摘要： A method for transmission of control information from a primary station to at least one secondary station, includes transmitting with a first set of control information parameters control information corresponding to data transmission with a first set of data parameters, and transmitting with a second set of control information parameters control information corresponding to data transmission with a second set of data parameters. At least one control information parameter has a difference in value between the two sets of control information parameters, where the difference in value has a dependency on the difference between the value of a data parameter in the first set of data parameters and the value of the data parameter in the second set of data parameters. The data parameter is a different parameter from the at least one control information parameter.

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.
