Abstract: A device and a method for performing handover of a terminal between systems using a different frequency band are provided to reduce time and power needed for scanning by performing unnecessary scanning operation. A terminal transmits an indication signal for informing presence to surroundings after initial access(205). When a handover command message to a small-size base station is received from a base station, the terminal performs a handover procedure to the small-size base station(209).

Abstract: A method for providing the continuity of the peer-to-peer communication when it is difficult to maintain a service due to the influence of the movement of a terminal and the change of a wireless channel condition and an apparatus therefor are provided. A terminal 1(302) performs P2P data communication with the terminal 2(304) through a P2P connection procedure(308). In case the distant between the terminals becomes larger or a radio channel environment is seriously degraded, because it is impossible to maintain the P2P service with limited transmission power, the terminals periodically monitor whether the P2P service can be continuously used by referring to the signal strength of the other parties(310). If it is determined that the continuity of the P2P service is impossible, the terminal 1 transmits a P2P connection request message(312) to a base station 1(300) to request P2P service relay.
Abstract translation: 提供了由于终端的移动的影响以及无线信道条件的改变及其装置难以维护服务而提供对等通信的连续性的方法。 终端1（302）通过P2P连接步骤（308）与终端2（304）进行P2P数据通信。 在终端之间的距离变大或无线电信道环境严重劣化的情况下，由于不可能以有限的发送功率维持P2P业务，所以终端通过参考信号强度来周期性地监视是否可以连续使用P2P业务 的其他方（310）。 如果确定P2P服务的连续性是不可能的，则终端1向基站1（300）发送P2P连接请求消息（312）以请求P2P服务中继。

Abstract: A method for scheduling resources in a wireless communication system is provided to allocate the resources to an MS in consideration of a data rate and a packet generation cycle which can be varied according to time, thereby minimizing a waste of the resources. A method for allocating resources to an MS(Mobile Station) in a wireless communication system comprises the following steps of: enabling the MS to determine whether the generation cycle of a packet to be transmitted is changed(802); notifying a BS(Base Station) of an increase of the packet generation cycle before transmitting an initial packet corresponding to the increased packet generation cycle(804); and receiving the resources in correspondence to the packet generation cycle increased from the BS(806).
Abstract translation: 提供了一种用于在无线通信系统中调度资源的方法，以考虑可根据时间变化的数据速率和分组生成周期将资源分配给MS，从而最小化资源的浪费。 一种用于在无线通信系统中向MS（移动台）分配资源的方法包括以下步骤：使得MS能够确定要发送的分组的生成周期是否改变（802）; 在发送对应于增加的分组生成周期的初始分组之前，通知BS（基站）增加分组生成周期（804）; 以及从BS（806）增加的与分组生成周期对应的资源。

Abstract: An apparatus and a method for allocating resources to a terminal connected with a RS in a broadband wireless communication system are provided to estimate a channel between the terminal connected with the RS, in which a control signal is not repeated, and the RS, thereby selectively allocating resources according to a frequency, determining modulation and encoding schemes, and improving a data transmission rate. A BS(Base Station) apparatus in the wireless communication system of a relay method comprises a transmitter(201) and a scheduler(207). The transmitter transmits a pilot signal transmission request message to a terminal. The scheduler selectively allocates resources to the terminal according to a frequency by using channel information when the channel information estimated from a RS(Relay Station) by using the pilot signal is received.

Abstract: A device for selecting a relay station in a broadband wireless communication system and a method thereof are provided to configure channel information fed back from a receiving port, by using indexes only of a relay station, thereby decreasing an overhead by reducing the quantity of feedback information. A channel estimator(211) estimates channel information with relay stations. An index arranger(213) arranges indexes of the relay stations according to the estimated channel information. A transmitter transmits information on the predetermined number of indexes to a transmission port among the arranged indexes. The channel information refers to a signal to noise ratio. The index arranger(213) arranges the indexes in descending order according to the signal to noise ratio.
