摘要： Provided is a channel mode converting method of a wireless portable Internet system. When a diversity channel mode is converted into an Adaptive Modulation and Coding (AMC) channel mode, a radio resource for transmitting Channel Quality Information (CQI) is allocated without responding to a resource allocation request and a request between a terminal and an access point. Therefore, a delay time can be reduced on the channel mode conversion. In addition, a CQI channel for transmitting the existing channel quality information is released and a CQI channel for a new channel is allocated on the channel mode conversion. As a result, a time for changing the diversity channel CQI transmission to the AMC channel CQI transmission at the physical layer can be easily synchronized for transmitting the REP_RSP at the MAC.

摘要： A method for resolving a collision in a communication system using medium access control based on contention. The method enables management and control of a contention window size of each mini slot and thus all the terminals may have an equal opportunity to access each mini slot. Moreover, when two or more terminals have simultaneously attempted to access any one mini slot and thus collision has occurred in the mini slot, the method restricts the access of the mini slot to the terminal or terminals that had experienced collision, and then permits an access attempt of another terminal after all the terminals which had experienced collision succeed in accessing a mini slot.

摘要： A method of requesting resources, a method of allocating resources, and an apparatus therefor by using bandwidth request ranging in a mobile communication system are provided. The method of allocating uplink resources to a subscriber station by using bandwidth request ranging in a mobile communication system includes: transmitting an uplink channel descriptor (UCD) including code group information to the subscriber station, wherein the code group information is obtained by dividing a bandwidth request code into a plurality of groups and mapping the groups to predetermined data block sizes; receiving a bandwidth request code selected in the subscriber station; determining a code group including the selected bandwidth request code; and allocating a bandwidth through which a data block size corresponding to the determined code group can be transmitted, to the subscriber station. Accordingly, bandwidth request codes are divided into code groups of which bandwidth request codes represent specific block sizes, and the base station that receives the bandwidth request code allocates uplink resources corresponding to the bandwidth request code, so that it is possible to decrease a transmission delay of the uplink traffic.
