XDD: Cross Division Duplexing

Last updated on May 1, 2023

With XDD, we aim to improve system coverage and flexibility by allowing for sub-band full duplex. We implemented self-interference canncelation (SIC) to be able to cancel out the downlink interference so that a low SNR uplink could be recieved over more time slots then it would normally transmit.
