    摘要： Disclosed are improved retransmission schemes. In one embodiment, a retransmission method includes: receiving, at a protocol layer in a receiver, a data block transmitted from a protocol layer in a transmitter; determining that it is not possible to decode the data block; determining that it is not probable that the data block can be decoded; signaling, from the protocol layer in the receiver, to the protocol layer in the transmitter first feedback information indicating that the data block was received; and signaling, from the protocol layer in the receiver, to the protocol layer in the transmitter second feedback information including information related to the reception time of the data block and indicating that the data block is aborted.

    摘要： A radio network provides centralized load control in order to control uplink interference in a cell while at the same time permitting adaptation to fast channel variations. The radio network sends to a mobile terminal a percentage of time that the mobile terminal may transmit over a radio channel in the uplink direction to the radio network. The mobile determines a current or future condition of the radio channel and restricts uplink transmissions based on the received percentage and the radio channel condition. Transmissions are restricted to times when the current or future condition is favorable up to the percentage amount. Channel condition favorability may be determined by the mobile station, in one example embodiment, by comparing the radio channel condition to an average condition of the channel, such as a local or moving average channel condition. Also in an example embodiment, the mobile may determine a current or future channel condition using transmit power control commands received from the radio network.

    摘要： The present invention compensates for transmit power control time delays between a radio transmitter and receiver that adversely affect the transmit power control process. A time delay associated with a power control loop is compensated for by adjusting a detected signal quality value of a received signal, e.g., signal-to-interference ratio (SIR), based on one or more previous power control commands already sent but whose effect has not yet been experienced. Because the determined signal quality value of the received signal is adjusted based on one or more power control commands already sent but yet to take effect, the transmit power level control command is appropriately determined so that it also takes into account a power control loop time delay. The delay compensation value may be determined based on the output power of a single, previously generated transmit power control command, or on plural previously generated transmit power control commands, depending upon the length of the time delay. If the adjusted signal quality parameter exceeds the target signal quality parameter, the generated power control command directs a decrease in transmit power, and the compensation factor causes a decrease in the subsequently determined signal quality parameter. If the adjusted signal quality parameter is less than the target signal quality parameter, the generated power control command directs an increase in transmit power, and the compensation factor causes an increase in the subsequently determined signal quality parameter.

    摘要翻译： 本发明补偿对发射功率控制过程产生不利影响的无线电发射机和接收机之间的发射功率控制时间延迟。 通过基于已经发送的一个或多个先前的功率控制命令来调整接收信号的检测信号质量值，例如信号干扰比（SIR）来补偿与功率控制回路相关联的时间延迟，但其效果 还没有经验。 由于接收信号的确定的信号质量值是基于一个或多个功率控制命令进行了调整而已经发送但尚未起作用的，所以适当确定发射功率电平控制命令，以便也考虑功率控制环路延时 。 延迟补偿值可以基于单个先前生成的发送功率控制命令的输出功率或者根据时间延迟的长度在多个先前生成的发送功率控制命令上确定。 如果调整后的信号质量参数超过了目标信号质量参数，则生成的功率控制命令指示发送功率的降低，并且补偿因子导致随后确定的信号质量参数的降低。 如果调整后的信号质量参数小于目标信号质量参数，则生成的功率控制命令指示发送功率的增加，并且补偿因素导致随后确定的信号质量参数的增加。
