As one of the mainstream technologies of the third-generation mobile communication system, WCDMA (Wideband Code Division Multiple Access) was applied in the early version of UMTS, and HSDPA (High Speed Downlink Packet Access) was introduced in later versions. High Speed Downlink Packet Access) technology is used to improve the downlink data transmission rate, and HSUPA (High Speed Uplink Packet Access, High Speed Uplink Packet Access) technology is used to improve the uplink data transmission rate and reduce 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 keep the received signal with stable reception quality, a power control method is adopted. In the power control method, in order to realize the power control of the uplink channel, the TPC (Transmission Power Control, transmission power control) command is used to control the uplink transmit power of the UE, wherein the TPC command is transmitted on the downlink channel, and when the UE receives the When the TPC command is used, the TPC command is parsed, and based on the power control algorithm adopted by the TPC command, it is instructed to increase the uplink transmission power or reduce the uplink transmission power.

Different power control algorithms may be used for TPC commands in different wireless links. For example, the power control algorithms used on wireless links may include:

The first power control algorithm: receive TPC commands in each time slot of a cycle, perform hard judgment on the TPC commands, and determine the power control result according to the hard judgment results of multiple TPC commands in the cycle.

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

The third power control algorithm: Receive TPC commands in each time slot of a cycle, wherein the TPC commands in the same cycle are all the same, and combine the TPC commands received in the cycle to determine the power control result.

For a UE, when only one radio link is established, power control can be performed directly according to the power control algorithm adopted by the TPC command. When a UE establishes multiple wireless links, especially when at least one wireless link adopts the second power control algorithm, because in the second power control algorithm, power adjustment will be performed after receiving the TPC command, which may cause There is a problem that the power adjustment is too frequent.

Detailed ways

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

Power control is divided into inner loop power control and outer loop power control. Among them, the inner loop power control measures the receiving quality of the channel, such as obtaining the receiving SIR (Signal to Interference Rate, signal to interference ratio)/SNR (Signal to Noise Rate, signal to interference ratio) of the channel. Noise ratio) / SINR (Signal to Interference and Noise Rate, Signal to Interference and Noise Ratio), etc., and compare the measured channel receiving quality with the set target value, generate TPC commands according to the comparison results, and indicate through the TPC commands " Increase the transmit power" or "decrease the 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/symbol error rate of the channel, so that the block error rate/bit error rate/symbol error rate of the channel reaches the desired value.

The channel used by the UE to send data to the base station is called the uplink channel, and the channel used by the UE to receive the data sent by the base station is called the downlink channel. According to different power control channels, the above-mentioned inner loop power control can be further divided into uplink inner loop power control and downlink inner loop power control, wherein the inner loop power control performed on the uplink channel is called uplink inner loop power control.

The TPC command used in the uplink inner loop power control is called the uplink TPC, which is generated according to the quality measurement of the uplink channel and transmitted on the downlink channel to instruct the UE to "increase the uplink transmit power" or "reduce the uplink transmit power". ” or “Maintain uplink transmit power”.

The process of uplink inner loop power control generally includes: the base station measures the reception quality of the uplink DPCCH (Dedicated Physical Control Channel, dedicated physical control channel), compares the measured value with the set target value, and generates an uplink TPC command. The uplink TPC command is sent through the downlink DPCCH or the downlink F-DPCH (Fractional Dedicated Physical Channel, Fractal Dedicated Physical Channel), and instructs the UE to increase or decrease the transmission power of the uplink DPCCH.

The uplink DPCCH includes parts such as the pilot frequency domain and the TPC domain. The pilot frequency in the pilot frequency domain is used for uplink channel estimation and measurement, and the TPC command in the TPC domain is the downlink TPC. The downlink DPCCH includes parts such as the pilot frequency domain and the TPC domain. The pilot frequency in the pilot frequency domain is used for downlink channel estimation and measurement, and the TPC in the TPC domain is the 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 fast power control algorithms and slow power control algorithms, among which 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 makes a hard decision in each time slot. In a period (such as a time of M time slots), if the hard judgment results of the TPC commands received by the UE are the same, the judgment results of the uplink TPC commands will take effect. If the judgment result of the TPC command is to increase the power, then increase the transmit power of the UE, and for example, if the judgment result of the TPC command received by the UE in one adjustment period is to decrease the power, then reduce the transmit power of the UE; within one cycle , if the hard judgment results of multiple TPC commands received by the UE are different, keep the DPCCH transmit power unchanged.

