Abstract: A network node links search spaces, used by a UE to monitor a control channel for control information for the UE, to an on-duration period of a DRX cycle. Resources of one or both of time-frequency resources or periodicity resources for the search spaces are modified via the linking over the on-duration period. The network node configures the UE so the user equipment implements the modified resources during the on-duration period as the user equipment searches the search spaces. A UE receives configuration, defined so the UE implements modification of resources during an on-duration period of a DRX cycle as the UE searches search spaces during the on-duration period. The resources are one or both of time-frequency resources or periodicity resources. The UE monitors the modified search spaces over the on-duration period, as the UE searches a control channel for control information.

Abstract: 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.

The UE may report a prediction of a future LOS/NLOS radio state change based on the estimates of when the previous radio state changes have occurred.

Abstract: Systems, methods, apparatuses, and computer program products for conditional hybrid automatic repeat request (HARQ) acknowledgement (ACK). For instance, a user equipment (UE) may estimate, during reception of a downlink transmission with x repetitions, an amount of extra energy that may be needed to help ensure successful decoding. The UE may then express this estimate as a quantity of repetitions (y) needed for successful reception, and may inform the radio access network (RAN) of this quantity (e.g., at least one round-trip time (RTT) before the last repetition of the x repetitions is sent). The RAN may handle this message as a conditional positive ACK. The RAN may send the quantity of repetitions y, and may implicitly assume an ACK for that TBS after sending the y repetitions. The RAN may send the next transport blocks (TBS) for that HARQ process after completing transmission of they repetitions.
