图1示出了本发明实施例的无线通信中调整功率的方法100的示意性流程图。如图1所示，该方法100包括：FIG. 1 shows a schematic flowchart of amethod 100 for adjusting power in wireless communication according to an embodiment of the present invention. As shown in Figure 1, themethod 100 includes:

步骤110，无线接入点确定该无线接入点控制的第一小区的节能负载门限。Step 110, the wireless access point determines the energy-saving load threshold of the first cell controlled by the wireless access point.

步骤120，无线接入点根据该节能负载门限控制第一小区的发射功率，该第一小区的发射功率包括数据信道的发射功率。Step 120, the wireless access point controls the transmit power of the first cell according to the energy saving load threshold, where the transmit power of the first cell includes the transmit power of the data channel.

具体地，在步骤110中，一个无线接入点可以只有一个小区，也可以有多个小区，因此第一小区可以表示一个或多个上述无线接入点控制的小区，某个小区的负载可以用该小区内的用户设备所需的无线资源与该小区所有无线资源的比例表示。Specifically, instep 110, a wireless access point may have only one cell or multiple cells, so the first cell may represent one or more cells controlled by the above-mentioned wireless access point, and the load of a certain cell may be It is expressed by the ratio of the radio resources required by the user equipment in the cell to all the radio resources in the cell.

可选地，作为本发明一个实施例，无线接入点确定该无线接入点控制的第一小区的节能负载门限包括：无线接入点获取第一小区在当前周期内的负载信息；无线接入点根据第一小区在当前周期内的负载信息确定第一小区在下一周期内的节能负载门限。Optionally, as an embodiment of the present invention, the wireless access point determining the energy-saving load threshold of the first cell controlled by the wireless access point includes: the wireless access point acquiring load information of the first cell in the current period; The in point determines the energy-saving load threshold of the first cell in the next period according to the load information of the first cell in the current period.

具体地，第一小区发射功率的调整是基于第一小区的节能负载门限进行的调整，如果节能负载门限值设置的过高，会影响用户设备的接入，而节能负载门限值设置的过低，将会影响节能的效果。因此需要根据用户的业务分布来设置节能负载门限，即基于小区的负载情况设置节能负载门限。应理解，小区负载的定义为服务用户设备所需的无线资源与所有无线资源之间的比例。Specifically, the adjustment of the transmit power of the first cell is based on the energy-saving load threshold of the first cell. If the energy-saving load threshold is set too high, the access of the user equipment will be affected, and the energy-saving load threshold is set If it is too low, the effect of energy saving will be affected. Therefore, the energy-saving load threshold needs to be set according to the service distribution of the user, that is, the energy-saving load threshold is set based on the load situation of the cell. It should be understood that the definition of the cell load is the ratio between the radio resources required to serve the user equipment and all the radio resources.

应理解，无线接入点获取第一小区负载信息的当前周期或下一周期的长度可以根据该第一小区的负载变化情况确定，第一小区的负载信息可以是第一小区在该周期内的平均负载，本发明不限于此。It should be understood that the length of the current cycle or the next cycle for the wireless access point to obtain the load information of the first cell may be determined according to the load change of the first cell, and the load information of the first cell may be the load information of the first cell in the cycle. Average load, the present invention is not limited to this.

还应理解，无线接入点获取第一小区负载信息的当前周期或下一周期的长度可以根据该第一小区的负载变化情况确定，例如可以将当前周期或下一周期设置为小区负载变化周期，上述下一周期是指在当前周期之后的一段时长，其长度可以跟当前周期相同也可以不相同，第一小区的负载信息可以是第一小区在该周期内的平均负载，本发明不限于此。具体而言，第一小区在下一周期的节能负载门限可以根据当前周期的负载门限进行确定，从而能够根据系统负载的动态变化，进行与之对应的小时间粒度的节能控制，进一步地实现分布式高效控制。It should also be understood that the length of the current cycle or the next cycle for the wireless access point to obtain the load information of the first cell can be determined according to the load change situation of the first cell, for example, the current cycle or the next cycle can be set as the cell load change cycle. , the above-mentioned next cycle refers to a period of time after the current cycle, and its length may be the same as or different from the current cycle. The load information of the first cell may be the average load of the first cell in the cycle. The present invention is not limited to this.