The second power control algorithm: the base station sends an uplink TPC command in one cycle (such as the time of M time slots), that is, only sends the uplink TPC command in one time slot in a cycle, and does not send TPC commands in other time slots. After the UE receives the uplink TPC, it makes a hard decision, and adjusts the power according to the result of the hard decision, where the adjustment time can be a preset time after the end of the time slot in which the TPC is received, or it can be pre-determined after the end of the current cycle. Execute again within the set time. In this manner, the UE adjusts the uplink DPCCH transmit power once every M time slots.

The third power control algorithm: the base station sends TPC commands in each time slot of a cycle, and the TPC commands in the same cycle are all the same. The UE combines the TPC commands received in a cycle and makes a hard judgment. Adjust the transmit power according to the result of the hard decision.

The above-mentioned inner loop power control algorithms are all for a single wireless link. When the UE is within the coverage of multiple cells, it may establish multiple wireless links with multiple cells at the same time. For example, during the soft handover process of the UE, At the same time, it maintains a communication link with both the original cell and the new cell, and only after the UE establishes stable communication in the new cell, does it disconnect from the original cell.

When the UE establishes multiple radio links at the same time, the UE receives TPC commands sent on multiple links in one cycle. If the UE performs power adjustment according to the TPC commands on each link, the following situations may occur: (1 ) The power adjustment results generated by multiple links are different. If there are TPC commands for increasing power and reducing power at the same time, the UE will have power adjustment contradictions; (2) The power adjustment time of the TPC commands used by each link is different. The TPC of the second power control algorithm can perform power adjustment after receiving the TPC command, while the TPC commands of the first and third power control algorithms are adjusted at least at the end of the current cycle. It may be necessary to perform multiple power adjustments, especially when the TPC commands of multiple links use the second power control algorithm, because the TPC commands of the second power control algorithm As a result, the UE frequently adjusts the power, which affects the normal communication of the UE.

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

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

Considering that the first power control algorithm and the third power control algorithm both determine the power adjustment result in the last time slot of a cycle, and perform power adjustment within a preset time after the end of the current cycle, therefore, when each chain of UE When the TPC commands on the road all use the first power control algorithm, the third power control algorithm, or both 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, specifically:

(1) In the last time slot of a cycle, the UE makes a hard judgment on the TPC commands on each link according to the algorithm adopted by the TPC commands on each link, and obtains the intermediate quantity TPC_temp of the N uplink TPC commands. , and then the N TPC_temps are processed as follows:

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

b. When the number of power-up TPC commands in the _N TPC_temps is greater than the number of power-hold TPC commands, it is determined as power-up, otherwise, it is determined as power-hold. The specific calculation can be calculated using the following formula:

时，Among them, when

hour,

Determined as power up, otherwise determined as power down.

When the UE is in the soft handover area, the effective time of the uplink TPC commands of the first power control algorithm and the third power control algorithm is after the last time slot of the current cycle. Therefore, when the UE is in the soft handover area, regardless of the configuration of the first power control algorithm Whether the algorithm is the third power control algorithm or the third power control algorithm, the UE can process it in the above-mentioned manner.

However, when the TPC command of at least one link of the UE adopts the second power control algorithm, because the TPC command of the second power control algorithm can take effect in the time slot after receiving the TPC command, there is no need to wait until At the end of the current cycle, it can be seen that the effective time of the TPC command of the second power control algorithm is different from that of the first power control algorithm and the third power control algorithm. When the second power control algorithm is used, the UE can no longer process the TPC commands on each link according to the above method. Since the TPC command using the second power control algorithm may exist in each time slot of the current cycle, the UE may need to adjust the transmit power frequently in multiple time slots, which not only increases the power consumption of the UE, but may also affect the power consumption of the UE. normal communication services.

