Mueller Exhibit 32 3GPP TSG RAN WG1/WG2 Joint Meeting on HSDPA Sophia Antipolis, FR April 5-6, 2001 Agendaltem: Source: Title: 12A010044 4 Samsung Electronics Co. Enhanced Symbol Mapping method for the modulation of Turbocoded bits based on bit priority Document for: Discussion and approval 1. Introduction This contribution proposes enhanced symbol mapping method for the modulation of Turbo-coded bits based on bit priority in HSDPA channel structure. The output of Turbo encoder consists of systematic (S) bits and parity (P) bits and it is well known that S bits have higher priority than P bits for the decoder performance. In HSDPA, high order modulations, e.g., 16QAM, 64QAM, are used, whose symbol consists of bits with different reliability. Then it is expected that the overall system performance would be improved if higher priority bits have higher reliability. Based on this idea, this contribution suggests an enhanced symbol mapping method, where S bits are mapped to high reliability bits and P bits to low reliability bits for modulation. The performance gain of the proposed method is evaluated by simulations for 16QAM and 64 QAM. 2. Current HSDPA channel structure Figure 1 shows the current HSDPA channel structure [1]. i/ Transfort B bcks Rate M atchhg In ter bave ~ Figure 1 Current HSDPA channel structure APLNDC-WH-A 0000011411 The interleaver mixes the output S bits and P bits of turbo encoder randomly before the symbol mapping for modulation. Thus, S bits and/or P bits are assigned to symbols without considering their priorities. 3. Proposed structure P ~ M odu hbr Figure 2 proposed HSDPA channel structure Figure 2 shows the proposed structure where the original interleaver is replaced by two independent interleavers under the control of AMCS. The idea of separating S bits from P bits was proposed in [2] for HARQ combining but, in [2],_no symbol includes S and P bits simultaneously, while a symbol for the proposed method includes S and P bits simultaneously according to the mapping rule. P/S (Parallel to Serial) block maps the output of the interleavers to high (H) and low (L) priority parts as shown in figure 3 for 3.33ms TTI, where S and P bits are placed on H and L part respectively. One Symbol Length 3.33 ms H : High priority L : Low- priority Figure 3 Parallel-to-Serial output APLNDC-WH-A 0000011412 Every symbol includes S part and In part and the size of two parts could be different according to the coding rate. Figure 4 shows how to map the P/S output to a symbol.

Simulation results The proposed method is compared with the conventional method under the following simulation parameters. ¯ Code block size: 2304bits/3.33ms ¯ Coding rate: 0.5 (S and P parts are symmetric) ¯ Modulation: 160AM and 640AM ¯ Carrier Frequency: 2GHz ¯ Channel: AWGN and single path fading with speed 60km ¯ HARQ: off For AWGN channel, referring to figure 5-6, about 0.3dB-0.7dB gain is achieved and the gain of 640AM is better than that of 160AM. Since the gain difference between high and low reliability bits is bigger for 640AM than 160AM, proposed method is more efficient for 640AM. Also, in figure 7-8, the gain ldB-2.SdB for fading is bigger than AWGN since separated interleaver gain may be added, i.e., independently interleaved APLNDC-WH-A 0000011413 bits are diffused to inherent place in symbols and it may has an effect as extra interleaving. 5. Conclusion An enhanced symbol mapping method is proposed for the modulation of Turbo coded bits based on bit priority. Simulation results show that the BER performance improves considerably by employing the proposed method. Therefore, it is suggested that the proposed method be considered for HSDPA and included in RAN WG1 technical report. 6. ]~eference [1] R1-01-0430, 3G TR25.848 v0.6.0 "Physical Layer Aspects of UTRA High Speed Downlink Packet AccessL [2] R1-01-0206, "Text p[oposal fo[ HARO complexity evaluation section of 1R25.848" Panasonic.
