摘要： An apparatus and method for generating an intermediate frequency (IF) to be transferred to a single sideband (SSB) generator which generates carriers using one local oscillator (LO) signal and at least two IF signals that are received. A group signal is generated which includes a non-phase-shifted signal and a phase-shifted signal to a predetermined value with respect to each IF. One of the group signals is selected and transferred to the SSB generator. Accordingly, the SSB generator performs the phase shift on the LO signal alone.

摘要： A method for transmitting data from a second device to a first device in a communication system including at least two devices that enter a sleep mode and a wake-up mode in an alternative manner. The first device of which state is changed from the sleep mode to the wake-up mode broadcasts a message containing state change information to adjacent devices. The second device that receives the message containing the state change information informs the first device of the presence of data to be transmitted. The first device that is informed of the data to be transmitted sends a message permitting the data transfer. The second device upon receiving the message transmits the data to the first device.

摘要： A wireless communication apparatus capable of adjusting a time interval between slot sections in accordance with the amount of traffic in a piconet. The wireless communication apparatus has a transceiver for sending and receiving data to and from an external device, a beacon channel generator for generating a train of beacon slots during a park mode, with a constant interval, a slot section calculator for calculating the time interval of the trains of beacon slots consecutively generated based on a coefficient of slot utilization and a wakeup ratio, and a controller for controlling the beacon channel generator for allowing the trains of beacon slots to be generated at the time interval calculated by the slot section calculator. The beacon channel generator sets up an access window for activating the data communication with the external device, after the trains of beacon slots are generated. Accordingly, the wireless communication apparatus can cope with the change of traffic characteristics of piconet environment, as the time interval of the trains of beacon slots can be adjusted according to the coefficient of slot utilization and the wakeup ratio of the slot section.

摘要： A method and system for determining a state of a first node in a wireless network consisting of a plurality of nodes. The first node determines one of at least two power sensitivity levels by considering at least one of an available power and a standby packet. The first node determines whether it remains in active state or inactive state by considering a power sensitivity level transmitted from at least one second node which corresponds to the first node and the determined power sensitivity level. Also, the corresponding node has an identical state to the first node, so that unnecessary power consumption can be prevented.
