Abstract
Interference that occurs during wireless communication may be managed by hybrid time reuse. A method, apparatus amend medium of communication determines one or more time reuse patterns of respective one or more unplanned access points. A second time reuse pattern that is less interfering with the one or more time reuse patterns is selected. Signals are transmitted according to the second time reuse pattern from a second unplanned access point to an associated access terminal.
Claims20
A method of communication, comprising:
- measuring signals from a macro cell and one or more neighboring femto cells;
- identifying a hybrid automatic repeat request (HARQ) interlace that exhibits the least interference;
- identifying a subframe based on the identified HARQ interlace;
- determining one or more time reuse patterns of the one or more neighboring femto cells;
- selecting a second time reuse pattern that is less interfering with the one or more time reuse patterns;
- and
- transmitting signals according to the second time reuse pattern from a second femto cell to an associated user equipment.
An apparatus for communication, comprising:
- an interference controller configured to:
- measure signals from a macro cell and one or more neighboring femto cells,
- identify a hybrid automatic repeat request (HARQ) interlace that exhibits the least interference,
- identify a subframe based on the identified HARQ interlace,
- determine one or more time reuse patterns of the one or more neighboring femto cells, and
- select a second time reuse pattern that is less interfering with the one or more time reuse patterns;
- and
- a communication controller configured to transmit signals according to the second time
- reuse pattern from a second femto cell to an associated user equipment.
An apparatus for communication, comprising:
- means for measuring signals from a macro cell and one or more neighboring femto cells;
- means for identifying a hybrid automatic repeat request (HARQ) interlace that exhibits the least interference;
- means for identifying a subframe based on the identified HARQ interlace;
- means for determining one or more time reuse patterns of the one or more neighboring femto cells;
- means for selecting a second time reuse pattern that is less interfering with the one or more time reuse patterns;
- and
- means for transmitting signals according to the second time reuse pattern from a second femto cell to an associated user equipment.
A non-transitory computer-readable medium comprising codes for causing a computer to:
- measure signals from a macro cell and one or more neighboring femto cells;
- identify a hybrid automatic repeat request (HARQ) interlace that exhibits the least interference;
- identify a sub frame based on the identified HARQ interlace;
- determine one or more time reuse patterns of the one or more neighboring femto cells;
- select a second time reuse pattern that is less interfering with the one or more time reuse patterns;
- and
- transmit signals according to the second time reuse pattern from a second femto cell to an associated user equipment.
