摘要： When a radio station terminates a first service on a first radio frequency channel and selects a second radio frequency channel for engaging in a second service, a time delay is inserted after the termination of the first service and before selecting the second radio frequency channel or before engaging in the second service. The time delay is dependent on the state of the radio station and/or a characteristic of the second service.

摘要： A mobile station (100) in a mobile communication system obeys commands received from a serving base station (300) to decrease its transmission rate, and obeys commands received from the serving base station (300) to increase its transmission rate except when a predetermined time period is in progress. It obeys commands received from a non-serving base station (200, 400) to decrease its transmission rate, it initiates the predetermined time period in response to receiving such commands, and it terminates the predetermined time period in response to a further command from the same non-serving base station (200, 400).

摘要： A communication system, for example UMTS (Universal Mobile Telecommunication System), comprises a base station and a plurality of mobile stations. In normal operation the mobile station continuously makes uplink transmissions on certain spread spectrum channels (DPDCH, DPCCH). The maximum allowed power (Pmax) for these uplink transmissions is specified. However there are occasions when for example receiving packet data from the base station, the receiving mobile station has to transmit an acknowledgement (ACK) or a Non-acknowledgement (NACK) at a power level specified by the base station. In order to keep the transmit power of the mobile station within the maximum allowed power, the total power required to transmit an ACK or NACK in parallel with the continuous uplink signals is determined and if this exceeds Pmax then at least the power DPDCH and DPCCH channels are scaled to allow sufficient power for the transmission of an ACK or NACK. The power scaling is carried-out based on the power required for whichever one of ACK or NACK requires the most power. This avoids reducing the amount of time available to a mobile whether an ACK or NACK should be transmitted.

摘要： A secondary station has a receiver capable of resolving signals received (504,510) as a plurality of multipath signals from a plurality of base stations during a soft handover process. In order to decode and act upon the received signals in a very short period of time, an initial subset of received multipath signals is processed (506) to provide an estimate of the action needing to be taken by the station, which action is then implemented by the station (508). Later arriving signals are processed separately (512) and used to update the estimate, as a result of which the action already taken may be corrected (514).Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification.

摘要： A radio communication system comprises a communication channel between a transmitter (108) having a plurality of antennas (110) and a receiver (114) having at least one antenna (110). In such a system the communication channel comprises a plurality of paths (112) having a range of characteristics. Data for transmission is generated by one or more applications (102) and has one or more categories assigned to it, for example by the addition of tags by a tagging block (204) indicating its importance or other requirements. Depending on the assigned categories and the characteristics of the paths (112), the data is mapped to one or more of the transmitter's antennas (110) to select a suitable transmission path (112).

摘要： A secondary station has a receiver capable of resolving signals received as a plurality of multipath signals from a plurality of base stations during a soft handover process. This capability may, for example, be provided by a Rake receiver. In order to decode and act upon the received signals in a very short period of time, signals (402g,402h) arriving after a predetermined time are not processed by the receiver which is able instead to process weaker signals (402d,402e) which arrived before the time (t1).Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification. In this application the predetermined time (t1) is the time after which signals are received too late for use in determining the next power control change.

摘要： The invention provides 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 ensuring that power control of a communication channel has been established before the transmission of data. This is done by delaying initial transmission of a data channel (either at the start of a transmission or after a pause) until after the initial transmission of control channels. In one embodiment the transmission of a data channel can be delayed until adequate power control has been established. These techniques overcome the problem that data transmissions at the start of a data channel are likely to be corrupted if their power level is too low, or to generate extra interference if their power level is too high.

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.
