摘要： A radio station comprises means for allocating resources for communication with at least one other station, and including means for mapping data to be transmitted from at least the radio station to the at least one other station, and means for applying a cyclic shift to the data mapping, wherein this cyclic shift is adjusted depending on the number of data blocks to be mapped. A possible implementation concerns the mapping of the DVRB (Distributed Virtual Resource Block) in OFDM.

摘要： A method of operating a communication system in which transmissions in a first direction, say from a base station, comprise frames formed by data packets and transmissions in a second direction, say from a user equipment (U E), comprise substantially continuous transmissions having acknowledgement fields (ARQ-A, ARQ-B) for data packets and transmission gaps (GP) to allow the UE to make other measurements. The acknowledgement fields are mapped to the data packets to enable the base station to determine which data packets are being acknowledged. In order to avoid ambiguity in mapping acknowledgement fields to data packets when a transmission gap occurs, a single data packet is transmitted in either the frame whose acknowledgement field would occur in the transmission gap or the frame whose acknowledgement field would occur immediately following the transmission gap. Thus the base station will know that the acknowledgement field immediately following the transmission gap maps onto the data packet transmitted in the selected one of the two frames. In one embodiment a data packet is not transmitted in the frame whose acknowledgement field would occur immediately following the transmission gap. In a refinement of the method, the selection of the particular frame is related to the one which can support a high rate data packet.

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： 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： 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 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.
