Introduction Motivation –Problems in preamble for e system Poor synchronization performance for cell-edge/segment-edge users Sensitive to Doppler spread due to high mobility –Preamble structure to resolve problems with low overhead is desirable Purpose and Summary –Propose to be discussed and included in m SDD –A new preamble structure is proposed for robust synchronization

Design Considerations Low overhead Improved synchronization performance for cell/segment-edge users Robustness to Doppler spread induced by high mobility –Preamble structure which is robust to large Doppler spread is desired so as to keep MS synchronized with BS to maintain network connection under high-mobility environment (up to 350 km/hr) Fast temporal-domain preamble detection –Fast temporal domain preamble detection without decoding preamble code sequence can largely decrease the number of failure trials and thus speed up the synchronization process

Temporal-Domain Illustration of Proposed Preamble Structure

Frequency-Domain Illustration of Proposed Preamble Structure

Detail Design of Proposed Preamble Structure One OFDM symbol is used for new preamble –Total length: N + CP length The OFDM symbol is divided into two parts: –First preamble Along the time domain, N/2 samples only, no CP is applied Along the frequency domain, N/2 sub-carriers over the whole bandwidth DC sub-carrier is a null tone –Second preamble Along the time domain, (N/2 + CP length) samples, CP is applied Along the frequency domain, N/2 sub-carriers over the whole bandwidth DC sub-carrier is a null tone

Detail Design of Proposed Preamble Structure First Preamble: –Interleaved by K 1 over sub-carriers –The number of K 1 is limited by the following condition K 1 ≦ N/(2*CP_length); K 1 ≦ 4, if CP_length=N/8 –The first duplicate in time domain functions as a CP Second Preamble: –Can be interleaved by K 2 or not interleaved –The number of K 2 depends on K 1 and frequency reuse factor

Arrangement of Preamble Code Sequences Separate structure –Code sequences applied to first and second preamble are two independent codewords –Code sequence used in first preamble are the same in all cells For amplifier gain training, coarse synchronization and synchronization parameters estimation –Code sequences used in second preamble are different between segments For fine synchronization, channel estimation and segment identification Joint structure –Code sequences applied to first and second preamble are two partitions of one codeword –The combined codeword from two partitions is used for amplifier gain training, synchronization, channel estimation and segment identification

Properties of Proposed Preamble Structure Synchronization performance enhancement for users at the cell edge due to the utilization of macro diversity Preamble collision avoidance between segments can be achieved by FDM/CDM The proposed structure can be applied to any existing code sequence such as PRBS, Zadoff-Chu sequence and QCCC Robust to Doppler spread induced by high mobility The same overhead as that in IEEE e system Periodical structure along the time domain enables fast temporal-domain preamble detection FFT/IFFT with size N can be reused for preamble decoding
