A UE may be enabled to provide low latency, high reliability, and power savings. If a message of the UE is delay-sensitive, the UE may indicate to a gNB that fast retransmission scheduling may be necessary if a packet is not received over PUSCH. After transmitting the packet, the UE may monitor PDCCH for an indication that retransmission is required. This monitoring may occur sooner than a PDCCH monitoring period would otherwise allow. If the UE receives a DCI indicating that retransmission is required, the UE may retransmit the packet as well as an indication for a fast transmission request. This process may continue until an acknowledgement of the received packet is received in DL or no DCI indicating retransmission is received in DL. Accordingly, the gNB may quickly receive the retransmitted packet while the UE saves power by only performing additional monitoring when requested.
