Description

Power adjustment method and device Technical field

The present invention relates to mobile communication technologies, and in particular, to a power adjustment method and apparatus.

Background technique

UMTS (Universal Mobile Telecommunications System) is one of the global 3G standards developed by the 3GPP (3rd Generation Partnership Project). WCDMA (Wideband Code Division Multiple Access) is one of the mainstream technologies of the third generation mobile communication system. It is applied in the early versions of UMTS, and HSDPA (High Speed Downlink Packet Access) was introduced in later versions. The high-speed downlink packet access technology is used to improve the downlink data transmission rate, and the HSUPA (High Speed Uplink Packet Access) technology is used to improve the uplink data transmission rate and reduce the user data transmission delay. In order to allow users to have a better experience in the UMTS network.

In UMTS, in order to overcome the influence of channel attenuation and maintain a stable reception quality of the received signal, a power control method is employed. In the power control method, in order to implement power control on the uplink channel, a TPC (Transmission Power Control) command is used to control the uplink transmit power of the UE, where the TPC command is transmitted on the downlink channel, and when the UE receives When the TPC command is used, the TPC command is parsed, and the power control algorithm used by the TPC command is used to indicate that the uplink transmit power is increased or the uplink transmit power is decreased.

The TPC commands in different wireless links may use different power control algorithms. For example, the power control algorithm used on the wireless link may include:

The first power control algorithm: receives the TPC command in each time slot of one cycle, and hard-checks the TPC command, and determines the power control result according to the result of the hard decision of the multiple TPC commands in the cycle.

The second power control algorithm: receives the TPC command in a specific time slot of each cycle, and adjusts the power according to the indication of the TPC command after receiving the TPC command.

The third power control algorithm: receives the TPC command in each time slot of one cycle, wherein the TPC commands in the same cycle are all the same, and the TPC commands received in the cycle are merged to determine the work. Rate control results.

For a UE, when it only establishes one radio link, it can directly perform power control according to the power control algorithm adopted by the TPC command. When a UE establishes multiple radio links, especially when at least one radio link uses the second power control algorithm, since the power adjustment is performed after receiving the TPC command in the second power control algorithm, There is a problem that the power adjustment is too frequent.

detailed description

In the mobile communication network, in order to overcome the influence of channel attenuation and maintain a stable reception quality of the received signal, a power control method is adopted.

The power control is divided into inner loop power control and outer loop power control, wherein the inner loop power control measures the reception quality of the channel, such as the received signal to interference ratio (SIR) (Signal to Interference Rate) / SNR (Signal to Noise Rate, SNR (Signal to Interference and Noise Rate), etc., and compare the measured channel reception quality with the set target value, and generate a TPC command according to the result of the comparison, which is indicated by the TPC command. "Upload transmit power" or "reduced transmit power" so that the channel reception quality reaches the target value.

The outer loop power control adjusts the target value according to the block error rate/bit error rate/error symbol rate of the channel, so that the block error rate/bit error rate/error symbol rate of the channel reaches a desired value.

The channel used by the UE to transmit data to the base station is referred to as an uplink channel, and the channel in which the UE receives data transmitted by the base station is referred to as a downlink channel. The inner loop power control may be further divided into uplink inner loop power control and downlink inner loop power control according to different power control channels, wherein inner loop power control performed on the uplink channel is referred to as uplink inner loop power control.

The TPC command used in the uplink inner loop power control is called an uplink TPC. The command is generated according to the quality measurement of the uplink channel, and is transmitted on the downlink channel, and is used to indicate that the UE “uplifts the uplink transmit power” or “decreases the uplink transmit power. Or "Keep the uplink transmit power."

The process of the uplink inner loop power control generally includes: the base station measures the reception quality of the uplink DPCCH (Dedicated Physical Control Channel), and compares the measured value with the set target value to generate an uplink TPC command. Upstream TPC commands pass the downstream DPCCH Or the downlink F-DPCH (Fractional Dedicated Physical Channel) is sent to indicate that the UE raises or lowers the uplink DPCCH transmission power.

