Abstract
Methods and apparatus for providing cross-cell signaling and/or coordination for interference mitigation in wireless communication networks are described. In one aspect, a UE associated with a serving eNB may receive control signaling from another non-serving eNB in a different cell. The control signaling may be consistent with a characteristic of the serving eNB and associated cell. In another aspect, multiple eNBs may coordinate transmission of DL resources to minimize collisions of control signaling resources.

A method for coordinated transmission between nodes in a wireless communication system, the method comprising:
- determining, between a first base station and a second base station, a downlink (DL) channel resource configuration for a DL channel including a control channel, the DL channel resource configuration being determined to minimize interference between the second base station and a user equipment (UE) served by the first base station;
- and
- transmitting, from the second base station, control channel signals in accordance with the DL channel resource configuration.
A computer program product comprising a computer-readable medium including codes for causing a computer to:
- determine, between a first base station and a second base station, a downlink (DL) channel resource configuration for a DL channel including a control channel, the DL channel resource configuration being determined to minimize interference between the second base station and a user equipment (UE) served by the first base station;
- and
- send, from the second base station, control channel signals in accordance with the DL channel resource configuration.
A communications device, comprising:
- a processor module configured to determine, between a first base station and a second base station, a downlink (DL) channel resource configuration for a DL channel including a control channel, the DL channel resource configuration being determined to minimize interference between the second base station and a user equipment (UE) served by the first base station;
