    Abstract: Disclosed is a scheduling system and method in a mobile communication system. In the algorithm applied to the scheduling system and method, a packet loss probability on an input real-time traffic packet is calculated, different weights are assigned depending on the condition whether the calculated packet loss probability exceeds the maximum packet loss requirement probability, and a priority metric is determined. In this instance, the weights are established to be higher as the calculated packet loss probability approaches the maximum packet loss. The packet scheduling process is performed according to the determined priority metric. The above-noted scheduling algorithm guarantees the maximum packet loss rate in the real-time traffic, and increases system capacity.

    Abstract: Disclosed is a random access data transmission system and method using OFDMA. The system includes a scheduling ID into an access grant on a preamble for a random access, and transmits it together with an acknowledgment or a non-acknowledgment of the preamble, a base station uses the scheduling ID to notify the mobile station of a random access data transmittable time and a data transmission channel through a control channel, and the mobile station transmits a preamble in advance. After receiving a transmission assignment instruction corresponding to a scheduling ID through the control channel, the mobile station transmits random access data through an assigned channel.

    Abstract: The present invention relates to a method of transmitting/receiving random access response information in a radio communication system, and a base station and a terminal thereof. According to the invention, in a case where a base station of a radio communication system transmits response information for random access processing requested from terminals, the base station determines whether to transmit non-contention-based response information and contention-based response information for each of one or more terminals, which requests random access, by one radio resource. When determining to be transmitted by one radio resource, the base station transmits the random access response information configured by the non-contention-based response information and the contention-based response information for each of one or more terminals. In addition, when determining to be transmitted by separate radio resources, the base station transmits the random access response information configured by the non- contention-based response information or the contention-based response information for each of one or more terminals. Accordingly, since the response information is efficiently configured from the point of view of allocation and utilization of radio resources, it can support variable and flexible utilization of physical layer radio resources.

    Abstract: Provided is a method for indicating a mobile station maintaining radio resource control (RRC) connection but not maintaining uplink physical layer synchronization to receive downlink signals when packet data to be transmitted to the mobile station are generated to thereby make the mobile station start uplink signal transmission. The method includes: (a) allocating a random access preamble index and generating a downlink signal reception indication message including the allocated random access preamble index in a base station; (b) transmitting the generated downlink signal reception indication message to the mobile station; (c) forming a response message to random access, when a preamble signal designated by the random access preamble index is transmitted from the mobile station in response to the downlink signal reception indication message; and (d) transmitting the response message to random access to the mobile station to thereby control uplink physical layer synchronization.

    Abstract: The present invention relates to a wireless communication system that counts UEs using an MBMS, and a method thereof. The wireless communication system is connected with a UE through a radio link, and includes a Node B and a controlling radio network controller (CRNC). The Node B receives sequence setting information on a sequence included in a preamble transmitted from the UE from a network manager. The CRNC controls the Node B, detects a sequence according to whether to use an MBMS based on the sequence setting information, and performs a counting process for counting UEs based on whether the UE uses the MBMS. According to the present invention, counting of UEs using an MBMS can be efficiently performed by using a predetermined sequence. Particularly, the counting process can be simplified by reducing complexity in access probability management of a network manager, thereby increasing efficiency in data transmission by reducing signaling for random access probability and omitting a random access probability calculation process.
