CARRIER SENSE ADAPTIVE TRANSMISSION (CSAT) COORDINATION 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;
identifying utilization of the resource associated with the first RAT, wherein the identification is based on the received signals;
cycling operation of a second RAT between activated and deactivated periods of transmission over the resource in accordance with a Time Division Multiplexing (TDM) communication pattern, wherein the cycling is based on the identified utilization of the resource; and
transmitting an Activation/Deactivation Medium Access Control (MAC) Control Element (CE) to a user device associated with the second RAT to activate or deactivate the user device in accordance with the TDM communication pattern.

Abstract
Systems and methods for Carrier Sense Adaptive Transmission (CSAT) communication in unlicensed spectrum are disclosed. Interference between Radio Access Technologies (RATs) may be reduced utilizing CSAT by, for example: receiving signals via a resource, wherein a first RAT is used to receive the signals; identifying utilization of the resource associated with the first RAT, wherein the identification is based on the received signals; cycling operation of a second RAT between activated and deactivated periods of transmission over the resource in accordance with a Time Division Multiplexing (TDM) communication pattern, wherein the cycling is based on the identified utilization of the resource; and transmitting an Activation/Deactivation Medium Access Control (MAC) Control Element (CE) to a user device associated with the second RAT to activate or deactivate the user device in accordance with the TDM communication pattern.