The uplink DPCCH includes a pilot domain and a TPC domain, and the pilot in the pilot domain is used for uplink channel estimation and measurement, and the TPC command in the TPC domain is a downlink TPC. The downlink DPCCH includes a pilot domain and a TPC domain, and the pilot in the pilot domain is used for downlink channel estimation and measurement, and the TPC in the TPC domain is an uplink TPC. The downlink F-DPCH has only the TPC domain, and the TPC in the TPC domain is the uplink TPC, which is equivalent to the simplified channel of the downlink DPCCH.

The power control algorithms used in the uplink inner loop power control can be divided into a fast power control algorithm and a slow power control algorithm. Among them, several commonly used slow power control algorithms include:

The first power control algorithm: the base station sends an uplink TPC command in each time slot, and the UE receives the TPC command and hardly judges in each time slot. If the hard decision result of the TPC command received by the UE is the same in one cycle (for example, the time is M time slot), the result of the decision of the uplink TPC command is valid, for example, the UE receives in one cycle. If the judgment result of the TPC command is the rising power, the transmission power of the UE is raised, and for example, if the judgment result of the TPC command received by the UE in one adjustment period is the reduced power, the transmission power of the UE is reduced; If the hard decision result of multiple TPC commands received by the UE is different, the DPCCH transmission power is kept unchanged.

The second power control algorithm: the base station sends an uplink TPC command in one cycle (for example, the time of the M time slots), that is, the uplink TPC command is sent in only one time slot in one cycle, and the TPC command is not sent in other time slots. After receiving the uplink TPC, the UE performs a hard decision and adjusts the power according to the result of the hard decision. The adjusted time may be a preset time after the time slot of the TPC is received, or may be a preset after the end of the current cycle. Set the time to execute again. In this manner, the UE adjusts the uplink DPCCH transmission power every M time slots.

The third power control algorithm: the base station sends a TPC command in each time slot of a period, wherein the TPC commands of the same period are all the same, the UE combines the TPC commands received in one cycle, and performs hard decision, the UE The transmission power is adjusted according to the result of the hard decision.

The above-mentioned inner loop power control algorithms are all for a single radio link. When the UE is in the coverage of multiple cells, multiple radio links may be established simultaneously with multiple cells, for example, during the soft handover process of the UE. At the same time, the communication link is maintained with both the original cell and the new cell, and the connection with the original cell is disconnected only after the UE establishes stable communication in the new cell.

When the UE establishes multiple radio links at the same time, the UE transmits on multiple links in one cycle. The TPC command, if the UE performs power adjustment according to the TPC command on each link, the following may occur: (1) The power adjustment results generated by multiple links are different, such as the TPC command with both raised power and reduced power. The UE may have a power adjustment contradiction; (2) the power adjustment time of the TPC command used by each link is different. For example, the TPC adopting the second power control algorithm may perform power adjustment after receiving the TPC command, and adopts the 1. The TPC command of the third power control algorithm is adjusted at least at the end of the current period, so that the UE may need to perform multiple power adjustments in one cycle, especially when the TPC commands of multiple links adopt the second power. When the algorithm is controlled, the TPC command of the second power control algorithm may fall in each time slot in the same period, which may cause the UE to frequently adjust power and affect normal communication of the UE.

It can be seen that how to properly process the TPC commands on each link when the UE establishes multiple links becomes a problem in UE power adjustment.

In order to solve the problem of the TPC command processing on each link of the UE, a method for performing screening and combining processing on the TPC commands on each link is proposed in the embodiment of the present invention.

