摘要： A communication device (1) for communicating in a multiple channel communication system comprises means (9) for calculating an effective noise level of one of the channels of the system by applying an expectation operator to an estimated noise level affecting the channel based on time varying characteristics of the estimated noise level. The calculation of the effective noise level may also be based on an estimated path loss. The calculation of the effective noise level may also be based on an initial power level allocated to the respective channel. The effective noise level calculated for each channel may be employed in calculating power levels to be allocated to the respective channels.

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 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.

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.
