Rel-17 work builds on earlier studies performed in Rel-15 and Rel-16, where NTN channel models and necessary adaptations of the NR technology to support NTN were identified. The main challenges identified in Rel-16 and addressed in Rel-17 are related to the mobility and orbital height ...
针对此问题,3GPP NTN Release 17在新增SIB19广播消息中下发小区级偏移量(Cell-specificK_offset),用于调整初始接入过程中的上下行交互定时关系,解决大尺度传播时延带来的数据传输时序问题。通常情况下,小区级偏移量为满足小区内所有用户初始接入所需时序偏移量的最大值,为满足终端性能要求,3GPP NTN Release 17也支持RR...
