摘要： A radio system and a channel allocation method in a radio system are provided. The radio system and method have at least one base station communicating with terminals within a coverage area thereof. Air interface resources are allocated to different terminals with a combined time and code multiple access method such that the signal of one or more terminals is transmitted in each time slot. Terminal signals are grouped into different time slots based on connection characteristics of each terminal.

摘要： The aim of the invention is to restrict the maximum transmitted power used by a mobile communication device. In most countries there are regulations in force which impose certain maximum limits on the power of electromagnetic radiation directed towards humans. These limits vary from country to country and will most probably be tightened in the future. In the system according to the invention, the upper limit of transmitted power is varied according to the mode of usage of the mobile communication device. A mobile communication device according to such a system meets the requirements made on a device operating close to the user's head, but the same mobile communication means may still be used in applications demanding greater transmitted power in a situation where the power limits placed on the radio set are less strict.

摘要： In mobile communications systems of the CDMA type in particular detection of individual signals from the received common signal with known methods requires much processing capacity of the mobile communications system. The present invention concerns a method of reducing radio inter-ference in a mobile communications system including at least one base station (BS) and several mobile stations (MS). The mobile communications system uses several traffic channels for communications between the base station (BS) and the mobile stations (MS). The method according to the invention is characterized in that signals received at the same reception point are classified therein into at least two classes according to the interference tolerance of the signal or according to the interference caused by the signal to other signals and/or according to the complexity of decoding of the signal, a special way of functioning is defined for each class, whereby the total interference caused by received signals to one another is reduced by complying with these ways of functioning, and the individual signals of each class are processed at the point of reception in the way of functioning defined for the class in question.

摘要： Apparatus, and an associated method, for a UWC-136 HS communication system is provided. A synchronization signal generated by the network infrastructure, constructed generally corresponding to the existing IS-136/136+ standard is received by a mobile station operable, generally, pursuant to the timing scheme defined in a GSM system. A relative timing offset between the timing schemes of the respective communication system schemes is determined and thereafter utilized for purposes of synchronization.
