Abstract: Systems, methods, apparatuses, and computer program products for physical broadcast channel (PBCH) extension to manage extended master information block (MIB) are provided. A user equipment (UE) may determine whether an MIB extension exists. If the MIB extension exists, then the UE may determine an extended PBCH time-frequency location.

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.

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.

Abstract: A method may include monitoring, by a user equipment, a first wake up signal prior to a paging occasion during a discontinuous reception cycle. The method may also include decoding a physical down-link control channel based on the paging occasion in response to detecting the first wake up signal. The method may also include determining that the decoding failed. The method may further include switching to a common paging occasion to decode the physical downlink control channel after determining that the decoding failed.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for counting of devices. In example embodiments, a first device receives, from a second device, a first configuration associated with an event to trigger transmission of a counting signal from the first device to the second device. When the event occurs, the first device transmits, to the second device, at least the counting signal to enable the second device to count the number of devices for determining a type of signals.

Abstract: Embodiments of the present disclosure relate to communications with preconfigured uplink resources (PUR). A method implemented at a terminal device comprises identifying a need to change a transmission configuration of the terminal device, the terminal device being in a transmission mode with a set of preconfigured uplink resources (PURs) allocated for the terminal device to transmit user data to a network device; and in response to identifying the need to change the transmission configuration, transmitting control information to the network device using a first PUR in the set of PURs, the control information comprising information relevant to the change of the transmission configuration. In this way, it is possible to enable the terminal device to save power, time, and resources by bypassing a full random access procedure when the transmission configuration is needed to be changed.
