The following detailed description of the invention refers to the accompanying drawings, which illustrate, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with an embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.
Various procedures for forming a wireless network between user equipments (for example, a pairing procedure between user equipments) have been performed for transmitting and receiving data between existing user equipments (for example, a smart device or an electronic device capable of wireless communication) . Therefore, it takes a lot of time to form a wireless network between user devices, and users unfamiliar with the device can not easily utilize the data transmission function between the user devices using the user device. Although the necessity of data transmission between user devices in close proximity due to popularization and normalization of user devices such as smart devices is increasing, the data transmission methods between existing user devices do not satisfy users' requirements due to the above problems.
In order to solve this, a case for a mobile terminal according to an embodiment of the present invention discloses a method of performing data transmission between user devices in a simple and intuitive manner (for example, a plug & play method) . Hereinafter, the user apparatus can instruct a smart device or an electronic device (for example, a smart phone, a smart pad, a tablet PC, a notebook PC, a desktop PC, etc.) capable of transmitting and receiving data in a D2D (Device to Device) .

2 is a diagram illustrating a hierarchical structure of a case for a mobile terminal according to an embodiment of the present invention.
Hereinafter, a hierarchical structure of a legacy user device for performing communication between existing user devices and a hierarchical structure of a user device for performing communication between user devices according to an embodiment of the present invention will be described with reference to FIG. 1 and FIG. I will explain.
First, a hierarchical structure of a legacy user equipment operating based on a WLAN protocol will be described with reference to FIG.
A legacy user apparatus that performs communication between existing user apparatuses transmits a large amount of data (e.g., image data) at a data rate of 3Gbps (Giga bit per sec) or higher as shown in FIG. 1, A wireless local area network (WLAN) protocol can be used to transmit data between the base station and the base station.
Here, the WLAN protocol can be used for communication between an access point (AP) and a plurality of STAs (Stations) within a relatively wide coverage (for example, 250 m). In the WLAN protocol, complex and power-consuming MAC (Medium Access Control) layers and PHY (Physical) layers are defined.
For example, in the PHY layer for communication in the 5GHz band of WiGig, transmission or reception of data through a plurality of antennas can be defined based on MIMO (Multiple Input Multiple Output) technology.
Since the PHY layer for WiGig communication in the 60 GHz band uses the beam forming technique, the hierarchical structure can be very complicated.
Therefore, the size of the communication module in the user equipment becomes large and power consumption may be large.
In addition, in a conventional legacy user apparatus, a different protocol adaptation layer (PAL) may be used depending on the type of input data.
Here, the PAL can serve as an intermediate layer for data transmission between layers.
For example, data transmitted based on IP (Internet Protocol) is used for Wi-Fi as a PAL and WiGig Display Extension (WDE) for data transmitted based on a display port / HDMI (high definition multimedia interface) And WiGig Bus Extension (WBE) / WiGig Serial Extension (WSE) may be used as PAL for data transmitted based on Peripheral Component Interconnect Express (PCIe) / universal serial bus (USB).
The layer implemented in the legacy user equipment based on the WLAN protocol is implemented not only for high-speed data transmission between one-to-one devices in proximity, but also for communication between a wide range of devices and external network connection.

On the other hand, a single channel video signal, a multi-channel video signal, or a bidirectional data signal in which a clock signal is not mixed can be directly transmitted to a user apparatus performing high speed wire serial data transmission through radio.
Therefore, no separate synthesis procedure is required at the receiving end. Examples of a single channel video signal, a multi-channel video signal, or a bidirectional data signal in which such a clock signal is not mixed include a MyDP-based signal, a Display Port-based signal, an HDMI-based signal, a USB 3.x- .

