- the wireless communication network has a large number of devices operating on the Internet, and the network scale continues to grow at a relatively fast rate, and the proportion of large configuration stations is increasing.
- multi-carrier technology is widely used in GSM (Global System of Mobile communication) and WCDMA (Wideband Code Division Multiple Address).
- the existing radio remote unit is an important form of base station equipment in a wireless communication system, and generally includes a power amplifier unit and a radio frequency small signal processing unit, wherein the power amplifier unit is generally designed as a multi-carrier power amplifier.
- a multi-carrier power amplifier refers to a power amplifier capable of carrying multiple carrier frequency bands in the same wireless system or multiple wireless systems.
- the main features of this type of multi-carrier power amplifier include: It can support multiple carriers for air interface transmission at the same time, and can realize power sharing between multiple carriers.
- multi-carrier power amplifiers are generally designed as broadband power amplifiers, that is, power amplification can be achieved in a large frequency band.
- the power amplifier tube is the main device for transmitting power to the antenna in the carrier frequency.
- Its power consumption is composed of static and dynamic components. Due to the nonlinear characteristics of the power amplifier, even if it does not transmit power, it is necessary to apply a fixed bias voltage. The purpose is to make the power amplifier work in a linear region and ready to transmit power. This part of the power consumption is called static power consumption.
- the power consumption of the power amplifier also includes another part of the power consumption, that is, dynamic power consumption.
- the dynamic power consumption depends on whether the time slot is occupied. If there is traffic on the time slot, the power amplifier must transmit power, and the part with relatively static power consumption increases. The dynamic power consumption is divided, and the higher the carrier frequency output power, the higher the dynamic power consumption; if there is no traffic, the dynamic power consumption of the power amplifier is 0, only static power consumption.
- the power consumption of the power amplifier tube in the seven time slots of 18 1 to 18 7 in which the power amplifier tube is in the working time slot, the energy consumption is dynamic energy plus static energy consumption.
- the power amplifier tube still has static energy consumption, that is, when the dynamic power consumption is 0, only the power amplifier is turned off, and after the static power consumption is eliminated, the power consumption of the entire power amplifier is Is 0.
- the power amplifier can be divided into a single carrier power amplifier and a multi-carrier power amplifier according to the configured number of carriers.
- a single-carrier power amplifier has only one carrier on its power amplifier.
- a multi-carrier power amplifier refers to two or more carriers configured on one power amplifier.
- the power amplifier can be divided into a main carrier frequency board and a non-primary carrier frequency board; the resource block part of the main carrier frequency board is used to transmit control signaling of the system, and the remaining The resource block is used to send traffic; the resource block on the non-primary carrier frequency board is only used to send traffic.
- the existing power control mechanism of the power amplifier is in the absence of a traffic time period (such as a time slot), that is, when the processing resource module or channel resource of the power amplifier is in an idle state and the dynamic power consumption is 0, the time zone is further advanced.
- a traffic time period such as a time slot
- the existing power amplifier power control technology for such time slot shutdown is only applicable to a single carrier.
- the power amplifier can be performed. The gap is turned off. Since the multi-carrier power amplifier has multiple carrier frequencies, the probability that all carriers of the multi-carrier power amplifier will be idle in a certain time slot will be very small compared to the single-carrier device, which greatly affects the multi-carrier device.

- the multi-carrier frequency power amplifier includes a main carrier frequency board and a non-main carrier frequency board, the main carrier frequency board is a working carrier frequency board where the main carrier frequency is located, and the main carrier frequency has some or all time slots used for transmission system control.
- time slot of the primary carrier frequency transmission control signaling is the primary carrier frequency board

- the primary carrier frequency of the primary carrier frequency board is used to send control signaling, so In this time slot, even if all non-primary carrier frequencies are in an idle state (no service data is allocated), the primary carrier frequency cannot be turned off.

- the time slot of the data is also the time slot in which the primary carrier board can be turned off.
