Abstract
A method and apparatus for fast interference signaling is provided. The method may include configuring, by an evolved node B (eNB), at least one user equipment to indicate to the eNB when an activity state of at least one interferer changes. Based on the indicated activity state, the eNB can schedule the at least one user equipment in muted subframes of the interferer or almost blank subframes (ABS).
Claims30
A method, comprising:
- configuring, by an evolved node B (eNB), at least one user equipment to indicate to the eNB when an activity state of at least one interferer changes;
- and
- based on the indicated activity state, scheduling the at least one user equipment in muted subframes of the interferer or almost blank subframes (ABS).
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to
- configure at least one user equipment to indicate to the apparatus when an activity state of at least one interferer changes;
- and
- based on the indicated activity state, schedule the at least one user equipment in muted subframes of the interferer or almost blank subframes (ABS).
A computer program, embodied on a computer readable medium, the computer program configured to control a processor to perform a process, comprising:
- configuring at least one user equipment to indicate when an activity state of at least one interferer changes;
- and
- based on the indicated activity state, scheduling the at least one user equipment in muted subframes of the interferer or almost blank subframes (ABS).
A method, comprising:
- measuring a relative difference in interference in muted and other subframes of an interferer;
- and
- indicating to an evolved node B (eNB) when an activity state of the interferer changes based on the measuring.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to
- measure a relative difference in interference in muted and other subframes of an interferer;
- and
- indicate to an evolved node B (eNB) when an activity state of the interferer changes based on the measuring.
A computer program, embodied on a computer readable medium, the computer program configured to control a processor to perform a process, comprising:
- measuring a relative difference in interference in muted and other subframes of an interferer;
