TRANSCEIVER APPARATUS AND METHOD FOR SOFT HANDOVER AND SOFTER HANDOVER IN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEM

摘要

The present invention is an orthogonal frequency division in a communication system using a multiple access scheme on the soft / softer and uplink data burst transmission method and the transceiver structure of a downlink for handover. The present invention, DL, assigns the plurality of PUSC sub-channel to the terminal in each sector included in the active set and send the same data, and the terminal receiver in the soft combining of the plurality of PUSC sub-channel signals (soft combining ) by soft handover or softer implements the handover, an uplink, assigns the PUSC sub-channel corresponding to the PUSC area of ​​a sector among the sectors included in the active set to the terminal, the terminal is allocated PUSC subchannel to transmit data, receives the plurality of base stations or a plurality of the uplink signal sectors and characterized in that it implements a soft handover or softer handover, also for the implementation of the soft handover and softer handover soft in an OFDMA system using a transmitter / receiver of the transmission of the required terminal / receiver of a base station and a handle Implement the de-over and softer handover, characterized in that to prevent the received signal quality of the terminal and the disadvantages of a ping-pong (ping-pong) development of hard handover in the cell edge.
