Tiered groups of devices (tiered service radios) and/or licenses associated with the devices or users so as to provide a hieratical set of interference protection mechanisms for members of each tier of service are disclosed. Point-to-point and point-to-multipoint data links for any communication application, including wireless backhaul applications, are also disclosed. Exemplary systems, devices, and methods disclosed herein allow for the efficient operation of such a tiered service. Interference protection among tiered service devices belonging to one or more tiers of the service, from other devices within the same tier of service, or devices of other tiers of service, is disclosed. Identification of other devices of the same or differing tiers of service, and interference mitigation between other tiered service devices based upon intercommunication between the devices, and/or via a central registry database, are also disclosed.

In a broadband wireless communication system, a spread spectrum signal is intentionally overlapped with an OFDM signal, in a time domain, a frequency domain, or both. The OFDM signal, which inherently has a high spectral efficiency, is used for carrying broadband data or control information. The spread spectrum signal, which is designed to have a high spread gain for overcoming severe interference, is used for facilitating system functions such as initial random access, channel probing, or short messaging. Methods and techniques are devised to ensure that the mutual interference between the overlapped signals is minimized to have insignificant impact on either signal and that both signals are detectable with expected performance by a receiver.

Certain aspects of the present disclosure provide techniques for interference mitigation. Certain aspects provide a method for wireless communication. The method generally includes performing communications, in a first channel, on a first downlink in a first time period based on communications in a second channel adjacent to the first channel being performed on a second downlink in the first time period. Communications in the first channel on a first uplink are performed in a second time period based on communication in the second channel being performed on a second uplink in the second time period. The method further includes refraining from communicating in the first channel on one or more resources in the first time period or the second time period to mitigate cross-link interference with a third channel adjacent to the first channel.
