4 Rx diversity at eNBs yields moderate to substantial site coverage improvements. Likewise 4x2 at UE yields improvements for all devices regardless of 4x4 MIMO compatibility.

I understand the benefits of higher-order MIMO and receive diversity (and I am aware Sprint is focusing on 4xRx diversity for 800 MHz). What I do not understand is how the setup in the linked permit would achieve that without a C2PC on the RRH and something to tie them together.

I don't see anything in the actual permits to hint at higher-order MIMO for 800 MHz. I do see mention of (and support for) a second 800 LTE carrier. Taking occupied bandwidth into consideration, Sprint should have enough spectrum in most markets to do two 3x3 LTE carriers + 1 CDMA carrier in 800 MHz (as opposed to one 5x5 LTE + 1 CDMA carrier). That makes a lot more sense to me than trying to get 4x4 MIMO into tablets.

Ericsson has already been doing these in New Orleans with 2x RRUS 11 B26A.