Considering the first power control algorithm and the third power control algorithm, the power adjustment result is determined in the last time slot of one cycle, and the power adjustment is performed within a preset time after the end of the current cycle, therefore, when the UE chain When the TPC commands on the road adopt the first power control algorithm, the third power control algorithm, or the first power control algorithm and the third power control algorithm, the following methods can be used to filter the TPC commands on each link. Processing, specific:

(1) The UE performs a hard decision on the TPC command on each link according to the algorithm used by the TPC command on each link in the last time slot of a cycle to obtain the intermediate amount TPC_temp of the N uplink TPC commands. Then, the N TPC_temps are processed as follows:

a. When there is a power-down TPC command in the N TPC_temps, it is determined to be a power reduction;

b. When the number of the power-up TPC commands in the _N TPC_temp is greater than the number of the power-up TPC commands, it is determined to be the boost power, otherwise, it is determined to maintain the power. The specific calculation can be calculated by the following formula:

时，Among them, when

Time,

Determined to increase power, otherwise determined to reduce power.

When the UE is in the soft handover area, the effective time of the uplink power control algorithm and the uplink power control algorithm of the third power control algorithm are both after the last time slot of the current period, so the UE is in the soft handover area. When the first power control algorithm or the third power control algorithm is configured, the UE can perform the processing in the above manner.

However, when the TPC command of at least one link in the UE uses the second power control algorithm, the TPC command of the second power control algorithm can take effect in the time slot after receiving the TPC command, without waiting When the current period is completed, it can be seen that the effective time of the TPC command of the second power control algorithm is different from the first power control algorithm and the third power control algorithm, so when the TPC command of at least one link in each link of the UE is adopted, When the second power control algorithm is used, the UE can no longer process the TPC commands on the links according to the foregoing manner. If the foregoing processing mode is adopted, the TPC commands of the second power control algorithm are separately determined and executed. Since the TPC command using the second power control algorithm may exist in each time slot of the current period, the UE may need to frequently adjust the transmission power in multiple time slots, which not only increases the power consumption of the UE, but may also affect the UE. Normal communication service.

The embodiment of the present invention provides a power adjustment method. When a TPC command on at least one link of a UE uses a second power control algorithm, the UE filters and processes the TPC commands on each link. The UE performs power adjustment at most once in one cycle, which solves the problem that the UE may need to frequently adjust the transmission power when the TPC command using the second power control algorithm is included in each link.

FIG. 1 is a schematic flowchart of Embodiment 1 of a power adjustment method according to the present invention. The main body of the method is:

Step S11: Receive a transmission power control TPC command from at least two links, where the TPC command on the at least one link adopts a second power control algorithm.

The UE receives the TPC command from each link, and the TPC command on at least one link adopts the second power control algorithm, which may be classified into the following cases:

(1) Algorithm 2+ Algorithm 2: A second power control algorithm used by the TPC commands on each link of the UE.

(2) Algorithm 1 + Algorithm 2: The power control algorithm adopted by the TPC command on each link of the UE includes a first power control algorithm and a second power control algorithm.

(3) Algorithm 2+ Algorithm 3: The power control algorithm adopted by the TPC command on each link of the UE includes a second power control algorithm and a third power control algorithm.

(4) Algorithm 1 + Algorithm 2+ Algorithm 3: The power control algorithm adopted by the TPC command on each link of the UE includes a first power control algorithm, a second power control algorithm, and a third power control algorithm.

(5) Algorithm 2 and a fourth power control algorithm, where the fourth power control algorithm may be a fast power control algorithm, such as the base station transmitting an uplink TPC command in each time slot, and the UE receiving the TPC command and each The hard decision is made in the time slot, and the UE adjusts the transmission power according to the result of the hard decision in each time slot.

Step S12: Perform screening processing on the TPC commands on each link in an adjustment period to obtain a power adjustment command.

Regardless of the combination of (1), (2), (3), (4), and (5) in step S11, regardless of the TPC command on each link of the UE, the UE is in each of the adjustment periods. The TPC command on the link performs filtering processing to determine the power adjustment command corresponding to the current adjustment period.

The method for the UE to filter the TPC command on each link in an adjustment period may be determined according to actual requirements. For example, it may be determined whether a power-down TPC command is received within an adjustment period, and if a power-down TPC command is received, The power adjustment command may be determined as a power down adjustment command regardless of other TPC commands.

