Multi-cell periodic/SPS CSI reporting for wireless network

An apparatus, comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code,
• the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
• receive from at least one base station, at least two Channel State Information (CSI) reporting configurations for at least one of periodic and semi-persistent CSI reporting;
• determine at least two CSI reports are to be reported for the at least two CSI reporting configurations in a slot;
• determine whether Physical Uplink Control Channel (PUCCH) resources for the at least two CSI reporting configurations are overlapping in time on a carrier;
• rank the at least two CSI reports associated with the at least two CSI reporting configurations in a priority order in response to a determination that at least two PUCCH resources associated with the at least two CSI reporting configurations overlap in time at least partially;
• determine a number of multi-CSI reporting configurations, received by the apparatus, that are valid for a given slot;
• and
• make a decision to report at least one of the at least two CSI reports based on the number of valid multi-CSI reporting configurations.

A computer program product comprising a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:

• receiving from at least one base station, at least two Channel State Information (CSI) reporting configurations for at least one of periodic and semi-persistent CSI reporting;
• determining at least two CSI reports are to be reported for the at least two CSI reporting configurations in a slot;
• determining whether Physical Uplink Control Channel (PUCCH) resources for the at least two CSI reporting configurations are overlapping in time on a carrier;
• and
• ranking the at least two CSI reports associated with the at least two CSI reporting configurations in a priority order in response to a determination that at least two PUCCH resources associated with the at least two CSI reporting configurations overlap in time at least partially;
• determining a number of multi-CSI reporting configurations that are valid for a given slot;
• and
• making a decision to report at least one of the at least two CSI reports based on the number of valid multi-CSI reporting configurations.