应理解，该控制器可以位于某个无线接入点，也可以独立于任何一个无线接入点之外作为一个独立的网络设备。It should be understood that the controller may be located at a certain wireless access point, or may be independent of any wireless access point as an independent network device.

可选地，该控制器可以统一配置各个无线接入点的节能负载门限值，也就是说可以统一配置各个小区的节能负载门限值，具体步骤如下：控制器获取第一周期内所有小区的负载的均衡值；控制器获取网络负载均衡的目标值，该目标值可以基于运营商策略得到，也可以基于无线接入点的接入控制门限来设置，本发明不限于此；控制器根据负载均衡值和负载均衡目标值的平滑平均值确定为每个无线接入点的节能负载门限，并该将节能负载门限发送给各个无线接入点，以便于各个无线接入点根据该节能负载门限进行统一配置。Optionally, the controller can uniformly configure the energy-saving load threshold of each wireless access point, that is to say, can uniformly configure the energy-saving load threshold of each cell, and the specific steps are as follows: the controller obtains all cells in the first period. The controller obtains the target value of network load balancing, the target value can be obtained based on the operator's policy, or can be set based on the access control threshold of the wireless access point, the present invention is not limited to this; The smoothed average value of the load balance value and the load balance target value is determined as the energy-saving load threshold of each wireless access point, and the energy-saving load threshold is sent to each wireless access point, so that each wireless access point can determine the energy-saving load threshold according to the energy-saving load threshold. The threshold is configured uniformly.

具体地，控制器根据各个小区当前周期的负载均值和网络负载均衡目标值确定节能负载门限，可以根据公式(1)计算该节能负载门限值，公式(1)如下：Specifically, the controller determines the energy-saving load threshold according to the current cycle load average of each cell and the network load balancing target value, and can calculate the energy-saving load threshold according to formula (1), and formula (1) is as follows:

ρ_thr＝αρ_avg+(1-α)ρ_tar (1)ρ_thr = αρ_avg +(1-α)ρ_tar (1)

可选地，作为本发明一个实施例，无线接入点根据第一小区在当前周期内的负载信息确定第一小区在下一周期内的节能负载门限包括：无线接入点根据第一小区在上一周期内的负载信息以及第一小区在当前周期的负载信息，确定第一小区的当前负载变化量；无线接入点获取网络负载均衡目标值；无线接入点根据第一小区的负载变化量和负载均衡目标值确定所述第一小区的节能负载门限。Optionally, as an embodiment of the present invention, the wireless access point determining the energy-saving load threshold of the first cell in the next cycle according to the load information of the first cell in the current cycle includes: The load information in one period and the load information of the first cell in the current period determine the current load variation of the first cell; the wireless access point obtains the target value of network load balancing; the wireless access point determines the load variation of the first cell according to the load variation of the first cell and the load balancing target value to determine the energy saving load threshold of the first cell.

具体地，无线接入点可以单独配置第一小区的节能负载门限，具体地，例如单独配置第一小区的节能负载门限时，具体步骤如下：统计第一小区第一周期内负载和负载变化趋势；获取全网负载均衡的目标值，具体获取全网负载均衡的目标值的方式可以为通过网络管理系统获取，或通过控制器获取或查表获取。负载小于全网负载均衡的目标值的无线接入点，根据公式(2)确定节能负载门限值，公式(2)如下：Specifically, the wireless access point can individually configure the energy-saving load threshold of the first cell. Specifically, for example, when the energy-saving load threshold of the first cell is independently configured, the specific steps are as follows: Count the load and load change trend of the first cell in the first period ; Obtain the target value of the entire network load balancing, and the specific method of obtaining the target value of the entire network load balancing can be obtained through the network management system, or obtained through the controller or table lookup.

Δρ_tar为系统预设的门限，可以设为10％。sign(Δρ_i)为小区i的负载变化的趋势，当负载变小时，取值为-1，变大时取值为+1，否则取值为0。当小区的负载变小时，节能负载门限在全网负载均衡的目标值之上，幅度为预设门限；反之，节能负载门限在全网负载均衡的目标值之下，幅度为预设门限。Δρ_tar is a preset threshold of the system, which can be set to 10%. sign(Δρ_i ) is the trend of the load change of the cell i. When the load becomes smaller, the value is -1; when the load becomes larger, the value is +1; otherwise, the value is 0.

