Additional reference signals for UEs in non-connected states

A method, performed by a network node in a wireless network, for transmitting reference signals (RS) to one or more user equipment (UEs), the method comprising:

• transmitting, to one or more UEs, a configuration for RS, wherein the RS are periodic channel state information RS (CSI-RS) or periodic tracking RS (TRS);
• while the one or more UEs are in the non-connected state, transmitting paging downlink control information (DCI) during a paging occasion for the one or more UEs, wherein the paging DCI includes a field that indicates the configuration is activated;
• and
• while the one or more UEs are in the non-connected state, transmitting the RS during one or more first occasions associated with the configuration.

A user equipment (UE) configured to receive reference signals (RS) in a wireless network, the UE comprising:

• radio transceiver circuitry configured to communicate with a network node in the wireless network;
• and
• processing circuitry operatively coupled to the radio transceiver circuitry, whereby the processing circuitry and the radio transceiver circuitry are configured to:
• receive, from the network node, 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, determine that the connected-state RS are available during one or more first occasions, wherein the determination 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 receive the RS during the first occasions.
