Description

[0001] TERMINAL AND CONTROL METHOD THEREOF [0002]

The present invention relates to a terminal and a control method thereof, and more particularly, to a terminal capable of determining whether to operate in a turbo mode when power is supplied through a plurality of power supply units and a control method thereof.

Generally, a wireless communication system is a multiple access system capable of supporting communication with multiple users by sharing available system resources (bandwidth, transmission power, etc.).

Examples of the multiple access system include a CDMA (Code Division Multiple Access) system, a FDMA (Frequency Division Multiple Access) system, a TDMA (Time Division Multiple Access) system, an OFDMA (Orthogonal Frequency Division Multiple Access) system, Carrier Frequency Division Multiple Access (CDMA) systems.

It is necessary to control an uplink transmit power in a wireless communication system. This is to adjust the magnitude of the received signal at the base station to an appropriate level. If the transmission power is too weak in the uplink transmission, the base station can not receive the transmission signal of the terminal. Conversely, if the transmission power is too strong, the transmission signal of the terminal can interfere with the transmission signal of the other terminal and increase the battery consumption of the terminal. By controlling the uplink transmission power and maintaining the size of the received signal at an appropriate level, it is possible to prevent unnecessary power consumption in the terminal and to improve the transmission efficiency by adaptively determining the data rate or the like.

Therefore, it is required to develop various technologies for efficiently controlling uplink transmission power in a wireless communication system.

According to another aspect of the present invention, there is provided a terminal comprising: a body; A first power supply unit provided at one side of the body and supplied with power from another device; A second power supply for selectively receiving power from the another device; And a wireless communication unit for generating a wireless signal from the power supplied through at least one of the first and second power supply units.

According to another aspect of the present invention, there is provided a method of controlling a terminal, the method comprising: determining whether a terminal is in a first state in which power is supplied through a plurality of power supply units; And a first determining step of determining whether the output of the terminal operates in an enhanced turbo mode when the terminal is in the first state.

For clarity of explanation, 3GPP LTE / LTE-A is mainly described, but it is clear that the technical idea of the present invention is not limited thereto.

1 shows a wireless communication system.

The wireless communication system 10 includes at least one base station (BS) 11. Each base station 11 provides a communication service to a specific geographical area (generally called a cell) 15a, 15b, 15c. The cell may again be divided into multiple regions (referred to as sectors). One base station may include more than one cell.

A mobile station (MS) 100 may be fixed or mobile and may be a user equipment (UE), a user terminal (UT), a subscriber station (SS), a wireless device, , A wireless modem, a handheld device, an access terminal (AT), and the like.

The base station 11 generally refers to a fixed station that communicates with the terminal 100 and includes an evolved-NodeB (eNB), a base transceiver system (BTS), an access point, an access network ), And the like.

Hereinafter, downlink (DL) means communication from the base station 11 to the terminal 100, and uplink (UL) means communication from the terminal 100 to the base station 11.

In the downlink, the transmitter may be part of the base station, and the receiver may be part of the terminal. In the uplink, the transmitter may be part of the terminal, and the receiver may be part of the base station.

2 shows a structure of a radio frame in 3GPP LTE.

A radio frame is composed of 10 subframes, and one subframe is composed of two slots. The time taken for one subframe to be transmitted is referred to as a transmission time interval (TTI). For example, the length of one subframe may be 1 ms and the length of one slot may be 0.5 ms.

One slot includes a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time domain and a plurality of resource blocks (RBs) in a frequency domain. The OFDM symbol is used to represent one symbol period because 3GPP LTE uses OFDMA in the downlink and may be referred to as an SC-FDMA symbol or a symbol period according to the multiple access scheme. The RB includes a plurality of consecutive subcarriers in one slot in a resource allocation unit.

The structure of the radio frame shown in FIG. 2 is merely an example, and the number of subframes included in a radio frame, the number of slots included in a subframe, and the number of OFDM symbols included in a slot can be variously changed.

The uplink channel used in 3GPP LTE includes a Physical Random Access Channel (PRACH) for random access, a Physical Uplink Control Channel (PUCCH) for control information transmission, A Physical Uplink Shared Channel (PUSCH), and the like.

According to the PUSCH transmission and configuration method defined by the LTE standard as well as the data transmission, the PUSCH can transmit information in which control information and data are multiplexed or information composed only of control information.

The random access information has importance as information for random access between the base station 11 and the terminal 10. [

And, the control information has importance such as the coverage balance of the uplink and the downlink and the feedback of the downlink.

The details of each of the uplink channels are well known in the art and will not be described in detail.

Hereinafter, a terminal 100 related to the present invention will be described in detail with reference to the drawings. The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role.

