TRANSMISSION, RETRANSMISSION, AND HYBRID AUTOMATIC REPEAT REQUEST PROCESS USING PRECONFIGURED UPLINK RESOURCES IN IDLE MODE

Abstract:

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.
