Presentation Transcript

  1. Open issues impacting RAN2and/or RAN4 • Possible network assistance regarding DRS timing configuration • allowed measurement bandwidth • periodicity • duration • Possible network assistance regarding DRS occasion configuration • CSI-RS configuration • List of candidate cells/TPs information • MBSFN, TDD DL/UL configuration • Measurement gap • UE measurement behavior in cell on/off, DRX, activated/deactivated SCell • RSSI definition and RSRQ definition/support

  2. Open issues mainly for RAN1 • Whether a UE can be configured with both legacy-based measurement and DRS-based measurement • Relation between DMTC, measurements gap, DRX • DRS burst design • QCL • Restricted measurement set handling • Multiplexing of DRS with other signals such as PDSCH, feedback CSI-RS
