Claim
1. A method performed by a user equipment to provide acknowledgement (ACK) or negative acknowledgement (NACK) feedback regarding a downlink transmission, the method comprising:
upon receipt of a downlink transmission:
transmitting, by the user equipment, a first ACK/NACK feedback response in a first subframe using a first uplink transmission resource, and
transmitting, by the user equipment, a plurality of additional ACK/NACK feedback responses, each of the plurality of additional ACK/NACK feedback responses being transmitted in a respective subframe using a second uplink transmission resource that is different from the first uplink transmission resource.
2. The method of claim 1, wherein the first uplink transmission resource and the second uplink transmission resource utilize different cyclic shifts.
3. The method of claim 1, wherein the first uplink transmission resource and the second uplink transmission resource utilize different resource blocks.
4. The method of claim 1, wherein each of the plurality of additional ACK/NACK feedback responses is a repetition of the first ACK/NACK feedback response.
5. The method of claim 1, wherein each of the respective subframes is a subframe following the first subframe.
6. The method of claim 1, wherein the first uplink transmission resource is determined based on a location of a physical downlink control channel.
7. The method of claim 1, wherein the first uplink transmission resource is determined based on an index associated with a physical downlink control channel.
8. The method of claim 1, wherein the downlink transmission is a single transmission of a Medium Access Control (MAC) Protocol Data Unit (PDU).
9. A user equipment comprising:
a receiver configured to receive a downlink transmission and
a transmitter configured to provide acknowledgement (ACK) or negative acknowledgement (NACK) feedback upon receipt of the downlink transmission by
transmitting a first ACK/NACK feedback response in a first subframe of a first uplink transmission resource, and
transmitting a plurality of additional ACK/NACK feedback responses, each of the plurality of additional ACK responses being transmitted in respective subframes of a second uplink transmission resource that is different from the first uplink transmission resource.
10. The user equipment of claim 9, wherein the first uplink transmission resource and the second uplink transmission resource utilize a different cyclic shift.
11. The user equipment of claim 9, wherein each of the plurality of additional ACK/NACK feedback responses is a repetition of the first ACK/NACK feedback response.
12. The user equipment of claim 9, wherein the first uplink transmission resource is determined based on a location of a physical downlink control channel.
13. The user equipment of claim 9, wherein the first uplink transmission resource is determined based on an index associated with a physical downlink control channel.
14. A method performed by a user equipment for providing acknowledgement (ACK) or a negative acknowledgement (NACK) feedback, the method comprising:
transmitting, by a transmitter of the user equipment, a first ACK/NACK response corresponding to a downlink transmission, the first ACK/NACK response transmitted in a first subframe using a first uplink transmission resource; and
repeating transmission, by the transmitter of the user equipment, of additional ACK/NACK responses corresponding to the downlink transmission, each of the plurality of additional ACK/NACK responses being transmitted in a respective subframe using a second uplink transmission resource that is different from the first uplink transmission resource.
15. A user equipment for providing acknowledgement (ACK) or a negative acknowledgement (NACK) feedback, the user equipment comprising:
a receiver configured to receive a downlink transmission; and
a transmitter configured to transmit a first ACK/NACK response corresponding to a downlink transmission, the first ACK/NACK response transmitted in a first subframe using a first uplink transmission resource, and repeat transmission of additional ACK/NACK responses corresponding to the downlink transmission, each of the plurality of additional ACK/NACK responses being transmitted in a respective subframe using a second uplink transmission resource that is different from the first uplink transmission resource.
