Some embodiments of this disclosure include apparatuses and methods for facilitating a transmission, retransmission, and hybrid automatic repeat request (HARQ) process using preconfigured uplink resources (PUR) in IDLE mode. In some embodiments, user equipment (UE) may establish a first PUR and a second PUR to use in IDLE mode. The UE may transmit uplink data using the first PUR using a HARQ process. The UE may start a PUR retransmission timer and monitor a control channel for an acknowledgement message. The UE may identify an expiration of the PUR retransmission timer prior to receiving the acknowledgement message, and in response, may retransmit the uplink data using the second PUR.

A method for handling a Message A physical uplink shared channel (PUSCH) transmission in a random access channel (RACH) procedure for use in fifth generation new radio (5G NR) wireless communication system includes determining that the Message A PUSCH transmission in a first step of a two-step RACH procedure overlaps with at least one other uplink physical channel transmission and transmitting at least one of the Message A PUSCH transmission or the at least one other uplink physical channel transmission in accordance with a priority rule.
