Way forward to NB-IoT 3GPP TSG RAN WG1 #83 R1-157xxx Anaheim, USA, 15th-22th November 2015 Way forward to NB-IoT CMCC, Vodafone, Ericsson, Huawei, Hisilicon, Deutsche Telekom, Mediatek, Qualcomm, Nokia Networks, Samsung, Intel, Nuel, CATR, AT&T, NTT DOCOMO, ZTE, Telecom Italia, IITH, CEWiT, Reliance-Jio, CATT, u-blox, China Unicom, LG Electronics, Panasonic, Alcatel-Lucent, Alcatel-Lucent Shanghai Bell, [China Telecom], [Verizon]

Proposal on NB-IoT uplink Single-tone transmissions are supported 2 numerologies should be configurable for Single-tone transmission: [3.75]kHz and 15kHz A cyclic prefix is inserted Frequency domain Sinc pulse shaping in the physical layer description Multi-tone transmissions are supported Multi-tone transmissions are based on SC-FDMA 15 kHz UL subcarrier spacing Additional mechanisms for PAPR reduction FFS The UE shall indicate the support of Single-tone and/or Multi-tone Details to be discussed by WGs

Proposal on NB-IoT downlink Downlink transmission with 15kHz subcarrier spacing for all the scenarios: standalone, guardband, in-band
