In an aspect, different scrambling sequences for different channels and signals may be generated based on different cyclic shifts of a base scrambling sequence, which may be a maximal-length sequence. A scrambling sequence for a given channel may be generated by (i) determining a sequence selector value based on a channel type value and at least one parameter value for the channel and (ii) cyclically shifting the base scrambling sequence based on the sequence selector value. In another aspect, a reference signal sent on variable system bandwidth may be generated with two scrambling sequences, which may be different cyclic shifts of a base scrambling sequence. Scrambling/descrambling for positive and negative frequencies for the reference signal may be performed with the first and second scrambling sequences, respectively."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scrambling sequence generation in a communication system","description":"Techniques for performing scrambling and descrambling in a communication system are described.
