Invention

Problems that Ming is trying to solve

In 001, the above works will be performed in multiple times, but in this case, there were problems described below.

I will explain this topic with reference to. Is

It is a composition that has a set relative to the stem timing, and a composition when the competition matches the stem timing.

In the case of 001, the fixed time of the call and the PC formation time also have a set relative to the system timing. In other words, it is equivalent to the effective processing of the call within the allowable period. Becomes On the other hand, in the case of, since the fixed time of the call and the PC formation time are perfectly matched, it is required that the effective processing time for the allowable time is short, that is, the load is concentrated. Is equivalent to

When the system accepts this situation, it must perform high-speed processing to handle this situation. For example, if it is assumed that the logic is also a signal processor, it is conceivable to use a high-speed processor that can handle the load.

However, it is generally said that a faster processor is more expensive.

Also, as a logical configuration of the above theory, when processing is done by deciding on a unit basis, for example, 2 per 1 ombo, it is possible to keep the permissible interval for a certain call, but not for a certain call. Problem occurs. If the time is not kept, power will be generated and power will be deteriorated.

[0118] In addition, it is configured to be performed by 8 PCs 2, and the modulation, modulation 3 modulation, spread 4 power, and power consumption.

The setting and processing in 6 will be continued.

[0119] That is, the timing for inputting the PC band is such as modulation, spread, power

It is necessary to process it further in time considering the time. This is effectively 9

It means that the PC completion time is even shorter, and it is thought that the problem under load will become more serious.

[0020] The present invention has been made in view of the above circumstances, and an object thereof is to provide a wireless station and a control method thereof, in which power control is mitigated and control is mitigated by a simple method.

To solve the problem

To solve the problem of 002,

Input signal to generate a signal, a modulation to perform a first-order modulation on the generated data, a spread modulation using a signal of, a power determined by the power, and a power to be multiplied by the spread modulation signal. And have.

002 Also, in the above case, when the power and transmission data are timed at the input power (PC) time, the sign of the transmission power value depends on the input power (PC) end. Has the function of reversing.

002, above, the power in the power

The power consumption and the transmission power value in power are determined by call timing, and the control process in the power status and the control process in the power status are defined collectively or in units under the base station. It is a thing.

Regardless of the quality of the received signal, a fixed number of boxes are input as the power and power levels, and a timing report for identifying the type of the input power is generated and output to the power level. Then, the modulated and modulated data is modulated, spread and spread, and the power level corresponding to the received quality measured by power and quality is set based on the timing report, and the spread data is set. The power is fixed to the computer. In the above-mentioned control method, the power and the transmission power value are determined, and the sign of the transmission power value is inverted according to the power and the power consumption.

Of Ming

According to 002, a radio that puts power into the data so that the quality of the signal at the end of the move is constant and adjusts the transmission power based on the power at the end of the move The quality of the signal that is measured, the power status that controls the conditions that determine the power level that is input to the transmission data, and the power level that is input according to the conditions that determine the quality and the power level of the measured reception signal. The power level to be determined, the detection and synchronization of the power level from the received data, the power status to control the conditions for determining the received power for the call, and the power level for the determined power and the conditions to determine the transmitted power. Power to determine the power, the input of the synchronous it's bonder to the encoded data to generate the modulation, the modulation to Key and determined by power The received power, the power multiplied by the spread-tuned signal and the

By setting the power consumption in terms of power, it is possible to delay by the power, modulation, and spread in the power consumption that requires time, and even when the time is required. Load There is an effect that can be.

According to the clarification, in the above, when the power and transmission data are input at the power (PC) time which is input in time, according to the input power (PC), It has a function of inverting the sign of the transmission power value. According to 002, it is a radio control method that puts power into the data so that the quality of the signal at the end of the movement is constant and adjusts the transmission power based on the power in the data after the movement. Therefore, regardless of the quality of the received signal measured by the quality, a certain box is inserted as a power and power channel, and a timing report is generated to identify the box in which the channel is inserted. Output to, modulate and spread the modulated data, spread and spread, set the power level corresponding to the received quality measured in power and quality based on the timing report, and spread it. Since the power is fixed to the data, the power can be set to the power, so that the delay between the modulation, the modulation, and the spread in the power that requires time can be delayed. , The reason why timeliness is required concentrated Even in this case, there is an effect that the load can be distributed.

