  • Two power control loops for antenna switching transmit diversity
    Patent number: 9357511
    Abstract: Two power control loops for antenna switching transmit diversity are realized by a user terminal including two antennas (110, 120), one power amplifier (140) for amplifying the signals to be transmitted from each of the antennas, and a switch (130) switching the transmission power of the power amplifier from one antenna to the other antenna. Accordingly, the user terminal is enabled to alternately transmit data packets, with its two antennas. A closed loop power control mechanism in the user terminal is adapted to update, on receipt of a transmission power control command from a base station, the transmission power relative to the level of two slots previously.
    Type: Grant

  • Method for transmitting data in packets in a radio communications system
    Patent number: 8223702
    Abstract: The subject matter relates to a method for transmitting data in packets in a radio communications system, according to which the receipt of data packets from at least two terminals is confirmed by a base station of the radio communications. The confirmation of receipt takes place without an overlap in time, using identical resources.

  • DEVICE AND METHOD FOR CONTROLLING UPLINK DATA TRANSMISSION
    Publication number: 20110286399
    Abstract: Device and method to recognize and report the source of interference relate to data transmission between a user terminal and a base station, wherein a pilot signal is transmitted from all antenna assemblies of the user terminal simultaneously, said pilot signals from the user terminal are received by the base station, wherein the base station sends a power control command to the user terminal, corresponding to each of the pilot signals, and wherein the user terminal chooses on receipt of the power control commands, which antenna assembly of the user terminal is used to transmit the next uplink data.
