Abstract
Methods and apparatuses for improving HARQ feedback in shortened TTI in a wireless communication system are disclosed herein. In one method, a user equipment is configured with a processing interval between receiving a downlink data and transmitting a corresponding acknowledgement (ACK)/negative acknowledgement (NACK) response. The UE receives downlink data with 1 millisecond TTI at a downlink subframe. The UE transmits the ACK/NACK response of the downlink data on a resource at an uplink subframe, wherein the resource is based on an offset value if the processing interval is shorter than 4 milliseconds.
Claims20
A method for improving hybrid automatic repeat request (HARD) feedback, the method comprising:
- receiving, by a user equipment (UE), a signal of configuration of a processing interval between receiving a downlink data and transmitting a corresponding acknowledgement (ACK)/negative acknowledgement (NACK) response;
- receiving, by the UE, downlink data with 1 millisecond TTI at a downlink subframe;
- and
- transmitting, by the UE, the ACK/NACK response of the downlink data on a resource at an uplink subframe, wherein the resource is based on an offset value if the processing interval is shorter than 4 milliseconds.
A method for improving hybrid automatic repeat request (HARD) feedback, the method comprising:
- receiving, by a first UE, a first signal of configuration of a first processing interval between receiving downlink data and transmitting corresponding ACK/NACK response, wherein the first processing interval is shorter than 4 milliseconds;
- receiving, by the first UE, downlink data with 1 millisecond TTI;
- transmitting, by the first UE, the ACK/NACK response of the downlink data on a first resource at an uplink subframe, wherein the first resource is determined based on an offset value;
- receiving, by a second UE, a second signal of configuration of a second processing interval, wherein the second processing interval is equal to 4 milliseconds;
- receiving, by the second UE, downlink data with a 1 millisecond TTI;
- and
- transmitting, by the second UE, the ACK/NACK response of the downlink data on a second resource at the uplink subframe, wherein the second resource is not based on the offset value.
A User Equipment (UE), comprising:
- a control circuit;
- a processor installed in the control circuit;
- and
- a memory installed in the control circuit and coupled to the processor;
- wherein the processor is configured to execute a program code stored in the memory to:
- receive a signal to configure the UE with a processing interval between receiving a downlink data and transmitting a corresponding acknowledgement (ACK)/negative acknowledgement (NACK) response;
- receive downlink data with 1 millisecond TTI at a downlink subframe;
- and
- transmit the ACK/NACK response of the downlink data on a resource at an uplink subframe, wherein the resource is based on an offset value if the processing interval is shorter than 4 milliseconds.