Step S13: Adjust the transmission power according to the power adjustment command.

The UE adjusts the transmit power according to the determined power adjustment command. The specific execution time, the UE may determine according to the time slot in which the power adjustment command is located, for example, in the next time slot in which the power adjustment command is determined. Or, executed within a set time slot after the end of the current adjustment period.

In this embodiment, when the TPC command on each link received by the UE includes the TPC command of the second control algorithm, the UE filters and processes the TPC command on each link in an adjustment period, and determines a power adjustment corresponding to one adjustment period. The command performs power adjustment at most once in an adjustment period, and solves the problem that the power adjustment is too frequent when the TPC command on each link of the UE includes the TPC command of the second control algorithm.

FIG. 2 is a schematic flowchart of Embodiment 2 of a power adjustment method according to the present invention, where an execution subject of the method is a UE.

In this embodiment, the RNC (Radio Network Controller) sets the transmission time of the TPC command of the second power control algorithm on each link of the UE, so that the UE can receive the preset time period of the adjustment period. All TPC commands that use the second power control algorithm. The UE performs a filtering process on the TPC commands on the links according to the TPC commands of the second power control algorithm received in the preset time period, and in combination with the TPC commands of other algorithms, where the TPC commands of other algorithms include but are not limited to The first, second, third and fourth power control calculations described above The specific processing steps of the embodiment will be described in detail below, including:

Step S21: Receive a TPC command from at least two links, where the TPC command on the at least one link adopts a second power control algorithm.

The second power control algorithm is used for the TPC command on at least one of the links of the UE. The algorithm used on the links of the UE may be the same as that in the first embodiment.

Step S22: determining, according to the preset time period in an adjustment period, whether a power reduction TPC command is received, where the preset time period is a fixed transmission time period of the TPC command of the second power control algorithm, and the preset time period is The length is an integer multiple of one slot length; if step S23 is received, otherwise step S24 is performed.

The RNC presets a transmission period of the TPC command of each second power control algorithm. The UE predetermines the transmission time period of the TPC command of the second power control algorithm by using the configuration information of each link, and receives each TPC command that adopts the second power control algorithm in the preset time period. The UE receives the TPC command of the second power control algorithm and also receives the TPC command using other power control algorithms.

The specific preset time period may be the length of one time slot, or may be the length of multiple (such as two or three) time slots, which will not be enumerated here.

The UE determines, according to the received TPC command, whether the power-down TPC command is received, where the determined manner may include:

(1) After the UE completes the preset time period, the UE determines whether it is a power-down TPC command by using each TPC command received from the preset time.

(2) The UE determines whether it is a power-down TPC command every time a TPC command is received within the preset time period. If the power-down TPC command is received, the UE does not perform this judgment on the TPC command received later.

(3) In the determining manner of (1) or (2) above, the UE first determines whether the TPC command of the second power control algorithm is a power-down TPC command, and if the TPC command of the second power control algorithm is a rising power, This determination is made for TPC commands using other power control algorithms.

Step S23: Receive a power reduction TPC command in a preset time period in an adjustment period, and determine that the power adjustment command is a power down adjustment command.

Step S24: In the preset time period, the received TPC commands are all the power-up TPC commands, and the power adjustment command is determined to be a power-up adjustment command.

Step S25: Adjust the transmission power according to the power adjustment command.

In this step, the UE adjusts the transmit power according to the power adjustment command determined in step S23 or step S24.

Specifically, when the UE adjusts the transmit power, the time of the adjustment may be determined according to actual needs, for example, determining the time of the power adjustment by using the preset time period as a reference. Specifically, the preset may be preset after the preset time period is completed. The time slot is adjusted according to the power adjustment command, for example, the transmission power is adjusted in the next time slot after receiving the 512 chips after the preset time period is completed, and the result of the adjustment can be kept down. The secondary power adjustment command is executed before.

