Abstract: This disclosure provides systems, methods and apparatuses for early measurement associated with configuring with multiple secondary nodes (SNs). In one aspect, the configuration of multiple SNs may be improved by allowing a master node (MN) to determine a multi-SN configuration based at least in part on measurements of actual channel conditions as seen by the UE. Enabling the MN to receive the measurement information early during a process associated with establishing a connection between the UE and the MN may thereby improve efficiency and reduce latency associated with the configuration of multiple SNs.

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: Methods, systems, and devices for wireless communications are described. The method may include receiving from a master cell group of a dual connectivity environment a first message indicating that a secondary cell group of the dual connectivity environment is suspended, maintaining a lower layer configuration for the secondary cell group and modifying a measurement report configuration for the secondary cell group based on the first message and while the secondary cell group is suspended, receiving from the master cell group a second message indicating that the secondary cell group is no longer suspended, and reconnecting to the secondary cell group using the lower layer configuration for the secondary cell group based on the second message.

Abstract: The disclosure relates to reduced signaling to carry out the linking between new radio (NR) carrier aggregation (CA) band combinations and NR band processing combinations (BPCs), and includes apparatus and methods of receiving, at a modem of a user equipment (UE), a UE configuration from a base station based on UE band combination constraint information, configuring the UE, by a processor of the UE, according to the UE configuration, and performing a communication with the base station, via the modem of the UE, according to the UE configuration. In an implementation, the disclosure includes transmitting the UE band combination constraint information, such as in the form of receiving a total number of layers supported in a CA band combination, and wherein receiving the UE configuration further comprises receiving a CA combination and a BPC configuration in response to the UE band combination constraint information.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.