- first assigning service data to the non-carrier frequency corresponding to the time slot of the main carrier board that cannot turn off the carrier frequency can improve the effective utilization rate of the main carrier board and save the static power consumption of the main carrier board. . Because, in the time slot where the main carrier board cannot turn off the carrier frequency, regardless of these time slots If the non-primary carrier frequency is idle, the carrier frequency board cannot be turned off.

- the energy-saving control method for the multi-carrier frequency power amplifier resource in the second embodiment of the present invention includes the following steps:
- Step 201 Allocate service data to the primary carrier board, where if the working carrier frequency of the primary carrier board is allocated, the service data is allocated to the working carrier frequency of the non-primary carrier board, and the non-primary load
- the working carrier frequency allocation service data of the frequency board includes: allocating service data to all carrier frequencies in one time slot of the non-primary carrier frequency board, and then allocating service data points to the working carrier frequency in another time slot;
- Step 202 After the service data is allocated, the non-primary carrier board is turned off in an idle time slot, where the idle time slot means that all carrier frequencies of the carrier board are not in the time slot. Business data distribution.
- the specific step of allocating service data to the main carrier board is based on whether the main carrier board can be turned off or not, and the time slot with the carrier frequency can be turned off.
- the main carrier board cannot turn off the time slot of the carrier frequency. At this time, the main carrier board is not energy-saving controlled, and the service data can be allocated to the main carrier board according to specific needs.

Scheduling.
- the second case of allocating service data to the main carrier board is that the main carrier board has a time slot capable of turning off the carrier frequency, and the time slot of the off carrier frequency means In the time slot, if the primary carrier frequency board or the non-primary carrier frequency board can perform the shutdown operation when all carrier frequencies are idle; conversely, if the time slot of the primary carrier frequency is used to send control signaling, then No off-operation can be performed in the time slot regardless of whether other carrier frequencies of the main carrier board are idle.
- the time slot is a time slot of the carrier frequency board (main carrier board) that cannot be turned off. Since each carrier frequency of the non-primary carrier frequency board is used to transmit service data, the non-primary carrier frequency board does not have a time slot in which the carrier frequency cannot be turned off.

- the time slot for transmitting the control signaling by the main carrier frequency board is a time slot in which the main carrier frequency board cannot be turned off, and the other time slots used by the main carrier frequency board for transmitting service data is to turn off the main The time slot of the carrier board.
- the partial time slots of the primary carrier frequency such as the first four time slots, are used to send control signaling, and the time slots of the four transmission control signaling are the unstoppable carrier frequencies of the primary carrier frequency board.
- Time slot therefore, preferentially assigning service data to other carrier frequencies corresponding to the time slots of the non-offable carrier frequency, Thereby increasing the probability that the working carrier channel is idle corresponding to other time slots that can turn off the carrier frequency.

- the second ⁇ corresponds to the identifier 2 in the circle in the figure, and the remaining service data is allocated in the order of the time slot to the main carrier frequency and other carrier frequencies of the main carrier board corresponding to the time slot in which the carrier frequency can be turned off;
- the foregoing step 202 allocates the remaining service data to the non-primary carrier frequency in the slot order.
- the main carrier board After the service data is allocated, the following situations are also included: In the first case, if there is a free time slot in the time slot of the main carrier board that is not allocated service data, the main carrier board is turned off in the idle time slot, that is, the main carrier board service data processing If the capacity is greater than the service data to be processed, the case where the time slot of the main carrier board that can be turned off of the main carrier frequency board has a free time slot; in the second case, if the main carrier board is not available Turn off the non-primary corresponding to the time slot of the main carrier board After all the service data is allocated by the carrier frequency, the main carrier board is turned off in other time slots in which the main carrier board can be turned off, that is, if the main carrier board is used to transmit control signaling.
- the primary carrier board is turned off in all time slots of the main carrier board that can be turned off; If the processing capacity of the primary carrier board is greater than the service data, all the service data is allocated to the primary carrier board and the non-primary carrier board is turned off.
- step 201 if the working carrier frequency of the main carrier board is allocated, the service data is allocated to the working carrier frequency of the non-main carrier board, and the working carrier frequency of the non-main carrier board is allocated.