In addition to setting the power adjustment time with reference to the preset time period, the adjustment period may be adjusted to determine the time of the power adjustment. Specifically, the UE may adjust the transmission power according to the power adjustment command in the preset time slot after the adjustment period. For example, the transmit power is adjusted at the start position of the next adjustment period after receiving the 512 chips after the end of the adjustment period, wherein the result of the adjustment can be maintained until the next power adjustment command is executed.

In this embodiment, the TPC command that adopts the second power control algorithm is received in the preset time period, and all the TPC commands received in the preset time period are used to determine the power adjustment command, and the current cycle is not required. The TPC command in the time slot is processed in a simple and convenient manner, and the power adjustment is performed at most once in an adjustment period, which can effectively solve the TPC command on each link of the UE, and the power adjustment is too frequent when the TPC command includes the second control algorithm. The problem.

FIG. 3 is a schematic flowchart of Embodiment 3 of a power adjustment method according to the present invention, where an execution body of the method is a UE.

In this embodiment, the RNC sets the transmission time of the TPC command of each second power control algorithm of the UE, so that the UE receives all the TPC commands that adopt the second power control algorithm in the preset time period in the adjustment period, so that the UE can The TPC command of the second power control algorithm received in the time period is combined with the TPC command of the other algorithm to process the TPC command on each link. The specific processing steps of the embodiment are described in detail below, including :

Step S31: Receive a transmission power control TPC command from at least two links, where the TPC command on the at least one link adopts a second power control algorithm.

The second power control algorithm is used for the TPC command on at least one of the links of the UE. The algorithm used on the links of the UE may be the same as that in the first embodiment.

Step S32: determining whether to receive the power reduction in a preset time period in an adjustment period The TPC command, where the preset time period is a fixed transmission time period of the TPC command of the second power control algorithm, and the time length of the preset time period is an integer multiple of one time slot length. If yes, step S33 is performed, otherwise step S34 is performed.

Step S33: Receive a power-down TPC command in a preset time period in an adjustment period, determine that the power adjustment command is a power-down adjustment command, and perform step S40.

In this step, the TPC command received by the UE includes not only the TPC command adopting the second power control algorithm but also the TPC command using other power control algorithms, such as the first, second, third or fourth power described above. Control algorithm.

When the UE determines, the method for determining all the TPC commands received in the preset time period is as described in the second embodiment, and details are not described herein.

Step S34: In the preset time period, the received TPC commands are all the power-up TPC commands, and then it is determined whether there is a power-down TPC command in the TPC command decision result on the link using other power control algorithms when the adjustment period is over. If yes, go to step S35. Otherwise, according to whether the TPC command decision result includes the hold power TPC command, step S36 or step S37 is performed respectively.

In this step, when the TPC commands received in the preset time period are all the power-up TPC commands, the power adjustment command is not directly determined to be the power-up adjustment command, but the other power control algorithm is determined when the adjustment period is over. Whether there is a power reduction TPC command decision result in the TPC command decision result on the link.

Step S35: When the adjustment period is completed, the TPC command decision result on the link using the other power control algorithm has a power reduction TPC command decision result, and the power adjustment command is determined to be a power down adjustment command.

For example, when the adjustment period is completed, the decision result of the TPC command on a link adopting the first power control algorithm is the power reduction, and then the power adjustment command is determined to be the power down adjustment command.

Step S36: When the adjustment period is completed, the TPC command decision result on the link using the other power control algorithm is the power-up TPC command, and the power adjustment command is determined as the power-up adjustment command.

Step S37: When the adjustment period is completed, the TPC command decision result on the link using the other power control algorithm includes at least one power hold TPC command decision result, and then determine the number of the power-up TPC commands in the TPC command on all links. Whether it is greater than the number of power-saving TPC commands, if yes, go to step S38, otherwise go to step S39.

