Abstract: Aspects for reducing interference between networks are provided, in particular in the context of mobile communications LAA-LTE use of unlicensed spectrum in use by WiFi devices. A signal transmitted by multiple devices in a first network over a communications medium using the unlicensed frequency spectrum is decoded to determine one or more parameters of a packet in the signal, in particular type of the packet and trasnmitter identity. A level of utilization of the communications medium by the multiple devices in the first network is estimated based at least in part on a signal strength of the signal and the one or more parameters. A variable period of time for communicating in a second network over the communications medium using the unlicensed frequency spectrum is then adjusted based on the estimated level of utilization of the communications medium by the first network. In addition, a number of active transmitters over the communications medium can be determined based on identifying the transmitting source and adjusting the time for communicating in the second network can be further based on the number of active transmitters.

Abstract: Systems and methods for Discontinuous Reception (DRX)-aware Carrier Sense Adaptive Transmission (CSAT) communication in shared spectrum are disclosed. An access point, for example, may receive signals via a medium in accordance with a first RAT, and identify utilization of the medium associated with the first RAT based on the received signals. Based on the identified utilization of the medium, operation of a second RAT may be cycled between activated and deactivated periods of transmission over the medium in accordance with a Time Division Multiplexing (TDM) communication pattern. A Medium Access Control (MAC) Control Element (CE) may be transmitted to an access terminal associated with the second RAT to activate or deactivate the access terminal in accordance with the TDM communication pattern. The timing of the MAC CE transmission may be based on the TDM communication pattern and a DRX pattern associated with the access terminal.
