其中, 可以根据各当前分组信道上的编码方式确定是否存在分组业务 高阶调制信道, 当某分组信道存在高阶编码方式时, 可以认为该信道为分 组业务高阶调制信道,一般情况下,可以认为调制编码方式( Modulat ion and Coding Scheme, MCS ) 5 ~ 9 , 或者 QPSK ( Quaternary Phase Shif t Keying , 四相相移键控)、 16QAM ( Quadrature Ampl i tude Modulat ion, 正交幅度调 制)、 32QAM等调制方式下对应的编码方式为高阶编码方式。 需要说明的是, 对于何种编码方式为高阶编码方式的确定也可以采用其他的原则, 本实施 例不做限定。 而预定额度与所述各分组业务高阶调制信道的编码方式对应, 分配给分组业务高阶调制信道的功率小于或等于其预定额度。此处, MCS5 ~ 9一般为 8PSK ( 8 Phase Shif t Keying , 8进制相移键控)调制方式下的编 码方式。  Wherein, whether there is a packet service high-order modulation channel according to an encoding manner on each current packet channel, when a certain packet channel has a high-order coding mode, the channel may be regarded as a packet service high-order modulation channel, and generally, Modulation and Coding Scheme (MCS) 5 ~ 9, or QPSK (Quaternary Phase Shift Keying), 16QAM (Quadature Amplitude Modulation), 32QAM The corresponding coding mode in the modulation mode is a high-order coding mode. It should be noted that other principles may be adopted for determining which coding mode is a high-order coding mode, which is not limited in this embodiment. The predetermined amount corresponds to the coding mode of the high-order modulation channel of each packet service, and the power allocated to the packet service high-order modulation channel is less than or equal to its predetermined amount. Here, MCS5 ~ 9 is generally 8PSK (8 Phase Shift Keying) modulation mode.
本发明实施例中, 可以把剩余功率的全部或部分分配给当前时隙的分 组业务高阶调制信道理解为功率的动态共享。 而该步骤中, 可以采用多种 方式将该功放在当前时隙的剩余功率分配给各分组业务高阶调制信道, 例 如采用轮询机制或者随机地将当前时隙的剩余功率分配给某些或全部分组 业务高阶调制信道等等。 可以将全部剩余功率都分配给分组业务高阶调制 信道, 也可以将部分剩余功率都分配给分组业务高阶调制信道。 也就是说, 可以将剩余功率的全部用于共享也可以只将剩余功率的部分(例如 80% )用 于共享。 本实施例以及本发明其他实施例中, 可以将用于共享的剩余功率 称为共享剩余功率。 In the embodiment of the present invention, all or part of the remaining power may be allocated to the current time slot. Group service high-order modulation channels are understood as dynamic sharing of power. In this step, the remaining power of the current slot can be allocated to each packet service high-order modulation channel in multiple manners, for example, by using a polling mechanism or randomly allocating the remaining power of the current slot to some or All packet services high-order modulation channels and so on. All of the remaining power may be allocated to the packet service higher order modulation channel, or part of the remaining power may be allocated to the packet service higher order modulation channel. That is to say, all of the remaining power can be used for sharing or only a portion of the remaining power (for example, 80%) can be used for sharing. In this embodiment and other embodiments of the present invention, the remaining power for sharing may be referred to as shared residual power.
本实施例对于剩余功率的分配方式不做限定, 只要能将剩余功率分配 给分组业务高阶调制信道即可。  In this embodiment, the manner of allocating the remaining power is not limited, as long as the remaining power can be allocated to the packet service high-order modulation channel.
通过本实施例的功率控制方法, 将功放在当前时隙的剩余功率分配给 分组业务高阶调制信道, 从而对分组业务高阶调制信道进行功率推升, 使 功放的功率得到充分地利用, 进一步地, 使得分组无线业务的链路可以获 得载干比增益, 从而使分组无线业务的性能也得到提升。  With the power control method of the embodiment, the remaining power of the power slot in the current time slot is allocated to the packet service high-order modulation channel, so that the power of the packet service high-order modulation channel is boosted, so that the power of the power amplifier is fully utilized, and further Therefore, the link of the packet radio service can obtain the carrier-to-interference ratio gain, so that the performance of the packet radio service is also improved.