After the adjustment period is over, when there is no power reduction TPC command decision result in the TPC command decision result using other power control algorithms, the power adjustment command is not directly determined as the power up adjustment command, but the TPC command of the other power control algorithm is further determined. Whether there is a power hold TPC command decision result in the judgment result.

When the TPC command decision result on the link using the other power control algorithm includes at least one power hold TPC command decision result, it is determined according to the number of the full link rising power TPC command and the number of the hold power TPC command. The power is still maintained, and the specific method determined may be set according to actual requirements. For example, when the number of power-up TPC commands is greater than twice the number of power-holding TPC commands, the power adjustment command is determined to be a power-up adjustment command. Otherwise, The power adjustment command is determined to maintain the power adjustment command.

In this embodiment, only the number of the power-up TPC commands is greater than the number of the power-up TPC commands is specifically described as an example.

Step S38: The number of the power-up TPC commands in the TPC command on all the links is greater than the number of the power-up TPC commands, and the power adjustment command is determined to be the power-up adjustment command.

Step S39: The number of the power-up TPC commands in the TPC command on all the links is not greater than the number of the power-up TPC commands, and the power adjustment command is determined to be the power-hold command.

If the number of the power-up TPC commands in the TPC command on all the links is greater than the number of the power-up TPC commands, the following formula can be used:

是否成立，Judgment formula

Whether it is established,

If it is established, the UE raises the transmission power, otherwise the UE maintains the transmission power.

or,

是否成立，Judge

Whether it is established,

If it is established, the UE raises the transmission power, otherwise the UE maintains the transmission power.

In the above formula, N is the number of links of the UE, X is the number of links using the second control algorithm, and N-X is the number of links using the first control algorithm.

Step S40: Adjust the transmission power according to the power adjustment command.

In this step, when the power reduction TPC command is received within a preset time period, the power adjustment life is determined. When the power down adjustment command is used, the power down adjustment command may be executed in a preset time slot after the preset time period is completed, and the power is reduced according to the power down adjustment command, for example, ending in a preset time period. The transmit power is adjusted in the next time slot after receiving 512 chips, wherein the result of the adjustment may be maintained until the next power adjustment command is executed; or, the preset time slot after the adjustment period is decreased according to the power. Adjusting the command to reduce the transmit power. For example, adjusting the transmit power at the start position of the next adjustment period after receiving the 512-chip after the end of the adjustment period, wherein the result of the adjustment can be maintained until the next power adjustment command is executed. before.

In addition, the power adjustment command determined after the end of the adjustment period may be executed after a preset period of time after the adjustment period.

In the power adjustment method of the embodiment, when the UE determines that the power adjustment command is the power down adjustment command within the preset time period, the UE may not judge the TPC commands in other time slots, only when all the TPCs in the preset time period are used. When the command is not the power-down command, the power adjustment command is determined according to the TPC command decision result of other power control algorithms. This method further ensures the priority of the power-down adjustment while simplifying the power adjustment method, thereby effectively ensuring that the UE performs the drop. Power commands reduce power consumption during UE communication.

4 is a schematic flowchart of Embodiment 4 of a power adjustment method according to the present invention. The method does not limit the transmission time of the TPC command of the second power control algorithm. Therefore, the TPC command on the link of the UE adopting the second power control algorithm may be randomly. In each slot of the adjustment period, in this manner, the method for power adjustment includes:

Step S41: Receive a transmission power control TPC command from at least two links, where the TPC command on the at least one link adopts a second power control algorithm.

Step S42: Determine whether to receive the power-down TPC command of the second power control algorithm in each time period in an adjustment period, wherein each time period does not overlap, and the total length of each time period is the same as the adjustment period, preferably The length of each time period may be the length of one time slot; once received, step S43 is performed, and each time period in the adjustment period is not received, and step S44 is performed.

Due to the randomness of the TPC command transmission of the second power control algorithm, the UE determines whether the power reduction TPC command of the second power control algorithm is received in each time period in the adjustment period.

