1. A method for a wireless network, the method comprising:
decoding a message from a user equipment (UE), the message comprising an indication of whether the UE supports a mixed numerology wherein a different subcarrier spacing (SCS) is used in a serving cell or a neighboring cell for concurrent processing of at least two of:
intra-frequency measurement by the UE of a synchronization signal block (SSB);
intra-frequency measurement by the UE of a channel state information reference signal (CSI-RS) for mobility; and
reception by the UE of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH);
wherein the indication indicates whether the UE supports concurrent intra-frequency measurement on the serving cell or the neighboring cell for both the SSB with a first SCS and the CSI-RS for mobility with a second SCS;
based on the indication, configuring at least one of a CSI-RS measurement expectation, an SSB measurement expectation, and a scheduling restriction for reception of the PDCCH or the PDSCH by the UE;
based on the indication, configuring at least one of the CSI-RS and the PDCCH or PDSCH; and
responsive to the indication indicating that the UE does not support the mixed numerology, using a scaling factor to divide time resource allocation between CSI-RS based mobility measurement and SSB based mobility measurement.
