8tx user equipment precoder codebook fallback

A network node for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• receive, from a user equipment (UE), capability information including:
• first capability information that indicates a minimum supported value, of a plurality of values, for a coherence parameter associated with a coherence level for a quantity of transmit (Tx) antennas of the UE, wherein each value, of the plurality of values, corresponds to a respective precoder codebook (CB) set, and
• second capability information that indicates one or more other values of the plurality of values, greater than the minimum supported value, for the coherence parameter that correspond to one or more supported fallback precoder CB sets for the quantity of Tx antennas;
• and
• transmit, to the UE, configuration information indicating a combination of one or more precoder CB sets, wherein the combination of one or more precoder CB sets is from one or more supported combinations of one or more precoder CB sets based at least in part on the first capability information and the second capability information.

A method of wireless communication performed by a user equipment (UE), comprising:

• transmitting, to a network node, capability information including:
• first capability information that indicates a minimum supported value, of a plurality of values, for a coherence parameter associated with a coherence level for a quantity of transmit (Tx) antennas of the UE, wherein each value, of the plurality of values, corresponds to a respective precoder codebook (CB) set, and
• second capability information that indicates one or more other values of the plurality of values, greater than the minimum supported value, for the coherence parameter that correspond to one or more supported fallback precoder CB sets for the quantity of Tx antennas;
• and
• receiving, from the network node, configuration information indicating a combination of one or more precoder CB sets, wherein the combination of one or more precoder CB sets is selected from one or more supported combinations of one or more precoder CB sets based at least in part on the first capability information and the second capability information.
