WebWhat are uplink and downlink? The communication going from a satellite to ground is called downlink, and when it is going from ground to a satellite it is called uplink. When an uplink is being received by the spacecraft at the same time a downlink is being received by Earth, the communication is called two-way. WebJul 30, 2024 · In order to assess the characteristics of the network, there are two things we want to measure: the time it takes for a message to be received by a satellite and the time it takes to be downlinked to a ground station and made available in the Hive. time to uplink + time to downlink and deliver = total time Measuring these is a bit tricky.
WebApplying this terms to synchronization process, we have two types of synchronization in cellular communication including 5G/NR called 'Downlink Synchronization' and 'Uplink … WebThe normalized time offset can be calculated as , 2 mi T N m φ τ π = (9) The actual time offset is given by ,, 22 mi mi T NT T mm φφ ττ ππ == = Δ (10) where Δ represents the interspacing between each two neighboring SC-FDMA sub-carriers in the frequency domain.

WebEach subframe consists of two equally sized slots. For FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each radio frame. Uplink and downlink transmissions are separated in the frequency-domain. The transmission time interval in the downlink and uplink is 1 ms [107]. http://www.qrg.northwestern.edu/projects/vss/docs/Communications/1-what-are-uplink-and-downlink.html
