Abstract: Providing for sec-ondary 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 net-work (RAN). By way of example, PSC-based scrambling codes can be created from a plurality of M-se-quences generated from a common polynomial expression. Further, an SSC codebook is provided that se-lects sequence pairs of a sequence matrix for generating SSCs. Selec-tion can be based on transmission characteristics of resulting SSCs, providing reduced interference in planned, semi-planned and/or un-planned mobile deployments.

Abstract translation: 这里描述了利用主同步信道（P-SCH）相关的扰码提供辅助同步编码。 可以将加扰的辅助同步码（SSC）分配给无线电接入网络（RAN）的多个基站。 作为例子，可以从根据公共多项式表达式生成的多个M序列来创建基于PSC的扰码。 此外，提供了SSC码本，其选择用于生成SSC的序列矩阵的序列对。 选择可以基于生成的SSC的传输特性，在计划，半计划和/或计划外移动部署中提供减少的干扰。
