- an embodiment of the present invention provides a method for measuring power consumption of a base station, which may include the following steps.
- Step 11 The management module of the base station configures an analog load to the base station. For example, the number of actual users accessing the base station is obtained.
- the management unit of the base station configures the simulated load to the base station, where the simulated load refers to A certain number of analog users configured at the MAC (Mdium Access Control) layer of the base station.
- the difference between the simulated user and the actual user is that the actual user actively accesses the base station, and the analog user is actively configured by the management module of the base station at the MAC layer of the base station.
- the sum of the number of simulated users and the number of actual users is less than or equal to the total number of users allowed to access the base station.
- the base station saves the number of the actual user and the simulated user in the scheduling module of the base station.
- the upper limit of the number of RBs that the simulated user is allowed to occupy may be calculated according to the number of RBs occupied by the actual user of the base station. For example, the difference between the number of RBs occupied by the actual user of the base station and the number of RBs allowed by the base station and the number of RBs occupied by the actual user is the upper limit of the number of RBs that the analog user is allowed to occupy, that is, The number of RBs that the simulated user is allowed to occupy is less than or equal to the difference between the number of RBs that the base station can carry and the number of RBs occupied by the actual user.

- all or part of the RBs of the RBs that the analog user is allowed to occupy are allocated to the respective simulated users in a sequential or discrete manner according to the sequence number corresponding to the RB. For example, assign RBs with sequence numbers 1 through 9 to the first analog user, and assign RBs with sequence numbers 10 through 16 to the second analog user.
- the serial numbers are 1, 3, 4, 6,
- the RB of 9 is assigned to the first analog user, and the RBs of sequence numbers 2, 4, 5, 7, 8, and 10 are assigned to the second analog user.

- the scheduling unit of the base station notifies each analog user to transmit data using the allocated RB, and the actual user transmits data using the occupied RB. For example, after the normal downlink scheduling ends, the scheduling module of the base station may perform PDSCH (Physical Downlink Shared Channel) load scheduling, indicating that all analog users and actual users generate random data and send the baseband to the base station. . For example, after the normal downlink scheduling and the uplink scheduling are completed, the scheduling module of the base station may perform a PDCCH (physical downlink control channel) load scheduling, indicating that all analog users and actual users generate PDCCH data and send the data to the base station.

For example, if the measured output power of the RRU of the base station is 80 w, the measured output power of the RRU of the above base station under the condition of 95% load ratio and 100% power load ratio is: 80%.
- various load ratios of the base station may be simulated according to a proportional relationship between the sum of the number of simulated users and actual users and the total number of users allowed to access the base station. For example, when the sum of the number of the simulated user and the actual user is equal to the total number of users allowed to access the base station, the load ratio of the base station is 100%; when the sum of the number of the simulated user and the actual user is allowed to access the base station, When 50% of the total number of users, the load ratio of the base station is 50%.

