根据所述第一小区的干扰关系信 息, 确定所述第一小区的时频资源信息。
S 2 02、 第一小区根据所述第一小区的时频资源信息进行时频资 源分配。
其中, 根据所述第一小区的时频资源信息进行时频资源分配, 包括: 根据所述第一小区的时频资源信息, 使用所述第一小区的第 一载波对所述第一小区的第二载波进行配置, 其中, 所述第二载波 包括所述第一小区与所述第二小区共享的时频资源。
本领域技术人员可以理解的是, 在时域上, 第一小区的物理下 行控制信道 ( Physical Downlink Control Channel , PDCCH ) 一般 占用每个时隙 lms 的前三个正交频分复用 ( Orthogonal Frequency Division Multiplexing, OFDM ) 符号。 在频域上, PDCCH—般占用 所有带宽。 例如, 第一小区占用 10MHz, 则 50个 PRB上都有 PDCCH。 因此即使通过调度错开了物理下行共享信道 ( Physical Down 1 ink Shared Channel , PDSCH )在 PRB4上受到的强干扰,也无法错开 PDCCH 在 PRB4上受到的强干扰。 所以为了避免 PDCCH受到第二小区的强干 扰, 可以釆用的方法是釆用跨载波调度。 即假设第一小区工作在多 载波模式,同时占用载波 1及载波 2,其中,可以利用载波 1 的 PDCCH 来分配载波 2 的 PDSCH, 也就是说, 载波 2可以没有 PDCCH。 也就是 上述所描述的第一小区使用所述第一小区的第一载波对所述第一小 区的第二载波进行分配。
本发明实施例提供一种资源确定方法, 第一小区获取第一小区 的时频资源信息, 所述第一小区的时频资源信息用于所述第一小区 进行时频资源分配, 根据所述第一小区的时频资源信息进行时频资 源分配。 通过该方案, 由于获取了第一小区的时频资源信息, 第一 小区的时频资源是根据干扰小区 ( 即第二小区 ) 对被干扰小区 ( 即 第一小区 ) 的干扰关系信息所确定的, 因此, 被干扰小区根据该时 频资源信息进行时频资源分配后, 能够降低干扰小区对被干扰小区 的干扰。
本发明实施例还提供一种资源确定方法, 该方法为第二小区侧 的方法, 如图 3所示, 该方法包括以下内容。
S301、 第二小区获取第二小区的时频资源信息, 所述第二小区 的时频资源信息为多制式网络控制器或第一小区获取所述第二小区 对第一小区的干扰关系信息后, 根据所述干扰关系信息确定的, 所 述干扰关系信息用于指示所述第二小区在时频上对第一小区的干 扰, 所述第二小区与所述第一小区具有不同的制式。
其中, 在 S 301之前, 所述方法可以还包括: 向所述多制式网络 控制器或所述第一小区发送时频资源分配请求, 所述时频资源请求 用于指示所述所述多制式网络控制器或所述第一小区为所述第二小 区分配所述第二小区的时频资源信息。
S 302、 第二小区根据所述第二小区的时频资源信息进行时频资 源分配。
本发明实施例提供一种资源确定方法, 第二小区获取第二小区 的时频资源信息, 所述第二小区的时频资源信息为多制式网络控制 器或第一小区获取所述第二小区对第一小区的干扰关系信息后, 根 据所述干扰关系信息确定的, 所述干扰关系信息用于指示所述第二 小区在时频上对第一小区的干扰, 所述第二小区与所述第一小区具 有不同的制式, 根据所述第二小区的时频资源信息进行时频资源分 配。 通过该方案, 由于第二获取了第二小区的时频资源信息, 第二 小区的时频资源是根据干扰小区 ( 即第二小区 ) 对被干扰小区 ( 即 第一小区 ) 的干扰关系信息所确定的, 因此, 干扰小区根据该时频 资源信息进行时频资源分配后, 能够降低干扰小区对被干扰小区的 干扰。
实施例二
