    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: 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.
