Non-integer multiple quantities of transmit and receive antenna subarrays

A second network node for wireless communication, comprising:

• a memory;
• a second circular antenna array comprising a second quantity of antenna subarrays, wherein each antenna subarray of the second circular antenna array comprises one or more antenna elements;
• and
• at least one processor coupled to the memory, wherein the at least one processor is configured to cause the second network node to:
• receive one or more reference signals from a first network node using the second circular antenna array;
• transmit, to the first network node based on the one or more reference signals, a feedback message that indicates a plurality of sets of beamforming weights or information for determining the plurality of sets of beamforming weights, wherein the plurality of sets of beamforming weights are based on a first circular antenna array at the first network node comprising a first quantity of antenna subarrays that is different than the second quantity of antenna subarrays included in the second circular antenna array;
• and
• receive one or more signals concurrently from the first network node using the second circular antenna array and based on the plurality of sets of beamforming weights, wherein each signal of the one or more signals is associated with a respective set of beamforming weights of the plurality of sets of beamforming weights.
