Abstract
Technology is provided for supporting different numerologies for concurrent intra-frequency measurements and downlink data reception. A user equipment (UE) may send a message to the a wireless network to indicate 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). Based on the indication, the network may configure 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.
