Claim 0:
1. A method for provisioning radio resources for Idle or Inactive mode UEs in wireless network, the method comprising
configuring by a network node for idle or Inactive mode of a UE:
a plurality of reference signals comprising of:
reuse of at least one of Connected mode reference signal including at least one of:
Non-Zero Power Channel State indicator Reference Signal (NZP CSI-RS) resource
Tracking Reference Signal (TRS) resource
Phase Tracking Reference Signal (PTRS) resource
a new reference signal including at least one of:
NZP CSI-RS resource
TRS resource
PTRS resource
new Demodulation Reference Signal (DMRS) and enabling the UE based on at least one of the reference signal from the configured plurality of reference signals for performing one or more of:
at least one of gain, time, phase, and frequency synchronization;
Radio Resource Management (RRM) measurements; and
Quasi-Co-Location (QCL) assumption for Paging PDCCH decoding, wherein the configuration of reference signal resource is performed as at least one of:

placing new configuration within existing broadcast message such as SIB1 or other SIB or newly introduced broadcast message such a new SIB in the Idle/Inactive mode;
configuring UEs in the Connected mode by RRC signaling such as an RRC reconfiguration message based on configuration changes pertinent to common reference signal resources; and
configuring UEs by at least one of RRC Release, RRC Release with Suspend Config and RRC Release with Redirection message when moving UE to Idle or Inactive mode from Connected mode.
