摘要： In a radio communication system having a primary station and a plurality of secondary stations, the power of uplink and downlink channels between the primary station and a secondary station is controlled in a closed loop manner by each station transmitting power control commands to the other station. In response to these commands the receiving station adjusts its output power in steps.By combining a plurality of received power control commands before adjusting its output power the receiving station may emulate the ability to use a smaller power control step size than its minimum, thereby improving performance under certain channel conditions. In one embodiment when the required power control step size is less than the minimum step size of a particular station, that station processes a group of power control commands to determine whether to adjust its output power by its minimum step size. In an alternative embodiment the power control step size is fixed when the combining algorithm is used. The invention is applicable to power control in both primary and secondary stations.
摘要翻译：在具有主站和多个次站的无线电通信系统中，主站和次站之间的上行链路和下行链路信道的功率以闭环方式由每个站向另一个站发送功率控制命令来控制。响应于这些命令，接收站逐步调整其输出功率。通过在调整其输出功率之前组合多个接收的功率控制命令，接收站可以模拟使用比其最小值小的功率控制步长的能力，从而改善在某些信道条件下的性能。在一个实施例中，当所需功率控制步长小于特定站的最小步长时，该站处理一组功率控制命令以确定是否将其输出功率调整其最小步长。在替代实施例中，当使用组合算法时，功率控制步长是固定的。本发明适用于主站和次站的功率控制。

摘要： A radio communication system comprises a communication channel for the transmission of data packets from a primary station (100) to a secondary station (110). In response to receipt of a data packet, the secondary station transmits an acknowledgement signal to the primary station indicating the status of the received data packet. The signal is selected from a set of at least two available signal types (for example positive and negative acknowledgements, ACK and NACK), and the power at which it is transmitted depends on the type of the signal.In one embodiment NACKs are transmitted at a higher power than ACKs, thereby reducing the chance of the primary station misinterpreting a NACK as an ACK. In another embodiment a REVERT signal is used to request retransmission of a previous packet. The REVERT signal may be identical to the NACK signal but transmitted at a higher power.

摘要： A radio communication system comprises a communication channel for the transmission of data packets (302) from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement (304) or a negative acknowledgement (306)) to the primary station for each of the plurality of packets. The signaling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.

摘要： A radio communication system has means for improving power control of a communication channel for the transmission of data after an interruption in the transmission. This is done by adjusting the transmission power immediately after the interruption by an offset from the power used before the interruption. The offset may be fixed or may be determined from the transmission power in the period before the interruption. This technique reduces, on average, the time taken for power control to be re-established, thereby addressing the problem that data transmissions immediately after the interruption are likely to be corrupted if the power level is too low, or to generate extra interference if the power level is too high.
摘要翻译：无线电通信系统具有用于在传输中断之后改善用于传输数据的通信信道的功率控制的装置。这是通过在中断之后立即调整发射功率与在中断之前使用的功率的偏移来完成的。偏移量可以是固定的，或者可以在中断之前的时段内由发送功率确定。平均来说，这种技术平均减少了重新建立功率控制所需的时间，从而解决了如果功率电平太低，中断后立即数据传输可能会被破坏的问题，或者如果功率水平太高。