本申请要求于 2010年 12月 28 日提交中国专利局、 申请号为 201010622545.8、 发 明名称为"一种测量方法和设备"的中国专利申请的优先权, 其全部内容通过引用结合在 本申请中。 技术领域
本发明涉及通信技术领域, 尤其涉及一种测量基站的功耗的方法和设备。 发明背景
在 LTE (Long Term Evolution, 长期演进系统) 中, 基站的大部分电能都被发射信 号的功放所消耗, 如何能够方便地测试基站不同水平的功耗等级成为电信网络运营商迫 切的需求。
现有技术中, 对基站进行最大发射功率的测量的方法主要包括: 通过构造一种全带 宽数据, 将基站允许承载的所有 RB (Resource Block, 资源块) 都应用起来, 全功率发 送上述全带宽数据, 从而实现基站的 RRU Remote RF Unit, 射频远端单元)进行满功率 发射。 然后, 测量出所述基站的 RRU的输出功率, 该输出功率即为上述基站的最大发射 功率。
在实现本发明过程中,发明人发现现有技术中的测量基站的功耗的方法至少存在如 下问题: 该方法只能测量基站的最大发射功率, 对于基站的功耗测试功能较为单一。 发明内容 本发明的实施例提供了一种测量方法和设备, 以实现灵活获取基站的输出功率的测 量结果。
本发明的一方面提供一种测量方法, 包括:
配置模拟用户, 并为所述模拟用户分配资源块;
当所述模拟用户利用所分配的资源块所占有的传输功率发送数据时,测量基站的输 出功率;
根据测量到的基站的输出功率和所述基站的输出功率理论值确定所述基站的输出 功率的测量结果。
本发明的另一方面提供一种设备, 包括:
配置单元, 用于配置模拟用户, 给所述模拟用户分配资源块和传输功率;
测量单元, 用于当所述模拟用户利用所分配的资源块所占有的传输功率发送数据 时, 测量基站的输出功率; 并根据测量到的基站的输出功率和所述基站的输出功率理论 值确定所述基站的输出功率的测量结果。
本发明实施例通过给基站配置模拟负载, 通过模拟用户利用所占用的 RB和传输功 率来发送数据, 从而可以在任一基站的负载比例情况下, 方便地获取基站的输出功率的 测量结果。 附图简要说明
图 1为本发明的一个实施例提供的一种测量基站的功耗的方法的处理流程图; 图 2为本发明的另一个实施例提供的一种测量基站的功耗的设备的结构图。 实施本发明的方式
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 术人员在没有作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。 如图 1所示, 本发明的一个实施例提供一种测量基站的功耗的方法, 可以包括如下 步骤。 步骤 11、 基站的管理模块给基站配置模拟负载。 例如, 获取接入基站的实际用户的数量, 在上述实际用户的数量较少、 小于允许接 入所述基站的用户总数的情况下, 基站的管理单元给基站配置模拟负载, 该模拟负载是 指在基站的 MAC (Mdium Access Control, 媒质接入控制) 层配置的一定数量的模拟用 户。 该模拟用户和实际用户的区别在于实际用户是主动接入所述基站的, 而模拟用户是 由基站的管理模块在基站的 MAC层主动配置的。 所述模拟用户的数量和所述实际用户的数量之和小于或者等于允许接入所述基站 的用户总数。可选的,基站将上述实际用户和模拟用户的数量保存在基站的调度模块中。 步骤 12、 确定模拟用户被允许占用的 RB的数量。
一个基站可能支持多种系统带宽, 在不同的系统带宽下分别承载不同的 RB的数量, 每个 RB对应一个序号。 基站下的小区的系统带宽越大, 则基站可承载的 RB数量越多, 基站可承载的 RB可以被分配给接入基站的各个用户, 例如实际用户和模拟用户。 例如, 基站下的小区的系统带宽为 20M, 则基站可承载 100个 RB; 基站下的小区的系统带宽为 15M, 则基站可承载 75个 RB。
本步骤中, 可以根据基站的实际用户所占用的 RB数量计算出模拟用户被允许占用 的 RB的数量上限。 例如, 获取基站的实际用户所占用的 RB数量, 基站允许承载的 RB数 量和上述实际用户所占用的 RB数量之间的差值即为上述模拟用户被允许占用的 RB的数 量上限, 也就是说, 基站确定的模拟用户被允许占用的 RB的数量小于或者等于基站可 承载的 RB数量和上述实际用户所占用的 RB数量之间的差值即可。
步骤 13、 将上述模拟用户被允许占用的 RB中的全部或部分 RB按照指定方式分配给 各个模拟用户。
在确定了模拟用户被允许占用的 RB的数量之后, 需要将上述模拟用户被允许占用 的 RB分配给各个模拟用户。
例如, 将上述模拟用户被允许占用的 RB中的全部或者部分 RB进行划分, 从而划分 出多个 RB组, 每个 RB组可以包括一个或多个 RB, 或者, 每个 RB组包含的 RB数量相同, 例如每个 RB组包含 4个 RB。 然后, 给每个模拟用户分配一个或者多个 RB组。
又如,按照 RB对应的序号,将上述模拟用户被允许占用的 RB中的全部或者部分 RB, 以顺序或者离散的方式分配给各个模拟用户。 比如, 将序号为 1至 9的 RB分配给第一个 模拟用户, 将序号为 10至 16的 RB分配给第二个模拟用户。 又如, 将序号为 1、 3、 4、 6、
9的 RB分配给第一个模拟用户, 将序号为 2、 4、 5、 7、 8和 10的 RB分配给第二个模拟用 户。
步骤 14、 确定分配给每个 RB的传输功率。
