Abstract:
Disclosed is a method for controlling uplink transmit power in a mobile communication system. A mobile communication includes a first base station and a second base station which are located in two mutually adjacent cells, respectively, at least one base station of the first and second base stations which generate a subframe offset of transmit power (SOTP), and transmits a subframe offset of transmit power generated by at least one base station of the first and second base stations to at least one terminal which belongs to a corresponding cell. Accordingly, it is possible to reduce signaling times for transmit power control, and to accurately control transmit power.
Abstract:
PURPOSE: A control system for MBMS(Multimedia Broadcast Multicast Service) service support is provided to select efficient service area or base station according to the configuration scenario of a service net for broadcasting of multimedia service and multi transmission in a cellular system, thereby providing a MBMA service to a terminal. CONSTITUTION: A transmitting unit(310) transmits a MBMS service request message to a first base station. Based on the MBMS service request message, a receiving unit(330) receives MBMS data from the first base station. In other words, the receiving unit receives MBMS data from a second base station(350) neighbor to the first base station. A handover execution unit(320) performs handover from the first base station to the second base station.
Abstract:
A method and a system for operating cooperative-receiving diversity, and a method and a system for selective and cooperative communication are provided to adopt a selective standard by considering the efficiencies of both a performance improvement effect and a radio resource allocation. An MS(Mobile Station) and an RS(Relay Station) measure the channel quality(S810), and reports the channel quality measurement information to a BS(Base Station)(S820). The BS determines whether or not the MS is a terminal for direct transmission or cooperative relaying(S830). If the MS is for cooperative relaying, the base station calculates an equivalent burst transmission rate(S840). The BS selects one of cooperative communication methods(S850).