4 is a block diagram of a terminal according to an embodiment of the present invention.

The terminal 100 according to an embodiment of the present invention may include a wireless communication unit 110, an interface unit 150, a memory 140, a controller 160, and a power supply unit 170.

The wireless communication unit 110 may include one or more modules that enable wireless communication between the terminal 100 and the wireless communication system or between the terminal 100 and the network in which the terminal 100 is located.

The wireless communication unit 110 may support wireless communication using at least one wireless communication protocol. For example, the wireless communication unit 110 may provide wireless communication by at least one of CDMA, WCDMA, and LTE communication methods.

When the wireless communication unit 110 provides wireless communication using a plurality of different wireless communication protocols, the wireless communication function according to each wireless communication protocol may be implemented as one chip, .

The interface unit 150 serves as a path for communication with all external devices connected to the terminal 100. The interface unit 150 receives data from an external device or receives power from the external device, transfers the data to each component in the terminal 100, or transmits data in the terminal 100 to an external device. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, A video input / output (I / O) port, an earphone port, and the like may be included in the interface unit 150. In the terminal 100 according to the embodiment of the present invention, the interface unit 150 may be implemented together with the power supply unit 170 described below. That is, it means that the power supply unit 170 serves as the interface unit 150 connected to another device (200 of FIG. 11) and can receive power simultaneously.

The memory 140 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory) (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM A disk, and / or an optical disk. The memory 140 may store a program for the operation of the control unit 160 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.).

The controller 160 controls the overall operation of the terminal 100. For example, data communication through the wireless communication unit 110, transmission power control of an uplink channel, and the like.

The power supply unit 170 may receive power from an external power source under the control of the controller 160 and supply power required for operation of the respective components. The apparatus for applying power to the power supply unit 170 may be another device (200 in Fig. 11). The other device (200 in FIG. 11) may be a notebook computer, a desk-tam computer, a mobile terminal, or the like. A method of supplying power to the power supply unit 170 may be a USB (Universal Serial Bus), a DC-JACK, or the like. The power supply unit 170 may include a first power supply unit 120 and a second power supply unit 130.

The first and second power supply units 120 and 130 may selectively supply power to respective portions of the terminal 100 including the wireless communication unit 110 by a control operation of the controller 160 or a user's operation. That is, the first and second power supply units 120 and 130 supply power to the first power supply unit 120 and the second power supply unit 130 may not supply power. At this time, the second power supply unit 130 which does not supply power may be physically and electrically connected to another device (200 of FIG. 11) or may not be connected. For example, even when the second power supply unit 130 is electrically connected to another device (200 of FIG. 11), the control unit 160 controls the power supply through the second power supply unit 130 It can be prevented from being supplied to the terminal 100.

5 is a graph showing the operation of the terminal of Fig.

As shown, the terminal 100 according to an embodiment of the present invention may have a predetermined correlation between the transmission power (Tx Power) required by the wireless communication unit 110 and the required power (mW).

The terminal 100 may be placed in various operating environments. That is, the terminal 100 can operate under a strong electric field environment having a good propagation environment, and in some cases, operate under a weak electric field environment where the propagation environment is unfavorable. Under such various operating environments, a constant transmission power is required in order to allow wireless communication of the terminal 100 to be smoothly maintained. For example, the LTE standard requires that the transmit power be at least 23 dBm under worst-case conditions. In order to output the required transmission power x1 of 23 dBm or more, the terminal 100 must receive the necessary power y1 of about 3600 mW or more through the power supply unit 170. [

According to the USB standard, one USB can supply 2500mW of power. Therefore, one USB may not be able to output the transmission power required by the LTE standard. Therefore, the terminal 100 according to an embodiment of the present invention may receive power through two or more USBs. However, under circumstances where the propagation environment is good, the required transmission power (x1) can also be output even when the power supply below the power supply y1 is supplied to the terminal 100. [ Therefore, it is necessary to maintain the optimized power state by selectively receiving power from the USB.

6 is a circuit diagram of the terminal of Fig.

As shown, the terminal 100 according to an embodiment of the present invention can be selectively supplied with power from another divisor 200.

6A, the first power supply unit P1 provided in the terminal 100 can receive power from the first USB port U1 provided in the other device 200. As shown in FIG. The first power supply unit P1 may be a USB plug, a USB port, a power socket, or the like provided in the terminal 100.

When power is supplied to the first power supply unit P1, a high signal can be input to the modem chip MC in the absence of the auxiliary power input to the transistor provided in the circuit on the terminal 100 side. When a high signal is inputted to the modem chip MC, the first indicator light L1 indicating the normal mode in the indicator light L may be turned on.

