Abstract: Certain aspects of the present disclosure provide techniques for performing a public land mobile network (PLMN) selection procedure based on allowed PLMN(s) in a particular country of a user equipment (UE). An example method generally includes determining a country in which the UE is located, creating a list of available PLMNs, that are allowed to be selected in the country in which the UE is located, for access to a non-terrestrial network (NTN), and performing a PLMN selection procedure for access to the NTN based on the list of available PLMNs and the country in which the UE is located.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a duration of a first gap that precedes a reference signal, based at least in part on a polarization of the reference signal. The UE may determine a duration of a second gap that succeeds the reference signal, based at least in part on the polarization of the reference signal. The UE may perform a measurement of the reference signal based at least in part on the first gap and the second gap. Numerous other aspects are provided.

Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an offset associated with a propagation delay in a network, wherein hybrid automatic repeat request (HARQ) feedback is enabled at the UE, and may monitor for a retransmission of a downlink communication in the network according to the offset. In some aspects, a UE may start a timer associated with monitoring for a retransmission of a downlink communication in a network, wherein HARQ feedback is disabled at the UE, and may monitoring for the retransmission of the downlink communication after starting the timer or after expiration of the timer. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive cell characteristic information of multiple network nodes associated with different network architectures. The UE may select a network node, from the multiple network nodes, based at least in part on a mapping rule and the cell characteristic information, wherein the mapping rule is associated with UE information and cell or network information. The UE may transmit a random access channel (RACH) message to establish a connection with the network node. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications at a network entity. The network entity is configured to transmit a legacy paging message to a user equipment via a first set of resources, and a pre-paging message to a user equipment via a second set of resources. The second set of resources is used if one or more conditions are met. The network entity can also perform one or more actions after transmitting the pre-paging message.

Abstract: The apparatus may be a wireless device configured to receive a set of security parameters associated with one of a layer 1 (L1) link reestablishment procedure or a layer 2 (L2) link reestablishment procedure, detect a failure of a radio link at the wireless device. The apparatus may further be configured to transmit, for a network node, at least one of an L1 link recovery request or an L2 link recovery request, including an authentication value based on the set of security parameters, and receive, based on at least one of the L1 link recovery request or the L2 link recovery request, a link recovery message.

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.