According to M. 0300, the determination of the power consumption in the power consumption and the determination of the transmission power value in the power consumption are performed by call timing, and the control processing in the power consumption status and the control in the power status are controlled by the base station. In batches or in units

The station and its control method are defined as follows.Therefore, it is the reason for power and power that requires time, and the condition for power and status that does not require time. Can be separated and used with different timings, which has the effect of reducing the amount of time that requires time.

Good for carrying out the invention

003 Explain with reference to the surface in the state of Ming.

As for the wireless station and its control method related to the implementation of Ming, the PC of the power supply is set in advance and the power supply of the power supply is set to 〒. The delay between modulation and spreading can be delayed, and the load can be spread even if the processing is concentrated. In addition, the radio related to the implementation of the invention, the control of the PC and the power that requires the time, and the control of the power and the power that do not require the time. Since they are separated and have different timings, it is possible to reduce the amount of time that requires time.

The details will be described with reference to the radio configuration related to the implementation of Ming. [Fig. 3] is a radio block diagram according to the implementation of Ming.

The radio () related to the implementation of Ming is, as shown in, the reception of the sun under the base station and the reception unit 5 52 53 ... It comprises a unit 6, a power status 7 for controlling the condition for determining the transmission power, and a PC status 8 for controlling the condition for determining the incoming PC band.

, The sun receiver 5 is responsible for Z (C), the sun receiver 52 is responsible for (C), and the sun receiver 53 is responsible for net 2 (C 2).

003 The receiver unit sends the transmission data of 5 and the synchronization data of the encoded data to the PC 5 2 and, for example, the key of PS 6 etc. , 5 is used to determine the spread spectrum, and the value of is determined and the power 5 5 is multiplied by the power determined by the signal and power 5 5 And again, from the received signal

To extract the reception of the call, 5 7 5 7 2 to apply the synchronization wave to the extracted signal, and 5 8 5 8 2 to apply the (S) to the extracted signal. S59 to measure, PC5 to determine the PC from measured S5, PC5 to judge by the PC of the synchronized reception signal, and data to judge by the data of the synchronized reception. 5 2 and judged transmission Is made up of rows 5 3.

Further, C 6 is a site where the addition of is added.

Status 7 is a part that controls the conditions for determining the signal power for a call under wireless communication.

The PC status 8 is a part that controls the conditions for determining the PC input to be placed for the call under the radio.

Next, the operation in will be explained with reference to.

The data obtained in step 5 is input to column 52. In the system 52, the PC of the sync-it-board is input to the data. Itombo and PC hands are entered in the transmission period as in the conventional method. The ytombo is the so-number assigned based on the stem timing, and the kombo that is known at the end is inserted.

In the case of 003 Ming, a fixed boss is inserted with a double, regardless of the S specified for the PC nd entered in MU 52. In addition, the MU 52 generates a PC timing report so that it can identify the bot that has inserted the PC nd and uses it as power. Then, the muted data is modulated by the modulation 53, spread by the spreading 54, and input to the power 56.

At 5 6, power is fixed and PC power is turned on.

004 Here, we will explain the PC-and-power method at a power of 56 using 2. Figure 2 is a power diagram.

In 2, PC 6 determines that the input PC (PC), which is the power of PC 5, is P or OW.

If OW is OW according to the above-mentioned PC report, 004 will output, and if P is w

If so, switch to. 004 6 3 is the constant power value that is the power of 5 5 Is multiplied and the signal is added to the fixed power value.