According to an embodiment of the present invention, the RF unit included in the radio transmission / reception RF unit may perform only the role of the Tx RF unit or only the Rx RF unit according to the data format of the high speed stream serial data.
Also, depending on the data format of the high-speed wire serial data, the Tx RF unit and the Rx RF add unit may be configured as a pair in the data signal radio transmission / reception RF unit, and the number of the Tx RF unit and the Rx RF unit may be changed.
For example, when the case for the mobile terminal supports both the MHL / MyDP / Display Port / HDMI / USB3.x signals, the plurality of RF units included in the wireless transmitting / receiving RF unit for transmitting the high- And Rx RF units, and a plurality of RF units included in a radio transmission / reception RF unit for receiving high-speed wire serial data can operate with four RX RF units and one TX RF unit.

As another example, when the case for a mobile terminal only supports Display Port / HDMI, a plurality of RF units included in a radio transmission / reception RF unit for transmitting high-speed wired serial data operates with four Tx RF units and receives high-speed wired serial data A plurality of RF units included in the RF transmitting / receiving RF unit can operate with four Rx RF units.
As another example, when the case for the mobile terminal only supports USB 3.0, a plurality of RF units included in a radio transmission / reception RF unit for transmitting high-speed wire serial data operates with one Tx RF unit and one Rx RF unit, A plurality of RF units included in a radio transmission / reception RF unit for receiving serial data can operate with one Tx RF unit and one Rx RF.
That is, a plurality of RF units included in a radio transmission / reception RF unit implemented in a case for a mobile terminal may have a combination of at least one Tx RF unit and / or a combination of at least one Rx RF unit according to a data format of high- Lt; RTI ID = 0.0 > and / or < / RTI > receive data over the wireless medium.
The RF transmitting and receiving RF unit can process all input signals including a serial data signal, a clock signal, and an auxiliary signal. The serial data signal, the clock signal, and the auxiliary signal can be combined according to the type.
Referring to FIG. 4 (b), a plurality of RF units included in the RF transmitting / receiving RF unit may operate as a Tx RF unit for transmitting a control signal and an Rx RF unit for receiving a control signal.
Speed wireless control signal transmission is performed through the first frequency band (mmWave and Tera Hertz band) or a low-speed wireless control signal transmission is performed through the second frequency band (band below 6GHz) according to the speed of the control signal to be transmitted .
Also, as described above, the radio transmission / reception RF unit for only transmitting the control signal may not be separately implemented in the mobile terminal case.

Incidentally, the first user device may be a smart device such as a tablet PC, as well as a mobile terminal such as the smart phone described above, and the second user device may be a display device (TV, monitor, beam projector) , A camera, a camcorder, a printer, and the like.
If the first user device is a tablet PC, the first wireless transmission / reception processing device may be implemented as a case for a tablet PC.
In addition, when the user device is a smart phone, a tablet PC, or the like, a wired video signal (MHL, MyDP or Display Port or a signal transmitted via HDMI) and a signal transmitted through USB 3.x The pins can be shared.
In this case, a wired video cable and a wired USB 3.x cable can be connected through the same port.
When the user device is a notebook PC, a desktop, etc., a connector for a video signal and a connector for a USB 3.x signal may be separately implemented, or only one of the connectors may be implemented.
And, if the user device is a printer, only USB 3.x can be implemented.
That is, the connector provided in the user device can be variously implemented, and the connector can be implemented in various forms according to the type of the smart device, the manufacturer, and the development of high-speed data transmission technology.
Wired video signals and USB 3.x signals delivered via MHL, MyDP or Display Port or HDMI can all be high-speed serial signals in Giga bps.

