Description

Mobile terminal and its channel allocation method {MOBILE TERMINAL AND CHANNEL ALLOCATION METHOD THEREOF}

The present invention relates to a mobile terminal capable of using Wi-Fi without throughput degradation by assigning a MAC to a switched individual channel signal in a mobile communication terminal having multiple antennas, and a method of allocating the same. It is about.

The mobile terminal may be configured to perform various functions. Examples of such various functions include a data and voice communication function, a function of photographing a video or a moving image through a camera, a voice storage function, a music file playback function through a speaker system, and an image or video display function. Some mobile terminals include additional functionality to play games, while others are implemented as multimedia devices. Moreover, recent mobile terminals can receive broadcast or multicast signals to watch video or television programs.

Further, efforts for supporting and increasing the functions of the mobile terminal continue. The foregoing efforts include not only changes and improvements in the structural components forming the mobile terminal, but also improvements in software or hardware. Among them, the touch function of the mobile terminal allows a user who is unfamiliar with the button / key input to conveniently perform the operation of the terminal by using the touch screen. In recent years, not only simple input but also user interface (UI) Is becoming an important function of Accordingly, as the touch function is applied to a mobile terminal in various forms, development of a user interface (UI) corresponding thereto is further demanded.

With the development of information and communication technology, various wireless communication technologies are being developed. Among them, WI-FI is a local area network (LAN) that allows at least one station (STA) to use high-speed Internet within a certain distance of a place where a wireless access device (AP) is installed. At this time, the station is used in the same meaning as the mobile communication terminal, the AP may be used in the same meaning as the base station (BS) within 30-300m.

Recently, due to the rapid growth of the wireless mobile communication market, various multimedia services are required in a wireless environment, thereby increasing the capacity of the transmission data and increasing the speed of data transmission. Therefore, finding a way to efficiently use the limited frequency resources in order to effectively provide various multimedia services has emerged as the most urgent task. To solve these problems, a multiple input multiple output (MIMO) system using multiple antennas has been used. .

Therefore, in order to transmit a large amount of data at high speed and perform high-speed Internet within a certain distance, MIMO technology and WI-FI technology have been applied to mobile terminals.

As the Wi-Fi function is expanded in the mobile terminal, 5GHz is added in addition to the 2.4GHz band in terms of frequency, and in addition to P2P and Soft-AP in terms of features, a plurality of modes, namely, Wi-Fi Direct (WFD) and AP- STA mode has been added.

The Wi-Fi Direct has a similar function to Bluetooth and has a wider transmission range and faster data transmission rate than Bluetooth. The AP-STA mode means a mode capable of two modes, namely, an AP mode and a STA mode. At this time, the AP mode is a mode using the P2P mode through the wireless access device (AP), the STA mode is a mode using the Internet browsing by using the wireless Internet.

3 shows a schematic MAC structure for showing a conventional channel allocation method when using multiple modes.

As shown in FIG. 3, when performing a plurality of modes, that is, the AP-STA mode, conventionally, two MACs (Media Access Control) are allocated to one channel, and the AP mode and Internet browsing are utilized. STA mode was used simultaneously. In this case, each MAC is connected between the physical layer and the data link layer where the transmission / reception data is actually transmitted and received to perform the partitioning and connection function of the data to be transmitted and received.

However, in the conventional channel allocation method, the Wi-Fi function is extended to add a separate frequency (5 GHz) and applied to one channel when multiple modes (Wi-Fi Direct (WFD) and AP-STA modes) are used. The amount of data that is added increases throughput. This throughput degradation degrades Wi-Fi, and this situation is further exacerbated when multiplexing channel signals with MIMO.