具体地，无线接入点可以根据实际情况选择不同时刻测量第一小区当前的负载情况，若第一小区在第一时刻测得的当前负载小于节能负载门限时，则该无线接入点可以根据第一小区的当前发射功率，确定第一小区的发射功率的降低幅度，具体地，可以根据公式(3)确定功率调整的幅度，公式(3)如下所示：Specifically, the wireless access point can select different times to measure the current load of the first cell according to the actual situation. If the current load measured by the first cell at the first moment is less than the energy-saving load threshold, the wireless access point can The current transmission power of the first cell determines the reduction range of the transmission power of the first cell. Specifically, the power adjustment range can be determined according to formula (3), and formula (3) is as follows:

其中，p_n,i为第i个小区当前的发射功率，ρ_n,i和ρ_thr,i分别为第i个小区当前的测量负载和节能负载门限。Among them, p_n,i is the current transmit power of the ith cell, and ρ_n,i and ρ_thr,i are the current measurement load and energy-saving load threshold of the ith cell, respectively.

应理解，无线接入点继续测量第二时刻第一小区的当前负载，当第一小区在第二时刻的当前负载小于节能负载门限时，继续根据第一小区的发射功率的降低幅度，执行第一小区当前的发射功率的降低操作，其中，第二时刻发生在第一时刻之后。It should be understood that the wireless access point continues to measure the current load of the first cell at the second moment, and when the current load of the first cell at the second moment is less than the energy-saving load threshold, it continues to execute the first cell according to the reduction range of the transmit power of the first cell. A reduction operation of the current transmit power of a cell, wherein the second time instant occurs after the first time instant.

应理解，当第一小区的当前发射功率与第一小区的发射功率的降低幅度之和大于功率最低门限值时，才执行第一小区的发射功率的降低操作。It should be understood that the operation of reducing the transmit power of the first cell is performed only when the sum of the current transmit power of the first cell and the reduction range of the transmit power of the first cell is greater than the minimum power threshold value.

具体地，可以根据公式(4)确定调整后的发射功率，公式(4)如下式所示：Specifically, the adjusted transmit power can be determined according to formula (4), and formula (4) is shown in the following formula:

p_n+1,i＝Δp_n+1,i+p_n,i (4)p_n+1,i =Δp_n+1,i +p_n,i (4)

本发明实施例提供的方法可以动态调整发射功率，能够适应负载的动态变化，低负载的小区的发射功率降低后，能够降低能耗，同时减小对其它小区或无线接入点的干扰，同时能够降低其它高负载的无线接入点的负载，全网负载趋于均衡。The method provided by the embodiment of the present invention can dynamically adjust the transmission power, and can adapt to the dynamic change of the load. After the transmission power of the low-load cell is reduced, the energy consumption can be reduced, and the interference to other cells or wireless access points can be reduced at the same time. It can reduce the load of other high-load wireless access points, and the load of the whole network tends to be balanced.

可选地，作为本发明一个实施例，上述第一小区的发射功率还包括控制信道的发射功率。Optionally, as an embodiment of the present invention, the transmit power of the first cell further includes the transmit power of the control channel.

具体地，当控制信道和数据信道分开的情况下，仅仅调整数据信道的发射功率不会对控制信道有影响，因此不会改变用户设备与各个小区之间的关联关系；当对于数据信道和控制信道相统一的情况下，例如无线局域网中，调整数据信道的功率同时也是对控制信道的调整，也就是说本发明实施例还用于对控制信道发射功率节能的情况。Specifically, when the control channel and the data channel are separated, only adjusting the transmit power of the data channel will not affect the control channel, so the association between the user equipment and each cell will not be changed; When the channels are unified, for example, in a wireless local area network, adjusting the power of the data channel is also the adjustment of the control channel, that is to say, the embodiment of the present invention is also used to save energy on the transmit power of the control channel.