An embodiment of the present invention proposes a power adjustment method. When the second power control algorithm is adopted for the TPC commands on at least one link of each link of the UE, the UE selects and processes the TPC commands on each link. The UE performs power adjustment at most once in a period, which solves the problem that the UE may need to adjust the transmit power frequently when each link includes a TPC command using the second power control algorithm.

FIG. 1 is a schematic flowchart of Embodiment 1 of a power adjustment method according to the present invention. The execution body of the method is UE, and the main processing steps include:

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

The UE receives TPC commands from each link, and the TPC command on at least one link adopts the second power control algorithm, which can be divided into the following situations:

(1) Algorithm 2+Algorithm 2: the second power control algorithm adopted 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 the fourth power control algorithm. The fourth power control algorithm here can be a fast power control algorithm. For example, the base station sends an uplink TPC command in each time slot, and the UE receives the TPC command and sends it in each time slot. A hard decision is made in the time slot, and the UE adjusts the transmit power according to the result of the hard decision in each time slot.

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

No matter what combination of (1), (2), (3), (4) and (5) in step S11 is used for the TPC commands on each link of the UE, the UE will The TPC commands on the links are screened to determine the power adjustment command corresponding to the current adjustment period.

The manner in which the UE selects and processes the TPC commands on each link in an adjustment period may be determined according to actual requirements. For example, it may determine whether a power reduction TPC command is received within an adjustment period. Then, the power adjustment command may be determined as the power down adjustment command without considering other TPC commands.

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

The UE adjusts the transmit power according to the determined power adjustment command. The specific execution time can be determined by the UE according to the time slot where the power adjustment command is located. For example, it is executed in the next time slot where the power adjustment command is determined. , or in a set time slot after the current adjustment period ends.

In this embodiment, when the TPC commands on each link received by the UE include the TPC command of the second control algorithm, the UE selects and processes the TPC commands on each link in one adjustment period, and determines a power adjustment corresponding to one adjustment period command, the power is adjusted at most once in one adjustment period, which solves the problem that the power is adjusted too frequently when the TPC commands on each link of the UE include the TPC commands of the second control algorithm.

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

In this embodiment, the RNC (Radio Network Controller, radio network controller) presets the sending time of the TPC command of the second power control algorithm on each link of the UE, so that the UE can receive the TPC command within the preset time period of the adjustment period. All TPC commands using the second power control algorithm. The UE performs screening processing on the TPC commands on each link according to the TPC commands of the second power control algorithm received within the preset time period and in combination with the TPC commands of other algorithms, wherein the TPC commands of other algorithms include but are not limited to For the above-mentioned first, second, third and fourth power control algorithms, the specific processing steps of this embodiment will be described in detail below, including:

Step S21: Receive TPC commands from at least two links, wherein the TPC commands on at least one link use the second power control algorithm.

Among the links of the UE, the TPC command on at least one link adopts the second power control algorithm, and the algorithm adopted on each link of the UE may be the same as that in the first embodiment, and this step will not be repeated.

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

The RNC presets a time period for sending TPC commands of each second power control algorithm. The UE predetermines the time period for sending the TPC command of the second power control algorithm through the configuration information of each link, and receives each TPC command using the second power control algorithm in the preset time period. Wherein, the UE also receives the TPC command using other power control algorithms at the same time as the TPC command of the second power control algorithm.

Specifically, the preset time period may be the length of one time slot, or may be the length of multiple (eg, two, three) time slots, which will not be described one by one here.

The UE determines from the received TPC command whether it has received the reduced power TPC command, and the determination method may include:

(1) After the preset time period expires, the UE determines whether each TPC command received from the preset time period is a power reduction TPC command one by one.

(2) Each time the UE receives a TPC command within the preset time period, it judges whether it is a reduced power TPC command once.

(3) In the judgment method of (1) or (2) above, the UE firstly judges whether the TPC command of the second power control algorithm is a power-down TPC command, and if the TPC commands of the second power control algorithm are both power-up, then This determination is made for TPC commands that employ other power control algorithms.

Step S23: During a preset time period in an adjustment period, a power reduction TPC command is received, and it is determined that the power adjustment command is a power reduction adjustment command.

