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.
摘要翻译：提供了一种使用多轮避免避免（MrCA）发送数据的装置和方法。该方法包括：对于多个争用回合中的每一个初始化争用窗口，并且从第一争用轮到最后一个争用轮从第一争用轮到第一争用轮设置对应于每个争用轮的争用窗口的大小的退避计数器，递减倒退计数器在时隙单元中相应地进行争用，并且当递减的退避计数器为零时以及当对应的争用轮次是最后的争用轮次时发送数据。因此，竞争节点的数量对于每个争用轮次指数地减少，导致冲突概率的显着降低，除了提高用户之间信道使用的公平性。

摘要： An apparatus and method for transmitting an UpLink (UL) pilot using a scanning interval in a mobile communication system are provided. The method includes receiving a scanning response message including information on a UL pilot channel allocation mode from a serving Base Station (BS), measuring each DownLink (DL) channel state using DL signals of one or more neighboring BSs and transmitting a UL pilot to each of the one or more neighboring BSs in the UL pilot channel allocation mode, during a scanning duration. Accordingly, both UL and DL Quality of Service (QoS) may be considered during a handover operation.

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.

摘要： A method and an apparatus ensure efficient handover in a wireless communication system even when a User Equipment (UE) moves at a high speed. A serving eNB receives interference power information of an uplink (UL) signal and interference increase/decrease information of the UL signal from at least one adjacent eNB. an adjacent eNB, for which the received interference power information indicates that interference power of the UL signal is equal to or greater than a threshold value, is selected as a target eNB for a User Equipment (UE) among the at least one adjacent eNB. Whether handover of the UE is delayed is determined based on the interference increase/decrease information received from the target eNB. And if the handover of the UE is delayed, a handover parameter is transmitted to the UE to perform handover to the target eNB.
摘要翻译：即使当用户设备（UE）以高速移动时，方法和设备也确保无线通信系统中的有效切换。服务eNB从至少一个相邻eNB接收上行链路（UL）信号的干扰功率信息和UL信号的干扰增减信息。在所述至少一个相邻eNB中，选择所述接收到的干扰功率信息指示所述UL信号的干扰功率等于或大于阈值的相邻eNB作为用户设备（UE）的目标eNB。基于从目标eNB接收的干扰增加/减少信息确定UE的切换是否被延迟。如果UE的切换被延迟，则向UE发送切换参数以执行到目标eNB的切换。