例如,将基站的允许使用的传输功率平均分配到各个实际用户和模拟用户所占用的 RB上, 则可以确定每个 RB的传输功率为基站的允许使用的传输功率除以所有用户所占 用的 RB数量所得的值, 这里的所有用户所占用的 RB数量为上述实际用户所占用的 RB数 量和分配给所有模拟用户的 RB数量之和, 这里的基站的允许使用的传输功率为功率负 载比例和基站传输功率最大值的乘积。这里的功率负载比例表示基站允许使用的传输功 率比例, 可以由基站设定。
假设功率负载比例为 100%, 基站的允许使用的传输功率为 40w, 上述实际用户和模 拟用户所占用的 RB的数量为 80, 则分配给每个 RB的传输功率为: 40 x l 00% = o,5 w。
oU
步骤 15、 当模拟用户和实际用户分别利用分配到的 RB和占用的 RB发送数据时, 通 过将测量出的基站的 RRU (Remote RF Unit, 射频远端单元) 的输出功率和 RRU的输出 功率的理论值进行比较, 根据比较结果获取 RRU的输出功率的测量结果。
根据上述模拟用户和实际用户的数量之和与允许接入所述基站的用户总数之间的 比例关系, 计算出所述基站的负载比例。 例如, 上述模拟用户和实际用户的数量之和为 95, 允许接入所述基站的用户总数为 100, 则基站的负载比例为 95%。
根据设定的功率负载比例计算出所述基站的 RRU的输出功率的理论值。 比如, 预先 设置的基站的传输功率为 100w, 功率负载比例为 100%, 上述实际用户和模拟用户所占 用的 RB的数量为 100, 则每个 RB所分配的传输功率为 lw。 当所有的模拟用户和实际用 户都利用所占用的 RB和传输功率来发送数据时, 此时可以通过功率计算出 RRU的输出 功率, 该输出功率的理论值应该为 1 OOx 1 w= 100w。
基站的调度单元通知各个模拟用户利用分配到的 RB来发送数据, 实际用户利用占 用的 RB来发送数据。 例如, 在正常的下行调度结束之后, 基站的调度模块可以执行 PDSCH (Physical Downlink Shared Channel, 下行链路共享物理信道) 负载调度, 指示 所有的模拟用户和实际用户产生随机数据并发送给基站的基带。 又如, 在正常的下行调 度和上行调度结束之后, 基站的调度模块可以执行 PDCCH (physical downlink control channel, 物理下行控制信道) 负载调度, 指示所有模拟用户和实际用户产生 PDCCH数 据并发送给基站的基带。
然后, 测量出所述基站的 RRU的输出功率。将所述基站的 RRU的输出功率的测量值 和上述基站的 RRU的输出功率的理论值进行比较,根据比较结果获取所述基站的负载比 例和所述设定的功率负载比例情况下的基站的 RRU的输出功率的测量结果。
例如, 计算出基站的 RRU的输出功率的测量值和理论值之间的比值, 将该比值确定 为所述基站的负载比例和所述设定的功率负载比例情况下的基站的 RRU的输出功率的 测量结果。 比如, 基站的 RRU的输出功率的测量值为 80 w, 则上述基站在 95%的负载比 例和 100%的功率负载比例情况下的 RRU的输出功率的测量结果为: =80%。
lOOw
在本发明实施例中, 可以根据上述模拟用户和实际用户的数量之和与允许接入基站 的用户总数之间的比例关系, 模拟出基站的各种负载比例情况。
比如, 当上述模拟用户和实际用户的数量之和与允许接入基站的用户总数相等时, 则基站的负载比例为 100% ; 当上述模拟用户和实际用户的数量之和为允许接入基站的 用户总数的 50%时, 则基站的负载比例为 50%。 然后, 根据上述基站的 RRU的输出功率 的测量结果的获取过程,获取出基站在各种负载比例情况下的 RRU的输出功率的测量结 果。
在本发明实施例中, 还可以通过同时改变上述基站的功率负载比例和负载比例, 获 取出基站在各种负载比例情况和功率负载比例情况下的 RRU的输出功率的测量结果。
该实施例通过配置不同的模拟用户总数, 使基站处于不同的负载比例的情况, 再测 量基站的射频单元的不同输出功率,得以确定上述不同输出功率和射频单元的输出功率 的理论值之间的比值, 即不同负载比例和设定的功率负载比例情况下的基站射频单元的 功耗测量结果。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程, 是可以通 过计算机程序来指令相关的硬件来完成,所述的程序可存储于一计算机可读取存储介质 中, 该程序在执行时, 可包括如上述各方法的实施例的流程。 其中, 所述的存储介质可 为磁碟、光盘、只读存储记忆体(Read-Only Memory, ROM)或随机存储记忆体(Random Access Memory, RAM) 等。 本发明的另一个实施例还提供了一种设备, 可以用于实现上述实施例提供的功耗测 量方法中基站执行的动作。 例如, 如图 2所示, 该设备包括:

比如, 上述模拟用户和实际用户的数量之和为 95, 允许接入所述基站的用户总数为 100, 则基站的负载比例为 95%。 预先设置的基站的传输功率为 100w, 功率负载比例为 100%, 上述实际用户和模拟用户所占用的 RB的数量为 100, 则每个 RB所分配的传输功 率为 lw。 当所有的模拟用户和实际用户都利用所占用的 RB和传输功率来发送数据时, 此时可以通过功率计算出 RRU的输出功率, 该输出功率的理论值应该为 100xlw=100w。
基站的 RRU的输出功率的测量值为 80 w,则上述基站在 95%的负载比例和 100%的功 率负载比例情况下的 RRU的输出功率的测量结果为: =80%。
