Downlink Inter-Cell Interference Cancellation with Cell Aggregation Coordinated Multi-Point
First Claim
1. A method, comprising:
- receiving at a user equipment from a network access node a temporary identifier associated with an interference cancellation group to which the user equipment is assigned;
decoding a control channel using the temporary identifier to determine a downlink resource allocation for the user equipment and to determine a downlink resource allocation for at least one other user equipment assigned to the same interference cancellation group; and
receiving a downlink signal in accordance with the determined downlink resource allocation for the user equipment while canceling interference from the downlink signal that is associated with the at least one other user equipment by using the determined downlink resource allocation for the at least one other user equipment.

Abstract
A method includes receiving at a user equipment from a network access node a temporary identifier associated with an interference cancellation group to which the user equipment is assigned; decoding a control channel using the temporary identifier to determine a downlink resource allocation for the user equipment and to determine a downlink resource allocation for at least one other user equipment assigned to the same interference cancellation group; and receiving a downlink signal in accordance with the determined downlink resource allocation for the user equipment while canceling interference from the downlink signal that is associated with the at least one other user equipment by using the determined downlink resource allocation for the at least one other user equipment. Apparatus for performing the method are also disclosed.

9. An apparatus, comprising:
-
a processor; and a memory including computer program code, where the memory and computer program code are configured to, with the processor, cause the apparatus at least to receive at a user equipment from a network access node a temporary identifier associated with an interference cancellation group to which the user equipment is assigned;
to decode a control channel using the temporary identifier to determine a downlink resource allocation for the user equipment and to determine a downlink resource allocation for at least one other user equipment assigned to the same interference cancellation group; and
to receive a downlink signal in accordance with the determined downlink resource allocation for the user equipment and to cancel interference from the downlink signal that is associated with the at least one other user equipment by using the determined downlink resource allocation for the at least one other user equipment. - View Dependent Claims (10, 12, 13, 14, 15)

16. A method, comprising:
-
assigning a plurality of user equipment to an interference cancellation group having an associated temporary identifier; informing the user equipment of the interference cancellation group of the temporary identifier; transmitting on a control channel a plurality of downlink control information corresponding to the plurality of user equipment assigned to the interference cancellation group, each downlink control information containing a unique identifier of one of the plurality of user equipment and at least a downlink resource allocation grant for the user equipment, where transmitting encodes the plurality of downlink control information using the associated temporary identifier. - View Dependent Claims (17, 18, 19)