- Allocating service data includes performing service data distribution to all carrier frequencies in one time slot of the non-primary carrier frequency board, and then allocating service data to the working carrier frequency in another time slot, where.
- the above control method for the multi-carrier frequency power amplifier resource schedules the channel resources of the multi-carrier frequency power amplifier from the perspective of the time slot, and increases the probability that the carrier with multiple carrier frequency powers will appear idle state in some time slots capable of turning off the carrier frequency.

Description
多载频功放资源的控制方法以及装置 技术领域 本发明涉及通信技术领域， 尤其涉及一种多载频功放资源的控制方法 以及装置。 背景技术
无线通信网经过二十多年的发展， 目前已有数量庞大的设备在网上运 行， 并且网络规模仍以较快速度持续增长， 大配置站型所占比例越来越大。 随着技术的发展， 多载波技术在 GSM(Global System of Mobile communication, 全球移云力通信系统)禾口 WCDMA(Wideband Code Division Multiple Address, 宽带码分多址)中得到普遍应用。
现有的射频拉远单元 （RRU) 是无线通信系统中基站设备的一种重要 形态， 一般包括功放单元和射频小信号处理单元， 其中功放单元一般设计 为多载波功放的方式。 具体来说， 多载波功放是指同一个无线系统或者多 种无线系统中， 能够承载多个载波频段的功率放大器。 此类多载波功放的 主要特点包括： 可以支撑多个载波同时进行空口传输， 能够实现多个载波 之间的功率共享； 由于受到了功放最大发射功率的限制， 一般来说， 载波 数量越多， 能够配置的每载波最大发射功率也会相应降低； 多载波功放一 般设计成宽带功放的方式， 即能够在很大的频段上实现功率的放大。
在多载波功放中， 功放管是载频中向天馈发射功率的主要器件， 它的 功耗有静态和动态两部分组成。 由于功放的非线性特性限制， 即使它不发 射功率， 也需要施加一个固定的偏置电压， 目的是使得功放工作在线性区 域， 随时准备发射功率， 这部分消耗的功耗就叫做静态功耗。 功放功耗还 包括另外一部分功耗， 即动态功耗， 动态功耗取决于时隙是否被占用， 如 果时隙上有话务， 功放必然要进行功率发射， 此时相对静态功耗增加的部
分就是动态功耗， 且载频输出功率越高动态功耗越高； 若无话务， 功放的 动态功耗为 0， 仅有静态功耗。
如图 1所示， 功放管在 181到187的七个时隙内的能耗情况，其中功放 管处于工作状态的时隙下， 能耗为动态能耗加上静态能耗两部分， 而当功 放管处于空闲状态的时隙内时， 功放管依然存在静态能耗， 即动态功耗为 0 的情况下，只有进一歩关断功放，消除静态功耗后，整个功放的功耗才为 0。
