Abstract:
A method may include transmitting, by a user equipment, a data packet to a network entity. The method may further include starting, by the user equipment, a timer with a first value associated with the transmission to the network entity. The method may further include checking, by the user equipment, for feedback from the network entity associated with the transmission to the network entity. The method may further include determining, by the user equipment, that no feedback for the transmission has been received within the associated timer, or a negative acknowledgement has been received without the corresponding resource allocation for re-transmission. The method may further include in response to receiving no feedback associated with the transmission within the associated timer, or receiving a negative acknowledgement without the corresponding resource allocation for re-transmission, re-transmitting, by the user equipment, the data packet to the network entity.