如前所述, 可以采用轮询机制将功放当前时隙的剩余功率分配给当前 时隙的分组业务高阶调制信道, 本发明实施例将做详细描述, 如图 2所示, 本发明另一实施例提供一种功率控制方法, 该方法可以包括:  As described above, the polling mechanism can be used to allocate the remaining power of the current time slot of the power amplifier to the packet service high-order modulation channel of the current time slot, which will be described in detail in the embodiment of the present invention. As shown in FIG. 2, another Embodiments provide a power control method, which may include:
S201 : 根据功放的最大发射功率和当前时隙各载频对应的信道的总功 率需求确定该功放当前时隙的剩余功率;  S201: determining, according to a maximum transmit power of the power amplifier and a total power requirement of a channel corresponding to each carrier frequency of the current time slot, determining a remaining power of the current time slot of the power amplifier;
该步骤的处理过程与图 1所示实施例中 S101基本相同,此处不再赘述。 如果确定出该功放当前时隙的剩余功率大于 0, 执行 S202。  The processing of this step is basically the same as that of S101 in the embodiment shown in FIG. 1, and details are not described herein again. If it is determined that the remaining power of the current time slot of the power amplifier is greater than 0, S202 is performed.
S202: 判断是否存在分组业务高阶调制信道;  S202: Determine whether there is a packet service high-order modulation channel;
由于分组业务高阶调制信道的调制方式的因素, 在发射的过程中, 需 要相对于载频最大发射功率进行一定额度的功率回退后进行发射。 因此, 在确定功放在当前时隙存在剩余功率时, 可以将判断是否存在分组业务高 阶调制信道, 如果存在, 则可以将剩余功率分配给分组业务高阶调制信道, 即执行 S203 , 从而可以实现功放功率的动态共享。 而如果不存在分组业务 高阶调制信道, 则不对剩余功率进行分配。 Due to the modulation mode of the high-order modulation channel of the packet service, in the process of transmitting, a certain amount of power back-off is required with respect to the maximum transmission power of the carrier frequency to be transmitted. Therefore, when it is determined that there is remaining power in the current time slot, it may be determined whether there is a packet service high-order modulation channel, and if present, the remaining power may be allocated to the packet service high-order modulation channel. That is, S203 is executed, so that dynamic sharing of power amplifier power can be realized. If there is no packet service high-order modulation channel, the remaining power is not allocated.
在该步骤中, 可以采取多种常用的手段进行确定是否存在分组业务高 阶调制信道。 例如, 可以根据各当前分组信道上的编码方式确定是否存在 分组业务高阶调制信道, 当某分组信道存在高阶编码方式时, 可以认为该 信道为分组业务高阶调制信道, 具体可以参照图 1 所示实施例中的相关描 述。  In this step, a plurality of commonly used means can be taken to determine whether there is a packet service high-order modulation channel. For example, it may be determined whether there is a packet service high-order modulation channel according to an encoding manner on each current packet channel. When a packet channel has a high-order coding mode, the channel may be regarded as a packet service high-order modulation channel. A related description in the illustrated embodiment.
S203 : 根据分组业务高阶调制信道的预定额度, 将共享剩余功率分配 给某一分组业务高阶调制信道。  S203: Allocate the shared residual power to a certain packet service high-order modulation channel according to a predetermined amount of the packet service high-order modulation channel.
每个分组业务高阶调制信道的预定额度与该信道的调制方式相关, 比 如 A信道的调制方式为 8PSK , 其预定额度为 1. 8dB , 也就是说最多在原有 基础上提升 1. 8dB,信道 B的调制方式为 32QAM, 其预定额度为 4dB , 也就是 说最多在原有基础上提升 4dB。 需要说明的是, 本实施例中, 可以将剩余功 率以及预定额度以 dB为单位表示, 当然也可以用其他的单位表示, 本发明 实施例不做限定。  The first predetermined amount of the high-order modulation channel of each packet service is related to the modulation mode of the channel, for example, the modulation mode of the A channel is 8PSK, and the predetermined amount is 1.8 dB, that is, the channel is up to 1.8 dB at the original level. The modulation mode of B is 32QAM, and its predetermined amount is 4dB, which means that it can be increased by 4dB at the original level. It should be noted that, in this embodiment, the remaining power and the predetermined amount may be expressed in units of dB, and may be represented by other units, which is not limited in the embodiment of the present invention.
一般情况下, 可以根据分组业务高阶调制信道的预定额度尽量满额的 将剩余功率分配出去, 但是也可以不满额分配。 需要说明的是, 本实施例 中, 所谓满额也就是在剩余功率足够的情况下, 给分组业务高阶调制信道 分配的剩余功率等于其预定额度, 所谓不满额分配也就是说, 给分组业务 高阶调制信道分配的剩余功率小于其预定额度, 例如某分组业务高阶调制 信道的预定额度为 1. 8dB , 只分配 1. 5dB给该信道。  In general, the remaining power may be allocated as much as possible according to the predetermined amount of the high-order modulation channel of the packet service, but may also be dissatisfied. It should be noted that, in this embodiment, the full amount, that is, when the remaining power is sufficient, the remaining power allocated to the high-order modulation channel of the packet service is equal to its predetermined amount, and the so-called dissatisfaction allocation means that the packet service is high. 5dB对该频道。 The first-order modulation channel allocation of the remaining power is less than its predetermined amount, for example, a predetermined amount of a certain packet service high-order modulation channel is 1. 8dB, only 1. 5dB is allocated to the channel.
