Abstract: Systems, methods, apparatuses, and computer program products for over-the-air test for uplink transmit timing adjustment in wireless systems. A method may receiving, from a testing device, a configuration with or without a flag indicating that an uplink timing adjustment is enabled. The method may also include detecting a first path of a synchronization signal block with a delay corresponding to the target beam. The method may further include adjusting an uplink transmission timing based on the detection of the first path of the synchronization signal block.

Abstract: There are provided measures for improvement of linear beam sweeping in high speed scenarios. Such measures exemplarily comprise setting a second beam width characteristic of a second beam of a beam sweep, wherein said setting includes calculating said second beam width characteristic based on a first beam width characteristic of a first beam of said beam sweep and a ratio between a first path loss of said first beam between an antenna and a first position at a linear trajectory to be covered by said beam sweep and a second path loss of said second beam between said antenna and a second position at said linear trajectory.

Abstract: According to embodiments, a user equipment (UE) receives a sounding reference signal (SRS) configuration. The SRS configuration includes a first SRS configuration that is used by the UE in a radio resource control (RRC) connected state for SRS transmission and a second SRS configuration that is usable by the UE in an RRC inactive state for SRS transmission with a plurality of cells within a positioning validity area. The UE, while in the RRC connected state, performs a first SRS transmission with a first cell of the plurality of cells based on the first SRS configuration. The UE determines that the UE is in the RRC inactive state. The UE, while in the RRC inactive state, performs a second SRS transmission with one or more cells of the plurality of cells based on the second SRS configuration.

Abstract: A technique including: determining at a user equipment that a current non-terrestrial cell belonging to a network has become unavailable to the user equipment; and determining whether to initiate a cell search based on at least information at the user equipment about timing of availability to the user equipment of one or more other non-terrestrial cells belonging to the network.

Abstract: A determination is made, for a base station that transmits on an operating frequency, whether a radiation pattern of each of one or more neighboring frequencies is correlated with a radiation pattern of the operating frequency. In response to a determination that the radiation pattern of each of the one or more neighboring frequencies is correlated with that of the operating frequency, a computation is made of a total radiated power estimate of each of the one or more neighboring frequencies by performing a beam-based directions procedure for the base station. The total radiated power estimates of each of the one or more neighboring frequencies are output.

Abstract: There is provided an apparatus comprising at least one processor; and at least one memory storing instruction that, when executed by the at least one processor, cause the apparatus, which is configured to communicate on a source transmission configuration indication state, to: receive, from a network using the source transmission configuration indication state, a configuration for a state switch from the source transmission configuration indication state to a target transmission configuration indication state; determine that the apparatus is operated in a high speed train frequency range 2 (HST FR2) scenario; determine whether or not the target state is among active transmission configuration indication states; determine a state switch delay based on determining that the apparatus is operated in the HST FR2 scenario and based on determining whether or not the target state is among active transmission configuration indication states.

Abstract: In an embodiment, two retro-focus lens systems are configured to provide a stereoscopic image. In an embodiment, each retro-focus lens system has a low power negative lens group with a long focal length. In an embodiment, each retro focus lens system has an optical component mounted with three points. One optical component is associated with a first of the two retro-focus lenses. The three points may be loosened, such that the optical component may be adjusted in a first direction, which in turn moves the corresponding image in the opposite direction. Another optical component is associated with the other retro focus lens system. The other optical component has a second set of points that may be loosened such that the other optical component may be adjusted in a second direction that is perpendicular to the first direction, moving the corresponding image in the opposite direction from the second direction.
