DATA COMMUNICATION DEVICE DATA COMMUNICATION METHOD

摘要

A data communication device not causing transmission delay of information transmitted from a mobile station in response to the received information from a base station and capable of expanding the radius of the communication zone of the base station. A base station (100) having the data communication device performs scheduling of assigning both a downstream slot (122) and an upstream slot (123) to each mobile station according to the downstream/upstream traffics and further assigning a slot (124) for another mobile station between the downstream and upstream slots (122, 123) in the same frame.
