Techniques for managing handovers in an unlicensed radio frequency spectrum band

A method for wireless communications, comprising:

• receiving, at a user equipment (UE), from at least one of a non-serving base station or a non-serving wireless local area network (WLAN) access point (AP), a signal on an unlicensed radio frequency spectrum band, wherein the non-serving base station or the non-serving WLAN AP is outside of a first energy detection range of a first base station;
• measuring one or more parameters associated with the signal;
• generating a UE measurement report that indicates that the non-serving base station or the non-serving WLAN AP is a source of interference at the UE based at least in part on receiving the signal;
• transmitting the UE measurement report to the first base station, the UE measurement report based at least in part on the one or more measured parameters;
• and
• receiving, from the first base station, a handover command to initiate communications with a second base station based at least in part on the UE measurement report, wherein the non-serving base station or the non-serving WLAN AP are within a second energy detection range of the second base station.

An apparatus for wireless communications at a first base station, comprising:

• a processor,
• memory coupled to the processor;
• and
• the processor and memory configured to:
• receive, at the first base station, a plurality of base station measurement reports, each of the plurality of base station measurement reports received from one of a plurality of base stations, the plurality of base station measurement reports including information associated with one or more first devices that transmits first signals using an unlicensed radio frequency spectrum band, and the one or more first devices different from the plurality of base stations;
• receive, at the first base station, a user equipment (UE) measurement report from a UE, the UE measurement report including information associated with one or more second devices that transmits second signals on the unlicensed radio frequency spectrum band, the one or more second devices different from the UE, and the one or more first devices or the one or more second devices are out of a first energy detection range of the first base station;
• determine whether to handover the UE to a second base station based at least in part on receiving the plurality of base station measurement reports including the information associated with the one or more first devices and receiving the UE measurement report, wherein the one or more first devices is different from the plurality of base stations and different from the UE and wherein the one or more first devices or the one or more second devices are within a second energy detection range of the second base station;
• and
• transmit, from the first base station, a handover command based at least in part on a determination to handover the UE to the second base station.