本发明实施例提供一种资源确定方法, 如图 4 所示, 以第一小 区的系统为 LTE 系统、 第二小区的系统为 GSM为例进行详细描述, 该方法包括以下内容。
S401、 多制式网络控制器获取第二小区对第一小区的干扰关系 信息, 所述干扰关系信息用于指示所述第二小区在时频上对第一小 区的干扰。
根据第三代合作伙伴计划 ( The 3rd Generation Partnership Project, 3GPP ) 标准对无线电通信频段的定义, 900MHz和 1800MHz 频段主要用于 GSM。 随着第三代移动通信技术 ( 3rd-generation, 3G ) 业务的逐步普及和用户的迁移, 且 3G 业务主要承载在 2. 1GHz 频段, 因此, GSM 的 GSM900 和 GSM1800 频段的负荷逐渐减轻。 GSM 的 GSM900和 GSM1800频段的无线频语资源便可以逐步应用于更先进 且效率更高的 LTE 网络, 即 GSM与 LTE 系统之间实现共享频谱资源。 此时,由于 GSM的发射功率很高,一个载波的发射功率约为 20W, 而 LTE网络的发射功率较低,一个 PRB的发射功率约为 0. 8W/180kHz, 因此, 当第一小区与第二小区共享频谱资源时, 第二小区将严重干 扰第一小区, 该问题导致的结果可能是, 该第一小区与第二小区都 无法进行业务。 本发明实施例提供的资源确定方法, 目 的即是降低 共享无线频谱资源的不同制式的系统之间的同频干扰。
需要指出的是, 本发明实施例中, LTE 系统小区 (第一小区 ) 可能全部共享 GSM的无线频谱资源, 并且, 由于 GSM 系统小区的发 射功率远通常大于 LTE 系统小区, 因此 GSM 系统小区会对 LTE 系统 小区产生的严重的干扰。
具体地, S401 中多制式网络控制器获取第二小区对第一小区的 干扰关系信息的方法至少包括以下一种或两种。
如图 5所示, 第一种方法具体包括以下内容。
S501、 多制式网络控制器获取网络规划数据或路测数据。
其中, 所述网络规划数据具体可以包括所述第一小区的位置信 息和第二小区的位置信息, 所述路测数据具体可以包括所述第一小 区内的路测终端接收所述第二小区的信号强度。
S502、 多制式网络控制器根据所述网络规划数据或路测数据确 定所述干扰关系信息。
如图 6所示, 第二种方法具体包括以下内容。
S 601、 多制式网络控制器获取所述第二小区的信号强度。
其中, 多制式网络控制器获取所述第二小区的信号强度的方法 至少包括以下一种或两种:
( 1 )多制式网络控制器接收所述第一小区发送的第二小区的信 号强度, 其中, 所述第二小区的信号强度为所述第一小区向第一用 户设备发送第一测量指示后, 所述第一用户设备返回所述第一测量 指示对应的所述第二小区的信号强度至所述第一小区的。
需要指出的是, 该方案中的第一用户设备的服务小区为所述第 一小区, 第二小区为所述第一用户设备的非服务小区, 但第一用户 设备处于第二小区的覆盖范围内, 第一用户设备能够监听获得所述 第二小区的信号强度。
( 2 )多制式网络控制器接收所述第二小区发送的所述第二小区 的信号强度, 其中, 所述第二小区的信号强度为所述第二小区向第 二用户设备发送第二测量指示后, 所述第二用户设备返回所述第二 测量指示对应的所述第二小区的信号强度至所述第二小区的。
需要指出的是, 该方案能够执行的条件为第一小区与第二小区 共站, 这是由于, 若第一小区与第二小区共站, 则第一小区与第二 小区可以共同利用铁搭, 天馈等设施, 节约了投资与维护成本。 其 中, 本领域技术人员可以理解的是, "共站" 是指地理位置相同、 共 铁塔。
S602、 多制式网络控制器接收所述第二小区发送的载波配置信 息及载波功率配置信息。
其中, 所述载波配置信息包括所述第二小区配置的载波, 所述 载波功率配置信息包括所述第二小区配置的载波的发射功率。
