Abstract: User equipment performs autonomous time adjustment that includes selecting a Timing Error Limit (i.e. Te_NR) and Maximum Autonomous Time Adjustment Step (i.e. Tq_NR) based on bandwidth (BW) and subcarrier spacing (SCS). In one embodiment, given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=x/2(kHz) is 2*N. Given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=2*x(kHz) is N/2. For example, given BW=10 MHz, if the Te_NR of SCS=30k Hz is n*Ts_NR (TS_NR is the basic timing unit for NR system), then the Te_NR of SCS=60 kHz is N/2*Ts_NR, and the Te_NR of SCS=15 kHz is 2*N*Ts_NR.

Abstract: Techniques for improving CSI (Channel State Information) in connection with FD (Full Dimension)-MIMO (Multiple Input Multiple Output) are discussed. A first set of techniques can employ hierarchical cell common class B CSI-RS for improved beam selection. A second set of techniques can provide improved CSI feedback based on eigenvalue(s) and co-phase associated with a precoder. Various embodiments can employ either or both of the first set of techniques and/or the second set of techniques.