可选地，作为本发明一个实施例，上述方法还包括：无线接入点将根据第一小区的发射功率的降低幅度，确定第一小区的偏移参数；向用户设备发送小区的偏移参数，以用于用户设备根据该偏移参数进行小区重选操作。Optionally, as an embodiment of the present invention, the above method further includes: the wireless access point determines the offset parameter of the first cell according to the reduction range of the transmit power of the first cell; and sends the offset parameter of the cell to the user equipment , for the user equipment to perform a cell reselection operation according to the offset parameter.

具体地，可以根据公式(5)确定第一小区的偏移量，公式(5)如下式所示：Specifically, the offset of the first cell can be determined according to formula (5), and formula (5) is as follows:

Offset_n+1,i＝-Δp_n+1,i (5)Offset_n+1,i =-Δp_n+1,i (5)

其中，Offset_n+1,i为本次调整后的小区偏移量，Δp_n+1,i为无线接入点i当前的功率降低幅度。Wherein, Offset_n+1,i is the cell offset after this adjustment, and Δp_n+1,i is the current power reduction range of the wireless access point i.

本发明实施例提供的方法可以把小区偏移参数发送给用户设备，以使得用户设备保持同样的用户关联，减少没有必要的切换。The method provided by the embodiment of the present invention can send the cell offset parameter to the user equipment, so that the user equipment maintains the same user association and reduces unnecessary handovers.

可选地，作为本发明一个实施例，当用户设备收到无线接入点发送的小区偏移参数时，需要根据小区偏移参数进行小区重选操作。Optionally, as an embodiment of the present invention, when the user equipment receives the cell offset parameter sent by the wireless access point, it needs to perform a cell reselection operation according to the cell offset parameter.

具体地，用户设备在小区的选择、重选或驻留时，通常选择接收信号强度最大的小区。当服务小区的控制信道功率调整时，在该小区内的用户设备将根据收到的小区偏移参数进行如下的调整，如公式(6)所示：Specifically, during cell selection, reselection, or camping, the user equipment usually selects the cell with the highest received signal strength. When the control channel power of the serving cell is adjusted, the user equipment in the cell will perform the following adjustment according to the received cell offset parameter, as shown in formula (6):

其中，RSRP为参考信号接收强度(英文：Reference Signal Received Power，简写：RSRP)，也就是说用户设备将选取参考信号接收强度与小区偏移参数的和最大的小区为服务小区。Wherein, RSRP is Reference Signal Received Power (English: Reference Signal Received Power, abbreviated: RSRP), that is to say, the user equipment will select the cell with the largest sum of the reference signal received strength and the cell offset parameter as the serving cell.

具体地，用户设备在进行切换决策时，也依赖于接收到的服务小区和邻区的信号的变化，这时也需要在考虑小区偏移参数，本发明不限于此。Specifically, when the user equipment makes a handover decision, it also depends on the received signal changes of the serving cell and the neighboring cell, and the cell offset parameter also needs to be considered at this time, and the present invention is not limited to this.

图2是本发明实施例提供的无线通信中调整功率的方法的示意性流程图。如图2所示，该方法包括：FIG. 2 is a schematic flowchart of a method for adjusting power in wireless communication according to an embodiment of the present invention. As shown in Figure 2, the method includes:

步骤210，基于用户业务的分布统计，确定每个无线接入点的节能负载门限。Step 210: Determine the energy-saving load threshold of each wireless access point based on the distribution statistics of user services.

步骤220，当前负载低于节能负载门限的无线接入点，调整无线接入点的发射功率。Step 220, the wireless access point whose current load is lower than the energy saving load threshold adjusts the transmit power of the wireless access point.

步骤230，当前负载低于节能负载门限的无线接入点，根据无线接入点的发射功率确定小区偏移参数，并将该偏移参数发送给用户设备。Step 230, the wireless access point whose current load is lower than the energy saving load threshold determines the cell offset parameter according to the transmit power of the wireless access point, and sends the offset parameter to the user equipment.

步骤240，用户设备基于该小区的偏移参数进行小区的选择、驻留或者切换。Step 240, the user equipment performs cell selection, camping or handover based on the offset parameter of the cell.

