Abstract:
1. In a wireless communication system, a method of transmitting ACK/NACK information in Fast ACK/NACK reporting (FANR) mode, the method comprising: receiving a command from a network by a mobile station to operate in event-based FANR mode, wherein the event-based FANR mode is defined as ACK/NACK information for a downlink data block is included in an uplink data block and transmitted if unreported ACK/NACK state for the downlink data block is detected in an instance of not receiving, from the network, a polling message requesting the transmission of ACK/NACK information; determining whether there is at least one uplink data block to be transmitted; if there is the at least one uplink data block to be transmitted, determining an ACK/NACK state for the at least one uplink data block to be transmitted; and if the ACK/NACK state is a tentative ACK state for the at least one uplink data block to be transmitted, transmitting an ACK/NACK signal for the downlink data block in an uplink control message by the mobile station in event-based FANR mode, instead of a transmission of the uplink data block including the ACK/NACK information for the downlink data block.
