Abstract
A node in a wireless system using transmit/receive slots for a communication among the nodes in the wireless system comprises a reception block configured to receive from a transmitting node in the wireless system a synchronization signal, and to derive from the synchronization signal a time offset and a frequency offset between the clock generators in the node and in the transmitting node. Further, a slot synchronization block is provided including the clock generator which is updated based on the derived time offset and the derived frequency offset. Further, a transmission block is provided for transmitting data. The slot synchronization block sets a slot start of a slot based on the derived time offset and sets a slot of a subsequent slot based on the derived frequency offset.
