Abstract: Disclosed is a method for quickly and conveniently establishing a connection between a master terminal and a slave device communicating with each other using Bluetooth. The slave device implements a special direct connection mode in which the slave device can be directly connected to the master terminal. When a user operates the slave device, the direct connection mode can be selected. The slave device notifies the master terminal of the direct connection mode.

Abstract: A pilot reference transmission scheme well suited for high data rate wireless communication systems is disclosed. To maximize the amount of interference from transmissions from neighboring transmission sources (e.g., access points or base stations) during the pilot interval, and hence minimize the amount of interference from non-transmitting sources during the data intervals, the pilot references are transmitted in bursts at predetermined time intervals, and the pilot bursts from the access points are synchronized. This results in maximum interference contributions from non-transmitting neighboring access points, facilitating reliable estimation of worst case carrier-to-interference (C/I), and further allows the receiving devices (e.g., access terminals) to easily recognize the bursts as pilot reference. In one embodiment, each access point transmits the pilot bursts at or near its maximum transmit power level and no user-specific data is transmitted during the pilot bursts.

Abstract: A method for transmitting radio resources in a mobile communication system is disclosed. The method includes receiving a random access channel (RACH) preamble from a plurality of UEs and transmitting response information associated with the received preambles over a common channel wherein the plurality UEs can access the common channel and receive corresponding information. If a HARQ scheme is used when a UE transmits data to the eNode-B using uplink radio resources allocated over the RACH, the eNode-B does not pre-allocate uplink radio resources required for re-transmission and performs allocation of radio resources for a first transmission of HARQ. If the re-transmission is required, the eNode-B allocates the radio resources required for the re-transmission with the NACK signal. If re-transmission is not required, the present invention can reduce an amount of wasted radio resources.

Abstract: In a centralized radio network consisting of several devices one device acts as master or network coordinator and has a transmission range. Basically, other devices of the network are able to adopt the role of a coordinator. This ability is used to enlarge the area of the network to a size larger than the transmission range of the master. A device asks its parent PNC to become a child PNC when a newly turned on device acts as a temporary PNC and broadcasts an initiation beacon indicating that it looks for a child PNC. The child PNC reports that it is available. The new device determines one of the available child PNCs to be its new master. The acknowledgment for the selected child PNC may be broadcasted to inform all the devices in the transmission range of the new device. The new device quits the role of the temporary PNC and associates to the existing network.
