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 the downlink transmission:
transmitting, by the user equipment, a first ACK/NACK feedback response corresponding to the downlink transmission in a first subframe using a first cyclic shift, and
transmitting, by the user equipment, a plurality of additional ACK/NACK feedback responses corresponding to the same downlink transmission, each of the plurality of additional ACK/NACK feedback responses corresponding to the same downlink transmission being transmitted in a respective subframe using a respective cyclic shift different from the first cyclic shift used by the first ACK/NACK response corresponding to the same downlink transmission.
2. 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.
3. The method of claim 1, wherein each of the respective subframes is a subframe following the first subframe.
4. The method of claim 1, wherein the first ACK/NACK feedback response is transmitted using a first uplink transmission resource, and the first uplink transmission resource is determined based on a location of a physical downlink control channel.
5. The method of claim 1, wherein the first ACK/NACK feedback response is transmitted using a first uplink transmission resource, and the first uplink transmission resource is determined based on an index associated with a physical downlink control channel.
6. The method of claim 1, wherein the downlink transmission is a single transmission of a Medium Access Control (MAC) Protocol Data Unit (PDU).
7. 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 corresponding to the downlink transmission in a first subframe using a first cyclic shift, and transmitting a plurality of additional ACK/NACK feedback responses corresponding to the same downlink transmission, each of the plurality of additional ACK responses corresponding to the same downlink transmission being transmitted in a respective subframe using a respective cyclic shift different from the first cyclic shift used by the first ACK/NACK response corresponding to the same downlink transmission.
8. The user equipment of claim 7, wherein each of the plurality of additional ACK/NACK feedback responses is a repetition of the first ACK/NACK feedback response.
9. The user equipment of claim 7, wherein the first ACK/NACK feedback response is transmitted using a first uplink transmission resource, and the first uplink transmission resource is determined based on a location of a physical downlink control channel.
10. The user equipment of claim 7, wherein the first ACK/NACK feedback response is transmitted using a first uplink transmission resource, and the first uplink transmission resource is determined based on an index associated with a physical downlink control channel.
11. 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 cyclic shift; and
repeating transmission, by the transmitter of the user equipment, of additional ACK/NACK responses corresponding to the same downlink transmission, each of the plurality of additional ACK/NACK responses corresponding to the same downlink transmission being transmitted in a respective subframe using a respective cyclic shift different from the first cyclic shift used by the first ACK/NACK response corresponding to the same downlink transmission.
12. 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 the downlink transmission, the first ACK/NACK response transmitted in a first subframe using a first cyclic shift, and repeat transmission of additional ACK/NACK responses corresponding to the same downlink transmission, each of the plurality of additional ACK/NACK responses corresponding to the same downlink transmission being transmitted in a respective subframe using a respective cyclic shift different from the first cyclic shift used by the first ACK/NACK response corresponding to the same downlink transmission.
13. 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 the downlink transmission:
transmitting, by the user equipment, a first ACK/NACK feedback response corresponding to the downlink transmission in a first subframe using a first cyclic shift;
transmitting, by the user equipment, a second ACK/NACK feedback response corresponding to the same downlink transmission in a second subframe using a second cyclic shift different from the first cyclic shift; and
transmitting, by the user equipment, a third ACK/NACK feedback response corresponding to the same downlink transmission in a third subframe using the second cyclic shift, wherein the second ACK/NACK feedback response and third ACK/NACK feedback response are repetitions of the first ACK/NACK response.
14. 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 corresponding to the downlink transmission in a first subframe using a first cyclic shift, transmitting a second ACK/NACK feedback response corresponding to the same downlink transmission in a second subframe using a second cyclic shift different from the first cyclic shift, and transmitting a third ACK/NACK feedback response corresponding to the same downlink transmission in a third subframe using the second cyclic shift, wherein the second ACK/NACK feedback response and third ACK/NACK feedback response are repetitions of the first ACK/NACK response.
