<P>PROBLEM TO BE SOLVED: To provide an apparatus which improves quality of communications, power efficiency, etc. to address growing demands in CDMA wireless systems. <P>SOLUTION: In a communication system where a CDMA segment at each access point consists of multiple sub-segments, a three frame transmission time interval (TTI) with eight retransmissions is utilized for data transmission. The access point not only specifies the interlaces to be utilized for data transmission but also assigns packet start interlaces for particular access terminals. An auxiliary pilot channel R-AuxPICH is transmitted by an access terminal along with CDMA data on a reverse link. The ratio of R-AuxPICH to R-PICH is varied based on ACK/NACK feedback. The apparatus sets reverse link activity bits (RABs) as an emergency load-control mechanism for non-QoS flows and includes a transmitter which broadcasts the RABs. <P>COPYRIGHT: (C)2012,JPO&INPIT |
