Abstract
The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transceiving an uplink hybrid automatic repeat request (HARQ). According to one embodiment of the present invention, a method for performing a HARQ operation in a terminal of a wireless communication system comprises the steps of: receiving, in a subframe n, an uplink grant message for first uplink data from a base station; determining a first HARQ process from among a plurality of HARQ processes associated with the subframe n; and transmitting, in a subframe n+k, the first uplink data to the base station through the first HARQ process.
Claims11
A method for performing a hybrid automatic repeat request (HARQ) operation by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving an uplink (UL) grant message for first UL data from a base station (BS) at a subframe n;
- determining a first HARQ process from among a plurality of HARQ processes associated with the subframe n;
- and
- transmitting the first UL data to the base station (BS) through the first HARQ process at a subframe n+k,
- wherein a HARQ-ACK response for the first UL data transmitted the subframe n+k is received at the subframe n+k+k*d where ‘d’ is one of natural numbers corresponding to odd numbers.
A user equipment (UE) for performing a hybrid automatic repeat request (HARQ) operation in a wireless communication system, comprising:
- a transmission (Tx) module configured to transmit an uplink signal to a base station (BS);
- a reception (Rx) module configured to receive a downlink signal from the base station (BS);
- and
- a processor configured to control the UE including the transmission (Tx) module and the reception (Rx) module,
- wherein the processor is further configured to:
- receive an uplink (UL) grant message for first UL data from the base station (BS) at a subframe n using the reception (Rx) module,
- determine a first HARQ process from among a plurality of HARQ processes associated with the subframe n, and
- transmit the first UL data to the base station (BS) through the first HARQ process at a subframe n+k using the transmission (Tx) module,
- wherein a HARQ-ACK response for the first UL data transmitted the subframe n+k is received at the subframe n+k+k*d where ‘d’ is one of natural numbers corresponding to odd numbers.