5204 , 判断在当前时隙该功放是否还有功率剩余;  5204, determining whether the power amplifier has power remaining in the current time slot;
如果在分配给某一分组业务高阶调制信道后, 还有功率剩余, 则执行 S204 ; 如果没有功率剩余, 则结束流程。  If there is power remaining after being assigned to a packet-oriented high-order modulation channel, then S204 is performed; if there is no power remaining, the flow is terminated.
5205 , 判断是否还有其他分组业务高阶调制信道;  5205, determining whether there are other high-order modulation channels of the packet service;
如果当前时隙还有其他分组业务高阶调制信道, 则可以将共享剩余功 率进一步进行分配, 即继续执行 S203及其后续步骤, 直到共享剩余功率分 配完毕或者轮询完所有分组业务高阶调制信道; 如果当前时隙没有其他分 组业务高阶调制信道, 则结束流程。 If there are other packet service high-order modulation channels in the current time slot, the shared residual power can be shared. The rate is further allocated, that is, the process proceeds to S203 and its subsequent steps until the shared remaining power is allocated or all the packet service high-order modulation channels are polled; if there is no other packet service high-order modulation channel in the current time slot, the flow is terminated.
本实施例中, 在采用轮询机制将剩余功率分配给分组业务高阶调制信 道时, 起始分配的分组业务高阶调制信道可以是在多个分组业务高阶调制 信道任意选择的, 也可以是根据信道编码方式或者信道编号顺序选择的, 或者按照 "先到先得" 的顺序, 所谓 "先到先得" 可以理解为, 从当前时 隙需要为之发送功率的信道开始。 本实施例中不做限定。  In this embodiment, when the remaining power is allocated to the packet service high-order modulation channel by using a polling mechanism, the initially allocated packet service high-order modulation channel may be arbitrarily selected in a plurality of packet service high-order modulation channels, or It is selected according to the channel coding mode or the channel number order, or in the order of "first come, first served", so-called "first come, first served" can be understood as starting from the channel for which the current time slot needs to transmit power. This embodiment is not limited.
需要说明的是, 本实施例中, S204和 S205的执行先后顺序可以不做限 定, 也就是说, 可以在还有其他分组业务高阶调制信道的情况下再判断是 否还有剩余功率。  It should be noted that, in this embodiment, the execution order of S204 and S205 may be unrestricted, that is, the remaining power may be further determined if there are other packet service high-order modulation channels.
由上可知, 本实施例中的方法通过轮询的方式(或者也可以理解为遍 历)将功放在当前时隙的剩余功率分配给分组业务高阶调制信道, 从而对 分组业务高阶调制信道进行功率推升, 使功放的功率得到充分地利用, 进 一步地, 使得分组无线业务的链路可以获得载干比增益, 从而使分组无线 业务的性能也得到提升。  As can be seen from the above, the method in this embodiment allocates the remaining power of the power station to the high-order modulation channel of the packet service by means of polling (or can also be understood as traversing), thereby performing the packet service high-order modulation channel. The power is boosted, so that the power of the power amplifier is fully utilized. Further, the link of the packet radio service can obtain the carrier-to-interference ratio gain, thereby improving the performance of the packet radio service.
进一步地, 可以在分配剩余功率时, 可以对各分组业务高阶调制信道 进行差异化处理, 本发明再一实施例提供了一种功率控制方法, 如图 3 所 示, 该方法可以包括:  Further, when the remaining power is allocated, the high-order modulation channel of each packet service may be differentiated. In another embodiment of the present invention, a power control method is provided. As shown in FIG. 3, the method may include:
S301 : 根据功放的最大发射功率和当前时隙各载频对应的信道的总功 率需求确定该功放当前时隙的剩余功率;  S301: Determine, according to a maximum transmit power of the power amplifier and a total power requirement of a channel corresponding to each carrier frequency of the current time slot, a remaining power of the current time slot of the power amplifier;
该步骤的处理过程与图 1所示实施例中 S101基本相同,此处不再赘述。 如果确定出该功放当前时隙的剩余功率大于 0, 执行 S302。  The processing of this step is basically the same as that of S101 in the embodiment shown in FIG. 1, and details are not described herein again. If it is determined that the remaining power of the current time slot of the power amplifier is greater than 0, S302 is performed.