在通信系统中， 按配置的载波数， 功放可以分为单载波功放和多载波 功放。 单载波功放即功放上仅配有一个载波， 多载波功放指一个功放上配 置 2个或更多的载波数。 当一个通信系统中配有多个多载波功放时， 一般 可以将功放分为主载频板和非主载频板； 主载频板上的资源块部分用来发 送系统的控制信令， 剩余的资源块用来发送业务； 非主载频板上的资源块 仅用来发送业务。
现有的功放电源控制机制， 是在没有话务时间段 （如时隙） 内， 即功 放的处理资源模块或信道资源处于空闲状态而动态功耗为 0 的情况下， 进 一歩在该时间段内关断功放， 关断后的静态功耗以及整个功放的功耗均为 0。
然而， 现有的这种时隙关断的功放电源控制技术仅适用于单载波， 对 于多载波功放， 需要功放所在的所有载波在某一时隙内均处于空闲状态时， 该功放才能够进行时隙级的关断。 由于多载波功放具有多个载频， 因此在 某个特定时隙上， 多载频功放的所有载波都出现空闲的概率相对于单载波 设备来说会是非常小， 大大影响了多载波设备关断的效率， 难于达到节能 目的。 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， 所描述的实施例仅仅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， 本领域技术人员所获得的 所有其他实施例， 都属于本发明保护的范围。
本发明实施例提供一种多载频功放资源的控制方法以及装置， 从时隙 的角度对多载频功放的信道资源进行调度， 增加多载频功的载波在一些可 关断载频的时隙下出现空闲状态的几率， 让后再以时隙级的控制粒度对多 载波功放进行电源关断控制， 从而达到减少多载频功放的静态功耗浪费的 目的。
在本发明实施例中， 上述多载频功放资源的控制方法可应用于 GSM、
WCDMA、 LTE、 UMTS等 2G或 3G系统中， 对多载频功放的信道资源块 进行调度。 如图 2所示为多载频功放中的多载频信道资源， 其中主 B板代 表主载频板、 非主 B板代表非主载频板、 C代表控制信令、 T代表业务数 据、 数字 0~7代表时隙顺序。 所述多载频功放包括主载频板和非主载频板， 所述主载频板为主载频所在的工作载频板， 主载频有部分或者全部时隙用 于发送系统的控制信令， 其中主载频发送控制信令的时隙为所述主载频板
的不可关断载频的时隙， 也就是在该时隙内主载频板不能关闭。 主载频板 的主载频的其它时隙以及其它非主载频用于发送业务数据， 当这些时隙对 应的各载频均空闲时， 可在该空闲时隙内关闭主载频板， 以节约载频板的 静态功耗。 非主载频板的各个载频用于发送业务数据， 为可关断载频的时 隙的工作载频板。
实施例一
如图 3所示， 本发明实施例一多载频功放资源的控制方法， 包括以下 歩骤：
歩骤 101、 向不可关断载频的时隙内的工作载频分配业务数据； 歩骤 102、在所述向不可关断载频的时隙内的工作载频分配业务数据完 成后， 向可关断载频的时隙内的工作载频分配所述业务数据， 所述向可关 断载频的时隙内的工作载频分配所述业务数据包括向一所述时隙内的所有 工作载频分配业务数据后再向另一所述时隙内的工作载频分配业务数据； 歩骤 103、在所有载频均没有业务数据分配的可关断载频的时隙内关断 所述载频所在的工作载频板。
请一并参阅图 2， 上述歩骤 101中， 所述不可关断载频的时隙内的工作 载频是指主载频板上与主载频用于发送控制信令的时隙对应的非主载频。 所述主载频用于发送控制信令的时隙为所述主载频板不可关断的时隙， 该 时隙内， 主载频板的主载频用于发送控制信令， 因此在该时隙内， 即使所 有非主载频均处于空闲状态（没有被分配业务数据），主载频也不能被关断。 对于非主载频板来说， 非主载频板的所有载频均用于发送业务数据， 因此 所有时隙均属于可关断载频板的时隙， 而所述主载用于发送业务数据的时 隙也为所述主载频板可关断的时隙。
上述性能分析方法中先向主载频板中不可关断载频的时隙对应的非载 频分配业务数据可以提高主载频板的有效利用率并同时节省维持主载频板 的静态功耗。 因为， 在主载频板不可关断载频的时隙内， 无论这些时隙内
