Mapping schemes for secondary synchronization signal scrambling

摘要

Embodiments of the present disclosure provide a transmitter, a receiver and methods of operating a transmitter and a receiver. In one embodiment, the transmitter includes a synchronization unit configured to provide a primary synchronization signal and a secondary synchronization signal having first and second segments. The transmitter also includes a secondary scrambling unit configured to provide a scrambled secondary synchronization signal, wherein scrambling agents for the first and second segments are derived from a primary synchronization sequence of the primary synchronization signal. The secondary scrambling unit is further configured to provide an additional scrambling of one of the first and second segments, wherein a second scrambling agent is derived from the remaining segment of a secondary synchronization sequence of the secondary synchronization signal. The transmitter further includes a transmit unit configured to transmit the primary synchronization signal and the scrambled secondary synchronization signal.

主权项

1. A receiver, comprising:
a receive unit configured to receive a primary synchronization signal and a scrambled secondary synchronization signal having at least two segments; a synchronization unit configured to detect the primary synchronization signal, the synchronization unit further configured to detect the scrambled secondary synchronization signal wherein the scrambling of the scrambled secondary synchronization signal is derived from a primary synchronization sequence of the primary synchronization signal, the receiver further configured to use the scrambled secondary synchronization signal to connect to a cellular network and to prepare for handover to a neighboring cell of the cellular network.
