Abstract
A method and apparatus for dynamic acknowledgement repetition for a downlink medium access control packet data unit transmission ‘MAC PDU’ requiring multiple acknowledgements, the method having the steps of: receiving the downlink MAC PDU requiring multiple acknowledgements; and utilizing a differentiating factor and acknowledgement scheme, sending the multiple acknowledgements.

1-25. (canceled)
A method, comprising:
- receiving, at a User Equipment (UE), a message regarding a second differentiating factor;
- transmitting, by the UE, a first acknowledgement (ACK) or negative acknowledgement (NACK) feedback using a first differentiating factor, wherein the first differentiating factor is determined based on a physical downlink control channel (PDCCH);
- and
- transmitting, by the UE, a second ACK or NACK feedback using the second differentiating factor, wherein the second differentiating factor is a cyclic shift.
A user equipment comprising:
- a receiver configured to receive a message regarding a second differentiating factor;
- and
- a transmitter configured to transmit a first acknowledgement (ACK) or negative acknowledgement (NACK) feedback using a first differentiating factor, wherein the first differentiating factor is determined based on a physical downlink control channel (PDCCH), and transmit a second ACK or NACK feedback using the second differentiating factor, wherein the second differentiating factor is a cyclic shift.
A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause a computing device to perform operations comprising:
- receiving, at a user equipment (UE), a message regarding a second differentiating factor;
- transmitting, by the UE, a first acknowledgement (ACK) or negative acknowledgement (NACK) feedback using a first differentiating factor, wherein the first differentiating factor is determined based on a physical downlink control channel (PDCCH);
- and
- transmitting, by the UE, a second ACK or NACK feedback using the second differentiating factor, wherein the second differentiating factor is a cyclic shift.
A method, comprising:
- transmitting, from an enhanced node B (eNB) to a user equipment (UE), a message regarding a second differentiating factor;
- receiving, from the UE, a first acknowledgement (ACK) or negative acknowledgement (NACK) feedback based on a first differentiating factor, wherein the first differentiating factor is based on a physical downlink control channel (PDCCH);
- and
- receiving, from the UE, a second ACK or NACK feedback based on the second differentiating factor, wherein the second differentiating factor is a cyclic shift.
An enhanced node B (eNB) comprising:
- a transmitter configured to transmit a message regarding a second differentiating factor to a user equipment (UE);
- and
- a receiver configured to receive, from the UE, a first acknowledgement (ACK) or negative acknowledgement (NACK) feedback based on a first differentiating factor, wherein the first differentiating factor is based on a physical downlink control channel (PDCCH), and receive, from the UE, a second ACK or NACK feedback based on the second differentiating factor, wherein the second differentiating factor is a cyclic shift.
