    摘要: A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.

    摘要: Methods for improving uplink communications in a Wideband Code Division Multiple Access (WCDMA) communication system, wherein mobile terminals can transmit at various transmission power levels. In a mobile terminal, the method includes the steps of receiving a configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; when the mobile terminal performs a non-scheduled transmission, it transmits according to the parameters contained in the configuration message. In a network node, the method includes the steps of transmitting to at least one mobile terminal the configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; and, adjusting a power setting for the transmission of acknowledgement or negative-acknowledgement messages from the wireless network to one or more of mobile terminals.

    摘要: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.
