Abstract
Methods and apparatuses are provided that include mitigating interference for devices communicating with femto nodes or other low power base stations by assigning protected resources for communicating therewith. The protected resources can be negotiated with a macrocell base station using interference cancellation. The protected resources can be assigned based on an early or late handover event, which can indicate that the device may be susceptible to interference from the macrocell base station.
Claims42
A method for mitigating interference in a wireless network, comprising:
- detecting a handover event related to a mobile device communicating with a base station;
- determining whether the handover event is one of an early handover event or a late handover event;
- and
- assigning a set of protected resources for communicating with the mobile device after the handover event, based on the handover event.
An apparatus for mitigating interference in a wireless network, comprising:
- means for detecting a handover event related to a mobile device communicating with a base station;
- and
- means for assigning a set of protected resources for communicating with the mobile device based on determining whether the handover event is one of an early hand over event or a late handover event.
An apparatus for mitigating interference in a wireless network, comprising:
- at least one processor configured to:
- detect a handover event related to a mobile device communicating with a base station;
- determine whether the handover event is one of an early handover event or a late handover event;
- and
- assign a set of protected resources for communicating with the mobile device after the handover event, based on the handover event;
- and
- a memory coupled to the at least one processor.
A computer program product for mitigating interference in a wireless network, comprising:
- a computer-readable medium, comprising:
- code for causing at least one computer to detect a handover event related to a mobile device communicating with a base station;
- code for causing the at least one computer to determine whether the handover event is one of an early handover event or a late handover event;
- and
- code for causing the at least one computer to assign a set of protected resources for communicating with the mobile device after the handover event, based on the handover event.
A method for mitigating interference in a wireless network, comprising:
- detecting a handover event related to handing over communications of a mobile device to a base station;
- and
- transmitting a handover message to the base station indicating whether the handover event corresponds to an early handover event.
