Channel state information (CSI) reporting for frequency hopping in unlicensed frequency bands

A wireless communication device, comprising:

• an interface configured to:
• obtain a signal indicating a frequency hopping pattern, the frequency hopping pattern indicating an ordering of a plurality of hopping channels associated with the frequency hopping pattern;
• obtain an indication of a plurality of groups, each group of the plurality of groups comprising one or more hopping channels of the plurality of hopping channels, the one or more hopping channels being grouped such that a combined bandwidth part (BWP) hopping frequency of the one or more hopping channels spans a continuous frequency range;
• and
• obtain a channel state information reference signal (CSI-RS) via a hopping channel of the plurality of hopping channels according to the ordering;
• a processing system configured to:
• determine channel state information (CSI) of the hopping channel based on the CSI-RS;
• and
• the interface is further configured to:
• output the CSI of the hopping channel for transmission to a network node.

A method for wireless communication performed by an apparatus of a network node, comprising:
