Abstract: Certain aspects of the present disclosure provide techniques for communicating user equipment (UE) capability information in wireless communication networks. An exemplary method performed by a UE includes receiving, from a network entity, a request for capability of the UE and transmitting, in response to the request, a UE capability message that differentiates sets of features the UE supports in different network types.

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.
