METHOD AND APPARATUS FOR TIME-BASED EGPRS RESPONSE CONFIGURATION

摘要

PROBLEM TO BE SOLVED: To provide a method for time-based fast positive ACK/NACK response (FANR) operation with EGPRS-2 uplink (HUGE).SOLUTION: A WTRU configures downlink FANR operation and EGPRS-2 mode uplink transmission not to be in conflict. A modulation and coding scheme (MCS) for the EGPRS-2 mode may be limited to an MCS containing at most two RLC data blocks. Alternatively, three or more piggybacked ACK/NACK (PAN) bits may be used for a time-based FANR operation if the EGPRS-2 mode is in conflict. Alternatively, a PAN bit may indicate an ACK/NACK for a group of RLC data blocks. The number of PAN bits for a time-based FANR operation may be configured by the network.
