5GNR Resource Grid的开发目前基于3GPP Rel-15(2018-03)规范文本。主要参考的标准文本有:38.104, 38.211/212/213/214,38.321,38.331。
5-25号完成以下需求分析:
(1)NR operating band和BW配置(refer to 38.104)
**FR1和FR2的定义,FR1为<6GHz,FR2为>6GHz

**FR1 and FR2 with its duplex mode(FDD/TDD/SUL/SDL)


**N_RB for FR1 and FR2 w.r.t. SCS (240KHz is not supported for PUSCH/PDSCH)

**N_RB per operating band per SCS
Table 5.3.5-1: BS channel bandwidths and SCS per operating band in FR1 <omitted>

**Channel spacing and channel raster shall have no impact
**Synchronization raster and GSCN shall have no impact
**SSB pattern w.r.t. SSB SCS(60KHz is not supported for SSB):
NR n38/n41 corresponding to LTE b38/b41
NR n50 1.5G?
NR n77/n78 3.5G, n79 4.5G


At least we need following parameters:
l nrOpBand: NR operating band excluding SUL and SDL
l nrScs: NR subcarrier spacing for PUSCH/PDSCH (240K not supported)
l TODO: for FDD, nrScs can be different between UL and DL?
l nrSsbScs: NR subcarrier spacing for SSB (60K not supported)
l nrBw: NR bandwidth
本文基于3GPP Rel-15规范,探讨了5G NR operating band及带宽配置,包括FR1和FR2频段定义及其双工模式(FDD/TDD/SUL/SDL),针对不同子载波间隔的RB数量,并详细说明了SSB模式及其对应参数。
