ACK CHANNEL DESIGN FOR EARLY TERMINATION OF R99 DOWNLINK TRAFFIC

摘要

A method of transmitting acknowledgements on certain slots of the R99 uplink DPCCH channel for traffic packets sent on the R99 downlink channel, by replacing the TPC bits by Ack bits transmitted with on-off keying, applying a pre-configured boost to the transmit power of the entire slot in which an Ack has to be transmitted, or to only the Ack symbol in that slot, and not applying any boost to slots not reserved for Ack/Nack transmission or slots in which a Nack has to be sent; and modifying the NodeB receiver algorithms to account for the extra power boost once the Ack/Nack detector detects that an Ack has been transmitted in a given slot.
