    摘要： Mechanisms for efficient transmission of large amount of download data from a base station (210) to a user equipment (220) in a multi-carrier that minimizes power consumption on the user equipment are described. When multiple component carriers are to be used to transmit the download data, the base station (210) informs the user equipment (220). The base station (210) transmits on the anchor carriers without wait after informing the user equipment (220) and transmits on the non-anchor carriers after waiting a predetermined delay. The predetermined delay provides time to allow the user equipment (220) to activate the receiving resources and be ready to receive the download data over the non-anchor carriers. In this manner, the user equipment (220) can be in a power conservation mode and activate the receiver resources only when needed.

    摘要： Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore "UP" transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.

    摘要： A transmitter that may have marginal power availability is enabled to autonomously retransmit previously transmitted frames containing the same data. The transmitter sends an initial frame to a base transceiver station (BTS) and immediately retransmits the same frame without regard to any ACK/NAK transmission from the BTS. The retransmissions are accumulated in the receiver and decoded after a sufficient quantity of the frame is transmitted. After receiving the last retransmitted frame the BTS sends an ACK/NAK to the transmitter that is accepted.

    摘要： The present invention relates to a transmit power control method and to a user equipment of a telecommunications network system. According to the method, transmit power control commands intended for traffic and control channels respectively, are received; the commands being separately identified by resources. The method further comprises, applying common commands which occupy the same resources and apply separate commands which occupy different resources. The TPC commands are intended for the traffic and control channels.
