Publication number: 20240155696Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement(s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.Type: ApplicationFiled: August 5, 2021Publication date: May 9, 2024Inventors: Jie Cui, Fangli Xu, Yushu Zhang, Yang Tang, Qiming Li, Manasa Raghavan, Xiang Chen, Huaning Niu, Hong He, Dawei Zhang
