Apparatus and method for providing HARQ for ranging in a wireless communication system

摘要

An apparatus and method for providing selective Hybrid Automatic Repeat reQuest (HARQ) for a ranging service in a wireless communication system are provided. A HARQ method includes transmitting, to at least one Mobile Station (MS), ranging code division information, and if a ranging code is received from the MS, allocating the MS a resource considering the ranging code, and if a ranging signal is not received through the resource allocated to the MS, making a request for retransmission of the ranging signal to the MS.

1. A method for operating a base station (BS) in a wireless communication system, the method comprising:
transmitting information regarding at least one ranging code to support a soft combining; receiving the at least one ranging code from at least one mobile station (MS); transmitting a first resource allocation message to the at least one MS, the first resource allocation message including resource allocation information for the at least one MS to transmit a ranging signal; and upon no reception of the ranging signal from the at least one MS, transmitting a second resource allocation message to the at least one MS, the second resource allocation message for requesting a retransmission of the ranging signal, wherein the first resource allocation message has a same ranging attributes with the second resource allocation message, and wherein the ranging attributes comprise a frame number index, the at least one ranging code, a ranging symbol, and a ranging subchannel.
