Description

TECHNICAL FIELD [0001] The present invention relates to a method of improving communication success rate and a method of optimizing battery consumption using wireless signal classification code refinement,

The present invention is applicable to a case where a signal transmitted from the radio equipment # 1 is not received by the radio equipment # 2 in the case of transmitting a code to be transmitted and received when a signal is transmitted from the radio equipment # 1 station to the radio equipment # 2 station, 2, the wireless device # 1 can not receive a response signal and controls the transmission power or the sampling rate to improve the communication success rate while optimizing the battery power consumption.

     A conventional technique related to the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2014-0051717 (published on April 25, 2014). 1 is a flowchart illustrating a method of providing battery consumption information for the conventional mobile terminal and its application. 1, the conventional method of providing battery consumption information for a mobile terminal and its application is a method in which when a user downloads (installs) a specific application and then executes (when an execution command is input) And generates an 'application HW Device List' (S10). The generated device list is stored in the memory 60 (S10, S11). On the other hand, when the user uses a specific application, the controller 180 monitors a usage pattern and stores the pattern in a history file format (S12). According to the monitoring operation, the controller 180 recognizes how the user uses the application on average and can calculate how much consumption current is generated on average at the time of executing the application (S13). In addition, the mobile terminal stores information on the consumption current of the main HW device in the form of a DB in the memory 160. Accordingly, the control unit 180 calculates the consumed current for each HW Device List using the application usage pattern information of the monitored user and the DB information about the consumed current of the main HW device stored in the memory 160, The average consumption current (average consumption) expected at the time of use is calculated (S13). Further, the controller 180 calculates an expected calorific value based on the calculated average consumed current. The battery consumption amount of the application is corrected by the calculated average consumption current (average consumption amount) and is displayed together with the heating amount, and the length of the display bar 51 or the size of the rich image 52 is readjusted by the battery consumption amount correction . Then, the controller 180 determines whether or not the usage time (operation occupancy rate information) of each HW device in the entire application usage time, that is, the average pattern in which the user uses the Tango application, based on the last 10 usage logs using the Tango application Information. At this time, the number of recent use can be set by the user. For example, assume that the average pattern information of the HW device is 10% of the main chipset (CPU), 40% display, 5% touch, 30% camera, 5% audio and 10% RF. Accordingly, the controller 180 calculates the average consumption current (for example, 1500mma) expected by the user when using the Tango application by referring to the usage pattern information of the Tango application and the consumed current DB information of the previously stored major HW device. The control unit 180 recognizes the battery voltage state of the terminal through the battery fuel gauge value. When the user executes a specific application and the average consumption current is calculated as described above, the controller 180 refers to the current battery voltage level and the average consumption current value of the calculated application, T1) (S14). At this time, the control unit 180 can know the average usage time (T2) of the application for the last 10 times by the user through the information of 'History File of application'. Accordingly, the controller 180 compares the available time (T1) of the current application with the average usage time (T2) of the most recent application, and uses the current usage time for the current battery level The application is executed (S17). Otherwise, a pop-up message is popped up as UI 55 for determining whether the application is executed together with the application battery consumption information 54, (S18) whether to continue executing the message or to re-execute the message. For example, the application battery consumption information 54 is displayed as an average battery consumption amount (1500mma), a usable time (T1: 30 minutes) and a recent average usage time (T2: 25 minutes) The control unit 180 checks whether a new application is executed for multitasking (S19). If a new application is executed, the controller 180 checks whether a new application is executed after the step S11 (S20). In this manner, the user can perform at least one application and perform multitasking through the above operation.

The conventional technology described above can provide information on the consumed power by estimating battery consumption power, but fails to provide a method of successfully performing communication and optimizing battery consumption. Accordingly, an object of the present invention is to provide a wireless communication device and a wireless communication method, which can distinguish between transmission and reception codes when data is transmitted between two wireless devices, determine communication failure at each step, adjust a transmission output, adjust a sampling rate, And to provide a method for optimizing battery consumption.

A method for improving the communication success rate and optimizing the battery consumption using the radio signal classifying code refinement according to the present invention has the steps of initializing a classifying code and then transmitting a radio signal code of an event transmitted at the time of communication between the radio transmitter and the radio receiver, Determining whether the wireless signal transmitted from the wireless transmitter is received by the wireless receiver based on the message number and the communication number, and transmitting the event again, wherein the message number and the communication number are set to '1' If the radio receiver receives a radio signal from the radio receiver based on the message number and the communication number and it is determined that the radio transmitter has not received the ACK transmitted by the radio receiver, the sampling rate of the radio transmitter is increased &Lt; RTI ID = 0.0 &gt; And transmitting the message number and the communication number in increments of '1' to the wireless receiver. Specifically, the method for improving the communication success rate and optimizing the battery consumption through the detailed specification of the wireless signal classification code according to the present invention includes setting a message number (M / N) and a communication number (C / N) 1, generating an M / N in the signal discrimination code of the event by 1 at each transmission and generating C / N by 1 at each transmission, generating an event at the wireless device # 2, determining whether an ACK is received from the wireless device # 1, determining whether an ACK of a previous event has been received when an ACK is received from the wireless device # 1, Determining whether C / N <self C / N -? Of the ACK apparatus when ACK is not received; determining whether transmission power (P)? Transmission Output Saturation area (P1dB) Increasing P if P? P1dB; and increasing? =? + 1 when C / N <self C / N -? Of the ACK apparatus is not greater than P? And increasing S when S &gt; Smax is not satisfied.

The improvement of the communication success rate and the optimization of the battery consumption through the detailed specification of the wireless signal discrimination code according to the present invention as described above is based on the fact that communication success and failure are repeated in a state in which communication between the wireless device # 1 and the wireless device # The transmission output can be increased or the sampling rate can be adjusted to improve the communication success and the reception sensitivity. Further, another effect of the present invention is to precisely identify the problem in a certain path in the communication between wireless devices and to adjust the transmission output and the sampling rate according to a problem, thereby minimizing battery consumption and maximizing communication reliability It is. Another advantage of the present invention is that the communication reliability can be improved only by the wireless device # 1 regardless of the wireless device # 2 when the communication between the wireless device # 1 and the wireless device # 2 is unstable.

Therefore, if the transmission power is reduced in order to reduce the battery current consumption, the communication reliability may be degraded.

In this case, N = 01 and C / N = 01 assigned to M / N = 01 and C / N = 01 of # 1 and to ACK transmitted from radio device # 2 to radio device # N = 02 and C / N = 02 of the wireless device # 1 and the wireless device # 1 receives the wireless device # 1 from the wireless device # 2 when the event is transmitted again by increasing the reception sensitivity by increasing the sampling rate M / N = 02 and C / N = 02 of ACK.
