Abstract: A mobile terminal including a user input unit configured to input information into the mobile terminal; a display unit configured to display data; a Wi-Fi module configured to provide an Access Point (AP) function such that an external terminal can access a wireless network through the Wi-Fi module providing the AP function; and a controller configured to control a state of the Wi-Fi module to be switched between 1) a power saving mode in which the Wi-Fi module is alternated between a sleep state and an awake state and 2) a power saving off mode in which the Wi-Fi module is continuously maintained in the awake state until a Wi-Fi connection request signal is received from the external device or a predetermined amount of time passes from a specific timing point.

Abstract: In the MS apparatus for performing scheduling, a reception module receives any number information through a specific downlink channel in a first time unit from each of neighbor BSs. A scheduling module determines, among the neighbor BSs, a BS which is to transmit and receive data using a downlink data transmission region and an uplink data reception region, respectively, in a second time unit according to a previously set rule based on the number information. A transmission module transmits a signal, indicating that data transmission and reception using the downlink transmission region and uplink data reception region, respectively, in the second time unit are not possible, to the other neighbor BSs excluding the determined BS among the neighbor BSs.

Abstract: An apparatus and method for transmitting data by using Multi-round Contention Avoidance (MrCA) are provided. The method includes initializing a contention window for each of a plurality of contention rounds and setting a backoff counter corresponding to a size of the contention window for each contention round, starting from a first contention round to a last contention round, decrementing a backoff counter of a corresponding contention round in a time slot unit and transmitting data when the decremented backoff counter is zero and when the corresponding contention round is a last contention round. Accordingly, the number of contending nodes is exponentially decreased for each contention round, resulting in significant decrease in a collision probability in addition to improving fairness on channel use among users.
