STRUCTURE AND CONSTRUCTION METHOD OF UPLINK CONTROL CHANNEL IN MOBILE WIDEBAND WIRELESS ACCESS SYSTEM
摘要
<p>The present invention relates to an uplink control channel configuration in a mobile wideband wireless access system, and an allocation method thereof. An uplink control channel includes a long cyclic prefix used to improve interference and distortion caused by multipath transmission characteristics of an initial ranging or handover ranging signal and a periodic ranging or band request ranging signal. In addition, a short orthogonal frequency division multiple (OFDM) symbol is used to transmit uplink control information when one terminal exists or the number of terminals is small.</p>