非主载频是否空闲， 均不能进行载频板关断的操作， 所以， 将业务数据优 先分配给这些时隙内的非主载频就会加大载频板 （包括主载频板和非主载 频板） 在可关断载频的时隙内出现所有载频空闲的几率， 从而提高时隙级 关断的节能效率。 如图 4所示， 上述歩骤 102中， 在完成向不可关断载频 的时隙内的工作载频分配业务数据之后（对应图中圆圈内的标记 1的歩骤）， 所述向可关断载频的时隙内的工作载频分配所述业务数据主要是指向主载 频板上与可关断载频的时隙对应的工作载频和非主载频板的工作载频分配 业务数据。 所述向可关断载频的时隙对应的主载频板的工作载频和非主载 频板的工作载频分配业务数据的具体顺序为在所述与可关断载频的时隙对 应的主载频板的工作载频分配 （对应图中圆圈内的标记 2 的歩骤） 完后， 再向所述与可关断载频的时隙对应非主载频板的工作载频分配业务数据 (对应图中圆圈内的标记 3的歩骤）。 如果主载频板的处理能力大于需要处 理的业务数据， 也就是业务数据不足以占据完所述主载频板的工作载频资 源时， 所述非主载频板可以在一个时间周期的所有时隙内都一直保持关断 状态， 有效节省静态能耗。
此外， 上述歩骤 102 中， 所述向可关断载频的时隙内的工作载频分配 所述业务数据包括向一所述时隙内的所有工作载频分配业务数据后再向另 一所述时隙内的工作载频分配业务数据， 也就是说从时隙的纬度将业务数 据分配给各个可关断载频的时隙对应的所有载频， 例如， 如图 4所示， 非 主载频板有三个载频、 8个时隙 （0〜7 )， 向非主载频板分配业务数据时， 先向对应第一个时隙（如 0 )的三个载频分配业务数据， 饱和后再向下一个 时隙 （如） 分配业务数据， 直到所述业务数据被分配完。
上述歩骤 103 中， 在所有载频均没有业务数据分配的可关断载频的时 隙内关断所述载频所在的工作载频板， 也就是说在关断载频的时隙中， 如 果某个时隙内载频板 （包括主载频板和非主载频板） 的所有载频均没有被 分配业务数据而处于空闲状态， 则在该时隙内关断所述载频板， 以消除维
持载频板处于工作状态的静态功耗。
上述本发明实施例提供的多载频功放资源的控制方法， 从时隙的角度 对多载频功放的信道资源进行调度， 增加多载频功的载波在一些可关断载 频的时隙下出现空闲状态的几率， 然后再以时隙级的控制粒度对多载波功 放进行电源关断控制， 从而达到减少多载频功放的静态功耗浪费的目的。
实施例二
如图 5所示， 本发明实施例二多载频功放资源的节能控制方法， 包括 以下歩骤：
歩骤 201、 向主载频板分配业务数据， 其中如果所述主载频板的工作载 频分配完后， 则向非主载频板的工作载频分配业务数据， 所述向非主载频 板的工作载频分配业务数据包括完成向所述非主载频板一时隙内所有载频 分配业务数据后再向另一时隙内的工作载频分配业务数据分；
歩骤 202、所述业务数据分配完之后， 在空闲时隙内关断所述非主载频 板， 所述空闲时隙是指在所述时隙内， 载频板的所有载频均没有业务数据 分配。
上述歩骤 201 中， 向主载频板分配业务数据的具体歩骤基于主载频板 是否可关断而具有可关断载频的时隙两种情况。
第一种情况是上述主载频板不可关断载频的时隙， 此时不对主载频板 进行节能控制， 业务数据可以根据具体需要分配至主载频板上。
如图 6和 7所示， 上述歩骤 201中向主载频板分配业务数据分配至的 歩骤包括：
歩骤 301a、 分配至向主载频板的主载频分配业务数据调；
歩骤 302a、 所述主载频板的主载频分配完后， 向所述主载频板的其它 非主载频分配业务数据分配至。
在实际应用的一些场景下， 所述主载频板不能关断， 例如， 为了保证 覆盖， 主载频板中的主载频需要一直保持满功率发射， 或主载频板中主载
频的所有时隙均用于发送控制信令。 由于主载频板不可关断， 因此， 主要 考虑如何根据无线信道的变化， 如根据用户离基站的远近、 用户即时信道 状态、 承载业务的服务质量需求 （QoS ) 等因素， 进行载频信道资源调度。