Step S24: within a preset time period, the received TPC commands are all power-up TPC commands, and it is determined that the power adjustment command is a power-up adjustment command;

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

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

Specifically, when the UE adjusts the transmit power, the adjustment time can be determined according to actual needs, for example, the power adjustment time can be determined by taking the preset time period as a reference. Specifically, it can be preset after the preset time period ends. Time slot, the transmission power is adjusted according to the power adjustment command, for example, the transmission power is adjusted in the next time slot after receiving 512 chips after the preset time period expires, and the result of the adjustment can be maintained until the next time slot. Before the secondary power adjustment command is executed.

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

In this embodiment, each TPC command that adopts the second power control algorithm is received within a preset time period, and all TPC commands received within the preset time period are used to determine the power adjustment command, and there is no need for other commands in the current cycle. The TPC command in the time slot is processed, and the implementation method is simple and convenient, and the power adjustment is performed at most once in one adjustment period, which can effectively solve 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. The problem.

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

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

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

Among the links of the UE, the TPC command on at least one link adopts the second power control algorithm, and the algorithm adopted on each link of the UE may be the same as that in the first embodiment, and this step will not be repeated.

Step S32: in a preset time period in an adjustment period, determine whether a power reduction TPC command is received, wherein the preset time period is the fixed transmission time period of the TPC command of the second power control algorithm, and the time of the preset time period The length is an integer multiple of the length of a time slot, if yes, go to step S33, otherwise go to step S34.

Step S33: In a preset time period in an adjustment period, the power reduction TPC command is received, the power adjustment command is determined to be a power reduction adjustment command, and step S40 is executed.

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

When the UE judges, it judges all the TPC commands received within the preset time period, and the judgment method is as described in the second embodiment, and will not be repeated here.

Step S34: within the preset time period, the received TPC commands are all power-up TPC commands, then determine whether there is a power-down TPC command in the TPC command judgment result on the link using other power control algorithms when the adjustment period ends If the judgment result is yes, step S35 is executed; otherwise, according to whether the TPC command judgment result includes a TPC command for maintaining power, step S36 or step S37 is executed respectively.

In this step, when the TPC commands received in the preset time period are all power-up TPC commands, it is not directly determined that the power adjustment command is a power-up adjustment command, but at the end of the adjustment period, it is determined to use other power control algorithms Whether there is a power reduction TPC command judgment result in the TPC command judgment result on the link.

Step S35: When the adjustment period ends, the TPC command judgment results on the links using other power control algorithms include power reduction TPC command judgment results, and the power adjustment command is determined to be a power reduction adjustment command.

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

Step S36: When the adjustment period ends, the TPC command judgment results on the links using other power control algorithms are all power-up TPC commands, and it is determined that the power adjustment command is a power-up adjustment command.

Step S37: When the adjustment period ends, the TPC command judgment results on the links using other power control algorithms include at least one power maintenance TPC command judgment result, then determine the number of power-up TPC commands in the TPC commands on all links. Whether it is greater than the number of TPC commands to maintain power, if yes, go to step S38, otherwise go to step S39.

When the adjustment period ends, when there is no down-power TPC command determination result in the TPC command determination results using other power control algorithms, the power adjustment command is not directly determined as the power-up adjustment command, but the TPC commands of other power control algorithms are further determined. Whether there is a power hold TPC command decision result in the decision result.

When the TPC command judgment results on the link using other power control algorithms include at least one power maintaining TPC command judgment result, it is determined according to the number of the whole link rising power TPC commands and the number of maintaining power TPC commands whether the Power or maintain power, the specific method of determination can be set according to actual needs. For example, when the number of power-up TPC commands is greater than twice the number of maintain power TPC commands, the power adjustment command is determined as the power-up adjustment command, otherwise It is determined that the power adjustment command is a hold power adjustment command.

In this embodiment, specific description is given by taking whether the number of power-up TPC commands is greater than the number of hold-power TPC commands as an example.

Step S38: Among the TPC commands on all links, the number of power-up TPC commands is greater than the number of power-hold TPC commands, and it is determined that the power adjustment command is a power rise adjustment command.

