Abstract: A communication method of a terminal that can operate in a relay mode or a base station mode is provided. When the terminal, having received a service from a first base station, detects that a service connection to the first base station is unavailable, the terminal searches for a second base station, which is an available neighboring base station. The terminal transmits a ranging request message including a base station identifier of the first base station to the second base station.

Abstract: In a direct communication between terminals, a terminal transmits a synchronization channel preamble part after transmitting a synchronization channel message part including synchronization information. The terminal receives a dedicated channel including a direct communication packet after transmitting the synchronization channel preamble part. A transition time gap for switching from transmission to reception may be inserted to an end of the synchronization channel preamble part.

Abstract: A method of controlling a base station is disclosed that provides service to a first terminal and a second terminal having higher priority than the first terminal. The base station determines whether there is an influx of call connection attempts when the lower-priority terminal and the higher-priority terminal perform ranging. If it is determined that there is an influx of call connection attempts, the base station sets the initial ranging backoff window size included in an information element of S-SFH SP3 (Secondary-Superframe Header SubPacket3) to a first size. If it is determined that there is an influx of call connection attempts, the base station sets the initial ranging backoff window size for the second terminal in an AAI-SCD (Advanced Air Interface-System Configuration Descriptor) message to a second size. Accordingly, it is possible to achieve a high probability of success of initial ranging of a higher-priority terminal.
Abstract translation: 公开了一种控制基站的方法，其向第一终端和具有比第一终端优先级高的第二终端提供服务。 当低优先级终端和较高优先级终端执行测距时，基站确定是否存在呼叫连接尝试的涌入。 如果确定存在呼叫连接尝试的流入，则基站将包括在S-SFH SP3（Secondary-Superframe Header SubPacket3）的信息元素中的初始测距退避窗口大小设置为第一大小。 如果确定存在呼叫连接尝试的涌入，则基站将AAI-SCD（高级空中接口 - 系统配置描述符）消息中的第二终端的初始测距退避窗口大小设置为第二大小。 因此，可以实现较高优先级终端的初始测距的高成功概率。
