User equipment and base station for frame timing and cell group synchronization


Abstract

Methods and systems for receiving a primary and secondary synchronization signal from a cell are provided. The secondary synchronization signal may be derived from at least one of a set of sequences and received based on the timing of the received primary synchronization signal. Determining a time slot within a frame of the received secondary synchronization signal and a group of the cell is provided, wherein the time slot and the group are determined by at least one sequence of the secondary synchronization signal and at least one carrier out of a plurality of carriers used for one sequence out of the at least one sequence of the secondary synchronization signal. Determining a frame timing and a sequence used by the cell, based on the received primary synchronization signal and the secondary synchronization signal is further provided.