S603、 多制式网络控制器根据所述信号强度、 所述载波配置信 息以及所述载波功率配置信息, 确定所述干扰关系信息。
举例来说, 如图 7所示, 为 GSM与 LTE 系统共享无线频谱资源 的干扰关系结构图, 假设 GSM与 LTE 同频的频谱资源有 1号区域、 4 号区域、 7号区域、 10号区域、 13号区域、 16号区域、 19号区域、 22号区域、 27号区域、 34号区域、 37号区域、 40号区域、 43号区 域、 46号区域及 47号区域, 那么以第一小区所使用的频谱资源为 1 号区域为例, 根据上述获取干扰关系信息的各种方法, 多制式网络 控制器确定第一小区除了受同频 LTE 小区干扰, 还受到同频 GSM 小 区不同强度的干扰, 其强干扰的有 {1 号区域 } , 其对应的信号强度 为 [- 30dBm, -70dBm]; 次强干扰的有 {4号区域, 7号区域, 10号区 域, 13号区域, 16号区域, 19号区域, 22号区域 } , 其对应的信号 强度为 [_85dBm, -95dBm]; 弱干扰的有 { 27号区域, 34号区域, 37 号区域, 40号区域, 43号区域, 46号区域, 47号区域 } , 其对应的 信号强度为 [-lOOdBm, _110dBm]。
进一步地, 多制式网络控制器还可以接收到第二小区的载波配 置信息及载波功率配置信息, 例如, 第二小区配置有载波 f0、 f3及 f6, 其中 fO为用于信号测量的载波, f0、 f3及 f6 的发射功率均为 20W, 那么多制式网络控制器就能够通过所述载波配置信息以及所述 载波功率配置信息, 确定所述干扰关系信息, 例如, 第二小区在载 波 f0、 f 3及 f 6 上对第一小区的信号强度为 [_30dBm, -70dBm] , 或 者, 考虑发射功率为 43dBm, 第二小区在载波 f0、 f3 及 f6 上到第 一小区的路损为 [_73dB, _113dB]。
综上所述, 多制式网络控制器可以根据所述信号强度、 所述载 波配置信息以及所述载波功率配置信息, 确定所述干扰关系信息。 所述干扰关系信息包括所述第二小区对所述第一小区的干扰强度信 息, 或所述第二小区到第一小区的路损信息。
S402、 多制式网络控制器接收所述第二小区的发送的所述第二 小区所占用的时隙的发射功率信息。
与上述示例对应的, 第二小区可以将包括 "第二小区的载波 fO 上, 时隙 ( s lot ) 0对应的发射功率为 20W, slotl对应的发射功率 为 10W, slot2对应的发射功率为 1W, 其它 slot没有分配, 对应的 发射功率为 0" 的所述第二小区所占用的时隙的发射功率信息发送 至多制式网络控制器, 以使得后续步骤中多制式网络控制器能够更 精准地确定第二小区的时频资源信息和第一小区的时频资源信息。 因此, 需要补充说明的是 S402为可选步骤。
S403、 多制式网络控制器接收所述第二小区发送的时频资源分 配请求信息。
其中, 随着第二小区的业务的变化, 如, 新用户的业务请求, 第二小区会发送时频资源分配请求信息至多制式网络控制器。
例如, 第二小区分配的载波为 f0、 f3 及 f6, 当前用户使用了 fO, 而其它载波上没有业务, 现在有新用户的业务请求, 需要占用 新的载波, 第二小区则会发送该时频资源分配请求信息至多制式网 络控制器。
具体地, 该时频资源分配请求可以为载波分配请求信息或时隙 分配请求信息。 载波分配请求信息是用于请求多制式网络控制器为 第二小区分配载波的, 时隙分配请求信息相对于载波分配请求信息 而言更加细化, 即用于请求多制式网络控制器为第二小区分配载波 中的时隙的。
S 4 04、 多制式网络控制器根据所述干扰关系信息及所述第二小 区所占用的时隙的发射功率信息, 确定所述第二小区的时频资源信 息。
