Patent ID: 11963141
Assignee: SUN PATENT TRUST
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. An integrated circuit comprising circuitry, which, in operation:
controls reception of a reference signal, the reference signal being based on a sequence that is initialized with a random seed Cinit generated by

cinit=(└ns/2┘+1)·(2ID+1)·216+SCID,

the random seed being one of a first random seed and a second random seed, the first random seed being generated using ID specific to a cell, and the second random seed being generated using ID dedicated to a communication apparatus,
wherein, ns is a slot number, SCID is 0 or 1, and the ID is determined based on the SCID; and
demodulates data based on the reference signal.
