11-15-0584-00-00ax-considerations-on-ltf-sequence-design Sungho Moon (Newracom) presented 15/0584r0. Discussions: None SP1 (r1): Do you agree the following sentence to be adopted in SFD? 3.y.z. A STA transmit HE LTF only in the allocated subbands in UL OFDMA. Discussion: Hongyuan: the logic behind the proposal is too obvious to write into SFD. Robert: clarify that the allocated subbands are subbands allocated for the STA. The presenter decided to skip the SP SP2: Do you agree the following sentences to be adopted in SFD? 3.y.z. A HE LTF sequence for 40, 80, and 160MHz shall be made from concatenations of the HE LTF sequence for 20MHz with phase rotations and filling of missing tones. Detailed phase rotations and filling of missing tones are TBD. Discussion: Ron (BCM): is 8 the baseline of the SP? Sungho: Yes. Bin: is the concatenation referring to frequency domain concatenations or time domain concatenations? Sungho: Frequency domain. LG: is it for DL or UL and OFDMA case? Sungho: it’s for both DL and UL, and OFDMA. SP Result: 26Y/16N/36A SP3: Do you agree the following sentences to be adopted in SFD? 3.y.z. A HE 2xLTF shall reuse the 4xLTF sequence defined for the half-sized subband TBD for 2xLTF sequences for the smallest subband and the center band Note: and 4xLTF stand for HE LTFs which have symbol durations of 6.4us and 12.8 µs, respectively, excluding GI Discussion: None SP Result: 26Y/22N/23A