其中, 多制式网络控制器根据所述干扰关系信息及所述第二小 区所占用的时隙的发射功率信息, 确定所述第二小区的时频资源信 息具体包括: 根据所述干扰关系信息及所述第二小区所占用的时隙 的发射功率信息, 对齐所述第二小区与第一小区的时频资源, 进而 生成所述第二小区的时频资源信息, 所述第二小区的时频资源包括 时间资源和 /或频率资源。
下面, 对多制式网络控制器如何根据干扰关系信息中的不同信 息, 确定所述第二小区的时频资源信息的方法进行详细描述。
( 1 )多制式网络控制器根据干扰关系信息中的第二小区的信号 强度, 确定所述第二小区的时频资源信息。
具体地, 与上述示例相对应, 第二小区的载波包括时间和频率, 第一小区的 PRB 也包括时间和频率, 对齐第二小区的载波与第一小 区的 PRB 的时频资源后, 多制式网络控制器根据干扰关系中第一小 区对受到 G SM 的不同程度的干扰, 多制式网络控制器确定 LTE 的第 一小区的 PRB 4 上受 G SM 的干扰较大 (对齐后对应 f 3 ) , PRB 7 上受 GSM的干扰较小 (对齐后对应 f 6 ) , 则为了空出 f 6给 LTE制式的第 一小区, 多制式网络控制器决定令 G SM选择 f 3集中干扰。 本发明实 施例中的对齐, 是指时间或频率的帧的起始位置对齐。
( 2 )多制式网络控制器根据干扰关系信息中的第二小区到第一 小区的路损信息, 确定所述第二小区的时频资源信息。 与上述示例相对应, 例如, 第二小区在载波 f0、 f3及 f6上对 第一小区的信号强度为 [_30dBm, -70dBm] , 或者, 考虑发射功率为 43dBm,第二小区在载波 f 0、 f 3及 f 6上到第一小区的路损为 [_73dB, -113dB],此时,如果路损信息表明第二小区到第一小区的路损很大, 说明第二小区对第一小区的干扰很小, 那么可以第二小区可以使用 整个时频资源。
进一步地, 干扰关系信息中还可以包括第二小区的信号到达第 一小区的强度, 故多制式网络控制器如何根据干扰关系信息中的不 同信息, 确定所述第二小区的时频资源信息的方法进一步包括:
( 3 )多制式网络控制器根据干扰关系信息中的第二小区的信号 到达第一小区的强度, 确定所述第二小区的时频资源信息。
其中, 第二小区的信号到达第一小区的强度表明第二小区对第 一小区的干扰大小, 如果第二小区对第一小区的干扰很小, 那么可 以第二小区可以使用整个时频资源, 或干扰关系信息包括第二小区 的信号对第一小区信号的相对干扰强度, 如果第二小区对第一小区 的相对干扰强度很小, 那么可以第二小区可以使用整个时频资源。
进一步地, 若多制式网络控制器根据干扰关系信息及所述第二 小区所占用的时隙的发射功率信息, 确定所述第二小区的时频资源 信息, 则多制式网络控制器在确定第二小区的时频资源信息时, 可 以确定所述第二小区所占用的时隙对第一小区相应时频资源的干扰 强度, 若所述第二小区所占用的时隙对第一小区相应时频资源干扰 很强, 那么把该资源标识为强干扰资源。
S 405、 多制式网络控制器根据所述干扰关系信息及所述第二小 区所占用的时隙的发射功率信息, 确定第一小区的时频资源信息。
其中, 所述第一小区的时频资源信息包括所述第二小区干扰所 述第一小区的时频资源的干扰程度信息。
需要说明的是, S404 与 S405 之间没有时间顺序的限制, 即可 以先执行 S404, 再执行 S405, 也可以先执行 S405, 再执行 S404, 还可以同时执行 S404和 S405, 本发明不做限制。 S406、 多制式网络控制器向所述第二小区发送所述第二小区的 时频资源信息, 以使所述第二小区根据所述第二小区的时频资源信 息进行时频资源分配。