The normal mode means that the output of the wireless communication unit 110 of the terminal 100 is in a normal state. In the case where the propagation environment is good, the terminal 100 can generate transmission power that can satisfy the LTE standard even if power is supplied from one USB. In this state, the terminal 100 operates in the normal mode.

The first power supply unit P1 provided in the terminal 100 receives power from the first USB port U1 and the second power supply unit P2 supplies power to the second USB port U1, And power can be supplied from the port U2.

When power is supplied to the terminal 100 through the first and second power supply units P1 and P2, a low signal may be input to the modem chip MC. In this case, a signal indicating a turbo mode 2 indicator light L2 may be turned on.

The turbo mode means that the output of the wireless communication unit 110 of the terminal 100 is stronger than the normal mode. If the propagation environment is poor, the terminal 100 may not be able to generate transmission power that can meet the LTE standard by being powered from one USB. Therefore, power can be supplied from two USBs to generate sufficient transmission power, and the case where the terminal 100 operates in this state is the turbo mode. Specifically, as described above, a case where power of at least about 3600 mW is supplied from two USBs and transmission power of 23 dBm or more is generated may be a turbo mode.

FIG. 7 is a flow chart showing the operation of the terminal of FIG. 4;

As shown in the figure, the terminal 100 according to an embodiment of the present invention may include a step of receiving power (S10).

The power source may be supplied from the first USB port U1 or the second USB port U2 of the other device 200 or may be supplied from the first and second USB ports U1 and U2 as described above. A specific method of receiving power from another device 200 will be described in more detail in the corresponding part.

When power is supplied, step S20 may be performed to determine whether the second power supply unit P2 is connected.

If power is supplied, power can be supplied to the terminal 200 through the first power supply unit P1.

The limit of the power supplied to the first power supply unit P1 is determined by the capacity of the first USB port U1 of the other device 200 corresponding to the first power supply unit P1. According to the USB standard, it is possible to supply 2500mW at 5V, 500mA through one USB.

The first power supply unit P1 can transmit and receive data between the terminal 100 and another device 200 while receiving power from another device 200. [ This may be possible because the first power supply P1 is composed of a USB port or a plug.

The second power supply unit P2 may be selectively connected to the controller 160 or the user. For example, when power of 2500 mW or more is required, the controller 160 receives power from the second power supply P2, and if not, can cut off the power supply from the second power supply P1. This makes it possible to efficiently distribute and use power. The second power supply unit P2 can be used as a path through which power is supplied only without transmitting and receiving data.

If the second power supply P2 is not connected, step S30 of operating in the normal mode may proceed.

If the second power supply unit P2 is not connected, the controller 160 may control the terminal 100 not to request a power supply error that the terminal 100 can provide. For example, if it is necessary to operate under a weak electric field environment, the control unit 160 may transmit a control signal to the other device 200, and the other device 200 may require a power supply Can be displayed. In addition, the controller 160 can inform the user of the situation that additional power connection is required by using a lighting device (not shown) provided outside the terminal 100. In addition, the controller 160 may stop the communication by controlling the wireless communication unit 110 if additional power is required but the power supply is not supplied.

If the second power supply P2 is connected, operation S40 may be performed according to the operation mode.

If the second power supply unit P2 is connected, the control unit 160 can supply the necessary power to the terminal 100. [ Accordingly, the control unit 160 supplies power required by the wireless communication unit 110 to allow the terminal 100 to operate smoothly even in a poor propagation environment. In addition, the control unit 160 may receive the control signal from another device 200 and may cause the terminal 100 to operate in the normal mode or the turbo mode according to the control signal. Hereinafter, a process of operating according to the operation mode will be described in more detail with reference to FIG.

FIG. 8 is a flow chart specifically showing an operation step according to the operation mode of FIG. 7, and FIGS. 9 and 10 are views showing screens for selecting the operation mode of the terminal of FIG.

As shown in these drawings, the step of operating according to the operation mode (S40 in Fig. 7) may include the step S41 of recognizing the connection of the second power supply unit.

When it is recognized that the second power supply unit is connected, step S42 of displaying the operation mode selection window SP may proceed.

The operation mode selection window SP can be displayed on a display (not shown) of another device 200. [ The displayed operation mode selection window SP may include a current power status window PP and a mode selection window MO.

9 (a), the operation mode selection window SP can display the first port status window PP1 and the second port status window PP2 in the power status window PP, The normal mode window (MN) and the turbo mode window (MT) can be displayed in the mode selection window (MO). 9 (a), it is assumed that only the first power supply unit P1 is connected. The user can recognize this state since the first port status window PP1 is displayed differently from the second port status window PP2. In addition, since only the first power supply P1 is physically connected, the controller 160 can not connect the second power supply P2. Therefore, both the normal mode window MN and the turbo mode window MT are inactivated.

