1. A method implemented in a wireless device, WD, the method comprising:
receiving a Channel State Information-Reference Signal, CSI-RS, (CSI-RS) resource configuration for one CSI-RS resource;
receiving a CSI report configuration, the receiving of the CSI report configuration comprising receiving a time domain restriction for channel measurement configuration, the CSI-RS resource configuration and the CSI report configuration mapping each of a plurality of time-domain beam sweeping CSI-RS transmissions in the configured one CSI-RS resource to a corresponding CSI report;
receiving at least one of the plurality of time-domain beam sweeping CSI-RS transmissions in the configured one CSI-RS resource;
transmitting at least one CSI report according to the mapping; and
as a result of the time domain restriction for channel measurement configuration, performing a channel measurement for the at least one CSI report, the channel measurement based on a most recently received one of the plurality of time-domain beam sweeping CSI-RS transmissions, the most recently received one of the plurality of time-domain beam sweeping CSI-RS transmissions being no later than the CSI reference resource and being associated with the at least one CSI report.