S407、 多制式网络控制器向所述第一小区发送所述第一小区的 时频资源信息, 以使所述第一小区根据所述第一小区的时频资源信 息进行时频资源分配。
与上述示例相对应,多制式网络控制器将载波 f 3的时频资源信 息发送给第二小区, 以使第二小区根据该时频资源信息进行时频资 源分配; 多制式网络控制器将可使用资源 PRB7 的资源信息或不可使 用资源 PRB4 的资源信息发送给第一小区, 以使第一小区根据该资源 信息调度可使用资源 PRB7, 或避免调度不可使用资源 PRB4, 或 MCS 降阶调度不可使用资源 PRB4。
进一步地, 所述第一小区还可以根据所述第一小区的时频资源 信息, 使用所述第一小区的第一载波对所述第一小区的第二载波进 行配置, 其中, 所述第二载波为所述第一小区与所述第二小区共享 的时频资源。
具体地, 在时域上, 第一小区的物理下行控制信道 ( Physical Downlink Control Channel , PDCCH ) 一般占用每个时隙 lms 的前三 个正交频分复用 ( Orthogonal Frequency Division Multiplexing, OFDM ) 符号。 在频域上, PDCCH —般占用所有带宽。 例如, 第一小 区占用 10MHz, 则 50个 PRB上都有 PDCCH。 因此即使通过调度错开 了物理下行共享信道 ( Physical Downlink Shared Channel , PDSCH ) 在 PRB4 上受到的强干扰, 也无法错开 PDCCH在 PRB4 上受到的强干 扰。 所以为了避免 PDCCH 受到第二小区的强干扰, 可以釆用的方法 是釆用跨载波调度。 即假设第一小区工作在多载波模式, 同时占用 载波 1 及载波 2, 其中, 可以利用载波 1 的 PDCCH 来分配载波 1 的 PDSCH, 也就是说, 载波 2可以没有 PDCCH。 也就是上述所描述的第 一小区使用所述第一小区的第一载波对所述第一小区的第二载波进 行配置。 需要说明的是, S406 与 S407 之间没有时间顺序的限制, 即可 以先执行 S406, 再执行 S407, 也可以先执行 S407, 再执行 S406, 还可以同时执行 S406和 S407, 本发明不做限制。
本发明实施例提供一种资源确定方法, 多制式网络控制器通过 获取第二小区对第一小区的干扰关系信息, 所述干扰关系信息用于 指示所述第二小区在时频上对第一小区的干扰, 所述第二小区与所 述第一小区具有不同的制式, 以及根据所述干扰关系信息, 确定所 述第二小区的时频资源信息, 所述第二小区的时频资源信息用于所 述第二小区进行时频资源分配。 通过该方案, 由于获取了干扰小区 ( 即第二小区 ) 对被干扰小区 ( 即第一小区 ) 的干扰关系信息, 并 根据该干扰关系信息确定了干扰小区的时频资源信息, 因此, 干扰 小区根据该时频资源信息进行时频资源分配后, 能够降低干扰小区 对被干扰小区的干扰。
实施例三
本发明实施例一种资源确定方法, 如图 8 所示, 以第一小区的 系统为 LTE、 第二小区的系统为 GSM 为例进行详细描述, 该方法包 括以下内容。
S701、 第一小区获取第二小区对第一小区的干扰关系信息, 所 述干扰关系信息用于指示所述第二小区在时频上对第一小区的干 扰。
根据 3GPP 标准对无线电通信频段的定义, 900MHz 和 1800MHz 频段主要用于 GSM。 随着 3G 业务的逐步普及和用户的迁移, 且 3G 业务主要承载在 2.1GHz 频段, 因此, GSM 的 GSM900和 GSM1800频 段的负荷逐渐减轻。 GSM的 GSM900和 GSM1800频段的无线频语资源 便可以逐步应用于更先进且效率更高的 LTE 网络, 即 GSM与 LTE 系 统之间实现共享频谱资源。
