INTERFERENCE CLASSIFICATION-BASED CARRIER SENSE ADAPTIVE TRANSMISSION (CSAT) IN UNLICENSED SPECTRUM
First Claim
1. A method of Carrier Sense Adaptive Transmission (CSAT) for reducing interference between Radio Access Technologies (RATs), comprising:
- receiving signals via a resource, wherein a first RAT is used to receive the signals;
classifying interference on the resource associated with the first RAT, wherein the interference classification is based on the received signals;
setting one or more cycling parameters of a Time Division Multiplexing (TDM) communication pattern defining activated and deactivated periods of transmission for a second RAT sharing the resource, wherein the setting is based on the interference classification; and
cycling operation of the second RAT between activated and deactivated periods of transmission over the resource in accordance with the TDM communication pattern.

Abstract
Systems and methods for Carrier Sense Adaptive Transmission (CSAT) for reducing interference between Radio Access Technologies (RATs) in unlicensed spectrum are disclosed. A small cell base station may receive signals via a resource, wherein a first RAT is used to receive the signals, and classify interference on the resource associated with the first RAT based on the received signals. Based on the interference classification, one or more cycling parameters may be set for a Time Division Multiplexing (TDM) communication pattern defining activated and deactivated periods of transmission for a second RAT sharing the resource, and operation of the second RAT may be cycled between activated and deactivated periods of transmission over the resource in accordance with the TDM communication pattern.