Step S39: Among the TPC commands on all links, the number of power-up TPC commands is not greater than the number of power-maintaining TPC commands, and the power adjustment command is determined to be a power maintenance command.

When specifically determining whether the number of power-up TPC commands in the TPC commands on all links is greater than the number of hold-power TPC commands, the following formula can be used to calculate:

是否成立，Judgment formula

is it established,

If so, the UE increases the transmit power, otherwise the UE keeps the transmit power.

or,

是否成立，judge

is it established,

If so, the UE increases the transmit power, otherwise the UE keeps the transmit 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 transmit power according to the power adjustment command.

In this step, when the power reduction TPC command is received within a preset time period, and it is determined that the power adjustment command is a power reduction adjustment command, the manner in which the power reduction adjustment command is executed may include: a preset time period after the preset time period expires. In the time slot, the transmission power is reduced according to the power reduction adjustment command. For example, the transmission power is adjusted in the next time slot after receiving 512 chips after the preset time period expires, and the adjustment result can be maintained until the next time. Before the power adjustment command is executed; or, in a preset time slot after the adjustment period, reduce the transmit power according to the power reduction adjustment command, for example, after the end of the adjustment period, after receiving 512 chips at the beginning of the next adjustment period The position adjusts the transmit power, and the result of the adjustment can be maintained until the next power adjustment command is executed.

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

In the power adjustment method of this embodiment, when the UE determines that the power adjustment command is a power down adjustment command within a preset time period, it can no longer judge the TPC commands in other time slots, and only when all TPC commands in the preset time period When none of the commands are power reduction commands, the power adjustment command is determined according to the judgment result of the TPC command using other power control algorithms. This method simplifies the power adjustment method and further ensures the priority of power reduction adjustment, effectively ensuring that the UE performs the power reduction adjustment. Power command to reduce power consumption during UE communication.

Step S43: Receive the power reduction TPC command of the second power control algorithm within a certain time period of the adjustment period, determine that the power adjustment command is a power reduction adjustment command, and execute step S50.

Whether it is greater than the number of the holding power TPC commands, if it is, go to step S48, otherwise go to step S49.

In this embodiment, at the end of the adjustment period, if there is no down-power TPC command judgment result in the TPC command judgment results of other power algorithms, and there is a power-holding TPC command judgment result in the TPC command judgment results of other power algorithms, Determine whether the power adjustment command is a power-up adjustment command or a power-down adjustment command according to the number of judgment results of the power-maintaining TPC command and the number of judgment results of the power-up TPC command. The specific determination method can be as shown in this embodiment. Whether the number of power-up TPC commands is greater than the number of hold-power TPC commands, in addition to whether the ratio of the power-up TPC commands to the number of hold-power TPC commands is greater than the set threshold, if it is greater, then determine the power adjustment The command is a power-up adjustment command, otherwise it is determined that the power adjustment command is a power-down adjustment command.

Step S48: Among the TPC commands on all the links, the number of power-up TPC commands is greater than the number of power-hold TPC commands, and it is determined that the power adjustment command is a power rise adjustment command.

Step S49: Among the TPC commands on all links, the number of power-up TPC commands is greater than the number of power-hold TPC commands, and the power adjustment command is determined to be a power maintenance command.

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

In this step, when the power reduction TPC command of the second power control algorithm is received within a certain time period of the adjustment period, and it is determined that the power adjustment command is a power reduction adjustment command, the manner of executing the power reduction adjustment command may include: In the preset time slot after the end of the time period, the transmission power is reduced according to the power reduction adjustment command; or, in the preset time slot after the adjustment period, the transmission power is reduced according to the power reduction adjustment command.

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

In the power adjustment method of this embodiment, the UE determines whether to receive the power reduction TPC command of the second power control algorithm in each time period of the adjustment period, and when receiving the power reduction TPC command of the second power control algorithm within a certain period of time When the power adjustment command is directly determined to be a power reduction adjustment command, it is not necessary to perform judgment processing on other TPC commands. The decision result of the TPC command of the algorithm determines the power adjustment command. This method simplifies the power adjustment method and further ensures the priority of power reduction adjustment, effectively ensuring that the UE executes the power reduction command and reducing the power consumption during the UE communication process.
