    摘要: A data slot allocation method allowing a plurality of devices in a wireless personal area network (WPAN) to satisfy the required QoS condition for the data stream transmission. The method includes allocating a specific number of data slots of a superframe to the plurality of the devices based on the QoS information; additionally allocating a certain number of data slots to a first device when the first device transmitting a data stream is allocated data slots less than a number of required data slots for the data stream transmission; and reserving the additional data slots for the first device by reducing a number of data slots to be allocated to the other devices, excluding the first device. Accordingly, the data slots can be fairly distributed to the devices.

    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 signal reception apparatus and method for communication systems. The signal reception apparatus for communication systems according to the present invention is applicable to communication environments in which a plurality of sub-bands having different frequency bands are sequentially used for communications. An embodiment of the invention has a multi-band index generation unit, a multi-band frequency generation unit, a multiplication unit, a correlation signal reception unit, and a buffer unit. The multi-band index generation unit generates a multi-band index corresponding to a sub-band to which a received signal is transmitted in correspondence with the multi-band index. The multiplication unit outputs a signal obtained by multiplying the received signal by the multi-band frequency. The correlation signal reception unit integrates and outputs the signal of the multiplication unit based on an integral time set in correspondence with the multi-band index. Further, the buffer unit buffers the signal of the correlation signal reception unit to be outputted at a predetermined data rate.

    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.

    摘要: A method for reserving non-colliding time slots by a node in a wireless network and a method for avoiding colliding time slots are provided. A transmitting node or a receiving node broadcasts information relating to its reserved time slot to neighbor nodes. A node in the wireless network recognizes information relating to time slots of neighbor nodes and of neighbor's neighbor nodes. Thus, when reserving a time slot for data transmission, time slot collision can be prevented by selecting the time slot based on the recognized information. If collision occurs in the reserved time slot and the node wants to cancel the reservation, the node informs a correspondent node of the reservation cancellation. Accordingly, the collision can be promptly resolved.
