    摘要: A system and method of operating a radio communication system uses a random access channel to enable a secondary station to transmit a message to a primary station. The secondary station transmits a preamble to the primary station. After successful receipt of the preamble the primary station transmits a control channel including power control information to instruct the secondary station to adjust the output power of its transmitter. This ensures that the secondary station transmits at a sufficient power for the message to be received successfully by the primary station, while minimizing interference generated by the transmission.

    摘要: A radio communication system comprises a secondary station having a communication channel with a primary station for the transmission of data packets from the primary station to the secondary station. In response to receipt of a data packet, the secondary station transmits a combined acknowledgement and quality parameter signal (402) to the primary station. The signal (402) indicates whether the data packet was received correctly and the value of the quality parameter enables the primary station to select transmission parameters for further data transmissions. A range of formats for the combined signal are possible.In one embodiment the quality parameter is a site selection signal indicating a preferred subset of primary stations for subsequent data transmissions. In another embodiment the quality parameter relates to the quality of the radio link and enables the primary station to select suitable modulation and coding schemes and/or transmit power levels.

    摘要: A radio communication system a primary station and a secondary station operating according to two (or more) two-way communication modes. An uplink and/or a downlink communication channel is present for the first mode, but only one of an uplink and a downlink channel is present for the second mode. Modifications to the protocols of the first and second modes enable the traffic for an absent communication channel of one mode to be carried by the corresponding channel of the other mode.

    摘要: A device with a display is operable in at least two modes, a first mode in which display data is provided to the screen for viewing in a first orientation and a second mode in which display data is provided to the screen for viewing in a second, orthogonal, orientation. In the first mode, the display data fills the screen, and in the second mode the display data comprises two images for filling the screen. The aspect ratio for at least one of the two images in the second mode can then be the same as for the image in the first mode.

    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: A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station. Such a channel is intended for use by secondary stations having data (214) to transmit to a primary station while not actually engaged in a call. By enabling access requests (202) to be transmitted with a greater range of possible signatures, a much greater number of degrees of freedom is available to a secondary station requesting access to a random access channel. This enables significantly improved efficiency of resource allocation by increasing the amount of information transmitted to the primary station by the access request (202).

    摘要: A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station. Such a channel is intended for use by secondary stations having data (214) to transmit to a primary station while not actually engaged in a call. A secondary station requesting access chooses a signature corresponding to the resource it requires to encode an access preamble (202). It may be known, from a resource availability message (402) broadcast by the primary station, that certain resources are unavailable. In this case the primary and secondary stations dynamically re-assign signatures corresponding to the unavailable resources to available resources, thereby reducing the probability of collisions between different secondary stations requesting the same resource.
