Introduction In current SDD draft (IEEE C802.16m-08/003r6), antenna configuration of (8, 8) is specified, and 8-stream transmission is supported. Currently, two pilot patterns have been proposed in previous IEEE session, IEEE C802.16m-08_1426r1 and IEEE C802.16m-08_1461. The link level performance comparison is carried out in this contribution to show the superiority of our pilot pattern.

Pilot patterns comparison Fig. 2 Pilot structure in C802.16m-08_1461.doc Fig. 1 Fujitsu’s pilot structure Pilot density = 22.2% Pilot density = 29.6%

Simulation settings Antenna configuration 8x8 Antenna correlation Un-correlated Pilot pattern C802.16m-08_1426r1.doc (Pilot density = 22.2%) Pilot in C802.16m-08_1461.doc (Pilot density = 29.6%) Channel model ITU PB 3km/h & VA 30km/h Channel estimation MMSE MCS levels 16e MCS set (QPSK 1/2 with rep 1,2,4,6, QPSK 3/4,16QAM 1/2, 3/4, 64QAM 1/2, 2/3, 3/4, 5/6) Coding CTC Equalization Performance metric MSE, BLER, Single-link throughput

Channel estimation performance We take PB3, VA30 channels as two examples to show the effect of pilot structure on channel estimation.

BLER performance under PB 3km/h channel Ideal  ideal channel Fujitsu  with channel estimation using Fujitsu’s pilot C802.16m-8_1461.doc  with channel estimation using Fujitsu’s pilot In this figure, we just compare three MCS levels to show the effects of channel estimation on the BLER performance based on a given pilot structure. For other MCS levels, the results is similar to this figure.

BLER performance under VA 30km/h channel Ideal  ideal channel Fujitsu  with channel estimation using Fujitsu’s pilot C802.16m-8_1461.doc  with channel estimation using Fujitsu’s pilot

Throughput comparison under PB 3km/h channel

Throughput comparison under VA 30km/h channel The smaller number of pilot, the higher throughput. For our pilot scheme, the degradation of channel estimation from low pilot density can be omitted while throughput enhancement is obvious.

Conclusion The pilot density of Fujitsu’ scheme is lower than that in C802.16m-08_1461.doc. However, the two scheme have almost the same BLER performance, especially in practical SNR region, [0, 30dB]. The single-link throughput performance from Fujitsu’s pilot is better than that from C802.16m-08_1461.doc, and all they perform better than 4-stream case due to spatial multiplexing gain. The pilot pattern we proposed is more efficient for 8-stream transmission at practical SNR levels.

Text proposal To adopt the following figure as 8-stream pilot pattern. In line 7 of page 80, insert the following figure , Fig. xx Pilot Pattern C for 8 stream pilots, pilot k denotes pilot for transmit antenna k.
