Abstract: Embodiments of the present disclosure propose a solution for availability of system broadcasted information such as GNSS information which can be used for deriving time and/or frequency domain compensation. According to embodiments of this present disclosure, a validity timer for system broadcasted information is introduced in both UE and network to guarantee the system broadcasted information availability status is synchronized in two nodes, and the system broadcasted information is valid to pre-compensate in time and/or frequency domain when the timer is running. In this way, the UE can be scheduled with correct timing and frequency estimation in UL transmission.

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: An apparatus performs evaluating, with a user equipment of a communication network, before detaching from a source cell a conditional handover execution condition fulfillment for a conditional handover with the user equipment from the source cell to at least one target cell of the communication network; and based on the evaluating, detaching from the source cell for performing the conditional handover to a target cell of the at least one target cell. Further, an apparatus performs sending toward user equipment information comprising a configuration of a conditional handover, wherein the information causes the user equipment to evaluate a conditional handover execution condition fulfillment before detaching from the source cell for at least one target cell based on an indication of the conditional handover execution condition fulfillment to a first target cell of the at least one target cell that does not support a dual active protocol stack configuration.

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: 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.