在步骤210中，每个无线接入点可以单独配置节能负载门限，也可以由某个无线接入点或者控制器进行统一配置，本发明不限于此。Instep 210, each wireless access point may individually configure the energy-saving load threshold, or may be uniformly configured by a certain wireless access point or a controller, but the present invention is not limited thereto.

具体地，由控制器统一设置各无线接入点的节能负载门限的步骤如下：Specifically, the steps of uniformly setting the energy-saving load threshold of each wireless access point by the controller are as follows:

1)每个无线接入点周期统计其负载，并向控制器上报；1) Each wireless access point periodically counts its load and reports it to the controller;

2)控制器计算所有无线接入点的负载的均值ρ_avg；2) The controller calculates the mean value ρ_avg of the loads of all wireless access points;

3)控制器获取网络负载均衡的目标值ρ_tar，该目标值可以基于运营商的策略，也可以基于无线接入点的接入控制门限来设置；3) The controller obtains the target value ρ_tar of network load balancing, and the target value can be set based on the policy of the operator or the access control threshold of the wireless access point;

4)控制器确定负载均值和负载均衡目标值的平滑平均值为每个无线接入点的节能负载门限：4) The controller determines the load average value and the smoothed average value of the load balancing target value as the energy saving load threshold for each wireless access point:

ρ_thr＝αρ_avg+(1-α)ρ_tarρ_thr =αρ_avg +(1-α)ρ_tar

其中，α为平滑系数，可以设为0.5，ρ_thr为无线接入点的节能负载门限，在该控制器下的所有无线接入点统一设置。Among them, α is a smoothing coefficient, which can be set to 0.5, and ρ_thr is the energy-saving load threshold of the wireless access point, which is set uniformly for all wireless access points under the controller.

具体地，由各无线接入点单独配置节能负载门限的步骤如下：Specifically, the steps for individually configuring the energy-saving load threshold by each wireless access point are as follows:

1)每个无线接入点周期统计其负载和负载变化趋势：1) Each wireless access point periodically counts its load and load change trend:

Δρ_i＝ρ_cur,i-ρ_prv,iΔρ_i =ρ_cur,i -ρ_prv,i

其中，ρ_cur,i和ρ_prv,i分别为无线接入点i当前的负载和上次统计的负载；Among them, ρ_cur,i and ρ_prv,i are the current load and the last statistical load of wireless access point i respectively;

2)获取全网负载均衡的目标值ρ_tar；2) Obtain the target value ρ_tar of the entire network load balancing;

3)负载小于全网负载均衡的目标值的无线接入点，确定其节能负载门限：3) For wireless access points whose load is less than the target value of load balancing in the entire network, determine the energy-saving load threshold:

ρ_thr,i＝ρ_tar-ρ_tarsign(Δρ_i)Δρ_tarρ_thr,i =ρ_tar -ρ_tar sign(Δρ_i )Δρ_tar

其中，Δρ_tar为系统预设的门限，可以设为10％。sign(Δρ_i)为无线接入点i的负载变化的趋势，当负载变小时，取值为-1，变大时取值为+1，否则取值为0。当无线接入点的负载变小时，节能负载门限在全网负载均衡的目标值之上，幅度为预设门限；反之，节能负载门限在全网负载均衡的目标值之下，幅度为预设门限。Among them, Δρ_tar is a threshold preset by the system, which can be set to 10%. sign(Δρ_i ) is the trend of the load change of the wireless access point i. When the load becomes smaller, the value is -1; when the load becomes larger, the value is +1; otherwise, the value is 0. When the load of the wireless access point becomes smaller, the energy-saving load threshold is above the target value of the network-wide load balancing, and the amplitude is the preset threshold; otherwise, the energy-saving load threshold is below the target value of the network-wide load balancing, and the amplitude is the preset threshold. threshold.

