Abstract:
A base station broadcasts information of an entire discontinuous signal transmission duration and information of a discontinuous signal transmission interval to a plurality of terminals, and stops transmission of a downlink control signal and data for at least some interval of the discontinuous signal transmission interval.
Abstract:
In a wireless communication system where a terminal and a base station communicate with each other using a frame including at least one downlink sub-frame and at least one uplink sub-frame, the terminal and the base station calculate the number of hybrid automatic repeat request (HARQ) feedback regions of the downlink sub-frames and the uplink sub-frames in accordance with a third value corresponding to an absolute value of subtraction between a first value corresponding to the number of downlink sub-frames of the frame and a second value corresponding to the number of uplink sub-frames of the frame or the sum of the first value and the second value and configure HARQ feedback regions in the downlink sub-frames and the uplink sub-frames.
Abstract:
Disclosed is a fine motion estimation device for high resolution including: a previous picture storage memory in which search area data of previous pictures for macroblocks of current pictures are stored; an FIR filter configured to perform FIR filtering on the search area data stored in the previous picture storage memory; a memory configured to differentiate and store the FIR filtered search area data; a QME data processing unit configured to generate reference area data for motion estimation in a ¼ pixel unit; a processing array unit configured to perform motion estimation in a ½ pixel unit and the macroblocks transmitted from the FIR filter and motion estimation in the ¼ pixel unit; and a control unit configured to control operations of the FIR filter, the processing array unit, and the QME data processing unit.
