Channel state information measurement adaptation to maximum multiple-input multiple-output layers

A user equipment (UE) configured for wireless communications, comprising:

• a memory comprising computer-executable instructions;
• and
• a processor configured to execute the computer-executable instructions and cause the UE to:
• change, based on an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive, from a first number of available channel state information (CSI) reference signal (CSI-RS) processing units (CPUs) of the UE to a second number of available CPUs of the UE;
• and
• send, to a network entity, an indication that the UE has changed to the second number of available CPUs.

A network entity configured for wireless communications, comprising:

• a memory comprising computer-executable instructions;
• and
• a processor configured to execute the computer-executable instructions and cause the network entity to:
• transmit, to a user equipment (UE), an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive;
• and
• receive, from the UE, an indication that the UE has changed from a first number of available channel state information (CSI) reference signal (CSI-RS) processing units (CPUs) of the UE to a second number of available CPUs of the UE.