The case for a mobile terminal according to an embodiment of the present invention is directly connected to a wired connector of an existing user device and can transmit and receive data wirelessly as well as data is transmitted and received through a wired connection.
For convenience of explanation, the wireless transmission / reception processing unit is assumed to be a separate hardware that can be connected to the connector of the user apparatus, but the wireless transmission / reception processing unit may be implemented directly in the user equipment. In this case, the connector implemented outside the user device can be eliminated, and the waterproof function of the user device can be implemented.
6 is a view illustrating a case for a mobile terminal according to an embodiment of the present invention.
Hereinafter, the operation of the mobile terminal case in the transmitting terminal for transmitting the high-speed wire serial data will be described with reference to FIG.
In the case of a mobile terminal according to an embodiment of the present invention, when a signal based on single channel image data, multi-channel image data or bidirectional channel data is transmitted through a high-speed data transmission unit of a user equipment, The signal processing of the
Accordingly, the case for the mobile terminal can perform a role of a wireless transmission / reception processing device in a transmitting terminal.
The single channel image data signal may be a signal including a data signal and a clock signal, for example, as in the case of MHL 2.0. Accordingly, in order to wirelessly transmit a single channel image data signal having a mixed output, a process of separating a signal from a transmitting terminal and rejoining a signal separated from the receiving terminal is necessary.
When a single channel video data signal in which a clock signal is not mixed is input, the clock data demultiplexer (DEMUX) of the transmitting terminal and the multiplexer (MUX) of the receiving terminal may be unnecessary. Examples of single channel image data signals not mixed with such clock signals include MHL version 2.0 or later, MyDP, and the like.
A clock signal separated from a single channel image data signal in which the clock is mixed in the case of the mobile terminal of the transmitting end is converted into binary binary data (for example, 220022002200) and is transmitted as a preamble before transmission of the original data signal. And may be transmitted through the RF unit.
(Differential signal) based on the single channel image data (for example,
In addition, in the mobile terminal case of the transmitting terminal, signals (differential signals) based on multi-channel image data (e.g., Display Port 450) can be transmitted to the receiving / transmitting apparatus through the four Tx RF units.
(Differential signal) based on bidirectional channel data (for example, USB 3.x (470)) can be transmitted to the wireless transmission / reception processing device of the receiving end through one Tx RF part in the case of the mobile terminal of the transmitting end .
Here, the Tx RF unit and the Rx RF unit for transmission of the USB3.x (470) based signal can be configured as a pair.
The Tx RF unit and / or the Rx RF unit may be selected through switching according to an input signal, and a signal input through the selected Tx RF unit and / or the Rx RF unit may be transmitted through the wireless medium. Specifically, the signal processor determines the signal format of an input signal, and determines ON / OFF of a plurality of RF units included in the data signal radio transmission / reception unit. Each of the plurality of RF units included in the data signal radio transmission / reception unit in which ON / OFF is determined according to the format of the input signal can transmit wireless data through the set frequency band.

The connection request message 900 may include battery information of the second user equipment, information on whether the second user equipment is continuously charged, and information on the transmission strength of the connection request message.
The case for the mobile terminal which has received the connection request message 900 through the second wireless transmission / reception processing device may transmit the
The case for the mobile terminal (or first user device) is based on the received strength of the received connection request message 900, battery information of the second user device, information on whether the second user device is continuously chargeable, The final transmission signal strength to be used in the transmission of the radio signal of the second WTRU can be determined.
Specifically, for example, the case for a mobile terminal may include a case for a mobile terminal and a case for transmitting a connection request message 900, based on the information about the transmission strength of the received connection request message 900 and the reception strength of the connection request message 900 Can be predicted.

For example, if the second user equipment is continuously in the chargeable state, the final transmitted signal strength may be a value that is greater than the first transmitted signal strength by a certain percentage. If continuous charging is possible, stable high-speed wired serial data transmission can be performed by using a relatively high transmission signal strength.
If the second user device is not continuously in the chargeable state, the final transmitted signal strength may be determined based on the battery charge state. For example, when the charge amount of the current battery is equal to or greater than a threshold value (for example, 70%), the final transmitted signal strength may be determined to be the same value as the first transmitted signal strength. Conversely, when the charge amount of the current battery is less than a threshold value (for example, 70%), the final transmitted signal strength may be determined to be a value smaller than the first transmitted signal strength.
