user equipment identity;

access point identity; and

interference sequence identity.

5. A method as set forth in claim 1 , wherein the method comprises providing at least one of the following:

an absolute level of interference; and

a relative level of interference.

6. A method as set forth in claim 1 , wherein the method comprises:

receiving configuration information from the node for configuring the measuring and providing;

wherein the providing comprises:

providing, to the node at a time in accordance with the configuration information, a first information regarding the co-channel interference measurement and a second information regarding the cross-channel interference measurement.

7. 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 to, with the at least one processor, cause the apparatus at least to:

measure separately co-channel interference and cross-channel interference to produce a co-channel interference measurement and a cross-channel interference measurement distinct from the co-channel interference measurement;

provide, to a node, information regarding each of the co-channel interference measurement and the cross-channel interference measurement, the node being configured to use the information for scheduling transmissions for the apparatus; and

provide a channel state information message for at least one dominant interferer.

8. An apparatus as set forth in claim 7 , wherein the apparatus is configured to provide an average cross-channel interference value for a plurality of interferers in the channel state information message.

9. An apparatus as set forth in claim 7 , wherein the information comprises an identity of at least one interferer.

an absolute level of interference; and

a relative level of interference.

12. An apparatus as set forth in claim 7 , wherein the apparatus is configured to:

receive configuration information from the node for configuring the measuring and providing;

wherein the causing the apparatus to provide comprises causing the apparatus to:

provide, to the node at a time in accordance with the configuration information, a first information regarding the co-channel interference measurement and a second information regarding the cross-channel interference measurement.

13. A method comprising:

receiving, at an apparatus, separate cross-channel interference information and co-channel interference information for at least one user equipment, the cross-channel interference information and the co-channel interference information having been measured at the at least one user equipment, the cross-channel interference information being distinct from the co-channel interference information;

using the information for scheduling transmissions for a set of user equipment; and

receiving a channel state information message for at least one dominant interferer.

14. A method as set forth in claim 13 , wherein the information is provided in a channel state information message; and

wherein the method comprises receiving an average cross-channel interference value for a plurality of interferers in the channel state information message.

15. A method as set forth in claim 13 , wherein the method comprises receiving at least one of:

an indication of an absolute level of interference; and

an indication of a relative level of interference.

16. A method as set forth in claim 13 , wherein the scheduling comprises scheduling transmit and receive periods of each user equipment in the set of user equipment.

17. A method as set forth in claim 13 , wherein the scheduling comprises scheduling of a physical downlink shared channel.

18. A method as set forth in claim 13 , wherein the method comprises providing configuration information to the at least one user equipment.
