First Claim
Patent Images
1. A method performed by a network apparatus, the method comprising:
- obtaining acknowledgement (ACK) or negative acknowledgement (HACK) feedback regarding a downlink transmission to a user equipment, said obtaining includingreceiving a first ACK/NACK feedback response in a first subframe from the user equipment via a first uplink transmission resource, andreceiving a plurality of additional ACK/NACK feedback responses from the user equipment, each of the plurality of additional ACK/NACK feedback responses being received in a respective subframe of a second uplink transmission resource that is different from the first uplink transmission resource, wherein each respective subframe of the second uplink transmission resource is a different transmission subframe from the first subframe of the first trans ion resource.

6. A network element comprising:
-
a communications system; a processor; and a memory storing instructions which, when executed by the processor, cause the processor to; obtain acknowledgement (ACK) or negative acknowledgement (NACK) feedback regarding a downlink transmission to a user equipment by receiving a first ACK/NACK feedback response in a first subframe from the user equipment via a first uplink transmission resource and receiving a plurality of additional ACK/NACK feedback responses from the user equipment, each of the plurality of additional ACK/NACK feedback responses being received in a respective subframe of a second uplink transmission resource that is different from the first uplink transmission resource, wherein each respective subframe of the second uplink transmission resource is a different transmission subframe from the first subframe of the first transmission resource. - View Dependent Claims (7, 8, 9, 10)
