1. A method, performed by a user equipment (UE), for receiving reference signals (RS) in a wireless network, the method comprising:
receiving, from a network node in the wireless network, a configuration for RS, wherein the RS are periodic channel state information RS (CSI-RS) or periodic tracking RS (TRS);
while the UE is in a non-connected state, determining that the RS are available during one or more first occasions, wherein the determining is based on the received configuration and on a field in paging downlink control information (DCI) detected by the UE during a paging occasion while in the non-connected state, wherein the field indicates that the configuration is activated; and
while the UE is in the non-connected state, selectively receiving the RS during the first occasions.
