Methods and apparatus for sending fast negative acknowledgements (NACKs)

An apparatus for wireless communication, comprising:

• means for determining that a trigger event has occurred;
• means for modifying a negative acknowledgement (NACK) timing configuration by initializing a time period of an aggressive NACK timing configuration, wherein during the time period, NACKs for one or more missed packets are transmitted quicker relative to a default NACK timing configuration;
• and
• means for transmitting one or more NACKs in accordance with the modified NACK timing configuration.

An apparatus for wireless communication, comprising:

• at least one processor configured to:
• determine that a trigger event has occurred;
• in response to the determination, modify a negative acknowledgement (NACK) timing configuration by initializing a time period of an aggressive NACK timing configuration, wherein during the time period, NACKs for one or more missed packets are transmitted quicker relative to a default NACK timing configuration;
• and
• transmit one or more NACKs in accordance with the modified NACK timing configuration;
• and
• a memory coupled to the at least one processor.

A non-transitory computer-readable medium for wireless communication by a user equipment (UE), storing instructions which when executed by at least one processor performs a method comprising:

• determining that a trigger event has occurred;
• in response to the determination, modifying a negative acknowledgement (NACK) timing configuration by initializing a time period of an aggressive NACK timing configuration, wherein during the time period, NACKs for one or more missed packets are transmitted quicker relative to a default NACK timing configuration;
• and
• transmitting one or more NACKs in accordance with the modified NACK timing configuration.
