Title:
BASE STATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2008/041650
Kind Code:
A1
Abstract:
A base station device includes: means for creating a low-layer control channel containing
at least resource allocation information and transmission type information
on a data channel destined to a user device; means for encoding a low-layer control
channel for each of user devices; means for transmitting a data channel and a low-layer
control channel to the user device; and means for deciding a multiplex method
of a downlink radio resource in accordance with the movement degree or the traffic
type of the user device. High-layer control information indicating that the
downlink radio resource multiplex method is a localized FDM method or a distribute
FDM method is transmitted by the data channel.