此时,由于 GSM的发射功率很高,一个载波的发射功率约为 20W, 而 LTE网络的发射功率较低,一个 PRB的发射功率约为 0.8W/180kHz, 因此, 当第一小区与第二小区共享频谱资源时, 第二小区将严重干 扰第一小区, 该问题导致的结果可能是, 该第一小区与第二小区都 无法进行业务。 本发明实施例提供的资源确定方法, 目 的即是降低 共享无线频谱资源的不同制式的系统之间的同频干扰。
需要指出的是, 本发明实施例中, 所述第一小区全部共享 GSM 的无线频谱资源, 并且, 由于 GSM的发射功率远大于 LTE 系统, 因 此 GSM对 LTE 系统的干扰是主要因素, 本发明实施例暂不讨论 LTE 系统对 GSM的干 ·ί尤。
具体地, S701 中第一小区获取第二小区对第一小区的干扰关系 信息的方法至少包括以下一种或两种。
如图 9所示, 第一种方法具体包括以下内容。
S801、 第一小区获取网络规划数据或路测数据。
其中, 所述网络规划数据具体可以包括所述第一小区的位置信 息和第二小区的位置信息, 所述路测数据具体可以包括所述第一小 区内的路测终端接收所述第二小区的信号强度。
S802、 第一小区根据所述网络规划数据或路测数据确定所述干 扰关系信息。
如图 10所示, 第二种方法具体包括以下内容。
S901、 第一小区获取所述第二小区的信号强度。
其中, 第一小区获取所述第二小区的信号强度的方法至少包括 以下一种或两种:
( 1 )所述第一小区向第一用户设备发送第一测量指示; 所述第 一用户设备返回所述第一测量指示对应的所述第二小区的信号强度 至所述第一小区。
需要指出的是, 该方案中的第一用户设备的服务小区为所述第 一小区, 第二小区为所述第一用户设备的非服务小区, 但第一用户 设备处于第二小区的覆盖范围内, 第一用户设备能够监听获得所述 第二小区的信号强度。
( 2 )第一小区接收所述第二小区发送的所述第二小区的信号强 度, 其中, 所述第二小区的信号强度为所述第二小区向第二用户设 备发送第二测量指示后, 所述第二用户设备返回所述第二测量指示 对应的所述第二小区的信号强度至所述第二小区的。
需要指出的是, 该方案能够执行的条件为第一小区与第二小区 共站, 这是由于, 若第一小区与第二小区共站, 则第一小区与第二 小区可以共同利用铁搭, 天馈等设施, 节约了投资与维护成本。
S902、 第一小区接收所述第二小区发送的载波配置信息及载波 功率配置信息。
其中, 所述载波配置信息包括所述第二小区配置的载波, 所述 载波功率配置信息包括所述第二小区配置的载波的发射功率。
S903、 第一小区根据所述信号强度、 所述载波配置信息以及所 述载波功率配置信息, 确定所述干扰关系信息。
仍以图 7为例, 假设 GSM与 LTE 同频的频谱资源有 1号区域、 4 号区域、 7号区域、 10号区域、 13号区域、 16号区域、 19号区域、 22号区域、 27号区域、 34号区域、 37号区域、 40号区域、 43号区 域、 46 号区域及 47 号区域, 那么以 LTE 的第一小区所使用的频语 资源为 1 号区域为例, 根据上述获取干扰关系信息的各种方法, 第 一小区确定 LTE 的第一小区除了受同频 LTE 小区干扰, 还受到同频 GSM小区不同强度的干扰, 其强干扰的有 {1 号区域 } , 其对应的信号 强度为 [_30dBm, -70dBm]; 次强干扰的有 {4 号区域, 7 号区域, 10 号区域, 13号区域, 16号区域, 19号区域, 22号区域 } , 其对应的 信号强度为 [_85dBm, -95dBm]; 弱干扰的有 { 27号区域, 34号区域, 37 号区域, 40 号区域, 43 号区域, 46 号区域, 47 号区域 } , 其对 应的信号强度为 [-lOOdBm, _110dBm] 。