The first and second port status windows PP1 and PP2 are all selected in the power status window PP of the operation mode selection window SP as shown in FIG. 9 (b). Accordingly, the user can know that the first and second power supply units P1 and P2 are all connected. 9A, the normal mode window MN and the turbo mode window MT are activated because the first and second power supply units P1 and P2 are connected to each other. However, in order to indicate that the terminal 100 is operating in the normal mode, only the normal mode window MN is selected and displayed.

As shown in Fig. 9C, the turbo mode window MT can also be selected and displayed differently from Fig. 9B. Therefore, the user can intuitively recognize that the terminal 100 is operating in the current turbo mode.

FIG. 9 shows that the first port status window PP1, the second port status window PP2, or the first and second port status windows PP1 and PP2 are selected in the power status window PP. However, it is needless to say that the hatched area may correspond to a part of the first port status window PP1 or a part of the second port status window PP2 so as to correspond to the status of the currently supplied power source. In such a case, the user can intuitively recognize the amount of power currently being supplied.

When the operation mode selection window is displayed, a step S43 for selecting the turbo mode or the normal mode may be performed.

The turbo mode or the normal mode can be switched by the user selecting the normal mode window MN or the turbo mode window MT included in the mode selection window MO. For example, when the user selects the turbo mode window MT in the state shown in FIG. 9B, the current normal mode can be switched to the turbo mode. At the same time, it can be displayed as shown in Fig. 9 (c). 9 (c), the current turbo mode may be switched to the normal mode by the user selecting the turbo mode window MT again. When the user selects the mode, the control unit (not shown) of the other device 200 can transmit the control signal to the control unit 160 of the terminal 100. The control unit 160 of the terminal 100 receiving the control signal from the control unit (not shown) of the other device 200 can switch the normal mode or the turbo mode by controlling the wireless communication unit 110 to correspond to the control signal.

The turbo mode or the normal mode can also be selected by the control unit 160 of the terminal 100. [ For example, if the first and second power supply units P1 and P2 are physically connected, the controller 160 selects a mode so that the optimized power can be used in consideration of the amount of power required by the wireless communication unit 110 . ≪ / RTI >

If the normal mode is selected, step S44 of operating in the normal mode may be performed.

In the course of operating in the normal mode, step S45 may be performed in which it is determined whether or not the set transmission power is requested.

The set transmission power means a transmission power that can be produced by a power supply which can be supplied only by the first power supply unit P1. For example, the set transmit power may be 18dBm, which can be output at 5V, 500mA, 2500mW, which can be supplied by one USB. The controller 160 may monitor the transmission power of the wireless communication unit 110 to determine whether to request 18 dBm of transmission power.

The control unit 160 may enter a step S42 of displaying an operation mode selection window to request the user to connect the second power supply unit P2. If the second power supply unit P2 is already physically connected, the control unit 160 forcibly switches to the turbo mode without displaying the operation mode selection window SP to the user as indicated by a dotted line It is possible. Since the controller 160 can forcibly switch the terminal 100 to the turbo mode, the terminal 100 can be smoothly operated even under a weak electric field.

If the turbo mode is selected, the terminal 100 may proceed to operate in the turbo mode (S46).

In the course of operating in the turbo mode, the control unit 160 may proceed to step S47 of determining whether the connection of the second power supply unit P2 is released.

The turbo mode assumes that the first and second power supply units P1 and P2 are all connected. Accordingly, if a situation occurs such that the user physically disconnects the second power supply unit P2, the terminal 100 can not operate in the turbo mode.

If it is detected that the second power supply P2 is disconnected, step S44 may be performed in which the turbo mode is forcibly transferred to the normal mode and operated in the normal mode.

10A, the first port status window PP1 is displayed in the operation mode selection window SP, and the normal mode window MN and the turbo mode window MT are inactivated . Therefore, it can be seen that only the first power supply unit P1 is connected. In this state, the second power supply unit P2 can be connected.

10B, when the second power supply unit P2 is connected, both the first and second port status windows PP1 and PP2 are displayed and the mode selection window MO is activated have. In addition, a mode selection pop-up window (AP) for selecting the user to switch to the turbo mode may be displayed.

10C, when the user selects the turbo mode switching from the mode selection popup window AP, the terminal 100 is switched to the turbo mode and simultaneously the turbo mode window MT is selected .

10 (d), if the user does not select the turbo mode switching from the mode selection popup window AP, the terminal 100 is switched to the normal mode and at the same time the normal mode window MN is selected as being selected .