在步骤220，具体地，每个无线接入点调整发射功率的步骤如下：Instep 220, specifically, the steps of adjusting the transmit power of each wireless access point are as follows:

1)每个无线接入点测量其负载；1) Each wireless access point measures its load;

2)如果测量负载小于节能负载门限，则继续参与功率调整，否则不再调整；2) If the measured load is less than the energy-saving load threshold, continue to participate in the power adjustment, otherwise it will not be adjusted;

3)确定功率调整的幅度；3) Determine the magnitude of power adjustment;

4)基于幅度进行功率调整，其中，若调整后的功率大于功率最低门限，并且测量负载小于节能负载门限，则继续调整，否则不再调整；4) Adjusting the power based on the amplitude, wherein, if the adjusted power is greater than the minimum power threshold and the measured load is less than the energy-saving load threshold, continue to adjust, otherwise, no further adjustment;

功率最低门限是为了保证一定的网络覆盖和服务质量(英文：Quality ofService简写：QoS)要求，在密集网场景下，最低门限可以设置很小；The minimum power threshold is to ensure a certain network coverage and quality of service (English: Quality of Service abbreviation: QoS) requirements. In dense network scenarios, the minimum threshold can be set to a small value;

5)无线接入点把新的小区偏移参数发给用户，以保持同样的用户关联，减少没必要的切换。5) The wireless access point sends the new cell offset parameter to the user to maintain the same user association and reduce unnecessary handovers.

在步骤240中，当用户收到无线接入点发送的小区偏移参数时，需要及时应用。一般来说，涉及到功率域的操作，如小区重选，切换决策等，都需要做相应的调整，具体而言，用户可以进行以下操作：Instep 240, when the user receives the cell offset parameter sent by the wireless access point, it needs to be applied in time. Generally speaking, operations related to the power domain, such as cell reselection, handover decision, etc., need to be adjusted accordingly. Specifically, users can perform the following operations:

1)小区重选1) Cell reselection

用户在小区选择/重选/驻留时，通常选择接收信号强度最大的小区。当服务小区的导频功率调整时，在该小区的用户会收到小区偏移参数，这时，小区选择如下：During cell selection/reselection/camping, the user usually selects the cell with the highest received signal strength. When the pilot power of the serving cell is adjusted, the users in the cell will receive the cell offset parameter. At this time, the cell selection is as follows:

2)切换决策2) Switching decision

切换决策也是涉及功率域的操作，依赖于接收到的服务小区和邻区的信号的变化，这时同样需要加上小区偏移量。The handover decision is also an operation involving the power domain, which depends on the received signal changes of the serving cell and the neighboring cells, and the cell offset also needs to be added at this time.

步骤304，基于功率调整幅度进行功率调整。Step 304: Perform power adjustment based on the power adjustment range.

步骤305，判断调整后的发射功率是否大于最低门限功率。如果调整后的发射功率不高于最低门限功率则结束功率调整；如果调整后的发射功率高于最低门限功率，则进一步判断当前负载是否还小于节能负载门限，如果此时当前负载小于节能负载门限，则继续进行发射功率的调整。Step 305, judging whether the adjusted transmit power is greater than the minimum threshold power. If the adjusted transmit power is not higher than the minimum threshold power, the power adjustment is ended; if the adjusted transmit power is higher than the minimum threshold power, it is further judged whether the current load is still less than the energy-saving load threshold, and if the current load is less than the energy-saving load threshold at this time , then continue to adjust the transmit power.

在步骤303中，需要确定每次功率调整的幅度。具体地，可以根据公式(3)确定功率调整的幅度，公式(3)如下所示：In step 303, the magnitude of each power adjustment needs to be determined. Specifically, the magnitude of the power adjustment can be determined according to formula (3), and formula (3) is as follows:

其中，p_n,i为第i个小区当前的发射功率，ρ_n,i和ρ_thr,i分别为第i个小区当前的测量负载和节能负载门限。Among them,_pn,i is the current transmit power of the i-th cell, and ρ_n,i and ρ_thr,i are the current measurement load and energy-saving load threshold of the i-th cell, respectively.

在步骤304中，基于功率调整幅度进行功率调整。具体地，可以根据公式(4)确定调整后的发射功率，公式(4)如下式所示：In step 304, power adjustment is performed based on the power adjustment magnitude. Specifically, the adjusted transmit power can be determined according to formula (4), and formula (4) is shown in the following formula:

p_n+1,i＝Δp_n+1,i+p_n,i (4)p_n+1,i =Δp_n+1,i +p_n,i (4)
