摘要： In a radio communication system (50) employing closed loop power control a primary station (100) adjusts its transmit power in response to control information including power control commands received from a secondary station (100). If the primary station (100) fails to obey the power control commands the secondary station modifies the control information and the primary station (100) uses the modified control information to adapt a characteristic of a transmission.

摘要： In a radio communication system comprising a primary station (100) and a secondary station (110), the primary station is able to employ one of a plurality of transmission schemes for transmissions to the secondary station. The secondary station determines a quality parameter relating to a downlink channel (122) and from this parameter determines a measurement report to signal to the primary station. The measurement report indicates a suitable transmission power for one transmission scheme, and the primary station is able to determine from a plurality of power offsets between transmission schemes respective transmission powers for a plurality of transmission schemes. The power offsets may be signalled to the primary station by the secondary station. Such a scheme provides sufficient flexibility to handle a wide range of receiver capabilities without the need for excessive signalling.

摘要： A radio communication system includes a communication channel for the transmission of data packets from a primary station to a secondary station. In operation, on detection of a data packet, the secondary station transmits an acknowledgement signal to the primary station to indicate the status of the received data packet, and resets a timer. While the timer is running, the secondary station modifies a characteristic of uplink transmissions. In one embodiment the modification includes the secondary station transmitting a negative acknowledgement for each time at which a data packet could have been transmitted if no indication of a data packet is received. In another embodiment the modification includes the secondary station altering a parameter relating to transmission of channel quality information to the primary station.

摘要： A method of conformance testing of a secondary station for use in a radio communication system which permits a soft handover process in which the secondary station engages in communication with a plurality of primary stations. The method permits testing the response of the secondary station to power control commands received simultaneously from each of the plurality of primary stations instructing it to adjust its output transmission power. In particular, the method enables testing the secondary station's assessment of the reliability of the power control commands received from each primary station, which has not been possible previously. The test is performed by transmitting known sequences of power control commands to the secondary station from each of the primary stations, then comparing the actual pattern of changes in output transmission power with the expected pattern of changes.

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 applying power control in steps of variable size at the start of a transmission, using a large step size initially which is reduced as the power approaches a target value. In one embodiment the step size is reduced when the sign of a power control command reverses, while in another embodiment the step size is reduced after a predetermined time. These techniques reduce the time taken for power control to be established, thereby addressing the problem that data transmissions at the start of a data channel 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 packets of data (214) to transmit to a primary station while not actually engaged in a call. The primary station transmits a random access channel availability (AV) message (302) once per frame to inform secondary stations about the resources currently available. Hence a secondary station can select a channel known to be free. If no channels are available the secondary station can avoid a wasted access attempt.
