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.

Abstract: A system, apparatus, method, and non-transitory computer readable medium for providing transfer block indications in uplink (UL) grant-free transmissions may include a memory having computer readable instructions stored thereon, and at least one processor configured to execute the computer readable instructions to transmit a first transport block (TB) to a base station (BS) during a first transmission time interval (TTI) using a grant-free UL transmission, receive a UL grant from the BS in a physical downlink control channel (PDCCH) region during a time window, determine a target of the UL grant, the target including at least one of the first TB, a second TB, or a previously transmitted TB, based on the UL grant, and transmitting the target of the UL grant to the BS.