进一步地, 第一小区还可以接收到第二小区的载波配置信息及 载波功率配置信息, 例如, 第二小区配置有载波 f0、 f 3 及 f6, 其 中 f0为用于信号测量的载波, f0、 f 3及 f6 的发射功率均为 20W, 那么第一小区就能够通过所述载波配置信息以及所述载波功率配置 信息, 确定所述干扰关系信息, 例如, 第二小区在载波 f0、 f 3 及 f6上对第一小区的信号强度为 [_30dBm, -70dBm] , 或者, 考虑发射 功率为 43dBm, 第二小区在载波 f0、 f 3 及 f 6 上到第一小区的路损 为 [_73dB, -113dB]。
综上所述, 第一小区可以根据所述信号强度、 所述载波配置信 息以及所述载波功率配置信息, 确定所述干扰关系信息。 所述干扰 关系信息包括所述第二小区对所述第一小区的干扰强度信息, 或所 述第二小区到第一小区的路损信息。
S702、 第一小区接收所述第二小区的发送的所述第二小区所占 用的时隙的发射功率信息。
与上述示例对应的, 第二小区可以将包括 "第二小区的载波 fO 上, 时隙 ( s lot ) 0对应的发射功率为 20W, slotl对应的发射功率 为 10W, slot2对应的发射功率为 1W, 其它 slot没有分配, 对应的 发射功率为 0" 的所述第二小区所占用的时隙的发射功率信息发送 至第一小区, 以使得后续步骤中第一小区能够更精准地确定第二小 区的时频资源信息和第一小区的时频资源信息。 因此, 需要补充说 明的是 S702为可选步骤。
S703、 第一小区接收所述第二小区发送的时频资源分配请求信 息。
其中, 随着第二小区的业务的变化, 如, 新用户的业务请求, 第二小区会发送时频资源分配请求信息至第一小区。
例如, 第二小区分配的载波为 f0、 f3 及 f6, 当前用户使用了 fO, 而其它载波上没有业务, 现在有新用户的业务请求, 需要占用 新的载波, 第二小区则会发送该时频资源分配请求信息至第一小区。
具体地, 该时频资源分配请求可以为载波分配请求信息或时隙 分配请求信息。 载波分配请求信息是用于请求第一小区为第二小区 分配载波的, 时隙分配请求信息相对于载波分配请求信息而言更加 细化, 即用于请求第一小区为第二小区分配载波中的时隙的。
S704、 第一小区根据所述干扰关系信息及所述第二小区所占用 的时隙的发射功率信息, 确定所述第二小区的时频资源信息。
其中, 第一小区根据所述干扰关系信息及所述第二小区所占用 的时隙的发射功率信息, 确定所述第二小区的时频资源信息具体包 括: 根据所述干扰关系信息及所述第二小区所占用的时隙的发射功 率信息, 对齐所述第二小区与第一小区的时频资源, 进而生成所述 第二小区的时频资源信息, 所述第二小区的时频资源包括时间资源 和 /或频率资源。
下面, 对第一小区如何根据干扰关系信息中的不同信息, 确定 所述第二小区的时频资源信息的方法进行详细描述。
( 1 )第一小区根据干扰关系信息中的第二小区的信号强度, 确 定所述第二小区的时频资源信息。
具体地, 与上述示例相对应, 第二小区的载波包括时间和频率, 第一小区的 PRB 也包括时间和频率, 对齐第二小区的载波与第一小 区的 PRB 的时频资源后, 第一小区根据干扰关系中 LTE 的第一小区 对受到 GSM的不同程度的干扰,第一小区确定 LTE的第一小区的 PRB4 上受 GSM的干扰较大 (对齐后对应 f 3 ), PRB7上受 GSM的干扰较小 (对齐后对应 f 6 ), 则为了腾出 f6给 LTE的第一小区, 第一小区决 定令 GSM选择 f 3集中干扰。
( 2 )第一小区根据干扰关系信息中的第二小区到第一小区的路 损信息, 确定所述第二小区的时频资源信息。
