A remote control transceiver is described. The remote control transceiver reduces costs by simplifying a structure of a conventional space movement remote controller including an acceleration sensor, a microprocessor, a radio transmitting unit, and a radio receiver. A grid pattern formed by a light emitting diode (LED) and an optical system of a transmitter is determined by an infrared sensor of a receiver to discern space movement location information of the transmitter. The remote control transceiver includes a remote control transmitter and a remote control receiver. The remote control transmitter includes a key input unit for receiving commands, an LED driver for controlling the operation of an LED in response to a command signal generated from the key input unit, and a pattern generator for generating a grid pattern using light generated from the LED. The remote control receiver detects a moving direction and a moving distance using the grid pattern received from the remote control transmitter, and generates location information corresponding to the moving direction and distance.

A system is disclosed, that provides dynamic bandwidth sharing among a plurality of client nodes, which share network link resources in a communication network. Upon receipt of a bandwidth adjustment request from a requesting client node, the system adjusts bandwidth when network link capacity meets the bandwidth adjustment request, or when total amount of bandwidth offered to trade by any peers of the requesting client node meets the bandwidth adjustment request.
摘要:
In a wireless communication system, an apparatus and method for managing an uplink communication between a network and a plurality of terminals is achieved by transmitting a response condition parameter from the network to the plurality of terminals subscribing to a multicast service. The parameter is associated with controlling the uplink communication of the plurality of terminals. The terminals then applies the response control parameter to a predetermined test and responds to the network if the terminal determines that it is qualified to respond to the network in response to a result of the predetermined test. The network evaluates whether the parameter needs to be transmitted to the plurality of terminals and whether the parameter needs to be updated based on at least part of responses received by the network.