6 4 multiplies the fixed power value with or with the fixed power value 5 4 and outputs the signal after the power is fixed.

As mentioned above, the PC card that is inserted in the frame 52 is a fixed card. Assuming PS in the first order and assuming 3, the PC ombo will take either () (2) of 3. Figure 3 shows an example of a PC keyboard in QPS mode.

004 Input the PC timing information from the system 52, operate the PC timing and PC handle 6 2 and add the signal to the power constant value by the multiplication 6 3 and perform (constant value) and (constant value). . Assuming that the PC input to be input in 004 is P (3 ()), if the force value of multiplication 6 3 is (constant value), PC become.

On the contrary, when the force value of the multiplication 63 is 10 (constant value), the PC and the multiplication factor of 3 () are maintained.

With 004, it is possible to effectively delay the PC timing compared to the conventional method.

The received signal f is divided by 5 7 5 7 2 according to the current code, synchronized by 5 8 5 8 2 in synchronization, the PC keyboard is judged by PC 5, and the data is data 5 Judged in 2. The data judged in the data 52 is shown in the data 53, and the received data can be obtained.

004 Here, description will be made using 4 to 7 as the means for controlling the transmission power.

4 is a diagram showing the conditions for setting the transmission power, 5 is a diagram showing the power status and power, 6 is a diagram showing the conditions for setting the PC, and 7 is a diagram showing the conditions for setting the PC. FIG. 3 is a diagram showing a PC status PC.

For power transmission status shown in 004 Then, if the result is changed to electric power 55, the electric power 55 is controlled according to the result. 004, when is input to the power status 7, the judgment is made according to the condition corresponding to the condition and judgment column, and the power is judged according to the judgment result as shown in the column. 5 5 controls the state.

005 0 Status 7 judges whether each state is possible or systemable, and as output, as described in 5, the compulsory force increase, power od (), judgment, Select from d control by the PC, 2d control by the PC, and transmission O status to use as the power status.

005 15 5 operates based on the power status.

For example, when d status is specified by the judgment PC, the fixed PC is calculated by the timing and the judgment PC is decided.

Use the value to determine and update the constant value.

As in the above example, as for the part () related to the determination of the power value, for example, as the part that can be processed for the first time after the result of the PC is known, the real time property such as power 5 5 is required. , The part that is not required to be truly timed by knowledge is divided into the process in power status 7.

For PC setting shown in 00536, in PC status 8

Then, if the result is set to PC 5, PC 5 will be controlled according to the result.

005 4 shows the reason for determining the PC, but 7 is W

An example of a case for determining a PC in C is shown.

Based on the power of 6, the PC status 8 judges under the conditions of 6 and establishes the status for each. For each state, determine whether it is possible or not, and the output is as described in 7. Input the inverted output with respect to the output, input the forced P input, input the result of Tag R and R result, and select any one of the statuses as the PC status.

005 PC 5 operates based on the PC status.

For example, when the status of Ta ge R and the result of R is specified, the PC is output at the timing, and the PC is determined and updated by using R and Ta ge R for decision.

As in the case of PC, as in the case of PC, as in the above example, as a part that can be processed for the first time after the result of R in () concerning the setting of PC is known, such as PC 5, It is divided into the reason why timeliness is required and the part of PC status 8 that is the part where knowledge does not really require timeliness.

As described above, the explanation will be given on the power supply and reception power for a plurality of groups by dividing into () which requires truly timeability () and () which does not require truly timeability.

It is also possible to perform batch processing depending on the situation of the processor, for example, by utilizing the fact that the status that the time is not really required and the PC status are known. Therefore, it is possible to uniquely determine the unit and distribute the load. As a result, it is possible to reduce the theoretical load that truly requires timeliness. Is also relieved.

As explained in detail above, the composition and transmission power control procedure has the effect of distributing the load of transmission power management and increasing the effective time for PC generation.

Above, 005, is suitable for a wireless station and its control method that relaxes the control of power by a simple method and also relaxes control.
