Abstract: A system is configured for reconfiguration of a Synchronization Signal Block (SSB) pattern. The system is configured for obtaining data including a configuration for a Synchronization Signal Block (SSB) transmission carrying a physical broadcast channel (PBCH), the configuration specifying, for an SSB of the configuration, resource elements (REs) allocated for transmitting a primary synchronization signal (PSS) to a user equipment (UE) and REs allocated for transmitting a secondary synchronization signal (SSS) to the UE.

Abstract: Mechanisms are provided for a user equipment (UE) to determine a transmission frequency or a time advance for an uplink transmission from the UE to a base station in a non-terrestrial wireless network (NTN) without global navigation satellite systems (GNSS) information available to the UE. A communication connection between the UE and a base station can be established. The UE can determine that GNSS information is not available, and report to the base station that the GNSS information is not available. The UE can receive, from the base station, an indication of one or more parameters for an uplink transmission from the UE to synchronize the uplink transmission. The UE can determine, based on a current transmission frequency and the received indication of the one or more parameters, a next transmission frequency and transmit the uplink transmission at the determined next transmission frequency.

Abstract: Indicating repetitions at a UE in an NTN includes decoding a communication indicating a timing relationship value associated with a distance between a serving satellite and a farthest UE in the NTN. A PRACH communication is encoded for transmission. The PRACH communication includes an indication of a number of PRACH repetitions determined based on the timing relationship value. A RAR including an uplink (UL) grant corresponding to the UE and an indication of a number of RAR repetitions is decoded. The number of RAR repetitions is determined based on the timing relationship value. A PUSCH communication including an indication of a number of PUSCH repetitions is encoded. The number of PUSCH repetitions is determined based on the timing relationship value. A content resolution communication including an indication of a number of content resolution repetitions is decoded. The number of content resolution repetitions is determined based on the timing relationship value.

Abstract: The present application relates to synchronization signal transmission using multiple beams. In an example, a network node may support M beams covering M areas. However, only K<M beams may be used at any time for transmission of synchronization signals. Accordingly, the network node cycles through the K beams allocated to synchronization signal transmission, whereby a synchronization signal is transmitted on K spatially-multiplexed and simultaneously-active beams to reach K coverage areas during a first time period, then next K coverage areas during a second time period, and so on until all of the M coverage areas are reached to restart the cycle. A UE is located in only one coverage area, and would see the synchronization signal beam once during a period of time equal to the time needed to cycle through the M coverage areas.

Abstract: This disclosure is directed towards improved methods for identifying one or more base stations for connection with user equipment. The user equipment may establish a connection with a base stations based on an estimated location of the base station. Additionally, the user equipment may receive an indication from the base station to scan for additional base stations at additional estimated locations. Further, the user equipment may determine one or more connection parameters (e.g., distance from communication hub to user equipment, angle of communication hub relative to user equipment, shadowing at the communication hub, and the like) associated with the base stations within the geographical area. The user equipment may establish connection with base stations that are determined to have the best signal strength based on the connection parameters.

Abstract: A system of optimizing communications of a plurality of wireless mobile units over a ground coverage area includes a plurality of airborne wireless base stations each fixed over a designated portion of the ground coverage area. Each base station can be raised or lowered in in accordance with communications needs of the wireless mobile units registered with each base station. Each base station has at least one antenna that provides a coverage cone below the wireless base station and results in the designated coverage area having a ground size dependent upon altitude. A controller is adapted to receive parameters relating to the communications between the wireless mobile units and the wireless base stations and to determine a desired altitude for each of the wireless base stations to optimize the communications.
