Apparatus for controlling hybrid automatic repeat request (HARQ) in a mobile communication system
First Claim
1. An apparatus for use in a mobile communication system that simultaneously transmits a control message over a control channel and data over a data channel, wherein the apparatus supports hybrid automatic repeat request (HARQ), the apparatus comprising:
- a physical layer for receiving the control message and the data from the control channel and the data channel respectively and for decoding the received control message and data;
a physical layer'"'"'s HARQ controller for processing a result of the decoding of at least one of the received control message and data and for controlling the physical layer according to a result of the processing,the physical layer'"'"'s HARQ controller comprising;
two HARQ state machines for receiving state information from the physical layer and determining a state transition to next state,wherein the two HARQ state machines are selectively enabled based on a number of acknowledgement/negative-acknowledgement (ACK/NAK) processing delay time slots.

Abstract
An apparatus for controlling a Hybrid Automatic Repeat Request (HARQ) is provided. In the apparatus, a physical layer includes a decoder for decoding a control message received over the packet data control channel, a demodulator for demodulating packet data received over the packet data channel, and a turbo decoder for decoding the demodulated packet data. A physical layer'"'"'s HARQ controller determines whether to demodulate and decode the received packet data depending on a decoding result of the control message, outputs the decoded control message to the demodulator and the turbo decoder for demodulation and decoding of the received packet data, controls output of a response signal according to decoding result of the packet data, and delivers the turbo-decoded packet data to an upper layer.
