NLOS wireless backhaul uplink communication

A wireless backhaul communication system comprising one or more processors;

• and a memory coupled to the one or more processors comprising instructions executable by the one or more processors to cause the one or more processors to:
• receive a first frame that includes a set of slots;
• detect a first slot that includes a synchronization sequence (SS) followed by a random access configuration;
• perform a random access procedure by transmitting a random access signal according to the random access configuration;
• receive a second frame in response to the random access procedure;
• and
• determine that the random access procedure is successful based on the second frame including a downlink (DL) time slot assignment for the wireless backhaul communication system.

A method comprising:

• receiving, by a first network device, a first frame that includes a plurality of slots;
• detecting, by the first network device, that a first slot of the plurality of slots includes a synchronization sequence followed by a physical broadcast channel block that includes a set of configuration information;
• transmitting, by the first network device, a second frame to establish random access communication in response to the synchronization sequence and the set of configuration information;
• and
• receiving, by the first network device, a third frame in response to the second frame, wherein the third frame includes a downlink time slot assignment for the first network device.
