CONTROLLING AUTOMATIC HYBRID REQUESTS FOR REPEATED TRANSMISSION IN ASCENDING CHANNEL OF WCDMA SYSTEM DURING RECONFIGURATION OF TRANSMISSION INTERVAL DURABILITY

摘要

FIELD: information technologies.;SUBSTANCE: reconfiguration of TTI (time transmission interval) durability of the ascending channel is delayed until all the non-completed repeated transmissions are successfully completed or until maximum number of transmissions is achieved. Transmission of new packets is stopped for this time period but non-completed repeated transmissions are allowed. After the subscriber equipment receives ACK/NACK (acknowledgement of receipt/non-acknowledgement of receipt) for each process of hybrid automatic request for repeated transmission (HARQ) or certain maximum number of repeated transmissions is achieved, the subscriber equipment will start transmitting with new TTI durability of the ascending channel.;EFFECT: minimising data losses and eliminating long delays during reconfiguration of durability of the time transmission interval of the ascending channel in radio interface of packet data transmission via ascending channel in the system with broad-banded multiple access and code channel separation.;28 cl, 10 dwg
