  • Publication number: 20060062323
    Abstract: A method for controlling the transmission of signals in a communications system uses a polling trigger which prevents a deadlock condition from occurring between a transmitter and receiver. The method includes selecting a protocol data unit from a buffer, determining whether the data unit is located at a predetermined position within a transmission window, and then transmitting polling information with the data unit if the data unit is determined to be at the predetermined position of the transmission window. The predetermined position is preferably a last position of the window. If the data unit is not in a last position of the transmission window, additional steps of the method include determining whether the data unit is a last-stored data unit in a transmission buffer. If so, polling information is transmitted with the data unit. If neither polling trigger is satisfied, the data unit is transmitted without polling information.

  • Publication number: 20060007886
    Abstract: The present invention relates to transmitting data units of a radio protocol layer, wherein one logical channel identifier is added to one or more data units belonging to one logical channel. Because only one logical channel identifier is added to the data units belonging to one logical channel in constructing a MAC-e PDU, overheads of the MAC-e PDU are reduced. Such reduction of the PDU overheads increases data throughput, which is advantageous for a high-speed data communication system, such as the HSUPA.

  • Publication number: 20050286472
    Abstract: The present invention relates to combining point-to-multipoint service data in a mobile terminal of a wireless communication system. A mobile terminal receiving MBMS service data of a current cell in a MAC entity while concurrently receiving the same MBMS service data from a neighboring cell in a MAC entity discards any received data not related to MBMS. Accordingly, any unnecessary operation of the terminal in simultaneously receiving the MBMS service from different cells is minimized. Thus, the mobile terminal effectively receives the MBMS service.

  • Publication number: 20050286483
    Abstract: The present invention relates to notifying updated control information of a point-to-multipoint service in a wireless communications system. An indication about whether control channel information has been updated is transmitted and received during a time interval where data of the point-to multipoint service is not transmitted between a network and a mobile terminal. Furthermore, and indication about whether the control channel information has been updated is transmitted and received via a physical channel, to which a traffic channel is mapped. This allows the mobile terminal, which receives data of a specific point-to-multipoint service discontinuously, to effectively recognize whether the control channel information has been updated.

  • Publication number: 20050272459
    Abstract: The present invention relates to a method for referencing a physical channel carrying point-to-multipoint service data in a wireless communication system. The present invention utilizes an identifier to reference specific physical channel configurations previously sent to a mobile terminal from a network. The identifier may reference an entry in a list of physical channel configuration in a specific message. Alternatively, a physical channel configuration in a first message is first allocated a specific identity. Then, a specific identifier referencing the specific identity is used in a second message to identify the physical channel configuration in the first message.

  • Publication number: 20050255836
    Abstract: The present invention relates to transmitting and receiving a notification of control information for a point-to-multipoint service. Preferably, a mobile terminal receives notification information from a network during a first period. The mobile terminal then determines to receive a control channel during a second period for receiving a control information message according to the notification information. After, the mobile terminal receives the control information message for the point-to-multipoint service during the second period if the mobile terminal determines to receive the control information message during the second period.

  • Publication number: 20050249140
    Abstract: The present invention relates to a method for indicating the validity of a channel configuration. Configuration information for establishing the reception of a physical channel carrying point-to-multipoint services is sent via a point-to-multipoint control channel to a mobile terminal. Validity information is sent together with the configuration information for indicating to the mobile terminal when or how long the configuration information is valid. The configuration information may be valid during a current modification period, after a given activation time, or up to a given activation time. Thus, a mobile terminal can avoid using an invalid physical channel configuration.

  • Publication number: 20050213583
    Abstract: To minimize data loss as a mobile terminal unnecessarily reads an MBMS control channel (MCCH) in the course of receiving MBMS data, an MBMS control information reception indication message comprising attribute information of control information for an MBMS service is transmitted to the mobile terminal. The mobile terminal then selectively reads the MCCH to receive the control information according to the attribute information contained in the indication message.

  • Publication number: 20050180378
    Abstract: In an apparatus and paging method for a broadcast and multicast service (MBMS) in a mobile communication system, a network transmits a terminal paging indication channel (PICH) frame and an MBMS paging indication channel (MICH) frame such that the MICH frame is transmitted after a certain time from the transmission of the PICH frame. A mobile terminal receives the PICH frame during a discontinuous reception (DRX) cycle, and only when MICH indication information is included in the PICH frame does the mobile terminal recieve the MICH frame. Thus, power consumption of the mobile terminal is considerably reduced.
