摘要： An apparatus and a method for a terminal handover between systems using different Frequency Allocations (FAs) are provided. The method includes broadcasting an indication signal to inform of existence of the terminal in a coverage of a macro base station to which an indoor base station is registered; and when receiving a handover command message of the indoor base station, from the macro base station, performing a handover procedure to the indoor base station. The base station can efficiently utilize the control channel resource and the user terminal needs not to conduct the unnecessary scanning procedure. Thus, the time and the power required for the scanning can be spared.

摘要： An apparatus and method for transmitting data by using Multi-round Contention Avoidance (MrCA) are provided. The method includes initializing a contention window for each of a plurality of contention rounds and setting a backoff counter corresponding to a size of the contention window for each contention round, starting from a first contention round to a last contention round, decrementing a backoff counter of a corresponding contention round in a time slot unit and transmitting data when the decremented backoff counter is zero and when the corresponding contention round is a last contention round. Accordingly, the number of contending nodes is exponentially decreased for each contention round, resulting in significant decrease in a collision probability in addition to improving fairness on channel use among users.

摘要： Provided is an apparatus and method for transmitting/receiving a message for a handover to a heterogeneous system in a BWA system. In the method, a neighboring BS information message containing the neighboring heterogeneous system BS information is generated according to the neighboring BS information message generation scheme of the serving system. The serving system BS has only to transmit information about a neighboring BS of the serving system, thus reducing a message overhead. Also, the neighboring heterogeneous system BS has only to transmit its own BS information within the corresponding coverage, thus enabling efficient use of control channel resources.
