Enhanced channel state information derivation

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform:
• receiving, from a network, a channel state information report configuration comprising multiple sub-configurations;
• determining a reference for a power control factor;
• determining based at least in part on the reference for the power control factor, the power control factor for a sub-configuration of the multiple sub-configurations;
• and
• transmitting, to the network, a channel state information report associated with the sub-configuration, wherein the channel state information report comprises one or more channel state information quantities, and at least one of the one or more channel state information quantities is determined based on the power control factor for the sub-configuration.

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform:
• sending, to a user equipment, a channel state information report configuration comprising multiple sub-configurations;
• receiving a channel state information report associated with a sub-configuration of the multiple sub-configurations, wherein the channel state information report comprises one or more channel state information quantities determined based on a power control factor for the sub-configuration;
• and
• determining a spatial pattern based on the received channel state information report.

A method, comprising:

• receiving, at a user equipment from a network, a channel state information report configuration comprising multiple sub-configurations;
• determining, by the user equipment, a reference for a power control factor;
• determining, by the user equipment, based at least in part on the reference for the power control factor, the power control factor for a sub-configuration of the multiple sub-configurations;
• and
• transmitting, by the user equipment to the network, a channel state information report associated with the sub-configuration, wherein the channel state information report comprises one or more channel state information quantities, and at least one of the one or more channel state information quantities is determined based on the power control factor for the sub-configuration.
