1. A method for uplink (UL) wireless backhaul communication at a wireless backhaul remote unit in a radio access network (RAN), comprising:
receiving a configuration for radio frames and a transmission schedule through a downlink (DL) physical-layer (PHY) broadcast channel, wherein each radio frame comprises a plurality of UL time slots and a plurality of DL time slots, and wherein the transmission schedule comprises a transmission allocation for the wireless backhaul remote unit;
generating a UL data frame, wherein generating the UL data frame comprises:
performing forward error correction (FEC) encoding on a data bit stream to generate a plurality of FEC codewords, wherein performing the FEC encoding comprises:
performing Reed Solomon (RS) encoding on the data bit stream to generate a plurality of RS codewords;
performing byte interleaving on the RS codewords; and
performing Turbo encoding on the byte interleaved RS codewords to generate one or more Turbo codewords, wherein each Turbo codeword is encoded from more than one RS codeword; and
performing frequency multiplexing to combine the UL data frame and a UL control frame across all symbols in a UL time slot; and
transmitting the UL data frame according to the transmission allocation.