Step S43: receiving the power reduction of the second power control algorithm within a certain period of the adjustment period The TPC command determines that the power adjustment command is a power down adjustment command, and performs step S50.

After receiving the power-down TPC command of the second power control algorithm, the UE determines that the power adjustment command is a power-down adjustment command within a certain period of the adjustment period, and does not need to determine the TPC command received after the period.

Step S44: The TPC commands that receive the second power control algorithm in each period of an adjustment period are all the power-up TPC commands, and then, when the adjustment period is over, determine the TPC command decision on the link using other power control algorithms. If there is a power-down TPC command decision result, if yes, step S45 is performed. Otherwise, according to the TPC command decision result, whether there is a power hold TPC command decision result, steps S46 and S47 are respectively performed.

Step S45: When the adjustment period is completed, the TPC command on the link using the other power control algorithm has a power-down TPC command, and the power adjustment command is a power-down adjustment command.

Step S46: When the adjustment period is completed, the TPC command decision result on the link adopting other power control algorithms is a power-up TPC command, and the power adjustment command is determined to be a power-up adjustment command.

Step S47: At the end of the adjustment period, the TPC command decision result on the link using the other power control algorithm includes at least one power hold TPC command decision result, and determine the number of the power-up TPC commands in the TPC command on all links. Whether it is greater than the number of power-preserving TPC commands, if step S48 is performed, otherwise step S49 is performed.

In this embodiment, when the adjustment period is completed, if the power-down TPC command decision result is not found in the TPC command decision result of the other power algorithm, and the TPC command decision result in the other power algorithm has the hold power TPC command decision result, The method for determining whether the power adjustment command is a power-up adjustment command or a power-down adjustment command is determined according to the number of the power-off TPC command determination result and the number of the power-up TPC command determination result, and the specific determination method may be determined as shown in this embodiment. Whether the number of the power-up TPC commands is greater than the number of the power-up TPC commands, and whether the ratio of the number of power-up TPC commands to the number of power-up TPC commands is greater than a set threshold, and if it is greater than, the power adjustment is determined. The command is a power-up adjustment command, otherwise the power adjustment command is determined to be a power-down adjustment command.

Step S48: The number of the power-up TPC commands in the TPC command on all the links is greater than the number of the power-up TPC commands, and the power adjustment command is determined to be the power-up adjustment command.

Step S49: The number of power-up TPC commands in the TPC command on all links is greater than the holding power Rate the number of TPC commands and determine that the power adjustment command is a power hold command.

Step S50: Adjust the transmission power according to the power adjustment command.

In this step, when the power reduction command of the second power control algorithm is received in a certain period of the adjustment period, and the power adjustment command is determined to be the power down adjustment command, the manner in which the power reduction adjustment command is executed may include: The preset time slot after the end of the time period is reduced according to the power down adjustment command, or the transmission power is reduced according to the power down adjustment command in the preset time slot after the adjustment period.

In addition, the power adjustment command determined after the end of the adjustment period may be executed in a preset time slot after the adjustment period.

In the power adjustment method of the embodiment, the UE determines whether to receive the power-down TPC command of the second power control algorithm in each period of the adjustment period, and receives the power-down TPC command of the second power control algorithm in a certain period of time. When the power adjustment command is directly determined as the power down adjustment command, the other TPC commands need not be judged. Only when the received TPC commands of all the second power control algorithms are not the power down TPC commands, other The TPC command decision result of the algorithm determines the power adjustment command. This method further ensures the priority of the power reduction adjustment while simplifying the power adjustment method, effectively ensures that the UE performs the power reduction command, and reduces the power consumption during the UE communication process.

Step S55: The TPC commands using the second power control algorithm are all the power-up TPC commands, and the TPC command decision results on the link using other power control algorithms include at least one power-preserving TPC command decision result to determine all links. Whether the number of the power-up TPC commands in the TPC command is greater than the number of the power-up TPC commands, and if so, step S56 is performed, otherwise step S57 is performed;
