1. A method of providing co-channel interference information by a network node, the method comprising:
- receiving information for at least one user equipment (UE) connected to an adjacent network node;
determining a co-channel interference list for user equipment (UE) connected to the network node wherein the co-channel interference list is based on the received information; and
transmitting the co-channel interference list to a UE connected to the network node.

12. A computer program comprising computer readable program modules which when run on a network node causes the network node to:
-
receive information for at least one active user equipment (UE) connected to an adjacent network node; determine a co-channel interference list for user equipment (UE) connected to the network node wherein the co-channel interference list is based on the received information; and transmit the co-channel interference list to a UE connected to the network node.

13. A method of improving reception performance of a user equipment connected to a serving cell, the method comprising the steps of:
-
detecting adjacent cells; measuring a signal strength value of the detected cells; storing the detected cells and corresponding measured signal strength value; receiving a co-channel cell interference list; comparing an identity of cells in the received list with an identity of the stored cells to identify matching cells; and utilizing the identity of the matched cells to improve a decoding performance of data received by the user equipment. - View Dependent Claims (14, 15, 16)

17. A user equipment comprising:
-
a communication interface for communicating with a serving cell; a cell search unit for detecting neighboring cells in a cell search process and for receiving a co-channel interference list from the serving cell; a processor for measuring signal strengths of the detected cells; and a memory for storing an identity of the detected cells and the measured signal strength values wherein the processor further determines which of a cell identification of the cells in the co-channel interference list belong to cells in the detected list and uses the determined information to improve decoding at the user equipment.
