    Abstract: A user equipment (UE) is configured to establish a network connection including a new radio (NR)-NR dual connectivity band combination wherein a primary cell (PCell) of a primary cell group (PCG) and a primary secondary cell (PSCell) of a secondary cell group (SCG) both operate on frequency range 1 (FR1) and wherein at least one cell of either the PCG or the SCG operates on frequency range 2 (FR2). The UE receives a measurement gap timing advance parameter, selects one subframe from multiple serving cell subframes and determines a starting point for a configured per-frequency range (FR) measurement gap based on the measurement gap timing advance parameter and the selected subframe.

    Abstract: Techniques discussed herein can facilitate beam management for non-terrestrial networks (NTN). One example aspect is A baseband processor, comprising: a memory interface; and processing communicatively coupled to the memory and transceiver interface and, while connected to a base station (BS) within a cell of a non-terrestrial network (NTN) and, where the cell comprises a plurality of bandwidth parts (BWPs) associated with a plurality of beams, configured to perform operations comprising: receiving a signaling from the base station (BS) comprising a channel state indicator reference signal (CSI-RS) configuration associated with a first BWP of the plurality of BWPs, where the CSI-RS configuration comprises a beam measurement configuration for the plurality of beams, switching from a second BWP of the plurality of BWPs to the first BWP according to the CSI-RS configuration and measure one or more of the plurality of beams according to the beam measurement configuration; and generating a measurement report that includes a layer 1 reference signal received power (L1-RSRP) measurement from the measured one or more of the plurality of beams.

    Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

    Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.
