TL;DR: In this paper, the authors proposed a handover protocol for a broadband wireless communication system including a serving base station communicating with the SS, and at least one neighbor BS neighboring the serving BS.

TL;DR: In this paper, a method for transmitting a ranging code from a base station to subscriber stations to prevent collision during a random access by the subscriber stations in an OFDM/OFDMA communication system was proposed.

TL;DR: In this paper, the authors proposed a method for transmitting common control information from a base station to a plurality of subscriber stations in a wireless communication, which includes first information transmitted in common to all of the subscribers and second information separately transmitted to the subscribers according to channel states of the subscriber stations, where the first information is transmitted using an MCS (Modulation and Coding Scheme) level having a lowest order and a coding scheme with the lowest coding rate among all MCS levels available in the base station.

TL;DR: In this paper, the authors propose a method for assigning ranging codes in the OFDM/OFDMA communication system, which includes classifying rangings between a base station and a mobile subscriber station (MSS) of an OFDM-OFDM communication system into an initial ranging, a periodic ranging, bandwidth request ranging, and a handover ranging.
