Which of the following RF modules support 64T64R?

The AAU5313 and RRU5901 do not support 64T64R. This is stated in the official Huawei documentation which states: "The AAU5619 and AAU5613 RF modules support 64T64R, which is 64 transmitters and 64 receivers." Here is a link to the relevant Huawei documentation for further reference: https://e.huawei.com/en/products/base-station/bbu5900/overview

64T64R (64 Transmit 64 Receive) is a high-density MIMO (multiple input multiple output) technology that uses multiple antennas at both the transmitter and receiver to improve the performance of the wireless communication system.