S302: 判断是否存在分组业务高阶调制信道;  S302: Determine whether there is a packet service high-order modulation channel;
在确定功放在当前时隙存在剩余功率时, 可以将判断是否存在分组业 务高阶调制信道, 如果存在, 则可以将剩余功率重分配给分组业务高阶调 制信道, 如果只有一个分组业务高阶调制信道, 直接根据其预定额度将剩 余功率分配给该信道即可, 如果有多于一个分组业务高阶调制信道, 则可 以根据各分组业务高阶调制信道的优先级对剩余功率进行分配, 即执行When it is determined that there is remaining power in the current time slot, it may be determined whether there is a packet service high-order modulation channel, and if so, the remaining power may be redistributed to the packet service high-order tone. Channel, if there is only one packet service high-order modulation channel, the remaining power can be directly allocated to the channel according to its predetermined amount. If there is more than one packet service high-order modulation channel, it can be based on each packet service high-order modulation channel. Priority is assigned to the remaining power, ie execution
S303 , 从而可以实现功放功率的动态共享; 而如果不存在分组业务高阶调 制信道, 则不对剩余功率进行重分配。 S303, thereby realizing dynamic sharing of power amplifier power; and if there is no packet service high-order modulation channel, the remaining power is not redistributed.
S303 , 按照分组业务高阶调制信道的优先级顺序, 根据分组业务高阶 调制信道的预定额度, 将共享剩余功率分配给各分组业务高阶调制信道。  S303. Allocate the shared residual power to each packet service high-order modulation channel according to a predetermined priority of the packet service high-order modulation channel according to a predetermined priority of the packet service high-order modulation channel.
该步骤中, 可以根据分组业务高阶调制信道的信道质量确定分组业务 高阶调制信道的优先级, 信道质量越差的优先级越高, 从而可以让信道质 量差的信道优先得到提升, 从而可以获得较好的性能增益; 或者, 也可以 根据分组业务高阶调制信道上承载业务的优先级确定分组业务高阶调制信 道的优先级, 承载的业务的优先级越高, 其对应的分组业务高阶调制信道 的优先级越高, 从而可以获得更好的性能增益。 此外, 还可以根据实际情 况, 采用其他的方式来确定分组业务高阶调制信道的优先级。  In this step, the priority of the packet service high-order modulation channel can be determined according to the channel quality of the packet-oriented high-order modulation channel, and the higher the channel quality is, the higher the priority is, so that the channel with poor channel quality can be preferentially improved, thereby Obtaining a better performance gain; or determining the priority of the packet service high-order modulation channel according to the priority of the bearer service on the high-order modulation channel of the packet service, and the higher the priority of the carried service, the higher the corresponding packet service. The higher the priority of the order modulation channel, the better performance gain can be obtained. In addition, other methods may be used to determine the priority of the packet service high-order modulation channel according to the actual situation.
而在分配剩余功率时, 从优先级最高的分组业务高阶调制信道开始分 配, 根据该分组业务高阶调制信道的预定额度, 可以以满额或者不满额的 方式将共享剩余功率分配给该分组业务高阶调制信道, 当给该优先级最高 的分组业务高阶调制信道分配结束后, 如果还有功率剩余, 则给下一个优 先级次高的分组业务高阶调制信道进行满额或者不满额的分配, 依此类推, 直至共享剩余功率分配完毕或者直至满足所有分组业务高阶调制信道的预 定额度。  And when the remaining power is allocated, the allocation is started from the highest-order modulation channel with the highest priority, and according to the predetermined amount of the high-order modulation channel of the packet service, the shared residual power may be allocated to the packet service in a full or dissatisfied manner. The high-order modulation channel, after the allocation of the highest-order modulation channel with the highest priority packet service ends, if there is still power remaining, the full-priority packet traffic high-order modulation channel is allocated full or dissatisfied. And so on, until the shared residual power is allocated or until a predetermined amount of high-order modulation channel for all packet services is met.
由上可知, 本实施例中的方法根据分组业务高阶调制信道的优先级将 功放在当前时隙的剩余功率分配给分组业务高阶调制信道, 对分组业务高 阶调制信道实现差异化处理, 使优先级高的分组业务高阶调制信道的功率 优先得到提升, 从而可以获得更好的性能增益等, 并且使功放的功率得到 充分地利用, 进一步地, 使得分组无线业务的链路可以获得载干比增益, 从而使分组无线业务的性能也得到提升。 It can be seen that the method in this embodiment allocates the remaining power of the current time slot to the high-order modulation channel of the packet service according to the priority of the high-order modulation channel of the packet service, and implements differentiated processing on the high-order modulation channel of the packet service. The power priority of the high-order modulation channel of the packet service with high priority is improved, so that better performance gain and the like can be obtained, and the power of the power amplifier is fully utilized, and further, the link of the packet radio service can be obtained. Dry ratio gain, As a result, the performance of packet radio services is also improved.
