SECONDARY SYNCHRONIZATION CODEBOOK FOR E-UTRAN

摘要

Providing for secondary synchronization encoding utilizing a primary synchronization channel (P-SCH)-related scrambling code is described herein. Scrambled secondary synchronization codes (SSCs) can be assigned to multiple base stations of a radio access network (RAN). By way of example, PSC-based scrambling codes can be created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating SSCs. Selection can be based on transmission characteristics of resulting SSCs, providing reduced interference in planned, semi-planned and/or unplanned mobile deployments.

主权项

1. An apparatus for mitigating synchronization code interference in a wireless communication system, comprising:
a processor configured to:
select a pair of sequences;generate scrambling codes;scramble the pair of sequences using the scrambling codes, thereby providing a scrambled pair of sequences; andinterleave the scrambled pair of sequences to form a secondary synchronization code (SSC); and a memory coupled to the processor.