上述歩骤 201 中， 向主载频板分配业务数据的第二种情况是所述主载 频板具有可关断载频的时隙， 所述可关断载频的时隙是指在某时隙内， 如 果主载频板或非主载频板在所有载频均空闲的情况下可以进行关断操作； 反之， 如果主载频的该时隙用于发送控制信令， 则在该时隙内无论主载频 板的其它载频是否空闲， 都不能进行关断操作， 该时隙为载频板 （主载频 板） 的不可关断载频的时隙。 由于非主载频板的各个载频均用于发送业务 数据， 因此非主载频板不存在不可关断载频的时隙。
如图 8所示， 上述主载频板可关断载频的时隙时， 上述歩骤 201 中将 业务数据分配至主载频板的歩骤包括：
歩骤 301b、 向与所述主载频板用于发送控制信令的时隙对应的非主载 频分配业务数据分配至可关断载频的时隙；
歩骤 302b、 如果分配完所述主载频板用于发送控制信令的时隙对应的 非主载频后， 则向与所述主载频板用于发送业务数据的其它时隙对应的工 作载频分配业务数据， 所述向与所述主载频板其它时隙对应的工作载频分 配业务数据包括完成向所述主载频板一所述其它时隙内所有载频分配业务 数据后再向另一所述其它时隙内的工作载频分配业务可关断载频的时隙分 配至可关断载频的时隙。
上述主载频板用于发送控制信令的时隙为不可关断所述主载频板的时 隙， 所述主载频板用于发送业务数据的其它时隙为可关断所述主载频板的 时隙。
如图 4所示， 上述主载频的部分时隙， 如前 4个时隙用于发送控制信 令， 则该 4个发送控制信令的时隙为主载频板的不可关断载频的时隙， 因 此， 优先将业务数据分配至与所述不可关断载频的时隙对应的其它载频上，
从而增加与其它可关断载频的时隙对应的工作载频信道空闲的几率。 所述 主载频板具体调度顺序是， 第一歩与图 7中的圆圈内的标识 1对应， 先将 业务数据分配至不可关断载频的时隙对应的主载频板上的工作载频； 第二 歩与图中圆圈内的标识 2对应， 将剩余业务数据按时隙的顺序分配至与可 关断载频的时隙对应的主载频板的主载频和其它载频； 然后对应图中圆圈 内标识 3的是上述歩骤 202将剩余的业务数据按时隙顺序分配至非主载频 上述所述业务数据分配完之后还包括以下几种情形： 第一种情形， 如 果所述可关断主载频板的时隙中存在没有分配业务数据的空闲时隙， 则在 所述空闲时隙内关断所述主载频板， 也就是说所述主载频板业务数据处理 能力大于所需要处理的业务数据， 则出现所述主载频板的可关断主载频板 的时隙存在空闲时隙的情况； 第二种情形， 如果向所述主载频板与不可关 断主载频板的时隙对应的非主载频分配完所有业务数据， 则在可关断主载 频板的其它时隙内关断所述主载频板， 也就是说如果与所述主载频板用于 发送控制信令的时隙对应的非主载频的业务数据处理能力大于需要处理的 所述业务数据， 则在所有可关断主载频板的时隙内关断所述主载频板； 第 三种情形， 如果所述主载频板的处理能力大于所述业务数据， 则将所述业 务数据全部分配给所述主载频板并关断所述非主载频板。
上述歩骤 201 中， 如果所述主载频板的工作载频分配完后， 则向非主 载频板的工作载频分配业务数据， 所述向所述非主载频板的工作载频分配 业务数据包括完成向所述非主载频板一时隙内所有载频分配业务数据后再 向另一时隙内的工作载频分配业务数据， 其中。
上述多载频功放资源的控制方法， 从时隙的角度对多载频功放的信道 资源进行调度， 增加多载频功的载波在一些可关断载频的时隙下出现空闲 状态的几率， 然后再以时隙级的控制粒度对多载波功放进行电源关断控制， 从而达到减少多载频功放的静态功耗浪费的目的。
实施例三
