Abstract: This disclosure provides methods, components, devices and systems for enhanced downlink and uplink scheduling based on assistance information related to PDCP status reports. Some aspects specifically relate to a wireless communication system including a disaggregated base station architecture in which a CU provides a DU assistance information related to PDCP status reports from which assistance information the DU may determine appropriate downlink or uplink scheduling start timing for a UE. In some examples, the DU obtains from the CU assistance information indicating an unreceived PDCP SDU at a UE or the CU, and sends downlink data or an uplink grant to the UE based on the assistance information. The CU may deliver the downlink data to the DU prior to sending the assistance information or obtain uplink data from the DU after sending the assistance information. Duplication of PDCP SDU transmissions and unnecessarily extended scheduling delays may thus be minimized.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a control message indicating one or more parameters associated with selecting one or more cells. The UE may select one or more first cells to monitor for a paging message based on the one or more parameters and may monitor the one or more first cells for the paging message in an idle mode, inactive mode, or any non-connected mode based on the selection. Additionally, the UE may select one of the one or more first cells or a second cell to establish a connection based on monitoring for the paging message and may establish the connection with the one of the one or more first cells or the second cell based on the selection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating whether hybrid automatic repeat request (HARQ) feedback is disabled for one or more HARQ processes. The UE may receive a downlink communication. The downlink communication may include a HARQ process identifier that indicates a HARQ process to be used for the downlink communication. The UE may selectively provide HARQ feedback for the downlink communication based at least in part on the HARQ identifier and information indicating whether HARQ feedback is disabled for the HARQ process. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for bandwidth part (BWP) switching by frequency shifting and/or by transmission configuration indicator (TCI) state configuration. A method that may be performed by a user equipment (UE) includes receiving a BWP configuration indicating a frequency location and bandwidth of at least a first BWP; receiving signaling indicating at least one frequency shift to determine a second BWP from a frequency location of the first BWP; and communicating on the second BWP after performing a BWP switch from the first BWP to the second BWP based on the at least one frequency shift.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may access a serving network via a satellite while in a first state with the serving network, the first state comprising a connected state. The UE may transmit, to the serving network and based on a determination that a coverage gap associated with the satellite is upcoming, a coverage gap indication that indicates that the coverage gap is upcoming. The UE may transition from the connected state to a second state at or before a start of the coverage gap. Numerous other aspects are described.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a UE in NTN are provided. The UE may be configured to receive one or more FPC commands from an NTN. The UE may be further configured to transmit, in response to receiving the one or more FPC commands, an uplink transmission with a frequency change having a total FPC adjustment calculated based on (a) a current UE location update and a current UE velocity update, wherein the total FPC adjustment satisfies one or more threshold requirements, or (b) an intermediary UE location update between the current UE location update and a previous UE location update and an intermediary UE velocity update between the current UE velocity update and a previous UE velocity update.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

Abstract: Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes performing a mobility procedure to establish a connection in a target radio access technology (RAT) while maintaining a context established in a source RAT, wherein one of the source RAT or target RAT is a terrestrial network (TN) RAT and the other is a non-terrestrial network (NTN) RAT and sending a tracking area update (TAU) request after establishing the connection in the target RAT.
