Method for operation of HARQ in a broadband wireless access communication system
First Claim
1. A method supporting a Hybrid Automatic Repeat Request (HARQ) between a subscriber station and a base station in a broadband wireless access communication system including, the method comprising the steps of:
- transmitting at least one HARQ enabled uplink burst from the subscriber station to the base station;
generating ACKnowlegment/Negative ACKnowlegment (ACK/NACK) information according to the received at least one HARQ enabled uplink burst at the base station;
mapping the generated ACK/NACK information to a bitmap at the base station; and
transmitting the bitmap through a downlink information from the base station to the subscriber station.

Abstract
Provided is a method supporting a Hybrid Automatic Repeat Request (HARQ) between a subscriber station and a base station in a broadband wireless access communication system. The method includes transmitting at least one HARQ enabled uplink burst from the subscriber station to the base station; generating ACKnowledgment/Negative ACKnowledgment (ACK/NACK) information according to the received HARQ enabled uplink burst at the base station; mapping the generated ACK/NACK information to a bitmap at the base station; and transmitting the bitmap through a downlink information from the base station to the subscriber station.

6. A method supporting a Hybrid Automatic Repeat Request (HARQ) between a subscriber station and a base station in a broadband wireless access communication system including, the method comprising the steps of:
-
generating a downlink information indicating a HARQ ACKnowledgment (ACK) region and at least one HARQ enabled downlink burst at the base station; transmitting the downlink information from the base station to the subscriber station; generating ACK/NACK information according to the received HARQ enabled downlink burst at the subscriber station; and transmitting the generated ACK/NACK information through the H-ARQ ACK region from the subscriber station to the base station. - View Dependent Claims (7, 8, 9)

10. A method for operating a Hybrid Automatic Repeat Request (HARQ) scheme for a downlink by a subscriber station in a broadband wireless access communication system including the subscriber station and a base station, the method comprising the steps of:
-
determining a type of HARQ enabled downlink burst being transmitted by analyzing an information element corresponding to a connection identifier of the subscriber station, after receiving a downlink Mobile Application Part (MAP) message belonging to a corresponding frame; when the HARQ enabled downlink burst being transmitted is a new burst, confirming transmission of the new burst and information of the HARQ enabled downlink burst, and receiving the HARQ enabled downlink burst in a downlink data region; when the HARQ enabled downlink burst being transmitted is a retransmitted burst, confirming retransmission of an already transmitted burst and information of the HARQ enabled downlink burst, and receiving the HARQ enabled downlink burst in a downlink data region; determining if the received HARQ enabled downlink burst has an error; and transmitting one of an ACKnowledgement (ACK) message and a Negative ACKnowledgement (NACK) message through a sub-channel in accordance with the determining for the error. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for operating a Hybrid Automatic Repeat Request (HARQ) scheme for an uplink by a base station in a broadband wireless access communication system, the method comprising the steps of:
-
determining at least one subscriber station to which a base station will transmit a HARQ enabled burst through a corresponding uplink frame; determining information of the HARQ enabled burst of the at least one subscriber station; determining a type of the HARQ enabled burst by analyzing an information element corresponding to the determined subscriber station; when the HARQ enabled burst being transmitted is a new burst, preparing an uplink Mobile Application Part (MAP) message to be transmitted to the subscriber station, preparing an information element corresponding to the uplink MAP message, and receiving the HARQ enabled burst targeting the base station in an uplink data region; when the HARQ enabled burst being transmitted is a retransmitted burst, preparing an Incremental Redundancy (IR) scheme, preparing the uplink MAP message to be transmitted to the subscriber station, preparing an information element corresponding to the uplink MAP message, and receiving the HARQ enabled burst targeting the base station in the uplink data region; determining if the received HARQ enabled burst has an error; preparing one of an ACKnowledgment (ACK) message and a Negative ACKnowledgement (NACK) message in a form of bitmap, in accordance with a result of the determining; and transmitting the one of the ACK message and the NACK message. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
