    • A method of transmitting data in a wireless access system and a packet retransmitting method therein are disclosed. The present invention includes receiving an initial control message including information required for a packet retransmission from a base station, transmitting the packet to be provided with a service from the base station, and if a NACK (non-acknowledgement) signal is received from the base station, retransmitting the packet corresponding to the NACK signal to the base station using the information required for the packet retransmission and included in the initial control message. Therefore, since a separate control message needs not to be transmitted in case of packet retransmission, it is able to save radio resources and reduce an overhead by retransmitting a packet via a previously allocated retransmission region without the separate control message.
    • 公开了一种在无线接入系统中发送数据的方法及其中的分组重传方法。 本发明包括从基站接收包括重发分组所需的信息的初始控制消息,从基站发送要提供服务的分组,以及如果从基站接收到NACK(非确认)信号 使用包重新发送并包含在初始控制消息中的信息,向基站发送与NACK信号对应的分组。 因此,由于在分组重传的情况下不需要发送单独的控制消息,所以能够通过经由先前分配的重传区域重新发送分组来节省无线电资源并减少开销,而没有单独的控制消息。

    • The present invention relates to a broadband wireless connection system, and more particularly, to a method for a base station to more efficiently allocate resources to a terminal, and to an apparatus for performing same. In a broadband wireless connection system according to one aspect of the present invention, a method for a base station for continuously allocating resources comprises the steps of: determining a size and location of a continuous allocation resource to be allocated through continuous resource allocation; comparing the size and location of the determined continuous allocation resource with those of previously allocated continuous allocation resources; and transmitting a map information element (A-MAP IE) including resource allocation information set according to the results of the comparison to a terminal.

    • A method of switching a radio resource mode allocated to a mobile station in a wireless access system is discussed. The method for switching the radio-resource mode allocated to a mobile station in the wireless access system includes, transmitting a first message comprising Carrier to Interference and Noise Ratio (CINR) information of a second radio-resource mode to a base station for requesting a switching from a first radio-resource mode allocated to the mobile station to the second radio-resource mode; and transmitting a predetermined codeword for indicating that the switching from the first radio-resource mode to the second radio-resource mode has not been normally performed, if a second message approving the switching of the radio-resource mode is not received within a predetermined time.
    • 讨论了在无线接入系统中切换分配给移动台的无线资源模式的方法。 用于切换在无线接入系统中分配给移动台的无线电资源模式的方法包括:向基站发送包括第二无线电资源模式的载波干扰和噪声比(CINR)信息的第一消息,用于请求 从分配给所述移动站的第一无线电资源模式切换到所述第二无线电资源模式; 并且如果在预定时间内没有接收到批准无线电资源模式的切换的第二消息,则发送用于指示从第一无线电资源模式到第二无线电资源模式的切换尚未正常执行的预定码字 。
