Abstract:
A method for waking a device from a power save mode to an active mode includes: transmitting, by a first device, a magic packet through a predetermined channel to a second device, which operates in the power save mode by repeating a doze state and an awake state according to a predetermined period of time, for notifying the second device to switch to the active mode; and retransmitting the magic packet to the second device through the predetermined channel if a response to the magic packet has not been received from the second device and a predetermined time has not elapsed after transmitting the magic packet through the predetermined channel.
Abstract:
A method and apparatus for transmitting urgent data by embedding the urgent data in normal data is provided. An urgent data signal is embedded in a normal data signal in such a way that the normal data signal is not affected, and then the urgent data signal is transmitted together with the normal data signal thereby stably transmitting urgent data without using a separate urgent data line.
Abstract:
A method and apparatus for reducing power consumption by controlling listening periods in a wireless telecommunications device having a plurality of power-saving modes are provided. The method includes: setting a first power-saving mode and a second power-saving mode, each of the first and second power-saving modes having a power-saving mode period in which power is saved and data is not transmitted and received, and a standby period in which data is transmitted and received; detecting the standby mode periods from the first and second power-saving modes; adjusting starting periods of the first and second power-saving modes so that the detected standby mode periods of the first and second power-saving modes overlap; and controlling power according to the adjusted first and the second power-saving modes.
Abstract:
A method and an apparatus are provided for enabling a legacy station to perform virtual carrier sensing when a plurality of stations with heterogeneous capabilities coexist in a wireless network. The method includes receiving first data via a bonded channel formed by channel bonding first and second adjacent channels, and transmitting second data via each of the first and second adjacent channels, the second data being a clear-to-send (CTS) frame or a request-to-send (RTS) frame.
Abstract:
The present invention relates to novel thiazolothiazole derivatives and an organic electronic device such as an organic light emitting device, an organic transistor, and an organic solar cell using the same. In the compound of the invention, various substituents are introduced to the core structure, so as to satisfy the requirements such as suitable energy levels, and electrochemical and thermal stability, and also have amorphous or crystalline property depending on the kind of the substituents, so as to satisfy the characteristics individually required for each of the devices. Further, an organic semiconductor of p-type or n-type can be fabricated by introducing various substituents to the core structure having a property of n-type. Therefore, the compound of the present invention can provide a device having higher stability.
Abstract:
Provided are a method and an apparatus for generating an acknowledgement (ACK) frame. The method includes: receiving a data frame; first determining whether sub-frames included in the received data frame are coded in an unequal error protection (UEP) mode; and based on the determination of the first determining, generating the ACK frame including a first ACK field indicating reception of each of the sub-frames or second ACK field indicating reception of each first type bit and second type bit in the sub-frames.