与上述示例相对应, 例如, 第二小区在载波 f0、 f3及 f6上对 第一小区的信号强度为 [_30dBm, -70dBm] , 或者, 考虑发射功率为 43dBm,第二小区在载波 f 0、 f 3及 f 6上到第一小区的路损为 [_73dB, -113dB],此时,如果路损信息表明第二小区到第一小区的路损很大, 说明第二小区对第一小区的干扰很小, 那么可以第二小区可以使用 整个时频资源。
进一步地, 干扰关系信息中还可以包括第二小区的信号到达第 一小区的强度, 故第一小区如何根据干扰关系信息中的不同信息, 确定所述第二小区的时频资源信息的方法进一步包括:
( 3 )根据干扰关系信息中的第二小区的信号到达第一小区的强 度, 确定所述第二小区的时频资源信息。 其中, 第二小区的信号到达第一小区的强度表明第二小区对第 一小区的干扰大小, 如果第二小区对第一小区的干扰很小, 那么可 以第二小区可以使用整个时频资源, 或干扰关系信息包括第二小区 的信号对第一小区信号的相对干扰强度, 如果第二小区对第一小区 的相对干扰强度很小, 那么可以第二小区可以使用整个时频资源。
进一步地, 若第一小区根据干扰关系信息及所述第二小区所占 用的时隙的发射功率信息, 确定所述第二小区的时频资源信息, 则 第一小区在确定第二小区的时频资源信息时, 可以确定所述第二小 区所占用的时隙对第一小区相应时频资源的干扰强度, 若所述第二 小区所占用的时隙对第一小区相应时频资源干扰很强, 那么把该资 源标识为强干扰资源。
S705、 第一小区根据所述干扰关系信息及所述第二小区所占用 的时隙的发射功率信息, 确定第一小区的时频资源信息。
其中, 所述第一小区的时频资源信息包括所述第二小区干扰所 述第一小区的时频资源的干扰程度信息。
需要说明的是, S704 与 S705 之间没有时间顺序的限制, 即可 以先执行 S704, 再执行 S705, 也可以先执行 S705, 再执行 S704, 还可以同时执行 S704和 S705, 本发明不做限制。
S706、 第一小区向所述第二小区发送所述第二小区的时频资源 信息, 以使所述第二小区根据所述第二小区的时频资源信息进行时 频资源分配。
S707、 第一小区根据所述第一小区的时频资源信息进行时频资 源分配。
与上述示例相对应,第一小区将载波 f3的时频资源信息发送给 第二小区, 以使第二小区根据该时频资源信息进行时频资源分配; 第一小区确定可使用资源 PRB7 的资源信息或不可使用资源 PRB4 的 资源信息, 第一小区根据该资源信息调度可使用资源 PRB7, 或避免 调度不可使用资源 PRB4, 或 MCS降阶调度不可使用资源 PRB4。
进一步地, 所述第一小区还可以根据所述第一小区的时频资源 信息, 使用所述第一小区的第一载波对所述第一小区的第二载波进 行配置, 其中, 所述第二载波为所述第一小区与所述第二小区共享 的时频资源。
具体地, 在时域上, 第一小区的 PDCCH —般占用每个时隙 1ms 的前三个 OFDM符号。 在频域上, PDCCH—般占用所有带宽。 例如, 第一小区占用 10MHz, 则 50个 PRB上都有 PDCCH。 因此即使通过调 度错开了 PDSCH在 PRB4上受到的强干扰,也无法错开 PDCCH在 PRB4 上受到的强干扰。 所以为了避免 PDCCH 受到第二小区的强干扰, 可 以釆用的方法是釆用跨载波调度。 即假设第一小区工作在多载波模 式, 同时占用载波 1 及载波 2 , 其中, 可以利用载波 1 的 PDCCH 来 分配载波 2的 PDSCH, 也就是说, 载波 2可以没有 PDCCH。 也就是上 述所描述的第一小区使用所述第一小区的第一载波对所述第一小区 的第二载波进行配置。
需要说明的是, S706 与 S707 之间没有时间顺序的限制, 即可 以先执行 S706, 再执行 S707, 也可以先执行 S707, 再执行 S706, 还可以同时执行 S706和 S707, 本发明不做限制。
