Packet data transmitting method and mobile communication system using the same
View Patent ↗A packet data transmitting method and mobile communication system using the same enables transmission of common ACK/NACK information from each sector of a base station to a user entity in softer handover. The method includes receiving via at least one of the plurality of sectors a data packet from the mobile terminal, the data packet being correspondingly received for each of the at least one of the plurality of sectors; combining the correspondingly received data packets, to obtain a signal having a highest signal-to-noise ratio; decoding the value obtained by the combining; determining a transmission status of the data packet according to the decoding; and transmitting to the mobile terminal a common ACK/NACK signal including one of a common ACK signal and a common NACK signal according to the determining, the common ACK/NACK signal being transmitted via each of the at least one sector.
1. A method of processing hybrid automatic repeat request (HARQ) feedback information in a mobile communication system, the method performed by a base station and comprising:
receiving an enhanced dedicated channel (E-DCH) signal;
decoding the received E-DCH signal; and
transmitting two or more acknowledgment/non-acknowledgment (ACK/NACK) signals via two or more cells associated with the base station,
wherein the two or more ACK/NACK signals have a same value.
2. The method of claim 1 , wherein the E-DCH signal is received via each of the two or more cells associated with the base station.
3. A base station operated in a mobile communication system having a plurality of cells associated with the base station, the base station comprising:
a receiver configured to receive an enhanced dedicated channel (E-DCH) signal;
a decoder configured to decode the received E-DCH signal; and
a transmitter configured to transmit two or more acknowledgment/non-acknowledgment (ACK/NACK) signals via two or more of the plurality of cells associated with the base station,
wherein the two or more ACK/NACK signals have a same value.
4. The base station of claim 3 , wherein the receiver is further configured to receive the E-DCH signal via each of the two or more of the plurality of cells associated with the base station.
5. A method of processing hybrid automatic repeat request (HARQ) feedback information in a mobile communication system, the method performed by a base station and comprising:
receiving enhanced dedicated channel (E-DCH) signals via two or more cells associated with the base station;
combining the received E-DCH signals into a combined signal;
decoding the combined signal; and
transmitting two or more acknowledgment/non-acknowledgment (ACK/NACK) signals via the two or more cells based on the decoding of the combined signal,
wherein the two or more ACK/NACK signals have a same value.
6. A base station operated in a mobile communication system having a plurality of cells associated with the base station, the base station comprising:
a receiver configured to receive enhanced dedicated channel (E-DCH) signals via two or more cells associated with the base station;
a controller configured to combine the received E-DCH signals into a combined signal;
a decoder configured to decode the combined signal; and
a transmitter configured to transmit two or more acknowledgment/non-acknowledgment (ACK/NACK) signals via the two or more cells based on the decoding of the combined signal,
wherein the two or more ACK/NACK signals have a same value.