如图 9和 10所示， 本发明实施例三提供与上述实施例一对应的一种多 载频功放资源的控制装置， 包括数据分配单元以及节能控制单元， 其中： 所述数据分配单元用于向不可关断载频的时隙内的工作载频分配业务 数据， 并在所述向不可关断载频的时隙内的工作载频分配业务数据完成后， 向可关断载频的时隙内的工作载频分配所述业务数据， 所述向可关断载频 的时隙内的工作载频分配所述业务数据包括向一所述时隙内的所有工作载 频分配业务数据后再向另一所述时隙内的工作载频分配业务数据。

所述数据分配单元向可关断载频的时隙内的工作载频分配所述业务数 据包括向主载频板上与可关断载频的时隙对应的工作载频和非主载频板的 工作载频分配业务数据。
所述向可关断载频的时隙对应的主载频板的工作载频和非主载频板的 工作载频分配业务数据包括在所述与可关断载频的时隙对应的主载频板的 工作载频分配完后， 再向所述与可关断载频的时隙对应非主载频板的工作 载频分配业务数据。
所述主载频用于发送控制信令的时隙为所述主载频板不可关断的时 隙， 所述主载用于发送业务数据的时隙为所述主载频板可关断的时隙。
所述节能控制单元用于在所述业务数据分配完后， 在所有载频均没有 业务数据分配的可关断载频的时隙内关断所述载频所在的工作载频板。
可见， 上述多载频功放资源的节能控制装置从时隙的纬度将需要处理 的业务数据分配至各个与可关断载频的时隙对应的工作载频上， 使得可关 断载频的时隙内的所有载频出现没有业务数据分配的几率显著增加， 可以 说如果按所述节能控制装置提供的业务数据的分配方法进行业务数据分 配， 只要多载频功放的处理或者负荷能力大于所需处理的业务数据， 则必
然出现没有可关断载频的时隙内没有业务数据分配给载频的情况， 从而有 效提高载频板时隙关断的节能效率。
实施例四
如图 11所示， 本发明实施例四提供与上述实施例二对应的一种多载频 功放资源的节能控制装置， 包括数据分配单元以及节能控制单元， 其中： 所述数据分配单元用于向主载频板分配业务数据， 其中如果所述主载 频板的工作载频分配完后， 则向非主载频板的工作载频分配业务数据， 所 述向所述非主载频板的工作载频分配业务数据包括完成向所述非主载频板 一时隙内所有载频分配业务数据后再向另一时隙内的工作载频分配业务数 据；
所述节能控制单元用于在所述业务数据分配完之后， 在空闲时隙内关 断所述非主载频板， 所述空闲时隙是指在所述时隙内， 载频板的所有载频 均没有业务数据分配。
所述数据分配单元向主载频板分配业务数据包括先向与所述主载频板 用于发送控制信令的时隙对应的非主载频分配业务数据； 如果分配完所述 主载频板用于发送控制信令的时隙对应的非主载频后， 则向与所述主载频 板用于发送业务数据的其它时隙对应的工作载频分配业务数据， 所述向与 所述主载频板其它时隙对应的工作载频分配业务数据包括完成向所述主载 频板一所述其它时隙内所有载频分配业务数据后再向另一所述其它时隙内 的工作载频分配业务。
所述主载频板用于发送控制信令的时隙为不可关断所述主载频板的时 隙， 所述主载频板用于发送业务数据的其它时隙为可关断所述主载频板的 时隙。
所述数据分配单元分配完业务数据之后还包括如果所述可关断主载频 板的时隙中存在没有分配业务数据的空闲时隙， 则在所述空闲时隙内关断 所述主载频板。
如果所述数据分配单元向所述主载频板与不可关断主载频板的时隙对 应的非主载频分配完所有业务数据， 则在可关断主载频板的其它时隙内关 断所述主载频板。
如果所述主载频板的处理能力大于所述业务数据， 则将所述业务数据 全部分配给所述主载频板并关断所述非主载频板。
可见， 上述多载频功放资源的节能控制装置的所述第一数据分配单元 先将业务数据分配至与主载频板不可关断载频的时隙对应的其它载频， 在 分配完与主载频板不可关断载频的时隙对应的其它载频后， 将剩余业务数 据按时隙的顺序分配至与可关断载频的时隙对应的主载频板的主载频和其 它载频。 所述节能控制模块先遍历主载频的各个可关断载频的时隙， 在可 关断载频的时隙的空闲时隙内关断主载频板； 再遍历所述非主频板的各个 时隙， 在空闲时隙内关断所述非主载频板， 从而通过功放资源的合理分配 来提高时隙关断的节能效率。
