Abstract: Described herein are techniques for reducing interference to non-cellular communications on an unlicensed band by a network entity sending/receiving cellular communications on the unlicensed band. For example, the technique may involve operating in a first mode using a first radio access technology (RAT1), and collecting interference measurements for interference to or from at least one mobile device while in the first mode. The technique may also involve switching to a second mode and using a second radio access technology (RAT2), and using the interference measurements from the first mode to minimize interference caused or experienced by the network entity in the second mode.

Abstract: Methods and apparatus for adjusting transmission power in wireless networks are provided. One aspect of the disclosure provides a method of wireless communication over a wireless communication medium. The method includes determining a level of interference for a data transmission from a transmitting device to an intended receiving device. The method further includes setting a transmission power level for transmitting a message based on the interference level, the message comprising one of a request-to-send (RTS) packet and a clear-to-send (CTS) packet. The method further includes transmitting the message at the set transmission power level.

Abstract: Described herein are techniques for reducing efficient LTE operation in the unlicensed band. For example, the technique may involve establishing a connection with a primary component carrier on the licensed communication band or the unlicensed communication band. The technique may also involve determining at least one metric associated with a constraint on a transmissions channel of the unlicensed communication band. The technique may also involve sending the at least one metric to the primary component carrier. The technique may also involve receiving a message for one of switching on or switching off a secondary component carrier (SCC) for transmissions on the unlicensed communication band in response to sending the at least one metric.
