| 20090168729 | Method for controlling data transmission - A method for controlling data transmission comprising following steps of: obtaining transmission delays and time differences between a RNC and respective base stations by the RNC; configuring cells and a common channel for data transmitting by the RNC; controlling a start time of data transmission of each cells by the RNC; informing a UE of a frame offset and a chip offset of the common channel through an interface Uu by the RNC; and receiving configuration parameters of the common channel transmitted from the RNC by the UE. In the present invention, merging of signals transmitted from different cells via the common channel has been achieved so that the quality of signals received by the UE has been improved and the throughput of the system has been enlarged. | 07-02-2009 |
| 20090176495 | Provision of a Multimedia Broadcast/Multicast Service (MBMS) for a User Equipment Moving Along Cells in a Cellular Mobile Communication System - Procedures are provided for the establishment of MBMS services in different cells of a cellular telecommunications network, in particular, for maintaining the transmission of MBMS data to a particular user equipment, even when it moves from one cell to another when the service is provided in different ways in different cells. In particular, when a user equipment receives a multimedia data service in a first cell via a certain type of connection (i.e., a point-to-point connection/while requiring an RRC Connection, a point-to-multipoint connection without/while requiring an RRC Connection), and moves to a second cell where the type of connection used to provide the service is different, specific actions are undertaken (e.g., request for an RRC Connection, release of an RRC Connection, etc), depending on the type of connection change carried out. Embodiments for the establishment of the most adequate connection (p-t-p, p-t-m) in a cell are disclosed as well (e.g., by sending a message from a SRNC to a CRNC). | 07-09-2009 |

| 20100070815 | VIRTUAL EXTENSION OF CRC LENGTH - An apparatus and method for generating a Scheduling Assignment (SA), which reduces a probability of an incorrect action by a User Equipment (UE) in response to a reception of the SA, in a communication system wherein a base station transmits the SA being a first type or a second type and including at least one Information Element (IE). The method includes setting at least one bit in the at least one IE with an arbitrary value, if the SA is of the first type; setting the at least one bit in the at least one IE with a predetermined value, if the SA is of the second type; and setting any remaining bits in the at least one IE with arbitrary values. | 03-18-2010 |
| 20100112956 | Radio link failure detection method and apparatus for wireless communication system - A radio link failure detection method of a user equipment transitioning between a Discontinuous Reception (DRX) mode and non-DRX mode cyclically in a wireless communication system includes transitioning between a Discontinuous Reception (DRX) mode and a non-DRX mode in a wireless communication system. The method also includes adjusting, when a mode transition occurs, a size of a monitoring window for a transitioned operation mode; reporting a radio channel condition acquired by monitoring and averaging the channel condition within the monitoring window; and repeating adjustment of the monitoring window size and report of the radio channel condition while moving the monitoring window as time progress. | 05-06-2010 |
| 20100118815 | DISCONTINUOUS RECEPTION CONTROL METHOD OF USER EQUIPMENT IN WIRELESS COMMUNICATION SYSTEM - A Discontinuous Reception (DRX) control method and apparatus are provided for determining a start time of the duration period of DRX operation in a wireless communication system using a short DRX cycle and a long DRX cycle. A DRX control method of a user equipment of the present invention includes determining one of a long DRX mode and a short DRX mode, configuring, when the short DRX mode is selected, the short DRX mode with a start time determined based on short DRX parameters, and configuring, when the long DRX mode is selected, the long DRX mode with a start time determined based on long DRX parameters. | 05-13-2010 |
| 20100169733 | TRANSMISSION CONTROL METHOD FOR HARQ IN MOBILE COMMUNICATION SYSTEM - A transmission control method for HARQ is provided for improving HARQ performance in a mobile communication system. The transmission control method for Hybrid Automatic Repeat reQuest (HARQ) in a mobile communication system according to the present invention includes receiving an downlink resource assignment message; determining whether configured downlink assignment has been indicated to an HARQ entity since a previously received downlink assignment for a User Equipment's (UE's) Cell-Radio Network Temporary Identifier (C-RNTI) for the same HARQ process; maintaining, if the configured downlink assignment has not been indicated to the HARQ entity, the HARQ process; and processing, if the configured downlink assignment has been indicated to the HARQ entity, the downlink resource assignment message as a resource assignment message for initial transmission. | 07-01-2010 |
| 20100182973 | METHOD AND APPARATUS FOR TRANSMISSION IN BUNDLING MODE IN WIRELESS COMMUNICATION NETWORK - A method and apparatus for a transmission in a bundling mode are provided to prevent a conflict between a bundling transmission resource and other transmission resource in a wireless communication network. A bundling transmission method includes determining whether there is a transmission conflicting with a bundling transmission induced by an uplink grant regarding uplink transmission resources. If it is determined that there is a conflicting transmission, the method disregards at least one of the bundling transmission and the conflicting transmission. A bundling transmission apparatus includes a retransmission unit and a transmission control unit, which are configured to execute the bundling transmission method. | 07-22-2010 |
